Description

Technical Field

[0001] The utility model relates to the technical field of product appearance detection, in particular to a CCD visual detection and sorting device. Background Art

[0002] In industrial production, CCD vision cameras are often used to take photos of the product's appearance and remove defective products based on the test results. Existing CCD vision inspection equipment is usually equipped with a material transfer mechanism that can clamp the product to facilitate the delivery of the product to the CCD vision camera. However, for some smaller workpieces, the existing material transfer mechanism is difficult to accurately clamp, and the workpiece may even fall accidentally during the delivery process. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a CCD visual inspection and sorting device, which not only ensures the visual inspection of small-sized workpieces, but also avoids the accidental falling of workpieces during transportation.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a CCD visual inspection and sorting equipment, including a workbench installed on a rotating platform, and a loading station, a CCD inspection station, and a unloading station arranged in sequence around the workbench; wherein,

[0005] The unloading station is provided with a plurality of unloading areas arranged along the outer peripheral surface of the work table, each of the unloading areas includes a material collection box and a purge assembly used in conjunction with each other, and the material collection box is provided with a material unloading port connected to the interior thereof on the side facing the work table; the purge assembly includes a mounting plate and a purge needle tube, and the purge needle tube is located above the work table and fixed to the material collection box through the mounting plate; and a spacing is left between the lowest end of the purge assembly and the work table for the product to pass through.

[0006] When gas is introduced into the purge needle tube, the gas can be blown toward the workbench along the purge needle tube to blow the product on the workbench into the corresponding discharge port.

[0007] The beneficial effects of the CCD visual inspection and sorting equipment of the utility model are:

[0008] The products to be inspected are loaded onto the workbench through the loading station, and the workbench is driven to rotate by the rotating platform, so that the products to be inspected on the workbench can be rotated to the CCD inspection station; and the products inspected by the CCD inspection station can be rotated to the unloading station; multiple unloading areas are arranged at the unloading station, so as to classify the products according to the inspection results of the CCD inspection station, and different categories of products can be unloaded separately through multiple unloading areas.

[0009] Exemplarily, the unloading station can be provided with three unloading areas, one of which is used as a good product unloading area to detect qualified product unloading; one is used as a defective product unloading area to detect unqualified product unloading; and the last is used as a pending unloading area to detect abnormal product unloading (that is, the product cannot be detected as qualified or unqualified).

[0010] In the present application, the worktable is driven to rotate by a rotating platform to transport the products to the CCD inspection station in sequence. The products are supported by the worktable throughout the entire process, thereby avoiding the phenomenon of accidental falling caused by insufficient clamping force in the prior art.

[0011] Furthermore, one end of the purge needle tube is provided with a pipe opening for connecting a pipeline, and the other end is gradually inclined downward from away from the material collection box to close to the material collection box. By limiting the direction of the purge needle tube, the purge needle tube can exert an oblique force on the product, which is conducive to the product moving along the workbench toward the unloading port of the material collection box.

[0012] Furthermore, the mounting plate includes a plate body, one end of which is connected to the material collection box body through a fine-tuning assembly, and the other end is provided with a seat body for fixing the purge needle tube. The position between the plate body and the material collection box body can be adjusted by setting the fine-tuning assembly to adjust the position of the purge needle tube on the workbench, so that the purge needle tube can effectively purge the product.

[0013] Furthermore, the fine-tuning component includes at least one waist-shaped long groove formed on the plate body, and a locking member threadedly connected to the aggregate box body is provided through the waist-shaped long groove.

[0014] Furthermore, the side of the material collecting box body facing the workbench is provided with an extension protrusion extending to the bottom of the workbench, and the extension protrusion is connected with the discharge port and the interior of the material collecting box body. The provision of the extension protrusion can prevent the product from getting stuck between the workbench and the material collecting box body when entering the discharge port.

[0015] Furthermore, the loading station is provided with a vibrating loading plate, and the vibrating loading plate is respectively provided with a feed port and a discharge port; the discharge port is provided with a discharge guide rail extending to the top of the work table, and the discharge guide rail is provided with a guide groove for the movement of a single product.

[0016] Furthermore, a stop plate that can cover the guide groove is provided at one end of the discharge guide rail close to the workbench, and the stop plate extends toward the workbench. Since the discharge guide rail is located above the workbench, when the product enters the workbench from the guide groove, the product has a tendency to move downward. Therefore, the setting of the stop plate can prevent the product from flipping when entering the workbench from the guide groove.

[0017] Furthermore, the feed port is connected to a collecting box of one of the unloading areas. The unloading area is the undetermined unloading area. Since the product in the undetermined unloading area is a product with abnormal detection, it is connected to the feed port so that the product can flow back to the vibrating loading plate and be reloaded and tested.

[0018] Furthermore, the discharging guide rail and the worktable are arranged obliquely, so that the product has an oblique initial velocity when entering the worktable, so as to facilitate the synchronous rotation of the product with the worktable.

[0019] Furthermore, a mounting frame is provided on the CCD detection station, and a visual camera located above the workbench is installed on the mounting frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0030] Example

[0031] See attached Figure 1-3 As shown, a CCD visual inspection and sorting device of the utility model comprises a workbench 2 installed on a rotating platform 1, and a loading station 3, a CCD inspection station 4, and a unloading station arranged in sequence around the workbench 2. Among them, the unloading station is provided with a plurality of unloading areas 5 arranged along the outer peripheral surface of the workbench 2, and each unloading area 5 includes a material collection box 51 and a purge assembly 52 for use together. The material collection box 51 is provided with a material unloading port connected to the inside thereof on one side facing the workbench 2; the purge assembly 52 includes a mounting plate 521 and a purge needle 522, and the purge needle 522 is located above the workbench 2 and fixed to the material collection box 51 through the mounting plate 521; and a spacing for the product to pass is left between the lowest end of the purge assembly 52 and the workbench 2. When gas is introduced into the purge needle tube 522 , the gas can be blown toward the workbench 2 along the purge needle tube 522 to blow the product on the workbench 2 into the corresponding discharge port.

[0032] The products to be inspected are loaded onto the workbench 2 through the loading station 3, and the workbench 2 is driven to rotate through the rotating platform 1, so that the products to be inspected on the workbench 2 can be rotated to the CCD inspection station 4; and the products inspected by the CCD inspection station 4 can be rotated to the unloading station; a plurality of unloading areas 5 are arranged at the unloading station, so as to classify the products according to the inspection results of the CCD inspection station 4, and different categories of products can be unloaded separately through the plurality of unloading areas 5.

[0033] Exemplarily, the unloading station can be provided with three unloading areas 5, wherein one unloading area is used as a good product unloading area for detecting the unloading of qualified products; one unloading area is used as a defective product unloading area for detecting the unloading of unqualified products; and the last unloading area is used as a pending unloading area for detecting the unloading of abnormal products (that is, the product cannot be detected as qualified or unqualified).

[0034] During operation, the corresponding unloading area 5 is started according to the detection result of the CCD detection station 4 (qualified product, unqualified product, abnormal product): when the product detection result is that the product is qualified and the product moves to the good product unloading area, the purge component 52 of the good product unloading area is activated to send the product to the corresponding aggregate box 51; when the product detection result is that the product is unqualified and the product moves to the defective product unloading area, the purge component 52 of the defective product unloading area is activated to send the product to the corresponding aggregate box 51; when the product detection result is that the product is abnormal and the product moves to the pending unloading area, the purge component 52 of the pending unloading area is started to send the product to the corresponding aggregate box 51.

[0035] In actual applications, due to abnormal conditions at the loading station 3 or the CCD inspection station 4, the CCD inspection station 4 may be unable to detect the product, resulting in the inspection result being an abnormal product. Therefore, by adding a pending unloading area, this type of product can be unloaded.

[0036] It should be noted that the arrangement order of the good product unloading area, the defective product unloading area, and the pending unloading area can be adjusted according to actual needs, and by limiting the distance between the lowest end of the purge assembly 52 and the work table 2, it can be ensured that the product can smoothly enter any unloading area 5.

[0037] In some embodiments, see Appendix Figure 1-2 As shown, one end of the purge needle tube 522 is provided with a pipe opening for pipeline connection, and the other end is gradually inclined downward from away from the material collection box 51 to close to the material collection box 51. By limiting the direction of the purge needle tube 522, the purge needle tube 522 can exert an oblique force on the product, which is conducive to the product moving along the workbench 2 toward the unloading port of the material collection box 51.

[0038] In some embodiments, the mounting plate 521 includes a plate body, one end of which is connected to the material collecting box 51 through a fine adjustment component, and the other end is provided with a seat body for fixing the purge needle tube 522. Figure 1 As shown, the fine-tuning assembly includes at least one waist-shaped long groove 523 provided on the plate body, and a locking member 524 threadedly connected to the material collection box 51 is provided in the waist-shaped long groove 523. Exemplarily, the locking member 524 is a bolt. The position between the plate body and the material collection box 51 can be adjusted by setting the fine-tuning assembly to adjust the position of the purge needle tube 522 on the workbench 2, so that the purge needle tube 522 can effectively purge the product.

[0039] Since the purge needle 522 applies an oblique force to the product, the product always has a tendency to move obliquely downward during the process of the product moving toward the lower feed port. In order to ensure the smooth rotation of the workbench 2, a gap will inevitably be left between the workbench 2 and the collection box 51, which may cause the product to be stuck between the workbench 2 and the collection box 51 during the unloading process. Based on this, in some embodiments, the collection box 51 is provided with an extension protrusion 511 extending to the bottom of the workbench 2 on the side facing the workbench 2, and the extension protrusion 511 is connected to the feed port and the interior of the collection box 51. Through the cooperation of the extension protrusion 511 and the feed port, the collection box 51 can present an L-shaped notch at the edge of the workbench 2, so that the product can smoothly enter the collection box 51.

[0040] In some embodiments, see Appendix Figure 1 , 3 As shown, a vibrating loading tray 31 is provided on the loading station 3, and a feeding port and a discharging port are provided on the vibrating loading tray 31 respectively; a discharging guide rail 32 extending to the top of the workbench 2 is arranged at the discharging port, and a guide groove 321 for a single product to move is provided on the discharging guide rail 32. The products can be arranged and loaded by setting the vibrating loading tray 31 to ensure the consistency of product loading. Furthermore, the discharging guide rail 32 is arranged obliquely with the workbench 2. This arrangement enables the product to have an oblique initial velocity when entering the workbench 2, so as to facilitate the synchronous rotation of the product with the workbench 2.

[0041] Furthermore, a stop plate 322 that can cover the guide groove 321 is provided at one end of the discharge guide rail 32 close to the worktable 2, and the stop plate 322 extends toward the worktable 2. Since the discharge guide rail 32 is located above the worktable 2, when the product enters the worktable 2 from the guide groove 321, the product has a tendency to move downward. Therefore, the setting of the stop plate 322 can prevent the product from flipping when it enters the worktable 2 from the guide groove 321.

[0042] Furthermore, the feed port is connected to the collecting box 51 of one of the unloading areas 5. The unloading area 5 is the undetermined unloading area. Since the product in the undetermined unloading area is a product with abnormal detection, it is connected to the feed port, so that the product can flow back to the vibrating loading tray 31, and re-load and detect.

[0043] In some embodiments, a mounting frame 41 is provided on the CCD inspection station 4 , and a visual camera 42 located above the workbench 2 is installed on the mounting frame 41 .

[0044] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
