Description

Technical Field

[0002] Many products consist of multiple parts, such as brushes used in the medical field. A typical structure of such brushes includes a handle, a sleeve, and a brush head. The brush head is assembled and fixed to the head of the handle, and the sleeve is fitted onto the handle, allowing them to rotate relative to each other. Traditionally, these multi-part products with handles (barrels) are assembled manually, which is not only inefficient but also requires a large workforce and incurs high labor costs.

Detailed Implementation

[0031] This embodiment uses the assembly of a medical testing brush as an example for illustration, referring to... Figures 1-14 The medical testing brush includes three parts: a brush handle 91, a sleeve 92, and a brush head 93. The brush head 93 is inserted and fixed to the head of the brush handle 91. The sleeve 92 is fitted onto the front part of the brush handle 91. When the sleeve 92 is pinched by the fingers, the brush head can be rotated by rotating the brush handle 91. The automated assembly machine includes a body and a control system (neither shown). A feeding mechanism, a unloading mechanism, and an assembly mechanism 8 are installed on the worktable 1 of the machine body. The feeding mechanism and assembly mechanism 8 are uniformly controlled by the control system. The feeding mechanism includes three sets (the number can be adjusted according to the number of product parts, such as two, four, or more sets), each set catering to the feeding process of a specific material workpiece. A material traveling mechanism 5 is also installed on the worktable 1, extending along the direction of the process flow. The feeding mechanism and assembly mechanism 8 both face the material traveling mechanism 5. The material traveling mechanism 5 includes at least two carrier members, each with a grooved structure for the brush handle 91. At least one carrier member is a movable carrier member, connected to a lifting drive device and a traveling drive device. The traveling drive device drives the raised carrier member to carry the brush handle 91 forward, thus achieving the travel of the brush handle 91.

[0032] The supporting component is a rack, and the groove structure is a toothed groove; the rack includes two fixed racks 51 and two movable racks 52, and the movable supporting component is the movable rack 52; the two fixed racks 51 and the two movable racks 52 are parallel to each other, and the two movable racks 52 are arranged between the two fixed racks 51; a baffle 53 is provided on the outside of the two fixed racks 51, and the top of the baffle 53 is higher than the top of each rack, forming a channel for the brush handle 91 to travel through the two baffles 53; the two movable racks 52 are higher than the two fixed racks 51 when raised, and lower than the two fixed racks 51 when lowered.

[0033] The bottoms of the two movable racks 52 are connected to each other to form an integral structure, which can be raised and lowered together. A lifting cylinder 54 is connected to the bottom of the movable racks 52 as a lifting drive device. The lifting cylinder 54 is mounted on a cylinder mounting bracket 55, which is movably mounted on a track 512. The track 512 is mounted on the bottom surface of the worktable 1 in a position parallel to the fixed racks 51. The traveling drive device adopts a traveling cylinder 56. The cylinder mounting bracket 55 is connected to the cylinder rod of the traveling cylinder 56 through a fisheye joint 57, so that the cylinder mounting bracket 55 can perform traveling and lifting movements simultaneously. Limiters 58 are respectively set at the head and tail ends of the cylinder mounting bracket 55 to separate the space range for the cylinder mounting bracket 55 to move back and forth, preventing it from moving excessively.

[0034] After the lifting cylinder 54 lifts the movable rack 52, the traveling cylinder 56 activates, pushing the cylinder fixing bracket 55 forward once. This causes the brush handle 91 on the movable rack 52 to move forward one tooth groove distance and fall into the previous tooth groove of the fixed rack 51. Then, the lifting cylinder 54 lowers to its original position, the movable rack 52 lowers accordingly, and the traveling cylinder 56 retracts to its original position, returning the movable rack 52 to its original position. This action is repeated, thus continuously feeding the brush handle 91 forward.

[0035] A limiting bracket 510 is installed on the workbench 1. The limiting bracket 510 extends across the baffle 53 and above the fixed rack 51 and the movable rack 52. A limiting rod 511 is installed on the limiting bracket 510. The position of the limiting rod 511 is slightly higher than the position of the movable rack 52 when it is raised to its highest position, so as to limit the brush handle 91 and prevent it from jumping out of the tooth groove of the fixed rack 51 and causing mess.

[0036] The feeding mechanism includes a first feeding mechanism 2, which includes two hoppers 21, each containing a roller 22 connected to a roller motor 23. Several grooves 24 for placing brush handles 91 (or other rod-shaped workpieces) are provided on the circumference of the rollers 22. A discharge port 25 is provided at the bottom of each hopper 21, suspended above the fixed rack 51 and the movable rack 52. When the roller 21 rotates until any of its grooves 24 aligns with the discharge port 25, the brush handles 91 in the grooves 24 fall into the grooves of the fixed rack 51 under their own weight. One of the two hoppers 21 feeds to the odd-numbered grooves of the fixed rack 51, while the other hopper 21 feeds to the even-numbered grooves. Simultaneous feeding by both hoppers improves feeding efficiency.

[0037] The feeding mechanism also includes a second feeding mechanism 3 for conveying the sleeve 92, which is located next to the material traveling mechanism 5. The second feeding mechanism 3 includes a rotating frame 31, which is connected to a rotating cylinder 32 to achieve horizontal rotation, the purpose of which is to pick up the sleeve 92 from the picking position and rotate it to the insertion position on the other side. The two ends of the rotating frame 31 are respectively connected to gripper cylinders 34, and the gripper cylinders 34 are connected to grippers 33. A transfer material seat 35 and an insertion material seat 37 are respectively provided below the two ends of the rotating frame 31. The transfer material seat 35 is connected to a first vibrator. 411 has a first vibrating plate 41, and the insert material seat 37 is connected to the side of the material traveling mechanism 5; the rotary cylinder 32 is installed on a lifting cylinder 36 so that the rotating frame 31 and the gripper 33 can be lifted and lowered together, first raised to avoid the position and then rotated, and then lowered; an insert cylinder 38 is provided behind the insert material seat 37, the insert cylinder 38 is connected to an insert push plate 39, the insert push plate 39 is connected to two insert push rods 310, the insert push rods 310 are opposite to the insert material seat 37 to form an insertion structure that pushes the sleeve 92 toward the brush handle 91 placed on the fixed rack 51.

[0038] A clamping cylinder 312 is installed next to the insert base 37. The clamping cylinder 312 is connected to two clamping brackets 311. The clamping cylinder 312 controls the two clamping brackets 311 to close together to clamp the brush handle 91.

[0039] After the brush handle 91 falls into the insert base 37, the insert cylinder 38 is activated, pushing the insert push plate 39 and the insert push rod 310 together to move towards the material conveying mechanism 5. The two brush handles 91 on the fixed rack 51 opposite to the insert push rod 310 are clamped by the clamping bracket 311. As the insert push rod 310 pushes the sleeve 92 forward, it will eventually be fitted onto the brush handle 91.

[0040] The feeding mechanism also includes a third feeding mechanism 6 for conveying brush heads 93. The third feeding mechanism 6 is located next to the end of the material traveling mechanism 5 (i.e., near the end of the process flow). An inclined downward discharge channel 10 is provided at the end of the material traveling mechanism 5 as a discharge mechanism, and a receiving box can be placed below to receive finished products. The third feeding mechanism 6 includes a mounting base 61. A material picking lifting cylinder 58 is installed on the bottom surface of the mounting base 61 through a material picking linear module 69. The material picking lifting cylinder 68 is connected to a hanger 62. A material picking cylinder 63 and a material transfer cylinder 65 are respectively installed at the front and rear positions of the bottom of the hanger 62. The material transfer cylinder 65 is located near the... The material moving mechanism 5 has a material picking cylinder 63 located away from it. The material picking cylinder 63 is connected to a material picking claw 64, and the material transferring cylinder 65 is connected to a material transferring claw 66. A second vertical vibrator 44 is provided at the material picking starting position, and the second vertical vibrator 44 is connected to a second vibrating plate 42. A material dispensing seat 611 is provided near the material moving mechanism 5, and the material dispensing seat 611 is connected to a material seat cylinder 612 to achieve lifting and lowering. A transfer seat 610 is provided between the material picking starting position and the material dispensing seat 611, and the distance between the transfer seat 610 and the material picking starting position and the material dispensing seat 611 is the same as the distance between the material picking claw 64 and the material transferring claw 66.

[0041] The linear module 69 drives the lifting cylinder 68, causing the picking claw 64 and the transferring claw 66 to move and align with the starting position of picking and the transfer seat 610, respectively. Then, the lifting cylinder 68 drives the hanger 62 to descend until the picking claw 64 and the transferring claw 66 are close to the brush head 93. The picking cylinder 63 and the transferring cylinder 65 then actuate, with the picking claw 64 grabbing a brush head 93 placed on the second vibrator 44, while the transferring claw 66 grabs the brush head 93 from the transfer seat 610. The lifting cylinder 68 moves upward and forward with the cooperation of the linear module 69 until the transferring claw 66 aligns with the dispensing seat 611 and the picking claw 64 aligns with the transfer seat 610. Under the control of their respective cylinders, the transferring claw 66 places the brush head 93 it has grabbed onto the dispensing seat 611, and the picking claw 64 places the brush head 93 it has grabbed onto the transfer seat 610.

[0042] The feeding surface of the second vibrator 44 is tilted backward and downward, and the brush head 93 is placed on it in an inclined position for stable gripping. A material-picking push cylinder 67 is installed on the middle bottom surface of the hanger 62. The material-picking push cylinder 67 is connected to the material-picking cylinder 63 through a joint shaft to form a structure that can push the material-picking cylinder 63 to rotate to an inclined position to adapt to the posture of the brush head 93. Of course, the material-picking cylinder 63 can also be pushed to a vertical position.

[0043] The assembly mechanism 8 is located on the opposite side of the material conveying mechanism 5 and the feeding seat 611. A clearance opening 59 is provided on the baffle 53 of the material conveying mechanism 5, opposite to the assembly mechanism 8. The assembly mechanism 8 includes a rotary motor 82 and a push motor 81. The rotary motor 82 is mounted on the push motor 81, which is mounted on the worktable 1. A rotating head 83 is mounted at the front end of the rotary motor 82, and a connector 84 for inserting the brush handle 91 is mounted at the front end of the rotating head 83. The push motor 81 drives the rotary motor 82 and the rotating head 83 together towards the brush handle 91. When the tail end of the brush handle 91 is inserted into the connector 84, the rotary motor 82 starts, rotating and pushing forward simultaneously, ultimately inserting the front end of the brush handle 91 into the brush head 93, thus completing the assembly.

[0044] A pressing mechanism 7 is provided between the third feeding mechanism 6 and the assembly mechanism 8. The pressing mechanism 7 includes a fixed base 71 and a pressing frame 72. A pressing cylinder 73 is installed on the fixed base 71. The pressing frame 72 is connected to the pressing cylinder 73 and suspended above the material traveling mechanism 5.

A pressing head cylinder 74 is also installed on the fixed base 71. The pressing head cylinder 74 is connected to the pressing head arm 75. The pressing head arm 75 is suspended above the discharging seat 611. The pressing head cylinder 74 drives the pressing head arm 75 to descend to press down the brush head 93 placed on the discharging seat 611 so that the brush head 93 can remain stable when the brush handle 91 is inserted.

[0045] The brush handle 91 is placed in the hopper 21 according to a set direction by manual labor or a robotic arm. The sleeve 92 and brush head 93 are placed in the first vibrating plate 41 and the second vibrating plate 42 respectively for vibration feeding. When the brush handle 91 is conveyed to the alignment with the insertion base 37, the sleeve 92 is inserted. After insertion, the brush handle 91 continues to be conveyed forward. When the brush handle 91 is conveyed to the alignment with the assembly mechanism 8, the assembly mechanism 8 assembles the brush head 93. After assembly, the brush handle 91 can be unloaded.
