Description

Technical Field

[0001] This utility model relates to the field of laser printing technology, and in particular to a material fixing fixture for laser printing and a laser printing system including the same. Background Technology

[0002] When printing patterns (such as QR codes) on the flexible PET (polyethylene terephthalate) film of relay protection devices, operators need to frequently align the position of the PET film on the laser printing platform to ensure correct printing position and good printing results due to the variety of PET film sizes and the limited working area in the laser printer.

[0003] In the existing printing process, a fixture is usually designed for each PET film to be printed. When changing the PET film, the fixture needs to be changed and repositioned. This increases the workload of fixture disassembly and repositioning during production, reduces production efficiency and continuity, and increases the complexity of production management. Utility Model Content

[0004] The purpose of this invention is to provide a material fixing fixture for laser printing, which is easy to assemble, disassemble, and position.

[0005] Another objective of this invention is to provide a laser printing system including the aforementioned material fixing fixture, which is easy to assemble, disassemble, and position with a fixture.

[0006] This utility model provides a material fixing fixture for laser printing, comprising a base, a clamp, two limiting members, and a knob-type locking device. The two limiting members are fixedly connected to the base and arranged opposite to each other. The clamp can be inserted between the two limiting members to achieve combination with the base. The knob-type locking device is used to connect the base and the clamp to fix the relative position of the combined base and clamp.

[0007] By fixing two opposing limiting members on the base and fixing the relative position of the combined base and clamp with a knob-type locking device, the clamp can be easily installed and removed from the base, and can be easily positioned precisely by using the limiting members and the knob-type locking device.

[0008] In another illustrative embodiment of the material fixing fixture for laser printing, two limiting members are arranged opposite each other along a first direction, and the knob axis of the knob-type locking device is perpendicular to the first direction.

[0009] In another illustrative embodiment of the material holding fixture for laser printing, the fixture can be inserted between two limiting members along the mating direction to achieve combination with the base. Each limiting member has a guide surface at its end furthest from the base. The guide surfaces of the two limiting members face each other along a first direction perpendicular to the mating direction, and the distance between them gradually decreases along the mating direction. This facilitates the insertion of the fixture into the base.

[0010] In another illustrative embodiment of the material holding fixture for laser printing, the fixture includes a connecting seat and a material placement platform. The connecting seat is used to detachably connect to a base via a knob-type locking device. The material placement platform includes a material placement plate. The material placement plate is fixed to the connecting seat and is recessed along its thickness direction to form a material placement area. The material placement area is configured to hold material that matches its shape. This structure is simple and easy to manufacture.

[0011] In another illustrative embodiment of the material holding fixture for laser printing, the material placement table further includes a cover plate. The material placement plate includes a retaining edge. The retaining edge at least partially defines the boundary of the material placement area, and the cover plate is fixed to the retaining edge to at least partially cover the non-processed portion of the material, while exposing the processed portion of the material through a clearance portion thereon. This facilitates printing the material in the correct printing position, and the cover plate protects the material from scratches and keeps the material flat.

[0012] In another illustrative embodiment of the material fixing fixture used for laser printing, the clearance portion is a clearance hole or clearance notch. This structure is simple and easy to manufacture.

[0013] In another illustrative embodiment of the material holding fixture for laser printing, the feeding stage includes two stacked feeding plates along the thickness direction. One feeding plate is fixed to a connecting seat and partially covered by the other feeding plate, which is provided with a cover plate. This structure enables the simultaneous printing of two materials of the same shape.

[0014] In another illustrative embodiment of the material holding fixture for laser printing, the number of material placement plates is one. The material placement plate also includes at least one positioning element. The positioning element includes a set of positioning pins. The material placement plate has an array of positioning holes, and the set of positioning pins is inserted into the set of positioning holes to define the local boundary of the material placement area. By changing the positioning holes into which the positioning pins are inserted, the shape of the material placement area can be changed. This structure enables the printing of materials of different shapes in the same fixture.

[0015] In another illustrative embodiment of the material holding fixture for laser printing, the material placement plate has a notch extending along the thickness direction and corresponding to the edge of the material. This facilitates the removal of the material.

[0016] This utility model also provides a laser printing system, including a laser printer and the aforementioned material fixing fixture. The laser printer includes a laser printhead. The material fixing fixture includes a base and a clamp. The base is fixed to the printing platform of the laser printer. The clamp is detachably connected to the base and is used to support material for laser printing by the laser printhead.

[0017] This laser printing system is easy to assemble, disassemble, and position the fixture. Attached Figure Description

[0061] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings, in which the same reference numerals denote the same parts.

[0062] (As used herein, "schematic" means "serving as an instance, example, or illustration", and any diagram or embodiment described as "schematic" herein should not be construed as a more preferred or advantageous technical solution.

[0063] As used herein, terms such as "first" and "second" do not indicate the degree of importance or order, but are only used to distinguish one from another to facilitate the description of the document. For the sake of conciseness of the drawings, only the parts related to the present utility model are schematically shown in each drawing, and they do not represent the actual structure of the product. Nouns and pronouns referring to persons in this patent application are not limited to specific genders.

[0064] Figure 1 is a schematic structural diagram of a schematic embodiment of a material fixing tool for laser printing. Figure 2 is used to illustrate Figure 1 the material fixing tool shown. In this schematic embodiment, refer to Figure 1 and Figure 2 , the material fixing tool for laser printing is used to fix the material during the laser printing process, and the material is, for example, a flexible PET face mask of a relay protection device. The material fixing tool is, for example, fixed on the printing platform of the laser printer 50 and can be irradiated by the laser from the laser print head 51.

[0065] The material fixing tool includes a base 10, a clamp 20, two limiting members 30 and a knob-type locker 40.

[0066] As shown in Figure 1 , the base 10 may be in a shape of a Chinese character "ji", and the two limiting members 30 respectively abut against two sides of the base 10.

[0067] The two limiting members 30 are fixedly connected to the base 10 and arranged opposite to each other. As an exemplary illustration, the two limiting members 30 are arranged opposite to each other along the first direction D1. The clamp 20 can be inserted between the two limiting members 30 to realize the combination with the base 10. The knob-type locker 40 connects the base 10 and the clamp 20 to fix the relative positions of the combined base 10 and clamp 20. As an exemplary illustration, the knob axis X of the knob-type locker 40 is perpendicular to the first direction D1. As an illustrative example, the first direction D1 can be understood as the direction parallel to the upper surface of the base 10 in Figure 1 , and the rotation axis X is perpendicular to the upper surface of the base 10.

[0068] In specific operation, the two limiting members 30 are connected to the base 10, for example, by bolts. Before inserting the clamp 20, loosen the bolts on the limiting members 30. After inserting the clamp 20, turn the knob-type locking device 40 to the closed position to fix the base 10 and the clamp 20. Finally, tighten the bolts on the limiting members 30 to complete the installation and positioning of the clamp 20 on the base 10. When it is necessary to replace the clamp 20 and remove it, loosen the bolts on the limiting members 30, turn the knob-type locking device 40 to the open position, and remove the clamp 20 from the base 10.

[0069] By fixing two opposing limiting members 30 on the base 10 and fixing the relative position of the combined base 10 and clamp 20 by the knob-type locking device 40, the clamp 20 can be easily installed and removed from the base 10, making it easy to replace the clamp 20 and to achieve precise positioning through the limiting members 30 and the knob-type locking device 40.

[0070] During the assembly of the clamp 20 and the base 10, the clamp 20 can be inserted between the two limiting members 30 along the mating direction P to achieve assembly with the base 10. As an example, the mating direction P is perpendicular to the first direction D1. Each limiting member 30 has a guide surface 31 at its end furthest from the base 10. The guide surfaces 31 of the two limiting members 30 are arranged opposite each other along the first direction D1, and the distance between them gradually decreases along the mating direction P. This facilitates the insertion of the clamp 20 into the base 10. In this illustrative embodiment, the guide surface 31 is planar, but it is not limited to this; the guide surface 31 can also be curved.

[0071] In this illustrative embodiment, such as Figure 1 and Figure 2 As shown, the fixture 20 includes a connecting seat 21. This connecting seat 21 is, for example, a rectangular frame structure. The height of the connecting seat 21 along the direction perpendicular to the first direction D1 can be designed to vary depending on the desired laser printing effect. For example, compared to situations where the printing details are not highly detailed, a higher connecting seat 21 is designed to bring the material closer to the laser print head, thereby achieving a smaller spot size and higher laser energy density. The bottom of the connecting seat 21, parallel to the first direction D1, is used to detachably connect to the base 10 via a knob-type locking device 40.

[0072] The knob-type locking device 40 can be a common thumb-turn quick-locking device on the market. To visually illustrate how the base 10 and clamp 20 are connected via the knob-type locking device 40, Figure 3 An example is a thumb-twist type quick-locking device. For instance... Figure 3As shown, the knob-type locking device 40 includes a knob lock head 41, a locking sleeve 42, and an elastic element assembly 43. The knob lock head 41 includes a knob portion 411, a fixing portion 412, and a rotating pin 413. A first through hole 211 is provided at the bottom of the connecting seat 21, and the fixing portion 412 is inserted into the first through hole 211 and fixedly connected to the bottom of the connecting seat 21. The knob portion 411 and the rotating pin 413 are fixedly connected to each other and rotatably inserted into the fixing portion 412. The elastic element assembly 43 is disposed between the knob portion 411 and the fixing portion 412. As an example, the elastic element 43 is sleeved on the rotating pin 413, with one end abutting against the knob portion 411 and the other end abutting against the fixing portion 412. More specifically, the elastic element 43 includes a coil spring. A second through hole 11 is provided at the base 10, and the locking sleeve 42 is inserted into the second through hole 11 and fixedly connected to the base 10. The locking sleeve 42 has two opposing steel balls 421 embedded inside. The end of the rotating pin 413 has a spiral groove C. The spiral groove C consists of a vertical section and an inclined section. Figure 3 Due to the viewing angle, only the inclined section can be observed. Figure 4 From Figure 3 The vertical section of the spiral groove C is observed on the left side. During the insertion of the rotating pin 413 into the locking sleeve 42, the elastic element assembly 43 is compressed. In the unlocked position, the steel ball 421 enters the vertical section from the opening C1 of the spiral groove C. Rotating the knob 411 90° clockwise moves the rotating pin 413 to the locked position, and the steel ball 421 enters the end C2 of the spiral groove C. Thus, the knob-type locking device 40 is locked, and the clamp 20 is installed onto the base 10.

[0073] Conversely, when the knob 411 rotates 90° counterclockwise, it moves the rotating pin 413 from the locked position to the unlocked position, and the steel ball 421 exits from the inclined section of the spiral groove C to the vertical section. Under the elastic restoring force of the elastic element assembly 43, the knob 411 and the rotating pin 413 move upward, that is, in the opposite direction to the docking direction P, and the steel ball 421 disengages from the rotating pin 413. The knob-type locking device 40 is unlocked, and the clamp 20 can be removed from the base 10.

[0074] See Figure 1 and Figure 2 The fixture 20 also includes a material placement platform 23. The material placement platform 23 includes two stacked material placement plates 231 along the thickness direction T, one of which is fixed to the connecting seat 21 and partially covered by the other material placement plate 231. Each material placement plate 231 is recessed along its thickness direction T to form a material placement area M. Figure 1 and Figure 2In this embodiment, the thickness direction T is parallel to the docking direction P, but is not limited to this. A material placement area M is configured to hold material whose shape matches its dimensions. Shape matching here includes geometric matching and dimensional matching of that geometry to prevent material movement along a plane perpendicular to the thickness direction T. In this illustrative embodiment, the geometry of the material placement area M is rectangular, but is not limited to this.

[0075] Each material placement plate 231 also includes a retaining edge 2311. The retaining edge 2311 at least partially defines the boundary of the material placement area M. Figure 1 As shown, the material placement area M of each material placement plate 231 is rectangular, and its four boundaries are defined by four mutually perpendicular retaining edges 2311. Each material placement plate 231 also has a material picking notch 2312 extending along the thickness direction T at two corners (for clearer display). Figure 2 Only two material pick-up notches 2312 on one of the material placement plates 231 are shown in the diagram. These notches 2312 correspond to the edges of the material placed in the material placement area M. This facilitates the removal of the material from the material placement area M after printing, but these notches 2312 are not mandatory. In other illustrative embodiments, these notches 2312 can also be provided in other parts of the material placement plate 231; any location that corresponds to the edge of the material to facilitate material removal can be a location for providing the pick-up notches 2312.

[0076] It is important to note that Figure 1 The two material placement plates 231 in the middle have hollowed-out interiors. The purpose of this large-area hollowing-out is to reduce weight.

[0077] The material placement platform 23 also includes a cover plate 233. The cover plate 233 is fixedly mounted on... Figure 1 The upper material placement plate 231 has a retaining edge 2311 that at least partially covers the non-processed portion of the material along the thickness direction T, and exposes the processed portion of the material along the thickness direction T through a clearance notch 2333. However, this is not limited to this; the clearance notch 2333 can also be other forms of clearance, such as clearance holes, which can be adjusted according to the actual application. During printing, it should be ensured that the clearance notch 2333 falls completely within the laser beam spot area. Since the material is flexible and easily scratched and bent, the cover plate 233 not only protects the material placed in the material placement area M from scratches but also maintains the flatness of the material, ensuring good printing results.

[0078] for Figure 1 The lower material placement plate 231 is partially covered by the upper material placement plate 231, which acts as a cover plate 233, thus eliminating the need for an additional cover plate 233. From two opposite directions (i.e., from the lower material placement plate 231...) Figure 1 Feeding from the left side, with the upper material placement plate 231 feeding from... Figure 1 After the material is placed into the two feeding plates 231 via the right-side feeder, the part of the material to be processed in the lower feeding plate 231 is directly exposed to the laser beam, while the part of the material to be processed in the upper feeding plate 231 is exposed to the laser beam through the clearance notch 2333 of the cover plate 233. This makes it easy to print two materials of the same shape simultaneously in the correct printing position.

[0079] Figure 5 This is a schematic diagram illustrating another embodiment of a material fixing fixture for laser printing. Compared to Figure 1 The material fixing fixture for laser printing shown is similar to the one used in this illustrative embodiment, and the similarities will not be repeated here. Figure 1 The main difference between the laser-printed material fixing fixture shown in this illustrative embodiment is that the laser-printed material fixing fixture shown in this embodiment has only one material placement plate 231 and the shape of its material placement area M can be changed.

[0080] See Figure 5 The material placement area M of the material placement plate 231 is defined by four retaining edges 2311 along its four directions. At this point, the material placement area M is the maximum material placement area M, and the material size is also the maximum size. For materials with dimensions smaller than the maximum size, such as... Figure 5 As shown, the material only occupies a portion of the maximum material placement area M.

[0081] To redefine the material placement area M to accommodate materials smaller than the maximum size, the material placement platform 23 also includes, for example, two positioning elements 235 arranged perpendicularly to each other (for clear display of the image, Figure 5 (Only one is shown in the diagram). At this time, the boundaries of the new material placement area M in two directions are defined by two mutually perpendicular guard edges 2311, and the boundaries in the other two directions are defined by two mutually perpendicular positioning elements 235, in order to accommodate materials whose size is smaller than the maximum size.

[0082] Each positioning component 235 includes a set of positioning pins 2351 and a positioning plate 2353. The set of positioning pins 2351 passes through the positioning plate 2353. Figure 5 In the set of positioning pins 2351, there are two positioning pins 2351 (for clearer display). Figure 5 (Only one is shown in the image), but it is not limited to this; the number of locating pins 2351 can also be more than two. The material placement plate 231 has three sets of locating holes 2313, two of which are already inserted by two locating elements 235. Figure 5Only one set of positioning holes 2313 arranged along the first direction D1 is shown exposed. To change the material placement area M along the boundary perpendicular to the first direction D1, the positioning element 235 can be inserted. Figure 5 In the set of positioning holes 2313 exposed in the middle (positioning element 235 after changing position, such as...) Figure 5 (As shown by the dashed line). Therefore, by changing the positioning hole 2313 into which the positioning pin 2351 is inserted, the shape of the material placement area M can be changed. This structure enables the printing of materials of different shapes in the same fixture 20. In other illustrative embodiments, the number of positioning members 235, the number of positioning pins 2351 in each positioning member 235, the number of sets of positioning holes 2313, and the position of the positioning holes 2313 can all be flexibly adjusted according to the actual application scenario.

[0083] It is worth noting that cover plates 233 are fixed on the two retaining edges 2311 used to define the boundary of the new material placement area M. A clearance hole 2331 is provided on the cover plate 233 to expose the part of the material to be processed along the thickness direction T. This facilitates fixing the printing position, allowing materials of different sizes to be printed in the same location. Of course, the clearance hole 2331 can also be... Figure 1 The avoidance gap 2333 or other forms are shown.

[0084] This utility model also provides a laser printing system, such as Figure 2 As shown, this includes a laser printer 50 (e.g., Figure 2 (As shown in the dashed box) and the aforementioned material fixing fixture. The laser printer 50 includes a laser printhead 51 (as shown in the dashed box). Figure 2 (As shown in the dashed box). The material holding fixture includes a base 10 and a clamp 20. The base 10 is fixed to the printing platform of the laser printer 50. The clamp 20 is detachably connected to the base 10 and is used to hold the material for laser printing by the laser printhead 51. The laser printing system allows for easy assembly, disassembly, and positioning of the clamp 20.

[0085] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0086] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent implementation schemes or modifications made without departing from the spirit of the present utility model, such as combinations, divisions or repetitions of features, should be included within the scope of protection of the present utility model.
