Description

Technical Field

[0001] The utility model belongs to the technical field of NdFeB barrel plating, in particular to an automatic NdFeB barrel plating production line. Background Art

[0002] Neodymium magnets, also known as neodymium iron boron magnets, are a powerful permanent magnet material with an extremely high magnetic energy product, making them one of the strongest permanent magnets currently available. Their ability to generate a strong magnetic field in a compact size gives them irreplaceable advantages in numerous applications.

[0003] For example, the Chinese patent with the announcement number CN217809743U discloses an automatic production line for NdFeB barrel plating, comprising a plating box, a roller arranged near the center of the plating box, a slot arranged near the center of the surface of the roller, a limit slot arranged at the four corners of the inner end of the slot corresponding to the inner end of the roller, a standby plating slot arranged near the center of the inner end of the roller corresponding to the slot, a clamping plate arranged on the surface of the roller, the bottom of the clamping plate extending through the inner end of the slot and engaging with the slot. The automatic production line for NdFeB barrel plating can effectively improve the efficiency of NdFeB loading through the design of a feeding box, a feeding plastic tube, a clamping plate, a limit block, a slot, a limit slot and a fixing bolt. At the same time, the clamping and fixing structure facilitates the user to fix the NdFeB material. The operation is simple and convenient, which effectively improves the efficiency of NdFeB barrel plating, saves time and effort, and meets the needs of existing users.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, when the device is loading, the NdFeB material will directly enter the plastic tube after being poured into the discharge box, making it difficult to effectively control the outflow of the material, which is quite inconvenient. In addition, the clamping plate in the device needs to be fixed with multiple fixing bolts, which requires the operator to use a wrench to turn multiple fixing bolts, which is very time-consuming. In view of this, we propose an automated NdFeB barrel plating production line. Utility Model Content

[0006] The purpose of the utility model is to provide an automated NdFeB barrel plating production line to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a NdFeB barrel plating automated production line, comprising:

[0008] A U-shaped frame, wherein a roller is rotatably mounted in the U-shaped frame, a cover plate is plugged and mounted on the roller, a slot is provided on one side of the U-shaped frame and located on the cover plate, and a baffle contacting the cover plate is plugged and mounted in the slot;

[0009] A fixing assembly, the fixing assembly being located in the U-shaped frame and used to fix the baffle;

[0010] A driving assembly, the driving assembly being located on the U-shaped frame and being used to drive the drum to rotate;

[0011] A feeding shell is fixedly installed on the top of the U-shaped frame, three placement slots are opened in the feeding shell, a rotating plate is rotatably installed at the discharge port of the placement slot, and the three rotating plates are coaxially connected. A cavity is opened in the feeding shell and is located on one side of one of the placement slots. A motor is fixedly installed in the cavity, and the output shaft of the motor passes through one side of the cavity and extends into one of the placement slots and is coaxially connected to one of the rotating plates. Three discharge pipes are fixedly installed at the bottom of the feeding shell.

[0012] After the NdFeB material in the drum is loaded, the motor is started again so that the output shaft of the motor drives the three rotating plates to rotate 90° again. At this time, the discharge port of the three placement slots will be closed again, so that the NdFeB material in the placement slot will not enter the discharge pipe.

[0013] Afterwards, the cover plate can be inserted into the roller again through the slot, and then the baffle plate can be inserted into the slot, and then the fixing component can be used to fix the baffle plate in the slot. At this time, one side of the baffle plate will contact the cover plate, thereby fixing the position of the cover plate. Then, the driving component can be used to drive the roller to rotate, and the roller will drive the cover plate to rotate. Under the action of the U-shaped frame, the cover plate will not shake, ensuring that the entire device can work normally.

[0014] In the above technical solution, further, the fixing assembly includes:

[0015] A slide groove is opened in the U-shaped frame and is located on one side of the slot. A limit block is slidably installed in the slide groove. One end of the limit block passes through one side of the slide groove and extends into the baffle. The other end of the limit block is located in the slide groove and a pull rod is fixedly installed. One end of the pull rod passes through the other side of the slide groove and extends to the outside. A spring is sleeved on the pull rod and is located in the slide groove.

[0016] In this technical solution, when the baffle needs to be pulled out of the slot, the pull rod can be pulled, and the pull rod will drive the limit block to move away from the baffle. At this time, the spring will be squeezed and contracted until one end of the limit block is completely pulled out of the baffle. Then, the baffle can be pulled upward to pull the baffle out of the slot.

[0017] When the baffle needs to be fixed in the slot, the baffle is inserted into the slot. Then, under the action of the spring rebound force, the spring will push the limit block toward the baffle, so that one end of the limit block will be inserted into the baffle again, thereby fixing the baffle in the slot.

[0018] In the above technical solution, further, one end of the limit block is plugged into the baffle, the pull rod is slidably connected to the U-shaped frame and the slide groove, and the two ends of the spring are tightly welded to the other end of the limit block and the inner wall of the slide groove respectively.

[0019] In this technical solution, it is ensured that one end of the limit block can be inserted into the baffle; it is ensured that the pull rod can operate normally; and it is ensured that the structure of the spring is stable.

[0020] In the above technical solution, further, the driving component includes:

[0021] Two gears, both of which are rotatably mounted on one side of the U-shaped frame, one end of one of the gears passes through one side of the U-shaped frame and is coaxially connected to the roller, an L-shaped plate is fixedly mounted on one side of the U-shaped frame, a motor is fixedly mounted on one side of the L-shaped plate, the output end of the motor passes through one side of the L-shaped plate and is coaxially connected to another gear, and the two gears are meshed.

[0022] In this technical solution, when the motor is started, the output shaft of the motor will drive another gear to rotate. Under the action of meshing, the other gear will drive one of the gears to rotate. Subsequently, one of the gears will drive the roller to rotate, and the roller will drive the cover to rotate. Under the action of the U-shaped frame, the cover will not shake, ensuring that the entire device can work normally.

[0023] In the above technical solution, further, the output shaft of the motor is rotationally connected to the L-shaped plate.

[0024] In this technical solution, it is ensured that the motor can operate normally.

[0025] In the above technical solution, further, a sealing cover is plugged and installed on the top of the feeding shell.

[0026] In this technical solution, under the action of the sealing cover, external impurities can be prevented from entering the placement tank, thereby avoiding affecting the production quality.

[0027] In the above technical solution, further, the three discharge pipes are respectively connected to the three placement slots, and the three discharge pipes are all located directly above the roller feed port, and the output shaft of the motor is rotatably connected to the cavity and one of the placement slots.

[0028] In this technical solution, it is ensured that the NdFeB material in the placement tank can enter the discharge pipe; it is ensured that the NdFeB material in the discharge pipe can enter the drum; and it is ensured that the motor can operate normally.

[0029] The beneficial effects of the utility model are:
