Around the turntable are a valve cover feeding unit, a gravity valve disc feeding unit, a gravity ball feeding unit, a valve body feeding unit, and a valve body-valve cover riveting unit. A suspended support carrier is located within the workpiece cavity of each carrier. The support carrier has a positioning hole in its center, and the bottom wall of the workpiece cavity has a pressure-bearing surface. The valve cover feeding unit feeds an inverted valve cover into the workpiece cavity of the carrier, allowing the gravity valve rod to be inserted into the positioning hole, and the base to be placed on the support carrier.

This equipment integrates the turntable with various feeding and riveting units, creating a fully automated assembly system for fuel spill valves.

Description

Technical Field

[0001] This invention relates to the field of electric fuel pump assembly manufacturing technology, specifically to a fully automatic assembly and riveting equipment for a fuel side-turn valve. Background Technology

[0002] The fuel rollover valve is a key safety component of the automotive fuel pump assembly. Its main function is to close the fuel passage and prevent fuel leakage when the vehicle rolls over, through the linkage of an internal gravity valve disc and a gravity ball, thus ensuring vehicle safety. The fuel rollover valve typically consists of a valve body 100, a valve cover 200, a gravity valve disc 300, and a gravity ball 400. The valve cover 200 has a base 210 and a gravity valve stem 220 located at the upper end of the base. All components must be precisely assembled and riveted to ensure a robust structure and reliable sealing. The existing assembly process for fuel spill valves mostly relies on manual operation. A gravity ball 400 is manually placed into the valve body 100, then the gravity valve disc 300 is inserted into the valve cover 200. The gravity valve disc is then held in place by fingers, and the valve cover is inverted so that its base plate enters the valve body. Finally, a press or punch press is used to deform and rivet the upper edge 110 of the valve body 100 to the outer surface of the valve cover base plate 210, thus completing the riveting and fixing of the valve cover and valve body. This production method has the following significant drawbacks: First, it is entirely dependent on manual operation, requiring a large labor force and resulting in high labor costs; second, the riveting operation involves high output force, making it extremely easy to cause hand injuries during manual operation, resulting in very poor safety; third, the consistency of material placement is difficult to guarantee, leading to inconsistent dimensional accuracy and assembly quality of the riveted products and a low product qualification rate. Summary of the Invention

[0003] The purpose of this invention is to provide a fully automatic assembly and riveting equipment for fuel spill valves, thereby realizing the automated production of fuel spill valves and solving the problems of high cost, poor safety, and low product consistency of manual assembly and riveting in the prior art.

[0004] The technical solution of this invention: A fully automatic assembly and riveting device for a fuel spill valve, comprising a machine base and a turntable rotatably mounted on the machine base. Several carriers are spaced apart circumferentially on the turntable. A valve cover feeding unit, a gravity valve disc feeding unit, a gravity ball feeding unit, a valve body feeding unit, and a valve body-valve cover riveting unit are sequentially arranged circumferentially around the turntable. Each carrier has a workpiece cavity for accommodating the workpiece. A supporting carrier is located in the center of the workpiece cavity. The supporting carrier is suspended and its bottom abuts against a first elastic element. The upper surface of the supporting carrier supports the valve cover base and has a positioning hole in its center for inserting the gravity valve stem of the valve cover. A pressure-bearing surface is located on the outer periphery of the workpiece cavity around the supporting carrier. This pressure-bearing surface can contact the upper circumferential edge of the valve body. The upper surface of the supporting carrier is higher than... The following configurations are provided: The valve cover feeding unit transports the inverted valve cover to the workpiece cavity of the carrier, inserts the gravity valve stem of the valve cover downwards into the positioning hole, and places the valve cover's base face down on the support carrier; the gravity valve disc feeding unit transports the inverted gravity valve disc to the workpiece cavity of the carrier and places it inside the valve cover; the gravity ball feeding unit transports the gravity ball to the workpiece cavity of the carrier and places it above the gravity valve disc inside the valve cover; the valve body feeding unit transports the inverted valve body to the workpiece cavity of the carrier and inverts it onto the valve cover; the valve body-valve cover riveting unit presses down on the valve body, causing the support carrier and its valve body and valve cover to move downwards synchronously until the upper ring edge of the valve body is pressed against the pressure surface, thereby riveting the upper ring edge to the outer edge of the valve cover base.

[0005] By adopting the above technical solution, a fully automated assembly system for fuel spill valves is constructed by integrating the turntable and valve cover feeding unit, gravity valve disc feeding unit, gravity ball feeding unit, valve body feeding unit, and valve body-valve cover riveting unit. This completely replaces the traditional manual step-by-step assembly mode, effectively avoids problems such as low efficiency and inconsistent actions during manual operation, and significantly improves overall production efficiency.

[0006] By setting a support carrier with positioning holes in the middle of the workpiece cavity of the carrier, when the valve cover is transported to the carrier, the gravity valve stem can be accurately inserted into the positioning hole, and the valve cover base is placed on the upper end face of the support carrier, realizing the positioning of the valve cover in the carrier, providing a precise benchmark for the subsequent assembly of the gravity valve disc, gravity ball and valve body; the first elastic element at the bottom of the support carrier realizes elastic suspension support, and in conjunction with the pressure bearing surface on the outer periphery of the workpiece cavity, when the valve body is subjected to downward pressure during the riveting process, the support carrier can move down smoothly and synchronously with the valve body and valve cover until the upper ring edge of the valve body abuts and is squeezed against the pressure bearing surface. The elastic support structure can buffer the riveting impact force and avoid deformation of the workpiece due to uneven force during the riveting process. At the same time, the fit between the pressure bearing surface and the upper ring edge of the valve body ensures that the upper ring edge of the valve body is tightly connected to the valve cover after riveting, improving the product assembly accuracy and structural stability.

[0007] A further feature of the present invention is that the carrier includes a base and a fixed carrier mounted on the base. The fixed carrier has the workpiece cavity at its upper end. The supporting carrier is slidably disposed inside the fixed carrier. The first elastic element is housed in the fixed carrier and its two ends abut against the bottom wall of the supporting carrier and the base, respectively. The outer ring of the pressure-bearing surface is inclined inward to guide the upper ring edge of the valve body to bend inward.

[0008] With the above-mentioned further configuration, the support carrier is slidably located inside the fixed carrier, forming a vertical guide structure, which effectively restricts the offset of the support carrier and ensures that the support carrier only moves vertically up and down; the outer ring of the pressure-bearing surface is designed as an inwardly inclined structure. During the riveting process, after the upper ring edge of the valve body contacts the inclined pressure-bearing surface, the inclined surface can generate an inward guiding force, guiding the upper ring edge of the valve body to bend evenly inward, avoiding local over-bending or under-bending, ensuring that the connection surface between the valve body and the valve cover is flat and reliable after riveting, and meeting the sealing performance requirements of the fuel spill valve.

[0009] A further provision of the present invention: the valve cover feeding unit includes a valve cover vibrating feeder, a valve cover feeding rail, and a first clamping mechanism. The upstream end of the valve cover feeding rail is connected to the outlet of the valve cover vibrating feeder, and the downstream end is connected to the valve cover picking position. The valve cover feeding rail is provided with a valve stem channel, which allows multiple inverted valve covers to be inserted vertically and pass through sequentially. Support rail surfaces are provided on both sides of the upper end of the valve stem channel. A rail cover plate is provided above the valve stem channel. The rail cover plate and the support rail surface cooperate to form a chassis rail groove. The chassis rail groove allows the chassis side of the inverted valve cover to be inserted and pass through. The upper end of the valve cover picking position is open. The first clamping mechanism is used to clamp and transfer the inverted valve cover at the valve cover picking position to the carrier.

[0010] With the above-mentioned further configuration, the valve covers are automatically sorted and fed through a vibrating material tray. The vibrating material tray can sort the randomly stacked valve covers into an inverted state (with the gravity valve stem facing down) through vibration, and then transport them in an orderly manner to the valve cover loading rail. By setting valve stem channels and chassis rail grooves on the loading rail, the valve stem channels can accommodate the gravity valve stems of the inverted valve covers and guide them to pass upright. The chassis rail grooves can engage the sides of the valve cover chassis, restricting the valve covers from flipping and shifting during the transportation process, ensuring that the valve covers always remain in an inverted position with the gravity valve stems upright, thus ensuring the accurate insertion of the valve covers into the carrier positioning holes. The upper end of the valve cover picking position is open, which makes it convenient for the grippers of the first clamping mechanism to grab the valve covers from above or the side, avoiding interference with the loading rail during the picking process, improving the efficiency and stability of valve cover loading, and ensuring that the valve covers can be quickly and accurately transferred into the carrier.

[0011] A further provision of the present invention: the gravity valve disc feeding unit includes a valve disc vibrating feed plate, a valve disc feeding rail, and a second clamping mechanism. The upstream end of the valve disc feeding rail is connected to the outlet of the valve disc vibrating feed plate, and the downstream end is connected to the valve disc picking position. The valve disc feeding rail is provided with a valve disc channel, which allows multiple horizontally positioned gravity valve discs to pass through sequentially. The upper end of the valve disc picking position is open. The second clamping mechanism is used to flip the horizontally positioned gravity valve disc at the valve disc picking position to an upright position and clamp and transfer it into the valve cover on the carrier.

[0012] By further configuring the above-mentioned components, the automatic and orderly feeding of gravity valve discs is achieved through the cooperation of the valve disc vibrating feeder and the valve disc feeding rail. The vibrating feeder can organize the disordered gravity valve discs into a lying position and transport them sequentially to the valve disc picking position through the valve disc channel, avoiding material jamming or disordered feeding and improving feeding stability. The second clamping mechanism realizes the flipping and transfer of the lying gravity valve discs. The clamping mechanism first clamps the lying valve disc at the valve disc picking position, and then flips it into an upright position, ensuring that the gravity valve disc is placed in the valve cover in the carrier with the correct posture, meeting the assembly posture requirements of the gravity valve disc in the valve cover. The integrated design of flipping and transfer eliminates the need for an additional flipping device, simplifying the equipment structure. At the same time, the precise clamping and flipping action of the clamping mechanism can prevent the gravity valve disc from falling or being damaged during the transfer process, improving the accuracy and efficiency of valve disc assembly.

[0013] A further embodiment of the present invention: the gravity ball feeding unit includes a gravity ball vibrating cylinder, a gravity ball discharge rail, a ball receiving component, a ball feeding seat, and a pushing mechanism. The upper end of the gravity ball discharge rail is connected to the outlet of the gravity ball vibrating cylinder, and the lower end is connected to the ball receiving component. The ball receiving component has a receiving port for a single gravity ball to enter and exit. The ball feeding seat is located above the turntable and has a discharge port for a single gravity ball to fall. The ball receiving component is horizontally slidably mounted on the ball feeding seat. The pushing mechanism pushes the ball receiving component to slide. When the receiving port of the ball receiving component is aligned with the lower end of the gravity ball discharge rail, it is used to catch the falling gravity ball. When the ball receiving component slides, its upper receiving port is aligned with the discharge port of the ball feeding seat, and the gravity ball falls from the discharge port onto the inverted gravity valve disc on the lower carrier.

[0014] With the above-mentioned further configuration, automatic feeding of gravity balls is achieved through a vibrating ball feeder. The vibrating feeder can arrange multiple gravity balls in an orderly manner and guide them to fall through the gravity ball discharge rail, ensuring the continuity of gravity ball feeding. By setting a sliding fit between the ball receiving component and the ball loading seat, and in conjunction with the drive of the pushing mechanism, the gravity balls are moved in stages. When the ball receiving port of the ball receiving component is aligned with the lower end of the discharge rail, it can accurately catch a single falling gravity ball, preventing multiple gravity balls from falling simultaneously. This can cause material jamming. When the pushing mechanism pushes the ball receiving part to slide to align with the ball receiving port and the ball loading seat outlet, the gravity ball can fall from the outlet into the valve cover of the lower carrier under the action of gravity, achieving precise feeding of the gravity ball. The entire feeding process achieves orderly "receiving-transferring-falling" actions through sliding switching, avoiding blockage or feeding deviation of the gravity ball during the feeding process, ensuring that a single gravity ball is accurately placed above the gravity valve disc in the valve cover, and improving the reliability of the gravity ball assembly.

[0015] A further feature of the present invention is that the gravity ball feeding unit also includes a first through-beam sensor and a second through-beam sensor. The first through-beam sensor corresponds to the lower end of the gravity ball discharge rail, and the second through-beam sensor corresponds to the discharge port. When the ball receiving port of the ball receiving component is aligned with the lower end of the gravity ball discharge rail and receives the gravity ball, the first through-beam sensor detects that the gravity ball is in place and drives the pushing mechanism to move the ball receiving component towards the discharge port. When the second through-beam sensor detects that the gravity ball has fallen from the discharge port, it drives the pushing mechanism to move the ball receiving component back to its original position.

[0016] By further configuring the above-mentioned components, a first and second pair of photoelectric sensors are added to the gravity ball feeding unit to construct an automated detection and control closed loop. The first pair of photoelectric sensors is located at the lower end of the discharge rail and can detect in real time whether the ball receiving component has successfully received the gravity ball. When the gravity ball is detected to be in place, a signal is automatically sent to drive the pushing mechanism to move the ball receiving component towards the discharge port, ensuring that the gravity ball is promptly transferred after receiving it. The second pair of photoelectric sensors is located at the discharge port and can detect in real time whether the gravity ball has successfully fallen from the discharge port. When the falling is detected to be complete, a signal is automatically sent to drive the pushing mechanism to move the ball receiving component to slide and reset, preparing for the next receiving action. Through the precise detection and signal feedback of the dual sensors, the gravity ball feeding process is automated without manual intervention, effectively avoiding problems such as missed ball supply, excessive ball supply, or incomplete transfer, improving the automation level and accuracy of the feeding process, and ensuring the continuity and stability of the assembly process.

[0017] A further embodiment of the present invention: the valve body feeding unit includes a valve body vibrating feeder, a valve body feeding rail, and a third clamping mechanism. The upstream end of the valve body feeding rail is connected to the outlet of the valve body vibrating feeder, and the downstream end is connected to the valve body picking position. The valve body feeding rail is provided with a valve body channel, which can be used to sequentially transport multiple inverted valve bodies. The downstream end of the valve body feeding rail is provided with a correction adjustment component for correcting the valve bodies passing through. The correction adjustment component has a correction surface above the valve body channel. The correction surface has a "Λ" shaped structure adapted to the conical bottom surface of the inverted valve body. The upper end of the valve body picking position is open. The third clamping mechanism is used to clamp and transfer the corrected inverted valve body at the valve body picking position to the carrier and invert it onto the valve cover.

[0018] With the above-mentioned further configuration, the valve body is automatically sorted and fed through a vibrating material tray. The vibrating material tray can organize the messy valve bodies into an inverted state and transport them in an orderly manner to the valve body picking position through the valve body channel, eliminating the need for manual tray placement and reducing labor intensity. By setting a correction and adjustment component at the downstream end of the valve body upper rail, and designing the correction surface as a "Λ"-shaped structure adapted to the conical bottom surface of the inverted valve body, when the valve body is transported to the correction and adjustment component through the valve body channel, the "Λ"-shaped correction surface can fit against the conical bottom surface of the valve body, automatically correcting the angle position of the valve body and ensuring that the valve body maintains the correct posture at the picking position. The third clamping mechanism picks up the corrected valve body and transfers it to the carrier, ensuring that when the valve body is inverted on the valve cover, connection problems caused by valve body posture deviation are avoided, laying a good foundation for the subsequent riveting process and improving the assembly accuracy of the valve body and the overall quality of the product.

[0019] A further provision of the present invention: the valve body-valve cover riveting unit includes a riveting head and a pneumatic-hydraulic booster cylinder. The riveting head has an annular head that can be inserted into the workpiece cavity. The annular head contacts the bottom surface of the outer periphery of the inverted valve body. Through the cooperation of the annular head with the pressure-bearing surface, the upper edge of the valve body is riveted to the outer edge of the valve cover base.

[0020] With the above-mentioned further configuration, a pneumatic-hydraulic booster cylinder is used to power the riveting head. The pneumatic-hydraulic booster cylinder can output a stable and adjustable riveting force, which can precisely adjust the riveting force according to the requirements of fuel spill valve workpieces of different specifications and materials, meeting diverse production needs. The riveting head is designed with a structure with an annular pressure head. During riveting, the annular pressure head can be inserted into the workpiece cavity of the carrier and make uniform contact with the bottom surface of the outer periphery of the inverted valve body. The downward pressure applied by the annular pressure head, in conjunction with the pressure-bearing surface of the carrier, causes the upper ring edge of the valve body to be riveted to the upper surface of the outer edge of the valve cover chassis under pressure. The cooperation between the annular pressure head and the pressure-bearing surface ensures that the riveting force is evenly applied to the entire circumference of the upper ring edge of the valve body, avoiding deformation or weak connection caused by uneven local force, ensuring high connection strength between the valve body and the valve cover after riveting, and meeting the usage requirements of the fuel spill valve.

[0021] A further feature of the present invention is that the carrier is slidably mounted on the turntable via a support column, and a second elastic element is provided between the carrier and the upper surface of the turntable. The valve body-valve cover riveting unit includes a pressure-bearing seat, which is located below the turntable. When the carrier rotates to the valve body-valve cover riveting position, the support column is positioned above the pressure-bearing seat. The pneumatic-hydraulic booster cylinder drives the riveting head downward, which can cause the carrier to compress the second elastic element and move downward until the support column abuts against the pressure-bearing seat to form support.

[0022] By further configuring the above-mentioned components, the carrier is slidably mounted on the turntable and a second elastic element is provided. During riveting, the second elastic element is compressed, allowing the entire carrier to move downward with the riveting force until the support column abuts against the bearing seat to form support. This avoids the riveting force acting directly on the turntable, which could cause deformation and extend the service life of the equipment.

[0023] A further feature of the present invention includes a side-tipping valve discharge unit, which includes a fourth clamping mechanism and an inclined product discharge rail. The fourth clamping mechanism is used to clamp and transfer the side-tipping valve assembled on the carrier to the product discharge rail.

[0024] By further configuring the above-mentioned components and adding a side-tipping valve discharge unit, the automatic unloading of workpieces after assembly and riveting is achieved. The fourth clamping mechanism can accurately grasp the finished product side-tipping valve in the carrier, avoiding product damage caused by improper operation during manual handling. Through the inclined discharge rail, the finished workpiece can slide down to the collection box under its own gravity, eliminating the need for an additional conveying power device and simplifying the equipment structure. The discharge unit enables the equipment to form a fully automated closed-loop production line of "loading-assembly-riveting-unloading", eliminating the need for manual intervention in the transfer and collection of workpieces, further improving production efficiency, reducing labor costs, and avoiding product contamination or damage caused by manual handling, thus ensuring the stability of finished product quality.

Detailed Implementation

[0045] The technical solutions in this embodiment will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0046] like Figure 1-18 As shown, the present invention discloses a fully automatic assembly and riveting equipment for a fuel spill valve, comprising a machine base 1 and a turntable 2 rotatably mounted on the machine base 1. Several carriers 3 are arranged at intervals along the circumference of the turntable 2. Around the turntable 2, a valve cover feeding unit 4, a gravity valve disc feeding unit 5, a gravity ball feeding unit 6, a valve body feeding unit 7, a valve body-valve cover riveting unit 8, and a spill valve discharging unit 9 are arranged sequentially along the circumference. The turntable is rotatably mounted in the middle of the machine base via bearings and is driven by a servo motor to achieve intermittent rotation. The rotation angle of the turntable matches the interval angle of each workstation, ensuring that the carriers can accurately stop at the corresponding workstations of each functional unit. Each unit corresponds to the turntable, forming a closed-loop automated production line.

[0047] The carrier includes a base 34, a fixed carrier 35, a supporting carrier 32, a first elastic element 33, a supporting column 36, and a second elastic element 37. The base 34 is assembled on the turntable 2 via several supporting columns 36, and the base 34 and the supporting columns 36 form a sliding fit to ensure that the base can be raised and lowered vertically along the supporting columns. The second elastic element 37 is connected between the base 34 and the turntable 2 to provide elastic support for the base 34. The fixed carrier 35 is fixed or integrally disposed on the upper surface of the base 34, and the upper end of the fixed carrier 35 is provided with a workpiece cavity 31. The supporting carrier 32 is slidably disposed inside the workpiece cavity 31 of the fixed carrier 35, and the supporting carrier is clearance-fitted with the inner wall of the workpiece cavity to ensure that the supporting carrier can only slide vertically. The first elastic element 33 is housed in the bottom of the fixed carrier 35, and its two ends abut against the bottom wall of the supporting carrier 32 and the base 34, respectively, to elastically support the supporting carrier 32 and keep the supporting carrier 32 in a suspended state. The upper surface of the support carrier 32 is used to support the valve cover chassis, and a positioning hole 321 is provided in the middle for the gravity valve rod of the valve cover to be inserted. The size of the positioning hole is adapted to the outer diameter of the gravity valve rod of the valve cover to ensure that the gravity valve rod can be accurately positioned after being inserted into the positioning hole. The bottom wall of the workpiece cavity 31 is provided with a pressure bearing surface 311 on the outer periphery of the support carrier 32. The pressure bearing surface 311 can contact the upper ring edge of the valve body. The upper surface of the support carrier 32 is set higher than the pressure bearing surface 311 to ensure that when the valve body is upside down on the valve cover in the unriveted state, the upper ring edge of the valve body will not contact the pressure bearing surface, thus reserving stroke for the riveting process. The outer ring of the pressure bearing surface 311 is inclined inward to guide the upper ring edge of the valve body to bend inward. The above-mentioned elastic element is a spring.

[0048] The valve cover feeding unit 4 is used to transport the inverted valve cover to the workpiece cavity 31 of the carrier 3, and to insert the gravity valve stem of the valve cover downward into the positioning hole 321, with the bottom of the valve cover placed face down on the support carrier 32; the valve cover feeding unit 4 includes a valve cover vibrating material plate 41, a valve cover feeding rail 42 and a first clamping mechanism 43. The valve cover vibrating material plate is fixed to one side of the machine and uses electromagnetic vibration to organize the randomly stacked valve covers into an inverted state (gravity valve stem downward) through the force generated by the vibration, and to transport them in an orderly manner to the valve cover feeding rail; the upstream end of the valve cover feeding rail 42 is connected to the outlet of the valve cover vibrating material plate 41, and the downstream end is connected to the valve cover picking position 44. The valve cover feeding rail 42 is provided with a valve stem channel 421, which allows multiple inverted valve covers to be inserted vertically and pass through in sequence. The upper end of the valve stem channel 421 is provided with support rail surfaces 422 on both sides. A track cover plate 423 is installed above the rod channel 421. The track cover plate 423 and the support rail surface 422 cooperate to form a chassis rail groove 424. The chassis rail groove 424 allows the side of the inverted valve cover to be inserted and pass through, ensuring that the valve cover remains inverted and the gravity valve rod is upright during the conveying process. The upper end of the valve cover picking position 44 is open, which facilitates the first clamping mechanism to grab the valve cover. The first clamping mechanism is set above the valve cover picking position and includes a clamping part and a driving part. The clamping part adopts a pneumatic gripper, which can realize the opening and closing action and is used to clamp the valve cover chassis or gravity valve rod. The driving part adopts a combination of linear module and rotary cylinder, which can drive the clamping part to realize up and down and left and right movement. After grabbing the inverted valve cover at the valve cover picking position, it is transferred to the carrier on the turntable, so that the gravity valve rod of the valve cover is inserted into the positioning hole of the carrier support carrier, and the valve cover chassis is placed stably on the upper end surface of the support carrier.

[0049] The gravity valve disc feeding unit 5 is used to transport the inverted gravity valve discs to the workpiece cavity 31 of the carrier 3 and place them inside the valve cover. The gravity valve disc feeding unit 5 includes a valve disc vibrating feed plate 51, a valve disc feeding rail 52, and a second clamping mechanism 53. The valve disc vibrating feed plate is fixed to one side of the machine base and uses electromagnetic vibration to arrange the disordered gravity valve discs into a lying position, and then transports them to the valve disc feeding rail in sequence. The upstream end of the valve disc feeding rail 52 is connected to the outlet of the valve disc vibrating feed plate 51, and the downstream end is connected to the valve disc picking position 54. The valve disc feeding rail 52 is provided with a valve disc channel 521, which can accommodate multiple lying valve discs. The gravity valve discs in the neutral position pass through sequentially; the upper end of the valve disc picking position 54 is open to facilitate the gripping of the second clamping mechanism; the second clamping mechanism is set above the valve disc picking position and includes a clamping part, a rotating part and a driving part. The clamping part adopts a pneumatic gripper that can clamp both ends of the gravity valve disc. The rotating part adopts a rotary cylinder connected to the clamping part, which can drive the clamping part to achieve a 90° rotation, turning the lying gravity valve disc into an upright position. The driving part adopts a linear module that can drive the clamping part and the rotating part to achieve up-down and left-right movements, transferring the upright gravity valve disc into the carrier on the turntable and placing it in the corresponding position inside the valve cover.

[0050] The gravity ball feeding unit 6 is used to transport gravity balls to the workpiece cavity 31 of the carrier 3 and place them above the gravity valve disc located inside the valve cover. The gravity ball feeding unit 6 includes a gravity ball vibrating cylinder 61, a gravity ball discharge rail 62, a ball receiving component 63, a ball feeding seat 64, and a pushing mechanism 65. The gravity ball vibrating cylinder is fixed to one side of the machine base and uses electromagnetic vibration to arrange multiple gravity balls in an orderly manner and guide them to fall through the gravity ball discharge rail. The upper end of the gravity ball discharge rail 62 is connected to the outlet of the gravity ball vibrating cylinder 61. The lower end connects to the ball receiving component 63, and the inner diameter of the discharge rail is slightly larger than the diameter of the gravity ball to ensure that a single gravity ball can fall smoothly. The ball receiving component 63 is provided with a receiving port 631 for a single gravity ball to enter and exit. The ball loading seat 64 is located above the turntable 2 and has a discharge port 641 for a single gravity ball to fall. The ball receiving component 63 is horizontally slidably mounted on the ball loading seat 64, which is provided with a horizontal guide groove. The bottom of the ball receiving component is provided with a slider that matches the guide groove to ensure that the ball receiving component can move smoothly along the guide groove. Stable sliding; the pushing mechanism is connected to the ball receiving component and is driven by a cylinder, which can push the ball receiving component to slide back and forth along the guide groove to realize the alignment switching between the ball receiving port and the lower end of the gravity ball discharge rail and the discharge port of the ball loading seat; the gravity ball loading unit 6 also includes a first through-beam sensor and a second through-beam sensor. The first through-beam sensor corresponds to the lower end of the gravity ball discharge rail and consists of a transmitter and a receiver. When the ball receiving port of the ball receiving component is aligned with the lower end of the discharge rail and receives the gravity ball, the gravity ball blocks the sensor light, and the first through-beam sensor detects... Once the gravity ball is in position, a signal is sent to the control system, driving the pushing mechanism to slide the ball receiving component towards the discharge port. The second through-beam sensor, which corresponds to the discharge port of the ball loading seat, consists of a transmitter and a receiver. When the ball receiving port of the ball receiving component is aligned with the discharge port, the gravity ball falls from the discharge port onto the inverted gravity valve disc on the lower carrier 3. The sensor light is restored, and the second through-beam sensor detects that the gravity ball has fallen completely. It then sends a signal to the control system, driving the pushing mechanism to slide the ball receiving component back to its original position, preparing for the next receiving action.

[0051] The valve body feeding unit 7 is used to transport the inverted valve body to the workpiece cavity 31 of the carrier 3 and place the valve body upside down on the valve cover. The valve body feeding unit 7 includes a valve body vibrating feeder 71, a valve body feeding rail 72, and a third clamping mechanism 73. The valve body vibrating feeder is fixed to one side of the machine and uses electromagnetic vibration to organize the messy valve bodies into an inverted state, and then transports them sequentially to the valve body picking position via the valve body feeding rail. The upstream end of the valve body feeding rail 72 is connected to the outlet of the valve body vibrating feeder 71, and the downstream end is connected to the valve body picking position 74. The valve body feeding rail 72 is provided with a valve body channel 721, which can be used to transport multiple inverted valve bodies sequentially. The downstream end of the valve body feeding rail 72 is provided with a correction and adjustment component 75, which is detachably assembled to the valve body feeding rail by bolts, making it easy to replace according to different specifications of valve bodies. 75 has a correction surface 751 above the valve body channel 721. The correction surface 751 has a "Λ" shaped structure that matches the conical bottom surface of the inverted valve body. When the valve body is transported to the correction adjustment component through the valve body channel, the conical bottom surface of the valve body fits with the "Λ" shaped correction surface. The correction adjustment component can automatically adjust the angle position of the valve body to ensure that the valve body maintains the correct posture at the valve body picking position. The valve body picking position 74 is open at the top to facilitate the third clamping mechanism to grab the valve body. The third clamping mechanism is set above the valve body picking position. Its structure is similar to the first clamping mechanism, including a clamping part and a driving part. The clamping part adopts a pneumatic gripper that can clamp the outer periphery of the valve body. The driving part adopts a linear module that can drive the clamping part to move up and down and left and right. After grabbing the inverted valve body at the valve body picking position after correction, it is transferred to the carrier on the turntable and inverted onto the valve cover.

[0052] The valve body-valve cover riveting unit 8 is used to press down the valve body, causing the support carrier 32 and the valve body and valve cover on it to move down synchronously until the upper ring edge of the valve body is pressed against the pressure surface 311, thereby riveting the upper ring edge to the outer edge of the valve cover base. The valve body-valve cover riveting unit 8 includes a riveting head 81, a pneumatic-hydraulic booster cylinder 82, and a bracket. The bracket is fixed above the machine base and located at the corresponding work position on the turntable. The pneumatic-hydraulic booster cylinder is fixed to the top of the bracket, with its output end facing downward and connected to the riveting head. The riveting head is located below the pneumatic-hydraulic booster cylinder and above the workpiece cavity of the carrier. The lower end of the riveting head has an annular pressing head 811 that can be inserted into the workpiece cavity 31. The forming head 811 contacts the bottom surface of the inverted valve body. A pressure sensor is provided between the forming head and the output end of the pneumatic-hydraulic booster cylinder. The pressure sensor is electrically connected to the pneumatic-hydraulic booster cylinder and the control system to detect the pressure value in real time during the forming process and feed the signal back to the control system. When the pressure value reaches the set threshold, the control system controls the pneumatic-hydraulic booster cylinder to stop pressing down to avoid excessive forming. At the same time, a guide structure is provided between the forming head and the bracket, including a guide post and a guide sleeve, to ensure that the forming head remains vertical during the up and down movement and to avoid deviation. The annular forming head 811 cooperates with the pressure bearing surface 311 to form the upper edge of the valve body on the outer edge of the valve cover base. The carrier 3 is slidably mounted on the turntable 2 via a support column 36. The base 34 of the carrier 3 is fixedly or integrally connected to the support column 36, and a second elastic element 37 is provided between the base 34 of the carrier 3 and the upper surface of the turntable 2. The valve body-valve cover riveting unit 8 includes a pressure seat 83 located below the turntable 2. When the carrier 3 rotates to the valve body-valve cover riveting position, the support column 36 is positioned above the pressure seat. The pneumatic-hydraulic booster cylinder 82 drives the riveting head 81 downward, which compresses the second elastic element 37 and moves the carrier 3 downward until the support column 36 abuts against the pressure seat 83 to form support. The base 34 of the carrier 3 is also slidably engaged with guide holes on the turntable via several guide rods. The guide rods further enhance the stability and accuracy of the carrier's movement on the turntable, preventing the carrier from shaking or deviating during rotation and riveting.

[0053] The side-tipping valve discharge unit 9 includes a fourth clamping mechanism 91 and an inclined product discharge rail 92. The fourth clamping mechanism 91 is positioned above the discharge station of the turntable. Its structure is similar to that of the first clamping mechanism, including a clamping part and a driving part. The clamping part uses pneumatic grippers to clamp the outer periphery of the assembled side-tipping valve. The driving part uses a linear module to drive the clamping part to move up and down and left and right, grabbing the finished side-tipping valve in the carrier and transferring it to the product discharge rail. The product discharge rail is inclined and fixed to one side of the machine. Its upper end corresponds to the transfer position of the fourth clamping mechanism, and its lower end extends to the top of the collection box to ensure that the finished workpiece can slide smoothly down along the discharge rail.

[0054] The working principle of the fully automatic fuel side-tipping valve assembly and riveting equipment of the present invention is as follows:

[0055] After the equipment is started, each vibrating material plate (valve cover vibrating material plate, valve disc vibrating material plate, valve body vibrating material plate) and gravity ball vibrating material cylinder start working, respectively arranging the valve cover, gravity valve disc, valve body and gravity ball into the set posture, and conveying them to the picking position through the corresponding feeding rail;

[0056] The turntable rotates intermittently under the drive of the servo motor. When the carrier rotates to the corresponding station of the valve cover loading unit, the turntable stops rotating. The first clamping mechanism grabs the inverted valve cover at the valve cover picking position and moves it into the carrier, so that the valve cover gravity valve rod is inserted into the positioning hole of the support carrier. The valve cover base is placed on the upper end face of the support carrier to complete the valve cover loading.

[0057] The turntable continues to rotate, sending the carrier with the valve cover to the corresponding station of the gravity valve disc feeding unit. The second clamping mechanism grabs the lying gravity valve disc at the valve disc picking position, flips it to an upright state, and then moves it into the valve cover to complete the gravity valve disc feeding.

[0058] The turntable continues to rotate, delivering the carrier containing the valve cover and gravity valve disc to the corresponding station of the gravity ball feeding unit. The gravity ball output from the gravity ball vibrating cylinder falls down the discharge rail to the ball receiving port of the ball receiving component. After the first through-beam sensor detects that the gravity ball has arrived, the pushing mechanism drives the ball receiving component to slide, so that the ball receiving port is connected to the discharge port of the ball feeding seat. The gravity ball falls from the discharge port to the gravity valve disc inside the valve cover. After the second through-beam sensor detects that the gravity ball has finished falling, the pushing mechanism drives the ball receiving component to reset, completing the gravity ball feeding.

[0059] The turntable continues to rotate, sending the carrier containing the valve cover, gravity valve disc and gravity ball to the corresponding station of the valve body loading unit. The third clamping mechanism grabs the inverted valve body after correction at the valve body picking position, moves it into the carrier and inverts it on the valve cover to complete the valve body loading.

[0060] The turntable continues to rotate, delivering the carrier containing all components to the corresponding station of the valve body-valve cover riveting unit. The pneumatic-hydraulic booster cylinder drives the riveting head to move downwards. The annular head contacts the bottom surface of the valve body and applies pressure. Under the pressure, the support carrier drives the valve cover and valve body to move downwards synchronously until the upper edge of the valve body is pressed against the pressure surface. Under the guidance of the pressure and the pressure surface, the upper edge of the valve body bends inwards and is riveted to the upper surface of the outer edge of the valve cover chassis. After the pressure sensor detects that the pressure has reached the set threshold, the pneumatic-hydraulic booster cylinder drives the riveting head to reset, completing the riveting process.

[0061] The turntable continues to rotate, sending the assembled and riveted workpiece to the corresponding station of the side-tipping valve discharge unit. The fourth clamping mechanism grabs the finished workpiece and moves it to the discharge rail. The workpiece slides down the discharge rail to the collection box, completing the unloading.

[0062] The turntable continues to rotate, and the empty vehicle returns to the corresponding station of the valve cover loading unit to start the next round of assembly process. This cycle repeats to achieve fully automatic assembly and riveting of the fuel spill valve.

[0063] This invention integrates a turntable with multiple feeding, riveting, and discharging units to construct a complete fully automated assembly and riveting production line for fuel spill valves. It achieves fully automated feeding, assembly, and riveting of the valve cover, gravity valve disc, gravity ball, and valve body, completely replacing manual operation and significantly improving production efficiency. By setting up a precise positioning structure and elastic support structure within the carrier, combined with the attitude control and correction mechanisms of each feeding unit, it ensures the coaxiality of the assembled components and the riveting accuracy, preventing workpiece deformation and improving product quality. Through the cooperation of sensors and a control system, it achieves automated detection and control of each process, ensuring the continuity and stability of the production process, reducing labor costs and labor intensity, and meeting the needs of mass production.
