Technical Field

[0001] The invention relates to the technical field of heat dissipation pipe processing and positioning, in particular to a computer heat dissipation pipe processing and positioning device. Background Art

[0002] Computer heat pipes are the core components of computer cooling systems, and their performance directly affects the heat dissipation efficiency and service life of the computer. With the continuous improvement of computer hardware performance, the demand for heat dissipation is increasing, and the production process of heat pipes is also facing higher technical requirements. At present, the production of heat pipes mainly includes processes such as heat pipe molding, capillary structure insertion, and sealing. Among them, the accurate positioning of the capillary structure is the key link to ensure the performance of the heat pipe.

[0003] The capillary structure is a structure on the inner wall of the heat pipe. When the heat pipe is sealed, the internal capillary structure cannot be seen. However, when the heat pipe is installed in the assembly, the installation position of the heat pipe needs to be determined according to the position of the capillary structure. In the prior art, the position of the capillary structure of the heat pipe is determined one by one by manual confirmation and manually marked. However, this is time-consuming and labor-intensive, resulting in inconvenient positioning and processing of the heat pipe. Summary of the invention

[0006] By adopting the above technical solution, the heat pipe is placed in the fixed groove and the positioning rod is inserted into the heat pipe. The heat pipe is driven to rotate by the rotating assembly until the positioning rod abuts against the capillary structure. At this time, the heat pipe no longer rotates, and the pressing cylinder is started to drive the pressing block to move down and insert into the fixed groove. The abutment block clamps the heat pipe for pressing and marking. There is no need for staff to manually determine the position of the capillary structure and mark it one by one, which improves the convenience of heat pipe positioning processing.

[0007] Preferably, the rotating assembly includes a first rotating roller, a second rotating roller, a rotating motor, a second rotating gear, and a pair of first rotating gears. The rotating motor is arranged on the fixed block. The first rotating roller and the second rotating roller are both rotatably arranged in the fixed groove.

The rotating shaft of the rotating motor is inserted into the gear cavity and connected to one of the first rotating gears.

[0008] By adopting the above technical solution, the heat pipe is placed between the first rotating roller and the second rotating roller. When the heat pipe needs to be rotated, the rotating motor is started. Driven by the meshing of the second driving gear, the first driving gear drives the first rotating roller and the second rotating roller to rotate synchronously in the same direction, so as to drive the heat pipe to rotate through contact friction. The operation is simple and convenient, which is convenient to use and improves the convenience of positioning and processing the heat pipe.

[0009] Preferably, the machine base is provided with a moving groove, a moving block is slidably arranged in the moving groove, the moving block is provided with a pushing groove, and a transmission assembly is arranged between the moving block and the rotating motor. The transmission assembly is used to drive the moving block to move according to the rotation of the rotating motor.

[0010] By adopting the above technical solution, when the heat pipe is placed in the fixed groove, the other end of the heat pipe is placed in the pushing groove of the moving block, which improves the stability when the heat pipe is pressed and marked. When the rotating motor is started to drive the heat pipe to rotate, the transmission assembly drives the moving block to move, so as to push the heat pipe to move and make the positioning rod insert into the heat pipe. There is no need to manually sleeve the heat pipe on the positioning rod, which improves the convenience of positioning and processing the heat pipe.

[0011] Preferably, the inner wall of the fixed groove is provided with a positioning groove, the positioning rod is slidably inserted into the positioning groove, and a positioning spring connecting the inner wall of the positioning groove and the positioning rod is arranged in the positioning groove.

[0012] By adopting the above technical solution, when the heat pipe moves while rotating following the moving block, it may occur that the capillary structure of the heat pipe gets stuck in the positioning rod. By setting the positioning groove and the positioning spring, when the capillary structure blocks the positioning rod, the positioning rod is pushed back into the positioning groove and the positioning spring is compressed. After the heat pipe rotates, the capillary structure no longer gets stuck in the positioning rod. At this time, the positioning spring restores and pushes the positioning rod to insert into the heat pipe, which improves the convenience of use.

The first transmission gear and the second transmission gear are rotatably arranged in the gear cavity and mesh with each other. The first transmission gear is connected to the rotating shaft of the rotating motor, and the second transmission gear is connected to the transmission lead screw.

[0014] By adopting the above technical solution, the rotating motor drives the first transmission gear to rotate and meshes with and drives the second transmission gear to rotate, thereby driving the transmission lead screw to rotate to drive the moving block to move in the moving groove. The operation is simple and convenient, the operation steps are simplified, it is convenient to use, the convenience of use is improved, and at the same time, the cost of the driving part is saved, realizing energy conservation and consumption reduction.

[0015] Preferably, the machine base is provided with a feeding base. A feeding block is slidably arranged on the feeding base. The bottom wall of the feeding block can abut against the top wall of the fixed block and the top wall of the moving block. The surface of the feeding block is provided with a main feeding groove. The bottom wall of the feeding block is provided with a plurality of auxiliary feeding grooves communicating with the main feeding groove. The feeding block is provided with a first closed groove and a second closed groove communicating with the auxiliary feeding groove. A first closing plate is slidably arranged in the first closed groove, and a second closing plate is slidably arranged in the second closed groove. The machine base is provided with a driving assembly for driving the first closing plate and the second closing plate to move. The first closing plate is arranged below the second closing plate.

[0016] By adopting the above technical solution, all the heat pipes to be positioned and processed are placed in the main feeding groove of the feeding block. At the same time, a heat pipe enters the auxiliary feeding groove and is blocked by the first closing plate. During processing, the feeding block is slid so that the heat pipe moves above the first rotating roller and the second rotating roller. Then, the driving assembly drives the first closing plate and the second closing plate to move. The second closing plate moves to block other heat pipes from entering the auxiliary feeding groove. The first closing plate moves and no longer blocks the heat pipe, so that the heat pipe falls into the fixed groove and lands on the first moving roller and the second moving roller. Then, the rotating motor is started to drive the heat pipe to rotate, and at the same time, the moving block is driven to move through the transmission assembly to drive the heat pipe to move so that the positioning rod is inserted into the heat pipe. The feeding steps are simplified, the operation is simple and convenient, and the convenience of use is improved.

[0017] Preferably, the feeding base is provided with a sliding groove, and the feeding block is provided with a sliding block. The sliding block is inserted into the sliding groove and can slide in the sliding groove. A sliding spring is further arranged in the sliding groove. The sliding spring connects the inner wall of the sliding groove and the sliding block.

[0018] By adopting the above technical solution, when the feeding block is slid, the sliding block slides in the sliding groove and compresses the sliding spring. After the feeding is completed, the feeding block is released, and the sliding spring restores to push the sliding block to slide, completing the automatic reset, simplifying the operation and improving the convenience of feeding.

[0019] Preferably, the driving assembly includes a first driving gear, a first driving rack, a second driving rack, a second driving gear and a third driving rack. The feeding block is provided with a driving cavity communicating with both the first closed groove and the second closed groove. The first driving gear and the second driving gear are both rotatably arranged in the driving cavity and mesh with each other.

[0020] By adopting the above technical solution, after the feeding block moves above the fixed block, manually push the third driving rack to slide and drive the second driving gear to rotate, while compressing the return spring. Through meshing, drive the first transmission gear to drive, so as to drive the first transmission rack and the second transmission rack to move. The sliding of the first transmission rack drives the first closing plate to disengage from the auxiliary feeding groove, and the sliding of the second transmission rack drives the second closing plate to insert into the auxiliary feeding groove. After the feeding is completed, release the third driving rack, and the return spring pushes the third driving rack to reset, so as to complete the reset of the first closing plate and the second closing plate, and the operation is simple and convenient.

[0021] Preferably, the driving assembly further includes a first driving rod and a second driving rod. The second driving rod is arranged on the machine base and between the fixed block and the moving block. The bottom wall of the feeding block is provided with a driving groove communicating with the driving cavity. The first driving rod is slidably arranged in the driving groove. The first driving rod is connected to the third driving rack, and the first driving rod can abut against the second driving rod.

[0022] By adopting the above technical solution, during the process of feeding by moving the feeding block, the first driving rod abuts against the second driving rod, and the second driving rod pushes the first driving rod to move, so as to drive the third driving rack to move, further simplifying the operation, improving the automation degree of feeding and facilitating feeding.

[0023] Preferably, the machine base is provided with a controller, and the controller is in signal connection with the rotating motor and the pressing cylinder. The second driving rod is provided with a distance sensor in signal connection with the controller. The distance sensor is used to detect the distance between the second driving rod and the moving block, and the controller is used to turn off the rotating motor and start the pressing cylinder according to the detection data of the distance sensor.

[0024] By adopting the above technical solution, when the rotating motor is started, it drives the moving block to move and at the same time drives the heat pipe to rotate. The moving block moves closer to the distance sensor. When the moving block moves and cooperates with the rotation of the heat pipe so that the positioning rod is inserted into the heat pipe, and after the heat pipe is located below the pressing block, the detection value of the distance sensor is less than the set value. At this time, the controller turns off the rotating motor to stop the movement of the moving block and the rotation of the heat pipe. At the same time, the controller starts the pressing cylinder to drive the pressing block to move down for pressing and marking, which simplifies the operation and improves the convenience of heat pipe positioning and processing.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the machine base, fixed block, fixed slot, pressing frame, pressing cylinder, pressing block, rotating assembly, positioning rod and abutting block, the heat pipe is placed in the fixed slot of the fixed block of the machine base and the positioning rod is inserted into the heat pipe. The rotating assembly drives the heat pipe to rotate until the positioning rod abuts against the capillary structure, thereby completing the positioning of the heat pipe. At this time, the pressing cylinder on the pressing frame is started, and the pressing block cooperates with the abutting block to press and mark on the heat pipe, completing the positioning and processing of the heat pipe. The operation is simple and convenient, and the convenience of positioning and processing is improved; 2.

The operation is simple and convenient; 3. By setting the moving slot, moving block, pushing slot, positioning slot, positioning spring and transmission assembly, when the heat pipe is placed in the fixed slot, the other end of the heat pipe is inserted into the pushing slot of the moving block. When the rotating motor rotates, it drives the moving block to move in the moving slot through the transmission assembly. The inner wall of the pushing slot abuts against and pushes the heat pipe to move, so that the positioning rod is inserted into the heat pipe. At the same time, during this process, if the capillary structure abuts against the positioning rod, it will push the positioning rod to be inserted into the positioning slot and compress the positioning spring. Cooperating with the rotation of the heat pipe, when the positioning rod does not abut against the capillary structure, the positioning spring restores to push the positioning rod to be inserted into the heat pipe, realizing automatic feeding and improving the convenience of operation.

By inserting the positioning rod 221 into the heat pipe and driving the heat pipe to rotate by means of the rotating assembly 4, the positioning rod 221 abuts against the capillary structure to position the heat pipe. At this time, pressing is performed through the pressing cylinder 241, and marks can be made at corresponding positions, thereby completing the positioning processing of the heat pipe, which is convenient and fast. The position of the capillary structure can be quickly corresponded through the marks on the processed heat pipe.

[0035] In order to improve the convenience of use, referring to Figure 3 and Figure 4 , the rotating assembly 4 includes a plurality of first rotating rollers 44, a plurality of second rotating rollers 45, a rotating motor 41, a plurality of second rotating gears 43 and a plurality of first rotating gears 42.

The second rotating gears 43 have two specifications of large and small. The second rotating gears 43 are meshed and arranged between two adjacent first rotating gears 42. The rotating shaft of the rotating motor 41 is inserted into the gear cavity 25 and is coaxially and fixedly connected to one of the first rotating gears 42. Starting the rotating motor 41 drives the first rotating rollers 44 and the second rotating rollers 45 to rotate in the same direction and synchronously under the meshing of the gears, thereby driving the heat pipe to rotate through contact friction. The operation is simple and convenient, and it is convenient to use.

[0036] In order to further facilitate the use, referring to Figure 3 and Figure 4The gear cavity 25 extends into the base 1. The surface of the base 1 is provided with a moving groove 11. A moving block 3 is slidably provided in the moving groove 11. The top wall of the moving block 3 is flush with the top wall of the fixed block 2.

A transmission assembly 5 for transmission connection is provided between the moving block 3 and the rotating motor 41. The transmission assembly 5 includes a first transmission gear 52, a second transmission gear 53 and a transmission screw 51. The transmission screw 51 is rotatably provided in the moving groove 11 and threadedly penetrates the moving block 3. At the same time, the transmission screw 51 is inserted into the gear cavity 25. The first transmission gear 52 and the second transmission gear 53 are both rotatably provided in the gear cavity 25 and mesh with each other. The second transmission gear 53 is coaxially sleeved on the transmission screw 51. The first transmission gear 52 is meshed between the second transmission gear 53 and the first rotating gear 42 connected to the rotating shaft of the rotating motor 41. The heat pipe is inserted into the pushing groove 31 while being placed in the fixing groove 21. The rotating motor 41 rotates while the gear drives the transmission screw 51 to rotate, thereby driving the moving block 3 to move, thereby pushing the heat pipe to move. In conjunction with the rotation of the heat pipe and the spring contraction reset structure of the positioning rod 221, the positioning rod 221 can be automatically inserted into the heat pipe and rotated to position the heat pipe, further improving the convenience of use.

[0037] For easy loading, refer to Figure 1 , Figure 5 and Figure 6, two feeding seats 66 are fixedly arranged on the machine base 1. The top walls of the feeding seats 66 are flush with the top walls of the fixing block 2 and the moving block 3. A sliding groove 661 is arranged along the length direction on the top wall of the feeding seat 66. A sliding block 662 is slidably arranged in the sliding groove 661 in a matching manner. A sliding spring 663 in contact with the sliding block 662 is arranged in the sliding groove 661. A feeding block 6 connected to the sliding block 662 is slidably arranged on the surface of the feeding seat 66. A main feeding groove 61 is arranged on the surface of the feeding block 6. A plurality of auxiliary feeding grooves 62 communicating with the main feeding groove 61 are arranged on the bottom wall of the feeding block 6. The feeding block 6 can move above the fixing block 2 and the moving block 3, so that the auxiliary feeding grooves 62 are aligned with the pushing groove 31 and the position between the first rotating roller 44 and the second rotating roller 45. A first closing groove 63 and a second closing groove 64 are arranged on the inner wall of the auxiliary feeding groove 62. A first closing plate 631 inserted into the auxiliary feeding groove 62 is slidably arranged in the first closing groove 63 in a matching manner. A second closing plate 641 capable of being inserted into the auxiliary feeding groove 62 is slidably arranged in the second closing groove 64 in a matching manner. The first closing plate 631 is arranged below the second closing plate 641. The machine base 1 is provided with a driving assembly 7, and the driving assembly 7 is used to drive the first closing plate 631 and the second closing plate 641 to move. In another embodiment, auxiliary blocks capable of abutting against the bottom wall of the feeding block 6 are arranged in the area between the first rotating roller 44 and the second rotating roller 45 to improve the sliding stability of the feeding block 6. The heat pipes to be processed are all placed in the main feeding groove 61, and one heat pipe enters the auxiliary feeding groove 62 and closes the auxiliary feeding groove 62 to hold the heat pipe. The feeding block 6 is pushed to move above the fixing block 2, and the driving assembly 7 drives the first closing plate 631 to move so that the heat pipe falls into the fixing groove 21 and the pushing groove 31 for feeding. At the same time, the second closing plate 641 is inserted into the auxiliary feeding groove 62 to close the auxiliary feeding groove 62, reducing the possibility of other heat pipes falling and improving the convenience of feeding.

[0038] For convenient feeding, refer to Figure 5 and Figure 6, the driving assembly 7 includes a first driving gear 71, a first driving rack 73, a second driving rack 74, a second driving gear 72 and a third driving rack 75. The feeding block 6 is provided with a driving cavity 65 communicating with both the first closed groove 63 and the second closed groove 64 on one side of each feeding auxiliary groove 62 close to the fixed block 2. The first driving gear 71 and the second driving gear 72 are both rotatably arranged in the driving cavity 65. A plurality of auxiliary gears 78 engaged with each other are arranged in the driving cavity 65. The auxiliary gears 78 at both ends are respectively engaged with the first driving gear 71 and the second driving gear 72. The second driving rack 74 and the first driving rack 73 are meshed and arranged on the upper and lower sides of the first driving gear 71. The first driving rack 73 is fixedly connected with the first closing plate 631, and the second driving gear 72 is fixedly connected with the second closing plate 641. The third driving rack 75 is slidably arranged in the driving cavity 65 and meshes with the second driving gear 72. A protrusion is arranged on the inner wall of the driving cavity 65, and a return spring 79 connecting the protrusion and the third driving rack 75 is also arranged in the driving cavity 65. When it is necessary to drive the first closing plate 631 and the second closing plate 641, the third driving rack 75 is pushed to drive the second driving gear 72 to rotate. The first driving gear 71 is driven to rotate through the engagement of the auxiliary gears 78, so as to push the first closing plate 631 and the second closing plate 641 to move through the racks. At the same time, after the third driving rack 75 is released, the return spring 79 resets to push the third driving rack 75 and other components to reset. The operation is simple and convenient, which is convenient for feeding.

[0039] For further facilitating feeding, refer to Figure 3 and Figure 6 , the driving assembly 7 further includes a first driving rod 76 and a second driving rod 77. The bottom wall of the feeding block 6 is provided with a driving groove 651 communicating with the driving cavity 65. The first driving rod 76 is slidably arranged in the driving groove 651, and the length of the driving rod extending out of the bottom wall of the feeding block 6 is shorter as it is farther away from the sliding block 662. The first driving rod 76 extends into the driving cavity 65 and is connected with the third driving rack 75. The second driving rod 77 is fixedly arranged on the machine base 1 and is arranged between the fixed block 2 and the moving block 3. The height of the second driving rod 77 is lower as it is closer to the feeding base 66. The longer the extending length of the first driving rod 76, the lower the height of the second driving rod 77. During the process of moving the feeding block 6 above the fixed block 2, the first driving rod 76 abuts against the second driving rod 77 and drives the third driving rack 75 to move during the continuous movement, realizing feeding. The operation is simplified, which is further convenient for feeding.

[0040] For further facilitating use, refer to Figure 3, the machine base 1 is provided with a controller 8 that is signal - connected to both the rotating motor 41 and the pressing cylinder 241. A distance sensor 81 is embedded on the side wall of the second driving rod 77 close to the moving block 3. The distance sensor 81 is used to detect the distance between the second driving rod 77 and the moving block 3. The controller 8 is used to turn off the rotating motor 41 and start the pressing cylinder 241 according to the detection data of the distance sensor 81. After the moving block 3 moves and cooperates with the rotation of the heat pipe so that the positioning rod 221 is inserted into the heat pipe, the detection value of the distance sensor 81 is less than the set value. At this time, the controller 8 turns off the rotating motor 41 to stop the movement of the moving block 3 and the rotation of the heat pipe. At the same time, the controller 8 starts the pressing cylinder 241 to drive the pressing block 242 to move down for pressing and marking, which simplifies the operation and improves the convenience of heat pipe positioning and processing.

[0041] The implementation principle of a computer heat pipe processing and positioning device in an embodiment of this application is as follows: The heat pipes are all placed in the feeding main groove 61, and one heat pipe enters the feeding auxiliary groove 62 and is blocked by the first closing plate 631. During use, manually push the feeding block 6 to move above the fixed block 2 and the moving block 3. During this process, the first driving rod 76 and the second driving rod 77 are in one - to - one contact and abut against each other. The first driving rod 76 drives the third driving rack 75 to move, compress the return spring 79, and at the same time drives the second driving gear 72 to rotate. Through the auxiliary gear 78, the first driving gear 71 is driven to rotate, and through the first driving rack 73, the first closing plate 631 is driven to move out of the feeding auxiliary groove 62, so that the heat pipe in the feeding auxiliary groove 62 falls onto the pushing groove 31, the fixed groove 21, the first rotating roller 44, and the second rotating roller 45. At the same time, the second driving rack 74 drives the second closing plate 641 to insert into the feeding auxiliary groove 62 to block other heat pipes.

[0042] At this time, the rotation motor 41 is started. The rotation of the rotation motor 41 contacts and drives each first rotation gear 42 to rotate through the engagement with the second rotation gear 43, thereby driving the first rotation roller 44 and the second rotation roller 45 to rotate in the same direction and synchronously. Thus, the heat pipe is driven to rotate through contact friction. At the same time, the rotation of the transmission screw rod 51 is driven through the engagement of the first transmission gear 52 and the second transmission gear 53, so as to drive the moving block 3 to move closer to the fixed block 2, and the heat pipe is pushed to move above the abutting block 23 through the inner wall of the pushing groove 31. During this process, through the telescopic structure of the rotation of the heat pipe and the positioning spring 222, the positioning rod 221 is inserted into the heat pipe. Under the rotation of the heat pipe, the positioning rod 221 abuts against the capillary structure in the heat pipe, so that the heat pipe stops rotating in a fixed posture. At this time, the detection value of the distance sensor 81 reaches the set value, and the controller 8 stops the rotation motor 41 and starts the pressing cylinder 241. The pressing cylinder 241 drives the pressing block 242 to press down, and the marking is pressed on the heat pipe through the cooperation of the inserting block 243 and the abutting block 23. The marking position is relatively fixed with the position of the capillary structure, thereby completing the positioning processing of the heat pipe. The operation steps are less and multiple heat pipes can be marked at one time. Compared with manually confirming the positions one by one and manually marking, the convenience of the positioning processing of the heat pipe is improved.

[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
