Description

Technical Field

[0001] This utility model relates to the field of automated intelligent production equipment for functional pipe fittings, specifically to a pipe end cap assembly device. Background Technology

[0002] A functional pipe fitting is needed, comprising: a straight pipe with a locking head inserted at one end, and a rivet point at the end of the pipe with the locking head to secure it; an end cap at the other end of the pipe, with a ring of glue applied to the inner wall of the end cap before assembly to secure it to the end of the pipe; and an intermediate section pre-installed on the straight pipe. All three components—the locking head, end cap, and intermediate section—are made of plastic. Currently, the installation of these three plastic components is done manually. Manual installation of plastic components suffers from low processing efficiency, high labor costs, and inconsistent assembly quality. To achieve automated production, there is an urgent need for a pipe end cap assembly device suitable for automated production lines that can automatically install end caps. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pipe end cap assembly device that can automatically install end caps on an automated production line.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a pipe end cap assembly device, comprising: a frame, characterized in that: an end cap mounting seat that can slide left and right and an end cap pushing mechanism that can drive the end cap mounting seat to move left and right are provided on the frame; an end cap feeding finger arranged horizontally in a front-back direction and a first end cap rotating cylinder that can drive the end cap feeding finger to swing back and forth 180 degrees upwards; a glue applicator that can slide left and right and a glue applicator driving mechanism that can drive the glue applicator to move left and right; a rotating seat and a second end cap rotating cylinder that can drive the rotating seat to rotate back and forth horizontally 180 degrees backwards; and a... The system includes a pusher column and a pusher drive mechanism that drives the pusher column to move left and right; a horizontally arranged end cap gripping finger and a third end cap rotary cylinder that drives the end cap gripping finger to swing back and forth 180 degrees upwards; an end cap glue-applying finger and a glue-applying rotation mechanism that drive the end cap glue-applying finger to rotate on a rotating base; the end cap glue-applying finger is located inside the glue-applying machine; the end cap gripping finger is located between the end cap glue-applying finger and the pusher column; the pusher column is located in front of the end cap gripping finger; the end cap feeding finger can grip the end cap perpendicular to the end cap axis; and after swinging 180 degrees, it can transfer the gripped end cap to the glue-applying machine and the end cap glue-applying finger. Between these steps, the outer end cap glue-applying fingers then coaxially grasp the tail end of the end cap, transferring it to the glue-applying fingers. Driven by the glue-applying drive mechanism, the glue applicator moves inward, inserting its glue-applying tube into the end cap. Driven by the glue-applying rotation mechanism, the glue-applying fingers rotate the end cap 360 degrees, applying a ring of glue to the inner wall of the end cap. After the glue-applying tube leaves the end cap, the glue-applying fingers, driven by the second end cap rotating cylinder, swing the end cap 180 degrees horizontally backward, turning inward. At this point, the glued end cap is transferred between the two fingers of the end cap grasping fingers. The end cap gripping fingers can grip the glued end cap perpendicularly to the end cap axis, allowing the end cap to be transferred to the gripping fingers. Then, driven by the third end cap rotary cylinder, the gripping fingers swing upwards 180 degrees, and the glued end cap is moved to the opposite side of the push column. Next, driven by the end cap push mechanism, the end cap mounting seat moves towards the positioned left-right straight pipe. The end cap held by the gripping fingers can be shallowly placed on the end of the straight pipe under the drive of the end cap mounting seat. After the gripping fingers release the end cap, the push column can push the end cap under the drive of the push drive mechanism, so that the end cap is properly installed on the end of the straight pipe.

[0005] Furthermore, the aforementioned pipe end cap assembly device further includes an end cap supply mechanism. The end cap supply mechanism comprises an end cap vibrating plate for providing end caps, an end cap conveying channel on the end cap vibrating plate, and end caps conveyed outward by the end cap vibrating plate sliding downward and arranging in the end cap conveying channel. An avoidance notch is provided at the lower end of the end cap conveying channel, and the end cap feeding fingers can pass through the avoidance notch to grip the first end cap arranged in the end cap conveying channel from top to bottom. Furthermore, due to the open upper surface at the lower end of the end cap conveying channel and the baffle at the lower port of the end cap conveying channel being set as an arc-shaped plate that can avoid the end caps, the end cap feeding fingers can swing upward under the drive of the first end cap rotating cylinder and bring the gripped end cap away from the end cap conveying channel.

[0006] Furthermore, in the aforementioned pipe end cap assembly device, an end cap stop block and an end cap stop block driving mechanism are provided above the lower end of the end cap conveying channel. After the end cap stop block moves downward under the drive of the end cap stop block driving mechanism, it can press the second end cap arranged in the end cap conveying channel, so that the end cap can leave the end cap conveying channel without hindering the first end cap from being arranged in the end cap conveying channel.

[0007] Furthermore, in the aforementioned pipe end cap assembly device, the structure of the glue-applying rotation mechanism is as follows: a horizontally arranged, rotatable drive shaft and a servo motor are mounted on a rotating base; the end cap glue-applying fingers are fixed to one end of the drive shaft; and synchronous pulleys are fixed to the output shaft of the servo motor and the other end of the drive shaft; the servo motor and the drive shaft are driven by a synchronous belt.

The straight pipe is supported and positioned on the frame in a left-right direction by being clamped by the two wide-type cylinder fingers at both ends. The backing plate can provide abutment for the straight pipe when the end cap is installed. The fourth backing drive mechanism can drive the backing plate away from the straight pipe so as not to hinder the transfer of the straight pipe.

[0010] Furthermore, in the aforementioned pipe end cap assembly device, the end cap conveying channel is fixed on a linear vibrator.

[0016] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the pipe end cap assembly device includes: a frame 1, on which is mounted a left-right sliding end cap mounting seat 2 and an end cap pushing mechanism that drives the end cap mounting seat 2 to move left and right; a horizontally arranged end cap feeding finger 3 and a first end cap rotary cylinder 4 that drives the end cap feeding finger 3 to swing back and forth 180 degrees upwards; a left-right sliding glue applicator 5 and a glue applicator driving mechanism 18 that drives the glue applicator 5 to move left and right; a rotating seat 6 and a second end cap rotary cylinder 7 that drives the rotating seat 6 to rotate back and forth horizontally 180 degrees backwards; the end cap mounting seat 2 and the glue applicator 5 are both mounted on the frame 1 via linear guide rails; and a pushing column 8 and a mechanism that drives the pushing column are provided on the end cap mounting seat 2. The system includes a left-right moving push-drive mechanism 19, a horizontally arranged end cap gripping finger 9, and a third end cap rotary cylinder 10 that drives the end cap gripping finger 9 to swing back and forth 180 degrees upwards. An end cap glue-applying finger 11 and a glue-applying rotation mechanism for driving the end cap glue-applying finger 11 to rotate are mounted on a rotating base 6. The end cap glue-applying finger 11 is located inside the glue applicator 5. The end cap gripping finger 9 is located between the end cap glue-applying finger 11 and the push column 8, with the push column 8 located in front of the end cap gripping finger 9. The end cap feeding finger 3 can grip the end cap 20 perpendicular to the end cap axis, and after swinging 180 degrees, it can move the gripped end cap 20 between the glue applicator 5 and the end cap glue-applying finger 11, then turn outwards. The end cap glue-applying finger 11 can coaxially grasp the tail end of the end cap 20, thus transferring the end cap 20 to the end cap glue-applying finger 11. Driven by the glue-applying drive mechanism 18, the glue-applying machine 5 moves inward, and its glue-applying tube is inserted into the end cap 20. Driven by the glue-applying rotation mechanism, the end cap glue-applying finger 11 rotates the end cap 20 360 degrees, applying a ring of glue to the inner wall of the end cap 20. After the glue-applying tube leaves the end cap 20, the end cap glue-applying finger 11, driven by the second end cap rotating cylinder 7, swings the end cap 20 horizontally backward 180 degrees and then turns inward. At this point, the glued end cap 20 can be transferred between the two fingers of the end cap grasping finger 9. Then, the end cap grasping finger... The end cap 20, after being glued, can be gripped vertically along the end cap axis, so that the end cap 20 can be transferred to the end cap gripping finger 9. Then, the end cap gripping finger 9 swings upward 180 degrees under the drive of the third end cap rotating cylinder 10, and the glued end cap 20 can be transferred to the opposite side of the pushing column 8. Then, the end cap mounting seat 2 moves towards the positioned left-right straight tube 23 under the drive of the end cap pushing mechanism. The end cap 20, held by the end cap gripping finger 9, can be shallowly covered on the end of the straight tube 23 under the drive of the end cap mounting seat 2. After the end cap gripping finger 9 releases the end cap 20, the pushing column 8 can push the end cap 20 under the drive of the pushing drive mechanism 19, so that the end cap 20 can be installed in place on the end of the straight tube 23.

[0018] In this embodiment, an end cap supply mechanism is also provided. The structure of the end cap supply mechanism includes: an end cap vibrating plate 14 for providing end caps, an end cap conveying channel 15 provided on the end cap vibrating plate 14, and the end caps 20 conveyed outward by the end cap vibrating plate 14 will slide downward and be arranged in the end cap conveying channel 15. An avoidance notch is provided on the lower end of the end cap conveying channel 15. The end cap feeding finger 3 can pass through the avoidance notch to grip the first end cap 20 arranged in the end cap conveying channel 15 from the top and bottom. Since the upper surface of the lower end of the end cap conveying channel 15 is open and the baffle on the lower port of the end cap conveying channel 15 is set as an arc plate that can avoid the end cap 20, the end cap feeding finger 3 can swing upward under the drive of the first end cap rotating cylinder 4 and bring the gripped end cap 20 away from the end cap conveying channel 15. Since the first end cover rotary cylinder 4 swings upward to remove the end cover 20, if the baffle on the lower port of the end cover conveying channel 15 is a straight plate, the end cover 20 will collide with the upper part of the baffle when it is removed. Setting the baffle as an arc plate can avoid the collision.

[0019] To prevent the end cap 20 from being affected by the next end cap 20 when it is being carried away, an end cap stop block 17 and an end cap stop block drive mechanism 16 that can drive the end cap stop block 17 to move up and down are provided above the lower end of the end cap conveying channel 15. After the end cap stop block 17 moves downward under the drive of the end cap stop block drive mechanism 16, it can press the second end cap 20 arranged in the end cap conveying channel 15, so that the end cap 20 can leave the end cap 20 arranged in the first position without hindering it from leaving the end cap conveying channel 15.

[0020] The structure of the glue-applying rotating mechanism is as follows: a horizontally arranged, rotatable transmission shaft 12 and a servo motor 13 are installed on the rotating base 6. The end cap glue-applying finger 11 is fixed to one end of the transmission shaft 12. Synchronous pulleys are fixed on the output shaft of the servo motor 13 and the other end of the transmission shaft 12. The servo motor 13 and the transmission shaft 12 are driven by the synchronous belt.

[0021] Two air passages are provided in the drive shaft 12. The outer ports of the two air passages are located on the end face of the drive shaft 12 where it is fixed to the end cap glue-applying finger 11, and the two outer ports are respectively connected to two air ports on the tail end of the end cap glue-applying finger 11. The inner ports of the two air passages are staggered and located on the side wall of the drive shaft 12. Two annular air grooves are provided on the side wall of the through hole of the drive shaft 12 on the rotating seat 6. The two annular air grooves are respectively connected to the inner ports of the two air passages. Two air inlets are provided on the side wall of the rotating seat 6, which are respectively connected to the two annular air grooves. The air pipes used to control the movement of the end cap glue-applying finger 11 are respectively connected to the two air inlets. This arrangement is to supply air to the end cap glue-applying finger 11 so that it can open and close.

[0022] To position the straight tube 23, two wide-shaped cylinder fingers 21 aligned horizontally are provided on the frame 1, along with a stop plate 22 and a fourth abutment drive mechanism that can drive the stop plate 22 to move left and right. The straight tube is supported and positioned on the frame 1 by being clamped at both ends by the two wide-shaped cylinder fingers 21. The stop plate 22 provides support for the straight tube 23 when the end cap 20 is installed. The fourth abutment drive mechanism can drive the stop plate 22 away from the straight tube 23 so as not to obstruct the transport of the straight tube 23. For better transport of the end cap 20, the end cap transport channel 15 is fixed to the linear vibrator.

[0023] In this embodiment, the end cap pushing mechanism, the glue application driving mechanism 18, the pushing driving mechanism 19, the end cap stop block driving mechanism 16, and the fourth abutting driving mechanism are all cylinders. The end cap feeding finger 3, the end cap gripping finger 9, and the end cap glue application finger 11 are all pneumatic fingers.
