DETAILED DESCRIPTION

[0035] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0036] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0037] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] like Figure 1-7 As shown, the DC small motor shaft automatic positioning and full-view quality inspection and testing device includes a lower frame 1 with a power distribution cabinet, air conditioner and computer case, which serves as a basic load-bearing component and provides a mounting platform and control core for the main body, ensuring that the device will not tilt, shake or sink due to excessive weight during the inspection process, ensuring the smooth progress of the inspection work. A profile frame protective cover 2 with a plexiglass door and a testing device body 3 are installed on the lower frame 1 with a power distribution cabinet, air conditioner and computer case, which cooperate with each other to form a stable overall structure, improve the stability of the device, and protect the internal components, forming a certain working space, which is convenient for the staff to operate and maintain. Among them, the detection equipment body 3 is driven by the operating mechanism 31 from left to right to rotate the motor shaft for all-round detection; the direct-drive linear motor module 32 transmits the motor shaft that has been tested to the supporting mechanisms 34 on both sides below it, so that the small motor shaft can enter the next process in an orderly manner; the top product mechanism 35 is fixed at the center of the rotating platform and connected to the platform by bolts or clamps to fix and support the motor shaft for all-round detection; the bearing rolling guide plate 36 is connected to the operating mechanism 31 through a tight chain transmission system 33, and the tight chain transmission system 33 runs through the bottom of the entire mechanism to realize the shaft during inspection. The transmission inside the detection device is convenient for entering the next process; the optical monitoring mechanism 37 and the light source visual moving mechanism 38 are distributed on the two sides above the bearing rolling guide 36 through the bracket; the toggle mechanism 39 is arranged at the side and lower position of the bearing rolling guide 36 to toggle and flip the small motor shaft for detection, thereby realizing 360-degree inspection and detection of the small motor shaft; the waste discharge visual detection device 41 and the waste discharge material receiving mechanism 42 are arranged on both sides of the front end of the bearing rolling guide 36 through the supporting device to collect and repack the unqualified products; and the unloading mechanism 40 is installed at the front end of the tight chain conveyor system 33 to collect and repack the qualified products.

[0039] In the automatic positioning and full-view quality inspection and detection device for the small motor shaft, the operating mechanism 31 is one of the core components. The main components from left to right are: a downward limit plate 311 installed on the support back plate 310, which is used to place the small motor shaft. A longitudinal guide plate 312 is installed above the front end of the downward limit plate 311 to control the movement trajectory of the small motor shaft. A blocking descending plate 313 and a toothed turntable 314 are installed at the front end of the downward limit plate 311, so that the small motor shaft can smoothly enter the toothed turntable 314 for movement. The drive motor 315 is connected to the toothed turntable 314 at the rear through a transmission device to transmit the rotational motion to the toothed turntable 314. The upper stopper 316 of the product is located above the toothed turntable 314, and the product limit stopper groove 317 is arranged in front of the toothed turntable 314, which are used together to prevent the small motor shaft from falling off. The inclined blocking plate 318 and the blocking shaft plate 319 are located below the toothed turntable 314 to control the movement direction of the small motor shaft. The inspection visual camera 320 is arranged above the longitudinal guide plate 312 and directly facing the toothed turntable 314 to detect the rotation accuracy and geometric parameters of the small motor shaft.

[0040] The direct-drive linear motor module 32 includes a slide plate 321 and a cylinder coupling block 322. The cylinder coupling block 322 is installed at the front end of the slide plate 321 to control the small motor shaft to pass smoothly to the next station.

[0041] The waste discharging and receiving mechanism 42 mainly includes: a cylinder 421 and a push rod 422. The cylinder 421 is connected to the push rod 422 at the front end through relevant transmission components. The cylinder 421 is mainly used as a power element. When the small motor shaft is detected to be waste, the piston of the cylinder 421 is driven to extend, and the waste small motor shaft is pushed from the detection station to the collection area through the push rod 422.

[0042] Working principle: The DC small motor shafts enter in batches from the sliding limit plate 311 of the operating mechanism 31 of the inspection and testing device of the invention, and fall into the groove of the toothed turntable 314 in sequence under the action of the longitudinal guide plate 312 and the blocking descending plate 313. The toothed turntable 314 rotates under the drive of the driving motor 315. At the same time, during the rotation of the toothed turntable 314, the inspection visual camera 320 fixed on the longitudinal guide plate 312 will take multi-angle photos of the small motor shafts, and perform high-precision, non-contact inspection of their appearance, size, defects, etc. After the small motor shaft has completed the inspection, the small motor shaft falls smoothly into the groove of the slide plate 321 of the direct-drive linear motor module 32 under the joint positioning and guiding action of the stop block 316 above the product, the product limit groove 317, the inclined blocking plate 318 and the blocking shaft plate 319. The slide plate 321 is disengaged from the groove of the slide plate 321 under the action of the cylinder coupling block 322, and the small motor shaft is transferred to the two side support mechanisms 34 below it, and transported forward in an orderly manner to the next workstation. At the next workstation, the product-pushing mechanism 35 fixes and supports the small motor shaft to ensure that the center line of the small motor shaft is aligned with the center line of the detection device to ensure the detection accuracy. Then, under the continued transportation of the tight chain conveyor system 33, it reaches the next workstation. Under the bearing and transportation of the rolling guide plate 36, it moves forward steadily, undergoes preliminary inspection by the optical monitoring mechanism 37 and the light source visual moving mechanism 38, and then undergoes toggle and flip inspection of the small motor shaft by the toggle mechanism 39, thus achieving 360-degree all-round inspection of the small motor shaft. The inspected products are continuously transported by the tight chain conveying system 33, and qualified products are directly transported to the qualified shaft receiving mechanism 42 for packaging; unqualified products will undergo secondary inspection under the waste discharge visual inspection device 41. When the small motor shaft is detected to be a waste product, the waste discharge receiving mechanism 42 will use the cylinder 421 as the power source, and push the waste small motor shaft from the inspection station to the waste discharge receiving mechanism 43 through its own push rod 422, thus completing the fully automatic inspection of the DC small motor shaft.

[0043] The present invention integrates multiple detection functions, can realize comprehensive intelligent and high-precision detection, can quickly conduct continuous and comprehensive detection of a large number of small motor shafts, timely discover potential quality problems, and improve product safety and stability. Compared with manual detection, it greatly reduces labor costs, avoids visual fatigue and errors that may be caused by long-term manual detection, and can more rationally allocate human resources.

[0044] The DC small motor shaft automated full-view inspection and testing device greatly shortens the inspection time of small motor shafts, ensures the accuracy and reliability of the inspection results, can improve product quality, guarantee production efficiency and management level, meet the inspection needs of large-scale production of small motor shafts, and speed up product production and delivery. It is an indispensable and important equipment in modern manufacturing.

[0045] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of the present disclosure omits the detailed description of known functions and known components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment.

[0046] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
