[0011] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0012] The utility model is described in detail below in conjunction with specific implementation methods:

[0013] like Figure 1 The circuit board soldering cleaning agent mixing device shown in the figure comprises a base 1, an upper loading plate 2, a feeding barrel 3, a connecting rod 4, a first limiting ring 42, a spring 43, a homogenizing tank 5, a corrugated telescopic tube 6, a sleeve 61, a bearing seat 7, a first electromagnet 8 and a second electromagnet 9. The feeding barrel 3 is fixedly provided with a flange at the bottom, and the upper and lower ends of the connecting rod 4 are respectively fixedly connected to the feeding barrel 3 flange and the base 1. The upper loading plate 2 is slidably sleeved on the connecting rod 4, and the sleeve 61 is screwed and fixedly installed in the feeding barrel 3. The homogenizing tank 5 is fixedly installed on the upper loading plate 2. The homogenizing tank 5 is provided with a discharge channel 51 at the bottom, and a ball valve for controlling its opening and closing is provided on the discharge channel 51. The upper and lower ends of the corrugated telescopic tube 6 are respectively sealed and fixedly connected to the bottom of the sleeve 61 and the homogenizing tank 5. The connecting rod 4 is provided with a plurality of threaded holes 41 in a linear array. The first limiting ring 42 is slidably sleeved on the connecting rod 4. The first limiting ring 42 is fixedly installed in one of the threaded holes 41 by screwing. The spring 43 is sleeved on the connecting rod 4. The upper and lower ends of the spring 43 act on the first limiting ring 42 and the upper loading plate 2 respectively. The bearing seat 7 is fixedly installed on the connecting rod 4. The first electromagnet 8 is fixedly installed on the top of the bearing seat 7. The second electromagnet 9 is fixedly installed on the top of the upper loading plate 2. The second electromagnet 9 is located directly above the first electromagnet 8.

[0014] A second limiting ring 62 is fixedly installed in the feeding barrel 3 , and the entrance of the top opening of the second limiting ring 62 is set as an angled structure. The second limiting ring 62 can limit the extreme position of the installation of the sleeve 61 , and the angled structure can prevent powdered raw materials from accumulating on the top surface of the second limiting ring 62 .

[0015] A connecting plate 64 is fixedly installed in the top opening of the second limiting ring 62, and a feeding hole 65 is provided on the connecting plate 64. A stirring rod 63 is fixedly installed in the middle of the connecting plate 64, and a stirring wing is fixedly installed at the bottom of the stirring rod 63. The stirring wing is located in the middle position of the homogenizing tank 5, and the stirring wing is configured as a fan blade structure. When the homogenizing tank 5 moves up and down, the cleaning agent in the homogenizing tank 5 can improve the homogenization efficiency under the action of the stirring wing, and achieve a better homogenization effect.

[0016] A sealing end cover is hingedly installed on the top of the feeding barrel 3. During homogenizing oscillation, the sealing end cover is tightly installed on the top of the feeding barrel 3 to prevent the cleaning agent from overflowing from the top of the feeding barrel 3.

[0017] A guide rod 10 is fixedly installed on the bearing seat 7, and the upper loading plate 2 is also slidably sleeved on the guide rod 10. A stop ring 101 is also fixedly sleeved on the guide rod 10. The stop ring 101 is located at the lower part of the upper loading plate 2, and a rubber pad is fixedly installed on the top surface of the stop ring 101. The stop ring 101 can limit the extreme position of the downward movement of the upper loading plate 2. The rubber pad can avoid rigid contact between the upper loading plate 2 and the stop ring 101, thereby reducing noise. After the stop ring 101 and the rubber pad are damaged, they can be disassembled and replaced together with the guide rod 10. When the upper loading plate 2 contacts the rubber pad, there is a gap of 3-5 cm between the first electromagnet 8 and the second electromagnet 9.

[0018] The operator puts the mixture of rosin powder, triolamine, benzene hydrochloride and industrial alcohol into the homogenizing tank 5 through the feeding tube 3, and the first electromagnet 8 and the second electromagnet 9 are powered on and started. The magnetic pole of the first electromagnet 8 remains unchanged, and the second electromagnet 9 is an AC electromagnet whose magnetic pole changes periodically. When the magnetic poles of the second electromagnet 9 and the first electromagnet 8 are in a state of opposite poles attracting each other, the upper loading plate 2 moves downward together with the homogenizing tank 5. When the magnetic poles of the second electromagnet 9 and the first electromagnet 8 are in a state of same-level repulsion, the upper loading plate 2 moves downward together with the homogenizing tank 5 to overcome the elastic force of the spring 43 and move upward. The spring 43 can limit the upper loading plate 2 to the extreme position of the upward movement when the upper loading plate 2 moves up and down together with the homogenizing tank 5 periodically, the cleaning agent in the homogenizing tank 5 can be efficiently oscillated and homogenized, and the obtained cleaning agent can be discharged into the liquid storage barrel by opening the ball valve on the discharge channel 51.
