[0002] The associated tubular terminal is a type of cold-pressed terminal, also known as a tubular cold-pressed end or a tubular connection terminal. The associated tubular terminal is a tinned copper sleeve mainly used to fix each strand of a stranded wire. By adding a cold-pressed terminal to a wire, the characteristics of a stranded conductor and a solid conductor can be given, providing a reliable electrical connection, preventing mechanical influence, and facilitating wiring or rewiring. It is widely used in charging systems, control systems, and various electrical equipment of electronic devices and automation equipment.

[0003] When assembling the associated tubular terminal, a copper tube needs to be placed inside the associated sheath, and a special pre-assembly tool is used to pre-press the sheath to ensure that the cutting edge of the ferrule embeds more than 80% of the raised band on the surface of the copper tube covering the end face of the ferrule, and then a crimping pliers is used to perform a secondary crimping on the sheath to form a hexagonal shrinkage structure, realizing the mechanical locking of the copper tube and the sheath.

[0004] However, the existing associated tubular terminals have the following deficiencies during assembly: In the prior art, there is no assembly equipment for associated tubular terminals. The assembly work of the associated sheath and the copper tube needs to be completed manually, relying too much on manual labor, resulting in low assembly efficiency.

The output end of the servo motor 17 is fixedly connected to a speed reducer 18, and the speed reducer 18 is fixedly arranged at the bottom of the workbench plate 20.

[0029] The effects achieved by the entire Embodiment 3 are as follows: For the above-mentioned components, by respectively installing the left support 29, the right support 30 and the main support 31 on the top of the workbench plate 20, and installing the left support 29 and the right support 30 on both sides of the main support 31 respectively, it is convenient to install and connect the forming components, forming a copper tube pressing-in station and a product forming station for the installation and forming work of copper tubes and associated sheaths. The vibrating disc bottom plate 32 is fixedly installed on the top of the workbench plate 20 to facilitate the installation of the feeding vibrating disc 2. The copper tubes placed inside are conveyed along the established track to the pushing slider 10 by the vibration of the feeding vibrating disc 2. The sheath is arranged inside the sheath material groove 8. The crankshaft rod 24 is driven by the servo motor 17 and acts on the copper tube pushing component, moving up and down linearly in cooperation with the forming component to push the copper tube into the inside of the associated sheath. One rotation (360 degrees) of the crankshaft rod 24 is one forming cycle, and two product assemblies are formed in one cycle. During one forming cycle, the crankshaft rotates to drive the upper and lower slider mounting plates to move up and down linearly. The copper tube pushing cam 9 drives the pushing slider 10 to move back and forth, and the sheath positioning stroke cam 27 drives the sheath positioning forming slider 28 to move up and down. The copper tube pushing cam 9 sends the copper tube to the position above the sheath, and the copper tube pushing component moves up and down directly to press the copper tube into the sheath. At the same time, the sheath positioning stroke cam 27 drives the sheath positioning forming slider 28 to move upward and position the associated sheath. The terminal forming component rivets the associated sheath and the copper tube to complete the assembly work of the copper tube and the associated sheath.

[0030] Embodiment 4, according to Figure 1 and Figure 2 As shown, an encoder 19 is fixedly installed at the bottom of the workbench plate 20. There are two synchronous pulleys 21 arranged at the bottom of the workbench plate 20. The connecting shaft of one synchronous pulley 21 is fixedly connected to the main shaft of the encoder 19. A crankshaft support 23 is fixedly installed at the bottom of the workbench plate 20. The output shaft of the reducer 18 is connected to the crankshaft rod 24 through a coupling. The crankshaft rod 24 is inserted through the inside of the crankshaft support 23. The other synchronous pulley 21 is fixedly sleeved on the outer wall of the crankshaft rod 24. A synchronous belt 22 is meshed and connected to the outer walls of the two synchronous pulleys 21. One end of the crankshaft rod 24 is fixedly connected to a crankshaft connecting rod 25. A sheath positioning slider cam 26 is arranged on one side of the crankshaft connecting rod 25. The outer wall of the sheath positioning slider cam 26 is fixedly connected to a sheath positioning stroke cam 27. One end of the sheath positioning stroke cam 27 is fixedly connected to a sheath positioning forming slider 28. A CCD vision inspection camera 7 is fixedly installed on the top of the workbench plate 20. The CCD vision inspection camera 7 is arranged on the top of the sheath material groove 8. A CCD vision inspection computer 16 is arranged on the top of the frame 1. The CCD vision inspection computer 16 is signal-connected to the CCD vision inspection camera 7.

[0031] The effects achieved by the entire Embodiment 4 are as follows: For the components contained above, a servo motor 17 drives a synchronous pulley 21 to rotate. Since the outer walls of the two synchronous pulleys 21 are meshed and connected to a synchronous belt 22, when one of the synchronous pulleys 21 rotates, it will drive the synchronous belt 22 to mesh with the synchronous pulley 21, causing the other synchronous pulley 21 to rotate accordingly. The connecting shaft of the passively rotating synchronous pulley 21 is fixedly connected to the main shaft of an encoder 19 fixedly installed at the bottom of a workbench plate 20. The encoder 19 is used to accurately record and control the rotation angle of the output shaft of the servo motor 17, improving the assembly accuracy. When the servo motor 17 rotates, it will drive a crankshaft rod 24, acting on a copper tube pushing component, and cooperating with a forming component to perform a linear up-and-down movement to push the copper tube into the interior of the coaxial sheath. One rotation (360 degrees) of the crankshaft rod 24 is one forming cycle, and two product assemblies are formed in one cycle. During one forming cycle, the crankshaft rotates to drive an upper and lower slider mounting plate to perform a linear up-and-down movement. A copper tube pushing cam 9 drives a pushing slider 10 to perform a forward and backward movement, and a sheath positioning stroke cam 27 drives a sheath positioning and forming slider 28 to perform an up-and-down movement. The copper tube pushing cam 9 sends the copper tube to a position above the sheath. The copper tube pushing component performs a direct up-and-down movement to press the copper tube into the sheath. At the same time, the sheath positioning stroke cam 27 drives the sheath positioning and forming slider 28 to perform a rising movement and position the coaxial sheath. A terminal forming component rivets the coaxial sheath and the copper tube. When the product riveting is completed and makes a rising movement to 270 degrees, the sheath feeding servo motor 17 completes one feeding action. At the same time, a CCD vision inspection camera 7 is fixedly installed at the top of the workbench plate 20, and a CCD vision inspection computer 16 is fixedly arranged at the top of a frame 1. The CCD vision inspection camera 7 is signal-connected to the CCD vision inspection computer 16. The detection probe of the CCD vision inspection camera 7 is installed above a sheath material tank 8. The assembled coaxial tube-shaped terminal passes under the detection probe of the CCD vision inspection camera 7. The CCD vision inspection camera 7 transmits the detected image data through a signal to the CCD vision inspection computer 16, and the CCD vision inspection computer 16 analyzes and processes the received image data to determine whether the assembly of the copper tube and the coaxial sheath meets the assembly specifications, avoiding the production of defective products.

[0032] The working principle of the entire device is as follows: When the device is in use, according to its functions, it can be divided into a copper tube pressing station, a product forming station, and a sheath feeding station. The three stations are respectively used for pressing the copper tube into the interior of the coaxial sheath, pressing and forming the coaxial sheath and the copper tube, and automatically feeding the coaxial sheath. When the copper tube and the associated sheath are being assembled, first, the copper tube is placed inside the feeding vibrating bowl 2. The feeding vibrating bowl 2 is installed on top of the vibrating bowl bottom plate 32, which plays a supporting role for the feeding vibrating bowl 2. The copper tube placed inside is conveyed along the guide rail to the pushing slider 10 by the vibration of the feeding vibrating bowl 2. The raw material tray 6 is set at one end of the frame 1. The associated sheath inside the raw material tray 6 is unfolded by the pulling and feeding mechanism 5. The sheath is placed inside the sheath material groove 8. The copper tube pushing assembly and the forming assembly are installed on the upper and lower slider mounting plates, forming the copper tube pressing-in station and the product forming station. The servo motor 17 drives the crankshaft rod 24, which acts on the copper tube pushing assembly and cooperates with the forming assembly to move up and down linearly, pushing the copper tube into the inside of the associated sheath. One rotation (360 degrees) of the crankshaft rod 24 is one forming cycle, and two product assemblies are formed in one cycle. During one forming cycle, the crankshaft rotates to drive the upper and lower slider mounting plates to move up and down linearly. The copper tube pushing cam 9 drives the pushing slider 10 to move back and forth, and the sheath positioning stroke cam 27 drives the sheath positioning and forming slider 28 to move up and down. The copper tube pushing cam 9 sends the copper tube to the position above the sheath. The copper tube pushing assembly moves up and down directly, pressing the copper tube into the sheath. At the same time, the sheath positioning stroke cam 27 drives the sheath positioning and forming slider 28 to move upward and position the associated sheath. The terminal forming assembly rivets the associated sheath and the copper tube. When the product riveting is completed and makes an upward movement to 270 degrees, the sheath feeding servo motor 17 completes one feeding action. This process repeats. The assembled associated tubular terminals pass under the detection probe of the CCD vision inspection camera 7. The CCD vision inspection camera 7 transmits the detected image data through a signal to the CCD vision inspection computer 16. The CCD vision inspection computer 16 analyzes and processes the received image data to determine whether the assembly of the copper tube and the associated sheath meets the assembly specifications, avoiding the production of defective products. After the assembly is completed, due to continuous feeding, the assembled associated tubular terminals are conveyed towards the receiving tray 3 connected to the other end of the frame 1. After the receiving tray 3 is opened by the material supporting tray mechanism 4, the receiving tray 3 automatically collects the associated tubular terminals.

[0033] Among them, in the material supporting tray mechanism 4, the material supporting tray mechanism 4 is set on one side of the material receiving tray 3, and the material supporting tray mechanism 4 is used to support the material receiving tray 3, so as to avoid the situation that the material receiving tray 3 is deformed and causes the material receiving tray 3 to become narrower and affect the automatic material receiving.

The width adjusting screw 407 is used to adjust the supporting width of the material receiving tray 3.

[0034] The material pulling and unloading mechanism 5 is used to unfold the associated sheath rolled up inside the raw material disk 6, which solves the problem of the associated sheath being entangled inside the raw material disk 6. The material pulling and unloading mechanism 5 is provided with a fixed bottom plate 501 for installing and fixing the components of the material pulling and unloading mechanism 5, and is installed on one side of the frame 1. An adjusting motor 502 is fixedly installed on one side of the fixed bottom plate 501, and the output end of the adjusting motor 502 is inserted through the inside of the fixed bottom plate 501.
