Description

Technical Field

[0001] The invention relates to an automatic pipe laying mechanism for a radiator core. Background Art

[0002] When assembling the radiator core, the flat tubes and fins need to be arranged. For example, the flat tubes need to be taken out from the shelf where they are stacked, rotated 90° from the flat state, flipped from the width side down to the width side down, and then arranged one by one in parallel and at intervals, so that the fins can be inserted or put in between the two flat tubes. Since the length and width dimensions of the cross section of the flat tubes are very small, the conversion from the stacked state to the parallel and spaced state is difficult for automated equipment, and there is also the problem of easy collapse. Therefore, the above-mentioned flat tube arrangement is often achieved by manual arrangement or by using manual auxiliary equipment. However, such a pipe arrangement method obviously has the problems of high labor cost and low efficiency. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an automatic pipe arrangement structure which has a simple structure and can automatically flip and arrange flat pipes.

[0004] A radiator core automatic pipe laying mechanism, comprising a frame and a flip pipe laying assembly, specifically,

[0005] The pipe laying assembly includes a pipe laying conveyor belt, a pipe laying conveyor belt, a pipe laying drive, and a pipe laying drive.

[0006] The flip conveyor belt is rotatably mounted on the frame and driven by the flip driving member to circulate. The flip conveyor belt is provided with horizontal and parallel slots, the width of which is greater than or equal to the width of the flat tube and can accommodate a single horizontally placed flat tube.

[0007] The pipe laying conveyor belt is rotatably mounted on the frame and is driven by the pipe laying driving member to rotate cyclically. The pipe laying conveyor belt is provided with parallel and spaced pipe laying grooves. The width of the pipe laying grooves is greater than or equal to the thickness of the flat tube and can accommodate a single flat tube. The interval between the pipe laying grooves is greater than or equal to the thickness of the fin and the fin can be inserted between two flat tubes.

[0008] The feeding end of the pipe laying conveyor belt is located directly below the output end of the flip conveyor belt, and when conveying flat tubes, the feeding end of the flip conveyor belt receives and conveys the flat tubes horizontally placed with the width side facing downward through the card slot, and the flat tubes are gradually flipped to a state with the thickness side facing downward at the discharge end of the flip conveyor belt, that is, flipped 90 degrees, and fall into the pipe laying groove at the feeding end of the pipe laying conveyor belt, and the pipe laying conveyor belt conveys the flat tubes one by one in parallel and at equal intervals through the pipe laying groove. At this time, the flat tubes are automatically flipped from a state with the width side facing downward to a state with the thickness side facing downward and are output in an interval arrangement one by one. The entire flipping pipe laying process has a high degree of automation and does not require manual assistance. At the same time, it also has the advantages of strong continuity and high efficiency.

[0009] Preferably, there are two of the flip conveyor belt and the pipe laying conveyor belt, and they are arranged in parallel and at intervals. It should be noted that the rotating shaft and the card slot of the pulley of the flip conveyor belt are both in the horizontal direction, while the rotating shaft and the pipe laying slot of the pulley of the pipe laying conveyor belt are both in the vertical direction. The flat tube can be placed across the two flip conveyor belts for transportation, and after entering the pipe laying conveyor belt, the two ends enter the pipe laying slots on both sides. The flip driving member and the pipe laying driving member both adopt a relatively simple structure of motor, pulley and belt drive mode, which is easy to install and maintain.

[0010] Preferably, the pipe laying assembly further comprises a mounting seat and a side plate, wherein there are two mounting seats, which are mounted on the frame in parallel and at intervals, and the two pipe laying conveyor belts are respectively mounted on the two mounting seats. The side plate has two pieces, which are respectively mounted on the feed ends of the two mounting seats, and the two flip conveyor belts are respectively mounted on the inner side surfaces of the two side plates.

[0011] Preferably, the top of the side plate is provided with a protective plate along the flip conveyor belt, and the front end of the protective plate is provided with a feed opening, and the width of the feed opening is greater than or equal to the width of the flat tube, so that the flat tubes entering the flip pipe assembly from the outside can be controlled to enter one by one, and during the conveying process on the flip conveyor belt, they are restricted by the baffle and are not easy to fall. In addition, the end of the protective plate extends downward along the discharge end of the flip conveyor belt, and a vertical gap is formed between the end of the protective plate and the discharge end of the flip conveyor belt, and the bottom of the gap points to the feed end of the pipe conveyor belt, so that the flat tube can flip in the gap and fall onto the pipe conveyor belt, thereby improving the success rate and stability of the flipping and falling actions.

[0012] Preferably, the frame includes a crossbeam and a cantilever. The crossbeam is perpendicular to the feeding direction, the top of the cantilever is slidably mounted on the bottom of the crossbeam through a slider and a slide rail, and the bottom end is connected to the mounting seat. The spacing between the two groups of mounting seats and the side plates is adjusted by the movement of the cantilever, so that flat tubes of different lengths can be output. In addition, in order to stabilize the spacing of the conveyor belt, a locking piece is provided between the slider and the slide rail, and the slider and the slide rail are locked after adjustment.

[0013] Preferably, in order to actively release the flat tubes and reduce the setting of parts or robotic arms, the discharge ends of the two tube laying conveyor belts gradually expand outward, and gradually release the flat tubes between the two tube laying grooves through the expansion, so that the laid flat tubes and fins in rows can be pushed out of the end of the flip tube laying assembly.

[0014] Preferably, it also includes a fin feeding assembly, which can feed the fins between two rows of laid flat tubes. The fin feeding assembly includes an inclined feeding trough, a baffle and a sensor. The inclined feeding trough is installed on the frame, and the discharge end extends to the top of the pipe laying conveyor belt, and feeds the fins between the two flat tubes on the pipe laying conveyor belt. The baffle is flipped and installed at the discharge end of the inclined feeding trough, which can buffer the fins that slide down. The sensor is installed on the mounting shaft of the baffle and faces the discharge end of the inclined feeding trough, and can detect whether it is blocked.

[0015] Preferably, it further comprises a receiving assembly, which comprises a delivery trough and a receiving member. The feeding end of the delivery trough is close to the discharging end of the pipe conveyor belt, and can receive a preset number of flat tubes and fin stacking materials and transfer them away.

[0016] The delivery slot is surrounded by two parallel and spaced strip seats. There are four groups of receiving members, which are symmetrically installed on the two strip seats, including receiving driving members and receiving plates. The receiving driving members are installed on the strip seats, and are connected to drive the receiving plates to move back and forth along the direction of the strip seats, and also drive the receiving plates to move up and down to enter or exit the delivery slot.

[0017] Preferably, in order to adjust the size of the delivery slot, the strip seat is also installed at the bottom of the crossbeam of the frame through a cantilever movement, and a width adjustment driver is installed on the frame. The width adjustment driver connects and drives the two strip seats to move closer or farther from each other, and the width adjustment driver adopts a motor, a pulley and a belt drive mode. In addition, the receiving driver adopts a motor, a pulley and a belt drive structure to drive the receiving plate to move along the strip seat, and adopts a cylinder to drive the receiving plate to move up and down.

[0018] Preferably, it also includes a clamping and sending component, which can send out the stacked materials transferred from the receiving component, or transport them to the next radiator assembly structure. The clamping and sending component includes a compound drive and two groups of sending components, and the compound drive includes two suspension seats and a first sending drive. The suspension seat is strip-shaped and parallel to the discharge direction. The top of one suspension seat is suspended and installed above the receiving component through the crossbeam of the frame, and the bottom is relatively movable with the other suspension seat through a track and a slide. The first sending drive is installed on the slide, and a motor, gear and rack drive structure are used to connect and drive the bottom suspension seat to extend or retract from the bottom of the top suspension seat. The two sending components are parallel and spaced and movably installed at the bottom of the suspension seat located at the bottom, including a sending seat, a second sending drive, a third sending drive and a clamp. The sending seat is slidably installed at the bottom of the suspension seat through a track and a slider, and the second sending drive is installed on the sending seat, and a motor, gear and rack drive structure are used to drive the third sending drive to move back and forth along the discharge direction. The third delivery driving member uses a cylinder connected in series and arranged in a vertical direction to drive the clamping plate to move up and down reciprocatingly so as to approach or move away from the discharge end of the receiving component.

[0019] From the above description of the present invention, it can be seen that the present invention has the following beneficial effects:

[0020] 1. The pipe laying mechanism provided by the present invention can automatically flip the flat pipe from the width side facing down to the thickness side facing down and arrange and output them one by one at intervals. The entire flipping pipe laying process has a high degree of automation and does not require manual assistance. At the same time, it also has the advantages of strong continuity and high efficiency.

[0021] 2. The flip conveyor belt and the pipe laying conveyor belt adopt a two-piece structure, which can reduce the overall weight of the equipment, and the contact surface with the flat tube is small, which can reduce the sense of obstruction between the flat tube and the flat tube, and is conducive to the falling action after flipping;

[0022] 3. The described turning pipe laying assembly and receiving assembly are both installed in an interval-adjustable manner, which enables the mechanism to lay out flat pipes of different lengths and specifications;

[0023] 4. The receiving assembly is provided to group the continuously conveyed flat tubes and fins according to the number of pieces required and transfer them out one by one;

[0024] 5.

DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] See also Figures 1 to 8 , a radiator core automatic pipe layout mechanism, including a frame 1 and a flip pipe layout component 2.

[0038] The tube laying assembly 2 includes a tube laying conveyor belt 21, a tube laying drive 22, a tube laying conveyor belt 23 and a tube laying drive 24, wherein:

[0039] The flip conveyor belt 21 is rotatably mounted on the frame 1 and is driven to rotate cyclically by the flip driving member 22. The flip conveyor belt 21 is provided with horizontal and parallel slots 211, the width of which is greater than or equal to the width of the flat tube, and can accommodate a single horizontally placed flat tube.

[0040] The pipe laying conveyor belt 23 is rotatably mounted on the frame 1 and is driven by the pipe laying driving member 24 to rotate in a circular motion. The pipe laying conveyor belt 23 is provided with parallel and spaced pipe laying grooves 231. The width of the pipe laying grooves 231 is greater than or equal to the thickness of the flat tube and can accommodate a single flat tube. The intervals between the pipe laying grooves 231 are greater than or equal to the thickness of the fin and a fin can be inserted between two flat tubes.

[0041] The feeding end of the pipe laying conveyor belt 23 is located directly below the output end of the flip conveyor belt 21, and when conveying flat tubes, the feeding end of the flip conveyor belt 21 receives and conveys the flat tubes horizontally placed with the width side facing downward through the card slot 211. The flat tubes are gradually turned over to a state with the thickness side facing downward at the discharge end of the flip conveyor belt 21, that is, turned over 90 degrees, and fall into the pipe laying groove 231 at the feeding end of the pipe laying conveyor belt 23. The pipe laying conveyor belt 23 conveys the flat tubes one by one in parallel with equal intervals through the pipe laying groove 231. At this time, the flat tubes are automatically turned over from a state with the width side facing downward to a state with the thickness side facing downward and are output in an interval arrangement one by one. The entire flipping pipe laying process has a high degree of automation and does not require manual assistance. At the same time, it also has the advantages of strong continuity and high efficiency.

[0042] In one embodiment, there are two of the flip conveyor belt 21 and the pipe laying conveyor belt 23, and they are arranged in parallel and at intervals. It should be noted that the rotating shaft and the card slot 211 of the pulley of the flip conveyor belt 21 are both in the horizontal direction, while the rotating shaft and the pipe laying slot 231 of the pulley of the pipe laying conveyor belt 23 are both in the vertical direction. The flat tube can be placed across the two flip conveyor belts 21 for transportation, and after entering the pipe laying conveyor belt 23, the two ends enter the pipe laying slots 231 on both sides. The flip driving member 22 and the pipe laying driving member 24 both adopt a relatively simple structure of motor, pulley and belt drive mode, which is easy to install and maintain.

[0043] On the basis of the above embodiment, regarding the specific installation structure of the flip pipe assembly 2, in one embodiment, the flip pipe assembly 2 further includes a mounting seat 25 and a side plate 26, wherein there are two mounting seats 25, which are installed on the frame 1 in parallel and at intervals, and the two pipe conveyor belts 23 are respectively installed on the two mounting seats 25. The side plate 26 has two pieces, which are respectively installed at the feeding ends of the two mounting seats 25, and the two flip conveyor belts 21 are respectively installed on the inner side surfaces of the two side plates 26.

[0044] Preferably, a protective plate is provided on the top of the side plate 26 along the flip conveyor belt 21, and a feed opening 261 is provided at the front end of the protective plate. The width of the feed opening 261 is greater than or equal to the width of the flat tube, so that the flat tubes entering the flip pipe assembly 2 from the outside can be controlled to enter one by one, and during the conveying process on the flip conveyor belt 21, they are restricted by the baffle 32 and are not easy to fall. In addition, the end of the protective plate extends downward along the discharge end of the flip conveyor belt 21, and a vertical gap 262 is formed between the end of the protective plate and the discharge end of the flip conveyor belt 21, and the bottom of the gap 262 points to the feed end of the pipe conveyor belt 23, so that the flat tube can be flipped in the gap 262 and fall onto the pipe conveyor belt 23, thereby improving the success rate and stability of the flipping and falling actions.

[0045] In another embodiment, the frame 1 includes a crossbeam 11 and a cantilever 12. The crossbeam 11 is perpendicular to the feeding direction, and the top of the cantilever 12 is slidably mounted on the bottom of the crossbeam 11 through a slider and a slide rail, and the bottom end is connected to the mounting seat 25. The spacing between the two groups of mounting seats 25 and the side plates 26 is adjusted by the movement of the cantilever 12, so that flat tubes of different lengths can be matched. In addition, in order to stabilize the spacing of the conveyor belt, a locking piece is provided between the slider and the slide rail, and the slider and the slide rail are locked after adjustment.

[0046] On the basis of the above embodiments, in order to actively release the flat tubes and reduce the setting of parts or robotic arms, in one embodiment, the discharge ends of the two pipe laying conveyor belts 23 gradually expand outward, and gradually release the flat tubes between the two pipe laying grooves 231 through expansion, so that the flat tubes and fins laid one by one can be pushed out of the end of the flip pipe laying assembly 2.

[0047] In one embodiment, the tube laying mechanism further includes a fin feeding assembly 3 , which can feed the fins between two rows of laid flat tubes. The fin feeding assembly 3 includes an inclined feeding trough 31 , a baffle 32 and an inductor 33 .

[0048] The inclined feed trough 31 is installed on the frame 1, and the discharge end extends to the top of the pipe conveyor belt 23, and feeds the fins between the two flat tubes on the pipe conveyor belt 23. The baffle 32 is flipped and installed at the discharge end of the inclined feed trough 31, which can buffer the fins that slide down. The sensor 33 is installed on the mounting shaft of the baffle 32 and faces the discharge end of the inclined feed trough 31, and can detect whether it is blocked. The feed end of the inclined feed trough 31 can directly connect to the retractable conveyor belt at the discharge end of the fin forming machine.

[0049] In one embodiment, the pipe laying mechanism further includes a receiving assembly 4, which includes a delivery trough 41 and a receiving member 42. The feeding end of the delivery trough 41 is close to the discharging end of the pipe laying conveyor belt 23, and can receive a preset number of flat tubes and fin stacks and transfer them away.

[0050] Specifically, the delivery trough 41 is surrounded by two parallel and spaced strip seats 411. The receiving members 42 have four groups, which are symmetrically installed on the two strip seats 411 (or three groups of receiving members 42 can also be provided, of which two groups are symmetrically provided at the discharge end close to the discharge trough 41, and only one group is provided on the side close to the feed end), including a receiving driving member 421 and a receiving plate 422. The receiving driving member 421 is installed on the strip seat 411, and is connected to drive the receiving plate 422 to reciprocate along the direction of the strip seat 411, and also drives the receiving plate 422 to reciprocate up and down to enter or exit the delivery trough 41.

[0051] On the basis of the above embodiment, in order to achieve that the delivery slot 41 can also adjust the size, in one embodiment, the strip seat 411 is also installed at the bottom of the crossbeam 11 of the frame 1 through the cantilever 12, and a width adjustment driver 13 is installed on the frame 1. The width adjustment driver 13 connects and drives the two strip seats 411 to move closer or farther from each other, and the width adjustment driver 13 adopts a motor, a pulley and a belt drive mode. In addition, the receiving driver 421 also uses a motor, a pulley and a belt drive structure to drive the receiving plate 422 to move along the strip seat 411. Preferably, the receiving driver 421 located on the same strip seat 411 adopts the same set, and then a cylinder is used to drive the receiving plate 422 to move up and down.

[0052] In one embodiment, the pipe laying mechanism further includes a clamping and delivering component 5, which can deliver the stacked materials transferred from the receiving component 4, or transport them to the next radiator assembly structure.

[0053] The clamping and delivering assembly 5 includes a compound driving member 51 and two groups of delivering members 52. The compound driving member 51 includes two suspension seats 511 and a first delivering driving member 512. The suspension seat 511 is strip-shaped and parallel to the discharging direction. The top of one of the suspension seats 511 is suspended and installed above the receiving assembly 4 through the crossbeam 11 of the frame 1, and the bottom is relatively movable and installed with the other suspension seat 511 through a track and a slide. The first delivering driving member 512 is installed on the slide, and is connected by a motor, gear and rack drive structure to drive the bottom suspension seat 511 to extend or retract from the bottom of the top suspension seat 511. The two delivering members 52 are parallel and spaced and movably installed at the bottom of the suspension seat 511 at the bottom, including a delivering seat 521, a second delivering driving member 522, a third delivering driving member 523 and a clamping plate 524. The delivery seat 521 is slidably mounted on the bottom of the suspension seat 511 through a track and a slider, and the second delivery drive member 522 is mounted on the delivery seat 521, and a motor, gear and rack drive structure are used to drive the third delivery drive member 523 to reciprocate along the discharge direction. The third delivery drive member 523 uses a cylinder connected in series and arranged in a vertical direction to drive the clamping plate 524 to reciprocate up and down to approach or move away from the discharge end of the receiving assembly 4.

[0054] The working principle of the pipe laying mechanism provided in this embodiment is:

[0055] The stacked flat tubes enter the slot 211 of the flip tube assembly 2 one by one through the feed opening 261 of the flip tube assembly 2 and are transported out. When the flat tubes reach the discharge end of the flip tube assembly 2, they gradually flip from the width side down state to the thickness side down state, and finally fall at the end of the flip tube assembly 2 and fall into the tube groove 231 of the tube conveyor belt 23, and are gradually transported out by the tube conveyor belt 23. In the process of transporting out, the fin feeding assembly 3 delivers the fins one by one between the two flat tubes. Since the end of the tube conveyor belt 23 adopts a mechanism that gradually expands outward, the flat tubes between the two tube grooves 231 can be gradually released by expansion, so that the flat tubes and fins arranged one by one can be pushed out of the end of the tube conveyor belt 23. When the flat tubes and fins arrive at the working station of the receiving component 4, the receiving piece 42 close to the end of the receiving component 4 first approaches the end of the pipe conveyor belt 23, and receives the flat tubes and fins that are gradually sent over. At the same time, it gradually retreats backwards along the delivery groove 41. When a preset number of flat tubes and fins are received, the receiving plate 422 of the other receiving piece 42 also enters the delivery groove 41, and divides the flat tubes that will continue to be delivered and the flat tubes that have been delivered into two parts, and the flat tubes and fins between the two receiving pieces 42 are gradually transferred to the end of the receiving component 4, and are replaced by the two delivery pieces 52 of the clamping delivery component 5 to continue to transfer the group of flat tubes and fins, and the two receiving pieces 42 return to the initial position to receive, divide and transfer the next group of flat tubes and fins.

[0056] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
