Description

Technical Field

[0001] The present application relates to the field of automobile safety technology, and in particular to an automatic assembly device. Background Art

[0002] The ABS (Anti-lock Braking System) valve body is a core component of the anti-lock braking system (ABS). When braking, ABS controls the braking force through the valve body to prevent the wheels from locking and prevent them from rolling and sliding. This ensures maximum adhesion between the wheels and the ground, reducing the probability of rollover. Therefore, the performance of the ABS valve body directly affects the safety of the vehicle.

[0033] See Figure 1 , Figure 1 A structural schematic diagram of an automatic assembly device in an embodiment of the present application is shown. 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] See Figure 8 In some embodiments, an ABS valve body 10 includes a valve body, which is provided with a valve nozzle pressure port 11, a steel ball pressure port 12, and a gasket placement portion 13. These valve nozzle pressure port 11, steel ball pressure port 12, and gasket placement portion 13 are located at different positions on the valve body. It is understood that the gasket placement portion 13, steel ball pressure port 12, and valve nozzle pressure port 11 are holes or slots located at different positions on the valve body. Hereinafter, the "ABS valve body" will be referred to as a "workpiece."

[0036] Combine Figure 1 and Figure 2 As shown, in one embodiment, the automatic assembly device provided by the present application includes a loading mechanism 100, a gasket placement mechanism, a riveting mechanism 500, a pressing mechanism, a blanking mechanism 800, and a transfer component 900. The loading mechanism 100 is used to load 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 blanking 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, which are respectively 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 located at different positions. The first pressing mechanism 600 and the second pressing mechanism 700 are respectively equipped with a first rotating portion 660 and a second rotating portion 760. When the transfer component 900 transfers the workpiece 10 to the first pressing mechanism 600, the first rotating portion 660 is connected to the transfer component 900 and drives the workpiece 10 to rotate by a first preset angle, so that the first pressing mechanism 600 presses the steel ball toward the steel ball pressure opening 12. When the transfer component 900 transfers the workpiece 10 to the second pressing mechanism 700, the second rotating portion 760 is connected to the transfer component 900 and drives the workpiece 10 to rotate by a second preset angle, so that the second pressing mechanism 700 presses the valve nozzle 20 toward the valve nozzle pressure opening 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, combined with Figure 2As shown, the first rotating portion 660 is disposed opposite the riveting mechanism 500. This allows the workpiece 10 to 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 is understandable that the position of the first rotating portion 660 can be adjusted according to actual needs, that is, the first rotating portion 660 can also be disposed opposite the first pressing mechanism 600. In this way, after the workpiece 10 is transferred to the workstation of the first pressing mechanism 600, the first rotating portion 660 first flips the workpiece 10 at a first preset angle, and then the steel ball pressing operation is performed.

[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 undergoes 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 equipped with a first rotating portion 660 and a second rotating portion 760. This allows the workpiece 10 to be flipped at a predetermined angle to adjust the angles of the steel ball pressing opening 12 and the valve nozzle pressing opening 11 of the workpiece 10, thereby adapting to the pressing angle of the pressing mechanism, thereby achieving automated assembly of the steel ball pressing and the valve nozzle 20 pressing. Therefore, the automatic assembly device can achieve fully automated assembly, avoiding the uncertainties caused by manual assembly, improving product consistency and quality, and effectively increasing assembly efficiency.

[0039] Optionally, combined Figure 2 As shown, the automatic assembly device may include, but is not limited to, a vibration mechanism 1000, which is used to transport materials such as silencers, 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 tray.

[0041] Preferably, combined Figure 3As shown, 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 one by one 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 Figure 3 In FIG. 1 , only a schematic diagram of the structure of one of the clamps 910 is shown. The structures of the other clamps 910 are shown in FIG. Figure 3 The turntable 920 can rotate around the rotation center so that each clamp 910 can be transferred in sequence among 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.

[0043] Specifically, by arranging the various mechanisms at intervals around the rotation center of turntable 920, a circular layout of the various mechanisms is achieved. This helps save space and improves the structural compactness of the automatic assembly device. Furthermore, the workpieces 10 can be sequentially transferred and assembled simply by rotating turntable 920, resulting in a simple, reliable structure and easy control. Furthermore, 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 turntable 920, thus enabling uninterrupted production of workpieces 10 and improving 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. At this time, 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. Then, when the turntable 920 rotates one station angle, the assembly of one workpiece 10 can be completed and unloaded, and one workpiece 10 can be loaded, thus effectively improving the efficiency of assembly. 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 achieve the sequential assembly operation of the workpiece 10.

[0045] Optionally, combined Figure 2 and Figure 3As shown, the loading mechanism 100 may be, but is not limited to, provided with a third rotating portion 110. The third rotating portion 110 is used to connect with the clamp 910 and drive the clamp 910 to flip by a third preset angle to reset the clamp 910 to its initial state for clamping the workpiece 10. Specifically, the corresponding third rotating portion 110 is provided in the loading mechanism 100, so that the clamp 910 aligned with the loading mechanism 100 can be flipped and reset to facilitate the loading of the next workpiece 10 to be assembled, thereby improving the full automation of the automatic assembly.

[0046] Preferably, continue 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 the 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 is engaged with the second rotating member 1130, thereby realizing the angular flip 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 toward the second rotating member 1130, the joint of the first rotating member 1120 can engage with the slot of the second rotating member 1130. In this way, 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 achieving the angular 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 a 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, continue to refer to Figure 3The first rotating unit 660, the second rotating unit 760, and the third rotating unit 110 may each further include, but are not limited to, a positioner 1140. The positioner 1140 is used to position the flip angle of the workpiece 10, thereby helping to improve the accuracy of the flip angle of the workpiece 10. Optionally, the positioner 1140 may be implemented as, but is not limited to, a positioning sensor or a positioning lock.

[0050] More preferably, the positioner 1140 may be implemented, but is 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 second rotating member 1130 has at least two grooves 1130a evenly distributed on its circumferential surface around the first direction. The ball 1142 is configured 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 of the grooves 1130a, thereby achieving rotational positioning of the second rotating member 1130.

[0051] It should be noted that, during the assembly of an ABS valve body, the workpiece 10 generally needs to be flipped 90° during both the steel ball pressing and valve nozzle 20 pressing steps to accommodate the pressing angles of the first and second pressing mechanisms 600, 700. Therefore, preferably, the grooves 1130a are arranged at 45° intervals around the rotation center of the second rotating member 1130. This improves the positioning accuracy of the positioner 1140. Furthermore, after the steel ball pressing and valve nozzle 20 pressing steps, the workpiece 10 is flipped twice, for a total of 180°. Therefore, a third rotating portion 110 is also provided in the loading mechanism 100. This allows the fixture 910 to be flipped and reset before loading, thereby facilitating easier loading.

[0052] Optionally, combined Figure 4 As shown, 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 to feed steel balls. The conveying module 620 is used to transport the steel balls entering the feed port 610 and align them with the steel ball pressing port 12 of the workpiece 10. The first pressing rod 630 is used to press 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 hole 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 downward 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 can be monitored in real time, and the quality of the steel ball pressing can be judged by the pressure and displacement.

[0055] Optionally, combined Figures 6 to 8 As shown, 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 has a hollow cavity 720a and a gun muzzle 721. The second pressing rod 730 is telescopically arranged in the hollow cavity 720a. The gun muzzle 721 is adapted to the valve nozzle pressure port 11 of the workpiece 10 and is used to press the valve nozzle pressure port 11. The hollow cavity 720a is used to accommodate the valve nozzle 20. The second pressing rod 730 is 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 downward pressing 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 the outer contour and size, and the pressure gun 720 is hollow to accommodate 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, refer back to Figure 6The second pressing rod 730 is provided with a stopper 731, which is exposed from the pressing gun 720. The exposed portion of the stopper 731 serves as the allowable insertion depth of the second pressing rod 730. The allowable insertion depth is adapted to the insertion depth of the valve nozzle 20 of the workpiece 10 to be assembled. Thus, the insertion depth of the valve nozzle 20 can be controlled by controlling the exposed length of the stopper 731 of the second pressing rod 730. This arrangement allows the second pressing rod 730 to be adjusted to a suitable insertion depth. Consequently, when the second pressing rod 730 is pressed to the bottom by the pressing cylinder 710, the valve nozzle 20 is flush with the valve nozzle pressure opening 11, ensuring that the required tolerances are within the process, effectively improving assembly consistency and quality.

[0058] More preferably, continue to refer to Figure 6 In order to ensure the reliability of the downward pressing process of the valve nozzle 20, in some embodiments, the second downward pressing mechanism 700 also includes a second displacement sensor 740 and a second pressure sensor 750. The second displacement sensor 740 is used to monitor the downward 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 depth of the valve nozzle 20 being pressed 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 downward pressing of the valve nozzle 20.

[0059] Optionally, the automatic assembly device may, but is not limited to, further include an in-position sensor (not shown), which is used to monitor whether the workpiece 10 is in position in the fixture 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, so as to send an automatic assembly signal.

[0060] Preferably, the automatic assembly device may, but is not limited to, further 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 (workstation) 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 is capable of controlling the assembly operations 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-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.
