[0016] The wheel rim weld and air tightness detection equipment provided by the present invention has a reasonable and compact structure and layout. In particular, the lifting disc driven by the air tightness detection lifting cylinder presses the wheel rim workpiece into a flat state and fixes it on the upper part of the air tightness detection table, so that the inner cavity of the wheel rim workpiece forms a closed environment. After the inner cavity of the wheel rim workpiece in the closed environment is inflated (filled with an air pressure of about 1Mpa) through the inflation tube, the air tightness detection probe driven by the Z-direction air tightness detection driving motor and the Y-direction air tightness detection driving cylinder is displaced along the Y-direction and the Z-direction, so as to measure the air pressure in the non-weld area and the weld area of ​​the wheel rim workpiece respectively.

The two areas should be (one is the non-weld area, the other is the weld area), so the air tightness of the weld area is judged by the airflow pressure difference between the non-weld area and the weld area of ​​the rim workpiece. This structural design and detection method greatly improves the air tightness detection efficiency and detection accuracy, breaks the traditional domestic manual naked eye recognition method, changes the traditional contact air tightness detection, and greatly improves the rim air tightness detection level; at the same time, the operation and adjustment are also convenient, which greatly saves production costs, improves processing efficiency, and effectively guarantees the product quality of the rim workpiece, thereby improving the reliability and safety of tubeless cars.

[0018] In terms of space, the present invention saves space for workstation settings through integrated design and application, and each device is tightly arranged, making the equipment beautiful and reasonable. It changes the traditional manual loading and utilizes motor and cylinder drive to move the entire feeding system in the X, Y and Z directions, and truly move the rim from point to point. The supporting device is controlled by a servo motor, and the gear rack transmission and the screw transmission can control the movement position more accurately, and has a large load-bearing capacity and a long service life.

[0064] The working principle of the feeding device 1 is:

[0065] When the photoelectric switch of the feeding channel detects the rim workpiece on the feeding channel 12, the photoelectric switch of the feeding channel sends a signal to the PLC controller, and the PLC controller sends a signal to the feeding channel top material cylinder solenoid valve, thereby controlling the feeding channel top material cylinder 141 to load the material. When the rim workpiece rolls down the feeding channel 12 to the rim workpiece flipping bracket 131 on the upper part of the flipping rack 13, the photoelectric switch of the flipping rack detects it and sends a signal to the PLC controller, and the PLC controller sends a signal to the flipping cylinder solenoid valve, thereby controlling the flipping cylinder 15 to flip the rim workpiece 90 degrees. After the flipping is completed, it is detected by a pair of material tipping rack proximity switches, which send signals to the PLC controller, and the PLC controller sends a signal to the push cylinder solenoid valve, which controls the push cylinder 172 to push the rim workpiece to the specified position of the push channel 162. At this time, it is detected by the push channel photoelectric switch, and the push channel photoelectric switch sends a signal to the PLC controller, which sends a signal to the manipulator lifting cylinder solenoid valve and the gripper cylinder solenoid valve, which controls the manipulator lifting cylinder 27 and the gripper cylinder 262 to grab the rim workpiece through the gripper 264.

[0066] The weld detection principle of the weld detection device 3 is:

[0067] After the rim workpiece 6 is transported to the workpiece placement plate 34 through the supporting device 2, the photoelectric switch of the workpiece placement plate sends a signal to the PLC controller, and the PLC controller sends a signal to the motor servo drive module. The motor servo drive module controls the weld detection reduction motor 33 to drive the workpiece placement plate 34 to rotate through the rotating shaft 331, thereby driving the rim workpiece 6 to rotate. When the weld of the rim workpiece 6 turns to the detection position, since the weld detection camera 36 is electrically connected to the background computer, the weld detection camera 36 identifies the weld by identifying the weld image and sends a signal to the background computer. The background computer sends a signal to the PLC controller, and the PLC controller sends a signal to the motor servo drive module. The motor servo The servo drive module controls the weld detection servo motor 32 and the weld detection reduction motor 33 to stop, thereby stopping the workpiece placement plate 34; in the weld identification and positioning stage, the weld detection camera 36 is used to capture the specific image of the rim workpiece 6 driven by the weld detection servo motor 32 and the weld detection reduction motor 33 to rotate. After capturing the specific image of the weld, the weld detection camera 36 uses the rim rotation image to identify the weld. If a weld is detected, the signal is transmitted to the background computer, and the background computer sends a signal to the PLC controller, which sends a signal to the motor servo drive module, and the motor servo drive module controls the weld detection servo motor 32 to stop rotating, so as to accurately locate the weld.

[0068] The airtightness detection principle of the airtightness detection device 4 is:

[0069] After the weld of the rim workpiece 6 is detected by the weld detection device 3, it is grabbed by the gripper 264 of the supporting device 2 to the workpiece placement disc 42 of the airtightness detection table 41. The photoelectric switch of the workpiece placement disc detects the rim and sends a signal to the PLC controller. The PLC controller controls the solenoid valve of the airtightness detection ejection cylinder, and then the airtightness detection ejection cylinder 44 ejects the ejection disc 411, and fixes the rim workpiece 6 in a flat position on the workpiece placement disc 42 of the airtightness detection table 41. The upper and lower openings of the rim workpiece are respectively closed by the ejection disc 411 and the workpiece placement disc 42, so that the inner cavity of the rim workpiece 6 is in a closed environment, and it is filled with an air pressure of about 1Mpa, and the Z-axis airtightness detection drive motor 47 is driven. The Y-axis air tightness detection driving motor 48 drives the air tightness detection probe 49 to move along the Y-axis and the Z-axis, and is used to detect the air tightness at the weld of the rim workpiece 6. There are two air flow sensors at the weld of the rim workpiece 6 (one is the non-weld area, and the other is the weld area), which are transmitted to the air tightness detection probe 49, i.e., the gas flow sensor. When a certain air flow pressure difference value is reached, since the gas flow sensor is electrically connected to the air tightness detection control board, the gas flow sensor will transmit the signal to the air tightness detection control board, and the air tightness detection control board will send a signal to the PLC controller. The air tightness detection control board has a programmed program, and different signals will be transmitted when a certain pressure difference is reached; if the pressure difference value is reached, the air tightness detection control board will send a signal to the PLC controller and the electrical operating console, and finally the electrical operating console will display an alarm, thereby performing air tightness detection of the entire rim.
