Description

Technical Field

[0001] This utility model relates to the field of copper clad laminate processing technology, and in particular to the clamping and limiting structure of a copper clad laminate edge grinding device. Background Technology

[0002] Copper-clad laminate (CCL) is a sheet 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. It is mainly used in the manufacture of printed circuit boards (PCBs) and is widely used in mobile phones, computers, televisions, and other fields. During the processing and forming of CCLs, they need to be cut to appropriate sizes. In the production process of printed circuit boards, the CCLs need to be cut, and burrs will inevitably remain on the edges after cutting. Therefore, these burrs need to be removed from the edges of the CCLs.

[0003] In response, Chinese utility model patent with publication number CN207942270U proposes an automatic edge grinding device for copper-clad laminates, including a conveying platform with several conveying guide rollers, a feeding device at the head end of the conveying platform, several edge grinding devices mounted on one side of the conveying platform, a rotating device mounted on one side of the conveying platform and located between two adjacent edge grinding devices, and a conveying correction device mounted on one side of the conveying platform and located in front of the edge grinding devices.

[0004] However, the problem with the aforementioned automatic edge grinding equipment is that it lacks a structure to limit and position the copper-clad laminate during the grinding process. This makes it impossible to ensure that the edge of the copper-clad laminate that needs to be ground can be correctly fed into the edge grinding device for grinding, thus affecting the grinding quality. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a clamping and limiting structure for a copper-clad laminate edge grinding device. By setting a clamping and conveying mechanism to cooperate with the edge grinding device, the copper-clad laminate can be positioned and conveyed, thereby improving the grinding accuracy and grinding quality.

[0006] To achieve the above objectives, this utility model proposes a clamping and limiting structure for a copper-clad laminate edge grinding device, including a frame, an edge grinding device disposed on one side of the frame, and a clamping and conveying mechanism for cooperating with the edge grinding device. The clamping and conveying mechanism includes a transverse drive mechanism arranged in the same direction as the edge grinding device, a slide plate disposed on the transverse drive mechanism, and a device fixing plate disposed on the upper side of the slide plate. The device fixing plate has a perforation, and a vertically upward-facing negative pressure suction cup is disposed within the perforation. The slide plate also... A limiting slide rod is provided for cooperating with the negative pressure suction cup. A sliding sleeve is provided on the limiting slide rod and slidably connected thereto. The negative pressure suction cup is fixed on the sliding sleeve and can be translated along the limiting slide rod in the direction of approaching and moving away from the edge grinding device. A return spring is provided on the limiting slide rod for driving the sliding sleeve to translate in the direction away from the edge grinding device. A limiting plate for cooperating with the side of the copper-clad laminate and a transverse driver for driving the limiting plate to translate in the direction of approaching and moving away from the edge grinding device are provided on the side of the negative pressure suction cup away from the edge grinding device.

[0007] Preferably, the upper side of the device fixing plate is provided with a plurality of universal ball bearings for cooperating with the negative pressure suction cup.

[0008] Preferably, the sliding sleeve is equipped with a rotary motor for driving the negative pressure suction cup to rotate.

[0009] Preferably, a lifting driver is provided between the skateboard and the equipment fixing plate for driving the equipment fixing plate to move up and down.

[0010] Preferably, the lateral movement drive mechanism includes a lateral movement slide rail arranged laterally, a lateral movement drive cylinder disposed between the lateral movement slide rails, and a slide plate disposed on the upper side of the lateral movement slide rails and the lateral movement drive cylinder.

[0011] The beneficial effects of the clamping and limiting structure of the copper clad laminate edge grinding device of this utility model are as follows: By setting a clamping and conveying mechanism to cooperate with the edge grinding device, this utility model can realize the positioning and conveying of the copper clad laminate, improve the grinding accuracy and grinding quality, and maintain the copper clad laminate firmly fixed during the grinding process, so as to prevent the copper clad laminate from deviating.

[0022] Example 1:

[0023] See Figures 1-4This utility model discloses a clamping and limiting structure for a copper-clad laminate edge grinding device, comprising a frame 1, an edge grinding device 2 for grinding the edge of a copper-clad laminate being provided on one side of the frame 1, a transverse drive mechanism 3 arranged in the same direction as the edge grinding device 2, a slide plate 4 provided on the transverse drive mechanism 3, and an equipment fixing plate 5 provided on the upper side of the slide plate 4. The equipment fixing plate 5 has a hollow hole 51 at its center, and a vertically upward-facing negative pressure suction cup 6 is provided within the hollow hole 51. The slide plate 4 is also provided with a limiting mechanism for cooperating with the negative pressure suction cup 6. The limiting slide rod 7 has a sliding sleeve 71 slidably connected to it. The negative pressure suction cup 6 is fixedly mounted on the sliding sleeve 71 and can be translated along the limiting slide rod 7 towards and away from the edge grinding device 2. The limiting slide rod 7 has a return spring 72 for driving the sliding sleeve 71 to translate away from the edge grinding device 2. The negative pressure suction cup 6 has a limiting plate 8 for cooperating with the side of the copper-clad laminate and a transverse driver 9 for driving the limiting plate 8 to translate towards and away from the edge grinding device 2 on the side away from the edge grinding device 2. In this embodiment, by setting a clamping and conveying mechanism in conjunction with the edge grinding device 2, the positioning and conveying of the copper-clad laminate can be achieved, improving the grinding accuracy and quality. During use, the preceding conveying components, such as a robotic arm or conveyor belt, or manually, convey the copper-clad laminate to be edge-ground onto the upper side of the equipment fixing plate 5 in this embodiment. The negative pressure suction cup 6 is activated to adsorb the copper-clad laminate. Then, the horizontal driver 9 drives the limiting plate 8 to move horizontally towards the edge grinding device 2. When the limiting plate 8 is in contact with the side edge of the copper-clad laminate, the lower side of the negative pressure suction cup 6 is fixed by the sliding sleeve 71, which can move along... The limiting slide bar 7 slides, so that the horizontal driver 9 can drive the copper-clad board to move horizontally towards the grinding device 2 until it reaches the designated position. The copper-clad board extends into the grinding device 2, and the horizontal drive mechanism 3 drives the copper-clad board to move along the grinding device 2, so as to cooperate with the grinding device 2 for uniform grinding. The limiting plate 8, the horizontal driver 9 and the copper-clad board can play a role in positioning the copper-clad board, so that it can better extend into the grinding device 2, improve the grinding accuracy and grinding quality, and can maintain the copper-clad board firmly fixed during the grinding process, preventing the copper-clad board from deviating.

[0024] See Figure 1 , Figure 3 The upper side of the device fixing plate 5 is provided with several universal ball bearings 10 for cooperating with the negative pressure suction cup 6. The copper-clad laminate is placed on the surface of the universal ball bearings 10. On the one hand, the universal ball bearings 10 can limit the copper-clad laminate, restrict its horizontal position, and keep the copper-clad laminate flat. On the other hand, the universal ball bearings 10 can facilitate the movement of the copper-clad laminate.

[0025] See Figure 1 , Figure 2Based on Embodiment 1, the transverse drive mechanism 3 includes a transverse slide rail 31 arranged laterally and a transverse drive cylinder 32 disposed between the transverse slide rail 31. The slide plate 4 is disposed on the upper side of the transverse slide rail 31 and the transverse drive cylinder 32.

[0026] Example 2:

[0027] See Figure 2 The sliding sleeve 71 is equipped with a rotary motor 11 for driving the negative pressure suction cup 6 to rotate. During the polishing process, after one side of the copper-clad laminate is polished, the horizontal driver 9 can drive the limiting plate 8 to move away from the edge polishing device 2, thereby separating the limiting plate 8 from the copper-clad laminate. Then, the rotary motor 11 can drive the negative pressure suction cup 6 to rotate, thereby rotating the copper-clad laminate and switching the direction of the copper-clad laminate. The horizontal driver 9 then drives the limiting plate 8 to move closer to the edge polishing device 2, repositioning and fixing the copper-clad laminate, and then cooperating with the edge polishing device 2 to perform edge polishing again. Repeating the above process can polish all sides of the copper-clad laminate.

[0028] See Figure 2 A lifting driver 12 is provided between the sliding plate 4 and the equipment fixing plate 5 to drive the equipment fixing plate 5 to move up and down. During the loading process, the lifting driver 12 drives the equipment fixing plate 5 to descend a certain height, causing the negative pressure suction cup 6 to protrude, facilitating contact between the negative pressure suction cup 6 and the copper-clad laminate for easy adsorption. After adsorption is completed, the lifting driver 12 drives the equipment fixing plate 5 back to its original position. The negative pressure suction cup 6 is flush with the equipment fixing plate 5.

[0029] The working process of this utility model:

[0030] In the operation of this utility model, a clamping and limiting structure for a copper-clad laminate (CCL) edge grinding device is used. Pre-conveying components, such as robotic arms or conveyor belts, or manually, transport the CCL to be edged onto the upper side of the device fixing plate 5 in this embodiment. A negative pressure suction cup 6 is activated to adsorb the CCL. Then, a horizontal driver 9 drives a limiting plate 8 to move horizontally towards the edge grinding device 2. When the limiting plate 8 is in contact with the side of the CCL, the lower side of the negative pressure suction cup 6 is fixed by a sliding sleeve 71, which can slide along the limiting sliding rod 7. This allows the horizontal driver 9 to move the CCL together towards the edge grinding device 2 until it reaches the designated position, where the CCL extends into the edge grinding device 2. The horizontal drive mechanism 3 then moves the CCL along the edge grinding device 2, thus cooperating with the edge grinding device 2 for uniform grinding. The limiting plate 8, the horizontal driver 9, and the CCL work together to position the CCL, allowing it to better extend into the edge grinding device 2.
