The resistor wire and the power cord are respectively inserted and fixed into the mounting holes on the substrate. The existing substrate wiring assembly process is: the substrate is manually loaded onto the conveyor line, one station manually inserts the resistor wire, and another station manually inserts the power cord. After the resistor wire and the power cord are inserted, the substrate is sent to the next process for bending and assembly. A large number of workers are required, and the wiring process is to operate the substrates one by one, which is inefficient. After long-term work, workers are prone to missed insertions, wrong insertions, etc., and the assembly quality is difficult to guarantee.

[0048] like Figure 1 As shown, a power cord and resistor wire plugging machine for a light-emitting device has a resistor wire plugging module 100 and a power cord plugging module 200 installed in parallel along the X-axis direction on a frame. The resistor wire plugging module 100 and the power cord plugging module 200 both include a material picking mechanism 300, a material clamping mechanism 400 and a plugging mechanism 500. The cache mechanism 600 and the substrate conveying line 700 both circulate between the resistor wire plugging module 100 and the power cord plugging module 200.

[0049] like Figure 2As shown, the material taking mechanism 300 is used to take a row of horizontally placed parts (resistance wires or power cords) from the waiting station 800 and convert them into a first posture, which forms an angle with the horizontal plane. Preferably, the first posture is perpendicular to the horizontal plane, so that the next process can accurately take the parts and smoothly insert the parts vertically into the jack of the cache mechanism. The material taking mechanism 300 includes a first Y-axis driving member 310, a rotary cylinder 320 installed on the first Y-axis driving member 310, and a first pneumatic finger 330 installed on the output shaft of the rotary cylinder 320. The first Y-axis driving member 310 can be a common driving device such as an electric lead screw and a rodless cylinder, which can drive the first pneumatic finger 330 to reciprocate along the Y axis and move the parts to a coordinate point convenient for the first pneumatic finger to clamp; the first Y-axis driving member 310 can also flexibly change the initial position and stop position of the first starting finger 330, so that it can clamp resistance wires or power cords of different lengths, thereby enhancing the versatility of the material taking mechanism. In the initial state, the first pneumatic finger 330 is horizontally lying, which is convenient for clamping horizontally placed parts, and then the rotating cylinder 320 flips the first pneumatic finger 330 into the first posture, which is convenient for the clamping mechanism to accurately take away the parts. In this embodiment, the number of the first pneumatic fingers 330 is eight, and the spacing between them is 10 mm, and other numbers and spacings can also be selected.

[0050] like Figures 7 to 9 As shown, the buffer mechanism 600 is used to buffer the resistance wire 901 and the power line 902, and includes a rectangular workbench 610, on which eight carriers 620 for temporarily storing parts are slidably mounted, and a first driving component is fixedly mounted to drive the carriers 620 to move cyclically in a horizontal plane. Fig. 9 , a row of jacks 621 are evenly spaced on each carrier 620. In this embodiment, the number of jacks is eight, and the spacing is 25 mm. Other spacings can also be selected to adapt to substrates with different center distances. At this time, it is only necessary to replace the corresponding carrier on the workbench 610. An elastic component is installed at each jack 621 in the carrier 620 to clamp the resistance wire 901 and the power cord 902 at the same time. The elastic component can be selected from a horizontally installed spring 622 and a pressing block 623 that is squeezed by the spring 622 and pressed against the resistance wire or the power cord. Among them, the cross-sectional shape of the carrier's jack is two interconnected superior arcs, which are convenient for inserting the resistance wire and the power cord respectively. The cooperation of the spring and the pressing block can also clamp the resistance wire or the power cord of different diameters, further improving the versatility of the carrier.

[0051] Specifically, please refer to Figure 7 and Figure 8The first driving assembly includes a first cylinder 631, a second cylinder 632, a third cylinder 633 and a fourth cylinder 634 respectively installed on the four sides of the workbench 610, the first cylinder 631 and the third cylinder 633 both extend along the Y-axis direction, the second cylinder 632 and the fourth cylinder 634 both extend along the X-axis, the first push plate 635 and the third push plate 637 are respectively installed on the sliders of the first cylinder 631 and the third cylinder 633 for moving along the Y-axis direction to fit the workbench, the second push plate 636 and the fourth push plate 638 are respectively installed on the sliders of the second cylinder 632 and the fourth cylinder 634 for moving along the X-axis direction to fit the workbench. The first push plate 635 can push the carrier 620 at the top corner of the workbench to the side of the second cylinder 632, and the second push plate 636 can push the carrier to the side of the third cylinder 633. After four push beats, the carrier 620 arrives at the third push plate 637. The third cylinder 633 pushes the carrier to the side of the fourth cylinder 634 through the third push plate 637. The fourth cylinder 634 pushes the carrier to the side of the first cylinder 631 through the fourth push plate 638. After four push beats, the carrier arrives at the starting point again, realizing the clockwise circular conveying of the carrier. Among them, the carrier 620 receives the resistance wire 901 and the power cord 902 inserted from the material taking mechanism 300 in the above-mentioned second four-continuous push beats, and the carrier 620 provides the cached resistance wire and power cord to the plug-in mechanism 500 in the above-mentioned first four-continuous push beats. Therefore, in the cyclic movement process of the carrier, each process does not interfere with each other.

[0052] Positioning holes 624 are arranged near the edge of the surface of the carrier 620; a swing cylinder 640 is also installed on the workbench 610, and a positioning column 642 matching the positioning hole 624 is installed on the swing block 641 of the swing cylinder 640. The positioning column 642 does not contact the carrier when the carrier 620 moves. When the material taking mechanism 300 inserts the part into the insertion hole 621, or the clamping mechanism 400 takes the part from the insertion hole 621, the swing cylinder 640 inserts the positioning column 642 into the positioning hole 624 to temporarily position the carrier on the workbench 610, so as to prevent the carrier from slightly moving and causing inaccurate action of taking / placing parts, and ensure the stable and continuous operation of the relevant mechanisms.

[0053] Among them, push plate guide rods 639 are installed on the four edges of the workbench 610, and the bottom of each push plate is provided with a guide hole adapted to the push plate guide rod 639. Each push plate moves linearly along the corresponding push plate guide rod 639, ensuring the accuracy of the push plate pushing the carrier.

[0054] Please refer to Figure 3 to Figure 4The clamping mechanism 400 is used to clamp the parts from the material picking mechanism 300 to the carrier 620. The clamping mechanism 400 includes a YZ-axis driving member 410, a variable pitch module 420 installed on the YZ-axis driving member 410, and eight second pneumatic fingers 430 installed on the variable pitch module 420. The variable pitch module 420 is used to change the spacing between two adjacent second pneumatic fingers 420 from the spacing adapted to the parts on the first pneumatic fingers 330 to the spacing adapted to the adjacent sockets on the carrier 620, that is, corresponding to the present embodiment: from 10mm to 25mm. The YZ-axis driving member 410 reciprocates the variable pitch module 420 between the material picking mechanism 300 and the buffer mechanism 600, that is, first lowers the variable pitch module 420 to facilitate the second pneumatic fingers 430 to clamp the parts, and then raises the variable pitch module 420, and moves the variable pitch module 420 above the carrier 620 to facilitate the insertion of the parts into the sockets of the carrier 620.

[0055] Among them, the YZ axis drive member 410 includes a Y axis cylinder 411 and a Z axis cylinder 412 installed on the Y axis cylinder 411. The pitch module 420 includes a support body 421 installed on the Z axis cylinder 412, an X axis drive member 422 installed on the support body 421, and a transmission plate 423 installed on the slider of the X axis drive member 422. The X axis drive member 422 can be a rodless cylinder or an electric lead screw. The transmission plate 423 is connected to the second pneumatic finger at the leftmost end; the eight second pneumatic fingers 430 are arranged into two groups of finger combinations along the X axis direction, each group of finger combinations includes four second pneumatic fingers, and the two groups of finger combinations are staggered on the support body 421. However, the clamps 431 at the bottom of the two groups of finger combinations are bent toward each other so as to be distributed on the same straight line. This structure can not only realize the pitch change of the second pneumatic fingers, but also increase the number of parts to be clamped each time, thereby improving work efficiency.

[0056] Specifically, please refer to Figure 3, the second pneumatic fingers adjacent to each other are connected alternately by the first connecting block 424 and the second connecting block 425, the first connecting block 424 and the second connecting block 425 are respectively provided with the first waist-shaped hole 426 and the second waist-shaped hole 427 along the X-axis direction, and the second pneumatic fingers 430 are respectively provided with the pins 428 which can slide in the first waist-shaped hole 426 and the second waist-shaped hole 427; the second pneumatic finger at the rightmost end is fixedly installed on the support body 421. The output rod of the X-axis driving member 411 contracts to make the second pneumatic fingers in the finger assembly close to each other in a closed state, and the output rod of the X-axis driving member 411 extends to make the second pneumatic fingers in the finger assembly in a dispersed state. Corresponding to this embodiment, in the closed state, the spacing of the finger assembly is 10mm, and in the dispersed state, the spacing of the finger assembly is 25mm, so that the eight second pneumatic fingers 430 can accurately take away eight parts from the first pneumatic fingers at the same time, and then accurately insert the eight parts into the carrier at the same time. In addition, by changing the output stroke of the X-axis driving member 422 to change the variable distance of the second pneumatic finger, the part can be inserted into the carrier sockets with different spacings, thereby improving the versatility of the clamping mechanism 400.

[0057] Two sets of variable pitch guide rails 429 are also installed on the support body 421 along the X-axis direction to accurately guide the variable pitch process of the two sets of finger combinations.

[0058] The wire insertion mechanism 500 is used to insert the parts on the buffer mechanism 600 into the substrate 710 of the substrate conveying line 700. Figure 5 and Figure 6 As shown, the plug-in mechanism 500 includes a three-axis module 510 and a third pneumatic finger 520 installed on the three-axis module 510. The substrate conveyor line 700 is located directly below the three-axis module 510, and reciprocates between the resistor wire plug-in module and the power cord plug-in module to convey the substrates 710 in a rectangular array. The size specifications of the entire board of the substrate can be varied. For example, the diameter of the single board is Φ37.46mm, Φ46.02mm, etc., the size of the entire board is 288*216mm, 315*225mm and other specifications, and the arrangement method can be: 8*6, 7*5 and other methods. The center distance of the arrangement can be 36mm, 45mm and other specifications. The substrate thickness can be 0.8mm, 1.0mm, etc. The substrate conveyor line 700 of this equipment can be applicable to substrates of different specifications mentioned above. Specifically, as Fig.11As shown, the substrate conveyor line includes a conveyor belt body, a fixed side frame, a movable side frame and an adjusting screw. The fixed side frame is fixedly mounted on the frame, and the movable side frame is arranged opposite to the fixed side frame. The left and right sides of the entire substrate are placed on the conveyor belt body on the movable side frame and the fixed side frame respectively. The conveyor belt body is driven to operate intermittently by a motor. Among them, the movable side frame is installed on the slider of the adjusting screw. Rotating the adjusting screw can drive the movable side frame to slide relative to the fixed side frame to change the distance between it and the fixed side frame, so that they can support substrates of different widths. Please refer to Fig.10 The base plate 710 is provided with a mounting hole 711 for fixing the parts. The three-axis module 510 can move the third pneumatic finger 520 to clamp the parts in the carrier socket 621 and then insert it into the mounting hole 711 of the base plate.

[0059] Specifically, a fixing frame 530 is installed on the X-axis module 512 of the three-axis module, and four lifting cylinders 511 are installed on the fixing frame 530 along the X-axis direction. The lifting cylinder 511 is connected to the rotating shaft 532 extending along the Z-axis direction through an adapter block 531. The third pneumatic finger 520 is fixedly installed at the bottom of the rotating shaft 532. The spacing of the third pneumatic fingers 520 is equal to the spacing of the sockets 621 on the carrier, which is convenient for accurately clamping the parts on the carrier. The lifting cylinder 511 can drive the third pneumatic finger 520 to move downward to clamp the parts on the carrier 620; four lifting cylinders 511 are installed on the fixing frame 530, so an independent grasping method can be used when grasping parts, and the grasping and lifting action is more flexible. In addition, the stroke of the lifting cylinder 511 can be appropriately adjusted according to the length of the resistance wire or the power cord, so that the third pneumatic finger 520 can grasp parts of various specifications, and has strong versatility. The X-axis module 512 and the Y-axis module of the three-axis module move the third pneumatic finger 520 to the coordinates of the wire to be inserted, so as to achieve accurate wire insertion.

[0060] like Figure 6 As shown, a row of motors 533 are also installed on the fixed frame 530, and a driving wheel 534 is installed on the output shaft of the motor 533. The driving wheel 534 is connected to the driven wheel 536 through a belt 535. The rotating shaft 532 is keyed to the axis of the driven wheel 536. The motor 533 can drive the third pneumatic finger 520 to rotate an angle through the driving wheel 534, the belt 535 and the driven wheel 536, so as to meet the situation that the mounting holes on different substrates are at different angles, so that the wiring action is more flexible and accurate, the application range is wider, and the versatility is stronger.

[0061] A first sensing sheet 534 is also installed on the output shaft of the motor 533, and a first slot-type proximity switch 513 is installed on the fixing frame 530. When the motor 533 resets the third pneumatic finger 520, the first sensing sheet 534 is driven by the motor and inserted into the first slot-type proximity switch 513 to detect whether the motor accurately resets the third pneumatic finger, thereby ensuring the accuracy of the reciprocating motion of the motor.

[0062] A CCD camera 540 with a downward lens is mounted on the fixing frame 530, and a light source 541 is mounted in front of the CCD camera 540 to provide sufficient light intensity for the CCD camera, and the light source 541 is tilted toward one side of the CCD camera 540. The CCD camera 540 is driven by the three-axis module 510 to the top of the substrate to capture the image of the substrate and upload it to the controller, providing a data basis for the insertion coordinates and rotation angle of the third pneumatic finger 520 on the substrate.

[0063] A second sensing sheet 538 is also installed on the side of the fixed frame 530 close to the substrate, and the projection of the second sensing sheet 538 on the XZ plane is located in the center of the four third pneumatic fingers 520; three second slot-type proximity switches 514 are fixedly installed on the X-axis module 512 of the three-axis module, and the X-axis module 512 can move the second sensing sheet 538 to each second slot-type proximity switch 538. Among them, the middle second slot-type proximity switch is used to detect whether the insertion coordinates of the third pneumatic finger are accurate, and the second slot-type proximity switches on the left and right sides are used to limit the moving stroke of the fixed frame.

[0064] The working process of this wire insertion machine is:

[0065] A row of resistance wires 901 and a row of power lines 902 are horizontally placed on two material waiting stations 800 respectively; the substrate 710 is loaded onto the substrate conveying line 700;

[0066] The first Y-axis driving member 310 of the material picking mechanism 300 drives the rotary cylinder 320 to move to one side of the material waiting station 800, and then the first pneumatic finger 330 clamps a row of parts (resistance wires or power lines), and the rotary cylinder 320 flips the first pneumatic finger 330 to adjust the parts to a vertical state, and the first Y-axis driving member 310 moves the parts to the bottom of the clamping mechanism 400;

[0067] The YZ-axis driving member 410 of the clamping mechanism 400 reciprocates the variable pitch module 420 between the picking mechanism 300 and the buffer mechanism 600, and the variable pitch module 420 changes the spacing of the second pneumatic fingers 430, that is, the YZ-axis driving member 410 first lowers the variable pitch module 420, and the variable pitch module 420 brings the eight second pneumatic fingers 430 together to accurately clamp a row (eight) of parts, and the YZ-axis driving member 410 then raises the variable pitch module 420 and moves the variable pitch module 420 above the carrier 620, and the variable pitch module 420 separates the eight second pneumatic fingers 430, and the second pneumatic fingers 430 insert the eight parts into the jack 621 of the carrier at the same time; the picking and clamping actions of the resistance wire 901 and the power line 902 can be performed synchronously;

[0068] The fourth cylinder 634 of the cache mechanism 600 pushes the carrier 620 fully plugged with power cords (or resistance wires) to the left by two strokes, and the resistance wire plug-in module (or power cord plug-in module) repeats the above action to insert the resistance wire (or power cord) into the carrier, and the fourth cylinder 634 drives the fourth push plate 638 to push the carrier to the left again, and the first cylinder 631 drives the first push plate 635 to push the carrier forward to the front side of the workbench, and the second cylinder 632 pushes the carrier to the right to the bottom of the third pneumatic finger of the resistance wire plug-in module (or power cord plug-in module) to prepare for plugging in the wires;

[0069] The resistance wire plug-in module has a similar plug-in mechanism structure to the power cord plug-in module, so the resistance wire plug-in module is taken as an example to illustrate the working process of its plug-in mechanism: the three-axis module 510 drives the third pneumatic finger 520 to move downward and clamp the resistance wire on the carrier 620; the CCD camera 540 on the front side of the fixing frame 530 captures the position of the substrate 710 and the mounting hole 711, and the controller calculates the substrate coordinates and the rotation angle of the third pneumatic finger 520 based on the captured image, and controls the motor 533 of the plug-in mechanism to drive the third pneumatic finger 520 to rotate to a position corresponding to the angle, and the three-axis module drives the third pneumatic finger 520 to move above the substrate 710. After the second slot-type proximity switch detects that the X-axis of the fixing frame 530 has moved into position, the three-axis module 510 drives the third pneumatic finger 520 to move downward to insert the resistance wire 901 into the mounting hole 711 of the substrate;

[0070] After the wiring on the substrate is completed, the substrate conveying line 700 conveys the substrate 710 to the next wiring insertion mechanism to insert the power line into the substrate.
