Description

Technical Field

[0001] The invention relates to the technical field of solar component transportation, and in particular to a solar component positioning and transportation device. Background Art

[0002] Solar module positioning and conveying equipment is used to accurately convey solar modules from one station to another and position them during the production process of solar modules. It uses automation technology and control systems to ensure the stable movement and accurate position of modules on the production line, thereby improving production efficiency and product quality.

[0003] However, there are still some problems with the existing solar module positioning and conveying equipment: First, when making double-layer glass laminated solar modules, due to the softness and thinness of the EVA film, its four corners are easily drooped naturally due to gravity when the robot uses a suction cup to suck it. When the film is transported to the subsequent processing station, it will cause the corners to fold and bend, thereby damaging the film and affecting its packaging effect. This will not only reduce the efficiency and life of the solar module, but also increase production costs.

[0004] In order to solve this problem, the existing technology introduces support devices such as brackets to support the film. These brackets can keep the film flat during transportation and prevent corners from folding. However, the introduction of brackets increases the complexity of equipment debugging. Each time the film is replaced or adjusted, the position and angle of the bracket need to be precisely adjusted to ensure its support effect. In addition, the support effect of the bracket is also affected by various factors such as manufacturing tolerances and assembly tolerances, which can easily lead to errors in the use of the bracket, thereby exacerbating the folding problem of the film corners. These challenges affect production efficiency and product quality. As a result, the folded corners need to be manually repaired or replaced later, which increases the labor intensity and time cost in the production process. If the folding problem is serious, it may even cause the entire solar panel to be scrapped, resulting in greater waste.

[0005] Secondly, when making double-layer glass laminated solar modules, the staggered placement of film and glass is to ensure the photovoltaic conversion efficiency and durability of the module. This design enables the film to absorb sunlight and convert it into electrical energy, while the glass provides the necessary protection and support. However, when the robot grabs the glass, the film is prone to shifting due to factors such as static electricity between the glass and the film or intermolecular forces and surface tension between the materials. This shift will not only cause the film to be positioned incorrectly in subsequent processing, but also affect the packaging effect, thereby damaging the overall performance of the solar module.

[0006] In order to solve this problem, the existing technology attempts to reduce the risk of film deviation by increasing the moving speed of the robot. In theory, a faster moving speed can shorten the contact time between the robot and the film, thereby reducing the possibility of deviation. However, too fast a moving speed will cause the robot to generate stronger airflow and vibration. These forces can easily carry the film below and make it out of the correct position. When the film is carried away, the wrong position of the film will cause the film and the glass to be loosely packaged, thereby affecting the photoelectric conversion efficiency and durability of the solar module. In addition, if the film is severely deviated, the packaging cannot even be completed, which directly leads to the scrapping of the module.

[0007] To this end, the present invention proposes a solar component positioning and conveying device. Summary of the invention

[0014] Preferably, the receiving seat is installed on an external motor, and the external motor is electrically controlled to start and stop by an external controller. A pressure sensor is installed at the bottom of the first picking device, and the pressure sensor is electrically connected to the external controller. The piston block is elliptical, and the smooth bump group includes a plurality of bumps. The diameter of the circle formed between every two bumps is matched with the diameter of the round rod group, and the edge between every two bumps gradually expands outward, and the bottom of the airflow guide shell gradually expands toward the outside.

[0015] Preferably, the axes of the upper negative pressure hole and the lower negative pressure hole are collinear with the diagonal of the negative pressure generating block, the ratio of the diameters of the upper negative pressure hole and the lower negative pressure hole is 3:5, the inner cavity is composed of a rectangular structure and a rod-shaped structure, the rod-shaped structure is located above the rectangular structure, and the rod-shaped structure is adapted to the shape of the trigger rod.

[0016] Preferably, the two roller conveyors are located in the middle of the storage rack, and the roller conveyors are both electrically controlled to start and stop by an external controller. EVA films and glass are alternately placed on the top of the storage rack. The first picking device and the second picking device both include a slide plate and a lifting plate. The slide plate is slidably connected to the outer surface of the working rack, and the lifting plate is slidably connected to the inside of the slide plate. A driving cylinder 1 is installed on the outer surface of the working rack, and a driving cylinder 2 is installed on the outer surface of the slide plate. The output end of the driving cylinder 1 is fixedly connected to the outer surface of the slide, and the output end of the driving cylinder 2 is fixedly connected to the outer surface of the lifting plate.

[0017] Preferably, a plurality of suction cups are symmetrically and fixedly connected to the bottom of the first picking device in a linear and equidistant arrangement, and the suction cups are all connected to an external negative pressure generator, and the external negative pressure generator is fixedly connected to the top of the lifting plate, and the external negative pressure generator is electrically controlled to start and stop by an external controller, and a pressure sensor is installed at the bottom of the lifting plate, and the pressure sensor is electrically connected to the external controller.

[0018] Preferably, position sensors are installed at the bottom of the first picking device and the second picking device, the position sensors are electrically connected to the external controller, and the position sensors are arranged on a side of the bottom of the first picking device away from the suction cup.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. The gas in the gas cylinder is compressed by the reciprocating motion of the rectangular frame connecting rod, and then the air flow is ejected through the torsion spring to act on the EVA film. The smooth airflow conveying component forms an airflow field above the film based on the aerodynamic principle, and the airflow field will generate an upward lift at the corners of the film, so that the corners of the film are brought together upward, thereby effectively avoiding the natural drooping phenomenon caused by gravity when the robot arm uses a suction cup to absorb. Firstly, through the action of the airflow, the film can remain flat during the conveying process, avoiding folding and bending of the corners, thereby ensuring the stability and reliability of the packaging effect, which is helpful to improve the performance and life of the solar module. Secondly, since the later repair or replacement work caused by the folding of the film corners is reduced, the labor intensity and time cost in the production process are reduced, and the production cost is further reduced.

[0020] Compared with the method of introducing supporting devices such as brackets in the prior art, the introduction of brackets not only increases the complexity of equipment debugging, but also requires precise adjustment of the position and angle of the brackets each time the film is replaced or adjusted, while the smooth airflow conveying component does not require adjustment, which simplifies the conveying process and improves production efficiency. At the same time, the supporting effect of the brackets in the prior art is affected by various factors such as manufacturing tolerances and assembly tolerances, and errors are prone to occur, thereby exacerbating the folding problem of the film corners. The smooth airflow conveying component achieves smooth conveying of the film through airflow control, avoiding these problems and improving the stability and reliability of conveying. Finally, compared with the brackets in the prior art, the smooth airflow conveying component does not require additional hardware investment, thereby reducing production costs. At the same time, since there is no need to frequently adjust and maintain the brackets, maintenance costs are also reduced, and the smooth airflow conveying component is easier to implement.

[0021] The edge between every two protrusions gradually expands outwards, thereby reducing the friction, noise and vibration generated during the transmission between the smooth protrusion group and the round rod group, thereby avoiding slight deviations in the position of the film due to slight transmission vibrations.

[0022] Among them: because the bottom of the airflow guide shell gradually expands outward, the airflow moves from a small angle to a large angle under the guidance of the airflow guide shell, thereby ensuring that the edges and corners of the film can obtain sufficient airflow support and preventing the corner folding problem caused by too small airflow. Secondly, this design can also improve the coverage and uniformity of the airflow, so that the film can remain flatter during the transportation process.

[0023] Among them: with the movement of the rectangular frame connecting rod, one of the two air cylinders exhausts air while the other inhales air, and this periodic intake and exhaust ensures the continuity and stability of the airflow, and prevents excessive bending of the film caused by synchronous intake or exhaust. Secondly, the different airflow states on both sides of the film can prevent the film from being folded during transportation, thereby ensuring the flatness and packaging effect of the film.

[0024] Among them: the elliptical shape enables the piston block to compress the gas more effectively during the reciprocating motion, because the major axis and minor axis of the ellipse will produce different pressure changes during movement, thereby improving the efficiency of gas compression; secondly, the elliptical piston block can produce a more uniform pressure distribution when compressing the gas, which helps to reduce the instability of the airflow and improve the stability of the airflow.

[0025] 2. When the second picking device picks up the glass, the elastic extension of the spring generates a short negative pressure state inside the inner cavity, and the negative pressure state directly acts on the surface of the film through the negative pressure generating block, effectively preventing the film from shifting during the process of the second picking device picking up the glass. The negative pressure stable conveying component not only improves the positioning accuracy of the film in the manufacturing process of solar panels, ensures the tightness of the package between the film and the glass, but also greatly reduces the production loss caused by the displacement of the film. Firstly, through the effect of the negative pressure state, the film can maintain a more stable position during the transportation process, reducing the risk of displacement. Secondly, the adsorption effect of negative pressure reduces the packaging failure and component scrapping caused by film displacement, thereby reducing production costs.

[0026] Compared with the prior art method of attempting to reduce the risk of film deviation by increasing the moving speed of the manipulator, the negative pressure-stabilized conveying assembly uses the negative pressure state to enable the film to maintain a more stable position during the conveying process without relying on the moving speed of the manipulator. The negative pressure-stabilized conveying assembly reduces the impact of airflow and vibration generated by excessive movement speed on the film. At the same time, the negative pressure-stabilized conveying assembly also avoids the risk of the film being carried away and out of the correct position due to the excessively fast movement speed of the manipulator. Finally, since the negative pressure-stabilized conveying assembly does not rely on the moving speed of the manipulator, the negative pressure-stabilized conveying assembly can be applied to more solar panel production scenarios with different specifications and types. This wide adaptability makes the solution have higher practical application value.

[0027] Among them: since the lower negative pressure hole with a larger diameter is subjected to a greater negative pressure, it can generate a stronger adsorption force. Therefore, when the second picking device picks up the glass, even if the glass moves upward and generates a certain force trying to drive the film, the larger lower negative pressure hole can provide sufficient negative pressure to offset this force, ensuring that the film will not be shifted as a result. The negative pressure distribution optimization caused by this diameter difference effectively realizes the balance of the three forces, thereby improving the stability of the film during the transportation process.

[0028] Among them: because the upper negative pressure hole and the lower negative pressure hole are both inclined, the inclined adsorption point can ensure that the force distribution of the film is more uniform under the action of negative pressure, thereby avoiding deformation or damage of the film caused by excessive local force.

[0029] Among them: because the upper negative pressure holes and the lower negative pressure holes are specially designed to adsorb the long sides of the film, and the long sides are closer to the center of mass, by setting negative pressure adsorption points at these two key positions, it can ensure that the film always remains flat during the transportation process, effectively reducing the risk of packaging failure and component scrapping due to deformation.

The outer surface of the second picking device 13 is rectangular and is fixedly connected to a plurality of trigger rods 39 that are arranged equidistantly.

[0049] The receiving seat 21 is installed on the external motor, and the external motor is electrically controlled to start and stop by the external controller. A pressure sensor is installed at the bottom of the first picking device 12, and the pressure sensor is electrically connected to the external controller. The piston block 28 is elliptical, and the smooth protrusion group 27 includes a plurality of protrusions. The diameter of the circle formed between every two protrusions is adapted to the diameter of the round rod group 23, and the edge between every two protrusions gradually expands outward, and the bottom of the airflow guide shell 29 gradually expands outward.

[0051] Two roller conveyors 14 are located in the middle of the storage rack 15, and the roller conveyors 14 are both electrically controlled to start and stop by an external controller. EVA films and glass are alternately placed on the top of the storage rack 15. The first picking device 12 and the second picking device 13 both include a slide plate and a lifting plate. The slide plate is slidably connected to the outer surface of the working frame 11, and the lifting plate is slidably connected to the inside of the slide plate. A driving cylinder 1 is installed on the outer surface of the working frame 11, and a driving cylinder 2 is installed on the outer surface of the slide plate. The output end of the driving cylinder 1 is fixedly connected to the outer surface of the slide plate, and the output end of the driving cylinder 2 is fixedly connected to the outer surface of the lifting plate. The first picking device 12 and the second picking device 13 are both electrically controlled to start and stop by an external controller.

[0052] The bottom of the first picking device 12 is linearly and equidistantly arranged symmetrically and fixedly connected with a plurality of suction cups, all of which are connected to an external negative pressure generator, and the external negative pressure generator is fixedly connected to the top of the lifting plate. The external negative pressure generator is electrically controlled to start and stop by an external controller, and a pressure sensor is installed at the bottom of the lifting plate, and the pressure sensor is electrically connected to the external controller.

[0053] Position sensors are installed at the bottom of the first picking device 12 and the second picking device 13. The position sensors are electrically connected to the external controller. The position sensors are arranged at a side of the bottom of the first picking device 12 away from the suction cup.

[0054] The first picking device 12 and the second picking device 13 are designed as mutually exclusive working modes, and the alternating switching of the working states is realized through the PLC program control, that is, when the first picking device 12 performs the EVA film picking operation under the control of the PLC, the second picking device 13 will be in a standby state and positioned above the roller conveyor 14, ready for the next round of glass picking tasks; conversely, when the second picking device 13 performs the glass picking task under the instruction of the PLC, the first picking device 12 will be located above the roller conveyor 14, ready for the next round of EVA film picking.

[0055] The working principle of the present invention is as follows: The following is the initial state: the torsion spring 210 is in a relaxed state, the blocking plate 211 blocks the airflow guide shell 29, the spring 34 is not compressed, and the sliding block 33 is located above the inner cavity 32.

[0056] The following are the specific steps of the work: Among them, the preparation work before conveying EVA film and glass: Figure 1 As shown, the operator needs to ensure that the EVA film and the glass are arranged alternately on the storage rack 15, and start the first picking device 12, the second picking device 13 and the roller conveyor 14 through an external controller.

[0057] Among them, the transportation of EVA film: Figures 2 to 6As shown, from the above steps, it can be known that the second picking device 13, the first picking device 12 and the roller conveyor 14 are all started by the external controller, and then under the control of the PLC program, the first picking device 12 and the second picking device 13 are operated, and the driving cylinder 1 of the first picking device 12 pushes the slide plate close to the storage rack 15, and at the same time drives the cylinder 2 to lower the lifting plate, so that the suction cup contacts the film, and when the suction cup contacts the film, the suction cup produces a slight deformation, and the suction cup with a slight deformation contacts the pressure sensor, so that the pressure sensor is triggered, and the pressure sensor sends an electrical signal to the external controller. At this time, the external controller electrically controls the external negative pressure generator and the external motor to start, and the external negative pressure generator generates negative pressure through the suction cup to firmly adsorb the film.

[0058] The first picking device 12 as a whole moves toward the approaching roller conveyor 14, and at the same time, the output shaft of the external motor drives the main shaft 22 inside the receiving seat 21 to rotate, and the main shaft 22 synchronously drives the round rod group 23 to rotate. Since the round rod group 23 is a round rod, and the smooth protrusion group 27 is composed of protrusions, the shape between each two protrusions is an arc design, and a meshing effect is formed between the two. Therefore, when the round rod group 23 rotates, the round rod group 23 pushes the smooth protrusion group 27 and the rectangular frame connecting rod 26 to reciprocate.

[0059] The movement of the rectangular frame connecting rod 26 will drive the piston block 28 to move synchronously. Since the piston block 28 is elliptical, the major axis and minor axis of the elliptical piston block 28 will produce different pressure changes during movement, thereby improving the efficiency of gas compression. The movement of the piston block 28 increases the compression rate of the gas in the gas cylinder 24, and causes one of the two gas cylinders 24 to start to take in air through the air hole 25, while the air inside the other gas cylinder 24 is compressed.

[0060] At the same time, the compressed air tries to escape from the air cylinder 24 and hits the torsion spring 210 and the sealing plate 211. When the air pressure is large enough, the elastic force of the sealing plate 211 cannot overcome the air pressure, and then the torsion spring 210 is tightened, the sealing plate 211 no longer blocks the airflow guide shell 29, and allows the compressed air to escape. The escaping compressed air moves along the gradually expanding inner wall trajectory of the airflow guide shell 29, and the airflow changes from a small angle to a large angle to form a fan-shaped airflow. The fan-shaped airflow acts on the top of the EVA film. Based on the Bernoulli principle, the edge of the EVA film is lifted by the airflow, and as the round rod group 23 continues to rotate, the two ends of the film are lifted alternately, thereby ensuring that the film remains flat during transportation and reduces deformation.

[0061] When the first picking device 12 reaches above the roller conveyor 14 and confirms its position through the position sensor, the external negative pressure generator is turned off and the EVA film is placed on the surface of the roller conveyor 14. At this time, the suction cup is reset, the pressure sensor is no longer triggered, the external motor is turned off, and a conveying cycle of the EVA film is completed.

[0062] The roller conveyor 14 continues to transport the EVA film to the next processing station.

[0063] Among them, the transportation of glass: Figures 7 to 10 As shown, after the first picking device 12 completes the conveying of the EVA film, the second picking device 13 starts to work according to the guidance of the PLC program, and the output end of the driving cylinder 1 located on one side of the second picking device 13 pushes the slide plate to slide along the working frame 11 toward the side close to the storage rack 15, and at the same time, the output end of the driving cylinder 2 drives the lifting plate to descend. As the lifting plate descends, the suction cup at its bottom contacts the glass surface and deforms, thereby triggering the pressure sensor at the bottom of the lifting plate. At this time, the pressure sensor sends an electrical signal to the external controller, and the external controller electrically controls the external negative pressure generator to start. At this time, the external negative pressure generator generates negative pressure, and firmly adsorbs the glass on the lifting plate through the suction cup, thereby ensuring the stability of the glass during subsequent movement.

[0064] During the descent of the lifting plate, the trigger rod 39 on the surface of the lifting plate contacts the sliding block 33 located inside the inner cavity 32 and pushes it down. At this time, the spring 34 is elastically compressed by the sliding block 33, and the descent of the sliding block 33 causes the air in the inner cavity 32 to be discharged through the pressure relief hole 35.

[0065] When the suction cup absorbs the glass, the lifting plate is driven to rise due to the contraction of the second output end of the driving cylinder, and the trigger rod 39 leaves the sliding block 33. At this time, the spring 34 causes the sliding block 33 to rise under the action of its own elastic force. Due to the increase in the internal space of the inner cavity 32, negative pressure is formed in the inner cavity 32. However, since the pressure relief hole 35 is connected to the outside, the negative pressure state in the inner cavity 32 can only exist temporarily.

[0066] At the same time, the negative pressure in the inner cavity 32 is transmitted to the upper negative pressure hole 37 and the lower negative pressure hole 38 through the negative pressure generating block 36. Since the upper negative pressure hole 37 and the lower negative pressure hole 38 are both inclined, and the diameter of the lower negative pressure hole 38 is larger than the upper negative pressure hole 37, under the action of negative pressure, the negative pressure generated by the upper negative pressure hole 37 and the lower negative pressure hole 38 can achieve a three-force balance.

[0067] Specifically, when the glass is lifted up by the suction cup, an adhesion force is generated between its bottom and the EVA film, and the lower negative pressure hole 38 with a larger diameter is subjected to a greater negative pressure, which can generate a stronger adsorption force. Therefore, when the second picking device 13 picks up the glass, even if the glass moves upward and generates a certain force trying to drive the film, the larger lower negative pressure hole 38 can provide sufficient negative pressure to offset this force, ensuring that the film will not shift as a result. Therefore, the adhesion force between the glass and the EVA film, the negative pressure of the upper negative pressure hole 37, and the negative pressure of the lower negative pressure hole 38 are balanced. At the same time, since the negative pressure state only exists for a short time, when the glass is detached from the EVA film, the negative pressure quickly adsorbs the film in place to prevent it from moving with the glass. At the same time, since the negative pressure acts on both sides of the EVA film, the EVA film will not shift during the separation process from the glass, thereby ensuring the accuracy and stability of the operation.

[0068] At this time, the second picking device 13 places the glass on the surface of the roller conveyor 14 close to the second picking device 13 according to the PLC program. At the same time, the external controller electrically controls the external negative pressure generator to turn off. At this time, the suction cup loses the negative pressure and places the glass steadily on the surface of the roller conveyor 14. The roller conveyor 14 will continue to transport the glass and transport it to the next workstation.
