[0033] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments, in conjunction with the accompanying drawings, specifically illustrate the automotive water tank pressure cap assembly system of the present invention.

[0034] This embodiment provides an automotive radiator pressure cap assembly system for assembling multiple automotive radiator pressure cap parts into a finished automotive radiator pressure cap.

[0035] Figure 2 This is a schematic diagram of the automotive water tank pressure cap assembly system in an embodiment of the present invention.

[0036] like Figure 2 As shown, the automotive radiator pressure cap assembly system 200 includes a rubber pad assembly device 21, a balance valve assembly device 22, a spring assembly device 23, a top cover assembly device 24, a top cover pressing device 25, a sealing ring assembly device 26, an airtightness testing device 27, a threaded cap screen printing device 28, a threaded cap assembly device 29, a finished product stacking device 30, a conveying device 31, a storage device (not shown in the figure), an automatic feeding device (not shown in the figure), and a central control device (not shown in the figure) that controls the operation of the above devices.

[0037] The rubber gasket assembly equipment 21 is used to assemble the rubber gasket 12 into the housing 11 to obtain a semi-finished automotive radiator pressure cap. The rubber gasket assembly equipment 21 includes a housing feeding mechanism, a rubber gasket feeding mechanism, and an adsorption and clamping mechanism.

[0038] The shell feeding mechanism is used to store and output the oriented shells 11.

[0039] The rubber pad feeding mechanism is used to store and output oriented rubber pads 12.

[0040] The adsorption and gripping mechanism is used to adsorb the rubber pad 12, grip the housing 11, and assemble the rubber pad 12 into the housing 11.

[0041] Figure 3 This is a schematic diagram of the adsorption and gripping mechanism in an embodiment of the present invention.

[0042] like Figure 3 As shown, the adsorption and gripping mechanism 211 includes a rubber pad assembly support frame 2111, a three-axis moving unit 2112, an adsorption and gripping unit 2113, and a rubber pad assembly control unit (not shown in the figure).

[0043] The three-axis moving unit 2112 is mounted on the rubber pad mounting support frame 2111 and is used to move along the x-axis, y-axis and z-axis. The three-axis moving unit 2112 includes an x-axis moving component 21121, a y-axis moving component 21122 and a z-axis moving component 21123.

[0044] The x-axis moving component 21121 is mounted on the rubber pad mounting support frame 2111 and is used for movement along the x-axis. The y-axis moving component 21122 is mounted on the x-axis moving component 21121 and is used for movement along the y-axis. The z-axis moving component 21123 is mounted on the y-axis moving component and is used for movement along the z-axis.

[0045] The adsorption and gripping unit 2113 is mounted on the three-axis moving unit 2112 and includes a fixing frame 21131, a rubber pad adsorption assembly 21132, a housing gripper 21133, and a housing sensor 21134.

[0046] The fixed bracket 21131 is fixedly connected to the z-axis moving part 21123.

[0047] A rubber pad adsorption assembly 21132 is disposed on one side of the fixing frame 21131 for adsorbing the rubber pad 12. The rubber pad adsorption assembly 21132 includes floating connectors 21135 and 21136 and a vacuum generator (not shown in the figure). The vacuum generator is used to generate suction and detects whether the rubber pad 12 is adsorbed based on the magnitude of the suction.

[0048] The floating connector 21135 includes a spring (not shown in the figure) and a floating bearing 211351. The two ends of the floating connector 211321 are connected to the adsorption head 21136 and the fixed frame 21131, respectively. A corresponding spring is fitted on each floating bearing 211351.

[0049] After the adsorption head 21136 contacts the rubber pad 12, the rubber pad assembly control unit continues to control the three-axis moving unit 2112 to move downward along the z-axis by a certain distance, causing the floating connector 21135 to compress and transmit pressure to the adsorption head 21136, making the adsorption head 21136 and the rubber pad 12 in close contact. In this embodiment, after the adsorption head 21136 contacts the rubber pad 12, the floating connector 21135 can relieve the pressure of the three-axis moving unit 2112 moving downward along the z-axis, making the adsorption head 21136 and the rubber pad 12 in closer contact while preventing damage to the adsorption head 21136 or the rubber pad 12 due to excessive instantaneous force.

[0050] Figure 4 This is a schematic diagram of the adsorption head and the housing gripper in an embodiment of the present invention.

[0051] like Figure 4 As shown, the adsorption head 21136 includes a first cylinder 21137, a second cylinder 21138, and a plurality of suction holes 21139.

[0052] The second cylinder 21138 is disposed on the first cylinder 21137, and the first cylinder 21137 and the second cylinder 21138 have the same center. The diameter of the second cylinder 21138 is smaller than the inner diameter of the rubber pad 12, and the height of the second cylinder 21138 is smaller than the thickness of the rubber pad 12, so that the rubber pad 12 can be fitted onto the second cylinder 21138. On the contact surface between the first cylinder 21137 and the second cylinder 21138, a plurality of suction holes 21139 are evenly distributed along the second cylinder 21138 to generate suction to adsorb the rubber pad 12.

[0053] In this embodiment, the surface of the second cylinder 21138 that contacts the rubber pad 12 is smoothed, so that the second cylinder 21138, which is slightly smaller than the inner diameter of the rubber pad 12, can pass through the central hole of the rubber pad 12 more easily and make correct contact with the rubber pad 12.

[0054] The housing gripper 21133 is disposed on the other side of the fixing frame 21131 and is used to grip the housing 11. The housing gripper 21133 includes at least two jaws 21140, and the jaws 21140 are provided with grooves corresponding to the upper edge of the housing 11. When the housing gripper 21133 clamps, the upper edge of the housing 11 is embedded in the grooves, so that the housing gripper 21133 firmly grips the housing 11. In this embodiment, the housing gripper 2113 includes three evenly distributed jaws 21140, thereby stably gripping the housing 11.

[0055] The housing sensor 21134 is located on one side of the housing gripper 21133 and is used to detect the presence of the housing 11.

[0056] The rubber pad assembly control unit is used to control the operation of the three-axis moving unit 2112 and the adsorption clamping unit 2113, thereby realizing the assembly of the rubber pad 12.

[0057] The balancing valve assembly equipment 22 is used to assemble the balancing valve 13 onto the semi-finished automotive water tank pressure cap.

[0058] Spring assembly equipment 23 is used to assemble springs 14 onto semi-finished automotive water tank pressure caps.

[0059] The top cover assembly equipment 24 is used to assemble the top cover 15 of the semi-finished automotive water tank pressure cap.

[0060] The cover pressing equipment 25 is used to press the cover onto the semi-finished automotive water tank pressure cap with the cover already assembled.

[0061] The sealing ring assembly equipment 26 is used to assemble sealing rings on semi-finished automotive radiator pressure caps. The sealing rings include a large O-ring 16 and a small O-ring 17. In this embodiment, the inner diameter of the large O-ring 16 is larger than the inner diameter of the small O-ring 17.

[0062] Figure 5 This is a schematic diagram of the sealing ring assembly device in an embodiment of the present invention.

[0063] like Figure 5As shown, the sealing ring assembly equipment 26 includes a large O-ring feeding unit (not shown in the figure), a large O-ring detection unit 261, a large O-ring oiling unit 262, a large O-ring assembly unit 263, a large O-ring handling unit 264, a large O-ring waste box 265, a small O-ring feeding unit (not shown in the figure), a small O-ring detection unit 266, a small O-ring oiling unit 267, a small O-ring assembly unit 268, a small O-ring handling unit 269, a small O-ring waste box 260, a gripping mechanism (not shown in the figure), and a sealing ring assembly control mechanism (not shown in the figure).

[0064] The large O-ring feeding unit is used to store and output oriented large O-rings 16.

[0065] The large O-ring detection unit 261 is used to perform visual inspection on the large O-ring 16 to determine whether there is a defect in the large O-ring 16.

[0066] The large O-ring oiling unit 262 is used to apply oil to the large O-ring 16.

[0067] Figure 6 This is a schematic diagram of the large O-ring oiling unit in an embodiment of the present invention.

[0068] like Figure 6 As shown, the large O-ring oiling unit 262 includes an oiling support frame 2621, a placement slot 2622 with an opening at the top, a fixed bracket 2623, an oil injector 2624, a movable bracket 2625, an oil shield 2626, a partition 2627, and a positioning ring 2628.

[0069] The placement slot 2622 is set on the oiling support frame 2621.

[0070] The opening of the placement slot 2622 is completely covered by the partition 2627, which has a through hole that coincides with the positioning ring 2628.

[0071] A fixing bracket 2623 is disposed within the placement groove 2622 for fixing the large O-ring 16. In this embodiment, the fixing bracket is composed of multiple inverted L-shaped support columns evenly distributed along the same circumference. The column body is used to spread the large O-ring 16, and the upper stop block of the support column is used to prevent the large O-ring 16 from detaching from the support column, thereby suspending and fixing the large O-ring 16, and thus allowing the large O-ring 16 to be coated with oil.

[0072] The injector 2624 is located in the placement slot 2622 and is used to apply oil to the large O-ring 16.

[0073] The movable support 2625 is arranged facing the oiling support 2621 and is used for translation and lifting, that is, lifting in the vertical direction and translation in the parallel direction of the oiling support 2621.

[0074] An oil shield 2626 is mounted on the movable bracket 2625 to cover the opening of the placement slot 2622. In this embodiment, the inner diameter of the oil shield 2626 is slightly larger than the outer diameter of the positioning ring 2628. By completely covering the positioning ring 2628 with the oil shield 2626, the placement slot 2622 is completely sealed, preventing liquid oil mist from splashing to the outside of the equipment during oiling and ensuring the cleanliness of the equipment.

[0075] The large O-ring assembly unit 263 is used to fit the oiled large O-ring 16 onto the semi-finished automotive radiator pressure cap.

[0076] Figure 7 This is a schematic diagram of the large O-ring assembly unit in an embodiment of the present invention.

[0077] like Figure 7 As shown, the large O-ring assembly unit 263 includes an assembly support frame 2631, a fixing component 2632, a ring pushing component 2633, and a placement detection component 2634.

[0078] The fixing component 2632 is mounted on the assembly support frame 2631 and is used to fix the large O-ring 16.

[0079] The fixing component 2632 includes multiple fixing claws 26321 and a first driving member (not shown in the figure). The multiple fixing claws 26321 are evenly distributed along the same circumference for fixing the large O-ring 16. The first driving member is used to drive the fixing claws 26321 to contract inward and expand outward along the center of the circumference, as well as to move vertically up and down. This embodiment includes eight fixing claws 26321, each consisting of a claw post and a stop block, thereby forming a groove on the top of the fixing claw 26321 to fix the large O-ring 16. Specifically, the claw post is used to open the large O-ring 16, and the stop block is used to prevent the large O-ring 16 from moving downward, so that the entire large O-ring 16 is placed horizontally, which is beneficial for positioning during subsequent sealing ring installation. In this embodiment, the claw post and the stop block are integrally formed.

[0080] The push ring assembly 2633 is mounted on the assembly support frame 2631 and is used to apply a pushing force to the large O-ring 16 fixed on the fixing assembly 2632, so that the sealing ring is disengaged from the fixing assembly 2632 and fitted onto the semi-finished automotive water tank pressure cap.

[0081] The push ring assembly 2633 includes multiple push pins 26331 and a second drive member (not shown in the figure). The multiple push pins are evenly distributed along the same circumference and are used to apply thrust to the large O-ring 16. The second drive member is used to drive the push pins 26331 to contract inward and expand outward along the center of the circumference, as well as to move vertically up and down. This embodiment includes eight push pins 26331.

[0082] In this embodiment, the push column 26331 and the fixed claw 26321 are arranged alternately in sequence, and the first driving member and the second driving member are integrated into a total driving member 2635 to drive the push column 26331 and the fixed claw 26321. In this embodiment, the total driving member 2635 is mounted on the assembly support frame 2631, and the push column 26331 and the fixed claw 26321 are mounted on the total driving member 2635.

[0083] The detection component 2634 is placed on the assembly support frame 2631 and is used to detect whether the large O-ring 16 is on the fixing component 2632.

[0084] The placement detection component 2634 includes two through-beam sensors 26341, which are set on both sides of the fixed component 2632 to detect whether the large O-ring 16 is on the fixed component 2632.

[0085] The large O-ring conveying unit 264 is used to convey the defect-free large O-ring 16 from the large O-ring feeding unit to the large O-ring oiling unit 262, and from the large O-ring oiling unit 262 to the large O-ring assembly unit 263.

[0086] Figure 8 This is a schematic diagram of the large O-ring transport unit in an embodiment of the present invention.

[0087] like Figure 8 The large O-ring transport unit 264 shown includes a support frame 2641, a moving arm 2642, a sealing ring support claw 2643, an auxiliary positioning cover 2644, and a sealing ring detection sensor 2645.

[0088] The movable arm 2642 includes a horizontal moving member 26421, a vertical moving member 26422, and a movable arm drive member (not shown in the figure). The horizontal moving member 26421 is mounted on the support frame 2641, and the vertical moving member 26422 is mounted on the horizontal moving member 26421. The movable arm drive member is used to drive the horizontal moving member 26421 to move horizontally and to drive the vertical moving member 26422 to move vertically.

[0089] The sealing ring support claw 2643 is set on the end of the moving arm 2642, i.e., the vertical moving part 26422, and is used to grip the large O ring 16.

[0090] Figure 9 This is a schematic diagram of the sealing ring support claw in an embodiment of the present invention.

[0091] like Figure 9As shown, the sealing ring support claw 2643 includes a plurality of single claws 26431 evenly distributed along the circumference. Each single claw 26431 includes an opening post 264311 and a limiting block 264312. The limiting block 264312 is disposed on the opening post 264311, and in this embodiment, the limiting block 264312 and the opening post 264311 are integrally formed. In this embodiment, the sealing ring support claw 2643 includes six single claws 26431.

[0092] When the sealing ring support claw 2643 expands outward, the expansion column 264311 applies force to the large O-ring 16 from within, and the limiting block 264312 abuts against the large O-ring 16 to prevent it from moving towards the upper end of the single claw 26431, thus ensuring that the sealing ring support claw 2643 firmly grasps the large O-ring 16. When the sealing ring support claw 2643 retracts inward, the expansion column 264311 does not apply force to the large O-ring 16, allowing the sealing ring support claw 2643 to lower the large O-ring 16.

[0093] An auxiliary positioning cover 2644 is mounted on the vertical moving member 26422, covering the sealing ring support claw 2643; that is, the sealing ring support claw 2643 is positioned inside the auxiliary positioning cover 2644. In this embodiment, the dimensions of the auxiliary positioning cover 2644 match a specific groove on the positioning ring 2628. When the large O-ring 16 is moved to the large O-ring oiling unit 262 by the large O-ring transport unit 264, the lower edge of the auxiliary positioning cover 2644 is embedded in the specific groove, allowing the large O-ring 16 to accurately align with the fixed bracket 2623.

[0094] A sealing ring detection sensor 2645 is mounted on the vertical moving part 26422 to detect whether the sealing ring support claw 2643 has gripped the large O-ring 16. When the sealing ring detection sensor 2645 detects that the sealing ring support claw 2643 has not gripped the large O-ring 16, the sealing ring assembly control mechanism controls the moving arm 2642 to move and controls the sealing ring support claw 2643 to re-grip the large O-ring 16.

[0095] The large O-ring waste box 265 is used to store the large O-rings 16 that are judged to be defective by the large O-ring detection unit 261.

[0096] The small O-ring feeding unit and the large O-ring feeding unit have the same structure and function.

The small O-ring oiling unit 267 and the large O-ring oiling unit 262 have the same structure and function. The small O-ring assembly unit 268 and the large O-ring assembly unit 263 have the same structure and function. The small O-ring handling unit 269 and the large O-ring handling unit 264 have the same structure and function. The small O-ring waste box 260 and the large O-ring waste box 265 have the same structure and function. These will not be repeated here.

[0097] The gripping mechanism is used to transport the semi-finished automotive radiator pressure cap from a designated location to the large O-ring assembly unit 263 and the small O-ring assembly unit 267, and to transport the semi-finished automotive radiator pressure cap with sealing rings from the large O-ring assembly unit 263 and the small O-ring assembly unit 267 to the designated location.

[0111] The gripper assembly 30122 is used to grip the uppermost empty finished product rack 3011 in the finished product rack stack and place it on the stacking unit 3013. The gripper assembly 30122 is located above the support assembly 30121 and includes a rack gripper 301221, a rack gripper translation cylinder (not shown in the figure), and a rack gripper lifting cylinder (not shown in the figure).

[0112] The material rack gripper 301221 is used to grip empty finished product racks 3011. The material rack gripper translation cylinder is used to move the material rack gripper 301221 horizontally. The material rack gripper lifting cylinder is used to move the material rack gripper 301221 vertically up and down.

[0113] The stacking unit 3013 is used to support empty finished product racks 3011 and stack finished product racks 3011 filled with finished automotive radiator pressure caps at the bottom of the finished product rack stack. The stacking unit 3013 is arranged side by side with the handle assembly 30122 and includes a rack handle 30131, a rack handle translation cylinder (not shown in the figure), and a rack handle lifting cylinder (not shown in the figure).

[0114] The material rack support 30131 is used to support the finished material rack 3011 gripped by the material rack gripper 301221. The material rack support translation cylinder is used to move the material rack support 30131 horizontally. The material rack support lifting cylinder is used to move the material rack support 30131 vertically.

[0115] The automated transport mechanism 302 includes a transport support unit 3021 and a transport moving unit 3022. The transport support unit 3021 is used to lift and support the finished product rack stack. The transport moving unit 3022 is used to move the automated transport mechanism 302. In this embodiment, the transport support unit 3021 is mounted on the transport moving unit 3022. The transport support unit 3021 includes a support bracket 30211 and a lifting frame 30212. The support bracket 30211 is used to support the finished product rack stack. The lifting frame 30212 is used for vertical lifting. The support bracket 30211 is mounted on the lifting frame 30212.

[0116] The loading control mechanism controls the automatic traying mechanism to place the finished automotive radiator pressure caps assembled by the parts assembly mechanism into the finished product rack 3011 in sequence, controls the automatic stacking mechanism 301 to stack the finished product racks 3011 filled with finished automotive radiator pressure caps in sequence, and controls the automatic transport mechanism 302 to move all the finished product racks 3011 stacked to the specified number of layers to the preset storage position.

[0117] The conveyor 31 is used to transfer the semi-finished automotive water tank pressure cap between various workstations.

[0118] The conveying equipment includes a transfer mechanism and a transfer control mechanism.

[0119] The transfer mechanism is used to support semi-finished and finished automotive radiator pressure caps. The transfer mechanism includes a circular assembly line, a transfer drive unit, multiple support fixtures, multiple sensor placement units, and multiple station positioning blocks.

[0120] The flow drive unit drives the circular production line. Multiple support fixtures are installed on the circular production line to support semi-finished and finished automotive radiator pressure caps. Multiple placement sensors are installed on the circular production line to detect the presence of semi-finished or finished automotive radiator pressure caps on the support fixtures. Multiple station positioning blocks are installed on the circular production line, each corresponding to a specific station.

[0121] The transfer control mechanism is used to control the transfer of semi-finished and finished automotive radiator pressure caps.

[0122] After the assembly equipment at the corresponding workstation completes the assembly of the corresponding automotive radiator pressure cap semi-finished product, the flow control mechanism controls the workstation positioning block to retract and controls the flow drive unit to drive the circular production line, causing the support fixture to leave the workstation. After the support fixture leaves the workstation, the flow control mechanism controls the workstation positioning block to extend, preventing the next support fixture flowing to that workstation from continuing to move, thus stopping the support fixture at that workstation.

[0123] In this embodiment, the assembly equipment corresponding to the workstation includes rubber pad assembly equipment 21, balance valve assembly equipment 22, spring assembly equipment 23, top cover assembly equipment 24, top cover pressing equipment 25, sealing ring assembly equipment 26, airtightness testing equipment 27, threaded cover screen printing equipment 28, threaded cover assembly equipment 29, and finished product stacking equipment.

[0128] The parts storage bin is used to store automotive radiator pressure cap parts conveyed by the automatic feeding mechanism and to supply automotive radiator pressure cap parts to the parts vibratory feeder.

[0129] The material level sensor is installed inside the parts storage bin to detect the material level data of the automotive water tank pressure cap parts in the parts storage bin.

[0130] The vibratory feeder is used to output oriented automotive radiator pressure cap parts.

[0131] The feeding control mechanism stores preset material level thresholds and receives material level data sent by the material level sensor in real time.

[0132] When the material level data is lower than the preset material level threshold, the feeding control mechanism controls the automatic feeding mechanism to feed the parts feeding mechanism until the material level data is not lower than the preset material level threshold.

[0133] Storage equipment is used to store automotive radiator pressure cap parts.

[0134] The automatic feeding equipment is used to supply the corresponding automotive water tank pressure cap parts to the parts feeding mechanism of the rubber pad assembly equipment 21, balance valve assembly equipment 22, spring assembly equipment 23, top cover assembly equipment 24, sealing ring assembly equipment 26, airtightness testing equipment 27 and threaded cover screen printing equipment 28, respectively.

[0137] like Figure 11 As shown, the automatic feeding mechanism 321 includes a feeding moving unit 3211, a support frame 3212, and a storage unit 3213. The support frame 3212 is mounted on the feeding moving unit 3211, and the storage unit 3213 is mounted on the support frame 3212.

[0138] The storage unit 3213 includes a storage hopper 32131, a discharge gate 32132, and a stop bar 32133.

[0139] The storage hopper 32131 is used to store automotive radiator pressure cap parts obtained from the storage equipment. A discharge gate 32132 is located at the lower opening of the storage hopper 32131. A stop lever 32133 is mechanically connected to the discharge gate 32132 and is used to control the opening and closing of the discharge gate 32132.

[0140] When the feeding control mechanism controls the feeding moving unit 3211 to retrieve material from the storage equipment along a preset path, the stop lever 32133 is in the first position, causing the discharge gate 32132 to close, and the automotive radiator pressure cap parts are stored in the storage hopper 32131. The feeding control mechanism controls the feeding moving unit 3211 to move along the preset path until the parts storage box is in front of the storage hopper 32131. The control mechanism then controls the feeding moving unit 3211 to continue moving forward until the stop lever 32133 contacts the parts storage box, causing the stop lever 32133 to be pressed and moved to the second position, thereby opening the discharge gate 32132, and the automotive radiator pressure cap parts fall from the lower opening of the storage hopper 32131 into the parts storage box.

[0141] The central control equipment is used to control the rubber gasket assembly equipment 21, balance valve assembly equipment 22, spring assembly equipment 23, top cover assembly equipment 24, top cover pressing equipment 25, sealing ring assembly equipment 26, airtightness testing equipment 27, threaded cap screen printing equipment 28, threaded cap assembly equipment 29, finished product stacking equipment 30, conveying equipment 31, material storage equipment, and automatic feeding equipment, so as to realize the assembly and storage of automotive water tank pressure caps.

[0146] In step V2, the main control equipment controls the balance valve assembly equipment 22 to assemble the balance valve 13 on the semi-finished automotive water tank pressure cap, and controls the conveying equipment 31 to transfer the semi-finished automotive water tank pressure cap to the next station.

[0147] In step V3, the main control equipment controls the spring assembly equipment 23 to assemble the spring 14 into the semi-finished automotive radiator pressure cap, and controls the conveying equipment 31 to transfer the semi-finished automotive radiator pressure cap to the next station.

[0150] In step V6, the main control equipment controls the sealing ring assembly equipment 29 to assemble the sealing rings on the semi-finished automotive radiator pressure cap, and controls the conveying equipment 31 to transfer the semi-finished automotive radiator pressure cap to the next station.

[0151] In step V7, the main control equipment controls the air tightness testing equipment 27 to determine whether the air tightness of the semi-finished car radiator pressure cap is qualified. If it is, the control equipment 31 is controlled to transfer the semi-finished car radiator pressure cap to the next station and step V8 is executed. If not, the semi-finished car radiator pressure cap is a defective product.

[0152] In step V8, the main control equipment controls the threaded cap screen printing equipment 28 to screen print on the threaded cap 18.

[0153] In step V9, the main control equipment controls the threaded cap assembly equipment 29 to assemble the silk-screened threaded cap 18 onto the semi-finished automotive radiator pressure cap, thus obtaining the finished automotive radiator pressure cap.

[0154] In step V10, the central control equipment controls the finished product stacking equipment 30 to stack multiple finished automotive water tank pressure caps and place them in the preset storage location.

[0155] Figure 13 This is a schematic flowchart of the rubber pad assembly process in an embodiment of the present invention.

[0156] like Figure 13 As shown, the rubber pad assembly control unit controls the three-axis moving unit 2112 and the adsorption clamping unit 2113 to perform the assembly process of the rubber pad 12, which includes the following steps:

[0158] In step T2, the housing sensor 21134 detects whether housing 11 exists. If it does, the housing gripper 21133 grips housing 11 and proceeds to step T3. If not, proceeds to step T1.

[0159] In step T3, the rubber pad assembly control unit controls the three-axis moving unit 2112 to move, so that the rubber pad adsorption component 21132 contacts the rubber pad 12, and controls the vacuum generator to continuously generate suction, so that the rubber pad adsorption component 21132 adsorbs the rubber pad 12.

[0160] Step T4: The vacuum generator checks whether the rubber pad 12 is adsorbed. If yes, proceed to step T5; otherwise, proceed to step T3.

[0161] In step T5, the rubber pad assembly control unit controls the movement of the three-axis moving unit 2112 and controls the opening of the housing gripper 21133, so that the housing 11 is placed in the first preset position. In this embodiment, the first preset position is a support fixture.

[0162] Step T5 includes the following sub-steps:

[0164] Step T5-2: Place a sensor to detect whether there is a shell 11, i.e., whether there is a semi-finished car water tank pressure cap. If yes, proceed to step T5-3; otherwise, proceed to step T5-1.

[0165] In step T5-3, the rubber pad assembly control unit controls the housing gripper 21133 to open, so that the housing 11 is placed on the support fixture.

[0166] In step T6, the rubber pad assembly control unit controls the three-axis moving unit 2112 to move the rubber pad 12 to the second preset position of the housing 11. In this embodiment, the second preset position is the location inside the housing 11 where the rubber pad 12 needs to be placed.

[0167] In step T7, the rubber pad assembly control unit controls the rubber pad adsorption assembly 21132 to stop generating suction, so that the rubber pad 12 is placed in the second preset position.

[0177] In step U8, the sealing ring assembly control mechanism controls the gripping mechanism to grab the semi-finished automotive water tank pressure cap from the small O-ring assembly mechanism and place it on the conveying equipment 31.

[0178] In this embodiment, the large O-ring 16 is assembled first, followed by the small O-ring 17. In other embodiments, the above process can be adjusted according to actual needs, so that the small O-ring 17 is assembled first, followed by the large O-ring 16.

[0179] Figure 15 This is a schematic diagram of the assembly process of the large O-ring in an embodiment of the present invention.

[0180] like Figure 15 As shown, the process of assembling the large O-ring on the semi-finished automotive radiator pressure cap includes the following steps:

[0181] Step S1: The sealing ring assembly control mechanism controls the large O-ring feeding unit to output large O-ring 16.

[0182] In step S2, the sealing ring assembly control mechanism controls the large O-ring detection unit 261 to determine whether there is a defect in the large O-ring 16. If so, the sealing ring assembly control mechanism controls the large O-ring transport unit 264 to transport the large O-ring 16 to the large O-ring waste box 265 and executes step S1. If not, step S3 is executed.

[0183] In step S3, the sealing ring assembly control mechanism controls the large O-ring transport unit 264 to transport the large O-ring 16 to the large O-ring oiling unit 262.

[0184] In step S4, the sealing ring assembly control mechanism controls the large O-ring oiling unit 262 to apply oil to the large O-ring 16.

[0185] Step S4 includes the following sub-steps:

[0186] Step S4-1: The sealing ring assembly control mechanism controls the large O-ring transport unit 264 to leave the large O-ring oiling unit 262.

[0187] In step S4-2, the sealing ring assembly control mechanism controls the movement of the movable bracket 2625 so that the oil-proof cover 2626 covers the opening of the placement groove 2622.

[0188] Step S4-3: The sealing ring assembly control mechanism controls the injector 2624 to inject oil.

[0189] In step S4-4, the sealing ring assembly control mechanism controls the movement of the movable bracket 2625 so that the oil cover 2626 no longer covers the opening of the placement groove 2622.

[0190] In step S5, the sealing ring assembly control mechanism controls the large O-ring transport unit 264 to transport the large O-ring 16 to the large O-ring assembly unit 263.

[0193] In step S5-2, the sealing ring assembly control mechanism controls the placement detection component 2634 to detect whether the large O-ring 16 is on the fixed component 2632. If yes, then step S6 is executed; otherwise, the sealing ring assembly control mechanism controls the large O-ring transport unit 264 to reposition the large O-ring 16 and executes step S5-2.

[0194] In step S6, the sealing ring assembly control mechanism controls the gripping mechanism to transport the semi-finished automotive water tank pressure cap from the designated position to the large O-ring assembly unit 263.

[0195] Step S6 includes the following sub-steps:

[0196] In step S6-1, the sealing ring assembly control mechanism controls the first drive component to expand the fixed claw 26321 outward until the large O-ring 16 is expanded to a specified extent, and causes the fixed claw 26321 to rise and fall vertically until it reaches the preset assembly position.

[0197] In step S6-2, the sealing ring assembly control mechanism controls the gripping mechanism to grip the semi-finished automotive water tank pressure cap from the designated position and place it on the fixed hook 26321.

[0198] In step S7, the sealing ring assembly control mechanism controls the large O-ring assembly unit 263 to fit the large O-ring 16 onto the semi-finished automotive water tank pressure cap.

[0199] Step S7 includes the following sub-steps:

[0200] In step S7-1, the sealing ring assembly control mechanism controls the second drive component to move the push post 26331, so that the upper surface of the push post 26331 contacts the large O-ring 16 without touching the semi-finished automotive radiator pressure cap. In step S7-1 of this embodiment, the upper surface of the push post 26331 contacts the lower surface of the large O-ring 16.

[0201] In step S7-2, the sealing ring assembly control mechanism controls the second drive component to raise the push column 26331, causing the push column 26331 to push the large O-ring 16 away from the fixed hook 26321 and onto the semi-finished automotive water tank pressure cap.

[0202] In step S8, the sealing ring assembly control mechanism controls the gripping mechanism to transport the semi-finished automotive radiator pressure cap from the large O-ring assembly unit 263 to the designated position. In this embodiment, the designated position in steps S6-2 and S8 is the support fixture located at the large O-ring assembly station.

[0203] In this embodiment, the assembly process of the small O-ring 17 is the same as the assembly process of the large O-ring 16 described above, so it will not be repeated.

[0204] The following description, in conjunction with the accompanying drawings, illustrates the process of supplying automotive radiator pressure cap parts and transporting finished automotive radiator pressure caps using an automatic feeding device and a finished product stacking device 30 via an automotive radiator pressure cap assembly system 200.

[0205] Figure 16 This is a schematic diagram illustrating the process of automatic feeding of automotive radiator pressure cap parts and automatic loading of finished automotive radiator pressure caps in an embodiment of the present invention.

[0206] like Figure 16 As shown, the automatic feeding of automotive radiator pressure cap parts and the automatic loading of finished automotive radiator pressure caps include the following steps:

[0207] Step C1: The feeding control mechanism controls the automatic feeding mechanism storing the automotive water tank pressure cap parts to feed the parts to the parts feeding mechanism.

[0208] Step C2: The assembly control mechanism controls the parts feeding mechanism to output the oriented automotive water tank pressure cap parts.

[0209] Step C3: The assembly control mechanism controls the parts assembly mechanism to assemble the automotive radiator pressure cap parts output by the parts feeding mechanism to obtain the finished automotive radiator pressure cap.

[0210] In step C4, the loading control mechanism controls the automatic palletizing mechanism to place the finished car water tank pressure cap into the finished product rack 3011 of the automatic stacking mechanism 301.

[0211] In step C5, the loading control mechanism controls the automatic stacking mechanism 301 to stack the finished product racks 3011 filled with finished automotive water tank pressure caps in sequence.

[0212] In step C6, the loading control mechanism controls the automatic transport mechanism 302 to move all the finished product racks 3011 stacked to the specified number of layers to the preset storage position.

[0213] Figure 17 This is a schematic diagram of the process of stacking finished product racks in an embodiment of the present invention.

[0214] like Figure 17As shown, the process of placing the finished automotive radiator pressure cap on the finished product rack 3011 and stacking the finished product rack 3011 includes the following steps:

[0215] In step A1, the loading control mechanism controls the gripper assembly 30122 to descend and grab the empty finished product rack 3011 at the top of the finished product rack stack.

[0216] In step A2, the loading control mechanism controls the gripper assembly 30122 to rise and move laterally to directly above the stacking unit 3013.

[0217] In step A3, the loading control mechanism controls the gripper assembly 30122 to descend and places the empty finished product rack 3011 on the stacking unit 3013.

[0218] Step A4: The loading control mechanism controls the gripper assembly 3013 to move to the initial position.

[0219] In step A5, the loading control mechanism controls the automatic tray loading mechanism to grab the finished automotive radiator pressure cap and place it in the empty finished product rack 3011 until the finished product rack 3011 is full of finished automotive radiator pressure caps.

[0220] In step A6, the loading control mechanism controls the stacking unit 3013 to move laterally until the full finished product rack 3011 moves directly under the finished product rack stack.

[0221] In step A7, the loading control mechanism raises the stacking unit 3013 until the full finished product rack 3011 overlaps with the finished product rack stack. In this embodiment, when the full finished product rack 3011 overlaps with the finished product rack stack, the full finished product rack 3011 supports the finished product rack stack.

[0222] In step A8, the loading control mechanism retracts the handle assembly 30122 and continues to raise the stacking unit 3013 until the full finished product rack reaches the specified height. In this embodiment, the specified height is reached when the bottom surface of the full finished product rack 3011 is higher than the upper surface of the rack handle 30131 of the handle assembly 30122.

[0223] In step A9, the loading control mechanism controls the extension of the handle assembly 30122 and controls the lowering of the stacking unit 3013 until the handle assembly 30122 supports the finished product rack stack.

[0224] In step A10, the shipping control mechanism controls the stacking unit 3013 to move to the initial position.

[0225] Figure 18 This is a schematic diagram of the process of moving and storing the finished automotive water tank pressure cap in an embodiment of the present invention.

[0226] like Figure 18As shown, the process by which the loading control mechanism controls the automated transport mechanism 302 to move the finished product rack to a preset storage location includes the following steps:

[0227] Step B1: The loading control mechanism controls the transport moving unit 3022 to move along the first preset route to directly below the finished product rack pile filled with automotive water tank pressure caps.

[0228] In step B2, the loading control mechanism controls the transport support unit 3021 to rise and support the finished product rack stack.

[0229] Step B3: The loading control mechanism controls the left and right hand extension cylinders to retract the left hand 301211 and the right hand 30122.

[0230] In step B4, the loading control mechanism controls the transport support unit 3021 to descend to the specified height, so that the finished product rack is completely placed on the automatic transport mechanism 302.

[0231] In step B5, the loading control mechanism controls the transport moving unit 3022 to move along the second preset route to the preset storage location.

[0232] The role and effect of the embodiments

[0233] According to the automotive radiator pressure cap assembly system involved in this embodiment, the control of the conveying equipment, rubber gasket assembly equipment, balance valve assembly equipment, spring assembly equipment, top cover assembly equipment, top cover pressing equipment, sealing ring assembly equipment, airtightness testing equipment, threaded cap screen printing equipment, and threaded cap assembly equipment through the central control equipment enables the sequential assembly of each automotive radiator pressure cap component and the performance of airtightness testing, thereby obtaining the finished automotive radiator pressure cap. This achieves a highly automated automotive radiator pressure cap assembly, improving production efficiency and reducing the defect rate caused by human assembly errors.

[0234] Furthermore, in this embodiment, the automatic stacking mechanism supports the finished product racks via a handle assembly and places the empty finished product rack at the top of the stack onto the rack handle of the stacking unit via a gripper assembly. Then, an automatic traying mechanism fills the empty finished product racks with finished automotive radiator pressure caps. Subsequently, through the horizontal movement and lifting of the stacking unit, and the extension and retraction of the handle assembly, the finished product racks filled with finished automotive radiator pressure caps are stacked at the bottom of the finished product rack stack. Therefore, the automatic stacking mechanism can achieve stable and rapid stacking of multiple finished product racks.

[0235] Furthermore, in this embodiment, the automated transport mechanism moves back and forth between the automated stacking mechanism and the preset storage location via a transport moving unit, and carries the finished product rack stack from the automated stacking mechanism via a transport supporting unit. Therefore, the automated transport mechanism can autonomously and accurately stack finished automotive radiator pressure caps to the preset storage location.

[0236] Furthermore, the automatic feeding mechanism in this embodiment can move the feeding moving unit to bring the stop bar into contact with the parts storage bin, causing the stop bar to move and opening the discharge gate mechanically connected to the stop bar. This allows the automotive radiator pressure cap parts in the storage hopper to fall into the parts storage bin. After the feeding moving unit moves away from the parts storage bin, the stop bar automatically resets, closing the discharge gate. This facilitates the storage hopper retrieving and storing the automotive radiator pressure cap parts from the storage equipment. Therefore, the automatic feeding mechanism can efficiently and stably transport automotive radiator pressure cap parts from the storage equipment to the corresponding parts storage bin.

[0237] Furthermore, the sealing ring assembly equipment in this embodiment uses a sealing ring detection unit to detect defects in the sealing ring, a sealing ring oiling unit to apply oil, a sealing ring assembly unit to assemble the sealing ring, and a sealing ring transport unit and a gripping mechanism to transport the sealing ring and the semi-finished automotive radiator pressure cap. The sealing ring assembly unit adjusts the sealing ring to a suitable size and positions it appropriately with the semi-finished automotive radiator pressure cap by contracting, expanding, and lowering the fixed hooks. Then, the movement of the pusher causes the sealing ring to disengage from the fixed hooks, and under its own retraction, it is fitted into the designated position, thus completing the sealing ring fitting. Therefore, the sealing ring assembly equipment can achieve efficient and accurate sealing ring fitting.

[0238] Furthermore, the adsorption and gripping mechanism of the rubber pad assembly equipment in this embodiment uses an adsorption head with multiple suction holes to adsorb the rubber pad. A telescopic floating connector makes the force when the adsorption head descends and contacts the rubber pad gentler, avoiding damage to both the adsorption head and the rubber pad, and providing greater pressure for the adsorption head to contact the rubber pad, allowing for a tight fit and better adsorption. In addition, the grooves in the jaws accommodate the upper edge of the housing, ensuring a stable grip on the housing. Therefore, the adsorption and gripping mechanism effectively adsorbs the rubber pad and holds the housing, effectively preventing the housing and rubber pad from detaching during movement.

[0239] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
