Description

Technical Field

[0001] This utility model relates to the field of electronic product processing technology, specifically to an electronic product processing and polishing device. Background Technology

[0002] Electronic products are products that use electricity as their working basis. They mainly include: watches, smartphones, telephones, televisions, DVD players, radios, stereo systems, computers, mobile communication products, etc. Because early products mainly used vacuum tubes as their basic components, they are called electronic products. During the manufacturing process of electronic products, their surfaces need to be polished.

[0003] In existing electronic product processing and polishing equipment, the polishing wheel, as the core component, contacts the workpiece surface through high-speed rotation to achieve polishing. However, over long-term use, the abrasive particles (such as sand grains and fibers) on its surface will gradually fall off or become dull due to friction. The worn polishing wheel can no longer provide sufficient cutting force, and defects such as scratches and orange peel texture may remain on the workpiece surface. It needs to be replaced in time to ensure the quality of processing. Usually, the polishing wheel is fixed to the drive mechanism with multiple bolts. When replacing it, tools are needed to remove the bolts one by one, replace the new polishing wheel, and then tighten the bolts one by one. The operation steps are cumbersome and time-consuming, which prolongs the downtime of the equipment and reduces the convenience of maintenance. Utility Model Content

[0004] The purpose of this invention is to provide an electronic product processing and polishing device to solve the problems mentioned in the background art.

[0020] 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.

[0021] Please see Figure 1-4As shown, an electronic product processing and polishing device includes a worktable 1. A drive assembly 2 and a dust collection assembly 4 are mounted on the top of the worktable 1. The drive assembly 2 consists of a motor, a threaded rod, and a sliding rod. A lifting mechanism, common in the prior art for adjusting height, can be installed on the drive assembly 2 to adjust the position of a moving plate 3 to complete the polishing process of the electronic product. The dust collection assembly 4 consists of a centrifugal fan, a dust hood, a filter, and a processing box, used to collect dust generated during polishing; this is prior art and will not be elaborated further. A moving plate 3 is mounted on the outer side of the drive assembly 2. A motor 5 is fixedly connected to the top of the moving plate 3 and powered by an external power source. A transmission rod 6 is mounted at the output end of the motor 5 to transmit the kinetic energy output by the motor 5. A polishing wheel 7 is mounted at one end of the transmission rod 6. The motor 5 drives the polishing wheel 7 to rotate at high speed through the transmission rod 6, bringing it into contact with the surface of the electronic product to remove burrs, scratches, protrusions, and other unevenness. The polishing wheel 7 is part of a larger component to make the surface smoother for polishing. It also includes a connecting mechanism 8 for quick assembly and disassembly of the polishing wheel 7, located on the outside of the transmission rod 6. The connecting mechanism 8 includes a housing 81, a spring 82, a positioning component 85, a screw 86, and a threaded groove 87. The housing 81 is fixed to the outside of the transmission rod 6, the spring 82 is sleeved on the outside of the transmission rod 6, the positioning component 85 is located on the top of the polishing wheel 7, the screw 86 is fixed to the bottom of the housing 81, and the top of the polishing wheel 7 has a threaded groove 87. The outside of the screw 86 is threadedly connected to the inner wall of the threaded groove 87. The two components can be connected or separated by rotating the polishing wheel 7. The connecting mechanism 8 also includes a transmission component 83, a guide component 84, an adjustment component 88, and a fixing component 89. The transmission component 83 is located at the bottom end of the spring 82, the guide component 84 is located on the inner wall of the housing 81, the adjustment component 88 is located inside the transmission component 83, and the fixing component 89 is located outside the housing 81.

[0022] The transmission assembly 83 includes a transmission frame 831 that slides on the outside of the transmission rod 6. Four fixing blocks 832 are fixedly connected to the outside of the transmission frame 831. One end of a spring 82 is fixed to the top of the transmission frame 831. After the transmission frame 831 moves upward, the spring 82 will push the transmission frame 831 downward to reset through the accumulated elastic force. The guide assembly 84 includes a sliding block 841 fixed to the outside of the fixing blocks 832. A guide groove 842 is formed on the inner wall of the outer casing 81. The outer side of the sliding block 841 is aligned with the guide groove 842. The inner sliding connection allows the sliding block 841 to move synchronously with the transmission frame 831 and slide along the inner side of the guide groove 842, thereby restricting the movement path of the transmission frame 831 and causing the positioning block 851 to engage in the limiting groove 852 according to a predetermined route. The positioning assembly 85 includes a positioning block 851 fixed to the bottom of the fixing block 832. The top of the polishing wheel 7 has a limiting groove 852. The outer side of the positioning block 851 engages with the inner side of the limiting groove 852, allowing the positioning block 851 to enter the inner side of the limiting groove 852. Afterwards, the polishing wheel 7 will be fixed to the bottom of the housing 81 and cannot rotate; the adjusting assembly 88 includes a rotating ring 881 that rotates inside the transmission frame 831, and an adjusting rod 882 is fixedly connected to the outer side of the rotating ring 881. A vertical groove 883 is opened on the inner wall of the housing 81, and one end of the vertical groove 883 is connected to a horizontal groove 884. When the adjusting rod 882 is pushed to the end of the vertical groove 883, the adjusting rod 882 is turned to rotate inside the horizontal groove 884, which will limit the adjusting rod 882 and prevent the spring 82 from rotating. The transmission frame 831 is moved and reset; the fixing component 89 includes a connecting seat 891 fixed to one side of the housing 81. The inner side of the connecting seat 891 is rotatably connected to a limit block 892. The limit block 892 is designed to have a large damping when rotating along the connecting seat 891. When the positioning block 851 enters the inner side of the limit groove 852, the adjusting rod 882 is located at the bottom end of the vertical groove 883. Rotating the limit block 892 so that it is located above the adjusting rod 882 can prevent the adjusting rod 882 from moving and maintain its stability.

[0023] Working principle: When the polishing wheel 7 needs to be replaced during use, the adjusting rod 882 first slides upward along the vertical groove 883, causing the transmission frame 831 to compress the spring 82. As the transmission frame 831 moves, it separates the positioning block 851 from the inner side of the limiting groove 852 via the fixing block 832. After the adjusting rod 882 reaches the top of the vertical groove 883, it is then turned to make the rotating ring 881 rotate along the inner side of the transmission frame 831. The adjusting rod 882 can then be inserted into the horizontal groove 884, limiting its movement. At the same time, the transmission frame 831 cannot move. Then, the polishing wheel 7 is rotated to move along the spiral groove 884. Rotate the rod 86 along its axis, then separate the screw 86 from the threaded groove 87, completing the disassembly of the polishing wheel 7. Next, pick up the polishing wheel 7 to be replaced, align the threaded groove 87 on its top with the screw 86, and tighten it by rotation to complete the docking with the screw 86. Then rotate the adjusting rod 882 to disengage it from the inside of the transverse groove 884. After the adjusting rod 882 loses its limit, the elastic force of the spring 82 is released, pushing the transmission frame 831 to move towards the limiting groove 852, and with the positioning block 851, it is inserted into the inside of the limiting groove 852. At this time, the polishing wheel 7 cannot rotate laterally, thus forming a fixed connection between the polishing wheel 7 and the transmission rod 6, completing the replacement.
