Description

Technical Field

[0001] This utility model relates to the field of display screen manufacturing technology, specifically to a workbench for display screen manufacturing. Background Technology

[0002] The display screen production workbench is a specialized device in the field of display screen manufacturing equipment. It consists of a workbench base, an operating table, etc. The top operating table has a placement slot and a built-in fixing device with springs and anti-slip layers to stabilize the display screen and prevent damage. The side adjustment devices can flexibly adjust the height and tilt angle of the operating table to adapt to different display screen sizes and operational needs. The rotating structure at the bottom can control the rotation of the placement table to adjust the processing position. It is equipped with a tool cabinet with dividers and drawers to classify and store tools and parts, solving the problems of inconvenient adjustment, insufficient fixing and protection, and messy storage of traditional workbenches, thereby improving production efficiency and safety.

[0003] However, the rotating structure at the bottom of the worktable used in display production usually consists of a motor and a connecting shaft. During the processing, fluctuations in the motor's power output, deviations in the coaxiality of the connecting shaft, and coupling of inertial forces of the rotating parts can easily cause vibrations in the rotating structure. These vibrations can be transmitted to the worktable, affecting the processing, leading to decreased processing accuracy, quality defects, accelerated wear of components, and reduced equipment lifespan. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a workbench for display screen production, which can effectively solve the problem that the placement table shakes due to processing vibration during the processing, thus leading to processing failure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a workbench for display screen production, including a base, and a placement platform for placing the display screen is provided on the top of the base. The placement platform is rotated by a rotating component.

[0007] The rotating assembly includes a rotating shaft fixedly connected to the bottom of the placement platform, and the rotating shaft is disposed in the mounting groove.

[0008] A friction assembly is provided inside the rotating shaft. The friction assembly includes a friction contact plate disposed inside the rotating shaft. One side of the friction contact plate abuts against the mounting groove, and the other side of the friction contact plate is connected to a friction wedge plate via a friction pressure spring.

[0009] According to the above-mentioned workbench for producing a display screen, the mounting slot is formed in the base, a rotary motor is installed in the mounting slot, the rotary motor is used to drive the rotating shaft to rotate, a positioning ring is fixedly connected to the side wall of the rotating shaft, the positioning ring is rotatably connected in the positioning slot, and the positioning slot is formed in the base.

[0010] The bottom of the rotating shaft is provided with a drive groove and a track groove. The drive shaft is slidably connected in the drive groove, and the slider is slidably connected in the track groove. The slider is fixedly connected to the side wall of the drive shaft, and the top of the drive shaft abuts against a friction wedge.

[0011] A sliding groove is provided inside the rotating shaft, and a friction contact plate and a friction wedge plate are slidably connected inside the sliding groove.

[0012] A reset plate is fixedly connected to the bottom of the friction contact plate. The reset plate is slidably connected in the reset groove, which is opened in the rotating shaft. The reset groove and the reset plate are connected by a reset spring.

[0013] A reversing assembly is provided at the bottom of the drive shaft. The reversing assembly includes a reversing groove formed at the bottom of the drive shaft. A reversing shaft is rotatably connected in the reversing groove. The reversing shaft and the reversing groove are connected by a reversing torsion spring. The output end of the rotary motor is fixedly connected to the bottom of the reversing shaft.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] This invention utilizes a combination of a rotating component and a friction component. When the placement table does not need to rotate, a friction-pressurized spring or similar device is used to press a friction contact plate against the inner wall of the mounting groove, increasing friction, stabilizing the placement table, and absorbing processing vibrations. When rotation is required, the contact plate is released without affecting rotation, effectively solving the problem of processing failure caused by vibration and shaking of the placement table, and improving processing accuracy, equipment stability, and lifespan.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: Refer to Figures 1 to 4 A workbench for producing a display screen includes a base 1, and a placement platform 2 for placing the display screen is provided above the base 1. The placement platform 2 is rotated by a rotating component 3.

[0025] The rotating component 3 includes a rotating shaft 33 fixedly connected to the bottom of the placement platform 2, and the rotating shaft 33 is disposed in the mounting groove 31;

[0026] Mounting slot 31 is formed in base 1. A rotary motor 32 is installed in mounting slot 31. Rotary motor 32 is used to drive rotary shaft 33 to rotate. A positioning ring 39 is fixedly connected to the side wall of rotary shaft 33. The positioning ring 39 is rotatably connected in positioning slot 38. Positioning slot 38 is formed in base 1.

[0027] The bottom of the rotating shaft 33 is provided with a drive groove 34 and a track groove 36. The drive shaft 35 is slidably connected in the drive groove 34, and the slider 37 is slidably connected in the track groove 36. The slider 37 is fixedly connected to the side wall of the drive shaft 35, and the top of the drive shaft 35 abuts against a friction wedge plate 43.

[0028] A friction assembly 4 is provided inside the rotating shaft 33. The friction assembly 4 includes a friction contact plate 42 disposed inside the rotating shaft 33. One side of the friction contact plate 42 abuts against a mounting groove 31, and the other side of the friction contact plate 42 is connected to a friction wedge plate 43 via a friction pressure spring 44.

[0029] A groove 41 is provided inside the rotating shaft 33, and a friction contact plate 42 and a friction wedge plate 43 are slidably connected inside the groove 41.

[0030] A reset plate 46 is fixedly connected to the bottom of the friction contact plate 42. The reset plate 46 is slidably connected in the reset groove 45, which is opened in the rotating shaft 33. The reset groove 45 and the reset plate 46 are connected by a reset spring 47.

[0031] A reversing component 5 is provided at the bottom of the drive shaft 35. The reversing component 5 includes a reversing groove 51 opened at the bottom of the drive shaft 35. A reversing shaft 52 is rotatably connected in the reversing groove 51. The reversing shaft 52 and the reversing groove 51 are connected by a reversing torsion spring 53. The output end of the rotary motor 32 is fixedly connected to the bottom of the reversing shaft 52.

[0032] The friction assembly 4, through the cooperation of the friction contact plate 42, the friction pressure spring 44, and the friction wedge plate 43, allows the friction contact plate 42 to abut against the inner wall of the mounting groove 31 when the placement table 2 does not need to rotate. This increases the friction between the rotating shaft 33 and the mounting groove 31, stabilizes the rotating shaft 33, and prevents wobbling. At the same time, the elastic deformation of the spring absorbs the processing vibration energy, reducing the impact of vibration on the placement table 2. When the placement table 2 needs to rotate, the contact can be released, reducing friction without affecting rotation. This effectively solves the problem of processing failure caused by the shaking of the placement table 2 due to processing vibration in the prior art.

[0033] The working principle of this utility model is as follows: When the placement platform 2 does not need to rotate, the rotary motor 32 stops moving. Under the action of the reversing torsion spring 53, the drive shaft 35 always abuts against the friction wedge plate 43, driving the friction wedge plate 43 to slide outward in the slide groove 41. Since a friction pressure spring 44 is connected between the friction wedge plate 43 and the friction contact plate 42, and the other end of the friction contact plate 42 always abuts against the inner wall of the mounting groove 31, the friction pressure spring 44 is compressed and transmits elastic potential energy to the friction contact plate 42, so that the friction contact plate 42 applies pressure to the mounting groove 31. Through this pressure application method, the friction between the rotating shaft 33 and the mounting groove 31 can be increased, thereby ensuring the stability of the rotating shaft 33 and avoiding rotation.

[0034] When the placement platform 2 needs to rotate, the rotary motor 32 starts running, driving the reverse shaft 52 to rotate. At this time, the reverse torsion spring 53 is subjected to torque. When the reverse torsion spring 53 is twisted to its limit, the drive shaft 35 starts to rotate. At this time, since the track groove 36 and the slider 37 are provided between the drive shaft 35 and the rotating shaft 33, and the rotating shaft 33 will not have vertical displacement under the action of the positioning groove 38 and the positioning ring 39, the drive shaft 35 starts to slide downward and releases the contact with the friction wedge plate 43. At this time, the friction wedge plate 43 and the friction contact plate 42 begin to retract into the slide groove 41 under the action of the friction pressure spring 44 and the return spring 47, no longer applying pressure to the mounting groove 31, thereby ensuring the normal rotation of the rotating shaft 33.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
