Technical Field
[0001] This invention belongs to the technical field of automated cosmetic production equipment, specifically an automatic assembly device for assembling brush heads onto brush handles. Background Technology
[0002] In the cosmetics industry, products such as lip gloss and eyeshadow are typically applied using specialized application tools. These tools generally consist of a brush handle and a brush head attached to the end of the handle. The brush handle is usually made of plastic and has an internal socket for attaching the brush head. During production, the brush handle and brush head are often manufactured separately, and after they are formed, they are fixed together using a specific assembly process.
[0003] Currently, a common assembly process is as follows: First, the mounting end of the brush head is manually inserted into the mounting hole at the end of the brush rod to form a pre-assembled body; then, a specific part of the brush rod (i.e., the area corresponding to the mounting end of the brush head) is heated to soften it locally; finally, pressure is applied from the radial outer wall of the brush rod using a push rod to cause radial deformation in the softened brush rod, thereby tightly wrapping and fixing the mounting end of the brush head inside the brush rod.
[0004] However, in actual production, the above assembly processes mostly rely on manual operation. This traditional manual operation method has many drawbacks: First, the control of heating temperature depends entirely on the operator's experience, making it difficult to guarantee accuracy and consistency. If the heating temperature is insufficient and the brush rod is not sufficiently softened, the brush rod is prone to cracking or even breaking due to stress concentration during subsequent radial extrusion, resulting in product scrap. If the heating temperature is too high, it will cause the brush rod or brush head to partially melt or scorch, affecting not only the product's appearance but also its performance. Second, manual operation is inefficient and cannot meet the needs of large-scale industrial production. Third, due to differences in the operator's skill level and operating conditions, the final product's installation quality and consistency vary, making it difficult to guarantee a high yield rate. Summary of the Invention
[0005] This invention addresses the shortcomings of existing technologies by providing an automatic brush head assembly device for brush rods. This automatic brush head assembly device can effectively control the heating temperature, avoid excessively high or low heating temperatures, effectively improve assembly efficiency, ensure installation consistency, and achieve automated assembly.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic brush head assembly device for a brush rod, comprising a fixed platform and a rotating platform. Positioning seats are evenly arranged around the rotation center on the rotating platform. A brush rod feeding mechanism, a brush head feeding mechanism, a brush rod heating mechanism, a brush rod marking mechanism, and a discharging mechanism are sequentially arranged around the rotation center on the fixed platform. A visual grasping mechanism and a buffer conveying platform are each provided on the front side of the brush rod feeding mechanism and the brush head feeding mechanism. The brush rod feeding mechanism and the brush head feeding mechanism respectively grasp the material corresponding to the buffer conveying platform to place it... The visual grasping mechanism includes a robotic arm, a feeding tray connected to a vibration mechanism, and a camera aligned with the feeding tray. The buffer conveying platform includes two parallel slides with conveyor belts running in opposite directions at the bottom of the two slides. Several sliders with positioning seats are slidably arranged in the slides. The two ends of the slides are connected and equipped with a first cylinder that pushes the sliders to the other slide. The outlet side of the conveyor belt is the slider accumulation end. The two slider accumulation ends are respectively the loading position of the robotic arm and the picking position of the brush rod loading mechanism or the brush head loading mechanism. During processing, this automatic brush head assembly equipment uses the intermittent rotation of a rotating platform to sequentially transfer the positioning seat to various positions for assembly or processing. The brush rod is loaded when it is in the brush rod feeding mechanism, the brush head is loaded when it is in the brush head feeding mechanism, the brush rod is heated when it is in the brush rod heating mechanism, the brush head is dotted when it is in the brush rod dotting mechanism, and the brush rod is unloaded when it is in the unloading mechanism. Due to the vision-based grasping mechanism, the vibration of the vibration mechanism changes the placement of the material, and the camera determines the material suitable for grasping. Then, the robotic arm grasps the material. During this process, the grasping speed may be inconsistent, potentially leading to prolonged pauses. To stabilize the production cycle, a buffer conveying platform is added. This platform accumulates the material grasped by the robotic arm at the picking position for the brush rod feeding mechanism or the brush head feeding mechanism to retrieve, thus fixing the production cycle. Because the production cycle is fixed, the brush rod heating mechanism can be set to a fixed temperature to heat the brush rod, avoiding excessively high or low temperatures, effectively improving assembly efficiency, ensuring installation consistency, and achieving automated assembly.
[0007] In the above technical solution, preferably, the robotic arm is a four-axis robotic arm, which is equipped with a first gripper that can be raised, lowered, and rotated. The buffer conveying platform is equipped with a flipping fixture for flipping incoming materials. The flipping fixture includes a first vertical slide rail, on which a first sliding seat driven by a second cylinder is slidably mounted. A rotating shaft is transversely mounted on the first sliding seat. A first pneumatic gripper is mounted at one end of the rotating shaft, and a radial extension is mounted at the other end of the rotating shaft. A first guide block is mounted on the radial extension. The flipping fixture also includes an arc-shaped guide groove. The first guide block slides within the arc-shaped guide groove. When the first sliding seat driven by the second cylinder slides, the guide block drives the rotating shaft to rotate 90 degrees under the guidance of the arc-shaped guide groove, so that the first pneumatic gripper switches between a horizontal receiving position and a vertical discharging position. Using a four-axis robot with a flipping fixture can significantly reduce costs compared to a six-axis robot. The four-axis robot uses lifting and rotation to grab the material with the first gripper, then delivers the material to the receiving position of the first pneumatic gripper. Then, the second cylinder drives the first sliding seat to descend, flipping the first pneumatic gripper to the unloading position. The first pneumatic gripper releases the material and places it into the positioning seat on the slider.
[0008] In the above technical solution, preferably, both the brush rod feeding mechanism and the brush head feeding mechanism include a first support frame. The top of the first support frame is provided with a second guide groove. The second guide groove includes a horizontal groove in the middle and vertical grooves connected to the bottom of both sides of the horizontal groove. A first transverse slide rail is provided on the first support frame. A second sliding seat is provided on the first transverse slide rail. A vertical slide groove is provided on the second sliding seat. A second vertical slide rail is slidably disposed within the vertical slide groove. A second guide block is provided at the top of the second vertical slide rail and slides within the second guide groove. A second pneumatic gripper is provided at the bottom of the second vertical slide rail. The first support frame also includes a swing arm driven by a rotary cylinder that rotates around a rotation center within the second guide groove. A fork is provided at the outer end of the swing arm, and the second guide block is located within the fork. This structure allows the rotary cylinder to reciprocate by rotating the swing arm, causing the fork to drive the second guide block to move along the second guide groove, thus realizing the operation of the second pneumatic gripper grabbing material and then rising, translating, lowering to release the material, and resetting.
[0009] In the above technical solution, preferably, the first support frame is provided with an upright plate, and the upright plate is provided with a first guide plate and a second guide plate. Both the first and second guide plates include a vertical groove at one end and a partial horizontal groove. The first and second guide plates are staggered and joined at the horizontal groove position to form the second guide groove. The distance between the first and second guide plates is adjustable to change the lateral stroke of the second gripper. This structure allows for adjustment of the distance between the first and second guide plates as needed, i.e., adjustment of the length of the horizontal groove, thereby changing the horizontal stroke of the second gripper and adapting to different gripping strokes.
[0010] In the above technical solution, preferably, the upright plate is provided with a transverse groove, and the first guide plate and the second guide plate are disposed within the transverse groove. This structure ensures that adjusting the distance between the first guide plate and the second guide plate does not affect the levelness of the horizontal groove.
[0011] In the above technical solution, preferably, the brush rod heating mechanism includes a second bracket, on which a heating element driven by a first lifting cylinder is mounted. A positioning detection device is installed at the material handling position of the buffer conveying platform. Position detection devices are also installed at the rear of both the brush rod feeding mechanism and the brush head feeding mechanism. When any of the positioning detection devices detects a lack of material, the heating element driven by the first lifting cylinder rises. This structure, through the cooperation of the positioning detection device and the first lifting cylinder, prevents the brush rod lacking material from being heated, or prevents the brush rod already in the heating position from being overheated when there is a lack of material at the rear.
[0012] In the above technical solution, preferably, the brush rod dotting mechanism includes a support base, on which a third vertical slide rail is provided. Two second transverse slide rails are provided on both sides below the third vertical slide rail. A third sliding seat driven by a second lifting cylinder is slidably mounted on the third vertical slide rail. A fourth sliding seat is slidably mounted on each of the two second transverse slide rails. The third and fourth sliding seats are connected by a connecting rod hinged at both ends. A top rod is provided on the opposing surfaces of the two fourth sliding seats to press the brush rod and induce plastic deformation. A stop plate is provided on the support base to hold the brush head in place. This structure achieves the dotting operation of the brush rod by raising and lowering the second lifting cylinder. When the brush rod with the brush head is in position, the second lifting cylinder drives the third sliding seat to rise. At this time, the fourth sliding seats on both sides move towards each other under the action of the connecting rod. The top rod then presses inward on the outer wall of the brush rod to create a plastic deformation indentation to position the brush head. The stop plate holds the brush head in place to prevent it from popping out when the top rod presses.
[0013] In the above technical solution, preferably, each of the two fourth sliding seats has a clamping member on its opposing surface, and the end of the clamping member has a clamping opening for holding the brush rod when they are joined. This structure ensures that the clamping opening can hold the brush rod when the two fourth sliding seats move towards each other, preventing the brush rod from shifting and ensuring accurate marking. The clamping member can be designed with different sized clamping openings according to different brush rod models.
[0014] In the above technical solution, preferably, the fourth sliding seat is provided with a top rod positioning groove, and the top rod is replaceably disposed in the top rod positioning groove. A positioning block for positioning the top rod is provided on the side of the top rod positioning groove. This structure allows for the replacement of top rods of different lengths or with different top thicknesses according to different brush rod models, thereby adapting to different models of brush rods for dotting processing.
[0015] In the above technical solution, preferably, the brush rod marking mechanism includes a third support frame, on which a fourth vertical slide rail is provided. The support seat is slidably mounted on the fourth vertical slide rail. An adjusting screw is vertically rotatably mounted on the third support frame, and the adjusting screw is threadedly engaged with the support seat. This structure allows the height of the support seat to be adjusted by rotating the adjusting screw, thereby adapting to the processing of brush rods with different marking positions.
[0016] Compared with existing technologies, this invention has the following advantages: During processing, this automatic brush head assembly equipment uses the intermittent rotation of a rotating platform to sequentially transfer the positioning seat to various positions for assembly or processing. The brush rod is loaded when it is in the brush rod feeding mechanism, the brush head is loaded when it is in the brush head feeding mechanism, the brush rod is heated when it is in the brush rod heating mechanism, the brush head is dotted when it is in the brush rod dotting mechanism, and the brush rod is unloaded when it is in the unloading mechanism. Due to the visual grasping mechanism, the vibration of the vibration mechanism changes the placement of the material, and the camera captures the image. The camera determines the material suitable for gripping, and then the robotic arm grips it. During this process, the gripping speed may be inconsistent, and there may be long periods of stagnation. To fix the production rhythm, a buffer conveying platform is added. The buffer conveying platform can accumulate the material gripped by the robotic arm at the material picking position for the brush rod feeding mechanism or the brush head feeding mechanism to pick up the material, thereby fixing the production rhythm. Since the production rhythm is fixed, the brush rod heating mechanism can set a fixed temperature to heat the brush rod, avoiding excessively high or low heating temperatures, effectively improving assembly efficiency, ensuring installation consistency, and realizing automated assembly.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1 to 12An automatic brush head assembly device for a brush rod includes a fixed platform 1 and a rotating platform 2. Positioning seats 3 are evenly arranged around the rotation center on the rotating platform 2. A brush rod feeding mechanism 4, a brush head feeding mechanism 4a, a brush rod heating mechanism 5, a brush rod dotting mechanism 6, and a discharging mechanism 7 are sequentially arranged around the rotation center on the fixed platform 1. A vision gripping mechanism 8 and a buffer conveying platform 9 are respectively arranged in front of the brush rod feeding mechanism 4 and the brush head feeding mechanism 4a. The brush rod feeding mechanism 4 and the brush head feeding mechanism 4a respectively grip the material corresponding to the buffer conveying platform 9 and place it into the positioning seats 3 on the rotating platform 2. The vision gripping mechanism... 8 includes a robotic arm 10, a feeding tray 12 connected to a vibration mechanism 11, and a camera 13 aligned with the feeding tray 12; the buffer conveying platform 9 includes two parallel slides 14, with a conveyor belt 15 running in opposite directions at the bottom of the two slides 14, and several sliders 16 with positioning seats 3 slidingly arranged in the slides 14. The two ends of the slides 14 are connected and equipped with a first cylinder 17 that pushes the sliders 16 to the other slide 14. The outlet side of the conveyor belt 15 is the accumulation end of the sliders 16, and the two accumulation ends of the sliders 16 are respectively the feeding position of the robotic arm 10 and the picking position of the brush rod feeding mechanism 4 or the brush head feeding mechanism 4a. During processing, this automatic brush head assembly equipment uses the intermittent rotation of the rotating platform 2 to sequentially transfer the positioning seat 3 to various positions for assembly or processing. The brush rod is loaded at the brush rod feeding mechanism 4, the brush head is loaded at the brush head feeding mechanism 4a, the brush rod is heated at the brush rod heating mechanism 5, the brush head is marked at the brush rod marking mechanism 6, and the brush rod is unloaded at the unloading mechanism 7. The visual gripping mechanism 8, along with the vibration of the vibration mechanism 11, changes the placement of the material, and the camera 13 determines whether it is suitable for gripping based on the image captured. The material is then gripped by the robotic arm 10. During this process, the gripping speed is inconsistent and there may be long periods of stagnation. To fix the production cycle, a buffer conveying platform 9 is added. The buffer conveying platform 9 can pile the material gripped by the robotic arm 10 at the material picking position for the brush rod feeding mechanism 4 or the brush head feeding mechanism 4a to pick up the material, thereby fixing the production cycle. Since the production cycle is fixed, the brush rod heating mechanism 5 can set a fixed temperature to heat the brush rod, avoiding excessively high or low heating temperatures, effectively improving assembly efficiency, ensuring installation consistency, and realizing automated assembly.
[0030] In this embodiment, the brush rod feeding mechanism 4 and the brush head feeding mechanism 4a have the same structure, and their front vision gripping mechanism 8 and buffer conveying platform 9 are also the same.
[0031] In this embodiment, the rotating platform 2 has mounting holes for inserting into the positioning seat 3, so that the positioning seat 3 can be replaced according to the model of the brush rod. The slider 16 is also provided with mounting holes for inserting into the positioning seat 3, so that the positioning seat 3 can be replaced according to the model of the brush rod.
[0032] In this embodiment, the robotic arm 10 is a four-axis robotic arm 10. The four-axis robotic arm 10 is equipped with a first gripper 18 that can be raised, lowered, and rotated. The buffer conveying platform 9 is equipped with a flipping fixture 19 for flipping incoming materials. The flipping fixture 19 includes a first vertical slide rail 20. A first sliding seat 22 driven by a second cylinder 21 is slidably arranged on the first vertical slide rail 20. A rotating shaft 23 is transversely arranged on the first sliding seat 22. A first pneumatic gripper 24 is arranged at one end of the rotating shaft 23. A radial extension 25 is arranged at the other end of the rotating shaft 23. A first guide block 26 is arranged in the radial extension 25. The flipping fixture 19 also includes an arc-shaped guide groove 27. The first guide block 26 slides in the arc-shaped guide groove 27. When the first sliding seat 22 driven by the second cylinder 21 slides, the guide block drives the rotating shaft 23 to rotate 90 degrees under the guidance of the arc-shaped guide groove 27, so that the first pneumatic gripper 24 switches between a horizontal receiving position and a vertical discharging position. Using a four-axis robot 10 in conjunction with a flipping fixture 19 can significantly reduce costs compared to a six-axis robot 10. The four-axis robot 10 uses lifting and rotation to grab the material with the first gripper 18, and then delivers the material to the receiving position of the first pneumatic gripper 24. Then, the second cylinder 21 drives the first sliding seat 22 to descend, flipping the first pneumatic gripper 24 to the material release position. The first pneumatic gripper 24 releases and places the material into the positioning seat 3 on the slider 16.
[0033] In this embodiment, both the brush rod feeding mechanism 4 and the brush head feeding mechanism 4a include a first support frame 28. The top of the first support frame 28 is provided with a second guide groove 29. The second guide groove 29 includes a horizontal groove 30 in the middle and vertical grooves 31 connected to the bottom of both sides of the horizontal groove 30. The first support frame 28 is provided with a first transverse slide rail 32. The first transverse slide rail 32 is provided with a second sliding seat 33. The second sliding seat 33 is provided with a vertical slide groove 34. The second vertical slide rail 35 is slidably arranged in the vertical slide groove 34. The top of the second vertical slide rail 35 is provided with a second guide block 36 that slides in the second guide groove 29. The bottom of the second vertical slide rail 35 is provided with a second air gripper 37. The first support frame 28 is also provided with a swing arm 39 driven by a rotary cylinder 38 that rotates around the rotation center in the second guide groove 29. The outer end of the swing arm 39 is provided with a fork 40. The second guide block 36 is located in the fork 40. This structure enables the rotary cylinder 38 to reciprocate the rotation of the swing arm 39, which in turn causes the fork 40 to drive the second guide block 36 to move along the second guide groove 29, thereby realizing the operation of the second pneumatic gripper 37 lifting, translating, lowering to release the material, and resetting after grabbing the material.
[0034] In this embodiment, a vertical plate 41 is provided on the first support frame 28, and a first guide plate 42 and a second guide plate 43 are provided on the vertical plate 41. Both the first guide plate 42 and the second guide plate 43 include a vertical groove 31 at one end and a partial horizontal groove 30. The first guide plate 42 and the second guide plate 43 are misaligned and connected at the position of the horizontal groove 30 to form a second guide groove 29. The distance between the first guide plate 42 and the second guide plate 43 is adjustable to change the lateral stroke of the second pneumatic gripper 37. This structure allows for adjustment of the distance between the first guide plate 42 and the second guide plate 43 as needed, i.e., adjustment of the length of the horizontal groove 30, thereby changing the horizontal stroke of the second pneumatic gripper 37 to adapt to different gripping strokes.
[0035] In this embodiment, a transverse groove 44 is provided on the upright plate 41, and the first guide plate 42 and the second guide plate 43 are disposed within the transverse groove 44. This structure ensures that adjusting the distance between the first guide plate 42 and the second guide plate 43 will not affect the levelness of the horizontal groove 30.
[0036] In this embodiment, the brush rod heating mechanism 5 includes a second bracket 45, on which a heating element 47 driven by a first lifting cylinder 46 is mounted. A positioning detection device 48 is installed at the material handling position of the buffer conveying platform 9. Position detection devices 48 are also installed at the rear of both the brush rod feeding mechanism 4 and the brush head feeding mechanism 4a. When any positioning detection device 48 detects a lack of material, the heating element 47 driven by the first lifting cylinder 46 rises. This structure, through the cooperation of the positioning detection device 48 and the first lifting cylinder 46, prevents the brush rod lacking material from being heated, or prevents the brush rod already in the heating position from being overheated when there is a lack of material at the rear. The positioning detection device 48 can be an infrared sensor or a distance sensor commonly used in automated equipment. In this embodiment, the bottom of the heating element 47 has a notch for the brush rod to pass through, and the heating element 47 is heated by electric heating.
[0037] In this embodiment, the brush rod dotting mechanism 6 includes a support base 49, on which a third vertical slide rail 50 is provided. Two second horizontal slide rails 51 are provided on both sides below the third vertical slide rail 50. A third sliding seat 53 driven by a second lifting cylinder 52 is slidably provided on the third vertical slide rail 50. A fourth sliding seat 54 is slidably provided on each of the two second horizontal slide rails 51. The third sliding seat 53 and the fourth sliding seat 54 are connected by a connecting rod 55 with hinged ends. A top rod 56 is provided on the opposite surface of the two fourth sliding seats 54 for pressing the brush rod to produce plastic deformation. An abutment plate 57 is provided on the support base 49 for pressing the brush head. This structure utilizes the lifting and lowering of the second lifting cylinder 52 to achieve the dotting operation of the brush rod. When the brush rod with the brush head is in position, the second lifting cylinder 52 drives the third sliding seat 53 to rise. At this time, the fourth sliding seats 54 on both sides move towards each other under the action of the connecting rod 55. The top rod 56 presses inward on the outer wall of the brush rod to create a plastic deformation indentation to position the brush head. The abutment plate 57 is used to hold the brush head and prevent it from popping out when the top rod 56 presses it. The abutment plate 57 is fixed to the support base 49 with screws. The whole is a bent block with the bottom of the bent block fixed flat on the support base 49. The bottom is used to hold the brush head. The side of the bent block is provided with a vertical waist hole. The screw passes through the waist hole to fix it to the support base 49. The height of the abutment plate 57 can be adjusted by adjusting the fixing position in the waist hole to adapt to the processing of different models of brush rods.
[0038] In this embodiment, clamping members 58 are provided on the opposing surfaces of the two fourth sliding seats 54, and the ends of the clamping members 58 have clamping openings 59 for holding the brush rod when they are assembled. This structure ensures that the clamping openings 59 can hold the brush rod when the two fourth sliding seats 54 move towards each other, preventing the brush rod from shifting and ensuring accurate marking. The clamping members 58 can be designed with clamping openings 59 of different sizes according to different brush rod models.
[0039] In this embodiment, a push rod positioning groove 60 is provided on the fourth sliding seat 54, and a push rod 56 is replaceably provided in the push rod positioning groove 60. A positioning block 61 for positioning the push rod 56 is provided on the side of the push rod positioning groove 60. With this structure, push rods 56 of different lengths or different top thicknesses can be replaced according to different brush rod models, thereby adapting to different models of brush rods for dotting processing.
[0040] In this embodiment, the brush rod marking mechanism 6 includes a third support frame 62, on which a fourth vertical slide rail 63 is provided. A support base 49 is slidably disposed on the fourth vertical slide rail 63. An adjusting screw 64 is vertically rotatably disposed on the third support frame 62, and the adjusting screw 64 is threadedly engaged with the support base 49. This structure allows the height of the support base 49 to be adjusted by rotating the adjusting screw 64, thereby adapting to the processing of brush rods with different marking positions.
[0041] In this embodiment, two unloading mechanisms 7 are provided. The front unloading mechanism 7 is used to unload fully assembled materials, while the rear unloading mechanism 7 unloads incompletely assembled materials, clearing any remaining material from the positioning seat 3 to avoid affecting subsequent assembly processes. This unloading structure is a commonly used structure in automated equipment; see [link to relevant documentation]. Figure 12 The specific structure will not be described in detail here.
[0042] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
