Description

Technical Field

[0001] This utility model relates to the technical field of back panel processing devices, and in particular to a back panel processing device for a display. Background Technology

[0002] As a core supporting component of display devices, the display backplate not only fixes the internal circuit boards and electronic components, but also directly affects the stability and long-term reliability of the overall structure. With the rapid development of display technology towards thinner, larger, and more integrated designs, the size range of display backplates continues to expand, from small and medium-sized automotive display backplates to ultra-large-sized television display backplates. Therefore, a dedicated processing device is needed that can flexibly accommodate the processing needs of backplates of different specifications while ensuring positioning accuracy and clamping stability.

[0003] Traditional display backplate processing devices rely on a single set of sliding rods for unidirectional clamping, lack a longitudinal clamping structure, and are prone to transmission deviation, making it impossible to form a longitudinal limit for the backplate. Furthermore, they depend on fixed locking holes, the clamping force adjustment is discontinuous, and it is difficult to flexibly adapt to the backplate material or thickness.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN220145722U that discloses a processing device for a liquid crystal display back panel. The patent states that "in use, the display back panel to be processed is placed on a flat plate, and the motor is started. The motor's output shaft drives a sliding rod to rotate. When the sliding rod rotates, the positioning rail limits the positioning plate, allowing the sliding rod to move only along the grooves on the surface of the sliding rod. Because the surface of the sliding rod has opposite grooves, the sliding rod moves towards the center. Simultaneously, a block pushes a movable clamping plate to clamp the display back panel. When the motor continues to rotate, the clamping rod moves downwards and engages with the locking holes on the surface of the positioning rail, preventing the sliding rod from moving and achieving maximum clamping force, thus preventing excessive clamping force from deforming the display back panel." However, this device achieves bidirectional horizontal clamping by driving the sliding rod with the sliding rod, but it cannot provide longitudinal limitation for the back panel.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this utility model is to provide a back panel processing device for a display, so as to solve the shortcomings of the traditional back panel processing device for displays mentioned in the background art, which relies on a single set of sliding rods to achieve unidirectional clamping, lacks a longitudinal clamping structure, and is prone to transmission deviation, and cannot form a longitudinal limit for the back panel. In addition, it relies on fixed card holes for locking, the clamping force adjustment is discontinuous, and it is difficult to flexibly adapt to the back panel material or thickness.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a back panel processing device for a display, comprising a base, a worktable fixedly mounted on the upper end of the base, rotating rods fixedly connected through both ends of the worktable, a rotating ring sleeved on the outer ring of the rotating rod, a pulley fixedly mounted on the front end of the rotating ring, a slide frame sleeved on the outer ring of the pulley, a push rod fixedly mounted on the front end of the slide frame, a connecting ring sleeved on the outer ring of the push rod, a limiting ring sleeved on the outer ring of the push rod, a push plate sleeved on the outer ring of the connecting ring, a limiting block fixedly mounted on the upper end of the base, support rods fixedly mounted through both ends of the push plate, a fixing ring fixedly mounted on the rear end of the support rod, a spring sleeved on the outer ring of the support rod, a first longitudinal clamping plate fixedly mounted on the front end of the support rod, and a second mounting plate fixedly mounted on the upper end of the base, with a second longitudinal clamping plate at the front end of the second mounting plate.

[0008] Preferably, the lower end of the limiting ring is fixedly connected to the base, and the push plate is connected to the first longitudinal clamping plate by a spring.

[0009] Preferably, a guide rail is fixedly installed at the lower end of the worktable, and a slider is fixedly installed at the upper end of the guide rail. Both ends of the slider are connected by ball screws.

[0010] Preferably, a connecting block is fixedly installed at the upper end of the slider, a slide groove is provided at the upper end of the worktable, a first mounting plate is fixedly installed at the upper end of the connecting block, and a first transverse clamping plate is provided at the front end of the first mounting plate.

[0011] Preferably, a third mounting plate is fixedly installed on the upper end of the workbench, and a second transverse clamp is provided at the front end of the third mounting plate.

[0012] Preferably, a mounting base is fixedly installed on the upper end of the base, a processing arm is fixedly installed on the upper end of the mounting base, and a processing fixture is provided on the upper end of the mounting base.

[0013] Preferably, a drive motor is provided at the upper end of the base, the output end of the drive motor is connected to a belt through a synchronous pulley, the belt is connected to a reducer through another set of synchronous pulleys, and the output end of the reducer is connected to a ball screw through a coupling.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By rotating the rotating rod, the rotating ring will drive the pulley to roll inside the carriage. The push rod fixed at the front end of the carriage will move synchronously with the carriage. By utilizing the sliding cooperation between the pulley and the carriage, the rotational motion is converted into linear motion of the push rod under the action of the limiting ring, avoiding deviation. When the push rod pushes the push plate, the push plate will slide along the guide trajectory of the limiting block, eventually driving the first longitudinal clamping plate at the front end of the support rod to move closer to the second longitudinal clamping plate fixed on the second mounting plate, forming a stable longitudinal clamping, ensuring that the back plate is firmly fixed in the longitudinal direction, and avoiding the impact of longitudinal displacement on accuracy during processing. 2. When the push plate pushes the support rod to move the first longitudinal clamping plate to the second longitudinal clamping plate, the spring will compress or rebound in real time according to the actual situation of the back plate. When facing a thin plastic back plate, the reaction force of the back plate on the clamping plate is small, the spring compression is small, and the clamping force is gentle, avoiding damage to the back plate due to excessive force. When facing a thick metal back plate, the reaction force of the back plate increases, the spring compression increases accordingly, and the clamping force increases synchronously, ensuring that the back plate will not loosen.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a back panel processing device for a display, including a base 1, a worktable 2 fixedly installed on the upper end of the base 1, a rotating rod 3 fixedly connected through both ends of the worktable 2, a rotating ring 4 sleeved on the outer ring of the rotating rod 3, a pulley 5 fixedly installed at the front end of the rotating ring 4, a slide 6 sleeved on the outer ring of the pulley 5, a push rod 7 fixedly installed at the front end of the slide 6, a connecting ring 8 sleeved on the outer ring of the push rod 7, a limiting ring 9 sleeved on the outer ring of the push rod 7, a push plate 10 sleeved on the outer ring of the connecting ring 8, a limiting block 11 fixedly installed on the upper end of the base 1, a support rod 12 fixedly installed through both ends of the push plate 10, a fixing ring 13 fixedly installed at the rear end of the support rod 12, a spring 14 sleeved on the outer ring of the support rod 12, a first longitudinal clamping plate 15 fixedly installed at the front end of the support rod 12, a second mounting plate 22 fixedly installed on the upper end of the base 1, and a second longitudinal clamping plate 23 provided at the front end of the second mounting plate 22.

[0019] Furthermore, the lower end of the limiting ring 9 is fixedly connected to the base 1, and the push plate 10 and the first longitudinal clamping plate 15 are connected by the spring 14. With the setting of the spring 14, the two ends of the spring 14 respectively abut against the push plate 10 and the fixing ring 13, and the clamping force can be adaptive through elastic buffering. When facing the thin plastic back plate, the force is gentle and avoids crushing and deformation.

[0020] Furthermore, a guide rail 16 is fixedly installed at the lower end of the worktable 2, and a slider 17 is fixedly installed at the upper end of the guide rail 16. Both ends of the slider 17 are connected by ball screws 18. The guide rail 16 provides a rigid guide rail for the slider 17, so that the slider 17 can only move stably along a straight track under the drive of the ball screws 18, thus avoiding the decrease in the alignment accuracy of the first horizontal clamping plate 21 and the second horizontal clamping plate 25 due to path deviation during lateral clamping adjustment.

[0021] Furthermore, a connecting block 19 is fixedly installed on the upper end of the slider 17, a slide groove is provided on the upper end of the worktable 2, a first mounting plate 20 is fixedly installed on the upper end of the connecting block 19, and a first transverse clamping plate 21 is provided at the front end of the first mounting plate 20. Through the setting of the connecting block 19, the connecting block 19 passes through the slide groove at the upper end of the worktable 2 and slides along the slide groove, so that the transverse clamping plate moves laterally along the guide rail 16.

[0022] Furthermore, a third mounting plate 24 is fixedly installed on the upper end of the workbench 2, and a second transverse clamping plate 25 is provided at the front end of the third mounting plate 24. Through the setting of the second transverse clamping plate 25, the fixing structure of the second transverse clamping plate 25 can also form a bidirectional clamping force with the first transverse clamping plate 21, ensuring that the back plate is evenly clamped in the transverse direction.

[0023] Furthermore, a mounting base 26 is fixedly installed on the upper end of the base 1, a processing arm 27 is fixedly installed on the upper end of the mounting base 26, and a processing fixture 28 is provided on the upper end of the mounting base 26. Through the setting of the processing arm 27, as the core processing execution component of the device, it can carry processing tools such as drilling, cutting, and grinding, and directly process the display back panel that has been limited in four directions by longitudinal and transverse clamps.

[0024] Furthermore, a drive motor 29 is provided at the upper end of the base 1. The output end of the drive motor 29 is connected to a belt via a synchronous pulley. The belt is connected to a reducer 30 via another set of synchronous pulleys. The output end of the reducer 30 is connected to the ball screw 18 via a coupling. The reducer 30 is model NMRV030. By reducing the output speed of the drive motor 29 and increasing the torque, the ball screw 18 is ensured to obtain a smooth and sufficient driving force.

[0025] Working Principle: The base 1 serves as the supporting foundation for the entire device. The back plate to be processed is placed on the surface of the worktable 2. Power is provided by the drive motor 29, which transmits power to the reducer 30 through the synchronous pulley and belt. After the reducer 30 reduces the speed and increases the torque, its output end drives the ball screw 18 to rotate through the coupling. The slider 17 moves laterally in a straight line along the guide rail 16 fixed at the lower end of the worktable 2, constrained by the guide rail 16 fixed at the lower end of the worktable 2. The connecting block 19 fixed at the upper end of the slider 17 moves synchronously through the slide groove at the upper end of the worktable 2, causing the first mounting plate 20 at the upper end of the connecting block 19 and the first transverse clamping plate 21 at the front end to move closer to the second transverse clamping plate 25 at the front end of the third mounting plate 24 fixed at the upper end of the worktable 2, thus completing the transverse clamping and fixing of the back plate. The rotating rod 3 fixed through both ends of the worktable 2 is driven to rotate, and the rotating ring 4 sleeved on its outer ring rotates synchronously with the rotating rod 3. The pulley fixed at the front end of the rotating ring 4 5 rolls within the slide 6. The push rod 7 fixed at the front end of the slide 6 moves with the slide 6. The limiting ring 9 on the outer ring of the push rod 7 constrains the push rod 7 to move in a straight line to prevent deviation. The push rod 7 drives the push plate 10 to move through the connecting ring 8 on the outer ring. The push plate 10 slides in a direction along the limiting block 11 fixed at the upper end of the base 1. The support rods 12 fixed at both ends move synchronously with the push plate 10. The spring 14 on the outer ring of the support rod 12 moves with the support rod 12. The first longitudinal clamping plate 15 at the front end moves closer to the second longitudinal clamping plate 23 at the front end of the second mounting plate 22 fixed at the upper end of the base 1. The elastic buffer of the spring 14 achieves longitudinal flexible clamping, which can adapt to back plates of different materials or thicknesses. After completing the four-way limiting in the horizontal and vertical directions, the processing arm 27 on the mounting base 26 fixed at the upper end of the base 1 carries the processing fastener 28 to perform drilling, cutting and other processing operations on the fixed back plate until the processing is completed.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
