[0031] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0032] As Figures 1 to 6As shown, at least one embodiment provides a conveying device for an SMT patch solar panel, comprising: a conveying line 1; the conveying line 1 is horizontally arranged on a workbench, including oppositely arranged support frames 11 and a conveyor belt arranged on the inner side walls of the support frames 11, and the conveyor belt is in transmission connection with a conveying motor. An adjusting motor 12 is arranged below the support frame 11. A slider is sleeved on the outer wall of the screw rod rotating shaft of the adjusting motor 12, and one of the support frames 11 is fixed on the slider. The adjusting motor 12 is adapted to drive one support frame 11 to horizontally move relative to the other support frame 11 to adjust the distance between the two support frames 11. A connecting table 3 has a receiving cavity 30 formed therein, and a plurality of air holes 32 communicating with the receiving cavity 30 are formed on the surface; the connecting table 3 is rectangular, and convex platforms are arranged on the four sides of the surface. The arrangement of the convex platforms prevents the workpiece from falling off the surface of the connecting table 3 when the connecting table 3 rotates. There is a gap between the convex platform and the four edges of the workpiece to facilitate the picking and placing of the workpiece. In the SMT production line, the thickness of the solar panel is usually 0.2 - 0.5 mm, and the negative pressure adsorption force needs to reach 5 - 10 kPa to ensure stability.

[0033] Reference attachment Figure 1 , a turning device 2, which is located below the connecting table 3 and is used for sucking the air in the receiving cavity 30 by negative pressure; the turning device 2 includes a turning cylinder and a turning motor arranged at the end of the piston rod of the turning cylinder. Two movable rods 21 are symmetrically arranged at the end of the rotating shaft of the turning motor. The movable rods 21 are adapted to the positioning grooves 34, and air channels communicating with a negative pressure air pump are formed in the movable rods 21. When the movable rods 21 are inserted into the positioning grooves 34, the negative pressure air pump sucks the air in the receiving cavity 30 by negative pressure, and the two adjusting plates 4 are adsorbed and moved inward by negative pressure, so that the through holes 40 and the air holes 32 are communicated to achieve the effect of limiting the workpiece by negative pressure adsorption. At the same time, the two adjusting plates 4 move inward, further reducing the length when the connecting table 3 rotates, and avoiding the outer ends of the adjusting plates 4 touching the support frame 11 when the connecting table 3 rotates.

[0034] Reference attachment Figure 2, two adjustment plates 4, which are slidably arranged at both ends of the length direction of the docking platform 3, are used to open and close the air holes 32; wherein, after the docking platform 3 moves to the top of the steering device 2, the movable rod 21 of the steering device 2 is inserted into the bottom wall of the docking platform 3; the steering device 2 negatively sucks the air in the receiving chamber 30, and the two adjustment plates 4 move toward each other to open the air holes 32, so that the air holes 32 negatively adsorb the limiting workpiece. Several of the air holes 32 are arranged in a matrix and cover more than 90% of the contact surface of the workpiece; further, the diameter of the air holes 32 is 2mm and is distributed at a spacing of 5mm. Through the cooperation between the docking platform 3 and the steering device 2, before the docking platform 3 is driven by the steering device 2 to rotate, the movable rod 21 negatively sucks the air in the receiving chamber 30 of the docking platform 3, so that the two adjustment plates 4 move inward, so that the air holes 32 can negatively adsorb the limiting workpiece, prevent the workpiece from shaking when rotating, and improve the stability of the workpiece rotating with the docking platform 3.

The first spring 301 is suitable for pushing the adjustment plate 4 to slide outward. When the movable rod 21 negatively sucks the air in the accommodating chamber 30, the negative pressure suction force applied by the negative pressure air pump is greater than the elastic force of the first spring 301, so that the two adjustment plates 4 can move inward synchronously. The adsorption force of the negative pressure air pump is 8-12kPa. Furthermore, the adsorption force of the negative pressure air pump is set to 10kPa. After testing, it can stably adsorb solar panels with a rotation angular velocity of 4.5rad / s² to avoid adsorption failure.

[0036] Reference Figure 5 The bottom wall of the docking platform 3 is provided with two positioning grooves 34 adapted to the movable rod 21 of the steering device 2, and the positioning grooves 34 are connected with the accommodating chamber 30; after the movable rod 21 is inserted into the positioning grooves 34, the steering motor drives the movable rod 21 to rotate, which is suitable for driving the docking platform to rotate 3 degrees. The movable rod 21 is connected with the negative pressure air pump. The docking platform 3 moves to the top of the steering device 2, and after the movable rod 21 is inserted into the two positioning grooves 34, the steering device 2 drives the docking platform 3 to rotate °; the negative pressure air pump negatively sucks the air in the accommodating chamber 30 to make the two adjustment plates 4 slide inward. Figure 4 The arrow in the figure indicates the inward movement direction of the adjustment plate 4. Furthermore, a groove 39 is provided on the outer wall of the adjustment plate 4, and the protrusion 38 is suitable for being inserted into the groove 39; when the two adjustment plates 4 move inward, the inner wall of the groove 39 abuts against the outer wall of the movable rod 21, further improving the stability of the movable rod 21 when plugged into the docking station 3.

[0037] Reference Figure 4The adjusting plate 4 is provided with a plurality of through holes 40, which are staggered with the air holes 32; the two adjusting plates 4 are moved toward each other by negative pressure adsorption, and when the through holes 40 are connected with the air holes 32, the air holes 32 are suitable for negative pressure adsorption to limit the workpiece, so as to prevent the workpiece from shaking when the docking platform 3 rotates. When the adjusting plate 4 is sucked inward by negative pressure, the through holes 40 are connected with the air holes 32.

[0038] Reference Figure 3 The outer end wall of the adjustment plate 4 is provided with a first limiting groove 41 along the width direction of the docking platform 3, and the first limiting groove 41 is adapted to the support frame 11 of the conveyor line 1; wherein, when the docking platform 3 moves onto the conveyor line 1, the side wall of the support frame 11 is adapted to be inserted into the first limiting groove 41. The provision of the first limiting groove 41 improves the stability of the adjustment plate 4 when it moves horizontally with the conveyor line 1.

[0039] Reference Figure 2 The two sides of the docking platform 3 in the width direction are slidably provided with positioning strips 36, and the outer end wall of the positioning strip 36 is provided with a second limiting groove 37 along the length direction of the docking platform 3, and the second limiting groove 37 has the same groove depth as the first limiting groove 41. The provision of the second limiting groove 37 improves the stability of the horizontal movement of the docking platform 3 and the conveyor line 1 after the docking platform rotates 3 degrees.

[0040] Reference Figure 6 In order to reduce the resistance when the docking station 3 rotates, a protrusion 38 is provided at the inner end of the positioning strip 36, and a side wall of the protrusion 38 is provided with an inclined surface; Figure 6 The middle arrow f2 indicates the inward movement direction of the positioning bar 36; f1 indicates the movement direction of the adjustment plate 4. The outer wall of the adjustment plate 4 is provided with a groove 39, and the protrusion 38 is suitable for being inserted into the groove 39; wherein, when the two adjustment plates 4 move toward each other, the positioning bar 36 shrinks and moves toward the docking platform 3. When the docking platform rotates 3 degrees, the adjustment plate 4 and the positioning bar 36 shrink and move inward synchronously, thereby avoiding touching the support frame 11 of the conveyor line 1 during the rotation process. The adjustment plate 4 is provided with a third limiting groove 42 near the positioning groove 34, and the third limiting groove 42 is adapted to the movable rod 21; wherein, the two adjustment plates 4 move toward each other until they abut against the movable rod 21 to clamp the limiting movable rod 21.
