Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and particularly to an efficient welding device for a photovoltaic bracket drive base assembly and a welding method thereof. Background Art

[0002] Solar photovoltaic power generation is one of the most important forms of solar energy utilization at present. In order to improve the power generation and economic benefits of a photovoltaic power station, a photovoltaic tracking bracket can be adopted. Through a photovoltaic tracking system, it is used to assist photovoltaic modules to accurately track the sun, improve the solar energy utilization rate. One of the photovoltaic tracking systems is to control the bracket by calculating the sun's movement trajectory, so that the bracket rotates regularly at a certain angle, and is connected to the photovoltaic tracking system through a drive base device, and the angle adjustment of the photovoltaic module is realized through a drive device.

[0003] In a photovoltaic tracking system, usually a row of photovoltaic panels are installed on a rotatable photovoltaic main shaft, and multiple support columns are arranged on the ground to support the photovoltaic main shaft. By driving the rotation of the photovoltaic main shaft, the orientation of the photovoltaic panels is adjusted so as to track the sun movement in real time. And a support bearing is required to connect the photovoltaic main shaft and the support column. Usually, a pair of mounting side plates are arranged at the lower end of the support bearing and are connected to the support column through bolt connection. A ring sleeve is arranged at the upper end of the mounting side plate and is sleeved outside the photovoltaic main shaft as a support. During the processing of the support bearing housing, it is necessary to weld and fix the two.

[0004] In the current processing technology, usually a welding tooling is used to limit the ring sleeve and a pair of side plates, and then a welding manipulator is used for welding. However, when the mounting side plates need to be loaded, it is still necessary to manually pick and load them one by one. Some enterprises are equipped with intelligent loading manipulators for automatic loading, but the manipulator still picks and loads a single mounting side plate each time and cannot load a pair of mounting side plates in place at one time, resulting in low work efficiency.

[0005] Therefore, it is necessary to provide an efficient welding device for a photovoltaic bracket drive base assembly and a welding method thereof, which can achieve the effect of facilitating welding. Summary of the Invention

[0018] The disclosure below provides many different embodiments or examples for realizing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0019] See also Figure 1-13 The present invention provides a technical solution: an efficient welding device and a welding method for a photovoltaic support drive base assembly, comprising a welding table 4, A conveyor 8 is provided on the upper side of the welding table 4. A pair of discharge ports 801 and a diversion mechanism are provided at the end of the conveyor 8. The diversion mechanism includes a pair of discharge vertical plates 1 and a top block 101. The discharge channel is opened through the interior of the discharge vertical plate 1. The pair of discharge ports 801 are connected to the discharge vertical plate 1. The top block 101 is pushed upward from the middle of the pair of mounting side plates 7. The mounting side plates 7 tilt to both sides and fall into the discharge port 801. A limiting fixture is provided on the upper side of the welding table 4, which limits the position of a pair of mounting side plates 7 and makes them contact with the support ring sleeve 6; A clamping rod 1 401 is fixedly connected to the middle side of the welding table 4 , and a pair of movable clamping rods 2 402 are provided on one side of the clamping rod 1 401 . The clamping rod 1 401 cooperates with the clamping rod 2 402 to clamp the support ring sleeve 6 .

[0020] The mounting side plates 7 to be welded are transported through the conveyor track 8 with a distance difference between each mounting side plate 7. A number of driving rollers are provided at the upper end of the conveyor track 8 to drive and transport the mounting side plates 7 until the two mounting side plates 7 are transported into the shunting mechanism at the end; at this time, a pair of mounting side plates 7 are located between a pair of blanking ports 801. The top block 101 jacks up from between the pair of mounting side plates 7, causing the two mounting side plates 7 to tilt to both sides and fall into the blanking ports 801. The pair of mounting side plates 7 fall along the blanking channel in the blanking vertical plate 1 into the limiting tooling on the welding table 4, thus completing the synchronous feeding of a pair of mounting side plates 7 and improving the feeding efficiency; Then, the support ring sleeve 6 is manually fed and sleeved on the outside of the first clamping rod 401. A moving block 403 is provided at the lower end of the second clamping rod 402. The second clamping rod 402 passes through the welding table 4 and is connected to the moving block 403. The moving block 403 is driven by a linear driving mechanism (the linear driving mechanism includes but is not limited to a cylinder or a lead screw mechanism). The moving block 403 drives the second clamping rod 402 to move relatively, applying a thrust to one end of the support ring sleeve 6 until the inner wall of the support ring sleeve 6 abuts tightly against the first clamping rod 401, thus clamping and positioning it. The structure is simple and can clamp support ring sleeves 6 with various diameters, with strong versatility; then, the limiting tooling drives a pair of mounting side plates 7 to displace relative to the support ring sleeve 6 until they are butted against each other. Then, the welding seam can be welded by a welding manipulator and a welding gun (the welding manipulator is an existing technology in the welding field, so it will not be elaborated here), thereby realizing the welding process of the support bearing housing.

[0021] The distance between a pair of blanking ports 801 is equal to the total length of a pair of mounting side plates 7, and the cross-section of the blanking port 8 is in the shape of a right trapezoid; A baffle 102 is arranged in the inclined plane of the blanking port 801. The upper end of the baffle 102 is in the shape of an inverted hook. The baffle 102 penetrates through the bottom of the conveyor track 8 and is in sliding fit with it.

[0022] Preferably, the cross-section of the blanking port 801 is in the shape of a right trapezoid with a circular chamfer at one end, so as to expand the falling range of the mounting side plate 7; Preferably, in order to further increase the angle when the mounting side plate 7 is jacked up, so as to ensure smooth blanking and avoid the situation that when the inclination angle is too small, the mounting side plate 7 slides to both sides by itself and finally forms a horizontal state, resulting in its inability to enter the blanking port 801 (such as Figure 4As shown in the figure, extension arc plates are added at both ends of the top block 101, and a liftable baffle 102 is arranged in the blanking port 801. Specifically, when the top block 101 jacks up, the baffles 102 on both sides also move upward and extend to the upper end of the blanking port 801, thus blocking at the blanking port 801 to limit the side slip of the mounting side plate 7. The top block 101 and the extension arc plates continue to move upward, causing the pair of mounting side plates 7 to gradually increase the angle. When the inclination angle reaches the maximum, the baffle 102 descends and resets to release the limit on the mounting side plate 7, enabling the inclined mounting side plate 7 to fall into the blanking port 801, ensuring the stable blanking of the mounting side plate 7.

[0023] The lower end of the baffle 102 is in a T shape, and a pair of ejector rods 106 are in contact with the lower end of the baffle 102. When the pair of ejector rods 106 separate from each other, the support for the baffle 102 is released; A cylinder 103 is arranged between a pair of blanking vertical plates 1. The driving end of the cylinder 103 is fixedly connected with a lifting plate 104. A plurality of guide rods 105 are fixedly connected to the bottom of the conveying channel 8. The guide rods 105 penetrate through the lifting plate 104 and are slidably matched with it. The top block 101 is fixed to the middle end of the lifting plate 104. A square opening is opened at the lower end of the top block 101, and the ejector rod 106 passes through the square opening.

[0024] Preferably, the baffle 102 is pushed upward by a pair of ejector rods 106 to limit the mounting side plate 7. When the limit needs to be released, the pair of ejector rods 106 move away from each other, and the baffle 102 loses the support of the ejector rods 106 and falls and resets under the action of gravity; Preferably, when the top block 101 needs to be driven to lift, the lifting plate 104 is driven by the cylinder 103, and the guide rods 105 are used for guiding. The lifting plate 104 can drive the top block 101 to lift.

[0025] A vertical rod 107 is vertically arranged in the square opening. The lower end of the vertical rod 107 is fixedly connected with the lifting plate 104. A first spring member is arranged outside the vertical rod 107. The vertical rod 107 penetrates through and is slidably matched with a slider 108. A pair of extension rods 109 are fixedly connected to both ends of the slider 108. Vertical grooves are opened on the inner sides of both ends of the square opening. One end of the extension rod 109 is fixedly connected with a guide block 112. The guide block 112 is slidably matched with the vertical groove. The extension rod 109 penetrates through the ejector rod 106 and is slidably matched with it. A second spring member is sleeved outside the extension rod 109. A pair of square wedges 110 are fixedly connected to the upper end of the lifting plate 104. Chamfered bevels are opened at both ends of the square wedge 110. Triangular inclined grooves 111 are correspondingly opened at the lower end of the ejector rod 106. Square grooves are opened at both ends of the lifting plate 104.

[0026] Preferably, a slider 108 is arranged in the middle of a pair of ejector rods 106. The ejector rods 106 slide along the extension rod 109 for guiding. And due to the elastic force of the second spring, the ejector rods 106 are in contact with the slider 108 in the initial state. Guide blocks 112 are connected to both ends of the extension rod 109. The guide blocks 112 are guided along the vertical grooves in the square opening. The slider 108 is guided along the vertical rod 107. And due to the elastic force of the first spring member, the slider 108 is at the uppermost end of the square opening in the initial state. At this time, the ejector rods 106 support the baffle 102 (as Figure 3 shown). When the first cylinder 103 drives the lifting plate 104 upward, the lifting plate 104 drives the top block 101, the ejector rods 106 and the baffle 102 to rise synchronously until the ejector rods 106 contact the bottom of the conveyor path 8 and cannot move upward any further. Then the baffle 102 can limit the installation side plate 7. And the lifting plate 104 pushes the top block 101 to continue rising. The first spring is compressed. The top block 101 pushes the installation side plate 7 to continuously increase its inclination angle until the square wedge block 110 contacts the triangular inclined groove 111, causing the pair of ejector rods 106 to separate from each other along the inclined chamfer of the square wedge block 110. The baffle 102 descends and resets, enabling the inclined installation side plate 7 to be discharged from the blanking port 801. That is to say, only by the upward movement of the lifting plate 104, while the baffle 102 limits the installation side plate 7, it also realizes that when the installation side plate 7 reaches the maximum inclination angle, the limit on it is automatically released. That is, while the top block 101 drives the installation side plate 7 to incline, it also additionally controls the automatic limiting and release of the installation side plate 7. It has a high degree of automation and strong practicability.

[0027] An upper plate 802 is arranged at the upper end of the conveyor path 8. One end of the upper plate 802 is fixedly connected with a positioning plate 803; The conveyor path 8 is penetrated with a material pushing port which extends to the blanking port 801 on one side. A material pushing plate 3 is arranged in the material pushing port. A convex wedge block 301 is arranged at one end of the material pushing port. One end of the material pushing plate 3 is provided with an inclined chamfer. The convex wedge block 301 is adapted to the inclined chamfer of the material pushing plate 3. A second guide rod 302 is fixedly connected to the lower end of the material pushing plate 3. The lower end of the second guide rod 302 is slidably fitted with a moving plate 303. The moving plate 303 is driven to move by the second cylinder. A third spring member is arranged outside the second guide rod 302.

[0028] Preferably, in order to ensure that a pair of installation side plates 7 are accurately displaced between a pair of blanking ports 801, a positioning plate 803 is provided. Four upright posts are arranged at the upper end of the conveyor path 8 and penetrate through the upper plate 802 for guiding. In the initial state, the positioning plate 803 limits the installation side plates 7 (as Figure 2As shown in the figure), thus preventing the installation side plate 7 from displacing too much and covering the blanking port 801, ensuring the accurate blanking position of the installation side plate 7. Then, when the top block 101 moves upward, the upper plate 802 is lifted, driving the positioning plate 803 to rise, releasing the limit on the installation side plate 7, enabling it to discharge materials normally; Preferably, the moving plate 303 is driven by the second cylinder to displace, thereby pushing the installation side plate 7 into the space between a pair of blanking ports 801. Then, the moving plate 303 resets and contacts the convex wedge block 301. The inclined surfaces of the two are in contact, causing the moving plate 303 to retract downward. Then, the next installation side plate 7 can be displaced to the blanking port 801. The moving plate 303 extends beyond the convex wedge block 301 and pushes it, causing a pair of installation side plates 7 to contact each other and be restricted by the positioning plate 803, thereby ensuring that a pair of installation side plates 7 accurately enter the space between a pair of blanking ports 801.

[0029] The limiting tooling includes a pair of inner clamping plates 2. An outer clamping plate 201 is arranged on the outer side of the inner clamping plate 2. A translation seat 202 is arranged between the pair of inner clamping plates 2. Guide rods three 203 are fixedly connected to both ends of the translation seat 202. The guide rods three 203 penetrate through the inner clamping plate 2 and the outer clamping plate 201 and are in sliding fit with them. The translation seat 202 is driven by the third cylinder to move. Support disks 204 are fixedly connected to both lower ends of the translation seat 202. An arc-shaped groove is arranged at one end of the welding table 4. The support disks 204 slide along the arc-shaped groove.

[0030] Preferably, the installation side plate 7 is fed between the inner clamping plate 2 and the outer clamping plate 201, and the inner clamping plate 2 and the outer clamping plate 201 clamp it for limiting, ensuring the stability during welding. Moreover, the inner clamping plate 2 and the outer clamping plate 201 can drive the installation side plate 7 to slide along the guide rod three 203, thereby adjusting the distance between a pair of installation side plates 7, which can be adjusted for various widths of support columns to be installed subsequently. Then, the translation seat 202 is driven by the third cylinder to displace, thereby driving a pair of installation side plates 7 to be docked with the support ring sleeve 6, and then the welding work can be carried out. Welding can be performed according to the required installation dimensions of the support columns, with strong versatility.

[0031] A spring member four is arranged between the translation seat 202 and the inner clamping plate 2. Driving blocks 205 are fixedly connected to the inner sides of the outer clamping plates 201. The two driving blocks 205 are arranged staggeredly and penetrate through the translation seat 202. Straight tooth grooves are opened at the lower ends of the driving blocks 205. A gear one 207 and a gear two 208 are respectively meshed and connected to the lower ends of the straight tooth grooves. One end of the gear one 207 is fixedly connected to a central shaft 5. One end of the gear two 208 is fixedly connected to an outer shaft 501. The central shaft 5 penetrates through the gear two 208 and the outer shaft 501 and is rotatably connected to them. The outer shaft 501 penetrates through one of the support disks 204 and is rotatably connected to it.

[0032] Preferably, a fourth spring member is provided such that a pair of inner clamping plates 2 always generate an outward force. When the mounting side plate 7 falls between the inner clamping plates 2 and the outer clamping plates 201, the first gear 207 is driven to rotate by the central shaft 5, and the second gear 208 is driven to rotate by the outer shaft 501, and the rotation directions of the two are opposite. The first gear 207 and the second gear 208 respectively drive a pair of driving blocks 205 to displace in opposite directions through the straight tooth grooves, thereby pulling the outer clamping plates 201 on both sides to displace towards the center, cooperating with the inner clamping plates 2 to clamp the pair of mounting side plates 7. Then, when it is necessary to adjust to the required mounting spacing, as the outer clamping plates 201 continue to displace, the inner clamping plates 2 are pushed to move inward, and the fourth spring member is compressed, so that while ensuring the self-limitation of the mounting side plates 7, the spacing between the pair of mounting side plates 7 can be adjusted to adjust the mounting spacing.

[0033] A base 9 is provided on one side of the welding table 4. A motor 901 is fixedly connected to the inner side of the base 9. A first bevel gear is driven at the upper end of the motor 901. A second bevel gear 902 and a third bevel gear 903 are respectively meshed on both sides of the first bevel gear. A torque rod 904 is penetrated and fixedly connected inside the second bevel gear 902. A straight keyway is provided on the surface of the torque rod 904. A torque hole groove is provided at one end of the central shaft 5. The torque rod 904 is adapted to the torque hole groove. The torque rod 904 penetrates through the third bevel gear 903 and is rotatably connected thereto. A plurality of fourth guide rods 905 are fixedly connected to one end of the third bevel gear 903. One end of the fourth guide rods 905 penetrates through and is slidably mated with a guide ring 906. The guide ring 906 is fixed to one end of the outer shaft 501.

[0034] Preferably, the first bevel gear is driven to rotate by the motor 901. The first bevel gear drives the second bevel gear 902 and the third bevel gear 903 to rotate synchronously and in opposite directions. The second bevel gear 902 drives the torque rod 904 to rotate, and the torque can be transmitted to drive the central shaft 5 to rotate through the straight keyway. And when the translation base 202 displaces, the torque rod 904 slides relative to the torque hole groove in the central shaft 5, which does not affect the transmission of the torque. Preferably, the third bevel gear 903 drives a plurality of fourth guide rods 905 to rotate. The fourth guide rods 905 transmit torque to drive the guide ring 906 and the outer shaft 501 to rotate, and the fourth guide rods 905 penetrate through the guide ring 906 and slide therewith, which does not affect the transmission of the torque.
