Description

Technical Field

[0001] This utility model relates to the field of assembly machine technology, and in particular to an automatic assembly machine. Background Technology

[0002] As a type of precision cosmetic instrument requiring high-precision control of the release of the eyeliner, the brush head typically consists of a combination of bristles and a handle. Current mainstream manufacturing processes generally employ a step-by-step assembly method: first, the bristle bundles are manually inserted into pre-set holes in the handle; then, the pre-assembled semi-finished brush head is transferred to a punching machine, where double-sided punching causes partial deformation of the handle, thereby achieving mechanical clamping and fixation of the bristles.

[0003] However, in actual production, the separation of the insertion and punching processes means that manual loading and unloading and transfer between workstations are required. This not only makes the work cycle uncontrollable and the production efficiency low, but also makes it difficult to achieve full-process automation and continuous production.

[0004] Therefore, there is an urgent need to provide an automated assembly machine that can achieve automated continuous production of brush heads. Utility Model Content

[0005] One object of this application is to provide an automatic assembly machine that aims to solve at least one of the technical problems existing in the prior art. According to the automatic assembly machine of this application, the automated continuous production of brush heads can be realized.

[0021] The adsorption member adsorbs and lifts the brush bristles under the action of the fourth driving member and moves them above the flipping clamping finger. The brush bristles are then transferred to the flipping clamping finger for clamping. The flipping clamping finger is configured to insert the brush bristles vertically into the brush bristle seat through a flipping action. The transfer table drives the brush bristle seat to move along a circular trajectory to below the brush bristle clamping finger, where the brush bristles are clamped by the brush bristle clamping finger.

[0022] In some embodiments, the brush feeding mechanism further includes a vision detector and a rotating component, the vision detector being disposed on the frame, the rotating component being disposed on the fourth driving component, and the adsorption component being connected to the rotating component;

[0024] In some embodiments, each of the two punching assemblies includes a punching seat, a clamping seat, a punching pin, and a fifth driving member. The punching seat is located on one side of the turntable. The clamping seat is elastically connected to the punching seat. The punching pin passes through the clamping seat and is fixed to the punching seat. The fifth driving member is connected to the punching seat.

[0025] Both of the punching seats move horizontally toward the brush head in the fixture under the action of the fifth driving member, such that the two clamping seats abut against each other, and the two punching needles pass through the corresponding clamping seats and punch holes on the opposite sides of the brush head simultaneously.

[0026] In some embodiments, the discharge mechanism includes a brush head gripper and a sixth drive member, wherein the brush head gripper is located on one side of the turntable and the sixth drive member is connected to the brush head gripper.

[0027] The brush head clamp refers to the brush head that is clamped and lifted under the action of the sixth driving component, and then the brush head is output to the outside.

[0061] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0062] The brush head of eyeliner pencils is generally produced using a step-by-step process where the bristles are manually inserted into the brush handle, and then transferred to an independent punching machine for double-sided stamping and fixing. This method relies on operators to participate in the insertion, loading and unloading processes, which not only makes the work cycle uncontrollable but also results in low production efficiency, severely restricting the improvement of large-scale, continuous and automated production levels.

[0063] Please see Figures 1-3 , Figure 6 and Figure 11In this embodiment of the application, an automatic assembly machine includes a frame 100, a brush rod feeding mechanism 200, a bristle feeding mechanism 300, a punching mechanism 400, and a discharge mechanism 500. The frame 100 is equipped with a turntable 110, on which a plurality of fixtures 120 are arranged circumferentially. The brush rod feeding mechanism 200 is located on the frame 100 and is used to feed brush rods T1 to the fixtures 120. The bristle feeding mechanism 300 is located on the frame 100 and is used to feed bristles T2 to the fixtures 120 and insert the bristles T2 into the brush rods T1 to form brush heads T. The punching mechanism 400 is located on the frame 100 and includes two sets of punching assemblies arranged opposite each other, which are used to simultaneously punch holes on opposite sides of the brush head T. The discharge mechanism 500 is located on the frame 100 and is used to remove the punched brush heads T and output them externally. The brush rod feeding mechanism 200, the bristle feeding mechanism 300, the punching mechanism 400 and the discharge mechanism 500 are arranged sequentially on the frame 100 along the rotation direction of the turntable 110. After the brush rod T1 is placed into the fixture 120 by the brush rod feeding mechanism 200, it is first assembled into a brush head T by the bristle feeding mechanism 300, then punched and fixed by the punching mechanism 400, and finally unloaded and output by the discharge mechanism 500.

[0064] The brush rod feeding mechanism 200 is used to place the brush rod T1 into the unloaded fixture 120, completing its initial positioning. The bristle feeding mechanism 300 is used to insert the bristles T2 onto the brush rod T1 supported by the fixture 120, so that the two together form the brush head T. The punching mechanism 400 is used to simultaneously punch the opposite sides of the brush rod T1 corresponding to the brush head T, so that the brush rod T1 forms through holes to clamp the bristle T2 rod. The discharge mechanism 500 is used to remove the punched and fixed brush head T from the fixture 120 and output it externally.

[0065] Please see Figure 2 After the equipment is started, the turntable 110 rotates continuously on the frame 100, and the multiple jigs 120 arranged around it move forward accordingly. When the jig 120 moves to the brush rod feeding mechanism 200, the brush rod T1 is placed into the jig 120 and precisely positioned. As the turntable 110 continues to rotate, the jig 120 carries the brush rod T1 into the bristle feeding mechanism 300. The bristle feeding mechanism 300 inserts the bristles T2 into the brush rod T1 to form a brush head T. Then the jig 120 is moved to the punching mechanism 400. The two sets of punching components arranged opposite each other move synchronously to punch the brush rod T1 to form through holes to mechanically hold the rod of the bristles T2.

[0066] As the jig 120 rotates continuously with the turntable 110, it can sequentially perform the following processes through the brush rod feeding mechanism 200, the bristle feeding mechanism 300, the punching mechanism 400, and the unloading mechanism 500: placing the brush rod T1, inserting the bristles T2, punching the brush head T, and unloading the brush. Each action is driven by the turntable 110 in a unified rhythm, which effectively reduces the misalignment of process switching time and manual intervention. The whole machine can realize the full cycle of automatic flow of brush head T assembly, and the operation is stable and controllable, making it suitable for large-scale continuous production.

[0067] In some embodiments, the brush rod feeding mechanism 200 includes a brush rod support plate 210, a brush rod clamping finger 220, a first driving member 230, and a second driving member 240. The brush rod support plate 210 is located on one side of the turntable 110 and is used to support the brush rod T1. The brush rod clamping finger 220 is disposed between the brush rod support plate 210 and the turntable 110. The first driving member 230 is connected to the brush rod clamping finger 220, and the second driving member 240 is connected to the first driving member 230. Under the action of the second driving member 240, the brush rod clamping finger 220 clamps and lifts the brush rod T1, and is driven by the first driving member 230 to move above the turntable 110, and then the brush rod T1 is placed into the fixture 120.

[0068] Please see Figures 2-4 When the unloaded fixture 120 rotates with the turntable 110 to the station of the brush rod feeding mechanism 200, the second drive member 240 drives the brush rod clamping finger 220 to descend and clamp the brush rod T1 carried on the brush rod support plate 210. Then, the second drive member 240 drives the brush rod clamping finger 220 to rise, so that the brush rod T1 is disengaged from the brush rod support plate 210. The first drive member 230 drives the brush rod clamping finger 220 to move directly above the fixture 120. The second drive member 240 drives the brush rod clamping finger 220 to descend again and place the brush rod T1 into the fixture 120. Finally, the brush rod clamping finger 220 is released and returns to its original position. This completes the automatic feeding of a single brush rod T1 to the fixture 120.

[0069] The second drive unit 240 can control the brush bar clamping finger 220 to complete the multi-stage lifting and lowering action of lifting and inserting the brush bar T1. The first drive unit 230 coordinates to achieve the precise displacement of the brush bar T1 from the brush bar support plate 210 to the fixture 120. This allows the brush bar T1 to maintain a stable posture throughout the clamping process. The timing of each action is strictly synchronized with the positioning state of the fixture 120. The brush bar T1 can be accurately inserted into the unloaded fixture 120, providing a reliable reference for the subsequent insertion of the bristles T2 and the synchronous punching on both sides, which is conducive to improving the consistency of the brush head T assembly.

[0070] Optional, please refer to Figure 3The first driving component 230 is a rotary cylinder, and the second driving component 240 is a linear cylinder. The linear cylinder is fixed to the frame 100, and its piston rod extends and retracts in the vertical direction. The rotary cylinder is fixed to the end of the piston rod of the linear cylinder, and its output shaft is fixedly connected to a first rotating plate 231. The first rotating plate 231 is strip-shaped, and a brush rod clamping finger 220 is installed at each end. Driven by the rotary cylinder, the two brush rod clamping fingers 220 perform synchronous circular motion around the center of the output shaft of the rotary cylinder. When one brush rod clamping finger 220 places the brush rod T1 into the unloaded fixture 120, the other brush rod clamping finger 220 completes the clamping of the next brush rod T1 at the brush rod support plate 210, thereby realizing the continuous cycle of the brush rod feeding process and improving the feeding cycle utilization rate per unit time.

[0071] In some embodiments, the brush bar feeding mechanism 200 further includes a brush bar vibratory plate 250 and a brush bar vibratory belt 260. The brush bar vibratory plate 250 is disposed on the frame 100, one end of the brush bar vibratory belt 260 is connected to the brush bar vibratory plate 250, and the other end is connected to the brush bar support plate 210. The brush bar support plate 210 has an opening groove C1, and the discharge end of the brush bar vibratory belt 260 is connected to the brush bar support plate 210 for conveying the brush bar T1 into the opening groove C1.

[0072] Please see Figures 3-4 The brush rod T1 is fed directionally via a combination of a brush rod vibratory feeder 250 and a brush rod vibrating belt 260. The brush rod vibratory feeder 250 adjusts the posture of the brush rods T1 and outputs them one by one. The brush rod vibrating belt 260 connects to its output end and conveys the brush rods T1 towards the brush rod support plate 210. The brush rod support plate 210 is mounted on the frame 100 and has an opening slot C1 on one side. The brush rod vibrating belt 260 pushes the first brush rod T1 into the opening slot C1 for temporary storage and limits its movement. After the brush rod clamping fingers 220 complete the clamping and transfer of the brush rod T1, the brush rod vibratory feeder 250 and the brush rod vibrating belt 260 start synchronously, conveying the next brush rod T1 into the opening slot C1, thus achieving continuous brush rod T1 feeding.

[0073] Through the coordinated operation of the brush bar vibratory plate 250 and the brush bar vibratory belt 260, the automatic orientation and sequential supply of brush bars T1 can be realized. This feeding path is linked to the action rhythm of the brush bar clamp finger 220. After the current brush bar T1 is removed, the next brush bar T1 is automatically positioned, thereby reducing the waiting time of the idle station and improving the continuity and stability of the brush bar T1 feeding process, providing a basic guarantee for the high-speed automated assembly of the whole machine.

[0074] Optional, please refer to Figure 3The brush rod support plate 210 is mounted on the frame 100 via a support plate cylinder 211. The support plate cylinder 211 is a linear cylinder, fixed to the frame 100, with its piston rod extending and retracting horizontally. The brush rod support plate 210 is fixedly connected to its piston rod. The support plate cylinder 211 is configured to drive the brush rod support plate 210 to reciprocate in a direction toward or away from the center of the turntable 110. When the brush rod vibrating belt 260 conveys the brush rod T1 to the opening slot C1 of the brush rod support plate 210, the support plate cylinder 211 drives the brush rod support plate 210 to move toward the turntable 110, so that the opening slot C1 is located in the working area of ​​the brush rod clamping finger 220, facilitating stable clamping by the brush rod clamping finger 220. After clamping is completed, the support plate cylinder 211 drives the brush rod support plate 210 to reset, thereby ensuring the safety and reliability of continuous cyclic operation of each mechanism.

[0075] Optional, please refer to Figure 3 A pressing cylinder 270 is also fixed on the frame 100. The piston rod of the pressing cylinder 270 extends and retracts in the vertical direction, which is used to press the brush rod T1 so that the brush rod T1 is stably placed in the fixture 120.

[0076] In some embodiments, the bristle feeding mechanism 300 includes a bristle base 310, bristle clamping fingers 320, and a third drive member 330. The bristle base 310 is located on one side of the turntable 110 and is used to insert bristles T2. The bristle clamping fingers 320 are located between the bristle base 310 and the turntable 110, and the third drive member 330 is connected to the bristle clamping fingers 320. Under the action of the third drive member 330, the bristle clamping fingers 320 clamp and lift the bristles T2 and move them above the turntable 110. Then, the bristles T2 are inserted into the brush rod T1 to form a brush head T.

[0077] Please see Figure 2 and Figure 6 When the fixture 120 carrying the brush rod T1 rotates with the turntable 110 to the position of the brush feeding mechanism 300, the third drive member 330 drives the brush clamp finger 320 to descend, clamping the brush T2 inserted on the brush seat 310. Then, the third drive member 330 drives the brush clamp finger 320 to rise, causing the brush T2 to disengage from the brush seat 310, and drives the brush clamp finger 320 to feed horizontally toward the fixture 120 until it moves directly above the brush rod T1. At this time, the brush clamp finger 320 descends, inserting the brush T2 axially into the preset hole of the brush rod T1. Finally, the brush clamp finger 320 is released and returns to its original position. This completes the automatic feeding and insertion of a single brush T2 onto the brush rod T1. The brush T2 and the brush rod T1 are thus combined to form the brush head T to be punched and fixed.

[0078] The third drive component 330 is used to control the bristle clamping finger 320 to complete the multi-stage lifting and inserting motion of the bristle T2, and at the same time realize the precise displacement of the bristle T2 from the bristle holder 310 to directly above the fixture 120. This allows the bristle T2 to maintain a stable posture throughout the clamping process, and the timing of each action is strictly synchronized with the position of the fixture 120. The bristle T2 can be accurately inserted into the brush bar T1, providing a reliable reference for subsequent synchronous punching and further improving the consistency of the brush head T assembly.

[0079] Optionally, the third driving component 330 is a two-dimensional translation module. The bristle clamp 320 is fixed to the motion platform of the two-dimensional translation module, so that it can move according to a preset trajectory to achieve fixed-point picking and placing of the bristles T2.

[0080] Optional, please refer to Figure 2 A set of symmetrically arranged clamping blocks 130 is provided on the frame 100. The clamping blocks 130 are located above the turntable 110, corresponding to the station of the brush feeding mechanism 300. The set of clamping blocks 130 is preferably driven by pneumatic grippers and is configured to close synchronously when the fixture 120 carrying the brush rod T1 rotates to this station, thereby forming a circumferential limit on the brush rod T1. After the brush bristles T2 are inserted, the pneumatic grippers drive the two clamping blocks 130 to open and reset. The clamping blocks 130 can constrain the brush rod T1 during the insertion of the brush bristles T2, reducing its movement and swaying, and helping to improve the assembly effect of the brush head T.

[0081] In some embodiments, the bristle feeding mechanism 300 further includes a transfer table 340, a flipping gripper 350, a material tray 360, an adsorption member 370, and a fourth drive member 380. The transfer table 340 is disposed on the frame 100, the bristle holder 310 is mounted on the transfer table 340, the bristle gripper 320 is located on one side of the transfer table 340, and the flipping gripper 350 is located on the other side of the transfer table 340. The material tray 360 is disposed on the frame 100 and is used to accommodate multiple bristles T2. The adsorption member 370 is disposed between the material tray 360 and the flipping gripper 350, and the fourth drive member 380 is connected to the adsorption member 370. The adsorption member 370 adsorbs and lifts the brush bristles T2 under the action of the fourth driving member 380, and moves them above the flipping gripper 350. Then, the brush bristles T2 are transferred to the flipping gripper 350 for clamping. The flipping gripper 350 is configured to insert the brush bristles T2 vertically into the brush bristle holder 310 through a flipping action. The transfer table 340 drives the brush bristle holder 310 to move along a circular trajectory to below the brush bristle gripper 320, where the brush bristles T2 are clamped by the brush bristle gripper 320.

[0082] Please see Figures 5-10The frame 100 is equipped with a material tray 360, which contains multiple dispersed brush bristles T2. When the brush bristles T2 are being fed, the fourth drive unit 380 drives the suction unit 370 to descend, suctioning a brush bristle T2 from the material tray 360 and lifting it off the material tray 360. At this time, the brush bristle T2 is in a horizontal position. The suction unit 370 moves the brush bristle T2 to the clamping area of ​​the flipping finger 350, and the flipping finger 350 clamps the brush bristle T2. The suction unit 370 then releases the suction of the brush bristle T2. At this time, the brush bristle T2 still maintains a horizontal position. Then, the flipping finger 350 flips the brush bristle T2 so that it is vertically inserted into the brush bristle holder 310. Then, the transfer table 340 moves, driving the brush bristle holder 310 to move along a circular trajectory to the clamping area of ​​the brush bristle clamp 320. At this time, the brush bristle clamp 320 clamps the brush bristle T2 and moves it further towards the fixture 120 to complete the combination with the brush bar T1.

[0083] The brush bristles T2 are picked up and horizontally transported without contact via the adsorption component 370. Then, the orientation is controllably changed from horizontal to vertical by the flipping gripper 350. The transfer table 340 drives the brush bristle holder 310 to be precisely moved to the insertion station, so that the brush bristles T2 are in the correct spatial orientation and positioning reference before being inserted into the brush bar T1. This multi-stage collaborative process reduces the need for manual intervention, improves the consistency of the insertion direction and the repeatability of the position of the brush bristles T2, and helps to improve the stability of the initial assembly quality of the brush head T and the continuity of the automated operation of the whole machine.

[0084] Optional, please refer to Figure 6 The transfer table 340 includes a motor and a second rotating plate 341. The motor is fixed to the frame 100, and its output shaft is arranged vertically. The second rotating plate 341 has a strip-shaped design, and its center is fixedly connected to the output shaft of the motor. A brush holder 310 is installed at each end. Driven by the motor, the second rotating plate 341 drives the two brush holders 310 to move in a circular motion around the center of the output shaft. When one brush holder 310 moves with the flipped and positioned brush to the working area of ​​the brush clamp finger 320, the other brush holder 310 moves to the working area of ​​the flipping clamp finger 350, ready to receive the next brush T2 conveyed by the adsorption member 370, thereby realizing the continuous cycle of the brush feeding process.

[0085] Optional, please refer to Figures 7-8 The combination of the two components, the flipping gripper 350, includes a gripper and a flipping component. The gripper is a pneumatic gripper, and the flipping component is a rotary cylinder. The rotary cylinder is located on the frame 100, and its output shaft is arranged horizontally. The pneumatic gripper is fixedly connected to the output shaft of the rotary cylinder. When the adsorption component 370 moves the bristles T2 to the pneumatic gripper and releases the adsorption, the rotary cylinder drives the pneumatic gripper to rotate around its output shaft, causing the bristles T2 to flip from a horizontal posture to a vertical posture.

[0086] Optional, please refer to Figures 7-8 In addition to the combination of the two components, a lifting cylinder 351 is also fixed on the frame 100. The lifting cylinder 351 is a linear cylinder, and the flipping gripper 350 is fixedly connected to the cylinder shaft of the lifting cylinder 351. The lifting cylinder 351 can drive the flipping gripper 350 to move up and down as a whole, so that it can be moved to the optimal gripping height of the brush bristles T2 before gripping. This adjustment capability reduces the insufficient gripping space or positioning deviation caused by the fixed installation height, and significantly improves the reachability, position adaptability and operational reliability of the flipping gripper 350 in gripping the brush bristles T2.

[0087] Optional, please refer to Figure 9 A support block 352 is fixed between the two clamping ends of the flip-finger 350. The support block 352 forms a limiting groove C2 for accommodating the bristles T2. The limiting groove C2 has a V-shaped cross section, with the opening facing upward and the depth matching the outer diameter of the bristles T2. When the adsorption member 370 releases its adsorption effect on the bristles T2, the bristles T2 will be placed in the limiting groove C2, with its rod extending outward from the limiting groove C2. After the two clamping ends of the flip-finger 350 have completed clamping the bristle rod, the bristles T2 are inserted into the bristle holder 310 by flipping.

[0088] Optionally, the adsorption element 370 is a vacuum suction head, which achieves the adsorption function of the brush bristles T2 through an external vacuum device (not shown in the figure).

[0089] Optionally, the fourth driving component 380 is a three-dimensional translation module, and the adsorption component 370 is set on the motion platform of the three-dimensional translation module, so that it can move according to a preset trajectory to realize the fixed-point picking and placing of the brush bristles T2.

[0090] Optionally, the frame 100 is also equipped with a brush vibrating plate 361. The discharge port of the brush vibrating plate 361 is located above the material tray 360. The multiple brushes T2 placed on the brush vibrating plate 361 are in a natural stacked state. When the brush vibrating plate 361 is started, the upper layer of brushes T2 can be gradually loosened and fall into the material tray 360, so that the brushes T2 are kept in a relatively dispersed state in the material bin, so as to meet the requirement of the adsorption component 370 to pick up one by one.

[0091] In some embodiments, the bristle feeding mechanism 300 further includes a vision detector 390 and a rotating member 381. The vision detector 390 is disposed on the frame 100, the rotating member 381 is disposed on the fourth drive member 380, and the adsorption member 370 is connected to the rotating member 381. The vision detector 390 is capable of detecting the orientation of the bristles T2 adsorbed by the adsorption member 370, and the rotating member 381 is used to drive the adsorption member 370 to rotate, so as to adjust the orientation of the bristles T2.

[0092] Please see Figure 5 and Figure 10In combination, when the adsorption member 370 adsorbs the brush bristles T2, the vision detector 390 set on the frame 100 can detect the orientation of the brush bristles T2. When the vision detector 390 identifies the orientation deviation of the brush bristles T2, the rotating member 381 drives the adsorption member 370 to rotate, thereby adjusting the orientation of the brush bristles T2 so that it has a reference direction consistent with the clamping direction of the flipping finger 350. Then, the adsorption member 370 moves the brush bristles T2 with the calibrated orientation to above the working area of ​​the flipping finger 350, and the flipping finger 350 clamps the brush bristles T2.

[0093] By setting up a vision detector 390 and a rotating component 381, non-contact fine-tuning of the brush bristles T2 in the adsorption state is achieved. This structure effectively reduces the rotational deviation of the brush bristles T2 caused by feeding errors or adsorption offset, thereby ensuring that the brush bristles T2 can be accurately clamped by the flipping gripper 350 in a standard posture.

[0094] Optionally, the rotating component 381 is a motor, and the adsorption component 370 is installed at the output end of the motor.

[0095] In some embodiments, each of the two punching assemblies includes a punching seat 410, a clamping seat 420, a punching pin 430, and a fifth driving member 440. The punching seat 410 is located on one side of the turntable 110. The clamping seat 420 is elastically connected to the punching seat 410. The punching pin 430 passes through the clamping seat 420 and is fixed to the punching seat 410. The fifth driving member 440 is connected to the punching seat 410. Under the action of the fifth driving member 440, both punching seats 410 move horizontally toward the brush head T in the fixture 120, such that the two clamping seats 420 abut against each other, and the two punching pins 430 pass through their respective clamping seats 420 and punch holes simultaneously on opposite sides of the brush head T.

[0096] Please see Figure 2 and Figures 11-12 When the fixture 120 carrying the brush head T rotates with the turntable 110 to the position of the punching mechanism 400, the fifth drive members 440 of the two sets of punching components drive the corresponding punching seats 410 to move towards each other in the horizontal direction. Since the clamping seat 420 is elastically connected to the punching seat 410, it can move together with the punching seat 410. When the two clamping seats 420 abut against each other to form a circumferential limit on the brush head T, the continued movement of the punching seat 410 will drive the punching pin 430, which is rigidly fixed to it, to pass through the clamping seat 420. The two punching pins 430 can thus punch the opposite sides of the brush rod T1 simultaneously, so that the brush rod T1 forms a through hole to fix the bristle T2 rod.

[0097] By synchronously moving in opposite directions through the two sets of punching components, the two clamping seats 420 can jointly achieve positioning constraint on the brush head T. In this state, the punching needle 430 is rigidly driven through the punching seat 410 to apply symmetrical punching force to the opposite sides of the brush rod T1, forming through holes with consistent position and controllable depth. This dual-sided cooperative punching method improves the problem of uneven force load caused by single-sided punching, which is beneficial to improving the combined stability of the brush head T.

[0098] Optionally, the fifth drive component 440 is a linear cylinder, which is fixed to the frame 100, and its piston rod extends and retracts in the horizontal direction. The punch seat 410 is fixed to the end of the piston rod of the linear cylinder.

[0099] Optional, please refer to Figure 12 Each punching assembly has a punching seat 410 with a horizontally extending guide rod 450. The clamping seat 420 slides into the punching seat 410 via the guide rod 450. A spring (not shown) is also provided between the clamping seat 420 and the punching seat 410, arranged axially along the guide rod 450. One end of the spring abuts against the clamping seat 420, and the other end abuts against the punching seat 410. When the two clamping seats 420 abut against the brush head T, the fifth driving member 440 continues to drive the two punching seats 410 to move in opposite directions. The spring is thus compressed, and the punching needle 430, rigidly fixed to the punching seat 410, protrudes outward from the clamping seat 420 and punches the opposite sides of the brush rod T1.

[0100] Optionally, the frame 100 is fixed with a horizontally arranged guide rail, and the punching seat 410 is slidably mounted on the guide rail and driven to move by the fifth drive member 440.

[0101] In some embodiments, the discharge mechanism 500 includes a brush head gripper 510 and a sixth drive member 520. The brush head gripper 510 is located on one side of the turntable 110, and the sixth drive member 520 is connected to the brush head gripper 510. Under the action of the sixth drive member 520, the brush head gripper 510 grips and lifts the brush head T, and then outputs the brush head T to the outside.

[0102] Please see Figure 2 and Figure 13 When the fixture 120 carrying the brush head T rotates with the turntable 110 to the position of the discharge mechanism 500, the sixth drive member 520 drives the brush head clamping finger 510 to descend, clamping the brush head T that has been punched and fixed in the fixture 120. Then, the sixth drive member 520 drives the brush head clamping finger 510 to rise, so that the brush head T is completely separated from the fixture 120, and drives the brush head clamping finger 510 to move outward in the horizontal direction to the designated unloading position. After reaching the position, the brush head clamping finger 510 descends and releases the brush head T, and then returns to its original position, thus completing a single discharge operation.

[0103] The discharge mechanism 500 enables fully automatic and uninterrupted unloading of the brush head T from the fixture 120 to the external conveying path, replacing the traditional manual handling process and further improving the output efficiency per unit time.

[0104] Optionally, the sixth driving component 520 is a two-dimensional translation module, and the brush head clamp finger 510 is fixed on the motion platform of the two-dimensional translation module, so that it can move according to a preset trajectory to realize the fixed-point picking and placing of the brush head T.

[0105] In addition, the applicant also found that after the brush head is fixed by punching, during the subsequent circulation process, the bristles (the part of the brush T2 used to pick up the eyeliner gel) are prone to local scattering due to inertial swing or slight contact with adjacent parts, which affects the appearance consistency of the brush head.

[0106] In some embodiments, a sleeve mechanism 600 is further included, disposed between the punching mechanism 400 and the discharge mechanism 500. The sleeve mechanism 600 includes a sleeve clamping finger 610, a seventh drive member 620, and an eighth drive member 630. The sleeve clamping finger 610 is located on one side of the turntable 110, the seventh drive member 620 is connected to the sleeve clamping finger 610, and the eighth drive member 630 is connected to the seventh drive member 620. The sleeve clamping finger 610 clamps the lifting sleeve under the action of the eighth drive member 630 and is driven by the seventh drive member 620 to move above the brush head T, whereby the sleeve is then inserted onto the outside of the brush head T.

[0107] Please see Figure 2 and Figures 14-15 When the fixture 120 carrying the punched brush head T rotates with the turntable 110 to the position of the sleeve mechanism 600, the sleeve clamp finger 610 clamps a double-ended through sleeve. The seventh drive member 620 drives the sleeve clamp finger 610 to move directly above the fixture 120, and the eighth drive member 630 drives the sleeve clamp finger 610 to descend, inserting the sleeve vertically along the axial direction onto the outside of the brush head T, so that it envelops the bristles T2. After the sleeve is inserted, the sleeve clamp finger 610 rises back to its original position, and the fixture 120 continues to rotate, transferring the brush head T to the discharge mechanism 500 for unloading.

[0108] By adding a sleeve mechanism 600, a sleeve that serves to restrain and isolate can be inserted on the outside of the brush head T. During the subsequent circulation of the brush head T, the tips of the bristles T2 can be suppressed by the sleeve, thereby effectively reducing the tendency of local scattering caused by inertial swing or contact with adjacent parts, which is conducive to maintaining the integrity of the appearance of the brush head T.

[0109] Optionally, the seventh driving component 620 is a rotary cylinder, and the eighth driving component 630 is a linear cylinder. The linear cylinder is fixed to the frame 100, and its piston rod extends and retracts in the vertical direction. The rotary cylinder is fixed to the end of the piston rod of the linear cylinder, and its output shaft is fixedly connected to a third rotating plate 621. This third rotating plate 621 has a strip-shaped design, with a sleeve clamping finger 610 installed at each end. Driven by the rotary cylinder, the two sleeve clamping fingers 610 perform synchronous circular motion around the center of the rotary cylinder's output shaft. When one sleeve clamping finger 610 inserts the sleeve onto the outside of the brush head T, the other sleeve clamping finger 610 simultaneously completes the clamping of the next sleeve, thus realizing a continuous cycle of sleeve picking and insertion processes.

[0110] In some embodiments, the sleeve mechanism 600 further includes a cutting seat 640, a feeding finger 650, a cutter 660, and a ninth driving member 670. The cutting seat 640 and the feeding finger 650 are sequentially disposed below the sleeve finger 610. The cutter 660 is horizontally movably disposed on the cutting seat 640, and the ninth driving member 670 is connected to the feeding finger 650. Under the action of the ninth driving member 670, the feeding finger 650 causes one end of the flexible tube to pass through the cutting seat 640, the sleeve finger 610 clamps the flexible tube, and the cutter 660 cuts the flexible tube to form a sleeve.

[0111] The sleeve is obtained by cutting a flexible tube; please refer to [link / reference]. Figure 2 and Figures 14-15 The flexible tube is inserted into the tube cutting seat 640 on one side of the frame 100. The flexible tube is inserted into the tube cutting seat 640 from bottom to top and is held by the tube feeding finger 650. When the sleeve clamp finger 610 moves directly above the flexible tube, it can clamp the upper end of the flexible tube. Then the cutter 660 moves back and forth horizontally on the tube cutting seat 640 to cut the flexible tube from the end of the tube, forming an independent sleeve. The sleeve is then transferred by the sleeve clamp finger 610 to the brush head T position for insertion. After the flexible tube is cut, the ninth drive member 670 drives the tube feeding finger 650 to move upward, so that the flexible tube can be inserted again for the next cutting.

[0112] By continuously threading the flexible tube through the tube cutting seat 640, the individual tubes can be cut as needed. This method eliminates intermediate steps such as tube preforming, sorting, and loading. At the same time, it is linked with the turntable 110 to support high-frequency continuous tube supply, improving the integration and operational stability of the assembly process.

[0113] Optional, please refer to Figure 15The ninth driving component 670 is a linear cylinder. The pipe feeding clamp finger 650 is fixed on a slider. The frame 100 is provided with a vertical slide rail. The slider slides on the slide rail and is connected to the linear cylinder, so it can be driven to move up and down by the linear cylinder. After the flexible tube is cut into a sleeve, the pipe feeding clamp finger 650 releases the flexible tube and descends vertically. After re-clamping the flexible tube, it rises vertically, thereby pushing the flexible tube from bottom to top for a preset length, so that a new section of it passes through the pipe cutting seat 640 and is in the position to be cut.

[0114] Optional, please refer to Figure 15 The frame 100 has support fingers 680 spaced apart below the pipe feeding finger 650. The support fingers 680 are fixed to the support base 681. The flexible tube passes through the support base 681 from bottom to top and continues to extend upward to the pipe cutting base 640 after being clamped by the support fingers 680. When the pipe feeding finger 650 releases the flexible tube and descends vertically, the support fingers 680 are in a closed state, applying a clamping force to the flexible tube, making it stably stationed between the support base 681 and the pipe cutting base 640, preventing axial slippage due to its own weight or inertia. After the pipe feeding finger 650 re-clamps the flexible tube, the support fingers 680 open and reset.

[0115] Optional, please refer to Figure 14 A cutting cylinder 661 is fixed on the frame 100. The cutting cylinder 661 is a linear cylinder. The cutting blade 660 is fixedly connected to the piston rod of the cutting cylinder 661, so that it can be driven by the cutting cylinder 661 to move horizontally on the pipe cutting seat 640.

[0116] Optional, please refer to Figure 14 The frame 100 is also fixed with a positioning clamp finger 690. The clamping end of the positioning clamp finger 690 can clamp the brush head T on the fixture 120 to enhance the stability of the brush head T when the sleeve is inserted.

[0117] In some embodiments, a clamping mechanism 700 is further included between the bristle feeding mechanism 300 and the punching mechanism 400. The clamping mechanism 700 includes a clamping member 710 and a tenth driving member 720. The clamping member 710 is spaced above the turntable 110, and the tenth driving member 720 is connected to the clamping member 710. Under the action of the tenth driving member 720, the clamping member 710 moves downward to clamp the bristles T2 into the brush rod T1.

[0118] Please see Figure 2 and Figure 16When the fixture 120 carrying the brush head T rotates with the turntable 110 to the position of the clamping mechanism 700, the tenth drive member 720 drives the clamping member 710 to descend vertically, so that its lower end face abuts against the top of the brush bristles T2. Under the pressure of the clamping member 710, the brush bristles T2 are further embedded into the preset holes of the brush rod T1, forming a temporary clamping state. This clamping state is maintained until the fixture 120 is moved to the position of the punching mechanism 400, which can enhance the stability of the brush head T during the punching process.

[0119] Optionally, the clamping component 710 is a pneumatic gripper finger, whose clamping end is initially closed, used to apply axial pressure to the top of the bristles T2. The tenth driving component 720 is a linear cylinder, fixed to the frame 100 with its piston rod arranged vertically, and the pneumatic gripper finger is fixedly connected to the end of its piston rod. When the fixture 120 rotates to the position of the clamping mechanism 700, the linear cylinder drives the pneumatic gripper finger to descend, so that the bottom surface of its clamping end abuts against and clamps the bristles T2. After clamping, the clamping end of the pneumatic gripper finger opens to release the constraint on the top of the bristles T2, and then returns to its original position under the drive of the linear cylinder. By controlling the opening of the clamping end of the pneumatic gripper finger to release its axial constraint on the bristles T2, the risk of the bristles T2 popping out caused by its direct upward movement can be reduced, which is beneficial to improving the combination stability of the bristles T2 and the brush bar T1.

[0120] In some embodiments, a PLC controller (not shown) is also included, which is electrically connected to the turntable 110, the brush rod feeding mechanism 200, the bristle feeding mechanism 300, the punching mechanism 400, the discharge mechanism 500, the sleeve mechanism 600, and the clamping mechanism 700.

[0121] As the core control unit of the equipment, the PLC controller establishes electrical connections with the relevant circuit components of each mechanism. The PLC controller can acquire equipment operating status data in real time and output control commands to each mechanism according to the preset control program, coordinating and regulating the start-up and closing sequence and operating parameters of each mechanism to ensure the orderly connection of each process and realize the automated and collaborative operation of the equipment.

[0122] As an exemplary implementation, after the equipment is started, the turntable 110 rotates continuously on the frame 100 in indexing increments, and the multiple jigs 120 arranged circumferentially on it advance accordingly. When the jig 120 moves to the brush rod feeding mechanism 200 station, the brush rod T1 is placed into the jig 120 and precisely positioned. As the turntable 110 continues to rotate, the jig 120 carries the brush rod into the bristle feeding mechanism 300 station. The bristle feeding mechanism 300 inserts the bristles T2 into the brush rod T1 to form a brush head T. Then the jig 120 is moved to the punching mechanism 400 station. The two sets of oppositely arranged punching components operate synchronously, punching the two sides of the brush rod T1 respectively to form through holes to mechanically clamp the rod of the bristle T2.
