Description

Technical Field

[0001] The invention relates to the technical field of laser marking, in particular to a mobile phone shell laser marking device. Background Art

[0002] With the booming development of today's mobile phone manufacturing industry, the personalized design and refined production of mobile phone shells have become key factors in improving product competitiveness. Laser marking technology, with its advantages of high precision and permanence, is widely used in the production of brand logos and decorative patterns on mobile phone shells. However, with the increasing diversification of mobile phone appearance designs, mobile phone shells have shown significant differences in size and shape. There is no unified standard for the size and shape of mobile phone shells of different models, which brings severe challenges to laser marking processing.

[0003] At present, most mobile phone case laser marking equipment still relies on manual adjustment of fixture positioning when dealing with differences in case shapes. Operators need to adjust the position, angle and tightness of the fixture one by one according to the specific appearance of the mobile phone case to ensure the stability and accuracy of the case during the marking process. This method is not only cumbersome and time-consuming, but also seriously reduces production efficiency and cannot meet the needs of large-scale and batch production.

[0004] In addition, in the loading and unloading process, the existing equipment also requires a lot of manual intervention. When loading manually, the mobile phone shells need to be accurately placed on the fixture one by one. When unloading, the marked shells need to be removed in time and transported to the next process, which consumes a lot of manpower costs. At the same time, the speed of manual loading and unloading is much lower than the processing speed of the equipment, which makes the equipment idle while waiting for loading and unloading, further reducing the overall production efficiency and restricting the company's production capacity improvement and economic benefit growth. Therefore, a mobile phone shell laser marking equipment is proposed to solve the above problems. Summary of the Invention

[0035] In this embodiment, the mounting portion 2 includes a slide 21, which is mounted on the table of the laser marking machine body 1. The inner wall of the slide 21 is slidably connected to a rod sleeve 22. A support arm 23 is mounted on the side wall of the laser marking machine body 1. A rod sleeve 2 is fixedly connected to the support arm 23. A workbench 24 is mounted on the laser marking machine body 1. A marking table 25 is mounted on the table of the laser marking machine body 1. The table of the workbench 24 is on the same horizontal line as the table of the marking table 25. Slides 26 are symmetrically mounted on both sides of the marking table 25. The slides 26 are used to guide the positioning plate 32 to move in a straight line. In order to facilitate entry into the marking table 25 and guide the mobile phone case 8 into the discharge channel 9, the positioning part 3 also includes an electric push rod 2 35, the inner rod end of the electric push rod 2 35 is fixedly connected to the positioning plate 2 36, and one side of the positioning plate 2 36 is fixedly connected to a sliding arm 37, and the sliding arm 37 is slidably connected to the inner wall of the sliding hole 33, the outer rod of the electric push rod 2 35 is fixedly connected to the inner wall of the rod sleeve 1 22, and the outer rod of the electric push rod 1 31 is fixedly connected to the inner wall of the rod sleeve 2, the bottoms of the positioning plate 1 32 and the positioning plate 2 36 are both in contact with the surface of the marking table 25, and the electromagnet 42 and the adsorption block 49 are attracted to each other by opposite poles.

[0036] It is worth noting that an adjustment part 5 is provided on the workbench 24 for freely adjusting the loading position of the mobile phone case 8. The adjustment part 5 includes a support plate 51, on which a second slide 52 is installed. The inner wall of the second slide 52 is rotatably connected to a screw 53, and a handwheel 54 is installed at the end of the screw 53. The inner wall of the second slide 52 is slidably connected to a rod sleeve 3 55, and the rod sleeve 3 55 is threadedly sleeved on the screw 53.

[0037] A loading part 6 is provided on the rod sleeve three 55, which is used to push the mobile phone cases 8 into the laser area one by one. The loading part 6 includes an electric push rod three 61, and the inner rod end of the electric push rod three 61 is fixedly connected to a loading plate 62. The loading plate 62 is an L-shaped structure, and one end of the loading plate 62 is fixedly connected to a limited distance arm 63. A sensor two 64 is installed on the loading plate 62, and the support plate 51 is installed on the workbench 24. The outer rod of the electric push rod three 61 is fixedly connected to the inner wall of the rod sleeve three 55, and the outer wall of the loading plate 62 is fixedly connected to a supporting plate. The top of the supporting plate is on the same horizontal line as the top of the loading plate 62. The electric push rod one 31, the electric push rod two 35 and the electric push rod three 61 are all electrically connected to the control panel of the laser marking machine body 1, and the bottom of the loading plate 62 is connected to the workbench 24. The table top fits together, the bottom of the distance limiting arm 63 is higher than the top of the positioning plate 2 36, the sensor 2 64 is electrically connected to the control panel of the laser marking machine body 1, and the sensor 1 34 and the sensor 2 64 are both distance sensors. When the loading plate 62 pushes the mobile phone case 8 into the marking table 25, the mobile phone case 8 is fixed at the angle between the positioning plate 1 32 and the positioning plate 2 36 away from the diagonal of the loading plate 62. The center of the mobile phone case 8 is located at the center of the marking table 25 and at the coordinate origin. The distance limiting arm 63 blocks the infrared rays of the sensor 1 34 to generate an electrical signal, thereby activating the electromagnet 42 through the control panel to absorb the adsorption block 49. After the sensor 2 64 detects a distance equal to the mobile phone case 8, it stops the electric push rod 3 61 through an electrical signal to complete the loading and fixing.

[0038] It is worth noting that a storage portion 7 is also provided on the rod sleeve three 55 for pre-storing and stacking a number of mobile phone cases 8. The electric push rod three 61 is telescopically moved to release the mobile phone case 8 at the bottom of the stack and drop it onto the workbench 24. When the loading plate 62 pushes the mobile phone case 8 into the laser area, the support plate blocks other mobile phone cases 8 from falling downward, in preparation for the next loading. The storage portion 7 includes a mounting arm 71. One end of the mounting arm 71 is fixedly connected to the rod sleeve three 55. The other end of the mounting arm 71 is fixedly connected to a limiting plate 72. The limiting plate 72 is an L-shaped structure and its bottom is fitted with the top of the support plate. An adjusting slot 73 is provided at one end of the limiting plate 72. An adjusting plate 74 is slidably connected to the adjusting slot 73. The upper part is fixedly connected with an adjusting rod 75, which slides through the limit plate 72. The other end of the limit plate 72 is provided with an adjusting slot 2 76. The inner wall of the adjusting slot 2 76 is slidably connected with an adjusting plate 2 77. The adjusting plate 2 77 is fixedly connected with an adjusting rod 2 78, which slides through the limit plate 72. The adjusting plate 1 74 and the adjusting plate 2 77 are both L-shaped structures. A mobile phone case 8 is stacked between the adjusting plate 1 74, the limit plate 72 and the adjusting plate 2 77. The sliding adjusting rod 1 75 and the adjusting rod 2 78 can preset the storage area of ​​the mobile phone case 8 corresponding to the size, thereby facilitating stacking and feeding. The table top of the laser marking machine body 1 is provided with a discharge channel 9, which is inclined and connected to the side wall of the laser marking machine body 1.

[0039] Working principle: the table top of the marking table 25 constructs a two-dimensional plane coordinate system, and the positioning plate 1 32 and the positioning plate 2 36 are moved and adjusted to adapt to mobile phone cases 8 of different sizes, while ensuring that the origin of the laser area is located at the center point of the marking table 25, so as to facilitate the positioning of the coordinate position of the mobile phone case 8 when loading, and further ensure that each mobile phone case 8 is at the origin position during the marking process. By sliding the adjusting rod 1 75 and the adjusting rod 2 78, the distance between the adjusting plate 1 74 and the adjusting plate 2 77 is changed to adapt to the stacking space of mobile phone cases 8 of different sizes. The mobile phone case 8 is stacked between the limit plate 72, the adjusting plate 1 74 and the adjusting plate 2 77, and the bottom is fitted with the support plate.

[0040] When the electric push rod three 61 is extended, the L-shaped loading plate 62 moves along the workbench 24 to the marking table 25. The support plate of the loading plate 62 blocks the mobile phone case 8 above and only pushes the mobile phone case 8 on the bottom layer forward. When the mobile phone case 8 is pushed to the marking table 25, the distance limiting arm 63 blocks the infrared ray of the sensor one 34. The sensor one 34 sends an electrical signal to the control panel, activating the electromagnet 42 to attract the adsorption block 49. At the same time, the sensor two 64 detects the distance of the mobile phone case 8. In actual application, this distance should be equal to the length of the mobile phone case 8, so that the feedback signal stops the electric push rod three 61 and completes the loading positioning.

[0041] According to the actual size of the mobile phone case 8, the coordinate positions to which the positioning plate 1 32 and the positioning plate 2 36 should be moved are determined. The center point of the positioning plate 1 32 should be at 1 / 2 the length of the mobile phone case 8, and the positioning plate 2 36 should be at 1 / 2 the width of the mobile phone case 8. The electric push rod 1 31 is started first and makes the positioning plate 1 32 stay at the corresponding coordinate. After the electric push rod 2 35 reaches the position of the positioning plate 1 32, it drives the positioning plate 2 36 to move. At the same time, the sliding arm 37 slides in the sliding hole 33 of the positioning plate 1 32 to form an adaptive adjustment of the angle, thereby determining the laser area.

[0042] After the mobile phone case 8 enters the laser area, its diagonal contact is made with the included angle of the positioning plate 1 32 and the positioning plate 2 36, and the bottom of the two is in contact with the marking platform 25, so as to realize precise horizontal limit and ensure that the center of the mobile phone case 8 is aligned with the center of the marking platform 25. After the positioning of the mobile phone case 8 is completed, the control panel starts the laser marking machine body 1 to perform laser marking on the surface of the mobile phone case 8. After the marking is completed, the electric push rod 3 61 contracts, and the distance detection signal of the sensor 1 34 is disconnected. The control panel controls the electromagnet 42 to cut off the power, release the adsorption block 49, and the spring 48 resets and pushes the push block 47, which pops out from the groove 43 and hits the mobile phone case 8, so that it slides into the inclined discharge channel 9 along the marking platform 25 and falls to the outside of the equipment for recovery.

[0043] The handwheel 54 of the adjustment part 5 drives the screw 53 to rotate, driving the rod sleeve three 55 to move in the slide groove two 52, thereby adjusting the lateral position of the feeding part 6 and the storage part 7, adapting to the initial position of the laser area feeding under different sizes of mobile phone cases 8, and ensuring the precise connection of each action.
