Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and in particular to an alignment device for visual inspection equipment of household appliance parts. Background Technology

[0002] With the continuous development of the home appliance industry, home appliances are becoming more and more powerful and complex in structure. High-precision and high-efficiency quality inspection of home appliance components is a key link to ensure the quality of home appliance products. Visual inspection technology is widely used because of its high efficiency and accuracy.

[0003] In traditional visual inspection of home appliance components, fixtures are typically used to fix the components. This method has several problems. First, the fixtures may damage the surface of the components when holding them, affecting their appearance and quality. Second, the fixtures themselves may obscure part of the component's surface, making it difficult for the visual inspection equipment to fully detect defects, thus affecting the accuracy of the inspection. In addition, the position of the components needs to be adjusted according to the inspection equipment during the inspection process, but traditional fixing methods often cannot achieve quick and accurate adjustment of the component's position, and it is difficult to ensure the stability of the component's position after adjustment. It is easy for the component to shift due to accidental contact, further affecting the reliability of the inspection results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an alignment device for visual inspection equipment of household appliance parts.

[0005] This utility model is achieved using the following technical solution: a positioning device for visual inspection equipment of household appliance parts, including an adjustment plate, a limiting groove on the upper surface of the adjustment plate, a sliding block slidably connected inside the limiting groove, a protective box fixedly connected to the upper surface of the sliding block, a lead screw threadedly connected inside the sliding block, an operating handle fixedly connected to the surface of the lead screw, a negative pressure pump fixedly installed inside the protective box, a negative pressure suction cup fixedly connected to the input end of the negative pressure pump, a locking mechanism fixedly connected to the surface of the adjustment plate, and several positioning grooves on the surface of the operating handle;

[0006] The locking mechanism includes a mounting frame, a return spring is fixedly connected to the inner wall of the mounting frame, a compression plate is fixedly connected to the surface of the return spring, a locking pin is fixedly connected to the surface of the compression plate, and a pull rod is fixedly connected to the surface of the compression plate.

[0007] The above technical solution utilizes a negative pressure pump and a negative pressure suction cup to adsorb and fix components. Compared to the traditional method of using clamps to fix components, this avoids potential clamping damage to the component surface. Simultaneously, the clamps do not obscure surface defects, thereby improving the inspection effect of subsequent testing equipment and ensuring inspection accuracy. Through the cooperation of the locking mechanism and lead screw, precise adjustment of the component position can be achieved. Furthermore, after the position is adjusted, the locking mechanism effectively restricts the rotation of the operating handle, preventing component movement due to accidental contact or external force, thus ensuring the smooth progress of subsequent inspection work.

[0008] As a further improvement to the above solution, the mounting frame is fixedly connected to the upper surface of the adjustment plate, and the locking pin is adapted to the positioning groove.

[0009] As a further improvement to the above solution, several sliding rods are fixedly connected to the lower surface of the adjusting plate, and protruding rods are fixedly connected to the surface of the sliding rods.

[0010] As a further improvement to the above solution, a support base is slidably connected to the surface of the slide rod, and a circular groove is formed on the surface of the support base.

[0011] As a further improvement to the above solution, the inner wall of the circular groove is provided with an embedded groove, and the slide rod is slidably connected inside the circular groove.

[0012] Through the above technical solution, the cooperation between the embedded groove and the protruding rod makes the sliding of the slide rod in the circular groove more precise, which can effectively avoid the slide rod from deviating during the sliding process, thereby improving the accuracy of component angle adjustment.

[0013] As a further improvement to the above solution, the protruding rod is slidably connected to the inside of the recessed groove.

[0014] As a further improvement to the above solution, a drive motor is fixedly installed inside the support base, and the output end of the drive motor is fixedly connected to the lower surface of the adjustment plate.

[0015] Through the above technical solution, the setting of the drive motor makes the angle adjustment of the parts more flexible and convenient, and can quickly and accurately adjust the orientation angle of the parts according to the actual testing needs, thereby improving the efficiency and accuracy of testing.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention uses a pull rod to disengage the locking pin from the positioning groove, unlocking the operating handle. The operator can then rotate the handle to adjust the position of the component. Once the position is adjusted correctly, releasing the pull rod causes the locking pin to re-insert into the positioning groove under the reset action of the return spring, restricting the rotation of the operating handle. This ensures the stable position of the adjusted component, effectively preventing positional shifts due to accidental contact during testing, thus improving the accuracy and reliability of the inspection. Furthermore, the use of a negative pressure pump and negative pressure suction cup to adhere and fix the component avoids clamping damage to the component surface and the obscuring of surface defects, compared to traditional methods of using clamps. This improves the testing effect of subsequent inspection equipment. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4The present embodiment of a positioning device for a visual inspection equipment for home appliance parts includes an adjustment plate 1, a limiting groove 2 on the upper surface of the adjustment plate 1, a sliding block 3 slidably connected inside the limiting groove 2, a protective box 4 fixedly connected to the upper surface of the sliding block 3, a lead screw 5 threadedly connected inside the sliding block 3, an operating handle 6 fixedly connected to the surface of the lead screw 5, a negative pressure pump 7 fixedly installed inside the protective box 4, a negative pressure suction cup 8 fixedly connected to the input end of the negative pressure pump 7, a locking mechanism 9 fixedly connected to the surface of the adjustment plate 1, and several positioning grooves 10 on the surface of the operating handle 6.

[0027] The locking mechanism 9 includes a mounting frame 901. A return spring 902 is fixedly connected to the inner wall of the mounting frame 901. A compression plate 903 is fixedly connected to the surface of the return spring 902. A locking pin 904 is fixedly connected to the surface of the compression plate 903. A pull rod 905 is fixedly connected to the surface of the compression plate 903. When the operator starts the negative pressure pump 7, the negative pressure pump 7 generates negative pressure through the negative pressure suction cup 8 at its input end, thereby adsorbing and fixing the parts to be tested. After the parts are adsorbed and fixed, the operator needs to adjust the position of the parts according to the position of the testing equipment. First, the operator pulls the pull rod 905, which drives the compression plate 903 to retract. At this time, the compression plate 903 compresses the return spring 902 and causes the locking pin 904 to disengage from the positioning groove 10 on the surface of the operating handle 6. After the operating handle 6 is unlocked, the operator can rotate the operating handle 6 normally. The rotation of the operating handle 6 will drive the lead screw 5 to rotate. The lead screw 5 is threadedly connected to the sliding block 3, so that the sliding block 3 and the protective box 4 move linearly along the limiting groove 2. The components fixed by the negative pressure suction cup 8 above the protective box 4 also move, thereby adjusting the position of the components. Once the component position is adjusted to the appropriate position, the operator slowly releases the pulling force on the pull rod 905. Under the reset action of the return spring 902, the locking pin 904 re-inserts into the positioning groove 10 on the surface of the operating handle 6, thereby restricting the rotation of the operating handle 6 and ensuring that the adjusted component position remains stable.

[0028] The mounting frame 901 is fixedly connected to the upper surface of the adjusting plate 1, and the locking pin 904 is adapted to the positioning groove 10.

[0029] Several sliding rods 11 are fixedly connected to the lower surface of the adjusting plate 1, and protruding rods 12 are fixedly connected to the surface of the sliding rods 11.

[0030] The surface of the slide rod 11 is slidably connected to the support base 13, and the surface of the support base 13 is provided with a circular groove 14.

[0031] The inner wall of the circular groove 14 is provided with an embedded groove 15. The slide rod 11 is slidably connected to the inside of the circular groove 14. The embedded groove 15 provides sliding space for the protruding rod 12. When the slide rod 11 slides in the circular groove 14, the protruding rod 12 slides in the embedded groove 15. Through the cooperation between the protruding rod 12 and the embedded groove 15, the sliding position of the slide rod 11 is restricted, thereby ensuring the accuracy and stability of the movement of the adjusting plate 1 on the support base 13.

[0032] The protruding rod 12 is slidably connected to the inside of the recessed groove 15.

[0033] A drive motor 16 is fixedly installed inside the support base 13. The output end of the drive motor 16 is fixedly connected to the lower surface of the adjustment plate 1. The rotation of the drive motor 16 drives the adjustment plate 1 to rotate, thereby realizing the angle adjustment of the components above the adjustment plate 1.

[0034] The implementation principle of the alignment device for a visual inspection equipment for home appliance parts in this application embodiment is as follows: First, the operator starts the negative pressure pump 7. The negative pressure pump 7 generates negative pressure through the negative pressure suction cup 8 at its input end, thereby adsorbing and fixing the parts to be inspected. After the parts are adsorbed and fixed, the operator needs to adjust the position of the parts according to the position of the inspection equipment. At this time, the operator pulls the lever 905. The lever 905 drives the compression plate 903 to retract. The compression plate 903 will compress the return spring 902 and drive the locking pin 904 to move from the positioning groove 1 on the surface of the operating handle 6. When the lever 6 is disengaged from the control handle 0, it is unlocked, allowing the operator to rotate it normally. Rotation of the lever 6 drives the lead screw 5 to rotate. Since the lead screw 5 is threadedly connected to the sliding block 3, the sliding block 3 and the protective box 4 move linearly along the limiting groove 2. The components fixed by the negative pressure suction cup 8 above the protective box 4 also move accordingly, thus adjusting their positions. Once the components are in the correct position, the operator slowly releases the tension on the pull rod 905. Under the reset action of the return spring 902, the locking pin 904 re-inserts into the lever 6. The positioning groove 10 on the surface restricts the rotation of the operating handle 6, ensuring that the adjusted part position remains stable. Furthermore, if the angle of the component needs to be adjusted, the drive motor 16 inside the support base 13 will start, its output end fixedly connected to the lower surface of the adjustment plate 1. The rotation of the drive motor 16 drives the adjustment plate 1 to rotate, thereby adjusting the angle of the component above the adjustment plate 1. Several sliding rods 11 are fixedly connected to the lower surface of the adjustment plate 1. A protruding rod 12 is fixedly connected to the surface of each sliding rod 11, and a support rod is slidably connected to the surface of each sliding rod 11. The support base 13 has a circular groove 14 on its surface and an embedded groove 15 on its inner wall. The slide rod 11 is slidably connected to the inside of the circular groove 14. The embedded groove 15 provides sliding space for the protruding rod 12. When the slide rod 11 slides in the circular groove 14, the protruding rod 12 slides in the embedded groove 15. The cooperation between the protruding rod 12 and the embedded groove 15 restricts the sliding position of the slide rod 11, thereby ensuring the accuracy and stability of the movement of the adjusting plate 1 on the support base 13, and thus ensuring the accuracy of the component angle adjustment.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
