Description

Technical Field

[0001] The present invention relates to the technical field of copper clad laminate detection, and particularly to a device for detecting the surface flatness of a copper clad laminate. Background Art

[0002] Copper clad laminates are mainly used for processing and manufacturing circuit boards and are the basic materials of the electronics industry. After the production of copper clad laminates, people will conduct a series of inspections on them, including surface flatness inspection. The flatness of the surface of the copper clad laminate determines the manufacturing quality of the circuit board. People usually use inspection equipment to detect the surface of the copper clad laminate. However, the existing inspection devices still have the following problems when in use: The existing inspection devices will clamp the copper clad laminate when in use, but the clamping components are difficult to clamp copper clad laminates of different sizes, which makes it inconvenient to detect copper clad laminates of different sizes and difficult to meet people's usage requirements. Therefore, we need to design an inspection device.

[0062] Embodiment 1

[0063] A surface flatness detection device for copper clad laminates, now referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 6 , including a base 1, a fixing frame 2, a placing frame 3, a telescopic frame 4, a degree meter 5, a detector 6, a fixing rod 7, a first compression spring 71, a pointer 72, a measuring range adjusting mechanism 8 and a clamping mechanism 9. A fixing frame 2 is welded on the upper side of the base 1. A placing frame 3 is slidably connected to the fixing frame 2. A telescopic frame 4 is rotatably connected to the rear side of the top of the fixing frame 2. A degree meter 5 is connected to the telescopic frame 4. A fixing rod 7 is welded on the left side inside the degree meter 5. A detector 6 is slidably connected between the fixing rod 7 and the degree meter 5. A first compression spring 71 is connected between the detector 6 and the degree meter 5. The first compression spring 71 is wound around the lower side of the fixing rod 7. A pointer 72 is connected to the upper side of the front part of the detector 6. The pointer 72 is slidably connected to the degree meter 5. A measuring range adjusting mechanism 8 is provided between the placing frame 3 and the fixing frame 2. A clamping mechanism 9 is provided inside the placing frame 3.

[0064] Now referring to Figure 1 and Figure 4, the measurement range adjusting mechanism 8 includes a slider 81, a nut block 82, a lead screw 83 and a fixator 84. Two sliders 81 are connected to the front side of the placement frame 3. The slider 81 is slidably connected to the fixing frame 2. A fixator 84 is welded to the rear side of the right part of the fixing frame 2. A lead screw 83 is rotatably connected to the fixator 84. An anti-slip rubber sleeve is provided on the front side of the lead screw 83. A nut block 82 is threadedly connected to the lead screw 83. The right slider 81 is connected to the nut block 82.

[0065] Now refer to Figure 1 and Figure 5 , the clamping mechanism 9 includes a first support frame 91, a second support frame 92, a second compression spring 93 and a clamp 94. First support frames 91 are welded to the middle of the left and right parts inside the placement frame 3. Second support frames 92 are slidably connected to both of the first support frames 91. Clamps 94 are slidably connected to both of the second support frames 92. The clamp 94 is slidably connected to the placement frame 3. A second compression spring 93 is connected between the left clamp 94 and the left second support frame 92. A second compression spring 93 is connected between the right clamp 94 and the right second support frame 92.

[0066] When people need to detect the surface flatness of a copper clad laminate, they can use this copper clad laminate surface flatness detection device. In the initial state, the detector 6 is in contact with the placement frame 3. First, people manually move the second support frame 92 according to the size of the copper clad laminate, so that the second support frame 92 drives the clamp 94 to move through the second compression spring 93. When the clamp 94 moves to a suitable position, people stop moving the second support frame 92. Then people manually move the detector 6 upward, so that the pointer 72 moves upward, causing the first compression spring 71 to be stretched. Then people manually move the clamp 94 outward, so that the second compression spring 93 is compressed. When the clamp 94 moves to a suitable position, people place the copper clad laminate in the placement frame 3, between the two clamps 94. After placing, people release the clamp 94 and the detector 6, so that the first compression spring 71 drives the detector 6 to move downward, causing the pointer 72 to move downward. Subsequently, the detector 6 contacts the copper clad laminate, and the first compression spring 71 is still in a stretched state. At the same time, the second compression spring 93 resets and drives the clamp 94 to move inward to contact the copper clad laminate, thus achieving the clamping effect. Subsequently, when people need to detect the surface of the copper clad laminate in an arc shape, people can manually move the protractor 5, so that the telescopic frame 4 adapts to stretch or shorten, causing the detector 6 to move. When the detector 6 moves to a suitable position, people manually rotate the telescopic frame 4, so that the protractor 5 and the detector 6 rotate. When the detector 6 does not move up and down during the rotation process, it means that the surface of the copper clad laminate is flat. When the detector 6 contacts the raised part of the copper clad laminate surface, the detector 6 adapts to move upward, causing the pointer 72 to move upward, and the first compression spring 71 is stretched. People can know the raised height according to the degree pointed by the pointer 72 on the protractor 5. Subsequently, when the detector 6 moves to the flat copper clad laminate surface, the first compression spring 71 drives the detector 6 to move downward, causing the pointer 72 to move downward. When the detector 6 contacts the groove part of the copper clad laminate surface, the first compression spring 71 drives the detector 6 to move downward, causing the pointer 72 to move downward. People can know the groove height according to the degree pointed by the pointer 72 on the protractor 5. Subsequently, when the detector 6 moves to the flat copper clad laminate surface, the detector 6 and the pointer 72 move upward, causing the first compression spring 71 to continue to be stretched. When the arc-shaped detection is completed, people can reverse-rotate the telescopic frame 4 to a suitable position, so that the protractor 5 and the detector 6 rotate in the reverse direction. When people need to detect the surface of the copper clad laminate vertically, after moving the detector 6 to a suitable position according to the above steps, people can manually rotate the lead screw 83, so that the nut block 82 moves backward, causing the slider 81 and the placement frame 3 to move backward, and the copper clad laminate to move backward. Subsequently, the detector 6 detects the surface of the copper clad laminate according to the above steps. When the detection is completed, people manually reverse-rotate the lead screw 83, so that the nut block 82 moves forward, causing the slider 81 and the placement frame 3 to move forward, and the copper clad laminate to move forward.When the placement frame 3 moves to a suitable position, people stop rotating the lead screw 83. Then, people manually move the clamp 94 outward to a suitable position, causing the second compression spring 93 to be compressed. At the same time, people manually move the detector 6 upward, causing the pointer 72 to move upward and the first compression spring 71 to be stretched. Subsequently, people take out the detected copper clad laminate. After taking it out, people release the clamp 94 and the detector 6, so that the second compression spring 93 resets and drives the clamp 94 to move inward and reset, and the first compression spring 71 resets and drives the pointer 72 and the detector 6 to move downward and reset.

[0067] Embodiment 2

[0068] Based on Embodiment 1, now refer to Figure 1 、 Figure 2 and Figure 6 There is also an outward convex marking mechanism 10, which includes a pushing block 101, a first fixed shaft 102, a rotating frame 103, a first marker 104, a second fixed shaft 105 and a third compression spring 106. A pushing block 101 is connected to the upper left side of the detector 6. A first fixed shaft 102 is welded to the left side inside the degree meter 5. A rotating frame 103 is rotatably connected to the first fixed shaft 102. After the pushing block 101 moves, it contacts the rotating frame 103. A second fixed shaft 105 is connected to the left part of the degree meter 5. A first marker 104 is slidably connected to the second fixed shaft 105. The first marker 104 is slidably connected to the rotating frame 103. A third compression spring 106 is connected between the first marker 104 and the second fixed shaft 105, and the third compression spring 106 is wound around the second fixed shaft 105.

[0069] Now refer to Figure 1 、 Figure 7 and Figure 8 There is also a clamping width adjustment mechanism 11, which includes a third fixed shaft 111, a clamping block 112 and a fourth compression spring 114. Third fixed shafts 111 are welded to the tops of both second support frames 92. Clamping blocks 112 are slidably connected to both third fixed shafts 111. Four card slots 113 are opened on each of the two first support frames 91. There are eight card slots 113 in total. The left clamping block 112 contacts the left card slots 113, and the right clamping block 112 contacts the right card slots 113. A fourth compression spring 114 is connected between the left clamping block 112 and the left second support frame 92, and a fourth compression spring 114 is connected between the right clamping block 112 and the right second support frame 92. The fourth compression spring 114 is wound around the third fixed shaft 111.

[0070] Now refer to Figure 1 、 Figure 2 and Figure 9, it further includes a concave marking mechanism 12. The concave marking mechanism 12 includes a fourth fixed shaft 121, a fifth compression spring 122, and a second marker 123. The fourth fixed shaft 121 is welded to the lower right side of the dial 5. The second marker 123 is slidably connected to the fourth fixed shaft 121. A fifth compression spring 122 is connected between the second marker 123 and the fourth fixed shaft 121, and the fifth compression spring 122 is wound around the fourth fixed shaft 121.

[0071] Now refer to Figure 1 , Figure 2 and Figure 10 , it further includes a driving mechanism 13. The driving mechanism 13 includes a pressing frame 131, a sixth compression spring 132, a fifth fixed shaft 133, and a squeezing frame 134. The pressing frame 131 is connected to the upper right side of the detector 6. The fifth fixed shaft 133 is welded to the right part of the dial 5. The squeezing frame 134 is slidably connected to the fifth fixed shaft 133. The squeezing frame 134 is slidably connected to the second marker 123. After the pressing frame 131 moves, it contacts the squeezing frame 134. A sixth compression spring 132 is connected between the squeezing frame 134 and the fifth fixed shaft 133, and the sixth compression spring 132 is wound around the fifth fixed shaft 133.

[0072] When the detector 6 contacts the convex part on the copper clad laminate, the detector 6 moves upward to drive the push block 101 to move upward. When the push block 101 moves upward and contacts the rotating frame 103, the rotating frame 103 rotates, so that the first marker 104 moves downward, causing the third compression spring 106 to be compressed. Subsequently, the first marker 104 marks on the copper clad laminate, thus achieving the marking effect. When the detector 6 moves downward to drive the push block 101 to move downward, when the push block 101 moves downward and away from the rotating frame 103, the third compression spring 106 resets to drive the first marker 104 to move upward and reset, causing the rotating frame 103 to rotate in the reverse direction.

[0073] When people need to adaptively move the second support frame 92 according to the size of the copper clad laminate, people can manually move the block 112 upward, so that the fourth compression spring 114 is stretched. When the block 112 moves upward and away from the card slot 113, people can adaptively move the second support frame 92, causing the clamp 94 to move. When the clamp 94 moves to the appropriate position, people release the block 112, so that the fourth compression spring 114 resets to drive the block 112 to move downward into the card slot 113, thus achieving the adjustment effect and facilitating the clamping of copper clad laminates of different sizes.

[0074] When the detector 6 detects a grooved part on the surface of the copper clad laminate, people manually move the second marker 123 downward, so that the fifth compression spring 122 is compressed. When the second marker 123 moves downward and contacts the copper clad laminate, the second marker 123 makes a mark on the copper clad laminate. Subsequently, people release the second marker 123, so that the fifth compression spring 122 resets and drives the second marker 123 to move upward and reset.

[0075] The downward movement of the detector 6 drives the downward movement of the downward pressure frame 131. When the downward pressure frame 131 moves downward and contacts the extrusion frame 134, the downward pressure frame 131 drives the extrusion frame 134 to move to the right, so that the sixth compression spring 132 is compressed, causing the second marker 123 to move downward, thus achieving the effect of automatic marking, saving manpower. The upward movement of the detector 6 drives the upward movement of the downward pressure frame 131. When the downward pressure frame 131 moves upward and away from the extrusion frame 134, the sixth compression spring 132 resets and drives the extrusion frame 134 to move to the left, causing the second marker 123 to move upward.
