[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] Since the notch of the manifold 2 is on the circumferential surface of the manifold 2, the conventional straight-pushing method of the flat tube 11 easily causes a corner of the flat tube 11 to abut against the notch first due to position angle deviation, so that the flat tube 11 is stuck and it is difficult to fit closely with the notch. Therefore, the utility model designs such a manifold 2 assembly mechanism, such as Figure 1 As shown, it includes a first piece 1, on which is provided a first groove 3 for horizontally placing the collecting tube 2, the length direction of the collecting tube 2 is defined as the first direction, the opening direction of the first groove 3 is the same as the direction of the notch of the collecting tube 2, the first piece 1 can move in the second direction and the third direction respectively, the second direction and the third direction are both perpendicular to the first direction, the second direction is defined as the horizontal direction, and the third direction is defined as the vertical direction, then when the flat tube 11 is partially inserted into the notch of the collecting tube 2, the first piece 1 moves horizontally in the second direction and vertically in the third direction at the same time, so that when the collecting tube 2 is assembled with the flat tube 11 and the fin, the collecting tube 2 has a tendency to rotate and push relative to the flat tube 11, compared with the existing direct push assembly, the assembly method corresponding to the assembly structure of the utility model can avoid the problem that a certain corner of the flat tube 11 first abuts against the notch due to the position angle deviation, so that the flat tube 11 is stuck and difficult to fit tightly with the notch.

[0025] Among them, the component that drives the first piece 1 to move in the second direction is a cylinder, or it can be a servo motor, etc., and the component that drives the first piece 1 to move in the third direction is a cylinder, or it can be a servo motor, etc., and the corresponding matching sliding rails. The utility model requires two sets of manifold 2 assembly mechanisms for the assembly of a complete condenser core. The two sets of manifold 2 assembly mechanisms are relatively arranged, and the assembly of the flat tube 11 and the manifold 2 is completed by synchronous action.

[0026] Embodiment 1:

[0027] like Figure 2 As shown, the first groove 3 is open on one side, the opening of the first groove 3 and the notch of the manifold 2 are in the same direction, the manifold 2 is inserted into the first groove 3 from the side of the first piece 1, the notch of the first groove 3 is provided with a second portion 10 for limiting the manifold 2, the notch of the first groove 3 is provided with a second portion 10 for limiting the manifold 2 from falling out of the opening of the first groove 3, the second portion 10 can be a slope or an arc-shaped slope, the first groove 3 and the manifold 2 are rotationally matched, the manifold 2 can rotate in the first groove 3, and when the manifold 2 is inserted into the first groove 3, the notch of the manifold 2 is inclined That is, the notch of the manifold 2 is not completely aligned with the opening of the first slot 3 at this time. When the head end of the flat tube 11 is horizontally inserted into the first slot 3 to the notch of the manifold 2, at this time, the first piece 1 realizes both horizontal and vertical movement under the drive of the two groups of power parts. Since the flat tube 11 has partially extended into the notch of the manifold 2 at this time, and the manifold 2 can rotate in the first slot 3, the movement of the first piece 1 can make the manifold 2 have a tendency to rotate and push, so that the flat tube 11 can completely and smoothly enter the notch when the manifold 2 rotates and pushes.

[0028] like Figure 1 As shown, the first member 1 is provided with a plurality of second grooves 4 connected with the first groove 3 at one end facing the flat tube 11, and the second grooves 4 are arranged side by side in the first direction, and a first portion 5 is formed between two adjacent second grooves 4, that is, the second groove 4 is a vertically arranged groove, and also includes a second member 6, and the second member 6 can move in a third direction (vertical direction) so that the second member 6 passes through the second groove 4 and enters the first groove 3, and the power unit driving the second member 6 to move in the third direction is a cylinder or a servo motor, etc., because the manifold 2 is prone to deviation when placed in the first groove 3, a corresponding sensor is provided, and the sensor can determine whether the notch of the manifold 2 is facing the correct direction, and in order to ensure the accuracy of the assembly of the flat tube 11, the third member 7 is driven by the power unit to move upward and extend into the second groove 4, and continue to extend upward until it is inserted into the notch of the manifold 2. At this time, the output positioning is accurate, that is, the placement position of the manifold 2 is accurate, and the subsequent assembly of the flat tube 11 can be carried out.

[0029] When the second slot 4 is set, the flat tube 11 and the fin are moved to the bottom of the second slot 4, the flat tube 11 is aligned with the second slot 4, the fin is aligned with the second part 10, and the flat tube 11 and the fin are moved upward, and the flat tube 11 enters the second slot 4 upward until it is partially inserted into the slot of the collecting tube 2, and the fin is against the second part 10. Since the collecting tube 2 is placed with the slot inclined, compared with the method of directly inserting the head end of the flat tube 11 into the slot, the insertion method of the utility model is more stable and safer.

[0030] The third piece 7 is fixed on the second piece 6. The third piece 7 and the second piece 6 can be arranged integrally. The second piece 6 and the third piece 7 can be two positioning plates. The two positioning plates are arranged in an "L" shape. When the second piece 6 enters the second groove 4, the third piece 7 is tightly attached to the first part 5. The purpose is also to ensure accurate positioning.

[0031] Embodiment 2:

[0032] like Figure 3 As shown, the first groove 3 is open on the upper side and one side, and the opening degree is relatively large.

In order to improve the stability of pressing, the fourth piece 8 is at least two groups, pressing the two ends of the collecting pipe 2 respectively. The power source driving the fourth piece 8 to move can also be a cylinder or a servo motor. Since the collecting pipe 2 is placed horizontally, in order to facilitate the stability of pressing of the fourth piece 8, the contact end of the fourth piece 8 and the collecting pipe 2 has a third groove 9 that cooperates with the outer peripheral surface of the collecting pipe 2. Preferably, the third groove 9 is a U-shaped groove.

[0033] The assembly principle is as follows: when the head section of the flat tube 11 enters the notch of the collecting pipe 2, the head end of the flat tube 11 rests against the top of the notch. At this time, the first piece 1 moves downward under the action of the power unit, and the collecting pipe 2 is separated from the first groove 3 under the action of the flat tube 11, and the bottom of the collecting pipe 2 is suspended. At this time, the fourth piece 8 above presses the collecting pipe 2 downward, and the collecting pipe 2 will rotate, that is, the fourth piece 8 presses the collecting pipe 2 straight, and the flat tube 11 can completely enter the notch of the collecting pipe 2.

[0034] like Figure 1As shown, the first member 1 is provided with a plurality of second grooves 4 connected with the first groove 3 at one end facing the flat tube 11, and the second grooves 4 are arranged side by side in the first direction, and a first portion 5 is formed between two adjacent second grooves 4, that is, the second groove 4 is a vertically arranged groove, and also includes a second member 6, and the second member 6 can move in a third direction (vertical direction) so that the second member 6 passes through the second groove 4 and enters the first groove 3, and the power unit driving the second member 6 to move in the third direction is a cylinder or a servo motor, etc., because the manifold 2 is prone to deviation when placed in the first groove 3, a corresponding sensor is provided, and the sensor can determine whether the notch of the manifold 2 is facing the correct direction, and in order to ensure the accuracy of the assembly of the flat tube 11, the third member 7 is driven by the power unit to move upward and extend into the second groove 4, and continue to extend upward until it is inserted into the notch of the manifold 2. At this time, the output positioning is accurate, that is, the placement position of the manifold 2 is accurate, and the subsequent assembly of the flat tube 11 can be carried out.

[0035] When the second slot 4 is set, the flat tube 11 and the fin are moved to the bottom of the second slot 4, the flat tube 11 is aligned with the second slot 4, the fin is aligned with the second part 10, and the flat tube 11 and the fin are moved upward, and the flat tube 11 enters the second slot 4 upward until it is partially inserted into the slot of the collecting tube 2, and the fin is against the second part 10. Since the collecting tube 2 is placed with the slot inclined, compared with the method of directly inserting the head end of the flat tube 11 into the slot, the insertion method of the utility model is more stable and safer.

[0036] The third piece 7 is fixed on the second piece 6. The third piece 7 and the second piece 6 can be arranged integrally. The second piece 6 and the third piece 7 can be two positioning plates. The two positioning plates are arranged in an "L" shape. When the second piece 6 enters the second groove 4, the third piece 7 is tightly attached to the first part 5.
