Description

Technical Field

[0001] The present invention relates to the technical field of battery module processing, and particularly relates to a conveying device for battery module production. Background Art

[0002] A photovoltaic cell module is a photovoltaic component. Among them, a photovoltaic cell is the core component unit of the photovoltaic cell module. A photovoltaic cell is the smallest functional unit for photovoltaic power generation, responsible for converting light energy into electrical energy, and its base material is a silicon wafer. During production, through screen printing technology, materials such as conductive silver paste are precisely printed on the silicon wafer to form the positive and negative electrodes of the battery. This process is crucial for the conductive performance and conversion efficiency of solar cells. When printing battery chips, the battery chips need to be stacked in a feeding frame, and the feeding frame supplies materials to the printing equipment for subsequent processing.

[0003] A patent application document with the publication number CN109305557A discloses a feeding device for battery chip production, including a vacuum suction cup arranged above a placement basket. The battery chips are stacked and placed in the placement basket. After the vacuum suction cup sucks the battery chips from the placement basket and moves, it feeds the battery chips.

[0004] The above feeding device further includes a fixed seat. Both sides of the outer wall of the top of the fixed seat are installed with support seats through bolts, and the outer wall of the top of the support seat is installed with a ventilation seat through bolts. A ventilation hole is opened at the middle position of the outer wall of the top of the ventilation seat. By blowing air through the ventilation hole to the battery chips, the top battery chips are blown up to avoid the vacuum suction cup sucking multiple battery chips at the same time, and then the battery chips are sucked by the vacuum suction cup for feeding.

[0005] However, the following problems still exist in this solution. When blowing up the top battery chips to suck the topmost battery chip, the battery chips will shake while separating from the other battery chips. Therefore, the position of the separated battery chips will change, and at the same time, the position of the battery chips relative to the vacuum suction cup will also change, resulting in easy positioning deviation when the suction cup sucks the battery chips and affecting the subsequent printing accuracy. Summary of the Invention

[0006] The present invention provides a conveying device for battery module production, aiming to solve the problem of easy positioning deviation of battery chips during feeding in related technologies.

[0007] The conveying device for battery module production of the present invention includes a suction cup for sucking battery chips. Around the center of the suction cup, first and second adjustment devices are provided. Both the first and second adjustment devices include a pushing-off component, a correction component, a driver, and a transmission component;

[0008] The push-off assembly includes a push wheel that is mounted in an opening at the lower end of the suction cup and moves up and down; the correction assembly includes a pair of correction plates that are mounted on the suction cup and move horizontally, and the two correction plates are arranged opposite to each other and correspond to two opposite sides of the battery sheet; the driver is connected to the push wheel and the correction plate through the transmission assembly; the driver drives the push wheel to move up and down and drives the correction plate to move horizontally at the same time through the transmission assembly;

[0009] The travel of the push wheel includes a lower position for pushing the battery sheet downward to leave the adsorption surface at the lower end of the suction cup, and an upper position for receiving the battery sheet in the opening; the travel of the two correction plates includes a correction position for pushing the battery sheet close to each other to align with the center of the adsorption surface of the suction cup, and a separation position for moving away from the battery sheet; the push wheel in the upper position is synchronously moved into position with the correction plate in the correction position, and the push wheel in the lower position is synchronously moved into position with the correction plate in the separation position;

[0010] The push wheel of the first adjusting device has a synchronous stroke with the push wheel of the second adjusting device but moves in opposite directions; the correction plate of the first adjusting device has a synchronous stroke with the correction plate of the second adjusting device but moves in perpendicular directions; the correction plate of the first adjusting device and the correction plate of the second adjusting device are alternately in the correction position and abut against the side of the battery cell to drive the battery cell to move to the center of the suction cup.

[0011] The effect is that, since the present invention is equipped with two groups of adjustment devices, and the movement of the adjustment devices is synchronous movement, but the movement directions of the execution components are opposite, after such configuration, the push wheel in the first group of adjustment devices can push the battery cell away from the suction cup, and the correction plate in the first group of adjustment devices can move to abut against the battery cell to correct it. That is, when the push wheel moves to the lower stroke state, it drives the battery cell to separate from the suction cup, and then the correction plate in the correction position is used to adjust the center of the battery cell in its moving direction, and then the push wheel and the correction plate of the second adjustment device are used to repeat the above action to realize the correction of the battery cell in another vertical direction, so that the battery cell corresponds to the center of the suction cup, thereby eliminating the positioning deviation when the suction cup absorbs the battery cell. In addition, when the battery cell moves, the push wheel rotates accordingly to cooperate with the correction plate to adjust the position of the battery cell.

[0012] Preferably, the push-off assembly further comprises a placement rack, the push wheel is rotatably arranged on the placement rack, the placement rack moves downward in the opening, the correction assembly further comprises a mounting rack for mounting the correction plate, the mounting rack slides on the suction cup toward the center direction of the suction cup, and the transmission assembly is connected to the placement rack and the mounting rack;

[0013] The transmission assembly adjusts the position of the push wheel through the placement frame and adjusts the position of the correction plate through the installation frame.

[0014] The effect is that by configuring the transmission component to be connected to the placement rack and the mounting rack, the driver can drive the placement rack to move through the transmission component. The placement rack moves towards the outside of the opening to adjust the position of the pushing wheel, so as to drive the solar cell to separate from the suction cup through the pushing wheel for subsequent adjustment. The transmission component drives the correction plate to move through the mounting rack, so that the correction plate approaches or moves away from the solar cell, realizing the control of the positions of the pushing wheel and the correction plate.

[0015] Preferably, the transmission component includes a control ring movably assembled up and down at the upper end of the suction cup, a push rod connected to the mounting rack, and a connecting rod connected to the placement rack;

[0016] Both ends of the push rod are rotatably fitted with the mounting rack and the control ring respectively. The push rod is inclined. The connecting rod extends to the upper end of the suction cup and is connected to the control ring. The output end of the driver is connected to the control ring;

[0017] The driver drives the control ring to move up and down. The movement of the control ring drives the pushing wheel to move through the connecting rod and the placement rack. At the same time, the rotation of the push rod drives the mounting rack and the correction plate to move.

[0018] The effect is that the driver drives the control ring to move. The movement of the control ring drives the mounting rack to move through the push rod, and at the same time drives the placement rack to move through the connecting rod, thereby realizing the adjustment of the positions of the correction plate and the pushing wheel.

[0019] Preferably, the transmission components in the first adjustment device are respectively connected to the pushing wheel in the first adjustment device and the correction plate in the second adjustment device. The transmission components in the second adjustment device are respectively connected to the pushing wheel in the second adjustment device and the correction plate in the first adjustment device. One end of the push rod connected to the mounting rack is inclined towards the direction of the suction cup, so that when the pushing wheel in the first / second adjustment device moves to push the solar cell, the correction plate in the second / first adjustment device moves away from the solar cell.

[0020] The effect is that the two control rings move in opposite directions, simultaneously driving the same group of pushing wheels and correction plates to move to correct the solar cell. The two control rings alternately move in opposite directions, realizing the alternate adjustment of the two groups of pushing wheels and correction plates to the solar cell. So as to control the pushing wheel to push the solar cell away from the suction cup and then adjust the position of the solar cell through the correction plate.

[0021] Preferably, the mounting rack includes an elastic telescopic rod. The elastic telescopic rod is arranged along the sliding direction of the correction plate, and the correction plate is connected to the elastic telescopic rod.

[0022] The effect is that when the correction plate abuts against the solar cell, the elastic telescopic rod can undergo elastic deformation, reducing the occurrence of hard contact between the correction plate and the solar cell and protecting the solar cell.

[0023] Preferably, the connecting rod includes a sleeve rod and an inner rod. The sleeve rod is connected to the control ring. The inner rod is slidably arranged within the sleeve rod. The inner rod is connected to the placement rack. A resilient member connected to the inner rod is arranged within the sleeve rod. When the calibration plate in the first / second adjustment device moves closer to the solar cell, the inner rod slides relative to the sleeve rod, and the pushing wheel in the second / first adjustment device is located within the opening.

[0024] The effect is that when the control ring drives the calibration plate to move towards the solar cell, the inner rod corresponding to the control ring slides within the sleeve rod, and the placement rack and the pushing wheel are located within the opening, reducing the phenomenon that the placement rack interferes with the movement of the control ring. Additionally, a resilient member is arranged between the inner rod and the sleeve rod, which can reduce the phenomenon of hard contact when the pushing wheel abuts against the solar cell, reduce damage to the solar cell, and protect the solar cell.

[0025] Preferably, each set of pushing-off components includes at least two pushing wheels. The rotation axes of the multiple pushing wheels are parallel to each other. The multiple pushing wheels abut against multiple locations on the solar cell to drive the solar cell to separate from the suction cup.

[0026] The effect is that by arranging multiple pushing wheels, the force-bearing area after the solar cell separates from the suction cup is increased, thereby enhancing the stability of the solar cell during movement. At the same time, the phenomenon that the solar cell is damaged due to excessive local force can be reduced.

[0027] Preferably, multiple rubber rings are coaxially sleeved outside the pushing wheel. The multiple rubber rings are arranged at intervals along the axial direction of the pushing wheel.

[0028] The effect is that the rubber rings contact the solar cell, enhancing the friction between the solar cell and the pushing wheel. At the same time, when the solar cell moves, it drives the pushing wheel to rotate. Under the action of the rubber rings, the solar cell is reduced from moving in a direction deviating from the rotation direction of the pushing wheel, so as to adjust the solar cell to a specified position.

[0029] Preferably, an extension rack and an extension rod are arranged on the side surface of the control ring. The push rod is connected to the connecting frame, and the connecting rod is connected to the extension rod. The extension rack and the extension rod on another control ring are arranged along the sliding direction of the control ring.

[0030] The effect is that by arranging the extension rack and the extension rod, the phenomenon that the push rod interferes with the connecting rod on another control ring is reduced, enabling the overall structure to operate stably.

[0031] Beneficial effects:

[0032] 1. During feeding, the suction cup sucks the solar cell. After the suction cup sucks the solar cell, the solar cell is driven to move by the pushing wheel and the calibration plate. At the same time, under the action of another set of pushing wheel and calibration plate, the solar cell is driven to move in another perpendicular direction. The two sets of pushing wheels and calibration plates alternately adjust the position of the solar cell, adjusting the solar cell to correspond to the center of the suction cup to eliminate the deviation when the suction cup sucks the solar cell, facilitating the placement of the solar cell at a specified position and improving the subsequent printing accuracy.

[0033] 2. The pushing wheels and the calibration plates in each set of adjusting components are respectively connected to two control rings. When calibrating the battery cells, the pushing wheels and the calibration plates in the two sets of adjusting devices work synchronously, driving the corresponding pushing wheels to move and cooperate with the battery cells, and the corresponding calibration plates move towards the battery cells. When the driver drives the control rings to move in the reverse direction, the positions of the battery cells in the other vertical direction are adjusted so as to adjust the battery cells to the specified positions. And during the adjustment, the movement of the control rings drives the movement of the pushing wheels, and the pushing wheels push the battery cells to separate from the suction cups. The other control ring can continuously drive the calibration plate to move until the battery cells are adjusted to the specified positions. This setting enables the calibration plate to have a larger movement stroke and improves the adjustment effect on the battery cells.

[0034] 3. The two control rings move synchronously in opposite directions. While driving the pushing wheels to push the battery cells, the other calibration plate moves in the direction away from the battery cells, and the inner rod corresponding to the other pushing wheel slides in the sleeve rod, and the pushing wheel remains stationary in the opening, reducing the phenomenon that the pushing wheel interferes with the movement of the battery cells, so that the two sets of pushing wheels and calibration plates alternately adjust the positions of the battery cells.

Detailed Description of the Invention

[0046] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] Referring to Figure 1 , the conveying device for producing a battery module according to the present invention (hereinafter simply referred to as the feeding device) is installed on one side of the printing device 1 when in use.

[0048] Referring to Figure 2 and Figure 3 , the feeding device includes a frame 11, a loading frame 2, a transfer mechanism, a suction cup 3, and an adjusting device. The loading frame 2 is used for stacking and placing the battery cells 01. The transfer mechanism is installed on the top of the frame 11 and is used to drive the suction cup 3 to transfer between the loading frame 2 and the printing device 1. The transfer mechanism includes a horizontally extending horizontal guide rail, a trolley that moves left and right on the horizontal guide rail, and a lifting arm connected to the lower part of the trolley. Referring to Figures 1 to 3 , the suction cup 3 is installed at the lower end of the lifting arm of the transfer mechanism. The adsorption surface of the suction cup 3 faces downward and is arranged towards the loading frame 2.

[0049] When the feeding device is working, the battery cells 01 are adsorbed by the suction cup 3, and the transfer mechanism drives the suction cup 3 to move to the printing device 1. After placing the battery cells 01 at the printing device 1, the feeding operation of a single battery cell 01 is completed. The above actions are repeated continuously to supply the battery cells 01.

[0050] Referring to Figures 3 to 5, The adjusting device is installed on the suction cup 3. There are two sets of adjusting devices corresponding to the two pairs of side edges of the rectangular solar cell 01, which are respectively: the first adjusting device 41 for adjusting the position of the solar cell 01 back and forth, and the second adjusting device 42 for adjusting the position of the solar cell 01 left and right. The first adjusting device 41 is arranged corresponding to the front and back sides of the solar cell 01, and the second adjusting device 42 is arranged corresponding to the left and right sides of the solar cell 01. The first adjusting device 41 and the second adjusting device 42 cooperate to centeringly adjust the position of the solar cell 01. Here, centering refers to the central axis of the adsorption surface of the suction cup 3. That is, by successively pushing and adjusting the positions of the front and back sides and the left and right sides of the solar cell 01 through the first adjusting device 41 and the second adjusting device 42, the center of the solar cell 01 is made to correspond to the center of the suction cup 3, so as to eliminate the deviation that occurs when the suction cup 3 adsorbs the solar cell 01 and improve the subsequent printing accuracy.

[0051] Since the structures of the first adjusting device 41 and the second adjusting device 42 are the same, the following will refer to Figures 3 to 8 to introduce the first adjusting device 41.

[0052] Referring to Figures 3 to 8 , the first adjusting device 41 includes a pushing-away component 5, a correcting component 6, a driver 7 and a transmission component 8. The driver 7 is connected to the pushing-away component 5 and the correcting component 6 through the transmission component 8 and controls both of them. The pushing-away component 5 cooperates with the upper surface of the solar cell 01 and is used to push the solar cell 01 to separate from the adsorption surface of the suction cup 3. The correcting component 6 cooperates with two opposite side surfaces of the solar cell 01 and corrects the position of the solar cell 01 by horizontally pushing the solar cell 01, so as to realize the adjustment of the position of the solar cell 01.

[0053] Referring to Figure 5 and Figure 6 , the pushing-away component 5 includes a pushing wheel 51 and a placement rack 52 for installing the pushing wheel 51. The pushing wheel 51 is rotatably arranged on the placement rack 52. An opening 34 is provided at the lower end of the suction cup 3. The placement rack 52 slides in the opening 34 along the direction perpendicular to the adsorption surface. While the placement rack 52 moves in the opening 34, it drives the pushing wheel 51 to move. The transmission component 8 is connected to the placement rack 52, and the driver 7 adjusts the position of the placement rack 52 through the transmission component 8.

[0054] Referring to Figure 3 and Figure 5, each set of pushing and separating components 5 includes two pushing wheels 51. The two pushing wheels 51 are symmetrically arranged around the center of the suction cup 3, and the rotation axes of the two pushing wheels 51 are parallel to each other. When the pushing wheels 51 cooperate with the solar cell 01, the contact area with the solar cell 01 is increased, thereby improving the stability of the solar cell 01. At the same time, the two pushing wheels 51 are evenly separated on the suction cup 3, so that the solar cell 01 is evenly stressed, so as to adjust the solar cell 01 to a specified position. In addition, the number of pushing wheels 51 can be adaptively adjusted according to the size of the solar cell 01, which can further improve the stability when the solar cell 01 is separated from the suction cup 3. In addition, by making multiple pushing wheels 51 contact the solar cell 01 at the same time, the phenomenon of deformation when the solar cell 01 is separated from the suction cup 3 is reduced, and the solar cell 01 can be protected while correcting the position of the solar cell 01.

[0055] In the initial state, the pushing wheels 51 are within the opening 34. The suction cup 3 sucks the solar cell 01 from the feeding frame 2. The solar cell 01 abuts against the adsorption surface. The placement rack 52 moves to drive the pushing wheels 51 to move downward to the outside of the opening 34 and cooperate with the solar cell 01. The pushing wheels 51 drive the solar cell 01 to separate from the suction cup 3 and remain in contact with the solar cell 01, so that there is a certain gap between the solar cell 01 and the adsorption surface. Then, the position of the solar cell 01 is adjusted by the calibration component 6, and the position of the solar cell 01 is adjusted in cooperation with the calibration component 6. When the solar cell 01 moves, the pushing wheels 51 rotate accordingly to reduce the friction force when the solar cell 01 moves, facilitate the adjustment of the position of the solar cell 01, and at the same time reduce the phenomenon of damage to the solar cell 01.

[0056] After the pushing wheels 51 drive the solar cell 01 to separate from the adsorption surface of the suction cup 3, at this time, the gap between the solar cell 01 and the suction cup 3 is small, and the suction nozzles on the suction cup 3 are continuously in a negative pressure state during the feeding process, so that the solar cell 01 can still be indirectly adsorbed on the suction cup 3, reducing the phenomenon that the solar cell 01 falls off the suction cup 3 when it is pushed to separate from the suction cup 3.

[0057] Refer to Figure 8 , rubber rings 9 are arranged on the side surface of the pushing wheels 51. There are multiple rubber rings 9, and the multiple rubber rings 9 are arranged at intervals along the length direction of the pushing wheels 51. That is, the pushing wheels 51 contact the solar cell 01 through the rubber rings 9, reducing the phenomenon of damage to the solar cell 01. At the same time, the friction force between the solar cell 01 and the pushing wheels 51 is increased through the rubber rings 9, so that the solar cell 01 can move along with the rotation direction of the pushing wheels 51, reducing the phenomenon of deviation during the movement of the solar cell 01, so as to adjust the solar cell 01 to a specified position.

[0058] Refer to Figure 5 and Figure 6The correction component 6 includes a correction plate 61 and a mounting frame 62. Two correction plates 61 are mounted on the lower end of the suction cup 3 and are movable in the horizontal direction. The two correction plates 61 are arranged opposite to each other and correspond to two opposite sides of the battery cell 01. The mounting frame 62 is slidably arranged on the suction cup 3 in the direction toward the center of the adsorption surface. The correction plate 61 is connected to the mounting frame 62, that is, the mounting frame 62 slides and drives the correction plate 61 to move. The transmission component 8 is connected to the mounting frame 62. The sliding direction of the correction plate 61 is arranged perpendicular to the rotation axis of the push wheel 51.

[0059] Reference Figure 6 and Figure 7 After the push wheel 51 drives the battery cell 01 to separate from the adsorption surface of the suction cup 3, the driver 7 drives the two correction plates 61 to move synchronously toward the battery cell 01 through the transmission assembly 8. The two correction plates 61 move toward the battery cell 01 at the same time until the two correction plates 61 abut against the side of the battery cell 01 at the same time. At this time, the battery cell 01 moves in this direction to correspond to the center of the suction cup 3.

[0060] Reference Figure 5 and Figure 6 The mounting frame 62 includes an elastic telescopic rod 621, a spring is arranged inside the elastic telescopic rod 621, and the elastic telescopic rod 621 is connected to the correction plate 61. When the correction plate 61 cooperates with the battery cell 01, the spring will be deformed, that is, the elastic telescopic rod 621 will be stretched and retracted, thereby reducing the phenomenon of damage to the battery cell 01 caused by hard contact between the correction plate 61 and the battery cell 01, and protecting the battery cell 01.

[0061] Reference Figures 2 to 5 The transmission assembly 8 includes a mounting column 31, a control ring 81, a push rod 82, and a connecting rod 521. The mounting column 31 is arranged on the upper side of the suction cup 3. The control ring 81 is sleeved on the outside of the mounting column 31, and the control ring 81 is slidably arranged on the mounting column 31 in the direction of the suction cup 3. The connecting rod 521 is connected to the placement frame 52, and the connecting rod 521 passes through the suction cup 3 upward and is connected to the control ring 81. The end of the mounting frame 62 away from the correction plate 61 bypasses the edge of the suction cup 3 and is arranged at the upper end of the suction cup 3. The first end of the push rod 82 is rotatably matched with the control ring 81, and the second end is rotatably connected with the mounting frame 62. The end of the push rod 82 close to the mounting frame 62 is tilted in the direction toward the suction cup 3. The driver 7 is configured as a cylinder, and the output end of the cylinder is connected to the control ring 81.

[0062] The driver 7 drives the control ring 81 to move, and the movement of the control ring 81 drives the push wheel 51 to move through the connecting rod 521, and at the same time drives the push rod 82 to rotate. The rotation of the push rod 82 drives the mounting frame 62 to move, and the movement of the mounting frame 62 drives the correction plate 61 to move, thereby adjusting the positions of the correction plate 61 and the push wheel 51 at the same time.

[0063] ReferenceFigure 5 and Figure 6 The transmission components 8 in the first adjusting device 41 are respectively connected to the push wheel 51 in the first adjusting device 41 and the correction plate 61 in the second adjusting device 42, and the transmission components 8 in the second adjusting device 42 are respectively connected to the correction plate 61 in the first adjusting device 41 and the push wheel 51 in the second adjusting device 42.

[0064] Specifically, the control ring 81 in the first adjusting device 41 drives the push wheel 51 in the first adjusting device 41 to move synchronously with the correction plate 61 in the second adjusting device 42, and the control ring 81 in the second adjusting device 42 drives the correction plate 61 in the first adjusting device 41 to move synchronously with the push wheel 51 in the second adjusting device 42. That is, the two control rings 81 act together to drive the push wheel 51 and the correction plate 61 in the first adjusting device 41 or the second adjusting device 42 to move synchronously.

[0065] Specifically, when the control ring 81 in the first adjusting device 41 moves downward, it drives the push wheel 51 in the first adjusting device 41 to move downward to push against the battery cell 01. When the control ring 81 in the second adjusting device 42 moves upward, it drives the correction plate 61 in the first adjusting device 41 to move towards the battery cell 01. The movement of the control ring 81 in this process is defined as forward movement; when the control ring 81 in the second adjusting device 42 moves downward, it drives the push wheel 51 in the second adjusting device 42 to push against the battery cell 01, and when the control ring 81 in the first adjusting device 41 moves downward, it drives the correction plate 61 in the second adjusting device 42 to move towards the battery cell 01. The movement of the control ring 81 in this process is defined as reverse movement. That is, the two drivers 7 drive the corresponding control rings 81 to move forward and reverse synchronously, so as to realize the correction adjustment of the battery cell 01 in the front-back and left-right directions.

[0066] Refer to Figure 5 and Figure 6 An extension frame 811 and an extension rod 812 are arranged on the side surface of the control ring 81. The push rod 82 is connected to the extension frame 811, and the connecting rod 521 is connected to the extension rod 812. The extension frame 811 and the extension rod 812 on another control ring 81 are arranged along the length direction of the mounting column 31, that is, the extension frame 811 and the extension rod 812 are arranged along the sliding direction of the control ring 81. One of the connecting rods 521 passes through the extension frame 811 and is connected to the extension rod 812 on the control ring 81 far from the suction cup 3. By arranging the extension frame 811 and the extension rod 812, the phenomenon that the two groups of connecting rods 521 and the push rod 82 interfere with each other during movement is reduced, and the overall stability is improved.

[0067] Refer to Figure 5 and Figure 8, the connecting rod 521 includes a sleeve rod 522 and an inner rod 523. The sleeve rod 522 is connected to the control ring 81, the inner rod 523 is slidably arranged within the sleeve rod 522, the inner rod 523 is connected to the placement rack 52, and an elastic member 524 is arranged within the sleeve rod 522. The elastic member 524 is set as a spring. One end of the spring is connected to the inner wall of the sleeve rod 522, and the other end is connected to the inner rod 523. When the control ring 81 moves to drive the corresponding correction plate 61 to move towards the battery cell 01, the control ring 81 pulls the sleeve rod 522. At this time, the push wheel 51 is located within the opening 34, and the inner rod 523 slides within the sleeve rod 522, reducing the phenomenon that the connecting rod 521 interferes with the movement of another set of correction plates 61. Additionally, by arranging the elastic member 524 within the sleeve rod 522, when the sleeve rod 522 and the inner rod 523 move to cooperate with the battery cell 01, it can prevent the hard contact between the push wheel 51 and the battery cell 01, avoiding the phenomenon that the surface of the battery cell 01 is damaged due to excessive instantaneous force, and protecting the battery cell 01.

[0068] A first sliding seat 32 and a second sliding seat 33 are arranged on the suction cup 3. The mounting frame 62 is slidably matched with the first sliding seat 32, and the sleeve rod 522 is slidably matched with the second sliding seat 33, that is, the sleeve rod 522 is slidably arranged on the suction cup 3 through the second sliding seat 33. By arranging the first sliding seat 32 and the second sliding seat 33, the stability of the movement of the sleeve rod 522 and the mounting frame 62 is improved.

[0069] After the push wheel 51 pushes the battery cell 01 to separate from the suction cup 3, another set of drivers 7 and transmission components 8 drive the correction plate 61 to move. The two sets of drivers 7 and transmission components 8 alternately drive the corresponding push wheels 51 and correction plates 61 to move, adjusting the battery cell 01 to the specified position.

[0070] The rotation axes of the push wheels 51 within the first adjustment device 41 and the push wheels 51 within the second adjustment device 42 are perpendicular to each other, and the sliding directions of the two sets of correction plates 61 are also perpendicular to each other. That is, the first adjustment device 41 and the second adjustment device 42 adjust the battery cell 01 along two mutually perpendicular directions respectively to achieve the centering adjustment of the battery cell 01.

[0071] Additionally, an induction member is arranged on the elastic telescopic rod 621, and a controller is arranged on the suction cup 3. The induction member is electrically connected to the signal receiving end of the controller. The induction member is set as an infrared sensor, and the control end of the controller is electrically connected to the switch of the driver 7 for controlling the driver 7. The induction member is used to detect the telescopic amount of the elastic telescopic rod 621. By arranging two correction plates 61 within both the first adjustment device 41 and the second adjustment device 42, after the correction plates 61 correct the position of the battery cell 01, the deformation amounts of the elastic telescopic rods 621 are the same, that is, the telescopic amounts of the elastic telescopic rods 621 are the same.

[0072] When the alignment plate 61 aligns the solar cell 01, the sensor detects the amount of expansion and contraction of the elastic telescopic rod 621. After each alignment action of the alignment plate 61, the sensor sends the signal of the detected amount of expansion and contraction of the elastic telescopic rod 621 to the controller, and the controller judges the amounts of expansion and contraction of the two elastic telescopic rods 621.

[0073] If the amounts of expansion and contraction of the two elastic telescopic rods 621 are different, that is, there is a difference in the amounts of expansion and contraction, it means that the alignment of the solar cell 01 in this direction is not completed. At this time, the driver 7 continues to work and repeatedly drives the alignment plate 61 to adjust the solar cell. That is, in two perpendicular adjustment directions, as long as there is one direction in which the adjustment is not completed, the driver 7 will continue to work.

[0074] If the amounts of expansion and contraction of the two elastic telescopic rods 621 are the same, that is, there is no difference in the amounts of expansion and contraction of the two elastic telescopic rods 621, it is determined that the alignment of the solar cell 01 in this direction is completed. And when the amounts of expansion and contraction of the elastic telescopic rods 621 corresponding to the other set of alignment plates 61 are also the same, it is regarded that the alignment of the solar cell 01 in the other perpendicular direction is also completed. At this time, the controller controls the driver 7 to stop working, and the alignment of the solar cell 01 is completed.

[0075] A vision sensor is arranged on the suction cup 3. The signal output end of the vision sensor is electrically connected to the signal receiving end of the controller. The vision sensor has two detection modes. One is to detect whether there is a deviation in the position of the solar cell 01 when the solar cell 01 is not adsorbed on the suction cup 3, and the other mode is to detect whether there is a deviation in the position of the solar cell 01 relative to the suction cup 3 after the solar cell 01 is adsorbed on the suction cup 3. In both detection modes, when the position deviation of the solar cell 01 is detected and after the solar cell 01 is adsorbed on the suction cup 3, the controller controls the driver 7 to start and correct the position of the solar cell 01. If both detection modes do not meet the requirements, it is regarded that there is no deviation when the suction cup 3 sucks the solar cell 01. After the suction cup 3 adsorbs the solar cell 01, the driver 7 does not work, that is, the alignment plate 61 is stationary, and the pushing wheel 51 is in the opening 34, and it is normally transported and fed.

[0076] In this embodiment, the transfer mechanism is set as a cylinder. The cylinder is arranged above the feeding frame 2. The output end of the cylinder is connected to the suction cup 3 and its output end faces the printing device 1. The cylinder drives the suction cup 3 to reciprocate between the feeding frame 2 and the printing device 1 to continuously transfer the solar cells 01 in the feeding frame 2 to the printing device 1.

[0077] Refer to Figure 9, a pallet 21 is arranged in the feeding frame 2, a screw rod 22 is rotatably arranged on the frame 11, the end of the screw rod 22 is connected to the pallet 21, a motor can be arranged at the other end of the screw rod 22, and the screw rod 22 is in threaded fit connection with the frame 11. The battery wafers 01 are stacked and placed on the pallet 21. With continuous feeding, the motor drives the screw rod 22 to rotate. While the screw rod 22 moves vertically upward, it drives the pallet 21 to move, thereby driving the stacked battery wafers 01 to gradually move towards the direction of the suction cup 3 for continuous feeding.

[0078] Refer to Figure 9 , a blowing member 23 is arranged on the feeding frame 2, and the blowing member 23 is arranged on the side of the feeding frame 2 for blowing air into the feeding frame 2. During feeding, the blowing member 23 blows air into the feeding frame 2 to blow up the top battery wafer 01, then the suction cup 3 sucks the battery wafer 01, and at the same time, the battery wafer 01 on the suction cup 3 is adjusted through the adjusting member, and then the battery wafer 01 is transferred to the designated position through the suction cup 3 for subsequent printing to improve the printing accuracy.

[0079] Refer to Figure 9 , the blowing member 23 includes a blowing plate 231 and an air pipe 232. The blowing plate 231 is connected to the feeding frame 2, and the blowing plate 231 is arranged in the vertical direction. In this embodiment, this vertical direction is the stacking direction of the battery wafers 01. One end of the air pipe 232 is communicated with the inside of the blowing plate 231, and the other end is connected to an air pump for supplying air to the inside of the blowing plate 231. Air holes 233 are arranged on the side of the blowing plate 231 close to the inside of the feeding frame 2, the air holes 233 are arranged towards the battery wafers 01, and a plurality of air holes 233 are arranged along the length direction of the blowing plate 231, and the plurality of air holes 233 are arranged at intervals on the blowing plate 231. During feeding, the gas in the air pipe 232 blows air into the feeding frame 2 through the blowing plate 231 and the air holes 233, separating two adjacent battery wafers 01 while blowing up the battery wafers 01, so that the suction cup 3 can suck a single battery wafer 01. At the same time, a plurality of air holes 233 are arranged to increase the contact area between the blown gas and the battery wafers 01 for the separation of the battery wafers 01.

[0080] In this embodiment, two groups of blowing members 23 are arranged, and the two groups of blowing members 23 are respectively arranged on both sides of the feeding frame 2. By arranging two groups of blowing members 23 to blow air on the battery wafers 01 at the same time, the force on the battery wafers 01 is more uniform to improve the separation effect of the battery wafers 01. In addition, the number of the blowing members 23 can be adaptively adjusted according to the size of the battery wafers 01 or other feeding requirements.

[0081] The implementation principle of the present invention is:

[0082] Two sets of drivers 7 work synchronously to drive two control rings 81 to move synchronously. During the process, the moving directions of the two control rings 81 are opposite. That is, when one control ring 81 moves downward, the other control ring 81 moves upward. Thus, when the pushing wheel 51 and the correction plate 61 in the first adjustment device 41 approach the solar cell 01 synchronously, the pushing wheel 51 and the correction plate 61 in the second adjustment device 42 move away from the solar cell 01 synchronously; or when the pushing wheel 51 and the correction plate 61 in the first adjustment device 41 move away from the solar cell 01 synchronously, the pushing wheel 51 and the correction plate 61 in the second adjustment device 42 move away from the solar cell 01 synchronously.

[0083] Specifically, the stroke of the pushing wheel 51 has a lower position for pushing the solar cell 01 downward to leave the adsorption surface at the lower end of the suction cup 3 and an upper position for retracting into the opening 34; the strokes of the two correction plates 61 have a correction position for approaching each other to push the solar cell 01 to align with the center of the adsorption surface of the suction cup 3 and a separation position for moving away from the solar cell 01; the pushing wheel 51 in the upper position and the correction plate 61 in the correction position reach the position synchronously, and the pushing wheel 51 in the lower position and the correction plate 61 in the separation position reach the position synchronously.

[0084] The strokes of the pushing wheel 51 of the first adjustment device 41 and the pushing wheel 51 of the second adjustment device 42 are synchronous but the moving directions are opposite. The strokes of the correction plate 61 of the first adjustment device 41 and the correction plate 61 of the second adjustment device 42 are synchronous but the moving directions are perpendicular, so that the pushing wheel 51 of the first adjustment device 41 can cooperate with the correction position stroke of the correction plate 61 of the first adjustment device 41 during the lower position stroke; the correction plate 61 of the first adjustment device 41 and the correction plate 61 in the second adjustment device 42 are alternately in the correction position and abut against the side surface of the solar cell 01 to drive the solar cell 01 to move to the center of the suction cup 3.

[0085] During specific adjustment, after the suction cup 3 adsorbs the solar cell 01, the driver 7 in the first adjustment device 41 drives the control ring 81 in the first adjustment device 41 to move downward. The pushing wheel 51 in the first adjustment device 41 moves downward with the control ring 81 and protrudes from the opening 34 until it pushes the solar cell 01 downward, causing a part of the solar cell 01 to be separated from the adsorption surface of the suction cup 3.

[0086] Then, the driver 7 in the second adjustment device 42 drives the control ring 81 in the second adjustment device 42 to move in a direction away from the suction cup 3. The elastic telescopic rod 621 expands and elongates. The pushing wheel 51 in the second adjustment device 42 remains in the opening 34. At the same time, through the push rod 82, a pair of correction plates 61 in the first adjustment device 41 are driven to move towards the solar cell 01. The correction plates 61 move to cooperate with the side surface of the solar cell 01. At the same time, the pushing wheel 51 rotates until both correction plates 61 cooperate with the side surface of the solar cell 01, completing the adjustment of the solar cell 01 in this direction.

[0087] Then repeat the above operations. The drivers 7 in the first adjusting device 41 and the drivers 7 in the second adjusting device 42 drive the corresponding control rings 81 to move in opposite directions respectively, adjust the position of the solar cell 01 in the other direction, make the center of the solar cell 01 correspond to the center of the suction cup 3, so as to eliminate the deviation when the suction cup 3 adsorbs the solar cell 01, place the solar cell 01 at the specified position, and improve the printing accuracy.

[0088] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
