Description

Technical Field

[0001] This invention relates to the technical field of battery assembly production equipment, specifically to an auxiliary tooling and method for pressing and curing after sealing and applying adhesive to an assembly box. Background Technology

[0002] The assembly box consists of a shell and a cover. To ensure a good overall seal, the shell and cover need to be sealed with adhesive. To improve production efficiency, multiple assembly boxes are first mounted on a dispensing carrier, and then sealed using an integrated adhesive sealing molding machine. As shown in patent 202511765112.0, this integrated adhesive sealing molding machine, after dispensing and pressure holding processes, can precisely dispense adhesive at 360° to the gaps between the pre-assembled shell and cover, preventing adhesive from seeping into the shell and ensuring a stable seal. As a load-bearing component, the overall height and sealing performance of the assembly box are crucial assembly standards.

[0003] However, existing equipment handles the instantaneous "pressing" action in just a few seconds, while adhesive curing often requires a considerable amount of time (ranging from minutes to tens of minutes, or even hours). Before the adhesive is fully cured, the removal of the dispensing carrier and the disassembly of the product can cause the assembly box to be subjected to vibration or external force during transport or handling, damaging the uncured adhesive layer structure and leading to a risk of seal failure. Simultaneously, many assembly box shells and covers inherently possess a certain degree of springback stress. Once the pressure head is withdrawn or pressure fluctuates, the workpiece's springback can cause uneven adhesive layer thickness and errors in overall height dimensions, resulting in dimensional deviations in the entire battery pack. This affects subsequent installation on the vehicle and may even create tiny gaps in certain areas, severely impacting seal reliability.

[0004] In view of the shortcomings of the prior art, the present invention aims to provide an auxiliary tooling that can quickly remove the adhesive from the dispensing carrier after dispensing and seal and then press and cure it again. Summary of the Invention

[0005] One of the purposes of this application is to provide an auxiliary tooling for pressing and curing after dispensing adhesive into an assembly box. This tooling can quickly disassemble multiple assembly boxes on the dispensing carrier and maintain continuous pressure during the adhesive curing process, thereby ensuring the sealing between the shell and the cover plate and the overall dimensional stability.

[0006] The second objective of this application is to provide a pressing method after applying adhesive to the sealing of an assembly box, which is simple to operate, has high disassembly efficiency, and provides a stable sealing effect for the assembly box.

[0007] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution: An auxiliary tooling for pressing and curing after dispensing adhesive into an assembly box includes a base, a plurality of fixing components and a pressing component disposed on the base. An L-shaped groove is formed on the base. The fixing components and the pressing components are respectively disposed on both sides of the L-shaped groove. The fixing components are used to clamp and position the housings on the dispensing carrier one by one. The pressing components are used to continuously press the cover plate on the top of the housing.

[0008] By utilizing a base with an L-shaped groove and a combination of multiple fixing and clamping components, "rapid demolding" and "secondary continuous pressure holding" of glued assembly boxes on the dispensing carrier are achieved. This solves the problems of air entry and cover rebound during glue curing of the assembly box, as well as the contradiction between the long glue curing cycle and the equipment's production capacity.

[0009] Preferably, the fixing component includes a U-shaped clamping block whose bottom is fixed to one side of the L-shaped groove.

[0010] By utilizing the elastic deformation capability of the U-shaped structure in the U-shaped clamp, the shell can be quickly snapped and positioned, greatly improving the efficiency of disassembling workpieces from the dispensing carrier.

[0011] Preferably, the front end of the U-shaped clamp is provided with a flared guide opening.

[0012] It significantly reduces the difficulty of alignment during assembly. Utilizing the guiding effect of the inclined plane, even with slight positional deviations, the housing can be smoothly guided into the U-shaped clamp, improving the convenience and speed of operation.

[0013] Preferably, the clamping assembly includes a pressure block and an elastic mechanism disposed between the pressure block and the L-shaped groove.

[0014] By utilizing the contraction and rebound force of the elastic mechanism, it automatically adapts to assembly boxes of different batches or slight size differences, ensuring that the cover plate is subjected to continuous and stable clamping force throughout the curing process, preventing gaps from forming in the adhesive layer.

[0015] Preferably, the front end of the pressure block is provided with an inclined guide edge.

[0016] The problem of hard collision when the pressure block contacts the cover plate has been solved. By using inclined sliding contact, the pressure block can smoothly cover the cover plate during the pressing process, avoiding the workpiece slipping or getting stuck.

[0017] Preferably, the U-shaped clamp or the base is provided with an adapter seat, and the rear end of the pressure block is connected to the adapter seat via a rotating shaft.

[0018] By restricting the movement of the pressure block to rotation around an axis, the direction of the clamping force is always perpendicular to the cover plate, avoiding displacement caused by lateral friction that may occur during linear sliding.

[0019] Preferably, the U-shaped clamp and the adapter are integrally bent from a metal plate.

[0020] It not only simplifies the processing flow and reduces welding or assembly steps, but also ensures the positional accuracy between the U-shaped clamp and the adapter, and facilitates overall replacement and maintenance.

[0021] Preferably, the transition end of the pressure block is provided with a stop block, and the position of the pressure block flipping outward through the elastic mechanism is controlled by the stop block.

[0022] The maximum tilt angle of the pressure block is controlled by a mechanical limit switch, thereby locking the pre-compression of the elastic mechanism. This ensures a highly consistent pressure value for each clamping operation, eliminating quality fluctuations caused by uneven manual operation.

[0023] Preferably, the elastic mechanism includes an adjusting screw fixed on the base, an adjusting nut on the adjusting screw, and a pressure-holding spring sleeved on the adjusting screw. The two ends of the pressure-holding spring are respectively limited by the adjusting nut and the pressure block, and the pressure-holding pressure of the pressure block is adjusted by the adjusting nut.

[0024] It achieves "stepless adjustment" of clamping force. The compression of the pressure holding spring can be changed by rotating the adjusting nut, thereby adapting to the specific pressure requirements of different assembly boxes or different glue processes.

[0025] Preferably, the base includes a bottom plate and a side plate connected in an L-shape, and the fixing component and the clamping component are fixed to the side plate and the bottom plate.

[0026] The second objective of this application is achieved through the following technical solution: A method for pressing after dispensing adhesive to seal an assembly box, comprising a pressing and curing auxiliary tooling, wherein the pressing method includes: S1. Flip the base so that the L-shaped groove faces the assembly box on the dispensing carrier, and ensure that the opening end of the fixing component is aligned with the corresponding assembly box, and press the component on the top of the cover plate. S2. Move the base to the assembly box direction to the end, so that the shell is snapped onto each U-shaped clamp. At the same time, make the pressure block retract upward after contacting the cover plate, so that the elastic mechanism is in an elastic contraction state. The pressure block forms a pressing force on the top of the cover plate through the contraction and rebound force of the elastic mechanism. S3. After the base is pressed into place, keep the tooling stationary. Place the assembled box shell with the glue applied upwards and stand upright. Keep it at a constant temperature for the preset time to allow the adhesive on the surface of the assembled box to flow and set naturally, preventing excess glue from flowing into the shell and causing internal cavity contamination, thus ensuring product performance. S4. After the adhesive for the assembly box has cured, remove the assembly boxes one by one from the clamping and curing auxiliary tooling.

[0027] By combining "demolding" and "curing and pressure holding" into one process, the entire row of assembly boxes can be transferred and pressurized through simple flipping and pushing actions, which greatly simplifies the production process and reduces labor intensity.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: By combining fixing and clamping components, assembly boxes that have been dispensed and pressurized on the dispensing carrier can be quickly disassembled in batches and subjected to secondary continuous pressure maintenance. This allows the dispensing carrier to be quickly unloaded and reused. Simultaneously, it avoids damage to the uncured adhesive layer structure caused by vibration or external forces during assembly box removal and disassembly, preventing air leakage, localized micro-gaps, and dimensional deviations after curing.

[0030] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0032] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character "=" generally indicates that the preceding and following objects have an "or" relationship.

[0033] Example 1: As Figures 1-3 As shown, an auxiliary tooling for pressing and curing after dispensing adhesive into an assembly box includes a base 4, a plurality of fixing components 1 and pressing components 5 disposed on the base 4. An L-shaped groove 8 is formed on the base 4. The fixing components 1 and pressing components 5 are respectively disposed on both sides of the L-shaped groove 8. The fixing components 1 are used to clamp and position the housing 21 on the dispensing carrier 30 one by one. The pressing components 5 are used to continuously press the cover plate 22 on the top of the housing 21.

[0034] After the assembly box 20 on the dispensing carrier 30 has completed the dispensing and pressure holding process using the ring-shaped dispensing and sealing integrated molding machine and has been removed, the operator can quickly disassemble the assembly box 20 on the dispensing carrier 30 using the fixing component 1 and the clamping component 5 on the clamping and curing auxiliary tooling, thus forming a secondary continuous pressure holding. This ensures that the assembled box 20, after initial pressure holding, is protected from air leakage, localized micro-gaps, and dimensional deviations in height after curing by the fixing component 1 and the clamping component 5. This effectively prevents the uncured adhesive layer structure from being damaged due to vibration or external force during the removal and disassembly of the assembly box 20. At the same time, it also allows the dispensing carrier 30 to be quickly put back into use. A further improvement is that the fixing component 1 includes a U-shaped clamping block 11 with its bottom fixed to one side of the L-shaped groove 8; the front end of the U-shaped clamping block 11 is provided with a flared guide port 6.

[0035] The fixing component 1 is composed of U-shaped clamps 11. The groove width of the U-shaped clamps 11 matches the external dimensions of the assembly box 20. When the assembly box 20 is inserted into the U-shaped clamps 11, it can be clamped and positioned by the U-shaped clamps 11. In particular, the outer side of the shell 21 of the assembly box 20 has raised ribs. After being fixed by the combination of the U-shaped clamps 11 and the ribs, the assembly box 20 can be prevented from moving when pressed. In order to ensure that multiple U-shaped clamps 11 can quickly connect with multiple assembly boxes 20, a flared guide port 6 is formed at the front end of the U-shaped clamps 11. The flared guide port 6 can quickly align the shell 21 of the assembly box 20 and put it into the U-shaped clamps 11, reducing the alignment time between the U-shaped clamps 11 and the shell 21.

[0036] A further improvement is made to the clamping assembly 5, which includes a pressure block 52 and an elastic mechanism 51 disposed between the pressure block 52 and the L-shaped groove 8.

[0037] The clamping assembly 5 consists of two parts: a clamping block 52 and an elastic mechanism 51. The clamping block 52 is used to clamp the top of the cover plate 22, while the elastic mechanism 51 acts as a pressure unit. In the non-working state, the clamping block 52 extends towards the fixing assembly 1 through the elastic force of the elastic mechanism 51. When the assembly box 20 is inserted into the U-shaped clamping block 11, the clamping block 52 moves synchronously towards the elastic mechanism 51 through the cover plate 22, thereby putting the elastic mechanism 51 under pressure. When the assembly box 20 is fully inserted into the U-shaped clamping block 11, the clamping block 52 is elastically pushed outward through the elastic mechanism 51 and forms a continuous holding pressure on the cover plate 22. This ensures that the housing 21 and the cover plate 22 can always maintain a tight fit during the glue curing process, preventing the uncured glue layer structure from being damaged due to vibration or external force during the removal and disassembly of the assembly box 20.

[0038] A further improvement is made to the elastic mechanism 51, which includes an adjusting screw 512 fixed on the base 4, an adjusting nut 511 on the adjusting screw 512, and a pressure-holding spring 513 sleeved on the adjusting screw 512. The two ends of the pressure-holding spring 513 are respectively limited by the adjusting nut 511 and the pressure block 52, and the pressure-holding pressure of the pressure block 52 is adjusted by the adjusting nut 511.

[0039] After adjusting the position of the adjusting nut 511 on the adjusting screw 512, the initial compression range of the pressure holding spring 513 can be controlled, thereby realizing the stepless adjustment of the clamping force of the pressure block 52, so as to adapt to the specific pressure requirements of different models of assembly boxes 20 or different glue processes.

[0040] A further improvement is that the front end of the pressure block 52 is provided with an inclined guide edge 7.

[0041] In order to ensure that the pressure block 52 can quickly guide and press against the cover plate 22 during the installation of the assembly box 20, an inclined guide edge 7 is formed at the front end of the pressure block 52. After being guided by the guide edge 7, the installation of the assembly box 20 can be made simpler and faster.

[0042] A further improvement to the above technical solution is that the U-shaped clamping block 11 or the base 4 is provided with an adapter 3, and the rear end of the pressing block 52 is connected to the adapter 3 through a rotating shaft; the adapter end of the pressing block 52 is provided with a stop block 2, and the position of the pressing block 52 flipped outward by the elastic mechanism 51 is controlled by the stop block 2.

[0043] When the pressure block 52 is positioned via the elastic mechanism 51, its elongated shape makes it prone to displacement, especially when entering the assembly / disassembly box 20, where pressure zone shifts are likely. Simultaneously, when pressed by the pressure-holding spring 513, the spring's inherent characteristics result in a large initial extension range but low pressure, making it difficult to achieve the desired pressing effect. Therefore, the rear end of the pressure block 52 is connected to the adapter 3 via a pivot. The adapter 3 provides a one-end limit, preventing lateral movement and ensuring the pressure block 52 is positioned in the top center of the cover plate 22 when pressed. In particular, a bent stop block 2 is formed at the transition end of the pressure block 52. When the pressure block 52 is flipped and popped out downward by the pressure holding spring 513, it can be stopped by the stop block 2 after flipping to a certain position. This controls the height of the pressure block 52 and also prevents the pressure holding spring 513 from completely releasing its elastic force. The pressure holding spring 513 is in a contracted state even when it is not holding pressure. After the early stretching elasticity of the pressure holding spring 513 is eliminated by the combination of the transition seat 3 and the stop block 2, the pressure block 52 can achieve the required pressure holding effect when it holds pressure on the assembly box 20 and completes the quick assembly process.

[0044] A further improvement is that the U-shaped clamp 11 and the adapter 3 are integrally bent from a metal plate, making their manufacturing simpler and more convenient, and reducing assembly difficulty. Especially during replacement, it allows for quick and complete replacement of all components except the elastic mechanism 51. Generally, the U-shaped clamp 11 and the adapter 3 are fixed to the base 4 by welding or screws.

[0045] A further improvement is that the base 4 includes a base plate 42 and a side plate 41 connected in an L-shape, and the fixing component 1 and the clamping component 5 are fixed to the side plate 41 and the base plate 42.

[0046] The base 4 consists of an L-shaped connecting base plate 42 and a side plate 41, which is lighter in weight and simpler in structure. It is especially convenient to pick up when inserting the assembly box 20 in batches. After assembly, it can be flipped 180° to be placed horizontally through the base plate 42 and the assembly box 20 is in an inverted state, which provides better stability during sealing and pressure holding.

[0047] A further improvement is that the contact surface of the pressure block 52 is provided with an insulating material, which is a polytetrafluoroethylene coating. When the pressure block 52 is made of a metal conductive material, it can prevent short circuits from occurring on the positive and negative electrodes of the assembly box 20 when they are pressed together.

[0048] Example 2: A method for pressing after dispensing adhesive to seal an assembly box, including a pressing and curing auxiliary tooling, the pressing method comprising: S1. Flip the base 4 so that the L-shaped groove 8 faces the assembly box 20 on the dispensing carrier 30, and ensure that the opening end of the fixing component 1 is aligned with the corresponding assembly box 20, and the pressing component 5 is located on the top of the cover plate 22. S2. Move the base 4 to the assembly box 20 and make the housing 21 snap onto each U-shaped clamp 11. At the same time, make the pressure block 52 contact the cover plate 22 and retract upward, so that the elastic mechanism 51 is in an elastic contraction state. The pressure block 52 forms a pressing force on the top of the cover plate 22 through the contraction rebound force of the elastic mechanism 51. S3. After the base 4 is pressed into place, keep the tooling stationary. Place the assembly box 20 with the shell 21 facing upwards and keep it at a constant temperature for a preset time to allow the adhesive on the surface of the assembly box 20 to flow and set naturally, preventing excess adhesive from flowing into the interior of the shell 21 and causing internal cavity contamination, thus ensuring the performance of the product. S4. After the adhesive for assembly box 20 has cured, disassemble assembly boxes 20 one by one from the pressing and curing auxiliary tooling.

[0049] During operation, simply align the clamping and curing auxiliary fixture with the dispensing carrier 30 and push it forward. The U-shaped clamp 11 and the clamping component 5 can clamp and press the shell 21 and the lid together. After releasing the fixing component 1 on the dispensing carrier 30, the clamping and curing auxiliary fixture can be removed, ensuring that all assembly boxes 20 are located on the clamping and curing auxiliary fixture. This allows the assembly boxes 20 to maintain long-term curing pressure. In particular, after removal, placing the assembly box 20 upright with the shell 21 facing upwards, in an inverted state, and allowing it to stand at a constant temperature for a preset time allows the adhesive on the surface of the assembly box 20 to naturally level and set. This prevents excess adhesive from flowing into the interior of the shell 21 and causing internal contamination, ensuring product performance. With the addition of this device, "demolding" and "curing pressure" are combined into one. The transfer and pressurization of the entire row of assembly boxes 20 can be completed with a simple flipping and pushing action, greatly simplifying the production process and reducing labor intensity.

[0050] Example 3: As Figure 4 As shown, based on embodiment 1 or 2, a further improvement is made in that the pressure block 52 is provided with a pressure sensor 40, and the base plate 42 is provided with a row of displays 50 corresponding to the pressure sensor 40. The pressure data of the pressure block 52 on the cover plate 22 is displayed through the displays 50.

[0051] Because the assembly box 20 requires sufficient pressure during the pressure holding process, insufficient pressure can easily lead to an ineffective fit between the housing 21 and the cover plate 22. Since the assembly box 20 needs to be filled with gas, leakage can easily occur after gas filling due to pressure issues. Therefore, based on Embodiment 1 or 2, a pressure sensor 40 and a display 50 are added. The pressure sensor 40 is installed on the back of the pressure block 52, with its top passing through the pressure block 52 and contacting the surface of the installed cover plate 22. Each pressure sensor 40 corresponds to a display 50, which is mounted on the base plate 42. After the assembly box 20 is installed, the current pressure value can be displayed on the display 50. When the pressure is insufficient, the pressure can be adjusted using the adjusting nut, thus ensuring sufficient pressure on the cover plate 22. The display 50 is neatly fixed on the base plate 42, creating a flat placement surface. By adding the pressure sensor 40 and the display 50, the problem of unstable cover sealing caused by insufficient pressure in the pressure block 52 not being detected in time is effectively solved.

[0052] Example 4: Figure 4As shown, a further improvement on any of the above embodiments is that the base 4 is also provided with an adjusting plate 70. The bottom of the housing 21 of the assembly box 20 to be pressurized is supported by the adjusting plate 70. When the housing 21 does not have a protruding or recessed structure that cooperates with the U-shaped clamping block 11, for example, when the outer surface of the assembly box 20 is smooth, the housing 21 cannot be positioned because its height direction cannot be limited. Therefore, by adding an adjusting plate to the base 4, the bottom of the housing 21 can be supported, so that the housing 21 can be positioned when there are no external protruding ribs. Among them, when the adjusting plate 70 is connected by a slide rail and slide groove or a bolt and adjusting hole, the relative position of the adjusting plate 70 can also be adjusted to adapt to support the bottom of the housing 21 of different heights.

[0053] Example 5: Figure 4 As shown, during the pressure holding process, if the assembly box 20 is removed for inflation before the pressure holding time is sufficient, the glue may not cure properly, causing the cover plate 22 to separate from the shell 21 after inflation. Therefore, based on any of the above embodiments, a further improvement is made. The improved device also includes a timer 60 to calculate the pressure holding time, preventing the operator from forgetting the pressure holding time and removing the assembly box 20 for inflation before the pressure holding time is sufficient, which could lead to the cover plate 22 separating from the shell 21 or causing air leakage. Generally, the timer 60 is a mechanical timer 60, which is fixed to the base 4 by magnetic attraction, adhesive, or threaded connection. During operation, after the assembly box 20 is fixed, only the pressure holding time needs to be set. Later, during disassembly, the timer 60 can be used to directly observe whether the pressure holding time has been met, thus effectively solving the problem of forgetting the pressure holding time when multiple batches of assembly boxes 20 are operated simultaneously.

[0054] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
