Description

Technical Field

[0001] The invention relates to the field of industrial welding robot positioning accuracy detection equipment, in particular to a one-key detection device for electrode origins on automobile seat frame products. Background Art

[0002] During the production process of automobile seat frame products, the spot welding robot on the welding line will often collide with the fixture due to equipment aging and unstable fixture positioning. Once a collision occurs, the origin position of the welding clamp will change, which will cause the welding trajectory of all products in the workstation to change, affecting the welding quality and accuracy of the products. To avoid the above problems, it takes a lot of time and manpower to readjust and proofread the welding program. Summary of the invention

[0003] The purpose of the present invention is to provide a one-key detection device for electrode origin on a car seat frame product to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A one-click detection device for electrode origin on automobile seat frame products comprises a device mounting plate, a fixed mounting block, an inner cone swing detection block and a sensor, wherein the fixed mounting block is detachably connected to the center position of the device mounting plate, the inner cone swing detection block is overlapped on the fixed mounting block, an inner cone hole is provided at the center position of the inner cone swing detection block, a high-precision scale is detachably connected to the four sides of the inner cone swing detection block, a plurality of sensor mounting blocks are detachably connected to the device mounting plate, the sensor mounting blocks correspond to the four sides of the fixed mounting block, and the sensor is embedded in the sensor mounting block.

[0006] Preferably, a clearance through hole is opened at the center of the device mounting plate.

[0007] Preferably, overlapping steps are processed on the four sides of the fixed mounting block.

[0008] Preferably, the inner cone swing detection block has overlapping legs on four sides, and the overlapping legs are adapted to the overlapping steps.

[0009] Preferably, an embedded groove is provided on the sensor mounting block, and the sensor is adapted to the embedded groove.

[0010] Preferably, a wedge-shaped groove is provided on the lower surface of the overlapping leg, and a rotatably arranged roller is passed through the overlapping step of the fixed mounting block through a positioning pin, and the roller is adapted to the wedge-shaped groove on the overlapping leg.

[0011] When the one-key detection device for electrode origin on automobile seat frame products is used, the device mounting plate is matched with the electrode grinder. When electrode detection is to be performed, the robot welding clamp is automatically moved to the inner cone hole position on the inner cone swing detection block through program control, the upper electrode is above the inner cone swing detection block, and the lower electrode is below the inner cone swing detection block. Then the program clamps the upper and lower electrodes, and the inner cone hole is a trumpet mouth that is wide outside and narrow inside. When the electrode is clamped, if the head of the electrode is offset from the origin due to collision or aging of the equipment, the electrode will touch the inner cone hole of the inner cone swing detection block, causing the inner cone swing detection block to be pushed and move, thereby triggering a highly sensitive sensor attached to the inner cone swing detection block, and the sensor sends a signal to the robot The PLC of the robot will stop moving immediately after receiving the signal to prevent the offset from being too large and causing a collision with the detection device. At the same time, an alarm will be sounded, and the technicians will come forward to analyze the cause and make adjustments. The offset of the XY axis can be viewed from the high-precision ruler. After the adjustment is completed, the welding procedure is manually performed once to complete the electrode alignment detection. The inner cone swing detection block is placed on the fixed mounting block, and the overlapping legs of the inner cone swing detection block cooperate with the rollers on the fixed mounting block through the wedge groove, so that the flexibility of the overlap between the inner cone swing detection block and the fixed mounting block is improved. When the inner cone swing detection block is pushed, it can be flexibly moved in position, and when the inner cone swing detection block is placed naturally, the wedge groove and the roller cooperate because of gravity, and the roller will automatically align with the top of the wedge groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the device is simple to operate, has high detection accuracy, and can be used in conjunction with a robot to reduce the debugging time of the equipment, thereby ensuring product quality while reducing the robot collision correction time and significantly saving labor costs.

[0019] Working principle: When using the one-key detection device for electrode origin, match the device mounting plate 1 with the electrode grinder. When electrode detection is to be performed, the robot welding clamp A automatically moves to the position of the inner cone hole 4 on the inner cone swing detection block 3 through program control. The upper electrode is above the inner cone swing detection block 3, and the lower electrode is below the inner cone swing detection block 3. Then the program will clamp the upper and lower electrodes B, and the inner cone hole 4 is a trumpet mouth that is wide on the outside and narrow on the inside. When electrode B is clamped, if the head of electrode B is offset from the origin due to collision or aging of the equipment, electrode B will touch the inner cone hole 4 of the inner cone swing detection block 3, causing the inner cone swing detection block 3 to be pushed and moved, thereby triggering the highly sensitive sensor 7 attached to the inner cone swing detection block 3. The sensor 7 sends a signal to the PLC of the robot. The robot will stop moving immediately after receiving the signal to prevent the offset from being too large and causing a collision with the detection device. At the same time, an alarm will be sounded, and the technician will come forward to analyze the cause and make adjustments. The offset of the XY axis can be checked from the high-precision scale 5. After the adjustment is completed, the welding procedure is manually performed once to complete the electrode alignment detection. The inner cone swing detection block 3 is overlapped on the fixed mounting block 2, and the overlapping legs 10 of the inner cone swing detection block 3 cooperate with the roller 12 on the fixed mounting block 2 through the wedge groove, so that the flexibility of the overlap between the inner cone swing detection block 3 and the fixed mounting block 2 is improved, and when the inner cone swing detection block 3 is naturally placed, the wedge groove cooperates with the roller 12. Due to gravity, the roller 12 will automatically align with the groove top of the wedge groove.
