[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic loading and unloading device for bottom paper of a motor stator slot. Background Art

[0002] With the rapid development of compressors, the demand for motors has only increased. As the core component of the motor, the quality of the stator determines the product performance and safety of the entire motor. There are many processes in the production of stator components. Considering only the front-end processes, including stator stacking thickness detection, weight detection, outer and inner diameter detection, slot bottom paper, skeleton installation, winding, interphase paper insertion, sleeve tube, etc., although the numerous processes can always ensure the quality of the product, the efficiency is very low.

The operator first needs to determine whether the stator incoming material meets the requirements, whether the positive and negative and angular positions of the core are correct, etc. The entire inspection process is very complicated and is greatly affected by environmental and human factors. The inspection efficiency is low and the operator has a high repetitive labor intensity. Utility Model Content

[0018] Beneficial Effects

[0019] (1) In the utility model, the stator core is provided to the inspection area of ​​the visual inspection mechanism by the feeding mechanism. During this process, the stator core can be sorted by the sorting mechanism, and then the stator core at the end of the sorting mechanism is transferred to the inspection area by the cutting mechanism for photographing and inspection by the visual inspection mechanism.

[0020] (2) In the utility model, under the support of the support, the cutting tooling plate can be driven to move in the horizontal direction through the telescopic component, so that the positioning groove moves back and forth between the end of the sorting belt and the detection area. Since the position of the stator core in the positioning groove is relatively fixed, the position of the positioning groove on the cutting tooling plate is fixed, which can ensure that the position of the stator core in the detection area is relatively stable, thereby improving the accuracy of the detection result of the visual inspection mechanism.

[0037] like Figure 1-Figure 2 As shown, a motor stator slot bottom paper automatic loading and unloading device includes a slot bottom paper machine 1, a feeding mechanism 2, a sorting mechanism 3, a visual inspection mechanism 4, a cutting mechanism 5, a feeding mechanism 6, a transfer mechanism 7 and a clamping mechanism 8; wherein the feeding mechanism 2, the feeding mechanism 6 and the transfer mechanism 7 are distributed on the peripheral side of the slot bottom paper machine 1, and the transfer mechanism 7 is located between the slot bottom paper machine 1 and the feeding mechanism 2; the sorting mechanism 3 is arranged at the end of the feeding mechanism 2, the visual inspection mechanism 4 and the cutting mechanism 5 are arranged at the end of the sorting mechanism 3, and the clamping mechanism 8 is arranged at the output end of the transfer mechanism 7.

[0038] The slot bottom paper machine 1 adopts the existing technology. It only needs to place the qualified stator core on the gear plate tooling 11, and the slot bottom paper machine 1 can automatically complete the slot bottom paper operation of the stator core, and the gear plate tooling 11 here adopts servo drive. The slot bottom paper machine 1 is a single slot paper insertion, using servo paper feeding and servo gear plate. The length size of the paper and the insertion accuracy are guaranteed, and the equipment can be equipped with marking equipment and linked

[0039] like Figure 1-Figure 3 , Figure 7 As shown, the feeding mechanism 2 is used to feed the stator cores to be inspected to the inspection area of ​​the visual inspection mechanism 4, and in this process, the stator cores are sorted by the sorting mechanism 3 so that the inspection work can be carried out in an orderly manner.

[0040] The feeding mechanism 2 includes a feeding bracket 21, a feeding belt 22 for conveying the stator core is arranged on the top of the feeding bracket 21, feeding baffles 23 are arranged on both sides of the feeding belt 22, and the end of the feeding belt 22 is spliced ​​with the sorting mechanism 3. The front end of the feeding belt 22 can be manually fed, or connected to the stator core punch press to realize full-automatic feeding, and the feeding belt 22 conveys the stator core to the sorting mechanism 3 for sorting, and the feeding baffles 23 on both sides can prevent the stator core from accidentally falling.

[0041] The sorting mechanism 3 includes a sorting bracket 31 and a sorting belt 32 arranged on the top of the sorting bracket 31. Sorting baffles 33 are arranged on both sides of the sorting belt 32. A notch is opened on the sorting baffle 33 close to the side of the feeding belt 22 to allow the stator core on the feeding belt 22 to enter the sorting belt 32.

[0042] As mentioned above, the sorting bracket 31 is fixedly installed on one side of the loading bracket 21, and the distance between the sorting baffles 33 on both sides only allows the stator cores to pass one by one, that is, the spacing between the sorting baffles 33 on both sides is only slightly larger than the outer diameter of the stator core. The purpose of this structure is to separate the stator cores so that they can pass through the cutting mechanism 5 in an orderly manner and enter the detection area of ​​the visual inspection mechanism 4.

[0043] In order to facilitate the stator cores to be arranged in a line, a guide plate 24 is provided above the feeding belt 22, and its function is to disperse the batches of stator cores; and one end of the guide plate 24 is connected to the feeding baffle 23 on one side, and a channel connected to the sorting belt 32 is formed between the other end and the feeding baffle 23 on the other side, so as to limit the stator cores from passing through one by one, so that they are distributed in a line on the sorting belt 32.

[0044] The guide plate 24 preferably adopts an arc-shaped structure and is tilted between the loading baffles 23 on both sides; the stator cores in the same row have the same moving speed. After being blocked by the guide plate 24, some of the stator cores will change their positions and converge to the channel along the protruding direction of the guide plate 24, ultimately achieving the purpose of the stator cores passing through one by one, that is, the width of the channel also limits only one stator core to enter the sorting belt 32 at a time.

[0045] Furthermore, the unloading mechanism 6 includes an unloading bracket 61, a unloading belt 62 for conveying the stator core is arranged on the top of the unloading bracket 61, unloading baffles 63 are arranged on both sides of the unloading belt 62, and the transfer mechanism 7 can transfer the stator core located on the gear plate tooling 11 to the unloading belt 62 through the clamping mechanism 8.

[0046] Among them, the structures of the feeding mechanism 2, the sorting mechanism 3 and the unloading mechanism 6 are the same, only the conveying direction of the belt and the size of the bracket are different. The feeding belt 22, the sorting belt 32 and the unloading belt 62 all adopt the existing belt conveying technology. The working surfaces of the three are at the same horizontal height, and the bottoms of the feeding bracket 21, the sorting bracket 31 and the unloading bracket 61 are all provided with feet so that they can be stably installed on the bottom surface.

[0047] A feeding area is reserved at the front end of the feeding belt 22, which can be connected to the stator core punch press for automatic feeding or manual feeding according to the use requirements of the workshop. The feeding guide plate 24 can specify the movement direction and quantity of the product, and the feeding belt 22 and the sorting belt 32 are vertically connected.

[0048] like Figure 3-Figure 5 As shown, the stator cores arranged in order by the sorting mechanism 3 enter the cutting mechanism 5 one by one, and are transported by the cutting mechanism 5 to the inspection area of ​​the visual inspection mechanism 4 for visual inspection, including but not limited to inspection of the height and quality of the stator.

[0049] The visual inspection mechanism 4 includes a mounting plate 41 fixedly connected to the sorting bracket 31 , one side of the mounting plate 41 is connected to a detection camera 45 via a pad assembly, and a sheet metal 47 for mounting a light source is also provided on the outer side of a lens 46 of the detection camera 45 .

[0050] The visual inspection mechanism 4 adopts the Keyence visual system to perform angular position correction before the transfer mechanism 7 and the clamping mechanism 8 place the stator core on the slot bottom paper machine 1; the mounting plate 41 and the inspection camera 45 are connected by a pad assembly to effectively ensure the position accuracy of the inspection camera 45; the sheet metal 47 is in a circular ring structure, and a circular light source is installed on the inside thereof to assist the inspection camera 45 in completing the photo inspection of the stator core.

[0051] The pad assembly includes two horizontal pads 42 arranged opposite to each other, one end of the two horizontal pads 42 is fixedly connected to the mounting plate 41, and the other end is fixedly connected through the longitudinal pad 43. A connecting plate 44 is also fixedly installed on one side of the longitudinal pad 43, and the detection camera 45 is fixedly installed in the groove of the connecting plate 44. The material of the pad assembly is FR4 epoxy resin, which can ensure that the operation of the camera is not affected.

[0052] As mentioned above, the cutting mechanism 5 is located below the lens 46, and its function is to transport the product to the inspection area, that is, to separate a product to enter the next process and to block the next product to perform various inspections on the current product.

[0053] The cutting mechanism 5 includes a cutting tooling plate 51, a support 52 and a telescopic component 53. The support 52 is fixedly connected to the sorting bracket 31, and a reinforcing rib is arranged on the inner side to ensure that the mechanism does not shake, thereby ensuring the accuracy and reliability of the detection. The telescopic component 53 is installed on the top of the support 52, and the output end of the telescopic component 53 is connected to the cutting tooling plate 51, and a positioning groove 511 capable of accommodating the stator core is opened on the cutting tooling plate 51.

[0054] The telescopic component 53 preferably adopts a sliding cylinder, that is, the cutting tooling plate 51 is located above the telescopic component 53. Under the drive of the sliding cylinder, the positioning groove 511 can move horizontally between the end of the sorting belt 32 and the detection area. One side of the positioning groove 511 is open to facilitate the stator core to enter the positioning groove 511 from the sorting belt 32; the cylinder stroke is 100mm, and when the cylinder is extended, the product enters the positioning groove 511 of the cutting tooling plate 51; when retracted, the cutting tooling plate 51 blocks the next product and performs various inspections on the current product.

[0055] like Figure 1-Figure 2 , Figure 6 As shown, in the device, through the cooperation between the transfer mechanism 7 and the clamping mechanism 8, the product can be transported from the cutting tooling plate 51 to the gear plate tooling 11 of the slot bottom paper machine 1 for slot bottom paper operation, and the product with completed paper insertion can be transported from the gear plate tooling 11 to the unloading belt 62, and the staff only needs to collect the material at the end of the unloading belt 62.

[0056] As mentioned above, the transfer mechanism 7 includes a transfer bracket 71 , a four-axis robot 72 is installed on the top of the transfer bracket 71 , and the clamping mechanism 8 is installed at the output end of the four-axis robot 72 .

[0057] The four-axis robot 72 adopts the existing technology, which includes three rotational degrees of freedom that can rotate around the vertical axis and the translational degree of freedom that can rise and fall along the vertical axis. The four-axis robot 72 can drive the clamping mechanism 8 to move freely in the space and has high flexibility; when working, the transfer bracket 71 is fixed, and the end of the four-axis robot 72 drives the clamping mechanism 8 to transport the stator core.

[0058] The clamping mechanism 8 includes a first clamping jaw 81 and a second clamping jaw 82 which are independent of each other, and the first clamping jaw 81 and the second clamping jaw 82 are both installed at the output end of the four-axis robot 72. The first clamping jaw 81 and the second clamping jaw 82 are preferably pneumatic clamping jaws, and the inner side of the clamping jaws is provided with a notch that matches the outer contour of the stator core, so as to better clamp the stator core.

[0059] Working principle:

[0060] After the feeding belt 22 is loaded (manually or automatically), the product enters the sorting belt 32 from the guide plate 24. The sorting belt 32 is only slightly wider than the product, and the products are arranged in a line; then the slide cylinder extends, and the product at the end of the sorting belt 32 enters the positioning groove 511 of the cutting tooling plate 51 to achieve cutting; after the slide cylinder retracts, the visual inspection mechanism 4 inspects the product;

[0061] The four-axis robot 72 uses the first clamp 81 to grab the product after inspection, puts it on the servo gear plate tooling 11 in the automatic slot bottom paper machine 1, and uses the second clamp 82 to grab the product after paper insertion to the unloading belt 62, and the staff can collect the material at the end of the unloading belt 62.
