Description

Technical Field

[0001] This utility model relates to the field of automation equipment, specifically an automatic copper tube assembly device. Background Technology

[0002] Currently, some connecting pipe structures include metal iron caps and copper pipes. When assembling these connecting pipes, the copper pipes need to be manually inserted into the openings on the side wall of the iron caps for pre-fixation. Then, the assembled connecting pipes are manually placed onto a stamping machine. Finally, one end of the copper pipe is completely stamped into the iron cap. Finally, a welding ring is placed on the outside of the copper pipe, so that the welding ring is close to the joint between the copper pipe and the iron cap, for subsequent welding and fixing.

[0003] The entire process, from placing, inserting, fitting, and collecting the parts, is done manually. This not only results in low production efficiency and high costs, but also easily leads to fatigue and injury due to manual operation. Therefore, further improvement is necessary.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 9As shown, an automatic copper tube assembly device includes a support base plate 1. The support base plate 1 is provided with an assembly station X for fixing an iron cover. The support base plate 1 is provided with a feeding station, a correction station, a detection station and a stamping station on the periphery of the assembly station X. The feeding station is provided with an iron cover feeding mechanism 91 for conveying the iron cover to the assembly station X and a copper tube transfer mechanism 92 for transferring the copper tube to the upper side of the iron cover. The correction station is provided with an iron cover correction mechanism 93 for fixing the iron cover and controlling the axial rotation of the iron cover. The detection station is provided with an opening positioning mechanism 94 for detecting the position of the opening on the upper side wall of the iron cover. The stamping station is provided with a copper tube stamping mechanism 95 for inserting the copper tube into the opening.

[0030] This automatic copper tube assembly equipment can fully automate the feeding, inspection, position correction, copper tube stamping and unloading processes in the assembly process. No manual intervention is required throughout the entire process. This not only effectively reduces labor costs and avoids problems such as fatigue and injury during manual operation, but also ensures that the entire assembly process is carried out in a continuous manner with short intervals, resulting in high production efficiency.

[0031] The iron cover correction mechanism 93 includes a rotary motor 931 and a correction motion device that controls the rotary motor 931 to move back and forth relative to the assembly station X. A chuck 932 is fixedly connected to the output end of the rotary motor 931. Two or more iron cover jaws 933 that move relative to each other are connected to the chuck 932. The iron cover jaws 933 perform outward support movement to clamp the iron cover.

[0032] The correction motion device includes a correction base plate 934 fixed on the support base plate 1. A second transverse guide rail 935, a correction slider 936 slidably connected to the second transverse guide rail 935, and a transverse correction cylinder 937 are connected to the correction base plate 934. The rotary motor 931 is fixed on the correction slider 936, and the piston shaft of the transverse correction cylinder 937 is connected to the rotary motor 931 for transmission.

[0033] In this embodiment, the chuck 932 is connected to two opposing iron cover claws 933. The iron cover claws 933 are semi-circular arc-shaped. When the iron cover claws 933 are outwardly supported to clamp the iron cover, they can better fit the inner wall of the iron cover and prevent the iron cover claws 933 from scratching the iron cover.

[0034] The opening positioning mechanism 94 includes a needle seat 941, an opening positioning needle 942 elastically connected to the needle seat 941, and a needle seat movement device for controlling the movement of the needle seat 941. The needle seat 941 is provided with a position sensing element 943, and the opening positioning needle 942 is fixed with a trigger part 9411 that cooperates with the position sensing element 943. When the opening positioning needle 942 is inserted into the opening of the iron cover, the trigger part 9411 activates the trigger signal of the position sensing element 943.

[0035] Among them, the needle base moving device includes a needle base bracket 944. A needle base transverse movement cylinder 945 is fixedly connected to the needle base bracket 944. A needle base lifting cylinder 946 is drivingly connected to the piston shaft of the needle base transverse movement cylinder 945. A needle base connecting plate 947 is fixed on the piston shaft of the needle base lifting cylinder 946. The needle base 941 is fixed on the needle base connecting plate 947.

[0036] And in this embodiment, the needle base 941 has a "C" - shaped structure. Through - holes suitable for the up - and - down sliding of the hole - opening positioning needle 942 are provided on its upper and lower wall parts. The position sensing element 943 is arranged on the side wall part of the needle base 941. The triggering part 9411 is limited to slide between the upper and lower wall parts. A reset spring 948 is sleeved on the upper part of the hole - opening positioning needle 942. The reset spring 948 abuts between the upper wall part and the triggering part 9411, so that the hole - opening positioning needle 942 can achieve elastic sliding.

[0037] The copper tube transplanting mechanism 92 includes a transplanting bracket 921 fixed on the carrying bottom plate 1. The transplanting bracket 921 is connected with a first transverse guide rail 922, a transplanting slider 923, and a transverse transplanting cylinder 924 for driving the transplanting slider 923 to slide along the first transverse guide rail 922. A lifting transplanting cylinder 925 is fixed on the transplanting slider 923, and a copper tube clamp 926 is drivingly connected to the piston shaft of the lifting transplanting cylinder 925.

[0038] The copper tube stamping mechanism 95 includes a stamping bracket 951. An installation platform 952 is arranged on the upper side of the assembly station X on the stamping bracket 951. A stamping cylinder 953 is fixed on the installation platform 952. The piston shaft of the stamping cylinder 953 extends downward towards the assembly station X and is fixedly connected with an up - and - down moving stamping needle 954.

[0039] A iron cover tooling seat 96 is fixedly connected to the carrying bottom plate 1. An arc - shaped groove is opened on the top surface of the iron cover tooling seat 96. The arc - shaped groove constitutes the assembly station X. One side of the arc - shaped groove is higher and the other side is lower. An iron cover in - place sensor 961 is arranged on the higher side X1. The iron cover feeding mechanism 91 includes an iron cover vibrating disc 911. The iron cover discharge channel 912 of the iron cover vibrating disc 911 is docked with the lower side X2 of the arc - shaped groove.

[0040] When the iron cover on the iron cover vibrating disc 911 rolls into the arc - shaped groove from the lower side X2, the higher side X1 can also play a role in limiting the iron cover, preventing the iron cover from rolling out of the assembly station X due to inertia.

[0041] The stamping cylinder 953 is provided with a piston shaft sensor 955 that is linked to the copper tube transfer mechanism 92 at the middle position. The piston shaft sensor 955 cooperates with the piston shaft of the stamping cylinder 953. When the piston shaft of the stamping cylinder 953 extends to the position where the stamping needle 954 just presses against the top of the copper tube, the piston shaft sensor 955 is triggered. The piston shaft sensor 955 controls the copper tube clamp 926 to release the copper tube. This structure prevents the copper tube clamp 926 from scratching the outer wall surface of the copper tube when the stamping needle 954 further presses the copper tube.

[0042] An iron cover limiting plate 97 is fixedly installed on the rear side of the assembly station X. The iron cover limiting plate 97 is provided with a jet nozzle 971 that blows towards the assembly station X. An outwardly inclined discharge slide 98 is fixedly installed on the front side of the assembly station X. After the iron cover and copper tube are assembled, the jet nozzle 971 blows high-pressure gas towards the iron cover, blowing the iron cover and copper tube out of the assembly station X and causing them to fall into the discharge slide 98, thus completing the workpiece unloading.

[0043] Based on the above structure, the working principle of the automatic copper tube assembly equipment is as follows:

[0044] Iron covers A roll one by one from the iron cover vibrating plate 911 along the iron cover discharge channel 912 into the assembly station X. At this time, iron covers A are placed sideways and their openings face the iron cover correction mechanism 93.

[0045] The rotary motor 931 is driven by the correction motion device to move forward to the assembly station X position, and then the chuck 932 controls the iron cover jaws 933 to clamp the iron cover A.

[0046] The needle holder 941 is driven by the needle holder moving device to move to the upper side of the iron cover A. Initially, the opening positioning needle 942 elastically presses against the side wall of the iron cover A. (Refer to...) Figure 5 As shown, the trigger part 9411 cooperates with the position sensing element 943 (indicating that the opening A1 of the iron cover A has not reached the designated position).

[0047] Then, the rotary motor 931 operates and drives the iron cover A to rotate axially for correction. When the opening A1 of the iron cover A rotates to face directly upward, the opening positioning pin 942 is inserted into the opening A1 under the potential energy of the return spring 948. (Refer to...) Figure 6 As shown, the trigger part 9411 moves downward and is offset from the position sensing element 943. At this time, the position sensing element 943 sends a signal to control the rotary motor 931 to stop working. Then the hole positioning pin 942 leaves the iron cover A and moves out of the assembly station X.

[0048] Reference Figure 8 and Figure 10As shown in the left figure, the copper tube clamp 926 holds the copper tube B and moves it to the upper side of the opening A1. Then, the stamping cylinder 953 drives the stamping needle 954 to move downward. When the stamping needle 954 presses against the top surface of the copper tube B, the trigger piston shaft of the stamping cylinder 953 triggers the piston shaft sensor 955, thereby controlling the copper tube clamp 926 to release. Afterward, the stamping needle 954 moves further downward until the copper tube B is pressed into the iron cover A. (Refer to...) Figure 10 As shown in the right figure.

[0049] The jet nozzle 971 blows high-pressure gas toward the iron cover B, blowing the combined structure of the iron cover A and copper tube B out of the assembly station X and into the discharge slide 98, thus completing the workpiece unloading.
