Description

Technical Field

[0001] This utility model relates to the field of film-applying fixture technology, specifically a refrigerator door handle explosion-proof film applicator. Background Technology

[0002] During the reproduction process, door handles undergo a series of treatments. Before becoming the final product, a protective film needs to be applied to the surface of the door handle to protect it.

[0003] Current handle film application devices, such as the one described in announcement number CN215285416U, include: a base, a bottom plate, a base, and a pressing assembly. The bottom of the base is recessed to form a groove. The bottom plate is detachably mounted on the bottom of the base by bolts and is used to seal the groove. The top of the base is recessed to form a storage slot for placing the door handle. There is at least one pressing assembly, which is also located in the storage slot. The pressing assembly passes through the mounting hole of the door handle and presses it into the storage slot from the top of the door handle. The bottom of the storage slot is provided with several ventilation holes communicating with the groove. The side wall of the base is provided with a connecting hole for a vacuum pump to evacuate the inside of the groove. The base is located at the bottom of the bottom plate.

[0004] The above-mentioned device uses suction negative pressure to apply the film, but it cannot fix the film during the suction application process, which easily causes misalignment and instability. Moreover, after application, the left and right ends of the product are not bonded to the film. Therefore, we have proposed a refrigerator door handle explosion-proof film application fixture to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a refrigerator door handle explosion-proof film bonding fixture to solve the problem mentioned in the background art that the existing device uses suction negative pressure to bond the film, but the film cannot be fixed during the suction bonding process, which easily causes misalignment and instability, and the left and right ends of the product have no adhesion to the film after bonding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a refrigerator door handle explosion-proof film bonding fixture, including a base plate, a first limiting frame installed at the front of the upper end of the base plate, a second limiting frame provided at the rear end of the first limiting frame, a placement groove provided between the first limiting frame and the second limiting frame, an adhesive silicone pad provided inside the placement groove, and a pressure plate provided above the adhesive silicone pad.

[0007] Preferably, the adhesive silicone pad is polished from silicone with added tackifiers and has a hardness of 60°A.

[0008] Preferably, the first limiting frame is provided with four positioning pin holes, which are equidistantly distributed.

[0009] Preferably, the second limiting frame has multiple limiting grooves inside, and a limiting block is installed inside the limiting groove. The limiting block has a through hole inside, and the limiting block is connected to the limiting groove through the through hole and a screw.

[0010] Preferably, an elastic head is installed on the end face of the limiting block, and the outer wall of the elastic head is provided with wear-resistant and anti-slip texture.

[0011] Preferably, the outer side of the base plate is provided with a plurality of first mounting holes, and the base plate is connected to the worktable through the first mounting holes and screws.

[0012] Preferably, the pressure plate is provided with a second mounting hole, and the pressure plate is connected to a pneumatic or hydraulic device through the second mounting hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting an adhesive silicone pad in the placement groove, the contact surface of the film is made of adhesive silicone during the bonding and pressing process. Under the action of adhesive force, the film can avoid displacement after being pressed. Moreover, silicone is a flexible material and can expel air bubbles after pressing, so that the film and the product can be evenly bonded. This solves the problem that the existing device uses suction negative pressure to bond the film, but the film cannot be fixed during the suction bonding process, which easily causes misalignment and instability. Furthermore, after bonding, the left and right ends of the product have no adhesion to the film.

[0015] (2) By setting positioning pins on the first limiting frame and setting corresponding positioning holes on the release paper of the film, when placing it, the positioning holes on the release paper of the film are aligned with the positioning pins in the through holes of the positioning pins of the first limiting frame. The four positioning pins are used to prevent the film from being misaligned when it is placed, thereby improving the subsequent film application accuracy. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a refrigerator door handle explosion-proof film bonding fixture, including a base plate 1, a first limiting frame 3 installed at the front of the upper end of the base plate 1, a second limiting frame 4 provided at the rear end of the first limiting frame 3, a placement groove 6 provided between the first limiting frame 3 and the second limiting frame 4, an adhesive silicone pad 7 provided inside the placement groove 6, and a pressure plate 10 provided above the adhesive silicone pad 7. The adhesive silicone pad 7 is made of silicone with added adhesion promoters and polished to a hardness of 60°A. The first limiting frame 3 is provided with positioning pin through holes 5. There are four positioning pin through holes 5, and the four positioning pin through holes 5 are evenly distributed. The outer side of the base plate 1 is provided with multiple first mounting holes 2, and the base plate 1 is connected to the workbench through the first mounting holes 2 and screws. The pressure plate 10 is provided with second mounting holes 11, and the pressure plate 10 is connected to pneumatic or hydraulic equipment through the second mounting holes 11.

[0023] When applying the explosion-proof diaphragm, the operator places the diaphragm 12 into the placement slot 6 of the fixture. The surface of the diaphragm 12 is covered with release paper 13, and four positioning holes 14 are evenly distributed on the side of the release paper 13. When placing the diaphragm 12, the positioning holes 14 on the release paper 13 are aligned with the positioning pins in the positioning pin through holes 5 of the first limit frame 3. The four positioning pins are used to prevent the diaphragm 12 from being misaligned during placement. After the position is confirmed, the release paper 13 is removed, fixing the diaphragm 12 onto the adhesive silicone pad. Then, the handle to be covered is placed into the placement slot 6, and the pressure plate 10 moves down under hydraulic or pneumatic action. With the help of the pressure sensor, a certain amount of pressure is applied to make the diaphragm 12 adhere to the handle. During the pressing process, because the contact surface of the diaphragm 12 is adhesive silicone, the adhesive force can prevent the diaphragm from shifting after being pressed. Moreover, silicone is a flexible material, which can expel air bubbles after pressing, so that the diaphragm and the product can be evenly adhered.

[0024] Please see Figure 1 and Figure 3The second limiting frame 4 has multiple limiting grooves 8 inside, and limiting blocks 9 are installed inside the limiting grooves 8. The limiting blocks 9 have through holes 901 inside, and the limiting blocks 9 are connected to the limiting grooves 8 through the through holes 901 and screws. An elastic head 902 is installed on the end face of the limiting block 9. The outer wall of the elastic head 902 is provided with wear-resistant and anti-slip textures 903. The specifications of the limiting block 9 can be adjusted according to the width of the handle, thereby fine-tuning the lateral positioning distance. The elasticity of the elastic head 902 makes the handle more stable.
