Description

Technical Field

[0001] This utility model relates to the field of PCB board drying machine technology, and more specifically, to a PCB board processing drying machine. Background Technology

[0002] In PCB board processing, in order to eliminate internal stress, improve dimensional stability, and remove moisture, a drying machine is needed to dry the PCB board. For example, a PCB board drying machine with patent publication number CN215373280U includes a box body with a strip-shaped through hole on the top of the box body. A slide groove is provided above the strip-shaped through hole, and a slider is provided on the slide groove. A motor is bolted to the bottom of the slider through the strip-shaped through hole. The output shaft of the motor is welded to a housing. A placement box is provided inside the housing, and a separation plate is welded inside the placement box. A hydraulic cylinder is bolted to the top of the box body. The piston end of the hydraulic cylinder is welded to one side of the slider. A drying device is provided inside the box body. A gas collection hood is welded to one side of the inside of the box body. An exhaust fan is fixed inside the gas collection hood, and an air duct is connected to one end of the gas collection hood that passes through the box body. Compared with the prior art, the advantages of this utility model are as follows: it is equipped with a multi-layer placement box, which can dry PCB boards in batches; the placement box is equipped with a separation plate, which separates the PCB boards from each other during drying to avoid contact and damage; the hollow mesh structure makes the drying effect more uniform; and an exhaust fan is provided to prevent the harm of exhaust gas.

[0003] However, after the PCB board is dried, it retains a certain temperature due to the drying process. If personnel remove it manually, they may suffer burns because the internal temperature has not yet dropped. Furthermore, the PCB board needs to cool down on its own after drying. If the PCB board is removed from the equipment while waiting for its temperature to drop, the overall drying efficiency will be affected. Therefore, we have made an improvement and proposed a PCB board processing drying machine that can automatically store and retrieve PCB boards, thereby improving the efficiency during continuous drying. Utility Model Content

[0004] The main purpose of this utility model is to provide a PCB board drying machine that can effectively solve the problem that the PCB board cannot be quickly removed manually after drying due to the high temperature.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A PCB board processing drying machine includes a support frame, a lower platform fixedly mounted on the upper end of the support frame, connecting components on both sides of the lower platform, and an upper platform connected to both sides of the lower platform via the connecting components.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 7 As shown, a PCB board processing drying machine includes a support 1. A lower platform 2 is fixedly installed on the upper end of the support 1. Connecting components 7 are provided on both sides of the lower platform 2. An upper platform 3 is connected to both sides of the lower platform 2 through the connecting components 7. A heating component 4 for drying PCB boards is provided on the surface of both the lower platform 2 and the upper platform 3. A feeding component 5 for storing and retrieving boards is fixedly installed on one side of the lower platform 2. An air guide component 6 for discharging internal moisture is fixedly installed on one side of the upper platform 3.

[0026] In this embodiment, the connecting component 7 includes a connecting socket 703 and a connecting plate 704. The connecting socket 703 is fixedly installed on both sides of the lower platform 2, and the connecting plate 704 is fixedly installed on both sides of the upper platform 3. The connecting socket 703 and the connecting plate 704 are movably connected. A fixing plate 701 is fixedly installed on one side of both the lower platform 2 and the upper platform 3, and a cylinder 702 is fixedly installed between the two fixing plates 701.

[0027] By activating cylinder 702, the upper fixing plate 701 can be pushed. The two fixing plates 701 are connected to the lower platform 2 and the upper platform 3 respectively. The interlocking cooperation between the connecting socket 703 and the connecting plate 704 allows the distance between the lower platform 2 and the upper platform 3 to be adjusted, ensuring that this application can be applied to PCB boards of different thicknesses. In order to ensure the drying effect, the connection between the connecting socket 703 and the connecting plate 704 can seal both sides of this application, ensuring that heat does not dissipate quickly and thus ensuring the drying effect.

[0028] In this embodiment, the heating component 4 includes a guide cover 402, which is respectively disposed on the upper and lower surfaces of the lower platform 2 and the upper platform 3. A plurality of heat exhaust holes 401 are opened through the surfaces of the lower platform 2 and the upper platform 3. A branch pipe 404 is fixedly installed at the center of the guide cover 402 through a connecting seat 403. The two branch pipes 404 are interconnected and are connected to a heat receiving pipe 405 for receiving hot air.

[0029] By connecting the heat pipe 405 to the hot air equipment, heat can be guided into the two branch pipes 404, and then delivered to the corresponding guide covers 402 under the action of the branch pipes 404. Finally, hot air will be discharged from several heat exhaust holes 401 into the space between the lower platform 2 and the upper platform 3 to achieve the drying and heating of the PCB board.

[0030] In this embodiment, the air guide assembly 6 includes an extension frame 601, which is fixedly installed on one side of the upper platform 3. An exhaust rotating rod 603 is rotatably installed inside the extension frame 601. An air guide cover 602 for guiding the exhaust airflow is fixedly installed on the upper end of the extension frame 601. A second motor 604 is fixedly installed on one side of the extension frame 601, and the output end of the second motor 604 is fixedly connected to the exhaust rotating rod 603.

[0031] To prevent moisture generated during PCB drying from remaining in the heating cavity, the second motor 604 drives the exhaust fan rod 603 to rotate continuously. The rotation of the exhaust fan rod 603 then discharges the residual moisture in the heating cavity to one side, achieving real-time heat dissipation and preventing excessive moisture inside the heating cavity from affecting the quality of the PCB.

[0032] In this embodiment, the feeding component 5 includes a chute 502, which is opened on one side of the lower platform 2. Two moving rods 503 are slidably installed inside the chute 502, and a fixed baffle 508 is fixedly installed between the two moving rods 503. One of the moving rods 503 has an adjustment groove 509 on its shaft, and a moving baffle 507 is slidably installed inside the adjustment groove 509.

[0033] A mounting base 505 is fixedly installed on one side of the lower platform 2. A drive gear 506 is rotatably installed inside the mounting base 505. Several toothed grooves 504 are opened at the bottom of one of the moving rods 503. The toothed grooves 504 mesh with the drive gear 506. A first motor 501 is fixedly installed on the outside of the mounting base 505. The output end of the first motor 501 is fixedly connected to the drive gear 506.

[0034] By starting the first motor 501, the drive gear 506 can be driven to rotate inside the mounting base 505. Utilizing the sliding engagement between the moving rod 503 and the slide groove 502, the moving rod 503 is moved in position under the meshing of the toothed groove 504 and the drive gear 506, causing the PCB board placed above the moving rod 503 to move accordingly. By utilizing the meshing of the toothed groove 504 and the drive gear 506, the moving rod 503 can move back and forth in two directions, thereby automatically removing the PCB board after drying. This avoids the PCB board being burned by excessively high temperatures after drying. Furthermore, by automatically storing and retrieving the PCB board, efficient continuous drying operations can be achieved.

[0035] To prevent the PCB board from falling off during storage and retrieval, a fixed baffle 508 is fixedly installed on one side of the moving rod 503, and a moving baffle 507 is slidably installed inside one of the moving rods 503. By adjusting the position of the moving baffle 507, the distance between the moving baffle 507 and the fixed baffle 508 can be adjusted, thus enabling stable storage and retrieval of PCB boards of different sizes.

[0036] The working principle of this PCB board processing and baking machine:

[0037] In use, the PCB board is placed above the moving rod 503. Then, the position of the moving baffle 507 is adjusted according to the size of the PCB board so that the moving baffle 507 and the fixed baffle 508 can stabilize the position of the PCB board. After completion, the first motor 501 is started, which can drive the drive gear 506 to rotate inside the mounting base 505. Utilizing the sliding cooperation between the moving rod 503 and the slide groove 502, the moving rod 503 is moved in position under the meshing of the tooth groove 504 and the drive gear 506, and the PCB board placed above the moving rod 503 moves accordingly, so that the PCB board enters between the lower platform 2 and the upper platform 3.

[0038] Then, by connecting the heat pipe 405 to the hot air equipment, heat can be guided into the two branch pipes 404, and then delivered to the corresponding guide cover 402 under the action of the branch pipes 404. Finally, hot air will be discharged from several heat exhaust holes 401 into the space between the lower platform 2 and the upper platform 3 to achieve the drying and heating of the PCB board.

[0039] After the PCB board is heated, the first motor 501 is restarted and rotated in the opposite direction, so that the toothed groove 504 and the drive gear 506 mesh in opposite directions, thereby sending out the PCB board stored above the moving rod 503. There is no need for manual removal from the heating cavity, which ensures the safety of the operator and improves the efficiency of baking the board.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
