[0027] It should be noted that the top of the tank body 100 matches the bottom of the tank cover 200. When the lifting end of the lifting device 300 drives the tank cover 200 to move downward onto the top of the tank body 100, relevant staff can lock the tank body 100 and the tank cover 200 tightly through the added lock.

[0028] The scraping device 500 includes a first driving motor 510, a reciprocating moving structure 520, a stabilizing structure 530, and a scraping ring 540.

[0029] Among them, the first driving motor 510 is arranged on the tank cover 200, the reciprocating moving structure 520 and the stabilizing structure 530 are respectively arranged on the inner wall of the tank body 100, and the reciprocating moving structure 520 is detachably connected to the output end of the first driving motor 510. The scraping ring 540 is respectively connected to the moving ends of the reciprocating moving structure 520 and the stabilizing structure 530, and the outer ring of the scraping ring 540 fits against the inner wall of the tank body 100.

[0030] It should be noted that when the tank cover 200 is separated from the tank body 100, the output end of the first driving motor 510 is separated from the driving end of the reciprocating moving structure 520. When the tank cover 200 is closed on the tank body 100, by adjusting the tank cover 200, the output end of the first driving motor 510 can be connected to the driving end of the reciprocating moving structure 520, such as by clamping or plugging.

[0031] The stirring device 400 is arranged at the center of the tank cover 200, and the stirring end of the stirring device 400 passes through the scraping ring 540 and extends into the tank body 100. The vibration motor 600 is arranged on the tank cover 200.

[0032] Specifically, when relevant staff perform the stirring operation on the solder paste, first, the relevant staff pour the solder paste to be stirred into the tank body 100, and then through the adjustment of the lifting device 300, the lifting end of the lifting device 300 drives the tank cover 200 to move downward to the top of the tank body 100, and finely adjust the position of the tank cover 200 so that the output end of the first driving motor 510 can be connected to the driving end of the reciprocating moving structure 520. At this time, the scraping ring 540 is close to the top of the tank body 100.

[0033] Then, the relevant staff start the stirring device 400 to stir the solder paste in the tank body 100. After the stirring is completed, the relevant staff discharge the solder paste in the tank body 100.

[0034] When the blanking is about to end, part of the solder paste adheres to the inner wall of the tank body 100 and the stirring end of the stirring device 400. Then, the relevant staff can start the first driving motor 510, so that the first driving motor 510 drives the reciprocating movement structure 520, and through the cooperation of the stabilizing structure 530, the scraping ring 540 can be made to scrape downward along the inner wall of the tank body 100, gathering the solder paste on the inner wall of the tank body 100 downward, and then stop the first driving motor 510.

[0035] Then, the relevant staff turn on the vibration motor 600 to accelerate the dropping of the solder paste on the stirring device 400, and through the lifting of the lifting device 300, the first driving motor 510 can be separated from the reciprocating movement structure 520. At the same time, the stirring device 400 moves upward following the tank cover 200, which is convenient for the relevant staff to observe the adhesion condition of the inner wall of the tank body 100 and the adhesion condition of the stirring device 400.

[0036] In an embodiment of the present utility model, an observation port 101 is provided on the tank body 100 from top to bottom, and a transparent acrylic board is embedded at the observation port 101 to facilitate the relevant staff to observe the internal situation of the tank body 100; a discharge port 102 is provided at the bottom of the tank body 100, and an electromagnetic valve for controlling opening and closing is provided on the discharge port 102. Supporting legs 103 are also provided at the bottom of the tank body 100.

[0038] Among them, the fixed plate 310 is arranged on the outer wall of the tank body 100, the rotating shaft 320 is rotatably arranged on the fixed plate 310 and extends vertically upward, the mounting plate 330 is arranged at the extending end of the rotating shaft 320, and the threaded rod 340 is threadedly connected to the mounting plate 330 and is rotatably connected to the support frame 201.

[0039] It should be noted that when the relevant staff adjust the position of the tank cover 200, by rotating the threaded rod 340, the threaded rod 340 can drive the support frame 201 and the tank cover 200 to move. After the bottom of the stirring device 400 completely disengages from the tank body 100, the relevant staff can rotate the rotating shaft 320 to rotate the tank cover 200 and the devices on the tank cover 200, which is not only convenient for feeding but also convenient for inspecting the devices on the tank cover 200.

[0040] In an embodiment of the present utility model, as Figure 3 shown, the reciprocating movement structure 520 includes a bidirectional lead screw 521, a lead screw slider 522 and a connection head 523.

[0041] Among them, the bidirectional lead screw 521 is vertically arranged in the tank body 100 through the connecting plate. The lead screw slider 522 is arranged on the bidirectional lead screw 521, and the connecting head 523 is arranged at the top of the bidirectional lead screw 521. Among them, the connecting head 523 is detachably connected to the output end of the first driving motor 510 through the limiting groove, and the lead screw slider 522 is embedded in the scraping ring 540.

[0042] It should be noted that a limiting block matching the limiting groove of the connecting head 523 is arranged at the output end of the first driving motor 510, so that after the first driving motor 510 is inserted into the connecting head 523, it can drive the connecting head 523 to rotate. When the connecting head 523 rotates, it can drive the bidirectional lead screw 521 to rotate, so that the lead screw slider 522 moves, so as to drive the connected scraping ring 540 to move.

[0043] To clearly illustrate the previous embodiment, in an embodiment of the present invention, as Figure 3 shown, the stabilizing structure 530 includes a stabilizing rod 531 and a rod sleeve 532.

[0044] Among them, the stabilizing rod 531 is vertically arranged in the tank body 100, and the rod sleeve 532 is slidably arranged on the stabilizing rod 531. Among them, the rod sleeve 532 is embedded in the scraping ring 540.

[0045] It should be noted that when the scraping ring 540 moves following the lead screw slider 522, the movement of the scraping ring 540 can drive the rod sleeve 532 to slide on the stabilizing rod 531, improving the stability of the scraping ring 540 during up and down movement.

[0046] In an embodiment of the present invention, as Figure 4 shown, the stirring device 400 includes a second driving motor 410, a stirring shaft 420 and blades 430.

[0049] It should be noted that relevant staff can start the second driving motor 410, so that the stirring shaft 420 rotates accordingly, thereby driving the rotation of the blades 430 to realize the stirring of the solder paste.

[0050] In summary, for the self-cleaning solder paste stirring device according to the embodiments of the present utility model, the scraping ring 540 of the scraping device 500 can move along the inner wall of the tank body 100, and can remove the residual solder paste on the inner wall of the tank body 100 from top to bottom. In addition, during the process of the stirring device 400 rising with the tank cover 200, through the action of the vibration motor 600, the residual solder paste on the stirring device 400 is effectively removed, realizing all-round automatic cleaning.
