Description

Technical Field

[0001] The present invention belongs to the field of conveying technology, and specifically relates to a material handling device, and more particularly to a conveying device and a conveying method for SMT patch solar panels. Background Art

[0002] In the SMT (surface mount technology) production line, the docking station is the core equipment for the flow of materials between processes, and is responsible for the temporary storage of solar panels, 90° turning, and multi-station connection.

[0003] In the related art, stop bars are often set around the docking station to limit the solar panels. A gap is set between the inner edge of each stop bar and the outer wall of the solar panel to prevent the solar panel from falling as the docking station rotates. However, when the docking station rotates, the solar panel will shake relative to the docking station, and the outer wall of the solar panel will be damaged due to shaking and friction. Micro cracks on its surface will lead to a decrease in photoelectric efficiency.

[0053] Research has found that in related technologies, in the SMT (surface mount technology) production line, the docking station is the core equipment for the flow of materials between processes, and is responsible for the temporary storage of solar panels, 90° turning and multi-station connection.

[0054] In the related art, stop bars are often set around the docking station to limit the solar panels. A gap is set between the inner edge of each stop bar and the outer wall of the solar panel to prevent the solar panel from falling as the docking station rotates. However, when the docking station rotates, the solar panel will shake relative to the docking station, and the outer wall of the solar panel will be damaged due to shaking and friction. Micro cracks on its surface will lead to a decrease in photoelectric efficiency.

[0055] Therefore, how to prevent the solar panels from shaking when the docking station rotates is a technical problem that needs to be solved urgently in this field.

[0056] The defects in the above solutions and the causes of their occurrence are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0057] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0058] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0059] like Figures 1 to 6 As shown, at least one embodiment provides a conveying device for SMT patch solar panels, including: a conveyor line 1; the conveyor line 1 is horizontally arranged on a workbench, including relatively arranged support frames 11, and a conveyor belt arranged on the inner wall of the support frame 11, and the transmission belt is connected to the conveying motor. An adjusting motor 12 is arranged below the support frame 11, and a slider is threadedly sleeved on the outer wall of the screw shaft of the adjusting motor 12, wherein one of the support frames 11 is fixed on the slider, and the adjusting motor 12 is suitable for driving one support frame 11 to move horizontally relative to the other support frame 11 to adjust the distance between the two support frames 11. A docking station 3 is provided with a accommodating cavity 30 therein, and a plurality of air holes 32 connected to the accommodating cavity 30 are provided on the surface; the docking station 3 is rectangular, and bosses are provided on the four sides of the surface. The arrangement of the bosses prevents the workpiece from falling from the surface of the docking station 3 when the docking station rotates 3 degrees. A gap is provided between the bosses and the edges of the workpiece to facilitate the picking and placing of the workpiece. In SMT production lines, the thickness of solar panels is usually 0.2-0.5mm, and the negative pressure adsorption force needs to reach 5-10kPa to ensure stability.

[0060] Reference Attachment Figure 1 The steering device 2 is located below the docking station 3 and is used to negatively pressure the air in the accommodating chamber 30. The steering device 2 includes a steering cylinder and a steering motor provided at the end of the steering cylinder piston rod. Two movable rods 21 are symmetrically provided at the end of the rotating shaft of the steering motor. The movable rods 21 are adapted to the positioning slots 34, and an air passage connected to the negative pressure air pump is provided in the movable rods 21. When the movable rods 21 are inserted into the positioning slots 34, the negative pressure air pump negatively pressure-suctions the air in the accommodating chamber 30. The two adjustment plates 4 are moved inward by the negative pressure so that the through hole 40 and the air hole 32 are connected, thereby achieving the effect of negative pressure adsorption of the workpiece. At the same time, the inward movement of the two adjustment plates 4 further reduces the length of the docking station when it rotates 3 degrees, thereby preventing the outer ends of the adjustment plates 4 from touching the support frame 11 when the docking station 3 rotates.

[0061] Reference Attachment Figure 2Two adjustment plates 4 are slidably disposed at either end of the docking platform 3's lengthwise direction, used to open and close air holes 32. After the docking platform 3 moves above the steering mechanism 2, the movable rod 21 of the steering mechanism 2 inserts into the bottom wall of the docking platform 3. The steering mechanism 2 negatively draws air from the receiving chamber 30, and the two adjustment plates 4 move toward each other to open the air holes 32, allowing the air holes 32 to negatively absorb and position the workpiece. Several of the air holes 32 are arranged in a matrix, covering more than 90% of the workpiece contact surface. Furthermore, the air holes 32 have a diameter of 2 mm and are spaced 5 mm apart. Through the coordination between the docking platform 3 and the steering mechanism 2, before the docking platform 3 is driven by the steering mechanism 2 to rotate, the movable rod 21 negatively draws air from the receiving chamber 30 of the docking platform 3, causing the two adjustment plates 4 to move inward. This allows the air holes 32 to negatively absorb and position the workpiece, preventing the workpiece from shaking during rotation and improving the stability of the workpiece as it rotates with the docking platform 3. In this embodiment, the workpiece is a patch solar panel.

[0062] Reference Attachment Figure 3 In order to open and close the air hole 32 of the adjustment plate 4, a first spring 301 is provided in the accommodating chamber 30, with its two ends arranged on the inner wall of the accommodating chamber 30 and the side wall of the adjustment plate 4. 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 an angular velocity of 4.5rad / s² to avoid adsorption failure.

[0063] Reference Attachment Figure 5 The bottom wall of the docking platform 3 is provided with two positioning slots 34 adapted to the movable rod 21 of the steering device 2. The positioning slots 34 are connected to the accommodating chamber 30. After the movable rod 21 is inserted into the positioning slots 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 to a negative pressure air pump. After the docking platform 3 is moved above the steering device 2 and the movable rod 21 is inserted into the two positioning slots 34, the steering device 2 drives the docking platform 3 to rotate 3 degrees. The negative pressure air pump uses negative pressure to suck air from the accommodating chamber 30, causing the two adjustment plates 4 to slide inward. Figure 4 The arrow in the figure indicates the inward movement direction of the adjustment plate 4. Furthermore, the outer wall of the adjustment plate 4 is provided with a groove 39, into which the protrusion 38 is adapted to be inserted. 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.

[0064] Reference Attachment Figure 4The adjustment plate 4 is provided with a plurality of through holes 40, which are offset from the air holes 32. When the two adjustment plates 4 are moved toward each other by negative pressure adsorption, the air holes 32 are adapted to negative pressure adsorption to limit the workpiece, preventing the workpiece from shaking when the docking platform 3 rotates. When the adjustment plates 4 are drawn inward by negative pressure, the through holes 40 are connected to the air holes 32.

[0065] Reference Attachment Figure 3 The outer end wall of the adjustment plate 4 has a first limiting groove 41 formed along the width of the docking platform 3. The first limiting groove 41 is adapted to fit within the support frame 11 of the conveyor line 1. When the docking platform 3 is moved 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 as it moves horizontally with the conveyor line 1.

[0066] Reference Attachment Figure 2 The docking platform 3 is slidably mounted on both sides of the platform's width, along which positioning bars 36 are positioned. The outer end wall of the positioning bars 36 defines a second limiting groove 37 along the length of the docking platform 3. The second limiting groove 37 is aligned with the first limiting groove 41 in depth. The provision of the second limiting groove 37 improves the stability of the docking platform 3 and the conveyor line 1 in horizontal movement after the docking platform rotates 3 degrees.

[0067] Reference Attachment 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 bar 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 retracts and moves toward the docking station 3. When the docking station rotates 3 degrees, the adjustment plate 4 and the positioning bar 36 retract 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.

[0068] At least one embodiment provides a conveying device for SMT patch solar panels, including: a docking station 3, which has a accommodating cavity 30 formed therein and a plurality of air holes 32 on the surface of the docking station that are connected to the accommodating cavity 30; two adjustment plates 4, which are slidably arranged at both ends of the docking station 3 in the length direction and have a plurality of through holes 40 corresponding to the air holes 32; the bottom wall of the docking station 3 is provided with two positioning grooves 34 that are connected to the accommodating cavity 30; wherein, after the movable rod 21 of the steering device 2 is inserted into the positioning groove 34, negative pressure sucks the air in the accommodating cavity 30; the two adjustment plates 4 slide inward to connect the air holes 32 with the through holes 40, so as to absorb the limiting workpiece with negative pressure.

[0069] At least one embodiment provides a conveying device for SMT patch solar panels, including: the workpiece moves to the top of the docking station 3, the conveying line 1 drives the docking station 3 to move horizontally 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 station 3, used to drive the docking station to rotate 3 degrees; when the movable rod 21 is negatively sucked, the two adjustment plates 4 move toward each other to open the air hole 32, so that the air hole 32 negatively adsorbs the workpiece.
