Description

Technical Field

[0001] The present invention relates to the technical field of welding waste collection devices, and particularly relates to an integrally formed welding waste collection device. Background Art

[0002] A welding jig refers to a fixture used to ensure the size of welded parts, improve assembly accuracy and efficiency, and prevent welding deformation. It is very commonly used in the process of welding mechanical parts. The workpiece to be welded is clamped and fixed by the welding jig, and then an external welding torch or laser is used to perform the welding operation on the workpiece. The welding jig plays a very important role in the welding process of the workpiece. At present, after the coil and the lead frame are laser welded, the excess waste leads remain on the welding jig. It is necessary to clean the welding waste on the surface and in the through holes of the welding jig after welding. The traditional cleaning process requires multiple processes such as stripping, brushing, primary air blowing, rolling brushing, and secondary air blowing. The process is extremely cumbersome. This not only leads to low cleaning efficiency, consuming a large amount of manpower, material resources, and time costs, but also consumes a huge amount of energy. At the same time, a large number of protruding parts on the surface of the welding jig are a major obstacle to the cleaning work. Due to the existence of these protruding parts, it is difficult for the cleaning tool to fully contact and remove the waste, resulting in a greatly reduced cleaning effect. The remaining waste will mix into the product during the secondary cyclic production, causing various product abnormalities such as short circuits and false soldering, greatly increasing the defective rate of the product, and there is a need for improvement. Summary of the Invention

When cleaning the waste, the end face of the rubber pad is flush with the surface of the welding jig.

[0009] The present invention is further configured as follows: The rotation and sliding assembly includes a rotating seat rotatably connected to the base and a rotating motor fixedly connected to the rotating seat. A second lead screw slide is fixedly connected to the rotating seat. Two sets of scraping scrapers and cleaning brushes are provided and symmetrically arranged on the sliding seat of the second lead screw slide.

[0010] The present invention is further configured as follows: The scraping scraper includes a supporting part fixedly connected to the sliding seat obliquely along the scraping direction and a plurality of arc-shaped scraping parts evenly arranged and fixedly connected to one end of the supporting part away from the sliding seat. The arc-shaped scraping part is tangent to the supporting part.

The intersection point of the first scraping plate and the second scraping plate coincides with the plane where the highest point of the arc-shaped scraping part is located. An arc-shaped bending part is fixedly connected to the arc-shaped scraping part in a tangent manner.

[0011] The present invention is further configured as follows: The included angle between the first scraping plate and the horizontal plane is between 75 and 90 degrees, and the included angle between the second scraping plate and the horizontal plane is between 15 and 35 degrees.

[0014] In summary, the present invention has the following beneficial effects: 1. The welding jig is arranged on the base based on the clamping and flipping assembly, and the thimble mounting assembly is arranged on the back of the welding jig based on the guiding and telescopic assembly. After welding is completed, first, the flipping motor drives the welding jig to flip 180 degrees so that the surface of the welding jig faces downward. Subsequently, the guiding and telescopic assembly drives the thimble to descend and insert into the jig hole to eject the residual welding waste in the jig hole. Due to gravity, most of the welding waste will fall off the surface of the welding jig. Finally, the rotating and sliding assembly drives the scraping blade and the cleaning roller brush to move reciprocally to scrape and clean the residual welding waste on the surface of the welding jig, greatly increasing the cleaning efficiency and effect of the waste. The clamping and flipping assembly adapts to the clamping and flipping requirements of welding jigs of different specifications by setting the first screw slide table and the synchronous clamping cylinder on the clamping seat.

By adjusting the position and angle of the first adjustment piece in the stepped adjustment groove and adjusting the position of the thimble in the locking adjustment groove, the cleaning requirements of the jig holes at any position on the welding jig can be achieved, greatly improving the adaptation range and having a simple structure. 2. The scraping blade evenly arranges a number of arc-shaped scraping parts on the supporting part, and a first scraping plate inclined along the scraping direction and a second scraping plate inclined in the reverse scraping direction are arranged on the arc-shaped scraping part, and an arc-shaped bending part tangent to the arc-shaped scraping part is arranged on the arc-shaped scraping part. When the scraping blade advances along the scraping direction, on the plane, the arc-shaped scraping part, the first scraping plate, and the second scraping plate abut against the surface of the welding jig. When moving to the protruding part, the arc-shaped bending part at the head abuts against the protruding part to drive the arc-shaped scraping part to bend and abut against the protruding part. At this time, the intersection of the first scraping plate and the second scraping plate abuts against and fits the side wall of the protruding part to clean the side wall and the bottom of the protruding part, realizing the complete cleaning of the residual welding waste. The movement direction of the scraping blade is adjusted by the rotating and sliding assembly to clean all the side walls of the protruding part. At the same time, a number of protruding flexible scraping plates are evenly arranged on the first scraping plate, the second scraping plate, and the arc-shaped scraping part, so that the contact area of scraping is larger, greatly improving the cleaning effect and avoiding the influence of waste on the workpiece.
