Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a fixing device that can be applied to the pre-bonding of screen and cover glass. Background Technology

[0002] The screen and cover glass of electronic devices need to be bonded together. Before being fully bonded, the screen and cover glass need to be aligned, pre-bonded, and then fed into a bonding mechanism for final bonding. CN105946331A discloses a touch screen bonding device, which has several adhesive suction cups on a vacuum suction plate. The adhesive suction cups are used to prevent the touch screen from jumping during the vacuuming operation of the vacuum suction plate. However, the adhesive suction cups continuously pick up the touch screen, and after bonding, the touch screen is difficult to remove from the vacuum suction plate, which may even cause the touch screen to separate from the display screen or generate air bubbles. Utility Model Content

[0003] Therefore, this utility model needs to provide a fixing device that can be used to fix two products when they are attached together, and makes it easy for the products to leave the fixing device after they are attached.

[0004] This utility model provides a fixing device, the fixing device comprising:

[0005] The first bearing fixture has a first bearing surface, a first negative pressure hole leading to the first bearing surface, and a receiving groove in the middle of the first bearing fixture.

[0006] The second bearing fixture has a second bearing surface and a second negative pressure hole that leads to the second bearing surface. The second bearing fixture is placed in the receiving groove.

[0007] Furthermore, the first support fixture is provided with a chamber and a negative pressure interface, the chamber being connected to the first negative pressure hole and the negative pressure interface.

[0008] Furthermore, the area of ​​the second bearing surface is smaller than the area of ​​the first bearing surface.

[0009] Furthermore, the second bearing surface is elongated.

[0010] Furthermore, at least one side of the second bearing surface is chamfered.

[0011] Furthermore, the chamfer is provided on the long side of the second bearing surface.

[0012] Furthermore, the first support fixture is provided with a positioning edge.

[0013] Furthermore, the second bearing fixture includes an elastic body, the second bearing surface is located on the elastic body, and the elastic body is provided with the second negative pressure hole.

[0014] The advantages of this utility model are as follows: This utility model includes a first support fixture and a second support fixture. One way of using it is that the first support fixture and the second support fixture can be used to initially fix a product. After the product is initially fixed, it is then fixed by both the first support fixture and the second support fixture. When another product is aligned with the first product for bonding, the negative pressure of the first support fixture is removed, and the second support fixture is used to fix the product, so that the two products can be bonded together. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure 2 for Figure 1 A schematic diagram of its breakdown. Detailed Implementation

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] This utility model provides a fixing device, see the specific embodiments described herein. Figure 1 As shown, the fixing device includes a first supporting fixture 10 and a second supporting fixture 20.

[0019] The first support fixture 10 has a first support surface 11, a first negative pressure hole 12 leading to the first support surface 11, and a receiving groove 13 in the middle of the first support fixture 10. The second support fixture 20 has a second support surface 21, a second negative pressure hole 22 leading to the second support surface 21, and is placed in the receiving groove 13.

[0020] The first support fixture 10 is provided with a positioning edge 14, which is used to position the screen when placing, for example, a screen.

[0021] One of the ways in which this utility model is used is as follows: one of the first support fixture 10 and the second support fixture 20 can be used as the initial fixation of a product. After the product is initially fixed, it is then fixed by the first support fixture 10 and the second support fixture 20 at the same time. When another product is aligned with the product and then pasted together, the negative pressure of the first support fixture 10 is removed, and the second support fixture 20 is used to fix the product so that the two products can be pasted together.

[0022] See Figure 2 As shown, the first support fixture 10 is provided with a chamber 15 and a negative pressure interface 16. The chamber 15 is connected to the first negative pressure hole 12 and the negative pressure interface 16. The negative pressure interface 16 is connected to a negative pressure mechanism, thereby forming a negative pressure in the chamber 15, and subsequently forming a negative pressure at the first negative pressure hole 12. The first support fixture 10 may include a base 101 and a cover plate 102. The cover plate 102 is provided with the first negative pressure hole 12, and the cover plate 102 is placed on the base 101 to form the chamber 15.

[0023] The area of ​​the second bearing surface 21 is smaller than the area of ​​the first bearing surface 11. In this embodiment, the second bearing surface 21 is elongated. At least one side of the second bearing surface 21 forms a chamfer 211, which is preferably located on the long side of the second bearing surface 21, and may be two long sides. While ensuring the structural strength of the second bearing fixture 20, the area of ​​the second bearing surface 21 can be reduced. During initial fixing, the second bearing fixture 20 is used to fix a product. When the first bearing fixture 10 and the second bearing fixture 20 fix the product simultaneously, the first bearing fixture 10 is used as much as possible to adsorb and fix the product. When another product is attached to the product, the second bearing fixture 20 is used to fix the product. This reduces the contact area between the second bearing fixture 20 and the product, allowing the uncontacted portion to better adhere to the other part of the product.

[0024] The second bearing fixture 20 includes an elastic body 201, the second bearing surface 20 is located on the elastic body 201, and the elastic body 201 is provided with the second negative pressure hole 22. The elastic body 201 can provide elastic buffer protection for the products when the two products are attached to each other.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
