[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0026] See also Figure 1-Figure 5 As shown, a device for non-destructively separating a hardware back plate from plastic comprises a hardware back plate 1 and a plastic ring 3. A separation component 2 is arranged on the periphery of the hardware back plate 1. The separation component 2 comprises a trapezoidal abutment block 201 arranged above the hardware back plate 1, a trapezoidal cover 202 is arranged below the trapezoidal abutment block 201, the trapezoidal abutment block 201 is adapted to the trapezoidal cover 202, a retaining ring 203 is fixedly installed at the bottom of the trapezoidal cover 202, an arc-shaped copper sheet 204 is fixedly installed on the inner wall of the retaining ring 203, a heating wire is arranged inside the arc-shaped copper sheet 204, the inner wall of the arc-shaped copper sheet 204 is abutted against the outer wall of the plastic ring 3, the retaining ring 203 is adapted to the outer shape of the plastic ring 3, a first sliding rheostat 205 is arranged below the hardware back plate 1, and the first sliding rheostat 205 is electrically connected to the heating wire in the arc-shaped copper sheet 204.
[0027] The clamp ring 203 is adapted to the plastic ring 3, so firstly, the clamp ring 203 is clamped on the outer wall of the plastic ring 3, so that the inner wall of the arc-shaped copper sheet 204 is against the outer wall of the plastic ring 3. When the trapezoidal abutment block 201 does not move, the slider on the first sliding rheostat 205 is located above the first sliding rheostat 205. At this time, the resistance is the smallest and the current is the largest, so the temperature of the heating wire in the arc-shaped copper sheet 204 is the highest.
[0028] When the trapezoidal abutment block 201 moves downward, the resistance becomes larger and larger as the scriber moves downward slowly, and the current becomes smaller, so the temperature of the heating wire also decreases. The change of the heat of the heating wire is adjusted by moving the trapezoidal abutment block 201 downward. The heat of the heating wire heats the arc-shaped copper sheet 204, and then the high temperature transmitted by the arc-shaped copper sheet 204 softens the side of the plastic ring 3 in contact with the arc-shaped copper sheet 204. Then the plastic ring 3 adheres to the inner wall of the arc-shaped copper sheet 204. At this time, the trapezoidal abutment block 201 continues to move downward, and the trapezoidal abutment block 201 squeezes the trapezoidal cover 202 to expand the trapezoidal cover 202 outward, thereby driving the clamping ring 203 to deflect outward.
[0029] When the clamping ring 203 shifts outward, the slider on the first sliding rheostat 205 also moves to the bottom of the first sliding rheostat 205. At this time, the heat of the heating wire in the arc-shaped copper sheet 204 has reached the lowest, so the plastic ring 3 will not continue to melt. Then the outward-expanding clamping ring 203 can break the plastic ring 3 off the trapezoidal resistance block 201.
[0030] See also Figure 2 A mounting plate 6 is fixedly mounted on the top of the trapezoidal resistance block 201 , a support rod 7 is fixedly mounted on the bottom of the mounting plate 6 , and the bottom end of the support rod 7 is connected to the scribe on the first sliding resistor 205 .
[0031] The mounting plate 6 moves downward together with the trapezoidal abutment block 201 , so when the mounting plate 6 moves up and down, it can drive the sliding piece on the first sliding rheostat 205 to move through the support rod 7 .
[0032] See also Figure 4 An arc-shaped fixing plate 9 is fixedly installed on the inner wall of the snap ring 203, an arc-shaped connecting plate 11 is arranged inside the snap ring 203, a plurality of springs 10 are installed between the outer wall of the arc-shaped connecting plate 11 and the inner wall of the arc-shaped fixing plate 9, a plurality of plug rods 12 are fixedly installed on the inner wall of the arc-shaped connecting plate 11, the plug rods 12 are plugged into the arc-shaped copper sheet 204, and the plug rods 12 are plugged into the plastic ring 3.
[0033] After the plastic ring 3 becomes soft, the insertion rod 12 will be inserted into the plastic ring 3 due to the squeezing of the spring 10 and the arc-shaped connecting plate 11. Then, when the retaining ring 203 expands outward, the insertion rod 12 can increase the contact area between the arc-shaped copper sheet 204 and the plastic ring 3, thereby preventing the arc-shaped copper sheet 204 from separating from the plastic ring 3 when the retaining ring 203 moves outward. The insertion rod 12 ensures that the plastic ring 3 can be successfully peeled off by the retaining ring 203.
[0034] See also Figure 1 and Figure 4A semiconductor cooling plate is arranged in the insertion rod 12, a second sliding rheostat 15 is arranged below the hardware back plate 1, a mounting rod 14 is fixedly installed at the bottom of the mounting plate 6, the bottom end of the mounting rod 14 is connected to the sliding piece on the second sliding rheostat 15, and the insertion rod 12 is electrically connected to the second sliding rheostat 15.
[0035] The second sliding rheostat 15 is opposite to the first sliding rheostat 205. When the slider on the second sliding rheostat 15 is located above the second sliding rheostat 15, the resistance is the largest. At this time, the cooling effect of the semiconductor refrigeration plate in the plug rod 12 is the lowest. When the surface of the plastic ring 3 gradually softens, the trapezoidal resistance block 201 moves downward, the mounting plate 6 drives the mounting rod 14 to move downward, and pushes the dicing piece on the second sliding rheostat 15 downward through the mounting rod 14. As the dicing piece on the second sliding rheostat 15 moves downward, the smaller the resistance, the larger the current, and the cooling effect of the semiconductor refrigeration plate in the plug rod 12 becomes stronger and stronger, which makes the plug rod 12 and the softened plastic ring 3 adhere more firmly.
[0036] See also Figure 1-Figure 2 A base plate 4 is arranged below the hardware back plate 1, the hardware back plate 1 is arranged on the top of the base plate 4, a hydraulic rod 8 is arranged above the base plate 4, and the telescopic end of the hydraulic rod 8 is connected to the bottom of the mounting plate 6.
[0037] The bottom plate 4 supports the hardware back plate 1 and connects the two fixed frames 5 below the hardware back plate 1, so that the fixed frames 5 can be used to support the first sliding rheostat 205 and the second sliding rheostat 15. The hydraulic rod 8 is used to drive the mounting plate 6 and the trapezoidal abutment block 201 to move up and down.
[0038] See also Figure 2 Two fixed frames 5 are fixedly installed on the outer wall of the bottom plate 4, the hydraulic rod 8 is fixedly installed on the top of one of the fixed frames 5, the first sliding rheostat 205 and the second sliding rheostat 15 are respectively installed on the inner walls of the two fixed frames 5, and the support rod 7 and the mounting rod 14 are both plugged into the fixed frame 5.
[0039] The fixed frame 5 supports the first sliding resistor 205 and the fixed frame 5, wherein one of the fixed frames 5 fixes the hydraulic rod 8 to make the hydraulic rod 8 more stable, and the support rod 7 and the mounting rod 14 are both plugged into the fixed frame 5 to ensure the movement effect of the support rod 7 and the mounting rod 14.
[0040] See also Figure 4 The arc-shaped copper sheet 204 is provided with a plurality of insertion holes 13 , the insertion rod 12 is located inside the insertion hole 13 , and the insertion rod 12 is slidably connected to the insertion hole 13 .
[0041] The multiple insertion holes 13 formed in the arc-shaped copper sheet 204 provide a space for the insertion rod 12 to be inserted, so that the insertion rod 12 can pass through the insertion holes 13 and be inserted into the plastic ring 3 .
[0042] See also Figure 1-Figure 5 , the trapezoidal cover 202 is made of elastic material.
[0043] The trapezoidal cover 202 made of elastic material can be deformed and expanded outward after being squeezed by the trapezoidal resistance block 201 .
[0044] Working principle:
[0045] The clamp ring 203 is adapted to the plastic ring 3, so firstly, the clamp ring 203 is clamped on the outer wall of the plastic ring 3, so that the inner wall of the arc-shaped copper sheet 204 is against the outer wall of the plastic ring 3. When the trapezoidal abutment block 201 does not move, the slider on the first sliding rheostat 205 is located above the first sliding rheostat 205. At this time, the resistance is the smallest and the current is the largest, so the temperature of the heating wire in the arc-shaped copper sheet 204 is the highest.
[0046] When the trapezoidal abutment block 201 moves downward, the resistance becomes larger and larger as the scriber moves downward slowly, and the current becomes smaller, so the temperature of the heating wire also decreases. The change of the heat of the heating wire is adjusted by moving the trapezoidal abutment block 201 downward. The heat of the heating wire heats the arc-shaped copper sheet 204, and then the high temperature transmitted by the arc-shaped copper sheet 204 softens the side of the plastic ring 3 in contact with the arc-shaped copper sheet 204. Then the plastic ring 3 adheres to the inner wall of the arc-shaped copper sheet 204. At this time, the trapezoidal abutment block 201 continues to move downward, and the trapezoidal abutment block 201 squeezes the trapezoidal cover 202 to expand the trapezoidal cover 202 outward, thereby driving the clamping ring 203 to deflect outward.
[0047] When the clamping ring 203 shifts outward, the slider on the first sliding rheostat 205 also moves to the bottom of the first sliding rheostat 205. At this time, the heat of the heating wire in the arc-shaped copper sheet 204 has reached the lowest, so the plastic ring 3 will not continue to melt. Then the outward-expanding clamping ring 203 can break the plastic ring 3 off the trapezoidal resistance block 201.
[0048] After the plastic ring 3 becomes soft, the insertion rod 12 will be inserted into the plastic ring 3 due to the squeezing of the spring 10 and the arc-shaped connecting plate 11. Then, when the retaining ring 203 expands outward, the insertion rod 12 can increase the contact area between the arc-shaped copper sheet 204 and the plastic ring 3, thereby preventing the arc-shaped copper sheet 204 from separating from the plastic ring 3 when the retaining ring 203 moves outward. The insertion rod 12 ensures that the plastic ring 3 can be successfully peeled off by the retaining ring 203.
