Description

Technical Field

[0001] The present invention relates to the technical field of glass loading and unloading, and more specifically, to automatic loading and unloading equipment for photovoltaic glass. Background Art

[0002] Photovoltaic glass is mainly composed of glass, solar cells, film, back glass and special metal wires. These components work together to enable photovoltaic glass to effectively use solar radiation to generate electricity. Since photovoltaic glass is easy to break during transportation, it is generally stacked and bundled for easy transportation.

[0003] In the actual loading and unloading process of photovoltaic glass, suction cranes are mostly used for loading and unloading. After the photovoltaic glass is transported to the designated location by the conveyor, it is transferred by the suction crane. When the photovoltaic glass is transported to the designated location, the conveyor stops immediately, and the photovoltaic glass is displaced in the direction of movement due to inertia. When the photovoltaic glass is heavy, it is easy for the glass to fall or the side to be damaged. In addition, when the photovoltaic glass is transported, its side contacts the conveyor, which makes it easy for impurities and dust to be adsorbed on its side. When it cannot be transported, the side of the photovoltaic glass can be cleaned synchronously.

[0004] When the glass is stacked and loaded by a suction crane, it is affected by the lifting posture, lifting speed and suction cup selection, and it is impossible to ensure that the sides of the photovoltaic glass are stacked neatly every time, which in turn affects the stability of the stacking;

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1-Figure 8 As shown, when the suction lifting machine in the prior art stacks and loads the glass, it is affected by the lifting posture, lifting speed and suction cup selection, etc., and it is impossible to ensure that the sides of the photovoltaic glass are stacked neatly every time, which affects the stacking stability of the glass plates. The following solution can be used to solve the problem;

[0033] In this embodiment, an automatic loading and unloading device for photovoltaic glass includes two sets of connecting frames 1, the connecting frames 1 are connected to a warehouse or a mobile device, the two sets of connecting frames 1 are fixedly connected by a limit plate 3, and a motor 1 is fixedly arranged on the side wall of one connecting frame 1, a threaded rod 2 is fixedly connected to the output end of the motor 1, the end of the threaded rod 2 is rotatably connected to the other connecting frame 1 through a bearing, and a movable seat 6 is commonly arranged on the outer wall of the threaded rod 2 and the limit plate 3;

[0034] Then, the threaded rod 2 is driven to rotate by controlling the motor 1, so that the moving seat 6 on the threaded rod 2 is limited by the limiting plate 3 to move horizontally back and forth;

[0035] A reduction motor 7 is provided at the bottom of the moving seat 6, a cylinder 10 is provided at the output end of the reduction motor 7, a mounting frame 8 is provided at the output end of the cylinder 10, a suction and lifting tool 9 is provided at the bottom of the mounting frame 8, and a stacking regulating component 5 for adjusting the side of the stacked glass is provided on the outer side of the suction and lifting tool 9;

[0036] It should be noted that the suction and lifting tool 9 is a device in the prior art that has the function of adsorbing and transporting photovoltaic glass. It is a prior art and will not be described in detail here. It is only necessary to have the adsorption and transport function for the photovoltaic glass.

[0037] When the moving seat 6 moves to the loading position, the extended end of the control cylinder 10 extends downward to the preparation position, and the suction and lifting tooling 9 is moved above the photovoltaic glass without contacting the upper surface of the photovoltaic glass. At this time, the photovoltaic glass transported by the conveyor is intercepted by the push plate 511 on one side to prevent it from falling or being damaged due to inertia.

[0038] The extended end of the control cylinder 10 extends downward to the adsorption position. After the photovoltaic glass is adsorbed by the suction and lifting fixture 9, the extended end of the control cylinder 10 is retracted to the preparation position. The motor 1 is controlled again to drive the threaded rod 2 to rotate, and the suction and lifting fixture 9 is moved to the unloading device through the moving seat 6.

[0039] The stacking regulating assembly 5 includes three side plates 53 fixedly arranged on the outer wall of the cylinder 10, an upper regulating box 54 is vertically inserted on the outer wall of the side plate 53, three fixed plates 51 are arranged on the outer wall of the mounting frame 8, and the side plates 53 correspond to the fixed plates 51, a piston plate 55 is slidably arranged inside the upper regulating box 54, a piston rod 56 is fixedly arranged at the bottom of the piston plate 55, the bottom end of the piston rod 56 is movably penetrated to the outside of the regulating box and connected to the fixed plate 51 below it, and a thrust spring 1 is sleeved on the outer wall of the piston rod 56 located below the piston plate 55;

[0040] Before the photovoltaic glass reaches the unloading position: control the reduction motor 7 to drive the suction and lifting tooling 9 to rotate, and make the side without the lower control box 58 correspond to the unloading position, because there is a shielding object on one side as support at the unloading position of the photovoltaic glass, which is convenient for stacking the photovoltaic glass;

[0041] It should be supplemented here that: a balance hole is opened on the top wall of the upper control box 54, and a control valve is arranged inside the balance hole. When the cylinder 10 is in the ready position, the control valve is closed. When the cylinder 10 moves downward from the ready position, the control valve is opened to maintain the air pressure inside the upper control box 54 stable. When the cylinder 10 moves upward from the ready position, the control valve is closed.

[0042] A telescopic plate 52 is slidably provided inside the fixed plate 51, and the fixed plate 51 and the telescopic plate 52 are fixedly connected by bolts. A lower regulating box 58 is fixedly provided at the end of the telescopic plate 52, and a piston plate 59 is slidably provided inside the lower regulating box 58. A piston rod 510 is fixedly provided on the side wall of the piston plate 59. The end of the piston rod 510 is movable and penetrates to the outside of the lower regulating box 58 and is fixedly provided with a push plate 511. A thrust spring 2 is sleeved on the outer wall of the piston rod 510, and a rubber pad is provided on the side wall of the push plate 511. The upper regulating box 54 and the lower regulating box 58 are connected through a connecting pipe 57.

[0043] After reaching the unloading position, the extended end of the cylinder 10 is controlled to move downward, and the adsorbed photovoltaic glass is stacked on the photovoltaic glass below. At this time, the extended end of the cylinder 10 contracts upward, first to the preparation position and then to the regulating position, and the piston plate 1 55 moves upward to squeeze the gas inside the upper regulating box 54 into the lower regulating box 58 through the connecting pipe 57. The air pressure inside the lower regulating box 58 increases, and the piston plate 2 59 is squeezed to one side, and the push plate 511 is pushed to one side. The three groups of push plates 511 push the photovoltaic glass synchronously, thereby adjusting the stacking side position of the photovoltaic glass to ensure its stacking stability;

[0044] It should be additionally explained here that the connecting pipe 57 has elasticity.

[0045] Example 2: Please refer to Figure 1-Figure 3 , Figure 7-Figure 8 As shown, when the photovoltaic glass is being transported, its side is in contact with the conveyor, and is easily adsorbed with impurities and dust, and the side of the photovoltaic glass cannot be cleaned synchronously during its transportation. This problem can be solved by the following solution;

[0046] In this embodiment, a side cleaning assembly 4 for cleaning and removing impurities from the sides of the photovoltaic glass is arranged on the outside of the suction and lifting tooling 9. The side cleaning assembly 4 includes a toothed plate 41 fixedly arranged between the two connecting frames 1. A driving shaft is rotatably arranged on the top of the movable seat 6. A gear 42 is fixedly arranged on the outer wall of the driving shaft. The gear 42 is meshed and connected with the toothed plate 41. A fan member 43 is fixedly arranged at the end of the driving shaft. A conveying pipe 44 is arranged at the output end of the fan member 43. A side cleaning pipe 45 is connected to the output end of the conveying pipe 44. The side cleaning pipe 45 is provided with four side blowing pipes, and the side blowing pipes are arranged toward the sides of the photovoltaic glass.

[0047] In the process of transporting the photovoltaic glass, the gear 42 is meshed with the tooth plate 41, and the driving shaft at the center of the gear 42 rotates, thereby driving the fan to rotate, so that the gas is transported to the inside of the side cleaning pipe 45 through the delivery pipe 44, and the sides of the photovoltaic glass are continuously blown through the four side blowing pipes to clean the impurities and dust on the sides, thereby improving the stacking quality of the photovoltaic glass;

[0048] It should be explained that the fan member 43 includes a protective cover and a fan, and the fan is connected to the drive shaft. The protective cover is arranged on the outside of the fan and is rotatably connected to the outer wall of the drive shaft through a bearing.

[0049] In the present invention, it can be seen from the combination of Example 1 and Example 2 that:

[0050] Before transporting the photovoltaic glass, the photovoltaic glass output by the conveyor is intercepted by the push plate 511 to prevent it from being damaged; during the transportation of the photovoltaic glass, the gear 42 is meshed with the tooth plate 41, and the drive shaft at the center of the gear 42 rotates, thereby driving the fan to rotate, so that the gas is transported to the inside of the side cleaning pipe 45 through the delivery pipe 44, and the side of the photovoltaic glass is continuously blown through the four side blowing pipes to clean the impurities and dust on the side;

[0051] After the photovoltaic glass is transported, the gas inside the upper regulating box 54 is squeezed to the inside of the lower regulating box 58 through the connecting pipe 57 through the contraction of the cylinder 10. The air pressure inside the lower regulating box 58 increases, squeezing the piston plate 2 59 to one side, and pushing the push plate 511 to one side. The three groups of push plates 511 push the photovoltaic glass synchronously, and then adjust the stacking side position of the photovoltaic glass. The present invention starts from the three angles of before, during and after the transportation of the photovoltaic glass, which not only avoids damage to the photovoltaic glass during loading and unloading, cleans impurities on the side of the photovoltaic glass, improves the quality of the glass during loading and unloading, but also improves the stability and flatness of the stacked glass.

[0052] Working principle:

[0053] Step 1: Control motor 1 to drive threaded rod 2 to rotate, so that the movable seat 6 on threaded rod 2 is limited by the limit plate 3 to move horizontally back and forth. When the movable seat 6 moves to the loading position, the extended end of the control cylinder 10 extends downward to the preparation position, and the suction and lifting tooling 9 is moved to the top of the photovoltaic glass without contacting the upper surface of the photovoltaic glass. At this time, the photovoltaic glass transported by the conveyor is intercepted by the push plate 511 on one side to prevent it from falling or being damaged due to inertia.

[0054] Step 2: Control the extended end of the cylinder 10 to extend downward to the adsorption position. After the photovoltaic glass is adsorbed by the suction and lifting fixture 9, control the extended end of the cylinder 10 to retract to the ready position, control the motor 1 again to drive the threaded rod 2 to rotate, and move the suction and lifting fixture 9 to the unloading device through the moving seat 6:

[0055] Before reaching the unloading position: control the reduction motor 7 to drive the suction and lifting tooling 9 to rotate, and make the side without the lower control box 58 correspond to the unloading position;

[0056] After reaching the unloading position: the extended end of the cylinder 10 is controlled to move downward, and the adsorbed photovoltaic glass is stacked on the photovoltaic glass below. At this time, the extended end of the cylinder 10 is retracted upward, first to the preparation position and then to the regulating position, and the piston plate 1 55 moves upward to squeeze the gas inside the upper regulating box 54 into the lower regulating box 58 through the connecting pipe 57. The air pressure inside the lower regulating box 58 increases, and the piston plate 2 59 is squeezed to one side, and the push plate 511 is pushed to one side. The three groups of push plates 511 push the photovoltaic glass synchronously, thereby adjusting the stacking side position of the photovoltaic glass to ensure its stacking stability;

[0057] In this step, the gear 42 is meshed with the tooth plate 41, and the driving shaft at the center of the gear 42 rotates, thereby driving the fan to rotate, so that the gas is transported to the inside of the side cleaning tube 45 through the delivery pipe 44, and the sides of the photovoltaic glass are continuously blown through four side blowing pipes to clean the impurities and dust on the sides, thereby improving the stacking quality of the photovoltaic glass.
