DETAILED DESCRIPTION

[0027] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments to make the advantages and features of the present invention easier for those skilled in the art to understand. Obviously, the embodiments described in this application are only part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0028] See also Figure 1 The illustrated device is used to identify and locate a workpiece 100. The workpiece 100 has a first side surface and a second side surface disposed opposite each other. The first side surface is provided with an identification mark, and the second side surface is provided with two positioning marks spaced apart. The device includes multiple detection mechanisms arranged along a first direction. Each detection mechanism includes an identification member 11 and a positioning detection module. The identification member 11 is movably arranged along the first direction. The positioning detection module includes a fixed detection member 12 and a movable detection member 13 movably arranged along the first direction.

[0029] The identification element 11 is used to scan and read the identification mark on the first side, while the fixed detection element 12 and the mobile detection element 13 are respectively used to read the two positioning marks on the second side. The positioning detection module is connected to the processing system signal. The processing system can determine the state of the workpiece 100 based on the position of the two positioning marks in the images of the fixed detection element 12 and the mobile detection element 13, and determine whether the workpiece 100 needs to be corrected to ensure that the workpiece 100 maintains the correct state before entering the next process. Specifically, in this embodiment, the identification element 11 is a VCR barcode reader lens; the fixed detection element 12 and the mobile detection element 13 are CCD lenses. The identification element 11 obtains the identity information of the workpiece 100 by scanning and reading the identification mark.

[0030] When the identification and positioning device is in operation, the identification member 11 and the positioning detection module are located on opposite sides of the workpiece 100. The first side faces the identification member 11, and the identification mark is located within the detection area of ​​the identification member 11. The second side faces the positioning detection module, and one positioning mark is located within the detection area of ​​the fixed detection member 12, while the other positioning mark is located within the detection area of ​​the mobile detection member 13 of any detection mechanism.

[0031] The identification and positioning device of this embodiment is rich in functions. It has a first working mode and a second working mode in the working state. In the first working mode, each detection mechanism identifies and locates a workpiece 100. The identification and positioning device can use multiple groups of detection mechanisms to simultaneously identify and locate multiple workpieces 100, thereby improving work efficiency. It can also identify and locate the workpiece 100 individually. The identification and positioning device of this embodiment can better adapt to workpieces 100 of different sizes. When identifying and locating larger-sized workpieces 100, the distance between the two positioning marks of the workpiece 100 is usually large. At this time, the identification and positioning device can be converted to the second working mode. In this mode, the fixed detection part 12 of one detection mechanism and the mobile detection part 13 of another detection mechanism can be used to realize the identification of the two positioning marks. In this way, there is no need to reserve too much moving space for the mobile detection part 13 of each detection mechanism, thereby effectively shortening the length of the production line, reducing the space occupied by the identification and positioning device, and reducing production costs.

[0032] In this embodiment, the identification and positioning device also includes a first driving mechanism 41 for driving multiple identification members 11 to move synchronously, and a second driving mechanism 42 for driving multiple mobile detection members 13 to move synchronously. This can reduce the setting of the driving mechanism and thus simplify the structure of the identification and positioning device.

[0033] In this embodiment, the identification and positioning device includes a first guide rail 21 and a second guide rail 22, each extending in a first direction. The identification member 11 is slidably disposed on the first guide rail 21, and the movable detection member 13 is slidably disposed on the second guide rail 22. The first guide rail 21 provides guidance for the movement of the identification member 11, and the second guide rail 22 provides guidance for the movement of the movable detection member 13.

[0034] In this embodiment, the identification and positioning device includes a first mounting frame 31 and a second mounting frame 32. The first mounting frame 31 is slidably mounted on the first guide rail 21, and the second mounting frame 32 is slidably mounted on the second guide rail 22. A plurality of identification members 11 are fixedly mounted on the first mounting frame 31 at intervals, and a plurality of mobile detection members 13 are fixedly mounted on the second mounting frame 32 at intervals. A first drive mechanism 41 is used to drive the first mounting frame 31 to move, and a second drive mechanism 42 is used to drive the second mounting frame 32 to move. Driven by the first drive mechanism 41, the plurality of identification members 11 can move synchronously, and driven by the second drive mechanism 42, the plurality of mobile detection members 13 can move synchronously. This can reduce the number of drive mechanisms and simplify the structure of the identification and positioning device.

[0035] In this embodiment, see Figures 1 to 5As shown, the identification and positioning device is equipped with two detection mechanisms. Along the first direction, fixed detection members 12 and movable detection members 13 are alternately distributed. Specifically, the two fixed detection members 12 are respectively a first fixed detection member 12a and a second fixed detection member 12b, and the two movable detection members 13 are respectively a first movable detection member 13a and a second movable detection member 13b. The first movable detection member 13a and the second fixed detection member 12b are respectively arranged on both sides. The first fixed detection member 12a and the second movable detection member 13b are located between the first movable detection member 13a and the second fixed detection member 12b, and the first fixed detection member 12a is located between the two movable detection members 13.

[0036] See also Figure 1 、 Figure 2 As shown, in this embodiment, the two detection mechanisms can simultaneously identify and locate two workpieces 100. Figure 5 As shown, in this embodiment, the identification and positioning device can also use a detection mechanism to identify and position a workpiece 100. Figure 4 As shown, in this embodiment, when identifying and locating a larger workpiece 100, when the identification and positioning device is in working state, one positioning mark is located in the detection area of ​​the second fixed detection member 12b, and the other positioning mark is located in the detection area of ​​the first movable detection member 13a.

[0037] In this embodiment, the identification and positioning device includes a slide rail 23 extending along a first direction, the first fixed detection member 12a is movably arranged on the slide rail 23, and a locking mechanism for locking the first fixed detection member 12a and the slide rail 23 is provided between the first fixed detection member 12a and the slide rail 23. Figure 4 、 Figure 5 As shown, the position of the first fixed detection member 12 a can be adjusted along the slide rail 23 , thereby adjusting the movable range of the second movable detection member 13 b to accommodate workpieces 100 of different sizes.

[0038] In this embodiment, the identification member 11 is positioned above the positioning and detection module. A transfer space is formed between the identification member 11 and the positioning and detection module in the vertical direction, allowing the workpiece 100 to be transferred along a first direction. In this embodiment, the identification and positioning device includes a transfer mechanism 5 for transferring the workpiece 100 along the first direction. Driven by the transfer mechanism 5, the workpiece 100 is transferred between the identification member 11 and the positioning and detection module. After identification and positioning are completed, the transfer mechanism 5 drives the workpiece 100 away from the identification and positioning device.

[0039] In this embodiment, the transmission mechanism 5 includes a transmission base 51 and a transmission platform 52. The transmission base 51 is arranged to move along a first direction, and the transmission platform 52 is arranged on the transmission base 51 so as to be movable along a horizontal direction. The transmission platform 52 is arranged on the transmission base 51 so as to be rotatable around a rotation center line extending in a vertical direction. Figure 6 As shown, the transport mechanism 5 further includes a transport rail 53 extending in a first direction, and the transport base 51 is slidably disposed on the transport rail 53. In this embodiment, the transport mechanism is signal-connected to the processing system. When the processing system analyzes that the position of the workpiece 100 is deviated and requires correction, the processing system sends a signal to the transport mechanism, and the transport platform 52 can adjust the position of the workpiece 100 by horizontal movement and rotation about the rotation centerline.

[0040] In this embodiment, the workpiece 100 is made of a light-transmitting material. When the workpiece 100 is identified and positioned, the light source of the identification member 11 emits a light beam to the workpiece 100. Since the workpiece 100 is light-transmitting, the light beam will pass through the workpiece 100, causing the positioning mark in the positioning detection module image to become blurred, thereby affecting the normal recognition of the positioning mark by the positioning detection module. Specifically, in this embodiment, the workpiece 100 is light-transmitting glass. In this embodiment, the detection mechanism also includes an auxiliary light source 14, which is located on the same side as the positioning detection module. The auxiliary light source 14 is used to illuminate the positioning mark so that the positioning mark is clear, thereby facilitating recognition by the positioning detection module. In this embodiment, the light output path of the auxiliary light source 14 intersects with the detection path of the fixed detection member 12. When the identification and positioning device is in working condition, a positioning mark is located within the detection area of ​​the fixed detection member 12 and within the illumination area of ​​the auxiliary light source. In some embodiments, the light output path of the auxiliary light source 14 intersects with the detection path of the mobile detection component 13. When the identification and positioning device is in working state, a positioning mark is located in the detection area of ​​the mobile detection component 13 and in the illumination area of ​​the auxiliary light source 14.

[0041] In summary, the identification and positioning device of this embodiment can simultaneously identify and locate multiple workpieces 100 through multiple detection mechanisms, thereby improving work efficiency. Its single detection mechanism can complete the identification and positioning of smaller-sized workpieces 100. When the workpiece 100 is large in size, the fixed detection member 12 of one of the detection mechanisms and the mobile detection member 13 of the other detection mechanism can be used to achieve the positioning of the workpiece 100. In this way, it can be quickly applied to workpieces 100 of different sizes, has a wider range of applicability, and is more convenient and quick to use. At the same time, the two identification members 11 are driven by the first drive mechanism 41, and the two mobile detection members 13 are driven by the second drive mechanism 42, which reduces the setting of the drive mechanism, thereby simplifying the structure of the identification and positioning device.
