Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of circuit board processing, specifically relates to a feeding and discharging device for circuit board processing. BACKGROUND

[0002] The laser light drawing machine is also called a laser engraving machine, and is referred to as a light drawing machine. The laser light drawing machine is a set of laser optical technology, microelectronic technology and ultra-precision machinery, and is a photographic product. The laser light drawing machine is used for drawing various patterns, images, texts or symbols on photosensitive film. The laser light drawing machine is widely used in the field of pcb (printed circuit board) printing. In the automatic light drawing and engraving process, an upper and lower feeding and discharging device needs to be arranged to convey the processing materials.

[0003] In the related prior art, for example, a full-automatic laser engraving machine is disclosed in Chinese Patent No. CN220050471U. The full-automatic laser engraving machine comprises an engraving machine base, a support platform fixedly connected to the top end of the engraving machine base, and a movable seat provided at the top end of the support platform. The movable seat, the motor and the transmission wheel are arranged. During use of the engraving machine, the movable seat is first connected to the existing material conveying device at both ends through the hydraulic rod, and then the motor is started to drive the transmission wheel to rotate through the meshing connection of the worm gear and the worm, so as to realize the transportation of the material on the top end of the engraving machine base. When the material is conveyed to the appropriate position, the hydraulic rod drives the movable seat to reset so that the material falls on the top end of the processing platform, so that the engraving machine can be engraved and processed, and the automatic feeding and discharging of the material is realized. Manual handling of the material from the conveying device for processing is avoided, thereby improving the engraving efficiency of the engraving machine.

[0004] However, in actual use, the distance between the two transmission wheels cannot be adjusted, which leads to the fact that the width of the conveyed material, i.e. the width of the circuit board, needs to be greater than the minimum distance between the two transmission wheels. Otherwise, when the material is conveyed to the movable seat, the material will fall between the two transmission wheels, which leads to the fact that the transmission wheels cannot abut against the conveyed material. That is, the above-mentioned device limits the processing size of the material, which leads to the fact that the application range is small, and this is not conducive to actual use. UTILITY MODEL CONTENTS

[0005] The utility model intends to provide a feeding and discharging device for circuit board processing, so as to solve the problem of small application range of the prior art mentioned above.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a feeding and discharging device for circuit board processing, comprising

[0007] The body has a processing table on the body, and a lifting plate group is installed at the center of the processing table;

[0008] The feeding mechanism includes two feeding units symmetrical about the lifting plate assembly. Each feeding unit includes a fixed frame, a horizontal moving component, a vertical moving component, and a conveying component. The fixed frame is fixed to the side wall of the processing table. The horizontal moving component is connected to the vertical moving component and is installed inside the fixed frame. The conveying component includes a side plate, a conveyor motor, and a conveyor belt. The side plate is connected to the horizontal moving component. The conveyor motor is installed on the side of the side plate near the fixed frame, and the conveyor belt is installed on the side of the side plate away from the fixed frame. The conveyor belt is connected to the rotating end of the conveyor motor.

[0009] The principle and effects of this technical solution:

[0010] 1. The device is capable of photolithography on circuit boards by setting up the main body of the photoplotter and the processing table. Furthermore, the lifting plate group allows the circuit boards placed on the processing table to be raised to a certain height, which facilitates the feeding mechanism to transport the circuit boards.

[0011] 2. By setting up horizontal and vertical moving components, the conveying component can move closer to and further away from the circuit board on the lifting plate group. Simultaneously, the height of the conveying component relative to the lifting plate group can be controlled by raising and lowering it. Specifically, by lowering the upper surface of the conveying component below the upper surface of the lifting plate group, the circuit board on the conveying component can be placed against the lifting plate group. Then, by moving the conveying component away from the circuit board, the lifting plate group can be lowered to place the circuit board on the processing table for processing. After processing, by raising the lifting plate group to make the circuit board higher than the processing table, the conveying component moves closer to the circuit board. After the horizontal moving component moves into position, the height of the conveying component is controlled by the vertical moving component, allowing the conveying component to touch the bottom of the circuit board and continue to raise the circuit board, thus detaching the circuit board from the lifting plate group. This allows the processed circuit board on the conveying component to be unloaded, thus completing the automatic loading and unloading function.

[0012] 3. By controlling the rotation of the conveyor belt through the conveyor motor, the circuit board can move along the length of the side plate after it is placed on the conveyor belt, thereby completing the steps of loading, processing and unloading. The side plate can also limit the edge of the circuit board, making the position of the circuit board more stable during transportation.

[0013] 4. By setting up horizontal and vertical moving components, the conveying component can be positioned according to the width of the circuit board, thus making the device more widely applicable.

[0014] The present invention is further configured such that: the vertical moving component includes a vertical motor, a drive screw and a drive plate, the vertical motor is mounted on the top of the fixed frame, the drive screw is rotatably mounted in the fixed frame and the top of the drive screw extends to be connected to the rotating end of the vertical motor, the drive plate is slidably fitted in the fixed frame and threadedly fitted on the drive screw, and the horizontal moving component is mounted on the drive plate.

[0015] The principle and effect of this technical solution are as follows: A vertical motor drives a drive screw to rotate, which in turn allows the drive plate to slide up and down within a fixed frame. This causes the horizontal moving component connected to the drive plate to move up and down. Since the conveying component is installed on the horizontal component, the conveyor belt of the conveying component can move the circuit board up and down. That is, during loading and unloading, the height of the circuit board can be controlled by the vertical moving component to be higher than the height of the lifting plate group, so that the circuit board can be conveyed normally. After being conveyed to the correct position, the height of the conveyor belt is lowered so that the circuit board is placed against the lifting plate group. Then, the horizontal moving component moves the conveyor belt away from the circuit board, which controls the lifting plate group to descend, so that the circuit board is placed against the processing table for processing. During unloading, after processing is completed, the lifting plate group is raised, and the conveyor belts on both sides are brought closer to the circuit board. Then, the drive plate raises the height of the conveyor belt so that the conveyor belt touches and lifts the circuit board away from the lifting plate group, thus automatically unloading the circuit board.

[0016] The present invention is further configured such that: the lateral movement component includes an electric telescopic rod, the electric telescopic rod is fixed to the drive plate, and the movable end of the electric telescopic rod passes through the drive plate and is fixed to the side plate.

[0017] The principle and effect of this technical solution: By setting up an electric telescopic rod, the side plate can be moved horizontally, thereby allowing the conveyor belts on both sides to move closer to or further away from the circuit board, thus adapting to circuit boards of different widths and increasing the applicability.

[0018] The present invention is further configured such that: the feeding unit also includes an upper pressing component, the upper pressing component includes a horizontal slide rod, a vertical slide rod and an upper pressing plate, the horizontal slide rod is arranged laterally on the side wall of the upper pressing plate, the vertical slide rod is arranged vertically on the side wall of the upper pressing plate, a horizontal slide sleeve is fixed at the top of the fixed frame, the horizontal slide rod is slidably inserted into the horizontal slide sleeve, a vertical slide sleeve is fixed on the side of the side plate near the fixed frame, and the vertical slide rod is slidably inserted into the vertical slide sleeve.

[0019] The principle and effect of this technical solution: By setting up the horizontal sliding rod, horizontal sliding sleeve, and upper pressure plate, the position of the upper pressure plate can only move horizontally relative to the fixed frame. By setting up the vertical sliding rod and vertical sliding sleeve, the position of the upper pressure plate can move synchronously with the side plate. That is, the upper pressure plate and the conveyor belt move closer to or further away from the circuit board at the same time, so as not to interfere with the normal processing of the circuit board. At the same time, it does not interfere with the vertical movement of the side plate relative to the upper pressure plate. Therefore, when the feeding mechanism is loading and unloading, the conveyor belt can lift the circuit board away from the lifting plate group by moving up relative to the processing table. After continuing to move upward, the top of the circuit board can contact the upper pressure plate, thus the circuit board is vertically limited during loading and unloading, and can only move horizontally, thereby ensuring the stability of the circuit board during transportation.

[0020] The present invention is further configured such that: the upper pressing assembly also includes a plurality of elastic rolling elements arranged at intervals along the length direction of the upper pressing plate. The elastic rolling elements include a telescopic sleeve, a spring and a roller. The telescopic sleeve is fixed to the bottom of the upper pressing plate, the roller is fixed to the bottom of the telescopic sleeve, and the spring is sleeved on the telescopic sleeve and located between the upper pressing plate and the roller.

[0021] The principle and effect of this technical solution: Since the elastic rolling component consists of a telescopic sleeve, a spring, and a roller, when the roller comes into contact with the circuit board below, it can compress the telescopic sleeve and the spring, thereby causing the roller to move upward to make way for the circuit board. This avoids the circuit board from being worn or damaged due to excessive raising of the vertical moving component. Furthermore, by having the roller come into contact with the upper surface of the circuit board, sliding friction is changed to rolling friction. This can vertically limit the movement of the circuit board while preventing the circuit board from being worn, thus improving the product yield.

[0022] The present invention is further configured such that: the lifting plate assembly includes a control plate and lifting rods, a clearance groove is provided on the processing table, and multiple lifting rods are arranged at intervals in the clearance groove. The top of the lifting rods is connected to the bottom of the control plate, and the control plate is adapted to the clearance groove.

[0023] The principle and effect of this technical solution: The control board is raised or lowered by the lifting rod, so that the control board can be raised or lowered relative to the processing table. This allows the material on the feeding mechanism to be placed on the processing table through the control board, or it can return to the feeding mechanism through the control board for feeding, thereby realizing the function of automatic loading and unloading.

[0024] The present invention is further configured such that: the lifting plate assembly also includes an air suction pipe, an air pump and multiple suction nozzles, the multiple suction nozzles are arranged at intervals on the top of the control plate, the bottom of the suction nozzles are connected to the air suction pipe, the air suction pipe passes through the processing table and is connected to the air pump, and the air pump is located at the bottom of the processing table.

[0025] The principle and effect of this technical solution: The suction pump provides suction to the suction pipe, which in turn enables the suction nozzle on the control board to provide adsorption force to the material above, i.e., the circuit board. This allows the circuit board to be adsorbed by the control board and kept in a fixed position when placed on it, thereby improving the accuracy of photoplotting. At the same time, it prevents the circuit board from tipping over during the lifting and lowering of the control board, ensuring the reliability of the device during use. Attached Figure Description

[0039] As attached Figures 1-10 As shown, this utility model discloses a circuit board processing loading and unloading device, including a body 101, a lifting plate group and a feeding mechanism.

[0042] The feeding mechanism includes two feeding units symmetrical about the lifting plate group. Each feeding unit includes a fixed frame 301, a horizontal moving component, a vertical moving component, a conveying component, and an upper pressing component. The fixed frame 301 is fixed to the side wall of the processing table 102. The conveying component includes a side plate 302, a conveying motor 303, and a conveyor belt 304. The side plate 302 is connected to the horizontal moving component. The conveying motor 303 is installed on the side of the side plate 302 close to the fixed frame 301, and the conveyor belt 304 is installed on the side of the side plate 302 away from the fixed frame 301.

[0043] The vertical moving component includes a vertical motor 401, a drive screw 402, and a drive plate 403. The vertical motor 401 is mounted on the top of the fixed frame 301. The drive screw 402 is rotatably mounted inside the fixed frame 301, and the top of the drive screw 402 extends to connect with the rotating end of the vertical motor 401. The drive plate 403 is slidably fitted inside the fixed frame 301, and the drive plate 403 is threaded onto the drive screw 402. The horizontal moving component is mounted on the drive plate 403.

[0044] The lateral movement assembly includes an electric telescopic rod 404, which is fixed to the drive plate 403, and the movable end of the electric telescopic rod 404 passes through the drive plate 403 and is fixed to the side plate 302.

[0045] The upper pressing assembly includes a horizontal slide bar 502, a vertical slide bar 504, an upper pressing plate 501, and multiple elastic rolling elements spaced apart along the length of the upper pressing plate 501. The horizontal slide bar 502 is arranged laterally on the side wall of the upper pressing plate 501, and the vertical slide bar 504 is arranged vertically on the side wall of the upper pressing plate 501. A horizontal slide sleeve 503 is fixed to the top of the fixed frame 301, and the horizontal slide bar 502 is slidably inserted into the horizontal slide sleeve 503. A vertical slide sleeve 505 is fixed to the side of the side plate 302 near the fixed frame 301, and the vertical slide bar 504 is slidably inserted into the vertical slide sleeve 505.

[0046] The specific implementation process is as follows:

[0047] The conveyor motor 303, vertical motor 401, electric telescopic rod 404, lifting rod 202, and air pump all operate intermittently. One end of the processing table 102 is connected to the circuit board loading mechanism, and the other end is connected to the circuit board unloading mechanism. The conveying surfaces of both the loading and unloading mechanisms are higher than the upper surface of the control board 201 when it is at its highest position. After the movement parameters of each instrument and device are adjusted, the complete working sequence is as follows: the loading mechanism delivers the circuit board, at which point the height of the conveyor belt 304 is flush with the conveying end of the loading mechanism. The circuit board is delivered onto the conveyor belt 304. Then, the drive motor drives the conveyor belt 304 to rise until the circuit board abuts against the bottom of the roller 508. Then, the conveyor motor 303 is started, intermittently conveying one end of the distance. Then, the conveyor motor 303 stops, and the vertical motor 401 drives the drive plate 403, i.e., the conveyor belt 304, to move down until the circuit board leaves the conveyor belt 304 and is placed on the control board 201. At this time, the air pump starts to extract air, causing the suction nozzle 20... Three negative pressure adsorption circuit boards are formed at three points. Then, the electric telescopic rod 404 controls the conveyor belt 304 to move away from the circuit board. After the conveyor belt 304 is completely away from the circuit board, the lifting rod 202 descends, so that the control board 201 is stored in the clearance groove 103. At this time, the circuit board is placed against the surface of the processing table 102. The engraving end on the laser engraving machine body 101 is used to process the circuit board. After the processing is completed, the lifting rod 202 rises so that the control board 201 reaches the highest point. At this time, the circuit board is at the highest point. Then, through the control of the electric telescopic rod 404 and the vertical motor 401, the conveyor belt 304 is brought into contact with the circuit board. At this time, the air pump stops working. Then, the vertical motor 401 continues to control the circuit board to rise until it is in contact with the roller 508. Then, the conveyor motor 303 starts, and the conveyor belt 304 controls the circuit board to be conveyed to the unloading mechanism side, thereby completing the unloading of the circuit board. At the same time, the loading mechanism loads the conveyor belt 304, thus completing the automated loading and unloading process.
