[0023] This utility model discloses a specific implementation of a laser marking device with error-proofing function. Figure 1 to Figure 2 The automatic screw driving device includes a frame 2, a positioning jig 4, a laser marking mechanism 3, a cutting component and an error-proofing sensor 6.

[0024] In this embodiment, the top surface of the frame 2 is a work surface, and a mounting frame 20 is provided on the work surface. Specifically, the mounting frame 20 includes a left side plate 21, a right side plate 22, a back plate 23 and a top plate 24, and the back plate 23, the left side plate 21 and the right side plate 22 are all vertically fixedly installed on the top surface of the frame 2, the left side plate 21 and the right side plate 22 are respectively located on the left and right sides of the back plate 23, and the top plate 24 is covered on the top of the left side plate 21, the right side plate 22 and the back plate 23, so that an operation window is formed on the front side of the mounting frame 20, and workers can put the products to be processed into the positioning jig 4 through the operation window.

[0025] In order to improve the safety of the screw driving equipment, the front end surface of the left plate 21 and the front end surface of the right plate 22 are fixedly mounted with safety gratings 25. Specifically, the two safety gratings 25 are symmetrically arranged on the front side of the mounting frame 20. The grating safety level is level 4, and a double-circuit safety connection is adopted, which can prevent personnel from breaking into the working area during the operation of the equipment and causing safety hazards.

[0026] In this example, see Figure 2 The positioning jig 4 is fixedly mounted on the top surface of the frame 2 and is also located in the mounting frame 20. The positioning jig 4 includes a bottom plate 41, on which a plurality of spaced profiling blocks 42 are fixedly mounted. In this embodiment, there are four profiling blocks 42, which are arranged in a matrix. Figure 3 , Figure 3 Schematic diagram of the structure of the product 1 to be processed. The bottom surface of the product 1 to be processed is provided with a marking reinforcement rib 11 to be cut and discarded. The marking reinforcement rib 11 can be prepared in advance during the product production process. Since the product 1 to be processed is a curved surface structure, the supporting surface of each profiling block 42 can be set as an inclined surface. In other embodiments, the shape and structure of the profiling block 42 can be selectively designed according to the shape and structure of the product 1 to be processed.

[0027] As a further improvement, the cutting assembly is fixedly mounted on the bottom plate 41, and is used to cut the identification reinforcement rib 11 of the product 1 to be processed. Figure 2 The cutting assembly includes a cutting cylinder 51, which is provided with a rotatable output shaft, a connecting plate 52 is fixedly mounted on the end of the output shaft, and a cutter (not shown) for cutting the logo reinforcement rib 11 is fixedly mounted on the connecting plate 52. It should be noted that the shape and structure of the cutter can be selectively set according to the logo reinforcement rib 11 to be cut, and the cutter can be a blade of different shapes such as an arc shape, a straight plate shape, or a hot melt blade, as long as it can cut the logo reinforcement rib 11 on the processed product 1.

[0028] In this embodiment, the error-proofing sensor 6 is fixedly mounted on the bottom plate 41 and is used to detect the identification reinforcement rib 11 of the product to be processed 1. Specifically, the error-proofing sensor 6 is fixedly mounted on the bottom plate 41 through a mounting bracket 61, the mounting bracket 61 is fixed to the bottom plate 41, and the error-proofing sensor 6 can be mounted at any position on the mounting bracket 61, so that it is convenient to adjust the position of the error-proofing sensor 6. If the error-proofing sensor 6 detects the identification reinforcement rib 11 to be cut, it means that the product has not been processed. If the error-proofing sensor 6 does not detect the identification reinforcement rib 11 to be cut, it means that the product has been processed.

[0029] In this embodiment, a position sensor 43 for detecting the position of the product 1 to be processed is fixedly installed on the side of one of the profiling blocks 42. The position sensor 43 is mainly used to detect whether a product is placed on the positioning jig 4. In addition, in order to facilitate the pressing work of the product 1 to be processed, a pressing assembly is also fixedly installed on the bottom plate 41. Specifically, the pressing assembly includes an angle cylinder 71, and a pressing member 72 is fixedly connected to the working end of the angle cylinder 71.

[0030] In this embodiment, the laser marking mechanism 3 includes a laser generator 31 and a lifting assembly 32 that drives the laser generator 31 to reciprocate in the vertical direction. The lifting assembly 32 includes a lifting rail, a lifting slide that can slide along the lifting rail, and a driver that drives the lifting slide to slide along the lifting rail. The laser generator 31 is fixedly mounted on the lifting slide, so that the laser generator 31 can reciprocate in the height direction.

[0031] Furthermore, in order to improve the convenience of the screw driving equipment, a main switch assembly 81 is provided on the left side or right side of the rack 2, and a start switch assembly 82 is provided on the front face of the rack 2. The main switch assembly 81 adopts a switch with a lockout and tagout function to meet the safety requirements during the equipment maintenance process. In addition, an operation display panel 91 is provided in the installation frame 20, which is convenient for the operator to adjust the parameters of the equipment and observe the working status of the equipment. Furthermore, a sensor indicator panel 92 is provided in the installation frame 20, and the sensor indicator panel 92 can feedback the detection status of each sensor through lights, which is convenient for the operator to observe intuitively.

[0032] The working process of the laser marking equipment of this embodiment is as follows: at the beginning of production, the product 1 to be processed is manually placed on the positioning jig 4, the in-place sensor 43 can detect whether the product is placed in place, and the error-proofing sensor 6 can detect whether the product has the identification reinforcement rib 11 for identification and error-proofing, and then determine whether it has been laser marked before. During processing, the operator can press the start switch assembly 82 to start the equipment. When the equipment starts working, the corner cylinder 71 drives the clamping member 72 to clamp the product 1 to be processed to the specified position. Driven by the lifting assembly 32, the laser generator 31 performs laser marking according to the preset pattern and parameters. When the marking is completed, the cutting cylinder 51 of the cutting assembly starts working, driving the connecting plate 52 and the cutter to cut and remove the identification reinforcement rib 11 on the product for identification and error-proofing. After the cutting is completed, each mechanism assembly returns to its position. At this time, the product can be taken out of the equipment by the operator, and the entire process is completed.

[0033] This laser marking equipment can realize the requirement of quickly marking AIRBAG logo on products during the processing of automobile dashboards. At the same time, the error prevention and detection devices of the equipment can prevent products from being repeatedly processed and unprocessed products from flowing into the later process, thus avoiding the outflow of defective products in the production process. The equipment parameter customization function can meet the processing of different products and different patterns. One device can be used for the processing of multiple products. In the large environment of the automobile industry market where products are rapidly updated, it can greatly reduce the investment cost of subsequent projects and achieve the effect of reducing investment and lean production.

[0034] Compared with the prior art, an error-proofing sensor 6 is provided to detect the identification reinforcement rib 11 at the bottom of the product to be processed 1, so as to determine whether the product has been marked and processed; a cutting component is provided to cut the discarded identification reinforcement rib 11 at the bottom of the product to be processed 1, so as to identify the processed status of the product. This can avoid repeated processing of the product and the flow of unprocessed products into the subsequent process, and avoid the outflow of defective products in the production process. Compared with traditional punching labels, it has higher work efficiency and solves the problem of low work efficiency in the past.

[0035] Finally, it should be noted that the laser marking device with error-proofing function disclosed in the embodiment of the utility model is only a preferred embodiment of the utility model, which is only used to illustrate the technical solution of the utility model, rather than to limit it.
