Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, and in particular to a laser marking and positioning device for plastic products. Background Technology

[0002] Plastic products, mainly made of PP and PVC, are mostly semi-finished parts or products with relatively conventional structures. Their main characteristics are relatively symmetrical shapes, or cylindrical or cylindrical shapes.

[0003] Due to the different materials and varying processing ratios of plastic products, their textures also differ. In the current trend of high-quality, branded production, manufacturers require marking of both finished and semi-finished plastic products for identification. Currently, marking of plastic products can be accomplished using laser marking machines. After positioning the plastic product, the laser marking machine can mark it at the designated location.

[0004] The current problem is that plastic products are diverse, and fixing them often requires customizing multiple positioning devices for different products, which increases production costs. Therefore, the existing technology lacks a positioning device that can adapt to the shape of most plastic products, so as to reduce the additional costs incurred by making separate positioning devices. Utility Model Content

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application. It should be noted that, in the present application, in order to facilitate description, the "left side" in the current view is the "first end", the "right side" is the "second end", the "upper side" is the "first end", and the "lower side" is the "second end". The purpose of such description is to clearly express the technical solutions, and should not be understood as an improper limitation on the technical solutions of the present application.

[0049] The present application solves the technical problem that there is no positioning device that can adapt to the shapes of most plastic products in the prior art, thereby reducing the additional cost caused by separately manufacturing the positioning device. The present application provides a plastic product laser marking positioning device. Therefore, the purpose of the present technical solution is to cover as many plastic products as possible, which are relatively regular in shape and have relatively large production capacity. Such plastic products are roughly divided into two categories: geometric bodies with edges as the main body and cylinders. Please refer to the drawings shown in the specification. Figure 1

[0050] In the present technical solution, the workbench 10 is arranged with parallel rails 20. Two groups of clamping plates 30 are connected to the parallel rails 20 and can move along the parallel rails 20.

[0051] For geometric bodies with edges as the main body, most of them can be clamped. Therefore, the present technical solution uses two groups of clamping plates 30 to clamp the geometric bodies with edges as the main body in the clamping space 101. The two groups of clamping plates 30 can be locked on the workbench 10 by corresponding locking components 300 to achieve longitudinal fixation.

[0052] The auxiliary positioning rod 40 is perpendicularly screwed on the clamping plate 30. The auxiliary positioning rod 40 abuts against the geometric body with edges as the main body to achieve partial abutment fixation and complete the laser marking work.

[0053] For cylindrical plastic products, the first end of the clamping plate 30 is used to construct a V-shaped limiting space 201. The radial direction of the cylindrical plastic product is supported by the clamping plate 30. The V-shaped limiting space 201 forms two contact points with the cylindrical plastic product. In cooperation with the self-weight of the plastic product, it is sufficient to complete the general marking work.

[0054] ​In summary, the technical scheme has the advantages that most plastic products can be stably fixed, that is, clamping function is provided, and stable support is achieved, so that the number of separately manufactured marking positioning tools can be greatly reduced, thereby saving production cost.

[0055] In a specific embodiment, as shown in Figure 1 、 2 , the V-shaped limiting space 201 formed at the first end of the clamping plate 30 is formed by the inclined edge 301 and the bottom groove 302.

[0056] The bottom groove 302 is provided with a locking threaded hole 31;

[0057] The workbench 10 is provided with a plurality of positioning threaded holes 32 along the center of the length direction of the workbench 10;

[0058] The locking component 300 is a positioning screw 33, which can be screwed into the locking threaded hole 31 and the positioning threaded hole 32;

[0059] The positioning screw 33 has a nut end.

[0060] For cylindrical plastic products, in a specific embodiment, as shown in Figures 1-4 , a rubber pad strip 303 is arranged on the inclined edge 301, so as to increase the radial friction.

[0061] For geometric bodies with edges as the main body, in a specific embodiment, as shown in Figure 1 、 2 , 3, the clamping plate 30 has a clamping plate piece part 310; the clamping plate piece part 310 is provided with an auxiliary positioning threaded hole 320; an auxiliary positioning rod 40 is screwed into the auxiliary positioning threaded hole 320; the auxiliary positioning rod 40 has an operating handle 42 and a positioning head 41, and the abutting is achieved by the positioning head 41.

[0062] For the adjustment of the clamping distance, in a specific embodiment, as shown in Figure 1 、 2 , 3, the lower end of each clamping plate piece part 310 is fixedly connected with a rail matching part 21, the rail matching part 21 is provided with a rail groove 22, the rail groove 22 is used to form rail connection with the rail of the parallel rail 20; the two ends of the rail are provided with a blocking block 23.

[0063] For cylindrical plastic products, in a specific embodiment, as shown in Figure 3 、 4 , if the plastic product is very light and difficult to be stably maintained by the V-shaped limiting space 201, an auxiliary fixing part 50 can be configured and arranged on both sides of the workbench 10.

[0064] When the V-shaped limiting space 201 formed by the first end of the clamping plate 30 is used to support the cylindrical plastic product, the auxiliary fixing member 50 can extend radially to the locating end 51 of the cylindrical plastic product.

[0065] The auxiliary fixing member 50 comprises a fixed support 501, the first end of which is vertically connected with an extension 502; the extension 502 is provided with an action cylinder 503, the output end of which is perpendicular to the horizontal plane; the locating end 51 is arranged on the output end of the action cylinder 503; the locating end 51 is configured in a U shape, so that the locating end 51 can also form two horizontally downward force fixing points on the cylindrical plastic product, so as to ensure the stability of the cylindrical plastic product due to the light weight.

[0066] Obviously, the above embodiments are only examples for clearly illustrating the present application, and are not intended to limit the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
