Description

Technical Field

[0001] This utility model relates to the field of mobile phone parts processing technology, and in particular to a sandblasting device for mobile phone buttons. Background Technology

[0002] Mobile phone button sandblasting equipment is a device specifically designed for sandblasting the surface of mobile phone buttons. Its main function is to remove burrs and oxide layers from the button surface, or to roughen the surface, thereby improving the appearance quality and subsequent processing performance of the buttons. However, most existing sandblasting devices adopt a handheld sandblasting method. Due to the small size of mobile phone buttons, handheld sandblasting is not only inconvenient to operate, but also difficult to accurately control the sandblasting angle and force, which can easily lead to uneven sandblasting results and may even damage the button surface. Although mechanical sandblasting can improve the degree of automation, most current equipment still uses fixed-angle sandblasting. This single sandblasting angle is difficult to adapt to the complex shape and varied surface requirements of buttons, which can easily lead to differences in surface roughness in different parts, thus affecting the overall sandblasting effect and quality uniformity.

[0003] Therefore, this utility model proposes a sandblasting device for mobile phone buttons. Utility Model Content

[0004] The purpose of this invention is to provide a sandblasting device for mobile phone buttons to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sandblasting device for mobile phone buttons includes a base plate, the base plate having a plurality of sliding grooves arranged in a linear array, and two sets of fixing mechanisms slidably connected inside the sliding grooves.

[0007] A column is fixedly connected to the side of the base plate, a motor is fixedly connected to the top of the column, a drive shaft is fixedly connected to the output end of the motor, the outer wall of the drive shaft is movably sleeved with the column, and a sandblasting mechanism is fixedly connected to the bottom end of the drive shaft.

[0008] Furthermore, the sandblasting mechanism includes a transmission rod, one top end of which is fixedly connected to a transmission shaft, and the other bottom end of which is fixedly connected to a hinge block one. The bottom end of the hinge block one is fixedly connected to a sandblasting head. A groove is provided on the outer wall of the sandblasting head, and a hinge block two is slidably sleeved inside the groove. An adjusting rod is hinged to the top end of the hinge block two, and the outer wall of the adjusting rod is movably sleeved with the transmission rod.

[0009] Furthermore, one side of the outer wall of the adjusting rod is serrated, the side of the adjusting rod engages with the limiting block, one end of a spring is fixedly connected to the side of the limiting block, the other end of the spring is fixedly connected to the inner wall of the transmission rod, and a lever is fixedly connected to the top of the limiting block, the outer wall of the lever is slidably sleeved with the transmission rod.

[0010] Furthermore, the fixing mechanism includes a connecting rack, the outer wall of which is meshed with five sets of gears arranged in a linear array, and each of the five sets of gears is movably fitted with a limiting shaft. The outer wall of each gear is meshed with two sets of fixing racks arranged in a circular array with the limiting shaft as the center. A connecting rod is fixedly fitted inside the fixing rack, and a soft support block is fixedly fitted at the top of the connecting rod.

[0011] Furthermore, one end of the second spring is fixedly connected to the side of the fixed rack, and the other end of the second spring is fixedly connected to a baffle. The upper and lower ends of the baffle are fixedly connected to the base plate.

[0012] Furthermore, the outer wall of the connecting rod is slidably sleeved with the base plate, and the top end of the base plate is in contact with the bottom end of the soft support block.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By starting the motor, the drive shaft rotates inside the column, causing the sandblasting device at the bottom to rotate around the drive shaft for sandblasting. By adjusting the height of the adjusting rod inside the drive shaft, the angle of the sandblasting head can be adjusted, thereby improving the product's adaptability to buttons of different sizes. The rotary sandblasting, through continuous spraying without dead angles, ensures a uniform sandblasting effect on the surface of the mobile phone buttons, effectively avoiding the problem of insufficient or excessive sandblasting in certain areas caused by sandblasting at a fixed angle. It is especially suitable for small buttons with complex shapes.

[0015] 2. By pushing the connecting rack, the gear rotates around the limiting shaft, causing the fixed rack to mesh with the gear and rotate. The fixed rack further drives the soft support block to move inward, facilitating the placement of the receiving button. The thrust on the connecting rack is removed, and the fixed rack returns to its original position due to the elastic potential energy of the spring, thus fixing the phone button. After fixing the phone button, sandblasting is performed. This ensures that the position and angle of the button remain unchanged during the sandblasting process, allowing the sandblasting medium to act evenly on the button surface and avoiding uneven sandblasting or local omissions caused by button movement.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 6 As shown, the sandblasting device for mobile phone buttons provided by this utility model includes a base plate 1. The base plate 1 has several sets of sliding grooves inside, and the several sets of sliding grooves are arranged in a linear array. Two sets of fixing mechanisms are slidably sleeved inside the sliding grooves.

[0027] A column 2 is fixedly connected to the side of the base plate 1, a motor 3 is fixedly connected to the top of the column 2, a drive shaft 4 is fixedly connected to the output end of the motor 3, the outer wall of the drive shaft 4 is movably sleeved with the column 2, and a sandblasting mechanism is fixedly connected to the bottom end of the drive shaft 4.

[0028] The sandblasting mechanism includes a transmission rod 5. The top end of one side of the transmission rod 5 is fixedly connected to the transmission shaft 4, and the bottom end of the other side of the transmission rod 5 is fixedly connected to a hinge block 7. The bottom end of the hinge block 7 is fixedly connected to the sandblasting head 8. The outer wall of the sandblasting head 8 is provided with a sliding groove. The inner side of the sliding groove is fitted with a hinge block 9. The top end of the hinge block 9 is hinged to an adjusting rod 6. The outer wall of the adjusting rod 6 is movably fitted with the transmission rod 5.

[0029] One side of the outer wall of the adjusting rod 6 is serrated. The side of the adjusting rod 6 engages with the limiting block 12. One end of the spring 13 is fixedly connected to the side of the limiting block 12. The other end of the spring 13 is fixedly connected to the inner wall of the transmission rod 5. The top of the limiting block 12 is fixedly connected to the lever 11. The outer wall of the lever 11 is slidably sleeved with the transmission rod 5.

[0030] During sandblasting, motor 3 is started first. The output end of motor 3 drives the transmission shaft 4 to rotate inside the column 2, which in turn drives the sandblasting mechanism at the bottom to rotate synchronously around the transmission shaft 4 as the center, performing rotational sandblasting on the mobile phone button fixed at the bottom, so that the mobile phone button is sandblasted evenly. When it is necessary to sandblast mobile phone buttons of different sizes, the required sandblasting range needs to be adjusted. At this time, the adjusting rod 6 is pulled upward. At this time, the sawtooth-shaped beveled surface of the adjusting rod 6 rubs against the beveled surface of the limiting block 12, further driving the limiting block 12 to move to the other side, thereby raising the height of the adjusting rod 6. When the adjusting rod 6 is fully raised... After completion, the spring 13, under the influence of its elastic potential energy, pushes the limiting block 12 to re-engage with the adjusting rod 6, thereby limiting the height of the adjusting rod 6. Conversely, when the adjusting rod 6 needs to be adjusted downwards, the pull block 11 is pulled to slide to the other side of the transmission rod 5. The bottom end of the pull block 11 drives the limiting block 12 to slide inside the transmission rod 5. At this time, the height of the adjusting rod 6 inside the transmission rod 5 can be adjusted. When the height of the adjusting rod 6 is adjusted, the hinge block 2 9, which is hinged at the bottom end of the adjusting rod 6, pulls one end of the sandblasting head 8 to raise it, and drives the hinge block 1 7 to rotate, adapting to different lifting angles of the sandblasting head 8.

[0031] Example 2

[0032] Based on Example 1, please refer to Figures 4 to 6 As shown, the fixing mechanism includes a connecting rack 20, with five sets of gears 18 meshing on the outer wall of the connecting rack 20, and the five sets of gears 18 are arranged in a linear array. Each of the five sets of gears 18 is movably sleeved with a limiting shaft 19. Two sets of fixing racks 14 mesh on the outer wall of the gears 18, and the two sets of fixing racks 14 are arranged in a circular array with the limiting shaft 19 as the center. A connecting rod 15 is fixedly sleeved inside the fixing rack 14, and a soft support block 10 is fixedly sleeved at the top of the connecting rod 15.

[0033] One end of a second spring 16 is fixedly connected to the side of the fixed rack 14, and the other end of the second spring 16 is fixedly connected to a baffle 17. The upper and lower ends of the baffle 17 are fixedly connected to the base plate 1.

[0034] The outer wall of the connecting rod 15 is slidably sleeved with the base plate 1, and the top of the base plate 1 is in contact with the bottom of the soft support block 10.

[0035] When it is necessary to fix the mobile phone button, first push the connecting rack 20 to move it inward into the base plate 1. When the connecting rack 20 moves, it meshes with multiple sets of gears 18 on the side, causing the gears 18 to rotate around the limiting shaft 19. This further causes the fixed racks 14 on both sides of the gears 18 to mesh and rotate with them. The two sets of fixed racks 14 move inward, and then the connecting rod 15 drives the soft support block 10 to move to the opposite side. Then, each mobile phone button that needs to be sandblasted is aligned with two sets of soft support blocks 10 at the top of the base plate 1. After placement, the pushing force on the connecting rack 20 is released. Under the influence of the elastic potential energy of multiple sets of springs 16, the fixed rack 14 is pushed back into place. Then, the meshing of the fixed rack 14 with the gears 18 drives the connecting rack 20 at the bottom to reset. At the same time as the fixed rack 14 resets, the connecting rod 15 drives the soft support block 10 at the top to fix the mobile phone button, so that the mobile phone button is fixed to the surface of the base plate 1, which facilitates the subsequent sandblasting work.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
