Description

Technical Field

[0001] The present invention relates to the field of radiator assembly, and particularly to an automatic sealing machine for hermetically welding the pipe orifices of heat dissipation pipes. Background Art

[0002] With the rapid development of science and technology, electronic products such as mobile phones, tablet computers, in-vehicle computers, etc. are developing towards high-density integration and ultra-fine precision. The heat dissipation performance of electronic products has become increasingly important. Therefore, the requirements for the processing precision of radiators used in electronic products are also getting higher and higher. This involves operations such as shrinking the orifice at the large end of a relatively special heat dissipation pipe with a certain length and unequal diameters, then hermetically welding the orifice after shrinking, and then injecting water into the heat dissipation pipe with the orifice at the large end sealed, and then sealing the orifice at the small end of the heat dissipation pipe after water injection. Since the heat dissipation pipe is a precision component, its pipe wall is relatively thin, and the copper pipe body is prone to deformation and difficult to position. Moreover, the amount of injected water must be strictly controlled within the required numerical range. Therefore, whether the orifice at the large end of the heat dissipation pipe before water injection is precisely welded directly affects whether the subsequent manufacturing processes can be successfully completed.

[0003] Therefore, there is an urgent need for a simple-structured, high-welding-precision and efficient automatic sealing machine to solve the above problems. Summary of the Invention

[0004] The object of the present invention is to provide an automatic sealing machine with a simple structure, high welding precision and high efficiency.

[0005] To achieve the above object, the present invention discloses an automatic sealing machine, which includes a first conveying device and a second conveying device vertically arranged on a working platform, a loading device and an unloading device arranged in sequence along the conveying direction of the first conveying device, and two welding devices and a detection device arranged in sequence along the conveying direction of the second conveying device between the loading device and the unloading device. The detection device is located at a position adjacent to the first conveying device. The first conveying device is used to convey the heat dissipation pipes before and after welding. The loading device shuttles between the first conveying device and the second conveying device and is used to sequentially transfer the heat dissipation pipes to be welded on the first conveying device to the second conveying device. The second conveying device is used to sequentially convey the received heat dissipation pipes towards the two welding devices, the detection device and the unloading device. The two welding devices can alternately perform hermetic welding on the orifices of the passing heat dissipation pipes. The detection device is used to detect and perform code scanning and identification on the welded heat dissipation pipes passing through. The unloading device shuttles between the second conveying device and the first conveying device and is used to transfer the detected heat dissipation pipes to the first conveying device for continuous conveying and discharging.

The feeding device and the discharging device are respectively arranged on the front and rear sides of the first conveying device. Two welding devices and a detection device arranged between the feeding device and the discharging device are sequentially arranged on the second conveying device. The feeding device shuttles between the first conveying device and the second conveying device, so as to sequentially transfer the heat dissipation pipes to be welded from the first conveying device to the second conveying device. During the process that the second conveying device conveys the heat dissipation pipes towards the two welding devices, the detection device and the discharging device, the welding device performs closed welding on the pipe orifices of the passing heat dissipation pipes, the detection device detects and performs code scanning and identification on the welded heat dissipation pipes after passing, and the discharging device shuttles between the second conveying device and the first conveying device, so as to transfer the detected heat dissipation pipes to the first conveying device for continuous conveying and discharging. The whole machine has a simple and compact structure, effectively utilizes space, has a reasonable layout, and can efficiently and accurately realize the automated assembly line operation of closing and welding the pipe orifices of heat dissipation pipes with a certain length and different diameters. Moreover, the two welding devices alternately perform closed welding on the pipe orifices of the passing heat dissipation pipes, which is convenient for alternately replacing the welding materials and the positive electrode blocks of the two welding devices, so as to overcome the problem of excessive consumption of welding materials, and can also overcome the problem that the positive electrode blocks are easily oxidized and blackened in the air at high temperature, generating an oxide film and affecting the welding effect, thereby realizing the continuous welding operation of the whole machine and further improving the welding efficiency.

[0027] To describe in detail the content, structural features, achieved objectives and effects of the present invention, the following will be described in detail in conjunction with the embodiments and with reference to the drawings.

[0028] Refer to Figures 1 to 3 , the present invention discloses an automatic sealing machine 100, which is suitable for welding the pipe orifice of a heat dissipation pipe 200 to seal the pipe orifice. In this application, the heat dissipation pipe 200 is specifically a part of a radiator used in electronic products such as mobile phones, tablet computers, in-vehicle computers, etc. Among them, the heat dissipation pipe 200 is a copper pipe with a certain length, the length is approximately 280 - 330 mm, the overall shape is approximately tubular, and it has a large end 201 and a small end 202 with different diameters. In this machine, neither the large end 201 with a relatively large diameter nor the small end 202 with a relatively small diameter of the heat dissipation pipe 200 is sealed. The pipe orifice of the small end 202 serves as a water injection port, with a diameter of approximately 3 - 4 mm. The pipe orifice of the large end 201 has been swaged and has a tapered necking. This machine mainly seals and welds the pipe orifice of the large end 201 to seal the tapered necking, so as to facilitate subsequent operations related to injecting water into the heat dissipation pipe 200 and sealing the water injection port.

[0029] Refer to Figures 1 to 3, the automatic sealing machine 100 provided by the preferred embodiment of the present invention includes a first conveying device 10 and a second conveying device 30 vertically arranged on a working platform 101, a feeding device 20 and a discharging device 60 arranged in sequence along the conveying direction of the first conveying device 10, two welding devices 40 and a detection device 50 arranged in sequence along the conveying direction of the second conveying device 30 between the feeding device 20 and the discharging device 60, and the detection device 50 is located at a position adjacent to the first conveying device 10. The first conveying device 10 is used to convey the heat dissipation tubes 200 before and after welding. The feeding device 20 shuttles between the first conveying device 10 and the second conveying device 30, and is used to sequentially transfer the heat dissipation tubes 200 to be welded on the first conveying device 10 to the second conveying device 30. The second conveying device 30 is used to sequentially convey the received heat dissipation tubes 200 in the direction of the two welding devices 40, the detection device 50 and the discharging device 60. The two welding devices 40 can alternately perform closed welding on the pipe orifices of the passing heat dissipation tubes 200. The detection device 50 is used to detect and perform code scanning and identification on the welded heat dissipation tubes 200 passing through. The discharging device 60 shuttles between the second conveying device 30 and the first conveying device 10, and is used to transfer the detected heat dissipation tubes 200 to the first conveying device 10 for continuous conveying to discharge. Of course, the automatic sealing machine 100 of the present invention further includes a controller, and the controller is electrically connected to the first conveying device 10, the feeding device 20, the second conveying device 30, the welding device 40, the detection device 50 and the discharging device 60, and is used to control the coordinated actions among the devices. Among them, the controller is a prior design, and its structure and control principle are well known in the art, so it will not be described in detail here.

[0030] Refer to Figure 3 and Figure 4, the first transfer device 10 includes a transfer guide rail 11, a carrier 12 that is transferred on the transfer guide rail 11, and a stacking mechanism 13 disposed beside the transfer guide rail 11. The transfer guide rail 11 is arranged on the working platform 101 along the X-axis direction. The transfer guide rail 11 is successively provided with a feeding position 11a, a loading position 11b, a welding position 11c, a discharging position 11d, and an unloading position 11e. The loading device 20 is disposed at a position corresponding to the loading position 11b, the unloading device 60 is disposed at a position corresponding to the discharging position 11d, the welding device 40 and the detection device 50 are located at positions flush with the welding position 11c. The feeding position 11a and the unloading position 11e are suspended at the edges of the front and rear ends of the working platform 101, so as to be located outside the machine and used for docking with other equipment on the production line. The carrier 12 is used to transport the heat dissipation pipes 200 before and after welding. The heat dissipation pipes 200 before and after welding are arranged at equal distances on the carrier 12. The carriers 12 can be stacked in groups of at least two and transferred on the transfer guide rail 11, so as to improve the transfer efficiency and facilitate docking with other equipment on the production line. Specifically, in this embodiment, the carriers 12 full of heat dissipation pipes 200 to be welded are transferred into the machine in pairs and stacked, and the carriers 12 full of heat dissipation pipes 200 after welding are transferred out of the machine in pairs and stacked. The number of the stacking mechanisms 13 is correspondingly 2. One of the stacking mechanisms 13 is used to layer-by-layer separate the stacked carriers 12 at the loading position 11b, so that the carriers 12 are placed in a single layer at the welding position 11c, thus facilitating the loading device 20 and the unloading device 60 to pick and place materials. The other stacking mechanism 13 is used to layer-by-layer stack the carriers 12 after welding at the discharging position 11d, so as to be transferred out of the machine in pairs and stacked at the unloading position 11e.

[0031] Specifically, the stacking mechanism 13 includes a lifting cylinder (not shown in the figure) provided at the bottom end of the transfer guide rail 11, a lifting frame 131 connected to the output end of the lifting cylinder, at least two pushing cylinders 132 symmetrically arranged on the left and right side plates of the lifting frame 131, and at least two plugging plates 133 slidably arranged on the left and right side plates of the lifting frame 131 and connected to the at least two pushing cylinders 132 in a one-to-one correspondence. Among them, the left and right side plates of the lifting frame 131 are symmetrically arranged on the left and right opposite sides of the transfer guide rail 11 in the Y-axis direction. One side of the plugging plate 133 facing the transfer guide rail 11 has a plugging portion 1331, and the plugging portion 1331 matches the plugging holes on the side wall of the carrier 12. The lifting cylinder can drive the lifting frame 131 to move linearly in the Z-axis direction, so that the left and right side plates drive the two plugging plates 133 to move closer to or away from the stacked carriers 12 accordingly. Thus, under the drive of the corresponding pushing cylinders 132, the corresponding plugging portions 1331 of the two plugging plates 133 can be inserted into or withdrawn from the plugging holes of the opposite carriers 12 from the left and right sides, so as to fix or release the fixation of the carrier 12, enabling it to be separated from the transfer of the transfer guide rail 11 or to fall back onto the transfer guide rail 11, thereby facilitating stacking or releasing stacking. It should be noted that for the convenience of description and understanding, the X-axis direction mentioned in this application refers to the direction parallel to the transfer direction of the first transfer device 10, the Y-axis direction refers to the direction perpendicular to the transfer direction of the first transfer device 10, and the Z-axis direction refers to the direction perpendicular to the plane formed by the X-axis and the Y-axis.

[0032] Specifically, the stacking mechanism 13 further includes a supporting mechanism 14 provided at the welding position 11c. The supporting mechanism 14 includes a pushing cylinder 141 provided below the transfer guide rail 11 and a pushing plate 142 connected to the output end of the pushing cylinder 141. The pushing cylinder 141 can drive the pushing plate 142 to perform a linear reciprocating motion in the Z-axis direction to jack up the single-layer carrier 12 transferred to this station to be separated from the transfer of the transfer guide rail 11 or to place the jacked-up carrier 12 back onto the transfer guide rail 11, so as to facilitate the material taking of the feeding device 20 and the material placing of the discharging device 60, and can enable the carrier 12 after the material placing to continue to be transferred on the transfer guide rail 11.

[0033] Refer to Figure 1 、 Figure 2 and Figure 5, the feeding device 20 includes a feeding mechanism 21 mounted above the first conveying device 10 and the second conveying device 30 and a clamping member 22 connected to the output end of the feeding mechanism 21. The feeding mechanism 21 can drive the clamping member 22 to perform linear reciprocating motions along the X-axis, Y-axis, and Z-axis, so as to sequentially transfer the heat dissipation tubes 200 to be welded on the first conveying device 10 to the second conveying device 30. Specifically, in this embodiment, the feeding mechanism 21 includes a bracket 211 mounted on the working platform 101 along the Y-axis direction, a Y-axis driver 212 installed on the bracket 211, an X-axis driver 213 connected to the output end of the Y-axis driver 212, a first Z-axis driver 214 connected to the output end of the X-axis driver 213, a second Z-axis driver 215 connected to the output end of the first Z-axis driver 214, and a clamping driver 216 connected to the output end of the second Z-axis driver 215. The clamping member 22 is connected to the output end of the clamping driver 216. The Y-axis driver 212 and the X-axis driver 213 correspondingly drive the clamping member 22 to perform linear reciprocating motions along the Y-axis and X-axis directions. The first Z-axis driver 214 and the second Z-axis driver 215 are used to drive the clamping member 22 to perform linear reciprocating motions along the Z-axis direction, so that the clamping member 22 shuttles between the first conveying device 10 and the second conveying device 30, thereby realizing the picking and delivering operations of the heat dissipation tubes 200 to be welded under the drive of the clamping driver 216, effectively improving the feeding efficiency. Among them, the Y-axis driver 212, the X-axis driver 213, and the first Z-axis driver 214 can all adopt linear motors. The second Z-axis driver 215 and the clamping driver 216 can select linear cylinders, and the clamping member 22 is a pneumatic gripper. The clamping member 22 has a clamping surface corresponding to the shape of the heat dissipation tube 200, and the shape of the clamping surface is "V"-shaped, so as to be compatible with the clamping operations of heat dissipation tubes 200 with different diameter sizes. A flexible buffer layer is also provided on the clamping surface of the clamping member 22 that abuts against the heat dissipation tube 200, so as to better protect the heat dissipation tube 200. Preferably, the number of the clamping members 22 is two, and the clamping members 22, the second Z-axis driver 215, and the clamping driver 216 are arranged in one-to-one correspondence, so that two heat dissipation tubes 200 can be picked and delivered each time, further improving the feeding efficiency.

[0034] Refer to Figure 6 and Figure 7, the second transfer device 30 includes a loading table 31 for receiving the heat dissipation pipe 200, an alignment mechanism 32 provided at the front end of the loading table 31, and a supporting mechanism 33 provided below the loading table 31. A plurality of loading seats 311 arranged in parallel and equidistantly along the Y-axis direction are provided on the loading table 31. The alignment mechanism 32 is located at a position flush with the loading seats 311 at the front end of the loading table 31, and can specifically move linearly along the X-axis relative to the loading table 31 to push the heat dissipation pipe 200 placed on the loading seats 311 at the front end of the loading table 31, thereby adjusting the placement position of the heat dissipation pipe 200 in the loading seats 311. The supporting mechanism 33 can move linearly along the Z-axis and the Y-axis relative to the loading table 31 to lift the heat dissipation pipe 200 on the loading seats 311 of the previous station from the loading table 31 and transfer it to the loading seats 311 of the next station, so as to realize the synchronous transfer of the aligned heat dissipation pipe 200, the welded heat dissipation pipe 200, and the inspected heat dissipation pipe 200. Specifically, the cross-sectional shape of the loading seat 311 is generally "concave", and a "V"-shaped placement groove 311a is provided at its top end, so as to be compatible with the placement of heat dissipation pipes 200 with different diameters. An inductor 312 is also provided at each loading seat 311 for sensing whether the heat dissipation pipe 200 is supported and placed on the loading seat 311 of the corresponding station. The inductor 312 is preferably a transmissive inductor.

[0035] Specifically, the alignment mechanism 32 includes alignment seats 321 and push plates 322 which are arranged on two opposite sides of the front end of the receiving table 31 at intervals in the X-axis direction. The alignment seats 321 are made of POM material. The alignment seats 321 are provided with positioning grooves 321a. The cross-sectional shape of the positioning grooves 321a is in a "V" shape, a "Y" shape or a "U" shape, which can adapt to the placement of the small ends 202 of heat dissipation tubes 200 with different diameter sizes, effectively improving the versatility of the alignment seats 321. The push plates 322 can move linearly in the X-axis direction under the drive of the associated push drives 323, so as to push against the heat dissipation tubes 200 on the receiving seats 311, so as to adjust the length of the small ends 202 of the heat dissipation tubes 200 extending out of the positioning grooves 321a of the alignment seats 321, that is, to adjust the length of the pipe orifices of the large ends 202 of the heat dissipation tubes 200 to be welded extending out of the receiving seats 311, thereby realizing the adjustment of the placement positions of the heat dissipation tubes 200 on the receiving seats 311, facilitating subsequent high-efficiency and accurate alignment welding operations. Among them, the alignment seats 321 can move linearly in the Z-axis direction and the X-axis direction correspondingly under the drive of the associated lifting drives 324 and push drives 325 to adapt to the alignment placement of the small ends 202 of heat dissipation tubes 200 with different diameter sizes and different length sizes. Specifically, in this embodiment, the number of the alignment mechanisms 32 is two, and they can be mounted on the working platform 101 through mounting frames 326 arranged on the lower side of the receiving table 31. The two alignment mechanisms 32 are arranged in one-to-one correspondence with the two receiving seats 311 arranged in sequence at the front end of the receiving table 31, so as to adjust the positions of the heat dissipation tubes 200 on the corresponding receiving seats 311, thereby realizing uninterrupted alignment operations and effectively improving the alignment efficiency.

[0036] Specifically, the supporting mechanism 33 includes two brackets 331 which are symmetrically arranged on two opposite sides of the receiving platform 31 along the X-axis direction. The two brackets 331 are respectively connected to the output ends of the lifting driver 332 located on the lower side of the receiving platform 31. The lifting driver 332 is connected to the output end of the transfer driver 333. The two brackets 331 can move linearly along the Z-axis direction under the drive of the lifting driver 332, so that they can move up to support the aligned heat dissipation pipe 200 to be separated from the receiving seat 311. The two brackets 331 can also move linearly along the Y-axis direction under the drive of the transfer driver 333 to transfer the supported heat dissipation pipe 200 to the receiving seat 311 corresponding to the welding device 40, the detection device 50 and the unloading device 60, so as to facilitate the welding device 40, the detection device 50 and the unloading device 60 to complete the corresponding welding, detection and identification and unloading operations. The two brackets 331 are correspondingly connected to the left and right side walls of the receiving platform 31, and the brackets 331 are correspondingly provided with brackets 331a connected to the placement grooves 311a of the receiving seat 311. The cross-sectional shape of the brackets 331a is "V" shaped, so as to adapt to the support of heat pipes 200 of different diameters. The number of brackets 331a on each side of the bracket 331 is at least one less than the number of the receiving seat 311, so that the heat pipes 200 on the receiving seat 311 of the previous station are gradually transferred to the receiving seat 311 of the next station without interruption, effectively improving the transfer efficiency.

[0037] Specifically, in this embodiment, the transfer driver 333 is installed on the working platform 101. A connecting seat 334 is connected to the output end of the transfer driver 333. The lifting driver 332 is installed on the connecting seat 334. A sliding seat 335 is slidably arranged on the connecting seat 334, and the sliding seat 335 is connected to the output end of the lifting driver 332. Two connecting plates 336 corresponding to the two brackets 331 are arranged on the sliding seat 335. The lifting driver 332 can drive the sliding seat 335 to linearly move along the Z-axis direction, so that the two connecting plates 336 move upward synchronously to push the brackets 331 away from the receiving table 331. Then, the transfer driver 333 drives the connecting seat 334 to linearly move along the Y-axis direction, so as to transfer the heat dissipation tubes 200 carried on the two brackets 331 to the receiving seat 311 at the next station. Wherein, in order to achieve the stability of the two brackets 331 for lifting and transferring, the lifting driver 332 and the transfer driver 333 can be arranged at the relative center of the receiving table 31. At this time, the number of the lifting driver 332 and the transfer driver 333 corresponds to one, and the structure is simple and the transfer is convenient. Of course, the two can also be correspondingly arranged at the relative rear side of the receiving table 31. In this case, at least one lifting driver 337 and two connecting plates 338 correspondingly connected to the output end of the lifting driver 337 are further arranged below the relative front side of the receiving table 31. The two connecting plates 338 are correspondingly connected to the two brackets 331. At least one lifting driver 337 is slidably arranged on the mounting frame 326 through a linear guide rail 339 arranged on the mounting frame 326. The lifting driver 337 can drive the connected connecting plate 338 to linearly move along the Z-axis direction, so as to push the bracket 331 at the relative front side of the receiving table 31. When the transfer driver 333 drives the bracket 331 to move back and forth, the connecting plate 338 synchronously slides on the linear guide rail 339, so as to realize the stable movement of the bracket 331. Of course, in other embodiments, the number of the lifting driver 332 and the transfer driver 333 can also correspond to two, and the two lifting drivers 332 and the two transfer drivers 333 are correspondingly arranged on the front and rear opposite sides of the receiving table 31 along the Y-axis direction.

[0038] Refer to Figure 6 、 Figure 8 and Figure 9, the welding device 40 includes a substrate 41 installed on the working platform 101, a positioning stage 42 and a welding head 43 arranged at intervals along the X-axis direction on the substrate 41. The positioning stage 42 can move linearly along the Z-axis direction to fix the heat dissipation tube 200 from the relatively outer side of the second conveying device 30. The welding head 43 can move linearly along the X-axis, Y-axis and Z-axis directions to approach or move away from the pipe orifice at the large end of the heat dissipation tube 200 positioned on the positioning stage 42, so as to perform sealed welding on the pipe orifice. Among them, the welding head 43 includes a bracket 431 installed on the substrate 41, a Y-axis driver 432 arranged on the bracket 431, an X-axis driver 433 connected to the output end of the Y-axis driver 432, a Z-axis driver 434 connected to the output end of the X-axis driver 433, a welding torch 435 connected to the output end of the Z-axis driver 434, and a welding material 436 clamped at the terminal of the welding torch 435. The welding material 436 is located at a position opposite to the pipe orifice of the large end 201 of the heat dissipation tube 200 on the positioning stage 42. The Y-axis driver 432, the X-axis driver 433 and the Z-axis driver 434 are used to drive the welding torch 435 to drive the welding material 436 to move linearly along the Y-axis, X-axis and Z-axis directions to approach or move away from the heat dissipation tube 200, so as to realize the corresponding welding actions. The Y-axis driver 432, the X-axis driver 433 and the Z-axis driver 434 can all adopt linear motors. Among them, the present application uses argon arc welding, and the positive electrode block of the welding device 40 is detachably installed at the side end of the positioning stage 42.

[0039] Specifically, the positioning stage 42 includes a positioning seat 421 and a receiving stage 422 disposed opposite to each other on the substrate 41 along the X-axis direction. There are two receiving seats 4221 arranged at intervals along the X-axis direction on the receiving stage 422. The receiving seat 4221 includes a receiving groove 422a provided at its top side end and two receiving wheels 4222 rotatably embedded in the receiving groove 422a. The two receiving wheels 4222 are symmetrically arranged in the receiving groove 422a. The heat dissipation pipe 200 is carried in the receiving grooves 422a of the two receiving seats 4221 and abuts against the corresponding two receiving wheels 4222 in the two receiving grooves 422a, so as to be rotatably placed on the receiving stage 422. The arrangement of the two receiving seats 4221 and the corresponding two receiving wheels 4222 can not only accommodate the loading of heat dissipation pipes 200 with different lengths and different diameters, but also provide a relatively gentle loading force through the two rotatable receiving wheels 4222, thereby better protecting the heat dissipation pipe 200. Preferably, the receiving wheel 4222 is a PU wheel, so as to better protect the heat dissipation pipe 200. The positioning seat 421 can move linearly along the X-axis direction to approach or move away from the receiving stage 422, so that the small end 202 of the heat dissipation pipe 200 on the receiving stage 422 can be rotatably inserted into the positioning groove 421a of the positioning seat 421 to fix the small end 202 of the heat dissipation pipe 200 with a certain length suspended outside the receiving stage 422. Among them, both the positioning seat 421 and the receiving seat 4221 can be made of POM material, so as to better protect the heat dissipation pipe 200. The cross-sectional shape of the receiving groove 422a is in the shape of "V" or "Y", and the cross-sectional shape of the positioning groove 421a is in the shape of "U", so as to adapt to the placement of heat dissipation pipes 200 with different diameter sizes, effectively improving the versatility of the positioning stage 42. More specifically, the positioning seat 421 is connected to the output end of the pushing driver 4211, so as to move linearly along the X-axis direction to approach or move away from the heat dissipation pipe 200 on the receiving stage 422 under the drive of the pushing driver 4211. Further, the pushing driver 4211 is connected to the output end of the adjustment driver 4212 provided on the substrate 41, so as to move linearly along the X-axis direction under the drive of the adjustment driver 4212, thereby driving the relative movement of the positioning seat 421 to adapt to the alignment placement of the small end 202 of the heat dissipation pipe 200 with different length sizes.

[0040] In a preferred embodiment of the present invention, the welding device 40 further includes a limiting mechanism 44 disposed on the upper side end of the positioning stage 42. The limiting mechanism 44 can linearly move along the Z-axis direction to abut against the heat dissipation pipe 200 on the positioning stage 42 from above, so as to prevent the heat dissipation pipe 200 from moving along the Z-axis direction, thereby further improving the welding precision.

Specifically, the limiting mechanism 44 includes a first pressing mechanism 441 and a second pressing mechanism 442 arranged on two opposite sides of the second conveying device 30 along the X-axis direction, a first pressing wheel 443 connected to the output end of the first pressing mechanism 441, and a second pressing wheel 444 connected to the output end of the second pressing mechanism 442. The first pressing wheel 443 and the second pressing wheel 444 are suspended above the receiving stage 422, and are respectively arranged in one-to-one correspondence with two receiving seats 4221 on the receiving stage 422, and are located at the central positions of two receiving wheels 4222 of the corresponding receiving seats 4221.

The first pressing wheel 443 and the second pressing wheel 444 can be made of POM material or are circumferentially provided with a flexible layer, so as to better protect the heat dissipation pipe 200.

[0041] More specifically, in this embodiment, the first pressing mechanism 441 includes a bracket 4411 installed on the working platform 101 and a lifting driver 4412 installed on the bracket 4411. The first pressing wheel 443 is rotatably installed at the output end of the lifting driver 4412, so as to linearly move along the Z-axis direction under the drive of the lifting driver 4412 to abut against the small end 202 of the heat dissipation pipe 200 on the receiving stage 422 from above. Among them, a spring 4413 is also connected between the first pressing wheel 443 and the output end of the lifting driver 4412, so as to achieve flexible abutment and better protect the heat dissipation pipe 200. The lifting driver 4412 can be a linear cylinder. The two first pressing mechanisms 441 corresponding to the two spaced-apart welding devices 40 can be installed on the "T"-shaped bracket 4411 at intervals, so as to optimize the structure.

The second crimping wheel 444 is rotatably mounted on the output end of the lifting drive 4422 and is connected to the driving wheel 4424 via a synchronous belt 4425. The second pressing wheel 444 can move linearly along the Z-axis direction under the drive of the lifting driver 4422 to abut against the large end 201 of the heat dissipation pipe 200 on the receiving platform 422 from above. The rotating driver 4423 can drive the driving wheel 4424 to rotate, so that the second pressing wheel 444 abutting against the heat dissipation pipe 200 rotates accordingly, thereby driving the large end 201 of the heat dissipation pipe 200 to rotate on the receiving platform 422, and the small end 202 of the heat dissipation pipe 200 rotates synchronously therewith. Among them, the lifting driver 4422 and the rotating driver 4423 respectively use linear cylinders and rotating motors.

[0043] In a preferred embodiment of the present invention, the welding device 40 further includes a drawing mechanism 45 installed on the working platform 101, and the substrate 41 is connected to the output end of the drawing mechanism 45. The drawing mechanism 45 can drive the substrate 41 to move linearly along the X-axis direction to approach or move away from the second conveying device 30, so as to facilitate the replacement of the welding material 436 and achieve uninterrupted welding. Correspondingly, the positioning platform 42 can also move linearly along the Z-axis direction under the drive of the yielding mechanism 46, so as to approach or move away from the material receiving platform 31, so that the two receiving seats 4221 on the receiving platform 422 and the positioning seat 421 can move up to a position flush with the material receiving seat 311 on the material receiving platform 31, so that the two receiving seats 4221 on the receiving platform 422 and the positioning seat 421 can move down to a position lower than the bottom surface of the material receiving platform 31, so that during the drawing process, the positioning platform 42 can move at the bottom of the material receiving platform 31, so as to slide out of the machine, and achieve the replacement of the welding material 436. In addition, the linear movement of the positioning platform 42 along the Z-axis direction can also adjust the relative height between the pipe mouth of the heat dissipation pipe 200 on the receiving platform 422 and the welding head 43, so as to adapt to the welding of heat dissipation pipes 200 of different diameters and effectively improve the welding efficiency and welding accuracy.

[0044] Specifically, the yielding mechanism 46 includes a yielding driver 461 mounted on the substrate 41, a driving block 462 connected to the output end of the yielding driver 461, and a roller 463 slidably abutting against the wedge-shaped surface of the driving block 462. The bottom end of the positioning platform 42 is slidably mounted on the substrate 41 along the Z-axis direction through a connecting assembly 464, and the bottom end of the positioning platform 42 is also connected to the roller 463 located at the center of the connecting assembly 464. The yielding driver 461 can drive the driving block 462 to move linearly along the X-axis direction, thereby driving the roller 463 to drive the positioning platform 42 to move linearly along the Z-axis direction to approach or move away from the receiving platform 31, so that the two receiving seats 4221 on the receiving platform 422 can position the heat dissipation pipe 200 beyond the receiving seat 311 from the left and right side ends of the receiving seat 311 on the receiving platform 31. The yielding driver 461 can use a linear cylinder.

[0045] See also Figure 10 and Figure 11 The detection device 50 includes a detection table 51 installed on the working platform 101, a positioning and rotating mechanism 52 arranged at the outer end of the detection table 51, a barcode scanner 53 arranged at the upper side end of the detection table 51, and an industrial camera 54 arranged at the lower side end of the detection table 51. The detection table 51 is used to receive the heat dissipation pipe 200 after welding, so that the sealing end of the large end 201 of the heat dissipation pipe 200 is located at a suspended position relative to the industrial camera 54. The positioning and rotating mechanism 52 can make linear motion along the X-axis direction and the Z-axis direction to fix the small end 202 of the heat dissipation pipe 200 that exceeds the detection table 51 from the bottom, and can also abut against the heat dissipation pipe 200 from the top, and can drive the abutted heat dissipation pipe 200 to rotate. The industrial camera 54 recognizes the shape of the sealing end of the rotating heat dissipation pipe 200, and the barcode scanner 53 recognizes the barcode on the tube body of the rotating heat dissipation pipe 200. In order to facilitate the assembly of the whole machine, the detection device 50 also includes a carrier frame 55 , and the detection platform 51 , the positioning and rotating mechanism 52 , the barcode scanner 53 and the industrial camera 54 are correspondingly installed on the carrier frame 55 .

[0046] Specifically, there are two detection seats 511 arranged at intervals along the X-axis direction on the detection table 51. A receiving groove 511a for receiving the heat dissipation pipe 200 is formed at the top side end of each detection seat 511. The structures of the two detection seats 511 may be different, but at least two receiving wheels 512 are rotatably embedded in the receiving groove 511a of at least one detection seat 511. The two receiving wheels 512 are symmetrically arranged in the receiving groove 511a along the Y-axis direction. When the heat dissipation pipe 200 is supported in the receiving grooves 511a of the two detection seats 511, it abuts against the two corresponding receiving wheels 512 in at least one receiving groove 511a, so as to be rotatably placed on the detection table 51. The length dimension and width dimension of the detection table 51 are greater than the length dimension and width dimension of the receiving seat 311 on the material receiving table 511, and the two detection seats 511 are arranged flush with the receiving seat 311, so as to support the heat dissipation pipe 200 on the receiving seat 311 from the outside of the receiving seat 311. The arrangement of the two detection seats 511 can not only be compatible with the support of heat dissipation pipes 200 of different lengths, but also provide a relatively gentle supporting force through the two rotatable receiving wheels 512 in at least one receiving groove 511a, so as to better protect the heat dissipation pipe 200. Preferably, the detection seat 511 is made of POM material, and the receiving wheel 512 is a PU wheel, so as to better protect the heat dissipation pipe 200. The cross-sectional shape of the receiving groove 511a is in a "V" shape or a "Y" shape, so as to adapt to the placement of heat dissipation pipes 200 with different diameter sizes, effectively improving the versatility of the detection table 51.

[0047] Specifically, a carrier 55 is further provided on the working platform 101. A support 551 is provided on the carrier 55. The positioning and rotating mechanism 52 includes a first pushing driver 521 and a second pushing driver 522 that are spaced apart and arranged on the carrier 55 and on two opposite sides of the detection table 51, a positioning seat 523 connected to the output end of the first pushing driver 521, a push plate 524 connected to the output end of the second pushing driver 522, a lifting driver 525 provided on the support 551, a carrier plate 526 connected to the output end of the lifting driver 525, a rotating driver 527 installed on the carrier plate 526, a driving wheel 528 rotatably installed on the carrier plate 526 and connected to the output end of the rotating driver 527, and a third pressing wheel 529 rotatably installed on the carrier plate 526 and connected to the driving wheel 528 through a synchronous belt 5281. The third pressing wheel 529 is located above the detection seat 511 having the receiving wheels 512 and is aligned with the center position between the two receiving wheels 512. The first pushing driver 521 can drive the positioning seat 523 to move linearly along the X-axis to approach or move away from the detection table 51, so that the small end 202 of the heat dissipation pipe 200 on the detection table 51 can be rotatably inserted into the positioning groove of the positioning seat 523 to fix the small end 202 of the heat dissipation pipe 200 with a certain length suspended outside the detection table 51. The second pushing driver 522 can drive the push plate 524 to move linearly along the X-axis to approach or move away from the detection table 51, so as to push the heat dissipation pipe 200 from the sealed end of the large end 201 of the heat dissipation pipe 200 on the detection table 51, so as to adjust the placement position of the heat dissipation pipe 200 in the positioning seat 523, so that the sealed end of the heat dissipation pipe 200 is located at the detection position facing the industrial camera 54. The lifting driver 525 can drive the third pressing wheel 529 to move linearly along the Z-axis to abut against the small end 202 of the heat dissipation pipe 200 from above. Then the rotating driver 527 drives the driving wheel 528 to rotate, and then drives the third pressing wheel 529 to rotate, so that the heat dissipation pipe 200 in contact with the third pressing wheel 529 rotates accordingly. Among them, the positioning seat 523 is made of POM material to better protect the heat dissipation pipe 200. The cross-sectional shape of the positioning groove of the positioning seat 523 is in a "U" shape, so as to adapt to the placement of heat dissipation pipes 200 with different diameter sizes, effectively improving the versatility of the positioning and rotating mechanism 52. Further, the first pushing driver 521 is also connected to the output end of an adjusting driver 530 provided on the carrier 55, so as to move linearly along the X-axis under the drive of the adjusting driver 530, thereby driving the positioning seat 523 to move relatively to adapt to the positioning placement of the small ends 202 of heat dissipation pipes 200 with different length sizes.

[0048] Refer to Figure 1 and Figure 2The unloading device 60 can transfer the defective products at the detection device 50 to the defective product collection area, and transfer the qualified products to the carrier 12 for further transmission for unloading. It should be noted that the specific structure of the unloading device 60 is roughly the same as that of the loading device 20. The main difference lies in the different actions to be completed and the different number of clamps used for picking up and delivering. Therefore, the specific structure of the unloading device 60 will not be described here.

[0049] The following combination Figures 1 to 11 , the working principle of the automatic sealing machine 100 of the present invention is described:

[0050] After the equipment is started, when the sensor at the feeding position 11a of the conveying guide rail 11 senses the incoming material, it sends a signal to the controller. Under the instruction of the controller, the two stacked carriers 12 loaded with heat pipes 200 are transferred from the feeding position 11a and positioned at the loading position 11b. The stacking mechanism 13 located at this station fixes the upper carrier 12 to separate it from the lower carrier 12. When the lower carrier 12 continues to be transferred to the welding position 11c on the conveying guide rail 11, the stacking mechanism 13 puts the upper carrier 12 back on the conveying guide rail 11 and waits for transfer.

[0051] When the sensor at the welding position 11c senses the carrier 12, it sends a signal to the controller. Under the instruction of the controller, the loading device 20 is activated, and moves back and forth between the conveying guide rail 11 and the second conveying device 30, and the heat dissipation tube 200 is correspondingly transferred to the receiving seat 311 on the receiving platform 31 corresponding to the alignment mechanism 32, and the alignment mechanism 32 adjusts the position of the heat dissipation tube 200 on the docking seat 311; then, under the instruction of the controller, the welding device 40 fixes the heat dissipation tube 200 after the alignment adjustment conveyed by the second conveying device 30, and drives it to rotate, so as to The heat dissipation tube 200 after welding is carried by the second conveying device 30 to the detection device 50, and the detection device 50 first positions the heat dissipation tube 200, and then drives the positioned heat dissipation tube 200 to rotate, so as to complete the corresponding detection and code scanning recognition actions during the rotation process, and feed back the detection results to the controller; under the instruction of the controller, the unloading device 60 conducts diversion and transmission of the heat dissipation tube 200 after inspection conveyed by the second conveying device 30, and the unqualified products are transferred to the unqualified product placement area, and the qualified products are transferred to the lower carrier 12 at the welding position 11c;

[0052] After the heat dissipation pipe 200 to be welded on the lower carrier 12 at the welding position 11c is taken out and the qualified products are correspondingly placed back on the lower carrier 12, the lower carrier 12 is conveyed in the direction of the blanking position 11d, and the upper carrier 12 waiting at the loading position 11b is conveyed to the welding position 11c accordingly. Then, the corresponding material taking, welding, inspection, identification and discharging operations are repeated. The stacking mechanism 13 at the blanking position 11d first lifts the conveyed lower carrier 12. When the upper carrier 12 at the welding position 11c is also conveyed to the blanking position 11d, the stacking mechanism 13 places the lifted lower carrier 12 on the upper carrier 12, and then conveys the two stacked carriers 12 in the direction of the discharging position 11e to convey them out of this machine;

[0053] By continuously repeating the above operations, the automated flow operation of welding the pipe orifice of the heat dissipation pipe 200 can be realized.

[0054] Compared with the prior art, in the automatic sealing machine 100 of the present invention, the first conveying device 10 and the second conveying device 30 are arranged perpendicular to each other. The loading device 20 and the unloading device 60 are respectively arranged on the front and rear sides of the first conveying device 10. The two welding devices 40 and a detection device 50 arranged between the loading device 20 and the unloading device 60 are sequentially arranged on the second conveying device 30. By enabling the loading device 20 to travel back and forth between the first conveying device 10 and the second conveying device 30, the heat dissipation pipe 200 to be welded can be sequentially transferred from the first conveying device 10 to the second conveying device 30. During the process of the second conveying device 30 conveying the received heat dissipation pipe 200 in the direction of the two welding devices 40, the detection device 50 and the unloading device 60, the welding device 40 performs closed welding on the pipe orifice of the heat dissipation pipe 200 to be welded passing through, and the detection device 50 performs detection and code scanning identification on the welded heat dissipation pipe 200 passing through. After detection, the unloading device 60 travels back and forth between the second conveying device 30 and the first conveying device 10, so as to transfer the detected heat dissipation pipe 200 to the first conveying device 10 for continuous conveying to discharge. The whole machine has a simple and compact structure, effectively utilizes space, has a reasonable layout, and can efficiently and accurately realize the automated flow operation of closed welding of the pipe orifices of heat dissipation pipes 200 with a certain length and unequal diameters. Moreover, the two welding devices 40 can alternately perform closed welding on the pipe orifices of the heat dissipation pipes 200 passing through, which is convenient for alternately replacing the welding materials 436 and the positive electrode blocks of the two welding devices 40, so as to overcome the problem of excessive consumption of the welding materials 436, and can also overcome the problem that the positive electrode blocks are easily oxidized and blackened in the air at high temperatures, generating an oxide film and affecting the welding effect, effectively realizing the continuous welding operation of the whole machine and further improving the welding efficiency.

[0055] The above-disclosed are only the preferred embodiments of the present invention. Certainly, the scope of rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
