Description

Technical Field

[0001] This utility model relates to the technical field of PCB precision drilling auxiliary equipment, and in particular to a drill cutter head transfer vehicle. Background Technology

[0002] In precision drilling operations on PCBs, six-axis CNC drilling machines employ 14 columns × 11 rows of cutter heads. Each cutter bar (cutter row) on the cutter head accommodates 11 drill bits, and each drill spindle is equipped with two cutter heads, requiring a total of 12 cutter heads for the six spindles. After processing, the cutter heads need to be removed and transported to the grinding room for processing. Currently, the industry mainstream uses multi-layer trolleys for transportation, but this method has many problems.

[0003] The existing multi-layer trolleys pose a high risk of workplace injury. The drill bit cutting edge is directly exposed upwards, making it easy for operators to have their gloves pierced and their palms pricked by the needle tip during handling or when the vehicle shakes. The side panels of the trolley are made of opaque PVC material and lack a structure that clearly displays the cutter head information. The cutter head must be removed to check the machine tool, axis number, and other information, which is inefficient and creates an information black hole. To prevent needle tip collisions, the distance between cutter heads needs to be ≥20cm. However, currently, each layer of the trolley is placed in parallel, and the need to maintain spacing results in a small number of cutter heads that can be stored on each layer, leading to low space utilization.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] like Figure 1 - Figure 4 As shown, this application provides a drilling rig cutterhead 20 transfer vehicle, which includes: The main body 10 of the transfer vehicle includes a bottom plate 11 at the bottom and a connecting plate 12 connected to the bottom plate 11 and arranged in a vertical direction. A plurality of sleeves 13 are connected at intervals on the connecting plate 12. One end of the sleeve 13 is fixedly connected to the connecting plate 12, and the other end is open. The sleeve 13 is made of transparent material. The bottom of the transfer cabinet is connected to rollers 15. Multiple cutter heads 20, each cutter head 20 being detachably connected to a sleeve 13.

[0022] The transfer cabinet consists of a base plate 11 at the bottom and a connecting plate 12 connected to the base plate 11, with the connecting plate 12 arranged vertically. Multiple sleeves 13 are spaced apart on the connecting plate 12; one end of each sleeve 13 is fixedly connected to the connecting plate 12, and the other end is open for inserting a cutter head 20. Rollers 15 are connected to the bottom of the transfer cabinet for easy movement of the transfer cart. Multiple cutter heads 20 correspond one-to-one with each sleeve 13, and each cutter head 20 can be detachably connected to the sleeve 13, allowing for independent storage of the cutter heads 20.

[0023] The base plate 11 is made of high-strength steel plate to ensure the load-bearing capacity of the transfer vehicle; the connecting plate 12 is also made of steel plate and is vertically welded to the center line of the base plate 11. Multiple sleeves 13 are fixed to both sides of the connecting plate 12 by bolts.

[0024] Furthermore, the sleeve 13 is made of acrylic.

[0025] Acrylic material has high transparency, which not only allows operators to visually view the drill bit and related information inside the cutter head 20, but also makes it sturdy enough to withstand the weight of the cutter head 20 and the internal drill bit, preventing damage and deformation and ensuring the long-term stability of the sleeve 13. At the same time, the smooth surface of acrylic material effectively reduces friction between the sleeve 13 and the cutter head 20 during insertion and removal, simplifying operation and preventing wear caused by friction, thus extending the service life of both the sleeve 13 and the cutter head 20.

[0026] Furthermore, the sleeve 13 has a rectangular cross-sectional shape.

[0027] Compared to other shapes, the rectangular cross-section design better fits the shape of the cutter head 20, allowing it to be placed more stably within the sleeve 13, reducing displacement caused by shaking during transport and lowering the risk of collision damage. Furthermore, the rectangular cross-section is more efficient in space utilization; multiple sleeves 13 can be arranged more compactly within the limited space of the connecting plate 12, thereby improving the space utilization of the transport vehicle and increasing the number of cutter heads 20 that can be accommodated.

[0028] Furthermore, the connecting plate 12 is connected to the center line of the base plate 11, and multiple sleeves 13 are connected to both sides of the connecting plate 12.

[0029] By placing the connecting plate 12 on the center line of the base plate 11, the overall center of gravity of the transfer vehicle is more evenly distributed, making it more stable during movement and less prone to dangerous situations such as tipping over. Sleeves 13 are connected to both sides of the connecting plate 12, making full use of the space of the connecting plate 12. With the same area of ​​the base plate 11, more cutter heads 20 can be placed, further increasing the load capacity of the transfer vehicle.

[0030] Furthermore, the plurality of sleeves 13 on each surface of the connecting plate 12 are arranged in a 4-column × 6-row matrix.

[0031] This matrix-partitioned layout has significant advantages. From a management perspective, partitioning allows for clearer classification and storage of the cutter heads 20, such as by different machine tools, axis numbers, or processing batches. This makes it easier for operators to quickly locate the required cutter heads 20, improving work efficiency. From a space utilization perspective, the matrix-partitioned layout allows for a more orderly arrangement of the sleeves 13, reducing gaps between them and maximizing the use of the space in the connecting plate 12, thus maximizing the storage capacity of the cutter heads 20. The sleeves 13 on each side of the connecting plate 12 are arranged in a 4-column × 6-row matrix partition, with 24 sleeves 13 on each side, totaling 48 sleeves 13 on both sides, which can store 48 cutter heads 20.

[0032] Furthermore, the cutter head 20 includes a support plate 21 located at the bottom, a cover plate 22 connected to one side of the support plate 21, and a handle 23 connected to the cover plate 22. The support plate 21 is used to place the cutter bar and the drill bit. When the cutter head 20 is placed in the sleeve 13, the support plate 21 is inserted into the sleeve 13, and the cover plate 22 is correspondingly closed to the opening of the sleeve 13.

[0033] The support plate 21 provides a stable platform for the cutter head and drill bits, ensuring that the drill bits do not wobble during transport and are not damaged by collisions. The cover plate 22 provides dual protection. On the one hand, by covering the opening of the sleeve 13, it prevents dust and debris from entering the sleeve 13 and contaminating the cutter head 20 and drill bits. On the other hand, the cover plate 22 can serve as an identification area, displaying relevant information about the cutter head 20, such as the machine number and axis number, for easy identification by operators. The handle 23 facilitates the operator's handling and placement of the cutter head 20, improving operational convenience. The cover plate 22 is connected to one side of the support plate 21 via a hinge. The size of the cover plate 22 is larger than the opening size of the sleeve 13, ensuring that it completely covers the opening of the sleeve 13 when closed. The handle 23 is welded to the outer surface of the cover plate 22 and has a U-shaped structure for easy gripping.

[0034] Furthermore, the inner side of the sleeve 13 is recessed with a horizontal groove 131, and the edge of the support plate 21 is provided with a slider 211. When the cutter head 20 is placed inside the sleeve 13, the slider 211 is correspondingly inserted into the groove 131. The cooperative design of the groove 131 and the slider 211 makes the insertion and removal of the cutter head 20 into the sleeve 13 smoother, reducing the occurrence of jamming. At the same time, this cooperative method can ensure that the position of the cutter head 20 inside the sleeve 13 is accurate and will not be offset, thus ensuring the stability of the cutter head 20 during transportation. Moreover, the structure of the groove 131 and the slider 211 is simple, easy to manufacture and maintain, and reduces production costs.

[0035] Furthermore, the bottom of the support plate 21 is connected to a plurality of placement blocks 212, which respectively abut against the bottom and bottom corner of the sleeve 13.

[0036] The function of the placement block 212 is to provide support and cushioning when the cutter head 20 is placed inside the sleeve 13. The placement block 212 abuts against the bottom and bottom corners of the sleeve 13, dispersing the pressure of the cutter head 20 on the bottom of the sleeve 13 and preventing deformation of the sleeve 13 due to excessive local pressure. Simultaneously, when encountering vibrations during transport, the placement block 212 can absorb some of the vibration energy, reducing the impact on the drill bit inside the cutter head 20 and protecting it from damage. In one embodiment, four placement blocks 212 are bonded to the bottom of the support plate 21, located at the four corners of the support plate 21. When the cutter head 20 is inserted into the sleeve 13, the four placement blocks 212 abut against the bottom plate 11 and corners of the sleeve 13, respectively, thus positioning the cutter head 20.

[0037] Furthermore, a pusher 14 is connected to one side of the transfer vehicle body 10. The pusher 14 is horizontally positioned and is used to push and pull the transfer vehicle body 10.

[0038] The horizontally positioned push handle 14 conforms to ergonomic principles, allowing operators to naturally extend their arms when pushing and pulling the transfer cart, reducing fatigue during operation. The push handle 14 facilitates the movement of the transfer cart, enabling operators to easily control its direction and speed, whether turning in narrow spaces or moving between different surfaces, thus improving its maneuverability and flexibility. Furthermore, the push handle 14 is covered with a non-slip rubber sleeve, enhancing grip comfort.

[0039] Furthermore, the roller 15 is provided with a locking mechanism 151 for locking the roller 15.

[0040] The locking mechanism 151 is crucial. Once the transfer vehicle reaches its designated position, the operator can lock the rollers 15 using the locking mechanism 151 to prevent the transfer vehicle from moving due to accidental collisions or uneven ground, thus ensuring the stability of the cutter head 20 on the transfer vehicle. Especially during the loading and unloading of the cutter head 20, locking the rollers 15 prevents the transfer vehicle from sliding, ensuring operator safety and improving work efficiency. In one embodiment, rollers 15 are bolted to the four corners of the bottom of the transfer cabinet. Each roller 15 is a caster wheel, and each roller 15 is equipped with a foot-operated locking mechanism 151. Stepping on the locking pedal secures the roller 15, while lifting the pedal releases it.

[0041] In use, the operator aligns the support plate 21 of the cutter head 20 with the opening of the sleeve 13 using the handle 23, and inserts the slider 211 into the sleeve 13 after aligning it with the groove 131, until the placement block 212 abuts against the inner wall of the sleeve 13. At this time, the cover plate 22 closes the opening of the sleeve 13. The operator observes the information of the cutter head 20 through the transparent sleeve 13, and places the cutter heads 20 of the same machine with 6 axes into the corresponding columns and rows of the sleeve 13 according to the axis number and coaxial identifier corresponding to the matrix partition. The operator pushes the pusher 14, and moves the transfer cart to the target position through the universal wheels. The operator steps on the locking mechanism 151 to fix the roller 15, thus completing the transfer and storage of the cutter head 20.
