The photovoltaic aluminum frame installation device provided by the patent can drive the mobile mechanism to contact the photovoltaic panel through the push mechanism, the mobile mechanism moves up and down to clean the photovoltaic panel, and the flip mechanism flips the aluminum frame and installs it on the photovoltaic panel. In this way, the edges of the photovoltaic panel can be cleaned and the aluminum frame can be installed on the photovoltaic panel at the same time.

[0004] When installing the frames of photovoltaic panels, it is usually necessary to manually align the photovoltaic panels, otherwise it is easy to cause the metal frames to be installed poorly or misaligned. At the same time, most of the existing installation equipment is for batch installation of photovoltaic panels of the same size. If there are photovoltaic panels of different sizes, it is impossible to flexibly adjust them. In addition, for photovoltaic panels of different sizes, the metal frames need to be customized in advance to meet the installation adaptability of different sizes. If the size is suddenly not compatible, quality problems such as gaps and extrusion will occur during the installation. Summary of the invention

At the same time, it is suitable for photovoltaic panels of various sizes, which improves the convenience and efficiency of the installation of the metal frame by the staff. The present invention realizes rapid laser removal of the excess part of the metal frame through the structural design of the laser head control mechanism, without the need for customized processing of the metal frame in advance, thereby avoiding quality problems such as gaps and extrusion during installation due to size mismatch of the metal frame after processing, and at the same time facilitates the cutting of photovoltaic panels of different sizes without the need for complicated operations, and has strong applicability.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The cooperation between the fixing mechanism and the clamping mechanism of the present invention realizes the automatic installation of the metal frame without manual alignment of the photovoltaic panel, thereby avoiding the situation that the metal frame is poorly installed or misaligned due to manual misalignment. At the same time, it is suitable for photovoltaic panels of various sizes, which improves the convenience and efficiency of the workers in installing the metal frame. Specifically, through the structural design of the fixing mechanism, when the photovoltaic panel needs to be placed, the protrusion is pulled to make the sliding rod pull the third fixing block to slide along the fixing plate, so that the distance between the third fixing block and the second fixing block is increased, so that it is suitable for photovoltaic panels of different sizes; then the protrusion is released, and the photovoltaic panel is fixed under the reset limit of the limit spring. In this process, the third fixing block and the second fixing block will automatically adjust the angle of the photovoltaic panel, so that manual alignment is not required, thereby improving the installation efficiency; after fixing the photovoltaic panel, the two metal frames are coated with glue and placed on the corresponding support blocks, and then the second forward and reverse circuit is started. The machine rotates the second bidirectional screw rod to make the limit strip of the clamping frame slide along the limit slide groove; at this time, the two clamping frames are close to each other so that the two clamping plates push the metal frame. Under the clamping of the clamping plates, the metal frame is inserted into the bottom edge of the photovoltaic panel to realize the installation of the metal frame; in the process of clamping the clamping plates, the position of the photovoltaic panel will also be automatically adjusted. If the clamping plate and the metal frame on one side contact the photovoltaic panel first instead of contacting at the same time, the clamping plate and the metal frame on this side will continue to push the photovoltaic panel to move, so that the photovoltaic panel slides between the third fixing block and the second fixing block, and finally the metal frames on both sides of the photovoltaic panel are installed; since the third fixing block and the second fixing block fix the photovoltaic panel through the limit spring, it is elastically fixed and not fixed, so the photovoltaic panel can slide, and finally the metal frame can be automatically installed without manual alignment of the photovoltaic panel, and it is suitable for photovoltaic panels of various sizes.

[0027] (2) The present invention realizes rapid laser cutting of the redundant parts of the metal frame through the structural design of the laser head control mechanism, without the need for customized processing of the metal frame in advance, avoiding quality problems such as gaps and extrusion during installation caused by dimensional inconsistency of the metal frame after processing, and is convenient for cutting photovoltaic panels of different sizes without the need for complicated operations, and has strong applicability; specifically, while the third fixing block and the second fixing block fix the photovoltaic panel, since the laser head control mechanism is installed on the top of the third fixing block and the second fixing block, the laser head of the laser head control mechanism can automatically align with the two sides of the photovoltaic panel, thereby eliminating the need for additional alignment operations on the laser head; the laser and the first forward and reverse motor are started, and the two sliders and the laser head are brought close to each other through the rotation of the first bidirectional screw. ; The laser heads cut the two ends and part of the bottom edge of the metal frame in the process of approaching each other, and cut off the ends of the metal frame; then the photovoltaic panel is switched to install the metal frames on the other two sides, and cutting is continued after installation. At this time, due to the thickness d of the installed metal frame itself, the third fixing block and the second fixing block automatically increase the distance when switching sides to fix the photovoltaic panel, so that the two laser head control mechanisms can be automatically adjusted, and then the adjustment screw is fine-tuned to make the adjustment block slide in the corresponding adjustment groove, and finally the distance between the two laser head control mechanisms is quickly adjusted, so as to facilitate the cutting of the excess parts of the other two metal frames, without the need for customized processing of the metal frame in advance, and at the same time, it is convenient for cutting photovoltaic panels of different sizes, without complicated operations, and has strong applicability.

[0047] Furthermore, L-shaped sliding blocks 453 are fixedly provided at both ends of the bottom of the third fixed block 450, and the two L-shaped sliding blocks 453 are clamped on both sides of the fixed plate 410 and are slidably connected to the fixed plate 410; a sliding rod 460 is fixedly connected to one side of the third fixed block 450, and a sliding hole 421 is opened in the first fixed block 420, and the sliding rod 460 is slidably connected to the sliding hole 421; a protrusion 470 is fixedly provided at one end of the sliding rod away from the third fixed block 450, and a limit spring 480 is sleeved on the sliding rod 460 located between the protrusion 470 and the first fixed block 420;

[0048] The laser head control mechanism 300 is fixedly mounted on the top of the second fixing block 440 and the third fixing block 450 .

[0049] Through the structural design of the fixing mechanism 400 of the present invention, when the photovoltaic panel 600 needs to be placed, the protrusion 470 is pulled, so that the sliding rod 460 pulls the third fixing block 450 to slide along the fixing plate 410, so that the distance between the third fixing block 450 and the second fixing block 440 is increased, thereby being suitable for photovoltaic panels 600 of different sizes; then the protrusion 470 is released, and the photovoltaic panel 600 is fixed under the reset limit of the limit spring 480. In this process, the third fixing block 450 and the second fixing block 440 will automatically adjust the angle of the photovoltaic panel 600, so that manual alignment is not required, thereby improving installation efficiency.

[0050] Furthermore, the laser head control mechanism 300 includes a support rod 360, and the tops of the second fixing block 440 and the third fixing block 450 are both fixedly installed with the support rod 360; the upper end of the support rod 360 is fixedly connected with a slide slot 310, and a first bidirectional screw rod 320 is arranged in the slide slot 310; both ends of the first bidirectional screw rod 320 are rotatably connected with both sides of the slide slot 310; a first forward and reverse motor 330 is fixedly installed outside one side of the slide slot 310, and the output shaft of the first forward and reverse motor 330 passes through the slide slot 310 and is fixedly connected with one end of the first bidirectional screw rod 320;

[0051] Two sliders 340 are symmetrically arranged on the first bidirectional screw rod 320, and a threaded opening 341 is opened on the slider 340. The threaded opening 341 of the slider 340 is threadedly connected to the first bidirectional screw rod 320, and the slider 340 is slidably connected to the slide groove 310; the slider 340 is fixedly connected to the laser head 350, and the output end of the laser head 350 is vertically downward.

[0052] It is worth noting that the laser head 350 of the present invention is equipped with a corresponding laser body. The laser light generated by the laser is transmitted to the laser head 350 at the speed of light, so that the laser head 350 focuses and guides the light beam to cut the object. At the same time, the cutting distance of the laser is adjustable. This is a prior art. The laser body is not drawn in the figure and will not be described in detail here.

[0053] Furthermore, the clamping mechanism 500 includes a second bidirectional screw rod 510, and rotating holes 140 are opened on both sides of the box body 100, and the two ends of the second bidirectional screw rod 510 are rotatably connected to the corresponding rotating holes 140 respectively; a second forward and reverse motor 520 is fixedly installed on the outer wall of the box body 100, and the output end of the second forward and reverse motor 520 is fixedly connected to one end of the second bidirectional screw rod 510; two clamping frames 530 are symmetrically screwed on the second bidirectional screw rod 510.

[0054] It is worth noting that the first forward and reverse motor 330, the second forward and reverse motor 520 and the laser head 350 of the laser of the present invention are all controlled by an external power supply, which will not be described in detail herein.

[0056] Four support blocks 430 are symmetrically fixedly connected on both sides of the fixed plate 410. The support blocks 430 are provided with limit slots 431. The limit bars 533 are located in the corresponding limit slots 431 and are slidably connected to the limit slots 431. A metal frame 700 is placed on the support blocks 430.

[0057] After fixing the photovoltaic panel 600, the present invention places the two metal frames 700 on the corresponding support blocks 430 after being coated with glue, and then starts the second forward and reverse motor 520, and the limiting strip 533 of the clamping frame 530 slides along the limiting slide groove 431 through the rotation of the second bidirectional screw rod 510; at this time, the two clamping frames 530 are close to each other so that the two clamping plates 532 push the metal frame 700, and under the clamping of the clamping plates 532, the metal frame 700 is inserted into the bottom edge 610 of the photovoltaic panel 600 to realize the installation of the metal frame 700; in the process of clamping the clamping plates 532, the position of the photovoltaic panel 600 is also automatically adjusted. If the clamping plates 532 on one side and the metal frame 7 00 contacts the photovoltaic panel 600 first instead of contacting them at the same time, then the clamping plate 532 and the metal frame 700 on this side will continue to push the photovoltaic panel 600 to move, so that the photovoltaic panel 600 slides between the third fixing block 450 and the second fixing block 440, and finally the metal frames 700 on both sides of the photovoltaic panel 600 are installed; because the third fixing block 450 and the second fixing block 440 fix the photovoltaic panel 600 through the limit spring 480, it is elastically fixed and not fixed, so the photovoltaic panel 600 can slide, and finally the metal frame 700 can be automatically installed without manual alignment of the photovoltaic panel 600, and it is suitable for photovoltaic panels 600 of various sizes.

[0058] Furthermore, the metal frame 700 is a C-shaped groove structure, and the depth of the metal frame 700 is not greater than the width of the bottom edge 610 .

[0059] Furthermore, the bottom of the support rod 360 is fixedly connected with an adjustment block 370; the top of the second fixing block 440 is provided with a first adjustment slot 441, and the top of the third fixing block 450 is provided with a second adjustment slot 451; the first adjustment slot 441 and the second adjustment slot 451 are slidably connected with the corresponding adjustment block 370;

[0060] The side wall of the first adjustment slot 441 is provided with a first adjustment hole 442, and the side wall of the second adjustment slot 451 is provided with a second adjustment hole 452; the adjustment block 370 is provided with an adjustment screw hole 371, and the adjustment screw 380 is screwed on the adjustment screw hole 371; the first adjustment hole 442 and the second adjustment hole 452 are rotatably connected with the corresponding adjustment screw 380. The adjustment screw 380 is rotated on the corresponding adjustment hole 452 to control the adjustment block 370 to slide on the corresponding adjustment slot, thereby adjusting the distance; the adjustment screw 380 can be rotated on the adjustment hole 452 by means of a limit groove, etc., which is a conventional setting and is not further limited.

[0061] The present invention realizes rapid laser removal of redundant parts of the metal frame 700 through the structural design of the laser head control mechanism 300, without the need for customized processing of the metal frame 700 in advance, avoiding quality problems such as gaps and extrusion during installation caused by size mismatch of the metal frame 700 after processing, and is convenient for cutting photovoltaic panels 600 of different sizes without complicated operations, and has strong applicability; specifically, while the third fixing block 450 and the second fixing block 440 fix the photovoltaic panel 600, since the laser head control mechanism 300 is installed on the top of the third fixing block 450 and the second fixing block 440, the laser head 350 of the laser head control mechanism 300 can automatically align with both sides of the photovoltaic panel 600, thereby eliminating the need for additional alignment operations on the laser head 350; start the laser and the first forward and reverse motor 330, and rotate the first bidirectional screw 320 to align the two sliders 340 and the laser head 350 with each other. Get close; the laser head 350 cuts both ends of the metal frame 700 and part of the bottom edge 610 in the process of getting close to each other, and cuts off the end of the metal frame 700; then the photovoltaic panel 600 is switched to install the metal frames 700 on the other two sides, and cutting is continued after installation. At this time, due to the thickness d of the installed metal frame 700 itself, the third fixing block 450 and the second fixing block 440 automatically increase the distance when switching sides to fix the photovoltaic panel 600, so that the two laser head control mechanisms 300 can be automatically adjusted, and then the adjustment screw 380 is fine-tuned to make the adjustment block 370 slide in the corresponding adjustment groove, and finally the distance between the two laser head control mechanisms 300 is quickly adjusted, so as to facilitate the cutting of the excess parts of the other two metal frames 700, without the need for customized processing of the metal frame 700 in advance, and at the same time, it is convenient for cutting photovoltaic panels 600 of different sizes, without the need for complicated operations, and has strong applicability. Fig.11 The following figure shows the finished product after installation and cutting. Fig.11 The upper and lower metal frames 700 are installed for the first time, and the left and right metal frames 700 are installed later. The length of the metal frames 700 installed later is greater than the metal frames 700 installed for the first time.

[0062] It is worth mentioning that when the metal frames 700 on both sides are installed for the first time and cutting is performed, the laser head 350 of the laser head control mechanism 300 can automatically align with the two sides of the photovoltaic panel 600 on the premise that the sizes of the laser head control mechanism 300 and the laser head 350 are set in advance; because the laser head control mechanism 300 is fixedly installed on the top of the corresponding fixed block, therefore, as long as the third fixed block 450 and the second fixed block 440 are fixed, the laser head 350 of the laser head control mechanism 300 can automatically align with the two sides of the photovoltaic panel 600; as for the sizes of the laser head control mechanism 300 and the laser head 350, they can be conventionally selected according to actual conditions and are not described in detail here.

[0063] Furthermore, a plurality of fixed suction cups 130 are fixedly provided at the bottom of the box body 100, and a cleaning door 120 and a switch panel 800 are installed on the side wall of the box body 100; a mounting plate 210 is fixedly connected to the upper end of the bracket 200, and mounting screw holes 220 are opened on the mounting plate 210, and the mounting screw holes 220 of the mounting plate 210 are fixed to the bottom of the fixing plate 410 through fixing screws.

[0064] The suction cup 130 can better fix the box 100, and the cleaning door 120 can regularly clean the scraps of the metal frame 700 accumulated after cutting inside the box 100, so as to facilitate recycling; the switch panel 800 is electrically connected to the first forward and reverse motor 330, the second forward and reverse motor 520 and electrical equipment such as the laser, so as to facilitate control; the structural design of the mounting plate 210 and the mounting screw hole 220 facilitates the rapid dismantling of the equipment and facilitates subsequent maintenance.

[0065] A method for cutting using the above-mentioned photovoltaic panel processing laser cutting equipment comprises the following steps:

[0066] S1, pull the protrusion 470 to place the photovoltaic panel 600 on the placement plate 401, then release the protrusion 470 to make the third fixing block 450 slide and cooperate with the second fixing block 440 to fix the photovoltaic panel 600;

[0067] S2, after the two metal frames 700 are coated with glue, they are placed on the corresponding support blocks 430, and then the second forward and reverse motor 520 is started, and the limiting strip 533 of the clamping frame 530 is made to slide along the limiting slide groove 431 through the rotation of the second bidirectional screw rod 510; at this time, the two clamping frames 530 are close to each other so that the two clamping plates 532 push the metal frame 700, and under the clamping of the clamping plates 532, the metal frame 700 is inserted into the bottom edge 610 of the photovoltaic panel 600; after the metal frame 700 is installed, the operation of the second forward and reverse motor is stopped;

[0068] S3, start the laser and the first forward and reverse motor 330, and make the two sliders 340 and the laser head 350 approach each other through the rotation of the first bidirectional screw 320; the laser head 350 cuts the two ends of the metal frame 700 and part of the bottom edge 610 in the process of approaching each other, and stops the machine after the end of the metal frame 700 is cut off, and the cut part is thrown into the box body 100;

[0069] S4, start the second forward and reverse motor 520 to reverse, so that the two clamping frames 530 release the clamping of the photovoltaic panel 600, then pull the protrusion 470, rotate the photovoltaic panel 600 90° and continue to place it on the placement plate 401, loosen the protrusion 470 to fix the photovoltaic panel 600 together with the third fixing block 450 and the second fixing block 440; continue steps S2 to S3, fine-tune the distance between the two laser head control mechanisms 300 by adjusting the screw 380, so that the laser cutting no longer cuts the bottom edge 610, and completes the cutting after cutting off the end of the metal frame 700.

[0070] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
