Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a high-efficiency polishing device for ceramic copper-clad substrates. Background Technology

[0002] Copper clad laminate is a plate-shaped material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin, covering one or both sides with copper foil, and then hot-pressing it. Circuit boards can be made from copper clad laminate. During the production process of copper clad laminate, burrs will be generated on the edges of the copper clad laminate. Therefore, grinding equipment is needed to grind the burrs generated.

[0003] Publication No. CN117381606B discloses a copper-clad laminate polishing device. With the first and second polishing machines in the polishing position, they can polish the two opposite edges of the copper-clad laminate respectively, thus completing the polishing of the two opposite edges. However, this patent still has the following problems in actual use:

[0004] When the aforementioned device polishes both sides of the copper-clad laminate, it does not apply a stabilizing force to the other two sides of the copper-clad laminate. This may cause the copper-clad laminate to move or shift when the polishing belt on the polishing device polishes both sides of the copper-clad laminate, which may result in unsatisfactory polishing of both sides of the copper-clad laminate.

[0005] A high-efficiency polishing device for copper-clad ceramic substrates is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency polishing device for ceramic copper-clad substrates, to solve the problem mentioned in the background art. In the current method, when the first and second polishing machines are in the polishing position, the first and second polishing machines can polish the two opposite edges of the copper-clad substrate respectively, thereby completing the polishing of the two opposite edges of the copper-clad substrate. However, when the above-mentioned device polishes the two sides of the copper-clad substrate, it does not apply a stabilizing force to the other two sides of the copper-clad substrate. This may cause the copper-clad substrate to move and shift when the polishing belt on the polishing device polishes the two sides of the copper-clad substrate, which may lead to the problem of unsatisfactory polishing of the two sides of the copper-clad substrate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency polishing device for ceramic copper-clad substrates, including a worktable, wherein a placement platform is fixedly installed in the middle of the surface of the worktable; the placement platform is used to support the ceramic copper-clad substrate.

[0008] Grinding devices are respectively provided on the surface of the workbench and on both sides of the placement table along the first direction. A moving component is provided on the workbench, which is used to drive the two grinding devices to move closer to each other or further away from each other.

[0009] Positioning components are respectively provided on the surface of the worktable and on both sides of the placement platform along the second direction; the two positioning components are used together to clamp and fix the ceramic copper-clad substrate; the second direction is perpendicular to the first direction.

[0010] Preferably, the positioning component includes a connecting sleeve fixedly connected to the worktable, a connecting plate fixedly connected to the side of the connecting sleeve near the edge of the worktable, a pull rod movably connected through the middle of the connecting plate, and the pull rod also movably connected through the connecting sleeve; a clamping member is connected to the end of the pull rod away from the connecting plate, a return spring is sleeved on the surface of the pull rod, one end of the return spring is fixedly connected to the clamping member, and the other end is fixedly connected to the connecting sleeve.

[0011] Preferably, the clamping member includes a slider fixedly connected to the pull rod, and a clamping plate disposed on the slider at the end away from the pull rod; the slider is slidably connected to the connecting sleeve.

[0012] Preferably, the side of the clamping plate away from the slider is provided with an elastic sheet.

[0013] Preferably, the moving component includes a drive motor fixedly connected to the worktable, and a double-ended lead screw fixedly connected to the output end of the drive motor through one side surface of the worktable. A recess is formed in the middle of the surface of the worktable, and the double-ended lead screw is disposed in the recess and rotatably connected to the recess. Threaded sleeves are respectively fitted on both sides of the double-ended lead screw, and the threaded sleeves are slidably connected to the recess. A connecting block is fixedly connected to the surface of the threaded sleeve, and the connecting block is fixedly connected to the grinding device located on the same side.

[0014] Preferably, a detection element is also provided on the surface of the workbench 1, which is used to detect whether the placement position of the ceramic copper-clad substrate is in place.

[0015] Preferably, the double-ended lead screw is made of carbon steel.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This high-efficiency polishing device for ceramic copper-clad substrates, by setting a positioning component, can position and press the unpolished sides of the copper-clad board, thereby ensuring the stability of the copper-clad board. This ensures that the copper-clad board will not move when the polishing component polishes the sides of the board. The specific details are as follows:

[0017] 1. By setting up a positioning component, when the copper-clad laminate needs to be polished, pulling the lever causes the slider to move. The movement of the slider causes the clamping plate to move, so that the copper-clad laminate can be placed on the placement table after the clamping plate is moved to a certain position. After the copper-clad laminate is placed on the placement table, releasing the lever causes the slider to return to its original position under the action of the return spring. The movement of the slider causes the clamping plate to move, so that the clamping plate can clamp the two sides of the copper-clad laminate, thereby ensuring that the copper-clad laminate will not shift during polishing.

[0018] 2. By setting up a moving component, when polishing the other two sides of the copper-clad laminate, after the positioning component stops positioning the copper-clad laminate, the drive motor is started by a control switch. The output of the drive motor drives the double-ended lead screw to rotate. The rotation of the double-ended lead screw drives the threaded sleeve to move. At the same time, the threaded sleeve is fixedly connected to the connecting block, and the connecting block is fixedly connected to the polishing device. The polishing device is set to fit against the worktable. Through the cooperation between the connecting block and the polishing device, the threaded sleeve can be limited, thereby allowing the threaded sleeve to move... As the double-ended lead screw moves and the two threaded sleeves move to both sides of the lead screw, the grinding device moves to both sides, moving away from the copper-clad laminate. This allows the copper-clad laminate to be repositioned. After the copper-clad laminate is repositioned, the drive motor is restarted, causing the output of the drive motor to reverse the double-ended lead screw. This causes the two threaded sleeves to move to the middle position of the double-ended lead screw, allowing the other two sides of the copper-clad laminate to be ground. This improves the grinding efficiency of the copper-clad laminate to a certain extent. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency polishing device for ceramic copper-clad substrates, comprising: a worktable 1, a placement platform 2 fixedly installed in the middle of the surface of the worktable 1; the placement platform 2 is used to support the ceramic copper-clad substrate; polishing devices 3 are respectively arranged on the surface of the worktable 1 and on both sides of the placement platform 2 along a first direction; a moving component 5 is arranged on the worktable 1, the moving component 5 is used to drive the two polishing devices 3 to move closer or further apart; positioning components 4 are respectively arranged on the surface of the worktable 1 and on both sides of the placement platform 2 along a second direction; the two positioning components 4 are used in cooperation to clamp and fix the ceramic copper-clad substrate; the second direction is perpendicular to the first direction.

[0028] like Figure 1-5 As shown, both the first and second directions are horizontal, and the first direction is... Figure 1 The middle left and right directions, the second direction is Figure 2 In the vertical direction, the positioning component 4 is set to position and squeeze the two sides of the copper-clad laminate that have not been polished, thereby ensuring the stability of the copper-clad laminate. This ensures that the copper-clad laminate will not move when the polishing component polishes the two sides of the copper-clad laminate. The polishing device 3 is existing technology and its working principle is the same as existing technology, so it will not be described in detail here.

[0029] The positioning component 4 includes a connecting sleeve 401 fixedly connected to the worktable 1. A connecting plate 402 is fixedly connected to the side of the connecting sleeve 401 near the edge of the worktable 1. A pull rod 403 is movably connected through the middle of the connecting plate 402. The pull rod 403 is also movably connected through the connecting sleeve 401. A clamping member is connected to the end of the pull rod 403 away from the connecting plate 402. A return spring 404 is sleeved on the surface of the pull rod 403. One end of the return spring 404 is fixedly connected to the clamping member, and the other end is fixedly connected to the connecting sleeve 401.

[0030] The clamping component includes a slider 405 fixedly connected to the pull rod 403, and a clamping plate 406 disposed at the end of the slider 405 away from the pull rod 403; the slider 405 is slidably connected to the connecting sleeve 401. By setting the slider 405 slidably connected to the connecting sleeve 401, the clamping plate 406 can be made stable during movement.

[0031] Preferably, the side of the clamping plate 406 away from the slider 405 is provided with an elastic sheet, which is made of, for example, rubber. The bottom surface of the clamping plate 406 is fitted to the worktable 1.

[0032] like Figure 3 , 5 As shown, when the copper-clad laminate needs to be polished, by pulling the lever 403, the lever 403 can drive the slider 405 to move. The movement of the slider 405 can drive the clamping plate 406 to move. After the clamping plate 406 moves to a certain position, the copper-clad laminate can be placed on the placement stage 2. After the copper-clad laminate is placed on the placement stage 2, by releasing the lever 403, the slider 405 returns to its original position under the action of the return spring 404. The movement of the slider 405 can drive the movement of the clamping plate 406, so that the clamping plate 406 can clamp the two sides of the copper-clad laminate, thereby ensuring that the copper-clad laminate will not shift during polishing.

[0033] Meanwhile, the clamping plate 406 has an elastic sheet made of rubber on one side for clamping the copper-clad laminate. The friction coefficient of rubber is usually large, which makes the friction force on the copper-clad laminate greater. As a result, the friction force of the clamping plate 406 on the copper-clad laminate is greater than the friction force of the polishing device 3 on the copper-clad laminate, so that the copper-clad laminate will not be moved or shifted.

[0034] The moving component 5 includes a drive motor 501 fixedly connected to the worktable 1. The output end of the drive motor 501 passes through one side surface of the worktable 1 and is fixedly connected to a double-ended lead screw 502. A groove 6 is formed in the middle of the surface of the worktable 1. The groove 6 extends along a first direction. The double-ended lead screw 502 is located in the groove 6 and is rotatably connected to the groove 6. Threaded sleeves 503 are threaded on both sides of the double-ended lead screw 502. The threaded sleeves 503 are slidably connected to the groove 6. A connecting block 504 is fixedly connected in the middle of the surface of the threaded sleeve 503. The connecting block 504 is fixedly connected to the grinding device 3 located on the same side.

[0035] like Figure 2 , 4 As shown, by setting the moving component 5, when polishing the other two sides of the copper-clad laminate, after the positioning component 4 stops positioning the copper-clad laminate, the drive motor 501 is started by the control switch, so that the output end of the drive motor 501 drives the double-ended lead screw 502 to rotate. The rotation of the double-ended lead screw 502 can drive the threaded sleeve 503 to move. At the same time, the threaded sleeve 503 is fixedly connected to the connecting block 504, and the connecting block 504 is fixedly connected to the polishing device 3. The polishing device 3 is fitted to the worktable 1. Through the cooperation between the connecting block 504 and the polishing device 3, the threaded sleeve 503 can be limited, thereby making the threaded sleeve 503 move. The threaded sleeve 503 can move on the double-ended lead screw 502. When the two threaded sleeves 503 move to both sides of the double-ended lead screw 502, they will drive the polishing device 3 to move to both sides, thereby moving the polishing device 3 away from the copper-clad laminate. This allows the copper-clad laminate to be repositioned. After the copper-clad laminate is repositioned, the drive motor 501 is restarted, causing the output end of the drive motor 501 to drive the double-ended lead screw 502 to reverse. This causes the two threaded sleeves 503 to move to the middle position of the double-ended lead screw 502, thereby allowing the other two sides of the copper-clad laminate to be polished. This improves the polishing efficiency of the copper-clad laminate to a certain extent.

[0036] Preferably, the double-ended lead screw 502 is made of carbon steel, such as... Figure 4 As shown, the double-ended lead screw 502, made of carbon steel, has high strength and hardness, can withstand large loads, has good machinability, and is relatively low in cost. To prevent the threaded sleeve 503 from becoming immobile due to debris generated during grinding, the surface of the double-ended lead screw 502 can be cleaned after grinding the copper-clad laminate, reducing debris accumulation. Additionally, a suitable lubricant can be applied to both the double-ended lead screw 502 and the threaded sleeve 503. This lubricant has good lubrication performance and stability; regular application of lubricant can form a protective film on the thread surface, reducing friction and wear, and also helping to prevent impurities from adhering, thus preventing the threaded sleeve 503 from becoming immobile on the double-ended lead screw 502 to some extent.

[0037] Furthermore, a detection element is provided on the surface of the workbench 1, which is used to detect whether the ceramic copper-clad substrate 8 is placed in the correct position.

[0038] Specifically, since both sides of the ceramic copper-clad substrate need to be polished simultaneously, and the two polishing devices move synchronously, to ensure polishing quality, the ceramic copper-clad substrate must be placed precisely in the center of the two polishing devices. If the ceramic copper-clad substrate is placed too far to the left or right, it will affect the polishing effect. Therefore, a detection element is installed on the surface of the worktable 1 to detect whether the ceramic copper-clad substrate is positioned correctly. The detection element is, for example, a photoelectric sensor, which includes a transmitter 701 and a receiver 702. Figure 6 As shown, in this embodiment, there are two detection elements. The transmitters 701 of the two detection elements are respectively located on both sides of one of the positioning components 4 along the first direction, and the receivers 702 of the two detection elements are respectively located on both sides of the other positioning component 4 along the first direction. The transmitters 701 and receivers 702 belonging to the same detection element are distributed along the second direction.

[0039] The working principle of a photoelectric sensor is based on the photoelectric effect. Its emitter emits light signals of a specific wavelength, which are reflected or absorbed when they encounter an object. The receiver detects these reflected or transmitted light signals to determine the presence and position of the object. When an object blocks the light beam, the receiver cannot receive the light signal, and the photoelectric sensor outputs a signal. The photoelectric sensor can be connected to a controller, and when the controller receives the signal output by the photoelectric sensor, it will display it on its display panel. Alternatively, it can issue a prompt through an audible and visual alarm to remind the operator that the ceramic copper-clad substrate 8 is not positioned correctly and needs to be adjusted.

[0040] Furthermore, in order to accommodate the polishing of ceramic copper-clad substrates 8 of different sizes, the position of the detection component is set to be adjustable. Specifically, a sliding groove extending in the first direction can be opened on the surface of the worktable 1. The transmitter 701 and receiver 702 of the detection component are slidably connected to the corresponding sliding grooves. A scale is provided on one side of the sliding groove. Before the detection is performed, the transmitter 701 and receiver 702 can be moved to the appropriate position of the sliding groove and fixed according to the size of the ceramic copper-clad substrate 8.

[0041] Alternatively, each transmitter 701 and receiver 702 can be connected to the drive end of an electric actuator, and the electric actuator can be used to move the transmitter 701 and receiver 702 to a suitable position.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
