Description

Technical Field

[0001] The present invention relates to the technical field of PCB patch technology, in particular to a PCBA patch processing device and a PCBA patch processing method. Background Art

[0002] PCBA refers to a printed circuit board mounted with various components. During the production process, it needs to be based on an unloaded PCB board, and then the corresponding electronic components are mounted on it, and finally it is prepared.

[0003] At present, the production process of PCBA includes multiple steps such as printing, patch, welding and testing, among which the patch step is to mount electronic components on the PCB board. The existing operation steps are to directly mount the components through the patch machine, and then connect the components and the PCB board firmly through reflow soldering, and then a PCBA is prepared. However, some components are easily damaged in high temperature environments, such as resistors, capacitors, and transistors. These components that are not resistant to high temperatures generally cannot be directly reflow soldered, so they need to be manually plugged in and then wave soldered. The specific operation steps are to transport the PCB board to be patched through the assembly line. When the PCB board is transported to the corresponding workstation, the worker needs to hold the electronic components, then align the pins of the electronic components with the sockets on the PCB board and insert them until several electronic components are firmly plugged in. The assembly line continues to transport the PCB board to the next workstation to prepare for wave soldering.

[0004] In the above production process, since the PCB boards on the assembly line are usually placed horizontally, workers must bend down to see the sockets on the PCB boards when performing plug-in operations. Over time, it is easy to cause neck pain in workers. Secondly, due to the large number of components that need to be installed, the manual patching method will lead to a high workload for operators and is not conducive to improving the production efficiency of the enterprise.

Specifically in this embodiment, the first rack 308 is located below the first gear 307, and when the first rack 308 remains stationary and the first gear 307 rolls above the first rack 308, the flip frame 302 will rotate upward.

[0055] The first rack 308 is provided with a light rod 309 that is distributed along the length direction of the mounting slot 201. The light rod 309 is fixedly connected to the inner wall of the mounting slot 201. A reset spring 310 is sleeved on the outside of the light rod 309.

In addition, the cross section of the clip 331 is L-shaped, and the clip 331 has a horizontal surface 33101 and a vertical surface 33102. Specifically, when clamping the PCB board to be mounted, the two ends of the PCB board can be placed on the horizontal surfaces 33101 of the two clips 331 respectively.

When the driving column 327 is in the When the drive column 327 is located inside the first straight segment 2041, the distance between the two clips 331 is greater than the width of the PCB board; when the drive column 327 is located inside the second straight segment 2041, the PCB board can be placed between the two clips 331, and the distance between the vertical surfaces 33102 of the two clips 331 is greater than the width of the PCB board; when the drive column 327 is located inside the third straight segment 2043, the distance between the vertical surfaces 33102 of the two clips 331 is equal to the width of the PCB board, that is, the two clips 331 can just clamp the PCB board. More specifically, when the bearing mechanism 300 is located at the first station, the drive column 327 is located inside the second straight segment 2041, and at this time, the flip frame 302 and the displacement frame 301 remain parallel.

[0063] It is worth mentioning that when the supporting mechanism 300 is located at the first working position, the driving column 327 is located inside the second straight segment 2041, and the first rack 308 is not engaged with the first gear 307; when the driving column 327 moves to the inside of the third straight segment 2043, the first gear 307 will engage with the first rack 308.

[0064] The upper surface of the base 100 is provided with an arc track 103 at the second station position, and the bottom end of the guide rod 320 is provided with a track column 334 adapted to the arc track 103. When the bearing mechanism 300 moves to the second station, the clamping frame 303 turns upward around the second main axis 317. That is, when the bearing mechanism 300 gradually moves to the second station, the track column 334 at the bottom end of the guide rod 320 will contact the arc track 103, and under the action of the arc track 103, the guide rod 320 is driven to descend, thereby rotating the clamping frame 303. Specifically, in this embodiment, when the bearing mechanism 300 is located at the second station, the clamping angle of the clamping frame 303 to the horizontal is 30°.

[0065] A patch storage plate 105 is provided on the upper surface of the fixed table 102 and opposite to the third station. The patch storage plate 105 is distributed vertically. A plurality of component storage slots 106 are provided on the side of the patch storage plate 105 facing away from the center of the turntable 200. The staff can put the components to be patched into the corresponding component storage slots 106, and place the pins of the components outward. A driven gear ring 205 is fixedly mounted on the inner ring wall of the turntable 200. A driving motor 104 is provided below the base 100. The output shaft of the driving motor 104 is coaxially connected to a driving gear 107, and the driving gear 107 is meshed with the driven gear ring 205. In this embodiment, the driving motor 104 can directly drive the turntable 200 to rotate in a counterclockwise direction.

[0066] Embodiment 2: This embodiment proposes a PCBA patch processing method, which is applicable to the PCBA patch processing device in Embodiment 1, and includes the following steps:

[0067] The turntable 200 intermittently rotates counterclockwise around the center of the turntable 200 on the base 100, and each rotation angle is 90°. At the same time, the external robot arm places the PCB boards to be mounted one by one on the supporting mechanism 300 located at the first station; since the four installation slots 201 are evenly distributed on the turntable 200, the center angle corresponding to two adjacent installation slots 201 is exactly 90°, that is, every time the turntable 200 rotates 90°, the supporting mechanism 300 originally located at the fourth station can move to the first station.

[0068] When the supporting mechanism 300 moves to the second station, the clamping frame 303 rotates upward so that the front side of the PCB board faces the side opposite to the center of the turntable 200. At this time, the worker at the second station installs some components on the PCB. In the process of the supporting mechanism 300 approaching the second station from the first station, first, the linear drive mechanism 305 controls the supporting mechanism 300 to move toward the side close to the center of the turntable 200 until the drive column 327 moves to the inside of the third straight segment 2043. At this time, the two clips 331 just clamp the PCB board. Then, under the action of the arc track 103, the clamping frame 303 is driven to rotate 30° so that the front side of the PCB board faces the side opposite to the center of the turntable 200. At this time, it is convenient for the staff to perform corresponding patch operations on the PCB board.

[0069] When the carrying mechanism 300 moves to the third station, the flip frame 302 rotates 90° toward the side of the circle center close to the turntable 200 to a vertical state, and the displacement frame 301 slides toward the side of the circle center close to the turntable 200, so that the patch on the patch storage plate 105 can be automatically inserted into the PCB board; in the process of the carrying mechanism 300 moving from the second station to the third station, the staff puts some components into the component storage slot 106 in advance, and places the pins of the components outward; after the carrying mechanism 300 moves to the third station, the linear drive mechanism 305 further drives the carrying mechanism 300 to move toward the side of the circle center close to the turntable 200, at this time, the first gear 307 first rolls on the first rack 308, so that the flip frame 302 rotates 90°, and then the flip frame 302 maintains a vertical posture and continues to approach the patch storage plate 105, until the pins of several components are all inserted into the corresponding jacks on the PCB board, and then the linear drive mechanism 305 controls the carrying mechanism 300 to return to the original path.

[0070] When the supporting mechanism 300 moves to the fourth workstation, the linear drive mechanism 305 drives the supporting mechanism 300 to move toward the side away from the center of the turntable 200 until the drive column 327 moves to the inside of the first straight segment 2041. At this time, the distance between the two clips 331 is greater than the width of the PCB board. Therefore, the PCB board can fall from the discharge port 101 to the output mechanism 400.

[0071] When the supporting mechanism 300 moves from the fourth station to the first station, the linear driving mechanism 305 controls the supporting mechanism 300 to move toward the side close to the center of the rotating disk 200 until the driving column 327 moves to the inside of the second straight segment 2041 .

[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
