DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The utility model discloses a drilling device for processing circuit boards, including a moving mechanism 1 and a drilling mechanism 2. The moving mechanism 1 includes a slide plate 11. Both ends of the slide plate 11 are movably sleeved with fixed shafts 12 through sliding sleeves 111. A limiting groove 121 is provided on the top of the fixed shaft 12. A limiting groove 2 13 is provided on the top of the slide plate 11. A driving rod 14 is movably provided inside the limiting groove 2 13. Both ends of the driving rod 14 are provided with locking heads 15, whose bottom ends extend to the inside of two limiting grooves 121 respectively.

[0027] The drilling mechanism 2 includes a slider 21 movably mounted on the slide plate 11, a locking block 22 and a bevel block 26 located on the top of the locking block 22 are movably arranged inside the slider 21, the bottom of the locking block 22 extends to the inside of the limiting groove 13, and a pull plate 27 is arranged on one side of the bevel block 26 through a pull rod.

[0028] Specifically, a handle 29 is provided at one end of the slider 21, and the end of the pull rod away from the inclined block 26 extends to the inside of the handle 29. When in use, the user holds the handle 29 to move the slider 21 left and right on the skateboard 11, or drives the skateboard 11 to move forward and backward on the fixed axis 12 through the slider 21, so as to accurately align the drill bit with the drilling position.

[0029] Specifically, a plurality of protrusions are provided at the bottom of the locking head 15, the bottom of the locking block 22, the bottom of the inner wall of the limiting groove 121 and the top of the driving rod 14. The protrusions are provided to increase the friction between the locking head 15 and the limiting groove 121 and the friction between the driving rod 14 and the locking block 22.

[0030] Specifically, a spring 17 whose top end contacts the bottom of the driving rod 14 is embedded at the bottom of the inner wall of the second limiting groove 13, and springs 24 are arranged on both sides of the locking block 22. A spring 3 28 is arranged on the side of the pull plate 27 away from the pull rod. The user adjusts the position of the motor 212 and the drill bit through the handle 29. After the adjustment is completed, the user pulls the pull plate 27 relative to the handle 29, and the pull plate 27 compresses the spring 3 28. At the same time, the pull plate 27 drives the inclined block 26 to move. Figure 6 As the inclined block 26 is pulled, the inclined block 26 resists the locking block 22 to descend and compresses the spring 24. At the same time, the locking block 22 resists the driving rod 14, and the driving rod 14 drives the locking head 15 to descend. At the same time, the driving rod 14 compresses the spring 17, and the locking head 15 descends and resists the bottom of the inner wall of the limiting groove 121, thereby achieving simultaneous locking of the slide plate 11 and the slider 21, and the lifting cylinder 211 and the motor 212 can be started to perform the drilling operation. The setting of the spring 17, the spring 24 and the spring 3 28 enables the locking head 15, the locking block 22 and the inclined block 26 to automatically reset after the user releases the pull plate 27.

[0031] Specifically, a lifting cylinder 211 is provided at the top of the end of the slider 21 away from the handle 29, the output end of the lifting cylinder 211 extends to the bottom of the slider 21 and is provided with a motor 212, the output end of the motor 212 is provided with a drill bit, and the bottom of the motor 212 is also provided with an infrared laser module 213 and a lighting lamp 214 located outside the drill bit. The lighting lamp 214 can illuminate the circuit board, which is convenient for users to observe. The infrared laser module 213 emits a dot-shaped mark on the circuit board, which is convenient for users to judge the descending position of the drill bit. Starting the lifting cylinder 211 drives the drill bit to descend through the motor 212, and starting the motor 212 can drive the drill bit to perform drilling operations.

[0032] Specifically, the interior of the sliding sleeve 111 is provided with a boss 112 whose bottom end extends to the interior of the limiting groove 121, and the interior of the sliding block 21 is provided with a boss 25 whose bottom end extends to the interior of the limiting groove 13. The setting of the boss 112 and the boss 25 further ensures the sliding stability between the sliding sleeve 111 and the fixed shaft 12 and the sliding stability between the sliding block 21 and the sliding plate 11.

[0033] Specifically, a stabilizing rod 16 with one end extending to the interior of the locking head 15 is provided inside the limiting groove 121, and a stabilizing rod 23 with one end extending to the interior of the locking block 22 is provided inside the sliding block 21. The setting of the stabilizing rod 16 and the stabilizing rod 23 further ensures the stability of the lifting and lowering action of the locking head 15 and the locking block 22.

[0034] Specifically, it also includes a base 3, and four supporting frames 31 opposite to each other are arranged on the top of the base 3. The two ends of the fixed shaft 12 are respectively fixedly connected to the two opposite supporting frames 31. An avoidance hole 32 is opened inside the base 3, and a clamp cylinder 33 located outside the avoidance hole 32 is also arranged on the top of the base 3. The number of the clamp cylinders 33 is not less than one, and the clamp cylinders 33 can also be replaced by conventional manual screw clamps. The circuit board to be drilled is placed on the base 3, and the drilling position is opposite to the avoidance hole 32. According to the specifications of the circuit board, each clamp cylinder 33 is controlled to extend to clamp the circuit board.

[0035] In summary, with the drilling device for processing circuit boards, the user can manually adjust the front and rear and left and right positions of the motor 212 through the handle 29. After the position is adjusted, the positions of the slider 21 and the skateboard 11 can be locked at the same time by pulling the pull plate 27. The operation process is simpler and more convenient, and the structure is streamlined and compact, which is economical and has broad application prospects.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
