[0020] (III) Beneficial effects

[0021] The two-axis full linear PCB drilling machine provided by the present invention has the following beneficial effects:

[0022] 1. Through the mobile mechanism and drilling mechanism, the tool magazine assembly in the mobile mechanism can store various drilling tools and detect the replaced drilling tools. When the drilling tool is seriously worn, the staff will be prompted to replace it. Before each drilling, the manipulator in the drilling mechanism will select the drilling tool from the tool magazine assembly and place it in the installation area on one side of the magazine assembly. Then the drill bit will install the drilling tool to drill, realizing automatic replacement of drilling tools, solving the problem of manual replacement of drilling tools in the prior art, which affects production efficiency;

[0023] 2. Through the provided moving mechanism and clamping mechanism, when the PCB board is drilled, the moving mechanism drives the clamping mechanism to move forward, and the driving component in the clamping mechanism drives the clamping component to release the fixation of the PCB board through the linkage component. When the moving mechanism drives the clamping mechanism to move forward, the driving component drives the ejection component to rise, and at the same time, the push plate in the ejection component lifts the PCB board from the ejection component and pushes it forward to the rotating wheel, so that the PCB board with the hole drilled is ejected, which solves the problem of manually taking out the PCB board in the prior art;

[0024] 3. Through the provided moving mechanism and clamping mechanism, when the moving mechanism drives the clamping mechanism to move forward, the ejection assembly and the two limit plates in the clamping mechanism will be pushed up, so that the PCB board is transported to the ejection assembly, and the limit plates can limit the position of the PCB board. Then the moving mechanism drives the clamping mechanism to move backward, and the ejection assembly is lowered. The driving assembly in the clamping mechanism drives the clamping assembly to eject the PCB board on the assembly through the linkage assembly. At the same time, the adsorption holes in the ejection assembly can adsorb the PCB board on the ejection assembly, thereby realizing automatic fixing of the PCB board and solving the problem of manual fixing of the PCB board in the prior art.

[0025] 4. Through the provided clamping mechanism and loading and unloading mechanism, when the ejection component in the clamping mechanism ejects the PCB board, the ejection component will also be pushed to the rear end of the loading and unloading mechanism, so that the bottom of the conveyor belt in the loading and unloading mechanism covers the ejected PCB board, and the conveyor belt and the rotating wheel drive the PCB board to be transported to the supporting plate through the roller line. The folding plate will prevent the PCB board from being transported outside the housing by the conveyor belt, and the supporting plate will drop due to the increase in the number of PCB boards, so that the automatic unloading and stacking are realized, which solves the problem of manually taking out the PCB board in the prior art;

[0026] 5. Through the provided clamping mechanism and loading and unloading mechanism, when the conveyor belt and the rotating wheel in the loading and unloading mechanism drive the processed PCB board to be transported to the roller line, the conveyor belt and the PCB board will press the roller line, and the No. 2 T-shaped plate at the bottom of the roller line will drive the special-shaped plate and the baffle plate at the top to go down, thereby releasing the interception of the PCB board to be processed at the top of the conveyor belt, so that the PCB board to be processed is transported to the ejection assembly through the conveyor belt. After the PCB board passes through the roller line, the No. 6 spring will drive the roller line, the special-shaped plate and the baffle plate at the top to rise through the No. 2 T-shaped plate, and the baffle plate can intercept the subsequent PCB board to be processed, thereby realizing the simultaneous loading and unloading of the material, and solving the problem of manual replacement of the PCB board in the prior art;

[0027] 6. Through the set loading and unloading mechanism, when the PCB boards on the carrier plate are stacked, the four driving wheels can be installed at the bottom of the shell in conjunction with the four mounting holes, and it can be used as a trolley. When the stacked PCB boards on the carrier plate need to be taken out, the folding plate can be removed from the top of the shell to take out the stacked PCB boards. After the stacked PCB boards are taken out, the carrier plate will rise due to the elastic force of the No. 5 spring, and then the folding plate will be installed to the top of the shell, which is convenient for next use, thus realizing the use of a trolley for transporting PCB boards, and solving the problem of the need for a trolley to transport stacked PCB boards in the prior art.

[0068] Embodiment 4:

[0069] The schemes in Example 1, Example 2 and Example 3 are further introduced below in combination with specific working methods, as described below for details:

[0070] Specifically, when this two-axis full linear PCB drilling machine is working / in use:

[0071] The tool magazine assembly 204 in the mobile mechanism 2 can store various drilling tools and detect the replaced drilling tools. When the drilling tool is seriously worn, the staff will be prompted to replace it. Before each drilling, the manipulator in the drilling mechanism 4 will select a drilling tool from the tool magazine assembly 204 and place it in the installation area on one side of the magazine assembly. Then the drill bit will install the drilling tool to drill, realizing automatic replacement of drilling tools, which solves the problem of manual replacement of drilling tools in the prior art.

[0072] After the PCB board is drilled, the moving mechanism 2 drives the clamping mechanism 5 to move forward, and the driving component 502 in the clamping mechanism 5 drives the clamping component 504 to release the fixation of the PCB board through the linkage component 503. When the moving mechanism 2 drives the clamping mechanism 5 to move forward, the driving component 502 drives the ejection component 505 to rise, and at the same time, the pushing plate 5056 in the ejection component 505 lifts the PCB board from the ejection component 505 and pushes it forward to the rotating wheel 5052, so that the PCB board with the drilled hole is ejected;

[0073] When the moving mechanism 2 drives the clamping mechanism 5 to move forward, the ejection component 505 and the two limit plates 506 in the clamping mechanism 5 are pushed up, so that the PCB board is transported to the ejection component 505, and the limit plates 506 can limit the position of the PCB board. Then the moving mechanism 2 drives the clamping mechanism 5 to move backward, and the ejection component 505 is lowered. The driving component 502 in the clamping mechanism 5 drives the clamping component 504 to eject the PCB board on the ejection component 505 through the linkage component 503. At the same time, the adsorption holes 5053 in the ejection component 505 can adsorb the PCB board on the ejection component 505, thereby realizing automatic fixing of the PCB board.

[0074] When the ejection component 505 in the clamping mechanism 5 ejects the PCB board, the ejection component 505 will also be pushed to the rear end of the loading and unloading mechanism 6, so that the bottom of the conveyor belt in the loading and unloading mechanism 6 covers the ejected PCB board, and the conveyor belt and the rotating wheel 5052 drive the PCB board to be transported to the supporting plate 604 through the roller line 606. The folding plate 612 will prevent the PCB board from being transported to the outside of the housing 601 by the conveyor belt. The supporting plate 604 will drop due to the increase in the number of PCB boards, thereby realizing automatic unloading and stacking.

[0075] When the conveyor belt and the rotating wheel 5052 in the loading and unloading mechanism 6 drive the processed PCB board to be transported to the roller line 606, the conveyor belt and the PCB board will press the roller line 606 downward, and the second T-shaped plate 607 at the bottom of the roller line 606 will drive the special-shaped plate 609 and the baffle 610 at the top to descend, so as to release the interception of the PCB board to be processed on the top of the conveyor belt, so that the PCB board to be processed is transported to the ejection component 505 through the conveyor belt. After the PCB board passes through the roller line 606, the sixth spring 608 will drive the roller line 606, the special-shaped plate 609 and the baffle 610 at the top to rise through the second T-shaped plate 607, and the baffle 610 can intercept the subsequent PCB board to be processed, so as to realize the simultaneous loading and unloading of the material;

[0076] When the PCB boards on the supporting plate 604 are stacked, the four driving wheels 602 can be installed at the bottom of the shell 601 in conjunction with the four mounting holes 611, and it can be used as a trolley. When the stacked PCB boards on the supporting plate 604 need to be taken out, the folding plate 612 can be removed from the top of the shell 601 to take out the stacked PCB boards. After the stacked PCB boards are taken out, the supporting plate 604 will rise due to the elastic force of the No. 5 spring 605, and then the folding plate 612 can be installed on the top of the shell 601, which is convenient for next use, thus realizing the transformation into a trolley for transporting PCB boards.
