Description

A dust removal device for electronic components and a method of using the same

Technical Field

The invention relates to the field of dust removal of electronic components, and in particular to a dust removal device for electronic components and a use method thereof.

Background Art

Electronic transformers, relays, printed circuit boards, integrated circuits, various circuits, electronic chemical materials and parts are all types of electronic components. In order to reduce the assembly accuracy of power components and prevent dust pollutants from invading and affecting product quality, many electronic components currently need to be dust-removed after production.

At present, the circuit board also needs to be dusted before being welded with other electronic components. At this time, a dust removal device is needed. There are various devices on the market for dust removal of electronic components. The most commonly used one is contactless wind dust removal. Its main components are: rack, ion fan, dust suction component, feed plate, slide rail and electric push rod. When in use, the circuit board is first glued to the feed plate with tape, and there are multiple sets of leakage holes on the feed plate. The electric push rod can push the feed plate into the rack. At this time, the sprayer component and the dust suction component will be started synchronously to remove the dust from the circuit board on the feed plate. After the treatment, the electric push rod will pull the circuit board back to its original position through the feed plate. At this time, the staff can remove the circuit board, that is, the dust removal of the circuit board is completed. At present, many manufacturers can set card parts to restrict the circuit board on the feed plate according to the model of the circuit board to be processed, eliminating the operation of sticking the circuit board with tape.

However, when the dust removal device for the circuit board mentioned above processes the circuit board, the angle of the circuit board is fixed. During the dust removal process, the ion fan continuously blows air to the top surface of the circuit board to achieve the dust removal operation. However, since the surface of the circuit board is not completely flat, there will be some uneven positions. During the continuous blowing process, occasionally some dust will be adsorbed on the uneven parts of the circuit board under the action of wind, resulting in dust still being found in subsequent inspections, causing this circuit board to need to be reworked for secondary processing. At present, some manufacturers, in order to avoid the occurrence of such accidents, will also install cleaning devices such as brushes in the dust removal device. While the circuit board is being dusted by wind, the circuit board is also cleaned by brushing. However, this solution will cause contact between the brush and the circuit board. Regardless of whether the brush is harder or softer, it will cause certain wear on the circuit board. In particular, the contact between the harder brush and the circuit board is very easy to cause damage to the circuit board. This solution still has certain problems. Therefore, it is urgently needed to improve on the basis of the existing dust removal device for circuit boards.

Summary of the invention

Based on this, the purpose of the present invention is to provide a dust removal device for electronic components and a method of using the same, so as to solve the technical problems mentioned in the above background technology.

To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dust removal device for electronic components, comprising a body, an inspection door, a circuit board, an ion fan and a dust collector, a support plate is installed on the outer wall of the body, a support frame is arranged on the top of the support plate, a pulley is installed on the outer wall of the support frame, a slide rail for guiding the pulley is installed on the top of the support plate, a transmission frame is rotatably installed on the outer wall of the support frame, and an electric push rod connected to the transmission frame is installed on the top of the support plate;

The present invention is further configured such that a plurality of groups of support wheels for supporting the circuit board are evenly spacedly installed on the top of the transmission rack, the horizontal plane at the top of the transmission rack is lower than the horizontal plane at the bottom of the clamp, and the top of the support wheel is on the same horizontal plane as the bottom of the clamp.

By adopting the above technical solution, under the action of the supporting wheel, the transmission rack will not directly contact the circuit board, thereby reducing the damage to the circuit board caused by the transmission rack when sliding.

The present invention is further configured as described.

By adopting the above technical solution, the central axis of the rotational connection position between the transmission frame and the support frame and the central axis of the driving gear are the same central axis, and the installation position of the driving gear is staggered with the positioning block.

By adopting the above technical solution, the support frame will rotate around the central axis of the connection position between the support frame and the transmission frame, thereby ensuring that the support frame can rotate smoothly.

The present invention is further configured such that a limiting groove for sliding the sliding rack is provided in the installation frame, and the length of the limiting groove is greater than the length of the sliding rack, and the number of teeth of the sliding rack is only sufficient for the driving gear to rotate 45°.

By adopting the above technical solution, under the action of the limiting groove, it is ensured that there is enough space in the mounting frame for the sliding rack to slide when the subsequent support frame is reset, thereby preventing the sliding rack and the driving gear from getting stuck.

The present invention is further configured such that when the support frame is not rotating, the outer wall of the reinforcement frame does not contact the outer wall close to the slide rail, and a plurality of groups of buffer wheels are installed at equal intervals on the outer wall of the reinforcement frame close to the slide rail, and a torsion spring corresponding to the movable plate is installed in the end of the reinforcement frame, so that the movable plate and the reinforcement frame are perpendicular to each other.

By adopting the above technical solution, the pressure on the driving gear and the sliding rack is further reduced, and at the same time, the fixedness of the angle of the support frame after rotation is further ensured.

The present invention is further configured such that the installation position of the stopper is staggered from the position of the reinforcement frame, and when the end of the reinforcement frame contacts the top of the slide rail, the side wall of the movable plate contacts the side wall of the stopper.

By adopting the above technical solution, the angle of the reinforcement frame will start to change as the support frame is reset, ensuring that the support of the support frame by the reinforcement frame can be smoothly released.

The present invention also provides a method for using a dust removal device for electronic components, and the method comprises the following steps:

S1: First, pull the handle outward to increase the distance between the two clamps. Then place the circuit board on the supporting wheel and release the handle so that the clamps can clamp and fix the circuit board.

S2: Then, the electric push rod is started, so that the support frame starts to slide into the machine body, thereby;

S3: During the rotation of the support frame, the reinforcement frame will rotate toward the stopper position. When the support frame rotates 45°, the end of the reinforcement frame will collide with the top of the slide rail. At this time, the reinforcement frame will cooperate with the slide rail to support the support frame.

S4: Then, the ion fan and the vacuum cleaner are started, the ion fan starts to blow away the dust on the surface of the circuit board inclined at 45 degrees, and the vacuum cleaner simultaneously sucks away the dust blown away by the ion fan;

S5: After the cleaning is completed, the electric push rod drives the support frame to start resetting. At this time, the driving gear will drive the support frame to start rotating in the opposite direction under the action of the sliding rack, so that the support frame returns to the starting state. At this time, the handle can be pulled outward to remove the circuit board and replace the next circuit board for cyclic processing.

In summary, the present invention mainly has the following beneficial effects:

1. The present invention is provided with a driving gear and a sliding rack, so that when the support frame drives the driving gear to enter the body, the driving gear will drive the support frame to rotate under the action of the sliding rack, causing the circuit board to tilt 45 degrees, so that the wind can better blow away the dust on the surface of the circuit board, effectively reducing the probability of accidents in which the dust remains in the concave and convex parts of the circuit board and cannot be blown away due to the fact that the air outlet of the ion fan is perpendicular to the circuit board, so that the present invention has a better cleaning effect on the circuit board.

2. The present invention is provided with a reinforcement block. Since the reinforcement frame is installed on the outer wall of the support frame close to the outer side of the machine body, when the support frame rotates, the end of the reinforcement frame will rotate relative to the support frame, so that after the driving gear rotates 45°, the reinforcement frame will be perpendicular to the slide rail. At this time, the end of the reinforcement frame will conflict with the top of the slide rail, so that the end of the support frame will be supported by the reinforcement frame and the slide rail, further reducing the pressure on the driving gear and the sliding rack, and at the same time further ensuring the fixity of the angle of the support frame after rotation.

3. The present invention is provided with a movable plate, a torsion spring and a stopper. Under the action of the torsion spring, the movable plate and the reinforcement frame are perpendicular to each other, so that when the support frame slides to the outside of the machine body, the reinforcement frame starts to rotate under the action of the stopper and the movable plate, ensuring that the support of the support frame by the reinforcement frame can be smoothly released and the support frame can be smoothly reset.

4. The present invention provides an installation frame and a limit groove so that the sliding rack can slide smoothly in the installation frame, so that when the support frame slides to the outside of the machine body, the sliding rack and the driving gear will not be stuck, ensuring that there is enough space in the installation frame for the sliding rack to slide when the support frame is subsequently reset, further ensuring that the support frame can be reset smoothly.

5. The present invention is provided with a long groove, and because the width of the long groove is greater than 20MM, the operator's fingers can be smoothly inserted into the long groove to take the circuit board, which is convenient for the operator to remove the circuit board.

6. The present invention is provided with a support assembly, so that when it is necessary to place a circuit board, only a handle needs to be pulled to increase the distance between the two clamping blocks, thereby making it convenient for the operator to place and take the circuit board. At the same time, due to the installation position of the transmission rack and the support wheel, the transmission rack will not directly contact the circuit board, thereby preventing the transmission rack from causing damage to the circuit board.

DETAILED DESCRIPTION

The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

The following describes an embodiment of the present invention based on its overall structure.

A dust removal device for electronic components, as shown in FIGS. 1 to 13 , comprises a body 1 , an inspection door 101 , a circuit board 103 , an ion fan 2 and a dust collector 3 .

Specifically, a support plate 102 is installed on the outer wall of the body 1, and a support frame 6 is arranged on the top of the support plate 102, and a pulley 5 is installed on the outer wall of the support frame 6, and a slide rail 4 for guiding the pulley 5 is installed on the top of the support plate 102. The end of the slide rail 4 is located in the body 1, and the length of the slide rail 4 located in the body 1 is greater than its length located on the top of the support plate 102, so that the pulley 5 can move in the slide rail 4, and the pulley 5 will cooperate with the slide rail 4 to limit the sliding of the support frame 6, ensuring that the support frame 6 can In order to slide smoothly into the machine body 1, a transmission frame 61 is rotatably installed on the outer wall of the support frame 6, so that when the support frame 6 rotates subsequently, the transmission frame 61 will not rotate with it, ensuring that the transmission frame 61 can still slide smoothly when the support frame 6 rotates, and an electric push rod 62 connected to the transmission frame 61 is installed on the top of the support plate 102. When the electric push rod 62 is started, it will push the support frame 6 to slide through the transmission frame 61, ensuring that the support frame 6 can smoothly enter the machine body 1.

Specifically, the pull rod 7 is slidably mounted on the outer wall of the support frame 6, and a clamping block 8 for squeezing the circuit board 103 is installed at the end of the pull rod 7. By pulling the pull rod 7, the spacing between the clamping blocks 8 can be adjusted, so that the spacing between the clamping blocks 8 can be adjusted according to the width of the circuit board 103 to be clamped, and the outer wall of the pull rod 7 is sleeved with a spring 9 connected to the clamping block 8 and the support frame 6, so that when the pull rod 7 drives the clamping block 8 to move outward, the clamping block 8 will squeeze the spring 9, so that the subsequent spring 9 can give the clamping block 8 a force to squeeze the circuit board 103, and a supporting component for supporting the circuit board 103 is provided on the top of the support frame 6, so that when the circuit board 103 is placed between the clamping blocks 8, the supporting component will support the circuit board 103 to ensure that the circuit board 103 can be smoothly squeezed and fixed by the clamping block 8 later.

Specifically, the driving gear 10 is fixedly mounted on the outer wall of the support frame 6, so that when the support frame 6 slides, it drives the gear 10 to move synchronously. At the same time, because the driving gear 10 and the support frame 6 are fixedly connected, when the driving gear 10 rotates, it drives the support frame 6 to rotate synchronously. A mounting frame 11 is fixedly mounted in the body 1, and a sliding rack 12 corresponding to the driving gear 10 is slidably mounted in the mounting frame 11, so that when the support frame 6 drives the driving gear 10 to enter the body 1, the driving gear 10 gradually contacts the sliding rack 12. A limiting groove 13 for sliding the sliding rack 12 is provided in the mounting frame 11. Because the resistance between the sliding rack 12 and the limiting groove 13 is relatively small, and the limiting groove 13 The length of is greater than the length of the sliding rack 12, so that the sliding rack 12 at this time will be pushed by the driving gear 10 until the sliding rack 12 can no longer slide, but the support frame 6 is still sliding into the body 1 at this time, so that the driving gear 10 will start to drive the support frame 6 to rotate under the action of the sliding rack 12. Because the number of teeth of the sliding rack 12 is only enough for the driving gear 10 to rotate 45°, the support frame 6 will rotate 45° under the action of the driving gear 10, so that the circuit board 103 is in an inclined state at this time, so that when the ion fan 2 blows air to the circuit board 103, the wind will first contact the surface of the circuit board 103 to blow away the dust on its surface and the concave and convex parts, and at the same time, the wind will also be guided by the circuit board 103 to the suction The circuit board 103 is blown away in the direction of the dust collector 3. At the same time, because the circuit board 103 is in an inclined state at this time, the wind can better blow away the dust on the surface of the circuit board 103, effectively reducing the probability of accidents in which the dust remains in the concave and convex parts of the circuit board 103 and cannot be blown away due to the fact that the air outlet of the ion fan 2 is perpendicular to the circuit board 103, so that the present invention has a better cleaning effect on the circuit board 103. The body 1 is equipped with a reinforcing block 15 for supporting the end of the support frame 6, so that when the support frame 6 is tilted at 45°, the reinforcing block 15 at this time will limit and support the end of the support frame 6, and the outer wall of the reinforcing block 15 is equipped with a positioning block 14 for limiting the pulley 5, so that when the driving gear 10 is in contact with the sliding rack 12, the pulley 5 has After entering between the positioning block 14 and the slide rail 4, when the subsequent driving gear 10 is meshed with the sliding rack 12, the positioning block 14 will cooperate with the slide rail 4 to limit the position of the pulley 5, so that the pulley 5 will not move upward at this time, ensuring that the support frame 6 can rotate smoothly. At the same time, the end corners of the positioning block 14 are designed with an angle, so that when the pulley 5 enters between the positioning block 14 and the slide rail 4, the angle of the positioning block 14 will prevent the pulley 5 from colliding with the positioning block 14, and the accident that cannot enter between the positioning block 14 and the slide rail 4 will occur. In addition, the reinforcement block 15 is fixedly connected to the slide rail 4, so that the slide rail 4 and the reinforcement block 15 support each other, further improving the connection fixity between the slide rail 4 and the reinforcement block 15 and the body 1.

Specifically, the reinforcement frame 16 is rotatably mounted on the outer wall of the support frame 6. Because the reinforcement frame 16 is mounted on the outer wall of the support frame 6 close to the outer side of the body 1, when the support frame 6 rotates, the end of the reinforcement frame 16 will move synchronously with the support frame 6, but the other end of the reinforcement frame 16 is not restricted, so that this end of the reinforcement frame 16 will rotate relative to the support frame 6, so that after the driving gear 10 rotates 45°, the reinforcement frame 16 will be perpendicular to the slide rail 4, and the end of the reinforcement frame 16 will be at the top of the slide rail 4. The ends of the support frame 6 are supported by the reinforcement frame 16 and the slide rail 4, further reducing the pressure on the driving gear 10 and the sliding rack 12, and further ensuring the stability of the angle of the support frame 6 after the rotation. A movable plate 17 is movably installed at the end of the reinforcement frame 16, and a stopper 18 for contacting the movable plate 17 is installed on the top of the slide rail 4. The installation position of the stopper 18 is staggered with the position of the reinforcement frame 16, so that when the support frame 6 drives the reinforcement frame 16 to slide into the body 1, the stopper 18 can be used to stop the movable plate 17. The block 18 will not affect the sliding of the reinforcement frame 16, and when the end of the reinforcement frame 16 conflicts with the top of the slide rail 4, the side wall of the movable plate 17 will contact the side wall of the stopper 18, so that when the subsequent electric push rod 62 pulls the support frame 6 to reset, the reinforcement frame 16 is in a state of supporting the support frame 6 at this time, so that the support frame 6 cannot rotate in the original direction, so that the support frame 6 at this time will drive the sliding rack 12 to slide through the driving gear 10, so that when the support frame 6 slides out of the body 1, It will also drive the reinforcement frame 16 to move synchronously, but because the movable plate 17 is blocked by the block 18 at this time, the angle of the reinforcement frame 16 begins to change, causing the reinforcement frame 16 to release its support for the support frame 6, ensuring that the support frame 6 can be smoothly reset. At this time, the support frame 6 continues to slide, and the driving gear 10 starts to drive the support frame 6 to rotate under the action of the sliding rack 12, causing the support frame 6 to rotate back to its original position. At this time, the reinforcement frame 16 will also return to its initial state, which is convenient for subsequent continued use.

Please refer to Figure 3. Two groups of ion fans 2 and vacuum cleaners 3 are provided in the body 1, and the two groups of ion fans 2 are respectively located above and below the slide rail 4, so that after the ion fans 2 are started, the upper and lower surfaces of the circuit board 103 are cleaned to prevent the dust from falling to the bottom surface of the circuit board 103 when the dust on the top surface of the circuit board 103 is blown away, and the vacuum cleaners 3 are installed on the side walls of the ion fans 2. The vacuum cleaners 3 are all inclined to ensure that the dust blown away by the ion fans 2 can be smoothly sucked away by the vacuum cleaners 3.

Please refer to Figures 1, 3 and 4. The support frame 6 is designed in a "sun" shape, so that the middle part of the support frame 6 is hollowed out, which is convenient for the subsequent ion fan 2 to clean the bottom of the circuit board 103 and the support assembly, and prevent a large amount of dust from adhering to the bottom of the circuit board 103 and the support assembly. Two groups of pull rods 7 are slidably installed on the outer walls of both sides of the support frame 6, and handles 71 are installed on the outer walls of the pull rods 7. Through the setting of the handles 71, when the spacing between the clamping blocks 8 needs to be adjusted, the handles 71 can be pulled. At the same time, the position where the support frame 6 and the pull rod 7 are slidably connected is provided with damping, so that the pull rod 7 will not slide quickly, thereby preventing the pull rod 7 from sliding too fast and causing the clamping block 8 to damage the circuit board 103.

Please refer to Figures 3 to 6. The support assembly consists of a transmission gear 63, a transmission rack 64, a limit rod 65 and a support wheel 66. The transmission gear 63 shaft is installed at the top of the middle part of the support frame 6, and the transmission rack 64 is fixedly installed at the bottom of the clamping block 8, so that any one of the clamping block 8 and the transmission rack 64 will drive the other to move synchronously when moving, and the transmission rack 64 is meshed with the transmission gear 63, so that the transmission rack 64 will cause the transmission gear 63 to start rotating during the sliding process. At the same time, because the two sets of transmission racks 64 are respectively located on both sides of the transmission gear 63, when one transmission rack 64 slides, it will be in the action of the transmission gear 63 Under the action of the transmission gear 63, the transmission rack 64 and the limiting rod 65, the sliding connection with the transmission rack 64 is installed at the bottom of the clamping block 8, so that the end of the transmission rack 64 is supported by the limiting rod 65 when sliding, thereby reducing the pressure on the connection position between the transmission rack 64 and the clamping block 8 and extending the service life of the transmission rack 64. At the same time, under the action of the transmission gear 63, the transmission rack 64 and the limiting rod 65, the sliding speed of the pull rod 7 can be further reduced, further preventing the pull rod 7 from sliding too fast and causing the clamping block 8 to damage the circuit board 103.

Please refer to Figures 3 to 6. A plurality of groups of support wheels 66 for supporting the circuit board 103 are evenly spacedly installed on the top of the transmission rack 64, so that when the circuit board 103 is placed, it is placed on the top of the support wheel 66. At the same time, when the transmission rack 64 slides, the support wheel 66 will rotate at the bottom of the circuit board 103, thereby reducing the damage to the circuit board 103 caused by the transmission rack 64 when sliding, and the horizontal plane at the top of the transmission rack 64 is lower than the horizontal plane at the bottom of the clamping block 8, so that the transmission rack 64 will not directly contact the circuit board 103, thereby preventing the transmission rack 64 from causing damage to the circuit board 103, and the top of the support wheel 66 and the bottom of the clamping block 8 are located at the same horizontal plane, ensuring that the support wheel 66 can smoothly support the circuit board 103.

Please refer to Figures 3, 4 and 7 to 11. The central axis of the rotational connection position between the transmission frame 61 and the support frame 6 and the central axis of the driving gear 10 are the same central axis, so that when the driving gear 10 drives the support frame 6 to rotate, the support frame 6 will rotate around the central axis of the connection position between it and the transmission frame 61, thereby ensuring that the support frame 6 can rotate smoothly, and the installation position of the driving gear 10 is staggered with the positioning block 14, so that when the driving gear 10 moves with the support frame 6, it will not collide with the positioning block 14, thereby ensuring that the support frame 6 can slide smoothly.

Please refer to Figure - Figure. When the support frame 6 is not rotated, the outer wall of the reinforcement frame 16 does not contact the outer wall close to the slide rail 4, so that the reinforcement frame 16 at this time will not cause wear between the slide rail 4, and multiple sets of buffer wheels 161 are evenly installed on the outer wall of the reinforcement frame 16 close to the slide rail 4. The multiple sets of buffer wheels 161 will contact the slide rail 4, so that the reinforcement frame 16 is supported by the buffer wheels 161, ensuring the fixed angle of the reinforcement frame 16 when it rotates, and a torsion spring corresponding to the movable plate 17 is installed in the end of the reinforcement frame 16, so that the movable plate 17 and the reinforcement frame 16 are perpendicular to each other. When the angle of the movable plate 17 changes, the torsion spring will be pulled or squeezed, so that when the movable plate 17 loses its restriction, the torsion spring will push the movable plate 17 back to its original position, thereby ensuring that when the subsequent reinforcement frame 16 is perpendicular to the slide rail 4, the outer wall of the movable plate 17 will contact the stopper 18.

Please refer to Figures 3 and 4. A long groove 67 is formed on the top of the outer wall of the support frame 6 away from the body 1, and the width of the long groove 67 is greater than 20MM, so that the operator's fingers can be smoothly inserted into the long groove 67 to take the circuit board 103, making it convenient for the operator to remove the circuit board 103.

The present invention also provides a method for using a dust removal device for electronic components, as shown in FIGS. 1 to 13 , the process includes the following steps:

S1: First, pull the handle 71 outward, which will drive the pull rod 7 and the clamping block 8 to slide outward. At this time, the clamping block 8 will drive the transmission rack 64 to move synchronously, so that the transmission gear 63 starts to rotate, causing another set of transmission racks 64 to slide synchronously, thereby increasing the distance between the two clamping blocks 8. At this time, place the circuit board 103 above the supporting wheel 66, and then release the handle 71. At this time, the spring 9 will use its own characteristics to push the clamping block 8 to its original position, so that the clamping block 8 clamps the circuit board 103;

S2: Then, the electric push rod 62 is started, which drives the support frame 6 to slide into the body 1 through the transmission frame 61. At this time, the support frame 6 drives the driving gear 10 to move synchronously, so that the driving gear 10 contacts the sliding rack 12. As the support frame 6 continues to slide, the sliding rack 12 conflicts with the limiting groove 13. At this time, the support frame 6 continues to slide into the body 1, so that the driving gear 10 drives the support frame 6 to rotate under the action of the sliding rack 12, causing the circuit board 103 to tilt 45°;

S3: During the rotation of the support frame 6, the reinforcement frame 16 will rotate toward the position of the stopper 18. After the support frame 6 rotates 45°, the reinforcement frame 16 will also rotate to a state perpendicular to the slide rail 4. At the same time, the end of the reinforcement frame 16 will contact the top of the slide rail 4. At this time, the reinforcement frame 16 will cooperate with the slide rail 4 to support the support frame 6, thereby improving the fixity of the angle of the support frame 6 after rotation;

S4: Then, the ion fan 2 and the vacuum cleaner 3 are started, and the ion fan 2 starts to blow away the dust on the surface of the circuit board 103 which is tilted at 45 degrees. Since the circuit board 103 is in a tilted state, the wind can better blow away the dust on the surface of the circuit board 103, effectively reducing the probability of accidents that the dust always remains in the concave and convex parts of the circuit board 103 and cannot be blown away because the air outlet of the ion fan 2 is perpendicular to the circuit board 103, so that the present invention has a better cleaning effect on the circuit board 103, and at the same time, the vacuum cleaner 3 will simultaneously suck away the dust blown away by the ion fan 2;

S5: After the cleaning is completed, the electric push rod 62 drives the support frame 6 to start to reset. At this time, the reinforcement frame 16 is in a state of supporting the support frame 6, so that the support frame 6 cannot rotate in the original direction, so that the support frame 6 at this time will drive the sliding rack 12 to slide through the driving gear 10. At this time, the movable plate 17 is blocked by the block 18, so that the angle of the reinforcement frame 16 begins to change, causing the support of the support frame 6 by the reinforcement frame 16 to be released. At this time, the driving gear 10 will drive the support frame 6 to start rotating in the opposite direction under the action of the sliding rack 12, so that the support frame 6 returns to the starting state until the support frame 6 slides out of the body 1. At this time, the handle 71 can be pulled outward to remove the circuit board 103 and replace it with the next circuit board 103 for cyclic processing.
