Referring to fig. 1 to 3, an automatic punching anti-loosening device for an automobile comprises a conveyor 10, a punching die 40, a robot 20 and an encoder 23, wherein the robot 20 is used for grabbing a conveyed automobile sealing strip product on the conveyor 10 and sending the conveyed automobile sealing strip product to the punching die 40 for punching, a clamping jaw 21 is installed at an execution end of the robot 20, and two clamping heads 22 are installed on the clamping jaw 21; the encoder 23 is used for detecting the Y-direction position of the automobile sealing strip product, and one encoder 23 is installed beside each chuck 22. The punching machine further comprises a control system for controlling the actions of the encoder 23, the robot 20 and the punching die 40. The punching die 40 is mounted on the punch 30.

An operator firstly installs an automobile sealing strip product on the conveyor 10, then confirms whether a PLC program in a control system is normal or not, presses down a start button, the automobile sealing strip product can run along the conveyor 10, when an in-place sensor of the conveyor 10 senses that a first product reaches a preset position and then stops running, at the moment, the robot 20 receives a signal, clamps the product from the conveyor 10, feeds the product into the punching die 40 along a guide block according to a set program, at the moment, the encoder 23 senses whether the position of the product is displaced in the Y direction relative to the chuck 22 or not, if the product and the chuck 22 generate relative displacement in the direction, the punch 30 cannot receive a working signal, the robot 20 takes out the product and places the product, and the original point is returned to execute action again. If no relative displacement in the Y direction is generated between the product and the chuck 22, after the robot 20 finishes the feeding action, the control system outputs a punching signal to the punch 30, the punch 30 executes the punching action, after the punching action is finished, the control system outputs a signal to the robot 20, the robot 20 pulls out the product from the punching die 40 and moves the product to the next station, the operation is sequentially circulated until the punching of the product is finished, the robot 20 grabs the product and moves the product to an inspection table and puts down the product, and an operator performs inspection operation, so that the whole process is finished. The Y direction means a direction in the vertical direction, which is perpendicular to the direction in which the conveyor conveys the automotive weatherstrip product.

The encoder 23 operates on the principle: the encoder 23 rotates at a certain speed and generates a stable pulse signal, when the product on the chuck is displaced in the Y direction, the encoder 23 generates a friction force with the product, the encoder 23 senses a corresponding change, the rotating speed is changed, the generated pulse signal is also changed and unstable, and a corresponding program is started, so that a working signal transmitted to the punch 30 is shielded. The utility model discloses a by installation encoder 23 at chuck 22, detect the position of product, can make die-cut position more accurate, die-cut quality is more stable, has reduced the risk of flowing the defective products, reduces the product disability rate, has practiced thrift the human cost.

Preferably, the encoder 23 is mounted on the cartridge 22 by an L-bracket 24 to facilitate mounting and adjustment of the encoder 23.

Preferably, the conveyor 10 includes a frame 11 and at least two endless belts 12 mounted on the frame 11, each endless belt 12 is provided with a plurality of positioning blocks 13, and corresponding positioning blocks 13 of the at least two endless belts 12 form a placing cavity for placing and conveying the automotive sealing strip product.

As shown in fig. 1, the number of the endless belts 12 is 3. The product crossbearers are positioned on the circulating belt 12 through the positioning blocks 13 and then conveyed to a designated position along with the circulating belt 12. The rotation of the endless belt 12 is driven by a drive wheel and a motor.

Preferably, the conveyor 10 is provided with a positioning cylinder, a positioning rod mounted at an execution end of the positioning cylinder, and an in-place sensor mounted at one end of the conveyor 10 close to the punching die 40, wherein the execution end of the positioning cylinder is vertically upward. After the position sensor senses that the first product reaches a preset position, the execution end of the positioning cylinder extends out to block the product, the circulating belt 12 stops rotating, and the robot 20 clamps the product in place; after the robot 20 has picked the product, the endless belt 12 is rotated to bring the next product to the desired location.

Preferably, the sensing end of the encoder 23 faces the automotive weatherstrip product of the cartridge 22, facilitating the encoder 23 to sense the Y-axis displacement of the product.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
