Description

Technical Field

[0001] This utility model relates to the technical field of heat exchanger testing, and in particular to a closed-tube detector for D-type manifolds in automotive heat exchangers. Background Technology

[0002] With the continuous innovation of automotive radiators, the current radiator manifolds no longer use the conventional crimping seal between injection-molded parts and aluminum alloy parts (main board). Instead, a new process has been adopted, where the aluminum alloy manifolds and the core are integrated and brazed together. In the old process, after the B-type tubes were assembled with the main board, the operator could visually eliminate more than 90% of the tube clogging problems. However, the new process uses D-type manifolds to replace the main board and water chamber, making it impossible to visually observe the condition of the assembled core B-type tube openings. To reduce the product rejection rate, those skilled in the art need to design a device that can detect the clogging of the D-type manifolds before brazing. Utility Model Content

The clamping device 11 includes a first driving device 111, a connecting block 112, and a pressure block 113. The connecting block 112 is fixed to the drive shaft of the first driving device 111 by fasteners. The connecting block 112 and the pressure block 113 are fixed together. The first driving device 111 is configured to drive the connecting block 112 and the pressure block 113 to rotate and to drive the pressure block 113 to press or move away from the workpiece 8 to be tested.

[0043] Preferably, the work box 1 is equipped with a start button, a pause button, a touch screen 15, a display 16, an alarm, a host computer, and an electrical control cabinet 19. The start button and pause button are directly connected to the input module (such as the digital input terminal of a PLC) of the electrical control cabinet 19, transmitting switch signals via hard wiring. The touch screen 15 is connected to the controller (such as a PLC) inside the electrical control cabinet 19 via a communication line (such as RS232 or Ethernet), and also communicates with the host computer via a network. The display 16 is connected to the host computer via a VGA, HDMI, or USB cable, serving as the host computer's output device; in some scenarios, it may also be directly connected to the controller of the electrical control cabinet 19 to display the status of each port of the D-type manifold. The alarm is connected to the output module (such as the relay output terminal of a PLC) of the electrical control cabinet 19, and its start and stop are controlled by the controller. It alerts operators (e.g., equipment failure, parameter exceeding limits, process timeout) through audible and visual alarms (such as a buzzer and warning light). The host computer connects to the electrical control cabinet 19 via Ethernet or a dedicated communication protocol (such as Modbus or OPC) to achieve data interaction and remote control. The electrical control cabinet 19, as the core control unit, integrates all input and output signals and serves as the "central connection point" for all components.

[0044] Preferably, the fixing plate 9 is provided with a support slot 20, the support slot 20 is L-shaped, the short side of the L-shape is fixedly connected to the fixing plate 9, and the long side of the L-shape is provided with a slot, the width of the slot is the same as the width of the first connecting plate 91, the slot is configured to restrict the first connecting plate 91 within the slot 201 to prevent its movement.

[0045] like Figure 12 As shown, a support frame 20 is provided below the fixed plate 9 to support the fixed plate 9. A crossbeam is provided inside the work box 1. The fixed plate 9 is placed at an angle on the crossbeam, dividing the work box behind the fixed plate 9 into upper and lower spaces. The lower space is used to place the electrical control cabinet 19. The start button, pause button, touch screen 15, and display 16 are placed on the work box frame in front of the fixed plate 9. The alarm is set on the outer top surface of the work box 1.

[0046] The bottom of the work box 1 is equipped with casters 23 for easy movement of the entire unit. The work box has doors on the front, back, left, and right sides for easy inspection and maintenance of each component.

[0047] Workflow: First, power and air supply the detector. Then, turn on the host computer and monitoring software. If there is no alarm on the touch screen 15, click the automatic reset screen to start the operation. Place the workpiece 8 to be tested on the first support block 103 and the second support block 123, press the start button, and the equipment starts. Under the control of the PLC, the transverse servo module 2 drives the second servo module 4 and the fourth servo module 6 to move towards the workpiece to be tested, clamping the workpiece 8 and then stopping the movement. Then, under the control of the PLC, the clamping device 11 first drives... The first drive device 111 drives the connecting block 112 and the pressing block 113 to rotate, rotating the pressing block 113 to the opposite side of the workpiece 8 to be inspected. Then, the first drive device 111 drives the connecting block 112 and the pressing block 113 to press against the workpiece 8 to be inspected. Then, under the control of the PLC, the endoscope device 7, which is matched with the first servo module 3, the second servo module 4, the third servo module 5, and the fourth servo module 6, moves to the set opening of the workpiece 8 to be inspected under the action of its servo motor. The detection probe collects the image of the opening and transmits it through the endoscope. The device converts the raw electrical signal output by the detection probe into a USB standard data format, and then transmits it to the host computer via a USB cable. The monitoring software uses a high-precision image recognition algorithm to compare the acquired image with a standard pipe opening status diagram. If the comparison is successful (meets acceptance requirements), the acquired image displayed on the monitor will show a green indicator; if the comparison fails (does not meet acceptance requirements), the acquired image displayed on the monitor will show a red indicator. When the detection probe has acquired the image of the pipe opening, the endoscope device 7, which is matched with the first servo module 3, the second servo module 4, the third servo module 5, and the fourth servo module 6, moves to the next pipe opening of the workpiece 8 under the action of its servo motor to continue acquiring images and uploading them to the host computer for comparison, until all pipe openings have been photographed. The first servo module 3, the second servo module 4, the third servo module 5, and the fourth servo module 6 then return to their original positions. When the photoelectric switch in the original position senses the light-blocking plate, the clamping device 11 also returns to its original position. Finally, the transverse servo module 2 returns to its original position, the workpiece is removed, and the inspection is completed.

[0048] This invention uses multiple endoscope devices to simultaneously inspect the nozzles of the workpiece, thus accelerating the inspection process and improving work efficiency. In addition, after comparing the acquired images with standard nozzle status diagrams, the color is used to distinguish whether the comparison has passed, clearly indicating which nozzle does not meet the requirements.
