[0019] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0020] The embodiment of the present invention relates to an automatic assembly mechanism for an automobile inner door handle spring, such as Figure 1 As shown, it includes a speed line 1 and a control system, the speed line 1 is provided with a positioning tray 2, the positioning tray 2 is fixed with an inner handle body, and the two sides of the speed line 1 are provided with a handle assembly system 3, a spring assembly system 4 and a pin shaft screening installation device 5; the handle assembly system 3, the spring assembly system 4 and the pin shaft screening installation device 5 are all connected to the control system, and the control system controls the handle assembly system 3, the spring assembly system 4 and the pin shaft screening installation device 5 to work in coordination.

[0021] The interior door handle structure targeted by this embodiment is as follows Figure 5 As shown, the inner door handle is assembled from four parts: inner handle body A, handle B, spring C, and pin D. The handle and spring need to be lubricated with grease. The handle and the inner handle body are connected by installing the spring and the pin to realize the opening operation.

[0022] In this embodiment, the handle assembly system 3 includes a handle assembly six-axis robot 31 and an oiling station 32; the handle assembly six-axis robot 31 determines the state and position of the handle through its own visual recognition device, and transports the handle to the oiling station 32 through its own clamp; the oiling station 32 is used to oil the handle; the handle assembly six-axis robot is also used to drive the oiled handle to the assembly station.

[0023] The oiling station 32 comprises an oiling frame 321, a handle placement position 322 is arranged in the middle of the oiling frame 321, and oiling devices 323 are arranged in any three directions of the front, back, left, and right directions of the handle placement position 322; the oiling devices 323 are connected to the oiling pump 324 through a pipeline. The oiling pump 324 is provided with an oil quantity regulating valve.

[0024] When the handle assembly system is working, the handle assembly six-axis robot clamps the handle and moves the handle to the handle placement position in the middle of the oiling rack. The oiling pump sends oil to the three oiling units through pressurization. The three oiling units can work synchronously. In order to ensure the stability of the oiling amount, an oil regulating valve is added to the oil pump to control the oil output. After the oiling is completed, the handle assembly six-axis robot can move the handle to the assembly station for installation.

[0025] In this embodiment, the spring assembly system 4 includes a spring assembly six-axis robot 41 and a spring screening and oiling device 42. The spring screening and oiling device 42 is used to oil the springs, and the spring assembly six-axis robot 41 is used to pre-compress the springs after the oiling operation and then transport them to the assembly station.

[0026] like Figure 3As shown, the spring screening and oiling device 42 includes a spring vibration disk 421 and a spring oiling unit 422. A cylinder 423 is provided on one side of the discharge port of the spring vibration disk 421. The cylinder 423 pushes the spring to the spray port of the spring oiling unit 422. The spring oiling unit 422 is used to oil the spring. When the spring screening and oiling device is used, it is only necessary to manually pour the corresponding springs randomly from the feed port of the spring vibration disk. The spring vibration disk will automatically adjust the posture of the spring through mechanical principles and light sensors. The springs with adjusted posture are queued and output from the discharge port of the spring vibration disk. At this time, the cylinder on one side of the discharge port can push the spring to the spray port of the oiling unit for oiling. In order to ensure the stable operation of the spring vibration disk and not generate noise beyond the normal working environment, the frame part of the spring vibration disk can actively adopt shock absorption and sound insulation measures.

[0027] like Figure 4 As shown, the pin screening and installation device 5 includes a pin vibration disk 51 and an automatic pinning device 52; the automatic pinning device 52 is arranged on one side of the discharge port of the pin vibration disk 51, and drives the pin into the assembly position under the action of the pneumatic pipeline. When the pin screening and installation device is used, it is only necessary to manually pour the corresponding pins randomly from the feed port of the pin vibration disk in a whole package. The pin vibration disk automatically adjusts the posture of the pin through mechanical principles and light sensors. The pins with adjusted postures are queued and output from the discharge port of the pin vibration disk. When the positioning tray moves to the work station, the automatic pinning device located on one side of the discharge port of the pin vibration disk can push the pin through the pneumatic pipeline, thereby driving the pin into the assembly position to achieve the installation of the spring. In order to ensure the stable operation of the pin vibration disk and not generate noise beyond the normal working environment, the vibration disk frame part actively adopts shock absorption and sound insulation measures.

[0028] In this embodiment, the positioning tray used to fix the handle body moves by means of the double-speed line, and the handle assembly system, spring assembly system and pin screening and installation device are distributed on both sides of the double-speed line for coordinated operation. Through the control system, the above-mentioned handle assembly system, spring assembly system and pin screening and installation device are coordinated and cooperated, so that the full automatic assembly of the automobile inner door handle spring can be realized. The key actions of this embodiment replace manual work throughout the process, so that the assembly cycle is increased from the original 60 seconds / piece to 7 seconds / piece, which improves work efficiency, and also reduces the original manual assembly line operators from 6 people to 1 person, which greatly saves manpower. At the same time, the product assembly status can be unified, the finished product shipping status is guaranteed, and the qualified rate is effectively guaranteed. If it is replaced with another type of inner door handle, it is only necessary to replace the clamping tooling of the product and switch the settings of the assembly line to realize the automated assembly of another type of inner door handle.

[0029] like Figure 6As shown, the automatic assembly mechanism of the automobile inner door handle spring of the present embodiment includes the following steps during assembly: the first step: the inner handle body is driven to the assembly station by the double-speed line; the second step is divided into three actions that are performed simultaneously: 2-1. The handle assembly six-axis robot finds the state and position of the handle through its own visual recognition device, grabs the handle through its own clamp and drives it to the oiling station for oiling, and then drives the handle after oiling to the assembly station; 2-2. The spring vibration plate adjusts the posture of the spring and then performs the oiling operation. The spring assembly six-axis robot finds the state and position of the spring through its own visual recognition device, and grabs the spring through the clamp after pre-stressing, and then drives it to the assembly station; 2-3. The pin shaft vibration plate adjusts the posture of the pin shaft and then stands by; the third step: the inner handle body with the assembled handle and spring is driven by the double-speed line to one side of the pin shaft screening and installation device, and the automatic pinning mechanism pushes the adjusted posture into the current through the pneumatic pipeline to complete the spring assembly work.
