Description

Turning machine for large television

Technical Field

The invention relates to the field of television production, in particular to a large television turning machine for turning over a large television on a first production line and standing on a second production line.

Background

With the continuous development of economy and the continuous progress of society, a very rich substance consumer product is provided for people, and a television is one of a plurality of substance consumer products.

In the production process of the large-sized television (namely 50 to 110 inches), the production process from the module assembly line to the test line of the large-sized television is not separated, and the mode of completing the process at present comprises a manual mode, a vacuum chuck vertical machine and a mechanical gantry vertical machine.

However, the manual mode is that the weight of the large-sized television reaches 110KG and the volume is heavy, so that the large-sized television is very difficult to carry and erect by personnel; the vacuum chuck vertical machine is used for enabling the mirror surface in the large-sized television without the frame to shift relative to the backboard due to the fact that the mirror surface of the large-sized motor is sucked in the process of overturning and vertically placing the large-sized television, so that the matching deviation between the mirror surface and the backboard is large, and the process requirement cannot be met; the mechanical gantry stand machine has higher occupied space and large area, and the maintenance part is convenient when in fault, so that the production takt cannot meet the requirement.

Accordingly, there is a strong need for a large television stand that overcomes one or more of the above-described drawbacks.

The working principle of the large television tilting machine of the invention is described with reference to the accompanying drawings:

on the first production line 210, after the mirror surface passes through the back plate, the front frame is clamped and screws are screwed into a standing machine process, and the large television 300 is carried in place by the tooling plate; after the centering mechanism 70 is in place, pushing the fourth side 340 of the large television 300 on the first production line 210, so that the large television 300 is in place, and the supporting mechanism 30 lifts up and supports the first side 310 of the large television 300, and the first clamping arm 40a and the second clamping arm 40b correspondingly clamp the second side 320 and the third side 330 of the large television 300 on the first production line 210 under the driving of the opening and closing driver 50; then, the turnover driver 60 pushes the turnover frame 20 to hold the large television 300 on the first production line 210 and separate the large television 300 from the tooling plate, and the tooling plate separated from the large television 300 flows away again; then, the held large television 300 falls onto the test fixture body of the second production line 220 after being turned 120 degrees under the driving of the turning driver 60 to the turning frame 20, and at this time, the first clamping arm 40a and the second clamping arm 40b release the clamping of the large television 300.

Compared with the prior art, with the coordination of the holding mechanism 30, the first clamping arm 40a, the second clamping arm 40b, the opening and closing driver 50, the turning driver 60 and the turning frame 20, the first side 310 of the large-sized television 300 on the first production line 210 is held by the holding mechanism 30 during the process of turning and standing the large-sized television 300 on the second production line 220, so that the second side 320 and the third side 330 of the large-sized television 300 on the first production line 210 are correspondingly held by the first clamping arm 40a and the second clamping arm 40b with the coordination of the opening and closing driver 50; then, the turnover driver 60 drives the turnover frame 20 to drive the clamped large television 300 to turn over and stand on the second production line 220; the first to third sides 330 of the large-sized television 300 are stabilized by adopting the holding mechanism 30, the first clamping arm 40a and the second clamping arm 40b, so the device is suitable for the overturning and standing operation of the large-sized television 300 with frames and without frames, and can effectively prevent the mirror surface in the large-sized television 300 from being displaced relative to the backboard to cause large deviation in the overturning and standing process, and avoid the mirror surface from being fragile by adopting a vacuum chuck; therefore, the large television tilting machine 100 of the invention can solve the problems that the mirror surface is fragile and the deviation between the mirror surface and the back plate is overlarge when the large television is tilted and raised, and has the advantages of small occupied space and convenient maintenance compared with a mechanical gantry frame.

Since the mirror surface of the large-sized tv 300 is glass, the pressing structure 424 and the pressing structure 423 of the first clamp arm 40a, the pressing structure 444 and the pressing structure 443 of the second clamp arm 40b, the supporting portion 331 and the side stopper 332 of the supporting block 33, the roller 85 of the back pushing mechanism 80, and the pushing structure 77 of the centering mechanism 70 are all provided with buffer structures made of flexible materials in order to prevent damage to the glass.

The foregoing disclosure is illustrative of the present invention and is not to be construed as limiting the scope of the invention, but is for the convenience of those skilled in the art to understand and practice the invention, and therefore, equivalent variations to the appended claims are intended to be encompassed by the present invention.
