[0026] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0027] like Figure 1-4 As shown: it includes a bracket 100 arranged in the etching machine and a first conveying mechanism 200 arranged on the bracket 100. When the copper clad laminate is being etched, the copper clad laminate is located above the first conveying mechanism 200, and the first conveying mechanism 200 can convey the copper clad laminate. The bracket 100 is also provided with a second conveying mechanism 400 through a buffer component 300. The buffer component can push the second conveying mechanism 400 against the first conveying mechanism 200. The second conveying mechanism 400 is located above the first conveying mechanism 200 and has the same structure as the first conveying mechanism 200. The first conveying mechanism 200 and the second conveying mechanism 400 can clamp and convey the copper clad laminate.

[0028] The first conveying mechanism 200 includes a support frame 201 arranged on the bracket 100. The cross-section of the support frame 201 is a rectangular frame structure. A plurality of rotating rods 202 are rotatably provided on the support frame 201. The plurality of rotating rods 202 are arranged in a linear array on the support frame 201. Both ends of each rotating rod 202 are connected to the support frame 201 through bearings. Each rotating rod 202 can rotate on the support frame 201. Each rotating rod 202 is provided with a plurality of rotating wheels 203. The rotating wheels 203 and the rotating rod 202 are located on the same axis. The rotation of the rotating rod 202 can drive the rotating wheels 203 to rotate. The rotating wheels 203 on every two adjacent rotating rods 202 are staggered with each other; the staggered rotating wheels 203 can prevent the upper surface or the lower surface of the copper clad laminate from being interfered with by the rotating wheels 203, thereby preventing some positions on the copper clad laminate from being unable to contact the etching liquid.

[0029] When etching the copper clad laminate, the copper clad laminate is placed above the multiple rotating wheels 203 of the first conveying mechanism 200. The rotating rod 202 on the first conveying mechanism 200 can drive the rotating wheels 203 to rotate, thereby transporting the copper clad laminate. The buffer assembly can also make the second conveying mechanism 400 contact the first conveying mechanism 200, so that the second conveying mechanism 400 and the multiple rotating wheels 203 on the first conveying mechanism 200 can limit and fix the copper clad laminate from the upper and lower surfaces of the copper clad laminate, thereby preventing the copper clad laminate from being jumped by the high-pressure nozzle during movement.

[0030] like Figure 1 、 3 ,4,

[0031] The plurality of rotating rods 202 on the first conveying mechanism 200 are connected to the transmission mechanism 500. The transmission mechanism 500 can drive the plurality of rotating rods 202 on the first conveying mechanism 200 to rotate simultaneously, so that the first conveying mechanism 200 can indirectly drive the copper clad laminate to move;

[0032] When the first conveying mechanism 200 drives the copper clad laminate to move, the copper clad laminate can also drive the rotating wheel 203 and the rotating rod 202 on the second conveying mechanism 400 to rotate due to the friction force.

[0033] like Figure 1 、 3 As shown,

[0034] The transmission mechanism 500 includes two bearing seats 501 provided on the bracket 100. The two bearing seats 501 are symmetrically arranged on the sides of the bracket 100. A worm 502 is provided between the two bearing seats 501. Both ends of the worm 502 are connected to the bearing seats 501 through bearings, so that the worm 502 can rotate between the two bearing seats 501. One end of the worm 502 is connected to an external driving device, which can drive the worm 502 to rotate between the two bearing seats 501. A worm gear 503 is provided at the end of each rotating rod 202 corresponding to the worm 502. The worm gear 503 is coaxially arranged with the worm 502, and the worm 502 and the multiple worm gears 503 are meshed with each other.

[0035] That is, when the transmission mechanism 500 is working, the worm 502 is driven by the external driving device to rotate between the two bearing seats 501, and the worm 502 can drive multiple worm wheels 503 to rotate synchronously, and the worm wheel 503 can drive multiple rotating wheels 203 on the first transmission mechanism 200 to rotate synchronously through the rotating rod 202.

[0036] like Figure 1 、 2 As shown,

[0037] The buffer assembly includes a plurality of telescopic rods 301 arranged at the top of the vertical bracket 100. The ends of the telescopic rods 301 are connected to the support frame on the second conveying mechanism 400. The telescopic rods 301 can guide and support the support frame on the second conveying mechanism 400. A spring 302 is also provided on the telescopic rod 301. The telescopic rod 301 can provide guidance for the spring 302, thereby preventing the spring 302 from bending during the stretching process. One end of the spring 302 is connected to the bracket 100, and the other end of the spring 302 is connected to the support frame. The spring 302 can always push the second conveying mechanism 400 downward, so that the buffer assembly can push the second conveying mechanism 400 against the first conveying mechanism 200 together, so that the first conveying mechanism 200 and the second conveying mechanism 400 can clamp copper clad laminates of different thicknesses, and then can etch copper clad laminates of different thicknesses.

[0038] like Figure 3 、 4 As shown,

[0039] A rubber ring 204 is also provided on the outer surface of the rotating wheel 203. The rubber ring 204 not only increases the friction between the rotating wheel 203 and the copper clad laminate, thereby making the clamping and transmission of the copper clad laminate by the rotating wheel 203 more stable, but also prevents the outer surface of the copper clad laminate from being damaged during the process of the rotating wheel 203 clamping the copper clad laminate.

[0040] like Figure 4 As shown,

[0041] A storage hole 205 is provided on the rubber ring 204, and the rubber ring 204 is connected to the rotating wheel 203 by a bolt. The end of the bolt is located in the storage hole 205, and the storage hole 205 can provide a space for the end of the bolt. In this embodiment, the bolt is also a countersunk screw, so that the bolt not only facilitates the replacement of the rubber ring 204, but also prevents the bolt from directly contacting the copper clad plate.

[0042] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0043] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
