The four micro-guide rail sliders 31 are divided into two groups, each group is equipped with a centering connecting plate 32, and the two centering connecting plates 32 are arranged in an oblique symmetrical manner. A push plate 33 is installed at the end of each of the two centering connecting plates 32 for position calibration of the single and double modules, and a gear is installed on the inner side of each of the two centering connecting plates 32. The rack 34 is provided with a gear 35 in the middle of the rack 34, the gear 35 is meshed with the two racks 34, and a first servo electric push rod (not shown in the figure) is also installed on the base plate 1. When the first servo electric push rod is started, the first servo electric push rod can push any centering connecting plate 32 to move away from the gear 35, and the moving centering connecting plate 32 drives the other centering connecting plate 32 to move in the opposite direction through the rack 34 and the gear 35, so as to realize that the two push plates 33 move to the left and right sides of the support plate 2 at the same time. The distance between the push plates 33 can be adjusted accordingly according to the actual use requirements, so as to calibrate the position of the single and double modules on the support plate 2.

[0029] Furthermore, the tray centering mechanism 3 also includes two slide rails 36 , a slider 37 and a connecting block 38 .

The spring 54 is arranged between the shift block 53 and the inner wall of the fixed seat 51, and the second servo electric push rod is arranged on the base plate 1 for pushing the shift block 53.

[0034] The tray unlocking mechanism 5 mainly consists of a fixing seat 51, a positioning pin 52, a shifting block 53, a spring 54 and a second servo electric push rod (not shown in the figure). The fixing seat 51 is fixedly installed on the bottom plate 1 near the centering connecting plate 32. A groove for installing the positioning pin 52, the shifting block 53 and the spring 54 is opened inside the fixing seat 51. One end of the groove of the fixing seat 51 is connected to the outside. A positioning pin 52 is inserted in the front part of the groove of the fixing seat 51. The head of the positioning pin 52 can extend out of the groove. A shift block 53 is fixedly installed at the tail of 52, and the front end of the shift block 53 is fixedly connected to the positioning, and the tail end of the shift block 53 extends out of the groove, so that the second servo electric push rod can push the shift block 53 to move horizontally along the groove. A notch 321 that matches the head of the positioning pin 52 is opened on the centering connecting plate 32, so that the positioning pin 52 can be inserted into the notch 321 to assist the tray centering mechanism 3 to realize the position calibration of multiple single and double modules. It should be noted that the specific position of the notch 321 can be adjusted according to actual conditions. The invention relates to a method for arranging the plurality of tray assemblies, wherein the plurality of tray assemblies are provided with a plurality of servo-electric push rods 54 and a plurality of servo-electric push rods 56. The plurality of servo-electric push rods 56 are provided with a plurality of servo-electric push rods 57. The plurality of servo-electric push rods 56 are provided with a plurality of servo-electric push rods 57. The plurality of servo-electric push rods 56 are provided with a plurality of servo-electric push rods 57. The plurality of servo-electric push rods 56 are provided with a plurality of servo-electric push rods 57. The plurality of servo-electric push rods 56 are provided with a plurality of servo-electric push rods 57. The plurality of servo-electric push rods 56 are provided with a plurality of servo-electric push rods 57.

[0035] Furthermore, the tray centering mechanism 3 also includes a fixed plate 39, a nitrogen spring 310, a guide plate 311, and a spring connecting plate 312. The fixed plate 39 is arranged on the base plate 1, the nitrogen spring 310 is arranged on the fixed plate 39, the guide plate 311 is arranged on the nitrogen spring 310, and the guide plate 311 is connected to the connecting block 38 through the spring connecting plate 312.

[0036] In this embodiment, fixing plates 39 are installed at positions of the bottom plate 1 near the two slide rails 36, and nitrogen springs 310 are installed on the fixing plates 39. Guide plates 311 are installed on the nitrogen springs 310, so that the nitrogen springs 310 can move along the direction of the guide plates 311. Spring connecting plates 312 are installed on the guide plates 311, and the guide plates 311 are fixedly connected to the connecting blocks 38 through the spring connecting plates 312. In the original state, the connecting blocks 38 are subjected to the elastic force of the nitrogen springs 310, so that the two push plates 33 always remain separated from each other, and after the tray unlocking mechanism 5 completes the unlocking of the tray centering mechanism 3, the nitrogen springs 310 can quickly restore the two push plates 33 to their original state, so as to quickly calibrate the position of the next batch of single and double modules, thereby improving the conveying efficiency of the single and double modules.

[0037] During operation, after the tray reaches the designated workstation, the first servo electric push rod (not shown in the figure) is started, and the first servo electric push rod pushes the centering connecting plate 32 to move in the direction away from the gear 35. The moving centering connecting plate 32 drives the other centering connecting plate 32 to move in the opposite direction through the rack 34 and the gear 35, so that the two push plates 33 can move to the left and right sides of the support plate 2 at the same time. When the centering connecting plate 32 moves to the set position, the positioning pin 52 is inserted into the notch 321 on the centering connecting plate 32 by the elastic force of the spring 54, and the centering connecting plate 32 is locked to prevent the centering connecting plate 32 from shifting during the placement of the single and double modules, thereby further improving the accuracy of the position calibration of the single and double modules by the tray centering mechanism 3. Then, the module gripper grabs the entire group of single and double modules and puts them in turn to complete the position calibration. After alignment, the support plate 2 is then connected to the positive and negative screw rods 42 through the servo motor (not shown in the figure) on the servo clamping station, and the positive and negative screw rods 42 are driven to rotate. The positive and negative screw rods 42 drive the pressure plate 44 to move toward the middle of the positive and negative screw rods 42 through the screw connecting seat 43 to achieve clamping and fixation of the single and double module groups. Finally, the tray is transported to the module assembly station to complete the assembly of the single and double modules. After the assembly is completed, the second servo electric push rod (not shown in the figure) is started to push the shift block 53 to drive the positioning pin 52 to move toward the inner wall direction of the fixing seat 51, so that the head of the positioning pin 52 moves out of the slot 321. At this time, the two push plates 33 are quickly restored to their original state due to the action of the nitrogen spring 310, so as to facilitate the rapid position calibration of the next batch of single and double modules, thereby improving the transportation efficiency of the single and double modules.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
