Furthermore, by setting one end of the output shaft extending outside the device housing as a first shape, and the hole on the laser head's adjustment knob as a second shape, and by fitting the first and second shapes together, when autofocusing the laser head is required, the first-shaped end of the output shaft is inserted into the second-shaped hole of the adjustment knob. When manual focus is required, the first-shaped end of the output shaft is pulled out of the second-shaped hole of the adjustment knob.

[0008] In the above implementation process, by placing the driver inside the focusing device, there is no need to place the driver in the laser head, which further simplifies the structure of the laser head. In addition, since both the driver and the power component are located inside the focusing device, the connecting wiring harness between the driver and the power component can be shortened, simplifying the wiring harness layout and saving wiring harness costs.

[0009] In one embodiment, one end of the drive harness that passes through the device housing is an aviation plug.

[0020] In the above implementation process, by setting a focusing device, which can be used for automatic adjustment and is independent of the laser head, the structure of the autofocus laser head can be simplified and costs reduced. Furthermore, by setting one end of the output shaft extending outside the device housing as a first shape and the hole on the laser head's adjustment knob as a second shape, and by ensuring the first and second shapes are compatible, when autofocusing the laser head is required, the first-shaped end of the output shaft is inserted into the second-shaped hole of the adjustment knob. When manual focus is required, the first-shaped end of the output shaft is pulled out of the second-shaped hole of the adjustment knob.

[0040] Against the backdrop of continuous innovation and rapid development in laser technology, autofocus laser heads, as a significant technological innovation in the field of high-precision machining, have been widely applied in various industrial processing scenarios. These laser heads, through built-in high-precision sensors and advanced control algorithms, can achieve rapid and precise focusing on the processed materials, thereby significantly improving the efficiency and accuracy of processes such as laser cutting, welding, and marking.

[0041] However, despite the significant technological advantages of autofocus laser heads, their complex internal structure also leads to high manufacturing and maintenance costs. This includes the processing costs of precision components, complex assembly processes, and the need for regular professional maintenance, all of which present a certain economic barrier to the widespread application of autofocus laser heads.

[0042] In contrast, manual laser cutting heads maintain an irreplaceable position in the laser cutting field due to their simple structure, compact design, light weight, and low manufacturing and maintenance costs. Manual laser cutting heads typically do not require complex autofocus mechanisms, relying instead on the operator's experience and skills for focusing. While they may be slightly less efficient and automated than autofocus laser heads, they exhibit unique advantages in cost control, flexible application, and adaptability to specific processing needs. Therefore, while pursuing efficient and automated production, manual laser cutting heads remain an indispensable choice for many small and medium-sized enterprises and specific processing tasks. Their widespread application in laser processing further promotes the diversified development of laser technology.

[0043] In view of this, this application proposes a focusing device that can be used to automatically adjust the focal length. This focusing device is independent of the laser head, simplifying the structure of the autofocus laser head and reducing costs. Furthermore, by designing a first shape for one end of the output shaft extending outside the device housing, and a second shape for the hole on the laser head's adjustment knob, the first and second shapes are adapted to each other. When autofocusing the laser head is required, the first-shaped end of the output shaft is inserted into the second-shaped hole of the adjustment knob. When manual focus is required, the first-shaped end of the output shaft is pulled out of the second-shaped hole of the adjustment knob. This allows for easy switching between autofocus and manual focus, improving the flexibility of the laser head's focusing method and expanding its application scenarios.

[0044] like Figure 1 , Figure 2 The diagram shown is a schematic of a focusing device provided in an embodiment of this application, including: a power component 110, an output shaft 120, and a device housing 130.

[0045] The power component 110 is disposed inside the device housing 130; the output shaft 120 is connected to the power component 110; one end of the output shaft 120 passes through the device housing 130 and extends to the outside of the device housing 130; the end of the output shaft 120 extending to the outside of the device housing 130 is configured with a first shape.

[0046] The power component 110 here refers to the component used to provide power, which can be an electric motor, motor, etc. The power component 110 can be selected according to the actual situation.

[0047] The aforementioned output shaft 120 can be a drive shaft used to transmit power or torque. The output shaft 120 is configured to rotate under the action of the power unit 110.

[0048] In one embodiment, the hole on the adjustment knob 210 of the laser head 20 is configured in a second shape.

[0049] The first and second shapes are adapted to each other. For example, the first and second shapes may be identical, complementary, etc. The setting of the first and second shapes can be selected according to the actual situation.

[0050] The focusing device 10 here is configured such that one end of the output shaft 120 extends to the outside of the device housing 130 and is fitted into the hole on the adjusting knob 210, and is detachably connected to the laser head 20.

[0051] The focusing device 10 is configured to adjust the focal length of the laser head 20 via the output shaft 120.

[0052] Understandably, such as Figure 3As shown, due to the compatibility of the first and second shapes, the end of the output shaft 120 of the first shape can be inserted into the hole of the second shape. When the output shaft 120 rotates under the action of the power component 110, it can drive the adjustment knob 210 to rotate, thereby realizing automatic adjustment of the focal length of the laser head 20. When the focusing device 10 cannot be used, the output shaft 120 of the focusing device 10 can be pulled out from the hole on the adjustment knob 210, and the user can manually rotate the adjustment knob 210 to achieve manual focusing.

[0053] For example, the output shaft 120 has a hexagonal cross-section at one end extending outside the device housing 130, and the hole on the adjustment knob 210 is a hexagonal hole, the hexagonal cross-section of which matches the hexagonal hole of the adjustment knob 210. When autofocus is required, the hexagonal end of the output shaft 120 is inserted into the hexagonal hole of the focusing knob, and the output shaft 120 achieves autofocus by transmitting power or torque from the power unit 110 to the adjustment knob 210. When manual focus is required, the hexagonal end of the output shaft 120 is pulled out of the hexagonal hole of the focusing knob, and manual focus is achieved by operating the adjustment knob 210.

[0054] In the above implementation process, by setting a focusing device 10, which can be used to automatically adjust the focal length, and which is independent of the laser head 20, the structure of the autofocus laser head 20 can be simplified and the cost reduced. Furthermore, by setting one end of the output shaft 120 extending outside the device housing 130 to a first shape, and the hole on the adjustment knob 210 of the laser head 20 to a second shape, and by fitting the first and second shapes together, when autofocusing of the laser head 20 is required, the first-shaped end of the output shaft 120 is inserted into the second-shaped hole of the adjustment knob 210. When manual focus of the laser head 20 is required, the first-shaped end of the output shaft 120 is pulled out from the second-shaped hole of the adjustment knob 210. This allows for easy switching between autofocus and manual focus of the laser head 20, improving the flexibility of the laser head 20's focusing method and expanding its application scenarios.

[0055] In one possible implementation, the focusing device 10 further includes a driver 140 and a drive harness 150.

[0056] The driver 140 is located inside the device housing 130; the driver 140 is connected to the power unit 110; one end of the drive harness 150 is connected to the driver 140; the other end of the drive harness 150 passes through the device housing 130.

[0057] The driver 140 here can be used to convert control signals into electrical energy output, and the driver 140 is configured to drive the power unit 110 to operate.

[0058] The other end of the aforementioned drive harness 150 is configured to connect to an external device. The drive harness 150 is used to transmit one or more of the signals such as power signals, control signals, and feedback signals from the external device to the driver 140.

[0059] It should be understood that after the driver 140 receives the signal transmitted by the drive harness 150, it processes the signal accordingly and then controls the motor to operate through the processed signal.

[0060] Optionally, the drive harness 150 may include one or more wires. The drive harness 150 may include one or more types of wires such as power lines, signal lines, and control lines. The number and type of wires in the drive harness 150 can be selected according to actual needs.

[0061] In the above implementation process, by placing the driver 140 inside the focusing device 10, it is no longer necessary to place the driver 140 in the laser head 20, which can further simplify the structure of the laser head 20. In addition, since both the driver 140 and the power component 110 are placed inside the focusing device 10, the connecting wire harness between the driver 140 and the power component 110 can be shortened, simplifying the wiring harness layout and saving wiring harness costs.

[0062] In one possible implementation, such as Figure 2 As shown, the drive harness 150 passes through one end of the device housing 130 and is a connector.

[0063] The connector mentioned here is a type of connector used to connect power or signals.

[0064] The connector conducts electrical signals through the contact between pins and sockets. The metal contact between the pins and sockets enables the transmission of electrical signals. The design of the pins and sockets ensures that the connector maintains stable electrical performance during insertion and removal, allowing it to function normally even in harsh environments.

[0065] In the above implementation process, by setting one end of the drive harness 150 that passes through the device housing 130 as an aviation connector, and since the aviation connector has a pin and socket design, it can maintain stable electrical performance during insertion and removal, thus improving stability. In addition, since the aviation connector is connected by inserting and removing pins, compared to connecting via wires, the connection can be simplified and the connection difficulty reduced.

[0066] In one possible implementation, the focusing device 10 further includes a speed reducer 160.

[0067] The reducer 160 is located inside the housing 130 of the device; the reducer 160 connects the power component 110 and the output shaft 120.

[0068] The reducer 160 here is a mechanical device used to reduce the speed of the drive unit and correspondingly increase the torque. The reducer 160 is configured to match the torque between the power unit 110 and the output shaft 120.

[0069] Understandably, the reducer 160 connects a high-speed rotating input component to a low-speed rotating output component via an internal gear, worm, or other transmission mechanism. When the input component rotates at a higher speed, the output component rotates at a lower speed through the internal transmission mechanism of the reducer 160, thus achieving speed reduction.

[0070] In the above implementation process, by setting a reducer 160 in the focusing device 10, and the reducer 160 connecting the power component 110 and the output shaft 120, it can be used to match the torque between the power component 110 and the output shaft 120, thereby reducing the requirements of the focusing device 10 on the motor and reducing costs.

[0071] In one possible implementation, the focusing device 10 further includes an encoder 170.

[0072] The encoder 170 is located inside the housing 130 of the device; the encoder 170 is connected to the output shaft 120.

[0073] The encoder 170 here is a device that encodes and converts signals or data into a signal form that can be used for communication, transmission, and storage. The encoder 170 is configured to adjust the focusing accuracy of the focusing device 10.

[0074] Understandably, during the operation of the power unit 110, the encoder 170 continuously sends position and speed feedback signals to the controller. Based on these feedback signals, the controller calculates the actual position and speed of the power unit 110 in real time and compares them with the target value. If there is a deviation, the controller calculates a correction amount according to a preset control algorithm and adjusts the drive signal of the power unit 110 to make the actual output of the power unit 110 closer to the target value, thereby achieving the adjustment accuracy of the focusing device 10.

[0075] Optionally, the encoder 170 can be an optical encoder 170, a magnetic encoder 170, a capacitive encoder 170, an inductive encoder 170, etc. The type of encoder 170 can be selected according to the actual situation.

[0076] In the above implementation process, by setting an encoder 170 in the focusing device 10, the encoder 170 can be used to adjust the adjustment accuracy of the focusing device 10, thereby improving the focusing accuracy of the focusing device 10.

[0077] In one possible implementation, such as Figure 4As shown, the focusing device 10 also includes a dial 180.

[0078] The dial 180 is mounted on the device housing 130.

[0079] The dial 180 here is used to display the focusing accuracy. The focusing dynamics of the laser head 20 can be observed through this dial.

[0080] In one embodiment, the dial 180 is located on the outside of the device housing 130 on the side away from the adjustment knob 210.

[0081] In the above implementation process, by setting a dial 180 on the side of the device housing 130 away from the adjustment knob 210, the real-time focusing dynamics of the laser head 20 can be reflected through the dial 180, which facilitates the control of the focusing situation.

[0082] In one possible implementation, the focusing device 10 further includes a protective housing 190.

[0083] The protective shell 190 has a semi-enclosed structure; the device outer shell 130 is located inside the protective shell 190.

[0084] The protective shell 190 here is configured to connect with the plane where the adjustment knob 210 is located.

[0085] Understandably, after connecting the focusing device 10 to the laser head 20, the open side of the protective housing 190 is connected to the plane where the adjustment knob 210 is located. At this time, the focusing device 10 is configured with the protective housing 190 and the laser head 20 enclosed within the protective housing 190, thereby protecting the focusing device 10 through the protective housing 190.

[0086] Optionally, the protective shell 190 can be made of materials such as plastic, rubber, or metal, and the material of the protective shell 190 can be selected according to the actual situation.

[0087] The aforementioned protective shell 190 can be connected to the laser head 20 by screws, bolts, snap-fit, or other connection methods.

[0088] In the above implementation process, by setting a protective shell 190, the protective shell 190 can protect the device housing 130 and its internal components, prevent damage to the device housing 130 and its internal components, and extend the service life of the focusing device 10.

[0089] like Figure 3 , Figure 4 , Figure 5 The diagram shown is a schematic diagram of a focusing system provided in an embodiment of this application, including: the focusing device 10 and the laser head 20 in the above embodiment.

[0090] The laser head 20 includes a lens barrel 220 and an adjustment knob 210. The lens barrel 220 is disposed inside the laser head 20. The adjustment knob 210 is connected to the lens barrel 220. An adjustment hole is provided on one side of the laser head 20, and a groove is provided in the adjustment hole. The adjustment knob 210 is disposed in the groove, and a hole is provided on the adjustment knob 210.

[0091] The adjustment knob 210 here is configured to adjust the position of the lens barrel 220 by rotation. The lens barrel 220 can be used to mount one or more lenses.

[0092] In one embodiment, the adjustment knob 210 is configured to rotate within a recess.

[0093] The focal length of the lenses in the lens barrel 220 may be different depending on the position of the lens barrel 220.

[0094] The aforementioned hole is configured in a second shape, and the end of the output shaft 120 of the focusing device 10 extending to the outside of the device housing 130 is configured in a first shape, and the first shape and the second shape are adapted to each other.

[0095] The focusing device 10 here is configured such that one end of the output shaft 120 extends to the outside of the device housing 130 and is fitted into the hole on the adjusting knob 210, and is detachably connected to the laser head 20; the focusing device 10 is configured to adjust the focal length of the laser head 20 through the output shaft 120.

[0096] In one embodiment, the lens barrel 220 is held inside the laser head 20 by a support ring 230.

[0097] In the above implementation process, by setting a focusing device 10, which can be used for automatic adjustment and is independent of the laser head 20, the structure of the automatic focusing laser head 20 can be simplified and the cost reduced. Furthermore, by setting one end of the output shaft 120 extending outside the device housing 130 to a first shape, and the hole on the adjustment knob 210 of the laser head 20 to a second shape, and by fitting the first and second shapes together, when automatic focusing of the laser head 20 is required, the first-shaped end of the output shaft 120 is inserted into the second-shaped hole of the adjustment knob 210. When manual focusing of the laser head 20 is required, the first-shaped end of the output shaft 120 is pulled out from the second-shaped hole of the adjustment knob 210. This allows for easy switching between automatic and manual focusing of the laser head 20, improving the flexibility of the focusing method and expanding application scenarios.

[0098] In one possible implementation, such as Figure 6 , Figure 7 As shown, the laser head 20 also includes a protrusion 240.

[0099] The protrusion 240 is disposed on the body of the laser head 20; a vertical groove 221 is provided on the side of the lens barrel 220; the protrusion 240 is embedded in the vertical groove 221.

[0100] Optionally, the protrusion 240 can be integrated with the body, or it can be connected to the body by screws, bolts, snap-fits, or welding. The connection method between the protrusion 240 and the body can be selected according to the actual situation.

[0101] The protrusion 240 here is configured to slide within the vertical groove 221. The protrusion 240 is configured to restrict the lens barrel 220 from sliding up and down within the body and prevent the lens barrel 220 from rotating.

[0102] It is understandable that, since the protrusion 240 is embedded in the vertical groove 221 on the side of the lens barrel 220, when the position of the lens barrel 220 is adjusted by adjusting the knob 210, the lens barrel 220 can only slide up and down in the body under the restriction of the protrusion 240, thereby restricting the lens barrel 220 from rotating in the direction of the lens plane of the lens barrel 220.

[0103] Optionally, the protrusion 240 can be a convex screw, convex bolt, protrusion, etc., and the protrusion 240 can be selected according to the actual situation.

[0104] In the above implementation process, by setting a protrusion 240 on the body and embedding the protrusion 240 into the vertical groove 221 on the side of the lens barrel 220, when adjusting the lens barrel 220 by adjusting the knob 210, the lens barrel 220 can be restricted from sliding up and down in the body, thus preventing the lens barrel 220 from rotating and improving focusing accuracy.

[0105] In one possible implementation, the adjustment knob 210 is provided with a protruding pin 211.

[0106] The lens barrel 220 is provided with a horizontal groove 222; the protruding pin 211 is embedded in the horizontal groove 222.

[0107] Optionally, the protruding pin 211 can be integrated with the adjusting knob 210. The protruding pin 211 can also be connected to the adjusting knob 210 by means of screws, bolts, snap-fit, etc. The protruding pin 211 can also be connected to the adjusting knob 210 by welding. The connection method between the protruding pin 211 and the adjusting knob 210 can be selected according to the actual situation.

[0108] The protruding pin 211 here is configured to slide within the transverse groove 222.

[0109] The adjustment knob 210 is configured to slide within the transverse groove 222 by rotating the adjustment pin 211, thereby moving the lens barrel 220.

[0110] Understandably, since the adjustment knob 210 is located in the groove, the protrusion 211 on the adjustment knob 210 can only slide within the groove, thus restricting the adjustment knob 210 to rotate only within a fixed angle of the groove.

[0111] The protruding pin 211 is embedded in the transverse groove 222 on the lens barrel 220 and can slide freely within the transverse groove 222. If the adjustment knob 210 is rotated at a certain angle, the protruding pin 211 on the adjustment knob 210 slides in the groove, and the protruding pin 211 moves relative to the vertical position of the body, thereby driving the lens barrel 220 to move up and down through the transverse groove 222 on the side of the lens barrel 220.

[0112] Optionally, the protruding pin 211 can be a protruding screw, a protruding bolt, a protrusion, etc., and the protruding pin 211 can be selected according to the actual situation.

[0113] In the above implementation process, by setting a protruding pin 211 on the adjustment knob 210 and embedding the protruding pin 211 into the transverse groove 222 on the lens barrel 220, the adjustment knob 210 can be rotated to drive the protruding pin 211 to slide in the transverse groove 222 of the lens barrel 220, thereby adjusting the position of the lens barrel 220 and achieving focusing, thus simplifying the focusing structure.
