Description

Technical Field

[0001] The present application relates to the field of solar cell preparation, and in particular to an encapsulation device and an encapsulation system. Background Art

[0002] During the preparation of solar cells, insulating glue needs to be wrapped around the edge of the cell to form a glue layer. The insulating glue plays an insulating role during the electroplating process to prevent copper, tin and other electroplated metals from being plated onto the cell, causing a short circuit in the cell.

[0003] Usually, the edge of the battery cell is coated with glue by a roller in contact with the edge of the battery cell. This coating treatment method is prone to uneven coating, and the roller-type motion injection is also prone to cause battery cell fragments, edge collapse, corner chipping and other problems, affecting the yield of the battery cell. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a glue encapsulation device and a glue encapsulation system, which can improve the existing technical problems of uneven glue encapsulation and low battery yield.

[0005] In a first aspect, an embodiment of the present application provides a rubber coating device, which includes a carrying platform, a syringe, a first translation mechanism, an adsorption member and a flipping mechanism.

[0006] The carrying platform has a carrying surface for carrying the workpiece; the syringe is located above the carrying surface, and the outlet of the syringe faces the carrying surface; the first translation mechanism is connected to the syringe to drive the syringe to translate; the adsorption member is used to take and place the workpiece; the flipping mechanism is connected to the adsorption member, and the flipping mechanism is used to drive the adsorption member to flip so as to drive the adsorbed workpiece to turn over.

[0007] In the above implementation process, when the above-mentioned glue coating mechanism is used to coat the edge of a workpiece, such as a battery cell, since the syringe is located above the load-bearing surface and the outlet of the syringe is facing the load-bearing surface, the insulating glue can be evenly coated on the edge of the battery cell under the action of gravity, and hard contact between the syringe and the edge of the battery cell can be avoided, thereby avoiding damage to the edge of the battery cell during the glue coating process, thereby improving the yield rate of the battery cell after glue coating, and the problem of uneven glue layer after glue coating can be solved by controlling the glue spraying amount of the syringe. At the same time, since the edge of the battery includes the front edge area and the back edge area of ​​the battery cell, the flipping mechanism and the adsorption component are used in combination to flip the battery cell so that both the front edge area and the back edge area of ​​the battery cell can be coated, thereby improving the integrity and quality of the coating.

[0008] In a possible implementation, the flip mechanism includes: a lifting mechanism and a first rotation drive mechanism. The lifting mechanism has a lifting arm that can be lifted and lowered, the adsorbent is rotatably arranged on the lifting arm via a rotating shaft, the rotating shaft is perpendicular to the lifting direction of the lifting arm, the first rotation drive mechanism is arranged on the lifting arm, and the first rotation drive mechanism is transmission-connected with the adsorbent to drive the adsorbent to rotate around the rotating shaft.

[0009] In the above implementation process, the cooperation of the lifting mechanism and the first rotating drive mechanism has a compact structure and can realize the lifting and flipping of the adsorption part, which is beneficial to control the adsorption part to rise after adsorbing the workpiece to leave the bearing surface after the front edge area of ​​the workpiece is coated with glue, and then flip it to avoid interference between the bearing surface and the workpiece. Then, the lifting mechanism is used to lower the flipped workpiece and place it on the bearing surface, and the back edge area of ​​the workpiece is coated with glue to achieve the integrity of the coating, improve the efficiency of the coating, and save space.

[0010] In a possible implementation, the rubber encapsulation device further includes a second translation mechanism, the lifting mechanism is arranged on the second translation mechanism, and the second translation mechanism drives the lifting mechanism to translate.

[0011] In the above implementation process, the second translation mechanism is used to drive the lifting mechanism to translate, thereby realizing the translation of the adsorption component, so as to accurately control the position of the adsorption component according to actual needs.

[0012] In a possible implementation, the adsorption member has a hollow portion, and the size of the hollow portion is larger than the bearing surface, so that the adsorption member can be sleeved on the circumference of the bearing platform.

[0013] In the above implementation process, since the adsorption part can be sleeved on the circumference of the carrying platform, the adsorption part can be sleeved on the circumference of the carrying platform in advance. After the front edge area of ​​the workpiece is wrapped with rubber, the adsorption part is controlled to adsorb the back side of the workpiece and then rise to leave the carrying surface, and then flip it. At this time, the adsorption part is located above the workpiece, and then the flipped workpiece is lowered by the lifting mechanism and placed directly on the carrying surface. Under the above setting conditions, it is conducive to accurately control the position of the flipped workpiece on the carrying platform to avoid position offset between the two.

[0014] In a possible implementation manner, the bearing surface is provided with a plurality of vacuum adsorption holes arranged at intervals, and each vacuum adsorption hole is used to adsorb the workpiece.

[0015] In the above implementation process, the workpiece is adsorbed by vacuum adsorption, so that the workpiece can be stably fixed on the bearing surface, thereby avoiding displacement of the workpiece during the encapsulation process, resulting in uneven encapsulation.

[0016] In a possible implementation, the first translation mechanism includes: a frame, a first translation unit, and a second translation unit. The first translation unit is arranged on the frame; the second translation unit is arranged on the first translation unit, and the second translation unit is driven by the first translation unit to translate along a first direction; the syringe is arranged on the second translation unit, and the syringe is driven by the second translation unit to translate along a second direction, and the first direction and the second direction are perpendicular.

[0017] In the above implementation process, the first translation mechanism has a compact structure, and by utilizing the cooperation of the first translation unit and the second translation unit, the syringe can be translated along the first direction and the second direction, so as to accurately adjust the position of the syringe according to actual needs and enable the syringe to run along a preset path corresponding to the edge of the battery cell to perform glue encapsulation on the edge of the battery cell.

[0018] In a possible implementation, there are two first translation units, and opposite ends of the second translation unit are respectively disposed on the two first translation units, so that the opposite ends of the second translation unit move synchronously and in the same direction along the first direction.

[0019] In the above implementation process, the provision of two first translation units can make the operation of the second translation unit more stable and precise.

[0020] In a possible implementation, the encapsulation device further includes: a second rotation drive mechanism, an image acquisition mechanism, and a controller.

[0021] The second rotary drive mechanism is connected to the carrying platform to drive the carrying platform to rotate around its axis; the image acquisition mechanism is located above the carrying surface to acquire image information; the controller is respectively connected to the second rotary drive mechanism and the image acquisition mechanism signals, and the controller is used to control the second rotary drive mechanism to drive the carrying platform to rotate a preset angle through the acquired image information.

[0022] In the above implementation process, the second rotary drive mechanism, the image acquisition mechanism and the controller cooperate to achieve precise calibration and positioning of the workpiece, which is beneficial for the subsequent encapsulation, so that the edge of the corrected workpiece corresponds to the preset movement path of the syringe, thereby improving the uniformity and quality of the coating.

[0023] In a possible implementation, the first translation mechanism is electrically connected to the controller. When the controller determines that the supporting platform has rotated to a preset angle through the acquired image information, the controller controls the first translation mechanism to drive the syringe to translate.

[0024] In the above implementation process, since the first translation mechanism is electrically connected to the controller and utilizes the setting of the image acquisition mechanism, when the supporting platform is rotated to a preset angle, the controller can accurately control the first translation mechanism to drive the syringe to translate, thereby achieving corrective positioning and automatic and continuous production of rubber coating, thereby improving rubber coating efficiency.

[0025] In a second aspect, an embodiment of the present application provides a rubber coating system, which includes a loading mechanism arranged in sequence along the conveying direction of the workpiece, the rubber coating device provided in the first aspect of the present application, and a receiving platform.

[0026] Among them, the loading mechanism is used to place the workpiece on the glue coating device, the glue coating device is used to coat the edge of the workpiece with glue, and the receiving platform is used to receive the workpiece after the edge is coated with glue.

[0027] In the above implementation process, the cooperation of the feeding mechanism, the encapsulation device and the receiving platform is utilized to realize the continuous encapsulation processing of the workpiece, such as the battery cell, and effectively improve the encapsulation efficiency and productivity.

[0039] See also Figure 1 as well as Figure 2A rubber coating system 1000 includes a feeding mechanism 10, a rubber coating device 20, and a receiving platform 30 which are sequentially arranged along a conveying direction of a workpiece 40. Figure 1 as well as Figure 2 In the figure, X is used to indicate the conveying direction.

[0040] The loading mechanism 10 is used to place the workpiece 40 on the glue coating device 20 , the glue coating device 20 is used to coat the edge of the workpiece 40 with glue, and the receiving platform 30 is used to receive the workpiece 40 after the edge is coated with glue.

[0041] The shape of the workpiece 40 can be block-shaped or sheet-shaped. In the present embodiment, the workpiece 40 is a battery cell having a front side, a back side, and a side surface connecting the front side and the back side, wherein the front side has a front side center area and a front side edge area surrounding the front side center area, and the back side has a back side center area and a back side edge area surrounding the back side center area. The corresponding parts of the front side center area and the back side center area constitute the middle part of the battery cell, and the corresponding parts of the front side edge area, the back side edge area, and the side surface constitute the edge part of the battery cell, and the edge part is circumferentially arranged around the middle part.

[0042] Lagging refers to covering the edge with insulating glue.

[0043] See also Figure 1 as well as Figure 2 The loading mechanism 10 includes a loading platform 101 and a loading suction cup 102. The loading platform 101 can be a conveyor belt for transporting battery cells, or a conveyor platform for carrying battery cells. The loading suction cup 102 is used to absorb and transfer the workpiece 40 located on the loading platform 101 to the encapsulation device 20. It can be understood that the loading suction cup 102 can be provided with a mechanical arm 103 that can be translated and / or lifted, which is not described in detail here.

[0044] The number of the rubber encapsulation device 20 may be one or two. In this embodiment, the number of the rubber encapsulation device 20 is one.

[0045] The encapsulating device 20 includes a carrying platform 200 , a syringe 210 , a first translation mechanism, a suction member 230 and a flipping mechanism.

[0046] Among them, the carrying platform 200 has a carrying surface 201 for carrying the workpiece 40; the syringe 210 is located above the carrying surface 201, and the outlet of the syringe 210 faces the carrying surface 201; the first translation mechanism is connected to the syringe 210 to drive the syringe 210 to translate; the adsorption component 230 is used to take and place the workpiece 40; the flipping mechanism is connected to the adsorption component 230, and the flipping mechanism is used to drive the adsorption component 230 to flip to drive the adsorbed workpiece 40 to turn over.

[0047] When the above-mentioned glue coating mechanism is used to coat the edge of the battery cell, since the syringe 210 is located above the supporting surface 201 and the outlet of the syringe 210 is facing the supporting surface 201, the insulating glue can be evenly coated on the edge of the battery cell under the action of gravity, and at the same time, hard contact between the syringe 210 and the edge of the battery cell can be avoided, thereby avoiding damage to the edge of the battery cell during the glue coating process, thereby improving the yield rate of the battery cell after glue coating, and the problem of uneven glue layer after glue coating can be solved by controlling the glue spraying amount of the syringe 210. At the same time, since the edge of the battery includes the front edge area and the back edge area of ​​the battery cell, the flipping mechanism and the adsorption member 230 are used to turn the battery cell over, so that the front edge area and the back edge area of ​​the battery cell can be coated, thereby improving the coating quality.

[0048] The carrying surface 201 is a horizontally arranged plane, which can improve the stability of the battery cell placed on the carrying surface 201 .

[0049] Optionally, the bearing surface 201 is provided with a plurality of vacuum adsorption holes (not shown) arranged at intervals, and each vacuum adsorption hole is used to adsorb the workpiece 40. By providing the bearing surface 201 with vacuum adsorption holes, the bearing surface 201 can vacuum adsorb the workpiece 40, so that the workpiece 40 is stably fixed on the bearing surface 201, avoiding the problem of uneven encapsulation caused by displacement of the workpiece 40 during the encapsulation process.

[0050] In order to facilitate the control of the amount of insulating glue output by the syringe 210, optionally, the syringe 210 may be provided with a flow regulating tool (not shown in the figure), which can adjust the residual liquid in the syringe 210 according to actual needs, thereby adjusting the flow rate supplied by the syringe 210. In order to facilitate automatic flow regulation, the syringe 210 may be provided with a first controller (not shown in the figure). The flow regulating tool is, for example, a flow control valve, which is located at the outlet of the syringe 210. The first controller and the flow regulating valve can be electrically connected, so that the flow control valve changes the cross-sectional area of ​​the outlet according to the control of the first controller, thereby regulating the amount of insulating glue output by the syringe 210, so that the syringe 210 can evenly coat the edge of the battery cell with glue.

[0051] See also Figure 1 as well as Figure 2 The first translation mechanism includes: a frame 221, a first translation unit 222 and a second translation unit 223. The first translation unit 222 is arranged on the frame 221; the second translation unit 223 is arranged on the first translation unit 222, and the second translation unit 223 is driven by the first translation unit 222 to translate along a first direction; the syringe 210 is arranged on the second translation unit 223, and the syringe 210 is driven by the second translation unit 223 to translate along a second direction, and the first direction and the second direction are perpendicular. The second direction is parallel to the conveying direction of the workpiece 40.

[0052] In the above implementation process, the first translation mechanism has a compact structure, and by utilizing the cooperation of the first translation unit 222 and the second translation unit 223, the syringe 210 can be translated along the first direction and the second direction, so as to accurately adjust the position of the syringe 210 according to actual needs, and enable the syringe 210 to run along a preset path corresponding to the edge of the battery cell, so as to perform glue encapsulation on the edge of the battery cell.

[0053] Among them, the first translation unit 222 and the second translation unit 223 can both be screw structures, which is beneficial to improving the stability of the translation of the syringe 210. The specific settings can refer to the relevant technology and will not be described here.

[0054] The number of the first translation units 222 may be one or more, where the “multiple” here may be two, three, etc., for example, and the multiple first translation units 222 are arranged at intervals along the second direction.

[0055] In this embodiment, there are two first translation units 222, and opposite ends of the second translation unit 223 are respectively arranged on the two first translation units 222, so that the opposite ends of the second translation unit 223 move synchronously and in the same direction along the first direction. By setting two first translation units 222, the operation of the second translation unit 223 can be made more stable and accurate.

[0056] See also Figure 1 as well as Figure 2 The flipping mechanism includes: a lifting mechanism 241 and a first rotation driving mechanism 243 .

[0057] The lifting mechanism 241 has a lifting arm 242 that can be lifted and lowered. The adsorption component 230 is rotatably arranged on the lifting arm 242 via a rotating shaft 245. The rotating shaft 245 is perpendicular to the lifting direction of the lifting arm 242. The first rotating drive mechanism 243 is arranged on the lifting arm 242. The first rotating drive mechanism 243 is transmission-connected to the adsorption component 230 for driving the adsorption component 230 to rotate around the rotating shaft 245.

[0058] The above-mentioned flipping mechanism has a compact structure and can realize the lifting and flipping of the adsorption part 230. It is beneficial to control the adsorption part 230 to adsorb the workpiece 40 and then rise to leave the supporting surface 201 after the front edge area of ​​the workpiece 40 is coated with glue, and then flip it to avoid interference between the supporting surface 201 and the workpiece 40. Then, the lifting mechanism 241 is used to lower the flipped workpiece 40 and place it on the supporting surface 201, and the back edge area of ​​the workpiece 40 is coated with glue to achieve the integrity of the coating, improve the efficiency of the coating, and save the use space.

[0059] The lifting mechanism 241 includes but is not limited to an electric telescopic rod. In this embodiment, the lifting mechanism 241 is a vertically arranged telescopic cylinder.

[0060] The first rotation drive mechanism 243 is a motor. The transmission connection mode between the first rotation drive mechanism 243 and the adsorption member 230 includes but is not limited to a coaxial connection, and can also be a belt drive. Those skilled in the art can choose according to actual needs, which is not limited here.

[0061] The encapsulation device 20 further includes a second translation mechanism 250, and the lifting mechanism 241 is disposed on the second translation mechanism 250. The second translation mechanism 250 drives the lifting mechanism 241 to translate. The second translation mechanism 250 drives the lifting mechanism 241 to translate, thereby realizing the translation of the adsorption member 230, so as to accurately control the position of the adsorption member 230 according to actual needs.

[0062] Among them, the setting of the second translation mechanism 250 can refer to the first translation mechanism. At this time, the lifting mechanism 241 can move along the first direction and the second direction. In this embodiment, the second translation mechanism 250 drives the lifting mechanism 241 to reciprocate along the conveying direction of the workpiece 40. At this time, the setting of the second translation mechanism 250 can refer to the second translation unit 223, which will not be repeated here.

[0063] In order to ensure that the adsorption member 230 is located above the battery cell after flipping, so as to accurately place the workpiece 40 at a preset position on the carrying platform 200, optionally, the adsorption member 230 has a hollow portion 231, and the size of the hollow portion 231 is larger than the carrying surface 201, so that the adsorption member 230 can be mounted on the circumference of the carrying platform 200.

[0064] like Figure 1 As shown, the adsorption component 230 is a hollow frame. At this time, the adsorption component 230 can be pre-installed on the circumference of the carrying platform 200. After the front edge area of ​​the workpiece 40 is encapsulated with rubber, the adsorption component 230 is controlled to adsorb the back of the workpiece 40 and then rise to leave the carrying surface 201, and then flip it. At this time, the adsorption component 230 is located above the workpiece 40, and then the lifting mechanism 241 is used to lower the flipped workpiece 40 and directly place it on the carrying surface 201. Under the above-mentioned setting conditions, it is beneficial to accurately control the position of the flipped workpiece 40 on the carrying platform 200 to avoid positional offset between the two.

[0065] like Figure 3As shown, the adsorption component 230 is U-shaped and has an opening. At this time, the adsorption component 230 can be pre-mounted on the circumference of the supporting platform 200, and after the front edge area of ​​the workpiece 40 is coated with rubber, the adsorption component 230 is controlled to adsorb the back side of the workpiece 40 and then rise to leave the supporting surface 201, and then flip it over. At this time, the adsorption component 230 will be located above the workpiece 40; or the front edge area of ​​the workpiece 40 is first coated with rubber, and then the adsorption component 230 is mounted on the circumference of the supporting platform 200 by using the opening setting, and the adsorption component 230 is controlled to adsorb the back side of the workpiece 40 and then rise to leave the supporting surface 201, and then flip it over. At this time, the adsorption component 230 will also be located above the workpiece 40.

[0066] See also Figure 1 as well as Figure 2 In order to improve the uniformity and quality of the rubber coating, the rubber coating device 20 further includes: a second rotation driving mechanism 260, an image acquisition mechanism 270 and a second controller (not shown).

[0067] The second rotary drive mechanism 260 is connected to the carrier platform 200 to drive the carrier platform 200 to rotate around its axis; the image acquisition mechanism 270 is located above the carrier surface 201 to collect image information; the second controller is respectively connected to the second rotary drive mechanism 260 and the image acquisition mechanism 270 by signal, and the second controller is used to control the second rotary drive mechanism 260 to drive the carrier platform 200 to rotate a preset angle through the obtained image information. That is, the second rotary drive mechanism 260, the image acquisition mechanism 270 and the second controller cooperate to achieve accurate calibration and positioning of the workpiece 40, which is beneficial for the subsequent encapsulation, so that the edge of the corrected workpiece 40 corresponds to the preset moving path of the syringe 210, thereby improving the uniformity and quality of the coating.

[0068] The image acquisition mechanism 270 is, for example, a global camera.

[0069] Further optionally, the first translation mechanism is electrically connected to the second controller, and when the second controller determines that the carrier platform 200 rotates to a preset angle through the obtained image information, the second controller controls the first translation mechanism to drive the syringe 210 to translate. That is, since the first translation mechanism is electrically connected to the second controller, by using the setting of the image acquisition mechanism 270, it can be achieved that when the carrier platform 200 rotates to a preset angle, the second controller accurately controls the first translation mechanism to drive the syringe 210 to translate, thereby achieving correct positioning and automatic continuous production of rubber encapsulation, and further improving the efficiency of rubber encapsulation.

[0070] Furthermore, during actual use, since the image acquisition mechanism 270 is used to capture the edge of the battery cell, the movement of the first translation mechanism can be accurately controlled, the glue encapsulation accuracy is high, and the deviation of the glue encapsulation can be controlled to an accuracy of less than 0.05mm.

[0071] The receiving platform 30 may be a material unloading conveyor belt, and the adsorption member 230 is used to transfer the workpiece 40 after double-sided gluing to the receiving platform 30 .

[0072] In summary, when the glue encapsulation device provided in the present application is encapsulating the edge of a workpiece, such as a battery cell, it can not only avoid hard contact between the syringe and the edge of the battery cell, thereby avoiding damage to the edge of the battery cell during the glue encapsulation process and improving the yield rate of the battery cell after glue encapsulation, but also solve the problem of uneven glue layer after glue encapsulation by controlling the amount of glue sprayed by the syringe, and by using the cooperation of the flipping mechanism and the adsorption part, the battery cell can be flipped over, so that both the front edge area and the back edge area of ​​the battery cell can be coated, thereby improving the integrity and quality of the coating.

[0073] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
