Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] This embodiment aims to address the problem that the robotic arm requires repeated position adjustments to successfully grasp PIN pins, resulting in long processing times, complex structures, inconvenience, and hindering production efficiency. Please refer to [link to relevant documentation]. Figure 1 - Figure 5An automatic pin insertion machine for assembling automotive point light sources includes a workbench 100 and a control panel 400 disposed on one side of the workbench 100. The control panel 400 is used to control the movement of the overall device. A work panel 110 is disposed on the workbench 100 and is used to support the work panel 110. The assembly work is carried out on the work panel 110. A support frame 200 is fixedly installed on the work panel 110. A transparent cover 300 is embedded in the support frame 200. During operation, the working status during assembly can be observed through the transparent cover 300. Under the action of the transparent cover 300, the assembly work will not be affected by the outside world. The transparent cover 300 at one end is rotatably connected to the support frame 200. The transparent cover 300 is opened and closed on the support frame 200 to facilitate maintenance and the handling of parts.

[0029] Two support columns 500 are fixedly installed on the work panel 110. Each support column 500 is equipped with a second electric guide rail 510. A part-picking gripper 553 is installed on the second electric guide rail 510. The two support columns 500 are used to connect the second electric guide rail 510. Under the action of the second electric guide rail 510, the part-picking gripper 553 can slide left and right, which facilitates the adjustment of the position of the part-picking gripper 553.

[0030] A sliding rod 520 is slidably mounted on both second electric guide rails 510. The two ends of the sliding rod 520 are slidably connected to the second electric guide rails 510, so the sliding rod 520 can perform linear displacement. A third electric guide rail 530 is provided at one end of the sliding rod 520. The third electric guide rail 530 moves with the sliding rod 520. A slider 550 is slidably mounted on the third electric guide rail 530. The slider 550 can perform linear displacement about the third electric guide rail 530. The second electric guide rail 510, sliding rod 520, slider 550, and third electric guide rail 530 are all electric slide rails and are controlled by the control panel 400 to ensure that the sliding rod 520 and slider 550 can automatically slide to the designated position, which facilitates the electric control of this device.

[0031] A control head 560 is fixedly installed at one end of the slide head 550. A gear component 551 is rotatably installed on the control head 560. A lead screw 552 is threadedly connected to the middle of the gear component 551. The lead screw 552 is inserted and connected to the control head 560. The lower end of the lead screw 552 is connected to the part-picking gripper 553. A baffle 570 is also installed at the end of the control head 560 away from the slide head 550.

[0032] The control head 560 is connected to the slide head 550, so the slide head 550 and the control head 560 can move in multiple directions at the same time, which makes it easy to adjust the position of the picking gripper 553. It is highly flexible and has a high degree of automation. During the rotation of the gear component 551, it can drive the lead screw 552 to move up and down linearly. Therefore, the picking gripper 553 can also move up and down, which makes it easy to pick up and put down the PIN pin.

[0033] Among them, the lower end of the gear component 551 is connected to the gear set 554. The gear set 554 includes a motor and a belt mounted on the output pulley of the motor and a belt sleeved on the pulley. The gear component 551 is connected to one of the pulleys. Driven by the motor, the gear component 551 can rotate, which facilitates the automatic control of the up and down displacement of the picking gripper 553, resulting in a high degree of automation.

[0034] The work panel 110 is provided with two first electric guide rails 150, and a first operating plate 160 is provided on both first electric guide rails 150. The work panel 110 is also provided with a second operating plate 600, which is located above the first operating plate 160 and is slidably installed between the two first electric guide rails 150. The second operating plate 600 can slide about the first electric guide rails 150 to facilitate the adjustment of the position of the second operating plate 600. The two parts that need to be assembled for the automotive point light source are aligned with the first operating plate 160 and the second operating plate 600. The PIN pins used to connect the two parts are picked up by the part picker 553 and placed in the corresponding assembly holes of the two parts, thus completing the automatic pin insertion work.

[0035] This device has a simple structure and uses multiple driving components to drive different displacement parts, which facilitates multi-directional adjustment of the picking gripper 553 and has a high degree of automation.

[0036] Example 2

[0037] This embodiment aims to facilitate the solution of the problem of how to adjust the second operation panel 600 and the first operation panel 160. This embodiment is an improvement based on Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 - Figure 4 The work panel 110 is also equipped with a transmission group 700. One end of the transmission group 700 is connected to a belt group 710. The belt group 710 is located on the inner wall of the first electric guide rail 150, and the second operation plate 600 is located on the upper end of the belt group 710.

[0038] The transmission assembly 700 includes a motor, and the belt assembly 710 includes a pulley mounted on the output end of the motor and a belt sleeved on the two pulleys. When the motor starts, the belt can rotate. The two ends of the second operating plate 600 are attached to the belt of the belt assembly 710. Therefore, when the belt assembly 710 is working, the second operating plate 600 can be moved until it slides above the first operating plate 160 for easy control.

[0039] The working panel 110 is provided with a first fixed plate 111, a stabilizing plate 112 is fixedly installed on the first fixed plate 111, a stabilizing seat 113 is provided on the stabilizing plate 112, and side plates 114 are provided on both sides of the upper end of the stabilizing seat 113. A cam 115 is rotatably installed between the two side plates 114, and a pulley 116 is rotatably installed on the cam 115. The pulley 116 is slidably connected to the first operating plate 160 and the second operating plate 600.

[0040] The first fixed plate 111 is provided with multiple pulleys 116 connected thereto, which are located at the lower ends of the first operating plate 160 and the second operating plate 600 respectively. When the first operating plate 160 and the second operating plate 600 are displaced, the pulleys 116 can not only provide support, but also increase the stability of their displacement.

[0041] A limiting post 117 is fixedly installed on the stabilizing base 113. The limiting post 117 is located at the end of the cam 115 away from the pulley 116.

[0042] By setting the limiting post 117, it is easy to limit one end of the cam 115. Therefore, the cam 115 can only rotate in one direction. When it rotates, the height of the pulley 116 can be changed, which is convenient to adapt to the distance between the second operating plate 600 and the first operating plate 160, and has high adaptability.

[0043] Example 3

[0044] This embodiment aims to facilitate the solution of the problem of how the PIN pin feeding works in conjunction with the pick-up gripper 553. This embodiment is an improvement based on Embodiment 2. For details, please refer to [link to Embodiment 2]. Figure 2 - Figure 4 , Figure 7 The workbench 100 is also provided with a side frame 120 at one end, a housing 130 on the side frame 120, a vibrating feed plate 140 on the housing 130, and a guide belt 141 connected to one end of the vibrating feed plate 140.

[0045] A material distribution mechanism 170 is installed on the work panel 110. The material distribution mechanism 170 is located on the lower side of the part picking gripper 553. The end of the guide belt 141 away from the vibrating feeding plate 140 is attached to the material distribution mechanism 170.

[0046] The side frame 120 and the worktable 100 are an integral structure, used to place the vibratory feed tray 140. The PIN pins used for assembling automotive point light sources are placed in the vibratory feed tray 140. Through the operation of the vibratory feed tray 140, the PIN pins are orderly discharged from the guide belt 141 and finally picked up by the part grabber 553 and assembled onto the automotive point light source accessories.

[0047] The material distribution mechanism 170 includes a second fixed plate 171 fixed to the upper end of the working panel 110 and a fourth electric guide rail 172 mounted on the second fixed plate 171. A support frame 173 is slidably mounted on the fourth electric guide rail 172. Two slots 174 are provided on the support frame 173, and the slots 174 are adapted to the guide belt 141.

[0048] By setting up a material distribution mechanism 170, the PIN pins led out from the guide belt 141 are engaged in the slots 174 and located below the part-picking gripper 553, which facilitates the part-picking gripper 553 to pick up materials. By setting up a fourth electric guide rail 172 and a support frame 173, the support frame 173 can slide left and right about the fourth electric guide rail 172. When it slides to any end of the fourth electric guide rail 172, the slots 174 are connected to the guide belt 141. When it slides to the other end, another set of slots 174 are also connected to the guide belt 141. The part-picking gripper 553 picks up materials in the same position each time. Therefore, no calibration and adjustment are required when picking up materials, which saves time and increases assembly efficiency. The time for the support frame 173 to slide left and right is the same as the time for the part-picking gripper 553 to assemble, which is convenient for adapting to the feeding of the vibrating feeding plate 140 and facilitates the smoothness of the overall assembly.
