Description

Technical Field

[0001] The utility model relates to the technical field of motor processing devices, in particular to a circulating soldering flux supply system. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. It can convert voltage signals into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. It has the characteristics of small electromechanical time constant, high linearity, and starting voltage. Its working principle can be simply summarized as: input control signal → servo controller → servo motor → output motion. The servo system consists of a servo motor, a servo controller, and a feedback device. When the servo motor receives a pulse signal, it will rotate an angle corresponding to a pulse to achieve displacement.

[0003] The structure of a servo motor is mainly composed of stators, rotors, encoders and other components. The stator of a servo motor is usually made of laminated silicon steel sheets, and two-phase or three-phase windings are embedded in the surface slots. These windings are used to generate a rotating magnetic field. The rotor is the rotating part of the servo motor, and its structure is related to the type of motor. For permanent magnet servo motors, the rotor is usually composed of permanent magnets, which rotate in the magnetic field generated by the stator.

[0004] Servo motors are widely used in many fields, such as industrial automation, electronic equipment, transportation, printing and packaging, and robots, etc. They have the advantages of high precision, high speed, strong adaptability, good stability, short dynamic response time, and good comfort. However, in the production process of servo motors, the coils of the stator core need to be connected in series and parallel to maximize the performance of the motor. The existing technology is to connect the motor coils in series and parallel through the built-in circuit of the PCB board, that is, the stator core needs to be installed with PCB first, and then the stator wire pins are connected by tin welding.

[0005] The first step of tin soldering involves dipping the components to be soldered into flux, that is, soldering the circuit board requires spraying or immersing the flux, but the flux feed in the prior art is mostly contained in a separate container, which has the problem of leakage and volatilization, and thus requires manual addition of flux to the container in a timely manner. The flux consumption needs to be manually monitored each time, which seriously hinders the welding efficiency.

[0006] Therefore, a new technical solution is urgently needed to solve the above technical problems. Utility Model Content

[0011] Furthermore, a liquid level detection device is also provided on the soldering flux box.

[0012] Furthermore, an overflow cover with a dipping groove is also provided on the top port of the overflow.

[0036] The utility model is further described in detail below based on the accompanying drawings and embodiments. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1 to Figure 3 As shown, the present solution provides a circulating flux supply system, comprising an overflow member 1 with an overflow cavity 101, wherein a feed distribution member 2 with a distribution cavity 201 is arranged in the overflow cavity 101, and a flux container 3 with a flux cavity 301 is arranged in the distribution cavity 201; an annular overflow groove 4 is formed between the feed distribution member 2 and the overflow cavity 101, an annular feed distribution groove 5 is formed between the flux container 3 and the distribution cavity 201, and a plurality of distribution holes 302 are opened on the side of the flux container 3;

[0038] An overflow reflux interface 103 and a first feed port 104 are provided on the bottom plate 102 of the overflow component 1, and a second feed port 202 corresponding to the first feed port 104 is provided on the bottom wall of the feed distribution component 2; the flux enters the annular feed distribution groove 5 through the first feed port 104 and the second feed port 202, and enters the flux cavity 301 through the distribution hole 302; after the flux in the flux cavity 301 overflows, it enters the annular overflow groove 4 and is discharged outward through the overflow reflux interface 103.

[0039] The first feed port 104 is located in the annular feed distribution groove 5 , and the overflow reflux interface 103 is located in the annular overflow groove 4 .

[0040] like Figure 4 As shown, it also includes a flux supply component 6 for inputting flux into the first feed port 104 and for recovering the flux refluxed through the overflow reflux interface 103 .

[0041] Specifically, the flux supply assembly 6 includes a flux box 601 for containing flux, and a flux pump 602 for transporting the flux in the flux box 601 to the first feed port 104; the flux box 601 is provided with a discharge interface 603, a reflux interface 604 and a feeding port 605, and a feeding cover 606 is provided on the feeding port 605.

[0042] The input end of the flux pump 602 is connected to the discharge interface 603 through a material pipe, and the output end of the flux pump 602 is connected to the first feed port 104; the reflux interface 604 is connected to the overflow reflux interface 103 through a material pipe.

[0043] In addition, a liquid level detection device 9 is also provided on the flux box 601. In the present embodiment, the liquid level detection device 9 may be a liquid level sensor for monitoring the remaining amount of flux in the flux box 601. When the amount is lower than a safe liquid level, an external alarm may be issued to remind the operator to add flux to the flux box 601 from the feeding port 605; or when the liquid level reaches the maximum liquid level safety value, an external alarm may be issued to remind the operator to stop adding flux to the flux box 601.

[0044] It should be noted that the implementation method of flux reflow in this embodiment includes:

[0045] First, in this embodiment, the height of the reflow interface 604 on the flux material box 601 is lower than the height of the overflow reflow interface 103, so that the flux can reflux under the action of its own gravity;

[0046] Second, when the flux pump 602 pumps the flux out of the flux box 601 , a negative pressure is formed in the flux box 601 , thereby sucking the overflowing flux into the flux box 601 .

[0047] The circulating supply of flux is finally achieved through the above two methods.

[0048] like Figure 1 and Figure 2 As shown, an overflow cover 7 with a dipping slot 701 is also provided on the top port of the overflow member 1 to prevent the soldering flux from overflowing.

[0049] A dripping platform 105 extending outward is arranged on the outer side of the top port of the overflow member 1, so that the components to be welded can drip after being dipped in the material, so as to discharge the excess soldering flux.

[0050] Specifically, the dripping platform 105 corresponds to the position of the dipping notch 701, so that the dipping and dripping of the parts to be welded can be completed on the same horizontal path.

[0051] As an optimization of the present embodiment, an n-shaped support 8 is further provided on the bottom side of the overflow member 1 , and the n-shaped support 8 is screwed to the bottom plate 102 by screws.

[0052] It should be noted that, in order not to affect the loading and overflow recovery operations of the flux supply assembly, a through hole 801 corresponding to the overflow reflux interface 103 and the first feed port 104 is opened on the n-shaped support 8 to facilitate the connection of the material pipe.

[0053] In order to ensure that the flux in this embodiment can evenly enter the flux cavity 301, and evenly enter the annular overflow groove 4 in the case of overflow, the overflow member 1, the feed distribution member 2 and the flux container 3 are all circular, and the centers of the circles are coaxial. There are multiple distribution holes 302, which are circumferentially arranged on the side of the flux container 3, and the distribution holes connect the annular feed distribution groove 5 with the distribution cavity 201.

[0054] As a connection method of the main core components in this embodiment, the flux container 3 is screwed to the feed distribution component 2, and the feed distribution component 2 is screwed to the overflow component 1.

[0055] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
