Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a fine grinding equipment for mirror steel plates. Background Technology

[0002] Copper-clad laminate (CCL) is a composite material made by impregnating reinforcing materials with resin, covering one or both sides with copper foil, and then hot-pressing them. It is used to manufacture printed circuit boards (PCBs), which have become an indispensable component for interconnecting circuits in most electronic products. The main production process includes mixing adhesives, applying adhesive, lamination, shearing, inspection, and packaging. Lamination refers to the sequential stacking of mirror steel plates, copper foil, prepreg, copper foil, and mirror steel plates on a lamination table. Key quality control points include ensuring all materials are neatly stacked to prevent dust contamination of the copper foil and guarantee the product's appearance quality. A common process control method is to control the surface cleanliness and flatness of the mirror steel plate during the lamination process. The cleanliness of the lamination workshop is crucial to prevent contamination of the copper foil surface by dust and other contaminants, thereby controlling the product's appearance quality. The lamination and pressing production lines for copper-clad laminates typically include reflow lines, washing machines, laminating machines, loading and unloading machines, and laminators. The cleaning of mirror-finish steel plates is primarily accomplished by washing machines. These machines use abrasive wheels, brush rollers, water washing, and hot air drying to clean the mirror-finish steel plates, thereby reducing product appearance defects. However, for severely contaminated or partially damaged steel plates, ordinary washing machines are insufficient. These plates are usually manually polished or re-cut for reuse. However, manual polishing can easily reduce the flatness and roughness of the steel plate surface, severely impacting the production quality of the copper-clad laminate.

[0003] According to the new structure retrieval report, announcement number CN220762203U discloses a fine grinding equipment for mirror-finish steel plates, including a device housing. A dual-output shaft motor is fixedly connected to the right side of the device housing, and a movable stud is fixedly connected to the left side of the dual-output shaft motor. A movable block is threadedly connected to the outer side of the movable stud. By setting the movable stud, the grinding plate can rotate left and right, expanding the grinding range of the device. The parallel movement of the movable block ensures the stability during grinding. By setting the movable stud, the grinding plate can move back and forth, further expanding the grinding range of the device. The parallel movement of the movable block ensures the stability during grinding. By setting a cylinder, the height of the steel plate can be adjusted after it is placed on the upper side of the lifting plate, allowing the device to grind steel plates of different thicknesses, improving the practicality of the device, and solving the problem of reduced flatness and roughness of steel plates caused by existing grinding methods.

[0004] The aforementioned technology discloses a fine grinding equipment for mirror steel plates, which achieves surface grinding of mirror steel plates by driving the grinding plate to move, reducing the phenomenon of low flatness and roughness of the plate surface due to severe surface contamination or partial damage. However, it still has the following shortcomings in use: 1. It cannot accurately and automatically control the squeezing and grinding force on the mirror steel plate, and there is an inevitable phenomenon of excessive squeezing pressure causing severe friction or insufficient pressure resulting in ineffective grinding; 2. During grinding, grinding debris and grinding paste applied to the surface of the mirror steel plate inevitably splash outward onto the personnel, and there is a lack of measures for automatic anti-splashing treatment during grinding; In view of this, this application proposes a fine grinding equipment for mirror steel plates to solve the above-mentioned problems.

The vertical guide lifting component is used to drive the cross electric slide rail 302 to move up and down under the control of the PLC controller 301. The pressure-controlled grinding component is used to squeeze and rotate the mirror steel plate for grinding when the cross electric slide rail 302 moves down, and detects the squeezing force and transmits the pressure value to the PLC controller 301. When the pressure value reaches the preset value, the PLC controller 301 controls the vertical guide lifting component to automatically stop the descent, so as to achieve the effect of precise pressure-controlled grinding of the mirror steel plate.

[0039] The counterweight self-enclosing component is movably sleeved on the outside of the vertical guide lifting component and makes contact with the top of the cross electric slide rail 302.

[0040] Specifically, the steel plate clamping and limiting assembly includes a limiting strip 2 fixedly connected to the top of the workbench 1. A clamping plate 201 is provided on the right side of the limiting strip 2. The bottom of the clamping plate 201 movably passes through the rectangular through hole 102 and extends to the bottom of the workbench 1. Two horizontal guide rods 202 are fixedly connected to the left side of the clamping plate 201. The workbench 1 is slidably fitted on the two horizontal guide rods 202. Two horizontal guide grooves are opened on the left inner wall of the rectangular through hole 102, which are respectively slidably fitted on the outer side of the corresponding horizontal guide rods 202, so as to guide the horizontal sliding of the horizontal guide rods 202. An output shaft is fixedly installed at the bottom of the workbench 1 and a first electric telescopic rod 203 is fixedly connected to the bottom left side of the clamping plate 201. The limiting strip 2, clamping plate 201, horizontal guide rods 202 and first electric telescopic rod 203 cooperate to use the limiting strip 2 to block and limit the mirror steel plate to be polished on the left side, and use the first electric telescopic rod 203 to drive the clamping plate 201 to move to the left to clamp the mirror steel plate.

[0041] Furthermore, the vertical guide lifting assembly includes a multi-stage electric telescopic rod 4 fixedly installed on the top of the inverted U-shaped frame 3. The extended end of the multi-stage electric telescopic rod 4 is fixedly connected to the top of the cross electric slide rail 302. Two T-shaped guide rods 401 are fixedly connected to the top of the cross electric slide rail 302. The inverted U-shaped frame 3 is slidably fitted onto the two T-shaped guide rods 401. The top of the inverted U-shaped frame 3 has two first guide holes that are respectively slidably fitted onto the outer side of the corresponding T-shaped guide rods 401, which serve to guide the vertical sliding of the T-shaped guide rods 401. The multi-stage electric telescopic rod 4 is electrically connected to the PLC controller 301. The multi-stage electric telescopic rod 4 and the T-shaped guide rods 401 cooperate to drive the cross electric slide rail 302 to move up and down. The cross electric slide rail 302 drives the two T-shaped guide rods 401 to move up and down to perform vertical guiding work.

[0042] Furthermore, the pressure-controlled grinding assembly includes a pressure sensor 602 fixedly installed at the bottom of the moving end of the cross-shaped electric slide rail 302. A fixing plate 601 is fixedly connected to the bottom of the pressure sensor 602. A drive motor 603 is fixedly installed at the bottom of the fixing plate 601. A mounting plate 604 is fixedly connected to the bottom of the output shaft of the drive motor 603. A grinding disc 605 is fixedly installed at the bottom of the mounting plate 604 by four screws. Four T-shaped guide shafts 6 are fixedly connected in a rectangular shape at the bottom of the moving end of the cross-shaped electric slide rail 302. The 601 is slidably mounted on four T-shaped guide shafts 6. The top of the fixed plate 601 has four rectangular vertical guide holes that slide onto the outer sides of the corresponding T-shaped guide shafts 6, providing vertical sliding guidance for the fixed plate 601. The pressure sensor 602 is electrically connected to the PLC controller 301. The pressure sensor 602, drive motor 603, fixed plate 601, T-shaped guide shafts 6, mounting plate 604, and grinding disc 605 work together. The drive motor 603 drives the grinding disc 605 to rotate, in a cross-shaped electric... When the slide rail 302 moves downward, it drives the pressure sensor 602 downward. The pressure sensor 602, through the fixing plate 601, drive motor 603, and mounting plate 604, drives the grinding disc 605 downward. After the grinding disc 605 presses down on the top of the mirror steel plate, it is blocked and restricted by it. The pressure sensor 602 detects the squeezing force applied by the cross electric slide rail 302 when it moves downward. Utilizing the sequential transmission of force, the detected force is the clamping force between the grinding disc 605 and the mirror steel plate. The pressure sensor 602 transmits the monitored pressure value to the PLC. When the preset pressure value is reached, the PLC controller 301 controls the multi-stage electric telescopic rod 4 to close, achieving precise pressure control grinding of the mirror steel plate. This avoids excessive pressure causing severe friction or insufficient pressure preventing effective grinding. The precise pressure control grinding method facilitates better fine grinding work. In addition, the cross electric slide rail 302 can also drive the grinding disc 605 to move left and right or back and forth to change the grinding position through the T-shaped guide shaft 6, the fixing plate 601, the drive motor 603, and the mounting plate 604.

[0043] Furthermore, the counterweight self-closing assembly includes a transparent shield 5 slidably fitted onto the outside of the two T-shaped guide rods 401. The top of the transparent shield 5 has two second guide holes that slide onto the corresponding outer sides of the T-shaped guide rods 401, providing vertical sliding guidance for the transparent shield 5. A rubber ring 502 is adhesively fixed to the bottom of the transparent shield 5. Counterweight blocks 501 are fixedly connected to the inner walls of both sides of the transparent shield 5. A movable through-hole is provided at the top of the transparent shield 5, and the extended end of the multi-stage electric telescopic rod 4 is located within the movable through-hole. It does not contact the inner wall of the movable perforation; the transparent guard 5, rubber ring 502 and counterweight 501 are set together. When the cross electric slide rail 302 moves down, it reduces the lifting support force on the transparent guard 5. At this time, under its own weight, the two counterweights 501 move down and drive the transparent guard 5 to move down. The transparent guard 5 drives the rubber ring 502 to contact the worktable 1 downward. The transparent guard 5 is used to surround and shield the low grinding position, avoiding the phenomenon of grinding debris and grinding paste applied to the mirror steel plate splashing out onto the personnel.

[0044] The usage method of this embodiment is as follows: When using the mirror steel plate fine grinding equipment, place the mirror steel plate to be ground on top of the anti-slip rubber pad 101 and abut against the right side of the limiting strip 2. Then, start the first electric telescopic rod 203 in reverse to drive the clamping plate 201 to move to the left. The clamping plate 201 drives the two horizontal guide rods 202 to slide to the left in the corresponding horizontal guide grooves. At the same time, the clamping plate 201 clamps the mirror steel plate to the left. The pressure value for controlling the closing of the multi-stage electric telescopic rod 4 is preset using the PLC controller 301. Start the drive motor 603 and start the multi-stage electric telescopic rod 4 in the forward direction. The drive motor 603 drives the grinding disc 605 to rotate. When the multi-stage electric telescopic rod 4 starts in the forward direction, it drives the cross electric slide rail 302 to move downward. The cross electric slide rail 302 drives the two T-shaped guide rods 401 to move downward for vertical guidance. When the cross electric slide rail 302 moves downward, it also drives the pressure sensor 602 to move downward. The pressure sensor 602 passes through the fixing plate 601, the drive motor 603 and the mounting plate 6 in sequence. 04 drives the grinding disc 605 to move downwards. After the grinding disc 605 presses down on the top of the mirror steel plate, it is blocked and restricted by the plate. The pressure sensor 602 detects the squeezing force applied by the cross electric slide rail 302 when it moves downwards. By transmitting the force sequentially, the detected force is the clamping force between the grinding disc 605 and the mirror steel plate. The pressure sensor 602 transmits the monitored pressure value to the PLC controller 301. When the preset pressure value is reached, the PLC controller 301 controls the multi-stage electric telescopic rod 4 to close. At this time, the rotating grinding disc 605 performs grinding work on the surface of the mirror steel plate, achieving a precise pressure-controlled grinding effect on the mirror steel plate. This avoids the effect of excessive pressure causing severe friction or insufficient pressure resulting in ineffective grinding. The precise pressure-controlled grinding method facilitates better fine grinding work and improves the grinding effect. In addition, the cross electric slide rail 302 can also drive the grinding disc 605 to move left and right or back and forth by sequentially driving the T-shaped guide shaft 6, the fixing plate 601, the drive motor 603, and the mounting plate 604 to change the grinding position.

[0045] When the cross-shaped electric slide rail 302 moves downward, it reduces the lifting support force on the transparent guard 5. At this time, under its own weight, the two counterweights 501 move downward, driving the transparent guard 5 downward. The transparent guard 5 drives the rubber ring 502 downward to contact the worktable 1. The transparent guard 5 surrounds and shields the low grinding position, preventing grinding debris and grinding paste applied to the mirror steel plate from splashing onto the personnel. This improves external cleanliness during use and reduces soiling of personnel's clothes, making it more convenient for personnel. Use: After use, the multi-stage electric telescopic rod 4 is reversed to drive the cross electric slide rail 302 to move upward and reset. The cross electric slide rail 302 sequentially drives the grinding disc 605 to move upward and reset through the pressure sensor 602, the fixing plate 601, the drive motor 603 and the mounting plate 604. At the same time, the cross electric slide rail 302 lifts the transparent cover 5 upward to release the surrounding cover. Then, the first electric telescopic rod 203 can be activated in the forward direction to drive the clamping plate 201 to move to the right to release the clamping state, and the mirror steel plate can be removed for replacement.

[0046] The PLC controller 301 is a numerical control programmable controller. The PLC controller 301, pressure sensor 602 and multi-stage electric telescopic rod 4 in this utility model are well known to those skilled in the art and belong to conventional means or common knowledge. Those skilled in the art can arbitrarily select and match them according to their needs or convenience. In addition, the PLC controller 301 receives the pressure value transmitted by the pressure sensor 602 and controls the multi-stage electric telescopic rod 4 to close when the preset value is reached. This is a basic programming parameter setting control method well known to those skilled in the art. All of these are conventional means or common knowledge and will not be described in detail here.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
