A visual inspection device for motor housing

Abstract

This utility model discloses a visual inspection device for motor housings, belonging to the field of motor housing production equipment. It includes a base with two spaced-apart belt rollers rotatably mounted on it. A conveyor belt is installed between the two belt rollers. A servo motor is fixedly mounted on the base, and its output shaft is fixedly connected to one of the belt rollers. When defective motor housings fall from the conveyor belt, they experience significant impact force; direct impact may cause surface scratches, dents, or even cracks. Through the buffering effect of flexible rings, flexible pads, and flexible gaskets, the impact force can be effectively absorbed and dispersed, reducing the risk of motor housing damage, minimizing secondary quality problems, and reducing costs incurred by the company due to product damage. This buffering design ensures that the motor housings maintain good integrity during the handling of defective products, facilitating subsequent rework, scrapping, or further analysis of the causes.

Description

Technical Field

[0001] This utility model relates to the technical field of motor housing production equipment, and in particular to a visual inspection device for motor housings. Background Technology

[0002] The motor housing is a critical component of the motor, primarily serving a protective and support function. It is typically made of metal (such as aluminum alloy or cast iron) or plastic and must possess good mechanical strength, heat dissipation, and corrosion resistance. Its design must be adapted to the motor power and operating environment; the internal structure must have a reasonable layout for components such as the stator and rotor; and the external profile must be suitable for the installation space. Furthermore, sealing, heat dissipation, and interface design must be considered to ensure stable and efficient motor operation.

[0003] Existing motor housing visual inspection equipment is an automated device for detecting appearance defects in motor housings. This equipment uses a belt conveyor to transport the motor housings to be inspected. Defective motor housings are transported to one end of the conveyor and fall off. While these defective housings can be collected in a fixed location for easy handling, the rapid fall and impact on the ground or machine base can damage them. To address these issues, we propose a new motor housing visual inspection device. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing motor housing visual inspection equipment that uses a belt conveyor to transport the motor housing to be inspected, causing the motor housing to fall rapidly and impact the ground or machine base, resulting in damage to the motor housing. Therefore, this invention proposes a motor housing visual inspection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A visual inspection device for motor housings includes a base, on which two spaced belt rollers are rotatably mounted, and a conveyor belt is installed between the two belt rollers. A servo motor is fixedly mounted on the base, and the output shaft of the servo motor is fixedly connected to one side of the belt roller. Two limiting plates are fixedly mounted on the base, respectively located on both sides of the conveyor belt, with the upper end of the limiting plates extending above the conveyor belt. A support base is fixedly mounted on the limiting plates, and a high-definition camera facing the conveyor belt is fixedly mounted at the bottom of the support base. A controller is fixedly mounted on one side of the limiting plate, and a warning light is fixedly mounted on the support base. A buffer mechanism is mounted on the base.

[0007] Preferably, both the high-definition camera and the warning light are electrically connected to the controller, which is used to control the operation of the warning light.

[0008] Preferably, a display is fixedly mounted on the limiting plate located on one side, and the display is electrically connected to the controller.

[0009] Preferably, the buffer mechanism includes a guide block located at one end of the conveyor belt and fixedly connected to the machine base. Two spaced guide sleeves are fixedly installed on the machine base. Movable blocks are inserted into each guide sleeve. The movable blocks are slidably installed on the guide sleeves. Flexible pads are placed inside the guide sleeves. A rotating roller is rotatably installed between the two movable blocks. A flexible ring is fitted over and fixedly connected to the rotating roller.

[0010] Preferably, a flexible pad is fixedly connected to the base, and the flexible pad is located below the rotating roller.

[0011] Preferably, the conveyor belt is provided with a plurality of equally spaced support rollers, the ends of which are rotatably mounted on a limiting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Defective products are conveyed to one end of the conveyor belt. They fall onto the guide block and slide downwards. When they reach the flexible ring, they come into contact with it. The impact force between the defective product and the flexible ring causes the rotating roller and the flexible ring to rotate. The flexible ring is squeezed and deformed, and the impact force acts on the rotating roller, causing it to move downwards. The movable block moves downwards within the guide sleeve, and the bottom of the movable block presses against the flexible pad, causing the flexible pad to deform. In this way, the impact force of the falling motor housing is buffered.

[0014] Defective motor housings experience significant impact when falling from the conveyor belt; direct impact can cause surface scratches, dents, or even cracks. The cushioning effect of flexible rings, blocks, and pads effectively absorbs and disperses this impact, reducing the risk of motor housing damage, minimizing secondary quality issues, and lowering costs for the company due to product damage. This cushioning design ensures the motor housing maintains good integrity during the handling of defective products, facilitating subsequent rework, scrapping, or further analysis of the cause.

[0015] Limit plates are used to restrict the motor housing of the conveyor belt, preventing it from falling out from either side of the belt. Multiple support rollers further support the conveyor belt from below, preventing the weight of the motor housing from acting on the belt and causing deformation. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-6 A visual inspection device for motor housings includes a base 1, on which two spaced belt rollers 2 are rotatably mounted, and a conveyor belt 3 is installed between the two belt rollers 2. A servo motor 4 is fixedly mounted on the base 1, and the output shaft of the servo motor 4 is fixedly connected to one side of the belt roller 2. Two limit plates 5 are fixedly mounted on the base 1, and the two limit plates 5 are respectively located on both sides of the conveyor belt 3. The upper end of the limit plates 5 extends above the conveyor belt 3. A support base 6 is fixedly mounted on the limit plates 5, and a high-definition camera 7 facing the conveyor belt 3 is fixedly mounted at the bottom of the support base 6. A controller 8 is fixedly mounted on one side of the limit plate 5, and a warning light 9 is fixedly mounted on the support base 6. A buffer mechanism is installed on the base 1.

[0025] The high-definition camera 7 and the warning light 9 are both electrically connected to the controller 8, which controls the operation of the warning light 9. A display 10 is fixedly mounted on the limit plate 5 on one side, and the display 10 is electrically connected to the controller 8.

[0026] The motor housing visual inspection device achieves automated detection of product appearance defects through the coordinated operation of a high-definition camera 7, a controller 8, a warning light 9, and a display screen 10.

[0027] By placing the motor housing to be tested on the conveyor belt 3, the servo motor 4 drives the belt roller 2 to rotate, so that the conveyor belt 3 transports the motor housing on it. The servo motor 4 intermittently drives the conveyor belt 3 to operate, and multiple motor housings are transported in sequence to the area below the high-definition camera 7 and then stop for a period of time.

[0028] The high-definition camera 7 is responsible for acquiring image data of the motor housing and capturing surface defects (such as scratches, cracks, and deformation). The high-definition camera 7 is connected to the controller 8 via a data cable to transmit image data in real time. The controller 8 is responsible for image processing, defect analysis, data storage, and system control. The controller 8 is connected to the display screen 10 via an HDMI interface to output the detection results. The display screen 10 displays the detection results in real time, including defect location, type, and statistical data.

[0029] High-definition camera 7 captures images of the motor housing, obtaining surface images. The high-definition camera 7 transmits the image data to controller 8. Controller 8 performs noise reduction, enhancement, and binarization operations on the image to improve image quality. Feature information of the housing surface is extracted using edge detection and texture analysis techniques. Defects are classified and located using a deep learning model. The number, type, and distribution of defects are then tallied, generating an inspection report. Controller 8 transmits the inspection results (including defect images, locations, and types) to display screen 10, which displays the results in real time.

[0030] According to the preset threshold, when a defective product is detected, the controller 10 controls the warning light 9 to light up, while the qualified product is taken out from the conveyor belt 3 by the staff.

[0031] The buffer mechanism includes a guide block 11, which is located at one end of the conveyor belt 3 and fixedly connected to the base 1. Two spaced guide sleeves 12 are fixedly installed on the base 1, and each guide sleeve 12 has a movable block 13 inserted inside it. The movable block 13 is slidably mounted on the guide sleeve 12. A flexible pad 14 is placed inside the guide sleeve 12. A rotating roller 15 is rotatably mounted between the two movable blocks 13. A flexible ring 16 is fitted over and fixedly connected to the rotating roller 15. A flexible gasket 17 is fixedly connected to the base 1 and is located below the rotating roller 15.

[0032] Defective products are conveyed to one end of conveyor belt 3. They fall onto guide block 11 and slide downwards. The defective product slides to flexible ring 16 and comes into contact with it. The impact force between the defective product and flexible ring 16 causes roller 15 and flexible ring 16 to rotate, compressing and deforming the flexible ring 16. The impact force also acts on roller 15, causing it to move downwards. Movable block 13 moves downwards within guide sleeve 12, and its bottom presses against flexible pad 14, causing the flexible pad 14 to deform. This buffers the impact force of the falling motor housing. Next, the motor housing slides to one side on flexible ring 16 and then falls onto flexible pad 17, which protects the motor housing.

[0033] Defective motor housings experience significant impact when falling from the conveyor belt; direct impact can cause surface scratches, dents, or even cracks. The cushioning effect of flexible rings, blocks, and pads effectively absorbs and disperses this impact, reducing the risk of motor housing damage, minimizing secondary quality issues, and lowering costs for the company due to product damage. This cushioning design ensures the motor housing maintains good integrity during the handling of defective products, facilitating subsequent rework, scrapping, or further analysis of the cause.

[0034] The conveyor belt 3 is equipped with multiple equidistantly distributed support rollers 18, the ends of which are rotatably mounted on the limiting plate 5. The limiting plate 5 limits the motor housing of the conveyor belt 3, preventing it from falling out from either side of the conveyor belt 3. The multiple support rollers 18 also provide support from below the conveyor belt 3, preventing the weight of the motor housing from acting on the conveyor belt 3 and causing deformation.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
