Description

Technical Field

[0001] This utility model belongs to the field of visual inspection technology, and more specifically, it relates to a visual inspection device for an assembly line. Background Technology

[0002] Visual inspection is the use of machines to replace human eyes for measurement and judgment. Visual inspection refers to the process of converting the captured target into an image signal through machine vision products, transmitting it to a dedicated image processing system, and converting it into a digital signal based on pixel distribution, brightness, color and other information. The image system performs various operations on these signals to extract the features of the target, and then controls the operation of the equipment on site based on the judgment results.

[0003] While existing testing equipment can remove dust from parts before testing, it cannot perform multiple dust removal processes or expand the dust removal range and effect, ultimately affecting the testing accuracy. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a production line visual inspection device. This device solves the problem that while existing inspection equipment can remove dust from parts before inspection, it cannot achieve multiple dust removal processes or expand the dust removal range and effect, ultimately affecting the inspection accuracy.

[0005] The purpose and effectiveness of this utility model's assembly line visual inspection equipment are achieved through the following specific technical means:

[0006] A visual inspection device for an assembly line includes a base; a part is placed on the top of the base, and a concave frame is fixed to the top of the base. Two second guide rods slide on the frame, and the right side ends of the two second guide rods are welded to a mounting frame. The mounting frame has a concave structure, and an air jet pipe rotates on the mounting frame. The air jet pipe is connected to an external air supply pump through a rotary joint. A second hydraulic cylinder is fixed to the right end face of the frame, and the extended end of the second hydraulic cylinder is fixed to the mounting frame.

[0007] Furthermore, the lower part of the outer wall of the jet pipe is provided with spray holes in a fan-shaped array.

[0008] Furthermore, a gear is welded onto the jet pipe, and a toothed rack is welded onto the top surface of the base, with the gear meshing with the toothed rack.

[0009] Furthermore, the second guide rod, mounting bracket, jet pipe, nozzle, gear, gear rack, and second hydraulic cylinder together constitute the second cleaning part; the first cleaning part is installed on the frame, which consists of a base block, a sponge block, a connecting block, a first guide rod, a pushing block, and a first hydraulic cylinder. A rectangular block-shaped base block is fixed inside the frame, and a sponge block is attached to the bottom surface of the base block. The bottom surface of the sponge block is lower than the top surface of the part.

[0010] Furthermore, a connecting block is fixed to the top surface of the base, and two first guide rods slide on the connecting block. The right side end of each of the two first guide rods is welded to the push block. The push block is located on the left side of the part. A first hydraulic cylinder is fixed to the right end face of the connecting block, and the extended end of the first hydraulic cylinder is fixed to the push block.

[0011] Furthermore, a groove with a V-shaped structure is provided on the right end face of the push block.

[0012] Furthermore, an industrial camera is fixed to the top surface of the base. The industrial camera is electrically connected to the detection system of the external device and is located below and behind the jet pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In terms of cleaning function, the second cleaning section is particularly noteworthy. A fan-shaped array of nozzles is positioned on the lower outer wall of the jet pipe, enabling more efficient and extensive cleaning of dust from parts during airflow. As the mounting bracket moves the jet pipe left and right, the meshing of gears and toothed drives the jet pipe to rotate reciprocally, further expanding the cleaning range and improving the cleaning effect. Simultaneously, a second hydraulic cylinder drives the mounting bracket and jet pipe to move back and forth, further increasing the cleaning range of the parts.

[0015] The first cleaning section is equally practical. The sponge attached to the bottom surface of the base block can clean the dust on the top of the part when it is moved to this location. The V-shaped groove on the right end of the push block ensures that the part is centered when it is pushed, thus ensuring the accuracy of subsequent visual inspection.

[0016] The equipment features an ingenious design in its inspection process. First, a hydraulic cylinder drives a pusher block to move the part below the air jet pipe. After dust removal by the air jet pipe, an industrial camera samples the part and transmits the image to the inspection system. This entire process seamlessly integrates cleaning and inspection, effectively removing dust from the part's surface and preventing impurities from interfering with the inspection results. Furthermore, precise cleaning and pushing operations ensure the accuracy and reliability of visual inspection, thus improving the efficiency and quality of part inspection.

[0028] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0029] This utility model provides a visual inspection device for an assembly line, including a base 1; a part 5 is placed on the top of the base 1, and a concave frame 2 is fixed to the top of the base 1. Two second guide rods 401 slide on the frame 2, and the right side ends of the two second guide rods 401 are welded to a mounting frame 402. The mounting frame 402 is a concave structure, and an air jet pipe 403 rotates on the mounting frame 402. The air jet pipe 403 is connected to an external air supply pump through a rotating joint. A second hydraulic cylinder 407 is fixed to the right end face of the frame 2, and the extended end of the second hydraulic cylinder 407 is fixed to the mounting frame 402. During air jet cleaning, the second hydraulic cylinder 407 is driven to reciprocate and extend, and the second hydraulic cylinder 407 drives the mounting frame 402 and the air jet pipe 403 to move back and forth, which can improve the cleaning range and cleaning effect of the part 5.

[0030] Among them, the lower part of the outer wall of the jet pipe 403 has spray holes 404 arranged in a fan-shaped array. During gas dust removal, the spray holes 404 arranged in a fan-shaped array can better clean the dust on the part 5, with a wide cleaning range and high efficiency.

[0031] A gear 405 is welded onto the jet pipe 403, and a toothed rack 406 is welded onto the top surface of the base 1. The gear 405 meshes with the toothed rack 406. When the mounting bracket 402 drives the jet pipe 403 to move left and right, the reciprocating rotation of the jet pipe 403 can be achieved through the meshing transmission of the gear 405 and the toothed rack 406. The reciprocating rotation of the jet pipe 403 can expand the cleaning range of the part 5 and improve the cleaning effect of the part 5.

[0032] The second cleaning part 4 is composed of the second guide rod 401, the mounting bracket 402, the jet pipe 403, the spray hole 404, the gear 405, the gear rack 406, and the second hydraulic cylinder 407. The first cleaning part 3 is installed on the frame 2. The first cleaning part 3 is composed of the base block 301, the sponge block 302, the connecting block 303, the first guide rod 304, the pushing block 305, and the first hydraulic cylinder 306. A rectangular block-shaped base block 301 is fixed inside the frame 2. A sponge block 302 is attached to the bottom surface of the base block 301. The bottom surface of the sponge block 302 is lower than the top surface of the part 5. When the part 5 moves to the sponge block 302, the dust on the top of the part 5 can be cleaned through the sponge block 302.

[0033] The base 1 has a connecting block 303 fixed on its top surface. Two first guide rods 304 slide on the connecting block 303. The right side end of each of the two first guide rods 304 is welded to a push block 305. The push block 305 is located on the left side of the part 5. A first hydraulic cylinder 306 is fixed on the right end of the connecting block 303. The extended end of the first hydraulic cylinder 306 is fixed on the push block 305. When cleaning the surface of the part 5, the first hydraulic cylinder 306 is driven to extend. The first hydraulic cylinder 306 drives the push block 305 to move to the right. The push block 305 can push the part 5 to the sponge block 302 to complete the cleaning.

[0034] An industrial camera 6 is fixed to the top surface of the base 1. The industrial camera 6 is electrically connected to the external detection system. The industrial camera 6 is located below and behind the jet pipe 403. During use, the first hydraulic cylinder 306 is extended, and the part 5 is pushed to the position below the jet pipe 403 by the push block 305. The part 5 is dusted by the jet pipe 403, and then the image of the part 5 is sampled by the industrial camera 6 and then transported to the detection system for detection.

[0035] Example 2: Based on Example 1, a groove is provided on the right end face of the push block 305. The groove has a V-shaped structure. When the push block 305 pushes the part 5 to the right, the V-shaped groove can ensure that the part 5 is centered, thereby ensuring the accuracy of subsequent visual inspection.

[0036] Working principle: The robotic arm places part 5 to the right of the push block 305, drives the first hydraulic cylinder 306 to extend, and the first hydraulic cylinder 306 drives the push block 305 to move to the right. The push block 305 pushes part 5 to the sponge block 302 for initial cleaning. The first hydraulic cylinder 306 is then driven to extend, and the push block 305 pushes part 5 to a position below the jet pipe 403. The jet pipe 403 removes dust from part 5. During the gas dust removal process, the second hydraulic cylinder 407 is driven to reciprocate, and the second hydraulic cylinder 407 drives the mounting frame 402 and the jet pipe 403 to move back and forth, achieving reciprocating dust removal. At the same time, when the mounting frame 402 drives the jet pipe 403 to move left and right, the gear 405 and the gear rack 406 mesh to achieve the reciprocating rotation of the jet pipe 403. The reciprocating rotation of the jet pipe 403 achieves further dust removal. The industrial camera 6 samples the image of part 5 and then sends it to the detection system for inspection.
