[0002] With the rapid development of the new energy industry, lithium battery production has fully entered the era of automation. Automated production lines place extremely high demands on equipment positioning accuracy, operational stability, and safety, especially for chemical composition equipment in the back-end production of batteries, which accounts for a large proportion and needs to maintain high precision for a long time. However, during the operation of the equipment, the resonance phenomenon caused by mechanical vibration can easily cause equipment displacement, resulting in a decrease in the accuracy of upstream and downstream docking, seriously affecting production efficiency and product consistency. To solve this problem, it is usually necessary to fasten the equipment to the ground with chemical anchors to suppress displacement.

[0023] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0024] This embodiment discloses an automatic drilling device for drilling a hole on a target surface (such as the ground), and the hole may be an anchor hole.

[0025] like Figures 1 to 4 The drilling device includes a chassis 1 , which includes a side portion 10 , a top portion 11 located above the side portion 10 , and a bottom portion 12 located below the side portion 10 .

[0026] The side portion 10 is a closed structure (such as a rectangular or cylindrical frame) to form a receiving space 13 therein. The top portion 11 has a first opening 14 communicating with the receiving space 13 , and the bottom portion 12 has a second opening 15 communicating with the receiving space 13 .

[0027] A drill bit 2 is disposed in the accommodating space 13 , and the drill bit 2 is slidably connected to the inner wall of the side portion 10 through the bracket 3 , so that the drill bit 2 can move up and down along the inner wall of the side portion 10 , and the drill bit 2 contacts the target surface to be drilled based on the second opening 15 .

[0028] The top 11 is also provided with a lifting mechanism 5 connected to the bracket 3 based on the first opening 14 , and the lifting mechanism 5 is used for lifting and positioning the bracket 3 .

[0029] The bottom 12 is also provided with a walking mechanism 4, which is used to drive the chassis 1 to roll and walk.

[0030] Specifically, the running mechanism 4 includes two sets of symmetrically distributed universal rollers. In addition, crawler tracks can also be used as the running mechanism 4.

[0031] For the drilling device in this embodiment, its working principle is as follows:

[0032] 1. Mobile positioning: The chassis 1 is moved to the target drilling position through the walking mechanism 4 at the bottom 12.

[0033] 2. Pressing the drill bit 2 downward: the lifting mechanism 5 is released, and the support 3 carries the drill bit 2 and slides downward along the inner wall of the side portion 10 due to gravity until the tip of the drill bit 2 contacts the target surface through the second opening 15 .

[0034] 3. Drilling operation: The drill bit 2 starts to rotate and applies downward pressure, and stops after drilling is completed.

[0035] 4. Reset the drill bit 2: lift the drill bit 2 into the accommodating space 13 through the lifting mechanism 5 to prevent the drill bit 2 from being exposed.

[0036] 5. Move to the next position: The walking mechanism 4 drives the chassis 1 to the next drilling point and repeats the above process.

[0037] Thus, the drilling device with the above structure wraps the drill bit 2 in the chassis 1 to prevent the drill bit 2 from being exposed outside, effectively preventing flying chips from splashing or people from accidentally touching the drill bit 2 during operation, and significantly reducing the risk of work-related injuries. In addition, the drill bit 2 can achieve precise vertical movement through the sliding connection between the bracket 3 and the inner wall of the side 10. The positioning control of the bracket 3 by the lifting mechanism 5 at the top 11 can quickly adjust the height of the drill bit 2 and lock the position, avoiding repeated manual calibration and improving the drilling positioning accuracy and efficiency. Furthermore, the walking mechanism 4 set at the bottom 12 supports the rolling movement of the chassis 1, which facilitates the overall movement of the device to the target position, reduces the time-consuming manual handling and position adjustment, and is particularly suitable for scenes where batch drilling of positioning holes 503 is required.

[0038] On the other hand, the side 10 and / or the top 11 are also provided with an observation window 19 to facilitate the operator to observe the projection position of the drill bit 2 on the target surface. Specifically, a window can be provided in the side 10 and / or the top 11, and glass or a transparent plate can be embedded in the window.

[0039] On the other hand, the top 11 of the chassis 1 is also provided with an operating switch 16 electrically connected to the drill bit 2, and the operating switch 16 is used to control the working state of the drill bit 2. The setting of the operating switch 16 facilitates the operator to control the drill bit 2.

[0040] On the other hand, a light generator G is also disposed in the accommodating space 13 , and the light generator G is used to project a light mark toward the target surface through the second opening 15 , and the light mark corresponds to the impact point of the drill bit 2 .

[0041] The light generator G in this embodiment includes an infrared light generator or a laser generator. When the chassis 1 moves, the light generator G projects a light mark (such as a cross cursor) to the target surface through the second opening 15. When the light mark coincides with the target drilling position, the chassis 1 stops moving. At this time, the drill bit 2 is opposite to the target drilling position, and the drill bit 2 can drill the target drilling position after it falls. Therefore, by setting the light generator G, the surface drilling position and the target position can be misaligned.

[0042] On the other hand, two slide grooves 16 are arranged opposite to each other on one side wall of the accommodating space 13. The bracket 3 includes a base plate 30 and a plurality of guide mechanisms 31 arranged on both sides of the base plate 30. The guide mechanisms 31 are slidably connected to the slide grooves 16 on the corresponding sides to guide the base plate 30 to move up and down along the slide grooves 16. The drill bit 2 is arranged on the base plate 30.

[0043] Specifically, the guide mechanism 31 includes a first guide wheel 310 and a second guide wheel 311 slidably connected to the slide groove 16 , the axle of the first guide wheel 310 is perpendicular to the depth direction of the slide groove 16 , and the axle of the second guide wheel 311 is parallel to the depth direction of the slide groove 16 .

[0044] In this embodiment, by providing a bilaterally symmetrical slide groove 16 and using a combination of a first guide wheel 310 (the wheel axle is perpendicular to the depth direction of the slide groove 16) and a second guide wheel 311 (the wheel axle is parallel to the depth direction of the slide groove 16), a multi-directional constraint is formed, that is:

[0045] The first guide wheel 310 limits the displacement of the bracket 3 in the depth direction (longitudinal direction in the horizontal plane) of the slide groove 16 .

[0046] The second guide wheel 311 limits the displacement of the bracket 3 in the width direction (lateral direction in the horizontal plane) of the slide slot 16 .

[0047] The synergistic effect of the double slide grooves 16 and the double guide wheels ensures that the bracket 3 can only move smoothly along the vertical direction of the slide grooves 16, significantly improving the straightness of the drill bit 2 during the pressing down and lifting process, avoiding drilling angle deviation, and ensuring the vertical accuracy of drilling.

[0048] In addition, the two guide wheels use rolling friction instead of traditional sliding friction (such as direct contact between the slider and the slide groove 16), which can greatly reduce the friction resistance when the bracket 3 moves, avoid scratches or deformation of the inner wall of the slide groove 16 due to long-term friction, extend the overall service life of the device, and reduce maintenance frequency and cost.

[0049] On the other hand, a trigger 6 is also provided on the base plate 30. When the base plate 30 moves downward to a preset limit position, the trigger 6 sends an electronic trigger signal. The top 11 is also provided with a prompter 18, which is used to send a perceptible prompt signal according to the electronic trigger signal.

[0050] Specifically, when the substrate 30 carries the drill bit 2 and moves down to the extreme position so that the drill bit 2 contacts the target surface, the trigger 6 sends an electronic trigger signal, and the prompter 18 sends a prompt signal based on the electronic trigger signal, and the staff can know the current position of the drill bit 2 based on the prompt signal.

[0051] Furthermore, the trigger 6 includes a trigger switch 60 and a guide rod 61 which is arranged opposite to the trigger switch 60 and located below the trigger switch 60 .

[0052] A mounting seat 62 is provided on the substrate 30, and the guide rod 61 includes a detection end 610 located at the bottom and a trigger end 611 located at the top. The trigger end 611 passes through the mounting seat 62 and is slidably connected to the mounting seat 62 through an elastic member 612. When the detection end 610 abuts against the target surface, the trigger end 611 moves up and abuts against the trigger switch 60, and the elastic member 612 provides an elastic restoring force for the trigger end 611 to reset.

[0053] In this embodiment, the downward position of the substrate 30 is maintained by the cooperation of the trigger switch 60 and the guide rod 61, which is simple and reliable.

[0054] In addition, a stopper is provided at the bottom 12 of the slide groove 16 to limit the base plate 30 from continuing to move downward after reaching the limit position, thereby improving the safety performance of the device.

[0055] On the other hand, the lifting mechanism 5 includes an operating rod 50 and a connecting rod 51. The operating rod 50 includes a fixed end 500, a movable end 501 and a connecting portion 502 located between the fixed end 500 and the movable end 501. The operating rod 50 is pivotally connected to the top 11 based on the fixed end 500. The movable end 501 is used to drive the operating rod 50 to swing up and down with the fixed end 500 as the center. One end of the connecting rod 51 is pivotally connected to the connecting portion 502, and the other end of the connecting rod 51 is pivotally connected to the bracket 3. A positioning structure is also provided on the connecting rod 51, and the positioning structure is used to fix the connecting rod 51 at a certain height position.

[0056] Specifically, the positioning structure includes a plurality of positioning holes 503 spaced apart along the length direction of the connecting rod 51 and positioning pins 7 matched with the positioning holes 503. After the positioning pins 7 are inserted into the positioning holes 503, they can abut against parts on both sides of the first opening 14 to prevent the connecting rod 51 from moving downward.

[0057] In this embodiment, the manual swing operation is converted into the lifting action of the bracket 3 through the lever linkage design of the operating rod 50 and the connecting rod 51, without relying on electric or hydraulic drive devices, reducing manufacturing costs and failure rates, and is particularly suitable for scenarios where there is no power supply or rapid intervention is required.

[0058] The mechanical locking method of the positioning hole 503 and the positioning pin 7 is intuitive and reliable, avoiding the complex control logic of electronic sensors or hydraulic locks and reducing the difficulty of debugging and maintenance.

[0059] In addition, the multiple positioning holes 503 spaced apart on the connecting rod 51 provide multiple height locking options, and the user can flexibly select the gear according to the drilling depth requirements to adapt to different working conditions.

[0060] After being inserted, the positioning pin 7 abuts against both sides of the first opening 14 to form a physical rigid limit, which can effectively resist the vibration impact during the drilling operation, prevent the drill bit 2 from accidentally moving downward, and ensure positioning stability.

[0061] On the other hand, Figure 2 and Figure 3 The side portion 10 is also provided with an interface 17 communicating with the accommodating space 13 . A dust suction pipe 8 is provided in the accommodating space 13 . One end of the dust suction pipe 8 passes through the interface 17 , and the other end of the dust suction pipe 8 is located at the second opening 15 .

[0062] During operation, a vacuum cleaner can be connected to the interface 17 on the side portion 10 to timely discharge dust discharged by the drill bit 2 through the vacuum pipe 8 to avoid affecting the surrounding environment.

[0063] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
