Description

Technical field

[0001] The utility model relates to the technical field of printed circuit boards, and particularly relates to a bearing and desoldering device for a PCBA board. Background technique

[0002] PCBA is the abbreviation of Printed Circuit Board Assembly. That is to say, the whole process of the PCB bare board through SMT component mounting or DIP plug-in is abbreviated as PCBA.

When maintaining the PCBA board, it is necessary to disassemble it. When disassembling the traditional PCBA board, most of them are to manually hold the PCB board by hand to keep the PCB board fixed during disassembly. Such a fixing method not only increases the operation difficulty of employees, but also has a low manual pressing fixing strength, and it is easy to cause the PCB board to loosen due to excessive force during disassembly, affecting the disassembly efficiency of the PCB board.

Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a loading and desoldering device for a PCBA board, including a soldering station main body 1. An operation panel 11 is arranged on the front of the soldering station main body 1. A storage slot is arranged on the right side of the operation panel 11, and a soldering gun is arranged in the storage slot. A display screen 12 is fixed on the upper left side of the soldering station main body 1. The display screen 12 is electrically connected to an image collector 7. A welding arm mounting platform 13 is fixed at the back end of the display screen 12, which can be used to install a welding robot arm to further improve the welding efficiency. A desoldering slot 2 is arranged on the upper right side of the soldering station main body 1. A turning platform 3 is installed at the upper end of the desoldering slot 2. The turning platform 3 includes a rotating bracket. A rotating shaft 32 is rotatably arranged between the rotating brackets. A rotating motor 31 is fixed at the end of the rotating shaft 32. The rotating shaft 32 is fixedly connected to a vibrating table 4. A vibrating table 4 is fixed at the upper end of the turning platform 3. A desoldering loading platform 5 is arranged at the upper end of the vibrating table 4. A storage net 6 is arranged inside the desoldering slot 2, and the storage net 6 is located directly below the vibrating table 4. An image collector 7 is arranged at the inner wall of the desoldering slot 2. A movable hot air gun 8 is installed at the bottom of the desoldering slot 2;

[0022] Combined with the above structural features, when the utility model works, it can automatically heat the electronic components to be disassembled and then use high-frequency vibration to make them separate, without damaging other surrounding components, and the disassembly efficiency is high. Specifically: Fix the PCBA board to be disassembled on the upper end of the desoldering carrier 5. By starting the rotating motor 31, the rotating shaft 32 drives it to flip 180 degrees to make it upside down. After the image collector 7 collects the positions of the components on the PCBA board, they are displayed on the display screen 12. Through the operation panel 11, control the moving hot air gun 8 to move to the component to be disassembled and blow out hot air to dissolve the solder at the component connection. At this time, start the vibration table 4 to make the desoldering carrier 5 vibrate at high frequency, and cooperate with gravity to make the component separate and fall to the storage net 6. The disassembly effect is good. When the disassembly is completed, the turntable 3 flips again, and the operator can continue the soldering operation without removing the PCBA board, and the practicability is strong.

[0023] Please refer to Figures 1-5 , the vibration table 4 includes a platform support main body 41. At the four corners of the upper end of the platform support main body 41, there are vertical limit holes 42. The vertical limit holes 42 cooperate with the desoldering carrier 5 to limit the planar movement. There are limit card slots 43 arranged around the platform support main body 41. The limit card slots 43 are in contact connection with the desoldering carrier 5. A rectangular groove is arranged in the middle of the platform support main body 41. A vibration block 44 is slidably installed in the rectangular groove. The vibration block 44 is in a "concave" shape. A vibration spring 47 is arranged in the middle of it. The upper end of the vibration block 44 is in contact connection with the desoldering carrier 5. The lower end of the vibration block 44 is in contact connection with a cam 46. The end of the cam 46 is fixed with a vibration motor 45;

[0024] Combined with the above structural features, when the utility model works, the vibration motor 45 rotates, driving the cam 46 to rotate. When the cam 46 rotates one week, it drives the vibration block 44 to move upward once. When moving upward, the limit card slots 43 limit the vertical displacement of the desoldering carrier 5 to prevent it from detaching from the platform support main body 41. The return spring can accelerate the return of the vibration block 44, thereby realizing high-frequency vibration.

[0025] Please refer to Figures 1-5 , an adjustment groove 51 is arranged on the upper end of the desoldering carrier 5. A vertical pressing plate 52 is slidably installed in the adjustment groove 51. The end of the vertical pressing plate 52 is provided with an adjustment rod for adjusting its position. An adjustable clamping block 53 is slidably arranged on the vertical pressing plate 52 for fixing the PCBA board.

[0026] Combined with the above structural features, when the utility model works, the vertical pressing plate 52 can slide the adjustment rod in the adjustment groove 51, and can realize the clamping of the upper and lower sides of PCBA boards of different sizes. The adjustable clamping block 53 can also move and can realize the horizontal fixation of the PCBA board, with good flexibility and high fixing stability.

[0027] Working principle: When the utility model is in use, the PCBA board to be disassembled is fixed on the upper end of the desoldering carrier table 5. By starting the rotating motor 31, the rotating shaft 32 drives it to be flipped 180 degrees to be inverted. After the positions of the components on the PCBA board are collected by the image collector 7 and displayed on the display screen 12, the moving hot air gun 8 is controlled by the operation panel 11 to move to the component to be disassembled, and hot air is blown to dissolve the solder at the component connection. At this time, the vibration table 4 is started to make the desoldering carrier table 5 vibrate at a high frequency, and cooperate with gravity to make the component break away and fall to the storage net 6. The disassembly effect is good. When the disassembly is completed, the flipping table 3 is flipped again, and the operator can continue the soldering operation without removing the PCBA board, which has strong practicability;

[0028] Among them, when the vibration table 4 works, the vibration motor 45 rotates, driving the cam 46 to rotate. When the cam 46 rotates one week, it drives the vibration block 44 to move upward once. When moving upward, the limit card slot 43 restricts the vertical displacement of the desoldering carrier table 5 to prevent it from detaching from the platform support body 41. The return spring can accelerate the reset of the vibration block 44, thereby realizing high-frequency vibration.
