[0036] It also includes a left clamping plate 3, a right clamping plate 4 and an annular expansion airbag 5; the left portion of the base 1 is provided with a left clamping plate 3, and the right portion of the base 1 is provided with a right clamping plate 4; an annular expansion airbag 5 is fixedly connected to the opposite sides of the left clamping plate 3 and the right clamping plate 4; the two ends of the collecting pipe 100 to be assembled are clamped and fixed by the left clamping plate 3 and the right clamping plate 4, and the collecting pipe 100 to be assembled is expanded and fixed by the annular expansion airbag 5.

[0037] It also includes a first electric push rod 101, an annular guide rail 102, a first transverse moving platform 103 and a first drive motor 104; the left part of the base 1 is fixedly connected to the first electric push rod 101 through a bracket; the telescopic part of the first electric push rod 101 is fixedly connected to the annular guide rail 102, and the annular guide rail 102 is rotatably connected to the left clamping plate 3; the right side of the base 1 is fixedly connected to the first transverse moving platform 103, and the first drive motor 104 is installed on the moving part of the first transverse moving platform 103, and the rotating part of the first drive motor 104 is fixedly connected to the right clamping plate 4.

[0038] A visual camera is also included, and the position status of the flat tube insertion port 100a and the spacer insertion port 100b is determined by the visual camera.

[0039] It also includes a second drive motor 201, a first detection rod 202, a third drive motor 203 and a second detection rod 204; the second drive motor 201 is fixedly connected to the moving part of the first horizontal moving platform 103; the rotating part of the second drive motor 201 is fixedly connected to the first detection rod 202; the third drive motor 203 is on the moving part of the first horizontal moving platform 103, and the third drive motor 203 is located on the lower side of the second drive motor 201; the rotating part of the third drive motor 203 is fixedly connected to the second detection rod 204.

[0040] The first detection rod 202 and the second detection rod 204 are configured as cylindrical bodies, which are more convenient for embedding into the spacer insertion port 100b.

[0041] The placement seat 2 is provided with a receiving groove 2a for placing the header 100 to be assembled.

[0042] The present invention is proposed to solve the problem that during the installation of plugs and spacers on a condenser header, the plugs at both ends can be automatically assembled, while the assembly of the spacers still requires manual operation by staff, which is inefficient.

[0043] In the present invention, the plug of the header is assembled by subsequent automated equipment; the spacer is installed in the spacer insertion port 100b of the header 100 to be assembled;

[0044] When the present invention is in operation, the staff places the manifold 100 to be assembled in the receiving groove 2a of the placement seat 2, such as Figure 5 As shown, the moving part of the first transverse moving platform 103 is then controlled to drive the first driving motor 104, the right clamping plate 4, and the annular expansion airbag 5 to move leftward, the right clamping plate 4 contacts the header 100 to be assembled, and the annular expansion airbag 5 on the right clamping plate 4 is embedded in the inner right part of the header 100 to be assembled;

[0045] Then, the first electric push rod 101 is controlled to push the annular guide rail 102 and the left clamping plate 3 to move rightward, so that the left clamping plate 3 contacts the manifold 100 to be assembled, and the annular expansion airbag 5 on the left clamping plate 3 is embedded in the inner left part of the manifold 100 to be assembled, so that the limiting work of the manifold 100 to be assembled is realized by the left clamping plate 3 and the right clamping plate 4;

[0046] Then, the two annular expansion airbags 5 are controlled to expand, and the manifold 100 to be assembled is firmly fixed by the annular expansion airbags 5. Figure 3 As shown;

[0047] It should be noted that the flat tube insertion opening 100a and the spacer insertion opening 100b of the manifold 100 to be assembled are punched out, and have burrs 100ab as shown in the figure. Therefore, the present invention uses the annular expansion airbag 5 to expand and fix the manifold 100 to be assembled on both sides of the manifold 100 that are not punched, so as to overcome the problem of burrs 100ab.

[0048] Then control the first drive motor 104 to drive the right clamping plate 4 to rotate, and then drive the left clamping plate 3, the right clamping plate 4, the annular expansion airbag 5, and the collecting pipe 100 to be assembled to rotate slowly and synchronously, and at the same time, the left clamping plate 3 and the annular guide rail 102 rotate relative to each other; observe through the visual camera whether the flat tube insertion port 100a or the spacer insertion port 100b is in the forward position, to control whether the first drive motor 104 stops rotating.

[0049] Furthermore, since there is still a certain error in the visual camera observation, in order to eliminate the error, the present invention controls the second driving motor 201 to drive the first detection rod 202 to rotate when the septum insertion port 10b needs to be facing upward, and the first detection rod 202 is Figure 7 Slowly turn to Figure 8 In the horizontal state, the first detection rod 202 is judged whether it can be rotated 90 degrees to judge whether the spacer insertion port 10b is facing upward; similarly, when the flat tube insertion port 10a needs to face upward, the third driving motor 203 is controlled to drive the second detection rod 204 to rotate, and the second detection rod 204 is controlled to rotate 90 degrees. Figure 7 Slowly turn to Fig. 9 The horizontal state of the flat tube insertion opening 100a is determined by judging whether the second detection rod 204 can be rotated 90 degrees to judge whether it is facing upward;

[0050] As can be seen from the above, the present invention can realize automatic clamping and positioning of the manifold 100 to be assembled, and through the dual protection of the visual camera and the first detection rod 202 and the second detection rod 204, the flat tube insertion port 100a or the spacer insertion port 100b is automatically placed in an upward state, which is convenient for the staff to operate.

[0051] Example 2

[0052] On the basis of Example 1, Figure 1-15 As shown, it also includes a mounting frame 301, a second electric push rod 302, a connecting plate 303 and a detection head 304; two mounting frames 301 are fixedly connected on the base 1 and located behind the placement seat 2; the second electric push rod 302 is fixedly connected to the top of the mounting frame 301; the connecting plate 303 is fixedly connected to the telescopic part of the second electric push rod 302; the connecting plate 303 is fixedly connected to the detection heads 304 matching the number of the flat tube insertion openings 100a; by judging whether the detection heads 304 can be inserted into the flat tube insertion openings 100a, it is detected whether the flat tube insertion openings 100a can be successfully inserted into the flat tube insertion openings 100a later.

[0053] Each detection head 304 is rotatably connected to a push plate 304a on both sides, and the upper part of the push plate 304a is rotatably connected to the detection head 304; a rectangular expansion airbag 304b is set in the middle of each detection head 304, and the expansion of the rectangular expansion airbag 304b pushes the push plate 304a to rotate outward.

[0054] Due to the presence of burrs 100ab, some flat tubes may not be able to be inserted into the flat tube insertion openings 100a during the subsequent condenser assembly work, resulting in the need for rework, unnecessary damage and time waste. Therefore, the flat tube insertion openings 100a of the manifold 100 to be assembled can be controlled to face upward, and then the second electric push rod 302 can be controlled to drive the connecting plate 303 and the detection head 304 to move downward, so that the detection head 304 is inserted into the corresponding flat tube insertion opening 10a. If the detection head 304 is difficult to insert or cannot be inserted, it means that there is a problem with the manifold 100 to be assembled, and the staff needs to take it out for analysis.

[0055] Furthermore, after the detection head 304 can be inserted, the problem of burr 100ab still exists. The flat tube may be damaged when it is subsequently inserted. Based on this problem, after the detection head 304 is inserted, the rectangular expansion airbag 304b can be controlled to expand, and then the two push plates 304a can be pushed out to both sides. The burr 100ab shown in the figure can be squeezed to both sides through the rectangular expansion airbag 304b, so that the burr 100ab cannot contact the inserted flat tube subsequently.

[0056] It should be noted that if the detection head 304 is difficult or impossible to insert, a sensor can be provided to identify the force of the second electric push rod 302 to determine whether the insertion is difficult.

[0057] It can be seen from the above that the present invention realizes the insertion test detection of the flat tube insertion port 100a and the elimination treatment of the burr 100ab.

[0058] Example 3

[0059] On the basis of Example 1, Figure 1-15As shown, it also includes a second transverse moving platform 401, a third electric push rod 402, a connecting frame 403 and a suction cup 404; the second transverse moving platform 401 is fixedly connected to the middle part of the mounting frame 301; the third electric push rod 402 is fixedly connected to the moving part of the second transverse moving platform 401; the connecting frame 403 is fixedly connected to the telescopic part of the third electric push rod 402; the suction cup 404 is fixedly connected to the connecting frame 403; the spacers are provided to the suction cup 404 by manual or external spacer feeding equipment.

[0060] It also includes a fourth electric push rod 405, a downward pressing arc plate 406 and an electric telescopic plate 407; the fourth electric push rod 405 is fixedly connected to the connecting frame 403; the telescopic part of the fourth electric push rod 405 is fixedly connected to the downward pressing arc plate 406; the downward pressing arc plate 406 is located on the left side of the suction cup 404, and the suction cup 404 is set to the left; two electric telescopic plates 407 are installed on the lower side of the downward pressing arc plate 406, and the telescopic part of the electric telescopic plate 407 extends out to block the lower edge 200a of the spacer 200 to be inserted.

[0061] When the spacers are assembled automatically, the spacer insertion port 100b is rotated to face upward, and the spacers are added to the suction cup 404 by the staff or the spacer feeding device. Fig.14 , 15 As shown, the spacer is sucked by the suction cup 404, and then the moving part of the second horizontal moving platform 401 is controlled to drive the third electric push rod 402, the connecting frame 403, the suction cup 404, the fourth electric push rod 405, the downward pressing arc plate 406, the electric telescopic plate 407, and the spacer to move. When the spacer moves to the top of the spacer insertion port 100b, the third electric push rod 402 is controlled to drive the suction cup 404 and the spacer to move downward, so that the spacer is inserted into the spacer insertion port 100b. When the suction cup 404 is against the manifold 100 to be assembled, the third electric push rod 402 stops pushing, and the suction cup 404 stops sucking the spacer. At this time, the third electric push rod 402 is controlled to drive the suction cup 404 and the spacer to move downward, so that the spacer is inserted into the spacer insertion port 100b. The four electric push rods 405 push the arc plate 406 downward and move the spacer downward, so that the spacer is completely inserted into the spacer insertion port 100b; further, considering that the spacer 200 (spacer) to be inserted has a lower edge 200a, in order to ensure that the lower edge 200a fits accurately with the spacer insertion port 100b, the telescopic parts of the two electric telescopic plates 407 can be controlled to extend and press against the lower edge 200a. When the lower edge 200a is about to contact the spacer insertion port 100b, the telescopic parts of the two electric telescopic plates 407 are controlled to retract. In this way, the spacer can be prevented from deflecting during the insertion process, resulting in poor insertion effect and the need for reassembly and insertion.

[0062] As can be seen from the above, the present invention can achieve automatic insertion of the spacer into the spacer insertion port 100b, and at the same time can prevent the spacer from deflecting during the insertion process, resulting in poor insertion effect and the need for reassembly and insertion.

[0063] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
