Description

Technical Field

[0001] This utility model belongs to the field of FPC board production technology, specifically relating to a fixed-point FPC board UV adhesive curing device. Background Technology

[0002] In the production process of flexible printed circuit boards (FPCs), UV lamps are used to irradiate the connectors after they have been coated with adhesive, so that the UV adhesive reaches the set radiation level to protect the connector solder pads. However, some UV lamps in the existing technology are fixed and have limited freedom of movement. They can only irradiate at a fixed angle to a large extent. For irregularly shaped modules or large modules, it is impossible to achieve the optimal UV irradiation position, which leads to a significant decrease in UV effect or an increase in UV time, ultimately resulting in poor irradiation effect.

[0023] This specific embodiment is a fixed-point FPC board UV adhesive curing device, the structural schematic diagram of which is shown below. Figures 1-5 As shown, the curing device includes a frame 1, a workbench 2 fixedly mounted on the top of the frame 1, a frame 3 slidably mounted on the workbench 2, a UV lamp head 4 disposed inside the frame 3, an angle adjustment component 5 for changing the angle of the UV lamp head 4 installed inside the frame 3, an height adjustment component 6 for changing the height of the UV lamp head 4 also installed on the frame 3, and a linear motor 7 for driving the frame 3 and the UV lamp head 4 to move is mounted on the frame 1.

[0024] This invention enables the UV lamp head 4 to be angled via the angle adjustment component 5. Simultaneously, the height adjustment component 6 drives the angle adjustment component 5 and the UV lamp head 4 to rise and fall synchronously. Furthermore, the linear motor 7 drives the frame 3, height adjustment component 6, angle adjustment component 5, and UV lamp head 4 to move synchronously. This allows the UV lamp head 4 to be flexibly adjusted according to the position of the glued connector, thus enabling better timed irradiation of the glued connector, ensuring the UV adhesive reaches the set radiation level and protecting the connector solder joints.

[0025] The height adjustment assembly 6 includes a lifting frame 601 slidably installed inside the frame 3, nut seats 602 fixedly installed at the four corners of the lifting frame 601, a threaded rod 603 threadedly installed inside the nut seat 602, a rotating rod 604 fixedly installed on the top of the threaded rod 603, a sprocket 605 fixedly installed on the outer surface of the rotating rod 604, and a chain 606 meshing with the sprocket 605.

[0026] The bottom end of the threaded rod 603 is rotatably mounted on the inner top wall of the frame 3 via a bearing, and the rotating rod 604 is rotatably mounted on the frame 3 via a bearing. A handwheel 607 is fixedly mounted on one of the rotating rods 604. Under the action of the handwheel 607, it is convenient for the staff to rotate the threaded rod 603, which makes it convenient for the staff to operate the height adjustment component 6.

[0027] When the operator turns the handwheel 607 clockwise, the handwheel 607 drives the rotating rod 604 fixedly installed with it to rotate. During the rotation, the rotating rod 604 drives the sprocket 605 fixedly installed with it to rotate. During the rotation of the sprocket 605, the sprocket 605 drives the chain 606 to rotate. During the rotation of the chain 606, the chain 606 drives the other sprockets 605 meshing with it to rotate synchronously. This causes the rotating rods 604 at the four corners of the lifting frame 601 to rotate synchronously. During the rotation of the rotating rod 604, the threaded rod 603 fixedly installed with it to rotate. During the rotation of the threaded rod 603, the nut seat 602 threadedly installed with it to move upward. During the upward movement of the nut seat 602, the lifting frame 601 fixedly installed with it to move upward. During the upward movement of the lifting frame 601, the angle adjustment component 5 and the UV lamp head 4 move upward synchronously.

[0028] Similarly, when the staff turns the handwheel 607 counterclockwise, it can drive the angle adjustment component 5 and the UV lamp head 4 to move downwards simultaneously.

[0029] Therefore, the height of the angle adjustment component 5 and the UV lamp head 4 can be adjusted by the height adjustment component 6.

[0030] A scale 608 is fixedly installed on the front of the frame 3, and a first pointer 609 is fixedly installed on the front of the lifting frame 601. With the cooperation of the first pointer 609 and the scale 608, the height of the angle adjustment component 5 and the UV lamp head 4 can be indicated.

[0031] The angle adjustment component 5 includes two overlapping plates 501 fixedly installed on the front and rear sides of the lifting frame 601, a UV lamp head mounting plate 502 rotatably installed between the two overlapping plates 501, and a rotary cylinder 503 that drives the UV lamp head mounting plate 502 to rotate. The UV lamp head 4 is fixedly installed on the UV lamp head mounting plate 502. An angle ruler 504 is fixedly installed on the front of the UV lamp head mounting plate 502. The rotary cylinder 503 drives the UV lamp head mounting plate 502 to rotate. During the rotation, the UV lamp head mounting plate 502 can drive the UV lamp head 4 to rotate, thereby achieving the desired angle of the UV lamp head 4.

[0032] A second pointer 505 is also fixedly installed on the front of the lifting frame 601. With the cooperation of the angle ruler 504 and the second pointer 505, it can indicate the angle adjustment of the UV lamp head 4.

[0033] At least one blower motor 8 is fixedly installed on the lifting frame 601.

[0034] A sliding block 9 is fixedly installed at the bottom of the frame 3, and a slide rail 10 that cooperates with the sliding block 9 is fixedly installed at the top of the worktable 2. The sliding block 9 is slidably installed on the slide rail 10. Under the action of the linear motor 7, the frame 3 can be driven to move. During the movement, the frame 3 can drive the height adjustment component 6, the angle adjustment component 5 and the UV lamp head 4 to move synchronously. During the movement, the frame 3 drives the sliding block 9 to slide on the slide rail 10. With the cooperation of the sliding block 9 and the slide rail 10, the movement of the frame 3 can be guided, so that the frame 3, the height adjustment component 6, the angle adjustment component 5 and the UV lamp head 4 move more smoothly.

[0035] In summary, this utility model enables the UV lamp head 4 to be angled via the angle adjustment component 5. Simultaneously, the height adjustment component 6 drives the angle adjustment component 5 and the UV lamp head 4 to move synchronously. Furthermore, the linear motor 7 drives the frame 3, height adjustment component 6, angle adjustment component 5, and UV lamp head 4 to move synchronously. This allows the UV lamp head 4 to be flexibly adjusted according to the position of the glued connector, thus enabling better timed irradiation of the glued connector, ensuring the UV adhesive reaches the set radiation level and protecting the connector solder joints.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
