[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figure 1-7 As shown, the utility model is an automatic welding production line for shear nails and ceramic rings, comprising a welding platform 1 and a steel plate guide groove 2 provided in the center of the upper end surface of the welding platform 1, and also comprising:

[0028] A linear motor 201 is symmetrically disposed on the upper end surface of the welding platform 1 and is located on the left and right sides of the steel plate guide groove 2;

[0029] The welding steel plate 3 is arranged inside the steel plate guide groove 2;

[0030] The walking gantry 4 is arranged at the upper end of the linear motor 201, and a six-axis robot automatic welding gun assembly 5 is arranged on one side of the walking gantry 4, and a shear pin and a ceramic ring discharge assembly 6 are arranged on the upper end surface of the walking gantry 4.

[0031] The shear pin and ceramic ring arrangement assembly 6 comprises a shear pin arrangement machine 601, a ceramic ring arrangement machine 602 and a pin-ring combination tool 603. The shear pin arrangement machine 601 is arranged on one side of the upper end surface of the walking gantry 4, the ceramic ring arrangement machine 602 is arranged on one side of the shear pin arrangement machine 601, and the pin-ring combination tool 603 is installed between the shear pin arrangement machine 601 and the ceramic ring arrangement machine 602. The shear pin and ceramic ring arrangement assembly 6 can be arranged in an orderly manner according to a predetermined posture.

[0032] First, the shear pin discharger 601 can put the shear pins into the material bin of the machine. The push plate has a certain angle, and some of the shear pins can be stuck on the push plate. The push plate can move up and down, and the shear pins stuck on the push plate can be pushed onto the conveyor belt one level at a time. When the shear pins are transported to the discharge mechanism, the shear pins rely on gravity, the shear pin heads face down, and the nail caps will be stuck on the discharge mechanism, and come to the discharge cylinder with gravity. If the sensor detects that there is no material, the discharge cylinder will put a shear pin on the shear pin positioning mechanism, and the manipulator will grab the shear pin to the nail ring combination tooling 603. Secondly, the ceramic ring discharger 602 is covered with an insulation layer on the outside, which can effectively protect the temperature of the heated ceramic rings and keep the ceramic rings dry.

[0033] Secondly, the vibration plate in the ceramic ring discharger 602 will cause the ceramic rings in the hopper to rise along the spiral track through vibration until they are sent to the discharge port. In the process of rising, the ceramic rings will go through a series of track screening or posture changes, and finally enter the ceramic ring lifting and positioning position with the small mouth facing upward. When the sensor has a long-term detection signal, it means that the ceramic rings are full and the vibration plate stops vibrating; if there is no signal, it will continue to vibrate and feed. When the material-free detection device sends a signal, it means that the ceramic rings in the vibration plate have been used up, and the system prompts to add material;

[0034] At the same time, the swinging air claw 1 in the nail-ring combination tooling 603 can grab the ceramic ring and put it into the combination position by rotating. Then, the swinging air claw 2 grabs the shear nail and then moves forward through the rodless cylinder. The swinging air claw 2 puts the shear nail into the combination position by rotating, and the guide rod cylinder descends to perform the nail-ring combination. After the robot completes the grabbing, each cylinder is reset to perform the next nail-ring combination for subsequent processing. Finally, the six-axis robot automatic welding gun assembly 5 can complete the removal of nails, the installation of rings to the welding gun, and complete the welding of the welding steel plate 3.

[0035] A linear motor 2 401 is installed on the upper end surface of the walking gantry 4, and a base plate is fixed to the output end of the linear motor 2 401. The shear nail discharging machine 601, the ceramic ring discharging machine 602 and the nail ring combination tooling 603 are all fixedly arranged on the upper end surface of the base plate. The position of the base plate can be adjusted by the linear motor 2 401. Since the shear nail and the ceramic ring discharging assembly 6 are arranged on the upper end of the base plate, the welding steel plates 3 at different positions can be welded. A gantry frame 7 is arranged on one side of the walking gantry 4, and the gantry frame 7 is fixedly arranged on the upper end of the linear motor 1 201. A laser cleaning machine 701 is arranged on the upper end of the gantry frame 7. The position of the gantry frame 7 can be adjusted by the linear motor 1 201, and the upper end of the gantry frame 7 is also provided with a linear motor group, so that the welded points of the entire welding steel plate 3 can be cleaned;

[0036] Single-pulse bag dust collectors 8 are evenly arranged on one side of the upper end surface of the welding platform 1. A guide pipe 801 is connected to one side of the single-pulse bag dust collector 8. The guide pipe 801 can be adjusted in angle and can be arranged at the upper end of the steel plate guide groove 2. Single-pulse bag dust collectors 8 are arranged around the welding platform 1, the steel plate guide groove 2 and the linear motor 201 production line to purify the dust generated by shear nail welding and laser cleaning in the factory. The single-pulse bag dust collector 8 adopts a pulse blowing cleaning method, which has the advantages of good cleaning effect, high purification efficiency, large processing air volume, long filter bag life, small maintenance workload, and safe and reliable operation.

[0037] Working principle: First, it should be noted that due to the presence of rust on the surface of some welded steel plates 3, the surface of the steel plates should be derusted before welding to ensure welding quality and efficiency. The laser cleaning machine 701 can be used to laser derust the surface of the position where the shear nails are to be welded to ensure welding quality. At the same time, this automatic welding production line has a control module that can intelligently control the equipment;

[0038] Then, the worker hoists the steel plate to be welded into the steel plate guide groove 2 at the upper end of the welding platform 1. At the same time, the shear nail arrangement machine 601 and the ceramic ring arrangement machine 602 in the shear nail and ceramic ring arrangement assembly 6 transport the nail ring, and then assemble it through the nail ring combination tooling 603, and then send a signal to the six-axis robot automatic welding gun assembly 5 through the control end. After receiving the start signal, the robot controls the robot to take the nail and the ring and install them on the welding gun, and detects the presence signal of the nail and the ring through the incoming material detection device of the welding gun, and then sends these two signals to the software system respectively. After the welding gun is in place, the software system sends an arc starting signal to the robot PLC to control the welding gun to perform welding. After the welding action is completed for n seconds, the welding completion feedback signal is sent to the software through the robot PLC. The software system controls the welding gun to rise a specified distance, and the robot is linked with the gantry x-axis and y-axis to transport the robot and the welding gun to the next specified position, and repeat the previous cycle, and so on.

[0039] Secondly, the drawing of the steel plate 3 to be welded is imported into the equipment. The operator moves the laser cleaning gantry to the cleaning starting position and starts the equipment. The equipment starts point cleaning of the entire steel plate according to the coordinate information of the shear nails on the drawing. After cleaning a certain distance, the operator moves the shear nail welding gantry to the welding starting position and starts the equipment. The equipment starts shear nail welding of the entire steel plate according to the coordinate information of the shear nails on the drawing. After welding is completed, the equipment moves to the unloading waiting position, and the worker hoists the welded steel plate to the unloading area, repeating the previous cycle, and so on.

[0040] Finally, the single-pulse bag dust collector 8 is configured to clean the dust in the steel plate guide groove 2, and can purify the dust generated by shear pin welding and laser cleaning in the factory.

[0041] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
