Description

Technical Field

[0001] This utility model relates to the technical field of electrical component processing equipment, specifically to a batch feeding device for inductor sheets. Background Technology

[0002] As an electrical component, an inductor is a passive electronic component that stores electrical energy in the form of a magnetic field. Its core characteristic is its resistance to changes in current. One step in the manufacturing process of an inductor is the pressing of powder. This requires precisely placing the unpressed sheet into the cavity of a mold, where it is automatically pressed into shape by a pressing device. The finished sheet is then safely removed from the mold. Currently, there are generally two methods for unloading the pressed sheet: one is manual removal from the mold, which poses safety hazards and is inefficient; the other is using a robotic arm to replace manual removal, achieving mechanized unloading and reducing costs. There are safety hazards, but currently, simple robotic arms can only achieve point-to-point transfer of materials. Direct stacking by robotic arms can easily cause damage to the materials due to collisions and pressure between them. Therefore, currently, the materials are removed from the mold by robotic arms and placed in designated positions, and then manually placed into the frames. This method does not effectively improve efficiency. Workers still need to stay in the equipment's discharge area for a long time to manually complete the unloading and stacking of materials. When the frames are full, the full frames need to be placed back and replaced with empty frames to continue stacking materials. If the workers' movements are too slow during this process, the materials may accumulate in the designated positions, which can easily damage the materials.

[0003] Therefore, there is an urgent need for a specialized discharge device that can automate, batch process, and orderly transfer the fragile inductive sheets after pressing and molding. Utility Model Content

[0004] The purpose of this invention is to provide a batch feeding device for inductor sheets, which aims to solve the problems mentioned above and cooperate with a robotic arm to achieve batch feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a batch feeding device for inductor sheets, comprising a gripping mechanism, a conveying mechanism, and two lifting mechanisms. The conveying mechanism has a loading station in the middle, and the gripping mechanism is located above the loading station. The two lifting mechanisms are symmetrically distributed on both sides of the conveying mechanism with the loading station as the center. Each of the two lifting mechanisms includes a vertical slide rail and a sliding frame. The sliding frame is slidably connected to the vertical slide rail and has multiple frame plates arranged along the sliding direction. One lifting mechanism is used to place the frame plates one by one onto the conveying mechanism, and the other lifting mechanism is used to lift the frame plates onto the conveying mechanism. The conveying mechanism is used to transport the frame plates back and forth between the two lifting mechanisms. When the frame plate passes through the middle of the conveying mechanism, the gripping mechanism places the sheet on the frame plate.

[0006] Optionally, the conveying mechanism comprises multiple conveying sections, with accommodating grooves between adjacent conveying sections, and the upper surfaces of the multiple conveying sections are flush.

[0007] Optionally, the sliding frame is provided with a plurality of fork plates for placing frame plates at intervals from top to bottom, and the fork plates correspond to receiving slots.

[0008] Optionally, one end of the fork plate is connected to the sliding frame, and the top of the other end is provided with a stop block, the distance between the sliding frame and the stop block being equal to the width of the frame plate.

[0009] Optionally, the conveying mechanism is provided with a limit plate at one end and a baffle plate at the other end.

[0010] Optionally, the conveying mechanism includes a sensor switch disposed in the middle, the sensor switch being electrically connected to the gripping mechanism.

[0011] Optionally, the gripping mechanism includes a horizontal slide rail, a cylinder, and a gripping assembly. The horizontal slide rail is perpendicular to the conveying mechanism. One end of the horizontal slide rail is located above the middle of the conveying mechanism, and the other end is located above a designated position. The cylinder is slidably connected to the horizontal slide rail, and the output end of the bottom of the cylinder is connected to the gripping assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The present invention provides a batch feeding device for inductor sheets. Through the cooperation of a gripping mechanism, a conveying mechanism and a lifting mechanism, one lifting mechanism lowers the empty frame plate step by step to the conveying mechanism, so that the frame plate moves with the conveying mechanism towards another lifting mechanism. After the robot completes the sheet transfer, the gripping mechanism grabs the sheet from the designated position and delivers it to the frame plate at the loading station. The gripping mechanism and the conveying mechanism realize the continuous automatic transfer of the sheet and stack the sheet on the frame plate. The frame plate full of sheet is lifted by another lifting mechanism to the conveying mechanism for temporary storage, realizing automated and batch feeding. Attached Figure Description

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0024] like Figure 1-5As shown, a batch feeding device for inductor sheets includes a gripping mechanism 1, a conveying mechanism 2, and two lifting mechanisms 3. The middle part of the conveying mechanism 2 is a loading station. The gripping mechanism 1 is located above the loading station in the middle of the conveying mechanism 2. The two lifting mechanisms 3 are symmetrically distributed on both sides of the conveying mechanism 2 with the loading station as the center. Each lifting mechanism 3 includes a vertical slide rail 31 and a sliding frame 32. The sliding frame 32 is slidably connected to the vertical slide rail 31 and has multiple frame plates 4 arranged along the sliding direction. One lifting mechanism 3 is used to place the frame plates 4 one by one onto the conveying mechanism 2, and the other lifting mechanism 3 is used to lift the frame plates 4 onto the conveying mechanism 2. The conveying mechanism 2 is used to transport the frame plates 4 back and forth between the two lifting mechanisms 3. When the frame plate 4 passes through the middle of the conveying mechanism 2, the gripping mechanism 1 places the sheet on the frame plate 4.

[0025] In the existing technology, simple robotic arms can only transfer the material sheet between two points: the mold and the designated position. Although there are also robotic arms that can achieve multi-axis movement and can stack the material sheet in the frame plate 4 after programming, high-precision multi-axis robotic arms are expensive to purchase and use, and the programming is complicated. They also require a highly stable frame plate 4 to be placed in the designated position. After the robotic arm completes the stacking of the material sheet in the frame plate 4, a new frame plate 4 still needs to be replaced manually.

[0026] Compared with the prior art, the batch feeding device for inductor sheets provided by this utility model, through the cooperation of gripping mechanism 1, conveying mechanism 2 and lifting mechanism 3, allows one lifting mechanism 3 to lower empty frame plates 4 step by step to conveying mechanism 2, so that frame plates 4 move with conveying mechanism 2 towards another lifting mechanism 3. After the robot completes the sheet transfer, gripping mechanism 1 grabs the sheet from the designated position and delivers it to the frame plate 4 at the loading station. The gripping mechanism 1 and conveying mechanism 2 realize the continuous automatic transfer of sheet and stack the sheet on the frame plate 4. The frame plate 4 with full sheet is lifted by another lifting mechanism 3 to conveying mechanism 2 for temporary storage. By lowering the frame plate 4 through one lifting mechanism 3 and lifting the frame plate 4 through another lifting mechanism 3, the frame plate 4 is loaded sequentially, realizing automated and batch feeding. Moreover, the conveying mechanism 2 is set up in a reasonable horizontal space and the lifting mechanism 3 is set up in a reasonable vertical space, and the two are combined with each other, resulting in a reasonable layout and saving space.

[0027] In some embodiments, the conveying mechanism 2 comprises a plurality of conveying sections 21, with accommodating grooves 200 between adjacent conveying sections 21, and the upper surfaces of the plurality of conveying sections 21 are flush, such as... Figure 2-3The conveying mechanism 2 specifically consists of a main frame and a conveyor belt. The main frame has multiple recesses on its upper side, and the conveyor belt wraps around the outside of the main frame. The conveyor belt is driven by a drive device to ensure that the multiple conveying sections 21 maintain the same speed. Furthermore, each conveying section 21 remains flush. The length of the frame plate 4 is greater than the total length of the two conveying sections 21 and the receiving groove 200, allowing the frame plate 4 to pass smoothly. Based on this, the sliding frame 32 is provided with multiple fork plates 300 spaced from top to bottom for placing the frame plate 4. The fork plates 300 correspond to the receiving groove 200, which is mainly designed to accommodate the fork plates 300. When the sliding frame 32 slides down, the fork plates 300 enter the receiving groove 200, allowing the frame plate 4 on the fork plate 300 to fall naturally onto the conveying section 21 without affecting the conveying of the frame plate 4 by the conveying section 21.

[0028] In some embodiments, one end of the fork plate 300 is connected to the sliding frame 32, and the top of the other end is provided with a stop block 330. The sliding frame 32 and the stop block 330 are used to block the frame plate 4, ensuring that the frame plate 4 is stably placed on the fork plate 300. At the same time, the distance between the sliding frame 32 and the stop block 330 is equal to the width of the frame plate 4, so that the frame plate 4 will not move along its width, ensuring that the frame plate 4 can fall smoothly onto the conveying section 21.

[0029] In some embodiments, the conveying mechanism 2 is provided with a limiting plate 22 at one end and a baffle plate 23 at the other end. The limiting plates 22 are arranged vertically, and the side facing the baffle plate 23 is flat. One side of the frame plate 4 on the lifting mechanism 3 is in contact with the limiting plate 22. The frame plate 4 is positioned in conjunction with the sliding frame 32 and the stop block 330. After the worker places the frame plate 4 on the lifting mechanism 3, he pushes the frame plate 4 so that one side of it abuts against the limiting plate 22. The sliding frame 32 slides vertically along the vertical slide rail 31, so that when the frame plate 4 is lowered normally, it can accurately fall to the starting point of one end of the conveying mechanism 2.

[0030] In some embodiments, the middle part of the conveying mechanism 2 is a loading station. The conveying mechanism 2 includes a sensor switch 24 disposed in the middle part. The sensor switch 24 is electrically connected to the gripping mechanism 1. The sensor switch 24 can be a background suppression photoelectric sensor. At the same time, multiple sensor switches 24 are preferably arranged to detect the frame plate 4 passing on the conveying mechanism 2, so as to ensure that the gripping mechanism 1 and the conveying mechanism 2 cooperate with each other to realize the stacking of material pieces on the frame plate 4 while the frame plate 4 moves.

[0031] In some embodiments, the gripping mechanism 1 includes a horizontal slide rail 11, a cylinder 12, and a gripping assembly 13. The horizontal slide rail 11 is perpendicular to the conveying mechanism 2. One end of the horizontal slide rail 11 is located above the middle of the conveying mechanism 2, and the other end is located above a designated position. In existing mechanisms, a positioning structure for positioning the material sheet is set at the designated position. After the robot places the material sheet at the designated position, the material sheet will not be displaced. The cylinder 12 is slidably connected to the horizontal slide rail 11, and the output end of the bottom of the cylinder 12 is connected to the gripping assembly 13. The cylinder 12 can drive the gripping assembly 13 to move up and down. The cylinder 12 can be an existing sliding cylinder 12, telescopic cylinder 12, or other cylinders that can drive the gripping assembly 13 to move up and down. The gripping assembly 13 can be a gripper actuator or a vacuum suction cup with an existing structure.

[0032] Working principle: One lifting mechanism 3 slides upward, placing all fork plates 300 above and filling the frame plate 4. The other lifting mechanism 3 slides downward, placing all fork plates 300 in the corresponding receiving slots 200. The sliding frame 32 of one lifting mechanism 3 slides down until the bottom frame plate 4 falls onto the conveying mechanism 2, and the corresponding fork plates 300 enter the receiving slots 200. At this time, the conveying mechanism 2 starts to transport the frame plate 4. When the sensor switch 24 detects the frame plate 4, the conveying mechanism 2 stops, and the gripping component 13 grips the material sheet from the designated position. The cylinder 12 drives the gripping component 13 to descend, gripping the pressed inductor material sheet. Then, the lifting cylinder 12 moves horizontally to directly above the paused frame plate 4, and the descending cylinder 12 places the material sheet into the frame plate 4. When the frame plate 4 is full of material sheets corresponding to the position of the gripping component 13, the conveying mechanism 2 continues to move forward, expanding the space of the frame plate 4 full of material sheets. The conveyor 2 moves forward until the empty space of the frame plate 4 is directly opposite the gripping component 13. It should be noted that the position corresponding to the gripping component 13 is the loading station, which is also the detection position of the sensor switch 24. When the sensor switch 24 detects that there is a piece of material within the detection range, it starts the conveyor 2 to move forward until the empty space of the frame plate 4 is directly opposite the sensor switch 24. The gripping mechanism 1 continues to stack pieces of material onto the frame plate 4 until the frame plate 4 is fully loaded, that is, after the frame plate 4 passes the loading station. The conveyor 2 continues to start and transport the frame plate 4 loaded with pieces of material to the position blocked by the baffle plate 23. At this time, another lifting mechanism 3 slides the sliding frame 32, and the fork plate 300 at the top lifts the frame plate 4 onto the conveyor 2. The other lifting mechanism 3 continues to slide down and lower the second frame plate 4 onto the conveyor 2. This process is repeated to form an automated closed loop of "one lifting mechanism 3 supplies empty frame plates 4, stacks pieces in the middle, and collects fully loaded frame plates 4 on the right side".

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
