Technical Field

[0001] This invention relates to the field of marking equipment technology, specifically to an automatic laser marking device. Background Technology

[0002] The loudspeaker is mainly composed of a bracket, voice coil, diaphragm and magnetic circuit. Its assembly process is disclosed in the earlier application with patent number CN202111150846.X, which discloses a loudspeaker single unit assembly production line and its assembly method. The assembly process is automated by combining multiple workstations. Currently, the loudspeaker still needs to be marked with a QR code. It is difficult to add such a code on such equipment. Usually, a separate marking device is used for marking, which is inefficient. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic laser marking device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: an automatic laser marking device, comprising: The conveying unit includes a recessed feeding channel for conveying tooling containing products. A support unit is provided on the conveying unit, and the support unit is provided with a first opening and a second opening arranged in parallel. The first opening and the second opening are located above the feeding channel, and the first opening and the second opening can allow a single tool to pass through. A transport unit is installed on a support unit. The transport unit includes a shifting module, a connecting module, and a clamping module. The shifting module drives the connecting module to make vertical and horizontal linear displacements. The clamping module is installed on the connecting module and can pass through the first opening and the second opening to clamp the tooling. The marking unit includes a machine body, a transfer module mounted on the machine body, and a laser marking module. The transfer module is used to accommodate a single tooling and can drive the tooling to make a horizontal linear displacement. The laser marking module is used to laser-engrave a QR code on the product within the tooling.

[0005] Furthermore, the support unit includes a base plate, the first opening and the second opening are disposed on the base plate, and two parallel guide rails are disposed below the base plate. The guide rails extend to the feeding channel, and a track for a single tooling to pass through is formed between the two guide rails. The ends of the guide rails extend below the first opening.

[0006] Furthermore, the end of the guide rail plate is provided with an inwardly recessed clearance groove, which allows the clamping module to pass through.

[0007] Furthermore, a baffle plate is provided below the substrate, the baffle plate is located between the first opening and the second opening, and a contact sensor is provided on the baffle plate.

[0008] Furthermore, the base plate and the guide rail plate are connected by a locking assembly, which includes a locking block and a locking rod. One end of the locking rod passes through the locking block, and the other end is connected to the guide rail plate. The locking block is connected to the base plate.

[0009] Furthermore, the locking block includes a U-shaped body with a connecting hole inside for the locking rod to pass through. The two ends of the U-shaped body are provided with locking holes, which allow fasteners to pass through and thereby reduce the size of the connecting hole.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example 1 like Figures 1-4 In this embodiment, the automatic laser marking equipment is mainly composed of a conveying unit 10, a support unit 20 set on the conveying unit 10, a transport unit 30 set on the support unit 20, and a marking unit 40. The conveying unit 10 includes a recessed feeding channel 11, which is used to convey tooling containing products and can be an existing belt conveyor structure.

[0017] The support unit 20 includes a substrate 21. The first opening 201 and the second opening 202 are disposed on the substrate 21. The positions of the first opening 201 and the second opening 202 are located above the feeding channel 11. The first opening 201 and the second opening 202 can allow a single tooling to pass through.

[0018] Meanwhile, two parallel guide rails 22 are provided below the substrate 21. The guide rails 22 extend to the feeding channel 11, and a track for a single tool to pass through is formed between the two guide rails 22. The ends of the guide rails 22 extend below the first opening 201.

[0019] Furthermore, a baffle plate 23 is provided below the substrate 21, the baffle plate 23 is located between the first opening 201 and the second opening 202, and a contact sensor is provided on the baffle plate 23.

[0020] Furthermore, the base plate 21 and the guide rail plate 22 are connected by a locking assembly, which includes a locking block 50 and a locking rod 60. One end of the locking rod 60 passes through the locking block 50, and the other end is connected to the guide rail plate 22 by a screw. The locking block 50 is connected to the base plate 21. The locking block 50 includes a U-shaped body 51. The U-shaped body 51 has a connecting hole 52 inside for the locking rod 60 to pass through. The two arms of the U-shaped body 51 are provided with locking holes 53. The locking holes 53 allow fasteners to pass through and thereby slightly reduce the size of the connecting hole 52, thereby clamping the locking rod 60. The two arms of the U-shaped body 51 are provided with connecting blocks 54, which are connected to the base plate 21 by screws.

[0021] Furthermore, the handling unit 30 includes a shifting module 31, a connecting module 32, and a clamping module 33. The shifting module 31 drives the connecting module 32 to make linear displacements in the vertical and horizontal directions. The two clamping modules 33 are set on the connecting module 32 and can be inserted into the first opening 201 and the second opening 202 respectively for clamping the tooling. The shifting module 31 is a linear module that realizes linear displacement in the X and Y axis directions. The connecting module 32 is a frame structure with a clamping module 33 set at each end. The clamping modules 33 are implemented using pneumatic grippers.

[0022] Correspondingly, the end of the guide rail plate 22 is provided with an inwardly recessed relief groove 221, which is for the clamping module 33 to pass through.

[0023] The marking unit 40 includes a body 41, a transfer module 42 mounted on the body 41, and a laser marking module 43. The transfer module 42 is used to accommodate a single tooling and can drive the tooling to make a linear displacement in the horizontal direction. The transfer module 42 adopts multiple linear modules to achieve linear displacement in the X and Y axes. The laser marking module 43 is a laser marking head used to laser-engrave QR codes on the products in the tooling.

[0024] In use, the tooling moves along the feeding channel 11 into the tracks of the two guide rails 22 until it reaches the position of the baffle plate 23. The tooling stops moving, and after the contact sensor is triggered, the conveying unit 30 works. The clamping module 33 moves to the clearance groove 221 to clamp it and transport it to the transfer module 42. The transfer module 42 moves to the bottom of the laser marking module 43 to perform marking. At the same time, the next tooling moves to the position of the baffle plate 23. After clamping the marked tooling, the clamping module 33 moves to the second opening 202 and releases it. The tooling continues to be conveyed along the production line. At the same time, another clamping module clamps the next tooling in the first opening 201 and repeats the above steps.

[0025] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
