Description

Technical Field

[0001] This invention relates to the field of power battery box manufacturing equipment technology, and in particular to a device for attaching a buffer pad to a battery box product. Background Technology

[0002] With the rise of new energy vehicles, the top cover of the power battery pack is increasingly made of lightweight composite materials, which are thin, light, and strong. However, as the range of new energy vehicles increases and the size of the battery packs increases, the rigidity of composite material battery box covers and some thin-walled metal covers is insufficient, which can cause abnormal noises due to vehicle vibration during driving. By attaching a buffer pad, a soft buffer layer is formed between the battery box cover and the battery module, which can effectively prevent the generation of such abnormal noises.

[0003] Traditional cushioning pads are applied manually. Workers peel off the release paper from the back of the cushioning pad and apply it from one side to the other along the etched lines on the product. The application process uses hand pressure or rollers to press the pad to ensure that the adhesive layer adheres completely to the product. This method is not only inefficient, but also makes it difficult to guarantee the accuracy of the application. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, the present invention provides the following technical solution:

[0005] A battery box product cushioning pad pasting device includes a frame, a guide rail and a first cylinder in the middle of the frame, the guide rail and the first cylinder being parallel to each other, multiple sliders slidably connected on the guide rail, a cushioning pad positioning plate fixedly connected to the top of the sliders, a first piston rod at the top of the first cylinder, the top of the first piston rod being fixedly connected to the bottom of the cushioning pad positioning plate, a pressure frame above the cushioning pad positioning plate, multiple limiting blocks fixedly connected around the perimeter of the pressure frame, multiple guide posts vertically arranged on the inner side of the frame, a flange at the middle of the guide posts, a cover plate at the top of the frame, the flange being fixedly connected to the cover plate, a second cylinder vertically arranged at the top center of the frame, a second piston rod at the bottom of the second cylinder, the bottom end of the second piston rod being fixedly connected to the pressure frame, and a control box and a pressure regulating valve on the side of the frame.

[0006] Furthermore, the edge of the buffer pad positioning plate is provided with a product positioning block, and the end and middle of the buffer pad positioning plate are both provided with through holes. A buffer pad positioning rail is inserted into the end through hole, and a buffer block is inserted into the middle through hole.

[0007] Furthermore, the end and middle through holes of the buffer pad positioning plate are both rectangular in shape.

[0008] Furthermore, the guide rail is a double-rail guide rail, with the first cylinder located in the center of the guide rail, and each guide rail is provided with at least two sliders.

[0009] Furthermore, a pad is provided between the buffer pad positioning plate and the buffer pad positioning rail.

[0010] Furthermore, the number of guide pillars is four, arranged in a matrix.

[0011] Furthermore, a gas spring is provided on each side of the first cylinder.

[0012] Furthermore, a lighting fixture is also provided below the frame.

[0013] The beneficial effects of this invention are as follows: the technical solution uses a cushioning pad positioning plate pasting device to position the cushioning pad, making the attachment position of the cushioning pad more accurate; the pasting device is designed with multiple cushioning pad positioning grooves, enabling multiple cushioning pads to be pasted at one time, greatly improving the pasting efficiency and saving labor; the downward pressure is evenly distributed on the product by using a cylinder and guide column to press down, and the downward pressure is accurately controlled by a pneumatic pressure regulating valve, which can very smoothly achieve the pasting of the cushioning pad.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, a battery box product cushioning pad pasting device includes a frame 10. A guide rail 11 and a first cylinder 12 are located in the middle of the frame 10. The guide rail 11 and the first cylinder 12 are parallel to each other. Multiple sliders 13 are slidably connected to the guide rail 11. A cushioning pad positioning plate 20 is fixedly connected to the top of each slider 13. A first piston rod is located at the top of the first cylinder 12. The top of the first piston rod is fixedly connected to the bottom of the cushioning pad positioning plate 20. A pressure frame 30 is located above the cushioning pad positioning plate 20. Multiple limiting blocks 31 are fixedly connected to the periphery of the pressure frame 30. Multiple guide posts 32 are vertically arranged on the inner side of the frame of the pressure frame 30. A flange is provided in the middle of the guide post 32. A cover plate 33 is provided on the top of the frame 10. The flange is fixedly connected to the cover plate 33. A second cylinder 34 is vertically arranged at the top center of the frame 10. A second piston rod is provided at the bottom of the second cylinder 34. The bottom end of the second piston rod is fixedly connected to the pressure frame 30. A control box 14 and a pressure regulating valve 15 are provided on the side of the frame 10.

[0023] like Figure 3 , Figure 4 , Figure 5 As shown, the edge of the buffer pad positioning plate 20 is provided with a product positioning block 21. The buffer pad positioning plate 20 has through holes 201 on the left and right sides and in the middle. Buffer pad positioning rails 22 are inserted into the through holes 201 on the left and right sides. Buffer blocks 23 are inserted into the through hole 201 in the middle. The bottom of each through hole 201 is provided with a base plate 24. The base plate 24 has a groove with the same shape and size as the through hole 201. The bottom of the buffer pad positioning rails 22 and the buffer blocks 23 are both provided with round holes. Springs 25 are provided in the round holes. The springs 25 are elastically connected to the bottom of the grooves.

[0024] When implementing this technical solution, the first cylinder 12 first slides the buffer pad positioning plate 20 on the device out of the frame 10 along the guide rail 11.

[0025] Then place the buffer pad 29 with the backing release paper peeled off between the buffer pad positioning groove formed by the buffer pad positioning bar 22 and the buffer block 23, with the adhesive side facing up.

[0026] Then, place the battery box with the side of the product attached to the buffer pad facing down along the product positioning block 21 on the buffer pad positioning plate 20; since the buffer pad positioning bar 22 and buffer block 23 on the buffer pad positioning plate 20 are higher than the buffer pad 29, the product falls on the buffer pad positioning bar 22 and does not contact the foam adhesive surface.

[0027] Next, press the switch on the control box 14, and the first cylinder 12 will send the buffer pad positioning plate 20 into the interior of the frame 10 along the guide rail 11;

[0028] After the buffer pad positioning plate 20 is in place, the second cylinder 34 drives the pressure frame 30 to press down; the pressure frame 30 contacts the product and, under the action of the second cylinder 34, continues to drive the buffer pad positioning rail 22 and the buffer block 23 to press down into the groove on the bottom plate 24 until the rubber surface of the buffer pad 29 contacts and presses firmly against the surface of the battery box; the pressing stops after the compression amount designed for the foam buffer pad 29 is reached.

[0029] After the pressure frame 30 is pressed down to the bottom and held for 10 seconds, the pressure frame 30 automatically rises. After rising to the top, the buffer pad positioning plate 20 is pushed by the first cylinder 12 to slide out of the frame 10 along the guide rail 11; finally, the battery box product is taken out.

[0030] In this device, the thickness of the buffer pad positioning bar 22 is designed to be greater than that of the buffer pad 29. After the release paper of the buffer pad 29 is removed, the buffer pad 29 is placed in the groove of the buffer pad positioning bar 22, and the height of the buffer pad 29 is lower than that of the buffer pad positioning bar 22 and the buffer block 23. At this time, the battery box product is guided and positioned on the buffer pad positioning plate 20 by the product positioning block 21 on the buffer pad positioning plate 20. The product is supported above the buffer pad 29 by the buffer pad positioning bar 22, and there is a certain gap between the product and the buffer pad 29 so that they are not in contact. When the product slides into the frame 10 along with the buffer pad positioning plate 20, the device receives the positioning signal of the buffer pad positioning plate 20. The pressure frame 30 is pushed down along the guide post by the second cylinder 34. The pressure frame 30 first contacts the product and then gradually presses down. The springs in the buffer pad positioning bar 22 and the buffer block 23 are compressed and pressed to the lowest position under the guidance of the guide screw, which limits the second cylinder 34 from continuing to press down. At this time, the compression of the buffer pad 29 is compressed to the designed compression amount. After a certain pressure holding time, the second cylinder 34 drives the pressure frame 30 to rise automatically, and the buffer pad positioning plate 20 slides out, so that the buffer pad 29 and the battery box product can be pressed and pasted together at one time.

[0031] like Figure 4 As shown, preferably, the through holes on the left and right sides and in the middle of the buffer pad positioning plate 20 are rectangular in shape, which makes the processing easier and simpler.

[0032] like Figure 1 , Figure 5As shown, the guide rail 11 is a double-rail guide rail. The first cylinder 12 is located in the center of the guide rail 11. Each guide rail 11 is provided with at least two sliders 13. The double-rail design makes the structure simpler while ensuring stable sliding. The first cylinder 12 is located in the center of the double guide rail, so that the pushing and pulling force of the cylinder is applied more evenly to the buffer pad positioning plate 20, making the sliding smoother. In order to ensure the stable sliding of the buffer pad positioning plate 20, at least two sliders are provided on each guide rail. The fewer the number of sliders, the lower the frictional resistance and the lower the manufacturing cost.

[0033] Preferably, such as Figure 1 , Figure 3 As shown, a pad 26 is also provided between the buffer pad positioning plate 20 and the buffer pad positioning rail 22. Since the part that is frequently in contact with the product is a vulnerable part, the pad 26 can prevent the product from directly contacting the buffer pad positioning plate 20, reduce its wear, and the pad 26 is more convenient to replace than the buffer pad positioning plate 20.

[0034] Preferably, the number of guide posts 32 is four, arranged in a matrix. This arrangement ensures that the vertical displacement of the pressure frame 30 is more stable, the downward pressure is more uniform, and the buffer pad 29 is more smoothly adhered to the product surface.

[0035] like Figure 5 As shown, a gas spring 16 is provided on each side of the first cylinder 12, which can play a buffering role, reduce the impact and vibration of the buffer pad positioning plate 20 and the first cylinder 12, and improve the service life of the device components.

[0036] Preferably, such as Figure 6 As shown, a lighting lamp 17 is also provided below the frame 10. Since the internal space of the device is small, the lighting lamp 17 can provide lighting convenience for the later maintenance and repair of the device.

[0037] This technical solution uses a device to position the buffer pad 29, making the attachment position of the buffer pad 29 more accurate. The device is designed with multiple buffer pad positioning grooves, which can achieve the simultaneous attachment of multiple buffer pads 29, greatly improving the attachment efficiency and saving manual time. The downward pressure is evenly distributed on the product by using a cylinder and guide column, and the downward pressure is accurately controlled by the air pressure regulating valve 15, which can achieve the attachment of the buffer pad very smoothly.

[0038] This invention employs a slide rail and slide table method to position the product and the buffer pad on the outside of the frame, and then presses and adheres the buffer pad inside the device. The buffer pad positioning plate is designed with a buffer pad positioning rail, which is 24mm higher than the plane where the buffer pad is placed. This allows for effective positioning and adhesion of buffer pads thinner than 24mm. For buffer pads thicker than 24mm, a corresponding height positioning rail can be designed, broadening the applicability of the device.
