[0024] Reference Figure 1-4 The embodiment of the utility model provides an assembly jig for assembling a support plate, which includes: an assembly base 1 and a plurality of magnets 2, wherein a product assembly groove 11 is opened on the assembly base 1, and the shape and size of the product assembly groove 11 match the shape and size of the support plate; the plurality of magnets 2 are evenly arranged at the bottom of the product assembly groove 11, and are used to adsorb the tinplate 34 and the magnets 2 on the support plate, and then fix the position of the support plate substrate 31, and the depth of the product assembly groove 11 is greater than or equal to the thickness of the assembled support plate.

[0025] The magnets 2 are evenly distributed at the bottom of the product assembly slot 11 to improve the uniformity of the adsorption force and ensure the adsorption and fixing effect. The depth of the product assembly slot 11 is greater than or equal to the thickness of the assembled support plate, which can ensure that the various components of the support plate can be guided and aligned through the product assembly slot 11 to ensure the alignment effect.

[0026] In this embodiment, the components of the support plate include a support plate substrate 31, two pieces of Mylar sheet 32, tinplate 34, and multiple magnetic bodies 33; wherein, the support plate substrate 31 is provided with a tinplate 34 mounting groove and a magnet 2 mounting groove, which are respectively used to install the tinplate 34 and the multiple magnetic bodies 33; the Mylar sheet 32 ​​is provided with an adhesive layer on one side, which is used to connect the Mylar sheet 32 ​​and the support plate substrate 31; wherein, the outer contours of the support plate substrate 31 and the Mylar sheet 32 ​​are matched with the product assembly groove 11.

[0027] The specific usage process of the assembly fixture is as follows: first place a piece of Mylar sheet 32 ​​into the product assembly groove 11, at this time, the adhesive layer of the Mylar sheet 32 ​​faces upward; then put in the support plate substrate 31, and under the limiting effect of the product assembly groove 11, the support plate substrate 31 can be aligned with the Mylar sheet 32, so that the support plate substrate 31 is bonded to the Mylar sheet 32; assemble the tinplate 34 and the magnetic body 33, and under the action of the magnet 2 at the bottom of the product assembly groove 11, assemble the tinplate 34 and the magnetic body 33 to press the support plate substrate 31 and the Mylar sheet 32; finally, the adhesive layer of the second piece of Mylar sheet 32 ​​faces downward and is bonded to the top of the support plate substrate 31 to complete the assembly.

[0028] Please refer to Figure 1 , Figure 2 In this embodiment, a product assembly groove 11 is opened on the assembly base 1 to place and fix the position of the support plate assembly, and then a plurality of magnets 2 are arranged at the bottom of the product assembly groove 11, which can be used to adsorb the magnetic body 33 or tinplate 34 on the support plate substrate 31, and then fix the position of the support plate assembly, so as to facilitate the subsequent assembly of the Mylar sheet 32; the assembly fixture of the utility model can facilitate the alignment between the various components of the support plate, and can fix the position of the components during the assembly process, thereby ensuring the stability of the support plate assembly and improving the yield rate of the support plate assembly.

[0029] For further information, please refer to Figure 1 , Figure 2The base is also provided with a first material removal avoidance groove 12 and a second material removal avoidance groove 13, which are symmetrically arranged on the two long sides of the product assembly groove 11 and are both connected to the product assembly groove 11. In this embodiment, the size and shape of the product assembly groove 11 correspond to the size and shape of the support plate. When the support plate is assembled, it is difficult for workers to take the assembled support plate out of the product assembly groove 11. Now, by adding the first material removal avoidance groove 12 and the second material removal avoidance groove 13, it is convenient for workers to take out the support plate, which greatly improves the efficiency of taking out the support plate, and then improves the efficiency of assembling the support plate.

[0030] Furthermore, the depths of the first material picking avoidance groove 12 and the second material picking avoidance groove 13 are the same, and are both 0.4-0.6 cm deeper than the depth of the product assembly groove 11. Due to the small thickness of the support plate, when the depths of the first material picking avoidance groove 12 and the second material picking avoidance groove 13 are the same as the depth of the product positioning groove 14, the contact surface between the worker's hand and the support plate is too small, and it is not easy to take out the assembled support plate. By deepening the depths of the first material picking avoidance groove 12 and the second material picking avoidance groove 13, this embodiment can facilitate the worker to partially extend his hand to the lower side of the support plate, thereby increasing the contact area between the hand and the support plate (the side surface and part of the bottom surface under the side surface), making it easier to take out the support plate.

[0031] Furthermore, the width of the first material taking avoidance groove 12 is 1-1.5 cm, the length is 4-6 cm, and the first material taking avoidance groove 12 and the second material taking avoidance groove 13 are of the same shape and size. Among them, limiting the width of the first material taking avoidance groove 12 to 1-1.5 cm can facilitate fingers to enter the first material taking avoidance groove 12, and limiting the length to 4-6 cm can facilitate multiple fingers to enter the first material taking avoidance groove 12, and the support plate can be supported by multiple fingers at the same time, thereby ensuring the efficiency of taking out the support plate.

[0032] For further information, please refer to Figure 1 , Figure 2 The base is also provided with two positioning grooves 14, which are respectively arranged on both sides of the first material taking avoidance groove 12, and the two positioning grooves 14 are both connected to the product assembly groove 11. The support plate base plate 31 is provided with ear protrusions corresponding to the position and shape of the positioning grooves 14. Through the cooperation between the ear protrusions and the positioning grooves 14, the support plate base plate 31 can be quickly positioned, which is convenient for installation.

[0033] In this embodiment, please refer to Figure 1 , Figure 2, the magnets 2 are provided with four, and the four magnets 2 are arranged in a rectangular array. In this embodiment, the product positioning groove 14 and the support plate are both square, and by distributing the four magnets 2 in a square array, the four magnets 2 can be evenly arranged in the product positioning groove 14, which can ensure the adsorption and fixing effect of the four magnets 2. In other embodiments, six, eight, etc. can be provided, and they can also be distributed in a circular array.

[0034] For further information, please refer to Figure 1 , Figure 2 The magnet 2 is a long strip magnet 2, and the length direction of the long strip magnet 2 is the same as the length direction of the product assembly slot 11. Setting the magnet 2 as a long strip magnet 2 can increase the contact area of ​​the magnet 2 and ensure the fixing effect.

[0035] For further information, please refer to Figure 1 , Figure 2 The assembly base 1 is provided with a plurality of magnet 2 slots 15, the magnet 2 slots 15 are arranged at the bottom of the product assembly slot 11, the magnet 2 is fixed in the magnet 2 slots 15 by glue, and the magnet 2 is flush with the bottom surface of the product assembly slot 11. In this embodiment, the magnet 2 is fixed by glue, and the fixing effect is good, and the magnet 2 is flush with the bottom surface of the product assembly slot 11, which can effectively prevent the magnet 2 from affecting the normal assembly of the support plate, and ensure the assembly effect.

[0036] Furthermore, the assembly jig also includes a pressing plate 4, a pressing protrusion 41 is provided in the middle of the pressing plate 4, the pressing protrusion 41 corresponds to the position of the product assembly groove 11, and the size of the pressing protrusion 41 is smaller than the product assembly groove 11. By adding a pressing plate 4 provided with a pressing protrusion 41, the components of the support plate can be compacted through the pressing protrusion 41 to ensure that the two Mylar sheets 32 are well bonded to the middle support plate substrate 31.

[0037] Furthermore, a slide groove 42 is provided in the middle of the pressing plate 4, and the pressing protrusion 41 can slide into or out of the slide groove 42, and the pressing protrusion 41 is connected to the bottom of the slide groove 42 via a compression spring 43. By adding a compression spring 43 between the pressing protrusion 41 and the pressing plate 4 and providing the slide groove 42 on the pressing plate 4, it is possible to effectively prevent the support plate from being damaged by excessive pressing force, thereby ensuring the assembly yield rate.

[0038] Furthermore, one end of the pressing plate 4 is hinged to the base, and when assembling the support plate, the pressing plate 4 is rotated to open the product assembly slot 11 for assembly. When compaction is required, the pressing plate 4 is rotated to perform compaction, which is convenient and quick.
