[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7As shown, a conveying device for PCB board production includes a support 1. A front plate 2 is fixedly connected to the top front side of the support 1, and a rear plate 3 is slidably connected to the top rear side of the support 1. A swing mechanism is provided on the rear side of the front plate 2. The swing mechanism includes two driven rollers 601, which are rotatably connected to the rear side of the front plate 2. A swing arm 602 is fixedly connected to the rear side of the lower driven roller 601, and a slider 603 is rotatably connected to the rear side of the swing arm 602. A limit frame 604 is slidably connected to the slider 603. Two extension rods 605 are fixedly connected to the front side of the limit frame 604, and the front ends of the extension rods 605 are slidably connected to the front plate 2. The driven rollers are driven by a second conveyor belt 405. When roller 601 rotates, the driven roller 601 rotates, which drives the swing arm 602 to rotate. The rotation of the swing arm 602 drives the slider 603 to rotate. The rotation of the slider 603 drives the limiting frame 604 to reciprocate on the rear side of the front plate 2. The front plate 2 is provided with a driving mechanism, which is used to drive the swing mechanism to swing. The rear top of the bracket 1 is provided with an adjustment mechanism. The rear side of the front plate 2 is provided with a sliding mechanism. The driving mechanism is used to drive the sliding mechanism to move. The sliding mechanism is provided with a ventilation mechanism and a flow guiding mechanism. The opposing surfaces of the front plate 2 and the rear plate 3 are fixedly connected with pressure plates 10. The rear side of the front plate 2 is fixedly connected with two guide rods 11. The rear plate 3 is slidably connected to the guide rods 11.

[0028] The drive mechanism includes a motor 401, which is fixedly connected to the front side of the front plate 2. The output end of the motor 401 is fixedly connected to a rotating shaft 402, which is rotatably connected to the front plate 2 and the rear plate 3. Two retaining sleeves 403 are rotatably connected to the opposite surfaces of the front plate 2 and the rear plate 3. The rotating shaft 402 engages with one retaining sleeve 403. A second conveyor belt 405 is connected to the front retaining sleeve 403, and a first conveyor belt 404 is connected to the rear retaining sleeve 403. When the motor 401 is started, the motor 401 drives the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives the retaining sleeve 403 on one side to rotate. The rotation of the retaining sleeve 403 drives the first conveyor belt 404 and the second conveyor belt 405 to drive each other. The first conveyor belt 404 and the second conveyor belt 405 drive the retaining sleeve 403 on the other side to rotate.

[0029] The adjustment mechanism includes a fixed frame 501, which is fixedly connected to the top rear side of the support 1. A worm gear 502 is rotatably connected to the top of the fixed frame 501, and the bottom of the worm gear 502 is rotatably connected to the top of the support 1. A rocker arm 503 is fixedly connected to the top of the worm gear 502. A worm wheel 504 is engaged on the side of the worm gear 502 near the center of the support 1. A threaded rod 505 is fixedly connected to the worm wheel 504. The threaded rod 505 is rotatably connected to the front plate 2 and threadedly connected to the rear plate 3. Rotating the rocker arm 503 causes the worm gear 502 to rotate, which in turn causes the worm wheel 504 to rotate, which in turn causes the threaded rod 505 to rotate. The rotation of the threaded rod 505 can move the rear plate 3 on the top of the support 1 to adjust the distance between the rear plate 3 and the front plate 2 to accommodate PCBs of different sizes.

[0030] The sliding mechanism includes several fixed posts 701, which are fixedly connected to the rear side of the front plate 2. A bellows 702 is fixedly connected to the rear side of the fixed posts 701. A push rod 703 is slidably connected to one side of the bellows 702. One end of the push rod 703 near the swing mechanism is fixedly connected to the limiting frame 604. The other end of the push rod 703 is fixedly connected to the sliding plate 704. The reciprocating movement of the limiting frame 604 drives the push rod 703 and the sliding plate 704 to reciprocate.

[0031] The ventilation mechanism includes two cover plates 801, which are hinged to the inner walls of the air box 702. A coil spring is built into the hinge. Through holes 802 are provided on both sides of the air box 702. A partition plate 803 is fixedly connected to the inner surface of the air box 702. A guide groove 804 is provided on both sides of the top of the partition plate 803. When the slide plate 704 moves outward, the inner cover plate 801 will be lifted due to the negative pressure box inside the air box 702, so that the inside of the air box 702 is connected to the outside air through the through hole 802. At this time, another part of the air will form an airflow and flow downward through the outer guide groove 804.

[0032] The airflow guiding mechanism includes a guide plate 901, which is fixedly connected to the bottom of the inner wall of the air box 702. A baffle 902 is rotatably connected to the rear side of the guide plate 901. A collection cover 903 is fixedly connected to the front side of the air box 702. A ventilation pipe 904 is fixedly connected to the front side of the collection cover 903. A guide pipe 905 is fixedly connected to the ventilation pipe 904. Several nozzles 906 are fixedly connected to the rear side of the guide pipe 905. The airflow flows towards the collection cover 903 under the action of the guide plate 901. Under the action of the airflow, the baffle 902 is pushed to the other side, so that the airflow passes through the collection cover 903 and flows into the ventilation pipe 904. When the slide plate 704 moves inward, the other side will repeat the process, so that the ventilation pipe 904 always keeps the airflow flowing. The air in the ventilation pipe 904 passes through the guide pipe 905 and is finally sprayed out through the nozzles 906 to blow away the surface and bottom of the PCB board, so as to prevent the surface from being contaminated with dust and affecting its subsequent use.

[0033] Working principle: When using this device, the operator first rotates the rocker arm 503. The rotation of the rocker arm 503 drives the worm gear 502 to rotate, which in turn drives the worm wheel 504 to rotate. The rotation of the worm wheel 504 drives the threaded rod 505 to rotate. The rotation of the threaded rod 505 can move the rear plate 3 on top of the bracket 1 to adjust the distance between the rear plate 3 and the front plate 2 to accommodate PCBs of different sizes.

[0034] The motor 401 is started, which drives the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives the ferrule 403 on one side to rotate. The rotation of the ferrule 403 drives the first conveyor belt 404 and the second conveyor belt 405 to rotate. The first conveyor belt 404 and the second conveyor belt 405 drive the ferrule 403 on the other side to rotate. Then, the PCB board is placed on the surface of the first conveyor belt 404 and the second conveyor belt 405 near the motor 401. The PCB board will be conveyed in the conveying direction of the first conveyor belt 404 and the second conveyor belt 405. When the PCB board moves to the bottom of the pressure plate 10, its top will be squeezed by the pressure plate 10 to maintain the stability of the PCB board during the conveying process.

[0035] The second conveyor belt 405 drives two driven rollers 601 to rotate. The rotation of the lower driven roller 601 drives the swing arm 602 to rotate, which in turn drives the slider 603 to rotate. The rotation of the slider 603 drives the limiting frame 604 to reciprocate on the rear side of the front plate 2. The reciprocating movement of the limiting frame 604 drives the push rod 703 and the slide plate 704 to reciprocate. When the slide plate 704 moves outward, the inner cover plate 801 will be lifted inward due to the negative pressure inside the bellows 702, allowing the interior of the bellows 702 to communicate with the outside air through the through hole 802. At this time, another part of the air will form gas. The airflow flows downward through the outer guide groove 804. Under the action of the guide plate 901, the airflow flows towards the collection cover 903. Under the action of the airflow, the baffle 902 is pushed to the other side, so that the airflow flows through the collection cover 903 into the ventilation pipe 904. When the slide plate 704 moves inward, the other side will repeat the process, so that the ventilation pipe 904 always keeps the air flowing. The air in the ventilation pipe 904 passes through the guide pipe 905 and is finally sprayed out through the nozzle 906 to blow away the surface and bottom of the PCB board, so as to prevent the surface from being contaminated with dust and affecting its subsequent use.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
