During the manufacturing process of a vehicle navigator, especially during circuit board assembly, precision drilling equipment is required to drill mounting holes or other functional holes on the circuit board for subsequent installation of other electronic components or connection devices. Therefore, a special precision drilling equipment for manufacturing vehicle navigators is needed.

Specific embodiments

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0033] Example 1, as Figure 1-2 shown, a precision drilling device for manufacturing a vehicle navigator includes a first support table 1, a first support group 2 is fixedly connected to the upper end of the first support table 1, a gear 3 is rotatably connected to the upper right side of the first support table 1, an auxiliary mechanism 5 is fixedly connected to the middle of the upper end of the first support table 1, a fixing mechanism 6 is provided between the lower side of the auxiliary mechanism 5 and the gear 3, a drilling component 4 is fixedly connected to the rear side of the upper end of the first support table 1, a motor 8 is fixedly connected to the rear part of the lower side of the first support group 2, a transmission wheel 7 is fixedly connected to the output end of the motor 8 and the upper end of the gear 3, and the two transmission wheels 7 are connected by a belt.

[0034] It should be noted that the specific installation method, circuit connection method and control method of the motor 8 in the present invention are all conventional designs, which are the conventional design means of designers. In addition, the drilling component 4 is composed of a main shaft, a chuck device, a drill bit, a motor, a lead screw, a sensor, a vertical guide column, a slide rod frame, a slide plate seat, a motor and a lead screw, etc., to realize the precise movement of the drill bit in the vertical direction, and drive the lead screw to rotate through the motor, so as to drive the slide plate seat to move in the horizontal direction, realize the precise adjustment of the drill bit in the horizontal direction, and the various structures cooperate with each other to finally realize the drilling operation of the drilling component 4 on the circuit board in the vehicle navigator.

[0035] First, with the cooperation of the first support group 2, the navigator circuit board to be drilled is transported to the rightmost side of the fixing mechanism 6, and the fixing mechanism 6 fixes the navigator circuit board transported to the rightmost side through the auxiliary mechanism 5. Then, the motor 8 is started to drive the transmission wheel 7 fixedly connected to the motor 8 to rotate. With the cooperation of the belt, the transmission wheel 7 drives the gear 3 to rotate. Through the rotation of the gear 3, the fixing mechanism 6 rotates counterclockwise by 90 degrees between the auxiliary mechanism 5 and the first support group 2, so that the navigator circuit board originally fixed on the rightmost side of the fixing mechanism 6 rotates to directly below the drilling component 4, and the drilling component 4 drills the navigator circuit board according to requirements. At the same time, with the cooperation of the first support group 2, the next navigator circuit board to be drilled is transported to the rightmost side of the fixing mechanism 6 at this moment and fixed through the cooperation of the auxiliary mechanism 5. When the drilling component 4 finishes drilling the navigator circuit board at the rearmost side of the fixing mechanism 6, the motor 8 is then started, and with the cooperation of the belt, the transmission wheel 7 and the gear 3, the fixing mechanism 6 rotates 90 degrees again, so that the navigator circuit board fixed on the rightmost side of the fixing mechanism 6 rotates to directly below the drilling component 4, and the navigator circuit board that has been drilled directly below the drilling component 4 will be rotated to the leftmost side by the fixing mechanism 6. At this moment, the drilling component 4 drills the navigator circuit board directly below. The next navigator circuit board to be drilled is transported to the rightmost side of the fixing mechanism 6 through the first support group 2 and fixed through the cooperation of the auxiliary mechanism 5. At the same time, the auxiliary mechanism 5 also acts on the rightmost side of the fixing mechanism 6 to release the fixing state of the navigator circuit board on the rightmost side. When the drilling component 4 finishes drilling the navigator circuit board directly below again, the fixing mechanism 6 is rotated 90 degrees again. The navigator circuit board in the released fixing state on the leftmost side of the fixing mechanism 6 is rotated to the frontmost side and transported outside the device through the cooperation of the first support group 2 to achieve automatic blanking. By operating in this cycle, not only the purpose of automatically loading and unloading the navigator circuit board during the drilling operation is achieved, but also the drilling efficiency is improved, and the drill chips generated during the drilling process are automatically discharged outside the device through the fixing mechanism 6 and the auxiliary mechanism 5.

[0036] To assist the fixing mechanism 6 in completing the automatic loading and unloading of the navigator circuit board and the automatic removal of drill chips, as Figure 3 shown, the auxiliary mechanism 5 includes a support disk 51. The lower end of the support disk 51 is fixedly connected to a discharge hopper 52. The middle part of the inner cavity of the support disk 51 is fixedly connected to a housing 58. The lower side of the inner cavity of the housing 58 is fixedly connected to a slide rail 54. The outer surface of the slide rail 54 is slidably connected to a driving component 53. The upper end of the driving component 53 is fixedly connected to a telescopic rod 57. The output end of the telescopic rod 57 is fixedly connected to an auxiliary group 56. The lower end of the support disk 51 is fixedly connected to the upper end of the first support platform 1. The middle part of the outer surface of the housing 58 is fixedly connected to an annular rail 55.

[0037] It should be noted that the specific installation method of the telescopic rod 57, the connection method of the circuit, and the control method in the present invention are all conventional designs, which are the conventional design means of designers. In addition, the driving component 53 is composed of components such as a driving motor, rollers, and a sliding housing sleeve. Through the cooperation of each component, the driving component 53 can move left and right on the slide rail 54.

[0038] First, the support disk 51 is installed on the upper end of the first support platform 1, and a through groove is provided in the middle of the upper end of the first support platform 1, which is adapted to the discharge hopper 52. The fixing mechanism 6 is installed on the upper side of the outer surface of the support disk 51 and can rotate. The outer shell 58 is installed in the middle of the inner cavity of the support disk 51 with a gap therebetween. The drill chips generated by drilling the navigation board fixed in the fixing mechanism 6 by the drilling component 4 will fall along the fixing mechanism 6 into the area between the inner cavity of the support disk 51 and the outer surface of the outer shell 58, and through the rotation of the fixing mechanism 6, the drill chips will finally enter the discharge hopper 52 through the gap between the outer shell 58 and the inner cavity of the support disk 51 and be discharged outside the device through the discharge hopper 52. When the navigation board is transported to the fixing mechanism 6 by the first support group 2, the telescopic rod 57 drives the auxiliary group 56 to descend to an appropriate height, so that the left side of the auxiliary group 56 is stuck on the side where the navigation board has not entered the fixing mechanism 6. Then, the driving component 53 drives the telescopic rod 57 to move to the right on the outer surface of the slide rail 54, so that the auxiliary group 56 drags the navigation board to completely enter the appropriate position on the far left side of the fixing mechanism 6. If there is a drilled navigation board fixed on the far right side of the fixing mechanism 6 at this moment, while the auxiliary group 56 moves to the right, the navigation board on the far right side of the fixing mechanism 6 will be released from the fixed state by the right side of the auxiliary group 56. After the navigation board enters the appropriate position, the telescopic rod 57 then drives the auxiliary group 56 to move downward, so that the auxiliary group 56 acts on the left side of the fixing mechanism 6, and the fixing mechanism 6 clamps and fixes the navigation board on the left side. During the rotation of the fixing mechanism 6, the middle of the fixing mechanism 6 fits on the outer surface of the circular rail 55 away from the outer shell 58 and rotates, and the automatic loading and unloading of the navigation board is completed, ultimately achieving the purpose of assisting the fixing mechanism 6 to complete the automatic loading and unloading of the navigation board and the automatic removal of drill chips.

[0039] Further explanation, as Figure 4 shown, the auxiliary group 56 includes a round block 561. A clamping cover 562 is fixedly connected to the left side of the outer surface of the round block 561, and an L-shaped push handle 563 is fixedly connected to the rear side of the outer surface of the round block 561. The lower end of the round block 561 is fixedly connected to the output end of the telescopic rod 57.

[0040] Specifically, through the combined use of the telescopic rod 57, the slide rail 54, and the driving component 53, the round block 561 drives the cover 562 and the L-shaped push handle 563 to move together, enabling the cover 562 to act on the leftmost side of the fixing mechanism 6 and the L-shaped push handle 563 to act on the rightmost side of the fixing mechanism 6. Moreover, the front part of the right side of the outer surface of the L-shaped push handle 563 is curved, and the mutually approaching surfaces on the left and right sides of the lower end of the cover 562 are also curved, which cooperate with the fixing mechanism 6.

[0041] The auxiliary mechanism 5 and the fixing mechanism 6 cooperate to complete the automatic loading and unloading operation of the navigator circuit board, as Figure 5 shown. The first support group 2 includes a second support platform 21. In the middle of the upper end of the second support platform 21, there is a sleeve column 24. Together with the sleeve column 24, a first conveying component 22 is provided in the middle of the front side of the upper end of the second support platform 21. Together with the sleeve column 24, a second conveying component 23 is provided in the middle of the right side of the upper end of the second support platform 21. The lower end of the second support platform 21 is fixedly connected to the upper end of the first support platform 1.

[0042] It should be noted that both the first conveying component 22 and the second conveying component 23 are composed of a mounting frame, a rotating shaft, a conveyor belt, and a small driving motor. Each structure cooperates with each other, enabling the second conveying component 23 to transport the un-drilled navigator circuit board to the fixing mechanism 6, and enabling the first conveying component 22 to transport the drilled navigator circuit board outside the device. By adding the sleeve column 24, not only is the fixing mechanism 6 more stable during rotation, but to a certain extent, it also prevents the drill chips from scattering outside the device during the process of falling from the fixing mechanism 6. The drill chips can be uniformly discharged outside the device through the discharge hopper 52, ensuring the cleanliness of the site, achieving the purpose of cooperating with the auxiliary mechanism 5 and the fixing mechanism 6 to complete the automatic loading and unloading of the navigator circuit board.

[0043] Embodiment 2. On the basis of Embodiment 1, this embodiment completes the clamping and fixing of the navigator circuit board, as Figure 6 and Figure 7 shown. The fixing mechanism 6 includes a rotating ring seat 62 rotatably connected to the upper part of the outer surface of the support disk 51. A gear ring 61 is fixedly connected to the outer surface of the rotating ring seat 62. Four rotating seats 63 are fixedly connected to the upper end of the rotating ring seat 62 in an annular array. Four guard plates 64 are fixedly connected to the inner cavity of the rotating ring seat 62 in an annular array. A second support group 66 is fixedly connected to the inner cavity of the rotating ring seat 62. A fixing group 65 is rotatably connected to the inner cavity of each of the four rotating seats 63. The middle parts of the outer surfaces of the four fixing groups 65 are jointly attached to the outer body of the ring rail 55. The lower ends of the four guard plates 64 are jointly attached to the bottom wall of the inner cavity of the support disk 51. The upper part of the outer surface of the rotating ring seat 62 is rotatably connected to the lower part of the inner cavity of the sleeve column 24.

[0044] First, a groove adapted to the upper side of the outer surface of the support disk 51 is provided at the lower end of the rotating ring base 62. The rotation of the gear 3 causes the gear ring 61 to drive the rotating ring base 62 to rotate on the upper side of the outer surface of the support disk 51 and the lower side of the inner cavity of the sleeve column 24. Through the rotation of the rotating ring base 62, the four fixed groups 65 arranged in an annular array will rotate together under the combined use of the rotating seat 63 and the second support group 66. Each rotation is 90 degrees. The un-drilled navigator circuit board is transported by the second conveying member 23 to the right fixed group 65, and under the combined use of the driving member 53, the slide rail 54, the telescopic rod 57 and the auxiliary group 56, the fixed group 65 on the right fixes the navigator circuit board. Through the rotation of the rotating ring base 62, it rotates to directly below the drilling member 4, and the drilling operation is carried out by the drilling member 4. Then it continues to rotate. When it reaches the right side, the fixed state is released through the cooperation of the telescopic rod 57. When it rotates to the front side, under the combined use of the ring rail 55, the fixed group 65 rotates at a certain angle in the inner cavity of the rotating seat 63 and on the second support group 66. The navigator circuit board in the released fixed state slides obliquely along the upper side of the fixed group 65 onto the first conveying member 22 and is transported out of the device. By operating in this cycle, the automatic feeding and fixing of the navigator circuit board are realized, as well as the operation of automatically discharging the fixed state after drilling is completed, reducing the working time and improving the working efficiency. When the drilling member 4 drills the navigator circuit board, the drill chips generated fall from the upper side of the fixed group 65 into the area between the inner cavity of the support disk 51 and the outer surface of the housing 58. The guard plate 64 is provided with a groove, and the lower side of the outer surface of the curved rod 651 is sleeved inside the groove provided in 64. By installing the guard plate 64, not only the stability of the rotation of the fixed group 65 in the inner cavity of the rotating seat 63 and on the second support group 66 is enhanced, but also the curved surface inclined on the lower side of the outer surface of the guard plate 64 can push the drill chips on the bottom wall of the inner cavity of the rotating ring base 62 into the inner cavity of the discharge hopper 52 during the rotation of the rotating ring base 62, and finally discharged out of the device, without manual cleaning, saving time and effort.

[0045] Further explanation, as Figure 8 shown, the second support group 66 includes a ring plate 662. Four support rods 661 are fixedly connected in an annular array at the lower end of the ring plate 662. The ends of the four support rods 661 away from the ring plate 662 are commonly fixedly connected to the inner cavity of the rotating ring base 62. Four rotating frames 663 are fixedly connected in an annular array at the upper end of the ring plate 662.

[0046] By installing the rotating frames 663, the upper side of the fixed group 65 can rotate at a certain angle in the vertical direction on the outer surface of the rotating frames 663. The support rods 661 and the ring plate 662 support the rotating frames 663, enhancing the stability of the rotation of the fixed group 65 in the horizontal direction and the rotation in the vertical direction.

[0047] Further explanation, as Figure 9 and Figure 10As shown, the four fixed groups 65 all include curved rods 651. The lower sides of the outer surfaces of the four support disks 51 are respectively rotatably connected to the inner cavities of the four rotating seats 63. Slide rods 652 are fixedly connected to the upper sides of the outer surfaces of the four curved rods 651. Fixed frames 653 are slidably connected to the outer surfaces of the four cover caps 562. The upper ends of the four fixed frames 653 are fixedly connected to inclined groove plates 655. Locking groups 654 are fixedly connected to the upper ends of the four inclined groove plates 655. Rotating grooves 656 are formed on one side of the outer surfaces of the four inclined groove plates 655 away from each other. The outer surfaces of the four rotating grooves 656 are respectively rotatably connected to one side of the outer surfaces of the four rotating frames 663 away from each other.

[0048] Specifically, the curved rod 651 is installed in the inner cavity of the rotating seat 63 and can rotate. The inclined groove plate 655 is installed on the outer surface of the rotating frame 663 through the rotating groove 656, so that the inclined groove plate 655 can rotate on the outer surface of the rotating frame 663. The middle part of the outer surface of the circular track 55 is semicircular backward, while the middle part forward is higher in the front than on the left and right sides. When the rotating ring seat 62 rotates, through the cooperation of the rotating seat 63 and the second support group 66, the fixed group 65 rotates together. The curved rod 651 rotates while fitting on the outer surface of the circular track 55. When the curved rod 651 rotates from the right side to the front side, the curved rod 651 tilts upward along the circular track 55 and rotates upward in the inner cavity of the rotating seat 63. At the same time, the curved rod 651 pushes the slide rod 652 to slide forward in the inner cavity of the fixed frame 653, so that the fixed frame 653 pushes the inclined groove plate 655 to rotate on the outer surface of the rotating frame 663 with the rotating groove 656 as the center. When the entire fixed group 65 rotates to the most front side, the inclined groove plate 655 rotates forward to an appropriate height, and the navigator circuit board drilled between the locking group 654 and the inclined groove plate 655 slides down onto the first conveying component 22 under the action of gravity and is transported to the outside of the device by the first conveying component 22. When the rotating ring seat 62 drives the fixed group 65 to rotate 90 degrees from the front side to the left side, the curved rod 651 rotates downward along the surface of the circular track 55 and in the inner cavity of the rotating seat 63. When reaching the left side, the inclined groove plate 655 returns to the initial state and is parallel to the rotating frame 663. In addition, inclined grooves are formed in the middle parts of the upper ends of the four inclined groove plates 655, and the inclined grooves incline toward the side away from the rotating groove 656. When the drilling component 4 drills the navigator circuit board clamped between the locking group 654 and the inclined groove plate 655, the drill chips will slide down along the inclined grooves to the area between the support disk 51 and the housing 58.

[0049] In order to achieve the clamping and fixing of the navigator circuit board, as Figure 11 and 12As shown in the figure, each of the four latch groups 654 includes a U-shaped frame 6541. On the bottom wall of the inner cavity on the side where the four U-shaped frames 6541 are close to each other, four second springs 6546 are fixedly connected. The upper ends of the four second springs 6546 on the same side are jointly fixedly connected to a U-shaped pressing plate 6542. On the side where the upper ends of the four second springs 6546 are close to each other, four chutes 6547 are opened. On the side of the inner cavity of the four chutes 6547 on the same side away from the second springs 6546, through grooves 6549 are opened. And a slider 6548 is slidably connected to the inner cavity of the four chutes 6547 on the same side and the inner cavity of the through grooves 6549. The ends of the four sliders 6548 on the same side away from the U-shaped pressing plate 6542 are jointly fixedly connected to an arc-angle push rod 6545. The ends of the four sliders 6548 on the same side away from the arc-angle push rod 6545 are fixedly connected to third springs 65491 respectively. The ends of the four third springs 65491 on the same side away from the sliders 6548 are fixedly connected to the inner cavities of the four chutes 6547 respectively. A limit pin 6544 is provided on the outer surface of the four chutes 6547 on the same side and the outer surface of the four sliders 6548. On one side of the outer surface of the limit pin 6544 on the same side, a first spring 6543 is fixedly connected. The end of the first spring 6543 on the same side away from the limit pin 6544 is fixedly connected to the inner cavity of the U-shaped frame 6541. The outer surfaces of the four arc-angle push rods 6545 on the side away from each other are slidably connected to the inner cavities of the four U-shaped frames 6541 respectively. The outer surfaces of the four limit pins 6544 are slidably connected to the inner cavities of the four U-shaped frames 6541 respectively. The sides of the four U-shaped pressing plates 6542 on the outer surface close to each other are slidably connected to the inner cavities of the U-shaped frames 6541 respectively. The lower ends of the four U-shaped frames 6541 are fixedly connected to the upper ends of the four inclined groove plates 655 respectively.

[0050] In the initial state, the latch group 654 located on the left side is in a relaxed state. The navigator circuit board is transported by the second transport component 23 to between the latch group 654 and the chute plate 655. When the navigator circuit board is transported to the leftmost side of the second transport component 23 and detaches from the outer surface of the second transport component 23, the second transport component 23 cannot act on the navigator circuit board, and the navigator circuit board cannot be completely transported to the appropriate position between the latch group 654 and the chute plate 655. At this time, it is necessary to start the telescopic rod 57 to drive the auxiliary group 56 to descend to an appropriate height, so that the left side of the lower end of the cover 562 is stuck on the side of the navigator circuit board that has not entered the chute plate 655. Then, the driving component 53 drives the telescopic rod 57 to move to the right on the outer surface of the slide rail 54. With the cooperation of the round block 561, the cover 562 further drags the navigator circuit board to completely enter the appropriate position between the latch group 654 and the chute plate 655. Then, the telescopic rod 57 drives the cover 562 to move downward through the round block 561, so that the right side of the lower end of the cover 562 moves downward and pushes the arc angle push rod 6545. The arc angle push rod 6545 pushes the slider 6548 to slide in the inner cavity of the chute 6547 and compresses the third spring 65491, so that the slider 6548 no longer blocks the limit pin 6544. Under the elastic force of the first spring 6543, the limit pin 6544 is pushed out of the inner cavity of the chute 6547. And under the elastic force of the third spring 65491, the slider 6548 and the second spring 6546 return to the initial state. The limit pin 6544 pushes the U-shaped pressing plate 6542 to slide downward in the inner cavity of the U-shaped frame 6541 and compresses the second spring 6546, so that the U-shaped pressing plate 6542 presses the navigator circuit board for fixation. At the same time, the cover 562 is driven to move to the right through the round block 561, and the L push handle 563 will also move, acting on the latch group 654 on the right side, so that the right side of the outer surface of the L push handle 563 pushes the limit pin 6544, so that the limit pin 6544 slides into the inner cavity of the U-shaped frame 6541 and compresses the first spring 6543. The limit pin 6544 returns to the inner cavity of the chute 6547 again. Under the elastic force of the second spring 6546, the U-shaped pressing plate 6542 moves upward and no longer presses the navigator circuit board tightly. The navigator circuit board is released from the fixed state. Finally, the driving component 53 cooperates with the telescopic rod 57 to make the auxiliary group 56 return to the initial state and wait for the next operation, and finally achieves the purpose of clamping and fixing the navigator circuit board and releasing the fixation after drilling.
