Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic bracket production, and specifically provides a photovoltaic bracket production device and method. Background Art

[0002] Photovoltaic is a technology that converts light energy into electrical energy, mainly relying on the photovoltaic effect. The core part of a photovoltaic system is a photovoltaic cell, usually made of silicon material. These cells can directly convert the received sunlight into current. Photovoltaic cells are mostly installed and supported by photovoltaic brackets. Common materials for photovoltaic brackets include aluminum, hot-dip galvanized steel, and stainless steel, etc., which can improve the durability and corrosion resistance of the brackets.

[0003] Most traditional photovoltaic bracket production processes first roll and form steel bars to produce long C-shaped steel, then perform segmented cutting and punching operations on the long C-shaped steel, and finally perform surface treatment on the C-shaped steel according to requirements. However, when performing segmented cutting and punching operations on the C-shaped steel, depressions and burrs are likely to form at the end face of the C-shaped steel or the inner wall of the punched hole of the C-shaped steel. Subsequently, it is necessary to separately trim and polish the end face position or the inner wall position of the punched hole of the C-shaped steel, resulting in a relatively low overall production and processing efficiency of the photovoltaic bracket. For this reason, we propose a photovoltaic bracket production device and method to solve the above problems. Summary of the Invention

A longitudinal contact rod is arranged outside the transmission gear, and a transmission rack corresponding to the transmission gear is arranged at the bottom of the longitudinal contact rod.

[0014] A use method of a photovoltaic bracket production device includes the following steps:

[0015] Step 1: According to the length of the inner top wall of the photovoltaic bracket, select top support side rollers with appropriate lengths and install them on both sides of the top support middle roller, so that the sum of the lengths of the top support middle roller and the two top support side rollers is the same as the length of the inner top wall of the photovoltaic bracket;

[0016] According to the length of the inner bottom wall of the photovoltaic bracket, rotate the bottom support side rollers so that the side ends of the two bottom support side rollers at the positions are respectively in contact with the inner side walls of the photovoltaic bracket.

[0017] According to the distance between the inner top wall and the inner bottom wall of the photovoltaic bracket, use tools to rotate the two lifting screws to drive the longitudinal sliding seat to rise and fall, thereby controlling the lifting of the bottom support side rollers, so that the outer surfaces of the top support middle roller and the two top support side rollers are in contact with the inner top wall of the photovoltaic bracket, and the outer surface of the bottom support side roller is in contact with the inner bottom wall of the photovoltaic bracket;

[0018] Step 2: After the photovoltaic bracket is processed and formed by the forming roller, it is transmitted to the position of the inner support device, so that the outer surfaces of the top support middle roller and the two top support side rollers are in contact with the inner top wall of the photovoltaic bracket, and the outer surface of the bottom support side roller is in contact with the inner bottom wall of the photovoltaic bracket, so as to internally support the transmitted photovoltaic bracket through the top support middle roller, the two top support side rollers and the bottom support side rollers;

[0019] Until the cutting part of the photovoltaic bracket is automatically transmitted between the two longitudinal support frames, control the opening of the first motor to drive the first auxiliary shaft to rotate, cooperate with the transmission of the two first sprockets and the first chain, drive the cutting cutter head to rotate at high speed, and then control the opening of the first linear electric rail to drive the cutting cutter head to descend, and automatically cut the cutting part of the internally supported photovoltaic bracket from top to bottom;

[0020] Step 3: After the photovoltaic bracket is cut and processed, continue to be transmitted so that the punching position of the photovoltaic bracket moves between the upper punching part and the lower support part, and the punching position of the photovoltaic bracket corresponds to the punching rod position. Subsequently, control the lower support part to rise steadily so that the upper surface of the lower support seat is in contact with the inner top wall of the photovoltaic bracket, and internally support the punching position of the photovoltaic bracket through the lower support seat;

[0021] Immediately, the control makes the upward punching part descend stably. The top pressing seat first contacts the upper surface of the photovoltaic bracket for positioning, and continues to descend. The punching rod inserts into the punching rod clamping hole and stably passes through the photovoltaic bracket to perform stable punching processing on it. The generated waste is discharged through the punching hole.

[0022] Step 4: After the punching processing of the photovoltaic bracket is completed, the photovoltaic bracket continues to be transmitted. At the same time, the control turns on the second motor to drive the second auxiliary shaft to rotate. With the transmission of the second sprocket and the second chain, the control makes the grinding roller rotate to perform internal automatic grinding operation on the punching position of the photovoltaic bracket to remove the burrs generated on the inner wall of the punching position of the photovoltaic bracket.

[0023] Step 5: After the internal grinding of the punching position of the photovoltaic bracket, it continues to be transmitted to make the punching position of the photovoltaic bracket vertically correspond to the position of the longitudinal clamping column. Subsequently, turn on two second linear electric rails to drive the longitudinal clamping column to drive the magnetic attraction ring and the fixing nut to move upward, so that the top of the longitudinal clamping column is movably clamped in the punching position of the photovoltaic bracket. At this time, the upper surface of the fixing nut contacts the inner top wall of the punching position of the photovoltaic bracket to perform precise positioning of the fixing nut and the punching position of the photovoltaic bracket. Immediately, turn on multiple welding heads to perform multi-point welding of the fixing nut on the inner top wall of the punching position of the photovoltaic bracket.

[0024] Subsequently, the control turns on the third motor to drive the driving gear to rotate, thereby controlling the rotating toothed ring and multiple welding heads to rotate to perform automatic full welding on the fixing nut.

[0025] Step 6: When the fixing nut is automatically fully welded to the inner top wall of the punching position of the photovoltaic bracket, the control turns on two second linear electric rails to drive the longitudinal clamping column to drive the magnetic attraction ring to move downward. The magnetic attraction ring and the fixing nut are separated until the longitudinal clamping column disengages from the photovoltaic bracket, and the transmission gear and the transmission rack are engaged. Continue to move downward, and the transmission rack drives the transmission gear to control the worm to drive the worm gear to rotate, thereby controlling the turning shaft, the longitudinal clamping column and the magnetic attraction ring to turn, so that the longitudinal clamping column corresponds to the position of one of the fixing nuts to be welded on the transmission mechanism. Continue to descend, the transmission gear is no longer engaged with the transmission rack, the bottom of the longitudinally clamped column after flipping inserts into the to-be-welded fixing nut, and the magnetic attraction ring and the fixing nut are magnetically fixed. Subsequently, the control makes the longitudinal clamping column drive the magnetic attraction ring and the magnetically attracted fixing nut to move upward, the transmission gear and the transmission rack are engaged again, and continue to move upward. Again, control the turning shaft, the longitudinal clamping column and the magnetic attraction ring to reverse and return to their original positions, so that the fixing nut is moved to the upper side for subsequent welding and fixing of the fixing nut.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. By setting the inner support device and cooperating with the cutting device, the top support middle roller and the two side top support rollers and the bottom support side roller support the transmitted photovoltaic bracket internally, preventing the photovoltaic bracket from generating internal deformation during automatic cutting of the photovoltaic bracket, which affects subsequent installation, and there is no need to trim the cross section of the photovoltaic bracket subsequently.

[0028] 2. By setting up a punching device to perform automatic internal support punching operation on the photovoltaic support, it prevents the occurrence of concave deformation at the punching position of the photovoltaic support, which may affect the connection and installation of two adjacent and intersecting photovoltaic supports in the subsequent process.

[0029] 3. By setting up a grinding device to perform automatic internal grinding operation on the punching position of the photovoltaic support, it prevents the generation of burrs on the inner wall of the punching position of the photovoltaic support, which may affect the welding and fixing of the subsequent fixing nut.

[0030] 4. By setting up an auxiliary welding device, it realizes the auxiliary welding and fixing of the fixing nut, so as to facilitate the subsequent rapid connection and installation of two adjacent and intersecting photovoltaic supports by directly using a fixing bolt. There is no need to manually hold and position the fixing nut inside the photovoltaic support when fixing two adjacent and intersecting photovoltaic supports subsequently. In this way, it is convenient for the connection and fixing of two adjacent and intersecting photovoltaic supports, and the automatic feeding of the fixing nut can be carried out.

With the transmission of the second sprockets 54 and the second chain 541, the grinding roller 52 is controlled to rotate, and an internal automatic grinding operation is performed on the punching position of the photovoltaic bracket to prevent burrs from being generated on the inner wall of the punching position of the photovoltaic bracket, which may affect the subsequent welding and fixing of the fixing nut 66.

The head positions of the welding heads 672 correspond to the top positions of the fixing nut 66. After the inner part of the punching position of the photovoltaic bracket is ground, it continues to be conveyed, so that the punching position of the photovoltaic bracket is vertically corresponding to the position of the longitudinal clamping column 65. Subsequently, the two second linear electric rails 61 are turned on to drive the longitudinal clamping column 65 to drive the magnetic attraction ring 651 and the fixing nut 66 to move upward, so that the top of the longitudinal clamping column 65 is movably clamped in the punching position of the photovoltaic bracket. At this time, the upper surface of the fixing nut 66 contacts the inner top wall of the punching position of the photovoltaic bracket, and the precise positioning of the fixing nut 66 and the punching position of the photovoltaic bracket is carried out. Immediately afterwards, a plurality of welding heads 672 are turned on to multi-point weld the fixing nut 66 to the inner top wall of the punching position of the photovoltaic bracket;

The bottom of the longitudinal clamping column 65 after turning is inserted into the fixing nut 66 to be welded, and the magnetic attraction ring 651 is magnetically fixed to the fixing nut 66, realizing the automatic feeding of the fixing nut 66 for the subsequent continuous welding use of the fixing nut 66. Subsequently, the longitudinal clamping column 65 is controlled to drive the magnetic attraction ring 651 and the magnetically attracted fixing nut 66 to move upwards. The transmission gear 633 is meshed with the transmission rack 6341 again. Continuing to move upwards, the turning shaft 63, the longitudinal clamping column 65 and the magnetic attraction ring 651 are controlled to turn in the reverse direction and reset again, moving the fixing nut 66 to the upper side for the subsequent welding and fixing of the fixing nut 66.

[0059] A method for using a photovoltaic bracket production device includes the following steps:

[0060] Step 1. According to the length of the inner top wall of the photovoltaic support, select the top support side rollers 331 with appropriate lengths and install them on both sides of the top support middle roller 33, so that the total length of the top support middle roller 33 and the two top support side rollers 331 is the same as the length of the inner top wall of the photovoltaic support;

[0061] According to the length of the inner bottom wall of the photovoltaic support, rotate the bottom support side roller 35 so that the side ends of the two bottom support side rollers 35 in position are respectively in contact with the inner side walls of the photovoltaic support;

[0062] According to the distance between the inner top wall and the inner bottom wall of the photovoltaic support, use tools to rotate the two lifting screws 36 to drive the longitudinal sliding seat 321 to rise and fall, thereby controlling the lifting of the bottom support side roller 35, so that the outer surfaces of the top support middle roller 33 and the two top support side rollers 331 are in contact with the inner top wall of the photovoltaic support, and the outer surface of the bottom support side roller 35 is in contact with the inner bottom wall of the photovoltaic support;

[0063] Step 2. After the photovoltaic support is processed and formed by the forming roller, it is transmitted to the position of the inner support device 3, so that the outer surfaces of the top support middle roller 33 and the two top support side rollers 331 are in contact with the inner top wall of the photovoltaic support, and the outer surface of the bottom support side roller 35 is in contact with the inner bottom wall of the photovoltaic support, so as to internally support the transmitted photovoltaic support through the top support middle roller 33, the two top support side rollers 331 and the bottom support side roller 35;

[0064] Until the cutting part of the photovoltaic support is automatically transmitted between the two longitudinal support frames 32, control the first motor 262 to start to drive the first auxiliary shaft 25 to rotate. With the transmission of the two first sprockets 26 and the first chain 261, drive the cutting tool disc 24 to rotate at high speed. Then control the first linear electric rail 21 to start to drive the cutting tool disc 24 to descend, and automatically cut the cutting part of the internally supported photovoltaic support from top to bottom;

[0065] Step 3. After the photovoltaic support is cut and processed, continue to be transmitted so that the punching position of the photovoltaic support moves between the upper punching part 43 and the lower support part 45, and make the punching position of the photovoltaic support correspond to the position of the punching rod 434. Subsequently, control the lower support part 45 to rise stably, so that the upper surface of the lower support seat 454 is in contact with the inner top wall of the photovoltaic support, and internally support the punching position of the photovoltaic support through the lower support seat 454;

[0066] Immediately control the upper punching part 43 to descend stably. The top pressure seat 433 first contacts the upper surface of the photovoltaic support for positioning. Continue to descend, and the punching rod 434 is inserted into the punching rod clamping hole and stably passes through the photovoltaic support to perform stable punching processing on it. The generated waste is discharged through the punching hole 4541;

[0067] Step 4: After the punching process of the photovoltaic support is completed, the photovoltaic support continues to be conveyed. Meanwhile, the second motor 55 is controlled to start, driving the second auxiliary shaft 53 to rotate. With the transmission of the second sprocket 54 and the second chain 541, the grinding roller 52 is controlled to rotate, and internal automatic grinding operation is performed on the punching position of the photovoltaic support to remove the burrs generated on the inner wall of the punching position of the photovoltaic support.

[0068] Step 5: After the internal grinding of the punching position of the photovoltaic support, it continues to be conveyed, making the punching position of the photovoltaic support and the position of the longitudinal clamping column 65 vertically correspond. Subsequently, two second linear electric rails 61 are started to drive the longitudinal clamping column 65 to drive the magnetic attraction ring 651 and the fixing nut 66 to move upward, so that the top of the longitudinal clamping column 65 is movably clamped in the punching position of the photovoltaic support. At this time, the upper surface of the fixing nut 66 contacts the inner top wall of the punching position of the photovoltaic support, and precise positioning of the fixing nut 66 and the punching position of the photovoltaic support is carried out. Immediately, multiple welding heads 672 are started to perform multi-point welding of the fixing nut 66 on the inner top wall of the punching position of the photovoltaic support.

[0069] Subsequently, the third motor 674 is controlled to start, driving the driving gear 673 to rotate, thereby controlling the rotating gear ring 671 and multiple welding heads 672 to rotate, and automatically performing full welding on the fixing nut 66.

[0070] Step 6: After the fixing nut 66 is automatically fully welded to the inner top wall of the punching position of the photovoltaic support, two second linear electric rails 61 are controlled to start, driving the longitudinal clamping column 65 to drive the magnetic attraction ring 651 to move downward. The magnetic attraction ring 651 is separated from the fixing nut 66 until the longitudinal clamping column 65 is separated from the photovoltaic support, and the transmission gear 633 and the transmission rack 6341 are engaged. Continuing to move downward, the transmission rack 6341 drives the transmission gear 633 to control the worm 632 to drive the worm gear 631 to rotate, thereby controlling the turning shaft 63, the longitudinal clamping column 65 and the magnetic attraction ring 651 to turn, so that the longitudinal clamping column 65 corresponds to the position of one of the fixing nuts 66 to be welded on the transmission mechanism 7. Continuing to descend, the transmission gear 633 is no longer engaged with the transmission rack 6341. The bottom of the turned longitudinal clamping column 65 is inserted into the fixing nut 66 to be welded, and the magnetic attraction ring 651 and the fixing nut 66 are magnetically fixed. Subsequently, the longitudinal clamping column 65 is controlled to drive the magnetic attraction ring 651 and the magnetically attracted fixing nut 66 to move upward. The transmission gear 633 and the transmission rack 6341 are engaged again. Continuing to move upward, the turning shaft 63, the longitudinal clamping column 65 and the magnetic attraction ring 651 are controlled to turn in the reverse direction to reset, moving the fixing nut 66 to the upper side for subsequent welding and fixing of the fixing nut 66.
