Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0031] See Figures 1 to 46 As shown, this embodiment of the present disclosure provides an automatic pencil assembly device, including a frame 10, a turntable 20, a lifting device 30, a first conveying device 40, a first picking device 50, a second conveying device 60, and a second picking device 70. The turntable 20 is mounted on the frame 10 and can rotate relative to the frame 10 around its own axis. The turntable 20 has a plurality of pencil mounting positions 211 for supporting pencil barrels 1 arranged circumferentially. The lifting device 30 is mounted on the frame 10 and is located below the turntable 20. The first conveying device 40 is used to convey locking rings 2, wherein the end of the locking ring 2 with a larger diameter faces upward. The first material handling device 50 is located on the outer periphery of the turntable 20 and is connected to the lifting device 30. It is used to install the locking ring 2 in the first conveying device 40 onto the pen barrel 1 in the pen barrel mounting position 211. The second conveying device 60 is used to convey the chuck 3, wherein the insertion rod 310 of the chuck 3 faces upward. The second material handling device 70 is located on the outer periphery of the turntable 20 and is located downstream of the first material handling device 50 in the rotation direction of the turntable 20. The second material handling device 70 is connected to the lifting device 30 and is used to flip the chuck 3 in the second conveying device 60 to a set angle and install it onto the locking ring 2.

[0032] In the automatic pencil assembly equipment provided in this embodiment, during use, the turntable 20 rotates relative to the frame 10 around its own axis, so that each pencil mounting position 211 passes sequentially through the first picking device 50 and the second picking device 70. A pencil 1 is placed in the pencil mounting position 211. The locking ring 2 conveyed by the first conveying device 40 has its larger diameter end facing upward. The lifting device 30 drives the first picking device 50 to rise, so as to take out the locking ring 2 from the first conveying device 40. The lifting device 30 can also drive the first picking device 50 to fall, so as to install the taken-out locking ring 2 onto the pencil 1 that has moved with the turntable 2 to below the first picking device 50. The turntable 20 continues to rotate, driving the pencil 1 with the locking ring 2 to move to below the second picking device 70. The second picking device 70 flips the chuck 3 in the second conveying device 60 to a set angle and installs it on the locking ring 2. At this time, the turntable 20 drives the next pen barrel mounting position 211 with the pen barrel 1 to move to the bottom of the first material picking device 50. The first material picking device 50 takes out the next locking ring 2 from the first conveying device 40 and installs it on the corresponding pen barrel 1. This process is repeated to achieve continuous assembly. At the same time, there is no need for manual identification of the installation direction of the locking ring 2 and the clamp 3, which improves the assembly efficiency.

See also Figure 1 and combined Figure 45 and Figure 46 As shown in the embodiments of this disclosure, the automatic pencil assembly equipment also includes a pencil barrel feeding device 80, a pencil barrel picking device 90, a pencil barrel detection device 100, a pencil barrel positioning device 200, a pencil barrel positioning detection device 300, a locking ring detection device 500, a chuck detection device 700, a chuck fixing device 600, a good product picking device 800, and a defective product picking device 1000.

[0034] See Figure 1 As shown, taking the position of the pen barrel feeding device 90 as the starting point, in the rotation direction of the turntable 20 (with... Figure 1(Indicated by the arrow M in the image) The pen barrel detection device 100, pen barrel positioning device 200, pen barrel positioning detection device 300, first picking device 50, locking ring detection device 500, second picking device 70, chuck detection device 700, chuck fixing device 600, good product picking device 800, and defective product picking device 1000 are arranged in sequence. The pen barrel feeding device 80 is located on the side of the pen barrel picking device 90 away from the turntable 20, the first conveying device 40 is located on the side of the first picking device 50 away from the turntable 20, and the second conveying device 60 is located on the side of the second picking device 70 away from the turntable 20.

[0035] See also Figure 1 As shown, the automatic pencil assembly equipment also includes a chuck positioning detection component 1100 and an operation panel 900. The chuck positioning detection component 1100 is located between the chuck fixing device 600 and the good product picking device 800. The operation panel 900 is generally located between the first conveying device 40 and the pencil barrel feeding device 80, so as to make reasonable use of the space of the frame 10.

[0036] In some embodiments, see Figure 2 and Figure 4 As shown, the frame 10 includes a frame body 11 and an assembly table 12. An electrical box 111 is located on one side of the frame body 11 for supplying power to the equipment. The assembly table 12 is fixedly mounted on the frame body 11 and is equipped with an intermittent divider 121. The intermittent divider 121 converts continuous input motion (e.g., continuous motor rotation) into intermittent output motion. After the turntable rotates to a set angle, it ensures precise positioning and locking, maintaining stability during the stopping phase for convenient processing or operation. For example, the lifting device 30 lowers the first material handling device 50 to install the removed locking ring 2 onto the pen barrel. The turntable 20 is located above the assembly table 12. Multiple sets of support portions 21 are evenly spaced around the turntable 20. Exemplarily, each set of support portions 21 includes two pen barrel mounting positions 211, each with mounting holes. In this embodiment, the number of support portions 21 can be 16 sets, but is not limited to this.

[0037] In some embodiments, see Figure 3As shown, the lifting device 30 includes a first motor 35, a first drive shaft 31, a second drive shaft 32, a third drive shaft 33, and a fourth drive shaft 34. The first motor 35 is connected to the first drive shaft 31, the first drive shaft 31 is connected to the second drive shaft 32, the second drive shaft 32 is connected to the third drive shaft 33, and the third drive shaft 33 is connected to the fourth drive shaft 34. The second drive shaft 32 is provided with a first cam 321 and a second cam 322, and the third drive shaft 33 is provided with a third cam 331 and a fourth cam 332. The first cam 321 is connected to the second material handling device 70 through the first lifting shaft 301, the second cam 322 is connected to the chuck fixing device 600 through the second lifting shaft 302, the third cam 331 is connected to the first material handling device 50 through the third lifting shaft 303, and the fourth cam 332 is connected to the locking ring detection device 500 through the fourth lifting shaft 304.

[0038] The first drive shaft 31 is provided with a fifth cam 311 and a sixth cam 312. The fifth cam 311 is connected to the good product picking device 800 through the fifth lifting shaft 305, and the sixth cam 312 is connected to the defective product picking device 1000 through the sixth lifting shaft 306.

[0039] The fourth drive shaft 34 is equipped with a seventh cam 341 and an eighth cam 342. The seventh cam 341 is connected to the pen barrel picking device 90 through the seventh lifting shaft 307, and the eighth cam 342 is connected to the pen barrel positioning device 200 through the eighth lifting shaft 308.

[0040] The lifting device 30 is installed below the assembly table 12, which is provided with through holes for the first lifting shaft 301, the second lifting shaft 302, the third lifting shaft 303, the fourth lifting shaft 304, the fifth lifting shaft 305, the sixth lifting shaft 306, the seventh lifting shaft 307 and the eighth lifting shaft 308 to pass through.

[0041] For example, the lifting device 30 also includes a reducer 36 and an encoder 38. The first motor 35 is connected to the reducer 36 via a pulley transmission assembly. The reducer 36 is connected to the first drive shaft 31 via a first sprocket and chain transmission assembly 371. The first drive shaft 31 is connected to the second drive shaft 32 via a bevel gear. The second drive shaft 32 is connected to the third drive shaft 33 via a bevel gear. The third drive shaft 33 is connected to the fourth drive shaft 34 via a bevel gear. The first drive shaft 31 and the third drive shaft 33 are arranged in parallel opposite directions. The second drive shaft 32 and the fourth drive shaft 34 are arranged in parallel opposite directions.

[0042] The fourth drive shaft 34 is connected to the second sprocket and chain drive assembly 372. The second sprocket and chain drive assembly 372 is connected to the intermittent divider via the third sprocket and chain drive assembly 373. The fourth drive shaft 34 is connected to the encoder 38 via the fourth sprocket and chain drive assembly. The encoder 38 is used to measure the angle of rotation of the turntable.

[0043] In some embodiments, see Figures 5 to 11 As shown, the pen barrel feeding device 80 includes a hopper 81, a staggered feeding mechanism, and a pushing mechanism 83. The hopper 81 is provided with a partition 811 and an inclined block 812. The partition 811 is provided with a discharge channel 8111, allowing the pen barrel 1 inside the hopper 81 to move along the inclined block 812 and fall into the discharge channel 8111. The staggered feeding mechanism includes a drive assembly 821, a staggered cylinder 822, a staggered plate 823, and a discharge plate 824. The drive assembly 821 is connected to the inclined block 812 to drive the inclined block 812 to reciprocate along a first direction (represented by a double-headed arrow N). The staggered cylinder 822 is connected to the staggered plate 823, and the staggered plate 824... 3. A material discharge hole 8231 is provided; the material feeding plate 824 is located below the misalignment plate 823, and the material feeding plate 824 is provided with a placement platform 8241; the misalignment cylinder 822 has a first state and a second state. In the first state, the material discharge hole 8231 is connected to the material discharge channel 8111. In the second state, the material discharge hole 8231 is aligned with the placement platform 8241 so that the pen rod 1 in the material discharge hole 8231 falls on the placement platform 8241; the pushing mechanism 83 includes a pushing cylinder 831 and a pushing plate 834. The pushing cylinder 831 can drive the pushing plate 834 to move along the length direction of the pen rod 1 so as to push out the pen rod 1 located on the placement platform 8241.

[0044] For example, the hopper 81 is mounted on the assembly table 12 via a support frame 84. The hopper 81 includes two parallel and spaced-apart plates 8101, a connecting plate 8102 fixed to both ends of the two plates, and a connector 8103 that fixes the connecting plates 8102 together. The space between the two plates is used to accommodate the pen barrel 1. For example, the distance between the two plates can be slightly greater than the length of the pen barrel 1. Each plate has a connecting plate 8102 fixedly connected to both ends. The connector 8103 may include a pin, bolt, and nut. The outer side of the connecting plate 8102 has a slot, into which the pin is inserted and secured by the bolt and nut. The distance between the two plates is adjustable to accommodate pen barrels 1 of different lengths.

[0045] See Figure 7As shown, a guide block 813 is also provided inside the hopper 81. The guide block 813 has a guide slope 8131 and is located above the inclined block 812. The slope of the guide slope 8131 is less than that of the inclined block 812. The inclined block 812 is generally a right trapezoid in shape, and along the first direction, the width of the top surface of the inclined block 812 is less than the width of the bottom surface. In order to ensure that pen barrels 1 are placed in both pen barrel mounting positions 211, there are two sets of inclined blocks 812 and guide blocks 813. The two sets of inclined blocks are spaced apart along the first direction, and each set includes two inclined blocks 812. The two inclined blocks 812 are spaced apart along the arrangement direction of the two plates 8101. The drive assembly 821 is connected to the tilting block 812 to drive the tilting block 812 to reciprocate along the first direction. For example, the plate near the turntable 20 is provided with openings, a bracket, and a guide rail, which extends along the first direction. The drive assembly 821 may include a second motor 8211, a connecting rod 8212, a swing plate 8213, and a mounting plate 8214. The mounting plate 8214 is slidably connected to the guide rail. There can be two mounting plates 8214, each mounting plate 8214 having a set of tilting blocks 812 mounted on it. There are also two openings, corresponding one-to-one with the mounting plates 8214. The mounting plates 8214 pass through the openings. The first direction is described in the first direction. In one direction, the opening size is larger than the size of the mounting plate 8214 to facilitate the reciprocating movement of the mounting plate 8214 in the first direction. A second motor 8211 is mounted on the bracket, and the power output shaft of the second motor 8211 is hinged to one end of the connecting rod 8212. The hinge axis between the connecting rod 8212 and the power output shaft of the second motor 8211 is parallel to the axis of the power output shaft of the second motor 8211, i.e., the hinge axis is eccentrically set relative to the power output shaft. The other end of the connecting rod 8212 is hinged to a swing plate 8213, one end of which is fixedly connected to one of the mounting plates 8214, and the other end is fixedly connected to the other mounting plate 8214. When the second motor 8211 starts, it can drive the connecting rod 8212 to reciprocate in the first direction, thereby driving the swing plate 8213 to reciprocate in the first direction, and then driving the tilting block 812 to reciprocate in the first direction via the mounting plate 8214.

[0046] When the misalignment cylinder 822 is in the first state (e.g., the piston rod of the misalignment cylinder 822 is retracted), it drives the misalignment plate 823 to move, so that the dropping hole 8231 is connected to the dropping channel 8111, and the pen rod 1 in the dropping channel 8111 falls into the dropping hole 8231; when the misalignment cylinder 822 is in the second state (e.g., the piston rod of the misalignment cylinder 822 is extended), the dropping hole 8231 is aligned with the placement table 8241, so that the pen rod 1 in the dropping hole 8231 falls on the placement table 8241.

[0047] See Figure 10 and Figure 11As shown, the pushing mechanism 83 includes a pushing cylinder 831, a pushing connecting plate (not shown), a connecting block 833, and a pushing plate 834. The pushing cylinder 831 is mounted on the support frame 84. The pushing connecting plate is connected to the piston rod of the pushing cylinder 831. The connecting block 833 is connected to the pushing connecting plate. The pushing plate 834 is connected to the connecting block 833. The pushing cylinder 831 drives the pushing plate 834 to move along the length of the pen barrel 1 towards the turntable 20 via the pushing connecting plate and the connecting block 833, thereby pushing out the pen barrel 1 located on the placement table 8241. For example, see... Figure 11 As shown, the position of the pusher plate 834 on the left indicates the position after the pen barrel is pushed out. It should be understood that in the actual processing, the two pusher plates 834 push out the two pen barrels simultaneously.

[0048] In some embodiments, see Figure 12 and Figure 13 As shown, the pen barrel picking device 90 includes a linear guide rail 91, a guide plate 92, a flip mounting plate 93, a bearing seat 94, a roller bearing 95, a swinging component 96, a rotating plate 97, a first gripper cylinder 98, and a first telescopic device 99.

[0049] The linear guide 91 is connected to the seventh cam 341 via the seventh lifting shaft 307, and the extension direction of the linear guide 91 is consistent with the extension direction of the pen barrel 1. In order to ensure that the seventh lifting shaft 307 can be lifted vertically, a square base is provided on the assembly table 12, and the square base is provided with a guide rail. The seventh lifting shaft 307 is fixedly connected by a slider and a locking block, and the slider cooperates with the guide rail.

[0050] A guide plate 92 is disposed on the side of the linear guide rail 91 near the hopper 81. A guide groove is provided on the side of the guide plate 92 near the linear guide rail 91. The guide groove includes a straight groove 921 and an arc groove 922. The straight groove 921 and the arc groove 922 are smoothly transitioned to ensure smoothness during the flipping process. A flipping mounting plate 93 is mounted on the slider in the linear guide rail 91. A bearing seat 94 is mounted on the flipping mounting plate 93. A roller bearing 95 is mounted on the bearing seat 94 via a swing member 96. The roller bearing 95 can move along the guide groove. The swing member 96 is generally teardrop-shaped plate structure. The swing member 96 has two opposite arc edges with different radii. The center of the arc edge with a larger diameter is located on the axis of the bearing seat 94, and the center of the arc edge with a smaller diameter is located on the axis of the roller bearing 95. A rotating plate 97 is fixedly connected to the swing member 96, and a first gripper cylinder 98 is mounted on the rotating plate 97. The first telescopic device 99 can be, but is not limited to, a cylinder. The cylinder body is fixed to the side of the linear guide rail 91 away from the hopper 81 by a fixing member. The piston rod of the cylinder is connected to the flip mounting plate 93 to drive the slider to reciprocate along the extension direction of the guide rail. As the roller bearing 95 moves in the guide groove, it can drive the swing member 96 to rotate 90° around the axis of the bearing seat 94, thereby driving the first gripper cylinder 98 to rotate 90°. At this time, the pen barrel 1 held by the first gripper cylinder 98 rotates from a horizontal state to a vertical state. When the pen barrel 1 is aligned with the pen barrel mounting position 211, the seventh cam 341 drives the seventh lifting shaft 307 to descend, so that the pen barrel 1 enters the pen barrel mounting position 211, and then the first gripper cylinder 98 releases the pen barrel 1. For example, there can be two first gripper cylinders 98, which grip two pen barrels 1 at a time.

[0051] In some embodiments, see Figure 14As shown, the pen barrel detection device 100 includes a second mounting bracket 101, an abutment portion 102, a second detection shaft 103, a second detection ring 104, and a second proximity switch 105. The second mounting bracket 101 is connected to the lifting device 30. Specifically, the second mounting bracket 101 is connected to the eighth cam 342 via the eighth lifting shaft 308. The second detection shaft 103 is movably mounted on the second mounting bracket 101, and the abutment portion 102 is mounted on one end of the second detection shaft 103 near the pen barrel mounting position 211. The abutment portion 102 is movable relative to the second detection shaft 103. For example, the second detection shaft 103 is fitted with a first spring 106, one end of the first spring 106 abuts against the abutment portion 102, and the other end of the first spring 106 is connected to the second mounting bracket 101. 1. Abutment; The second detection ring 104 is installed at one end of the second detection shaft 103 away from the pen barrel mounting position 211, and the second proximity switch 105 is installed on the second mounting bracket 101. In the initial position, along the axial direction of the second detection shaft 103, the second proximity switch 105 is located above the second detection ring 104; The lifting device 30 can drive the second detection shaft 103 and the second proximity switch 105 to move downward together. When the abutment part 102 abuts with the pen barrel 1, the lifting device 30 drives the second detection shaft 103 to continue to move downward. When the second detection shaft 103 abuts with the pen barrel 1, the second proximity switch 105 can continue to move downward and be opposite to the second detection ring 104. At this time, the signal changes, and it can be determined that there is a pen barrel 1 in the pen barrel mounting position 211.

[0052] In some embodiments, the portion of the pen barrel 1 located at the pen barrel mounting position 211 has a specific cross-sectional profile, and the pen barrel mounting position 211 is provided with a contouring area 2111, which can be adapted to the specific cross-sectional profile. The automatic pencil assembly equipment also includes a pen barrel positioning device 200, which is located downstream of the pen barrel detection device 100 along the rotation direction of the turntable 20. The pen barrel positioning device 200 can drive the pen barrel 1 to rotate and move downward, so as to achieve installation in place by adapting the specific cross-sectional profile to the contour of the contouring area 2111.

[0053] Typically, to improve grip, the cross-sectional shape of the pen barrel 1 is not necessarily circular; for example, a specific cross-sectional profile can be elliptical. When the portion with a specific cross-sectional profile is located at the pen barrel mounting position 211, a contoured area 2111 needs to be provided at the pen barrel mounting position 211 (e.g., Figure 16 As shown in the figure, ensure that the pen barrel 1 can be installed in place to avoid the situation where the top of the pen barrel is not at the same height due to improper installation.

[0054] When the pen barrel detection device 100 determines that the pen barrel 1 is placed in the pen barrel installation position 211, the pen barrel positioning device 200 drives the pen barrel 1 to rotate. When the specific shape cross-sectional profile of the pen barrel 1 matches the profile of the contouring area 2111, the pen barrel 1 can move downward under the downward pressure of the pen barrel positioning device 200 or under the gravity of the pen barrel itself. The specific shape cross-sectional profile basically fits the profile of the contouring area 2111, thereby realizing the pen barrel installation in place.

[0055] In some embodiments, see Figure 14 and Figure 15 As shown, the pen barrel positioning device 200 includes a third drive unit 201, a rotating power shaft 202, a rotating bushing 203, and a second spring 204. The third drive unit 201 is mounted on the second mounting bracket 101 and can drive the rotating power shaft 202 to rotate. The rotating bushing 203 is mounted on one end of the rotating power shaft 202 near the pen barrel mounting position 211. The second spring 204 is sleeved on the rotating power shaft 202. One end of the second spring 204 abuts against the rotating bushing 203, and the other end of the second spring 204 abuts against the annular protrusion of the rotating power shaft 202.

[0056] For example, the third drive unit 201 includes a third telescopic device 2011, a rack 2012, and a gear 2013; the third telescopic device 2011 can be a cylinder, the cylinder body of which is fixedly mounted on the second mounting bracket 101, and the piston rod of the cylinder is indirectly connected to one end of the rack 2012. The piston rod of the cylinder extends and retracts, causing the rack 2012 to reciprocate along its length, thereby driving the gear 2013 to rotate.

[0057] In some embodiments, the rotary power shaft 202 includes a first shaft segment 2021, a second shaft segment 2022, a third shaft segment 2023, and a connecting sleeve 2024. The first shaft segment is fixedly connected to the second shaft segment via the connecting sleeve. Specifically, the end face of the first shaft segment in contact with the connecting sleeve is pressed and fixed by a compression spring 2025. One end of the second shaft segment is interference-fitted with the connecting sleeve, and the other end of the second shaft segment is fixedly connected to the third shaft segment. When the gear rotates, the first shaft segment 2021, the second shaft segment 2022, the third shaft segment 2023, and the connecting sleeve 2024 rotate together. In other embodiments, the rotary power shaft may also be an integral structure.

[0058] The rotating bushing 203 is fixedly sleeved on the outside of the third shaft segment 2023. Both the rotating bushing 203 and the third shaft segment have annular bosses. The second spring 204 is sleeved on the outer surface of the third shaft segment and a part of the rotating bushing. The two ends of the second spring 204 abut against the annular bosses of the rotating bushing 203 and the third shaft segment 2023, respectively.

[0059] The rotating bushing 203 has a flared end near the pen barrel mounting position to facilitate the upper end of the pen barrel entering the rotating bushing 203. The eighth cam 342 drives the second mounting bracket 101 to descend via the eighth lifting shaft 308. When the inner wall of the flared end abuts against the end face of the pen barrel, the rotating bushing and the pen barrel remain relatively stationary. The second mounting bracket continues to descend, and the second spring 204 is compressed and undergoes elastic deformation. At the same time, the rotating bushing drives the pen barrel to rotate together. When the specific shape cross-sectional profile of the pen barrel 1 matches the profile of the contouring area 2111, the pen barrel 1 can move downward under the elastic force of the second spring or under the gravity of the pen barrel itself. The specific shape cross-sectional profile and the profile of the contouring area 2111 are basically in contact, thereby realizing the pen barrel is installed in place.

[0060] It should be understood that when it is detected that there is no pen in the pen mounting position or the pen is not installed in place, when the pen mounting position is rotated to the subsequent working position, the corresponding device can be controlled by the solenoid valve not to perform the corresponding operation.

[0061] In some embodiments, see Figure 4 As shown, the frame 10 also includes a fixing plate 13, which is located above the turntable 20. The fixing plate 13 can be fixedly connected to the assembly table 12, and the fixing plate 13 does not rotate with the turntable 20. See also Figure 17 As shown, the pen barrel positioning detection device 300 includes a first through-beam sensor, which includes a first transmitter 3001 and a first receiver 3002 arranged horizontally at intervals. One of the first transmitter 3001 and the first receiver 3002 is mounted on the assembly table 12, and the other is mounted on the fixing plate 13. The first receiver 3002 receives the through-beam light emitted by the first transmitter 3001. Before the pen barrel 1 is installed in place, it can block the through-beam light. After the pen barrel 1 is lowered, it can avoid the through-beam light. The first through-beam sensor determines that the pen barrel 1 is installed in place based on the through-beam light received by the first receiver 3002.

[0062] In some embodiments, see Figure 18 and Figure 19 As shown, the automatic pencil assembly equipment also includes an auxiliary positioning device 400. The auxiliary positioning device 400 includes a first clamping part 401 and a second clamping part 402. The surfaces of the first clamping part 401 and the second clamping part 402 that are close to each other are provided with receiving grooves. The first clamping part 401 and the second clamping part 402 can approach each other so that the part of the pencil barrel 1 located outside the pencil barrel mounting position 211 is confined within the receiving groove.

[0063] For example, an auxiliary positioning device 400 is provided at a position corresponding to the first material handling device 50. The first clamping part 401 and the second clamping part 402 in the auxiliary positioning device 400 are respectively driven by cylinders to open or close. One of the two cylinders is connected to the assembly table 12, and the other cylinder is connected to the fixing plate 13. The first clamping part 401 and the second clamping part 402 are both located above the fixing plate 13. When the first clamping part 401 and the second clamping part 402 are closed, the portion of the pen barrel 1 located outside the pen barrel mounting position 211 can be auxiliaryly confined within the receiving grooves with two opposing openings. It should be understood that the closure of the first clamping part 401 and the second clamping part 402 means that the first clamping part 401 and the second clamping part 402 move towards each other to a position that can assist in positioning the pen barrel 1, and the first clamping part 401 and the second clamping part 402 are not necessarily in contact with each other.

[0064] In some embodiments, see Figure 21 As shown, the first conveying device 40 includes a first vibratory plate 41 and a first linear vibratory feeder 42. The first vibratory plate 41 can feed the oriented locking ring 2 into the first linear vibratory feeder 42, and the first linear vibratory feeder 42 continuously conveys the locking ring 2 to the next station.

[0065] In some embodiments, see Figure 22 As shown, the first material handling device 50 includes a first reciprocating drive mechanism 51, a material distribution section 52, a second reciprocating drive mechanism 53, and a first material handling section 54. The first reciprocating drive mechanism 51 is mounted on the frame 10, and the material distribution section 52 is connected to the first reciprocating drive mechanism 51. The material distribution section 52 is provided with a notch 521 for accommodating the locking ring 2. The first reciprocating drive mechanism 51 can drive the material distribution section 52 to move so that the notch 521 can be aligned with the discharge port of the first conveying device 40, or so that the locking ring 2 in the notch 521 is located in the material handling section. The position to be removed; the second reciprocating drive mechanism 53 is connected to the lifting device 30, and the first picking part 54 is connected to the second reciprocating drive mechanism 53. The second reciprocating drive mechanism 53 can drive the first picking part 54 to switch between the first station and the second station. At the first station, the first picking part 54 is used to remove the locking ring 2 located at the position to be removed. At the second station, the first picking part 54 is located above the pen barrel 1, and the lifting device 30 can drive the first picking part 54 to move downward to install the locking ring 2 on the pen barrel 1.

[0066] For example, the first reciprocating drive mechanism 51 can be a cylinder, or a linear reciprocating drive mechanism such as an electric push rod, hydraulic cylinder, or lead screw. The cylinder body of the first reciprocating drive mechanism 51 is fixedly installed on the assembly table 12. The piston rod of the first reciprocating drive mechanism 51 is connected to the material distribution section 52. The material distribution section 52 can be a block structure. The surface of the material distribution section 52 facing the first conveying device 40 is provided with a notch 521 for accommodating the locking ring 2. When the first reciprocating drive mechanism 51 drives the material distribution section 52 to move until the notch 521 is aligned with the discharge port of the first conveying device 40, the first conveying device 40 sends a locking ring 2 into the notch 521. Then, the first reciprocating drive mechanism 51 continues to drive the material distribution section 52 carrying the locking ring 2 to move, so that the locking ring 2 in the notch 521 is in the position to be removed.

[0067] The second reciprocating drive mechanism 53 is connected to the third cam 331 via the third lifting shaft 303. When the locking ring 2 is in the position to be removed, the second reciprocating drive mechanism 53 drives the first picking part 54 to move to the first station to align with the locking ring 2. Then, the third cam 331 drives the third lifting shaft 303 to descend, thereby driving the first picking part 54 to move closer to the locking ring 2 so as to remove the locking ring 2. Then, the third cam 331 drives the third lifting shaft 303 to rise, and the second reciprocating drive mechanism 53 drives the first picking part 54 to move to the second station to align with the top of the pen barrel 1. At this time, the third cam 331 drives the third lifting shaft 303 to descend again, thereby driving the first picking part 54 holding the locking ring 2 to move closer to the pen barrel 1 so as to install the locking ring 2 onto the pen barrel 1.

[0068] In some embodiments, see Figure 24 and Figure 25 As shown, the first material-taking unit 54 includes a material-taking rod 541 and a vacuum device (not shown in the figure). The material-taking rod 541 is provided with an air extraction channel, and the air extraction pipe of the vacuum device is connected to the air extraction channel to adsorb the locking ring 2. An air extraction hole is provided on the side wall of the material-taking rod 541, which is connected to the air extraction channel. Both ends of the material-taking rod 541 can be in a sealed state. For example, the material-taking end of the material-taking rod 541 has a necked section to facilitate insertion into the locking ring 2 and, under vacuum adsorption, to extract the locking ring 2 from the notch 521. When the locking ring 2 is inserted into the pen barrel 1, the vacuum device closes, releasing the adsorption effect on the locking ring 2.

[0069] To further ensure the rapid separation of the locking ring 2 from the picking rod 541 and its accurate installation within the pen barrel 1, the first picking part 54 also includes a third reciprocating drive mechanism 542 and a stop sleeve 543. The third reciprocating drive mechanism 542 is mounted on the second reciprocating drive mechanism 53. The stop sleeve 543 is fixedly connected to the cylinder body of the third reciprocating drive mechanism 542. The bottom of the stop sleeve 543 is provided with a through hole 5431 for the picking rod 541 to extend out. The aperture of the hole is smaller than the inner diameter of the locking ring 2; the picking rod 541 is movably installed on the stop sleeve 543, and the piston rod of the third reciprocating drive mechanism 542 can drive the picking rod 541 to extend so that the picking end of the picking rod 541 extends into the interior of the locking ring 2 and abuts against the inner wall of the locking ring 2; the piston rod of the third reciprocating drive mechanism 542 can also drive the picking rod 541 to retract so that the locking ring 2 can contact the bottom of the stop sleeve 543 and disengage from the picking rod 541.

[0070] In some embodiments, the locking ring 2 has a first end and a second end opposite to each other. The first end extends into the pen barrel 1, and the diameter of the first end is smaller than the diameter of the second end. The second end is provided with an outward flange, which contacts the open end face of the pen barrel 1, thereby limiting the position of the locking ring 2. The diameter of the constricted section of the picking rod 541 is smaller than the diameter of the second end of the locking ring 2 but larger than the diameter of the first end, to ensure that the picking rod 541 can extend into the locking ring 2 and abut against the inner wall of the locking ring 2, further reducing the risk of the locking ring 2 falling off during the movement of the first picking part 54. After the locking ring 2 is installed in the pen barrel 1, the piston rod of the third reciprocating drive mechanism 542 drives the picking rod 541 to retract. At the same time, the locking ring 2 contacts the bottom of the stop sleeve 543 and will not continue to move with the picking rod 541, thereby disengaging from the picking rod 541. It should be understood that after the locking ring 2 is installed inside the pen barrel 1, the lifting device 30 can drive the first material taking part 54 to descend, so that the stop sleeve 543 first contacts the outer flange of the locking ring 2, and then the material taking rod 541 is retracted.

[0071] In some embodiments, a boss 5411 is provided at one end of the picking rod 541 near the piston rod of the third reciprocating drive mechanism 542; the first picking part 54 further includes an elastic member 544, which is sleeved on the picking rod 541, with one end of the elastic member 544 abutting against the bottom of the stop sleeve 543 and the other end of the elastic member 544 abutting against the boss 5411; the piston rod of the third reciprocating drive mechanism 542 abuts against the picking rod 541 to drive the picking rod 541 to move and cause the elastic member 544 to undergo elastic deformation; the piston rod of the third reciprocating drive mechanism 542 retracts so that the picking rod 541 retracts under the elastic force of the elastic member 544.

[0072] By incorporating the elastic element 544, the piston rod of the third reciprocating drive mechanism 542 does not need to be connected to the pick-up rod 541, improving application flexibility. The elastic element 544 (e.g., a compression spring) can absorb shocks and vibrations. When the piston rod moves rapidly to the end of its stroke or encounters resistance during the pick-up process, the elastic element 544 acts as a buffer, reducing the impact force on the piston rod, pick-up rod 541, and locking ring 2. This effectively prevents damage to components such as the locking ring 2 and extends the service life of the equipment.

[0073] In some embodiments, see Figures 26 to 29 As shown, the locking ring detection device 500 includes a first mounting bracket 501, a detection sleeve 502, a first detection shaft 503, a first detection ring 504, and a first proximity switch 505. The first mounting bracket 501 is connected to the lifting device 30. The first detection shaft 503 is movably mounted on the first mounting bracket 501. The detection sleeve 502 is mounted on one end of the first detection shaft 503 near the pen barrel mounting position 211, and the detection sleeve 502 can move relative to the first detection shaft 503. The first detection ring 504 is mounted on one end of the first detection shaft 503 away from the pen barrel mounting position 211, and the first proximity switch 505 is mounted on the first mounting bracket 501.

[0074] Specifically, the first mounting bracket 501 includes a base plate and a support, which are fixedly connected. The base plate is connected to the fourth cam 332 via the fourth lifting shaft 304. The support includes a vertical plate, a first horizontal plate 5011, and a second horizontal plate 5012. The extension direction of the vertical plate is basically the same as the axial direction of the first detection shaft 503. Along the extension direction of the vertical plate, one end of the vertical plate is connected to the first horizontal plate 5011, and the other end is connected to the second horizontal plate 5012. The first horizontal plate 5011 is located above the second horizontal plate 5012. A first proximity switch 505 is installed on the vertical plate, and the number of first proximity switches 505 is the same as the number of pen mounting positions 211. Both the first and second horizontal plates are provided with through holes, and the first detection shaft 503 passes through the two through holes. A third spring 506 is sleeved on the first detection shaft 503, and the third spring 506 is located between the first and second horizontal plates. A first detection ring 504 is located above the first horizontal plate. The detection sleeve 502 is mounted on one end of the first detection shaft 503 near the pen barrel mounting position via a pin 5021. The first detection shaft 503 is provided with a guide groove 5031. For example, the detection sleeve 502 is provided with a through hole that penetrates the detection sleeve radially. The diameter of the through hole can be adapted to the outer diameter of the pin. The guide groove can penetrate the first detection shaft radially so that the pin can pass through the through hole and the guide groove and be fixed by a snap ring. The guide groove extends axially along the first detection shaft so that the first detection shaft can rise or fall relative to the detection sleeve and the pin.

[0075] In the initial position, along the axial direction of the first detection shaft 503, the first proximity switch 505 is located above the first detection ring 504; the rotation of the fourth cam 332 can drive the fourth lifting shaft 304 to move downward, thereby driving the first detection shaft 503 and the first proximity switch 505 to move downward together. When the first detection shaft 503 abuts against the inner wall of the locking ring 2, the fourth lifting shaft 304 continues to move downward. At this time, the third spring 506 is compressed, the first proximity switch 505 continues to move downward and is opposite to the first detection ring 504. At this time, the signal changes, which can determine that the locking ring 2 is installed inside the pen barrel 1.

[0076] In some embodiments, an auxiliary positioning device 400' is provided at a position corresponding to the locking ring detection device 500. The structure and working principle of the auxiliary positioning device 400' are the same as those of the auxiliary positioning device 400, and will not be described again here.

[0077] In some embodiments, see Figure 30 and Figure 31 As shown, the second conveying device 60 includes a second vibratory plate 61 and a second linear vibratory feeder 62. The second vibratory plate 61 can feed the oriented clamp 3 into the second linear vibratory feeder 62, and the second linear vibratory feeder 62 continuously conveys the clamp 3 to the next station. A partition is provided on the linear conveying track of the second linear vibratory feeder 62. The clamp 3 has two elastic branches 320, which are located on both sides of the partition, and the partition supports the clamp 3.

[0078] It should be understood that the structure and working principle of the first vibratory feeder 41, the first linear vibratory feeder 42, the second vibratory feeder 61, and the second linear vibratory feeder 62 are all things that should be understood by those skilled in the art, and are well known and easy to implement for those skilled in the art. Therefore, this embodiment will not describe them in detail.

[0079] In some embodiments, see Figures 31 to 35 As shown, the second material handling device 70 includes a fourth reciprocating drive mechanism 71, a first clamping part 72, a flipping mechanism 73, and a second clamping part 74. The fourth reciprocating drive mechanism 71 is connected to the lifting device 30. The first clamping part 72 is installed on the fourth reciprocating drive mechanism 71 and is used to place the clamp 3 in the second conveying device 60 into the flipping mechanism 73. The insertion rod 310 of the clamp 3 in the second conveying device 60 faces upward. The flipping mechanism 73 can rotate 180° so that the insertion rod 310 of the clamp 3 faces downward. The second clamping part 74 is connected to the lifting device 30 and is used to place the clamp 3 in the flipping mechanism 73 into the locking ring 2.

[0080] For example, the fourth reciprocating drive mechanism 71 may include a linear guide rail, which is connected to the first cam 321 via a first lifting shaft 301. Both the first gripping portion 72 and the second gripping portion 74 are connected to the linear guide rail, with the second gripping portion 74 located on the side of the first gripping portion 72 closer to the turntable 20. Both the first gripping portion 72 and the second gripping portion 74 may include a gripper cylinder. The first gripping portion 72 and the second gripping portion 74 can rise or fall simultaneously under the drive of the first lifting shaft 301, or they can move simultaneously in the same direction under the drive of the fourth reciprocating drive mechanism 71. To facilitate gripping different parts of the chuck, the opening and closing directions of the jaws of the first gripping part 72 and the second gripping part 74 are different. For example, the opening and closing directions of the jaws of the first gripping part 72 and the second gripping part 74 are perpendicular. The opening and closing direction of the jaws of the first gripping part 72 is consistent with the extension and retraction direction of the fourth reciprocating drive mechanism 71, and the opening and closing direction of the jaws of the second gripping part 74 is perpendicular to the extension and retraction direction of the fourth reciprocating drive mechanism 71.

[0081] In some embodiments, the flipping mechanism 73 includes a first driving part 731 and a flipping part 732. The first driving part 731 can drive the flipping part 732 to rotate 180° around a set axis. The flipping part 732 is provided with a placement cavity 7321. Along the movement direction of the lifting device 30, the placement cavity 7321 has a first end and a second end. Along the extension direction of the set axis, the size of the first end is larger than the size of the second end. The first clamping part 72 is used to put the clamp 3 into the placement cavity 7321 from the first end, wherein the elastic branch portion 320 of the clamp 3 abuts against the cavity wall of the placement cavity 7321.

[0082] The first drive unit 731 can be a rotary cylinder, and the output shaft of the rotary cylinder is connected to the tilting unit 732 for transmission. The axis is set as the axis of the output shaft of the rotary cylinder. The tilting unit 732 can include two halves, each half of which is provided with two guide grooves. The width of the guide grooves gradually decreases from one end to the other end. The two groove walls of the guide grooves are inclined relative to the extension direction of the guide grooves. The two halves are fastened together, and the two guide grooves on one half correspond one-to-one with the two guide grooves on the other half to form a placement cavity 7321. The groove walls and bottoms of the guide grooves together form the cavity wall of the placement cavity 7321. The first clamping part 72 clamps the insertion rod 310 of the chuck 3 in the second linear vibrating feeder 62. The fourth reciprocating drive mechanism 71 drives the first clamping part 72 to move above the placement cavity 7321. The lifting device 30 drives the first clamping part 72 to descend. The first clamping part 72 places the chuck 3 in the placement cavity 7321. Figure 34AAs shown. The elastic branch 320 of the chuck 3 abuts against the groove wall of the guide groove, thereby fixing it within the guide groove. It should be noted that, along the arrangement direction of the two halves, the size of the elastic branch 320 is larger than the size of the placement cavity. For example, the structures of the two halves can be different, with one half having an extension plate whose thickness is less than that of the half. The guide groove extends to the extension plate, therefore, the thickness of the groove wall of the guide groove located on the extension plate is smaller, ensuring that the elastic branch 320 of the chuck can be exposed and protrude, facilitating the second gripping part 74 to clamp the elastic branch 320.

[0083] At this time, see Figure 34B As shown, the first drive unit 731 drives the flipping unit 732 to rotate 180° around a set axis, so that the elastic branch portion 320 of the chuck faces the second gripping unit 74. The two grippers of the second gripping unit 74 are distributed along the arrangement direction of the two halves. Since the size of the elastic branch portion 320 is larger than the size of the placement cavity, it is ensured that the two grippers of the second gripping unit 74 can clamp the elastic branch portion 320. At this time, the lifting device drives the second gripping unit and the first gripping unit to rise. The second gripping unit takes out the chuck from the placement cavity, and at the same time, the first gripping unit can take out the chuck from the second linear vibrating feeder 62. Then, the first drive unit 731 drives the flipping unit 732 to rotate 180° around the set axis, so that the first end of the placement cavity 7321 faces upward; the fourth reciprocating drive mechanism 71 drives the second clamping unit and the first clamping unit to move together towards the turntable, the second clamping unit moves the chuck above the pen barrel, and the first clamping unit moves the chuck above the flipping unit 732; the lifting device drives the second clamping unit and the first clamping unit to descend, the jaws of the second clamping unit loosen, the insertion rod of the chuck falls into the locking ring in the pen barrel, the first clamping unit drives the chuck into the placement cavity, and the elastic branch 320 of the chuck 3 abuts against the groove wall of the guide groove. This reciprocating motion enables a continuous feeding and installation process for the chuck.

[0084] It should be noted that, Figure 34B In the middle, the chuck 3 in the flipping part 732 is to show the state of the chuck in the placement cavity. In actual operation, when the second gripping part 74 takes out the chuck in the flipping part 732, there is no chuck in the placement cavity.

[0085] In some embodiments, an auxiliary positioning device 400'' is provided at a position corresponding to the second material handling device 70. The structure of the auxiliary positioning device 400'' is the same as the working principle of the auxiliary positioning device 400, and will not be described again here. The structure is slightly different; see [link to relevant documentation]. Figure 33 As shown, the auxiliary positioning device 400'' has a guide flare 401'', which facilitates the retraction of the elastic branch.

[0086] In some embodiments, the chuck detection device 700 is located circumferentially between the second material handling device 70 and the chuck fixing device 600 along the turntable 20, and is used to detect whether a chuck 3 is installed inside the locking ring 2. For example, see... Figure 1 As shown, the clamp detection device 700 includes a beam sensor, which includes a second transmitter 701 and a second receiver 702 arranged horizontally at intervals. The second receiver 702 receives the beam emitted by the second transmitter 701. The clamp 3 can block the beam. The beam sensor determines that the clamp 3 is installed in the locking ring 2 based on the fact that the second receiver 702 does not receive the beam.

[0087] In some embodiments, see Figure 1 As shown, the chuck fixing device 600 is located on the outer periphery of the turntable 20, and in the rotation direction of the turntable 20, the chuck fixing device 600 is located downstream of the second material handling device 70. The chuck fixing device 600 is used to fix the insertion rod 310 of the chuck 3 to the snap member inside the pen barrel 1, and to make the elastic branch 320 of the chuck 3 retract into the locking ring 2.

[0088] After the second clamping part 74 places the clamp 3 inside the locking ring 2, the turntable 20 continues to rotate, conveying the pen barrel 1 with the clamp 3 and locking ring 2 installed to the lower part of the clamp fixing device 600. The clamp fixing device 600 drives the clamp 3 to move downward, so that the insert 310 is fixed on the snap member inside the pen barrel 1, and at the same time, the elastic branch 320 of the clamp 3 undergoes elastic deformation and retracts into the locking ring 2.

[0089] It should be noted that a core storage tube is also installed inside the pen barrel 1. The core storage tube and the snap fastener can be pre-installed in the pen barrel 1 in the previous process. The core storage tube is connected to the snap fastener. That is to say, in the pen barrel mounting position 211 of this embodiment, the pen barrel 1 is equipped with a snap fastener and a core storage tube, and the core storage tube is located below the snap fastener. The core storage tube, the snap fastener, and their connection method should be understandable to those skilled in the art, and are well known and easily implemented by those skilled in the art. Therefore, they will not be described in detail in this embodiment.

[0090] In some embodiments, see Figures 36 to 40As shown, the clamp fixing device 600 includes a second drive unit 601, a tightening sleeve 602, a fifth reciprocating drive mechanism 603, and a pressure rod 604. The second drive unit 601 and the fifth reciprocating drive mechanism 603 are both connected to the lifting device 30. The second drive unit 601 can drive the tightening sleeve 602 to rotate around its own axis. The end of the tightening sleeve 602 near the clamp 3 is provided with a frustum-shaped recess 6021. The end of the frustum-shaped recess 6021 with a larger opening is close to the clamp 3. The lifting device 30 can drive the surface of the frustum-shaped recess 6021 to contact the elastic branch 320 of the clamp 3, so that the elastic branch 320 retracts inward. The pressure rod 604 passes through the tightening sleeve 602. The fifth reciprocating drive mechanism 603 can drive the pressure rod 604 to move downward, so as to fix the insertion rod 310 of the clamp 3 onto the snap member inside the pen barrel 1.

[0091] For example, both the fifth reciprocating drive mechanism 603 and the second drive unit 601 are connected to the second lifting shaft 302 via the third mounting bracket 605, and then connected to the second cam 322 via the second lifting shaft 302. The fifth reciprocating drive mechanism 603 can be a cylinder, an electric cylinder, or other linear reciprocating drive mechanism. The second drive shaft 32 rotates, causing the second cam 322 to rotate, which in turn causes the second lifting shaft 302 to descend, causing the second drive unit 601, the tightening sleeve 602, the fifth reciprocating drive mechanism 603, and the pressure rod 604 to descend together. At this time, the surface of the frustum-shaped recess 6021 contacts the elastic branch 320 of the chuck 3. Simultaneously, the second drive unit 601 drives the tightening sleeve 602 to rotate around its own axis. That is, the tightening sleeve 602 rotates and descends at the same time, and the surface of the frustum-shaped recess 6021 can apply an inward contracting force to the elastic branch 320 of the chuck 3, causing the elastic branch 320 to undergo elastic deformation and contract inward. The fifth reciprocating drive mechanism 603 drives the pressure rod 604 to move downward. The pressure rod 604 pushes the chuck 3 downward to fix the insertion rod 310 of the chuck 3 onto the snap member inside the pen barrel 1. The elastic branch 320 can be retracted into the locking ring 2.

[0092] In some embodiments, see Figure 38 and Figure 40 As shown, the second drive unit 601 includes a telescopic device, named the second telescopic device 6011, and also includes a rack 6012 and a gear 6013. The cylinder of the second telescopic device 6011 is connected to the lifting device 30, the piston rod of the second telescopic device 6011 is connected to the rack 6012, the gear 6013 meshes with the rack 6012, and the tightening sleeve 602 is fixedly connected to the gear 6013 and coaxially arranged.

[0093] For example, the second telescopic device 6011 can be a cylinder, the cylinder body of which is mounted on the third mounting bracket 605. The piston rod of the cylinder is fixedly connected to the rack 6012 via an adapter. The gear 6013 can be mounted on the third mounting bracket 605. Specifically, the third mounting bracket 605 is provided with a mounting part, which has a cavity for the pressure rod 604 to pass through. The gear 6013 is mounted on the mounting part via a rotating shaft located inside the cavity. The rotating shaft has a hollow structure to allow the pressure rod 604 to pass through. The tightening sleeve 602 is fixedly connected to the gear 6013 and coaxially arranged. The tightening sleeve 602 is located below the gear 6013.

[0094] In some embodiments, see Figure 41 and Figure 42 As shown, the good product picking device 800 includes a sixth reciprocating drive mechanism 801, a gripper cylinder, and a rotating mechanism. The sixth reciprocating drive mechanism 801 is connected to the lifting device 30. The gripper cylinder is installed on the sixth reciprocating drive mechanism 801 and is used to grip the good product component on the pen barrel mounting position 211. The rotating mechanism is connected to the gripper cylinder to drive the gripper cylinder to rotate by a preset angle. The gripper cylinder can release the good product component after rotating by the preset angle so that the good product component falls into the good product receiving seat.

[0095] The sixth reciprocating drive mechanism 801 is connected to the fifth lifting shaft 305 via the fourth mounting bracket 803. The fifth lifting shaft 305 is connected to the fifth cam 311. When the first transmission shaft 31 rotates, it drives the fifth lifting shaft 305 to rise or fall via the fifth cam 311, thereby driving the sixth reciprocating drive mechanism 801 to rise or fall. The sixth reciprocating drive mechanism 801 can be a cylinder, an electric push rod, or other linear reciprocating drive mechanism. The gripper cylinder in the good product handling device 800 is named the second gripper cylinder 802. The fourth mounting bracket 803 is equipped with a guide rail and a slider, and the sixth reciprocating drive mechanism 801 is connected to the slider; the rotating mechanism includes a guide mounting plate 804, a column 805, a connecting rod 806, a swing rod 807, and a swing shaft 808. The guide mounting plate 804 is fixedly connected to the slider, the column 805 is fixed to the fourth mounting bracket 803, one end of the connecting rod 806 is rotatably connected to the column 805, the other end of the connecting rod 806 is rotatably connected to one end of the swing rod 807, the other end of the swing rod 807 is fixedly connected to the swing shaft 808, the swing shaft 808 is mounted on the guide mounting plate 804 through a bearing, and the second gripper cylinder 802 is fixedly connected to the swing shaft 808.

[0096] For example, the lifting device 30 drives the second gripper cylinder 802 to descend, and the second gripper cylinder 802 grips the good component. The lifting device 30 then drives the second gripper cylinder 802 with the good component to rise. The sixth reciprocating drive mechanism 801 retracts, and the guide mounting plate 804 moves together with the slider along the length of the guide rail. The connecting rod 806 and the swing rod 807 are linked to drive the swing shaft 808 to rotate together with the second gripper cylinder 802 by a preset angle. At the same time, the good component also rotates by a preset angle, for example, the preset angle can be, but is not limited to, 90°. When the good component is aligned with the good component holder, the gripper cylinder can release the good component so that the good component falls into the good component holder.

[0097] In this context, a "good component" refers to an assembly where the pencil barrel, locking ring, and clip are assembled together, with the locking ring and clip all in place. The good component holder also has two mounting positions, each accommodating two good components. The good components in the good component holder are then conveyed to the next process for assembling other parts of the mechanical pencil.

[0098] In some embodiments, see Figure 43 and Figure 44 As shown, the automatic pencil assembly equipment also includes a defective product handling device 1000. The defective product handling device 1000 includes a seventh reciprocating drive mechanism 1001 and a third gripper cylinder 1002. The seventh reciprocating drive mechanism 1001 is connected to the lifting device 30 and is connected to the sixth cam 312 via a sixth lifting shaft 306. The seventh reciprocating drive mechanism 1001 can be a cylinder, an electric push rod, or other linear reciprocating drive mechanism. The seventh reciprocating drive mechanism 1001 can drive the third gripper cylinder 1002 to move between the first station and the second station. For example, when the seventh reciprocating drive mechanism 1001 extends, it drives the third gripper cylinder 1002 to move to the first station. At this time, the third gripper cylinder 1002 is aligned with the defective component. The lifting device 30 drives the third gripper cylinder 1002 to descend in order to grip the defective component. When the seventh reciprocating drive mechanism 1001 retracts, it drives the third gripper cylinder 1002 to move to the second station. At this time, the third gripper cylinder 1002 brings the defective component to the top of the recycling hopper and releases the defective component into the recycling hopper.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
