[0002] At present, in the process of inserting long copper tubes of air conditioner outdoor units, most of them are inserted manually, and a small part uses a reverse guidance device for insertion. Manual insertion is labor-intensive, and the reverse guidance device has the disadvantages of large equipment footprint and high failure rate due to fin differences. Summary of the invention

[0003] The purpose of the present invention is to provide an air conditioner outdoor unit long copper tube insertion assembly process to solve the problems existing in the above-mentioned prior art, which can reduce the equipment footprint, reduce labor costs, improve work efficiency, and have high equipment operation stability.

[0004] To achieve the above object, the present invention provides the following solutions:

[0005] The present invention provides a long copper tube insertion assembly process for an air conditioner outdoor unit, comprising the following steps:

[0006] 1) Place the fins on the workbench manually and tidy them up, then press the start button with both hands;

[0007] 2) The electric cylinder moves the fin to the copper tube insertion station;

[0008] 3) The horizontal clamping mechanism shrinks the left and right spaces to straighten the fins, so that the fin holes are aligned with the guide needle position;

[0009] 4) After the fin hole is aligned with the guide needle tube hole, the tube insertion machine pushes the copper tube into the rear end of the guide needle first, and then inserts it into the fin together with the guide needle;

[0010] 5) The lateral clamping mechanism moves the fins with copper tubes to the next station, and then moves them to the unloading station through the lower transfer mechanism;

[0011] 6) The unloading and stacking mechanism lifts the fins with copper tubes and moves them to the elevator for stacking.

[0012] Preferably, the steps of inserting the guide pin into the guide groove are as follows:

[0013] 1) The needle storage plate and needle push plate with guide needles make the guide needles concentric with the guide grooves;

[0014] 2) After the guide pin is concentric with the guide groove, the rear push pin plate pushes the guide pin in the needle storage plate into the guide groove, and then it drops to avoid the position. After avoiding, the rear copper tube is pushed into the fin group along the guide pin. After the front end of the copper tube is pushed into the fin group, the upper and lower modules forming the guide groove are separated and avoided to ensure that the U-shaped tail end of the copper tube can be smoothly inserted into the position;

[0015] 3) Then the guide needle reflux device waits behind the fin for the guide needle to be in place, and the conveying mechanism moves to the other end to recycle the guide needle, which is then used for the next cycle.

[0016] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0017] The air conditioner outdoor unit long copper tube insertion assembly process provided by the present invention has a small equipment footprint in the entire process, reduces labor costs, improves work efficiency, and has high equipment operation stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the invention is to provide a long copper tube insertion assembly process for an air conditioner outdoor unit to solve the problems existing in the prior art.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-Figure 6 As shown, the long copper tube insertion assembly process of the air conditioner outdoor unit in this embodiment includes the following steps:

[0030] 1) If Figure 2 As shown, the fin 1 is manually placed on the workbench 2 and arranged, and then the two-hand start button is pressed;

[0031] 2) If Figure 3 As shown, the electric cylinder moves the fin 1 to the copper tube inserting station 3;

[0032] 3) If Figure 3 As shown, the transverse clamping mechanism 4 contracts the left and right spaces to straighten the fin 1, so that the hole of the fin 1 is aligned with the position of the guide needle 5;

[0033] 4) After the hole of fin 1 is aligned with the tube hole of guide needle 5, the tube insertion machine pushes the copper tube 6 into the rear end of guide needle 5 first, and then inserts it into fin 1 together with guide needle 5;

[0034] 5) The lateral clamping mechanism 4 moves the fin 1 with the copper tube 6 to the next station, and then transfers it to the unloading station through the lower transfer mechanism;

[0035] 6) The unloading and stacking mechanism lifts the fin 1 with the copper tube 6 inserted and moves it to the elevator for stacking.

[0036] In this specific embodiment, the steps of inserting the guide pin 5 into the guide groove 7 are as follows:

[0037] 1) If Figure 4 As shown, the needle storage plate 9 and the needle push plate 10 with the guide needle 5 are raised from the bottom end, so that the guide needle 5 is concentric with the guide groove 7;

[0038] 2) If Figure 5As shown, after the guide pin 5 is concentric with the guide groove 7, the rear push pin plate 10 pushes the guide pin 5 in the needle storage plate 9 into the guide groove 7, and after being pushed in, it drops to an avoidance position. After avoiding, the rear copper tube 6 is pushed into the fin group 1 along the guide pin 5. After the front end of the copper tube 6 is pushed into the fin group 1, the upper and lower modules of the guide groove 7 are formed (as shown in FIG. Figure 6 As shown) separate and avoid to ensure that the 6U-shaped tail end of the copper tube can be smoothly inserted into the position;

[0039] 3) Then the guide needle 5 reflux device waits behind the fin 1 for the guide needle 5 to be in place, and the conveying mechanism will descend and move from the bottom end of the platform to the other end to recover the guide needle 5, which will then be used for the next cycle.

[0040] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
