Description
Technical Field
[0001] The utility model relates to the technical field related to transformer group detection, in particular to a grabbing component for transformer group appearance detection. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.; according to its use, it can be divided into: power transformers and special transformers (electric furnace transformer, rectifier transformer, industrial frequency test transformer, voltage regulator, mining transformer, audio transformer, medium frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, mutual inductor, etc.).
[0003] Small transformers refer to power transformers and audio transformers below 2kVA. Small transformers need to be inspected for appearance after production. The existing transformer appearance inspection method is that the staff puts the transformers one by one on the inspection device for inspection, and then takes them down and arranges them after the inspection. The work efficiency of this pick-and-place method is very low.
[0004] In summary, there is a need for a grabbing assembly for transformer group appearance inspection that can improve the efficiency of picking and placing. Utility Model Content
[0005] The utility model aims to overcome the disadvantage that the transformer appearance detection method in the prior art is that the staff puts the transformers one by one on the detection device for detection, takes them down and arranges them after the detection is completed, and the working efficiency of this pick-and-place method is very low. A grabbing component for transformer group appearance detection is provided, which can improve the pick-and-place efficiency.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A grabbing assembly for transformer group appearance inspection comprises a placing table and a suction table, wherein a chamber is provided inside the suction table, a magnet is provided inside the chamber, the magnet and the chamber are movably connected, one side of the suction table is a grabbing surface, a driving structure connected to the magnet is installed on the other side of the suction table, and a transformer placing groove matching one side of the suction table is provided on the placing table.
[0008] In the natural state, the magnet in the chamber is on the side close to one of the sides (grabbing surface) of the suction table. When grabbing, first place the transformers to be tested in the transformer placement slot one by one and arrange them, then use one of the sides of the suction table to approach the transformer group on the transformer placement slot, so that the transformer on the transformer placement slot is adsorbed on one of the sides of the suction table under the action of magnetic force; when putting it down, the staff operates the driving structure to move the magnet in the chamber from the side close to one of the sides (grabbing surface) of the suction table to the side away from one of the sides (grabbing surface) of the suction table. At this time, since the distance between the magnet and the transformer is pulled away, the magnetic force between the two is weakened, so the transformer group on the suction table will automatically fall onto the appearance inspection device under the action of gravity. The structure is simple, the operation is convenient, and the pick-and-place efficiency is high.
[0009] Preferably, the driving structure includes a push plate located outside the suction table, the push plate and the magnet are fixedly connected by a movable connecting rod, a connecting through hole matching the movable connecting rod is provided on the other side of the suction table, and the movable connecting rod is placed in the connecting through hole and slidably connected thereto. Since the push plate, the movable connecting rod and the magnet are fixedly connected, the staff can push the push plate by grabbing it, thereby driving the magnet in the chamber to move, so that it approaches or moves away from one side (grasping surface) of the suction table, and the structure is simple and easy to operate.
[0010] Preferably, a handle is provided on the other side of the suction table, and the handle and the suction table are fixedly connected by a fixed connecting rod. The handle, the fixed connecting rod and the suction table are fixedly connected, and the design of the handle makes it convenient for the staff to hold the suction table.
[0011] Preferably, the push plate is placed between the handle and the suction table, the fixed connecting rod and the movable connecting rod are parallel to each other, the push plate is provided with a guide through hole matching the fixed connecting rod, the fixed connecting rod is placed in the guide through hole and the two are slidably connected. The matching design of the guide through hole and the fixed connecting rod facilitates the installation and positioning of the push plate on the one hand, and guides the movement of the push plate and the magnet on the other hand, thereby improving the movement accuracy.
[0012] Preferably, a sliding bearing is installed at the guide through hole, and the push plate is slidably connected to the fixed connecting rod through the sliding bearing. The push plate and the fixed connecting rod are connected through the sliding bearing, so that the relative movement between the two is smoother, the friction and wear between the two are reduced, the energy loss of the transmission system is reduced, the transmission efficiency is improved, and the noise generated during movement can also be reduced.
[0013] Preferably, a reset spring is provided between the push plate and the handle, and the reset spring is sleeved on the fixed connecting rod, one end of the reset spring is connected to the push plate, and the other end of the reset spring is connected to the handle. In the natural state, the magnet in the chamber is pressed against the side close to one side (grasping surface) of the suction table under the preload force of the reset spring. When the transformer group needs to be put down, the staff will hold the handle and the push plate together in their hands. When the hand is tightened, the push plate can be driven to move in the direction of the handle, and at the same time, the magnet in the chamber is driven from the side close to one side (grasping surface) of the suction table to the side away from one side (grasping surface) of the suction table. At this time, due to the distance between the magnet and the transformer being pulled away, the magnetic force between the two is weakened, so the transformer group on the suction table will automatically fall to the appearance detection device under the action of gravity; when the hand is released, the push plate and the magnet can be automatically reset under the elastic force of the reset spring. The structure is simple, the operation is convenient, and the efficiency of picking and placing is high.
[0014] The utility model has the following beneficial effects: simple structure, convenient operation, high efficiency of taking and placing, convenient installation, improved movement accuracy, reduced friction and wear, and reduced noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The driving structure includes a push plate 6 located outside the suction table 2. The push plate 6 and the magnet 4 are fixedly connected by a movable connecting rod 7. A connecting through hole 8 matching the movable connecting rod 7 is provided on the other side of the suction table 2. The movable connecting rod 7 is placed in the connecting through hole 8 and is slidably connected thereto.
[0022] A handle 9 is also provided on the other side of the suction platform 2 , and the handle 9 and the suction platform 2 are fixedly connected via a fixed connecting rod 10 .
[0023] The push plate 6 is placed between the handle 9 and the suction platform 2. The fixed connecting rod 10 and the movable connecting rod 7 are parallel to each other. A guide hole 11 matching the fixed connecting rod 10 is provided on the push plate 6. The fixed connecting rod 10 is placed in the guide hole 11 and the two are slidably connected.
[0024] A sliding bearing 12 is installed at the guide through hole 11 , and the push plate 6 is slidably connected to the fixed connecting rod 10 via the sliding bearing 12 .
[0025] A return spring 13 is provided between the push plate 6 and the handle 9 . The return spring 13 is sleeved on the fixed connecting rod 10 . One end of the return spring 13 is connected to the push plate 6 , and the other end of the return spring 13 is connected to the handle 9 .
