Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and specifically to an automatic assembly mechanism for sheet-like thermal conductive paste. Background Technology

[0002] In current industrial production, for fields requiring the assembly of paste-like viscous products, the market mainly relies on manual lines for manual peeling and assembly. However, during the manual peeling of pastes, such as sheet-like thermal grease, operators often find it difficult to precisely control the peeling force and angle, which can easily damage the paste-like viscous products, such as tearing, deformation, or contamination. Secondly, during the assembly process, manual operation carries the risk of omissions, incorrect assembly, and large assembly accuracy errors, which in turn affect production efficiency and reduce product qualification rates.

[0003] Therefore, this application studies an automatic assembly mechanism for sheet-like thermal conductive paste, which can improve production efficiency and ensure product qualification rate. Utility Model Content

[0004] In order to improve production efficiency and ensure product qualification rate, this application provides an automatic assembly mechanism for sheet-shaped thermal conductive paste.

[0005] This application provides an automatic assembly mechanism for sheet-like thermal conductive paste, which adopts the following technical solution:

[0006] An automatic assembly mechanism for sheet-shaped thermal conductive paste includes a three-axis module and a material handling mechanism. The three-axis module drives the material handling mechanism to move along the X-axis, Y-axis, and Z-axis directions. The material handling mechanism includes a suction component, a suction drive component, an air blowing component, and an air blowing drive component. The suction component is used to suction the sheet-shaped thermal conductive paste, and the suction drive component drives the suction component to move along the Z-axis direction towards or away from the sheet-shaped thermal conductive paste. The air blowing component is used to press the sheet-shaped thermal conductive paste, and the air blowing drive component drives the air blowing component to move along the Z-axis direction towards or away from the sheet-shaped thermal conductive paste.

[0007] By adopting the above technical solution, the three-axis module moves and positions itself along the X and Y axes, ensuring that the material handling mechanism and vision inspection mechanism can accurately reach the designated working position. The Z-axis movement is used for vertical control, allowing the material handling mechanism to move closer to or away from the sheet thermal paste. When the material handling mechanism approaches the sheet thermal paste, the suction drive drives the suction component to move vertically to the sheet thermal paste, which is then sucked up. The air blowing drive drives the air blowing component to move vertically to the adjacent sheet thermal paste, applying pressure by blowing air. This causes the suction drive to move upward, separating the sheet thermal paste from the adjacent sheet thermal paste, preventing the adjacent sheet thermal paste from being lifted up. Then, the three-axis module moves the sheet thermal paste to the corresponding position for assembly, thereby improving production efficiency, reducing errors caused by manual operation, and ensuring the product qualification rate.

[0008] Optionally, a floating connector is provided between the output end of the suction drive and the suction member, and / or a floating connector is provided between the output end of the blowing drive and the blowing member.

[0009] Optionally, it may also include an R-axis module, which drives the material handling mechanism to rotate along the R-axis.

[0010] By adopting the above technical solution, the R-axis rotates in the circumferential direction, eliminating the angular error caused by the discharge of sheet-like thermal paste.

[0011] Optionally, the R-axis module includes a first driving component, a first synchronous pulley, a second synchronous pulley, a rotating shaft, and a belt. The output end of the first driving component is connected to the first synchronous pulley. The rotating shaft is mounted on the second synchronous pulley, and one end is connected to the material handling mechanism. The belt is sleeved on the first synchronous pulley and the second synchronous pulley. The first driving component drives the first synchronous pulley to rotate through the belt, thereby driving the material handling mechanism to rotate.

[0012] Optionally, it also includes a mounting base connected to the three-axis module, the three-axis module driving the mounting base to move along the Z-axis, and the R-axis module mounted on the mounting base; the material handling mechanism also includes a rotating base, the rotating shaft connected to the rotating base, and both the suction drive and the blowing drive are mounted on the rotating base.

[0013] Optionally, it also includes an origin sensor, wherein a sensing plate is provided on the rotating shaft, and the sensing plate moves closer to or away from the origin sensor as the rotating shaft rotates.

[0014] The above technical solution is used to determine whether the transmission of the first driving component has returned to the origin.

[0015] Optionally, it also includes an induced check valve, which is installed at the end of the second synchronous pulley away from the material handling mechanism.

[0016] The above technical solution is used to supply air to the R-axis module downwards.

[0017] Optionally, a vision inspection mechanism is also included, which is disposed on one side of the material handling mechanism, and the three-axis module drives the vision inspection mechanism to move along the X-axis, Y-axis and Z-axis directions.

[0018] By adopting the above technical solution, AIO detection is used to detect the initial position and post-assembly position of the product and to determine whether the product has any missing parts.

[0019] Optionally, it also includes a digital pressure gauge that displays the vacuum value for drawing the sheet-like thermal grease.

[0020] Optionally, the three-axis module is provided with drag chains along the X-axis, Y-axis and Z-axis directions.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. The three-axis module moves and positions itself along the X and Y axes, ensuring that the material handling mechanism and vision inspection mechanism can accurately reach the designated working position. The Z-axis movement is used for vertical control, allowing the material handling mechanism to move closer to or away from the sheet thermal paste. When the material handling mechanism approaches the sheet thermal paste, the suction drive moves the suction component vertically to the sheet thermal paste, and the suction component picks it up. The blowing drive moves the blowing component vertically to the adjacent sheet thermal paste, and the blowing applies pressure to the adjacent sheet thermal paste, causing the suction drive to move upward and peel the sheet thermal paste from the adjacent sheet thermal paste, preventing the adjacent sheet thermal paste from being lifted up. Then, the three-axis module moves the sheet thermal paste to the corresponding position for assembly, thereby improving production efficiency, reducing errors caused by manual operation, and ensuring the product qualification rate.

[0023] 2. The R-axis rotates, i.e., rotates in a circular direction, to eliminate the angular error caused by the dispensing of sheet-like thermal paste;

[0024] 3. Visual inspection agencies are used to detect the initial and post-assembly positions of products using AIO (Automatic Inspection) and to determine if any parts of the product are missing. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0031] This application discloses an automatic assembly mechanism for sheet-like thermal conductive paste. (Refer to...) Figure 1 The automatic assembly mechanism for sheet-shaped thermal paste includes a three-axis module 1 and a material-picking mechanism 2. The three-axis module 1 includes an X-axis module 11, a Y-axis module 12, and a Z-axis module 13, which respectively drive the material-picking mechanism 2 to move along the X-axis, Y-axis, and Z-axis directions. Specifically, the X-axis module 11, Y-axis module 12, and Z-axis module 13 are all linear modules. The X-axis module 11 is slidably mounted on the Y-axis module 12, the Z-axis module 13 is slidably mounted on the X-axis module 11, and the material-picking mechanism 2 is mounted on the Z-axis module 13. The Y-axis module 12 drives the X-axis module 11 to move the Z-axis module 13 and the material-picking mechanism 2 along the Y-axis direction. The X-axis module 11 drives the Z-axis module 13 to move the material-picking mechanism 2 along the X-axis direction, and the Z-axis module 13 drives the material-picking mechanism 2 to move along the Z-axis direction, thereby realizing the three-axis movement of the material-picking mechanism 2.

[0032] Reference Figure 2 The material handling mechanism 2 includes a suction member 21, a suction drive member 22, an air blowing member 23, and an air blowing drive member 24. The suction member 21 is used to pick up sheet-like thermal conductive paste. The suction member 21 is connected to an external vacuum device, which evacuates the suction member 21 to pick up the sheet-like thermal conductive paste. The suction drive member 22 drives the suction member 21 to move along the Z-axis towards or away from the sheet-like thermal conductive paste. In this embodiment, the suction drive member 22 is a telescopic cylinder. After the suction member 21 is brought close to the sheet-like thermal conductive paste and picked up by the vacuum device, the suction member 21 is then driven to carry the sheet-like thermal conductive paste to the product assembly.

[0033] The air blowing component 23 is used to press the sheet-like thermal grease. The air blowing component 23 is connected to an external air blowing device. The external air blowing device causes the air blowing component 23 to blow air onto the adjacent sheet-like thermal grease, thereby applying downward pressure to the adjacent sheet-like thermal grease and preventing it from being lifted up. This allows for better peeling of the sheet-like thermal grease and ensures the peeling quality of the sheet-like thermal grease. The method of suction and blowing also better protects the sheet-like thermal grease. Here, "adjacent sheet-like thermal grease" refers to the sheet-like thermal grease adjacent to the sheet-like thermal grease that needs to be suctioned.

[0034] The air-blowing drive 24 drives the air-blowing component 23 to move along the Z-axis towards or away from the sheet-like thermal grease. In this embodiment, the air-blowing drive 24 is a telescopic cylinder that drives the air-blowing component 23 to approach the adjacent sheet-like thermal grease and apply pressure by blowing air. After the sheet-like thermal grease is sucked away, the air-blowing component 23 is driven away from the adjacent sheet-like thermal grease. Finally, the three-axis module 1 drives the sheet-like thermal grease to the assembly position for assembly, thereby improving production efficiency, reducing errors caused by manual operation, and ensuring the product qualification rate.

[0035] In some embodiments, a floating connector 3 is provided between the output end of the suction drive 22 and the suction member 21, and / or a floating connector 3 is provided between the output end of the blowing drive 24 and the blowing member 23. In this embodiment, both the output ends of the suction drive 22 and the blowing drive 24 are provided with floating connectors 3, which can ensure the stability and reliability of the suction member 21 and the blowing member 23.

[0036] Continue to refer to Figure 2 In some embodiments, the automatic assembly mechanism for sheet thermal paste further includes an R-axis module 4, which drives the material handling mechanism 2 to rotate along the R-axis. The R-axis rotation is a horizontal circumferential rotation. The angle of the suction mechanism is adjusted by the R-axis rotation to eliminate the angle error caused by the sheet thermal paste being discharged.

[0037] In some embodiments, the R-axis module 4 includes a first drive member 41, a first synchronous pulley 42, a second synchronous pulley 43, a rotating shaft 44, and a belt. The first drive member 41 is a motor, and the output end of the motor is connected to the first synchronous pulley 42, driving the first synchronous pulley 42 to rotate. The rotating shaft 44 is mounted on the second synchronous pulley 43, and one end is connected to the material picking mechanism 2. The belt is sleeved on the first synchronous pulley 42 and the second synchronous pulley 43. The first drive member 41 drives the first synchronous pulley 42 to rotate through the belt, thereby driving the material picking mechanism 2 to rotate through the rotating shaft 44, so that the material picking mechanism 2 can rotate stably.

[0038] Cooperate Figure 1In some embodiments, the automatic assembly mechanism for sheet-like thermal paste further includes a mounting base 5, which is connected to a triaxial module 1. The triaxial module 1 drives the mounting base 5 to move along the Z-axis. In this embodiment, the mounting base 5 is mounted on a Z-axis module 13, and the Z-axis module 13 drives the mounting base 5 to move along the Z-axis. An R-axis module 4 is mounted on the mounting base 5, and the movement of the mounting base 5 drives the movement of the R-axis module 4. (Continue referring to...) Figure 2 The material handling mechanism 2 also includes a rotating base 25, to which a rotating shaft 44 is connected. The rotating shaft 44 drives the rotating base 25 to move. The suction drive 22 and the air blowing drive 24 are both screwed onto the rotating base 25. That is, the mounting base 5 can move along the Z-axis to drive the R-axis module 4 and the material handling mechanism 2 to move along the Z-axis. The R-axis module 4 can then drive the material handling module to rotate. In this embodiment, the mounting base 5 is also provided with a fixing plate 6. The rotating shaft 44 passes through and is rotatably connected to the fixing plate 6 before being connected to the rotating base 25, so that the rotating shaft 44 can stably drive the rotating base 25 to rotate.

[0039] In some embodiments, the automatic assembly mechanism for sheet-like thermal paste further includes an origin sensor 7, and a sensing plate 8 is provided on the rotating shaft 44. The sensing plate 8 rotates with the rotating shaft 44 and moves closer to or further away from the origin sensor 7. The position of the sensing plate 8 can determine whether the motor has rotated back to the origin.

[0040] In some embodiments, the automatic assembly mechanism for sheet-like thermal paste further includes an induction check valve 9, which is installed at one end of the second synchronous wheel 43 away from the material handling mechanism 2, and is used to supply air to the R-axis module 4 downward.

[0041] Refer again Figure 1 In some embodiments, the automatic assembly mechanism for sheet thermal paste also includes a vision inspection mechanism 10. The vision inspection mechanism 10 is disposed on one side of the material handling mechanism 2. The three-axis module 1 drives the vision inspection mechanism 10 to move along the X-axis, Y-axis and Z-axis directions. In this embodiment, the vision inspection mechanism 10 is also screwed onto the mounting plate and is used to detect the initial position and post-assembly position of the product (AIO detection) and to determine whether the product has any missing parts.

[0042] The visual inspection mechanism 10 in this embodiment also includes a camera and a light source. The camera captures the initial position and related information, and the light source illuminates the product to facilitate image capture by the camera.

[0043] In some embodiments, the automatic assembly mechanism for sheet thermal paste further includes a digital pressure gauge 14, which displays the vacuum value for drawing the sheet thermal paste.

[0044] In some embodiments, the three-axis module 1 is provided with cable carriers 15 along the X-axis, Y-axis and Z-axis directions. That is, the X-axis module 11, Y-axis module 12 and Z-axis module 13 are all provided with cable carriers 15 for cable protection.

[0045] The implementation principle of the automatic assembly mechanism for sheet thermal paste in this application embodiment is as follows: the three-axis module 1 moves and positions itself along the X and Y axes to ensure that the picking mechanism 2 and the vision inspection mechanism 10 can accurately reach the designated working position. The movement of the Z axis is used for vertical control, so that the picking mechanism 2 moves closer to or away from the sheet thermal paste. When the picking mechanism approaches the sheet thermal paste, the suction drive 22 drives the suction component 21 to move vertically to the sheet thermal paste. The suction component 21 picks up the paste, and the blowing drive 24 drives the blowing component 23 to move vertically to the adjacent sheet thermal paste. The blowing component presses the adjacent sheet thermal paste with a certain pressure, so that the suction drive 22 moves upward to separate the sheet thermal paste from the adjacent sheet thermal paste, avoiding the adjacent sheet thermal paste being lifted up. Then, the three-axis module 1 moves the sheet thermal paste to the corresponding position for assembly, thereby improving production efficiency, reducing errors caused by manual operation, and ensuring the product qualification rate.
