[0018] By using the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0019] The system comprises an inner tube conveying device, an intermediate tube conveying device, and an outer tube conveying device. The inner tube conveying device transports the inner tube to the first tube-passing assembly. The intermediate tube conveying device transports the intermediate tube to the first tube-passing assembly via a first tube transfer mechanism. The inner tube and intermediate tube converge at the first tube-passing assembly and are assembled to form a combined pipe fitting. Before being transported to the first tube-passing assembly, the intermediate tube undergoes a first tube indentation mechanism to indent one end. The inner tube is first transported to the first tube-passing assembly via a small locking block feeding group. The small locking block is installed in the inner tube; after the combined pipe fitting is formed, it is transported to the second pipe-passing assembly by the first pipe transfer mechanism. Simultaneously with the transport and assembly of the inner and intermediate pipes, the outer pipe transport device moves synchronously. The outer pipe transport device transports the outer pipe to the second pipe-passing assembly via the second pipe transfer mechanism. Since a second pipe creasing mechanism and a large outer sleeve pipe-passing assembly are sequentially arranged between the second pipe-passing assembly and the outer pipe unloading mechanism, the outer pipe is first creasing one end by the second pipe creasing mechanism before being transported to the second pipe-passing assembly, and then the large outer sleeve pipe-passing assembly is used for pipe-passing. The assembly installs the large outer sleeve onto one end of the outer tube. Then, the second tube transfer mechanism transports the processed outer tube to the second tube insertion assembly. At this point, the outer tube and the constituent tubes intersect, and the second tube insertion assembly assembles them into a telescopic tube. The assembled telescopic tube is then transported again by the second tube transfer mechanism, sequentially passing through the small outer sleeve insertion assembly, the end cap insertion assembly, the handle insertion assembly, the hook block insertion assembly, the telescopic tube reset assembly, and the final assembly assembly. The small outer sleeve insertion assembly is used to install the small outer sleeve into the middle of the telescopic tube. On the inner tube, the end cap insertion assembly is used to install the end cap on the outer tube of the telescopic tube away from the outer sleeve; the handle insertion assembly is used to fit the handle onto the end of the outer tube; the hook block insertion assembly is used to lock the hook block onto one end of the handle; the telescopic tube reset assembly is used to reset all the components of the telescopic tube; and the final assembly assembly is used to install the connector on one end of the inner tube. After all the assembly processes are completed, the second tube transfer mechanism transports the assembled telescopic rod to the unloading rack, from where the assembled telescopic rod is unloaded into the finished product storage assembly. By using a fully automated production line to assemble the telescopic rod in this way, production efficiency is improved, production costs are reduced, and product quality is stabilized. This solves the technical problems of low production efficiency, high cost, and difficulty in guaranteeing quality associated with the existing manual assembly of telescopic rods.

A small locking block feeding gear 2003 is provided on the rotating shaft of the feeding turntable 2001. A feeding mechanism is provided at the end of the small locking block feeding tray fixing frame 2000 away from the feeding turntable 2001. A turntable drive motor 2004 has a feeding turntable transmission gear 2005 on its drive end. The feeding turntable transmission gear 2005 meshes with a small locking block feeding gear 2003. The feeding turntable drive motor 2004 drives the feeding turntable 2001 to rotate. The feeding turntable 2001 has several through holes on its upper ring, each containing a feeding shaft 2006. The feeding shaft 2006 is hollow inside and used to hold small locking blocks. It has a discharge hole and an outlet hole at both ends. A small locking block feeding disc fixing bracket is also included. The feeding plate 2000 is equipped with a discharge baffle 2007, which is arranged around one end of the discharge hole of the feeding turntable 2001 and covers the discharge holes of the feeding shaft 2006 except for the topmost one. The small locking block push cylinder 2002 is installed on one side of the top of the small locking block feeding plate fixing frame 2000. Its pushing end is corresponding to the discharge hole of the uppermost feeding shaft 2006 of the feeding turntable 2001, and also corresponds to the small locking block docking shaft 2003. The small locking block docking shaft 2003 includes a pressing part and a connecting part. The mating part and the connecting part are integrally formed. The small locking block docking shaft 2003 is fixedly mounted on the small locking block feeding plate fixing frame 2000 through the connecting part. One end of the connecting part is provided with a material hole, which extends into the pressing part and passes through it. In this embodiment, the material hole of the connecting part is close to the discharge hole of the top feeding shaft 2006 of the feeding turntable 2001. In addition, the feeding plate fixing frame 2000 is also provided with a proximity switch for detecting whether the top feeding shaft 2006 is in place. The proximity switch is used to drive the small locking block pushing cylinder 2002 to feed the material.

[0052] In this embodiment, the first drilling assembly 202 includes an upper drilling cylinder 2008 and a lower drilling cylinder 2009. The upper drilling cylinder 2008 and the lower drilling cylinder 2009 are respectively disposed at the upper and lower ends of the pressing part. Drilling grooves 2010 are provided at the upper and lower ends of the pressing part. A plurality of upper dotting shafts 2011 and lower dotting shafts 2012 are respectively provided on the pushing ends of the upper drilling cylinder 2008 and the lower drilling cylinder 2009.

[0053] In this embodiment, the receiving component 205 includes several receiving transition blocks 2013 and transition block pushing cylinders 2014. The top of the receiving transition block 2013 is provided with a V-shaped groove, and the bottom of the receiving transition block 2013 is provided with a transmission rod. The transmission rod is connected to a lifting plate 2015. The driving end of the transition block pushing cylinder 2014 is connected to the lifting plate 2015. Specifically, there are three sets of receiving transition blocks 2013, and a non-liftable V-shaped nylon support block 2016 is provided between adjacent receiving transition blocks 2013.

[0054] The above process is as follows: First, the inner tube is placed in the storage cavity of the unloading rack 101. Then, the inner tube is unloaded through the storage cavity to the discharge port of the unloading rack 101. At this time, the pushing assembly 103 is driven to unload the inner tube onto the V-shaped nylon feeding block and the tube support assembly below it. Since the tube support assembly is equipped with a proximity switch, when the inner tube falls onto it, the proximity switch is triggered, causing the inner tube unloading cylinder connected to the V-shaped nylon feeding block to move, so as to move the V-shaped nylon feeding block towards the receiving assembly 205 and place it on the non-liftable V-shaped nylon support block 2016. Then, it is reset. Next, the receiving transition block 2013 is lifted upward by the transition block pushing cylinder 2014, so that a pushing channel is formed between the receiving transition block 2013 and the V-shaped nylon support block 2016. The two ends of the pushing channel are respectively connected to the material hole of the docking shaft 2003 of the small locking block and the docking shaft hole on the stand 203. Correspondingly, small locking blocks are simultaneously placed into the feeding shaft 2006 by manual feeding. The feeding turntable 2001 is driven to rotate by the feeding turntable drive motor 2004, rotating the feeding shaft 2006 containing the small locking blocks to its top position. This aligns the small locking blocks inside the feeding shaft 2006 with the pushing end of the small locking block push cylinder 2002 and the material hole of the small locking block docking shaft 2003. Then, the inner tube in the inner tube conveying assembly 204 is fed into the assembly to convey the inner tube. The tube is pushed into the small locking block docking shaft 2003. Then, the small locking block pushing cylinder 2002 is activated to push the small locking block into the inner tube located in the small locking block docking shaft 2003 via the feeding shaft 2006. After that, the end of the inner tube is punched by the cooperation of the upper punching cylinder 2008 and the lower punching cylinder 2009 to limit the small locking block in the inner tube. Finally, the inner tube conveying assembly 204 pushes out the inner tube with the small locking block installed.

[0068] like Figure 13-14 As shown: The large outer sleeve bracket 903 is provided with a material groove. One end of the material groove corresponds to the left push block 906 of the large sleeve, and the other end corresponds to the guide hole on the first clamping frame 904. It also includes a large outer sleeve feeding mechanism, and the feeding end of the large outer sleeve feeding mechanism is correspondingly set at the material groove.

[0069] The working principle of the mechanism is as follows: First, the large outer jacket feeding mechanism (not shown in the figure), in this embodiment, is a vibrating feeding plate, which feeds the large outer jacket through the conveying pipe into the material trough on the large outer jacket bracket 903. Then, the right push block 907 on the right pressing cylinder 902 pushes the outer tube into the large sleeve docking shaft, so that the outer tube and the large outer jacket correspond to each other. Next, the left pressing cylinder 901 pushes the left push block 906 on its pushing end to fix the outer tube and the large outer jacket to each other. Then, the outer tube with the large outer jacket installed is placed back on the support assembly.

The final left pressing assembly includes a final movable panel 1601 movably arranged on the production line frame 20. A push cylinder for driving the movement of the final movable panel 1601 is provided below the final movable panel 1601. The final movable panel 1601 is provided with a final left pressing cylinder 1602 and a final docking fixing plate 1603. A final bracket 1604 is provided between the final left pressing cylinder 1602 and the final docking fixing plate 1603. An external plastic part feeding mechanism is connected to the final bracket 1604. The final right pressing assembly includes a final assembly frame 1605. A final positioning cylinder 1606 is provided on the final assembly frame 1605. A combined tube support frame is correspondingly provided below the final positioning cylinder 1606.

[0072] In this embodiment, the final movable panel 1601 moves on the fixed base plate of the production line frame 20 through the cooperation of the slider and the slide rail. The final assembly frame 1605 is provided with a final elevation block for abutting the telescopic tube. The working principle of the final assembly component 16 is as follows: First, the assembled telescopic tube is transported to the combined tube support frame. The push block on the push end of the final positioning cylinder 1606 corresponds to the support frame. The telescopic tube on the support frame is pushed into the final threaded head docking shaft located on the final docking fixing plate 1603 by the final positioning cylinder 1606. Then, the push end of the final left pressing cylinder 1602 pushes the threaded head located on the final bracket 1604 into the final threaded head docking shaft to complete its assembly with the telescopic rod and reset the assembled telescopic rod. In addition, the final bracket 1604 is connected to a vibrating feeding plate through a conveying pipe.

[0073] Between the final assembly assembly 16 and the pressure hook block tube insertion assembly 14, a telescopic tube reset assembly 15 is also provided. The telescopic tube reset assembly 15 includes a reset push cylinder and a cylinder positioning plate for installing the reset push cylinder. On the other side of the second tube transfer mechanism 7, a reset abutment plate is provided. The reset abutment plate and the push end of the reset push cylinder are corresponding, and a support assembly for placing the telescopic rod is provided between the reset abutment plate and the cylinder positioning plate.

[0074] like Figure 1-2 As shown: Downstream of the final assembly component 16, there is an unloading rack 18, and the finished product storage component 17 is placed below the unloading rack 18. In this embodiment, the unloading rack 18 includes a first frame and a second frame. The first frame and the second frame are used to support the two ends of the telescopic tube. One end of the first frame and the second frame is inclined downward to facilitate the guidance of the assembled telescopic tube into the finished product storage component 17. In this embodiment, the finished product storage component 17 is a storage box.

[0075] The workflow and principle of this invention are as follows:

[0076] By setting up an inner tube conveying device, an intermediate tube conveying device, and an outer tube conveying device, the inner tube conveying device is used to convey the inner tube to the first tube insertion assembly 2. The intermediate tube conveying device conveys the intermediate tube to the first tube insertion assembly 2 through the first tube transfer mechanism 4. The inner tube and the intermediate tube meet at the first tube insertion assembly 2 and are assembled into a combined pipe fitting through the first tube insertion assembly 2. In addition, before the intermediate tube is conveyed to the first tube insertion assembly 2, one end of the intermediate tube is first indented by the first tube indentation mechanism 5. When the inner tube is conveyed to the first tube insertion assembly 2, it is first indented by the small locking block feeding assembly 201. The clamping block is installed in the inner tube; after the combined pipe fitting is formed, it is transported to the second pipe-through assembly 10 by the first pipe transfer mechanism 2. While the inner tube and intermediate tube are being transported and assembled, the outer tube transport device moves synchronously. The outer tube transport device transports the outer tube to the second pipe-through assembly 10 through the second pipe transfer mechanism 7. Since the second pipe creasing mechanism 8 and the outer tube pressing outer sleeve pipe-through assembly 9 are arranged sequentially between the second pipe-through assembly 10 and the outer tube unloading mechanism 6, the outer tube will be creasing one end by the second pipe creasing mechanism 8 before being transported to the second pipe-through assembly 10. Then, the outer tube pressing outer sleeve pipe-through assembly 9 will press the outer tube. The outer tube is installed at one end of the outer tube, and then the processed outer tube is transported to the second tube insertion assembly 10 by the second tube transfer mechanism 7. At this time, the outer tube and the component tube intersect and are assembled into a telescopic tube by the second tube insertion assembly 10. The assembled telescopic tube is transported again by the second tube transfer mechanism 7 and passes through the small outer sleeve insertion assembly 11, the pressure end cap insertion assembly 12, the pressure handle insertion assembly 13, the pressure hook block insertion assembly 14, the telescopic tube reset assembly 15, and the final assembly assembly 16 in sequence. The small outer sleeve insertion assembly 11 is used to install the small outer sleeve in the middle of the telescopic tube. On the tube, the end cap insertion assembly 12 is used to install the end cap on the outer tube of the telescopic tube away from the outer sleeve; the handle insertion assembly 13 is used to fit the handle onto the end of the outer tube; the hook block insertion assembly 14 is used to lock the hook block onto one end of the handle; the telescopic tube reset assembly 15 is used to reset each component of the telescopic tube; and the final assembly assembly 16 is used to install the connector onto one end of the inner tube. After each assembly process is completed, the second tube transfer mechanism 7 transports the assembled telescopic rod to the unloading rack 18, and the unloading rack 18 lowers the assembled telescopic rod into the finished product storage assembly 17. By using the above method to assemble the telescopic rod on a fully automated production line, production efficiency is improved, production costs are reduced, and product quality is stabilized. This solves the technical problems of low production efficiency, high cost, and difficulty in guaranteeing quality when using manual assembly methods for existing telescopic rods.
