Description

Technical Field

[0001] This utility model relates to the field of lamp panel correction, specifically a device for correcting warping of mini lamp panels. Background Technology

[0002] The PCB material commonly used in laptops, tablets, automotive, and industrial control Mini LED boards is FR-4 with a thickness of 0.4T. After reflow soldering using fixtures during the SMT production process, the LED boards may exhibit various warping phenomena, such as bowl warping, diagonal warping, and turtle warping. This warping can lead to defects and losses due to exceeding the standard. Therefore, it is necessary to correct the warped LED boards, which requires the use of correction devices.

[0003] Existing correction devices require manual correction of the lamp panel, with manual visual inspection of the degree of warping. However, manual inspection is prone to errors. Then, the lamp panel is tied to a horizontal wooden board with rope, and the tied wooden board is then baked again. However, this method is quite cumbersome. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a device for correcting warping of mini lamp panels, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for correcting warping of mini lamp panels, comprising a base, a support platform mounted on the top of the base, and side plates movably mounted on both sides of the top of the base. Multiple sets of fixing plates are fixed to one side of each side plate, and two sets of pressure plates are movably mounted on the top of each side plate. A limiting component is movably mounted above the side plate to limit the pressure plates and prevent them from moving. A lead screw is movably mounted inside the base, and a first limiting block is sleeved on the outer wall of the lead screw, and the first limiting block is fixedly connected to the side plate.

[0006] By adopting the above technical solution, the purpose of correcting the warping of the lamp panel is achieved. When the lamp panel needs to be corrected, first adjust the distance between the two sets of side plates to a suitable length according to the length of the lamp panel. Then place the warped lamp panel on top of the fixed plate and the support platform. Then flip the pressure plate, which will correct the warped lamp panel and correct both ends of the lamp panel. Then rotate the limiting component, which will lock into the pressure plate to prevent the pressure plate from shaking and causing the correction to fail.

[0007] The present invention is further configured such that indicator plates are fixed on both sides of the side plate, and a scale is provided on the top of the base.

[0008] Preferably, the indicator plate can work in conjunction with a ruler to facilitate observation of the movement distance of the side plate, thereby enabling correction for light plates of different models and sizes.

[0009] The present invention is further configured such that a second limiting block is fixed at the bottom of the side plate, and a sliding groove matching the first limiting block and the second limiting block is provided at the top of the base.

[0010] Preferably, the second limiting block can further limit the side plate, and the sliding groove can conveniently limit the movement direction of the side plate, so that the side plate slides directionally above the base.

[0011] The present invention is further configured such that a handle is fixed to the end of the lead screw, and the lead screw is threadedly connected to the first limiting block.

[0012] Preferably, the screw is designed with a handle to allow for easy rotation by a person.

[0013] The present invention is further configured such that a groove is provided on one side of the pressure plate, and a protrusion is fixed on one side of the pressure plate, and the cross-section of the protrusion is semi-circular.

[0014] Preferably, the contact area between the pressure plate and the lamp plate can be reduced by the groove and the semi-circular raised section.

[0015] The present invention is further configured such that the limiting component includes a blocking plate movably mounted on the top of the side plate, and the blocking plate is connected to the side plate via a damping pivot.

[0016] Preferably, the pressure plate can be limited by the setting of the limiting component to avoid the pressure plate flipping over due to the force exerted by the lamp plate on the pressure plate when the pressure plate is pressing on the lamp plate.

[0017] The present invention is further provided that a rotating groove is provided on the top of the side plate.

[0018] Preferably, the slotted groove allows for easy storage of the baffle plate, preventing it from being left exposed on the outside when not in use, which would make it inconvenient to place the light panel.

[0019] The present invention is further configured such that a connecting rod is fixed between the two sets of pressure plates, and the two sets of pressure plates are on the same plane.

[0020] Preferably, the connecting rod can cause the other set of pressure plates to flip when one set of pressure plates flips, so that the two sets of pressure plates flip simultaneously. This eliminates the need for personnel to flip the other set of pressure plates, making the operation of the two sets of pressure plates more stable and improving the correction effect on the lamp panel.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model, by providing side plates, lead screws, a first limiting block, a support platform, a fixing plate, and a pressure plate, achieves the purpose of facilitating the correction of lamp panel warping. When the lamp panel needs to be corrected, first adjust the distance between the two sets of side plates to a suitable length according to the length of the lamp panel. Then, place the warped lamp panel above the fixing plate and the support platform. Subsequently, flip the pressure plate, which corrects the warped lamp panel and straightens both ends of the lamp panel. Then, rotate the limiting component, which engages above the pressure plate to prevent the pressure plate from shaking and causing correction failure.

[0023] 2. This utility model is equipped with an indicator plate, a second slider, a scale, and a slide groove. The indicator plate and the scale work together so that when the side plate moves, the indicator plate moves with it. The moving indicator plate moves to one side of the scale, allowing the distance the side plate moves to be observed. This allows for adjustments to different sizes and models of light panels, making the adjustments more accurate. The slide groove further limits the movement of the side plate.

Two sets of pressure plates 5 are movably mounted on the top of the side plates 2. The pressure plates 5 press the ends of the lamp panel to keep the lamp panel horizontal. A limiting component is movably mounted on the top of the side plates 2. The limiting component can limit the pressure plates 5 to prevent them from flipping. The limiting component is used to limit the pressure plates 5 to prevent them from moving. A lead screw 8 is movably mounted inside the base 1. A first limiting block 21 is sleeved on the outer wall of the lead screw 8 and is fixedly connected to the side plates 2.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 Indicator plates 11 are fixed on both sides of the side plate 2, and a scale 4 is provided on the top of the base 1. The indicator plates 11 can cooperate with the scale 4 to facilitate observation of the movement distance of the side plate 2, thereby enabling correction for lamp plates of different models and sizes.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 The bottom of the side plate 2 is fixed with a second limiting block 22, and the top of the base 1 is provided with a sliding groove 7 that matches the first limiting block 21 and the second limiting block 22. The second limiting block 22 can further limit the side plate 2, and the sliding groove 7 can conveniently limit the movement direction of the side plate 2, so that the side plate 2 can slide directionally above the base 1.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A handle 81 is fixed to the end of the lead screw 8, and the lead screw 8 is threadedly connected to the first limit block 21. The handle 81 allows personnel to easily rotate the lead screw 8.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A groove 52 is provided on one side of the pressure plate 5, and a protrusion 51 is fixed on one side of the pressure plate 5. The cross-section of the protrusion 51 is semi-circular. By providing the groove 52 and the semi-circular cross-section of the protrusion 51, the contact area between the pressure plate 5 and the lamp plate can be reduced.

[0038] For details regarding the above embodiments, please refer to [link / reference].

Figure 5 A connecting rod 53 is fixed between the two sets of pressure plates 5, and the two sets of pressure plates 5 are on the same plane. The connecting rod 53 can drive the other set of pressure plates 5 to flip when one set of pressure plates 5 flips, so that the two sets of pressure plates 5 flip at the same time. There is no need for personnel to flip the other set of pressure plates. The two sets of pressure plates 5 will work more stably and have a better correction effect on the lamp board.

[0041] In practical operation, this invention works as follows: First, adjust the distance between the side plates 2. Then, rotate a set of handles 81. Rotating the handles 81 will cause the lead screw 8 to rotate. According to the lead screw principle, the rotation of the lead screw 8 will cause the first limiting block 21 to slide on the inner wall of the slide groove 7. When the first limiting block 21 slides on the inner wall of the slide groove 7, it will cause the side plates 2 to move. The movement of the side plates 2 will cause the indicator plate 11 to move. Under the action of the indicator plate 11 and the scale 4, the position of the side plates 2 is adjusted. After the position of the side plates 2 is adjusted, The lamp panel is placed above the fixing plate 10 and the support platform 3. Then, the pressure plate 5 is flipped over, pressing one end of the lamp panel tightly. Then, the blocking plate 6 is rotated, and the bottom of the blocking plate 6 fits against the top of the pressure plate 5. Then, another set of pressure plates 5 is flipped over, and the pressure plates 5 are flipped over to clamp the other end of the lamp panel, so that the bottom of the lamp panel is on the same horizontal plane, achieving the purpose of correcting the lamp panel. After fixing, it is placed in the oven for baking. The oven temperature is 90 degrees (the product temperature can be adjusted according to different materials). After baking, the warped product is left to rest for 4-8 hours to correct and restore its flatness.
