Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and specifically to an automatic welding device for rough blanks of perforated tubes. Background Technology

[0002] A fecal occult blood test (FOBT) is a tool used to quickly check for occult blood in stool. The FBT works by detecting occult blood in the stool, and 80% of colorectal cancer patients test positive. Therefore, regular FBT testing is an effective way to screen for colorectal cancer. The FBT is similar to a pregnancy test; patients can use it at home. It's simple to operate—just one tube and one press for results.

[0003] The demand for PU pipes in the current market is increasing, and the technical requirements for them are also becoming more stringent. Currently, PU pipe production is mostly semi-automated, with multiple processes handled separately, resulting in low efficiency and a low pass rate. Specifically, the welding of the rough blanks used for PU pipes is generally done semi-automatically or manually, placing them into the welding equipment for welding. The rough blank refers to a semi-finished product consisting of the PU pipe body, flux strip, and base, but not yet welded. This process has a low degree of automation and low production efficiency. Furthermore, because the position and angle of the rough blank are easily misaligned or loosened, leading to changes in the angle, the pass rate of welded products is low, resulting in inconsistent PU pipe production quality. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides an automatic welding device for rough blanks of POP tubes. By incorporating a rotating ultrasonic welding mechanism, a rotating gripping and feeding mechanism, a rough blank presence detection mechanism, and a POP tube rough blank positioning and welding mechanism that work together, the device enables rapid feeding and automatic welding of POP tube rough blanks. It also enables automatic correction and fixation of the POP tube rough blank position before welding, significantly improving the welding quality of POP tube rough blanks. The fully automatic production process is quick, greatly increasing production efficiency. The operation is simple and safe, thereby improving the production quality of POP tubes. This solves the problems of low production efficiency due to semi-automatic or manual feeding of POP tube rough blanks in the prior art, and the unstable welding quality of POP tube rough blanks caused by easy deviation of the POP tube rough blank angle.

The detection sensor can detect the distance of the detection shaft descending to contact the pupu tube blank. When there is a pupu tube blank in the pupu tube blank carrier, the descent of the detection shaft is blocked by the pupu tube blank and cannot continue to descend. At this time, it is determined that there is a pupu tube blank in the pupu tube blank carrier. When there is no pupu tube blank in the pupu tube blank carrier, the descent of the detection shaft will not be blocked by the pupu tube blank and will continue to descend. The height will be much lower than when there is a pupu tube blank. At this time, it is determined that there is no pupu tube blank in the pupu tube blank carrier.

The detection and positioning welding mechanism for the POP tube blank is fixed by an ultrasonic generator to complete the welding of the POP tube blank. It can realize the rapid feeding and automatic welding of the POP tube blank, and can realize the automatic correction and fixation of the POP tube blank position before welding, which greatly improves the welding quality of the POP tube blank.

It solves the problems of low production efficiency of semi-automatic or manual feeding of POP tube blanks in the existing technology, and the unstable welding quality of POP tube blanks due to easy deviation of the POP tube blank angle.
