In addition, 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.

[0065] Example 1

[0066] This embodiment provides a locking device, such as Figures 1 to 10 As shown, it includes a first mold base c1, a second mold base, a transfer mechanism, two feeding mechanisms c4 and a plurality of screw locking components c5.

[0067] like Figure 5 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 base c8 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 6 and Figure 7 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.

[0068] like Figure 6 and Figure 7 As shown, the structures of the first placement cavity c115 and the second placement cavity c22 are similar. 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 ( Figure 8 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 ( Figure 8 middle right port) and the second port c113 ( Figure 8 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.

[0069] like Figure 7 As shown, the second placement cavity c22 replaces the horizontal boss c114 of the first placement cavity c115 with a horizontally 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 also be the same as that of the second placement cavity, and the structure of the second placement cavity can also be the structure of the first placement cavity, except that the slot is provided. In the process of screwing the screw, the slot plays a role in positioning the copper sheet.

[0070] Two feeding mechanisms c4 are arranged on the 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 feeding mechanisms c4 are respectively described as the first feeding mechanism c4 and the second feeding mechanism c4. The first feeding port of the first feeding mechanism c4 is connected with and communicated with the first opening c112 of the first placement cavity c115. The screw slides downward through the first feeding port and slides into the first placement cavity c115 through the first opening c112, thereby conveying the assembly of the screw and the gasket into the first placement cavity c115. The second feeding port of the second feeding mechanism c4 is connected with and communicated with the first opening c112 of the second placement cavity c22. The copper sheet slides downward through the second feeding port and slides into the second placement cavity c22 through the first opening c112, thereby conveying the copper sheet into the second placement cavity c22.

[0071] As for the structure of the feeding mechanism c4, it can be any existing conveying mechanism or feeding structure, preferably, as Fig.11 As shown, the feeding mechanism c4 includes a vibration bin c41 that is driven by a vibrator c43 to vibrate, and the vibration bin c41 has a placement cavity; the starting end is arranged on the outer wall surface of the placement cavity, and a feeding channel c42 is spirally arranged outside the placement cavity and inclined downward, and the end of the feeding channel c42 serves as a discharge port. The first combination of screws and gaskets or copper sheets falls into the feeding channel c42 due to the vibration of the vibration bin c41, and slides downward in the feeding channel c42, thereby realizing the delivery of screws or copper sheets to the corresponding placement cavities. Of course, a conveying track c44 can also be provided at the discharge port, and the outlet of the conveying track c44 serves as the final discharge port. As a variation, the feeding mechanism can also be other structures, such as a conveyor, an existing feeder and other structures, as long as the corresponding screws and copper sheets can be placed in the first placement cavity and the second placement cavity respectively.

[0072] 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 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 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 loading mechanism c4 will transport the workpiece into the corresponding placement cavity again.

[0073] For example, Figure 6 As 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 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 and blocks the corresponding discharge port.

[0074] Optimally, as Figure 8 As shown, the first mold seat c1 is located at Figure 8 The second mold seat c2 is located at the front side of Figure 8 The first feeding mechanism c4 and the second feeding mechanism c4 are respectively arranged on the right side of the first mold base c1 and the second mold base c2 and avoid the transfer mechanism. Assuming the starting position, the first unloading port and the second unloading port are respectively Figure 8 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.

[0075] After the first combination of the screw and the gasket is placed in the first placement cavity c115, the first placement cavity c115 is Figure 8 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 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 transfer mechanism, the first mold base c115 is in a material blocking state. Figure 8 The first mold base is in a state of receiving materials. Optionally, the blocking component c12 is in the form of a plate.

[0076] like Figure 4 As shown, the drive assembly includes a track c231 fixed on the 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 telescopic cylinder is 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 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 4 The right and left sides of the fixing plate c81 of the middle base c8 facilitate the transfer mechanism and the locking screw component c5 to be arranged on Figure 4 The right side of the middle fixing plate c81 makes it convenient to lock the copper sheet and screws on the right side.

[0077] The transfer mechanism is arranged on the base c8 and can reciprocate between the first placement cavity c115 and the second placement cavity and perform telescopic movement along the top notch of the second placement cavity. Figure 1 ,picture, Figure 3 and Figure 4 As shown, the transfer mechanism includes a first lifting mechanism c31, a clamping assembly c32 and a first pushing mechanism c91. In this embodiment, through the movement of the two mold seats and the cooperation of the first pushing mechanism, the transfer mechanism is reciprocated between the first placement cavity and the second placement cavity relative to the base, so as to transfer the screw in the first placement cavity to the top of the copper sheet in the second placement cavity; and then the first lifting mechanism is used to make the transfer mechanism perform telescopic movement or lifting and lowering to install the screw rod part of the screw into the inner hole of the sheet.

[0078] The first lifting mechanism c31 is fixed on the base c8; the 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 4 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 4 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. 9 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 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.

[0079] When the transfer mechanism needs to transfer the screws in the first placement cavity c115 to the second placement cavity c22, the first mold seat c1 is first Figure 4 The first mold base c1 slides backward and the clamping assembly c32 moves up or down, so that the first placement cavity c115 of the first mold base c1 is in the first direction ( Figure 4 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 ( Figure 4 Then, the second mold seat c2 is in the state of receiving the material; Figure 4 The clamping assembly slides 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 clamping assembly moves downward, causing the screw to fall into the second placement cavity c22, and the screw rod portion 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 clamping assembly moves upward and disengages from the screw, thereby realizing the 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.

[0080] For the clamping component c32, if Figure 4 and Fig. 9 As shown, it includes a mounting component c321, a first chuck c322, a second chuck c323 and two 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, an elastic member is provided between the top of the first chuck c322 and the mounting component c321, and an elastic member is provided between the top of the second chuck c323 and the mounting component c321, and the two elastic members respectively give the first chuck c322 and the second chuck a biasing force 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. 9 As shown, the mounting component c321 is also provided with a baffle c324, which places the clamping cavity at Figure 4The 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 deformation of the clamping assembly, the clamping assembly can also be replaced by other clamping mechanisms, such as a clamping cylinder or a manipulator.

[0081] The screw locking component c5 is an existing electric screwdriver, which is telescopically arranged on the base c8 in the 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.

[0082] like Figure 2 , Figure 3 and Figure 4 As shown, the mounting component c321 is vertically provided with at least one clearance channel c325 communicating with the clamping cavity, and the bottom of the electric screwdriver can be extended into the clearance channel c325 one by one and communicate with the clamping cavity.

[0083] 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 screw and the gasket fall downward out of the clamping cavity to fall into the second placement cavity c22. The clamping assembly moves upward, so that the clamping assembly and the screw are completely separated, and the electric screwdriver rotates to tighten the screw, thereby locking the screw and the copper sheet; or the clamping assembly relaxes the clamping cavity under other external forces, and the clamping assembly moves upward to separate from the screw; thereafter, the electric screwdriver moves downward to directly apply rotational torque to the screw, thereby locking the screw and the copper sheet.

[0084] 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 base c8, and a second slider c312 slidably arranged on the first guide rails c311 driven by a first driver c313. The first driver can be a cylinder with a telescopic shaft extending vertically, and the clamping assembly c32 or the electric screwdriver is driven to perform lifting and lowering movements through the telescopic movement of the cylinder.

[0085] like Figure 3As 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 clamping assembly c32, so that the structures of the two lifting mechanisms are compact and the space occupied is small. As a variation, in addition to the above-mentioned slider and guide rail structure, the lifting mechanism can also be other lifting structures in the prior art, such as a gear and rack meshing structure, a rotating motor drives the gear to rotate, and then drives the rack to do lifting and lowering movement; or directly use the telescopic shaft of the telescopic cylinder to be fixedly connected with the clamping assembly or the electric screwdriver.

[0086] like Figure 1 As shown, it also includes a discharge bin c71 fixed on the 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 arranged on the base c8 relative to the second placement cavity c22 along the first direction, which 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 discharge bin c71 through the second opening c113 to remove the workpiece on the second mold seat, so that the second mold seat c2 can slide back and reset, so that the second placement cavity c22 and the second discharge port of the second material receiving mechanism can be docked and connected again to achieve the material receiving state.

[0087] like Fig.10 As shown, it also includes a transition plate c6 arranged between the discharge channel and the second placement chamber c22; the transition plate c6 is provided with a transition placement chamber c61 which penetrates along the first direction and is connected to the second placement chamber c22 and the discharge channel, so that the second pushing device pushes the second assembly assembled with the screws and the copper sheet into the transition placement chamber c61 first, and then pushes it into the discharge channel. The transition placement chamber c61 is preferably flush with the second placement chamber c22 in the horizontal direction, and the structure is the same as that of the second placement chamber. As a variation, of course, the transition plate may not be provided, and the inlet of the discharge bin may be directly connected to the second port of the second placement chamber. Or as a further variation, the discharge bin may not be provided, and the screws and copper sheets assembled in the second placement chamber may be directly used as the feed port for the next process.

[0088] The first pushing mechanism and the second pushing mechanism have the same structure. Figure 8 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, and 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 cylinder whose telescopic shaft extends along the first direction.

[0089] The pushing component is in the form of a plate, for example, it 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 respective placement cavities one by one. Under the drive of the second driver, the pushing strips c912 can extend into or withdraw from the respective corresponding placement cavities to achieve the pushing action of the workpiece in the placement cavity. For example, when there are two first placement cavities c115, there are two corresponding pushing strips c912 on the first pushing mechanism. When there are two second placement cavities c22, there are also two corresponding pushing strips c912 on the second pushing mechanism. As a variation, in addition to the above-mentioned structure, the pushing mechanism can also be other structures, such as the pushing mechanism is a telescopic cylinder, and the telescopic shaft of the cylinder directly extends into the corresponding placement cavity to push the corresponding workpiece.

[0090] In addition, if Figure 1 As shown, it also includes a conveying mechanism arranged at the discharge port of the discharge bin c71, such as a belt conveyor c72, and a material unloading transition bin is arranged at the front end of the belt conveyor c72, so as to facilitate the transfer of the second assembly assembled with screws and copper sheets in the discharge bin c71 to the next process at any time. As a variation, the conveying mechanism can be other existing conveying mechanisms in addition to the belt conveyor.

[0091] A retractable receiving mechanism for receiving unqualified products is provided above the conveying mechanism and below the discharge port of the discharge bin c71. The receiving mechanism includes a receiving bin c73 and a first cylinder for driving the receiving bin c73 to perform a retractable movement along the sliding direction of the first mold seat c1. Correspondingly, a torque sensor for detecting the torque of the electric screwdriver is provided inside the electric screwdriver, and a controller electrically connected to the sensor is electrically connected to the first cylinder. The controller controls the first cylinder to drive the receiving bin c73 to perform an extension or retraction movement according to the detection signal of the torque sensor.

[0092] When the torque sensor detects that the torque is 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 discharge bin c71 is only the copper sheet, not the assembly of the screw and the copper sheet. At this time, the controller controls the first 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 can drive the first cylinder to retract so that the receiving bin c73 is moved away from above the belt, and the assembly of the screw and the copper sheet falling from the discharge bin c71 directly falls on the belt and is transported away. Alternatively, as a variation, the above-mentioned conveying mechanism and receiving mechanism may not be provided, and the workpiece falling from the discharge port of the discharge bin is directly used as the feed port of the next process.

[0093] 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:

[0094] First, the first feeding port of the first feeding mechanism c4 and the second feeding port of the second feeding mechanism c4 (at Figure 4 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;

[0095] Next, the first mold seat slides toward the direction close to the second mold seat ( Figure 4 The blocking member c12 on the first mold base c1 slides against the first material discharge port, and the clamping assembly 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 clamping assembly c32 in the horizontal direction. During this sliding process, the first mold base c1 is in a material blocking state;

[0096] After that, the first pushing mechanism performs an extension movement ( Figure 4 The 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 elastic members, and the first pushing mechanism retracts and resets ( Figure 4 The first mold base c1 slides in the opposite direction and returns to the starting position ( Figure 4 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;

[0097] At the same time or afterwards, the second mold base c2 slides toward the direction close to the first mold base c1 ( Figure 4 The first mold base c2 slides forward in the middle of the mold, 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 clamping component c32 moves downward again under the drive of the first lifting mechanism, so that the screw rod part extends into the inner hole of the copper sheet;

[0098] 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 clamping assembly moves upward so that the 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;

[0099] After that, the electric screwdriver moves upward, and the second pushing mechanism moves outward ( Figure 4 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 into the discharge bin c71. The second assembly falls onto the belt conveyor c72 through the discharge bin c71, and is finally transported to the next station;

[0100] Finally, the second pushing mechanism performs a retraction motion ( Figure 4 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 4 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.

[0101] In the locking device for screws and copper sheets of this embodiment, during the entire locking process, the feeding process of the screws and the copper sheets is realized by the first feeding mechanism c4 and the second feeding mechanism c4, without the need for manual feeding, ensuring that the screws and the copper sheets are placed in place in the first placement cavity c115 and the second placement cavity c22 respectively; and when transferring the screws to the copper sheets, the first pushing mechanism is used to complete it, and under the lifting and lowering movement of the clamping assembly, it is ensured that the screw rod 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 discharge bin c71, and finally transports it to the next process via a belt conveyor, so that the locking device has high working efficiency and a high yield rate after the screws and the copper sheets are locked.

[0102] As a first alternative implementation of the above embodiment, the first lifting mechanism and the second lifting mechanism can be independently provided without sharing a guide rail.

[0103] As a variation, when the two chucks of the clamping assembly adopt other structures to achieve automatic movement away from each other, for example, by separately setting up a cylinder and driving the two chucks to move away from each other through the telescopic movement of the cylinder, there is no need to insert the screw locking component into the clearance channel. The screw locking component and the clamping assembly can be set completely independently, and there is no need to set a clearance channel on the clamping assembly.

[0104] 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-mentioned first pushing mechanism. The transfer mechanism can use a 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 chucks of the clamping assembly can be extended into the first placement cavity to clamp the workpiece, and there is no need to set the first pushing mechanism.

[0105] As a further variation, the horizontal or vertical positions of the first mold base and the second mold base are not limited, and they can also be set on the base without sliding; or, the first mold base and the second mold base are not set, and the first placement cavity and the second placement cavity are directly set on the base frame, and the positions of the two placement cavities on the base frame are fixed. As long as the transfer mechanism can move back and forth between the first placement cavity and the second placement cavity, and perform telescopic movement along the notch of the second placement cavity, the workpiece in the first placement cavity can be transferred to the second placement cavity, and through the telescopic movement, the screw part of the screw is installed in the inner hole of the sheet. For example, the transfer mechanism includes a robotic arm, and a robotic hand fixed on the robotic arm.

[0106] As a variation, the first placement cavity may only have a top notch, without the above-mentioned first and second openings. The feeding mechanism directly transports screws and copper sheets from the top notch to the first and second placement cavities, respectively. For example, the feeding mechanism is provided with a separate moving mechanism. After the workpiece is loaded, the moving mechanism drives the feeding mechanism to move away, avoiding the top notch, so as to facilitate the transfer or subsequent locking of the workpiece. Or, for example, the 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 against the above-mentioned abutment position.

[0107] 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 invention.
