Description

Technical Field

[0001] The present invention relates to the technical field of assembly equipment, and in particular to an automatic assembly line for intelligent terminal modules. Background Art

[0002] An intelligent terminal module refers to a terminal device module that integrates certain intelligent functions and processing capabilities. It usually includes components such as a microprocessor, memory, sensor, communication module, etc., and can realize functions such as data acquisition, processing and transmission. Among them, a multi-channel intelligent lighting module refers to an intelligent control device that can simultaneously control multiple lighting circuits or devices. This module usually includes multiple independent output channels, each of which can control the switch, brightness, color and other parameters of a lamp or lighting circuit. Users can use a single multi-channel intelligent lighting module to achieve lighting control of different areas or scenes, thereby improving the intelligence of the lighting system.

[0003] like Fig.11 As shown in the figure, it is a schematic diagram of the splitting of a four-way intelligent lighting module. Fig.11 When the smart lighting module shown is assembled, it is necessary to manually combine the contact piece 64 and the locking piece 63 and then connect them with the fastening screw 65 to make the above two parts a terminal crimping structure, and then insert the above structure as a whole into the installation groove 67, wherein the contact piece has two sides of a wide portion 643 and a narrow portion 641, and the narrow portion 641 is longer than the wide portion 643. The above process will cause the wide portion 643 to be sent into the installation groove 67, and the bayonet 643 on the narrow portion 641 will be engaged with the spring card 66. After completing the assembly of the above terminal crimping structures, the back cover 62 is covered to complete the overall assembly, wherein the back cover 62 has a corresponding card slot, and after the back cover 62 is covered, the spring card 66 will be inserted into the card slot, and the card slot will press the narrow portion 641 to complete the assembly. After the assembly is completed, the fastening screw 65 can be rotated through the through hole 68 on the shell 61 with a screwdriver to achieve the adjustment of the contact piece 64 and the locking piece 63.

[0004] In the process of assembling the crimping structure and the shell, manual operation is adopted for assembly. However, there are some problems with manual operation. First, the operation requires connecting multiple contacts with the locking members respectively and inserting them into the corresponding installation slots in sequence. There are many operation processes. Manual operation requires a lot of manpower input and has low work efficiency. It is difficult to meet the needs of large-scale production, resulting in high production costs. Secondly, manual operation is easily affected by human factors, such as operating errors, increased fatigue, etc., which cause quality fluctuations and instability in the production process. When assembling with automated equipment, since the above-mentioned assembly parts are mostly special-shaped structures, and the assembly process requires the assembly of a small structure (terminal crimping structure) and the assembly of this structure with the shell, the main problem of assembly during the batch feeding process is how to place different special-shaped parts (locking member 63 and contact 64) in a posture that is convenient for assembly. Otherwise, when using the chuck to pick up the material, not only can the clamping not be completed stably, but also the assembly cannot be performed directly after clamping. It is necessary to use a complex system to adjust the direction of the parts, which is difficult to operate and not conducive to practical application. Summary of the invention

[0005] The object of the present invention is to provide an automatic assembly line for intelligent terminal modules to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] An automatic assembly line for intelligent terminal modules comprises: a main body, wherein a controller is arranged inside the main body; a material controlling three-axis component, wherein the material controlling three-axis component is fixedly mounted on the top of the main body, and a chuck for clamping a shell is installed at a movable end of the material controlling three-axis component; a material picking three-axis component, wherein the material picking three-axis component is fixedly mounted on the top of the main body, and a chuck for clamping a contact piece is installed at a movable end of the material picking three-axis component; a picking component, wherein the picking component is arranged on the top of the main body, and the picking component is used to remove the contact piece whose placement posture is not convenient for assembly; a sorting component, wherein the sorting component is arranged on the top of the main body, and the sorting component is used to convey a locking piece whose posture is convenient for assembly; and a connecting component, wherein the connecting component is used to connect the placed locking piece and the contact piece into a whole by means of a fastening screw, and then assemble the connected whole with the shell.

[0008] By adopting the above technical scheme, by setting up picking components and sorting components, it is possible to screen out postures that are convenient for assembly during the transportation of contacts and locking parts, and then conveniently use the set connecting components to combine the above two components, and can rely on the above connecting action to complete the assembly of the combined components and the shell, while the above picking and sorting processes can perform assembly operations at the same time, the assembly actions are continuous, and the waiting time between each action is short, thereby greatly improving the efficiency of assembly.

[0009] A further improvement of the technical solution of the present invention is that the picking component includes a first vibration plate fixedly connected to the top of the main body, and the output port of the first vibration plate is fixedly connected to two material guide rods, and the two material guide rods are provided with an extension portion extending to the opposite side at one end away from the first vibration plate, and the two material guide rods are fixedly connected at one end close to the extension portion, a notch portion is provided at the central position of one of the material guide rods, and a guide portion is provided at one end of the material guide rod located at the notch portion.

[0010] By adopting the above technical scheme, during the vibration of the first vibration disk, the contact piece will be transported to the discharge port and fall between the two guide rods. The contact piece is arranged in an η shape, wherein one side is arranged with a shorter wide part and a longer narrow part, wherein the narrow part has a bayonet, and a screw hole is provided on the wide part; the contact piece has a variety of postures when it falls on the two guide rods, and the contact pieces with different postures move to the extension part through the two guide rods, and the contact pieces with postures that are not convenient for direct assembly will fall downwards and be removed, thereby obtaining contact pieces with postures that are convenient for assembly.

[0011] A further improvement of the technical solution of the present invention is that: the sorting component includes a second vibration plate fixedly connected to the top of the main body, the output port of the second vibration plate is fixedly connected to a screening tube, the end face shape inside the screening tube is adapted to the shape of one of the views of the block parts, and a screening trough is provided at the bottom of the screening tube for the block parts that are in a dropped-out posture for easy assembly; a straight vibration feeder is fixedly connected to the top of the main body, and an assembly table is also fixedly connected to the top of the main body, and a feeding rail is fixedly connected to the top of the assembly table, a transfer port is provided on one side of the feeding rail, and both ends of the straight vibration feeder are respectively communicated with the transfer port and the screening tube; a side give way groove is provided in a partial area on the inner side of the feeding rail, and a bottom give way groove communicated with the feeding rail is provided on the top of the assembly table.

[0012] By adopting the above technical solution, the cross-section of one end of the locking piece is a rectangular structure and has the smallest area relative to other surfaces. During the conveying process of the locking piece, the locking piece can only pass through when this surface is along the axial direction of the screen pipe. Therefore, in this way, the locking piece that can pass through the screen pipe is limited to move along a certain conveying direction, thereby realizing the adjustment of the posture of the locking piece entering the discharge port of the second vibration plate.

[0013] A further improvement of the technical solution of the present invention is that: the connecting component includes an electric telescopic rod 1, the piston rod of the electric telescopic rod 1 extends to the interior of the feeding rail and is fixedly connected to a push block, and the push block is slidably connected to both sides of the inner wall of the feeding rail; both sides of the assembly table are fixedly connected to mounting frames, a flip plate is provided on the side close to the mounting frame, an electric telescopic rod 2 is fixedly installed on one side of the flip plate, the piston rod of the electric telescopic rod 2 extends to the other side of the flip plate and is fixedly connected to a force block, a rotating seat is rotatably connected between the two sides of the flip plate, the two end surfaces of the rotating seat are provided with through spline grooves, and a spline shaft is slidably connected between the inner walls of the spline groove, one end of the spline shaft is fixedly connected to the force block, and the end of the spline shaft away from the force block is fixedly connected to a screwdriver bit, and the screwdriver bit has an adsorption structure.

[0014] By adopting the above technical solution, when the electric telescopic rod 2 and the screwdriver bit are in a horizontal state, the electric telescopic rod 2 is controlled to be retracted, so that the force block drives the spline shaft to move, and the screwdriver bit drives the fastening screw to move toward the feeding rail, and extends into the installation groove through the through hole until it contacts the screw hole on the contact piece, and then the screwdriver bit is driven to rotate by the tightening motor to tighten the fastening screw between the contact piece and the locking piece to connect the two together.

[0015] A further improvement of the technical solution of the present invention is that the connecting component also includes a flipping motor, which is fixedly connected to one side of one of the mounting frames, and the output end of the flipping motor extends to the other side of the mounting frame and is fixedly connected to the rotating shaft of the flip plate; a tightening motor is fixedly installed on one side of the flip plate, and the output end of the tightening motor extends to the other side of the flip plate and is connected to the rotating seat through mutually meshing gears; a screw feeder is fixedly installed on the top of the main body.

[0016] By adopting the above technical scheme, the flip motor is controlled to drive the flip plate to flip so that the screwdriver bit is directly below the flip plate. At this time, the electric telescopic rod 2 is controlled to be retracted, thereby pushing the force block to move and driving the spline shaft to move, so that the screwdriver bit moves downward. At the same time, the tightening motor is controlled to work so that the rotating seat rotates slowly, and the spline groove cooperates with the spline shaft to make the screwdriver bit rotate slowly. A screw feeder is provided under the screwdriver bit to provide a fastening screw with the screw head facing upward. When the cross head on the screwdriver bit fits with the cross slot on the fastening screw, the suction nozzle can adsorb the fastening screw through external negative pressure to realize screw material removal.

[0017] A further improvement of the technical solution of the present invention is that a limiting plate used in conjunction with the mounting frame and the flip plate is fixedly connected, and the limiting plate is used to limit the flipping angle range of the flipping plate to 90°.

[0018] By adopting the above technical solution, the flipping angle of the flip plate is limited by the limit plate, so that the screwdriver bit can be in a vertical state when the above-mentioned fastening screw is taking material; and when the fastening screw is tightened, the screwdriver bit can be in a horizontal state to avoid slipping or unstable adsorption.

[0019] A further improvement of the technical solution of the present invention is that: one side of the screening tube is fixedly connected to a support frame, one side of the support frame is fixedly connected to an electric telescopic rod three, the output end of the electric telescopic rod three extends to the interior of the support frame and is fixedly connected to an L-shaped plate, a through groove is provided at the bottom of the screening tube, a support plate is rotatably connected between the inner walls of the through groove, and one side of the L-shaped plate is in contact with the support plate; one side of the inner wall of the screening tube is provided with a positioning groove, an optical sensor is fixedly installed inside the positioning groove, the optical sensor and the electric telescopic rod three are both electrically connected to the controller, and one corner on the inner side of the L-shaped plate is set as a rounded corner.

[0020] By adopting the above technical solution, an optical sensor is set up. When the locking piece passes through the optical sensor, the signal of the locking piece facing backward will be irradiated on the inner side of the locking piece through the screw hole, and then reflected by the optical sensor, indicating that the locking piece is oriented with the screw hole facing backward at this time, so it cannot be used directly for assembly. At this time, the controller controls the electric telescopic rod to contract three times, and then the L-shaped plate is retracted. The bottom of the inner side of the L-shaped plate contacts the bottom of the support plate. The retraction of the L-shaped plate will cause the support plate to lose support and then flip downward, thereby causing the locking piece (not meeting the orientation requirement) that is at the top of the support plate in the screening tube to fall downward into the first material guide frame.

[0021] A further improvement of the technical solution of the present invention is that: a groove is provided on one side of the inner wall of the screening tube, an air bag is fixedly connected to one side of the inner wall of the groove, a piston cylinder is fixedly connected to one side of the support frame, a piston plate is slidably connected between the inner walls of the piston cylinder, the piston cylinder and the air bag are connected by a pipeline, a sliding rod is slidably connected to one side of the support frame, one end of the sliding rod is fixedly connected to a pressure plate, one end of the sliding rod away from the pressure plate extends to the interior of the piston cylinder and is fixedly connected to the piston plate, and a return spring is sleeved on the outer side of the sliding rod.

[0022] By adopting the above technical solution, when a locking piece that does not meet the requirements appears, the subsequent locking piece will continue to be transported during the flipping of the pallet because the first vibrating disk continues to work. If two adjacent locking pieces are too compact, the next locking piece will move to the top of the pallet when the locking piece that does not meet the requirements has not completely fallen out. At this time, it is easy for the locking piece to fall out accidentally, and it is even easy for the locking piece to fall and cause material jamming during the closing process of the pallet. Therefore, by arranging an airbag, during the retraction process of the above-mentioned electric telescopic rod three, the force-bearing block will be pushed to move, and then the piston plate will be pushed to move through the sliding rod, so that the piston cylinder inflates the airbag through the pipeline, so that the airbag expands and squeezes the locking piece in contact with it, thereby preventing the subsequent locking piece from being transported further; and after the electric telescopic rod three is reset, the airbag will retract into the initial groove under the elastic force of the reset spring, so as not to interfere with subsequent transportation.

[0023] A further improvement of the technical solution of the present invention is that a first material guide frame is fixedly connected to the top of the main body and below the screen pipe, and a second material guide frame is fixedly connected to the top of the main body and below the guide rod, and both the first material guide frame and the second material guide frame are inclined.

[0024] By adopting the above technical solution, it is convenient to discharge the locking parts and contact pieces with inconsistent postures from the first material guide rack and the second material guide rack respectively, and to receive them by arranging a collection container outside.

[0025] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0026] 1. The present invention provides an automatic assembly line for intelligent terminal modules. By setting a picking component and a sorting component, it is possible to screen out postures that are convenient for assembly during the conveying process of the contact piece and the locking piece, and then conveniently use the set connecting component to combine the above two components, and can rely on the above connecting action to complete the assembly of the combined components and the shell, and the above picking and sorting processes can perform assembly operations at the same time, the assembly actions are continuous, and the waiting time between each action is short, thereby greatly improving the efficiency of assembly.

[0027] 2. The present invention provides two guide rods to transport the contact pieces and utilizes the shape characteristics of the contact pieces so that when the contact pieces in different postures pass through the two guide rods and move to the extension portion, the contact pieces in postures that are not convenient for direct assembly will fall downward and be removed, thereby obtaining contact pieces in postures that are convenient for assembly, which greatly facilitates subsequent assembly operations.

[0028] 3. The present invention sets a screening tube that matches the size and shape of a side surface with the smallest area of ​​the locking piece. During the process of conveying the locking piece on the second vibration plate, the direction of the locking piece will be adjusted, so that the locking piece will only be conveyed with a smaller surface facing the conveying direction, thereby enabling the locking piece to be quickly arranged in the direction, and the arrangement process is carried out along with the conveying process, thereby not affecting the assembly efficiency.

[0029] 4. The present invention provides a screwdriver bit for the structure to be adsorbed, which can be used to fix the fastening screw between the locking piece and the contact piece, and the action of the screwdriver bit when it is reset can be used to bring the fixed structure into the installation groove, thereby making the assembly process of the contact piece and the locking piece and the assembly process of the above structure and the shell coherent, greatly improving the efficiency of assembly, while reducing unnecessary operations, which is beneficial to practical applications.

[0030] 5. The present invention provides a through groove at the bottom of the screening tube and an openable support plate. For locking parts that are inconvenient to assemble, the signal of the optical sensor will be irradiated to the inner side of the locking parts through the screw holes, and then the optical sensor will sense the signal after reflection, that is, the controller controls the electric telescopic rod to contract three times, and then the L-shaped plate is retracted, and the bottom of the inner side of the L-shaped plate contacts the bottom of the support plate. The retraction of the L-shaped plate will cause the support plate to lose support and then flip downward, so that the locking parts that are on the top of the support plate in the screening tube will fall downward, so as to screen out the locking parts that are inconvenient to install.

Since the shapes of the discharge port and the screen tube 52 (the two have the same shape and size) match, and match the left and right side surfaces of the locking piece 63 in the above-mentioned posture; the locking piece 63 is a structure similar to a rectangular parallelepiped as a whole, and its cross-section in the left and right directions is a rectangular structure and has the smallest area relative to other surfaces. During the conveying process of the locking piece 63, it can only pass through when this surface is along the axial direction of the screen tube 52. Therefore, in this way, it is limited that the locking piece 63 that can pass through the screen tube 52 will only move along the conveying direction with the left and right sides, thereby realizing the arrangement of the posture of the locking piece 63 entering the discharge port of the second vibration plate 51.

[0060] like Figure 7 , Figure 8 and Fig. 9 As shown, preferably, the connecting component includes an electric telescopic rod 71, the piston rod of which extends to the interior of the feed rail 56 and is fixedly connected to a push block 72, and the push block 72 is slidably connected to both sides of the inner wall of the feed rail 56; both sides of the assembly table 55 are fixedly connected to mounting frames 73, and a flip plate 75 is provided on the side close to the mounting frame 73, and an electric telescopic rod 2 76 is fixedly installed on one side of the flip plate 75, and the piston rod of the electric telescopic rod 2 76 extends to the other side of the flip plate 75 and is fixedly connected to a force block 77, and a rotating seat 78 is rotatably connected between the two sides of the flip plate 75, and a through spline groove is provided on the two end surfaces of the rotating seat 78, and a spline shaft 79 is slidably connected between the inner walls of the spline groove, one end of the spline shaft 79 is fixedly connected to the force block 77, and the end of the spline shaft 79 away from the force block 77 is fixedly connected to a screwdriver 710, and the screwdriver 710 has an adsorption structure.

[0061] In this embodiment, when the electric telescopic rod 2 76 and the screwdriver bit 710 are in a horizontal state, the electric telescopic rod 2 76 is controlled to be retracted, so that the force block 77 drives the spline shaft 79 to move, so that the screwdriver bit 710 drives the fastening screw 65 to move toward the feeding rail 56, and extends into the mounting groove 67 through the through hole 68 until it contacts the screw hole on the contact piece 64, and then the screwdriver bit 710 is driven to rotate by the tightening motor 711 to tighten the fastening screw 65 between the contact piece 64 and the locking piece 63 to connect the two together.

[0066] In this embodiment, the flipping angle of the flip plate 75 is limited by a limiting plate so that the bit 710 can be in a vertical state when the fastening screw 65 takes the material; and when the fastening screw 65 is tightened, the bit 710 can be in a horizontal state to avoid slipping or unstable adsorption.

[0067] Example 2

[0068] like Figure 6 and Fig.13 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, one side of the screening tube 52 is fixedly connected to a support frame 81, one side of the support frame 81 is fixedly connected to an electric telescopic rod three 83, the output end of the electric telescopic rod three 83 extends to the inside of the support frame 81 and is fixedly connected to an L-shaped plate 85, a through groove 82 is provided at the bottom of the screening tube 52, a support plate 84 is rotatably connected between the inner walls of the through groove 82, and one side of the L-shaped plate 85 is in contact with the support plate 84; a positioning groove 86 is provided on one side of the inner wall of the screening tube 52, an optical sensor 87 is fixedly installed inside the positioning groove 86, the optical sensor 87 and the electric telescopic rod three 83 are both electrically connected to the controller, and one corner of the inner side of the L-shaped plate 85 is set as a rounded corner.

[0069] In this embodiment, the locking member 63 can only be transported with the hollow portion facing up and down due to the limitation of the screening tube 52. However, in this posture, the direction (front or back) of the screw hole on the locking member 63 cannot be adjusted, and only the screw hole facing forward can be directly assembled.

[0070] Therefore, in this embodiment, an optical sensor 87 is also provided. When the locking member 63 passes through the optical sensor 87, the signal of the locking member 63 facing backward will be irradiated on the inner side of the locking member 63 through the screw hole, and then reflected by the optical sensor 87, indicating that the locking member 63 is oriented in the direction of the screw hole toward the rear, so it cannot be directly used for assembly. At this time, the controller controls the electric telescopic rod 3 83 to contract, and then the L-shaped plate 85 is retracted, and the bottom of the inner side of the L-shaped plate 85 contacts the bottom of the support plate 84. The retraction of the L-shaped plate 85 will cause the support plate 84 to lose support and then flip downward, so that the locking member 63 (not meeting the orientation requirement) at the top of the support plate 84 in the screening tube 52 falls downward into the first material guide frame 11, and slides downward along the first material guide frame 11 to the external container. After a short delay, the electric telescopic rod 3 83 is controlled to extend again to push the L-shaped plate 85 to move, so that the support plate 84 is closed, and the feeding can continue.

[0071] Example 3

[0072] like Figure 6 and Fig.13As shown, on the basis of Example 2, the present invention provides a technical solution: preferably, a groove 93 is opened on one side of the inner wall of the screen tube 52, an air bag 94 is fixedly connected to one side of the inner wall of the groove 93, a piston cylinder 91 is fixedly connected to one side of the support frame 81, a piston plate 92 is slidably connected between the inner walls of the piston cylinder 91, the piston cylinder 91 and the air bag 94 are connected by a pipeline, a slide rod 95 is slidably connected to one side of the support frame 81, one end of the slide rod 95 is fixedly connected to a pressure plate 96, one end of the slide rod 95 extends to the interior of the piston cylinder 91 away from the pressure plate 96 and is fixedly connected to the piston plate 92, and a return spring 97 is sleeved on the outer side of the slide rod 95.

[0073] In this embodiment, when a locking piece 63 that does not meet the requirements appears, during the flipping process of the support plate 84, since the first vibrating plate 41 continues to work, the subsequent locking piece 63 will continue to be transported. If two adjacent locking pieces 63 are too close together, the next locking piece 63 will move to the top of the support plate 84 before the locking piece 63 that does not meet the requirements has completely fallen out. At this time, it is easy to cause the locking piece 63 to fall out accidentally, and it is even easy to cause the locking piece 63 to fall off during the closing process of the support plate 84, resulting in a jam. By providing the airbag 94, during the retraction process of the above-mentioned electric telescopic rod three 83, the force block 77 will be pushed to move, and then the piston plate 92 will be pushed to move through the sliding rod 95, so that the piston cylinder 91 inflates the airbag 94 through the pipeline, so that the airbag 94 expands and squeezes the locking piece 63 in contact with it, thereby making it impossible for the subsequent locking piece 63 to continue to be transported; and after the electric telescopic rod three 83 is reset, the airbag 94 will be retracted into the initial groove 93 under the elastic force of the reset spring 97, so as not to interfere with subsequent transportation.

[0074] like Figure 2 and Figure 3 As shown, preferably, a first material guide rack 11 is fixedly connected to the top of the main body 1 and below the screen tube 52, and a second material guide rack 12 is fixedly connected to the top of the main body 1 and below the guide rod 42, and both the first material guide rack 11 and the second material guide rack 12 are inclined.

[0075] In this embodiment, the locking member 63 and the contact piece 64 with inconsistent postures can be respectively discharged outward from the first material guide rack 11 and the second material guide rack 12 by arranging a collection container outside to receive them.

[0076] The following is a detailed description of the working principle of the intelligent terminal module automatic assembly line.

[0077] like Figure 1-Figure 13As shown, the touch 64 is poured into the first vibration plate 41, and the locking piece 63 is poured into the second vibration plate 51, and the intelligent module shell 61 is conveyed to the main body 1 by an external conveyor line, and the three-axis material-picking component 3 is controlled to work to the end of the conveyor line and the intelligent module shell 61 is clamped by a chuck, and then the three-axis material-picking component 3 is controlled to work to send the shell 61 (the side connected to the back cover 62) to contact the side of the assembly table 55 with the side give way groove 58.

[0078] During the above process, the second vibration plate 51 and the first vibration plate 41 are controlled to work to feed the parts:

[0079] The second vibration plate 51 works to move the locking member 63 upward to the position of the discharge port, wherein, Fig.11 In the orientation shown, the locking member 63 is conveyed from right to left during the conveying process, and the screw hole on the locking member 63 is facing forward, because the shapes of the discharge port and the inner part of the sieve tube 52 (both of the same shape and size) match, and match the left and right sides of the locking member 63 in the above-mentioned posture;

[0080] The locking piece 63 is a rectangular parallelepiped structure as a whole, and its cross section in the left-right direction is a rectangular structure and has the smallest area relative to other surfaces. During the conveying process of the locking piece 63, it can only pass through when this surface is along the axial direction of the sieve tube 52. Therefore, in this way, the locking piece 63 that can pass through the sieve tube 52 is limited to move along the conveying direction with the left and right surfaces; and due to the limitation of the sieve tube 52, the locking piece 63 can only be conveyed with the hollow part facing up and down, but in this posture, the direction (front and back) of the screw hole on the locking piece 63 cannot be adjusted. Only the screw hole position facing forward can be directly assembled, and when the locking piece 63 facing backward passes through the optical sensor 87, the signal will be irradiated on the locking piece 63 through the screw hole. The inner side of the optical sensor 87 is then reflected so that the optical sensor 87 senses a signal, which means that the locking member 63 is oriented such that the screw hole is facing backwards, so it cannot be directly used for assembly. At this time, the controller controls the electric telescopic rod 3 83 to retract, thereby retracting the L-shaped plate 85, and the bottom of the inner side of the L-shaped plate 85 contacts the bottom of the support plate 84. The retraction of the L-shaped plate 85 will cause the support plate 84 to lose support and then flip downward, thereby causing the locking member 63 (not meeting the orientation requirement) at the top of the support plate 84 in the screening tube 52 to fall downward into the first guide frame 11, and slide downward along the first guide frame 11 to the external container. After a short delay, the electric telescopic rod 3 83 is controlled to extend again to push the L-shaped plate 85 to move, so that the support plate 84 is closed.

[0081] During the flipping process of the above-mentioned support plate 84, since the first vibrating disk 41 continues to work, the subsequent locking piece 63 will continue to be transported. If two adjacent locking pieces 63 are too compact, the next locking piece 63 will move to the top of the support plate 84 when the locking piece 63 that does not meet the requirements has not completely fallen out. At this time, it is easy to cause the locking piece 63 to fall out accidentally, and it is even easy to cause the locking piece 63 to fall off and cause the material to get stuck during the closing process of the support plate 84. Therefore, by providing an air bag 94, during the retraction process of the above-mentioned electric telescopic rod three 83, the force block 77 will be pushed to move, and then the piston plate 92 will be pushed to move through the sliding rod 95, so that the piston cylinder 91 inflates the air bag 94 through the pipeline, so that the air bag 94 expands and squeezes the locking piece 63 in contact with it, thereby making it impossible for the subsequent locking piece 63 to continue to be transported; and after the electric telescopic rod three 83 is reset, the air bag 94 will be retracted into the initial groove 93 under the elastic force of the reset spring 97, so as not to interfere with subsequent transportation.

[0082] The above process will make the locking piece 63 only keep the state with the screw hole facing forward. The locking piece 63 in this posture is sent to the feeding rail 56 through the direct vibration feeder 54, and the electric telescopic rod 71 is controlled to extend, so that the push block 72 pushes the locking piece 63 to move to the top of the bottom clearance groove 59 (set to a fixed position) and wait for assembly.

[0083] During the vibration of the first vibration plate 41, the contact piece 64 is transported to the discharge port and falls between the two guide rods 42. The contact piece 64 is arranged in an η shape, wherein one side is arranged in a shorter wide portion 643 and a longer narrow portion 641, wherein the narrow portion 641 has a bayonet 642, and a screw hole is provided on the wide portion 643; the contact piece 64 falls on the two guide rods 42 in various postures, such as Figure 4As shown in the figure, referring to the figure, the one on the guide rod 42 that is farthest from the first vibration plate 41 is defined as the first one, and the numbers are increased in sequence as it gradually approaches the first vibration plate 41; for the first one, it can move along the guide rod 42 until it reaches the extension part 43. Since the spacing of the extension part 43 gradually increases, the contact piece will stop at the extension part 43 after arriving; for the second one, when it reaches the extension part 43, it will fall to one side; for the third and fourth ones, when they reach the extension part 43, they will fall directly from the middle position of the extension part 43, among which the third one usually cannot pass through the notch part 45, and when it reaches the notch part 45 at the narrow part 641, its narrow part 641 is narrower than the notch part 45. , so it will directly flip over and then fall directly downward in the notch portion 45; the sixth one cannot be directly clamped for assembly because its placement direction is opposite to that of the first one, and its screw hole direction is also opposite to that of the first one. When the narrow portion 641 passes through the notch portion 45, it will directly flip over to the state of the seventh one; when the seventh one is sent to the extension portion 43, it is the same as the second situation. When it reaches the extension portion 43, it will fall to the other side. For those that can pass through, that is, the same posture as the first one, there is a slight skew when passing through the notch portion 45, but the degree of skewness is not too large. The skewed part continues to be transported along the guide portion 46 until it is straightened to avoid the skewed part from colliding with the end of the notch portion 45 and causing material jamming.

[0084] After the above operations, the contact piece 64 that meets the assembly posture stays in a fixed position, and the three-axis material picking component 3 is controlled to work above the contact piece 64, and the contact piece 64 is clamped by the chuck, and the contact piece 64 is placed on the locking piece 63 through the three-axis material picking component 3. The placement state is that the narrow part 641 passes through the locking piece 63 and extends into the bottom clearance groove 59. After placement, the chuck no longer clamps the contact piece 64, but moves the chuck to a closer distance, and then the chuck is used to press the structure downward from the top of the above-mentioned combined structure to keep the structure fixed.

[0085] After placement, the flip motor 74 is controlled to work, driving the flip plate 75 to flip so that the screwdriver bit 710 is directly below the flip plate 75. At this time, the electric telescopic rod is controlled to be retracted, thereby pushing the force block 77 to move, and driving the spline shaft 79 to move, so that the screwdriver bit 710 moves downward, and at the same time, the tightening motor 711 is controlled to work, so that the rotating seat 78 rotates slowly, and cooperates with the spline shaft 79 through the spline groove to make the screwdriver bit 710 rotate slowly. A screw feeder 13 is provided below the screwdriver bit 710 to provide a fastening screw 65 with the screw head facing upward. When the cross head on the screwdriver bit 710 fits with the cross groove on the fastening screw 65, it reaches a position where the material can be taken. At this time, the tightening motor 711 is controlled to stop working, and the external device is controlled to draw negative pressure to the screwdriver bit 710 (the screwdriver bit 710 is set with a suction nozzle at the center of the cross head, And an air suction pipe is provided inside, and negative pressure can be generated in the air suction pipe by external negative pressure extraction, so that the suction nozzle can tightly adsorb the fastening screw 65), and then the fastening screw 65 is sucked up; after taking the fastening screw 65, the electric telescopic rod 76 is controlled to extend, so that the screwdriver bit 710 and the fastening screw 65 move upward; then the flip motor 74 is controlled to work, so that the electric telescopic rod is flipped to a horizontal state, and the screwdriver bit 710 and the fastening screw 65 are also in a state parallel to the ground, and the electric telescopic rod is controlled to be retracted, so that the screwdriver bit 710 drives the screw to move toward the feeding rail 56, and extends into the installation groove 67 through the through hole 68 until it contacts the screw hole on the contact piece 64, and then the screwdriver bit 710 is driven to rotate by the tightening motor 711 to tighten the fastening screw 65 to between the contact piece 64 and the locking piece 63, so as to connect the two together;

[0086] Control the material picking triaxial component 3 to move the chuck away (to pick up materials for the next assembly cycle), then control the batch head 710 to retract, and then pull the above-mentioned assembly (locking piece 63, contact piece 64 and fastening screw 65) into the mounting hole. The above process can be assisted by controlling the electric telescopic rod 71 to extend to push in, so that the bayonet 642 is stuck in the spring card 66, thereby completing the assembly; after the assembly is completed, the electric telescopic rod 71 can be controlled to retract to pick up the next locking piece 63, and at the same time control the material control triaxial component 2 to work, so that the next mounting groove 67 on the shell 61 is opposite to the side give way groove 58. In this process, the activity of the material control triaxial component 2 is the distance between two mounting grooves 67 on a certain axis. Repeat the operation until the assembly of the internal structures of all mounting grooves 67 is completed, and the shell 61 is sent out after the installation is assembled using the material control triaxial component 2.

[0087] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
