[0045] The present embodiment provides an automatic flux mixing device, which can effectively control the ratio of ionized water, soldering powder and glue, avoid dust generation and improve operation efficiency.

[0046] like Figure 1As shown, the automatic flux mixing device mainly includes a soldering powder placing box 100, a first vacuum suction component 200, a weighing component 300, a soldering flux mixing barrel 400, a glue barrel 1000 and a second vacuum suction component 500. The soldering powder placing box 100 is used to hold soldering powder, the weighing component 300 includes a weighing barrel 310 and a weighing unit 320, the weighing barrel 310 is placed on the weighing unit 320, one end of the first vacuum suction component 200 is connected to the soldering powder placing box 100, and the other end is connected to the weighing barrel 310, the first vacuum suction component 200 can absorb the soldering powder in the soldering powder placing box 100 into the weighing barrel 310, and the weighing unit 320 is configured to weigh the soldering powder in the weighing barrel 310. The soldering flux mixing barrel 400 is connected to both the deionized water source 1100 and the glue barrel 1000, so that both deionized water and glue can be transported to the soldering flux mixing barrel 400. One end of the second vacuum suction component 500 is connected to the weighing barrel 310, and the other end is connected to the flux mixing barrel 400. The second vacuum suction component 500 can suck the soldering powder in the weighing barrel 310 into the flux mixing barrel 400 to mix the soldering powder, deionized water and glue to prepare a flux solution.

[0047] Based on the above design, the automatic flux mixing device in this embodiment also includes a controller, which is electrically connected to the first vacuum suction component 200, the second vacuum suction component 500 and the weighing unit 320, and the controller can also control the flow rate of deionized water and the flow rate of glue. The operator can pre-set the proportion of the soldering powder, deionized water and glue required to configure the flux solution in the controller. When the automatic flux mixing device is operating normally, the controller can control the deionized water and glue to be transported to the flux mixing barrel 400 in turn according to the pre-designed weight ratio of the soldering powder, deionized water and glue, and then the controller can control the first vacuum suction component 200 to absorb the soldering powder in the soldering powder placement box 100, so that the soldering powder can be transported to the weighing component 300.

[0048] It should be noted that in order to ensure the continuity of the operation of the automatic flux mixing device, the weight of the soldering powder sucked by the first vacuum suction component 200 is usually greater than the pre-set weight of the prepared flux solution. This can avoid the first vacuum suction component 200 from repeatedly sucking soldering powder and improve work efficiency.

[0049] By designing the weighing assembly 300, the weighing unit 320 can weigh the solder powder sucked by the first vacuum suction assembly 200, and then the weighing unit 320 feeds back the data to the controller, which records and processes the data, and then controls the second vacuum suction assembly 500 to suck the solder powder in the weighing barrel 310. At this time, the weight of the solder powder sucked by the second vacuum suction assembly 500 is a preset weight, so that the weight of the solder powder delivered to the flux mixing barrel 400 is qualified. In other words, there is still some residual solder powder in the weighing assembly 300. Finally, the deionized water, glue and solder powder in the flux mixing barrel 400 can be prepared according to a preset ratio, and then a flux solution can be formed, so that it can be applied or adhered to the connector for use. The drawings in this embodiment do not show the connector.

[0050] The weighing assembly 300 in this embodiment can weigh the solder powder sucked by the first vacuum suction assembly 200, thereby ensuring that the solder powder delivered to the flux mixing barrel 400 meets the ratio requirements. Specifically, when the weight of the solder powder in the weighing barrel 310 is lower than the weight of the solder powder required for the flux solution preparation, the controller can control the first vacuum suction assembly 200 to suck the solder powder in the flux mixing barrel 400, so that the solder powder in the weighing barrel 310 reaches or exceeds the preset value.

[0051] Optionally, the flux mixing barrel 400 in this embodiment is provided with stirring blades for stirring the solution to improve the efficiency of preparing the flux solution.

[0052] It should be emphasized that the controller in this embodiment belongs to the prior art, and the technical solution in which the controller is electrically connected to the first vacuum suction component 200, the second vacuum suction component 500 and the weighing unit 320 belongs to the prior art. Therefore, the structure of the controller in this embodiment and the working principle of the controller controlling the first vacuum suction component 200, the second vacuum suction component 500 and the weighing unit 320 will not be described in detail.

[0053] Compared with the prior art, this embodiment realizes the automatic preparation of the flux solution by setting up the flux powder placement box 100, the first vacuum suction component 200, the weighing component 300, the flux mixing barrel 400, the glue barrel 1000 and the second vacuum suction component 500, and can accurately control the weight ratio of deionized water, glue and solder powder to improve the working efficiency. There is no need to manually mix the deionized water, glue and solder powder in the prior art, which avoids the dust phenomenon caused by the operator manually taking the solder powder, protects the environment and improves the working efficiency.

[0054] It should be noted that if the amount of solder powder added to the flux mixing barrel 400 by the second vacuum suction assembly 500 is greater than a preset value, the controller can control the delivery of glue and deionized water again. That is to say, the controller can add glue and deionized water again based on the extra solder powder, so that the performance of the configured flux solution remains unchanged.

[0055] like Figure 1 In the present embodiment, the automatic flux mixing device includes a first connecting pipe 600 and a powder suction plate 610. One end of the first connecting pipe 600 is connected to the first vacuum suction assembly 200, and the other end is connected to the powder suction plate 610.

The setting of the first bracket 3102 can support the barrel body 3101 at a certain height, so that the bottom of the barrel body 3101 is suspended, thereby facilitating the connection of the second connecting pipe 700. The setting of the inverted cone barrel body 3101 is conducive to the flow of the brazing powder in the barrel body 3101, avoiding the formation of a dead zone of the brazing powder in the barrel body 3101, and improving work efficiency.

[0059] like Figure 1As shown, in this embodiment, the automatic flux mixing device includes a second bracket 330, the second bracket 330 has a horizontal surface, and the weighing unit 320 is arranged on the horizontal surface, so that the weighing accuracy of the weighing unit 320 can be improved and the error can be reduced.
