This detection equipment realizes automatic product loading, automatic barcode scanning, automatic detection, and intelligent unloading, reducing manual operation, with high detection efficiency, high detection accuracy, and no missed detection.

[0059] Next, join Figures 1-11 This application describes an automatic color measuring device provided in an embodiment, which is mainly suitable for detecting color difference after printing on mobile phone films.

[0060] The automatic detection device includes a machine base 100, a feeding device, a transfer device 30, a positioning device 40, a transfer device 50, a barcode scanning device, a detection device 70, a sorting and receiving device, and a control device (not shown in the attached drawings).

[0061] The machine 100 is equipped with multiple workstations, including a loading workstation, a barcode scanning workstation, an inspection workstation, and a unloading workstation. The machine is also equipped with a housing 110.

[0062] The transfer device 30 is installed on the machine base 100, and multiple carriers 32 are installed on the transfer device 30. The transfer device 30 is used to drive the carriers 32 to circulate sequentially between multiple workstations in a preset transfer direction.

[0063] The transplanting device 50 is set at the loading station and is used to transport the test sample to the carrier that has been transferred to the position.

[0064] The barcode scanning device is installed at the barcode scanning station and is used to scan and collect data on the items to be tested that have been transferred to the station.

[0065] The detection device 70 is set at the detection station for color difference detection of the samples to be tested after they have been transferred to the station.

[0066] The sorting and receiving device is installed at the unloading station and is used to sort and receive the test products that have been transferred to the designated location.

[0067] The positioning device 40 is set at the loading station and is located upstream of the transfer device 50. The positioning device 40 is used to limit the test sample to a set position, and the transfer device 50 is used to transfer the test sample at the set position to the carrier 32 located at the loading station.

[0068] A feeding device is installed on the machine base 100 and located upstream of the positioning device 40, and is used to feed the test sample to the positioning device 40.

[0069] The control device is electrically connected to the feeding device, the transfer device 30, the positioning device 40, the transplanting device 50, the barcode scanning device, the detection device 70, and the sorting and receiving device.

[0070] The following example uses a set of products to illustrate the testing sequence of the testing equipment in this application. The feeding device first transports the product to be tested to the positioning device 40, which pre-positions the product. The transfer device 50 then moves the pre-positioned product to the carrier 32 located at the loading station on the transfer device 30. The transfer device 30 then... Figure 2The flow (rotation) is indicated by the middle arrow A. When the flow device 30 moves the carrier containing the test item to the scanning station, the scanning device scans and collects the code of the test item. Then, when the flow device 30 moves the carrier 32 containing the test item to the detection station, the detection device 70 performs color difference detection on the test item. Finally, when the flow device 30 moves the carrier containing the test item to the unloading station, the sorting and receiving device sorts and receives the test item. It should be noted that the color measuring devices located at different stations in this application operate simultaneously, which helps to improve the detection speed.

[0071] refer to Figures 8-9 In this embodiment, the transfer device 30 includes a rotating disk 31 and a rotary drive (not shown in the accompanying drawings). The rotating disk 31 is disposed at the output end of the rotary drive, and multiple carriers 32 are distributed on the surface of the rotating disk 31. The carriers 32 are used to fix the products to be tested. The rotating disk 31 is driven to rotate by the rotary drive, thereby causing the carriers 32 on the rotating disk 31 to circulate sequentially between multiple workstations according to a preset transfer direction. In this embodiment, the transfer device 30 realizes the movement of the carriers 32 between various workstations through rotation, thereby realizing the rotary production line inspection of products. This design makes the production line more compact and helps save equipment space. Furthermore, multiple carriers 32 are evenly distributed around the circumference of the rotating disk 31, and the distribution positions of the multiple carriers 31 correspond one-to-one with the distribution positions of the multiple workstations. This design allows the carriers to correspond to the devices on each workstation. Furthermore, the carriers 32 are equipped with positioning structures, including a vacuum adsorption platform 321. By setting the adsorption platform, the test items on the carriers 32 are positioned. This design avoids the movement of the test items during the flow of the transfer device and helps improve the accuracy of the test.

[0072] In this embodiment, each carrier 32 is equipped with an identification sensor (not shown in the attached drawings). The identification sensor (not shown in the attached drawings) is used to identify whether there is a product to be tested on the carrier 32. By setting the identification sensor, the detection device 70, the barcode scanning device and the sorting and receiving device are prevented from working when the workstation is empty, which helps to improve the automation effect of the detection equipment.

[0073] refer to Figure 6In this embodiment, the transfer device 50 transports the test sample to the carrier that flows to the loading station. Specifically, the transfer device includes: a support frame 51 mounted on the machine base, an XZ axis moving module, and a second adsorption component 54. The XZ axis moving module is mounted on the support frame 51. The second adsorption component 54 is mounted on the moving end of the XZ axis moving module. The XZ axis moving module drives the second adsorption component 54 to move between the positioning device 40 and the carrier 32 located at the loading station. The second adsorption component 54 includes a second base 541 mounted on the moving end of the XZ axis moving module and a plurality of second suction cups 542 mounted on the second base 541. Specifically, the XZ axis moving module includes a first X-axis moving module 52 mounted on the support frame 51 and a first Z-axis moving module 53 mounted on the moving end of the first X-axis moving module 52, wherein the second base 541 is mounted on the moving end of the first Z-axis moving module 53.

[0074] refer to Figure 6 and Figure 7 In this embodiment, the positioning device 40 is located at the loading station and upstream of the transfer device 50. The positioning device 40 is used to confine the test sample to a set position, and the transfer device 50 is used to transfer the test sample at the set position to the carrier 32 located at the loading station. By designing the positioning device 40, on the one hand, it is beneficial for the transfer device 50 to accurately grasp the position, and on the other hand, it can improve the accuracy of placing the test sample on the carrier 32, thereby improving the accuracy of subsequent testing and improving testing efficiency.

[0075] refer to Figure 6 and Figure 7In this embodiment, the positioning device 40 includes a positioning platform 41 and a transmission mechanism. The positioning platform is equipped with multiple placement stations (not shown in the figure). Each placement station (not shown in the figure) is provided with a positioning part 42 in the circumferential direction. The positioning part 42 is used to limit the test item to a set position at the placement station. The transmission mechanism is located at the bottom of the positioning platform and connected to the positioning part 42. The transmission component is used to drive the multiple positioning parts 42 to move away from or towards the set position synchronously. Furthermore, each positioning part 42 includes at least one first positioning element 421, at least one second positioning element 422, at least one third positioning element 423, and at least one fourth positioning element 421. The first positioning element 421 and the second positioning element 422 are respectively distributed on opposite sides of the length direction of the placement station, and the third positioning element 423 and the fourth positioning element 424 are respectively distributed on opposite sides of the width direction of the placement station. The transmission mechanism includes a first transmission group 43 and a second transmission assembly 44. The first transmission assembly 43 is used to drive the first positioning element 421 and the second positioning element 422 to reciprocate along the width direction of the placement station (in the direction indicated by arrow B in the figure), and the first positioning element 421 and the second positioning element 422 move synchronously and in opposite directions. The moving component 44 is used to drive the third positioning member 423 and the fourth positioning member 424 to reciprocate along the length direction of the placement station (in the direction indicated by arrow C in the figure). The third positioning member 423 and the fourth positioning member 424 move synchronously and in opposite directions. After the positioning device 40 pre-positions the test item in the set position, the XZ axis moving module drives the multiple second suction cups 542 on the second base 541 to adsorb the test item on the placement station onto the carrier located at the loading station. Due to the pre-positioning by the positioning device 40, the multiple second suction cups can pick up the test item at the accurate position, which is beneficial for the test item on the second suction cup to be placed in the accurate position on the carrier, avoiding misplacement of the test item, thereby improving the subsequent detection accuracy and detection efficiency.

[0076] Specifically, the first transmission assembly 41 includes a first drive motor 431, a first driving gear (not shown in the figure) disposed at the output end of the first drive motor 431, and a first driven gear 432 disposed on the substrate. The first driving gear and the first driven gear 432 are connected by a first conveyor belt 433. The first conveyor belt 413 includes a first upper end 4331 near the positioning platform 41 and a first lower end 4332 away from the positioning platform 41. A first mounting member 45 is disposed on the first upper end 4331 of the first conveyor belt 433, which is connected to a first positioning member 421. A second mounting member (not shown in the figure) is disposed on the first lower end 4332 of the first conveyor belt 433, which is connected to a second positioning member 422. The second transmission assembly 44 includes a second drive motor (not shown in the figure), a second driving gear (not shown in the figure) disposed at the output end of the second drive motor, and a second driven gear 442 disposed on the substrate. The second driving gear and the second driven gear 442 are connected by a first drive motor and a second driven gear 442. The two are connected by a second conveyor belt 443. The second conveyor belt 443 includes a second upper end 4431 near the positioning platform 41 and a second lower end 4432 away from the positioning platform 41. A third mounting member (not shown in the figure) is provided on the second upper end 4431 of the second conveyor belt 443, which is connected to a third positioning member 423. A fourth mounting member (not shown in the figure) is provided on the second lower end 4432 of the second conveyor belt 443, which is connected to a fourth positioning member 424. When the first drive motor 431 rotates in the forward direction, it drives the first mounting member 421 and the second positioning member 422 to move closer to the set position at the same time. When the first drive motor 431 rotates in the reverse direction, it drives the first mounting member 421 and the second positioning member 422 to move away from the set position at the same time. When the second drive motor rotates in the forward direction, it drives the third mounting member 423 and the fourth positioning member 424 to move closer to the set position at the same time. When the second drive motor rotates in the reverse direction, it drives the third mounting member 423 and the fourth positioning member 424 to move away from the set position at the same time.

[0077] It should be noted that the positioning platform in this application has two placement stations, which requires two positioning parts. Only one first transmission component is needed, and the number of second transmission components is the same as the number of placement stations.

[0078] refer to Figures 3-5 In this embodiment, the feeding device includes a storage mechanism 10 and a loading mechanism 20. The loading mechanism 20 is used to transport the test sample in the storage mechanism 10 to the positioning device 40.

[0079] refer to Figure 3In this embodiment, the storage mechanism 10 includes a storage bin 11, a lifting mechanism 12, and a sensor assembly 13. The storage bin 11 includes a first support portion 111, on which a plurality of storage frames 112 are provided. Each storage frame 112 has a first support portion (not shown in the figure) slidably disposed therein, which is used to support the sample to be tested. A first detector 14 is disposed on the top of each storage frame 112, which is used to detect whether there is a sample to be tested at the feeding position of the first support portion. The lifting mechanism 12 is connected to the first support portion and is used to drive the first support portion to move along the axial direction of the storage frame 112. The sensor assembly 13 is disposed on the lifting mechanism 12 and is used to limit the maximum and / or minimum allowable conveying height of the first support portion. Specifically, the lifting mechanism 12 drives the first support part to move (rise or fall) along the axial direction of the storage frame 112, thereby causing the test item on the first support part to rise or fall. When the first detector 14 detects that there is no test item at the feeding position of the first support part, it drives the lifting mechanism 12 to raise the first support part, so that there is a test item at the feeding position, which facilitates the picking up by the feeding mechanism. The sensor assembly 13 includes a first sensor 131 and a second sensor 132. The first sensor 131 and the second sensor 132 are arranged side by side, and the height of the first sensor 131 is at least higher than that of the second sensor 132. The second position sensor 132 is set at a certain height. The first sensor 131 is used to limit the maximum allowable conveying height of the first support part, and the second sensor 132 is used to limit the minimum allowable conveying height of the first support part. Preferably, multiple storage boxes 112 are snapped onto the first support part 111. The multiple storage boxes 112 are an integrated structure, and the multiple storage boxes 112 are equipped with a first clamping part 16. This design is conducive to realizing the rapid replacement of multiple storage boxes 112. In this embodiment, the storage mechanism 10 can realize the automation of the supply of the test product, save labor costs, and improve production efficiency.

[0080] refer to Figures 3-4 Furthermore, the storage mechanism 10 also includes an anti-stacking mechanism 15, which is disposed on the side of the top of the storage bin 112. This mechanism is used to blow air and / or brush the sample from the side when it is adsorbed, preventing multiple samples from stacking together and being grabbed. Specifically, the anti-stacking mechanism 15 can be a blowing section 151a. During the upward movement of the sample, the blowing section 151a blows air onto the edge of the sample, eliminating static electricity and preventing the first suction cup from adsorbing two or more products. Alternatively, the anti-stacking mechanism can be a brush 151b. During the upward movement of the sample, the edge of the sample contacts the bristles of the brush 151b, eliminating static electricity. The downward force of the brush against the sample is much less than the suction force of the gripping robot's suction cup on the surface of the battery electrode, allowing unseparated stacked samples to be brushed off, thus preventing stacking.

[0081] refer to Figure 5 In this embodiment, the feeding mechanism 20 includes a first robot 21 and a first adsorption component 22. The first robot 21 drives the first adsorption component 22 to move between the storage mechanism 10 and the positioning device 40. The first adsorption component 22 includes a first base 221 connected to the arm end of the first robot 21, and a plurality of first suction cups 222 disposed on the first base 221. Preferably, a rapid dispensing device 223 is also disposed on the first base 221. By setting the rapid dispensing device, the electrostatic adsorption phenomenon of the first suction cups is avoided when picking up materials. The adsorbed test items are stacked and dispensed. Specifically, the rapid dispensing device mainly uses a high-frequency solenoid valve and a floating cylinder to perform high-frequency vibration. The high-frequency vibration generates vibration to achieve the purpose of stacking and layering materials. In this embodiment, the feeding mechanism can realize the automation of feeding test items, save labor costs, and improve production efficiency.

[0082] refer to Figure 9 In this embodiment, the scanning device includes a barcode scanner 61 and an XY moving component 62. The moving end of the XY moving component 62 is provided with a fine-tuning fixing member 63. The barcode scanner 61 is mounted on the fine-tuning fixing member and is used to acquire the QR code image on the item to be tested. The XY moving component 62 drives the barcode scanner 61 located on the fine-tuning fixing member to move along the XY directions. In this embodiment, the fine-tuning fixing member can not only mount the barcode scanner on the XY moving component 62, but also adjust the mounting angle of the barcode scanner 61, so that the barcode scanner can accurately and clearly acquire the QR code image on the item to be tested.

[0083] refer to Figure 10 In this embodiment, the detection device 70 includes an XYZ axis moving module and a color difference tester group 74. The XYZ axis moving module is mounted on the machine base 100, and the color difference tester group is mounted on the moving end of the XYZ axis moving module. The color difference tester group includes a third base 741 on which the moving end of the XYZ axis moving module is mounted, and multiple color difference testers 742 mounted on the third base 741. The third base 741 is also equipped with a pressure sensor 75. When the transfer device 50 transfers the sample to be tested to the detection station, the XYZ axis moving module drives the multiple color difference testers on the third base 741. The 742 moves in multiple directions to perform color difference detection on multiple test items on the carrier. Here, the number of test items is the same as the number of color difference testers 742. This design facilitates rapid detection of the test items on the carrier. Specifically, the XYZ axis moving module in this embodiment includes a second Y-axis moving module 71 set on the machine base, a second X-axis moving module 72 set on the moving end of the second Y-axis moving module 71, a second Z-axis moving module 73 set on the moving end of the second X-axis moving module 72, and a third base 741 set on the moving end of the second Z-axis moving module 73.

[0084] refer to Figure 1 and Figure 11 In this embodiment, the sorting and receiving device includes a first receiving bin 81, a second receiving bin 82, and a discharging mechanism 90. When the product to be tested transferred to the discharging station is a qualified product, the discharging mechanism 83 is used to transport the qualified product to the first receiving bin 81. When the product to be tested transferred to the discharging station is a defective product, the discharging mechanism 83 is used to transport the defective product to the second receiving bin 82. Specifically, the discharging mechanism 83 includes a second robot (not shown in the figures) and a third adsorption component (not shown in the figures). The second robot drives the third adsorption component to interact with the first receiving bin 81 and / or the second receiving bin 82 at the discharging station of the transfer device. The two receiving bins 82 move between each other; the third adsorption component includes a third base set at the end of the second robot, and multiple third suction cups are configured on the third base. The first receiving bin and the second receiving bin have the same structure. Here, the first receiving bin is used as an example. The first receiving bin includes a second support part 811 and multiple storage frames 812 set on the support part. Each storage frame 812 is provided with a support part for supporting the product (not shown in the figure). Here, the storage frame 512 is snapped into the second support part 811. The storage frame is also provided with a second clamping part 813. The design of the second clamping part can facilitate the quick replacement of the storage frame. The control device detects the structure based on the color difference detector 741. If the test product is determined to be qualified, the control device drives the second robot to drive the third adsorption component to pick up the qualified product from the carrier located at the unloading station, and then transports the qualified product to the first receiving bin 81. If the test product is determined to be qualified, the control device drives the second robot to drive the third adsorption component to pick up the unqualified product from the carrier located at the unloading station, and then transports the unqualified product to the second receiving bin 82.
