[0029] The assembling device further comprises an assembling mechanism, and the workbench 1 is arranged with a first electric sliding rail 15 extending along the width direction thereof, the assembling mechanism comprising a base 19 slidingly arranged along the first electric sliding rail 15, the base 19 being arranged with a mounting table 20 for placing the water-cooled plate, one side of the mounting table 20 being connected with a limiting mechanism for limiting the water-cooled plate, and the other side being arranged with a pressing mechanism; the workbench 1 is arranged with a third electric sliding rail 25 extending along the length direction thereof, the pressing mechanism comprising a top base 26 slidingly arranged along the third electric sliding rail 25, the top base 26 being arranged with a mounting plate 27 provided with a water nozzle mounting hole, the mounting plate 27 being arranged opposite to the mounting table 20 and being on the same horizontal plane; the limiting mechanism comprising a connecting plate 14 connected with the base 19, the connecting plate 14 being arranged with a second electric sliding rail 16, the second electric sliding rail 16 being slidingly arranged with a support base 17, the support base 17 being arranged with an L-shaped limiting block 18. Figure 1The water cooling plate is placed on the mounting table 20, and the left end is limited by the limiting block 18. After the water nozzle moves to the left, it can be pressed and installed at the end of the water cooling plate. Further, a high-precision pressure sensor can be provided on the mounting plate 27 to monitor the pressing force in real time. Not only can it prevent overpressure damage to the parts, but it can also ensure that the pressing is in place and ensure the consistency of the assembly gap, thereby providing good conditions for subsequent welding and significantly improving the reliability and consistency of the final product.

[0030] Further, the support seat 17 is provided with a fixing seat 28, the limiting block 18 is connected with the fixing seat 28, and the fixing seat 28 is provided with a first groove 30 extending along the width direction thereof.

The fourth electric sliding rail 11 is slidably provided with a support plate 12. The support plate 12 is provided with a scanner 13. By means of the foregoing technical features, one code corresponds to one water cooling plate, facilitating traceability work.

[0033] The working process is as follows: S1, manual feeding and preliminary positioning: the operator places the water cooling plate on the mounting table 20, specifically in the slot formed by the plurality of top blocks and the inner wall of the mounting table 20, at the same time the pressing block 23 of the pressing mechanism is lowered to contact the upper surface of the water cooling plate, then the base 19 is moved to drive the mounting table 20 to move to the detection area, and the code scanning and water cooling plate pipe mouth detection are performed; after the detection is passed, the welding wire and the plugging piece are taken out in turn and installed on the water cooling plate pipe mouth, and then the water nozzle is placed on the mounting plate 27.

[0034] S2, CCD vision online monitoring: the operator presses the button to control the CCD vision system to start, and then the assembled water cooling plate (welding wire, sealing sheet assembly) is moved to the detection area again for photographing, and the image processing unit analyzes the image (if the detection is passed, that is, there is no missing assembly, no misassembly, and the placement is in place, a green light signal is sent out, and the press-fitting system is triggered ready; if the detection is not passed, a red light and sound and light alarm signal are sent out, and the specific error type such as "missing sealing sheet" is displayed on the man-machine interface, prompting the operator to correct).

[0035] S3, press-fitting: after the detection of the above steps is passed, the base 19 is reset, and the pressing mechanism starts to work, specifically, the top base 26 moves to drive the mounting plate 27 to move to press the water nozzle to the pipe opening of the water cooling plate, and the pressure sensor feedbacks the pressure data in real time; if the pressure value is within the normal range, the mounting plate 27 is pressed to the position and then reset after keeping the pressure for a moment, and the assembly is completed; if the pressure is abnormal (such as exceeding the maximum upper limit, prompting "over-pressing"; or below the minimum lower limit, prompting "insufficient pressing"), the system immediately stops pressing and alarms, protecting the product from damage.

[0036] S4, assembly is completed, the top base 26 and the pressing block 23 are reset, and after manual visual inspection is qualified, it is transferred to the next station; by means of the assembly mode of the foregoing technical features, a semi-automatic mode of "manual feeding plus equipment pressing and detection" is adopted, which not only utilizes the flexibility and judgment of manual work to adapt to multi-variety production, but also ensures the pressing quality and precision through automatic equipment, and the overall cost is much lower than that of a fully automatic production line, and the flexibility is great.

[0037] The above is only a preferred embodiment of the present application, and any skilled person in the art can make any simple modification, equivalent change and modification to the above embodiment without departing from the technical solution of the present application, which still belongs to the scope of the technical solution of the present application.
