Description

Technical Field

[0001] This utility model relates to the field of circuit board drilling machine technology, and in particular to a circuit board drilling machine that is easy to load and unload. Background Technology

[0002] Circuit board drilling machines are indispensable pieces of equipment in the electronics manufacturing industry. They are primarily used to drill holes of various diameters into circuit board substrates to meet the needs of mounting component pins or achieving electrical connections between different layers. Circuit boards, also known as printed circuit boards (PCBs), are essential components of electronic devices. They serve as the support for electronic components and the carrier for their electrical interconnections. Drilling machines achieve high-precision and high-efficiency drilling operations on circuit boards by precisely controlling the position and movement of the drill bit.

[0003] Traditional CNC drilling machines for circuit boards present numerous inconveniences, particularly during the loading and unloading of circuit boards. Specifically, traditional CNC drilling machines require placing the circuit board on the drilling table and securing it with tape to prevent movement or slippage during drilling. After drilling, the operator must peel off the tape one by one and remove the circuit board from the drilling table. This process not only consumes a large amount of tape, increasing material costs, but also is time-consuming and labor-intensive, reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a circuit board drilling machine that facilitates loading and unloading, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a circuit board drilling machine that facilitates loading and unloading, including a chassis. A protective frame is fixedly installed on the top surface of the chassis. Several drilling plates are fixedly installed on the top surface of the chassis by bolts. Two symmetrically arranged sliding grooves are formed on the bottom surface of each drilling plate. Two symmetrically arranged locking grooves are formed through the top surface of each drilling plate. The two sliding grooves are located between the two locking grooves. Mounting plates are fixedly installed on the inner walls of the sliding grooves by bolts. Two symmetrically arranged springs are fixedly connected to one side of the mounting plate. A movable plate is fixedly connected to the end of each spring away from the mounting plate. The movable plate is slidably connected to the drilling plate via a groove. A retaining plate is fixedly connected to the side of the movable plate away from the spring. The top surface of the retaining plate is arc-shaped. The ends of the two retaining plates away from the movable plate are respectively located inside two locking grooves. Two symmetrically arranged locking frames are slidably connected to the inner wall of the locking groove. The two retaining plates are respectively engaged with the two locking frames. The circuit board body is embedded in the bottom surface of the drilling plate. A pressure frame is fixedly connected to the bottom end of the two locking frames. The bottom surface of the pressure frame is in contact with the top surface of the circuit board body. Control rods are slidably connected to both sides of the drilling plate. The control rods are fixedly connected to the movable plate.

[0007] Preferably, in any of the above embodiments, a positioning pin is fixedly connected to the bottom surface of the drilling plate, and a positioning hole is provided on the top surface of the chassis, and the positioning pin is slidably connected to the chassis through the positioning hole.

[0008] Preferably, as described in any of the above embodiments, the top surface of the drill plate is provided with an embedding groove, and the circuit board body is slidably connected to the drill plate through the embedding groove.

[0009] Preferably, in any of the above embodiments, through holes are provided on both the left and right sides of the drilling plate, and the control rod is slidably connected to the drilling plate through the through holes.

[0010] Preferably, in any of the above embodiments, two symmetrically arranged guide rods are fixedly connected to the side of the movable plate away from the card plate. The two guide rods are respectively located inside two springs, and both guide rods slide through the mounting plate and are slidably connected to the drilling plate.

[0011] Preferably, in any of the above solutions, the bottom surface of the pressure frame is fixedly connected with a number of symmetrically arranged pins, and the top surface of the drilling plate is provided with a number of symmetrically arranged insertion holes, with the pins inserted into the insertion holes respectively.

[0012] Preferably, in any of the above embodiments, a first magnet plate is embedded in the bottom surface of the pressure frame, and a second magnet plate is embedded in the top surface of the drilled plate, wherein the polarities of the corresponding ends of the first magnet plate and the second magnet plate are the same.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. When drilling circuit boards, the operator first needs to insert the circuit board body into the embedding groove, then remove the pressure frame and insert the pin into the insertion hole. At this time, continue to push the pressure frame in the direction of the pin's movement until the bottom surface of the locking frame contacts the top surface of the card plate. Because the top surface of the card plate is arc-shaped, the downward-moving pressure frame will press the card plate into the sliding groove until the bottom surface of the pressure frame is in contact with the top surface of the circuit board body. The card plate will then engage with the locking frame. The pressure of the pressure frame can lock the circuit board body into the embedding groove. It is not necessary to use tape to lock the four sides of the circuit board one by one, which can realize the rapid loading of circuit boards.

[0015] 2. After drilling is completed, the operator can simultaneously push the control rods on both sides of the drilling plate inward. This will cause the two moving plates to slide inside the slide groove, and simultaneously cause the two clamping plates to retract into the slide groove. Once the two clamping plates are disengaged from the two locking frames, the locking frames can be released. Under the repulsive force between the first and second magnetic plates, the pressure frame moves up and down, enabling rapid disassembly of the pressure frame. Finally, the circuit board body can be removed from the embedded slot. This allows for rapid unloading of the circuit board body without the need for a large amount of tape, saving material costs and greatly improving circuit board production efficiency.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0025] like Figures 1 to 7 As shown, a circuit board drilling machine for easy loading and unloading includes a chassis 1. A protective frame 2 is fixedly installed on the top surface of the chassis 1. Several drilling plates 3 are fixedly installed on the top surface of the chassis 1 by bolts. Two symmetrically arranged sliding grooves 4 are opened on the bottom surface of the drilling plates 3, and two symmetrically arranged locking grooves 5 are opened through the top surface of the drilling plates 3. The two sliding grooves 4 are located between the two locking grooves 5. An mounting plate 6 is fixedly installed on the inner wall of the sliding grooves 4 by bolts. Two symmetrically arranged springs 7 are fixedly connected to one side of the mounting plate 6. A movable plate 8 is fixedly connected to the end of the two springs 7 away from the mounting plate 6. The movable plate 8 is connected to the drilling plates 3 through the sliding grooves 4. A sliding connection is made, and a locking plate 9 is fixedly connected to the side of the moving plate 8 away from the spring 7. The top surface of the locking plate 9 is arc-shaped. The ends of the two locking plates 9 away from the moving plate 8 are respectively located inside the two locking slots 5. The inner wall of the locking slot 5 is slidably connected to two symmetrically arranged locking frames 10. The two locking plates 9 are respectively engaged with the two locking frames 10. The bottom surface of the drilling plate 3 is embedded with the circuit board body 11. The bottom end of the two locking frames 10 is fixedly connected to the pressure frame 12. The bottom surface of the pressure frame 12 is in contact with the top surface of the circuit board body 11. Control rods 13 are slidably connected to both the left and right sides of the drilling plate 3. The control rods 13 are fixedly connected to the moving plate 8.

[0026] As an optional technical solution of this utility model, the bottom surface of the drilling plate 3 is fixedly connected with a positioning pin 14, and the top surface of the chassis 1 is provided with a positioning hole 15. The positioning pin 14 is slidably connected to the chassis 1 through the positioning hole 15, and the drilling plate 3 is engaged with the chassis 1 through the positioning pin 14, which can make the connection between the two more stable.

[0027] As an optional technical solution of this utility model, the top surface of the drilling plate 3 is provided with an embedding groove 16. The circuit board body 11 is slidably connected to the drilling plate 3 through the embedding groove 16. The circuit board body 11 can be locked inside the embedding groove 16 by the squeezing of the pressure frame 12. It is not necessary to use tape to lock the four sides of the circuit board one by one, which can realize the rapid feeding of the circuit board.

[0028] As an optional technical solution of this utility model, through holes 17 are provided on both the left and right sides of the drilling plate 3. The control rod 13 is slidably connected to the drilling plate 3 through the through holes 17. At the same time, pushing the control rods 13 on the left and right sides of the drilling plate 3 inward can drive the two moving plates 8 to slide inside the slide groove 4, and can drive the two clamping plates 9 to retract into the slide groove 4 at the same time, so as to control the movement of the clamping plates 9.

[0029] As an optional technical solution of this utility model, two symmetrically arranged guide rods 18 are fixedly connected to the side of the movable plate 8 away from the card plate 9. The two guide rods 18 are located inside the two springs 7 respectively. Both guide rods 18 pass through the mounting plate 6 and are slidably connected to the drilling plate 3. The guide rods 18 can guide the movement of the movable plate 8.

[0030] As an optional technical solution of this utility model, the bottom surface of the pressure frame 12 is fixedly connected with a number of symmetrically arranged pins 19, and the top surface of the drilling plate 3 is provided with a number of symmetrically arranged insertion holes 20. The pins 19 are inserted into the insertion holes 20 respectively. The pressure frame 12 is taken out and the pins 19 are inserted into the insertion holes 20. At this time, the pressure frame 12 is pushed along the movement direction of the pins 19 to ensure that the locking frame 10 is aligned with the locking groove 5.

[0031] As an optional technical solution of this utility model, a first magnet plate 21 is embedded in the bottom surface of the pressure frame 12, and a second magnet plate 22 is embedded in the top surface of the drilled plate 3. The polarities of the corresponding ends of the first magnet plate 21 and the second magnet plate 22 are the same. Under the action of the repulsive force between the first magnet plate 21 and the second magnet plate 22, the pressure frame 12 is driven to move up and down, which can realize the quick disassembly of the pressure frame 12.

[0032] A circuit board drilling machine that facilitates loading and unloading, works on the following principle:

[0033] 1) When drilling a circuit board, the operator first needs to insert the circuit board body 11 into the embedded groove 16, then take out the pressure frame 12 and insert the pin 19 into the insertion hole 20. At this time, the pressure frame 12 is pushed along the movement direction of the pin 19.

[0034] 2): After the bottom surface of the locking frame 10 contacts the top surface of the card plate 9, the downward-moving pressure frame 12 will press the card plate 9 into the slide groove 4 because the top surface of the card plate 9 is arc-shaped. After the bottom surface of the pressure frame 12 is in contact with the top surface of the circuit board body 11, the card plate 9 will be engaged with the locking frame 10. The circuit board body 11 can be locked in the embedded groove 16 by the pressure of the pressure frame 12.

[0035] 3): Simultaneously push the control rods 13 on the left and right sides of the drilling plate 3 inward, which can drive the two moving plates 8 to slide inside the slide groove 4, and drive the two clamping plates 9 to retract into the slide groove 4 at the same time. After the two clamping plates 9 are separated from the two locking frames 10 respectively, the locking of the locking frame 10 can be released. Under the action of the repulsive force between the first magnet plate 21 and the second magnet plate 22, the pressure frame 12 is driven to move up and down, which can realize the quick disassembly of the pressure frame 12.

[0036] In summary, this circuit board drilling machine, which facilitates loading and unloading, requires the operator to first insert the circuit board body 11 into the embedding groove 16 during drilling operations. Then, the operator removes the pressure frame 12 and inserts the pin 19 into the insertion hole 20. The pressure frame 12 is then pushed along the direction of the pin 19 until the bottom surface of the locking frame 10 contacts the top surface of the clamping plate 9. Because the top surface of the clamping plate 9 is arc-shaped, the downward-moving pressure frame 12 presses the clamping plate 9 into the sliding groove 4 until the bottom surface of the pressure frame 12 is in contact with the top surface of the circuit board body 11. At this point, the clamping plate 9 engages with the locking frame 10. The pressure of the pressure frame 12 locks the circuit board body 11 into the embedding groove 16, eliminating the need to use tape to individually clean the four sides of the circuit board. Locking allows for rapid board loading. After drilling is complete, workers can simultaneously push the control levers 13 on both sides of the drilling plate 3 inward, causing the two moving plates 8 to slide inside the slide groove 4. This causes the two clamping plates 9 to retract into the slide groove 4 simultaneously. Once the two clamping plates 9 are disengaged from the two locking frames 10, the locking frames 10 can be released. Under the repulsive force between the first magnet plate 21 and the second magnet plate 22, the pressure frame 12 moves up and down, enabling rapid disassembly of the pressure frame 12. Finally, the circuit board body 11 can be removed from the embedded groove 16. This allows for rapid unloading of the circuit board body 11 without the need for a large amount of tape, saving material costs and greatly improving circuit board production efficiency.
