Description

Technical Field

[0001] This utility model relates to the field of electronic component manufacturing technology, specifically to a circuit board drilling device for electronic components. Background Technology

[0002] Existing electronic component circuit board drilling equipment is a specialized device used to process mounting holes on printed circuit boards. Its basic structure includes a frame, worktable, drill chuck, and drive system. These devices typically use a high-speed spindle motor to drive the drill bit, achieving relative motion positioning between the drill bit and the circuit board through mechanical transmission or a servo system. Current development trends in drilling equipment focus on two main aspects: high precision and high efficiency. In terms of precision, linear motors and linear encoders are used for precision transmission and detection components, achieving positioning accuracy down to the micrometer level. In terms of efficiency, automatic tool change systems and multi-spindle designs enable continuous processing. The industry widely uses carbide and tungsten carbide drill bits, with drilling diameters typically ranging from 0.1mm to 6.5mm and rotational speeds reaching 160,000 revolutions per minute. To meet the demands of high-density interconnected circuit boards, modern equipment also integrates vision positioning systems and laser rangefinders to ensure drilling position accuracy.

[0003] Existing circuit board drilling equipment generally uses a single drill bit structure. Changing the drill bit requires manual disassembly and installation, which is cumbersome, time-consuming, and prone to damaging the drill chuck. Drilling position adjustment largely relies on manual operation, resulting in low positioning accuracy and poor repeatability. Traditional equipment lacks a drill bit management system, requiring operators to frequently search for and replace drill bits, impacting work efficiency and increasing the risk of incorrect drill bit selection due to human error. Furthermore, ordinary drilling machines lack sufficient positioning stability, easily leading to deviations during drilling and affecting the relative positional accuracy between holes. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board drilling device for electronic components, comprising a working board, with positioning devices on the left and right sides of the working board, and a drilling device at the bottom of the positioning devices. The positioning devices include longitudinal positioning seats, which are fixedly installed on the left and right sides of the working board. A longitudinal positioning screw is rotatably installed inside the left longitudinal positioning seat, and a longitudinal positioning motor is fixedly installed at the front end of the left longitudinal positioning seat. The output end of the longitudinal positioning motor passes rearward through the longitudinal positioning seat and is fixedly installed at the front end of the longitudinal positioning screw. A longitudinal guide post is fixedly installed inside the right longitudinal positioning seat, and a positioning bridge is threaded onto the external thread of the positioning screw. The right end of the positioning bridge is slidably installed inside the longitudinal guide post. A transverse rack is fixedly installed at the top of the positioning bridge, and a transverse positioning seat is slidably installed at the top of the positioning bridge. A transverse motor is fixedly installed near the top of the transverse positioning seat, and a transverse gear is rotatably installed inside the transverse positioning seat above the transverse rack. The output end of the transverse motor passes through the transverse positioning seat and is rotatably installed at the front end of the transverse gear.

[0006] Preferably, the beams and columns of the positioning bridges on both sides are designed with protrusions that overlap the top sides of the working plate. This helps to distribute the weight of the entire device and ensures smooth longitudinal movement.

[0007] Preferably, the top cross-section of the positioning bridge is trapezoidal to distribute the weight of the segmented lateral positioning seats, thus ensuring smooth lateral movement.

[0008] Preferably, the drilling device includes a drill bit changing assembly and a drilling assembly, wherein the drill bit changing assembly is disposed on the rear side of the bottom of the transverse positioning seat, and the drilling assembly is disposed on the front side of the bottom of the transverse positioning seat.

[0009] Preferably, the drill bit changing assembly includes a base column, which is fixedly installed on the rear side of the bottom of the transverse positioning seat. A drill bit changing motor is fixedly installed on the bottom of the base column. A drill bit changing rotating shaft is fixedly installed on the output end of the drill bit changing motor. A drill bit plate is keyed to the side of the drill bit changing rotating shaft away from the drill bit changing motor. A drill bit sliding seat is slidably installed on the outer ring of the drill bit plate. A sliding spring is fixedly installed between the bottom of the drill bit sliding seat and the drill bit plate. A drill bit bearing is fixedly installed inside the drill bit sliding seat. A drilling drill bit is fixedly installed on the inner ring of the drill bit bearing. A one-way locking transmission seat is fixedly installed on the top of the drilling drill bit.

[0010] Preferably, the drill bit sliding seat, sliding spring, drill bit bearing, drilling drill bit, and one-way locking transmission seat are provided in six sets, and are distributed in a circular array within the drill bit plate with the drill bit changing rotation shaft as the center.

[0011] Preferably, the drilling assembly includes a drilling base plate, which is fixedly installed on the front side of the bottom of the transverse positioning seat. A drilling electric telescopic rod is fixedly installed on the bottom of the drilling base plate. A drilling guide post is fixedly installed on the drilling base plate around the drilling electric telescopic rod. A drilling movable plate is fixedly installed at the output end of the drilling electric telescopic rod. The drilling guide post is slidably installed inside the drilling movable plate. A drilling motor is fixedly installed at the bottom of the drilling movable plate. A drilling drive shaft is fixedly installed at the output end of the drilling motor. A one-way locking active seat is fixedly installed at the bottom of the drilling drive shaft.

[0012] Preferably, the one-way locking drive seat and the one-way locking transmission seat are engaged in one-way engagement.

[0013] Compared with the prior art, the present invention provides a circuit board drilling device for electronic components, which has the following advantages:

[0014] 1. This electronic component circuit board drilling device features a design that separates the drill bit changing assembly from the drilling assembly. In actual operation, when it is necessary to change to a drill bit of a different diameter, the drilling motor drives the one-way locking active seat to reverse and disengage from the one-way locking transmission seat on the drill bit. Subsequently, the drill bit changing motor can drive the drill bit plate to rotate, quickly moving the required drill bit to the working position. This achieves rapid switching between multiple drill bit specifications, reduces downtime for changing drill bits, and improves the efficiency of drilling operations.

[0015] 2. The circuit board drilling device for electronic components is designed with a transverse rack and transverse gear meshing transmission and a transverse positioning seat sliding installation. In actual operation, it can drive the drilling device to move precisely laterally along the positioning bridge. Combined with the longitudinal positioning screw driving the longitudinal movement of the positioning bridge, it realizes the precise positioning of the drilling operation within the plane range and ensures the processing accuracy of the circuit board hole positions.

[0026] Example 1:

[0027] Please see Figure 1-6This utility model provides a technical solution: a circuit board drilling device for electronic components, including a working board 1, positioning devices 2 on the left and right sides of the working board 1, and a drilling device 3 at the bottom of the positioning devices 2.

The output end of the transverse motor 28 passes through the transverse positioning seat 27 and is rotatably installed at the front end of the transverse gear 29.

[0028] Furthermore, it was found that the beams and columns of the positioning bridges 25 on both sides are designed with protrusions overlapping the top sides of the working plate 1. This is to share the weight of the entire device and make longitudinal movement smooth.

[0029] Furthermore, the top cross-section of the positioning bridge 25 is trapezoidal, which allows for smooth lateral movement by dividing the weight of the lateral positioning seat 27 into segments.

[0030] Example 2:

[0031] Please see Figure 1-6 Furthermore, in conjunction with Embodiment 1, it is further found that the drilling device 3 includes a drill bit changing assembly 31 and a drilling assembly 32. The drill bit changing assembly 31 is located at the rear side of the bottom of the transverse positioning seat 27, and the drilling assembly 32 is located at the front side of the bottom of the transverse positioning seat 27.

[0032] Furthermore, the drill bit changing assembly 31 includes a base column 311, which is fixedly installed on the rear side of the bottom of the transverse positioning seat 27. A drill bit changing motor 312 is fixedly installed at the bottom of the base column 311. A drill bit changing rotating shaft 313 is fixedly installed at the output end of the drill bit changing motor 312. A drill bit plate 314 is keyed to the side of the drill bit changing rotating shaft 313 away from the drill bit changing motor 312. A drill bit sliding seat 315 is slidably installed on the outer ring of the drill bit plate 314.

[0033] Furthermore, it is found that six sets of drill bit sliding seat 315, sliding spring 316, drill bit bearing 317, drilling drill bit 318, and one-way locking transmission seat 319 are provided, and are distributed in a circular array within the drill bit plate 314 with the drill bit changing rotation shaft 313 as the center.

[0034] Furthermore, the drilling assembly 32 includes a drilling base plate 321, which is fixedly installed on the front side of the bottom of the transverse positioning seat 27. A drilling electric telescopic rod 322 is fixedly installed on the bottom of the drilling base plate 321.

A one-way locking active seat 327 is fixedly installed at the bottom of the drilling drive shaft 326.

[0035] Furthermore, it is found that the one-way locking drive seat 327 and the one-way locking transmission seat 319 engage in one-way engagement.

[0036] In actual operation, when this device is used, the circuit board to be processed is first fixed on the working plate 1. The longitudinal positioning motor 23 drives the longitudinal positioning screw 22 to rotate, which drives the positioning bridge 25 to move longitudinally. At the same time, the transverse motor 28 drives the transverse gear 29 to rotate, which, through meshing with the transverse rack 26, drives the transverse positioning seat 27 to move laterally along the positioning bridge 25, thereby accurately positioning the drilling device 3 above the target hole. When it is necessary to change the specification of the drilling bit 318, the drilling motor 325 reverses to disengage the one-way locking active seat 327 from the one-way locking transmission seat 319 of the current drill bit. The drill bit changing motor 312 starts and drives the drill bit plate 314 to rotate, rotating the drilling bit 318 of the required specification to the working position. The drilling motor 325 rotates forward to complete the engagement and locking of the new drilling bit 318. After positioning is completed, the electric telescopic rod 322 is activated to push the drilling assembly 32 downward. At the same time, the drilling motor 325 rotates at high speed to drive the drilling bit 318 to perform drilling operations. After reaching the set depth, it retracts to complete the processing of one hole.
