Description

Technical Field

[0001] This invention belongs to the field of electrical component technology, specifically relating to batteries, and more particularly to a single-sided texturing device for battery cells and its working method. Background Technology

[0002] During the manufacturing process of solar cells, texturing is required on one side as needed. In related technologies, the solar cells are usually immersed in a chemical solution for texturing using a back-support method. This involves covering the non-textured side of the solar cell with a film or a rigid plate to prevent contamination of the non-textured side by the chemical solution. However, this method results in a tiny gap between the covering material and the non-textured side. This tiny gap is conducive to capillary action. As a result, the non-textured side of the solar cell often becomes contaminated due to capillary action of the texturing solution.

[0003] Therefore, due to the technical problem that the non-textured surface of the battery cell is contaminated by the chemical solution due to capillary action when the back side is supported during the single-sided texturing process, it is necessary to design a single-sided texturing device for battery cells and its working method.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0005] This disclosure provides at least one single-sided texturing device for battery cells and its working method.

[0006] In a first aspect, embodiments of this disclosure provide a single-sided texturing apparatus for battery cells, comprising:

[0007] Textile fabrication equipment, and

[0008] A support fixture, which carries battery cells, is moved to the texturing device, whereby the texturing device submerges the support fixture in a chemical solution to texturize the surface of the battery cells within the support fixture.

[0009] The load-bearing fixture includes: a housing;

[0010] The bottom surface of the housing has a groove for accommodating the battery cells, and a sealing ring is provided in the groove;

[0011] A support assembly is slidably disposed on the inner wall of the groove. The support assembly is located below the sealing ring, and the top surface of the support assembly supports the battery sheet.

[0012] During the process of the texturing device driving the supporting fixture to sink into the liquid, the liquid will push the supporting component upward, so that the battery cell moves closer to the sealing ring and presses against the sealing ring. The non-textured surface of the battery cell is in a sealed state with the top surface of the groove, and only the texturized surface of the battery cell contacts the liquid to perform texturing.

[0013] In one alternative embodiment, the support assembly includes: a support strip corresponding to the inner sidewall of the groove;

[0014] The housing has a cavity formed by a surrounding groove.

[0015] The inner wall of the groove is provided with several vertical strip-shaped holes to allow the groove to communicate with the cavity;

[0016] The cavity is provided with a lifting block that fits against the side wall with a strip-shaped hole;

[0017] The support bar contacts the inner wall of the corresponding groove, and the support bar is connected to the corresponding lifting block;

[0018] The top surface of the support bar supports the battery cells, and when the support bar rises, it causes the lifting block to move upward.

[0019] In one optional embodiment, a push plate is provided in the cavity, and the push plate is connected to the inner wall of the cavity by a spring;

[0020] The push plate is configured to push the liquid medicine in the chamber from the strip hole into the groove when the lifting block no longer blocks the push plate, so that the liquid medicine in the groove flows.

[0021] In one optional embodiment, when the texturing device drives the housing to sink into the liquid to the first depth, the sinking stops. At this time, the battery cell presses against the sealing ring, and the lifting block is located between the push plate and the strip hole.

[0022] As the fabrication device continues to lower the housing from the first depth, the lifting block gradually moves out from between the push plate and the strip hole. When the lifting block no longer blocks the push plate, the push plate pushes the liquid medicine in the chamber out of the strip hole into the groove, allowing the liquid medicine in the groove to flow.

[0023] In one alternative embodiment, the flocking device includes: a tank and a support plate;

[0024] The support plate is located in the groove, and the support plate has a through hole, the size of which is larger than the size of the groove;

[0025] The support plate is configured to receive the support tooling;

[0026] The tank contains a medicinal liquid.

[0027] In one alternative embodiment, the support plate is connected to a lifting mechanism, which includes: a mounting plate, a lead screw motor, and a pair of slide rails;

[0028] The slide rail is vertically mounted on the mounting plate, and a slider is provided on the slide rail;

[0029] The lead screw motor is mounted on the mounting plate and connected to the slider;

[0030] The slider is connected to the support plate via an extension block.

[0031] In one alternative embodiment, a feeding device is provided on one side of the tank and extends into the tank, the feeding device being configured to transport a bearing tooling onto a bearing plate inside the tank.

[0032] In one optional embodiment, a feeding station is provided at the head position of the feeding device, and a feeding device is provided on one side of the feeding station and a discharging device is provided on the other side.

[0033] The feeding device is configured to transport and place flower baskets containing the tooling.

[0034] The feeding device is configured to transport empty flower baskets.

[0035] In one optional embodiment, a conveying device is provided between the feeding device and the unloading device;

[0036] The conveying device includes: a two-axis sliding pair and a pair of clamping mechanisms;

[0037] The clamping mechanism is mounted on the two-axis sliding pair;

[0038] The gripping mechanism is configured to pick up the flower basket;

[0039] The two-axis sliding joint is configured to move the flower basket containing the carrying fixture to the loading station. The robot arm at the loading station is configured to move the carrying fixture to the feeding device. When one of the gripping mechanisms grips the flower basket containing the carrying fixture, the other gripping mechanism grips the empty flower basket at the loading station.

[0040] Secondly, this disclosure also provides a working method using the above-described single-sided texturing equipment for battery cells, comprising:

[0041] During the process of the texturing device driving the supporting fixture to sink into the liquid, the liquid will push the supporting component upward, so that the battery cell moves closer to the sealing ring and presses against the sealing ring. The non-textured surface of the battery cell is in a sealed state with the top surface of the groove, and only the texturized surface of the battery cell contacts the liquid to perform texturing.

[0042] The beneficial effects of this invention are as follows: This single-sided texturing equipment for battery cells includes a texturing device and a supporting fixture that carries a battery cell. After the supporting fixture moves to the texturing device, the texturing device drives the supporting fixture to sink into a chemical solution, so that the texturing surface of the battery cell is texturized in the supporting fixture. The supporting fixture includes a housing; the bottom surface of the housing has a groove for accommodating the battery cell, and a sealing ring is provided in the groove; a support component is slidably disposed on the inner wall of the groove, the support component is located below the sealing ring, and the top surface of the support component supports the battery cell. During the process of the texturing device driving the supporting fixture to sink into the chemical solution, the chemical solution pushes the support component upward, causing the battery cell to move closer to the sealing ring and press against the sealing ring. The non-textured surface of the battery cell is in a sealed state with the top surface of the groove, and only the texturing surface of the battery cell contacts the chemical solution for texturing, thereby achieving single-sided texturing of the battery cell by only one side of the battery cell contacting the chemical solution during the texturing process.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment.

[0063] During the manufacturing process of solar cells, texturing is required on one side as needed. In related technologies, the solar cells are immersed in a chemical solution for texturing on one side using a back-support method. However, the back-supported single-sided texturing process can lead to wetting and contamination on the back side due to capillary action.

[0064] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0065] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0066] like Figure 1 and Figure 2 As shown, at least one disclosed embodiment provides a single-sided texturing device for battery cells, including: a texturing device 1 and a supporting fixture 2, which carries battery cells. After the supporting fixture 2 moves to the texturing device 1, the texturing device 1 causes the supporting fixture 2 to sink into a chemical solution, so as to perform texturing on the texturing surface of the battery cells in the supporting fixture 2; wherein the supporting fixture 2 includes: a housing 21; the bottom surface of the housing 21 has a groove 211 for accommodating battery cells, and a sealing ring 212 is provided in the groove 211; the inner wall of the groove 211... A support component 22 is slidably mounted on the top. The support component 22 is located below the sealing ring 212, and the top surface of the support component 22 supports the battery cell. During the process of the texturing device 1 driving the carrying fixture 2 to sink into the liquid, the liquid pushes the support component 22 upward, causing the battery cell to move closer to the sealing ring 212 and press against the sealing ring 212. The non-textured surface of the battery cell is sealed with the top surface inside the groove 211. Only the texturized surface of the battery cell contacts the liquid for texturing, thus ensuring that only one side of the battery cell contacts the liquid during the texturing process, ensuring single-sided texturing of the battery cell.

[0067] In this embodiment, a gap is left between the sidewall of the battery cell and the inner sidewall of the groove 211 to facilitate the battery cell entering the groove 211.

[0068] In this embodiment, when the support fixture 2 is submerged in the liquid medicine, the buoyancy of the liquid medicine can cause the support component 22 to move the battery cell closer to and contact the sealing ring 212, thus preventing the liquid medicine from submerging the non-textured surface of the battery cell.

[0069] In this embodiment, when the battery cell approaches the sealing ring 212, the space between the battery cell and the top surface of the groove 211 decreases, and the pressure in this space increases. This increased positive pressure counteracts the upward suction of capillary action, thus preventing the liquid from affecting the non-textured surface of the battery cell.

[0070] like Figure 3As shown, in an optional embodiment, the support assembly 22 includes: a support strip 221 corresponding to the inner wall of the groove 211; a chamber 213 is provided around the groove 211 inside the housing 21; a plurality of vertical strip holes 214 are provided on the inner wall of the groove 211 to allow the groove 211 to communicate with the chamber 213; a lifting block 222 is provided in the chamber 213 to fit against the side wall with the strip holes 214; the support strip 221 contacts the inner wall of the corresponding groove 211 and is connected to the corresponding lifting block 222; the top surface of the support strip 221 supports the battery cell, and when the support strip 221 rises, it drives the lifting block 222 to move upward.

[0071] In this embodiment, the lifting block 222 can be in close contact with the side of the chamber 213 where the strip hole 214 is provided, so as to prevent the liquid medicine from entering the chamber 213 and entering the groove 211 through the part of the strip hole 214 located between the non-textured surface of the battery cell and the top surface of the groove 211, thus preventing the liquid medicine from contacting the top surface of the battery cell.

[0072] In this embodiment, the strip hole 214 can guide and limit the lifting and lowering of the support bar 221 and the lifting block 222.

[0073] like Figure 3 As shown, in an optional embodiment, a push plate 23 is provided in the chamber 213, and the push plate 23 is connected to the inner wall of the chamber 213 by a spring 24; the push plate 23 is configured to push the liquid medicine in the chamber 213 from the strip hole 214 into the groove 211 when the lifting block 222 no longer blocks the push plate 23, so that the liquid medicine in the groove 211 flows.

[0074] See Figure 5 and Figure 6 As shown, in this embodiment, when the battery cell 8 is texturized in the liquid medicine, bubbles may be generated. The bubbles will accumulate on the bottom surface of the battery cell. By pushing the liquid medicine in the chamber 213 into the water flow generated in the groove 211, the tiny bubbles attached to the texturized surface of the battery cell are dispersed, thereby avoiding the erosion of the battery cell surface caused by the accumulation and rupture of small bubbles due to long-term texturization.

[0075] In this embodiment, the push plate 23 can be positioned between the spring 24 and the lifting block 222. When the lifting block 222 abuts against the push plate 23, the push plate 23 is in a compressed state, so that when the lifting block 222 no longer obstructs the push plate 23, the push plate 23 can move toward the strip hole 214.

[0076] In one optional embodiment, when the texturing device 1 drives the housing 21 to sink into the liquid medicine to the first depth, the sinking stops. At this time, the battery cell presses against the sealing ring 212, and the lifting block 222 is located between the push plate 23 and the strip hole 214. When the texturing device 1 drives the housing 21 to continue sinking from the first depth, the lifting block 222 gradually moves out from between the push plate 23 and the strip hole 214. When the lifting block 222 no longer blocks the push plate 23, the push plate 23 pushes the liquid medicine in the chamber 213 out of the strip hole 214 into the groove 211, so that the liquid medicine in the groove 211 flows.

[0077] In this embodiment, the battery cells are texturized at the first depth.

[0078] In this embodiment, after the battery cell has been at the first depth for a certain period of time, the lead screw motor 15 drives the housing 21 to continue sinking. At this time, the push plate 23 pushes out the water flow generated by the liquid, which can carry the tiny air bubbles on the textured surface of the battery cell out of the bottom surface of the battery cell, ensuring the textured effect. Then the lead screw motor 15 stops working, and the housing 21 can stay at the second depth position for a certain period of time to continue textured.

[0079] In this embodiment, the second depth is greater than the first depth.

[0080] In this embodiment, when the housing 21 sinks from the first depth to the second depth, the sealing ring 212 is compressed and deformed to ensure the sealing effect.

[0081] like Figure 4 As shown, in one optional embodiment, the flocking device 1 includes: a tank 11 and a support plate 12; the support plate 12 is located inside the tank 11, and a through hole 13 is provided on the support plate 12, the size of the through hole 13 being larger than the size of the groove 211; the support plate 12 is configured to receive the support fixture 2; the tank 11 contains a medicinal liquid.

[0082] In this embodiment, when the support plate 12 supports the support fixture 2, the groove 211 is completely located in the through hole 13, and the through hole 13 can facilitate the contact of the liquid medicine with the battery cell.

[0083] like Figure 4 As shown, in one optional embodiment, the support plate 12 is connected to a lifting mechanism, which includes: a mounting plate 14, a lead screw motor 15, and a pair of slide rails 16; the slide rails 16 are vertically mounted on the mounting plate 14, and a slider 17 is mounted on the slide rails 16; the lead screw motor 15 is mounted on the mounting plate 14 and connected to the slider 17; the slider 17 is connected to the support plate 12 via an extension block 18.

[0084] In this embodiment, the lead screw motor 15 is electrically connected to the control module. The control module precisely controls the lifting distance of the slider 17 so that the housing 21 can accurately sink to the required depth.

[0085] like Figure 1 As shown, in one optional embodiment, a feeding device 3 is provided on one side of the tank 11 and the feeding device 3 extends into the tank 11. The feeding device 3 is configured to transport the bearing fixture 2 onto the bearing plate 12 inside the tank 11.

[0086] In this embodiment, the feeding device 3 may be composed of a conveyor belt, etc. The conveyor belt is driven by a motor, etc., and the motor is electrically connected to the control module.

[0087] like Figure 1 As shown, in one optional embodiment, a loading station 4 is provided at the head position of the feeding device 3, a loading device 5 is provided on one side of the loading station 4, and a unloading device 6 is provided on the other side; the loading device 5 is configured to transport a flower basket containing the carrying fixture 2; the unloading device 6 is configured to transport an empty flower basket.

[0088] In this embodiment, the feeding device 5 and the unloading device 6 are electrically connected to the control module. Both the feeding device 5 and the unloading device 6 can be composed of a conveyor belt, etc., and the motor used to drive the conveyor belt to rotate is electrically connected to the control module.

[0089] like Figure 1 As shown, in an optional embodiment, a conveying device 7 is provided between the loading device 5 and the unloading device 6; the conveying device 7 includes: a two-axis sliding joint 71 and a pair of clamping mechanisms 72; the clamping mechanisms 72 are disposed on the two-axis sliding joint 71; the clamping mechanisms 72 are configured to pick up the flower basket; the two-axis sliding joint 71 is configured to move the flower basket containing the carrying fixture 2 to the loading station 4, and the robot arm 41 provided at the loading station 4 is configured to move the carrying fixture 2 to the feeding device 3, and when one of the clamping mechanisms 72 clamps the flower basket containing the carrying fixture 2, the other clamping mechanism 72 clamps the empty flower basket at the loading station 4.

[0090] In this embodiment, the clamping mechanism 72 can use a gripper or other clamping method to clamp the flower basket, and the clamping mechanism 72 can be electrically connected to the control module.

[0091] In this embodiment, the two-axis sliding joint 71 can be electrically connected to the control module, and the robot arm 41 is also electrically connected to the control module.

[0092] In this embodiment, when one of the clamping mechanisms 72 clamps the flower basket containing the bearing fixture 2, the other clamping mechanism 72 clamps the empty flower basket at the loading station 4. When the two-axis moving pair 71 moves the empty flower basket to the unloading device 6, the flower basket containing the bearing fixture 2 moves to the loading station 4.

[0093] At least one other disclosed embodiment also provides a working method using the above-described single-sided texturing equipment for battery cells, including: during the process of the texturing device 1 driving the support fixture 2 to sink into the liquid, the liquid will push the support component 22 upward, so that the battery cell approaches and presses against the sealing ring 212, and the non-textured surface of the battery cell is in a sealed state with the top surface inside the groove 211, and only the texturing surface of the battery cell contacts the liquid to perform texturing.

[0094] In summary, this single-sided texturing equipment for battery cells includes: a texturing device 1 and a supporting fixture 2, which carries battery cells. After the supporting fixture 2 moves to the texturing device 1, the texturing device 1 causes the supporting fixture 2 to sink into the chemical solution, so as to perform texturing on the texturing surface of the battery cells in the supporting fixture 2. The supporting fixture 2 includes: a housing 21; the bottom surface of the housing 21 has a groove 211 for accommodating the battery cells, and a sealing ring 212 is provided in the groove 211; a sliding arrangement is provided on the inner wall of the groove 211. A support component 22 is provided, which is located below the sealing ring 212, and the top surface of the support component 22 supports the battery cell. During the process of the texturing device 1 driving the bearing fixture 2 to sink into the liquid, the liquid pushes the support component 22 upward, so that the battery cell moves closer to the sealing ring 212 and presses against the sealing ring 212. The non-textured surface of the battery cell is in a sealed state with the top surface of the groove 211. Only the texturized surface of the battery cell contacts the liquid for texturing, thereby realizing that only one side of the battery cell contacts the liquid during the texturing process, ensuring single-sided texturing of the battery cell.
