DETAILED DESCRIPTION

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] like Figures 1 to 7 As shown, the quality inspection equipment for lithium battery production line of the present invention comprises a detection part, a carrying mechanism, a feeding mechanism, a cleaning mechanism and a liquid supply mechanism;

[0041] The detection unit includes a gantry 2, a robotic arm 3 and an acquisition module arranged on the gantry 2. The robotic arm 3 is arranged on the gantry 2 and is used to flip the lithium battery. The robotic arm 3 uses a common three-axis robotic arm. The lithium battery is clamped by a clamp at the active end of the robotic arm 3 to control the flipping of the lithium battery, so that different surfaces of the lithium battery are facing the acquisition module, wherein the acquisition module includes an X-ray acquisition unit and a high-definition image acquisition unit. The X-ray acquisition unit is used to collect information on the internal conditions of the lithium battery, and the high-definition image acquisition unit is used to collect surface image information of the lithium battery.

[0042] When testing a lithium battery, the mechanical arm 3 clamps the lithium battery, turns the lithium battery over, and then uses the acquisition module to collect the internal conditions and external surface image information of the lithium battery to achieve the purpose of testing.

[0043] The bearing mechanism includes a bearing frame 1 , a conveyor belt 4 and a bearing plate 8 . The gantry frame 2 and the bearing plate 8 are both fixedly mounted on the bearing frame 1 . The bearing frame 1 provides installation and support for the gantry frame 2 and the bearing plate 8 .

[0044] The conveyor belt 4 is arranged in the carrier frame 1 and is used to convey the lithium battery through the gantry 2, wherein the conveyor belt 4 is a common crawler conveyor belt. When the lithium battery to be tested is located above the conveyor belt 4, the lithium battery is transported to the bottom of the gantry 2 through the conveyor belt 4. At this time, the lithium battery is clamped by the robotic arm 3 for easy detection.

[0045] The cleaning mechanism includes a support frame 7, a cleaning layer 14 and a wetting head 18. The support frame 7 is fixedly mounted on the upper end surface of the carrier plate 8. The internal channel of the support frame 7 is used for lithium batteries to pass through. During detection, the lithium batteries pass through the support frame 7 and enter the top of the conveyor belt 4.

[0046] The cleaning layer 14 is fixedly mounted on the inner wall of the support frame 7 , and the wetting head 18 is fixedly mounted on the inner wall of the support frame 7 , wherein the cleaning layer 14 is made of non-woven fabric on the outside, and a sponge is wrapped inside the non-woven fabric, and is evenly attached to the inner wall of the support frame 7 .

[0047] When the lithium battery passes through the interior of the support frame 7, the cleaning layer 14 wipes the outer wall of the lithium battery, thereby cleaning the surface of the lithium battery, so as to collect accurate high-definition image information and improve the detection efficiency of the outer surface of the lithium battery.

[0048] The liquid supply mechanism includes a storage box 21, a guide tube 22 and a control tube 17. The guide tube 22 is fixedly installed on the outer wall of the support frame 7. The control tube 17 is connected to one end of the guide tube 22. The other end of the guide tube 22 is fixedly connected to the wetting head 18. The wetting head 18 is made of a common sponge material. When the lithium battery enters the support frame 7, it first contacts the wetting head 18. During detection, the wetting head 18 is first wetted by a cleaning liquid. After the wetting head 18 absorbs the cleaning liquid, it contacts the surface of the lithium battery, so that the outer wall of the lithium battery is contaminated with the cleaning liquid. As the lithium battery contacts the cleaning layer 14, the cleaning effect of the lithium battery surface is improved to prevent stains from affecting the data accuracy of the lithium battery detection.

[0049] The storage box 21 is fixedly mounted on the outer wall of the support frame 7 and is used to provide cleaning liquid to the inner cavity of the guide tube 22. The inner cavity of the storage box 21 is used to store cleaning liquid. The discharge of the cleaning liquid in the guide tube 22 is controlled by the inner cavity pressure of the control tube 17. By adjusting the internal pressure of the control tube 17, the discharge of the cleaning liquid in the guide tube 22 is controlled, thereby achieving the wetting of the wetting head 18, so as to facilitate the application of cleaning liquid on the outer surface of the lithium battery.

[0050] The feeding mechanism is used to control the lithium battery to pass through the support frame 7. After the lithium battery passes through the support frame 7, the outer surface of the lithium battery is automatically cleaned, moved to the top of the conveyor belt 4, and transported to the bottom of the gantry 2 through the conveyor belt 4 for easy detection.

[0051] As a preferred embodiment of the present invention, a protective frame 6 is fixedly mounted on the upper end surface of the carrier plate 8, and the support frame 7 is located inside the protective frame 6, wherein the protective frame 6 wraps the support frame 7 and the storage box 21 to provide external protection.

[0052] A guide plate 5 is fixedly installed on the upper end surface of the supporting plate 8. The middle part of the guide plate 5 is bent inward, and one end extends to the upper end surface of the conveyor belt 4. Two guide plates 5 are symmetrically arranged. After the lithium battery passes through the support frame 7, it is guided into the conveyor belt 4 through the guide plate 5 to prevent the lithium battery from running off the track as much as possible.

[0053] The feeding mechanism comprises a top pressure plate 9, a transmission arm 10 and a control cylinder 13, wherein the control cylinder 13 is a common electric telescopic rod.

[0054] The control cylinder 13 is fixedly mounted on the outer wall of the support frame 1 , and one end of the transmission arm 10 is fixedly connected to the movable end of the control cylinder 13 , and the movement of the transmission arm 10 is controlled by telescoping the movable end of the control cylinder 13 .

[0055] The other end of the transmission arm 10 is fixedly connected to the outer wall of the top pressure plate 9 . When the transmission arm 10 moves, it drives the top pressure plate 9 to move synchronously, thereby pushing the lithium battery into the inner cavity of the support frame 7 .

[0056] The top pressure plate 9 is flush with the open end of the support frame 7. When the top pressure plate 9 pushes the lithium battery into the support frame 7, the cleaning layer 14 is scraped by the outer wall of the top pressure plate 9 to remove stains on the surface of the cleaning layer 14, thereby improving the cleaning effect of wiping the outer wall of the lithium battery next time.

[0057] In order to prevent the stains from flowing to the outer wall of the lithium battery when the top pressure plate 9 scrapes the cleaning layer 14, a boss is provided in the middle of the top pressure plate 9, so that when the top pressure plate 9 pushes the lithium battery, a gap is maintained between the outer wall of the lithium battery and the edge of the top pressure plate 9.

[0058] As a preferred embodiment of the present invention, a collecting bucket 19 is fixedly installed at the bottom of the support frame 7. A through hole connected to the collecting bucket 19 is opened at the bottom of the support frame 7. The stains generated by the top pressure plate 9 scraping the cleaning layer 14 flow into the inner cavity of the collecting bucket 19 to collect sewage.

[0059] Among them, an activated carbon adsorption layer is arranged inside the collecting bucket 19, which is used to adsorb dirt in the sewage inside the collecting bucket 19. A recovery pump 15 is fixedly installed on the outer wall of the storage box 21. The input end of the recovery pump 15 is connected to the inner cavity of the storage box 21. The input end of the recovery pump 15 is connected to the inner cavity of the collecting bucket 19. The cleaning liquid filtered in the collecting bucket 19 is recovered to the inner cavity of the storage box 21 through the recovery pump 15, thereby improving the use efficiency of the cleaning liquid and saving cleaning costs.

[0060] A discharge pump 16 is fixedly installed on the outer wall of the storage box 21. The input end of the discharge pump 16 is connected to the inner cavity of the storage box 21, and the output end of the discharge pump 16 is used to transport cleaning liquid to the inside of the guide pipe 22. After the discharge pump 16 absorbs the clean liquid inside the storage box 21, it discharges the cleaning liquid into the guide pipe 22 to achieve the wetting of the wetting head 18.

[0061] A control plug 29 is slidably installed on the inner wall of the material guide tube 22, and the outer wall of the control plug 29 is provided with rubber to achieve a sealed fit between the control plug 29 and the inner wall of the material guide tube 22, wherein the inner cavities of the material guide tube 22 and the control tube 17 are connected, and the control plug 29 is driven to slide by adjusting the air pressure in the inner cavity of the control tube 17.

[0062] An upper closing plate 27 is fixedly mounted on the inner wall of the material guide tube 22 , and a discharge hole is opened on the outer wall of the upper closing plate 27 , wherein the discharge pump 16 is used to discharge cleaning liquid into the chamber between the control plug 29 and the upper closing plate 27 .

[0063] A connecting rod 28 is fixedly installed on the bottom surface of the control plug 29, and an absorption layer 24 is provided on the outer wall of the connecting rod 28. The cleaning liquid discharged into the interior of the upper closing plate 27 is absorbed by the absorption layer 24. The absorption layer 24 is a common sponge. By setting the absorption layer 24, the cleaning liquid can be prevented from flowing naturally due to gravity.

[0064] When wetting the wetting head 18, the sliding control plug 29 drives the connecting rod 28 to slide until the absorption layer 24 contacts the upper closing plate 27, and squeezes the absorption layer 24 to discharge the cleaning liquid absorbed in the absorption layer 24 so that the wetting head 18 can absorb it, thereby achieving the effect of wetting the wetting head 18.

[0065] As a preferred embodiment of the present invention, a support plate 32 is fixedly installed on the outer wall of the connecting rod 28, and the sliding connecting rod 28 drives the support plate 32 to slide synchronously. The upper end surface of the support plate 32 is fixedly connected to the bottom of the absorption layer 24. When the connecting rod 28 slides upward, the absorption layer 24 is squeezed upward from the bottom to facilitate the absorption layer 24 to discharge the cleaning liquid.

[0066] An upper sealing piece 23 for sealing the upper closing plate 27 is slidably installed on the outer wall of the connecting rod 28. The bottom surface of the upper sealing piece 23 is in contact with the upper end surface of the absorption layer 24, and the bottom of the upper sealing piece 23 is connected to the upper end surface of the support plate 32 through an elastic member. When the connecting rod 28 slides upward, the upper closing plate 27 is closed by the upper sealing piece 23, and then when the absorption layer 24 is squeezed, the cleaning liquid in the absorption layer 24 can be prevented from flowing back.

[0067] When the control plug 29 slides downward, the connecting rod 28 drives the upper sealing piece 23 to separate from the upper closing plate 27. At this time, the upper closing plate 27 is turned on and the absorption layer 24 is restored. During this process, the absorption layer 24 absorbs the cleaning liquid above the upper closing plate 27 to facilitate the provision of cleaning liquid to the wetting head 18 next time.

[0068] A lower closing plate 26 is fixedly mounted on the inner wall of the guide tube 22. A through hole is provided in the lower closing plate 26, and the bottom of the lower closing plate 26 is in contact with the outer wall of the wetting head 18. A lower blocking piece 25 for blocking the lower closing plate 26 is fixedly mounted on the outer wall of the connecting rod 28. The sliding connecting rod 28 drives the lower blocking piece 25 to slide synchronously.

[0069] When the control plug 29 slides upward, the lower sealing plate 26 is closed to prevent the absorption layer 24 from absorbing the cleaning liquid in the wetting head 18. At the same time, the upper sealing plate 27 is turned on. When the absorption layer 24 recovers, it absorbs the cleaning liquid on the upper sealing plate 27.

[0070] When the control plug 29 slides downward, the lower closing plate 26 is turned on, and the absorbing layer 24 is compressed to drain water, so that the wetting head 18 can absorb the cleaning liquid. At the same time, the upper closing plate 27 is blocked to prevent the cleaning liquid from flowing back.

[0071] A bearing tube 20 is fixedly mounted on the outer wall of the bearing frame 1 , and an elastic tube 30 is fixedly mounted on the inner wall of the bearing tube 20 . A cavity is arranged inside the elastic tube 30 , wherein the elastic tube 30 is made of rubber.

[0072] The cavity inside the elastic tube 30 is connected to the inner cavity of the control tube 17 through a catheter. The elastic tube 30 is squeezed to increase the air pressure in the control tube 17. When the elastic tube 30 is released, the elastic tube 30 recovers. At this time, the air pressure in the control tube 17 is reduced, which is used to realize the sliding control of the control plug 29.

[0073] The control shaft 11 is fixedly mounted on the movable end of the control cylinder 13 , and when the movable end of the control cylinder 13 slides, the control shaft 11 is driven to slide.

[0074] The axis of the control shaft 11 coincides with the axis of the elastic tube 30. An extrusion boss 12 is fixedly mounted on the radial outer wall of the control shaft 11. When the control cylinder 13 drives the top pressure plate 9 to push the lithium battery, the control shaft 11 drives the extrusion boss 12 to synchronously extrude the elastic tube 30, thereby driving the control plug 29 to slide, thereby achieving the wetting of the wetting head 18 and maintaining the synchronization of the wetting of the wetting head 18 and the pushing of the lithium battery.

[0075] In order to facilitate the force for the elastic tube 30 to restore, an elastic strip 31 is fixedly installed on the inner wall of the elastic tube 30. A plurality of elastic strips 31 are provided, and a plurality of elastic strips 31 are evenly arranged in a ring shape along the axis of the elastic tube 30. By providing the elastic strip 31 as the internal support of the elastic tube 30, after the elastic tube 30 is pressed, the elastic force of the elastic strip 31 assists the elastic tube 30 to restore.

[0076] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
