Description

Technical Field

[0001] The utility model relates to the technical field of battery processing equipment, in particular to an auxiliary device for pasting insulating sheets. Background Art

[0002] During the production and processing of batteries, it is necessary to stick several insulating sheets at intervals on the bottom of the battery module box. The current common practice is that the operator uses the positioning holes on the horizontal protrusions on both sides of the box as a reference, visually inspects the distance between the insulating sheet and the positioning holes, thereby determining the location of the insulating sheet pasting area, and then sticks the insulating sheet on the visually inspected pasting area. It can be seen that this practice is highly dependent on the operator's technical level, making it difficult to ensure the consistency of the pasting effect. In addition, the pasting accuracy is insufficient, and it is very easy for the insulating sheet to be pasted in the wrong position or crookedly. Utility Model Content

[0003] The purpose of the utility model is to solve the technical problems that the existing technology uses manual visual inspection of the insulating sheet pasting position, which makes it difficult to ensure the consistency of the insulating sheet pasting effect and is easy to paste the insulating sheet in the wrong position or crookedly, and provides an insulating sheet pasting auxiliary device.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An insulating sheet pasting auxiliary device, comprising:

[0006] Bracket;

[0007] baffles, the number of which is at least two, and the baffles are spaced apart and arranged on the bracket;

[0008] The connecting member is provided on at least one of the bracket and the baffle, and the connecting member can be connected to the battery module box.

[0009] The side wall of the baffle abuts the edge of the insulating sheet pasting area, and can be in abutment along the entire length of the insulating sheet or only partially abutted, as long as it can guide the pasting of the insulating sheet; the number of baffles can directly match the number of insulating sheets, so that the pasting of all insulating sheets can be guided in one disassembly and assembly; the number of baffles can be less than the number of insulating sheets, so that the pasting of the insulating sheets can be guided in batches through multiple disassembly and assembly.

[0010] The connecting piece is arranged on at least one of the bracket and the baffle, for example, the connecting piece is arranged on the bracket, the connecting piece is arranged on the baffle, or the connecting piece is arranged on both the bracket and the baffle; the specific connection structure of the connecting piece and the battery module box depends on the specific structure of the battery module box, for example, if a threaded hole is provided on the battery module box, the connecting piece can be connected to the battery module box through a threaded connecting piece; if a positioning groove is provided on the battery module box, a positioning block of corresponding shape can be provided on the connecting piece to cooperate with it.

[0011] When pasting the insulating sheet, this solution is connected to the box of the battery module through the connector, and then the insulating sheet is pasted along the baffle; in this way, the pasting position and spacing of the insulating sheet match the position and spacing of the baffle. As long as the position and spacing of the baffle are configured in advance to match the designed pasting position and spacing of the insulating sheet, the pasting position and spacing of the insulating sheet can be ensured to be accurate; and the position and spacing of the baffle can be determined by machining. Therefore, compared with the existing technology of visually determining the pasting position of the insulating sheet, this solution can ensure that the position and spacing of the baffle match the designed position and spacing of the insulating sheet pasting area with higher accuracy, thereby ensuring that the position and accuracy of the insulating sheet meet the design requirements, avoiding inconsistent pasting effects, wrong positions, and crooked pasting of the insulating sheet.

[0012] As a preferred solution of the present invention, the distance between two adjacent baffles is adjustable.

[0013] The implementation of adjustable baffle spacing includes, but is not limited to, setting multiple installation positions for the baffles, movably connecting at least one baffle and a bracket, and movably connecting two adjacent baffles.

[0014] This solution makes the spacing of the baffles adjustable, thereby being able to adapt to the pasting operation of insulating sheets of battery modules of different models, thereby improving the versatility of this solution.

[0015] As a preferred solution of the present invention, at least one baffle is slidably connected to the bracket to adjust the distance between two adjacent baffles.

[0016] The baffle is slidably connected to the bracket, for example, a slide rail is provided on the baffle, and a slider is provided on the bracket; or a slider is provided on the baffle, and a slide rail is provided on the bracket.

[0017] This solution uses a sliding connection method to adjust the spacing of the baffles, which not only makes the spacing adjustment of the baffles more convenient, but also enables the baffle spacing to be adjusted steplessly, thereby adapting to more different insulation sheet spacings.

[0018] As a preferred solution of the present invention, a locking structure is further included, which can lock or unlock the position of the baffle on the bracket.

[0019] The locking structure includes but is not limited to a friction locking structure, a latch locking structure, and a snap-on locking structure.

[0020] This solution adds a locking structure to the baffle, which can lock the relative position between the baffle and the bracket, thereby keeping the distance between the baffles unchanged. On the one hand, it avoids the situation where the insulating sheet is pasted in the wrong position or crooked due to unexpected movement of the baffle when pasting the insulating sheet; on the other hand, it can also avoid the need to repeatedly adjust the baffle spacing when pasting equidistant insulating sheets, thereby improving work efficiency.

[0021] As a preferred solution of the present invention, a locking bolt is threadedly connected to one of the baffle and the bracket, and a first slide groove is provided on the other of the baffle and the bracket. The locking bolt is slidably connected to the first slide groove, and rotating the locking bolt can lock or unlock the position of the baffle in the bracket.

[0022] A locking bolt is threadedly connected to one of the baffle and the bracket, and a first slide groove is set on the other of the baffle and the bracket, for example, a locking bolt is set on the baffle and a first slide groove is set on the bracket; or a first slide groove is set on the baffle and a locking bolt is set on the bracket.

[0023] This solution provides one specific locking structure implementation method, which can not only lock and unlock the freedom of movement between the baffle and the bracket through the locking bolt, but also realize the sliding connection between the baffle and the bracket. It has multiple uses and has a high material utilization rate.

[0024] As a preferred solution of the present invention, connecting pieces are provided at both ends of the baffle along its length direction.

[0025] Since the baffle is used to guide the insulating sheet, its size is often longer and its rigidity is weaker. In this solution, the connecting parts are set at both ends of the baffle. When the connecting parts are connected to the battery module box, they can form a limit between the two ends of the baffle and the battery module box, thereby preventing the two ends of the baffle from deformation, warping, and other deviations from the designed position, thereby ensuring the position accuracy of the two ends of the baffle.

[0026] As a preferred solution of the present invention, the baffles are slidably connected to the connecting pieces to adjust the spacing between the connecting pieces on two adjacent baffles.

[0027] The baffle is slidably connected to the connecting member, for example, a slide rail is provided on the baffle, and a slider is provided on the connecting member; or a slider is provided on the baffle, and a slide rail is provided on the connecting member.

[0028] When the positioning holes on different models of battery module boxes are set at different horizontal positions, or the baffle is configured with adjustable spacing, the relative position of the connector and the insulating sheet pasting area may change, that is, the relative position of the connector and the baffle may change, thereby causing the spacing between the connectors on two adjacent baffles to change accordingly; this solution adapts to such changes through a sliding connection between the baffle and the connector, thereby ensuring the versatility of this solution.

[0029] As a preferred solution of the present invention, a second slider is provided on one of the baffle and the connecting member, and a second slide groove is provided on the other of the baffle and the connecting member, and the second slider is slidably connected to the second slide groove; the width of the second slider away from the end of the second slide groove is greater than the width of the second slider close to the end of the second slide groove.

[0030] A second slider is provided on one of the baffle and the connecting member, and a second slide groove is provided on the other of the baffle and the connecting member. For example, a second slider is provided on the baffle and a second slide groove is provided on the connecting member; or a second slide groove is provided on the baffle and a second slider is provided on the connecting member.

[0031] This solution recommends a specific implementation method of the sliding connection between the baffle and the connecting member, and stipulates that the width of the second slider is larger at one end and smaller at the other end, which can prevent the baffle and the connecting member from separating from each other and avoid falling parts.

[0032] As a preferred solution of the present invention, a limit pin is provided on the connector, and the limit pin is used to be inserted into a limit hole corresponding to the battery module box.

[0033] The specific forms of the limit pin include but are not limited to cylindrical pins, screws, columnar protrusions, etc. The limit pin and the connecting piece can be an integrated component, or two components that are permanently connected or detachably connected.

[0034] The limiting holes on the battery module box include but are not limited to threaded holes, through holes, and blind holes.

[0035] Since existing battery module boxes are all provided with limiting holes, this solution allows the connectors to directly utilize the existing limiting holes on the battery module box for connection, without the need to modify the battery module box, which can reduce the promotion cost of this solution.

[0036] As a preferred solution of the present invention, there are two baffles, which are respectively located at both ends of the bracket.

[0037] This solution only provides two baffles, which can reduce the manufacturing difficulty and manufacturing cost of this solution; and when the baffles are configured with adjustable spacing, this solution can reduce the workload of operators in adjusting the baffle spacing.

[0038] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0039] When the insulating sheet is pasted by the insulating sheet auxiliary device of the utility model, the pasting position and spacing of the insulating sheet match the position and spacing of the baffle, thereby ensuring that the position and accuracy of the insulating sheet meet the design requirements, avoiding the situation where the insulating sheet pasting effect is inconsistent, pasted in the wrong position, or pasted crookedly.
