Description

Technical Field

[0001] The present invention relates to the technical field of radiator production equipment, in particular to automatic tube-fin arrangement equipment. Background Art

[0002] Radiators are commonly used in automotive cooling systems. Radiators are usually square in shape and consist of several parts, including a water chamber (water inlet chamber / water outlet chamber), a radiator core (fins and heat pipes arranged alternately with each other), a main board, and side panels. During assembly, the radiator core must be arranged first, that is, the fins and heat pipes are arranged alternately with each other.

[0003] The existing radiator assembly process of heat pipe feeding is generally done by manually stacking the heat pipes, and then using some automated equipment to transport and position the flat tubes and fins using a conveyor belt or a robot. This has the following technical defects:

[0004] (1) Manual loading is inefficient and has poor precision. Manual placement of heat pipes is prone to misalignment, which affects the quality of subsequent assembly. In addition, the labor intensity is high, and production efficiency is limited by the worker's operating speed.

[0005] (2) Existing automated equipment lacks stability. For example, if a robot is used to grab the pipe directly, it can easily cause deformation of the heat pipe and scratches on the pipe surface. In addition, the belt conveyor has no correction function and is simply conveyed. The heat pipes are prone to stacking or offsetting, requiring additional manual intervention.

[0006] (3) Low positioning accuracy: Flat tubes and fins are prone to displacement during transportation, resulting in assembly misalignment and affecting heat dissipation performance. Complex structure: Some equipment uses multiple sets of independent drive mechanisms, which have poor synchronization and high maintenance costs.

[0007] Traditional manual or semi-automatic layout methods have problems such as low efficiency, poor precision, and insufficient consistency, making it difficult to meet the production needs of modern high-efficiency radiators. Summary of the Invention

DETAILED DESCRIPTION

[0054] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0055] Example

[0056] refer to Figure 1 The automatic tube-fin arrangement equipment includes a heat dissipation tube storage device 1, a heat dissipation tube feeding device 2, a fin conveying device 3 and a tube-fin arrangement device 4.

[0057] Combined with reference Figure 2-Figure 4 The heat pipe storage device 1 includes two silos arranged opposite to each other. Each silo includes a bracket 11, a spacer 12, a first motor 13 and a transmission assembly. There are two first motors 13, which are respectively arranged at both ends of the bracket 11. The transmission assembly is connected to the first motor 13.

[0058] The transmission assembly includes a rotating shaft 141, a transmission gear 142 and a chain 143; there are two rotating shafts 141, each connected to the first motor 13, and there are at least four transmission gears 142, which are symmetrically connected to the rotating shaft 141; there are at least two chains 143, which are connected to the two transmission gears 142 on the same horizontal plane and surround the outside of the bracket 11.

[0059] There are multiple spacers 12, which are vertically connected to the chain 143 at intervals. The first motor 13 drives the spacers 12 to move through the transmission assembly. The space between two spacers 12 constitutes a heat pipe accommodating space.

[0060] The heat pipe storage device 1 also includes a spacing adjustment component, which includes an adjustment motor (not shown in the figure), a reducer 151, a screw 152, a screw nut 153 and a connecting plate 154. The screw 152 is provided with a first thread segment and a second thread segment in opposite directions. There are two screw nuts 153, which are respectively provided on the first thread segment and the second thread segment. When the screw 152 rotates, the two screw nuts 153 move toward or away from each other; there are two connecting plates 154, which are connected to the screw nut 153 and the bracket 11.

[0061] The spacing adjustment assembly further includes a track 155 provided at the bottom of the bracket 11 . The track 155 is parallel to the screw rod 152 . A track slider 156 adapted to the track 155 is provided at the bottom of the bracket 11 .

[0062] When the distance between the two silos needs to be adjusted, the adjustment motor drives the screw 152 to rotate through the reducer 151. When the screw 152 rotates, the two screw nuts 153 move toward or away from each other, so that the two silos slide on the track 155 to adjust the distance between the two silos.

[0063] During use, the distance between the two silos can be adjusted using the spacing adjustment assembly based on the length of the heat pipes. The heat pipes are then manually placed within the storage spaces formed by the spacers 12 between the two silos. Heat pipes in the silos are removed via the heat pipe feeder 2. When the heat pipes in the silo near the heat pipe feeder 2 are exhausted, the first motor 13 drives the chain 143, moving the spacers 12 with sufficient heat pipes toward the feed end.

[0064] Combined with reference Figure 5-Figure 9 The heat pipe feeding device 2 includes a frame 21 and a suction cup material taking assembly, a vertical drive assembly, a horizontal drive assembly and a feeding assembly provided on the frame 21;

[0065] The suction cup assembly includes a support frame 21, a suction cup frame 222, and multiple suction cups 227. The lower end of the suction cup frame 222 has two spaced suction cup receiving plates 223, and multiple suction cups 227 are spaced apart on the suction cup receiving plates 223. The suction cup frame 222 is connected to the frame 21 through the support frame 21. The suction cups 227 are connected to an external vacuum device.

[0066] The transverse drive assembly is used to drive the suction cup frame 222 to move laterally. Specifically, the transverse drive assembly includes a third motor 241, a second gear 242, a second rack 243, and a second linear guide 244. The third motor 241 is mounted on the support frame 21, and the second gear 242 is driven by the third motor 241. The second rack 243 is mounted on the frame 21 and meshes with the second gear 242. The second linear guide 244 is disposed laterally between the frame 21 and the support frame 21. During operation, the third motor 241 rotates the second gear 242 via a drive wheel and a drive belt. Since the second rack 243 is fixed to the frame 21, the rotation of the second gear 242 drives the entire suction cup retrieving assembly to move laterally along the second linear guide 244, allowing it to move above the heat pipe silo.

[0067] The vertical drive assembly is used to drive the suction cup frame 222 to move up and down. Specifically, the vertical drive assembly includes a second motor 231, a first gear 232, a first rack 233 and a first linear guide 234. The second motor 231 is arranged on the support frame 21, the first gear 232 is connected to the output shaft of the second motor 231, the first rack 233 is vertically arranged on the suction cup frame 222, the first rack 233 is engaged with the first gear 232, and the first linear guide 234 is vertically arranged between the suction cup frame 222 and the support frame 21. When in use, the second motor 231 drives the first gear 232 to rotate. The rotation of the first gear 232 will drive the suction cup frame 222 to descend along the first linear guide 234, so that the suction cup 227 contacts the heat pipe in the silo. After the suction cup 227 (vacuum adsorption) absorbs the heat pipe, the second motor 231 reverses, the suction cup frame 222 rises, and the material is taken out.

[0068] More preferably, the suction cup frame 222 is provided with a connecting plate 224, which is equipped with a stepped shaft 225 for detecting the height position of the heat pipe. The connecting plate 224 is provided with a through hole, through which the small diameter section of the stepped shaft 225 passes, and the large diameter section of the stepped shaft 225 is located above the through hole. The lower end of the stepped shaft 225 is lower than the lower end of the suction cup 227. The number of stepped shafts 225 is equal to the number of suction cups 227 within a suction cup receiving plate 223, and their positions correspond. The connecting plate 224 is also equipped with sensors 226 for detecting the movement of the stepped shafts 225, and the number and position of these sensors 226 correspond to the number and position of the stepped shafts 225.

[0069] When the suction cup frame 222 moves downward to absorb the heat pipe, the stepped shaft 225 first touches the heat pipe, and the stepped shaft 225 will extend upward. When each stepped shaft 225 extends upward, it means that the position and number of the heat pipes in the heat pipe silo are normal. At this time, the sensor 226 for detecting the movement of the stepped shaft 225 senses it, and the suction cup 227 absorbs the heat pipe.

[0070] Then, the suction cup picking assembly moves horizontally to transport the heat dissipation tube to just above the feeding assembly.

[0071] The feeding assembly is located below the suction cup picking assembly, and the feeding assembly includes a feeding correction assembly and a conveyor belt 254. The conveyor belt 254 is located below the feeding correction assembly. The conveyor belt 254 is provided with a ridge 2541 for separating the heat dissipation tubes; the pulley of the conveyor belt 254 is driven by a servo motor.

[0072] The feed correction assembly includes a feed guide 251 and a retractable baffle 252. The feed guide 251 has spaced ribs 2511, the spacing between which corresponds to the width of the ribs 2541. The retractable baffle 252 can be used to prevent the heat dissipation pipes on the feed guide 251 from falling downward. Specifically, the feed guide 251 is provided with a horizontal through-slot. The retractable baffle 252 includes a baffle 252 and a cylinder 253. The baffle 252 is connected to the cylinder 253 and passes through the through-slot. The baffle 252 is provided with spaced teeth 2521, which are staggered with the spaced ribs 2511.

[0073] A presence detection sensor (not shown in the figure) for sensing whether the heat dissipation pipe is in place is provided on the frame 21 below the conveyor belt 254 .

[0074] Initially, baffle 252 (driven by cylinder 253) extends, blocking the heat pipe and preventing it from falling. When the presence detection sensor detects that the heat pipe is above baffle 252, the servo motor adjusts the position of conveyor belt 254 so that the position of ridges 2541 on conveyor belt 254 aligns with the position of the ribs on feed guide 251, ensuring a consistent spacing. At this point, the calibration is complete, and cylinder 253 retracts baffle 252, allowing the heat pipe to fall onto conveyor belt 254 under the action of gravity.

[0075] Combined with reference Figure 10-12 The fin conveying device 3 includes a support frame 31, a movable conveying frame group, a first pulley 32, a second pulley 33, a conveyor belt 34 and a locking mechanism. The movable conveying frame group is arranged on the support frame 31 and can slide relatively. The movable conveying frame group includes a slide rail 351, a slider 352 and a conveying channel 353.

[0076] The first pulley 32 (upper) and the second pulley 33 (lower) are spaced apart from each other, and the conveyor belt 34 passes around the first pulley 32 and the second pulley 33 in an S-shaped arrangement. The first pulley 32 and the second pulley 33 are driven by an external power source (such as a motor) to rotate, thereby achieving continuous movement of the conveyor belt 34.

[0077] There are two sliders 352, spaced apart on the bracket. The slide rails 351 are slidably connected to the sliders 352 and are connected to the second pulley 33 and the transmission channel 353 via a connecting block 354. The transmission channel 353 is connected to the first pulley 32. Specifically, the transmission channel 353 can be connected to the wheel bearing of the first pulley 32 using a connecting member.

[0078] The first pulley 32 is positioned above the second pulley 33. The conveying channel 353 has side ribs and a hollow bottom. The bottom of the conveying channel 353 is located on the conveyor belt 34 above the first pulley 32. The bottom of the conveying channel 353 is open, with side ribs restricting the position of the fins. The bottom is directly supported by the conveyor belt 34 above the first pulley 32. When the conveyor belt 34 moves, it drives the fins placed in the conveying channel 353 forward.

[0079] The slide rail 351 can slide horizontally along the slider 352. When the slide rail 351 moves, it synchronously drives the second pulley 33, the transmission channel 353, and the first pulley 32 to move as a whole. The S-shaped path of the conveyor belt 34 automatically adapts to the change in the distance between the pulleys, thereby changing the effective length of the conveyor belt 34 at the bottom of the transmission channel 353.

[0080] A locking mechanism is located below the slide rail 351 and is used to lock the slide rail 351. The locking mechanism includes a clamping jaw 361 and a clamping jaw driver. The clamping jaw 361 engages with the slide rail 351, and the clamping jaw driver drives the clamping jaw 361 to move vertically. In this embodiment, there are two clamping jaws 361, located on either side of the slide rail 351. The clamping jaw driver utilizes a dual-axis cylinder 362, the piston rod of which is connected to the clamping jaw 361. The shape of the clamping jaw 361 is adapted to the shape of the slot in the slide rail 351.

[0081] When the position of the slide rail 351 needs to be adjusted, the dual-axis cylinder 362 drives the two clamps 361 to move upward synchronously. When the clamps 361 are released, the position of the slide rail 351 can be manually adjusted. When the slide rail 351 is adjusted to the target position, the dual-axis cylinder 362 drives the two clamps 361 to move downward synchronously. The clamps 361 clamp both sides of the slide rail 351 and fix the slide rail 351 through the slot structure to prevent it from shifting during the transmission process.

[0082] Combined with reference Figure 13-16 The tube-fin arrangement device 4 includes two symmetrically arranged transmission comb mechanisms, which include a frame 41, a drive assembly, a transmission wheel set, a transmission belt and a comb belt 45.

[0083] The drive assembly is mounted on the frame 41 and drives the transmission belt via a transmission wheel assembly. Specifically, the transmission belt is a synchronous belt 44 having teeth on its inner side (not shown). The drive assembly includes a fourth motor 421, a third gear 422, and a fourth gear 423. The fourth motor 421 is mounted on the frame 41. The third gear 422 is connected to the output shaft of the fourth motor 421. The fourth gear 423 meshes with the third gear 422 for transmission. The transmission wheel assembly includes a driving synchronous gear 431 and a first driven synchronous gear 432. The driving synchronous gear 431 is coaxially connected to the fourth gear 423.

[0084] The transmission wheel group also includes a second driven synchronous wheel 433. The driving synchronous wheel 431 and the second driven synchronous wheel 433 are arranged at both ends. The tooth top circle diameter of the second driven synchronous wheel 433 is smaller than the tooth top circle diameter of the driving synchronous wheel 431. The first driven synchronous wheel 432 is arranged close to the second driven synchronous wheel 433. The first driven synchronous wheel 432 is the same size as the driving synchronous wheel 431.

[0085] The comb tooth belt 45 is composed of a plurality of comb tooth blocks 451 , which are attached to the outside of the transmission belt. The comb tooth blocks 451 have comb tooth grooves 4511 for accommodating heat dissipation pipes and fins.

[0086] Specifically, the comb block 451 is connected to the synchronous belt 44 by a clamping tooth 46. The clamping tooth 46 includes a connected connecting piece 461 and a threaded sleeve 462. The comb groove 4511 in the middle of the comb block 451 is provided with a countersunk hole 45111, and the synchronous belt 44 corresponding to the countersunk hole 45111 is provided with a through hole. After the threaded sleeve 462 passes through the through hole, it is locked with a bolt 463; the belt teeth at the through hole on the inner side of the synchronous belt 44 need to be flattened to prevent interference from the clamping tooth 46.

[0087] The present invention further includes a sensor 47 for sensing whether the heat dissipation pipe is in place. The sensor 47 is disposed on the frame 41 of one of the transmission comb mechanisms.

[0088] The following is the procedure for using the fin conveyor 3: Start the fourth motor 421. The fourth motor 421 drives the active synchronous wheel 431 through the third gear 422 and the fourth gear 423, which drives the synchronous belt 44 and the comb belt 45 to operate. The comb belts 45, which are symmetrical on both sides, move synchronously. The heat pipes are fed into the comb grooves 4511 of the comb belt 45 at intervals by the heat pipe feeding device 2. The accommodating space of the comb block 451 ensures that the materials are arranged in an orderly manner. When the heat pipe runs close to the fin conveyor 3, the sensor 47 senses that the heat pipe has run into place. The fin conveyor 3 inserts the fin into the comb groove 4511 between the two heat pipes. The comb block 451 is rigidly connected to the synchronous belt 44 through the clamping teeth 46 to ensure the stability of the heat pipe and fins during the conveying process. The comb belt 45 carrying the heat pipe and fins continues to move forward.

[0089] Since the diameter of the second driven synchronous wheel 433 is smaller, the comb-toothed belt 45 forms an expanded distance between the first driven synchronous wheel 432 and the second driven synchronous wheel 433, and the arranged heat dissipation tubes and fins of the comb-toothed belt 45 automatically detach from the comb-toothed belt 45. At this time, the subsequent lifting device will lift up the arranged heat dissipation tubes and fins detached from the comb-toothed belt 45, clamp them and transport them to the assembly station.

[0090] The comb belt 45 continues to run and returns to the starting end without load, waiting for the next cycle.

[0091] The present invention realizes high-precision, high-efficiency and high-stability arrangement of radiator flat tubes and fins, significantly improves product quality and production efficiency, while reducing maintenance and adjustment costs, and is suitable for large-scale automated production needs.

[0092] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
