Detailed Implementation

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Reference Figures 1-6 An automatic stacking and positioning device for silicon steel sheets of motor stator includes a conveyor 100, a fixed box 101 is provided at the right end of the conveyor 100, a connecting box 105 is provided between the conveyor 100 and the fixed box 101, and a positioning mechanism 200 is provided in the connecting box 105.

[0027] The positioning mechanism 200 includes a geared motor 201, which is fixedly mounted on the connecting box 105. A rotating rod 202 is fixedly connected to the output end of the geared motor 201. Multiple bearing plates 203 are fixedly sleeved on the rotating rod 202 at equal intervals. The bearing plates 203 support silicon steel sheets. One end of the bearing plate 203 is in the shape of an inner arc. A hydraulic cylinder 204 is symmetrically fixedly mounted on the upper end face of the connecting box 105. The extension and retraction of the two hydraulic cylinders 204 are fixedly connected to a pressure plate 205. The pressure plate 205 presses on the silicon steel sheet to position and fix the silicon steel sheet.

[0028] When cylinder 1013 is activated, its extension and retraction end moves storage box 1014 upward, activating geared motor 201. The output of geared motor 201 drives bearing plate 203 to rotate via rotating rod 202. Bearing plate 203 rotates 180 degrees, causing silicon steel sheet to fall into fixed box 101.

[0029] The upper end of the connecting box 105 is provided with a moving component 206, which includes a first stepper motor 2061. The output end of the first stepper motor 2061 is fixedly connected to a first threaded rod 2062. The first threaded rod 2062 is threadedly connected to a first threaded sleeve 2063. The first threaded sleeve 2063 is fixedly connected to a first moving rod 2064. The lower end of the first moving rod 2064 is fixedly connected to the connecting box 105.

[0030] The output of stepper motor 2061 drives threaded rod 2062 to rotate. Threaded rod 2062 drives connecting box 105 and silicon steel sheet in connecting box 105 to move through threaded sleeve 2063 and moving rod 2064.

[0031] Furthermore, an adjustment mechanism 300 is provided at the upper end of the conveyor 100. The adjustment mechanism 300 includes a second stepper motor 301. The output end of the second stepper motor 301 is fixedly connected to a second threaded rod 302. Multiple sets of threads in opposite directions are equally spaced on the second threaded rod 302. Multiple second threaded sleeves 303 are connected to the equally spaced threads on the second threaded rod 302. Each second threaded sleeve 303 is fixedly connected to a second moving rod 304. The lower end of each second moving rod 304 is fixedly connected to a partition plate 104.

[0032] The output of the second stepper motor 301 drives the second threaded rod 302 to rotate clockwise. The second threaded rod 302 can drive the partition 104 to move through the second threaded sleeve 303 and the second moving rod 304. The two corresponding partitions 104 move relative to each other and press against the silicon steel sheet, pushing the silicon steel sheet to the middle of the two partitions 104. The output of the second stepper motor 301 rotates in the opposite direction, and the two corresponding partitions 104 move away from each other and separate from the silicon steel sheet.

[0033] Furthermore, a rectangular plate 1011 is provided on the fixed box 101, and a fixed plate 1012 is fixedly connected to the rectangular plate 1011. Two cylinders 1013 are symmetrically fixedly connected to the fixed plate 1012. The telescopic ends of the two cylinders 1013 are jointly fixedly connected to the storage box 1014. The fixed box 101 has a placement opening. The fixed plate 1012, cylinders 1013 and storage box 1014 are placed in the placement opening. When the cylinders 1013 are activated, the telescopic ends of the cylinders 1013 drive the storage box 1014 to move upward.

[0034] Specifically, a fixed frame 103 is fixedly connected to the fixed box 101. The first stepper motor 2061 is fixedly installed on the fixed frame 103. The end of the first threaded rod 2062 facing away from the first stepper motor 2061 is rotatably connected to the fixed frame 103. A first sliding rod 2065 is fixedly connected to the first threaded sleeve 2063. The upper end of the first sliding rod 2065 is slidably connected to the fixed frame 103. The setting of the first sliding rod 2065 can limit the first threaded sleeve 2063 to prevent the first threaded sleeve 2063 from rotating with the first threaded rod 2062.

[0035] Specifically, the conveyor 100 is fixedly connected to the mounting frame 102, the second stepper motor 301 is fixedly mounted on the mounting frame 102, the end of the second threaded rod 302 facing away from the second stepper motor 301 is rotatably connected to the mounting frame 102, each second threaded sleeve 303 is fixedly connected to a second slide rod 305, and the upper end of each second slide rod 305 is slidably connected to the mounting frame 102. The setting of the second slide rod 305 can limit the second threaded sleeve 303 and prevent the second threaded sleeve 303 from rotating together with the second threaded rod 302.

[0036] In this invention, multiple silicon steel sheets are placed on a conveyor 100, with each sheet positioned between two partitions 104. A second stepper motor 301 is started, its output driving a second threaded rod 302 to rotate clockwise. The threaded rod 302, through a second threaded sleeve 303 and a second moving rod 304, moves the partitions 104, causing them to move relative to each other. The partitions 104 then press against the silicon steel sheets, pushing them to the middle of the partitions. The output of the second stepper motor 301 rotates in the opposite direction, causing the two partitions 104 to move away from each other and separate from the silicon steel sheets. The conveyor 100 moves the silicon steel sheets to the right, where they enter the connecting box 105. A hydraulic cylinder 204 is then started, its extension and retraction causing the pressure plate 205 to move downwards. The pressure plate 205 presses down on the silicon steel sheet to position and fix it. The first stepper motor 2061 is started. The output end of the first stepper motor 2061 drives the first threaded rod 2062 to rotate. The first threaded rod 2062 drives the connecting box 105 and the silicon steel sheet in the connecting box 105 to move through the first threaded sleeve 2063 and the first moving rod 2064. It moves to the top of the fixed box 101 through the moving component 206. The cylinder 1013 is started. The telescopic end of the cylinder 1013 drives the storage box 1014 to move upward. The reduction motor 201 is started. The output end of the reduction motor 201 drives the bearing plate 203 to rotate through the rotating rod 202. The bearing plate 203 rotates 180 degrees and the silicon steel sheet falls into the storage box 1014. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0037] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
