Description

Technical Field

[0001] This invention relates to the field of heat exchanger piping assembly and testing technology, specifically to an automatic assembly, adjustment and testing device for heat exchanger piping. Background Technology

[0002] As a core piece of equipment in energy conversion, industrial cooling and other fields, the structural integrity and sealing performance of heat exchangers directly determine the operating efficiency and safety of the equipment. Pipe assembly is a key process in the manufacturing of heat exchangers. In particular, when fixing and connecting the cylindrical straight tubes and U-shaped coils, it is necessary to ensure the precise docking and reliable sealing between the pipes and the tube sheet end caps. At present, the assembly and testing of this process are often carried out separately, which has problems such as low efficiency, insufficient automation and single testing methods, making it difficult to meet the needs of modern high-efficiency, high-quality intelligent production.

[0003] A prior art patent (Chinese Patent Publication No. CN119666539B) discloses a tube-and-shell heat exchanger pipe strength testing device, which includes a base, a fixed feeding mechanism, a water pressure conveying connection mechanism, and a width adjustment mechanism. This invention uses the fixed feeding mechanism to support, convey, and fix the U-shaped tube at its ends, allowing the two ends of the U-shaped tube to move horizontally and align with the connector tube in the water pressure conveying connection mechanism. This improves the accuracy of the connection between the U-shaped tube and the connector tube. Then, a sealing and pressing assembly is used to cover and seal the connection between the U-shaped tube and the connector tube, which not only improves the sealing effect at the connection and prevents leakage, but also achieves axial limiting of the arc-shaped clamp, greatly improving the sealing effect and connection stability of the U-shaped tube and the connector tube during water pressure strength testing.

[0004] The aforementioned devices and existing heat exchanger pipe testing devices mostly focus on single strength testing or sealing testing, and cannot simultaneously complete the precision assembly of the pipes during the testing process. Assembly and testing must be carried out step by step, which not only increases the process flow time and equipment investment, but may also lead to positioning errors caused by multiple clamping, affecting the final product quality. The testing methods are limited and unreliable, the testing forms are usually relatively simple, and the reliability and accuracy of the test results need to be improved. Automation and continuity are poor. Existing devices lack efficient automatic feeding, positioning and unloading systems, making it difficult to achieve continuous and stable automatic feeding and assembly of columnar tubes and U-shaped tubes. Assembly testing requires continuous manual intervention, resulting in low production assembly efficiency. Therefore, a device is needed to solve the above problems. Summary of the Invention

[0015] The beneficial effects of this invention are:

[0016] I. This invention enables the integrated and simultaneous assembly and testing, which greatly improves the efficiency and quality of assembly and testing. This device can sequentially complete docking and fixing, sealing test and preliminary strength assessment in the same workstation and in the same clamping and positioning, eliminating the time spent waiting between processes and repeated positioning, thus improving efficiency, avoiding the cumulative positioning error caused by multiple transfers and clamping, and ensuring the consistency and stability of assembly accuracy.

[0017] II. This invention can achieve multiple detections. By injecting colored liquid into the tube and pressurizing it, the presence or absence of staining on the white detection cloth below can be used to quickly and intuitively determine the leakage at the assembly connection point. By detecting specific tracer gases through a gas detection sensor, sensitive and automated detection of microscopic leaks can be achieved, improving detection accuracy. Dual detection verifies each other, balancing detection speed and accuracy, and ensuring the precision of the sealing judgment. By using the cooperation of a second laser ranging sensor and a detection plate, non-contact verification of whether the columnar tube is placed in place can be achieved, thereby indirectly ensuring the automatic alignment of bolt holes on the flanges at both ends, creating conditions for subsequent automated fastening. A pressure sensor monitors the extrusion force when fixing the tube fittings in real time, ensuring that the clamping force is both firm and reliable without damaging the tube. A first laser ranging sensor monitors the displacement of the internal pushing mechanism, achieving precise control of the assembly process. The first and second fixed auxiliary detection units not only serve to fix and limit the tube but also apply specified extrusion force to the assembled columnar tube and U-shaped serpentine tube, achieving tube strength testing.

[0018] III. During the assembly and testing of this device, continuous automatic feeding can be achieved. Each telescopic pallet is inserted into the gaps between the evenly stacked columnar tubes and U-shaped coils, ensuring that the bottoms of the columnar tubes and U-shaped coils inside the first and second storage frames are independently supported. This facilitates the addition of columnar tubes and U-shaped coils into the first and second storage frames. Furthermore, after the second electric push rod moves the horizontal plate and telescopic pallets outward to remove support from the bottoms of the columnar tubes and U-shaped coils, the neatly stacked columnar tubes or U-shaped coils can be discharged one by one from the first or second storage frame. The overall height of the feeding unit can be controlled by the first electric push rod. The distance between the bottom of the feeding body and the assembly and testing body is adjusted, and the position of the second assembly limiting frame is adjusted so that the falling columnar tubes and U-shaped snake tubes can accurately enter the interior of the second assembly limiting groove and the first assembly limiting groove, which can realize continuous, accurate and automatic material replenishment. The moving first positioning plate can squeeze one end of the columnar tubes that are evenly stacked in the first storage frame, so that the columnar tubes stacked in the first storage frame are neatly placed inside the first storage frame. Similarly, through the squeezing and adjustment of the second positioning plate, the U-shaped snake tubes are neatly placed inside the second storage frame. Thus, the columnar tubes and U-shaped snake tubes neatly stacked in the first and second storage frames can accurately achieve the same landing point, so that the position is accurate when automatically adding and replenishing columnar tubes and U-shaped snake tubes.

[0032] The invention will be further described below with reference to the accompanying drawings.

[0033] like Figure 1 , 5As shown in Figure 6, an automatic assembly, adjustment, and testing device for heat exchanger pipes according to the present invention includes a support bracket 1, a rotating gear disk 2, a motor 3, a drive gear 4, a fixed support base 5, an assembly and testing body 6, a first electric push rod 7, and a feeding body 8.

The assembly detection unit 24, the first fixed auxiliary detection unit 25, the detection display unit 26, and the second fixed auxiliary detection unit 27 enable the assembly and detection of the columnar tube 18 and the U-shaped serpentine tube 21 to be carried out synchronously.

[0034] like Figure 2 , 3As shown in Figure 4, the feeding body 8 includes a second electric push rod 9, a first storage frame 10, a third electric push rod 11, a first positioning plate 12, a fixed connecting plate 13, a second storage frame 14, a telescopic support plate 15, a control cross plate 16, a fourth electric push rod 22, and a second positioning plate 23. The second storage frame 14 is located on one side of the first storage frame 10. The fixed connecting plate 13 is fixedly connected between the upper ends of the second storage frame 14 and the first storage frame 10 by bolts. The second electric push rods 9 are evenly and symmetrically fixedly installed on the outer ends of the first storage frame 10 and the second storage frame 14. The control cross plate 16 is evenly distributed on both sides of the first storage frame 10 and the second storage frame 14.

Evenly distributed telescopic trays 15 are slidably inserted into the interior of both sides of the first storage frame 10 and the second storage frame 14. The first positioning plate 12 and the second positioning plate 23 are slidably positioned at the connection point of the first storage frame 10 and the second storage frame 14. The third electric push rod 11 and the fourth electric push rod 22 are fixedly installed at the upper and lower ends of the first storage frame 10, respectively. The front end of the third electric push rod 11 is fixedly connected to the upper end of the first positioning plate 12, and the front end of the fourth electric push rod 22 is fixedly connected to the bottom end of the second positioning plate 23. Columnar tubes 18 are evenly stacked on both sides of the interior of the first storage frame 10, and positioning plates 17 are evenly fixedly installed on the columnar tubes 18. The second storage frame 14... U-shaped coiled tubes 21 are evenly arranged inside the tube. Fixed flanges 20 are fixedly installed at the connection points of the U-shaped coiled tubes 21 and the columnar tube body 18. A detection plate 19 is fixedly connected to the side of the fixed flange 20 connected to the columnar tube body 18. Telescopic support plates 15 are inserted into the gaps between the evenly arranged columnar tube bodies 18 and the U-shaped coiled tubes 21. The edges of both ends of the U-shaped coiled tubes 21 are provided with slots for securing the ends of the columnar tube bodies 18. Sealing gaskets are installed inside the slots. After the front end of the columnar tube body 18 is inserted into the slot, the columnar tube body 18 and the U-shaped coiled tube 21 are aligned and fitted together. The columnar tube body 18 and the U-shaped coiled tube 21 are then assembled. The cylindrical tubes 18 and U-shaped tubes 21 are neatly stacked inside the first storage frame 10 and the second storage frame 14 for storage, enabling automatic feeding. This allows the device to continuously, automatically, and stably assemble and inspect the cylindrical tubes 18 and U-shaped tubes 21. The evenly distributed second electric push rods 9 control the lateral movement of the control plates 16 and telescopic trays 15 on both sides of the first and second storage frames 10 and 14. This allows each telescopic tray 15 to be inserted into the gaps between the evenly stacked cylindrical tubes 18 and U-shaped tubes 21, ensuring that the bottoms of the cylindrical tubes 18 and U-shaped tubes 21 stacked inside the first and second storage frames 10 and 14 are independently supported.

And when the first storage frame... After the cylindrical tubes 18 and U-shaped coiled tubes 21 are evenly stacked inside the first storage frame 10 and the second storage frame 14, the third electric push rod 11 and the fourth electric push rod 22 are activated. These activate the first positioning plate 12 and the second positioning plate 23, respectively. The moving first positioning plate 12 presses one end of the cylindrical tubes 18 evenly stacked inside the first storage frame 10, ensuring that the cylindrical tubes 18 are neatly placed inside the first storage frame 10. Similarly, the pressing and adjusting action of the second positioning plate 23 ensures that the U-shaped coiled tubes 21 are neatly placed inside the second storage frame 14. This ensures that the cylindrical tubes 18 and U-shaped coiled tubes 21 neatly stacked inside the first and second storage frames 10 and 14 can accurately land at the same position, resulting in precise positioning when automatically adding and replenishing the cylindrical tubes 18 and U-shaped coiled tubes 21.

The second laser rangefinder 42 is symmetrically arranged at the end of the second assembly limiting frame 43 near the first assembly limiting frame 39.The first assembly limiting frame 39 and the second assembly limiting frame 43 enable precise assembly and detection of the cylindrical tube 18 and the U-shaped serpentine tube 21 after positioning. The gas detection sensor 40 is a helium mass spectrometer leak detector sensor, a photoionization sensor, or an infrared gas sensor.

[0036] like Figure 8 As shown, the detection display unit 26 includes a fixing frame 50, an eighth electric push rod 51, a ninth electric push rod 52, a clamping frame 53, and a white detection cloth 54. The clamping frames 53 are symmetrically distributed, and the white detection cloth 54 is located between the two clamping frames 53. The two sides of the white detection cloth 54 are clamped and fixed inside the clamping frames 53. The fixing frames 50 are evenly and symmetrically distributed. The eighth electric push rod 51, which is evenly distributed on the outside of the clamping frames 53, is fixedly installed on the fixing frame 50, and the front end of the eighth electric push rod 51 is fixedly connected to the outside of the clamping frame 53. The ninth electric push rod 52 is evenly fixedly installed at the bottom of the clamping frame 53, and the front end of the ninth electric push rod 52 passes through the clamping frame 53 and presses against the white detection cloth 54. The white detection cloth 54 allows for quick and convenient observation of the detection results.

[0037] like Figure 9 As shown, the second fixed auxiliary detection unit 27 includes a tenth electric push rod 55, a fixed mounting bracket 56, a pressure sensor 57, a fixed mounting plate 58, a buffer spring 59, a compression fixing plate 60, and a side sliding plate 61. The tenth electric push rod 55 is fixedly mounted on the fixed mounting bracket 56. The pressure sensor 57 is fixedly mounted on the front end of the tenth electric push rod 55 by bolts. The fixed mounting plate 58 is fixedly mounted on the side end of the pressure sensor 57 away from the tenth electric push rod 55 by bolts. The buffer spring 59 is fixedly connected between the compression fixing plate 60 and the fixed mounting plate 58. The side sliding plate 61 is fixedly arranged on both sides of the compression fixing plate 60. The fixed mounting plate 58 is used to detect and monitor the compression force at the compression fixing plate 60.

[0038] The side sliding plate 61 in the second fixed auxiliary detection unit 27 has an arc-shaped extrusion groove in the middle of its front end face, which can be squeezed and fixed to fit the bent end of the U-shaped snake tube 21. The extrusion fixing plate 60 in the second fixed auxiliary detection unit 27 is slidably engaged with the second limiting groove 37 set at the end of the first assembly limiting frame 39 through the side sliding plate 61. The extrusion fixing plate 60 in the first fixed auxiliary detection unit 25 is slidably engaged with the second limiting groove 37 set on both sides of the second assembly limiting frame 43 and the first assembly limiting frame 39 through the side sliding plate 61, respectively, to achieve the function of limiting. The fixed mounting bracket 56 is fixedly connected to the outer wall of the first assembly limiting frame 39 and the second assembly limiting frame 43 respectively.

[0039] The limiting support shaft 28 passes through the fixed support base 5 and is fixedly connected to the middle of the rotating gear disk 2. The middle of the rotating gear disk 2 inside the fixed support base 5 without the motor 3 is rotatably engaged with the inner outer end of the fixed mounting bracket 56 at the end of the first assembly limiting frame 39. The bottom end of the first electric push rod 7 is bolted to the first storage frame 10 and the second storage frame 14. The first storage frame 10 and the second storage frame 14 are located directly above the second assembly limiting groove 44 and the first assembly limiting groove 38, respectively. The columnar tube 18 is located inside the second assembly limiting groove 44, and the U-shaped snake tube 21 is located inside the first assembly limiting groove 38. When the columnar tube 18 and the U-shaped snake tube 21 are assembled, the detection plate 19 is located directly in front of the second laser ranging sensor 42, which can realize auxiliary position detection. The upper ends of the fixing brackets 50 on both sides of the white detection cloth 54 are fixedly connected to the bottom ends of the track support plate 29 and the first assembly limiting frame 39, respectively, to play a fixed connection role.

[0040] Working principle: The device can be fixedly installed at a designated position through the fixing hole at the bottom of the fixed support base 5. The two columnar tubes 18 are placed inside the second assembly limiting grooves 44 on both sides of the second assembly limiting frame 43, and the U-shaped snake tube 21 is placed inside the first assembly limiting groove 38 on the first assembly limiting frame 39. The tenth electric push rod 55 in the second fixing auxiliary detection unit 27 and the first fixing auxiliary detection unit 25 on both sides of the first assembly limiting frame 39 is activated. Through the tenth electric push rod 55 on both sides and at the end of the first assembly limiting frame 39, the pressing fixing plate 60 is pushed to simultaneously press the U-shaped snake tube in the first assembly limiting groove 38. The tube 21 is fixed in the first assembly limiting groove 38 by three-point extrusion. The pressure sensor 57 detects and monitors the extrusion force exerted by the tenth electric push rod 55 on the extrusion fixing plate 60. This allows the extrusion fixing plates 60 at both sides and ends of the first assembly limiting frame 39 to apply a preset extrusion force to the U-shaped tube 21 inside the first assembly limiting groove 38. This ensures that the extruded U-shaped tube 21 is precisely fixed inside the first assembly limiting groove 38. At this point, the bent end of the U-shaped tube 21 fits against the partition block in the middle of the first assembly limiting frame 39, ensuring a firm fixation. This also allows the U-shaped tubes 21 continuously placed in the first assembly limiting groove 38 to... 1. The positions are the same after compression and fixing adjustment during assembly, which can achieve precise positioning during automatic assembly. The buffer spring 59 plays a buffering and protective role. Similarly, the first fixing auxiliary detection part 25 set on both sides of the second assembly limiting frame 43 can press and fix the columnar tube 18 placed inside the second assembly limiting groove 44 on both sides of the second assembly limiting frame 43 with a preset extrusion force. Furthermore, the front end of the sixth electric push rod 35 symmetrically installed in the middle of the second assembly limiting frame 43 retracts a specified distance, so that the side extrusion fixing plate 34 set on the inner end of the second assembly limiting groove 44 synchronously extrudes and limits the inner end of the columnar tube 18 inside the second assembly limiting groove 44. Furthermore, the first laser rangefinder 32 can detect the amount of movement of the adjustment plate 36, so that the columnar tube 18 in the second assembly limiting groove 44 is squeezed and limited by the side compression fixing plate 34 and the compression fixing plate 60 respectively, so that the columnar tube 18 placed in the second assembly limiting groove 44 is accurately positioned after being fixed, and the columnar tubes 18 placed in the second assembly limiting groove 44 are accurately positioned and identical after being fixed, so that assembly can be continuously achieved. When the specified extrusion force of the U-shaped snake tube 21 inside the first assembly limiting groove 38 and the columnar tubes 18 in the two second assembly limiting grooves 44 is fixed at the preset position, the assembly process can be achieved.

[0041] During assembly, firstly, the fifth electric push rods 31 located on both sides of the track support plate 29 are activated. These fifth electric push rods 31 adjust the second assembly limiting frame 43 along the track support plate 29, sliding it a preset distance before stopping. This aligns the front ends of the two columnar tubes 18 fixed inside the second assembly limiting frame 43 with the two ends of the U-shaped serpentine tube 21. Then, the seventh electric push rod 49 is activated, pushing the assembly push seat 46 to slide along the track support plate 29. This allows the two locking and pressing plugs 45 located inside the assembly push seat 46 to be precisely inserted into the ends of the columnar tubes 18 facing away from the U-shaped serpentine tube 21. At this point, the seventh electric push rod 49 is stopped, and then the second assembly limiting frame 43 is simultaneously activated. The tenth electric push rod 55 in the first fixed auxiliary detection unit 25 on the side causes the front-end compression fixing plate 60 to retract a certain distance, releasing the compression force on the side of the columnar tube 18. Then, the sixth electric push rod 35 is activated to release the compression force of the side compression fixing plate 34 on the inside of the columnar tube 18. Then, the seventh electric push rod 49 is activated to push the assembly push seat 46 to slide along the track support plate 29 a specified preset distance. Thus, by inserting the locking compression plug 45 into the inside of the columnar tube 18, the front end of the columnar tube 18 can be pushed into the inside of the end of the U-shaped coil 21, realizing the alignment and assembly between the columnar tube 18 and the U-shaped coil 21. At this time, the fixing flange 2 on the columnar tube 18 and the U-shaped coil 21 is also installed. The alignment is achieved by uniformly arranging positioning plates 17 on the columnar tube 18. After the columnar tube 18 is pressed and fixed by the positioning plates 17, the fixing holes on the fixing flange 20 at the end of the columnar tube 18 align with the fixing holes on the fixing flange 20 at the end of the U-shaped tube 21. This allows the middle portion of the columnar tube 18 to be pre-inserted into the groove at the end of the U-shaped tube 21, pressing the internal rubber sealing gasket. Furthermore, fixing bolts are installed into the fixing holes on the aligned fixing flange 20 using external assembly equipment. This allows the columnar tube 18 to be quickly and securely assembled with the U-shaped tube 21. A detection plate 19 is located on the side of the fixing flange 20, positioned near the second laser measuring... Directly in front of the distance sensor 42, when the columnar tube 18 is placed inside the second assembly limiting groove 44, the detection plate 19 is located directly in front of the second laser distance sensor 42. The front of the second laser distance sensor 42 is blocked by the detection plate 19. At this time, the second laser distance sensor 42 can help analyze and judge whether the columnar tube 18 is placed accurately by detecting and analyzing the change in the distance value between itself and the blocking object in front. This allows the four threaded fixing holes on the fixing flange 20 on the columnar tube 18 and the U-shaped snake tube 21 to be accurately and conveniently aligned during assembly, so that the columnar tube 18 and the U-shaped snake tube 21 can be accurately, automatically and quickly assembled.

[0042] After the cylindrical tube 18 and the U-shaped coiled tube 21 are assembled, the seventh electric push rod 49 is activated to continue pressing the clamping and squeezing plug 45 against the end of the cylindrical tube 18 away from the U-shaped coiled tube 21. This causes the sealing gasket 47 to seal the end of the cylindrical tube 18. The colored detection liquid is then delivered through the clamping and squeezing plug 45 into the cylindrical tube 18 and the U-shaped coiled tube 21 via the connecting pipe 30 and the delivery hose, secured by a steel wire. High pressure is generated inside. If the seal between the columnar tube 18 and the U-shaped coil 21 is incomplete, colored liquid inside the columnar tube 18 and the U-shaped coil 21 will drip from the connection point onto the white detection cloth 54, staining it. This allows for quick and easy detection. If no colored liquid drips onto the white detection cloth 54 within the specified time, it indicates that the columnar tube 18 is not properly sealed. The cylindrical tube 18 and the U-shaped serpentine tube 21 are well sealed during assembly. The two sides of the white detection cloth 54 are placed inside the clamping frame 53 and are squeezed and fixed by the ninth electric push rod 52. The white detection cloth 54 can be laid flat and opened by the eighth electric push rods 51 on both sides, which also makes it easy to replace the white detection cloth 54. Gas detection sensors 40 are set on both sides of the first assembly limit frame 39 near the second assembly limit frame 43. Through the delivery hose and connecting pipe 30 and the clamping and squeezing plug 45, safe gas that is easy to detect, such as helium, nitrogen or a mixture of gas with tracer added, can be delivered into the cylindrical tube 18 and the U-shaped serpentine tube 21. When the sealing between the cylindrical tube 18 and the U-shaped serpentine tube 21 is poor, the gas overflow can be accurately detected by the gas detection sensor 40 and delivered to the internal control system of the external system, thereby controlling the operation of the external alarm. This makes the detection method diverse and accurate, and also allows the device to complete the detection synchronously when the cylindrical tube 18 and the U-shaped serpentine tube 21 are assembled.

[0043] In addition to the sealing test of the assembly connection end mentioned above, this device can also test the strength of the columnar tube 18 and the U-shaped serpentine tube 21. After the columnar tube 18 and the U-shaped serpentine tube 21 are assembled and fixedly connected, the tenth electric push rod 55 in the first fixed auxiliary detection unit 25 and the second fixed auxiliary detection unit 27 is activated again. The tenth electric push rod 55 and the pressure sensor 57 control each extrusion fixing plate 60 to press the columnar tube 18 and the U-shaped serpentine tube 21 with a specified extrusion force. Then, after the assembled columnar tube 18 and the U-shaped serpentine tube 21 are discharged from this device, the assembled columnar tube 18 and the U-shaped serpentine tube 21 are extracted at any time to observe whether there is serious deformation on the columnar tube 18 and the U-shaped serpentine tube 21, thereby assisting in the detection of the strength of the columnar tube 18 and the U-shaped serpentine tube 21.

[0044] After the columnar tube 18 and U-shaped serpentine tube 21 are assembled and inspected, the motor 3 is started to drive the drive gear 4 inside the fixed support base 5 on one side to rotate. The rotating drive gear 4 drives the rotating gear disk 2 to rotate, which in turn drives the limiting support shaft 28 to rotate. The rotating limiting support shaft 28 then drives the entire assembly and inspection unit 24 to rotate, allowing the assembled columnar tube 18 and U-shaped serpentine tube 21 to be easily discharged from the assembly and inspection unit 24. Furthermore, during use, this device can neatly stack the columnar tube 18 and U-shaped serpentine tube 21 to be assembled inside the first storage frame 10 and the second storage frame 14 for storage, achieving automatic feeding. This device can continuously, automatically, and stably assemble and inspect the columnar tubes 18 and U-shaped coiled tubes 21. The evenly distributed second electric push rods 9 control the lateral movement of the control plates 16 and telescopic trays 15 on both sides of the first storage frame 10 and the second storage frame 14, allowing each telescopic tray 15 to be inserted into the gaps between the evenly stacked columnar tubes 18 and U-shaped coiled tubes 21. This ensures that the bottoms of the columnar tubes 18 and U-shaped coiled tubes 21 stacked inside the first storage frame 10 and the second storage frame 14 are independently supported, facilitating the addition of columnar tubes 18 and U-shaped coiled tubes 21 into the first storage frame 10 and the second storage frame 14. It also ensures that the columnar tubes 18 and U-shaped coiled tubes 21 are neatly stacked inside the first storage frame 10 and the second storage frame 14. After the tube 21 moves outward via the second electric push rod 9, controlling the horizontal plate 16 and the telescopic support plate 15 to remove their support for the bottom of the columnar tube 18 and the U-shaped serpentine tube 21, the neatly stacked columnar tubes 18 or U-shaped serpentine tubes 21 can be discharged one by one from the inside of the first storage frame 10 or the second storage frame 14. Furthermore, the first electric push rod 7 can control the overall height of the feeding body 8, control the distance between the bottom of the feeding body 8 and the assembly detection body 6, and adjust the position of the second assembly limiting frame 43, so that the falling columnar tubes 18 and U-shaped serpentine tubes 21 can accurately enter the inside of the second assembly limiting groove 44 and the first assembly limiting groove 38, achieving continuous, precise, and automatic material replenishment. And when the first storage frame 10 and the second... After the cylindrical tubes 18 and U-shaped coiled tubes 21 are evenly arranged inside the second storage frame 14, the third electric push rod 11 and the fourth electric push rod 22 are activated. These actions move the first positioning plate 12 and the second positioning plate 23, respectively. The moving first positioning plate 12 presses one end of the cylindrical tubes 18 evenly arranged inside the first storage frame 10, ensuring that the cylindrical tubes 18 are neatly placed inside the first storage frame 10. Similarly, the pressing and adjustment by the second positioning plate 23 ensures that the U-shaped coiled tubes 21 are neatly placed inside the second storage frame 14. Thus, the cylindrical tubes 18 and U-shaped coiled tubes 21 neatly arranged inside the first and second storage frames 10 can accurately achieve the same landing point.This ensures precise positioning when automatically adding and supplementing the columnar tube 18 and U-shaped serpentine tube 21.
