Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a cell bonding device and battery production equipment. Background Technology

[0002] With the advancement of technology, batteries are being used more and more widely, especially cylindrical lithium batteries. Cylindrical lithium batteries are widely used in laptops, digital cameras, lighting fixtures, toys, power tools, portable mobile energy sources and other fields. During the production of cylindrical lithium batteries, the cells need to be wound and glued to form a stable structure.

[0003] However, most existing battery cell adhesive application devices use a set of adhesive preparation mechanism and a set of adhesive application mechanism. The adhesive preparation mechanism pre-cuts the adhesive tape, and the adhesive application mechanism takes the tape from the adhesive preparation mechanism and then applies the tape to the battery cell. However, when the diameter of the battery cell increases and the required tape is longer, the pre-prepared tape is prone to being applied crookedly or at an angle, resulting in a low yield rate for battery cell adhesive application. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a battery cell adhesive bonding device.

[0008] The glue feeding mechanism includes a first linear drive, a first sliding member, and a glue clamping member. The first linear drive is disposed on the bracket. The first sliding member is slidably connected to the bracket and connected to the telescopic end of the first linear drive.

[0009] The adhesive pressing mechanism includes a second linear drive and an adhesive pressing assembly. The second linear drive is mounted on the bracket, and the adhesive pressing assembly is connected to the telescopic end of the second linear drive.

[0010] The glue-cutting mechanism includes a third linear drive and a glue-cutting assembly. The third linear drive is mounted on the bracket, and the glue-cutting assembly is connected to the telescopic end of the third linear drive.

[0011] In addition, the battery cell adhesive applicator according to this application may also have the following additional technical features:

[0013] In some embodiments of this application, the glue-cutting assembly includes a second connector and a glue-cutting component, the second connector being connected to the telescopic end of the third linear drive component, and the glue-cutting component being mounted on the second connector.

[0014] In some embodiments of this application, the battery cell adhesive applicator further includes a frame and a fourth linear drive, the fourth linear drive being disposed on the frame, the bracket being slidably connected to the frame and connected to the telescopic end of the fourth linear drive.

The conveying roller and the first tensioning roller group are rotatably mounted on the frame, and the second tensioning roller group is rotatably mounted on the first sliding member.

[0021] Compared to existing technologies, the beneficial effects of this application are:

[0022] This application discloses a battery cell adhesive applicator. When adhesive needs to be applied to a battery cell, the telescopic end of the first linear drive retracts, causing the first sliding member and the adhesive clamping member to rise and approach the battery cell. The adhesive held by the adhesive clamping member is positioned between the adhesive pressing assembly and the battery cell. After the adhesive is positioned between the adhesive pressing assembly and the battery cell, the telescopic end of the second linear drive extends, causing the adhesive pressing assembly to press the adhesive firmly against the circumferential wall of the battery cell. Then, the telescopic end of the first linear drive extends, causing the first sliding member and the adhesive clamping member to descend away from the battery cell and return to their initial extended state. Because the adhesive pressing assembly presses the adhesive firmly against the circumferential wall of the battery cell, the descent of the adhesive clamping member away from the battery cell allows the adhesive to be extracted. After the adhesive is extracted, the telescopic end of the third linear drive extends, causing the adhesive cutting assembly to approach the adhesive to cut it. After cutting the adhesive, the telescopic end of the third linear drive retracts, causing the adhesive cutting assembly to retract and return to its initial retracted state. After the adhesive cutting assembly retracts, the drive mechanism of the battery production equipment drives the cell to rotate, so that the adhesive is adhered to the circumferential wall of the cell under the pressing action of the adhesive pressing assembly. After the adhesion is completed, the telescopic end of the second linear drive retracts, causing the adhesive pressing assembly to retract and return to its initial retracted state. The cell adhesive application device provided in this application eliminates the need for pre-prepared adhesive, effectively improving the cell adhesive application yield.

[0041] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a cell adhesive applicator 100, which is mainly used in battery production equipment. The cell adhesive applicator 100 includes a support 110, an adhesive feeding mechanism 120, an adhesive pressing mechanism 130, and an adhesive cutting mechanism 140.

[0042] The glue feeding mechanism 120 includes a first linear drive 121, a first sliding member 122, and a glue clamping member 123. The first linear drive 121 is disposed on the bracket 110. The first sliding member 122 is slidably connected to the bracket 110 and connected to the telescopic end of the first linear drive 121. The glue clamping member 123 is disposed on the first sliding member 122 and is used to clamp the glue.

[0043] The adhesive pressing mechanism 130 includes a second linear drive 131 and an adhesive pressing assembly 132. The second linear drive 131 is mounted on the bracket 110, and the adhesive pressing assembly 132 is connected to the telescopic end of the second linear drive 131. The adhesive cutting mechanism 140 includes a third linear drive 141 and an adhesive cutting assembly 142. The third linear drive 141 is mounted on the bracket 110, and the adhesive cutting assembly 142 is connected to the telescopic end of the third linear drive 141.

[0044] The battery cell adhesive applicator 100 provided in the embodiments of this application has, in the initial state, the telescopic ends of the second linear drive member 131 and the third linear drive member 141 are both in a retracted state, so that the adhesive pressing assembly 132 and the adhesive cutting assembly 142 are both away from the battery cell, and the telescopic end of the first linear drive member 121 is in an extended state, so that the first sliding member 122 and the adhesive clamping member 123 descend away from the battery cell.

[0045] When adhesive needs to be applied to the battery cell, the telescopic end of the first linear drive 121 retracts, causing the first sliding member 122 and the adhesive clamping member 123 to rise and approach the battery cell. This places the adhesive held by the adhesive clamping member 123 between the adhesive pressing assembly 132 and the battery cell. After the adhesive is placed between the adhesive pressing assembly 132 and the battery cell, the telescopic end of the second linear drive 131 extends, causing the adhesive pressing assembly 132 to press the adhesive firmly onto the circumferential wall of the battery cell. Next, the telescopic end of the first linear drive 121 extends, causing the first sliding member 122 and the clamping member 123 to descend away from the battery cell and return to their initial extended state. Since the pressing assembly 132 presses the adhesive material firmly against the circumferential wall of the battery cell, the descent of the clamping member 123 away from the battery cell allows the adhesive material to be extracted. After the adhesive material is extracted, the telescopic end of the third linear drive 141 extends, causing the cutting assembly 142 to approach the adhesive material and cut it. After cutting the adhesive material, the telescopic end of the third linear drive 141 retracts, causing the cutting assembly 142 to retract and return to its initial retracted state. After the cutting assembly 142 retracts, the drive mechanism of the battery production equipment drives the battery cell to rotate, so that the adhesive material is adhered to the circumferential wall of the battery cell under the pressing action of the pressing assembly 132. After adhesion is completed, the telescopic end of the second linear drive 131 retracts, causing the pressing assembly 132 to retract and return to its initial retracted state. The battery cell adhesive applicator 100 provided in this application eliminates the need for pre-prepared adhesive, effectively improving the adhesive application yield of battery cells.

[0046] For example, the first linear drive 121, the second linear drive 131, and the third linear drive 141 can all be cylinders, hydraulic cylinders, or linear push rod motors, and the clamping part 123 can be a gripper.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the adhesive pressing assembly 132 includes a first connector 1321 and an adhesive pressing member 1322. The first connector 1321 is connected to the telescopic end of the second linear drive member 131, and the adhesive pressing member 1322 is rotatably mounted on the first connector 1321.

[0048] In this embodiment, by connecting the first connector 1321 to the telescopic end of the second linear drive 131, and rotatably mounting the adhesive pressing member 1322 on the first connector 1321, the adhesive pressing member 1322 can synchronously and stably extend and retract with the telescopic end of the second linear drive 131 via the first connector 1321, thereby achieving the function of pressing and releasing the adhesive. Simultaneously, the adhesive pressing member 1322 can rotate relative to the first connector 1321, so that under the rotational action of the adhesive pressing member 1322 and the battery cell, as well as the pressing action on the adhesive, the adhesive is adhered to the circumferential wall of the battery cell.

[0049] For example, the pressing component 1322 can be a pressing roller.

[0050] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the glue-cutting assembly 142 includes a second connector 1421 and a glue-cutting component 1422. The second connector 1421 is connected to the telescopic end of the third linear drive component 141, and the glue-cutting component 1422 is mounted on the second connector 1421.

[0051] In this embodiment, by connecting the second connector 1421 to the telescopic end of the third linear drive 141 and installing the cutting member 1422 on the second connector 1421, the cutting member 1422 can synchronously and stably extend and retract with the telescopic end of the third linear drive 141 through the second connector 1421, so as to achieve the function of cutting the rubber material and returning to the initial shrinkage state.

[0052] For example, the cutting component 1422 can be a cutting blade.

[0053] like Figure 1 and Figure 2 As shown, in one embodiment of this application, the battery cell adhesive applicator 100 further includes a frame 150 and a fourth linear drive 160. The fourth linear drive 160 is disposed on the frame 150. The bracket 110 is slidably connected to the frame 150 and connected to the telescopic end of the fourth linear drive 160.

[0054] This allows the bracket 110 to reciprocate linearly relative to the frame 150 on the frame 150, following the telescopic end of the fourth linear drive member 160. In the initial state, the bracket 110 and the glue feeding mechanism 120, glue pressing mechanism 130 and glue cutting mechanism 140 provided on the bracket 110 are moved away from the battery cell. When it is necessary to apply glue to the battery cell, the bracket 110 and the glue feeding mechanism 120, glue pressing mechanism 130 and glue cutting mechanism 140 provided on the bracket 110 are moved closer to the battery cell so that the glue can be pasted onto the circumferential wall of the battery cell.

[0055] For example, the fourth linear drive 160 can be a cylinder, a hydraulic cylinder, or a linear actuator motor.

[0056] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the glue feeding mechanism 120 further includes a conveying roller 124, a first tensioning roller group 125, and a second tensioning roller group 126. The conveying roller 124 and the first tensioning roller group 125 are rotatably mounted on the frame 150, and the second tensioning roller group 126 is rotatably mounted on the first sliding member 122. Thus, when the glue pressing assembly 132 presses the glue onto the circumferential wall of the battery cell and the glue clamping member 123 descends away from the battery cell, the glue can be extracted under the rotational action of the conveying roller 124, the first tensioning roller group 125, and the second tensioning roller group 126.

[0057] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the glue feeding mechanism 120 further includes a rotary drive 127, which is disposed on the frame 150, and the conveying roller 124 is connected to the rotating end of the rotary drive 127.

[0058] In this embodiment, the rotary drive 127 is mounted on the frame 150. By connecting the rotating end of the rotary drive 127 to the conveying roller 124, the conveying roller 124 is driven to rotate automatically, thereby automatically conveying the adhesive material and making it easier to extract the adhesive material.

[0059] For example, the rotary drive 127 can be a rotary motor.

[0060] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the battery cell adhesive applicator 100 further includes a first mounting frame 170, which is disposed on the frame 150. The first tension roller group 125 is rotatably disposed on the first mounting frame 170, and the rotary drive member 127 is disposed on the first mounting frame 170. Thus, the first tension roller group 125 and the rotary drive member 127 are stably mounted on the frame 150 via the first mounting frame 170.

[0061] like Figure 1 and Figure 2 As shown in the above embodiments of this application, the bracket 110 is provided with a first guide rail 111, the first sliding member 122 is slidably connected to the first guide rail 111, the frame 150 is provided with a second guide rail 151, and the bracket 110 is slidably connected to the second guide rail 151.

[0062] In this embodiment, by setting a first guide rail 111 on the bracket 110 and sliding the first slider 122 to the first guide rail 111, the first slider 122 follows the telescopic end of the first linear drive 121 and slides back and forth linearly along the first guide rail 111, playing a guiding role and effectively improving the accuracy of the reciprocating motion of the first slider 122.

[0063] Meanwhile, by setting a second guide rail 151 on the frame 150 and sliding the bracket 110 to the second guide rail 151, the second sliding member follows the telescopic end of the fourth linear drive member 160 to slide back and forth linearly along the second guide rail 151, playing a guiding role and effectively improving the accuracy of the reciprocating motion of the bracket 110.

[0064] like Figure 1 and Figure 2 As shown, in any of the above embodiments of this application, the battery cell adhesive applicator 100 further includes a second mounting bracket 180, which is disposed on the support 110. The second linear drive member 131 and the third linear drive member 141 are both disposed on the second mounting bracket 180. This ensures that the second linear drive member 131 and the third linear drive member 141 are stably mounted on the support 110 via the second mounting bracket 180, thereby guaranteeing the installation stability of the adhesive pressing assembly 132 and the adhesive cutting assembly 142.

[0065] This application also provides a battery production equipment, including the cell bonding device 100 described in the above embodiments.

[0066] The battery production equipment has the cell bonding device 100 in any of the above embodiments, and therefore has all the beneficial effects of the cell bonding device 100, which will not be described in detail here.
