Description

Technical Field

[0001] The invention relates to an automatic material receiving machine for flat tubes used in radiators. Background Art

[0002] The flat tube in the 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 coolant and air.

[0003] The manufacturing process of the flat tube is to bend both sides of the long sheet toward the middle to form a rectangular tube with a cross section, and then weld the joints on both sides of the long sheet together, and finally cut it into the required length by a cutting machine and push it out from the outlet of the cutting machine at a certain speed. However, when the flat tube pushed out from the outlet of the cutting machine falls onto the platform, the placement angles of the flat tubes are different. The operators are required to align the flat tubes one by one to stack the flat tubes together. Moreover, some of the welds of the flat tubes that fall onto the platform face the downstream direction of the platform, while others face the upstream direction of the platform. It is impossible to ensure that the orientation of the welds on the flat tubes is consistent. Since the flat tubes pushed out from the outlet of the cutting machine also need to be inspected for weld quality, the operators are required to stack each flat tube with the weld facing upwards. This method of collecting flat tubes is very inefficient and labor-intensive. Summary of the invention

[0004] The object of the present invention is to provide an automatic receiving machine for flat tubes for radiators, so as to solve at least one of the above-mentioned technical problems.

[0005] According to one aspect of the present invention, there is provided an automatic receiving machine for flat tubes for radiators, comprising:

[0006] Horizontal conveyor belt;

[0007] A first limiting plate, which is disposed above the horizontal conveyor belt, and a first gap is left between the bottom of the first limiting plate and the horizontal conveyor belt; and

[0008] The second limiting plate is arranged above the horizontal conveyor belt and located in the downstream direction of the first limiting plate. The first limiting plate and the second limiting plate are both arranged obliquely and have the same inclination direction. 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 for the radiator.

[0009] The automatic material receiving machine of the present invention aligns the end of the area between the first limiting plate and the second limiting plate with the exit position of the cutting machine, and the flat tube pushed out from the exit of the cutting machine falls between the first limiting plate and the second limiting plate. Since the first limiting plate and the second limiting plate are both arranged obliquely and in the same direction of inclination, the flat tube dropped between the first limiting plate and the second limiting plate will uniformly tilt toward the downstream direction of the horizontal conveyor belt, and the welds on the tops of the flat tubes will uniformly face the downstream direction of the horizontal conveyor belt. Since the spacing 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, under the conveying action of the horizontal conveyor belt, the tilted flat tube will be conveyed to the downstream through the second gap. Since the cutting machine continuously pushes out the flat tubes, under the continuous conveying of the horizontal conveyor belt, the flat tube pushed out later will obliquely lean against the flat tube pushed out earlier And the weld on each flat tube is facing the downstream direction of the horizontal conveyor belt, except for the first flat tube, the welds on the flat tubes pushed out later are facing obliquely upward in the downstream direction of the horizontal conveyor belt. The cutting machine pauses after working for a period of time. The operator only needs to align the ends of the flat tubes with a baffle, and then push the outermost sides of several flat tubes toward the middle to complete the automatic stacking of the flat tubes. Moreover, the weld of each flat tube after stacking is facing upward, which provides great convenience for the subsequent inspection of the weld quality. The existence of the first gap and the second gap prevents the first limit plate and the second limit plate from interfering with the transportation of the horizontal conveyor belt. The automatic material receiving machine of the present invention can stack the flat tubes continuously pushed out by the cutting machine very quickly, and can ensure that the weld of each flat tube is facing upward, which can effectively improve the production efficiency of the flat tubes.

[0010] Furthermore, the first limit plate and the second limit plate are both inclined toward the downstream direction of the horizontal conveyor belt, and the angle between the first limit plate and the horizontal conveyor belt is greater than the angle between the second limit plate and the horizontal conveyor belt.

[0011] Therefore, the flat tubes that fall between the first limit plate and the second limit plate will all tilt toward the downstream direction of the horizontal conveyor belt. Since the inclination of the second limit plate is greater than that of the first limit plate, when the flat tubes pushed out from the outlet of the cutting machine fall onto the second limit plate, the flat tubes will slide along the second limit plate to the root position of the first limit plate, ensuring that the flat tubes can be transported to the downstream through the second gap and preventing the bottom of the flat tubes from being on the horizontal conveyor belt and the top from being against the second limit plate to block the second gap.

[0012] Furthermore, the second gap is smaller than the width of the flat tube for the radiator.

[0013] Therefore, the longitudinal height of the flat tubes tilted toward the downstream direction can just pass through the second gap. If the flat tubes between the first limiting plate and the second limiting plate are stacked in the longitudinal direction, the bottom of the second limiting plate can block the excess flat tubes in the longitudinal direction to ensure that the flat tubes transported to the downstream direction have only one layer in the longitudinal direction.

[0014] Furthermore, it also includes a gap adjustment mechanism, which can adjust the distance between the bottom of the second limiting plate and the bottom of the first limiting plate.

[0015] Therefore, according to the size of the flat tube, the distance between the bottom of the second limit plate and the bottom of the first limit plate can be adjusted by the gap adjustment mechanism. When the width of the flat tube is larger, the distance between the bottom of the second limit plate and the bottom of the first limit plate is increased by the gap adjustment mechanism. When the width of the flat tube is smaller, the distance between the bottom of the second limit plate and the bottom of the first limit plate is reduced by the gap adjustment mechanism, thereby improving versatility.

[0016] Furthermore, the gap adjustment mechanism includes a bracket, a track, a base and an adjusting screw. The bracket is arranged above the horizontal conveyor belt, the upper end surface of the bracket is arranged obliquely and parallel to the second limit plate, the track and the base are both arranged on the upper end surface of the bracket, the adjusting screw is rotated in the base, the end of the adjusting screw is arranged on the second limit plate, and the second limit plate is arranged on the track and can slide along the track.

[0017] Therefore, when it is necessary to adjust the distance between the bottom of the second limit plate and the bottom of the first limit plate, the adjusting screw is screwed. The adjusting screw can drive the second limit plate to move along the track so that the bottom of the second limit plate is close to or away from the bottom of the first limit plate. The existence of the track can ensure that the second limit plate can move smoothly and ensure that the inclination angle of the second limit plate will not change during the movement.

[0018] Furthermore, a bearing portion is provided on the end surface of the second limiting plate away from the first limiting plate, 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.

[0019] Therefore, by turning the adjusting screw, the adjusting screw can drive the connecting block to move, and the connecting block drives the second limit plate to move synchronously through the bearing part. The second limit plate slides along the track through the bearing part to make the bottom of the second limit plate close to or away from the bottom of the first limit plate. The bearing part can increase the distance between the adjusting screw and the second limit plate to prevent interference between the adjusting screw and the second limit plate.

[0020] Furthermore, it also includes a mounting frame, the horizontal conveyor belt is arranged on the mounting frame, the top of the mounting frame is provided with a first limit platform and a second limit platform, the first limit platform and the second limit platform are respectively located on both sides of the horizontal conveyor belt, and the tops of the first limit platform and the second limit platform are both higher than the horizontal conveyor belt.

[0021] Therefore, the operator stands on one side of the first limit platform or the second limit platform. After the cutting machine is paused after working for a period of time, the operator only needs to use the horizontal part of a T-shaped baffle to hug the distal ends of several flat tubes, and then pull back to place the proximal ends of several flat tubes against the first limit platform or the second limit platform, so as to align the two ends of several flat tubes, so as to achieve fast and neat stacking of the flat tubes with the welds uniformly facing upwards.

[0022] Furthermore, two sides of the bottom of the first limiting plate are respectively arranged on the first limiting platform and the second limiting platform.

[0023] Therefore, since the tops of the first limit platform and the second limit platform are both higher than the horizontal conveyor belt, a first gap will be formed between the bottom of the first limit plate installed on the first limit platform and the second limit platform and the horizontal conveyor belt, ensuring that the first limit plate will not interfere with the transportation of the horizontal conveyor belt.

[0024] Furthermore, the first limiting plate includes an inclined plate and a horizontal plate that are integrally connected, the angle between the inclined plate and the horizontal plate is an obtuse angle, the two ends of the horizontal plate are respectively arranged on the first limiting platform and the second limiting platform, the inclined plate is inclined toward 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, and 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.

[0025] Therefore, the first limit plate can be firmly installed on the first limit platform and the second limit platform through the horizontal plate, and a first gap is formed between the horizontal plate and the horizontal conveyor belt to ensure that the first limit 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 toward 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 limit plate and the horizontal conveyor belt, when the flat tube pushed out from the outlet of the cutting machine falls onto the second limit plate, the flat tube will slide along the second limit plate to the root position of the inclined plate, ensuring that the flat tube can be conveyed to the downstream through the second gap, preventing the bottom of the flat tube from being located on the horizontal conveyor belt and the top from abutting against the second limit plate to block the second gap. Since the distance between the bottom of the second limit plate and the bottom of the inclined plate is greater than the width of the flat tube, under the conveying action of the horizontal conveyor belt, the tilted flat tube will be conveyed to the downstream through the second gap.

[0026] Furthermore, it also includes a protective top and four supporting legs, the bottoms of two supporting legs are arranged on the first limit platform, and the bottoms of the other two supporting legs are arranged on the second limit platform, the protective top is arranged on the top of the supporting legs, the protective top is located above the first limit plate and the second limit plate, and a lamp component is provided on the side of the protective top.

[0027] Therefore, the protective top can prevent foreign objects from falling into the area between the first limit plate and the second limit plate to affect the operation, and can also achieve safety protection. The light component makes it convenient for operators to work in a dim environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] See also Figure 1 The cross section of the flat tube 300 in the vehicle radiator is rectangular, a welding seam 301 is left on the flat tube 300 along its length direction, and the width of the flat tube 300 is L.

[0039] See also Figures 2 to 7 The automatic receiving machine for flat tubes for radiators comprises 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 a supporting foot 7.

[0040] See also Figure 3 The horizontal conveyor belt 1 is installed on the mounting frame 5, and the top of the mounting frame 5 is formed with a first limit platform 51 and a second limit platform 52. The length direction of the first limit platform 51 and the second limit platform 52 is parallel to the conveying direction of the horizontal conveyor belt 1. The first limit platform 51 and the second limit platform 52 are respectively located on both sides of the horizontal conveyor belt 1, and the tops of the first limit platform 51 and the second limit platform 52 are both higher than the horizontal conveyor belt 1.

[0041] See also Figure 2 and Figure 3 The first limit plate 2 is installed above the horizontal conveyor belt 1. Specifically, refer to Figures 5 to 7The first limiting plate 2 includes an integrally connected inclined plate 201 and a horizontal plate 202, the angle between the inclined plate 201 and the horizontal plate 202 is an obtuse angle, and the two ends of the horizontal plate 202 are respectively fixed on the first limiting platform 51 and the second limiting platform 52, and the inclined plate 201 is inclined toward the downstream direction of the horizontal conveyor belt 1. The first limiting plate 2 can be firmly installed on the first limiting platform 51 and the second limiting platform 52 through the horizontal plate 202. Since the tops of the first limiting platform 51 and the second limiting platform 52 are 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, and a first gap 100 ( Figure 7 As shown), this can ensure that the first limiting plate 2 does not interfere with the transportation of the horizontal conveyor belt 1, and the inclined plate 201 and the horizontal plate 202 arranged at an obtuse angle can ensure that the inclined plate 201 is inclined toward the downstream direction of the horizontal conveyor belt 1.

[0042] See also Figure 2 , Figure 3 and Figure 6 The second limiting plate 3 is installed above the horizontal conveyor belt 1, and the second limiting plate 3 is arranged obliquely. The second limiting plate 3 is located in the downstream direction of the first limiting plate 2. Specifically, refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The 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 respectively fixed on the first limit platform 51 and the second limit platform 52. The bracket 41 is gantry-shaped. The transverse part of the bracket 41 is located above the horizontal conveyor belt 1. The upper end surface of the transverse part of the bracket 41 is arranged obliquely. The upper end surface of the transverse part of the bracket 41 is arranged parallel to the second limit plate 3. The number of the tracks 42 is two, and the two tracks 42 are installed on the upper end surface of the transverse part of the bracket 41. The base 43 is mounted on the upper end surface of the horizontal part of the bracket 41, the base 43 is located between the two tracks 42, the adjusting screw 44 is rotated in the base 43, and the end surface of the second limiting plate 3 away from the first limiting plate 2 is installed (such as integrally connected, welded or screwed) with a bearing portion 31, and a connecting block 32 is fixed on the bearing portion 31. The end of the adjusting screw 44 is fixed on the connecting block 32, and the bearing portion 31 is placed on the two tracks 42, and the bearing portion 31 can slide along the two tracks 42, see Figure 2When it is necessary to adjust the distance between the bottom of the second limit plate 3 and the bottom of the first limit plate 2, the adjusting screw 44 is screwed, and the adjusting screw 44 drives the connecting block 32 to move. The connecting block 32 drives the second limit plate 3 to move synchronously through the bearing portion 31, and the second limit plate 3 slides along the track 42 through the bearing portion 31 to make the bottom of the second limit plate 3 close to or away from the bottom of the first limit plate 2. The bearing portion 31 can increase the distance between the adjusting screw 44 and the second limit plate 2 to prevent the adjusting screw 44 from interfering with the second limit plate 3. The existence of the track 42 can ensure that the second limit plate 3 can move smoothly and ensure that the inclination angle of the second limit 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 limit plate 3 and the bottom of the first limit plate 2 can be adjusted by screwing the adjusting screw 44. When the width of the flat tube ( Figure 1 When L) 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 screwing 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 reversely screwing the adjusting screw 44, thereby improving the versatility of the automatic material receiving machine of the present invention.

[0043] See also Figure 2 , Figure 3 , Figure 6 and Figure 7 The second limit plate 3 and the first limit plate 2 are inclined in the same direction, and the inclined plates 201 of the second limit plate 3 and the first limit plate 2 are inclined toward the downstream direction of the horizontal conveyor belt 1. A second gap 200 is left between the bottom of the second limit plate 3 and the horizontal conveyor belt 1, and the height of the second gap 200 is L1 ( Figure 7 As shown), the height L1 of the second gap 200 is smaller than the width of the flat tube ( Figure 1 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 radiator flat tube ( Figure 1The flat tubes dropped between the first limiting plate 2 and the second limiting plate 3 will all fall toward the downstream direction of the horizontal conveyor belt 1. Since the inclination of the second limiting plate 3 is greater than the inclination of the inclined plate 201 of the first limiting plate 2, when the flat tubes pushed out from the outlet of the cutting machine fall onto the second limiting plate 3, the flat tubes will slide along the second limiting plate 3 to the root position of the inclined plate 201 of the first limiting plate 1, ensuring that the flat tubes can be transported to the downstream through the second gap 200, preventing the bottom of the flat tubes from being located on the horizontal conveyor belt 1 and the top from being against the second limiting plate 3 to block the second gap 200. The spacing L2 between the bottom of the first limiting plate 2 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 transported 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 toward the downstream direction can just pass through the second gap 200 in the longitudinal direction. 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 redundant flat tubes in the longitudinal direction to ensure that the flat tubes transported to the downstream direction have only one layer in the longitudinal direction.

[0044] See also Figure 2 and Figure 3 There are four supporting feet 7, the bottoms of two supporting feet 7 are fixed (such as integrally formed) on the first limiting platform 51, and the bottoms of the other two supporting feet 7 are fixed (such as integrally formed) on the second limiting platform 52. The protective top 6 is fixed (such as integrally formed) on the tops of the four supporting feet 7. The protective top 6 is located above the first limiting plate 2 and the second limiting plate 3. A lamp 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 to affect the operation, and can also achieve safety protection. The lamp component 61 is convenient for operators to work in a dim environment.

[0045] In other embodiments, height-adjustable adjustment feet can be installed at the bottom of the four legs of the mounting frame 5. In this way, the overall height of the mounting frame 5 can be adjusted so that the end of the area between the first limit plate 2 and the second limit plate 3 can be aligned with the outlet position of the cutting machine, ensuring that the flat tube pushed out of the outlet of the cutting machine can fall between the first limit plate 2 and the second limit plate 3. In addition, the mounting frame 5 can also be adjusted by the adjustment feet in places with uneven ground to ensure that the mounting frame 5 is placed stably and horizontally on the ground.

[0046] See also Figures 1 to 7The automatic material receiving machine of the present invention aligns the end of the area between the first limiting plate 2 and the second limiting plate 3 with the outlet position of the cutting machine, and the flat tube pushed out from the outlet 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 outlet of the cutting machine falls on the second limiting plate 3, the flat tube will slide 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 obliquely and both face the downstream of the horizontal conveyor belt 1 The flat tubes falling between the first limiting plate 2 and the second limiting plate 3 will be tilted toward the downstream direction of the horizontal conveyor belt 1, and the welds on the tops of the flat tubes will be uniformly oriented toward the downstream direction 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 tubes, under the conveying action of the horizontal conveyor belt 1, the tilted flat tubes will be conveyed to the downstream through the second gap 200. Since the cutting machine continuously pushes out the flat tubes, under the continuous conveying of the horizontal conveyor belt 1, the flat tubes pushed out later The tube will lean obliquely against the flat tube pushed out in front and the weld on each flat tube will face the downstream direction of the horizontal conveyor belt 1. Except for the first flat tube at the beginning, the welds on the flat tubes pushed out later will face obliquely upward in the downstream direction of the horizontal conveyor belt 1. The operator stands on one side of the first limit platform or the second limit platform. After the cutting machine is suspended for a period of time, the operator only needs to use the transverse part of a T-shaped baffle to hug the ends of the distal ends of the several flat tubes, and then pull back to make the proximal ends of the several flat tubes against the first limit platform 51 or the second limit platform 52, so as to align the two ends of the several flat tubes, and then push the outermost two sides of the several flat tubes toward the middle to complete the automatic stacking of the flat tubes, and the weld of each flat tube after stacking will face upward, which provides great convenience for the subsequent inspection of the weld quality, and realizes the rapid and neat stacking of the flat tubes with the welds uniformly facing upward. The automatic material receiving machine of the present invention can stack the flat tubes continuously pushed out by the cutting machine very quickly, and can ensure that the weld of each flat tube faces upward, which can effectively improve the production efficiency of the flat tubes.

[0047] See also 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 screwed, the adjusting screw 44 drives the connecting block 32 to move, and the connecting block 32 drives the second limiting plate 3 to move synchronously through the bearing portion 31, and the second limiting plate 3 slides along the track 42 along the C direction to make the bottom of the second limiting plate 3 away from the bottom of the inclined plate 201 of the first limiting plate 2. When it is necessary to reduce 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 screwed in the opposite direction, the adjusting screw 44 drives the connecting block 32 to move, and the connecting block 32 drives the second limiting plate 3 to move synchronously through the bearing portion 31, and the second limiting plate 3 Slide along the track 42 in the opposite direction of direction C to make the bottom of the second limit plate 3 close to the bottom of the inclined plate 201 of the first limit plate 2. In this way, according to the size of the flat tube, the distance between the bottom of the second limit plate 3 and the bottom of the inclined plate 201 of the first limit plate 2 can be adjusted by screwing the adjusting screw 44. When the width of the flat tube is large, the distance between the bottom of the second limit plate 3 and the bottom of the inclined plate 201 of the first limit plate 2 is increased by screwing the adjusting screw 44. When the width of the flat tube is small, the distance between the bottom of the second limit plate 3 and the bottom of the inclined plate 201 of the first limit plate 2 is reduced by reversely screwing the adjusting screw 44, thereby improving the versatility of the automatic material receiving machine of the present invention.

[0048] The above are only some embodiments of the present invention, which are intended to illustrate the technical means of the present invention, but not to limit the technical scope of the present invention. Those skilled in the art can make obvious improvements to the present invention in combination with existing common knowledge, which all fall within the protection scope of the present invention.
