Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a burr removal device. Background Technology

[0002] With the continuous development of electronic devices, the processing quality of mid-frame products, as an important component, has a crucial impact on the overall performance and appearance of the product. Among the processing steps for mid-frame products, the machining of microphone holes is particularly critical. Microphone holes are small holes in mid-frame products used to mount components such as microphones; their diameter is typically 0.6–1.2 mm, and their depth is 4–6 mm. Due to the small diameter and deep depth of microphone holes, burrs and debris are easily left behind during processing. This not only affects the appearance quality of the product but may also adversely affect subsequent assembly and use.

[0003] Currently, the cleaning of burrs and debris inside the mesh holes is mainly done manually. A typical mid-frame product has 2-3 mesh holes, requiring each hole to be cleaned and inspected individually. This manual cleaning and inspection method has several problems: First, the manual operation is cumbersome, requiring a lot of manpower and time, resulting in low production efficiency; second, manual cleaning cannot guarantee that burrs and debris inside each hole are completely removed, easily leading to incomplete cleaning; third, frequent manual operation increases the risk of damage to the product's appearance, such as scratches and bumps, affecting the overall appearance quality of the product. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a burr removal device that, through automation and optimized design, significantly improves production efficiency and product quality, and reduces labor costs and product damage risks.

[0005] To solve the above-mentioned technical problems, the present invention provides a burr removal device, including a fixed platform and a cleaning mechanism. The fixed platform is provided with a fixing component for fixing the product, and the cleaning mechanism includes a burr cleaning needle and a driving component. The burr cleaning needle can move along the axial direction of the concave hole on the product to clean the concave hole.

[0006] Furthermore, the product has a through cavity in the middle; the fixing component includes a positioning block protruding from the upper end face of the fixing platform corresponding to the position of the through cavity, the positioning block being used to insert into the through cavity to position the product.

[0007] Furthermore, the fixing assembly also includes an air pump and several suction nozzles, the suction nozzles being disposed on the fixing platform at positions corresponding to the product placement, and each suction nozzle being connected to the air pump via an air pipe.

[0008] Furthermore, the fixing component also includes a sensor, which is disposed on the fixing platform at the position corresponding to the product placement position. The sensor is connected to the air pump via a signal. When the product is placed on the fixing platform, the surface of the fixing platform is provided with a sensor, which is connected to the air pump circuit. The start and stop status of the air pump is triggered by the sensor.

[0009] Furthermore, the driving component is a cylinder, which is fixedly mounted on one side of the fixed platform, and the output shaft of the cylinder extends toward the corresponding concave hole. The burr removal needle is fixedly mounted at the end of the output shaft of the cylinder.

[0010] Furthermore, a limiting block is fixedly provided on the fixed platform at the position corresponding to the position between the cylinder and the product. A limiting hole is provided on the limiting block. The inner wall of the limiting hole is clearance-fitted with the outer wall of the output shaft. The output shaft extends into the limiting hole from the end away from the product and extends out from the end of the limiting hole facing the concave hole. The burr removal needle is fixedly provided at the end of the output shaft that extends out of the limiting hole.

[0011] Furthermore, a helical spring is fitted onto a section of the output shaft located between the cylinder and the limiting block, with both ends of the helical spring fixed to the cylinder housing and the side of the limiting block, respectively.

[0012] Furthermore, it also includes a monitoring mechanism for observing the burr removal process. The monitoring mechanism includes a digital magnifying glass and a display screen. The digital magnifying glass is positioned corresponding to the location of the recess to observe the cleaning process of the recess. The data cable of the digital magnifying glass is connected to the display screen.

[0013] Furthermore, it also includes a base and a bracket mounted on the base, with the fixing platform and the digital magnifying glass both mounted on the bracket.

[0014] Furthermore, the brackets are configured as two sets symmetrically arranged along the width direction of the fixed platform. The upper ends of the two sets of brackets are respectively connected to the two ends of the fixed platform, and the lower ends of the two sets of brackets are connected to the base. Each bracket includes a vertical plate arranged along the length direction of the fixed platform and two columns. The two columns are located on the base at positions corresponding to the two ends of the fixed platform, and the vertical plate is located between the two columns.

[0015] The digital magnifying glass is mounted on two columns located at the same end of the fixed platform. Each column is provided with a first fixing block.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The burr removal device of this utility model includes a base 1 and a fixing platform 2 for fixing a product 4. The fixing platform 2 is mounted on the base 1 via a bracket 3. The product 4 is a mid-frame product 4, with a through cavity 41 in the middle, and recesses 42 for mounting components such as microphones are provided on the outer wall of the product 4. The base 1 and the fixing platform 2 are also provided with fixing components 5 for fixing the product 4, a cleaning mechanism 6 for cleaning burrs in the recesses 42, and a monitoring mechanism 7 for observing the burr cleaning process.

[0027] The base 1 is placed horizontally on the ground, and the supports 3 are configured in two sets symmetrically arranged along the width direction of the base 1. The upper ends of the two sets of supports 3 are respectively connected to the two ends of the fixed platform 2, and the lower ends of the two sets of supports 3 are connected to the base 1. Each support 3 includes a vertical plate 31 arranged along the length direction of the base 1 and two columns 32. The two columns 32 are vertically arranged on the base 1 at positions corresponding to the two ends of the fixed platform 2, and the vertical plate 31 is located between the two columns 32.

[0028] The fixed platform 2 is horizontally positioned above the two sets of brackets 3. Please refer to... Figure 4The fixing component 5 includes a support block 51, a positioning block 52, an air pump, a suction nozzle 53, and a sensor 54. The support block 51 protrudes from the center of the upper surface of the fixing platform 2, and is used to directly contact and support the product 4. The support block 51 is rectangular in shape to match the product 4, and its size is smaller than that of the product 4. This arrangement ensures that when the product 4 is placed on the support block 51, the edge of the product 4 protrudes outside the support block 51, and the recess 42 is also located outside the support block 51, facilitating the operation of the cleaning mechanism 6. The positioning block 52 protrudes from the center of the upper surface of the support plate, corresponding to the position of the through cavity 41. The positioning block 52 matches the through cavity 41, and when the product 4 is placed on the fixing platform 2, the positioning block 52 is inserted into the through cavity 41 to position the product 4. The number of suction nozzles 53 is configured to be several, and each suction nozzle 53 is mounted on the tray. Specifically, the upper end of the tray has a plurality of first grooves 55 recessed downwards, and the suction nozzles 53 are correspondingly arranged in the plurality of first grooves 55 with their openings facing upwards to adsorb the product 4. Each suction nozzle 53 is connected to an external air pump (not shown in the figure) through an air tube. The air pump draws air so that the suction nozzles 53 can adsorb the lower end surface of the product 4, thereby fixing the product 4. The sensor 54 is disposed on the tray. Specifically, the upper end of the tray has a second groove 56 recessed downwards, and the sensor 54 is disposed in the second groove 56. At the same time, the sensor 54 is connected to the air pump circuit, and the start and stop status of the air pump is triggered by the sensor 54. When the product 4 is placed on the fixed platform 2, the sensor 54 sends a signal to the air pump, which draws air to cause the suction nozzles 53 to adhere to the product 4. Furthermore, in the illustrated embodiment, the suction nozzles 53 are accordion nozzles 53. Compared to ordinary suction nozzles 53, accordion nozzles 53 have the following advantages: better sealing performance, adaptability to uneven surfaces, and reduced risk of air leakage; simultaneously, their unique folding structure makes them more flexible, adaptable to different suction angles and positions, and better disperses force when subjected to external impact, reducing damage. In addition, accordion nozzles 53 are made of durable materials, have a larger suction range, and a longer service life; these advantages make them perform better in practical applications.

[0029] The product 4 has multiple recesses 42, all of which are located at the edge of the product 4. The cleaning mechanism 6 has several groups that correspond one-to-one with the multiple recesses 42. The recesses 42 of the product 4 are located at both ends along the length of the product 4; therefore, the several groups of cleaning mechanisms 6 are respectively arranged at both ends of the fixed platform 2.

[0030] The fixed platform 2 is provided with extension platforms 61 at positions corresponding to both ends of the product 4. Each extension platform 61 is fixed to the lower end face of the fixed platform 2 and extends outward along the length of the product 4. The extension platforms 61 are used to mount the cleaning mechanism 6. Please refer to... Figure 5 Each of the cleaning mechanisms 6 includes a deburring needle 62 and a driving member 63. Driven by the driving member 63, the deburring needle moves in the direction of extending into or withdrawing from the recess 42 to clean the corresponding recess 42. Specifically, the driving member 63 is mounted on the upper end face of the extension platform 61, and the output shaft of the driving member 63 can extend or retract along the inclined direction of the recess 42. A clearance groove 64 is provided on the fixed platform 2 at the position corresponding to the extension of the output shaft of the driving member 63 to allow the output shaft to pass through. A limiting block 65 is provided on the bottom wall of the clearance groove 64, and the limiting block 65 is located between the driving member 63 and the product 4. A limiting hole 66 is provided on the limiting block 65 along the length direction of the product 4, and the opening direction of the limiting hole 66 is consistent with the extension direction of the output shaft to allow the output shaft to pass through it. The inner wall of the limiting hole 66 is clearance-fitted with the outer wall of the output shaft. The output shaft extends into the limiting hole 66 from the end furthest from the product 4 and extends out from the end facing the recess 42. Because the recess 42 is small and the deburring needle 62 is thin, the limiting hole 66 assists in positioning the deburring needle 62. The deburring needle 62 is mounted on the end of the output shaft extending from the limiting hole 66 via a pin. The pin connection allows the user to replace the deburring needle 62 as needed. A coil spring 67 is fitted onto a section of the output shaft between the cylinder and the limiting block 65. One end of the coil spring 67 abuts against the drive member 63, and the other end abuts against the side wall of the limiting block 65. The coil spring 67 absorbs the impact force during the movement of the drive member 63, reducing the impact on the deburring needle 62 and thus preventing damage to the recess 42; it also adjusts the output force, as the spring force of the coil spring 67 can offset part of the load, making the movement of the output shaft smoother. In the illustrated embodiment, the drive element 63 is a cylinder.

[0031] The monitoring mechanism 7 includes a digital magnifying glass 71 and a display screen (not shown in the figure). The digital magnifying glass 71 has several holes corresponding one-to-one with several recesses 42. The digital magnifying glass 71 is positioned at the location corresponding to the recesses 42 to observe the cleaning status of the recesses 42. Specifically, the digital magnifying glass 71 is fixedly mounted on the bracket 3. Two columns 32 located at the same end of the fixed platform 2 are each provided with a first fixing block 72. A horizontal crossbar 73 is provided between the two first fixing blocks 72, and a second fixing block 74 is provided in the middle of the crossbar 73. A through-hole is opened in the middle of the second fixing block 74, and a first fixing rod 75 is inserted through the hole. A slot is opened at the end of the fixing rod, and a second fixing rod 76 is inserted into the slot. A mounting block 77 is fitted around the outer periphery of the digital magnifying glass 71, and the mounting block 77 is inserted into the end of the second fixing rod 76 so that the lens of the digital magnifying glass 71 faces upwards to observe the condition of the recesses 42. Each of the digital magnifying glasses 71 has a data cable connected to the display screen so that the image captured by the digital magnifying glasses 71 can be projected onto the display screen.

[0032] One embodiment of the burr removal device of this utility model operates as follows: In use, the product 4 to be cleaned is placed on the tray, and the positioning block 52 positions the product 4. When the product 4 is lowered, the sensor 54 senses the product 4 and sends a signal to the air pump. Several air nozzles then attract the product 4 to further restrict its movement. The cylinder is activated, causing its output shaft to extend into the corresponding recess 42 and remove the burrs, thereby cleaning the recess 42. During the cleaning process, the digital magnifying glass 71 continuously photographs the recess 42, allowing the user to observe the condition inside the recess 42 at any time via the display screen to determine whether the recess 42 has been cleaned.

[0033] Compared with existing technologies, this utility model's burr removal device significantly improves the cleaning efficiency and quality of perforations in mid-frame products through an automated cleaning mechanism and monitoring system. This device not only reduces manual intervention and lowers labor costs, but also ensures that every perforation is thoroughly cleaned through precise cleaning needles and real-time monitoring, while protecting the product's appearance and reducing potential damage during the cleaning process. These optimized designs significantly improve production efficiency and product quality, enhance overall quality control, and give the device high application value and market competitiveness in actual production.
