Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a laser cutting product pattern inspection device. Background Art

[0002] With the continuous application of new automotive materials and the continuous introduction of advanced design concepts to meet the market demand for lightweight and high-safety performance vehicles, manufacturing processes also need to be continuously innovated. Using high-strength steel stamping parts to manufacture car bodies is an important way to simultaneously achieve lightweight and improve collision safety. Laser cutting, as the main processing technology for high-strength stamping parts, replaces traditional trimming, punching and other processes, and can achieve the advantages of cutting complex parts. It is widely used in the processing of high-strength steel plates, reducing processing time, reducing processing costs, and improving workpiece quality.

[0003] Although all laser cutting equipment is currently equipped with functions to prevent missed cutting and detect waste, there are still problems with missed holes or waste adhesion in the actual production process. If the missed holes or waste adhesion are not identified in time on site and production is not interrupted in time, batch defects will result, especially when the products flow to downstream processes or customers, which will result in difficulties in rework or the scrapping of the vehicle.

[0004] Missed holes or waste adhesion cannot be detected, and production is not interrupted in time, resulting in batch defects, affecting downstream processes or causing risks such as abnormal noise caused by waste falling in the later stage. Summary of the invention

[0005] The purpose of the utility model is to provide a laser cutting product pattern inspection device to address the deficiencies of the above-mentioned technology, to inspect each cut product, and if the product fails the inspection, the subsequent products cannot be processed further, and production is interrupted, so that defects can be discovered in time and adjusted and optimized to prevent batch defects.

[0006] To achieve the above-mentioned purpose, the laser cutting product style inspection device involved in the utility model includes an inspection table, the inspection table is provided with a table top for placing the product to be inspected, the table top is provided with at least two part positioning pins matching the holes on the bottom surface of the product to be inspected, the table top is also provided with vertical inspection pins corresponding to the remaining holes on the bottom surface of the product to be inspected, and the table top is provided with a push-pull clamp on each side of the product to be inspected. A retractable transverse push rod is provided at the end of the push-pull clamp, the transverse push rod is parallel to the length direction of the product to be inspected, and the transverse push rod is provided with transverse inspection pins corresponding to the holes on the side of the product to be inspected.

[0007] Preferably, a proximity sensor for detecting whether the product to be inspected is placed in place is provided on the table top at a position close to the part locating pin.

[0008] Preferably, a proximity sensor for detecting whether the transverse push rod has moved into position is provided on the table top at a position close to the transverse push rod.

[0009] Preferably, a connector for connecting the proximity sensor and the laser cutting device is provided under the table top, and the connector is used for the proximity sensor to communicate with the laser cutting device to achieve an interlocking function.

[0010] Preferably, the table top is provided with an indicator light connected to the proximity sensor to quickly indicate whether the product to be tested is qualified.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. Inspect each finished product, identify defects in production in time, and inspect the product style after laser cutting 100% to ensure that the product style meets the requirements of the drawing. If the product fails the inspection, the subsequent products cannot be processed further;

[0013] 2. The inspection device interacts with the laser cutting equipment through signals. When defective products are found, the laser cutting equipment is locked and production is interrupted. Defects are found and optimized in time to avoid continued production of defective products and prevent batch defects.

[0014] 3. It is highly operable, and the operation steps are the same as the existing process, which does not affect the efficiency of the laser cutting equipment. The interlocking related signals can be connected with all laser cutting products, and it has strong compatibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 The utility model is a schematic diagram of the structure of the laser cutting product pattern inspection device when in use.

[0017] The components in the figure are numbered as follows:

[0018] Inspection table 1, product to be inspected 2, table top 3, hole 4, part locating pin 5, vertical detection pin 6, push-pull clamp 7, lateral push rod 8, lateral detection pin 9, proximity sensor 10, connector 11, indicator light 12. DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 and Figure 2As shown, a laser cutting product pattern inspection device comprises an inspection table 1, on which a table top 3 is provided for placing a product 2 to be inspected, on which at least two part locating pins 5 matching holes 4 on the bottom surface of the product 2 to be inspected are provided, on which vertical inspection pins 6 corresponding one-to-one to the remaining holes 4 on the bottom surface of the product 2 to be inspected are also provided, and on which a push-pull clamp 7 is provided on each side of the product 2 to be inspected on the table top 3, and at each end of the push-pull clamp 7 a retractable transverse push rod 8 is provided, the transverse push rod 8 being parallel to the length direction of the product 2 to be inspected, and on which transverse inspection pins 9 corresponding one-to-one to the holes 4 on the side surfaces of the product 2 to be inspected are provided.

[0021] In addition, in this embodiment, a proximity sensor 10 is provided on the table 3 near the part locating pin 5 for detecting whether the product 2 to be inspected is placed in place, and a proximity sensor 10 is provided on the table 3 near the transverse push rod 8 for detecting whether the transverse push rod 8 is moved into place. A connector 11 connecting the proximity sensor 10 and the laser cutting equipment is provided under the table 3, and an indicator light 12 connected to the proximity sensor 10 is provided on the table 3.

[0022] The laser cutting product involved in the present embodiment is U-shaped. When the present embodiment is used, the laser-cut product 2 to be inspected is first placed on the table 3 through the cooperation of the part positioning pin 5 and its own U-shaped groove bottom hole 4. At this time, the part positioning pin 5 quickly guides and positions the product 2 to be inspected, and the vertical detection pin 6 detects the U-shaped groove bottom hole 4 of the product 2 to be inspected. If the pattern of the U-shaped groove bottom hole 4 of the product 2 to be inspected is normal, the bottom of the product 2 to be inspected can normally sense the proximity sensor 10 located near it, and then operate the push-pull clamp 7 to detect the pattern of the U-shaped groove side wall hole 4 of the product 2 to be inspected. At this time, the horizontal push rod 8 will push the horizontal detection pin 9 to insert into the U-shaped groove side wall hole 4 of the product 2 to be inspected. If it can be pushed into place, the horizontal push rod 8 can normally sense the proximity sensor 10 located near it, and the proximity sensor 10 is connected to the indicator light 12 in series. If the pattern of the product 2 to be inspected is qualified, the indicator light 12 will light up, otherwise it will not light up, and the inspection of the product 2 to be inspected can be achieved.

[0023] In addition, this embodiment realizes signal communication between the proximity sensor 10 and the laser cutting device through the connector 11. Figure 2 As shown, after the laser-cut product 2 to be inspected is placed on the inspection table 1, the operator installs the subsequent cutting parts on the laser cutting fixture, leaves the safety grating and performs product style inspection according to the operating steps. After the indicator light 12 lights up, press the start button of the laser cutting equipment, and the parts to be cut can be cut. If the indicator light 12 is not on, the next part cutting cannot be started, which plays an interlocking role to prevent batch defects.

[0024] The utility model discloses a laser cutting product pattern inspection device, which inspects each product after cutting, so that production defects can be identified in time, and 100% inspects the product patterns after laser cutting to ensure that the product patterns meet the requirements of the drawings. If the product fails the inspection, the subsequent products cannot be processed further. The inspection device interacts with the laser cutting equipment by signals. When a defective product is found, the laser cutting equipment is locked and production is interrupted. The defect is discovered in time and adjusted and optimized to avoid continuing to manufacture defective products and prevent batch defects. The device has strong operability, and the operation steps are the same as the existing process, which does not affect the efficiency of the laser cutting equipment. The interlocking related signals can be connected with all laser cutting products, and the compatibility is strong.
