The blocking device 4 is used to stop the parts to be detected at the end of the conveyor line to prevent the parts to be detected from falling from the conveyor line, and at the same time enable the subsequent lifting device to lift the parts to be detected. The lifting device is used to separate the parts to be detected from the conveyor line and lift them to a preset height, so that the parts to be detected can be at the same height as the image detection device 3, so that the image detection device 3 can locate the weld on the parts to be detected. In addition, the lifting device can also drive the parts to be detected to rotate at a preset speed. The image detection device 3 is used to locate the weld on the parts to be detected when the lifting device drives the parts to be detected to rotate, so as to facilitate subsequent weld detection work.

[0044] It should be noted that the image detection device 3 in this embodiment includes structures such as a light source and a detection probe, and locates the weld on the inspected part by collecting images and using a deep learning method using a high-performance server.

[0048] When in use, the blocking device 4 can stop the part to be detected at the opening, and then the telescopic member 21 drives the support platform 23 to extend from the opening and contact the lower surface of the part to be detected. After the support platform 23 contacts the part to be detected, the telescopic member 21 continues to drive the support platform 23 to extend so that the part to be detected can be at the same height as the image detection device 3. Afterwards, the drive motor 22 drives the support platform 23 to rotate slowly at a preset speed so that the image detection device 3 can fully locate the part to be detected.

[0056] The weld positioning device provided by the embodiment of the utility model is as follows: Figure 1 As shown, the lifting device further comprises a support rod 24. The support platform 23 comprises a plurality of horizontal rods 231, and all of the horizontal rods 231 are connected to one end of the support rod 24 and arranged in an X shape.

[0057] In this embodiment, the lifting device further includes a support rod 24 and a plurality of horizontal rods 231. All the horizontal rods 231 are arranged at one end of the support rod 24, and the other end of the support rod 24 is connected to the piston of the drive motor 22 or the telescopic member 21. In order to stably support the part to be detected, the horizontal rods 231 are arranged in an X shape.

[0058] As mentioned above, the support platform 23 , the drive motor 22 and the telescopic member 21 are arranged in sequence, so the end of the support rod 24 away from the horizontal rod 231 is connected to the output shaft of the drive motor 22 .

[0059] Optionally, in this embodiment, the horizontal rod 231 can be four square rods of equal length, and the ends of the four square rods of the same length are connected to one end of the support rod 24 away from the output shaft of the driving motor 22 and are arranged in an X shape.

The center of the longer square rod is connected to one end of the support rod 24 away from the output shaft of the driving motor 22, and the shorter square rod is connected to the center of the longer square rod.

[0061] Furthermore, in this embodiment, the horizontal rod 231 and the support rod 24 are vertically arranged, and the horizontal rod 231 and the support rod 24 can be connected by welding or riveting.

[0062] Preferably, in this embodiment, four horizontal rods 231 are provided, and any two adjacent horizontal rods 231 are vertically arranged. In other words, the support platform 23 is cross-shaped, so that the support platform 23 has the highest stability and the force on the test piece is most even.

[0063] Optionally, in this embodiment, the support platform 23 may also be a circular platform made of a circular plate, or the support platform 23 may also be a square platform made of a square plate, or the support platform 23 may also be six horizontal rods 231 in the shape of a " "Type, etc.

[0064] The weld positioning device provided by the embodiment of the utility model is as follows: Figure 1 As shown, the lifting device further includes a plurality of blocks 25.

There is sliding damping between the blocks 25 and the support platform 23, and the blocks 25 are used to fix the part to be detected on the support platform 23.

[0065] In this embodiment, the lifting device further includes a plurality of blocks 25, which are used to fix the part to be detected on the support platform 23. Specifically, a plurality of blocks 25 are provided, and all of the blocks 25 are arranged at intervals along the circumference of the support platform 23, and there is sliding damping between the blocks 25 and the support platform 23. When in use, when the part to be detected is located on the support platform 23, the block 25 is slid to make the block 25 abut against the part to be detected, so as to clamp and fix the part to be detected on the support platform 23, and prevent the part to be detected from falling off the support platform 23.

[0066] As mentioned above, the supporting platform 23 is in an X-shape, and thus, four stoppers 25 are provided, and a stopper 25 is slidably mounted on each side of the supporting platform 23 .

[0067] In this embodiment, there is sliding damping between the block 25 and the support platform 23, which can be achieved by increasing the friction between the block 25 and the support platform 23, or a locking member, such as a bolt, can be provided on the block 25. By means of the bolts abutting against the support platform 23, the purpose of increasing the sliding damping between the block 25 and the support platform 23 can also be achieved.

[0069] In the weld positioning device provided by the embodiment of the utility model, a deviation detection sensor is provided at the opening, and the deviation detection sensor measures the deviation between the support platform 23 and the opening.

[0070] In this embodiment, preferably, the shape of the opening corresponds to the shape of the support platform 23. For example, if the support platform 23 in this embodiment is cross-shaped, then the opening is also a cross-shaped opening.

[0071] During use, after the weld positioning is completed, the support platform 23 will be retracted into the opening under the action of the telescopic member 21. However, since the support platform 23 will rotate during use, the support platform 23 may not be aligned with the opening when it is retracted into the opening. Therefore, an offset detection sensor is provided at the opening to detect the offset between the support platform 23 and the opening when the support platform 23 is retracted into the opening, so as to determine whether the support platform 23 is aligned with the opening, and to avoid the support platform 23 from scratching the edge of the opening when it is retracted into the opening.

All the conveyor rollers are in transmission connection with the second driving member, and the second driving member is used to drive the conveyor rollers to rotate.

[0073] In this embodiment, the conveyor line includes a second driving member and a plurality of conveyor rollers. All conveyor rollers are arranged in sequence and spaced apart, and all conveyor rollers are transmission-connected to the second driving member, and the second driving member is used to drive the conveyor rollers to rotate. In order to form an opening at the end of the conveyor line, the length dimension of the conveyor roller portion at the end is smaller than the length dimension of the remaining conveyor rollers.

[0074] In this embodiment, by using the conveying roller as the conveying channel, the conveying efficiency is high and the cost is low. It is also convenient to open the opening at the end of the conveying line.

[0079] When in use, according to the size of the piece to be detected, the blocking rod 41 is moved to a predetermined position by the driving assembly. When the piece to be detected on the conveyor line contacts the blocking rod 41, the blocking rod 41 intercepts the piece to be detected on the conveyor line and is located exactly on the supporting platform 23.

[0080] Further, such as Figure 1 As shown, two blocking rods 41 are provided, and a preset angle α is formed between the two blocking rods 41 , wherein 0°<α<180°.

[0081] In this embodiment, two blocking rods 41 are provided, and a preset angle is formed between the two blocking rods 41 so that the center of the detected object can coincide with the center of the support platform 23 , thereby ensuring the stability of the detected object on the support platform 23 .

[0082] For example, in this embodiment, the part to be inspected is a wheel rim, and the angle between the two blocking bars 41 is 120°. When the wheel rim contacts the blocking bars 41, the wheel rim is displaced on the conveyor line under the action of the two blocking bars 41, and after the wheel rim stops moving, the center of the wheel rim coincides with the center of the support platform 23.

[0083] Optionally, in this embodiment, the blocking device 4 may also be a structure such as a blocking block slidably installed on the conveyor line.

[0084] The weld positioning device provided by the embodiment of the utility model is as follows: Figure 1 As shown, the driving assembly includes a screw rod, a crank handle and a connecting block. A slide rail is provided above the end of the conveyor line. The blocking rod 41 is slidably mounted on the slide rail and connected to the screw rod through the connecting block;

[0085] In this embodiment, the driving assembly includes a screw rod, a crank and a connecting block.

[0086] When in use, the screw rod can be driven to rotate by turning the crank, and then the blocking rod 41 is driven to slide on the slide rail through the connecting block.

[0087] In this embodiment, the screw rod has high precision, which is convenient for adjusting the position of the blocking rod 41. In addition, the screw rod is driven by a crank, which has high precision and is more convenient for operators to control the position of the blocking rod 41 compared to an electric drive method.

[0088] Preferably, in this embodiment, the extension direction of the slide rail is arranged parallel to the end of the conveyor line to facilitate the operator to adjust the position of the blocking rod 41.

[0089] Optionally, in this embodiment, the driving component may also be an electric motor or the like.

[0090] The weld positioning device provided by the embodiment of the utility model is as follows: Figure 1 As shown, it also includes a bracket, and the lifting device and the blocking device 4 are both arranged on the bracket.

[0091] In this embodiment, the lifting device and the blocking device 4 are arranged on the same bracket, so that the positions of the lifting device and the blocking device 4 can be adjusted conveniently.

[0092] The weld positioning device provided by the embodiment of the utility model is as follows: Figure 1 As shown, it is used to position the weld on the rim.

[0093] When in use, first adjust the position of the two blocking rods 41 by turning the crank according to the size of the rim. After the position adjustment of the blocking rod 41 is completed, the device can be started. Specifically, the rim is placed at the feeding end of the conveyor line, and the placement position of the rim does not need to be aligned with the cross-shaped opening. Under the action of the reduction motor, the conveying roller starts to rotate and conveys the rim to the end of the conveyor line, that is, the position of the cross-shaped opening. When the rim contacts the blocking rod 41, under the action of the two blocking rods 41, the rim moves to the top of the cross-shaped opening, and the axis of the rim is colinear with the axis of the cross-shaped opening. After that, the telescopic member 21 is started, and the telescopic member 21 drives the drive motor 22, the support rod 24 and the cross-shaped support platform 23 to rise. The cross-shaped support platform 23 extends from the cross-shaped opening and contacts the rim. After that, the telescopic member 21 continues to rise and stops moving after the rim and the image detection device 3 are at the same height. After that, the drive motor 22 starts to rotate, and the image detection device 3 is started at the same time to locate the weld on the rim. After the weld seam on the rim is positioned, the telescopic member 21 begins to retract. During the retraction process, the offset detection sensor detects whether the cross-shaped support platform 23 is aligned with the cross-shaped opening. If aligned, the telescopic member 21 continues to retract. If not aligned, the cross-shaped support platform 23 is driven to rotate by the driving motor 22 to align the cross-shaped support platform 23 with the cross-shaped opening. When the cross-shaped support platform 23 is retracted to the cross-shaped opening, the rim can be removed for the next process.
