Description

Technical Field

[0001] The invention relates to the field of pen manufacturing equipment technology, and in particular to an assembly device for a direct-liquid pen refill assembly. Background Technology

[0002] As attached Figure 1 As shown in -a, 1-b, and 1-c, the direct-liquid rollerball pen A has an internal ink chamber for storing ink. The pen A includes a pen shell a, an ink regulator b, and a direct-liquid refill assembly c. Ink flow is regulated by the ink regulator b and the direct-liquid refill assembly c. The ink regulator b has leak-proof and air-return functions. The ink in the ink chamber is guided to the pen tip c4 via the ink guide c1 and the ink guide fiber c3 to provide ink flow for writing. The direct-liquid refill assembly is a key structure in the direct-liquid pen, as shown in the attached diagram. Figure 1 As shown in Figure -c, a direct-liquid pen refill assembly typically includes a pen tip (c4), a water-guiding fiber (c3), a connecting sleeve (c2), and a water-guiding core (c1). During assembly, one end of the water-guiding fiber (c3) is first inserted into the pen tip (c4). Then, the end of the pen tip (c4) corresponding to the water-guiding fiber (c3) is inserted into the front end of the connecting sleeve (c2). Next, the water-guiding core (c1) is inserted into the rear end of the connecting sleeve (c2), with the water-guiding fiber (c3) inserted into the water-guiding core (c1). Finally, a stamping device deforms the overlapping portion of the connecting sleeve (c2) and the water-guiding core (c1) to prevent separation, completing the assembly of the direct-liquid pen refill assembly. These steps are often performed manually, resulting in low assembly efficiency and a low product qualification rate, which is unfavorable for mass production. Summary of the Invention

[0003] The purpose of this invention is to provide an assembly device for direct-liquid pen refill components. This invention enables automated assembly of direct-liquid pen refill components, which not only has high assembly efficiency but also significantly improves product qualification rate, facilitates mass production, and brings good economic benefits to enterprises.

[0004] To achieve the above objectives, the invention provides the following technical solution: an assembly device for a direct-liquid pen refill assembly, comprising a frame and a conveying device disposed on the frame for conveying semi-finished products. The frame is provided sequentially along the conveying direction of the conveying device, including a pen tip feeding device for placing the pen tip on the conveying device, a water-guiding fiber assembly device for inserting the water-guiding fiber into the rear end of the pen tip, a connecting sleeve assembly device for assembling the connecting sleeve onto the pen tip, a water-guiding core assembly device for inserting the water-guiding core into the connecting sleeve, a deformation device for pressing and fitting the overlapping part of the connecting sleeve and the water-guiding core, and a discharge device for discharging the finished pen refill assembly.

[0005] By adopting the above technical solution, the various devices work together to automatically insert one end of the water-guiding fiber into the rear end of the pen tip, then put the front end of the connecting sleeve onto the rear end of the pen tip, then insert the water-guiding core into the rear end of the connecting sleeve, and insert the water-guiding fiber into the water-guiding core. Finally, the overlapping part of the connecting sleeve and the water-guiding core is deformed so that the two cannot be separated, thus completing the assembly of the direct-liquid pen refill assembly. Compared with traditional manual assembly, the assembly efficiency and accuracy are higher, that is, the yield rate is improved. It not only has high assembly efficiency, but also significantly improves the product qualification rate, which is conducive to mass production and can bring good economic benefits to enterprises.

[0006] The invention is further configured such that the transmission device includes a motor, a main shaft, a divider, a turntable, and multiple gripper assemblies. The main shaft is rotatably mounted within a frame. The output end of the motor is linked to the main shaft via a first belt drive assembly to drive the main shaft to rotate. The main shaft is linked to the input end of the divider via a chain drive assembly. The turntable is mounted on the output end of the divider. Multiple gripper assemblies are evenly distributed circumferentially around the outer periphery of the turntable. A fixed plate is also fixedly mounted above the turntable. The fixed plate has multiple inspection ports for inserting tools to inspect the corresponding gripper assemblies. Each gripper assembly includes a gripper base, a gripper body, and a gripper spring. The gripper base is mounted on the side of the turntable. The gripper body is axially telescopically disposed within the gripper seat. The inner end of the gripper body has a force-receiving part extending outward. The gripper seat is provided with a limiting member for limiting the outer travel of the gripper body. The gripper spring is sleeved on the outer periphery of the gripper body, and both ends of the gripper spring abut against the limiting member and the force-receiving part, respectively. The outer end of the gripper body has a tapered clamping end that is smaller in the inner part and larger in the outer part. The tapered clamping end includes multiple claw blocks arranged in a circumferential array. There is a contraction gap between two adjacent claw blocks, and a clamping channel for clamping the pen tip is provided at the center of the multiple claw blocks. The gripper body is also provided with a positioning head for positioning the pen tip, and the positioning head is linked to the limiting member by a screw.

[0007] By adopting the above technical solution, the motor is used as the prime mover to drive the turntable to rotate multiple gripper assemblies, realizing uninterrupted assembly at multiple workstations. The gripper body causes multiple claw blocks to deform inward or expand back to their original position by extending and retracting along the axial direction, thereby realizing the gripping or releasing of materials.

[0008] The invention is further configured such that the transmission device includes two sets of drive assemblies for respectively causing the gripper assemblies cooperating with the pen tip feeding device and the discharging device to open, and the drive assemblies are linked to the main shaft through a cam transmission assembly; the drive assembly includes a guide sleeve, a drive rod, and a first reset member, the guide sleeve is fixedly disposed in the fixed disk, the drive rod is axially movable in the guide sleeve, one end of the first reset member is connected to the inside of the fixed disk, and the other end of the first reset member is connected to the drive rod, so that the drive rod has a tendency to move away from the corresponding gripper assembly; the cam transmission assembly includes a transmission cam, a fixed rod, a swing rod, and a movable... The moving rod and the rod spring are connected. The transmission cam is mounted on the main shaft. The moving rod is vertically movably mounted on the frame. The fixed rod is fixedly mounted inside the frame. One end of the swing rod is hinged to the fixed rod. The middle part of the swing rod abuts against the upper part of the transmission cam. The upper part of the other end of the swing rod abuts against the bottom end of the moving rod. A spring support ring is provided on the outer periphery of the moving rod. The rod spring is sleeved on the outer periphery of the moving rod, and both ends of the rod spring abut against the spring support ring and the frame, respectively. The upper end of the moving rod is provided with a tapered mating part that is smaller at the top and larger at the bottom. The inner end of the drive rod abuts against the tapered mating part. When the moving rod moves vertically, the drive rod moves axially inward or outward.

[0009] By adopting the above technical solution, when the gripper assembly faces the pen tip feeding device or the discharging device, the movable rod of the cam transmission assembly moves upward, pushing the drive rod outward, causing the multiple claw blocks on the gripper body to open, performing the action of gripping the pen tip or releasing the pen refill assembly. When the gripper assembly leaves the assembly position of the pen tip feeding device or the discharging device, the movable rod moves downward, and the drive rod returns to its original position under the action of the first reset component. The multiple claws on the gripper body retract to clamp the pen tip or perform the next round of assembly.

[0010] The invention is further configured such that the pen tip feeding device includes a pen tip vibrating plate, a first support, a first cylinder, a first slider, a pen tip guide block, a switching element, a torsion spring, and a limiting block. The first cylinder is mounted on the first support, and its extended end is linked to the first slider to drive the first slider to move towards or away from the turntable. The pen tip guide block is mounted on the first slider and has a pen tip feeding channel for pen tips to pass through. The output end of the pen tip vibrating plate is connected to the pen tip feeding channel via a conduit. The switching element is rotated by a connecting screw. The on / off element is located on the side of the pen tip guide block. It has a linkage part and a blocking part. The torsion spring is sleeved on the connecting screw, and the two ends of the torsion spring abut against the linkage part and the blocking part, respectively. The limiting block is installed on the fixed plate. When the first slider moves towards the turntable under the drive of the first cylinder and the linkage part abuts against the limiting block, the on / off element rotates to make the blocking part leave the pen tip feeding channel. When the first slider moves away from the turntable under the drive of the first cylinder, the on / off element reverses under the action of the torsion spring, making the blocking part move and block the outer end of the pen tip feeding channel.

[0011] By adopting the above technical solution, pen tips can be inserted one by one into the clamping channel of the gripper assembly.

[0012] The invention is further configured such that the water-guiding fiber assembly device includes a discharge mechanism, a feeding mechanism, and a cutting mechanism. The discharge mechanism includes a first drive motor, a first bearing seat, a first transmission shaft, and a material tray. The first transmission shaft is rotatably mounted on the first bearing seat. The motor shaft of the first drive motor is linked to the first transmission shaft via a second belt transmission assembly. The material tray is linkedly mounted on the first transmission shaft for unwinding the water-guiding fiber. The feeding mechanism includes a feeding seat, a first rotating shaft, a second rotating shaft, a first feeding tray, a second feeding tray, a third cylinder, and a ratchet and pawl transmission assembly. The first rotating shaft is rotatably mounted on the feeding seat. The first feeding tray is linkedly mounted on the upper end of the first rotating shaft. A movable pressure block is slidably mounted on the feeding seat along the direction close to or away from the first rotating shaft. A pressure block spring is provided on the feeding seat to act on the movable pressure block, causing the movable pressure block to have a tendency to move towards the first rotating shaft. The second rotating shaft is rotatably mounted on the movable pressure block. The second feeding tray is linkedly mounted on the upper end of the second rotating shaft. The water-guiding fiber passes between the first and second feeding discs, and the outer periphery of the first feeding disc is provided with an annular groove for positioning the water-guiding fiber. The feeding seat is provided with guide tubes for the water-guiding fiber to pass through, respectively, corresponding to the front and rear sides between the first and second feeding discs. The feeding seat is provided with a support arm, one end of the third cylinder is hinged to the support arm, and the other end of the third cylinder is linked to the first rotating shaft through a ratchet and pawl transmission assembly. The first rotating shaft is provided with a first gear, and the second rotating shaft is provided with a second gear that meshes with the first gear. The cutting mechanism includes a fourth cylinder mounted on a fixed disc, and a cutter for cutting the water-guiding fiber is detachably mounted on the extended end of the fourth cylinder. There are also two fixed guide rings for the water-guiding fiber to pass through between the feeding disc and the feeding seat. A movable guide ring is movably arranged vertically between the two fixed guide rings. The lower end of the movable guide ring is provided with a movable detection rod, and a proximity switch for detecting the movable detection rod is fixedly installed below the fixed guide ring.

[0013] By adopting the above technical solution, the water-guiding fiber is released from the material tray, and the third cylinder extends and retracts, driving the ratchet and pawl transmission assembly to move. This causes the first and second material trays to intermittently and quantitatively push the water-guiding fiber forward. After the front end of the water-guiding fiber is inserted into the rear end of the pen head, the fourth cylinder of the cutting mechanism drives the cutter to descend and cut the water-guiding fiber, thus realizing the assembly of the water-guiding fiber and the pen head.

[0014] The invention is further configured such that a detection device for detecting whether the pen tip is properly clamped is respectively provided at a position corresponding to the rear of the pen tip feeding device and the rear of the water-guiding fiber assembly device in the transmission direction of the transmission device; the detection device includes a second support, a second cylinder, a second slider, a proximity sensor switch and a second push rod, the second cylinder is mounted on the second support, and the extended end of the second cylinder is linked to the second slider to drive the second slider to move in a direction closer to or away from the turntable, the proximity sensor switch is mounted on the second slider, when the pen tip is not properly installed or is exposed for too long, the second push rod approaches and triggers the proximity sensor switch, causing the equipment to stop.

[0015] By adopting the above technical solution, it is possible to detect whether the pen tip is properly clamped and whether it is exposed too long.

[0016] The invention is further configured such that the connecting sleeve assembly device includes a connecting sleeve vibrating plate, a straight vibrator, a third support, a fifth cylinder, and a reversing seat. The straight vibrator is provided with a straight vibration track, one end of which is connected to the outlet end of the connecting sleeve vibrating plate, and the other end of which is connected to the reversing seat. The reversing seat is provided with an arc-shaped reversing groove connected to the straight vibration track at an angle of 90°. The fifth cylinder is mounted on the third support, and an assembly seat is provided on the extended end of the fifth cylinder. The assembly seat is slidably mounted at the bottom of the reversing seat under the action of the fifth cylinder, and the assembly seat is provided with a straight assembly groove for a connecting sleeve at the bottom of the arc-shaped reversing groove to fall into. The straight assembly groove is also provided with an assembly rod for pushing the connecting sleeve out when the assembly seat moves toward the corresponding gripper assembly.

[0017] By adopting the above technical solution, the connecting sleeve is sent out in an orderly manner by the connecting sleeve vibrating plate and the straight vibrator. The vertically placed connecting sleeve is switched to horizontal assembly one by one by the arc-shaped reversing groove on the reversing seat. When the fifth cylinder drives the assembly seat to extend, the assembly rod on the assembly seat pushes the connecting sleeve on the straight assembly groove onto the pen tip, thus completing the assembly of the pen tip and the connecting sleeve.

[0018] The invention is further configured such that the water-guiding core assembly device includes a fourth support, a sixth cylinder, a third slider, a third push rod, a water-guiding core hopper, and a discharge seat. The sixth cylinder is mounted on the fourth support, and its extended end is linked to the third slider. The third push rod is mounted on the third slider. The discharge seat is disposed on the fourth support. The discharge seat has a feeding channel running vertically from top to bottom for the water-guiding cores to be arranged one by one in the vertical direction. The discharge seat has an opening at each of its front and rear ends that communicates with the feeding channel. When the third push rod extends into the feeding channel through one of the openings, it pushes out the water-guiding core at the bottom of the feeding channel and inserts it into the corresponding connecting sleeve. The water-guiding core hopper is disposed on the upper end of the discharge seat, and the discharge port at the bottom of the water-guiding core hopper is located on the discharge seat. The fixed plate is connected to the feeding channel and has a fixed seat. A guide groove is provided on the fixed seat along the horizontal direction. The water core hopper is provided with a guide protrusion that cooperates with the guide groove. The fixed plate is provided with a second bearing seat on the side corresponding to the fixed seat. A second transmission shaft is rotatably mounted on the second bearing seat. One end of the second transmission shaft is linked to the input end of the divider through a third belt transmission assembly. The other end of the second transmission shaft is provided with a disc. A connecting rod is hinged to the disc near the edge. The end of the connecting rod away from the disc is hinged to the water core hopper, which causes the water core hopper to slide back and forth along the extension direction of the guide groove. A lifting cylinder is also provided directly below the fixed seat. A guide seat for guiding the water core is installed on the movable end of the lifting cylinder.

[0019] By adopting the above technical solution, the water inlet cores can be pushed onto the connecting sleeve one by one, and the hopper always moves back and forth in the horizontal direction, which can ensure that the water inlet cores in the hopper can be discharged smoothly without blockage. Its operation shares the same prime mover (motor) with the divider, which greatly saves energy consumption and production costs.

[0020] The invention is further configured such that the deformation device includes a lower support assembly and an upper pressing assembly. The lower support assembly includes a fifth support mounted on a frame, a seventh cylinder mounted on the fifth support, and a support seat mounted on the extended end of the seventh cylinder. The support seat has a positioning groove for supporting the pen refill assembly. The upper pressing assembly includes a sixth support mounted on a fixed plate, an eighth cylinder mounted on the sixth support, a linkage block mounted on the extended end of the eighth cylinder, a pin mounted on the linkage block and extending downward, a vertical guide rail mounted vertically on the sixth support, a vertical slider slidably mounted on the vertical guide rail, and a fixed assembly. A needle sleeve is fitted around the outer periphery of the ejector pin on a vertical slider. The upper end of the needle sleeve has a limiting flange extending outward. The linkage block can push the needle sleeve and the vertical slider downward when it moves downward. The linkage block has a fork rod that abuts against the lower end of the limiting flange when it moves upward to drag the needle sleeve and the vertical slider upward. The lower end of the vertical slider also has a needle spring acting on the upper end of the needle sleeve. In the initial state, the lower end of the ejector pin is located inside the needle sleeve. When the needle sleeve moves downward with the vertical slider and the limiting part on the vertical slider abuts against the fixed plate, the bottom end of the needle sleeve gently contacts the pen refill assembly. When the linkage block continues to drive the ejector pin downward, the bottom end of the ejector pin extends out of the needle sleeve and squeezes the pen refill assembly.

[0021] By adopting the above technical solution, the pen refill assembly is supported by the support seat of the lower support component. The eighth cylinder drives the ejector pin to move downward. The ejector pin squeezes the overlapping part of the connecting sleeve and the water-guiding core, causing the part to deform inward, so that the two cannot be separated, and finally the assembly of the pen refill assembly is completed.

[0022] The invention is further configured such that the discharge device includes a ninth cylinder disposed on a fixed plate, a finger cylinder disposed on the extended end of the ninth cylinder, and a finished product collection bin disposed below the finger cylinder.

[0023] By adopting the above technical solution, when the assembled pen refill assembly reaches the top of the finished product collection chamber, the ninth cylinder, in conjunction with the finger cylinder, clamps the pen refill assembly, while the gripper assembly releases the pen refill assembly. Then, the ninth cylinder, in conjunction with the finger cylinder, places the pen refill assembly into the finished product collection chamber. Attached Figure Description

The various devices work together to automatically insert one end of the water-guiding fiber into the rear end of the pen tip, then place the front end of the connecting sleeve onto the rear end of the pen tip, then insert the water-guiding core into the rear end of the connecting sleeve, and finally insert the water-guiding fiber into the water-guiding core. Finally, the overlapping part of the connecting sleeve and the water-guiding core is deformed so that the two cannot be separated, thus completing the assembly of the direct-liquid pen refill assembly.

The upper end of the movable rod 33 is provided with a tapered mating part 36 that is smaller at the top and larger at the bottom. The inner end of the drive rod 28 abuts against the tapered mating part 36. When the movable rod 33 moves vertically, the drive rod 28 moves axially inward or outward. When the gripper assembly 13 faces the pen tip feeding device 3 or the discharging device 8, the movable rod 33 of the cam transmission assembly 26 moves upward, pushing the drive rod 28 outward, causing the multiple claw blocks 22 on the gripper body 18 to open, performing the action of gripping the pen tip or releasing the pen refill assembly. When the gripper assembly 13 leaves the assembly position of the pen tip feeding device 3 or the discharging device 8, the movable rod 33 moves downward, and the drive rod 28 returns to its original position under the action of the first reset member 29. The multiple claws on the gripper body 18 retract to clamp the pen tip or perform the next round of assembly.

[0047] As attached Figure 8 and attached Figure 9As shown, the pen tip feeding device 3 includes a pen tip vibrating plate 37, a first support 38, a first cylinder 39, a first slider 40, a pen tip guide block 41, a switch 42, a torsion spring 43, and a limiting block 44.

The pen tip guide block 41 is mounted on the first slider 40 and has a pen tip feeding channel 45 for pen tips to pass through. The output end of the pen tip vibrating plate 37 is connected to the pen tip feeding channel 45 through a conduit 46. The switch 42 is rotatably mounted on the pen tip via a connecting screw 47. On the side of the guide block 41, the switching element 42 is provided with a linkage part 48 and a blocking part 49. The torsion spring 43 is sleeved on the connecting screw 47, and the two ends of the torsion spring 43 abut against the linkage part 48 and the blocking part 49 respectively. The limiting block 44 is installed on the fixed plate 16. When the first slider 40 moves towards the turntable 12 under the drive of the first cylinder 39 and the linkage part 48 abuts against the limiting block 44, the switching element 42 rotates, causing the blocking part 49 to leave the pen tip feeding channel 45. When the first slider 40 moves away from the turntable 12 under the drive of the first cylinder 39, the switching element 42 reverses under the action of the torsion spring 43, causing the blocking part 49 to move and block the outer end of the pen tip feeding channel 45. With this device, pen tips can be inserted one by one into the clamping channel 24 of the gripper assembly 13.

[0048] As attached Figure 10 and attached Figure 11As shown, the water-guiding fiber assembly device 4 includes a discharge mechanism 50, a feeding mechanism 51, and a cutting mechanism 52. The discharge mechanism 50 includes a first drive motor 53, a first bearing seat 54, a first transmission shaft 55, and a material tray 56. The first transmission shaft 55 is rotatably mounted on the first bearing seat 54. The motor shaft of the first drive motor 53 is linked to the first transmission shaft 55 through a second belt transmission assembly 57. The material tray 56 is linkedly mounted on the first transmission shaft 55 for unwinding the water-guiding fiber. The feeding mechanism 51 includes a feeding seat 58, a first rotating shaft 59, a second rotating shaft 60, a first feeding tray 61, a second feeding tray 62, a third cylinder 63, and a ratchet and pawl transmission assembly 64. A rotating shaft 59 is rotatably mounted on a feeding seat 58. A first feeding disc 61 is linkedly mounted on the upper end of the first rotating shaft 59. A movable pressure block 65 is slidably mounted on the feeding seat 58 along the direction close to or away from the first rotating shaft 59. A pressure block spring 66 is provided on the feeding seat 58 to act on the movable pressure block 65, causing the movable pressure block 65 to have a tendency to move towards the first rotating shaft 59. A second rotating shaft 60 is rotatably mounted on the movable pressure block 65. A second feeding disc 62 is linkedly mounted on the upper end of the second rotating shaft 60. Water-guiding fibers pass between the first feeding disc 61 and the second feeding disc 62. An annular groove 67 for positioning the water-guiding fibers is provided on the outer periphery of the first feeding disc 61. The feeding seat 58 corresponds to the first feeding disc... A guide tube 68 for the water-guiding fiber to pass through is respectively provided at the front and rear of the material tray 61 and the second material feeding tray 62; the material feeding seat 58 is provided with a support arm 69, one end of the third cylinder 63 is hinged to the support arm 69, and the other end of the third cylinder 63 is linked to the first rotating shaft 59 through a ratchet and pawl transmission assembly 64 (the connection between the third cylinder 63 and the pawl of the ratchet and pawl transmission assembly 64 can be adjusted to slightly control the length of the water-guiding fiber), the first rotating shaft 59 is provided with a first gear 70, and the second rotating shaft 60 is provided with a second gear 71 that meshes with the first gear 70; the cutting mechanism 52 includes a fourth cylinder 72 mounted on the fixed plate 16, the fourth A cutter 73 for cutting water-guiding fibers is detachably mounted on the extended end of the cylinder 72; two fixed guide rings 74 for water-guiding fibers to pass through are also provided between the material tray 56 and the feeding seat 58, and a movable guide ring 75 is vertically movably arranged between the two fixed guide rings 74. A movable detection rod 76 is provided at the lower end of the movable guide ring 75, and a proximity switch 77 for detecting the movable detection rod 76 is fixedly installed below the fixed guide ring 74. When the proximity switch 77 detects the movable detection rod 76, the material tray 56 will not rotate. The water-guiding fibers will shorten during the use of the water-guiding fiber assembly device 4, causing the movable detection rod 76 to rise. When the proximity switch 77 does not detect the movable detection rod 76, the material tray 56 will rotate.The water-guiding fiber is released from the feed tray 56 and extended and retracted by the third cylinder 63, which drives the ratchet and pawl transmission assembly 64 to move. This causes the first feed tray 61 and the second feed tray 62 to intermittently and quantitatively push the water-guiding fiber forward. After the front end of the water-guiding fiber is inserted into the rear end of the pen head, the fourth cylinder 72 of the cutting mechanism 52 drives the cutter 73 to descend and cut the water-guiding fiber, thus realizing the assembly of the water-guiding fiber and the pen head.

[0049] As attached Figure 2 and attached Figure 12 As shown, a detection device 78 for detecting whether the pen tip is properly clamped is respectively installed at the position behind the pen tip feeding device 3 and the position behind the water-guiding fiber assembly device 4 in the transmission direction of the transmission device 2. The detection device 78 includes a second support 79, a second cylinder 80, a second slider 81, a proximity sensor switch 130, and a second push rod 82. The second cylinder 80 is mounted on the second support 79, and the extended end of the second cylinder 80 is linked to the second slider 81 to drive the second slider 81 to move towards or away from the turntable 12. The proximity sensor switch 130 is mounted on the second slider 81. When the pen tip is not properly installed or is exposed too far, the second push rod 82 approaches and triggers the proximity sensor switch 130, stopping the equipment. This device can detect whether the pen tip is properly clamped and whether it is exposed too far.

[0050] As attached Figure 13 As shown, the connecting sleeve assembly device 5 includes a connecting sleeve vibrating plate 83, a straight vibrator 84, a third support 85, a fifth cylinder 86, and a reversing seat 87. The straight vibrator 84 is provided with a straight vibration track 88. One end of the straight vibration track 88 is connected to the outlet end of the connecting sleeve vibrating plate 83, and the other end of the straight vibration track 88 is connected to the reversing seat 87. The reversing seat 87 is provided with an arc-shaped reversing groove 89 connected to the straight vibration track 88 at an angle of 90°. The fifth cylinder 86 is set on the third support 85. An assembly seat 90 is provided on the extended end of the fifth cylinder 86. The assembly seat 90 is slidably set at the bottom of the reversing seat 87 under the action of the fifth cylinder 86. The assembly seat 90 is provided with a straight assembly groove 91 for a connecting sleeve at the bottom of the arc-shaped reversing groove 89 to fall into. The straight assembly groove 91 is also provided with an assembly rod 92 for pushing the connecting sleeve out when the assembly seat 90 moves toward the corresponding gripper assembly 13. The connecting sleeve is sent out in an orderly manner by the connecting sleeve vibrating plate 83 and the straight vibrator 84. The vertically placed connecting sleeve is switched to horizontal assembly one by one by the arc-shaped reversing groove 89 on the reversing seat 87. When the fifth cylinder drives the assembly seat 90 to extend, the assembly rod 92 on the assembly seat 90 pushes the connecting sleeve on the straight assembly groove 91 onto the pen tip, thus completing the assembly of the pen tip and the connecting sleeve.

[0051] As attached Figures 14-16As shown, the water core assembly device 6 includes a fourth support 93, a sixth cylinder 94, a third slider 95, a third push rod 96, a water core hopper 97, and a discharge seat 98. The sixth cylinder 94 is mounted on the fourth support 93, and its extended end is linked to the third slider 95. The third push rod 96 is mounted on the third slider 95. The discharge seat 98 is located on the fourth support 93 and is a detachable structure with a detachable side plate for easy maintenance. A feeding channel 99 is provided vertically from top to bottom on the discharge seat 98 for the water cores to be arranged one by one in the vertical direction. The discharge seat 98 has an opening 100 at each end that communicates with the feeding channel 99. When the third push rod 96 extends into the feeding channel 99 through one of the openings 100, it pushes out the bottommost water core of the feeding channel 99 and inserts it into the corresponding connecting sleeve. The water core hopper 97 is located on the upper end of the discharge seat 98, and the discharge port at the bottom of the water core hopper 97 is connected to the feeding channel 99. The fixed disk 16 is provided with a fixed seat 101, and a guide groove 102 is provided on the fixed seat 101 along the transverse direction. The water core hopper 97 is provided with a guide protrusion 103 (i.e., a slider element) that cooperates with the guide groove 102. The fixed disk 16 is provided with a second bearing seat 104 on the side corresponding to the fixed seat 101. A second drive shaft 105 is rotatably mounted on the second bearing seat 104. One end of the second drive shaft 105 is linked to the input end of the divider 11 through a third belt drive assembly 106. Next, a disc 107 is provided at the other end of the second drive shaft 105. A connecting rod 108 (an eccentric rotating structure) is hinged (fisheye head) near the edge of the disc 107. The end of the connecting rod 108 away from the disc 107 is hinged to the water core hopper 97, causing the water core hopper 97 to slide back and forth along the extension direction of the guide groove 102. A lifting cylinder 131 is also provided directly below the fixed base 101. A guide seat 132 for guiding the water core is installed on the movable end of the lifting cylinder 131. When the sixth cylinder 94 pushes out, the guide seat 132 for guiding the water core must rise, and when the sixth cylinder 94 retracts, the guide seat 132 for guiding the water core must fall to prevent the water core from getting stuck when the gripper assembly 13 rotates. This device can push the water cores one by one onto the connecting sleeve, and the hopper always moves back and forth in the horizontal direction, which can ensure that the water cores in the hopper can be discharged smoothly without blockage. Its operation shares the same prime mover (motor 9) with the divider 11, which greatly saves energy consumption and production costs.

[0052] As attached Figure 17As shown, the deformation device 7 includes a lower support assembly 109 and an upper pressing assembly 110. The lower support assembly 109 includes a fifth support 111 mounted on the frame 1, a seventh cylinder 112 mounted on the fifth support 111, and a support base 113 mounted on the extended end of the seventh cylinder 112. The support base 113 is provided with a positioning groove 114 for supporting the pen refill assembly. The upper pressing assembly 110 includes a sixth support 115 mounted on the fixed plate 16, an eighth cylinder 116 mounted on the sixth support 115, and a support mounted on the first... The system includes a linkage block 117 on the extended end of the eight-cylinder 116, a ejector pin 118 mounted on the linkage block 117 and extending downwards, a vertical guide rail 119 mounted vertically on the sixth support 115, a vertical slider 120 slidably mounted on the vertical guide rail 119, and a needle sleeve 121 fixedly mounted on the vertical slider 120 and sleeved around the ejector pin 118. The upper end of the needle sleeve 121 has a limiting flange 122 extending outwards. The downward movement of the linkage block 117 can push the needle sleeve 121 and the vertical slider 120 downwards. The linkage block 117 is equipped with... A fork 123, which abuts against the lower end of the limiting flange 122 during upward movement, is used to drag the needle sleeve 121 and the vertical slider 120 upward. The lower end of the vertical slider 120 is also provided with a needle spring 124 acting on the upper end of the needle sleeve 121. In the initial state, the lower end of the ejector pin 118 is located inside the needle sleeve 121. When the needle sleeve 121 moves downward with the vertical slider 120 and the limiting part on the vertical slider 120 abuts against the fixed plate 16 (i.e., when the attribute slider 120 reaches the limiting position), the bottom end of the needle sleeve 121 gently contacts the pen refill assembly (this design is for the ejector pin 118). When the needle is withdrawn, the needle sleeve 121 holds the pen refill assembly in place and is not pulled up by the ejector pin 118. When the linkage block 117 continues to drive the ejector pin 118 downward, the bottom end of the ejector pin 118 extends out of the needle sleeve 121 and squeezes the pen refill assembly. After squeezing the pen refill assembly, the eighth cylinder 118 retracts the needle spring 124 and first pushes the linkage block 117 upward. The linkage block 117 then drives the ejector pin 118 upward and retracts into the needle sleeve 121. Then, the eighth cylinder 118 drives the linkage block 117, the ejector pin 118, the vertical slider 120, and the needle sleeve 121 upward, and the needle sleeve disengages from the pen refill assembly. The pen refill assembly is supported by the support seat 113 of the lower support component 109. The eighth cylinder 116 drives the ejector pin 118 downward. The ejector pin 118 presses the overlapping part of the connecting sleeve and the water inlet core, causing the part to deform inward, so that the two cannot be separated, and finally the assembly of the pen refill assembly is completed. More specifically, when the eighth cylinder 116 presses down, the vertical slider 120 is not at the limit and the ejector pin 118 will not extend. When the vertical slider 120 reaches the limit needle sleeve 121 and just contacts the connecting sleeve, the ejector pin 118 will pierce out. Then the eighth cylinder 116 retracts the needle sleeve 121 and does not move. The ejector pin 118 will retract first. When the ejector pin 118 retracts to the bottom, the limit flange 122 and the fork 123 just contact each other.

[0053] As attached Figure 18 As shown, the discharge device 8 includes a ninth cylinder 125 mounted on a fixed plate 16, a finger cylinder 126 mounted on the extended end of the ninth cylinder 125, and a finished product collection bin 127 located below the finger cylinder 126. When the assembled pen refill assembly reaches above the finished product collection bin 127, the ninth cylinder 125, in conjunction with the finger cylinder 126, clamps the pen refill assembly, while the gripper assembly 13 releases the pen refill assembly. Then, the ninth cylinder 125, in conjunction with the finger cylinder 126, places the pen refill assembly into the finished product collection bin 127.
