Description

Technical Field

[0001] The utility model relates to the field of mobile phone production and processing equipment, and particularly relates to a two-way film scraping and bubble removing mechanism for graphite sheet lamination. Background Technique

[0002] The heat-conducting graphite sheet is a thin and light heat-conducting material, which can effectively reduce the heat of the heat source to achieve large-area and rapid heat transfer, large-area heat dissipation, and eliminate the phenomenon of single-point high temperature. The heat-conducting graphite sheet is also called a heat-conducting isothermal sheet. The product thickness provides diversification, and the appearance can be die-cut into different shapes, which is convenient to be applied in various different products, especially electronic products with space constraints.

[0003] In the current mobile phone production process, it is necessary to attach the graphite sheet. To ensure the attachment quality, it is necessary to scrape the bubbles attached to the graphite sheet. For graphite sheets of different sizes and types, different scraping heads need to be used. However, the existing scraping heads are inconvenient to disassemble and assemble. At present, the pressure holding of graphite sheets and similar materials is usually operated manually or with fixtures, resulting in low production efficiency and production quality. Therefore, a two-way film scraping and bubble removing mechanism for graphite sheet lamination is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a two-way film scraping and bubble removing mechanism for graphite sheet lamination, in which the bubble scraping plate can be quickly disassembled and assembled, adapt to the film scraping and bubble removing of graphite sheets of different specifications, and can automatically scrape the film from two directions, improving the production efficiency and production quality.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A two-way film scraping and bubble removing mechanism for graphite sheet lamination, including a three-axis moving module. A seat plate is fixedly connected to the moving table of the three-axis moving module. A bracket is slidably connected to the seat plate, and a pressure sensor is fixedly connected to the bracket. A first spring is arranged between the bracket and the seat plate. A connecting seat and a cylinder are fixedly connected to the lower part of the bracket. Connecting plates are fixedly connected to the lower part of the connecting seat and the sliding table of the cylinder respectively. A bubble scraping component is arranged below each connecting plate. The bubble scraping component includes a hinge seat, a fixed claw, a second spring and a bubble scraping plate. The fixed claw is hinged to the hinge seat. The second spring is located between the fixed claw and the hinge seat. The bubble scraping plate is detachably connected to the fixed claw through a screw.

[0006] Further, the pressure sensor is located between the seat plate and the bracket, and the first spring is sleeved on the bracket.

[0007] Further, the two bubble scraping components are perpendicular to each other in their extending directions. The lower end of the fixed claw is in a U shape, and a connecting hole is opened at the end of the fixed claw.

[0008] Furthermore, a triangular protrusion is provided at the lower end of the bubble scraper.

[0009] The beneficial effects of the utility model are: through the coordinated use of the three-axis moving module, the bracket, the cylinder and the bubble scraping assembly, the bubble scraper can be quickly disassembled and assembled, adapted to the scraping and bubble removal of graphite sheets of different specifications, and can automatically scrape the film from two directions, thereby improving production efficiency and production quality.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] refer to Figure 1-Figure 4 The shown embodiment is a bidirectional scraping and bubble removal mechanism for graphite sheet lamination, comprising a three-axis movable module 1, a seat plate 101 being fixedly connected to the movable platform of the three-axis movable module 1, a bracket 2 being slidably connected to the seat plate 101, a pressure sensor 201 being fixedly connected to the bracket 2, a first spring 202 being arranged between the bracket 2 and the seat plate 101, the first spring 202 being used to reset the bracket 2, a connecting seat 3 and a cylinder 4 being fixedly connected to the lower part of the bracket 2, a connecting plate 5 being fixedly connected to the lower part of the connecting seat 3 and the sliding platform of the cylinder 4, a bubble scraping assembly being arranged at the lower part of each connecting plate 5, the bubble scraping assembly comprising a hinge seat 601, a fixed claw 602, a second spring 603 and a bubble scraper 604, the fixed claw 602 being hinged to the hinge seat 601, the second spring 603 being located between the fixed claw 602 and the hinge seat 601, the bubble scraper 604 being detachably connected to the fixed claw 602 via a screw.

[0017] The pressure sensor 201 is located between the seat plate 101 and the bracket 2. The first spring 202 is sleeved on the bracket 2. The pressure sensor 201 is used to monitor the pressure value of the bubble squeegee 604 on the graphite sheet, so as to avoid damaging the product due to excessive pressure.

[0018] The two bubble scraping assemblies are perpendicular to each other in their extending directions. The two bubble scraping assemblies can scrape the graphite sheet from two directions. The lower end of the fixed claw 602 is in a U shape, and a connection hole is opened at the end of the fixed claw 602.

[0019] The lower end of the bubble squeegee 604 is provided with a triangular protrusion. When scraping the film, the triangular protrusion contacts the graphite sheet for film scraping treatment, so as to improve the film scraping effect.

[0020] The working principle of the present utility model is as follows: When the present utility model is in use, a suitable bubble squeegee 604 is selected according to the graphite sheet that needs to be film pasted and bubble scraped and installed on the fixed claw 602. When performing film scraping treatment, first, the bubble scraping assembly at the connecting seat 3 is driven by the three-axis moving module 1 to vertically press down on one end of the graphite sheet and then translate for film scraping treatment. After the film scraping in this direction is completed, the bubble squeegee 604 moves upward. Then, the piston rod of the cylinder 4 extends, and the bubble scraping assembly at the cylinder 4 descends to the lower part of the bubble scraping assembly at the connecting seat 3, and the above-mentioned film scraping action is repeated to perform film scraping treatment from another direction, so as to complete the film scraping and bubble removing treatment in two directions on the plane of the graphite sheet.

[0021] The above embodiments are used to further illustrate the present utility model, but do not limit the present utility model to these specific embodiments. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be understood to be within the protection scope of the present utility model.
