Description

Technical Field

[0001] The invention relates to the technical field of cell production, and in particular to a photovoltaic cell production feeding device. Background Art

[0002] Photovoltaic cells are the core components of solar power generation systems and are used to convert light energy into electrical energy. During the processing and production of photovoltaic cells, the cells need to be stacked and placed in a placement frame for loading so that the cells can be transported to the next step for processing.

[0003] The patent document with announcement number CN109305557B discloses a feeding device for battery cell production, including a fixed seat, a vertically arranged electric telescopic rod is bolted to the middle position of the top outer wall of the fixed seat, and a lifting block with a circular cross section is bolted to the top outer wall of the electric telescopic rod, a support seat is bolted to both sides of the top outer wall of the fixed seat, and a ventilation seat is bolted to the top outer wall of the support seat, and a ventilation hole is opened in the middle position of the top outer wall of the ventilation seat. A suction nozzle is provided on the vacuum suction cup, and the battery cell on the top is sucked and transported by the suction nozzle.

[0004] However, the solution still has the following problems. When loading battery cells, it is necessary to select the appropriate number of suction nozzles according to the shape and size of the battery cells, that is, battery cells of different specifications, so as to reduce the deformation of the battery cells during transportation and ensure the adsorption effect and processing accuracy. In the above-mentioned prior art, the number and arrangement of suction nozzles on the vacuum suction cup are fixed, and multiple suction nozzles are interconnected. When adsorbing battery cells, it is necessary to evacuate multiple suction nozzles at the same time so that the inside of the suction nozzles is in a negative pressure state. When loading battery cells of different specifications, it is inevitable that there are some suction nozzles that do not need to adsorb battery cells. However, in order to ensure that the inside of the remaining suction nozzles is in a negative pressure state, it is necessary to continue to evacuate, resulting in energy waste. It may even cause the air pressure inside the adsorbed suction nozzle to be unstable, causing the battery cells to fall off, making it inconvenient to load battery cells of different specifications. Summary of the invention

[0005] The present invention provides a photovoltaic cell production feeding device, aiming to solve the problem in the related art that when a suction nozzle does not adsorb a cell, continuous air extraction is required during the feeding process, making it inconvenient to feed cells of different specifications.

[0006] The photovoltaic cell production loading device of the present invention comprises a suction cup and a plurality of suction nozzles arranged on the suction cup, a cavity is opened in the suction cup, a through hole connected to the cavity is provided on the suction nozzle, when the cavity is in a negative pressure state, the suction nozzle adsorbs the cell, a sealing plate and a driving member are rotatably arranged in the suction nozzle, the driving member is connected to the sealing plate to drive the sealing plate to rotate, a control panel is slidably arranged on the suction cup toward the suction nozzle, a plurality of insertion rods are correspondingly arranged on the control panel and the plurality of suction nozzles, a plug hole is opened on the sealing plate, when there is continuous airflow in the suction nozzle under a negative pressure state of the cavity, the driving member drives the sealing plate to rotate to the through hole, after the sealing plate rotates to the through hole, the control panel is slid to drive the insertion rod to be inserted into the plug hole, the insertion rod and the plug hole are cooperated to fix the sealing plate, and the suction nozzle stops adsorption when the sealing plate is in the through hole.

[0007] The effect is that before loading, the battery cell is placed on the suction nozzle, and air is pumped to make the interior of the cavity in a negative pressure state. At the same time, the interior of the suction nozzle is also in a negative pressure state, and the battery cell is adsorbed by the suction nozzle. The suction nozzle that is not adsorbed on the battery cell will generate continuous airflow inside. At this time, the driving part drives the sealing plate to rotate to the through hole, and then moves the sealing plate to drive the insertion rod to move. The insertion rod moves to engage with the insertion hole to fix the sealing plate, and then the non-adsorbed suction nozzle is closed, so that the number of suction nozzles and the adsorption position are determined according to the specifications of the battery cell, and when different battery cells need to be replaced for loading, the above operation can be repeated, so that the battery cells of this specification can be stably transferred later, reducing the energy waste caused by continuous suction of the non-adsorbed suction nozzle, and at the same time ensuring the stability of the adsorbed suction nozzle, so as to load battery cells of different specifications.

[0008] Preferably, the driving member includes a rotating rod, blades and an elastic member. The rotating rod is rotatably arranged in the suction nozzle, and the blades are arranged on the side of the rotating rod. When the cavity is under negative pressure, airflow is formed in the suction nozzle, and the airflow passes through the blades to drive the blades to rotate. The end of the rotating rod and the sealing plate are arranged at an interval. The elastic member is arranged between the rotating rod and the sealing plate to connect the two. A top block is slidably arranged on the inner wall of the suction nozzle. When the top block is clamped in the socket, the through hole is in an open state. The rotation of the rotating rod drives the elastic member to twist and store force. When the blades continue to rotate, the top block is separated from the socket, and the elastic member drives the sealing plate to rotate to the through hole.

[0009] The effect is that when the suction nozzle does not adsorb the battery cell, a continuous airflow is generated inside the nozzle, and the airflow passes through the blades to drive the blades to rotate, and the rotation of the blades drives the rotating rod to rotate, and the rotation of the rotating rod drives the elastic member 1 to twist. After the twisting force of the elastic member 1 reaches a certain degree, it drives the top block to separate from the socket, and the sealing plate rotates to seal the through hole, so that the suction nozzle stops adsorbing. At the same time, the elastic member 1 is provided, and a short airflow is generated inside the nozzle when the suction nozzle adsorbs. At this time, the rotation amplitude of the rotating rod is not enough to drive the top block to separate from the socket, and the sealing plate is stationary, and the adsorbed suction nozzle will not be accidentally closed.

[0010] Preferably, a middle hole for inserting the insertion rod is opened through the suction nozzle, and the middle hole is arranged on one side of the through hole. The insertion rod is inserted into the socket through the middle hole. A positioning plate is arranged on the inner wall of the suction nozzle. When the sealing plate rotates to abut against the positioning plate, the socket rotates to the middle hole.

[0011] The effect is that when the sealing plate is rotated to close the through hole and the plug hole corresponds to the through hole, the sealing plate abuts against the positioning plate so that the insertion rod can be inserted into the plug hole through the middle hole to fix the sealing plate. When the same specification of battery cells are subsequently loaded, the corresponding suction nozzle remains in a fixed closed state under the action of the sealing plate, so that only the suction nozzle that needs to be adsorbed is evacuated, thereby improving the loading effect of the battery cells.

[0012] Preferably, a mounting rod is provided in the suction nozzle, the rotating rod and the sealing plate are both rotatably arranged outside the mounting rod, and a set of elastic parts is arranged outside the mounting rod.

[0013] The effect is that the rotating rod and the sealing plate are rotatably arranged outside the mounting rod, and the elastic member 1 is arranged outside the rotating rod, so that the sealing plate and the rotating rod can rotate stably in the suction nozzle, and it is also convenient to install the elastic member 1 between the sealing plate and the rotating rod and connect the two.

[0014] Preferably, when the sealing plate is rotated until its side abuts against the insertion rod, the through hole is in a closed state, a mounting block is provided on the mounting rod, a clamping block is slidably provided on the mounting block, a spring is provided in the mounting block, the spring is used to drive the clamping block to slide in a direction away from the mounting rod, a rotating sleeve is provided on the rotating rod, the rotating sleeve is provided on the outside of the clamping block, a clamping groove is provided on the inner wall of the rotating sleeve, and the clamping block and the clamping groove cooperate to fix the sealing plate.

[0015] The effect is that the spring drives the clamping block to slide toward the clamping slot, and the clamping block and the clamping slot are engaged to fix the rotating rod, and then fix the sealing plate.

[0016] Preferably, the mounting block is slidably arranged on the mounting rod along the vertical direction, a plurality of slots are circumferentially provided around the axis of the rotating rod, an adjusting piece for adjusting the position of the mounting block is provided on the suction nozzle, a slope is provided on one side of the block, and the rotating sleeve rotates the block to engage with different slots in sequence through the slope.

[0017] The effect is that when the battery cell is adsorbed, the adjustment member drives the mounting block to move into the rotating sleeve so that after the sealing plate rotates to seal the through hole, it is fixed and the corresponding non-adsorbed suction nozzle is closed to reduce its effect on the battery cell loading.

[0018] Preferably, a sliding frame is provided on the suction nozzle, and an opening is provided on a side of the sliding frame close to the cavity. The adjusting member includes a sliding plate and a connecting rod. A mounting groove is provided in the mounting rod, and a sliding groove is provided on the side of the mounting rod that is connected to the mounting groove. The mounting block is slidably arranged in the sliding groove, and the connecting rod is slidably arranged in the mounting groove. The connecting rod is connected to the mounting block, and one end of the connecting rod away from the mounting rod extends into the sliding frame. The sliding plate slides toward the direction of the cavity under the action of the negative pressure in the cavity, and the sliding of the sliding plate drives the mounting block to move to the rotating sleeve through the connecting rod.

[0019] The effect is that when the interior of the cavity is in a negative pressure state, the slide plate is driven to move toward the cavity, the movement of the slide plate drives the connecting rod to move, the movement of the connecting rod drives the mounting block to move, and the movement of the mounting block drives the clamping block to move into the rotating sleeve, so that the clamping block and the clamping groove are engaged to fix the sealing plate.

[0020] Preferably, a through pipe is provided on the slide frame, and the through pipe is provided on a side of the slide plate away from the cavity, and the through pipe is used to connect the interior of the slide frame with the outside.

[0021] The effect is that the through pipe is provided so that the side of the slide away from the cavity is at normal air pressure, so that the slide can move toward the cavity when the cavity is under negative pressure, and then the sealing plate is fixed by a rotating rod or the like.

[0022] Preferably, the outer sleeve of the connecting rod is provided with a second elastic member, which is respectively connected to the slide plate and the side wall of the suction nozzle, and is used to drive the slide plate to move in a direction away from the cavity.

[0023] The effect is that the second spring is provided so that after the loading is completed, the slide plate moves to the initial position under the action of the second spring, and at the same time the restriction on the sealing plate is released, and the sealing plate also rotates to the initial position so as to adsorb and load the battery cell again.

[0024] Preferably, a sensing member is provided on the positioning plate, a controller is provided on the suction cup, the sensing member is electrically connected to the controller, a pushing member for adjusting the position of the control plate is provided on the suction cup, the control end of the controller is electrically connected to the switch of the pushing member, the sensing member is used to detect the position of the sealing plate, and after the sensing member detects that the sealing plate is abutting against the positioning plate, the controller controls the pushing member to start adjusting the position of the control plate.

[0025] The effect is that after the sealing plate rotates to the positioning plate, the sensing element sends a signal to the controller. After receiving the signal, the controller controls the push element to start, and the push element starts to drive the control plate to move. The movement of the control plate drives the insertion rod to cooperate with the socket to fix the sealing plate.

[0026] Beneficial effects:

[0027] 1. By rotating the sealing plate set in the suction nozzle, the suction nozzle is first adsorbed on the battery cell of the specified specification before loading. The sealing plate in the suction nozzle that does not adsorb the battery cell rotates to the through hole, and the corresponding suction nozzle that is not adsorbed is closed. Then the control board is moved to drive the plug rod and the jack to cooperate to fix the sealing plate, thereby determining the number of suction nozzles required for the battery cell of this specification and the corresponding adsorption position. When loading the battery cell of this specification in the future, use the determined suction nozzle for adsorption loading. When it is necessary to replace the battery cell of different specifications, repeat the above operation to load the battery cells of different specifications.

[0028] 2. After the suction nozzle is determined to adsorb the battery cell, the sealing plate in the suction nozzle that is not adsorbed on the battery cell is rotated to the through hole, and the card block is engaged with the corresponding card slot to close the suction nozzle that is not adsorbed. At the same time, after the battery cell is loaded, the card block is separated from the card slot, the sealing plate is rotated to the initial position, and the suction nozzle is opened again to reduce the effect of affecting the loading of the battery cell due to the inability of some suction nozzles to adsorb the battery cell during the loading process.

[0040] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0041] like Figures 1 to 9 As shown, the photovoltaic cell production feeding device of the present invention comprises a suction cup 1, a suction nozzle 2 and a sealing plate 3. A plurality of suction nozzles 2 are evenly distributed on the suction cup 1. A cavity 11 is provided in the suction cup 1. The cavity 11 is connected to the inside of the suction nozzle 2. A through hole 21 connected to the cavity 11 is provided on the suction nozzle 2. The sealing plate 3 is rotatably arranged in the suction nozzle 2. The sealing plate 3 can be rotated to the through hole 21 to block the through hole 21. When feeding the cell, the suction cup 1 is moved to the cell, and the vacuum pump evacuates the cavity 11 so that the inside of the cavity 11 is in a negative pressure state. Under the action of the negative pressure cavity 11, the suction nozzle 2 adsorbs the cell, and at the same time, the sealing plate 3 inside the suction nozzle 2 that does not need to adsorb the cell rotates to close the through hole 21, so as to avoid the suction nozzle 2 that is not adsorbed from being in a state of constantly evacuating air, reduce energy waste, and improve the stability of the remaining suction nozzles 2 when adsorbing the cell, so as to feed the cell of different specifications.

[0042] Reference Figures 2 to 4The suction nozzle 2 includes a suction tube 24 and a suction head 25. The suction tube 24 is connected to the suction cup 1. The suction head 25 is arranged on the side of the suction tube 24 away from the suction cup 1, that is, the suction head 25 is connected to the cavity 11 through the suction tube 24. A mounting rod 7 is arranged in the suction nozzle 2. The mounting rod 7 is coaxially arranged with the suction tube 24. A driving member 4 is arranged in the suction nozzle 2. The driving member 4 includes a rotating rod 41, a blade 42 and an elastic member 43. The rotating rod 41 is rotatably arranged in the suction tube 24, and the rotating rod 41 is rotatably matched with the mounting rod 7. The rotating rod 41 is sleeved on the outside of the mounting rod 7. The blade 42 is arranged on the side of the rotating rod 41, and a plurality of blades 42 are arranged around the rotating rod 41. The blade 42 is arranged obliquely relative to the rotating rod 41, so that the airflow in the suction tube 24 can drive the blade 42 to rotate when passing through the blade 42. The sealing plate 3 is arranged to rotate outside the mounting rod 7. The sealing plate 3 and the rotating rod 41 are arranged at intervals. The elastic member 43 is arranged between the two. The elastic member 43 can be set as a torsion spring. The torsion spring is sleeved on the outside of the mounting rod 7, and the two ends of the torsion spring are respectively connected to the sealing plate 3 and the rotating rod 41. For battery cells of different specifications, when there is a suction nozzle 2 that does not absorb the battery cell, in order to ensure that the cavity 11 is in a negative pressure state, the cavity 11 is continuously evacuated to form an airflow in the suction tube 24. The airflow passes through the blade 42 to drive the rotating rod 41 to rotate. The rotating rod 41 rotates and drives the sealing plate 3 to rotate to the through hole 21, and the through hole 21 is blocked and closed, and the suction of the suction nozzle 2 is stopped.

[0043] Reference Figures 5 to 7 A top block 22 is arranged on the inner wall of the straw 24, and the top block 22 slides in the vertical direction. A spring is arranged in the inner wall of the straw 24, and the spring is connected to the top block 22 to drive the top block 22 to slide in the direction toward the sealing plate 3. The end of the top block 22 extending to the outside of the inner wall of the straw 24 is arranged in a spherical shape, and the spherical end of the top block 22 cooperates with the inner wall of the insertion hole 31. The sealing plate 3 rotates to press the top block 22 into the inner wall of the straw 24 through the spherical end of the top block 22, so that the top block 22 is separated from the insertion hole 31. In the initial state, the top block 22 is stuck in the insertion hole 31, and a short airflow is formed in the straw 24 when the suction nozzle 2 absorbs the battery cell. At this time, the rotating rod 41 rotates a certain angle, and the elastic member 43 is twisted briefly. After the suction nozzle 2 absorbs the battery cell, the rotating rod 41 rotates to the initial position. In this process, the top block 22 and the insertion hole 31 remain in a matching state, and the sealing plate 3 is fixed. When the battery cell is not adsorbed at the suction nozzle 2, a continuous airflow is formed inside the suction tube 24, thereby driving the rotating rod 41 to rotate continuously. After the rotating rod 41 drives the elastic member 43 to twist to a certain angle, the elastic member 43 is subjected to a certain force until the sealing plate 3 can rotate to press the top block 22 into the side wall of the suction tube 24 until the top block 22 is separated from the insertion hole 31. Under the action of the elastic member 43, the sealing plate 3 rotates to the through hole 21 to block the through hole 21, so that the corresponding suction nozzle 2 stops adsorption.

[0044] Reference Figures 1 to 3In order to facilitate the fixing of the sealing plate 3 that rotates to the through hole 21, a control board 5 is provided on the suction cup 1. The control board 5 is slidably arranged in the direction of the suction nozzle 2. A plug rod 51 is provided on the control board 5. A middle hole 23 is penetrated through the suction nozzle 2. The end of the plug rod 51 that is away from the control board 5 can move into the suction nozzle 2 through the middle hole 23. After the sealing plate 3 rotates to the through hole 21, the plug hole 31 rotates to correspond to the middle hole 23, and then the control board 5 is slid. The control board 5 drives the plug rod 51 to be inserted into the plug hole 31 to fix the sealing plate 3, so that the suction nozzle 2 remains in a closed state, and the stability of the other suction nozzles 2 is improved.

[0045] Reference Figures 1 to 3 , multiple insertion rods 51 and multiple suction nozzles 2 are arranged in a one-to-one correspondence, that is, when the control board 5 moves, the multiple insertion rods 51 are driven to move simultaneously. When it is necessary to replace battery cells of different specifications, the battery cell of the specification is first placed on the suction nozzle 2, and the air is pumped so that the inside of the cavity 11 is in a negative pressure state, and the suction nozzle 2 is adsorbed on the battery cell. At this time, the sealing plate 3 in the suction nozzle 2 that has not adsorbed the battery cell rotates to the through hole 21. After the sealing plates 3 in all the suction nozzles 2 that have not been adsorbed have rotated to the through hole 21, the control board 5 is moved, and the control board 5 drives the multiple insertion rods 51 to be inserted into the insertion hole 31 to fix the sealing plate 3, that is, all the suction nozzles 2 that have not been adsorbed are closed and kept closed, so that the opened suction nozzles 2 correspond to the specifications of the battery cell. When the battery cells of this specification are subsequently loaded, the control board 5 is fixed relative to the suction cup 1, and the battery cell is loaded through the opened suction nozzle 2. When it is necessary to change the battery cells of different specifications again, the control board 5 is moved to the initial position, the insertion rod 51 is separated from the insertion hole 31, and the above operation is repeated. When loading battery cells of different specifications, the number of suction nozzles 2 and the suction position are set first to improve the loading effect of the battery cells.

[0046] Reference Figure 6 and Figure 7A positioning plate 6 is provided on the inner wall of the suction nozzle 2. When the sealing plate 3 rotates to abut against the side of the positioning plate 6, the socket 31 rotates to the middle hole 23 so that the insertion rod 51 can be inserted into the socket 31 through the middle hole 23. A sensing member is provided on the positioning plate 6. The sensing member is used to detect whether the sealing plate 3 abuts against the positioning plate 6. In this embodiment, the sensing member can be set as an infrared sensor. A controller is provided on the suction cup 1. The signal output end of the sensing member is electrically connected to the signal receiving end of the controller. A push member 13 is provided on the suction cup 1. The push member 13 can be set as a cylinder. The output end of the cylinder is connected to the control board 5 for adjusting the position of the control board 5. The control end of the controller is electrically connected to the switch of the push member 13. When adjusting the number of suction nozzles 2, after the sensing component detects that the sealing plate 3 is in contact with the positioning plate 6, the jack 31 corresponds to the middle hole 23, and the sensing component sends a signal to the controller. The controller controls the push member 13 to start, and the push member 13 drives the control plate 5 to move, closing the suction nozzles 2 that are not adsorbed, so as to adjust the number of suction nozzles 2.

[0047] Reference Figure 6 and Figure 7 After fixing the number of open suction nozzles 2 and the adsorption position, when there are defects or impurities on the surface of the battery cell, some suction nozzles 2 will not be able to adsorb on the battery cell. In addition, when the number of open suction nozzles 2 is adjusted according to the specifications of the battery cell, the control board 5 moves to drive all the insertion rods 51 to move into the middle hole 23, that is, there are also insertion rods 51 in the open suction nozzles 2. When some suction nozzles 2 cannot adsorb the battery cell, there will be continuous airflow inside, causing the sealing plate 3 to rotate toward the middle rod until the side of the sealing plate 3 abuts against the side of the insertion rod 51. At this time, the sealing plate 3 closes the through hole 21 and stops the adsorption of the suction nozzle 2.

[0048] Reference Figure 8 and Fig. 9 A mounting block 8 is provided on the mounting rod 7, a clamping block 81 is slidably provided on the mounting block 8, a spring is provided inside the mounting block 8, the spring and the clamping block 81 are connected to drive the clamping block 81 to slide in a direction away from the mounting rod 7, a rotating sleeve 411 is provided on the rotating rod 41, the rotating sleeve 411 is arranged on the outside of the clamping block 81, and a clamping groove 412 is opened on the inner wall of the rotating sleeve 411, after the sealing plate 3 is rotated to abut against the side of the insertion rod 51, the clamping block 81 and the clamping groove 412 are buckled to fix the rotating rod 41 and the sealing plate 3 to close the suction nozzle 2 that cannot be adsorbed on the battery cell.

[0049] Reference Figure 8 and Fig. 9The mounting block 8 is slidably arranged on the mounting rod 7 along the vertical direction, that is, the mounting block 8 is slidably arranged in the direction toward the rotating sleeve 411. A plurality of slots 412 are provided around the axis of the rotating rod 41. An adjusting member 9 for adjusting the position of the mounting block 8 is provided on the suction nozzle 2. A slope is provided on one side of the block 81. When the rotating sleeve 411 rotates, the block 81 can be engaged with different slots 412 in sequence under the action of the slope of the block 81. In the initial state, the block 81 and the slot 412 are arranged at intervals. When the battery cell is sucked and adsorbed, the adjusting member 9 drives the mounting block 8 to move, so that the block 81 moves into the rotating sleeve 411, so that the block 81 and the slot 412 can be engaged to fix the sealing plate 3.

[0050] Reference Figures 2 to 8 The nozzle 2 is provided with a slide frame 12, and an opening is provided on one side of the slide frame 12 close to the cavity 11. A mounting groove 71 is provided in the mounting rod 7, and a slide groove 72 connected to the mounting groove 71 is provided on the side of the mounting rod 7. The mounting block 8 is slidably arranged in the slide groove 72. The adjusting member 9 includes a slide plate 91 and a connecting rod 92. The slide plate 91 is slidably arranged in the slide frame 12 in the direction toward the cavity 11, and the connecting rod 92 is arranged along the length direction of the mounting rod 7, and the connecting rod 92 is slidably arranged in the mounting rod 7. The side of the mounting block 8 extends into the mounting groove 71 and is connected to the connecting rod 92, and the end of the connecting rod 92 away from the mounting block 8 extends into the slide frame 12 and is connected to the slide plate 91. The slide plate 91 is arranged perpendicular to its sliding direction, and the slide plate 91 divides the slide frame 12 into two areas. A second elastic member 921 is provided outside the connecting rod 92 . The second elastic member 921 can be set as a spring. Both ends of the spring are respectively connected to the slide plate 91 and the side wall of the suction nozzle 2 . The second elastic member 921 is used to drive the slide plate 91 to slide in a direction away from the cavity 11 .

[0051] In the initial state, the mounting block 8 and the rotating sleeve 411 are arranged at intervals, and the slide plate 91 and the opening of the slide frame 12 are also arranged at intervals. When the air is evacuated so that the cavity 11 is in a negative pressure state, the slide plate 91 moves under the action of the negative pressure. The movement of the slide plate 91 drives the mounting block 8 to move through the connecting rod 92, and stretches the second elastic member 921 until the block 81 moves into the rotating sleeve 411. At this time, the sealing plate 3 is fixed. If the suction nozzle 2 is adsorbed on the battery cell, the slide plate 91 and the block 81 are moved back to the initial position under the action of the second elastic member 921. If the suction nozzle 2 is not adsorbed on the battery cell, the blade 42 continues to rotate until it drives the sealing plate 3 to rotate. After the sealing plate 3 rotates to abut against the insertion rod 51, it stops rotating, and the block 81 is clamped in the corresponding slot 412 to fix the sealing plate 3. After the battery cell is conveyed, the air pressure in the cavity 11 is normal, the block 81 and the slide plate 91 return to their initial positions under the action of the second spring 921, the block 81 is separated from the slot 412, and the sealing plate 3 rotates to its initial position so as to absorb the battery cell again for loading.

[0052] Reference Figures 5 to 8 In order to facilitate the sliding of the slide plate 91 in the slide frame 12, a through pipe 121 is provided on the slide frame 12. The through pipe 121 is arranged on the side of the slide plate 91 away from the cavity 11. One end of the through pipe 121 is connected with the inside of the slide frame 12, and the other end is arranged outside the slide frame 12. That is, the through pipe 121 is used to connect the inside of the slide frame 12 with the outside, so that the slide frame 12 on the side of the slide plate 91 away from the cavity 11 is in a state of normal air pressure, so that the slide plate 91 moves under the action of the negative pressure of the cavity 11, or moves to the initial position under the action of the elastic member 921.

[0053] The implementation principle of the present invention is as follows: before loading the battery cell, place the battery cell on the side of the suction cup 1 close to the suction nozzle 2, and evacuate the air so that the inside of the cavity 11 is in a negative pressure state. The suction nozzle 2 is adsorbed on the battery cell. At this time, the suction nozzle 2 adsorbed on the battery cell will only generate a short airflow during the adsorption process, and the torsion amplitude of the elastic member 43 is small, and the corresponding sealing plate 3 is stationary. A continuous airflow will be generated in the suction nozzle 2 that is not adsorbed on the battery cell. The continuous airflow drives the rotating rod 41 to rotate through the blade 42. After the rotation of the rotating rod 41 drives the elastic member 43 to be subjected to a certain degree of force, the sealing plate 3 is driven to separate from the top block 22 and rotate. The sealing plate 3 rotates to the positioning plate 6, and the plug hole 31 corresponds to the middle hole 23. After detecting that the sealing plate 3 rotates to the positioning plate 6, the sensing element sends a signal to the controller. After receiving the signal, the controller controls the push piece 13 to start, and the push piece 13 drives the control plate 5 to move. The movement of the control plate 5 drives multiple insertion rods 51 to move simultaneously and insert into the corresponding middle holes 23. At the same time, the insertion rod 51 is inserted into the sealing plate 3 in the non-absorbed suction nozzle 2 to fix the sealing plate 3, and then the suction nozzle 2 is closed, and multiple non-absorbed suction nozzles 2 are closed at the same time to determine the number of suction nozzles 2 required for the battery cell of this specification and the position of each suction nozzle 2. Subsequently, when loading the battery cell of this specification, the control board 5 is fixed relative to the suction cup 1. In addition, when changing the specification of the battery cell, the control board 5 is moved to the initial position, and the above operation is repeated again to load battery cells of different specifications.

[0054] By determining the number and position of the suction nozzles 2 according to the specifications of the battery cells before loading, the stability of loading the battery cells of this specification can be ensured. At the same time, the energy waste caused by the suction nozzles 2 constantly pumping air can be reduced, and the battery cells can be reduced from falling off due to unstable negative pressure in the cavity 11, thereby improving the loading efficiency and quality of the battery cells.
