Description

Technical Field

[0001] This utility model relates to the field of mobile phone case processing technology, and in particular to a deburring and polishing device for mobile phone cases. Background Technology

[0002] With the rapid development and widespread use of mobile phones, there are many types of mobile phone cases. Currently, most mobile phone cases are made of plastic and metal. Mobile phone cases are usually made by injection molding. During the injection molding process, after the two mold parts separate, mold lines will be left on both sides of the mobile phone case.

[0003] Parting lines are typically thin, elongated protrusions or depressions that disrupt the integrity of the phone case surface, especially noticeable with glossy or high-gloss coating processes. For minimalist designs or high-end products, parting lines reduce the "seamless, seamless" feel, affecting the user's perception of quality. Currently, most solutions remove parting lines by water jetting. This involves pressurizing water with an ultra-high-pressure pump and creating a high-speed jet through a precision nozzle. The high-pressure water jet impacts the burrs at the parting line, using water kinetic energy to shear and peel off excess material while avoiding damage to the phone case itself. For hard materials, micron-level abrasives can be added to create an abrasive water jet, enhancing cutting efficiency.

[0004] Existing waterjet equipment mainly consists of a clamping component and a spraying component. The clamping component's primary function is to secure the phone case, while the spraying component removes the parting line from the phone case surface using high-pressure water jets. However, this traditional clamping component has a limited function, only able to secure the phone case and unable to automatically flip it over after removing the parting line. Therefore, after removing the parting line on one side of the phone case, it needs to be manually flipped over to process the other side. This manual flipping operation is not only time-consuming and labor-intensive, reducing production efficiency, but also increases the risk of injury as operators may come into contact with high-pressure water jets or other dangerous parts during the flipping process. Furthermore, frequent manual intervention can lead to equipment instability, further affecting processing quality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deburring and polishing device for mobile phone cases.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a deburring and polishing device for mobile phone cases, comprising a processing table, with a multi-axis adjusting seat and a clamping table respectively provided at both ends of the top of the processing table. A water jet nozzle is fixed on the bottom surface of the multi-axis adjusting seat. A rotating seat is rotatably connected to the inner wall of the clamping table. A clamping seat is detachably connected to one side of the rotating seat. A lead screw is bearing-connected to the side wall of the clamping seat. Both ends of the lead screw are threadedly connected to clamping suction cups, and the clamping suction cups are slidably connected to the inner wall of the clamping seat. The lead screw is driven by a motor. A worm gear is fixed on the other side of the rotating seat. A worm is meshed on the surface of the worm gear, and both ends of the worm are bearing-connected to bearing seats. The worm is driven by a worm rotation motor. Both the bearing seats and the worm rotation motor are fixed to the surface of the clamping table.

[0007] Preferably, the rotating base has a slot on its side, and each slot has a limiting groove on its sidewall. A slider is slidably connected inside the limiting groove, and a limiting roller is provided on the side of the slider. A limiting spring is fixed between the slider and the sidewall of the limiting groove. A plug is fixed on the side of the clamping base, and a semi-circular locking groove is provided on the surface of the plug. Since the clamping base needs to continuously clamp the phone case, it needs to be inspected regularly after long-term operation to avoid affecting the processing of the phone case. To address this problem, this utility model adopts a detachable structure. During installation, the plug on the side of the clamping base is inserted into the slot on the side of the rotating base. The plug squeezes the limiting roller until the plug is fully inserted into the slot. Under the action of the limiting spring, the limiting roller engages with the semi-circular locking groove on the surface of the plug, improving the tightness of the clamping base and the rotating base. During disassembly, the clamping base can be pulled out by force. It is easy to disassemble and assemble, simple to operate, and convenient to inspect the clamping mechanism.

[0008] Preferably, rubber sleeves are bonded to the inner wall of the semicircular locking groove and the surface of the limiting roller. The rubber sleeves not only increase the friction between the semicircular locking groove and the limiting roller, further improving the stability between the turntable and the clamping seat, but also play a protective role, reducing the wear of the limiting roller.

[0009] Preferably, both sides of the limiting roller are fixedly connected to the slider to prevent the limiting roller from sliding or rolling relative to each other, thereby improving the stability between the turntable and the clamping seat.

[0010] Preferably, the helix angle of the worm is less than the equivalent friction angle between the meshing teeth of the worm and the worm wheel. When the helix angle of the worm is less than the equivalent friction angle between the meshing teeth of the worm and the worm wheel, the worm wheel and worm structure has self-locking property, that is, the worm can drive the worm wheel to rotate, but the worm wheel cannot drive the worm to rotate, which improves the stability of the rotating seat and prevents the impact force of the water jet from causing the rotating seat to shake.

[0011] Preferably, the inner wall of the slot is arrayed with a second limiting groove, and a limiting protrusion is slidably connected inside the second limiting groove. A compression spring is fixed between one side of the limiting protrusion and the side wall of the second limiting groove. When the clamping seat is connected to the rotating seat, the limiting protrusion is further squeezed by the plug, and finally the plug is tightly locked under the action of the compression spring, which further improves the tightness between the plug and the slot.

[0012] Preferably, the other side of the limiting protrusion is hemispherical to facilitate the insertion of the plug into the slot.

[0013] Beneficial effects

[0014] Existing waterjet equipment mainly consists of a clamping assembly and a spraying assembly. The clamping assembly's primary function is to secure the phone case, while the spraying assembly removes the parting line from the phone case surface using high-pressure water jets. However, this traditional clamping assembly has a limited function, only securing the phone case and unable to automatically flip it over after removing the parting line. Therefore, after removing the parting line on one side of the phone case, it needs to be manually flipped over to process the other side. This manual flipping operation is not only time-consuming and labor-intensive, reducing production efficiency, but also increases the risk of injury as operators may come into contact with high-pressure water jets or other dangerous parts during the flipping process. Furthermore, frequent manual intervention... Pre-emptive measures may lead to unstable equipment operation, further affecting processing quality. To address this issue, this invention employs an automatic clamping and rotating mechanism. The phone case is clamped using a clamping suction cup. A motor drives a lead screw to rotate, which in turn moves the clamping suction cups in opposite directions, thus clamping the phone case. A water jet nozzle is then activated to remove the parting line. A multi-axis adjusting seat adjusts the nozzle's direction on the x, y, and z axes. Once the parting line on one side of the phone case is removed, a worm gear rotating motor is activated to drive the worm gear to rotate. The worm gear drives the worm wheel to rotate, which in turn rotates the rotating seat, causing the clamping seat and the phone case to rotate 180 degrees, removing the parting line on the other side. This not only saves time and effort and improves production efficiency but also reduces the labor intensity and risk of injury for workers. Attached Figure Description

[0026] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0029] Reference Figure 1-9The deburring and polishing device for mobile phone cases includes a processing table 1. A multi-axis adjusting seat 2 and a clamping table 4 are respectively located at the top two ends of the processing table 1. A water jet nozzle 3 is fixed to the bottom surface of the multi-axis adjusting seat 2. A rotating seat 7 is rotatably connected to the inner wall of the clamping table 4. A clamping seat 8 is detachably connected to one side of the rotating seat 7. A lead screw 9 is connected to the side wall of the clamping seat 8 via a bearing. Both ends of the lead screw 9 are threadedly connected to clamping suction cups 6, which are slidably connected to the inner wall of the clamping seat 8. The lead screw 9 is driven by a motor 10. A worm gear 17 is fixed to the other side of the rotating seat 7. A worm 18 meshes with the surface of the worm gear 17. The end bearing is connected to the bearing housing. The worm 18 is driven by the worm rotation motor 19. Both the bearing housing and the worm rotation motor 19 are fixed on the surface of the clamping table 4. The helix angle of the worm 18 is less than the equivalent friction angle between the meshing teeth of the worm 18 and the worm wheel 17. When the helix angle of the worm 18 is less than the equivalent friction angle between the meshing teeth of the worm 18 and the worm wheel 17, the worm wheel and worm structure has self-locking property. That is, the worm 18 can drive the worm wheel 17 to rotate, but the worm wheel 17 cannot drive the worm 18 to rotate. This improves the stability of the rotating table 7 and prevents the impact force of the water jet from causing the rotating table 7 to shake.

[0030] The rotary base 7 has slots 701 on its side, and each slot 701 has a limiting groove on its side wall. A slider 13 is slidably connected inside the limiting groove. A limiting roller 12 is provided on the side of the slider 13. Both sides of the limiting roller 12 are fixedly connected to the slider 13 to prevent the limiting roller 12 from sliding or rolling relative to each other, thereby improving the stability between the rotary base 7 and the clamping seat 8. A limiting spring 14 is fixed between the slider 13 and the side wall of the limiting groove. A plug 11 is fixed on the side of the clamping seat 8, and a semi-circular locking groove is formed on the surface of the plug 11. A rubber sleeve is bonded to the inner wall of the semi-circular locking groove and the surface of the limiting roller 12. The rubber sleeve not only increases the friction between the semi-circular locking groove and the limiting roller 12, further improving the stability between the rotary base 7 and the clamping seat 8, but also plays a protective role, reducing the wear of the limiting roller 12. Since the clamping seat 8 needs to continuously clamp the phone case, it requires regular maintenance after long-term operation to avoid affecting the processing of the phone case. To address this issue, this utility model adopts a detachable structure. During installation, the plug 11 on the side of the clamping seat 8 is inserted into the slot 701 on the side of the rotating seat 7. The plug 11 presses against the limiting roller 12 until the plug 11 is fully inserted into the slot 701. Under the action of the limiting spring 14, the limiting roller 12 engages with the semi-circular locking groove on the surface of the plug 11, improving the tightness between the clamping seat 8 and the rotating seat 7. During disassembly, the clamping seat 8 can be pulled out by force. The disassembly and assembly are convenient, the operation is simple, and the clamping mechanism is easy to maintain.

[0031] The inner wall of the slot 701 is arrayed with a second limiting groove. A limiting protrusion 15 is slidably connected inside the second limiting groove. A compression spring 16 is fixed between one side of the limiting protrusion 15 and the side wall of the second limiting groove. When the clamping seat 8 is connected to the rotating seat 7, the limiting protrusion 15 is further squeezed by the plug 11. Finally, under the action of the compression spring 16, the plug 11 is tightly locked, which further improves the tightness between the plug 11 and the slot 701. The other side of the limiting protrusion 15 is set as a hemispherical shape to facilitate the plug 11 to enter the slot 701.

[0032] The working principle of this utility model is as follows: Insert the plug 11 on the side of the clamping seat 8 into the slot 701 on the side of the rotating seat 7. The plug 11 squeezes the limiting roller 12 until the plug 11 is fully inserted into the slot 701. Under the action of the limiting spring 14, the limiting roller 12 and the semi-circular locking groove on the surface of the plug 11 are engaged. Then, the phone case is clamped by the clamping suction cup 6. Turn on the motor 10 to drive the lead screw 9 to rotate. The lead screw 9 drives the clamping suction cup 6 to move towards each other, thereby clamping the phone case. Then, turn on the water jet nozzle 3 to remove the parting line. The multi-axis adjusting seat 2 adjusts the direction of the nozzle on the x, y, and z axes. After the parting line on one side of the phone case is removed, turn on the worm gear rotating motor 19 to drive the worm gear 18 to rotate. The worm gear 18 drives the worm wheel 17 to rotate, thereby driving the rotating seat 7 to rotate. This causes the clamping seat 8 and the phone case to rotate 180 degrees, removing the parting line on the other side. When inspecting the clamping mechanism, simply pull out the clamping seat 8.
