Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, specifically to a baking plate equipment for PCB boards. Background Technology

[0002] During the PCB manufacturing process, the PCB board needs to be baked. This not only solidifies its surface but also eliminates internal stress and stabilizes its dimensions. For example... Figure 6 As shown, an existing PCB baking machine includes a baking machine 1 and a feeding mechanism. The inclined surface of the baking machine 1 has a feeding port. The feeding mechanism includes a roller feeding module 201, a slide plate 202, a cylinder 203, and a hydraulic cylinder 204. The roller feeding module 201 is fixed in front of the feeding port. The slide plate 202 is connected to the roller feeding module 201. The output end of the hydraulic cylinder 204 is connected to a carrier plate 205. The side of the carrier plate 205 is positioned near the slide plate 202, facing away from the baking machine 1. The output end of the cylinder 203 is connected to a suction cup 206, which is located on the slide plate 202. In the upper part, when the drying equipment is in use, several PCB boards are stacked on the carrier board 205. The cylinder 203 drives the suction cup 206 to descend. After the suction cup 206 adsorbs the PCB board, the cylinder 203 drives the suction cup 206 back to the initial position. Then the suction cup 206 releases the PCB board, and the PCB board will fall to the top of the slide plate 202 due to gravity. Then the PCB board slides along the top of the slide plate 202 until it contacts the roller feeding module 201. Finally, the roller feeding module 201 is activated and pulls the PCB board into the baking machine 1, and the baking machine 1 will perform baking operation on the PCB board.

[0003] However, when the PCB board falls onto the slide plate, the impact force generated by the slide plate can easily damage the surface of the PCB board. In addition, during the process of the roller feeding module pulling the PCB board into the baking machine 1, the surface of the PCB board will rub against the slide plate, which can easily cause wear on the surface of the PCB board. Utility Model Content

[0004] The purpose of this invention is to design a baking sheet device for PCB boards, which can solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PCB baking sheet equipment includes a baking machine and a feeding mechanism. The feeding mechanism includes a roller feeding module, a slide plate, and a cylinder. The roller feeding module is fixed in front of the feeding port of the baking machine. The slide plate is connected to the roller feeding module. The output end of the cylinder is connected to a suction cup, which is located above the slide plate. The top of the slide plate has several grooves evenly distributed along its top length. A hub frame is provided in the grooves. Several pulleys are rotatably connected to the hub frame. The pulleys are evenly distributed along the top width of the slide plate. An elastic buffer mechanism is provided in the grooves and is connected to the bottom of the hub frame.

[0007] Furthermore, the pulley is covered with a rubber pad.

[0008] Furthermore, the elastic buffer mechanism includes a frame, springs, and slide bars. There are two slide bars, and their top ends are fixedly connected to the bottom of the hub frame. The top of the frame is provided with a sliding hole that slides with the slide bars. There are two springs, which are fixedly connected to the bottom ends of the two slide bars respectively. The other end of the spring is fixed to the bottom inside the frame.

[0009] Furthermore, a limiting plate is provided at the bottom end of the slide rod.

[0010] Furthermore, the bottom of the groove is provided with a limiting groove that is adapted to the frame.

[0011] Furthermore, the feeding mechanism also includes a hydraulic cylinder, the output end of which is connected to a carrier plate, and the side of the carrier plate is positioned close to the slide plate and facing away from the baking machine.

[0012] The beneficial effects of this utility model are as follows:

[0013] By setting several hub frames along the length of the top of the skateboard, and rotatably connecting several pulleys evenly distributed along the width of the top of the skateboard, the PCB board can fall onto the pulleys. The elastic buffer mechanism can reduce the impact force of the pulleys on the PCB board and avoid damage to the surface of the PCB board.

[0014] During the process of pulling the PCB board into the baking machine, the roller feeding module reduces the friction between the PCB board and the slide plate through the rolling friction between the PCB board and the pulley, thereby reducing the surface wear of the PCB board.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] like Figure 1-5As shown, a PCB baking sheet equipment includes a baking machine 1 and a feeding mechanism 2. The feeding mechanism 2 includes a roller feeding module 201, a sliding plate 202, a cylinder 203, and a hydraulic cylinder 204. The roller feeding module 201 is fixed in front of the inlet of the baking machine 1. The roller feeding module 201 includes a first roller and a second roller, which are rotatably arranged. The first roller and the second roller cooperate to feed the PCB into the baking machine 1. The sliding plate 202 docks with the roller feeding module 201, and the hydraulic cylinder 204... The output end of the cylinder is connected to a carrier plate 205. The side of the carrier plate 205 is positioned near the slide plate 202, facing away from the baking machine 1. The PCBs to be baked are stacked on the carrier plate 205. The hydraulic cylinder 204 can drive the carrier plate 205 to rise, thereby driving the stacked PCBs to rise. The output end of the cylinder 203 is connected to a suction cup 206. The suction cup 206 is located above the slide plate 202. The cylinder 203 is fixed to the baking machine 1 by a fixing plate. The cylinder 203 drives the suction cup 206 to descend, allowing the suction cup 206 to rise. The suction cup 206 can contact and adsorb the PCB board. After the PCB board is adsorbed, the cylinder 203 drives the suction cup 206 back to the initial position, and then the suction cup 206 releases the PCB board. The PCB board will fall onto the top of the slide plate 202 due to gravity. The top of the slide plate 202 is provided with several grooves 3 evenly distributed along its top length. The grooves 3 are provided with a hub frame 4. Several pulleys 5 are rotatably connected to the hub frame 4. The pulleys 5 are evenly distributed along the top width of the slide plate 202. The multiple pulleys 5 support the PCB board. During the process of the roller feeding module pulling the PCB board into the baking machine 1, the rolling friction between the PCB board and the slide plate can reduce the friction between the PCB board and the roller, thereby reducing the surface wear of the PCB board. The pulleys 5 are covered with rubber pads 7, which can play a buffering role, reduce the impact on the PCB board, and reduce the coefficient of friction, making it easier for the PCB board to drive the pulleys 5 to roll during the movement, thereby reducing the surface wear of the PCB board.

[0026] An elastic buffer mechanism 6 is provided within the groove 3. The elastic buffer mechanism 6 includes a frame 601, springs 602, and slide rods 603. Two slide rods 603 are provided, and their top ends are fixedly connected to the bottom of the wheel hub frame 4. The top of the frame 601 is provided with a sliding hole 604 that slides with the slide rods 603. Two springs 602 are provided and are fixedly connected to the bottom ends of the two slide rods 603 respectively. The other end of the springs 602 is fixed to the bottom of the frame 601. When the PCB board falls onto the pulley 5, the wheel hub frame 4 will be impacted. 4 will cause the slide bar 603 to press down, and the spring 602 will buffer the impact of the pulley 5 on the PCB board, thereby reducing the impact force of the pulley 5 on the PCB board and avoiding damage to the surface of the PCB board; the bottom of the slide bar 603 is provided with a limiting plate 605, which plays a limiting role; the bottom of the groove 3 is provided with a limiting groove 8 that matches the frame 601, which can disassemble and install the frame 601, and then the elastic buffer mechanism 6 can be disassembled to facilitate cleaning of the dust on the pulley 5 and avoid contaminating the PCB board.

[0027] The suction cup 206 is connected to the vacuum pump in the control system of the baking machine 1 through an air pipe. The roller feeding module 201, the cylinder 203 and the hydraulic cylinder 204 are all electrically connected to the control system of the baking machine 1.

[0028] Working principle:

[0029] like Figure 2 , 4As shown in Figure 5, when using the baking plate equipment of this utility model, the PCB board to be baked is stacked on the carrier plate 205, and then the baking plate machine 1 is started. Under the control of the control system of the baking plate machine 1, the cylinder 203 drives the suction cup 206 to descend, so that the suction cup 206 can contact the PCB board and adsorb the PCB board. After the PCB board is adsorbed, the cylinder 203 drives the suction cup 206 to rise back. During the process of the cylinder 203 driving the suction cup 206 to rise, the hydraulic cylinder 204 will drive the carrier plate 205 to rise by the thickness of the PCB board, which can avoid the situation where the suction cup 206 cannot contact the PCB board after descending. After the suction cup 206 returns to the initial position, it will release the PCB board, and the PCB board will fall onto the slide plate 202 due to gravity. When a PCB board falls onto the top pulley 5, the hub frame 4 will be impacted. The hub frame 4 will then drive the slide bar 603 to press down. The spring 602 will buffer the impact of the pulley 5 on the PCB board, thereby reducing the impact force of the pulley 5 on the PCB board and preventing damage to the surface of the PCB board. Afterwards, the PCB board on top of the pulley 5 will slide down to contact the roller feeding module 201. Finally, the roller feeding module 201 will start and pull the PCB board into the baking machine 1. The baking machine 1 will then perform the baking operation on the PCB board. During the process of the roller feeding module pulling the PCB board into the baking machine 1, the rolling friction between the PCB board and the pulley can reduce the friction between the PCB board and the slide plate, thereby reducing the surface wear of the PCB board.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
