Description
Technical Field
[0001] This utility model relates to the field of metal strip coating technology, specifically to a coating mold with a straightening mechanism. Background Technology
[0002] High-voltage wiring harnesses for new energy vehicles have the following core characteristics: First, high voltage and high current: the operating voltage range is typically 300V to 1000V (DC), with some models reaching 1500V, requiring high-insulation materials; the rated current can reach over 300A, necessitating low-resistance design to reduce power loss. Second, sealing and environmental resistance: they must pass IP67 or higher waterproof rating tests to prevent moisture and dust intrusion, have a temperature resistance range of -40℃ to 150℃, and use flame-retardant materials. Third, electromagnetic compatibility: shielding layers reduce electromagnetic interference (EMI) and the impact of sensitive equipment (EMS), ensuring the stability of the entire vehicle system. Encasing conductive metal busbars in insulating material to address these core requirements presents a significant challenge, particularly ensuring the uniform wrapping of the metal busbars.
[0003] In existing technologies, the process of coating metal strips (such as aluminum strips) involves feeding, straightening, coating, and traction. The straightening direction adjustment of the metal strip is mostly achieved using a straightening machine, which relies on assembly precision and cannot guarantee the position of the metal strip after entering the mandrel. If the gap between the mandrel and the metal strip is reduced, the metal strip may get stuck, which could scratch the metal strip and affect product quality. Furthermore, the straightening machine and the mold cannot be seamlessly connected, and there is a risk of deformation of the metal strip during this distance. Summary of the Invention

[0022] like Figure 1-5 The illustrated overmolding mold with a straightening mechanism mainly includes a main frame 1, a straightening mechanism 2, and an overmolding mechanism 3. The straightening mechanism 2 and the overmolding mechanism 3 are described in detail below.
[0023] The straightening mechanism 2 is connected to the main frame 1. The straightening mechanism includes a straightening frame, a first straightening wheel group 21, and a second straightening wheel group 22. The straightening frame is connected to the main frame 1, and both the first straightening wheel group 21 and the second straightening wheel group 22 are connected to the straightening frame 2. The outlet of the first straightening wheel group 21 connects to the inlet of the second straightening wheel group 22, and the outlet of the second straightening wheel group 22 connects to the inlet 30 of the coating mechanism 3. Before entering the coating mechanism, the metal busbar (taking aluminum busbar as an example) undergoes secondary correction and position adjustment via the first straightening wheel group 21 and the second straightening wheel group 22. The straightening and coating of the aluminum busbar are seamlessly connected, avoiding the risk of deformation of the metal busbar.
[0024] In this embodiment: the straightening frame includes a first straightening frame 200 and a second straightening frame 201. A first straightening wheel assembly 21 is connected to the first straightening frame 200, and a second straightening wheel assembly 220 is connected to the second straightening frame 201. Wherein: The first straightening frame 200 includes a first upper straightening frame 200a and a first lower straightening frame 200b, which are parallel to each other. Similarly, the second straightening frame 201 includes a second upper straightening frame 201a and a second lower straightening frame 201b, which are parallel to each other. The first upper straightening frame 200a, the first lower straightening frame 200b, the second upper straightening frame 201a, and the second lower straightening frame 201b are connected to the main frame 1 as a whole, which facilitates the installation of the first straightening wheel set 21 and the second straightening wheel set 22.
[0025] like Figure 1 , 3 As shown in Figure 4, the first straightening wheel group 21 includes multiple first shaping wheels 210, which are distributed on the left and right sides. The aluminum strip passes between the first shaping wheels 210 on the left and right sides. Specifically, the first shaping wheels 210 are rotatably disposed between the first upper straightening frame 200a and the first lower straightening frame 200b, and the rotation axis of the first shaping wheels 210 is perpendicular to the first upper straightening frame 200a and the first lower straightening frame 200b.
[0026] Preferably, the multiple first shaping wheels 210 are staggered on the left and right sides.
[0027] The first straightening roller group 21 also includes a first adjustment unit, which is used to adjust the position of the first shaping roller 210 in the left and right direction. The first adjustment unit is connected to the first shaping roller 210, that is, each first shaping roller 210 is connected to a first adjustment unit for adjustment.
[0028] The following is a specific implementation of the first adjustment unit: The first adjustment unit includes a first rotating seat 211 and a first adjusting component 212. Specifically, the first rotating seat 211 is movably connected to the first upper straightening frame 200a and the first lower straightening frame 200b of the straightening machine frame in a left-right direction. The first upper straightening frame 200a and the first lower straightening frame 200b are provided with adjusting grooves 200c extending in the left-right direction. The first rotating seat 211 is disposed within the adjusting grooves 200c and can be moved and adjusted within them. The two ends of the first shaping wheel 210 are rotatably connected to the first rotating seat 211. Specifically, the upper end of the first shaping wheel 210 is connected to the first rotating seat 211 within the adjusting groove 200c of the first upper straightening frame 200a, and the lower end of the first shaping wheel 210 is connected to the first rotating seat 211 within the adjusting groove 200c of the first lower straightening frame 200b. The first adjusting member 212 is connected to the first rotating seat 211 and can move the first rotating seat 211. Specifically, the first adjusting member 212 passes through the first upper straightening frame 200a and the first lower straightening frame 200b and is connected to the first rotating seat 211. The first adjusting member 212 is threadedly connected to the first upper straightening frame 200a and the first lower straightening frame 200b. The first adjusting member 212 can be an adjusting screw or the like. Rotating the first adjusting member 212 causes it to move left and right relative to the first upper straightening frame 200a and the first lower straightening frame 200b through the thread, thereby pushing the first rotating seat 211 in the adjusting groove 200c to move, and finally driving the first shaping wheel 210 to move and adjust.
[0029] like Figure 1 , 3 As shown in Figure 5: The second straightening wheel assembly 22 includes at least one pair of second shaping wheels 220, which are distributed vertically. The aluminum strip passes between the pair of second shaping wheels 220 in the vertical direction. Specifically: the upper shaping wheel of the pair of second shaping wheels 220 is rotatably connected to the second upper straightening frame 201a, and the lower shaping wheel of the pair of second shaping wheels 220 is rotatably connected to the second lower straightening frame 201b. The rotation axis of the second shaping wheel 220 is parallel to the second upper straightening frame 201a and the second lower straightening frame 201b.
[0030] The second straightening roller assembly 22 also includes a second adjustment unit, which is used to adjust the position of the second shaping roller 220 in the vertical direction. The second adjustment unit is connected to the second shaping roller 220, that is, each second shaping roller 220 is connected to a corresponding second adjustment unit for adjustment.
[0031] The following is a specific implementation of the second adjustment unit: The second adjustment unit includes a second rotating seat 221 and a second adjusting member 222. Specifically, the second rotating seat 221 is movably connected to the second upper straightening frame 201a and the second lower straightening frame 201b of the straightening machine frame. The second shaping wheel 220 is rotatably connected to the second rotating seat 221; that is, one second rotating seat 221 is connected to one second shaping wheel 220. One end of the second adjusting member 222 is threadedly connected to the second rotating seat 221. Specifically, the second adjusting member 222 is a lead screw; its lower end is threadedly connected to the second rotating seat 221, and its upper end is connected to a handwheel 223. Since the second rotating seat 221 is restricted to movement by the second upper straightening frame 201a and the second lower straightening frame 201b, rotating the second adjusting member 222 causes the second rotating seat 221 to move up and down, ultimately causing the second shaping wheel 220 to move and adjust.
[0032] If the second shaping wheel 222 is only connected to the second adjusting member 222, all its force is borne by the lead screw, resulting in force concentration and easy damage to the lead screw. Therefore, the second adjusting unit also includes a guide column 224 and a locking member 225. The guide column 224 is connected to the second upper straightening frame 201a and the second lower straightening frame 201b of the straightening machine frame and extends in the vertical direction. As shown in the figure, guide columns 224 are respectively provided on both sides of the second adjusting member 222. The second rotating seat 221 cooperates with the guide column 224 through the connecting frame 226. The guide column 224 serves two purposes: firstly, it provides guidance; secondly, after adjustment, it transfers the force borne by the second adjusting member 22 to itself, improving stability. The locking element 225 is connected to the second rotating seat 221 or the connecting frame 226 and can be fixed relative to the guide post 224 when locked. Specifically, the locking element 225 is a clamp. When adjustment is required, the clamp is loosened so that the second rotating seat 221 can move. After the adjustment is completed, the clamp is tightened so that the second rotating seat 221 is fixed to the guide post 224 through the locking element 225.
[0033] The coating mechanism 3 is connected to the main frame 1. The coating mechanism 3 has a feed inlet 30 and an injection port 31. The feed inlet 30 is connected to the second straightening wheel group 22, which means that the aluminum strip randomly enters the feed inlet 30 after the second straightening wheel group 22. The adhesive enters the interior of the coating mechanism 30 from the injection port 31 and completes the coating of the aluminum strip through the core mold and the die inside the coating mechanism 3.
[0034] This invention equips the overmolding mold with a front straightening mechanism, which is especially suitable for overmolding products such as aluminum strips that are soft and easily deformable. It performs correction and position adjustment before overmolding to ensure that the product dimensions are qualified and the uniformity of overmolding is within 0.1mm.
[0035] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
