However, the heat pipe shrinking device in the prior art can only shrink the head or tail of the heat pipe separately, and cannot shrink the head and tail of the heat pipe at the same time, which affects the production efficiency of the heat pipe. Usually, the shrinking of the head and tail of the heat pipe requires two discharge and collection operations, and the above-mentioned collection and discharge processes need to be implemented through manual operation, which reduces the degree of automation of the entire equipment and affects the production efficiency of the heat pipe.

[0015] The sprocket drive motor is connected to the material receiving disc and the two driving sprockets respectively to synchronously drive the material receiving disc and the two driving sprockets.

[0016] Wherein, the side wall of the receiving disc is axially provided with at least one V-groove for receiving the heat pipe to be processed, and the chain is arranged in a V-shaped opening.

[0034] Unlike existing heat pipe conveyor devices, which require multiple steps and a low degree of automation when shrinking both ends, thus affecting heat pipe production efficiency, the present invention provides a new heat pipe conveyor device that can simultaneously shrink heat pipes at both ends, achieving a high degree of automation and improving heat pipe production efficiency. The specific structure of this heat pipe conveyor device is described in the following embodiments.

[0035] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a heat pipe transport device according to an embodiment of the present invention. In this embodiment of the present invention, the heat pipe transport device includes:

[0036] A silo assembly 100 having a discharge port;

[0037] A chain conveyor track 200, one end of which is arranged corresponding to the discharge port of the silo assembly 100, so as to convey the heat pipe to be processed to the preset clamping position and convey the shrunk heat pipe to the blanking position;

[0038] A positioning and clamping mechanism 300 is located above the chain conveyor track 200 to move the heat pipe to be processed at a preset clamping position to the processing station, simultaneously positioning and clamping the heat pipe to be processed, and returning the shrunk heat pipe to the preset clamping position of the chain conveyor track 200;

[0039] Two retracting mechanisms 410 and 420 are disposed opposite to each other and are respectively close to the two sides of the positioning and clamping mechanism 300 to retract the head and tail of the heat pipe to be processed;

[0040] The material box 500 is located below the material drop position of the chain conveyor track 200 to collect the shrunk heat tubes.

[0041] Specifically, the above-mentioned chain conveyor track 200, positioning and clamping mechanism 300, two retraction mechanisms 410, 420 and material box 500 are all arranged on the frame 600. The above-mentioned silo assembly 100 is located above the chain conveyor track 200. The silo assembly 100 has a storage space for accommodating and arranging the heat pipes to be processed, and a discharge port located below the storage space. The discharge port can discharge the heat pipes to be processed one by one to facilitate processing. The heat pipes to be processed coming out of the discharge port directly enter the chain conveyor track 200 and are automatically transported to the preset clamping position. The positioning and clamping mechanism 300 can move the heat pipe to be processed located at the preset clamping position to the processing station, and at the same time position and clamp the heat pipe to be processed. The two retraction mechanisms 410, 420 can respectively retract the head and tail of the heat pipe to be processed. After shrinking, the shrunk heat pipe is obtained. The positioning and clamping mechanism 300 drives the shrunk heat pipe back to the preset clamping position, and the chain conveyor track 200 continues to transport it to the blanking position. Finally, the shrunk heat pipe can be collected in the material box 500. In this way, both the head and the tail of the heat pipe can be shrunk, and the entire heat pipe shrinking process can be completed.

[0042] Please refer to Figure 2 , Figure 2 Schematic diagram of the structure of the chain conveyor track 200 of the present invention. In a specific embodiment, the chain conveyor track 200 includes:

[0043] A fixed side track 211 and a movable side track 212 , wherein the fixed side track 211 and the movable side track 212 are arranged opposite to each other and the track width between the fixed side track 211 and the movable side track 212 is adjustable;

[0044] Two sprocket transmission assemblies, the two sprocket transmission assemblies are respectively installed on the inner sides of the fixed side track 211 and the movable side track 212, and the sprocket transmission assemblies include a driving sprocket 221, a driven sprocket 222, and a chain 223 wound around the driving sprocket 221 and the driven sprocket 222;

[0045] The receiving disc 230 is located between the two driving sprockets 221 and is coaxial with the two driving sprockets 221;

[0046] The sprocket drive motor 240 is connected to the material receiving disc 230 and the two driving sprockets 221 respectively to synchronously drive the material receiving disc 230 and the two driving sprockets 221.

[0047] In this embodiment, the movable side rail 212 can be adjusted appropriately based on the length and specifications of the heat pipes being processed to accommodate the production of heat pipes of varying specifications. The positioning and clamping mechanism 300 is located between the fixed side rail 211 and the movable side rail 212. The receiving disc 230 is positioned near the discharge port and rotates under the drive of the sprocket drive motor 240. During this rotation, it receives the heat pipe to be processed from the discharge port and conveys it to the chain 223.

[0048] Furthermore, the sidewall of the receiving disc 230 is axially provided with at least one V-groove 231 for receiving the heat pipe to be processed, ensuring stable reception. The number of V-grooves 231 can be adjusted according to actual requirements. Accordingly, the chain 223 is configured with a V-shaped opening 2231, which also provides stable support for the heat pipe and prevents it from slipping off the chain 223. The heat pipe is primarily driven by a sprocket drive assembly, which includes a driving sprocket 221, a driven sprocket 222, and a chain 223 wound around the driving sprocket 221 and the driven sprocket 222. A sprocket drive motor 240 provides rotational power for the driving sprocket 221 and the receiving disc 230. This sprocket drive motor 240 can be a controllable reduction motor, the output end of which is connected to a power transmission hexagonal rod 241, which synchronously drives the two driving sprockets 221 and the receiving disc 230. In this embodiment, the fixed side rail 211 , the movable side rail 212 and the two sprocket transmission components can ensure the reliability of heat pipe transportation and further improve production efficiency.

[0049] Furthermore, the chain conveyor track 200 also includes: two blanking guide plates 250 respectively installed on the fixed side track 211 and the movable side track 212 and close to the driven sprocket, and the free ends of the blanking guide plates 250 are inclined toward the direction of the material box 500.

[0050] In this embodiment, the shrunk heat pipe slides into the material box 500 through the two blanking guide plates 250, which reduces the height of the shrunk heat pipe and prevents it from falling directly into the material box 500, making the heat pipes in the material box 500 more neat.

[0051] Furthermore, the chain conveyor track 200 also includes: a track width adjustment rod 270 that passes through the fixed side track 211 and the movable side track 212 and is used to adjust the distance between the movable side track 212 and the fixed side track 211, and a handle 260 fixed to one end of the track width adjustment rod 270 and is used to rotate the track width adjustment rod 270.

[0052] In this embodiment, the track width adjustment rod 270 can be rotated through the handle 260. The part of the track width adjustment rod 270 close to the handle 260 is slidingly connected to the fixed side rail 211, and the part of the track width adjustment rod 270 close to the handle 260 is threadedly connected to the movable side rail 212. In this way, when the handle 260 is rotated, the position of the track width adjustment rod 270 and the fixed side rail 211 remains unchanged, while it moves relative to the movable side rail 212, thereby adjusting the width of the fixed side rail 211 and the movable side rail 212 to meet the requirements of different heat pipe lengths.

[0053] Please refer to Figure 3 , Figure 3 Schematic diagram of the structure of the silo assembly 100 of the present invention. In a specific embodiment, the silo assembly 100 includes a silo body 101, a slide bar 102 installed in the silo body 101 and arranged horizontally along the silo body 101, and a tube length limit plate 103 installed on the slide bar 102 and slidable along the length direction of the slide bar 102. In this embodiment, the tube length limit plate 103 can slide on the slide bar 102 to limit the length of the heat pipe. It is understandable that a positioning block can also be provided on the tube length limit plate 103 to locate the position of the tube length limit plate 103.

[0054] Furthermore, the silo assembly 100 also includes a pipe diameter adjustment plate 104 installed in the silo body 101 and slidable along the flow direction of the chain conveyor track 200. In this embodiment, the pipe diameter adjustment plate 104 can move longitudinally along the silo body 101, that is, move along the conveying direction of the chain track, to limit the diameter of the heat pipe. By setting the pipe diameter adjustment plate 104 and the pipe length limiting plate 103, the heat pipes in the silo assembly 100 can be sorted to facilitate discharge. It is understandable that the pipe diameter adjustment plate 104 can also be provided with a positioning block to locate the position of the pipe diameter adjustment plate 104.

[0055] Furthermore, the discharge port is located at the bottom of the silo body 101 , and the portion of the heat pipe to be processed in the silo body 101 that is about to be discharged is exposed to the discharge port, and the discharge port of the silo body 101 is tangent to the receiving disc 230 .

[0056] In this embodiment, the silo body 101 contains stacked heat pipes to be processed, and the bottom portion of the heat pipe to be processed is exposed from the discharge port and abuts the receiving disc 230. The receiving disc 230 has a V-groove 231 for accommodating a single heat pipe. When the receiving disc 230 rotates to a set position, the V-groove 231 of the receiving disc 230 can accommodate the heat pipe to be processed.

[0057] Please refer to Figure 4 , Figure 4FIG2 is a schematic diagram of the structure of the positioning and clamping mechanism 300 of the present invention. In a specific embodiment, the positioning and clamping mechanism 300 includes an upper positioning module 310 and a lower positioning module 320 clamped with the upper positioning module 310. The lower positioning module 320 is located directly below the upper positioning module 310 and is vertically movable to close or separate from the upper positioning module 310.

[0058] In this embodiment, the positioning and clamping mechanism 300 is divided into an upper positioning module 310 and a lower positioning module 320. The upper positioning module 310 is fixed to the frame 600, wherein the lower positioning module 320 can move vertically and then close or separate with the upper positioning module 310. Specifically, when the heat pipe to be processed is transported to the preset clamping position by the chain conveyor track 200, the lower positioning module 320 drives the heat pipe to be processed to rise together under the action of the cylinder and closes with the upper positioning module 310. At this time, the upper positioning module 310 and the lower positioning module 320 can clamp and position the heat pipe to be processed to prevent the heat pipe to be processed from rotating. After both ends of the heat pipe to be processed are shrunk, the lower positioning module 320 is separated from the upper positioning module 310, and the shrunk heat pipe falls back to the preset clamping position under the action of its own weight, and flows out under the action of the chain conveyor track 200 and falls into the material box 500.

[0059] Specifically, the lower positioning module 320 includes a lower positioning block 321 and a lifting cylinder 322 located below and connected to the lower positioning block 321. The lifting cylinder 322 pushes the lower positioning block 321 toward or away from the upper positioning module 310. In this embodiment, the lifting cylinder 322 can lift the lower positioning block 321, driving the lower positioning block 321 to move up and down. It is understood that the lifting cylinder 322 can also be replaced with a device that provides vertical thrust, such as a drive motor.

[0060] Specifically, the upper positioning module 310 includes a fixing block 311 fixed to the frame 600, and an upper positioning block 312 connected to the fixing block 311 and located above the lower positioning block 321. In this embodiment, the fixing block 311 is fixed to the frame 600, and the upper positioning block 312 is connected to the fixing block 311 and located above the lower positioning block 321, achieving a clamping fit between the two.

[0061] Specifically, the lower positioning block 321 has a first clamping portion on one side near the upper positioning block 312, and the upper positioning block 312 has a second clamping portion that mates with the first clamping portion. Specifically, the first clamping portion has a first notch, and the second clamping portion has a second notch that mates with the first notch. The concave surfaces of both the first and second notches are smooth to prevent damage to the heat pipe.

[0062] Specifically, the two retracting mechanisms 410 and 420 are respectively the first retracting mechanism 410 and the second retracting mechanism 420, which are respectively located on opposite sides of the positioning and clamping mechanism 300. During processing, the positioning and clamping mechanism 300 clamps the middle position of the heat pipe to be processed, and the tube head and tube tail of the heat pipe to be processed both extend out of the positioning and clamping mechanism 300. It can be understood that the extension length of the tube head and tube tail of the heat pipe to be processed can be flexibly set according to specific requirements, and there is no restriction here. At this time, the extension length of the tube head and tube tail of the heat pipe to be processed can be retracted by using the first retracting mechanism 410 and the second retracting mechanism 420. During actual processing, the tube tail of the heat pipe to be processed is first retracted by using the first retracting mechanism 410, and then the tube head of the heat pipe to be processed is retracted by using the second retracting mechanism 420. In this way, the two ends of the heat pipe to be processed can be retracted at one time.

[0063] Please refer to Figure 5 , Figure 5 The heat pipe retraction mechanism of the present invention is schematically shown. Specifically, the retraction mechanism includes a slide 411, a retraction drive motor 412 disposed on the slide 411, and a retraction assembly 413 connected to the retraction drive motor 412 for retracting the heat pipe head or tail to be processed.

[0064] In this embodiment, the slide 411 is located on the frame 600, adjacent to and separated from the positioning and clamping mechanism 300. The retraction drive motor 412 is specifically a high-speed rotary motor. The retraction assembly 413 is specifically a head retraction assembly or a tail retraction assembly having the same structure. The retraction drive motor 412 can drive the head retraction assembly to retract the head of the heat pipe to be processed; or the retraction drive motor 412 can drive the tail retraction assembly to retract the tail of the heat pipe to be processed.

[0065] Specifically, the slide 411 is slidably connected to the frame 600 and can move toward or away from the positioning and clamping mechanism 300. Considering the distance between the slide 411 and the positioning and clamping mechanism 300, when rotating and shrinking the head or tail of the heat pipe, the slide 411 can be moved a certain distance toward the positioning and clamping mechanism 300 to rotate and shrink the head or tail of the heat pipe to be processed.

[0066] Furthermore, the present invention further includes a motor 601 disposed on the frame 600, and a screw rod 602 having one end in transmission connection with the motor 601 and the other end in movably connected to the slide 411. The motor 601 drives the screw rod 602 to rotate, so that the screw rod 602 and the slide 411 move relative to each other. Specifically, the screw rod 602 and the slide 411 rotate in coordination, and when the motor 601 is operating, the screw rod 602 is driven to rotate, thereby causing the screw rod 602 and the slide 411 to move relative to each other, thereby moving the slide 411 toward or away from the positioning and clamping mechanism 300. In order to better achieve the relative movement of the screw rod 602 and the slide 411, the slide 411 can also be slidably disposed on the frame 600, so that the slide 411 slides in a directional manner and reduces the resistance to the movement of the slide 411.

[0067] Specifically, the retraction mechanism also includes a slide cylinder 414 provided on the slide 411, and a fixed-length plate 415 connected to the slide cylinder 414. The slide cylinder 414 drives the fixed-length plate 415 to move vertically to resist or avoid the heat pipe to be processed.

[0068] During processing, this solution first uses the first shrinking mechanism 410 to shrink the tail of the heat pipe to be processed, and then uses the second shrinking mechanism 420 to shrink the head of the heat pipe to be processed. When the first shrinking mechanism 410 is used to shrink the tail of the heat pipe to be processed, the slide cylinder 414 of the second shrinking mechanism 420 moves the fixed-length plate 415 so that the fixed-length plate 415 abuts the head of the heat pipe to be processed, thereby preventing the heat pipe to be processed from sliding axially toward the head, thereby improving the reliability of processing. Similarly, when the second shrinking mechanism 420 is used to shrink the head of the heat pipe to be processed, the slide cylinder 414 of the first shrinking mechanism 410 moves the fixed-length plate 415 so that the fixed-length plate 415 abuts the tail of the heat pipe to be processed, thereby preventing the heat pipe to be processed from sliding axially toward the tail.

[0069] In an embodiment of the present invention, the necking device includes the aforementioned heat pipe transport device. The specific structure of the heat pipe transport device is described in the aforementioned embodiment and will not be further described here. Because the necking device of this embodiment utilizes the aforementioned heat pipe transport device, it possesses all the advantages and effects of the heat pipe transport device.

[0070] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings under the technical solution of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
