Description

Technical Field

[0001] This utility model relates to the field of heat insulation pad processing technology, specifically to a power battery heat insulation pad coating device. Background Technology

[0002] Power battery thermal insulation pads are an important component of the thermal management and thermal runaway protection system for new energy vehicle batteries. By coating the surface of the battery cell to build a thermal resistance barrier, they effectively inhibit heat conduction, delay the heat diffusion process, and improve the thermal stability and operational safety of the system.

[0003] However, existing thermal insulation pad wrapping mainly relies on manual operation, resulting in problems such as unstable precision, low efficiency, and poor consistency. The main issues are: manual material placement is prone to deviations of ±2mm, and roller pressure fluctuations exceed ±10%, leading to significant differences in edge bonding strength (typically around 3–8 N / cm); process connections rely on manual confirmation, with loading and transfer waiting time accounting for over 30%, and single-unit hourly output less than 10 pieces; low standardization of operations, with edge wrapping sequence and pressure relying on experience, resulting in a defect rate exceeding 15%. Furthermore, existing wrapping equipment is multifunctional and lacks integrated control of material conveying, precise positioning, and folding roller pressure; the platform design does not consider guiding the natural lifting of the edge, easily causing defects such as wrinkles and air pockets; the folding system has a lag in response, and trajectory deviation leads to edge omissions, affecting wrapping integrity; there is no compensation mechanism for fixture wear, resulting in uneven pressure distribution and potential structural damage or loose connections. In addition, facing multi-specification products and complex working conditions, existing wrapping equipment lacks multi-axis collaborative control, dynamic compensation, and environmental adaptive adjustment capabilities, making it difficult to guarantee packaging consistency and thermal insulation performance.

This equipment can adapt to the material characteristics and production requirements of power battery heat insulation pads, thereby improving the stability of heat insulation pad coating quality and production efficiency, and meeting the needs of large-scale and highly consistent heat insulation pad production.

[0005] The objective of this utility model is achieved through the following technical solution: A power battery heat insulation pad coating device includes a feeding module, a coating module, a conveying module, and a transfer module.

The second guide rail is located on the upper side of the first guide rail, and the first guide rail and the second guide rail are perpendicular to each other. There are two sets of short-axis roller mechanisms, which are symmetrically arranged at both ends of the second guide rail and are slidably connected to the second guide rail. The four corners of the carrying platform are connected to the fixed base plate through four support columns, and the carrying platform is located on the upper side of the second guide rail.

[0006] Based on further optimization of the above scheme, the feeding module includes a slide base plate, positioning columns and a feeding platform.

The two bottom ends of the n-shaped moving frame are respectively equipped with gripping blocks through a telescopic mechanism.

[0009] Based on further optimization of the above scheme, the distance between the two bottom ends of the n-shaped mobile frame is equal to the center distance between the loading platform and the bearing platform.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: A power battery heat insulation pad coating device includes a feeding module 10, a coating module 20, a conveying module 30, and a transfer module 40. The feeding module 10 and the conveying module 30 are respectively arranged on both sides of the coating module 20 (e.g., Figure 1 or Figure 6 As shown), the transfer module 40 is located on the rear side of the covering module 20 (i.e., Figure 1 (As shown on the upper side); Meanwhile, the feeding module 10, the covering module 20, the conveying module 30, and the transfer module 40 are all fixedly mounted on the operating table, such as... Figure 6 As shown.

[0023] like Figure 3 As shown: The covering module 20 includes a fixed base plate 21, a first guide rail 32, a long-shaft roller mechanism, a second guide rail 24, a short-shaft roller mechanism, and a supporting platform 26. The first guide rail 22 is fixedly mounted on the end face of the fixed base plate 21 (the bottom surface of the fixed base plate 21 is fixedly connected to the end face of the operating table, such as...). Figure 6As shown), the long-shaft roller mechanism consists of two sets symmetrically arranged at both ends of the first guide rail 22. The long-shaft roller mechanism is slidably connected to the first guide rail 22. Specifically, the long-shaft roller mechanism includes a first sliding base 231, a first 7-shaped bracket 232, and a long-shaft roller 233. The first sliding base 231 is slidably disposed on the end face of the first guide rail 22, and the first 7-shaped bracket 232 is disposed on the end face of the first sliding base 231. The two first 7-shaped brackets 232 are arranged opposite to each other, and the long-shaft roller 233 is rotatably disposed at the end of the first 7-shaped bracket 232 away from the first sliding base 231 (e.g., ...). Figure 3 (As shown). The second guide rail 24 is positioned above the first guide rail 22, and the first guide rail 22 and the second guide rail 24 are perpendicular to each other (as shown). Figure 3 As shown), the second guide rail 24 is connected to the end face of the fixed base plate 21 via the support frame 240. Two sets of short-axis roller mechanisms are symmetrically arranged at both ends of the second guide rail 24. The short-axis roller mechanisms are slidably connected to the second guide rail 24. Specifically, the short-axis roller mechanism includes a second sliding base 251, a second L-shaped bracket 252, and a short-axis roller 253. The second sliding base 251 is slidably arranged on the end face of the second guide rail 24, and the second L-shaped bracket 252 is arranged on the end face of the second sliding base 251. The two second L-shaped brackets 252 are arranged opposite each other, and the short-axis roller 253 is rotatably arranged at the end of the second L-shaped bracket 252 away from the second sliding base 251. Two long-axis rollers 233 and two short-axis rollers 253 are located on the same plane and are all located on the upper side of the bearing platform 26 (e.g., Figure 3 As shown; the long-axis roller 233 and the short-axis roller 253 have the same diameter, both φ20~30mm, and the outer surfaces of both the long-axis roller 233 and the short-axis roller 253 are covered with silicone; the difference is that the length of the long-axis roller 233 is greater than the length of the short-axis roller 253, the long-axis roller 233 corresponds to the length side of the heat insulation pad, and the short-axis roller 253 corresponds to the width side of the heat insulation pad). The four corners of the bearing platform 26 are connected to the fixed base plate 21 by four support columns 210, and the bearing platform 26 is set on the upper side of the second guide rail 24. The end face of the bearing platform 26 is detachably equipped with a positioning rectangular frame 260 (combined with...). Figure 1 and Figure 6 As shown, the positioning rectangle 260 is made of aluminum alloy and the size of the rectangular hole in the middle is 0.5 to 1 mm larger than the size of the heat insulation pad to be wrapped; the width of the positioning rectangle 260 is 1 to 2 mm and 45° chamfered guide edges are set around it.

[0024] like Figure 2 As shown: The feeding module 10 includes a slide base plate 11, positioning posts 12, and a feeding platform 13. The bottom surface of the feeding platform 13 is connected to the slide base plate 11 via four positioning posts 12. The bottom surface of the slide base plate 11 is set on the end face of the operating table (e.g., Figure 6As shown), the end face of the loading platform 13 and the end face of the bearing platform 26 are on the same plane; the loading platform 13 has a length of 100-500mm and a width of 50-300mm, thus accommodating heat insulation pads of different sizes. Figure 4 As shown: The conveying module 30 includes a fixed base 31, a support base 32, and a conveyor belt 33. The support base 32 is disposed on the end face of the fixed base 31, and the conveyor belt 33 (using a conventional conveyor belt structure) is disposed on the upper end of the support base 32. The fixed base 31 is disposed on the end face of the operating table, and the end face of the conveyor belt 33 is on the same plane as the end face of the loading platform 13 (e.g., ...). Figure 6 (As shown).

[0025] like Figure 5 As shown: The transfer module 40 includes a support frame 41, a sliding bracket 42, an n-shaped moving frame 43, and a gripping block 44. The support frame 41 is fixedly installed on the rear side of the covering module 20 (and is fixedly connected to the end face of the operating table), and the support frame 41 is a portal-shaped structure (e.g., Figure 5 As shown), the side of the support frame 41 crossbeam near the covering module 20 (as shown) Figure 1 (As shown on the lower side) A sliding bracket 42 is slidably installed, and an n-shaped movable frame 43 is installed at the end of the sliding bracket 42 away from the support frame 41 (e.g.) Figure 5 As shown), the two bottom ends of the n-shaped moving frame 43 are respectively equipped with gripping blocks 44 via telescopic mechanisms 440 (the telescopic mechanism 440 can be composed of existing conventional mechanical telescopic rods or hydraulic telescopic rods; a vacuum suction cup assembly can be installed on the gripping block 43, with an adjustable suction force of 0.3~0.5MPa. Under the initial conditions, that is, when the telescopic mechanism 440 drives the gripping block 44 to move downward, the gripping block 44 is located on the upper side of the roller of the long-shaft roller mechanism or the short-shaft roller mechanism). The distance between the two bottom ends of the n-shaped moving frame 43 is equal to the center distance between the loading platform 13 and the bearing platform 26; at the same time, the shortest distance between the bearing platform 26 and the opposite side of the conveyor belt 33 is not less than the shortest distance between the opposite side of the loading platform 13 and the bearing platform 26. The telescopic mechanisms 440 and the gripping blocks 44 at both ends of the n-shaped moving frame are synchronously controlled through the EtherCAT bus to realize the gripping block 44 on one side (i.e. Figure 6 The gripping block 44 on the right side (as shown) picks up the finished product, as well as the gripping block 44 on the other side (i.e. Figure 6 The grasping block 44 on the left side of the image shows the synchronous action of picking up the semi-finished product.

[0026] Operating procedure flow: First, the operator (using appropriate automated equipment) performs preliminary adhesive application (adhesive layer thickness controlled within the range of 0.15-0.3mm), adhesive scraping (using scraping pressure of 0.5-5N to stabilize the adhesive layer thickness within the target value ±0.02mm), cooling and curing (allowing the adhesive layer to cure rapidly within 15 seconds, with a peel strength stable greater than 10N / cm after curing), and encapsulation film application (the encapsulation film is located at the bottom with its adhesive side facing up, containing double-sided adhesive and release paper), to obtain a semi-finished heat insulation pad.

[0027] Next, the heat insulation pad semi-finished product is placed on the end face of the loading platform 13 (the material size can be matched and the positioning error ≤ ±0.5mm can be ensured by setting a limit block on the end face of the loading platform 13, completing the preparation gripping process, and the single cycle time is controlled within 5 seconds); then, the transfer module 40 is started (initially, the gripping block 44 on the left side of the transfer module 40 corresponds to the loading platform 13, and the gripping block 44 on the right side corresponds to the carrying platform 26), and the heat insulation pad semi-finished product on the end face of the loading platform 13 is gripped by the downward movement of the left gripping block 44 and the adsorption of the corresponding vacuum suction cup assembly (the negative pressure is 0.3~0.5MPa) (at the same time, if there is a finished product with a complete coating on the end face of the carrying platform 26, it is gripped by the downward movement of the right gripping block 44 and the adsorption of the corresponding vacuum suction cup assembly); then, the sliding bracket 42 moves the product onto the support frame 41. Figure 6 The device moves to the right, aligning the semi-finished heat insulation pad with the carrier platform 26 (at this time, if a finished heat insulation pad exists, it aligns with the conveyor belt 33). The semi-finished heat insulation pad is placed on the end face of the carrier platform 26 within the positioning rectangle 260 by the downward movement of the gripping block 44 and the release of negative pressure. (During placement, because the inner cavity of the positioning rectangle 260 is slightly larger than the heat insulation pad, and it has 45° chamfered guide edges with a width of 1-2mm around it, the edge of the encapsulation film naturally folds up along the chamfer during placement, forming a vertical edge structure with a height ≥5mm and a deviation ≤±0.5mm. Positioning pins and elastic ejector pins at the bottom of the carrier platform 26 can be used to achieve X / Y direction clamping and positioning, ensuring consistent adhesion.)

[0028] After the semi-finished heat insulation pad is positioned, the long-axis roller mechanism and the short-axis roller mechanism are activated to press its edges together: First, the short-axis roller 253 of the short-axis roller mechanism moves synchronously in opposite directions (i.e., towards each other) at a speed of 0.5–1 m / s, and rotates synchronously with the short-axis roller 253 to press the sealing film on the short side of the heat insulation pad. The pressing pressure is 5–10 N, and the pressing time for one side is ≤2 seconds. After that, the short-axis roller mechanism resets. Then, the long-axis roller 233 of the long-axis roller mechanism moves synchronously in opposite directions (i.e., towards each other) at a speed of 0.5–1 m / s, and rotates synchronously with the long-axis roller 233 to press the sealing film on the long side of the heat insulation pad in stages. The pressing pressure is 10–15 N, and the pressing time for one side is ≤3 seconds. All rollers (including long-axis roller 233 and short-axis roller 253) are equipped with built-in pressure sensors, and the cylinder pressure is controlled by PLC closed-loop regulation to ensure the uniformity and controllability of the pressing process; the bonding strength after edge binding is ≥5N / cm, and the dimensional deviation is ≤±0.5mm.

[0029] Finally, the pressed finished heat insulation pad is transferred to the conveyor belt 33 via the transfer module 40 to complete the conveying process.

The two sides of the protective shell are respectively provided with feeding window and discharging window corresponding to the feeding module 10 and the conveying module 30.
