Description

Technical Field

[0001] The present invention relates to the technical field of frameless TV backplane assembly, and specifically to a profiling tooling plate for supporting the frameless TV backplane. Background Art

[0002] During the manufacturing or installation process of frameless TVs (such as OLED ultra-thin models), due to the structural properties of the frameless TV backplane products, the deformation strength of the backplane and the assembly accuracy of the screen gap during module assembly cannot meet the process requirements, resulting in the inability to smoothly carry out the order production of this series of products;

[0003] This requires the use of a profiling tooling plate for the frameless TV backplane. The profiling tooling plate is a key auxiliary tool for supporting, positioning, and protecting the screen backplane, and needs to balance good adaptability, scratch resistance, and lightweight requirements.

[0004] The utility model patent with the patent authorization announcement number CN215358259U discloses a rapid assembly tooling for a TV backplane and fitting parts, including a bottom plate. The bottom plate is provided with a plurality of first limiting parts and second limiting parts; the first limiting parts are provided with limiting grooves for placing the fitting parts and limiting the fitting parts; a backplane limiting area for positioning the backplane is formed between the plurality of second limiting parts, and the first limiting parts are located within the backplane limiting area.

[0005] However, the existing profiling tooling plate for supporting the frameless TV backplane also has certain deficiencies. First of all, although the existing profiling tooling plate for supporting the frameless TV backplane uses plate parts, fitting parts, etc. to support and position the frameless TV backplane, due to the influence of factors such as the specifications and sizes of the frameless TV backplane, it is difficult for operators to perform modular rapid positioning processing on the frameless TV backplane;

[0006] Secondly, the existing profiling tooling plate for supporting the frameless TV backplane mostly simply uses elastic materials such as thick silicone pads to release pressure and buffer the frameless TV backplane. Due to the limitations of the elastic material itself, the buffering effect will become weaker after long-term use, and the fixed structure design of the profiling tooling plate makes it difficult to finely adjust and deflect the frameless TV backplane, resulting in poor assembly efficiency of the frameless TV backplane in the follow-up. Summary of the Invention

[0007] The purpose of the present invention is to provide a profiling tooling plate for supporting the frameless TV backplane to solve the above problems and address the issues mentioned in the background art.

[0033] Among them, an auxiliary mechanism 9 is jointly provided on the support shaft 3, the support frame 2 and the base 1. The auxiliary mechanism 9 includes a first spring 91. The first spring 91 is arranged outside the support shaft 3. One end of the first spring 91 is welded to the base 1, and the other end of the first spring 91 is welded to the tooling plate body 4. A damping hole 92 is formed in the side surface of the support shaft 3. There are a plurality of damping holes 92, and the plurality of damping holes 92 are evenly distributed on the support shaft 3. Through the setting of the damping holes 92, it is convenient to cooperate with the damping balls 96 to wear the excessive deformation stress generated by the first spring 91.

A small gear 992 is fixedly sleeved outside the output shaft of the servo motor 991. The small gear 992 meshes with the large gear 990. Two evenly distributed fixing ears 993 are fixedly connected to the horizontal part of the support frame 2. An elastic sleeve 994 is bonded to one end surface of the fixing ear 993 close to the rotating shaft 98. The other end of the elastic sleeve 994 is bonded with a connecting frame 995. A limiting block 996 is fixedly connected to the horizontal rod of the connecting frame 995. The limiting block 996 contacts the rotating shaft 98. A reinforcing rib 997 is welded to the end surface of the fixing ear 993 away from the rotating shaft 98. The short right-angled side of the reinforcing rib 997 is welded to the horizontal part of the support frame 2. Through the setting of the reinforcing rib 997, the fixing ear 993 can be reinforced. Through the action of structures such as the servo motor 991 and the large gear 990, the rotating shaft 98 can be driven to rotate, so that the base 1 rotates, and then drives the tooling plate body 4 to deflect, and the position of the back panel of the borderless TV is finely adjusted to improve the subsequent assembly efficiency.

[0035] Among them, a lubrication mechanism 10 is provided on the mounting ear 5. The lubrication mechanism 10 includes a lubricating sleeve 101. The end face of the mounting ear 5 close to one side of the tooling plate body 4 is fixedly connected with the lubricating sleeve 101. The lubricating sleeve 101 is slidably connected with the telescopic end of the synchronous cylinder 6. The upper end of the mounting ear 5 is fixedly connected with a mounting box 102. The inner wall of the mounting box 102 is fixedly connected with a circulation pipe 103. The circulation pipe 103 is fixedly connected with the lubricating sleeve 101. A plug 104 is slidably connected to the inner wall of the mounting box 102. The plug 104 is in contact with the circulation pipe 103. A third spring 105 is fixedly connected to the horizontal part of the plug 104. The other end of the third spring 105 is welded to the mounting box 102. An extension line 106 is fixedly connected to the upper end of the plug 104. The extension line 106 is slidably connected with the mounting box 102. A handle 107 is in contact with the end face of the mounting box 102. The handle 107 is fixedly connected with the extension line 106. Through the setting of the handle 107, it is convenient to pull the extension line 106 for moving use. A support piece 108 is fixedly connected to the inner bottom of the mounting box 102. A guide post 109 is fixedly connected to the horizontal part of the support piece 108. The guide post 109 is in contact with the extension line 106. Through the setting of the guide post 109, the extension line 106 can be guided for use. By driving the plug 104 to move through the extension line 106, the third spring 105 is deformed, so that the mounting box 102 is in a flowing state. And with the cooperation of the circulation pipe 103, the lubricating oil can be guided, and finally the synchronous cylinder 6 can be lubricated for use.

[0036] The specific implementation process of the present invention is as follows: During use, by contacting and fitting the frameless TV backplane with the tooling plate body 4, under the extrusion of force, the tooling plate body 4 moves downward to drive the support shaft 3 to slide along the inner wall of the base 1, so that the first spring 91 is deformed to buffer the frameless TV backplane. And when the support shaft 3 moves, under the extrusion of the inner wall of the damping hole 92, the damping ball 96 can be pushed to move, so as to drive the connecting rod 95 to move, and then drive the sliding plate 94 to slide along the surface of the sliding rod 93, so that the second spring 97 is deformed. Finally, the damping ball 96 disengages from the damping hole 92. Under the action of force, the damping ball 96 slides along the surface of the support shaft 3. When the damping ball 96 slides into the next damping hole 92, the second spring 97 recovers its deformation to push the sliding plate 94 to drive the connecting rod 95 to move in the direction close to the support shaft 3, so as to drive the damping ball 96 to insert into the next damping hole 92 on the surface of the next support shaft 3. This process repeats. With the cooperation of structures such as the damping ball 96 and the damping hole 92, the redundant deformation stress generated by the first spring 91 can be worn out, avoiding the problem of excessive jitter of the first spring 91;

[0037] The telescopic end is driven to move by the synchronous cylinder 6, so as to drive the positioning clip 7 to slide along the surface of the tooling plate body 4, modularly adjust the position of the positioning clip 7, and then quickly position and clamp the backplane of the frameless TV for use, so as to ensure the stable fitting of the backplane of the frameless TV. The handle 107 can be pulled to move away from the mounting box 102, so as to drive the traction wire 106 to move, make the traction wire 106 slide along the surface of the guide post 109. Under the action of the guide post 109, the movement of the traction wire 106 can be ensured to be stable, and then the plug 104 is pulled upward, causing the third spring 105 to deform, and finally the plug 104 is separated from the mounting box 102. Under the action of the flow pipe 103, the lubricating oil can be conducted, so that the lubricating oil contacts the lubricating sleeve 101, and the lubricating sleeve 101 is made of polypropylene fiber material, with good hydrophobic and lipophilic properties. Finally, the lubricating oil contacts the telescopic end of the synchronous cylinder 6 to lubricate the synchronous cylinder 6 and reduce the telescopic resistance of the synchronous cylinder 6;

[0038] The output shaft is driven to rotate by the servo motor 991, so as to drive the small gear 992 to rotate. In the meshing relationship, the small gear 992 drives the large gear 990 to rotate, so as to drive the rotating shaft 98 to rotate, and then drive the limit disc 99 to rotate along the horizontal part of the support frame 2. Under the action of the limit disc 99, the rotation of the rotating shaft 98 can be guided to ensure the rotation stability of the rotating shaft 98. When the rotating shaft 98 rotates, the base 1 can be driven to deflect, so that the support frame 2 gradually deviates from the base 1, and the support shaft 3 is driven to rotate. Under the guiding action of the two support shafts 3, the tooling plate body 4 can be driven to rotate, and the position of the backplane of the frameless TV can be deflected and finely adjusted for use, so as to improve the subsequent modular assembly efficiency;

[0039] When the rotating shaft 98 rotates, the limit block 996 can slide along the surface of the rotating shaft 98. Under the action of the limit block 996, the rotation of the rotating shaft 98 can be guided for use to ensure the good stability of the rotating shaft 98. Under the deformation action of the elastic sleeve 994, the connecting frame 995 can be pushed to move, so as to drive the limit block 996 to always contact the rotating shaft 98, to ensure the good fitting and limiting effect of the limit block 996, and then ensure the rotation stability of components such as the rotating shaft 98 and the base 1.
