[0031] Reference Figures 6 - 9 , the precise positioning device for the processing and emission of electronic components further includes a first right-angle block 83 and a second right-angle block 84. Two centrally symmetric first right-angle blocks 83 that are aligned with its right-angle part 81 are fixedly connected to the top surface of the fixed limiting plate 8. Second right-angle blocks 84 that are aligned with its right-angle part 81 are fixedly connected to the top surface of the movable limiting plate 9; The first right-angle block 83 of one of the workstations is located directly below the intersection of the rear side plate and the bottom of the right side plate of the right-angle plate 3, and the second right-angle block 84 is located directly below the right-angle rod 6; When the synchronous belt 52 rotates, the first right-angle block 83 and the second right-angle block 84 guide the workpiece 50 in the lowermost placement position into the workstation directly below.

[0032] Reference Figure 7 and Figure 9 , the precise positioning device for the processing and emission of electronic components further includes an adjusting mechanism for adjusting the position of the movable limiting plate 9. The adjusting mechanism includes a first guide rail 91, a translation block 92, a nut 93, and a screw rod 94. Two centrally symmetric first guide rails 91 are fixedly connected to the turntable 7. Translation blocks 92 driven by linear motors are slidably connected to the first guide rails 91. The two movable limiting plates 9 slide on the two translation blocks 92 respectively. Nuts 93 are fixedly connected to the translation blocks 92. Screw rods 94 are rotatably connected to the movable limiting plates 9, and the screw rods 94 are threadedly connected to the nuts 93.

[0033] Reference Figure 1 、 Figure 2 、 Figure 7 and Figure 10, the precise positioning device for the processing emissions of electronic components further includes a second guide rail 101, a moving rod 102, and a pusher block 103. The right side of the right side plate of the right-angled plate 3 is fixedly connected to the second guide rail 101. The second guide rail 101 is provided with a moving rod 102 that slides on the X-axis and is driven by a screw motor. The left end of the moving rod 102 bends downward. The lower part of the left end of the moving rod 102 is provided with a pusher block 103 that slides in the Z-axis direction. A compression spring (not shown in the figure) is fixedly connected between the pusher block 103 and the moving rod 102. The right side of the pusher block 103 has an inclined surface 104.

[0034] The support plates 53 on the two synchronous belts 52 are evenly divided into two columns on the left and right. A placement position for temporarily storing the workpieces 50 is formed between the middle two columns of support plates 53. The uppermost placement position is the first placement position. Place a workpiece 50 to be processed in the first placement position. Control the second reduction motor to drive the synchronous pulley 51 to rotate intermittently, so that the left synchronous belt 52 rotates intermittently clockwise and the right synchronous belt 52 rotates intermittently counterclockwise. The support plate 53 rotates together with the synchronous belt 52, thereby driving the workpiece 50 to move down to the second placement position. Continue to place the next workpiece 50 on the first placement position, and so on, until the placement positions are all filled with workpieces 50, so as to centrally place the workpieces 50 and effectively reduce the waiting time.

[0035] At this time, the right rear corner of the workpiece 50 in the placement position fits against the right angle of the right-angled plate 3, and the left front corner of the workpiece 50 fits against the right-angled rod 6. The workpiece 50 in the placement position is limited by the right-angled plate 3 and the right-angled rod 6, so that the position of the workpiece 50 in the placement position on the XY plane is fixed. Control the second reduction motor to rotate the synchronous belt 52 again. Under the guiding action of the first right-angled block 83 and the second right-angled block 84, the workpiece 50 in the lowermost placement position vertically drops into the working position directly below. The four peripheral edges of the workpiece 50 contact the placement part 82, and the middle part of the workpiece 50 is in a suspended state, providing space for the pins of the workpiece 50, so that the workpiece 50 is stably placed in the working position in the left rear.

[0036] Control the first reduction motor to drive the turntable 7 to rotate counterclockwise by 180 degrees, driving the fixed limit plate 8, the moving limit plate 9, the first right-angled block 83, the second right-angled block 84, the adjustment mechanism, and the workpiece 50 in the working position to rotate counterclockwise by 180 degrees to replace the positions of the two working positions, so as to process the workpiece 50 in the right front working position. While processing the workpiece 50, the synchronous belt 52 rotates again. Similarly, the next workpiece 50 drops into the working position in the left rear.

[0037] After the workpiece 50 at the front right working station is processed, control the first reduction motor to rotate the turntable 7, the fixed limit plate 8, the movable limit plate 9, the first right-angle block 83, the second right-angle block 84, the adjustment mechanism and the workpiece 50 in the working station as a whole counterclockwise by 180 degrees again, and continue to process the workpiece 50 at the front right working station. During this process, the processed workpiece 50 in the working station will contact the pushing block 103. The workpiece 50 squeezes the pushing block 103 through the inclined surface 104 to slide upward, compressing the compression spring. When the workpiece 50 passes over the pushing block 103, the compression spring restores, causing the pushing block 103 to move downward and reset; control the linear motor at the rear left working station to drive the translation block 92 to translate forward, driving the movable limit plate 9 and the second right-angle block 84 at the rear left working station to move forward together. Since a row of ball bearings are provided on the placement part 82 of the movable limit plate 9, and the ball bearings play a role in reducing friction, the second right-angle block 84 can smoothly separate from the processed workpiece 50. Control the lead screw motor to drive the moving rod 102 to translate leftward along the second guide rail 101, driving the pushing block 103 to move leftward. The pushing block 103 pushes the workpiece 50 at the rear left out for discharging; control the lead screw motor to move the second guide rail 101 and the pushing block 103 rightward to reset, and control the linear motor at the rear left working station to move the translation block 92, the movable limit plate 9 and the second right-angle block 84 backward to reset, and then the workpiece 50 at the next placement position can fall into the working station through the synchronous belt 52.

[0038] When positioning and processing a workpiece 50 with a larger size is required, manually pull the handle downward to drive the lifting rod 65 to move downward, compressing the return spring, so that both the first limiting part 66 and the second limiting part 67 leave the groove 63. Manually push the first translation plate 4 to move leftward in the X-axis direction. The first translation plate 4 drives the right-angle rod 6, the fixed block 64, the lifting rod 65 and the left conveying part 5 to move leftward together. Manually push the sliding rod 61 to move forward in the Y-axis direction, driving the second translation plate 62, the right-angle rod 6, the fixed block 64 and the lifting rod 65 to move forward together. In this way, the position of the right-angle rod 6 and the left conveying part 5 can be freely adjusted according to the length and width of the workpiece 50, and the distance between the two conveying parts 5 increases. After the position is adjusted, release the handle, and the return spring restores, causing the lifting rod 65 to move upward and reset. The first limiting part 66 is embedded in the groove 63 of the upper second translation plate 62, and the second limiting part 67 is embedded in the groove 63 of the upper first translation plate 4, making the positions of the right-angle rod 6, the first translation plate 4, the second translation plate 62, the right-angle plate 3 and the conveying part 5 relatively fixed again.

[0039] Manually rotate the screw rod 94. Under the cooperation of the screw rod 94 and the nut 93, the two screw rods 94 move away from each other in the X-axis direction, driving the two moving limit plates 9 to move away from each other in the X-axis direction and the two right-angle blocks 84 to move away from each other in the X-axis direction. Control the linear motor to drive the left translation block 92 to move forward and drive the right translation block 92 to move backward. The translation block 92 drives the moving limit plate 9 and the right-angle block 84 to move synchronously, so that the positions of the moving limit plate 9 and the right-angle block 84 can be freely adjusted according to the length and width of the workpiece 50. At this time, the workpiece 50 with a larger size can be loaded, accurately positioned, processed, and unloaded. In this way, the loading and processing operations can be carried out simultaneously at two workstations, effectively reducing the waiting time, and can be flexibly adjusted according to the size of the workpiece 50, with strong process continuity and high automation, effectively improving the processing efficiency.

[0040] Embodiment 2: On the basis of Embodiment 1, referring to Figure 1 , Figure 2 , Figure 7 and Figure 11 , the electronic component processing and emission precise positioning device further includes a connecting frame 111, a connecting rod 112, and a roller 113. There are two centrally symmetric discharge ports 70 on the turntable 7. The left side of the workbench 1 is connected with a connecting frame 111. A row of connecting rods 112 are connected at the discharge port 70 and on the connecting frame 111. Both ends of the connecting rod 112 are rotatably connected with rollers 113. When the pusher block 103 pushes out the processed workpiece 50, the workpiece 50 is pushed onto the rollers 113. The edge of the workpiece 50 contacts the rollers 113, while the middle of the bottom of the workpiece 50 is in a suspended state. The rollers 113 play a role in reducing friction and at the same time prevent the pins at the bottom of the workpiece 50 from being worn.
