Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an intelligent assembly device for heat exchange tubes. Background Technology

[0002] A heat exchanger, also known as a heat exchanger or heat exchange equipment, is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction.

[0003] In the production process of heat exchangers, heat exchange tubes are the core components, and their assembly efficiency and accuracy directly affect the performance and manufacturing cost of the heat exchange equipment. Because heat exchange tubes are relatively long (generally ranging from 2m to 10m) and heavy, and each heat exchanger needs to be assembled with hundreds or even thousands of heat exchange tubes, these heat exchange tubes need to be fixed by perforated plates, and the perforation accuracy requirements are high.

[0004] Currently, the perforation process for heat exchanger tubes and orifice plates mainly relies on manual operation. This not only requires a large number of workers to work together, but is also extremely labor-intensive and inefficient. In addition, manual operation poses high safety risks, such as frequent workplace accidents. Furthermore, manual assembly has low precision and high labor costs.

[0005] Therefore, there is an urgent need to design an intelligent heat exchanger tube assembly device to solve the above-mentioned technical problems. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0075] This embodiment discloses an intelligent heat exchanger tube assembly device. By integrating advanced automation technology, precision positioning and intelligent control, the intelligent heat exchanger tube assembly device realizes fully controllable automation of the entire process from material feeding, positioning, perforation to fixing of the heat exchanger tube 402, thereby improving production efficiency, reducing manufacturing costs and ensuring operational safety.

[0076] like Figures 1 to 3 As shown, the intelligent heat exchanger tube assembly equipment in this embodiment includes a control system, a feeding platform 400, and a conveying platform 200. The feeding platform 400 is used to place the heat exchanger tube 402. The feeding platform 400 is configured to move up and down along the height direction according to the orifice plate assembly information provided by the control system. The feeding platform 400 is located on one side of the conveying platform 200 along the first direction A. The discharge port of the feeding platform 400 is higher than the conveying platform 200 to deliver the heat exchanger tube 402 to the conveying platform 200. The conveying platform 200 is configured to drive the heat exchanger tube 402 to move and position along the first direction A according to the orifice plate assembly information provided by the control system. It can also drive the heat exchanger tube 402 to move along the second direction B to assemble with the orifice plate 300 through the hole. The first direction A and the second direction B are perpendicular to each other and both are perpendicular to the height direction. The conveying platform 200 is also configured to move up and down along the height direction according to the orifice plate assembly information provided by the control system. In this embodiment, the perforated plate 300 is laid flat along the height direction. The first direction A and the second direction B are both directions within a horizontal plane perpendicular to the height direction. This can be understood as the first direction A and the second direction B being directions on the plane where the conveying platform 200 is located. Specifically, the second direction B is perpendicular to the surface of the perforated plate 300, and the first direction A is perpendicular to the second direction B. For example... Figure 2 As shown, the feeding platform 400 is located on one side of the conveying platform 200 along the first direction A. The heat exchange tube 402 on the feeding platform 400 is conveyed to the conveying platform 200 along the first direction A. The conveying platform 200 can drive the heat exchange tube 402 to move and position along the first direction A according to the orifice plate assembly information provided by the control system, so as to match the position of the assembly hole on the orifice plate 300. After the horizontal positioning is completed, the conveying platform 200 drives the heat exchange tube 402 to move along the second direction B toward the orifice plate 300 to be assembled with the orifice plate 300 through the hole.

[0077] It should be noted that the aforementioned "orifice plate assembly information" may include the dimensions of the orifice plate 300, hole position information, and the dimensions of the heat exchange tube 402. Specifically, the dimensions of the orifice plate 300 include its length, width, and height; the hole position information includes the location and diameter of the assembly holes on the orifice plate 300, such as the height of the assembly hole and its left / right position in the first direction A; and the dimensions of the heat exchange tube 402 include its length and outer diameter. In this embodiment, the control system controls the assembly sequence of the intelligent heat exchange tube assembly equipment as follows: from top to bottom, and from farthest to closest to the unloading platform 400, sequentially perforating and assembling the tubes.

[0078] Compared to manual perforation assembly, the intelligent heat exchanger assembly equipment in this embodiment connects the feeding platform 400 and the conveying platform 200 to the control system respectively. This enables automatic horizontal and vertical positioning of the heat exchanger tube 402 based on the orifice plate assembly information before assembly. This improves the perforation assembly accuracy and production efficiency of the heat exchanger tube 402 and the orifice plate 300, while reducing the labor intensity and safety risks of workers, effectively reducing labor costs, improving the consistency of production quality, and thus reducing the overall manufacturing cost.

[0079] The intelligent heat exchanger tube assembly equipment also includes a lifting platform 100, which is connected to the control system. The lifting platform 100 is configured to move up and down in the height direction according to the orifice plate assembly information provided by the control system. The unloading platform 400 and the conveying platform 200 can be respectively mounted on the lifting platform 100, or the unloading platform 400 can be mounted on the conveying platform 200, with only the conveying platform 200 mounted on the lifting platform 100. The lifting platform 100 is used to position the heat exchanger tube 402 in the height direction. In actual production, the height positioning of the heat exchanger tube 402 is completed first, followed by the horizontal positioning, and finally the assembly of the heat exchanger tube 402 with the orifice plate 300 is achieved. In this embodiment, only the conveying platform 200 is mounted on the lifting platform 100, while the unloading platform 400 is mounted on the conveying platform 200, which improves the overall integrity of the equipment.

[0080] Since the orifice plate 300 is typically large, a two-stage lifting platform 100 is used to position the heat exchange tube 402 at its height. Specifically, the lifting platform 100 includes a base 101, a primary lifting mechanism 110, and a secondary lifting mechanism 120. Both the primary and secondary lifting mechanisms 110 and 120 are connected to the control system. The primary lifting mechanism 110 is mounted on the base 101, and the secondary lifting mechanism 120 is positioned above it. The discharge platform 400 and the conveying platform 200 are respectively mounted on the secondary lifting mechanism 120, or only the conveying platform 200 may be mounted on the secondary lifting mechanism 120. When the orifice plate 300 is small, only the primary lifting mechanism 110 is used for lifting to position the heat exchange tube 402 in the height direction. When the orifice plate 300 is large, both the primary and secondary lifting mechanisms 110 and 120 must be used simultaneously to position the heat exchange tube 402 in the height direction to accommodate the height of the orifice plate 300. The two-stage lifting platform 100 can meet the perforation assembly requirements of perforated plates 300 of different sizes, improving the versatility of the intelligent heat exchanger assembly equipment. In this embodiment, the conveying platform 200 is set on the two-stage lifting mechanism 120, and the unloading platform 400 is set on the conveying platform 200. The lifting of the two-stage lifting platform 100 realizes the synchronous lifting of the unloading platform 400 and the conveying platform 200.

[0081] Optionally, both the primary lifting mechanism 110 and the secondary lifting mechanism 120 are scissor-type lifting mechanisms, and both are driven by the hydraulic mechanism 102.

[0082] In this embodiment, the conveying platform 200 includes a platform plate, a conveying assembly, and a horizontal positioning assembly. Both the conveying assembly and the horizontal positioning assembly are mounted on the platform plate and connected to the control system. The horizontal positioning assembly is configured to drive the heat exchange tube 402 to move and position along a first direction A. The conveying assembly is configured to drive the heat exchange tube 402 to move along a second direction B and assemble it through a hole in the perforated plate 300. The platform plate, as the supporting structure of the conveying platform 200, is mounted on the lifting platform 100, specifically on the secondary lifting mechanism 120. Optionally, the platform plate is a rectangular plate, with its width direction being the first direction A and its length direction being the second direction B. The unloading platform 400 is located on one side of the platform plate in the width direction, and the perforated plate 300 is located on one side of the platform plate in the length direction. The conveying assembly, as the supporting and driving structure for the heat exchange tube 402, receives the heat exchange tube 402 from the unloading platform 400 and conveys the heat exchange tube 402 from the conveying platform 200 to the perforated plate 300 for assembly through a hole. The horizontal positioning component is used to position the heat exchange tube 402 in the horizontal plane before the conveying component moves the heat exchange tube 402 along the second direction B. Specifically, it drives the heat exchange tube 402 to move along the first direction A in a direction away from the discharge platform 400. Of course, the positioning of the heat exchange tube 402 by the horizontal positioning component is based on the orifice plate assembly information provided by the control system.

[0083] Further, the conveying assembly includes multiple first driving elements 210 and multiple conveying shafts 211. The conveying shafts 211 extend along a first direction A, and the multiple conveying shafts 211 are spaced apart along a second direction B. The heat exchange tube 402 is supported on the conveying shafts 211. The multiple first driving elements 210 and the multiple conveying shafts 211 are connected one-to-one. The first driving elements 210 are connected to the control system and are used to drive the conveying shafts 211 to rotate, thereby moving the heat exchange tube 402 along the second direction B. The heat exchange tube 402 extends along the second direction B, perpendicular to the extension direction of the conveying shafts 211. When the heat exchange tube 402 is conveyed from the discharge platform 400 along the first direction A to the conveying platform 200, the multiple conveying shafts 211 jointly support the heat exchange tube 402. When the horizontal positioning assembly completes the horizontal positioning of the heat exchange tube 402, as... Figure 1 As shown, the first driving member 210 drives the corresponding conveying shaft 211 to rotate clockwise, thereby driving the heat exchange tube 402 supported on the conveying shaft 211 to move along the second direction B towards the perforated plate 300, completing the through-hole assembly with the perforated plate 300. Optionally, the first driving member 210 is a synchronous motor, and the control system controls multiple first driving members 210 to operate simultaneously, thereby ensuring that multiple conveying shafts 211 rotate synchronously and stably convey the heat exchange tube 402. The first driving member 210 is located at one end of the conveying shaft 211.

[0084] Optionally, multiple conveying shafts 211 are arranged at equal intervals along the second direction B. This ensures that the conveying shafts 211 provide stable and uniform support for the heat exchange tube 402, thereby guaranteeing the stability of the movement of the heat exchange tube 402. The conveying shafts 211 are cylindrical and can rotate under the drive of the first driving member 210. Their dimensions are designed according to the length of the heat exchange tube 402 and the assembly requirements.

[0085] To enable the rotation of the conveyor shaft 211, the conveying assembly also includes an electric rolling bearing 201, a bearing fixing plate 202, and a support column 203. The support column 203 is fixed on the platform plate, the bearing fixing plate 202 is fixed on the support column 203, the outer ring of the electric rolling bearing 201 is fixedly connected to the bearing fixing plate 202, and the inner ring of the electric rolling bearing 201 is fixedly connected to the conveyor shaft 211. This structure enables the conveyor shaft 211 to rotate relative to the platform plate.

[0086] The outer periphery of the conveyor shaft 211 is wrapped with an elastic anti-friction layer. This layer protects the heat exchange tube 402 while also increasing the friction with it, thus improving the conveying of the heat exchange tube 402. Optionally, the elastic anti-friction layer is a frosted rubber pad.

[0087] In this embodiment, such as Figure 4As shown, the horizontal positioning assembly includes a first guide rail 221, a rolling element 223, and a second driving element 220. The first guide rail 221 extends along a first direction A, and at least two first guide rails 221 are provided. All first guide rails 221 are spaced apart along a second direction B, and all first guide rails 221 are located directly below the corresponding conveying shaft 211. The rolling element 223 is provided at least on the conveying shaft 211 corresponding to the first guide rail 221. That is, at least two rolling elements 223 are provided on the same straight line along the second direction B. The rolling element 223 is configured to support the heat exchange tube 402 and can move along the conveying shaft 211, thereby driving the heat exchange tube 402 to move along the first direction A. The rolling element 223 can rotate relative to the conveying shaft 211. When the heat exchange tube 402 moves towards the second direction B, the rolling element 223 rotates relative to the conveying shaft 211, thereby not affecting the movement of the heat exchange tube 402. The second driving element 220 is mounted on the first guide rail 221 and connected to the control system. The number of second driving elements 220 is the same as the number of rolling elements 223, and the output end of the second driving element 220 is connected to the rolling element 223. The second driving element 220 is used to drive the rolling element 223 to move and position along the first direction A, thereby driving the heat exchange tube 402 to move and position along the first direction A, achieving horizontal positioning of the heat exchange tube 402. In this structure, each heat exchange tube 402 is fed from the feeding platform 400 to the conveying platform 200 along the first direction A, specifically supported on at least two rolling elements 223. The control system controls the second driving element 220 to drive the corresponding rolling element 223 to move and position along the first direction A according to the orifice plate assembly information. The rolling element 223 drives the heat exchange tube 402 to move, thereby achieving positioning of the heat exchange tube 402. Optionally, the second driving element 220 is a motor.

[0088] To facilitate the receiving of the heat exchange tube 402 and to drive the heat exchange tube 402 to move and be positioned horizontally, the surface of the rolling element 223 is provided with an arc-shaped groove for accommodating the heat exchange tube 402, thereby improving the support stability of the rolling element 223 for the heat exchange tube 402.

[0089] Furthermore, the horizontal positioning component also includes a connecting shaft 222, one end of which is connected to the output end of the second drive member 220, and the other end is connected to the rolling member 223. Specifically, the connecting shaft 222 is vertically arranged, and the second drive member 220 is connected to the rolling member 223 through the connecting shaft 222 to realize the transmission of power.

[0090] In another feasible embodiment, the horizontal positioning component further includes at least two second guide rails 224. The second guide rails 224 extend along a first direction A, and all the second guide rails 224 are spaced apart along a second direction B. The number of second guide rails 224 is the same as the number of first guide rails 221, and all the second guide rails 224 are arranged one-to-one directly above the first guide rails 221. Rolling elements 223 are at least disposed on the second guide rails 224. The second guide rails 224 are fixed guide rails, meaning they are stationary. The rolling elements 223 can move along the first direction A on the second guide rails 224, and can rotate relative to the second guide rails 224. When the heat exchange tube 402 moves towards the second direction B, the rolling elements 223 rotate relative to the second guide rails 224, thus not affecting the movement of the heat exchange tube 402. In other words, in this embodiment, the second guide rails 224 replace part of the conveying shaft 211 as the moving guide for the rolling elements 223. Optionally, along the second direction B, the second guide rail 224 and the conveying shaft 211 are alternately arranged, that is, at least one conveying shaft 211 is arranged between the two second guide rails 224.

[0091] Optionally, the rolling element 223 in this embodiment is a rolling bearing.

[0092] Optionally, the first guide rail 221 is a rack and pinion guide rail, and the second drive member 220 is equipped with a gear that cooperates with the rack and pinion guide rail. The output shaft of the second drive member 220 is connected to the gear. By controlling the rotation of the gear, the reciprocating movement of the second drive member 220 on the first guide rail 221 can be realized, thereby driving the rolling shaft 223 to move on the second guide rail 224 through the connecting shaft 222.

[0093] In this embodiment, along the first direction A, the feeding platform 400 is inclined downwards towards the conveying platform 200. The discharge port is located at the lowest point of the feeding platform 400, and a feeding switch 401 is provided at the discharge port. The feeding switch 401 is connected to the control system, and the heat exchange tubes 402 can fall onto the conveying platform 200 one by one through the feeding switch 401. The discharge port of the feeding platform 400 is higher than the conveying platform 200. By providing the feeding switch 401 at the discharge port, the heat exchange tubes 402 fall onto the conveying platform 200 one by one under the combined action of gravity and the feeding switch 401. Optionally, two feeding switches 401 are provided at intervals along the second direction B at the discharge port, which can provide more stable and reliable feeding of the tubes one by one. The two feeding switches 401 are located in the middle position of the feeding platform 400.

[0094] Optionally, the discharge switch 401 is a cross-shaped rotating stop arm. Each rotation of the cross-shaped rotating stop arm causes one heat exchange tube 402 to fall onto the conveying platform 200. The rotation of the discharge switch 401 then sends the heat exchange tubes 402 one by one to the conveying platform 200. The remaining heat exchange tubes 402 roll to the discharge switch 401 under gravity, awaiting its next rotation. It should be noted that the cross-shaped rotating stop arm is existing technology, and its working principle will not be elaborated here.

[0095] In this embodiment, a first pressure detection unit 403 is provided on the unloading platform 400. The first pressure detection unit 403 is connected to the control system and is used to detect whether there is a heat exchange tube 402 on the unloading platform 400. When the intelligent heat exchange tube assembly equipment is initially running, if there is no heat exchange tube 402 on the unloading platform 400, the first pressure detection unit 403 will input a signal to the control system, the control system will alarm, and the unloading platform 400 will be lowered to its lowest position so that the heat exchange tube 402 can be placed on the unloading platform 400. After the heat exchange tube 402 is placed, the unloading platform 400 will rise to the assembly height of the heat exchange tube 402.

[0096] A second pressure detection unit 225 is installed on the conveyor shaft 211 closest to the orifice plate 300. The second pressure detection unit 225 is connected to the control system and is used to detect whether there is a heat exchange tube 402 on the conveyor shaft 211. When the second pressure detection unit 225 detects that the pressure becomes 0, the conveyor shaft 211 stops rolling, that is, one perforation of the heat exchange tube 402 is completed, and the horizontal positioning assembly begins the next set of hole positioning, preparing for the next perforation.

[0097] Optionally, both the first pressure detection unit 403 and the second pressure detection unit 225 are pressure sensors.

[0098] The intelligent heat exchanger assembly equipment in this embodiment also includes an orifice plate platform, which is located on one side of the conveying platform 200 along the second direction B. The orifice plate platform includes an orifice plate support 301, the orifice plate 300, and a fixing rod 302. The orifice plate 300 is supported on the orifice plate support 301 and extends along the first direction A, that is, the plate surface of the orifice plate 300 is perpendicular to the second direction B. Multiple orifice plates 300 are spaced apart along the second direction B. The fixing rod 302 extends along the second direction B, and its two ends are respectively connected to two orifice plates 300 to form a frame structure with the orifice plates 300.

[0099] Optionally, there are four fixing rods 302, divided into two groups: a top rod group and a bottom rod group. The top rod group is located at the top of the orifice plate 300, and the bottom rod group is located at the bottom of the orifice plate 300. Both the top rod group and the bottom rod group include two fixing rods 302.

[0100] Specifically, the two fixing rods 302 in the top rod assembly are spaced apart along the first direction A, with the spacing being the dimension of the perforated plate 300 along the first direction A. That is, the two fixing rods 302 in the top rod assembly are respectively set at the top ends of the perforated plate 300 along the first direction A. The two ends of one fixing rod 302 are respectively connected to the first end of the top of the innermost perforated plate 300 along the first direction A and the first end of the top of the outermost perforated plate 300 along the first direction A. The two ends of the other fixing rod 302 are respectively connected to the second end of the top of the innermost perforated plate 300 along the first direction A and the second end of the top of the outermost perforated plate 300 along the first direction A.

[0101] The two fixing rods 302 in the bottom rod assembly are spaced apart along the first direction A, with the spacing being the dimension of the perforated plate 300 along the first direction A. That is, the two fixing rods 302 in the bottom rod assembly are respectively set at the bottom ends of the perforated plate 300 along the first direction A. The two ends of one fixing rod 302 are respectively connected to the first end of the bottom of the innermost perforated plate 300 along the first direction A and the first end of the bottom of the outermost perforated plate 300 along the first direction A. The two ends of the other fixing rod 302 are respectively connected to the second end of the bottom of the innermost perforated plate 300 along the first direction A and the second end of the bottom of the outermost perforated plate 300 along the first direction A.

[0102] It should be noted that the terms "innermost" and "outermost" are relative to the conveyor platform 200. The end closest to the conveyor platform 200 is the "innermost," and the end farthest from the conveyor platform 200 is the "outermost." It should also be noted that when there are two or more perforated plates 300, a fixing rod 302 is required; when there is only one perforated plate 300, a fixing rod 302 is not required.

[0103] In this embodiment, such as Figure 5 and Figure 6 As shown, the intelligent assembly equipment for heat exchange tubes also includes a support component 500, which is disposed between each pair of adjacent perforated plates 300. The support component 500 is used to support the heat exchange tubes 402 during transportation, ensuring that each heat exchange tube 402 accurately passes through each perforated plate 300, thereby improving the stability and reliability of the perforation process.

[0104] Specifically, the support assembly 500 includes a base 501, a transmission mechanism, a third driving member 504, and a support rod 505. Two bases 501 are provided, each located at one end of the first direction A, serving as the support structure for the support assembly 500. The transmission mechanism includes a ball screw 502 and a slider. The ball screw 502 is mounted on the base 501 and extends upwards along the height direction, while the slider is slidably fitted around the outer periphery of the ball screw 502. The third driving member 504 is connected to the control system and is used to drive the ball screw 502 to rotate, thereby driving the slider to move up and down along the ball screw 502. The support rod 505 supports the heat exchange tube 402. The support rod 505 extends along the first direction A, and its two ends are rotatably connected to the corresponding sliders, allowing the support rod 505 to rotate around its own central axis, thus achieving the purpose of rotating with the heat exchange tube 402. The third driving component 504 drives the ball screw 502 to rotate according to the height of the heat exchange tube 402, adjusting the position of the slider in the height direction, thereby adjusting the height of the support rod 505. This ensures that the support rod 505 always supports the heat exchange tube 402 during the perforation assembly process, to match the assembly requirements of different heights. A support assembly 500 is provided between the two perforated plates 300 to ensure that the heat exchange tube 402 stably passes through each perforated plate 300.

[0105] In another feasible embodiment, the support assembly 500 includes only one transmission mechanism and one third drive member 504, and also includes a guide mechanism. In this embodiment, two bases 501 are still provided. The transmission mechanism includes a ball screw 502 and a first slider 503. The ball screw 502 is disposed on one base 501 and extends upward in the height direction. The first slider 503 is slidably sleeved on the outer periphery of the ball screw 502. The third drive member 504 is connected to the control system and is used to drive the ball screw 502 to rotate, thereby driving the first slider 503 to move up and down along the ball screw 502. The guide mechanism includes a slide rod 506 and a second slider 507. The slide rod 506 is disposed on another base 501 and extends upward in the height direction. The second slider 507 is slidably sleeved on the outer periphery of the slide rod 506. The two ends of the support rod 505 along the first direction A are rotatably connected to the first slider 503 and the second slider 507, respectively, so that the support rod 505 can rotate around its own central axis to achieve the purpose of following the rotation of the heat exchange tube 402. The third driving component 504 drives the ball screw 502 to rotate according to the height of the heat exchange tube 402, adjusts the position of the first slider 503 in the height direction, thereby adjusting the height of the support rod 505, ensuring that the support rod 505 always supports the heat exchange tube 402 during the perforation assembly process, so as to match the assembly requirements of different heights.

[0106] To facilitate adjustment of the position of the support assembly 500, the support assembly 500 also includes wheels, which are disposed at the bottom of the base 501. Optionally, the wheels can be outward-facing wheels or directional pulleys. In this embodiment, the wheels are omnidirectional wheels.

[0107] The control system in this embodiment uses a programmable logic controller (PLC) as the core control unit, equipped with a human-machine interface (HMI), input module, sensor interface, actuator interface, and communication module. The HMI allows operators to interact with the control system, such as setting assembly parameters, monitoring the assembly process, and displaying fault information. The input module is used to input information such as the dimensions of the orifice plate 300, hole position information, and the dimensions of the heat exchange tube 402. The sensor interface connects various sensors, such as pressure sensors and pressure detection devices, and collects sensor data in real time. The actuator interface connects the actuators of each module, such as drive devices, drive motors, and hydraulic mechanisms 102, to achieve precise control of each module. The communication module communicates with other equipment or a host computer to achieve remote monitoring and management. The control system coordinates the control of the conveying components, horizontal positioning components, and lifting platform 100 based on the preset assembly program and sensor feedback. During the assembly process, the control system monitors the operating status of each module and sensor data in real time. If any abnormality is detected, an alarm is immediately issued and corresponding measures are taken, such as stopping equipment operation and adjusting control parameters, to ensure the safety and reliability of the assembly process.

[0108] This embodiment proposes an efficient and precise automated assembly mechanism for heat exchanger tubes. This system can be easily operated by a single person to automatically pierce the heat exchanger tube 402, significantly improving production efficiency, reducing labor intensity and safety risks, while ensuring assembly accuracy and optimizing equipment manufacturing costs.

[0109] The working process of the intelligent heat exchanger tube assembly equipment in this embodiment will be briefly described below.

[0110] When drilling begins, the frame structure consisting of the perforated plate 300 and the fixing rod 302 is placed on the perforated plate support 301. The dimensions of the perforated plate 300, the hole position information, and the dimensions of the heat exchange tube 402 are input into the control system. The control system analyzes and processes the hole position information and controls the entire intelligent heat exchange tube assembly equipment to drill sequentially from top to bottom and from farthest to near the unloading platform 400. Initially, there are no heat exchange tubes 402 on the unloading platform 400. The first pressure detection unit 403 feeds a signal back to the control system, and the control system lowers the lifting platform 100 to its lowest position. After the heat exchange tubes 402 are placed on the unloading platform 400, the control system controls the lifting platform 100 to raise the conveying platform 200 to the highest hole position. Figure 3As shown, the rolling element 223 moves to the leftmost end, i.e., the end closest to the feeding platform 400, under the drive of the second driving element 220; the feeding switch 401 on the feeding platform 400 rotates, conveying the heat exchange tube 402 to the first rolling element 223; the second driving element 220 moves to the rightmost end, i.e., the end away from the feeding platform 400, thereby driving the first rolling element 223 and the heat exchange tube 402 to move away from the feeding platform 400; then the second rolling element 223 begins to receive the next heat tube; when multiple rolling elements 223 are all loaded with heat exchange tubes 402, and after positioning along the first direction A according to the assembly information of the orifice plate 300, the conveying shaft 211 rotates under the action of the first driving element 210, conveying multiple heat exchange tubes 402 simultaneously along the second direction B to the orifice plate 300; under the support of the support component 500, multiple heat exchange tubes 402 are simultaneously perforated and assembled.
