[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] The present invention specifically discloses a circuit board motherboard drilling device, such as Figure 1-Figure 4 As shown, it includes: a fuselage 1 with a protective cover 100, multiple drilling machines 101 required for drilling are installed on the inner side wall of the fuselage 1, the fuselage 1 includes a digital operating system and a dual-axis driving device, the drilling machine 101 is installed on the dual-axis driving device to achieve up and down and left and right movement, and the protective cover 100 is closed during drilling work, which can separate the processing area inside the fuselage 1 from the outside. A feeding device 2 is installed on the fuselage 1 below the drilling machine 101. The feeding device 2 is a screw transmission device. The feeding device 2 is mainly used to drive the feeding table 3 connected thereto. After the substrate 500 to be drilled is fixed on the feeding table 3, the feeding device 2 drives the feeding table 3 to achieve translation, so as to cooperate with the drilling machine 101 above to complete the drilling operation on different drilling positions on the substrate 500.

[0048] according to Figure 3 and Figure 4 As shown, a mounting groove 31 is provided on the feed table 3, and the transmission drive frame 4 is escalably mounted in the mounting groove 31 through a first elevating push block 41 mounted at the bottom, and the transmission drive frame 4 is lifted and lowered in the mounting groove 31 by the first elevating push block 41. Among them, a plurality of transmission drive frames 4 are arranged in intervals in the mounting groove 31 to match the number of drilling machines 101. In this embodiment, four drilling machines 101 are taken as an example, and correspondingly, four groups of transmission drive frames 4 are also arranged, and the positions of the transmission drive frames 4 and the drilling machines 101 correspond to each other. The transmission drive frame 4 is a frame body composed of two groups of synchronous conveyor belts to achieve high-precision transmission.

[0049] according to Figure 2 As shown, through side supply plate channels 6 are opened on the side walls on the left and right sides of the fuselage 1. The two side supply plate channels 6 are two channels with different functions, one for entry and one for exit. For example, the right side is the channel for the substrate 500 to enter the fuselage 1 for processing, and the left side is the channel for the substrate 500 to be sent out of the fuselage 1 after drilling is completed. When the feed table 3 moves to a position matching the side supply plate channel 6, the conveying drive frame 4 is lifted by the first lifting push block 41 to a height exceeding the table top of the feed table 3, and all the conveying drive frames 4 are at the same height, and the substrate 500 that needs to be drilled enters from the entry channel and is placed on the conveying drive frame 4, and the substrate 500 is transported from right to left by the conveying drive frame 4. After the substrate 500 moves to the leftmost position, the conveying drive frame 4 fine-tunes and corrects the processing position, and then the conveying drive frame 4 at this position begins to descend until the substrate 500 completely falls on the feed table 3, and the subsequent substrates 500 are transmitted in turn, and after reaching the designated matching processing position, the conveying drive frame 4 descends so that the substrate 500 completely falls on the feed table 3.

[0050] according to Figure 3 As shown, positioning holes 5 are provided on the feed table 3 below each substrate 500. When the pin 501 nailed on the substrate 500 falls with the substrate 500, the pin 501 will be inserted into the positioning hole 5, and a guide bevel 51 larger than the aperture is provided at the edge of the positioning hole 5. Through the guide bevel 51, the pin 501 can be better inserted into the positioning hole 5, and through the positioning hole 5, the position where the substrate 500 falls is fixed, and the substrate 500 can be prevented from being offset during drilling, thereby ensuring the drilling accuracy. After the drilling is completed, all the transmission drive frames 4 are simultaneously raised to the same height, and start to drive the substrate 500 to be sent out from the side supply plate channel 6 on the left, while the side supply plate channel 6 on the right starts to receive a new batch of substrates 500 that need to be drilled, so as to achieve continuous feeding and drilling of the substrate 500 and improve the processing speed.

[0051] according to Figure 2 As shown, a pushing device 9 is provided in the side plate supply channel 6 on both sides, and the substrate 500 can be pushed into or pushed out of the conveying drive frame 4 through the pushing device 9; stabilizing mechanisms 11 are evenly arranged on the feed table 3, and after the substrate 500 falls on the feed table 3, the substrate 500 is clamped and fixed by the stabilizing mechanism 11, and the substrate 500 is pressed tightly on the feed table 3.

[0052] according to Figure 3 , Figure 5-Figure 7 As shown, the stabilizing mechanism 11 comprises: a receiving frame 111 evenly spaced and embedded on the feeding platform 3, a lever pressing plate 112 symmetrically hingedly provided on the receiving frame 111, and a lever connecting portion 1121 extending at a 45-degree angle is provided on the lever pressing plate 112. Figure 6 As shown, the lever connecting part 1121 is slidably connected with the two lever connecting parts 1121 in a state where both ends are bent downward, and a second lifting push block 114 is fixedly installed in the receiving frame 111. The movable part of the second lifting push block 114 is connected to the bottom of the arc-shaped push-pull frame 113, and the arc-shaped push-pull frame 113 is lifted and lowered by the second lifting push block 114 at the bottom. When the substrate 500 is transported, the buffer plate can be stacked on top of the substrate 500. Figure 7 As shown, when the substrate 500 has not completely landed on the feeding table 3, the lever pressing plate 112 is kept in an upright state by pulling down the arc-shaped push-pull frame 113 through the second lifting push block 114. After the substrate 500 has completely landed on the feeding table 3, Figure 6 As shown, the lever pressing plate 112 can push the arc-shaped push-pull frame 113 upward to swing to a straight state through the second lifting push block 114. When the lever pressing plate 112 is flat, it will tightly press the substrate 500 and the buffer plate to prevent the substrate 500 from moving up and down, so there is no need to fix the buffer plate with tape. A buffer strip 115 is provided at the edge of the lever pressing plate 112. The function of the buffer strip 115 is to prevent the lever pressing plate 112 from buffering when pressing the substrate 500, so as to avoid damaging the substrate 500 and leaving dents.

[0053] It should be noted that the arc-shaped push-pull frame 113 is configured to have a certain curvature in order to better enable the two lever pressure plates 112 to close the bottom lever connecting parts 1121 together when the two lever pressure plates 112 are in the upright state. If the arc-shaped push-pull frame 113 is in a straight state, then when the two lever pressure plates 112 are in the upright state, the arc-shaped push-pull frame 113 pushes the lever connecting parts 1121 upward and the two will not slide against each other, and the two lever connecting parts 1121 cannot be brought close to each other. Setting the arc-shaped push-pull frame 113 to a curved shape can avoid this problem.

[0054] according to Figure 8 , Fig. 9 and Fig.12 As shown, it also includes: a side cover door 7 is installed on the side supply plate channel 6 through a hinge. When in use, the side cover door 7 can be opened to expose the side supply plate channel 6. A lifting device 8 is fixedly installed on the side cover door 7. When not in use, the lifting device 8 is hidden in the side supply plate channel 6 as the side cover door 7 is closed, and a loading frame 12 is hung on the lifting device 8. Partitions 122 are evenly spaced on both sides of the loading frame 12. The substrate 500 that needs to be drilled is inserted into the loading frame 12 through the gap between the partitions 122. As the lifting device 8 drives the loading to slowly descend, the pushing device 9 is used to push the substrates 500 one by one from the bottom of the loading frame 12 to the conveying drive frame 4. In accordance with Fig.13As shown, since the loading frame 12 is hung on the lifting device 8, and the lifting device 8 depends on the side cover door 7, the overall load-bearing capacity of the side cover door 7 is limited. By opening a plurality of hollow holes 121 on the loading frame 12 to reduce the weight of the frame, the load-bearing burden of the side cover door 7 can be reduced. The substrate 500 to be drilled is formed by stacking sheets of substrates 500, and a cardboard is placed at the bottom, a buffer plate is placed on the top layer, and finally fixed together by pins 501. After being placed in the loading frame 12, in order to prevent the substrate 500 from bending and falling down in the middle of the suspension, an anti-slip groove 123 is opened downward on the partition 122, and the pin 501 on the substrate 500 placed in the loading frame 12 will slide into the anti-slip groove 123, so that the substrate 500 can be prevented from bending and falling down in the middle of the suspension.

[0055] according to Fig. 9 , Fig.12 and Fig.13 As shown, the lifting device 8 includes: a lifting guide rail 81 fixedly installed on the side cover door 7, a moving block 82 driven by the lifting guide rail 81, a hanging plate 83 fixedly installed on the moving block 82, and protruding hooks 84 are evenly spaced on the surface of the hanging plate 83. A hook groove 85 matching the hook 84 is opened on the loading frame 12. The loading frame 12 filled with substrates 500 is hung on the hanging plate 83 through the hook groove 85, and then the lifting guide rail 81 drives the moving block 82 to move up and down with the hanging plate 83, thereby driving the loading frame 12 to move.

[0056] according to Fig. 9 and Fig.10As shown, the pushing device 9 includes: a linear drive 90 swingingly set in the side supply plate channel 6, the linear drive 90 is a linear guide rail, and a push plate 92 is driven on the linear drive 90 on one side. When not in use, the linear drive 90 is swung upright and placed in the side supply plate channel 6. When in use, it is swung to a straight state, and a substrate 500 is suspended above. As the loading frame 12 moves downward, the push plate 92 is driven by the linear drive 90 to push the substrate 500 to move to the transmission drive frame 4. A roller frame 91 is provided in the side supply plate channel 6 on the same side as the push plate 92. The purpose of setting the roller frame 91 is that the push plate 92 needs to pass through the side supply plate channel 6 when pushing the substrate 500 into the transmission drive frame 4, and there is no transmission drive frame 4 in the side supply plate channel 6, so the roller frame 91 is used as a support transition to allow the substrate 500 to slide onto the transmission drive frame 4. The linear drive 90 on the other side drives a lifting base 93 to be set, and an adsorption plate 94 is driven to be installed on the lifting base 93. A plurality of adsorption air holes are provided on the upper surface of the adsorption plate 94. The substrate 500 with holes drilled is transported toward the exit of the side supply plate channel 6, and falls on the adsorption plate 94 as it is transported by the conveying drive frame 4. After the substrate 500 is adsorbed by the adsorption air holes, the lifting base 93 is slightly lifted to lift the substrate 500 from the conveying drive frame 4, and then the lifting base 93 is driven by the linear drive 90 to move to the bottom of the loading frame 12, and the substrate 500 that follows the movement is inserted into the loading frame 12.

[0057] Among them, the difference between the push plate 92 and the adsorption plate 94 is that the push plate 92 pushes the substrate 500 onto the conveying drive frame 4 by pressing against the edge of the substrate 500. This process is to send the substrate 500 from the outside of the fuselage 1 to the inside of the fuselage 1 for drilling processing. Therefore, the push plate 92 does not need to enter an area that is too deep to push the substrate 500 onto the conveying drive frame 4; and when the drilled substrate 500 is sent out of the fuselage 1 from the conveying drive frame 4, due to the structure of the linear drive 90, it cannot extend to the feed table 3 to push the substrate 500 out by pressing against the edge of the substrate 500. Therefore, the substrate 500 can only be taken out of the conveying drive frame 4 by adsorption and lifting.

[0058] The side cover door 7 and the lifting device 8 provided on the side of the fuselage 1 of the present invention can be directly opened for operation when in use, and the loading frame 12 loaded with sheet materials is hung on the lifting device 8, and the sheet materials are intermittently pushed to the conveying drive frame 4 through the pushing device 9, so as to achieve an orderly automatic feeding effect.

[0059] according to Fig. 9 and Fig.11As shown, a receiving groove 71 is provided on the fuselage 1 above the side cover door 7, and a limiting plate 72 is hingedly installed in the receiving groove 71. A clamping groove 73 is provided on the limiting plate 72. After the side cover door 7 is flipped open to ninety degrees, the limiting plate 72 is flipped open from the receiving groove 71 and rests against the top of the side cover door 7. The clamping groove 73 is clamped into a recess 74 provided on the top of the side cover door 7. The limiting plate 72 effectively limits the side cover door 7, which can prevent the side cover door 7 from bearing too much weight, causing the hinge on the side cover door 7 to bend, thereby causing the side cover door 7 to fail to close normally. At the same time, it also prevents the side cover door 7 from swinging when the loading frame 12 is loading and unloading the substrate 500.

[0060] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
