Detailed Description

The following description of the technical solutions in the embodiments of the present utility model will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 17, in a first embodiment of the present utility model, an automatic tube penetrating device for heat exchange fins includes a table 70, a copper tube matrix 10 placed on the table 70, and a comb device 40 for performing tube penetrating operation of fins 52 for the copper tube matrix 10, wherein the table 70 is used for moving the copper tube matrix 10 to the lower side of an external fin punching device 50, so that the punched fins 52 directly drop onto copper tubes of the copper tube matrix 10; the carding device 40 carries out carding on the fins 52 on the copper pipe, so that the fins 52 are carded downwards and stacked on each other, thereby completing the operation of quickly sleeving the fins 52 on the copper pipe matrix 10; the comb device 40 is provided with a comb mechanism 41 and a power mechanism 60, the comb mechanism 41 is fixedly connected to the driving end of the power mechanism 60, the comb mechanism 41 is provided with a plurality of comb teeth 42, the comb teeth 42 are inserted into the copper pipe matrix 10 under the driving of the power mechanism 60, and the fins 52 are combed, so that the fins 52 move to a preset position.

In particular, because the air conditioner heat dissipation fins 52 are very thin, how to quickly and perfectly sleeve the fins 52 on the copper tube is a great difficulty in the current production. The holes on the fins 52 are very small in clearance relative to the copper tubes, and certain thrust is required to be applied to the copper tubes or the fins 52 in the tube penetrating process so as to facilitate tube penetrating operation. The conventional tube threading process requires collecting the fins 52 from the die cutting stage of the fin die cutting apparatus 50, and then moving the fins to a dedicated tube threading stage for tube threading operation, resulting in complicated tube threading process and low tube threading efficiency.

Secondly, the copper tube matrix 10 may also be mounted on a prefabricated work table 70, and then the copper tube matrix 10 is placed under the fin punching apparatus 50 by using the movement of the work table 70, so that the punched fins 52 directly fall onto the copper tube, and the tube penetrating operation is completed. This is quick but prevents subsequent fins 52 from falling due to friction between the fins 52 and the copper tubing. And the falling postures of the fins 52 are different, gaps between the fins and the copper pipe are not uniform, so that friction force after the fins 52 are stacked is exponentially increased after the fins 52 are increased, the fins 52 are difficult to fall to the bottom of the copper pipe, and pipe penetrating operation is completed.

Therefore, the intervention is needed in the falling process of the fins 52, and the comb device 40 is arranged to comb the fins 52, so that the fins 52 can be quickly and smoothly penetrated into the copper pipe. The comb device 40 can be arranged according to the specifications of the copper pipe matrix 10 and the fins 52 to be produced, a plurality of pieces of comb teeth 42 are fixed on the comb teeth seat 46, then the comb teeth mechanism 41 is combined, and the comb teeth mechanism 41 is fixed on the driving end of the power mechanism 60, so that the power mechanism 60 drives the fins 52 to carry out carding operation. The comb device 40 is further provided with a comb seat 46, and a plurality of comb teeth 42 are fixedly connected to the comb seat 46, thereby forming a comb mechanism 41.

It will be appreciated that the power mechanism 60 may be assembled by using various power devices in the prior art, for example, a mechanical arm may be used to assemble the power mechanism 60, for example, a sliding rail 31, a sliding block and a motor may be used to assemble the power mechanism 60. The mounting position of the comb device 40 can also be adjusted according to the power mechanism 60, for example, when a mechanical arm is used as the power mechanism 60, the degree of freedom is relatively large, so that the comb device does not occupy too much space. When the combination of the slide rail 31, the slide block and the motor is used as the power mechanism 60, the installation position thereof can be adjusted in combination with the movement mode of the workbench 70. When the table 70 uses a rotary table rotation movement, the slide rails 31 may be installed at both sides of the fin cutting apparatus 50 so as not to block the rotation of the table 70, and the comb mechanism 41 may be inserted from both sides of the copper tube matrix 10. When the table 70 is moved back and forth from side to side, the slide rail 31 may be mounted on the front side of the fin punching apparatus 50 so as not to block the movement of the table 70, and so as to insert the comb mechanism 41 on the front side of the copper tube matrix 10.

In addition, for convenience of description and understanding, when the fins 52 are dropped onto the copper tube matrix 10, as shown in fig. 8, corresponding names may be set according to the positions of the fins 52 on the copper tubes. Such as setting the position of the fin 52 on the tip of the guide pin 12 to the first position 14; setting the position lower than the first position 14 and at the uppermost end of the copper pipe as a second position 15; a position which is lower than the second position 15 and moves a certain distance to the bottom of the copper pipe is set as a third position 16; the position of the copper tube bottom or the stacking position where the fins 52 have been stacked together and gradually moved toward the copper tube bottom is set as the fourth position 17. The fin 52 may be combed by the card assembly 40 from the first position 14 directly to the fourth position 17, from the first position 14 to the second position 15, then from the second position 15 to the third position 16, and finally to the fourth position 17.

In a second embodiment, as shown in fig. 1 and 2, the comb device 40 is preferably provided with a first comb device 43, the first comb device 43 being arranged at the side of the copper tube matrix 10, so that the comb teeth mechanism 41 is inserted into the copper tube matrix 10 from the side and combs the fins 52 on the copper tubes. At least one group of comb devices 40 can be respectively arranged on two sides of the copper pipe matrix 10, wherein comb tooth mechanisms 41 on two sides penetrate into the copper pipe matrix 10 from two sides under the drive of a power mechanism 60, and fins 52 sleeved on the upper ends of the copper pipes are combed downwards, so that the fins 52 move downwards to a preset position.

Specifically, as shown in fig. 10 and 12, the distance between two adjacent copper tubes is very small from the side of the copper tube matrix 10, so that the comb teeth 42 inserted into the copper tube matrix 10 from the side need to be very thin to be smoothly inserted into the copper tube matrix 10. Also, since the copper tube matrix 10 has a relatively wide width from side to side, if the comb teeth 42 passing through the entire copper tube matrix 10 from the side are directly used, the length of the comb teeth 42 may be very long. While the front end of one long thin comb 42 is easy to shake, so that the fin 52 cannot be combed well because of instability. Therefore, the comb device 40 arranged at the side of the copper tube matrix 10 is preferably provided with one comb device 40 at each side, and after the comb teeth 42 of the comb device 40 at each side are respectively inserted into the copper tube matrix 10 from each side, the length of the comb teeth is better to comb all fins 52 on the whole copper tube matrix 10. While the second embodiment provides the comb device 40 on both sides of the copper tube matrix 10 and simultaneously inserts the comb device into the copper tube matrix 10 from both sides to comb the fins 52.

Secondly, the comb device 40 on both sides can be provided with a plurality of groups of comb devices 40 which can be operated independently, for example, a first comb device 43 is provided for moving the comb from the first position 14 to the second position 15, a third comb device 44 is provided for moving the comb from the second position 15 to the third position 16, and a second comb device 45 is provided for moving the comb from the third position 16 to the fourth position 17, so that the whole operation process of quickly sleeving the copper tube with the fins 52 is completed.

In a third embodiment, as shown in fig. 3, the comb device 40 is preferably provided with a second comb device 45, the second comb device 45 being arranged on the front side of the copper tube matrix 10 with respect to the external fin punching device 50, so that the comb teeth mechanism 41 is inserted into the copper tube matrix 10 from the front side and combs the fins 52 on the copper tube. At least one group of comb device 40 can be arranged on the front surface of the copper pipe matrix 10, wherein the front surface comb tooth mechanism 41 penetrates into the copper pipe matrix 10 from the front surface under the drive of the power mechanism 60, and fins 52 sleeved on the upper ends of the copper pipes are combed downwards, so that the fins 52 move downwards to a preset position.

Specifically, as shown in fig. 11 and 12, the distance between two adjacent copper tubes is relatively large from the front of the copper tube matrix 10, so that the comb teeth 42 inserted into the copper tube matrix 10 from the front can be relatively thick, and the length of the comb teeth 42 penetrating from the front is not required to be very long because the thickness of the copper tube matrix 10 is relatively narrow, so that the length of the comb teeth 42 penetrating from the front is relatively short and the thickness is relatively large, so that the comb blade device 40 is not required to be arranged at the front and the rear of the copper tube matrix 10, and only the comb blade device 40 is required to be arranged at the front side of the comb teeth 42 to penetrate into the copper tube matrix 10 from the front, and the fins 52 are combed.

Further, as in the second embodiment, the front comb device 40 may be provided with a plurality of sets of fins 52 that operate independently, so that the fins 52 are combed and penetrated in stages, which will not be described here.

In the fourth embodiment, as shown in fig. 6 and 7, it is preferable that the first comb device 43 is disposed at two sides of the copper tube matrix 10, the second comb device 45 is disposed at the front of the copper tube matrix 10, the comb teeth mechanism 41 of the first comb device 43 penetrates into the copper tube matrix 10 from two sides under the driving of the power mechanism 60, and the fins 52 sleeved at the first position 14 at the upper end of the copper tube are combed downwards to move downwards to the second position 15; the comb teeth mechanism 41 of the second comb device 45 penetrates into the copper pipe matrix 10 from the front under the drive of the power mechanism 60, and the fins 52 sleeved on the second position 15 are combed downwards so as to move downwards to the fourth position 17.

Specifically, since the uppermost end of the copper tube is provided with the guide pin 12, the diameter of the guide pin 12 is gradually reduced upward, thereby forming an upward tip. At the tip, the distance between two adjacent guide pins 12 is larger than the distance between the copper tubes, so that the first comb device 43 can be arranged on the side surface of the copper tube matrix 10, the first comb device 43 only needs to comb the comb from the first position 14 to the second position 15, and the comb teeth 42 of the first comb device 43 do not need to penetrate into a relatively narrow gap between the copper tubes, so that the thickness of the comb teeth 42 on the first comb device 43 can be set relatively larger, the stability of the comb teeth 42 is improved, and the carding efficiency is further improved. A second comb device 45 may also be provided on the front side to continue the comb at the second location 15 to comb down, thereby completing the entire carding process.

In the fifth embodiment, as shown in fig. 8, it is preferable that a first comb device 43 and a third comb device 44 are disposed on two sides of the copper tube matrix 10, a second comb device 45 is disposed on the front surface of the copper tube matrix 10, and the comb teeth mechanism 41 of the first comb device 43 penetrates into the copper tube matrix 10 from two sides under the drive of the power mechanism 60, and the fins 52 sleeved at the first position 14 on the upper end of the copper tube are combed downwards to move downwards to the second position 15; the comb tooth mechanism 41 of the third comb device 44 penetrates into the copper pipe matrix 10 from two sides under the drive of the power mechanism 60, and the fins 52 of the second position 15 are combed downwards so as to move downwards to the third position 16; the comb teeth mechanism 41 of the second comb device 45 penetrates into the copper pipe matrix 10 from the front under the drive of the power mechanism 60, and the fins 52 sleeved on the third position 16 are combed downwards so as to move downwards to the fourth position 17.

Specifically, this embodiment adds a third location 16 and a third comb device 44 as compared to the fourth embodiment. In the fourth embodiment, after the first carding unit 43 has carded the fins 52 from the first position 14 to the second position 15, it can be retracted to the home position, wait for the fins 52 to fall down to the first position 14, and form a stack of a certain number of fins 52 at the first position 14. Meanwhile, the second carding device 45 can comb the fins 52 of the second position 15 downwards, but in the process of combing downwards, the upper end of the copper pipe is loose, and the fins 52 fall onto the guide needle 12 from above, so that a certain impact force is formed on the guide needle 12 and is conducted to the copper pipe, the upper end of the copper pipe can shake slightly, the gap between the copper pipe and the fins 52 is changed, friction force is easily increased, resistance is increased in the process of combing the fins 52 on the second position 15 by the second carding device 45, and even the fins 52 are possibly blocked.

Therefore, in the fifth embodiment, by adding the third position 16 and the third carding unit 44, an auxiliary positioning structure composed of the fins 52 can be formed above the copper tube, so as to avoid the upper end of the copper tube from shaking, reduce friction force, and make the second carding unit 45 smoother in the process of carding the fins 52. When the second carding unit 45 combs the fins 52 located in the third position 16 downwards, the third carding unit 44 combs the fins 52 from the second position 15 to the third position 16, so that a group of fins 52 can be always maintained at the upper end of the copper tube in the copper tube matrix 10 to form an auxiliary locating structure, thereby stabilizing the upper end of the copper tube and avoiding the copper tube from shaking.

As shown in fig. 2, preferably, the power mechanism 60 is provided with a traversing rail 61, a traversing slide 62, a vertically moving rail 63, a vertically moving slide 64 and a power motor 65, the traversing rail 61 is fixedly connected to the workbench 70, the traversing slide 62 is movably connected to the traversing rail 61, the vertically moving rail 63 is fixedly connected to the traversing slide 62, the vertically moving slide 64 is movably connected to the vertically moving rail 63, and the comb mechanism 41 is fixedly connected to the vertically moving slide 64.

As shown in fig. 13, the copper tube matrix 10 is preferably further provided with guide pins 12, one end of the guide pins 12 is inserted into the prefabricated copper tube 11, and the other end thereof protrudes outside the copper tube and has a tip with a gradually smaller diameter, so that the fins 52 can be guided by the tips of the guide pins 12 and smoothly combed onto the prefabricated copper tube 11. The tip of the guide needle 12 is provided with a limiting soft rubber 13, and the limiting soft rubber 13 is fixedly connected to the tip and is used for supporting the fins 52 and enabling a certain number of fins 52 to be stacked on the tip.

Specifically, in order to smoothly drop the fins 52 onto the copper pipe, a guide pin 12 may be provided at the upper end of the copper pipe, and the fins 52 may be guided by the tip of the guide pin 12. In addition, in order to improve carding efficiency, a limiting flexible glue 13 can be further arranged, so that a plurality of fins 52 can be supported on the guide needle 12, and then the fins are carded to corresponding positions by the carding device 40. For example, 10 fins 52 can be stacked on the spacing flexible glue 13, and then the first carding device 43 is started to card the 10 fins 52, so that the 10 fins 52 are simultaneously carded to the second position 15.

Secondly, it can be understood that the limiting soft rubber 13 is made of a deformable rubber material, and can only form a loose supporting effect on the fin 52, when the fin 52 is combed by the comb tooth mechanism 41 to drive the fin to move downwards, the limiting soft rubber 13 can pass through the through hole of the fin 52 after being deformed, and the combing of the fin 52 is not hindered.

Specifically, the copper tubes in the copper tube matrix 10 are positioned by using the prefabricated positioning mechanism 30, so that the copper tubes are kept in a vertical state mutually matched with the fins 52, the falling fins 52 smoothly fall into the upper end of the copper tubes, and the copper tubes are conveniently and smoothly combed to a preset position by a carding device. The prefabricated positioning mechanism 30 can be provided with clamps 36 with corresponding sizes according to the sizes of copper pipes required to be penetrated, and two clamps 36 which are symmetrically connected with each other are combined to form a group of clamp members 33; then, according to the number of copper tubes in the copper tube matrix 10 and the spacing between the copper tubes, a plurality of groups of clamp members 33 are used for assembling and forming a positioning mechanism 30 at intervals; wherein, the two sides of the positioning mechanism 30 are respectively provided with a sliding rail 31, the two ends of the clamp 36 are respectively provided with a sliding groove 38, and the sliding grooves 38 are connected on the sliding rail 31 in a sliding way, so that the clamp 36 can slide on the positioning mechanism 30; a plurality of groups of positioning blocks 32 are respectively arranged on two sides of the positioning mechanism 30, one group of positioning blocks 32 corresponds to one row of copper pipes, and one group of clamp members 33 corresponds to one group of positioning blocks 32, so that the positions of the clamp members 33, the copper pipes and the positioning blocks 32 correspond to each other; the two ends of each group of clamp members 33 are respectively provided with a positioning notch 34 and a tension spring 35, and the two ends of the tension springs 35 are respectively and fixedly connected to the two clamps 36 of the same group of clamp members 33, so that the two clamps 36 clamp towards the middle under the tension force of the tension springs 35, the positioning notches 34 of the two clamps 36 clamp the corresponding positioning blocks 32, and further the copper pipes clamped by the clamp members 33 are ensured to correspond to the corresponding positioning blocks 32.

Secondly, for relatively long copper tubes, the copper tubes cannot be stabilized by only assisting in positioning by wedging the bottom of the base 20 and the fins 52 on the upper part, and particularly after a certain number of fins 52 are penetrated, certain displacement can occur between the copper tubes and the fins 52, so that the subsequent fins 52 cannot be smoothly combed to the positions where the fins should be positioned. A positioning mechanism 30 can be provided on the copper tube matrix 10 to hold the copper tube by means of a clamp member 33 having a certain thickness, thereby maintaining the stability of the copper tube itself and the stability of the position of the copper tube. In addition, it will be appreciated that a clamping hole 37 is also provided in the clamp member 33, the clamping hole 37 being for the copper tube to pass through, thereby clamping the copper tube.

Again, as shown in fig. 8, preferably, in the initial state, the positioning mechanism 30 is located at the upper end of the copper tube matrix 10, and leaves a space for carding a certain number of fins 52 at the uppermost end of the copper tube; when a certain number of fins 52 fall onto the guide needle 12, the comb device 40 combs the certain number of fins 52, so that the fins move downwards for a certain distance and are in abutting connection with the positioning mechanism 30; then the positioning mechanism 30 moves downwards for a certain distance to make a corresponding space for carding the next group of fins 52, so that the carding device 40 can comb the next group of fins 52; the carding is circulated for a certain number of times until the positioning mechanism 30 moves downwards to the lowest end of the copper tube matrix 10, and then the carding device 40 combs the last group of fins 52 to the uppermost end of the copper tube matrix 10, so that the operation of quickly sleeving the fins 52 on the copper tubes on the whole copper tube matrix 10 is completed.

When the copper tube matrix 10 is used, in the starting stage of sleeving the fins 52, the positioning mechanism 30 can move upwards to the second position 15, the first group of fins 52 are propped against the positioning mechanism 30 after being combed from the first position 14 to the second position 15, and then the positioning mechanism 30 can move downwards for a certain distance, so that a certain space is reserved for combing the fins 52, and the follow-up combing of the fins 52 is facilitated. By analogy, the positioning mechanism 30 is moved downward a distance in sequence, while the fins 52 are continuously combing downward. Until the positioning mechanism 30 moves to the bottommost position, the last group of fins 52 are combed to the uppermost end of the copper tube, thereby completing the operation of quickly sleeving the copper tube of the whole copper tube matrix 10 with the fins 52.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
