Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board surface soldering flux coating machine. Background Art

[0002] Flux is a chemical substance that promotes soldering. After the circuit board is produced, a layer of flux needs to be sprayed on the surface for subsequent processing.

[0003] The patent with the patent authorization announcement number CN203459212U discloses a selective PCB substrate flux sprayer, which includes a flux sprayer installed at the lower part of the transmission mechanism of the printed circuit board wave soldering machine and a sprayer control device. The slider of the horizontal fixed linear guide on the frame of the flux sprayer is connected to an "L"-shaped synchronous belt fixing seat; a horizontal reciprocating drive device consisting of a servo motor, a synchronous belt pulley, and a synchronous belt is installed under the frame, and a flux nozzle is installed on the upper end of the screw rod fixed on the horizontal plate of the "L"-shaped synchronous belt fixing seat on the outer synchronous belt between the two synchronous belt pulleys. When the flux is sprayed, the flux is easily sprayed to the inner wall of the equipment and the surface of the line. These flux residues may cause many problems such as aging and corrosion of the line insulation, thereby affecting the service life of the equipment.

[0004] Therefore, there is an urgent need to develop a circuit board surface flux coating machine that can prevent the flux from being sprayed onto the inner wall of the equipment and the circuit surface during spraying. Utility Model Content

[0013] Advantages of the utility model: 1. Place the circuit board on the placement plate, and position and limit the circuit board through the clamping plates on both sides.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Example 1

[0023] A circuit board surface flux coating machine, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a shell 1, a box door 2, a storage barrel 3, a connecting pipe 31, a nozzle 4, a square frame 5 and a placement component. The box door 2 is connected to the front side of the shell 1 through a hinge, two storage barrels 3 are installed on the upper part of the shell 1 through bolts, a connecting pipe 31 is connected between the lower parts of the two storage barrels 3, and a nozzle 4 for spraying flux is connected to the middle part of the connecting pipe 31. A square frame 5 is bolted in the shell 1, and the square frame 5 is located directly below the nozzle 4. A placement component is provided in the shell 1, and the placement component can place a circuit board.

[0024] When using the device, the staff opens the box door 2 and places the circuit board on the placement component. After placing it, the staff closes the box door 2 and then starts the equipment to spray the flux in the storage barrel 3 onto the surface of the circuit board through the nozzle 4. During spraying, the square frame 5 can prevent the nozzle 4 from spraying the flux onto the inner wall of the shell 1. After the spraying is completed, the staff closes the equipment and then opens the box door 2 to take out the circuit board after spraying.

[0025] like Figure 2 and Figure 3 As shown, the placement assembly includes a sliding plate 6, a placement plate 7 and a clamping plate 8. The sliding plates 6 are welded on both sides of the shell 1. The placement plate 7 is slidably connected between the left and right sliding plates 6. The clamping plates 8 are symmetrically welded on the upper side of the placement plate 7.

[0026] When using the device, the staff pulls the placement plate 7 to slide forward on the sliding plate 6. After pulling the sliding plate 6 forward, the staff places the circuit board to be sprayed on the placement plate 7. When placing it, the left and right clamps 8 can position the circuit board to prevent the circuit board from being tilted. After the circuit board is placed, the staff controls the placement plate 7 to slide backward and reset to allow for flux coating.

[0027] Example 2

[0028] On the basis of Example 1, Figure 1 , Figure 2 and Figure 3 As shown, it also includes a rotating plate 9, a pushing plate 10 and a vertical rod 11. The rotating plate 9 is connected to the left side of the shell 1 through a bearing, and the pushing plate 10 is welded to the lower left front side of the box door 2. The pushing plate 10 rotates to push the rotating plate 9 to rotate. The vertical rod 11 is slidably connected to the right part of the rotating plate 9 and is connected to the placement plate 7.

[0029] When using this device, the staff turns it forward to open the box door 2, and the box door 2 turns forward to drive the push plate 10 to swing backward. When the push plate 10 swings backward to contact with the rotating plate 9, the push plate 10 continues to swing backward to push the left part of the rotating plate 9 to rotate backward, and the right part of the rotating plate 9 rotates forward. The right part of the rotating plate 9 rotates forward and drives the placement plate 7 to slide forward and extend through the vertical rod 11. At the same time, the vertical rod 11 will also slide on the rotating plate 9. At this time, the staff can take out or put in the circuit board from the placement plate 7. After completion, the staff turns it backward to close the box door 2. When the box door 2 rotates backward to contact with the placement plate 7, the box door 2 continues to rotate backward to push the placement plate 7 to slide backward and reset. In this way, the placement plate 7 can be automatically pulled out and pushed back when opening and closing the box door 2.

[0030] like Figure 2 As shown, a mounting block 12 and an electric fan 13 are also included. The mounting block 12 is installed at the lower left position in the housing 1 by bolts, and the mounting block 12 is bolted to the electric fan 13.

[0031] When spraying the circuit board, the staff can start the electric fan 13 to air-dry the soldering flux sprayed on the surface of the circuit board through the electric fan 13. After completion, the staff turns off the electric fan 13.

[0032] like Figure 2 As shown, a baffle 14 is also included, and the baffle 14 is rotatably connected to the right part of the connecting pipe 31 and blocks the lower side of the nozzle 4.

[0033] When using the device, the staff rotates the baffle 14 to open it and no longer block the nozzle 4. After use, the staff rotates the baffle 14 to return it to its original position and continue to block the nozzle 4. In this way, the nozzle 4 can be prevented from being stuck with dust and affecting the flux coating effect.

[0034] like Figure 4 As shown, a scraper 15 is also included, and the scraper 15 is slidably connected in the square frame 5.

[0035] After the spraying is completed, the staff pushes the scraper 15 to slide up and down in the square frame 5, so as to scrape off the soldering flux sticking on the square frame 5.

[0036] like Figure 1 As shown, a handle 16 is also included, and the handle 16 is bolted to the right position of the front side of the box door 2.

[0037] When using the device, it is more convenient for the staff to hold the handle 16 to open and close the box door 2.
