Description

Technical Field

[0001] The utility model relates to the technical field of a rubber frame pressing fixture, in particular to a rubber frame pressing fixture for a drawer-type structured frameless machine. Background Art

[0002] The existing rubber frame pressing operation method is manual pressing. During pressing, after the tongue of the jig is inserted into the rubber frame, it is necessary to press and slide the jig by hand, apply force to the rubber frame, so that the double-sided tape on the rubber frame adheres to the folded edge plane of the back panel to fix the rubber frame. However, since it is a manual operation and the personnel will become tired after working for a long time, the applied force cannot be controlled, and it is impossible to ensure that the rubber frame and the back panel are fully bonded. In the actual production process, debonding of the rubber frame and the back panel often occurs, which is a serious functional defect. In addition, the existing rubber frame pressing jig is made of stainless steel, and the rubber frame is made of plastic. When the jig is used, there is sliding friction between the rubber frame and the rubber frame. The rubber frame is relatively soft and has poor wear resistance. The jig is made of hard material and the friction with the soft rubber frame is easy to fall off, causing foreign matter to be displayed on the screen. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a drawer-type structure frameless machine plastic frame pressing fixture.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A drawer-type structure frameless machine rubber frame pressing fixture comprises a structural body, a handle is provided at the upper end of the structural body, a row of lower pressing rubber wheels is rotatably connected to the lower end of the structural body, a row of side limit rubber wheels is rotatably connected to the upper side of the lower pressing rubber wheels, and the side limit rubber wheels and the lower pressing rubber wheels are vertically arranged; a cylinder is fixed to the middle part of the structural body, a connecting seat is fixed to the end of the push rod of the cylinder, and a row of upper pressing rubber wheels corresponding to the lower pressing rubber wheels are arranged on the connecting seat; the cylinder is connected to the switching valve through an air pipe, the switching valve is connected to the high-pressure air source through the air pipe, and the side of the switching valve is connected to a switching switch for controlling the action of the cylinder.

[0006] Furthermore, a digitally adjustable pressure gauge is connected to the air pipe between the switching valve and the high-pressure air source.

[0007] Furthermore, the digital adjustable pressure gauge is electrically connected to an alarm.

[0008] Furthermore, a guide rail arranged along the direction of the push rod is fixed on the cylinder body of the cylinder, and the guide rail is slidably connected to the connecting seat.

[0009] The utility model adopts the above technical solution, and has the following beneficial effects:

[0010] 1. The utility model uses the side limit rubber wheel for lateral limit, the upper and lower pressing rubber wheels cooperate with each other to press the rubber frame, and the cylinder produces a relatively stable and uniform pressing force, which can ensure the consistency of pressing and the bonding effect of the rubber frame and the back plate. When the air pressure exceeds the set range, the alarm will sound an alarm to effectively prevent major functional defects caused by the falling of the rubber frame and the adverse effects on brand quality;

[0011] 2. Change the sliding friction between the existing fixture and the plastic frame to rolling friction, which effectively reduces the residual foreign matter caused by the plastic frame chips falling off due to friction, reduces the disassembly and repair caused by screen display problems, and reduces the waste of labor and materials.
