Description

Technical Field

[0002] Tinning is a common process in the production of chip inductors. It is to apply a layer of tin on the metal surface to prevent oxidation and facilitate welding. At present, the flux dipping method used in the production of chip inductors is mostly to immerse several rows of inductors in flux at the same time. The robot will immerse the sorted multiple rows of inductors into the flux tank at one time, take them out and immerse them in the tin liquid again.

[0054] The present invention also discloses a method for using a soldering flux supply device for producing a patch inductor, comprising the following steps:

[0055] S1, the external workpiece transfer device grabs the workpiece and moves to a height corresponding to the position of the first push plate;

[0056] S2, the workpiece transfer device pushes the first push plate forward by a preset length to release the blocking of the baffle plate on the open opening of the material box;

[0057] S3, the workpiece transfer device moves downward to a preset height so that the workpiece contacts the sponge block and is stained with flux;

[0058] S4, the workpiece transfer device moves upward to a preset height, and the workpiece is higher than the top surface of the baffle;

[0061] In step S5, the spring pushes the second push frame to move back, and under the meshing transmission of the rack, the second gear and the first gear, the roller rotates to drive the first push frame to move upward, so that the flux overflows and rises to the bottom of the soaked sponge block; and under the elastic force of the spring, the first push frame self-locks and maintains at the height position.

[0062] It should be pointed out that when the baffle is in the blocking position, the piston head is in a high position, so that the flux is in the upper position of the material box, which effectively soaks the sponge block and effectively replenishes the flux on the sponge block; a clamping cavity is set on one side to expand the accommodating space at the top position. When the piston head is pushed upward, the upwardly moved flux will enter the clamping cavity, which can prevent overflow on the one hand and accelerate the contact and immersion with the sponge block on the other hand; and, when the piston head moves downward, the flux in the clamping cavity flows and gathers along the inclined material box, and the flux will not accumulate in the clamping cavity to affect the discharge of the flux when squeezing the sponge block; in actual use, it is necessary to add and supplement the flux regularly to ensure a sufficient amount of medicine, and try to make the flux and the sponge block fully contact when the piston head rises, so that the sponge block accumulates enough flux and the workpiece can be effectively adhered.

6. The soldering flux supply device for chip inductor production according to claim 5, characterized in that: The two ends of the roller strip are equipped with a first rotating shaft, the first rotating shaft rotates to penetrate the side wall of the material box, and the end of the first rotating shaft is equipped with a first gear; Racks are fixedly provided at the bottoms of both ends of the second push frame; A second gear is rotatably mounted on the outer wall of the material box, the second gear is located between the rack and the first gear, and the second gear is meshed with the first gear and the rack for transmission; When the second push frame is pushed by external force, the rack moves, driving the second gear and the first gear to rotate, driving the first push frame to move downward; When the external force is released, the second push frame returns to its original position and drives the first push frame to move upward.

7. The soldering flux supply device for chip inductor production according to claim 6, characterized in that: The second push frame includes a baffle, a first push plate is fixedly provided on the top of one side of the baffle, and at least two guide rods are installed on the first push plate; A support plate is vertically fixed on the top surface of the material box, the support plate is parallel to the first push plate, a guide hole is opened on the support plate corresponding to the guide rod, the guide rod is slidably inserted in the guide hole, and a retaining spring for preventing falling off is installed at the end of the guide rod; The spring is sleeved on the guide rod, and the spring clamp is arranged between the first push plate and the support plate; The bottom of the support plate is provided with a third through hole for movement of the baffle plate.

8. The soldering flux supply device for chip inductor production according to claim 7, characterized in that: A guide groove and a first threaded hole are provided at the top of both side walls of the material box, the first threaded hole is located on a side of the guide groove close to the support plate, and a first guide column is installed at the first threaded hole; The rack is provided with a second strip hole and a second threaded hole penetrating through the two side walls, the second strip hole extends corresponding to the moving track of the first guide column, the first guide column extends into the second strip hole and slides along the second strip hole; A second guide post is installed at the second threaded hole. The second guide post extends into the guide groove, and the second guide post slides along the guide groove.

9. A method for using the soldering flux supply device for chip inductor production according to claim 8, characterized in that: The steps include: S1, the external workpiece transfer device grabs the workpiece and moves to a height corresponding to the position of the first push plate; S2, the workpiece transfer device pushes the first push plate forward by a preset length to release the blocking of the baffle plate on the open opening of the material box; S3, the workpiece transfer device moves downward to a preset height so that the workpiece contacts the sponge block and is stained with flux; S4, the workpiece transfer device moves upward to a preset height, and the workpiece is higher than the top surface of the baffle; S5, the workpiece transfer device moves backward, the force applied to the first push plate is released, the second push frame moves back driven by the spring, and the cover plate resumes blocking the open opening of the material box; In step S2, during the movement of the second push frame, the rack drives the second gear to rotate, thereby driving the first gear to rotate, and the roller bar rotates to drive the first push frame to move downward, so that the flux flows downward and gathers below the bottom surface of the tray; In step S5, the spring pushes the second push frame to move back, and under the meshing transmission of the rack, the second gear and the first gear, the roller rotates to drive the first push frame to move upward, so that the flux overflows and rises to the bottom of the soaked sponge block; and under the elastic force of the spring, the first push frame self-locks and maintains at the height position.
