Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic assembly installation, and in particular to a photovoltaic panel auxiliary installation robot. Background Art

[0002] Since a photovoltaic module weighs more than 20 kg, and the photovoltaic bracket is generally designed to place 4 photovoltaic modules vertically, the highest module is installed at a height of about 2.5 meters from the ground, which means that it takes 5 to 6 people to install the highest module, and the installation efficiency of photovoltaic modules is low, the workload of workers is large, and there are also some safety hazards. In addition, when installing photovoltaic modules that are higher than the photovoltaic bracket, workers need to step on the surface of the installed modules to transport the modules, which is easy to cause hidden cracks inside the installed photovoltaic modules, affecting the power generation of the photovoltaic modules in the future, resulting in a decrease in the efficiency of the photovoltaic power station.

[0003] Chinese patent announcement No. CN209256233U discloses a photovoltaic component auxiliary installation device, which is characterized in that it includes a walking mechanism, a conveying mechanism and a blanking mechanism; wherein the walking mechanism is erected on the inclined surface of the photovoltaic bracket and can move horizontally on the photovoltaic bracket; the conveying mechanism is relatively fixed to the walking mechanism, and is used to transfer the photovoltaic components from the bottom end to the top end of the photovoltaic bracket; the blanking mechanism is arranged on the walking mechanism and can move horizontally relative to the walking mechanism, and is used to grab the photovoltaic components on the conveying mechanism and drop them onto the photovoltaic bracket.

[0004] The above scheme provides an auxiliary installation device for placing the photovoltaic panel on the bracket, but lacks a mechanism for fixing the photovoltaic panel placed on the bracket. When installing the existing photovoltaic panel, it is necessary to first place the photovoltaic panel on the bracket, and then fix the photovoltaic panel from the bottom of the photovoltaic panel. This is because the fixing holes reserved on the photovoltaic panel are located at the bottom of the photovoltaic panel. Although there is an auxiliary device that can place the photovoltaic panel on the bracket, it cannot fix the photovoltaic panel. In the subsequent process of fixing the photovoltaic panel, it still needs to be done manually. If the photovoltaic panel is covered with the bracket by the auxiliary device, the surrounding light is easily blocked by the photovoltaic panel when the subsequent staff installs the bracket, and the staff is laborious to move in the bracket, and the labor intensity is relatively high. Summary of the invention

[0005] In view of the above problems, a photovoltaic panel auxiliary installation robot is provided. The present invention sets an extension arm at the lower part of the laying unit so that one end of the extension arm rotates with the laying unit. The extension arm has a working state and an avoidance state during the rotation process. The two states of the extension arm are adjusted by a reset unit so that when the extension arm moves with the laying unit, the extension arm is in a working state when it is not in contact with the vertical pole, and in an avoidance state when the extension arm is in contact with the vertical pole. After the extension arm completely passes through the vertical pole, the reset unit drives the extension arm to rotate from the avoidance state to the working state. In the working state, the electric screwdriver on the extension arm coincides with the through groove on the bracket and the installation hole on the photovoltaic panel. In summary, the present invention reduces the workload of the staff and improves the installation efficiency of the photovoltaic panels.

[0006] To solve the problems of the prior art, the present invention provides a photovoltaic panel auxiliary installation robot, including a laying unit for laying the photovoltaic panel on a bracket, the bracket including a plurality of vertical rods arranged in a horizontal direction, and a mounting hole is provided at the lower portion of the photovoltaic panel; a fixing unit for fixing the lower portion of the photovoltaic panel is provided below the laying unit, the fixing unit including an extension arm rotatably arranged at one end at the lower portion of the laying unit, the end of the extension arm rotatably connected to the laying unit is called a rotating end, the end of the extension arm rotating around the rotating end is called a planetary end, an electric screwdriver is provided on the planetary end, and the extension arm has a working state and an avoidance state when rotating on the laying unit, when the laying unit moves along the length direction of the bracket, the extension arm moves synchronously with the laying unit and switches to the avoidance state when contacting the vertical rod, when the extension arm completely passes through the vertical rod, the extension arm switches to the working state, and at this time the electric screwdriver on the extension arm is aligned with the mounting hole at the lower portion of the photovoltaic panel, and a reset unit for switching the extension arm from the avoidance state to the working state is provided on the rotating end of the extension arm.

[0007] Preferably, the resetting unit comprises a first rotation driver capable of driving the extension arm to rotate.

[0008] Preferably, a rotating sleeve is fixedly provided on the rotating end of the extension arm, a plurality of one-way teeth are fixedly provided on the inner wall of the rotating sleeve around the axis of the rotating sleeve, a rotating column is fixedly provided on the output end of the first rotary driver, the rotating column extends into the rotating sleeve, a spring sheet is fixedly and obliquely provided on the side wall of the rotating column, the spring sheet is unidirectionally meshed with the one-way teeth, and the elastic force when the spring sheet bends over the one-way teeth is greater than the total weight of the extension arm on which the electric screwdriver is provided.

[0009] Preferably, when the extension arm is rotated to a horizontal state, the force exerted by the weight of the electric screwdriver on the extension arm is the greatest, and the elastic force exerted by the spring sheet when it bends over the one-way tooth is greater than the force.

[0010] Preferably, a torsion spring box is further provided on the rotating end of the extension arm, and the torsion spring box and the rotating sleeve are respectively provided on the lower part and the upper part of the extension arm.

[0011] Preferably, a limit block is provided at one end of the extension arm, and when the extension arm rotates to a working state, it contacts the limit block and stops rotating.

[0012] Preferably, a driving trolley for driving the laying unit to move along the length direction of the bracket is provided on one side of the laying unit.

[0013] Preferably, a lifting sleeve is vertically arranged above the driving trolley, and a lifting rod is slidably arranged in the lifting sleeve along the extension direction of the lifting sleeve. The lifting rod extends from the upper part of the lifting sleeve, and an air pump and a switch valve are arranged on the side wall of the lifting sleeve, and the air pump and the switch valve are both connected to the lifting sleeve.

[0014] Preferably, a support frame for supporting the laying unit is hinged at the upper part of the lifting rod, a slide is fixedly arranged on the support frame along the width direction of the support frame, the laying unit is movably arranged on the slide along the extension direction of the slide, and a second rotary drive for driving the support frame to rotate is arranged at the lower part of the support frame.

[0015] Preferably, the laying unit comprises a plurality of rollers, and the rollers are in rolling cooperation with the highest position of the upper end surface of the bracket along the length direction of the bracket.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets an extension arm at the lower part of the laying unit so that one end of the extension arm rotates with the laying unit. The extension arm has a working state and an avoidance state during the rotation process, and the two states of the extension arm are adjusted by a reset unit, so that when the extension arm moves with the laying unit, the extension arm is in a working state when it is not in contact with the vertical pole, and in an avoidance state when the extension arm is in contact with the vertical pole. After the extension arm completely passes through the vertical pole, the reset unit drives the extension arm to rotate from the avoidance state to the working state. In the working state, the electric screwdriver on the extension arm coincides with the through groove on the bracket and the installation hole on the photovoltaic panel. In summary, the present invention reduces the workload of the staff and improves the installation efficiency of the photovoltaic panel.

[0017] 2. The torsion spring in the torsion spring box provides torque to the extension arm, so that the load of the first rotary driver is reduced in the process of driving the extension arm from the avoidance state to the working state. At the same time, as the extension arm equipped with the electric screwdriver rotates from the working state to the avoidance state, the downward rotation force applied by the electric screwdriver to the extension arm gradually increases. This is because the extension arm gradually tends to a horizontal state during the rotation process, and the force exerted by the weight of the electric screwdriver on the planetary end of the extension arm gradually increases. In order to avoid the situation where the extension arm continues to rotate after passing the vertical rod because the elastic force of the spring piece is less than the force exerted by the electric screwdriver on the planetary end of the extension arm, the winding spring box arranged at the rotating end of the extension arm can also reduce the load of the spring piece, thereby extending the service life of the spring piece.

[0018] 3. By setting the lifting rod and lifting sleeve, when the laying unit is placed on the bracket, the switch valve is opened, and the lifting rod and the lifting sleeve slide freely in the vertical direction. When the driving trolley bumps in the vertical direction during movement, the lifting rod and the lifting sleeve slide relative to each other, and the driving trolley can still drive the laying unit through the lifting rod and the lifting sleeve.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figure 1-Figure 3 A photovoltaic panel auxiliary installation robot includes a laying unit 2 for laying a photovoltaic panel 11 on a bracket 1, the bracket 1 includes a plurality of vertical rods 12 arranged in a horizontal direction, and a mounting hole 111 is provided at the lower part of the photovoltaic panel 11; a fixing unit 3 for fixing the lower part of the photovoltaic panel 11 is provided below the laying unit 2, and the fixing unit 3 includes an extension arm 31 rotatably arranged at one end at the lower part of the laying unit 2, and the end of the extension arm 31 rotatably connected to the laying unit 2 is called a rotating end, and the end of the extension arm 31 rotating around the rotating end is called a planetary end, and a planetary end is provided on the planetary end. There is an electric screwdriver 32, and the extension arm 31 has a working state and an avoidance state when it rotates on the laying unit 2. When the laying unit 2 moves along the length direction of the bracket 1, the extension arm 31 moves synchronously with the laying unit 2 and switches to the avoidance state when it contacts the vertical rod 12. When the extension arm 31 completely passes through the vertical rod 12, the extension arm 31 switches to the working state, and at this time the electric screwdriver 32 on the extension arm 31 is aligned with the mounting hole 111 at the lower part of the photovoltaic panel 11, and a reset unit 33 is provided on the rotating end of the extension arm 31 to switch the extension arm 31 from the avoidance state to the working state.

[0034] In the process of laying photovoltaics over a large area, the bracket 1 is usually arranged in a row. When installing the photovoltaic panel 11, two to three photovoltaic panels 11 are arranged on the inclined surface of the upper part of the bracket 1 along the inclined direction of the upper end face of the bracket 1 according to the size of the bracket 1. The bracket 1 used in the present invention can only install two photovoltaic panels 11 in the inclined direction of the upper end face of the bracket 1. In order to ensure the support of the bracket 1, the bracket 1 is provided with a vertical rod 12 for providing support in the vertical direction, and the bracket 1 also includes a horizontal cross bar 13. The cross bar 13 has two functions. One is to improve the supporting strength of the bracket 1, and the other is to facilitate the installation personnel to stand on the cross bar 13 to install the photovoltaic panel 11. However, since a plurality of cross bars 13 and vertical rods 12 are provided in the bracket 1, in the traditional installation operation, the staff needs to drill into the bracket 1 and step on the cross bar 13 to fix the photovoltaic panel 11 placed on the bracket 1 during the installation. Since the staff is always in a state of looking up when fixing the photovoltaic panel 11, the long-term operation puts a lot of pressure on the staff's neck, and the vertical rods 12 and cross bars 13 distributed in the bracket 1 also hinder the staff's operation, and the operation intensity is relatively large. At the same time, in the existing installation process, the photovoltaic panel 1 The process of placing the photovoltaic panel 11 on the bracket 1 also requires the operation of the staff. In order to reduce the workload of the staff, although a laying unit 2 that can automatically lay the photovoltaic panel 11 on the bracket 1 is provided in the prior art, the photovoltaic panel 11 still needs to be fixed after laying, and the fixing process still requires manual operation by the staff, and because the laying unit 2 is fast in the automatic laying process, the staff cannot keep up with the laying speed of the laying unit 2 when fixing the photovoltaic panel 11. If the laying unit 2 lays the photovoltaic panel 11 first, and the staff fixes the photovoltaic panel 11, in the process of fixing the photovoltaic panel 11, it is easy for the staff to accidentally push the adjacent photovoltaic panel 11, thereby causing the mounting hole 111 on the photovoltaic panel 11 to be offset, and the position of the photovoltaic panel 11 needs to be manually adjusted in the subsequent installation process.

[0035] In order to avoid the above situation, a fixing unit 3 is added to the existing laying unit 2, so that the fixing unit 3 can not only automatically fix the photovoltaic panel 11 as the laying unit 2 is laid, but also avoid the vertical rod 12, thereby avoiding the fixing unit 3 being blocked by the vertical rod 12 when moving with the laying unit 2. The specific structure and working process of the fixing unit 3 are as follows: The electric screwdriver 32 in the present invention is an automatic screw-feeding electric screwdriver 32. Two fixing units 3 in the present invention are provided. When the laying unit 2 is placed on the bracket 1, the two fixing units 3 are arranged along the inclined direction of the upper end surface of the bracket 1. Since the bracket 1 in the present invention can only fix two photovoltaic panels 11 in the inclined direction of the upper end surface of the bracket 1, the two fixing units 3 can correspond to the two photovoltaic panels 11 respectively. When laying, the laying unit 2 is first placed on the upper end surface of the bracket 1. There are multiple photovoltaic panels 11 in the laying unit 2. The laying unit 2 can lay the photovoltaic panel 11 on the specified position of the bracket 1. The upper end surface of the bracket 1 is provided with a through hole 14 that coincides with the lower mounting hole 111 of the photovoltaic panel 11. When the laying unit 2 lays the photovoltaic panel 11 on the bracket 1, the mounting hole 111 on the photovoltaic panel 11 coincides with the through hole 14. The positioning process of the mounting hole 111 and the through hole 14 is a prior art and will not be repeated here. When the laying unit 2 is placed on the upper end surface of the bracket 1, the extension arm 31 rotatably arranged on the laying unit 2 is in a working state. As the laying unit 2 moves on the bracket 1 along the length direction of the bracket 1, the extension arm 31 moves synchronously with the laying unit 2. When the extension arm 31 passes through the vertical rod 12, the extension arm 31 is pushed to rotate by the vertical rod 12. At this time, the planetary end of the extension arm 31 rotates around the rotating end, and the electric screwdriver 32 arranged on the planetary end rotates synchronously with the planetary end around the rotating end. The extension arm 31 switches from the working state to the avoidance state. A driving device is arranged on the rotating end of the extension arm 31. The resetting unit 33 of the extension arm 31 rotates and resets. When the extension arm 31 passes the vertical rod 12, the resetting unit 33 drives the extension arm 31 to rotate from the avoidance state to the working state. When the laying unit 2 moves to the specified position, it stops moving and places the photovoltaic panel 11 on the bracket 1. At this time, the extension arm 31 has been reset by the resetting unit 33. The extension arm 31 is in the working state. The working end of the electric screwdriver 32 set on the extension arm 31, the through hole 14 on the bracket 1 and the mounting hole 111 of the photovoltaic panel 11 are all in a straight line. At this time, the electric screwdriver 32 can fix the photovoltaic panel 11. After the fixation is completed, the laying unit 2 continues to move along the length direction of the bracket 1.

[0036] By arranging an extension arm 31 at the lower part of the laying unit 2, one end of the extension arm 31 is rotatably matched with the laying unit 2, and the extension arm 31 has a working state and an avoidance state during the rotation process, and the two states of the extension arm 31 are adjusted by the reset unit 33, so that when the extension arm 31 moves with the laying unit 2, the extension arm 31 is in the working state when it is not in contact with the vertical rod 12, and the extension arm 31 is in the avoidance state when it is in contact with the vertical rod 12. After the extension arm 31 completely passes through the vertical rod 12, the reset unit 33 drives the extension arm 31 to rotate from the avoidance state to the working state. In the working state, the electric screwdriver 32 on the extension arm 31 coincides with the through groove on the bracket 1 and the mounting hole 111 on the photovoltaic panel 11. In summary, the present invention reduces the workload of the staff and improves the installation efficiency of the photovoltaic panel 11.

[0037] Reference Figure 6 : The resetting unit 33 includes a first rotation driver 331 which can drive the extension arm 31 to rotate.

[0038] The extension arm 31 switches between the avoidance state and the working state by its own rotation. The first rotation driver 331 is preferably a servo motor. After the extension arm 31 passes through the vertical rod 12, the first rotation driver 331 starts and drives the extension arm 31 to rotate and reset to the working state. When the extension arm 31 is in the working state, when the extension arm 31 moves synchronously with the laying unit 2, the vertical rod 12 blocks the moving path of the extension arm 31. When the extension arm 31 is in the avoidance state, the vertical rod 12 does not block the moving path of the extension arm 31.

[0039] Reference Fig. 9 A rotating sleeve 332 is fixedly arranged on the rotating end of the extension arm 31, and a plurality of one-way teeth 3321 are fixedly arranged on the inner wall of the rotating sleeve 332 around the axis of the rotating sleeve 332. A rotating column 333 is fixedly arranged on the output end of the first rotation driver 331, and the rotating column 333 extends into the rotating sleeve 332. A spring piece 3331 is fixedly and obliquely arranged on the side wall of the rotating column 333, and the spring piece 3331 is unidirectionally meshed with the one-way teeth 3321, and the elastic force of the spring piece 3331 when bending over the one-way teeth 3321 is greater than the total weight of the extension arm 31 provided with the electric screwdriver 32.

[0040] Reference Figure 1-Figure 12 When the extension arm 31 rotates to a horizontal state, the weight of the electric screwdriver 32 exerts a maximum force on the extension arm 31, and the elastic force of the spring piece 3331 when it bends over the one-way tooth 3321 is greater than the force.

[0041] Reference Figure 6 and Fig. 9 A torsion spring box 334 is also provided on the rotating end of the extension arm 31, and the torsion spring box 334 and the rotating sleeve 332 are respectively provided at the lower part and the upper part of the extension arm 31.

[0042] The torsion spring in the torsion spring box 334 provides torque to the extension arm 31, so that the load of the first rotation driver 331 is reduced in the process of driving the extension arm 31 to change from the avoidance state to the working state. At the same time, as the extension arm 31 provided with the electric screwdriver 32 rotates from the working state to the avoidance state, the downward rotation force applied by the electric screwdriver 32 to the extension arm 31 gradually increases. This is because the extension arm 31 gradually tends to a horizontal state during the rotation process, and the force exerted by the weight of the electric screwdriver 32 on the planetary end of the extension arm 31 also gradually increases. In order to avoid the extension arm 31 continuing to rotate after passing the vertical rod 12 because the elastic force of the spring piece 3331 is less than the force exerted by the electric screwdriver 32 on the planetary end of the extension arm 31, the winding spring box provided at the rotating end of the extension arm 31 can also reduce the load of the spring piece 3331, thereby extending the service life of the spring piece 3331. When the first rotary driver 331 drives the rotating column 333 to rotate, the rotating column 333 presses and rotates the one-way tooth 3321 through the spring piece 3331, thereby causing the rotating sleeve 332 to rotate. The extension arm 31 rotates from the avoidance state to the working state under the action of the first rotary driver 331. When the extension arm 31 switches to the working state, the working end of the electric screwdriver 32, the through hole 14 on the bracket 1, and the mounting hole 111 of the photovoltaic panel 11 are all in a straight line. At this time, the electric screwdriver 32 can fix the photovoltaic panel 11.

[0043] Reference Fig.12 A limit block 335 is provided at one end of the extension arm 31. When the extension arm 31 rotates to the working state, it contacts the limit block 335 and stops rotating.

[0044] In actual operation, a pressure sensor can be set on the limit block 335 to monitor the position status of the extension arm 31. When the pressure sensor is set on the limit block 335, after the first rotary driver 331 drives the extension arm 31 to contact the limit block 335, the pressure sensor detects the pressure value, which means that the extension arm 31 is in contact with the limit block 335. The first rotary driver 331 stops rotating, and the working end of the electric screwdriver 32, the through hole 14 on the bracket 1, and the mounting hole 111 of the photovoltaic panel 11 are all in a straight line. At this time, the electric screwdriver 32 can fix the photovoltaic panel 11.

[0045] Reference Figure 5 and Figure 8 : A driving trolley 4 is provided on one side of the laying unit 2 for driving the laying unit 2 to move along the length direction of the bracket 1.

[0046] Reference Figure 4 and Fig.11A lifting sleeve 42 is vertically arranged above the driving trolley 4, and a lifting rod 41 is slidably arranged in the lifting sleeve 42 along the extension direction of the lifting sleeve 42. The lifting rod 41 extends from the upper part of the lifting sleeve 42, and an air pump 421 and a switch valve 422 are arranged on the side wall of the lifting sleeve 42. The air pump 421 and the switch valve 422 are both connected to the lifting sleeve 42.

[0047] During the movement of the driving trolley 4, the driving trolley 4 will bump in the vertical direction, causing the distance between the driving trolley 4 and the laying unit 2 to change in the vertical direction. In order to ensure that the driving trolley 4 will not fail to drive the laying unit 2 due to the change in the distance between the driving trolley 4 and the laying unit 2 in the height direction when pushing the laying unit 2 along the length direction of the bracket 1, a lifting rod 41 and a lifting sleeve 42 are provided. When the laying unit 2 is placed on the bracket 1, the switch valve 422 is opened, and the lifting rod 41 and the lifting sleeve 42 slide freely in the vertical direction. When the driving trolley 4 bumps in the vertical direction during the movement, the lifting rod 41 and the lifting sleeve 42 slide relative to each other, and the driving trolley 4 can still drive the laying unit 2 through the lifting rod 41 and the lifting sleeve 42. The air pump 421 can adjust the height of the laying unit 2 when the laying unit 2 is not placed on the bracket 1. When the air pump 421 is running, the switch valve 422 is in a closed state.

[0048] Reference Figure 5 , Figure 8 and Fig.10 A support frame 43 for supporting the laying unit 2 is hingedly connected to the upper part of the lifting rod 41, a slide 45 is fixedly arranged on the support frame 43 along the width direction of the support frame 43, the laying unit 2 is movably arranged on the slide 45 along the extension direction of the slide 45, and a second rotation driver 44 for driving the support frame 43 to rotate is arranged at the lower part of the support frame 43.

[0049] When the laying unit 2 is placed on the bracket 1, the second rotary driver 44 drives the support frame 43 to rotate. Since the inclination angle of the upper end surface of the bracket 1 is known, after the second rotary driver 44 rotates the support frame 43 to the same inclination angle as the upper end surface of the bracket 1, the slide 45 allows the laying unit 2 to slide out. After the laying unit 2 completely slides out from the slide 45, it can move along the length direction of the bracket 1. The second rotary driver 44 is preferably a servo motor.

[0050] Reference Figure 7 The laying unit 2 comprises a plurality of rollers 21, and the rollers 21 are in rolling cooperation with the highest position of the upper end surface of the bracket 1 along the length direction of the bracket 1.

[0051] The friction coefficient between the laying unit 2 and the bracket 1 is reduced by the rolling cooperation between the roller 21 and the highest position of the upper end surface of the bracket 1.

[0052] Working principle: When laying, first place the laying unit 2 on the upper end surface of the bracket 1. There are multiple photovoltaic panels 11 in the laying unit 2. The laying unit 2 can lay the photovoltaic panel 11 on the specified position of the bracket 1. A through hole 14 is opened on the upper end surface of the bracket 1, which coincides with the lower mounting hole 111 of the photovoltaic panel 11. When the laying unit 2 lays the photovoltaic panel 11 on the bracket 1, the mounting hole 111 on the photovoltaic panel 11 coincides with the through hole 14. The positioning process of the mounting hole 111 and the through hole 14 is a prior art and will not be repeated here. When the laying unit 2 is placed on the upper end surface of the bracket 1, the extension arm 31 rotatably arranged on the laying unit 2 is in a working state. As the laying unit 2 moves on the bracket 1 along the length direction of the bracket 1, the extension arm 31 moves synchronously with the laying unit 2. When the extension arm 31 passes through the vertical rod 12, the extension arm 31 is pushed to rotate by the vertical rod 12. At this time, the planetary end of the extension arm 31 rotates around the rotating end, and the electric screwdriver 32 arranged on the planetary end rotates synchronously with the planetary end around the rotating end. The extension arm 31 switches from the working state to the avoidance state. A driving device is arranged on the rotating end of the extension arm 31. The resetting unit 33 of the extension arm 31 rotates and resets. When the extension arm 31 passes the vertical rod 12, the resetting unit 33 drives the extension arm 31 to rotate from the avoidance state to the working state. When the laying unit 2 moves to the specified position, it stops moving and places the photovoltaic panel 11 on the bracket 1. At this time, the extension arm 31 has been reset by the resetting unit 33. The extension arm 31 is in the working state. The working end of the electric screwdriver 32 set on the extension arm 31, the through hole 14 on the bracket 1 and the mounting hole 111 of the photovoltaic panel 11 are all in a straight line. At this time, the electric screwdriver 32 can fix the photovoltaic panel 11. After the fixation is completed, the laying unit 2 continues to move along the length direction of the bracket 1.
