Description

Technical Field

[0001] The utility model relates to the field of photovoltaic frame production, in particular to a device for self-weight turning and bottom flexible landing. Background Art

[0002] At present, the aluminum alloy photovoltaic frame manufacturing industry is becoming more and more advanced and intelligent, and logistics and transportation are mostly automated. One of the links is to turn the aluminum alloy photovoltaic frame D side 404 downward and B side 402 upward (see Figure 3 ) to a state with D surface 404 facing upward and B surface 402 facing downward to meet production needs. One implementation method is to lift the material and then rely on gravity to flip it during the fall to complete the state transition. The disadvantage of this method is that the landing is hard. Although the conveyor belt is made of relatively soft material, the frequent impact from the falling frame can easily harden, damage, and age the material. The reaction force can also easily cause specific scratches and deformation of the aluminum alloy photovoltaic frame. Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a device for turning over materials by their own weight and for flexible landing at the bottom.

[0004] According to the utility model, a device for flipping materials by their own weight and landing flexibly at the bottom is provided, comprising: a lifting and conveying mechanism, an output conveying mechanism, an air collecting hood and an air blowing device, wherein the belt II of the lifting and conveying mechanism is mounted on a bracket III and a bracket IV which is higher than the bracket III, the air collecting hood is formed as a channel structure which passes through in the vertical direction and is mounted on the bracket IV in a cantilevered manner above the belt III of the output conveying mechanism, and the air blowing device comprises an air nozzle which supplies air to the air collecting hood from the bottom of the air collecting hood.

[0005] Preferably, the device for turning over the material by its own weight and landing flexibly at the bottom further comprises a feeding and conveying mechanism for conveying the work material to the lifting and conveying mechanism, and the work material is a photovoltaic frame profile.

[0006] Preferably, a plurality of feeding conveying mechanisms, lifting conveying mechanisms and output conveying mechanisms are arranged spaced apart in the longitudinal direction of the photovoltaic frame profile to be transported, wherein the lifting conveying mechanism and the downstream adjacent output conveying mechanism are staggered in the feeding direction.

[0007] Preferably, an air duct connected to the air nozzle is arranged between adjacent output conveying mechanisms.

[0008] Preferably, the feeding conveyor mechanism and the downstream adjacent lifting conveyor mechanism are arranged to be staggered in the feeding direction.

[0009] Preferably, the wind collecting cover includes two side panels facing each other and two vertical panels facing each other, and a plurality of air nozzles are arranged at intervals along a vertical line in the center of the two side panels.

[0010] Preferably, the plurality of air nozzles are arranged at equal intervals to blow air vertically upwards.

[0011] Preferably, each air nozzle is a circular air nozzle with the same size.

[0012] The beneficial effects of the present invention are as follows: during the falling process, the frame profile is lifted and buffered by the wind, which slows down the falling speed of the profile. The use of the wind gathering hood can make the wind more concentrated and the upward force greater, while saving kinetic energy and reducing costs, making the terminal speed of the frame profile extremely slow, thereby achieving the purpose of soft landing.

Unless otherwise specifically stated, the order of components and assembly steps and numerical values set forth in the embodiments do not limit the scope of the present invention.

[0018] According to an exemplary embodiment of the present invention, a device for self-weight turning and bottom flexible landing is provided. Figure 1 As shown, it includes: a feeding conveying mechanism 100, a lifting conveying mechanism 200, an output conveying mechanism 300, a wind collecting cover 500, and a blowing device 600. Figure 2 As shown, the photovoltaic frame profile 400 is placed on the feeding conveyor mechanism 100, handed over to the obliquely rising lifting conveyor mechanism 200 downstream, and flipped from its top side to the output conveyor mechanism 300 located below. During the continued falling process after flipping, the photovoltaic frame profile 400 passes through the inside of the wind collecting hood 500 and is subjected to the buffering force formed by the upward air supply of the blowing device 600, and finally achieves a flexible landing on the output conveyor mechanism 300.

[0019] Here, it is preferred to arrange multiple groups of feeding conveying mechanisms 100, lifting conveying mechanisms 200, and output conveying mechanisms 300 that are arranged overlapping with each other at intervals. Figure 2 It shows three feeding conveying mechanisms 100, four lifting conveying mechanisms 200, and three output conveying mechanisms 300 arranged longitudinally apart along the photovoltaic frame profile 400 to be transported, wherein the feeding conveying mechanism 100 can be staggered in the feeding direction with the downstream adjacent lifting conveying mechanism 200, and the lifting conveying mechanism 200 can be staggered in the feeding direction with the downstream adjacent output conveying mechanism 300.

[0020] The feeding and conveying mechanism 100 includes: a bracket I 101 , a support shaft I 102 , a roller I 103 , a belt I 104 , a roller II 105 , a support shaft II 106 , and a bracket II 107 .

[0021] In some embodiments, belt I 104 is supported by rollers I 103 and II 105 on either side. Support shafts I 102 and II 106 are located on either side of rollers I 103 and II 105. Support shafts I 102 and II 106 are secured within the top grooves of brackets I 101 and II 107, respectively. The left and right brackets I 101 and II 107 are at the same height, and the upper and lower surfaces of belt I 104 are parallel and parallel to the horizontal plane.

[0022] The lifting and conveying mechanism 200 comprises a bracket III 201, a support shaft III 202, roller III 203, a belt II 204, a support shaft IV 205, roller IV 206, and a bracket IV 207. Belt II 204 is supported by rollers III 203 and IV 206 on either side. The upper and lower surfaces of belt II 204 are parallel and angled with the horizontal plane. Rollers III 203 and IV 206 are flanked by support shafts III 202 and IV 205, respectively. These shafts are secured within the top grooves of brackets III 201 and IV 207, respectively.

[0023] In some embodiments, the left side support IV 207 is higher than the right side support III 201, causing the belt II 204 to form a certain angle with the horizontal plane. For example, the left side support IV 207 of the lifting conveyor mechanism 200 is 400 (±1) mm higher than the right side support III 201, and the center distance between the left and right sides is 692.8 (±0.2), so the angle between the belt II 204 and the horizontal plane is approximately 30 (±0.5) degrees.

[0024] The output transmission mechanism 300 includes: bracket V301, support shaft V302, roller V303, belt III304, roller VI305, support shaft VI306, and bracket VI307. Belt III304 is supported by rollers V303 and VI305 on either side, respectively. Support shafts V302 and VI306 flank rollers V303 and VI305, respectively. Support shafts V302 and VI306 are secured within the top grooves of brackets V301 and VI307, respectively. The left and right brackets V301 and VI307 are at the same height, and the upper and lower surfaces of belt III304 are parallel and horizontal.

[0025] The belt running speed of the feeding conveyor mechanism 100 and the lifting conveyor mechanism 200 is 200 mm / s, and the belt running speed of the output conveyor mechanism 300 is 220 mm / s. The speed difference between the upstream and downstream can prevent the subsequent incoming photovoltaic frames from hitting the previous photovoltaic frames.

[0026] The photovoltaic frame profile 400 includes an A surface 401, a B surface 402, a C surface 403, and a D surface 404 that constitute the profile.

[0027] The wind collecting cover 500 includes side panels 501 and vertical panels 502 , which are welded to the bracket IV 207 via a connecting block 503 to fix the wind collecting cover 500 .

[0028] In some embodiments, the main body of the wind concentrator 500 is composed of two vertical panels 502 and two side panels 501, forming a vertically continuous channel structure with a total of four circumferential surfaces, without a bottom surface or a top surface. The cross-sectional length of the wind concentrator 500 should be longer than the length of the photovoltaic frame profile 400 to ensure that the photovoltaic frame profile 400 can pass through and fall into the wind concentrator 500 without interference. The width of the wind concentrator 500 should be moderate, and preferably, the center of the side panels 501 is aligned with the air nozzles 601 below, so that each air nozzle 601 is neatly aligned with the center of the cross-sectional area of the wind concentrator 500 along a line.

[0029] In some embodiments, the air collecting hood 500 is made of 304 stainless steel, with a steel plate thickness of 2.5 (±0.2) mm, a length greater than the maximum predetermined length of the aluminum alloy profile of 400 (±5) mm, a width of 550 (±2) mm, and a height of 550 (±5) mm.

[0030] In some embodiments, the wind concentrator 500 is connected to the upper left portion of the support IV 207 and cantilevered above the belt III 304 to allow the photovoltaic frame profile 400 to pass through and fall onto the belt III 304. The wind concentrator 500 is welded to the support IV 207 with a connecting block 503 located 250 (±2) mm below the roller IV 206, effectively concentrating the wind. The connecting block 503 is made of 304 stainless steel and has specifications of 60 (±0.03) mm in length, 60 (±0.03) mm in width, and 30 (±0.03) mm in height.

[0031] The blowing device 600 includes an air nozzle 601 and an air duct 602 .

[0032] like Figure 2 As shown, the belt of the feeding conveyor mechanism 100 and the belt of the output conveyor mechanism 300, which are opposite to each other in the feeding direction, are arranged to be located on the same straight line, and the belt of the lifting conveyor mechanism 200 is arranged to be spaced apart in the transverse direction. The air duct 602 is arranged in such a way that the air nozzle 601 is located between adjacent output conveyor mechanisms 300, and is preferably aligned on the same straight line with the belt of the lifting conveyor mechanism 200.

[0033] In some embodiments, four equally spaced air nozzles 601 are installed beneath the air concentrator 500. These nozzles 601 and the center of the side panels 501 of the air concentrator 500 are aligned on a vertical line (an imaginary line perpendicular to the side panels 501) and connected to the air duct 602. The air nozzles 601 are circular (having a larger blowing area than flat nozzles) and are all of uniform size to ensure consistent blowing effects. The nozzles 601 should be installed on the same straight line, with the four nozzles 601 spaced evenly apart. The air duct 602 is made of 304 stainless steel, with an inner diameter of 50 (±0.03) mm and a wall thickness of 2.5 (±0.02) mm. The nozzles 601 are perpendicular to the air duct 602, with an inner diameter of 50 (±0.03) mm and a wall thickness of 2.5 (±0.02) mm. The air pressure of the nozzles 601 is 1.5-2 MPa, and the air speed is 7-10 m / s.

[0034] When the photovoltaic frame profile 400 reaches the highest point of the lifting stage 400 (B), due to its own gravity, the photovoltaic frame profile 400 will have a flipping process from D side 404 facing downward to D side 404 facing upward. This process is completed during the descent process (common production knowledge, not described in detail). Due to the upward support force of the wind nozzle 601 (especially with the addition of the wind gathering cover 500), the descent speed will be slowed down by 70-85% to achieve the purpose of flexible landing.

[0035] As the photovoltaic frame profile 400 is conveyed from right to left along the belt I 104 of the feeding conveyor mechanism 100, the photovoltaic frame profile 400 is now in feeding phase 400 (A), with surface D 404 facing downward and surface B 402 facing upward. At the junction of the feeding conveyor mechanism 100 and the lifting conveyor mechanism 200, the photovoltaic frame profile 400 is lifted by the belt II 204 of the lifting conveyor mechanism 200, and now is in lifting phase 400 (B), with surface D 404 facing downward and surface B 402 facing upward. Upon reaching the highest point, the photovoltaic frame profile 400, affected by its initial velocity and gravity, reverses its downward trajectory. By properly configuring the falling distance, the material's state change can be achieved, and the photovoltaic frame profile 400 now lands on the belt III 304 of the output conveyor mechanism 300, with surface D 404 facing upward and surface B 402 facing downward. The photovoltaic frame profile 400 is now in output phase 400 (C).

[0036] In this way, according to the present invention, the following beneficial effects can be achieved: when the photovoltaic frame profile 400 passes through the wind collecting cover 500 and falls, the upward force of the wind will slow down the falling speed of the profile. The use of the wind collecting cover 500 can make the wind more concentrated and the upward force greater, while saving kinetic energy and reducing costs, making the terminal speed of the profile extremely slow, and achieving the purpose of soft landing.
