Description

Technical Field

[0001] This invention relates to the field of brake booster system assembly technology, and in particular to a piston cup assembly device for a brake booster system. Background Technology

[0002] The brake assist system is an important component of modern automotive braking systems. It is mainly used to reduce the force required by the driver when pressing the brake pedal, thereby improving the efficiency and stability of the braking system.

[0003] In the current technology, the production of automotive brake assist systems is mainly carried out by manual or semi-automatic assembly methods. With the continuous development and application of intelligent and automated technologies, automated assembly has become a trend in the manufacturing industry, with broad prospects and application value. The fully automated assembly of automotive brake assist systems has also become an effective means for current automakers to enhance competitiveness, reduce costs, and improve product quality.

[0004] During the assembly of the brake booster system, a lip cup needs to be installed inside the valve hole of the valve block to ensure its sealing performance. Currently, there are two main types of lip cup assembly: manual assembly and automatic machine assembly. Manual assembly is less efficient, while for machine assembly, since the lip cup itself is made of flexible material, it is easy to deform during the installation process, making it difficult to guarantee the installation accuracy, thereby affecting the working performance of the valve block itself. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a piston cup assembly device for brake booster systems that offers high assembly efficiency and ensures installation accuracy.

[0021] Further defining the above-mentioned diaphragm cup assembly device for a brake assist system, wherein the positioning component includes a positioning frame fixedly mounted on the assembly frame, a positioning block fixedly mounted on the positioning frame, and a placement groove for accommodating the diaphragm cup on the positioning block;

[0022] The positioning frame is also fixedly provided with a vertical positioning cylinder, a bidirectional telescopic mechanism, and a positioning vision sensor.

The cover plate is provided with a material picking hole. The two telescopic ends of the bidirectional telescopic mechanism are respectively fixedly provided with horizontal positioning plates. The opposite surfaces of the two horizontal positioning plates are respectively provided with positioning arc grooves.

[0023] The end face of the cover plate near the assembly frame can abut against the end face of the horizontal positioning plate away from the assembly frame. The diameter of the material picking hole is not greater than the diameter of the leather cup. The diameter of the placement groove is greater than the diameter of the leather cup. The opposite faces of the two horizontal positioning plates can abut against each other. The two positioning arc grooves can form an annular groove that is coaxial with the placement groove and matches the diameter of the leather cup when the two horizontal positioning plates abut against each other.

[0024] Further specifying, in the above-mentioned cup assembly device for a brake assist system, the positioning component further includes a top-pressure cylinder fixedly mounted on the positioning frame, a pressure head fixedly mounted on the telescopic end of the top-pressure cylinder, and a slot provided on the positioning block that communicates with the placement groove and can be inserted into the pressure head.

[0025] Further defining the above-mentioned cup assembly device for a brake assist system, the cup pressing assembly includes a robotic arm assembly fixedly mounted on the assembly frame and a gripping pressing assembly coupled to the robotic arm assembly.

[0026] The gripping and pressing assembly is installed at the output end of the robotic arm assembly, and the robotic arm assembly can drive the gripping and pressing assembly to rotate along its own axis or move horizontally or vertically.

[0027] Further defining the above-mentioned cup assembly device for a brake assist system, the gripping and pressing assembly includes a first connecting cylinder and a second connecting cylinder that are fixedly connected to the drive assembly of the robotic arm assembly and are respectively located on the side of the robotic arm assembly away from and close to the assembly frame.

[0028] A first gripping cylinder and a second gripping cylinder are fixedly connected to the first connecting cylinder. The second gripping cylinder is fixedly mounted on the first connecting cylinder, and the first gripping cylinder is fixedly mounted on the side of the second gripping cylinder away from the first connecting cylinder.

[0029] A transition shaft coaxial with the second connecting cylinder is fixedly connected to the telescopic end of the first gripping cylinder. The end of the transition shaft away from the first gripping cylinder passes through to the side of the robotic arm assembly near the second connecting cylinder and is fixedly provided with a limiting member. The end of the limiting member away from the adapter column is fixedly connected with a contour block coaxial with the second connecting cylinder through a fixing rod.

[0030] The molding block is located on the side of the second connecting cylinder away from the first connecting cylinder. The molding block has an arc shape with its outer peripheral surface partially concave towards the central axis and a gripping seat is fixed on the end face away from the limiting member.

The end of the guide plate away from the telescopic shaft can abut against the end of the driven swing plate away from the model block. The abutment surfaces between the guide plate and the driven swing plate are inclined surfaces and fit each other.

[0034] Wherein, when the first gripping cylinder is extended, the distance between the gripping sleeve and the gripping seat is greater than the axial height of the leather cup, and the leather cup can deform and fit the outer contour surface of the molding block under the action of the pressure head;

[0035] Under the action of the guide plate, the driven swing plate can swing away from the guide plate to the side away from the central axis of the model block and abut against the inner ring wall of the cup.

[0037] The assembly platform can slide along the transposition guide rail under the action of an external power device, and the valve block is mounted on the assembly platform.

[0038] This invention has at least the following beneficial effects:

[0039] 1. The feeding status of the leather cup is identified by the orientation adjustment component, thereby ensuring the accuracy of the leather cup assembly. At the same time, the transfer mechanism realizes the automated transfer of the leather cup between the orientation, oil spraying and positioning processes. While ensuring the assembly quality of the leather cup, the process cycle of the entire assembly process is greatly shortened. After the leather cup is positioned by the positioning component, the leather cup pressing component automatically grabs the leather cup and performs the pressing of the leather cup on the valve block, thereby realizing the fully automated assembly process of the leather cup, which not only reduces labor costs, but also greatly improves production efficiency.

[0040] 2. The cup pressing assembly and the positioning assembly work together to position the cup axially and circumferentially. The pressing head then presses against the cup to make it fit against the outer contour surface of the template block, thereby achieving the retraction of the cup. This allows the cup to smoothly enter the valve hole of the valve block during assembly. At the same time, during the pressing process, the driven swing plate swings to expand the inner ring surface of the cup, so that the cup can be completely embedded in the inner groove of the valve hole, ensuring the assembly stability of the cup and greatly improving the overall efficiency of the cup assembly.

Detailed Implementation

[0056] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0057] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0058] The following description, in conjunction with the accompanying drawings, details the piston cup assembly device for a brake assist system provided in this application through specific embodiments and application scenarios.

[0059] like Figures 1 to 13 As shown in the figure, this application provides a piston cup assembly device for a brake booster system, including an assembly frame 100, on which a valve block tooling, a piston cup feeding device, a steering adjustment assembly 500, an oil injection assembly 600, a transfer mechanism 700, a positioning assembly 800, and a piston cup pressing assembly are mounted.

[0060] The orientation adjustment component 500 is used to orient and adjust the leather cup 420 output by the leather cup feeding device. The oil spraying component 600 is used to spray oil around the leather cup 420 after orientation. The positioning component 800 is used to position the leather cup 420. The transfer mechanism 700 is used to transfer the stroke of the leather cup 420 between the orientation adjustment component 500, the oil spraying component 600, and the positioning component 800. The leather cup pressing component can grab the leather cup 420 after positioning on the positioning component 800 and press it into the valve hole of the valve block 410 on the valve block tooling.

[0061] Understandably, since the front and back sides of the diaphragm cup 420 need to be distinguished during the assembly of the valve block 410, the front and back sides of the diaphragm cup 420 need to be controlled after it is output by the diaphragm cup feeding device. Specifically, the orientation adjustment component 500 can identify the front and back sides of the diaphragm cup 420 at the identification station. When the diaphragm cup 420 is identified as being in the wrong orientation, it will be flipped over and then transferred to the oil injection station of the oil injection component 600 through the transfer mechanism 700. When the diaphragm cup 420 is identified as being in the correct orientation, it will be directly transferred to the oil injection station of the oil injection component 600 through the transfer mechanism 700.

[0062] like Figure 3 As shown, the valve hole of the valve block 410 is provided with an inner groove 411. The cup 420 can be embedded in the inner groove 411 to ensure the sealing of the valve hole of the valve block 410. Since the diameter of the cup 420 is larger than the diameter of the valve hole of the valve block 410, when the cup pressing assembly grabs the cup 420, it can shrink the cup 420 and then drive the cup 420 into the valve hole of the valve block 410 and roll the cup 420 into the inner groove 411 in the circumferential direction.

[0063] In this embodiment, the aforementioned piston cup assembly device for the brake booster system is used. The orientation adjustment component 500 identifies the feeding status of the piston cup 420, thereby ensuring the accuracy of the piston cup 420 assembly. At the same time, the transfer mechanism 700 realizes the automated transfer of the piston cup 420 between the orientation, oil injection, and positioning processes. While ensuring the assembly quality of the piston cup 420, the process cycle of the entire assembly process is greatly shortened. After the piston cup 420 is positioned by the positioning component 800, the piston cup pressing component automatically grasps the piston cup 420 and performs pressing of the piston cup 420 onto the valve block 410, thereby realizing the fully automated assembly process of the piston cup 420, which not only reduces labor costs but also greatly improves production efficiency.

[0064] It is understandable that the reason for spraying oil on the circumference of the cup 420 through the oil spraying assembly 600 is that during the process of the cup pressing assembly driving the cup 420 to press into the inner groove 411, the outer circumferential surface of the cup 420 will come into contact with the inner wall of the valve hole of the valve block 410. Under the action of friction, the position of the cup 420 may be affected. By spraying oil on the circumferential surface of the cup 420, the friction between it and the inner wall of the valve hole of the valve block 410 can be reduced, thereby reducing the impact of friction on the installation accuracy of the cup 420.

[0065] Of course, if the pressure fitting assembly can ensure that the outer circumferential surface of the cup 420 does not come into contact with the inner wall of the valve hole of the valve block 410 after the cup 420 shrinks, or if the friction between the cup 420 and the inner wall of the valve hole of the valve block 410 is within an acceptable range, then the oil injection assembly 600 can be discarded accordingly, that is, the oil injection process for the cup 420 can be cancelled.

[0066] In a preferred embodiment, such as Figure 1 , Figure 2 As shown, the valve block tooling includes a shift guide rail 310 fixedly mounted on the assembly frame 100, and an assembly table 320 slidably mounted on the shift guide rail 310.

[0067] The assembly table 320 can slide along the transposition guide rail 310 under the action of an external power device, and the valve block 410 is installed on the assembly table 320 when assembling the diaphragm cup 420.

[0068] It is understandable that the valve block tooling setup is not limited to the one described above. The valve block tooling setup described above is suitable for assembly line operation environments. If the cup assembly device is an independent workstation, the valve block 410 can be directly installed at a fixed assembly station, which will not be elaborated here.

[0069] In a preferred embodiment, such as Figure 1 , Figure 2As shown, the leather cup feeding device includes a feeding bin 210 fixedly installed on the assembly frame 100. A vibrating feeding component 220 is installed on the bottom wall of the feeding bin 210. The discharge end of the vibrating feeding component 220 extends to the orientation station of the orientation adjustment component 500.

[0070] It is understandable that the vibrating feeding component 220 can transfer the leather cup 420 in the feeding bin 210 to the orientation adjustment component 500, and the orientation adjustment component 500 can realize the forward and reverse orientation of the leather cup 420 output by the leather cup feeding device.

[0071] It is understandable that the leather cup feeding device is mainly used to transfer the leather cup 420 to the orientation adjustment component 500 orientation station. Its structure is not limited to the one mentioned above. For example, it can also use turntable feeding, belt feeding, robot feeding, etc., as long as the feeding action of the leather cup 420 can be realized. No specific restrictions are made here.

[0072] In a preferred embodiment, such as Figure 4 As shown, the orientation adjustment assembly 500 includes a first fixed seat 510 fixedly mounted on the assembly frame 100. A telescopic cylinder 511 and an orientation vision sensor 513 are fixedly mounted on the first fixed seat 510. A feeding plate 512 is fixedly mounted on the telescopic end of the telescopic cylinder 511. The feeding plate 512 is provided with a receiving groove for accommodating the output cup 420 of the cup feeding device.

[0073] The orientation adjustment assembly 500 also includes a second fixed seat 520 fixedly mounted on the assembly frame 100. An electric slide 521 capable of moving toward or away from the feeding plate 512 is mounted on the second fixed seat 520. A reversing motor 522 is fixedly mounted on the electric slide 521, and an electric gripper 523 is mounted on the output end of the reversing motor 522.

[0074] When the telescopic cylinder 511 is in the retracted state, the receiving groove on the feeding plate 512 corresponds to the output end of the cup feeding device, that is, the cup 420 output by the cup feeding device can fall directly into the receiving groove on the feeding plate 512; when the telescopic cylinder 511 is in the extended state, the receiving groove on the feeding plate 512 corresponds to the position of the electric gripper 523.

[0075] Specifically, in the initial state, the telescopic cylinder 511 is in the retracted state, and the electric slide table 521 is located at the end away from the feeding plate 512 during the sliding stroke. When the cup 420 output by the cup feeding device falls into the receiving groove on the feeding plate 512, the orientation vision sensor 513 can perform front and back vision detection on the cup 420 in the receiving groove of the feeding plate 512. If the orientation of the cup 420 is correct, it is directly transferred to the oil spraying station of the oil spraying assembly 600 through the transfer mechanism 700. If the orientation of the cup 420 is incorrect, the telescopic cylinder 511 extends. When the telescopic cylinder 511 is fully extended, the electric slide table 521 drives the reversing motor 522 and the electric gripper 5 23 moves towards the side closer to the feeding plate 512, and the electric gripper 523 clamps the cup 420 in the receiving groove of the feeding plate 512. The electric slide 521 moves away from the feeding plate 512 to leave adjustment space for the electric gripper 523. Driven by the reversing motor 522, the electric gripper 523 flips the cup 420 180°. After the cup 420 is flipped, the electric slide 521 moves towards the side closer to the feeding plate 512 and the electric gripper 523 puts the cup 420 back into the receiving groove on the feeding plate 512. The telescopic cylinder 511 and the electric slide 521 are reset. Then, the cup 420 is transferred to the oil spraying station of the oil spraying assembly 600 through the transfer mechanism 700.

[0076] It is understandable that the structure of the orientation adjustment component 500 is not limited to the one mentioned above. For example, a clamping and flipping mechanism can be set directly at the alignment position of the receiving groove on the feeding plate 512. On the other hand, the orientation adjustment component 500 can also be integrated into the leather cup feeding device to directly realize forward and reverse orientation during the feeding process of the leather cup 420.

[0077] Understandably, the orientation adjustment component 500 is mainly used to identify and adjust the orientation of the leather cup 420. However, based on the structure of the leather cup feeding device, when the leather cup feeding device adopts semi-automatic feeding, that is, the orientation of the leather cup is adjusted manually in advance, the orientation adjustment component 500 can be discarded accordingly.

[0078] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 4 As shown, the fuel injection assembly 600 includes a fuel injection bracket 610 fixedly mounted on the assembly frame 100, and a fuel injector 620 fixedly mounted on the fuel injection bracket 610.

[0079] Understandably, the fuel injection bracket 610 is provided with an oil receiving groove and a drain pipe for discharging oil from the fuel receiving groove at the fuel injection position of the fuel injector 620.

[0080] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 5 As shown, the transfer mechanism 700 includes a support frame 710 fixedly mounted on the assembly frame 100, a transverse slide rail 720 fixedly mounted on the support frame 710, a transfer slide 730 slidably mounted on the transverse slide rail 720, a lifting cylinder 740 fixedly mounted on the transfer slide 730, a lifting slide 750 fixedly mounted on the output end of the lifting cylinder 740, a steering motor 760 fixedly mounted on the lifting slide 750, and an inner support gripping head 770 fixedly mounted on the output end of the steering motor 760.

[0081] Understandably, the transfer slide 730 can move along the length of the transverse slide rail 720 under the action of an external power device, thereby driving the steering motor 760 and the inner support gripper head 770 to move synchronously.

[0082] The orientation station of the orientation adjustment component 500, the oil injection station of the oil injection component 600, and the positioning station of the positioning component 800 are all located on the moving trajectory of the inner support gripper head 770. Initially, the transfer slide 730 is located on the side of the transverse slide rail 720 near the positioning component 800, and the lifting cylinder 740 is in a retracted state. After the orientation adjustment component 500 completes the orientation of the diaphragm cup 420, the transfer slide 730 moves along the transverse slide rail 720 to the orientation station of the orientation adjustment component 500. The lifting cylinder 740 extends and performs an inner support gripping of the diaphragm cup 420 at the orientation station through the inner support gripper head 770. Then, the lifting cylinder 740 retracts to reset. The transfer slide 730 moves along the transverse slide rail 720 to the oil injection station of the oil injection assembly 600. The lifting cylinder 740 extends again until the piston cup 420 corresponds to the position of the oil injector 620. At this time, the oil injector 620 is activated, and the steering motor 760 drives the inner support gripper head 770 to rotate to achieve oil injection on the circumference of the piston cup 420. After the piston cup 420 is finished being injected, the transfer slide 730 moves along the transverse slide rail 720 to the positioning station of the positioning assembly 800. The lifting cylinder 740 lifts and lowers the inner support gripper head 770 to place the piston cup 420 at the positioning station of the positioning assembly 800. Finally, all components of the transfer mechanism 700 are reset to execute the next work cycle.

[0083] It is understandable that the process station settings of the orientation adjustment component 500, the oil injection component 600, and the positioning component 800 are not limited to the above one. Based on the overall layout of the assembly device, the orientation, oil injection, and positioning stations of the cup 420 can be set to a non-linear distribution, thereby improving the compactness of the device. At this time, the transfer mechanism 700 needs to increase the horizontal movement freedom of the inner support gripper head 770, so as to ensure that the inner support gripper head 770 can transfer the cup 420 between multiple stations. Specifically, it can be set to replace the transmission form between the transverse slide rail 720 and the transfer slide 730 with a horizontal X and Y dual-axis slide. Through the driving in two directions on the horizontal plane, the coordinates of the inner support gripper head 770 can be flexibly transferred on the horizontal plane, thereby improving the overall adaptability of the device.

[0084] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, the positioning component 800 includes a positioning frame 801 fixedly mounted on the assembly frame 100, a positioning block 810 fixedly mounted on the positioning frame 801, and a placement groove 813 for accommodating the leather cup 420 on the positioning block 810.

[0085] The positioning frame 801 is also fixedly equipped with a vertical positioning cylinder 802, a top pressing cylinder 807, and a positioning vision sensor 809. The telescopic end of the vertical positioning cylinder 802 is fixedly equipped with a cover plate 803 located on the side of the positioning block 810 away from the assembly frame 100. The cover plate 803 is provided with a material picking hole 804. The telescopic end of the top pressing cylinder 807 is fixedly equipped with a pressure head 808. The positioning block 810 is provided with a slot 812 that is connected to the placement groove 813 and can be inserted into the pressure head 808.

[0086] The positioning frame 801 is also fixedly provided with a bidirectional telescopic mechanism 805. Horizontal positioning plates 806 are fixedly provided on the two telescopic ends of the bidirectional telescopic mechanism 805, and positioning arc grooves 811 are provided on the opposite surfaces of the two horizontal positioning plates 806.

[0087] Among them, the end face of the cover plate 803 near the assembly frame 100 can abut against the end face of the horizontal positioning plate 806 away from the assembly frame 100, the diameter of the material picking hole 804 is not greater than the diameter of the cup 420, the diameter of the placement groove 813 is greater than the diameter of the cup 420, and the opposite faces of the two horizontal positioning plates 806 can abut against each other. At this time, the two positioning arc grooves 811 form an annular groove that is coaxial with the placement groove 813 and matches the diameter of the cup 420.

[0088] Initially, the vertical positioning cylinder 802 and the top pressing cylinder 807 are in the retracted state, the cover plate 803 does not cover the placement groove 813, the two telescopic ends of the bidirectional telescopic mechanism 805 are in the extended state, and the two horizontal positioning plates 806 are not in contact with and do not cover the placement groove 813. When the transfer mechanism 700 places the cup 420 in the placement groove 813, the positioning vision sensor 809 senses the placement state of the cup 420, the two telescopic ends of the bidirectional telescopic mechanism 805 retract, the two horizontal positioning plates 806 abut with and encircle the outer circumference of the cup 420 in the placement groove 813 through the annular groove formed by the two positioning arc grooves 811, so that the cup 420 is completely centered in the placement groove 813. The vertical positioning cylinder 802 extends and drives the cover plate 803 to cover the positioning block 810, and the material picking hole 804 is coaxial with the placement groove 813, thereby limiting the axial displacement of the cup 420 in the placement groove 813.

[0089] like Figure 1 , Figure 2 , Figure 6 , Figures 8 to 13 As shown, the cup pressing assembly includes a robotic arm assembly 910 fixedly mounted on the assembly frame 100 and a gripping pressing assembly 920 coupled to the robotic arm assembly 910.

[0090] Among them, the robotic arm assembly 910 adopts a dual-arm four-axis robot structure, and the gripping and pressing assembly 920 is installed at the output end of the robotic arm of the robotic arm assembly 910. The robotic arm assembly 910 can drive the gripping and pressing assembly 920 to move horizontally or vertically, or rotate along its own axis.

[0091] The gripping and pressing assembly 920 includes a first connecting cylinder 921 and a second connecting cylinder 922, which are fixedly connected to the drive assembly of the robotic arm assembly 910 and located on the side of the robotic arm assembly 910 away from and near the assembly frame 100, respectively. A first gripping cylinder 925 and a second gripping cylinder 926 are fixedly connected to the first connecting cylinder 921. Specifically, the second gripping cylinder 926 is fixedly mounted on the first connecting cylinder 921, and a connecting bracket 924 is fixedly mounted on the side of the second gripping cylinder 926 away from the first connecting cylinder 921. The first gripping cylinder 925 is fixedly mounted on the side of the connecting bracket 924 away from the second gripping cylinder 926.

[0092] A connecting rod 927 is fixedly provided on the telescopic end of the first gripping cylinder 925. A transition shaft 929 is fixedly provided on the side of the connecting rod 927 away from the first gripping cylinder 925. A connecting post 930 is fixedly provided on the side of the robotic arm assembly 910 near the second connecting cylinder 922. A limiting member 931 is fixedly provided on the side of the connecting post 930 away from the transition shaft 929. A fixing rod 932 that passes through the second connecting cylinder 922 is fixedly provided on the side of the limiting member 931 away from the connecting post 930. A contour block 935 is fixedly provided on the side of the fixing rod 932 away from the limiting member 931. A gripping seat 936 is fixedly provided on the end face of the contour block 935 away from the fixing rod 932.

[0093] The telescopic end of the second gripping cylinder 926 is fixedly provided with a telescopic shaft 928 that passes through the transition shaft 929 and the adapter post 930. The telescopic shaft 928 is fixedly provided with a guide plate 933 that is in communication with and slidably connected to the limiting member 931 on the side away from the second gripping cylinder 926.

[0094] It is understandable that the telescopic ends of the first gripping cylinder 925 and the second gripping cylinder 926 are coaxial, and the transition shaft 929, the adapter column 930, the telescopic shaft 928, and the second connecting cylinder 922 are all coaxial.

[0095] The model block 935 has an arc shape with a partial inward concavity of the outer circular surface towards the axis. The inner cylinder arm of the second connecting cylinder 922 is hinged with a driven swing plate 934 located at the concave position of the model block 935. The side of the guide plate 933 away from the telescopic shaft 928 can abut against the side of the driven swing plate 934 away from the model block 935. The abutment surfaces between the guide plate 933 and the driven swing plate 934 are inclined surfaces and fit each other.

[0096] The second connecting sleeve 922 is fixedly fitted with a gripping sleeve 923 on the side near the model block 935. The gripping sleeve 923 has a first circumferential groove 937 on the side near the model block 935. The gripping seat 936 has a second circumferential groove 938 that matches the first circumferential groove 937 on the side near the model block 935.

[0097] The gripper 936 also has a travel groove 939 at the concave position of the model block 935, and the driven swing plate 934 and the pressure head 808 can slide in the travel groove 939.

[0098] The working principle of the leather cup pressing assembly is as follows:

[0099] Initially, the first gripping cylinder 925 is in the extended state, the distance between the gripping sleeve 923 and the gripping seat 936 is greater than the axial height of the leather cup 420, the second gripping cylinder 926 is in the retracted state, the guide plate 933 does not contact the driven swing plate 934, and the driven swing plate 934 can swing along the hinge axis inside the second connecting cylinder 922.

[0100] During the gripping process, the robotic arm assembly 910 moves the gripping and pressing assembly 920 to the positioning station of the positioning assembly 800. The robotic arm assembly 910 then lowers the gripping and pressing assembly 920, and the gripping seat 936 is inserted into the material picking hole 804, with the molding block 935 located at the inner ring of the cup 420. The pressure head 808 is positioned at the corresponding position of the concave part of the molding block 935. At this time, the top pressure cylinder 807 extends, driving the pressure head 808 to insert into the slot 812 and abut against the outer circumferential surface of the cup 420. As the pressure head 808 inserts into the concave part of the molding block 935, the cup 420 deforms under the abutment of the pressure head 808 to conform to the outer contour surface of the molding block 935. The driven swing plate 934 swings towards the molding block under the abutment of the cup 420. In the concave portion of 935, the first gripping cylinder 925 retracts, and through the connecting rod 927, transition shaft 929, connecting column 930, limiting member 931, and fixing rod 932, it drives the molding block 935 and gripping seat 936 to move closer to the first circumferential groove 937. As the distance between the gripping seat 936 and the gripping sleeve 923 decreases, the cup 420 sleeved on the molding block 935 is clamped axially by the gripping sleeve 923 and gripping seat 936. At the same time, under the circumferential limiting action of the first circumferential groove 937 and the second circumferential groove 938, the cup 420 is contracted within the limiting space formed by the first circumferential groove 937 and the second circumferential groove 938. At this time, the positioning component 800 resets and waits for the next positioning cycle.

[0101] During pressing, the robotic arm assembly 910 drives the gripping and pressing assembly 920 to rise and move to the corresponding position of the valve hole of the valve block 410. Then, the robotic arm assembly 910 drives the gripping and pressing assembly 920 to descend, the gripping seat 936 extends into the valve hole of the valve block 410 and the profile block 935 is located at the corresponding position of the inner groove 411. The first gripping cylinder 925 extends and resets, the axial and circumferential limits of the cup 420 sleeved on the profile block 935 are released, and under its own elastic force, the cup 420 restores its shape and is embedded. The second gripping cylinder 926 extends and drives the guide plate 933 to abut against the driven swing plate 934 through the telescopic shaft 928. Under the action of the guide plate 933, the driven swing plate 934 swings outward at the end away from the guide plate 933 and abuts against the inner ring wall of the cup 420. At this time, the robotic arm assembly 910 drives the gripping and pressing assembly 920 to rotate. Under the action of the driven swing plate 934 at the end away from the guide plate 933, the cup 420 is fully rolled into the corresponding inner hole groove 411.

[0102] After the leather cup 420 is pressed, the robotic arm assembly 910 and the gripping and pressing assembly 920 return to their initial state, waiting for the next gripping and pressing cycle.

[0103] It is understandable that the positioning component 800 is configured to limit the circumferential movement of the cup 420 by two horizontal positioning plates 806 and limit the axial movement of the cup 420 by the cover plate 803. This is because the cup 420 itself is made of flexible material, and the cup 420 is very easy to deform during the contact between the pressure head 808 and the outer circumferential surface of the cup 420. This results in poor fit between the cup 420 and the molding block 935, which in turn affects the final pressing accuracy of the cup 420 in the inner hole groove 411.

[0104] In this embodiment, the above-mentioned cup assembly device for a brake assist system is used. The cup pressing assembly and the positioning assembly 800 cooperate with each other. After positioning the cup 420 axially and circumferentially, the pressure head 808 abuts against the cup 420 to make it fit against the outer contour surface of the profile block 935, thereby realizing the retraction of the cup 420. This allows it to smoothly enter the valve hole of the valve block 410 during the assembly process. At the same time, during the pressing process of the cup 420, the driven swing plate 934 swings to expand the inner ring surface of the cup 420, so that the cup 420 can be completely embedded in the inner groove 411 in the valve hole, ensuring the assembly stability of the cup 420 and greatly improving the overall assembly efficiency of the cup 420.
