Description

Technical Field

[0001] The utility model relates to the technical field of electronic component production, in particular to a drying device for electronic component production. Background Art

[0002] Electronic components are components of electronic elements and small machines and instruments. They are often composed of several parts and can be used interchangeably in similar products. They usually refer to certain parts in industries such as electrical appliances, radio, and instruments. They are the general term for electronic devices such as printed circuit boards (i.e., PCB boards), capacitors, transistors, hairsprings, and mainsprings. Among them, PCB boards are almost used in every electronic device, from small electronic watches and calculators to computers, communication electronic devices, and military weapon systems. As long as there are electronic components such as integrated circuits, PCB boards are used for their electrical interconnection. During the production process of PCB boards, a drying device is needed to dry the PCB boards. Therefore, the Chinese authorized utility model patent (Publication No.: CN218328967U) proposes a drying device for PCB boards. The device inserts the PCB boards into the drying box body along the insertion slots, and by energizing the heating tubes, the temperature inside the box is increased to dry the PCB boards. It speeds up the drying speed of the paint on the PCB boards and improves the production efficiency.

[0003] However, when taking out the electronic components placed in the drying box after drying, the PCB boards can only be taken out one by one from the bearing slots by workers. The material taking speed is slow, which takes a long time and relatively affects the drying efficiency of the device. Moreover, the taken-out PCB boards need to be re-stacked by workers, the operation is relatively cumbersome, which consumes the physical strength of workers and increases the labor intensity of workers.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Refer to Figures 1-4 , a drying device for the production of electronic components, including a base 1, a clamping assembly 4 and an aggregate hopper 8. A drying box body 2 is arranged on the base 1. A plurality of insertion slots 203 are opened on the top surface of the drying box body 2, which can facilitate the placement of the PCB board 3 into the drying box body 2. A lifting device is arranged in the drying box body 2. A bearing plate is arranged on the lifting device. A plurality of bearing grooves are arranged on the bearing plate, which can facilitate the placement of the PCB board 3. The plurality of insertion slots 203 correspond to the plurality of bearing grooves one by one. The PCB board 3 is vertically fitted in each of the plurality of bearing grooves, and the top of the PCB board 3 passes through the insertion slot 203.

[0026] A pair of rectangular grooves 201 are formed on the top surface of the drying box body 2. A motor 7 is arranged in the rectangular groove 201. The output end of the motor 7 is connected with a bidirectional screw rod 5. Mounting holes are formed in the rectangular groove 201. Bearings are fitted in the mounting holes. The inner ring of the bearing is fitted with the surface of one end of the bidirectional screw rod 5 far away from the motor 7. A pair of sliding blocks 501 are in threaded fit with the bidirectional screw rod 5. The sliding blocks 501 are fitted with the rectangular groove 201. Hydraulic push rods 6 are mounted on both of the pair of sliding blocks 501.

[0027] There are a pair of clamping assemblies 4. The bottoms on both sides of the clamping assemblies 4 are connected with the output ends of one pair of the hydraulic push rods 6.

[0028] The clamping assembly 4 includes a clamping plate 401. The side of the PCB board 3 is fitted with the arc-shaped positioning groove 4011. Anti-slip rubber pads are arranged in the clamping plate 401. A number of arc-shaped positioning grooves 4011 are formed in the clamping plate 401. Fixed blocks 402 are mounted at both ends of the clamping plate 401. Through grooves 4021 are formed in the fixed blocks 402. A pair of round holes 4022 are formed in the fixed blocks 402. The through groove 4021 is located between the pair of round holes 4022. Stabilizing rods 405 are fitted in both of the pair of round holes 4022. The fixed blocks 402 can be stably moved through the stabilizing rods 405. One ends of the pair of stabilizing rods 405 are connected with a T-shaped connecting plate 406. One end of the T-shaped connecting plate 406 is provided with a mounting plate. The bottom of the mounting plate is connected with the output end of the hydraulic push rod 6. A movable rod 403 is fitted in the through groove 4021. A spring 404 is in clearance fit with the surface of one end of the movable rod 403. A T-shaped connecting plate 406 is arranged at one end of the movable rod 403 far away from the spring 404. A reinforcing inclined plate is arranged at the bottom of the T-shaped connecting plate 406. The reinforcing inclined plate is connected with the mounting plate and can support the T-shaped connecting plate 406 to improve the strength of the T-shaped connecting plate 406.

[0029] After several PCB boards 3 are dried by the heating tubes arranged in the base 1, the PCB boards 3 on the carrier plate are vertically lifted out of the base 1 through the lifting device in the base 1, so that several PCB boards 3 are above the top of the base 1. Then, a pair of motors 7 are started, and the output ends of the motors 7 drive the bidirectional screw 5 to rotate in the rectangular groove 201. Through the rotation of the bidirectional screw 5, a pair of sliding blocks 501 on the bidirectional screw 5 slide towards each other, thereby driving a pair of hydraulic push rods 6 on the pair of sliding blocks 501 to move towards each other. Since the output ends of one pair of hydraulic push rods 6 parallel to and in the same horizontal plane as the clamping plate 401 are connected to a pair of T-shaped connecting plates 406 on the clamping assembly 4, through the rotation of the pair of bidirectional screws 5, the pair of clamping assemblies 4 move towards each other, so that one side of the pair of clamping plates 401 simultaneously moves towards the vicinity of several PCB boards 3. When several arc-shaped positioning grooves 4011 formed on the clamping plate 401 cooperate with the two side edges of several PCB boards 3 and exert extrusion on the two side edges of the PCB boards 3, at this time, the clamping plate 401 receives the reaction force of the PCB boards 3, causing the movable rod 403 to slide in the through groove 4021 of the fixed block 402, and a pair of stabilizing rods 405 respectively slide in a pair of circular holes 4022. Through the sliding of the movable rod 403, the spring 404 sleeved on the surface of the movable rod 403 contacts and is extruded against one side of the fixed block 402. After the spring 404 is extruded, it contracts. Through the resilience of the spring 404, the arc-shaped positioning grooves 4011 on the clamping plate 401 and the side edges of the PCB boards 3 are stably fitted, and due to the elastic characteristics of the spring 404, it is avoided that the excessive extrusion force of the clamping plate 401 on the PCB boards 3 causes damage to the side edges of the PCB boards 3. After several PCB boards 3 are fixedly clamped, two pairs of hydraulic push rods 6 are started synchronously. The output ends of the hydraulic push rods 6 push a pair of clamping assemblies 4 to move upward, so that several PCB boards 3 are separated from the carrier grooves on the carrier plate and leave the slots 203 on the base 1, making several PCB boards 3 move to the vicinity above the top of the base 1, thereby enabling all the PCB boards 3 placed in several carrier grooves to be automatically taken out, avoiding workers taking out the PCB boards 3 one by one from the carrier grooves in the base 1, greatly improving the taking-out speed of the PCB boards 3, effectively shortening the material-taking operation time, and improving the drying efficiency of the device.

[0030] A pair of slide bars 801 are arranged at the bottom of the aggregate hopper 8, and a pair of sliding grooves 202 are formed on the top surface of the drying box body 2. The slide bars 801 are matched with the sliding grooves 202.

[0031] After a number of PCB boards 3 are fixedly clamped by a pair of clamping assemblies 4 and then lifted above the top of the base 1, at this time, the aggregate hopper 8 is pushed. Through the cooperation of the slide bar 801 and the chute 202, the aggregate hopper 8 moves on the top surface of the base 1. After the aggregate hopper 8 is pushed near the bottom of the PCB board 3, then the output ends of the two pairs of hydraulic push rods 6 move downward synchronously, so that the bottom ends of the number of PCB boards 3 enter the aggregate hopper 8 and contact the bottom of the aggregate hopper 8. Then, a pair of motors 7 drive a pair of bidirectional screws 5 to rotate, so that a pair of clamping assemblies 4 move toward the two sides away from the PCB board 3. At this time, the movable rod 403 slides in the through groove 4021, and the spring 404 separates from the side surface of the fixed block 402. The spring 404 rebounds, and a pair of stabilizing rods 405 slide in a pair of circular holes 4022 respectively, thereby releasing the fixed clamping of the number of PCB boards 3, so that the number of PCB boards 3 are stacked in the aggregate hopper 8. Then, the output ends of the two pairs of hydraulic push rods 6 move upward synchronously, and a pair of clamping assemblies 4 are moved above the top of the number of PCB boards 3. Then, the aggregate hopper 8 is pulled, the slide bar 801 is removed from the chute 202, and then the aggregate hopper 8 is placed in a suitable position, so that all the taken-out PCB boards 3 can be directly collected and stacked, the operation is convenient, the physical consumption of workers is effectively reduced, and the labor intensity of workers is reduced.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
