[0027] Example

[0028] Reference Figure 1-Figure 4 The utility model provides a technical solution: an anti-reverse and anti-error detection device for automobile sheet metal stud screw welding, comprising a body 1 and an anti-reverse and anti-error detection mechanism 3, a support seat 2 is fixedly installed on the body 1, the anti-reverse and anti-error detection mechanism 3 comprises a cylinder 31 fixedly installed on the body 1, a welding machine 311 is fixedly installed on the protruding end of the cylinder 31, an upper electrode 312 is installed on the welding machine 311, a lower electrode 32 is fixedly installed on the support seat 2, and a fixture block 33 is stably installed on the top of the lower electrode 32.

[0029] In a preferred embodiment, the manager 4 is fixedly installed on the body 1, and the manager 4 is electrically connected to the welding machine 311. In order to realize automatic operation, the manager 4 is installed on the body 1. The internal system of the manager 4 can automatically control the operation of the cylinder 31 and the welding machine 311 to automatically weld the plates.

[0030] In a preferred embodiment, an upper stroke detector 5 is also installed on the body 1, and the upper stroke detector 5 includes a movable block 51 and a connecting plate 52. The movable block 51 is fixedly installed on the telescopic end of the cylinder 31, and the connecting plate 52 is fixedly installed on the body 1. The movable block 51 is arranged in a sliding connection inside the connecting plate 52. In order to prevent incorrect processing of the plate, an upper stroke detector 5 is installed on the body 1. The upper stroke detector 5 detects the downward moving distance of the upper electrode 312. If there is a difference in the descending stroke of the upper electrode 312, it can be identified if the difference exceeds 0.1mm, resulting in the triggering of the sensor in the manager 4, which senses the alarm and stops; upper stroke detection device: the detection accuracy is 0.1mm, thereby realizing the detection of anti-error processing of the plate.

[0031] In a preferred embodiment, a limiting rubber 6 is provided on the top of the clamp block 33, and a fastening screw 7 passes through the inside of the limiting rubber 6. The limiting rubber 6 is fixedly connected to the clamp block 33 by the fastening screw 7. A fastening pin 8 is installed on the clamp block 33, and the clamp block 33 is fixedly installed on the lower electrode 32 by the fastening pin 8. In order to facilitate the processing of the plate, the device installs a limiting rubber 6 on the clamp block 33. There is a certain height difference between the upper surface of the limiting rubber 6 and the upper surface of the clamp block 33, so that the plate can be placed, and according to this height difference, it can play an anti-rebound effect on the plate.

[0032] To meet the processing requirements, the position of the upper electrode 312 is made to correspond to the position of the lower electrode 32 , and the upper electrode 312 also corresponds to the position of the fixture block 33 .

[0033] The manager 4 is also electrically connected to the cylinder 31 and the lower electrode 32. The fastening screw 7 is made of titanium alloy, which is insulated and non-conductive. The positions of the upper electrode 312 and the lower electrode 32 correspond, and the screw can be installed on the plate through the upper electrode 312, which is easy to use.

[0034] Specifically, the working process or working principle of a device for detecting anti-reverse and anti-error welding of automobile sheet metal stud screws is as follows: in the process of welding sheet metal stud screws, the welding of the screws and studs in the positive direction and the reverse direction often occurs. The detection of anti-reverse and anti-error of the stud screws is often carried out by manual inspection, and manual identification cannot ensure 100% detection of erroneous parts, which brings about production problems such as misjudgment, affects production efficiency, increases production costs, and even causes bad outflow. Once outflow occurs, it will cause serious economic losses. Therefore, this device is designed to solve this problem.

[0035] By using the anti-reverse and anti-error clamp block 33 in conjunction with the upper stroke detector 5 on the welding machine 311, and realizing the detection of various abnormalities such as anti-reverse and anti-error in sheet metal stud screw welding through hardware, welding errors can be avoided. The specific operation is to connect the external power supply, place the plate on the clamp block 33, and install the screws on the plate. After the plate is stably placed, the welding machine 311 is pushed downward by the cylinder 31, and the upper electrode 312 is driven to move downward and contact the screw. By using the upper electrode 312 and the lower electrode 32 in combination, the screws can be welded to the plate to complete the processing.

[0036] During the processing of the plate, it is easy to place the plate incorrectly due to human operation. When the wrong placement occurs, it can be identified in two ways;

[0037] The first method is that when the plate is placed in reverse, the bottom of the plate cannot fit with the surface of the fixture block 33, and there will be an obvious gap between the two. The staff can observe the gap between the two to determine whether the plate is placed in reverse, so as to correct the placement of the plate in time. In this case, timely adjustments can be made to avoid making the plate into scrap;

[0038] The second method is to detect the moving stroke distance of the upper electrode 312 through the upper stroke detector 5, which is mainly to prevent the sheet metal studs and screws from being welded in reverse. The difference in the descending stroke of the upper electrode 312 is more than 0.1mm, which can be identified, causing the sensor in the manager 4 to be triggered, and the alarm is sensed and stopped; the upper stroke detection device: the detection accuracy is 0.1mm, which can correspond to various abnormalities such as anti-reverse and anti-error in sheet metal stud screw welding.

[0039] It should be noted that the cylinder 31 and the welding machine 311 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
