Description

Technical Field

[0001] The utility model relates to the technical field of electronic component processing, in particular to a post-soldering cooling device for a magnetic ring inductor. Background Art

[0002] A magnetic ring inductor is a coil with a magnetic ring. Because the coil has an inductive reactance to alternating current after being energized, it constitutes an electronic component inductor; a magnetic ring inductor is an electronic component component, and its main function is an electromagnetic induction conversion function. Magnetic ring inductors are mainly used in resonant circuits, bandpass filters, and bandstop filters. In the production and processing of magnetic ring inductors, soldering is a very important task. In the prior art, the soldering process of magnetic ring inductors is to sequentially set up four stations: preheating, soldering, drying, and cooling. The inductor pre-coated with flux is heated to a predetermined temperature, the inductor is tinned, the flux on the inductor is dried, and then cooled.

[0003] At present, the cooling of magnetic ring inductors after soldering is mainly carried out through air cooling. Common cooling equipment is usually in the form of a conveyor belt. A cooling fan is set on the top of the conveyor belt. The magnetic ring inductors after soldering are placed on the conveyor belt. During the conveying process, the solder is cooled by blowing air from the cooling fan. However, there are still some problems in conveying and cooling magnetic ring inductors through conveyor belts. If the magnetic ring inductors are placed end to end, although the cooling effect can be guaranteed, the cooling efficiency is low; if the magnetic ring inductors are placed on the conveyor belt, although the cooling efficiency can be improved, the magnetic ring inductors are stacked in a way that blocks each other, resulting in poor cooling effect. For this reason, we propose a magnetic ring inductor post-soldering cooling device to solve the above problems. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a post-soldering cooling device for a magnetic ring inductor, comprising a mounting frame, two sets of transmission shafts are movably installed inside the mounting frame, and two sets of transmission sprockets are fixedly sleeved on the outside of the transmission shafts, and the outsides of the two sets of transmission sprockets are meshingly sleeved with transmission chains, a plurality of magnetic ring inductor fixture strips are fixedly connected to the circumference of the transmission chain, and the magnetic ring inductor fixture strips are provided with evenly distributed placement grooves, and the magnetic ring inductor to be cooled is placed in the placement grooves, a servo motor is fixedly installed on one side of the mounting frame, and the servo motor is transmission-connected to the transmission shaft at the inner head of the mounting frame, and a plurality of cooling fans are fixedly installed on the top of the mounting frame.

[0006] As a further description of the above technical solution: the two groups of transmission shafts are respectively located at the head and tail of the inner side of the mounting frame, and the two groups of transmission shafts are connected to the transmission chain through transmission sprockets, and the transmission is transmitted through the transmission chain. The servo motor can synchronously drive the transmission sprockets on the head and tail transmission shafts to rotate, providing sufficient power for the rotation of the transmission chain. At the same time, the transmission chain is limited by the transmission sprockets on the two groups of transmission shafts to ensure that the transmission chain can rotate stably.

[0007] As a further description of the above technical solution: a plurality of mounting tooth plates are fixedly installed on the transmission chain, and the mounting tooth plates and the magnetic ring inductor fixture strip are fixedly connected by screws. By setting the mounting tooth plates and fixing the magnetic ring inductor fixture strip on the mounting tooth plates, it is ensured that the magnetic ring inductor fixture strip can be driven to move synchronously when the transmission chain rotates, thereby realizing the adjustment of the position of the magnetic ring inductor fixture strip and the magnetic ring inductor to be cooled.

[0008] As a further description of the above technical solution: bearing seats that cooperate with the transmission shaft are fixedly installed on both sides of the mounting frame, and the transmission shaft is movably installed inside the mounting frame through the bearing seats. The position of the transmission shaft is limited by the bearing seats to ensure that the transmission shaft is stably connected in the mounting frame and that the transmission shaft is stable when rotating.

[0009] As a further description of the above technical solution: a connecting back plate is fixedly installed on one side of the mounting frame close to the head transmission shaft, and the servo motor is fixedly installed on the connecting back plate by screws. A transmission box is provided at the output shaft position of the servo motor and one end of the head transmission shaft. The servo motor is connected to the head transmission shaft through the transmission box, and the transmission is performed through the transmission box.

When the transmission chain drives the magnetic ring inductor fixture bar to rotate to transport the magnetic ring inductor to be cooled, a plurality of cooling fans work to blow air downward, which can blow and cool the magnetic ring inductor to be cooled after soldering.

[0011] As a further description of the above technical solution: the cooling fan is vertically arranged on the top of the mounting frame, and the air outlet of the cooling fan faces the mounting frame, the spacing between the cooling fan and the mounting frame is 20-40cm, and the cooling fan is installed by positioning the bracket and installing the horizontal bar to ensure that the cooling fan is firmly installed and can work stably, thereby realizing efficient cooling of the moving magnetic ring inductor to be cooled.

[0024] In this embodiment: Currently, the cooling of magnetic ring inductors after soldering is mainly carried out through air cooling. Common cooling equipment is usually in the form of a conveyor belt, and a cooling fan is set on the top of the conveyor belt. The magnetic ring inductors after soldering are placed on the conveyor belt, and the solder is cooled by blowing air from the cooling fan during the conveying process. However, there are still some problems in conveying and cooling the magnetic ring inductors through a conveyor belt. If the magnetic ring inductors are placed end to end, although the cooling effect can be guaranteed, the cooling efficiency is low; if the magnetic ring inductors are placed on the conveyor belt, although the cooling efficiency can be improved, the magnetic ring inductors are piled up and blocked by each other, resulting in poor cooling effect. In order to solve this technical problem, a transmission chain 5, a magnetic ring inductor fixture bar 7, and a placement slot 8 are added to this application document.

A servo motor 14 is fixedly installed on one side of the mounting frame 1, and the servo motor 14 is connected to the transmission shaft 3 of the inner head of the mounting frame 1. A plurality of cooling fans 12 are fixedly installed on the top of the mounting frame 1, and the magnetic ring inductors 9 to be cooled are clamped on the magnetic ring inductor fixture bar 7, and the transmission chain 5 and the magnetic ring inductor fixture bar 7 are driven by the servo motor 14 to rotate to transport the magnetic ring inductors 9 to be cooled, and at the same time, the cooling fan 12 can blow air to cool the magnetic ring inductors 9 to be cooled.
