[0023] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0024] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides a condenser cleaning device, including a spray cleaning chamber 1, a conveying unit 4 for moving the condenser and a spray assembly 3 for cleaning the condenser are installed inside the spray cleaning chamber 1, a plurality of clamps for clamping the condenser are evenly installed outside the conveying unit 4, the clamp includes a plurality of groups of clamps 16 for clamping the condenser installed on the top, and a top pressure sensor 17 for detecting the clamping force is embedded and fixedly installed inside the clamp 16;

[0025] A positioning plate 8 for adjusting the clamping position of the condenser is installed below the clamp 16, and a bottom pressure sensor 9 for detecting the clamping force is embedded and fixedly installed on the inner side of the positioning plate 8. An adjusting plate 13 for squeezing and adjusting the position of the condenser is symmetrically installed on the inner side of the positioning plate 8, and a linkage mechanism is installed between the adjusting plate 13 and the positioning plate 8. Specifically, a warning light 2 is fixedly installed on the top of the spray cleaning chamber 1, and the warning light 2 is electrically connected to the bottom pressure sensor 9 and the top pressure sensor 17.

[0026] In this embodiment, Figure 2As shown, the adjustment plate 13 centers the condenser in the longitudinal direction, and the positioning plate 8 clamps the condenser to center it in the transverse direction. In addition, the height of the positioning plate 8 is fixed, so that the three-dimensional position of the condenser is basically fixed, and the clamping claws 16 clamp the condenser.

[0027] Specifically, a mounting frame 6 is fixedly installed on the top of the conveying unit 4, and a bottom electric push rod 7 and a top electric push rod 18 are fixedly installed in the middle of the mounting frame 6. The telescopic end of the top electric push rod 18 is fixedly connected to the clamp 16, and the top electric push rod 18 is used to drive the clamp 16 to clamp the condenser tube. The telescopic end of the bottom electric push rod 7 is fixedly connected to the positioning plate 8, and the bottom electric push rod 7 is used to drive the positioning plate 8 to clamp the condenser tube.

[0028] In this embodiment, the telescopic end of the top electric push rod 18 extends, driving the clamping jaws 16 to clamp the condenser. If the pressure values ​​of the two top pressure sensors 17 meet the standard, it meets the set requirements, otherwise the warning light 2 flashes. Positioning is performed first and then clamping, so that the clamping jaws 16 and the condenser are accurately matched and the clamping is stable, reducing the possibility of the clamping jaws 16 damaging the condenser due to offset clamping.

[0029] Specifically, the linkage mechanism includes a large return spring 12, a receiving groove is opened at the end of the positioning plate 8, the large return spring 12 is fixedly installed inside the receiving groove, and an extrusion plate 10 is fixedly installed at the end of the large return spring 12. The large return spring 12 is used to drive the extrusion plate 10 to reset, and the extrusion plate 10 is slidably installed inside the receiving groove;

[0030] A slope 11 is provided on the outside of the extrusion plate 10, and a limit rod 15 is slidably installed on the outside of the slope 11. The end of the limit rod 15 away from the extrusion plate 10 is fixedly connected to the adjustment plate 13, and a small return spring 14 is fixedly installed between the adjustment plate 13 and the positioning plate 8 for driving the adjustment plate 13 and the limit rod 15 to reset. The small return spring 14 is movably installed on the periphery of the limit rod 15.

[0031] In this embodiment, the telescopic end of the bottom electric push rod 7 is extended, driving the positioning plates 8 to approach each other, and the squeezing plates 10 are not in contact. The staff places the condenser on the positioning plate 8, and the telescopic end of the bottom electric push rod 7 continues to extend, and the squeezing plates 10 begin to contact and squeeze each other. The squeezing plates 10 partially enter the storage groove, and the large return spring 12 is compressed. With the help of the slope 11, the limit rod 15 and the adjustment plate 13 are driven to move and squeeze the condenser. The small return spring 14 is stretched to make the condenser centered in the longitudinal direction (such as Figure 2 As shown in FIG. 1 ), the telescopic end of the bottom electric push rod 7 extends again, driving the positioning plate 8 to clamp the condenser tube so that it is centered in the horizontal direction (as shown in FIG. 1 ). Figure 2 As shown), the bottom pressure sensor 9 is used to detect the squeezing force. If the condenser position adjustment meets the set standard, the values ​​detected by the two bottom pressure sensors 9 are up to standard. If not, the warning light 2 flashes to remind the staff.

[0032] Specifically, a control computer 5 is fixedly installed on the outside of the spray cleaning chamber 1 to facilitate the staff to check the working status and adjust the operation rhythm of each unit.

[0033] How it works:

[0034] The telescopic end of the bottom electric push rod 7 extends, driving the positioning plates 8 to approach each other, and the squeezing plates 10 do not touch each other. The staff places the condenser tube on the positioning plate 8, and the telescopic end of the bottom electric push rod 7 continues to extend, and the squeezing plates 10 begin to contact and squeeze each other. The squeezing plates 10 partially enter the storage groove, and the large reset spring 12 is compressed. With the help of the slope 11, the limit rod 15 and the adjustment plate 13 are driven to move and squeeze the condenser tube. The small reset spring 14 is stretched to make the condenser tube centered in the longitudinal direction (such as Figure 2 As shown in FIG. 1 ), the telescopic end of the bottom electric push rod 7 extends again, driving the positioning plate 8 to clamp the condenser tube so that it is centered in the horizontal direction (as shown in FIG. 1 ). Figure 2 As shown), the bottom pressure sensor 9 is used to detect the extrusion force. If the position adjustment of the condenser meets the set standard, the values ​​detected by the two bottom pressure sensors 9 are up to standard. If not, the warning light 2 flashes to remind the staff. During this process, the horizontal position of the extrusion plate 10 contacts the limit rod 15, and the limit rod 15 is no longer squeezed. The two-way positioning, coupled with the fixed height of the positioning plate 8, makes the three-dimensional position of the condenser basically fixed, which is convenient for subsequent precise clamping.

[0035] The telescopic end of the top electric push rod 18 extends, driving the clamping jaws 16 to clamp the condenser. If the pressure values ​​of the two top pressure sensors 17 meet the standard, it meets the set requirements, otherwise the warning light 2 flashes. Positioning is performed first and then clamping, so that the clamping jaws 16 and the condenser are accurately matched and the clamping is stable, reducing the possibility of the clamping jaws 16 damaging the condenser due to offset clamping.

[0036] The telescopic end of the bottom electric push rod 7 is shortened and reset, and the elasticity of the large reset spring 12 and the small reset spring 14 drives each component to reset, and the conveying unit 4 conveys the clamped condenser tube to the spray assembly 3 for cleaning.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
