Description

Technical Field

[0001] This application relates to the field of battery processing and technology, and in particular to an assembly fixture and battery pack assembly equipment. Background Technology

[0002] With the rapid development of the global new energy sector, liquid-cooled battery packs have become the mainstream solution for high-energy-density battery systems due to their efficient thermal management capabilities. In the assembly process of liquid-cooled battery pack modules, the application of insulating pads to the bottom of the modules is a crucial step. The core function of these insulating pads is to isolate the battery pack casing from the module, preventing direct contact and mitigating the risk of leakage and short circuits.

[0003] During the implementation of this application, the inventors discovered that the current method of pasting the bottom insulating pads of liquid-cooled battery packs mainly relies on manual pasting: workers visually align the insulating pads with the bottom edge of the battery pack, press them together manually, and paste them in multiple manual sessions. The manual or semi-manual adjustment method makes it difficult to ensure the parallelism and spacing consistency of multiple insulating pads, which can easily lead to pasting misalignment, resulting in poor contact between the insulating pads and the battery module, affecting insulation performance and subsequent assembly. Utility Model Content

[0004] The main technical problem solved by the embodiments of this application is to provide an assembly fixture that effectively solves the problem of positional deviation caused by improper operation in traditional manual pressing and bonding by setting a first guide rail, a slidable first positioning slider and a first locking mechanism.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application embodiment is: to provide an assembly fixture, including a base plate, a first slider and a first locking mechanism, wherein the base plate is provided with a first guide rail, the first positioning slider is slidably disposed on the first guide rail, the first positioning slider is provided with a first positioning structure for positioning the part to be positioned, and the first locking mechanism is disposed on the first positioning slider, the first locking mechanism being used to lock the first positioning slider at a preset position on the first guide rail.

[0006] Optionally, the first positioning structure includes a first clamping part and a second clamping part, the first clamping part and the second clamping part are disposed opposite to each other, and a clamping space for accommodating the part to be positioned is formed between the first clamping part and the second clamping part.

[0007] Optionally, there may be multiple first positioning structures, which are evenly arranged along the first slider.

[0008] Optionally, the first locking mechanism includes a first locking member, the first positioning structure has a first through hole, the first slider has a first mating part, the first locking member passes through the first through hole, and one end of the first locking member engages with the first mating part. The locking or releasing of the first positioning slider on the first slider is achieved by adjusting the tightness of the first locking member in the first through hole.

[0009] Optionally, the first locking mechanism includes a second locking member, the first slider is provided with a second through hole, the first guide rail is provided with a second mating part, the second locking member passes through the second through hole and mates with the second mating part, and the axial direction of the second locking member is perpendicular to the axial direction of the first locking member.

[0010] Optionally, the assembly fixture further includes a second positioning slider and a second locking mechanism. The base plate is also provided with a second guide rail. The first guide rail and the second guide rail are arranged opposite to each other. The second positioning slider is slidably arranged on the second guide rail. The second positioning slider is provided with a second positioning structure for positioning the part to be positioned. The second locking mechanism is arranged on the second positioning slider and is used to lock the second positioning slider at a preset position on the second guide rail.

[0011] Optionally, the second positioning structure includes a third clamping part and a fourth clamping part, which are disposed opposite to each other, and a clamping space for accommodating the part to be positioned is formed between the third clamping part and the fourth clamping part, wherein the second positioning structure and the first positioning structure are disposed opposite to each other.

[0012] Optionally, the base plate is further provided with a positioning mark, which is used to indicate the placement position of the part to be positioned on the base plate.

[0013] Optionally, there may be multiple second positioning structures, which are evenly arranged along the second slider.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in the embodiments of this application is to provide a battery pack assembly equipment, including any of the above-mentioned assembly fixtures.

[0015] This application provides an assembly fixture, including a base plate, a first slider, and a first locking mechanism. The base plate is provided with a first guide rail, and the first positioning slider is slidably disposed on the first guide rail. The first positioning slider is provided with a first positioning structure for positioning the part to be positioned. The first locking mechanism is disposed on the first positioning slider and is used to lock the first positioning slider at a preset position on the first guide rail. By setting the first guide rail on the base plate and slidably disposing the first positioning slider on the guide rail, flexible adjustment of the positioning spacing is achieved. When it is necessary to adapt to different models of liquid-cooled battery packs, the operator only needs to adjust the position of the first positioning slider on the guide rail to quickly change the bonding spacing of the insulating pad. This effectively solves the technical problems of fixed spacing and poor adaptability of traditional tooling. Furthermore, the setting of the first locking mechanism ensures that the first positioning slider can be firmly locked in the preset position, ensuring that the positioning structure remains stable during the bonding operation and will not be displaced due to external forces, thereby ensuring the repeatability and reliability of the bonding of the insulating pad.

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1 The assembly fixture 100 includes a base plate 1, a first positioning slider 2, and a first locking mechanism 3. The base plate 1 is made of aluminum alloy and has sufficient rigidity and strength. A first guide rail 11 is provided on the upper surface of the base plate 1. The first guide rail 11 has a T-slot structure and extends along the length of the base plate 1.

[0022] The first positioning slider 2 is slidably mounted on the first guide rail 11. The bottom of the first positioning slider 2 is provided with a T-shaped protrusion that cooperates with the first guide rail 11. The size of the T-shaped protrusion is precisely matched with the T-shaped groove of the first guide rail 11 to ensure smooth sliding without wobbling.

[0023] Please see Figure 2The first positioning slider 2 is provided with a first positioning structure 22 for positioning the part to be positioned. The first positioning structure 22 includes a first clamping part 221 and a second clamping part 222, which are disposed opposite to each other on both sides of the first positioning slider 2. A clamping space 223 for accommodating an insulating pad is formed between the first clamping part 221 and the second clamping part 222. Preferably, the inner surfaces of both the first clamping part 221 and the second clamping part 222 are provided with anti-slip textures to prevent the insulating pad from slipping during clamping. A positioning reference surface is provided at the bottom of the clamping space 223 to ensure that the insulating pad remains horizontal in the clamping state.

[0024] The first locking mechanism 3 is disposed on the first positioning slider 2 and is used to lock the first positioning slider 2 at a preset position on the first guide rail 11. The base plate 1 is also provided with a positioning mark 12, which is used to indicate the placement position of the component to be positioned on the base plate 1. In this embodiment of the application, the component to be positioned is an insulating pad.

[0025] The positioning mark 12 is coated with yellow paint and is in the shape of a long strip. The positioning mark 12 is aligned vertically with the clamping space of the first positioning structure 22. The operator can identify the correct placement position of the insulating pad through the positioning mark 12.

[0026] In use, first, according to the specifications of the liquid-cooled battery pack, loosen the first locking mechanism 3, slide the first positioning slider 2 to the appropriate position, and lock it. Then, place the insulating pad at the position indicated by the positioning mark 12, inserting one end of the insulating pad into the clamping space 223 of the first positioning structure 22. Next, align the bottom of the liquid-cooled battery pack with the insulating pad and press it down to complete the pasting. Finally, loosen the first locking mechanism 3 and remove the liquid-cooled battery pack with the insulating pad pasted. This embodiment, through the adjustable first positioning slider 2 and the first positioning structure 22, effectively improves the positioning accuracy of the insulating pad pasting, solving the problem of inaccurate positioning in traditional manual operation.

[0027] Please refer to section 2 for further information. Figure 3The first locking mechanism 3 includes a first locking member 33 and a second locking member 34, forming an XY bidirectional locking system. In this embodiment, the first locking member 33 and the second locking member 34 are bolts. Specifically, the first positioning structure 22 is provided with a first through hole 223, and the first locking member 33 passes through the first through hole 223. The first positioning slider 2 is provided with a first mating part (not shown), which is a threaded hole. The threaded end of the first locking member 33 engages with the first mating part 24. By adjusting the tightness of the first locking member 33 in the first through hole 223, the locking or releasing of the first positioning slider 2 in the Y-axis direction can be achieved. When the first locking member 33 is tightened, the bolt head presses against the first positioning structure 22, generating a downward clamping force, so that the first positioning slider 2 is tightly fitted with the first guide rail 11.

[0028] Furthermore, the first guide rail 11 is provided with a second through hole 25, and a second mating part (not shown) is also provided on the first guide rail 11. The first slider 2 is provided with a second through hole 25, and a second locking member 34 passes through the second through hole 25 and mates with the second mating part. The axial direction of the second locking member 34 is along the X-axis direction and is perpendicular to the axial direction (Y-axis direction) of the first locking member 33. The second locking member 34 is mainly used for positioning and locking in the X-axis direction to prevent the first positioning slider 2 from sliding along the first guide rail 11.

[0029] In this embodiment, the dual-locking system provides a more reliable locking effect. The first locking member 33 mainly bears the vertically downward locking force, ensuring a tight fit between the first positioning slider 2 and the first guide rail 11; the second locking member 34 mainly bears the horizontal locking force, preventing the first positioning slider 2 from axially moving on the guide rail. During adjustment, both locking members need to be loosened simultaneously. After moving the first positioning slider 2 to the target position, the second locking member 34 is tightened first for coarse positioning, and then the first locking member 33 is tightened for final locking. The vertical configuration of the dual locking members makes the locking force more evenly distributed, significantly improving the locking reliability.

[0030] Please continue reading. Figure 3 The base plate 1 is also provided with a second guide rail 13, which is arranged opposite to the first guide rail 11. The structure of the second guide rail 13 is the same as that of the first guide rail 11, both being T-slot structures, ensuring the standardization and interchangeability of the system. The first guide rail 11 and the second guide rail 13 are arranged in parallel, and the height of the two guide rails is consistent, ensuring that the positioning sliders installed on different guide rails are on the same horizontal plane.

[0031] Please continue reading. Figure 3The assembly fixture 100 further includes a second positioning slider 4 and a second locking mechanism 5. The second positioning slider 4 is slidably mounted on the second guide rail 13 and has a second positioning structure for positioning the part to be positioned. The second locking mechanism 5 is disposed on the second positioning slider 4 and is used to lock the second positioning slider 4 at a preset position on the second guide rail 13. The first positioning slider 2 and the second positioning slider 4 need to work in coordination to ensure that the insulating pad remains flat under double-sided clamping.

[0032] During adjustment, the distance between the two positioning sliders is first determined based on the length of the insulating pad. Then, both locking mechanisms are released simultaneously, moving the positioning sliders to their corresponding positions and locking them in place. The double-sided positioning design prevents the insulating pad from bending or deforming during application, ensuring adhesion quality. The second locking mechanism 5 and the first locking mechanism 3 can operate independently, allowing operators to adjust the positions of the two positioning sliders separately for insulating pads of different lengths, achieving greater flexibility in adaptation.

[0033] Furthermore, the second positioning structure includes a third clamping portion 421 and a fourth clamping portion 422, which are disposed opposite to each other, forming a clamping space between them for accommodating the insulating pad. The dimensions of the clamping space are consistent with those of the clamping space 223 of the first positioning structure 22.

[0034] The second positioning structure and the first positioning structure 22 are arranged opposite to each other, and the two positioning structures are symmetrically distributed at 180° on the base plate 1. When the insulating pad is placed on the base plate 1, both ends of the insulating pad are clamped by the first positioning structure 22 and the second positioning structure respectively, forming a double-end fixed positioning method.

[0035] In this embodiment, the dual-rail system operates with greater precision than the single-rail system. When placing the insulating pad, both ends are simultaneously inserted into the clamping space of the first positioning structure 22 and the second positioning structure 42, ensuring the flatness of the insulating pad. During the pressing of the liquid-cooled battery pack, the dual-sided positioning provides more uniform support, avoiding torsional stress that might occur with single-sided positioning.

[0036] In this embodiment, a dual-rail, dual-positioning slider configuration is adopted, combined with a dual-locking mechanism and a multi-positioning structure design. Multiple first positioning structures 22 are provided on the first positioning slider 2, and multiple second positioning structures are provided on the second positioning slider 4. The multiple first positioning structures 22 are evenly distributed along the first positioning slider 2, and the multiple second positioning structures are evenly distributed along the second positioning slider 4, with each side of the positioning structure corresponding to the other. This configuration allows for the simultaneous and precise positioning of multiple insulating pads at both ends in a single operation, improving production efficiency.

[0037] Furthermore, both the first locking mechanism 3 and the second locking mechanism 5 adopt a double-locking design, with each locking mechanism including a first locking element and a second locking element, forming an XY bidirectional locking system. The first locking mechanism 3 of the first positioning slider 2 includes a first locking element 33 passing through the first through hole 223, and a second locking element 34 passing through the second through hole 25 and engaging with the second mating part 113 on the first guide rail 11. The second locking mechanism 5 of the second positioning slider 4 adopts the same double-locking structure, ensuring that the locking reliability of the two positioning sliders is completely consistent. The vertical configuration of the double-locking system enables each positioning slider to have vibration and impact resistance capabilities, making it particularly suitable for the high-frequency operating environment of automated production lines.

[0038] This embodiment of the application embodies a high degree of automation and standardization. At the start of operation, the positions of two positioning sliders are simultaneously adjusted according to the specifications of the liquid-cooled battery pack, and the first positioning slider 2 and the second positioning slider 4 are locked respectively using a dual-locking system. Then, following the indication of positioning mark 12, multiple insulating pads are placed simultaneously, with both ends of each insulating pad inserted into the corresponding first positioning structure 22 and second positioning structure. During the pressing of the liquid-cooled battery pack, the multiple first positioning structures 22 and multiple second positioning structures 24 provide evenly distributed support force, and the multiple insulating pads simultaneously achieve a high-quality adhesion effect. After adhesion is completed, all locking mechanisms are simultaneously released, and the liquid-cooled battery pack with the insulating pads adhered is removed.

[0039] This application provides an assembly fixture 100, including a base plate 1, a first slider 2, and a first locking mechanism 3. The base plate 1 is provided with a first guide rail 11, and the first positioning slider 2 is slidably disposed on the first guide rail 11. The first positioning slider 2 is provided with a first positioning structure 22 for positioning the part to be positioned. The first locking mechanism 3 is disposed on the first positioning slider 2 and is used to lock the first positioning slider 2 at a preset position on the first guide rail 11. By setting the first guide rail 11 on the base plate 1 and slidably disposing the first positioning slider 2 on the first guide rail 11, flexible adjustment of the positioning spacing is achieved. When it is necessary to adapt to different models of liquid-cooled battery packs, the operator only needs to adjust the position of the first positioning slider 2 on the first guide rail 11 to quickly change the pasting spacing of the insulating pad. This effectively solves the technical problems of fixed spacing and poor adaptability of traditional tooling. Furthermore, the setting of the first locking mechanism 3 ensures that the first positioning slider 2 can be firmly locked in the preset position, ensuring that the positioning structure remains stable during the pasting operation and will not be displaced due to external forces, thereby ensuring the repeatability and reliability of the insulating pad pasting.
