Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, and specifically relates to a feeding and drying device for circuit boards after cleaning. Background Technique

[0002] Circuit board drying is a step in circuit board processing. During the manufacturing process of circuit boards, a certain amount of moisture may be adsorbed. If the circuit boards are not dried before the electronic components are pasted, the moisture may turn into water vapor during the soldering process, resulting in problems such as poor solder joint quality, poor soldering, or even short circuits. Therefore, a drying device is needed to remove the moisture on the circuit boards and improve the soldering quality and reliability.

[0003] In the prior art, the patent application number "CN201922031854.7" is disclosed, which is a cleaning and drying device for circuit board processing, including a conveying device, a water tank, and a drying box.

A servo motor 12 is fixedly connected to the right side of the driving gear rotating shaft 11 through a motor mounting plate. Four U-shaped connecting plates 18 are installed inside the drying device main body 100. Heating rods 19 are connected to the inner sides of the four U-shaped connecting plates 18. The heating rods 19 can also be energized to heat the air for drying the circuit board.

[0029] On one side inside the main body 100 of the drying device, a temperature sensor 14 is fixedly installed. The model of the temperature sensor 14 is TR / 02016. A controller 15 is installed on the right side of the main body 100 of the drying device. The model of the controller 15 is DATA-7133.

A sealing door 20 is fixedly provided on the front side of the main body 100 of the drying device.

[0030] At the bottom end inside the storage rack 6, partition plates 23 are connected in an array. At the top end inside the storage rack 6, first springs 21 are connected in an array. The lower side of the first spring 21 is fixedly connected to a top plate 22. Through the setting of the top plate 22, the top plate 22 can be used to elastically clamp above the circuit board to keep the circuit board in a stable installation state, facilitating the drying work. A circuit board main body 28 is placed inside the storage rack 6. Second springs 26 are connected in an array on the inner side surface of the storage rack 6. A pressing plate 27 is installed on the front side of the second spring 26. At the bottom end inside the storage rack 6, first rubber pads 24 distributed in an array are connected. Second rubber pads 25 are connected at both ends inside the storage rack 6.

[0031] On the front side of the storage rack 6, two symmetrically arranged fixing seats 29 are fixedly installed. An embedded cross plate 30 is clamped on the upper sides of the two fixing seats 29. On one side of each of the two fixing seats 29, a second bolt 33 for fixing the embedded cross plate 30 is threadedly connected. A telescopic plate 31 for fixing the circuit board main body 28 is slidably connected to the rear side of the embedded cross plate 30.

The right side of the first rotating shaft seat 2 penetrates through the first side plate 1 and extends to the right side of the first side plate 1. The gear seat 10 and the driving gear rotating shaft 11 are meshed with each other.

[0033] The working principle of a circuit board cleaning and feeding drying device provided by the present utility model is as follows:

[0034] By placing the circuit board inside the storage rack 6, the partition board 23 in the storage rack 6 can play a partitioning role at this time, preventing the circuit boards from all stacking together. Subsequently, the moving rollers 7 at the two L-shaped blocks 5 are respectively placed into the first rotating shaft seat 2 and the second rotating shaft seat 4. In this way, the moving rollers 7 can drive the storage rack 6 into the interior of the drying device main body 100. Then, the two vertical insertion plates 8 are inserted into the two rotating shaft seats, and then the two horizontal insertion posts 17 are snapped onto the two vertical insertion plates 8 to limit and fix the two storage racks 6 at the storage rack 6, enabling the storage rack 6 to be fixed stably and reliably. Subsequently, the sealing door 20 is closed, and then the hot air blower 13 is started. The hot air blower 13 will heat the air. Then, the output shaft of the servo motor 12 drives the driving gear rotating shaft 11 to rotate, so that the driving gear rotating shaft 11 can drive the engaged gear seat 10 to rotate, and the storage racks 6 at the two rotating shaft seats can be turned over. In this way, the hot air can pass through the through holes 9 and evenly dry the circuit boards inside the storage rack 6, improving the processing efficiency of the drying device. At the same time, as long as the limit on the two L-shaped blocks 5 is released, the storage rack 6 can be easily moved out of the drying device by the moving rollers 7, so as to take out the circuit boards after feeding and drying at one time, saving time and effort;

[0035] Through the installation of the circuit board, the top plate 22 equipped with the first spring 21 can adaptively press and fix the circuit board. Subsequently, the embedded cross plate 30 is snapped into the two fixing seats 29, and then the two second bolts 33 are used to press and fix the embedded cross plate 30 to ensure the stability of the embedded cross plate 30 during installation. Then, the telescopic plate 31 equipped with the third spring 32 and the pressing plate 27 equipped with the second spring 26 at the embedded cross plate 30 can press against the front and back sides of the circuit board. In this way, circuit boards of different sizes can be elastically clamped and dried flexibly, enabling the circuit boards to be dried stably and reliably. At the same time, the first rubber pad 24 and the second rubber pad 25 can play a positioning role to protect the circuit boards inside the storage rack 6 and avoid damaging the circuit boards.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
