Description

Technical Field

[0001] This utility model relates to the field of double-sided panel production technology, specifically to a corner rounding mechanism for double-sided panel production. Background Technology

[0002] Double-sided boards are printed circuit boards with copper plating on both sides, including the top and bottom layers. They are the most common and widely used type of circuit board. Both sides of the insulating substrate have conductive patterns, and the electrical connections between the two sides are mainly made through vias or pads. Because traces can be routed on both sides, the difficulty of wiring is greatly reduced, hence their widespread adoption.

[0003] According to patent authorization announcement number CN212600814U, a corner rounding machine for double-sided panel production includes a machine housing. A fixed plate is fixedly connected to the rear side of the top of the machine housing. A top plate is fixedly connected to the top of the fixed plate. An electric telescopic rod is fixedly connected to the top of the top plate. The bottom of the electric telescopic rod passes through the top plate and extends to the bottom of the top plate, where a first clamping plate is movably connected via a connecting bearing. A drive motor is fixedly connected to the top of the machine housing. A second clamping plate is fixedly connected to the output end of the drive motor. A rotating disk is provided on the back of the machine housing. This utility model, by setting a transmission mechanism, allows the grinding wheel body to move inward and outward according to the size of the holes in the double-sided panel, controlling the distance between the grinding wheel bodies, thereby achieving the effect of a corner rounding machine for double-sided panel production and solving the problem that existing corner rounding machines for double-sided panel production cannot adjust the position of the grinding wheels according to the size of the double-sided panel.

[0004] However, in existing technologies, when polishing the rounded edges of double-sided panels, the motor shaft drives the polishing wheel to rotate, and then the rotating polishing wheel polishes the rounded edges of the double-sided panels. However, in order to keep the polishing wheel in close contact with the rounded edges, a manual limiting polishing device is usually required, which affects the polishing effect and efficiency. At the same time, the pushing force during polishing can easily cause the upper part of the double-sided panels to float upwards, thus affecting the polishing effect. Utility Model Content

[0005] The purpose of this invention is to provide a corner rounding mechanism for double-sided panel production, which solves the problems of rounding corners of double-sided panels and limiting the downward pressure of double-sided panels.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corner rounding mechanism for double-sided panel production, comprising a worktable, a first telescopic rod fixedly connected to the upper right side of the worktable, a push plate fixedly connected to the left side of the first telescopic rod, the push plate slidably connected to the upper end of the worktable, a double-sided panel slidably placed on the upper end of the worktable, the first telescopic rod pushing the push plate to press tightly against the right side of the double-sided panel, a corner rounding mechanism provided at the upper end of the worktable, and a limit mechanism provided at the upper end of the worktable.

[0012] Preferably, a fifth telescopic rod is fixedly connected to the upper end of the top block, and a front pressure block and a rear pressure block are fixedly connected to the lower end of the fifth telescopic rod respectively. The fifth telescopic rod presses down on the front pressure block and the rear pressure block to fit tightly against the upper end of the double panel.

[0015] 2. This utility model uses the fifth telescopic rod to press down the front and rear pressure blocks respectively, thereby facilitating the pressing down of the front and rear ends of the left side of the double panel by the front and rear pressure blocks respectively, avoiding the double panel from floating up and down under force during sanding and affecting the sanding process.

The first telescopic rod 2 pushes the push plate 3 to be tightly attached to the right side of the double-sided panel 4. A corner-grinding mechanism 5 is provided at the upper end of the worktable 1, and a limit mechanism 6 is provided at the upper end of the worktable 1.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The rounding mechanism 5 includes an arc-shaped groove 51.

A front arc-shaped plate 52 and a rear arc-shaped plate 53 are slidably connected inside the arc-shaped groove 51. The arrangement of the front arc-shaped plate 52 and the rear arc-shaped plate 53 facilitates the grinding of rounded corners. The arc-shaped groove 51 also facilitates the vertical movement of the front arc-shaped plate 52 and the rear arc-shaped plate 53, preventing them from colliding with the worktable 1 during vertical movement. The front arc-shaped plate 52 and the rear arc-shaped plate 53 are the same size. The upper end of the front arc-shaped plate 52 is fixedly connected to... A second telescopic rod 54 is connected to the upper end of the rear arc plate 53, and a third telescopic rod 55 is fixedly connected to it. The model of the second telescopic rod 54 and the third telescopic rod 55 is XWFTL. The second telescopic rod 54 and the third telescopic rod 55 are reciprocating telescopic rods.

This is existing technology and will not be described in detail in this technical solution. The second telescopic rod 54 and the third telescopic rod 55 are respectively fixedly connected to a support frame 56. The lower end of the support frame 56 is fixedly connected to the upper end of the worktable 1.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4The limiting mechanism 6 includes a fourth telescopic rod 61. The fourth telescopic rod 61 is fixedly connected to the front and rear sides of the upper end of the worktable 1, respectively. The fourth telescopic rod 61 is fixedly connected to a front baffle 62 and a rear baffle 63. The front baffle 62 and rear baffle 63 facilitate the front and rear limiting of the double-panel 4, preventing the double-panel 4 from moving back and forth.

The lower end of the fifth telescopic rod 66 is fixedly connected to the front pressure block 67 and the rear pressure block 68 respectively. The fifth telescopic rod 66 presses down the front pressure block 67 and the rear pressure block 68 to be tightly attached to the upper end of the double panel 4. The front pressure block 67 and the rear pressure block 68 are the same size.

[0026] The specific implementation process of this utility model is as follows: In use, the double-sided panel 4 is placed on the upper end of the workbench 1. Then, the first telescopic rod 2 is activated, and the first telescopic rod 2 drives the push plate 3 to move to the left. The push plate 3 is then positioned to the left by the first telescopic rod 2, thus limiting the right side of the double-sided panel 4. The double-sided panel 4 can also be pushed to the left at any time, thereby limiting the two rounded corners on the left side of the double-sided panel 4 to the left as follows: Figure 1-2 At the position shown, the fourth telescopic rod 61 is activated to limit the front baffle 62 and the rear baffle 63 to the front and rear of the double panel 4. Then, the fifth telescopic rod 66 is activated, and the front pressure block 67 and the rear pressure block 68 press down on the left side of the double panel 4. Then, the second telescopic rod 54 and the third telescopic rod 55 are activated. The reciprocating up and down movement of the second telescopic rod 54 and the third telescopic rod 55 drives the front arc plate 52 and the rear arc plate 53 to reciprocate up and down, thereby polishing the rounded edge on the left side.
