[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0036] like Figure 1 and Figure 4The embodiment of the present invention preferably provides a feeding device for a counting and stacking machine, comprising: a frame 1, and a feed section 1 2 and a feed section 2 3, which are spliced ​​together on the frame 1; the feed section 1 2 including a plurality of transversely spaced conveyor belts 1 4; and the feed section 2 3 including a plurality of transversely spaced conveyor belts 2 6, which are interlaced with the conveyor belt 1 4 and have a baffle 2 7 disposed longitudinally and movable at the end thereof away from the conveyor belt 1 4 to block the stacked sheets on the conveyor belt 2 6. Specifically, the interlaced and spliced ​​conveyor belts 1 4 and 2 6 enable segmented, seamless conveying of the sheets. Furthermore, by driving and fixing the baffle 2 7 to a predetermined suction cup 61 material removal position of the counting and stacking machine, the stacked sheets passing through the conveyor belts 1 4 and 2 6 are moved to abut against the baffle 2 7 during single-stack feeding, thereby ensuring the flatness of the stacked sheets.

[0037] like Figures 2 to 3 As shown, a baffle 5 is provided at the end of the feeding area 2 to be movable horizontally for blocking the stacked sheet materials on the conveyor belt 4. Specifically, the conveyor belt 14 and the conveyor belt 2 6 are staggered and spliced ​​to achieve segmented seamless transportation of the conveyed sheet materials. The baffle 5 is driven and fixed to move to the conveyor belt 4 to block the stacked sheet materials on the conveyor belt 4, so that when double stack feeding is required, the baffle 5 is driven to move horizontally to the conveyor belt 4 to support the first stacked sheet materials. After the first stacked sheet materials are supported and leveled, the conveyor belt 4 stops working, and the baffle 5 is driven to move horizontally and reset. The conveyor belt 4 and the conveyor belt 2 6 work synchronously to allow the leveled first stacked sheet materials to enter the feeding area 2 3. The baffle 5 continues to move horizontally to the conveyor belt 4 to work. The second stacked sheet materials are moved by the conveyor belt 4 to support the baffle 5 to achieve the second stack. The stacked sheets of the first stack are supported and leveled. After the second stacked sheets are leveled, the conveyor belt 1 4 stops working, the baffle 1 5 is driven to move horizontally and reset, and the conveyor belt 1 4 and the conveyor belt 2 6 work synchronously. The stacked sheets of the first stack and the stacked sheets of the second stack enter the feeding area 2 3 synchronously to ensure the levelness of the stacked sheets during double-stack feeding. During double-stack feeding, the staggered conveying cooperation of the conveyor belt 1 4 and the conveyor belt 2 6 is used to ensure that the spacing between the stacked sheets of the first stack and the stacked sheets of the second stack of each different batch size is equal, and the spacing between the stacked sheets of the first stack and the stacked sheets of the second stack is adjustable.

[0038] A baffle 3 8 that can move up and down is provided at the lower end of the baffle 15. A cylinder 9 is provided on the baffle 15 to drive the baffle 3 8 to move up and down. A number of protrusions 10 are provided at the lower end of the baffle 3 8 at horizontal intervals. The protrusions 10 can move up and down with the baffle 3 8 and are set in the gap formed by two adjacent conveyor belts 4. Specifically, the protrusions 10 support the sheet material at the lower end of the stacked sheets to ensure the uniform flatness of the stacked sheets.

[0039] The lower end of the baffle 2 7 is laterally spaced with a plurality of protrusions 2 11 , which are arranged in the gap formed by the two adjacent conveyor belts 2 6 . Specifically, the protrusions 2 11 support the sheet material at the lower end of the stacked sheets to ensure the uniformity of the flatness of the stacked sheets.

[0040] The frame 1 is provided with a second cylinder 12 for driving the baffle 1 5 to move laterally, and the conveyor belt 2 6 is provided with a plurality of light sensing elements at intervals in the longitudinal direction, and the position of the stacked sheets is detected by the position of the light sensing elements.

[0041] The frame 1 is provided with a reference plate 13 on one side of the conveyor belt 4 for the sheet material to lean against.

[0042] like Figures 1 to 3 What is presented is a counting and stacking machine, comprising: a feeding device for a counting and stacking machine as described above, as well as a picking device 14, a lifting device, a qualified placement area 17, an unqualified placement area 18 and a transverse movement device 18, wherein the qualified placement area 17 is arranged on one side of the feeding area 2 3, and the unqualified placement area 18 is arranged on the other side of the feeding area 2 3; wherein the picking device 14 comprises one or more suction cups 61, and a driving member connected to the suction cup 61 for driving the suction cup 61 to move up and down; a lifting device, which is connected to the picking device 14 for driving the picking device 14 to move up and down; a transverse movement device 18, which is connected to the lifting device for driving the picking device 14 to move laterally with the lifting device for displacement and sorting above the qualified placement area 17, the unqualified placement area 18 and the feeding area 2 3 respectively. Specifically, the driving part is a cylinder or an electric telescopic rod, the lifting device includes a screw, a motor and a screw sleeve that is fitted on the screw with a thread, the motor drive shaft is connected to the screw to cause the screw to rotate, and the screw sleeve moves up and down along the screw; the transverse movement device 18 includes a stepper motor, a slider and a linear track, the slider is movably arranged in the linear track, the stepper motor drive shaft is connected to the slider, and the lifting device is arranged on the slider; the lifting device, the transverse movement device 18 and the material picking device 14 are combined to realize single-row counting stacking or double-row counting stacking of stacked sheets.

[0043] When stacking, you can either count and stack directly, and then directly send out for inspection, labeling, or continuous packaging after reaching the set number. You can also set up staggered stacking by counting, such as setting 25 pieces x 4 stacks, with each stack staggered. When the count reaches 25 pieces, the transverse movement device 18 automatically drives the material removal device 14 to move horizontally to the set position, while the longitudinal movement device remains in the same position, continuing to feed the material to the stacking area and stacking to the set number, thus achieving the effect of staggered stacking. The transverse movement device 18 then drives the material removal device 14 to return to its original position, and staggered stacking continues, and so on, until the set number of stacks is reached. After the sheet materials are fed, they are counted or staggered and stacked. When the single stack count is completed, the subsequent conveyor belt can be continuously fed. If the set production stack count has been completed and there is still residual material to be changed, the residual material can be retreated by conveyor belt 1 4 and conveyor belt 2 6 and then manually replaced. If the double stack is counted and stacked, and the last two stacks have different numbers of residual materials, the residual material will be sucked into the unqualified placement area 18 to facilitate subsequent feeding. Continuous counting and stacking saves time. If the set stack count has been reached and the remaining stock needs to be changed, the residual material button will be manually retreated, manually eliminated, and then the next batch number feeding will continue.

[0044] like Figures 7 to 9 As shown, the suction cup 61 has a flow channel 62 for air circulation from one end to the other, and a valve 63 is hingedly connected within the flow channel 62 for blocking the flow channel 62. The valve 63 is arranged at an angle to the horizontal plane or in a ring shape. Specifically, when the suction cup 61 is in its initial state, the valve 63 is open due to its own weight. When the suction cup 61 is in a working state without adsorbing a workpiece, the flow of vacuum air through the flow channel 62 causes the valve 63 to close. The closed valve 63 seals the flow channel 62 to prevent the suction cup 61 from accidentally adsorbing other objects. When the suction cup 61 is in a working state to adsorb a workpiece, the flow of vacuum air through the flow channel 62 causes the valve 63 to close. When the workpiece is adsorbed, the flow rate of air in the flow channel is reduced, and the valve 63 is opened due to its own weight, generating a vacuum, thereby firmly adsorbing the workpiece to prevent overlapping adsorption. Alternatively, the valve 63 is opened by the elastic force of a spring or coil spring.

[0045] And because the circuit board has many holes or gaps, the position of the leak is Figure 10 As shown, the dense arrangement is rectangular or circular. Because the suction cup 61 has a self-sealing action, when the suction cup 61 contacts a hole, a gap or a leaking position, the valve 63 of the suction cup 61 is closed to reduce air leakage. When it is sucked to a sealed position, the suction cup 61 strongly absorbs the workpiece, so that circuit boards with holes of various shapes can be sucked without moving the suction cup 61. This ensures that the circuit board can be firmly sucked without moving the suction cup 61, greatly improving work efficiency. Figure 11 As shown, the suction cup 61 is externally connected to a vacuum generator or a vacuum pump and controlled by a solenoid valve to achieve the effect that the suction cup 61 has a large flow rate, a small size, and is light.

[0046] The system further comprises a detection device, which is arranged on the material taking device 14 and includes at least a camera. When the material taking device 14 takes the material and stacks it, the camera of the detection device performs electronic detection to detect the number of circuit boards stacked.

[0047] It also includes a separator paper placement area located below the material taking device 14, in which a separator paper pile is placed in a predetermined area, and the separator paper pile includes multiple stacked separator papers. Specifically, in the absence of an inspection mode, the separator paper function is selected to count the stacking, and the same counting stacking action can be performed. First, the separator paper (or sheet material) is sucked and placed in the qualified placement area 17, and then the subsequent suction cup 61 sucks the sheet material and places it on the separator paper, and then continues to suck and place the separator paper and sheet material. If the first (bottom) and last (top) cardboard are required to be placed, the cardboard is placed on the left side of the unqualified placement area 18 and the separator paper is placed on the right side. It can be programmed to drive the first and last cardboards of each stack to be sucked and placed, and the separator paper and sheet material in the middle are sucked and placed for counting and stacking.
