[0038] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can also be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] The embodiment of the present application provides an automatic gluing production line for a crystal rod, which is used for gluing and curing a crystal rod 61, an adhesive plate, and a crystal support 62. Figure 1 , which shows a schematic layout diagram of the automatic gluing production line for the crystal rod of the embodiment of the present application, the automatic gluing production line includes a crystal rod conveying line 71, an adhesive plate conveying line 72, a crystal tray conveying line 73, a gluing device 74, a transfer device and an in-situ pre-curing station 31; the crystal rod conveying line 71 is used to convey the crystal rod 61, the adhesive plate conveying line 72 is used to convey the adhesive plate, the crystal tray conveying line 73 is used to convey the crystal tray 62, and the adhesive plate conveying line 72 and the crystal tray conveying line 73 are both connected to the gluing device 74; the gluing device 74 is used to glue the adhesive plate and the crystal tray 62; the transfer device is used to move the glued adhesive plate, the glued crystal tray 62, and the crystal rod 61 to the in-situ pre-curing station 31, and the crystal rod 61, the glued adhesive plate, and the glued crystal tray 62 are bonded and pre-cured at the in-situ pre-curing station 31.

[0040] The working process of the adhesive automated production line of the embodiment of the present application is as follows: the adhesive plate conveying line 72 conveys the adhesive plate to the gluing device 74, the crystal tray conveying line 73 conveys the crystal tray 62 to the gluing device 74, and the gluing device 74 applies glue to the adhesive plate and the crystal tray 62; the glued adhesive plate and the crystal tray 62 are moved out of the gluing device 74 to the transfer device. The crystal rod conveying line 71 conveys the crystal rod 61 to the transfer device. The transfer device moves the crystal rod 61, the glued adhesive plate and the crystal tray 62 to the in-situ pre-curing station 31, and the crystal rod 61, the glued adhesive plate and the crystal tray 62 are bonded and pre-cured at the in-situ pre-curing station 31.

[0041] In the glue automated production line of the embodiment of the present application, the crystal rod 61, the glued glue plate, and the glued crystal tray 62 are bonded and pre-cured at the in-situ pre-curing station 31. The bonding and pre-curing of the crystal rod 61, the glued glue plate, and the glued crystal tray 62 are all carried out at the same position. The crystal rod 61, the glued glue plate, and the glued crystal tray 62 do not move from bonding to completion of pre-curing, which can avoid the risk of deflection due to movement and improve the glue pass rate.

[0042] Optional, see Figure 2 As shown, the adhesive automated production line also includes a truss 50, and there are multiple in-situ pre-curing stations 31, and one truss 50 is arranged corresponding to the multiple in-situ pre-curing stations 31; the transfer device is movably arranged on the truss 50 to move the glue-coated adhesive board, the glue-coated crystal support 62, and the crystal rod 61 to the in-situ pre-curing station 31 corresponding to the truss 50.

[0043] The pre-curing of the crystal rod 61, the adhesive plate, and the crystal tray 62 requires a certain amount of time, for example, several hours of pre-curing. When there are multiple in-situ pre-curing stations 31 in the embodiment of the present application, the influence of the pre-curing time of the crystal rod 61, the adhesive plate, and the crystal tray 62 on the production rhythm can be avoided, thereby effectively improving the production capacity of the viscose automated production line.

[0044] Here, the term "plurality" refers to a natural number of two or more. For example, "plurality" of the in-situ pre-curing stations 31 means that the in-situ pre-curing stations 31 have two, three, fifty, etc. The specific number of the in-situ pre-curing stations 31 can be set according to the use requirements.

[0045] Optionally, the crystal rod conveyor line 71 includes at least two sub-conveyor lines, and each of the trusses 50 and the glue coating device 74 has at least two; the sub-conveyor lines, trusses 50, and the glue coating device 74 are arranged in a one-to-one correspondence. A truss 50 and a plurality of in-situ pre-curing stations 31 corresponding to the truss 50 form a pre-curing area. When there are at least two trusses 50, the viscose automated production line has at least two mutually independent pre-curing areas. The sub-conveyor lines and the glue coating device 74 are arranged in a one-to-one correspondence with the trusses 50, that is, the sub-conveyor lines and the glue coating device 74 are arranged in a one-to-one correspondence with the pre-curing areas. The sub-conveyor lines convey the crystal rods 61 to the corresponding pre-curing areas, and the glue coating device 74 conveys the glued adhesive board and the crystal support 62 after being glued to the corresponding pre-curing areas. The layout is reasonable and can meet the production rhythm and capacity requirements in the viscose automated production line.

[0046] Further, in a specific example, referring to Figure 2 As shown, the crystal rod conveying line 71 includes three sub-conveying lines, and there are three trusses 50 and three glue coating devices 74. The three sub-conveying lines, the three trusses 50, and the three glue coating devices 74 are arranged in a one-to-one correspondence.

[0047] Here, at least two or at least two refers to natural numbers of two or more. For example, the crystal rod conveying line 71 includes at least two sub-conveying lines, which means that the crystal rod conveying line 71 includes two conveying lines, three conveying lines, etc.

[0048] Optionally, the sub-conveyor lines include a stick assembly sub-conveyor line 76 and a fixed-length stick conveyor line 75.

[0049] In the embodiment of the present application, the crystal rods 61 are classified in the crystal rod conveyor line 71 and conveyed to the splicing rod conveyor line 76 and the fixed-length rod conveyor line 75 respectively. On the one hand, it corresponds to the different flow times of the splicing rods and the fixed-length rods, and reserves more interval time for the splicing rods; on the other hand, it corresponds to the subsequent at least two trusses 50, and realizes pre-curing in at least two pre-curing areas.

[0050] Optionally, the transfer device includes a loading robot and a unloading robot, both of which are movably arranged on the truss 50; the loading robot is used to move the glue-coated adhesive board, the glue-coated crystal tray 62, and the crystal rod 61 to the in-situ pre-curing station 31; the unloading robot is used to move the pre-cured crystal rod 61, the adhesive board and the crystal tray 62 out of the in-situ pre-curing station 31.

[0051] In the transfer device of the embodiment of the present application, the loading manipulator is used for loading the crystal rod 61, the adhesive plate after gluing, and the crystal tray 62 after gluing, and the unloading manipulator is used for unloading the pre-cured three-in-one crystal rod assembly 63 (referring to the pre-cured combination product of the crystal rod 61, the adhesive plate, and the crystal tray 62). The loading manipulator and the unloading manipulator are used for loading and unloading, respectively, which can improve the efficiency of loading and unloading, thereby improving the production capacity of the viscose automated production line.

[0052] Optionally, the in-situ pre-curing station 31 is provided with a pressing block storage section 37, which is used to store pressing blocks 38; the transfer device is also used to place the pressing blocks 38 on the crystal rod 61 in the in-situ pre-curing station 31, and the pressing blocks 38 are used to press down the crystal rod 61, adhesive plate, and crystal support 62 that are pre-cured in the in-situ pre-curing station 31.

[0053] In the embodiment of the present application, the loading robot in the transfer device is used to place the pressing block 38 on the crystal rod 61 in the in-situ pre-curing station 31, and the unloading robot is used to take the pressing block 38 off the three-in-one crystal rod assembly 63 after pre-curing. At this time, the working process of the transfer device is that after the loading robot moves the crystal rod 61, the adhesive plate after gluing, and the crystal tray 62 after gluing to the in-situ pre-curing station 31, the loading robot places the pressing block 38 on the crystal rod 61 located in the in-situ pre-curing station 31. After the pressing block 38 is placed on the crystal rod 61, the crystal rod 61, the adhesive plate and the crystal tray 62 are pre-cured for several hours in the in-situ pre-curing station 31. After the pre-curing of the crystal rod 61, the adhesive plate and the crystal tray 62 is completed, the unloading robot takes the pressing block 38 off the three-in-one crystal rod assembly 63, and then moves the three-in-one crystal rod assembly 63 out of the in-situ pre-curing station 31.

[0054] The in-situ pre-curing station 31 is provided with a block storage part 37, which is used to store the blocks 38 and to temporarily store the blocks 38 during startup and line cleaning operations. The transfer device is used to move the blocks 38 on the block storage part 37 to the in-situ pre-curing station 31 provided with the block storage part 37, so as to realize the nearby movement of the blocks 38, which can effectively save the time spent on placing and taking the blocks 38, thereby improving the production rhythm and capacity requirements of the viscose automated production line.

[0055] Optionally, the viscose automated production line further includes an in-situ pre-curing device 30 , and the in-situ pre-curing device 30 is provided with at least one in-situ pre-curing station 31 .

[0056] In the embodiment of the present application, an in-situ precuring device 30 is provided with an in-situ precuring station 31 to realize the modularization of the in-situ precuring station 31. The in-situ precuring station 31 can be increased or decreased by moving the in-situ precuring device 30, and the in-situ precuring station 31 can be quickly and reasonably arranged.

[0057] Here, at least one refers to one or more natural numbers, for example, an in-situ pre-curing station 31 is provided on the in-situ pre-curing device 30; for example, referring to Figure 3 As shown, the in-situ pre-curing device 30 is provided with two in-situ pre-curing stations 31 ; for another example, the in-situ pre-curing device 30 is provided with five in-situ pre-curing stations 31 .

[0058] Optionally, when the transfer device moves the glue-coated adhesive plate, the glue-coated crystal tray 62, and the crystal rod 61 to the in-situ pre-curing station 31 of the in-situ pre-curing equipment 30, the crystal rod 61 and the crystal tray 62 are in an unbonded and unaligned state, and the in-situ pre-curing equipment 30 can align the crystal rod 61 and the crystal tray 62, so that the centering accuracy of the crystal rod 61 and the crystal tray 62 in the three-in-one crystal rod assembly 63 after bonding and pre-curing is high.

[0059] Optional, see Figures 3 to 5 As shown, the in-situ pre-curing equipment 30 includes a three-in-one centering platform 32 , a crystal tray centering cylinder 33 , an adhesive plate centering cylinder 34 , a crystal rod centering cylinder 35 , a crystal tray pushing cylinder 36 , a pressing block storage unit 37 and a pre-curing rack 39 .

[0060] Among them, the three-in-one centering platform 32, the crystal tray centering cylinder 33, the adhesive plate centering cylinder 34, the crystal rod centering cylinder 35, the crystal tray pushing cylinder 36 and the block storage part 37 are all arranged on the pre-curing frame 39. The three-in-one centering platform 32 is used to place the crystal rod 61, the adhesive plate and the crystal tray 62, and the crystal rod 61, the adhesive plate and the crystal tray 62 are centered, bonded and pre-cured on the three-in-one centering platform 32.

[0061] Reference Figure 4As shown, there are four crystal support centering cylinders 33, adhesive plate centering cylinders 34 and crystal rod centering cylinders 35, two crystal support centering cylinders 33, two adhesive plate centering cylinders 34 and two crystal rod centering cylinders 35 are arranged on the left side of the three-in-one centering platform 32, and the other two crystal support centering cylinders 33, the other two adhesive plate centering cylinders 34 and the other two crystal rod centering cylinders 35 are arranged on the right side of the three-in-one centering platform 32. Of the two crystal support centering cylinders 33 located on the same side of the three-in-one centering platform 32, one is close to the upper end of the three-in-one centering platform 32, and the other is close to the lower end of the three-in-one centering platform 32. Of the two adhesive plate centering cylinders 34 located on the same side of the three-in-one centering platform 32, one is close to the upper end of the three-in-one centering platform 32, and the other is close to the opposite lower end of the three-in-one centering platform 32. Of the two crystal ingot centering cylinders 35 located on the same side of the three-in-one centering platform 32 , one is close to the upper end of the three-in-one centering platform 32 , and the other is close to the relatively lower end of the three-in-one centering platform 32 .

[0062] The crystal tray pushing cylinder 36 is disposed at one end of the three-in-one centering platform 32 and is used to push the crystal tray 62 to move on the three-in-one centering platform 32 to contact the baffle (not shown) of the in-situ pre-curing device 30. Figure 6 and Figure 7 , all show the position schematic diagrams of the crystal tray centering cylinder 33, the adhesive plate centering cylinder 34, the crystal rod centering cylinder 35, the crystal tray pushing cylinder 36, and the three-in-one crystal rod assembly 63.

[0063] When the in-situ pre-curing device 30 is working, the loading robot places the crystal rod 61, the glued adhesive board and the crystal tray 62 coated with glue on the three-in-one centering platform 32, and the four crystal tray centering cylinders 33 are started. Figure 4 The crystal support 62 is pushed in the left and right directions to move to the middle of the three-in-one centering platform 32 for centering correction. The crystal support push cylinder 36 is started. Figure 4 The crystal support 62 is pushed toward the baffle in the up and down directions; the four adhesive plates are centered by the cylinder 34 and the Figure 4 The adhesive plate is pushed in the left and right directions to move to the middle of the three-in-one centering platform 32 for centering correction; the four crystal rod centering cylinders 35 are started. Figure 4 The crystal rod 61 is pushed in the left and right directions to move to the middle of the three-in-one centering platform 32 for centering correction; the crystal rod 61, the adhesive plate and the crystal support 62 are in a centering state, and in the centering state, the crystal rod 61, the adhesive plate and the crystal support 62 are bonded and pre-cured. It can be understood that the start timing of the crystal support centering cylinder 33, the adhesive plate centering cylinder 34, the crystal rod centering cylinder 35 and the crystal support pushing cylinder 36 can be set according to demand. For example, the crystal support centering cylinder 33 is started after the crystal support 62 is placed on the three-in-one centering platform 32; the crystal support centering cylinder 33 is started after the adhesive plate is placed on the crystal support 62; for another example, the crystal support centering cylinder 33 is started after the crystal rod 61 is placed on the adhesive plate.

[0064] The in-situ pre-curing device 30 of the embodiment of the present application realizes the centering, bonding and in-situ pre-curing of the crystal rod 61, the adhesive plate and the crystal tray 62. The crystal rod 61, the adhesive plate and the crystal tray 62 are placed on the three-in-one centering platform 32 and after the centering is achieved, the crystal rod 61, the adhesive plate and the crystal tray 62 no longer make relative movement, which reduces the risk of deflection caused by movement, improves the centering of the crystal rod 61 and the crystal tray 62, and greatly improves the qualified rate of bonding; and avoids the influence on the subsequent slicing process, thereby improving the finished product rate of the crystal rod 61 slices.

[0065] Optionally, since the alignment of the silicon rod and the crystal tray 62 in the gluing process has a direct impact on the subsequent slicing yield of the crystal rod 61, in order to ensure the smooth progress of the subsequent slicing work and avoid the flow of unqualified products into the subsequent slicing process, the gluing automation production line also includes a centering detection device 10. At this time, the transfer device in the gluing automation production line is also used to move the pre-cured crystal rod 61, the gluing plate and the crystal tray 62 to the centering detection device 10, and the centering detection device 10 is used to detect the centering of the crystal rod 61, the gluing plate and the crystal tray 62.

[0066] The centering detection device 10 of the embodiment of the present application is used to detect the centering of the crystal rod 61, the adhesive plate and the crystal tray 62, realize the automatic centering detection of the silicon rod and the crystal tray 62, and make the three-in-one crystal rod assembly 63 that has passed the centering detection flow out of the adhesive automatic production line. When the three-in-one crystal rod assembly 63 that has passed the centering detection is sent to the slicer of the slicing process for slicing, it can avoid the problem that the tension of the diamond wire in the front and rear directions is inconsistent, and the diamond wire on the side with large tension is easy to break, thereby causing a greater impact on the slicing; and avoid the problem that the rod material at both ends of the crystal rod 61 cannot be normally sliced ​​after cutting, thereby causing waste of silicon material and reducing the effectiveness of slicing.

[0067] Of course, the centering detection device 10 is not limited to detecting the centering of the crystal rod 61 and the crystal support 62, and can also detect the centering between other components. The embodiment of the present application does not specifically limit the application of the centering detection device 10.

[0068] Optional, see Figure 2 As shown, the centering detection device 10 includes a clamping mechanism, a first driving component 12 and a centering detection element; the clamping mechanism is used to clamp the crystal holder 62; the first driving component 12 is connected to the centering detection element, driving the centering detection element to move parallel to the crystal holder 62, and the centering detection element is used to detect the displacement of the crystal rod 61 to obtain the centering of the crystal rod 61.

[0069] Further references Figure 8As shown, the clamping mechanism includes a first support frame 11, a second support frame 17, and a second driving assembly. The second driving assembly is connected between the first support frame 11 and the second support frame 17. The second driving assembly drives the first support frame 11 and the second support frame 17 to move toward or away from each other; the first support frame 11 and the second support frame 17 move toward each other to clamp the crystal holder 62 to fix the crystal holder 62.

[0070] The first driving component 12 is connected to the first supporting frame 11 and / or the second supporting frame 17. The first driving component 12 drives the centering detection element 121 to move parallel to the crystal support 62, so that the position of the centering detection element 121 relative to the crystal support 62 is fixed during the detection process, thereby achieving the purpose of detecting the side wall displacement of the crystal rod 61 with the crystal support 62 as a reference.

[0071] In the embodiment of the present application, the alignment detection device 10 can detect the alignment of the crystal rod 61 and the crystal tray 62, and discover in advance the workpieces where the crystal rod 61 and the crystal tray 62 are skewed beyond the standard, so as to avoid the unqualified products of the crystal rod 61 and the crystal tray 62 flowing into the slicer, causing backlash, waste of work time and waste of raw materials, avoid the influence of unqualified products on the slicing yield, and ensure the smooth progress of subsequent slicing work.

[0072] Optionally, the moving direction of the neutral detection element 121 is perpendicular to the moving direction of the first support frame 11. Fig.12 and Fig.13 As shown, considering the length and width of the crystal rod 61 and the crystal tray 62, the first support frame 11 and the second support frame 17 move in the width direction of the crystal rod 61 and the crystal tray 62, and the first support frame 11 and the second support frame 17 clamp and fix the two ends of the crystal tray 62 in the width direction. The neutral detection element 121 moves in the length direction of the crystal rod 61, and the relative offset of the crystal rod 61 and the crystal tray 62 is obtained in the length direction. Compared with obtaining the relative offset of the crystal rod 61 and the crystal tray 62 in the width direction, it has the advantage of being more accurate because the length in the length direction is greater than the length in the width direction.

[0073] Optional, see Figure 4 and Fig.10 As shown, the neutralization detection device 10 also includes a first guide rail 130, which is connected to the first support frame 11 and / or the second support frame 17 and is arranged perpendicular to the moving direction of the first support frame 11; the neutralization detection element 121 is arranged on the first guide rail 130, and the first driving component 12 drives the neutralization detection element 121 to move on the first guide rail 130.

[0074] When the first guide rail 130 is connected to the first support frame 11 or the second support frame 17, one centering detection element 121 detects the centering of the crystal ingot 61. When there are two first guide rails 130, one first guide rail 130 is connected to the first support frame 11, and the other first guide rail 130 is connected to the second support frame 17, two centering detection elements 121 detect the centering of the crystal ingot 61, which has the advantage of more accurate detection.

One end of the drag chain 128 is fixed to the drag chain mounting plate 127 by fasteners such as screws, and the other end of the drag chain 128 is fixed to the mounting base plate 122 by fasteners such as screws. The drag chain 128 is used to restrain cables or wires to provide protection for the cables or wires.

[0076] Optionally, the centering detection element 121 is a displacement sensor, which obtains the displacement of the side wall of the crystal rod 61 during movement; when the displacement of the side wall of the crystal rod 61 is within a preset deviation range, it is determined that the centering of the crystal support 62 and the crystal rod 61 is qualified.

[0083] 17 collides with the crystal support 62.

[0084] Further references Figure 8 As shown, the detection frame 13 includes a foot cup 131, a caster 132, a fixed seat 133 and a centering detection platform 134. The centering detection platform 134 is arranged at the upper end of the detection frame 13, and the foot cup 131, the caster 132 and the fixed seat 133 are all arranged at the lower end of the detection frame 13. The detection frame 13 can be moved by the caster 132, which is convenient for the movement of the detection frame 13.

[0085] Optionally, the neutrality detection device 10 also includes a conveyor line 15, part of which is arranged between the first support frame 11 and the second support frame 17. The conveyor line 15 is used to convey the crystal holder 62 and the crystal rod 61 to or move them between the first support frame 11 and the second support frame 17, so as to perform a neutrality detection on the neutrality detection device 10, and to remove the crystal holder 62 and the crystal rod 61 after the neutrality detection is completed.

[0086] In the embodiment of the present application, the working process of the neutral detection device 10 is as follows: Fig.12 and Fig.13 shown.

[0087] The conveyor line 15 conveys the three-in-one crystal rod assembly 63 to enter between the first support frame 11 and the second support frame 17. When the position sensor 16 detects that the three-in-one crystal rod assembly 63 has reached the detection position, the conveyor line 15 stops moving, and the second driving mechanism 143 is activated at the same time. The second driving mechanism 143 drives the first support frame 11 and the second support frame 17 to move toward each other, and the crystal holder 62 is stuck in the two slot-like structures 116. The side wall of the crystal holder 62 is tightly attached to the slot wall of the slot-like structure 116 to fix the crystal holder 62. Then, the first driving mechanism 129 drives the displacement sensor to move, and the displacement sensor obtains the displacement of the side wall of the crystal rod 61 during the movement; when the displacement of the side wall of the crystal rod 61 is within the preset deviation range, it is judged that the centering of the crystal holder 62 and the crystal rod 61 is qualified; when the displacement of the side wall of the crystal rod 61 exceeds the preset deviation range, it is judged that the centering of the crystal holder 62 and the crystal rod 61 is unqualified. After the centering detection is completed, the conveyor line 15 starts to move the three-in-one crystal rod assembly 63 out of the centering detection device 10, and the unqualified three-in-one crystal rod assembly 63 is treated as an unqualified product. This can avoid the impact of the unqualified centering of the crystal rod 61 and the crystal support 62 on the slicing yield rate and ensure the smooth progress of subsequent slicing work.

[0088] Optionally, the automatic glue production line further includes a static storage 80. After the three-in-one crystal rod assembly 63 flows out from the centering detection device 10, it enters the static storage 80 and is kept still for several hours, and then is transported to the slicing process.

[0089] Optionally, in a specific embodiment, the working process of the automatic gluing production line of the crystal rod in the embodiment of the present application is as follows:

[0090] The crystal rod 61 is loaded and inspected at the crystal rod 61 loading / inspection station. The crystal rod 61 will also pass through the microwave heating station during the transportation of the crystal rod conveyor line 71. The microwave heating station performs microwave heating on the crystal rod 61 to ensure that the crystal rod 61 is in a reasonable temperature range during bonding. Then, the crystal rod 61 is divided according to the length, and the crystal rod 61 is transported to the transfer device through the splicing rod conveyor line 76 or the fixed length rod conveyor line 75.

[0091] During the process of being transported on the wafer tray conveyor line 73 , the wafer tray 62 will pass through a wafer tray incoming material dust removal station, which cleans the surface of the wafer tray 62 .

[0092] During the conveying process of the adhesive board on the adhesive board conveying line 72, the adhesive board will pass through the adhesive board loading cleaning station, and the adhesive board loading cleaning station will clean the upper and lower surfaces of the adhesive board.

[0093] The adhesive plate conveying line 72 conveys the adhesive plate to the gluing device 74, and the crystal tray conveying line 73 conveys the crystal tray 62 to the gluing device 74. The gluing device 74 applies glue to the adhesive plate and the crystal tray 62. The glued adhesive plate and the glued crystal tray 62 are conveyed to the two-in-one bonding equipment, and the glued adhesive plate and the glued crystal tray 62 are bonded in the two-in-one bonding equipment.

[0094] The loading robot moves the bonded adhesive plate and the crystal holder 62 to the in-situ pre-curing station 31 of the in-situ pre-curing device 30 , and then moves the crystal rod 61 to the adhesive plate of the in-situ pre-curing station 31 .

[0095] The crystal tray centering cylinder 33, adhesive plate centering cylinder 34, crystal rod centering cylinder 35, and crystal tray pushing cylinder 36 in the in-situ pre-curing equipment 30 are started to ensure the centering accuracy of the crystal rod 61, adhesive plate and crystal tray 62, and enable the crystal rod 61, adhesive plate and crystal tray 62 to be bonded and pre-cured with high centering accuracy.

[0096] The unloading robot moves the three-in-one crystal rod assembly 63 (referring to the combined product of the crystal rod 61, the adhesive plate and the crystal tray 62 after pre-curing) from the in-situ pre-curing station 31 to the conveyor line 15, and the three-in-one crystal rod assembly 63 enters the centering detection device 10 for centering detection. When the centering deviation of the crystal rod 61 and the crystal tray 62 in the three-in-one crystal rod assembly 63 is within the preset deviation range, the three-in-one crystal rod assembly 63 is judged to be a qualified product, and the three-in-one crystal rod assembly 63 is conveyed to the static warehouse 80. When the centering deviation of the crystal rod 61 and the crystal tray 62 in the three-in-one crystal rod assembly 63 exceeds the preset deviation range, the three-in-one crystal rod assembly 63 is judged to be an unqualified product, and the unqualified product is subjected to subsequent unqualified product processing.

[0097] In the glue automated production line of the embodiment of the present application, the crystal rod 61, the glued glue plate, and the glued crystal tray 62 are bonded and pre-cured at the in-situ pre-curing station 31. The bonding and pre-curing of the crystal rod 61, the glued glue plate, and the glued crystal tray 62 are all carried out at the same position. The crystal rod 61, the glued glue plate, and the glued crystal tray 62 do not move from bonding to completion of pre-curing, which can avoid the risk of deflection caused by movement, improve the glue pass rate, and effectively ensure the smooth progress of subsequent slicing.

[0098] Moreover, the workstations of each process of the viscose automated production line are modularized. When planning different sites and production capacities of the base, they can be quickly and reasonably combined and arranged to provide a layout that meets the production capacity and site requirements.
