Description

Technical Field

[0001] This invention relates to the field of piston manufacturing and processing equipment technology, specifically to a fully automatic rubber-coated piston manufacturing equipment. Background Technology

[0002] As a core component in power or transmission machinery such as engines and compressors, pistons typically require a rubber coating with specific properties on their outer surface to enhance sealing, wear resistance, and provide cushioning and shock absorption. Currently, the traditional processing methods for rubber coating pistons largely rely on manual or semi-manual operations. This approach is not only inefficient and labor-intensive, but also makes it difficult to guarantee consistent product quality. It is highly dependent on the operator's skill level, leading to significant fluctuations in finished product yield.

[0003] To overcome the aforementioned drawbacks, some automated or semi-automated overmolding equipment has emerged in the market, improving production efficiency and product quality to some extent. However, existing automated equipment still has significant limitations when handling specific types of pistons. Most of these machines employ one-piece molding or fixed-length sleeve processes, and their structures and molds are typically designed for standard-sized pistons, lacking sufficient flexibility and compatibility. When faced with pistons that are longer or non-standard in size, existing equipment often struggles to adapt, failing to complete effective overmolding and subsequent processing. Production would then require replacing the entire mold set or undertaking large-scale equipment modifications, leading to soaring costs and long response times.

[0004] There is currently no mature and efficient automated solution, which makes the automated overmolding production of pistons of special lengths a technical problem that urgently needs to be solved in the industry. Summary of the Invention

[0016] This invention provides a fully automated rubber-coated piston production equipment. It has the following beneficial effects: 1. This invention seamlessly integrates multiple functional modules such as conveying components, transfer components, adhesive bonding components, sizing components, and cutting components into one unit, realizing fully unmanned operation from piston feeding, posture adjustment, adhesive bonding, sizing, to the final automated trimming by the piston rotation driven by the internal expansion gripper and the precision cutting tool. The processes are closely connected and run smoothly, greatly reducing the production cycle and reducing the dependence on manual labor.

[0017] 2. This invention, through its enclosed structural design and automated cleaning function, ensures a clean production environment and long-term stable equipment operation. The overall outer shell effectively isolates the production process from the external environment, preventing contamination by impurities. At the same time, the matching cleaning components can automatically and centrally clean up the waste generated during the cutting process, avoiding equipment failure or downtime that may be caused by waste accumulation, thereby ensuring that the entire production line can operate continuously and reliably for a long time.

[0018] 3. This invention ensures high consistency and stable quality of the final product through multiple precise control mechanisms. The detector in the conveying component and the deflector in the transfer component work together to ensure the uniformity of the processing posture of all pistons from the source. The sizing component precisely controls the outer diameter of each finished product through the forced shaping of the pressure hammer and sizing sleeve.

Detailed Implementation

[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] Please see the appendix Figure 1 - Appendix Figure 13 This invention provides a fully automatic rubber-coated piston production equipment, including an outer shell 1. The outer shell 1 is provided with a conveying component 2 for linearly conveying the piston. The conveying component 2 is provided with a transfer component 3 for non-linearly transferring the piston. The output end of the conveying component 2 is provided with a pressing component 4 for wrapping the piston with rubber. The output end of the pressing component 4 is provided with a sizing component 5 for reinforcing the rubber that is just covering the piston. The output end of the sizing component 5 is provided with a cutting component 6 for trimming excess rubber on the piston. The cutting assembly 6 includes a C-shaped frame 601, which is fixedly connected to the inner bottom surface of the outer shell 1. The C-shaped frame 601 is located outside the sizing assembly 5. An internal expansion gripper 602 and a cylinder 603 are fixedly connected inside the C-shaped frame 601. A mounting plate 604 is fixedly connected to the output end of the cylinder 603. An electric telescopic rod 605 is fixedly connected to the lower surface of the mounting plate 604. An installation tube 606 is fixedly connected to the output end of the electric telescopic rod 605. A micro motor 607 is fixedly connected to the outer surface of the installation tube 606. The output end of the micro motor 607 passes through the installation tube 606 and is fixedly connected to a fixed shaft 608. The fixed shaft 608 is rotatably connected inside the installation tube 606. A blade 609 is fixedly connected inside the fixed shaft 608 by bolts.

[0023] Specifically, in the fully automated rubber-coated piston production process, the entire equipment operates within a sealed, clean space provided by the outer casing 1. The piston sequentially passes through the linear feeding of the conveying component 2, the attitude adjustment and gripping transfer of the transfer component 3, the automatic rubber coating of the pressing component 4, and the reinforcement and shaping of the sizing component 5, before being sent to the cutting component 6 for final finishing. To ensure the stability of the cutting process, the C-shaped frame 601 provides a solid mounting base for all moving parts of the entire cutting station. Once the piston is in place, the internal expansion gripper 602 expands from inside the piston, firmly clamping the piston without damaging the externally coated rubber layer, and preparing to drive its rotation. Cylinder 603 drives mounting plate 604 to achieve macroscopic position adjustment of the entire tool assembly, enabling it to move to a suitable processing area. Micro motor 607 drives fixed shaft 608 and end blade 609 to deflect. Then, electric telescopic rod 605 precisely controls the position of mounting tube 606 and tool through its telescopic action, thereby determining the feed rate of blade 609 to ensure cutting depth and accuracy. After the tool angle and depth are set, internal expansion gripper 602 drives piston to rotate, so that excess film material on it is precisely removed by high-speed rotating blade 609, thus trimming a finished product that meets specifications.

[0024] See attached document Figure 5 The conveying assembly 2 includes a feed channel 201, which is fixedly connected inside the outer shell 1. One end of the feed channel 201 passes through the outer shell 1 and connects to the outside. The other end of the feed channel 201 is fixedly connected to an L-shaped frame 202. A detector 203 is fixedly connected inside the L-shaped frame 202. The detector 203 is used to detect the shape and orientation of the piston. A pneumatic push rod 1 204 and a pneumatic push rod 205 are fixedly connected inside the outer shell 1. The output end of the pneumatic push rod 1 204 is slidably connected inside the feed channel 201. The pneumatic push rod 205 is located outside the feed channel 201. The pushing directions of the pneumatic push rod 1 204 and the pneumatic push rod 205 are perpendicular to each other.

[0025] Specifically, as the starting point of the automated production process, the piston is guided in an orderly manner to the L-shaped frame 202 via the feed channel 201, which serves as a standardized entry point. The L-shaped frame 202 provides a stable detection benchmark platform for the piston, enabling the internal detector 203 to accurately identify the presence or absence of the piston and determine whether its orientation is correct, thus completing the first quality control step. After the detection is completed, two pneumatic push rods with clearly defined functions immediately perform sorting actions. Pneumatic push rod one 204 is specifically responsible for pushing the pistons with incorrect orientation away from the main line, allowing them to enter the subsequent attitude adjustment process. Pneumatic push rod two 205 pushes all pistons with correct orientation to the next workstation, realizing automated material screening and directional conveying of qualified products, thus providing a guarantee for subsequent precise coating operations.

[0026] See attached document Figure 4 and attached Figure 5 The transfer assembly 3 includes a buffer plate 301, which is fixedly connected to the outer surface of the feed channel 201. A deflector 302 is fixedly connected inside the outer shell 1. The deflector 302 is used to change the orientation of the piston. The input end of the deflector 302 is close to the output end of the feed channel 201 and the input end of the buffer plate 301. A cylinder 303 and a limit rod 304 are fixedly connected inside the outer shell 1. An external gripper 305 is fixedly connected to the output end of the cylinder 303. The external gripper 305 is slidably connected to the outer surface of the limit rod 304.

[0027] Specifically, in the transfer component 3, for pistons with incorrect orientation, the steering device 302 adjusts their posture by rotating itself, achieving automated correction of the material orientation and ensuring the uniformity of subsequent processing. All pistons with correct orientation are uniformly pushed to the buffer plate 301. The buffer plate 301 serves as a material storage and buffering platform, orderly gathering pistons and forming a stable queue to be gripped, effectively connecting the preceding and following processes. When transfer is required, the cylinder 303, as the power source, is activated, driving the external gripper 305 to perform precise gripping actions, picking up a single piston from the buffer plate 301. During this process, the limit rod 304 provides a precise guide path for the movement of the external gripper 305, ensuring the accuracy of its gripping and release positions, and finally completing the non-linear, high-precision transfer of pistons from the loading area to the pressing station.

[0028] See attached document Figure 1 - Appendix Figure 7The pressure bonding assembly 4 includes two buffer platforms 401, which are fixedly connected to the inner bottom surface of the outer shell 1. A clamp 402 is slidably connected to both sides of the outer surface of one buffer platform 401. The clamp 402 is used to receive and transfer the position of the piston. The pressure bonding assembly 4 also includes a support frame 403, which is fixedly connected to the inner bottom surface of the outer shell 1 and located between the two buffer platforms 401. A cylinder 404 is fixedly connected to the top of the support frame 403, and a sliding plate 405 is fixedly connected to the output end of the cylinder 404. The sliding plate 405 slides... Connected to the outer surface of the support frame 403, the lower surface of the sliding plate 405 is fixedly connected to the external gripper 406. The bottom of the support frame 403 is fixedly connected to the cylinder 407 and multiple cylinders 408. The multiple cylinders 408 surround the cylinder 407. The output end of the cylinder 407 is fixedly connected to the mounting cone 409. The output end of the cylinder 408 is fixedly connected to the mounting push plate 410. The mounting push plate 410 is located between the two buffer platforms 401. The mounting push plate 410 has a hole 411 inside, which penetrates the upper and lower surfaces of the mounting push plate 410.

[0029] Specifically, in the workflow of the pressure bonding assembly 4, the two buffer platforms 401 first serve as temporary storage and buffer areas for the pistons, receiving the pistons delivered from upstream in an orderly manner. Then, the gripper 402 is activated, precisely transferring the pistons from the buffer platforms 401 to the machining center, providing accurate positioning for subsequent gripping and pressure bonding actions. The support frame 403 provides a stable mounting platform for the entire pressure bonding actuator. Once the piston is in place, the external gripper 406, mounted on the sliding plate 405, is driven by the cylinder 404 to grip and vertically press the piston by moving the sliding plate 405 up and down. Simultaneously, the cylinder... The mounting cone 409, which is responsible for positioning, uses its conical structure to guide the film to unfold and initially cover it when the piston is pressed in. Then, multiple cylinders 408 around it synchronously drive the mounting push plate 410 to apply uniform pressure to the film from the outside, ensuring that the film fits tightly against the outer wall of the piston. During this process, the hole 411 in the center of the mounting push plate 410 provides the necessary channel for the movement of the mounting cone 409. Finally, the piston that has completed the coating is transferred by the clamp 402 to another buffer platform 401, waiting to enter the next process, thus realizing a complete automated feeding, positioning, coating and transfer process.

[0030] See attached document Figure 8 and attached Figure 9The sizing assembly 5 includes a sliding frame 501, with a slider 502 slidably connected inside the sliding frame 501. Two electric telescopic rods 503 are fixedly connected to the outer surface of the slider 502. The output ends of the two electric telescopic rods 503 pass through the slider 502 and are fixedly connected to a support platform 504. A slider 505 is slidably connected inside the sliding frame 501, and the slider 505 is located above the slider 502. An external gripper 506 is fixedly connected inside the slider 502. The sizing assembly 5 also includes a support frame 2. 507, the second support frame 507 is fixedly connected to the inner bottom surface of the outer shell 1. The second support frame 507 is located outside the sliding frame 501. The top of the second support frame 507 is fixedly connected to the fifth cylinder 508. The output end of the fifth cylinder 508 is fixedly connected to the second sliding plate 509. The second sliding plate 509 is slidably connected to the outer surface of the second support frame 507. The lower surface of the second sliding plate 509 is fixedly connected to the pressure hammer 510. The inner bottom surface of the outer shell 1 is fixedly connected to the sizing sleeve 511. The sizing sleeve 511 is located directly below the pressure hammer 510.

[0031] Specifically, upon entering the sizing assembly 5, to achieve seamless connection between receiving and transferring, two electric telescopic rods 503 are activated first, extending the support platform 504 as a precise transition platform to a designated position to stably receive the piston falling from the previous process. Subsequently, the external gripping jaws 506, mounted on sliders 502 and 505, move along the guide path provided by the sliding frame 501 and perform gripping, picking up the piston from the support platform 504 and precisely placing it into the sizing sleeve 511 below. The support frame 2507 of the pressurization mechanism stabilizes the foundation and ensures the stability and precision of the subsequent pressurization process. After the piston is in place, the cylinder 508, which serves as the power source, drives the sliding plate 2509, which in turn drives the pressure hammer 510 to generate a strong and stable downward pressure. This forcefully presses the piston and the rubber layer into the sizing sleeve 511. The sizing sleeve 511 extrudes and shapes the rubber layer with the precise dimensions of its inner wall, which not only makes the bond between the rubber sheet and the piston stronger, but also ensures the high consistency of the outer diameter of the final product, thus completing the final shaping of the product dimensions.

[0032] See attached document Figure 8 and attached Figure 10 A worktable 610 is provided directly below the internal expansion gripper 602. The worktable 610 is fixedly connected to the inner bottom surface of the outer shell 1, and one end of the worktable 610 penetrates through the outer shell 1.

[0033] Specifically, in the final cutting process, the worktable 610 provides a stable processing base for the piston, ensuring the stability of the entire trimming process. After the piston is pushed into place, the internal expansion gripper 602 will tighten and firmly fix it from inside the piston. The key effect of this clamping method is that it can provide the necessary stable support for high-speed rotary cutting without contacting or damaging the external molded adhesive layer. Finally, the worktable 610, due to its design that partially penetrates the outer shell 1, directly serves as the output channel for the finished product to leave the equipment after the piston has finished cutting and been released.

[0034] See attached document Figure 11 and attached Figure 13 The cleaning component 13 includes a recovery pipe 1301, which is fixedly connected to the inner bottom surface of the outer shell 1. The recovery pipe 1301 is located on the outer side of the workbench 610. An absorption head 1302 and a fan 1303 are fixedly connected to the upper surface of the recovery pipe 1301. The output end of the absorption head 1302 is connected to the input end of the fan 1303. The output end of the fan 1303 is connected to the upper surface of the recovery pipe 1301. A cleaning plate 1304 is slidably connected inside the recovery pipe 1301. Two fixed blocks 1305 and a motor 1306 are fixedly connected to the inner bottom surface of the outer shell 1. A threaded rod 1307 is fixedly connected to the output end of the motor 1306. The threaded rod 1307 is rotatably connected between the two fixed blocks 1305. A movable sleeve 1308 is threadedly connected to the outer surface of the threaded rod 1307. The cleaning plate 1304 is fixedly connected to the movable sleeve 1308 through a fixed rod 1309.

[0035] Specifically, in the cleaning component 13, which operates simultaneously with the cutting process, the fan 1303, acting as the power source, generates a strong suction force after starting. This force is used to precisely capture the film waste generated during the cutting process through the absorption head 1302 and quickly suck it into the recycling pipe 1301 for centralized collection. This effectively avoids the impact of waste scattering on the cleanliness and operational stability of the equipment. When the waste accumulates to a certain level, the automatic waste cleaning program is activated. The motor 1306 drives the threaded rod 1307, which is stably supported by two fixed blocks 1305, to rotate. The rotation of the threaded rod 1307 then drives the moving sleeve 1308 on it to slide linearly. This linear motion is transmitted to the cleaning plate 1304 through the fixed rod 1309. The cleaning plate 1304 acts like a piston, pushing all the accumulated waste in the recycling pipe 1301 to the outlet for discharge at once. This achieves automated and periodic waste cleaning, ensuring the continuous and unobstructed operation of the equipment.

[0036] See attached document Figure 4 and attached Figure 6The outer surface of the limiting rod 304 is slidably connected to the feeder 306, which is used to feed the film onto the outer surface of the mounting cone 409. The inner surface of the outer shell 1 is fixedly connected to the cylinder 307, and the output end of the cylinder 307 is fixedly connected to the outer surface of the feeder 306.

[0037] Specifically, during the preparation of the film for the lamination process, cylinder 307, which serves as the power source, is activated, driving the feeder 306 to perform a precise feeding action. During this process, the limit rod 304 provides a precise guide path for the reciprocating motion of the feeder 306, ensuring that it reaches the predetermined position each time. The feeder 306 is responsible for accurately placing a single film on the outer surface of the mounting cone 409, thereby realizing fully automatic and high-precision feeding of the film material, preparing for the subsequent lamination process.

[0038] See attached document Figure 7 The bottom surface of the outer shell 1 is fixedly connected to a steering mechanism 2 7, a pneumatic push rod 3 8 and a conveyor belt 1 9. The steering mechanism 2 7, the pneumatic push rod 3 8 and the conveyor belt are located outside the output end of another buffer platform 401. The top of the outer shell 1 is fixedly connected to an internal expansion gripper 2 10, which is located directly above the conveyor belt 1 9.

[0039] Specifically, after the piston completes the pressing process, it needs to go through a series of complex transfer actions. First, the steering device 2 7 turns the piston to adjust it to a posture suitable for the next transfer process. Then, the pneumatic push rod 3 8 provides instantaneous thrust to smoothly push the piston onto the conveyor belt 1 9. The conveyor belt 1 9 then linearly transports the piston to the designated gripping point. Finally, the internal expansion gripper 2 10 located above descends and opens the piston from the inside to grip it, lifting it vertically without damaging the external adhesive layer, thus completing the key transfer from the pressing station to the sizing station.

[0040] See attached document Figure 8 and attached Figure 10 The inner bottom surface of the outer shell 1 is fixedly connected to a second conveyor belt 11 and a fourth pneumatic push rod 12. The second conveyor belt 11 is located between the output end of the sizing sleeve 511 and the worktable 610. The fourth pneumatic push rod 12 is located at one end of the second conveyor belt 11 and is on the same axis as the worktable 610.

[0041] Specifically, after the piston, having completed sizing, falls from below the sizing sleeve 511, it is directly received and transported by the second conveyor belt 11, realizing automated transmission from the sizing station to the cutting station. When the piston reaches the end of the conveyor belt, the fourth pneumatic pusher 12 is activated, using a precise pushing action perpendicular to the transmission direction to move the piston from the second conveyor belt 11 to the worktable 610 of the cutting assembly 6. This effectively ensures that the piston can be accurately delivered to the starting position of the cutting process and provides positioning for subsequent clamping and trimming.

[0042] Working principle: In actual use, the external feeding device conveys the piston through the feed channel 201 of the conveying component 2 to the area directly below the L-shaped frame 202. Then, the detector 203 inside the L-shaped frame 202 completes the presence and orientation detection. The piston with the wrong orientation is pushed into the deflector 302 by the pneumatic push rod 204. Then, the deflector 302 adjusts the posture of the piston with the wrong orientation by rotating itself. The piston with the correct orientation and the piston with the correct orientation are pushed onto the buffer plate 301 by the pneumatic push rod 205 to wait for the next process. The start cylinder 303 pushes the external gripper 305 to grab the piston from the buffer plate 301 and transfer it to the buffer platform 401 of the pressing component 4. At the same time, the cylinder 307 drives the feeder 306 to place the film on the outer surface of the mounting cone 409. Then, the clamp 402 moves the piston to the center of the mounting push plate 410 so that it is grabbed by the external gripper 406.After the external gripper 406 grasps the piston, it immediately begins pressing the film onto the piston. During this process, the external gripper 406, under the action of cylinder 404, moves the piston downward, while the film, under the action of cylinder 408, is pushed to the piston by the mounting push plate 410, thus covering the outer wall of the piston with the film. Immediately afterwards, the external gripper 406 releases the piston, and the clamping device 402 is activated again to send the piston to another buffer platform 401. As more and more pistons accumulate on the buffer platform 401, the first piston is pushed into the steering device 7. Steering mechanism 2 7 steers the piston, which is then pushed onto conveyor belt 1 9 by pneumatic push rod 3 8. At this time, internal expansion gripper 2 10 grabs the piston and lifts it up. Simultaneously, electric telescopic rod 1 503 is activated, extending the support platform 504 directly below internal expansion gripper 2 10. Internal expansion gripper 2 10 then releases the piston, which falls onto support platform 504. External gripper 3 506 then grabs the piston and transports it into sizing sleeve 511. Subsequently, cylinder 5 508 drives pressure hammer 510 downwards to apply pressure to the piston and rubber coating for sizing. After sizing, the piston falls onto the conveyor belt 11 from below the sizing sleeve 511, and is then pushed onto the worktable 610 of the cutting assembly 6 by the pneumatic push rod 12. It is then internally tightened and fixed by the internally expanding gripper 602 on the C-shaped frame 601. At this time, the micro motor 607 drives the blade 609 on the fixed shaft 608 to deflect at a predetermined feed angle. The internally expanding gripper 602 then drives the piston to rotate. Simultaneously, the cylinder 603 drives the mounting plate 604 and the electric telescopic rod 605 to control the precise position of the entire tool assembly. The excess rubber coating on the piston is cut according to the cutting depth. During the cutting process, the fan 1303 of the cleaning component 13 is started, and the waste is sucked into the recovery pipe 1301 through the absorption head 1302. After a period of time, the motor 1306 drives the threaded rod 1307 to rotate, which drives the moving sleeve 1308 to slide along the threaded rod 1307, thereby causing the cleaning plate 1304 in the recovery pipe 1301 to push out the waste. Finally, the finished product is pushed out of the outer shell 1 from the worktable 610 by the pneumatic push rod 12, realizing fully automated production.
