Description

Technical Field

[0001] The utility model relates to the field of printed circuit board manufacturing, and specifically relates to a loading device for the etching process of printed circuit boards. Background Art

[0002] The etching of printed circuit boards is a key process for manufacturing circuit boards. The main purpose is to remove the unnecessary copper layers on the copper clad laminate through chemical methods, thereby forming the conductive paths and patterns on the circuit board. Before etching the printed circuit board, pre-treatment such as laminating ultra-thin copper foil, making anti-plating patterns, electroplating copper, stripping photosensitive dry film, etc. is required for the printed circuit board.

[0003] In many existing circuit board manufacturing production lines, the etching process and the pre-treatment process of the circuit board are separated and non-continuous production line operations. This requires transferring the pre-treated circuit boards to the conveyor line of the etching equipment. Usually, a loading device is used to load the pre-treated circuit boards onto the conveyor line of the etching equipment. The existing loading devices usually use manipulators, which have complex structures, high costs, and also require a high degree of professionalism in debugging the manipulators. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a loading device for the etching process of printed circuit boards to solve the above technical problems.

[0005] According to one aspect of the utility model, a loading device for the etching process of printed circuit boards is provided, including:

[0006] A conveying part, the conveying part includes a plurality of rollers arranged in parallel;

[0007] A bearing table, the bearing table is arranged on the side of the conveying part and is lower than the rollers;

[0008] A loading member, the loading member is used to transfer the circuit board on the bearing table to the rollers;

[0009] A rotating shaft, the loading member is fixedly arranged on the rotating shaft;

[0010] A driving device, the driving device drives the rotating shaft to rotate so that the loading member transfers the circuit board on the bearing table to the rollers; and

[0011] An adsorption component, the adsorption component is used to adsorb and transfer the circuit board on the bearing table to the loading member.

[0012] The conveying part of the feeding device of the printed circuit board etching process of the utility model is installed at the inlet end of the conveying line of the etching equipment, and the roller can convey the circuit board to be etched to the etching equipment. Under the action of the adsorption component, the adsorption component can adsorb and transfer the circuit board on the carrier to the feeding piece, and then under the action of the driving device, the rotating shaft drives the feeding piece to flip, and the feeding piece can transfer the circuit board to be etched to the roller, and the rotating roller conveys the circuit board to be etched to the etching equipment for etching, and then under the action of the driving device, the rotating shaft drives the feeding piece to flip in the opposite direction, and the feeding piece flips to the end of the carrier. The component to be adsorbed transfers the next circuit board to the loading piece by adsorption. The loading device of the utility model can transfer the circuit board to be etched on the carrier table to the roller of the conveying part by driving the loading piece to flip and reverse direction and the adsorption cooperation of the adsorption component through the driving device. The structure is simple and the cost is low. It only needs to set the working mode of the driving device and the adsorption component in advance. The conveying part can be the conveying part of the etching equipment. A carrier can be placed on the carrier table, and the circuit boards to be etched are stacked horizontally on the carrier. The carrier full of circuit boards to be etched can be pushed to the carrier table by a trolley.

[0013] Preferably, the adsorption component includes a cylinder, a push plate and a vacuum suction cup, the push plate is arranged on the piston rod of the cylinder, the vacuum suction cup is arranged on the push plate, and the vacuum suction cup can adsorb and transfer the circuit board on the supporting platform to the loading piece.

[0014] Therefore, when the loading piece is flipped to the end of the supporting platform, the piston rod of the cylinder extends, and the push plate moves toward the circuit board on the supporting platform, and the push plate drives the vacuum suction cup to move toward the circuit board on the supporting platform. The vacuum suction cup forms negative pressure by exhausting air so that the vacuum suction cup is adsorbed on the circuit board, and then the piston rod of the cylinder retracts, and the push plate moves away from the supporting platform, and the push plate drives the vacuum suction cup to move away from the supporting platform, and the vacuum suction cup transfers the adsorbed circuit board to the loading piece, and then air is allowed to pass through the vacuum suction cup, the vacuum suction cup is separated from the circuit board, and the circuit board is completely transferred to the loading piece, and the loading piece can transfer the circuit board to be etched to the roller.

[0015] Preferably, it also includes a push rod component, which includes a push rod, a spring and a limiting ring. One end of the push rod is provided with a top portion, and the other end of the push rod is inserted into the push plate and can slide in the push plate. The limiting ring is sleeved on the other end of the push rod, and the spring is sleeved on the push rod. One end of the spring abuts against the push plate, and the other end of the spring abuts against the top portion.

[0016] When the spring is in a natural state, the distance from the top to the push plate is greater than the distance from the vacuum suction cup to the push plate.

[0017] Therefore, when the loading part is flipped to the end of the loading platform, the piston rod of the air cylinder extends, the push plate moves towards the circuit board on the loading platform, the push plate drives the vacuum suction cup and the ejector rod component to move towards the circuit board on the loading platform. Since the distance from the top to the push plate in the natural state is greater than the distance from the vacuum suction cup to the push plate, the top of the ejector rod will contact the circuit board first. As the push plate continues to move, the circuit board will press the top of the ejector rod, causing the ejector rod to slide in the push plate, and at the same time, the spring on the ejector rod is compressed. When the vacuum suction cup contacts the circuit board, the vacuum suction cup forms a negative pressure by pumping air, so that the vacuum suction cup adsorbs on the circuit board. Then, the piston rod of the air cylinder retracts, the push plate moves away from the loading platform, the push plate drives the vacuum suction cup to move away from the loading platform, and the vacuum suction cup transfers the adsorbed circuit board to the loading part. Then, air is introduced into the vacuum suction cup. Under the restoring force of the spring on the ejector rod, the top of the ejector rod will push the circuit board away from the vacuum suction cup, so as to separate the circuit board from the vacuum suction cup. The circuit board is completely transferred to the loading part, and the loading part can transfer the circuit board to be etched to the roller. The existence of the ejector rod component can ensure that when air is introduced into the vacuum suction cup, the circuit board and the vacuum suction cup can be completely separated, preventing unnecessary adsorption. The limit ring can prevent the ejector rod from disengaging from the push plate.

[0018] Preferably, the loading part includes two parallel loading rods, the two loading rods are fixedly arranged on the rotating shaft, the bottom end of the loading rod is hook-shaped, and the driving device can drive the two loading rods to be flipped onto the conveying part.

[0019] When the driving device drives the two loading rods to be flipped to the end of the loading platform, the adsorption component can adsorb and transfer the circuit board on the loading platform to the two loading rods.

[0020] Therefore, when the adsorption component adsorbs and transfers the circuit board on the loading platform to the two loading rods, since the bottom end of the loading rod is hook-shaped, the bottom end of the loading rod will hold up the circuit board upward, ensuring that the circuit board will not slip off the loading rod during the flipping process of the loading rod. When the two loading rods are flipped to the end of the loading platform to transfer the next circuit board, as long as the opening of the hook shape at the bottom of the loading rod is inclined upward towards the loading platform, under the action of the adsorption component, the vacuum suction cup can transfer the circuit board on the loading platform to the two loading rods.

[0021] Preferably, the four rollers close to the loading platform are all discontinuous. Each discontinuous roller includes three sub-rollers. There is a gap for accommodating the loading rod between two adjacent sub-rollers on the same roller. The driving device can drive the two loading rods to be flipped into the gap between two adjacent sub-rollers on the same roller.

[0022] Therefore, under the action of the driving device, the rotating shaft drives the two loading rods carrying the circuit boards to flip. The two loading rods can respectively flip into the gaps between adjacent sub-rollers on the four discontinuous rollers. In this way, under the combined action of the continuous roller and the four discontinuous rollers, the circuit board to be etched can be transported to the etching equipment for etching. The loading rod flipping into the gap between adjacent sub-rollers on the four discontinuous rollers can ensure that the circuit board is automatically transported into the etching equipment without affecting the normal rotation of the discontinuous rollers.

[0023] Preferably, the top end of the loading rod is provided with an inclined surface, and the free end of the bottom end of the loading rod is provided with a roller.

[0024] Therefore, the existence of the inclined surface can ensure that the circuit board carried on the loading rod can be smoothly transported onto the roller. In addition, when the adsorption component adsorbs and transfers the circuit board onto the loading rod, the existence of the roller can ensure that the bottom of the circuit board can be smoothly slid into the hook-shaped part at the bottom of the loading rod, and can also prevent the free end of the bottom end of the loading rod from scratching the circuit board.

[0025] Preferably, it further includes an L-shaped connecting rod. The driving device is a cylinder. One end of the L-shaped connecting rod is fixedly arranged on the rotating shaft, and the other end of the L-shaped connecting rod is hinged on the driving shaft of the driving device. The cylinder body of the driving device is hinged on the bearing platform.

[0026] Therefore, in this way, when the driving shaft of the driving device (cylinder) makes an extending action, the rotating shaft can be driven to rotate forward through the L-shaped connecting rod. The rotating shaft rotating forward can drive the loading part to flip to the end of the bearing platform. When the driving shaft of the driving device (cylinder) makes a retracting action, the rotating shaft can be driven to rotate reversely through the L-shaped connecting rod. The rotating shaft rotating reversely can drive the loading part to flip to the conveying part. Due to the cylinder body of the driving device being hinged on the bearing platform and the action of the L-shaped connecting rod, the linear motion of the driving shaft of the driving device (cylinder) can be converted into the circular motion of the rotating shaft.

[0027] Preferably, it further includes a conveyor belt. There are two parallel bosses arranged on the bearing platform, and the conveyor belt is arranged between the two bosses.

[0028] Therefore, a carrier can be placed on the conveyor belt, and multiple circuit boards to be etched are stacked horizontally on the carrier. When the adsorption component adsorbs and transfers one circuit board on the carrier, the conveyor belt can drive the carrier to displace a short distance towards the adsorption component to ensure that the adsorption component can still adsorb the circuit board on the carrier during the next action. As long as the working mode of the conveyor belt is set in advance, in addition, when the carrier is full of circuit boards, the weight will be very heavy. After the trolley pushes the carrier full of circuit boards onto the conveyor belt, under the conveying action of the conveyor belt, the carrier can be moved to a position close to the adsorption component and the loading part without manual pushing.

[0029] Preferably, it further includes a carrier for transporting the circuit board. The carrier is placed on the conveyor belt and located between two bosses, and the height of the conveyor belt is less than the height of the bosses.

[0030] Therefore, the loading part can transfer the circuit board on the carrier to the roller of the conveying part. After the adsorption component adsorbs and transfers one circuit board on the carrier, the conveyor belt can drive the carrier to displace a small distance towards the adsorption component to ensure that the adsorption component can still adsorb the circuit board on the carrier during the next action. As long as the working mode of the conveyor belt is set in advance, in addition, when the carrier is full of circuit boards, the weight will be very heavy. After the trolley pushes the carrier full of circuit boards onto the conveyor belt, under the conveying action of the conveyor belt, the carrier can be moved to a position close to the adsorption component and the loading part without manual pushing. Moreover, since the height of the conveyor belt is less than the height of the bosses, both sides of the carrier will be limited by the bosses to prevent the carrier from moving left and right during the process of transferring the circuit board, which may affect the loading.

[0031] Preferably, it further includes a frame, and both the conveying part and the carrying platform are arranged on the frame.

[0032] Therefore, the frame can provide support for the conveying part and the carrying platform, making the loading device form a whole and facilitating the overall movement. Description of the Drawings

[0038] Figures 1 to 3 The structure of a feeding device for a printed circuit board etching process according to an embodiment of the utility model is schematically shown.

[0039] See also Figures 1 to 3 The feeding device of the printed circuit board etching process includes a conveying part, a carrying platform 2, a feeding part 3, a rotating shaft 4, a driving device 5, an adsorption component 6, a push rod component, an L-shaped connecting rod 8, a conveyor belt 9, a carrying frame 10 and a frame 100.

[0040] See also Figure 1 and Figure 3 The conveying part includes a plurality of rollers 11 arranged in parallel. The conveying part is installed at the entrance end of the conveying line of the etching equipment. The rollers 11 can convey the circuit board to be etched to the etching equipment. The conveying part can be the conveying part of the etching equipment. In this embodiment, the four rollers 11 close to the supporting platform 2 are all discontinuous. Each discontinuous roller 11 includes three synchronously rotating sub-rollers 111. A gap is left between two adjacent sub-rollers 111 on the same roller 11, that is, each discontinuous roller 11 has two such gaps, and the gap is used to accommodate the loading piece 3.

[0041] See also Figure 1 and Figure 3 The carrying platform 2 is located at the side of the conveying part and the height of the carrying platform 2 is lower than the height of the roller 11. The carrying platform 2 is located in the upstream direction of the conveying part.

[0042] See also Figure 1 The conveying part and the carrying platform 2 are both installed on the frame 100. The frame 100 can provide support for the conveying part and the carrying platform 2, so that the loading device forms a whole, which is convenient for overall movement.

[0043] See alsoFigure 2 , the loading part 3 is used to transfer the circuit board to be etched on the carrier table 2 to the roller 11.

[0044] Refer to Figure 2 , the loading part 3 includes two parallel loading rods 31. The two loading rods 31 are fixed on the rotating shaft 4. The two loading rods 31 can rotate synchronously with the rotating shaft 4. The bottom end of the loading rod 31 is hook-shaped, and an inclined surface 311 is formed at the top end of the loading rod 31. A roller 312 is installed at the free end of the bottom end of the loading rod 31. The roller 312 can rotate freely on the loading rod 31. The specific installation method can be: an L-shaped connecting plate 313 is installed at the side position near the bottom end of the loading rod 31. The L-shaped connecting plate 313 is arranged in parallel with the loading rod 31. A hook-shaped part is formed between the L-shaped connecting plate 313 and the loading rod 31. The roller 312 is installed at the top of the L-shaped connecting plate 313; when the two loading rods 31 are respectively flipped into the gap between two adjacent sub-rollers 111 on the four non-continuous rollers 11, the inclined surface 311 at the top of the loading rod 31 can ensure that the circuit board carried on the loading rod 31 can be smoothly conveyed to the roller 11. In addition, when the adsorption component 6 adsorbs and transfers the circuit board onto the loading rod 31, the presence of the roller 312 can ensure that the bottom of the circuit board is smoothly slid into the hook-shaped part at the bottom of the loading rod 31, and can also prevent the free end of the bottom end of the loading rod 31 from scratching the circuit board.

[0045] Refer to Figure 1 and Figure 2 , two parallel mounting plates 41 are installed on the carrier table 2. One end of the rotating shaft 4 is installed on one mounting plate 41 through a bearing, and the other end of the rotating shaft 4 is installed on the other mounting plate 41 through a bearing. The rotating shaft 4 can rotate on the two mounting plates 41. One end of the L-shaped connecting rod 8 is fixed to the end of the rotating shaft 4, and the other end of the L-shaped connecting rod 8 is hinged to the drive shaft 51 of the drive device 5. The cylinder body of the drive device 5 is hinged to the carrier table 2. In this embodiment, the drive device 5 is a cylinder. In this way, when the drive shaft 51 of the drive device 5 (cylinder) makes an extending action, the rotating shaft 4 can be driven to rotate forward through the L-shaped connecting rod 8. The rotating shaft 4 rotating forward can drive the two loading rods 31 to flip to the end of the carrier table ( Figure 1In the state shown, when the drive shaft 51 of the drive device 5 (cylinder) retracts, the rotating shaft 4 can be driven to reverse through the L-shaped connecting rod 8. The reversed rotating shaft 4 can drive the two loading rods 31 to flip into the gap between two adjacent sub-cylinders 111 on the four continuous cylinders 11. Due to the fact that the cylinder body of the drive device 5 is hinged on the carrying platform 2 and the effect of the L-shaped connecting rod 8, the linear motion of the drive shaft 51 of the drive device 5 (cylinder) can be converted into the circular motion of the rotating shaft 4. In other embodiments, the drive device 5 can also be a motor, and the motor is mounted on the mounting plate 41 through a bracket, and the motor drives the rotating shaft 4 to rotate forward or reverse.

[0046] Refer to Figure 2 , a support plate 602 is installed between the two mounting plates 41, and a fixing plate 603 is installed on the support plate 602. The adsorption component 6 includes a cylinder 61, a push plate 62 and a vacuum chuck 63. The cylinder 61 is fixed on the fixing plate 603, the push plate 62 is fixed on the piston rod 601 of the cylinder 61, and the vacuum chuck 63 is installed on the push plate 62. The vacuum chuck 63 adopts an existing structure, and the working principle of the vacuum chuck 63 will not be elaborated. The vacuum chuck 63 can adsorb and transfer the circuit board on the carrying platform 2 to the loading part 3. In this embodiment, the number of vacuum chucks 63 is four, and the four vacuum chucks 63 are arranged in parallel on the push plate 62. When the loading part 3 flips to the end of the carrying platform 2 ( Figure 1 in the state shown), the piston rod 601 of the cylinder 61 extends, the push plate 62 moves towards the circuit board on the carrying platform 2, and the push plate 62 drives the vacuum chuck 63 to move towards the circuit board on the carrying platform 2. The vacuum chuck 63 forms a negative pressure by pumping air, so that the vacuum chuck 63 adsorbs on the circuit board. Then the piston rod 601 of the cylinder 61 retracts, the push plate 62 moves away from the carrying platform 2, and the push plate 62 drives the vacuum chuck 63 to move away from the carrying platform 2. The vacuum chuck 63 transfers the adsorbed circuit board to the loading part 3. Then the vacuum chuck 63 is filled with air, and the vacuum chuck 63 is separated from the circuit board. The circuit board is completely transferred to the loading part 3, and the loading part 3 can transfer the circuit board to be etched to the cylinder 11. When the vacuum chuck 63 adsorbs and transfers the circuit board on the carrying platform 2 to the two loading rods 31, since the bottom end of the loading rod 31 is hook-shaped, the bottom end of the loading rod 31 will hold up the circuit board upwards, ensuring that the circuit board will not slip off the loading rod 31 during the flipping process. When the two loading rods 31 flip to the end of the carrying platform 2 to transfer the next circuit board, as long as it is ensured that the opening of the hook shape at the bottom of the loading rod 31 is inclined upwards towards the carrying platform 2 (which can be set by the stroke of the drive device 5, i.e., the cylinder), under the action of the vacuum chuck 63, the circuit board on the carrying platform 2 can be transferred to the two loading rods 31.

[0047] Refer to Figure 2, the ejector rod component includes an ejector rod 71, a spring 72 and a limit ring 73. One end of the ejector rod 71 is formed with a top 711, and the diameter of the top 711 is greater than that of the ejector rod 71. The other end of the ejector rod 71 is inserted into the push plate 62 and can slide in the push plate 62. Two vacuum suction cups 63 are respectively distributed on both sides of the ejector rod 71. The limit ring 73 is sleeved on the other end of the ejector rod 71 and is fixed on the ejector rod 71. The spring 72 is sleeved on the ejector rod 71. One end of the spring 72 abuts against the push plate 62, and the other end of the spring 72 abuts against the top 711 of the ejector rod 71. The limit ring 73 can prevent the ejector rod 71 from disengaging from the push plate 62. When the spring 72 is in a natural state, the distance from the top 711 of the ejector rod 71 to the push plate 62 is greater than the distance from the vacuum suction cup 63 to the push plate 62; when the two loading rods 31 are flipped to the end of the loading platform 2, the piston rod 601 of the air cylinder 61 makes an extending action, and the push plate 62 moves towards the circuit board on the loading platform 2. The push plate 62 drives the vacuum suction cup 63 and the ejector rod component to move towards the circuit board on the loading platform 2. Since the distance from the top 711 of the ejector rod 71 to the push plate 62 is greater than the distance from the vacuum suction cup 63 to the push plate 62 in the natural state, the top 711 of the ejector rod 71 will first contact the circuit board. As the push plate 62 continues to move, the circuit board will press the top 711 of the ejector rod 71 to make the ejector rod 71 slide in the push plate 62. At the same time, the spring 72 on the ejector rod 71 is compressed. When the vacuum suction cup 63 contacts the circuit board, the vacuum suction cup 63 forms a negative pressure by pumping air, so that the vacuum suction cup 63 adsorbs on the circuit board. Then the piston rod 601 of the air cylinder 61 makes a retracting action, and the push plate 62 moves away from the loading platform 2. The push plate 62 drives the vacuum suction cup 63 to move away from the loading platform 2. The vacuum suction cup 63 transfers the adsorbed circuit board above the hook-shaped part of the loading rod 31. Then the vacuum suction cup 63 is filled with air. Under the restoring force of the spring 72 on the ejector rod 71, the top 711 of the ejector rod 71 will push the circuit board away from the vacuum suction cup 63, so as to separate the circuit board from the vacuum suction cup 63. The circuit board is completely transferred onto the two loading rods 31, and the bottom of the circuit board is accommodated in the hook-shaped part on the loading rod 31. The two loading rods 31 can transfer the circuit board to be etched onto the roller 11. The presence of the ejector rod component can ensure that when the vacuum suction cup 63 is filled with air, the circuit board and the vacuum suction cup 63 can be completely separated, preventing unnecessary adsorption so that the circuit board cannot be completely transferred onto the loading rod 31.

[0048] Refer to Figures 1 to 3 , two parallelly arranged bosses 21 are installed on the loading platform 2. The conveyor belt 9 is installed between the two bosses 21. The height of the conveyor belt 9 is less than the height of the boss 21. The conveying direction of the conveyor belt 9 is consistent with the length direction of the boss 21. The number of the conveyor belts 9 is two. One closed conveyor belt 9 is close to one boss 21, and the other closed conveyor belt 9 is close to the other boss 21. Loading racks 10 can be placed on the two conveyor belts 9 (Figure 3 As shown, the height of the bearing surface of the carrier for receiving the circuit board is slightly higher than that of the boss 21, and the two loading rods 31 can transfer the circuit board on the carrier to the roller 11.

[0049] Refer to Figure 3 The carrier 10 is used for transferring the circuit board. Multiple circuit boards to be etched stacked horizontally are placed on the carrier 10. The carrier 10 is placed on the two conveyor belts 9 and is located between the two bosses 21. The height of the bearing surface of the carrier 10 for receiving the circuit board is slightly higher than that of the boss 21, and the width of the carrier 10 is slightly smaller than the distance between the two bosses 21. The two loading rods 31 and the adsorption component can transfer the circuit board on the carrier 10 to the roller 11 of the conveying part. When the vacuum chuck 63 of the adsorption component adsorbs and transfers a circuit board on the carrier 10, the conveyor belt 9 can drive the carrier 10 to displace a short distance in the direction of the vacuum chuck 63 of the adsorption component to ensure that the vacuum chuck 63 can still adsorb the circuit board on the carrier 10 during the next operation. As long as the working mode of the conveyor belt 9 is set in advance. In addition, when the carrier 10 is full of circuit boards, the weight will be very heavy. After the trolley pushes the carrier 10 full of circuit boards onto the conveyor belt 9, under the conveying action of the conveyor belt 9, the carrier 10 can be moved to a position close to the adsorption component and the loading part 3, without manual pushing. Moreover, since the height of the conveyor belt 9 is less than the height of the boss 21, the two sides of the carrier 10 will be limited by the boss 21 to prevent the carrier 10 from moving left and right during the process of transferring the circuit board, which affects the loading. The height of the trolley can be designed to be equivalent to the height of the conveyor belt 9. In this way, the carrier 10 on the trolley can be very easily conveyed to a position close to the adsorption component and the loading part 3 through the conveyor belt 9, which is very convenient.

[0050] Refer to Figure 3The conveying part of the loading device of the printed circuit board etching process of the utility model is installed at the entrance end of the conveying line of the etching equipment. The roller 11 can convey the circuit board to be etched to the etching equipment. Under the action of the vacuum suction cup 63 and the conveyor belt 9, the vacuum suction cup 63 can absorb and transfer the circuit board on the carrier 10 to the two loading rods 31, and the bottom of the circuit board is accommodated in the hook-shaped part on the loading rod 31. Then, under the action of the driving device 5, the rotating shaft 4 drives the two loading rods 31 to flip, and the two loading rods 31 can transfer the circuit board to be etched to the roller 11. The rotating roller 11 conveys the circuit board to be etched to the etching equipment for etching. Then, under the action of the driving device 5, the rotating shaft 4 drives the two loading rods 31 to flip in the opposite direction. The two loading rods 31 flip to the end of the supporting platform 2 and wait for the vacuum suction cup 63 to adsorb and transfer the next circuit board to the two loading rods 31. The loading device of the utility model can drive the two loading rods 31 to flip and flip in the opposite direction and the vacuum suction cup 63 to adsorb and cooperate to transfer the circuit board to be etched on the carrier frame 10 on the supporting platform 2 to the roller 11 of the conveying part through the driving device 5. Since the conveying part can be the conveying part of the etching equipment, the core structure of the loading device of the utility model is the driving device 5, the rotating shaft 4, the two loading rods 31, the cylinder 61 and the vacuum suction cup 63. It has a simple structure and low cost. It only needs to set the working mode of the driving device 5 and the adsorption component (cylinder 61 and vacuum suction cup 63) in advance.

[0051] The above are only some embodiments of the present invention, which are intended to illustrate the technical means of the present invention, but not to limit the technical scope of the present invention. Those skilled in the art can make obvious improvements to the present invention in combination with existing common knowledge, which all fall within the protection scope of the present invention.
