[0001] The utility model relates to the field of jigs, and in particular to a novel positioning graphite sheet attaching jig. Background Art

[0002] With the rapid development of electronic products, the requirements for the attachment process of internal components are becoming higher and higher. However, the traditional graphite sheet attachment method relies on manual positioning and attachment, which often has problems such as inaccurate positioning and low attachment efficiency that need to be overcome and solved.

[0003] During the graphite sheet attachment process, due to the lack of clear attachment position markings in the workstation structure, operators often encounter positioning difficulties when attaching graphite sheets. This situation leads to frequent undesirable phenomena such as graphite sheet attachment deviation and wall climbing. In order to solve this problem, operators often need to tear off the deviated graphite sheets and re-attach them, which not only reduces production efficiency, but also easily leads to product accumulation in the workstation, and is more likely to cause the performance of the graphite sheets to not be fully utilized, affecting the final quality and performance of the product.

The jig 1 includes a jig base 12 and an air suction base 16, wherein the air suction base 16 is disposed on the jig base 12, and a preset number of air suction holes 160 are disposed on the air suction base 16, wherein the air suction holes 160 pass through the air suction base 16, and the air suction holes 160 are used to connect to the air suction device, so that air is generated in the air suction holes 160, and the graphite sheet 2 is placed on the air suction base 16, and the air suction holes 160 adsorb the graphite sheet 2, thereby completing the accurate positioning of the graphite sheet 2. The suction device described here refers to a vacuum negative pressure pump, or other equipment that can generate negative pressure or suction. The devices and equipment in this regard belong to the prior art, and the specific structure of the suction device is not within the scope of the specific description of this application. The suction device is connected to the suction hole 160 through a vent pipe, and negative pressure is generated in the suction hole 160, thereby accurately adsorbing the graphite sheet 2. Of course, the strength of the graphite sheet 2 being adsorbed can be determined by the attraction or negative pressure generated by the suction device, so that the adsorption force can be controlled.

[0029] In one embodiment of the present application, the jig further includes a graphite sheet limiting structure 17, the graphite sheet limiting structure 17 is disposed on the jig base 12, the graphite sheet limiting structure encloses a graphite sheet limiting space, the suction base 16 is located in the graphite sheet limiting space, so that the graphite sheet limiting space limits the graphite sheet, and the suction base 16 accurately positions the graphite sheet.

Here, the suction base 16 is formed on the product positioning groove 122, which means that the suction base 16 is provided on the product positioning groove 122, or the suction base 16 is a part of the product positioning groove 122.

[0031] In one embodiment of the present application, the jig further includes a preset number of product positioning posts 15, the product positioning grooves 122 are recessed on the jig base 12, thereby forming a jig edge 123 on the jig base 12, and the product positioning posts 15 are detachably fixed on the jig edge 123, and the positioning posts 15 are used to position the product to which the graphite sheet is to be attached on the jig base 12.

In this way, the jig base bottom plate 11 moves up and down with the springs 13, and the springs 13 provide a buffering force for the jig base 12. After the graphite sheet 2 is adsorbed on the jig base 12, the product to be bonded with the graphite sheet is pressed down onto the jig base 12. Since the product has an impact force during the pressing process, the springs 13 buffer this part of the impact force to a large extent, so that the product will not easily crush the graphite sheet.

[0035] In one embodiment of the present application, the jig base 12 is provided with first mounting through holes 120 having the same number as the springs 13, and the first mounting through holes 120 pass through the edge 123 of the jig base 12; the jig base bottom plate 11 is provided with second mounting through holes (not shown in the figure) corresponding to the first mounting through holes 120, and the second mounting through holes pass through the jig base bottom plate 11; one end of the spring 13 is fixedly installed in the first mounting through hole 120 by an interference fit connection, and the other end of the spring 13 is fixedly installed in the second mounting through hole by an interference fit connection.
