Description

Technical Field

[0001] The present invention relates to the technical field of PCB board turning, and more specifically, to a turning machine for PCB board processing. Background Art

[0002] A PCB board is a basic component used to support and connect various electronic components in an electronic device. It realizes electrical connection by printing conductive lines on an insulating substrate, thus replacing the traditional point-to-point wiring method. PCB boards can be divided into single-layer, double-layer or multi-layer boards. In the existing PCB board processing, a turning machine is required to turn the PCB board over for processing the other side.

[0003] When the existing turning machine for PCB board processing is in use, the PCB board is conveyed into the turning machine through a conveyor belt, and the PCB board is clamped and fixed by a fixing device inside the turning machine. Then, the turning motor is started to turn the fixed PCB board by 180°. After the turning is completed, it is connected to another conveyor belt and conveyed to the next process for processing through the conveyor belt. At the same time, the turning motor needs to be started again to drive the fixing device to reset, so as to prepare for the turning of the next PCB board.

[0004] In actual use of the prior art, when the above turning machine completes the turning work, the turning machine needs to reset the turning device to the initial position before the turning operation of the next PCB board can be carried out, which increases the downtime of the equipment and reduces its production efficiency. At the same time, dust or other impurities are likely to adhere to the surface of the PCB board during the conveying process, affecting the quality of the subsequent process.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a turning machine for PCB board processing. Summary of the Invention

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 cooperate with the fixing plate for quick reset to prepare for the processing of the next PCB board.

[0010] As a further improvement of the present invention, the positioning and turnover component further includes a turnover motor fixedly installed inside the turnover groove. The output shaft end of the turnover motor is fixedly connected to a turnover rod through a coupling. A rotating plate is fixedly connected to the outer surface of the turnover rod. One end of the turnover rod is connected to the cross turnover plate. The mutual cooperation of the turnover motor and the turnover rod can drive the rotating plate and the cross turnover plate to perform turnover work, so as to achieve fast and stable turnover work.

[0011] As a further improvement of the present invention, the outer surface of the rotating plate is connected to the side surface of the cross flipping plate. Inside the rotating plate, a plurality of dust removal channels are opened near the inside of the plurality of fixing grooves. An air outlet that coincides with the dust removal channels is opened inside the dust removal box. The dust removal channels coincide with the air outlet inside the dust removal box, so that cold air can blow through the dust removal channels into the PCB board in the fixing groove to remove dust and fine particles on its surface, improving the dust removal effect.

[0012] As a further improvement of the present invention, a cooler is connected to the inner side wall of the dust removal box near the inside of the flipping groove. One end of the cooler is connected to a connecting pipe, and one end of the connecting pipe communicates with the inside of the dust removal box. A recovery groove is opened inside the flipping machine body, and a recovery box is clamped inside the recovery groove, thereby providing a cold source for the dust removal process and improving the efficiency of cold air transmission. At the same time, through the mutual cooperation of the recovery groove and the recovery box, it is ensured that the dust and impurities blown up during the dust removal process will be collected in the recovery box, avoiding secondary pollution and keeping the working environment clean.

[0017] Compared with the prior art, the advantages of the present invention are: In this solution, the PCB board is transported to the fixed groove in the cross flip plate by the second conveyor belt, and the magnetic field with the same polarity as the magnetic block is generated by starting the electromagnet. The corresponding fixing plate is driven by multiple magnetic blocks through the telescopic rod and the reset spring to fix the PCB board.

Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0021] Please refer to Figures 1-9 , a flap machine for PCB board processing, including a flap machine body 1, a positioning and flipping assembly 2, and a wireless power supply and dust removal assembly 3. A second conveyor belt 107 is installed on the left side surface of the flap machine body 1, a first conveyor belt 101 is installed in the inner cavity of the right side surface of the flap machine body 1, a PCB board 102 is installed on the upper surfaces of the first conveyor belt 101 and the second conveyor belt 107, and a flipping groove 103 is opened inside the flap machine body 1.

[0022] Specifically, the positioning and flipping component 2 is installed inside the flipping slot 103. Inside the cavity of the flipping slot 103, a cross-shaped flipping plate 201 is installed. Inside the cross-shaped flipping plate 201, a plurality of fixing slots 202 are provided. Inside the fixing slots 202, fixing plates 211 are installed. The positioning and flipping component 2 includes a plurality of telescopic rods 204 fixedly installed on the upper surface of the inner cavity of the fixing slots 202. One end of the telescopic rods 204 is connected to the fixing plate 211. Near the bottom of the inner cavity of the fixing slots 202 and close to the fixing plate 211, a silica gel pad 206 is installed. The silica gel pad 206 is made of silica gel material. The silica gel pad 206 is a gasket or liner made of silicone rubber material, with good elasticity and heat resistance. When the PCB board 102 is placed in the fixing slot 202, the silica gel pad 206 can absorb the impact force and prevent the PCB board 102 from being damaged due to direct contact with the hard surface. The silica gel pad 206 can be replaced by a polyurethane pad and a rubber pad. At the bottom of the fixing plate 211, a protective pad 207 is fixedly connected. 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 damages during the clamping process. The protective pad 207 can be replaced by a nylon fiber pad, a fluororubber pad, and a foam pad.

[0023] A return spring 205 is sleeved and connected on the outer surface of the telescopic rod 204. One end of the return spring 205 is connected to the fixing plate 211, and the other end is connected to the top wall of the inner cavity of the fixing slot 202. The positioning and flipping component 2 further includes a flipping motor 208 fixedly installed inside the flipping slot 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-shaped flipping plate 201. An alarm lamp 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. A plurality of support legs 104 are fixedly installed at the bottom of the flipping machine body 1. A friction pad is fixedly connected to the bottom of the support legs 104.

[0024] Furthermore, the speed of the conveyor belt two 107 gradually decreases, enabling the PCB board 102 to be smoothly parked on the fixing slot 202. The bottom of the first PCB board 102 abuts against the silica gel pad 206 to achieve preliminary positioning. Then, the electromagnet 3054 is activated to generate the same magnetic field as the plurality of magnetic blocks 203, prompting the plurality of magnetic blocks 203 to drive the fixing plate 211 to move downward. When the fixing plate 211 moves, it will drive the return spring 205 and the telescopic rod 204 to move, ensuring that the plurality of fixing plates 211 fix the four corners of the first PCB board 102. Embodiment

[0025] Refer to Figures 1-9, which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and the wireless power supply dust removal component 3 is installed inside the flipping groove 103.

[0026] Specifically, a dust removal box 301 is fixedly connected inside the flipping groove 103. A filter 304 is fixedly connected inside the connecting pipe 303. The filter 304 is used to remove moisture, oil stains, and other tiny particulate matters in the cold air to ensure the purity of the output gas, prevent condensed water droplets from dripping onto the PCB board 102, and avoid short circuits or other electrical faults caused by moisture. The cold air can not only effectively remove dust but also reduce the electrostatic adsorption phenomenon, further improving the dust removal effect and ensuring the cleanliness of the surface of the PCB board 102. The filter 304 can be replaced with a high-efficiency air filter or an activated carbon filter.

[0027] An electromagnetic induction power supply module 307 is fixedly connected inside the dust removal box 301. A wireless power supply component 305 is installed inside the fixing groove 202. The wireless power supply component 305 includes an electromagnet 3054 fixedly installed inside the fixing groove 202. A magnetic block 203 is installed inside the fixing plate 211. The electromagnet 3054 is magnetically connected to the magnetic block 203. 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 in the entire wireless power supply system, usually a battery or an energy storage device, which is responsible for providing the required electrical energy for other components. The power supply 3051 provides stable direct current for the wireless charging module 3052, the wireless communication module 3053, and the electromagnet 3054 to ensure the normal operation of these structures. The wireless charging module 3052 is a device used to receive electrical energy from the electromagnetic induction power supply module 307 (such as a transmitting coil) and convert it into available direct current. The wireless charging module 3052 receives energy in the alternating magnetic field through electromagnetic induction and converts the alternating current into direct current through a rectifying circuit for supply to other components. By using the wireless charging module 3052, the need for physical connection lines is reduced, the flexibility and reliability of the device are improved, and the wiring complexity and maintenance cost are reduced.

[0028] Inside the fixed slot 202, near the connection with the wireless charging module 3052, there is a wireless communication module 3053. The wireless communication module 3053 is a device for realizing data transmission and remote monitoring, usually based on Wi-Fi or other wireless communication protocols. The wireless communication module 3053 is responsible for data exchange with other devices or control systems; The electromagnetic induction power supply module 307 is a device for wireless power supply using the principle of electromagnetic induction. It usually 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, an induced electromotive force is generated inside it, forming an electric current to provide power for each component within the wireless power supply component 305, thus eliminating the need for physical connection wires, improving the safety and convenience of the device, and reducing the risk of failures caused by wire aging or short circuits.

[0029] The electromagnet 3054 is a device that generates a magnetic field through an electric current, usually composed of a coil and an iron core. When an electric current passes through the coil, a strong magnetic field is generated. The electromagnet 3054 controls the generated magnetic field to attract or repel the magnetic block 203, thereby driving the fixed plate 211 to move up and down, realizing the clamping and release of 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 fixed plate 211, usually made of a strong magnetic material (such as neodymium iron boron). It is used in cooperation with the electromagnet 3054 to achieve the up and down movement of the fixed plate 211 through magnetic interaction. When the electromagnet 3054 is powered on, the generated magnetic field will attract or repel the magnetic block 203, thereby causing the fixed plate 211 to move up and down, realizing the clamping and release of the PCB board 102.

[0030] The outer surface of the rotating plate 210 is connected to the side surface of the cross flipping plate 201. Inside the rotating plate 210, near the inside of multiple fixed slots 202, there are multiple dust removal channels 306 opened. Inside the dust removal box 301, there is an air outlet 309 that coincides with the dust removal channels 306. Inside the flipping slot 103, near the inner side wall of the dust removal box 301, there is a refrigerator 302 connected. One end of the refrigerator 302 is connected to a connecting pipe 303. One end of the connecting pipe 303 is connected to the inside of the dust removal box 301. Inside the flipping machine body 1, there is a recycling slot, and a recycling box 308 is snap-fitted inside the recycling slot. The refrigerator 302 is a device for generating cold air. The cold air generated by the refrigerator 302 is transported into 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 channels 306 to remove dust and other fine particles.

[0031] Further, the start electromagnet 3054 generates the same magnetic field as that of the multiple magnetic blocks 203, prompting the multiple magnetic blocks 203 to drive the fixing plate 211 to move downward. 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 started, and the cooler 302 starts to work, generating cold air. The cold air generated by the cooler 302 is continuously input into the dust removal box 301 through the connecting pipe 303. The flipping motor 208 is started to drive the flipping rod 209, the rotating plate 210 and the cross flipping plate 201 to rotate until they rotate to 90°, so that the dust removal channel 306 in the rotating plate 210 coincides with the air outlet 309 in the dust removal box 301. The cold air stored in the dust removal box 301 is blown out through the air outlet 309, and the cold air blows up the dust and fine particles on the surface of the PCB board 102. When the dust removal channel 306 coincides with the air outlet 309, an alternating magnetic field will be generated in the internal current of the electromagnetic induction power supply module 307. The receiving part in the wireless power supply 305 senses the alternating magnetic field and generates an induced electromotive force inside it. The induced current is converted into direct current through the rectifying circuit and supplied to each component in the wireless power supply 305, so as to realize the continuous processing of the PCB board 102 and improve its working efficiency.

[0032] The working principle of the present invention: 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 to work by operating the controller 105. The second conveyor belt 107 conveys 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 parked on the fixing groove 202. The bottom of the first PCB board 102 abuts against the silica gel pad 206 to achieve preliminary positioning. The silica gel pad 206 plays a role in buffering and anti-sliding. Then, the start electromagnet 3054 generates the same magnetic field as that of the multiple magnetic blocks 203, prompting the multiple magnetic blocks 203 to drive the fixing plate 211 to move downward. 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, so as to ensure 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 and avoid scratching or damaging the surface of the PCB board 102 during the fixing process. At the same time, the cooler 302 is started, and the cooler 302 starts to work, generating cold air. The cold air generated by the cooler 302 is continuously input into the dust removal 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 to prevent condensed water from dripping on the PCB board 102 and causing damage.

[0033] Subsequently, start the flipping motor 208 to drive the flipping rod 209 to rotate. When the flipping rod 209 rotates, it will drive the rotating plate 210 and the cross flipping plate 201 to rotate, so that they rotate to 90°, thereby making the dust removal channel 306 in the rotating plate 210 coincide with the air outlet 309 in the dust removal box 301. The cold air stored in the dust removal box 301 is blown out through the air outlet 309 and blown towards the first PCB board 102 being fixed through the dust removal channel 306. The cold air blows up the dust and fine particles on the surface of the PCB board 102 and flows into the recovery box 308 corresponding to the dust removal box 301 for storage. At the same time, when the cross flipping plate 201 rotates, another fixing groove 202 corresponds to the second conveyor belt 107, and the second PCB board 102 to be flipped on the second conveyor belt 107 is conveyed into the fixing groove 202. Then, start the corresponding electromagnet 3054 in this fixing groove 202, and multiple fixing plates 211 fix the four corners of the second PCB board 102 through the mutual cooperation of the magnetic blocks 203, telescopic rods 204 and return springs 205.

[0034] When the dust removal channel 306 coincides with the air outlet 309, an alternating magnetic field will be generated by the current inside the electromagnetic induction power supply module 307. The receiving and induction coil in the wireless power supply 305 senses the alternating magnetic field and generates an induced electromotive force inside it to form an alternating current. The induced current is converted into direct current through the rectification circuit and supplied to each component in the wireless power supply 305. The direct current first charges the power supply 3051 to ensure that it has enough power to support subsequent operations, and then continues to supply power to 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 for dust removal can dissipate heat from the wireless power supply 305 and the electromagnetic induction power supply module 307 during wireless charging, blowing their heat to the outside to ensure the stable operation of the device.

[0035] After the dust removal of the PCB board 102 is completed, start the flipping motor 208 to perform a 90° flip again, so that the first PCB board 102 corresponds to the conveyor belt 101. Then start the electromagnet 3054 in this fixing slot 202 to generate a magnetic field opposite to that of the magnetic block 203. The magnetic block 203 is repelled under the action of the opposite magnetic field, driving the fixing plate 211 to move upward, releasing the fixation of the first PCB board 102, and enabling the first PCB board 102 to be conveyed to the next process for processing through the conveyor belt 101. At the same time, while the second PCB board 102 is being dusted again, the internal wireless power supply component 305 can be wirelessly charged and cooled simultaneously. At the same time, the conveyor belt 101 can convey the third PCB board 102 into the fixing slot 202 to fix the fixing plate 211 in the fixing slot 202. At the same time, the second PCB board 102 is fixed in the fixing slot 202. After the dust removal of the third PCB board 102 is completed, start the flipping motor 208 to perform a 90° flip again, and so on. The continuous processing of the PCB board 102 can be realized, thereby improving its working efficiency.
