[0065] The technical solution protected by the present invention is described in detail below with reference to the accompanying drawings.

[0066] like Figure 3 As shown, an automated assembly device for a barber razor charger base comprises: a workbench, on which a rotary conveyor disc 13 is provided, on which a plurality of product jigs 14 are provided, and along which an upper cover loading station 2, a decorative ring loading station 3, a pre-pressing station 4, a base loading station 5, a PIN needle loading station 6, a shrapnel loading station 7, a counterweight loading station 8, a CCD detection station 9, an assembly station 10, a defective product unloading station 11 and a good product unloading station 12 are sequentially provided.

[0067] Among them, the upper cover loading station 2 and the decorative ring loading station 3 have the same structure, and the difference lies in the shapes of their clamping jaws, which are respectively adapted to the shapes of the upper cover and the decorative ring.

[0068] In this embodiment, a transfer temporary storage mechanism is respectively provided between the upper cover loading station 2, the decorative ring loading station 3 and the rotary conveyor plate 13, so as to improve the operation efficiency of the rotary conveyor plate.

[0069] like Figure 4 As shown, the upper cover loading station 2 and the decorative ring loading station 3 have the same structure, both comprising a stacking and feeding mechanism A21 and a mobile module A22 positioned above the frame. The mobile end of mobile module A22 has a lifting assembly, and the lower end of the lifting assembly is equipped with a gripper A23 for gripping products. The gripper A23 picks up product components from the tray and places them in a temporary transfer mechanism. The gripper at the temporary transfer mechanism then grabs and places them into the product jig 14 on the rotating conveyor tray.

[0070] like Figure 5As shown, the upper cover loading station 2 and the decorative ring loading station 3 respectively feed the upper cover 101 and the decorative ring 102 into the product fixture 14 of the rotary conveyor disk, and then the two are first pressed by the pre-pressing station 4. The pre-pressing station 4 includes: a fixed plate, a pre-pressing cylinder 41 is provided on the top of the fixed plate, the piston rod of the pre-pressing cylinder 41 is provided downward and a lifting plate 42 is provided at the end of the piston rod, a pre-pressing guide rail 43 and a matching pre-pressing slider 44 are provided on the lifting plate 42 near the rotary conveyor disc 13, a pre-pressing head 45 is provided on the pre-pressing slider 44, the shape of the pre-pressing head 45 matches the upper cover 101, the position of the pre-pressing head 45 corresponds to the product fixture 14 at the rotary conveyor disc, a buffer spring 46 is provided between the pre-pressing head 45 and the lifting plate 42, when the product fixture 14 equipped with the upper cover 102 and the decorative ring 103 reaches the pre-pressing station 4 on the rotary conveyor disc 13, the pre-pressing head 45 descends and presses the two together. The buffer spring 46 is provided to provide a buffering function to prevent the upper cover 102 or the decorative ring 103 from being crushed.

[0071] like Figure 6 、 Figure 7 As shown, the base loading station 5 includes: a stacking feeding mechanism C51, a mobile module C52 arranged above the frame table, the mobile end of the mobile module C52 has a lifting component, and a clamping claw C53 for clamping the product is provided at the lower end of the lifting component, and the clamping claw C53 is also provided with a rotating mechanism;

[0072] The difference between the base loading station 5 and the upper cover loading station 2 and the decorative ring loading station 3 is that a CCD camera 54, a temporary storage plate 55, and a material removal assembly are provided between the base loading station 5 and the rotary conveyor plate 13; the CCD camera 54 is used to detect the position of the base 103. When the position of the base during loading does not match the set value, the rotating mechanism at the clamping claw C53 drives the base to rotate to the set value, and then the base is placed on the temporary storage plate 55;

[0073] The temporary storage plate 55 includes at least two material discharge positions, and a first rotary cylinder 56 is provided at the bottom of the temporary storage plate 55; the first rotary cylinder 56 is provided to enable material to be loaded and unloaded at the same time, thereby improving the loading efficiency.

[0074] The material removal assembly includes a lifting cylinder C511 with an upward-facing piston rod. A lifting plate C510 is mounted at the end of the piston rod. A second rotary cylinder 59 is fixed to the lifting plate C510. Matching sliders and guide rails are provided between the second rotary cylinder 59 and the lifting plate C510, facilitating smoother lifting and lowering of the second rotary cylinder 59. The movable end of the second rotary cylinder 59 is connected to a loading clamp 57 via a crossbeam 58. The loading clamp 57 grasps the base of the temporary storage plate 55 and places it onto the product jig 14 on the rotary conveyor tray.

[0075] like Figure 8 As shown, the PIN needle loading station 6 includes: a mobile module D62 arranged above the rotary conveyor disk, a liftable clamp D63 is arranged below the mobile module D62, and a screw loader 61 and a temporary storage component for providing PIN needles are arranged on the outside of the mobile module D62; when working, the PIN needles are poured into the screw loader 61, and the screw loader 61 discharges the materials in sequence.

[0076] The temporary storage assembly includes: temporary storage pipettes 64 for temporarily storing PIN needles. In this embodiment, there are two sets of temporary storage pipettes 64, each suitable for different types of PIN needles. A rotary cylinder D65 controls the rotation of the temporary storage pipettes 64. The rotary cylinder D65 has two positions: a vertical position for loading PIN needles from the screw machine 61, and a horizontal position for inserting PIN needles into the base 103 of the rotary conveyor tray product fixture. A propulsion cylinder D67 is provided on the side of the rotary cylinder D65 away from the rotary conveyor tray 13 to propel the rotary cylinder D65 longitudinally. Below the propulsion cylinder D67, a transverse movement module D66 is provided to drive the propulsion cylinder D67 transversely. The transverse movement module D66 is used to select the appropriate position to align with the product fixture when different types of PIN needles are being loaded.

[0077] The working principle of the PIN needle loading station is as follows: the screw loader 61 loads the PIN needle, the mobile module D62 drives the clamp D63 to pick up the PIN needle and place it into the temporary storage straw 64, and the PIN needle is adsorbed by vacuum pressure. The rotating cylinder D65 drives the temporary storage straw 64 to rotate 90 degrees so that it is aligned with the product in the product fixture. The propulsion cylinder D67 pushes the rotating cylinder D65 to move to the side close to the product fixture, thereby sending the PIN needle into the PIN pin hole 106 of the product in the product fixture, completing the PIN needle loading and assembly.

[0078] Furthermore, when the PIN is inserted into the PIN hole 106 , a pressing mechanism can temporarily press the decorative ring to prevent the decorative ring from shifting during assembly of the PIN, which could result in the PIN being unable to be assembled or being offset.

[0079] When the product and PIN needle model change, the PIN needle is sent to another set of temporary storage straws. In order to make the temporary storage straws 64 align with the position of the PIN needle holes when the PIN needles are loaded, the position of the temporary storage components can be adjusted by the transverse module D66.

[0080] like Figure 9-11As shown, the shrapnel loading station 7 includes: a vibrating plate 71, a straight material channel 72 connected to the vibrating plate 71, a positioning assembly 75 arranged at the end of the straight material channel 72 away from the vibrating plate 71, and a moving module E73 and a clamping claw E74 are arranged between the positioning assembly 75 and the rotary conveyor plate 13. The clamping claw E74 is arranged at the moving module E73 through a lifting mechanism. The lifting mechanism here can be a cylinder.

[0081] The positioning assembly 75 includes a lifting block E751 disposed at the terminal end of the straight material channel 72 for carrying the spring piece 104. The lifting block E751 is driven up and down by a lifting cylinder below it. A horizontally movable push plate E752 is disposed above the lifting block E751. A slot 753 is defined at one end of the push plate E752. The lifting block E751 can carry the spring piece 104 through the slot 753. The slot 753 has two storage positions for two spring pieces 104. After the first spring piece 104 is driven through the slot 753 by the lifting block E751, the pushing cylinder E754 pushes the push plate E752 to move the first spring piece forward into the first storage position. The push plate E752 resets, and the lifting block E751 then delivers the second spring piece to the second storage position. The positions of the two storage positions are set to match the positions of the two spring pieces in the product.

[0082] The movable module E73 is provided with a lifting claw E74, which has two clamping positions corresponding to two springs respectively, and a pressing cylinder E742 and a pressing block E743 (such as Figure 11 As shown), when the spring piece is installed in the base, the pressing block E743 can be pushed by the pressing cylinder E742 to press the base to prevent the base 103 from moving during the assembly of the spring piece, thereby affecting the assembly quality of the spring piece.

[0083] like Figure 13 As shown, the counterweight loading station 8 includes: a pressing mechanism 85 arranged above the rotary conveyor plate, a counterweight loading mechanism 84 arranged outside the pressing mechanism 85, and a receiving machine arranged on the side of the counterweight loading mechanism 84 away from the pressing mechanism 85.

[0084] A feeding channel 83 is provided on the outside of the material receiving mechanism, and a first feeding mechanism 81 and a second feeding mechanism 82 with the same structure are symmetrically provided on both sides of the feeding channel 83;

[0085] like Figure 15 、 16As shown, the first feeding mechanism 81 and the second feeding mechanism 82 are respectively provided with: a storage box 811, the bottom of the storage box 811 gradually lowers from the outside to the side close to the loading channel 83, and a discharge port 8111 is provided on the bottom side of the storage box 811. Due to the inclined setting of the storage box 811, after the lowest counterweight block is discharged through the discharge port 8111, the subsequent counterweight blocks can fall freely to the discharge port position by gravity. A feeding channel 812 is provided in close proximity to the outside of the discharge port 8111. A suction mechanism 813 for sucking material from the discharge port is provided on the side of the feeding channel 812 away from the discharge port. The suction mechanism 813 comprises a magnet 8134, a suction cylinder 8131 for driving the magnet 8134, and a suction guide rail 8132 and a suction slider 8133 below the magnet 8134. The magnet 8134 can be driven by the suction cylinder 8131 to reach the discharge port 8111 and suck out the lowest set of counterweights in the storage box 811. A pressing cylinder F814 and a pressing block F815 on the outside of the storage box 811 can temporarily hold down the counterweights sucked out by the magnet 8134. When material feeding is required, the pressing block F815 is released, and since the feeding channel 812 is also higher at one end than at the other, the counterweights 105 will slide down due to gravity.

[0086] like Figure 14 As shown, the lowest ends of the first feeding mechanism 81 and the second feeding mechanism 82 meet above the feeding channel 83, as shown in FIG. Figure 17 As shown, the lowest ends of the first and second feeding mechanisms 81, 82 are respectively provided with a limit rod 8161 and a limit cylinder 816 that drives the limit rod 8161. The two feeding mechanisms operate alternately. While one feeding mechanism is feeding, the other feeds refills. The limit rod of the refilling feeding mechanism rises to block the feeding channel on the other side. The use of two feeding mechanisms enables uninterrupted feeding without stopping the machine, improving the loading efficiency of the counterweight.

[0087] like Figure 14 、 Figure 18 As shown, at one end of the feeding channel 83 close to the first feeding mechanism 81 and the second feeding mechanism 82, there are provided a feeding push block F832 for pushing the counterweight block from the feeding channel into the feeding channel and a feeding cylinder F831 for driving the feeding push block F832 to move; the feeding channel 83 has a certain length and can accommodate multiple counterweight blocks at the same time.

[0088] like Figure 14As shown, a material receiving mechanism is provided on one side of the feeding channel 83 close to the counterweight feeding mechanism 84, and the material receiving mechanism includes: a material receiving jig 861, a material receiving lifting cylinder 86 for driving the material receiving jig 861 to rise and fall, and a material receiving transverse movement cylinder 862 for driving the material receiving jig 861 to move transversely. The material receiving jig 861 is located on the outside of the feeding channel 83 and has two positions for carrying counterweights; when the first counterweight enters the first position, the material receiving transverse movement cylinder 862 moves, and the second counterweight enters the second position. After the counterweights are sent into the two positions, the material receiving lifting cylinder 86 reaches a certain height, which can not only block the subsequent counterweights, but also facilitate the loading of the counterweight feeding mechanism.

[0089] The counterweight loading mechanism 84 includes: a loading lifting cylinder F843 at the bottom, a rotating cylinder F842 arranged at the upper end of the piston rod of the loading lifting cylinder F843, a loading connecting rod 841 provided at the rotating end of the rotating cylinder 842, and suction plates 844 provided at both ends of the loading connecting rod 841. The positions of the two suction plates 844 correspond to the material receiving fixture 861 of the material receiving mechanism and the product fixture 14 on the rotary conveyor disc, respectively. A makeshift hole 8441 with a width shorter than the length of the counterweight is provided in the middle of the suction plate 844, and the suction plate 844 absorbs the counterweight by vacuum adsorption. The operating principle is as follows: After the counterweight 105 is raised by the material receiving mechanism, the feeding lifting cylinder F843 drives the feeding connecting rod 841 downward. The suction plate 844 at one end of the feeding connecting rod 841 draws the counterweight from the material receiving mechanism. Then, the rotating cylinder F842 drives the feeding connecting rod 841 to rotate 180 degrees, delivering the counterweight 105 to the base of the product fixture 14 on the rotary conveyor plate. The pressing mechanism 85 presses the counterweight into the base on the rotary conveyor plate through the clearance hole 8441. The pressing mechanism consists of a pressing rod F852 and a pressing cylinder F851 that drives the pressing rod F852.

[0090] At the rear end of the counterweight loading station 8 and between the assembly station 10, a CCD inspection station 9 is provided to detect whether the spring piece 104, the counterweight 105 and the PIN needle (not marked in the figure) in the base are all installed, and whether the installation position is prepared. After the accurate installation passes through the assembly station 10, the good product unloading station 12 will unload it, and the inaccurate installation will be sent to the defective product unloading station 11.
