Description

Technical Field

[0001] The invention relates to the field of assembly line pin assembly for mobile phone card extraction pins, and in particular to a sleeve pin insertion machine. Background Art

[0002] Currently, mobile phones are all made of thin and light bodies. A special pin is needed to remove the mobile phone card or memory card placed inside the mobile phone. The specific operation is to insert one end of the pin into the pinhole of the card slot on the side of the mobile phone, open the card slot for replacement. The pin is usually fixed on a binding paper and packaged together with the mobile phone manual.

[0003] Traditionally, manual binding is performed on the assembly line. However, since the pins are very small, manual insertion places high demands on the eyes, which can easily cause eye fatigue and is time-consuming and labor-intensive. In addition, since there are many uncontrollable factors in human operation, it is easy to cause problems such as product damage rate or high binding error rate, which is very unfavorable for large-scale binding work.

[0004] In order to overcome the problems of low efficiency and high defective rate caused by manual labor, automated equipment is currently used to replace manual pin insertion and binding operations. For example, the patent document with the announcement number CN208556525U and the publication date of March 1, 2019, entitled "Mobile Phone Card Removal Needle Loading Machine", discloses a mobile phone card removal needle loading machine, including a workbench, a feeding bin, a feeding device, binding paper, a clamping device, a card removal feed plate, and a storage bin. The feeding bin is provided with a pushing device, the feeding device is provided with a feeding tray, the lower end of the feeding tray is provided with a suction cup, the suction cup is provided with an air suction device, the binding paper is provided with a positioning device, and the positioning device is composed of a cylinder and a push plate.

[0005] However, the pin placement trajectory of the existing pin insertion equipment is designed to insert the tip of the pin horizontally or vertically into the fixed hole on the binding paper when the pin is at 180° (0°) or 90° to the binding paper. Horizontal insertion has the problem of difficult hole alignment, while vertical insertion has the problem of random tilting of the pin. Therefore, both pin placement trajectory designs are not easy to place the pins accurately and efficiently, and need further improvement. Summary of the invention

[0006] In order to solve the problem mentioned in the background technology that the existing pin-loading equipment is not easy to place pins accurately and efficiently, the present invention provides an envelope pin-insertion machine, which includes a paperboard material bin, a transfer mechanism, a binding module, a vibration plate, a material separation mechanism, a placement mechanism and a material receiving bin, wherein a plurality of pins are placed in the vibration plate and the pins are transported to the material separation mechanism through vibration;

[0007] The transfer mechanism is used to transport the binding paper to be loaded with needles in the paperboard material bin to the binding module, and to transport the binding paper loaded with needles on the binding module to the receiving bin;

[0008] A lug-lifting mechanism is provided below the binding module, and the lug-lifting mechanism lifts up the clamping lugs on the binding paper, and then the binding module is moved to the operating table of the placing mechanism by the suction cup;

[0009] The placement mechanism clamps the pin output by the material distribution mechanism through a robot, and obliquely inserts the tip of the pin into the fixed hole on the binding paper. When the ear clamp is facing the through hole of the pin, the robot releases the pin to allow the ear clamp to pass through the through hole.

[0010] On the basis of the above structure, further, the transfer mechanism is a double-station synchronous transfer mechanism, and the paperboard bin, the binding module and the receiving bin are sequentially located on the same straight line.

[0011] On the basis of the above structure, further, the placing mechanism includes an operating table and a fixed plate arranged perpendicular to the operating table, a motor and a mechanical arm connected to the manipulator are fixed on both sides of the fixed plate, and the operating table on the side where the mechanical arm is located is used to place the binding paper;

[0012] The output shaft of the motor passes through the fixed plate and is fixed with a driving member. One end of the mechanical arm is slidably connected to the turntable on the fixed plate through a slider, and the other end is connected to the driving member and moves along the placement track on the fixed plate under the drive of the motor so that the tip of the pin is obliquely inserted into the fixed hole on the binding paper.

[0013] On the basis of the above structure, further, the placement track is arranged in a "7" shape so that the insertion pin can be inserted into the fixing hole at an angle of 45 degrees relative to the binding paper.

[0014] On the basis of the above structure, further, the manipulator moves along the length direction of the manipulator arm through a linear drive mechanism.

[0015] On the basis of the above structure, further, one end of the driving member is provided with a U-shaped opening, and a pulley is fixed to one end of the robotic arm connected to the driving member, and the pulley passes through the U-shaped opening and is movably arranged in the placement track.

[0016] On the basis of the above structure, further, a sensor for detecting missed stitches is provided above the binding module.

[0017] On the basis of the above structure, further, an accordion cover is provided on the transmission mechanism of the material receiving bin.

[0018] On the basis of the above structure, further, the material distribution mechanism includes a bracket, and an output port and a needle blocking mechanism arranged on the bracket for outputting the pins. The output port can be disconnected from the pin conveying track under the drive of the linear drive mechanism, and the pins are output one by one through the mutual cooperation of the linear drive mechanism and the needle blocking mechanism.

[0019] On the basis of the above structure, further, the needle blocking mechanism includes a rocker rod and a telescopic rod, the rocker rod is hinged on the bracket and connected to the movable end of the telescopic rod, and the telescopic rod drives the rocker rod to swing back and forth so that the two ends of the rocker rod repeatedly block the input end and output end of the output port in turn.

[0020] The present invention provides an envelope pin insertion machine, which improves the feeding efficiency of pins and binding paper through a vibration plate and a paperboard silo, improves the pin binding efficiency and the qualified rate through the automatic oblique pin loading operation of the ear-pushing mechanism and the placing mechanism of the binding module, and transports the binding paper through the transfer mechanism, which greatly improves the degree of automation, improves the processing efficiency, and reduces the labor cost.

Similar words such as "connected" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, optical connections, etc., whether direct or indirect.

[0044] The present invention provides an envelope pin insertion machine, which includes a paperboard material bin 100, a transfer mechanism 200, a binding module 300, a vibration plate 400, a material separation mechanism 500, a placement mechanism 600 and a material receiving bin 700. A plurality of pins 800 are placed in the vibration plate 400 and the pins 800 are transported to the material separation mechanism 500 by vibration.

[0045] The transfer mechanism 200 is used to transfer the binding paper 900 to be loaded with needles in the paperboard bin 100 to the binding module 300, and to transfer the binding paper 900 loaded with needles on the binding module 300 to the receiving bin 700;

[0046] A lug mechanism is provided below the binding module 300, and the lug sheet 910 on the binding paper 900 is lifted up by the lug mechanism, and then the binding module 300 is moved to the operating table 610 of the placement mechanism 600 by the suction cup;

[0047] The placement mechanism 600 clamps the pin 800 output by the dispensing mechanism 500 through the robot 641, and obliquely inserts the tip of the pin 800 into the fixing hole 920 on the binding paper 900. When the ear clip 910 is opposite to the through hole of the pin 800, the robot 641 releases the pin 800 to allow the ear clip 910 to pass through the through hole.

[0048] When implementing it, Figure 1 and Figure 2 As shown, an envelope pin insertion machine includes a paperboard material bin 100, a transfer mechanism 200, a binding module 300, a vibration plate 400, a material dividing mechanism 500, a placement mechanism 600 and a material receiving bin 700; a plurality of pins 800 are placed in the vibration plate 400, and the vibration plate 400 is connected to the material dividing mechanism 500 through a pin conveying track. The vibration plate 400 arranges the pins 800 in an orderly manner on the pin conveying track and conveys them to the material dividing mechanism 500 by vibration, and then the pins 800 are output by the material dividing mechanism 500 so as to be clamped by the manipulator 641 of the placement mechanism 600;

[0049] The binding paper 900 to be stapled is stacked vertically in the cardboard bin 100. The binding paper 900 is lifted to a position where the transfer mechanism 200 can grab it through a lifting mechanism for vertically conveying the cardboard. The staff can load the binding paper 900 on the ground, which is simple and convenient.

[0050] The transfer mechanism 200 can move back and forth above the paperboard bin 100 , the binding module 300 and the receiving bin 700 , and specifically transport the binding paper 900 to be stapled in the paperboard bin 100 to the binding module 300 by means of a suction cup.

[0051] A lug mechanism is provided below the binding module 300, which can be a mechanical ejection device, a hydraulic ejection device or a pneumatic ejection device. When the binding paper 900 is placed on the binding module 300, the two clamping lugs 910 on the binding paper 900 are aligned with the two top mold holes on the binding module 300, and the two clamping lugs 910 on the binding paper 900 are lifted up through the top mold holes by the movable end of the lug mechanism, and then the binding module 300 together with the binding paper 900 is moved to the operating table 610 of the placement mechanism 600 by the suction cup, waiting for the placement of the pin 800;

[0052] The placement mechanism 600 clamps the pin 800 output by the material distribution mechanism 500 through the manipulator 641, and obliquely inserts the tip of the pin 800 into the fixed hole 920 on the binding paper 900. When the erected clamping ear piece 910 is facing the through hole of the pin 800, the manipulator 641 releases the pin 800, and the pin 800 naturally falls onto the binding paper 900, and the two clamping ear pieces 910 pass through the through hole; at this time, the movable end of the top ear mechanism is retracted, and the two clamping ear pieces 910 fall back under the action of their own rebound force to clamp the pin 800 and fix it; the needle loading operation is completed. The binding paper 900 with needles is returned to the initial station of the binding module 300, and the transfer mechanism 200 moves the binding paper 900 with needles on the binding module 300 to the receiving bin 700 through the suction cup, waiting for manual material collection and packaging.

[0053] The specific process of binding is as follows: the staff loads the binding paper 900 into the paperboard bin 100, and moves the binding paper 900 in the paperboard bin 100 to the top of the binding module 300 by means of a suction cup through the transfer mechanism 200, and lifts up the two clipping ear pieces 910 on the binding paper 900 through the ear-lifting mechanism under the binding module 300, and then moves it to the operating table 610 of the placement mechanism 600 by means of a suction cup;

[0054] At the same time, the vibration plate 400 equipped with a plurality of pins 800 transmits the pins 800 in an orderly manner to the dividing mechanism 500 by means of vibration, and the pins 800 are clamped by the manipulator 641 of the placing mechanism 600. After the pins are taken out, the tips of the pins 800 are obliquely inserted into the fixing holes 920 on the binding paper 900 and placed in place; after the pins are placed, the movable end of the ear mechanism is retracted, and the two ear clamping pieces 910 fall back under the action of their own rebound force to clamp and fix the pins 800, and the binding paper 900 with the pins is returned to the initial station of the binding module 300, and the transfer mechanism 200 transports the binding paper 900 with the pins on the binding module 300 to the receiving bin 700, waiting for manual material retrieval and packaging.

[0055] The present invention provides an envelope pin insertion machine, which improves the feeding efficiency of pins and binding paper through a vibration plate and a paperboard silo, improves the pin binding efficiency and the qualified rate through the automatic oblique pin loading operation of the ear-pushing mechanism and the placing mechanism of the binding module, and transports the binding paper through the transfer mechanism, which greatly improves the degree of automation, improves the processing efficiency, and reduces the labor cost.

[0056] Preferably, the transfer mechanism 200 is a double-station synchronous transfer mechanism, and the paperboard bin 100, the binding module 300 and the receiving bin 700 are sequentially located on the same straight line.

[0057] When implementing it, Figure 1 As shown, the transfer mechanism 200 is a double-station synchronous transfer mechanism, the paperboard bin 100, the binding module 300 and the receiving bin 700 are successively located on the same straight line, and the double-station synchronous transfer mechanism can be located on the paperboard bin 100 and the binding module 300 at the same time, and on the binding module 300 and the receiving bin 700 at the same time, that is, the feeding operations of moving the binding paper 900 to be stapled to the binding module 300, and moving the stapled binding paper 900 to the receiving bin 700 are performed synchronously, which is beneficial to improving the stitching efficiency.

[0058] Preferably, the placing mechanism 600 includes an operating table 610 and a fixing plate 620 arranged perpendicular to the operating table 610, a motor 630 and a mechanical arm 640 connected to the mechanical arm 641 are fixed on both sides of the fixing plate 620, and the operating table 610 on the side where the mechanical arm 640 is located is used to place the binding paper 900;

[0059] The output shaft of the motor 630 passes through the fixed plate 620 and is fixed with a driving member 631. One end of the mechanical arm 640 is slidably connected to the turntable 643 on the fixed plate 620 through a slider 642, and the other end is connected to the driving member 631 and moves along the placement track 621 on the fixed plate 620 under the drive of the motor 630, so that the tip of the pin 800 is obliquely inserted into the fixed hole 920 on the binding paper 900.

[0060] When implementing it, Figure 3-6 As shown, the placement mechanism 600 includes a horizontally placed operating table 610 and a fixed plate 620 arranged perpendicular to the operating table 610, and a motor 630 and a mechanical arm 640 connected to a mechanical hand 641 are fixed on both sides of the fixed plate 620, and the operating table 610 on the side where the mechanical arm 640 is located is used to place the binding paper 900;

[0061] The output shaft of the motor 630 passes through the fixed plate 620 and is fixed with a driving member 631. One end of the robot arm 640 is slidably connected to the turntable 643 on the fixed plate 620 through the slider 642, that is, the robot arm 640 can rotate along the surface of the fixed plate 620 through the turntable 643 and can slide relative to the turntable 643. The other end of the robot arm 640 is connected to the driving member 631 and moves along the placement track 621 on the fixed plate 620 under the drive of the motor 630. At the same time, the robot arm 640 makes adaptive adjustments through the turntable 643 and the slider 642, thereby changing the placement position of the entire robot arm 640 so that the tip of the pin 800 is obliquely inserted into the fixed hole 920 on the binding paper 900.

[0062] It should be noted that the placement of the rail 621 will change the placement position of the robot arm 640, thereby changing the angle between the pin 800 and the binding paper 900 when it is inserted. As for the specific placement rail 621 to be used, those skilled in the art can make a corresponding design based on the concept provided by the present invention and the above description.

[0063] Preferably, the placement rail 621 is arranged in a hollow or grooved manner on the fixing plate 620 .

[0064] In a specific implementation, the rail 621 is placed on the fixed plate 620 in a hollow or grooved manner to facilitate processing and forming. Figure 4 and Figure 6 As shown, the placement rail 621 is arranged in a hollow manner on the fixing plate 620 .

[0065] Preferably, the placement track 621 is arranged in a "7" shape so that the insertion pin 800 can be inserted into the fixing hole 920 at an angle of 45° relative to the binding paper 900.

[0066] When implementing it, Figure 4 and Figure 6 As shown, the placement track 621 is arranged in a "7" shape. When one end of the robot arm 640 connected to the driving member 631 is located at the straight section of the lower part of the placement track 621, the angle between the robot arm 640 and the operating table 610 is 45°, so that the pin 800 is inserted into the fixing hole 920 on the binding paper 900 at an angle of 45°.

[0067] Preferably, the manipulator 641 is a pneumatic finger.

[0068] In specific implementation, the robot arm 641 is a pneumatic finger that accurately simulates human grasping movements, effectively improving production efficiency and work safety.

[0069] Preferably, the manipulator 641 moves along the length direction of the manipulator 640 via a linear drive mechanism.

[0070] In specific implementation, the manipulator 641 moves along the length direction of the robot arm 640 through a linear drive mechanism to expand the range of motion of the manipulator 641 and improve flexibility. The linear drive mechanism is preferably a linear cylinder or an electric push rod, which has high accuracy, can achieve precise control, and runs smoothly with low energy consumption.

[0071] Preferably, a U-shaped opening is provided at one end of the driving member 631 , and a pulley is fixed to one end of the mechanical arm 640 connected to the driving member 631 , and the pulley passes through the U-shaped opening and is movably disposed in the placement track 621 .

[0072] When implementing it, Figure 4 and Figure 6 As shown, a U-shaped opening is provided at one end of the driving member 631, and a pulley is fixed at one end of the mechanical arm 640 connected to the driving member 631, so that the connection part between the pulley and the mechanical arm 640 is placed from the opening at the end, so that the pulley passes through the U-shaped opening on the driving member 631;

[0073] The pulley passes through the U-shaped opening and is movably arranged in the placement track 621. Since the U-shaped opening has a certain length, when the motor 630 is running, the rotation of the driving member 631 will drive the pulley to move along the placement track 621, thereby driving one end of the mechanical arm 640 to move, and the position of the other end of the mechanical arm 640 is adaptively adjusted through the turntable 643 and the slider 642, thereby changing the placement position of the entire mechanical arm 640. The advantage of using a pulley is that it can reduce the friction between the placement track 621 during movement, making it easier to move the mechanical arm 640.

[0074] Preferably, a sensor for detecting missed stitches is also provided above the binding module 300 .

[0075] In specific implementation, after the placement mechanism 600 completes the needle loading, a sensor above the binding module 300 is used to detect whether a needle is missing. The sensor can be a capacitive or inductive sensor, and the specific model is ZJG81-8-M8-L30-NK.

[0076] Preferably, the binding module 300 is also provided with a positioning device for fixing the binding paper 900 .

[0077] In specific implementation, the positioning device is composed of a pressing plate and a cylinder. The pressing plate is fixed on the movable end of the cylinder. When the binding paper 900 is placed on the binding module 300, the cylinder drives the pressing plate to press the edge of the binding paper 900 to fix it.

[0078] Preferably, an accordion cover 710 is provided on the transmission mechanism of the material receiving bin 700 .

[0079] When implementing it, Figure 1 and Figure 2As shown, an accordion cover 710 is provided on the transmission mechanism of the receiving bin 700 to prevent dust and ash.

[0080] Preferably, the material distribution mechanism 500 includes a bracket 510, and an output port and a needle blocking mechanism arranged on the bracket 510 for outputting the pins 800. The output port can be disconnected from the pin conveying track under the drive of the linear drive mechanism, and the pins 800 can be output one by one through the mutual cooperation of the linear drive mechanism and the needle blocking mechanism.

[0081] In specific implementation, the material distribution mechanism 500 includes a bracket 510, an output port and a needle blocking mechanism for outputting the pin 800, the output port is fixed to the bracket 510 by a linear drive mechanism, and the output port can be disconnected or connected to the pin conveying track under the drive of the linear drive mechanism; the linear drive mechanism can be a linear cylinder or an electric push rod, which has high accuracy, can achieve precise control, and runs smoothly with low energy consumption.

[0082] The pin blocking mechanism blocks the output port away from the pin delivery track, i.e., the output end 522, to prevent the pin 800 from being output; and blocks the output port close to the pin delivery track, i.e., the input end 521, to push the pin 800 in the output port out of the output end 522 so that the manipulator 641 of the placement mechanism 600 can pick it up, and at the same time, the pin 800 on the pin delivery track behind is blocked to prevent it from entering the output port. By setting the pin blocking mechanism and the linear drive mechanism connected to the output port to cooperate with each other, the output frequency of the pin 800 can be controlled to achieve one-by-one output.

[0083] Preferably, the needle blocking mechanism includes a rocker rod 530 and a telescopic rod 540, the rocker rod 530 is hinged on the bracket 510 and connected to the movable end of the telescopic rod 540, and the telescopic rod 540 drives the rocker rod 530 to swing back and forth, so that the two ends of the rocker rod 530 repeatedly block the input end 521 and the output end 522 of the output port in turn.

[0084] When implementing it, Figure 7-10 As shown, the needle blocking mechanism includes a rocker arm 530 and a telescopic rod 540. The rocker arm 530 is hinged on the bracket 510 and connected to the movable end of the telescopic rod 540. The telescopic rod 540 drives the rocker arm 530 to swing back and forth, so that the two ends of the rocker arm 530 repeatedly block the input end 521 and the output end 522 of the output port between the output port and the pin conveying track.

[0085] like Figure 7 and Figure 8 As shown, when the telescopic rod 540 is in the retracted state, one end of the swing rod 530 is located at the output end 522 of the output port to block the pin 800 from being output from the output port;

[0086] like Fig. 9 and Fig.10 As shown, when the telescopic rod 540 is in the extended state, the other end of the rocker arm 530 is located between the input end 521 of the output port and the pin conveying track, the pin 800 in the output port is pushed out of the output end 522 so as to be clamped by the manipulator 641 of the placement mechanism 600; at the same time, the pin 800 on the pin conveying track behind is blocked to prevent it from entering the output port.
