Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0027] EMBODIMENT

[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an adhesive jig suitable for steel sheets of different thicknesses comprises a fixed base 1, a lower heat insulation plate 2 connected to the fixed base 1, an upper heat insulation plate 3 connected to the lower heat insulation plate 2, a heating through hole 4 formed in the upper heat insulation plate 3, the heating through hole 4 being arranged corresponding to the bonding position of the steel sheet, a heating plate 5 connected to the upper heat insulation plate 3, a heating block 6 connected to the bottom of the heating plate 5, the heating block 6 being inserted into the heating through hole 4 and the bottom of the heating block 6 being arranged in contact with the steel sheet, a stop block 7 connected to the side edge of the upper heat insulation plate 3, an upper pressing plate 8 connected to the stop block 7, and the bottom of the upper pressing plate 8 being arranged in contact with the top of the heating plate 5.

[0029] In this invention, the fixed base 1, the lower heat insulation plate 2, and the upper heat insulation plate 3 are all provided with first positioning holes 9, and positioning screws 10 are connected to the first positioning holes 9. Simultaneously, the stop block 7 is provided with a second positioning hole, which is opposite to the first positioning hole, and the tip of the positioning screw extends into the second positioning hole. This structure improves installation accuracy and increases work efficiency.

[0030] The upper heat insulation plate 3 of this utility model has four heating through holes 4, which are located at the corners of the central area of ​​the upper heat insulation plate 3, which can improve processing efficiency.

[0031] In this invention, the upper pressure plate 8 has a first fixing hole 11, and a fixing bolt is connected to the first fixing hole 11. The top of the stop block 7 has a second fixing hole, which is opposite to the first fixing hole 11 and connected by a fixing bolt. This improves the stability of the pressing.

[0032] In this invention, the lower heat insulation plate 2 has a lower positioning groove for installing products; the upper heat insulation plate 3 has an upper positioning groove for installing products. This allows for accurate installation of different products, prevents misalignment, and improves work efficiency.

[0033] In this utility model, the heating plate 5 and the heating block 6 are integrally formed. The bottom of the heating block 6 protrudes from the heating through hole 4, which can ensure that the heating block can contact the product (steel sheet). Both the heating block and the heating plate are made of copper.

[0034] The working principle of this utility model is as follows:

[0035] In specific work, such as Figure 5 As shown, the parts of Product A and Product B that need to be bonded are connected with hot melt adhesive C, and then placed between the upper and lower heat insulation plates. At this time, the hot melt adhesive is at the heating through hole. Through the contact between the heating plate and the heating device, the heat is transferred to the heating block. The heating block activates the hot melt adhesive, so that the steel sheets are bonded.

[0036] At this point, the two types of steel sheets are bonded together using a hot-pressing process. The pull-out force between the two steel sheets is greater than 20N, which is greater than the pull-out force of conventional double-sided adhesive bonding, which is between 2-5N. This improves the strength of the bond.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of the present application, it should be noted that the terms "vertical", "horizontal", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship commonly used when the product of the application is used, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0039] In addition, the terms "horizontal", "vertical", and the like do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0040] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "set", "mount", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0041] The above is only the preferred embodiment of the present application, and is not used to limit the present application, and it should be noted that for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be considered as the protection range of the present application.
