Description

Technical Field

[0001] This invention relates to equipment for feeding mobile phone glass covers, and more particularly to a mobile phone glass cover feeding machine. Background Technology

[0002] In the mobile phone manufacturing process, the processing of the glass cover is a crucial step. The loading process of the glass cover directly affects the efficiency of subsequent processing and product quality. Mobile phone glass cover loading is mostly accomplished using automated loading equipment. Its structure can be referenced in Chinese Utility Model Patent Publication No. CN216302609U, entitled "Mobile Phone Glass Cover Loading Machine," and Chinese Utility Model Patent Publication No. CN210438061U, entitled "A Fully Automated Loading Device for CNC Machining of Mobile Phone Glass Back Cover." In the mobile phone glass cover loading process, dust is one of the core contaminants affecting the quality of subsequent processing steps. If dust adheres to the glass surface or gets mixed into the loading equipment, it may cause problems such as impurities, coating peeling, and reduced light transmittance on the cover. Dust particles (especially those with a diameter > 0.05mm) adhering to the glass surface, if not cleaned properly, will solidify inside or on the surface of the glass during subsequent high-temperature melting, coating, or screen printing processes, forming visible impurities and directly leading to product appearance defects (industry standards require that the cover surface be free of visible impurities). Dust can damage the adhesion between the coating layer and the glass surface. For example, if there is dust on the glass surface before magnetron sputtering coating, the coating layer is prone to "pinholes" or "peeling," leading to the failure of anti-fingerprint and anti-reflective functions. Simultaneously, if dust mixes with raw materials or molten glass, it will affect the uniformity of the glass and reduce the cover's impact resistance. If dust contamination is found after a certain process, the completed process needs to be disassembled and reprocessed (e.g., cleaning dust after screen printing requires removing the cured ink and re-screen printing), which not only increases production costs but may also cause glass edge cracking or excessive thickness deviation due to secondary processing. Therefore, strict dust cleaning must be carried out in the loading process before many processing steps. Although existing mobile phone glass cover loading equipment has a solution of setting up an air shower at the inlet to quickly remove dust adhering to the product surface, this method not only affects the continuity of the loading operation but also has the drawback of cleaning dead corners.

[0016] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figures 1 to 8 As shown, a mobile phone glass cover plate feeding machine of the present invention includes: The tunnel-type feeding shell 1 is hollow inside and has an inlet 11 and an outlet 12 at both ends. The tunnel cavity of the tunnel-type feeding shell 1 is provided with a feeding guide rail 13 along the axial direction, and a rack 131 is provided on one side wall of the feeding guide rail 13. The feeding plate 2 is rotatably arranged inside the tunnel cavity around the axis of the tunnel-type feeding shell 1, and the edge of the feeding plate 2 is provided with a spiral feeding track 21. The mobile phone glass cover vertical clamp 3 is provided with a gear 31 that meshes with the rack 131. The spiral feeding track 21 pushes the mobile phone glass cover vertical clamp 3 to move along the feeding guide 13 toward the side where the discharge port 12 is located. The mobile phone glass cover vertical clamp 3 rotates during movement through the meshing of the rack 131 and the gear 31. Fan 4 delivers air into the tunnel cavity from the inlet 11 or the outlet 12.

[0018] The working principle described above is as follows: During operation, the vertical clamp 3 for mobile phone glass covers is fed into the feeding guide rail 13 inside the tunnel cavity from the inlet 11 of the tunnel. The fan 4 is started, and at the same time, the loading plate 2 inside the tunnel cavity is controlled to rotate in one direction at a uniform speed. When the spiral feeding track 21 on the edge of the loading plate 2 contacts the vertical clamp 3 for mobile phone glass covers, it will push the vertical clamp 3 for mobile phone glass covers to move. Under the meshing action of the gear 31 and the rack 131, the vertical clamp 3 for mobile phone glass covers will rotate while moving linearly along the feeding guide rail 13. This causes the wind-receiving surface, wind-receiving angle, and wind-receiving pressure of the mobile phone glass cover clamped on it to change continuously throughout the feeding process, so as to achieve the purpose of continuous, multi-angle air blowing cleaning.

[0019] The beneficial effects described above are as follows: The core concept of this mobile phone glass cover plate feeding machine is that it can perform multi-angle complete cleaning during the continuous feeding process of mobile phone glass cover plates. The feeding machine mainly adopts a semi-enclosed, tunnel-type feeding type, including an external tunnel-type feeding shell 1 and a fan 4, as well as a feeding plate 2 and a vertical clamping fixture for mobile phone glass cover plates set inside the tunnel. When the mobile phone glass cover plate is continuously fed, the mobile phone glass cover plate feeding machine of this invention can perform multi-directional uniform air blowing cleaning on the glass surface, thereby improving the feeding quality of the mobile phone glass cover plate feeding machine.

[0020] In addition, in the mobile phone glass cover plate feeding machine of the present invention, the temperature and wind speed of the fan 4, the pushing speed of the spiral feeding track 21, and the rotation speed of the mobile phone glass cover plate vertical clamp 3 can all be flexibly adjusted according to the corresponding process. For example, in the physical strengthening stage of the mobile phone glass cover plate, after the glass body is heated, it needs to enter the cold air equipment for rapid and uniform cooling. Using this feeding device, the mobile phone glass cover plate can be cooled quickly and uniformly, so that the surface of the mobile phone glass cover plate is cooled rapidly and uniformly, and the interior is cooled slowly, forming surface compressive stress, thereby achieving the purpose of improving the mechanical properties of the mobile phone glass cover plate.

[0030] When the friction layer 22 is made of cotton pad, the cotton pad is used to generate static electricity by rubbing the electrostatic adsorption dust removal net 14, and at the same time, it is used to clean the dust on the electrostatic adsorption dust removal net 14 into the annular dust collection groove 15, so as to avoid affecting the effect of generating charge by friction and ensure the cleanliness of the parts.

[0031] When the friction layer 22 is made of insulating and absorbent material, the electrostatic adsorption dust removal net 14 is connected to the conductive busbar. The insulating and absorbent material is designed for situations where the humidity of the glass surface or the ambient humidity is high. A humidity sensor and a temperature sensor can be installed inside the tunnel-type feeding housing 1. The controller receives the information sent by the sensor to control the fan 4 to blow hot air at a preset temperature to heat and dry the glass.

The reason for designing the vertical insertion and removal clamping port is to ensure the stability of the mobile phone glass cover clamping while facilitating the installation and removal of the mobile phone glass cover. When in use, the mobile phone glass cover is inserted into the clamping port from top to bottom and the elastic clamping arm 35 is opened.

The limit housing is provided with a notch for the upright 33 to pass through. The discharge section of the circulating feed belt 7 is equipped with a sensor counter 10 connected to the controller. The sensor counter 10 is used to monitor the quantity of mobile phone glass covers being fed.

[0045] In summary, the mobile phone glass cover plate feeding machine of the present invention adopts a semi-enclosed, tunnel-type feeding type, including an external tunnel-type feeding shell and a fan, as well as a feeding plate and a vertical clamp for the mobile phone glass cover plate set inside the tunnel. During operation, the vertical clamp for the mobile phone glass cover plate is fed into the feeding guide rail inside the tunnel cavity from the inlet of the tunnel. The fan is started, and the feeding plate inside the tunnel cavity is controlled to rotate unidirectionally at a uniform speed. When the spiral feeding track at the edge of the feeding plate contacts the vertical clamp for the mobile phone glass cover plate, it will push the vertical clamp for the mobile phone glass cover plate to move. Under the meshing action of gears and racks, the vertical clamp for the mobile phone glass cover plate will rotate while moving linearly along the feeding guide rail. This causes the wind-receiving surface, wind-receiving angle, and wind-receiving pressure of the mobile phone glass cover plate clamped on it to change continuously throughout the feeding process, so as to achieve the purpose of continuous, multi-angle air blowing cleaning. The mobile phone glass cover plate feeding machine of this invention can perform multi-directional and uniform air blowing cleaning on the glass surface during continuous feeding of mobile phone glass cover plates, thereby improving the feeding quality. The equipment is highly versatile and can be adapted to the feeding operation of mobile phone glass cover plates of all specifications. In addition, in the mobile phone glass cover plate feeding machine of this invention, the temperature and speed of the fan, the pushing speed of the spiral feeding track, and the rotation speed of the vertical clamp of the mobile phone glass cover plate can all be flexibly adjusted according to the corresponding process. For example, in the physical strengthening stage of the mobile phone glass cover plate, after the glass body is heated, it needs to enter the cold air equipment for rapid and uniform cooling. Using this feeding device, the mobile phone glass cover plate can be cooled quickly and uniformly, so that the surface of the mobile phone glass cover plate cools rapidly and uniformly, while the interior cools slowly, forming surface compressive stress, thereby achieving the purpose of improving the mechanical properties of the mobile phone glass cover plate.
