Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of SMT squeegee cleaning, in particular to an intelligent cleaning, detecting and storing integrated machine for SMT squeegees. Background Art
[0002] An SMT squeegee (Surface Mount Technology scraper) is a tool used in the production process of surface mount technology (SMT). In the SMT process, electronic components (such as resistors, capacitors, integrated circuits, etc.) are pasted on a printed circuit board (PCB), and the squeegee is used to paste solder paste onto the positions on the PCB. Solder paste is a material used to connect electronic components and the PCB. The function of the squeegee is to evenly scrape the solder paste on the surface of the PCB to ensure that a good connection is formed between the components and the PCB. In short, the SMT squeegee plays a key role in surface mount technology, helping to ensure the welding quality and reliability of components on the PCB.
[0003] When using the squeegee to apply solder paste, solder paste will remain on the surface of the squeegee. If not cleaned, the solder paste will accumulate and block the paste scraping groove of the squeegee, affecting the paste scraping effect. If the same squeegee is used for different types of solder paste or different PCBs, solder paste residue may cause cross-contamination, affecting the quality and consistency in the production process. Therefore, regularly cleaning the SMT squeegee is one of the important steps to maintain the SMT production quality and the equipment life. Summary of the Utility Model

Inside the machine platform, there are sequentially cooperating squeegee feeding modules 2, gantry handling robot modules 3, cleaning machines 4, squeegee vision handling modules 5, and vision detection modules 6. The squeegee feeding module 2 includes a storage rack body 201. At the bottom of the storage rack body 201, there is a storage plate 202 that can extend in and out along the squeegee feeding port 1 in the X-axis direction.

The gantry handling robot module 3 includes a three-axis moving machine 301 that moves along the X / Y / Z axes. A squeegee pick-and-place machine 302 is provided on the three-axis moving machine 301. The three-axis moving machine 301 drives the squeegee pick-and-place machine 302 to reciprocate between each material waiting cavity 204 and the cleaning machine 4. The squeegee pick-and-place machine 302 is used to take out the squeegees to be cleaned in the material waiting cavity, put the squeegees to be cleaned into the cleaning machine 4, and put the cleaned squeegees into the material waiting cavity 204. The vision detection module 6 includes a detection gantry 601. At the upper end of the detection gantry 601, there is a detection group 602. The detection group 602 is used to detect defects such as deformation and fracture of the squeegee blade edge.
[0030] The main steps of this technical solution are the feeding of the squeegee to be processed, the cleaning of the solder paste on the squeegee, and the surface detection of the squeegee to be processed.
[0031] The structural principle design for the feeding of the squeegee to be processed: There is a storage linear slide rail 205 inside the machine platform. Through the storage linear slide rail 205, the storage plate 202 can extend in and out along the squeegee feeding port 1 in the X-axis direction. First, the operator puts the squeegee to be processed into the material waiting cavity 204 on the infeed tray 203, and then puts the infeed tray 203 on the storage plate 202. Through the cooperation of the storage plate 202 and the storage linear slide rail 205, the feeding of the squeegee to be processed can be completed.
[0032] The structural principle design for the cleaning of the squeegee to be processed: There is a cleaning machine 4 inside the machine platform. Through the opening and closing slide rail 403 provided between the opening and closing plate 402 and the cleaning machine 4, the opening and closing plate 402 can close and open the cleaning cavity 401. During the opening process, the squeegee to be processed is put into the cleaning cavity 401, and a series of cleaning processes are carried out inside the cleaning cavity 401 to complete the removal of the solder paste on the squeegee.
[0033] For the surface detection of the squeegee; through the detection group 602 provided at the upper end of the detection gantry 601, the surface of the cleaned squeegee is detected by the camera structure 603, so as to distinguish between good products and defective products.
[0034] In the processes of feeding the squeegee to be processed, cleaning the solder paste on the squeegee, and surface inspection of the squeegee to be processed, the gantry handling robot module 3 and the squeegee vision handling module 5 are used to realize the transportation and transfer of the intermediate squeegee.
[0035] Regarding the structural principle of the gantry handling robot module 3: Inside the machine table, a three-axis motion slide rail system 303 that moves along the X / Y / Z axes with the gantry handling robot module 3 is distributed.

The gantry handling robot module 3 includes a three-axis motion machine 301 that moves along the X / Y / Z axes, and a squeegee pick-and-place machine 302 is provided on the three-axis motion machine 301. The three-axis motion machine 301 drives the squeegee pick-and-place machine 302 to reciprocate between each material waiting cavity 204 and the cleaning machine 4. The squeegee pick-and-place machine 302 is used to take out the squeegee to be cleaned in the material waiting cavity, put the squeegee to be cleaned into the cleaning machine 4, and put the cleaned squeegee into the material waiting cavity 204.
[0036] Regarding the structural principle of the internal cleaning of the cleaning machine: The squeegee cleaning positioning module is composed of a squeegee clamping jaw group 404, a turntable group 406 in the roller clamp 405, and a roller clamping block group 408. It moves in the X and Y axes to grab by the squeegee placing module, descends in the Z axis to grab the squeegee and then moves to the cleaning module. The squeegee clamping jaw descends and uses the intermediate guide block of the clamping jaw to press down the rolling bearing to drive the positioning module to open. It descends in the Z axis to the specified position, opens the grabbing clamping jaw and puts the squeegee in, so that the squeegee hole and the positioning pin are completely aligned, and then rises to the safe position in the Z axis. The squeegee cleaning positioning module rotates automatically and waits for the placement of the next squeegee to be cleaned. The squeegee clamping placement area 407 is set as six areas, that is, after filling six squeegees, the program runs automatically for cleaning.
[0037] Regarding the structural principle of the squeegee vision handling module 5: A moving frame body 501 is provided in the opposite direction on the same horizontal plane as the storage board 202. A moving linear slide rail 504 is provided between the lower end of the moving frame body 501 and the bottom plate of the storage frame body 201.

The upper end of the moving frame body 501 is provided with a rotating plate group 502, and a detection pick-and-place group 503 is provided on the rotating plate group 502. The rotating plate group 502 can drive the detection pick-and-place group 503 to rotate and extend into the material waiting cavity 204, and rotate the detection pick-and-place group towards the detection range of the detection group 602. The detection pick-and-place group 503 is used to take out the cleaned squeegee from the material waiting cavity 204 and put the qualified product after the squeegee is inspected into the material waiting cavity 204.
[0038] After cleaning and inspection are completed and good products are distinguished from defective products, the good products and defective products need to be transported, screened, and stored.
