[0002] With the rapid development of science and technology, electronic products such as mobile phones, tablet computers, and car computers are developing towards high-density integration and ultra-precision. The heat dissipation performance of electronic products has become increasingly important. Therefore, the requirements for the processing accuracy of radiators used in electronic products are becoming higher and higher. This involves rounding the large and small ends of special heat pipes with a certain length and different diameters in order to complete subsequent water injection, tail shrinkage, and sealing operations. Since the heat pipe is a precision component, its tube wall is relatively thin, the copper tube body is easy to deform and difficult to position, and the water injection amount must be strictly controlled within the required numerical range. Therefore, the straightness, roundness, and flatness of the heat pipe body before water injection are directly related to whether the subsequent manufacturing process can be successfully completed.

[0026] In order to explain the content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0027] See also Figure 1 , Figure 2 and Figure 4The present invention discloses a feeding rounding machine 100, which is suitable for rounding and shaping a heat dissipation pipe 200 before water injection. In the present application, the heat dissipation pipe 200 is specifically a part of a radiator used in electronic products such as mobile phones, tablet computers, and car computers. The heat dissipation pipe 200 is a copper pipe with a certain length, which is approximately 280-330 mm in length, and is generally tubular in shape, and has a large end 201 and a small end 202 of different diameters. In this machine, the large end 201 with a relatively large diameter and the small end 202 with a relatively small diameter are not sealed, and the port of the small end 202 is a subsequent water injection port, which is approximately 3-4 mm in diameter.

[0028] See also Figure 1 , Figure 2 and Figure 4 The loading and rounding machine 100 provided in the preferred embodiment of the present invention includes a loading device 10 and a unloading device 40 arranged at intervals on the front and rear opposite sides of a working platform 101, a rounding device 30 arranged between the loading device 10 and the unloading device 40, and a positioning device 20 arranged between the loading device 10 and the rounding device 30. The feeding device 10 can make linear reciprocating motion along the X-axis, Y-axis and Z-axis directions relative to the positioning device 20, and is used to transfer the heat dissipation tubes 200 arranged evenly on the material tray 300 of the feeding device 10 to the positioning device 20 in sequence. The positioning device 20 is used to receive the heat dissipation tubes 200 transferred by the feeding device 10, adjust the placement of the heat dissipation tubes 200, and also transmit the adjusted heat dissipation tubes 200 toward the direction of the rounding device 30. The rounding device 30 is used to receive the heat dissipation tubes 200 transmitted by the positioning device 20, and can make linear motion close to or away from the heat dissipation tubes 200, so as to synchronously round the large end 201 and the small end 202 of the heat dissipation tubes 200 of different diameters. The unloading device 40 can make linear reciprocating motion relative to the rounding device 30, and is used to take out the rounded heat dissipation tubes 200 from the rounding device 30 and transfer them for unloading.

[0029] Of course, the feeding and rounding machine 100 of the present invention also includes a controller, which is electrically connected to the feeding device 10, the positioning device 20, the rounding device 30 and the unloading device 40, and is used to control the coordinated actions between the devices. Among them, the controller is an existing design, and its structure and control principle are well known in the art, so it is not described in detail here. Specifically, in a preferred embodiment of the present invention, the feeding device 10 can synchronously transfer at least two heat pipes 200 to the positioning device 20 each time, and correspondingly, the positioning device 20 adjusts the placement position of at least two heat pipes 200 each time, the rounding device 30 performs rounding and shaping on at least two heat pipes 200 each time, and the unloading device 40 transfers and discharges at least two heat pipes 200 each time, thereby improving production efficiency.

[0030] See also Figures 1 to 4Specifically, in this embodiment, the loading device 10 includes a feeding mechanism 11 and a loading mechanism 12 mounted between the feeding mechanism 11 and the positioning device 20. The feeding mechanism 11 is used to separate the stacked multiple trays 300 one by one to a position convenient for the loading mechanism 12 to take the material. The loading mechanism 12 can make a linear reciprocating motion relative to the feeding mechanism 11, and is used to sequentially transfer the heat dissipation pipes 200 arranged equidistantly on each tray 300 to the positioning device 20. Among them, the feeding mechanism 11 includes a material box 111, a full tray conveyor line 112 and an empty tray conveyor line 113 arranged in parallel and spaced apart at the bottom and top of the material box 111, and a lifting platform 114 located between the output end of the full tray conveyor line 112 and the input end of the empty tray conveyor line 113. The input end of the empty tray conveyor line 113 is provided with a clamping assembly 115, and the output end of the empty tray conveyor line 113 is provided with a support plate 116. The trays 300 filled with heat dissipation tubes 200 are stacked on the full tray conveyor line 112 and are moved by the full tray conveyor line 112 from the input end thereof to the output end thereof to approach the lifting platform 114. The lifting platform 114 can lift the stacked trays 300 at the output end of the full tray conveyor line 112 upward along the Z-axis direction until they are close to the position of the clamping assembly 115. Under the cooperation of the clamping force applied by the clamping assembly 115 to the outer side of the tray 300 on the top layer and the downward moving force of the lifting platform 114 on the remaining trays, the trays 300 on the top layer are lifted upward along the Z-axis direction. The material tray 300 on the top layer is separated from the entire stack of material trays 300 to wait for material retrieval; when material retrieval is completed, the empty tray conveyor line 113 drives the clamping assembly 115 to carry the empty material tray 300 toward its output end, and combined with the support plate 116, it can move linearly along the Z-axis direction, thereby lifting the empty material tray 300 to the material receiving frame 117 supported on the support plate 116; by repeating the above operations continuously, the uninterrupted feeding of the heat dissipation tube 200 can be achieved, and the empty material trays 300 are stacked in the material receiving frame 117 from bottom to top.

[0031] See also Figure 4Specifically, in the present embodiment, a plurality of first tooth-shaped structures 301 and a second tooth-shaped structure 302 are arranged in parallel and spaced apart along the longitudinal direction of the material tray 300. The first tooth-shaped structure 301 has a plurality of first tooth grooves 311 equidistantly arranged along the transverse width direction of the material tray 300, and the second tooth-shaped structure 302 has a plurality of second tooth grooves 3021 equidistantly arranged along the transverse width direction of the material tray 300. The first tooth grooves 311 and the second tooth grooves 3021 are arranged in a one-to-one correspondence, and a position for accommodating the heat dissipation pipe 200 is formed between the plurality of first tooth grooves 311 and the second tooth groove 3021 arranged in a straight line along the longitudinal direction of the material tray 300. Therefore, a plurality of positions can be provided on a material tray 300, so that a plurality of heat dissipation pipes 200 can be accommodated, thereby effectively improving the feeding efficiency. Among them, the large end 201 of a heat dissipation pipe 200 is clamped in the first plurality of tooth grooves 311 of the corresponding clamping position, and the small end 202 thereof is clamped in the second tooth groove 3021. When heat dissipation pipes 200 of different lengths are placed in the material tray 300, only the length of the small end 202 of each heat dissipation pipe 200 beyond the second tooth groove 3021 is different, thereby effectively improving the versatility of the material tray 300. Preferably, the cross-sectional shape of the first tooth groove is "V" shaped, and the cross-sectional shape of the second tooth groove is "V" shaped, "Y" shaped or "U" shaped, thereby adapting to the placement of heat dissipation pipes 200 of different diameters, further improving the versatility of the material tray 300.

The X-axis driver 122, the Y-axis driver 123, the Z-axis driver 124 and the Z-axis driver 125 correspondingly drive the two clamping members 127 to reciprocate linearly along the X-axis, Y-axis and Z-axis directions to travel back and forth between the feeding mechanism 11 and the positioning device 20, so that the clamping member 127 is driven by the clamping driver 126 to pick up and deliver the heat dissipation tube 200. X-axis driver 122, Y-axis driver 123, Z-axis driver 124 and Z-axis driver 125 can all use linear motors, clamping driver 126 uses linear cylinders, and clamping member 127 uses pneumatic clamps. Among them, the clamping member 127 has a clamping surface corresponding to the shape of the heat pipe 200, and the shape of the clamping surface is "V"-shaped, so that it can be compatible with the clamping operation of heat pipes 200 of different diameters. A flexible buffer layer is also provided on the clamping surface of the clamping member 127 abutting against the heat pipe 200, so as to better protect the heat pipe 200. Preferably, the number of clamping members 127 is two, so that the picking and delivery operation of two heat pipes 200 can be realized each time, effectively improving the feeding efficiency.

[0033] See also Figure 6 The positioning device 20 includes a receiving platform 21, a positioning mechanism 22 arranged at the front side of the receiving platform 21, and a supporting mechanism 23 arranged at the lower side of the receiving platform 21. The receiving platform 21 is provided with a plurality of positioning seats 211 arranged in parallel and equidistantly for receiving the heat pipe 200. The positioning mechanism 22 can move linearly toward or away from the receiving platform 21 to push the heat pipe 200 along the X-axis direction, thereby adjusting the placement position of the heat pipe 200 in the positioning seat 211. The supporting mechanism 23 can move linearly along the Z-axis direction and the Y-axis direction relative to the receiving platform 21 to support and transfer the adjusted heat pipe 200 to the positioning seat 211 opposite to the rounding device 30. Specifically, the positioning seat 211 is in a "concave" shape as a whole, and a clamping space is formed between the protruding parts 2111 on both sides and the main body 2112, which is convenient for the placement and delivery of the heat pipe 200. The protrusions 2111 on both sides are provided with placement grooves 211 a in a one-to-one correspondence. The cross-sectional shape of the placement grooves 211 a is “V”-shaped, so as to be compatible with the placement of the large ends 201 of the heat dissipation pipes 200 of different diameters.

[0034] Specifically, the alignment mechanism 22 includes a positioning base 221 and a push plate 222 arranged at two opposite sides of the front end of the receiving platform 21 at intervals along the X-axis direction. The positioning base 221 is made of POM material, and a positioning groove 221a is provided on the positioning base 221. The cross-sectional shape of the positioning groove 221a is "V"-shaped, "Y"-shaped or "U"-shaped, which can adapt to the placement of the small end 202 of the heat dissipation pipe 200 of different diameters, and effectively improve the versatility of the positioning base 221. The push plate 222 can move linearly along the X-axis direction under the drive of the push driver 223 connected thereto, thereby pushing the heat dissipation pipe 200 on the positioning base 211 to adjust the length of the small end 202 of the heat dissipation pipe 200 extending out of the positioning groove 221a of the positioning base 221, thereby realizing the adjustment of the placement position of the heat dissipation pipe 200 on the positioning base 211. The positioning base 221 can move linearly along the Z-axis direction and the X-axis direction under the drive of the jacking driver 224 and the pushing driver 225 connected thereto, so as to adapt to the alignment of the small ends 202 of the heat dissipation pipes 200 of different diameters and lengths. Specifically, in this embodiment, there is one push plate 222 and two positioning bases 221. One push plate 222 can simultaneously adjust the positions of the two heat dissipation pipes 200 on the two positioning bases 221, thereby effectively improving the alignment efficiency.

[0035] Specifically, the supporting mechanism 23 includes two brackets 231 which are symmetrically arranged on two opposite sides of the receiving platform 21 along the X-axis direction. The two brackets 231 are respectively connected to the output end of a lifting driver 232 located on the lower side of the receiving platform 21. The lifting driver 232 is connected to the output end of a transfer driver 233. The two brackets 231 can move linearly along the Z-axis direction under the drive of the lifting driver 232, so that they can move up to support the aligned heat dissipation tube 200 to be separated from the positioning seat 211. The two brackets 231 can also move linearly along the Y-axis direction under the drive of the transfer driver 233 to transfer the supported heat dissipation tube 200 to the positioning seat 211 close to the rolling device 30, thereby facilitating the rolling device 30 to take the material. The two brackets 231 are provided with brackets 231a corresponding to the placement grooves 211a of the positioning seat 211, and the cross-sectional shape of the brackets 231a is "V"-shaped, so as to adapt to the support of heat pipes 200 of different diameters. The number of brackets 231a on each side of the bracket 231 is at least two, so that at least two heat pipes 200 can be supported each time, effectively improving the transfer efficiency.

The rotating mechanism 24 can make a linear movement close to or away from the receiving platform 21 to clamp the heat dissipation tube 200 and drive the heat dissipation tube 200 to rotate. The line scan camera 25 identifies the straightness, roundness and flatness of the tube body of the rotating heat dissipation tube 200. Specifically, the rotating mechanism 24 includes a positioning base 241 and a rotating member 242 arranged at two opposite sides of the receiving platform 21 at intervals along the X-axis direction. The positioning base 241 is made of POM material. A positioning groove 241a is provided on the positioning base 241. The cross-sectional shape of the positioning groove 241a is "V"-shaped, "Y"-shaped or "U"-shaped, which can adapt to the placement of the small end 202 of the heat dissipation tube 200 of different diameters, effectively improving the versatility of the positioning base 241. The rotating member 242 is connected to the output end of the clamping driver 243, the clamping driver 243 is connected to the output end of the rotating driver 244, the rotating driver 244 is connected to the output end of the transfer driver 245, and the rotating member 242 can be driven by the transfer driver 245 to move linearly along the X-axis direction to approach or move away from the heat dissipation pipe 200 placed on the positioning seat 211 and the positioning base 241, so that the large end 201 of the heat dissipation pipe 200 can be inserted into the plug-in slot of the rotating member 242, and the rotating member 242 can also be moved in the clamping position. The heat pipe 200 inserted into the plug slot is clamped or released under the driving of the holding driver 243, so that the heat pipe 200 is driven to rotate relative to the positioning seat 211 and the positioning base 241 under the driving of the rotating driver 244, generally rotating 360° at a constant speed, so that the line scanning camera 25 can identify the straightness, roundness and flatness of the rotating heat pipe 200, and feed the identification information back to the controller, so as to detect whether there are obvious unevenness, obvious scratches and dirt on the pipe body. Among them, the positioning base 241 can also be driven by the lifting driver 246 connected thereto to move linearly along the Z-axis direction to adapt to the alignment of the small end 202 of the heat pipe 200 of different diameters. Specifically, in this embodiment, the positioning base 241 and the rotating member 242 are arranged in a one-to-one correspondence, and the number of both is two. A rotating driver 244 drives two clamping drivers 243 to drive two rotating members 242 to rotate through a synchronous belt, so that the two positioning seats 211 and the two heat dissipation pipes 200 on the corresponding positioning base 241 can be rotated at the same time each time to detect their pipe bodies. The clamping driver 243 is specifically a cylinder, the rotating driver 244 is a rotating motor, and the transfer driver 245 and the lifting driver 246 are linear motors.

[0037] Specifically, in the preferred embodiment of the present invention, 6 positioning seats 211 are evenly distributed on the receiving platform 21, and the 6 positioning seats 211 arranged in sequence form three workstations on the receiving platform 21. The first two positioning seats 211 cooperate with the alignment mechanism 22 to adjust the alignment of the heat dissipation tube 200, and the middle two positioning seats 211 cooperate with the rotation mechanism 24 to detect whether there are obvious defects in the tube body of the heat dissipation tube 200. The last two positioning seats 211 are used to cooperate with the rounding device 30 to facilitate the rounding device 30 to take the material. The number of brackets 231a on each side of the bracket 231 is 4, so that the heat dissipation tubes 200 are transported in groups of two between the three workstations.

Among them, the heat dissipation pipe 200 with obvious defects detected in the positioning device 20 is transferred by the feeding mechanism 32 to the defective product collection box 326 located at the front side end of the rolling table 31. Specifically, in this embodiment, the number of the feeding clamps 325 is two, and two heat dissipation pipes 200 can be simultaneously transferred to the rolling table 31, thereby effectively improving the transmission efficiency. The feeding clamps 325 are specifically pneumatic clamps, the clamping driver 324 is specifically a cylinder, the X-axis driver 321 and the Y-axis driver 322 use linear motors, and the Z-axis driver 323 uses a linear cylinder.

[0040] See also Figure 7 and Figure 8The rolling mechanism 33 includes a first Z-axis driver 331 installed at the top of the frame 102, a substrate 332 connected to the output end of the first Z-axis driver 331, a Y-axis driver 333 installed at the relative center of the substrate 332, a sliding plate 334 slidably inserted on the substrate 332 and connected to the output end of the Y-axis driver 333, a first pressing plate 335 connected to the lower end of the sliding plate 334 below the substrate 332, a second Z-axis driver 336 installed at the opposite side end of the substrate 332, and a second pressing plate 337 slidably connected to the output end of the second Z-axis driver 336 at the lower side of the first pressing plate 335. The first Z-axis driver 331 is used to drive the substrate 332 to move linearly along the Z-axis direction relative to the rolling table 31, thereby driving the first pressing plate 335 and the second pressing plate 337 to move downward synchronously until the first pressing plate 335 abuts against the large end 201 of the heat dissipation tube 200 on the rolling table 31. The second Z-axis driver 336 is used to drive the second pressing plate 337 to continue to move linearly along the Z-axis direction relative to the first pressing plate 335 to abut against the small end 202 of the heat dissipation tube 200. The Y-axis driver 333 is used to drive the sliding plate 334 to move linearly along the Y-axis direction relative to the rolling table 31, thereby driving the first pressing plate 335 and the second pressing plate 337 to synchronously roll the corresponding large end 201 and small end 202 to achieve the rounding shaping of the heat dissipation tube 200 with a certain length and different diameters. A pad can be arranged at the position of the rolling table 31 corresponding to the small end 202 to compensate for the height difference between the small end 202 and the receiving surface of the rolling table 31 due to the unequal diameters, thereby providing a supporting force during rolling to achieve a better shaping effect.

[0041] More specifically, the base plate 332, the first pressing plate 335 and the second pressing plate 337 are all square plates, which are arranged in parallel and spaced apart, and arranged from top to bottom according to the size of the area. The first Z-axis driver 331 is connected to the base plate 332 through a connecting frame 3311 connected to its output end. The connecting frame 3311 is roughly in an inverted "Y" shape. Four linear guides 1021 arranged along the Z-axis direction are also provided on the frame 102 on the peripheral side of the base plate 331. The four top corner ends of the base plate 331 are slidably arranged on the four linear guides 1021 one by one, so as to move smoothly, so that the first pressing plate 335 applies force evenly against the large end 201. Two linear guides 3321 are symmetrically arranged on both sides of the Y-axis driver 333 on the base plate 332, and the linear guides 3321 are arranged on the base plate 332 along the Y-axis direction. The sliding plate 334 is generally in the shape of an "n", and includes a connecting arm 3341 arranged along the X-axis direction and two side arms 3342 connected to the two side ends of the connecting arm 3341 and arranged along the Z-axis direction. The two side arms 3342 pass through the through-slots of the base plate 332 and are connected to the first pressing plate 335 below the base plate 332. The connecting arm 3341 is slidably disposed on two linear guide rails 3321 and is connected to the output end of the Y-axis driver 333. A linear guide rail 3371 arranged along the Y-axis direction is provided between the base plate 332 and the first pressing plate 335. The second pressing plate 337 is connected to the linear guide rail 3371 through a guide rod 3372 passed through the first pressing plate 335 along the Z-axis direction. The output end of the second Z-axis driver 336 is connected to a connecting frame 3361 arranged along the Z-axis direction. The lower end of the connecting frame 3361 passes through the through-slots of the base plate 332 and is slidably connected to the linear guide rail 3371. When the first pressing plate 335 and the second pressing plate 337 are in contact with the large end 201 and the small end 202, the first pressing plate 335 and the second pressing plate 337 roll and shape the corresponding large end 201 and the small end 202 through the sliding of the sliding plate 334 on the linear guide rail 3321 and the sliding of the linear guide rail 3371 relative to the connecting frame 3361. The first Z-axis driver 331, the Y-axis driver 333 and the second Z-axis driver 336 can all use linear motors.

[0042] Combination Figure 7 , Figure 8 and Fig.10In a preferred embodiment of the present invention, a discharge trough 31a arranged along the X-axis direction is provided on the rolling table 31, and the rolling mechanism 33 can roll the heat dissipation tube 200 into the discharge trough 31a, so as to facilitate the receiving and transfer of the material by the unloading device 40. Preferably, at least two discharge troughs 31a are provided on the rolling table 31, and the two discharge troughs 31a are arranged in parallel and spaced apart along the Y-axis direction. The spaced apart arrangement effectively prevents the collision problem between the heat dissipation tubes 200 during the rolling process. The rolling mechanism 33 can roll at least two heat dissipation tubes 200 into at least two discharge troughs 31a one by one at the same time, and can simultaneously realize the rounding and shaping of at least two heat dissipation tubes 200, thereby effectively improving the production efficiency.

[0043] Combination Figure 7 , Figure 8 and Fig.10 In a preferred embodiment of the present invention, the rounding device 30 further includes a pushing mechanism 34 disposed on at least one side of the rounding platform 31. The pushing mechanism 34 can move linearly along the Y-axis direction relative to the rounding platform 31 to push the heat dissipation pipe 200 into the discharge trough 31a. More specifically, the pushing mechanism 34 includes a pushing driver 341 and a pushing member 342 connected to the output end of the pushing driver 341. The pushing driver 341 is mounted on the working platform 101 and is located at the lower side of the rounding platform 31. The pushing member 342 abuts against the upper surface of the rounding platform 31 and is in a strip shape. Driven by the pushing driver 341, the pushing member 342 can move linearly along the Y-axis direction, thereby moving from one side of the rounding platform 31 to the other side of the rounding platform 31. During the movement, the heat dissipation pipe 200 that has been rounded and shaped on the rounding platform 31 is pushed into the discharge trough 31a. No matter how many heat dissipation tubes 200 and corresponding discharge slots 31a are arranged on the rolling table 31, the heat dissipation tubes 200 on the rolling table 31 can be pushed one by one into the corresponding discharge slots 31a by moving a pusher 342, and the structure is simple and efficient. Of course, the number of pushers 342 can also be two, so that at least two heat dissipation tubes 200 on the rolling table 31 can be pushed from both sides, and each heat dissipation tube 200 can be pushed one by one into the corresponding discharge slot 31a efficiently.

[0044] Combination Figure 8 and Fig.10In a preferred embodiment of the present invention, the rounding device 30 further includes a cleaning mechanism 35 disposed between the rounding table 31 and the rolling mechanism 33. The cleaning mechanism 35 includes a bracket 103 disposed on the working platform 101, a cleaning driver 351 mounted on the bracket 103, and a cleaning brush 352 connected to the output end of the cleaning driver 351. The cleaning brush 352 is located near the discharge end of the rounding table 31, and has two upper and lower rows of brush heads and a blowing hole located between the two rows of brush heads. The cleaning driver 351 can drive the cleaning brush 352 to move linearly along the X-axis direction, so that the upper row of brush heads can clean the first pressing plate 335 and the second pressing plate 337, and the lower row of brush heads can clean the rounding table 31 and the discharge trough 31a, and clean while blowing air, thereby ensuring the smooth implementation of the rounding shaping and pushing and unloading actions. The cleaning driver 351 can use a rodless cylinder. In order to collect the waste materials generated in the production process such as the cleaned powder, the cleaning mechanism 35 also includes a waste collection box 353 . The waste collection box 353 is specifically arranged at a position close to the discharge end of the rolling table 31 .

[0045] Combination Figure 1 , Figure 2 , Figure 7 and Fig.10 The unloading device 40 includes a receiving mechanism 41 and a conveying rail 42 which are arranged in parallel and at intervals, and a unloading mechanism 43 which is mounted between the receiving mechanism 41 and the conveying rail 42. The receiving mechanism 41 can make a linear motion towards or away from the rounding device 30 to receive and transfer the rounded heat pipe 200. The unloading mechanism 43 can move linearly along the Z-axis, Y-axis and X-axis directions to take the heat pipe 200 transferred by the receiving mechanism 41 and place it on the conveying rail 42. The conveying rail 42 is used to transfer the heat pipe 200 for unloading.

[0046] Specifically, the material receiving mechanism 41 includes a bracket 104 mounted on the work platform 101, a material receiving driver 411 arranged on the bracket 104, and a plug-in 412 connected to the output end of the material receiving driver 411. The plug-in 412 is arranged in a one-to-one correspondence with the discharge slot 31a on the rolling table 31, and has a material receiving slot 412a for receiving the heat dissipation tube 200. The material receiving driver 411 can drive the plug-in 412 to move linearly along the X-axis direction to enter and exit the discharge slot 31a, so as to deliver the heat dissipation tube 200 from the rolling table 31 to a position convenient for the unloading mechanism 43 to pick up and deliver. Among them, the cross-sectional shape of the discharge slot 31a is "T"-shaped or "L"-shaped, the shape of the plug-in 412 matches the shape of the discharge slot 31a, the cross-sectional shape of the receiving slot 412a is "V"-shaped, and the material receiving driver 411 can adopt a linear cylinder. Both the material discharging trough 31a and the material receiving trough 412a can be made of flexible materials, so that the heat dissipation pipe 200 will not be damaged during the discharging and receiving process. In this embodiment, the bracket 104, the material receiving driver 411 and the plug-in connector 412 are arranged in a one-to-one correspondence, and the number of the three is two, so that two rounded heat dissipation pipes 200 can be received and transferred to the unloading mechanism 43 at the same time. It should be noted that the specific structure of the unloading mechanism 43 is roughly the same as that of the loading mechanism 12, and the main difference is that the actions to be completed are different, so it will not be repeated here.

[0047] See also Figure 2 The conveying guide rail 42 is arranged along the X-axis direction, and has a feeding position and a discharging position on two opposite sides thereof. The empty positioning fixture 421 flows into the machine from the feeding position close to the loading mechanism 12, is transferred to the discharging position on the conveying guide rail 42, and receives the heat dissipation tube 200 transferred by the unloading mechanism 43 at the discharging position. The positioning fixture 421 loaded with heat dissipation tube 200 continues to be transferred on the conveying guide rail 42, and then is transferred out of the machine for discharging. Among them, the discharging position, the unloading mechanism 43 and the receiving mechanism 41 at the feeding position are arranged in a straight line, so that the transfer stroke of the unloading mechanism 43 can be shortened and the efficiency can be improved.

[0048] The following combination Figures 1 to 10 , the working principle of the feeding and rounding machine 100 of the present invention is described:

[0049] After the equipment is started, the feeding mechanism 11 transfers the material tray 300 loaded with heat dissipation tubes 200 and positions it at a position convenient for the loading mechanism 12 to pick up materials. When the sensor located here senses the material tray 300, it sends a signal to the controller. Under the instruction of the controller, the loading mechanism 12 moves back and forth between the feeding mechanism 11 and the positioning device 20, and transfers two heat dissipation tubes 200 to the first two positioning seats 211 on the receiving table 21 each time; after the sensor located at the alignment mechanism 22 senses the heat dissipation tube 200, it sends a signal to the controller. Under the instruction of the controller, the alignment mechanism 22 moves. The two heat pipes 200 are adjusted to the same position at the same time. After that, the supporting mechanism 23 is operated to carry and transfer the aligned two heat pipes 200 to the two middle positioning seats 211. When the sensor located here senses the heat pipes 200, it sends a signal to the controller. Under the instruction of the controller, the rotating mechanism 24 is operated to drive the heat pipes 200 on the two middle positioning seats 211 to rotate. During the rotation process, the line scanning camera 25 identifies the straightness, roundness and flatness of the tube bodies of the two rotating heat pipes 200, and feeds back the identification information to the controller. Then, the supporting mechanism 23 is operated to carry and transfer the aligned two heat pipes 200 to the two middle positioning seats 211. When the sensor senses the heat pipes 200, it sends a signal to the controller. Under the instruction of the controller, the rotating mechanism 24 is operated to drive the heat pipes 200 on the two middle positioning seats 211 to rotate. During the rotation process, the line scanning camera 25 identifies the straightness, roundness and flatness of the tube bodies of the two rotating heat pipes 200, and feeds back the identification information to the controller. The mechanism transfers the qualified heat dissipation tubes to the rear two positioning seats 211; then, the feeding mechanism 32 is activated to transfer two heat dissipation tubes 200 to the rolling table 31 each time, and the heat dissipation tubes 200 that were previously unqualified are diverted and transferred by the feeding mechanism 32 and placed in the defective product collection box 326; when the sensor on the rolling table 31 senses the heat dissipation tube 200, it sends a signal to the controller, and under the instruction of the controller, the rolling mechanism 33 is activated to roll and shape the two heat dissipation tubes 200 at the same time each time, and then the pushing mechanism 34 pushes the rounded heat dissipation tubes 200 to the corresponding In the discharge trough 31a, at this time, the connector 412 in the discharge trough 31a at the initial position receives the heat pipe 200 and transfers the received heat pipe 200 to the unloading mechanism 43; when the sensor located at the unloading mechanism 43 senses the heat pipe 200, it sends a signal to the controller. Under the instruction of the controller, the unloading mechanism 43 takes and places the two heat pipes 200 transferred by the receiving mechanism 41 on the positioning fixture 421 of the conveying guide rail 42 at the same time each time, and the conveying guide rail 42 conveys the positioning fixture 421 full of heat pipes 200, so as to be discharged from the machine;

[0050] By repeating the above operation continuously, the automatic production line operation of rolling and rounding the heat dissipation tube 200 can be realized.

[0051] Compared with the prior art, the loading and rounding machine 100 of the present invention comprises a loading device 10 and a unloading device 40 arranged at intervals, a rounding device 30 is arranged between the loading device 10 and the unloading device 40, and a positioning device 20 is also arranged between the loading device 10 and the rounding device 30. Through the loading device 10, not only the automatic and continuous loading of the heat dissipation tube 200 can be realized, but also the heat dissipation tube 200 can be automatically transferred to the positioning device 20, and the positioning device 20 performs alignment adjustment and transfer of the heat dissipation tube 200 after the alignment adjustment, so that the rounding device 30 moves linearly relative to the heat dissipation tube 200 it undertakes, so as to synchronously round and shape the large end 201 and the small end 202 of the heat dissipation tube 200 of different diameters, and the unloading device 40 takes the rounded heat dissipation tube 200 out of the rounding device 30 and transfers it out. The whole machine has a simple structure and a reasonable layout, and can efficiently and accurately realize the automated assembly line operation of rolling the heat dissipation tube 200 with a certain length and different diameters.
