[0014] The present invention also provides a detection method based on the detection device described in any one of the preceding claims, comprising: The first rotating seat drives all workpiece fixing seats to rotate around the center of the first rotating seat, and the feeding mechanism sequentially transports the workpieces to be inspected to the adjacent workpiece fixing seats. The workpiece to be inspected rotates synchronously with the workpiece holder and enters the inspection area of ​​the first inspection piece in sequence. The first inspection piece inspects the workpiece, and during the inspection process, the corresponding workpiece holder rotates around its own axis to achieve inspection of the workpiece at different angles. The second rotating seat drives all the first workpiece adsorption components to rotate around the center of the second rotating seat. The first workpiece adsorption components sequentially adsorb and transfer the workpieces that have been detected by the first detection component on the adjacent workpiece fixing seats to the second detection component, causing the workpieces to rotate synchronously and enter the detection area of ​​the second detection component in sequence, where they are detected by the second detection component.

[0015] The beneficial effects of this invention are: (1) The present invention automatically transports empty material trays to a predetermined position through the material tray feeding component, and then transports the empty material trays to the first unloading component and the second unloading component through the material tray handling component. This not only realizes the automatic feeding of empty material trays with a high degree of automation, but also classifies qualified and unqualified workpieces for unloading, which facilitates the subsequent inspection process and effectively improves the inspection efficiency.

[0016] (2) The present invention drives several workpieces to rotate synchronously by rotating the seat, and the several workpieces are evenly arranged on the same circumference, so that the several workpieces can enter the detection area of ​​the detection piece in sequence, thereby realizing the orderly and efficient detection of the battery.

[0017] (3) In this invention, the workpiece fixing seat is rotatably mounted on the first rotating seat. When the first detection component detects the workpiece, the corresponding workpiece fixing seat rotates around its own axis under the drive of the rotation drive component, thereby driving the workpiece on it to rotate synchronously, which facilitates the first detection component to detect the workpiece from multiple angles.

[0018] (4) In this invention, the edges of the first rotating seat and the second rotating seat are tangent, so that during the rotation of the first rotating seat and the second rotating seat, the first workpiece adsorption member can be aligned with the workpiece fixing seat in the vertical direction. At this time, by driving the first workpiece adsorption member to descend, the workpiece on the workpiece fixing seat can be adsorbed and transferred to the first workpiece adsorption member, thereby transferring the workpiece after the first detection component has been detected to the second detection component.

[0021] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] See Figures 1-5 This application provides a testing device, which includes a worktable, a testing mechanism 100 disposed on the worktable, a loading mechanism 200, and a unloading mechanism 300. The loading mechanism 200 automatically transports the workpiece to be tested to the testing mechanism 100, where the testing mechanism 100 tests the workpiece. After testing, the unloading mechanism 300 automatically unloads the workpiece, and during unloading, it can automatically classify the workpiece based on the testing results.

[0023] Specifically, the loading mechanism 200 includes a loading conveyor belt 210 and a loading robot 220 fixedly mounted on the worktable. The loading robot 220 is located on one side of the loading conveyor belt 210. The workpiece to be inspected is conveyed onto the loading conveyor belt 210 by an external conveying assembly and then conveyed to a preset position by the loading conveyor belt 210. The loading robot 220 grabs the workpiece to be inspected from the loading conveyor belt 210 and transfers it to the inspection mechanism 100.

[0024] Preferably, the feeding mechanism 200 further includes a re-inspection workpiece conveyor belt 230 for conveying re-inspection workpieces. Workpieces requiring re-inspection are conveyed by the re-inspection workpiece conveyor belt 230. This re-inspection workpiece conveyor belt 230 is fixedly mounted on the workbench and located on the side of the feeding conveyor belt 210 away from the feeding robot 220. The conveying direction of the re-inspection workpiece conveyor belt 230 is perpendicular to the conveying direction of the feeding conveyor belt 210, and one end of the re-inspection workpiece conveyor belt 230 in the conveying direction is adjacent to the side of the feeding conveyor belt 210. A third crossbeam 240 is fixedly mounted above the re-inspection workpiece conveyor belt 230, the length of which is parallel to the conveying direction of the re-inspection workpiece conveyor belt 230. A slide rail extending along the length of the third crossbeam 240 is provided on the third crossbeam 240, and a third movable seat 250 is slidably mounted on this slide rail. A lifting drive component is fixedly installed on the third movable seat 250, and this lifting drive component is drivenly connected to the second lifting seat 260 to drive the second lifting seat 260 to move vertically. A third workpiece adsorption component 270 for adsorbing workpieces is fixedly installed on the second lifting seat 260.

[0025] It should be noted that the feeding conveyor belt 210 is located directly below the moving path of the third workpiece adsorption component 270. That is, when the third moving seat 250 slides along the slide rail to a certain position, the third workpiece adsorption component 270 is located directly above the feeding conveyor belt 210. At this time, the third workpiece adsorption component 270 can place the workpiece adsorbed on it onto the feeding conveyor belt 210, and then be transported to the detection mechanism 100 by the feeding robot 220.

[0026] The inspection mechanism 100 is used to inspect workpieces to be inspected. The inspection mechanism 100 includes a first inspection component 110 and a second inspection component 120. The first inspection component 110 includes a first rotating seat 111 rotatably mounted on a worktable. The first rotating seat 111 is driven by a rotary drive component fixed within the worktable and rotates around its own axis. The first rotating seat 111 is approximately circular. A plurality of workpiece fixing seats 112 are evenly distributed on the same circumference on the first rotating seat 111. A plurality of first inspection components are fixedly disposed in the center of the first rotating seat, also evenly distributed on the same circumference. The number of first inspection components is the same as the number of workpiece fixing seats 112, and each workpiece fixing seat 112 is located within the inspection area of ​​an adjacent first inspection component.

[0027] Preferably, each workpiece holder 112 is rotatably mounted on the first rotating seat 111 around its own axis. That is, each workpiece holder 112 has a rotary drive component located below it, which is fixedly mounted on the first rotating seat 111. The workpiece holder 112 is drivenly connected to the corresponding rotary drive component. When the first detection component detects any workpiece, the corresponding workpiece holder 112 rotates around its own axis under the drive of the rotary drive component, thereby causing the workpiece on it to rotate synchronously, facilitating multi-angle detection of the workpiece by the first detection component.

[0028] The second detection assembly 120 includes a second rotating seat 121 rotatably mounted on a worktable. The second rotating seat 121 is driven by a rotating drive component fixed within the worktable and rotates around its own axis. The second rotating seat 121 is also approximately circular, and its diameter is smaller than that of the first rotating seat 111. Several lifting drive devices are fixedly mounted on the second rotating seat 121, and each lifting drive device is drivenly connected to a first workpiece adsorption component 123, which can drive the first workpiece adsorption component 123 to move vertically. The several first workpiece adsorption components 123 are evenly distributed on the same circumference. Several second detection components are fixedly mounted in the middle of the second rotating seat. These second detection components are also evenly distributed on the same circumference, and each first workpiece adsorption component 123 is located within the detection area of ​​an adjacent second detection component.

[0029] It should be noted that the distance between the center of the first rotating seat 111 and the center of the second rotating seat 121 is equal to the sum of the distance between the center of the workpiece fixing seat 112 and the center of the first rotating seat 111, and the distance between the center of the first workpiece adsorption member 123 and the center of the second rotating seat 121. Thus, during the rotation of the first rotating seat 111 and the second rotating seat 121, when they rotate to certain angles, one of the first workpiece adsorption members 123 aligns vertically with one of the workpiece fixing seats 112. At this point, by driving the first workpiece adsorption member 123 to descend, the workpiece on the workpiece fixing seat 112 can be adsorbed and transferred to the first workpiece adsorption member 123, thereby transferring the workpiece that has been detected by the first detection component 110 to the second detection component 120.

[0030] Preferably, a barcode scanner 140 is also fixedly installed on one side of the worktable located on the second rotating seat 121. The distance between the barcode scanner 140 and the axis of the second rotating seat 121 is equal to the distance between the first workpiece adsorption member 123 and the axis of the second rotating seat 121, that is, the barcode scanner 140 is located directly below the moving path of each first workpiece adsorption member 123. During the rotation of the first adsorption member driven by the second rotating seat 121, each workpiece adsorbed below the first workpiece adsorption member 123 will sequentially enter the scanning area of ​​the barcode scanner 140. The barcode scanner 140 can scan each workpiece entering the scanning area to obtain the product information of the workpiece.

[0031] Furthermore, the inspection mechanism 100 also includes a third inspection component 130. This third inspection component 130 includes a CCD inspection component and a transfer conveyor component. The transfer conveyor component is used to transfer workpieces that have completed inspection by the second inspection component 120 to the CCD inspection component for further inspection. Specifically, the CCD inspection component includes a CCD inspection camera 131 fixedly mounted on the worktable and an inspection platform 132 located directly below the CCD inspection camera 131. Two workpiece placement seats 133 are fixedly mounted on the inspection platform 132. The CCD inspection camera 131 is located on one side of the second rotating seat 121. The transfer conveyor component includes a transfer conveyor belt 134 fixedly mounted on the worktable, located between the CCD inspection camera 131 and the second rotating seat 121. A second crossbeam 135 is fixedly mounted on one side of the transfer conveyor belt 134, the length direction of which is perpendicular to the conveying direction of the transfer conveyor belt 134. A slide rail extending along the length of the second crossbeam 135 is fixedly mounted on the second crossbeam 135, and a second movable seat 136 is slidably mounted on the slide rail. A second lifting drive device 137 is fixedly mounted on the second movable seat 136, and the second lifting drive device 137 is drivenly connected to the first lifting seat 138 to drive the first lifting seat 138 to rise and fall vertically. A second workpiece adsorption component 139 is fixedly mounted on the first lifting seat 138.

[0032] It should be noted that the workpiece placement seat 133 and the transfer conveyor belt 134 on the inspection platform 132 are both located directly below the moving path of the second workpiece adsorption member 139. The second workpiece adsorption member 139 can move with the second moving seat 136 to directly above the transfer conveyor belt 134. The second lifting drive device 137 drives the second workpiece adsorption member 139 downward, so that the workpiece on the transfer conveyor belt 134 can be adsorbed onto the second workpiece adsorption member 139. Then, the second moving seat 136 drives the second workpiece adsorption member 139 to directly above the workpiece placement seat 133, so that the workpiece can be placed on the workpiece placement seat 133 for inspection by the CCD inspection camera 131.

[0033] The unloading mechanism 300 includes a tray loading assembly 310, a first unloading assembly 320, a second unloading assembly 330, a tray transport assembly 340, and an unloading robot 350, all mounted on a worktable. The tray loading assembly 310, the first unloading assembly 320, and the second unloading assembly 330 are all located on the side of the CCD inspection camera 131 furthest from the first rotary base 111. The tray loading assembly 310 serves as an empty tray loading station, the first unloading assembly 320 serves as a qualified workpiece unloading station, and the second unloading assembly 330 serves as an unloading station for unqualified workpieces.

[0034] The material tray loading assembly 310 includes a first material rack 311, a first lifting platform 312 located within the first material rack 311, and a first belt conveyor fixedly installed within the first material rack 311. The first lifting platform 312 is used to hold empty material trays. A third lifting drive device for driving the first lifting platform 312 to rise and fall is fixedly installed within the first material rack 311. Two first belt conveyors are provided, respectively located on both sides of the first lifting platform 312. The conveying surfaces of the two first belt conveyors are located in the same horizontal plane. When the first lifting platform 312 is lowered to its lowest position, the upper surface of the first lifting platform 312 is lower than the conveying surface of the first belt conveyor; when the first lifting platform 312 is raised to its highest position, the upper surface of the first lifting platform 312 is higher than the conveying surface of the first belt conveyor. Two first belt conveyors transport the empty material trays from outside the first material rack 311 to the first lifting platform 312. When the empty material trays are directly above the first lifting platform 312, the first belt conveyors stop running. At this time, the first lifting platform 312 is raised by the third lifting drive device, which can lift the empty material trays to the predetermined height.

[0035] The structures of the first unloading assembly 320 and the second unloading assembly 330 are identical to those of the tray loading assembly 310. The first unloading assembly 320 includes a second material rack 321, a second lifting platform 322 located within the second material rack 321, and two second belt conveyors fixedly installed within the second material rack 321. The second lifting platform 322 is driven by a fourth lifting drive device fixedly installed within the second material rack 321. The second unloading assembly 330 includes a third material rack 331, a third lifting platform 332 located within the third material rack 331, and two third belt conveyors fixedly installed within the third material rack 331. The third lifting platform 332 is driven by a fifth lifting drive device fixedly installed within the third material rack 331.

[0036] The tray handling assembly 340 includes a first crossbeam 341 mounted above the first tray 311, the second tray 321, and the third tray 331. The length of the first crossbeam 341 is parallel to the conveying direction of the transfer conveyor belt 134. A slide rail extending along the length of the first crossbeam 341 is fixedly mounted on the first crossbeam 341, and a first movable seat 342 is slidably mounted on the slide rail. A sixth lifting drive device is fixedly mounted on the first movable seat 342, and the sixth lifting drive device is drivenly connected to the first lifting platform 312. A tray suction member 344 is fixedly mounted on the fourth lifting platform 343.

[0037] It should be noted that the first material rack 311, the second material rack 321, and the third material rack 331 are arranged sequentially along the length of the crossbeam, and the first lifting platform 312, the second lifting platform 322, and the third lifting platform 332 are all located directly below the moving path of the material tray adsorption component 344. When the first moving seat 342 moves along the length of the first crossbeam 341, the material tray adsorption component 344 can adsorb the empty material tray on the first lifting platform 312 and transfer it to the second lifting platform 322 and the third lifting platform 332.

[0038] The unloading robot 350 is used to transport qualified workpieces to the tray on the second lifting platform 322, and to transport unqualified workpieces to the tray on the third lifting platform 332.

[0039] In addition, this application embodiment also provides a detection method based on the above-described detection device. The method specifically includes the following steps: Step S101: The first rotating seat drives all workpiece fixing seats to rotate around the center of the first rotating seat, and the feeding mechanism sequentially transports the workpieces to be inspected to the adjacent workpiece fixing seats; Step S102: The workpiece to be tested rotates synchronously with the workpiece fixing seat and enters the detection area of ​​the first detection piece in sequence. The first detection piece detects the workpiece, and during the detection process, the corresponding workpiece fixing seat rotates around its own axis to detect the workpiece at different angles. Step S103: The second rotating seat drives all the first workpiece adsorption components to rotate around the center of the second rotating seat. The first workpiece adsorption components sequentially adsorb and transfer the workpieces that have been detected by the first detection component on the adjacent workpiece fixing seats to the second detection component, causing the workpieces to rotate synchronously and enter the detection area of ​​the second detection component in sequence. The second detection component detects them. At the same time, the barcode scanner sequentially obtains the workpiece information of each workpiece. Step S104: The transfer and conveying component sequentially transports the workpieces that have completed the second detection component detection on the adjacent first workpiece adsorption component to the workpiece placement seat on the detection platform, and a CCD detection camera performs CCD detection on the workpieces. Step S105: The material tray conveying assembly transports the empty material trays in the material tray loading assembly to the first unloading assembly and the second unloading assembly respectively. At the same time, the unloading robot places the workpieces that have completed CCD detection into the corresponding unloading assembly according to the detection results, thereby realizing unloading.

[0040] Therefore, the technical solution of this application automatically transports empty material trays to a predetermined position through the material tray feeding component, and then transports the empty material trays to the first unloading component and the second unloading component through the material tray handling component. This not only realizes the automatic feeding of empty material trays with a high degree of automation, but also classifies qualified and unqualified workpieces for unloading, which facilitates the subsequent inspection process and effectively improves the inspection efficiency.

[0041] In addition to the above embodiments, the present invention may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
