Description

Technical Field

[0001] The utility model belongs to the technical field of equipment with a lifting structure at the bottom of a table, and particularly relates to a device for improving a top pin structure. Background Art

[0002] Currently, the market demand for LCD glass panels is increasing, and the requirements for the development efficiency of LCD glass panel production lines are also becoming increasingly higher. With the increasing attention paid to production space, production efficiency and production processes, the requirements for the automation efficiency of existing equipment are becoming increasingly higher.

[0003] Existing liquid crystal glass panels are usually transported in two ways: one is to use a roller clamping mechanism to directly clamp the substrate for transportation; the other is to first use the top PIN on the positioning mechanism to blow up the substrate and then clamp it with a clamping mechanism.

[0004] However, most existing top PIN structures have a hole in the table top, and the bottom top PIN is raised and lowered through the hole. If the top PIN hole is too large, it will affect the uniformity of the table top temperature. If the top PIN hole is too small, there will be a slight deviation at the top, and it will scratch the table top during lifting and lowering, generating dust. The dust will fall on the product, affecting the product quality. At the same time, long-term scratching will put stress on the top pin base structure, causing deformation and damage. Therefore, this solution proposes a device to improve the top pin structure. Utility Model Content

[0005] 1. Technical problems to be solved:

[0006] In response to the problems existing in the prior art, the purpose of the present utility model is to provide an improved top pin structure device. By changing the top pin structure with an opening in the table top into a C-shaped structure, the pin is wrapped around the periphery of the table top, thereby solving the quality risk caused by scratching the table top and generating dust during lifting.

[0007] 2. Technical solution:

[0008] In order to solve the above problems, the present invention adopts the following technical solutions.

[0009] A device for improving the top pin structure comprises a machine frame, wherein the upper ends of both sides of the machine frame are fixedly connected with connecting rods, the upper ends of the connecting rods are fixedly connected with a connecting platform, a top pin lifting plate is provided between the inner walls of the connecting rods, a cylinder is installed between the top pin lifting plate and the top of the machine frame, sliding sleeves are respectively embedded and installed at the four diagonal positions of the upper end of the connecting platform, a bracket is movably connected between the inner walls of the sliding sleeves, the lower end of the bracket is fixedly connected to the top pin lifting plate, the upper end of the bracket is installed with a C-shaped top pin assembly, the upper end of the connecting platform is fixedly connected with a baking table, and the baking table is located between the inner walls of multiple C-shaped top pin assemblies.

[0010] A further improvement is that the C-shaped top pin assembly includes a C-shaped top pin, the upper end of the C-shaped top pin is provided with a plurality of evenly distributed top pin threaded holes, the edge end of the bottom side of the C-shaped top pin is provided with a through hole, the through hole is located on the outside of the bracket, and the upper side of the through hole is provided with a nut that engages with the threaded end of the top side of the bracket.

[0011] 3. Beneficial effects:

[0012] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0013] The utility model has a reasonable design. On the original lifting structure, the pin in the hole is eliminated and the top pin is made into a C shape in a bending form and wrapped around the periphery of the table. When the top pin base is raised or lowered, the C-shaped pin structure does not contact the table, thereby solving the problem of friction and dust. The overall use cost is lower, the structure is simple, and the production is easier.

[0014] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and are the same as the existing technology or can be implemented by using the existing technology, so they are not described in detail here.

[0019] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0022] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0023] See also Figure 1-2 , a device for improving the top pin structure, including a machine frame 1, the upper ends of both sides of the machine frame 1 are fixedly connected with a connecting rod 2, the upper end of the connecting rod 2 is fixedly connected with a connecting platform 3, a top pin lifting plate 4 is provided between the inner walls of the connecting rod 2, a cylinder 5 is installed between the top pin lifting plate 4 and the top of the machine frame 1, a sliding sleeve 6 is respectively embedded and installed at the four diagonal places on the upper end of the connecting platform 3, a bracket 7 is movably connected between the inner walls of the sliding sleeve 6, the lower end of the bracket 7 is fixedly connected to the top pin lifting plate 4, the upper end of the bracket 7 is installed with a C-shaped top pin assembly 8, the upper end of the connecting platform 3 is fixedly connected with a baking table 9, and the baking table 9 is located between the inner walls of multiple C-shaped top pin assemblies 8.

[0024] More specifically: the C-shaped top Pin assembly 8 includes a C-shaped top Pin 81, the upper end of the C-shaped top Pin 81 is provided with a plurality of evenly distributed top Pin threaded holes 82, the edge end of the bottom side of the C-shaped top Pin 81 is provided with a through hole 83, the through hole 83 is located on the outside of the bracket 7, and the upper side of the through hole 83 is provided with a nut 84 that engages with the threaded end of the top side of the bracket 7.

[0025] In this embodiment, the pin in the hole is eliminated from the original lifting structure. Instead, the top pin is made into a C-shape by bending it around the periphery of the table.

Compared with the existing technology, its overall use cost is lower, the structure is simpler, and it is easier to manufacture.
