Description

Technical Field

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

[0002] Photovoltaic cell modules are photovoltaic components, in which photovoltaic cells are the core components of photovoltaic cell modules. Photovoltaic cells are the smallest functional unit of photovoltaic power generation, responsible for converting light energy into electrical energy, and their substrate is silicon wafers. During production, conductive silver paste and other materials are accurately printed on silicon wafers through screen printing technology to form the positive and negative electrodes of the battery. This process is crucial to the conductivity and conversion efficiency of solar cells. When printing the cells, the cells need to be stacked in a feed frame and fed to the printing equipment through the feed frame for subsequent processing.

[0003] The patent application document with publication number CN109305557A discloses a loading device for battery cell production, including a vacuum suction cup arranged above a placement basket. The battery cells are stacked and placed in the placement basket. The vacuum suction cup sucks the battery cells from the placement basket and moves to load the battery cells.

[0004] The above-mentioned loading device also includes a fixed seat, and support seats are installed on both sides of the top outer wall of the fixed seat by bolts, and a ventilation seat is installed on the top outer wall of the support seat by bolts. A ventilation hole is opened in the middle position of the top outer wall of the ventilation seat, and air is blown to the battery cells through the ventilation hole to blow up the top battery cells to prevent the vacuum suction cup from sucking up multiple battery cells at the same time, and then the battery cells are sucked up by the vacuum suction cup for feeding.

[0005] However, this solution still has the following problems: when the top battery cell is blown up in order to absorb the topmost battery cell, the battery cell will shake while being separated from the remaining battery cells. Therefore, the position of the separated battery cell will change. At the same time, the position of the battery cell relative to the vacuum suction cup will also change, causing the suction cup to easily have positioning deviations when absorbing the battery cell, 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 positioning deviation of battery cells during loading in the related art.

[0007] The conveying device for battery module production of the present invention comprises a suction cup for sucking battery sheets, and the suction cup is provided with a first and a second adjusting device around its center, and the first and the second adjusting device each comprise a push-off assembly, a correction assembly, a driver and a transmission assembly; 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; 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; 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.

[0008] 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.

[0009] 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; 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.

[0010] The effect is that by configuring a transmission component connected to the placement rack and the mounting rack, the driver can drive the placement rack to move through the transmission component, and the placement rack moves toward the outside of the opening, and the position of the push wheel is adjusted to drive the battery cell to separate from the suction cup through the push wheel, and then perform subsequent adjustments. The transmission component drives the correction plate to move through the mounting rack, so that the correction plate is close to or away from the battery cell, thereby realizing the control of the position of the push wheel and the correction plate.

[0011] Preferably, the transmission assembly includes a control ring mounted on the upper end of the suction cup for vertical movement, a push rod connected to the mounting frame, and a connecting rod connected to the placement frame; The two ends of the push rod are respectively rotatably matched with the mounting frame and the control ring, the push rod is tilted, the connecting rod extends to the upper end of the suction cup and is connected to the control ring, and the output end of the driver is connected to the control ring; The driver drives the control ring to move up and down, and the movement of the control ring drives the push wheel to move through the connecting rod and the placement frame, and at the same time, the rotation of the push rod drives the installation frame and the correction plate to move.

[0012] The effect is that the driver drives the control ring to move, and the movement of the control ring drives the installation frame to move through the push rod, and at the same time drives the placement frame to move through the connecting rod, thereby adjusting the position of the correction plate and the push wheel.

[0013] Preferably, the transmission assembly in the first adjusting device is respectively connected to the push wheel in the first adjusting device and the correction plate in the second adjusting device, and the transmission assembly in the second adjusting device is respectively connected to the push wheel in the second adjusting device and the correction plate in the first adjusting device, and the end of the push rod connected to the mounting frame is arranged to be inclined toward the direction of the suction cup, so that when the push wheel in the first / second adjusting device moves to push the battery cell, the correction plate in the second / first adjusting device moves away from the battery cell.

[0014] The effect is that the two control rings move in opposite directions, driving the same set of push wheels and correction plates to move, and correcting the battery cells. The two control rings move in opposite directions alternately, so that the two sets of push wheels and correction plates can adjust the battery cells alternately. The push wheels can be controlled to push the battery cells away from the suction cups, and then the correction plates can be used to adjust the position of the battery cells.

[0015] Preferably, the mounting frame comprises an elastic telescopic rod, which is arranged along the sliding direction of the correction plate, and the correction plate is connected to the elastic telescopic rod.

[0016] The effect is that when the correction plate abuts against the battery cell, the elastic telescopic rod can undergo elastic deformation, thereby reducing hard contact between the correction plate and the battery cell and protecting the battery cell.

[0017] 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 in the sleeve rod, the inner rod is connected to the placement frame, and a spring connected to the inner rod is arranged in the sleeve rod, so that when the correction plate in the first / second adjustment device moves close to the battery cell, the inner rod slides relative to the sleeve rod, and the push wheel in the second / first adjustment device is in the opening.

[0018] The effect is that when the control ring drives the correction plate to move toward the battery cell, the inner rod corresponding to the control ring slides in the sleeve rod, and the placement frame and the push wheel are in the opening, reducing the phenomenon of the placement frame interfering with the movement of the control ring. In addition, a spring is arranged between the inner rod and the sleeve rod to reduce the phenomenon of hard contact between the push wheel and the battery cell, reduce damage to the battery cell, and protect the battery cell.

[0019] Preferably, each group of pushing-off components comprises at least two pushing wheels, the rotation axes of the plurality of pushing wheels are parallel to each other, and the plurality of pushing wheels abut against a plurality of locations on the battery sheet to drive the battery sheet to separate from the suction cup.

[0020] The effect is that multiple push wheels are provided to increase the force-bearing area after the battery cell is separated from the suction cup, thereby improving the stability of the battery cell when moving. At the same time, it can reduce the phenomenon of battery cell being damaged due to excessive local force.

[0021] Preferably, a plurality of rubber rings are coaxially sleeved outside the push wheel, and the plurality of rubber rings are spaced apart on the push wheel along the axial direction thereof.

[0022] The effect is that the rubber ring contacts the battery cell, increasing the friction between the battery cell and the push wheel. At the same time, the movement of the battery cell drives the push wheel to rotate. Under the action of the rubber ring, the movement of the battery cell in the direction away from the rotation direction of the push wheel is reduced, so that the battery cell can be adjusted to the specified position.

[0023] Preferably, an extension frame and an extension rod are provided on the side of the control ring, the push rod is connected to the connecting frame, the connecting rod is connected to the extension rod, and the extension frame and the extension rod on another control ring are arranged along the sliding direction of the control ring.

[0024] The effect is that the extension frame and the extension rod are provided to reduce the interference between the push rod and the connecting rod on another control ring, so that the overall structure can operate stably.

[0025] Beneficial effects: 1. When feeding, the suction cup absorbs the battery cell. After the suction cup absorbs the battery cell, the battery cell is moved by the push wheel and the correction plate. At the same time, the battery cell is moved in another vertical direction under the action of another set of push wheels and the correction plate. The two sets of push wheels and the correction plate adjust the position of the battery cell alternately, and adjust the battery cell to correspond to the center of the suction cup to eliminate the deviation when the suction cup absorbs the battery cell, so as to facilitate the placement of the battery cell in the specified position and improve the subsequent printing accuracy.

[0026] 2. The push wheels and correction plates in each set of adjustment parts are connected to two control rings respectively. When correcting the battery cell, the push wheels and correction plates in the two sets of adjustment devices work synchronously, driving the corresponding push wheels to move and cooperate with the battery cell, and the corresponding correction plates move toward the battery cell. When the driver drives the control ring to move in the opposite direction, the position of the battery cell in another vertical direction is adjusted so as to adjust the battery cell to the specified position. During adjustment, the control ring moves to drive the push wheel to move, and the push wheel pushes the battery cell to separate from the suction cup. The other control ring can continuously drive the correction plate to move until the battery cell is adjusted to the specified position. This setting makes the movement of the correction plate larger and improves the adjustment effect on the battery cell.

[0027] 3. The two groups of control rings move synchronously in opposite directions, driving the push wheel to push the battery cell while the other correction plate moves away from the battery cell. The inner rod corresponding to the other push wheel slides in the sleeve rod, and the push wheel remains stationary in the opening, reducing the phenomenon of the push wheel interfering with the movement of the battery cell, so that the two groups of push wheels and the correction plate can adjust the position of the battery cell alternately.

[0038] 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.

[0039] Reference Figure 1 The conveying device for battery module production of the present invention (hereinafter referred to as the feeding device) is installed on one side of the printing device 1 when in use.

[0040] Reference Figure 2 and Figure 3 The feeding device includes a frame 11, a feeding frame 2, a transfer mechanism, a suction cup 3, and an adjustment device. The feeding frame 2 is used to stack 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 feeding frame 2 and the printing device 1. The transfer mechanism includes a horizontal guide rail extending left and right, a trolley moving left and right on the horizontal guide rail, and a lifting arm connected to the bottom of the trolley. Figures 1 to 3 The suction cup 3 is installed at the lower end of the lifting arm of the transfer mechanism, and the adsorption surface of the suction cup 3 is downward and toward the discharge frame 2.

[0041] When the feeding device is working, the suction cup 3 absorbs the battery cell 01, and the transfer mechanism drives the suction cup 3 to move to the printing device 1. After the battery cell 01 is placed on the printing device 1, the feeding operation of a single battery cell 01 is completed, and the above actions are repeated to continuously feed the battery cell 01.

[0042] Reference Figures 3 to 5The adjusting device is installed on the suction cup 3. The adjusting device is provided with two groups corresponding to the two pairs of sides of the rectangular battery cell 01, which are respectively: the first adjusting device 41 for adjusting the position of the battery cell 01 front and back, and the second adjusting device 42 for adjusting the position of the battery cell 01 left and right. The first adjusting device 41 is arranged corresponding to the front and back sides of the battery cell 01, and the second adjusting device 42 is arranged corresponding to the left and right sides of the battery cell 01. The first adjusting device 41 and the second adjusting device 42 are used to adjust the position of the battery cell 01 in alignment. Here, alignment refers to the central axis of the adsorption surface of the suction cup 3. That is, the positions of the front and back sides and the left and right sides of the battery cell 01 are pushed and adjusted by the first adjusting device 41 and the second adjusting device 42 in turn, so that the center of the battery cell 01 corresponds to the center of the suction cup 3, so as to eliminate the deviation when the suction cup 3 adsorbs the battery cell 01 and improve the subsequent printing accuracy.

[0043] 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 The first adjusting device 41 is described.

[0044] Reference Figures 3 to 8 The first adjusting device 41 includes a pushing component 5, a correction component 6, a driver 7 and a transmission component 8. The driver 7 is connected to the pushing component 5 and the correction component 6 through the transmission component 8 and controls the two. The pushing component 5 cooperates with the upper surface of the battery cell 01 to push the battery cell 01 to separate from the adsorption surface of the suction cup 3. The correction component 6 cooperates with two opposite side surfaces of the battery cell 01 to correct the position of the battery cell 01 by pushing the battery cell 01 in the horizontal direction, thereby adjusting the position of the battery cell 01.

[0045] Reference Figure 5 and Figure 6 The push-off assembly 5 includes a push wheel 51 and a placement frame 52 for mounting the push wheel 51. The push wheel 51 is rotatably arranged on the placement frame 52. An opening 34 is provided at the lower end of the suction cup 3. The placement frame 52 slides in the opening 34 in a direction perpendicular to the adsorption surface. The placement frame 52 moves in the opening 34 while driving the push wheel 51 to move. The transmission assembly 8 is connected to the placement frame 52. The driver 7 adjusts the position of the placement frame 52 through the transmission assembly 8.

[0046] Reference Figure 3 and Figure 5Each set of push-off components 5 includes two push wheels 51, which are symmetrically arranged around the center of the suction cup 3, and the rotation axes of the two push wheels 51 are parallel to each other. When the push wheels 51 cooperate with the battery cell 01, the contact area with the battery cell 01 is increased, thereby improving the stability of the battery cell 01. At the same time, the two push wheels 51 are evenly separated on the suction cup 3, so that the battery cell 01 is evenly stressed, so as to adjust the battery cell 01 to a specified position. In addition, the number of push wheels 51 can be adaptively adjusted according to the size of the battery cell 01, which can further improve the stability of the battery cell 01 when it is separated from the suction cup 3. In addition, by having multiple push wheels 51 contacting the battery cell 01 at the same time, the deformation of the battery cell 01 when it is separated from the suction cup 3 is reduced, and the battery cell 01 can be protected while correcting the position of the battery cell 01.

[0047] In the initial state, the push wheel 51 is in the opening 34, the suction cup 3 sucks the battery cell 01 from the discharge frame 2, the battery cell 01 abuts against the adsorption surface, the placement frame 52 moves to drive the push wheel 51 to move downward to the outside of the opening 34 and cooperate with the battery cell 01, the push wheel 51 drives the battery cell 01 to separate from the suction cup 3 and maintains an abutting state with the battery cell 01, so that there is a certain gap between the battery cell 01 and the adsorption surface, and then the position of the battery cell 01 is adjusted by the correction component 6, and the position of the battery cell 01 is adjusted in cooperation with the correction component 6. When the battery cell 01 moves, the push wheel 51 rotates accordingly to reduce the friction force on the battery cell 01 when it moves, which is convenient for adjusting the position of the battery cell 01 and reducing the phenomenon of damage to the battery cell 01.

[0048] After the push wheel 51 drives the battery cell 01 to separate from the adsorption surface of the suction cup 3, the gap between the battery cell 01 and the suction cup 3 is smaller, and the suction nozzle on the suction cup 3 is continuously in a negative pressure state during the feeding process, so that the battery cell 01 can still be indirectly adsorbed on the suction cup 3, reducing the phenomenon of the battery cell 01 falling off the suction cup 3 when the battery cell 01 is pushed to separate from the suction cup 3.

[0049] Reference Figure 8 A rubber ring 9 is provided on the side of the push wheel 51. There are multiple rubber rings 9, and the multiple rubber rings 9 are arranged at intervals along the length direction of the push wheel 51, that is, the push wheel 51 contacts the battery cell 01 through the rubber ring 9, reducing the damage to the battery cell 01. At the same time, the rubber ring 9 increases the friction between the battery cell 01 and the push wheel 51, so that the battery cell 01 can move with the rotation direction of the push wheel 51, reducing the deviation of the battery cell 01 during the movement, so as to adjust the battery cell 01 to a specified position.

[0050] Reference 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] Reference Figure 5 and Figure 6 The transmission assembly 8 in the first adjusting device 41 is 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 assembly 8 in the second adjusting device 42 is respectively connected to the correction plate 61 in the first adjusting device 41 and the push wheel 51 in the second adjusting device 42.

[0056] Specifically, the control ring 81 in the first adjusting device 41 drives the push wheel 51 in the first adjusting device 41 and the correction plate 61 in the second adjusting device 42 to move synchronously, and the control ring 81 in the second adjusting device 42 drives the correction plate 61 in the first adjusting device 41 and the push wheel 51 in the second adjusting device 42 to move synchronously. That is, the two control rings 81 work 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.

[0057] Specifically, the control ring 81 in the first adjustment device 41 moves downward to drive the push wheel 51 in the first adjustment device 41 to move downward to push the battery cell 01, and the control ring 81 in the second adjustment device 42 moves upward to drive the correction plate 61 in the first adjustment device 41 to move toward the battery cell 01. The action of the control ring 81 in this process is defined as forward movement; the control ring 81 in the second adjustment device 42 moves downward to drive the push wheel 51 in the second adjustment device 42 to push the battery cell 01, and the control ring 81 in the first adjustment device 41 moves downward to drive the correction plate 61 in the second adjustment device 42 to move toward the battery cell 01. The action of the control ring 81 in this process is defined as reverse movement. That is, the two drivers 7 synchronously drive the corresponding control ring 81 to move forward and reverse successively to achieve correction and adjustment of the battery cell 01 in the front-back and left-right directions.

[0058] Reference Figure 5 and Figure 6 An extension frame 811 and an extension rod 812 are arranged on the side of the control ring 81, the push rod 82 is connected to the extension frame 811, the connecting rod 521 is connected to the extension rod 812, the extension frame 811 and the extension rod 812 on the other 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 away from the suction cup 3. By setting the extension frame 811 and the extension rod 812, the mutual interference between the two sets of connecting rods 521 and the push rod 82 during movement is reduced, and the overall stability is improved.

[0059] Reference Figure 5 and Figure 8The 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 in the sleeve rod 522. The inner rod 523 is connected to the placement frame 52. An elastic member 524 is arranged in 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 toward the battery cell 01, the control ring 81 pulls the sleeve rod 522. At this time, the push wheel 51 is in the opening 34, and the inner rod 523 slides in the sleeve rod 522, reducing the phenomenon that the connecting rod 521 interferes with the movement of another group of correction plates 61. In addition, an elastic member 524 is provided inside 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 push wheel 51 from making hard contact with the battery cell 01, thereby preventing the surface of the battery cell 01 from being damaged due to excessive force in an instant, thereby protecting the battery cell 01.

[0060] The suction cup 3 is provided with a slide seat 1 32 and a slide seat 2 33, the mounting frame 62 is slidably matched with the slide seat 1 32, and the sleeve rod 522 is slidably matched with the slide seat 2 33, that is, the sleeve rod 522 is slidably arranged on the suction cup 3 through the slide seat 2 33. By providing the slide seat 1 32 and the slide seat 2 33, the stability of the sleeve rod 522 and the mounting frame 62 when moving is improved.

[0061] 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.

[0062] The rotation axes of the push wheel 51 in the first adjustment device 41 and the push wheel 51 in 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 respectively adjust the battery cell 01 along two perpendicular directions to achieve centering adjustment of the battery cell 01.

[0063] In addition, a sensing element is provided on the elastic telescopic rod 621, and a controller is provided on the suction cup 3. The sensing element is electrically connected to the signal receiving end of the controller. The sensing element is provided as an infrared sensor. The control end of the controller is electrically connected to the switch of the driver 7 for controlling the driver 7. The sensing element is used to detect the expansion and contraction amount of the elastic telescopic rod 621. By providing two correction plates 61 in both the first adjustment device 41 and the second adjustment device 42, after the correction plate 61 corrects the position of the battery cell 01, the deformation amount of the elastic telescopic rod 621 is the same, that is, the expansion and contraction amount of the elastic telescopic rod 621 is the same.

[0064] When the correction plate 61 corrects the battery cell 01, the sensing component detects the extension and contraction amount of the elastic telescopic rod 621. After each correction action of the correction plate 61, the sensing component sends a signal of the extension and contraction amount of the elastic telescopic rod 621 to the controller, and the controller determines the extension and contraction amount of the two elastic telescopic rods 621.

[0065] If the two elastic telescopic rods 621 have different telescopic amounts, that is, there is a difference in the telescopic amounts, that is, the battery cell 01 has not been calibrated in that direction, the driver 7 will continue to work and repeatedly drive the calibration plate 61 to adjust the battery cell. That is, in the 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.

[0066] If the expansion and contraction amounts of the two elastic telescopic rods 621 are the same, that is, there is no difference in the expansion and contraction amounts of the two elastic telescopic rods 621, it is determined that the correction of the battery cell 01 in this direction is completed. And if the expansion and contraction amounts of the elastic telescopic rods 621 corresponding to the other set of correction plates 61 are also the same, it is considered that the correction of the battery cell 01 in another vertical direction is also completed. At this time, the controller controls the driver 7 to stop working, and the correction of the battery cell 01 is completed.

[0067] A visual sensor is provided on the suction cup 3, and the signal output end of the visual sensor is electrically connected to the signal receiving end of the controller. The visual sensor has two detection modes, one is to detect whether there is a deviation in the position of the battery cell 01 when the battery 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 battery cell 01 relative to the suction cup 3 after the battery cell 01 is adsorbed on the suction cup 3. In both detection modes, after the position deviation of the battery cell 01 is detected and the battery cell 01 is adsorbed on the suction cup 3, the controller controls the driver 7 to start and correct the position of the battery cell 01. If both detection modes are not met, it is deemed that the suction cup 3 has no deviation when adsorbing the battery cell 01, and the driver 7 does not work after the suction cup 3 adsorbs the battery cell 01, that is, the correction plate 61 is stationary, and the push wheel 51 is in the opening 34, and it is normally transported and fed.

[0068] In this embodiment, the transfer mechanism is configured as a cylinder, which is disposed above the material discharging frame 2, and the output end of the cylinder is connected to the suction cup 3 and its output end faces the printing device 1. The suction cup 3 is driven by the cylinder to move back and forth between the material discharging frame 2 and the printing device 1, so as to continuously transfer the battery cells 01 in the material discharging frame 2 to the printing device 1.

[0069] Reference Fig. 9A support plate 21 is provided in the material discharging frame 2, and a screw rod 22 is rotatably provided on the frame 11. The end of the screw rod 22 is connected to the support plate 21, and a motor can be provided at the other end of the screw rod 22. The screw rod 22 is threadedly connected to the frame 11. The battery cells 01 are stacked and placed on the support plate 21. With continuous feeding, the motor drives the screw rod 22 to rotate, and the screw rod 22 moves vertically upward while driving the support plate 21 to move, thereby driving the stacked battery cells 01 to gradually move toward the direction of the suction cup 3 for continuous feeding.

[0070] Reference Fig. 9 The discharge frame 2 is provided with a blowing member 23, which is arranged on the side of the discharge frame 2 and is used to blow air into the discharge frame 2. When feeding, the blowing member 23 blows air into the discharge frame 2 to blow up the battery cell 01 on the top, and then the suction cup 3 sucks the battery cell 01, and at the same time adjusts the battery cell 01 on the suction cup 3 through the adjusting member, and then transfers the battery cell 01 to the designated position through the suction cup 3 for subsequent printing to improve printing accuracy.

[0071] Reference Fig. 9 The blowing member 23 includes a blowing plate 231 and an air pipe 232. The blowing plate 231 is connected to the discharge frame 2, and the blowing plate 231 is arranged in a vertical direction. In this embodiment, the vertical direction is the stacking direction of the battery cells 01. One end of the air pipe 232 is connected to the inside of the blowing plate 231, and the other end is connected to the air pump for supplying air to the inside of the blowing plate 231. An air hole 233 is arranged on one side of the blowing plate 231 close to the inside of the discharge frame 2. The air hole 233 is arranged toward the battery cell 01. There are multiple air holes 233 along the length direction of the blowing plate 231, and the multiple air holes 233 are arranged at intervals on the blowing plate 231. When loading, the gas in the air pipe 232 blows into the discharge frame 2 through the blowing plate 231 and the air hole 233, and separates two adjacent battery cells 01 while blowing up the battery cell 01, so that the suction cup 3 can absorb a single battery cell 01. At the same time, a plurality of air holes 233 are provided to increase the contact area between the blown gas and the battery cell 01 so as to facilitate separation of the battery cell 01 .

[0072] In this embodiment, two groups of blowing members 23 are provided, and the two groups of blowing members 23 are respectively provided on both sides of the discharge frame 2. By providing two groups of blowing members 23 to blow air to the battery cell 01 at the same time, the force on the battery cell 01 is made more uniform, so as to improve the separation effect of the battery cell 01. In addition, the number of blowing members 23 can be adaptively adjusted according to the size of the battery cell 01 or other feeding requirements.

[0073] The implementation principle of the present invention is: The two groups of drivers 7 work synchronously, driving the 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, thereby achieving that when the push wheel 51 and the correction plate 61 in the first adjustment device 41 synchronously approach the battery cell 01, the push wheel 51 and the correction plate 61 in the second adjustment device 42 synchronously move away from the battery cell 01; or when the push wheel 51 and the correction plate 61 in the first adjustment device 41 synchronously move away from the battery cell 01, the push wheel 51 and the correction plate 61 in the second adjustment device 42 synchronously move away from the battery cell 01.

[0074] Specifically, the travel of the push wheel 51 includes a lower position for pushing the battery cell 01 downward to leave the adsorption surface of the lower end of the suction cup 3, and an upper position for receiving the battery cell 01 into the opening 34; the travel of the two correction plates 61 includes a correction position for pushing the battery cell 01 close to each other to align with the center of the adsorption surface of the suction cup 3, and a disengagement position for moving away from the battery cell 01; the push wheel 51 in the upper position is synchronized with the correction plate 61 in the correction position to reach the position, and the push wheel 51 in the lower position is synchronized with the correction plate 61 in the disengagement position to reach the position.

[0075] The push wheel 51 of the first adjusting device 41 and the push wheel 51 of the second adjusting device 42 have synchronous strokes but opposite movement directions; the correction plate 61 of the first adjusting device 41 and the correction plate 61 of the second adjusting device 42 have synchronous strokes but perpendicular movement directions, so that the push wheel 51 of the first adjusting device 41 can cooperate with the correction position stroke of the correction plate 61 of the first adjusting device 41 during the lower stroke; the correction plate 61 of the first adjusting device 41 and the correction plate 61 in the second adjusting device 42 are alternately in the correction position and abut against the side of the battery cell 01 to drive the battery cell 01 to move to the center of the suction cup 3.

[0076] During specific adjustment, after the suction cup 3 adsorbs the battery 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, and the push 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 battery cell 01 downward, so that a part of the battery cell 01 is separated from the adsorption surface of the suction cup 3.

[0077] Then the driver 7 in the second adjusting device 42 drives the control ring 81 in the second adjusting device 42 to move in the direction away from the suction cup 3, the elastic telescopic rod 621 is extended and lengthened, and the push wheel 51 in the second adjusting device 42 remains in the opening 34. At the same time, the push rod 82 drives a pair of correction plates 61 in the first adjusting device 41 to move toward the battery cell 01, and the correction plates 61 move to cooperate with the side of the battery cell 01. At the same time, the push wheel 51 rotates until the two correction plates 61 cooperate with the side of the battery cell 01, thereby completing the adjustment of the battery cell 01 in this direction.

[0078] Then repeat the above operation, the driver 7 in the first adjustment device 41 and the driver 7 in the second adjustment device 42 respectively drive the corresponding control ring 81 to move in opposite directions, adjust the position of the battery cell 01 in the other direction, and make the center of the battery cell 01 correspond to the center of the suction cup 3 to eliminate the deviation when the suction cup 3 adsorbs the battery cell 01, place the battery cell 01 at the specified position, and improve the printing accuracy.

[0079] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
