[0030] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0031] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0032] Reference Figures 1 to 6 This utility model provides a battery cell pin insertion device, installed on a battery cell 7 production line, comprising a feeding assembly 1, a pin insertion assembly 2, and a ejector assembly 3. The feeding assembly 1 is used to transport support pins 6, specifically for feeding the support pins 6 and transferring them to the pin insertion assembly 2. The pin insertion assembly 2 is used to pick up the support pins 6 from the feeding assembly 1 and insert them into the center hole of the battery cell 7. The ejector assembly 3 is used to push the support pins 6, which are partially inserted into the center hole of the battery cell 7 by the pin insertion assembly 2, fully into the center hole.

[0033] Compared with the prior art, the battery cell pin insertion device provided by this utility model automatically feeds materials through a feeding mechanism, automatically inserts the support pin 6 through the pin insertion assembly 2, and fully pushes the support pin 6 into the center hole of the battery cell 7 through the ejector pin assembly 3. This forms a battery cell pin insertion device that automatically inserts the support pin 6 into the center hole of the battery cell 7, thereby improving the pin insertion efficiency and effectively solving the problem that the center hole of the battery cell 7 is prone to collapse during the circulation process.

[0034] Reference Figures 1 to 4Furthermore, the feeding assembly 1 includes a base 11, a material box 12, a feeding plate 13, and a moving drive component. The base 11 is the base of the feeding assembly 1, used to install and support the various components. It can be a table-type structure or a frame-type structure, etc. The material box 12 is fixedly set on the base 11, and there is a certain gap between the bottom of the material box 12 and the base 11. Specifically, a support column 111 is fixedly connected to the base 11, and the material box 12 is fixedly connected to the support column 111, so that the material box 12 is suspended above the base 11. The bottom of the material box 12 is provided with a discharge port 121, and the support pins 6 stored in the material box 12 can be output from the discharge port 121. The feeding plate 13 is slidably disposed on the base 11 to convey the support pin 6 output from the material box 12 outlet 121 to the bottom of the pin insertion assembly 2, so that the pin insertion assembly 2 can clamp the support pin 6. Specifically, the feeding plate 13 is slidably disposed on the base 11 and is located below the material box 12 and slides in contact with the bottom surface of the material box 12. The feeding plate 13 has a receiving groove 131 that is adapted to the shape and size of the support pin 6. When the receiving groove 131 and the outlet 121 are aligned, the support pin 6 falls from the outlet 121 into the receiving groove 131 under the action of gravity. Due to the limitation of the shape and size of the receiving groove 131, only one support pin 6 will fall onto the feeding plate 13 at a time, thereby realizing the material picking action of the feeding plate 13. At this time, the feeding plate 13 slides toward the pin insertion assembly 2 to realize the feeding action of the support pin 6. A moving drive component is mounted on the base 11 to drive the feeding plate 13 to move on the base 11. Specifically, the moving drive component is a first cylinder 14, which is a slide cylinder. The cylinder body of the first cylinder 14 is fixedly mounted on the base 11, and the feeding plate 13 is fixedly mounted on the slide of the first cylinder 14. When the piston rod of the first cylinder 14 extends, it drives the feeding plate 13 to move along the base 11 toward the needle insertion assembly 2 until the support needle 6 is transported to the needle picking position of the needle insertion assembly 2. When the piston rod of the first cylinder 14 retracts, it drives the feeding plate 13 to move away from the needle insertion assembly 2 until the outlet 121 and the receiving groove 131 are aligned again. At this time, the feeding plate 13 completes the picking up of material again, and the piston rod of the first cylinder 14 extends to drive the feeding plate 13 to perform the feeding action. The above actions are repeated to realize the automatic picking up and feeding of the support needle 6.

[0035] Reference Figure 2 Furthermore, a blower pipe 122 is provided at the bottom of the material box 12 near the pin assembly 2. The blower pipe 122 has several blow holes evenly distributed along its length, facing the feed plate 13. The blower pipe 122 can be connected to an air source (not shown in the figure). The air source supplies air to the blower pipe 122, and the air is blown out from the blow holes. During the feeding operation of the feed plate 13, the air blown out from the blow holes can blow off the floating dust on the surface of the support pin 6, preventing the support pin 6 from becoming dirty during the conveying process and affecting the quality of the battery cell 7.

[0036] Reference Figure 2 and Figure 4 Furthermore, a dust-collecting base plate 123 is provided at the bottom of the material box 12. The bottom of the dust-collecting base plate has several dust-collecting holes, through which dust and other impurities in the material box 12 can be discharged, thereby reducing the possibility of dirt getting on the support pins 6 inside the material box 12. Moreover, the dust-collecting base plate 123 is inclined towards the discharge port 121. Due to the inclined arrangement of the dust-collecting base plate 123, after the feeding plate 13 picks up the material, the support pins 6 in the material box 12 will roll towards the discharge port 121 under the action of gravity, further realizing automatic feeding.

[0037] Reference Figure 1 , Figure 2 and Figure 5 The pin insertion assembly 2 is used to pick up the support pin 6 from the feeding assembly 1 and insert the support pin 6 into the center hole of the cell 7. Specifically, the pin insertion assembly 2 includes a pin mounting plate 21, a first cell clamp 22 and a pin clamp 23. The pin mounting plate 21 is used to install the components of the pin insertion assembly 2. In this embodiment, a side plate 8 is also provided. The pin mounting plate 21 is fixedly connected to the side plate 8. In actual installation, the pin mounting plate 21 can also be fixed to the side plate of the cell 7 transfer production line. The first cell gripper 22 is slidably mounted vertically on the pin mounting plate 21. The pin mounting plate 21 has a vertically adjustable first gripper mounting plate 211 on which the first cell gripper 22 is mounted. Specifically, the pin mounting plate 21 is equipped with a second cylinder 221. In this embodiment, the second cylinder 221 is a sliding cylinder, fixedly mounted on the pin mounting plate 21, with the first gripper mounting plate 211 fixedly mounted on the sliding surface of the second cylinder 221. When the piston rod of the second cylinder 221 extends, it causes the first gripper mounting plate 211 to slide vertically downwards on the pin mounting plate 21, thereby lowering the first cell gripper 22. When the piston rod of the second cylinder 221 retracts, it causes the first gripper mounting plate 211 to slide vertically upwards on the pin mounting plate 21, thereby raising the first cell gripper 22. When the battery cell 7 on the production line flows to the pin insertion station (i.e., directly below the first battery cell gripper 22), the piston rod of the second cylinder 221 is extended until the first battery cell gripper 22 clamps the battery cell 7. Then, the piston rod of the second cylinder 221 is retracted, causing the battery cell 7 to rise to the pin insertion station. The pin insertion gripper 23 can move closer to or further away from the first battery cell gripper 22 in the horizontal direction. Specifically, a first transverse plate 213 that can move closer to or further away from the first battery cell gripper 22 in the horizontal direction is slidably provided on the pin insertion mounting plate 21. A first transverse drive assembly 4 is provided on the pin insertion mounting plate 21. The first transverse drive assembly 4 is connected to the first transverse plate 213 to drive the first transverse plate 213 to slide horizontally.

[0038] In this embodiment, the first cell gripper 22 is configured as a left gripper and a right gripper that can move closer to or further away from each other. When the left and right grippers are close together, they can grip the target object; when they are far apart, they can release the target object. The left and right grippers can be driven by a drive structure such as a double-slide linear module. The shape and size of the left and right grippers can be set according to the target object, and are not limited to a single one, as long as the above purpose can be achieved.

[0039] In this embodiment, the first transverse drive assembly 4 includes a first lead screw, a first lead screw nut, and a first motor. The output shaft of the first motor is connected to the first lead screw to drive it to rotate. The first lead screw nut is rotatably sleeved on the first lead screw and is fixedly connected to the first transverse plate 213. Starting the first motor drives the first lead screw to rotate, causing the first lead screw nut to move along the first lead screw, thereby achieving the sliding of the first transverse plate 213. A first transverse slide rail 214 is provided on the pin mounting plate 21. A first slider is fixedly connected to the first transverse slide rail 214 and slidably connected to it. When the first lead screw rotates and drives the first transverse plate 213 to move, the first slider slides on the first slide rail, achieving a sliding connection between the first transverse plate 213 and the pin mounting plate 21.

[0040] A second gripper mounting plate 212 is vertically movably mounted on the first transverse plate 213. Specifically, a third cylinder 231 is mounted on the first transverse plate 213. In this embodiment, the third cylinder 231 is a slide cylinder, which is fixedly connected to the first transverse plate 213. The second gripper mounting plate 212 is fixedly mounted on the slide of the third cylinder 231. When the piston rod of the third cylinder 231 extends, it causes the second gripper mounting plate 212 to slide vertically downward on the first transverse plate 213, thereby lowering the pin gripper 23. When the piston rod of the third cylinder 231 retracts, it causes the second gripper mounting plate 212 to slide vertically upward on the transverse plate, thereby raising the pin gripper 23.

[0041] When the feeding plate 13 conveys the support pin 6 to below the pin insertion gripper 23, the piston rod of the third cylinder 231 extends until the pin insertion gripper 23 grasps the support pin 6. Then, the piston rod of the third cylinder 231 retracts, causing the support pin 6 to rise to a position coaxial with the center hole of the battery cell 7 at the pin insertion station. At this time, the first motor is started, causing the first transverse plate 213 to slide, so that the support pin 6 on the pin insertion gripper 23 moves closer to the center hole of the battery cell 7 at the pin insertion station, and partially inserts the support pin 6 into the center hole of the battery cell 7. Then, the pin insertion gripper 23 releases the support pin 6 and returns to its original position. The piston rod of the second cylinder 221 extends, placing the battery cell 7 back onto the transfer production line. Then, the piston rod of the second cylinder 221 retracts, returning to the initial state, while the battery cell 7 follows the transfer production line to the next station.

[0042] Reference Figure 1 , Figure 2 and Figure 6 The ejector pin assembly 3 is used to fully push the support pin 6, which is partially inserted into the center hole of the battery cell 7 by the insertion pin assembly 2, into the center hole. Specifically, the ejector pin assembly 3 includes an ejector pin mounting plate 31, a second battery cell gripper 32, an ejector pin 33, and a fixture 34. The ejector pin mounting plate 31 is used to mount the components of the ejector pin assembly 3. In this embodiment, the ejector pin mounting plate 31 is fixedly connected to the side plate 8. In actual installation, the ejector pin mounting plate 31 can also be fixed to the side plate of the battery cell 7 transfer production line. The second battery cell gripper 32 can be raised and lowered on the ejector pin mounting plate 31 to grip the battery cell 7 to be ejected. The fixture 34 is used to mount the ejector pin 33. The ejector pin 33 is detachably fixed on the fixture 34. The fixture 34 is slidably mounted on the ejector pin mounting plate 31 and can move closer to or further away from the second battery cell gripper 32 along the ejector pin mounting plate 31.

[0043] The second cell gripper 32 is movably mounted on the ejector pin mounting plate 31. Specifically, a third gripper mounting plate 313 is movably mounted on the ejector pin mounting plate 31. The second cell gripper 32 is mounted on the third gripper mounting plate 313. A fourth cylinder 321 is mounted on the ejector pin mounting plate 31. In this embodiment, the fourth cylinder 321 is a slide cylinder, and the third gripper mounting plate 313 is fixedly mounted on the slide of the fourth cylinder 321. When the piston rod of the fourth cylinder 321 extends, it causes the third gripper mounting plate 313 to slide vertically downward on the ejector pin mounting plate 31, thereby lowering the second cell gripper 32. When the piston rod of the fourth cylinder 321 retracts, it causes the third gripper mounting plate 313 to slide vertically upward on the ejector pin mounting plate 31, thereby raising the second cell gripper 32. When the battery cell 7 to be ejected moves to the ejector station (i.e. directly below the second battery cell gripper 32) along the production line, the piston rod of the fourth cylinder 321 is extended until the second battery cell gripper 32 picks up the battery cell 7 to be ejected. Then the piston rod of the fourth cylinder 321 is retracted, which drives the battery cell 7 to be ejected to rise to the ejector station (at this time, the support pin 6 in the center hole of the battery cell 7 is coaxial with the ejector pin 33 on the fixture 34).

[0044] The fixture 34 is slidably disposed on the ejector pin mounting plate 31 and can move closer to or further away from the second cell clamp 32 along the ejector pin mounting plate 31. Specifically, a second transverse plate 311 is slidably disposed on the ejector pin mounting plate 31, and the second transverse plate 311 can move closer to or further away from the second cell clamp 32 in the horizontal direction. A second transverse drive assembly 5 is disposed on the ejector pin mounting plate 31, and the second transverse drive assembly 5 is connected to the second transverse plate 311 to drive the second transverse plate 311 to slide horizontally.

[0045] In this embodiment, the second transverse drive assembly 5 includes a second lead screw, a second lead screw nut, and a second motor. The output shaft of the second motor is connected to the second lead screw to drive its rotation. The second lead screw nut is rotatably sleeved on the second lead screw and is fixedly connected to the second transverse plate 311. Starting the first motor drives the second lead screw to rotate, causing the second lead screw nut to move along the second lead screw, thereby achieving the sliding of the second transverse plate 311. A second transverse slide rail 312 is provided on the ejector mounting plate 31. A second slider is fixedly connected to the second transverse plate 311 and slidably connected to the second transverse slide rail 312. When the second lead screw rotates and drives the second transverse plate 311 to move, the second slider slides on the second slide rail, achieving a sliding connection between the second transverse plate 311 and the ejector mounting plate 31.

[0046] When the second cell gripper 32 moves the cell 7 to be ejected to the ejector station, the second motor is started, driving the second transverse plate 311 to slide towards the cell 7, so that the ejector 33 moves closer to the support pin 6 on the center hole of the cell 7, and pushes the support pin 6 completely into the center hole of the cell 7, completing the insertion operation of the cell 7. Then, the second transverse plate 311 is driven to return to its original position away from the cell 7. The piston rod of the fourth cylinder 321 is driven to extend, placing the cell 7 back on the production line. Then, the piston rod of the second cylinder 221 is driven to retract, returning to the initial state, and the cell 7 follows the production line to the next process.

[0047] It should be noted that the structure and implementation principle of the pin clamp 23 and the second cell clamp 32 can be referred to the structure and implementation principle of the first cell clamp 22, and will not be elaborated here.
