[0083] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0084] See Figures 3-29This utility model provides a multi-socket assembly system for assembling a multi-socket 1'. The system includes a conveying device, specifically 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 assembly. During conveying, the length direction of the multi-socket 1' is parallel to the conveying direction of the conveying device.

[0085] The conveying device has multiple workstations along its conveying path. In this application, these workstations are arranged sequentially as follows: main loading workstation op10, switch assembly workstation op20, protective door assembly workstation op30, manual assembly workstation op40, lock unloading workstation op50, manual wire threading workstation op60, soldering workstation op70a, insertion testing workstation op70b, small panel assembly workstation op80, comprehensive testing workstation op90a, marking workstation op90b, and finished product unloading workstation op100.

[0086] The main feeding station op10 is used for feeding the upper cover 11' of the multi-position socket. During feeding, the upper cover 11' is equipped with a grounding terminal. The main feeding station op10 is the exposed end of the head of the conveying device.

[0087] A roller conveyor line is provided at one end of the main loading station OP10 to transport the material frames containing the top covers 11' and return the empty material frames. To facilitate operation and avoid misoperation, the roller conveyor line includes an infeed roller conveyor line and an outfeed roller conveyor line. The infeed roller conveyor line is used to transport the material frames filled with the top covers 11', i.e., full material frames. The workers at the main loading station OP10 can place the full material frames in a convenient loading position or directly perform material removal operations at the end of the infeed roller conveyor line, i.e., no manual handling is required. When all the top covers 11' in the material frames are loaded, they become empty material frames. The empty material frames are placed on the outfeed roller conveyor line for material frame return, and then the full material frames on the infeed roller conveyor line are operated again, and so on.

[0088] A switch assembly device 1 is provided on the switch assembly station op20. The switch assembly device 1 is used to assemble the switch 14' into the switch hole of the upper cover 11'.

[0089] A protective door assembly device 2 is provided on the protective door assembly station op30. The protective door assembly device 2 is used to assemble the protective door 15' onto the protective door mounting position of the upper cover 11'.

[0090] The manual assembly station op40 is an exposed conveyor device that allows for manual operation. Specifically, it is used to manually assemble the conductive sheet and the back cover 12' onto the upper cover 11'.

[0091] The locking and unloading station op50 is equipped with a first screw-locking device 31 and a semi-finished product unloading device 32. The first screw-locking device 31 is used to lock (fix) the rear cover 12' to the upper cover 11' with screws. The semi-finished product unloading device 32 is used to automatically move the multi-position socket to the fixture 2' for the next stage of assembly.

[0092] The manual wire threading station op60 is also an exposed conveying device that can be used for manual operation. Specifically, it is used to manually thread wires into the multi-position socket and insert the plug into the socket of the fixture 2' so that the wire terminals are connected to the terminals of the switch and the grounding terminal in the multi-position socket.

[0093] To improve work efficiency and reduce worker workload, a shelf and an automated loading robot are installed at the manual threading station OP60. The shelf is located directly in front of the conveyor, i.e., directly in front of the manual threading station OP60. The shelf has two pallets that can be raised and lowered synchronously. The position directly in front of the worker and easily accessible for material retrieval is defined as the retrieval position. The upper or lower end of the retrieval position is the waiting position. When one pallet is in the retrieval position, the other pallet is in the waiting position. During operation, the worker removes the material (wire) from the material box at the retrieval position and performs manual threading. In line operation, once all the material at the picking position is removed, resulting in an empty material frame, the two pallets simultaneously rise or fall. This moves the pallet (empty material frame) from the picking position to the waiting position, and correspondingly moves the pallet (full material frame) from the waiting position to the picking position. At this point, material can continue to be picked from the full material frame at the picking position. Simultaneously, the loading robot can remove the empty material frame from the waiting position and place the full material frame back into the waiting position, achieving automatic material replenishment. This process repeats continuously, greatly improving work efficiency and avoiding empty strokes and missed assembly caused by material shortages.

[0094] Soldering device 4 is provided on soldering station OP70A. Soldering device 4 is used to solder the electrical connection points in the multi-socket. There are multiple electrical connection points, namely five points A, B, C, D, and E. Point A is the connection point between the wire and the first terminal of the switch, point B is the connection point between the wire and the second terminal of the switch, point C is the connection point between the L-pole conductive piece and the third terminal of the switch, point D is the connection point between the N-pole conductive piece and the fourth terminal of the switch, and point E is the connection point between the ground wire of the wire and the grounding terminal of the multi-socket.

[0095] An interlocking test device 5 is provided on the interlocking test station op70b. The interlocking test device 5 is used to insert the probe 53 into the socket of the multi-position socket to detect the insertion resistance, and to test whether the protective door can be opened normally or whether the protective door is missing.

[0096] A small panel assembly device 6 is provided on the small panel assembly station op80. The small panel assembly device 6 is used to assemble the small panel 13' to the panel mounting position of the back cover 12' and fix it with screws.

A support cylinder 1055 is vertically arranged at the lower end of the bracket 1052. The output end is provided with a support plate, which is used to contact the bottom surface of the multi-socket on the workstation, thereby supporting the multi-socket; in this embodiment, the positioning support mechanism also includes a transverse module 1051, which is a stepper or servo drive device, including a lead screw whose length direction is parallel to the conveying direction of the conveying device. The bracket 1052 is set at the output end of the transverse module 1051, thereby achieving precise positioning in the horizontal direction and ensuring stable assembly and assembly accuracy.

[0105] See Figures 4-8 The switch assembly device 1 includes a discharge mechanism I 101, a tilting mechanism 103, a waiting trough 106, a transfer robot I 102, and a top-loading mechanism 107. The discharge mechanism I 101 is used for discharging the switch and includes a vibratory feeder. The tilting mechanism 103 is located between the discharge end of the discharge mechanism I 101 and the waiting trough 106. The tilting mechanism 103 is used to vertically flip the switch 14' at the discharge end of the discharge mechanism I 101 by 180 degrees and place it in the waiting trough 106. The vertical flipping is used to output the switch 14' from the discharge mechanism I 101. The switch plate with the terminal facing down is flipped so that the terminal facing up and placed in the waiting trough 106 to facilitate switch assembly. The transfer robot I 102 is used to transfer the switch 14' on the waiting trough 106 to the switch placement trough of the top material mechanism 107 located directly below the conveying device at this station. A top material cylinder 1071 is provided directly below the switch placement trough. The top material cylinder 1071 is used to lift the switch in the switch placement trough upward and press the switch from bottom to top into the switch hole of the multi-position socket, thereby realizing the assembly of the switch.

[0106] To improve assembly efficiency, in this application, the discharge end of the discharge mechanism I101, the tilting mechanism 103, the waiting trough 106, and the top-loading mechanism 107 are located on the same straight line, and the line connecting them is perpendicular to the conveying direction of the conveying device.

[0107] The flipping mechanism 103 is used to realize the up-and-down flipping 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 the first position and the second position.

[0108] When the clamping cylinder 1034 is in the first position, the clamping claw of the clamping cylinder 1034 is aligned with the discharge end of the discharge mechanism I 101 and can clamp the switch at the discharge end of the discharge mechanism I 101; when the clamping cylinder 1034 is in the second position, the clamping claw of the clamping cylinder 1034 is located directly above the waiting groove 106 and can put the flipped switch into the waiting groove 106. In both the first and second positions, the clamping cylinder 1034 is in a horizontal state.

[0109] In this embodiment, the clamping cylinder 1034 is a finger cylinder with two fingers that can move closer or further apart to clamp or release. Grippers are provided at the two output ends (fingers) of the finger cylinder. At the same time, in order to improve the running accuracy and reliability, limit blocks are provided at the first position and the second position to contact the grippers or the clamping cylinder 1034, thereby achieving rotational limit.

[0110] Due to the small size of the switch, in order to reduce installation space and improve structural compactness, the drive device I in this application includes a tilting cylinder 1031, a gear I 1033, and a rack I 1032. (See reference...) Figure 8 The gear I 1033 is mounted on the horizontal rotating shaft of the clamping cylinder 1034 and is rigidly connected to the clamping cylinder 1034. The rack I 1032 is vertically mounted and meshes with the gear I 1033. The tilting cylinder 1031 is vertically mounted and is located at the lower end of the rack I 1032 and is rigidly connected to the rack I 1032. It is used to drive the rack to move, thereby driving the gear I 1033 to rotate, and thus driving the clamping cylinder 1034 to reciprocate between the first position and the second position.

[0111] To ensure consistent quality and prevent the mixing of switches of different colors or with substandard colors, the switch assembly device 1 in this application further includes a detection sensor I 108. This sensor I 108 detects the color of the switches at the outlet of the switch dispensing mechanism 101. When a substandard color (non-designated extension) is detected, the transfer robot I 102 can move the substandard switch to the discharge port 109. The discharge port 109 is located between the waiting trough 106 and the conveying device, and is on the same straight line as the waiting trough 106 and the turning mechanism 103. To improve assembly efficiency, in this embodiment, the transfer robot I 102 is a dual-axis robot.

[0112] See Figures 9-12 The protective door assembly device 2 includes a material discharge mechanism II 201, a material transfer mechanism 203, and a material transfer robot II 202.

The material transfer mechanism 203 is located at the discharge end of the material discharge mechanism II 201 and can achieve horizontal rotation (i.e., the rotation axis is perpendicular to the horizontal plane) to adjust the protective door to the installation angle. The material transfer robot II 202 is used to transfer the protective door on the material transfer mechanism 203 to the protective door installation position of the multi-position socket.

[0113] The material transfer mechanism 203 includes a fixed base 2034, a rotating base 2035, and a drive device II. The rotating base 2035 is rotatably mounted on the fixed base 2034, and the rotation axis of the rotating base 2035 is perpendicular to the horizontal plane. The drive device II is used to drive the rotating base 2035 to rotate horizontally, and the rotating base 2035 is used to rotate between the third position and the fourth position. A transfer groove 20351 is provided on the upper surface of the rotary seat 2035 to accommodate the protective door. One end of the protective door is open. When the rotary seat 2035 is in the third position, the transfer groove 20351 is connected to the discharge end of the discharge mechanism II 201 and can accommodate the protective door. When the rotary seat 2035 is in the fourth position, the protective door in the transfer groove 20351 is parallel to the installation angle of the protective door of the multi-position socket on the conveying device. That is, at this time, the angle of the protective door on the rotary seat 2035 is consistent with the installation angle. During the material transfer process, the transfer robot II 202 does not need to adjust the angle of the protective door. It only needs to move horizontally, which improves the assembly accuracy and efficiency and reduces the manufacturing cost. In this application, the transfer robot II 202 is also a dual-axis robot.

The above-mentioned driving device II includes a gear II 2033, a rack II 2032 and a material transfer cylinder 2031. The gear II 2033 is set on the vertical rotating shaft of the rotary seat 2035. The rack II 2032 is set horizontally and meshes with the gear II 2033. The material transfer cylinder 2031 is also set horizontally. Its output end is connected to the rack II 2032 and is used to drive the rack II 2032 to move, thereby driving the rotary seat 2035 to rotate horizontally.

[0115] To improve the assembly efficiency of the protective doors, the material handling robot II 202 is equipped with multiple parallel grippers, which can assemble multiple protective doors simultaneously, preferably 2-3. In this application, there are two protective door assembly devices 2, which are arranged sequentially, which can further improve the assembly efficiency and ensure the time balance of each process.

The transfer robot Ⅲ 62 is used to transfer the small panel 13' on the waiting seat 63 to the multi-position socket on the conveying device of the station, thereby realizing the assembly of the small panel.

In the sixth position, the material placement plane 645a faces downward, and is located directly above the waiting base 63. A limiting baffle 6451 is provided at the end of the material placement plane 645a to limit the movement of the small panel.

[0119] In this application, the small panel assembly device 6 also includes a detection sensor II 65, which has a detection hole 6452 through it on the material placement plane 645a. When the flipping platform 645 is in the fifth position, the detection sensor II 65 is located directly below the detection hole 6452. It is used to detect whether there is a small panel 13' on the material placement plane to avoid empty stroke.

[0120] A placement surface is provided on the top surface of the waiting base 63 for placing the small panel 13' in a forward-facing position. The placement surface has a receiving groove 630 and a first positioning protrusion 631.
