Description

Technical Field

[0001] The invention relates to a detection device for automatic detection and stacking of iron cores, belonging to the technical field of mechanical detection equipment. Background Art

[0002] Under the existing technology, the iron core is the main magnetic circuit part of electrical appliances such as motors, transformers, and mutual inductors. The iron cores with different magnetic properties determine the performance of different products, so there are strict inspection requirements for different types of iron cores.

[0003] At present, manual feeding is more commonly used, in which operators place a small amount of iron cores on the assembly line at a time, and classify them after inspection. During classification, a blowing device is installed on the corresponding inspection position to blow the inspected iron cores into the receiving frame, and finally the operators organize and store them. In the above-mentioned single assembly line transportation method, since the joints between the units are fixed bell mouths, if too many iron cores are placed at one time when the iron cores are heavy, the feeding port will be blocked. Therefore, the number of iron cores sent for inspection in a single batch is limited, and it is necessary to manually put the iron cores into the feeding assembly line continuously, which slows down the production rhythm.

[0004] For example, a Chinese patent with the patent publication number CN212284943U discloses an automatic core detection device, which includes an automatic core feeding unit and a detection and sorting unit, which cooperate with each other; the detection and sorting unit includes a support base and a rotatable disc detection table arranged above the support base, and the rotatable disc detection table is evenly distributed with a number of feeding stations with empty slots at the bottom, and on the support base, corresponding to the feeding stations, a feeding photoelectric sensing mechanism, a detection mechanism and a number of sorting mechanisms are arranged in sequence. The utility model has an ingenious structure, and the cores are fed into the feeding trough in order, which is convenient and quick to use and avoids material accumulation; the cores enter the detection and sorting unit through the feeding trough, and then the cores can be identified according to the quality grade, and then enter the sorting mechanism behind to be sorted according to the grade.

[0005] The above patented automatic core detection device has high detection efficiency, accurate sorting, high degree of automation and strong practicality; however, it will cause collisions between cores during operation. Since collisions between cores will cause magnetic changes, there is a certain risk, which may change the performance of the product and have a serious impact on subsequent processes; and the cores entering the receiving frame of the device still need to be reorganized by the operator, which consumes manpower.

[0006] Therefore, in order to solve the above-mentioned background problems, it is urgent to develop a detection device for automatic detection and stacking of iron cores. Summary of the invention

[0050] The present invention is described below in conjunction with the accompanying drawings and specific embodiments:

[0051] like Figures 1 to 8 As shown, a detection device for automatic detection and stacking of iron cores includes a feeding unit, a detection unit and a stacking unit;

[0052] The feeding unit includes a front-end feeding line 1, an adjusting feeding line 2 and a feeding docking small line 3, and a connecting plate 4 is provided between every two lines;

[0053] The detection unit includes a turntable mechanism 7, and the turntable mechanism 7 is docked with the feeding docking small assembly line 3.

[0054] In this embodiment, the conveying structure of the present invention is composed of three assembly lines, and every two assembly lines are directly provided with connecting plates.

[0055] In this embodiment, the feeding and docking small assembly line 3 is arranged on the first supporting cabinet 6 ; the second supporting cabinet 11 is arranged on one side of the iron core detection mechanism 8 .

[0056] like Figure 3 As shown, in order to adjust the auxiliary feeding mechanism 5 on the feeding assembly line 2, the auxiliary feeding mechanism 5 is arranged at the discharge end of the feeding assembly line 2, and the auxiliary feeding mechanism 5 includes a motor 5.1 and a belt 5.2 driven by the motor 5.1; the belt 5.2 is arranged vertically, and a bakelite board 5.3 with a trumpet-shaped opening is arranged on the other side; the bakelite board 5.3 is arranged at the front end of the feeding assembly line 2, and is arranged in a trumpet shape, and the opening size of the trumpet can be manually adjusted according to the different shapes of the iron cores. At the same time, under the action of the lateral friction force provided by the belt 5.2, the auxiliary feeding mechanism 5 will send the iron cores to be inspected into the feeding docking small assembly line 3 one by one in turn, and enter the turntable mechanism 7 through the feeding docking small assembly line 3.

[0057] like Figure 2The figure shows the specific docking structure of the feeding docking small assembly line and the turntable mechanism, the turntable mechanism 7 includes a turntable body 7.1, the outermost side of the turntable body 7.1 is provided with a detection groove 7.3, the inner diameter of the detection groove 7.3 is larger than the iron core; a connecting outer plate 7.2 is arranged around the outer periphery of the turntable body 7.1; the feeding docking small assembly line 3 includes a small assembly line 3.1 and a feeding plate 3.2; the connecting outer plate 7.2 of the turntable mechanism 7 is docked with the feeding plate 3.2 of the feeding docking small assembly line 3.

[0058] like Figure 1 As shown, in this embodiment, the turntable mechanism 7 is provided with an inspection station, a material receiving station and a palletizing station along the circumferential direction; the inspection station is provided with an iron core inspection mechanism 8, the material receiving station is provided with a material receiving device 9, and the palletizing station is provided with a palletizing device 10.

[0059] In this embodiment, according to the weight of a single iron core and the number of single flows, after multiple tests, it was determined that the connecting plate 4 was made of 3MM stainless steel, which was locked on the assembly line bracket with screws to connect the front and rear assembly lines. The assembly lines are all built with aluminum profiles, with conveyor belts installed on them, and the motors are controlled by PLC to make them run; and a photoelectric sensor is set at the end of each assembly line.

[0060] When the equipment starts running, the assembly line starts running, and the operator needs to place the iron core to be tested on the front-end feeding assembly line 1. When the iron core flows through the photoelectric sensor at the end of the front-end feeding assembly line 1, the PLC connected to it starts timing. After a period of timing, the PLC controls the front-end feeding assembly line 1 to stop moving, until the photoelectric sensor at the end of the feeding assembly line 2 is adjusted to not sense the iron core, and the PLC resumes the front-end feeding assembly line 1 to continue moving. This limits the number of iron cores sent for inspection in a single batch to prevent the feed port from being blocked by too many iron cores sent for inspection.

[0061] like Figure 4 The figure shows a schematic diagram of the structure of the core detection mechanism of the present invention, wherein the core detection mechanism 8 comprises a detection bracket 8.2, on which a detection cylinder 8.3 is arranged, and a POM rod 8.4 is connected to the bottom of the detection cylinder 8.3; a special-shaped copper block for detecting the core is arranged at the bottom end of the POM rod 8.4; and the turntable body 7.1 is arranged on the cam divider 8.1.

[0062] like Figure 5 The figure shows a specific structural schematic diagram of the special-shaped copper block, which includes a first upper special-shaped copper block 8.5, a first lower special-shaped copper block 8.6, a second upper special-shaped copper block 8.7 and a second lower special-shaped copper block 8.8; the special-shaped copper blocks are connected to the iron core detector 12 in the second support cabinet 11 through wires.

[0063] In this embodiment, the turntable can be made of bakelite material, and divided into 8 areas according to the process requirements of the iron core detection. Grooves are dug at the outermost edges of different areas, and the grooves are slightly larger than the size of an iron core. The middle of the groove is hollowed out for the detection mechanism to descend. The turntable body 7.1 is controlled by a cam divider 8.1;

[0064] After the iron core flows into the detection tank 7.3 through the feeding docking small assembly line 3, the photoelectric sensor installed above the detection tank 7.3 transmits a signal to the PLC. The command issued by the PLC rotates the cam divider 8.1, so that the turntable body 7.1 rotates through a fixed angle (one angle is one workstation, and since the turntable body 7.1 is locked on the cam divider 8.1, it rotates through the same angle).

[0065] In this embodiment, the core detection mechanism 8 mainly tests the voltage through current and makes judgments and classifications based on the voltage. When the detection cylinder 8.3 pushes the POM rod 8.4 to pass through the core to be detected and reaches the limit position, it sends a signal to the PLC. The PLC sends an instruction to clamp the special-shaped copper block on the POM rod 8.4 with a clamping cylinder equipped with a special-shaped copper block at its lower end. The upper and lower groups of special-shaped copper blocks are respectively the first upper special-shaped copper block 8.5, the first lower special-shaped copper block 8.6, the second upper special-shaped copper block 8.7 and the second lower special-shaped copper block 8.8, which are in close contact to form a detection circuit.

[0066] In this embodiment, if Figure 6 The figure shows a wiring diagram of the special-shaped copper block and the core detector. The first upper special-shaped copper block 8.5 and the first lower special-shaped copper block 8.6 are respectively connected to the voltage terminals of the core detector 12, and the second upper special-shaped copper block 8.7 and the second lower special-shaped copper block 8.8 are respectively connected to the current terminals of the core detector 12.

[0067] like Figure 7 The figure shows a schematic diagram of the overall structure of the material receiving device, wherein the material receiving device 9 comprises a material receiving clamp 9.1 and a material receiving slide 9.2, wherein the material receiving slide 9.2 is arranged at the discharge end of the material receiving clamp 9.1.

[0068] In this embodiment, the overall structure of the material receiving device 9 is welded and sprayed with square tubes, and is closed on all sides with aluminum plates and fixed with screws; the material receiving clamping claws 9.1 are driven by the clamping cylinder to be loaded into the material receiving slide 9.2; the material receiving slide 9.2 is inclined, and for example, the slide inclination angle can be set to 60 degrees, and the iron core slides off the slide plate; a photoelectric sensor can also be installed at the end of the material receiving device, and an alarm will be issued when the iron core is detected, and it will be collected manually.

[0069] like Figure 8The figure shows an overall schematic diagram of a palletizing device, wherein the palletizing device 10 comprises a palletizing bracket 10.1, a pushing cylinder 10.2 is arranged on one side of the palletizing bracket 10.1, and a pushing plate 10.3 for pushing the iron core into a temporary storage area 10.4 is arranged on the top of the pushing cylinder 10.2; a plurality of clamping cylinders 10.5 are matched and arranged above the temporary storage area 10.4 along the arrangement direction of the iron cores, and the head of each clamping cylinder 10.5 is matched and arranged with an iron core clamp; a plurality of clamping cylinders 10.5 are all arranged on a lifting plate 10.6, and a lifting cylinder for controlling vertical movement is connected to the other side of the lifting plate 10.6; a slider 10.7 is connected to the other side of the lifting cylinder, and the slider 10.7 is arranged in a guide rail 10.8 and matched with a drag chain 10.9 for controlling horizontal movement.

[0070] In this embodiment, in order to prevent the iron cores after testing from violently colliding during collection and affecting the magnetism, a stacking device 10 is designed. The frame of the stacking device 10 is constructed of aluminum profiles, and the lifting plate 10.6 is driven by the lifting cylinder in the vertical direction, and the drag chain 10.9 is driven in the horizontal direction in cooperation with the guide rail 10.8 and the slider 10.7; a limit block can be installed at the end of the guide rail 10.8 to prevent it from falling out.

[0071] In this embodiment, after the iron core arrives at the stacking station, the push cylinder 10.2 drives the push plate 10.3 to push the iron core into the temporary storage area 10.4. When the temporary storage area 10.4 is full, the photoelectric sensor at the end detects the iron core, and the photoelectric sensor at the end of the temporary storage area 10.4 sends a signal to the PLC. The PLC outputs a command to drive the lifting cylinder to drive the lifting plate 10.6 to descend, and the clamping cylinder 10.5 is started. The iron core is grabbed from the temporary storage area by the clamping head, and then the lifting plate 10.6 rises;

[0072] Then, in the horizontal direction, the drag chain 10.9 cooperates with the guide rail 10.8 and the slider 10.7 to drive the iron core to a suitable horizontal position, and the lifting cylinder drives the lifting plate 10.6 to descend, and the iron core is stacked on the manually placed pallet at the bottom. The number of stacking can be set according to the actual situation. After stacking, the operator can transfer and store it with a hydraulic car and place a new pallet at the bottom, which realizes efficient stacking without affecting the magnetism of the iron core.

[0073] In this embodiment, for example, a material receiving device 9 can be used to classify the first type of iron cores after inspection, and a stacking device 10 can be used to classify the second type of iron cores after inspection; the first type of iron cores can be the iron cores screened and discharged after inspection by the iron core inspection mechanism 8, and the second type of iron cores can be the iron cores that are found to be compliant by the iron core inspection mechanism 8; the material receiving device 9 is used to discharge the iron cores, so that the operator can take them away for observation and troubleshooting.

[0074] The above are only specific application examples of the present invention and do not constitute any limitation on the protection scope of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the protection scope of the present invention.
