[0034] The circuit board drilling device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0035] Reference Figures 1-5 The present invention aims to provide an embodiment of a circuit board drilling device. The circuit board drilling device of this embodiment mainly includes: a device body 100 and a workbench 120 fixedly installed on the device body 100. A drilling machine 110 fixedly connected to the inner side of the device body 100 is provided above the workbench 120. The workbench 120 is used for placing the circuit board, and the drilling machine 110 is used for drilling holes in the circuit board.

[0036] In some specific embodiments of this utility model, the workbench 120 is provided so that the circuit board can be placed on the workbench 120 so that drilling operations can be performed on the workbench 120.

[0037] In some specific embodiments of this utility model, the drilling machine 110 is configured to perform drilling operations on the circuit board placed on the workbench 120 through an electronic control mechanism.

[0038] In some specific embodiments of this utility model, a plurality of ejector rods 140 are slidably arranged on the workbench 120, and at least three positioning plates 130 are arranged on the workbench 120. The bottom of the positioning plate 130 is inserted into the ejector rods 140. The positioning plate 130 is used for limiting the placement of the circuit board, and the ejector rods 140 are used for the vibration ejection of the circuit board. A plurality of positioning pins 150 are fixedly arranged on each positioning plate 130. The positioning pins 150 are used for guiding the placement of the circuit board.

[0039] In some specific embodiments of this utility model, the positioning plate 130 can be set so that the circuit board can be positioned and guided by the positioning pin 150 when it is placed, thereby facilitating the placement of the circuit board by the staff.

[0040] In some specific embodiments of this utility model, after the drilling machine 110 finishes drilling the circuit board, it can be ejected by the vibration of the ejector rod 140, so that the circuit board and the positioning pin 150 are separated in advance, thereby facilitating the disassembly of the circuit board and the positioning placement plate 130 by the staff.

[0041] In some specific embodiments of this utility model, an ejection mechanism is also included. The ejection mechanism includes a fixed base 160 fixedly connected to the bottom of the device body 100, an actuating rod 220 slidably connected to the inside of the fixed base 160, and a drive ring 230 for actuating the actuating rod 220. Each actuating rod 220 is fixedly provided with a connecting rod 250 on both sides. Each connecting rod 250 is fixedly provided with a spring 190. The spring 190 is used to push the actuating rod 220 upward. Each fixed base 160 is fixedly provided with a connecting seat 240 on the upper half of one side. The connecting seat 240 is fixedly connected to the end of the spring 190 away from the connecting rod 250.

[0042] In some specific embodiments of this utility model, when the drive ring 230 rotates, its arc-shaped side will push the connecting rod 250 downward. During the downward movement of the connecting rod 250, it will pull the spring 190 to extend. When the drive ring 230 rotates to the notch, its surface will no longer push the connecting rod 250. Then, the connecting rod 250 can be quickly reset by the elastic force of the spring 190, thereby driving the push rod 220 fixedly connected to the connecting rod 250 to move upward quickly.

[0043] In some specific embodiments of this utility model, during the above process, the jacking rod 220 moves downward together with the connecting rod 250, so that when the connecting rod 250 is not under force, the jacking rod 220 can move upward quickly.

[0044] In some specific embodiments of this utility model, one end of the spring 190 is fixedly connected to the fixed base 160 via the connecting seat 240, so that when the connecting rod 250 moves downward, it can pull the spring 190 to extend.

[0045] In some specific embodiments of this utility model, the spring 190 is tilted because the connecting seat 240 protrudes.

[0046] In summary, firstly, this embodiment can utilize the positioning plate 130 to position and guide the placement of the circuit board using the positioning pin 150, thereby facilitating the placement of the circuit board by the staff.

[0047] Secondly, after the drilling machine 110 finishes drilling the circuit board, it can be ejected by the vibration of the ejector rod 140, so that the circuit board is separated from the positioning pin 150 in advance, thereby facilitating the disassembly of the circuit board and the positioning plate 130 by the staff.

[0048] When the ejector mechanism moves, the drive ring 230 rotates, and its arc-shaped side pushes the connecting rod 250 downward. During the downward movement, the connecting rod 250 pulls the spring 190 to extend. When the drive ring 230 rotates to the notch, its surface will no longer push the connecting rod 250. As a result, the connecting rod 250 can quickly return to its original position by the elastic force of the spring 190. In this way, the push rod 220, which is fixedly connected to the connecting rod 250, can move upward quickly.

[0049] In some specific embodiments of this utility model, each jacking rod 220 may be fixedly provided with a top ejector plate 170, and each ejector plate 170 may be fixedly connected to a plurality of vertically arranged ejector short rods 140.

[0050] It is easy to understand that in this embodiment, each column of ejector rods 140 is connected to an ejector mechanism via an ejector plate 170, thereby enabling one ejector mechanism to eject multiple ejector rods 140.

[0051] In some specific embodiments of this utility model, a drive motor 180 can be fixedly installed on one side of the fixed base 160, and a transmission rod 210 can be fixedly installed at the output end of the drive motor 180. The transmission rod 210 passes through multiple fixed bases 160, and there are twelve fixed bases 160. Every four fixed bases 160 form a group, and each group of fixed bases 160 is located below each positioning plate 130. The outer side of each group of fixed bases 160 is fixedly connected to the drive motor 180 through a mounting box.

[0052] Each drive ring 230 is fixedly connected to the transmission rod 210. The drive ring 230 is rotatably mounted on one side of the fixed base 160. The transmission rod 210 is used to drive the rotation of multiple drive rings 230.

[0053] It is easy to understand that in this embodiment, when the drive motor 180 is turned on, it can drive the transmission rod 210 to rotate through its output end, thereby driving the drive ring 230 fixedly connected to it to rotate. In this way, the drive ring 230 can be used to implement the ejection vibration effect of the above-mentioned ejection mechanism.

[0054] It should be noted that the drive ring 230 rotates around the transmission rod 210 as the center, for reference... Figure 5 The position of the transmission rod 210 is not at the axis of the drive ring 230, therefore, the drive ring 230 rotates eccentrically when it rotates;

[0055] It should be noted that the three sets of fixed bases 160 correspond to three positioning plates 130, so that the operator can push out one of the positioning plates 130 by controlling one of the drive motors 180 individually.

[0056] In some specific embodiments of this utility model, each fixed base 160 may be provided with a sliding groove 200, and the connecting rod 250 may extend to the outside of the fixed base 160 through the sliding groove 200.

[0057] It is easy to understand that in this embodiment, the opening of the slide groove 200 allows the connecting rod 250 to be slidably connected to the fixed base 160 through the slide groove 200, and can extend through the slide groove 200 to the outside of the fixed base 160 to contact one side of the drive ring 230.

[0058] In some specific embodiments of this utility model, each drive motor 180 can be individually controlled by a controller.

[0059] It is easy to understand that in this embodiment, when an operator needs to control a certain drive motor 180, he / she can directly control it through the controller so that the corresponding positioning plate 130 can be pushed.

[0060] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0061] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
