Description

Technical Field

[0001] This invention relates to the field of air spring controller assembly equipment, and more specifically to a solenoid valve press-fitting device for an air suspension system. Background Technology

[0002] Air suspension systems use air springs as elastic elements, leveraging the compressibility of gas to achieve their elastic effect. The compressed gas pressure automatically adjusts according to changes in load and road conditions. In this system, the controller is a crucial electrical component, containing solenoid valves. During solenoid valve assembly, pressure sensors need to be installed on the valve seats. To facilitate the press-fitting of these pressure sensors, a pneumatic press-fitting method is currently employed. For example, Chinese utility model patent CN219704078U discloses a dual-pressure sensor air nozzle end cap press-fitting device, including a base plate, a base mounted on the base plate, and the base plate positioned behind the base. The device has a support frame, with a base plate on each side of the base, containing a left clamping cylinder and a right clamping cylinder respectively. The base has an upward-facing product placement slot, and the support frame has a lifting cylinder. The piston of the lifting cylinder has a pressure head that moves with it, and the pressure head is fitted to the upper surface of the end cap to be pressed. The piston of the left clamping cylinder has a left clamping block that moves along the X-axis, and the piston of the right clamping cylinder has a right clamping block that moves along the X-axis. The right end of the left clamping block has a left clamping notch that fits the product, and the left end of the right clamping block has a right clamping notch that fits the product. Both the left and right clamping notches fit the outer wall of the end cap to be pressed. However, this type of equipment has the following problems: 1. Low automation; loading and unloading of parts requires manual labor; 2. The relatively rigid pressing method used in this type of equipment may cause deformation of the pressure sensor surface or over-pressing of components, affecting installation accuracy.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. In this invention, a conveyor belt transports a transfer fixture containing a valve seat to a robotic arm. The robotic arm clamps the valve seat onto a material platform. A sliding feeding assembly moves the material platform below the pressing main frame. A pressure sensor feeding mechanism moves a material tray containing a pressure sensor to the feeding position. The robotic arm moves the pressure sensor to a sensor detection mechanism, where both ends of the pressure sensor are inspected for quality. After inspection, the pressure sensor is then transferred to the material platform via a removal component within the sensor detection mechanism. Through the combined operation of multiple mechanisms, the valve seat is lifted during pressure sensor installation. The automation level is increased, reducing the intensity of manual labor. During the press-fitting of the pressure sensor, the press-fitting power component is activated and drives the elastic pressing assembly and the press-fitting seat to move downward. The elastic pressing assembly first contacts the valve seat of the solenoid valve, and the press-fitting power component continues to drive the press-fitting seat to move downward. The flexible pressing top is fitted onto the pressure sensor. During press-fitting, the flexible pressing top will retract upward, and the pressure sensor is stably installed on the valve body of the solenoid valve. The pressure sensor is press-fitted in a flexible manner, reducing the surface deformation of the pressure sensor surface, improving the adaptability of the pressure sensor when it is inserted into the valve body, and ensuring installation accuracy.

[0016] 2. In the pressure sensor feeding mechanism, the material is fed through the lower fixed feeding slide, and then the material tray is sent to the positioning component through the lifting component. The robotic arm grabs the pressure sensor, and then the empty material tray is removed from the discharge movable slide. The feeding and discharging are set up in upper and lower layers, which makes the material picking space sufficient and the space layout reasonable, which helps to improve work efficiency.

[0017] 3. In the sensor detection mechanism, the suction component mainly uses negative pressure to pick up the pressure sensor. Compared with the gripping method of the robotic arm, this method can effectively avoid the deformation caused by gripping and play a better role in protecting the pressure sensor.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0032] Example: A solenoid valve press-fitting device for an air suspension system, including a workbench 1, as shown in the attached document. Figure 1 As shown, a conveyor belt 2 is installed at one end of the workbench 1, and a transfer fixture 3 for placing valve seats is installed on the conveyor belt 2. After the transfer fixture reaches the loading position, the lifting mechanism will lift the transfer fixture and the transfer fixture will detach from the conveyor belt. A robotic arm 4 for material movement is installed in the middle of the workbench 1. The movable end of the robotic arm has a pneumatic gripper, which can grip the valve seat of the solenoid valve to realize the loading. A pressure sensor loading mechanism 5 is installed at the other end of the workbench 1. A sensor detection mechanism 6 and a pressing mechanism 7 are also installed on the workbench 1. The sensor detection mechanism 6, the pressing mechanism 7 and the pressure sensor loading mechanism 5 are arranged around the robotic arm 4.

[0033] Below the pressing mechanism 7 is a sliding feeding assembly 8, and a material platform 9 for placing valve seats is installed on the moving end of the sliding feeding assembly 8; the pressing mechanism 7 includes a pressing main frame 91 set on the workbench 1, and a pressing power component 92 is installed on the pressing main frame 91. The pressing power component mainly consists of a screw and a sliding sleeve. The screw is driven to rotate by a motor to realize the lifting and lowering of the sliding sleeve. The seat body connected to the sliding sleeve is lifted and lowered. At the same time, the seat body is connected to the pressing main frame through a sliding connection around its perimeter; an elastic pressing assembly 93 is installed at the lower part of the lifting end of the pressing power component 92, and a pressing seat 94 is installed at the lower part of the pressing power component 92 and in the middle of the elastic pressing assembly 93, as shown in the attached figure. Figure 10 As shown, the lifting seat is connected to the elastic pressing assembly and the pressing seat. The pressing seat 94 contains an elastic sleeve 95 for contacting the pressure sensor. The elastic pressing assembly 93 includes a connecting plate 931 connected to the pressing power component 92, as shown in the attached diagram. Figure 11 As shown, straight rods 932 are installed around the lower perimeter of the connecting plate 931; a sliding sleeve 933 is fitted onto the straight rod 932, and a straight plate 934 that abuts against the valve seat is installed on the sliding sleeve 933. A stabilizing spring 935 is provided between the sliding sleeve 933 and the connecting plate 931; during the descent of the entire mechanism, the straight plate will first contact the edge of the valve seat to stabilize it. As the pressing power component continues to operate, the elastic sleeve will be fitted onto the pressure sensor, thereby pressing the pressure sensor into the valve seat. A limiting component is installed on the side of the pressing seat. During the downward movement of the pressing seat, the limiting component can prevent the pressing seat from moving too far downward, thus affecting the pressing effect. The elastic component 95 includes a positioning sleeve 951 disposed in the pressing seat 94, as shown in the attached figure. Figure 12As shown, an end plate 952 for fixing a positioning sleeve 951 is installed at the lower port of the press-fit base 94. An elastic element 953 is installed inside the positioning sleeve 951. The elastic element mainly consists of a rod and a spring. A pressure sleeve 954 for pressing a pressure sensor is installed at the lower end of the elastic element 953. The pressure sleeve will first contact the pressure sensor. During the pressing process, the spring will be compressed, thus achieving flexible pressing of the pressure sensor. After the complete pressure sensor is pressed, a pressure holding process is required. Gas pressure holding is used. An air nozzle 955 is installed on the side of the elastic element. Pressure holding gas is introduced into the pressure sleeve through the air nozzle and presses the pressure sensor.

[0034] The pressure sensor feeding mechanism 5 includes a lifting main frame 51 located at one end of the workbench 1, as shown in the attached figure. Figure 2 As shown, the lifting main frame 51 is equipped with a vertically arranged discharge slide 52 and a feed fixed slide 53, as shown in the attached diagram. Figure 3 and 4 As shown, the feeding fixed slide is mainly composed of a bracket and track plates. The track plates on both sides can support material trays. A feeding thrust assembly 54 is installed on the lifting main frame 51 at the bottom of the outer end of the feeding fixed slide 53. A positioning assembly 55 for positioning the material tray is installed above the inner end of the discharging movable slide 52. A discharging thrust assembly 56 is installed on the lifting main frame 51 at the bottom of the discharging movable slide 52. A lifting assembly 57 for moving the material tray from the feeding fixed slide 53 to the positioning assembly 55 is installed at one end of the lifting main frame 51 at the inner end of the feeding fixed slide 53. A material tray equipped with multiple pressure sensors is positioned at the outer end of a fixed feeding chute. A feeding thrust assembly moves the material tray to the inner end of the fixed feeding chute. A lifting assembly then elevates the material tray into a positioning assembly, effectively positioning it for material gripping. An empty material tray is then lowered onto a movable discharge chute via the lifting assembly. The discharge thrust assembly moves the empty material tray toward the outer end of the movable discharge chute. This invention, by arranging the feeding and discharging processes in upper and lower layers, provides ample material handling space and a rational spatial layout, thus improving work efficiency.

[0035] The discharge chute 52 includes track fixing blocks 521 symmetrically arranged on the upper part of the lifting main frame 51, and a fixing track component 522 is installed on the inner side of the track fixing block 521; a first unidirectional flipping track component 523 corresponding to the end of the fixing track component 522 is installed on the upper part of the lifting main frame 51, as shown in the attached figure. Figure 5As shown, the discharge thrust assembly 56 is located below the fixed track component 522 and the first one-way flipping track component 523; the upper end of the track fixing block 521 is equipped with the second one-way flipping track component 524; the upper part of the lifting main frame 51 and located below the fixed track component 522 is equipped with a lifting discharge cylinder 525. The first one-way flipping track component 523 mainly includes a fixing plate 231, a fixing block 232 is provided on the fixing plate 231, a movable block 233 is hinged to one side of the fixing block 232, and a track piece 234 is connected to one side of the movable block 233. The track piece can be flipped in one direction from bottom to top. When the lifting component sends the material tray into the positioning component, it will pass through the first one-way flipping track component, so that the track pieces on both sides flip upward. After the material tray passes, the track piece will automatically reset. During the process of the lifting seat moving the empty material tray down, the material tray can be placed on the track piece. The structure of the second one-way flipping track component is the same as that of the first one-way flipping track component. When the lifting assembly lifts the material tray, it pushes open the first one-way tilting track component, after which the material tray moves into the positioning assembly. The positioning assembly 55 includes two top plates mounted on the main frame and located above the first one-way tilting track component. The grooves on the top plates 51 together form a limiting groove. Multiple limiting plates for positioning the material tray are installed at the opening of the limiting groove. The lifting seat sends the material tray into the limiting groove, and the edge of the material tray touches the limiting plates. When the empty material tray is discharged, the moving end of the lifting assembly moves the empty material tray down, and the empty material tray is placed in the first one-way tilting track component. The empty material tray is fed onto the flipping track component, and then the discharge thrust component sends the empty material tray to the fixed track component. Then, the lifting discharge cylinder moves the empty material tray upward, opening the second one-way flipping track component. After that, the empty material tray is moved downward and placed on the second one-way flipping track component, and then the empty tray can be taken out. There is a certain height difference between the discharge height of the fixed track component and the actual height that the worker can reach. The worker may need to bend over to pick up the empty tray. The second one-way flipping track component is mainly set up to facilitate the work of taking out the empty material tray.

[0036] The lifting assembly 57 includes a frame plate 571 disposed at one end of the lifting main frame 51. A lifting rodless cylinder 572 is installed on the inner side of the frame plate 571. A lifting seat 573, which moves between the positioning assembly 55 and the feeding fixed slide 53, is connected to the inner side of the frame plate 571 via a slider assembly. The moving end of the lifting rodless cylinder 572 is connected to the lifting seat 573. A limiting corner guard rail 574 corresponding to the positioning assembly 55 is installed on the inner side of the frame plate 571. To ensure that the material tray can accurately enter the limiting groove, the tray can rise along the limiting corner guard rail when the lifting seat drives the tray to rise.

[0037] The material tray is placed on the slide in a frame-like manner, and is therefore moved on the slide by a cylinder. The feeding thrust assembly includes a rodless cylinder, the moving end of which is connected to a clamping block. A long rod is mounted on the clamping block, and piston cylinders are installed at both ends of the long rod. The extended ends of the piston cylinders are connected to top columns. During feeding, the piston cylinders on both sides extend, and the rodless cylinder moves, causing the top columns to extend, moving the tray on the fixed feeding slide. When it approaches the lifting seat, the top column connected to the extended end of the piston cylinder at one end of the long rod retracts, and the rodless cylinder continues to move. Continuing operation, the piston cylinder at the other end of the long rod continues to drive the tray to move. The retracted piston cylinder moves below the lifting seat, and the top column on the extended piston cylinder engages with the arc groove at the end of the lifting seat, at which point the rodless cylinder stops. Then the lifting seat moves upward, thus removing the material tray. The structure of the discharge thrust assembly is similar to that of the feed thrust assembly, except for the structure of the moving end. The long rod at the moving end is equipped with a piston cylinder on only one side. The rodless cylinder moves to the inner end of the discharge sliding track, and the top column at the extended end of the piston cylinder extends. The rodless cylinder operates, and the top column drives the empty tray to move outward.

[0038] The sensor detection mechanism 6 includes a detection main frame 61 mounted on the workbench 1, as shown in the attached figure. Figure 6 As shown, a horizontal moving assembly 62 is installed on the main frame 61 being tested. A vertical cylinder 63 is installed on the moving end of the horizontal moving assembly 62. A feeding cylinder 64 is installed on the extended end of the vertical cylinder 63. A rotary cylinder 65 is connected to the extended end of the feeding cylinder 64. A semi-circular rotating seat 66 is provided on the rotating end of the rotary cylinder 65. The horizontal moving assembly, the feeding cylinder, and the rotary cylinder are used in combination to facilitate the feeding and discharging of the pressure sensor. A suction assembly 67 for absorbing the pressure sensor is installed at the end of the semi-circular rotating seat 66. The pressure sensor is absorbed by negative pressure. Compared with the gripping method of a robotic arm, this method can effectively avoid deformation caused by gripping and provides better protection for the pressure sensor. A testing table 68 is installed on the worktable 1, as shown in the attached figure. Figure 9As shown, the detection platform 68 is equipped with a material rotating assembly 69 for rotating the pressure sensor. The material rotating assembly 69 includes an active motor 691 mounted on the detection platform 68. The extended end of the active motor 691 is connected to an active pulley 692. The detection platform 68 is equipped with a fixed frustum 693. The fixed frustum 693 is equipped with a rotatable material platform 694. A driven pulley 695 is mounted on the outer side of the material platform 694. A belt 696 is wound around the active pulley 692 and the driven pulley 695. Since it is necessary to achieve dynamic detection of the pressure sensor port, the rotation of the material platform is achieved through belt drive. The pressure sensor is mounted inside the material platform. The side of the testing table 68 is provided with a test piece placement rack 70. The pneumatic gripper of the robotic arm has a negative pressure suction assembly on its side, which mainly delivers the pressure sensor from the pressure sensor feeding mechanism to the test piece placement rack. The testing table is surrounded by a light source 71, a first sensor 72, and a second sensor 73. Since the second sensor is located on the side of the testing table, after the pressure sensor completes the inspection of one end face, the semi-circular rotating seat drives the pressure sensor to rotate, and the other end face of the pressure sensor corresponds to the second sensor to achieve end face detection. The light source is mainly used to improve the brightness of the testing environment. The first sensor mainly detects the flatness of one end of the pressure sensor and whether there are any gaps or damages. The other end of the pressure sensor is mainly a metal head that connects to other electrical components. The second sensor is used to check whether the metal head is damaged or bent. In this embodiment, the first and second sensors are photoelectric sensors, using the Sick W2S series. This is a high-performance photoelectric sensor with extremely high accuracy and sensitivity, suitable for object detection in automated equipment. The housing of this type of sensor is also relatively robust, and the sensor is not affected by chemical, thermal, or mechanical environments.

[0039] The suction assembly 67 includes a fixing plate 671 disposed on the semi-circular rotating seat 66, as shown in the attached figure. Figure 7 As shown, a positioning seat 672 is installed at the inner end of the semi-circular rotating seat 66, and a straight tube 673 is installed inside the positioning seat 672, as shown in the attached diagram. Figure 8 As shown, the upper end of the straight pipe 673 is connected to a gas delivery hose 674. One end of the gas delivery hose 674 passes through a rotary cylinder 65 and is connected to a negative pressure source. The lower end of the straight pipe 673 is provided with a stabilizing block 675. The lower end of the straight pipe is used to attach a pressure sensor.

[0040] The working principle of this invention is as follows: A conveyor belt transports a transfer fixture containing a valve seat to a robotic arm. The robotic arm clamps the valve seat onto a material platform. A sliding feeding assembly delivers the material platform to below the pressing main frame. A pressure sensor feeding mechanism moves a material tray containing a pressure sensor to the feeding position. The robotic arm moves the pressure sensor to a sensor detection mechanism, where both ends of the pressure sensor undergo quality inspection. After inspection, the pressure sensor is then transferred back to the material platform via a removal component within the sensor detection mechanism. Through the combined operation of multiple mechanisms, the valve seat is lifted during pressure sensor installation. The automation level is increased, reducing the intensity of manual labor. During the press-fitting of the pressure sensor, the press-fitting power component is activated and drives the elastic pressing assembly and the press-fitting seat to move downward. The elastic pressing assembly first contacts the valve seat of the solenoid valve, and the press-fitting power component continues to drive the press-fitting seat to move downward. The flexible pressing top is fitted onto the pressure sensor. During press-fitting, the flexible pressing top will retract upward, and the pressure sensor is stably installed on the valve body of the solenoid valve. The pressure sensor is press-fitted in a flexible manner, reducing the surface deformation of the pressure sensor surface, improving the adaptability of the pressure sensor when it is inserted into the valve body, and ensuring installation accuracy.
