[0061] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, it should be noted that the orientations or positional relationships indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] Example 1

[0063] This embodiment provides an assembly system for a terminal and a base, such as Figure 1 As shown, it includes a base frame, a locking device c, a first conveying mechanism f1, a material dividing device b, a second conveying mechanism f2, a detection device e, a clamping device d, a loading device, and a third conveying mechanism f3.

[0064] The base frame is provided with a first station, a second station, a third station, a fourth station and a fifth station; a locking device is provided at the second station of the base frame, for locking the screws and the copper sheets to form terminals; the first conveying mechanism f1 conveys the terminals on the second station to the dividing device b at the fourth station for dividing the terminals according to different types or batches; the classified terminals are conveyed to the detection device e at the fifth station through their respective corresponding second conveying mechanisms f2, and the detection device e detects the color of the copper sheets in the terminals and the orientation of the conductive contacts on the copper sheets; the qualified terminals are taken away from the detection device through the clamping device d and conveyed to the first station, ready to be installed in the corresponding installation cavity on the base.

[0065] At the same time, the feeding device includes a second feeding mechanism a for feeding the base to the second carrier at the third station, and two first feeding mechanisms for feeding screws and copper sheets to the second station respectively; the third feeding mechanism feeds the second carrier carrying the base at the third station to the first station; then the clamping device at the first station installs the terminal into the installation cavity of the base to realize the installation process of the terminal and the base. The second carrier is pre-placed on the third feeding mechanism, and optionally, the third feeding mechanism and the first feeding mechanism are both belt conveyors.

[0066] like Figure 1 As shown, optimally, the base frame as a whole is a U-shaped workbench, the first feeding mechanism, the locking device, the first conveying mechanism, the dividing device, the second conveying mechanism and the detection device are arranged in sequence on one side of the U-shaped workbench, the second feeding mechanism a is arranged on the other side of the U-shaped base frame, and the third conveying mechanism is arranged on the third side of the U-shaped workbench corresponding to the slot, so that the structure of the entire terminal and base assembly system is compact and the space occupied is small.

[0067] like Fig.28 As shown, it is a schematic diagram of the terminal h5 in the switch, the assembly h51 of the screw and gasket in the terminal, the copper sheet h52, the position of the small airplane h2 on the base h3, and the coordination on the second carrier h1.

[0068] For locking devices, Figures 2 to 12 As shown, it includes a first mold base c1, a second mold base, a first transfer mechanism, two first feeding mechanisms c4 and a plurality of screw locking components c5.

[0069] like Figure 6 As shown, the first mold base c1 and the second mold base c2 are staggered in the vertical direction and are slidably arranged on the first base c8 on the base frame in the same direction in the horizontal direction, and the projections of the first mold base c1 and the second mold base c2 in the horizontal direction are staggered. The first mold base c1 is located above the second mold base. Figure 7 and Figure 8 As shown, the first mold base and the second mold base c2 are respectively provided with a plurality of spaced first placement cavities c115 and a plurality of spaced second placement cavities c22. Of course, the number of the first placement cavity and the number of the second placement cavity can be one or more.

[0070] The first placement cavity c115 and the second placement cavity c22 have similar structures. The first placement cavity c115 is a groove structure and has three notches. The three notches are distributed at the top of the groove, and the groove is perpendicular to the sliding direction of the first mold base c1 ( Fig. 9 The two side walls in the first direction (horizontal direction) of the front-to-back direction are provided with the two notches as first openings c112 ( Fig. 9 middle right port) and the second port c113 ( Fig. 9 The left opening in the middle); and horizontally protruding and spaced bosses c114 are provided on the two inner walls opposite to the groove, and the top surfaces of the two bosses c114 form an overlap position. For example, before the screw is locked with the copper sheet, a gasket is pre-assembled on the screw rod part of the screw, and the two ends of the gasket overlap the two bosses c114, and the screw is suspended in the groove. As a variation, the top notch mentioned above may not be provided on the top of the first placement cavity.

[0071] like Figure 8 As shown, the second placement cavity c22 replaces the horizontal boss c114 of the first placement cavity c115 with a horizontal recessed slot c21, and the inner cavities of the two slots c21 form an overlap position, for example, the two ends of the copper sheet are respectively embedded in a slot c21, so that the copper sheet is suspended in the second placement cavity c22. As a variation, the structure of the first placement cavity can be interchangeable with the second placement cavity.

[0072] Two first loading mechanisms c4 are arranged on the first base c8 and convey workpieces into the first placement cavity c115 and the second placement cavity c22 respectively. For the convenience of description, the two first loading mechanisms c4 are respectively described as the first loading mechanism ' and the first loading mechanism '. The first unloading port of the first loading mechanism ' is connected with and communicated with the first opening c112 of the first placement cavity c115, and the screw slides downward through the first unloading port and slides into the first placement cavity c115 through the first opening c112, so as to realize conveying the assembly of the screw and the gasket into the first placement cavity c115; the second unloading port of the first loading mechanism ' is connected with and communicated with the first opening c112 of the second placement cavity c22, and the copper sheet slides downward through the second unloading port and slides into the second placement cavity c22 through the first opening c112, so as to realize conveying the copper sheet into the second placement cavity c22.

[0073] As for the structure of the first feeding mechanism c4, it can be any existing first conveying mechanism or feeding structure, preferably, as Fig.12 As shown, the first feeding mechanism c4 includes a first vibration bin c41 that is driven by a vibrator c43 to vibrate, and the first vibration bin c41 has a placement cavity; the starting end is arranged on the outer wall of the placement cavity, and a first feeding channel c42 is spirally arranged outside the placement cavity and inclined downward, and the end of the first feeding channel c42 serves as a discharge port. The first combination of screws and gaskets or copper sheets falls into the first feeding channel c42 through the vibration of the first vibration bin c41, and slides downward in the first feeding channel c42, thereby realizing the delivery of screws or copper sheets to the corresponding placement cavities. Of course, a first conveying track c44 can also be provided at the discharge port, and the outlet of the first conveying track c44 serves as the final discharge port.

[0074] When sliding, any one of the first mold seat c1 and the second mold seat c2 can switch between a material receiving state in which the respective placement cavity is connected to the discharge port of the corresponding first loading mechanism c4 and a material blocking state in which the respective placement cavity is blocked at the respective corresponding discharge port, so that when only one workpiece is placed in each placement cavity, the first loading mechanism c4 will no longer transport the workpiece into the placement cavity. Only after the workpiece in the placement cavity is assembled and removed, and the mold seat is reset to the place cavity and connected to the corresponding discharge port again, the first loading mechanism c4 will transport the workpiece into the corresponding placement cavity again.

[0075] For example, Figure 7As shown, the mold base includes a mold body c11 and a blocking component c12. The mold body c11 is provided with a placement cavity and is driven by a driving assembly to slide back and forth on a first base c8; the blocking component c12 is fixed to one end of the body along the sliding direction of the body, and the top of the blocking component c12 is at least higher than the bottom of the corresponding placement cavity in the vertical direction; optimally, the top of the blocking component is flush with the top notch of the groove, and in the material receiving state, the placement cavity is connected to its corresponding discharge port; in the material blocking state, the blocking component c12 slides on the side wall facing the suction port and blocks the corresponding discharge port.

[0076] Optimally, as Fig. 9 As shown, the first mold seat c1 is located at Fig. 9 The second mold seat c2 is located at the front side of Fig. 9 The first loading mechanism ' and the first loading mechanism "are respectively arranged on the right side of the first mold base c1 and the second mold base c2 and avoid the first transfer mechanism. Assuming the starting position, the first unloading port and the second unloading port are respectively Fig. 9 The first opening of the first placement cavity and the first opening of the second placement cavity are connected and communicated, and the two mold seats are in a material receiving state.

[0077] After the first combination of the screw and the gasket is placed in the first placement cavity c115, the first placement cavity c115 is Fig. 9 The first mold base c115 slides backward in the first placement cavity c115, at this time, the first placement cavity c115 is horizontally staggered with the first material discharge port, and the side wall of the blocking component c12 of the first mold base c1 keeps sliding against the first material discharge port during the backward sliding, blocking the first material discharge port, so that the first material discharge port cannot realize the material discharge function, and the first mold base is in a material blocking state; on the contrary, when the first combination of the screw and the gasket in the first placement cavity c115 is taken away by the first transfer mechanism, the first mold base c115 is in a material blocking state. Fig. 9 The first mold base is in a state of receiving materials. Optionally, the blocking component c12 is in the form of a plate.

[0078] like Figure 5As shown, the drive assembly includes a track c231 fixed on the first base c8, and a first slider c232 slidably arranged on the track, the above-mentioned mold body is fixed on the first slider, and a first cylinder fixedly connected to the first slider, so that the mold body is driven to slide back and forth on the track through the telescopic movement of the first cylinder. Optionally, the mold body is L-shaped, the blocking component c12 is fixed on the vertical part of the L-shape, the placement cavity is arranged on the vertical part of the L-shape, and the horizontal part of the L-shape is fixed on the first slider. Optimally, the drive assembly corresponding to the first mold base c1 and the drive assembly corresponding to the second mold base c2 are respectively located Figure 5 The first transfer mechanism and the screw locking component c5 are conveniently arranged on the right and left sides of the first fixing plate c81 of the first base c8. Figure 5 The right side of the first fixing plate c81 is convenient for locking the copper sheet and the screws on the right side.

[0079] The first transfer mechanism is disposed on the first base c8 and is used to transfer the workpiece on the first placement cavity c115 to the second placement cavity c22. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first transfer mechanism includes a first lifting mechanism c31, a first clamping assembly c32 and a first pushing mechanism c91.

[0080] The first lifting mechanism c31 is fixed on the first base c8; the first clamping assembly c32 has a clamping cavity; it is fixed on the first lifting mechanism and driven by the first lifting mechanism to perform lifting movement; the projection of the clamping cavity in the horizontal direction falls on the projection of the sliding path of the second placement cavity c22 (for example Figure 5 In the front-to-back direction), and in the first direction, it can be flush with the first placement cavity c115 in the horizontal direction (for example Figure 5 The bottom of the clamping cavity and at least one side wall along the first direction are respectively a first opening and a second opening; Figure 8 and Fig.10 As shown, the first opening can be connected to the top notch c111 of the second placement cavity c22, and the second opening is connected to the second opening c113 of the first placement cavity c115; the first pushing mechanism is telescopically arranged on the first base c8 relative to the clamping cavity along the first direction, and is used to push the workpiece in the first placement cavity c115 into the clamping cavity connected thereto.

[0081] When the first transfer mechanism needs to transfer the screws in the first placement cavity c115 to the second placement cavity c22, the first mold base c1 is first Figure 5 or Fig. 9 The first clamping assembly c32 moves upward or downward, so that the first placement cavity c115 of the first mold base c1 is in the first direction ( Figure 5 or Fig. 9 The first mold base c1 is horizontally aligned with the clamping cavity and connected to the clamping cavity in the left and right directions. The second opening of the first placement cavity is connected to the clamping cavity. Then, the first pushing mechanism is extended to extend into the first placement cavity c115 through the first opening c112 to push the first combination of the screw and the gasket into the clamping cavity along the first direction through the second opening c113, thereby transferring the first combination of the screw and the gasket into the clamping cavity. At this time, the first mold base c1 is reversely slid back to reset ( Fig. 9 Then, the second mold seat c2 is in the state of receiving the material; Figure 5 or Fig. 9 The first clamping assembly moves forward so that the top notch c111 of the second placement cavity c22 is directly connected to the first opening at the bottom of the clamping cavity. At this time, the first clamping assembly moves downward, so that the screw falls into the second placement cavity c22, and the screw rod part of the screw passes through the inner hole of the copper sheet, and the gasket overlaps the top surface of the copper sheet. The clamping cavity relaxes under the action of the outside world, and the first clamping assembly moves upward and disengages from the screw, thereby realizing the first transfer mechanism to transfer the first combination of the screw and the gasket in the first placement cavity c115 to the second placement cavity c22 and cooperate with the copper sheet.

[0082] For the first clamping component c32, if Figure 5 and Fig.10 As shown, it includes a mounting component c321, a first chuck c322, a second chuck c323 and two first elastic members (not shown in the figure). The mounting component c321 is fixed on the first lifting mechanism; the first chuck c322 and the second chuck c323 are vertically opposite and rotatable on the mounting component c321, a first elastic member is provided between the top of the first chuck c322 and the mounting component c321, and a first elastic member is provided between the top of the second chuck c323 and the mounting component c321. The two first elastic members respectively give a biasing force to the first chuck c322 and the second chuck toward the clamping cavity, so that in the absence of external force, the first chuck c322 and the second chuck c323 are close to each other to form a clamping cavity to clamp the gasket; when the outside world applies a force opposite to their respective biasing forces to the first chuck c322 and the second chuck c323, the first chuck c322 and the second chuck c323 move away from each other to release the clamping force on the gasket. In addition, as Fig.10 As shown, the mounting component c321 is also provided with a first baffle c324, and the first baffle c324 positions the clamping cavity at Figure 5 The opening on the left side of the middle is blocked, and the baffle c324 plays a limiting role in the first pushing mechanism pushing the gasket into the clamping cavity. As a variation, the first clamping assembly can also be a clamping cylinder or a manipulator.

[0083] The screw locking component c5 is an existing electric screwdriver, which is telescopically arranged on the first base c8 in a vertical direction corresponding to the top notch c111 of the second placement cavity c22 through a second lifting mechanism, and the electric screwdriver moves downward and extends into the top notch c111 of the second placement cavity c22 to tighten the screw. Alternatively, the screw locking component can also be other existing screw locking structures, such as other screwdrivers, and a rotating motor can be provided on the manual screw locking driver to ensure that the screwdriver rotates and locks.

[0084] like Figure 3 , Figure 4 and Figure 5 As shown, the mounting component c321 is provided with at least one clearance channel c325 in vertical direction and connected with the clamping cavity, and the bottom of the electric screwdriver can be extended into the clearance channel c325 one by one and connected with the clamping cavity. When the gasket is clamped in the clamping cavity, the electric screwdriver moves downward, and the electric screwdriver applies a downward force to the screw, so that the two clamps move away from each other, and the first clamping assembly moves upward, so that the first clamping assembly and the screw are completely separated, and the electric screwdriver rotates to tighten the screw, thereby realizing the locking of the screw and the copper sheet.

[0085] The first lifting mechanism and the second lifting mechanism have the same structure. For example, any lifting mechanism includes two first guide rails c311 extending vertically and arranged in parallel on the first base c8, and a second slider c312 slidably arranged on the first guide rails c311 driven by a first driver c313. The first driver c313 can be a second cylinder with a telescopic shaft extending vertically, and the first clamping assembly c32 or the electric screwdriver is driven to perform lifting and lowering movements through the telescopic movement of the second cylinder. Figure 4 As shown, optimally, the first lifting mechanism and the second lifting mechanism share the first guide rail c311, and the second slider c312 corresponding to the electric screwdriver is located above the second slider c312 corresponding to the first clamping assembly c32, so that the structures of the two lifting mechanisms are compact and occupy a small space. As a variation, the lifting mechanism can also be other structures, such as a meshing structure of a gear and a rack; or directly use the telescopic shaft of the telescopic cylinder to be fixedly connected to the first clamping assembly or the electric screwdriver.

[0086] like Figure 2As shown, it also includes a first discharge bin c71 fixedly mounted on the first base c8 and having a discharge channel that can communicate with at least one second placement cavity c22 along the first direction; and a second pushing mechanism c92 that is telescopically mounted on the first base c8 relative to the second placement cavity c22 along the first direction, and is used to push the workpiece in the second placement cavity c22 into the discharge channel. This second pushing mechanism extends into the second placement cavity c22 through the first opening c112 of the second placement cavity c22, and pushes the second combination of the screw and the copper sheet assembled in the second placement cavity c22 into the first discharge bin c71 through the second opening c113, so as to remove the workpiece on the second mold seat, so as to facilitate the reverse sliding and resetting of the second mold seat c2, so that the second placement cavity c22 and the second discharge port of the second material receiving mechanism are connected again, and the material receiving state is realized.

[0087] like Fig.11 As shown, it also includes a transition plate c6 arranged between the discharge channel and the second placement cavity c22; the transition plate c6 is provided with a transition placement cavity c61 which penetrates along the first direction and is connected with the second placement cavity c22 and the discharge channel, so that the second pushing device pushes the second combination assembled with the screws and the copper sheet into the transition placement cavity c61 first, and then pushes it into the discharge channel. The transition placement cavity c61 is optimally flush with the second placement cavity c22 in the horizontal direction, and the structure is the same as that of the second placement cavity.

[0088] The first pushing mechanism and the second pushing mechanism have the same structure. Fig. 9 As shown, the first pushing mechanism is located above the second pushing mechanism, and any pushing mechanism includes a pushing component and a second driver connected to the pushing component. The pushing component is driven by the second driver to perform telescopic movement toward or away from the first placement cavity c115 or the second placement cavity c22 corresponding to each other. The second driver can be a third cylinder whose telescopic axis extends along the first direction. For example, the pushing component includes a plate c911 connected to the second driver, and a pushing strip c912 provided on the side end of the plate c911 facing away from the second driver. There can be multiple pushing strips c912, and the pushing strips c912 correspond to the corresponding placement cavities one by one. Under the drive of the second driver, the pushing strips c912 can extend into or out of the corresponding placement cavities to realize the pushing action of the workpiece in the placement cavity. Optimally, the number of placement cavities corresponds to the number of pushing strips one by one.

[0089] like Figure 2 As shown, it also includes a first conveying mechanism arranged on the discharge port of the first discharge bin c71. For example, the first conveying mechanism is a second belt conveyor c72. A material unloading transition bin is provided at the front end of the second belt conveyor c72 to facilitate the transfer of the second assembly of screws and copper sheets assembled in the first discharge bin c71 to the material dividing device of the fourth station at any time.

[0090] A retractable receiving mechanism for receiving unqualified products is provided above the first conveying mechanism and below the discharge port of the first discharge bin c71. The receiving mechanism includes a receiving bin c73 and a fourth cylinder driving the receiving bin c73 to perform a retractable movement along the sliding direction of the first mold base c1. Correspondingly, a torque sensor for detecting the torque of the electric screwdriver is provided inside the above-mentioned electric screwdriver, and a controller electrically connected to the sensor, and the controller is electrically connected to the fourth cylinder. The controller controls the fourth cylinder to drive the receiving bin c73 to perform an extension or retraction movement according to the detection signal of the torque sensor.

[0091] When the torque sensor detects a torque less than the preset torque, it indicates that the screw and the copper sheet are not locked in place, and the product is unqualified; or the workpiece output from the first discharge bin c71 is only the copper sheet. At this time, the controller controls the fourth cylinder to extend, so that the receiving bin c73 extends below the discharge port and above the belt, thereby receiving the unqualified product into the receiving bin c73; if the detected torque is greater than or equal to the preset value, preferably equal to the preset value, it indicates that the screw and the copper sheet in the second placement cavity c22 are locked in place, and the controller drives the fourth cylinder to retract, so that the receiving bin c73 moves away from above the belt, and the assembly of the screw and copper sheet falling in the first discharge bin c71 falls directly on the belt and is transported to the material dividing device at the fourth station.

[0092] The screws and washers are pre-assembled to form a first assembly. The locking process of the locking device of the screws and the copper sheet in this embodiment is as follows:

[0093] First, the first feeding port of the first feeding mechanism ' and the second feeding port of the first feeding mechanism ' (at Figure 5 The first assembly and the copper sheet are respectively transported to the first placement cavity c115 and the second placement cavity c22; wherein the gasket in the first assembly overlaps the boss c114 of the first placement cavity c115, and the copper sheet overlaps the slot c21 in the second placement cavity c22, and during this process, both mold seats are in a material receiving state;

[0094] Next, the first mold seat slides toward the direction close to the second mold seat ( Figure 5 The blocking component c12 on the first mold base c1 slides against the first material discharge port, and the first clamping component c32 is driven by the first lifting mechanism to move up or down, so that the second opening c113 of the first placement cavity c115 slides until it is flush with and connected to the second opening of the clamping cavity of the first clamping component c32 in the horizontal direction. During this sliding process, the first mold base c1 is in a material blocking state;

[0095] After that, the first pushing mechanism performs an extension movement ( Figure 5The push strips c912 are inserted into the first placement cavity c115 through the first opening c112 one by one, and a thrust toward the clamping cavity is applied to the gasket. The first assembly is pushed into the clamping cavity through the second opening c113 and abuts against the baffle c324. The two clamps clamp the two ends of the gasket under the biasing force of the two first elastic members, and the first pushing mechanism retracts and resets ( Figure 5 The first mold base c1 slides in the opposite direction and returns to the starting position ( Figure 5 The first placement cavity c115 is connected to the first material discharge port again, so that the first placement cavity c115 is in a material receiving state again;

[0096] At the same time or afterwards, the second mold base c2 slides toward the direction close to the first mold base c1 ( Figure 5 The first clamping assembly c32 is driven by the first lifting mechanism to move downward, so that the top notch c111 of the second placement cavity c22 is directly connected with the first opening at the bottom of the clamping cavity, and the screw rod part of the screw is directly opposite to the inner hole of the copper sheet; the blocking component c12 on the second mold base c2 slides and abuts against the second material discharge port, and the second mold base c2 is in a material blocking state during this sliding process; the first clamping assembly c32 is driven by the first lifting mechanism to move downward again, so that the screw rod part extends into the inner hole of the copper sheet;

[0097] The second lifting mechanism drives the electric screwdriver to move downward, and the bottom of the electric screwdriver passes through the clearance channel c325 and extends into the clamping cavity, exerting a downward force on the screw, so that the two clamps move away from each other, releasing the clamping force on the gasket, and the first clamping assembly moves upward so that the first clamping assembly is completely separated from the first combination of the screw and the gasket. Under the rotation of the electric screwdriver, the first combination locks the screw on the copper sheet;

[0098] After that, the electric screwdriver moves upward, and the second pushing mechanism moves outward ( Figure 5 The push strips c912 thereon extend into the second placement chamber c22 through the first opening one by one, push the second assembly formed by the screws and the copper sheet locked together forward, and push it into the transition placement chamber c61 through the second opening, and then push it to the first discharge bin c71. The second assembly falls onto the second belt conveyor c72 through the first discharge bin c71, and is finally transported to the material dividing device on the fourth station;

[0099] Finally, the second pushing mechanism performs a retraction motion ( Figure 5 The push bar exits the second placement cavity c22 and returns to the starting position; the second mold seat c2 slides in the opposite direction ( Figure 5 The second mold base c22 is in a state of receiving the material, and the second mold base c2 is in a state of receiving the material. Similarly, the locking assembly of the next screw and the copper sheet is realized.

[0100] During the entire locking process, the feeding process of the screws and the copper sheet is realized by the first feeding mechanism ' and the first feeding mechanism ", and no manual feeding is required, so as to ensure that the screws and the copper sheet are placed in place in the first placement cavity c115 and the second placement cavity c22 respectively; and when the screws are transferred to the copper sheet, the first pushing mechanism is used to complete it, and under the lifting movement of the first clamping component, it is ensured that the screw part of the screw is directly inserted into the inner hole of the copper sheet, and then the electric screwdriver is used to automatically rotate to lock the screw and the copper sheet in place to form a second combination, and the second pushing mechanism pushes the locked second combination to the first discharge bin c71, and finally transports it to the next process via the belt conveyor, so that the locking device has high working efficiency and high yield rate after the screws and the copper sheet are locked.

[0101] As a first replaceable implementation of the above embodiment, the above first lifting mechanism and the second lifting mechanism can be independently arranged without sharing a guide rail. As a second replaceable implementation of the above embodiment, the horizontal projections of the first mold base and the second mold base can overlap but be staggered in height, and the horizontal projections of the first placement cavity and the second placement cavity can overlap. In this case, there is no need to set the above first pushing mechanism. The first transfer mechanism can use the first clamping assembly to directly clamp the workpiece in the first placement cavity and place it in the second placement cavity. In this case, the two clamps of the first clamping assembly can be extended into the first placement cavity to clamp the workpiece.

[0102] As a further variation, the horizontal or vertical positions of the first mold base and the second mold base are not limited, and can also be set on the first base without sliding. As long as the first transfer mechanism can move in three-dimensional space and has a clamping function, the workpiece in the first placement cavity can be transferred to the second placement cavity. For example, the first transfer mechanism includes a mechanical arm and a manipulator fixed on the mechanical arm. As a variation, the first placement cavity can only have a top notch, without the above-mentioned first and second openings. The first feeding mechanism directly transports screws and copper sheets to the first placement cavity and the second placement cavity from the top notch. For example, the first feeding mechanism is separately provided with a moving mechanism. After the workpiece is loaded, the moving mechanism drives the first feeding mechanism to move away to avoid the top notch, so as to facilitate the transfer or subsequent locking of the workpiece. Or, for example, the first feeding mechanism is a manipulator that can move in three dimensions. In addition, when the screw is not equipped with a gasket, when the screw is placed in the first placement cavity, the nut of the screw can abut on the above-mentioned abutment position.

[0103] For the material dividing device on the fourth station, if Figures 13 to 19 As shown, it includes a second base arranged on the fourth station of the base frame, a rotating body, a fifth cylinder b91, a material blocking component b92, and a fixed body.

[0104] Among them, Fig.13 and Fig.18 As shown, the fixed body is arranged on the second base and has an air cavity and at least one first inlet b211 and at least one air outlet channel b22 connected to the air cavity, and the outside world transports gas into the air cavity through the first inlet b211; the rotating body is provided with a vertical third feed port b121 and is horizontally rotatably arranged on the second base; the fifth cylinder b91 is installed on the rotating body; the blocking component b92 corresponds to at least one of the third feed port b121; the blocking component b92 is driven by the fifth cylinder b91 to slide back and forth toward or away from the respective corresponding third feed port b121 to block or open the respective corresponding third feed port b121; at least one third opening b31 is provided on the rotating body away from the third feed port b121 and is sealed and connected to the air inlet of the fifth cylinder b91 through the first air pipe; the air outlet channel b22 is distributed along the rotation path direction of at least one third opening b31, and the third opening b31 is connected to the corresponding air outlet channel b22 at any position on its rotation path.

[0105] When the rotating body rotates to switch the position of the third material discharge port on it to above the receiving mechanism at a different workstation, since the air outlet channel b22 is distributed along the rotation path direction of the third opening b31, the third opening b31 can always be connected with the air outlet channel during the rotation process, and the gas in the air cavity of the fixed body continuously transports gas to the first air pipe through the air outlet channel b22 and the third opening b31, and then continuously transports gas to the fifth cylinder; at the same time, the first air pipe rotates with the rotating body as a whole, and the fixed body is in a stationary state relative to the rotating body, so the air pipe that transports gas to the fifth cylinder will not be entangled, ensuring that the fixed body continuously transports a uniform amount of gas to the fifth cylinder, and the air pressure of the fifth cylinder driving the material blocking component to perform telescopic movement is stable, ensuring that the fifth cylinder drives the material blocking component to perform smooth telescopic movement, and the material blocking component can accurately block or open the third material discharge port, ultimately improving the accuracy of material distribution of the material distribution device. Preferably, if Fig.13 As shown, the rotating body includes a rotating seat b1 and a transition body b3 fixed on the rotating seat. The rotating seat b1 is horizontally rotatably arranged on the second base and has a vertical third feed opening b121, such as Fig.13 A third material discharge port b121 is provided on the left end of the rotating seat b1, and the right end is rotatably arranged on the second base.

[0106] For the structure of the rotating seat b1, Fig.14As shown, preferably, the rotating seat b1 includes a mounting section b11 and an operating section b12, wherein the mounting section b11 extends vertically and is provided with a vertically penetrating clearance channel inside; the operating section b12 is horizontally bent and fixed on the outer wall surface of the mounting section b11, and is provided with a third material discharge opening b121. For example, optimally, the operating section b12 is fixed on the top outer wall surface of the mounting section b11, and the third material discharge opening b121 is provided on one end of the operating section b12 away from the mounting section b11, or the third material discharge opening b121 can also be provided at other positions of the operating section b12 away from the mounting section b11.

[0107] In order to prevent the workpiece from sliding out from the top edge of the third feed opening b121, Fig.14 As shown, an annular baffle b13 is provided on the rotating seat b1 around the outer periphery of the top edge of the third material discharge port b121. The rotating seat b1 is rotatably arranged on the second base through the mounting section b11 sleeved on the lower part of the fixed body, the mounting section b11 is driven to rotate by the driving assembly, and the transition body is sleeved on the upper part of the fixed body and rotatably arranged on the second base as the rotating seat rotates.

[0108] like Fig.13 and Fig.14 As shown, the driving assembly includes a first rotating wheel b41, a second rotating wheel b42 and a transmission belt b43. The first rotating wheel b41 is sleeved outside the mounting section b11; the second rotating wheel b42 is driven by a rotating driver b44 and is horizontally rotatably arranged on the second base. For example, the rotating driver b44 is a rotating motor, the output shaft of which is fixed in the inner hole of the second rotating wheel b42, and the transmission belt b43 is a closed loop and sleeved on the outer peripheral wall of the first rotating wheel b41 and the second rotating wheel b42 in the horizontal direction, so that when the rotating motor rotates, the second rotating wheel b42 is driven to rotate, and then the first rotating wheel b41 is driven by the transmission belt b43 to rotate synchronously with the second rotating wheel b42, and finally the entire rotating seat b1 is driven to rotate on the second base, so that the rotating seat b1 is horizontally rotatably installed on the second base. For example, the first rotating wheel b41 and the second rotating wheel b42 are both gears, or both are synchronous wheels.

[0109] like Fig.13 and Fig.16 As shown, the transition body b3 is fixed on the top of the rotating seat b1, for example, the transition body b3 and the rotating seat are fixedly connected by a connecting component b32. Optionally, the connecting component includes a first plate and a second plate that are horizontally parallel, the second plate is located above the first plate, and a transition plate that vertically connects the first plate and the second plate at one end that is close to each other. Among them, the first plate is fixed on the action section b12 of the rotating seat b1, and the second plate is fixed on the top of the transition body b3.

[0110] A plurality of third openings b31 are provided on the transition body b3, at least one third opening corresponds to an air outlet channel b22, the transition body b3 is sleeved outside the upper part of the fixed body, and the rotating seat b1 is sleeved outside the lower part of the fixed body, so that the entire rotating body is rotatably provided on the second base by being sleeved outside the fixed body, and then the third opening b31 is rotatably provided on the outer periphery of the corresponding air outlet channel b22, so that when the transition body b3 rotates with the rotating seat, the third opening b31 rotates on the outer periphery of the air outlet channel b22, and the third opening b31 is always connected with the air outlet channel b22. For example, the air outlet channel b22 is provided on the outer wall surface of the upper part of the fixed body, and the third opening b31 is provided on the side wall of the transition body b3. Optionally, there are a plurality of third openings b31, and a plurality of third openings b31 can correspond to one air outlet channel b22; or one third opening b31 corresponds to a plurality of air outlet channels b22. Optimally, the third openings b31 correspond one to one to the air outlet channels b22.

[0111] like Fig.17 and Fig.18 As shown, the fixed body includes a first body b2 and a connecting tube b5 fixed on the bottom of the first body, and the above-mentioned air outlet channel b22 and the first inlet b211 are both arranged on the first body; the mounting section of the rotating seat is sleeved outside the connecting tube b5, and the transition body b3 is sleeved outside the top of the first body b2. For example, the air outlet channel b22 is an annular groove that is recessed from the outside to the inside on the outer wall surface of the first body b2, and annular protrusions b23 are formed on both sides of the annular groove; at least one first outlet b212 is arranged on the side wall of the first body b2, and the air outlet channel b22 is connected to the air cavity of the first body b2 through the at least one first outlet b212.

[0112] Preferably, the top of the first body b2 is an annular boss, the gas outlet channel b22 is arranged on the outer wall of the annular boss, and the first inlet b211 is arranged on the lower side wall of the first body b2. As for the gas cavity, the inner cavity of the first body b2 can be directly used as the gas cavity to store gas, or as Fig.19 As shown, the first outlet b212 corresponds one-to-one with the first inlet b211 and is connected through a first pipeline b24 provided in the inner cavity of the first body b2. At this time, the inner cavity of the first pipeline serves as an air cavity, and the external air supply mechanism directly transports gas to the first inlet b211 through the second air pipe.

[0113] Corresponding to the connecting tube b5, the connecting tube b5 is arranged in the clearance channel of the installation section, the top and bottom of the connecting tube b5 extend out of the clearance channel, the top of the connecting tube b5 is fixed on the bottom of the first body b2, and the bottom of the connecting tube b5 is fixed on the second base, so that the installation of the rotating seat, the transition body b3 and the fixed body on the second base is compact, and the space occupied by the material distribution device is small. Optimally, the inner cavity of the connecting tube b5 is a hollow structure.

[0114] For the second base, preferably, Fig.13 and Fig.14 As shown, the second base includes a bottom plate b63, a plurality of columns b61 vertically fixed on the bottom plate b63, and two third mounting plates b62 mounted on the columns b61 in a horizontal and parallel manner. The two third mounting plates b62 are suspended above the bottom plate b63 and a mounting area is formed between the two. When the above-mentioned drive assembly is installed on the second base, it is best that the rotating motor is installed on the third mounting plate b62 located below, and the first rotating wheel b41, the second rotating wheel b42 and the transmission belt b43 are arranged in the mounting area surrounded by the two third mounting plates b62. The third mounting plate b62 located above is provided with a fourth clearance hole b621, and the bottom of the mounting section b11 of the rotating seat b1 passes through the first clearance hole and is fixed in the inner hole of the first rotating wheel b41, and the top of the mounting section b11 extends upward; the bottom of the connecting cylinder b5 is fixed on the third mounting plate located below.

[0115] In addition, in order to strengthen the firmness of the installation section b11 on the second base, as Fig.15 As shown, a support seat b65 is sleeved outside the mounting section b11, the bottom of the support seat b65 is fixed on the third mounting plate b62 located above, and a bearing is arranged between the support seat b65 and the mounting section b11.

[0116] For the second base, in addition to the above-mentioned structure, it can also be any other structure, for example, only the above-mentioned third mounting plate b62 is provided, or other structures are provided, and the specific structure is not limited and can be determined according to actual needs. For the drive assembly, in addition to the above-mentioned structure, the drive assembly can also be other structures, such as a meshing structure of a rack and a gear, the driver drives the rack to slide back and forth linearly, the rack drives the gear to rotate, and the inner hole of the gear is sleeved outside the mounting section b11, which can also realize the horizontal rotation of the driving seat b1.

[0117] like Fig.13As shown, the fifth cylinder b91 is installed on the rotating seat b1, for example, it is installed on the bottom surface of the action section b12 of the rotating seat b1, but it needs to be set away from the third feed opening b121. One end of the blocking component b92 is fixed on the telescopic shaft of the fifth cylinder b91. The fifth cylinder b91 drives the blocking component b92 to slide back and forth toward or away from the respective corresponding third feed opening b121 to block or open the respective corresponding third feed opening b121. For example, when the fifth cylinder b91 drives the material blocking component b92 to make an extending movement towards the third material discharge port b121, the material blocking component b92 abuts against the bottom surface of the third material discharge port b121, thereby blocking the bottom of the third material discharge port b121 and preventing the workpiece in the third material discharge port b121 from falling. At this time, the third material discharge port b121 is in a non-discharging state, which is convenient for the rotating seat b1 to rotate to switch the position of the third material discharge port b121, and then transfer to the top of the receiving mechanism b7 at a different position; on the contrary, when the fifth cylinder b91 drives the material blocking component b92 to make a retracting movement away from the third material discharge port b121, the material blocking component b92 is removed from the bottom surface of the third material discharge port b121, and the third material discharge port b121 is in an open state. The workpiece can fall out of the third material discharge port b121, so that the third material discharge port b121 is in a discharging state.

[0118] In addition, the annular protrusion b23 corresponding to the first body b2 is made of conductive material, and a conductor (not shown in the figure) is provided on the inner wall surface of the side wall of the corresponding transition body b3, such as a carbon brush or a terminal. When the transition body b3 rotates with the rotating seat b1, the conductor forms a rotational contact with the outer periphery of the annular protrusion, thereby achieving electrical conduction between the conductor and the annular protrusion b23.

[0119] Correspondingly, the above-mentioned material distribution device also includes two limit switches (not shown in the figure) arranged at intervals on the action section, and the end of the telescopic shaft of the fifth cylinder is provided with a sensing plate, which is located between the two limit switches and can abut on the limit switch, so that the telescopic shaft can only do reciprocating telescopic movement between the two limit switches, and when the sensing plate abuts on any limit switch, the limit switch controls the fifth cylinder to stop the action, and limits the travel of the telescopic shaft driving the material blocking component. The two limit switches are electrically connected to the conductor through a first wire (not shown in the figure), which can be connected to the same conductor, or connected to a conductor respectively; the power supply is arranged on the second base, and is electrically connected to the annular protrusion of the first body b2 through a second wire, such as the wire extends into the inner cavity of the first body b2 and is connected to the inner wall surface of the annular protrusion, so that the power of the power supply is transmitted to the annular protrusion b23 through the second wire, and the annular protrusion b23 transmits the conductor in a rotating abutment manner, and the conductor is transmitted to the limit switch through the first wire, thereby realizing the power supply to the limit switch.

[0120] When the rotating body drives the fifth cylinder b91 and the limit switch to rotate, the conductor, the limit switch, the fifth cylinder b91 and the first wire rotate with the rotating seat, while the second wire, the power supply and the fixed body are all in a stationary state. Therefore, while the power supply supplies power to the limit switch, the first wire and the second wire will not be entangled, and the fifth cylinder is accurately positioned in its respective stroke, further ensuring the accuracy of the operation of the fifth cylinder driving the material blocking component, and the material blocking component more accurately blocks or opens the third feed port b121.

[0121] Optimally, as Fig.14 As shown, the material blocking component b92 is in an inverted L-shape, the horizontal portion of the inverted L-shape is used to block or open the third feed opening b121, and the vertical portion of the inverted L-shape is fixedly connected to the telescopic shaft of the fifth cylinder. At the same time, the vertical portion can serve as the above-mentioned induction plate and act with the two limit switches to achieve accurate limiting of the stroke of the fifth cylinder.

[0122] like Fig.13 and Fig.14 As shown, the material distribution device also includes a placement rack b64 arranged on the second base and located directly below the third material discharge port b121, and a photoelectric sensor b82 is arranged on the placement rack b64, and the photoelectric sensor b82 detects whether a material receiving box b81 is placed on the placement rack b64. If the material receiving box b81 is detected, the sensor sends the signal to the controller, and the controller controls the fifth cylinder b91 to retract. The electrical connection between the controller and the fifth cylinder is also achieved through the above-mentioned annular protrusion to prevent the connection wire from being entangled, and the material blocking component b92 is driven to move away from the third material discharge port b121, and the workpiece in the third material discharge port b121 directly falls into the material receiving box b81, and the unnecessary workpiece is recycled and reused. If the workpiece needs to be distributed to the material receiving mechanism b7, the material receiving box b81 is not arranged on the placement rack b64.

[0123] like Fig. 20 As shown, at least two second conveying mechanisms f2 are arranged below the rotation path of the third unloading port of the material dividing device. For example, four second conveying mechanisms f2 are arranged at intervals on the same circumference below the rotation path of the third unloading port b121. The structure of any second conveying mechanism is the same as that of the first loading mechanism of the locking device, including the first vibration bin c41, the first feeding channel c42 and the first conveying track c44, so as to realize the conveying of the classified terminals to the detection devices of the corresponding fifth stations. For example, there are two sets of detection devices, each set of detection devices corresponds to two second conveying mechanisms respectively, and each set of detection devices can detect the terminals in the two second conveying mechanisms separately at one time.

[0124] The material distribution process of the material distribution device in this embodiment is as follows:

[0125] If, in the initial state, the rotating seat b1 is directly above the first material receiving mechanism b7 at the first position, the material blocking component b92 is moved away from the third material discharge port b121, and the workpiece in the third material discharge port b121 continuously falls down onto the first material receiving mechanism b7; when the workpiece in the third material discharge port b121 needs to be discharged to the second material receiving mechanism b7 at the second position, at this time, the fifth cylinder b91 drives the material blocking component b92 to extend, and the material blocking component b92 blocks the bottom surface of the third material discharge port b121, blocking the third material discharge port b121, and the fifth cylinder b91 stops moving;

[0126] Afterwards, the rotating motor drives the second rotating wheel b42 to rotate, and in turn drives the first rotating wheel b41 and the rotating seat b1 to rotate, so that the rotating seat b1 rotates from above the first material receiving mechanism b7 to above the second material receiving mechanism b7 at the second position, so that the third material discharge port b121 is located directly above the second material receiving mechanism b7. At this time, the rotating motor stops, and the rotating seat b1 is switched from one station to another station.

[0127] During the entire rotation process of the rotating seat b1, the connecting tube b5 and the first body b2 are both in a stationary state on the second base, and the transition body b3, the first air pipe, the fifth air cylinder b91 and the material blocking component b92 rotate synchronously with the rotating seat b1. The third opening b31 on the transition body b3 is always rotationally connected with the air outlet channel b22, and the air cavity of the fixed body continuously transports gas to the first air pipe through the air outlet channel, and then transports a uniform amount of gas to the fifth air cylinder b91. Since the first air pipe rotates independently of the fixed body, the first air pipe will not be entangled, and the air pressure of the fifth air cylinder driving the material blocking component to perform telescopic movement is stable, ensuring that the fifth cylinder drives the material blocking component to perform smooth telescopic movement. The material blocking component can accurately block or open the third unloading port, and ultimately improve the accuracy of material distribution of the material distribution device;

[0128] Afterwards, the fifth cylinder b91 is started again, and the fifth cylinder b91 drives the blocking component b92 to retract, and the blocking component b92 is moved away from the third material discharge port b121, and the third material discharge port b121 is opened. At this time, the workpiece in the third material discharge port b121 falls on the second material receiving mechanism b7, and so on, so that the material dividing device can divide the different workpieces in the third material discharge port b121 into the material receiving mechanism b7 at the corresponding workstation of the workpiece, thereby realizing the function of precise material dividing.

[0129] As a modified implementation of the above embodiment, the rotating seat may also include only an action section, and the above-mentioned clearance channel is provided on one end of the action section away from the third material discharge port, and the clearance channel of the action section is sleeved outside the connecting tube b5. Or, the above-mentioned connecting tube b5 is not provided in the fixed body, and only the first body b2 is provided, and the top of the first body b2 passes through the clearance channel and is fixed on the second base.

[0130] As a further variation, the transition body b3 is mounted outside the fixed body, but the rotating seat may not be mounted outside the fixed body. In this case, the driving assembly directly drives the transition body b3 to rotate to drive the rotating seat to rotate, and also enables the third opening b31 to be rotatably arranged on the outer periphery of the corresponding air outlet channel b22 to maintain the connection between the third opening b31 and the air outlet channel b22.

[0131] Alternatively, the transition body b3 and the rotating seat are not mounted on the fixed body, and the rotating seat is arranged on the second base and outside the fixed body. When the rotating seat rotates, it drives the transition body b3 to roll around the air outlet channel b22 on the outer wall of the first body b2, and can also make the third opening b31 always in a connected state with the air outlet channel b22 during the rotation process.

[0132] Alternatively, the transition body b3 and the rotating seat are not sleeved on the fixed body, the rotating seat is arranged on the second base and outside the fixed body, and the transition body b3 is stacked on the top or bottom of the first body b2. In this case, the air outlet channel b22 is arranged on the top or bottom of the first body b2. In this case, the air outlet channel b22 may not be an annular groove, for example, it may be an annular opening or an opening of any shape. As long as the rotating seat drives the transition body b3 to rotate, the third opening b31 on the transition body b3 abuts against the air outlet channel b22 and rotates, so that the third opening b31 and the air outlet channel b22 remain in a connected state. In other words, the air outlet channel b22 is distributed along the rotation path direction of the third opening b31, and any position of the third opening b31 on its rotation path is in communication with the air outlet channel b22, which can avoid the first air pipe from being entangled.

[0133] For the detection device, Figure 21 to Figure 27 As shown, it includes a first carrier e1, a first plane reflector e2, a second plane reflector e3 and a visual detection system e4. Fig.21As shown, the first carrier e1 is a rectangular plate, and the first carrier e1 is provided with a first installation cavity e11 which is recessed inwards for embedding the first plane reflector e2 and the second plane reflector e3. In this embodiment, the first plane reflector e2 and the second plane reflector e3 have the same size, that is, the length, width, thickness and reflection surface area are the same. The first plane reflector e2 and the second plane reflector e3 are arranged on two opposite side walls of the first installation cavity e11, and the angle formed between the reflection surfaces of the first plane reflector e2 and the second plane reflector e3 is a poor angle. In order to be able to collect a clearer and more accurate reflection image, in this embodiment, the reflection surfaces of the first plane reflector e2 and the second plane reflector e3 are arranged at a right angle. This allows the two side surfaces of the corresponding plane reflector of the part to be detected located on the midline of the angle to present images of approximately the same clarity, and the images on both sides can be basically consistent with the entity of the part to be detected, which is convenient for distinguishing and detecting. The first plane reflector e2 , the second plane reflector e3 , the other two side walls of the first installation cavity e11 , and the bottom surface of the first installation cavity e11 together form a detection area with an isosceles trapezoidal cross section.

[0134] like Fig.21 As shown, a fixing portion is also provided on the first carrier e1 to fix the component to be detected. In the present embodiment, the fixing portion is a second mounting cavity that is recessed on the first carrier and connected to the first mounting cavity e11. Of course, the fixing portion can also be a clamping component provided on the surface of the first carrier e1, and the clamping component clamps and fixes the component to be detected and extends the part to be detected on the component to be detected into the detection area of ​​the first mounting cavity e11. The second mounting cavity is a mounting groove e12, and a connecting hole is provided on one side groove wall of the mounting groove e12, which is connected to the detection area in the first mounting cavity e11 through the connecting hole. In the present embodiment, two mounting grooves e12 are provided for each first mounting cavity e11, and the two mounting grooves e12 are symmetrically distributed on both sides of the first plane reflector e2 and the second plane reflector e3 in the first mounting cavity e11. As another example Fig.21 As shown, a positioning groove e121 whose groove shape matches the shape of the component to be detected is also provided in the installation groove e12. Fig. 22 As shown, the component to be tested is embedded and fixed in the positioning groove e121 and its part to be tested extends into the testing area through the connecting hole. A clamping space is reserved between the two ends of the positioning groove e121 and the two ends corresponding to the installation groove e12, so that the component can be clamped out by the clamp after passing the test.

[0135] like Fig.23As shown, a detection switch e9 is provided at the bottom of each positioning groove e121. In the present embodiment, the detection switch e9 is a photoelectric position detection switch, which is penetrated through the bottom of the positioning groove e121 and faces the inner cavity of the positioning groove e121. The photoelectric position detection switch detects the distance that the component to be detected (i.e., the terminal) enters the positioning groove e121 to determine whether the component to be detected enters the set position in the positioning groove e121, so that the detected part of any component to be detected is always located at the same detection position in the detection area, thereby improving the detection accuracy.

[0136] In this embodiment, Fig.21 As shown, each first carrier e1 is provided with two first installation cavities e11 symmetrically on the left and right and four installation grooves e12 corresponding to the two first installation cavities e11 respectively. The positioning groove e121 in each installation groove e12 can select a matching groove type according to different shapes of the components to be detected or different placement and fixing positions of the same components to be detected, such as Fig.21 and Fig.24 As shown, the two first carriers e1 are provided with positioning grooves e121 of different groove types, depending on specific needs.

[0137] like Fig.25 As shown, the visual inspection system e4 includes a camera module e41, a lens e42 and a light source e43. The lens e42 is circular. The shooting center axis of the camera module e41 is coaxially arranged with the lens e42. The light source e43 is distributed around the inner circumference of the lens e42. In this embodiment, two visual inspection systems e4 are arranged. The two visual inspection systems e4 correspond one-to-one to the two inspection areas on the same first carrier e1. The two visual inspection systems e4 are fixed on the third base e5 through a connecting plate.

[0138] like Fig.25 and Fig.26 As shown, a translation assembly e8, a lifting assembly e6 and a rotation assembly e7 are arranged between the visual inspection system e4 and the third base e5. Fig.26 As shown, the rotating assembly e7 includes a rotating arm and a rotating shaft e73. In this embodiment, the rotating arm is a first mounting plate e71 and a second mounting plate e72. The first mounting plate e71 is fixed on the third slider e631 of the lifting assembly e6. The second mounting plate e72 is rotatably arranged on the first mounting plate e71 via the rotating shaft e73. The visual inspection system e4 is fixed on the second mounting plate e72 via a connecting plate. A circle of evenly distributed positioning holes e711 is provided on the first mounting plate e71 around the rotating shaft e73. Symmetrical matching waist holes e721 are provided on the second mounting plate e72 at the circumferential positions of the positioning holes e711 around the rotating shaft e73. Fig.26As shown, four matching waist holes e721 are provided. After the visual inspection system e4 is rotated to a suitable angle, fasteners are passed through the matching waist holes e721 and their corresponding positioning holes e711 in sequence to lock the visual inspection system e4 in a suitable position. The fasteners are commonly used fasteners, such as screws and nuts.

[0139] like Fig.25 As shown, the lifting assembly e6 includes a lifting drive and a lifting guide assembly e63. The lifting guide assembly e63 includes a third slider e631 and a third guide rail e632. Two third guide rails e632 are provided, extending in the vertical direction and arranged in parallel on the fourth slider e821 of the translation assembly e8. The third slider e631 is slidably arranged on the two third guide rails e632. In this embodiment, the lifting drive adopts a handle e61 and a first worm gear e62. The handle e61 is rotatably arranged above the fourth slider e821. The first worm gear e62 is vertically arranged and located between the two third guide rails e632. One end of the first worm gear e62 is rotatably arranged on the third slider e631, and the other end is fixed on the handle e61. When the handle e61 rotates, it is suitable for driving the third slider e631 to perform lifting motion on the third guide rail e632 through the first worm gear e62, and at the same time drives the visual inspection system e4 arranged on the third slider e631 to perform lifting motion in the vertical direction.

[0140] like Fig.26 As shown, the translation assembly e8 includes a translation driver and a translation guide assembly e82. The translation guide assembly e82 includes a fourth slider e821 and a fourth guide rail e822. The fourth guide rail e822 is horizontally mounted on the third bases e5 on both sides. The fourth slider e821 is slidably set on the fourth guide rail e822. In this embodiment, the translation driver adopts a first drive motor e81. The driving end of the first drive motor e81 is connected to the second worm gear (not shown in the figure). The second worm gear is set on the third base e5 parallel to the extension direction of the fourth guide rail e822, and the second worm gear is rotatably matched on the fourth slider e821. Driven by the first drive motor e81, ​​the lifting assembly e6, the rotating assembly e7 and the visual detection system e4 are suitable for moving in the horizontal direction.

[0141] like Fig. 27As shown, in this embodiment, two ends of the first carrier e1 are respectively fixed on the first ring seat e102 and the second ring seat e103, the first ring seat e102 and the second ring seat e103 are coaxially fixed on the driving shaft of the second rotating motor e101, and both ends of the driving shaft are mounted on the detection platform e100, so that the first ring seat e102 and the second ring seat e103 are suspended, and under the drive of the second rotating motor e101, the first carrier e1 makes a circular motion with the first ring seat e102 and the second ring seat e103; that is, the first carrier is rotatably provided on the base frame, and the positioning groove has a material receiving state of docking and connecting with the unloading port of the second conveying mechanism when it is rotated to the first position, and a material discharging state of connecting with the clamping device when it is rotated to the second position.

[0142] For example, the first carrier e1 rotates with the ring seat, so that the notch of the positioning groove of the fixed part is in the horizontal direction and faces the first position of the unloading port of the second conveying mechanism, the unloading port of the second conveying mechanism just docks and connects with the notch of the positioning groove, and the terminal slides down directly from the second conveying mechanism into the positioning groove; then the first carrier continues to rotate a certain angle, such as 45 degrees, to detect the terminal in the positioning groove. During this process, the first ring seat and the second ring seat just block the unloading port of the second conveying mechanism respectively, and no longer continue to convey the terminal; when the terminal is qualified after the inspection, the ring seat continues to rotate so that the notch of the positioning groove faces the second position upward, such as rotating another 45 degrees, so that the clamping device clamps the terminal vertically downward to complete the terminal inspection; if the terminal inspection fails, the ring seat continues to rotate so that the notch of the positioning groove faces downward and docks with the top opening of the second discharge bin in the recovery area, and the unqualified terminal will fall into the second discharge bin and be discharged as an unqualified product; then, the first carrier e1 rotates one circle and is aligned with the second conveying mechanism again to receive the next batch of components to be inspected.

[0143] like Fig. 27 As shown, two first carriers e1 are provided, and the two first carriers e1 are arranged in parallel on one side of the visual inspection system e4. The positioning groove e121 on any first carrier e1 corresponds to the second conveying mechanism f2 of the component to be inspected. The component to be inspected is conveyed to the corresponding positioning groove e121 by the second conveying mechanism f2, and is driven by the second rotating motor e101 to rotate the first carrier e1 loaded with the component to be inspected to the optimal shooting inspection position.

[0144] For example, the first carrier e1 rotates to a position at an angle of 45° to the horizontal plane. The visual inspection system e4 is mounted above the second conveying mechanism f2 through the third base e5. Through the adjustment of the translation component e8, the lifting component e6 and the rotating component e7, the lens e42 covers the opening of the angle formed by the first plane reflector e2 and the second plane reflector e3, ensuring that the images reflected by the first plane reflector e2 and the second plane reflector e3 all fall within the shooting range of the camera module e41, and the first plane reflector e2 and the second plane reflector e3 are symmetrically distributed on both sides of the axis of the lens e42 to form an optimal shooting angle. The first imaging channel and the second imaging channel are respectively formed between the camera module e41 and the reflecting surfaces of the first plane reflector e2 and the second plane reflector e3. Image channel, the camera module e41 can selectively take the image of the part to be inspected reflected by the first plane reflector e2 through the first imaging channel and compare it with the standard images in the visual inspection system e4 library, or take the image of the part to be inspected reflected by the second plane reflector e3 through the second imaging channel and compare it with the standard images in the visual inspection system e4 library, or simultaneously take images of two angles reflected by the first plane reflector e2 and the second plane reflector e3 and compare them with the standard images of corresponding angles in the library, and use one visual inspection system e4 to realize the simultaneous acquisition and comparison of images of two different angles of the part to be inspected, thereby ensuring the inspection accuracy and reducing the inspection cost.

[0145] The detection process of the detection device in this embodiment is as follows: Fig. 27 For example, the first carrier e1 on the left is detected first, and the first carrier e1 on the right is detected later;

[0146] The left side component to be inspected (the terminal on the left side) enters the positioning groove e121 corresponding to the left side first carrier e1 through the horizontally arranged second conveying mechanism. The second rotating motor e101 drives the first carrier e1 on this side to rotate to a position at a 45° angle to the horizontal plane and stops. Through the adjustment of the translation component e8, the lifting component e6 and the rotating component e7, the visual inspection system e4 is made to shoot and compare the two inspection areas on the first carrier e1 one by one. When the inspection is qualified, the second rotating motor e101 drives the first carrier e1 to rotate to a vertical position facing upwards, and the qualified terminal is clamped out of the positioning groove by the clamping device. If the inspection is unqualified, the second rotating motor e101 drives the first carrier e1 to rotate to a vertical position facing downwards, so that the component automatically falls into the second discharge bin in the recycling area. After the first carrier e1 rotates one circle, it is aligned with the second conveying mechanism again to receive the next batch of components to be inspected.

[0147] After the inspection of the components on the first carrier e1 on the left is completed, the translation component e8 drives the visual inspection system e4 to translate to the right to capture the image of the component to be inspected on the first carrier e1 on the right for comparison. The first carriers e1 on the left and right sides are loaded with the components to be inspected in turn by the second rotating motor e101 and rotated to the shooting position. The visual inspection system e4 then translates back and forth between the two first carriers e1 to switch shooting.

[0148] As an alternative implementation, the first plane reflector e2 and the second plane reflector e3 may be replaced by reflective prisms.

[0149] Clamping device, such as Figures 29 to 36 As shown, it includes a second clamping assembly d1, a third transfer mechanism, a pressing assembly and a second transfer mechanism. Fig.29 As shown, the second clamping assembly d1 is driven by the third transfer mechanism and is at least vertically movable on the fourth base d6; the pressing assembly is driven by the second transfer mechanism and is at least vertically movable on the fourth base d6. The third transfer mechanism and the second transfer mechanism are the same common transfer mechanism. That is, the same transfer mechanism is used to drive the second clamping assembly d1 and the pressing assembly to perform synchronous vertical lifting and lowering movements. Fig.30 As shown, a transition component d31 is provided on the bottom of the transfer mechanism, and the tops of the second clamping assembly d1 and the top pressing assembly are both fixed on the transition component d31. For example, the transition component d31 includes two horizontally opposite and vertically extending plates.

[0150] like Fig.30 As shown, the second clamping assembly d1 has a third clamp d11 and a fourth clamp d12 arranged horizontally opposite to each other, and a driving assembly that drives the third clamp d11 and the fourth clamp d12 to switch between a clamping state close to each other and a loose state away from each other, for example, the driving assembly is a second clamping cylinder d14, and the third clamp d11 and the fourth clamp d12 are respectively fixed on the two clamping ends of the second clamping cylinder d14. Under the movement of the second clamping cylinder d14, the third clamp d11 and the fourth clamp d12 are driven to approach each other or to move away from each other, so that the two clamps clamp the parts to be clamped, such as terminals, or release the clamping force on the terminals. Optionally, as Fig.30 As shown, the third clamping head d11 has two first clamping parts arranged at intervals and a mounting part d13 fixing the tops of the two first clamping parts, and the third clamping head d11 is in an arch shape with an opening facing downward; similarly, the fourth clamping head d12 has two second clamping parts arranged at intervals and a mounting part d13 fixing the tops of the two second clamping parts, and the fourth clamping head d12 is in an arch shape with an opening facing downward. The first clamping part corresponds to the second clamping part one by one, and the bottom of the second clamping part is provided with a notch recessed upward, and the notch is used for the component to be clamped to be embedded.

[0151] When the second clamping component d1 clamps the terminal, the first clamping part abuts against the outer wall end face of the screw nut, and the notch of the second clamping part is sleeved on the circular column on the copper sheet or can be directly sleeved on the outer wall surface of the part of the screw rod extending out of the copper sheet, and the inner wall surface of the second clamping part abuts against the outer wall end face of the copper sheet, and the copper sheet is located between the gasket and the second clamping part, so that with the cooperation of the first clamping part and the second clamping part, a clamping force is applied to the outer surface of the screw nut and the copper sheet, thereby achieving a firm clamping effect on the terminal.

[0152] Since the third clamp d11 has two first clamping parts and the fourth clamp d12 has two second clamping parts, the second clamping assembly d1 can clamp two terminal structures at one time, which is convenient for simultaneously conveying and assembling the two terminals in the terminal installation cavity of the base, so as to improve the assembly efficiency of the terminal and the base. As a variation, the first clamping part of the third clamp d11 can also be one, three, four or more, and correspondingly, the second clamping part of the fourth clamp d12 can be one, three, four, etc., as long as the first clamping part corresponds to the second clamping part one by one, and the specific number of settings can be determined according to actual needs.

[0153] As a simple variation, the first clamping part is provided with the above-mentioned notch at the bottom, and the second clamping part is not provided with the above-mentioned notch. In the clamping process, the notch of the first clamping part is sleeved on the outside of the screw nut or the outside of the gasket, and the inner wall surface of the first clamping part abuts against the outer wall surface of the copper sheet, and the second clamping part can abut against the end surface of the screw rod. Alternatively, the first clamping part and the second clamping part are both provided with the above-mentioned notch, or neither of them is provided with the above-mentioned notch.

[0154] like Fig.31 and Fig.32 As shown, the pressing assembly includes a pressing member d22, a second elastic member (not shown in the figure) and a mounting body d21. The second elastic member can be a spring, and the top of the mounting body d21 is fixed to the bottom of the two transition components d31, so that the two transition components d31 and the mounting body d21 form a U-shape with an open top. In the above-mentioned second clamping assembly d1, the second clamping cylinder d14 is fixed to the two transition components d31 and is located in the U-shaped inner cavity, and the two clamping ends of the second clamping cylinder d14 are respectively located outside the two sides of the mounting body d21. Optimally, Fig.30In the embodiment, two transition parts d31 are located at the left and right ends of the mounting body d21, and two clamping ends are located at the front and rear sides of the mounting body d21, so that the pressing assembly is arranged between the third clamp d11 and the fourth clamp d12. The mounting body d21 is provided with a hollow cavity d211 extending vertically, the top of the pressing part d22 is slidably arranged in the hollow cavity d211, and the bottom thereof extends out of the hollow cavity d211, and the second elastic part is arranged between the top inner wall surface of the mounting body d21 and the top of the pressing part d22, and the second elastic part applies a downward biasing force to the pressing part d22. For example, the longitudinal cross-sectional shape of the mounting body d21 is T-shaped, the horizontal part of the T-shaped is fixed on the transition part d31, and the vertical part of the T-shaped is provided with a hollow cavity d211.

[0155] The bottom of the pressing member d22 has a horizontal pressing surface d221. The second elastic member applies a downward biasing force to the pressing member. In the initial state, the pressing member is subject to the biasing force of the second elastic member and the pressing surface d221 is located below the bottom end surface of any chuck.

[0156] When the clamping device assembles the terminal on the base, the third clamp d11 and the fourth clamp d12 first clamp the terminal; then, the same transfer mechanism drives the second clamping component d1 and the pressing component to move downward as a whole, and the second elastic member is in an initial compressed state at this time; since the pressing surface of the pressing member is located below any one of the clamps, the pressing surface first abuts against the surface of the base (avoiding the terminal mounting cavity); when the transfer mechanism continues to move downward, the pressing member no longer continues to move downward, and the second elastic member is compressed downward by the mounting body d21, thereby increasing the clamping force of the pressing surface on the base, and the third clamp and the fourth clamp of the second clamping assembly move downward and extend into the terminal mounting cavity, placing the terminal in the terminal mounting cavity, and moving away from each other. During this process, the pressing surface always presses on the base, and even if the third clamp and the fourth clamp collide with the wall of the terminal mounting cavity, the base remains in a stationary state due to the clamping force of the pressing surface.

[0157] Afterwards, the transfer mechanism drives the second clamping component d1 and the top pressing component to move upward as a whole. Due to the setting of the second elastic member, when the second clamping component d1 moves upward with the transfer mechanism first, the top pressing member d22 does not move upward first, but the second elastic member is gradually released from the compression amount until the clamp exits the terminal installation cavity upward. Then the second elastic member is in the initial compression state, or in a state where the compression amount is greater than the initial compression amount. At this time, the top pressing member d22 is still kept tightly pressed on the base to ensure that the two clamps will not cause the base to move horizontally or shake during the extension of the two clamps from the hollow cavity d211. Afterwards, as the transfer mechanism continues to move upward, the second clamping component d1 continues to move upward above the hollow cavity d211, and when the second elastic member is released to the initial compression amount, the second elastic member is no longer released. At this time, the second elastic member, the mounting body d21 and the top pressing member d22 move upward as a whole, and the top pressing member d22 gradually separates from the base in the vertical direction, thereby completing the installation process of the terminal on the base.

[0158] There are many ways to slide the top of the pressing member d22 in the hollow cavity d211, for example: Fig.33 As shown, the pressing member d22 includes a second body extending vertically and a flange d222 fixed on the top of the second body and protruding horizontally, and the top of the pressing member d22 is hooked in the hollow cavity d211 through the flange d222 and slidably arranged on the mounting body d21. Optionally, the body is cylindrical.

[0159] In order to guide the vertical sliding of the pressing piece d22, the pressing assembly also includes a guide body d23 fixed on the bottom of the mounting body d21. The guide body d23 is provided with a guide hole extending vertically. The bottom of the pressing piece d22 passes through the mounting body d21 and the guide hole in sequence and extends outward. The guide hole guides the vertical lifting and lowering movement of the pressing piece d22, further ensuring that when the pressing surface d221 of the pressing piece d22 abuts against the base, the clamping force generated on the base is vertical and has no component force in the horizontal direction, thereby ensuring that the base will not move or shake horizontally during the installation of the terminal on the base.

[0160] The same transfer mechanism drives the second clamping assembly d1 and the pressing assembly to perform vertical lifting and horizontal movement, such as Fig.34 , Fig.35 and Fig.36As shown, the transfer mechanism includes a guide channel, a rolling member d42 and a linkage component d41. The guide channel is a groove that is horizontally recessed from the outside to the inside on one side surface of the fourth base d6. The guide channel includes two vertically extending first channels d81 and a horizontally extending second channel d82. The second channel d82 connects the tops of the two first channels d81, thereby forming a U-shaped channel with an opening facing downward on the fourth base d6 as a whole. The rolling member d42 is rotatably arranged in the guide channel, and a connecting shaft d43 is fixed to the inner hole of the rolling member d42, and the connecting shaft d43 extends outward. For example, the rolling member d42 is a roller. The linkage component d41 has a horizontally extending long hole. One end of the linkage component d41 is driven by a driver and is rotatably disposed on the fourth base d6, and the other end is sleeved on the connecting shaft d43 through the long hole. The driver can be selected as a rotating motor. The rotating motor rotates to drive the linkage component d41 to rotate and then drives the rolling element d42 to roll in the guide channel; the above-mentioned transition component d31 is fixed on the connecting shaft d43 and is located on the outside of the linkage component d41.

[0161] For example, rolling element d42 is initially at Fig.34 At the bottom of the first channel d81 on the left side, as the rotating motor rotates clockwise and drives the linkage component d41 to swing clockwise, the linkage component d41 drives the rolling element d42 to roll upward from the bottom of the first channel d81, so that the rolling element d42 drives the second clamping component d1 and the top pressing component to move upward, and then when the rolling element d42 rolls in the second channel d82, the rolling element d42 drives the second clamping component d1 and the top pressing component to move horizontally, and then the rolling element d42 Fig.34 The rolling element d42 rolls downward in the first channel d81 on the right side, so that the rolling element d42 drives the second clamping assembly d1 and the pressing assembly to move downward, thereby synchronously driving the second clamping assembly d1 and the pressing assembly to move upward, move horizontally and move downward in sequence; conversely, when the rotating motor rotates counterclockwise, the rolling element d42 first moves upward in the first channel d81 on the right side, moves horizontally in the second channel d82, and moves downward in the first channel d81 on the left side.

[0162] By adopting the guide channel, the lifting and lowering motion and horizontal movement stroke of the rolling element d42 can be accurately positioned and limited. When the clamping device clamps different terminals of the same batch, the transfer stroke of each terminal remains consistent, ensuring that each terminal is installed in place on the base.

[0163] Optionally, the connecting shaft d43 is connected to the transition assembly via a sliding mechanism, such as Fig.35 and Fig.36As shown, the sliding mechanism includes a fixed component d47, two fifth guide rails d44, two fifth sliders d45 and two sixth guide rails d46. The fixed component d47 is sleeved on the connecting shaft d43, and the linkage component d41 is located between the fixed component d47 and the rolling element d42; the two fifth guide rails d44 extend vertically and are fixed on the fixed component d47; the two fifth sliders d45 are respectively provided with two first slide grooves for the fifth guide rails d44 to be embedded one by one and extend vertically; the two sixth guide rails d46 extend horizontally and are fixed on the fourth base d6 and are located on the upper and lower sides of the second channel d82; the fifth slider d45 can be slidably arranged on the sixth guide rail d46 in a one-to-one correspondence, and the side surface of the fifth slider d45 facing the sixth guide rail d46 is provided with a second slide groove suitable for sleeved on the sixth guide rail d46; the above-mentioned transition component d31 is fixed on the bottom of the fifth guide rail d44.

[0164] In this transfer structure, when the rolling member d42 moves upward from the bottom of the first channel d81 on the left, the fifth guide rail d44 and the fixed component slide upward in the first slide groove synchronously with the rolling member d42; thereafter, when the rolling member d42 rolls horizontally in the second channel d82, the fifth guide rail d44 and the fixed component are stationary relative to the fifth slider d45, and the fifth slider d45 drives the fifth guide rail d44 and the fixed component to slide horizontally on the sixth guide rail d46; thereafter, when the rolling member d42 rolls downward in the first channel d81 on the right, the fifth slider d45 stops sliding, and the fifth guide rail d44 slides downward in the first slide groove of the fifth slider d45.

[0165] The setting of the sliding mechanism makes it convenient for the fifth guide rail d44 to cooperate vertically with the first slide groove when the rolling member d42 rolls in the guide channel, thereby further guiding and limiting the lifting and lowering movement of the transition component d31; the fifth slider d45 and the sixth guide rail d46 to cooperate horizontally, thereby further guiding and limiting the horizontal movement of the transition component d31, corresponding to the rolling of the rolling member d42 in the first channel d81, the transition component d31 only performs lifting and lowering movement in the vertical direction; and corresponding to the rolling of the rolling member d42 in the second channel d82, the transition component d31 only performs horizontal movement, thereby ensuring that the transfer stroke of the clamping device for different terminals remains consistent, and ensuring that each terminal is installed in place on the base.

[0166] In addition, if Fig.30 As shown, the third lifting mechanism d5 is also included, which is disposed between the third transfer mechanism or the second transfer mechanism and the transition component d31 and can be lifted and lowered vertically. For example, a connecting plate d32 is disposed at the bottom of the fifth guide rail d44, and a third lifting mechanism d5 is fixed between the transition component d31 and the connecting plate d32. The third lifting mechanism d5 can be a lifting cylinder, or other lifting structures, such as a meshing structure of a gear and a rack, and the rotation of the gear drives the rack to perform a lifting movement in the vertical direction.

[0167] The third lifting mechanism d5 is set up, when the terminal is assembled on the current base and the previous base has not been moved away, the clamping device clamps the terminal on the next base in place and moves downward in the first channel d81 to prevent the terminal on the clamping device from hitting the terminal assembled on the previous base. At this time, the third lifting mechanism d5 set up separately will be started to drive the second clamping assembly d1 and the pressing assembly to move upward, so that the terminal on the second clamping assembly d1 is staggered in height with the terminal on the previous base. After the previous base is moved away, it moves downward to assemble the terminal on the next base.

[0168] The use process of the clamping device of this structure is as follows:

[0169] by Fig.34 For example, if the previous process places the terminal below the second channel d82 on the right; in the initial state, the rolling element d42 of the sliding mechanism is located at the bottom of the first channel d81 on the right, and the terminal installation cavity on the base is located below the first channel d81 on the left. The terminal on the lower right side needs to be transferred and assembled in the terminal installation cavity on the lower left side through the above-mentioned clamping device;

[0170] First, the third clamp d11 and the fourth clamp d12 of the second clamp assembly d1 clamp the two terminals;

[0171] Afterwards, the rolling element d42 of the transfer mechanism rolls upward in the first channel d81 on the right, and the fifth guide rail d44 brings the transition component d31, the second clamping assembly d1 and the top pressing assembly to move upward vertically as a whole;

[0172] Secondly, the rolling member d42 rolls horizontally from the right to the left in the second channel d82, and the fifth slider d45 drives the fifth guide rail d44, the transition component d31, the second clamping assembly d1, and the top pressing assembly to slide from the right to the left on the sixth guide rail d46, so that the terminal is transferred from the first channel d81 on the right to the top of the first channel d81 on the left;

[0173] Afterwards, the rolling element d42 rolls downward in the first channel d81 on the left, and the fifth guide rail d44 brings the transition component d31, the second clamping assembly d1 and the top pressing assembly to move downward vertically as a whole. The downward movement process includes the following steps:

[0174] (1) First, the second clamping assembly d1 and the pressing assembly move downward as a whole, and the second elastic member is still in the initial compression state until the pressing surface d221 of the pressing member d22 abuts against the surface of the base;

[0175] (2) When the pressure piece d22 continues to move downward, it stops moving upward, and the second clamping assembly d1 continues to move downward, and the second elastic piece is further compressed until the second clamping assembly d1 places the terminal in the terminal installation cavity below.

[0176] (3) The third clamp d11 and the fourth clamp d12 move away from each other, and the pressing member d22 is still pressed tightly against the base;

[0177] After that: the rolling element d42 of the transfer mechanism moves upward in the first channel d81, so that the chuck extends upward from the hollow cavity d211, and the compression amount of the second elastic element is gradually released accordingly. At this time, the pressing element d22 is still pressed on the base and does not move upward;

[0178] Then, the rolling member d42 continues to move upward in the first channel d81, and the second elastic member is released to the initial compressed state. At this time, the top pressing member d22 moves upward along with the transfer mechanism and separates from the base, and the rolling member d42 moves to the top of the first channel d81;

[0179] Afterwards, the rolling element d42 moves horizontally to the right in the second channel d82, driving the second clamping assembly d1 and the pressing assembly to move right as a whole;

[0180] Finally, the rolling element d42 moves downward in the first channel d81 on the right side, driving the second clamping assembly d1 and the pressing assembly to move downward as a whole, so that the second clamping assembly d1 and the pressing assembly are in the starting state;

[0181] By analogy, the clamping device transfers the next terminal and assembles it in the hollow cavity d211 on the next base.

[0182] As a further variation, the same transfer mechanism can drive the second clamping assembly and the pressing assembly to perform only lifting movements without horizontal movements; the terminals of the previous process can be fed by a robot, and the two clamps of the second clamping assembly clamp the terminals above the base, and then the robot moves away from the lifting path of the transfer mechanism for lifting movements.

[0183] As a modified embodiment, the second clamping assembly and the pressing assembly may not be driven by the same transfer mechanism, but may be driven by the third transfer mechanism and the second transfer mechanism to perform lifting and horizontal movement. In this case, the pressing assembly may or may not be provided with a second elastic member.

[0184] When the terminal is installed on the base, the third clamp and the fourth clamp first clamp the terminal, and then the third transfer mechanism drives the second clamping assembly to move downward toward the base; at the same time, the second transfer mechanism drives the pressing assembly to move downward toward the base, and before the second clamping assembly is embedded in the terminal installation cavity, the pressing surface of the pressing assembly is abutted against the base to apply a downward pressing force to the base; then, the third clamp and the fourth clamp are embedded in the terminal installation cavity, and the terminal is installed in the terminal installation cavity. The third clamp and the fourth clamp are relaxed, so that the pressing assembly always applies a downward pressing force to the base to ensure that the base does not shake or move horizontally; then, the second clamping assembly is driven by the third transfer mechanism to make an upward rising movement, so that the third clamp and the fourth clamp first withdraw from the terminal installation cavity, and the pressing surface is still pressed on the base at this time; then, the pressing assembly is driven by the second transfer mechanism to make an upward rising movement again and separate from the base, so that during the installation of the clamped component on the base, the base always remains stationary and will not affect the assembly accuracy of subsequent parts on the base.

[0185] As a further variation, the third transfer mechanism and the second transfer mechanism can also respectively drive the second clamping assembly and the pressing assembly to perform lifting movements only without horizontal movements; the terminal of the previous process can be fed by the robot, and the two clamps of the second clamping assembly clamp the terminal above the base, and then the robot moves away from the lifting path of the transfer mechanism. For the third transfer mechanism and the second transfer mechanism, it can also be an existing lifting structure, such as a lifting cylinder, or a meshing structure of a rack and a gear, and the gear rotates to drive the rack to perform lifting movements.

[0186] For the second feeding mechanism of the feeding device, if Figures 37 to 42 As shown, it includes a fifth base a8, two sets of feeding mechanisms, a support platform a4, a fourth lifting mechanism a2 and a fourth transfer mechanism a5. Fig.40 As shown, a plurality of workstations are arranged horizontally and sequentially on the support table a4. Fig.42 As shown, each set of feeding mechanisms is arranged on the fifth base a8 and has a discharge port, the two sets of feeding mechanisms are arranged horizontally and spaced apart, and the discharge ports of the two sets of feeding mechanisms are spaced apart by a third distance; the fourth transfer mechanism a5 is arranged on the fifth base a8 and is used to drive the support table a4 to move so that any workstation can be connected to the discharge port; the fourth lifting mechanism a2 is used to drive the support table a4 to do lifting and lowering movements, and when the support table a4 moves with the fourth transfer mechanism, the side wall of the support table facing the discharge port can be slidably blocked on the discharge port to switch between a blocking state and a non-blocking state where the discharge port is removed.

[0187] For example, Fig.37 , Fig.38 , Fig.39 , Fig.40 and Fig.41As shown, there are four workstations, namely the first workstation 'a411, the second workstation 'a412, the third workstation 'a413 and the fourth workstation 'a414. The four workstations are arranged in a straight line on the support table a4. The first workstation 'a411 and the third workstation 'a413 are separated by a first distance, and the second workstation 'a412 and the fourth workstation 'a414 are separated by a second distance. The first distance, the second spacing and the third distance are equal. Under the moving action of the fourth transfer mechanism a5, the two sets of feeders are The discharge ports of the two feeding mechanisms are respectively connected to the first station 'a411 and the third station 'a413, so that the first station 'a411 and the third station 'a413 are used to receive the same batch of workpieces; or the discharge ports of the two feeding mechanisms are respectively connected to the second station 'a412 and the fourth station 'a414, so that the second station 'a412 and the fourth station 'a414 are used to receive the same batch of workpieces, but the first station 'a411 and the second station 'a412 receive different batches of workpieces. For ease of description, the workpiece received by the first station 'a411 is described as the first workpiece, the workpiece received by the second station 'a412 is described as the second workpiece, and the discharge ports of the two feeding mechanisms are respectively described as the first discharge port ( Fig.42 The discharge port on the front side) and the second discharge port ( Fig.42 The outlet on the middle and rear side).

[0188] like Fig.37 and Fig.40 As shown, the support table a4 is provided with a U-shaped second baffle a42 at the position corresponding to each workstation, and the opening of the second baffle a42 is close to one side of the discharge port of the feeding mechanism, and can be connected with and communicated with the discharge port of the feeding mechanism. The workpiece sliding out of the discharge port of the feeding mechanism slides into the workstation surrounded by the second baffle a42 through the opening of the second baffle a42, and the second baffle a42 plays a limiting role on the workpieces sliding down on their respective workstations.

[0189] As for the structure of the feeding mechanism, preferably, Fig.42 As shown, each set of feeding mechanism is similar in structure to the first feeding mechanism in the locking device, and includes a second vibration bin a11, a second feeding channel a12 and a feeding component. Among them, the second vibration bin a11 is driven by the vibrator to vibrate, and the second vibration bin a11 has a placement inner cavity; the starting end of the second feeding channel a12 is fixed on the outer wall surface of the placement inner cavity, and is spirally wound outside the placement inner cavity and extends downwardly to the end of the second feeding channel a12, and the end of the second feeding channel a12 serves as a discharge port; the feeding component is used to feed the placement inner cavity of the second vibration bin a11. When the vibrator drives the second vibration bin a11 to vibrate, the workpiece in the second vibration bin a11 will be vibrated, and vibrated from the placement inner cavity to the spiral second feeding channel a12, and fall to the corresponding workstation through the discharge port, thereby realizing the feeding process.

[0190] Alternatively, if Fig.42 As shown, the feeding component is a first belt conveyor a14, and a feeding bin a15 installed on a fifth base a8 is provided at the rear end of the belt, the bottom of the feeding bin a15 is close to or in sliding contact with the belt surface, and the bottom opening is connected to the conveying surface of the belt, and a lowering bin a16 is provided at the front end of the belt, and the lowering port of the lowering bin a16 is located directly above the top opening of the second vibration bin a11. When it is necessary to continuously feed the second vibration bin a11, the outside world continuously drops the workpieces onto the belt through the feeding bin a15, and the belt continuously moves forward, continuously conveying the workpieces thereon to the lowering bin a16, and the workpieces continuously drop into the placement cavity of the second vibration bin a11 through the lowering port of the lowering bin a16.

[0191] In addition, a feeding guide rail a13 corresponding to and connected to the corresponding feeding outlet can be provided on the feeding outlet of the feeding mechanism, so that the feeding outlet can convey the workpiece through the feeding guide rail a13. For the convenience of description, the two feeding guide rails a13 are respectively described as the first feeding guide rail a13 and the second feeding guide rail a13, each feeding guide rail includes a guide rail bottom surface and stoppers provided on both sides of the guide rail bottom surface, and a top notch is formed between the two blocks. The feeding guide rail can be arranged tilted downward or horizontally.

[0192] like Fig.37 , Figure 3 and Fig.40 As shown, the fourth lifting mechanism a2 is fixed on the top of the slidable driving plate a31 on the fourth transfer mechanism a5, and one end of the driving plate a31 close to the discharge port extends out of the fourth transfer mechanism a5, and the support platform a4 is fixed on the fourth lifting mechanism a2. The fourth transfer mechanism a5 drives the fourth lifting mechanism a2 and the support platform a4 to slide back and forth through the sliding of the driving plate a31, and the direction of the reciprocating linear sliding is from the first station 'a411 to the second station 'a412 or from the second station 'a412 to the first station 'a411, thereby changing the position of each station on the fifth base a8. Optionally, the fourth lifting mechanism a2 is a lifting cylinder, and the top of the vertical telescopic axis of the lifting cylinder is fixed to the support platform a4.

[0193] In order to make the support platform a4 perform linear lifting motion in the vertical direction, the loading device also includes at least one guiding mechanism for guiding the support platform a4 to perform linear lifting motion.

[0194] For example, Fig.40As shown, there are two guide mechanisms, which are distributed on both sides of the lifting cylinder. The guide mechanism includes a guide component a21 and a movable component a22, wherein the bottom of the guide component a21 is fixed on the driving plate a31, and it has a guide channel extending vertically and having a first opening at the top; the movable component a22 is fixed on the bottom of the support platform a4 and is suitable for being able to extend into the guide channel vertically. When the lifting cylinder drives the support platform a4 to perform lifting movement, the support platform a4 drives the movable component a22 to perform a linear lifting movement in the guide channel, thereby guiding the lifting movement of the support platform a4. For example, the movable component a22 is a cylindrical guide column, and the corresponding guide component a21 is a cylindrical hollow cylinder.

[0195] Optimally, as Fig.41 As shown, a first clearance hole a311 corresponding to the guide mechanism is provided at the position where the driving plate a31 extends out of the fourth transfer mechanism a5, and a mounting outer edge is provided on the lower periphery of the guide component a21, and the mounting outer edge overlaps and is fixed on the top of the driving plate a31. The guide channel of the guide component a21 passes through in the vertical direction, and the lower part of the guide component a21 extends into the first clearance hole a311, so that when the movable component a22 moves downward with the support platform a4, the bottom of the movable component a22 can pass through the first clearance hole a311 and extend downward, thereby increasing the stroke of the lifting and lowering movement of the support platform a4.

[0196] For the fourth transfer mechanism a5, if Figure 3 As shown, the fourth transfer mechanism a5 includes a driving assembly arranged on the fifth base a8, a slider driven by the driving assembly to slide linearly, and the above-mentioned driving plate a31. The driving plate a31 is fixed on the top of the slider. The driving assembly includes a second driver a51, a screw rod a52 driven to rotate by the second driver a51, and a slider fitted on the screw rod a52 and sliding along the axial direction of the screw rod a52 as the screw rod a52 rotates. Optionally, the second driver a51 is a rotating motor, and the driving assembly forms a screw structure. The above-mentioned driving plate a31 is fixedly connected to the slider, and when the slider slides back and forth, it can drive the driving plate a31 to slide back and forth linearly.

[0197] For example, Fig.41 As shown, a third fixed plate a54 fixed on the fifth base a8 is also provided between the screw rod a52 and the driving plate a31, and the slider is located below the third fixed plate a54. The slider is fixedly connected to the driving plate a31 by setting a fourth mounting plate a53, and an avoidance groove is provided on the top of the fourth mounting plate a53, and the third fixed plate a54 is embedded in the avoidance groove. The top of the fourth mounting plate is fixed on the driving plate a31, so that the fourth mounting plate a53 slides on the third fixed plate a54 with the slider, and the third fixed plate a54 guides the sliding of the fourth mounting plate a53.

[0198] In addition, if Fig.40 and Fig.41 As shown, at least one second clearance hole a43 is provided at a position corresponding to any workstation on the support table a4, for example, a second clearance hole a43 is provided in each workstation. The above-mentioned switchable feeding device also includes a vacuum adsorption mechanism installed on the driving plate a31. The vacuum adsorption mechanism has a suction cup a6 that can be correspondingly inserted into the second clearance hole a43, and a vacuum pumping device connected to the suction cup a6. For example, the vacuum pumping device is a vacuum pump, and the top adsorption surface of the suction cup a6 is flush with the placement plane of the respective workstation.

[0199] Of course, the suction cup a6 can be replaced by a suction nozzle. A third clearance hole can also be set at the location of the workstation, and an optical fiber sensor is set in the third clearance hole to detect whether there is a workpiece on the workstation, and a controller electrically connected to the optical fiber sensor controls the opening or closing of the vacuum pump according to the signal of the optical fiber sensor.

[0200] When the workpiece slides onto the workstation, the optical fiber sensor detects that the workpiece has slipped onto the workstation and sends a signal to the controller. The controller then controls the vacuum pump to turn on, forming a negative pressure environment at the adsorption surface of the suction cup a6, generating adsorption force on the bottom of the workpiece to prevent the workpiece from sliding or shaking on the workstation, and ensuring that the position of the workpiece on its respective workstation remains unchanged when the support table a4 moves with the fourth transfer mechanism a5. When the workpiece on the workstation needs to be removed later, the controller controls the vacuum pump to turn off, the adsorption force of the suction cup a6 on the workpiece disappears, and the workpiece can be removed.

[0201] like Fig.37 As shown, the switchable loading device further includes a third material receiving bin a7 fixedly arranged relative to the fifth base a8 and located below the support platform a4. The top of the third material receiving bin a7 has a second opening, which is located directly below the discharge port. When the support platform a4 is driven by the fourth transfer mechanism a5 to avoid the discharge port when the material is not blocked, the third material receiving bin a7 is used to receive the workpiece falling from the discharge port.

[0202] If, when the first work station 'a411 and the third work station 'a413 no longer need the first workpiece, the support table a4 moves away from the discharge port along with the fourth transfer mechanism a5. Fig.37The middle support table a4 and the drive plate a31 are moved from the front to the back as a whole, and the drive plate a31 and the support table a4 are moved as a whole away from the discharge port. At this time, although the first workpiece is no longer added to the second vibration bin a11 of the feeding mechanism, a small amount of the first workpiece is sometimes left in the feeding guide a13 in the feeding mechanism, and these small amounts of first workpieces are directly dropped into the discharge bin for recycling. Similarly, when the second station 'a412 and the fourth station 'a414 no longer need the second workpiece, similarly, the support table a4 and the drive plate a31 are removed, and all the second workpieces remaining on the feeding mechanism are dropped into the third receiving bin a7 through the feeding guide a13 for recycling and reuse. Optionally, the number of the third receiving bin a7 corresponds to the discharge port one by one and is located directly below the discharge port.

[0203] The loading process of the switchable loading device of this embodiment is as follows:

[0204] When the first workpiece needs to be transported to the first station 'a411' and the third station 'a413', the position of the support table a4 is changed under the drive of the fourth transfer mechanism a5, for example Fig.37 Move forward, so that the first station 'a411 and the third station 'a413 are respectively connected with and connected to the outlets of the first feed guide rail and the second feed guide rail, the support table a4 is in a non-blocking state, and the fourth lifting mechanism does not work; turn on the feeding mechanism, and the outlets of the first feed guide rail and the second feed guide rail of the feeding mechanism transport the first workpiece to the first station 'a411 and the third station 'a413 respectively; when the two first workpieces slide onto the first station 'a411 and the third station 'a413 respectively, the optical fiber sensor detects the first workpiece on the station and gives a signal to the controller, and the controller controls the vacuum pump to start according to the signal, so that the adsorption surface of the suction cup a6 forms a negative pressure, and the first workpiece is adsorbed on their respective stations.

[0205] At this time, the fourth transfer mechanism a5 drives the support platform a4 to move away from the discharge port, for example Fig.37 The support table a4 moves backward and moves to the next process, and the material-picking mechanism takes away the first workpiece; then the fourth transfer mechanism a5 drives the support table a4 to move forward, so that the first station 'a411 and the third station 'a413 are respectively connected to the outlets of the first feed guide rail and the second feed guide rail, and the next first workpiece just starts to slide onto the first station 'a411 and the third station 'a413, and so on, and the first workpiece will be continuously transported to the first station 'a411 and the third station 'a413.

[0206] Alternatively, the lifting cylinder drives the support platform a4 to move upward as a whole, so that the side wall surface of the support platform a4 facing the outlet of the first feeding guide rail and the second feeding guide rail is blocked on the outlet of the first feeding guide rail and the second feeding guide rail; then the fourth transfer mechanism a5 drives the support platform a4 to move away from the discharge port, for example Fig.37 The support table a4 moves backward and moves to the next process, and the material-picking mechanism takes away the first workpiece; then the fourth transfer mechanism a5 drives the support table a4 to move forward again. In the process of the fourth transfer mechanism driving the support table to move, the side wall surface of the support table is always slidably blocked on the outlets of the first feed guide rail and the second feed guide rail; then the fourth lifting mechanism makes a descending movement, so that the first station ' and the third station ' are reset to the starting positions which are connected to the outlets of the first feed guide rail and the second feed guide rail respectively, and the first workpiece is received again, and so on, the first workpiece will be continuously transported to the first station 'a411 and the third station 'a413.

[0207] After the first workpiece is conveyed, the workstation needs to be switched, and two feeding mechanisms are required to convey the second workpiece to the second workstation 'a412 and the fourth workstation 'a414 respectively. At this time, the lifting cylinder drives the support table a4 to move upward as a whole, so that the side wall surface of the support table a4 facing the first feed guide rail and the second feed guide rail blocks the outlet of the first feed guide rail and the second feed guide rail, so that no workpiece will slide out of the outlet of the first feed guide rail and the second feed guide rail, so that the support table a4 is in a material blocking state; it prevents the second workpiece from scattering on the support table a4, or sliding on the first workstation 'a411 and the third workstation 'a413; at the same time, the fourth transfer mechanism a5 drives the support table a4 to move forward ( Fig.37 In the front of the first feeding guide rail), the second station 'a412 and the fourth station 'a414 slide to the top of the exit of the first feeding guide rail and the second feeding guide rail. When the support table slides with the fourth transfer mechanism, the side wall of the support table a4 can be slidably blocked on the exit of the first feeding guide rail and the second feeding guide rail, and the support table a4 is still in the material blocking state; then, the fourth lifting mechanism a2 is started, and the fourth lifting mechanism a2 drives the support table a4 to move downward, so that the second station 'a412 and the fourth station 'a414 descend and are respectively connected to the first feeding guide rail. The guide rail and the outlet of the second feed guide rail are connected, the support table a4 is in a non-blocking state, and the fourth lifting mechanism a2 stops working; the outlets of the first feed guide rail and the second feed guide rail can respectively transport the second workpiece to the second workstation 'a412 and the fourth workstation 'a414, and the conveying process of the second workpiece is the same as the conveying process of the first workpiece, so that during the switching process of different workstations, no workpieces will fall out of the outlets of the first feed guide rail and the second feed guide rail, and there will be no confusion caused by the same workstation receiving workpieces of different batches.

[0208] Thus, different batches of bases are conveyed into the second carrier on the third conveying mechanism through the second feeding mechanism, and then the third conveying mechanism drives the second carrier to be conveyed from the third station to the first station, and then the above-mentioned clamping device is used to install the terminal in the terminal installation cavity of the base.

[0209] In addition, if Figure 1 As shown, a sixth station is also provided on the base frame, and the sixth station is located between the third station and the first station. When the third conveying mechanism conveys the second carrier from the first station, the third conveying mechanism first conveys the second carrier to the sixth station. Since the second carrier h1 is at the third station, the small plane h2 in the switch is vertically placed on the second carrier. The flip mechanism g is located on the base frame at the sixth station and above the third conveying mechanism. The flip mechanism g is a flip clamping cylinder. The flip clamping cylinder first performs a lifting movement to clamp the small plane h2, and then performs a horizontal rotation to place the small plane horizontally on the second carrier, so as to facilitate the subsequent process of loading the small plane h2 into the base h3 in a horizontal state; after that, the third conveying mechanism conveys the second carrier to the first station. The third conveying mechanism can be optionally a belt conveyor, or other conveying mechanisms.

[0210] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
