[0002] The manufacturing process of LCD panels mainly includes the following core steps: TFT manufacturing, color filter manufacturing, coalescence / unit / liquid crystal injection, and module process, which together constitute the manufacturing process of LCD panels and ensure the quality and performance of the final product. First of all, TFT manufacturing is the basis of LCD panel manufacturing. The manufacture of TFT (thin film transistor) involves forming a conductive part on a glass substrate, usually using ITO (transparent conductive metal oxide) to control the movement of liquid crystal. This step includes forming a gate, an insulating layer, and a source / drain on the glass substrate, which is completed by techniques such as photolithography and etching. Next is color filter manufacturing. During the color filter manufacturing process, the color filter is made and fixed on the glass substrate to prepare for the subsequent liquid crystal injection. Coalescence / unit / liquid crystal injection is one of the key steps in the manufacture of LCD panels. The TFT glass and the color filter glass substrate are combined, and liquid crystal is injected between the two. Finally, the module process includes combining the liquid crystal unit with components such as the drive circuit and the backlight system to complete the assembly of the entire LCD panel. During the production of liquid crystal panels, it is sometimes necessary to change the orientation of the product or to rotate it. In the prior art, the rotary control console is not convenient for placing and taking out the product, and the production line occupies a large space, so it is necessary to make improvements. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] A turntable for producing liquid crystal panels, such as Figures 1 to 3As shown, it includes a base 2 with a turntable 1 installed, an outer protective shell 3 is provided on the periphery of the base, and an operation port 5 is opened on the front guard plate 4 of the outer protective shell, and a material unloading rack 6 is provided corresponding to the operation port, and the top of the outer protective shell is in an open state; the turntable is installed on the base through a lifting mechanism, and at the same time, a slide rail assembly is provided on the base corresponding to the turntable, and a material moving rack 7 is installed on the slide rail; the material moving rack is an overall U-shaped structure, including left and right material racks 9 and a reinforcement frame 10 between the two material racks, and a number of pulleys 11 are provided on the two material racks, each of which has the same height, and there is a gap between the pulley and the turntable. When the material moving rack moves, the pulley and the side material rack will not interfere with the turntable. The material unloading rack includes two left-right symmetrical frames 12, and the upper end of each frame is provided with a horizontal sliding surface 13 and an inclined discharge surface 14.

[0026] In an optional embodiment, the sliding surface of the frame is flush with the lower end surface of the operation port, and the highest point of the discharge surface is higher than the slide rail assembly. During the unloading process, the material moving frame moves outward, and when the reinforcing frame contacts the discharge surface, the discharge surface will limit the material moving frame. Usually, the discharge surface has an inclination angle of 5-10 degrees. When the material moving frame moves outward, the discharge surface will limit the material moving frame. When the reinforcing frame is close to the highest point of the discharge surface, its overall maximum tilt state (inclination angle of 5-10 degrees) can not only facilitate unloading, but also effectively prevent the material moving frame from falling off.

[0027] In order to improve the strength of the front guard plate, in an optional embodiment, H-shaped reinforcement frames 20 are symmetrically provided on both sides of the front guard plate corresponding to the operating port, and the two reinforcement frames are connected by a cross beam to strengthen the structural strength of the front guard plate, thereby ensuring that the force on the material moving rack is stable when moving and it is not easy to deform during long-term use.

[0028] The slide rail assembly includes rails 8 symmetrically arranged on both sides of the turntable. The material racks on both sides of the material transfer rack are respectively located on both sides of the turntable, and each side material rack is slidably mounted on the corresponding rails. In an optional embodiment, the base includes a table top and a box under the table top, and the table top is provided with a plurality of hollow holes, each of which is connected to the inner cavity of the box. The scraps or liquids produced by processing will flow into the box through the hollow holes, and the box can be cleaned regularly.

[0029] Usually, the pulleys on the racks on both sides are of the same size. The rack body includes a top rack portion 21 and a bottom rack portion 22, and a plurality of support portions 23 are provided between the top rack portion and the bottom rack portion. The lifting mechanism includes a lifting cylinder installed in the box body, the extension rod end of the lifting cylinder is arranged upward, and the turntable is installed at the top of the extension rod. Each pulley is a rubber wheel or a nylon wheel.

[0030] In an optional embodiment, if Figure 4 and Figure 5As shown, an anti-return mechanism 15 is symmetrically arranged on the left and right side walls of the protective shell. Specifically, the anti-return mechanism includes an anti-return bar 16 arranged on the side panel. The anti-return bar is arranged obliquely downward, and a stop bar 17 is hinged at its end. A tension spring 18 is provided between the stop bar and the anti-return bar, and an anti-rotation part 19 is provided on the upper side of the anti-return bar. Under normal circumstances, the tension spring can pull up the stop bar and make the lower end of the anti-rotation part press against the stop bar to prevent the stop bar from flipping upward. Such a structural design allows the edge of the product to touch the stop bar and drive the stop bar to flip downward when feeding, while preventing the product from moving in the opposite direction, which can effectively prevent the feeding robot from taking the product out of the top of the protective shell and causing a production accident.

[0031] The invention has a reasonable structural design. The robot arm grabs the product to be processed and enters through the opening at the top of the protective shell and places it on the turntable. The rotation of the turntable is then used to adjust the product orientation for processing. After the processing is completed, the lifting mechanism falls, causing the turntable to move down until the product falls onto the material transfer rack. The material transfer rack is then moved to move the product to the material unloading rack, and finally the product is transported away manually or by a robot. The production operation is simple and is conducive to realizing automated production. At the same time, the robot can be arranged on the front and rear sides of the turntable to save floor space.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
