Description

Technical Field

[0001] This invention relates to the field of ABS valve production equipment technology, and more specifically, to an ABS valve accumulator piston assembly device. Background Technology

[0002] The ABS valve is an important component of the automotive anti-lock braking system. When assembling the ABS valve, an accumulator piston needs to be installed on it. Currently, the process of installing the accumulator piston onto the ABS valve is done manually, which results in low assembly efficiency of the accumulator piston and the ABS valve, and makes it difficult to guarantee the assembly quality of the accumulator piston and the ABS valve. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an ABS valve accumulator piston assembly device, which can assemble the accumulator piston onto the ABS valve in a mechanized manner, thereby improving the assembly efficiency of the accumulator piston and the ABS valve and ensuring the assembly quality of the accumulator piston and the ABS valve.

[0004] This invention provides an ABS valve accumulator piston assembly device, including a frame and a conveyor line, a material handling assembly, a transport assembly, an airtightness testing assembly, and an accumulator piston assembly assembly connected to the frame. A carrier plate is movably mounted on the conveyor line, which carries the accumulator piston and the ABS valve. The material handling assembly transfers the ABS valve with the accumulator piston to be assembled from the carrier plate to the transport assembly and transfers the ABS valve with the accumulator piston assembled from the transport assembly to the carrier plate. The transport assembly feeds the ABS valve into and removes the ABS valve from the airtightness testing assembly. The accumulator piston assembly assembly acquires the accumulator piston from the carrier plate and assembles it onto the ABS valve located on the transport assembly. The airtightness testing assembly tests the airtightness of the ABS valve before and after the accumulator piston assembly.

[0005] This invention enables the accumulator piston to be mechanically assembled onto the ABS valve, thereby improving the assembly efficiency of the accumulator piston and the ABS valve and ensuring the assembly quality of the accumulator piston and the ABS valve. Furthermore, the airtightness detection component can detect the airtightness of the ABS valve before and after the accumulator piston is assembled, thereby verifying the airtightness of the ABS valve before and after the accumulator piston is assembled to determine whether the accumulator piston has been reliably assembled.

[0006] In one possible implementation, the pick-and-place assembly includes a three-axis moving unit, a rotating seat, a pneumatic gripper, and a first cylinder. The three-axis moving unit is fixed to the frame, the rotating seat is rotatably connected to the drive end of the three-axis moving unit, the pneumatic gripper is fixed to the rotating seat and used to grip the ABS valve, and the first cylinder is rotatably connected to the drive end of the three-axis moving unit. The piston rod of the first cylinder is rotatably connected to the rotating seat, and the rotation centers of the rotating seat and the piston rod of the first cylinder are eccentrically set with respect to the rotation centers of the rotating seat and the drive end of the three-axis moving unit. The three-axis moving unit is used to drive the pneumatic gripper to move in the front-back, left-right, and up-down directions, and the first cylinder is used to drive the pneumatic gripper to rotate. By using this pick-and-place assembly, when the pick-and-place assembly needs to transfer the ABS valve with the accumulator piston to be assembled from the carrier plate to the conveying assembly, firstly, the three-axis moving unit controls the pneumatic gripper to move to the position of the ABS valve located above the carrier plate, then the pneumatic gripper grips the ABS valve located above the carrier plate, and then the first cylinder... The cylinder controls the rotating seat to rotate, causing the ABS valve held by the pneumatic gripper to change direction. Then, the three-axis moving unit controls the pneumatic gripper to move to the location of the transport assembly. After the transport assembly clamps the ABS valve, the pneumatic gripper releases the ABS valve. When the material handling assembly needs to transfer the ABS valve after assembling the accumulator piston from the transport assembly to the carrier plate, firstly, the three-axis moving unit controls the pneumatic gripper to move to the location of the transport assembly. Then, the pneumatic gripper clamps the ABS valve located on the transport assembly. Next, the three-axis moving unit controls the pneumatic gripper to move above the carrier plate. Then, the first cylinder controls the rotating seat to rotate and reset, causing the ABS valve held by the pneumatic gripper to change direction. Finally, the pneumatic gripper releases the ABS valve to place the ABS valve after assembling the accumulator piston onto the carrier plate. Furthermore, the aforementioned three-axis moving unit is a conventional displacement unit currently on the market. It can be implemented through a slide rail and cylinder drive, or through a slide rail and servo motor drive. This is existing technology and will not be elaborated upon here.

[0007] In one possible implementation, the handling assembly includes a first two-axis moving unit, a clamping fixture, and a rotary clamping cylinder. The first two-axis moving unit is fixed to the frame, the clamping fixture is fixed to the drive end of the first two-axis moving unit, and the rotary clamping cylinder is fixed to one side of the clamping fixture. The rotary clamping cylinder is used to clamp the ABS valve onto the clamping fixture, and the first two-axis moving unit is used to drive the ABS valve clamped on the clamping fixture to move back and forth and up and down. By using this handling assembly, the rotary clamping cylinder can clamp the ABS valve onto the clamping fixture. After the rotary clamping cylinder and the clamping fixture cooperate to clamp the ABS valve, under the action of the first two-axis moving unit, the first two-axis moving unit can send the ABS valve into the airtightness testing assembly or remove the ABS valve from the airtightness testing assembly. The aforementioned first two-axis moving unit is a conventional displacement unit currently on the market. It can be implemented by a slide rail and cylinder drive, or by a slide rail and servo motor drive. This is prior art and will not be described in detail here.

[0008] In one possible implementation, the airtightness testing assembly includes a test platform, a pressure block, and a second cylinder. The test platform is fixed on a frame and connected to an airtightness testing instrument. The second cylinder is fixed on the frame and used to drive the pressure block to move up and down. The pressure block is fixed on the drive end of the second cylinder. When the transport assembly moves the ABS valve between the pressure block and the test platform, the second cylinder drives the pressure block to move down to press the ABS valve onto the test platform. The airtightness testing instrument then tests the airtightness of the ABS valve via the test platform. By using this airtightness testing assembly, when the transport assembly moves the ABS valve between the pressure block and the test platform, the second cylinder can drive the pressure block to move down to press the ABS valve onto the test platform. At this time, the airtightness testing instrument can test the airtightness of the ABS valve via the test platform. After the airtightness test of the ABS valve is completed, the second cylinder can drive the pressure block to move up and reset, and the transport assembly can remove the ABS valve from the airtightness testing assembly.

[0009] In one possible implementation, the accumulator piston assembly includes a second two-axis moving unit, a support base, and two suction nozzles spaced apart. The second two-axis moving unit is fixed to the frame and drives the support base and the two suction nozzles to move back and forth and up and down. The support base is fixed to the drive end of the second two-axis moving unit. The two suction nozzles are movably inserted into the support base and can move up and down relative to the support base. Each suction nozzle located above the support base has a spring sleeved on its exterior. The lower end of each spring abuts against the upper surface of the support base, and the upper end of each spring abuts against the upper end of the corresponding suction nozzle. Two third cylinders are also fixed to the drive end of the second two-axis moving unit. The two third cylinders are vertically aligned with the two suction nozzles, and a gap is left between the drive end of each third cylinder and the upper end of the corresponding suction nozzle. The suction nozzles are used to pick up the accumulator piston located on the carrier plate, and the second two-axis moving unit is used to drive the suction nozzles to move above the conveying assembly. The drive end of the third cylinder is used to press down the suction nozzle so that the suction nozzle presses the accumulator piston onto the ABS valve located on the transport assembly. After assembling the accumulator piston assembly, the second two-axis moving unit first drives the suction nozzle to move it above the carrier plate. Then, the suction nozzle picks up the accumulator piston located on the carrier plate. Next, the second two-axis moving unit drives the suction nozzle to move it above the ABS valve located on the transport assembly. Immediately afterward, the drive end of the third cylinder presses down the suction nozzle so that the suction nozzle presses the accumulator piston onto the ABS valve located on the transport assembly. Finally, the suction nozzle releases the accumulator piston and the drive end of the third cylinder retracts. At this time, the suction nozzle can move upward and reset under the action of the spring. The above-mentioned second two-axis moving unit is a conventional displacement unit currently on the market. It can be implemented by sliding rail and cylinder drive, or by sliding rail and servo motor drive. It is existing technology and will not be described in detail here.

[0010] In one possible implementation, the ABS valve accumulator piston assembly device further includes a push assembly, which includes a movable seat, a fourth cylinder, and two push cylinders spaced back-to-back. The movable seat is movably connected to the frame, the fourth cylinder is fixed to the frame, the movable seat is fixed to the drive end of the fourth cylinder, and both push cylinders are fixed to the movable seat. The fourth cylinder drives the movable seat to move back and forth so that the two push cylinders are aligned left and right with the ABS valve located on the transport assembly, and the two push cylinders are used to press the ABS valve against the transport assembly. With the push assembly in place, when the airtightness testing assembly performs an airtightness test on the ABS valve located on the transport assembly, the fourth cylinder first drives the movable seat to move backward so that the two push cylinders are aligned left and right with the ABS valve located on the transport assembly, and then the drive ends of the two push cylinders extend to press the ABS valve against the transport assembly. After the ABS valve airtightness test is completed, the drive ends of the two push cylinders retract and reset to release the clamping state on the ABS valve. When the accumulator piston assembly assembly assembles the accumulator piston onto the ABS valve, the fourth cylinder first drives the moving seat to move forward so that the two push cylinders are aligned left and right with the ABS valve located on the transport assembly. Then, the drive ends of the two push cylinders extend to clamp the ABS valve onto the transport assembly. After the ABS valve completes the accumulator piston assembly, the drive ends of the two push cylinders retract and reset to release the clamping state on the ABS valve. Since the push assembly can clamp the ABS valve on the transport assembly when it is in the airtightness test state and when it is in the accumulator piston assembly state, the reliability of the transport assembly clamping the ABS valve can be improved when the ABS valve is in the airtightness test state and when it is in the accumulator piston assembly state.
