[0027] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0028] For ease of description and understanding, please refer to the following descriptions related to positional relationships such as front, back, top, bottom, left, right, outside, and inside in this case. Figure 2 The indicated direction.

[0029] like Figures 1 to 7As shown, the present application provides an automatic bending machine, which includes a rack 100 comprising a mounting table 101. The mounting table 101 is sequentially mounted with a feeding mechanism 1, a direction recognition mechanism 2, a pushing mechanism 3, a bending mechanism 4 and a discharging mechanism 5 from left to right according to the process flow. The rack 100 is the basic support structure of the entire automatic bending machine, and the mounting table 101, as part of the rack 100, provides an installation platform for the feeding mechanism 1, the direction recognition mechanism 2, the pushing mechanism 3, the bending mechanism 4, the discharging mechanism 5 and the linear module 6, etc. These components are orderly installed on the mounting table 101 and arranged in sequence from left to right according to the process flow, forming a coherent production line. The bending mechanism 4 is arranged below and to the right of the pushing mechanism 3, and the discharging mechanism 5 is connected to the right side of the pushing mechanism 3. The feeding mechanism 1 is responsible for placing the heat pipe to be processed on the production line, realizing automatic feeding of the heat pipe, reducing the workload and labor intensity of manual feeding, and improving production efficiency. At the same time, the orderly feeding process can ensure the stability and accuracy of feeding, which helps to ensure the quality consistency of subsequent processing. The direction recognition mechanism 2 accurately recognizes the direction of the heat pipe before it enters the next processing step, providing information for the correct operation of the pushing mechanism 3 and the bending mechanism 4, ensuring that the heat pipe is bent at the predetermined angle and direction, improving the accuracy of bending, reducing the bending rejects caused by incorrect heat pipe direction, and improving product quality and production efficiency. The pushing mechanism 3 pushes the heat pipe that has passed the direction recognition mechanism 2 to the bending mechanism 4, and during the bending process, it adjusts and fixes the position of the heat pipe according to the requirements of the bending mechanism 4. This ensures that the heat pipe can accurately reach the working position of the bending mechanism 4, improving the precision and efficiency of bending, and providing stable workpiece support for the bending mechanism 4, which helps to improve the bending quality. The bending mechanism 4 bends the heat pipe according to the predetermined angle and shape, which is the core working component of the automatic bending machine. It realizes the automatic bending of the heat pipe, greatly improves the bending efficiency and quality consistency compared with traditional manual or semi-automatic bending methods, and can meet the needs of large-scale production. The discharging mechanism 5 is used to discharge the bent heat pipe from the production line. The mounting table 101 also has a linear module 6 suspended in front of the feeding mechanism 1 and the discharging mechanism 5 from left to right according to the process flow, and a material transfer mechanism 7 is slidably arranged on the linear module 6. The material transfer mechanism 7 can move along the linear module 6 to realize the transfer of the heat pipe between the feeding mechanism 1, the direction recognition mechanism 2, the pushing mechanism 3, the bending mechanism 4 and the discharging mechanism 5, and coordinate the material flow between the mechanisms. In specific implementation, a protective shell is arranged on the rack 100 to ensure safety during manual operation and effectively avoid external interference.The linear module 6 provides a linear motion track for the material transfer mechanism 7, enabling it to move along a predetermined path between mechanisms, achieving rapid and accurate transfer of the heat pipe. The high-precision movement of the linear module 6 ensures the movement accuracy of the material transfer mechanism 7, thereby ensuring the accuracy of the heat pipe transfer between mechanisms, improving the stability and efficiency of the production process. The material transfer mechanism 7 transfers the heat pipe from one mechanism to another by sliding on the linear module 6, coordinating the material flow between mechanisms, ensuring the continuity of the production process, and achieving automated transfer of the heat pipe between mechanisms, reducing the workload and errors of manual handling, and improving production efficiency and product quality stability.

[0030] It should be noted that in specific implementation, the present case detects the presence or absence of an object, detects the in-place situation of the object, and triggers the action of each mechanism or changes the state of each mechanism, thereby realizing the cyclic work of each mechanism. Here, the related content is a known technology in the art, and the setting position and number of each inductive switch are not described one by one. In specific implementation, those skilled in the art can adaptively set the corresponding inductive switch to realize the linkage between each mechanism according to the common sense in the art and the mechanisms on the heat pipe automatic processing machine.

[0031] Specifically, as shown in Figures 1-3 The feeding mechanism 1 includes a feeding box 11, a left-to-right inclined inclined plate 12 arranged in the feeding box 11, a lifting plate 13 movably arranged in the feeding box 11, a second lifting cylinder 14 connected to the lower end of the lifting plate 13, and a pushing device 15. The lifting plate 13 is arranged on the right side of the inclined plate 12 and can move up and down relative to the feeding box 11 under the drive of the second lifting cylinder 14. The upper end of the lifting plate 13 is provided with a first material receiving table 131, and the pushing device 15 includes a first telescopic cylinder 151 connected to the front end of the feeding box 11, a first clamping jaw cylinder 153 connected to the first telescopic cylinder 151 through a connecting plate 152. The first clamping jaw cylinder 153 is suspended above the first material receiving table 131.

[0032] As described above, the feeding box 11 serves as the support structure of the feeding mechanism 1, integrates and fixes other components, and provides a closed and stable space for the storage and feeding of materials. The inclined plate 12 is flat and inclined from left to right at a certain angle inside the feeding box 11, with a smooth surface to reduce friction when the material moves. The inclined plate 12 uses gravity to automatically move the heat pipe material placed on it to the right side of the inclined plate 12, achieving automatic arrangement and conveying of the material and reducing manual intervention. The lifting cylinder 14 precisely controls the lifting plate 13 to pick up and lift the material, and the pushing device 15 automatically clamps and moves the material, achieving automation of the entire feeding process, greatly reducing manual operation time, improving feeding efficiency, and thus improving the overall production efficiency of the automatic bending machine. Precise control of the lifting cylinder 14 over the height of the lifting plate 13, as well as the coordinated work of the components of the pushing device 15, ensures that the material is accurately transferred from the inclined plate 12 to the first material receiving table 131 and accurately clamped and moved to the direction recognition mechanism, ensuring feeding accuracy and helping to improve product quality consistency. The automated feeding process reduces the workload of manual handling and operation, reduces the labor intensity of workers, and improves the safety of the working environment.

[0033] In specific implementation, the lifting cylinder 14 is located at the rightmost end of the inclined plate 12, and the lifting plate 13 is at a higher position. The lifting cylinder 14 controls the piston rod to extend according to the preset program or sensor feedback information, driving the lifting plate 13 to descend. As the lifting plate 13 descends, the heat pipe material on the inclined plate 12 rolls down to the first material receiving table 131 at the upper end of the lifting plate 13 under the action of gravity. After the material is received, the lifting cylinder 14 controls the piston rod to retract, driving the lifting plate 13 to rise to an appropriate height, so that the material on the first material receiving table 131 is in a position convenient for clamping. The first telescopic cylinder 151 is started, the piston rod is extended, and the first clamping cylinder 153 is driven by the connecting plate 152 to move close to the first material receiving table 131. When the first clamping cylinder 153 moves to a suitable position above the first material receiving table 131, the clamping jaw is closed to clamp the material on the first material receiving table 131. Then, the first telescopic cylinder 151 retracts the piston rod, driving the first clamping cylinder 153 with the clamped material to move away from the first material receiving table 131, conveying the material to the direction recognition mechanism. After the material is moved, the first telescopic cylinder 151 is extended again, so that the first clamping cylinder 153 returns to the initial position, and at the same time the lifting cylinder 14 is extended, driving the lifting plate 13 to descend, preparing to receive the next batch of material, and so on, continuously feeding the operation.

[0034] Continue as Figures 1-3As shown, further, the feeding mechanism 1 further comprises a movable plate 16 movably arranged in the feeding box 11, the movable plate 16 is connected to the lower end of the feeding box 11 through a first adjusting screw rod 17, and the movable plate 16 is provided with a first adjusting knob 18. By adding the movable plate 16, the adjusting screw rod 17 and the first adjusting knob 18 and other components, the feeding mechanism 1 of the present case can adapt to heat pipes of different lengths, so that the entire automatic bending machine can process heat pipes of various specifications, expand the application range of the equipment, improve the market competitiveness of the equipment, without complex operation and replacement of parts, improve the flexibility and use efficiency of the equipment.

[0035] When it is necessary to feed heat pipes of different lengths, the operator observes the length of the heat pipe and then manually rotates the first adjusting knob 18. The rotation of the first adjusting knob 18 drives the adjusting screw rod 17 connected thereto to rotate. Since the adjusting screw rod 17 cooperates with the nut on the movable plate 16, the rotation of the adjusting screw rod 17 will make the movable plate 16 move linearly in the feeding box 11. The operator adjusts the movable plate 16 to the appropriate position according to the length of the heat pipe, so that the feeding mechanism 1 can stably support and transport the heat pipe of the length. Then, the feeding mechanism 1 follows the normal feeding process to move the heat pipe from the inclined plate 12 to the direction recognition mechanism 2 through the receiving and pushing device 15 of the lifting plate 13, and completes the feeding operation. When it is necessary to replace heat pipes of different lengths, the above adjustment process is repeated.

[0036] As Figure 1 , Figure 2 , Figure 4As shown, the direction recognition mechanism 2 comprises a first positioning device 21, a recognition device 22 located at the rear end of the first positioning device 21, and a support seat 23 located between the first positioning device 21 and the recognition device 22. The first positioning device 21 comprises a second telescopic cylinder 211 connected to the installation table 101, a first rotary cylinder 213 connected to the second telescopic cylinder 211 through a connecting seat 212, and a second clamping cylinder 214 connected to the rear end of the first rotary cylinder 213. The recognition device 22 comprises a first sliding rail 221, a first bracket 222 connected to the first sliding rail 221, and a CCD camera 223 installed on the first bracket 222. The CCD camera 223 has a high-resolution image sensor, which can quickly and clearly collect the image information of the two-dimensional code on the heat pipe and transmit it to the control system for analysis. The automatic recognition of the direction of the heat pipe is realized, and the efficiency and accuracy of the recognition are improved. The lower end of the first bracket 222 is connected to the first sliding rail 221 through a second adjusting knob 224. The second adjusting knob 224 is used to adjust the distance between the recognition device 22 and the first positioning device 21 to adapt to heat pipes of different lengths. The operator can rotate the second adjusting knob 224 according to the length of the heat pipe to move the first bracket 222 on the first sliding rail 221 and adjust the distance between the recognition device 22 and the first positioning device 21 to adapt to heat pipes of different lengths. The universality of the direction recognition mechanism 2 is increased, and the device can process heat pipes of different specifications. The support seat 23 comprises a support frame 231, a material receiving frame 232 connected to the support frame 231, and a second jacking cylinder 233. In specific implementation, a semicircular groove is formed in the material receiving frame 232, and the size and shape of the groove are adapted to most heat pipes. To realize stable support and support heat pipes of different lengths, the support seat 23 is provided with two support frames 231, which are respectively arranged near the first positioning device 21 and the recognition device 22. Among them, the support frame 231 near the recognition device 22 is also connected with a fifth clamping cylinder 234 to further improve the stability of clamping the heat pipe.

[0037] In specific implementation, the heat pipe has a marker such as a groove or a protrusion or a two-dimensional code. In the case mentioned, the heat pipe contains a two-dimensional code for identification. The feeding mechanism 1 pushes the heat pipe to a specific position, and the material transfer mechanism 7 slides on the linear module 6 and clamps the heat pipe pushed by the feeding mechanism 1. The material transfer mechanism 7 continues to slide on the linear module 6 with the heat pipe and places the heat pipe in the semicircular groove of the receiving rack 232. The second telescopic cylinder 211 extends to drive the first rotary cylinder 213 and the second jaw cylinder 214 to approach the heat pipe on the receiving rack 232, and the second jaw cylinder 214 clamps the heat pipe. The first rotary cylinder 213 starts to rotate to drive the heat pipe to rotate, and by trying different angles, it helps to accurately find the two-dimensional code marker on the heat pipe. At the same time, the fifth jaw cylinder 234 is closed to assist in fixing the heat pipe. The second telescopic cylinder 211 continues to act to drive the second jaw cylinder 214 holding the heat pipe to approach the CCD camera 223. The CCD camera 223 captures the two-dimensional code image on the heat pipe and transmits the image to the control system for analysis to identify the direction of the heat pipe. After identification is completed, the second jaw cylinder 214 and the fifth jaw cylinder 234 release the heat pipe, and the jacking cylinder 233 is started, and the piston rod is extended to lift the heat pipe from the groove of the receiving rack 232. The material transfer mechanism 7 moves to the receiving rack 232 again, clamps the lifted heat pipe, and sends it to the pushing mechanism 3 for subsequent processing operation. After that, each mechanism is reset, waiting for the next heat pipe identification work. The above-mentioned components cooperate and work together to form a stable automated production system. For example, the second telescopic cylinder 211, the first rotary cylinder 213, the second jaw cylinder 214, the CCD camera 223, the jacking cylinder 233, and the material transfer mechanism 7 act in turn according to the preset program and logical order, ensuring that the heat pipe identification and transfer process is stable and reliable, reducing production interruptions caused by human factors or equipment failures, and improving the stability and continuity of overall production.

[0038] As mentioned above, the second telescopic cylinder 211 provides stable horizontal movement power, enabling the second gripper cylinder 214 to accurately approach the heat pipe on the material receiving rack 232 for grabbing. The precise telescopic control ensures the accuracy of the heat pipe grabbing position, laying the foundation for subsequent adjustment and identification. The first rotary cylinder 213 drives the second gripper cylinder 214 to rotate, and by adjusting the heat pipe flexibly, the two-dimensional code mark on the heat pipe can be quickly and accurately found. This precise adjustment enables the CCD camera 223 to clearly capture the two-dimensional code image, greatly improving the success rate and accuracy of two-dimensional code identification. The fifth gripper cylinder 234 assists in fixing the heat pipe during identification, preventing the heat pipe from moving due to external interference, and ensuring the stability of the heat pipe during identification, thereby improving the reliability of the identification result. The semicircular groove on the material receiving rack 232 provides a stable placement platform for the heat pipe, facilitating the positioning and receiving of the heat pipe. When the heat pipe identification is completed, the jacking cylinder 233 can timely lift the heat pipe from below the material receiving rack 232, making the heat pipe disengage from the groove, and facilitating the quick clamping of the material transfer mechanism 7. The close cooperation between the jacking cylinder 233 and the material transfer mechanism 7 can quickly and accurately transfer the heat pipe from the material receiving rack 232 to the material pushing mechanism after the heat pipe identification is completed, realizing the efficient connection of the heat pipe between two processes, and greatly improving the overall production efficiency.

[0039] As Figure 1 、 Figure 2 、 Figure 5As shown, the pushing mechanism 3 comprises an X-axis linear module 31, and the first base 32 is slidably connected to the X-axis linear module 31. The second rotary air cylinder 33 is installed on the first base 32, and the third jaw air cylinder 34 is connected to the rear end of the second rotary air cylinder 33. In specific implementation, the X-axis linear module 31 generally comprises a lead screw, a slide rail, a motor and the like, which are well known in the art and can be set according to common structures in the art. The X-axis linear module 31 provides a sliding path and power for the first base 32, drives the first base 32 to move linearly along the X-axis direction, and drives the second rotary air cylinder 33 to move along the X-axis direction when the first base 32 moves with the X-axis linear module 31. The third jaw air cylinder 34 can clamp the material transferred by the material transfer mechanism 7, and move on the X-axis linear module 31 to reach the designated position of the bending mechanism 4 to perform the heat pipe bending operation. The first base 32 is slidably connected to the X-axis linear module 31. The second rotary air cylinder 33 is installed on the first base 32, and the first base 32 provides an installation basis and support for the second rotary air cylinder 33. The third jaw air cylinder 34 is connected to the rear end of the second rotary air cylinder 33, and the second rotary air cylinder 33 can drive the third jaw air cylinder 34 to rotate. Through rotation, the angle of the heat pipe clamped by the third jaw air cylinder 34 can be adjusted to meet the needs of subsequent processing.

[0040] In implementation, the material transfer mechanism 7 transfers the heat pipe to a position where the pushing mechanism 3 can clamp it. At this time, the X-axis linear module 31 drives the first base 32 to move, so that the third clamping cylinder 34 approaches the heat pipe. When the third clamping cylinder 34 moves to the position of the heat pipe, the clamping jaw is closed through air pressure control, firmly clamping the heat pipe. If the heat pipe needs to be adjusted in angle before entering the bending mechanism 4, the second rotary cylinder 33 is started to drive the third clamping cylinder 34 to rotate, adjusting the heat pipe to the appropriate posture. The X-axis linear module 31 is started again to drive the first base 32 to move along the X-axis direction, pushing the third clamping cylinder 34 clamping the heat pipe to the specified position of the bending mechanism 4. When the heat pipe reaches the specified position of the bending mechanism 4, the pushing mechanism 3 stops moving. During the whole process of the bending mechanism 4 processing the heat pipe, the third clamping cylinder 34 always maintains a stable clamping state, fixing the heat pipe to assist the bending mechanism 4 to complete accurate bending processing. After the bending mechanism 4 finishes processing, the material transfer mechanism 7 moves to the third clamping cylinder 34 to clamp the heat pipe after bending. Then, the material transfer mechanism 7 lifts the heat pipe to separate it from the bending mechanism 4. At this time, the third clamping cylinder 34 opens the clamping jaw through air pressure control, releasing the heat pipe. Finally, the material transfer mechanism 7 places the clamped heat pipe to the discharging mechanism 5, completing the processing and transfer process of the heat pipe. After that, the X-axis linear module 31 of the pushing mechanism 3 drives the first base 32 to return to the initial position, waiting for the next pushing task.

[0041] As mentioned above, the accurate linear positioning function of the X-axis linear module 31 enables the heat pipe to accurately reach the specified position of the bending mechanism 4, reducing positioning errors and improving the accuracy of bending processing. At the same time, the fast linear movement capability shortens the transfer time of the heat pipe, improving production efficiency. The second rotary cylinder 33 can adjust the angle of the heat pipe, enabling the pushing mechanism 3 to adapt to different bending processes and requirements. For heat pipes of different shapes and specifications, their postures can be adjusted through rotation, expanding the application range of the equipment. The firm clamping function of the third clamping cylinder 34 and the coordination among the components ensure the stability of the heat pipe during the transfer process. This reduces the occurrence of heat pipe falling, shaking, etc., reduces the rate of defective products, and improves the stability and reliability of production.

The left end of the first positioning cylinder 422 is connected with a first positioning die 4221, and the left end of the second positioning cylinder 423 is connected with a second positioning die 4222.

[0043] In specific implementation, the pushing mechanism 3 delivers the heat pipe to the designated position of the bending mechanism 4. At this time, under the action of air pressure, the piston rod of the first positioning cylinder 422 and the second positioning cylinder 423 extends, driving the first positioning die 4221 and the second positioning die 4222 to move towards the heat pipe until they tightly fit the heat pipe, positioning and fixing the heat pipe. According to the specifications of the heat pipe, a semicircular bending wheel 4111 with a suitable diameter is selected to contact the heat pipe. The first motor 413 is started to drive the rotating shaft 412 to rotate. The gear 414 at the lower end of the rotating shaft 412 engages with the worm 415 to transmit the rotary motion to the bending die 411. Under the drive of the first motor 413, the bending die 411 starts to rotate to perform bending operation on the heat pipe. Since the first positioning die 4221 and the second positioning die 4222 have positioned and fixed the heat pipe, the heat pipe remains stable during the bending process, ensuring the accuracy of the bending. After the bending is completed, the first motor 413 stops running and the bending die 411 stops rotating. Under the action of air pressure, the piston rod of the first positioning cylinder 422 and the second positioning cylinder 423 retracts, driving the first positioning die 4221 and the second positioning die 4222 to move away from the heat pipe. At this time, the material transfer mechanism 7 can clamp and transfer the bent heat pipe to the discharging mechanism 5, and then the components are reset for the next bending task.

[0044] As mentioned above, the second positioning device 42 precisely positions and fixes the heat pipe, reducing the displacement and shaking of the heat pipe during the bending process. At the same time, the bending head 41 can realize high-precision bending operation through the transmission of the gear 414 and the worm 415 and the precise control of the first motor 413, improving the bending precision and quality of the product. The bending die 411 is composed of a plurality of semicircular bending wheels 4111 with different diameters, which can adapt to the bending needs of heat pipes of different specifications. This makes the bending mechanism 4 able to handle heat pipes of multiple specifications, increasing the application range of the equipment and reducing the production cost of the enterprise. The first motor 413 can quickly and accurately drive the bending die 411 to perform bending action, while the second positioning device 42 can quickly position and fix the heat pipe. The whole bending process is fully automated, improving the production efficiency.

[0045] Continuing as Figure 1 , Figure 2 , Figure 6As shown, further, the bending mechanism 4 further comprises an XYZ moving device 43 connected to the lower end of the bending head 41 for adjusting the position of the bending head 41. The XYZ moving device 43 is closely connected to the bending head 41, and its main function is to adjust the position of the bending head 41 when facing the production needs of different models of heat pipes. It has higher accuracy and faster adjustment speed. This not only reduces the cost of manual adjustment, but also greatly shortens the adjustment time and improves the production efficiency. The XYZ moving device 43 comprises a first fixed support 431, an X-axis adjusting device 432 connected to the fixed support, and a Y-axis adjusting device 433 connected to the lower end of the bending head 41. The X-axis adjusting device 432 is used to realize the adjustment of the bending head 41 in the X-axis direction, and the Y-axis adjusting device 433 is used to realize the adjustment of the bending head 41 in the Y-axis direction. The first fixed support 431 is detachably connected to the lower end of the installation table 101 to facilitate adjustment in the Z-axis direction, and the detachable connection can be bolted or the like. In specific implementation, since the material pushing mechanism 3 can push the material, the adjustment of the XYZ moving device 43 in the Z-axis direction is not often used in the processing process, so manual adjustment is used when needed. Specifically, the X-axis adjusting device 432 comprises a second adjusting screw 4321 connected to the first fixed support 431 and a second motor 4322 for driving the second adjusting screw 4321 to act. The bending head 41 is slidingly connected to the first fixed support 431, and the front end of the second adjusting screw 4321 is connected to the bending head 41. The second motor 4322 drives the adjusting screw 4321 to rotate, and the screw transmission principle is used to convert the rotary motion of the motor into the linear motion of the bending head 41 in the X-axis direction. The Y-axis adjusting device 433 comprises a lifting guide rod assembly 4331 connected to the lower end of the bending head 41 and a third motor 4332 connected to the lower end of the lifting guide rod assembly 4331. The third motor 4332 drives the lifting guide rod assembly 4331 to act, thereby driving the bending head 41 to move up and down in the Y-axis direction. The lifting guide rod assembly 4331 is a technology known in the art, and the common structure in the art can be referred to for setting.

[0046] When the production line needs to switch to a different type of heat pipe for production, first, according to the model and process requirements of the new heat pipe, determine the target position of the bending machine head 41 in the X, Y, Z three directions that need to be adjusted. If the production of the new heat pipe needs to adjust the position in the Z axis direction, the operator manually disassembles the first fixed support 431, then moves the first fixed support 431 together with the bending machine head 41 in the Z axis direction to the appropriate position, and finally re-fixes the first fixed support 431 on the installation table 101. When the position adjustment in the X axis direction is needed, the control system issues an instruction to start the second motor 4322. The second motor 4322 drives the adjusting screw rod 4321 to rotate, and the adjusting screw rod 4321 converts the rotary motion into linear motion, driving the bending machine head 41 to move along the guide rail of the first fixed support 431 in the X axis direction, until the bending machine head 41 reaches the specified X axis target position. When the position adjustment in the Y axis direction is needed, the control system issues an instruction to start the third motor 4332. The third motor 4332 drives the lifting guide rod assembly 4331 to act, and the lifting guide rod assembly 4331 drives the bending machine head 41 to move up and down in the Y axis direction, until the bending machine head 41 reaches the specified Y axis target position.

[0047] As shown in Figure 1 , Figure 2 , Figure 7 , the linear module 6 includes a second fixed support 61, a linear guide rail 62 mounted on the second fixed support 61, and a driving cylinder 63. The second fixed support 61 is a support component of the linear module 6, providing a mounting basis for the linear guide rail 62 and the driving cylinder 63, and serving to fix and support the entire linear module 6. The linear guide rail 62 is mounted on the second fixed support 61, providing a sliding path for the material transfer mechanism 7, ensuring that the material transfer mechanism 7 can move reciprocally along the linear direction. The driving cylinder 63 is provided with two driving cylinders, respectively arranged at the left end and the right end of the linear guide rail 62. The material transfer mechanism 7 is slidably connected to the linear guide rail 62 and can reciprocally move along the linear guide rail 62 under the drive of the driving cylinder 63. The driving cylinder 63 drives the material transfer mechanism 7 to reciprocally move on the linear guide rail 62 through its own driving force. The driving mode is simple and reliable, with fast response speed, which can quickly and accurately drive the material transfer mechanism 7 to move, improving the production efficiency. At the same time, the arrangement of the two driving cylinders 63 can realize bidirectional driving, making the movement of the material transfer mechanism 7 more flexible.

[0048] Continuing as Figure 1 , Figure 2 , Figure 7As shown, the material transfer mechanism 7 comprises a sliding seat 71 connected to the linear module 6, a third telescopic cylinder 72 connected to the sliding seat 71, a second sliding rail 73 connected to the lower end of the third telescopic cylinder 72, a third rotary cylinder 74 connected to the lower end of the second sliding rail 73, and a fourth clamping jaw cylinder 75 connected to the lower end of the third rotary cylinder 74. An adjusting bolt 76 is arranged between the third telescopic cylinder 72 and the second sliding rail 73. The third telescopic cylinder 72 realizes the vertical lifting of the material transfer mechanism 7 relative to the linear module 6. The third rotary cylinder 74 is used to rotate the heat pipe to the correct direction when the direction identification mechanism 2 identifies that the direction of the heat pipe is incorrect, and is identified again by the direction identification mechanism 2. At the same time, the heat pipe can be clamped and rotated when the bending mechanism 4 completes the bending process, so as to avoid interference between the bent heat pipe and other mechanisms, and facilitate the unloading. Under normal circumstances, the third telescopic cylinder 72 is relatively fixed with the second sliding rail 73. When the positions of the third rotary cylinder 74 and the fourth clamping jaw cylinder 75 need to be adjusted forward and backward, the adjusting bolt 75 can be loosened to adjust the positions, so as to meet the processing requirements of heat pipes of different lengths.

[0049] In the implementation, the linear module 6 drives the sliding seat 71 of the material transfer mechanism 7 to move to the feeding mechanism. The third telescopic cylinder 72 extends the piston rod, and the fourth gripper cylinder 75 is lowered to an appropriate height, close to the heat pipe on the feeding mechanism 1. The fourth gripper cylinder 75 is started, the gripper is closed, and the heat pipe is firmly clamped. Then, the third telescopic cylinder 72 retracts the piston rod, and the heat pipe is lifted to a certain height. The linear module 6 continues to drive the material transfer mechanism 7 to move to the direction identification mechanism 2. The third telescopic cylinder 72 extends the piston rod, and the heat pipe is placed on the direction identification mechanism 2. The fourth gripper cylinder 75 releases the heat pipe. The direction identification mechanism 2 identifies the direction of the heat pipe. If the direction of the heat pipe is incorrect, the fourth gripper cylinder 75 clamps the heat pipe again, the third rotary cylinder 74 is started, and the heat pipe is rotated to the correct direction. The direction identification mechanism 2 identifies again until the direction is correct. After confirming that the direction of the heat pipe is correct, the third telescopic cylinder 72 retracts the piston rod, and the linear module 6 drives the material transfer mechanism 7 to move to the pushing mechanism 3. The third telescopic cylinder 72 extends the piston rod, and the heat pipe is placed on the pushing mechanism 3. The fourth gripper cylinder 75 releases the heat pipe. The pushing mechanism 3 transports the heat pipe to the bending mechanism 4 for bending processing. In this process, the material transfer mechanism 7 waits for the bending processing to be completed. After the bending mechanism 4 completes the bending processing, the third telescopic cylinder 72 extends the piston rod to clamp the processed material on the pushing mechanism 3, and the fourth gripper cylinder 75 clamps the bent heat pipe. If the bent heat pipe may interfere with other mechanisms, the third rotary cylinder 74 is started to rotate the heat pipe to avoid interference. Then, the third telescopic cylinder 72 retracts the piston rod, and the linear module 6 drives the material transfer mechanism 7 to move to the discharging mechanism 5. The third telescopic cylinder 72 extends the piston rod, and the fourth gripper cylinder 75 releases the bent heat pipe and places it on the discharging mechanism.

[0050] As shown in Figure 1 、 Figure 2 The discharging mechanism 5 includes a conveyor belt 51, a discharging chute 52, and a fourth motor 53 for driving the conveyor belt 51. This is a well-known technology in the art, and those skilled in the art can refer to the corresponding structure in the prior art for design, so it is not necessary to describe it in detail.

[0051] As described above, the present application protects an automatic bending machine, and all technical solutions similar or similar to the present application should be shown to fall within the scope of protection of the present application.
