Description

Technical Field

[0001] This utility model relates to the field of PCB drill bit processing technology, and in particular to a multi-station PCB drill bit processing device. Background Technology

[0002] In the production and processing of PCB drill bits, efficient and precise processing equipment is crucial. With the rapid development of the electronics industry, the demand for PCB drill bits is constantly increasing in both quantity and quality. Traditional PCB drill bit processing equipment often has many problems.

[0003] Existing technologies have the following problems:

[0004] On the one hand, most processing equipment is designed as a single or dual-station unit, capable of processing only one or a few drill bit blanks at a time. This results in low production efficiency and makes it difficult to meet the demands of large-scale production. In today's rapidly evolving electronic product landscape, slow-paced production means companies need to invest more time and resources to fulfill order requirements, weakening their market competitiveness. On the other hand, existing equipment has poor adaptability when clamping and fixing drill bit blanks of different specifications. Due to the diverse diameters, lengths, and other specifications of drill bit blanks, traditional clamping methods are usually only suitable for fixing blanks of specific specifications. For blanks of other specifications, they either cannot be fixed or the fixing effect is poor, leading to easy shaking or displacement of the blank during processing. This seriously affects processing accuracy, and insufficient processing accuracy can cause drilling deviations and non-compliant hole diameters in the produced PCB drill bits during subsequent use, thus affecting the PC... In addition to the quality and performance of the B-board, existing technologies also have shortcomings in the maintenance of processing equipment. For example, anti-slip components used to increase the friction between the blank and the clamping device are often difficult to disassemble and replace. Once the anti-slip components are worn, not only will the stability of the clamping be reduced, but the replacement process will also be cumbersome, requiring a lot of time and manpower, affecting the continuity of production. At present, although there are some improved processing equipment, they still cannot fully solve the above problems. For example, although some multi-station processing equipment increases the number of processing stations, there is no substantial breakthrough in the universality of blank clamping and the ease of maintenance of anti-slip components. Some devices that can clamp blanks of different specifications have problems such as complex structure and high cost, making it difficult to be widely used in actual production. Therefore, it is urgent to develop a PCB drill bit processing equipment that can simultaneously solve the problems of multi-station processing, clamping and fixing blanks of different specifications, and easy maintenance of components.

[0005] To address these shortcomings, we proposed a multi-station PCB drilling device. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-station PCB drill bit processing device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station PCB drill bit processing device, including a base, a column welded to one end of the top surface of the base, a top plate fixedly installed at the top of the column, a servo electric cylinder fixedly installed on the top surface of the top plate, a bracket installed at the telescopic end of the servo electric cylinder, and multiple cutting machines installed on the bracket, a bearing plate fixedly connected to the column, a servo motor fixedly installed on the bottom surface of the bearing plate, a positive and negative threaded screw installed at the output end of the servo motor, and threaded blocks used in conjunction with the surfaces of the positive and negative threaded screws, a guide groove opened on the surface of the bearing plate, a guide rod slidably connected inside the guide groove, one end of the guide rod fixedly connected to the top surface of the threaded block, a clamping block fixedly installed at the other end of the guide rod, a hook and loop fastener surface adhered to the inner wall of the clamping block, a hook and loop fastener rough surface adhered to the hook and loop fastener surface, and an anti-slip pad adhered to the side of the hook and loop fastener surface away from the hook and loop fastener surface.

[0008] Preferably, a control switch is fixedly installed on the column, and the control switch is electrically connected to the servo cylinder, servo motor and cutting machine through wires.

[0009] Preferably, the surface area of ​​the anti-slip pad is the same as the surface area of ​​the clamping block.

[0010] Preferably, the length of the guide groove is less than the length of the forward and reverse threaded screws.

[0011] Preferably, the length of the guide rod is greater than the depth of the guide groove.

[0012] Preferably, multiple guide grooves and positive and negative threaded screws are provided, and multiple guide grooves and positive and negative threaded screws are equidistantly distributed on the surface of the bearing plate.

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

[0014] 1. In this utility model, the bearing plate is provided with several positive and negative threaded screws. Each positive and negative threaded screw can correspond to a drill bit blank to be cut, and multiple drill bit blanks can be cut at the same time. Compared with traditional single-station or double-station processing devices, it greatly improves production efficiency and meets the needs of large-scale production. The positive and negative threaded screws are driven to rotate by a servo motor, which can cause the threaded block to drive the clamping block to move in opposite directions or in opposite directions, so as to clamp and fix drill bit blanks of different specifications. Whether the blank has a large diameter or a small diameter, a suitable clamping position can be found, ensuring the stability and accuracy of the blank during the processing.

[0015] 2. In this utility model, the anti-slip mat is fixed by Velcro. When the anti-slip mat is worn and needs to be replaced, simply tear off the Velcro to easily remove the old anti-slip mat and replace it with a new one. The operation is simple and convenient, saving maintenance time and labor costs, and helping to ensure the continuity of production. Attached Figure Description

[0024] Please refer to Figure 1-3 A multi-station PCB drilling device includes a base 1, a column 2 welded to one end of the top surface of the base 1, a top plate 3 fixedly mounted on the top of the column 2, a servo cylinder 4 fixedly mounted on the top surface of the top plate 3, a bracket 5 mounted on the telescopic end of the servo cylinder 4, and multiple cutting machines 6 mounted on the bracket 5. A bearing plate 8 is fixedly connected to the column 2, and a servo motor 9 is fixedly mounted on the bottom surface of the bearing plate 8. A positive and negative thread screw 10 is mounted on the output end of the servo motor 9. The surface is fitted with a threaded block 11, and the surface of the bearing plate 8 is provided with a guide groove 12. A guide rod 13 is slidably connected inside the guide groove 12. One end of the guide rod 13 is fixedly connected to the top surface of the threaded block 11, and the other end of the guide rod 13 is fixedly installed with a clamping block 14. A hook and loop fastener 15 is adhered to the inner wall of the clamping block 14. A hook and loop fastener 16 is adhered to the hook and loop fastener 15, and an anti-slip pad 17 is adhered to the side of the hook and loop fastener 16 away from the hook and loop fastener 15.

[0025] According to the specifications of the drill bit blank to be cut, the servo motor 9 at the corresponding position on the support plate 8 is started. The servo motor 9 drives the forward and reverse threaded screws 10 to rotate. Since the threaded block 11 on the forward and reverse threaded screws 10 is slidably connected to the guide rod 13, and the guide rod 13 is installed in the guide groove 12, the threaded block 11 will move in opposite directions or backward along the guide rod 13 under the drive of the forward and reverse threaded screws 10. When the threaded block 11 moves to the appropriate position, the drill bit blank is placed between the two clamping blocks 14. The servo motor 9 is adjusted to make the clamping blocks 14 tightly clamp the blank. The anti-slip pad 17 on the clamping surface of the clamping block 14 is fixed by the hook and loop fastener 15 and the rough hook and loop fastener 16. Its surface has a certain roughness, which can increase the friction between the pad and the blank and prevent the blank from slipping during processing. After the blank is slid and clamped, start the servo cylinder 4. The servo cylinder 4 pushes the bracket 5 downward, so that the cutting machine 6 mounted on the bracket 5 is close to the drill bit blank. According to the processing requirements, adjust the cutting parameters of the cutting machine 6, such as cutting speed and cutting depth, and then start the cutting machine 6 to cut the blank. During the cutting process, observe the cutting situation closely to ensure the accuracy and stability of the cutting. When the anti-slip pad 17 is worn and affects the clamping effect, turn off the power of the equipment, tear off the connection between the hook side 15 and the hook side 16 of the Velcro, remove the worn anti-slip pad 17, clean the hook side 15 of the clamping block 14 to ensure that its surface is clean and free of debris, and then attach the new anti-slip pad 17 to the clamping block 14 with Velcro to complete the replacement of the anti-slip pad 17.

[0026] In this implementation plan: a control switch 7 is fixedly installed on the column 2, and the control switch 7 is electrically connected to the servo cylinder 4, the servo motor 9 and the cutting machine 6 through wires.

[0027] Specifically, during the preparation for processing, the operator first presses the button corresponding to the servo motor 9 to start the servo motor 9. According to the specifications of the drill bit blank to be processed, the operator adjusts the rotation direction and speed of the servo motor 9, thereby controlling the rotation of the positive and negative thread screws 10 to adjust the position of the clamping block 14 to clamp the blank. After the blank is clamped, the operator presses the button corresponding to the cutting machine 6 to set the cutting parameters, such as cutting speed and cutting depth. These parameters are preset on the cutting machine 6 according to the material and target size of the drill bit blank. The operator starts the cutting machine 6. When it is necessary to adjust the cutting position, the operator operates the servo cylinder 4 through the control switch 7 and presses the corresponding button to extend and retract the servo cylinder 4, driving the bracket 5 and the cutting machine 6 mounted on it to move up and down to achieve the appropriate cutting height.

[0028] In this embodiment, the surface area of ​​the anti-slip pad 17 is the same as the surface area of ​​the clamping block 14.

[0029] Specifically, this design allows the anti-slip pad 17 to completely cover the surface of the clamping block 14 that contacts the drill bit blank, ensuring that the friction between the blank and the clamping block 14 is evenly distributed when clamping the blank. Whether cutting small or large drill bit blanks, the blank and the anti-slip pad 17 can make full contact. For example, when processing drill bit blanks with a small diameter, because the anti-slip pad 17 completely covers the clamping surface of the clamping block 14, even if the contact area between the blank and the clamping block 14 is small, the anti-slip pad 17 can provide sufficient friction to stabilize the blank. When processing drill bit blanks with a large diameter, it can also ensure a good anti-slip effect on the entire contact surface, preventing the blank from shifting or shaking during the cutting process.

[0030] In this implementation scheme: the length of the guide groove 12 is less than the length of the positive and negative threaded screw 10.

[0031] Specifically, the length of the guide groove 12 is designed to provide sufficient travel space for the rotation of the positive and negative threaded screws 10 while ensuring the stable movement of the threaded block 11. The guide groove 12 restricts the threaded block 11 to move only in a specific direction to prevent it from deviating during movement. The positive and negative threaded screws 10 are longer, allowing the threaded block 11 to move within a wider range to meet the clamping requirements of drill bit blanks of different lengths. For example, for shorter blanks, the threaded block 11 can achieve clamping by moving a small distance within the guide groove 12. For longer blanks, the threaded block 11 can move to a suitable position over the longer travel of the positive and negative threaded screws 10, ensuring that blanks of different lengths can be accurately clamped.

[0032] In this embodiment, the length of the guide rod 13 is greater than the depth of the guide groove 12.

[0033] Specifically, when the guide rod 13 slides within the guide groove 12, a sufficient portion extends out of the guide groove 12 to connect with the threaded block 11 and the clamping block 14, ensuring the stability of the connection. When the servo motor 9 drives the forward and reverse threaded screws 10 to rotate, causing the threaded block 11 to move, the guide rod 13 can slide smoothly within the guide groove 12. Furthermore, because its length is greater than the depth of the guide groove 12, the connection between the guide rod 13 and the threaded block 11 and the clamping block 14 will not disengage from the guide groove 12 during the entire movement process. This effectively prevents the threaded block 11 and the clamping block 14 from shaking or tilting during movement, ensuring that the clamping block 14 can accurately clamp and position the drill bit blank.

[0034] In this embodiment, multiple guide grooves 12 and positive and negative threaded screws 10 are provided, and multiple guide grooves 12 and positive and negative threaded screws 10 are equidistantly distributed on the surface of the bearing plate 8.

[0035] Specifically, multiple equidistant guide grooves 12 and positive and negative threaded screws 10 allow multiple drill bit blanks of different specifications to be placed on the support plate 8 for processing simultaneously. The equidistant distribution ensures consistent spacing between each processing station, facilitating operation and management. For example, when mass-producing drill bits of different specifications, they can be placed reasonably on the corresponding clamping stations according to the diameter and length of the blanks. During processing, the operator can control the servo motor 9 and the cutting machine 6 at each station through the control switch 7, enabling simultaneous processing of multiple blanks and improving production efficiency. At the same time, the equidistant distribution also facilitates subsequent maintenance and repair of the equipment, making it easy to quickly locate the position of each component.

[0036] Working principle: According to the specifications of the drill bit blank to be cut, the servo motor 9 at the corresponding position on the bearing plate 8 is started. The servo motor 9 drives the forward and reverse threaded screws 10 to rotate. Since the threaded block 11 on the forward and reverse threaded screws 10 is slidably connected to the guide rod 13, and the guide rod 13 is installed in the guide groove 12, the threaded block 11 will move in opposite directions along the guide rod 13 under the drive of the forward and reverse threaded screws 10. When the threaded block 11 moves to the appropriate position, the drill bit blank is placed between the two clamping blocks 14. The servo motor 9 is adjusted to make the clamping blocks 14 tightly clamp the blank. The anti-slip pad 17 on the clamping surface of the clamping block 14 is fixed by the hook and loop fastener 15 and the rough hook and loop fastener 16. Its surface has a certain roughness, which can increase the friction between the pad and the blank and prevent the blank from slipping during processing. During the process, after the blank is clamped, the servo cylinder 4 is activated, which pushes the bracket 5 downward, bringing the cutting machine 6 mounted on the bracket 5 closer to the drill bit blank. According to the processing requirements, the cutting parameters of the cutting machine 6, such as cutting speed and cutting depth, are adjusted. Then, the cutting machine 6 is started to cut the blank. During the cutting process, the cutting situation should be closely observed to ensure the accuracy and stability of the cutting. When the anti-slip pad 17 is worn and affects the clamping effect, the power of the equipment is turned off, the connection between the hook and loop fastener 15 and the rough hook and loop fastener 16 is torn off, the worn anti-slip pad 17 is removed, the hook and loop fastener 15 on the clamping block 14 is cleaned to ensure that its surface is clean and free of debris, and then the new anti-slip pad 17 is attached to the clamping block 14 with hook and loop fastener to complete the replacement of the anti-slip pad 17.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
