Description

Technical Field

[0001] The utility model relates to the technical field of copper clad plate processing, in particular to an edge grinding structure for copper clad plate production. Background Art

[0002] Copper clad laminate, referred to as copper clad laminate, is a plate-like material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin, covering one or both sides with copper foil and hot pressing. It mainly serves the functions of interconnection, insulation and support for printed circuit boards.

[0003] According to a grinding device for producing and processing copper clad laminates for printed circuit boards disclosed in Chinese patent announcement No. CN220561108U, the patent drives the grinding roller to adjust the position by sliding the connecting rod, thereby realizing convenient control operation of grinding copper clad laminates of different sizes, and at the same time allows the copper clad laminate to fit with the positioning plate, thereby improving the positioning effect of the copper clad laminate, which is conducive to convenient grinding of the copper clad laminate. However, the patent still has certain shortcomings in the actual operation process. Since in the actual grinding process, the copper clad laminate is only fitted with the positioning plate, the positioning plate can only limit the horizontal direction of the copper clad laminate to a certain extent, but cannot limit the longitudinal direction of the copper clad laminate. In the grinding process, the copper clad laminate is easily displaced due to the high-speed rotation of the grinding roller, which affects the quality of the copper clad laminate grinding process. In this regard, the present application provides an edge grinding structure for copper clad laminate production to solve the above problems. Utility Model Content

[0023] 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] In this embodiment, the positioning assembly 600 is a structure used to press and limit the copper clad laminate body 5 .

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the positioning assembly 600 includes a second electric push rod 601 fixed to the bottom of the edge grinding table 1, a bonding plate 602 fixedly installed on the output end of the second electric push rod 601, a connecting plate 603 fixed to the top of the bonding plate 602, a top plate 604 fixed to the top of the connecting plate 603, two linear slides 605 fixed to the top of the top plate 604, a limiting rod 606 slidably connected to the inner side of the linear slide 605, a bolt 607 threadedly connected to the outer side of the linear slide 605, a pressing plate 608 fixed between the bottom ends of the two limiting rods 606, an anti-slip pad 609 bonded to the bottom of the pressing plate 608, a center rod 610 fixed to the top of the pressing plate 608, a holding plate 611 fixed to the top of the center rod 610, and a positioning plate 612 fixed to the top of the limiting rod 606.

[0027] It should be noted that a movable hole is provided on the top of the edge grinding table 1 for the second electric push rod 601 to pass through, so that the second electric push rod 601 can work normally. The bonding plate 602 is located on the back side of the placement plate 4, so that the bonding plate 602 can play a role in abutting and limiting the back side of the copper-clad board body 5. The bottom end of the limiting rod 606 passes through the corresponding linear slide 605 and the top plate 604 in sequence, so that the limiting rod 606 can slide stably.

[0028] In addition, the two limiting rods 606 are distributed symmetrically on the left and right, and the opposite sides of the two limiting rods 606 are flat. The end of the bolt 607 can abut against the flat side of the outer side of the corresponding limiting rod 606, so that the bolt 607 can abut and limit the corresponding limiting rod 606, wherein the other end of the bolt 607 is fixedly installed with a round handle that can be directly rotated by hand.

[0029] At the same time, the top of the center rod 610 passes through the bottom of the top plate 604, and the bottom of the anti-skid pad 609 can fit with the top of the copper clad board body 5. The center rod 610 can be driven to move up and down through the holding plate 611, so that the anti-skid pad 609 can be used to press and limit the copper clad board body 5.

[0030] In this embodiment, the adjusting grinding mechanism 300 is a structure for performing grinding processing and adjusting the grinding height.

[0031] like Figure 1 and Figure 2 As shown, the adjustment and grinding mechanism 300 includes a fixed box 301 fixed between the tops of the two columns 2, a first driving mechanism 302 fixedly installed on the left side of the fixed box 301, a bidirectional screw rod 303 rotatably connected to the inner side of the fixed box 301 through a bearing, two moving blocks 304 threadedly connected to the outer side of the bidirectional screw rod 303, a fixed plate 305 fixed to the bottom of the moving block 304, a first electric push rod 306 fixedly installed at the bottom of the fixed plate 305, and a grinding device 307 fixedly installed on the output shaft of the first electric push rod 306.

[0032] It should be noted that a moving hole for the two moving blocks 304 to slide is opened at the bottom of the fixed box 301, and a straight rod is fixedly connected to the inner side of the moving hole. The right end of the straight rod passes through the two moving blocks 304 in sequence, so that the moving blocks 304 can be moved by the bidirectional screw rod 303 under the restriction of the straight rod.

[0033] In addition, the output shaft of the first drive mechanism 302 passes through the left side of the fixed box 301 and is fixedly connected to the left end of the bidirectional screw rod 303, so that the first drive mechanism 302 can drive the bidirectional screw rod 303 to rotate. The first drive mechanism 302 can be a servo motor, and the bidirectional screw rod 303 is a screw rod structure with two threads on the surface, and the thread directions of the two threads are opposite. The two moving blocks 304 are distributed symmetrically on the left and right, so that the bidirectional screw rod 303 can drive the two moving blocks 304 to move closer to or away from each other when rotating.

[0034] At the same time, the grinding device 307 includes a grinding box, the inner side of the grinding box is rotatably connected to a transmission rod through a bearing, an edge grinding roller is fixedly installed on the outer side of the transmission rod, and a second driving mechanism is fixedly installed on the back of the grinding box. The second driving mechanism can be a small servo motor. Two square blocks are fixedly connected to the top of the grinding box, and a square plate is fixedly connected between the tops of the two corresponding square blocks. The top of the square plate is fixedly connected to the output shaft of the corresponding first electric push rod 306. The top and bottom of the grinding box are both open. The outer side of the edge grinding roller is located on the outer side of the grinding box. The output shaft of the second driving mechanism passes through the back of the corresponding grinding box and is fixedly connected to one end of the back side of the corresponding transmission rod. The edge grinding roller is a cylindrical structure with hard bristles on the surface. Specifically, the edge grinding roller is a cylindrical structure with steel wire bristles on the surface. The rotating steel wire brush can effectively grind the burrs on the edges and corners, so that the grinding device 307 can drive the transmission rod to rotate through the second driving mechanism, and let the edge grinding roller rotate, thereby effectively grinding the burrs on the edges and corners of the copper clad laminate body 5.

[0035] The working principle of the above embodiment is:

[0036] When performing edge grinding, the copper clad laminate body 5 is placed on the placement plate 4, and one side of the copper clad laminate body 5 is brought into contact with the front side of the bonding plate 602. The first electric push rod 306 is started to drive the two grinding devices 307 to adjust to the two sides of the copper clad laminate body 5 respectively. The first driving mechanism 302 is started to drive the bidirectional screw rod 303 to rotate, so that the two moving blocks 304 move closer to or away from each other under the rotation thrust of the outer thread of the bidirectional screw rod 303, so that the two grinding devices 307 are close to each other. Move the copper clad laminate body 5 closer to each other and push it to move so that the two grinding devices 307 can fit on both sides of the copper clad laminate body 5 at the same time, loosen the bolts 607, push the holding plate 611 downward, so that the pressure plate 608 moves to the top of the copper clad laminate body 5, and the copper clad laminate body 5 is pressed and limited by the anti-slip pad 609, tighten the bolts 607, so that the two limiting rods 606 can remain stable under the squeezing and limiting action of the bolts 607, and start the grinding device 307 to grind the corners of the copper clad laminate body 5.

[0037] Compared with the prior art, the edge grinding structure for copper clad laminate production, through the coordinated use of the adjusting and grinding mechanism 300 on the top of the edge grinding table 1 and the positioning assembly 600, can facilitate the edge grinding of the copper clad laminate while keeping the copper clad laminate in a stable posture. By pressing and limiting the top of the copper clad laminate, the copper clad laminate is not prone to displacement during the edge grinding process, thereby improving the convenience of the edge grinding process. At the same time, by providing a longitudinally adjustable grinding device 307, the edge grinding requirements of the upper and lower edges of copper clad laminates of different thicknesses can be met, thereby improving the practicality of the edge grinding structure for copper clad laminate production, and solving the problem that the existing edge grinding device for copper clad laminate production and processing only limits the horizontal direction of the copper clad laminate, which easily causes the copper clad laminate to shift in position during the actual processing process.

[0038] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.

[0039] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
