Description

Technical Field

[0001] The invention relates to the technical field of battery cell flipping, and in particular to an anti-fouling and anti-debris battery cell flipping machine which uses wind power to flip the battery cell. Background Art

[0002] In the later process of manufacturing solar photovoltaic crystal cells, semi-finished products are turned over manually multiple times between processes, which directly increases the labor cost in product manufacturing and affects production efficiency. It is also easy to cause scratches, cracks and breakages on the products, thus affecting the appearance quality and internal performance. In severe cases, it can directly affect the service life of the products, causing economic losses to the company and affecting its brand.

[0003] In order to solve the above problems, the prior art generally adopts two flipping methods: suction cup type and clamping type. Application No. "201110460847.4" is a 180° automatic flipping machine for solar crystal cells. It flips the cells by using a suction cup to absorb the cells. The structure is as shown in the attached manual. Figure 1 As shown, the battery cell 100 is sucked up by the suction cup 30, and the battery cell 100 is turned 180° by the suction cup shaft 31. However, this method is prone to the operation error of the suction cup 30, which may cause the battery cell 100 to break. By using the clamping method to turn the battery cell, the structure is as shown in the attached manual. Figure 2 As shown, one end of the cell 100 is clamped by the clamping sleeve 40, and the cell 100 is turned 180 degrees by the clamping shaft 41. However, this clamping method is not only easy to cause pollution to the upper and lower surfaces and side wall surfaces of the cell 100, but also easy to crush and crack the cell. Both of the above methods may cause damage to the cell 100, which is becoming increasingly impractical for the manufacturing process of photovoltaic cells and will cause economic losses. Summary of the invention

[0004] The object of the present invention is to provide an anti-fouling and anti-debris battery cell flipping machine that uses wind power to flip the battery cell, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An anti-fouling and anti-debris battery cell flipping machine that uses wind power to flip, comprising two flipping platforms arranged at intervals, a semicircular arc sleeve movably arranged between the flipping platforms, a central rotating shaft fixedly inserted in the middle of the semicircular arc sleeve, one end of the central rotating shaft is fixedly connected to a stepper motor through a coupling, the stepper motor is fixedly connected to the flipping platform, and the upper and lower sides of the central rotating shaft are symmetrically connected to wind control balancing mechanisms;

[0007] The wind control balancing mechanism includes a connecting rod, an air rod, an air nozzle and an air pump. The connecting rod is fixedly connected to the central rotating shaft. The air rod is vertically connected to the connecting rod. An air supply passage is opened in the air rod. A plurality of air outlets are connected to the air supply passage. The air nozzle is fixedly connected to one end of the air outlet away from the air supply passage. The air pump is fixedly connected to the side wall of the air rod. A single-chip microcomputer and a spirit level are also fixedly arranged on the air pump. The air pump and the spirit level are electrically connected to the single-chip microcomputer. The air pump is connected to the air supply passage through an air pipe.

[0008] Preferably, a buffer layer and a sterile layer are sequentially attached to the inner wall of the semicircular arc sleeve.

[0010] Preferably, a front conveyor belt and a rear conveyor belt are respectively provided on both sides of the turning platform.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention can control the battery cell in a state of being suspended up and down by arranging the air nozzles on both sides of the battery cell, so that the upper and lower surfaces of the battery cell will not be sucked and clamped, thereby avoiding contamination and hidden cracking. The semi-circular arc sleeve can be provided to provide the battery cell with a rotation base point during the flipping process, thereby preventing the upper and lower surfaces of the battery cell from contacting the semi-circular arc sleeve during the rotation process. Moreover, the semi-circular arc sleeve can also avoid contact with the side wall surface of the battery cell, thereby better protecting the battery cell from contamination or breakage.

[0013] The device of the present invention sets and controls the real-time air output of the upper and lower air nozzles during the 180° rotation process in advance based on the fact that the size and weight of each batch of qualified battery cells produced are the same, so as to ensure that the battery cells always remain in a suspended state during the flipping process and will not come into contact with or be squeezed by the upper and lower surfaces. The flipping of the battery cells is controlled by wind blowing, which will not cause contact with the battery cells and avoid pollution and debris. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-13, the present invention provides a technical solution:

[0030] A wind-powered anti-fouling and anti-debris cell flipping machine comprises two flipping platforms 1 arranged at intervals, the two flipping platforms 1 are arranged in parallel, and the interval distance ensures that both ends of the cell 100 can be placed on the flipping platform 1 when placed, and a front conveyor belt 22 and a rear conveyor belt 23 are respectively arranged on both sides of the flipping platform 1. The front conveyor belt 22 is used to transfer the cell 100 to be flipped, so that the cell 100 can be slowly transferred to the flipping platform 1, and the cell 100 can be directly plugged into the semi-automatic In the circular arc sleeve 2, a semi-circular arc sleeve 2 is movably arranged between the flip platforms 1, and the inner wall of the semi-circular arc sleeve 2 is sequentially affixed with a buffer layer 20 and a sterile layer 21. The buffer layer 20 can be made of materials such as sponge or rubber. In order to prevent the battery cell 100 from being damaged by collision with the inner wall of the semi-circular arc sleeve 2 when it is just inserted into the semi-circular arc sleeve 2, the sterile layer 21 can be laid and pasted with existing materials such as sterile paper to protect the battery cell 100 and prevent the battery cell 100 from being contaminated when it contacts the inner wall of the semi-circular arc sleeve 2.

[0031] A central rotating shaft 3 is fixedly inserted in the middle of the semicircular arc sleeve 2. The central rotating shaft 3 can drive the semicircular arc sleeve 2 to rotate 180°. One end of the central rotating shaft 3 is fixedly connected to a stepper motor 5 through a coupling 4. The stepper motor 5 is fixedly connected to the flip platform 1. The motor main shaft of the stepper motor 5 drives the central rotating shaft 3 to rotate through the transmission effect of the coupling 4. The stepper motor 5 uses the 21000 series SIZE8 rotary motor of Changzhou Wheeler Motor Co., Ltd. When the stepper driver receives a pulse signal, it drives the stepper motor 5 to rotate a fixed angle in the set direction, which is called " Step angle", its rotation is run step by step at a fixed angle, so as to control the stepping motor 5 to just drive the semicircular arc sleeve 2 to rotate 180°. The upper and lower sides of the central rotating shaft 3 are symmetrically connected with wind control balancing mechanisms. There are four groups of wind control balancing mechanisms. The central rotating shaft 3 is provided with two groups of wind control balancing mechanisms at both ends of the semicircular arc sleeve 2, which are symmetrically fixed on the upper and lower sides of the central rotating shaft 3 respectively. The two groups of wind control balancing mechanisms arranged on the lower side are controlled by an air pump 11 for output, and the two groups of wind control balancing mechanisms arranged on the upper side are controlled by another air pump 11.

[0032] The wind control balancing mechanism includes a connecting rod 6, an air rod 7, an air nozzle 10 and an air pump 11. The connecting rod 6 is fixedly connected to the central rotating shaft 3. The air rod 7 is vertically connected to the connecting rod 6. An air delivery channel 8 is opened in the air rod 7. The air delivery channel 8 is connected to a plurality of air outlets 9. The air nozzle 10 is fixedly connected to the end of the air outlet 9 away from the air delivery channel 8. The air pump 11 is fixedly connected to the side wall of the air rod 7. The air pump 11 controls and ejects air from the air nozzle 10 through the air pipe 14 and the air delivery channel 8 to provide a wind force for supporting the battery cell 100. The air pump 11 uses the AC micro AC-A piston air pump 11 of Chengdu Xinweicheng Technology Co., Ltd., and a single-chip microcomputer 12 and a level 13 are also fixedly arranged on the air pump 11. The level 13 uses the green light 12-line GLL3-80CG laser level of Shanghai Hemudu Industrial Development Co., Ltd., which can be realized The inclination angle of the gas rod 7 set horizontally in the initial state is detected, and the wind force to be outputted corresponding to the gas rod 7 with different inclination angles set in advance is used to control the output wind force of the air nozzles 10 on the upper and lower sides, so that the battery cell 100 always maintains a working state where it does not contact the inner wall of the semicircular arc sleeve 2 with a large area. The output wind force set in advance can be obtained and set through multiple experiments. The data is input into the single-chip microcomputer 12 in advance. For battery cells 100 of different sizes and weights, the output wind force of the air nozzles 10 with different inclination angles set in advance is different. The air pump 11 and the spirit level 13 are electrically connected to the single-chip microcomputer 12. The air pump 11 is connected to the air supply duct 8 through the air pipe 14. The air pump 11 is controlled through the I / O pin of the 80C51 single-chip microcomputer 12 to control the output power of the air pump 11, thereby controlling the wind force.

[0033] As a preferred embodiment, an upper groove 15 and a lower connecting groove 17 are respectively provided in the upper and lower directions of the inner wall of the semicircular arc sleeve 2. A laser 16 is fixedly arranged in the upper groove 15, and a light receiver 18 and a motor controller 19 are arranged in the lower connecting groove 17. The light receiver 18 and the stepper motor 5 are electrically connected to the motor controller 19. When the battery cell 100 is horizontally inserted into the semicircular arc sleeve 2 along the flip platform 1, the light receiver 18 cannot receive the laser signal output by the laser 16, and the motor controller 19 can automatically and intelligently control the stepper motor 5 to rotate. The combination of the laser 16 and the light receiver 18 uses the E18-5NA transmission type photoelectric switch of Yueqing Gaobai Electric Co., Ltd. The photoelectric switch includes a projector 16 and a light receiver 18. The light receiver 18 directly converts the optical signal into an electrical signal and transmits it to the motor controller 19. The motor controller 19 can use a simple PLC control or an 80C51 type single-chip microcomputer to directly transmit the signal to the stepper motor 5 to control it to rotate, thereby liberating the labor of the workers and achieving a better rotation effect.

[0034] Working principle: In the initial state, the battery cell 100 is inserted into the semicircular arc sleeve 2 along with the front conveyor belt 22, and then the air pump 11 on the lower side is turned on. The output wind force provided by the air pump 11 is exactly the same as the gravity of the battery cell 100, so that the battery cell 100 is suspended on the flip platform 1. At this time, the air pump 11 on the upper side does not provide wind force. Then, during the rotation process, the wind force output by the air pump 11 on the lower side is gradually reduced, so that the battery cell 100 always keeps away from contact with the upper air nozzle 10 and The air nozzle 10 on the lower side is in a suspended state, and one end of the battery cell 100 is attached to the inner wall of the semicircular sleeve 2. When the semicircular sleeve 2 rotates 90°, the air pump 11 on the lower side no longer provides wind force, and the air pump 11 on the upper side moves to the lower side of the battery cell 100 and continues to provide wind force that increases from small to the same as the gravity of the battery cell 100, thereby supporting the battery cell 100 until the battery cell 100 rotates to above the rear conveyor belt 23, so that the rear conveyor belt 23 can be transported.
