Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a sheet metal edge banding defect detection machine. Background Technology

[0002] In the field of sheet metal processing, the quality of edge banding is crucial, affecting not only the aesthetics of the sheet metal but also its durability and lifespan. Traditional methods for detecting defects in sheet metal edge banding mainly rely on manual visual inspection. This method is inefficient and easily influenced by the subjective factors of the inspectors, leading to inaccurate results and a high rate of missed detections.

[0003] While some vision-based edge banding inspection equipment for sheet metal has emerged with the development of automation technology, most of these devices can only inspect the edge banding in a single direction, failing to achieve omnidirectional, surround-like inspection. This makes it difficult to accurately identify edge banding defects located at different angles. Furthermore, during sheet metal processing and transportation, dust easily accumulates on the edges, interfering with the imaging of the vision inspection camera and affecting the judgment of edge banding defects. Most existing inspection equipment lacks effective dust removal devices, resulting in poor inspection performance.

[0004] Therefore, this application provides a board edge banding defect detection machine to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a board edge banding defect detection machine to solve the problems of low efficiency, strong subjectivity, and high missed detection rate of manual inspection in the prior art, as well as the inability of some existing automated equipment to achieve all-round surround inspection and the lack of effective dust removal devices that cause imaging interference.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A board edge banding defect detection machine includes a base, an inspection table for placing the board is rotatably mounted on the upper end surface of the base, and a positioning mechanism is provided above the inspection table.

[0008] A side plate is fixed to one side of the upper end face of the base. A movable frame that can be horizontally displaced is provided on the side of the side plate facing the detection table. A sliding seat that can be horizontally displaced is provided on the side of the movable frame facing the detection table. A vision camera is fixed on the sliding seat.

[0009] An air box is fixed around the outer surface of the sliding seat, and multiple nozzles are evenly fixed on the side of the air box facing the testing platform.

[0010] Optionally, a top plate inclined toward the testing table is fixed to the top of the side plate, and a supplementary light is fixed to the lower end surface of the top plate.

[0011] Optionally, a cylinder is fixed to the side of the side plate away from the testing table. The shaft of the cylinder passes horizontally through the middle of the side plate and is fixed to the middle of the movable frame, thereby driving the horizontal lateral displacement of the movable frame.

[0012] Optionally, the end of the sliding seat slides against the side of the movable frame facing the testing table, and a horizontal screw is rotatably mounted on the side of the movable frame facing the testing table. The screw thread passes through the end of the sliding seat, thereby driving the horizontal longitudinal displacement of the sliding seat.

[0013] Optionally, one end of the screw extends beyond the end of the movable frame and is fitted with a second motor.

[0014] Optionally, a blower is fixed to the side of the side plate away from the testing platform, and a hose is connected to the side of the air box. One end of the hose is connected to multiple nozzles through the inner cavity of the air box, and the other end is connected to the output end of the blower.

[0015] Optionally, a first motor is fitted to the bottom of the testing platform. The first motor is fixed inside the base, and the shaft of the first motor is fixed to the middle of the lower end face of the testing platform, thereby forming a rotational drive for the testing platform.

[0016] Optionally, a fixing frame is fixed to the upper edge of the testing table, the top of the fixing frame extends horizontally to the top of the testing table, and a vertical positioning rod is threaded through it. A horizontal abutment plate for abutting the plate is fixed to the lower end of the positioning rod.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, by setting up a rotatable inspection platform and cooperating with a vision camera, the inspection platform can drive the board to rotate, allowing the vision camera to perform a circumferential visual inspection of the board edge banding, which helps to improve the efficiency of defect detection of the board edge banding.

[0019] In the above solution, thanks to the air box surrounding the sliding seat used to fix the vision camera, the nozzles on the air box can blow air to remove dust from the edge sealing position of the board to be inspected on the inspection table, thereby avoiding the dust adsorbed on the edge of the board from affecting the edge sealing inspection results and improving the inspection effect of the board edge sealing.

[0020] In summary, this device can not only perform efficient circumferential edge banding inspection on the board material, but also blow air to remove dust from the board edges during inspection, further ensuring the accuracy of the edge banding inspection results, and the overall performance is good.

[0032] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0033] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0034] like Figures 1-4As shown, this embodiment of the present invention provides a sheet metal edge banding defect inspection machine, including a base 1. An inspection table 2 for placing the sheet metal is rotatably mounted on the upper surface of the base 1. The upper surface of the inspection table 2 is finely polished, resulting in a smooth and flat surface to reduce wear on the sheet metal. A first motor 203 is fitted to the bottom of the inspection table 2. The first motor 203 is fixed inside the base 1, and its shaft is fixed to the center of the lower surface of the inspection table 2. The operation of the first motor 203 drives the rotation of the inspection table 2, allowing the sheet metal placed on it to rotate for subsequent surround inspection. Specifically, the first motor 203 is a high-precision servo motor, whose speed can be precisely controlled, enabling the inspection table 2 to rotate at a uniform and slow speed, ensuring the stability of visual inspection.

[0035] A fixing frame 201 is fixed to the upper edge of the testing table 2. The fixing frame 201 is made of high-strength aluminum alloy, which is lightweight and strong. The top of the fixing frame 201 extends horizontally to the top of the testing table 2, and a vertical positioning rod 202 is threaded through it. A horizontal abutment plate 2021 for abutting the plate is fixed to the lower end of the positioning rod 202. A rubber pad is attached to the lower surface of the horizontal abutment plate 2021. Therefore, by rotating the positioning rod 202, the horizontal abutment plate can be moved downward to abut the plate. The rubber pad can increase the friction between the plate and the plate, prevent the plate from moving during the testing process, and avoid damage to the plate by the horizontal abutment plate.

[0036] Meanwhile, a side plate 101 is fixed to one side of the upper end face of the base 1, and a movable frame 4 capable of horizontal lateral displacement is provided on the side of the side plate 101 facing the inspection table 2. A cylinder 3 is fixed to the side plate 101 away from the inspection table 2. The cylinder 3 is fixed to the side plate 101 by a cylinder bracket 301. The cylinder bracket 301 is fixed to the side plate 101 and the cylinder 3 by welding to ensure the stability of the connection. The shaft of the cylinder 3 passes horizontally through the middle of the side plate 101 and is fixed to the middle of the movable frame 4. When the cylinder 3 is activated, its shaft will drive the movable frame 4 to perform horizontal lateral displacement, thereby adjusting the lateral position of the movable frame 4 relative to the inspection table 2.

[0037] A sliding seat 5, capable of horizontal and longitudinal displacement, is provided on the side of the movable frame 4 facing the inspection table 2. The end of the sliding seat 5 slides against the side of the movable frame 4 facing the inspection table 2. A horizontal screw 401, made of high-precision ball screw, is rotatably mounted on the side of the movable frame 4 facing the inspection table 2. The screw 401 is threaded through the end of the sliding seat 5, and one end of the screw 401 extends out of the end of the movable frame 4 and is coupled with a second motor 402. The second motor 402 can be fixed to the end of the movable frame 4 via a motor mount. When the second motor 402 is started, it drives the screw 401 to rotate. Since the screw 401 is threadedly connected to the sliding seat 5, and the end of the sliding seat 5 slides against the movable frame 4, the rotation of the screw 401 causes the sliding seat 5 to move horizontally and longitudinally along the screw 401, thereby adjusting the longitudinal position of the sliding seat 5 relative to the inspection table 2.

[0038] A vision camera 6 is fixed on the sliding seat 5. The vision camera 6 is a high-resolution industrial camera with a lens that features high definition and low distortion, enabling it to capture clear images of the sheet metal edge banding. The vision camera 6 is fixed inside the sliding seat 5 by a camera bracket. Therefore, by the horizontal lateral displacement of the movable frame 4 and the horizontal longitudinal displacement of the sliding seat 5, the vision camera 6 can be adjusted to a suitable position for inspecting the sheet metal edge banding on the inspection table 2.

[0039] An air box 7 is fixedly mounted around the outer surface of the sliding seat 5. Multiple nozzles 701 are evenly fixed on the side of the air box 7 facing the testing platform 2, generating a uniform airflow to effectively blow away dust from the edge sealing area of ​​the board. An air pump 8 is fixed on the side of the side plate 101 away from the testing platform 2. The air pump 8 is fixed to the side plate 101 via an air pump bracket, and a flexible hose 702 is connected to the side of the air box 7. One end of the hose 702 connects to the multiple nozzles 701 through the inner cavity of the air box 7, and the other end connects to the output end of the air pump 8. During the testing process, the air pump 8 is activated, delivering air through the hose 702 into the air box 7, which is then sprayed out by the multiple nozzles 701 on the air box 7 to blow away dust from the edge sealing area of ​​the board to be tested on the testing platform 2. This prevents dust adsorbed on the edge of the board from affecting the edge sealing test results, further improving the testing effect.

[0040] In addition, a top plate 102, inclined towards the inspection table 2, is fixed to the top of the side plate 101. The top plate 102 and the side plate 101 are fixed together by welding to ensure a strong connection. A supplementary light 103 is fixed to the lower end of the top plate 102. The supplementary light 103 uses an LED light source, which has the advantages of high brightness, long life, and energy saving. The supplementary light 103 can provide sufficient light for the vision camera 6 during the inspection process, ensuring that the vision camera 6 can clearly capture the image of the edge of the board, thereby improving the accuracy of the inspection.

[0041] The working principle of the technical solution provided by this utility model is as follows:

[0042] In actual use, the board to be inspected is first placed on the inspection table 2. The horizontal abutment plate 2021 is made to abut against the board by rotating the positioning rod 202, thereby fixing the board in place.

[0043] Then, the first motor 203 is started, causing the inspection table 2 to slowly rotate the board. At the same time, according to the size and position of the board, the cylinder 3 and the second motor 402 are started. The cylinder 3 drives the movable frame 4 to move horizontally, and the second motor 402 drives the screw 401 to rotate, causing the sliding seat 5 to move horizontally, thereby moving the vision camera 6 to a suitable inspection position and ensuring that the vision camera 6 can be accurately aligned with the edge of the board.

[0044] Next, the supplementary light 103 and the air pump 8 are activated. The supplementary light 103 provides sufficient light for the vision camera 6, and the air pump 8 blows air through the nozzles 701 to remove dust from the edge banding area of ​​the board. The vision camera 6 performs a surround-view imaging of the rotating edge banding and transmits the captured images to the subsequent image processing system for analysis, thereby detecting defects in the edge banding. The entire inspection process is efficient and accurate, effectively avoiding dust interference and ensuring the accuracy of the edge banding inspection results, resulting in good overall performance.

[0045] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
