Technical Field

[0001] The utility model relates to the technical field of surface hanging treatment of mobile phone parts, in particular to a hanging structure for surface treatment of a mobile phone middle plate. Background Art

[0002] During the processing of mobile phone parts such as mobile phone shells, in order to enhance the wear resistance and scratch resistance of the mobile phone shells, the mobile phone shells are usually hung and then sprayed on their surfaces to ensure the uniformity and quality of the surface treatment.

[0003] After searching, the Chinese patent "An automatic spraying device for spraying mobile phone shells" with authorization announcement number "CN218574003U" realizes vacuum adsorption of mobile phone shells through a nozzle adsorption plate, motor, rotor, sealing block and air intake one-way valve, ensuring the stability of spraying the mobile phone shell while moving.

[0004] Since the mobile phone shell needs to be sprayed in the entirety during the spraying process, the mobile phone shell is vacuum-adsorbed by the adsorption plate, which causes dead corners in the mobile phone shell during the spraying process, thereby affecting the spraying effect of the mobile phone shell.

[0005] Therefore, a hanging structure for surface treatment of a mobile phone mid-plate is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] When implementing: Figure 1-4As shown, a hanging structure for surface treatment of a mobile phone mid-plate comprises: a spray box 1, the front end of the spray box 1 is hinged with two transparent windows 2, the inner bottom of the spray box 1 is fixedly connected to a servo motor 3, both sides of the interior of the spray box 1 are rotatably connected to pulleys 4, a conveyor belt 5 is connected between the surfaces of the two pulleys 4, and the output shaft of the servo motor 3 is fixedly connected to the bottom end of one of the pulleys 4; a hanging mechanism 6, the hanging mechanism 6 is arranged inside the spray box 1; wherein the hanging mechanism 6 includes hanging frames 61 fixedly connected to the surface of the conveyor belt 5 and distributed in rows, and the inner bottom of the spray box 1 is fixedly connected to the conveyor belt 5. The top of the spray box 1 is fixedly connected to a fixing rod 62, and the upper end of the surface of the fixing rod 62 is fixedly connected to two toggle rods 69. The top of the hanging frame 61 is clamped with a limiting frame 65, and the lower end of the surface of the limiting frame 65 is funnel-shaped. The inner top of the spray box 1 is fixedly connected to two limiting rods 66, and the surface of the limiting rod 66 is slidably connected to the limiting plate 63. A limiting groove 64 is provided inside the limiting plate 63. The upper end of the surface of the limiting frame 65 is slidably connected to the inside of the limiting groove 64, and the inside of the limiting plate 63 is slidably connected to a positioning rod 67, and the surface of the positioning rod 67 is clamped to the inner wall of the limiting rod 66.

[0025] The transparent window 2 is slidably connected to a pin rod inside, and the lower end of the pin rod is clamped on the top of the spray box 1. A material box is provided inside the spray box 1, and the top of the material box is connected to a spray pump. The upper end of the interior of the spray box 1 is fixedly connected to a nozzle, and the liquid outlet end of the spray pump passes through the spray box 1 and is connected to the inner wall of the nozzle.

[0026] When the surface of the mobile phone shell needs to be sprayed, the transparent window 2 is opened, the mobile phone shells are hung on the hanging frame 61 one by one, and one of the positioning rods 67 is pulled down. The positioning rod 67 moves down to drive the limit plate 63 to move down, so that multiple limit frames 65 move down at the same time and are connected to the corresponding hanging frame 61, and the positioning rod 67 is pushed so that the positioning rod 67 moves in the limit plate 63 and is connected to the limit rod 66, and the transparent window 2 is pushed to close the front end of the spray box 1 and position the transparent window 2 in the spray box 1, and the servo motor 3 and the spray pump are manually turned on. The output shaft of the servo motor 3 rotates to drive one of the pulleys 4, and the rotation of one of the pulleys 4 drives the conveyor belt 5, which drives the hanging frame 61 to move. The movement of the hanging frame 61 drives the mobile phone housing and the limit frame 65 to move, so that the limit frame 65 moves in the limit groove 64. The spray pump draws the liquid in the material box and sprays the moving mobile phone housing through the spray head. One of the mobile phone housings moves to the toggle rod 69, so that the mobile phone housing is rotated on the hanging frame 61, so that the spray head sprays the dead corner of the mobile phone housing blocked by the hanging frame 61. After spraying is completed, the servo motor 3 and the spray pump are manually turned off, and then the front end of the spray box 1 is opened to take out the sprayed mobile phone housing.

[0027] like Figure 3-4As shown, the rear end of the transparent window 2 is fixedly connected to a stopper 611, the rear end of which contacts the front end of the positioning rod 67. The upper surface end of the positioning rod 67 is fixedly connected to a connecting rod 68. The surface of the positioning rod 67 is fixedly connected to a slip ring 610. The surface of the slip ring 610 is slidably connected to the inner wall of the limit plate 63. The upper surface end of the limit frame 65 is fixedly connected to a ball bearing 612. The surface of the ball bearing 612 is fixedly connected to the inner wall of the limit groove 64. The overall positioning rod 67 is in an "L" shape. The ball bearing 612 allows the limit frame 65 to move smoothly within the limit groove 64. The slip ring 610 prevents the positioning rod 67 from disengaging from the limit plate 63 during lateral movement within the limit plate 63, thereby avoiding the inconvenience of re-inserting the positioning rod 67 into the limit plate 63 later.

[0028] When the utility model is in use, the transparent window 2 is opened, the mobile phone shells are hung on the hanging frame 61 one by one, one of the positioning rods 67 is pulled down, the positioning rod 67 moves down to drive the limit plate 63 to move down, so that multiple limit frames 65 move down at the same time and are connected to the corresponding hanging frame 61, the positioning rod 67 is pushed, so that the positioning rod 67 moves in the limit plate 63 and is connected to the limit rod 66, and the transparent window 2 is pushed to close the front end of the spray box 1 and position the transparent window 2 in the spray box 1, so that the rear end of the block 611 contacts the front end of the positioning rod 67, and the servo motor is manually started. 3 and the spray pump, the output shaft of the servo motor 3 rotates to drive one of the pulleys 4 to rotate, and the rotation of one of the pulleys 4 drives the conveyor belt 5 to drive, and the conveyor belt 5 drives the hanging frame 61 to move, and the hanging frame 61 moves to drive the mobile phone shell and the limit frame 65 to move, so that the limit frame 65 moves in the limit groove 64, and the spray pump extracts the material liquid in the material box and sprays the moving mobile phone shell through the nozzle. One of the mobile phone shells moves to the toggle rod 69, so that the mobile phone shell is rotated on the hanging frame 61, so that the nozzle sprays the dead corner of the mobile phone shell blocked by the hanging frame 61.

[0029] It should be noted that the spray pump, nozzle, spray box 1, transparent window 2, servo motor 3, pulley 4, conveyor belt 5, etc. in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the spray pump and servo motor 3 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
