Description

Technical Field

[0001] The utility model relates to the field of electronic product mounting, in particular to a film pasting device for a mobile phone back cover. Background Art

[0002] When people place their mobile phones, in order to avoid scratching the mobile phone screen, they usually place the mobile phone back cover on a support surface, which makes the mobile phone back cover vulnerable to scratching, abrasion and scuffing. People often neglect to protect the mobile phone back cover. The damage of the mobile phone back cover also affects the overall beauty and the feel of using the mobile phone. Generally, a film is pasted on the mobile phone back cover. A film pasting device is disclosed in the Chinese utility model patent with the publication number CN210822960U, which can accurately position the film pasting mechanism in multiple directions to improve the film pasting quality. At the same time, a circulating conveying mechanism is adopted to continuously convey the mobile phone back cover to the film pasting mechanism, improving the film pasting production efficiency. For some mobile phone back covers, the four edges on the surface are all bent upwards to form arc-shaped side edges. The existing film pasting mechanism in the structure can only paste the horizontal part of the mobile phone back cover surface, which results in that the four arc-shaped sides of the mobile phone back cover cannot be pasted, and secondary pasting is required. Therefore, we have designed a film pasting device for a mobile phone back cover. Summary of the Utility Model

[0003] To solve the technical problem that the four arc-shaped sides of the mobile phone back cover cannot be pasted and secondary pasting is required, the utility model provides a film pasting device for a mobile phone back cover.

[0004] The utility model is realized by adopting the following technical solutions: A film pasting device for a mobile phone back cover includes a machine table. A conveying mechanism and a film pasting mechanism are installed above the machine table. A moving plate is placed on the conveying mechanism. A fixture is fixed on the moving plate. A mobile phone back cover is placed upside down on the fixture. The conveying mechanism includes a first conveyor belt and a second conveyor belt. The moving plate is located between the first conveyor belt and the second conveyor belt. There is a gap between the first conveyor belt and the second conveyor belt, and a positioning mechanism is installed on the left side of the gap through a bracket.

[0005] An installation frame in a Z-shaped structure is installed on the upper left rear side of the machine table. A film combining cylinder is installed on the installation frame. The push rod of the film combining cylinder is located below the installation frame and is equipped with a pressing fixture. The pressing fixture is directly above the mobile phone back cover.

[0006] As a further improvement of the above solution, the positioning mechanism includes a positioning cylinder, which is installed between the first conveyor belt and the second conveyor belt through a bracket, and the positioning cylinder is located on the left side of the pressing fixture. A positioning block is also provided on the push rod of the positioning cylinder. Under the action of the positioning cylinder, the positioning block is above the belts of the first conveyor belt and the second conveyor belt, and it can block the moving plate, so that the moving plate cannot continue to move under the action of the first conveyor belt and the second conveyor belt, and the mobile phone back cover above it can be positioned directly below the pressing fixture, so that the film on the mobile phone back cover can be completely adhered.

[0007] As a further improvement of the above solution, a separating cylinder is installed between the first conveyor belt and the second conveyor belt through a bracket, and the separating cylinder is located on the right side of the pressing fixture. A separating block is installed on the push rod of the separating cylinder. After the positioning block blocks the mobile phone back cover that needs film adhesion, the separating block can move upward so that the subsequent moving plate will not contact the leftmost moving plate, and a certain distance is formed between the two moving plates, which is convenient for the positioning block to block the moving plate that needs film adhesion and improves the accuracy of film adhesion.

[0008] As a further improvement of the above solution, the positioning cylinder and the separating cylinder are controlled to lift by two independent external power supplies. When the positioning block contacts the right side surface of the moving plate, the pressing fixture is directly above the mobile phone back cover above the moving plate. The positioning cylinder and the positioning block can position the pressing fixture, so that the mobile phone back cover above the moving plate is located below the pressing fixture, which is convenient for pressing the four edges of the film to cover the four arc-shaped edges of the mobile phone back cover.

[0009] As a further improvement of the above solution, the length and width of the pressing fixture match the length and width of the mobile phone back cover, and the depth of the pressing fixture is not less than the height of the mobile phone back cover. The length and width of the film adhered to the mobile phone back cover are greater than the length and width of the pressing fixture, and the film can be covered on the surface of the mobile phone back cover under the action of the pressing fixture.

[0010] As a further improvement of the above solution, the four edges at the bottom end of the pressing fixture are designed with rounded corners to form a semi-circular contact arc surface, and the shape of the top end inside the pressing fixture is exactly the same as the shape of the top of the mobile phone back cover, which can ensure that the film with raised edges around is completely covered.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The utility model is provided with a film combining cylinder above the machine table, and a pressing fixture is installed below the film combining cylinder. Cooperating with the provided positioning mechanism, the pressing fixture is directly above the mobile phone back cover after the film is attached, and it can press the four edges of the film so that it covers the four arc-shaped edges of the mobile phone back cover, thereby enabling the film to be attached to the arc-shaped edges of the mobile phone back cover;

[0013] 2. By providing a separating cylinder and a separating block on the right side of the film combining cylinder, it can ensure that there is a certain distance between the two mobile phone back covers, enabling the positioning mechanism to position each mobile phone back cover separately, thereby improving the accuracy of film attachment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, in combination with the drawings and the specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following-described embodiments or technical features to form a new embodiment.

[0022] Embodiment:

[0023] Please combine with Figures 1 - 5, A mobile phone back cover film sticking device of this embodiment includes a machine table 1. Above the machine table 1, a conveying mechanism 2 and a film sticking mechanism 4 are installed. A moving plate 3 is placed on the conveying mechanism 2. A fixture 31 is fixed on the moving plate 3. A mobile phone back cover 7 is placed upside down on the fixture 31. The conveying mechanism 2 includes a first conveyor belt 21 and a second conveyor belt 22. The moving plate 3 is located between the first conveyor belt 21 and the second conveyor belt 22. There is a gap between the first conveyor belt 21 and the second conveyor belt 22. And a positioning mechanism 9 is installed on the left side of this gap through a bracket.

[0024] On the upper left rear side of the machine table 1, a Z-shaped mounting frame 51 is installed. A film combining cylinder 5 is installed on the mounting frame 51. The push rod of the film combining cylinder 5 is below the mounting frame 51 and a pressing fixture 6 is installed. The pressing fixture 6 is directly above the mobile phone back cover 7.

[0025] The positioning mechanism 9 includes a positioning cylinder. The positioning cylinder is installed between the first conveyor belt 21 and the second conveyor belt 22 through a bracket. And the positioning cylinder is on the left side of the pressing fixture 6. A positioning block is also arranged on the push rod of the positioning cylinder. Under the action of the positioning cylinder, the positioning block is above the belts of the first conveyor belt 21 and the second conveyor belt 22. It can block the moving plate 3, so that the moving plate 3 cannot continue to move under the action of the first conveyor belt 21 and the second conveyor belt 22, and the mobile phone back cover 7 above it can be directly below the pressing fixture 6, so that the film 71 on the mobile phone back cover 7 can be completely adhered.

[0026] A separating cylinder 8 is installed between the first conveyor belt 21 and the second conveyor belt 22 through a bracket. And the separating cylinder 8 is on the right side of the pressing fixture 6. A separating block 81 is installed on the push rod of the separating cylinder 8. After the positioning block blocks the mobile phone back cover 7 that needs film combining, the separating block 81 can move upward so that the subsequent moving plate 3 will not contact the leftmost moving plate 3, making there a certain distance between the two moving plates 3, thus facilitating the positioning block to block the moving plate 3 that needs film combining and improving the film combining accuracy.

[0027] The positioning cylinder and the separating cylinder 8 are controlled to lift by two independent external power supplies. And when the positioning block contacts the right side surface of the moving plate 3, the pressing fixture 6 is directly above the mobile phone back cover 7 on this moving plate 3. The positioning cylinder and the positioning block can position the pressing fixture 6, so that the mobile phone back cover 7 above the moving plate 3 is below the pressing fixture 6, thus facilitating the pressing of the four edges of the film 71 to cover the four arc-shaped edges of the mobile phone back cover 7.

[0028] The length and width of the pressing fixture 6 match the length and width of the mobile phone back cover. And the depth of the pressing fixture 6 is not less than the height of the mobile phone back cover 7. The length and width of the film 71 adhered to the mobile phone back cover 7 are greater than the length and width of the pressing fixture 6. The film 71 can be covered on the surface of the mobile phone back cover 7 under the action of the pressing fixture 6.

[0029] At the four edges of the bottom end of the lamination fixture 6, fillets are designed to form a contact arc surface 61 with a semi-circular structure, and the shape of the top end inside the lamination fixture 6 is exactly the same as the shape of the top of the mobile phone back cover 7, which can ensure that the film 71 with raised edges all around is completely covered.

[0030] The implementation principle of a mobile phone back cover film pasting device in an embodiment of the present application is as follows: during actual use, the mobile phone back cover 7 is buckled on the fixture 31 and moves leftward under the action of the conveying mechanism 2. When it passes under the film pasting mechanism 4, the film 71 will adhere to the surface of the mobile phone back cover 7, and the four edges of the film 71 are in a raised state because they are not covered on the arc-shaped edges around the mobile phone back cover 7 (as Figure 5 shown). The positioning cylinder in the positioning mechanism 9 makes the positioning block move upward. When the moving plate 3 contacts the positioning block, the mobile phone back cover 7 is directly below the lamination fixture 6 at this time. The push rod of the film combining cylinder 5 makes the lamination fixture 6 move downward and presses the lamination fixture 6 above the mobile phone back cover 7, so as to press the four edges of the film 71, making it cover the four arc-shaped edges of the mobile phone back cover 7. Then the positioning block moves downward and makes the film-combined moving plate 3 continue to move leftward, and the positioning block moves upward again and waits for the film combining of the next mobile phone back cover 7;

[0031] By arranging a film combining cylinder 5 above the machine table 1, and installing a lamination fixture 6 below the film combining cylinder 5, and cooperating with the arranged positioning mechanism 9, the lamination fixture 6 is directly above the mobile phone back cover 7 after the film 71 is pasted. It can press the four edges of the film 71, making it cover the four arc-shaped edges of the mobile phone back cover 7, so that the arc-shaped edges of the mobile phone back cover 7 can be processed with the film 71 pasted;

[0032] By arranging a separating cylinder 8 and a separating block 81 on the right side of the film combining cylinder 5, it can ensure that there is a certain distance between two mobile phone back covers 7, so that the positioning mechanism 9 can position each mobile phone back cover 7 separately, thereby improving the accuracy of film pasting 71.

[0033] The above-mentioned implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model belong to the scope of protection required by the present utility model.
