DETAILED DESCRIPTION

[0014] This specific embodiment is a movable high-power formation machine conductive voltage plate assembly, and its structural schematic diagram is as follows Figure 1-Figure 9 As shown, the movable high-power forming machine conductive voltage plate assembly includes a first fixed seat 1, a second fixed seat 2, a pressing block assembly 3, a conductive assembly 4, an aluminum layer plate 5 and a heating plate 6. A first upper mounting groove and a first lower mounting groove are provided on a side of the first fixed seat 1 close to the second fixed seat 2, a second upper mounting groove is provided on the top of the second fixed seat 2, two ends of the pressing block assembly 3 are respectively installed in the first upper mounting groove and the second upper mounting groove, two ends of the conductive assembly 4 are respectively installed in the first lower mounting groove and the second lower mounting groove, and the aluminum layer plate 5 and the heating plate 6 are installed between the pressing block assembly 3 and the conductive assembly 4.

[0015] The pressing block assembly 3 includes a fiberboard 301, a mounting cavity is opened on the top of the fiberboard 301, and a silicone plate 302 is fixedly installed inside the mounting cavity. The silicone plate 302 can be a highly elastic silicone plate. At the same time, the silicone plate 302 can be fixedly installed in the mounting cavity opened in the fiberboard 301 by bonding with high-temperature double-sided tape.

[0016] A plurality of spring cavities are provided at the bottom of the fiberboard 301, and a wave spring 303 is fixedly connected to the interior of each spring cavity. A stainless steel guide plate 304 is fixedly installed at the bottom end of the wave spring 303. The wave spring 303 has the advantages of low stroke and high pressure. At the same time, the number and size parameters of the spring cavities and the wave spring 303 are determined according to the requirements of battery overcurrent, temperature rise, internal resistance, etc., and are matched with the conductive plate and calculated to obtain the required results.

[0017] A through groove is provided at the middle of both ends of the stainless steel guide plate 304, and two guide holes symmetrically arranged about the through groove are provided at both ends of the stainless steel guide plate 304, and a guide rod 305 is slidably provided inside each guide hole, and a limit block 306 is fixedly installed on the outer surface of the upper end of the guide rod 305, and a mounting hole is provided in the middle of the limit block 306, and a guide rod hole matching with the guide rod 305 is provided at the top of the first fixing seat 1 and the second fixing seat 2, and a spring groove connected with the guide rod hole is provided at the top of the first fixing seat 1 and the second fixing seat 2, and a first screw hole is provided on the first fixing seat 1 and the second fixing seat 2, and the limit block 306 is fixed by the cooperation of the first screw 308 with the first screw hole, and after the limit block 306 is fixed, a movable gap is left in the stainless steel guide plate 304 inside the first upper mounting groove and the second upper mounting groove; A spring 307 is sleeved on the outer portion of the lower end of the guide rod 305. The spring 307 is located inside the spring slot. One end of the spring 307 contacts the stainless steel guide plate 304. The other end of the spring 307 is fixedly installed inside the spring slot. Under the elastic force of the spring 307, the stainless steel guide plate 304 is always kept in an outwardly stretched state when not in operation (i.e., a gap is left between the stainless steel guide plate 304 and the first fixing seat 1 and the second fixing seat 2). During the installation process, one end of the stainless steel guide plate 304 is placed inside the first upper installation groove and the other end of the stainless steel guide plate 304 is placed inside the second upper installation groove, and both ends of the stainless steel guide plate 304 are in contact with the spring 307. At this time, there is a gap between one end of the stainless steel guide plate 304 and the first fixing seat 1 and between the other end of the stainless steel guide plate 304 and the second fixing seat 2 (such as Figure 4 shown); Then, after aligning the guide rod 305 on the limit block 306 with the guide hole provided in the stainless steel guide plate 304, the limit block 306 is passed through the notch provided at one end of the fiberboard 301 and pressed onto the upper surface of one end of the stainless steel guide plate 304; The process of the limit block 306 pressing on the stainless steel guide plate 304 is as follows: the limit block 306 drives the guide rod 305 to pass through the guide hole provided in the stainless steel guide plate 304 and enter into the guide rod hole provided in the first fixing seat 1, and the guide rod 305 is located inside the spring 307. At this time, the first screw 308 is first passed through the mounting hole provided in the middle of the limit block 306 and the first screw 308 is tightened in the first screw hole provided in the first fixing seat 1 to fix the limit block 306. The principle of installing the other end of the stainless steel guide plate 304 in the second installation groove is the same as above and will not be repeated here; Therefore, the present invention leaves a gap between the stainless steel guide plate 304 and the first fixing seat 1 and the second fixing seat 2 after installation. The setting of the gap reduces the friction force when the conductive voltage plate assembly moves, thereby effectively realizing the easy movement of the conductive voltage plate assembly. At the same time, the fiberboard 301 has the advantages of being hard enough and not deformed, and the segmented pressure blocks are more stable in applying local pressure without biasing the pressure, and are resistant to high temperatures.

[0018] The conductive component 4 includes an epoxy resin plate 401, both ends of the epoxy resin plate 401 are provided with mounting holes, the bottoms of the first fixing seat 1 and the second fixing seat 2 are provided with second screw holes, and the two ends of the epoxy resin plate 401 are respectively installed on the first lower mounting groove and the second fixing seat 2 opened in the first fixing seat 1 through the cooperation of the second screw 402 and the second screw hole; the side of the epoxy resin plate 401 away from the stainless steel guide plate 304 is fixed with a voltage copper sheet 403 and a current copper sheet 404 by a third screw; the side of the voltage copper sheet 403 and the current copper sheet 404 away from the epoxy resin plate 401 is precisely serrated, and the precision serration is formed by CNC precision carving, the voltage copper sheet 403 and the current copper sheet 404 constitute a conductive copper plate, and the serrated conductive copper plate makes the contact with the battery ear more complete, thereby effectively reducing the contact internal resistance, thereby effectively controlling the load power temperature rise.

[0019] The conductive voltage plate assembly is inserted into and installed on the aluminum layer plate 5 and the heating plate 6 of the chemical forming machine.

[0020] In summary, the pressure block assembly 3 in the conductive plate assembly of the present invention adopts a segmented structure, and the pressure source adopts a wave spring 303. Based on the advantages of the wave spring 303 with low stroke and high pressure, the thicker pole ear can more effectively receive a larger pressure within the width range, so that it can be more fully pressed and contacted with the conductive plate. At the same time, since there is a spring 307 between the pressure block assembly 3 and the first fixing seat 1 and the second fixing seat 2, a certain gap is left between the bottom of the pressure block assembly 3 and the surface of the heating plate 6 of the forming machine, so that the whole set of conductive plate assembly is easier to move. The serrated conductive copper plate effectively increases the pressure between the pole ear and the conductive copper plate under the same pressure conditions, thereby effectively reducing the contact internal resistance between the pole ear and the conductive copper plate. The present application avoids the problem of poor contact between the pole ear and the conductive copper plate due to insufficient pressure or uneven pressure applied to the pole ear by the integral pressing block for the thicker pole ear of a typical high-current battery, or due to the overly flat surface of the conductive copper plate. It also avoids the problem that other high-power conductive plate assemblies are difficult to move due to the large friction between the pressing block assembly and the heating plate of the formation machine.

[0021] All technical features in this embodiment can be freely combined according to actual needs.

[0022] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
