Description

Technical Field

[0001] The utility model relates to a plate cutting and processing device, belonging to the field of copper clad plate processing. Background Art

[0002] Copper-clad laminate (CCL) is a sheet material made of copper foil on one or both sides and hot-pressed. It is a basic material in the manufacture of printed circuit boards. During the production process, the CCL needs to be cut to obtain the required size. A conveyor device transfers the CCL sheet to the underside of a disc cutter driven by a servo motor. The rotating disc cuts the CCL sheet. After a period of cutting, the blade of the disc is damaged by the reaction force of the CCL sheet, resulting in burrs when the disc cuts the CCL sheet. Therefore, the disc cutter needs to be replaced from time to time. However, the cost of replacing the disc cutter as a whole is high, so it is necessary to design a plate cutting processing device that can achieve partial replacement of the blade. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plate cutting processing device to solve the problems raised in the above background technology. The utility model realizes the partial replacement of the blade and reduces the cost of replacing parts.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a plate cutting processing device, including a carrier plate, a servo motor is installed at the upper position of one side of the carrier plate, the output end of the servo motor passes through the carrier plate and is installed with a transmission shaft, and a cutter disc is installed on the end of the transmission shaft away from the servo motor, and the cutter disc is provided with a ring-shaped blade for cutting copper-clad plate materials, and the inner surface of the blade is annularly fixed with a plurality of protrusions at equal intervals, and the annular side surface of the cutter disc is provided with a plurality of slots matching the protrusions at equal intervals, and the protrusions are inserted in the slots, and the outer surface of the end of the transmission shaft close to the cutter disc is annularly installed with a plurality of support plates at equal intervals, and the support plates are arranged along the radial direction of the transmission shaft, and the end of the support plate away from the transmission shaft is connected and fixed to the protrusions by connecting screws.

[0005] Furthermore, an L-shaped plate is provided between the support plate and the protrusion, one side of the L-shaped plate is in contact with the protrusion, a first through-hole is provided on the side of the support plate facing the protrusion, a second through-hole is provided on one side of the L-shaped plate aligned with the first through-hole, a screw hole is provided on the side of the protrusion facing the L-shaped plate aligned with the second through-hole, and one end of the connecting screw passes through the first through-hole and the second through-hole and is threadedly connected in the screw hole.

[0006] Furthermore, one end of the transmission shaft close to the cutter disc is provided with a pipe sleeve connected and fixed to the transmission shaft, and a plurality of support plates are fixed on the outer surface of the pipe sleeve in a ring-shaped manner and at equal distances.

[0007] Furthermore, a bottom plate is connected and fixed to the lower end of the carrier plate, and two fixing holes are provided on the upper surface of the bottom plate.

[0008] Furthermore, a bearing is sleeved on the transmission shaft, and a support arm is connected and fixed to the outer ring surface of the bearing. The support arm is arranged on the upper side of the carrier plate, and a strip groove arranged along the length direction of the support arm is opened on the upper surface of the support arm. A threaded blind hole is opened in the middle position of the upper surface of the carrier plate, and a positioning bolt for limiting the relative position of the support arm and the carrier plate is inserted in the strip groove, and the lower end of the positioning bolt is threadedly connected to the threaded blind hole.

[0009] Furthermore, a cam is fixedly connected to the middle of the cutter disc facing the transmission shaft, and a connecting disc is fixedly connected to the end of the transmission shaft close to the cutter disc. The connecting disc is fixed to the cam by a plurality of screws.

[0010] Beneficial effects of the utility model:

[0011] 1. The blade is mounted on the cutter disc, and the protrusion inside the blade is inserted into the slot on the cutter disc to connect the blade and the cutter disc. When the cutter disc rotates driven by the servo motor, the protrusion and the slot cooperate with each other to make the blade rotate as well, thereby reducing the load on the connecting screw.

[0012] 2. Use connecting screws to connect the support plate and the bump to fix the relative position of the blade, the cutter head and the drive shaft. When the blade is damaged by the reaction force of the copper-clad laminate, the blade can be replaced by removing the connecting screws without replacing the cutter head, thus realizing partial replacement of the blade and reducing the cost of parts replacement.

[0013] 3. Make the connecting screw pass through the first through-hole and the second through-hole in sequence, and then the support plate and the L-shaped plate work together to make the rod of the connecting screw between the support plate and the L-shaped plate exposed. When it is difficult to separate the connecting screw from the protrusion, use the gap between the support plate and the L-shaped plate to cut off the connecting screw and replace the blade.

[0014] 4. Install the bearing sleeve on the transmission shaft, and use the positioning bolts to connect the carrier plate and the support arm, so that the bearing, support arm and carrier plate can jointly support the bearing, reduce the load on the connection part between the transmission shaft and the output end of the servo motor, and adjust the position of the bearing on the transmission shaft. At this time, the position of the positioning bolt in the strip groove changes, making it easier to adjust the relative position of the transmission shaft and the bearing as needed.
