Description

[0002] Silicon steel is an iron-silicon alloy with a silicon content of 0.5% to 4.8%. It is a soft magnetic material widely used in the electrical field. Silicon steel sheets are made of silicon steel and are widely used in the fields of motors, transformers, and electromagnetic structures. In the lamination of silicon steel sheets, in order to ensure the convenience of downstream processes and transportation requirements, the silicon steel sheets need to be fixed in length, stacked, rod-pierced, and rubber-covered. At present, in the field of transformer manufacturing, manual lamination is mostly used for the lamination of rotor silicon steel sheets. For example, in the silicon steel sheets punched by a punch press at high speed, when the punch press has a punching speed of 300 times / min and is equipped with a punching die with 6 outlets, at least two staff members are required to continuously take the silicon steel sheets, and then increase and decrease the silicon steel sheets according to the fixed measuring tool to ensure the fixed length, rod-pierced, rubber-covered, and the silicon steel sheets are placed in order according to the direction. The punching speed of the punch press is restricted by the efficiency of the staff and cannot be improved, and the number of staff is restricted by the operating area and cost factors and cannot be increased. Therefore, there are problems in production such as low efficiency, large errors, and high labor intensity of the staff in laminating silicon steel sheets. Summary of the invention

[0054] The device also includes an automatic control system for controlling various parts of the device. The control system adopts PLC. The operation panel 10 of the automatic control system is arranged on the side of the frame 1. A three-color light 9 for indicating the working state of the device is also arranged on the top of the frame 1. It also includes a feeding mechanism 7, which includes a feeding clamp 701 and a feeding motion module 702. The feeding mechanism 7 is used to lift the silicon steel sheets separated by fixed length in the fixed length separation mechanism 4 into the finished product box 8. The feeding mechanism 7 is a mature device existing in the prior art, so it will not be described in detail.

[0055] It should be noted that if Figure 2 and 3In the embodiment shown, the number of silicon steel sheet feed buffer mechanisms 3 is six, the number of separation buffer channel units 410 is six, and the number of rod fixing boxes 601 is six. It is generally required that the number of the above three mechanisms is the same. The specific number of the above three mechanisms can be set according to production needs and adapted to the discharge equipment of the upstream equipment (for example, punch press). In general, the number of silicon steel sheet feed buffer mechanisms 3 is 3 to 8. In addition, if Figure 5 As shown, the number of branches of the rubber sleeve conveyor belt 502 and the rubber sleeve insertion devices 510 is seven, the number of the rubber sleeve insertion devices 510 is one more than the number of the silicon steel sheet feeding cache mechanism 3, and the silicon steel sheet feeding cache mechanism 3 is arranged between every two rubber sleeve insertion devices 510. This arrangement is to facilitate that when the separation cache channel unit 410 is translated to different positions, the silicon steel sheets 2 that have completed the insertion rod therein can all complete the action of putting on the rubber sleeve 514.

[0056] As a better embodiment of the present invention, in order to improve the automation level of the equipment and ensure the efficient and safe operation of the equipment, Figure 7 As shown, a positioning sensor 306 for detecting the buffer length of the silicon steel sheet 2 is also provided on the silicon steel sheet feeding buffer mechanism 3. At least two positioning sensors 306 are provided, which are respectively located at the front end and the rear end of the silicon steel sheet feeding buffer mechanism 3. When the silicon steel sheet 2 is stacked at a specified position, the positioning sensor 306 will send a signal that the silicon steel sheet buffering is completed.

[0057] As a better embodiment of the present invention, in order to further improve the working flexibility and working efficiency of the equipment, as Figures 10-11 As shown, the plug rod transverse translation mechanism 620 also includes a plug rod fixing box slide rail 626 arranged on the translation mechanism bracket 621, the plug rod fixing box 601 is movably arranged on the plug rod fixing box slide rail 626, and a plug rod fixing box transverse pushing cylinder 625 is arranged on the side of each plug rod fixing box 601, wherein the number of the plug rod fixing box slide rail 626 is two, which are respectively arranged at the front end and the rear end of the plug rod fixing box 601, the plug rod fixing box 601 is connected to the plug rod fixing box slide rail 626 through a slider arranged on its body, and each plug rod fixing box 601 is provided with a plug rod fixing box transverse pushing cylinder 625, and the plug rod fixing box transverse pushing cylinder 625 can independently control the corresponding plug rod fixing box 601 to move and stop laterally, so that all the plug rod fixing boxes 601 can translate as a whole along with the translation mechanism bracket 621, and each plug rod fixing box 601 can also translate individually. When the equipment rhythm meets the requirements, all the rod fixing boxes 601 move as a whole to participate in the work through the translation mechanism bracket 621 that moves left and right at the bottom; when the rhythm needs to be improved, each channel needs to be fed separately, and each rod fixing box 601 can move separately with the channel to participate in the work.

[0058] As a more preferred embodiment of the present invention, in order to ensure that the silicon steel sheet 2 does not deviate or jump during the fixed-length separation process and to ensure the normal and safe operation of the device, Figure 8 and 9 As shown, each separation cache channel unit 410 also includes a separation clamping device for clamping the silicon steel sheet 2, and the separation clamping device includes a separation clamping driver 415 and a right clamping block 407 and a left clamping block 408 arranged on both sides of the separation clamping driver 415. When fixed-length separation is performed, the separation clamping driver 415 will drive the right clamping block 407 and the left clamping block 408 to clamp the silicon steel sheet 2 near the separation area.

[0059] As a better embodiment of the present invention, in order to improve the production efficiency and ensure that two insertion rods 603 can be inserted at the same time, the material channel 602 in the insertion rod fixing box 601 is two vertically arranged material channels 602, and the material channel 602 can hold L-shaped insertion rods.

[0060] It should be noted that the separation clamping driver 415, the clamping device 405, the rubber sleeve transfer push rod 515 and the feed clamping block 307 in this equipment can use electric or pneumatic methods during the clamping or pressing process, and are not limited to one of them. However, because the pneumatic method is more efficient and easier to control, the pneumatic method is preferred, and a cylinder is used to control the action of the above-mentioned devices.

[0061] To achieve the above object, the present application also provides a method for automatically stacking silicon steel sheets at a fixed length, Figures 2-3 The embodiment shown is used to illustrate the method for automatically laminating silicon steel sheets at a fixed length, which comprises the following steps:

[0062] The first step is to fill the plug rod 603 into the plug rod fixing box 601 and fill the rubber sleeve into the rubber sleeve storage box 501. This step is completed manually by the staff.

[0063] The second step is to start the equipment and cache the silicon steel sheets 2 transported from the upstream equipment into the silicon steel sheet feeding cache mechanism 3. After the cache is completed, the silicon steel sheets 2 are pushed into the right channel of the fixed-length separation mechanism 4.

[0064] In the third step, after the silicon steel sheet 2 is in place, the clamping device 305 clamps the silicon steel sheet 2, and the left and right clamping blocks clamp the silicon steel sheet 2 near the separation area. Then, the directional rod-penetrating mechanism 6 first inserts a rod into the silicon steel sheet 2 in the fixed-length separation mechanism 4, and the fixed-length separation mechanism 4 then translates to perform fixed-length separation of the silicon steel sheet 2 therein. In the subsequent cycle process, there is a situation where the silicon steel sheet feeding buffer mechanism 3 needs to be pushed to the fixed-length separation mechanism 4 as soon as possible. At this time, the fixed-length separation mechanism 4 first performs fixed-length separation of the silicon steel sheet 2 therein, and the directional rod-penetrating mechanism 6 after automatic translation then inserts a rod into the silicon steel sheet 2 in the fixed-length separation mechanism 4.

[0065] In the fourth step, the rubber sleeve 514 is put on the front end of the completed insertion rod 603 by the rubber sleeve inserting device 510, and the silicon steel sheet 2 with the completed insertion rod is lifted off by the unloading mechanism 7; at the same time, the silicon steel sheet feeding buffer mechanism 3 pushes the silicon steel sheet 2 into the left channel of the fixed-length separation mechanism 4;

[0066] The fifth step is to repeat the operation steps of the third and fourth steps according to the current operation status, and perform the work of caching, pushing, separating at a fixed length after inserting a rod (or inserting a rod after separating at a fixed length), putting on a rubber sleeve, and lifting the silicon steel sheet 2.

[0067] It should be noted that, among the above steps, only the first step is implemented manually, and the remaining steps are all automatically operated by the equipment; during the entire operation of the device, the feed buffer channel 302 is long enough to continuously receive silicon steel sheets from the upstream process; when the equipment rhythm requirement is not high, each channel of the device synchronously completes the work of caching, pushing, fixed-length separation after rod insertion (or fixed-length separation after rod insertion), and rubber sleeve installation; when the equipment rhythm requirement is high or the upstream equipment supplies silicon steel sheets 2 to each channel at different speeds, thanks to the fact that each rod fixing box 601 can be translated as a whole or independently, each channel of the device can work independently according to the rhythm of the channel, and independently complete the work of caching, pushing, fixed-length separation after rod insertion (or fixed-length separation after rod insertion), and rubber sleeve installation.

[0068] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions and substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the protection scope of the present invention.
