Detailed Implementation

[0031] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of this utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0032] See Figure 1 , Figure 2 The diagram shows a fully automatic bolt fastening device for assembling and tightening bolts 100 into mounting holes of a product (not shown). It includes a bolt feeding mechanism 201 for supplying the bolts 100, and an oiling mechanism 8 for applying oil to the surface of the bolts 100. See also... Figure 7 , Figure 8As shown, the oiling mechanism 8 includes a fixing member 81, a first rotating seat 82 and a second rotating seat 83 disposed on opposite sides of the fixing member 81 along a first direction. The fixing member 81 has a first state of fixing the bolt 100 and a second state of releasing the bolt 100. The first rotating seat 82 and the second rotating seat 83 can be disposed relatively far apart and relatively close together along the first direction, and the first rotating seat 82 and the second rotating seat 83 are respectively rotatable about a rotation center line extending along the first direction. A clamping space for clamping the bolt 100 is formed between the first rotating seat 82 and the second rotating seat 83. The oiling mechanism also includes an oiling component 84 for applying oil, which is disposed perpendicular to the first direction on one side of the clamping space.

[0033] In this embodiment, the bolt fastening device includes a tightening mechanism 7, which drives the bolt 100 inserted in the mounting hole to rotate, thereby fastening the product. The tightening mechanism 7 includes a fastener 71, which is capable of moving up and down and rotatably arranged about a rotation center line extending in the up and down direction. The fastener 71 is provided with a fixing structure for fixing to the end of the bolt 100. The fastening device also includes a picking member 33 and a feeding member 32 for transporting the bolt 100. The picking member 33 reciprocates between the bolt feeding mechanism 201 and the oiling mechanism 8, and the feeding member 32 reciprocates between the oiling mechanism 8 and the tightening mechanism 7.

[0034] In this embodiment, the material-picking component 33 picks up the bolt 100 from the bolt feeding mechanism 201 and transfers the bolt to the fixing component 81. The fixing component 81 first switches to a first state to receive the bolt 100, and then the first rotating seat 82 and the second rotating seat 83 on both sides move closer together to clamp and fix the bolt 100. At this time, the fixing component switches to a second state and releases the bolt 100. The bolt 100 is rotated by the first rotating seat 82 and the second rotating seat 83, and oil is applied to the bolt 100 by the oiling component 84 on one side. The oiling operation can be automated, saving labor costs and improving efficiency. After the bolt 100 is oiled, the loading component 32 can directly transfer the bolt 100 to the tightening mechanism 7. The loading component 32 can assemble the bolt 100 into the mounting hole of the product and can achieve rotational fixation of the bolt by the fastener 71. The fastening equipment can automate the entire process of picking up, oiling, assembling and tightening the bolt 100. The equipment has a compact production cycle and high processing efficiency.

[0035] In this embodiment, the oiling mechanism 8 includes a first movable frame 85 and a second movable frame 86 that can move closer to each other along a first direction. A first rotating seat 82 and a second rotating seat 83 are respectively rotatably mounted on the first movable frame 85 and the second movable frame 86 about a rotation center line. By driving the first movable frame 85 and the second movable frame 86 to move, the first rotating seat 82 and the second rotating seat 83 can be driven to move relative to each other. In this embodiment, the oiling mechanism 8 includes a translation drive mechanism for driving the first movable frame 85 and the second movable frame 86 to move relative to each other, and the oiling mechanism 8 also includes a rotation drive mechanism for driving the first rotating seat 82 to rotate about a rotation center line.

[0036] In this embodiment, see Figure 7 As shown, the fastener 81 includes two jaws 811 that are able to approach each other perpendicular to a first direction to clamp the bolt 100. In this embodiment, the first direction extends horizontally. When the fastener 81 is in a first state, the two jaws 811 approach each other to clamp the bolt, and when the fastener 81 is in a second state, the two jaws 811 move away from each other.

[0037] In some embodiments, the oiling components 84 include a plurality of components spaced apart along a first direction, and the oiling components 84 are movably arranged along the first direction. By providing multiple oiling components 84, multiple locations on the bolt 100 can be oiled simultaneously, and the positions of the oiling components 84 are adjustable, allowing the oiling position to be adjusted according to different needs. In this embodiment, the oiling mechanism 8 is provided with two oiling components 84, and the two oiling components 84 are movably arranged along the first direction, with the two oiling components 84 respectively applying oil to both ends of the bolt 100.

[0038] In this embodiment, an oil collection box 87 for recycling oil is provided below the clamping space to achieve oil recycling. In this embodiment, two oiling parts 84 are respectively disposed on both sides of the fixing member 81 along the first direction, and two oil collection boxes 87 are provided below the clamping space, which are respectively disposed on both sides of the fixing member 81 along the first direction.

[0039] In this embodiment, the oiling component 84 is an oiling spray gun, with the oil outlet facing the clamping space. The bolt 100 is treated using a spraying method, resulting in better uniformity. In this embodiment, both the oil output and spray pressure of the oiling spray gun can be adjusted to further improve the oiling effect.

[0040] In this embodiment, see Figure 6As shown, the fastener 71 extends vertically and can move up and down to approach or move away from the bolt 100 located below. The fastener 71 can rotate around its own axis to drive the bolt 100 to rotate. The axis of the fastener 71 is the aforementioned rotation center line. In this embodiment, the fixing structure includes a fixing groove provided at the lower part of the fastener 71, which drives the fastener 71 to move downward and allows the end of the bolt 100 to be inserted into the fixing groove to achieve fixing of the two.

[0041] In this embodiment, the product has multiple mounting holes along the axial direction, and a rotating seat 4 for driving the product to rotate is provided below the fastener 71. Specifically, the rotating seat 4 is rotatably arranged about a vertically extending axis of rotation, and the rotating seat 4 has a support surface for supporting the product. The rotating seat 4 simplifies the working procedure of the fastener 71. When the product is supported on the support surface of the rotating seat 4, by driving the rotating seat 4 to rotate, the bolt 100 moves to the bottom of the fastener 71, and the fastener 71 only needs to move downwards to drive the bolt 100 below to rotate and tighten.

[0042] In this embodiment, an assembly position is provided above the rotating base 4, and the assembly position is located on one side of the fastener 71. The loading component 32 reciprocates between the oiling mechanism 8 and the assembly position. By setting the rotating base 4, the working procedure of the loading component 32 is also simplified. The loading component 32 only needs to perform a fixed pattern, transporting the oiled bolt 100 to the assembly position and inserting the bolt 100 into the mounting hole. At the same time, the assembly position is located on one side of the fastener 71, so that the assembly and tightening operations of the bolt 100 do not interfere with each other and can be carried out synchronously, thereby improving efficiency.

[0043] In this embodiment, the bolt fastening equipment further includes a gasket feeding mechanism 202 for providing gaskets and an assembly 31 for assembling gaskets. The bolt fastening equipment also includes an auxiliary tooling 1 and a conveying device 2. The auxiliary tooling 1 has a positioning structure for cooperating with the product and achieving mutual positioning between the two. The conveying device 2 includes a conveying component 21 for assembling the auxiliary tooling 1 onto the product. The auxiliary tooling 1 is assembled onto the product by the conveying component 21, and the positioning structure positions the auxiliary tooling 1 relative to the product, thus fixing the auxiliary tooling 1 relative to the product. The auxiliary tooling 1 has a through-hole 111 capable of accommodating a gasket; when the auxiliary tooling 1 is assembled onto the product, the positioning hole 111 communicates with the mounting hole.

[0044] In this embodiment, the assembly part 31 is used to assemble the gasket into the positioning hole, and the feeding part 32 is used to insert the bolt 100 into the mounting hole from the positioning hole 111. The auxiliary tooling 1 serves as an intermediary between the product and the gasket. After the auxiliary tooling 1 is assembled onto the product, the gasket is then assembled into the positioning hole 111, enabling the gasket to be positioned and fixed relative to the product, thus preventing displacement of the gasket due to disturbance. Subsequently, during the assembly of the bolt 100, the positioning hole 111 also plays a certain guiding role.

[0045] Preferably, the diameter of the positioning hole 111 is slightly larger than the diameter of the gasket, which ensures that the gasket can be easily inserted into the positioning hole 111 while limiting the movable range of the gasket within the positioning hole 111 and preventing the gasket from blocking the mounting hole.

[0046] In this embodiment, the product has multiple mounting holes spaced apart circumferentially, and the auxiliary tooling 1 includes multiple positioning holes 111 spaced apart circumferentially. When the auxiliary tooling 1 is assembled on the product, the multiple positioning holes 111 correspond to and communicate with the multiple mounting holes respectively. In some embodiments, the bolt fastening device has a gasket assembly station 300 for assembling gaskets. The gasket assembly station 300 has a rotating seat 4 that can rotate about a vertically extending axis of rotation. The rotating seat 4 has a support surface for supporting the product. The rotating seat 4 simplifies the working procedure of the assembly part 31. When the product is located at the gasket assembly station 300 and supported on the support surface of the rotating seat 4, by driving the rotating seat 4 to rotate and cooperating with the assembly part 31, the gasket can be easily assembled into the multiple positioning holes 111.

[0047] In some embodiments, the bolt fastening device includes a bolt assembly station 400 for assembling bolts 100. The bolt assembly station 400 is equipped with a rotating seat 4 capable of rotating about a vertically extending axis of rotation. The rotating seat 4 has a support surface for supporting the product. When the product is located at the bolt assembly station 400 and supported on the support surface of the rotating seat 4, by driving the rotating seat 4 to rotate and engaging the mounting part 32, the bolts 100 can be easily assembled into multiple mounting holes.

[0048] In this embodiment, see Figure 3 As shown, the bolt fastening equipment includes a conveyor 5 that transports products along the conveying direction. The equipment is equipped with a gasket assembly station 300 for assembling gaskets and a bolt assembly station 400 for assembling bolts 100, which are sequentially arranged along the conveying direction. In this embodiment, the fastener 71 is located above the bolt assembly station 400, and the feeding component 32 reciprocates between the oiling mechanism 8 and the bolt assembly station 400. Specifically, the feeding component 32 reciprocates between the oiling mechanism 8 and the assembly station located above the bolt assembly station 400.

[0049] In this embodiment, both the gasket assembly station 300 and the bolt assembly station 400 are equipped with rotating seats 4 to facilitate the assembly of the gasket and bolt 100. Specifically, see Figure 3 As shown, the transmission component 5 includes two parallel guide rails, and a rotating seat 4 is disposed between the two guide rails. In this embodiment, the rotating seat 4 can also be vertically raised and lowered to lift the product upwards and detach it from the guide rails, thereby providing stable support for the product. In this embodiment, the product is placed on a carrier, and the transmission component 5 transports the product via the carrier.

[0050] In this embodiment, a temporary storage platform 6 for storing auxiliary tooling 1 is provided between the gasket assembly station 300 and the bolt assembly station 400. The temporary storage platform 6 can be raised and lowered, and the transport component 21 can reciprocate between the gasket assembly station 300, the bolt assembly station 400, and the temporary storage platform 6 along the transmission direction. In this embodiment, after the product is transferred to the gasket assembly station 300, the transport component 21 retrieves the auxiliary tooling 1 from the temporary storage platform 6 and assembles the auxiliary tooling 1 onto the product located at the gasket assembly station 300. Then, the assembly component 31 assembles the gasket. After the gasket assembly is completed, the transport component 5 transfers the product to the bolt assembly station 400. After the bolt assembly is completed at the bolt assembly station 400, the transport component 21 can remove the auxiliary tooling 1 from the product and transfer it to the temporary storage platform 6 for temporary storage, or the transport component 21 can directly transfer the auxiliary tooling 1 from the bolt assembly station 400 to the gasket assembly station 300.

[0051] In this embodiment, see Figure 3 As shown, the fastening device has two temporary storage platforms 6, one above the other, to ensure a sufficient supply of auxiliary tooling 1 and to allow for the alternating provision and storage of auxiliary tooling 1. In this embodiment, the transport component 21 can also be raised and lowered to facilitate the acquisition of auxiliary tooling 1 from the temporary storage platform 6 and the assembly and disassembly of auxiliary tooling 1.

[0052] In this embodiment, see Figure 4 As shown, the auxiliary tooling 1 includes a tooling body 11 and a transfer seat 12 for cooperating with the transport component 21. The transfer seat 12 is fixed to the upper part of the tooling body 11, and positioning holes 111 are provided in the tooling body 11. The transport component 21 transfers the auxiliary tooling 1 through the transfer seat 12 located at the upper part, making the transfer operation more convenient and facilitating the positioning and assembly of the auxiliary tooling 1. In this embodiment, the tooling body is provided with a plurality of positioning holes 111 located on the circumferential outer side of the transfer seat 12. The plurality of positioning holes 111 are distributed at intervals along the circumference of the transfer seat 12, and the transfer seat 12 will not affect the assembly of the gasket and bolt 100. Specifically, in this embodiment, the bolt fastening device constitutes a stator fixing device, which uses bolts 100 to fix the assembled stator. The stator is provided with a plurality of mounting holes distributed at intervals along the circumference.

[0053] In this embodiment, the outer periphery of the transfer seat 12 is provided with an inwardly recessed slot 121, and the transport member 21 includes a snap-fit ​​part 211 that can be inserted into the slot 121 and clamp and fix the transfer seat 12. The engagement of the snap-fit ​​part 211 with the slot 121 improves the stability of the auxiliary tooling 1 during transport. Specifically, see... Figure 1 As shown, the transport component 21 includes two snap-fit ​​parts 211, which can come together to clamp the transfer seat 12.

[0054] In this embodiment, the positioning structure includes a positioning groove 112 disposed at the lower part of the auxiliary tooling 1. Specifically, see [link to documentation]. Figure 5 As shown, the auxiliary tooling 1 has a downward-facing mounting cavity 113, and positioning grooves 112 are distributed around the periphery of the mounting cavity 113. When the auxiliary tooling 1 is assembled onto the product, at least part of the product is located in the mounting cavity 113, and part of the product is inserted into the positioning grooves 112, thereby achieving positioning and restricting the relative movement of the auxiliary tooling 1 and the product. Specifically, the conveying component 21 covers the auxiliary tooling 1 onto the product, so that the top of the product is inserted into the mounting cavity 113 and the positioning grooves 112, thereby achieving positioning.

[0055] In this embodiment, the depth of the positioning hole 111 is greater than the thickness of the gasket, allowing the gasket assembled on the auxiliary fixture 1 to be completely accommodated within the positioning hole 111, thereby better maintaining the stability of the gasket. Gaskets typically increase the contact area, so their diameter is usually greater than the maximum diameter of the cross-section of the bolt 100 end. Therefore, in this embodiment, the diameter of the positioning hole 111 is greater than the maximum diameter of the cross-section of the bolt 100 end, facilitating the removal of the auxiliary fixture 1 from the product. The disassembly operation can be completed by simply lifting the auxiliary fixture 1 upwards using the transport component 21.

[0056] In this embodiment, see Figure 9 As shown, the bolt feeding mechanism 201 is a pusher, which can supply bolts 100 neatly and sequentially. See also... Figure 9 , Figure 10 As shown, the loading component 32 is mounted on the robotic arm and moved by the robotic arm. In this embodiment, the robotic arm has two loading components 32, each capable of clamping a bolt 100 and then transporting it to the bolt assembly station 400 for assembly. The purpose of setting up two loading components 32 is to balance the time for oiling operations, bolt 100 assembly, and tightening selection, thereby optimizing the production cycle of the equipment and improving efficiency.

[0057] In this embodiment, see Figure 7 , Figure 10As shown, the material handling mechanism includes a material handling component for transferring the bolt 100 to the fixing member 81. Both the material handling component and the loading component 32 include two spaced-apart fixing claws 321 that can respectively fix the bolt 100. A clearance groove 322 is formed between the two fixing claws 321, allowing the clamping claw 811 of the fixing member 81 to be inserted. The two fixing claws 321 can improve the stability of clamping and fixing, and the clearance groove 322 can improve the cooperation effect with the clamping claw 811.

[0058] In this embodiment, see Figure 11 As shown, the assembly 31 is configured to move both horizontally and vertically to enable the picking, transferring, and assembling of the gasket. In this embodiment, the assembly 31 acquires and secures the gasket by adsorption. See also... Figure 11 As shown, a vision module is provided on one side of the assembly 31 to ensure the accuracy of material picking and loading.

[0059] In summary, the bolt fastening equipment of this embodiment can fully automate the entire process of bolt 100 loading, unloading, oiling, assembly, and tightening. Simultaneously, the equipment can also automate the loading and assembly of washers. To prevent disturbance to the washers, the equipment is equipped with auxiliary fixture 1 for positioning and fixing the washers. The assembly and disassembly of auxiliary fixture 1 are also automated. Thus, the equipment achieves fully automatic operation, improving efficiency and ensuring quality.
