Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a fixture for combining a lamp strip and a light guide plate. Background Technology

[0002] In backlight modules or lighting equipment, light strips must be tightly fitted to light guide plates to ensure efficient light transmission. The fixture used to press the light strips and light guide plates together is a tool or device specifically designed to precisely and efficiently combine the light strips and light guide plates. It achieves a tight fit between the light strips and light guide plates through appropriate pressure.

[0003] However, existing fixtures for pressing light strips and light guide plates have certain limitations in use. When pressing the light strip and light guide plate together, the lamp body extends beyond the edges of the light strip, and the lamp body is easily subjected to more pressure than the edges of the light strip. This can easily damage the lamp body during pressing, affecting the performance of the product. Moreover, in practical applications, the width of the light strip and the lamp body on the light strip varies. A fixed placement position can only accommodate light strips of a specific width and cannot meet the needs of light strips of different widths. Therefore, a fixture for pressing light strips and light guide plates is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where, during the pressing of light strips and light guide plates, the lamp body portion extends beyond the edges of the light strip, making it susceptible to excessive pressure. This pressure can easily damage the lamp body portion during pressing, affecting product performance. Furthermore, in practical applications, light strips and their lamp body portions come in various widths, and fixed placement positions can only accommodate light strips of specific widths, failing to meet the needs of light strips of different widths. Therefore, this invention proposes a fixture for pressing light strips and light guide plates to solve these problems.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A fixture for assembling a light strip and a light guide plate includes:

[0007] The enclosure comprises a housing, pressing rollers, and a light strip placement block. The pressing rollers are mounted on the top of the housing via a driving device.

[0016] Preferably, a suction cup is fixedly provided on the outer wall of the box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by setting the connection relationship between the housing, the light strip placement block, the placement groove, the moving block, the rotating shaft, and the adjusting shaft, the operator can rotate the adjusting shaft to make the transmission gear push the transmission rack to drive the sliding block and the moving block to move backward, so that the width of the placement groove can be adjusted.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example: This example provides a fixture for combining a light strip and a light guide plate. See [link to example]. Figure 1-6 Specifically, including:

[0031] The enclosure 1 comprises a pressing roller 102 and a light strip placement block 2. The pressing roller 102 is mounted on the top of the enclosure 1 via a drive device. The light strip placement block 2 is fixedly mounted on the top of the enclosure 1. A light guide plate placement block 101 is located on the top of the enclosure 1. The light guide plate is positioned by being attracted to the top of the light guide plate placement block 101 via a negative pressure system. The top of the light strip placement block 2 has a placement groove 201 for placing the light body. By placing the light body portion of the light strip in the placement groove 201, the pressure on the light body during pressing of the light strip and light guide plate by the pressing roller 102 is reduced, thus preventing damage to the light body. The top of the light strip placement block 2 has a moving component, which includes:

[0032] The movable block 3 has a sliding block 302 fixedly installed at its bottom. The top of the light strip placement block 2 has a movable opening 202, and the bottom of the sliding block 302 is movably inserted into the movable opening 202. There are two sets of movable openings 202 and sliding blocks 302, which are symmetrically distributed to ensure the smooth operation of the components.

[0033] The rotating shaft 4 and the transmission gear 401 are fixedly mounted on the outer wall of the rotating shaft 4. One end of the rotating shaft 4 is rotatably connected to the inner cavity of the lamp strip placement block 2 via a bearing. The outer wall of the transmission gear 401 is meshed with a transmission rack 303, which is fixedly mounted on the top of the slide rod 304. In use, rotating the rotating shaft 4 backward causes the transmission gear 401 to rotate backward, which in turn causes the outer wall of the transmission gear 401 to press and push the transmission rack 303, causing the transmission rack 303 to move backward. The backward movement of the transmission rack 303 drives the sliding block 302 to move backward, which in turn drives the moving block 3 to move backward. This allows the width of the placement groove 201 to be adjusted, facilitating the self-adjustment of the width of the lamp strip body to be pressed as needed. This flexibly adapts to lamp strips of various widths, improves the versatility and compatibility of the fixture, helps reduce errors during assembly, and improves processing efficiency.

[0034] The outer wall of the light strip placement block 2 has a round hole. The other end of the rotating shaft 4 extends outward through the round hole in the outer wall of the light strip placement block 2 and is fixedly mounted with an adjustment shaft 5, which is used to extend the action point of the rotating shaft 4 for easy adjustment and control by the user.

[0035] A fixing plate 502 is fixedly installed on the outer wall of the light strip placement block 2. The outer wall of the fixing plate 502 has a threaded groove, and a screw 503 is threadedly connected to the inner wall of the threaded groove. One end of the screw 503 is rotatably connected to the fixing block 504 through a bearing. In use, when the moving block 3 moves to the corresponding position according to the light body part of the light strip, the rotation of the adjusting shaft 5 stops. At this time, by rotating the screw 503, the screw 503 moves in the direction of the adjusting shaft 5. The moving screw 503 drives the fixing block 504 to move, so that the fixing block 504 presses and abuts against the outer wall of the adjusting shaft 5, thereby restricting the adjusting shaft 5 to this position and fixing the application position of the moving block 3.

[0036] The outer wall of the fixing plate 502 has a circular hole, and a rod 506 is movably inserted into the inner wall of the circular hole on the outer wall of the fixing plate 502. One end of the rod 506 is fixedly connected to the outer wall of the fixing block 504. By restricting the sliding of the rod 506 in the circular hole on the outer wall of the fixing plate 502, the movement path and movement range of the fixing block 504 are restricted.

[0037] A triangular block 505 is fixedly installed at the other end of the screw 503 to facilitate user operation and adjustment. A silicone pad 501 is fixedly adhered to the outer wall of the adjusting shaft 5 to increase the friction between the outer wall of the adjusting shaft 5 and the fixed block 504, thereby improving the tightness and stability.

[0038] The inner cavity of the light strip placement block 2 is provided with a sliding groove 203. A sliding rod 304 is movably engaged with the inner wall of the sliding groove 203, and the sliding rod 304 is fixedly set on the outer wall of the transmission rack 303, which restricts the movement range and movement path of the transmission rack 303.

[0039] The top of the movable block 3 is fixedly provided with an anti-slip pad 301. There are two sets of anti-slip pads 301, and the other set is provided on the top of the light strip placement block 2, that is, on both sides of the placement groove 201, to increase the friction with the edges of the light strip, so as to facilitate the pressing roller 102 to press the light guide plate and the light strip.

[0040] A suction cup 6 is fixedly installed on the outer wall of the housing 1. The suction cup 6 is attached to the worktable to further improve the stability of the housing 1 and facilitate the subsequent pressing and processing of the light guide plate and the light strip.

[0041] Specifically, the working principle and operation method of this utility model are as follows:

[0042] In use, the operator rotates the adjusting shaft 5 backward, which in turn drives the rotating shaft 4 to rotate backward. This causes the rotating shaft 4 to drive the transmission gear 401 to rotate backward, which in turn causes the outer wall of the transmission gear 401 to press and push the transmission rack 303, causing the transmission rack 303 to move backward. The backward movement of the transmission rack 303 drives the sliding block 302 to move backward, which in turn drives the moving block 3 to move backward. This allows the width of the placement groove 201 to be adjusted, making it easy to adjust the width of the lamp strip and lamp body to be pressed as needed. This allows for flexible adaptation to lamp strips of various widths, improves the versatility and compatibility of the fixture, helps reduce errors during assembly, and improves processing efficiency.

[0043] When in use, after the moving block 3 moves to the corresponding position according to the lamp body part of the light strip, the rotation of the adjusting shaft 5 is stopped. At this time, by rotating the screw 503, the screw 503 moves in the direction of the adjusting shaft 5. The moving screw 503 drives the fixed block 504 to move, so that the fixed block 504 is pressed and pressed against the outer wall of the adjusting shaft 5, thereby restricting the adjusting shaft 5 to this position, and thus fixing the application position of the moving block 3. It is then adsorbed on the worktable by the suction cup (6), which further improves the stability of the box (1) and facilitates the subsequent pressing and processing of the light guide plate and the light strip.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
