Abstract
Description
Technical Field
[0001] This application relates to the field of marking machine technology, and more particularly to a laser marking device with multiple tooling fixtures. Background Technology
[0002] Laser marking equipment is a device that uses a laser beam to create permanent marks on the surface of various materials. Its working principle involves using a high-energy laser beam to etch, oxidize, melt, or ablate the material surface, thereby forming patterns, text, barcodes, or other markings. Laser marking offers advantages such as high precision, high speed, wear resistance, and environmental friendliness, and is therefore widely used in industries such as electronics, automotive, medical devices, jewelry, and packaging.
[0003] In related technologies, laser marking equipment includes a worktable and a laser marking machine, with a workpiece holder on the worktable. The workpiece holder is used to fix and install the workpiece, and after the workpiece is installed on the workpiece holder, the laser marking machine is used to mark the workpiece.
[0004] However, after marking a workpiece, the laser marking equipment needs to remove the marked workpiece from the workpiece fixture and install the next unmarked workpiece before it can continue marking. During the workpiece removal and installation process, the laser marking machine cannot perform marking, which makes the whole marking process time-consuming and reduces marking efficiency. Utility Model Content

[0015] In some embodiments that may include the above embodiments, in the at least two tooling fixtures, the projection of the axis of each insertion channel onto the corresponding positioning part is equal to the distance between the axis of the rotary table and the axis of the rotary table.
[0016] In some embodiments that may include the above embodiments, the positioning part is closer to the outer periphery of the rotary table than the clamping part.
[0017] In some embodiments that may include the above embodiments, the at least two tooling fixtures are arranged at the same central angle on the rotary table.

Tooling fixtures are respectively installed on the rotating worktables inside and outside the marking room. These fixtures are used to clamp and position workpieces. During the marking process, the rotating worktable rotates intermittently relative to the cabinet, thereby marking the workpieces on the tooling fixtures sequentially. During the intervals when the rotating worktable stops rotating, marked workpieces located outside the marking room can be removed from the tooling fixtures, and / or unmarked workpieces can be installed onto the tooling fixtures. This allows the loading / unloading process and the marking process to be performed simultaneously, increasing the number of workpieces that the laser marking equipment with multiple tooling fixtures can mark per unit time, thus improving marking efficiency.

[0051] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0052] Secondly, it should be noted that in the description of the embodiments of this application, the terms "inner" and "outer" and other terms indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.
[0053] Furthermore, it should be noted that, in the description of the embodiments of this application, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.
[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0055] As described in the background section, laser marking equipment in the related technology suffers from low marking efficiency. The applicant's research has revealed that the reason for this problem is that after marking a workpiece, the laser marking equipment in the related technology needs to remove the marked workpiece from the workpiece fixture and install the next unmarked workpiece before it can continue marking. During the workpiece removal and installation process, the laser marking machine cannot perform marking. In other words, the loading and unloading process and the marking process cannot be carried out simultaneously. This results in a long marking process and reduced marking efficiency when multiple workpieces need to be marked.
[0056] To address the aforementioned technical problems, this application provides a laser marking device with multiple tooling fixtures. A portion of the rotating worktable is located inside the marking chamber, while another portion is located outside. Tooling fixtures are installed on both the indoor and outdoor rotating worktables. These fixtures are used to hold and position workpieces. During the marking process, the rotating worktable rotates intermittently relative to the cabinet, sequentially marking the workpieces on the fixtures. During the intervals when the rotating worktable stops rotating, marked workpieces outside the marking chamber can be removed from the fixtures, and / or unmarked workpieces can be installed onto the fixtures. This allows the loading / unloading process and the marking process to be performed simultaneously, increasing the number of workpieces that the laser marking device with multiple tooling fixtures can mark per unit time and improving marking efficiency.
[0057] The principles and features of the embodiments of this application are described below with reference to the accompanying drawings. The examples given are only used to explain the embodiments of this application and are not intended to limit the scope of the embodiments of this application.
[0058] refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a laser marking device with multiple tooling fixtures, including a cabinet 10. The cabinet 10 defines a marking chamber 101.
[0059] The marking process can be carried out in the marking room 101. On the one hand, this can reduce laser leakage during the marking process, thereby protecting the safety of the operators; on the other hand, it can reduce the spread of smoke and dust generated during the marking process to the outside of the cabinet 10, thereby reducing pollution to the external environment of the cabinet 10.
[0060] The front side of the cabinet 10 may have a passage 102, which is connected to the marking room 101.
[0061] It should be noted that, in the embodiments of this application, "front side" refers to the side of the laser marking equipment with multiple tooling fixtures that faces the operator during normal use.
[0062] refer to Figure 1 , Figure 2 and Figure 3 The laser marking equipment with multiple tooling fixtures in this embodiment may further include a rotary table 20. The rotary table 20 may be a frustum, and the axis of the rotary table 20 may extend along the height direction Z of the laser marking equipment with multiple tooling fixtures.
[0063] The rotary worktable 20 is rotatably mounted on the cabinet 10, and the rotary worktable 20 can rotate about its own axis relative to the cabinet 10.
[0064] refer to Figure 3The rotary worktable 20 can be installed inside the passageway 102. Part of the rotary worktable 20 is located inside the marking room 101, and another part is located outside the marking room 101.
[0065] During the marking process, the operator can manually rotate the part of the rotating worktable 20 located outside the marking room 101 to make the rotating worktable 20 rotate.
[0066] In some possible implementations of the embodiments of this application, the laser marking equipment with multiple tooling fixtures may further include a driving device, which is connected to the rotary worktable 20 in a transmission manner to drive the rotary worktable 20 to rotate relative to the cabinet 10.
[0067] In some embodiments, the driving device may include a drive motor, which includes a motor body and a motor shaft. The motor shaft is connected to the motor body, and the motor body drives the motor shaft to rotate about the axis of the motor shaft. The axis of the motor shaft may be parallel to the rotation axis of the rotary table 20. The motor shaft may be fixedly connected to the rotary table 20 and drive the rotary table 20 to rotate.
[0068] In other embodiments, reference is made to Figure 3 The driving device may include a rotary cylinder 60. The rotary cylinder 60 includes a cylinder body and an output shaft. The cylinder body is kinetically connected to the output shaft and drives the output shaft to rotate. The axis of the output shaft may be parallel to the rotation axis of the rotary table 20. The output shaft may be fixedly connected to the rotary table 20 and drive the rotary table 20 to rotate.
[0069] In some possible implementations of the embodiments of this application, reference is made to Figure 1 and Figure 3 The laser marking equipment with multiple tooling fixtures may also include at least two tooling fixtures 30. The tooling fixtures 30 are set on the top of the rotary table 20. The tooling fixtures 30 are used to hold the workpiece a to reduce the movement of the workpiece a during the marking process, thereby improving the reliability of the marking results.
[0070] The embodiments of this application do not limit the specific number of tooling fixtures 30. Those skilled in the art can reasonably set the number of tooling fixtures 30 according to the specifications of the workpiece a to be marked.
[0071] For example, refer to Figure 4 The number of tooling fixtures 30 is 16 to make full use of the space on top of the rotary table 20. Before marking, all tooling fixtures 30 can assemble a total of 16 workpieces a, which increases the number of workpieces a that can be loaded before marking, reduces the time spent loading during the marking process, and improves the marking efficiency of laser marking equipment with multiple tooling fixtures.
[0072] At least two tooling fixtures 30 may include multiple groups, each group may have one or more tooling fixtures 30, and the tooling fixtures 30 in each group have the same specifications. The specifications of the tooling fixtures 30 in different groups may be different, so that the laser marking equipment with multiple tooling fixtures can mark workpieces a of multiple specifications.
[0073] refer to Figure 3 and Figure 4 At least two tooling fixtures 30 can be distributed on the rotary worktable 20 inside the marking room 101 and on the rotary worktable 20 outside the marking room 101. That is, when the rotary worktable 20 rotates, a portion of the tooling fixtures 30 is always located on the rotary worktable 20 inside the marking room 101, and the other portion of the tooling fixtures 30 is located on the rotary worktable 20 outside the marking room 101.
[0074] refer to Figure 5 The laser marking equipment with multiple tooling fixtures in this application embodiment may further include a marking machine 40, which is disposed in the marking chamber 101 and may be located above the rotary worktable 20. The marking machine 40 is used to mark the surface of workpiece a.
[0075] The laser marking equipment with multiple tooling fixtures according to this application embodiment rotates the rotary worktable 20 relative to the cabinet 10 during the marking process, and stops rotating during marking to allow the marking machine 40 to mark the workpiece a. Throughout the marking process, the rotary worktable 20 rotates intermittently relative to the cabinet 10, marking the workpiece a on the tooling fixture 30 sequentially. During the intervals when the rotary worktable 20 stops rotating, the marked workpiece a located outside the marking chamber 101 can be removed from the tooling fixture 30, and / or the unmarked workpiece a can be installed onto the tooling fixture 30, thereby allowing the loading / unloading process and the marking process to be performed simultaneously. This increases the number of workpieces a that the laser marking equipment with multiple tooling fixtures can mark per unit time, thus improving marking efficiency.
[0076] In some possible implementations of the embodiments of this application, at least two tooling fixtures 30 may include tooling fixtures 30 of various specifications. The specifications of the tooling fixtures 30 correspond to the specifications of the workpiece a to be clamped, so that multiple workpieces a of different specifications can be marked at the same time.
[0077] In some possible implementations of the embodiments of this application, the tooling fixture 30 is detachably mounted on the rotary table 20. This allows the corresponding tooling fixture 30 to be replaced according to the specifications of the workpiece a to be marked, thereby improving the versatility of the laser marking equipment with multiple tooling fixtures.
[0078] For example, refer to Figure 6 and Figure 7The tooling fixture 30 may be equipped with a first connecting hole 315. (See reference) Figure 8 The rotary table 20 may have a second connecting hole 202. The rotary table 20 and the tooling fixture 30 can be fixedly connected by fastening bolts passing through the first connecting hole 315 and the second connecting hole 202.
[0079] In other possible implementations, the top of the rotary table 20 may be provided with a insert rod, the axis of which may extend along the axis of the rotary table 20. The bottom of the tooling fixture 30 may be provided with a socket, the axis of which may extend along the axis of the rotary table 20. The insert rod may be inserted into the socket to mount the tooling fixture 30 onto the insert rod.
[0080] Each tooling fixture 30 can be constructed with multiple insertion holes, and correspondingly, the rotary table 20 can be constructed with multiple insertion rods. Each tooling fixture 30 can be inserted into multiple insertion rods to restrict the rotation of the tooling fixture 30 relative to the rotary table 20.
[0081] In some possible implementations of the embodiments of this application, reference is made to Figure 4 , Figure 6 and Figure 7 The tooling fixture 30 may be constructed with a positioning part 311 and a clamping part 312. The positioning part 311 is used to stop the workpiece a to limit the workpiece a. The clamping part 312 is used to clamp the workpiece a to reduce the possibility of the workpiece a moving.
[0082] In some embodiments, reference Figure 7 The tooling fixture 30 may include a base 310, and the top of the base 310 may be constructed with an insertion channel 313 with a top opening, and the two ends of the insertion channel 313 passing through the base 310 along its own axis.
[0083] Workpiece a can be moved downward from the top opening of insertion channel 313 into insertion channel 313 so that workpiece a passes through insertion channel 313. The channel wall 314 of insertion channel 313 forms clamping part 312. The insertion channel 313 is used to accommodate workpiece a to reduce the possibility of workpiece a moving in the horizontal direction perpendicular to the axis of insertion channel 313.
[0084] In some embodiments, an elastic fastener may be provided on the channel wall 314 of the insertion channel 313. The elastic fastener is used to elastically press against the workpiece a to clamp the workpiece a and reduce the possibility of the workpiece a shaking in the insertion channel 313.
[0085] Among some possible implementations, refer to Figure 4 and Figure 7The elastic fastener can be a spring plunger 320, the axis of which can be perpendicular to the axis of the insertion channel 313, and the axis of which can be in the horizontal direction.
[0086] The spring plunger 320 may include a plunger body 321, a spring, and a plunger head 322. The plunger body 321 passes through the channel wall 314 of the insertion channel 313. The plunger head 322 is slidably disposed on the plunger body 321 and can slide relative to the plunger body 321 along the axial direction of the plunger body 321. The plunger head 322 can move into the insertion channel 313. The spring is telescopically disposed inside the plunger body 321 and elastically connected to the plunger head 322. The spring is used to apply a spring force to the plunger head 322 after the external force on the plunger head 322 is released, so that the plunger head 322 moves away from the plunger body 321, thereby resetting the plunger head 322.
[0087] The plunger head 322 is used to abut against the workpiece a. The plunger head 322 can be round or flat to facilitate contact with the workpiece a.
[0088] The plunger head 322 can extend and retract along the axial direction of the plunger body 321, thereby clamping the workpiece a and reducing the possibility of the workpiece a swaying in the insertion channel 313.
[0089] The plunger head 322 can be made of resin, which typically has a low coefficient of friction. This helps reduce wear between the plunger head 322 and the workpiece a contact surface, thereby extending the service life of the tooling fixture 30.
[0090] In some other possible implementations, the elastic fastener can be an elastic washer, which can be disposed on the channel wall 314 of the insertion channel 313. The elastic washer is elastic. After the workpiece a is inserted into the insertion channel 313, the workpiece a compresses the elastic washer, causing the elastic washer to deform and clamp the workpiece a, reducing the possibility of the workpiece a wobbling within the insertion channel 313. After the workpiece a is removed from the insertion channel 313, the compressive force on the elastic washer is released, and the elastic washer automatically returns to its initial state.
[0091] In some possible implementations of the embodiments of this application, reference is made to Figure 4 and Figure 6 The axis of the insertion channel 313 can extend radially along the rotary table 20. In this way, after the workpiece a is inserted into the insertion channel 313, the workpiece a also extends radially along the rotary table 20. Since the axes of adjacent tooling fixtures 30 are separated by a certain central angle (such as α), the workpieces a on two adjacent tooling fixtures 30 are less likely to collide, thereby reducing the possibility of interference between multiple workpieces a.
[0092] In some possible implementations of the embodiments of this application, reference is made to Figure 4 and Figure 6 The positioning part 311 is positioned opposite to one end of the insertion channel 313 along the axial direction and spaced apart. After the workpiece a is inserted into the insertion channel 313, the positioning part 311 can stop the workpiece a at one end along the axial direction, thereby restricting the degree of freedom of the workpiece a along the axial direction of the insertion channel 313 and reducing the workpiece a from continuing to move toward the positioning part 311 along the axial direction of the insertion channel 313.
[0093] In some possible implementations of the embodiments of this application, reference is made to Figure 4 and Figure 6 The positioning part 311 is closer to the outer periphery 201 of the rotary table 20 than the clamping part 312. In this way, after the workpiece a is inserted into the insertion channel 313 from top to bottom, the workpiece a is moved radially outward along the rotary table 20 so that the workpiece a abuts against the positioning part 311. The positioning part 311 stops the workpiece a at the end away from the insertion channel 313, thereby reducing the possibility of the workpiece a moving radially outward along the rotary table 20.
[0094] In some possible implementations of the embodiments of this application, in at least two tooling fixtures 30, the projection of the axis of the insertion channel 313 in each tooling fixture 30 onto the corresponding positioning part 311, and the distance D between this projection and the axis of the rotary table 20 are equal. In other words, the distance between the center of each positioning part 311 and the axis of the rotary table 20 is equal. Thus, after each workpiece a is assembled into the corresponding tooling fixture 30, the distance between the end of each workpiece a that abuts against the positioning part 311 and the axis of the rotary table 20 is equal. This allows for sequential marking of multiple workpieces a at position b (refer to...) without moving the marking machine 40. Figure 4 The marking machine 40 marks the end of workpiece a near the positioning part 311.
[0095] In some possible implementations of the embodiments of this application, reference is made to Figure 6 At least two tooling fixtures 30 can be arranged on the rotary table 20 with equal central angles (α). During the marking process of the marking machine 40, the rotary table 20 rotates by the same angle (α) each time, so that the next tooling fixture 30 is directly opposite the marking machine 40. Multiple tooling fixtures 30 can be arranged with equal central angles, which makes it easy to control the rotation angle of the rotary table 20 during the marking process.
[0096] In some possible implementations of the embodiments of this application, reference is made to Figure 3The laser marking equipment with multiple tooling fixtures in this application embodiment may further include an angle detection device 190, which may be an optical rotation sensor or a laser rotation sensor, etc. The angle detection device 190 may be disposed on the rotary table 20, and the angle detection device 190 is used to detect the rotation angle of the rotary table 20.
[0097] In some possible implementations of the embodiments of this application, reference is made to Figure 3 The laser marking equipment with multiple tooling fixtures in this application embodiment may further include a safety light curtain 50, which is disposed within the marking chamber 101. The safety light curtain 50 may be disposed at one end of the marking chamber 101 near the access port 102. The safety light curtain 50 is disposed on the rear side of the access port 102.
[0098] refer to Figure 3 The safety light curtain 50 includes a first transmitter 501 and a first receiver 502 disposed opposite to each other. The first transmitter 501 is usually synchronized with the first receiver 502 to ensure proper alignment and detection of the light beam. The first transmitter 501 and the first receiver 502 are respectively disposed at both ends of the width direction X of the passage 102. The width direction X of the passage 102 may be consistent with the width direction X of the cabinet 10.
[0099] The first transmitter 501 can generate and emit a series of parallel beams, which are usually invisible and emitted at a certain frequency and intensity.
[0100] The first transmitter 501 emits multiple beams, forming a "light curtain" within the protected area. Any object or person entering this light curtain will block the beams.
[0101] The main function of the first receiving end 502 is to receive the light beams from the first transmitting end 501. Each light beam from the first transmitting end 501 has a corresponding receiver in the first receiving end 502. When all the light beams are received, it means that no object has entered the marking chamber 101 through the port 102.
[0102] refer to Figure 1 The laser marking equipment with multiple tooling fixtures may also include an industrial control computer 90, which is electrically connected to the safety light curtain 50 and the marking machine 40 respectively.
[0103] If an object or an operator's hand enters the marking chamber 101 through the port 102, it will partially block the light beam. The first receiver 502 will detect this change. The first receiver 502 will immediately transmit this status change to the industrial control computer 90, which will then control the marking machine 40 to stop marking, in order to reduce the safety hazard caused by objects or operators' hands accidentally entering the marking chamber 101 during the marking process.
[0104] In some possible implementations of the embodiments of this application, reference is made to Figure 1 and Figure 3 The laser marking equipment with multiple tooling fixtures may also include a through-beam safety sensor 70, which is installed on the cabinet 10 outside the marking room 101. The through-beam safety sensor 70 may be installed on the front side of the access port 102 and on the front side of the rotary table 20.
[0105] refer to Figure 1 and Figure 3 The through-beam safety sensor 70 may include a second transmitter 701 and a second receiver 702 disposed opposite to each other. The second transmitter 701 is used to emit a light beam. The second receiver 702 is used to receive the light beam from the second transmitter 701.
[0106] The arrangement direction of the second transmitter 701 and the second receiver 702 can be consistent with the width direction X of the port 102.
[0107] When the beam emitted by the second transmitter 701 is blocked by an object or the operator's hand, the second receiver 702 detects the interruption of the beam, thereby knowing whether an object or the operator's hand has moved above the rotary worktable 20 outside the marking room 101, in order to determine whether there is a loading or unloading operation.
[0108] In some possible implementations of the embodiments of this application, in the implementation where the rotary worktable 20 is connected to the drive device, the through-beam safety sensor 70 and the drive device can be electrically connected to the industrial control computer 90 respectively. The industrial control computer 90 is configured to control the drive device to stop working when the through-beam safety sensor 70 detects that the beam is blocked, so as to reduce the collision between objects moving to the top of the rotary worktable 20 outside the marking room 101 or the operator's hand and the rotating rotary worktable 20 or the tooling fixture 30 on it, thereby improving the safety of the laser marking equipment with multiple tooling fixtures.
[0109] In some possible implementations of the embodiments of this application, reference is made to Figure 5 The laser marking equipment with multiple tooling fixtures may also include a smoke processor 80. The smoke processor 80 may include an exhaust pipe 802 and a processor body 801.
[0110] The exhaust pipe 802 may have a connected smoke inlet and a smoke outlet.

[0119] The keyboard 130 can be placed on top of the drawer 120, so that when the keyboard 130 is needed, the drawer 120 can be pulled out from the cabinet 10. When the keyboard 130 is not needed, the drawer 120 can be pushed back into the cabinet 10, thereby reducing the impact of the keyboard 130 and the drawer 120 on the operator's movements.
[0120] In some possible implementations of this application, the laser marking equipment with multiple tooling fixtures may further include an air conditioner, which may be installed inside the cabinet 10.

[0121] In some possible implementations of the embodiments of this application, reference is made to Figure 1 The laser marking equipment with multiple tooling fixtures may also include a handheld scanning gun 140, which can be installed in the cabinet 10 or outside the marking room 101. After marking is completed, the marking on the workpiece a can be scanned by the handheld scanning gun 140 to check whether the marking is qualified.
[0122] The handheld scanner 140 can be electrically connected to the industrial computer 90. The handheld scanner 140 can scan the marking pattern to input the marking pattern information into the industrial computer 90 system.
[0123] In some possible implementations of the embodiments of this application, reference is made to Figure 5 The laser marking equipment with multiple tooling fixtures may also include an imaging device 150, which may be a camera or video camera or other device capable of acquiring image information.
[0124] The imaging device 150 can be installed in the cabinet 10. The imaging device 150 can be installed close to the marking machine 40. The imaging device 150 is used to acquire image information of the workpiece a and the marking on it after marking is completed.
[0125] refer to Figure 5A first guide rod 161 may be provided on the cabinet 10, and the first guide rod 161 may extend along the height direction Z of the cabinet 10. A connector 163 may be slidably provided on the first guide rod 161, and the connector 163 may slide up and down along the extension direction of the first guide rod 161. A second guide rod 162 may also be slidably passed through the connector 163. The extension direction of the second guide rod 162 may be parallel to the width direction X of the cabinet 10.
[0126] Imaging device 150 is connected to second guide rod 162. The horizontal position of imaging device 150 is adjusted by sliding second guide rod 162 relative to connector 163. The vertical position of imaging device 150 is adjusted by sliding connector 163 along first guide rod 161. Thus, the horizontal and vertical positions of imaging device 150 can be adjusted according to the acquisition requirements of imaging device 150, thereby adjusting the focal length of imaging device 150 to improve the clarity of the information acquired by imaging device 150.
[0127] The imaging device 150 can be electrically connected to the industrial control computer 90. The imaging device 150 sends the acquired workpiece a and its marking image information to the industrial control computer 90. After decoding the image information, the industrial control computer 90 displays the code and marking image of the workpiece a corresponding to the image information on the display 110 to perform quality inspection on the marking image.
