The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Figure 1 to Figure 5 The structure of a shoe upper last quality inspection device according to one embodiment of the utility model is schematically shown.

[0027] like Figure 1 to Figure 5 As shown, a device for detecting the quality of shoe uppers entering lasts comprises a frame 1; a transmission device 2, a three-axis driving device I3, a data acquisition device 4, a three-axis driving device II5 and a marking device 6 installed on the frame 1, wherein the transmission device can drive the shoe upper to move, the three-axis driving device I3 can drive the data acquisition device 4 to move in three-dimensional space, and the three-axis driving device II5 can drive the marking device 6 to move in three-dimensional space.

[0028] In this embodiment, the data acquisition device 4 can collect data, that is, the scanning data obtained by scanning the upper. For the specific process, reference may be made to the contents of the specific implementation method of "a method for detecting the quality of uppers entering lasts" applied by the present applicant on the same day. Since the present application protects the structural part of the device, the working method and process of the data acquisition device 4 are not required to be protected, and therefore, they will not be described in detail. At the same time, the marking device 6 marks the position on the upper to be tested corresponding to the unqualified position information by marking the position. For the specific process, reference may be made to the contents of the specific implementation method of "a method for detecting the quality of uppers entering lasts" applied by the present applicant on the same day. Since the present application protects the structural part of the device, the working method and process of the data acquisition device 4 are not required to be protected, and therefore, they will not be described in detail.

[0029] In this embodiment, if Figure 1 and Figure 2As shown, the transmission device 2 includes a transmission motor, two transmission wheels 21 and a transmission chain 22. In order to more clearly display the structure of the transmission device 2, the present application hides part of the transmission chain 22 and the transmission motor. The two ends of the transmission chain 22 are respectively sleeved on the two transmission wheels 21, that is, the left end of the transmission chain 22 is sleeved on the left transmission wheel 21, and the right end of the transmission chain 22 is sleeved on the right transmission wheel 21. The transmission motor is connected to the right transmission wheel 21. The transmission motor drives the transmission chain 22 to move through the transmission wheel 21, and the transmission chain 22 drives the shoe upper to move.

[0030] In this embodiment, a fixing plate 221 is provided on the transmission chain 22, and the shoe upper after being put into the last can be arranged on the fixing plate 221. Therefore, when the transmission motor is started, the transmission motor can drive the right transmission wheel 21 to rotate, and the transmission wheel 21 drives the transmission chain 22 to move back and forth (of course, the left transmission wheel 21 will also be driven by the transmission chain 22 to rotate), and the transmission chain 22 drives the fixing plate 221 thereon and the shoe upper arranged on the fixing plate 221 to move, so that the shoe upper moves to the data acquisition device 4 and the marking device 6 in sequence. Of course, in other embodiments, the structure of the fixing plate 221 can be adjusted accordingly according to the structure of the shoe upper.

[0031] In this embodiment, if Figure 3 to Figure 5 As shown, the three-axis driving device I3 includes an X-axis moving mechanism 31, a Y-axis moving mechanism 32 and a Z-axis moving mechanism 33. The Z-axis moving mechanism 33 is connected to the X-axis moving mechanism 31, and the X-axis moving mechanism 31 is connected to the Y-axis moving mechanism 32. The data acquisition device 4 is installed on the Z-axis moving mechanism 33. The data acquisition device 4 can be driven to move in three-dimensional space through the X-axis moving mechanism 31, the Y-axis moving mechanism 32 and the Z-axis moving mechanism 33.

[0032] Combine the following Figure 3 to Figure 5 The structure of the X-axis moving mechanism 31 is further described in detail: In this embodiment, Figure 4It can be seen that the X-axis moving mechanism 31 includes an X-axis motor 311, an X-axis support frame 312 and an X-axis moving frame 313. The X-axis motor 311 can be installed on the X-axis moving frame 313. The X-axis support frame 312 is provided with a rack, which is distributed along the X-axis direction. The rack in this embodiment is located above the X-axis moving frame 313. In other embodiments, the rack can also be set below or in the middle of the X-axis moving frame 313 according to actual needs. The output shaft of the X-axis motor 311 is coaxially connected with a gear, and the gear can cooperate with the rack. When the X-axis motor 311 is started, the X-axis motor 311 can drive the gear to rotate. Since the gear is meshed with the rack, the gear will drive the X-axis moving frame 313 to move in the X-axis direction along the X-axis support frame 312. The Z-axis moving mechanism 33 is connected to the X-axis moving frame 313, so the Z-axis moving mechanism 33 will also move with the X-axis moving frame 313.

[0033] Combine the following Figure 3 to Figure 5 The structure of the Y-axis moving mechanism 32 is further described in detail: In this embodiment, Figure 4 As can be seen in FIG. 1 , the Y-axis moving mechanism 32 includes a Y-axis motor 321, a Y-axis transmission wheel group 322, a Y-axis belt 323 and two Y-axis fixing frames 324. The Y-axis motor 321 is arranged on one of the Y-axis fixing frames 324. The Y-axis motor 321 is connected to the Y-axis belt 323 through the Y-axis transmission wheel group 322. Specifically, the structure of the Y-axis transmission wheel group 322 can be as follows: Figure 4 As shown, it includes two coaxially connected first transmission wheels and a second transmission wheel. The Y-axis motor 321 drives the two coaxially connected first transmission wheels to move through a belt, and the coaxially connected first transmission wheels drive the second transmission wheel to rotate through the Y-axis belt 323. The left end of the X-axis support frame 312 is integrally formed with a fixing buckle, and the left end of the X-axis support frame 312 is connected to the Y-axis belt 323 through the fixing buckle, and the right end of the X-axis support frame 312 is connected to the Y-axis fixed frame 324 on the right. When the Y-axis motor 321 is started, the Y-axis motor 321 can drive the Y-axis belt 323 to move through the Y-axis transmission wheel group 322, and the Y-axis belt 323 can drive the X-axis support frame 312 to move through the fixing buckle. Therefore, the X-axis support frame 312 can move along the Y-axis fixed frame 324. At the same time, since the Z-axis moving mechanism 33 is connected to the X-axis moving frame 313, the Z-axis moving mechanism 33 will also move with the X-axis moving frame 313.

[0034] Combine the following Figure 3 to Figure 5The structure of the Y-axis moving mechanism 32 is further described in detail: In this embodiment, the Z-axis moving mechanism 33 includes a Z-axis forward motor 331, a Z-axis reverse motor 332, a screw 333, two screw nuts 334 and a Z-axis belt 335. The Z-axis forward motor 331 is connected to the upper screw nut 334 through the Z-axis belt 335, and the Z-axis reverse motor 332 is connected to the lower screw nut (not shown in the figure) through the Z-axis belt 335. The screw 333 cooperates with the two screw nuts 334, and the data acquisition device 4 is installed at the lower end of the screw 333. When the Z-axis is to rise, the Z-axis forward motor 331 is started, and the Z-axis forward motor 331 drives the screw nut 334 to rotate. Since the screw 333 is a screw, the screw 333 will rise. Conversely, when the Z-axis reverse motor is started, the Z-axis falls.

[0035] Therefore, through the above, the X-axis moving mechanism 31, the Y-axis moving mechanism 32 and the Z-axis moving mechanism 33 can drive the data acquisition device 4 to move in three-dimensional space.

[0036] In this embodiment, if Figure 5 As shown, it also includes an angle rotation device 7, which can be installed at the lower end of the screw rod 333. The angle rotation device 7 can drive the data acquisition device 4 to rotate around the Y-axis direction.

[0037] In this embodiment, if Figure 5 As shown, the angle rotation device 7 includes an angle rotation motor 71, an angle rotation belt 72, an angle transmission wheel 73 and an angle rotation fixed frame 74. The angle rotation fixed frame 74 is arranged at the lower end of the screw rod 333, and the angle rotation motor 71 is arranged on the angle rotation fixed frame 74. When the angle rotation motor 71 is started, the angle rotation motor 71 can rotate through the angle transmission wheel 73, and the angle transmission wheel 73 drives the data acquisition device 4 to rotate around the Y-axis direction (which can also be understood as the Y-axis) through the angle rotation belt 72.

[0038] In this embodiment, the structure of the three-axis driving device II is exactly the same as that of the three-axis driving device I3, so the structure of the three-axis driving device II is not described in detail.

[0039] In the utility model, the shoe upper can be placed on the transmission device 2, and the transmission device 2 drives the shoe upper to move. During the movement, the three-axis driving device I3 can drive the data acquisition device 4 to move in three-dimensional space, so that the data acquisition device 4 can collect data. After the collection is completed, the transmission device 2 drives the shoe upper to move to the marking device 6, and the three-axis driving device II can drive the marking device 6 to move in three-dimensional space. The marking device 6 marks the unqualified position points.

[0040] Therefore, through the three-axis drive device I3, the three-axis drive device II and the transmission device 2 of the utility model, the qualified position points can be finally marked out, eliminating the process of manual marking and improving efficiency. In addition, the three-axis drive device I3 can drive the data acquisition device 4, and the three-axis drive device II can drive the marking device 6 to move in three-dimensional space, which can greatly reduce false detection and missed detection and improve the yield of the product.

[0041] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
