[0042] Furthermore, in step S8, when the resistance value of the insertion test is unqualified, all subsequent processes of the multi-way socket run in an idle stroke.

[0043] Furthermore, step S2 includes the following steps: S21. The switch at the output end of the discharging mechanism I 101 enters the jaws of the clamping cylinder 1034 located at the first position. S22. The color of the switch is detected by the detection sensor I 108, and when the color is unqualified, the switch is transferred to the discharge port 109 by the transfer manipulator I 102. S23. The driving device I drives the clamping cylinder 1034 to rotate 180 degrees and flip it from the first position to the second position, placing the switch upside down in the material waiting groove 106. S24. The transfer manipulator I 102 transfers the switch in the material waiting groove 106 to the switch placement groove of the ejecting mechanism 107 located directly below the conveying device. S25. When the upper cover moves to directly above the ejector mechanism 107, the ejector mechanism 107 jacks up the switch in the switch feeding slot and presses it into the switch hole of the upper cover.

[0044] Further, in step S23, the tipping cylinder 1031 of the driving device I pushes the rack I 1032 to move, drives the gear I 1033 to rotate, and further drives the clamping cylinder 1034 to rotate until it contacts the limit block at the second position and reaches the second position. The jaws of the clamping cylinder 1034 loosen and invert the switch into the material waiting slot 106; then the tipping cylinder 1031 drives the gear I 1033 to rotate in the reverse direction, and further drives the clamping cylinder 1034 to rotate in the reverse direction until it contacts the limit block at the first position and reaches the first position.

[0045] Further, step S3 includes the following steps: S31. The protection door at the output end of the discharging mechanism II 201 enters the material transfer slot 20351 of the turntable located at the third position. S32. The driving device II drives the turntable 2035 to rotate to the fourth position and makes the protection door in the material transfer slot 20351 parallel to the installation angle of the protection door on the multi-position socket. S33. The material transfer manipulator II 202 clamps the protection door in the material transfer slot 20351 at the fourth position and assembles it to the protection door installation position of the multi-position socket.

[0046] Further, in step S32, the tipping cylinder 2031 of the driving device II pushes the rack II 2032 to rotate, drives the gear II 2033 and the turntable 2035 to rotate until the limit protrusion 20352 on the side wall of the turntable 2035 contacts one end of the limit groove 20342 on the side wall of the installation groove 20340 and reaches the fourth position; after the material transfer manipulator II 202 grabs the protection door at the fourth position, the tipping cylinder 2031 pushes the rack II 2032 to rotate in the reverse direction, and further drives the gear II 2033 and the turntable 2035 to rotate in the reverse direction until the limit protrusion 20352 on the side wall of the turntable 2035 contacts the other end of the limit groove 20342 on the side wall of the installation groove 20340 and reaches the third position.

[0047] Further, step S9 includes the following steps: S91. The small panel at the discharging end of the discharging mechanism III 61 enters the material placement plane 645a of the flipping platform 645 located at the fifth position, and the suction holes I 6450 on the material placement plane 645a generate negative pressure and suck the small panel. S92. The misfeeding cylinder 641 of the misfeeding mechanism 64 pushes the mounting seat 642 to move towards the sixth position. During the movement of the mounting seat 642, the slewing cylinder 644 rotates and flips the small panel 180 degrees. After the mounting base 642 reaches the sixth position, the negative pressure in the adsorption hole I 6450 is eliminated or positive pressure is generated, causing the small panel to fall onto the placement surface of the material waiting base 63. The first positioning protrusion 631 on the placement surface inserts into the mounting hole on the small panel to position the small panel. S94. The adsorption surface 621a of the material transfer manipulator III 62 adheres to the small panel. The adsorption hole II 6212 generates negative pressure to suck the small panel and assemble it to the panel mounting position of the rear cover.

[0048] Furthermore, the comprehensive test in step S10 includes switch test, high-voltage test, polarity test, and resistance test.

Specifically, there are two parallel conveyor belts with a gap between them, forming a working space for assembling a switch 14' and providing space for supporting the multi - socket from below during the assembly operation. During conveying, the length direction of the multi - socket 1' is parallel to the conveying direction of the conveying device.

[0053] There are multiple workstations arranged on the conveying path of the conveying device. In this application, they sequentially include a general loading station op10, a switch assembly station op20, a protection door assembly station op30, a manual assembly station op40, a latching and unloading station op50, a manual wire threading station op60, a soldering station op70a, a plug - in test station op70b, a small panel assembly station op80, a comprehensive test station op90a, a marking station op90b, and a finished product unloading station op100.

[0054] The general loading station op10 is used for loading the upper cover 11' of the multi - socket. When loading, the upper cover 11' is equipped with a grounding terminal. The general loading station op10 is the exposed end at the head of the conveying device.

[0055] A roller conveyor line is provided at one end of the general loading station op10 for conveying the material box containing the upper cover 11' and returning the empty material box. For the convenience of operation and to avoid misoperation, the roller conveyor line includes an inlet roller conveyor line and an outlet roller conveyor line. Among them, the inlet roller conveyor line is used for conveying the full material box containing the upper cover 11'. Workers at the general loading station op10 can place this full material box at a position convenient for loading or directly pick up materials at the end of the inlet roller conveyor line, that is, without manual handling. When all the upper covers 11' in the material box are loaded, it becomes an empty material box. Place this empty material box on the outlet roller conveyor line for material box return, and then operate on the full material box on the inlet roller conveyor line, and so on in sequence.

[0056] A switch assembly device 1 is provided at the switch assembly station op20. The switch assembly device 1 is used for assembling the switch 14' into the switch hole of the upper cover 11'.

[0057] A protection door assembly device 2 is provided at the protection door assembly station op30. The protection door assembly device 2 is used for assembling the protection door 15' onto the protection door installation position of the upper cover 11'.

[0058] The manual assembly station op40 is an exposed section of the conveying device where manual operations can be carried out. Specifically, it is used for manually assembling the conductive sheet and the rear cover 12' onto the upper cover 11'.

[0059] At the binding and blanking station op50, there is a first screw locking device 31 and a semi-finished product blanking device 32. Among them, the first screw locking device 31 is used to bind (fix) the rear cover 12' to the upper cover 11' through screws; the semi-finished product blanking device 32 is used to automatically move the multi-position socket to the jig 2' for the next stage of assembly.

[0060] The manual wire threading station op60 is also an exposed conveying device that can perform manual operations. Specifically, it is used for manually threading the wire into the multi-position socket and inserting the plug into the socket of the jig 2', so that the wiring end of the wire is connected to the wiring end of the switch and the grounding end wiring end in the multi-position socket.

[0061] In order to improve work efficiency and reduce the labor intensity of workers, there is a shelf and a loading robot for automatically loading and unloading the shelf at the manual wire threading station op60. Among them, the shelf is located directly in front of the conveying device, that is, directly in front of this manual wire threading station op60. There are two pallets on the shelf that can be lifted and lowered synchronously. The position directly in front of the worker and convenient for taking materials is defined as the material taking position. The upper end or lower end of the material taking position is the waiting material position. When one pallet is located at the material taking position, the other pallet is located at the waiting material position; during operation, the worker takes out the materials (wires) in the material box at the material taking position and performs manual wire threading operations. When all the materials at the material taking position are taken out and it becomes an empty material box, at this time, the two pallets are lifted or lowered synchronously, so that the original pallet (empty material box) located at the material taking position is moved to the waiting material position. Correspondingly, the original pallet (full material box) located at the waiting material position is moved to the material taking position. At this time, the full material box located at the material taking position can continue to be taken for materials; at the same time, the loading robot can take out the empty material box located at the waiting material position and place the full material box filled with materials on the waiting material position to achieve automatic replenishment of materials, and so on in turn; it greatly improves work efficiency and avoids the phenomenon of empty travel and missed assembly caused by material vacancies.

[0072] Refer to Figures 6 - 7 , the positioning and supporting mechanism includes a bracket base 1052. The bracket base 1052 can move horizontally along the conveying direction of the multi-position socket. A conveying channel is provided on the bracket base 1052, and the conveying channel can accommodate the conveying device to pass through. Clamping plates 1053 are provided on both sides of the upper end of the bracket base 1052, which are driven by a clamping cylinder 1054.

The turning mechanism 103 is used to vertically turn the switch 14' at the discharging end of the discharging mechanism I 101 by 180 degrees and place it in the material waiting groove 106. The vertical turning is used to turn the switch board with the wiring end facing down output by the discharging mechanism I 101 to the wiring end facing up and place it in the material waiting groove 106 for easy assembly of the switch; the material transferring manipulator I 102 is used to transfer the switch 14' on the material waiting groove 106 to the switch placement groove of the material ejecting mechanism 107 directly below the conveying device at this station. A material ejecting cylinder 1071 is provided directly below the switch placement groove. The material ejecting cylinder 1071 is used to jack up the switch in the switch placement groove and press the switch into the switch hole of the multi-position socket from bottom to top, thereby realizing the assembly of the switch.

[0074] In order to improve the assembly efficiency, in this application, the discharging end of the discharging mechanism I 101, the turning mechanism 103, the material waiting groove 106, and the material ejecting mechanism 107 are located on the same straight line, and the connection line is perpendicular to the conveying direction of the conveying device. The turnover mechanism 103 is used to realize the up-and-down turnover of the switch. It includes a clamping cylinder 1034 and a driving device I. The clamping cylinder 1034 can achieve vertical rotation, that is, the rotation axis of the clamping cylinder 1034 is parallel to the horizontal plane. In this embodiment, its rotation axis is parallel to the conveying direction of the conveying device. The driving device I is used to drive the clamping cylinder 1034 to rotate, so that the clamping cylinder 1034 can rotate between a first position and a second position.

At the same time, in order to improve the operation accuracy and reliability, limit blocks are provided at the first position and the second position for contacting the claws or the clamping cylinder 1034, so as to realize rotational limitation.

[0077] Since the switch has a small volume, in order to reduce the installation space and improve the structural compactness, the driving device I in this application includes a turnover cylinder 1031, a gear I 1033 and a rack I 1032. Refer to Figure 9 wherein, the gear I 1033 is arranged on the horizontal rotating shaft of the clamping cylinder 1034 and is rigidly connected to the clamping cylinder 1034.

When the rotating seat 2035 is in the third position, the material transfer groove 20351 is butted against the discharging end of the discharging mechanism II 201 and can accommodate the protection door to enter (input); when the rotating seat 2035 is in the fourth position, the protection door in the material transfer groove 20351 is parallel to the protection door installation angle of the multi-position socket on the conveying device. That is, at this time, the angle of the protection door on the rotating seat 2035 is the same as the installation angle. During the material transfer process of the material transfer manipulator II 202, there is no need to adjust the angle of the protection door anymore, and only horizontal movement is required. This improves the assembly accuracy and efficiency and reduces the manufacturing cost; in this application, the material transfer manipulator II 202 is also a biaxial manipulator.
