Description

Technical Field

[0001] The present invention relates to the field of air spring controller assembly equipment, and particularly to an electromagnetic valve pressing equipment for an air suspension system. Background Art

[0002] An air suspension system uses an air spring as an elastic element and utilizes the compressibility of gas to achieve its elastic effect. The air pressure of the compressed gas can be automatically adjusted according to the load and road conditions. In the whole system, the controller is a very important electrical component. The controller contains an electromagnetic valve. When assembling the electromagnetic valve, a pressure sensor needs to be installed on the valve seat.

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

[0015] 1. In the present invention, the conveyor belt carries the transfer tooling rack with the valve seat to the mechanical arm, the mechanical arm clamps the valve seat to the material table, the sliding feed assembly sends the material table to the bottom of the press-fitting main frame, the pressure sensor feeding mechanism moves the material tray with the pressure sensor to the feeding position, the mechanical arm moves the pressure sensor to the sensor detection mechanism, and performs quality inspection on both ends of the pressure sensor. After the inspection, the pressure sensor is sent to the material table through the removal piece in the sensor detection mechanism; through the combined operation of multiple mechanisms, the valve seat is lifted when the pressure sensor is installed. The degree of automation is improved, and the intensity of manual labor is reduced; when the pressure sensor is press-fitted, the press-fitting power part is started and drives the elastic pressing component and the press-fitting seat to move downward.

[0016] 2. In the feeding mechanism of the pressure sensor, feeding is achieved through the fixed feeding slide on the lower layer, 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 moved out from the discharging movable slide. The feeding and discharging are arranged in upper and lower layers, so that there is sufficient space for taking materials and the space layout is reasonable, which helps to improve work efficiency.

[0017] 3. In the sensor detection mechanism, the suction component mainly absorbs the pressure sensor through negative pressure.

Detailed implementation manners

[0031] The present invention will be further described below in conjunction with the attached drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0032] Embodiment: An electromagnetic valve press-fitting device for an air suspension system, including a workbench 1, as shown in the attachedFigure 1 As shown in the figure, a conveyor belt 2 is installed at one end of the workbench 1, and a transfer tooling rack 3 for placing valve seats is installed on the conveyor belt 2. After the transfer tooling rack reaches the feeding position, the lifting mechanism will lift the transfer tooling rack, and the transfer tooling rack will be separated from the conveyor belt; a robotic arm 4 for material movement is installed in the middle part of the workbench 1. The movable end of the robotic arm has a pneumatic gripper, and the pneumatic gripper can pick up the valve seat of the solenoid valve to achieve feeding. A pressure sensor feeding mechanism 5 is installed at the other end of the workbench 1; a sensor detection mechanism 6 and a press-fitting mechanism 7 are also installed on the workbench 1. The sensor detection mechanism 6, the press-fitting mechanism 7, and the pressure sensor feeding mechanism 5 are arranged around the robotic arm 4;

[0033] A sliding feeding assembly 8 is arranged below the press-fitting mechanism 7, and a material table 9 for placing valve seats is installed on the movable end of the sliding feeding assembly 8; the press-fitting mechanism 7 includes a press-fitting main frame 91 arranged on the workbench 1. A press-fitting power component 92 is installed on the press-fitting main frame 91. The press-fitting power component is mainly composed of a screw rod and a sliding sleeve. By driving the screw rod to rotate with a motor, the lifting of the sliding sleeve is realized, and the seat body connected to the sliding sleeve realizes lifting. At the same time, the periphery of the seat body is connected to the press-fitting main frame in a sliding connection form; a resilient pressing assembly 93 is installed below the lifting end of the press-fitting power component 92. A press-fitting seat 94 is installed below the press-fitting power component 92 and in the middle of the resilient pressing assembly 93, as shown in the appendix Figure 10 As shown in the figure, the lifting seat is connected to the resilient pressing assembly and the press-fitting seat. A resilient kit 95 for abutting against the pressure sensor is installed in the press-fitting seat 94; the resilient pressing assembly 93 includes a connecting plate 931 connected to the press-fitting power component 92, as shown in the appendix Figure 11 As shown in the figure, straight rods 932 are installed around the lower part of the connecting plate 931; a sliding sleeve 933 is sleeved on the straight rod 932, and a straight plate 934 abutting against the valve seat is installed on the sliding sleeve 933. A stabilizing spring 935 is arranged between the sliding sleeve 933 and the connecting plate 931; during the downward movement of the entire mechanism, the straight plate will first contact the edge of the valve seat to stabilize the valve seat. As the press-fitting power component continues to operate, the resilient kit will be sleeved on the pressure sensor, thereby pressing the pressure sensor into the valve seat. A limiting member is installed on the side of the press-fitting seat. During the downward movement of the press-fitting seat, the limiting member can prevent the downward movement stroke of the press-fitting seat from being excessive, thereby affecting the press-fitting effect. The resilient kit 95 includes a positioning sleeve 951 arranged in the press-fitting seat 94, as shown in the appendix Figure 12As shown in the figure, an end plate 952 for fixing the positioning sleeve 951 is installed at the lower port of the press-fitting seat 94. An elastic member 953 is installed inside the positioning sleeve 951. The elastic member is mainly composed of a rod body and a spring. A pressing sleeve 954 for press-fitting the pressure sensor is installed at the lower end of the elastic member 953. The pressing sleeve will contact the pressure sensor first. During the press-fitting process, the spring will be compressed, thus realizing the flexible press-fitting of the pressure sensor. After the complete press-fitting of the pressure sensor, pressure holding treatment is required. Gas pressure holding is adopted. A gas nozzle 955 is installed on the side of the elastic member. The pressure holding gas is introduced into the pressing sleeve through the gas nozzle, and the pressure sensor is pressed.

[0034] The pressure sensor feeding mechanism 5 includes a lifting main frame 51 arranged at one end of the workbench 1. As shown in the appendix Figure 2 As shown, an upper and lower arranged discharging movable slideway 52 and a feeding fixed slideway 53 are installed inside the lifting main frame 51. As shown in the appendix Figure 3 and 4 As shown, the feeding fixed slideway is mainly composed of a bracket and track pieces. The material trays can be erected on the two side track pieces. A feeding thrust assembly 54 is installed at the outer end bottom of the lifting main frame 51 and located at the feeding fixed slideway 53; a positioning assembly 55 for positioning the material tray is installed above the inner end of the discharging movable slideway 52, and a discharging thrust assembly 56 is installed at the bottom of the lifting main frame 51 and located at the discharging movable slideway 52; a lifting assembly 57 for moving the material tray from the feeding fixed slideway 53 to the positioning assembly 55 is installed at one end of the lifting main frame 51 and located at the inner end of the feeding fixed slideway 53. The material tray with multiple pressure sensors is at the outer end of the feeding fixed slideway. The feeding thrust assembly sends the material tray to the inner end of the feeding fixed slideway. Immediately afterwards, the lifting assembly lifts the material tray into the positioning assembly. The material tray is effectively positioned, and the grasping of the material can be realized. The empty material tray is lowered to the discharging movable slideway again through the lifting assembly, and the discharging thrust assembly drives the empty material tray to move towards the outer end of the discharging movable slideway; by arranging the feeding and discharging in upper and lower layers, the present invention has sufficient material taking space and reasonable space layout, which helps to improve the working efficiency.

[0035] The discharging movable slideway 52 includes symmetrically arranged track fixing blocks 521 on the upper part of the lifting main frame 51. A fixed track member 522 is installed inside the track fixing block 521; a first one-way flipping track member 523 corresponding to the end of the fixed track member 522 is installed on the upper part of the lifting main frame 51. As shown in the appendix Figure 5As shown in the figure, the discharging thrust assembly 56 is arranged below the fixed track member 522 and the first one-way flipping track member 523; the upper end of the track fixing block 521 is provided with a second one-way flipping track member 524; an elevating discharging air cylinder 525 is installed above the upper part of the elevating main frame 51 and below the fixed track member 522. The first one-way flipping track member 523 mainly includes a fixing plate 231, on which a fixing block 232 is provided. One side of the fixing block 232 is hinged with a movable block 233, and one side of the movable block 233 is connected with a track plate 234, which can realize the one-way flipping of the track plate from bottom to top. When the elevating assembly sends the material tray into the positioning assembly, it will pass through the first one-way flipping track member, so that the track plates on both sides will flip upward. After the material tray passes through, the track plates will automatically reset. When the elevating seat moves the empty material tray downward, the material tray can be erected on the track plates. The structure of the second one-way flipping track member is the same as that of the first one-way flipping track member. When the elevating assembly lifts the material tray, it will push open the first one-way flipping track member, and then the material tray will reach the positioning assembly. The positioning assembly 55 includes two top plates arranged on the main frame and above the first one-way flipping track member. The grooves on the top plate 51 together form a limiting groove, and a plurality of limiting plates for positioning the material tray are installed at the notch of the limiting groove. The elevating seat sends the material tray into the limiting groove, and the edge of the material tray touches the limiting plates. When discharging the empty material tray, the movable end of the elevating assembly will move the empty material tray downward. The empty material tray is placed on the first one-way flipping track member, and then the empty material tray is sent to the fixed track member through the discharging thrust assembly. Then, the empty material tray is lifted by the elevating discharging air cylinder, pushing open the second one-way flipping track member, and then the empty material tray is moved downward, and the empty material tray is erected on the second one-way flipping track member. Then, the empty tray can be taken out. There is a certain height difference between the discharging height of the fixed track member and the height at which the actual worker takes it. The worker may need to bend down to take the empty tray. The second one-way flipping track member is mainly set to facilitate the worker to take the empty material tray.

[0036] The elevating assembly 57 includes a frame plate 571 arranged at one end of the elevating main frame 51. An elevating rodless air cylinder 572 is installed inside the frame plate 571. The inside of the frame plate 571 is connected with an elevating seat 573 that moves between the positioning assembly 55 and the feeding fixed slideway 53 through a slider assembly. The movable end of the elevating rodless air cylinder 572 is connected with the elevating seat 573; a limiting corner track 574 corresponding to the positioning assembly 55 is installed inside the frame plate 571. To ensure that the material tray can accurately enter the limiting groove, when the elevating seat drives the tray to rise, the tray can rise along the limiting corner track.

[0037] The material tray is placed on the slideway in a mounted form. Therefore, a cylinder is used to drive the material tray to move on the slideway. The feeding thrust assembly includes a rodless cylinder. The moving end of the rodless cylinder is connected to a clamping block. A long rod is installed on the clamping block. Piston cylinders are arranged at both ends of the long rod. The extending end of the piston cylinder is connected to a jack. During feeding, the piston cylinders on both sides extend, and the rodless cylinder operates to drive the jacks to extend, driving the tray to move on the feeding fixed slideway. When approaching the lifting seat, the jack connected to the extending end of the piston cylinder at one end of the long rod retracts, and the rodless cylinder continues to operate. The piston cylinder at the other end of the long rod continues to drive the tray to move. The retracted piston cylinder moves under the lifting seat, and the jack on the extending piston cylinder is stuck into the arc groove at the end of the lifting seat, and the rodless cylinder can stop. Then the lifting seat moves upward, taking the material tray away. The structure of the discharging thrust assembly is similar to that of the feeding thrust assembly, except for the structure of the moving end. The long rod of the moving end is only provided with a piston cylinder on one side. The rodless cylinder moves to the inner end of the discharging movable slideway, and the jack at the extending end of the piston cylinder extends. The rodless cylinder operates, and the jack drives the empty tray to move outward.

[0038] The sensor detection mechanism 6 includes a detection main frame 61 arranged on the workbench 1. As shown in the appendix Figure 6 As shown, a lateral movement assembly 62 is installed on the detection main frame 61. A vertical cylinder 63 is installed on the moving end of the lateral movement assembly 62. A material discharging cylinder 64 is installed on the extending end of the vertical cylinder 63. A rotary cylinder 65 is connected to the extending end of the material discharging cylinder 64. A semi-circular rotary seat 66 is provided at the rotating end of the rotary cylinder 65. The combined use of the lateral movement assembly, the material discharging cylinder, and the rotary cylinder facilitates the feeding and discharging of the pressure sensor. A material suction assembly 67 for sucking the pressure sensor is installed at the end of the semi-circular rotary seat 66. The suction of the pressure sensor is achieved in a negative pressure form. Compared with the form of clamping by a manipulator, this form can effectively avoid the deformation caused by clamping and play a better protective role for the pressure sensor. A detection table 68 is installed on the workbench 1. As shown in the appendix Figure 9As shown in the figure, a material rotating assembly 69 for rotating the pressure sensor is provided inside the detection table 68. The material rotating assembly 69 includes a driving motor 691 arranged on the detection table 68. The protruding end of the driving motor 691 is connected with a driving pulley 692. A fixed circular table 693 is arranged on the detection table 68. A rotatable material table 694 is arranged on the fixed circular table 693. A driven pulley 695 is arranged on the outer side of the material table 694. A belt 696 is wound around the driving pulley 692 and the driven pulley 695. Since the ports of the pressure sensor need to be detected in a dynamic form, the rotation of the material table is realized through a belt drive form, and a pressure sensor is installed inside the material table. A placement rack 70 for the component to be measured is arranged on the side of the detection table 68. A negative pressure material suction assembly is arranged on the side of the pneumatic gripper of the robotic arm, which mainly realizes sending the pressure sensor in the pressure sensor feeding mechanism to the placement rack for the component to be measured. Light sources 71, a first sensor 72 and a second sensor 73 are arranged around the detection table. Since the second sensor is arranged beside the detection table, after one end face of the pressure sensor is inspected, 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 realize end face detection. The light source is mainly used to improve the brightness of the detection environment. The first sensor mainly detects the flatness of one end port of the pressure sensor, whether there are gaps or damages. The other end of the pressure sensor is mainly a metal head connected to other electrical components. The second sensor is used to detect whether there are defects on the metal head and whether the metal head is bent. In this embodiment, the first sensor and the second sensor are photoelectric sensors, adopting the W2S series of Sick. This is a high-performance photoelectric sensor with extremely high precision and sensitivity, suitable for object detection in automated equipment, and the housing of this type of sensor is also relatively firm, and the sensor is not affected by chemical, thermal and mechanical environments.

[0039] The material suction assembly 67 includes a fixed clamping plate 671 arranged on the semi-circular rotating seat 66, as shown in the appendix Figure 7 As shown in the figure, a positioning seat 672 is installed at the inner end of the semi-circular rotating seat 66. A straight pipe 673 is installed inside the positioning seat 672, as shown in the appendix Figure 8 As shown in the figure, the upper end of the straight pipe 673 is connected with an air conveying hose 674. One end of the air conveying hose 674 passes through the rotating cylinder 65 and is connected with a negative pressure source. A stabilizing block 675 is arranged at the lower end of the straight pipe 673. The lower end of the straight pipe is used for sleeving the pressure sensor.

[0040] The working principle of the present invention is as follows: the conveyor belt carries the transfer tooling frame with the valve seat to the mechanical arm, the mechanical arm clamps the valve seat to the material table, the sliding feed assembly sends the material table to the bottom of the press-fitting main frame, the pressure sensor feeding mechanism moves the material tray with the pressure sensor to the feeding position, the mechanical arm moves the pressure sensor to the sensor detection mechanism, and performs quality inspection on both ends of the pressure sensor. After the inspection, the pressure sensor is sent to the material table through the removal piece in the sensor detection mechanism; through the combined operation of multiple mechanisms, the valve seat is lifted when the pressure sensor is installed. The degree of automation is improved, and the intensity of manual labor is reduced; when the pressure sensor is press-fitted, the press-fitting power part is started and drives the elastic pressing component and the press-fitting seat to move downward. The elastic pressing component first conflicts with the valve seat of the solenoid valve, and the press-fitting power part continues to drive the press-fitting seat to move downward. The flexible pressing top part is sleeved on the pressure sensor. During press-fitting, the flexible pressing top part 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, which reduces the surface deformation of the pressure sensor surface, improves the adaptability of the pressure sensor when it is inserted into the valve body, and ensures the installation accuracy.
