Description
Technical Field
The invention belongs to the technical field of dismounting equipment, and particularly relates to an automatic wire dismounting machine for a heat exchanger core brazing wire bundle.
Background
The automotive heat exchanger core is made of aluminum material. After the parts forming the core are processed separately and assembled, the parts are sent into a brazing furnace for brazing, so that scattered aluminum parts are welded into a whole, and the service life of the heat exchanger core product is prolonged.
During brazing, aluminum materials can exhibit uncontrolled amounts of plastic deformation. Therefore, before the heat exchanger core is fed into a brazing furnace, the heat exchanger core needs to be subjected to wire bundling reinforcement presetting, so that the plastic deformation is controlled in a controllable interval, and the core meets the product quality requirement.
The main board, the side boards and the wing strips in the core body are all aluminum sheets and are easy to deform by external force. In order to prevent the core body from being damaged due to the external force action of the core body binding wires in the binding procedure, two brazing square strips are respectively arranged at the upper end and the lower end of the core body side plate, and the core body side plate is protected and simultaneously plays a role in auxiliary shaping.
The core body is vertically equally divided into 4 sections, each section is bound by 1 iron wire, the full coverage of the iron wires is ensured, and the relative position relation of the core body assembly is reinforced.
After the brazing is finished, the heat exchanger core body completes all production process flows. The core body binding wires which play a role in fixing in the brazing and transportation processes are required to be removed, and the brazing square strips are peeled off.
Because the aluminum core finished product has certain product tolerance, the production tolerance accumulation of each part of the product is reflected on the whole product. The wire positions of the 4 wire positions of each core body are different from those of the standard component, and certain position deviation can occur. After the brazing is carried out, the offset of each bundle wire is +/-15 mm, the displacement variation is large, and the diameter of the iron wire is only 1.5mm. And the offset is an unordered state.
The prior art is to manually remove 4 binding wires in sequence by using a clamp and manually peel off two brazing square strips and recycle. Each core needs a long time to manually finish the process, and the efficiency is low. Because the binding wires are tightly attached to the surface of the core body, the surface of the core body is easily scratched in the process of manually removing the binding wires.
In conclusion, the technology has the problems of low efficiency, high cost and high rejection rate.

The X-axis adjusting mechanism 27 and the Y-axis moving device 22 of the present invention can realize positional adjustment in both the horizontal and vertical directions. When the workpiece of the core 9 is conveyed to the working position, the image photographing and image processing device photographs the wires carried by the core 9, so that the transverse displacement deviation of each wire compared with the wire corresponding to the standard component is obtained. The X-direction position coordinate data of the wire bundle of the core 9 is transmitted to a system, and the system controls an X-axis adjusting device in the wire bundle position adjusting drive device to adjust to a position right above the wire bundle position, and waits for cutting of the wire bundle. After the wire is cut, the X-axis adjusting mechanism 27 acts, and the wire clamping jaw assembly 28 moves the cut wire to the left and right ends respectively, so that accurate wire withdrawal is realized, and the iron wires are prevented from scratching the surface of the core 9. The lower Y-axis moving device 22 is driven to slightly adjust the positional relationship back and forth.
The Y-axis moving devices 22 may be provided in plural numbers (one for each wire bundle), each Y-axis moving device 22 corresponding to one wire bundle jaw assembly 28. Each Y-axis moving device 22 comprises a servo motor driven by a belt to rotate a screw rod, so that guide rails are used for guiding, a wire bundling clamping jaw assembly 28, a shearing device 24, a floating clapping device 29 and a magnetic attraction assembly are arranged below the Y-axis moving devices 22, and therefore accurate positioning of the magnetic attraction assembly, the clamping and cutting device relative to the Y-axis of the iron wires is achieved.

The up-and-down slight floating amount of the magnet 25 can be realized through the elastic structure, so that elastic contact is realized when the pneumatic clamping jaw 23, the shearing device 24 and the magnetic attraction component are contacted with the surface of the core 9. Because the core 9 is plastically deformed after welding, the surface of the core 9 is uneven, uncontrollable height difference exists, and the phenomenon that the core 9 is scrapped because the core 9 with the minimum height is suitable for being produced by the height difference, and when other height cores 9 are subjected to flat wire cutting, hard contact is generated, and the surface of the core 9 is indented during the hard contact.

The core 9 and the brazing square strip are conveyed to the area to be extracted by a lifting longitudinal moving rail 15 of the longitudinal moving mechanism. The lifting and longitudinally moving rail 15 descends, the core 9 falls on the supporting protrusions 13 of the fixed rails 2, and the brazing square strip is still on the lifting and longitudinally moving rail 15 and descends together with the lifting and longitudinally moving rail 15 because the length of the brazing square strip is smaller than the distance between the two fixed rails 2. When the lifting and longitudinally moving rail 15 returns, the brazing square strips are contacted with the square strip baffle 30, blocked and fall into the brazing square strip storage vehicle 11 below the frame 1 for recovery.

The stop position of the magnet 25 is 2mm away from the surface of the core 9, and the left magnet 25 and the right magnet 25 adsorb two ends of the iron wire, so that the iron wire is separated from the surface of the core 9 to form a gap.
The left pneumatic clamping jaw 23 and the right pneumatic clamping jaw 23 of the wire clamping jaw assembly 28 clamp two ends of the iron wire.
The Z-axis lifting mechanism 8 ascends by 5mm, so that the wire detaching mechanism 7 ascends and drives the shearing device 24 to leave the core 9 for a certain distance.
