Description

Technical Field

[0001] This utility model relates to the field of electronic product manufacturing technology, and in particular to a silicone molding line processing device for electronic products with positioning and fixing components. Background Technology

[0002] Silicone mold lines in electronic products are weld lines formed by overflow of silicone during the production process. They are a product of mold design and process. If not treated, they will affect the product assembly accuracy (such as silicone button jamming), appearance quality (such as edge burrs) and user experience. Among them, slight mold lines will be generated during the production of precision silicone parts such as mobile phone cases, smart wearable device sealing rings, and electronic connectors. A light-colored groove or ripple can be seen on the surface of the silicone product.

[0003] Silicone components for electronic products are widely used in consumer electronics and communication equipment due to their excellent insulation, temperature resistance, and sealing properties. Parting lines, as unavoidable process marks during silicone molding, directly affect the assembly accuracy and appearance of the product. Existing processing technologies have some shortcomings. Grinding components are mostly fixed in position or manually adjusted, unable to flexibly adjust their left and right positions according to the product width. When processing parting lines on the opposite side of the product, manual disassembly, flipping, and repositioning are required, which is not only time-consuming but also prone to product displacement due to manual operation, causing the grinding position to deviate from the parting line and affecting processing accuracy. Therefore, we propose an electronic product silicone parting line processing device with positioning and fixing components to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a silicone molding line processing device for electronic products with positioning and fixing components, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A silicone mold line processing device for electronic products with positioning and fixing components includes a support platform. An adjustment mechanism is mounted on the bottom surface of the support platform, and a mold line pressing mechanism is mounted on the top of the adjustment mechanism. A side frame is fixedly connected to the upper surface of the support platform, and a grinding component is disposed inside the side frame. The adjustment mechanism includes a mounting bracket fixedly connected to the bottom surface of the support platform, and a servo motor is installed inside the mounting bracket. A transmission rod is fixedly connected to the output end of the servo motor. An annular slide rail is fixedly connected to the upper surface of the support platform, and two guide rods are slidably connected inside the annular slide rail. The top ends of the two guide rods are fixedly connected to a placement platform. The top end of the transmission rod is fixedly connected to the bottom surface of the placement platform. The mold line pressing mechanism includes a side bracket fixedly connected to the placement platform. A drive cylinder is fixedly connected to the upper surface of the side bracket, and a connecting plate is fixedly connected to the output end of the drive cylinder. A U-shaped pressure rod is fixedly connected to the outer surface of the connecting plate. A chip suction component is mounted on the upper surface of the side frame.

[0006] In a further embodiment, a guide post is fixedly connected to the inner wall of the side bracket, and the connecting plate is slidably connected to the outer surface of the guide post.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This device uses a servo motor to drive the transmission rod and the placement platform to rotate smoothly 180° along the annular slide rail, achieving automatic product flipping without manual disassembly. The coordination between the annular slide rail and the transmission rod ensures accurate product positioning after flipping, avoiding positional deviations caused by manual flipping and ensuring the grinding accuracy of the mold line on the opposite side. In addition, the mold line pressing mechanism first fixes the product firmly, and the drive cylinder can push the connecting plate and the return pressure rod to press and fix the product on the placement platform, ensuring the stability of subsequent processing.

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.

[0019] Please see Figure 1-5In this utility model, an electronic product silicone molding line processing device with positioning and fixing components includes a support platform 1. An adjustment mechanism 3 is installed on the bottom surface of the support platform 1, and a molding line pressing mechanism 4 is installed on the top of the adjustment mechanism 3. A side frame 5 is fixedly connected to the upper surface of the support platform 1, and a grinding component 18 is provided inside the side frame 5. The adjustment mechanism 3 includes a mounting bracket 301 fixedly connected to the bottom surface of the support platform 1. A servo motor 302 is installed inside the mounting bracket 301, and a transmission rod 303 is fixedly connected to the output end of the servo motor 302. An annular slide rail 304 is fixedly connected to the upper surface of the support platform 1. Two guide rods 305 are slidably connected inside the annular slide rail 304. The tops of the two guide rods 305 are jointly fixedly connected to a placement platform 16. When the placement platform 16 rotates 180 degrees clockwise and then re-adjusts, it will rotate 180 degrees counterclockwise. Furthermore, when the placement platform 16 rotates, it will cause the guide rods 305 to rotate within the annular slide rail 304, ensuring proper placement. The stability of the platform 16 is ensured by the top end of the transmission rod 303 being fixedly connected to the bottom surface of the platform 16. The mold line pressing mechanism 4 includes a side bracket 401 fixedly connected to the platform 16. A drive cylinder 402 is fixedly connected to the upper surface of the side bracket 401. A connecting plate 403 is fixedly connected to the output end of the drive cylinder 402. A U-shaped pressure rod 404 is fixedly connected to the outer surface of the connecting plate 403. A guide post 405 is fixedly connected to the inner wall of the side bracket 401. The connecting plate 403 is slidably connected to the outer surface of the guide post 405. The drive cylinder 402 of the mold line pressing mechanism 4 drives the U-shaped pressure rod 404 to press the mold line. After the grinding component 18 completes the front grinding, the servo motor 302 drives the platform 16 to rotate 180° automatically. Without manual disassembly, it can accurately align with the mold line on the other end for pressing and grinding. Moreover, the guide post 405 restricts the movement trajectory of the connecting plate 403, ensuring that the U-shaped pressure rod 404 is vertical and stable during pressing, and avoiding uneven pressure.

[0020] A dust collection assembly 7 is installed on the upper surface of the side frame 5. The dust collection assembly 7 includes a negative pressure storage cylinder 71 fixedly connected to the side frame 5. A negative pressure fan 72 is installed at the top of the negative pressure storage cylinder 71. A dust collection hood 73 is fixedly connected to one side of the negative pressure storage cylinder 71 through a conduit. A sealing door is hinged to the front of the negative pressure storage cylinder 71 by a pin, which is convenient to open and clean the sucked-in debris and other debris. The negative pressure fan 72 of the dust collection assembly 7 generates negative pressure, and the dust collection hood 73 collects the silicone debris generated by polishing in real time, avoiding debris residue on the product surface or accumulation on the placement table 16, reducing manual cleaning time and ensuring product cleanliness.

[0021] A telescopic cylinder 8 is fixedly connected to the upper surface of the side frame 5. The output end of the telescopic cylinder 8 is located inside the side frame 5. A square frame 9 is fixedly connected to the output end of the telescopic cylinder 8. A 10 is slidably connected to the outer surface of the square frame 9. One end of the 10 is connected to the grinding component 18. An electric push rod 13 is fixedly connected to the inner wall of the square frame 9. The output end of the electric push rod 13 is fixedly connected to the grinding component 18. A vertical rail 14 is fixedly connected to the inner wall of the side frame 5. A sliding plate 15 is slidably connected to the outer surface of the vertical rail 14. The outer surface of the sliding plate 15 is fixedly connected to the outer surface of the square frame 9. The telescopic cylinder 8 drives the square frame 9 to move up and down to adapt to products of different heights. The sliding component 10 works with the square frame 9 to achieve the initial left and right adjustment of the grinding component 18. The electric push rod 13 precisely controls the left and right movement distance of the grinding component 18 to ensure that the grinding head 12 is accurately aligned with the mold parting line. The vertical rail 14 and the sliding plate 15 restrict the up and down movement trajectory of the square frame 9 to ensure smooth up and down movement.

[0022] The polishing assembly 18 includes a fixed frame 17, inside which a drive motor 11 is installed. The output end of the drive motor 11 is fixedly connected to a polishing head 12. The drive motor 11 drives the polishing head 12 to rotate at high speed, which can quickly remove silicone mold lines, resulting in high polishing efficiency and smooth edges. The fixed frame 17 ensures a stable connection between the drive motor 11 and the polishing head 12, preventing polishing position deviation caused by motor shaking during polishing. A support base 2 with an opening is fixedly installed on the bottom surface of the support platform 1, and a controller 6 is fixedly installed on the front of the side frame 5. The controller 6 is connected to a servo motor via wires. The motor 302, drive cylinder 402, negative pressure fan 72, telescopic cylinder 8, and electric push rod 13 are electrically connected. The support base 2 with opening enhances the stability of the support platform 1. The controller 6 centrally controls all electric components. It can be a PLC controller 6, which uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations. It controls various types of motion through digital or analog input and output, eliminating the need for manual operation and reducing the difficulty of operation. It is especially suitable for mass production scenarios.

[0023] The working principle of this utility model is as follows: When using it, first check whether the grinding head 12 is sharp, whether the circular slide rail 304 is lubricated, and whether the dust collection cover 73 is aligned with the grinding area. The controller 6 presets the following parameters: the servo motor 302 rotates at 180°, the pressure of the drive cylinder 402 is adjusted according to the product thickness, the grinding head 12 rotates at a certain speed, and the electric push rod 13 moves left and right. Place the electronic product component to be processed stably in the positioning area of ​​the placement table 16, ensuring the parting line faces upwards. Activate the parting line pressing mechanism 4, driving cylinder 402 to push the connecting plate 403 down along the guide column 405. The U-shaped pressure rod 404 presses against the product surface, flattening the product and achieving a firm fixation. Then, activate the telescopic cylinder 8 to push the square frame 9 down along the vertical rail 14, bringing the grinding head 12 close to the flattened parting line. Next, activate the electric push rod 13 to drive the grinding assembly 18 to move left and right along the square frame 9, precisely aligning it with the parting line at one end of the product. Finally, start the drive motor 1. 1. With the negative pressure fan 72, the grinding head 12 can rotate at high speed to grind the parting line. At the same time, the dust hood 73 collects silicone debris in real time. After grinding one end, the grinding motor and the dust suction fan are turned off, the servo motor 302 is started, and the transmission rod 303 drives the placement table 16 to automatically rotate 180° along the annular slide rail 304. The other end of the product faces the grinding component 18. After rotation, the servo motor 302 stops automatically, and the grinding steps are repeated. The position of the grinding component 18 is adjusted to complete the grinding of the parting line at both ends and the collection of debris. When the processing is completed, all parts are turned off, and the processed silicone product can be taken out.
