The spring 70 can enter the guide groove from the guide hole 1122 and the compressed spring 70 can approach the first positioning block 111 along the slide groove 1123, thereby realizing automation instead of manual labor and improving production efficiency.

[0043] like Figure 3As shown, the first loading mechanism 20 includes a first feeding track 202 and a first manipulator 201. The first feeding track 202 is used to convey the shell 60 close to the turntable 11, and the first manipulator 201 is used to pick up the shell 60 to the positioning fixture; specifically, a plurality of first sliders 2021 are slidably arranged side by side on the first feeding track 202, and the shell 60 is placed on the first sliders 2021. Two rows of first sliders 2021 are arranged side by side on the first feeding track 202. The two ends of the first feeding track 202 along the length direction respectively have a pushing cylinder 2022 and a moving cylinder 2023. The pushing cylinders 2022 at both ends push the first slider 2021 to approach or leave the first manipulator 201, and the moving cylinders 2023 at both ends push the first slider 2021 to move on both sides of the first feeding track 202 , the pushing cylinder 2022 away from the first manipulator 201 pushes the first slider 2021 on which the shell 60 is placed to move toward the first manipulator 201, and the parallel first sliders 2021 move one by one to the bottom of the first manipulator 201. After the first manipulator 201 picks up the shell 60, the moving cylinder 2023 pushes the first slider 2021 toward another row, and the pushing cylinder 2022 close to one end of the first manipulator 201 pushes the empty first slider 2021 to move toward the side away from the first manipulator 201. The shell 60 is manually placed on the first slider 2021, and the moving cylinder 2023 pushes the first slider 2021 with the shell 60 placed to enter the next cycle. The first manipulator 201 picks up the shell 60 in turn and places it on the first positioning block 111, thereby realizing automatic feeding of the shell 60.

[0044] like Figure 4-7 As shown, the second feeding mechanism 30 includes a second feeding track 302 and a second manipulator 301. The second feeding track 302 is used to convey the spring 70 close to the turntable 11, and the second manipulator 301 is used to pick up the spring 70 and place it on the positioning fixture; specifically, a second slider 3021 is slidably installed on the second feeding track 302, and a plurality of arc-shaped notches 3022 are opened on one side of the second slider 3021 along the length direction. A vibration plate 303 is installed on one side of the second feeding track 302, and the arc-shaped notch 3022 faces the vibration plate 303. The second slider 3021 moves back and forth between the vibration plate 303 and the second manipulator 301, and the vibration plate 303 automatically transfers the springs 70 one by one to the second slider 3021. In this embodiment, there are three arc-shaped notches 3022. When the three arc-shaped notches 3022 are filled with three springs 70, they move toward the second manipulator 301 to realize automatic loading of the springs 70. In this embodiment, the second feeding track 302 includes two and the vibration plate 303 includes two, which improves the feeding efficiency of the springs 70, avoids manual sorting of entangled springs, and improves production efficiency.

[0045] like Figure 4-7As shown, the second manipulator 301 includes a base plate 3011, a movable plate 3013 and a ejector pin 3015. The base plate 3011 is provided with an inverted conical hole 3012. The movable plate 3013 is movably arranged on the base plate 3011. A magnetic block is arranged on the movable plate 3013. The ejector pin 3015 is vertically movably arranged above the inverted conical hole 3012. Specifically, the second manipulator 301 includes a slide rail that can move horizontally, and the slide rail moves between the second feeding track 302 and the positioning fixture. The bottom plate 3011 is installed on the slide rail, and the bottom plate 3011 is provided with an inverted conical hole 3012. A horizontal cylinder is installed on the side of the bottom plate 3011, and the piston rod of the horizontal cylinder is connected to the movable plate 3013. The magnet 3014 is installed on the movable plate 3013. The horizontal cylinder can push the movable plate 3013 to move on the bottom plate 3011, and drive the magnet 3014 to approach or leave the inverted conical hole 3012. In this embodiment, the bottom plate 3011 is provided with three inverted conical holes 3012, and three magnets 3014 are installed on the corresponding movable plates 3013. A cylinder for an ejector pin 3015 is installed on the bottom plate 3011, and the piston rod of the cylinder for the ejector pin 3015 is connected to the ejector pin 3015, and the ejector pin 3015 can penetrate into or leave the inverted conical hole 3012. The control slide rail moves to the top of the second slider 3021, and the bottom plate 3011 moves downward so that the conical hole covers the spring 70 in the arc-shaped notch. The control horizontal cylinder pushes the movable plate 3013 to drive the magnet 3014 to be placed one by one on the inverted conical hole 3012. The magnet 3014 attracts the spring 70 in the arc-shaped notch 3022 to the inverted conical hole 3012. The slide rail moves horizontally to the second positioning block 112, and the control horizontal cylinder drives the magnet 3014 to horizontally leave the top of the inverted conical hole 3012. After losing the magnetic attraction, the spring 70 will fall into the second positioning block 112, and then the ejector pin 3015 cylinder is controlled to press down to drive the ejector pin 3015 to penetrate into the inverted conical hole 3012, ensuring that the spring 70 is placed from the inverted conical hole 3012 to the second positioning block 112, thereby realizing automatic feeding of the spring 70 to the second positioning block 112.

[0046] like Figure 8As shown, the assembly mechanism 40 includes a pressing cylinder 401 and a pushing cylinder 402. The piston rod of the pressing cylinder 401 is installed with a pressing rod 4011, and the piston rod of the pushing cylinder 402 is installed with a pushing rod 4021. The pressing rod 4011 is used to compress the spring 70, and the pushing rod 4021 is used to push the compressed spring 70 into the shell 60. Specifically, when the turntable 11 rotates and drives the positioning fixture equipped with the shell 60 and the spring 70 to move to the bottom of the pressing cylinder 401, the pressing cylinder 401 is controlled to push the pressing rod 4011 to compress the spring 70 along the guide hole 1122, and then the pushing cylinder 402 is controlled to drive the pushing rod 4021 to push the compressed spring 70 along the slide groove 1123 into the shell 60, thereby realizing the automatic installation of the spring 70. Furthermore, the assembly mechanism 40 further includes two positioning rods 403, which are installed on the piston rod of the pressing cylinder 401. When the pressing cylinder 401 extends downward, it pushes the pressing rod 4011 downward and pushes the positioning rod 403 to press the shell 60, thereby preventing the shell 60 from being moved due to the force during the process of the push rod 4021 pushing the spring 70 into the shell 60, resulting in the spring 70 being unable to be installed.

[0047] like Fig. 9 As shown, the unloading mechanism 50 includes a third manipulator 501 and a feeding belt 502. The third manipulator 501 is used to move the movement after the spring 70 is installed from the positioning fixture to the feeding belt 502. The feeding belt 502 conveys the movement away from the turntable 11. Specifically, when the turntable 11 drives the movement after the spring 70 is installed to move close to the third manipulator 501, the third manipulator 501 picks up the movement and places it on the feeding belt 502. The feeding belt 502 sends the movement to the side away from the turntable 11. Further, the unloading mechanism 50 further includes a movable sensor 503 installed on one side of the feeding belt 502. Specifically, a cylinder is installed on one side of the feeding belt 502, and the piston rod of the cylinder is installed with the sensor 503. When the third manipulator 501 picks up the shell after the spring is installed and moves close to the sensor 503, the sensor 503 can detect whether there is a spring installed in the shell, which plays a detection role. The cylinder can drive the sensor 503 to approach the manipulator.

[0048] The turntable 11 of the utility model drives the positioning jig to pass through the first loading mechanism 20, the second loading mechanism 30, the assembly mechanism 40 and the unloading mechanism 50 in sequence. The first loading mechanism 20 is used to move the shell 60 to the positioning jig, the second loading mechanism 30 is used to move the spring 70 to the positioning jig, the assembly mechanism 40 installs the spring 70 into the shell 60, and the unloading mechanism 50 is used to remove the movement with the spring 70 installed from the positioning jig, and the belt body is manually installed to automatically install the spring 70 into the movement.
