[0017] In practical use, the limiting rod 3 connected to the top of the support frame 2 is used to allow the side ears on both sides of the horizontal end of the support frame 2 to be inserted and fixed on the support frame 2, and the nuts 4 are threaded between the support frame 2 and the limiting rod 3 to fix the connection between the two.

[0018] Preferably, a circular through groove is provided on the bottom horizontal end surface of the support frame 2, and the shape and size of the through groove are adapted to the flux body 1.

[0019] In practical use, the circular through groove starting from the horizontal end of the support frame 2 is used to fix the position of the flux body 1 inserted thereon.

[0020] Preferably, the control panel 12 is connected to the first motor 11, the bottom of the support frame 2 is provided with a crossbar 13, the top of the crossbar 13 is equipped with a second motor 14, the transmission end of the second motor 14 is threadedly connected to a gear 15, and the bottom surface of the gear 15 is meshed with the top of the toothed plate 16.

[0021] In practical use, the second motor 14 starts to rotate at the same time, which causes the gear 15 connected to its transmission end to drive the toothed plate 16 connected to the bottom to move outward, so that the hose 18, which is sleeved on the rubber sleeve 17 at the front end of the toothed plate 16, is driven to move outward at a uniform speed, so that the electronic component surface placed horizontally on one side of the flux body 1 can be coated with flux at a quantitative and uniform speed.

[0022] Preferably, the toothed plate 16 is slidably connected to the top of the crossbar 13 at the bottom, a rubber sleeve 17 is bonded to the front surface of the toothed plate 16, the nozzle at the lower end of the hose 18 is sleeved on the inner wall of the rubber sleeve 17, and the open end of the top of the hose 18 is inserted into the bottom outlet of the flux body 1.

[0023] In practical use, the rubber sleeve 17 provided on one side of the toothed plate 16 is used to fit and fix the lower part of the hose 18 near the nozzle, which facilitates position adjustment. Since the hose 18 is made of elastic material, it is easy to move and bend it.

[0024] Preferably, the first motor 11, the control panel 12, and the second motor 14 form a control connection relationship.

[0025] In actual use, the control panel 12 is used to control the start-up, rotation number, and speed of the connected first motor 11 and second motor 14.

[0026] Preferably, the rubber sleeve 17 has a tubular structure, and the shape and size of the inner wall of the rubber sleeve 17 are adapted to the hose 18, and the shape and size of the top opening end of the hose 18 are adapted to the bottom outlet end of the flux body 1.

[0027] In practical use, the rubber sleeve 17 is used to connect and fix the end of the hose 18 near the nozzle, so as to facilitate the movement of the nozzle outlet position. Working principle: When soldering electronic components, select the appropriate flux body 1. Then, using the limiting rod 3 connected to the top of the support frame 2, the side ears on both sides of the horizontal end of the support frame 2 can be inserted and fixed onto the support frame 2. Nuts 4 are threaded between the support frame 2 and the limiting rod 3 to secure the connection. Next, insert the rubber head 5 into the open end of the top of the flux body 1. Use the connecting rod 6 to fix the connection between the rubber head 5 and the moving block 10. Then, according to the position of the electronic component to which flux needs to be applied, position the support frame 2 accordingly. The position of the hose 18, which is inserted into the bottom opening of the flux body 1, is adjusted according to its location so that the outlet end of the hose 18 can abut against the top of the electronic component that needs to be coated with flux. The first motor 11 and the second motor 14 are then controlled via the control panel 12. When the first motor 11 starts, the lead screw 9 connected to its transmission end drives the threaded moving block 10 to move downwards on one side of the mounting plate 7. This causes the threaded connecting rod 6 on the moving block 10 to drive the rubber head 5 to press downwards against the inner wall of the flux body 1. The position of the first motor 14 can be adjusted according to processing requirements. The rotation speed and number of rotations of the flux body 1 are adjusted to quantitatively extrude flux from the flux body 1 according to requirements. The extruded flux is pushed outward through the hose 18 connected below. At the same time, the second motor 14 starts to rotate, causing the gear 15 connected to its transmission end to drive the toothed plate 16 meshing at the bottom to move outward. This causes the hose 18, which is sleeved on the rubber sleeve 17 at the front end of the toothed plate 16, to move outward at a uniform speed. This allows the electronic components placed horizontally on one side of the flux body 1 to be quantitatively and uniformly coated with flux, thereby ensuring the subsequent... The quality of welding is ensured by reversing the second motor 14 after processing, thereby driving the toothed plate 16 back to its original position, which facilitates the subsequent movement of the nozzle of the hose 18. In this design, the first motor 11 and the second motor 14 are existing equipment, model number 17HS4401. Since they are existing technology and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution. The first motor 11 can control the number of rotations and speed of both motors according to the amount of flux to be extruded, thereby ensuring the quantitative extrusion of flux in the flux body 1.
