Description

Technical Field

[0001] This utility model relates to an automatic material receiving machine for flat tubes used in radiators. Background Technology

[0002] The flat tube in a car radiator is one of the core components of the radiator. The flat tube is mainly responsible for transferring heat and promoting heat exchange between the coolant and the air.

[0003] The manufacturing process of flat tubes involves bending both sides of a long sheet of material towards the middle to form a rectangular tube. The two sides of the sheet are then welded together. Finally, the tubes are cut to the required length using a cutting machine and ejected from the machine's exit at a certain speed. However, when the flat tubes fall onto the platform from the machine's exit, their angles vary. Workers need to align the tubes one by one and stack them together. Furthermore, the weld seams of the tubes falling onto the platform can vary, with some facing downstream and others upstream, making it impossible to ensure consistent weld orientation. Since the tubes ejected from the machine's exit also need to undergo weld quality inspection, workers must stack each tube with its weld seam facing upwards. This method of collecting flat tubes is extremely inefficient and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide an automatic material receiving machine for flat tubes used in radiators, in order to solve at least one of the above-mentioned technical problems.

[0005] According to one aspect of the present invention, an automatic take-up machine for flat tubes used in radiators is provided, comprising:

[0006] Horizontal conveyor belt;

[0007] The first limiting plate is located above the horizontal conveyor belt, and a first gap is left between the bottom of the first limiting plate and the horizontal conveyor belt.

[0008] The second limiting plate is positioned above the horizontal conveyor belt and downstream of the first limiting plate. Both the first and second limiting plates are arranged at an angle with the same direction of inclination. A second gap is left between the bottom of the second limiting plate and the horizontal conveyor belt. The distance between the bottom of the second limiting plate and the bottom of the first limiting plate is greater than the width of the flat tube used for the radiator.

[0009] The gap adjustment mechanism can adjust the distance between the bottom of the second limiting plate and the bottom of the first limiting plate.

[0010] This utility model discloses an automatic flat tube receiving machine for radiators. The end of the area between the first and second limiting plates is aligned with the exit position of the cutting machine. The flat tubes pushed out from the cutting machine's exit fall between the first and second limiting plates. Since both the first and second limiting plates are inclined in the same direction, the flat tubes falling between them will uniformly tilt downstream of the horizontal conveyor belt. The weld seams at the top of the flat tubes will uniformly face downstream of the horizontal conveyor belt. Because the distance between the bottom of the second and first limiting plates is greater than the width of the flat tube, the tilted flat tubes will be conveyed downstream through the second gap under the conveying action of the horizontal conveyor belt. As the cutting machine continuously pushes out flat tubes, under the continuous conveying of the horizontal conveyor belt, the later-pushed flat tubes will lean obliquely against the previously pushed flat tubes, and the weld seams on each flat tube will face downstream of the horizontal conveyor belt. Except for the first flat tube, the weld seams on the later-pushed flat tubes all face obliquely upwards towards the downstream direction of the horizontal conveyor belt. After the cutting machine has been operating for a period of time, it pauses. The operator only needs to use a baffle to align the ends of the flat tubes, and then push the outermost two sides of several flat tubes towards the middle to complete the automatic stacking of the flat tubes. Moreover, the weld seam of each flat tube is facing upwards after stacking, which greatly facilitates the subsequent inspection of the weld seam quality. The existence of the first gap and the second gap ensures that the first limit plate and the second limit plate will not interfere with the conveying of the horizontal conveyor belt. In addition, according to the size of the flat tube, the gap adjustment mechanism can adjust the distance between the bottom of the second limit plate and the bottom of the first limit plate. When the width of the flat tube is large, the gap adjustment mechanism increases the distance between the bottom of the second limit plate and the bottom of the first limit plate. When the width of the flat tube is small, the gap adjustment mechanism decreases the distance between the bottom of the second limit plate and the bottom of the first limit plate, thereby improving versatility. The automatic material receiving machine of this utility model can very quickly stack the flat tubes continuously pushed out by the cutting machine together, and can ensure that the weld seam of each flat tube is facing upwards, which can effectively improve the production efficiency of flat tubes.

[0011] Furthermore, both the first limiting plate and the second limiting plate are inclined in the downstream direction of the horizontal conveyor belt, and the angle between the first limiting plate and the horizontal conveyor belt is greater than the angle between the second limiting plate and the horizontal conveyor belt.

[0012] Therefore, the flat tubes that fall between the first and second limiting plates will all tilt downstream of the horizontal conveyor belt. Since the inclination of the second limiting plate is greater than that of the first limiting plate, when the flat tubes pushed out from the cutting machine outlet fall onto the second limiting plate, they will slide down the second limiting plate to the root position of the first limiting plate, ensuring that the flat tubes can be conveyed downstream through the second gap, preventing the bottom of the flat tubes from being on the horizontal conveyor belt and the top from being against the second limiting plate and blocking the second gap.

[0013] Furthermore, the second gap is smaller than the width of the flat tube used for the radiator.

[0014] Therefore, the height of the flat tube tilted downstream is just enough to pass through the second gap. If the flat tubes between the first and second limiting plates are stacked in the longitudinal direction, the bottom of the second limiting plate can block the excess flat tubes in the longitudinal direction, ensuring that there is only one layer of flat tubes transported downstream.

[0015] Furthermore, the gap adjustment mechanism includes a bracket, a track, a base, and an adjusting screw. The bracket is located above the horizontal conveyor belt, and the upper end face of the bracket is arranged at an angle and parallel to the second limiting plate. The track and the base are both located on the upper end face of the bracket. The adjusting screw is screwed into the base, and the end of the adjusting screw is located on the second limiting plate. The second limiting plate is located on the track and can slide along the track.

[0016] Therefore, when it is necessary to adjust the distance between the bottom of the second limiting plate and the bottom of the first limiting plate, turn the adjusting screw. The adjusting screw can drive the second limiting plate to move along the track so that the bottom of the second limiting plate is closer to or further away from the bottom of the first limiting plate. The existence of the track can ensure that the second limiting plate can move smoothly and that the tilt angle of the second limiting plate will not change during the movement.

[0017] Furthermore, a bearing portion is provided on the end face of the second limiting plate away from the first limiting plate, and a connecting block is provided on the bearing portion. The end of the adjusting screw is provided on the connecting block, and the bearing portion is provided on the track and can slide along the track.

[0018] Therefore, by turning the adjusting screw, the adjusting screw can drive the connecting block to move. The connecting block drives the second limiting plate to move synchronously through the bearing part. The second limiting plate slides along the track through the bearing part so that the bottom of the second limiting plate is close to or away from the bottom of the first limiting plate. The bearing part can increase the distance between the adjusting screw and the second limiting plate to prevent the adjusting screw from interfering with the second limiting plate.

[0019] Furthermore, it also includes a mounting frame, on which the horizontal conveyor belt is mounted. The top of the mounting frame is provided with a first limiting platform and a second limiting platform, which are located on both sides of the horizontal conveyor belt. The tops of the first limiting platform and the second limiting platform are both higher than the horizontal conveyor belt.

[0020] Therefore, when the operator stands on one side of the first limiting platform or the second limiting platform, after the cutting machine has been working for a period of time and then pauses, the operator only needs to use the horizontal part of a T-shaped baffle to hold the far end of several flat tubes, and then pull back to bring the near end of several flat tubes against the first or second limiting platform. This will align both ends of several flat tubes, enabling the flat tubes to be stacked quickly and neatly with the weld seams facing upwards.

[0021] Furthermore, the bottom sides of the first limiting plate are respectively provided on the first limiting platform and the second limiting platform.

[0022] Therefore, since the tops of both the first and second limiting platforms are higher than the horizontal conveyor belt, a first gap will be formed between the bottom of the first limiting plate installed on the first and second limiting platforms and the horizontal conveyor belt, ensuring that the first limiting plate will not interfere with the conveying of the horizontal conveyor belt.

[0023] Furthermore, the first limiting plate includes an integrally connected inclined plate and a horizontal plate, with an obtuse angle between the inclined plate and the horizontal plate. The two ends of the horizontal plate are respectively set on the first limiting platform and the second limiting platform. The inclined plate is inclined in the downstream direction of the horizontal conveyor belt. The angle between the inclined plate and the horizontal conveyor belt is greater than the angle between the second limiting plate and the horizontal conveyor belt. The gap between the horizontal plate and the horizontal conveyor belt forms a first gap. The distance between the bottom of the second limiting plate and the bottom of the inclined plate is greater than the width of the flat tube for the radiator.

[0024] Therefore, the first limiting plate can be stably installed on the first limiting platform and the second limiting platform through the horizontal plate. A first gap is formed between the horizontal plate and the horizontal conveyor belt to ensure that the first limiting plate will not interfere with the conveying of the horizontal conveyor belt. The inclined plate and the horizontal plate arranged at an obtuse angle can ensure that the inclined plate is inclined in the downstream direction of the horizontal conveyor belt. Since the angle between the inclined plate and the horizontal conveyor belt is greater than the angle between the second limiting plate and the horizontal conveyor belt, when the flat tube pushed out from the cutting machine outlet falls onto the second limiting plate, the flat tube will slide down the second limiting plate to the root position of the inclined plate, ensuring that the flat tube can be conveyed downstream through the second gap. This prevents the bottom of the flat tube from being on the horizontal conveyor belt and the top from abutting against the second limiting plate to block the second gap. Since the distance between the bottom of the second limiting plate and the bottom of the inclined plate is greater than the width of the flat tube, the tilted flat tube will be conveyed downstream through the second gap under the conveying action of the horizontal conveyor belt.

[0025] Furthermore, it also includes a protective top and four support legs. The bottom of two support legs is located on the first limiting platform, and the bottom of the other two support legs is located on the second limiting platform. The protective top is located on the top of the support legs and is above the first and second limiting plates. A lamp component is provided on the side of the protective top.

[0026] Therefore, the protective top can prevent foreign objects from falling into the area between the first and second limit plates, affecting the operation, and can also achieve safety protection. The lighting components make it convenient for workers to work in dim environments. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0037] See Figure 1 The flat tube 300 in the automotive radiator has a rectangular cross-section and a weld seam 301 along its length. The width of the flat tube 300 is L.

[0038] See Figures 2 to 7 An automatic material receiving machine for flat tubes used in radiators includes a horizontal conveyor belt 1, a first limiting plate 2, a second limiting plate 3, a gap adjustment mechanism, a mounting frame 5, a protective top 6, and support feet 7.

[0039] See Figure 3 The horizontal conveyor belt 1 is installed on the mounting frame 5. The top of the mounting frame 5 is formed with a first limiting platform 51 and a second limiting platform 52. The length direction of the first limiting platform 51 and the second limiting platform 52 is parallel to the conveying direction of the horizontal conveyor belt 1. The first limiting platform 51 and the second limiting platform 52 are located on both sides of the horizontal conveyor belt 1, and the top of the first limiting platform 51 and the second limiting platform 52 are both higher than the horizontal conveyor belt 1.

[0040] See Figure 2 and Figure 3 The first limiting plate 2 is installed above the horizontal conveyor belt 1. Specifically, see [link to relevant documentation]. Figures 5 to 7 The first limiting plate 2 includes an integrally connected inclined plate 201 and a horizontal plate 202, with an obtuse angle between them. The two ends of the horizontal plate 202 are respectively fixed to the first limiting platform 51 and the second limiting platform 52. The inclined plate 201 is inclined downstream of the horizontal conveyor belt 1. The first limiting plate 2 can be stably installed on the first limiting platform 51 and the second limiting platform 52 via the horizontal plate 202. Since the tops of the first limiting platform 51 and the second limiting platform 52 are both higher than the horizontal conveyor belt 1, a first gap 100 is left between the bottom of the first limiting plate 2 and the horizontal conveyor belt 1. A first gap 100 is also formed between the horizontal plate 202 and the horizontal conveyor belt 1. Figure 7 As shown), this ensures that the first limiting plate 2 will not interfere with the conveying of the horizontal conveyor belt 1. The inclined plate 201 and the horizontal plate 202 arranged at an obtuse angle can ensure that the inclined plate 201 is inclined in the downstream direction of the horizontal conveyor belt 1.

[0041] See Figure 2 , Figure 3 and Figure 6 The second limiting plate 3 is installed above the horizontal conveyor belt 1. The second limiting plate 3 is arranged at an angle and is located downstream of the first limiting plate 2. Specifically, refer to [reference needed]. Figure 2 , Figure 3 , Figure 5 and Figure 6The gap adjustment mechanism includes a bracket 41, a track 42, a base 43, and an adjusting screw 44. The two ends of the bracket 41 are fixed to the first limiting platform 51 and the second limiting platform 52, respectively. The bracket 41 is gantry-shaped, with its transverse portion positioned above the horizontal conveyor belt 1. The upper surface of the transverse portion of the bracket 41 is arranged at an angle, parallel to the second limiting plate 3. Two tracks 42 are installed on the upper surface of the transverse portion of the bracket 41. The base 43 is mounted on the upper end face of the transverse portion of the bracket 41. The base 43 is located between two rails 42. The adjusting screw 44 is screwed into the base 43. A bearing part 31 is installed (e.g., integrally connected, welded, or fixed with screws) on the end face of the second limiting plate 3 away from the first limiting plate 2. A connecting block 32 is fixed on the bearing part 31. The end of the adjusting screw 44 is fixed to the connecting block 32. The bearing part 31 rests against the two rails 42 and can slide along the two rails 42. (See reference...) Figure 2 When it is necessary to adjust the distance between the bottom of the second limiting plate 3 and the bottom of the first limiting plate 2, the adjusting screw 44 is turned. The adjusting screw 44 drives the connecting block 32 to move. The connecting block 32 drives the second limiting plate 3 to move synchronously through the bearing part 31. The second limiting plate 3 slides along the track 42 through the bearing part 31 so that the bottom of the second limiting plate 3 is closer to or farther away from the bottom of the first limiting plate 2. The bearing part 31 can increase the distance between the adjusting screw 44 and the second limiting plate 2 to prevent interference between the adjusting screw 44 and the second limiting plate 3. The existence of the track 42 can ensure that the second limiting plate 3 can move smoothly and that the tilt angle of the second limiting plate 3 will not change during the movement. In this way, according to the size of the flat tube, the distance between the bottom of the second limiting plate 3 and the bottom of the first limiting plate 2 can be adjusted by turning the adjusting screw 44. When the width of the flat tube ( Figure 1 When the L in the middle is large, the distance between the bottom of the second limiting plate 3 and the bottom of the first limiting plate 2 is increased by turning the adjusting screw 44. When the width of the flat tube ( Figure 1 When L is small, the distance between the bottom of the second limiting plate 3 and the bottom of the first limiting plate 2 can be reduced by turning the adjusting screw 44 in the opposite direction, thereby improving the versatility of the automatic receiving machine of this utility model.

[0042] See Figure 2 , Figure 3 , Figure 6 and Figure 7 The second limiting plate 3 and the first limiting plate 2 are inclined in the same direction. The inclined plates 201 of both the second limiting plate 3 and the first limiting plate 2 are inclined downstream of the horizontal conveyor belt 1. A second gap 200 is left between the bottom of the second limiting plate 3 and the horizontal conveyor belt 1. The height of the second gap 200 is L1. Figure 7 As shown), the height L1 of the second gap 200 is less than the width of the flat tube. Figure 1In the figure, the angle between the inclined plate 201 of the first limiting plate 2 and the horizontal conveyor belt 1 is greater than the angle between the second limiting plate 3 and the horizontal conveyor belt 1, and the distance between the bottom of the second limiting plate 3 and the bottom of the inclined plate 201 of the first limiting plate 2 is L2. Figure 4 As shown), L2 is greater than the width of the flat tube used for the radiator. Figure 1 The flat tube falling between the first limiting plate 2 and the second limiting plate 3 will tilt uniformly towards the downstream direction of the horizontal conveyor belt 1. Since the inclination of the second limiting plate 3 is greater than that of the inclined plate 201 of the first limiting plate 2, when the flat tube pushed out from the cutting machine outlet falls onto the second limiting plate 3, it will slide down along the second limiting plate 3 to the root position of the inclined plate 201 of the first limiting plate 1. This ensures that the flat tube can be conveyed downstream through the second gap 200, preventing the bottom of the flat tube from being on the horizontal conveyor belt 1 and the top from abutting against the second limiting plate 3 to block the second gap 200. The distance L2 between the bottom of 3 and the bottom of the inclined plate 201 of the first limiting plate 1 is greater than the width of the flat tube. In this way, under the conveying action of the horizontal conveyor belt 1, the tilted flat tube will be conveyed to the downstream through the second gap 200. In addition, since the height L1 of the second gap 200 is less than the width of the flat tube, the height of the flat tube tilted downstream in the longitudinal direction is just enough to pass through the second gap 200. If the flat tubes between the first limiting plate 2 and the second limiting plate 3 are stacked in the longitudinal direction, the bottom of the second limiting plate 3 can block the excess flat tubes in the longitudinal direction, ensuring that the flat tubes conveyed to the downstream direction are only one layer in the longitudinal direction.

[0043] See Figure 2 and Figure 3 There are four support legs 7. The bottoms of two support legs 7 are fixed (e.g., integrally formed) on the first limiting platform 51, and the bottoms of the other two support legs 7 are fixed (e.g., integrally formed) on the second limiting platform 52. The protective top 6 is fixed (e.g., integrally formed) on the top of the four support legs 7. The protective top 6 is located above the first limiting plate 2 and the second limiting plate 3. A light component 61 is installed on the side of the protective top 6 facing the downstream direction of the horizontal conveyor belt 1. The protective top 6 can prevent foreign objects from falling into the area between the first limiting plate 2 and the second limiting plate 3 and affecting the operation. It can also achieve safety protection. The light component 61 makes it convenient for operators to work in a dim environment.

[0044] See Figures 1 to 7The automatic receiving machine of this utility model aligns the end of the area between the first limiting plate 2 and the second limiting plate 3 with the exit position of the cutting machine. The flat tube pushed out from the exit of the cutting machine falls between the first limiting plate 2 and the second limiting plate 3. When the flat tube pushed out from the exit of the cutting machine falls onto the second limiting plate 3, the flat tube will slide down along the second limiting plate 3 to the root position of the inclined plate 201 of the first limiting plate 1. Since the inclined plate 201 of the first limiting plate 2 and the second limiting plate 3 are both arranged at an inclination and both are downstream of the horizontal conveyor belt 1, The flat tubes, tilted in direction, fall between the first limiting plate 2 and the second limiting plate 3 and will uniformly tilt downstream of the horizontal conveyor belt 1. The weld seams at the top of the flat tubes will also uniformly face downstream of the horizontal conveyor belt 1. Since the distance between the bottom of the second limiting plate 3 and the bottom of the first limiting plate 2 is greater than the width of the flat tube, the tilted flat tubes will be conveyed downstream through the second gap 200 under the conveying action of the horizontal conveyor belt 1. As the cutting machine continuously pushes out the flat tubes, under the continuous conveying of the horizontal conveyor belt 1, the later-pushed flat tubes will... The tubes will lean obliquely against the forward-pushed flat tubes, and the weld seams on each flat tube will face downstream of the horizontal conveyor belt 1. Except for the first flat tube, the weld seams on the subsequent flat tubes will face obliquely upwards downstream of the horizontal conveyor belt 1. The operator stands on one side of the first limiting platform or the second limiting platform. After the cutting machine has been working for a period of time and then paused, the operator only needs to use the horizontal part of a T-shaped baffle to hold the far ends of several flat tubes, and then pull back to bring the near ends of several flat tubes against the first limiting platform 51 or the second limiting platform 52. On the two limiting platforms 52, the two ends of several flat tubes can be aligned, and then the outermost two sides of several flat tubes can be pushed towards the middle to complete the automatic stacking of flat tubes. Moreover, the weld seam of each flat tube after stacking faces upward, which provides great convenience for subsequent weld quality inspection. It realizes the rapid and neat stacking of flat tubes with the weld seam facing upward. The automatic material receiving machine of this utility model can very quickly stack the flat tubes continuously pushed out by the cutting machine together, and can ensure that the weld seam of each flat tube faces upward, which can effectively improve the production efficiency of flat tubes.

[0045] See Figure 8When it is necessary to increase the distance between the bottom of the second limiting plate 3 and the bottom of the inclined plate 201 of the first limiting plate 2, the adjusting screw 44 is turned. The adjusting screw 44 drives the connecting block 32 to move. The connecting block 32 drives the second limiting plate 3 to move synchronously through the bearing part 31. The second limiting plate 3 slides along the track 42 in the C direction so that the bottom of the second limiting plate 3 is away from the bottom of the inclined plate 201 of the first limiting plate 2. When it is necessary to decrease the distance between the bottom of the second limiting plate 3 and the bottom of the inclined plate 201 of the first limiting plate 2, the adjusting screw 44 is turned in the opposite direction. The adjusting screw 44 drives the connecting block 32 to move. The connecting block 32 drives the second limiting plate 3 to move synchronously through the bearing part 31. The second limiting plate 3 slides along the track 42 in the C direction so that the bottom of the second limiting plate 3 is away from the bottom of the inclined plate 201 of the first limiting plate 2. The second limiting plate 3 slides along the track 42 in the opposite direction of direction C so that the bottom of the second limiting plate 3 is close to the bottom of the inclined plate 201 of the first limiting plate 2. In this way, the distance between the bottom of the second limiting plate 3 and the bottom of the inclined plate 201 of the first limiting plate 2 can be adjusted by turning the adjusting screw 44 according to the size of the flat tube. When the width of the flat tube is large, the distance between the bottom of the second limiting plate 3 and the bottom of the inclined plate 201 of the first limiting plate 2 can be increased by turning the adjusting screw 44. When the width of the flat tube is small, the distance between the bottom of the second limiting plate 3 and the bottom of the inclined plate 201 of the first limiting plate 2 can be decreased by turning the adjusting screw 44 in the opposite direction. This can improve the versatility of the automatic receiving machine of this utility model.

[0046] The above descriptions are merely some embodiments of this utility model, intended to illustrate the technical means of this utility model, and are not intended to limit the technical scope of this utility model. Any obvious improvements made to this utility model by those skilled in the art in conjunction with existing common knowledge fall within the protection scope of this utility model.
