[0033] Refer to FIG. 1 , which shows a schematic structural diagram of an automatic assembly device in an embodiment of the present application. The automatic assembly device provided in an embodiment of the present application is suitable for assembling an ABS valve body.

[0034] For ease of understanding, before describing the automatic assembly device of the present application, the structure of the ABS valve body is explained here, but this does not limit the execution steps or execution methods of the various mechanisms of the automatic assembly device in the present application.

[0035] Referring to FIG8 , in some embodiments, the ABS valve body 10 includes a valve body, the valve body is provided with a valve nozzle pressure port 11, a steel ball pressure port 12, and a gasket placement portion 13, and the valve nozzle pressure port 11, the steel ball pressure port 12, and the gasket placement portion 13 are respectively opened at different positions of the valve body. It can be understood that the gasket placement portion 13, the steel ball pressure port 12, and the valve nozzle pressure port 11 are holes or slots provided at different positions of the valve body. The above-mentioned "ABS valve body" is referred to as a "workpiece" hereinafter.

[0036] As shown in FIG. 1 and FIG. 2 , in one embodiment, the automatic assembly device provided by the present application includes a feeding mechanism 100, a gasket placement mechanism, a riveting mechanism 500, a pressing mechanism, a feeding mechanism 800 and a transfer component 900. The feeding mechanism 100 is used to feed the workpiece 10 and transport it to the transfer component 900. The transfer component 900 is used to clamp the workpiece 10 and transfer the workpiece 10 to the gasket placement mechanism, the riveting mechanism 500, the pressing mechanism and the feeding mechanism 800 in sequence. The gasket placement mechanism includes a first placement mechanism 200, a second placement mechanism 300 and a third placement mechanism 400, and is used to place a silencer pad, a flat pad and a rubber pad on the workpiece 10 in sequence. The riveting mechanism 500 is used to rivet the silencer pad, the flat pad and the rubber pad to the gasket placement portion 13 of the workpiece 10. The pressing mechanism includes a first pressing mechanism 600 and a second pressing mechanism 700. The workpiece 10 has a valve nozzle pressure port 11 and a steel ball pressure port 12 arranged at different positions. The first pressing mechanism 600 and the second pressing mechanism 700 are respectively provided with a first rotating part 660 and a second rotating part 760. When the transfer component 900 transfers the workpiece 10 to the first pressing mechanism 600, the first rotating part 660 is connected to the transfer component 900, and drives the workpiece 10 to flip by a first preset angle so that the first pressing mechanism 600 presses the steel ball toward the steel ball pressure port 12; when the transfer component 900 transfers the workpiece 10 to the second pressing mechanism 700, the second rotating part 760 is connected to the transfer component 900, and drives the workpiece 10 to flip by a second preset angle so that the second pressing mechanism 700 presses the valve nozzle 20 toward the valve nozzle pressure port 11. When the transfer component 900 transfers the workpiece 10 to the unloading mechanism 800, the unloading mechanism 800 is used to clamp and unload the workpiece 10.

[0037] It should be noted that, in conjunction with FIG. 2 , the first rotating portion 660 is arranged to be opposite to the riveting mechanism 500, so that the workpiece 10 can be directly flipped at an angle after the riveting operation is completed, and then transferred to the first pressing mechanism 600 at a suitable angle for the steel ball pressing operation. It can be understood that the setting position of the first rotating portion 660 can be adjusted according to actual needs, that is, the first rotating portion 660 can also be arranged to be opposite to the first pressing mechanism 600, so that after the workpiece 10 is transferred to the workstation where the first pressing mechanism 600 is located, the first rotating portion 660 first flips the workpiece 10 at a first preset angle, and then performs the steel ball pressing operation.

[0038] When the above-mentioned automatic assembly device is in use, the workpiece 10 to be assembled is first loaded through the loading mechanism 100, and then the workpiece 10 is transferred to the first placement mechanism 200, the second placement mechanism 300, the third placement mechanism 400, the riveting mechanism 500, the first pressing mechanism 600, the second pressing mechanism 700 and the unloading mechanism 800 in sequence through the transfer component 900, and the silencer pads, flat pads, rubber pads, riveting, steel ball pressing, valve nozzle 20 pressing and unloading processes are performed in sequence; on the one hand, the transfer component 900 transfers the workpiece 10, which helps to improve the assembly efficiency; on the other hand, when the workpiece 10 is subjected to the steel ball pressing and valve nozzle 20 pressing processes, the workpiece 10 needs to be flipped to a suitable angle to adapt to the pressing angles of the first pressing mechanism 600 and the second pressing mechanism 700, so as to improve the pressing accuracy. The first pressing mechanism 600 and the second pressing mechanism 700 are respectively provided with a first rotating part 660 and a second rotating part 760, so that the workpiece 10 can be flipped at a preset angle to adjust the angles of the steel ball pressure port 12 and the valve nozzle pressure port 11 of the workpiece 10, and then adapt to the pressing angle of the pressing mechanism to realize the automatic assembly of the steel ball pressing and the valve nozzle 20 pressing. Therefore, the automatic assembly device can realize full automation of assembly, avoid the uncertainties caused by manual assembly, improve product consistency and product quality, and effectively improve assembly efficiency.

[0039] Optionally, in combination with what is shown in FIG2 , the automatic assembly device may, but is not limited to, further include a material vibration mechanism 1000, which is used to transport materials such as silencer pads, flat pads, rubber pads, steel balls, rivets, and valve nozzles 20 in a directionally directed manner to the first placement mechanism 200, the second placement mechanism 300, the third placement mechanism 400, the riveting mechanism 500, the first pressing mechanism 600, and the second pressing mechanism 700.

[0040] Optionally, the transfer component 900 may be implemented as, but not limited to, a directional transfer mechanism such as a conveyor belt or a conveyor disc.

[0041] Preferably, in combination with Figure 3, in some embodiments, the transfer component 900 can be implemented, but is not limited to, as a turntable 920 and a clamp 910, and the loading mechanism 100, the first placement mechanism 200, the second placement mechanism 300, the third placement mechanism 400, the riveting mechanism 500, the first pressing mechanism 600, the second pressing mechanism 700 and the unloading mechanism 800 are arranged around the rotation center of the turntable 920 at intervals, and the turntable 920 is provided with a clamp 910 that is aligned with the loading mechanism 100, the first placement mechanism 200, the second placement mechanism 300, the third placement mechanism 400, the riveting mechanism 500, the first pressing mechanism 600, the second pressing mechanism 700 and the unloading mechanism 800, and the clamp 910 is used to clamp the workpiece 10.

[0042] It should be noted that, in Fig. 3, only a schematic diagram of the structure of one of the clamps 910 is shown, and the structures of the other clamps 910 are not repeated in Fig. 3. The turntable 920 can rotate around the rotation center so that each clamp 910 can be transferred in sequence in the feeding mechanism 100, the first placement mechanism 200, the second placement mechanism 300, the third placement mechanism 400, the riveting mechanism 500, the first pressing mechanism 600, the second pressing mechanism 700 and the unloading mechanism 800.

[0043] Specifically, by arranging the mechanisms at intervals around the rotation center of the turntable 920, a circular layout of the mechanisms is achieved, which helps save space and improves the structural compactness of the automatic assembly device. The workpieces 10 can be transferred and assembled in sequence by rotating the turntable 920, and the structure is simple and reliable, and the control is simple. In addition, by aligning the fixture 910 with each mechanism one by one, the fixture 910 can be cyclically aligned with each mechanism under the drive of the turntable 920, so that uninterrupted production of the workpieces 10 can be achieved, which helps improve assembly efficiency.

[0044] For example, when the workpiece 10 on the fixture 910 aligned with the feeding mechanism 100 is transferred to the next process, the feeding mechanism 100 will be aligned with the next fixture 910, and the fixture 910 aligned with the feeding mechanism 100 is in an idle state, so that the next workpiece 10 to be assembled can be placed in the fixture 910 aligned with the feeding mechanism 100, and then when the turntable 920 rotates one station angle, the assembly of a workpiece 10 can be completed and unloaded, and a workpiece 10 can be loaded, which effectively improves the assembly efficiency. It is understandable that the turntable 920 needs to wait until all processes have completed the assembly operation before rotating, and only rotates one station angle to realize the sequential assembly of the workpieces 10.

[0045] Optionally, in combination with FIG. 2 and FIG. 3 , the feeding mechanism 100 may be provided with, but not limited to, a third rotating portion 110, which is used to connect with the fixture 910 and drive the fixture 910 to flip to a third preset angle to reset the fixture 910 to an initial state for clamping the workpiece 10. Specifically, a corresponding third rotating portion 110 is provided in the feeding mechanism 100, so that the fixture 910 aligned with the feeding mechanism 100 can be flipped and reset, so as to facilitate the loading of the next workpiece 10 to be assembled, thereby improving the full automation of automatic assembly.

[0046] Preferably, continuing to refer to Figure 3, the first rotating part 660, the second rotating part 760 and the third rotating part 110 can, but are not limited to, each include a driver 1110, a first rotating member 1120 and a second rotating member 1130, the first rotating member 1120 is connected to the driver 1110, the driver 1110 is used to drive the first rotating member 1120 to approach or move away from the second rotating member 1130 along a first direction, and enable the first rotating member 1120 to engage with the second rotating member 1130, the second rotating member 1130 is connected to the clamp 910, the driver 1110 is used to drive the first rotating member 1120 to rotate around the first direction, so as to drive the clamp 910 to flip when the first rotating member 1120 and the second rotating member 1130 are engaged, thereby realizing the angular flipping of the workpiece 10.

[0047] More preferably, the driver 1110 has an output shaft, and the first direction refers to the direction along the axis of the output shaft; and around the first direction refers to the direction around the axis of the output shaft.

[0048] Specifically, in this embodiment, the first rotating member 1120 may be, but is not limited to, implemented as having a joint, and the second rotating member 1130 may be, but is not limited to, implemented as having a slot. When the driver 1110 drives the first rotating member 1120 to move in the first direction close to the second rotating member 1130, the joint of the first rotating member 1120 can be engaged with the slot of the second rotating member 1130, so that when the first rotating member 1120 is driven to rotate by the driver 1110, the second rotating member 1130 can be driven to rotate, thereby realizing the angle flipping of the fixture 910 and the workpiece 10. After the workpiece 10 completes the flipping action, the driver 1110 can drive the first rotating member 1120 to separate in the direction away from the second rotating member 1130, so that the fixture 910 can be transferred and the next assembly process can be carried out.

[0049] Preferably, referring to Fig. 3, the first rotating part 660, the second rotating part 760 and the third rotating part 110 may, but are not limited to, each further include a positioner 1140, and the positioner 1140 is used to position the flip angle of the workpiece 10, which helps to improve the accuracy of the flip angle of the workpiece 10. Optionally, the positioner 1140 may, but is not limited to, be implemented as a positioning sensor or a positioning lock.

[0050] More preferably, the positioner 1140 may be implemented, but not limited to, to include a positioning body 1141 and a ball 1142, wherein the ball 1142 is embedded in the positioning body 1141. The circumferential surface of the second rotating member 1130 around the first direction is provided with at least two evenly distributed grooves 1130a, and the ball 1142 is used to abut against the circumferential surface of the second rotating member 1130. When the second rotating member 1130 rotates around the first direction, the ball 1142 can be sequentially engaged with any groove 1130a, thereby realizing the rotation positioning of the second rotating member 1130.

[0051] It should be noted that, generally, during the assembly process of the ABS valve body, the workpiece 10 needs to be turned over 90° during the steel ball pressing process and the valve mouth 20 pressing process to adapt to the pressing angles of the first pressing mechanism 600 and the second pressing mechanism 700. Therefore, preferably, the grooves 1130a are arranged at intervals of 45° around the rotation center of the second rotating member 1130, so that the positioning accuracy of the positioner 1140 can be improved. In addition, after the steel ball pressing process and the valve mouth 20 pressing process, the workpiece 10 is turned over twice, that is, the workpiece 10 is turned over 180° in total, so the third rotating part 110 is also provided in the feeding mechanism 100, so that the clamp 910 can be turned over and reset before feeding, which helps to improve the simplicity of feeding.

[0052] Optionally, in combination with what is shown in FIG4 , the first pressing mechanism 600 may include, but is not limited to, a feed port 610, a conveying module 620 and a first pressing rod 630, the feed port 610 is connected to the conveying module 620, the feed port 610 is used for feeding steel balls, the conveying module 620 is used for conveying the steel balls entering the feed port 610 and aligning them with the steel ball pressing port 12 of the workpiece 10, and the first pressing rod 630 is used for pressing the steel balls into the workpiece 10.

[0053] It can be understood that the conveying module 620 has an opening. When the fixture 910 clamps the workpiece 10 and is transferred to the workstation where the first pressing mechanism 600 is located, the first pressing rod 630, the opening of the conveying module 620 and the steel ball pressing port 12 of the workpiece 10 are in a straight line, thereby improving the accuracy of the first pressing rod 630 pressing the steel ball.

[0054] Preferably, the first pressing mechanism 600 also includes a first displacement sensor 640 and a first pressure sensor 650. The first displacement sensor 640 is used to monitor the downward displacement of the first pressing rod 630, and the first pressure sensor 650 is used to monitor the axial pressure borne by the first pressing rod 630. In this way, the pressure and displacement of the steel ball pressed in can be monitored in real time, and the quality of the steel ball pressed in can be judged by the pressure and displacement.

[0055] Optionally, in combination with Figures 6 to 8, the second pressing mechanism 700 may include but is not limited to a pressing cylinder 710, a pressing gun 720 and a second pressing rod 730, the pressing gun 720 having a hollow cavity 720a and a muzzle 721, the second pressing rod 730 being telescopically penetrated in the hollow cavity 720a, the muzzle 721 being adapted to the valve nozzle pressure port 11 of the workpiece 10 and being used to press the valve nozzle pressure port 11, the hollow cavity 720a being used to accommodate the valve nozzle 20, and the second pressing rod 730 being used to press the valve nozzle 20 into the workpiece 10 along the axial direction of the hollow cavity 720a.

[0056] It should be noted that during the pressing process of the valve nozzle 20, the tolerance of the assembly position of the valve nozzle 20 and the workpiece 10 is very small, and the pressing depth of the valve nozzle 20 is required to be flush with the pressing entrance of the workpiece 10. The tolerance allowed for flush pressing is also small, so it is difficult to assemble it through mechanized automatic assembly. In this embodiment, the present application designs the muzzle 721 of the pressure gun 720 to be compatible with the valve nozzle pressure port 11 of the workpiece 10. It should be noted that the adaptation at least includes matching of outer contour and size, and the pressure gun 720 is hollow for accommodating the valve nozzle 20. In this way, when the valve nozzle 20 is pressed down for assembly, the pressure gun 720 can be placed on the valve nozzle pressure port 11 of the workpiece 10 first, so that the muzzle 721 of the pressure gun 720 matches the outer contour and size of the valve nozzle pressure port 11, and then the pressure gun 720, the second pressure rod 730 and the valve nozzle pressure port 11 of the workpiece 10 are on the same axis, and then the valve nozzle 20 is pushed to and pressed into the valve nozzle pressure port 11 of the workpiece 10 by the second pressure rod 730. In this way, it can be ensured that during the pressing process, the second pressure rod 730 will not deviate in a certain direction to cause damage to the valve nozzle 20 and the workpiece 10, thereby reducing the pressing error and improving the pressing accuracy.

[0057] Preferably, referring to FIG. 6 again, the second pressing rod 730 is provided with a limiting portion 731, the limiting portion 731 is exposed from the pressing gun 720, and the exposed portion of the limiting portion 731 serves as the pressable depth of the second pressing rod 730, and the pressable depth is adapted to the pressable depth of the valve nozzle 20 of the workpiece 10 to be assembled, so that the pressable depth of the valve nozzle 20 can be controlled by controlling the exposed length of the limiting portion 731 of the second pressing rod 730. Through the above arrangement, the second pressing rod 730 can be adjusted to a matching pressable depth, and then when the second pressing rod 730 is pressed to the bottom by the pressing cylinder 710, the valve nozzle 20 can be just flush with the valve nozzle pressure port 11, and it is guaranteed to be within the tolerance range required by the process, effectively improving the assembly consistency and assembly quality.

[0058] More preferably, referring to FIG. 6 , in order to ensure the reliability of the pressing process of the valve nozzle 20, in some embodiments, the second pressing mechanism 700 further includes a second displacement sensor 740 and a second pressure sensor 750. The second displacement sensor 740 is used to monitor the pressing displacement of the second pressing rod 730, and the second pressure sensor 750 is used to monitor the axial pressure borne by the second pressing rod 730. In this way, it is possible to monitor in real time whether the pressing depth of the valve nozzle 20 meets the requirements and whether the pressing pressure is within the normal range, so as to prevent damage to the valve nozzle 20 during the pressing process and reduce the outflow of defective products, thereby effectively improving the quality of the pressing of the valve nozzle 20.

[0059] Optionally, the automatic assembly device may, but is not limited to, also include an in-position sensor (not shown), which is used to monitor whether the clamp 910 aligned with the first placement mechanism 200, the second placement mechanism 300, the third placement mechanism 400, the riveting mechanism 500, the first pressing mechanism 600 and the second pressing mechanism 700 has a workpiece 10 in place, so as to issue an automatic assembly signal.

[0060] Preferably, the automatic assembly device may, but is not limited to, also include a manipulator assembly (not shown) and a controller 1200. When the controller 1200 receives the above-mentioned automatic assembly signal, the manipulator assembly can adaptively grab the corresponding material and transfer it to the corresponding assembly position (station) for the first placement mechanism 200, the second placement mechanism 300, the third placement mechanism 400, the riveting mechanism 500, the first pressing mechanism 600 and the second pressing mechanism 700 to automatically complete the assembly.

[0061] Preferably, the controller 1200 is connected to the signals of each mechanism and can control the assembly operation of each mechanism individually or jointly, which helps to improve the control flexibility of the automatic assembly device.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
