Description

Technical Field

[0001] This invention relates to the field of VCM cutting technology, specifically to an adjustable automatic VCM cutting mechanism. Background Technology

[0002] The VCM base is an important component of the miniature camera. When processing the VCM base, it is usually necessary to cut the sprue on the injection edge of the product. Therefore, in order to improve the cutting effect of the VCM base, an automatic cutting mechanism is often used.

[0003] For example, a fully automatic VCM base cutting machine disclosed in CN217098733U includes a chassis, a man-machine box installed on the top of the chassis, and a tail material cutting machine installed on the rear side of the man-machine box. A material pulling ratchet is installed on one side of the tail material cutting machine, and a good product cutting machine is set on one side of the material pulling ratchet. A material transfer module is installed on the right side of the tail material cutting machine, and a defective product cutting machine is set on the right side of the material transfer module. A vision inspection is installed on one side of the defective product cutting machine, and a sprue cutting machine is set on one side of the vision inspection machine. A front-end feeding machine is installed below the sprue cutting machine.

[0004] The existing technologies mentioned above have the following technical problems: When cutting VCM, the existing cutting mechanisms usually only allow for the replacement of parts and adjustment of process parameters. Operators rely on visual observation, which leads to operational errors. Moreover, parts are easily damaged during operation, making the operation difficult. In addition, while a visual inspection module is set up to detect defective VCM products during the VCM cutting process, it is not convenient to automatically clean the dust and impurities attached to the VCM during inspection. As a result, some dust adheres to the surface of the VCM, causing the visual inspection module to make misjudgments.

[0005] Therefore, we propose an adjustable VCM automatic cutting mechanism to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable automatic VCM cutting mechanism to solve the problems mentioned in the background art. Currently available cutting mechanisms on the market can only adjust process parameters by changing parts when cutting VCM, and the operator relies on visual observation, which is prone to operational errors and damage to parts during operation, making operation difficult. In addition, while a vision inspection module is set up to detect defective VCM products during the cutting process, it is not convenient to automatically clean the dust and impurities attached to the VCM during inspection, resulting in some dust adhering to the surface of the VCM and causing the vision inspection module to make misjudgments.

A limiting block is fixedly installed on the mounting plate. A blower hood is provided below the limiting block, and a visual inspection camera for detecting unqualified VCM products is installed on the side of the blower hood. A guide shaft is installed through the upper end of the blower shroud. A servo motor is fixedly connected inside the blower shroud, and a fan is fixedly connected below the output end of the servo motor. A supplementary lighting mechanism is installed on the side of the limiting block to provide a bright light source for the visual inspection camera when the light is dim.

[0008] Preferably, the abutment rod is configured as a columnar structure, and the outer wall of the abutment rod and the inner wall of the guide groove are in contact with each other, and the guide groove is configured as an inclined structure.

[0009] By adopting the above technical solution, when the abutment rod moves back and forth, it can squeeze the guide groove of the inclined structure, so that the lifting slider can move up or down for adjustment.

[0010] Preferably, the interior of the blower hood is a hollow structure, and air outlets are evenly distributed at the bottom of the blower hood, with the air outlets communicating with the interior of the blower hood.

[0011] By adopting the above technical solution, the interior of the blower hood and the air outlet are interconnected, so that the air source inside the blower hood can be discharged outward through the air outlet and blown onto the surface of the VCM product.

[0012] Preferably, a cam is fixedly connected to the output end of the servo motor, and a main airbag is provided on the outer side of the cam. The main airbag is connected to an adjusting airbag through a connecting pipe, and the adjusting airbag is located on the side of the blower cover. A heat dissipation pipe is installed on the lower side of the main airbag, and the air outlet of the heat dissipation pipe faces the vision inspection camera.

[0013] Preferably, the adjusting airbag is bonded to the side of the blower cover, the blower cover can rotate around the guide shaft, and the connecting pipe between the adjusting airbag and the main airbag is a flexible tube.

[0014] By adopting the above technical solution, when the airflow inside the main airbag enters the regulating airbag, the regulating airbag can expand and push the blower cover to rotate around the guide shaft.

[0015] Preferably, the inner surface of the main airbag is provided with multiple wavy protrusions, and the main airbag is fixed inside the blower cover. The main airbag is made of elastic rubber material.

[0016] By adopting the above technical solution, the wavy protrusions on the inner surface of the main airbag can be squeezed by the cam.

[0017] Preferably, the supplementary lighting mechanism comprises a supplementary light, a heat-conducting column, a water-absorbing pipe, a water tank, a semiconductor cooling chip, a pushing airbag, an adjusting block, a piston column, and a positioning magnetic block. The supplementary light is fixed to the side of the limiting block. A heat-conducting column is fixedly connected to the supplementary light and extends into the interior of the limiting block. A water tank is provided inside the limiting block, and a semiconductor cooling chip is fixedly connected inside the water tank. The interior of the heat-conducting column is connected to the water tank through the water-absorbing pipe. A pushing airbag is installed on the heat-conducting column. An adjusting block is installed on the side of the pushing airbag and is sleeved on the heat-conducting column. A piston column is installed inside the heat-conducting column, and a positioning magnetic block is fixedly connected to the end of the piston column and the adjusting block.

[0018] Preferably, the push airbag is filled with thermally expanding gas, and the push airbag is located between the adjusting block and the heat-conducting column, with the adjusting block and the push airbag being fixedly connected.

[0019] By adopting the above technical solution, when the heat-conducting column absorbs the heat from the supplementary light, it can transfer the heat to the pushing airbag, and the expansion of the pushing airbag will push the adjusting block to move.

[0020] Preferably, the adjusting block can slide on the heat-conducting column, and the positioning magnetic block inside the adjusting block and the positioning magnetic block at the end of the piston column have opposite magnetic properties, and the piston column and the heat-conducting column are seamlessly connected inside.

[0021] By adopting the above technical solution, when the adjusting block moves, the positioning magnetic block can be used to make the piston rod move synchronously inside the heat-conducting column.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the adjustable VCM automatic cutting mechanism can accurately adjust the corresponding process parameter requirements by adjusting the scale connected to the inclined tail and changing the up and down movement of the module. At the same time, it can avoid the deviation of the detection results caused by the adhesion of dust and impurities when visually inspecting VCM. 1. Equipped with a lifting slider, the push block can be moved synchronously with the abutment rod by adjusting the scale. When the abutment rod moves, it can squeeze the inclined guide groove, so that the lifting slider can move up or down. This changes the up and down movement of the module, which can accurately adjust the corresponding process parameter requirements, thereby changing the process quality consistency and effectively eliminating the operator's debugging error. 2. Equipped with a blower hood, the fan generates airflow, which is then blown outward through the air outlet at the bottom of the blower hood. This airflow automatically cleans impurities from the surface of the VCM product. Simultaneously, the cam's rotation and reciprocating compression of the main airbag allows some of the airflow inside to enter the regulating airbag through the connecting pipe. By adjusting the expansion and contraction of the airbag, the blower hood can rotate back and forth around the guide shaft, thereby increasing the blowing range of the blower hood. At the same time, some of the airflow inside the main airbag can be blown towards the vision inspection camera through the heat dissipation pipe. The cool airflow ejected through the heat dissipation pipe can cool down the vision inspection camera, preventing it from overheating. 3. Equipped with a supplementary light, the supplementary light provides a light source for the visual inspection camera in low-light conditions. When the supplementary light generates heat after prolonged illumination, the heat-conducting column absorbs the heat and transfers it to the pushing airbag. The expansion of the airbag after absorbing heat allows the adjusting block to move the piston column inside the heat-conducting column using the positioning magnetic block. After the piston column moves, the suction pipe draws cold water from the water tank into the heat-conducting column, achieving automatic cooling of the heat-conducting column and the supplementary light. Furthermore, the suction pipe increases the water flow rate, improving the cooling rate of the water by the semiconductor cooling chip. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-8 The present invention provides the following two embodiments: Example

[0027] Existing cutting mechanisms for VCM typically only allow for component replacement and process parameter adjustment during VCM cutting, relying on visual inspection by the operator, which introduces operational errors and increases the risk of component damage. Furthermore, while visual inspection modules are used to detect defective VCM products, they struggle to automatically clean dust and impurities adhering to the VCM surface. This results in dust accumulation on the VCM surface, causing misjudgments by the visual inspection module. To address this technical problem, this embodiment discloses the following technical content: Figure 1-4 As shown; An adjustable VCM automatic cutting mechanism includes a base 1, a push block 2 mounted on the upper end of the base 1, a scale 3 mounted on the right side of the push block 2, a mounting plate 7 above the push block 2, a support column 8 mounted in the middle of the mounting plate 7, a fixed cutter 9 mounted below the support column 8, and lateral cutters 10 on the left and right sides of the fixed cutter 9. The mounting plate 7 is used to support the VCM product to be cut. A lifting slider 4 is mounted on the side of the push block 2, a guide groove 5 is formed on the lifting slider 4, and an abutment rod 6 is provided inside the guide groove 5. The device is fixed on the push block 2; the limiting block 11 is fixedly installed on the mounting plate 7, and a blower shroud 12 is provided below the limiting block 11, and a vision inspection camera 13 for inspecting unqualified VCM products is installed on the side of the blower shroud 12; the guide shaft 14 is installed through the upper end of the blower shroud 12, and a servo motor 15 is fixedly connected inside the blower shroud 12, and a fan 16 is fixedly connected below the output end of the servo motor 15; the abutment rod 6 is set as a columnar structure, and the outer wall of the abutment rod 6 and the inner wall of the guide groove 5 are in contact with each other, and the guide groove 5 is set as an inclined structure. The interior of the blower shroud 12 is set as a hollow structure, and air outlets are evenly distributed at the bottom of the blower shroud 12, and the air outlets are interconnected with the interior of the blower shroud 12.

[0028] The working principle of this embodiment is as follows: During use, the push block 2 is moved by adjusting the scale 3. After the push block 2 moves, the abutment rod 6 moves synchronously. The movement of the abutment rod 6 can squeeze the inclined guide groove 5, thereby causing the lifting slider 4 to move up or down. By changing the up and down movement of the module by the movement of the lifting slider 4, the corresponding process parameter requirements can be accurately adjusted, thereby changing the process quality consistency and effectively eliminating the operator's debugging error. When cutting the VCM product on the mounting plate 7, the servo motor 15 is turned on. The servo motor 15 turns the fan 16, thereby causing the air outlet at the lower end of the blower hood 12 to spray air out. The sprayed air is used to automatically clean the impurities on the surface of the VCM product. The cleaned VCM is inspected by the vision inspection camera 13, thereby realizing the detection of defective VCM during cutting. Example

[0029] The adjustable VCM automatic cutting mechanism disclosed in this embodiment is a further improvement based on the first embodiment described above. Existing cutting mechanisms, when inspecting defective products using a CCD camera, are prone to overheating due to prolonged operation, which reduces their lifespan. Furthermore, when cleaning impurities from the VCM product surface with airflow, the fixed airflow range reduces the cleaning effect. Additionally, in low-light conditions, it is difficult to provide supplemental lighting for the CCD camera, leading to poor visibility and affecting normal camera detection. To further address these technical problems, this embodiment discloses the following technical content: Figure 1 and Figure 3-8 As shown; A supplementary lighting mechanism 22, installed on the side of the limiting block 11, provides a bright light source for the visual inspection camera 13 in low light conditions. A cam 17 is fixedly connected to the output end of the servo motor 15, and a main airbag 18 is provided on the outer side of the cam 17. The main airbag 18 is interconnected with an adjusting airbag 20 through a connecting pipe 19, and the adjusting airbag 20 is located on the side of the blower cover 12. A heat dissipation pipe 21 is installed on the lower side of the main airbag 18, and the air outlet of the heat dissipation pipe 21 faces the visual inspection camera 13. The adjusting airbag 20 is bonded to the side of the blower cover 12, and the blower cover 12 can rotate around the guide shaft 14. The connecting pipe 19 connecting the adjusting airbag 20 and the main airbag 18 is a flexible hose. The inner surface of the main airbag 18 is provided with multiple corrugated protrusions, and the main airbag 18 is fixed inside the blower cover 12. The main airbag 18 is made of elastic rubber. The supplementary lighting mechanism 22 consists of a supplementary light 2201, a heat-conducting column 2202, a water suction pipe 2203, a water tank 2204, a semiconductor cooling chip 2205, a pushing airbag 2206, an adjusting block 2207, a piston column 2208, and a positioning magnetic block 2209. The supplementary light 2201 is fixed to the side of the limiting block 11. The heat-conducting column 2202 is fixedly connected to the supplementary light 2201 and extends into the interior of the limiting block 11. The interior of the limiting block 11 is equipped with a water tank 2204. A semiconductor cooling chip 2205 is fixedly connected inside component 04. The interior of the heat-conducting column 2202 is connected to the water tank 2204 via a water suction pipe 2203. A pushing airbag 2206 is installed on the heat-conducting column 2202, and an adjusting block 2207 is installed on the side of the pushing airbag 2206. The adjusting block 2207 is sleeved on the heat-conducting column 2202. A piston column 2208 is installed inside the heat-conducting column 2202. Positioning magnetic blocks 2209 are fixedly connected to the end of the piston column 2208 and the adjusting block 2207. The pushing airbag 2206 is filled with thermal expansion gas and is located between the adjusting block 2207 and the heat-conducting column 2202. The adjusting block 2207 and the pushing airbag 2206 are fixedly connected. The adjusting block 2207 can slide on the heat-conducting column 2202, and the positioning magnetic block 2209 on the inner side of the adjusting block 2207 and the positioning magnetic block 2209 at the end of the piston column 2208 have opposite magnetic properties, and the piston column 2208 and the heat-conducting column 2202 are seamlessly connected inside.

[0030] The working principle of this embodiment is as follows: When the fan 16 sprays air outward through the air outlet at the lower end of the blower shroud 12, the output end of the servo motor 15 rotates, which drives the cam 17 on it to rotate synchronously. When the cam 17 rotates, it can intermittently squeeze the convex peaks on the inner surface of the main airbag 18. When the main airbag 18 is compressed, part of the airflow inside it can be discharged into the regulating airbag 20 through the connecting pipe 19, while another part of the airflow is sprayed onto the vision inspection camera 13 through the heat dissipation pipe 21. The airflow sprayed out by the heat dissipation pipe 21 can cool down the vision inspection camera 13 and prevent the vision inspection camera 13 from being in an overheated state. The airflow enters the regulating airbag 20. After internal rotation, the regulating airbag 20 expands, causing the blower shroud 12 to rotate around the guide shaft 14. When the cam 17 disengages from the wave-shaped protrusion on the inner surface of the main airbag 18, the airflow inside the regulating airbag 20 flows back into the main airbag 18. The regulating airbag 20 then contracts, pulling the blower shroud 12 back to its original position. This allows for the reciprocating rotation of the blower shroud 12, increasing the airflow range and improving the cleaning effect on the VCM surface. In low visibility conditions, the supplementary light 2201 is activated to provide illumination for the visual inspection camera 13 to perform its inspection. When the supplementary light 2201 generates heat after prolonged illumination, the heat is absorbed by the heat-conducting column 2202 and transferred to the pushing airbag 2206. The expansion of the airbag 2206 after absorbing heat allows the adjusting block 2207 to slide on the heat-conducting column 2202. Once the adjusting block 2207 moves, the inner positioning magnet 2209 drives the piston column 2208 to move inside the heat-conducting column 2202. After the piston column 2208 moves, the heat-conducting column 2202 can use the water suction pipe 2203 to draw cold water from the water tank 2204 into its interior, thus cooling both the heat-conducting column 2202 and the supplementary light 2201. After the temperature of the heat-conducting column 2202 decreases, it pushes the airbag 2206 to contract, thereby pulling the adjusting block 2207 to reset. After the adjusting block 2207 is reset, the positioning magnetic block 2209 can be used again to make the piston column 2208 reset as well. After the piston column 2208 is reset, the water source of its heat-conducting column 2202 can be squeezed back into the water tank 2204. This reciprocating rotation not only ensures that the supplementary light 2201 is kept at a low temperature, but also accelerates the flow of water in the water tank 2204 by the water intake and drainage of the water pipe 2203, thereby increasing the cooling rate of the water source in the water tank 2204 by the semiconductor cooling chip 2205.
