Description

Technical Field

[0001] The present invention relates to the technical field of door handle assembly, and in particular to a door handle assembly machine assembly. Background Art

[0002] like Figure 1 As shown, a door handle consists of a base 101 and a handle 102 mounted thereon, an aluminum cover 103 and a spring 104 are arranged between the base 101 and the handle 102, and a steering door gasket 105 is also provided on the side of the base 101 away from the handle 102. When in use, the above parts need to be assembled and fixed together in sequence. The current assembly method requires manual installation of the spring 104, aluminum cover 103, base 101 and steering door gasket 105 one by one into the shaft seat 1021 of the handle 102, and then a rotary riveting sealing machine is used to process a flange around the loading end of the shaft seat 1021 to ensure that the assembled parts will not loosen. If some products need to install an axis hole 106 on the axis seat 1021 of the handle 102, it is necessary to use an additional drilling mechanism to process the axis hole on the axis seat 1021. This traditional assembly method is obviously time-consuming, labor-intensive and inefficient.

[0003] In view of the problems existing in the current assembly methods, improving the efficiency of door handle assembly has always been a challenge that needs to be urgently addressed by technicians in this field. Summary of the Invention

[0008] Specifically, the first vibration feeding device includes a first vibration disk and a first vibration output guide rail. The first vibration disk is fixed on one side of the workbench. The first vibration disk is used to store shrapnel and generate a vibration source. The first vibration output guide rail is arranged on the discharge port of the first vibration disk. The first vibration output guide rail is used to transmit shrapnel through secondary vibration output. The first material separation device is arranged at the transmission end of the first vibration output guide rail. After applying this structure, the design of the first vibration disk and the first vibration output guide rail makes the transmission of shrapnel more stable and efficient. The first vibration disk is a device for storing shrapnel and generating a vibration source, which ensures the continuous supply and vibration transmission of shrapnel. The first vibration output guide rail transmits the shrapnel from the first vibration disk to the first material separation device through secondary vibration output. The first material separation device is used to accurately separate a single shrapnel from the numerous shrapnel transmitted on the first vibration output guide rail. This optimization solution improves the transmission efficiency of shrapnel and reduces the time consumption during the assembly process.

[0009] As an improvement, the first material distributing device includes a driving cylinder horizontally arranged on the workbench, a movable seat fixed at the output end of the driving cylinder, and a material picking jig fixed at the top of the movable seat. The material picking jig can move back and forth horizontally along the transmission direction perpendicular to the first vibration output guide rail. A material distributing port is provided on the side of the material picking jig adjacent to the transmission end of the first vibration output guide rail. The material distributing port is used to receive shrapnel one by one from the transmission end of the first vibration output guide rail. After applying this structure, the driving cylinder drives the movable seat and the material picking jig on the movable seat to move back and forth horizontally along the transmission direction perpendicular to the first vibration output guide rail. The material picking jig uses its material distributing port to receive shrapnel one by one from the transmission end of the first vibration output guide rail, so that the first robotic arm can pick up a single shrapnel from the material distributing port of the material picking jig and assemble it to the handle of the first clamp. The use of this first material distributing device can improve the accuracy and speed of shrapnel material distribution, further reduce the time consumption in the assembly process, and ensure the stability of assembly quality. At the same time, the first material distributing device has the advantages of simple structure and low cost.

[0010] As an improvement, a push cylinder is fixed on the top of the retrieving jig, with the output end of the push cylinder facing one side of the dispensing opening. A pressure block is also fixed to the output end of the push cylinder, which is used to push the spring piece located in the dispensing opening into contact with the other side of the dispensing opening. This structure allows the spring piece to be accurately positioned within the dispensing opening of the retrieving jig, ensuring that the first robotic arm can accurately pick up the spring piece from the dispensing opening of the retrieving jig. This improvement improves the accuracy and speed of the assembly process.

[0011] As an improvement, the first robotic arm includes a translation device, a lifting device and a clamping device. A crossbeam is fixed on the workbench, and the crossbeam is located between the first material distribution device and the first clamp.

The lower end of the elastic member is flat and is used to resist the spring located in the material distribution port. After applying this structure, the coordinated operation of the translation device, the lifting device and the clamping device ensure that the first robotic arm can accurately pick up the shrapnel from the material distribution port of the material picking fixture and load it into the handle located on the first clamp. The picking structure of the gripping claw and the finger cylinder of the clamping device simulates the picking up of shrapnel by human hands, thereby improving the efficiency and accuracy of the picking operation. The lower end of the elastic part has a flat structural design, which can prevent one end of the shrapnel from tilting up when the gripping claw grabs the shrapnel, thereby ensuring that the shrapnel grabbed by the gripping claw can be accurately loaded into the handle. The elasticity of the elastic part itself can provide cache protection for the shrapnel when the elastic part presses down the shrapnel. At the same time, the picking structure effectively solves the problem that the suction cup picking method cannot absorb circular parts.

[0012] Specifically, the base handle assembly and fixing mechanism includes a fourth robotic arm, a rotary riveting sealing machine, and a fixed frame. The fourth robotic arm is used to pick up the aluminum cover, base, and steering door gasket as a whole from the second fixture and install them as a whole onto the handle with the spring clip installed in the first fixture. The rotary riveting sealing machine is used to process an anti-slip structure on the handle shaft seat after the fourth robotic arm completes the assembly operation. The fixed frame and the fourth robotic arm are both set on a workbench and correspond to the position of one of the multiple tooling placement points. The rotary riveting sealing machine is set on the fixed frame. During operation, first, the fourth robotic arm is used to assemble the first assembly unit assembled by the spring clip feeding assembly mechanism and the second assembly unit assembled by the base feeding assembly mechanism and the steering door gasket feeding assembly mechanism as a whole. Then, the rotary riveting sealing machine is used to process a flange around the handle shaft seat. The flange on the handle shaft seat is used to ensure the secure connection of the two assembly units, completing the final door handle product. Through the application of the above structure, the assembly process of the present invention is fully automated, eliminating manual intervention, thereby significantly improving production efficiency and reducing costs.

The punch is configured to machine an axial hole in the handle's shaft seat after the base handle assembly and fixing mechanism completes assembly and fixing operations. The drilling mechanism accommodates the automated assembly of door handles with axial holes, expanding the application scope of the door handle assembly machine assembly.

[0014] As an improvement, the system also includes a bearing loading and assembly mechanism for loading the bearing into the shaft hole of the handle of the first fixture. The bearing loading and assembly mechanism is positioned on the workbench and corresponds to one of the multiple fixture placement points. The bearing loading and assembly mechanism allows for rapid installation of bearings into door handles with shaft holes, significantly improving assembly efficiency compared to manual bearing assembly.

[0015] As an improvement, the system further includes an offline transfer mechanism, which is arranged on a workbench and corresponds to one of the multiple tooling placement points. The offline transfer mechanism includes a sixth robotic arm arranged on the workbench and a conveyor device with one end extending below the sixth robotic arm. The sixth robotic arm is used to pick up the assembled and fixed door handle finished product from the first fixture after the base handle assembly and fixing mechanism completes the assembly and fixing operation and place it on the conveyor device, which is used to transport the door handle finished product. After applying this structure, the sixth robotic arm replaces manual labor in picking up the assembled door handle finished product from the first fixture of the turntable, and the conveyor device simultaneously transports the assembled door handle finished product to another storage location. Compared with manual picking of products from the first fixture of the turntable, this structure has higher picking efficiency and can also prevent local high temperature burns to the human hand caused by the door handle during the riveting operation.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Example 1: Figure 2 and Figure 3As shown, in this embodiment, the door handle assembly machine assembly includes a workbench 1 and a turntable 2 arranged on the workbench 1 and rotating around a fixed axis. A divider is provided under the turntable 2 for controlling the turntable 2 to rotate quantitatively in steps. A plurality of tool placement points are evenly distributed on the circumference of the turntable 2, and the spacing between any two adjacent tool placement points is consistent with the step rotation interval of the turntable 2. Each tool placement point is provided with a first fixture 21 for placing the handle and a second fixture 22 for placing the aluminum cover. The positions corresponding to each tool placement point on the workbench 1 are provided in sequence with a spring feeding assembly mechanism 3, a bottom The seat feeding assembly mechanism 4, the steering door pad feeding assembly mechanism 5 and the base handle assembly and fixing mechanism 6, the spring clip feeding assembly mechanism 3 is used to load the spring clip onto the handle located in the first fixture 21, the base feeding assembly mechanism 4 is used to load the base onto the aluminum cover located in the second fixture 22, the steering door pad feeding assembly mechanism 5 is used to load the steering door pad onto the base located in the second fixture 22, the base handle assembly and fixing mechanism 6 is used to load the aluminum cover, base and steering door pad located on the second fixture 22 as a whole onto the handle located in the first fixture 21 that has been loaded with the spring clip and to machine an anti-slip structure on the axle seat of the handle.

[0037] Compared with the prior art, the present invention is beneficial in that: the present invention provides a first fixture 21 and a second fixture 22 on the turntable 2 for placing the handle and the aluminum cover of the door handle respectively, and then, the spring clip is loaded onto the handle located on the first fixture 21 by the spring clip feeding assembly mechanism 3 to complete the assembly operation of the first assembly unit, and the base and the steering door pad are sequentially loaded into the aluminum cover located on the second fixture 22 by the base feeding assembly mechanism 4 and the steering door pad feeding assembly mechanism 5 to complete the assembly operation of the second assembly unit, and finally, the two assembly units are assembled as a whole and fixed by the base handle assembly fixing mechanism 6 to form a finished door handle product. The present invention replaces the manual assembly of the door handle in the prior art by mechanical operation. The operation form of assembling parts one by one realizes a fast, efficient and automated assembly process, significantly reduces manpower input and assembly time, and improves production efficiency. It has been calculated that with manual assembly, a skilled worker can complete the assembly of 50 door handle products in one hour, while the present invention only requires one person to complete the placement of handles and aluminum covers into the first fixture 21 and the second fixture 22, and other operations are completed automatically. The assembly of 420 door handle products can be completed in one hour, and the operation efficiency is eight times that of the traditional operation method. Moreover, the stability and consistency of the door handle assembly quality of the present invention are better. In addition, a plurality of tooling placement points are set on the turntable 2 of the present invention to ensure that multiple assembly stations can operate simultaneously, with higher assembly efficiency.

[0038] like Figure 4 and Figure 5As shown, the shrapnel loading and assembly mechanism 3 includes a first vibrating feeding device 31, a first dividing device 32 and a first robotic arm 33 fixed on the workbench 1. The first vibrating feeding device 31 is used to store and transmit shrapnel through vibration output. The first dividing device 32 is located at the transmission end of the first vibrating feeding device 31 and is used to separate a single shrapnel from multiple shrapnel transmitted on the first vibrating feeding device 31. The first robotic arm 33 is used to pick up the shrapnel from the first dividing device 32 and load it into the handle located on the first clamp 21. After applying this structure, the introduction of the first vibrating feeding device 31, the first dividing device 32 and the first robotic arm 33 makes the assembly process of the shrapnel more precise and efficient. The first vibrating feeding device 31 solves the problem of storage and automatic transmission of the shrapnel used in the assembly process. Through the separation effect of the first dividing device 32, a single shrapnel can be accurately extracted from the numerous shrapnel transmitted. The use of the first robotic arm 33 realizes the automatic transfer of the shrapnel from the first dividing device 32 to the first fixture 21, and accurately assembles the shrapnel to the handle to complete the assembly operation of the first assembly unit. This optimization scheme not only greatly reduces the manpower input in the assembly process and improves the assembly efficiency, but also ensures the accuracy and consistency of the assembly.

[0039] like Figure 5 As shown, the first vibrating feeding device 31 includes a first vibrating disk 311 and a first vibrating output guide rail 312. The first vibrating disk 311 is fixed on one side of the workbench 1. The first vibrating disk 311 is used to store shrapnel and generate a vibration source. The first vibrating output guide rail 312 is arranged on the discharge port of the first vibrating disk 311. The first vibrating output guide rail 312 is used to transmit shrapnel through secondary vibration output. The first dividing device 32 is arranged at the transmission end of the first vibrating output guide rail 312. After applying this structure, the design of the first vibration disk 311 and the first vibration output guide rail 312 makes the transmission of the shrapnel more stable and efficient. The first vibration disk 311 serves as a device for storing shrapnel and generating a vibration source, ensuring the continuous supply and vibration transmission of the shrapnel. The first vibration output guide rail 312 transmits the shrapnel from the first vibration disk 311 to the first material dividing device 32 through secondary vibration output. The first material dividing device 32 is used to accurately separate a single shrapnel from the numerous shrapnel transmitted on the first vibration output guide rail 312. This optimization solution improves the transmission efficiency of the shrapnel and reduces the time consumption during the assembly process.

[0040] like Figure 5As shown, the first material dividing device 32 includes a driving cylinder 321 horizontally arranged on the workbench 1, a movable seat 322 fixed at the output end of the driving cylinder 321, and a material picking fixture 323 fixed on the top of the movable seat 322. The material picking fixture 323 can move back and forth horizontally along the transmission direction perpendicular to the first vibration output guide rail 312. A material dividing port 324 is provided on the side of the material picking fixture 323 adjacent to the transmission end of the first vibration output guide rail 312. The material dividing port 324 is used to receive shrapnel one by one from the transmission end of the first vibration output guide rail 312. After applying this structure, the driving cylinder 321 drives the movable seat 322 and the material picking fixture 323 on the movable seat 322 to move horizontally back and forth along the transmission direction perpendicular to the first vibrating output guide rail 312, and the material picking fixture 323 uses its material distribution port 324 to receive the shrapnel one by one from the transmission end of the first vibrating output guide rail 312, so that the first robotic arm 33 can pick up a single shrapnel from the material distribution port 324 of the material picking fixture 323 and assemble it to the handle of the first clamp 21. The use of this first material distribution device 32 can improve the accuracy and speed of shrapnel distribution, further reduce the time consumption in the assembly process, and ensure the stability of the assembly quality. At the same time, the first material distribution device 32 has the advantages of simple structure and low cost.

[0041] like Figure 5 As shown, a push cylinder 325 is fixedly installed on the top of the material picking fixture 323. The output end of the push cylinder 325 is arranged toward one side of the material dispensing opening 324. A pressure block 326 is fixedly installed at the output end of the push cylinder 325. The pressure block 326 is used to push the spring piece located in the material dispensing opening 324 to fit and position with the other side of the material dispensing opening 324. The application of this structure enables the spring piece to be accurately positioned and placed in the material dispensing opening 324 of the material picking fixture 323, thereby ensuring that the first robot arm 33 can accurately pick up the spring piece from the material dispensing opening 324 of the material picking fixture 323. This improvement improves the accuracy and speed of the assembly process.

[0042] like Figure 5As shown, the first robotic arm 33 includes a translation device 331, a lifting device 332 and a clamping device 333. A crossbeam 11 is fixed on the workbench 1, and the crossbeam 11 is located between the first material distribution device 32 and the first clamp 21. The translation device 331 can be moved horizontally back and forth and is set on the crossbeam 11. The lifting device 332 can be moved up and down and is set on the translation device 331. The clamping device 333 is set on the lifting device 332. The clamping device 333 includes a pair of claws 3331 and a finger cylinder 3332 for driving the pair of claws 3331 to open and close. An elastic member 3333 is provided between the pair of claws 3331. The upper end of the elastic member 3333 is fixedly connected to the body of the finger cylinder 3332. The lower end of the elastic member 3333 is flat and is used to resist the spring located in the distribution port 324. After applying this structure, the coordinated operation of the translation device 331, the lifting device 332 and the clamping device 333 ensures that the first robotic arm 33 can accurately pick up the shrapnel from the material distribution port 324 of the material picking fixture 323 and load it into the handle located on the first clamp 21. The picking structure of the claw 3331 and the finger cylinder 3332 of the clamping device 333 simulates the picking up of shrapnel by human hands, thereby improving the efficiency and accuracy of the picking operation. The lower end of the elastic member 3333 is a flat structural design, which can prevent one end of the shrapnel from tilting when the claw 3331 grabs the shrapnel, thereby ensuring that the shrapnel grabbed by the claw 3331 can be accurately loaded into the handle. The elasticity of the elastic member 3333 itself can provide cache protection for the shrapnel when the elastic member 3333 presses down the shrapnel. At the same time, this picking structure effectively solves the problem that the suction cup picking method cannot absorb circular parts.

[0043] like Figure 6 and 7 As shown, the base loading and assembly mechanism 4 includes a second vibrating feeding device 41 fixed to the workbench 1, a second material separation device 42, and a second robotic arm 43. The second vibrating feeding device 41 includes a second vibrating plate 411 and a second vibrating output guide rail 412. The second vibrating feeding device 41 is used to store and transmit the base through the vibration output. The second material separation device 42 is located at the transmission end of the second vibrating feeding device 41 and is used to separate a single base from the multiple bases transmitted by the second vibrating feeding device 41. The second robotic arm 43 is used to pick up the base from the second material separation device 42 and load it onto the aluminum cover located on the second fixture 22. After applying this structure, the base can be accurately assembled to the aluminum cover, completing automated assembly, reducing labor input, and improving work efficiency.

[0044] like Figure 8 and 9As shown, the steering doormat loading and assembly mechanism 5 includes a third vibrating feeding device 51 fixed to the workbench 1, a third material dividing device 52, and a third robotic arm 53. The third vibrating feeding device 51 includes a third vibrating plate 511 and a third vibrating output guide rail 512. The third vibrating feeding device 51 is used to store and transmit the steering doormat through vibration output. The third material dividing device 52 is located at the transmission end of the third vibrating feeding device 51 and is used to separate a single steering doormat from multiple steering doormats transmitted by the third vibrating feeding device 51. The third robotic arm 53 is used to pick up the steering doormat from the third material dividing device 52 and load it onto the base located on the second fixture 22. After applying this structure, the steering doormat can be accurately assembled to the base, completing automated assembly, reducing labor input, and improving work efficiency.

[0045] like Figure 10 and Figure 11 As shown, the base handle assembly and fixing mechanism 6 includes a fourth robotic arm 61, a rivet sealing machine 62, and a fixing frame 12. The fourth robotic arm 61 is used to pick up the aluminum cover, base, and steering door gasket from the second fixture 22 as a whole and install them onto the handle with the spring clip installed in the first fixture 21. The rivet sealing machine 62 is used to process an anti-slip structure on the handle shaft seat after the fourth robotic arm 61 completes the assembly operation. The fixing frame 12 and the fourth robotic arm 61 are both located on the workbench 1 and correspond to one of the multiple tooling placement points. The rivet sealing machine 62 is located on the fixing frame 12. During operation, the fourth robotic arm 61 first assembles the first assembly unit assembled by the spring clip feeding assembly mechanism 3 and the second assembly unit assembled by the base feeding assembly mechanism 4 and the steering door gasket feeding assembly mechanism 5 as a whole. Then, the rivet sealing machine 62 processes a flange around the handle shaft seat. The flange on the handle shaft seat ensures a secure connection between the two assembly units, completing the final door handle product. By applying the above structure, the assembly process of the present invention is fully automated, eliminating manual intervention, thereby significantly improving production efficiency and reducing costs. In this structure, the structure and function of the fourth robotic arm 61 are the same as those of the first robotic arm 33, and the two can also adopt different structures.

[0046] In the present invention, in order to improve assembly efficiency and ensure accurate loading of spare parts, the base loading assembly mechanism 4, the steering door pad loading assembly mechanism 5 and the shrapnel loading assembly mechanism 3 adopt similar design concepts, all of which include a first vibrating feeding device 31, a first material dividing device 32 and a robotic arm. The first vibrating feeding device 31, as the core part of these assembly mechanisms, is composed of a carefully designed first vibration plate 311 and a first vibration output guide rail 312 to achieve efficient conveying of parts. According to the different characteristics of parts, the internal structure of the first vibration plate 311 of each mechanism has been specially adaptively designed to meet their respective assembly requirements and ensure that the parts can be sorted and transported to the assembly point in the best condition. This innovative design takes into account the differences in part shape, size and weight, and completes the personalized customization of the first vibration plate 311, thereby optimizing the efficiency and accuracy of the entire loading process.

[0047] When using the present invention to assemble a door handle, the steps are as follows:

[0048] Step 1: An operator manually places the handle into the first fixture 21 and the aluminum cover into the second fixture 22. After the first fixture 21 and the second fixture 22 are respectively placed in the handle and the aluminum cover, the turntable 2 is rotated at intervals and transferred to the assembly station of the spring feeding assembly mechanism 3;

[0049] Step 2: At the assembly station of the shrapnel feeding assembly mechanism 3, the first vibrating feeding device 31, the first material dividing device 32 and the first robotic arm 33 work in coordination to complete the conveying, picking up and assembly of the shrapnel. The shrapnel stored in the first vibrating plate 311 is loaded onto the handle of the first fixture 21 to complete the assembly operation of the first assembly unit. After the assembly operation of the first assembly unit is completed, the turntable 2 is rotated at intervals to transfer the shrapnel to the assembly station of the base feeding assembly mechanism 4.

[0050] Step 3: At the assembly station of the base loading assembly mechanism 4, the base is mounted on the aluminum cover on the second fixture 22 by the base loading assembly mechanism 4 in the same manner as the spring sheet loading assembly mechanism 3. After the aluminum cover on the second fixture 22 is mounted on the base, the turntable 2 is rotated at intervals to the assembly station of the doormat loading assembly mechanism 5.

[0051] Step 4: At the assembly station of the steering doormat loading and assembly mechanism 5, the steering doormat is installed on the base located on the second fixture 22 by the steering doormat loading and assembly mechanism 5 in the same operating manner as the spring sheet loading and assembly mechanism 3. At this time, the aluminum cover, base and steering doormat have been installed on the second fixture 22 from bottom to top, thereby completing the assembly operation of the second assembly unit. After the assembly operation of the second assembly unit is completed, the turntable 2 is rotated at intervals to enter the assembly station of the base handle assembly and fixing mechanism 6;

[0052] Step 5: At the assembly station of the base handle assembly fixing mechanism 6, the fourth robotic arm 61 picks up the second assembly unit as a whole from the second fixture 22 and places the second assembly unit as a whole into the first fixture 21 for assembly with the first assembly unit. After the first and second assembly units are assembled, the turntable 2 rotates at intervals and transfers them to the fixing station of the base handle assembly fixing mechanism 6.

[0053] Step 6: At the fixed station of the base handle assembly fixing mechanism 6, a flange is processed around the handle shaft seat by a rotary riveting sealing machine 62. The flange on the handle shaft seat is used to ensure the firm connection of the two assembly units, completing the final door handle product.

[0054] After the finished door handle is manufactured, it can be picked up on the first fixture 21 manually or mechanically.

[0055] In this embodiment, since there are multiple tooling placement points equidistantly distributed on the circumference of the turntable 2, each tooling placement point is provided with a first clamp 21 for placing the handle and a second clamp 22 for placing the aluminum cover, thereby ensuring that in the production process of the above-mentioned door handle finished product, when the subsequent operation steps are carried out, all the operation steps before the operation step can be carried out synchronously, which greatly improves the production efficiency of the door handle and is conducive to the large-scale and mechanized production of door handles. Compared with the inefficient operation method of manually assembling door handles individually in the prior art, the present invention has a qualitative improvement in operation efficiency.

[0056] Example 2: Based on Example 1, this example differs from Example 1 in that:

[0057] like Figure 12 and Figure 13 As shown, the door handle assembly machine assembly further includes a drilling mechanism 7, which is positioned on the workbench 1 and corresponds to one of the multiple tooling placement points. The drilling mechanism 7 includes a mounting frame 71 fixed to the workbench 1 and a punch 72 mounted on the mounting frame 71. The punch 72 is used to machine an axial hole in the handle's shaft seat after the base handle assembly and fixing mechanism 6 completes the assembly and fixing operation. The provision of the drilling mechanism 7 adapts to the needs of automated assembly of door handles with axial holes, expanding the application range of the door handle assembly machine assembly.

[0058] like Figure 14 and Figure 15As shown, the door handle assembly machine assembly also includes a bearing loading and assembly mechanism 8 for loading a bearing into the handle's axial hole located in the first fixture 21. This mechanism is positioned on the workbench 1 and corresponds to one of the multiple fixture placement points. This mechanism allows for rapid installation of bearings into door handles with axial holes, significantly improving assembly efficiency compared to manual bearing assembly.

[0059] Specifically, the bearing feeding and assembly mechanism 8 includes a fourth vibrating feeding device 81 fixed to the workbench 1, a fourth material separation device 82, and a fifth robotic arm 83. The fourth vibrating feeding device 81 includes a fourth vibrating plate 811 and a fourth vibrating output guide rail 812. The fourth vibrating feeding device 81 is used to store and transmit bearings through vibration output. The fourth material separation device 82 is located at the transmission end of the fourth vibrating feeding device 81 and is used to separate a single bearing from the multiple bearings transmitted by the fourth vibrating feeding device 81. The fifth robotic arm 83 is used to pick up the bearing from the fourth material separation device 82 and install it into the shaft hole of the handle located in the first fixture 21. After applying this structure, the bearing can be accurately assembled into the shaft hole of the handle, completing automated assembly, reducing labor input, and improving work efficiency.

[0060] Example 3: Based on Example 1 or Example 2, this embodiment differs from Example 1 or Example 2 in that:

[0061] like Figure 16 and Figure 17 As shown, the door handle assembly machine assembly further includes an offline transfer mechanism 9, which is positioned on the workbench 1 and corresponds to one of the multiple tooling placement points. The offline transfer mechanism 9 includes a sixth robotic arm 91 positioned on the workbench 1 and a conveyor 92 with one end extending below the sixth robotic arm 91. The sixth robotic arm 91 is used to pick up the finished door handle from the first fixture 21 after the base handle assembly and fixation mechanism 6 completes the assembly and fixation operation, or after the bearing loading and assembly mechanism 8 installs the bearing into the handle shaft hole, and place it on the conveyor 92. The conveyor 92 is used to transport the finished door handle. With this structure, the sixth robotic arm 91 replaces manual labor in picking up the assembled door handle from the first fixture 21 of the turntable 2. The conveyor 92 also transports the assembled door handle to another storage location. Compared to manual picking from the first fixture 21 of the turntable 2, this structure achieves higher picking efficiency and also prevents burns to the hands caused by localized high temperatures generated during the riveting operation.

[0062] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present invention.
