[0035] Example 1
[0036] Referring to Figures 1 to 5 The embodiment discloses a specific implementation of a radiator bottom cover removing device (hereinafter referred to as a removing device).
[0037] The radiator bottom cover removing device, referring to Figures 1 to 5 The removing device comprises a mechanical arm assembly 1, a clamping assembly 2 and a cover removing assembly 3. The clamping assembly 2 clamps the radiator 4 and makes the bottom cover 41 of the radiator 4 face downward. The cover removing assembly 3 comprises a support 31, a lifting cylinder 32, an upper clamping jaw 33 and a lower clamping jaw 34. The upper clamping jaw 33 is arranged at the top end of the support 31. The lifting cylinder 32 drives the lower clamping jaw 34 to lift or lower around the support 31. The bottom surface of the upper clamping jaw 33 is a first inclined surface 331. The end of the upper clamping jaw 33 is in the shape of a sheet. The top surface of the lower clamping jaw 34 is a second inclined surface 341. The first inclined surface 331 and the second inclined surface 341 are matched with each other. The first inclined surface 331 and the second inclined surface 341 are parallel to each other. The angle between the first inclined surface 331 and the horizontal plane is 10°-20°. The angle between the second inclined surface 341 and the horizontal plane is 10°-20°. The angle between the first inclined surface 331 and the horizontal plane is preferably 15°. The angle between the second inclined surface 341 and the horizontal plane is preferably 15°. When the mechanical arm assembly 1 drives the edge 411 of the bottom cover 41 of the radiator to the space between the first inclined surface 331 and the second inclined surface 341, the lifting cylinder 32 drives the lower clamping jaw 34 to move upward until the edge 411 is clamped.
[0038] Specifically, Figure 6 Fig. 1 is a schematic view of a radiator. The bottom of the radiator 4 is provided with a bottom cover 41. One side of the bottom cover 41 is provided with an edge 411. A gap is formed between the edge 411 and the bottom of the radiator. The bottom cover 41 is removed to expose silicone grease. The silicone grease is used to fill the narrow gap between the radiator 4 and the CPU. In order to automatically remove the bottom cover 41, the following steps are needed. First, the clamping assembly 2 clamps the radiator 4 and makes the bottom cover 41 of the radiator 4 face downward. Second, the mechanical arm assembly 1 drives the edge 411 of the bottom cover 41 of the radiator to the space between the first inclined surface 331 and the second inclined surface 341 and makes the end of the upper clamping jaw 33 penetrate into the edge 411. Third, the lifting cylinder 32 drives the lower clamping jaw 34 to move upward until the edge 411 is clamped. The clamping of the edge 411 is realized by the engagement between the first inclined surface 331 and the second inclined surface 341. That is, the clamping of the edge 411 is realized by the engagement between the upper clamping jaw 33 and the lower clamping jaw 34. Fourth, the mechanical arm assembly 1 moves upward and drives the radiator 4 to move upward. Since the edge 411 has been clamped, the radiator 4 is separated from the bottom cover 41 during the upward movement of the radiator 4.
[0039] Referring to Figure 3 and Figure 4In order to ensure the clamping of the edge 411, the second inclined surface 341 is rough, preferably a jagged rough surface, i.e. the surface of the second inclined surface 341 is provided with jagged lines, so that the edge 411 is clamped more tightly, and in the process of removing the bottom cover 41, the edge 411 is prevented from being separated.
[0040] Referring to Figures 2 to 5 The working principle of the clamping assembly 2 is as follows: the clamping assembly 2 includes a first clamping jaw 21 and a second clamping jaw 22, both of which are pneumatic clamping jaws, and the radiator 4 is clamped by the mutual approach between the first clamping jaw 21 and the second clamping jaw 22. In order to prevent displacement of the radiator 4 during cover removal, the bottom surface and the top surface of the radiator 4 need to be limited on the basis of the first clamping jaw 21 and the second clamping jaw 22 limiting both sides of the radiator. The bottom surface limiting structure of the radiator 4 is that the first clamping jaw 21 is provided with a first L-shaped step 211, the second clamping jaw 22 is provided with a second L-shaped step 221, and both sides of the bottom surface of the radiator 4 are supported on the first L-shaped step 211 and the second L-shaped step 221, respectively. Both sides of the bottom surface of the radiator 4 are supported by the bending of the first L-shaped step 211 and the second L-shaped step 221, respectively, to limit the displacement of the bottom surface of the radiator 4. The top surface limiting structure of the radiator 4 is that the end of the mechanical hand assembly 1 is provided with a fixed plate 11, four corners of the fixed plate 11 are respectively provided with a stand column 12, the stand column 12 is provided with a step 121, and a first spring 122 is arranged between the step 121 and the fixed plate 11. When the radiator 4 is clamped between the first clamping jaw 21 and the second clamping jaw 22, the top of the radiator is stopped by the stand column 12, i.e. the top surface of the radiator 4 is stopped by the four stand columns 12. In the process of moving the edge 411 of the radiator 4 between the first inclined surface 331 and the second inclined surface 341, and in the process of the edge 411 being in a clamped state and the radiator 4 being driven to rise, both sides, the bottom surface and the top surface of the radiator are limited, so that the radiator 4 will not be loose and displaced.
[0041] Referring to Figure 5, in the initial state when the edge 411 is clamped between the first inclined surface 331 and the second inclined surface 341, since the edge 411 is in a horizontal state, and the first inclined surface 331 and the second inclined surface 341 are not in a horizontal state clamping 411; after the heat sink 4 is lifted for a short distance, the bottom cover 41 is peeled off a little and bent, so that the edge 411 is slightly inclined, at this time the edge 411 is clamped between the first inclined surface 331 and the second inclined surface 341; the bottom of the cover dismounting assembly 3 is provided with a buffer structure, specifically, the cover dismounting assembly 3 further comprises a bottom plate 35, a plurality of buffer springs 36 are arranged above the bottom plate 35, the top of the buffer spring 36 is connected to the bottom of the bracket 31, the existence of the buffer spring 36 has the following two aspects of buffering effect, one is that in the process of sending the edge of the heat sink 4 between the first inclined surface 331 and the second inclined surface 341, the upper clamping jaw 33 may be subjected to downward pressure, if there is no buffer spring 36, the upper clamping jaw 33 may be bent, and the second is that in the process of the heat sink 4 rising, the existence of the buffer spring 36 makes the upward tension of the upper clamping jaw 33 also have elasticity, which can also reduce the possibility of the upper clamping jaw 33 being bent and deformed.
[0042] Referring to Figure 3 , in order to collect the dismounted bottom cover 4, the cover dismounting device is further provided with a bottom cover storage box 5; after the cover is dismounted, the lifting cylinder 32 descends, the lower clamping jaw 34 moves away from the upper clamping jaw 33, and the bottom cover 4 is free-falling into the bottom cover storage box 5, and the bottom cover 4 in the bottom cover storage box 5 can be cleaned after a period of time.
[0043] The mechanical arm assembly 1 has a rotating base and a plurality of movable arms, which can realize translation and lifting; through the embodiment, after the mechanical arm assembly 1 drives the clamping assembly 2 to clamp the heat sink 4, the cover dismounting assembly 3 is used to complete the dismounting of the cover, and the silicone grease at the bottom of the heat sink 4 is exposed; the mechanical arm assembly 1 drives the clamping assembly 2 to the upper side of the CPU, and after precise positioning by the CCD camera, the heat sink 4 and the CPU are assembled together; through the reciprocating movement, the heat sink 4 is automatically dismounted and assembled on the CPU, and the degree of automation is high, compared with manual operation, the CPU assembly efficiency is improved and the consistency is better.
[0044] Referring to Figure 2 and Figure 5, A label suction assembly 6 is further arranged on the side of the clamping assembly 2, the label suction assembly 6 comprises a vertical air cylinder 61, a horizontal plate 62, a first suction part 63 and a second suction part 64, the vertical air cylinder 61 drives the horizontal plate 62 to lift and drive the first suction part 63 and the second suction part 64 to suction or release the label; the first suction part 63 and the second suction part 64 are located at the two ends of the bottom of the horizontal plate 62, and the first suction part 63 and the second suction part 64 suction the two ends of the label; the first negative pressure port 621 and the second negative pressure port 622 are arranged on the horizontal plate 62, the first negative pressure port 621 is communicated with the first suction part 63, and the second negative pressure port 622 is communicated with the second suction part 64; in order to make the label keep a flat state, the label needs to be attached in the state of keeping negative pressure suction, if the negative pressure disappears in advance, the label position and the flatness of the label may be affected; the first suction part 63 and the second suction part 64 have a cavity, that is, the first suction part 63 and the second suction part 64 only suction a part of the surface area of the label, the sum of the suction areas of the first suction part 63 and the second suction part 64 is 1 / 3-1 / 2 of the surface area of the label, that is, only 1 / 3-1 / 2 of the surface area of the label is suctioned, the cavity can reduce the suction force of the first suction part 63 and the second suction part 64 on the label, when the label is attached to the surface of the assembled CPU module, the label is subjected to the sticking force between the CPU module and the first suction part 63 and the second suction part 64, when the sticking force is greater than the suction force, the label attaching action is completed.
