Technical Field

[0001] The present application relates to the technical field of PCB copper plate processing, and particularly relates to a PCB copper plate edge grinding and material collecting machine. Background Art

[0002] In the existing PCB processing technology, the edge grinding treatment of PCB copper plates is an important link in the production process. At present, there are various PCB copper plate edge grinding machines on the market. Most of these devices use a single edge grinding mechanism to perform unilateral edge grinding on PCB copper plates. However, in the actual operation process, when grinding the four sides of the PCB copper plate, it is necessary to flip or reposition the PCB copper plate four times, which greatly reduces the production efficiency. Secondly, for PCB copper plates of different widths, it is necessary to adjust or replace the edge grinding mechanism, which is cumbersome to operate and costly.

[0003] The above information disclosed in this background art is only used to increase the understanding of the background art of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

The vacuum sponge suction cup is connected to the frame through the two-axis feeding system and is used to drive the vacuum sponge suction cup to linearly move along the Z-axis and circularly move around the Z-axis to realize the commutation operation of the copper plate;

[0010] Four of the edge grinding components are respectively arranged in pairs opposite to each other on the frame. Each of the four edge grinding components includes a connecting plate that can move along the Y-axis, and a plurality of edge grinding wheels are rotatably arranged on the connecting plate for grinding the edges of the plate;

[0011] The material receiving assembly includes a plurality of pillow plates arranged in parallel at the feeding end of the copper plate conveyor line, and the pillow plates can move along the Z axis to receive and collect the copper plates. Leveling assemblies are arranged on both sides of the material receiving assembly on the frame, and the leveling assemblies include a push plate movable along the Y axis to extrude and level the stacked and collected copper plates.

[0012] Preferably, two groups of transmission rollers are arranged relatively upper and lower on the connecting plate, and conveyor belts are sleeved on the two groups of transmission rollers. The upper and lower conveyor belts are connected by a chain transmission unit, and the two ends of the spline roller slide through the corresponding transmission rollers of the lower conveyor belt respectively, so as to be used for synchronous rotation of the conveyor belt and the conveyor belt.

The edge grinding components that can be adjusted on both sides are used to perform bilateral edge grinding operations on copper plates of different specifications at the same time. The vacuum sponge suction cup is then used to fix the copper plate, and the direction is reversed. The edge grinding operation is performed by the next set of edge grinding components. This is more convenient. Since the edge grinding components on both sides are edged and conveyed at the same time, the copper plate can be guided to prevent deviation, so that the copper plate is always located in the middle of the copper plate conveyor line, which is convenient for the material receiving component to collect.

[0024] Reference Figure 2 Two adjacent spline rollers 201 are connected by a chain transmission unit to achieve synchronous rotation of the spline rollers 201. One of the spline rollers 201 is connected to an external power input device. Rollers 8 are provided on both sides of the sliding sleeves of the vacuum sponge suction cup 303 on the spline roller 201. The rollers 8 are flush with the upper surface of the conveyor belt 203 to ensure the stability of the copper plate transportation.

[0025] ReferenceFigure 3 The edging assembly 4 further includes an electric telescopic rod 401 installed on the frame 1 by bolts. The end of the electric telescopic rod 401 is connected to the connecting plate 402 by bolts. Two sets of driving rollers are installed on the upper and lower sides of the connecting plate 402 relatively. Conveyor belts 403 are sleeved on the two sets of driving rollers. The upper and lower conveyor belts 403 are connected by a chain drive unit. The two ends of the spline roller 201 slide through the driving rollers of the corresponding lower conveyor belt 403 respectively, realizing the synchronous rotation of the conveyor belt 203 and the conveyor belt 403, maintaining the stability of copper plate conveying.

The moving block 702 is guided by the guide rods sliding through it, ensuring the smooth movement of the moving block 702. The lower surface of the baffle plate 703 is always slightly lower than the height of the copper plate receiving surface.

[0029] The implementation principle of a PCB copper plate edging and receiving machine in an embodiment of this application is as follows:

[0030] The PCB copper plate enters the working area of the edge grinding and material receiving machine through the conveyor belt 203. After the copper plate enters the first set of edge grinding components 4, through the combination of the electric telescopic rod 401 and the connecting plate 402, the copper plate moves in the Y-axis direction so that the edge grinding wheel 404 can perform edge grinding operations along the edge of the copper plate. The edge grinding wheels 404 are connected by a chain drive unit to ensure synchronous operation and are driven by an external power device to adjust the differential speed between the copper plate and the edge grinding wheels 404, thereby achieving an ideal edge grinding effect. When the copper plate enters the commutation component 3, first, the vacuum sponge suction cup 303 controlled by the two-axis feeding system adsorbs the copper plate, enabling precise positioning of the copper plate in the Z-axis direction and realizing a 90-degree rotation and commutation to adjust the direction of the copper plate to the direction where edge grinding is required next. Then, after the copper plate enters the second set of edge grinding components 4, through the combination of the electric telescopic rod 401 and the connecting plate 402, the copper plate moves in the Y-axis direction so that the edge grinding wheel 404 can perform edge grinding operations along the edge of the copper plate. The edge grinding wheels 404 are connected by a chain drive unit to ensure synchronous operation and are driven by an external power device to adjust the differential speed between the copper plate and the edge grinding wheels 404, thereby achieving an ideal edge grinding effect. After edge grinding is completed, the copper plate enters the material receiving component 5. The scissor lift 501 controls the up and down movement of the pillow plate 502 to ensure that the pillow plate 502 is at an appropriate height to receive and stabilize the copper plate, and the baffle 703 blocks the copper plate to prevent the copper plate from crossing the baffle 703. Finally, the telescopic cylinder 601 is used to drive the push plate 602 to move along the Y-axis to extrude and flatten the copper plate to ensure the flatness of its surface and the overall quality.
