Description

Technical Field

[0001] This application relates to the field of pad printing detection equipment, and particularly to a pad printing detection equipment for fuse cores. Background Art

[0002] A fuse core is a device used for overcurrent protection, usually used in circuits to prevent equipment damage or fire caused by excessive current. When the current in the circuit exceeds the set value, the fuse core will melt, thus cutting off the circuit and protecting electrical equipment. The fuse core is usually made of a fusible alloy with a relatively low melting point so as to melt quickly when the current is excessive; after the production of the fuse core, a pad printing operation is required, that is, product models, product parameters, national standards, etc. are printed on the fuse core.

[0003] Currently, the patent with publication number CN204375667U discloses a fuse core automatic assembly machine, including a frame, a workbench, an assembly part and a pad printing part both arranged on the frame, and the assembly part and the pad printing part are connected by a manipulator mechanism; this application has improved work efficiency and the automation level of the equipment.

[0004] During the production process of the fuse core, quartz sand needs to be filled, and some quartz sand will adhere to the surface of the fuse core. When the quartz sand adhering to the surface of the fuse core is in the pad printing position, it causes the pad printing to not fully fit the surface of the fuse core, and the pad printing is likely to detach from the fuse core during transportation, resulting in the fuse core being unable to be normally identified. Summary of the Invention

[0005] In order to reduce the adhesion of quartz sand on the surface of the fuse core during pad printing, this application provides a pad printing detection equipment for fuse cores.

[0006] A pad printing detection equipment for fuse cores provided by this application adopts the following technical solutions:

[0007] A pad printing detection equipment for fuse cores includes a frame, a pad printing component, a sand blowing component and a conveying component. The pad printing component and the sand blowing component are both arranged on the frame. The conveying component is used to move the fuse core body in the direction from the sand blowing component to the pad printing component. The sand blowing component includes a sand blowing cover, a sand blowing cylinder, a gas source, a gas supply pipe and a collecting piece. The sand blowing cylinder is arranged on the frame. The sand blowing cover is arranged on the piston rod of the sand blowing cylinder. The sand blowing cover is used to cover the fuse core body. The gas source is arranged on the frame. One end of the gas supply pipe is arranged on the gas source, and the other end of the gas supply pipe is arranged on the sand blowing cover. The collecting piece is used to collect the quartz sand separated from the fuse core body.

[0008] By adopting the above technical solution, the sand-blowing assembly is used to separate the quartz sand adhered to the core body from the core body. Before entering the pad printing assembly, the conveying assembly first sends the core body to the station where the sand-blowing assembly is located. The piston rod of the sand-blowing cylinder drives the sand-blowing hood to move until the sand-blowing hood covers the core body. The air source supplies air, and the air from the air source enters the sand-blowing hood through the air supply pipe. The air flow speed in the sand-blowing hood is increased, and the quartz sand adhered to the core body is blown off. The blown-off quartz sand enters the collecting member, reducing the re-contact of the quartz sand with the core body. After the sand-blowing operation is completed, the piston rod of the sand-blowing cylinder resets, and the sand-blowing hood moves away from the core body. Driven by the conveying assembly, the core body is moved to the pad printing assembly for pad printing operation, so that the pad printing is completed and fits the core body. The pad printing quality of the core body is improved by the sand-blowing assembly.

[0009] Optionally, a feeding assembly is further arranged on one side of the frame. The feeding assembly includes a feeding frame, a storage box, a conveyor belt, a translation member, an air pipe, an air pump, a placing table and a clamping member. The storage box is located on one side of the frame and is arranged on the feeding frame. The feeding frame is used to store the core body. The conveyor belt is used to sequentially transport the core body out of the storage box. The translation member is used to separate the core body from the conveyor belt. The placing table is arranged on the frame. One end of the air pipe is arranged on the feeding frame, and the other end of the air pipe is arranged on the placing table. The air pump is used to transport the core body on the translation member to the placing table through the air pipe. The clamping member is used to place the core body on the placing table onto the conveying assembly. A vibrator for vibrating the core body is arranged on the placing table.

[0010] By adopting the above technical solution, the feeding assembly is used to sequentially send the core body onto the conveying assembly, so that the core bodies on the conveying assembly are arranged at intervals; the storage box is used to store the core bodies that have not been pad printed and labeled. The conveyor belt sequentially sends out the core bodies in the storage box. The translation member sequentially sends the core bodies on the conveyor belt to the position of the air pipe. The air pump is started to change the air around the core body on the translation member and send the core body into the air pipe. The core body is moved to the placing table through the air pipe. The clamping member sequentially clamps the core bodies onto the conveying assembly. The sequential feeding operation of the core body is realized through the feeding assembly, and the relative position adjustment between the feeding frame and the frame can be realized through the air pipe, which can adapt to the space of different factories and has a more reasonable structure; the vibrator is used to vibrate the core body to detect the presence of welding defects and false welding in the core body.

[0011] Optionally, the translation member includes a translation block, a translation cylinder and a cover plate. The translation block is slidably connected to the feed rack along a movement direction perpendicular to the core body on the transmission belt. The translation block is provided with a receiving groove for accommodating the core body. The translation cylinder is used to drive the translation block to move. The cover plate is arranged on the feed rack. When the air pump drives the core body to move toward the air pipe, the cover plate and the receiving groove limit the movement direction of the core body.

[0012] By adopting the above technical solution, the fusible core body on the transmission belt moves to the receiving groove of the translation block, the piston rod of the translation cylinder moves, and the translation block moves, so that the fusible core body is located between the air pump and the air pipe, and the fusible core body is aligned with the air pipe. The cover plate is arranged on the feed rack, and the cover plate and the receiving groove limit the rolling of the fusible core body in the horizontal direction. When the air pump is working, the air pump sends the fusible core body into the air pipe and moves it to the placement table through the air pipe.

[0013] Optionally, a detection component is also provided on the frame, and the detection component is located on the side of the sand blasting component away from the pad printing component. The detection component includes a resistance detection component, and the resistance detection component includes a resistance detector, two double-headed cylinders and a driving cylinder.

[0014] By adopting the above technical scheme, the parameters of the fuse body include rated voltage, rated current, etc. The rated voltage and rated current of the fuse body can be tested by the resistance detection component to see whether they meet the standards. The fuse body on the conveying assembly is first moved to the station where the resistance detection component is located, and the driving cylinder drives the double-headed cylinder to move toward the fuse body. The piston rod of the double-headed cylinder contracts, and the four clamping claws on the two double-headed cylinders clamp the two ends of the fuse body respectively. Then, a constant current is applied through the resistance detector, and the resistance value of the fuse body can be obtained by measuring the voltage change. After the test is completed, the resistance detector is turned off and the clamping claws of the double-headed cylinder release the fuse body, and the driving cylinder drives the double-headed cylinder to reset.

[0016] By adopting the above technical solution, the fuse core body includes end caps and a tube body. Quartz sand is stored in the tube body, and the end caps are sleeved on both ends of the tube body. By measuring the length of the fuse core body, it can be known whether the end caps are installed in place. When the fuse core body that has completed the resistance test moves to the station of the length detection component, the detection cylinder is activated, and the pressing block is pressed tightly on the fuse core body to restrict the movement of the fuse core body relative to the conveying component.

The distribution direction of the plurality of jacking blocks is parallel to the distribution direction from the pad printing component to the sand blowing component. A limiting groove is formed in the jacking block.

[0018] By adopting the above technical solution, the conveying component is used to move the fuse core body on the machine frame. The fuse core body is placed on the conveying frame. When the fuse core body needs to move to the next station, the lifting motor drives the lifting rod to rotate, and the lifting rod drives the lifting frame to move in the vertically upward direction. At this time, the fuse core body is clamped in the limiting groove of the jacking block. At this time, the moving cylinder is driven, and the piston rod of the moving cylinder drives the moving frame to move. The moving frame drives the jacking block to move, so that the fuse core body on the jacking block moves to the next station. At this time, the lifting motor still drives the lifting rod to rotate, and the lifting rod drives the lifting frame to move in the vertically downward direction. The fuse core body is placed on the conveying frame again for subsequent movement to the next station.

[0019] Optionally, the pad printing assembly includes a pad printing machine body, a CCD body, and a pushing member. The pad printing machine body is disposed on the frame. The CCD body is located on one side of the conveying frame. The conveying frame includes a fixed frame and a pushing frame. The fixed frame is disposed on the frame.

The pushing rod can drive the pushing block to move. The pushing block drives the pushing frame to move. The fuse core body on the pushing frame moves to the CCD body station. The CCD body inspects the pad printing operation on the fuse core body. After the inspection is completed, the pushing motor drives the pushing disc to rotate. The pushing disc drives the pushing rod to rotate eccentrically. The pushing rod drives the pushing block to move. The pushing frame resets again. The fuse core body on the pushing frame can be jacked up by the jacking block again and moved to the next station. The CCD body is used for the pad printing inspection of the fuse core, improving the pad printing quality of the fuse core.

[0021] Optionally, a waste recycling assembly is further disposed on the frame. The waste recycling assembly includes a waste clamping member, a first pipe, a second pipe, a third pipe, three sorting boxes, and a sorting member. The first pipe is disposed on the frame.

When the quality of the molten core body is lower than the standard, the flip scale sends the molten core body to the recycling box. When the quality of the molten core body meets the standard, the flip scale sends the molten core body to the drying transmission component.

[0026] By adopting the above technical scheme, the weighing piece is used to weigh the weight of the fuse body. The inside of the fuse body is filled with quartz sand. The filling quality of the quartz sand affects the quality of the fuse. The weight of the fuse body can reflect whether the quartz sand is filled in place. The fuse body is moved to the flip scale through the transmission component. The weighing machine body can measure the weight of the fuse body on the flip scale. When the weight of the fuse body meets the requirements, the flip motor drives the flip scale to flip, and the fuse body is moved to the drying transmission part for drying. When the weight of the fuse body does not meet the requirements, the flip motor drives the flip scale to flip in the opposite direction, and the flip scale drives the fuse body into the recycling box for subsequent reuse. The weighing component is used to weigh the fuse body to further improve the factory quality of the fuse body.
