Description

Technical Field

[0001] This utility model relates to the field of workpiece marking, and in particular to a marking device. Background Technology

[0002] Some electronic devices have irregularly shaped internal holes, such as... Figure 1 As shown, the inner hole of the cylindrical device has a sharp point 100. In order to quickly find the sharp point 100 during the production process, it is often necessary to make a label hole on the outer surface of the cylindrical device so that the label hole corresponds to the position of the sharp point 100, which will facilitate subsequent processing.

[0003] The outer diameter of electronic components is generally 1cm and the inner diameter is 0.5cm. The current marking process involves the operator using a flashlight to visually observe the inner hole of the cylindrical component, find the sharp point, and then place the electronic component on a fixture to clamp it so that the sharp point is directly below the marking mechanism. Then, the marking mechanism punches a hole on the outer surface of the electronic component. The current marking mechanism is generally a laser drilling machine.

[0004] The existing clamp consists of a fixed jaw and a movable jaw. During clamping, the workpiece is unsupported and suspended in mid-air. Because the electronic components of the workpiece are small, even slight hand tremors can cause the tip to shift, requiring the clamp to be released for fine-tuning and repeated clamping. This operation is extremely cumbersome. Furthermore, visually inspecting the internal hole with a flashlight is necessary, making the process very complicated.

[0005] Therefore, it is particularly necessary to provide a device that can quickly and accurately clamp workpieces, ensure that the tip of the inner hole is located directly below the marking mechanism, and facilitate observation of the shape of the inner hole. Utility Model Content

[0006] The purpose of this utility model is to provide a marking device that can quickly and accurately clamp the workpiece, ensure that the tip of the inner hole is located directly below the marking machine, and facilitate the observation of the shape of the inner hole.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A marking device includes a camera, a workpiece rotation positioning device, and a marking mechanism. The workpiece rotation positioning device includes a base, a rotating shaft, and a positioning component. The rotating shaft is rotatably mounted on the base, with both ends extending out of the base, one end of which is used to connect to a workpiece. The positioning component is inserted into the base and abuts against the side of the rotating shaft to restrict its rotation. The camera is located next to the workpiece rotation positioning device, with its lens center axis coinciding with the axis of the rotating shaft and aligned with the end of the rotating shaft connected to the workpiece. The camera is connected to a controller, which is equipped with a display device. The marking mechanism is located above the rotating shaft, near the end of the rotating shaft connected to the workpiece.

[0009] Furthermore, the camera is mounted on the base via a camera mounting bracket; the base of the workpiece rotation positioning device is fixedly mounted on the base; the marking mechanism is located at the lower end of the lifting mechanism, the upper end of the lifting mechanism is connected to the crossbeam, one end of the crossbeam is connected to the upper end of the column, and the lower end of the column is fixedly mounted on the base.

[0010] Furthermore, the base has a through-hole for mounting a rotating shaft, which is horizontally positioned. The rotating shaft is rotatably mounted within the mounting hole, with both ends extending out of the mounting hole. The base also has a through-hole for positioning, which communicates with and is perpendicular to the mounting hole. A positioning element is inserted into the positioning hole, and when the positioning element moves toward the mounting hole, it abuts against the side of the rotating shaft to restrict its rotation.

[0011] Furthermore, the positioning element is a positioning bolt, and the positioning hole is provided with an internal thread that matches the positioning bolt.

[0012] Furthermore, the top of the base is an inclined surface, and the positioning hole penetrates vertically through the inclined surface and communicates with the shaft mounting hole.

[0013] Furthermore, the top of the base is provided with two inclined surfaces, which are symmetrically arranged about the vertical plane where the rotating shaft mounting hole is located. Positioning holes are provided on both inclined surfaces, and the positioning holes are symmetrically arranged about the vertical plane where the rotating shaft mounting hole is located.

[0014] Furthermore, both the lifting mechanism and the marking mechanism are connected to and controlled by a controller, which is also equipped with control buttons.

[0015] Furthermore, a fill light is provided around the camera lens, and the fill light is connected to the controller.

[0016] Furthermore, the fill light comprises multiple lights, which are arranged around the lens.

[0017] Furthermore, the controller is connected to the mobile terminal via wireless communication.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] The combination of the base and the rotating shaft ensures that workpieces such as electronic components are no longer suspended in the air during clamping, but are fixed on the rotating shaft, avoiding tip displacement caused by manual shaking. By inserting the positioning element into the positioning hole and abutting against the rotating shaft, the shaft position can be quickly locked, ensuring that the tip of the inner hole is accurately located in the specified position, such as directly below the marking machine. This reduces the number of repeated clamping and fine-tuning operations, improving clamping efficiency and accuracy.

[0020] The lens axis coincides with the rotating axis, allowing the image of the inner hole to be displayed on the display device. Operators can intuitively adjust the apex to the marking position by rotating the rotating axis. The camera observation, workpiece rotation positioning, and marking mechanism work together to replace the cumbersome process of traditional naked-eye observation, repeated clamping, and marking, effectively improving efficiency and accuracy.

[0031] A marking device includes a camera 3, a workpiece rotation positioning device, and a marking mechanism 7. The workpiece rotation positioning device includes a base 10, a rotating shaft 11, and a positioning component. The rotating shaft 11 is rotatably mounted on the base 10, with both ends extending out of the base 10, one end of which is used to connect to a workpiece. The positioning component is inserted into the base 10 and abuts against the side of the rotating shaft 11 to restrict its rotation. The camera 3 is located next to the workpiece rotation positioning device, with its lens center axis coinciding with the axis of the rotating shaft 11 and aligned with the end of the rotating shaft 11 connected to the workpiece. The camera 3 is connected to a controller, which is equipped with a display device. The marking mechanism 7 is located above the rotating shaft 11, close to the end of the rotating shaft 11 connected to the workpiece.

[0032] Due to the above structure, when using it, the workpiece is first installed on one end of the rotating shaft 11, and then the other end of the rotating shaft 11 is manually rotated to rotate the workpiece and make fine adjustments to its position. The camera 3 acquires an image of the inner hole. The operator only needs to manually rotate the rotating shaft 11 to see if the tip 100 on the display device is in the correct position. There is no need to look at the tip 100 with the naked eye. The marking mechanism 7 is located directly above the workpiece. After fine adjustment, the rotation of the rotating shaft 11 is restricted by the positioning component. At this time, the marking mechanism 7 can emit a laser to mark a label hole on the outer surface of the workpiece.

[0033] The combination of the base 10 and the rotating shaft 11 ensures that electronic components are no longer suspended in the air during clamping, but are fixed on the rotating shaft 11, preventing the tip 100 from shifting due to manual shaking. By inserting the positioning element into the positioning hole 102 and abutting against the rotating shaft 11, the position of the rotating shaft 11 can be quickly locked, ensuring that the inner hole tip 100 is accurately located in the specified position, such as directly below the marking machine. This reduces the number of repeated clamping and fine-tuning operations, improving clamping efficiency and accuracy.

[0034] The lens axis coincides with the axis of the rotating shaft 11, allowing the image of the inner hole to be displayed on the display device. The operator can intuitively adjust the tip 100 to the marking position by rotating the rotating shaft 11. The camera 3 observes, the workpiece rotates and positions, and the marking mechanism 7 work together to replace the cumbersome process of traditional naked-eye observation, repeated clamping, and marking, effectively improving efficiency and accuracy.

[0035] In this utility model, a workpiece mounting hole is provided at one end of the rotating shaft 11 that connects to the workpiece. The diameter of the workpiece mounting hole matches the diameter of the workpiece, making it convenient for the workpiece to be directly inserted into the workpiece mounting hole. A handwheel 9 can be installed at the other end of the rotating shaft 11 to make it easier to rotate the rotating shaft 11.

[0036] Furthermore, the camera 3 is mounted on the base 1 via the camera mounting bracket 2; the base 10 of the workpiece rotation positioning device is fixedly mounted on the base 1 at its bottom; the marking mechanism 7 is located at the lower end of the lifting mechanism 4, the upper end of the lifting mechanism 4 is connected to the crossbeam 5, one end of the crossbeam 5 is connected to the upper end of the column 6, and the lower end of the column 6 is fixedly mounted on the base 1.

[0037] Furthermore, the base 10 has a through-hole 101 for mounting a rotating shaft, which is horizontally positioned. The rotating shaft 11 is rotatably mounted in the rotating shaft mounting hole 101, with both ends of the rotating shaft 11 extending out of the rotating shaft mounting hole 101. The base 10 also has a through-hole 102 for positioning, which communicates with and is perpendicular to the rotating shaft mounting hole 101. A positioning element is inserted into the positioning hole 102, and when the positioning element moves toward the rotating shaft mounting hole 101, it abuts against the side of the rotating shaft 11 to restrict its rotation.

[0038] Furthermore, the positioning element is a positioning bolt 8, and the positioning hole 102 is provided with an internal thread that matches the positioning bolt 8.

[0039] By screwing the bolts into and out of the positioning holes 102, the rotation of the shaft 11 can be easily restricted, and the threaded connection is reliable and provides a strong mechanical lock.

[0040] Furthermore, a bearing is provided in the shaft mounting hole 101, and the shaft 11 is mounted in the shaft mounting hole 101 through the bearing.

[0041] Without bearings, the mounting holes 101 and the shaft 11 are prone to wear, affecting clamping accuracy. The presence of bearings prevents wear, ensures clamping accuracy, and extends the equipment's lifespan.

[0042] Furthermore, the top of the base 10 is an inclined surface, and the positioning hole 102 vertically penetrates the inclined surface and communicates with the rotating shaft mounting hole 101.

[0043] The inclined design of the positioning hole 102 makes it easier to operate the bolts, reduces blind spots and errors, and improves clamping speed and accuracy.

[0044] Furthermore, the top of the base 10 is provided with two inclined surfaces, which are symmetrically arranged about the vertical plane where the rotating shaft mounting hole 101 is located. Positioning holes 102 are provided on both inclined surfaces, and the positioning holes 102 are symmetrically arranged about the vertical plane where the rotating shaft mounting hole 101 is located.

[0045] The symmetrical double-inclined surface and double positioning hole 102 design provides multi-directional operational flexibility, allowing the rotating shaft 11 to be locked from both sides, enhancing the stability and convenience of the device, and making it suitable for different operators' habits. At the same time, when bolts are inserted into the positioning holes 102 simultaneously, it ensures that the rotating shaft 11 is more securely fixed.

[0046] Furthermore, the shaft section of the rotating shaft 11 located within the rotating shaft mounting hole 101 is provided with an anti-slip structure.

[0047] The anti-slip structure increases the friction between the surface of the rotating shaft 11 and the positioning component, which can prevent the rotating shaft 11 from slipping under vibration or external force.

[0048] Furthermore, the anti-slip structure consists of protrusions or grooves covering the circumference of the rotating shaft 11.

[0049] Furthermore, both the lifting mechanism 4 and the marking mechanism 7 are connected to and controlled by a controller, which is also equipped with control buttons. In this invention, the lifting mechanism 4 can be a cylinder, an electric lifting rod, etc., and the marking mechanism 7 is a light-drilling machine. Due to the presence of the lifting mechanism 4, the distance between the marking mechanism 7 and the workpiece can be adjusted, facilitating more accurate drilling. Simultaneously, since all components are connected to and controlled by the controller, the actions of each component can be more conveniently controlled via the control buttons, making operation more convenient.

[0050] Furthermore, a fill light is also provided around the lens of the camera 3, and the fill light is connected to the controller. Multiple fill lights are arranged around the lens. The presence of the fill light ensures that the camera 3 captures clearer images.

[0051] Furthermore, the controller is connected to a mobile terminal via wireless communication. The mobile terminal is a mobile phone; its presence allows for observation of the internal holes and issuance of operational commands, making operation more convenient.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
