Description

Technical Field

[0001] The present invention relates to the technical field of iron core production, and in particular to a universal iron core punching sheet stacking and positioning tool. Background Art

[0002] In automotive motor manufacturing, core punching lamination stacking and positioning tooling is used to manufacture high-precision stator cores to ensure motor performance and reliability. Its high-precision positioning and automated operation can significantly improve production efficiency and product quality. Before the stamping process, it uses high-precision positioning structures (such as locating pins, clamps, etc.) to ensure that the punching laminations are accurately aligned during stacking to avoid offset. Its automated operation can achieve rapid loading and unloading of punching laminations, thereby improving production efficiency. In addition, its universal design can adapt to punching laminations of various specifications to meet the diverse needs of automotive battery cell manufacturing. This tooling plays an important role in improving product quality, reducing production costs and ensuring production efficiency, and is an indispensable equipment in automotive battery cell manufacturing.

[0003] The existing iron core punching lamination stacking and positioning tooling is highly dependent on manual operation during the loading process. The operator needs to manually remove the iron core sheets to be punched from the tray and place them on the preparation tooling. This process not only increases the labor intensity of the operator, but also poses certain safety risks. At the same time, frequent manual operations may also introduce impurities, affecting the cleanliness and quality of the iron core.

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] During actual use, it was found that the existing iron core punching sheet stacking and positioning tooling is highly dependent on manual operation during the loading process. The operator needs to manually remove the iron core sheets to be punched from the tray 27 and place them on the preparation tooling. This process not only increases the labor intensity of the operator, but also poses certain safety risks. At the same time, frequent manual operations may also introduce impurities, affecting the cleanliness and quality of the iron core. In order to solve the above problems, the following structure is specially invented.

[0031] like Figures 1-9 The universal iron core punching lamination stacking positioning tool shown in the figure includes a fixed table 1, and a movable platform 2 which can move back and forth laterally is provided on the fixed table 1. The movable platform 2 is mainly composed of structures such as a transverse moving component, which is a mature technology in the existing technology. It can drive the iron core on the movable platform 2 to move back and forth laterally on the fixed table 1, and can quickly transfer the stored iron core material to the bottom of the conveying mechanism 3, so it will not be described in detail here. The fixed table 1 is also provided with a conveying mechanism 3 for conveying the iron core to be loaded and unloaded in the punching machine. The conveying mechanism 3 is mainly composed of structures such as an adsorption mechanism, a transverse movement mechanism and an iron core conveying line. It can automatically take out the iron core on the lifting plate 5, put it into the positioning component on the fixed table 1, position it, and then take out the iron core again and put it into the punching machine. At the same time, it will catch the iron core punched out last time and transfer it to the blanking area. This is repeated to realize automatic loading and unloading of the iron core. A pair of The top of the outer wall of the positioning rod 7 is provided with a sunken annular groove 13, and the L-shaped block 12 can be inserted into and removed from the annular groove 13 to lock the position of the positioning rod 7.

[0032] The driving mechanism includes an upper electric telescopic cylinder 14, which is fixedly connected to the side wall of the fixed frame 11. An extrusion plate 15 is slidably connected to the inside of the fixed frame 11. An extrusion groove 16 is provided at the top of the extrusion plate 15, and both sides of the extrusion groove 16 are inclined. The top of the L-shaped block 12 passes through the bottom end of the fixed frame 11 and is fixedly connected to a T-shaped block 17. The top of the T-shaped block 17 is fixedly connected to a round rod 18, and the outer walls of the round rod 18 are in contact with the inclined surface of the extrusion groove 16. The output end of the upper electric telescopic cylinder 14 passes through the inside of the fixed frame 11 and is fixedly connected to the side wall of the extrusion plate 15.

[0033] A sliding groove that matches the T-block 17 is provided at the bottom of the fixed frame 11. The T-block 17 is slidably connected in the sliding groove. A middle block 19 is fixedly connected to the bottom end of the fixed frame 11 (it should be noted that the height of the middle block 19 is lower than the bottom of the extrusion plate 15 to avoid affecting the normal sliding of the extrusion plate 15). Three upper springs 20 are fixedly connected between the outer walls of the middle block 19 and the side walls of the T-block 17.

[0034] A U-shaped frame 26 is fixedly connected to the ground on the front and rear sides of the fixed platform 1, and a tray 27 is provided in the U-shaped frame 26. A placement groove 28 adapted to the lifting plate 5 is provided on the tray 27, and a lower side groove is provided on both sides of the placement groove 28. The inner wall of the placement groove 28 relative to the two sides of the lower side groove is provided with a card groove 29. Two pairs of installation cavities are provided inside the lifting plate 5, and the inner sides of the two pairs of installation cavities are slidably connected with U-shaped rods 30, and the U-shaped rods 30 are arranged through the side walls of the lifting plate 5. Three lower springs 31 are fixedly connected between the inner side of the installation cavity and the side walls of the U-shaped rods 30, and the bottom of each pair of U-shaped rods 30 away from one end is inclined.

[0035] A top groove is formed at the top of the U-shaped frame 26 relative to the position next to the lower side groove. L-shaped plates 32 are fixedly connected to both sides of the U-shaped frame 26. The side walls of the L-shaped plates 32 are fixedly connected to lower electric telescopic cylinders 33. The output end of the lower electric telescopic cylinder 33 passes through the side walls of the L-shaped plates 32 and is fixedly connected to a U-shaped release rod 34 for pushing the U-shaped rod 30.

[0036] During the core stamping process, the pallet 27 with the core to be processed is first positioned and placed in the U-shaped frame 26 by a forklift, and then the lower electric telescopic cylinder 33 is controlled to start and drive the U-shaped release rod 34 to move to the side close to it, and then the U-shaped release rod 34 pushes the U-shaped rod 30 to move to the middle, so that the other end of the U-shaped rod 30 moves out of the slot 29 and compresses the lower spring 31 to release the position restriction of the lifting plate 5, and then the moving mechanism is controlled to move the lifter 10 and the fixed frame 11 above the pallet 27, and then the lifter 10 is controlled to start and drive the fixed frame 11 to move downward. After that, the bottom end of the fixed frame 11 is brought into contact with the top end of the positioning rod 7, and the upper electric telescopic cylinder 14 can be controlled to start and drive the extrusion plate 15 to move backward, and then gradually push the extrusion round rod 18 to slide toward the middle through the inclined surfaces on both sides of the extrusion groove 16, while driving the T-shaped block 17 and the L-shaped plate 32 to move toward the middle, and gradually compressing the upper spring 20, and then the L-shaped block 12 is inserted into the annular groove 13 on the positioning rod 7, thereby achieving the locking of the four positioning rods 7, and then the lifter 10 can be controlled to start and drive the fixed frame 11 and the L-shaped block 12 to move upward, while driving the positioning rod 7, the iron core and the lifting plate 5 to move upward.

[0037] Then, the moving mechanism is controlled to move the lifter 10 and the lifting plate 5 above one of the rectangular slots 4 of the moving platform 2, and then the lifter 10 is controlled to drive the fixed frame 11 to move downward so that the lifting plate 5 is placed in the rectangular slot 4. At this time, the inner wall of the rectangular slot 4 will squeeze the inclined surface of the U-shaped rod 30, compressing the U-shaped rod 30 into the installation cavity (it should be noted that the adjacent end of each pair of U-shaped rods 30 will move into the upper side slot and therefore will not be obstructed). The upper electric telescopic cylinder 14 can be controlled to reset, and the above operation can be repeated in reverse to release the squeezing of the L-shaped block 12. The reset is pushed under the elastic force of the upper spring 20, and the L-shaped block 12 is removed from the annular groove 13, releasing the limit on the positioning rod 7, and the lifter 10 can be controlled to lift and remove the fixed frame 11. Finally, the moving platform 2 is controlled to move to the bottom of the conveying mechanism 3 for loading.

[0038] To sum up, through the design of the above structure, the lifting plate 5 with the iron core can be automatically removed from the pallet 27, and then positioned and placed on the mobile platform 2, thereby realizing automatic loading of the device. There is no need for workers to remove the iron core from the pallet 27 and place it on the positioning tooling, saving time and effort.

[0039] On the basis of the above embodiment, it was found during use that since the distance that the conveying mechanism 3 moves downward to pick up materials each time is fixed, if the lifting plate 5 and the positioning rod 7 are a fixed structure, then the iron core on the lifting plate 5 will gradually decrease under the material picking of the conveying mechanism 3, and the corresponding height will also gradually decrease. If the height of the lifting plate 5 is not raised, it will affect the normal material picking of the conveying mechanism 3. In order to solve the above problem, the above structure has been further improved.

[0040] The bottom end of the fixed platform 1 is provided with a bottom groove below the material-retrieving position of the conveying mechanism 3, and a pushing electric telescopic cylinder 24 is fixedly connected in the bottom groove. Through the setting of the pushing electric telescopic cylinder 24, the iron core on the mobile platform 2 can be located below the conveying mechanism 3 during the material-retrieving process, and the lifting plate 5 can be pushed upward gradually by the pushing electric telescopic cylinder 24 to ensure that the iron core on the lifting plate 5 is always in the material-retrieving position of the conveying mechanism 3, so as to avoid affecting the normal material-retrieving of the equipment. At the same time, a pushing groove is provided throughout the mobile platform 2 to avoid affecting the normal pushing of the output end of the pushing electric telescopic cylinder 24. The bottom end of the rectangular groove 4 is fixedly connected with an electromagnet 25 relative to the position below the upper inclined groove 6. The limit plate 8 is made of iron and the lifting plate 5 is made of plastic. Upper side grooves are provided at both ends of the side walls of the rectangular groove 4. Through the setting of the electromagnet 25, the positioning rod 7 can be adsorbed during the process of the lifting plate 5 being pushed up by the pushing electric telescopic cylinder 24 to ensure the stable operation of the equipment. At the same time, the positioning rod 7 can be adsorbed by the electromagnet 25 to play a positioning role on the positioning rod 7 (it should be noted that the electromagnet 25 here will not affect the iron core on the lifting plate 5).

[0041] To sum up, through the design of the above structure, the height of the iron core can be automatically raised and lowered during the subsequent material picking process of the conveying mechanism 3, avoiding affecting the conveying mechanism 3 in placing the iron core into the punching machine, and at the same time will not affect the positional relationship between the lifting plate 5 and the positioning rod 7.

[0042] On the basis of the above embodiment, it was found during use that in order to improve work efficiency, the existing positioning tooling mostly adopts a double-working conversion type material change. If the position of the fixing frame 11 can only be used at the front end of the fixing table 1, the iron core on the rear tray 27 cannot be automatically taken and placed, which is quite limited. In order to solve the above problem, the above structure has been further improved.

[0043] The moving mechanism includes a moving motor 21, a threaded rod 22 is rotatably connected to the inner side of the support frame 9, a moving block 23 is slidably connected to the inner side of the support frame 9, the moving block 23 is fixedly connected to the side wall of the lifter 10, the threaded rod 22 is threaded through and connected to the inner wall of the moving block 23, the moving motor 21 is fixedly connected to the side wall of the support frame 9, and the output end of the moving motor 21 passes through the inner side of the support frame 9 and is fixedly connected to the side wall of the threaded rod 22.

[0044] When the iron cores above the lifting plate 5 in the middle of the fixed table 1 are taken out, the pushing electric telescopic cylinder 24 is controlled to be retracted first, and the lifting plate 5 is lowered and reset under its own gravity. Then the mobile platform 2 can be controlled to move, and the iron cores stored at the front end of the mobile platform 2 are moved to the middle of the fixed table 1. At the same time, the moving motor 21 is controlled to start and drive the threaded rod 22 to rotate, thereby driving the threaded moving block 23 to move, and then driving the lifter 10 and the fixed frame 11 to move, so that the fixed frame 11 moves to the rear of the fixed table 1. Then, when the stored iron cores move to the middle of the fixed table 1, the positioning rod 7 and the lifting plate 5 can be taken out by the driving mechanism on the fixed frame 11 and placed on the empty pallet 27 at the rear, and then the pallet 27 with the iron cores to be processed is transported to the U-shaped frame 26 by the forklift transfer vehicle. The driving mechanism can be controlled to repeat the above operation to take the materials.

[0045] To sum up, through the design of the above structure, during the process of material conversion on the mobile platform 2, the mobile motor 21 can be controlled to drive the mobile block 23, the lifter 10 and the fixed frame 11 to move quickly to the rear of the fixed platform 1, thereby realizing rapid loading of both ends of the positioning tooling and improving the flexibility of the device.

[0046] On the basis of the above embodiment, it was found during use that since there are many styles of iron cores and the positioning rod 7 is inserted into the hollow part of the iron core, the sizes of the hollow parts of iron cores of different sizes are different. If the position of the positioning rod 7 is fixed, it can only be applied to iron cores of the same size, which is quite limited. In order to solve the above problem, the above structure has been further improved.

[0047] Both sides of the bottom end of the lifting plate 5 are connected to the sliding frame 35 for transverse sliding, and the limit plates 8 are inserted into the inner side of the sliding frame 35. The side of the sliding frame 35 is fixedly connected to the cross bar 36, and the top of the cross bar 36 is fixedly connected to the extrusion rod 37. The bottom end of the lifting plate 5 is connected to the conical plate 38 with inclined surfaces on both sides for transverse sliding. The bottom end of the conical plate 38 is penetrated by a lower inclined groove 39, and the extrusion rod 37 is inserted into the inner side of the lower inclined groove 39. The bottom end of the lifting plate 5 is provided with an adjustment groove, and the conical plate 38 is slidably connected to the inner side of the adjustment groove. The side wall of the lifting plate 5 is threadedly connected with a screw 40, and the side wall of the screw 40 passes through the inner side of the adjusting groove and is rotatably connected to the side wall of the conical plate 38.

[0048] The sliding frame 35 has a moving groove 41 formed at the top end of one side thereof, and the conical plate 38 is slidably connected to the inner side of the adjusting groove.

[0049] When the position of the positioning rod 7 needs to be changed according to the model of the stamping core, the screw 40 can be rotated to push the conical plate 38 to slide in the adjustment groove, and then the extrusion rod 37 is pushed to slide through the inclined surface of the lower inclined groove 39 on the conical plate 38, while driving the cross bar 36 and the slide frame 35 to move, and then driving the limit plate 8 in the slide frame 35 to move to both sides or the middle, thereby driving the positioning rod 7 to slide in the upper inclined groove 6, and realizing the change of the position of the positioning rod 7 (it should be noted that when the pusher electric telescopic cylinder 24 pushes the lifting plate 5 upward, the lifting plate 5 is pushed upward, and the lifting plate 5 is pushed upward, the lifting plate 37 is pushed upward, and the extrusion rod ... During the sliding process, the iron core gradually moves upward, and the lifting plate 5 will slide on the positioning rod 7. At this time, the positioning rod 7 will be adsorbed and fixed by the electromagnet 25. Therefore, when the lifting plate 5 and the sliding frame 35 are removed from the positioning rod 7 and the limit plate 8, the position of the positioning rod 7 will not move at will). Different types of iron cores can be used (it should be noted that the design of the positioning rod 7 can play a preliminary positioning role for the iron core, which not only ensures that it will not fall during the forklift transportation process, but also ensures the stability of the iron core during the lifting and lowering of the pusher electric telescopic cylinder 24).

[0050] To sum up, through the design of the above structure, the position of the positioning rod 7 on the lifting plate 5 can be flexibly changed according to the model of the stamped iron core, and will not affect the work of placing the iron core from the tray 27 onto the mobile platform 2, thereby greatly improving the flexibility of the device and increasing the scope of application of the equipment.

[0051] The basic principles, main features and advantages of the present invention are shown and described above.

[0052] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
