Description

Technical Field

[0001] This invention relates to the field of surface mount resistor processing technology, specifically to a pick-up device for screening surface mount resistors. Background Technology

[0002] Surface mount resistors are common components in electronic products. Their small size and high precision make them widely used in various circuit boards and electronic devices. Screening surface mount resistors during the manufacturing process is a crucial step in ensuring product quality and performance. To achieve efficient and accurate screening of surface mount resistors, pick-and-place devices are widely used.

[0003] As a key component in the screening of surface mount resistors, the pick-up device has functions such as pick-up, positioning, and conveying. It uses negative pressure to pick up surface mount resistors and place them at specific locations for subsequent processing or testing. With the continuous development of electronic products and the increasing market demands, pick-up devices are constantly being innovated and improved to adapt to the screening requirements of surface mount resistors of different sizes, shapes, and types.

[0004] However, existing suction devices require a long time to generate negative pressure by blowing air outwards with a fan, resulting in high energy consumption over extended periods. Furthermore, the negative pressure cannot be reused during use, leading to a significant increase in production costs and hindering enterprise production.

[0005] To address the aforementioned issues, a pick-up device for screening chip resistors is proposed. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a pick-up device for screening surface mount resistors, which solves the problem of high cost in the use of existing surface mount resistor screening and pick-up devices.

A suction plate is fixedly connected to the top of the suction plate, and multiple contactors are fixedly connected to the bottom of the suction plate. Multiple air pipes are fixedly connected to the top of the suction plate. Collection columns are fixedly connected to both sides of the support block. A production capacity cover is fixedly connected to the top of the collection column. A coil is provided on the inner wall of the production capacity cover. A rotating rod is rotatably connected to the top of the collection column. A permanent magnet is fixedly connected to the top of the outer wall of the rotating rod. Multiple impellers are installed on one side of the outer wall of the rotating rod. Conveying pipes are fixedly connected to adjacent sides of multiple collection columns. A power component is provided on the top of the displacement rod. A quick-release component is provided on one side of the quick-release block. A detection component is provided on the inner wall of the protective plate.

[0008] Preferably, the quick-release assembly includes a positioning plate, which is fixedly connected to one side of the quick-release block. An adjustment block is rotatably connected to one side of the positioning plate, a locking rod is fixedly connected to the bottom of the adjustment block, and a bolt is threadedly connected to one side of the positioning plate.

[0009] Preferably, the power assembly includes a first motor, which is fixedly connected to the top of the displacement rod. A first bevel gear is fixedly connected to the output end of the first motor. A first lead screw is rotatably connected to the inner wall of the displacement rod. A second bevel gear is fixedly connected to one side of the outer wall of the first lead screw. A second motor is fixedly connected to one side of the protective plate. A second lead screw is fixedly connected to the output end of the second motor.

[0010] Preferably, a one-way valve is provided at the bottom of the collection column, and the delivery pipe is fixedly connected to the output end of the negative pressure device body.

[0011] Preferably, the battery and the coil are electrically connected, and the coil is made of copper.

[0012] Preferably, the locking rod is slidably connected to both sides of the mating block, and the bolt is slidably connected to the top of the adjusting block.

[0013] Preferably, the first bevel gear and the second bevel gear are meshed, and the displacement rod is threaded to the outer wall of the second lead screw.

[0014] Preferably, the bearing block is threadedly connected to the outer wall of the first lead screw.

[0015] Preferably, the detection component includes a placement platform, which is fixedly connected to the inner wall of the protective plate, and a detector body is installed on the top of the placement platform. The battery is electrically connected to the detector body.

[0016] Preferably, the gas tube is a telescopic flexible hose for gas delivery.

[0017] Working Principle: When the operator uses this suction device to pick up and screen surface-mount resistors, the first conveyor belt sends the unscreened surface-mount resistors into the coverage area of ​​the suction device. The power components, the first motor and the second motor, respectively transmit power to the first lead screw and the second lead screw to ensure the positioning accuracy of the suction device. After the telescopic component inside the docking block completes the positioning, the negative pressure device body can be opened. The negative pressure generated by the built-in fan of the negative pressure device body outputs air force. Then, through the connection of multiple sets of air pipes, the surface-mount resistors can be stably attracted to the bottom of the contactor. During the process of the negative pressure passing through the collection column, the air pressure can drive the rotor connected to the impeller to generate rotational power. During the continuous rotation, the permanent magnet at the top of the rotor will continuously generate ionization in the coil, thereby realizing wind power generation. The generated electricity is collected into the battery through electrical connection, and the battery can power the detector body, thus realizing energy reuse and saving production costs.

[0018] Since different surface mount resistors have different sizes, when the suction plate needs to be replaced, the bolt can be unscrewed to release the position limit of the adjustment block and change the position of the adjustment block, so that the quick release block and the docking block can slide off. During the sliding off process, the air tube at the one-way valve connection can be removed and a new air tube and suction plate can be inserted to complete the whole replacement process.

[0019] This invention provides a pick-up device for screening surface mount resistors. It has the following advantages:

[0020] 1. This invention, through the combined use of components such as the capacity cover, rotating rod, permanent magnet, coil, impeller, and conveying pipe, can effectively utilize the negative pressure energy consumed during the use of the suction device, and reuse the collected energy, thereby effectively reducing the overall cost of the device.

[0021] 2. By using the combined use of components such as the first motor, the second motor, the first lead screw, and the second lead screw, this invention can accurately position the height between the contactor and the chip resistor during use, effectively replacing the traditional manual pick-up operation and improving screening efficiency.

[0022] 3. By using components such as positioning plates, adjusting blocks, locking rods, and bolts in combination, this invention can effectively improve the replacement speed of contactors and suction plates, allowing for quick replacement without the need for professional maintenance personnel, thus reducing labor costs.

[0032] The technical solution of the present invention will now be clearly and completely described 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.

[0033] Example:

[0034] Please see the appendix Figure 1 Appendix Figure 5 Appendix Figure 6 This invention provides a suction device for screening surface mount resistors, including a protective plate 1. A first conveyor belt 2 is installed inside the protective plate 1. A sorting track 3 is fixedly connected to the inner wall of the protective plate 1. A second conveyor belt 4 is installed on the front side of the protective plate 1. A displacement rod 5 is slidably connected to the top of the protective plate 1. A support block 6 is slidably connected to the top of the displacement rod 5. A negative pressure device body 7 is fixedly connected to the top of the support block 6. Batteries 8 are installed on both sides of the top of the support block 6. A docking block 30 is fixedly connected to the bottom of the support block 6. A telescopic component is provided at the bottom of the docking block 30. During suction, the contact height between the telescopic component and the surface mount resistor is adjusted to achieve the suction effect. Multiple quick-release blocks 10 are slidably connected to the inner wall of the docking block 30. A suction plate 9 is fixedly connected to the bottom, and multiple contactors 11 are fixedly connected to the bottom of the suction plate 9. Multiple air pipes 12 are fixedly connected to the top of the suction plate 9. The air pipes 12 use telescopic hoses for gas delivery. Collection columns 13 are fixedly connected to both sides of the bearing block 6. A capacity cover 14 is fixedly connected to the top of the collection column 13. A coil 17 is provided on the inner wall of the capacity cover 14. A rotating rod 15 is rotatably connected to the top of the collection column 13. A permanent magnet 16 is fixedly connected to the top of the outer wall of the rotating rod 15. Multiple impellers 18 are installed on one side of the outer wall of the rotating rod 15. A delivery pipe 19 is fixedly connected to the adjacent side of the multiple collection columns 13. A power component is provided on the top of the displacement rod 5. A quick-release component is provided on one side of the quick-release block 10. A detection component is provided on the inner wall of the protection plate 1.

[0035] The screened surface-mount resistors are conveyed to the coverage area of ​​the suction device via the first conveyor belt 2. The power transmission between the first motor 31 and the second motor 22 and the first lead screw 21 and the second lead screw 23, respectively, ensures the positioning accuracy of the suction device. After the telescopic component inside the docking block 30 completes the positioning, the negative pressure device body 7 can be opened. The negative pressure device body 7 generates negative pressure by outputting air force through its built-in fan. Then, through the connection of multiple sets of air pipes 12, the surface-mount resistors can be stably attracted to the bottom of the contactor 11. As the negative pressure passes through the collection column 13, the air pressure drives the rotating rod 15 connected to the impeller 18 to generate rotational power. During the continuous rotation, the permanent magnet 16 at the top of the rotating rod 15 will continuously generate ionization in the coil 17, thereby realizing wind power generation. The generated electricity is collected into the storage battery 8 through electrical connection. The storage battery 8 can then power the detector body 29, thereby realizing energy reuse and saving production costs.

[0036] Please see the appendix Figure 4 -Appendix Figure 5A one-way valve is provided at the bottom of the collection column 13. The one-way valve facilitates the disassembly and assembly of the air pipe 12 when replacing the suction plate 9. The delivery pipe 19 is fixedly connected to the output end of the negative pressure unit body 7. The negative pressure can pass through the inside of the collection column 13 through the delivery pipe 19.

[0037] Please see the appendix Figure 8 The battery 8 is electrically connected to the coil 17, which is made of copper.

[0038] The bearing block 6 is threaded to the outer wall of the first lead screw 21. Through the connection with the first lead screw 21, the bearing block 6 can achieve lateral displacement.

[0039] Please see the appendix Figure 3 Appendix Figure 4 Appendix Figure 7 The quick-release assembly includes a positioning plate 24, which is fixedly connected to one side of the quick-release block 10. An adjusting block 25 is rotatably connected to one side of the positioning plate 24. A locking rod 26 is fixedly connected to the bottom of the adjusting block 25. A bolt 27 is threadedly connected to one side of the positioning plate 24.

[0040] Since different surface mount resistors have different sizes, when the suction plate 9 needs to be replaced, the bolt 27 can be removed by threading to release the position limit of the adjusting block 25 and change the position of the adjusting block 25, so that the quick release block 10 and the docking block 30 can slide off. During the sliding off process, the air tube 12 at the one-way valve connection can be removed and a new air tube 12 and suction plate 9 can be inserted to complete the overall replacement process.

[0041] The locking rod 26 is slidably connected to both sides of the mating block 30. When the locking rod 26 slides to both sides of the mating block 30, the locking is completed. The locking rod 26 is always in the connection position of the mating block 30 by the fixing of the bolt 27. The bolt 27 is slidably connected to the top of the adjusting block 25.

[0042] Please see the appendix Figure 2 -Appendix Figure 3 The power assembly includes a first motor 31, which is fixedly connected to the top of the displacement rod 5. The output end of the first motor 31 is fixedly connected to a first bevel gear 20. The inner wall of the displacement rod 5 is rotatably connected to a first lead screw 21. A second bevel gear 32 is fixedly connected to one side of the outer wall of the first lead screw 21. A second motor 22 is fixedly connected to one side of the protective plate 1. The output end of the second motor 22 is fixedly connected to a second lead screw 23.

[0043] The first bevel gear 20 and the second bevel gear 32 are meshed together. Through the meshing connection between the first bevel gear 20 and the second bevel gear 32, the power of the first motor 31 can be transferred downward. The displacement rod 5 is threaded to the outer wall of the second lead screw 23. Through the threaded connection with the second lead screw 23, the displacement angle of the displacement rod 5 at the top of the protective plate 1 can be changed, thereby achieving the effect of precise positioning and facilitating the positioning operation of the staff.

[0044] Please see the appendix Figure 1 The detection assembly includes a placement platform 28, which is fixedly connected to the inner wall of the protective plate 1. A detector body 29 is installed on the top of the placement platform 28, and the battery 8 is electrically connected to the detector body 29.

[0045] The electricity collected in the storage battery 8 can provide continuous power to the detector body 29, thus eliminating the need to supply power to the detector body 29 separately. When the voltage is appropriate, the storage battery 8 can participate in the power supply of part of the first conveyor belt 2 and the second conveyor belt 4.
