Description

Technical Field

[0001] This invention relates to the field of automotive VVT ​​system technology, specifically to an automotive timing sprocket assembly device. Background Technology

[0002] Variable valve timing (VVT) systems, under specific engine operating conditions, adjust intake and exhaust volume and timing and change valve overlap angle by controlling the advance and retardation of the intake valve opening angle. This increases intake charge and efficiency, better organizes intake swirl, and regulates cylinder combustion pressure and residual exhaust gas volume, thereby improving overall engine performance such as power, torque, emissions, fuel economy, and ride comfort. This resolves the technical contradictions between various performance indicators in traditional fixed valve timing engines. A VVT system generally consists of a phase adjuster assembly and an oil control valve. In existing technologies, the phase adjuster assembly is typically driven by a sprocket, which includes an outer sprocket and a rotor located inside the outer sprocket. The rotor and outer sprocket are fixed by blades and springs. Current technology often requires multiple pieces of equipment for assembly and handling, necessitating a highly automated and fast assembly system. Summary of the Invention

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings.

[0039] like Figure 1 As shown, this invention discloses an automotive timing sprocket assembly device, wherein the timing sprocket includes an outer wheel 11 and an inner rotor 12, comprising:

[0040] Rack 1, on which are mounted:

[0041] The feeding device 3 includes a movable feeding base 21 and a feeding and transfer assembly 22;

[0042] The transfer device includes a movable transfer seat 3, on which the product is transferred via the feeding and transfer assembly 22;

[0043] Step generation device 4 is used to generate a step difference between the outer wheel 11 and the inner rotor 12;

[0044] Blade and spring assembly device 5, used to install blade 13 and spring 14;

[0045] The step difference elimination device 6 eliminates the step difference between the outer wheel 11 and the inner rotor 12 after assembly.

[0046] The material unloading and inspection device 7 is used to inspect and unload the products.

[0047] In some implementation schemes, such as Figure 2 As shown, the transfer seat 3 includes: a base plate 31, a rotating table 32, a rotation drive component 33, and a support plate 34. The rotating table 32 is rotatably mounted on the base plate 31, and its rotatability is achieved through bearings. The rotation drive component 33 can be a motor, located at the bottom of the base plate 31, with its output end connected to the rotating table 32 to drive the rotating table 32 to rotate. The support plate 34 is fixedly mounted on the rotating table 32 and rotates with the rotating table 32. The support plate 34 has an annular protrusion in its middle. When the product is placed on the support plate 34... 4. When the product is positioned, the annular protrusion in the middle positions the through hole in the middle of the product; the support plate 34 also has a protrusion, the top of which forms a first receiving surface 35 for receiving the inner rotor 12, and the periphery of the support plate 34 forms a second receiving surface 36 for receiving the outer wheel 11. The height of the first receiving surface 35 is higher than that of the second receiving surface 36. The height difference between the first receiving surface 35 and the second receiving surface 36 is the step difference required before the product is installed, so that the inner rotor 12 is higher than the outer wheel 11, which facilitates the subsequent installation of the blades 13 and the spring 14. The transfer seat 3 enables transfer between various processing stations without manual handling, improving assembly efficiency. At the same time, the setting of the first receiving surface 35 and the second receiving surface 36 creates a step difference in the product, and the height of the step difference is controlled according to the usage requirements.

[0048] Furthermore, the frame 1 is equipped with a guide rail assembly 16 and a horizontal movement drive assembly 17. The base plate 31 moves along the guide rail assembly 16 under the drive of the horizontal movement drive assembly 17. The guide rail assembly 16 is mounted on the frame, and a slider is installed on the guide rail. The transfer seat 3 moves along the guide rail, causing the product to move to the subsequent step difference generating device 4, spring and blade assembly device, and step difference elimination device 6. The horizontal movement drive assembly 17 can be a lead screw motor assembly, with the nut on the lead screw connected to the base plate 31. Driven by the motor, the lead screw rotates, causing the base plate 31 to move horizontally reciprocally. By setting the guide rail assembly 16, the smooth movement of the transfer seat 3 is ensured, allowing for smooth flow between various processing actions.

[0049] In some implementation schemes, such as Figure 3-4 As shown, after the product is placed on the transfer seat 3, it is first transported to the step difference generating device 4. The step difference generating device 4 includes: a first mounting frame 41, a lifting drive component 42, a horizontal mounting plate 43, an outer lower pressure block 44, and an inner lower pressure block 45. The first mounting frame 41 is mounted on the frame 1. The lifting drive component 42 can be a cylinder, with its main body connected to the first mounting frame 41. Its extended end drives the horizontal mounting plate 43 to rise and fall. A guide rail can be installed on the first mounting frame 41 to ensure that the horizontal mounting plate 43 rises and falls smoothly. Multiple support columns 48 are provided at the bottom of the horizontal mounting plate. The bottom of the support columns 48 is connected to the outer lower pressure block 44. The outer lower pressure block 44 is an annular plate. The inner lower pressure block 45 is located inside the outer lower pressure block 44. A linear bearing is installed on the horizontal mounting plate 43. A moving shaft 46 is installed inside the linear bearing. The bottom of the moving shaft 46 is fixedly connected to the inner lower pressure block 45. The moving shaft 46 can move up and down along the linear bearing. A spring 47 is fitted onto the 46, with the bottom of the spring 47 contacting the inner pressing block 45, allowing the inner pressing block 45 to be floated. A stop is installed on the top of the moving shaft 46 to prevent the moving shaft 46 from detaching from the horizontal mounting plate 43. When pressing down, driven by the lifting drive 42, the outer pressing block 44 and the inner pressing block 45 move downward. The outer pressing block 44 presses down on the outer wheel 11, and the inner pressing block 45 presses down on the inner rotor 12. Due to the inner pressing block 4... 5 can retract under the action of spring 47, so after being pressed down, the outer pressing block 44 presses down the outer wheel 11, causing the outer wheel 11 to descend and its lower surface to contact the second bearing surface 36. At this time, the lower surface of the inner rotor 12 contacts the first bearing surface 35, so that the outer wheel 11 and the inner rotor 12 form a step difference. The inner rotor 12 has mounting grooves around its perimeter for mounting blades 13 and spring pieces 14. After the step difference is generated, the mounting grooves are exposed, which facilitates the installation of blades 13 and spring pieces 14.

[0050] In some implementations, the step difference elimination device 6 includes: a second mounting frame 61, a product lifting frame 62, and a product pressing component 63. The second mounting frame 61 is located on the side of the first mounting frame 41 and is used to eliminate the step difference between the outer wheel 11 and the inner rotor 12 after the spring 14 and blade 13 are installed, thus completing the assembly of the entire product. The second mounting frame 61 is mounted on the frame 1, and the product lifting frame 62 is mounted on the second mounting frame 61 and driven by the product lifting drive component 64. The product lifting drive component 64 can be a cylinder, and its main body is fixedly mounted on the second mounting frame 61. The bottom of the product lifting frame 62 is provided with a lifting plate 65 for lifting the product. The lifting plates 65 are symmetrically arranged, and there is a distance between the two lifting plates 65. During the movement of the transfer seat 3, when it reaches the step difference elimination device 6, the lifting plates 65 are located on both sides of the product, and then the lifting plates 65 rise to drive the product to rise.

[0051] The product lifting frame 62 has multiple guide columns. The product pressing component 63 is located inside the product lifting frame 62 and moves up and down along the guide columns. It is driven to press down by the pressing drive component 66, which can be a cylinder. The output end is connected to the product pressing component 63. When the lifting plate 65 lifts the product, the product pressing component 63 descends. Its bottom is a flat surface, which eliminates the step difference between the outer wheel 11 and the inner rotor 12. After the step difference is eliminated, the entire product lifting frame 62 descends, causing the product to fall back onto the transfer seat. Due to the connection between the inner rotor and the outer wheel by the blades and springs, the relative positions of the outer wheel and the inner rotor will remain unchanged at this time.

[0052] In some implementation schemes, such as Figure 5-10 As shown, the blade and spring assembly device 5 includes: an automatic blade feeding assembly 51, an automatic spring feeding assembly 52, a blade and spring assembly assembly 53, a side positioning assembly 54, and a rotary assembly assembly 55. The automatic blade feeding assembly 51 and the automatic spring feeding assembly 52 feed the spring assembly assembly. The automatic blade feeding assembly 51 and the automatic spring feeding assembly 52 use vibratory feeders for feeding. The two vibratory feeders push the spring 14 and the blade 13 into the first flow channel 57 and the second flow channel. After passing through the blade and spring assembly assembly 53, the spring 14 and the blade 13 enter the rotary assembly assembly 55 for installation. At this time, the rotary assembly assembly 55 is located on the upper side of the transfer seat 3, and the side positioning assembly 54 is located on the lower side of the rotary assembly assembly 55, which is used to position the inner rotor 12 before assembly.

[0053] Furthermore, the blade and spring assembly 53 includes: a transfer plate 531, a cover plate 532, and a toggle member 533. The transfer plate 531 is fixedly installed on the frame 1. The transfer plate 531 is provided with a transfer channel. The cover plate 532 is provided on the transfer plate 531 to cover the transfer channel and prevent the blade and spring from being restricted. It has a feeding port 534. The blade feeding vibratory plate arranges the blades 13 into the first channel 57. The end of the first channel 58 has a movable bearing block 56. The bearing block 56 has a groove that can carry the blade. After the blade 13 enters into the movable block 56, the movable block 56 carries the blade 13 and moves horizontally to the transfer channel under the drive of the cylinder to dock with the transfer channel. Under the toggle of the toggle member 533, it enters the transfer channel. Each time the toggle member 533 moves only one blade 13.

[0054] The vibratory feeder arranges the spring sheets 14 into the second flow channel, then the pneumatic gripper assembly 8 clamps the spring sheets 14, and then moves them to the loading port 534 under the drive of the linear module. The linear module can be a vertical movement module or a horizontal movement module, and the structure is existing technology. The pneumatic gripper assembly 8 can be a rotary pneumatic gripper module, which can clamp and rotate, and the specific structure is existing technology. At this time, there are blades 13 in the transfer flow channel inside the loading port 534, and then the pneumatic gripper assembly 8 places the spring sheets 14 on the blades 13. Since the blades 13 have slots for accommodating the spring sheets 14, such as... Figure 12 As shown, after the spring 14 is placed into the blade 13, the actuating member 533 is located on the side of the transfer plate 531 and reciprocates to push the combined spring 14 and blade 13 into the rotating assembly.

[0055] Furthermore, the transfer plate 531 is fixed to the frame 1 by a mounting base plate 535. A guide rail is mounted on the mounting base plate 535 along the length of the transfer plate 531. A movable plate 536 is mounted on the slider of the guide rail. Multiple equidistant fixed actuating seats 537 are mounted on the movable plate 536. Each actuating seat 537 has a slot, and an actuating element 533 is disposed within the actuating seat 537, with its end protruding from the actuating seat 537. The actuating element 533 is rotatably mounted via a pivot. Simultaneously, a horizontally mounted spring is installed inside the actuating seat 537. Figure 10As shown, under normal conditions, the end of the actuating element 533 extends out, and the moving plate 536 moves along the guide rail driven by the cylinder. The cylinder is set along the guide rail, and the actuating element 533 drives the product to move. After the end of the actuating element 533 extends into the transfer channel and moves the blade to a position, the cylinder retracts, and the actuating seat 537 retracts. During the retraction process, the spring is compressed, and the extended end of the actuating element 533 retracts into the actuating seat 537. The position of the blade remains unchanged. After passing the blade, the actuating element 533 extends out under the action of the spring, and the moving plate 71 continues to move to complete the next feeding action. Multiple actuating elements 533 work together to push the combined blade 13 and spring 14 into the cross groove 552 of the rotating assembly. By setting the actuating element 533 to drive the product to move, the blade is automatically fed, improving the assembly efficiency.

[0056] Furthermore, the rotary assembly assembly 55 includes a rotary plate 551 with a cross groove 552. The assembled spring piece 14 and blade 13 enter the cross groove 552. A cover plate covers the rotary plate 551 to prevent the blade 13 and spring piece 14 from detaching. The rotary plate 551 is vertically positioned with its side facing the transfer plate 531, allowing the blade 13 and spring piece 14 to enter the cross groove 552. Under the elastic force of the spring piece 14, the blade 13 and spring piece 14 placed in the cross groove 552 will not move. A motor is connected to the rotary plate 551 to drive its rotation. The rotary assembly assembly 55 also includes a vertically movable assembly rod 553 located on the rotary plate 551. On the upper side, it connects to the third mounting bracket 554, which is on the frame 1. A vertically positioned third moving module is mounted on the third bracket, which can be a lead screw motor module. This module drives the assembly rod 553 to move vertically. When the transfer seat 3 moves to the loading position, the actuating element 533 first drives the spring 14 and blade 13 into the cross groove 552. Then, the rotating plate 551 rotates, making the groove containing the blades vertical, aligning the bottom with the product's assembly position. The assembly rod 553 then extends into the cross groove 552, pressing the blades 13 and spring 14 down to the mounting position of the inner rotor 12, assembling them in place. During assembly, the transfer seat 3 rotates until all positions are completed. The rotation of the rotating plate 551 drives the blade movement, which has the advantage of enabling continuous loading and precise positioning of multiple blades 13 and springs 14, improving assembly efficiency and stability. Every 90-degree rotation of the rotating plate 551 aligns a slot containing the blade 13 and the spring 14 with the assembly rod 553, while the adjacent slots continue to receive assemblies from the transfer plate 531, thus realizing parallel operation of loading and assembly and shortening the assembly cycle of a single product.

[0057] Furthermore, the side positioning assembly 54 includes: an extension block 541, a connecting seat 542, and a positioning block 543. The extension block 541 is connected to the connecting seat 542, and the connecting seat 542 is connected to a positioning drive component, which can be a cylinder. The cylinder is installed at the bottom of the mounting base plate 535. The positioning drive component drives the extension block 541 to extend or retract. The positioning block 543 is located on the upper side of the extension block 541 and is fixedly installed with the mounting base plate 535. Its end faces the slot of the inner rotor 12 for mounting the blade 13 and the spring piece 14, and does not extend into the slot. When the blade 13 and the spring piece 14 move downward under the drive of the assembly rod 553, the spring piece 14 is deformed under the side limit of the positioning block 543, making the assembly smoother.

[0058] In some implementations, the unloading inspection device 7 includes a vision inspection device, which includes a camera, to detect whether multiple blades 13 on the product are installed. Then, the gripping component 9 grips the product, which can be achieved by a clamping cylinder. The loading and transfer component 22 can also be achieved by a clamping cylinder and is connected to a linear motion module to achieve product transfer, placing the product on the good product flow channel and the bad product flow channel for unloading, thereby achieving product classification and automatic unloading.

[0059] In the working process, the products to be assembled are first placed on the loading seat 21 by a robot or manually. Then the loading seat 21 moves, and the loading and transfer component 22 transfers the products to the transfer seat 3. The transfer seat 3 moves the products to the step difference generating device 4, so that a step difference is generated between the inner rotor 12 and the outer wheel 11. Then it moves to the assembly position. After the spring piece 14 and the blade 13 are pre-assembled, they first enter the rotating plate 551. The rotating plate 551 rotates, and the assembly rod 553 descends to assemble the blade 13 and the spring piece 14 into place. Multiple assembly is required. Then the transfer seat 3 moves the products to the step difference elimination device 6 to eliminate the step difference. After visual inspection, the products are classified and unloaded.

[0060] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this invention, and these all fall within the protection scope of this invention.
