Description

Technical Field

[0001] The invention belongs to the technical field of motors, and in particular relates to an automatic pin-insertion device for a motor winding skeleton and a detection system thereof. Background Art

[0002] The motor winding frame is mainly composed of pins and a frame body. The shape of this motor winding frame is usually an arc structure, and then the coil is wound on the outside of it and located on the outside of the motor. Generally, the frame body is made of plastic and the pins are made of metal. During the current processing, a single pin is inserted into the frame body, and the pins are inserted one by one into the frame body.

[0003] In Chinese patent application number CN202022354679.8, a fully automatic motor winding skeleton pin insertion machine is disclosed, including a frame, a skeleton conveying mechanism, a pin supply processing unit, and a detection mechanism. The pin supply processing unit is used to process the pin wire from top to bottom and transmit it to the skeleton that needs pin insertion on the skeleton conveying mechanism below. When inserting the pin, this structure inserts the pin wire one by one at the front end position of the skeleton. Since the position of the pin wire remains unchanged during the insertion process, and the skeleton is always moving with the conveying device at the bottom, due to certain deviations in the conveying device itself, the position deviation occurs during pin insertion, that is, the spacing between the two groups of pins on the same product is quite different, and the qualified rate is low. When the conveyor belt has been running for a period of time, it needs to be adjusted in time to avoid greater errors. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1 As shown, the embodiment of the present invention provides an automatic pin insertion device for a motor winding skeleton, including a feeding mechanism 2, a first material shifting mechanism 3, a pin feeding mechanism 4, a second material shifting mechanism 5, a detection mechanism 6, and a sorting mechanism 7. Figure 2 As shown, the feeding mechanism 2 is used for feeding U-shaped materials; a vibrating material tray 1 is provided at the front end of the feeding mechanism 2, and the U-shaped materials are transported to the feeding mechanism 2 through the vibrating material tray 1. At this time, a transversely distributed slide 21 is provided on the feeding mechanism 2 to sort the U-shaped materials in order in the slide 21 (the front end of the U-shaped materials is outward).

[0037] like Figure 3 As shown, the first material-dispensing mechanism 3 includes a first material-dispensing cylinder 31 and a first material-dispensing cylinder 32. The first material-dispensing cylinder 31 pushes the U-shaped material to a position below the first material-dispensing cylinder 32, and then the first material-dispensing cylinder 32 pushes the U-shaped material to a position below the needle insertion group 422 where the needle feeding mechanism 4 is located;

[0038] like Figure 4As shown, the needle feeding mechanism 4 includes a needle feeding member 41 and a needle insertion member 42. The needle feeding member 41 includes a needle feeding platform 411, a needle receiving cylinder 412, and a needle feeding cylinder 413. A plurality of needle feeding channels 4111 are arranged in parallel on the upper edge of the needle feeding platform 411, and the insertion needle lines are orderly arranged in the channels 4111 (the spacing between each two groups of needle feeding channels 4111 is the same as the spacing at the front end of the U-shaped material), and then the insertion needle lines extending from the bottom of the needle feeding channel 4111 are cut off by the needle receiving cylinder 412 to form insertion needles (the length of each cut is equal), and then the received insertion needles are transferred to the position of the insertion needle member 42 by the needle feeding cylinder 413 (the spacing between two adjacent groups of insertion needles is equal to the position of the front end of the U-shaped material, which is convenient for alignment and correction). The pin member 42 includes a pin cylinder 421 and a pin group 422. The needle feeding cylinder 413 transfers the pin to the front end where the pin group 422 is located. At the same time, multiple groups of U-shaped materials are distributed in an array on the pin group 422, and the U-shaped materials are squeezed forward by the pin cylinder 421 (the stroke of the pin cylinder 421 can be controlled each time it runs to meet the needs of different products for the extension of the pin length), until the front end of each group of U-shaped materials is aligned with the two groups of pins at the same time and continues to be squeezed and fixed. Since the extended part of the rear end of the pin is blocked at this time, that is, after fixation, the pins at the front end of the U-shaped material are all flush structures, which greatly reduces the efficiency of alignment and correction.

[0039] like Figure 5 As shown, the second material shifting mechanism 5 includes a second material pushing cylinder 51 and a second material shifting cylinder 52. The second material shifting cylinder 52 shifts the U-shaped material with the inserted pins onto the U-shaped frame 53, and then the U-shaped material with the inserted pins is transported to the detection mechanism 6 through the second material pushing cylinder 51; the detection mechanism 6 detects the U-shaped material with the inserted pins, sorts it through the sorting mechanism 7, and then recycles it.

[0040] like Figure 6 As shown, the detection mechanism 6 includes a detection CCD61, a third material shifting cylinder 62, and a third material pushing cylinder 63. The U-shaped material with the inserted pin is pushed to the bottom of the detection CCD61 for detection by the third material shifting cylinder 62, and is pushed out by the third material pushing cylinder 63 after the detection is completed.

[0041] As shown in question 7, the sorting mechanism 7 includes a shell body 71 and a toggle member 72. At the same time, the shell body 71 located below the toggle member 72 is divided into two groups of channels. When the detection mechanism 6 detects unqualified parts and qualified parts, the toggle member 72 slides into different channels and is collected.

[0042] The detection system of the automatic pin insertion device of the motor winding frame includes the following steps:

[0043] S1. First, place the U-shaped material in the vibrating tray 1, and arrange it in order on the feeding mechanism 2 through the vibration of the vibrating tray 1.

[0044] S2. Move the U-shaped material to the position of the needle feeding mechanism 4 through the first material shifting mechanism 3. At the same time, the second material shifting mechanism 5 moves the insertion needle to the front end of the U-shaped material located at the needle feeding mechanism 4, and squeezes the rear end of the U-shaped material through the needle feeding mechanism 4, so that the insertion needle is embedded and fixed in the front end of the U-shaped material.

[0045] S3, the U-shaped parts with the pins fixed thereon are transported one by one to the bottom of the detection mechanism 6, and the U-shaped parts with the pins inserted therein are pushed to the bottom of the detection CCD 61 by the third material-displacing cylinder 62 for detection. For example, the displacement of the pin position and the occurrence of the pin shortage will trigger the detection abnormality troubleshooting of the detection system. After the detection is completed, the third material-pushing cylinder 63 will push it out to detect the product part 101 (such as Figure 8 whether the

[0046] S4. The sorting mechanism 7 receives the test results of the testing mechanism 6 and classifies and collects the product pieces 101. When the testing mechanism 6 detects unqualified pieces and qualified pieces, the moving member 72 slides them into different channels and they are collected.

[0047] The whole device is easy to operate. After the U-shaped material and the pin are respectively shifted by the first shifting mechanism and the second shifting mechanism, they are squeezed and fixed by the needle feeding mechanism, which can effectively achieve the alignment of the pin at the front end of the U-shaped material, reducing the unqualified rate of product 101.

[0048] At the same time, after the inspection and screening by the inspection agency 6, the unqualified product parts 101 are promptly recycled and processed, which greatly reduces the unqualified rate of products.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
