TECHNICAL FIELD

[0001] The application relates to the technical field of laser marking equipment, in particular to titanium alloy product laser marking sample preparation equipment. BACKGROUND

[0002] Titanium alloy is widely used in high-end manufacturing due to its excellent performance, and permanent marking on the surface of the titanium alloy is crucial for product traceability. Laser marking is the mainstream marking technology, but in actual production, when the surface of the titanium alloy is coated with functional coatings such as aluminum or molybdenum disulfide, the process difficulty is significantly increased.

[0003] The core problem is that the selection of laser marking parameters is extremely critical. If the parameters are not set properly, clear and firm marks cannot be formed on the coating surface. This defect is not easy to detect on single-piece products. Once incorrect parameters are used in batch production, the marks of the entire batch of products will be blurred or incomplete, causing product information to be unidentifiable, and ultimately leading to the serious consequence of the entire batch being scrapped, resulting in huge economic losses for the enterprise.

[0004] Therefore, in order to realize the experimental adjustment of the laser marking parameters during the processing of the titanium alloy, the titanium alloy product laser marking sample preparation equipment is proposed. SUMMARY

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application.

[0020] Reference Figures 1-7As an embodiment of the present invention, a laser marking sample preparation device for titanium alloy products is disclosed. Specifically, the sample preparation device includes a machine base 1 and a laser unit 2, a feeding unit 3, a transfer unit 4 and a sample collection unit 5 installed on the machine base 1. The feeding unit 3 includes a support frame 31 fixedly installed on the machine base 1. A hopper assembly 32 is fixedly installed above the support frame 31 and a feeding plate 33 located below the hopper assembly 32 is slidably connected. A pusher 34 that drives the feeding plate 33 to reciprocate is also installed above the support frame 31. Optionally, in this embodiment, the pusher 34 can be set as a cylinder, which is fixed on the support frame 31 and its shaft end is connected and fixed to the feeding plate 33. The transfer unit 4 is used to transfer the processed sample from the feeding plate 33 to the sample collection unit 5.

[0021] In other words, in this invention, the sample is continuously conveyed by the feeding unit 3, and the laser unit 2 marks it sequentially using different parameters. Then, the transfer unit 4 transfers the processed sample to the sample collection unit 5. All samples undergo uniform surface post-treatment, and the group with the clearest marking can be selected by intuitive comparison. Based on this, the optimal marking parameters of the laser unit 2 are solidified, avoiding blind trial and error on the formal product. This fundamentally eliminates the problem of large-scale scrapping caused by improper parameters and effectively solves the problem of unclear marking on the titanium alloy surface coating.

[0022] In some embodiments, the hopper assembly 32 of the present invention includes; The hopper 321 is fixedly installed above the support frame 31 by the upright plate 320. There is a slide between the upper end of the hopper 321 and the support frame 31. The upper and lower ends of the hopper 321 are open. The feeding plate 33 slides in the slide and is located on the lower side of the hopper 321.

[0023] Furthermore, in this embodiment of the invention, a hopper cover 322 is fixedly installed above the hopper 321 by fasteners, and a compression spring 323 is fixedly installed on the inner side of the hopper cover 322. The compression spring 323 is used to press and compress the sample.

[0024] In other words, before work, multiple samples can be placed into the hopper 321 at once, and then the hopper cover 322 can be closed. The fastener described in this embodiment of the invention is provided with bolts, which are threaded to the hopper cover 322 and pass through the hopper 321, so as to fix the hopper cover 322. Once the cover 322 is fixed, the pressure of the compression spring 323 is used to press multiple samples downwards, allowing them to be sequentially fed into the receiving groove 331.

[0025] Based on the above embodiments, in this embodiment of the invention, a receiving groove 331 is formed on the end face of the feeding plate 33, and two positioning bevels 332 are also formed in the receiving groove 331. The receiving groove 331 is used to receive the above-mentioned sample, and the positioning bevels 332 are used to center and position the sample.

[0026] When the material is actually being fed, when the pusher 34 drives the feeding plate 33 to move backward, when the receiving groove 331 on the feeding plate 33 moves to below the hopper 321, the sample moves downward under the contact of the compression spring 323 and falls into the receiving groove 331. Afterwards, the pusher 34 drives the feeder plate 33 forward until it moves below the laser unit 2, at which point the laser marking operation can be performed. At this time, the upper side of the feeder plate 33 stops the bottom of the hopper 321 to prevent the sample from falling further. After the marking is completed, the pusher 34 further drives the feeder plate 33 forward, and then the transfer unit 4 can place the marked sample into the sample collection unit 5. Then the feeding plate 33 is reset, and this process is repeated to achieve continuous feeding and marking of multiple samples.

[0027] In some embodiments, the outer side of the feeding plate 33 of the present invention is provided with an opening groove 333 that communicates with the receiving groove 331, and an abutment component 35 that slides in the opening groove 333 is also provided on the outer side of the upright plate 320. The abutment component 35 is used to clamp and position the sample placed in the receiving groove 331. Together with the positioning inclined edge 332, it ensures the centering positioning capability of the sample, thereby improving the stability and reliability of subsequent laser marking operations.

[0028] In an optional embodiment, the abutment component 35 of the present invention includes; Two sleeves 351 are installed on the end faces of the two upright plates 320. A U-shaped rod 352 is movably inserted between the two sleeves 351. A tension spring 353 is fixedly connected between the end of the U-shaped rod 352 and the sleeve 351. An abutment rod 354 that slides in the opening groove 333 is fixedly installed on the upper side of the U-shaped rod 352.

[0029] Furthermore, a guide frame 355 is fixedly installed on the outer side of the upright plate 320 in this invention. A groove 356 is provided on the end face of the guide frame 355. The sleeve 351 is slidably connected in the groove 356. A compression spring 357 is fixedly connected between the guide frame 355 and the sleeve 351. A drive shaft 358 is installed on the side of the sleeve 351. A wedge block 359 that abuts against the drive shaft 358 is fixedly installed on the bottom of the feeding plate 33.

[0030] Specifically, during the feeding operation, when the receiving groove 331 of the feeding plate 33 is located in the material bin 321 to pick up the sample, the abutment rod 354 on the U-shaped rod 352 separates from the opening groove 333. After the sample is picked up, the feeding plate 33 moves forward to send the sample under the laser unit 2. During this process, the feeding plate 33 moves forward and the opening slot 333 on its front side will abut against the abutting rod 354. The abutting rod 354 slides in the opening slot 333 and presses against the sample in the receiving slot 331. With the cooperation of the positioning inclined side 332, the centering and positioning operation of the sample can be realized. After the laser marking operation is completed, the feeding plate 33 needs to move forward further to the side of the transfer unit 4. During this process, the wedge block 359 on the lower side of the feeding plate 33 will abut against the drive shaft 358 on the side of the sleeve 351, thereby driving the sleeve 351 to move downward. When the sleeve 351 moves downward, it will drive the abutment rod 354 to move downward until the abutment rod 354 separates from the inside of the opening slot 333. After separation, the abutment rod 354 is reset under the action of the tension spring 353 to wait for the next clamping operation. Since the sample has moved to the transfer unit 4 and disengaged from the abutment rod 354, there is no clamping force at this time, and the transfer unit 4 can easily remove it from the inside of the receiving groove 331, thereby improving the convenience and reliability of transfer and unloading.

[0031] In some embodiments, the transfer unit 4 of the present invention includes; A fixed platform 41 is fixedly installed on the machine base 1. A transverse cylinder 42 is fixedly installed above the fixed platform 41. A cylinder seat 43 is fixedly installed on the shaft end of the transverse cylinder 42. A lifting cylinder 44 is fixedly installed on the end face of the cylinder seat 43. A suction cup assembly 45 is fixedly installed on the shaft end of the lifting cylinder 44.

[0032] Of course, both the transverse cylinder 42 and the lifting cylinder 44 described in this embodiment of the invention are equipped with multi-axis cylinders. The suction cup assembly 45 is used to connect to the vacuum equipment. When transferring and unloading materials, the transverse cylinder 42 controls the lateral position of the suction cup assembly 45, and then the lifting cylinder 44 drives the suction cup assembly 45 to move up and down to realize the sample picking operation.

[0033] Furthermore, the sample collection unit 5 in this embodiment of the invention includes; A support platform 51 is installed above the machine base 1. A sample box 52 is detachably connected to the top of the support platform 51. Several sample placement slots are opened on the end face of the sample box 52. After the suction cup assembly 45 picks up the sample, the lateral position of the suction cup assembly 45 is controlled by the horizontal movement cylinder 42. Then, the lifting cylinder 44 drives the suction cup assembly 45 to move up and down, so that each sample can be placed into the sample placement slot in turn. In this way, the centralized feeding and collection of samples can be completed. In addition, the sample box 52 in this invention can be detachably connected to the support platform 51 by fasteners such as bolts.

[0034] It should be noted that the laser unit 2 in this embodiment of the invention includes a lifting module 21 fixedly installed on the machine base 1. A laser head 22 is fixedly installed on the slide of the lifting module 21. Optionally, the lifting module 21 in this embodiment can adopt a lead screw module structure to adjust the height of the laser head 22. Its structure and principle are conventional methods for those skilled in the art and will not be described in detail here.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
