Description

Technical Field

[0001] The utility model relates to the technical field of texture processing, in particular to a grid texture processing device for a hinge shell. Background Art

[0002] Smartphones are being upgraded rapidly, and existing flat-type phones can no longer meet the needs of the majority of people. Folding phones have entered the market one after another. When folding folding phones, a hinge shell is needed to protect the hinge. In order to adapt to the appearance and prevent slipping, texture is usually added to the hinge shell. The general texture is grid-shaped. In the processing of the grid texture, commonly used equipment first performs the first type of twill processing from the upper left to the lower right, and then performs the second type of twill processing from the upper right to the lower left. The directions and angles of the two types of twill processing are just opposite, so two sets of linear modules are used to complete it, which leads to a larger equipment size, high processing cost, and low efficiency.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] like Figures 1 to 4As shown, in this embodiment, a grid texture processing device for a hinge shell includes an equipment bracket 1, a jig mounting table 2, a transverse mounting frame 3, a vertical linear module 4 and a processing turntable 5. The jig mounting table 2 moves inside the equipment bracket 1 along the front-to-back direction, and a shell positioning plate 6 is fixed on the jig mounting table 2. A shell cavity 18 is provided in the middle of the shell positioning plate 6. The transverse mounting frame 3 moves laterally at the upper end of the equipment bracket 1, the vertical linear module 4 is fixed on the transverse mounting frame 3, and the processing turntable 5 is rotatably connected to the lower end of the vertical linear module 4. A cutter head 7 is fixed at the edge of the processing turntable 5.

[0021] During processing, the hinge shell 17 is placed in the shell cavity 18, and the processing turntable 5 is started. During the rotation process, the processing turntable 5 drives the cutter head 7 to rotate in a circular motion. Under the action of the transverse mounting frame 3 and the vertical linear module 4, the processing turntable 5 is driven to move left and right and up and down, and the front and back movement of the jig mounting table 2 drives the hinge shell 17 to move back and forth, so the processing turntable 5 can be accurately aligned with the position on the hinge shell 17 that needs to be processed.

[0022] When the processing turntable 5 rotates counterclockwise, the cutter head 7 first contacts the left side of the hinge shell 17. According to the pre-set speed, the processing turntable 5 moves forward at the right position of the hinge shell 17, and the cutter head 7 moves circularly from the left side of the hinge shell 17 to the right side of the hinge shell 17. Combined with the forward movement of the processing turntable 5, the movement trajectory of the cutter head 7 on the hinge shell 17 is a linear first-type twill 15 (the trajectory is from the upper left to the lower right). After processing several groups of mutually parallel first-type twills 15, the processing turntable 5 is driven by the transverse mounting frame 3 and moves forward to the left position of the hinge shell 17. Without changing the direction of the processing turntable 5, combined with the forward movement of the processing turntable 5, the movement trajectory of the cutter head 7 on the hinge shell 17 is a linear second-type twill 16 (the trajectory is from the lower left to the upper right), thereby forming a grid texture.

[0023] A transverse motor is installed on the equipment bracket 1, and the driving end of the transverse motor is connected to the transverse screw 8. The rear end of the transverse mounting frame 3 is fixed with a transverse nut seat. The transverse screw 8 is threadedly connected to the transverse nut seat. The transverse motor controls the rotation of the transverse screw 8, and the transverse mounting frame 3 with the transverse nut seat drives the processing turntable 5 to move left and right.

[0024] A processing protection cover 9 is fixed to the lower end of the vertical linear module 4 , and the processing protection cover 9 covers the front end of the processing turntable 5 . The processing protection cover 9 effectively blocks flying debris when the cutter head 7 processes the hinge housing 17 .

[0025] A negative pressure cavity 10 is provided on the fixture mounting plate, and a plurality of negative pressure holes 11 are provided on the shell positioning plate 6. The negative pressure holes 11 connect the shell cavity 18 with the negative pressure cavity 10. Under the negative pressure of the negative pressure cavity 10, the hinge shell 17 can be adsorbed in the shell cavity 18 and will not move around.

[0026] Positioning screws 12 are provided around the shell positioning plate 6. The positioning screws 12 pass through the shell positioning plate 6 and are threadedly connected to the fixture mounting plate. Different shell positioning plates 6 can be replaced according to different hinge shells 17. The change can be achieved by loosening the positioning screws 12.

[0027] A product positioning plate 13 is provided in the middle of the shell positioning plate 6, and a positioning hole is provided on the product positioning plate 13. A positioning pin 14 is provided on the shell positioning plate 6, and the positioning pin 14 is inserted into the positioning hole. The product positioning plate 13 further limits the outer position of the hinge shell 17 to be fixed on the inner side of the product positioning plate 13, and the processing accuracy is improved. At the same time, it is more convenient to replace the product positioning plate 13 under the action of the positioning pin 14.

[0028] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be included in the scope of protection of the present invention.
