[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Please see Figures 1-6 The diagram shows an automated assembly device for plastic handles, comprising a housing 1. The housing 1 is equipped with a receiving device 2, two feeding devices 4, a rotating device 5, a fixing fixture 6, a pressing device 7, and a discharging device 3.

[0032] The receiving device 2 is used to store assembled plastic handles. It includes two sets of support bases 201, each with a third linear guide pair 202. A base plate 203 is mounted on the slider of each of the two third linear guide pairs 202. A storage box 204 for placing the assembled handles is mounted on the base plate 203. A transmission screw pair 205 and a rotary motor 206 for driving the transmission screw pair 205 are also located between the two sets of support bases 201. The screw nut seat of the transmission screw pair 205 is inherently connected to the lower end face of the base plate 203. The shaft of the rotary motor 206 is connected to the screw of the transmission screw pair 205 via a coupling. During operation, the rotary motor 206 drives the transmission screw pair 205 to rotate, causing the screw nut seat to move, which in turn causes the base plate 203 to slide on the third linear guide pairs 202, thus adjusting the position of the storage box 204 for convenient storage of the assembled plastic handles.

[0033] Two feeding devices 4 are used to grip the plastic handle housing and handle, respectively, and place the handle and housing into the fixed fixture 6 in sequence. The feeding device 4 includes a horizontal articulated robot 401. Each horizontal articulated robot 401 has a feeding gripper cylinder 402 at its output end. Each feeding gripper cylinder 402 is connected to the horizontal articulated robot 401 via a lifting cylinder 404. The cylinder body of the lifting cylinder 404 is connected to the output end of the horizontal articulated robot 401, and its extension rod is connected to the cylinder body of the feeding gripper cylinder 402 via a connecting angle iron. Each horizontal articulated robot 401 is mounted on the housing 1 via a robot base 403. The horizontal articulated robot 401 is fixed to the housing 1 via the robot base 403 and can move flexibly in a plane. The lifting cylinder 404 controls the lifting and lowering of the feeding gripper cylinder 402, which grips the plastic handle housing and handle, achieving precise feeding.

[0034] The rotating device 5 includes a reducer 502, a rotating disk 503, and a drive motor 501. The drive motor 501 is housed within the housing 1, and its shaft is connected to the input shaft of the reducer 502 via a synchronous belt and pulley. The rotating disk 503 is connected to the output shaft of the reducer 502. The drive motor 501 transmits power to the reducer 502 via the synchronous belt and pulley. The reducer 502 reduces the rotational speed and increases the torque, thereby rotating the rotating disk 503 and enabling the fixed fixture 6 to change position, allowing the plastic handle to move between different workstations. Multiple fixed fixtures 6 are arranged in a circular array on the upper surface of the rotating disk 503. The fixture 6 has a rectangular shape and features a first limiting groove 10 shaped according to the grip of the plastic handle and a second limiting groove 8 shaped according to the shell of the plastic handle. The first limiting groove 10 and the second limiting groove 8 are interconnected. The fixture 6 also has a third groove 9, which is rectangular and also interconnects with the second limiting groove 8, facilitating the removal of the assembled plastic handle by the feeding gripper cylinder 402. The fixture 6 precisely positions the grip and shell of the plastic handle using the first limiting groove 10 and the second limiting groove 8, ensuring assembly accuracy.

The slider of the first linear guide pair 703 is connected to the side of the column 701, and its guide rail is connected to the side of the horizontal plate 702. The side of the vertical plate 706 is inherently connected to one end of the horizontal plate 702. The second linear guide pair 704 is vertically arranged on the vertical plate 706, and its slider is inherently connected to the connecting plate 708. The cylinder body of the horizontal cylinder 705 is connected to the column 701, and its telescopic rod is connected to the side of the vertical plate 706. The cylinder body of the vertical cylinder 707 is inherently connected to the upper surface of the vertical plate 706, and its telescopic rod is connected to the connecting plate 708. The cylinder body of the double-rod cylinder 709 is inherently connected to the connecting plate 708, and its telescopic rod is inherently connected to the fixing pressure member 710. The electric screwdriver 711 is inherently connected to the connecting plate 708 and is located on one side of the double-rod cylinder 709. A horizontal cylinder 705 drives a horizontal plate 702 to move laterally via a first linear guide pair 703, while a vertical cylinder 707 drives a connecting plate 708 to move vertically via a second linear guide pair 704. A double-rod cylinder 709 drives a fixing member 710 to press the handle and the housing together. An electric screwdriver 711 tightens the screws at the connection points, completing the assembly. The lower end of the fixing member 710 has a fixing cover 712 with a rectangular opening for securing the plastic handle housing, further improving assembly stability.

[0036] The unloading device 3 is located on one side of the receiving device 2 to move the assembled handle into the receiving device 2. It includes a set of symmetrically arranged support columns 301, a transverse plate 302 inherently connected to the two support columns 301, a fourth linear guide pair 303 disposed on the transverse plate 302, a transverse plate 304 connected to a slider on the fourth linear guide pair 303, a fifth linear guide pair 305 disposed on the transverse plate 304, a vertical plate 306 connected to a slider on the fifth linear guide pair 305, a picking gripper cylinder 307 inherently connected to the vertical plate 306, and a picking cylinder 308 that drives the vertical plate 306 to move up and down. The cylinder body of the picking cylinder 308 is inherently connected to the transverse plate 304, and its telescopic rod is connected to the vertical plate 306. Between the two fourth linear guide pairs 303, there is also a second transmission screw pair 309 connected to the transverse plate 302 and a second rotary motor 310 that drives the screw assembly on the second transmission screw pair 309. The screw nut seat on the second transmission screw pair 309 is connected to the transverse plate 304. The second rotary motor 310 drives the second transmission screw pair 309 to move the transverse plate 304 laterally on the fourth linear guide pair 303, the picking cylinder 308 drives the vertical plate 306 to move vertically on the fifth linear guide pair 305, and the picking gripper cylinder 307 picks up the assembled plastic handle and moves it into the storage box 204 of the receiving device 2.

[0037] Working principle:

[0038] The equipment is started, and the horizontal articulated robots 401 in the two feeding devices 4 move on the chassis 1 via the robot base 403, moving the feeding gripper cylinder 402 to the storage position on the external conveying plastic handle housing and gripper device. The lifting cylinder 404 descends, causing the feeding gripper cylinder 402 to grasp the plastic handle housing and gripper. Then the lifting cylinder 404 rises, and the two horizontal articulated robots 401 place the grasped gripper and housing into the limiting groove 10 and the limiting groove 8 of the fixed fixture 6 in sequence.

[0039] The drive motor 501 of the rotating device 5 starts, and drives the reducer 502 to work through the synchronous belt and synchronous pulley. The reducer 502 drives the rotating disk 503 to rotate, so that the fixed fixture 6 with plastic handle housing and grip rotates to the station below the pressing device 7, realizing the flow and precise positioning of the plastic handle between different stations.

[0040] The horizontal cylinder 705 of the pressing device 7 operates, driving the horizontal plate 702 to move laterally via the first linear guide pair 703, so that the fixing component 710 and the electric screwdriver 711 are moved to a suitable position above the fixing fixture 6. The vertical cylinder 707 is activated, driving the connecting plate 708 to descend vertically via the second linear guide pair 704, so that the fixing cover 712 of the fixing component 710 covers the housing of the plastic handle. The double-rod cylinder 709 drives the fixing component 710 to press the handle and the housing together, while the electric screwdriver 711 tightens the screws at the connection, completing the assembly of the plastic handle.

[0041] The second rotary motor 310 of the unloading device 3 drives the second transmission screw pair 309, causing the transverse plate 304 to move laterally on the fourth linear guide pair 303 to a position above the fixed fixture 6. The picking cylinder 308 drives the vertical plate 306 to descend on the fifth linear guide pair 305, and the picking gripper cylinder 307 grabs the assembled plastic handle. Then, the picking cylinder 308 rises, and the second rotary motor 310 drives the second transmission screw pair 309 again, moving the picking gripper cylinder 307 above the receiving box 204 of the receiving device 2. The picking cylinder 308 descends, placing the plastic handle into the receiving box 204. The rotary motor 206 of the receiving device 2 drives the transmission screw pair 205, causing the bottom support plate 203 to slide on the third linear guide pair 202. When the receiving box 204 is full, it can be removed and replaced with a new one to continue storing the assembled plastic handles.
