Description

Technical Field

[0001] The invention relates to the technical field of precision detection, in particular to a material loading and unloading detection device. Background Art

[0002] In the existing mobile phone screen lamination and assembly production line, traditional inspection machines mostly use a single upstream loading method to directly throw the materials downstream. This fixed working mode requires customized design according to the characteristics of the upstream equipment, resulting in a large design workload, a long R&D cycle, and difficulty in adapting to changing production needs. At the same time, defective products produced during the mobile phone screen lamination and assembly process usually need to be checked through manual sampling, which is not only labor-intensive and inefficient, but also prone to missed inspections due to human factors.

[0003] In addition, when the upstream feeding equipment fails, the existing inspection machine is often unable to continue the inspection work, thus affecting the overall operation efficiency of the production line.

[0068] The first input and output line component 101 includes an input and output conveyor line 1011 for transferring carriers, a lifting module 1012 is provided at the output end of the input and output conveyor line 1011, and a supporting tooth fork 1013 for supporting the carrier transported on the input and output conveyor line 1011 is provided at the lifting end of the lifting module 1012; a positioning and shooting component 13 is provided above the carrier input and output line component 10, and the positioning and shooting component 13 includes a fixing frame 131, and a positioning camera 132 is fixedly installed at the end of the fixing frame 131.

[0069] See also Figures 1 to 3 as well as Fig.12 , Fig.13As shown, the first in-and-out line assembly 101 and the second in-and-out line assembly 102 have the same structure and the same working principle. Here, it can be set that the first in-and-out line assembly 101 is used to load the carrier containing products, and the second in-and-out line assembly 102 is used to unload the carrier containing qualified products; the first in-and-out line assembly 101 loads the stacked products that have not been inspected. Specifically, the in-and-out conveyor line 1011 conveys the stacked products that have not been inspected to the lifting position of the lifting module 1012. At this time, the load-bearing fork 1013 is located below the carrier, and then the lifting module 1012 drives the carrier to rise to a predetermined position through the load-bearing fork 1013, and waits until the uninspected products in the top carrier are transported away. Finally, the empty tray is transported to the lifting position on the second input and output line assembly 102 through the tray clamping and transporting assembly 11. During the inspection process, the lifting module 1012 drives the trays loaded with uninspected products to rise in turn, and then the products in the top tray are transported and inspected. The tray clamping and transporting assembly 11 transports the empty tray with the top product transported out to the position of the second input and output line assembly 102, and the second input and output line assembly 102 drives the empty trays to descend in turn. When the empty trays on the second input and output line assembly 102 are stacked to a certain height, they are transported out. Similarly, when the tray loaded with products in the first input and output line assembly 101 is used up, a new tray loaded with uninspected products can be re-loaded through the input and output conveying line 1011.

[0070] In this embodiment, the positioning camera 132 is used to confirm and locate the transport position of the carrier plate clamping and transporting assembly 11, so that it can accurately transport the corresponding carrier plate.

[0071] The carrier clamping and transporting assembly 11 transports the carrier on the first input and output line assembly 101 to the second input and output line assembly 102 or transports the carrier on the second input and output line assembly 102 to the first input and output line assembly 101. The transporting end of the carrier clamping and transporting assembly 11 is located above the carrier input and output line assembly 10. The carrier clamping and transporting assembly 11 includes a fourth gantry 111 fixedly mounted on the machine 1, a transport linear module 112 is fixedly mounted on the fourth gantry 111, a moving frame 113 is fixedly mounted on the moving end of the transport linear module 112, a fixed plate 114 is fixedly mounted on the bottom surface of the moving frame 113, and clamping structures 115 that move toward or away from each other are fixedly mounted on both ends of the fixed plate 114.

[0072] See also Figures 1 to 3 ,as well as Fig.14As shown, the clamping structures 115 at both ends of the bottom of the fixed plate 114 are driven to move by the transport linear module 112, so that the carrier plate clamped by the two clamping structures 115 is transported. Specifically, the empty carrier plate is lifted and moved between the two clamping structures 115 through the first input and output line assembly 101. The two clamping structures 115 are moved close to each other to clamp the empty carrier plate therebetween, and then the transport linear module 112 is cooperated to realize the transport of the carrier plate.

[0073] The clamping structure 115 includes a connecting plate 1151 fixedly mounted on the fixing plate 114, a clamping cylinder 1152 fixedly mounted on the bottom surface of the connecting plate 1151, a clamping block 1153 slidably connected to the bottom surface of the connecting plate 1151 via a guide rail slider assembly, a driving end of the clamping cylinder 1152 is connected to the clamping block 1153; a material beating lifting cylinder 1155 is also fixedly mounted on the outer end surface of the clamping block 1153, a carrier plate 1156 is fixedly mounted on the lifting end of the material beating lifting cylinder 1155.

[0074] The inner side surface of the clamping end of the clamping block 1153 is provided with a receiving groove 1154 adapted to the lifting bosses at both ends of the carrier, and the inner end surface of the receiving groove 1154 is provided with a guide hole 1159. The end surface of the fixed plate 114 is also fixedly mounted with a connecting frame 1157, and the inner side surface of the bottom of the connecting frame 1157 is provided with a guide shaft 1158 adapted to the guide hole 1159.

[0075] See also Fig.15 , Fig.16 and Fig.18 As shown, when clamping is required, first start the clamping cylinders 1152 on both sides to drive the clamping block 1153 to move, so that the lifting bosses on both sides of the carrier plate (not marked in the figure) are located in the receiving groove 1154. During the movement of the clamping block 1153, a supporting force in the height direction of the clamping block 1153 can be given through the cooperation of the guide hole 1159 and the guide shaft 1158. That is to say, during the movement of the clamping block 1153, the guide shaft 1158 is always located in the guide hole 1159, so that the clamping block 1153 can bear a heavier weight. After the lifting protrusion of the carrier plate is located in the receiving groove 1154, the material lifting cylinder 1155 drives the carrier plate 1156 to move downward to prevent the clamped material tray from driving the next material tray to lift, thereby separating the two adjacent material trays.

[0076] The working process of the present invention is as follows: Figures 1 to 3 as well as Fig.12 As shown, the present application can also implement corresponding detection when the corresponding upstream equipment fails and shuts down. Compared with the existing manual and equipment, the equipment in the present application is more practical and more efficient.

[0077] Specifically, when the upstream and downstream products are able to work normally, the loading and correction transfer module 2 carries the products from the upstream, and the loading and correction transfer module 2 moves the products to the upper detection module 3 to detect the upper surface of the products. After the detection is completed, the loading and correction transfer module 2 moves the detected products to the loading position of the transfer component 4, and the transfer component 4 moves the products on the loading and correction transfer module 2 after the upper surface detection. If the upper surface detection of the product is qualified, the transfer component 4 moves the product to the lower detection module 5 to detect the lower surface of the product; if the upper surface detection is unqualified, the transfer component 4 moves the product to the NG product unloading belt line 9 position, and unloads the unqualified products through the NG product unloading belt line 9 position, or transfers the product to the NG product unloading belt line 9 position for unloading after detection by the lower detection module 5;

[0078] If the lower surface of the product is unqualified when detected at the lower detection module 5 and qualified at the upper detection module 3, the product is transported to the NG product unloading belt line 9 to unload the unqualified product;

[0079] If the lower surface of the product is found to be qualified when detected at the lower detection module 5 (and is also found to be qualified when detected at the upper detection module 3), the product will be transported to the intermediate transfer assembly 6 (at this time, the intermediate transfer assembly 6 is waiting at the position of the transport and transfer assembly 4), and the intermediate transfer assembly 6 will transport the products that have passed the upper and lower surface inspections to the position of the unloading transfer assembly 7, and then the unloading transfer assembly 7 will transport the qualified products on the intermediate transfer assembly 6 to the OK product unloading belt line 8 for unloading of qualified products, thereby completing the inspection of the products.

[0080] Specifically, when the upstream equipment fails and shuts down, the first in-and-out line assembly 101 of the tray in-and-out line assembly 10 will transfer the tray loaded with stacks of products to the loading position of the transport and transfer assembly 4, and then the transport and transfer assembly 4 will transfer the products from the tray to the lower detection module 5 to first detect the lower surface. Correspondingly, the upper surface can also be detected first. In practice, the upper or lower surface can be detected as needed. Here, the lower surface detection is taken as an example; after the products in the top tray of the first in-and-out line assembly 101 are transported by the transport and transfer assembly 4, the empty tray is then transported to the second in-and-out line assembly 11 by the tray clamping and transporting assembly Component 102 is at the position; at this time, the latest carrier plate containing uninspected products at the top of the first in-and-out line component 101 is lifted to the predetermined loading position to prepare for the next handling and inspection; next, the products are inspected by the lower inspection module 5 and the upper inspection module 3 respectively. If one of the lower inspection module 5 and the upper inspection module 3 fails the inspection, the handling and transfer component 4 will transport the unqualified products to the NG product unloading belt line 9 for unloading; or if the products are inspected at both the upper inspection module 3 and the lower inspection module 5 and fail the inspection at one of the two positions, the handling and transfer component 4 will transport the unqualified products to the NG product unloading belt line 9 for unloading;

[0081] When both the upper and lower surfaces of the product are inspected and qualified, the product is transported to the position of the intermediate transfer assembly 6. Through the linkage of the intermediate transfer assembly 6 and the unloading transfer assembly 7, the qualified product is transported to the OK product unloading belt line 8 to unload and feed the downstream equipment, thereby completing the inspection of qualified products.

[0082] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
