Description

Technical Field

[0001] This utility model relates to the technical field of brass sheet and strip production, specifically to a defective product detection device for brass sheet and strip production. Background Technology

[0002] Copper plate and strip is a general term for copper plates and strips. During the production process, some defective products are often generated. The existing processing method mainly relies on manual removal. However, the method of manual inspection and removal is not only cumbersome, but also easily affected by fatigue. During long working hours, when attention is not focused, some defective products may be missed, thus affecting the quality of subsequent products.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent CN211538637U, published on September 22, 2020) provides a defective product detection device for brass strip production. This device includes a main body, with a defective product collection box placed at the bottom of the inner cavity of the main body. A motor is fixedly installed at the bottom of one side of the main body, and a drive pulley is fixedly sleeved on the output shaft of the motor. This invention supports the top plate with a support rod and a telescopic rod is fixedly installed in the middle of the top plate, allowing the scanner at the bottom of the telescopic rod to be adjusted in position, enhancing the flexibility of the device and making the scanning clearer. Furthermore, when the scanner scans a defective product, an electrical signal is transmitted to a hydraulic push rod, which then activates, pushing the brass strip a certain distance, causing it to become unbalanced and fall into the defective product collection box, thus achieving the purpose of automatically removing defective products.

[0004] Existing technology uses active belt pulleys to transport brass strips for inspection. However, during operation, the brass strip is prone to slipping on the belt pulley structure, resulting in unstable transport speed. This may cause the scanner to miss some defective products and produce displacement errors, thus affecting the rejection effect.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing defective product detection device used in brass strip production. Therefore, we propose that the defective product detection device for brass strip production can effectively solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a defective product detection device for brass strip production, in order to solve the problem mentioned in the background art that the current market uses active belt pulleys to transport brass strips for inspection, but during operation, the brass strip is prone to slipping on the belt pulley structure, resulting in unstable conveying speed, which may cause the scanner to miss some defective products and produce displacement errors, thereby affecting the rejection effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a defective product detection device for brass strip production, comprising a detection box, a support on the detection box, and detection components for defective product detection mounted on the support. The detection box has a rotating groove, and a limiting plate is installed inside the rotating groove. Suction seats are symmetrically arranged on the detection box, with a suction pipe installed on one side of each suction seat and a suction hole on the other side. A suction groove is formed on the side end of the limiting plate, and the suction groove is matched to the suction hole, and the suction groove communicates with the internal cavity of the limiting plate. A through hole is formed on the limiting plate, and the through hole communicates with the internal cavity of the limiting plate. Limiting components for clamping brass strips are symmetrically arranged on the limiting plate.

[0008] Preferably, a first motor is installed inside the detection box, and a rotating shaft is connected to the output end of the first motor. The rotating shaft passes through and is connected inside the limiting plate, and the limiting plate is symmetrically arranged.

[0009] Preferably, the testing box is equipped with a collection box for receiving defective products. The bottom of the collection box is equipped with symmetrically arranged sliders. The bottom of the testing box is symmetrically provided with sliding grooves, and the sliders are slidably connected inside the sliding grooves.

[0010] Preferably, a second motor is installed inside the bracket on the testing box, the output end of the second motor is connected to a rotating shaft, and a connecting rope is wound around the outside of the rotating shaft.

[0011] Preferably, a movable block is connected to the end of the connecting rope, and a guide rod is connected through the movable block.

[0012] Preferably, a spring is sleeved on the outside of the guide rod, a storage box is installed inside the bracket on the detection box, the guide rod is located inside the storage box, and the storage boxes are symmetrically arranged.

[0013] Preferably, a cleaning block is provided below the moving block, and the cleaning block is moved to the surface of the test piece by the moving block.

[0014] Preferably, gears are mounted on the outer side of the rotating shaft, and the gears are arranged symmetrically.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This defective product inspection device for brass strip production places the brass strip to be inspected on a limiting plate. Air is drawn in through holes on the surface of the limiting plate, generating negative pressure to adsorb the brass strip onto the surface of the limiting plate. This achieves stable and rapid fixation of the brass strip, avoiding inaccurate inspection results due to strip movement during the inspection process, effectively improving inspection accuracy. It is applicable to brass strips of different specifications, enhancing the equipment's versatility and reducing the problem of missed defective products due to unstable brass strip conveying speed. The specific details are as follows:

[0016] The through holes on the surface of the limiting plate allow for air intake, which causes the brass strip to adhere to the surface of the limiting plate, achieving stable and rapid fixation of the brass strip. This not only avoids inaccurate test results due to strip movement during the testing process, but also reduces the problem of missing defective products due to unstable brass strip conveying speed, thus improving the accuracy of the testing operation.

[0017] When a defective brass strip is detected, the rotating shaft drives the limiting plate to rotate, facilitating the transfer of the defective product into the inspection box. This achieves automatic switching between the inspection station and the defective product handling station, eliminating the need for manual transfer of the brass strip and reducing labor and time costs.

[0018] When the limiting plate rotates, the air intake groove on its side leaves the surface of the air intake hole, opening the limiting part on the side of the defective product. Under the action of gravity, the defective product falls into the collection box. The collection box not only makes it convenient for staff to quickly clean up the defective products, but also facilitates the subsequent analysis and processing of the defective products.

[0019] The moving block drives the cleaning block to move to the surface of the test piece for cleaning. The second motor rotates in the opposite direction to loosen the connecting rope, causing the moving block to rebound through the spring and lift the cleaning block off the surface of the test piece. This reduces the problem of reduced detection accuracy caused by dust on the outer surface of the test piece.

[0020] The output of the second motor drives the rotating shaft to rotate, which facilitates the winding of the outer connecting rope. The gears on the outer side of the rotating shaft driven by the second motor are also symmetrically arranged, which facilitates the movement of the cleaning blocks by the gears and the above-mentioned structure. This allows the symmetrically arranged cleaning blocks to move towards or relative to each other, making it easier to clean the test pieces and improving the automation level and operating efficiency of the equipment.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: In this example, the suction hole on the inner side of the suction seat 4 cooperates with the suction groove on the side of the limiting plate 3, allowing the through hole 6 on the surface of the limiting plate 3 to perform suction operation, thereby achieving stable and rapid fixation of the brass strip and avoiding inaccurate test results due to strip movement during the testing process. Figures 1-4The technical solution shown includes a detection box 1 with a support frame and a detection component 2 for defective product detection mounted on the support frame. The detection box 1 has a rotating groove with a limiting plate 3 installed inside. The detection box 1 has symmetrically arranged suction seats 4, with a suction pipe on one side and a suction hole on the other side. The limiting plate 3 has a suction groove on its side, which is matched to the suction hole and communicates with the internal cavity of the limiting plate 3. The limiting plate 3 has a through hole 6, which communicates with the internal cavity of the limiting plate 3. The limiting plate 3 also has symmetrically arranged limiting components 5 for clamping brass strips. When the brass strip to be tested is placed on the limiting plate 3, the suction seat 4 is connected to an external suction structure via a side suction pipe, facilitating the connection between the suction hole inside the suction seat 4 and the suction groove on the side of the limiting plate 3, allowing for external suction. The suction structure adsorbs the gas inside the cavity of the limiting plate 3, allowing the through holes 6 on the surface of the limiting plate 3 to perform suction operations. This generates negative pressure, adsorbing the brass strip onto the surface of the limiting plate 3, achieving stable and rapid fixation of the brass strip. This avoids inaccurate test results due to strip movement during the testing process, effectively improving test accuracy. Furthermore, this adsorption method is applicable to brass strips of different specifications, enhancing the versatility of the equipment. The limiting plate 3 surface, through the movement of the limiting component 5, clamps both sides of the brass strip, further enhancing the fixation effect and ensuring that the strip will not shift or shake during the testing process. At this time, the testing component 2 on the bracket of the testing box 1 is opened to test the limited brass strip. This reduces the problem of the testing component 2 missing defective products due to unstable brass strip conveying speed. Stable fixation conditions provide a reliable testing basis for the testing component 2, improving the accuracy of the testing operation.

[0031] Example 2: In this example, the rotating shaft 8 drives the limiting plate 3 to rotate, facilitating the transfer of defective products into the testing box 1. Under gravity, the defective products fall into the collection box 9, as detailed below. Figures 1-5As shown, a first motor 7 is installed inside the inspection box 1. The output end of the first motor 7 is connected to a rotating shaft 8, which passes through and is connected inside a limiting plate 3. The limiting plate 3 is symmetrically arranged. A collection box 9 for receiving defective products is installed inside the inspection box 1. Symmetrically arranged sliders 10 are installed at the bottom of the collection box 9. A sliding groove 11 is symmetrically opened at the bottom of the inspection box 1, and the sliders 10 are slidably connected inside the sliding groove 11. When the first motor 7 is turned on, its output end drives the rotating shaft 8 to rotate, causing the rotating shaft 8 to rotate the limiting plate 3. When the limiting plate 3 rotates, the suction groove on its side leaves the surface of the suction hole. At this time, the brass strip is only limited by the limiting member 5 on the surface of the limiting plate 3. When a defective brass strip is detected, it is... The rotating shaft 8 drives the limiting plate 3 to rotate, facilitating the transfer of defective products into the inspection box 1. At this time, the limiting plate 3 on the surface of the inspection box 1 facilitates further inspection, thereby realizing the automatic switching between the inspection station and the defective product handling station, improving inspection efficiency. The entire process eliminates the need for manual transfer of brass strips, reducing labor and time costs. Opening the limiting part 5 on the side of the defective product allows it to fall into the collection box 9 under the action of gravity. The collection box 9 moves within the slide groove 11 of the inspection box 1 via the slider 10, facilitating its removal from the inspection box 1. This not only makes it easier for staff to quickly clean up defective products and maintain a clean working environment, but also facilitates subsequent analysis and processing of defective products, contributing to the improvement of production processes.

[0032] Example 3: In this example, the symmetrically arranged cleaning blocks 19 move towards or relative to each other, facilitating the cleaning operation of the test piece 2, improving the automation level and operating efficiency of the equipment, as detailed below. Figure 1 , Figure 6 and Figure 7As shown, a second motor 12 is installed inside the bracket on the testing box 1. The output end of the second motor 12 is connected to a rotating shaft 13. A connecting rope 14 is wound around the outside of the rotating shaft 13. A moving block 15 is connected to the end of the connecting rope 14. A guide rod 16 is connected through the moving block 15. A spring 17 is sleeved on the outside of the guide rod 16. A storage box 18 is installed inside the bracket on the testing box 1. The guide rod 16 is located inside the storage box 18. The storage box 18 is symmetrically arranged. A cleaning block 19 is set below the moving block 15. The cleaning block 19 moves to the surface of the testing piece 2 via the moving block 15. Gears 20 are installed on the outside of the rotating shaft 13. The gears 20 are symmetrically arranged. When the second motor 12 is turned on, the output end of the second motor 12 drives the rotating shaft 13 to rotate, which facilitates the rotating shaft 13 to drive the outer connecting rope 14 to wind, which facilitates the tightening of the connecting rope 14 and drives the moving block 15 at its end to move on the guide rod 16. At this time, the spring at the side of the moving block 15... When the spring 17 is stretched, the moving block 15 drives the cleaning block 19 to move, making it easier for the cleaning block 19 to move to the surface of the test piece 2 for cleaning. The second motor 12 rotates in the opposite direction, causing the connecting rope 14 to loosen. At this time, the moving block 15 rebounds through the spring 17, causing the cleaning block 19 to leave the surface of the test piece 2. This reduces the problem of reduced detection accuracy caused by dust on the outer surface of the test piece 2. The moving blocks 15 located inside the storage box 18 are symmetrically arranged, and the gears 20 on the outer side of the rotating shaft 13 driven by the second motor 12 are also symmetrically arranged. Therefore, the gears 20 and the above-mentioned structure facilitate the movement of the cleaning blocks 19, so that the symmetrically arranged cleaning blocks 19 can move towards or relative to each other, making it convenient to clean the test piece 2. The entire cleaning process does not require manual intervention, further improving the automation level and operating efficiency of the equipment. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
