Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to a baking plate device for PCB board processing. Background Technology

[0002] PCB circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. In the processing of electronic components, PCB circuit boards need to be sprayed with conformal coating to give them waterproof, moisture-proof, and dustproof properties. Before spraying, the moisture and water on the PCB circuit board need to be removed, which requires the use of a baking device to bake the PCB circuit board.

[0003] Existing technologies, such as Chinese Patent Publication No. CN221010422U, disclose a PCB circuit board baking device for electronic component processing, including a housing. A soft pad is fixedly connected to one outer surface of a movable plate, and a threaded shaft is movably connected to the other outer surface of the movable plate. A handle is fixedly connected to the outer wall of the threaded shaft. The cleaning device includes a housing, a drive shaft, gears, a connecting shaft, a brush head, a fixed plate, and a track. The housing is movably connected to one outer surface of a support frame, and the drive shaft is movably connected to one outer surface of the housing. When using this device, the fixed plate can be installed on one outer surface of the support frame using the cleaning device. When the housing is working, it can drive the drive shaft, gears, and brush head to rotate. The gears and track can prevent positional displacement during rotation, thus preventing damage to the PCB circuit board during cleaning. After the brush head rotates, it can clean the dust on the surface of the PCB circuit board, preventing dust from damaging the components. However, in this invention, the PCB board is in a fixed state during baking, making it difficult for its surface to be fully and evenly heated.

[0004] To address the issue that baking devices for PCB board processing cannot ensure sufficient and uniform heating of the PCB board surface, existing equipment often clamps and fixes the PCB board during baking. However, due to issues with the position, height, and angle of the baking mechanism, the PCB board surface cannot be heated sufficiently and uniformly, potentially leading to overheating damage in some areas or incomplete drying. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing baking plate devices for PCB board processing are not conducive to fully and uniformly heating the surface of the PCB board, and to propose a baking plate device for PCB board processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a baking plate device for PCB board processing, comprising a box, a heating rod, a ventilation slot and a baking mechanism, wherein the heating rod is fixedly installed on the inner wall of the box, the ventilation slot is opened on the inner wall of the box, and the baking mechanism is arranged on the inner wall of the box;

[0007] The baking mechanism includes a placement platform, which is rotatably connected to the inner wall of the box. A motor is fixedly installed on the inner wall of the box. A rotating shaft is fixedly connected to the output end of the motor. The rotating shaft is rotatably connected to the inner wall of the box. A half gear is fixedly connected to the surface of the rotating shaft.

[0008] A guide rod is fixedly connected to the inner wall of the box, a toothed plate is slidably connected to the surface of the guide rod, the half gear meshes with the surface of the toothed plate, a rotating gear is fixedly connected to the surface of the placement platform, the rotating gear meshes with the surface of the toothed plate, a spring is sleeved and connected to the surface of the guide rod, and a fan blade is fixedly connected to the surface of the rotating shaft.

[0009] Furthermore, one end of the spring is fixedly connected to the inner wall of the housing, and the other end of the spring is fixedly connected to the surface of the toothed plate.

[0010] Furthermore, the inner wall of the box is fixedly connected with a partition, and the surface of the box is provided with heat dissipation grooves, which are multiple sets and evenly distributed.

[0011] Furthermore, the number of the placement platform is multiple, the number of the guide rod, the toothed plate and the spring are two, and the surface of the placement platform is fixedly connected to a limiting plate.

[0012] Furthermore, the surface of the placement platform is provided with a clamping mechanism, the clamping mechanism including a slide rod, the slide rod being slidably connected to the inner wall of the placement platform, a clamping plate being fixedly connected to the surface of the slide rod, a second spring being fixedly connected to the surface of the clamping plate, and a push plate being slidably connected to the surface of the placement platform.

[0013] Furthermore, the surface of the push plate is provided with an inclined groove, the clamping plate cooperates with the inclined groove, and a spring three is fixedly connected to the surface of the push plate, and the spring three is fixedly connected to the surface of the placement platform.

[0014] Furthermore, the surface of the placement platform is provided with screw holes, and a screw is threaded onto the surface of the screw holes. The screw cooperates with the push plate, and there are two sets of clamping plates arranged symmetrically.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, by setting up a baking mechanism, the PCB board is placed on the placement platform. The heating rod and motor are started, and the motor drives the rotating shaft to rotate, causing the fan blades to rotate. Hot air is blown onto the PCB board through the heat dissipation groove. At the same time, the rotating shaft causes the half gear to rotate. When the half gear contacts the toothed plate, it drives the toothed plate to slide along the guide rod and press the first spring. When the half gear disengages from the toothed plate, the toothed plate returns to its original position under the rebound action of the first spring, causing the toothed plate to continuously reciprocate. In turn, the rotating gear causes multiple sets of placement platforms to continuously rotate forward and backward, so that the PCB board on it rotates continuously and makes full contact with the hot air. After baking, the above process can be repeated with the heating rod turned off and the chamber opened to quickly cool the PCB board. By setting up a baking mechanism, the rotating fan blades and the continuously forward and reverse placement platforms make the air inside the chamber circulate quickly, and the surface of the PCB board is heated evenly, improving the drying efficiency and facilitating subsequent cooling operations. This effectively improves the convenience of the equipment.

[0017] 2. In this utility model, by setting a clamping mechanism, the PCB board is placed on the placement table, and the screw is rotated to move it along the screw hole towards the push plate, pushing the push plate and tightening the spring three. The inclined groove drives the two sets of clamping plates to move towards each other, causing the slide rod to slide and tighten the spring two. The clamping plates hold the PCB board to prevent it from falling during rotation. When it is necessary to remove the PCB board, simply rotate the screw in the opposite direction to stop pushing the push plate. Under the rebound of the spring three, the push plate returns to its original position. Under the rebound of the spring two, the two sets of clamping plates move in opposite directions, and the PCB board can be removed. By setting a clamping mechanism, the PCB board can be stably clamped to prevent it from falling during rotation baking. Moreover, the disassembly and assembly process is relatively simple and labor-saving, which effectively improves the convenience of the equipment. Attached Figure Description

The heating rod 2 is fixedly installed on the inner wall of the box 1, the ventilation groove 3 is opened on the inner wall of the box 1, and the baking mechanism 4 is arranged on the inner wall of the box 1.

[0026] The specific setup and function of its baking mechanism 4 and clamping mechanism 5 will be explained below.

[0029] The effects achieved by the above components are as follows: the placement platform 401 is set up to place the PCB board; the motor 402, rotating shaft 403, half gear 404, toothed plate 406 and rotating gear 407 are set up so that when the motor 402 is started and the rotating shaft 403 drives the half gear 404 to rotate, the toothed plate 406 will move back and forth along the guide rod 405 in conjunction with the spring 408; the rotating gear 407 will make the placement platform 401 continuously rotate forward and backward, so that the surface of the PCB board is heated evenly; the guide rod 405 is set up to provide guidance and limit for the movement of the toothed plate 406; the fan blade 409 is set up so that when the rotating shaft 403 rotates, it can drive the fan blade 409 to rotate, and in conjunction with the heating rod 2, hot air is blown to the PCB board through the ventilation groove 3.

[0030] Specifically, one end of spring 408 is fixedly connected to the inner wall of housing 1, and the other end of spring 408 is fixedly connected to the surface of toothed plate 406.

[0031] The effect achieved by the above components is as follows: when the half gear 404 contacts the toothed plate 406, it drives the toothed plate 406 to slide along the guide rod 405 and press the spring 408. When the half gear 404 disengages from the toothed plate 406, the toothed plate 406 returns to its original position under the rebound action of the spring 408, so that the toothed plate 406 reciprocates continuously.

[0032] Specifically, the inner wall of the housing 1 is fixedly connected with a partition 410, and the surface of the housing 1 is provided with heat dissipation grooves 411, which are multiple sets and evenly distributed.

[0033] The effect achieved by the above components is that the partition 410 and the heat dissipation slot 411 are set up to place the motor 402 separately to avoid affecting the baking operation, and to facilitate sufficient heat dissipation when it is working.

[0035] The effects achieved by the above components are as follows: setting multiple placement platforms 401 is to facilitate the placement of multiple PCB boards; setting two sets of guide rods 405, toothed plates 406 and springs 408 is to facilitate the continuous forward and reverse rotation of the multiple placement platforms 401 on both sides of the rotating shaft 403; and setting a limiting plate 412 is to cooperate with the rotating gear 407 to limit the placement platform 401, so that it can only perform rotational movement.

[0036] Specifically, the surface of the placement platform 401 is provided with a clamping mechanism 5, which includes a slide rod 51. The slide rod 51 is slidably connected to the inner wall of the placement platform 401. A clamping plate 52 is fixedly connected to the surface of the slide rod 51. A second spring 53 is fixedly connected to the surface of the clamping plate 52. The second spring 53 is fixedly connected to the surface of the placement platform 401. A push plate 54 is slidably connected to the surface of the placement platform 401.

[0037] The effects achieved by the above components are as follows: the slide bar 51 provides guidance and limit for the movement of the clamping plate 52; the clamping plate 52 is set to facilitate the clamping and fixing of the PCB board; the spring 53 is set to utilize its rebound effect to facilitate the reset of the clamping plate 52 so as to remove the PCB board; and the push plate 54 is set to facilitate the pushing of the clamping plate 52.

[0038] Specifically, the surface of the push plate 54 is provided with a slanted groove 55, the clamping plate 52 cooperates with the slanted groove 55, and a spring 3 56 is fixedly connected to the surface of the push plate 54, and the spring 3 56 is fixedly connected to the surface of the placement table 401.

[0039] The effects achieved by the above components are as follows: the inclined groove 55 is provided so that when the push plate 54 moves towards the clamping plate 52, the inclined groove 55 pushes the two sets of clamping plates 52 to move towards each other for clamping; the spring 3 56 is provided so that the push plate 54 can be reset by utilizing its rebound effect.

[0040] Specifically, the surface of the placement platform 401 is provided with screw holes 57, and screws 58 are threadedly connected to the surface of the screw holes 57. The screws 58 cooperate with the push plate 54, and there are two sets of clamping plates 52 arranged symmetrically.

[0041] The effects achieved by the above components are as follows: the screw hole 57 and screw 58 are provided to cooperate with the spring 3 56 to facilitate the movement and fixation of the push plate 54; the two sets of clamping plates 52 are provided to facilitate the clamping and fixing of the PCB board from both sides.

[0042] Working principle: By setting up the baking mechanism 4, the PCB board is placed on the placement platform 401. The heating rod 2 and the motor 402 are started. The motor 402 drives the rotating shaft 403 to rotate, causing the fan blades 409 to rotate. Hot air is blown to the PCB board through the heat dissipation slot 411. At the same time, the rotating shaft 403 causes the half gear 404 to rotate. When the half gear 404 contacts the toothed plate 406, it drives the toothed plate 406 to slide along the guide rod 405 and press the spring 408. When the half gear 404 disengages from the toothed plate 406, the toothed plate 406 returns to its original position under the rebound action of the spring 408. The continuous reciprocating motion, along with the rotating gear 407 causing multiple placement tables 401 to rotate continuously in both directions, ensures the PCB boards on them rotate and come into full contact with the hot air. After baking, the process can be repeated with the heating rod 2 turned off and the chamber 1 opened to rapidly cool the PCB boards. By setting up the baking mechanism 4, the rotating fan blades 409 and the continuously rotating placement tables 401 facilitate rapid air circulation inside the chamber 1, while the PCB board surface is heated evenly, improving drying efficiency and facilitating subsequent cooling operations, thus effectively enhancing the convenience of the equipment.

[0043] Furthermore, by setting up a clamping mechanism 5, the PCB board is placed on the placement table 401. The screw 58 is rotated to move it along the screw hole 57 towards the push plate 54, pushing the push plate 54 and tightening the spring 3 56. The inclined groove 55 drives the two sets of clamping plates 52 to move towards each other, causing the slide bar 51 to slide and tighten the spring 2 53. The clamping plates 52 hold the PCB board in place, preventing it from falling during rotation. When it is necessary to remove the PCB board, simply rotate the screw 58 in the opposite direction to stop pushing the push plate 54. The push plate 54 returns to its original position under the rebound of the spring 3 56, and the two sets of clamping plates 52 move away from each other under the rebound of the spring 2 53, thus removing the PCB board. By setting up the clamping mechanism 5, the PCB board can be stably clamped to prevent it from falling during rotation baking, and the disassembly and assembly process is relatively simple and labor-saving, which effectively improves the convenience of the equipment.
