Description

Technical Field

[0001] The present invention relates to the field of visual inspection technology, and in particular to a multifunctional computer visual inspection device. Background Art

[0002] Computer vision inspection devices are devices that use computer vision technology to achieve automated inspection. Computer vision is a technology that enables computers to extract information from images or multidimensional data. It is widely used in many fields such as industry, medicine and agriculture.

[0003] Through double-sided visual inspection of the target workpiece, images can be captured from two different angles, and the position and shape of the object in three-dimensional space can be calculated by analyzing the parallax in these images. This is especially important for workpieces that need to accurately measure the size and shape of the object. The automated double-sided inspection system can work quickly and continuously without being affected by manual fatigue, thereby improving production efficiency. In the prior art, in order to achieve double-sided inspection of the target, most of the time, after the visual inspection camera completes the image capture of one side of the target end face, a mechanical device is used to automatically flip the product so that the other side of the target workpiece faces the visual inspection camera, completing the double-sided inspection of the target product. This inspection method has the problem of low inspection efficiency due to the use of a method of inspecting the target face by face.

[0004] Moreover, since dust and other impurities often adhere to the target panel, they may interfere with the image acquisition of the visual camera, resulting in a decrease in image quality and affecting subsequent image processing and analysis. The existing technology usually performs dust blowing operations on horizontally placed targets, which makes it difficult to effectively remove impurities from the panel.

[0005] Based on the above-mentioned defects, a multifunctional computer vision detection device is provided. Summary of the invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-5 The present invention provides a technical solution: a multifunctional computer vision detection device, comprising a body 1 and a detection chamber 2, wherein the detection chamber 2 is rotatably connected to a shaft 7, and the outer side of the shaft 7 is slidably connected to a rotary seat 3, and a clamping mechanism is arranged on the rotary seat 3. The clamping mechanism comprises a bidirectional telescopic rod 4 mounted on the rotary seat 3, and a clamping arm 6 for clamping a target is fixed at the free end of the bidirectional telescopic rod 4, and a lateral driving mechanism 32 for controlling the rotary seat 3 to slide along the shaft 7 is arranged in the body 1.

[0033] The bidirectional telescopic rod 4 is a bidirectional hydraulic cylinder of the prior art, which is a hydraulic actuator capable of bidirectional push-pull functions. The bidirectional telescopic rod 4 controls the distance between the two clamping arms 6 to achieve the picking and placing of the target product. The lateral drive mechanism 32 is also composed of an existing screw and a threaded sleeve, wherein the rotation of the screw is controlled by a motor installed on the body 1, and a disc is fixed on the rotary seat 3, wherein a groove is formed in the threaded sleeve to cooperate with the rotation of the disc.

[0034] The shaft 7 is provided with a spline to slide with the rotary seat 3, so that the rotary seat 3 can slide along the shaft 7 when rotating with the shaft 7. When the clamp arm 6 is used to clamp the target placed horizontally in the inspection bin 2, the shaft 7 is controlled to drive the rotary seat 3 to rotate, so that the target product is placed vertically, which is conducive to the subsequent inspection equipment to perform synchronous double-sided inspection on the target product. In the inspection process, the lateral drive mechanism 32 drives the rotary seat 3 to move back and forth in the horizontal direction, so that the inspection equipment can fully obtain the end surface information of the target product.

[0035] A square shell 25 is fixedly installed on the inner top of the detection chamber 2 through an air pipe 27, and multiple nozzles 26 are installed on the front and rear sides of the square shell 25. An air storage cavity connected to the air pipe 27 is formed on the inner top of the body 1, and a plug disc 28 is slidably connected to the inside of the air storage cavity.

[0036] When the target product rotates to a vertical state, the plug disc 28 is controlled to move downward along the air storage chamber, so that the gas in the air storage chamber enters the square shell 25 through the air pipe 27, and then the nozzle 26 installed on the square shell 25 acts on the surface of the target product in a vertical state, thereby facilitating the efficient removal of dust and impurities adhering to the surface of the product.

[0037] The outer side of the air pipe 27 is rotatably connected to a rotating frame 21, and the inner side of the rotating frame 21 is slidably connected to two bending arms 22, and a CCD camera 24 is vertically slidably installed on the opposite side of the two bending arms 22. A shell cover 11 is installed on the upper end of the body 1, and a second gear disc 19 is rotatably connected in the shell cover 11. A connecting rod 20 is fixed between the second gear disc 19 and the rotating frame 21. A sliding groove 101 is formed in the body 1 to cooperate with the connecting rod 20 to slide through. A driving member for controlling the shaft rod 7 and the second gear disc 19 to rotate successively is provided in the shell cover 11. A guide member is provided in the shell cover 11. When the second gear disc 19 rotates, the guide member controls the plug disc 28 to move vertically along the air storage chamber.

[0038] The CCD camera 24 is an existing technology used in visual detection and is a digital imaging device that converts light signals into electrical signals.

[0039] The bending arm 22 is equipped with a linear motor to control the CCD camera 24 to slide vertically along the bending arm 22, so as to obtain the surface information of the target product. The connecting rod 20 deviates from the center of the second toothed disc 19 and passes through the body 1 downward and is fixed to the rotating frame 21. This design allows the connecting rod 20 to avoid the gas storage cavity. By setting a larger gas storage cavity, the downward pressure of the plug disc 28 can provide sufficient gas to meet the effective cleaning of the end surface of the target product by the nozzle 26.

[0040] When the product is lifted up to a vertical position along with the rotating seat 3, the rotation of the second gear disc 19 is controlled to drive the rotating frame 21 fixed to the connecting rod 20 to drive the bending arm 22 to rotate, so that the two CCD cameras 24 slidably mounted on the bending arm 22 face the two inspection surfaces of the target product, thereby satisfying the synchronous inspection of the inspection surfaces at both ends of the product, thereby improving the double-sided inspection efficiency of the product.

[0041] Specifically, Figure 3 As shown, a water storage chamber 5 communicating with the detection chamber 2 is formed inside the machine body 1 .

[0042] Liquid is accumulated in the water storage tank 5, and a channel for the liquid in the water storage tank 5 to enter and exit is provided on the side of the body 1. Impurities blown off the product will fall into the water storage tank 5, and the impurities blown off will be attached and collected by the liquid in the water storage tank 5, thereby avoiding the phenomenon of dust and other impurities floating around during the air blowing process, which affects the effective cleaning of the product surface.

[0043] Specifically, Figure 2-4 As shown, the driving member includes a rotating shaft 13 and a first toothed disc 17 rotatably connected to the inner side of the housing 11, a pressing assembly driving the rotating shaft 13 and the first toothed disc 17 to rotate successively, and a sprocket transmission mechanism. The sprocket transmission mechanism includes a second wheel disc 10 rotatably connected to the outer side of the housing 11 and coaxially fixed with the rotating shaft 13, a first wheel disc 8 coaxially fixed with the shaft 7 is rotatably connected to the outer side of the detection chamber 2, and a chain 9 is provided on the outer meshing sleeve of the first wheel disc 8 and the second wheel disc 10.

[0044] When visual inspection of the product is required, the operation of the pressing assembly causes the swivel 13 to rotate first, and the second wheel disc 10 coaxially fixed with the swivel 13 will drive the shaft 7 coaxially fixed with the first wheel disc 8 to rotate synchronously through the chain 9, so that the product is clamped by the clamping arm 6 and lifted up with the rotating seat 3. During this process, the first toothed disc 17 remains stationary, and the bending arm 22 will also be stationary relative to the inspection chamber 2, providing space for the vertical lifting of the product. With the operation of the pressing assembly, when the first toothed disc 17 rotates, the swivel 13 will remain stationary, and the second toothed disc 19 meshing with the first toothed disc 17 will drive the rotating frame 21 to rotate through the connecting rod 20, so that the CCD camera 24 rotates with the bending arm 22 toward the inspection end face of the product. During this process, the product will remain in a stable vertical mounting state with the rotating seat 3.

[0045] The compression assembly includes a sleeve 15 which is slidably mounted on the outside of the rotating shaft 13, and a telescopic mechanism 12 which controls the horizontal movement of the sleeve 15 is installed at the inner end of the housing 11. The telescopic mechanism 12 is an existing pneumatic or hydraulic telescopic rod, and the free end of the telescopic mechanism 12 is fixed to the sleeve 15 to control the sleeve 15 to slide along the rotating shaft 13.

[0046] The inner wall of the sliding sleeve 15 is formed with a protrusion 1, the side wall of the rotating shaft 13 is formed with a first slide rail 14 that slides with the protrusion 1, the side end of the sliding sleeve 15 is fixed with a guide rod 16, and the first toothed disc 17 is formed with a slideway 18 that slides with the guide rod 16. The first slide rail 14 is composed of a spiral groove and a linear groove, and the slideway 18 is composed of a transverse groove and an oblique groove. When the protrusion 1 slides along the spiral groove, the guide rod 16 slides along the transverse groove, and when the protrusion 1 slides along the linear groove, the guide rod 16 will slide along the oblique groove.

[0047] When the protrusion 1 slides along the spiral groove, the protrusion drives the rotating shaft 13 to rotate through the compression transmission of the inner wall of the spiral groove. When the protrusion 1 slides along the linear groove, the rotating shaft 13 will remain stationary. The transverse groove is radially distributed relative to the first toothed disc 17. When the guide rod 16 slides along the transverse groove, the first toothed disc 17 remains stationary. The oblique groove is inclined relative to the radial direction of the first toothed disc 17. When the guide rod 16 slides along the oblique groove, the first toothed disc 17 is driven to rotate through the compression transmission of the guide rod 16 on the inner wall of the oblique groove.

[0048] Specifically, Figure 2-4 As shown, the guide member includes a sliding shaft 29 that slides coaxially with the second toothed disc 19, a second protrusion is formed on the inner wall of the second toothed disc 19, and a second slide rail 30 that slides with the second protrusion is formed on the side wall of the sliding shaft 29. A spline rod 31 that slides with the sliding shaft 29 is fixed to the inner top of the housing 11.

[0049] The second slide rail 30 is a spiral groove. When the second toothed disc 19 rotates, the second protrusion fixed on the inner wall of the second toothed disc 19 will slide along the second slide rail 30. The second protrusion presses the inner wall of the second slide rail 30, driving the plug disc 28 fixed to the slide shaft 29 to move downward. The spline rod 31 is slidably connected with the slide shaft 29 to limit the relative rotation of the slide shaft 29, which is conducive to the effective transmission of the second protrusion to the second slide rail 30. Through the coordinated arrangement of this structure, when the rotating frame 21 rotates to adjust the position of the CCD camera 24, the plug disc 28 is pressed down synchronously to blow and clean the product surface, which is conducive to improving the efficiency of product inspection.

[0050] Specifically, Figure 3-5 As shown, a round block 23 is fixedly provided on the top of the bending arm 22, and an arc groove 102 is formed on the inner top of the body 1 to cooperate with the sliding of the round block 23. When the rotating frame 21 rotates, as the round block 23 slides in the arc groove 102, the bending arm 22 will slide along the rotating frame 21.

[0051] When the bending arm 22 rotates with the rotating frame 21, the round block 23 fixed on the bending arm 22 will slide along the arc groove 102. The arc groove 102 compresses and guides the round block 23, so that the bending arm 22 can slide along the rotating frame 21. When the product is lifted up with the rotation of the rotating seat 3, the two bending arms 22 remain away from each other, reserving enough space for the vertical lifting of the product. When the CCD camera 24 rotates toward the detection surface of the product with the rotation of the rotating frame 21, the two bending arms 22 move closer to each other, so that the CCD camera 24 is close to the surface of the product, which is conducive to obtaining product surface information.

[0052] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
