Description

Technical Field

[0001] This utility model relates to the field of PCB board production, and in particular to a spray painting device for PCB board production. Background Technology

[0002] Spray painting of PCB boards helps to improve their lifespan and reliability. Spray-painted PCB boards have effects such as moisture resistance, mildew resistance, and corrosion resistance. The existing spray painting method generally involves placing or transporting a single PCB board to a designated location and using spray painting equipment to perform the spray painting operation. After the spray painting is completed, the next PCB board is placed or transported, which is inefficient. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a PCB board production spraying device that can complete the conveying process simultaneously with the spraying, thereby improving efficiency.

[0004] The technical solution of this utility model is as follows:

[0005] A PCB board production painting device includes a worktable, a rotating support mechanism, a pusher, a painting mechanism, and an ejector. The rotating support mechanism includes a support plate, a rotating shaft, and a drive device. The drive device is located inside the worktable. The bottom end of the rotating shaft passes through the worktable and connects to the drive device. The support plate is located at the top of the rotating shaft. The top of the support plate has four grooves arranged in a ring. Each groove passes through one edge of the support plate, and a support block slides within the groove. The worktable has an input device and an output device for the PCB board on adjacent perpendicular sides. The pusher is located on the side of the support plate away from the output device. The painting mechanism includes an XYZ three-axis mechanism and a painting head mounted on it. The XYZ three-axis mechanism is located on the side of the support plate away from the input device, and the ejector is located on the side of the support plate closer to the output device.

[0006] In a further technical solution, the width of the chute matches the PCB board to be processed, and the thickness of the support block is less than the depth of the chute.

[0007] In a further technical solution, the pusher includes a first cylinder and a first push plate located at the end of the first cylinder.

[0008] In a further technical solution, the length of the chute is less than the PCB board to be processed; the bottom side of the first push plate is provided with a push block whose top surface is flush with the top surface of the support block, and the vertical distance from the side of the push block away from the first push plate to the push plate is equal to the length difference between the chute and the PCB board.

[0009] In a further technical solution, a movable groove is provided in the middle of one side of the sliding groove, and a top block is provided at the bottom of the support block that passes through the movable groove; the pusher is located at the bottom of the support plate and includes a second cylinder and a second push plate located at the end of the second cylinder, and the movement trajectory of the second push plate intersects with the top block.

[0010] In a further technical solution, both the input device and the output device are docking stations.

[0011] The beneficial effects of this utility model are:

[0012] 1. The input device can transport the PCB board to the support block of the support plate. The drive device can rotate the support plate to the pusher, pushing the support block and the PCB board completely into the slide. After being pushed in, the PCB board can rotate with the support plate to one side of the painting mechanism. The XYZ three-axis mechanism can drive the painting head to move and paint the PCB board. Finally, it rotates to one side of the output device and is pushed to the output device by the pusher. In the above process, each rotation of the support plate can transport one PCB board from the input device to the support block, and repeat the above steps. The next PCB board can be prepared while painting, and the input and output operations can be completed, improving efficiency.

[0013] 2. The sidewall of the chute is higher than the support block, so that the sidewall of the chute can limit the PCB board to be painted, which is conducive to the accurate painting of the painting equipment.

[0014] 3. The length of the slide is less than that of the PCB board, so that part of the PCB board always extends outside the slide, which is beneficial for connecting input and output devices. Attached Figure Description

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figures 1-4 As shown, a PCB board production spraying device includes a worktable 10, a rotating support mechanism, a pusher, a spraying mechanism, and a pusher. The rotating support mechanism includes a support plate 20, a rotating shaft 21, and a drive device. The drive device is a stepper motor, located inside the worktable 10 (not shown in the figure). The bottom end of the rotating shaft 21 passes through the worktable 10 and is connected to the stepper motor shaft. The support plate 20 is located at the top of the rotating shaft 21. The top of the support plate 20 has four grooves 22 arranged in a ring. The grooves 22 pass through one side of the edge of the support plate 20, and a support block 23 is slidably arranged inside the grooves 22. Input devices 30 and output devices 40 for PCB boards are respectively provided on adjacent perpendicular sides of the worktable 10. A connecting platform is selected, and the push-in component is located on the side of the support plate 20 away from the output device 40, including a first cylinder 51 and a first push plate 52 located at the end of the first cylinder 51; the painting structure is the existing XYZ three-axis mechanism 61 and the painting head 62 located on it. The XYZ three-axis mechanism 61 is located on the side of the support plate 20 away from the input device 30, and the push-out component is located on the side of the support plate 20 close to the output device 40. A movable groove 24 is provided in the middle of the side through which the slide 22 passes, and a top block 25 is provided at the bottom of the support block 23 that passes through the movable groove 24; the push-out component is located at the bottom of the support plate 20, including a second cylinder 71 and a second push plate 72 located at the end of the second cylinder 71, and the movement trajectory of the second push plate 72 intersects with that of the top block 25.

[0024] The working principle of the above technical solution is as follows:

[0025] In use, the PCB board is input from the input device 30 onto the support block 23 of the support plate 20 facing the input device 30. The drive device rotates 90 degrees each time, which can turn the PCB board to the side where the pusher is located. The first cylinder 51 drives the first push plate 52 to push the support block 23 and the PCB board completely into the slide groove 22. After being pushed in, the PCB board can rotate with the support plate 20 to the side of the painting mechanism. The XYZ three-axis mechanism 61 can drive the painting head 62 to move and paint the PCB board. Finally, it turns to the side of the output device 40. The second cylinder 71 can drive the second push plate 72 to push the top block 25, so that the support block 23 is partially moved out of the slide groove 22 and close to the output device 40. The PCB board on the support block 23 contacts the output device 40 to complete the output. The above steps can be repeated every time the support plate 20 rotates. The next PCB board can be prepared while painting, and the input and output operations can be completed.

[0026] In another embodiment, the width of the chute 22 matches the PCB board to be processed, and the thickness of the support block 23 is less than the depth of the chute 22.

[0027] The sidewall of the slide 22 is higher than the support block 23, so that the sidewall of the slide 22 can limit the PCB board to be painted, which is conducive to the accurate painting of the painting equipment.

[0028] In another embodiment, such as Figure 2 As shown, the length of the chute 22 is less than the PCB board to be processed; the bottom side of the first push plate 52 is provided with a push block 53 whose top surface is flush with the top surface of the support block 23, and the vertical distance from the side of the push block 53 away from the first push plate 52 to the push plate is equal to the length difference between the chute 22 and the PCB board.

[0029] The length of the slide 22 is less than that of the PCB board, so that the PCB board always extends part of the slide 22, which is beneficial for connecting the input device 30 and the output device 40; the pusher can contact the PCB board at the same time as the push block 53 contacts the support block 23 to push it.

[0030] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
