Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic glass coating, and more specifically, to a double-sided coating device and method for photovoltaic glass. Background Art

[0002] Photovoltaic glass, as an important solar cell component material, is widely used in the field of solar power generation, especially in solar photovoltaic panels. It not only needs to have good light transmittance to ensure that sunlight can effectively penetrate and reach the solar cell, but also requires certain mechanical strength and weather resistance to adapt to the complex and changeable outdoor environmental conditions. In order to improve the photoelectric conversion efficiency and service life of photovoltaic glass, it is usually coated on its surface. Coating can not only improve the light transmittance of photovoltaic glass and reduce reflection loss, but also enhance its anti-fouling ability and corrosion resistance.

[0003] The existing coating of photovoltaic glass mainly includes melt-gel method, roller coating method, spraying method and the like. The existing photovoltaic glass spraying device needs to fix the photovoltaic glass on a fixing mechanism. Since the contact part between the fixing mechanism and the photovoltaic glass cannot be coated, in order to ensure the coating effect of the photovoltaic glass and the stability of the photovoltaic glass during coating, the double-sided coating of photovoltaic glass currently mostly uses a spraying mechanism to spray one side of the photovoltaic glass first, then takes out the photovoltaic glass and fixes the unsprayed side on the fixing mechanism facing the spraying mechanism, and then uses the spraying mechanism to spray the other side of the photovoltaic glass. This is time-consuming and labor-intensive, and the efficiency of double-sided spray coating is low. In view of this, we propose a double-sided coating device and method for photovoltaic glass.

[0015] A method for using a double-sided coating device for photovoltaic glass comprises the following steps:

[0016] S1: Adjust the position of the second fixed column;

[0017] The output shaft of motor B is controlled to rotate an integer number of circles by an external control mechanism, and the adjusting shaft drives the adjusting protrusion to rotate. When the adjusting protrusion is located in the arc space groove, the adjusting protrusion rotates to drive the adjusting block and the opposite screw rod to rotate, so that the second fixed column and the first fixed column form a symmetrical structure. At this time, the arc space groove and the annular space groove are still connected to form a rotating cavity.

[0018] S2: Fixing of photovoltaic glass;

[0019] The output shaft of motor A is controlled to rotate by an external control mechanism, so that the clamping cavities of the two clamping mechanisms are simultaneously enlarged, and the photovoltaic glass is placed on the carrier plate. The output shaft of motor A is controlled to rotate by an external control mechanism, so that the clamping cavities of the two clamping mechanisms are simultaneously reduced to clamp and fix the photovoltaic glass;

[0020] S3: Adjust the position of the second fixing column again;

[0021] The output shaft of the motor B is controlled to rotate by an external control mechanism so that the second fixed column is located in the sliding cavity;

[0022] S4: Double-sided coating of photovoltaic glass;

[0023] Two coating mechanisms are used to coat the photovoltaic glass on both sides. The output shaft of motor A is controlled to rotate by an external control mechanism, so that the sizes of the clamping cavities of the two clamping mechanisms are intermittently changed. There is always one clamping mechanism to clamp the photovoltaic glass, so that the photovoltaic glass does not need to be disassembled and reinstalled when double-sided coating is performed, thereby improving the efficiency of double-sided coating of the photovoltaic glass. When the movable shaft is at one end of the corresponding movable arc groove, the two clamping plates on the clamping mechanism clamp the photovoltaic glass. When the movable shaft moves to the other end of the corresponding movable arc groove, the two clamping plates on the clamping mechanism first move away from each other to enlarge the clamping cavity, and then move closer to each other to reduce the clamping cavity and clamp the photovoltaic glass again. The contact surface position between the clamping plate and the surface of the photovoltaic glass changes, and the clamping plate is separated from the original contact surface of the surface of the photovoltaic glass and moved to the position where the photovoltaic glass surface can be sprayed with coating, so that the clamping plate just covers the position where the photovoltaic glass surface is sprayed with coating, so that the surface of the photovoltaic glass is divided into several modules for alternating coating during coating, thereby improving the uniformity of double-sided coating of the photovoltaic glass and improving the effect of double-sided coating of the photovoltaic glass.

[0024] S5: Disassembly of photovoltaic glass;

[0025] After the double-sided coating of the photovoltaic glass is completed, the output shaft of motor B is controlled by an external control mechanism to rotate an integer number of circles, so that the second fixed column and the first fixed column form a symmetrical structure. The output shaft of motor A is controlled by an external control mechanism to rotate, so that the clamping cavities of the two clamping mechanisms become larger at the same time, and the photovoltaic glass is taken out.

[0026] The beneficial effects of the present invention are:

[0027] 1. The present invention arranges the structure of the fixed structure so that the two output ends of the rotating mechanism control the two rotating disks to rotate simultaneously, and the sizes of the clamping cavities of the two clamping mechanisms change simultaneously, which is used for the disassembly and fixation of the double-sided coating of the photovoltaic glass. The two output ends of the rotating mechanism control the two rotating disks to rotate intermittently, so that the sizes of the clamping cavities of the two clamping mechanisms change intermittently, and there is always a clamping mechanism to clamp the photovoltaic glass, so that the photovoltaic glass does not need to be disassembled and reinstalled when double-sided coating is performed, thereby improving the efficiency of double-sided coating of the photovoltaic glass. In the process of clamping, opening and re-clamping the two clamping plates on the clamping mechanism, the contact surface position of the clamping plate and the surface of the photovoltaic glass changes, so that the coating mechanism can spray the original clamping part of the photovoltaic glass, thereby improving the effect of double-sided coating of the photovoltaic glass.

[0028] 2. The present invention sets the gap distance between two clamping plates located in the same plane in the initial state, the width of the clamping plates and the gap length at both ends of the movable arc groove to be equal, so that when the movable axis moves from one end of the corresponding movable arc groove to the other end, the clamping plate is separated from the original contact surface with the photovoltaic glass surface, and moves to the position where the photovoltaic glass surface can be sprayed and coated, so that the clamping plate just covers the position where the photovoltaic glass surface was originally sprayed and coated, so that the photovoltaic glass surface is divided into several modules for alternating coating during coating, thereby improving the uniformity of double-sided coating of the photovoltaic glass and further improving the effect of double-sided coating of the photovoltaic glass.

[0029] 3. The present invention further designs the clamping plate so that when the movable shaft moves in the corresponding movable arc groove to change the position of the clamping plate, the telescopic rod retracts and drives the slider X to slide along the slide rail, so that the clamping plate cannot rotate, thereby preventing the clamping plate from scratching the surface of the photovoltaic glass when the photovoltaic glass is double-sided coated, thereby affecting the effect of the double-sided coating of the photovoltaic glass.

[0030] 4. The present invention uses the structural design of the rotating mechanism to achieve better synchronization in controlling the rotation of the two rotating disks, and the limiting effect of the limiting assembly can reduce the stability of the clamping mechanism in clamping the photovoltaic glass, without relying on motor A, thereby reducing the load of motor A and extending the use time.

[0054] like Figures 1 to 13As shown, the present invention relates to a double-sided coating device and method for photovoltaic glass, comprising a coating body 1, coating mechanisms 2 are provided on both sides of the coating cavity of the coating body 1, and a fixing structure 3 is provided in the gap between the two coating mechanisms 2;

[0055] The fixed structure 3 includes two mounting seats A4 and a mounting seat B5 arranged in an upper and lower structure, two clamping mechanisms 6 and a rotating mechanism 7; the mounting seat A4 and the mounting seat B5 are respectively fixedly connected to the two ends of the coating cavity of the coating machine body 1, and two groups of movable arc grooves 41 are opened at the proximal ends of the mounting seat A4 and the mounting seat B5, and each group of movable arc grooves 41 includes two arranged in a symmetrical structure, and the arc centers of the two movable arc grooves 41 coincide; the clamping mechanism 6 includes two clamping plates 61 and a rotating disk 65, and the two clamping plates 61 are staggered in an upper and lower structure, and the proximal ends of the two clamping plates 61 are fixed with friction pads 62, and the clamping plate 65 is fixed with a rotating disk 65. A swivel seat 63 is fixedly provided in the middle of both ends of the tightening plate 61, and a movable shaft 64 is rotatably connected to the swivel seat 63. The movable shaft 64 is movably connected to the corresponding movable arc groove 41. The rotating disk 65 is arranged in the mounting seat B5, and the rotating disk 65 is rotatably connected to the mounting seat B5 through the rotating shaft A66. The rotating shaft A66 coincides with the arc center of the corresponding movable arc groove 41. The two movable shafts 64 located below are both inserted into the mounting seat B5 and are rotatably connected to the rotating disk 65; the rotating mechanism 7 is arranged in the swivel seat 63 located below, and the rotating mechanism 7 has two rotating ends, and the two rotating ends are respectively fixedly connected to the two rotating disks 65. The present invention arranges the structure of the fixed structure 3 so that when the two output ends of the rotating mechanism 7 control the two rotating disks 65 to rotate simultaneously, the movable shaft 64 moves in the corresponding movable arc groove 41, so that the position of the clamping plate 61 changes, so that the size of the clamping cavity formed by the corresponding two clamping plates 61 changes simultaneously, which is used for the disassembly and fixation of the double-sided coating of the photovoltaic glass. The two output ends of the rotating mechanism 7 control the two rotating disks 65 to rotate intermittently, so that the size of the clamping cavity of the two clamping mechanisms 6 changes intermittently, and there is always a clamping mechanism 6 to clamp the photovoltaic glass, so that the photovoltaic glass does not need to be disassembled and reinstalled when double-sided coating is performed, thereby improving the efficiency of double-sided coating of the photovoltaic glass, and the movable shaft 64 moves in the corresponding movable arc groove 41. When the movable shaft 64 moves to one end of the movable arc groove 41, the two clamping plates 61 on the clamping mechanism 6 clamp the photovoltaic glass. When the movable shaft 64 moves to the other end of the corresponding movable arc groove 41, the two clamping plates 61 on the clamping mechanism 6 first move relatively far away to make the clamping cavity larger, and then move relatively close to make the clamping cavity smaller to re-clamp the photovoltaic glass. The contact surface position between the clamping plate 61 and the surface of the photovoltaic glass changes, so that the coating mechanism 2 can spray the original clamping part of the photovoltaic glass, thereby improving the double-sided coating effect of the photovoltaic glass. Among them, the friction pad 62 is provided to increase the friction between the clamping plate 61 and the surface of the photovoltaic glass, and reduce the damage that may be caused by the clamping plate 61 in the process of clamping the photovoltaic glass.

[0056] In the embodiment of the present invention, the gap distance between the two clamping plates 61 located in the same plane in the initial state, the width of the clamping plates 61 and the gap length at both ends of the active arc groove 41 are equal. Through the above arrangement, the present invention allows the clamping plate 61 to separate from the original contact surface of the photovoltaic glass surface when the active shaft 64 moves from one end of the corresponding active arc groove 41 to the other end, and move to the position where the photovoltaic glass surface can be sprayed and coated, and the width of the clamping plate 61 and the gap length at both ends of the active arc groove 41 are equal, so that the clamping plate 61 just covers the position where the photovoltaic glass surface was originally sprayed and coated, so that the photovoltaic glass surface is divided into several modules for alternating coating during coating, which improves the uniformity of double-sided coating of the photovoltaic glass and further improves the effect of double-sided coating of the photovoltaic glass.

[0057] In an embodiment of the present invention, a supporting plate 51 is fixedly provided in the middle of the top of the mounting seat B5, a mounting cavity A52 is opened in the mounting seat B5 and is connected to the four movable arc grooves 41 located below, a rotating disk 65 is arranged in the mounting cavity A52, a mounting cavity B50 is provided below the mounting cavity A52, a mounting cavity C53 is opened in the mounting cavity A52, and slide rails 54 are fixedly provided at both ends of the mounting seat A4 and the mounting seat B5.

[0058] In the embodiment of the present invention, at least one telescopic rod 67 is fixedly provided at both ends of the clamping plate 61, and a slider X68 is fixedly provided at one end of the telescopic rod 67 away from the clamping plate 61, and the slider X68 is slidably connected with the corresponding slide rail 54. The present invention further designs the clamping plate 61, so that when the movable shaft 64 moves in the corresponding movable arc groove 41 to change the position of the clamping plate 61, the telescopic rod 67 is extended and retracted and drives the slider X68 to slide along the slide rail 54, so that the clamping plate 61 cannot rotate, so as to prevent the clamping plate 61 from scratching the surface of the photovoltaic glass when the photovoltaic glass is double-sided coated, thereby affecting the effect of the double-sided coating of the photovoltaic glass.

[0059] In an embodiment of the present invention, the rotating mechanism 7 includes an adjusting component 70, a motor A71, a rotating shaft B72, and two rotating shafts C77.

A driving disk 73 is fixedly arranged at the top of the rotating shaft B72. A limiting component 74 is fixedly arranged at the center position of the top of the driving disk 73.

Through the above-mentioned arrangement, the present invention can control the rotation of the output shaft of the motor A71 through an external control mechanism, so that the rotating shaft B72 can drive the driving disk 73 to rotate, and the first fixed column 75 rotates accordingly. When the first fixed column 75 moves in the centripetal guide groove 79, it will drive the connecting disk 78 to rotate, thereby causing the rotating disk 65 to rotate. The rotation of the rotating disk 65 during the process from the first fixed column 75 entering the centripetal guide groove 79 to the process of disengaging from the centripetal guide groove 79 can just enable the rotating disk 65 to drive the movable shaft 64 to move from one end of the corresponding movable arc groove 41 to the other end.

[0060] In an embodiment of the present invention, a slide groove A731 is provided at the top of the driving disk 73, a movable cavity 732 is provided on the slide groove A731, slide grooves B733 are provided at both ends of the movable cavity 732, an annular groove 734 is provided on the surface of the driving disk 73, and a rotating groove 735 is provided on the annular groove 734.

[0061] In the embodiment of the present invention, the limiting assembly 74 includes a limiting disc 741, and the limiting disc 741 is symmetrically provided with two arc notches 742, one of which coincides with the axis of the first fixing column 75, and a missing block 743 is provided on the arc notch 742 away from the first fixing column 75, and the missing block 743 is adapted to the shape of the limiting disc 741, and the limiting disc 741 and the missing block 743 are both movably matched with the limiting arc groove 710, and the limiting disc 7 41 and the bottom end of the missing block 743 are both provided with a sliding cavity 744 relative to the slide groove A731, the movable cavity 732 is adapted to the shape of the missing block 743, the missing block 743 is movably connected with the movable cavity 732, the missing block 743 is slidably connected with the slide groove B733 through a slider B745, circular grooves 746 are both provided at both ends of the missing block 743, the circular groove 746 and the movable cavity 732 are elastically connected through a spring 747, wherein the trapezoidal guide block 763 is movably matched with the missing block 743.

[0062] In an embodiment of the present invention, the movable column assembly 76 includes an opposing screw rod 761 and an adjusting block 765. The opposing screw rod 761 is rotatably arranged on the slide groove A731. Both ends of the opposing screw rod 761 are threadedly connected with sliders A762. The slider A762 is slidably connected to the slide groove A731. A trapezoidal guide block 763 is fixed to the top of the slider A762 close to the first fixed column 75, and a second fixed column 764 is fixed to the top of the slider A762 away from the first fixed column 75. The adjusting block 765 is rotatably arranged on the rotating groove 735. An arc space groove 766 is opened on the adjusting block 765. The arc space groove 766 is connected with the annular space groove 734 to form a rotating cavity. The end of the opposing screw rod 761 close to the adjusting block 765 penetrates into the rotating groove 735 and is fixedly connected to the adjusting block 765. It is worth mentioning that the two thread grooves on the opposing screw rod 761 are not the same, and the stepping distance of the thread groove on the side close to the trapezoidal guide block 763 is smaller than the stepping distance of the thread groove on the side away from the trapezoidal guide block 763. Through the above arrangement, the present invention enables the two sliders A762 to move in opposite directions in the slide groove A731 when the opposing screw rod 761 rotates, so that the second fixed column 764 and the trapezoidal guide block 763 move in opposite directions, wherein, as Fig. 9 As shown, when the second fixed column 764 and the trapezoidal guide block 763 are relatively close to each other and move, the inclined surface of the trapezoidal guide block 763 contacts the missing block 743 first, so that the missing block 743 moves upward in the movable cavity 732, and the slider B745 slides upward in the slide groove B733 until the second fixed column 764 is released from the movable cavity 732. Figure 8 The status shown is active until Figure 7 It is worth noting that when in the state Figure 7When the second fixing post 764 is in the sliding cavity 744, the driving disc 73 rotates to drive the first fixing post 75 to rotate, and the first fixing post 75 first enters the centripetal guide groove 79 on one of the connecting discs 78 to move, so that the connecting disc 78 rotates, and the arc notch 742 provides a gap for the rotation of the connecting disc 78. When the first fixing post 75 is disengaged from the centripetal guide groove 79, during this process, the surface of the limiting unit formed by the limiting disc 741 and the missing block 743 contacts and limits the upper limiting arc groove 710 of the other connecting disc 78, and then the first fixing post 75 first enters the centripetal guide groove 79 on the other connecting disc 78 to move and cause the connecting disc 78 to rotate. Figure 8 In the state shown, the second fixed column 764 and the first fixed column 75 form a symmetrical structure, and the rotation of the driving disk 73 drives the second fixed column 764 and the first fixed column 75 to rotate simultaneously.

Through the above arrangement, the present invention enables the output shaft of the motor B701 to rotate by controlling the rotation of the adjustment shaft 702 through an external control mechanism, and the adjustment shaft 702 drives the adjustment protrusion 703 to rotate.

At this time, the arc space groove 766 and the annular space groove 734 are still connected to form a rotating cavity.

[0067] S2: Fixing of photovoltaic glass;

[0068] The output shaft of the motor A71 is controlled to rotate by an external control mechanism, so that the clamping cavities of the two clamping mechanisms 6 are simultaneously enlarged, and the photovoltaic glass is placed on the carrier plate 51. The output shaft of the motor A71 is controlled to rotate by an external control mechanism, so that the clamping cavities of the two clamping mechanisms 6 are simultaneously reduced to clamp and fix the photovoltaic glass;

The contact surface position between the clamping plate 61 and the photovoltaic glass surface is changed. The clamping plate 61 is separated from the original contact surface with the photovoltaic glass surface and moved to the position where the photovoltaic glass surface was originally sprayed with coating, so that the clamping plate 61 just covers the position where the photovoltaic glass surface was originally sprayed with coating, so that the photovoltaic glass surface is divided into several modules for alternating coating during coating, thereby improving the uniformity of double-sided coating of the photovoltaic glass and improving the effect of double-sided coating of the photovoltaic glass.

[0073] S5: Disassembly of photovoltaic glass;

[0074] After the double-sided coating of the photovoltaic glass is completed, the output shaft of the motor B701 is controlled by an external control mechanism to rotate an integer number of circles, so that the second fixed column 764 and the first fixed column 75 form a symmetrical structure. The output shaft of the motor A71 is controlled by an external control mechanism to rotate, so that the clamping cavities of the two clamping mechanisms 6 become larger at the same time, and the photovoltaic glass is taken out.
