Description

Technical Field

[0001] The utility model relates to the field of automobile glass production equipment, in particular to an automatic diaphragm trimming system. Background Art

[0002] Due to the requirements of relevant safety regulations and the requirements of different performances such as heat insulation and noise reduction, most of the glass on cars is a sandwich structure, that is, a layer of diaphragm with special properties is sandwiched between the inner and outer layers of glass. This diaphragm must extend a certain length outside the edge of the glass outline due to process requirements during the production process, and the finished glass requires that the diaphragm must not exceed the edge of the glass outline, so special equipment is needed to remove the diaphragm that exceeds the edge of the glass outline. The equipment currently available on the market, including our company's existing equipment for removing the edge of the diaphragm, adopts the principle of belt grinding, using a high-speed rotating annular grinding belt to grind the edge of the laminated glass. Because the hardness of the diaphragm is much lower than that of the glass and is easily worn away by the grinding belt, the edge of the diaphragm can be ground to be flush with the edge of the glass without basically damaging the glass, thus completing the production.

[0003] Although the existing belt-type diaphragm trimming equipment has the advantage of smooth edges of finished glass diaphragms, it also has some disadvantages. The high-speed rotation of the grinding belt makes a lot of noise, and grinding dust will inevitably appear during the grinding process. The production site environment is poor, and additional dust removal equipment is required. The products after grinding also require additional cleaning equipment for cleaning. In order to ensure the grinding effect, the production speed is slow, and it is difficult to significantly improve production efficiency. The grinding belt is grinding the glass while grinding the diaphragm. The finished glass edge has a frosted and rough surface. If the grinding belt grinds the diaphragm for a little longer, the glass edge will be polished and cause defects. At the same time, the grinding belt will also grind the hard glass edge, which results in a short life of the grinding belt. The grinding belt needs to be replaced frequently to ensure the grinding effect, which leads to increased costs.

[0004] In order to solve the shortcomings of existing grinding belt trimming equipment, our company has developed an automatic film trimming system, which integrates a film trimming robot, a conveyor, a blade feeding mechanism, etc. The system can use the blade clamped by the robot to cut off the film beyond the edge of the laminated glass to complete the production. The film is cut very quietly, does not produce grinding chips, is environmentally friendly, and only produces strip-shaped film waste, which is convenient for collection and cleaning. No additional dust removal equipment is required. The surface of the product after trimming is clean and no additional cleaning equipment is required; and the speed of the blade cutting the film is much higher than that of the grinding belt trimming equipment. Two blade trimming robots can also be equipped to cut the left and right edges of the same piece of glass at the same time, greatly improving production efficiency. Utility Model Content

[0020] In this embodiment, the lifting suction cup frame 103 is installed on the inner bottom of the belt conveyor body 101. After the correction wheel group 102 corrects the posture of the laminated glass, the lifting suction cup frame 103 can suck the glass through the suction cups arranged thereon and move forward and backward along the conveying direction.

[0021] In this embodiment, the support platform 2 is located at the rear side of the conveying direction of the positioning and moving conveyor 1, and the lifting suction cup frame 103 can be moved to the center position of the support platform 2. Adjustable lifting suction cups and support blocks are arranged on the support platform 2, and the glass is fixed based on the lifting suction cups.

[0022] In this embodiment, a trimming robot A3, a blade feeding mechanism A4, a trimming robot B5, and a blade feeding mechanism B6 are symmetrically installed on the left and right sides of the support table 2, wherein the trimming robot A3 grabs a new blade for diaphragm trimming from the blade feeding mechanism A4 and releases the old blade into the collection box of the blade feeding mechanism A4, and the trimming robot B5 grabs a new blade for diaphragm trimming from the blade feeding mechanism B6 and releases the old blade into the collection box of the blade feeding mechanism B6.

[0023] The working steps are as follows:

[0024] Step 1: The positioning and moving conveyor 1 inputs the laminated glass to be trimmed from the upstream conveying equipment. There are two motor-driven belts above the belt conveyor body 101 of the positioning and moving conveyor, which are responsible for inputting the glass into place. There are four front and rear correction wheels distributed along the conveying direction of the belt conveyor, and one correction wheel for left and right correction is distributed on each of the left and right sides of the belt conveyor. Two lifting horizontal support wheels are distributed along the two belts of the belt conveyor. The horizontal support wheels are responsible for lifting the glass off the belt surface of the belt conveyor for correction. The front and rear four correction wheels plus one correction wheel on the left and right, a total of six correction wheels, move from all sides to the edge of the glass to push the glass to correct the glass posture, so that the front and rear, left and right positions and angle postures of the glass can be kept consistent;

[0025] Step 2: The lifting suction cup frame 103 is lifted from the bottom and sucks the glass in the fixed position with a suction cup, then the six correction wheels used for positioning and the horizontal support wheels for lifting the glass are reset and separated from the glass, the lifting suction cup frame 103 sucks the positioned glass and moves it to the center of the support platform 2 to stop, and the suction cup of the lifting suction cup frame 103 descends to place the glass on the suction cup and support block of the support platform 2;

[0026] Step 3: The support platform 2 has an adjustable lifting suction cup and support block, which can effectively fix the positioned glass delivered by the lifting suction cup frame 103 to prevent movement and deformation; the suction cup and support block of the support platform 2 are lifted upward to lift the glass to a height that is convenient for trimming.

[0027] Step 4: After the suction cup and the support block of the support platform 2 fix the glass, the lifting suction cup frame 103 at the bottom of the positioning and moving conveyor 1 can break the vacuum to separate from the glass and return to the initial position at the bottom of the positioning and moving conveyor 1 to complete the reset;

[0028] Step 5: The trimming robot A3 grabs the blade for trimming the film from the blade feeding mechanism A4, and can also release the old blunt blade into the collection box of the blade feeding mechanism A4; the trimming robot B5 grabs the blade for trimming the film from the blade feeding mechanism B6, and can also release the old blunt blade into the collection box of the blade feeding mechanism B6; the trimming robots A3 and B5 perform actions according to the preset program, and at the same time drive the blade to move along the edge of the glass to cut off the excess film on the outer edge of the glass, that is, the two trimming robots are responsible for cutting off the film on the left and right sides of a piece of glass according to the preset program, which can shorten the production cycle;

[0029] Step 6: After trimming is completed, the robot resets and leaves the edge of the glass, and the moving conveyor 7 moves to the bottom of the support table 2. The suction cup and support block inside the support table 2 descend, and the trimmed glass is released onto the moving conveyor 7. The moving conveyor 7 resets and leaves the support table 2 along the conveying direction, and the glass continues to be output to the downstream equipment through the moving conveyor 7, completing the automatic trimming operation of the membrane.

[0030] It is worth noting that the entire device is controlled by a PLC control cabinet and a robot control cabinet. Since the equipment matched with the PLC control cabinet and the robot control cabinet is commonly used equipment and belongs to existing mature technologies, their electrical connection relationship and specific circuit structure will not be described in detail here.
