Description

Technical Field

[0001] This utility model relates to the field of inductor dispensing technology, specifically to a dispensing device for inductor production. Background Technology

[0002] Inductors play a crucial role in various circuit systems and are widely used. One type of inductor on the market consists of a pair of coils wound one turn after another around a toroidal ring. The toroidal ring is an insulating tube that insulates the coils from each other. After a certain number of turns, four leads are provided. To increase inductance, an iron core or magnetic powder core is usually placed inside the toroidal ring. These inductors are classified into three main categories based on their shape: baseless and plateless inductors, inductors with a base, and inductors with a base plate. In existing technology, such as... Figure 1 During the production of the inductor coil with a base shown, the iron core or magnetic powder core needs to be fixed in the inner cavity of the ring. Similarly, the ring with the coil wound on it needs to be fixedly connected to the base. The existing fixing method is mainly by dispensing glue, that is, by manually or by dispensing glue equipment at the connection position between the iron core or magnetic powder core and the base plate. After the dispensing operation is completed, glue residue will remain in the dispensing tube. When waiting to dispense glue for the next inductor, the glue residue in the dispensing tube will overflow onto the table or the inductor. This is difficult to clean and will also affect the production of the inductor. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a dispensing device for inductor production to address the deficiencies of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a dispensing device for inductor production, comprising a rotary worktable, a dispensing mechanism provided on one side of the rotary worktable, the dispensing mechanism comprising a mounting base, a lifting support column, a sliding crossbeam, a glue tank, a dispensing tube, and a return tube, the lifting support column being mounted on the mounting base and having a degree of freedom to move axially along the rotary worktable, the sliding crossbeam being slidably mounted on the lifting support column and having a degree of freedom to move radially along the rotary worktable, the glue tank being mounted on the top of the lifting support column, two dispensing tubes being mounted on the sliding crossbeam, the dispensing tubes being connected to the glue tank via a glue inlet hose, the return tube being connected to the side wall of the dispensing tube, the return tube being connected to a negative pressure pump, and the outlet of the negative pressure pump being connected to the glue tank.

[0005] Furthermore, a glue pump is installed on the glue tank, and the glue inlet hose is connected to the glue tank through the glue pump.

[0006] Furthermore, both the glue inlet hose and the glue return hose are equipped with one-way valves.

[0007] Furthermore, a first cylinder is vertically mounted on the mounting base, the telescopic shaft of the first cylinder is connected to the lifting support column, one end of the sliding crossbeam slides through the lifting support column, and a second cylinder is horizontally mounted on the lifting support column, the telescopic shaft of the second cylinder is connected to the sliding crossbeam.

[0008] Furthermore, a lead screw groove is provided on the sliding crossbeam, and a bidirectional threaded lead screw is rotatably installed in the lead screw groove. The axial direction of the bidirectional threaded lead screw is perpendicular to the moving direction of the sliding crossbeam. A lead screw slider is threadedly fitted on the two threaded sections of the bidirectional threaded lead screw with opposite thread directions. The lead screw slider is slidably adapted to the lead screw groove, and the two lead screw sliders are respectively connected to the two dispensing tubes through L-shaped connecting rods.

[0011] The beneficial effects of this utility model are:

Detailed Implementation

[0018] Example 1

[0019] like Figures 1 to 4 As shown, a dispensing device for inductor production includes a rotary table 1. A dispensing mechanism is provided on one side of the rotary table 1. The dispensing mechanism includes a mounting base 2, a lifting support 3, a sliding beam 4, a glue tank 5, a dispensing pipe 6, and a return pipe 7. The lifting support 3 is mounted on the mounting base 2 and has a degree of freedom to move axially along the rotary table 1. The sliding beam 4 is slidably mounted on the lifting support 3 and has a degree of freedom to move radially along the rotary table 1. The glue tank 5 is mounted on the top of the lifting support 3. The sliding crossbeam 4 has two dispensing tubes 6. The dispensing tubes 6 are connected to the glue tank 5 via an inlet hose 8. A return hose 7 is connected to the side wall of the dispensing tube 6, and a negative pressure pump 8 is connected to the return hose 7. The outlet of the negative pressure pump 8 is connected to the glue tank 5. A glue pump 9 is installed on the glue tank 5. The inlet hose 8 is connected to the glue tank 5 via the glue pump 9. The glue pump 9 pumps the glue from the glue tank 5 into the dispensing tubes 6 through the inlet hose 8. The glue is output from the end of the dispensing tube 6 to the connection point between the inductor pin and the base plate. The two dispensing tubes 6 respectively supply glue to the inductor pin. The two pins of the inductor are dispensing glue to complete the dispensing operation. This is existing technology and will not be elaborated further. However, after dispensing, glue residue remains in the dispensing tube 6. During the delivery of the next inductor to the dispensing station, glue residue in the dispensing tube 6 is prone to occur. Furthermore, the amount of residual glue in the dispensing tube 6 cannot be controlled, leading to inaccurate dispensing volume control. Therefore, after dispensing, the negative pressure pump 8 is activated. Under negative pressure, the residual glue in the dispensing tube 6 returns to the glue tank 5 through the return tube 7, thus avoiding... Residual glue overflows from the dispensing tube 6, ensuring that the amount of glue dispensed is not affected by residual glue, thus improving the accuracy of the dispensing amount. Due to the different models and sizes of inductors, the dispensing positions between the inductor and the base plate are different. The dispensing tube 6 is moved downward by the lifting support column 3, and the height of the dispensing tube 6 is adjusted so that it corresponds to the dispensing position of the inductor. The dispensing tube 6 is moved horizontally by the sliding crossbeam 4, moving closer to the dispensing position of the inductor so that the dispensing tube 6 can perform the dispensing operation, thereby adapting to the dispensing operation of various models of inductors.

[0020] Example 2

[0021] Based on Example 1, such as Figure 2 As shown, both the glue inlet hose 8 and the glue return hose 7 are equipped with one-way valves. The one-way valve on the glue inlet hose 8 ensures that glue can only be input from the glue tank 5 into the glue dispensing hose 6, and the one-way valve on the glue return hose 7 ensures that glue can only be input from the glue dispensing hose 6 into the glue tank 5. This prevents glue from entering the glue dispensing hose 6 from the glue return hose 7, and also prevents glue from entering the glue dispensing hose 6 from the glue tank 5 when the glue is returned under negative pressure.

[0022] Example 3

[0023] Based on Example 2, such as Figure 2 and Figure 4 As shown, a fixed base 16 is provided below the rotary worktable 1. A main shaft 17 is rotatably connected to the top of the fixed base 16. The main shaft 17 is coaxially connected to the rotary worktable 1. A motor is installed inside the fixed base 16. The output shaft of the motor is connected to the main shaft 17, which drives the main shaft 17 to rotate. The main shaft 17 drives the rotary worktable 1 to rotate, completing the cyclic conveying of the inductor. Several tooling blocks 18 are installed on the top of the rotary worktable 1 along its circumference. Tooling slots 19 are formed on the top of the tooling blocks 18. An annular support platform 20 is fixed on the inner wall. The worker places the base plate in the tooling slot 19 and supports the base plate with the annular support platform 20. At this time, the top surface of the base plate is higher than the top surface of the tooling block 18, so that the dispensing position of the inductor is exposed for dispensing. Then, the lead of the inductor is inserted into the mounting hole of the base plate. Then, by rotating the worktable 1, the inductor is transported to the working position of the dispensing mechanism. Then, the dispensing mechanism dispenses and installs the inductor. After the dispensing is completed, the worker unloads the material, thus completing the cyclical inductor dispensing production.

[0024] Example 4

[0025] Based on Example 3, such as Figure 2 and Figure 3 As shown, a first cylinder 10 is vertically mounted on the mounting base 2. The telescopic shaft of the first cylinder 10 is connected to the lifting support column 3. One end of the sliding beam 4 slides through the lifting support column 3. A second cylinder 11 is horizontally mounted on the lifting support column 3. The telescopic shaft of the second cylinder 11 is connected to the sliding beam 4. The extension and retraction of the first cylinder 10 drives the lifting support column 3 to move up and down. The lifting support column 3 drives the dispensing tube 6 to move downward through the sliding beam 4 so that it can match the dispensing height of the inductor. The extension and retraction of the second cylinder 11 drives the sliding beam 4 to move horizontally, so that the sliding beam 4 drives the dispensing tube 6 to move closer to or away from the dispensing position of the inductor, thus completing the dispensing reset operation.

[0026] Furthermore, a screw groove 12 is provided on the sliding beam 4, and a bidirectional threaded screw 13 is rotatably installed in the screw groove 12. The axial direction of the bidirectional threaded screw 13 is perpendicular to the moving direction of the sliding beam 4. Screw sliders 14 are threadedly fitted on the two threaded sections of the bidirectional threaded screw 13 with opposite thread directions. The screw sliders 14 slide and adapt to the screw groove 12. The two screw sliders 14 are respectively connected to two dispensing tubes 6 through L-shaped connecting rods 15. One end of the bidirectional threaded screw 13 extends out of the sliding beam 4 and is connected to a nut. The hand-turned nut drives the bidirectional threaded screw 13 to rotate, causing the two screw sliders 14 to move linearly along the axial direction of the bidirectional threaded screw 13. The two screw sliders 14 move in opposite directions. The screw sliders 14 drive the dispensing tubes 6 to move through the L-shaped connecting rod 15, thereby adjusting the distance between the two dispensing tubes 6 so that the distance between the two dispensing tubes 6 is equal to the dispensing distance between the two leads of the inductor. This allows for simultaneous dispensing of the two leads of the inductor and can accommodate dispensing of various inductor models, improving dispensing efficiency.
