Description

Technical Field

[0001] The utility model relates to the technical field of film adsorption equipment, in particular to an integrated device specially used for vacuum machine film adsorption, telescopic and shaking materials. Background Art

[0002] The vacuum machine is a process manufacturing equipment for producing automobile leather instrument cases. The production process of the vacuum machine is mainly composed of the following important components: the film adsorption device is used to adsorb the film raw materials placed in the box. The film is taken out through the adsorption device and fixed on the film frame. The film frame fixes the film and sends it into the heating furnace for high-temperature baking until the glue on the bottom layer of the film melts. Then the film is pressed onto the instrument case through the mold on the press, so that the film is completely attached to the surface of the instrument case.

[0003] However, the existing film adsorption device cannot adsorb film raw materials of different thicknesses under the same conditions. Since the same number of two different specifications of film raw materials stacked in a box have different thicknesses, after the film adsorption device finishes adsorbing the first type of film raw material, when it adsorbs the other type of film raw material, it is necessary to adjust the descending height of the film adsorption device, which wastes a lot of time.

[0004] The applicant has found that the prior art has at least the following technical problems:

[0005] In the prior art, the film adsorption device cannot automatically adjust the adsorption height, so as to directly adsorb film materials of different thicknesses. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0031] The utility model provides an integrated device for vacuum machine film adsorption, telescopic and shaking materials, including a cylinder assembly 1, a suction cup assembly 2, a body bracket 3 and an elastic assembly 4, wherein the piston rod of the cylinder assembly 1 is connected to the suction cup assembly 2, the cylinder assembly 1 is slidably connected to the elastic assembly 4, the body bracket 3 is connected to the elastic assembly 4, and the body bracket 3 is connected to the servo motor on the vacuum machine. The utility model provides an integrated device for vacuum machine film adsorption, telescopic and shaking materials. When the device is adsorbing, the servo motor will drive the device as a whole to move toward the film material to be adsorbed according to the previous operating rules. When the suction cup assembly 2 squeezes the film material, the squeezing force will push the suction cup assembly 2 in the opposite direction, thereby transmitting to the elastic assembly 4, and the elastic assembly 4 will be compressed, so that the suction cup assembly 2 will rise. At the same time, the cylinder assembly 1 will also control the suction cup assembly 2 to do telescopic movement, so as to automatically adjust the distance between the suction cup assembly 2 and the film material for adsorption, thereby solving the technical problem that the film adsorption device in the prior art cannot automatically adjust the adsorption height.

[0032] As an optional implementation, the elastic component 4 includes a linear guide rail 41, a slider bracket 42 and a spring structure 43. The linear guide rail 41 is connected to the main body bracket 3, the slider bracket 42 is connected to the cylinder assembly 1, the linear guide rail 41 and the slider bracket 42 are slidably connected, and the two ends of the spring structure 43 are respectively connected to the main body bracket 3 and the main body bracket 3. When the cylinder assembly 1 is subjected to extrusion force, it will push the slider bracket 42 to move relative to the linear guide rail 41, so that the spring structure 43 will be compressed.

[0033] As an optional embodiment, the slider bracket 42 includes a sliding block 421 and a U-shaped frame 422, the sliding block 421 is connected to the side end of the U-shaped frame 422, and the sliding block 421 is slidably connected to the linear guide rail 41;

[0034] A first through hole is provided at the lower end of the U-shaped frame 422, and the first through hole is connected to the shell of the cylinder assembly 1. An avoidance groove and a second through hole are provided at the upper end of the U-shaped frame 422. The cylinder assembly 1 passes through the avoidance groove, and the spring structure 43 is connected to the second through hole. There are two second through holes, and the two second through holes are respectively located on both sides of the avoidance groove. There are two spring structures 43.

[0035] As an optional embodiment, the spring structure 43 includes a guide rod 431, a spring 432, a motion block 433 and a nut 434. One end of the guide rod 431 passes through the upper plate of the body bracket 3 and is connected to the nut 434. There are nuts 434 on both sides of the upper plate. The upper end of the guide rod 431 is fixed to the upper plate of the body bracket 3 by two nuts 434. The motion block 433 and the spring 432 are both sleeved on the guide rod 431 and the motion block 433 is slidably connected to the guide rod 431. The motion block 433 is connected to the slider bracket 42. The other end of the guide rod 431 passes through the slider bracket 42 and is connected to the nut 434. The nut is to prevent the slider bracket 42, the motion block 433 and the spring 432 from detaching from the guide rod 431. The spring 432 is located between the motion block 433 and the upper plate. When the cylinder assembly 1 is subjected to the extrusion force, it will push the slider bracket 42 to move relative to the linear guide rail 41, thereby driving the motion block 433 to move upward, thereby compressing the spring 432.

[0036] As an optional implementation, it also includes an overpressure sensor 5 and a jitter sensor. The overpressure sensor 5 is installed on the upper plate of the main body bracket 3. There is a safety distance between the lower end of the overpressure sensor 5 and the upper end of the U-shaped frame 422. The overpressure sensor 5 is used to protect the overpressure function between the membrane material and the suction cup assembly 2. When the actual amount of membrane material is greater than the equipment detection amount, it will cause the servo to descend too much, the slider bracket 42 to move too high, and reach the safety distance, which will be sensed by the overpressure sensor 5. The overpressure sensor 5 will send an overpressure alarm message, and then the vacuum machine will stop the servo and continue to descend. At the same time, the alarm message reminds the operator that the actual amount of membrane material is inconsistent with the equipment input amount. The jitter sensor will be used to sense the number of times the cylinder assembly 1 is extended and retracted, so as to determine that the cylinder assembly 1 will perform a jitter operation to prevent two membrane materials from being adsorbed by the suction cup assembly at the same time, thereby causing the excess membrane material to fall.

[0037] As an optional implementation, the air inlet on the cylinder assembly 1 and the air vent on the suction cup assembly 2 are both connected to the air pump on the vacuum machine, a first solenoid valve is arranged between the air inlet and the air pump, and a second solenoid valve is arranged between the air vent and the air pump.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
