As a critical component of the backlight module, the proper fit of the light strips directly impacts the quality of the backlight module. Improper fit can result in light leakage from the backlight module. Therefore, during backlight module assembly, it's essential to further verify the tightness of the connection between the light strips and the backplate. Utility Model Content

[0003] The purpose of the utility model is to provide a pressing fixture, which further improves the tightness of the connection between the light strip and the backboard, prevents the backlight module from leaking light in the finished picture state, and ensures the product quality of the backlight module.

[0004] A pressing jig includes a carrier substrate and a pressing assembly arranged on the carrier substrate, the pressing assembly is rotatably connected to the carrier substrate, the carrier substrate is provided with a positioning groove, the positioning groove is used to place a back panel with a light bar attached, the pressing assembly includes a push plate and at least one driving member, the output end of the driving member is connected to the push plate, the pressing assembly can be rotated to the top of the positioning groove and make the push plate opposite to the light bar, and the driving member can drive the push plate to move horizontally to approach or move away from the light bar.

[0005] In the above technical solution, the carrier substrate is provided with a positioning groove. When in use, the back panel with the light bar attached is placed in the positioning groove to ensure that the back panel can remain stably placed during the pressing process to avoid the back panel moving and affecting the pressing quality. The pressing assembly is provided on the carrier substrate and is rotatably connected to the carrier substrate to facilitate the operator to take and place the back panel. Specifically, when in use, the pressing assembly is turned over, and then the back panel with the light bar attached is placed in the positioning groove. At the same time, the pressing assembly is reset so that the pressing assembly is rotated to the top of the positioning groove and the push plate is opposite to the light bar. After the pressing is completed, the pressing assembly is turned over again so that the operator can quickly and accurately remove the back panel. The rotational connection between the pressing assembly and the carrier substrate improves the safety of the light bar and the back panel during the pressing process. The utility model further presses the light bar and the back panel by providing a pressing assembly and a positioning groove, thereby improving the tightness of the connection between the light bar and the back panel, preventing the backlight module from leaking light in the finished picture state, and ensuring the product quality of the backlight module.

[0006] Furthermore, the size of the positioning groove matches the size of the back plate.

[0007] In this technical solution, the matching design of the positioning slots and backsheet dimensions ensures the backsheet is accurately positioned within the slots during the press-fit process, thus avoiding issues such as inaccurate press fit or defective products caused by misalignment. Furthermore, the operator can intuitively determine whether the backsheet is correctly positioned within the slots, eliminating the need for complex adjustment or calibration steps and reducing operational complexity.

[0008] Furthermore, the supporting substrate is provided with openings on both sides close to the length direction of the positioning groove.

[0009] In this technical solution, operators can quickly position the fixture by simply inserting the backing plate along the opening, eliminating the need for precise alignment or adjustment. The opening also makes the interior of the positioning slot easier to clean, helping to maintain a clean and hygienic fixture.

[0010] Furthermore, the groove wall of the positioning groove is recessed inward to form a plurality of first avoidance grooves arranged at intervals.

[0011] In the above technical solution, the design of the first avoidance groove prevents the positioning groove from interfering with certain structures of the back plate, while ensuring that certain protruding parts of the back plate will not be damaged due to excessive pressure during the pressing process.

[0012] Furthermore, avoidance holes are provided at the corners of the positioning grooves.

[0013] In the above technical solution, the design of the avoidance holes prevents the back panel from being impacted and affecting its corners during lamination, thereby ensuring the back panel's aesthetics. Furthermore, during use, the jig can use the avoidance holes and fasteners such as pins to secure the carrier substrate to other structures, ensuring stable lamination.

[0014] Furthermore, a buffer pad is provided on the side of the push plate facing away from the driving member.

[0015] In the above technical solution, a buffer pad is provided on the side of the push plate away from the driving member, which can reduce the impact and damage to the light bar or back plate during the pressing process, improve the protection performance of the product, and reduce the defective product rate.

[0016] Furthermore, a plurality of second avoidance grooves arranged at intervals are provided on a side of the buffer pad facing away from the push plate.

[0017] In the above technical solution, the design of the second avoidance groove enables the buffer pad to avoid interference with the lamp beads on the light bar. During the pressing process, these lamp beads can be embedded in the second avoidance groove, thereby avoiding damage or crushing to the light bar.

[0018] Furthermore, a mounting plate is connected between the driving member and the push plate.

[0019] In the above technical solution, the mounting plate serves as a connecting member between the driving member and the push plate, which can enhance the structural stability of the entire pressing assembly, ensure that the push plate can move smoothly and accurately when driven by the driving force of the driving member, and reduce vibration and deviation caused by structural instability.

[0020] Furthermore, the pressing assembly further includes a bracket, the bracket is rotatably connected to the supporting substrate, the bracket is provided with a receiving cavity, and the driving member is provided in the receiving cavity.

[0021] In the above technical solution, the bracket is rotatably connected to the carrier substrate, meaning that the bracket can rotate or pivot on the carrier substrate to adjust the direction or position of the push plate. The bracket is provided with a receiving cavity for accommodating the driver, protecting the driver from external interference while ensuring stable operation.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The carrier base plate is equipped with a positioning groove, which is used to place the back plate with the light strip attached to prevent the back plate from moving during pressing, which would affect the pressing quality. When in use, place the back plate with the light strip attached into the positioning groove and then press it. The positioning groove acts as a limiter to ensure that when the push plate moves horizontally, the light strip is always opposite to the push plate, allowing the push plate to further press the light strip and the back plate, improving the connection tightness between the light strip and the back plate.

[0024] 2. The pressing assembly is rotatably connected to the carrier substrate. The carrier substrate serves as the foundation of the entire fixture and plays a supporting role. The pressing assembly provides the force required to press the light strip and the back panel together. The rotatable connection between the pressing assembly and the carrier substrate means that the pressing assembly can be rotated or adjusted to a certain extent on the carrier substrate, making it easier for operators to remove and place the back panel. When placing or removing the back panel, the pressing assembly is flipped by rotating it and away from the back panel. At this time, the operator has more space to remove and place the back panel, avoiding damage to the back panel during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will further describe the pressing fixture of the present invention in detail with reference to specific embodiments and accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0033] Please refer to Figure 1 In a preferred embodiment, the pressing jig of the present invention includes a carrier substrate 1 and a pressing assembly 2 provided on the carrier substrate 1. The pressing assembly 2 is rotatably connected to the carrier substrate 1. The carrier substrate 1 is provided with a positioning groove 101. The positioning groove 101 is used to place the back panel with the light bar attached thereto. The pressing assembly 2 includes a push plate 201 and at least one driving member 202. The output end of the driving member 202 is connected to the push plate 201. The pressing assembly 2 can be rotated to the top of the positioning groove 101 and make the push plate 201 opposite to the light bar. The driving member 202 can drive the push plate 201 to move horizontally to approach or move away from the light bar.

[0034] In this embodiment, the pressing assembly 2 is arranged above part of the positioning groove 101, and the carrier substrate 1 is provided with a positioning groove 101. When in use, the back panel with the light bar attached is placed in the positioning groove 101. The setting of the positioning groove 101 can ensure that the back panel can remain stably placed during the pressing process, and prevent the back panel from moving and affecting the pressing quality. The pressing assembly 2 is arranged on the carrier substrate 1 and is rotatably connected to the carrier substrate 1. The design of the rotatable connection between the pressing assembly 2 and the carrier substrate 1 makes it easy for the operator to take and place the back panel. Specifically, when in use, the pressing assembly 2 is flipped over, and then the back panel with the light bar attached is placed in the positioning groove 101, and the pressing assembly 2 is reset at the same time, so that the pressing assembly 2 is rotated to the top of the positioning groove 101 and the push plate 201 is opposite to the light bar. After the pressing is completed, the pressing assembly 2 is flipped over so that the operator can quickly and accurately remove the back panel. The rotatable connection between the pressing assembly 2 and the carrier substrate 1 improves the safety of the light bar and the back panel during the pressing process. The utility model further presses the light bar and the back plate by providing the pressing component 2 and the positioning groove 101, thereby improving the tightness of the connection between the light bar and the back plate, preventing the backlight module from leaking light in the finished picture state, and ensuring the product quality of the backlight module.

[0035] In this embodiment, two driving members 202 are provided, and the output ends of the two driving members 202 are respectively connected to the push plate 201, so that the push plate 201 can be more stable when moving horizontally. At the same time, the setting of the two driving members 202 can provide a more stable pressing force, further ensuring the tightness of the connection between the light bar and the back plate. It should be noted that the number of driving members 202 can also be set to three, five or more. The present embodiment uses a cylinder as a power source, and the cylinder controls the air inlet and outlet valves to achieve control of parameters such as speed, torque and position. On an automated production line, the precise control capability of the cylinder can ensure the accurate positioning of mechanical components, thereby improving product quality and production efficiency. The movement of the push plate 201 can also be fully automatically driven by a linear motor, an electric push rod, etc., without the need for manual push, to achieve automated operation.

[0036] Furthermore, the size of the positioning groove 101 matches the size of the back panel. The design of the positioning groove 101 matching the size of the back panel ensures that the back panel can be accurately placed in the positioning groove 101 during the pressing process, thereby avoiding the problem of inaccurate pressing or defective products due to position offset. At the same time, the back panel can remain stable in the positioning groove 101 of matching size, avoiding movement or tilting due to external force or vibration during the pressing process, reducing the risk of damage to the back panel, and ensuring the stability and consistency of the pressing process. At the same time, the operator can intuitively judge whether the back panel has been correctly placed in the positioning groove, without the need for complicated adjustment or calibration steps, reducing the difficulty of operation.

[0037] Please refer to Figure 1 The carrier substrate 1 has openings 1011 on both sides of the length of the positioning groove 101. The design of openings 1011 eliminates the need for precise alignment or adjustment when placing the backplane. Operators can simply insert the backplane along the direction of openings 1011 for quick positioning, reducing operational difficulty. Operators can also remove and place the backplane through openings 1011, ensuring that the backplane can be quickly and stably placed in the positioning groove 101. Furthermore, openings 1011 make the interior of the positioning groove 101 easier to clean, helping to maintain the cleanliness and hygiene of the jig.

[0038] Please refer to Figure 2 The groove wall of the positioning groove 101 is recessed inward to form a plurality of first avoidance grooves 1012 arranged at intervals. Different back panels may have different design elements, such as protrusions, grooves, wiring holes, etc. The first avoidance grooves 1012 can accommodate these design elements, so that the jig can be applied to a wider variety of back panels. At the same time, the presence of the first avoidance grooves 1012 can ensure that during the pressing process, the push plate 201 can accurately act on the area that needs to be pressed, avoiding inaccurate pressing caused by interference from design elements on the back panel.

[0039] Please refer to Figure 2The corners of the positioning grooves 101 are provided with avoidance holes 1013. The design of the avoidance holes 1013 allows the back panel to extend into the avoidance holes 1013 when subjected to the pressing force during pressing, preventing damage to the corners of the back panel and affecting its aesthetics. Furthermore, when the jig is in use, the avoidance holes 1013 and fasteners such as pins can be used to secure the carrier substrate 1 to other structures, ensuring stable pressing.

[0040] Please refer to Figure 1 A buffer pad 3 is provided on the side of the push plate 201 facing away from the driver 202. This cushion pad 3 reduces impact and damage to the light bar or back panel during the pressing process, preventing damage or deformation of the light bar and back panel due to excessive pressure. This improves product protection and reduces defective product rates. Furthermore, the elasticity of the cushion pad 3 ensures that the push plate 201 applies even pressure to the light bar and back panel during the pressing process, preventing uneven pressure distribution or localized excessive pressure, thereby improving the quality and consistency of the pressing process.

[0041] Specifically, the side of the cushion pad 3 facing away from the push plate 201 is provided with a number of spaced-apart second avoidance grooves 301. The design of these second avoidance grooves 301 prevents the cushion pad 3 from interfering with the light beads on the light bar. During the pressing process, these light beads can be embedded in the second avoidance grooves 301, thus preventing damage or crushing to the light bar. Furthermore, the design of these second avoidance grooves 301 allows the cushion pad 3 to better conform to the surface of the light bar, reducing pressing errors caused by uneven or protruding surfaces, thereby improving the accuracy and consistency of the pressing operation.

[0042] Please refer to Figure 3 A mounting plate 4 is connected between the driver 202 and the push plate 201. As a connector between the driver 202 and the push plate 201, the mounting plate 4 enhances the structural stability of the entire press-fit assembly 2, ensuring that the push plate 201 moves smoothly and accurately when driven by the driver 202, thereby reducing vibration and deflection caused by structural instability. Furthermore, the mounting plate 4 acts as a buffer and stress dissipator between the driver 202 and the push plate 201. During the press-fit process, the mounting plate 4 absorbs some vibration and impact, reducing direct wear between the driver 202 and the push plate 201 and lowering the failure rate.

[0043] Please refer to Figure 1In this embodiment, the pressing assembly 2 further includes a bracket 203, which is rotatably connected to the carrier substrate 1. The bracket 203 defines a receiving cavity 2031, and the driving member 202 is disposed within the receiving cavity 2031. The rotatable connection between the bracket 203 and the carrier substrate 1 allows the bracket 203 to rotate or pivot on the carrier substrate 1, thereby adjusting the direction or position of the push plate 201. The bracket 203 defines a receiving cavity 2031 for accommodating the driving member 202, protecting the driving member 202 from interference from the external environment while also ensuring stable operation of the driving member 202.
