New energy vehicle circuit boards require multiple handling and conveying operations during the processing and production process, especially in the circuit board processing and loading process. It is usually necessary to grab piles of circuit board raw materials and place them one by one on the conveyor belt for loading and conveying operations.

[0003] In the process of grabbing and transporting piles of circuit boards one by one, since most of the existing circuit board conveying and handling devices rely on mechanical gripper structures for gripping operations, due to the thin thickness of the circuit board raw material board, as well as factors such as electrostatic adhesion and tiny adsorption force, in actual operation, the mechanical gripper is very likely to have adhesion and multiple grips during the gripping process. Once multiple circuit boards are gripped at a time, the subsequent processing equipment will not be able to normally handle the multiple adhered circuit boards, which will not only interrupt the processing, but also require manual intervention for cleaning and re-sorting, which greatly affects the efficiency of processing and transportation. In addition, frequent manual intervention is likely to disrupt the automated production rhythm of the production line, resulting in overall production efficiency being affected.

Under the cooperation of each other, the cleaning of the circuit board before processing is integrated into the process of grabbing and transporting, which can effectively improve the overall processing efficiency of the circuit board. At the same time, by connecting the air driving unit to the air flow path between the first air outlet and the air blowing box, the air flow will first drive the air driving unit to drive the arc-shaped slider to slide in the arc-shaped slide groove before entering the air blowing box, and close the air flow supply at the nozzle in advance, which is conducive to concentrating the air flow in the air blowing box for spraying, so as to facilitate more efficient air blowing cleaning of the bottom of the circuit board without affecting the grabbing and transporting of the device. 4.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides a new energy vehicle circuit board handling device, see Figure 1 - Fig.10 Specifically, it includes a base 1, a first electric conveyor belt 101 arranged longitudinally is installed at the front end of the base 1, a second electric conveyor belt 103 located behind the first electric conveyor belt 101 is installed on the base 1, a frame 104 is fixedly installed on the base 1 and is erected between the first electric conveyor belt 101 and the second electric conveyor belt 103, and a longitudinal electric slide rail 105 is fixedly installed on the frame 104, a second electric push rod 106 arranged vertically is fixedly installed at the sliding end of the electric slide rail 105, and a grabbing mechanism 2 is installed on the telescopic end below the second electric push rod 106.

[0021] When the device is in use, the staff uses it to grab the stacked new energy vehicle circuit boards one by one and place them on the second electric conveyor belt 103, and then use the second electric conveyor belt 103 to transport and load the circuit boards one by one. During use, the staff places the neatly stacked piles of circuit boards from the front end of the device above the front end of the first electric conveyor belt 101, and then after the first electric conveyor belt 101 is powered on and started, the piles of circuit boards placed thereon are transported backwards and transported to the rear end of the first electric conveyor belt 101. At this time, the piles of circuit boards are ready to be grabbed one by one at the rear end of the first electric conveyor belt 101. The moving end of the electric slide rail 105 controls the second electric push rod 106 to drive the grabbing mechanism 2 to move forward to above the piles of circuit boards at the rear end of the first electric conveyor belt 101, and then the second electric push rod 1 06 telescopic end drives the grasping mechanism 2 to move downward to grasp the top circuit board of the pile of circuit boards. After the top circuit board is grasped, the second electric push rod 106 controls the grasping mechanism 2 to carry the circuit board upward, and then the electric slide rail 105 drives the second electric push rod 106 to drive the grasping mechanism 2 to carry the grasped circuit board backward to above the front end of the second electric conveyor belt 103, and the grasping mechanism 2 is controlled by the second electric push rod 106 to carry the circuit board downward again, and a single circuit board is placed on the second electric conveyor belt 103, and then the second electric conveyor belt 103 is powered on and started to convey the single circuit board placed at its front end backward, and through the cooperation of the electric slide rail 105, the second electric push rod 106 and the grasping mechanism 2, the stacked circuit boards at the rear end of the first electric conveyor belt 101 are grasped one by one onto the second electric conveyor belt 103 for orderly backward conveying operation.

[0022] In the specific implementation process, Figure 4 - Figure 8As shown, the grasping mechanism 2 includes a carrying plate 201, and a connecting frame 202 fixedly connected to the telescopic end of the second electric push rod 106 is fixedly installed at the middle position of the top of the carrying plate 201, a gas nozzle joint 203 is fixed on the carrying plate 201, and a plurality of nozzles 204 connected to the gas nozzle joint 203 are arranged at the bottom of the carrying plate 201. The bearing plate 201 is fixedly installed with an axle seat 3 at the edge positions around the bearing plate 201, and a hinged rod 301 is hinged on the axle seat 3, and a pneumatic push rod 302 is hinged between the axle seat 3 and the hinged rod 301. The pneumatic push rod 302 includes a cylinder body 3021 rotatably installed on the axle seat 3, and a telescopic rod body 302 is slidably inserted in the cylinder body 3021. 22, one end of the telescopic rod body 3022 is hinged to the first rod body 3011, and the other end of the telescopic rod body 3022 is fixed with a piston block 3023 slidably installed in the cylinder body 3021, and the cylinder body 3021 is provided with a first air inlet 3024 at one end away from the telescopic rod body 3022, and a first air outlet 3025 is provided at the middle position of the cylinder body 3021, and the telescopic rod body 3022 is movably sleeved with a spring 3026 installed in the cylinder body 3021, and the spring 3026 is elastically supported between the inner end wall of the cylinder body 3021 and the piston block 3023, and a clamping plate 303 is installed at one end of the hinged rod 301 extending to the outside of the bearing plate 201.

[0023] When the device is in use, in the process of using the grasping mechanism 2 to grasp the circuit board, the bottom of the carrier plate 201 approaches the top of the circuit board under the moving control, and the air pump is connected to the air nozzle joint 203 to supply high-speed airflow. The airflow enters each nozzle 204 through the air nozzle joint 203, and is ejected downward from the nozzle 204 to act on the upper surface of the circuit board. Since the distance between the bottom of the nozzle 204 and the top of the circuit board is limited, under the stopper of the top of the circuit board, the high-speed airflow blown out from the bottom of the nozzle 204 spreads to the surroundings, forming a high-speed airflow layer between the bottom of the carrier plate 201 and the circuit board. Since the faster the airflow velocity, the lower the pressure, the air pressure at the top of the circuit board is lower than the air pressure at the bottom. Under the influence of the Bernoulli effect, a negative pressure adsorption force is finally formed between the carrier plate 201 and the circuit board, forming a contactless connection with the circuit board, and then the carrier plate 201 moves upward under the drive of the telescopic end of the second electric push rod 106, so that the top circuit board of the pile of circuit boards is separated from the other circuit boards below. In this process, the next circuit board will not be grasped in conjunction.

[0024] When the topmost circuit board is grabbed and separated from the circuit board pile, the air pump fills air into the cylinder 3021 through the first air inlet 3024. The filled air pushes the piston block 3023 to move in the cylinder 3021, driving the telescopic rod body 3022 to slide outward. Since the telescopic rod body 3022 is hinged to the hinge rod 301, the hinge rod 301 is pushed by the pneumatic push rod 302 to deflect and swing downward around the shaft seat 3, driving the clamping plate 303 installed at the end of the hinge rod 301 to flip downward and buckle at the edge of the circuit board, thereby placing a double restriction on the grabbing of the circuit board. The device first A single circuit board is independently grabbed by negative pressure adsorption formed by high-speed airflow. After a single circuit board is separated from the circuit board pile, the pneumatic push rod 302 is controlled to push the hinge rod 301 to deflect, driving the clamping plate 303 to be buckled at the edge of the circuit board. With double coordination, it can not only ensure the stability of the circuit boards being grabbed and conveyed one by one, but also avoid the circuit boards from falling off due to equipment vibration and shaking during the grabbing and conveying process, and ensure the position accuracy of the circuit boards during grabbing and conveying. The contactless adsorption combined with the physical contact restriction can effectively improve the stability and safety of the circuit board grabbing and handling process.

[0025] When it is necessary to lower the circuit board, the staff interrupts the air flow supply to the first air inlet 3024, and under the elastic reset of the spring 3026, pushes the piston block 3023 to drive the telescopic rod body 3022 to reset and retract into the cylinder body 3021, and then pulls the hinged rod 301 to drive the clamping plate 303 to flip upward, thereby releasing the restriction on the edge position of the circuit board. At the same time, the air flow sprayed from the nozzle 204 is interrupted, releasing the negative pressure adsorption connection above the circuit board, and completing the circuit board lowering operation.

[0026] In the specific implementation process, Figure 2 and Figure 3As shown, a first electric push rod 102 is fixedly installed on the base 1 below the rear end of the first electric conveyor belt 101, and a tray is fixedly installed on the telescopic end above the first electric push rod 102. When the device is in use, after the top circuit boards of the pile of circuit boards at the rear end of the first electric conveyor belt 101 are grabbed and transferred one by one, the height of the top of the pile of circuit boards is gradually reduced. At this time, the position height of the grabbing mechanism 2 is adjusted only by lifting and lowering the telescopic end of the second electric push rod 106, which will cause the grabbing mechanism 2 to grab the top circuit board. The moving stroke is too large, which affects the movement of the circuit boards one by one. In order to improve the efficiency of transportation, at this time, the first electric push rod 102 installed under the rear end of the first electric conveyor belt 101 is powered on and started. When the height of the top of the pile of circuit boards is lowered due to the transportation of the circuit boards, the telescopic end of the first electric push rod 102 controls the tray to move upward, and lifts the pile of circuit boards upward, so that the height of the top of the pile of circuit boards can always remain at the same position during the transportation process. This can not only avoid the second electric push rod 106 from affecting the efficiency of grabbing and transportation due to the gradual increase in stroke, but also effectively improve the accuracy of the second electric push rod 106 in controlling the grabbing mechanism 2 to grab the top circuit board.

[0027] In the specific implementation process, Figure 4 - Figure 6 and Figure 8 As shown, the hinged rod 301 includes a first rod body 3011 hinged with the shaft seat 3, and a square box 3012 is fixedly installed at one end of the first rod body 3011 away from the shaft seat 3, and a second rod body 3013 is slidably inserted in the square box 3012, and a bolt 3014 is screwed on the outer end wall of the square box 3012 away from the first rod body 3011, and the bolt 3014 points to the outer end wall of the second rod body 3013, and the clamping plate 303 is vertically installed below the end of the second rod body 3013 away from the square box 3012. When the device is in use, the end of the bolt 3014 is tightly pressed against the outer end wall of the second rod body 3013, which makes the second rod body 3013 and the square box 3012 maintain a relatively stable state. In actual use, due to the sliding connection between the second rod body 3013 and the bolt 3014, workers can The staff can flexibly adjust the hinged rod 301 in various directions according to the size of the circuit board to be grabbed. With the help of the threaded connection between the bolt 3014 and the square box 3012, the staff can loosen the squeezing and clamping of the second rod body 3013 by twisting the bolt 3014. When the bolt 3014 is loosened, the staff pulls the second rod body 3013 to adjust the overall length of the hinged rod 301, so that the clamping plate 303 installed at the end of the second rod body 3013 can be flexibly adjusted according to the actual clamping needs. Under the drive of the pneumatic push rod 302, the circuit boards of different sizes can be stably clamped after flipping. After the adjustment is appropriate, the staff reversely rotates the bolt 3014 to re-clamp and fix the second rod body 3013. The adjustment is flexible and convenient, and it is beneficial to improve the application range of the device.

[0028] In the specific implementation process, Figure 5 , Figure 6 and Figure 8 As shown, an air blowing box 304 is fixedly installed at the lower end of the clamping plate 303, and an opening is provided on the side of the air blowing box 304 facing the carrier plate 201, and the interiors of the numerous air blowing boxes 304 and the numerous first air outlets 3025 are in a connected state. When the device is in use, the airflow is ejected from the nozzle 204 and acts on the upper surface of the circuit board, which can not only negatively adsorb and connect the circuit board, but also clean the upper surface of the circuit board by blowing the high-speed airflow.

[0029] Similarly, when air flows into the cylinder 3021 through the first air inlet 3024 and pushes the piston block 3023, the piston block 3023 moves in the cylinder 3021. When the piston block 3023 moves over the first air outlet 3025, the first air outlet 3025 opened in the middle position of the outer end wall of the cylinder 3021 is in a connected state. Since the first air outlet 3025 is in a connected state with the inside of the air blowing box 304, in this state, the air flow enters the air blowing box 304 through the first air outlet 3025, and then is ejected through the air blowing box 304 toward the opening on the side of the carrier plate 201. The opening is set to a flat structure, which can evenly disperse the ejected air flow toward the bottom of the carrier plate 201. The above operation enables the device to perform air blowing cleaning on the bottom of the circuit board during the process of grabbing and transporting the circuit board, and integrates the cleaning of the circuit board before processing into the grabbing and transporting process, which can effectively improve the overall processing efficiency of the circuit board.

[0030] In the specific implementation process, Figure 5 - Figure 7 and Fig. 9 - Fig.10 As shown, multiple nozzles 204 are distributed around the middle position of the bottom of the supporting plate 201, a main channel 4 connected to the air nozzle joint 203 is opened in the supporting plate 201, and the main channel 4 is sleeved on the outside of the multiple nozzles 204, a diversion channel 401 connected between the main channel 4 and each nozzle 204 is opened in the supporting plate 201, an arc-shaped slide groove 402 for cutting off the diversion channel 401 is opened in the supporting plate 201, multiple arc-shaped slide grooves 402 are distributed around the middle position of the supporting plate 201 and are concentrically arranged with the middle position of the supporting plate 201, a ring plate 403 is rotatably installed on the top of the supporting plate 201, and an arc-shaped slider 404 slidably installed in the arc-shaped slide groove 402 is fixed around the bottom of the ring plate 403, a through hole 405 corresponding to the diversion channel 401 is opened on the arc-shaped slider 404, a first gear ring 406 is fixedly installed on the ring plate 403, and an air drive unit 5 is installed on the supporting plate 201.

[0031] The air drive unit 5 includes an inner cylinder 501 fixedly connected to the carrier plate 201, and a vertically arranged rotating shaft 502 is rotatably installed at the inner axis position of the inner cylinder 501, an outer cylinder 503 movably sleeved on the outer side of the inner cylinder 501 is fixedly installed at the bottom end of the rotating shaft 502, a limit block 504 is fixedly installed in the inner cylinder 501, a valve plate 505 adapted to the internal size of the inner cylinder 501 is fixed in the outer cylinder 503, and a second air inlet 506 and a second air inlet 506 are connected to the top two sides of the inner cylinder 501 respectively. Air outlet 507, a shell 508 is fixed on the top of the inner cylinder 501, and a spring 509 is installed in the shell 508, the outer end of the spring 509 is fixedly connected to the inner end wall of the shell 508, the inner end of the spring 509 is fixedly connected to the top of the rotating shaft 502, and the outer side of the outer cylinder 503 is fixedly sleeved with a second gear ring 510 meshing with the first gear ring 406, a plurality of first air outlets 3025 are connected to the second air inlet 506, and a plurality of air blowing boxes 304 are directly connected to the second air outlet 507.

[0032] During the process of grabbing the circuit board and transporting it, the bottom of the circuit board is cleaned by the air flow blown out from the air blowing box 304, which increases the air flow velocity at the bottom of the circuit board and gradually approaches the pressure difference between the upper and lower sides of the circuit board. In this state, it is difficult for the air flow ejected from the nozzle 204 to form an effective negative pressure adsorption effect above the circuit board. Therefore, when the air flow is ejected from the first air outlet 3025 to the inside of the air blowing box 304, it will first enter the inside of the inner cylinder 501 through the second air inlet 506. Under normal circumstances, the spring 509 is in a relaxed state, and the valve plate 505 is horizontally placed between the second air inlet 506 and the second air outlet 507. When the air flow enters the inner cylinder 501 through the second air inlet 506, it will push the valve plate 505 to slide in the inner cylinder 501 until the valve plate 505 passes over the second air outlet 507. Only then will the air flow flow to the inside of the air blowing box 304 through the second air outlet 507. During this process, the outer cylinder 503 is driven to rotate. , and the spring 509 is wound and compressed. During the rotation of the outer cylinder 503, the second gear ring 510 and the first gear ring 406 are meshed to transmit the rotational power to the ring plate 403, driving the multiple arc-shaped sliders 404 below the ring plate 403 to slide in the corresponding arc-shaped slide grooves 402. When the ring plate 403 does not rotate, the through hole 405 is connected to the corresponding shunt channel 401. When the ring plate 403 is driven to rotate and drive the arc-shaped slider 404 to rotate, the arc-shaped slider 404 is blocked in the shunt channel 401, and the arc-shaped slider 404 is cut off. At this time, the airflow cannot enter the corresponding nozzle 204 through the shunt channel 401, and the airflow injection in the nozzle 204 is released. After the clamping plate 303 completes the limit clamping of the circuit board, the airflow injection at the nozzle 204 is automatically interrupted, and the airflow is concentrated in the air blowing box 304 for spraying, so that the bottom of the circuit board is more efficiently cleaned by air blowing, which is conducive to improving the efficiency of the air blowing cleaning of the device during the process of transporting the circuit board.

[0033] When the grabbing and transporting is completed, the clamping plate 303 needs to release the clamping of the circuit board, and the airflow charging at the first air inlet 3024 is interrupted. Synchronously, the airflow charging at the second air inlet 506 is interrupted. After the valve plate 505 loses the push of the airflow, the spring 509 elastically resets and expands, and drives the outer cylinder 503 to rotate in the opposite direction and reset through the rotating shaft 502. With the help of the meshing transmission of the second gear ring 510 and the first gear ring 406, the ring plate 403 drives the arc-shaped slider 404 to slide in the opposite direction and reset in the corresponding arc-shaped slide groove 402, and the through hole 405 is reconnected to the corresponding diversion channel 401. In this state, the airflow can re-enter the nozzle 204 through the diversion channel 401 and be sprayed out, so as to facilitate the subsequent repeated grabbing and transporting of the circuit board.

[0034] In the specific implementation process, Figure 5 - Figure 7 and Fig. 9 As shown, the upper end of each nozzle 204 is fixedly connected to a cylinder 6, and the interior of the cylinder 6 is connected to the diversion channel 401 at the corresponding position, a valve block 601 is slidably installed in the cylinder 6, a pipe joint 602 is fixedly installed on the top of the cylinder 6, and a two-way micro oil pump 603 is fixedly installed on the supporting plate 201, the pipe joint 602 at the top of the cylinder 6 at an odd position is connected to one port of the two-way micro oil pump 603, and the pipe joint 602 at the top of the cylinder 6 at an even position is connected to the other port of the two-way micro oil pump 603.

[0035] When the device is used, the valve block 601 in the cylinder 6 at the odd position is at the lower position inside the cylinder 6, and the valve block 601 in the cylinder 6 at the even position is at the upper position inside the cylinder 6. The cylinder 6 is filled with hydraulic oil located above the valve block 601. When the bidirectional micro oil pump 603 is started in the forward direction, the hydraulic oil on the valve block 601 in the cylinder 6 at the odd position can be pumped into the valve block 601 in the cylinder 6 at the even position. In this process, the valve block 601 in the cylinder 6 at the odd position is 601 moves upward, and the valve block 601 in the even-numbered cylinder 6 moves downward. When the two-way micro oil pump 603 is started in reverse, the hydraulic oil on the valve block 601 in the even-numbered cylinder 6 can be pumped into the valve block 601 in the odd-numbered cylinder 6. During this process, the valve block 601 in the even-numbered cylinder 6 moves upward, and the valve block 601 in the odd-numbered cylinder 6 moves downward. Through the reciprocating start of the two-way micro oil pump 603, the valve block 601 is controlled to move up and down in the cylinder 6 in a cycle.

[0036] A one-way valve is provided in the shunt channel 401, so that the airflow can only flow into the corresponding cylinder 6 through the shunt channel 401, and the airflow in the cylinder 6 cannot flow back through the shunt channel 401. A one-way valve is provided in the nozzle 204, so that the airflow can only be ejected outward through the nozzle 204, and the external airflow cannot enter the cylinder 6 through the nozzle 204. When the valve block 601 moves upward in the cylinder 6, the speed of the airflow in the shunt channel 401 filling into the cylinder 6 can be accelerated. When the valve block 601 moves downward in the cylinder 6, the airflow in the shunt channel 401 can be accelerated. When moving, the driving force provided by the rapid downward movement of the valve block 601 allows the airflow in the cylinder 6 to be ejected downward through the nozzle 204 more quickly, greatly improving the flow rate of the airflow ejected from the nozzle 204 toward the top of the circuit board. The faster the flow rate, the smaller the air pressure, and the greater the pressure difference between the upper and lower sides of the circuit board, which can effectively improve the stability of the device in grasping the circuit board through negative pressure adsorption. In addition, the faster the flow rate of the airflow ejected from the nozzle 204, the greater the air blowing impact force, which can effectively improve the effect of air blowing cleaning on the top of the circuit board.

[0037] Under the reciprocating drive of the bidirectional micro oil pump 603, the nozzles 204 at odd positions and the nozzles 204 at even positions operate alternately, which can effectively ensure the stability of the circuit board being adsorbed and grasped by the airflow ejected from the numerous nozzles 204. A one-way valve may not be provided in the nozzle 204. When operating in this mode, when the valve block 601 moves upward in the cylinder 6 to converge the airflow, the nozzle 204 can provide suction force to the circuit board below, which acts in the opposite direction to the airflow blown out from the adjacent nozzle 204. Under the cooperation with each other, the stability of the circuit board when being grasped by the device can also be improved.

[0038] Specifically, the working principle and operation method of the present invention are as follows: The staff places the pile of circuit boards on the first electric conveyor belt 101 from the front end of the device, and transports them to the rear end position through the first electric conveyor belt 101. Then the electric slide rail 105 cooperates with the second electric push rod 106 to adjust the position of the grabbing mechanism 2, so that the carrier plate 201 fits the top of the pile of circuit boards. Then the air pump supplies high-speed airflow into the air nozzle joint 203. The airflow passes through the connection between the main channel 4 and the branch channel 401, enters the cylinder 6, and then sprays downward through the corresponding nozzle 204. The airflow blows a high-speed flow between the top of the top circuit board and the bottom of the carrier plate 201. The air flow layer realizes contactless connection between the circuit board and the bottom of the carrier plate 201 by means of negative pressure adsorption. During the negative pressure adsorption process, the two-way micro oil pump 603 is started reciprocatingly to drive the hydraulic oil to circulate in the cylinder 6 of odd-numbered positions and the cylinder 6 of even-numbered positions, thereby pushing the valve block 601 to move up and down reciprocatingly in the cylinder 6. When the valve block 601 moves upward in the cylinder 6, the efficiency of the air flow in the diversion channel 401 merging into the cylinder 6 can be accelerated. When the valve block 601 moves downward in the cylinder 6, the efficiency of the air flow spraying out through the nozzle 204 can be accelerated, thereby improving the stability and firmness of the circuit board negative pressure adsorption on the bottom of the carrier plate 201.

[0039] During the process of the upper circuit board being grabbed by the carrier plate 201 and moving toward the upper front end of the second electric conveyor belt 103, the airflow provided by the air pump enters the cylinder body 3021 through the first air inlet 3024, pushing the piston block 3023 to drive the telescopic rod body 3022 to extend outward, and through the hinged connection, driving the hinged rod 301 to drive the clamping plate 303 to flip downward and buckle on the edge of the circuit board, thereby performing a double restriction on the circuit board. The staff can adjust the length of the hinged rod 301 by sliding the second rod body 3013, so that the device is suitable for clamping circuit boards of different sizes.

[0040] After the airflow entering the cylinder body 3021 is discharged through the first air outlet 3025, it enters the inner cylinder 501 through the second air inlet 506, pushes the valve plate 505 to slide in the inner cylinder 501, and then is discharged through the second air outlet 507. During the sliding process of the valve plate 505, the outer cylinder 503 is driven to rotate. With the help of the engagement of the second gear ring 510 and the first gear ring 406, the ring plate 403 drives the arc-shaped slider 404 to slide in the corresponding arc-shaped slide groove 402, so that the arc-shaped slider 404 blocks and cuts off the diversion channel 401, and cuts off the airflow at the nozzle 204. The airflow provided by the air pump can be concentrated and provided to the cylinder body 3021, and then enters the inner cylinder 501, and is finally transported to the inside of each air blowing box 304 through the second air outlet 507 for spraying, so that the bottom of the circuit board is cleaned by air blowing during the transportation process.

[0041] After the grabbing mechanism 2 grabs the circuit board and moves it to the second electric conveyor belt 103, the air pump stops supplying air. After losing the airflow push, the hinged rod 301 drives the clamping plate 303 to rotate in the opposite direction under the elastic reset of the spring 3026, releases the pressure on the edge of the circuit board, places the circuit boards on the second electric conveyor belt 103, and transports them backward one by one through the second electric conveyor belt 103. After the airflow into the cylinder body 3021 is interrupted, the airflow into the inner cylinder 501 is also interrupted. With the help of the elastic rebound of the clockwork 509, the outer cylinder 503 is driven to rotate in the opposite direction, and then drives the arc-shaped slider 404 to move in the opposite direction and reset in the arc-shaped slide groove 402, and the through hole 405 is reconnected in the diversion channel 401 to ensure that the air supply at the nozzle 204 is connected in the subsequent grabbing process.

[0042] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
