Description

Technical Field

[0001] This utility model relates to the field of pressing pin technology, and in particular to a pressing pin device for a new energy vehicle motor controller. Background Technology

[0002] Before assembly, the motor controller of a new energy vehicle needs to be pressed in with pins. The internal pins are PCB circuit board fixing pins. If the pins are loose, the circuit board will shake inside the controller and collide with the controller, eventually causing the circuit board to short circuit and explode, resulting in the scrapping of the entire controller.

[0003] However, the existing pin pressing method involves manually placing the workpiece into the pressing equipment, then manually removing the pin and placing it into the pressing head. After pressing, the manual person holds the pin and gently pulls it upwards to check if the pin will come off or loosen. The process of feeding and placing the pin, as well as the inspection after pressing, are all done manually. The manual operation involves many steps, is tedious and complex, and has low processing efficiency. Furthermore, manual people cannot accurately and controllably inspect the pressing situation, thus failing to ensure the quality of the pressing.

[0004] Therefore, by developing a pin pressing device for a new energy vehicle motor controller, the feeding, insertion, and pressing of pins, as well as the post-pressing inspection, can be completed automatically, thereby improving processing efficiency, reducing the workload of workers, ensuring accurate and controllable inspection, and guaranteeing the quality of the pin pressing.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0027] like Figure 1-4As shown, a pin-pressing device for a new energy vehicle motor controller includes a frame 10, a pin-pressing station 100 on the frame 10, a detection station 200 on the rear side of the pin-pressing station 100, a pin feeding station 300 on one side of the pin-pressing station 100, a fixture plate 1 for placing workpieces on the pin-pressing station 100, a workpiece positioning and clamping mechanism 2 on the fixture plate 1, a pin-pressing device 3 above the fixture plate 1, and a fixture plate moving mechanism 4 on the frame 10 for driving the fixture plate 1 to move relative to the frame 10 between the pin-pressing station 100 and the detection station 200.

[0028] The pin feeding station 300 is provided with a pin feeding mechanism 5, and the detection station 200 is provided with a detection mechanism 6 and a pin transfer mechanism 7. The pin transfer mechanism 7 is used to transfer the pins from the pin feeding station 300 and place them into the pin installation position of the workpiece. The detection mechanism 6 is used to detect whether the pins are pressed tightly after being pressed.

[0029] Working principle: The pin feeding mechanism 5 enables the pins to continuously and orderly enter the pin feeding station 300. Initially, the fixture plate 1 is located at the pin pressing station 100.

[0030] Step 1 (Workpiece loading): The workpiece is manually placed into the fixture plate 1. The workpiece positioning and clamping mechanism 2 starts to clamp the workpiece. Then the fixture plate moving mechanism 4 moves to drive the fixture plate 1 to the inspection station 200.

[0031] Step 2 (Pin placement in workpiece): After the pin is in place, the pin transfer mechanism 7 is activated, clamps the pin and places it into the pin installation position of the workpiece, and then the pin transfer mechanism 7 drives the fixture plate 1 to reset.

[0032] Step 3 (Pin Pressing): Then the pin pressing device 3 operates to press the pin into the pin installation position of the workpiece, and then resets;

[0033] Step 4 (Pin Press-in Detection): Then the pin transfer mechanism 7 is activated, driving the fixture plate 1 to move to the detection station 200. After it is in place, the detection mechanism 6 is activated, clamping the pin and applying a set force to pull the pin upward (simulating the manual pin pulling detection method). If the pin is not pulled out, it is qualified; if the pin is pulled out, it is unqualified.

[0034] Step 5 (Workpiece Unloading): After the inspection is completed, the pin transfer mechanism 7 drives the fixture plate 1 to the pin pressing station 100. Then the workpiece positioning and clamping mechanism 2 is activated to release the clamp. The workpiece is then manually removed. No manual inspection is required after removal. The above steps are then repeated.

[0035] Compared with existing technologies, the above structure automates the feeding, insertion, and pressing of pins, as well as the inspection after pressing, thereby improving processing efficiency, reducing the workload of workers, ensuring accurate and reliable inspection, and guaranteeing the quality of the pressed pins.

[0036] Furthermore, such as Figure 1 , 2 As shown in Figures 1 and 3, the pin feeding mechanism 5 includes a storage bin 51, a vibratory feeder mechanism 52, and a linear vibration mechanism 53;

[0037] The discharge port of the storage bin 51 faces the vibrating plate mechanism 52. One end of the straight vibration track 531 of the straight vibration mechanism 53 is connected to the discharge port of the vibrating plate mechanism 52, and the other end is provided with a discharge hole 5312 that communicates with the straight vibration track 5311. The connection between the discharge hole 5312 and the straight vibration track 5311 is provided with an inclined surface 5313 that is inclined towards the discharge hole 5312.

[0038] In this embodiment, the pins in the storage bin 51 fall into the vibratory plate of the vibratory plate mechanism 52. Then, the vibratory plate mechanism 52 vibrates to make the pins enter the straight vibratory track 5311 of the straight vibratory track section 531 one by one in an orderly manner. Then, the straight vibratory mechanism 53 vibrates to transport the pins one by one. When the pin at the frontmost position enters the inclined surface 5313 from the straight vibratory track 5311 and falls into the dropping hole 5312, the pin changes from a horizontal state to a vertical state and is placed on the dropping hole 5312, realizing the automatic feeding of the pins, so as to facilitate the pin transfer mechanism 7 to pick up the pins from the pin feeding station 300.

[0039] Furthermore, such as Figure 2 , 3 As shown, an infrared sensor 8 is provided on the straight vibration track 5311 of the straight vibration track section 531, and a proximity sensor 9 is provided on one side of the material drop hole 5312.

[0040] In this embodiment, the pin conveying mechanism 7 is controlled to grab the pins by monitoring whether pins are continuously flowing into the linear vibration track 5311 by the infrared sensor 8 and whether pins are at the material drop hole 5312 by the proximity sensor 9, thus ensuring the normal feeding of pins.

[0041] Furthermore, such as Figure 1 , 2 As shown, the pin transfer mechanism 7 includes a first gripper 71 and a first gripper drive mechanism 72 for driving the first gripper 71 to move left and right and up and down.

[0042] In this embodiment, the first gripper drive mechanism 72 drives the first gripper 71 to move left and down to grab the pin above the material drop hole 5312. The first gripper 71 is driven to rise, move right and fall to place the pin into the workpiece at the detection station 200 according to its position, thereby realizing the automatic completion of the pin grabbing and placement into the workpiece pin installation position.

[0043] Furthermore, such as Figure 2 , 4 As shown, the detection mechanism 6 includes a second gripper 61 and a second gripper drive mechanism 62 for driving the second gripper 61 to move left and right and up and down.

[0044] In this embodiment, when the workpiece is pinned and moved to the inspection station 200, the second gripper drive mechanism 62 drives the second gripper 61 to move to the pin installation position on the workpiece, then moves down to grip and press the pin into the workpiece, and then pulls the pin upward by the upward pulling force and pulling time set by the program. During the process, the position of the pin is monitored by manual visual inspection or by detecting the position of the pin by an infrared sensor. For example, if the pin is pulled out after the set time, the infrared sensor receives a signal and automatically judges it as unqualified; if the pin is not pulled out after the set time, the infrared sensor does not receive a signal and automatically judges it as qualified. After the inspection is completed, the inspection mechanism 6 is reset.

[0045] Furthermore, such as Figure 2 , 4 As shown, the fixture plate moving mechanism 4 includes at least two slide rail pairs 41 and a slider driving cylinder 42 whose driving end is connected to the slider of the slide rail pair 41. The fixture plate 1 is slidably connected to the frame 10 through the slide rail pairs 41.

[0046] In this embodiment, the jig plate moving mechanism 4 drives a single jig plate 1 to move back and forth between the pin pressing station 100 and the inspection station 200, so as to realize the loading and pin pressing of the workpiece at the pin pressing station 100, and the pin insertion and inspection at the inspection station 200.

[0047] Furthermore, such as Figure 1 , 2 As shown in Figure 4, the workpiece positioning and clamping mechanism 2 includes multiple positioning rods 21 arranged around the outer perimeter of the workpiece, and multiple positioning pins 22 arranged on the positioning holes of the workpiece. A clamping cylinder 23 is also arranged at the position corresponding to the positioning pin 22.

[0048] In this embodiment, the workpiece is pre-positioned by the positioning rod 21, precisely positioned by the positioning pin 22, and pressed by the clamping cylinder 23, thereby firmly and securely fixing the workpiece on the fixture plate 1.

[0049] Furthermore, such as Figure 2 As shown, the frame 10 includes a stand 20 located on one side of the inspection station 200, and the inspection mechanism 6 and the pin transfer mechanism 7 are arranged vertically on the stand 20.

[0050] In this embodiment, the above structure reduces space occupation and reduces the operation time of the detection mechanism 6 or the pin transfer mechanism 7, thereby improving the operating efficiency of the device.

[0051] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
