Description

Technical Field

[0001] This utility model relates to the field of applying thermal grease, and in particular to an automatic thermal grease application assembly for optical modules. Background Technology

[0002] Thermal grease, commonly known as heat dissipation paste, is a highly thermally conductive and insulating silicone material. It is made primarily from silicone, with added heat-resistant and thermally conductive materials to form a thermally conductive silicone grease-like compound. It is used for heat conduction and dissipation in electronic components such as power amplifiers, transistors, electron tubes, and CPUs, thereby ensuring the stability of the electrical performance of electronic instruments and meters.

[0003] Thermal grease is usually in the form of paste or gruel and has a certain degree of viscosity. It is weakly viscous and can adhere well to the product surface, making it easy to apply and install. Thermal grease sheets are made from thermal grease and are attached to the backing paper. Due to the aforementioned characteristics of thermal grease, it is not easy to transfer or collect. Excessive force will deform the thermal grease, while insufficient force will make it difficult to grasp. The thermal grease sheet is not easy to separate from the backing paper. In short, collecting thermal grease sheets is difficult. Utility Model Content

The steering plate is rotatably disposed within the steering space. The steering plate is connected to the drive end of the material shoveling cylinder, and the silicone grease shovel is disposed on the steering plate. The grease spatula is configured such that when the adsorption hole adsorbs thermal grease, the grease spatula rotates to scoop up the thermal grease. Under the indirect drive of the four-axis robot, the adsorption block moves to the set position, the grease spatula rotates away from the thermal grease, and the adsorption hole exhales air to adhere to the thermal grease.

[0008] Optionally, the suction mechanism further includes a sliding frame connected to the conversion plate, the sliding frame being slidably disposed on the connecting plate, and the two ends of the elastic column being connected to the sliding frame and the suction block, respectively.

[0009] Furthermore, the suction mechanism also includes a snap-fit ​​block and a limiting block.

The limiting block is disposed on the side wall of the slide frame and has a guide hole. The suction block is slidably disposed in the guide hole. The two ends of the elastic column are respectively connected to the snap-fit ​​block and the suction block.

[0010] Furthermore, the bottom end of the limiting block has a guide strip, and the guide strip is provided with a guide groove.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model relates to an automatic thermal grease applicator for optical modules. Because thermal grease is sticky and often adheres to the backing paper when it's applied to the adsorption holes, the grease spatula is rotated to scoop it up. This prevents the grease from simultaneously sticking to both the second end of the adsorption hole and the backing paper, making separation easier. Furthermore, during the adsorption and transport process, the grease spatula also supports the grease, preventing it from falling off the second end of the adsorption hole. Therefore, this invention solves the problem of difficult grease pickup. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figure 1 and Figure 2 and Figure 3As shown, the automatic thermal grease application assembly for optical modules includes a drive mechanism 1, a suction mechanism 2, and a scraping mechanism 3. The drive mechanism 1 includes a four-axis robot 11, the suction mechanism 2 is used to absorb the thermal grease, and the scraping mechanism 3 is used to scoop up and lift the thermal grease.

[0022] The suction mechanism 2 includes a connecting plate 21, a suction cylinder 22, a conversion plate 23, an elastic column 24, a suction block 25, and a sliding frame 28. The connecting plate 21 is connected to the drive end of the four-axis robot 11. The suction cylinder 22 is mounted on the connecting plate 21 and is fixed to the connecting plate 21 by bolts. The conversion plate 23 is connected to the drive end of the suction cylinder 22. The sliding frame 28 is mounted on the conversion plate 23. The two ends of the elastic column 24 are connected to the sliding frame 28 and the suction block 25, respectively. The suction block 25 is connected to an external air pump (not shown in the figure). The suction block 25 is provided with a suction hole 26. The first port of the suction hole 26 is connected to the air pump (not shown in the figure), and the second port of the suction hole 26 is used to absorb thermal conductive grease.

[0023] The adsorption cylinder 22 drives the conversion plate 23 to move, the conversion plate 23 drives the slide frame 28 to move, the elastic column 24 and the adsorption block 25 follow the slide frame 28 to move. When the second port of the adsorption hole 26 is attached to the thermal grease, the elastic column 24 is elastic and plays a buffering role to prevent the bottom end of the adsorption block 25 from deforming or thinning the thermal grease. In this example, the elastic column 24 is a rubber column.

[0024] The grease spatula 35 is configured such that when the adsorption hole 26 adsorbs thermal grease, the grease spatula 35 rotates to scoop up the thermal grease. Under the indirect drive of the four-axis robot 11, the adsorption block 25 moves to the set position, the grease spatula 35 rotates away from the thermal grease, and the adsorption hole 26 releases the thermal grease.

[0025] The four-axis robot 11, the suction cylinder 22, and the shoveling cylinder 31 are all connected to the PLC controller (not shown in the figure). After the position of the thermal grease is determined, the PLC controller sends a command to the four-axis robot 11, which drives the suction mechanism 2 to move so that the suction block 25 is positioned above the thermal grease and the second port of the suction hole 26 is aligned with the thermal grease. The four-axis robot 11 then stops driving the suction mechanism 2 to move. The PLC controller sends a command to the suction cylinder 22, which indirectly drives the suction block 25 to descend to the set height so that the second port of the suction hole 26 is in contact with the thermal grease. Then, the air pump is turned on, and the air pump draws air through the first port of the suction hole 26. The second port of the suction hole 26 then begins to absorb the thermal grease.

[0026] At the same time, the PLC controller sends a command to the shovel cylinder 31, which indirectly drives the grease shovel 35 to rotate. The end of the grease shovel 35 shovels the thermal grease from the backing paper, thus separating the thermal grease from the backing paper. The grease shovel 35 lifts up the thermal grease. When the grease shovel 35 rotates to the set position, the shovel cylinder 31 stops driving the grease shovel 35 to rotate.

[0027] The PLC controller then sends a command to the adsorption cylinder 22, which indirectly drives the adsorption block 25 to reset. This causes the scraping mechanism 3 and the thermal grease to move together with the adsorption block 25. Then, the adsorption cylinder 22 stops driving the adsorption block 25 to move. The PLC controller then sends a command to the four-axis robot 11, which drives the suction mechanism 2 to move. This causes the scraping mechanism 3 and the thermal grease to move together with the adsorption block 25 until the adsorption block 25 moves to the set position, so that the thermal grease is directly above the item to be applied.

[0028] The PLC controller then sends instructions to the adsorption cylinder 22 and the scraping mechanism 3. The adsorption cylinder 22 indirectly drives the adsorption block 25 to descend, and the scraping mechanism 3 indirectly drives the silicone grease shovel 35 to reverse and reset. At the same time, the air pump blows air in reverse, causing the thermal grease to detach from the first port of the adsorption hole 26. With the assistance of the air pump blowing air in reverse, the thermal grease is applied to the item to be applied. Then, the adsorption cylinder 22 indirectly drives the adsorption block 25 to reset, thus completing the transfer and application of the thermal grease.

[0029] The four-axis robot 11 has a drive rod 12 at its drive end. The drive mechanism 1 also includes a coupling 13. The drive rod 12 is connected to the coupling 13. A conversion head 4 is provided on the coupling 13. An adapter 27 is provided on the connecting plate 21. The adapter 27 is connected to the conversion head 4. The suction mechanism 2 is connected to the conversion head 4 through the adapter 27. Because the thermal grease size is different, different suction mechanisms 2 can be replaced as needed. The conversion head 4 is suitable for different models of suction mechanisms 2.

[0030] The drive mechanism 1 also includes a lampshade 14, a third vision detector 15, and a square light 16. The lampshade 14 is mounted on the coupling 13, and the four-axis robot 11 indirectly drives the coupling 13 to rotate. The third vision detector 15 is mounted inside the lampshade 14, and the square light 16 is mounted at the bottom of the lampshade 14. The imaging end of the third vision detector 15 is aligned with the center of the square light 16, and the imaging end of the third vision detector 15 is located at the outer edge of the lampshade 14. The square light 16 is used to increase the brightness of the thermal grease and assist the third vision detector 15 in positioning and detecting the thermal grease to be adsorbed.

[0031] The third vision detector 15 is connected to the PLC controller. The third vision detector 15 takes a picture of the thermal grease to be adsorbed and then sends the detection result to the PLC controller to determine the position of the thermal grease to be adsorbed. Then, the PLC controller first sends a command to the four-axis robot 11. The four-axis robot 11 first drives the lamp cover 14 to rotate, so that the third vision detector 15 and the square lamp 16 are away from the thermal grease to be adsorbed. Then, the four-axis robot 11 indirectly drives the suction mechanism 2 to move, so that the adsorption block 25 is positioned above the thermal grease to be adsorbed and the second port of the adsorption hole 26 is aligned with the thermal grease to be adsorbed. The PLC controller sends a command to the adsorption cylinder 22, and the adsorption cylinder 22 indirectly drives the adsorption block 25 to descend to a set height, so that the second port of the adsorption hole 26 is in contact with the thermal grease.

[0032] The PLC controller sends a command to the shovel cylinder 31, which indirectly drives the grease shovel 35 to rotate. At the same time, the air pump is turned on and draws air from the first port of the adsorption hole 26. In this way, the second port of the adsorption hole 26 begins to adsorb the thermal grease to be adsorbed, and the grease shovel 35 scoops up the thermal grease to be adsorbed.

[0033] If the thermal grease to be adsorbed detected by the third vision detector 15 is unqualified, the PLC controller sends a command to the four-axis robot 11, which indirectly drives the third vision detector 15 to move, so that the third vision detector 15 can continue to detect the thermal grease to be adsorbed.

[0034] like Figure 4 As shown, the material shoveling mechanism 3 includes a material shoveling cylinder 31, a panel 33, a steering plate 34, and a silicone grease shovel 35. The steering plate 34 is rotatably disposed in the steering space 36. The steering plate 34 is connected to the drive end of the material shoveling cylinder 31. The silicone grease shovel 35 is disposed on the steering plate 34 and is fixed to the bottom end of the steering plate 34 by bolts.

[0035] The shovel cylinder 31 drives the steering plate 34 to rotate, the steering plate 34 drives the silicone grease shovel 35 to rotate, the steering plate 34 rotates in the steering space 36, and the rotation of the silicone grease shovel 35 can shovel up the thermal grease on the base paper.

[0036] The sliding frame 28 includes an integrally formed first side plate 281, second side plate 282 and third side plate 283. The first side plate 281 and the second side plate 282 are respectively connected to the first side plate 281 and the second side plate 282 at both ends of the second side plate 282. The second side plate 282 is connected to the first side plate 281 and the second side plate 282 by bolts. The first side plate 281 is slidably mounted on the connecting plate 21. The first side plate 281 is mounted on the connecting plate 21 by a slider and a slide rail. The conversion plate 23 is mounted on the second side plate 282. The panel 33 is mounted on the third side plate 283. The two ends of the elastic column 24 are respectively connected to the second side plate 282 and the adsorption block 25. The panel 33 is mounted on the third side plate 283. A turning space 36 is formed between the panel 33 and the third side plate 283.

[0037] Furthermore, the conversion plate 23 includes an integrally formed first base plate 231 and a fourth side plate 232. When the adsorption cylinder 22 drives the first base plate 231 to move, the first base plate 231 drives the fourth side plate 232 to move, and the fourth side plate 232 drives the first side plate 281, the second side plate 282 and the third side plate 283 to move. The first side plate 281 slides on the connecting plate 21, the second side plate 282 drives the elastic column 24 and the adsorption block 25 to move, and the third side plate 283 drives the panel 33 to move.

[0038] like Figure 7 As shown, the first base plate 231 is connected to the drive end of the adsorption cylinder 22, the second side plate 282 is provided with a side plate groove 284, the fourth side plate 232 is provided in the side plate groove 284, and the fourth side plate 232 is fixed to the second side plate 282 by bolts. The first side plate 281 and the adsorption cylinder 22 are respectively provided on both sides of the connecting plate 21, and the adsorption cylinder 22 is also located between the third side plate 283 and the connecting plate 21.

[0039] like Figure 5 and Figure 6 As shown, the suction mechanism 2 also includes a snap-fit ​​block 29 and a limiting block 201. The snap-fit ​​block 29 is disposed on the upper end of the second side plate 282 and is fixed to the upper end of the second side plate 282 by bolts. The snap-fit ​​block 29 extends to the outer edge of the second side plate 282 and is wider than the width of the second side plate 282 in the vertical direction. The limiting block 201 is disposed on the side wall of the second side plate 282 and is fixed to the side wall of the second side plate 282 by bolts. The limiting block 201 is provided with a guide hole 202. The suction block 25 is slidably disposed in the guide hole 202 and is longer than the guide hole 202. The two ends of the elastic column 24 are respectively connected to the snap-fit ​​block 29 and the suction block 25.

[0040] Furthermore, the adsorption block 25 includes an overlapping portion 252 and a main body portion 253 connected together. The elastic column 24 is connected to the snap-fit ​​block 29 and the overlapping portion 252 at both ends respectively. The overlapping portion 252 can overlap the upper end of the limiting block 201 and the radial outer edge of the top end of the guide hole 202. In this way, the height of the adsorption block 25 falling is limited by the limiting block 201, and the main body portion 253 is slidably disposed in the guide hole 202.

[0041] The bottom end of the limiting block 201 has a guide strip 203, and a guide groove 204 is provided on the guide strip 203. The guide groove 204 is axially connected to the guide hole 202. The bottom end of the adsorption block 25 has an adsorption strip 251. The second opening of the adsorption hole 26 is located at the bottom end of the adsorption strip 251. The adsorption strip 251 is slidably disposed in the guide groove 204.

[0042] The adsorption strip 251 is located at the bottom of the main body 253. When the adsorption block 25 is lowered to a set height to adsorb the thermal grease, the adsorption strip 251 will adhere to the thermal grease until the bottom of the adsorption strip 251 is in contact with the thermal grease, so that the second port of the adsorption hole 26 adsorbs the thermal grease.

[0043] The material shoveling mechanism 3 also includes a first connecting rod 301 and a second connecting rod 302. The axial ends of the first connecting rod 301 and the axial ends of the second connecting rod 302 are respectively connected to the third side plate 283 and the panel 33. In this example, the axial ends of the first connecting rod 301 and the axial ends of the second connecting rod 302 are respectively connected to the third side plate 283 and the panel 33.

[0044] The material scraping mechanism 3 also includes a drive shaft 37. The panel 33 is provided with an arc-shaped hole 38. The two ends of the drive shaft 37 are respectively connected to the drive end of the material scraping cylinder 31 and the steering plate 34. The drive shaft 37 passes through and slides in the arc-shaped hole 38. The drive end of the material scraping cylinder 31 is rotatably connected to the drive shaft 37. The material scraping cylinder 31 drives the drive shaft 37 to move. The drive shaft 37 moves in the arc-shaped hole 38. In fact, the drive shaft 37 rotates in the arc-shaped hole 38. In this way, the steering plate 34 and the silicone grease scraper 35 rotate.

[0045] When the thermal grease is adsorbed at the second port of the adsorption hole 26, the shovel cylinder 31 indirectly drives the grease shovel 35 to rotate, so that the grease shovel 35 scoops up the thermal grease. Then, when the adsorption block 25 and the thermal grease move upward, the shovel cylinder 31 continues to indirectly drive the grease shovel 35 to rotate until the grease shovel 35 abuts the bottom of the guide strip 203. In this way, the adsorption block 25 and the elastic column 24 will retract. When the adsorption block 25 moves above the item to be applied, the shovel cylinder 31 indirectly drives the grease shovel 35 to rotate and reset.

[0046] The material shoveling mechanism 3 also includes a first rotating shaft 303, a second rotating shaft 304, and a third rotating shaft 305. The two axial ends of the first rotating shaft 303, the two axial ends of the second rotating shaft 304, and the two axial ends of the third rotating shaft 305 are respectively connected to the third sliding plate 283 and the panel 33. In this example, the two axial ends of the first rotating shaft 303, the two axial ends of the second rotating shaft 304, and the two axial ends of the third rotating shaft 305 are respectively connected to the third side plate 283 and the panel 33. The steering plate 34 is provided with a first steering hole 307, a second steering hole 308, and a third steering hole 309. The first rotating shaft 303 passes through and slides in the first steering hole 307, the second rotating shaft 304 passes through and slides in the second steering hole 308, and the third rotating shaft 305 passes through and slides in the third steering hole 309.

[0047] The first steering hole 307, the second steering hole 308, and the third steering hole 309 have the same curvature and length as the arc hole 38. The steering plate 34 rotates around the first rotating shaft 303, the second rotating shaft 304, and the third rotating shaft 305. That is, the first rotating shaft 303 rotates relative to the first steering hole 307, the second rotating shaft 304 rotates relative to the second steering hole 308, and the third rotating shaft 305 rotates relative to the third steering hole 309.

[0048] The first rotating shaft 303, the second rotating shaft 304, and the third rotating shaft 305 are arranged on the steering plate 34. The second rotating shaft 304 is located between the first rotating shaft 303 and the third rotating shaft 305. The center lines of the first rotating shaft 303, the second rotating shaft 304, and the third rotating shaft 305 are on the same straight line.

[0049] The material shoveling mechanism 3 also includes a mounting base 32, which is mounted on the panel 33. The material shoveling cylinder 31 is mounted on the mounting base 32. The mounting base 32 is fixed to the panel 33 by bolts. Rotating the mounting base 32 can adjust the driving direction of the material shoveling cylinder 31.
