[0031] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments, and only the parts related to the embodiments of the present utility model are shown.

[0032] Embodiment 1:

[0033] As Figure 1As shown in the figure, the utility model provides a glue - sticking jig, which includes a base 1 and a squeegee 2. The base 1 is provided with positioning posts 11 and a receiving groove 12 for placing a radiator 3 to be glued. The receiving groove 12 matches the radiator 3. The positioning posts 11 are fixed at one end of the base 1, and the positioning posts 11 correspond one - to - one with the positioning holes 51 on the double - sided tape. The positioning posts 11 are used to install and position the double - sided tape. When gluing, the radiator 3 to be glued is placed in the receiving groove 12 of the base 1, the double - sided tape is installed and positioned on the positioning posts 11, and the bottom surface of the double - sided tape is adhered to the corresponding radiator 3 through the squeegee 2. Specifically, the receiving groove 12 is arranged on the upper part of the base 1, and the size of the receiving groove 12 matches the size of the radiator 3, ensuring that the radiator 3 can be stably placed in the receiving groove 12, and during the gluing process, the radiator 3 will not shake in the receiving groove 12, ensuring the accuracy of gluing. Also, according to requirements, bases with receiving grooves 12 of different sizes can be set to adapt to gluing radiators 3 of different sizes. The positioning posts 11 are arranged at one end of the upper part of the base 1. When the positioning holes 51 on the double - sided tape are sleeved on the positioning posts 11, the double - sided tape can correspond to the radiator 3, ensuring that the double - sided tape body 4 can be accurately adhered to the radiator 3, improving the product quality. When gluing, the radiator 3 is fixed through the receiving groove 12 of the base 1, and the positioning posts 11 position the double - sided tape, ensuring the precise positioning of the double - sided tape and the radiator 3. Then, the squeegee 2 is used to scrape the double - sided tape to remove air bubbles, avoiding the trouble of manual gluing, and thus improving the production efficiency. The radiator 3 is made of an aluminum substrate, and the radiator 3 can conduct, convect, or radiate heat. The glue - sticking jig of the present application is applicable to gluing radiators 3 with a nano - carbon layer and also applicable to gluing radiators 3 without a nano - carbon layer.

[0034] The working principle of the present application is as follows: During production, the base 1 is placed on the workbench. The radiator 3 to be glued is placed in the receiving groove 12. After the second release film 6 on the double - sided tape faces the radiator 3, the positioning holes 51 of the first release film 5 of the double - sided tape are sleeved on the positioning posts 11 of the base 1. Then, the worker slowly pulls the second release film 6 through the second hand - tearing position 61 on the second release film 6. At the same time, the worker holds the squeegee 2 and presses the squeegee 2 on the first release film 5, and slowly moves in the direction of tearing the second release film 6 until the second release film 6 is completely torn off and the double - sided tape body 4 is completely adhered to the surface of the radiator 3. Then, the radiator 3 is taken out and packed in a box. The first release film 5 remains on the double - sided tape body 4 and is torn off when the customer assembles the radiator 3 with the heat source.

[0035] The utility model fixes the radiator 3 through the receiving groove 12, positions the double - sided tape through the positioning posts 11, and when gluing, the squeegee 2 scrapes the double - sided tape, ensuring that the double - sided tape is accurately adhered to the radiator 3 and is not likely to generate air bubbles, thus ensuring the product quality.

[0036] As an alternative embodiment, as Figure 1 shown, an avoidance groove 13 is further provided on the base 1. The avoidance groove 13 is arranged on the side surface of the base 1, below the accommodation groove 12, and the avoidance groove 13 communicates with the accommodation groove 12. Specifically, arranging the avoidance groove 13 on the side surface of the base 1 facilitates the user to grab the radiator 3 in the accommodation groove 12, thereby facilitating the grasping and blanking of the radiator 3 after the gluing is completed. The avoidance groove 13 is arranged below the accommodation groove 12, which is convenient for the user's hand to extend into the avoidance groove 13 to grab the radiator 3 in the accommodation groove 12. The avoidance groove 13 communicates with the accommodation groove 12, so that the hand extending into the avoidance groove 13 can contact the radiator 3 in the accommodation groove 12.

[0037] As an alternative embodiment, as Figure 1 shown, the number of the avoidance grooves 13 is two, and the two avoidance grooves 13 are symmetrically arranged on both sides of the base 1. Specifically, the number of the avoidance grooves 13 is two, arranged at the upper part of the base 1 and symmetrically arranged on both sides of the base 1, which is beneficial for the user to grab the radiator 3 in the accommodation groove 12.

[0038] As an alternative embodiment, as Figure 2 shown, the depth of the accommodation groove 12 is less than the thickness of the radiator 3. Specifically, since the area of the double-sided adhesive body 4 is slightly larger than the area of the surface of the radiator 3, if the depth of the accommodation groove 12 is greater than or equal to the thickness of the radiator 3, when gluing, it is easy to paste the edge of the double-sided adhesive body 4 on the base 1, resulting in inconvenient blanking. Therefore, the depth of the accommodation groove 12 is set to be less than the thickness of the radiator 3, so that the double-sided adhesive body 4 is not easily pasted on the base 1, facilitating the blanking of the radiator 3 after the gluing is completed.

[0039] As an alternative embodiment, as Figure 2 shown, the number of the positioning posts 11 is more than one. Specifically, the number of the positioning posts 11 is preferably two or three. Multiple positioning posts 11 can ensure the stability of the double-sided adhesive when installed and positioned on the base 1. The number of the positioning posts 11 is the same as the number of the positioning holes 51 on the double-sided adhesive, ensuring that the double-sided adhesive can be assembled onto the base 1 without affecting the pasting effect of the double-sided adhesive.

[0040] As an alternative embodiment, as Figure 3 and Figure 4As shown in the figure, the structure of the squeegee 2 is a rectangular flat plate structure, and one end of the squeegee 2 is arc-shaped. Specifically, the squeegee 2 with a rectangular flat plate structure is convenient for the user to hold and perform the scraping action. Setting one end of the squeegee 2 as arc-shaped is beneficial for scraping and will not scratch the first release film 5 and / or the double-sided adhesive body 4 when the user performs the scraping action, which is used to ensure the quality of the product. When applying the adhesive to the radiator 3, by performing the scraping action with the squeegee 2, air bubbles can be avoided, and the thermal conductivity and bonding stability of the double-sided adhesive can be ensured, thereby ensuring the quality of the product.

[0041] Embodiment 2:

[0042] As Figure 5 shown, a double-sided adhesive is applied to the adhesive application fixture of Embodiment 1, and includes a double-sided adhesive body 4, a first release film 5 and a second release film 6. The first release film 5 is disposed on the first side of the double-sided adhesive body 4, and the second release film 6 is disposed on the second side of the double-sided adhesive body 4. The first release film 5 is provided with positioning holes 51 that are mutually matched and corresponding to the positioning posts 11, and the double-sided adhesive is fixed on the adhesive application fixture through the positioning holes 51. When applying the adhesive, the bottom surface of the double-sided adhesive is bonded to the corresponding radiator 3 through the adhesive application fixture. Specifically, the first release film 5 and the second release film 6 are disposed on both sides of the double-sided adhesive body 4, and the double-sided adhesive body 4 is protected by the first release film 5 and the second release film 6, and the first release film 5 and the second release film 6 are torn off only when the double-sided adhesive is used, so as to ensure the adhesiveness of the double-sided adhesive body 4. The positioning holes 51 on the first release film 5 are mutually matched and correspond one by one with the positioning posts 11 on the base 1, which is convenient for the double-sided adhesive to be sleeved on the positioning posts 11 through the positioning holes 51, realizing the precise positioning of the double-sided adhesive, and can prevent the double-sided adhesive from being pasted crookedly, improving the quality of the product.

[0043] As an optional implementation manner, the first release film 5 includes a first tear position 52, the second release film 6 includes a second tear position 61, the first tear position 52 and the second tear position 61 correspond to each other, the positioning holes 51 are disposed on the first tear position 52, and both the first release film 5 and the second release film 6 are transparent films or non-transparent films. Specifically, both the first tear position 52 and the second tear position 61 protrude outside the double-sided adhesive body 4, which is convenient for the user to tear off the first release film 5 from the double-sided adhesive body 4 through the first tear position 52 and tear off the second release film 6 from the double-sided adhesive body 4 through the second tear position 61. The positioning holes 51 are disposed on the first tear position 52. During production and processing, it is convenient for the first tear position 52 to be sleeved on the positioning posts 11 through the positioning holes 51, and it does not affect tearing off the second release film 6 during the process of bonding the double-sided adhesive to the radiator 3. The first release film 5 and the second release film 6 can be transparent films or release films of other forms or materials. The transparent release film is convenient for observing the adhesive application situation of the double-sided adhesive body 4, and it can be checked whether the adhesive application of the radiator 3 is accurate.

[0044] As an alternative embodiment, the area of the double-sided adhesive body 4 is larger than the area of the surface of the radiator 3 to which it is adhered. Specifically, generally the area of the double-sided adhesive body 4 is slightly larger than that of the radiator 3, so as to ensure that the double-sided adhesive body 4 fully covers the surface of the radiator 3, ensuring that the double-sided adhesive body 4 can conduct heat well to the radiator 3 during use.

[0045] As an alternative embodiment, the material of the double-sided adhesive body 4 is a heat-conducting material, and glue for bonding is coated on both sides of the double-sided adhesive body 4. Specifically, the material of the double-sided adhesive body 4 is a heat-conducting material, which is convenient for conducting the heat generated by the heat source to the radiator 3 through the double-sided adhesive body 4 for heat dissipation treatment. The material of the double-sided adhesive body 4 can be materials such as heat-conducting silica gel, which has good heat conductivity and can further accelerate the dissipation of heat and improve the heat dissipation performance of the radiator 3. Glue for bonding is coated on both sides of the double-sided adhesive body 4, which is convenient for bonding the double-sided adhesive body 4 to the radiator 3 after removing the second release film 6 on the double-sided adhesive body 4; after removing the first release film 5 on the double-sided adhesive body 4, the radiator 3 with the double-sided adhesive can be fixed to the heat source through the double-sided adhesive body 4.
