Description

Technical Field

[0001] This invention relates to the field of PCB board flipping technology, and more specifically, to a PCB board flipping machine. Background Technology

[0002] A PCB (Printed Circuit Board) is a fundamental component in electronic devices used to support and connect various electronic components. It achieves electrical connections by printing conductive lines on an insulating substrate, thus replacing the traditional point-to-point wiring method. PCBs can be single-layer, double-layer, or multi-layer boards. Current PCB manufacturing processes require the use of a flipping machine to turn the PCB over for processing on the other side.

[0003] In existing PCB board processing flipping machines, PCB boards are transported into the machine via a conveyor belt and clamped and fixed by a fixing device inside the machine. Then, the flipping motor is started to flip the fixed PCB board 180°. After the flipping is completed, it is connected to another conveyor belt and transported to the next process for processing. At the same time, the flipping motor needs to be started again to drive the fixing device to reset, in preparation for the flipping of the next PCB board.

[0004] In practical use, the existing technology requires the flipping machine to reset the flipping device to its initial position after completing the flipping operation before it can perform the flipping operation of the next PCB board. This increases the downtime of the equipment and reduces its production efficiency. At the same time, dust or other impurities are easily attached to the surface of the PCB board during the transportation process, which affects the quality of subsequent processes.

[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a PCB board flipping machine. Summary of the Invention

[0006] The purpose of this invention is to provide a PCB board flipping machine to solve the above-mentioned problems.

[0007] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0008] A PCB board processing flipping machine includes a flipping machine body, a positioning and flipping component, and a wireless power supply dust removal component. A second conveyor belt is installed on the left side of the flipping machine body, and a first conveyor belt is installed inside the right side cavity of the flipping machine body. PCB boards are mounted on the upper surfaces of the first and second conveyor belts. A flipping groove is formed inside the flipping machine body. The positioning and flipping component is installed inside the flipping groove. A cross-shaped flipping plate is installed inside the flipping groove. Multiple fixing grooves are formed inside the cross-shaped flipping plate, and fixing plates are installed inside the fixing grooves. The wireless power supply dust removal component is installed inside the flipping groove. A dust removal box is fixedly connected inside the flipping groove. A filter is fixedly connected inside the connecting pipe. An electromagnetic induction power supply module is fixedly connected inside the dust removal box.

[0009] As a further improvement of the present invention, the positioning and flipping assembly includes multiple telescopic rods fixedly installed on the upper surface of the inner cavity of the fixing groove. One end of each telescopic rod is connected to a fixing plate. A silicone pad is installed near the bottom of the fixing plate in the inner cavity of the fixing groove. The silicone pad is made of silicone material. A protective pad is fixedly connected to the bottom of the fixing plate. The protective pad is made of elastic material. The telescopic rods can support the fixing plate, ensuring that the PCB board is fixedly clamped by the fixing plate. The cooperation between the silicone pad and the protective pad can prevent scratches or other physical damage to the surface of the PCB board during the fixing process, ensuring the quality of the PCB board.

[0010] As a further improvement of the present invention, a return spring is sleeved and connected to the outer surface of the telescopic rod. One end of the return spring is connected to the fixing plate, and the other end is connected to the top wall of the inner cavity of the fixing groove. The return spring can work with the fixing plate to quickly reset, so as to prepare for the processing of the next PCB board.

[0011] As a further improvement of the present invention, the positioning and flipping assembly further includes a flipping motor fixedly installed inside the flipping groove. The output shaft end of the flipping motor is fixedly connected to a flipping rod through a coupling. A rotating plate is fixedly connected to the outer surface of the flipping rod. One end of the flipping rod is connected to the cross flipping plate. Through the cooperation of the flipping motor and the flipping rod, the rotating plate and the cross flipping plate can be driven to flip, thereby achieving fast and stable flipping operation.

[0012] As a further improvement of the present invention, the outer surface of the rotating plate is connected to the side of the cross-shaped flipping plate, and multiple dust removal channels are opened inside the rotating plate near the multiple fixed slots. The dust removal box has an air outlet that matches the dust removal channels. The dust removal channels match the air outlet in the dust removal box, so that cold air can be blown through the dust removal channels to the PCB board in the fixed slots to remove dust and fine particles from its surface and improve the dust removal effect.

[0013] As a further improvement of the present invention, a cooler is connected to the inner side wall of the dust collection box near the interior of the flipping trough. One end of the cooler is connected to a connecting pipe, and one end of the connecting pipe is connected to the interior of the dust collection box. A recycling trough is opened inside the flipping machine body, and a recycling box is snapped into the interior of the recycling trough, thereby providing a cold source for the dust removal process and improving the efficiency of cold air transmission. At the same time, the cooperation between the recycling trough and the recycling box ensures that the dust and impurities blown up during the dust removal process are collected in the recycling box, avoiding secondary pollution and maintaining a clean working environment.

[0014] As a further improvement of the present invention, the wireless power supply component includes an electromagnet fixedly installed inside the fixing slot, and a magnetic block is installed inside the fixing plate. The electromagnet and the magnetic block are magnetically connected. Through the magnetic connection between the electromagnet and the magnetic block, the fixing plate can fix the PCB board.

[0015] As a further improvement of the present invention, the wireless power supply component includes a power supply and a wireless charging module fixedly installed on the upper surface of the electromagnet. A wireless communication module is connected inside the fixing slot near the wireless charging module. Through the coordinated work of the power supply, the wireless charging module and the wireless communication module, efficient wireless power supply is achieved.

[0016] As a further improvement of the present invention, an alarm light is fixedly connected to the upper surface of the flipping machine body, and a controller is installed on the outer surface of the flipping machine body. The alarm light can provide an important safety warning function, ensuring that operators can detect and deal with equipment abnormalities in a timely manner, thereby improving the safety and reliability of the equipment. The controller can precisely control and monitor the device.

[0017] As a further improvement of the present invention, a plurality of support legs are fixedly installed at the bottom of the flipping machine body, and friction pads are fixedly connected to the bottom of the support legs so as to support the flipping machine body.

[0018] Compared with the prior art, the advantages of this invention are:

[0019] In this scheme, the PCB board is conveyed to the fixing slot in the cross-shaped flip plate by the second conveyor belt, and a magnetic field with the same pole as the magnetic block is generated by activating the electromagnet. Multiple magnetic blocks are used to drive the corresponding fixing plate to fix the PCB board through the telescopic rod and the return spring. At the same time, the silicone pad and the protective pad can protect the surface of the PCB board and avoid scratches or damage to the PCB board surface during the fixing process; (2) By activating the cooler, cold air is generated. The cold air is transported to the dust removal box through the connecting pipe. When it flows through the connecting pipe, water vapor and other impurities are removed by the internal filter to prevent condensate from dripping onto the PCB board and causing damage. At the same time, the rotating motor is started to drive the rotating rod, so that the rotating plate and the cross rotating plate rotate to 90°. The dust removal channel in the rotating plate matches the air outlet of the dust removal box, so that the cold air in the dust removal box is blown to the PCB board surface through the air outlet and the dust removal channel, effectively removing dust and fine particles. The dust and impurities after dust removal are collected in the recycling box, avoiding secondary pollution and maintaining the cleanliness of the working environment. At the same time, the cold air can also reduce the electrostatic adsorption phenomenon, further improving the cleanliness and quality of the PCB board; (3) When the electromagnetic induction power supply module senses the alternating magnetic field, it generates an induced electromotive force inside it, which is converted by the rectifier circuit. By switching to DC power, the power supply, wireless charging module, wireless communication module and electromagnet are supplied, thereby ensuring that each component can obtain a stable power supply, improving the reliability of the system, and enabling the wireless power supply component to be powered by the electromagnetic induction power supply module without the need for physical connection wires, simplifying the system structure and reducing maintenance difficulty; (4) At the same time, when the cold air flows through the wireless power supply component and the electromagnetic induction power supply module, it can carry away the heat generated during power supply, lower the temperature, thereby reducing the failure rate of the wireless power supply component and the electromagnetic induction power supply module due to overheating, improving its stability, ensuring its normal operation, so that the cold air can not only be used for dust removal, It can also dissipate heat from the wireless power supply components and electromagnetic induction power supply modules that are wirelessly charging, thus reducing manual intervention; (5) Through the cooperation of the cross flip plate and the electromagnets, magnetic blocks and fixing plates installed separately in the four fixing slots, multiple PCB boards can be transported, fixed, dusted and transported to the next process at the same time, so that multiple PCB boards can be processed at the same time to achieve continuous flipping work, thereby reducing the downtime of the equipment, improving production efficiency, and avoiding the need to reset the traditional flipping machine body after completing the flipping work of one PCB board before performing the flipping work of the next PCB board.

Detailed Implementation

[0033] The technical solutions in 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0034] Please see Figures 1-9 A PCB board processing flipping machine includes a flipping machine body 1, a positioning and flipping component 2, and a wireless power supply dust removal component 3. A second conveyor belt 107 is installed on the left side of the flipping machine body 1, and a first conveyor belt 101 is installed in the inner cavity of the right side of the flipping machine body 1. PCB boards 102 are installed on the upper surfaces of the first conveyor belt 101 and the second conveyor belt 107. A flipping groove 103 is opened inside the flipping machine body 1.

[0035] Specifically, the positioning and flipping assembly 2 is installed inside the flipping groove 103. A cross-shaped flipping plate 201 is installed inside the inner cavity of the flipping groove 103. Multiple fixing grooves 202 are formed inside the cross-shaped flipping plate 201. A fixing plate 211 is installed inside each fixing groove 202. The positioning and flipping assembly 2 includes multiple telescopic rods 204 fixedly installed on the upper surface of the inner cavity of the fixing groove 202. One end of each telescopic rod 204 is connected to the fixing plate 211. A silicone pad 206 is installed near the bottom of the fixing plate 211 inside the inner cavity of the fixing groove 202. The silicone pad 206 is made of silicone material and is a gasket or liner made of silicone rubber. With good elasticity and temperature resistance, the silicone pad 206 can absorb impact when the PCB board 102 is placed in the fixing groove 202, preventing the PCB board 102 from being damaged due to direct contact with hard surfaces. The silicone pad 206 can be replaced by a polyurethane pad or a rubber pad. A protective pad 207 is fixedly connected to the bottom of the fixing plate 211. The protective pad 207 is made of elastic material. The protective pad 207 is a gasket made of elastic material. The protective pad 207 can protect the surface of the PCB board 102 from scratches or other mechanical damage during clamping. The protective pad 207 can be replaced by a nylon fiber pad, a fluororubber pad, or a foam pad.

[0036] A return spring 205 is sleeved on the outer surface of the telescopic rod 204. One end of the return spring 205 is connected to the fixed plate 211, and the other end is connected to the top wall of the inner cavity of the fixed groove 202. The positioning and flipping assembly 2 also includes a flipping motor 208 fixedly installed inside the flipping groove 103. The output shaft end of the flipping motor 208 is fixedly connected to a flipping rod 209 through a coupling. A rotating plate 210 is fixedly connected to the outer surface of the flipping rod 209. One end of the flipping rod 209 is connected to the cross flipping plate 201. An alarm light 106 is fixedly connected to the upper surface of the flipping machine body 1. A controller 105 is installed on the outer surface of the flipping machine body 1. Multiple support legs 104 are fixedly installed at the bottom of the flipping machine body 1. Friction pads are fixedly connected to the bottom of the support legs 104.

[0037] Furthermore, the speed of the second conveyor belt 107 gradually decreases, allowing the PCB board 102 to be smoothly placed on the fixing slot 202. The bottom of the first PCB board 102 abuts against the silicone pad 206, achieving initial positioning. Then, the electromagnet 3054 is activated to generate a magnetic field identical to that of the multiple magnetic blocks 203, causing the multiple magnetic blocks 203 to move the fixing plate 211 downwards. When the fixing plate 211 moves, it will drive the reset spring 205 and the telescopic rod 204 to move, ensuring that the multiple fixing plates 211 fix the four corners of the first PCB board 102. Example

[0038] Reference Figures 1-9 This is the second embodiment of the present invention, which is based on the previous embodiment, in which the wirelessly powered dust removal component 3 is installed inside the flip-up slot 103.

[0039] Specifically, the dust collection box 301 is fixedly connected inside the flip-top slot 103, and a filter 304 is fixedly connected inside the connecting pipe 303. The filter 304 is used to remove moisture, oil and other small particles from the air conditioner to ensure the purity of the output gas. It can prevent condensate from dripping onto the PCB board 102 and avoid short circuits or other electrical faults caused by moisture. The air conditioner can not only effectively remove dust, but also reduce electrostatic adsorption, further improving the dust removal effect and ensuring the cleanliness of the PCB board 102 surface. The filter 304 can be replaced by a high-efficiency air filter or an activated carbon filter.

[0040] An electromagnetic induction power supply module 307 is fixedly connected inside the dust collection box 301. A wireless power supply component 305 is installed inside the fixing slot 202. The wireless power supply component 305 includes an electromagnet 3054 fixedly installed inside the fixing slot 202. A magnetic block 203 is installed inside the fixing plate 211. The electromagnet 3054 and the magnetic block 203 are magnetically connected. The wireless power supply component 305 includes a power supply 3051 and a wireless charging module 3052 fixedly installed on the upper surface of the electromagnet 3054. The power supply 3051 is the power source of the entire wireless power supply system, usually a battery or energy storage device. It is responsible for providing the required power to other components. 1. Provides stable DC power to the wireless charging module 3052, wireless communication module 3053, and electromagnet 3054 to ensure that these structures can function properly. The wireless charging module 3052 is a device for receiving electrical energy from the electromagnetic induction power supply module 307 (such as a transmitting coil) and converting it into usable DC power. The wireless charging module 3052 receives energy from an alternating magnetic field through electromagnetic induction and converts the AC power into DC power through a rectifier circuit to supply other components. The wireless charging module 3052 reduces the need for physical connection cables, improves the flexibility and reliability of the device, and reduces wiring complexity and maintenance costs.

[0041] Inside the fixed slot 202, near the wireless charging module 3052, is a wireless communication module 3053. The wireless communication module 3053 is a device for data transmission and remote monitoring, typically based on Wi-Fi or other wireless communication protocols. The wireless communication module 3053 is responsible for exchanging data with other devices or control systems. The electromagnetic induction power supply module 307 is a device that uses the principle of electromagnetic induction to provide wireless power. It typically includes a transmitting coil and a receiving coil. The electromagnetic induction power supply module 307 generates an alternating magnetic field through the transmitting coil. After the receiving coil senses this magnetic field, it generates an induced electromotive force inside, forming a current to provide power to the various components within the wireless power supply module 305. This eliminates the need for physical connection wires, improves the safety and convenience of the device, and reduces the risk of failure due to aging or short circuits in the wiring.

[0042] An electromagnet 3054 is a device that generates a magnetic field through an electric current, typically consisting of a coil and an iron core. When current passes through the coil, a strong magnetic field is generated. The electromagnet 3054 attracts or repels the magnetic block 203 by controlling the magnetic field it generates, thereby moving the fixing plate 211 up and down to clamp and release the PCB board 102, ensuring that the PCB board 102 does not move or shake during the flipping process. The magnetic block 203 is a magnetic material installed inside the fixing plate 211, usually made of a strong magnetic material (such as neodymium iron boron). It works in conjunction with the electromagnet 3054 to achieve the up and down movement of the fixing plate 211 through magnetic interaction. When the electromagnet 3054 is energized, the generated magnetic field attracts or repels the magnetic block 203, thereby moving the fixing plate 211 up and down to clamp and release the PCB board 102.

[0043] The outer surface of the rotating plate 210 is connected to the side of the cross-shaped flip plate 201. The interior of the rotating plate 210 is provided with multiple dust removal channels 306 near the interior of multiple fixed slots 202. The interior of the dust removal box 301 is provided with an air outlet 309 that matches the dust removal channels 306. The interior of the flip slot 103 is connected to the inner side wall of the dust removal box 301 and a cooler 302 is connected to it. One end of the cooler 302 is connected to a connecting pipe 303, and one end of the connecting pipe 303 is connected to the interior of the dust removal box 301. The interior of the flip machine body 1 is provided with a recycling trough, and a recycling box 308 is snapped into the interior of the recycling trough. The cooler 302 is a device for generating cold air. The cold air generated by the cooler 302 is transported to the dust removal box 301 through the connecting pipe 303, and then blown onto the surface of the PCB board 102 through the dust removal channel 306 to remove dust and other small particles.

[0044] Furthermore, the electromagnet 3054 is activated to generate a magnetic field identical to that of the multiple magnetic blocks 203, causing the multiple magnetic blocks 203 to move the fixing plate 211 downwards. When the fixing plate 211 moves, it will drive the return spring 205 and the telescopic rod 204 to move, ensuring that the multiple fixing plates 211 fix the four corners of the first PCB board 102. At the same time, the cooler 302 is activated and starts working, generating cold air. The cold air generated by the cooler 302 is continuously input into the dust collection box 301 through the connecting pipe 303. The flip motor 208 is activated to drive the flip rod 209, the rotating plate 210 and the cross flip plate 201 to rotate, making them rotate 90°. This allows the dust removal channel 306 inside the rotating plate 210 to match the air outlet 309 inside the dust removal box 301. The cold air stored in the dust removal box 301 is blown out through the air outlet 309. The cold air blows up the dust and fine particles on the surface of the PCB board 102. When the dust removal channel 306 matches the air outlet 309, the current inside the electromagnetic induction power supply module 307 will generate an alternating magnetic field. The receiver in the wireless power supply component 305 senses the alternating magnetic field and generates an induced electromotive force inside it. The induced current is converted into DC current through the rectifier circuit and supplied to the various components in the wireless power supply component 305, thereby enabling continuous processing of the PCB board 102 and improving its working efficiency.

[0045] The working principle of this invention is as follows: The PCB board 102 to be flipped is placed on the second conveyor belt 107. The first conveyor belt 101 and the second conveyor belt 107 are started by the operation controller 105. The second conveyor belt 107 transports the PCB board 102 towards the cross flipping plate 201. When the PCB board 102 reaches the fixing groove 202 of the cross flipping plate 201, the speed of the second conveyor belt 107 gradually decreases, so that the PCB board 102 can be stably stopped on the fixing groove 202. The bottom of the first PCB board 102 abuts against the silicone pad 206 to achieve initial positioning. The silicone pad 206 plays a role in buffering and anti-slip. Then, the electromagnet 3054 is activated to generate a magnetic field that is the same as that of multiple magnetic blocks 203, causing the multiple magnetic blocks 203 to drive the fixing plate 211 downward. When the fixing plate 211... When the device moves, it will drive the return spring 205 and the telescopic rod 204 to move, ensuring that the multiple fixing plates 211 fix the four corners of the first PCB board 102, thereby ensuring that the PCB board 102 will not move or shake during the flipping process. The protective pad 207 at the bottom of the fixing plate 211 can protect the surface of the first PCB board 102, avoiding scratches or damage to the surface of the PCB board 102 during the fixing process. At the same time, the cooler 302 is started and starts to work, generating cold air. The cold air generated by the cooler 302 is continuously input into the dust collection box 301 through the connecting pipe 303. When the cold air enters through the connecting pipe 303, it passes through the filter 304. The filter 304 removes the water vapor contained in the cold air, preventing condensation from dripping onto the PCB board 102 and causing damage.

[0046] Subsequently, the flipping motor 208 is activated, driving the flipping rod 209 to rotate. When the flipping rod 209 rotates, it drives the rotating plate 210 and the cross-shaped flipping plate 201 to rotate 90°. This aligns the dust removal channel 306 within the rotating plate 210 with the air outlet 309 within the dust collection box 301, allowing the cold air stored in the dust collection box 301 to be blown out through the air outlet 309 and then through the dust removal channel 306 towards the first PCB board 102 being fixed. The cold air blows up dust and fine particles from the surface of the PCB board 102, and... The cold air flows into the recycling bin 308 corresponding to the dust collection bin 301 for storage. At the same time, when its cross-shaped flip plate 201 rotates, another fixing slot 202 aligns with the second conveyor belt 107, so that the second PCB board 102 to be flipped on the second conveyor belt 107 is transported into the fixing slot 202. The corresponding electromagnet 3054 in this fixing slot 202 is activated again, causing multiple fixing plates 211 to fix the four corners of the second PCB board 102 through the cooperation of the magnetic block 203, the telescopic rod 204 and the return spring 205.

[0047] When the dust removal channel 306 matches the air outlet 309, the internal current of the electromagnetic induction power supply module 307 generates an alternating magnetic field. The receiver in the wireless power supply component 305 senses the alternating magnetic field and generates an induced electromotive force, forming an alternating current. The induced current is converted into direct current by the rectifier circuit and supplies power to the various components in the wireless power supply component 305. The direct current first charges the power supply 3051 to ensure it has enough power to support subsequent operations, and then continues to power the wireless charging module 3052, the wireless communication module 3053, and the electromagnet 3054 to ensure that these components can work normally. During the wireless charging process, the cold air from the dust removal can dissipate heat from the wireless power supply component 305 and the electromagnetic induction power supply module 307 that are wirelessly charging, blowing their heat to the outside to ensure stable operation of the equipment.

[0048] After the PCB board 102 has been dusted, the flipping motor 208 is started to flip it 90° again, aligning the first PCB board 102 with the conveyor belt 101. Then, the electromagnet 3054 in the fixing slot 202 is activated to generate a magnetic field opposite to that of the magnetic block 203. The magnetic block 203 is repelled by the opposite magnetic field, causing the fixing plate 211 to move upward, releasing the fixing of the first PCB board 102. This allows the first PCB board 102 to be transported to the next process via the conveyor belt 101 for processing. At the same time, the second PCB board 102... While performing dust removal again, the internal wireless power supply component 305 can be wirelessly charged and cooled simultaneously. At the same time, the conveyor belt 101 can transport the third PCB board 102 into the fixing slot 202, fixing the fixing plate 211 in the fixing slot 202. Meanwhile, the second PCB board 102 is fixed in the fixing slot 202. After the dust removal of the third PCB board 102 is completed, the flipping motor 208 is started again to flip it 90°. This process is repeated to achieve continuous processing of the PCB board 102, thereby improving its working efficiency.
