Description

Technical Field

[0001] The present invention relates to the technical field of keyboard printing, and in particular to a keyboard printing and drying device. Background Art

[0002] With the progress of computer technology, computers have become an essential tool for people's work and life with their unique functions and powerful working capabilities. The keyboard is one of the hardware accessories of a computer, and its function is to input the control information of text information into the computer.

[0003] A conventional computer keyboard consists of multiple keys, and letter markings are set on the surface of the keys so that users can clearly know the information input by each key. During keyboard processing, the letter markings are generally printed on the keys by printing, and then the printing ink is applied. When printing, since the ink is all liquid, when the ink adheres to the keyboard keys, it is relatively wet. At this time, it is necessary to immediately dry the keyboard to accelerate the solidification of the ink. In the prior art, the printing and drying processes of the keyboard are usually separated. After the printing process is completed, it needs to be transported to the drying process, which easily causes the ink to deform and separate due to bumps or vibrations during transportation, affecting the factory yield rate of the keyboard. There is also an integrated printing and drying production line in the prior art. This method is similar to an assembly line, so that the staff needs to place the product at one end. After the product is printed and dried, it needs to be moved to the other end of the production line to take down the product. This causes the staff to keep going back and forth, bringing a greater working intensity to the staff, and adopting a two-person system will increase the labor cost.

[0004] Therefore, it is urgent to design a keyboard printing and drying device to overcome the deficiencies of the prior art. Summary of the Invention

[0029] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation mode of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] As Figures 1-9As shown in the figure, the present invention provides a keyboard printing and drying device, which is characterized in that it includes: a workbench 10, a printing mechanism 20 is provided in the middle of the workbench 10, a first feeding mechanism 30 and a second feeding mechanism 40 are provided on the side of the workbench 10 and arranged around the printing mechanism 20. The first feeding mechanism 30 and the second feeding mechanism 40 correspond to each other at the head and tail. A first drying mechanism 50 and a second drying mechanism 51 are respectively provided at the ends of the first feeding mechanism 30 and the second feeding mechanism 40 that correspond to each other at the head and tail; the printing mechanism 20 includes a lifting table 23. A character printing device 21 is slidably provided on one side of the lifting table 23 facing the first feeding mechanism 30. An ink printing device 22 is provided on the side of the lifting table 23 opposite to the side where the character printing device 21 is provided. The ink printing device 22 faces the second feeding mechanism 40. The first feeding mechanism 30 sequentially transports the product to the character printing device 21 and the first drying mechanism 50 for character printing and drying. The second feeding mechanism 40 sequentially transports the product located in the first drying mechanism 50 to the ink printing device 22 and the second drying mechanism 51 for ink printing and drying. Specifically, the workbench 10 is rectangular. The printing mechanism 20 is arranged at the center of the work. The first feeding mechanism 30 is arranged around the printing mechanism 20 on one side of the printing mechanism 20, and the second feeding mechanism 40 is arranged around the printing mechanism 20 on the other side, so that the tail of the first feeding mechanism 30 corresponds to the head of the second feeding mechanism 40, and the tail of the second feeding mechanism 40 corresponds to the head of the first feeding mechanism 30. Among them, the printing mechanism 20 includes a character printing device 21 and an ink printing device 22, and both the character printing device 21 and the ink printing device 22 are slidably arranged on the opposite sides of the lifting table 23 and can move up and down on the lifting table 23. The character printing device 21 corresponds to the first feeding mechanism 30, and the ink printing device 22 corresponds to the second feeding mechanism 40. When the staff places the product on the first feeding mechanism 30, the first feeding mechanism 30 transports the product to the working area of the character printing device 21. The character printing device 21 descends and prints the character ink on the product. Then the character printing device 21 ascends. The first feeding mechanism 30 transports the product with printed characters to the first drying mechanism 50 located in the conveying direction of the first feeding mechanism 30 for drying. After the drying is completed, the second feeding mechanism 40 takes over the product, and the first feeding mechanism 30 returns to its original position. The second feeding mechanism 40 transports the product after the first drying process to the working area of the ink printing device 22. The ink printing device 22 descends and prints the ink for protecting the characters on the product. Then the ink printing device 22 ascends. The second feeding mechanism 40 transports the product to the second drying mechanism 51 for the second drying to accelerate the curing of the ink. Finally, the first feeding mechanism 30 moves into the second drying mechanism 51 to take over the finished product and convey it out. The staff takes down the product to complete the steps of character printing - drying - ink printing - drying of the product.

[0031] It can be understood that by arranging the printing mechanism 20 in the middle of the workbench 10, and arranging the first feeding mechanism 30 and the second feeding mechanism 40 around the printing mechanism 20, the transportation and printing of products are realized. At the same time, the head and tail of the first feeding mechanism 30 and the second feeding mechanism 40 are connected end to end to realize that the transportation of products is both the starting point and the ending point. The staff only needs to stand at the starting point to place the products, thus reducing the labor intensity of the staff, and at the same time reducing the manual arrangement and labor costs.

[0032] Furthermore, in this embodiment, the character printing device 21 includes: a horizontally arranged character lifting frame 211, a character printing plate 212, a character scraping knife 213, and a character oil-return scraping knife 214; the character lifting frame 211 is slidably arranged on one side of the lifting table 23 through screw drive. Below both ends of the character lifting frame 211, character brush plate clamping arms 215 are respectively connected. The character printing plate 212 is arranged between the two character brush plate clamping arms 215 and is respectively connected to the corresponding character brush plate clamping arms 215 at both ends. A first scraping knife support 216 is slidably arranged horizontally on the character lifting frame 211. The character scraping knife 213 and the character oil-return scraping knife 214 are respectively fixed under the first scraping knife support 216. The character scraping knife 213 and the character oil-return scraping knife 214 both correspond to the character printing plate 212. Specifically, the lifting frame is horizontally arranged and is slidably arranged on the lifting table 23 and can slide vertically along the lifting table 23. The character brush plate clamping arms 215 are used to clamp the character printing plate 212 and press the character printing plate 212 by means of bolts, etc. The first scraping knife support 216 can slide horizontally along the character lifting frame 211 and is used to drive the character scraping knife 213 and the character oil-return scraping knife 214 to slide. Among them, the character scraping knife 213 and the character ink scraping knife 223 can both perform lifting movements on the first scraping knife support 216 through cylinders. When the character printing device 21 senses that the product is in the working area, the character lifting frame 211 descends through the work of the screw to drive the character printing plate 212 thereon to descend and stick to the surface of the product, and the product is lifted by the character brush plate clamping arms 215. Subsequently, the first scraping knife support 216 slides along the character lifting frame 211 to drive the character scraping knife 213 and the character oil-return scraping knife 214 to slide. At this time, the character scraping knife 213 sinks and contacts the character printing plate 212, and the character ink on the character printing plate 212 is printed on the surface of the product. Subsequently, the first scraping knife support 216 returns to its original position. At this time, the character scraping knife 213 rises, and the character oil-return scraping knife 214 sinks and contacts the character printing plate 212 to re-coat the character ink on the character printing plate 212 for subsequent printing.

[0033] Further, in this embodiment, the ink printing device 22 includes a horizontally arranged ink lifting frame 221, an ink printing plate 222, an ink scraper 223, and an ink return scraper 224. The ink lifting frame 221 is slidably arranged on one side of the lifting table 23 through screw drive. Below the two ends of the ink lifting frame 221, there are respectively connected ink brush plate clamping arms 225. The ink printing plate 222 is arranged between the two ink brush plate clamping arms 225 and is respectively connected to the corresponding ink brush plate clamping arms 225 at both ends. A second scraper support 226 is slidably arranged horizontally on the ink lifting frame 221. The ink scraper 223 and the ink return scraper 224 are respectively fixed below the second scraper support 226. The ink scraper 223 and the ink return scraper 224 both correspond to the ink printing plate 222. Specifically, the working principle of the ink printing device 22 is the same as that of the character printing device 21.

[0034] Further, in this embodiment, the first feeding mechanism 30 includes a first longitudinal guide rail 31 arranged along the width direction of the workbench 10 and located at one end of the workbench 10. A first longitudinal supporting fixture 32 is slidably arranged on the first longitudinal guide rail 31. A first transverse guide rail 33 is arranged along the length direction of the workbench 10. A first transverse supporting fixture 34 is slidably arranged on the first transverse guide rail 33. One end of the first longitudinal supporting fixture 32 corresponds to one end of the first transverse supporting fixture 34. Specifically, the first longitudinal guide rail 31 and the first transverse guide rail 33 are placed in an L shape as a whole. One end of the first longitudinal guide rail 31 and one adjacent end of the first transverse guide rail 33 are arranged at intervals. The first longitudinal guide rail 31 is provided with a first longitudinal supporting fixture 32 that slides along the first longitudinal guide rail 31 for supporting the product. The first transverse guide rail 33 is provided with a first transverse supporting fixture 34 that slides along the first transverse guide rail 33 for supporting the product. Both the first longitudinal supporting fixture 32 and the first transverse supporting fixture 34 can be lifted and lowered. Thus, when the product on the first longitudinal fixture needs to be transferred to the first transverse fixture, it can be transferred through the height difference. Since the first transverse supporting fixture 34 and the first longitudinal supporting fixture 32 are at the same horizontal position during transportation, when transfer is required, at this time, the first transverse supporting fixture 34 can lower its height. At this time, the first transverse supporting fixture 34 can move below the first longitudinal supporting fixture 32 to lift and transport the product. When transporting, the first transverse supporting fixture 34 can rise back to its original position, thereby avoiding conflicts between the first longitudinal supporting fixture 32 and the first transverse supporting fixture 34 due to the same height.

[0035] Further, in this embodiment, the second feeding mechanism 40 includes: a second longitudinal guide rail 41 disposed along the width direction of the workbench 10, and a second longitudinal supporting jig 42 is slidably provided on the second longitudinal guide rail 41; a second transverse guide rail 43 disposed along the length direction of the workbench 10, and a second transverse supporting jig 44 is slidably provided on the second transverse guide rail 43. One end of the first longitudinal supporting jig 32 corresponds to one end of the first transverse supporting jig 34. The other end of the second longitudinal guide rail 41 corresponds to the end of the first transverse guide rail 33 away from the first longitudinal guide rail 31, and the other end of the second transverse guide rail 43 corresponds to the end of the first longitudinal guide rail 31 away from the first transverse guide rail 33. Specifically, the second feeding mechanism 40 is arranged in the same way as the first feeding mechanism 30 and has the same working principle. At the same time, the second longitudinal guide rail 41 is adjacent to the first transverse guide rail 33, and the second transverse guide rail 43 is adjacent to the first longitudinal guide rail 31, which is convenient for transferring the products on the first conveying mechanism to the second conveying mechanism.

[0036] Further, in this embodiment, the first longitudinal supporting jig 32 includes: a longitudinal sliding seat 321 and a supporting plate 322; an extension portion 323 extending horizontally in the direction of the first transverse guide rail 33 is provided at one end of the longitudinal sliding seat 321 away from the first transverse guide rail 33. The extension portion 323 and the longitudinal sliding seat 321 form an L shape. A raised longitudinal positioning point 324 is provided at one end of the extension portion 323 away from the longitudinal sliding seat 321. At both ends of the side of the longitudinal sliding seat 321 away from the extension portion 323, the raised longitudinal positioning points 324 are respectively provided; the supporting plate 322 is rectangular, and longitudinal positioning holes 325 corresponding to the longitudinal positioning points 324 are respectively provided at the four corners of the supporting plate 322. Specifically, the longitudinal sliding seat 321 can be lifted and lowered by a cylinder. An extension portion 323 extending horizontally in the direction of the first transverse guide rail s33 is provided at one end of the longitudinal sliding seat 321 facing away from the first transverse guide rail 33. The extension portion 323 is integrally formed with the longitudinal sliding seat 321, so that the longitudinal sliding seat 321 as a whole is in an L shape, which is convenient for lifting the supporting plate 322 to prevent the supporting plate 322 from falling due to the center of gravity shifting caused by one end not being supported. At the same time, to prevent the supporting plate 322 from moving on the longitudinal sliding seat 321, at least three raised longitudinal positioning points 324 are provided on the longitudinal sliding seat 321. The three longitudinal positioning points 324 are respectively located at both ends of the side of the longitudinal sliding seat 321 away from the extension portion 323 and one end of the extension portion 323 away from the longitudinal sliding seat 321 to form a triangle. Longitudinal positioning holes 325 matching the longitudinal positioning points 324 are provided on the supporting plate 322. When the supporting plate 322 is placed on the longitudinal sliding seat 321, the longitudinal positioning points 324 are embedded in the longitudinal positioning holes 325, thereby fixing the position of the supporting plate 322 on the longitudinal sliding seat 321.

[0037] It should be noted that the second longitudinal supporting fixture 42 has the same structure and principle as the first longitudinal supporting fixture 32, so it will not be elaborated here.

[0038] Furthermore, in this embodiment, the first transverse supporting fixture 34 includes: a transverse sliding seat 341; there are two transverse sliding seats 341, and the two transverse sliding seats 341 are arranged at intervals. The two transverse sliding seats 341 are connected together by a slider 342. The slider 342 is slidably connected to the first transverse guide rail 33. At both ends of the transverse sliding seat 341 in the length direction, there are protruding transverse positioning points 343. In the middle of the support plate 322, there are transverse positioning holes 344 adapted to the transverse positioning points 343. Specifically, there are two transverse sliding seats 341, and the two transverse sliding seats 341 are arranged at intervals on the first transverse guide rail 33 and are connected together by a slider 342. Thus, when one transverse sliding seat 341 moves, the other moves synchronously. The transverse sliding seat 341 is rectangular, and at both ends of the transverse sliding seat 341 in the length direction, there are protruding transverse positioning points 343. In the middle of the support plate 322, there are two transverse positioning holes 344 adapted to the transverse positioning points 343. By cooperating with each other, the support plate 322 is fixed. When transferring the product on the first longitudinal supporting fixture 32 to the first transverse supporting fixture 34, the first longitudinal supporting fixture 32 rises to form a height difference with the first transverse supporting fixture 34, so that the first transverse supporting fixture 34 can extend into the included angle between the longitudinal sliding seat 321 and the extension part 323. Subsequently, the first longitudinal supporting fixture 32 descends, and the transverse positioning points 343 on the transverse sliding seat 341 are inserted into the transverse positioning holes 344. Then the transverse sliding seat 341 rises to lift the product and move it out of the supporting range of the longitudinal sliding seat 321. When moving to the working range of the printing mechanism 20, the product is lifted by the printing mechanism 20. At this time, the transverse sliding seat 341 moves back so that the transverse sliding seat 341 adjacent to the first drying mechanism 50 is located in the working area of the printing mechanism 20. After the printing mechanism 20 finishes printing, the product is put down. At this time, the transverse sliding seat 341 moves to convey the printed product into the first drying mechanism 50.

[0039] It should be noted that the interval distance between the two transverse sliding seats 341 should be equal to the interval distance between the printing mechanism 20 and the first drying mechanism 50, so that when one transverse sliding seat 341 enters the first drying mechanism 50, the other transverse sliding seat 341 is located in the working area of the printing mechanism 20 to realize cyclic and coherent work; the second transverse supporting fixture 44 has the same structure and principle as the first transverse supporting fixture 34, so it will not be elaborated here.

[0040] Further, in this embodiment, the first drying mechanism 50 includes: a drying oven 501; a UV lamp (not shown in the figure) is provided inside the drying oven 501, a heat dissipation fan 502 is provided at the top of the drying oven 501, a slideway 503 is provided at the bottom of the inner wall of the drying oven 501, a cover plate 504 is provided inside the slideway 503, one side of the cover plate 504 is connected with a pushing air cylinder 505, the pushing air cylinder 505 is located outside the drying oven 501, and the cover plate 504 slides away from or towards the direction where the first feeding mechanism 30 is located under the drive of the pushing air cylinder 505; a lifting gate 506 is provided on the side of the drying oven 501 facing the second feeding mechanism 40. Specifically, a UV lamp is provided inside the drying oven 501. The characters printed on the product are dried by the high heat generated when the UV lamp works. Since the UV lamp generates relatively high heat during operation after drying, and the heat will continue to increase with the working time of the UV lamp, to avoid damage to the electrical appliances inside the first drying mechanism 50 due to being in a high-temperature state for a long time, a heat dissipation fan 502 is provided at the top of the drying oven 501. When the temperature inside the drying oven 501 exceeds a predetermined value, the heat dissipation fan 502 works to extract the temperature inside the drying oven 501, thereby controlling the temperature inside the drying oven 501; a slideway 503 is further provided at the bottom of the inner wall of the drying oven 501, a cover plate 504 is provided inside the slideway 503, a pushing air cylinder 505 is provided on one side of the cover plate 504, and the cover plate 504 can slide inside the slideway 503 through the pushing air cylinder 505 to realize the closing or opening of the bottom of the drying oven 501. When drying is not required, the cover plate 504 can retract into the drying oven 501 for light shielding; a lifting gate 506 is further provided on the side of the drying oven 501 facing the first horizontal guide rail 33. When the product needs to be sent into the drying oven 501, the lifting gate 506 rises, the product enters, and then the first horizontal supporting fixture 34 exits, and the lifting gate 506 descends to close the drying oven 501.

[0041] In summary, by providing a printing mechanism 20 in the middle of the workbench 10 and a first feeding mechanism 30 and a second feeding mechanism 40 arranged around the printing mechanism 20, the present invention reduces the equipment length. At the same time, the head and tail connection of the first feeding mechanism 30 and the second feeding mechanism 40 realizes the transportation of the product, which is both the starting point and the ending point. The staff only needs to stand at the starting point to place the product, thereby reducing the labor intensity of the staff, reducing the labor arrangement, and reducing the labor cost.

[0042] The present invention is not limited only to what is described in the specification and embodiments. Therefore, for those skilled in the art, additional advantages and modifications can be easily achieved. Thus, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrated examples shown and described herein.
