[0059] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments. Example

[0060] The present invention provides a device for selecting high-quality battery plates, such as Figure 1-Figure 4 As shown, it includes two screening lines arranged side by side on the same assembly line stand. The screening line includes an input unit 01, a leveling unit 59, a transmission transition unit 03, a sorting unit 04 and an output unit 05 which are connected in sequence along the length direction of the stand. The input unit 01 is used to import battery plates (hereinafter referred to as electrode plates), which are in the form of sheets and are placed upright on the input unit 01. The leveling unit 59 is a sheet leveling unit, which is used to level the upright electrode plates so as to lay them flat on the transmission transition unit 03. It should be noted that the processed electrode plates are generally stacked together. In order to realize automated production, the present invention is designed to stack the stacked electrode plates flat on the input unit 01, that is, each electrode plate is placed upright on the input unit 01. The transmission transition unit 03 is used to transport the leveled electrode plates to the sorting unit 04. The sorting unit 04 is used to remove defective plates. The output unit 05 is used to export good plates. In addition, the screening line of the present invention is provided with a control box 41 and a human-machine interaction screen 42. The control box 41 is arranged below the stand. The box shell of the control box 41 is formed by a sealed box plate arranged on the side of the stand corresponding to the position of the transmission transition unit 03. Therefore, the control box 41 and the stand are an integrated structure. The human-machine interaction screen 42 can be arranged at any position that is convenient for the staff to operate and use. In this embodiment, the human-machine interaction screen 42 is erected on the stand and is located in the transmission transition unit 03. The control box 41 is equipped with an automatic control system. The automatic control system is provided with a programmed program designed according to the actual production situation, which is a common method in the industry and will not be described in detail here. The human-machine interaction screen 42 is electrically connected to the control system.

[0061] In the present invention, the conveying direction of the electrode plate is taken as the front, and the direction opposite to the conveying direction is taken as the rear. The input unit 01 includes a plurality of conveying chains 15 arranged side by side along the width direction of the platform and a motor connected to the conveying chain 15 by transmission. Each conveying chain 15 is arranged along the length direction of the platform. Each conveying chain 15 is respectively sleeved on two first gears located at the front and rear ends of the input unit 01, and the conveying chain 15 is meshed with the first gear. Several first gears located at the front end are respectively tightly sleeved on the first rotating shaft, and several first gears located at the rear end are respectively tightly sleeved on the second rotating shaft. The first rotating shaft and the second rotating shaft are respectively mounted on the platform along the width direction of the platform, and the installation height of the first rotating shaft is higher than the installation height of the second rotating shaft, so that the conveying chain 15 is arranged to climb forward in an inclined manner. The inclination angle is preferably 10°. The input end of the first rotating shaft is sleeved with a second gear, the output end of the motor is sleeved with a third gear, a transmission chain is sleeved between the second gear and the third gear, and the transmission chain is respectively meshed with the second gear and the third gear. The motor drives the third gear to rotate, and the third gear drives the second gear to rotate synchronously through the transmission of the transmission chain. The second gear drives the first rotating shaft to rotate, and then the first rotating shaft drives the first gear fixed thereon to rotate, and finally the first gear drives the conveying chain 15 to rotate and convey the electrode plate forward. The electrode plate is erected on the conveying chain 15, and several electrode plates are neatly arranged along the length direction of the stand. The conveying chain 15 is equipped with a magnet block (not shown in the figure), and the electrode plates are arranged in several columns, and the magnet block is set on the electrode plate at the rear end of each column.

[0062] The output end of the input unit 01 has a support plate 16 arranged along the width direction of the platform, and the support plate 16 is smoothly connected with the output end of each conveying chain 15. The height of the support surface of the support plate 16 is higher than the height of the conveyor belt of the transmission transition unit 03, forming a height difference, which facilitates the free fall of the electrode plate in the subsequent sequence.

[0063] The leveling unit 59 includes a leveling mechanism, which includes a mounting seat 43, a driving device, a first transmission shaft 45, a second transmission shaft 48, a transmission belt 49, a vacuum suction head 46, a first position sensor and a second position sensor. The driving device is preferably a servo motor 44. The mounting seat 43 is mounted on the transmission transition unit 03, and the mounting seat 43 is connected to the output end of the input unit 01. In this embodiment, the two screening lines share the same mounting seat 43. The mounting seat 43 has a mounting plate 47. The servo motor 44 is mounted on the mounting plate 47, and the servo motor 44 is relatively located between the two screening lines. The output shaft of the servo motor 44 is installed along the width direction of the stand, and the axial ends of the output shaft of the servo motor 44 are respectively facing the two screening lines. The two screening lines are respectively provided with a first transmission shaft 45. The two first transmission shafts 45 are respectively connected to the axial ends of the output shaft of the servo motor 44 through a coupler. The first transmission shaft 45 is separated from the output shaft of the servo motor 44. The coupler is a ring sleeve, which can be sleeved on the output shaft and / or the first transmission shaft 45. When in use, the coupler is sleeved on the output shaft and the first transmission shaft 45 by bolts and nuts to play a joint role. When not in use, the coupler can be sleeved on the output shaft of the servo motor 44 or the first transmission shaft 45, and the output shaft of the servo motor 44 and the first transmission shaft 45 are in a separated state. In this way, the two screening lines can work synchronously or independently.

[0064] The first transmission shaft 45 is arranged in parallel with the second transmission shaft 48. The first transmission shaft 45 is installed on the top of the mounting plate 47 through a bearing seat, and the second transmission shaft 48 is installed on the bottom of the mounting plate 47 through another bearing seat. In this embodiment, two second transmission shafts 48 are provided corresponding to the two first transmission shafts 45. The transmission belt 49 is sleeved on the first transmission shaft 45 and the second transmission shaft 48 located on the same screening line. The lower surface of the mounting plate 47 is provided with slide rails 53 corresponding to the axial ends of the second transmission shaft 48, and the slide rails 53 are arranged along the length direction of the platform, that is, the slide rails 53 are arranged perpendicular to the second transmission shaft 48, and the two slide rails 53 are arranged in parallel. The slide rails 54 are movably mounted on the slide rails 53, and the axial ends of the second transmission shaft 48 are respectively connected to a group of relatively arranged slide rails 54 through a movable rod group. The vacuum suction head 46 is installed on the fixed plate, and the fixed plate is connected to the slide rail 54 through a connecting rod 60. Therefore, the vacuum suction head 46 is movably installed on the mounting plate 47 through the cooperation of the slide rails 53 and the slide rails 54. The connecting rod 60 is arranged perpendicularly to the slide rail 53. The vacuum suction head 46 is arranged in alignment with the vertically placed electrode plate. Preferably, the vacuum suction head 46 corresponds to the middle part or the middle bottom of the electrode plate.

[0065] In this embodiment, four vacuum suction heads 46 are provided on the fixed plate. The vacuum suction heads 46 are used to suck the electrode plate. The four vacuum suction heads 46 are provided to form four suction points, which increases the suction force and the probability that defective boards with local gaps or small through holes can be sucked and leveled normally. The vacuum suction heads 46 are connected to the vacuum generator.

[0066] The movable rod group includes a first movable rod 50 and a second movable rod 51, one end of the first movable rod 50 is hinged to the second transmission shaft 48, and the other end of the first movable rod 50 is hinged to the second movable rod 51. The other end of the second movable rod 51 is hinged to the slider 54. Therefore, the servo motor 44 is connected to the slider 54, that is, the servo motor 44 drives the first transmission shaft 45 and the second transmission shaft 48 to rotate synchronously, and then drives the movable rod group to rotate, and then drives the slider 54 to slide on the slide rail 53, and finally the vacuum suction head 46 can be displaced with the sliding of the slider 54.

[0067] The first position sensor is preferably a first magnetic proximity switch. The first magnetic proximity switch is arranged on the lower surface of the mounting plate 47, and the first magnetic proximity switch is used to sense the position change of the vacuum suction head 46. The first magnetic proximity switch is arranged close to the slide rail 53. A first magnetic conductor is fixed on the slider 54, and the first magnetic conductor is preferably an iron sheet, and the iron sheet moves with the slider 54. A sensing area is provided on the first magnetic proximity switch. The first magnetic proximity switch can convert the positional relationship change of the iron sheet relative to the sensing area into an electrical signal. The first magnetic proximity switch is electrically connected to the control system.

[0068] The second position sensor is preferably a second magnetic proximity switch. The second magnetic proximity switch is fixed directly above the support plate 16. The second magnetic proximity switch is used to sense changes in the position of the electrode plate. The second magnetic proximity switch includes a second magnetic conductor and a switch body 55, and a sensing area is provided on the switch body 55. The second magnetic conductor is preferably an iron rod 56. The iron rod 56 is hinged to the switch body 55 by a pin, and the bottom end of the iron rod 56 is aligned with the top of the electrode plate. The pin is located between the top and bottom ends of the iron rod 56. When the iron rod 56 is swung, the top of the iron rod 56 can be relatively located within the sensing area of ​​the switch body 55 or relatively located outside the sensing area of ​​the switch body 55. In this way, the second magnetic proximity switch can convert the change in the positional relationship between the iron rod 56 and the electrode plate into an electrical signal. The switch body 55 is electrically connected to the control system.

[0069] The movable rod groups located at the axial ends of the second transmission shaft 48 are respectively the first movable rod group and the second movable rod group. The servo motor 44 drives the second transmission shaft 48 to rotate, and then the first movable rod group and the second movable rod group move synchronously. And the motion state after the servo motor 44 drives the first movable rod group to rotate 180° in the initial state (that is, the first movable rod 50 and the second movable rod 51 are fully unfolded and in a straight line) is consistent with the initial state of the second movable rod group (that is, the first movable rod 50 completely overlaps with the second movable rod 51), and the two always maintain a staggered 180° motion state in a front-and-back state. In this way, the vacuum suction heads 46 corresponding to the axial ends of the second transmission shaft 48 always maintain a "front-and-back" motion state, which is convenient for staggering in time when sucking the electrode plates, so as to achieve the electrode plates being laid one by one on the transmission transition unit 03, and prevent the electrode plates from being overlapped.

[0070] As a preferred embodiment, the state in which the iron rod 56 is not subjected to external force is taken as the initial state. In the initial state, the top of the iron rod 56 is located in the sensing area of ​​the second magnetic proximity switch, and at this time, the electrode plate is continuously transported forward. Further, when the iron rod 56 is subjected to the squeezing force of the electrode plate transported forward, the bottom end of the iron rod 56 moves forward (that is, the top end of the iron rod 56 moves backward). When the top end of the iron rod 56 moves to the sensing area away from the switch body 55, the control system automatically controls the motor to stop working after receiving the corresponding electrical signal, that is, the conveying chain 15 stops moving, and the iron rod 56 and the electrode plate are both in a stationary state. For the convenience of description, the electrode plate in contact with the iron rod 56 is numbered as plate No. 1, and the electrode plate close to plate No. 1 is numbered as plate No. 2. When the conveying chain 15 stops moving, the servo motor 44 drives the slider 54 to slide on the slide rail 53 through power transmission. When the slider 54 is fixed on the slider 54, the slider 54 is driven by the servo motor 44. When the iron sheet moves backward to pass through the sensing area of ​​the first magnetic proximity switch, the control system controls the control valve between the vacuum suction head 46 and the vacuum generator to open automatically. When the vacuum suction head 46 moves to contact the No. 1 plate, the vacuum suction drives the No. 1 plate to move forward with the vacuum suction head 46. When the iron sheet fixed on the slider 54 moves forward to pass through the sensing area of ​​the first magnetic proximity switch again, the control system controls the control valve between the vacuum suction head 46 and the vacuum generator to close automatically. At this time, the vacuum suction disappears. Due to the action of gravity, the No. 1 plate falls freely using the height difference, and then lays flat on the conveyor belt of the transmission transition unit 03, and the No. 2 plate is still supported on the support plate 16. It should be noted that the moving distance of the slider 54 is affected by the total length of the superposition of the first movable rod 50 and the second movable rod 51, and the moving distance can be adaptively adjusted according to the distance between the electrode plate and the vacuum suction head 46. In addition, the sensing area range of the first magnetic proximity switch and the second magnetic proximity switch can be selected according to actual needs.

[0071] After the vacuum suction head 46 sucks the No. 1 plate, the iron rod 56 immediately resets to the initial position (i.e., the top of the iron rod 56 is located in the sensing area of ​​the second magnetic proximity switch), the control system starts the motor again, and the electrode plate is transported forward again (the distance of each forward movement is the thickness of a single electrode plate), and the above steps are repeated to level the No. 2 plate. It should be noted that the conveying chain 15 is arranged to climb forward in an inclined manner, so that the electrode plate has a backward component force, which prevents the No. 2 plate from tipping forward after the No. 1 plate is sucked by the vacuum suction head 46, etc., and interferes with subsequent operations, and facilitates the leveling operation of the leveling mechanism.

[0072] The transmission transition unit 03 includes a first conveyor belt 18, and a mounting seat 43 is erected above the first conveyor belt 18. The electrode plate is flattened and laid on the first conveyor belt 18. The transmission transition unit 03 is divided into a transition zone and an integration zone in sequence along the conveying direction, and the transition zone is separated into two channels by a baffle. Two groups of vacuum suction heads 46 in the same screening line are set corresponding to the two channels. Integration plates are respectively provided on both sides of the integration zone, and the distance between the two integration plates gradually decreases along the conveying direction, so that it is convenient to integrate the electrode plates from the two channels (i.e., the electrode plates arranged in two columns) into the electrode plates arranged in a single column. The first conveyor belt 18 is driven by a common driving and transmission device, such as a motor and a sprocket chain, so as to drive the first conveyor belt 18 to move.

[0073] The sorting unit 04 includes a slideway 25 arranged to slide forward in an inclined manner, and a computer vision device 26 arranged above the slideway 25 for collecting and analyzing images of the electrode plates to distinguish between good and bad products.

[0074] The computer vision device 26 includes a support frame 27, a base plate 28, a video sensor, a computer control module and a video display screen 40. The support frame 27 is tilted and erected above the slide 25, and the base plate 28 is connected to the output end of the first conveyor belt 18. The base plate 28 is located at the bottom of the support frame 27, and the base plate 28 constitutes a part of the slide 25, and the base plate 28 is located behind the other parts of the slide 25 except the base plate 28. The support frame 27 has a middle partition 58, and the video sensor and the computer control module are respectively installed on the middle partition 58 and located above the base plate 28. The video sensor is used for image acquisition. The middle part of the middle partition 58 is a transparent plate, and the camera of the video sensor is located at the position of the transparent plate to facilitate image acquisition of the electrode plate passing through the base plate 28. The video display screen 40 is installed on the sealed box plate of the control box 41 to display the situation of the electrode plate passing through the base plate 28. The video sensor is electrically connected to the computer control module, the computer control module is electrically connected to the control system, and the output end of the control system is electrically connected to the video display screen 40.

[0075] The bottom plate 28 includes a lamp plate and a glass plate covering the lamp plate. The electrode plate passes through the glass plate. The lamp plate is preferably a white light lamp plate, which is convenient for the clear appearance of the contour line of the image collected by the video sensor.

[0076] The sorting unit 04 also includes a dust removal mechanism, which includes a first dust removal scraper 30, a second dust removal scraper 57 and a driving device. The driving device is a cylinder. The output end of the control system is connected to the control end of the cylinder. The first dust removal scraper 30 moves on the glass plate of the bottom plate 28 to remove lead dust, etc. The second dust removal scraper 57 moves on the transparent plate of the middle partition 58 to remove lead dust, etc. In the present invention, the above-mentioned computer control module is a well-known technology in the industry, and it is not limited in detail as long as it can realize the corresponding functions.

[0077] The first dust scraper 30 is a glass scraper, and its scraping strip is a rubber strip. The first dust scraper 30 is vertically installed above the glass plate of the bottom plate 28, and the active end (i.e., the rubber strip) of the first dust scraper 30 is in contact with the glass plate. The second dust scraper 57 is a glass scraper, and its scraping strip is a rubber strip. The second dust scraper 57 is vertically installed below the transparent plate of the middle partition 58, and the active end (i.e., the rubber strip) of the second dust scraper 57 is in contact with the transparent plate. The cylinder (i.e., the driving device) is installed on the top of the support frame 27, and the cylinder has a piston rod 31, which is transmission-connected to the connecting member 32. The first dust scraper 30 and the second dust scraper 57 are fixed on the connecting member 32 in the lower and upper positions respectively, and the two move synchronously. The connecting member 32 is in the shape of a gantry, with a cross bar at the top, and its piston rod 31 is vertically connected to the middle of the cross bar. In order to make the movement of the first dust scraper 30 and the second dust scraper 57 more stable, two linear slide rails with sliders are provided on the top of the support frame 27, and the two ends of the cross bar are respectively connected to the two sliders of the two linear slide rails. In this way, the connecting member 32 forms three fulcrums (piston rod and two sliders) when moving, which is fast and stable. When removing dust, the movement of the piston rod 31 drives the connecting member 32 to move, and then drives the first dust scraper 30 fixed to the connecting member 32 to move relative to the glass plate, and the second dust scraper 57 to move relative to the transparent plate, so as to synchronously remove lead dust on the glass plate and the transparent plate.

[0078] The slide 25 has a movable block 61 that is pushed upward after receiving a force so that defective products automatically fall from the pushed-open gap to the bottom of the slide 25. Preferably, the movable block 61 is a part cut and separated on the slide 25, and an open groove is formed on the slide 25, and the movable block 61 is installed at the position of the open groove. The movable block 61 is arranged in front of the computer vision device 26, that is, the computer vision device 26 and the movable block 61 are arranged in sequence along the transmission direction. A defective product storage tray 29 is provided below the movable block 61. The defective product storage tray 29 is used to receive defective boards. In this way, the defective boards are separated from the good boards. Preferably, the movable block 61 is driven by a cylinder, and the piston rod of the cylinder is connected to the movable block 61 in a transmission manner. The output end of the control system is connected to the control end of the cylinder.

[0079] A partition mechanism 33 is installed on one side of the slideway 25 along the width direction of the platform. The partition mechanism 33 is located on the output end side of the bottom plate 28 (i.e., located in front of the bottom plate 28). The partition mechanism 33 includes a storage slot 34 for horizontally stacking the partitions and a push plate 35 for pushing out the partitions. The push plate 35 is movably installed at the bottom of the storage slot 34. The bottom of the storage slot 34 is provided with a strip hole for facilitating the output of the partition to the slideway 25. The push plate 35 is arranged corresponding to the strip hole. The partition is preferably a partition plate, and the shape and size of the strip hole match the partition plate. The action end of the push plate 35 can push the partition plate to slide out of the strip hole.

[0080] A limit block is provided at the bottom of the push plate 35. The storage slot 34 is installed on the stand. A limit plate 36 is provided between the stand and the storage slot 34. The limit plate 36 has a limit hole. The limit block slides in the length direction of the limit hole. The push plate 35 is pushed by a cylinder. The cylinder has a piston rod, which is connected to the push plate 35. The output end of the control system is electrically connected to the control end of the cylinder. The control system automatically drives the cylinder to work according to the counting situation of the system to move the push plate 35, and then pushes the push plate 35 to push the separator out of the strip hole onto the slideway 25, so that the separator is located between the two electrode plates.

[0081] During sorting, the video sensor transmits the collected image signal to the computer control module. The computer control module selects the correct image to be analyzed according to the arrangement of pixels, analyzes the contour of the correct image, and determines whether large and small contours exist at the same time. When large and small contours do not exist, a good plate signal is issued and counts normally; otherwise, the positional relationship between the large and small contours is analyzed. When the large contour contains the small contour (the product has defects and is translucent), a product missing signal, i.e., a defective signal, is issued, and the electrode plate does not count. The computer control module feeds back the screening results to the control system. Then the control system automatically controls to open the movable block 61 so that the defective board automatically falls into the defective storage tray 29; when the large contour line is parallel (separated) with the small contour line (lead dust accumulation or part of the previous electrode plate), the circumference of the small contour is calculated, and then a good plate signal (part of the previous electrode plate) is issued, or a good plate signal and a cleaning signal (lead dust accumulation) are issued at the same time, and normal counting is performed at the same time. When the count value reaches the target value set by the customer, the corresponding cylinder is driven to move the push plate 35 and then push the partition from the strip hole to the slide 25. The partition is arranged between two adjacent good boards.

[0082] The output unit includes a second conveyor belt, and the two sides of the second conveyor belt are respectively provided with a stopper 37 and a guide plate 38 that intermittently moves toward the stopper 37 after being subjected to force. The guide plate 38 includes an inclined plate and a straight plate arranged in sequence along the transmission direction. The distance between the inclined plate and the stopper 37 gradually decreases along the transmission direction, and a channel is formed between the straight plate and the stopper 37 for the electrode plates to pass neatly. The second conveyor belt is driven by a common driving and transmission device, such as a motor and a sprocket chain, so as to drive the second conveyor belt to move. The second conveyor belt is arranged to climb forward in an inclined manner. The output end of the second conveyor belt is provided with a good product storage tray 39, and then the good products are collected in a centralized manner. Since the electrode plates arranged in a single row are separated by a separator as an identifier, the stacked good plates can save manual counting. In this way, the screening of the processed electrode plates can be completed. Example

[0083] The difference between this embodiment and the first embodiment lies in the difference in the leveling unit 59 .

[0084] refer to Figure 1-Figure 6 The leveling unit 59 includes a leveling mechanism 02, an anti-overlap mechanism and a buffer. The buffer is preferably a soft buffer belt 17, which is connected to the output end of the input unit 01 and the conveyor belt of the transmission transition unit 03. The buffer belt 17 forms a landslide surface, which can assist the electrode plate to turn to level. At the same time, the buffer belt 17 has a shockproof effect to prevent the electrode plate from being damaged by a large impact when it falls.

[0085] The screening line includes two leveling mechanisms 02, which are arranged side by side along the width direction of the stand. Each leveling mechanism 02 includes a push rod 06, a top plate 07, a mounting seat 08, a first slot-type photoelectric switch 09 and a suction sleeve 10. The suction sleeve 10 is preferably a rubber sleeve, which is elastic and can achieve automatic resetting. The mounting seat 08 is vertically installed between the input unit 01 and the transmission transition unit 03 along the width direction of the stand. The suction sleeve 10 is sealed and connected between the top plate 07 and the mounting seat 08. The top plate 07 is arranged parallel to the mounting seat 08. The suction sleeve 10 is connected to one side of the mounting seat 08 facing the input unit 01, and the other side of the mounting seat 08 facing the transmission transition unit 03 is locked with a slider 13, the slider 13 is equipped with a slide rail 14, the first slot-type photoelectric switch 09 is locked on the slide rail 14, and a sliding fit is formed between the slider 13 and the slide rail 14. The slide rail 14 can slide relative to the slider 13 to adjust the relative position of the first slot-shaped photoelectric switch 09. Meanwhile, the position of the slide rail 14 relative to the slider 13 can be locked by a stop bolt.

[0086] One end of the push rod 06 is fixed to the top plate 07. In this embodiment, the leveling mechanism 02 has two push rods 06 arranged side by side. The mounting seat 08 is provided with two through holes, and the other ends of the two push rods 06 pass through the two through holes respectively, and then the other end of the push rod 06 is movably connected to the mounting seat 08 in a reciprocating manner. The first slot-type photoelectric switch 09 is arranged at a position corresponding to the other end of the push rod 06, and the first slot-type photoelectric switch 09 has a slot channel 12 for the other end of the push rod 06 to pass through to block the light beam. The push rod 06 is made of metal. When the other end of the push rod 06 moves to the slot channel 12 to block the light beam of the first slot-type photoelectric switch 09, the circuit loop of the first slot-type photoelectric switch 09 is disconnected, and the signal is fed back to the control system. In the present invention, the top plate 07 is provided for the electrode plate to stand upright against. The suction sleeve 10 is connected to the vacuum generator. The suction sleeve 10 pulls the top plate 07 through vacuum suction to cause the electrode plate to fall from between the output end of the input unit 01 and the top plate 07 to be laid flat on the transmission transition unit 03 .

[0087] As a preferred embodiment, the state in which the top plate 07 is not subjected to external force is taken as the initial state. In the initial state, the support surface of the top plate 07 and the vertical end surface of the support plate 16 are located in or approximately in the same vertical plane. When the top plate 07 is subjected to the squeezing force of the electrode plate conveyed forward, the top plate 07 moves forward, driving the push rod 06 to move forward. When the other end of the push rod 06 moves to the slot channel 12 to block the light beam, the control system automatically controls the motor to stop working, that is, the conveying chain 15 stops moving, and the top plate and the electrode plate are both in a stationary state. For the convenience of description, the electrode plate close to the top plate 07 is numbered as plate No. 1, and the electrode plate close to plate No. 1 is numbered as plate No. 2. When the conveying chain 15 stops moving, the top plate 07 The distance L between the support surface and the vertical end surface of the support plate 16 is greater than or equal to the thickness δ of the electrode plate (to facilitate the free fall of plate No. 1), and L is less than 2δ (to prevent plate No. 1 and plate No. 2 from free fall at the same time), the bottom of plate No. 1 is separated from the support plate 16, and further, the control system controls the control valve between the suction sleeve 10 and the vacuum generator to open automatically, and the vacuum suction force quickly pulls the top plate 07 forward. At this time, due to the action of gravity, plate No. 1 falls from the gap between the support surface of the top plate 07 and the vertical end surface of the support plate 16, and then flattens on the conveyor belt of the transmission transition unit 03, and plate No. 2 is still supported on the support plate 16, and then the top plate 07 quickly resets to the initial position, repeats the above steps, and guides plate No. 2 to level. It should be noted that the conveying chain 15 is arranged to climb forward in an inclined manner, so that the electrode plate has a backward component force, which prevents plate No. 2 from tipping forward and interfering when plate No. 1 falls, and facilitates the leveling operation of the leveling mechanism 02.

[0088] It should be noted that, 1. In the present invention, according to the thickness of the electrode plate, etc., the position of the slide rail 14 relative to the slider 13 is adjusted to adjust the position of the first slot-type photoelectric switch 09, and then the pause timing of the motor is adjusted to adjust the distance between the support surface of the top plate 07 and the vertical end surface of the support plate 16 in the corresponding state. 2. The leveling operation of the electrode plate is adjusted as needed, for example, two electrode plates can be leveled at the same time, etc. This embodiment only takes the leveling of one electrode plate at a time as an example for explanation. 3. The leveling mechanism 02, the transmission transition unit 03, etc. can be used for leveling or arranging transmission of other sheet structures other than the electrode plate.

[0089] The de-overlapping mechanism includes a vertical rod assembly 19 and a vacuum suction head 20, which are sequentially erected above the first conveyor belt 18 along the transmission direction. The electrode plate is flattened and laid flat on the first conveyor belt 18. In this embodiment, the transmission transition unit 03 is provided with two de-overlapping mechanisms, and the leveling mechanism 02 is arranged one-to-one with the de-overlapping mechanism.

[0090] The vertical rod assembly 19 includes a vertical rod 21, a second slot-type photoelectric switch 22 and a mounting seat 24. The second slot-type photoelectric switch 22 has a slot channel 23 for the top of the vertical rod 21 to penetrate to block the light beam. The mounting seat 24 is mounted above the first conveyor belt 18, and the top of the vertical rod 21 is hinged to the mounting seat 24. The second slot-type photoelectric switch 22 is arranged corresponding to the top of the vertical rod 21, so that when not subject to external force, the top of the vertical rod 21 is located in the slot channel 23. Block the light beam. The distance S1 between the bottom end surface of the vertical rod 21 and the first conveyor belt 18 is greater than the thickness δ of the electrode plate, and S1 is less than 2δ, and the distance S2 between the vacuum suction head 20 and the first conveyor belt 18 is greater than 2δ.

[0091] The state where the vertical rod 21 is not subjected to external force is taken as the initial state. In the initial state, the top of the vertical rod 21 blocks the light beam in the slot channel 23, and the second slot-type photoelectric switch 22 is in a circuit disconnected state. When the relative position of the first slot-type photoelectric switch 09 in the leveling mechanism 02 does not match the thickness of the electrode plate and other factors cause the No. 1 plate and the No. 2 plate to fall at the same time, the No. 1 plate and the No. 2 plate may be completely overlapped or partially overlapped together. At this time, the No. 1 plate and the No. 2 plate form a stacked body. When the bottom of the vertical rod 21 touches the stacked body, as the stacked body moves forward, the vertical rod 21 is pushed forward and tilted, and the top of the vertical rod 21 deviates to the outside of the slot channel 23, so that the second slot The photoelectric switch 22 circuit is connected, and the signal is fed back to the control system. The control system controls the conveyor chain 15 to stop moving. At the same time, the control system transmits the signal to the control end of the vacuum suction head 20. When the stacked body is transported forward to the bottom of the vacuum suction head 20, the vacuum suction head 20 descends and acts on the upper surface of the stacked body by suction, and then moves up after sucking the No. 1 plate, and continues to hold it until the No. 2 plate completely passes through the vacuum suction head 20 (that is, there is no corresponding overlapping part between the No. 1 plate and the No. 2 plate). At this time, the vacuum suction head 20 automatically descends and releases the No. 1 plate, and the No. 1 plate is laid flat on the first conveyor belt 18. Further, the control system starts the motor again, and the conveyor chain 15 continues to move normally. It should be noted that the timing of the vacuum suction head 20 sucking the electrode plate, as well as the gripping time, can be programmed and designed to achieve automation by considering the transfer speed of the first conveyor belt 18.

[0092] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made thereto by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
