The operation process is cumbersome and time-consuming, which is not conducive to continuous production and results in low drilling efficiency for circuit boards. Utility Model Content

[0003] The main objective of this application is to provide a circuit board drilling device, which aims to solve the technical problems of the prior art, which requires manual placement and removal of circuit boards one by one, resulting in a cumbersome and time-consuming operation process, which is not conducive to continuous production and has low drilling efficiency.

[0004] To achieve the above objectives, this application provides a circuit board drilling device, comprising:

[0005] A workbench equipped with a punching assembly;

[0006] A movable component is disposed below the drill bit of the drilling assembly;

[0007] Wherein, the moving part is provided with a support frame at the first end and / or the second end along the first direction, the workbench is provided with a feeding cylinder, multiple circuit boards are stacked inside the feeding cylinder, and a locking member is provided at the lower end of the feeding cylinder, the locking member being used to support the circuit boards;

[0008] The moving component is connected to a power assembly, which drives the carrier frame to move along a first direction. When the carrier frame moves towards the feeding cylinder, the locking component is unlocked by the carrier frame, so that the circuit board in the feeding cylinder can be transferred to the carrier frame. When the carrier frame moves away from the feeding cylinder, the locking component returns to the locked state, and the carrier frame moves below the drilling component to perform drilling.

[0009] Optionally, there is a discharge space between the feeding cylinder and the punching assembly;

[0010] The moving part is equipped with a tilting motor, and the output shaft of the tilting motor is connected to the support frame so that the support frame can be tilted circumferentially in the unloading space.

[0011] The side wall of the movable component is provided with a collection frame located below the support frame, the collection frame being used to receive circuit boards that fall from the support frame.

[0012] Optionally, the locking member is disposed on the side of the feeding cylinder away from the punching assembly. A positioning rod is disposed on the outer wall of the feeding cylinder. A positioning block that can move along its axial direction is sleeved on the positioning rod. A return spring is disposed on the positioning rod. The return spring is located on the side of the positioning block away from the punching assembly. A locking rod is disposed on the positioning block. The locking member is disposed on the locking rod. The locking rod can abut against the bearing frame.

[0013] Optionally, the locking rod passes through the positioning block, and the locking rod is provided with nuts located on both sides of the positioning block. The nuts are threadedly engaged with the locking rod so that the height of the locking rod in the vertical direction is adjustable.

[0017] Optionally, the support frame has a through receiving hole, and the inner wall of the receiving hole is provided with at least two support flanges, all of which are located in the same plane.

[0018] Optionally, the inner wall of the feeding cylinder has a through hole, and the outer wall of the circuit board matches the inner wall of the through hole.

[0019] Optionally, the power component is a ball screw system, wherein the screw of the ball screw system extends along the first direction.

[0020] The beneficial effects that this application can achieve are:

[0021] This application provides a circuit board drilling device. A moving component and a support frame are arranged below the drilling assembly. The moving component is connected to a power component, which enables the moving component to drive the support frame to move along a first direction. As the support frame moves closer to the feeding cylinder, it first moves below the feeding cylinder, then pushes a locking component to move, releasing the locking component from its limiting effect on the circuit board, causing the circuit board to fall onto the support frame. The support frame then moves closer to the drilling assembly to drill holes in the circuit board, thereby achieving automatic circuit board feeding. This reduces the labor intensity caused by relying on manual feeding each time and improves the feeding efficiency of the circuit board. Attached Figure Description

[0032] Example 1

[0033] Reference Figures 1-3 As shown, the first embodiment of this application provides a circuit board 51 drilling device, including:

[0034] Workbench 10, on which a punching assembly 80 is provided;

[0035] The movable part 20 is disposed below the drill bit 84 of the drilling assembly 80;

[0036] Among them, the moving part 20 is provided with a support frame 40 at the first end and / or the second end along the first direction, the workbench 10 is provided with a feeding cylinder 50, multiple circuit boards 51 are stacked inside the feeding cylinder 50, and a locking part 70 is provided at the lower end of the feeding cylinder 50, which is used to support the circuit boards 51.

[0037] The moving part 20 is connected to the power component 60, which drives the carrier frame 40 to move in the first direction. When the carrier frame 40 moves in the direction close to the feeding cylinder 50, the locking part 70 is unlocked by the carrier frame 40, so that the circuit board 51 in the feeding cylinder 50 can be transferred to the carrier frame 40. When the carrier frame 40 moves in the direction away from the feeding cylinder 50, the locking part 70 returns to the locked state, and the carrier frame 40 moves to the bottom of the drilling component 80 to perform drilling.

[0038] In this embodiment, as Figure 1 As shown, the first direction is the left-right direction. The movable member 20 is provided with a support frame 40 at its first end and / or second end along the first direction, which includes three cases: the first case is that the support frame 40 is provided only at the first end; the second case is that the support frame 40 is provided only at the second end; and the third case is that the support frame 40 is provided at both the first and second ends. The first end of the movable member 20 along the first direction is the left end of the movable member 20, and the second end is the right end of the movable member 20. Figure 1 A support frame 40 is provided at both the first and second ends of the moving part 20. The feeding cylinder 50 corresponds one-to-one with the support frame 40, that is, a feeding cylinder 50 is provided on the left and right sides of the punching assembly 80 respectively.

[0039] A locking element 70 is provided at the lower end of the feeding cylinder 50. The locking element 70 is plate-shaped and has sufficient rigidity to ensure that the circuit board 51 inside the feeding cylinder 50 can be supported by the locking element 70. The lower end of the feeding cylinder 50 is also an open structure. The outer wall of the circuit board 51 is adapted to the inner wall of the feeding cylinder 50 to ensure that the circuit board 51 can be stably supported above the locking element 70, preventing the circuit board 51 from falling from the end away from the locking element 70. This allows the circuit board 51 to move only in the vertical direction, ensuring that the circuit board 51 can only fall into the support frame 40 after the locking element 70 is unlocked. In the initial state, there is no circuit board 51 in the support frame 40. The support frame 40 moves to the left under the action of the moving part 20. When the support frame 40 moves to the lower end of the feeding cylinder 50, the support frame 40 continues to move to the left. When the support frame 40 comes into contact with the locking part 70, the support frame 40 pushes the locking part 70 to move to the left, and the circuit board 51 located in the feeding cylinder 50 falls into the support frame 40. It should be noted that after the circuit board 51 falls into the support frame 40, only one circuit board 51 is located inside the support frame 40. The second circuit board 51 from the bottom is located at least half its height inside the feed cylinder 50. The locking member 70 is aligned with the bottommost first and second circuit boards 51. When the support frame 40 receives the circuit board 51 and moves away from the feed cylinder 50 and towards the drilling assembly 80, the support frame 40 disengages from the locking member 70. The locking member 70 automatically moves to the right and inserts into the space between the bottommost first and second circuit boards 51 (the locking member 70 pushes the circuit board 51 inside the feed cylinder 50 upwards a portion). The bottommost circuit board 51 moves to the right with the support frame 40, while the second circuit board 51 remains inside the feed cylinder 50. The support frame 40 moves below the drilling assembly 80 to perform drilling.

[0040] Example 2

[0041] As an optional implementation, this embodiment provides a specific structure for flipping the support frame 40, including: a feeding space between the feeding cylinder 50 and the punching assembly 80; a flipping motor 21 is provided on the moving part 20, and the output shaft of the flipping motor 21 is connected to the support frame 40 so that the support frame 40 can be flipped circumferentially in the feeding space; a collection frame 22 is provided on the side wall of the moving part 20, located below the support frame 40, and the collection frame 22 is used to receive the circuit board 51 falling from the support frame 40.

[0042] Specifically, a support frame is provided on the workbench 10 to support the feeding cylinder 50. The feeding cylinder 50 is located on the left and right sides of the punching assembly 80. There is a gap between the feeding cylinder 50 and the punching assembly 80. The gap between the feeding cylinder 50 and the punching assembly 80 forms the unloading space. That is, after the circuit board 51 in the support frame 40 is punched, during the process of the support frame 40 moving from the position of the punching assembly 80 towards the feeding cylinder 50, when the support frame 40 moves to the position of the unloading space, the flipping motor 21 works and drives the support frame 40 to flip 180°. At this time, the flipping of the support frame 40 will not interfere with the feeding cylinder 50 or the punching assembly 80. After the support frame 40 flips 180°, the circuit board 51 located in the support frame 40 falls into the collection frame 22 located below it. The collection frame 22 is connected to the moving part 20, and the relative position between the collection frame 22 and the moving part 20 will not change. After the perforated circuit board 51 is transferred into the collection frame 22, the carrier frame 40 is rotated 180° by the flip motor 21 to return to its initial state, and then continues to move towards the feeding cylinder 50. The flip motor 21 can be a DD motor, which controls the carrier frame 40 to rotate 180° in a single operation.

[0043] Example 3

[0044] As an optional implementation, this embodiment provides a specific structure of a locking member 70, including: the locking member 70 is disposed on the side of the feeding cylinder 50 away from the punching assembly 80, a positioning rod 71 is disposed on the outer wall of the feeding cylinder 50, a positioning block 73 that can move along its axial direction is sleeved on the positioning rod 71, a return spring 72 is disposed on the positioning rod 71, the return spring 72 is located on the side of the positioning block 73 away from the punching assembly 80, a locking rod 74 is disposed on the positioning block 73, the locking member 70 is disposed on the locking rod 74, and the locking rod 74 can abut against the bearing frame 40.

[0045] Specifically, taking the feed cylinder 50 located on the left side of the punching assembly 80 as an example, the locking member 70 is located at the lower left end of the feed cylinder 50, such as... Figure 2As shown, an installation structure is provided on the outer wall of the feeding cylinder 50. The installation structure is used to install the positioning rod 71. The positioning rod 71 is fixedly installed on the outer wall of the feeding cylinder 50. The positioning block 73 has a mounting hole through which the positioning rod 71 passes. It should be noted that there are two positioning rods 71, and the axes of the two positioning rods 71 ​​are parallel to each other. By setting a return spring 72, the moving block always has a tendency to move to the right. When the bearing frame 40 moves to the left, the bearing frame 40 can abut against the locking rod 74. The bearing frame 40 pushes the locking rod 74 to move to the left, that is, at this time the locking member 70 also moves to the left. After the locking member 70 moves to the left side of the circuit board 51, the circuit boards 51 stacked in the feeding cylinder 50 move downward. The first circuit board 51 from bottom to top enters the bearing frame 40, and the lower end face of the second circuit board 51 abuts against the upper end face of the first circuit board 51. At least half of the height of the second circuit board 51 is located in the feeding cylinder 50. The locking element 70 is plate-shaped and has a certain rigidity to ensure that it can support all the circuit boards 51. After the circuit board 51 is transferred into the support frame 40, the moving part 20 drives the support frame 40 to move to the right. At this time, the positioning block 73 also moves to the right under the action of the return spring 72. The locking element 70 moves to the right and inserts into the gap between the first circuit board 51 and the second circuit board 51. During the continuous movement of the support frame 40, the second circuit board 51 is separated from the first circuit board 51. The weight of the second circuit board 51 and the circuit board 51 at the upper end of the second circuit board 51 are transferred to the locking element 70. It should be noted that there are usually components on the circuit board 51, meaning that the two circuit boards 51 will not be completely fitted together. Even if the gap between the two circuit boards 51 is small, the locking member 70 is in the shape of a sheet. Under the action of the return spring 72, it is inserted into the position between the first circuit board 51 and the second circuit board 51. The locking member 70 pushes the second circuit board 51 to move upward a certain distance, ensuring that the locking member 70 can move to the bottom of the second circuit board 51.

[0046] Optionally, the locking rod 74 passes through the positioning block 73, and the locking rod 74 is provided with nuts 75 located on both sides of the positioning block 73. The nuts 75 are threadedly engaged with the locking rod 74 so that the height of the locking rod 74 in the vertical direction is adjustable.

[0047] Specifically, the locking rod 74 passes through the positioning block 73, and the relative height of the locking rod 74 is adjusted by two nuts 75. This ensures that the relative height of the locking member 70 can be adjusted for different thickness specifications, guaranteeing that the locking member 70 can be inserted into the space between the first circuit board 51 and the second circuit board 51. It should be noted that the above-mentioned different thickness specifications refer to different batches. Within the same batch, circuit boards 51 of the same specification are preferred to reduce the frequency of conditional changes to the locking member 70.

[0048] Optionally, the outer wall of the support frame 40 is provided with an unlocking block 42, which can abut against the locking rod 74 to drive the locking member 70 to move.

[0049] Specifically, by adding an unlocking block 42, it is ensured that the unlocking block 42 can form a limiting structure with the unlocking rod. When the carrier frame 40 moves in the direction close to the feeding cylinder 50, the unlocking block 42 pushes the locking rod 74 to move. The size of the unlocking block 42 can be replaced to ensure that when the locking part 70 is disengaged from the circuit board 51, the circuit board 51 can fall vertically into the carrier frame 40.

[0050] Example 4

[0051] As an optional implementation, this embodiment provides a side guard plate 30 structure, including: side guard plates 30 located on both sides of the movable member 20 are provided on the workbench 10, and a supporting flange 31 is provided on one side wall of the two side guard plates 30 facing each other, the supporting flange 31 is used to support the bearing frame 40.

[0052] Specifically, by setting a side guard plate 30, on which a support flange 31 is provided, when the bearing frame 40 moves below the drilling assembly 80 to drill holes, the support flange 31 can play an auxiliary support role for the bearing frame 40, thereby improving the structural stability of the bearing frame 40.

[0053] Optionally, the drilling assembly 80 includes a fixing plate 82, which is connected to two side guard plates 30. A hydraulic cylinder 81 is provided on the fixing plate 82, and a drilling motor 83 is provided on the telescopic shaft of the hydraulic cylinder 81. A drill bit 84 is provided on the drilling motor 83.

[0054] Specifically, the fixed plate 82 provides support for the hydraulic cylinder 81, the drilling motor 83, and other structures. The hydraulic cylinder 81 facilitates control of the lifting and lowering movement of the drilling motor 83. Furthermore, an elastic clamping structure can be installed at the lower end of the drilling motor 83. When the drill bit 84 drills a hole in the circuit board 51, the elastic clamping structure provides auxiliary clamping to the circuit board 51, reducing the possibility of accidental displacement of the circuit board 51.

[0055] Optionally, the support frame 40 has a through receiving hole, and the inner wall of the receiving hole is provided with at least two support flanges 41, all of which are located in the same plane.

[0056] Specifically, the support flange 41 supports the circuit board 51. The area below the hole in the circuit board 51 is hollow, and some of the debris generated by the drilling can fall directly into the support frame 40 through the receiving hole.

[0057] Optionally, the inner wall of the feeding cylinder 50 has a through hole, and the outer wall of the circuit board 51 matches the inner wall of the through hole.

[0058] Specifically, by matching the outer wall of the circuit board 51 with the inner wall of the through hole, the left end of the circuit board 51 is supported by the locking member 70, and the left and right ends of the circuit board 51 form a limiting structure with the lower inner wall of the feeding cylinder 50, ensuring that when the circuit board 51 falls from the lower end of the feeding cylinder 50, the circuit board 51 only moves in the vertical direction. This reduces the possibility that the left end of the circuit board 51 is supported by the locking member 70, while the right end has no point of force, and the circuit board 51 may slip off from the right end.

[0059] Optionally, the power assembly 60 is a ball screw system, with the screw of the ball screw system extending along a first direction.

[0060] Specifically, the ball screw system of the power assembly 60 is a conventional technology to realize the left and right reciprocating motion of the moving block through the ball screw system. Similarly, the power assembly 60 can be connected to hydraulic cylinders, hydraulic cylinders, etc.

[0061] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
