Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of welding in automobile manufacturing, and particularly relates to a detection and recovery device for a robot welding gun electrode cap after dismounting. BACKGROUND

[0002] In the welding process of current automobile manufacturing, after the robot welding gun automatically replaces the electrode cap, the common electrode cap recovery device is guided to a recovery box through a recovery pipe, and whether the electrode cap is successfully dismounted is confirmed by the way that the robot welding gun electrode rod touches a mechanical switch (or a proximity switch is used to detect whether there is an electrode cap on the electrode rod), and then the next action is performed.

[0003] However, the common electrode cap recovery device in the current industry has the problems that some electrode caps cannot smoothly reach the inside of the recovery pipe and are randomly dropped anywhere in the work station, which causes safety and quality risks, and the electrode cap cannot be detected and ensured to reach the recovery box. The use of the electrode rod to detect whether there is an electrode cap has the risk of judgment error, for example, the detection position deviation and the robot track deviation can all cause false signals, so that the next action is performed in the case that the cap dismounting is not successful, which causes a major failure and property loss. In addition, multiple detection actions are required before a signal is obtained, and time is consumed. SUMMARY

[0004] The technical problem to be solved by the application is to provide a detection and recovery device for a robot welding gun electrode cap after dismounting, which is safe and reliable and has high efficiency.

[0005] The application is implemented in the following manner:

[0006] A detection and recovery device for a robot welding gun electrode cap after dismounting comprises, from top to bottom, a horn recovery port, a horn recovery port fixing mechanism, a detection mechanism, a detection port fixing ring and an electrode cap collecting mechanism.

[0007] The electrode cap collecting mechanism comprises a top cover plate and a collecting shell connected to the top cover plate.

[0008] The detection mechanism comprises a non-metal connecting sleeve, a proximity switch, a support, a recovery port switch piece and a cylinder. The non-metal connecting sleeve is installed with the proximity switch, the upper part of the non-metal connecting sleeve is connected to the horn recovery port fixing mechanism, and the lower part is fixedly connected to the detection port fixing ring. The support is fixed below the top cover plate of the electrode cap collecting mechanism, the support is provided with the recovery port switch piece, and the recovery port switch piece is connected to the cylinder. When the recovery port switch piece detects that the electrode cap falls thereon, a signal is sent to the cylinder, and under the action of the cylinder, the recovery port switch piece slides on the support, so that the detection port fixing ring is opened, and the electrode cap falls into the electrode cap collecting mechanism.

[0009] Further, the loudspeaker recycling port fixing mechanism comprises a fixing rod, an adjusting rod, an adjusting rod support and a V-shaped connecting support.

[0010] The bottom of the fixing rod is locked on the fixing platform by screws.

[0011] One end of the adjusting rod is provided with a ring-shaped port, and the other end is connected with the fixing rod perpendicularly through the adjusting rod support; the ring-shaped port is fixed at the bottom of the loudspeaker recycling port.

[0012] One end of the V-shaped connecting support is longer than the other end, the shorter end of the V-shaped connecting support is fixed beside the ring-shaped port of the adjusting rod, and the longer end is close to the outer side of the loudspeaker recycling port.

[0013] Further, the adjusting rod support comprises a sleeve part and a U-shaped support part arranged at the side of the sleeve part; the sleeve part is sleeved and threadedly connected on the fixing rod, and the other end of the adjusting rod passes through the U-shaped support part and is fixed by screws.

[0014] Further, the collecting shell of the electrode cap collecting mechanism is further provided with a pullable electrode cap collecting box.

[0015] The present application has the advantages that the present application detects the electrode cap when the electrode cap automatically reaches the recycling box entrance to determine whether the electrode cap is successfully disassembled, and transmits a correct signal to the robot for the next action, thereby avoiding the loss caused by the false signal and saving the movement time of the robot action welding gun for detection, and ensuring that each electrode cap can be successfully recycled. The present application has a large electrode cap collecting range and ensures the success rate of recycling; the electrode cap can be guided to the recycling port and stopped, and the proximity switch can successfully detect the electrode cap; the signal of the proximity switch detecting the electrode cap provides accurate and correct instructions for the robot welding gun, thereby ensuring the reliability of the signal. The opening time of the cylinder is given when the electrode cap is detected, and the detection and signal transmission process takes very short time, thereby ensuring the production rhythm.

[0022] The electrode cap collection mechanism 5 comprises a top cover plate 51 and a collection shell 52 connected with the top cover plate 51.

[0023] The detection mechanism 3 comprises a non-metal connecting sleeve 31, a proximity switch 32, a support 33, a recovery mouth switch piece 34 and a cylinder 35. The non-metal connecting sleeve 31 is installed with the proximity switch 32. The upper part of the non-metal connecting sleeve 31 is connected with the horn recovery mouth fixed mechanism 2, and the lower part is fixedly connected with the detection mouth fixed ring 4. The support 33 is fixed below the top cover plate 51 of the electrode cap collection mechanism 5. The support 33 is provided with the recovery mouth switch piece 34, and the recovery mouth switch piece 34 is connected with the cylinder 35. When the recovery mouth switch piece 34 detects that the electrode cap falls thereon, a signal is sent to the cylinder 35 and the robot welding gun. Under the action of the cylinder 35, the recovery mouth switch piece 34 slides on the support 33, so that the detection mouth fixed ring 4 is opened, and the electrode cap falls into the electrode cap collection mechanism 5. The robot welding gun performs the next action.

[0024] The horn recovery mouth fixed mechanism 2 comprises a fixed rod 21, an adjusting rod 22, an adjusting rod support 23 and a v-shaped connecting support 24. The bottom of the fixed rod 21 is screwed on a fixed platform (which can be the ground or the base of the welding gun grinder). One end of the adjusting rod 22 has a ring-shaped mouth 221, and the other end is connected with the fixed rod 21 perpendicularly through the adjusting rod support 23. The ring-shaped mouth 221 is fixed at the bottom of the horn recovery mouth 1. One end of the v-shaped connecting support 24 is longer and the other end is shorter. The shorter end 241 of the v-shaped connecting support 24 is fixed beside the ring-shaped mouth 221 of the adjusting rod 22, and the longer end 242 abuts against the outer side of the horn recovery mouth 1. The adjusting rod support 23 comprises a sleeve part 231 and a U-shaped support part 232 arranged on the side of the sleeve part 231. The sleeve part 231 is sleeved and screwed on the fixed rod 1. The other end of the adjusting rod 22 passes through the U-shaped support part, and is then screwed and fixed.

[0025] The collection shell 52 of the electrode cap collection mechanism 5 is further provided with a pullable electrode cap collection box 53.

[0026] Working process:

[0027] When the electrode cap on the robot welding gun falls into the horn recycling port 1, the proximity switch 31 below the horn recycling port 1 detects the electrode cap and sends a signal to the cylinder 35 and the robot welding gun. The cylinder 35 drives the recycling port switch piece 34 to move, opens the channel and makes the electrode cap fall into the electrode cap collecting box 53 of the electrode cap recycling mechanism 5; the robot welding gun performs the next action.

[0028] The present application detects the electrode cap when it automatically reaches the recycling box entrance, judges whether the electrode cap is successfully removed, and transmits the correct signal to the robot for the next action, avoiding the loss caused by the false signal, saving the movement time of the robot action welding gun for detection, and ensuring that each electrode cap can be successfully recycled. The present application can collect a large range of electrode caps and ensure the success rate of recycling; can guide the electrode cap to the recycling port and stop, ensuring that the proximity switch can successfully detect the electrode cap; through the signal of the proximity switch detecting the electrode cap, the robot welding gun provides accurate and correct instructions, ensuring the reliability of the signal. The detection of the electrode cap and the opening time of the cylinder are given at the same time, the whole detection and signal transmission process takes very short time, ensuring the production rhythm.

[0029] The above embodiments and drawings are not limited to the shape and style of the present application, and any appropriate changes or modifications made by those skilled in the art shall be considered as not departing from the scope of the present application.
