Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel belt coating equipment, in particular to a steel belt coating machine. BACKGROUND

[0002] Battery bundling steel belt mainly plays a core role in structural fixation and safety protection in the battery module; the steel belt tightly binds the battery cell in the specified position by surrounding the battery module and applying uniform pressure, preventing displacement and collision caused by the expansion and contraction of the battery cell during the charging and discharging process or external vibration and impact. This fixing function ensures the stability of the module shape, which is beneficial to the accurate monitoring of the battery management system and the efficient heat dissipation of the thermal management system. The steel belt has excellent mechanical support and fatigue resistance, can resist the huge expansion force generated by the battery cell, avoid module deformation or collapse, and its fatigue resistance can withstand the periodic stress caused by the charging and discharging cycle for a long time, maintaining a stable tightening force. In order to prevent the risk of insulation failure or short circuit caused by the contact between the aluminum shell of the battery cell and the steel belt during thermal runaway, the surface of the steel belt needs to be coated with a layer of adhesive tape. Steel belt coating can enhance the corrosion resistance, insulation and slip resistance of the steel belt, while reducing the risk of electrochemical reaction when the steel belt contacts the battery, and improving the overall safety. The existing steel belt coating process is mostly manual operation, workers wind the adhesive tape on the steel belt one by one, and the adjacent two layers of adhesive tape overlap to avoid the exposure of the steel belt. This steel belt coating method is time-consuming and labor-intensive, and wastes adhesive tape, resulting in high production cost. Some workers paste the adhesive tape on one side of the steel belt, then fold and paste the upper and lower ends of the adhesive tape to the other side of the steel belt. However, the steel belt is relatively long, and this steel belt coating method is prone to uneven adhesive tape or exposed steel belt when manually pasting the adhesive tape, resulting in low efficiency and poor quality stability of the processed products, and prone to defective products.

Therefore, they should not be construed as limitations on this invention. At the same time, the terms "first," "second," etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this invention.

[0036] like Figures 1-14As shown, this invention discloses a steel strip coating machine: including a worktable 1, a coating track 2 set on the worktable 1, and a strip feeding mechanism 3, a strip bending mechanism 4, a strip pressing mechanism 5, and a strip pressing mechanism 6 arranged sequentially along the coating track 2; the coating track 2 is provided with a steel strip driving assembly 21, which is used to drive the steel strip to be transported along the coating track 2 and pass sequentially through the strip feeding mechanism 3, the strip bending mechanism 4, the strip pressing mechanism 5, and the strip pressing mechanism 6. The strip feeding mechanism 3 is used to attach the strip to one side wall of the steel strip, the strip bending mechanism 4 is used to bend the upper and lower ends of the strip towards the other side wall of the steel strip, the strip pressing mechanism 5 is used to fold the lower end of the strip upward and attach it to the lower end of the other side wall of the steel strip, and the strip pressing mechanism 6 is used to fold the upper end of the strip downward and attach it to the upper end of the other side wall of the steel strip.

[0037] like Figure 1 and Figure 2 As shown, the cross-section of the rubber-coated track 2 is arranged in a vertical groove shape, which can make the steel strip vertical during transmission. The rubber-coated track 2 is divided into a front track and a rear track, which are respectively set at both ends of the workbench 1, and the distance between them is less than the length of a single steel strip. The front track and the rear track are suspended, which can avoid affecting the rubber coating process.

[0038] There are two steel belt drive assemblies 21, which are respectively set at both ends of the rubber-coated track 2. The distance between the two steel belt drive assemblies 21 is less than the length of a single steel belt, so as to ensure stable transmission of the steel belt.

[0039] like Figure 3 As shown, the steel belt drive assembly 21 includes a first bracket 211, a first drive wheel 212, a first pressing wheel 213, a first drive unit 214, and a first pressing unit 215. The first bracket 211 is connected to the workbench 1. The first drive unit 214 and the first pressing unit 215 are fixedly mounted on the first bracket 211. The first drive wheel 212 and the first pressing wheel 213 are respectively connected to the output ends of the first drive unit 214 and the first pressing unit 215. The first drive wheel 212 and the first pressing wheel 213 are respectively located on both sides of the rubber-coated track 2. The first drive unit 214 is used to drive the first drive wheel 212 to rotate circumferentially. The first pressing unit 215 is used to apply a force to the first pressing wheel 213 in the direction of the first drive wheel 212, so that the first pressing wheel 213 and the first drive wheel 212 are pressed against the two side walls of the steel belt on the rubber-coated track 2.

[0040] The first drive unit 214 can be a motor, and the first clamping unit 215 is a cylinder. The output end of the cylinder is connected to a spring pressure head to prevent the cylinder output pressure from being too high and damaging the steel belt. The first drive wheel 212 is also provided with a limiting groove on its wheel surface. The width of the limiting groove is the same as the height of the steel belt, so that the steel belt can be conveyed horizontally.

[0041] like Figure 4 As shown, the tape feeding mechanism 3 includes a tape support base 31, a tape rotating seat 32, a second pressing unit 33, and a tape pressing wheel assembly 34. The tape support base 31 is connected to the workbench 1, and the tape rotating seat 32 is rotatably connected to the workbench for placing the tape roll. The second pressing unit 33 is fixedly mounted on the tape support base 31. The tape pressing wheel assembly 34 includes two second pressing wheels 341, which are respectively located on both sides of the tape-coating track 2. The second pressing wheel 341 on the side closer to the tape rotating seat 32 is rotatably connected to the output end of the second pressing unit 33, and the other second pressing wheel 341 is rotatably connected to the tape support base 31. The second pressing unit 33 is used to drive the corresponding second pressing wheel 341 to move closer to the other second pressing wheel 341, thereby pressing the tape against one side wall of the steel belt.

[0042] Below the supporting base 31, a shearing assembly 35 is also provided, which is used to cut the tape. Specifically, the shearing assembly 35 includes a shearing drive unit, and a shearing module is provided on the output end of the shearing drive unit. The shearing drive unit can drive the shearing module (automatic shearing blade) to move vertically up and down. After the shearing module passes the end of a single steel strip, it cuts the tape, facilitating the tape coating operation of the next steel strip. In addition, in order to ensure that the tape is stably adhered to the steel strip, a tape guide wheel assembly 36 is also provided in front of the shearing assembly 35 (near the end of the steel strip feeding). The tape guide wheel assembly 36 guides the tape and adheres it to the steel strip. Before the shearing assembly 35 cuts, the front end of the next steel strip has already been coated with tape, thus ensuring the continuity of equipment operation. Both the second pressing unit 33 and the shearing drive unit are driven by cylinders.

[0043] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the tape bending mechanism 4 includes a tape bending assembly 41 and a tape flattening assembly 42. The tape bending assembly 41 is used to bend the upper and lower ends of the tape toward the other side of the steel belt, and the tape flattening assembly 42 is used to press the upper and lower ends of the bent tape to make the tape and the upper and lower ends of the steel belt fit tightly together.

[0044] like Figure 5As shown, the tape bending assembly 41 includes a side baffle 411 connected to the workbench 1. The side baffle 411 is located on the side of the tape feeding mechanism 3 near the tape feeding mechanism 2. The side baffle 411 is provided with two pressure plates 412. The two pressure plates are symmetrically arranged on the upper and lower sides of the tape feeding mechanism 2, and the distance between the two pressure plates 412 gradually decreases along the transmission direction of the steel belt (the minimum distance between the two pressure plates 412 is not less than the width of the steel belt). In this way, when the tape passes through, it will be squeezed by the two pressure plates 412. Due to the restriction of the side baffle 411, the upper and lower ends of the tape can only be bent into a horizontal state towards the other side of the steel belt.

[0045] like Figure 6 As shown, the tape pressing assembly 42 includes a second bracket 421 connected to the workbench 1. Two third pressing wheels 422 are rotatably connected to the second bracket 421. The two third pressing wheels 422 are symmetrically arranged on the upper and lower sides of the tape-coating track 2, and the distance between the two third pressing wheels 422 is the same as the height of the steel strip, which is used to press the tape firmly at the upper and lower ends of the steel strip.

The tape lower groove pressing assembly 51 is used to fold the bent portion at the lower end of the tape upward for the first time, the tape lower counter-pressing assembly 52 is used to push the bent portion at the lower end of the tape upward, the tape lower folding assembly 53 is used to fold the bent portion at the lower end of the tape upward for the second time, and the tape lower pressing assembly 54 is used to press the bent portion at the lower end of the tape onto the steel belt.

[0047] like Figure 7 As shown, the tape lower groove pressing assembly 51 includes a third bracket 511 connected to the workbench 1 and a first roller 512 and a first grooved wheel 513 rotatably connected to the third bracket 511. The first grooved wheel 513 has a concave groove on its wheel surface. The first roller 512 and the first grooved wheel 513 are symmetrically arranged at the upper and lower ends of the tape-coating track 2. When the tape passes through the tape lower groove pressing assembly 51, the groove shape of the first grooved wheel 513 will fold the lower end of the tape upward from the horizontal state, completing the initial bending operation.

[0048] like Figure 8As shown, the tape pressing assembly 52 includes a first support base plate 521 connected to the workbench 1, a first vertical drive unit 522 connected to the first support base plate 521, and a first flattening roller assembly 523 rotatably connected to the output end of the first vertical drive unit 522. Two flattening rollers on the first flattening roller assembly 523 are symmetrically arranged on both sides of the steel belt. The first vertical drive unit 522 is used to drive the first flattening roller assembly 523 to move up and down. The first flattening roller assembly 523 presses the lower end of the steel belt to stick the tape onto the steel belt.

[0049] like Figure 9 As shown, the tape folding assembly 53 includes a fourth bracket 531 connected to the workbench 1 and a first folding roller 532 rotatably connected to the top of the fourth bracket 531. The first folding roller 532 is inclined from bottom to top toward the side away from the steel belt. When the steel belt passes by, the tape portion at its lower end that has not yet been pasted is folded twice under the push of the first folding roller 532.

[0050] like Figure 10 As shown, the tape lower pressing assembly 54 includes a fifth bracket 541 connected to the workbench 1, a first pressing drive unit 542 and a lower pressing wheel assembly 543 disposed on the fifth bracket 541. The lower pressing wheel assembly 543 includes two fourth pressing wheels, which are symmetrically disposed on both sides of the tape-coating track 2. One of the fourth pressing wheels is rotatably connected to the fifth bracket 541, and the other is rotatably connected to the output end of the first pressing drive unit 542. When the tape after being folded twice passes through the lower pressing wheel assembly 543, it will be squeezed by the two fourth pressing wheels, and finally the tape lower end pasting operation is completed.

One of the fifth pressing wheels is rotatably connected to the eighth bracket 641, and the other is rotatably connected to the output end of the second pressing drive unit 642.

[0056] The first vertical drive unit 522, the first pressing drive unit 542, the second vertical drive unit 622, and the second pressing drive unit 642 mentioned above are all cylinders. The tape pressing assembly 62, the tape folding assembly 63, and the tape pressing assembly 64 are all based on the same principle as the tape lower pressing assembly 52, the tape lower folding assembly 53, and the tape lower pressing assembly 54, and will not be described in detail here.

[0057] This invention features a rubber-coated track 2 for conveying steel belts on a workbench 1. During the conveying process, the steel belt is adhered to one side wall of the steel belt by a belt feeding mechanism 3. Then, the upper and lower ends of the belt are bent towards the other side wall of the steel belt by a belt bending mechanism 4. Finally, the upper and lower ends of the belt are folded over by a belt pressing mechanism 5 and a belt pressing mechanism 6 and bonded to the upper end of the other side wall of the steel belt. The entire steel belt rubber coating process is fully automated and requires no manual operation. This not only ensures high efficiency but also provides stable steel belt rubber coating quality and a high yield rate.
