[0037] A paper pin insertion machine, see Figures 1 to 10 ,include:

[0038] Workbench 1;

[0039] And installed on workbench 1:

[0040] The transmission mechanism 2 is provided with a pre-folding ear point and a pin insertion point;

[0041] A paper traction rack 11, located above the conveying mechanism 2, and used for carrying paper sheets;

[0042] The paper suction mechanism 12 is located directly below the paper traction rack 11 and is used for sucking paper sheets onto the conveying mechanism 2;

[0043] The pre-folding mechanism 3 includes a lower folding portion 4 that abuts against the folded ear of the paper sheet at the pre-folding point and a folding track 5 that is arranged along the conveying direction of the conveying mechanism 2 for the folded ear to pass through;

[0044] The pin insertion mechanism 6 comprises a feeding part 7 for conveying the pin to the pin insertion point, an ear clamping part 8 with a folded ear in a vertical paper state for clamping the pin insertion point, and a manipulator 9 for clamping the pin and passing it through the folded ear in a vertical state.

[0045] When the pin insertion machine is working, first, the paper suction mechanism 12 absorbs a piece of paper from the paper traction rack 11 to the conveying mechanism 2, and the conveying mechanism 2 moves the paper to the pre-folding point, and the folded ears of the paper are abutted upward through the lower folding ear part 4, so that the two folded ears abut against the two side walls of the folding ear track 5, and move to the pin insertion point along the folding ear track 5 under the transportation of the conveying mechanism 2, and the ear clamping part 8 clamps the two folded ears in the folding ear track 5 vertically, so that the robot 9 can insert the insertion pin delivered by the feeding part 7 into the two vertical folded ears, thereby completing the pin insertion action; the whole process does not require manual operation, which improves production efficiency.

[0046] In this embodiment, the paper suction mechanism 12 is a cylinder and a suction cup structure installed on the cylinder output shaft.

[0047] Preferably, the lower folding ear part 4 includes a lower folding ear cylinder 41 which is relatively arranged and installed below the conveying mechanism 2, and a flattening cylinder 42 which is installed above the conveying mechanism 2, the output shaft of the lower folding ear cylinder 41 is installed with a fixed block 411, one end of the fixed block 411 is provided with a "V"-shaped folding ear block 412, and the output shaft of the flattening cylinder 42 is provided with a flattening block 421.

[0048] During pre-folding of the ears, the lower ear folding cylinder 41 drives the ear folding block 412 to move upward, so that the two ears on the paper sheet at the pre-folding point are bent upward. At the same time, the flattening cylinder 42 drives the flattening block 421 to abut against the fixed block 411, so that the paper sheet is clamped to prevent one side of the paper sheet from being bent and offset due to uneven force, which affects the pre-folding effect.

[0049] Preferably, a semicircular pressing cylinder 43 is installed on one side of the flattening cylinder 42, and the semicircular pressing cylinder 43 is located at the lower side of the folding ear. The semicircular pressing cylinder 43 can realize the molding of the semicircular notch on the lower side of the folding ear on the paper sheet so that the needle tip can be inserted and fixed.

[0050] Preferably, a buffer block 13 is further included, which is installed on one side of the conveying mechanism 2 and abuts against the paper sheet. The buffer block 13 abuts against the paper sheet to maintain the surface tension of the paper sheet and prevent the paper sheet from deviating during processing.

[0051] Preferably, the feeding part 7 includes a vibration plate 71, a feeding track 72 and a needle delivery assembly 73 arranged at the end of the feeding track 72; the needle delivery assembly 73 includes a needle delivery platform 731, a needle delivery plate 732 slidably connected to the needle delivery platform 731 in a direction perpendicular to the feeding track 72, a power cylinder 733 driving the needle delivery plate 732 to slide, a needle delivery track 734 arranged on the needle delivery plate 732 and capable of communicating with the feeding track 72, and a needle delivery cylinder 735 arranged on the needle delivery platform 731 for pushing the needle inserted in the needle delivery track 734, the needle delivery platform 731 is provided with a needle pressing block 736 for abutting the needle inserted in the needle delivery track 734, and a needle pushing block 737 is installed on the output shaft of the needle delivery cylinder 735.

[0052] During feeding, the vibration plate 71 conveys the pins one by one along the feeding track 72, and the power cylinder 733 drives the needle delivery plate 732 to slide back and forth, so that the needle delivery track 734 and the feeding track 72 can transfer the pins when they are aligned. When they are misaligned, the needle delivery cylinder 735 drives the needle push block 737 to move, so that the needle push block 737 pushes the pins in the needle delivery track 734 out of the needle delivery track 734 to facilitate the robot 9 to clamp them. The design of the needle pressing block 736 can prevent the pins from curling up, ensuring that the pins are delivered one by one.

[0053] Preferably, the ear clamping part 8 includes an ear clamping cylinder 81 installed below the conveying mechanism 2, a lifting cylinder 82 that drives the ear clamping cylinder 81 to approach and move away from the pin insertion point, and a leveling cylinder 83 provided on one side of the ear clamping cylinder 81 and used to abut against the paper sheet, and the output shaft of the leveling cylinder 83 is installed with a leveling block 84 for abutting against the paper sheet.

[0054] In this embodiment, the flattening block 84 has a similar function to the flattening block 421, and is used to abut against the paper sheet to prevent the paper sheet from bending and deviating due to uneven force. When the paper sheet moves to the pin insertion point, the lifting cylinder 82 first drives the clamping ear cylinder 81 to abut against the folding ear, and the clamping ear cylinder 81 moves to bring the two folding ears closer together to facilitate the insertion of the pin hole. At the same time, the flattening cylinder 83 drives the flattening block 84 to abut against the lower surface of the paper sheet.

[0055] Preferably, the manipulator 9 includes a mounting plate 91, a needle loading frame 92 slidably connected to the mounting plate 91 along the direction of the feeding track 72, a first driving cylinder 93 for driving the needle loading frame 92 to slide, a needle loading plate 94 hinged on the needle loading frame 92, a second driving cylinder 95 for driving the needle loading plate 94 to rotate, and a pinching cylinder 96 installed on the needle loading plate 94 and pinching the needles inserted on the needle delivery track 734. One end of the second driving cylinder 95 is hinged to the mounting plate 91, and the other end is hinged to the free end of the needle loading plate 94.

[0056] When the manipulator 9 is working, first, the kneading cylinder 96 clamps the pin on the needle delivery track 734, and then the first driving cylinder 93 drives the needle loading frame 92 to slide down, so that the pin clamped by the kneading cylinder 96 is close to the folding ear at the pin insertion point (at this time, the folding ear has been tightened and erected under the action of the ear clamping cylinder 81), and then the second driving cylinder 95 contracts, so that the kneading cylinder 96 and the needle loading plate 94 rotate around the needle loading frame 92, thereby realizing the pin clamped on the kneading cylinder 96 is set on the folding ear.

[0057] Preferably, the workbench 1 is provided with an adjustment mechanism 10 for adjusting the distance between the manipulator 9 and the pin insertion point. The setting of the adjustment mechanism 10 facilitates workers to process origami with different pin insertion positions.

[0058] Preferably, the adjustment mechanism 10 includes an adjustment plate slidably connected to the workbench 1 along a conveying direction perpendicular to the conveying mechanism 2 and a screw structure for driving and positioning the adjustment plate, and the mounting plate 91 is mounted on the adjustment plate.

[0059] Preferably, a flattening detection mechanism 14 is further included at the end of the conveying mechanism 2, and the flattening detection mechanism 14 includes a detection cylinder installed on the workbench 1 and a metal detector and a pressure block installed on the output shaft of the detection cylinder. The metal detector is used to detect whether the pin is installed on the folding ear, and the pressure block is used to flatten the folded folding ear to facilitate later packaging.

[0060] The above embodiments are merely explanations of the present application and are not limitations of the present application. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present application, they are protected by the patent law.
