Description

Detection table

Technical Field

The invention relates to the technical field of electronic product detection, in particular to a detection table.

Background

Various substrates, such as liquid crystal panels, OLED (Organic Light-Emitting Display) panels, touch panels, glass substrates, etc., need to be placed on a detection table to detect whether defects exist in the substrates during production or before leaving a factory, and a general detection table can only bear panels of one size. For example, when a liquid crystal display panel is manufactured, liquid crystal is filled between upper and lower substrates, and frame glue is applied to the edges of the substrates in order to seal the liquid crystal between the upper and lower substrates. Because the machine stability of the glue coating mechanism and the possible situations of glue overflow, blockage, bubbles and the like exist at the glue outlet head, in order to ensure the sealing performance between the upper substrate and the lower substrate, the coated glue needs to be uniform and qualified in size, and therefore the substrate after being coated with the glue needs to be placed on a detection table to detect whether the size of the glue is qualified or not. The detection table in the prior art only corresponds to the base plate of one specification, the base plates of different specifications need to be replaced by different detection tables, and the detection table is low in universality, so that the detection efficiency is low.

At least one group of bearing components 2 positioned at two ends are movably connected to the working support 1, when the adjacent bearing components 2 are close to each other, the size of the first carrying platform along the first direction can be reduced, and therefore a piece to be tested with a smaller size can be borne; when the adjacent bearing assemblies 2 are far away, the size of the first carrying platform along the first direction can be increased, so that the piece to be tested with larger size can be carried. The detection table can adapt to various pieces to be detected with different sizes, the detection table in the detection equipment does not need to be frequently replaced, and the universality and the working efficiency of the detection table are improved.

As shown in fig. 2 and 3, the detection table further includes a driving assembly 3, and the carrying assembly 2 is drivingly connected to the working support 1 to drive the carrying assembly 2 to move.

Specifically, the driving assembly 3 includes a driving member 31, a first synchronous pulley 32, a second synchronous pulley 33, a synchronous belt 35 and a screw assembly, wherein the screw assembly includes a positive and negative screw 34 and a nut 36 in the present embodiment.

The first timing pulley 32 is drivingly connected to the output of the drive member 31, and the second timing pulley 33 is drivingly connected to the first timing pulley 32 via a timing belt 35. The positive and negative screw rods 34 are connected with the second synchronous belt pulley 33 in a transmission way and are connected with the working bracket 1 in a rotating way. The nut 36 is screwed on the positive and negative screw rods 34, and the movable bearing component 2 is fixedly connected with the nut 36; of course, in other embodiments, the driving member 31 can also directly drive the positive and negative lead screws 34 to achieve the purpose of driving the carrying assembly 2; however, the present invention is not limited to this, and the bearing assemblies 2 at the two ends may also be driven synchronously or asynchronously by different driving mechanisms, so as to adjust the positions of the bearing assemblies 2.

In order to improve the stability of the carrying assembly 2 during movement, a guide rail 4 may be further disposed on one of the working bracket 1 and the carrying assembly 2, wherein a sliding groove is disposed on the other one of the working bracket 1 and the carrying assembly 2, and the sliding groove is slidably connected to the guide rail 4, so that the carrying assembly 2 can stably and straightly slide on the working bracket 1.
