Description

Technical Field

[0001] This utility model relates to the field of blank arrangement technology, specifically to an arrangement device for a square-shaped magnetic core blank. Background Technology

[0002] For U-shaped magnetic core blanks, an inductance test is required after the U-shaped magnetic core blank product is formed. The traditional way of unloading is that after the inductance test, the U-shaped magnetic core blank falls into a collection box through a slide. During the falling process, the U-shaped magnetic core blanks will collide with each other, causing damage and increasing the damage rate of the U-shaped magnetic core blanks. Utility Model Content

[0003] The purpose of this invention is to provide an arrangement device for U-shaped magnetic core blanks. By using a front limiting bar that is threaded through a bolt at the mounting slot, the distance between the front limiting bar and the movable plate can be adjusted to accommodate blanks of different sizes and models, as well as conveyor belts, thereby improving the applicability of the equipment. The conveyor belt collects the U-shaped magnetic core blanks, collecting and limiting a fixed quantity of U-shaped magnetic core blanks during the descent process. The U-shaped magnetic core blanks are then arranged and pushed out in a fixed quantity, reducing damage caused by mutual collisions between the U-shaped magnetic core blanks and reducing the damage rate of the U-shaped magnetic core blanks. This solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an arrangement device for U-shaped magnetic core blanks, including a fixed frame, a conveyor belt inside the fixed frame, a movable plate on one side of the fixed frame, a connecting piece on the side of the movable plate facing the upper end of the conveyor belt, a front limiting strip at the lower end of the connecting piece, and three elongated mounting slots horizontally penetrating inside the connecting piece, with the mounting slots and the front limiting strips fixedly connected by bolts. By adjusting the installation positions of the bolts inside the three mounting slots, blanks of different sizes can be accommodated, adapting to different size application requirements. Simultaneously, during the descent, a fixed quantity of U-shaped magnetic core blanks is collected and limited, reducing damage caused by mutual collisions between the U-shaped magnetic core blanks.

[0005] Preferably, a support plate is provided at the lower end of the movable plate, a pair of sliding bars are provided on the side of the support plate facing the movable plate, and a pair of sliding frames are provided on the side of the movable plate facing the support plate. The inside of the sliding frame is connected to the sliding groove outside the sliding bar. By locking the sliding frame outside the sliding bar, a stable moving trajectory can be provided for the movable plate, improving the efficiency of the equipment during use and avoiding positional deviation when the movable plate moves laterally.

[0006] Preferably, the upper end of the connecting piece is provided with a second cylinder, the lower end of the second cylinder is provided with a transmission groove, and the output shaft of the second cylinder is welded and fixed to the upper end of the movable plate through the transmission groove. The second cylinder and the connecting piece are fixedly connected by bolts. One end of the second cylinder is provided with a first cylinder in a horizontal direction, and the two ends of the first cylinder are welded and fixed to the movable plate and the support plate respectively. The reserved transmission groove facilitates the pushing of the connecting piece, facilitates the longitudinal upward movement of the connecting piece and the front limiting strip, facilitates the reset of the front limiting strip, and reduces the damage rate of the U-shaped magnetic core blank.

[0007] Preferably, guide posts are provided at the four corners of the second cylinder, and the guide posts slide through the connecting piece and are welded and fixed to the upper end of the movable plate. The reserved guide posts can limit the longitudinal movement trajectory of the connecting piece during the longitudinal sliding process, and avoid excessive pressure at the connection position between the second cylinder and the connecting piece when the connecting piece moves longitudinally.

[0008] Preferably, a side limiting strip is provided at one end between the front limiting strip and the movable plate to temporarily block the blanks, and the side limiting strip is welded and fixed to the movable plate. The side limiting strip can restrict the blanks that have been transferred and arranged beforehand. After the number of blanks reaches the arrangement requirement, subsequent pushing can be carried out. The U-shaped magnetic core blanks are collected by the conveyor belt, and the U-shaped magnetic core blanks are arranged and pushed out in a quantitative manner to realize the discharge of batches of U-shaped magnetic core blanks.

[0009] Preferably, a photoelectric sensor is provided at one end of the support plate. The photoelectric sensor is electrically connected to the first cylinder and the second cylinder respectively. After the photoelectric sensor detects the blanks passing through the lower end for a long time, it is considered that the number of blanks has reached the pushing requirement. The photoelectric sensor can give a start signal to the first cylinder and the second cylinder to avoid collisions and compression between the U-shaped magnetic core blanks, and also to avoid the difficulty of arranging too many U-shaped magnetic core blanks.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention uses a front limiting bar, side limiting bar, and movable plate to restrict and arrange the blanks. After a certain number are arranged, a photoelectric sensor detects that blanks are continuously retained at the lower end. The first cylinder pushes the blanks wrapped by the front limiting bar, side limiting bar, and movable plate to be neatly discharged. The second cylinder pushes the front limiting bar to move horizontally in the longitudinal direction. Finally, the movable plate resets to prevent the front limiting bar from colliding with the discharged blanks. Correspondingly, during the blank collection process, the position of the mounting groove can be adjusted by adjusting the position of the bolt in the mounting groove. It can directly adjust and adapt to blanks and conveyor belts of different sizes and models. The conveyor belt collects the U-shaped magnetic core blanks. During the falling process, a certain number of U-shaped magnetic core blanks are collected and restricted. The U-shaped magnetic core blanks are arranged and pushed out in a certain quantity, reducing the damage caused by the collision between the U-shaped magnetic core blanks and reducing the damage rate of the U-shaped magnetic core blanks.

[0018] The present invention will be further described below with reference to specific embodiments.

[0019] like Figure 1 and Figure 3As shown, an arrangement device for a U-shaped magnetic core blank in this embodiment includes a fixed frame 1. The fixed frame 1 is provided with a conveyor belt 2 for transporting the U-shaped magnetic core blank. The U-shaped magnetic core blank can be arranged by the transport of the conveyor belt 2. A movable plate 5 is provided on one side of the fixed frame 1. A connecting piece 7 is provided on the side of the movable plate 5 facing the upper end of the conveyor belt 2. A front limiting strip 9 is provided at the lower end of the connecting piece 7. The U-shaped magnetic core blank can be arranged by the movable plate 5 and the front limiting strip 9. The U-shaped magnetic core blank can be restricted during the arrangement process and subsequently pushed.

[0020] Furthermore, such as Figure 4 As shown, three elongated mounting slots 8 are horizontally arranged inside the connecting piece 7, and the mounting slots 8 are fixedly connected to the front limiting strip 9 by bolts. The mounting position of the lower front limiting strip 9 can be adjusted by the bolts being embedded in different positions inside the mounting slots 8, which can adapt to different sizes of conveyor belts 2 and be suitable for blanks of different widths.

[0021] To facilitate the pushing of the blank placed between the movable plate 5 and the front limiting strip 9, and to actively move the blank away from the conveyor belt 2, a support plate 4 is provided at the lower end of the movable plate 5, such as... Figure 2 As shown, a pair of sliding bars 13 are provided on the side of the support plate 4 facing the movable plate 5, and a pair of sliding frames 14 are provided on the side of the movable plate 5 facing the support plate 4. The interior of the sliding frame 14 is connected to the exterior sliding groove of the sliding bar 13. The sliding groove connection can restrict and support the movement trajectory of the movable plate 5 during the lateral movement of the movable plate 5.

[0022] It is worth mentioning that the support plate 4 and the fixed frame 1 are fixedly connected by bolts. The bolt fixing can improve the integrity of the whole equipment and facilitate installation and disassembly.

[0023] The upper end of the connecting piece 7 is provided with a second cylinder 12, and the lower end of the second cylinder 12 is provided with a transmission groove 16. The output shaft of the second cylinder 12 is welded and fixed to the upper end of the movable plate 5 through the transmission groove 16. The second cylinder 12 and the connecting piece 7 are fixedly connected by bolts. During the extension of the second cylinder 12, the lower connecting piece 7 and the front limiting strip 9 can be directly driven away from the movable plate 5 by the second cylinder 12. Raising the height of the front limiting strip 9 can help to reset the front limiting strip 9 and the movable plate 5.

[0024] To improve the stability of the connecting piece 7 during longitudinal movement, such as Figure 5 As shown, guide posts 6 are provided at the four corners of the second cylinder 12, and the guide posts 6 slide through the connecting piece 7 and are welded and fixed to the upper end of the movable plate 5. When the connecting piece 7 moves longitudinally, the connecting piece 7 slides outside the guide posts 6, and the reserved guide posts 6 can provide a stable vertical movement trajectory.

[0025] To prevent the blank from moving away from the movable plate 5 and the front limiting strip 9 during the transmission process, a side limiting strip 10 is provided at one end between the front limiting strip 9 and the movable plate 5 to temporarily block the blank, and the side limiting strip 10 is welded and fixed to the movable plate 5.

[0026] Furthermore, a photoelectric sensor 15 is provided at one end of the support plate 4. The photoelectric sensor 15 corresponds to the upper surface of the conveyor belt 2 and the edge position between the movable plate 5 and the front limiting strip 9. After the photoelectric sensor 15 detects the blank for a long time, it is considered that the number of blanks has reached the arrangement requirement. A first cylinder 11 is horizontally provided at one end of the second cylinder 12, and the two ends of the first cylinder 11 are welded and fixed to the movable plate 5 and the support plate 4 respectively. The extension of the first cylinder 11 can push and cause the movable plate 5 to move laterally. The photoelectric sensor 15 is connected to the first cylinder 11. The first cylinder 11 and the second cylinder 12 are electrically connected. After the photoelectric sensor 15 detects the first cylinder 11 and the second cylinder 12, the first cylinder 11 and the second cylinder 12 can be started in sequence. Before starting the first cylinder 11 and the second cylinder 12, the photoelectric sensor 15 gives the conveyor belt 2 a stop signal. The conveyor belt collects the U-shaped magnetic core blanks. During the falling process, it collects and restricts a certain amount of U-shaped magnetic core blanks. The U-shaped magnetic core blanks are arranged in a certain quantity and pushed out in a certain quantity, reducing the damage caused by the collision between the U-shaped magnetic core blanks and reducing the damage rate of the U-shaped magnetic core blanks. After the front limiting bar 9 is reset, the conveyor belt 2 is restarted.

[0027] In order to deal with the blanks being transported at the upper end of the conveyor belt 2 and to deflect the offset blanks, both sides of the upper end of the conveyor belt 2 are provided with horizontally arranged deflector plates 3, and the deflector plates 3 are welded and fixed to the upper end of the fixed frame 1.

[0028] Working principle: When using this device to arrange and push out blanks, the blanks that have undergone inductance testing are transported by conveyor belt 2 and aligned by levers 3 (alignment means that the longest side of the blank is parallel to the side of conveyor belt 2; it should be noted that the blanks falling into conveyor belt 2 may not be in a neat order, and the staggered levers 3 only allow aligned blanks to pass through; blanks that are not in an aligned state will adjust their direction to be aligned by the obstruction of levers 3). After alignment, the blanks are blocked by side restraints 10, causing them to remain between the movable plate 5 and the front restraint 9. The photoelectric sensor 15 detects the lower end... When a blank is stuck at a position (the blank does not move), the photoelectric sensor 15 gives a stop signal to the conveyor belt 2. After the conveyor belt 2 stops, the first cylinder 11 drives the movable plate 5 to push forward and push the arranged blanks from the conveyor belt 2 onto the platform (in the actual scenario, the side of the conveyor belt 2 has a platform that is flush with the height of the conveyor belt 2, which is not shown in the figure). The second cylinder 12, with the extension of the piston rod, uses the lifting action to lift the connecting piece 7 together with the front limiting strip 9 upward. The first cylinder 11 retracts to reset the whole, and the second cylinder 12 extends again to reset the connecting piece 7 together with the front limiting strip 9 downward to the initial state, and the conveyor belt 2 is started to continue the arrangement operation.
