[0029] Example:

[0030] Reference Figure 1-5 , an anti-static rack for crystalline silicon battery production equipment, comprising a rack body 1 and a plurality of side panels 2 arranged around the rack body 1, and also comprising:

[0031] The ion ventilation component 3 includes a housing arranged on the side plate 2, a high voltage generator 301 arranged on the lower side of the housing, an induction steel ring 303 arranged on the upper side of the housing, and a fan 305 and a discharge needle 306 arranged on both sides of the middle of the induction steel ring 303;

[0032] The multi-stage flow diverter seat 4 includes a flow box 401 which is connected to the ion ventilation assembly 3 and a plurality of flow diverter valves 402 which are arranged outside the flow box 401;

[0033] The ion ventilation plate 5 includes a ventilation cover 302 arranged on one side of the frame body 1;

[0034] The electrostatic absorption component 6 includes a conductive roller 602 rotatably arranged on the other side of the frame body 1 and an indicator light 7 arranged at the bottom of the frame body 1 and connected to the conductive roller 602 .

[0035] The rack body 1 in this embodiment is an installation rack body for crystalline silicon battery production equipment, and there are many production equipment used in the production line of crystalline silicon batteries. By setting the anti-static structure on the rack body 1, it can be widely used in different equipment rack bodies on the crystalline silicon battery production line. The ion ventilation plate 5 and the electrostatic absorption component 6 can be respectively set at the equipment battery input or battery output port. The output ion gas in the ion ventilation plate 5 contacts the battery, and the conductive roller 602 on the static elimination component contacts the outer surface of the battery to achieve anti-static treatment of the processed battery. It is worth mentioning that through the setting of multiple vents on the multi-stage shunt seat 4, it is convenient for multiple external ion ventilation plates 5 to be connected to the multi-stage shunt seat 4, so as to achieve ion gas static elimination work at different positions of multiple rack bodies, increase the anti-static area of ​​the rack body, and improve the efficiency of the anti-static work of the rack body.

[0036] Reference Figure 2, an anti-static rack for crystalline silicon battery production equipment, further, a ventilation hood 302 connected to the casing is set between the induction steel ring 303 and the fan 305, and a negative electrode line 304 connected to the high voltage generator 301 is set at the lower end of the induction steel ring 303.

[0037] Before the high-voltage generator 301 is used, the positive electrode of the high-voltage generator 301 is connected to the discharge needle 306 through the positive wire 307, and the negative electrode is connected to the induction steel ring 303 through the negative wire 304. When in use, the high-voltage generator 301 is powered on and the existing electrical circuit flow technology is applied to form a loop between the high-voltage generator 301, the induction steel ring 303 and the discharge needle 306, providing conditions for the operation of the ion ventilation component 2. The wind hood is used to connect the outside with the inside of the casing, so that the fan 305 can draw external air into the casing when it is working, and the circuits of the high-voltage generator 301 are used simultaneously to add positive and negative ions to the drawn air.

[0038] Reference Figure 3 , an anti-static rack for crystalline silicon battery production equipment, further, the number of discharge needles 306 is several groups, one side of the several groups of discharge needles 306 is provided with the same blade, and the bottom of the blade is provided with a positive line 307 connected to the high voltage generator 301.

[0039] It is worth noting that when the high-voltage generator 301 is in use, the external power supply is input so that the electric energy is energized from the positive line 307 and the blades, and the blades direct the electric energy to the discharge needle 306. The tip of the discharge needle 306 discharges, and the negative line 304 of the high-voltage generator 301 is energized and connected with the induction steel ring 303. The discharge needle 306 reacts with the induction steel ring 303 to produce a large number of ions, which are then blown to the outside by the fan 305 through the ion ventilation plate 5, and the purpose of eliminating static electricity is achieved by combining with the positive and negative ions in the external environment and the battery.

[0040] Reference Figure 1 and Figure 3 , an anti-static rack for crystalline silicon battery production equipment, further, a same delivery pipe 403 is provided between the diverter valve 402 and the ion ventilation plate 5.

[0041] When the ion ventilation component 2 is working, the ion air in the multi-stage diverter seat can be respectively input into the separation valves at different positions. The opening of the diverter valve 402 can transport the gas in the multi-stage diverter seat to the ion ventilation plate 5, thereby realizing the static electricity removal of the gas. Among them, the diverter valve 402 uses the switching technology of the existing valve to control the switching state of the delivery pipe 403, thereby realizing the delivery of the gas in the multi-stage diverter seat.

[0042] Reference Figure 1, an anti-static rack for crystalline silicon battery production equipment. Furthermore, an air supply slot 501 is opened on the top of the ventilation hood 302, and the opening end of the air supply slot 501 is opened upward, which is convenient for aligning the ventilation hood 302 with the rack body, increasing the integrity between the rack body 1 and the ion ventilation plate 5, and facilitating the removal of the battery on the top of the rack body.

Furthermore, the electrostatic absorption component 6 includes a rotating seat 601 arranged on the rack body 1 and matched with the conductive roller 602, and a plurality of supporting springs 603 and conductive springs 604 arranged in the middle of the rotating seat 601.

[0044] It is worth noting that the electrostatic absorption components 6 are all made of metal materials. When the battery is transported from one end of the electrostatic absorption component 6 to the frame body 1, the electrons on the battery surface can be transferred to the conductive roller 602 through the contact between the battery side and the conductive roller 602, and the conductive roller 602 is rotated on the frame body 1 through the rotating seat 601, which can reduce the friction between the battery and the electrostatic absorption component 6 and improve the convenience of battery transportation. When the battery contacts the conductive roller 602, the support spring 603 and the conductive spring 604 in the rotating seat 601 are squeezed, and the elastic expansion and contraction characteristics of the spring are applied, so that the reset spring will push the battery upward, and then it can slide onto the frame body 1, thereby increasing the input rate of the battery.

[0045] Reference Figure 1 and Figure 4 , an anti-static rack for crystalline silicon battery production equipment, further, a connecting wire 701 is arranged between the indicator light 7 and the electrostatic absorption component 6, a grounding wire 702 is arranged at the bottom of the indicator light 7, the indicator light 7 is an existing LED light emitting diode, and the indicator light 7 applies the existing static elimination rod de-static indication technology, so that the indicator light 7 can illuminate the ions transported on the connecting wire 701, and through the setting of the grounding wire 702 at the bottom of the indicator light 7, the grounding wire 702 can conduct the ions absorbed by the electrostatic absorption component 6 to the ground, realize the discharge work, and continuously eliminate the static electricity of the battery.

[0046] Specifically, when the utility model is in use, multiple groups of electrostatic absorption components 6 and ion ventilation plates 5 can be set on the frame body 1 according to the number and area of ​​equipment in the crystalline silicon battery production line. By using multiple groups of electrostatic absorption components 6 and ion ventilation plates 5 at the input and output ends of the frame body 1, the outer surface of the input or output battery can be timely absorbed and neutralized, which increases the flexibility of static electricity elimination of the frame body, expands the static electricity removal area of ​​the frame body, and improves the static electricity removal rate of the battery. It has the advantages of simple structure, strong practicality, and low use cost, and solves the problems existing in the existing anti-static frame body.
