Technical Field

[0001] The present application relates to the technical field of heater assembly, and in particular to a heater assembly device. Background Art

[0002] A heater is a type of heat exchanger that is used to transfer heat from a fluid with a higher temperature to a fluid with a lower temperature.

[0003] Reference Figure 1 and Figure 2 As shown, there is currently a heater comprising a plurality of parallel flat tubes 1, two main plates 2 plugged into the ends of the plurality of flat tubes 1, and fins 3 distributed between adjacent flat tubes 1. The main plates 2 are provided with a plurality of plug-in ports 21 for plugging into the flat tubes 1. The notches of the plug-in ports 21 are protruding in a direction away from the flat tubes 1, i.e., plug-in grooves 22 are formed between the notches of adjacent plug-in ports 21.

[0004] The heater and condenser have similar structures and similar assembly methods. Figure 3 As shown, in actual assembly, reference can be made to a condenser assembly platform disclosed in publication number CN216883829U, which includes a base 4, a table plate 41 for supporting flat tubes is provided in the middle of the base, and an alignment limit component 5 is slidingly provided on the table plate to neatly arrange the flat tubes. The alignment limit component 5 slides in the direction of approaching and away from the table plate 41, and the alignment limit component 5 includes a limit main plate 51 and a limit sub-plate 52. An alignment plate 511 is provided on the side of the limit main plate 51 close to the table plate 41, and a plurality of comb teeth 512 are connected to the alignment plate 511, and a limiting gap 513 is formed between each two of the comb teeth 512. The base 4 is also provided with an abutment component 6 for tightly fitting the flat tubes.

[0005] The staff slides the alignment limit component close to the table, places the flat tube on the table, and plugs it into the limit gap. That is, the alignment limit component is used to place all the flat tubes neatly, and then the fins are inserted between adjacent flat tubes. The abutment component is then used to abut the flat tubes on both sides to fix the whole. Then the alignment limit component is slid out, the two main pieces are aligned with the flat tubes and plugged in to form an interference fit, the condenser is formed, and the assembly operation of the condenser is completed.

[0006] The above-mentioned condenser assembly table can also be used for the assembly of heaters. During the assembly process, a semi-automatic method is adopted, but the flat tubes are placed on the table manually, and the staff are required to place them one by one into the limit gap, which is more troublesome and prolongs the entire assembly time, that is, it is inefficient. Summary of the Invention

[0007] In order to improve the assembly efficiency of the condensing table, the present application provides a heater assembly device.

[0008] The present application provides a heater assembly device that adopts the following technical solution:

[0009] A heater assembly device comprises a machine body, a table for supporting flat tubes is provided on the machine body, limit plates are provided on both sides of the machine body located on the table, a driving assembly is provided on the machine body for driving the limit plates to move in a direction close to or away from the table, a plurality of limit gaps for limiting and fixing the flat tubes are formed on the side where the two limit plates are close to each other, a tightening assembly for tightening the flat tubes and fins is provided on the machine body located on the table, and a feeding assembly is provided on the machine body;

[0010] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0011] The machine body is provided with a sliding assembly for driving the two mounting plates to slide. The sliding directions of the mounting plate, the supporting plate and the blanking plate are parallel. The mounting plate slides in the direction of approaching and moving away from the table. When the sliding assembly drives the two mounting plates to move above the table, the sliding member drives the blanking plate to move so that the blanking gap is connected with the supporting gap.

[0012] By adopting the above technical solution, the flat tubes are stacked and placed in the discharge trough, and then fall into the lowermost end of the discharge trough. Under the action of the conveying component, the flat tubes are driven to be conveyed in the conveying trough until they are conveyed into the supporting gap. In this process, the moving component drives the supporting plate to slide, so that the flat tubes fall into different supporting gaps in turn. At this time, the unloading gap and the supporting gap on the unloading plate are misaligned, that is, the unloading plate plays a supporting role; when all the supporting gaps fall into the flat tubes, the sliding component drives the mounting plate to slide, and at the same time drives the supporting plate and the unloading plate to move together until they move to the top of the table, and then the sliding component drives The dynamic blanking plate slides so that the blanking gap is connected with the supporting gap. At this time, the flat tube will fall from the supporting gap onto the table plate and enter the limit gap, completing the loading operation of the flat tube. Using this method, when the staff performs subsequent assembly work, the loading component can arrange the flat tubes in advance and then directly load them. Compared with manual arrangement, the work efficiency is high and the degree of automation is high. After completing the loading of the flat tubes, the staff inserts the fins between adjacent flat tubes, and then presses the assembly to press the flat tubes and fins. The driving assembly then drives the limit plate away from the flat tube, and then the main piece can be plugged in to realize the assembly operation of the heater.

[0013] Preferably, the sliding assembly includes a sliding plate and a first driving member, the two mounting plates are fixed on the sliding plate, the sliding plate is rotatably connected to a rotating shaft, the first driving member drives the rotating shaft to rotate, and first gears are coaxially fixed at both ends of the rotating shaft, and the body is located on both sides of the sliding plate. A first rack is provided, and the two first gears correspond one-to-one with the two first racks, and the first gear is engaged with the corresponding first rack.

[0014] By adopting the above technical solution, the first driving member drives the rotating shaft to rotate, driving the two first gears to rotate. Due to the engagement of the first gear and the first rack, the sliding plate will slide in the length direction of the first rack, thereby driving the mounting plate to slide. When the mounting plate moves to above the table, the flat tube is lowered, thereby realizing the loading operation of the flat tube.

[0015] Preferably, the conveying component includes a conveying chain and several conveying blocks arranged at intervals on the conveying chain. A plurality of sprockets are rotatably connected to the mounting plate. A second driving member for driving the sprocket to rotate is provided on the sliding plate. The conveying chain is wound around the sprocket, and the winding shape of the conveying chain is adapted to the shape of the conveying trough. When the conveying block moves to the lower end of the discharge trough, the conveying block pushes the bottom layer of flat tubes into the conveying trough for conveying.

[0016] By adopting the above technical solution, after the flat tubes are placed in the discharge trough, the second driving member drives the conveying chain to rotate, and the conveying block moves accordingly. Under the action of the conveying block, the bottom layer of flat tubes is pushed into the conveying trough and conveyed, thereby realizing the conveying operation of the flat tubes; when the flat tubes enter the output end of the conveying trough, the flat tubes will slide in the conveying trough due to gravity and move to the previous conveying block, abutting against the conveying block, which helps prevent the flat tubes from directly falling out of the conveying trough, and further helps the flat tubes fall into different supporting gaps in sequence.

[0017] Preferably, the support plate is slidably matched with the two mounting plates, and the moving assembly includes a second gear, a second rack and a third driving member for driving the second gear to rotate. Two second gears are provided and are rotatably connected on the side of the two mounting plates away from each other. Two second racks are provided and are both provided on the support plate. The two second racks correspond one-to-one to the two second gears and the second gear is meshed with the second rack.

[0018] By adopting the above technical solution, the third driving member drives the second gear to rotate, and under the engagement of the second gear and the second rack, the second rack moves, thereby realizing the sliding of the support plate, and realizing that multiple flat tubes fall one by one into the supporting gap of the support plate.

[0019] Preferably, the machine body is provided with moving blocks on both sides of the table for horizontal sliding, the driving assembly drives the moving blocks to slide, and the two moving blocks slide in the direction of approaching and away from the table, the moving blocks are hinged with abutment plates, the moving blocks are provided with rotating parts for driving the abutment plates to rotate, the abutment plates are provided with plug-in blocks that are plugged into the plug-in slots on the main plate, and the limit plates are provided on the corresponding abutment plates.

[0020] By adopting the above technical solution, when the flat tube is loaded and the fin is placed, the clamping assembly presses the flat tube and the fin, and the moving block first slides to the side away from the table, so that the limit plate is separated from the flat tube, and then the rotating part drives the abutment plate to rotate, so that the main piece inserted on the abutment plate faces the flat tube, and then the moving block slides to one side of the table, so that the main piece and the flat tube form an interference fit, thereby realizing the assembly between the flat tube and the main piece.

[0021] Preferably, a clamping block is provided on the abutment plate, and the plug-in block is provided on the clamping block. A plug-in column is provided on the side of the clamping block close to the abutment block, and the plug-in column slides with the abutment plate. A compression spring is sleeved on the plug-in column, one end of the compression spring is fixed to the abutment plate, and the other end of the compression spring is fixed to the clamping block. The clamping block is located between adjacent plug-in blocks to form a sliding groove, and a plurality of flaring knives are provided on the side of the abutment plate close to the clamping block, and the flaring knives correspond one-to-one to the sliding grooves, and the flaring knives are plugged and slidably fitted with the corresponding sliding grooves.

[0022] By adopting the above technical solution, after the main plate is plugged into the flat tube, the moving block drives the abutment plate to continue to move toward one side of the table. At this time, the clamping block does not move, the compression spring is compressed, and the abutment plate drives the flaring knife to continue to move. At this time, the flaring knife passes through the sliding groove and is plugged into the flat tube to perform flaring operation on the flat tube, which helps to prevent deformation of the flat tube mouth.

[0023] Preferably, the rotating member is configured as an articulated cylinder, a cylinder body of the articulated cylinder is articulated to the moving block, and an end portion of a piston rod of the articulated cylinder is articulated to the abutment plate.

[0024] By adopting the above technical solution, the articulated cylinder is operated to drive the abutment plate to rotate on the moving block, thereby realizing the rotation of the main piece, thereby facilitating the subsequent connection between the main piece and the flat tube.

[0025] Preferably, a plurality of linkage blocks are slidingly provided on the limit plate, the limit block is detachably connected to the linkage block, comb teeth are provided on the limit block, the limit gap is formed between adjacent comb teeth, and an adjustment member for synchronously adjusting the distance between all adjacent limit blocks is provided on the abutment plate.

[0026] By adopting the above technical solution, the distance between adjacent limit blocks is increased in advance by using the adjusting parts, that is, the size of some limit gaps becomes larger. After the flat tubes are loaded, it is convenient for the staff to insert the fins between the flat tubes. Using this method, it helps the staff to quickly complete the assembly of the fins, that is, it helps to improve the overall assembly efficiency. Then the adjusting parts make the limit gaps smaller, which facilitates the subsequent insertion of the main piece.

[0027] Preferably, connecting blocks are provided between adjacent linkage blocks, and the connecting blocks include a sliding portion and locking portions provided at both ends of the sliding portion, and the two adjacent linkage blocks are slidably matched with the sliding portion of the connecting blocks, and the adjusting component is configured as an adjusting cylinder, wherein the linkage block at one end is fixed to the piston rod of the adjusting cylinder, and the linkage block at the other end is fixed to the limit plate, and the telescopic direction of the adjusting cylinder is parallel to the distribution direction of the limit block. When the piston rod of the adjusting cylinder contracts, the distance between the adjacent linkage blocks will increase, and at this time the linkage block and the locking portion of the connecting block abut and cooperate.

[0028] By adopting the above technical solution, when the piston rod of the adjusting cylinder is extended, the adjacent linkage blocks will slide on the sliding part and all move toward the linkage block on the fixed side, so that the distance between the adjacent limit blocks becomes smaller, that is, the limit gap becomes smaller. Conversely, the piston rod of the adjusting cylinder contracts, so that the distance between the adjacent limit blocks becomes larger, and the sliding position of the linkage block is limited by the locking part, so that the distance between the limit blocks becomes larger, that is, the limit gap becomes larger.

[0029] Preferably, the clamping assembly includes a fixed plate, a movable plate and a driving component that drives the movable plate to slide toward and away from the fixed plate. The fixed plate is fixed on the table, and a placement space for the flat tube is formed on the table between the movable plate and the fixed plate.

[0030] By adopting the above technical solution, the driving component is used to drive the movable plate to move toward the fixed plate, so that the movable plate abuts against the flat tube, that is, the flat tube and the fin are tightly pressed and limited, which facilitates the subsequent insertion of the main plate.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The flat tubes are stacked in the discharge gap, and then the conveying components are used to drive the flat tubes to move in the conveying trough until they fall into the supporting gap. The sliding assembly then drives the entire assembly to move until the supporting plate moves above the table. The sliding drive then moves the unloading plate so that the unloading port is connected to the supporting gap. At this time, the flat tubes will fall from the supporting gap onto the table and enter the limit gap, completing the loading operation of the flat tubes. In this way, while the flat tubes are entering the supporting gap, the staff can carry out the subsequent assembly operation of the previous heater, saving the work of arranging the flat tubes, which helps to improve the overall assembly efficiency of the heater.

[0033] 2. With the help of the flaring knife, when the abutting plate moves toward the side of the table, the pressing plate does not move, and the flaring knife continues to move toward the side of the flat tube to flare the flat tube mouth, which helps to prevent the flat tube mouth from deformation;

[0034] 3. Use linkage blocks and connecting blocks to increase and decrease the limit gap. First, increase the limit gap and then place the flat tubes. The gap between the flat tubes is larger, which is convenient for placing the fins. After the fins are placed, reduce the limit gap to make the flat tubes and fins fit tightly.

DETAILED DESCRIPTION

[0049] The following is combined with Figure 4-13 This application is described in further detail.

[0050] An embodiment of the present application discloses a heater assembly device.

[0051] Reference Figure 4 The heater assembly equipment includes a body 1, which is fixedly connected to a table 11 supporting flat tubes. The table 11 is rectangular, and the body 1 is provided with limit plates 2 on both sides of the length direction of the table 11 for limiting all flat tubes. The body 1 is provided with a driving component 4 for driving the limit plate 2 to move in the direction of approaching and away from the table 11. The body 1 is provided with a tightening component 5 on the table 11 for tightening the flat tubes and fins. The tightening direction of the tightening component 5 is consistent with the length direction of the table 11. The body 1 is provided with a loading component 6 for loading materials onto the table 11, which is used to transport the neatly arranged flat tubes to the table 11.

[0052] Reference Figure 4 and Figure 5The loading assembly 6 includes two relatively arranged mounting plates 61, the mounting plate 61 is formed with a vertical portion 611 and a conveying portion 612, the mounting plate 61 is located on the vertical portion 611 and is provided with a discharge trough 6111, the discharge trough 6111 is vertically arranged, and a discharge gap 6112 for placing the flat tube is formed between the two discharge troughs 6111 on the two mounting plates 61, the mounting plate 61 is located at the conveying portion 612 and is provided with a conveying trough 6121, the conveying trough 6121 is arc-shaped, and the two conveying troughs 6121 form a conveying gap 6122 for conveying the flat tube, the input end of the conveying trough 6121 is horizontally arranged, and the input end of the conveying trough 6121 is connected to the lower end of the corresponding discharge trough 6111, and the output end of the conveying trough 6121 is vertically arranged, and the loading assembly 6 also includes a conveying component 62 for driving the flat tube to move in the conveying trough 6121.

[0053] Reference Figure 4 and Figure 6 , a sliding assembly 7 for driving the two mounting plates 61 to slide is provided on the machine body 1. The sliding direction of the two mounting plates 61 is parallel to the length direction of the table 11. The sliding assembly 7 includes a sliding plate 71 and a first driving member 72. The two mounting plates 61 are fixed to the sliding plate 71 by bolts. A rotating shaft 711 is rotatably connected to the sliding plate 71 through a bearing. The rotating axis of the rotating shaft 711 is horizontal and perpendicular to the length direction of the table 11. A first gear 712 is coaxially fixed at both ends of the rotating shaft 711. The machine body 1 is located at both ends of the sliding plate 71 and is fixed with a first rack 12. The two The first rack 12 corresponds to the two first gears 712 one by one, and the first gear 712 is meshed with the corresponding first rack 12. The first driving member 72 adopts a motor. The first driving member 72 is fixedly mounted on the sliding plate 71, and the first driving member 72 is connected to the rotating shaft 711 through a pulley assembly. When the first driving member 72 is operated, the rotating shaft 711 is driven to rotate through the pulley assembly, and then the first gear 712 is driven to rotate. Under the meshing action of the first gear 712 and the first rack 12, the movement of the sliding plate 71 is realized, and then the movement of the two mounting plates 61 toward the table 11 is realized.

[0054] Reference Figure 5 、 Figure 7 and Figure 8 The lower sides of the two mounting plates 61 are both slidably fitted with supporting plates 8. A moving component 9 is provided on the mounting plate 61 for driving the two supporting plates 8 to slide. A plurality of supporting openings 81 are provided on the supporting plate 8. The two supporting openings 81 corresponding to the two supporting plates 8 form a supporting gap 82. The supporting gap 82 is connected to the output end of the conveying trough 6121, that is, the supporting gap 82 is connected to the conveying gap 6122. The moving component 9 drives the two supporting plates 8 to move in a step-by-step manner, so that the flat tubes enter different supporting gaps 82 in turn.

[0055] Reference Figure 5 、 Figure 7 and Figure 9 , there is a blanking plate 10 sliding under the two supporting plates 8, and a sliding part 20 is provided on the supporting plate 8 to drive the blanking plate 10 to slide. A plurality of blanking ports 101 are spaced apart on the blanking plate 10, and the two blanking ports 101 corresponding to the two blanking plates 10 form a blanking gap 102. Since the adjacent blanking ports 101 are densely spaced, in the process of unloading the flat tube from the conveying trough 6121, the blanking gap 102 and the supporting gap 82 are staggered. At this time, the blanking plate 10 supports the flat tube. When the sliding plate 71 drives the mounting plate 61 to move to the side of the table plate 11, when the supporting plate 8 moves to above the table plate 11, the sliding part 20 drives the blanking plate 10 to move, so that the blanking gap 102 is connected with the supporting gap 82. At this time, the flat tube will fall onto the table plate 11, realizing the loading operation of the flat tube.

[0056] The sliding member 20 is configured as a driving cylinder, which is fixedly mounted between the two mounting plates 61. The ends of the two blanking plates 10 away from the table 11 are connected to a connecting plate 103. The piston rod end of the driving cylinder is fixedly fixed to the connecting plate. The extension and contraction direction of the driving cylinder piston rod is consistent with the sliding direction of the sliding plate 71. The movement of the blanking plates 10 is achieved by the extension and contraction of the driving cylinder piston rod.

[0057] Reference Figure 5 The conveying component 62 includes a conveying chain 621 and a conveying block 622. The two mounting plates 61 are symmetrically arranged. Taking one of the mounting plates 61 as an example for explanation, the inner side of the mounting plate 61 is rotatably connected with three sprockets 613. The conveying chain 621 is wound around the three sprockets 613, and the shape of the conveying chain 621 is a right-angled triangle. The two right-angled sides of the conveying chain 621 correspond to the horizontal and vertical sections of the conveying trough 6121, that is, the winding shape of the conveying chain 621 is adapted to the shape of the conveying trough 6121. A second driving member 713 for driving the sprocket 613 to rotate is fixedly installed on the sliding plate 71. The second driving member 713 adopts a motor, wherein the two symmetrical sprockets 613 on the two mounting plates 61 are coaxially connected by a rotating shaft, and the output shaft of the second driving member 713 is fixedly connected to the rotating shaft. When the second driving member 713 is running, the movement of the two conveying chains 621 can be realized.

[0058] Reference Figure 5 and Figure 8, there are multiple conveying blocks 622, which are distributed at intervals on the conveying chain 621 and fixed to the conveying chain 621. A pushing block 6221 is integrally formed on the conveying block 622. During the movement of the conveying chain 621, the pushing block 6221 on the conveying block 622 will push the flat tube at the bottom of the discharge trough 6111 into the conveying trough 6121, and under the action of the pushing block 6221, the flat tube continues to move in the conveying trough 6121. When the flat tube moves to the vertical section of the conveying trough 6121, the flat tube will break away from the pushing block 6221 due to gravity and slide along the conveying trough 6121 to the pushing block 6221 of the previous conveying block 622. At this time, the pushing block 6221 plays a role in preventing the flat tube from falling. When the conveying block 622 continues to move along the conveying chain 621 and turns, the flat tube will fall away from the supporting gap 82 below due to gravity.

[0059] Reference Figure 5 , since the two supporting plates 8 are symmetrically arranged and the relevant structures are the same, one of them is now used as an example for explanation. A sliding groove is provided on the inner side of the supporting plate 8, and a sliding connection is achieved with the corresponding mounting plate 61 through a slider or a pulley, and at the same time, the mounting plate 61 and the supporting plate 8 are limited together; the moving assembly 9 includes a second gear 91, a second rack 92 and a third driving member 93 for driving the second gear 91 to rotate. The second gear 91 is rotatably connected to the outer side of the mounting plate 61, the second rack 92 is fixed on the supporting plate 8, and the second The length direction of the rack 92 is consistent with the sliding direction of the sliding plate 71. The second gear 91 and the second rack 92 are meshed. The third driving member 93 adopts a stepping motor and is fixedly installed under the sliding plate 71. The two second gears 91 are coaxially connected through a rotating shaft. The output shaft of the third driving member 93 is fixed to the rotating shaft. When the third driving member 93 drives the rotating shaft to rotate, the second gear 91 rotates, driving the supporting plate 8 to move along the length direction of the second rack 92, thereby realizing a one-to-one correspondence between multiple supporting gaps 82 and the flat tubes.

[0060] Reference Figure 4 The abutting assembly 5 includes a fixed plate 51, a movable plate 52, and a driving component 53 that drives the movable plate 52. A placement space 54 for accommodating flat tubes is formed between the fixed plate 51 and the movable plate 52. The fixed plate 51 is fixedly mounted on the end of the table 11 away from the mounting plate 61. The movable plate 52 is slidably connected to the side of the table 11 away from the fixed plate 51 via a slider slot 83. The driving component 53 adopts a screw slide structure and is fixedly mounted on the machine body 1, with the movable plate 52 fixed to the slide of the driving component 53. When the driving component 53 operates, the movable plate 52 slides toward and away from the fixed plate 51.

[0061] Reference Figure 4 and Figure 10Since the structures on both sides of the length direction of the table 11 are symmetrically arranged, the relevant structural principles are the same. Here, one side is taken as an example for explanation. The body 1 is located on one side of the length direction of the table 11 and slides horizontally with a moving block 30. The driving component 4 drives the moving block 30 to move. The driving component 4 adopts a screw slide. The moving block 30 is fixed on the slide of the screw slide, and the screw adopts a bidirectional screw. Both ends of the bidirectional screw are fixed with a slide to realize the synchronous movement of the moving blocks 30 on both sides; the moving block 30 slides in the direction of approaching and moving away from the table 11, and the moving block 30 is integrally formed There are two hinge blocks 301, and the moving block 30 is hinged to the abutment plate 40 through the two hinge blocks 301. The side of the abutment plate 40 close to the table 11 is hinged to the hinge block 301. The moving block 30 is provided with a rotating member 302 for driving the abutment plate 40 to rotate. The rotating member 302 adopts a hinge cylinder, one end of the hinge cylinder is hinged to the moving block 30, and the other end is hinged to the lower side of the abutment plate 40, and the hinge point is located on the side of the abutment plate 40 away from the table 11. When the abutment plate 40 is in a horizontal state, the lower side of the abutment plate 40 is overlapped on the two hinge blocks 301.

[0062] Reference Figure 11 and Figure 12 The abutment plate 40 is provided with a clamping block 401, and a plurality of plug-in blocks 402 are integrally formed on the clamping block 401. All the plug-in blocks 402 are spaced apart and plugged into the plug-in slots of the main plate. The limiting plate 2 is integrally formed on the abutment plate 40. When the abutment plate 40 is in a horizontal state, the limiting plate 2 is located on the side of the abutment plate 40 close to the table 11. A plug-in column 4011 is integrally formed on the side of the clamping block 401 close to the abutment plate 40. The plug-in column 4011 plugs and slides with the limiting plate 2. A compression spring 4012 is sleeved on the plug-in column 4011. One end of the compression spring 4012 is fixed to the clamping block 401, and the other end is fixed to the abutment plate 40. The main piece is pre-installed on the plug-in block 402. When the flat tube has completed the loading operation, the driving component 4 drives the moving block 30 away from the table 11, and the rotating member 302 drives the abutment plate 40 to rotate. Then the driving component 4 drives the moving block 30 to move to the side of the table 11. At this time, the main piece will be plugged into the flat tube and finally withdraw from the abutment plate 40 to complete the assembly operation of the main piece.

[0063] Reference Figure 11 and Figure 12The pressing blocks 401 are located between adjacent plug-in blocks 402, forming sliding grooves 4021 that correspond to the plug-in ports on the main plate. Multiple flaring blades 403 are mounted on the side of the abutment plate 40 near the pressing blocks 401. These blades 403 correspond one-to-one with the sliding grooves 4021, forming a plug-in and sliding fit. The ends of the flaring blades 403 are surrounded by inwardly tapering guide surfaces. Each flaring blade 403 is plugged into the abutment plate 40 and secured with latches. When the abutment plate 40 moves toward the side of the table 11, and the two ends of the clamping block 401 have abutted against the movable plate 52 and the top plate, the clamping block 401 cannot move forward at this time. Under the action of the compression spring 4012, the abutment plate 40 can continue to move, driving the flaring knife 403 to move. The flaring knife 403 extends from the sliding groove 4021 and forms a plug-in fit with the flat tube mouth, thereby stretching the flat tube mouth and helping to prevent the flat tube mouth from deformation.

[0064] Reference Figure 11 and Figure 13 The limit plate 2 is provided with several linkage blocks 21 for sliding along the length direction of the table 11. The linkage block 21 and the limit plate 2 are slidably connected through a T-block structure. The side of the linkage block 21 close to the table 11 is detachably connected to the limit block 211 through a dovetail structure. Three comb teeth 212 are integrally formed on the limit block 211, and a limit gap 213 is formed between adjacent comb teeth 212. An adjusting member 404 for synchronously adjusting the distance between adjacent limit blocks 211 is fixedly connected to the abutment plate 40 to adjust the adjacent limit blocks 211, that is, to adjust the limit gap 213 between adjacent comb teeth 212 on adjacent limit blocks 211.

[0065] A connecting block 50 is provided between adjacent linkage blocks 21. The connecting block 50 includes a sliding portion 501 and a locking portion 502 located at both ends of the sliding portion 501. Mounting grooves 214 are provided on both sides of the linkage block 21. The sliding portion 501 of the connecting block 50 is inserted into the mounting groove 214 on the side close to the two adjacent linkage blocks 21, and the linkage block 21 is slidingly connected to the sliding portion 501 of the connecting block 50. The locking portion 502 of the connecting block 50 is larger than the size of the notch of the mounting groove 214 and is used to lock the linkage block 21.

[0066] The adjusting member 404 is configured as an adjusting cylinder, which is fixedly mounted on the abutment plate 40. The end of the adjusting cylinder's piston rod is bolted to the linkage block 21 at one end, while the linkage block 21 at the other end is fixed to the abutment plate 40. The extension and retraction direction of the adjusting cylinder's piston rod aligns with the distribution direction of the linkage blocks 21. When the adjusting cylinder's piston rod extends, all linkage blocks 21 slide toward the other end, reducing the distance between adjacent limit blocks 211 and, in other words, reducing some of the limit gaps 213.

[0067] When the piston rod of the regulating cylinder contracts, adjacent linkage blocks 21 slide on the limit plate 2, and under the action of the connecting block 50, a chain-driven effect is formed, which increases the distance between the adjacent linkage blocks 21, that is, the limit gap 213 between adjacent limit blocks 211. Before the fins are installed, the limit gap 213 is increased to facilitate the installation of the fins. After the installation is completed, the limit gap 213 is reduced to ensure a close contact between the flat tubes and the fins, which facilitates the subsequent assembly of the main plate.

[0068] The implementation principle of a heater assembly device in an embodiment of the present application is: the stacked flat tubes are placed in the discharge gap 6112 in advance, and the main sheet is pre-fixed on the clamping plate, the conveying chain 621 drives the conveying block 622 to move, and the pushing block 6221 drives the flat tubes into the conveying gap 6122, and then the flat tubes fall from the conveying gap 6122 into the supporting gap 82. During this process, the moving component 9 drives the supporting plate 8 to move in a step-by-step manner, so that multiple flat tubes fall into different supporting gaps 82 in turn.

[0069] When the blanking is completed, the sliding assembly 7 drives the sliding plate 71 to move to the side of the table 11, so that the supporting plate 8 is located above the placement space 54 of the table 11. At this time, the supporting member limit gaps 213 correspond one to one, and the sliding member 20 drives the blanking plate 10 to slide, so that the blanking gap 102 is connected to the supporting gap 82. At this time, the flat tube will fall from the supporting gap 82 onto the table 11 below, and the two ends of the flat tube are respectively inserted into the limit gaps 213 on both sides to complete the loading operation of the flat tube.

[0070] Then the sliding plate 71 slides to the side away from the table 11 and continues the unloading operation. At this time, the staff places the fins between the adjacent flat tubes. After completion, the cylinder piston rod is adjusted to extend so that the limit gap 213 between the connected limit blocks 211 becomes smaller, that is, the contact between the flat tube and the fin is made tighter. Then the movable plate 52 moves to the side of the top plate, close to the flat tube, and presses the flat tube and the fin tightly.

[0071] The drive assembly 4 then drives the moving block 30 away from the platen 11, causing the stop block 211 to separate from the flat tube. The piston rod of the articulated cylinder then extends, pushing the abutment plate 40 to rotate vertically. The drive assembly 4 then drives the moving block 30 toward the platen 11, causing the main plate on the clamping block 401 to engage with the flat tube. Subsequently, under the action of the compression spring 4012, the clamping block 401 remains stationary, while the abutment plate 40 drives the flaring blade 403 to continue moving. The flaring blade 403 engages with the flat tube opening, flaring the flat tube opening and helping to prevent deformation. Finally, the drive assembly 4 drives the moving block 30 away from the platen 11, causing the movable plate 52 to move away from the fixed plate 51. The worker can then remove the finished heater. Repeating the above steps allows for rapid heater assembly.

[0072] While the subsequent assembly operation is being carried out, the flat tubes at the loading assembly 6 have been arranged in the supporting gap 82. After the assembly of the next heater is completed, the loading operation can be carried out immediately. Compared with the original manual loading method, the degree of automation is high, which helps to improve the overall assembly efficiency.

[0073] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
