Description

Technical Field

[0001] This invention relates to the field of hardware assembly equipment technology, specifically to an automatic hardware assembly device. Background Technology

[0002] As core components of high-end mechanical equipment such as automobile engines, hardware parts directly determine the operational stability and service life of end products through their assembly precision, efficiency, and adaptability. In the automotive manufacturing industry, the assembly process of engine-related hardware parts is complex, requiring precise docking and pressing of multiple specifications of parts in sequence. Furthermore, the size and shape of hardware parts corresponding to different engine models vary, placing extremely high demands on the flexible production capabilities of assembly equipment.

[0003] Chinese Patent Publication No. CN120921046A discloses an automatic assembly device for hardware parts, including a mounting frame on which a chain guide circulation line and a vibratory feeder are mounted; the chain guide circulation line is equipped with several hardware seats; the vibratory feeder has several units evenly distributed along the chain guide circulation line, and the vibratory feeder transports various hardware parts to the hardware seats. The hardware seats are used to hold the hardware parts, and an energized coil is installed inside the hardware seats. The energized coil is powered by the mounting frame. When the hardware parts fall into the hardware seats or are clamped by the unloading robot, four L-shaped clamping plates unfold; at other times, the four L-shaped clamping plates are in a retracted state to ensure the accuracy of subsequent assembly. The upper and lower conductive blocks at both ends of the energized coil are in contact with pole piece one and pole piece two, respectively. The magnetic metal body attracts / repels the magnetic iron core, reducing the bounce of the metal body and avoiding damage to the surface of the metal parts caused by repeated bounces. However, in actual use, the transmission mechanism is mostly a fixed indexing design, and the angle of a single rotation cannot be adjusted. It can only adapt to the workstation requirements of a single assembly process. When the assembly steps of the parts are increased or decreased, the entire transmission assembly needs to be replaced, resulting in poor versatility. At the same time, the replacement process of the material carrying and limiting components is cumbersome, relying on special tools for disassembly and fixing, resulting in a long changeover cycle and making it difficult to meet the needs of rapid switching and assembly of parts of multiple specifications. Summary of the Invention

[0004] The main objective of this invention is to provide an automatic assembly device for hardware parts, which can effectively solve the problems that most transmission mechanisms are designed with fixed indexing, the angle of a single rotation cannot be adjusted, and they can only adapt to the workstation requirements of a single assembly process.

[0009] Preferably, the intermittent component includes a driven rod, which is rotatably mounted on the bottom wall of the inner cavity of the mounting housing. The lower part of the outer surface of the driven rod is connected to the lower part of the outer surface of the transmission component via a belt transmission mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the device uses multiple sets of intermittent mechanisms with different indexing angles in the intermittent component to cooperate with the switching structure of the transmission component two. The operator can drive the driven ring to slide by pulling the handle up and down, and quickly switch the intermittent mechanism of the transmission connection to realize the indexing rotation of the fixed device at different angles such as 90° and 60° in a single operation. More angle adaptations can be expanded by adding intermittent mechanisms to meet the workstation docking requirements of different parts assembly steps, and greatly improve the versatility of the device.

[0016] 2. In this invention, the fixing device adopts a bidirectional screw-driven fixing mechanism. The operator only needs to rotate the torsion wheel to control the insertion and removal of the fixing pin, so as to quickly lock and unlock the material placement part without special tools. The limiting mechanism, through the overlapping connection of the sector plate and the insertion and removal design of the positioning plate, can easily adjust the position of the braking component or replace the sector plate, adapting to the assembly and process requirements of different specifications of hardware parts. The changeover operation is efficient and convenient, significantly shortening the production preparation cycle and improving flexible production capabilities.

[0017] 3. In this invention, the device integrates the entire process of material storage, conveying, cutting and sorting, assembly and unloading. Through the linkage design of the conveying components and the transmission mechanism, the feeding and indexing rotation are synchronously connected. No manual intervention is required for the transmission and feeding coordination. The finished product unloading mechanism automatically completes the grabbing and transfer of finished products, realizing the fully automated operation of the assembly process. Only one worker is needed to complete the material replenishment and equipment monitoring, which greatly reduces the input of manpower and improves production efficiency.

[0018] 4. In this invention, the material conveying mechanism, intermittent components, and fixing mechanism of the device are all modularly designed. Each component is assembled independently and reliably connected, which facilitates daily maintenance and troubleshooting. The driven rod can be equipped with intermittent mechanisms with different indexing angles as needed. The number of fixing mechanisms can be expanded by arraying the two fixing plates, which can be adapted to the assembly of more specifications and more processes of hardware parts. It has strong expandability in the later stage and reduces the cost of equipment upgrades. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, as Figure 1 - Figure 20 As shown, this embodiment discloses an automatic assembly device for hardware parts, including a placement table 1. A material conveying device 2 and a control component 3 are sequentially arranged on one side of the upper end of the placement table 1. A material conveying mechanism 6 and a vibrating conveying mechanism 11 are arranged on the other side of the upper end of the placement table 1. A finished product unloading mechanism 10 is arranged on one side of the middle of the upper end of the placement table 1. A material conveying device 4 is arranged on the other side of the middle of the upper end of the placement table 1. A material storage mechanism 5 is fixedly installed on the upper end of the placement table 1 on the input side of both the material conveying device 2 and the material conveying device 4. A transmission device 7 is arranged in the middle of the upper end of the placement table 1. A fixing device 8 is arranged on the upper end of the transmission device 7. A limiting mechanism 9 is fixedly installed on the upper part of the outer surface of the transmission device 7 above the fixing device 8. The limiting mechanism 9 is provided with multiple auxiliary components adapted to the assembly process.

[0023] Specifically, during the assembly of automotive engine-related parts, workers first place the various hardware components that make up the target part into the vibrating conveyor mechanism 11 and the two material storage mechanisms 5. Then, the entire device is started by the control component 3. At this time, the hardware components in the vibrating conveyor mechanism 11 and the two material storage mechanisms 5 are sequentially conveyed to the fixed device 8 by the material conveying device 1 2, the material conveying device 2 4, and the material conveying mechanism 6. During this process, while conveying the hardware components, the material conveying device 1 2 drives the transmission device 7 to operate, which in turn drives the fixed device 8 to rotate step by step. During the rotation of the fixed device 8, the material conveying device 1 2, the material conveying device 2 4, and the material conveying mechanism 6 sequentially place the corresponding hardware components into the designated positions of the fixed device 8. Then, with the cooperation of the limiting mechanism 9, the fixed device 8 completes the precise assembly of the multiple hardware components placed on it. After the assembly is completed, the finished product is picked up from the fixed device 8 by the finished product unloading mechanism 10 and conveyed to the next production process.

[0024] Furthermore, when assembling related parts of different models of automobile engines, due to the differences in the size and shape of the hardware accessories to be assembled, it is necessary to replace the material carrying components with suitable ones. At this time, the staff can quickly complete the disassembly and replacement of the material carrying components through the modular design of the fixing device 8 and the limiting mechanism 9 to adapt to the assembly needs of multiple specifications of parts.

[0025] To achieve the driving of transmission device 7, such as Figure 4 and Figure 5 As shown, the material conveying mechanism 6 includes a mounting plate 61, which is fixedly installed on the upper end of the placement platform 1. A cutting component 62 is provided on one side of the upper end of the mounting plate 61, a conveying component 63 is provided in the middle of the upper end of the mounting plate 61, and a transmission component 64 is provided on the other side of the upper end of the mounting plate 61.

[0026] Furthermore, such as Figure 6 As shown, the conveying component 63 includes a mounting frame 631, which is fixedly mounted on the upper end of the mounting plate 61. A conveying component 632 is provided on the upper part of the outer surface of the mounting frame 631, and a hydraulic cylinder 633 is provided on the lower part of the outer surface of the mounting frame 631. The output end of the hydraulic cylinder 633 is fixedly connected to the lower part of the outer surface of the conveying component 632.

[0027] Specifically, after the material storage mechanism 5 transports the parts to the cutting component 62, the cutting component 62 cuts and corrects the size of the parts. Unqualified parts are automatically sorted into the waste collection box, while qualified parts are transported to the upper part of the fixing device 8 by the conveying component 63. During the process of the conveying component 63 transporting the parts, the synchronous linkage transmission component 64 operates to provide power to the transmission device 7.

[0028] To limit the rotation direction of transmission device 7 and achieve unidirectional intermittent transmission, such as Figure 7 As shown, the transmission component 64 includes a transmission handle 641, which is slidably mounted on the upper end of the mounting plate 61. The upper part of the outer surface of the transmission handle 641 is fixedly connected to the output end of the hydraulic cylinder 633. A rack 642 is provided at the lower end of the transmission handle 641. A gear 643 is meshed with the upper part of the rack 642. A transmission rod 644 is fixedly connected to the middle part of the gear 643. The transmission rod 644 is rotatably mounted on the upper part of the mounting plate 61. A ratchet mechanism 646 is provided in the middle part of the outer surface of the gear 643. A transmission element 645 is provided on the side of the outer surface of the transmission rod 644 away from the gear 643.

[0029] Specifically, when the hydraulic cylinder 633 outputs power to drive the conveyor 632 to move towards the side closer to the fixed device 8, the hydraulic cylinder 633 simultaneously drives the transmission handle 641 to translate. The transmission handle 641 drives the gear 643 to rotate through the rack 642. At this time, under the one-way locking action of the ratchet mechanism 646, the transmission rod 644 only drives the gear 643 to rotate freely and does not drive the transmission component 645 to move, ensuring that the transmission device 7 remains stationary during the feeding process of the conveyor 632 and ensuring feeding accuracy.

[0030] Furthermore, after the conveyor 632 accurately places the accessory onto the upper end of the fixing device 8, the hydraulic cylinder 633 drives the conveyor 632 to reset to the side away from the fixing device 8. At this time, the rack 642 drives the gear 643 to rotate in the opposite direction, and the transmission rod 644 is unlocked through the ratchet mechanism 646 and drives the transmission component 645 to operate. Then, the transmission component 645 drives the transmission device 7 to complete one indexing rotation.

[0031] To enable the transmission device 7 to drive the fixed device 8 to achieve precise indexing rotation and adapt to the workstation requirements of different assembly processes, such as... Figure 8 As shown, the transmission device 7 includes a mounting shell 71, which is fixedly installed in the middle of the upper end of the placement platform 1. A transmission component 73 is provided in the middle of the inner cavity of the mounting shell 71. The upper end of the transmission component 73 extends to the upper part of the mounting shell 71. An intermittent component 72 is sleeved on the outer surface of the transmission component 73. The intermittent component 72 is rotatably installed in the middle of the inner cavity of the mounting shell 71.

[0032] Specifically, when the transmission component 645 is in operation, it synchronously drives the intermittent component 72 to rotate. The intermittent component 72 drives the transmission component 73 to rotate through the indexing transmission structure. In turn, the transmission component 73 drives the fixing device 8 to complete one indexing rotation of a set angle, ensuring that each workstation is accurately connected in sequence.

[0033] Furthermore, to address the differences in assembly processes for different parts, the angle of single rotation of the fixing device 8 needs to be adaptively adjusted according to the number of assembly steps. For example, when there are three assembly steps, the angle of single rotation of the fixing device 8 is set to 120°, and when there are six assembly steps, the angle of single rotation of the fixing device 8 is set to 60°, thereby achieving precise connection of multiple processes.

[0034] Furthermore, when it is necessary to adjust the single rotation angle of the fixing device 8, the operator can switch the transmission connection relationship between the transmission component 2 73 and the corresponding indexing mechanism in the intermittent component 72, so that the transmission component 2 73 drives the fixing device 8 to rotate through the adapted intermittent mechanism, thereby achieving adjustable and controllable indexing angles.

[0035] To precisely control the rotation angle of the fixing device 8, such as Figure 9 and Figure 10 As shown, the intermittent component 72 includes a driven rod 721, which is rotatably mounted on the bottom wall of the inner cavity of the mounting housing 71. The lower part of the outer surface of the driven rod 721 is connected to the lower part of the outer surface of the transmission component 645 through a belt transmission mechanism. Intermittent mechanism one 722 and intermittent mechanism two 723 are respectively provided on the middle and upper parts of the outer surface of the driven rod 721. The components of intermittent mechanism one 722 and intermittent mechanism two 723 that are away from the material conveying mechanism 6 are all sleeved on the outer surface of transmission component two 73. A connecting plate 724 is rotatably mounted on the inner cavity surface of the mounting housing 71 above intermittent mechanism two 723.

[0036] Specifically, intermittent mechanism 1 722 and intermittent mechanism 2 723 are two intermittent transmission mechanisms with different indexing angles. If the operator establishes a transmission connection with intermittent mechanism 1 722 through transmission component 2 73, intermittent mechanism 1 722 can drive the fixed device 8 to rotate 90° in a single rotation. If transmission component 2 73 establishes a transmission connection with intermittent mechanism 2 723, intermittent mechanism 2 723 can drive the fixed device 8 to rotate 60° in a single rotation.

[0037] Furthermore, when the fixing device 8 needs to achieve single rotation at other angles, the operator can add an intermittent mechanism with a corresponding indexing angle to the driven rod 721. Multi-angle adaptation can be achieved through the switching structure of the transmission component 73. Both the intermittent mechanism 722 and the intermittent mechanism 723 adopt existing mature intermittent transmission structures, and their specific internal structures will not be described in detail in this manual.

[0038] Furthermore, when the transmission component 645 rotates, it drives the driven rod 721 to rotate synchronously through the belt transmission mechanism. The driven rod 721 drives the intermittent mechanism 1 722 and the intermittent mechanism 2 723 to operate simultaneously. At this time, one of the intermittent mechanisms, which is connected to the transmission component 2 73, drives the connecting plate 724 to rotate through the transmission component 2 73. In turn, the connecting plate 724 drives the fixing device 8 to complete the indexing rotation.

[0039] To achieve transmission switching control of intermittent component 72, such as Figure 10 and Figure 11 As shown, the transmission component 2 73 includes a fixed disk 1 731, which is fixedly installed on the upper end of the placement platform 1. A support member 732 is provided in the middle of the fixed disk 1 731, and a driven member 733 is rotatably installed on the outer surface of the support member 732.

[0040] Furthermore, such as Figure 12 and Figure 13 As shown, the support member 732 includes a support handle 7321, which is fixedly installed in the middle of the fixed disk 731. A handle 7322 is slidably installed in the middle of the support handle 7321, and a connecting ring 7323 is provided at the lower end of the handle 7322.

[0041] Furthermore, such as Figure 13 As shown, the driven member 733 includes a driven cylinder 7331, which is rotatably mounted on the outer surface of the support handle 7321. The upper part of the outer surface of the driven cylinder 7331 is fixedly connected to the middle part of the connecting plate 724. A driven ring 7332 is slidably mounted on the upper part of the outer surface of the driven cylinder 7331. A plurality of connecting blocks 7333 are provided on the inner surface of the driven ring 7332. The plurality of connecting blocks 7333 extend into the interior of the driven cylinder 7331. The middle part of the plurality of connecting blocks 7333 is rotatably connected to the outer surface of the connecting ring 7323.

[0042] Specifically, when it is necessary to adjust the single rotation angle of the fixing device 8, the operator pulls the handle 7322 up and down, causing the connecting ring 7323 to move axially along the support handle 7321. The connecting ring 7323 drives the driven ring 7332 to slide up and down synchronously through multiple connecting blocks 7333, so that the outer surface of the driven ring 7332 engages with the input end of the intermittent mechanism 1 722 or the intermittent mechanism 2 723, and then the corresponding intermittent mechanism drives the driven cylinder 7331 to rotate. The driven cylinder 7331 drives the fixing device 8 to complete the rotation of the set angle through the connecting plate 724.

[0043] Example 2: This example further improves the fixing device 8 based on Example 1, such as... Figure 14 and Figure 15 As shown, the limiting mechanism 9 includes a limiting plate 91, which is fixedly installed on the upper part of the outer surface of the support member 732. Multiple sector plates 92 are inserted into the outer surface of the limiting plate 91, and the connection points of the multiple sector plates 92 are stacked in sequence. Positioning plates 93 are inserted into the connection points of the multiple sector plates 92.

[0044] Specifically, the upper part of the sector plate 92 is equipped with a braking component, while some parts are not equipped with a braking component. Their arrangement is preset according to the rotation angle of the fixing device 8 and the requirements of the assembly process, such as... Figure 14 As shown, this is to precisely coordinate the assembly actions at each workstation.

[0045] Furthermore, when the assembly process changes and it is necessary to adjust the position of the braking component at the upper end of the limiting mechanism 9 or add a new braking component, the operator can first pull out the positioning plates 93 on both sides of the sector plate 92 to be disassembled to release the limitation on the sector plate 92. Then, the old sector plate 92 is taken out, and the new sector plate 92 equipped with the corresponding braking component is inserted into the corresponding slot of the limiting plate 91. Then, the positioning plate 93 is inserted into the preset hole to complete the quick replacement and adjustment of the braking component. No special tools are needed, and the operation is convenient and efficient.

[0046] To facilitate quick replacement of material-bearing components by staff and to adapt to the assembly of hardware of different specifications, such as Figure 16 and Figure 17 As shown, the fixing device 8 includes a fixing plate 81, which is rotatably mounted on the upper end of the mounting shell 71. Multiple fixing mechanisms 82 are arranged in an array on the outer side of the fixing plate 81. Material placement parts 83 are arranged at the upper end of the multiple fixing mechanisms 82. Multiple limiting grooves 811 are arranged in an array at the lower end of the fixing plate 81. The multiple limiting grooves 811 are adapted to the connecting plate 724 for use.

[0047] Specifically, the upper protrusion of the connecting plate 724 is engaged in the limiting groove 811 of the fixed plate 2 81. When the connecting plate 724 rotates, the fixed plate 2 81 rotates synchronously through the cooperation of the protrusion and the limiting groove 811. After the fixed plate 2 81 rotates a set angle under the drive of the intermittent component 72, if one of the material placement components 83 moves to the feeding position corresponding to the material conveying device 1 2, the material conveying device 1 2 will put the corresponding accessory into the material placement component 83. After feeding is completed, the fixed plate 2 81 rotates a set angle again, and the material placement component 83 moves to the transition position without the feeding component. Then the fixed plate 2 81 continues to rotate a set angle, and the material placement component 83 docks with the material conveying device 1 2. The material conveying device 24 places another accessory into the material placement component 83, stacking it on top of the previous accessory. Then, the fixed plate 281 rotates to a set angle again, and the material placement component 83 connects to the material conveying mechanism 6. The material conveying mechanism 6 places the third accessory into the material placement component 83. After three feedings are completed, the fixed plate 281 continues to rotate to a set angle, and the material placement component 83 moves to the upper auxiliary pressing component of the limiting mechanism 9. The auxiliary pressing component moves downward to tightly press and assemble the three accessories into one piece. Finally, the fixed plate 281 rotates to the finished product unloading station, and the finished product unloading mechanism 10 picks up the assembled finished product from the material placement component 83, completing a single assembly cycle.

[0048] Furthermore, as the fixed plate 2 81 drives multiple material placement parts 83 to pass through the material conveying device 1 2, the material conveying device 2 4, the material conveying mechanism 6, and the finished product unloading mechanism 10 in sequence, the auxiliary components at the upper end of the limiting mechanism 9 move synchronously to achieve functions such as positioning, guiding, and pressing of the material placement parts 83, and to accurately coordinate with the assembly operations of each process.

[0049] To enable rapid disassembly and replacement of material placement component 83 and improve the flexible production capacity of the device, such as Figure 18 — Figure 20 As shown, the fixing mechanism 82 includes a fixing plate 821, which is fixedly installed on the outer surface of the second fixing disk 81. A follower 822 is provided at the lower end of the fixing plate 821. Both sides of the outer surface of the follower 822 are threadedly connected to connecting parts 823. A torsion wheel 824 is provided on one side of the outer surface of the follower 822. Fixing pins 825 are provided on both sides of the upper end of the two connecting parts 823. The fixing pins 825 are slidably installed on the inner wall of the second fixing disk 81.

[0050] Specifically, when assembling parts of different specifications requires changing the material placement component 83, the operator can drive the driven component 822 to rotate by rotating the torsion wheel 824. With the help of the thread transmission characteristics of the two-way screw, the connecting components 823 on both sides are driven to move closer or further away from each other along the axis of the driven component 822. Then, the two connecting components 823 drive the corresponding fixing pins 825 to move synchronously, so as to realize the rapid locking and unlocking of the material placement component 83, so as to speed up the changeover process and adapt to the assembly needs of hardware parts of different specifications.

[0051] Furthermore, when replacing the material placement component 83, the operator rotates the torsion wheel 824 in the forward direction. The driven component 822 drives the connecting components 823 on both sides to move away from each other. The connecting components 823 drive the fixing pin 825 to be pulled out from the positioning holes on both sides of the material placement component 83, releasing the locking of the material placement component 83. At this time, the old material placement component 83 can be directly removed. Then, the material placement component 83 adapted to the new part is placed in the positioning area at the upper end of the fixing mechanism 82. The torsion wheel 824 is rotated in the reverse direction, driving the connecting components 823 on both sides to move closer to each other, so that the fixing pin 825 is inserted into the positioning hole of the new material placement component 83, completing the precise positioning and fixing of the material placement component 83. The entire replacement process does not require special tools and can be operated by a single person. The changeover time is short, significantly improving the production adaptability of the device.
