Technical Field

[0001] This utility model relates to the field of screen printing technology, and in particular to a screen printing machine for outer casing. Background Technology

[0002] Currently, besides screen printing on films and similar products, some businesses also use screen printing on product casings (such as TV casings, computer cases, etc.). However, screen printing on casings usually requires positioning the product before printing can begin. This method typically allows only one casing to be transferred to the screen printing unit at a time for printing; after printing, the product needs to be transferred back to its original position for unloading and replacement, resulting in low efficiency. Summary of the Invention

[0003] This invention addresses the problems of existing technologies by providing a screen printing machine for outer shells, which enables continuous screen printing on outer shells, thereby improving efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a shell screen printing machine, including a machine body, a transmission mechanism and a screen printing mechanism both disposed on the machine body. The transmission mechanism includes a transmission module, a lifting module and a positioning module. The lifting module is disposed on the transmission module and located directly below the screen printing mechanism. The transmission module is used to transmit the shell movement, the lifting module is used to lift the shell, the positioning module is used to position the side of the shell lifted by the lifting module, and the screen printing mechanism is used to perform screen printing on the shell after it has been lifted and positioned.

[0005] Furthermore, the lifting module includes a lifting platform, lifting support components, and a lifting cylinder. The transmission module is a transmission roller module. The lifting cylinder is installed on the machine body and located directly below the transmission module. The lifting platform is located between the lifting cylinder and the transmission module. The lifting platform is installed on the piston rod of the lifting cylinder. There are multiple lifting support components. The lifting support components are installed on the lifting platform and are used to lift the outer shell after passing through the transmission module. The positioning module is set on the lifting platform and located around the lifting support components.

[0006] Furthermore, the lifting module also includes a positioning switch, which is located on the lifting platform and is used to identify whether the outer casing is in position.

[0007] Furthermore, the number of positioning modules is two, and each positioning module includes a positioning cylinder and a positioning component. The positioning cylinder is installed on the lifting platform, and the positioning component is installed on the piston rod of the positioning cylinder. The two positioning components are arranged facing each other, and the transmission module is located between the two positioning components.

[0008] Furthermore, the positioning element includes a main body and two extensions, which are respectively disposed at both ends of the main body and located on the same side of the main body. The main body is used to abut against the side of the outer shell, and the two extensions are used to abut against the front end and rear end of the main body, respectively.

[0009] Furthermore, the end of the extension away from the main body is provided with a guide slope, and the end of the guide slope away from the main body is connected to an arc surface.

[0010] Furthermore, the machine body is equipped with a gantry frame, the screen printing mechanism is located on the gantry frame, and the lifting module is located directly below the gantry frame.

[0011] The beneficial effects of this utility model are as follows: This utility model, through the cooperation of a transmission module, a lifting module, and a positioning module, enables the shell to be lifted to detach from the transmission module after it has been transported to its position, and then positioned for screen printing. This ensures that the position of the shell will not deviate, thus guaranteeing the screen printing effect. Furthermore, since the shell is automatically positioned during the transmission process, the screen printing operation can be completed in a continuous flow, resulting in high efficiency.

Detailed Implementation

[0016] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0017] like Figures 1 to 3As shown, the present invention provides a shell screen printing machine, including a machine body 1, a transmission mechanism 2 and a screen printing mechanism 3 both disposed on the machine body 1. The transmission mechanism 2 includes a transmission module 4, a lifting module 5 and a positioning module 6. The lifting module 5 is disposed on the transmission module 4 and located directly below the screen printing mechanism 3. The transmission module 4 is used to transmit the shell movement, the lifting module 5 is used to lift the shell, the positioning module 6 is used to position the side of the shell lifted by the lifting module 5, and the screen printing mechanism 3 is used to perform screen printing on the shell after it has been lifted and positioned.

[0018] During operation, the operator transfers the outer casing or the carrier containing the casing (hereinafter referred to as the casing) to the transfer module 4. The casing is then transferred by the transfer module 4 to the corresponding position below the screen printing mechanism 3. The lifting module 5 then lifts the casing to detach it from the transfer module 4. The positioning module 6 then positions the lifted casing laterally, precisely adjusting its posture and position to ensure the screen printing position of the screen printing mechanism 3 meets requirements. After screen printing is completed, the positioning module 6 and the lifting module 5 are sequentially reset, allowing the casing to fall back onto the transfer module 4 for unloading. This invention enables continuous screen printing of casing products, effectively improving efficiency.

[0019] The screen printing mechanism 3 of this utility model is a conventional structure, and will not be described in detail here.

[0020] In this embodiment, the lifting module 5 includes a lifting platform 51, lifting support members 52, and lifting cylinder 53. The transmission module 4 is a transmission roller module. The lifting cylinder 53 is installed on the machine body 1 and located directly below the transmission module 4. The lifting platform 51 is located between the lifting cylinder 53 and the transmission module 4. The lifting platform 51 is installed on the piston rod of the lifting cylinder 53. There are multiple lifting support members 52. The lifting support members 52 are installed on the lifting platform 51 and are used to lift the outer shell after passing through the transmission module 4. The positioning module 6 is set on the lifting platform 51 and located around the lifting support members 52.

[0021] When the outer casing is in place, the lifting cylinder 53 controls the lifting platform 51 to lift, so that the lifting support 52 extends from the gap between the adjacent transmission modules 4 and directly above the transmission module 4, achieving the effect of lifting the outer casing; after the outer casing is lifted to the preset height, the positioning module 6 is activated to adjust the posture and position of the outer casing from the side, so that the outer casing reaches the desired posture and position, ensuring the accuracy of the silkscreen position.

[0022] Specifically, the lifting module 5 also includes a positioning switch 54, which is disposed on the lifting platform 51. The positioning switch 54 is used to identify whether the outer casing is in position. The positioning switch 54 is preferably a commonly used device such as a photoelectric switch or an infrared sensor. Its main purpose is to control the transmission module 4 to stop transmission after sensing that the outer casing is in position, and then the lifting module 5 lifts the outer casing until it is detached from the transmission module 4.

[0023] Specifically, there are two positioning modules 6. Each positioning module 6 includes a positioning cylinder 61 and a positioning component 62. The positioning cylinder 61 is installed on the lifting platform 51, and the positioning component 62 is installed on the piston rod of the positioning cylinder 61. The two positioning components 62 are arranged facing each other, and the transmission module 4 is located between the two positioning components 62.

[0024] In actual use, the positioning member 62 includes a main body 63 and two extension members 64. The two extension members 64 are respectively disposed at both ends of the main body 63 and are located on the same side of the main body 63. The main body 63 is used to abut against the side of the outer shell, and the two extension members 64 are respectively used to abut against the front end and the rear end of the main body 63.

[0025] The extension 64 is integrally formed with the main body 63. The main body 63 stops the side of the outer shell, while the two extensions 64 abut against the front and rear ends of the outer shell respectively, thereby achieving the purpose of stopping and positioning the four sides of the outer shell, and thus achieving the purpose of adjusting the posture and position of the outer shell.

[0026] Specifically, the end of the extension member 64 away from the main body 63 is provided with a guide slope 65, and the end of the guide slope 65 away from the main body 63 is connected to an arc surface 66. The arc surface 66 reduces the pressure generated by the collision between the extension member 64 and the misaligned outer shell, thereby protecting the outer shell and the extension member 64; while the guide slope 65 guides the misaligned outer shell to gradually contact the inner side of the extension member 64 as the extension member 64 extends, thereby achieving the repositioning effect.

[0027] The specific dimensions of the extension 64 and the main body 63 of this utility model can be set according to the actual specifications of the shell. The specific setting method is something that can be experimentally determined by those skilled in the art, and will not be described here.

[0028] In this embodiment, the machine body 1 is provided with a gantry frame 11, the screen printing mechanism 3 is provided on the gantry frame 11, and the lifting module 5 is located directly below the gantry frame 11, so that the screen printing mechanism 3 is suspended in the air to facilitate screen printing.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
