Description

Technical Field

[0001] The invention belongs to the technical field of copper clad plate processing, in particular to a copper clad plate oxide layer processing device for circuit board processing. Background Art

In order to ensure that the toner on the thermal transfer paper can be firmly printed on the copper clad laminate when transferring the circuit board, the oxide layer on the surface of the copper clad laminate needs to be polished.

[0003] A patent with publication number CN112894585B discloses an oxide film processing device for copper clad laminates used in integrated circuit boards. The polishing unit and the decontamination and wetting unit are driven down by a lifting unit, so that the wetting head wipes and wets the copper clad laminate, and the polishing head removes the oxide film from the copper clad laminate. After continuing to descend, the lifting unit drives the trigger unit to trigger the copper clad laminate to flip over, thereby realizing the removal of the oxide film on the upper and lower ends of the copper clad laminate.

[0004] In the above-mentioned prior art, when the oxide layers on both sides are polished, the copper clad laminate needs to be fixed before polishing to prevent the copper clad laminate from moving during polishing, and at the same time to facilitate the polishing head to apply force to the surface of the copper clad laminate during polishing. When polishing the copper clad laminate, it is necessary to ensure that the upper end surface of the copper clad laminate is not blocked to avoid polishing dead corners.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1 like Figure 1-Figure 4 As shown, a copper-clad laminate oxide layer processing device for circuit board processing described in an embodiment of the present invention includes a support plate 1, first rectangular plates 13 are rotatably arranged on both sides of the upper end of the support plate 1, and clamping components are respectively arranged on opposite sides of the two first rectangular plates 13, and the clamping components include two U-shaped blocks 132 that are slidably arranged at the upper and lower ends of one side of the first rectangular plate 13, and third rectangular plates 133 are fixedly connected to one side of the two U-shaped blocks 132, and fourth rectangular plates 134 are slidably arranged on the opposite sides of the two third rectangular plates 133, and second rectangular bars 1343 are respectively arranged on one side of the fourth rectangular plate 134, and the fourth rectangular plates 134 are respectively located on the upper and lower sides of the copper-clad laminate, and the second rectangular bar 1343 is located on the side wall of the copper-clad laminate. A grinding component is provided above the support plate 1, and the grinding component includes a grinding head 2, and a second motor 211 is fixedly connected to the upper end of the grinding head 2 through a rotating shaft 21, and the second motor 211 can move on the upper end of the support plate 1 through a sliding component.

[0023] Specifically, the oxide layer of the copper clad board of the circuit board may affect the conductivity of the circuit board, because the oxide layer may cause poor current transmission or short circuit. These oxide layers can be removed by polishing to ensure that the copper layer on the circuit board remains clean, thereby improving the conductivity of the circuit board. In addition, polishing can also remove dirt and oxides on the surface of the copper clad board to prepare for subsequent surface treatments, such as gold plating, tin spraying, etc., to improve the corrosion resistance and weldability of the circuit board. When polishing the copper clad board, double-sided polishing is required. Generally, one side is polished first, and then the copper clad board is turned over and the other side is polished. The copper clad board needs to be fixed during the polishing process. , to prevent the copper clad plate from moving during the grinding process. When flipping the copper clad plate, it is necessary to remove the copper clad plate, flip it over, and then fix it again. Due to the thin thickness of the copper clad plate, it is necessary to clamp the edges of both ends of the copper clad plate when flipping it. The clamping plate will cover a part of the copper clad plate when clamping. When grinding, the upper end surface of the copper clad plate is completely exposed to the outside when necessary, so as to perform all-round grinding. The flipping steps are relatively cumbersome. When using the present device, the two fourth rectangular plates 134 at the lower end are driven to slide out to the side of the third rectangular plate 133, and then the copper clad plate is placed on the upper end of the fourth rectangular plate 134, and then the fourth rectangular plate 134 is driven to the side close to the copper clad plate, and the second ... The strip 1343 approaches and clings to the side wall of the copper clad laminate, thereby fixing the copper clad laminate, and then the second motor 211 is started to drive the grinding head 2 to rotate through the rotating shaft 21 to grind the upper end surface of the copper clad laminate. After the grinding is completed, the two fourth rectangular plates 134 at the upper end are driven to slide toward the side close to the copper clad laminate, and then the two U-shaped blocks 132 are driven to slide close to each other on one side of the first rectangular plate 13. The U-shaped block 132 drives the fourth rectangular plates 134 to approach each other through the third rectangular plate 133 to clamp the edge of the copper clad laminate, and then the first rectangular plate 13 is driven to rotate 180 degrees, driving the copper clad laminate to rotate 180 degrees, so that the unpolished side of the copper clad laminate is located at the upper end, and then the position is driven. The fourth rectangular plates 134 on both sides of the upper end of the copper clad laminate slide into the U-shaped block 132 to completely expose the upper end of the copper clad laminate, and then polishing is performed. The oxide layer of the copper clad laminate can be automatically polished and automatically flipped. The copper clad laminate can be clamped during the flipping process to prevent it from falling off. When the copper clad laminate needs to be polished, the two fourth rectangular plates 134 located at the upper end can be slid to the side away from the copper clad laminate, so that the upper end of the copper clad laminate can be completely exposed for all-round polishing. This solves the problem that when polishing the copper clad laminate and flipping the copper clad laminate, the copper clad laminate needs to be removed, flipped, and then re-fixed for polishing again. The process is relatively cumbersome and the polishing efficiency is low.

[0024] like Figure 3 As shown, a rectangular groove 1341 is respectively provided on one side of the two fourth rectangular plates 134 opposite to each other and close to the inner side of the U-shaped block 132 , and the inner side of the rectangular groove 1341 is fixedly connected to the second rectangular bar 1343 via a first spring 1342 .

[0025] Specifically, after the copper clad laminate is placed on the upper ends of the two fourth rectangular plates 134, the fourth rectangular plates 134 on both sides simultaneously approach one side of the film-clad laminate, so that both sides of the film-clad laminate contact the second rectangular strips 1343, and the second rectangular strips 1343 are tightly attached to the side of the film-clad laminate to clamp and fix the copper clad laminate. When the fourth rectangular plates 134 approach each other, the second rectangular strips 1343 slide into the rectangular groove 1341 and squeeze the first spring 1342.

[0026] like Figure 2 As shown, the first rectangular bar 12 is fixedly connected to both sides of the upper end of the support plate 1, and the second cylinder 143 is rotatably connected to the middle of the first rectangular bar 12. The opposite ends of the two second cylinders 143 are respectively fixed to the first rectangular plate 13, and the end of the second cylinder 143 away from the first rectangular plate 13 is fixed to the output end of the first motor 1432 through the second cylindrical rod 1431. The upper end of the first rectangular bar 12 is fixedly connected to the fourth rectangular bar 147 through the fifth rectangular bar 148, and the lower end of the fourth rectangular bar 147 is fixed to the support plate 1, the second cylindrical rod 1431 runs through the middle of the fourth rectangular bar 147, and the first motor 1432 is fixed to the fourth rectangular bar 147 through the motor seat.

[0027] Specifically, when the copper clad laminate needs to be flipped, the fourth rectangular plate 134 is driven to clamp the edge of the copper clad laminate, and the first motor 1432 is started to drive the second cylinder 143 to rotate through the second cylindrical rod 1431. The second cylinder 143 drives the first rectangular plate 13 to rotate. The first rectangular plate 13 drives the copper clad laminate clamped in the middle of the fourth rectangular plate 134 to flip, so that both sides of the copper clad laminate can be polished.

[0028] like Figure 2 As shown, a first rectangular hole 11 is provided in the middle of the support plate 1, and the four corners of the lower end of the support plate 1 are fixedly connected to the bottom plate 151 through the second fixing block 15, and one end of the second cylinder 143 is respectively fixedly connected to the first sprocket 14, and the first sprocket 14 is respectively located between the first rectangular plate 13 and the first rectangular bar 12, and the first sprocket 14 is respectively driven by the chain 141 and the second sprocket 142, and the middle part of one side of the second cylinder 143 is respectively rotatably connected to the waist-shaped bar 144, and the lower end of the waist-shaped bar 144 A cylindrical block 145 is fixedly connected to one side, and the cylindrical block 145 can be slidably fixed inside one side of the first rectangular hole 11. The second sprocket 142 is rotatably connected to the waist-shaped bar 144 through a pin shaft. The second sprocket 142 is fixedly connected to the side away from the waist-shaped bar 144 with a first cylindrical rod 1421. The two first cylindrical rods 1421 are connected by a first cylinder 1422, and the first cylinder 1422 is fixedly connected to the bottom plate 151 through a first fixing block 1423.

[0029] Specifically, when the copper clad plate needs to be controlled to flip, the first motor 1432 on one side is started to drive the second cylinder 143 to rotate through the second cylindrical rod 1431, the second cylinder 143 drives the first sprocket 14 to rotate, the first sprocket 14 drives the second sprocket 142 to rotate through the chain 141, the second sprocket 142 drives the first cylindrical rod 1421 on one side to rotate, the first cylindrical rod 1421 drives the first cylindrical rod 1421 on the other side to rotate through the first cylinder 1422, and the first cylindrical rod 1421 on the other side is driven by the second sprocket 142 and the chain 141. The first sprocket 14 on the side away from the first motor 1432 is driven to rotate, and the first sprocket 14 on the side away from the first motor 1432 drives the first rectangular plate 13 to rotate through the second cylinder 143. By starting the first motor 1432 on one side, the clamping assemblies on both sides can be driven to rotate at the same time, thereby ensuring the synchronization of the clamping assemblies on both sides and preventing the deformation of the copper clad laminate due to the asynchronization of the clamping assemblies during the flipping process. Since a number of circuits are arranged inside the copper clad laminate, the internal circuits may be squeezed when the copper clad laminate is deformed, thereby causing damage to the internal circuits of the copper clad laminate.

[0030] like Figure 2 As shown, the two second cylinders 143 can slide simultaneously in the middle of the first rectangular strip 12 , and the second cylindrical rod 1431 can slide inside the two ends of the second cylinder 143 .

[0031] Specifically, by driving the first cylindrical rods 1421 on both sides of the first cylinder 1422 to slide inside the first cylinder 1422 at the same time, the first cylindrical rods 1421 on both sides simultaneously drive the cylindrical blocks 145 to slide out from the side walls of the first rectangular hole 11 through the waist-shaped strips 144, and at the same time drive the second cylinder 143 to slide toward the middle at the same time through the waist-shaped strips 144, which can drive the clamping components on both sides to approach the middle at the same time, and the distance between the clamping components on both sides can be adjusted according to the different sizes of copper clad laminates, so that copper clad laminates of different sizes can be polished.

[0032] like Figure 2-Figure 3 As shown, a second rectangular hole 1331 is respectively provided in the middle of the third rectangular plate 133, the fourth rectangular plate 134 can slide in the second rectangular hole 1331 through the second rectangular block 1344, the second rectangular plate 131 is slidably connected to one side of the first rectangular plate 13, the second rectangular plate 131 is respectively fixed to the U-shaped block 132, the first rectangular plate 131 is respectively fixed to one side of the first rectangular block 1311, the second rectangular block 1344 is respectively fixed to the first rectangular block 1311 through the second spring 1345, the fourth rectangular bar 147 is respectively fixed to one side of the rectangular tube 16, one end of the rectangular tube 16 is respectively slidably connected to the sixth rectangular bar 161, the sixth rectangular bar 161 can slide in the middle of the first rectangular bar 12, and the sixth rectangular bar 161 is rotatably connected to the rotating block 162 near one end of the first rectangular plate 13.

[0033] Specifically, the elastic force of the second spring 1345 pushes the second rectangular block 1344 to drive the fourth rectangular plate 134 to slide to the side away from the U-shaped block 132, which is convenient for placing the copper clad laminate. When the copper clad laminate needs to be polished, the fourth rectangular plate 134 located at the upper end needs to be kept away from the upper end of the copper clad laminate to prevent polishing dead corners. At this time, the sixth rectangular bar 161 is driven to slide from the inside of the rectangular tube 16 to the side close to the first rectangular plate 13 until the sixth rectangular bar 161 slides to the upper end of the second rectangular block 1344, and then the rotating block 162 is driven to rotate so that the rotating block 162 is located on the side of the second rectangular block 1344 away from the first rectangular plate 13, and then the sixth rectangular bar 161 is driven to slide into the inside of the rectangular tube 16, and the second rectangular block 1344 is driven to slide to the side close to the first rectangular plate 13 by the rotating block 162, and at the same time, the second spring 1345 is squeezed, and the second rectangular block 1344 drives the fourth rectangular plate 134 to slide away from both sides of the copper clad laminate, so that the upper end of the copper clad laminate is completely exposed at the upper end for easy polishing.

[0034] like Figure 5 As shown, the sliding assembly includes support columns 3 respectively fixed to the upper ends of the fifth rectangular bar 148, a first slide rail 31 is commonly fixed between the two support columns 3, the lower end of the first slide rail 31 is slidably connected to the second slide 311, the lower end of the second slide 311 is fixed to the second slide rail 32, the lower end of the second slide rail 32 is slidably connected to the third slide 321, one side of the third slide 321 is fixed to the third slide rail 33, the upper end of the second motor 211 is fixed to the first slide 27, and the first slide 27 can slide on one side of the third slide rail 33.

[0035] Specifically, by driving the first slide 27 to slide on one side of the third slide rail 33, the grinding head 2 at the lower end can be driven to move upward, leaving space for flipping the copper clad laminate. By driving the third slide 321 to drive the third slide rail 33 to slide on the lower end of the second slide rail 32, and at the same time driving the second slide 311 to drive the second slide rail 32 to slide on the lower end of the first slide rail 31, the grinding head 2 at the lower end can be driven to move in multiple directions, and the upper end of the copper clad laminate can be polished in all directions.

[0036] Embodiment 2 like Figure 4-Figure 5 As shown, compared with Example 1, another embodiment of the present invention is: a third cylinder 22 is rotatably arranged on the outer side of the rotating shaft 21, and the third cylinder 22 is fixedly connected to the first slide 27 through an L-shaped strip 223, and a second ring 24 is provided at the lower end of the outer side of the third cylinder 22, and an arc block 231 is sealingly and slidably connected to the lower end of the second ring 24, and an arc sponge 23 is fixedly connected to the lower end of the arc block 231, the middle part of the second ring 24 is a hollow structure, and an arc hole 2311 is provided in the middle part of the arc block 231, a water pipe 26 is fixedly connected to one side of the upper end of the second ring 24, and a water tank 261 is fixedly connected to the end of the water pipe 26 away from the second ring 24.

[0037] Specifically, since the grinding head 2 needs to rotate at high speed during grinding, the temperature of the copper clad laminate where it is ground will be high. It is necessary to wipe water on the surface of the copper clad laminate to cool it down before grinding. Friction heat will be generated during the grinding process. If this heat is not dissipated in time, it may cause the temperature of the copper clad laminate to rise, thereby affecting the grinding effect. Applying water can help absorb some of the heat. When using this device, an arc-shaped sponge 23 is provided on the side of the grinding head 2. The water in the water tank 261 is transported to the second ring 24 through the water pipe 26. The second ring 2 4 flows into the arc sponge 23 through the arc block 231, and the arc sponge 23 absorbs water. When the grinding head 2 grinds the copper clad laminate, the arc sponge 23 is close to the surface of the copper clad laminate, and the arc sponge 23 applies water to the surface of the copper clad laminate. When the grinding direction of the grinding head 2 changes, the arc block 231 is driven to slide at the lower end of the second ring 24, so that the arc sponge 23 slides following the moving direction of the grinding head 2, ensuring that the grinding position of the grinding head 2 is coated with water, preventing the copper clad laminate from being deformed or damaged due to overheating during the grinding process.

[0038] like Figure 6 As shown, the upper end of the second ring 24 is fixedly connected to the first ring 221 via the third spring 222 , the first ring 221 is fixedly connected to the outer side of the third cylinder 22 , and the water pipe 26 slides through the first ring 221 .

[0039] Specifically, the elastic force of the third spring 222 drives the second ring 24 to be squeezed downward, and the second ring 24 drives the arc sponge 23 to be squeezed downward through the arc block 231, so that the arc sponge 23 is close to the surface of the copper clad laminate during polishing, so that the arc sponge 23 is always in an extruded state, so that the water in the arc sponge 23 is fully coated on the surface of the copper clad laminate.

[0040] like Figure 6 As shown, a plurality of teeth 232 are fixedly connected to the outer side of the arc block 231, an inertial sensor 25 is fixedly connected to one side of the upper end of the first ring 221, the inertial sensor 25 is connected to the third motor 252 through a wiring harness 251, the third motor 252 is fixedly connected to one side of the second ring 24 through a third fixed block 254, a gear 253 is fixedly connected to the output end of the third motor 252, and the gear 253 is meshed with the plurality of teeth 232.

[0041] Specifically, an inertial sensor 25 is installed on the upper end of the first ring 221, and the movement direction of the grinding head 2 is detected by the inertial sensor 25 to control the rotation direction of the third motor 252. The third motor 252 drives the gear 253 to rotate, and the gear 253 drives the arc block 231 and the arc sponge 23 at the lower end to rotate through the teeth 232, so that the arc sponge 23 always moves in the direction of movement of the grinding head 2.

[0042] Working principle: when grinding the copper-clad laminate, the first cylindrical rods 1421 on both sides of the first cylinder 1422 are driven to slide inside the first cylinder 1422 at the same time, and the first cylindrical rods 1421 on both sides drive the cylindrical blocks 145 to slide out from the inside of the side wall of the first rectangular hole 11 through the waist-shaped strips 144 at the same time, and the second cylinder 143 is driven to slide toward the middle at the same time through the waist-shaped strips 144, which can drive the clamping components on both sides to approach the middle at the same time, and the distance between the clamping components on both sides can be adjusted according to the copper-clad laminates of different sizes, and then the two fourth rectangular plates 134 at the lower end are driven to slide out to the side of the third rectangular plate 133, and then the copper-clad laminate is placed on the fourth rectangular plate 134. At the end, the second rectangular block 1344 is pushed by the elastic force of the second spring 1345 to drive the fourth rectangular plates 134 on both sides to approach one side of the film-coated board at the same time, so that the two sides of the film-coated board contact the second rectangular strip 1343, so that the second rectangular strip 1343 is close to the side of the film-coated board, and the copper-clad board is clamped and fixed. When the fourth rectangular plates 134 are close to each other, the second rectangular strip 1343 slides into the rectangular groove 1341 and squeezes the first spring 1342, and then the first slide 27 is driven to slide on one side of the third slide rail 33 to drive the grinding head 2 at the lower end to move downward, and then the second motor 211 is started to drive the grinding head 2 to rotate through the rotating shaft 21 to grind the upper surface of the copper-clad board; During grinding, an arc-shaped sponge 23 is provided on the side of the grinding head 2, and the water in the water tank 261 is transported to the second circular ring 24 through the water pipe 26, and the water in the second circular ring 24 flows into the arc-shaped sponge 23 through the arc-shaped block 231, and the arc-shaped sponge 23 absorbs water. When the grinding head 2 grinds the copper-clad laminate, the arc-shaped sponge 23 is closely attached to the surface of the copper-clad laminate, and the arc-shaped sponge 23 applies water to the surface of the copper-clad laminate. By installing an inertial sensor 25 on the upper end of the first circular ring 221, the inertial sensor 25 detects the movement direction of the grinding head 2 to control the rotation direction of the third motor 252, and the third motor 252 drives the gear 253 to rotate, and the gear 253 drives the arc-shaped block 231 and the arc-shaped sponge 23 at the lower end to rotate through the teeth 232, so that the arc-shaped sponge 23 always moves in the direction of movement of the grinding head 2; When the copper-clad laminate needs to be flipped, the fourth rectangular plate 134 is driven to clamp the edge of the copper-clad laminate, and the first motor 1432 on one side drives the second cylinder 143 to rotate through the second cylindrical rod 1431, and the second cylinder 143 drives the first sprocket 14 to rotate, and the first sprocket 14 drives the second sprocket 142 to rotate through the chain 141, and the second sprocket 142 drives the first cylindrical rod 1421 on one side to rotate, and the first cylindrical rod 1421 drives the first cylindrical rod 1421 on the other side to rotate through the first cylinder 1422, and the first cylindrical rod 1421 on the other side drives the first sprocket 14 on the side away from the first motor 1432 to rotate through the second sprocket 142 and the chain 141, and the first sprocket 14 on the side away from the first motor 1432 drives the first rectangular plate 13 to rotate through the second cylinder 143 By starting the first motor 1432 on one side, the clamping assemblies on both sides can be driven to rotate simultaneously to ensure the synchronization of the clamping assemblies on both sides, and the sixth rectangular bar 161 is driven to slide from the inside of the rectangular tube 16 to the side close to the first rectangular plate 13, until the sixth rectangular bar 161 slides to the upper end of the second rectangular block 1344, and then the rotating block 162 is driven to rotate so that the rotating block 162 is located on the side of the second rectangular block 1344 away from the first rectangular plate 13, and then the sixth rectangular bar 161 is driven to slide into the inside of the rectangular tube 16, and the second rectangular block 1344 is driven to slide toward the side close to the first rectangular plate 13 by the rotating block 162, and at the same time, the second spring 1345 is squeezed, and the second rectangular block 1344 drives the fourth rectangular plate 134 to slide away from both sides of the copper clad plate, so that the upper end of the copper clad plate is completely exposed at the upper end for easy grinding.
