[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] As disclosed in the background technology, in the prior art, a marking positioning jig is usually required to fix the device to be processed in order to complete the laser marking action. After the laser marking is completed, the device is removed, and dust or metal foreign matter is easily left in the positioning jig, which affects the subsequently placed devices and easily causes the residual dust metal or foreign matter to contaminate the internal transistors of the subsequent devices, causing device performance failure.

[0032] Furthermore, the current processing method is usually to manually use an external air nozzle to spray air to clean the positioning fixture after each cleaning. This requires additional cleaning operations, is very inconvenient, and leads to a complex overall structure.

[0033] In order to solve the above problems, the utility model provides a novel self-cleaning printing jig, which can achieve cleaning without additional manual operation, and is very convenient. The specific structure of the self-cleaning printing jig is described in detail below.

[0036] The self-cleaning printing fixture 100 provided in this embodiment includes a shell 110, a rotating supporting platform 130 and a cleaning base 150. The cleaning base 150 is provided with a cleaning water inlet hole 151, and the cleaning water inlet hole 151 is used to connect with an external water pipe. The shell 110 is installed on the cleaning base 150 and is arranged around the cleaning water inlet hole 151. The rotating supporting platform 130 is rotatably installed on the top of the shell 110 and is provided with a supporting groove 131 for accommodating the device to be printed, and the rotating supporting platform 130 corresponds to the cleaning water inlet hole 151. The cleaning water inlet hole 151 is used to spray cleaning water upward and clean the supporting groove 131 on the rotating supporting platform 130.

[0037] It should be noted that the cleaning base 150 in this embodiment is installed on an external machine, and a booster pump can be provided on the external water pipe, so as to facilitate the cleaning water injection through the water inlet 151. In actual use, firstly, the bearing groove 131 of the rotating bearing platform 130 is facing upward, and the device to be printed is placed to complete the conventional laser printing action. After removing the device, the rotating bearing platform 130 can be rotated downward so that the bearing groove 131 faces downward.

[0038] In this embodiment, a driving member 170 is further provided on the cleaning base 150, and the driving member 170 is transmission-connected with the rotating bearing platform 130, and is used to drive the rotating bearing platform 130 to rotate relative to the housing 110. Specifically, the driving member 170 can be a stepping motor, and the rotating bearing platform 130 is driven by the stepping motor to rotate, so that the bearing groove 131 rotates between the upper side and the lower side, which is convenient for turning to the lower side for cleaning after the laser printing is completed.

[0039] In this embodiment, both side surfaces of the rotating carrying platform 130 are provided with carrying grooves 131. Specifically, both upper and lower side surfaces of the rotating carrying platform 130 are provided with carrying grooves 131, and the shape of the carrying grooves 131 is adapted to the shape of the device to be printed, so as to accommodate and position the device to be printed. In addition, by providing the carrying grooves 131 on both the upper and lower sides, the upper side can still perform laser printing while the lower side is being cleaned, thereby improving printing efficiency.

[0040] In this embodiment, a drainage groove 153 is further provided on the cleaning base, and the bottom of the housing 110 is correspondingly mounted around the drainage groove 153, and the drainage groove 153 is used to discharge the cleaned sewage to the outside. Specifically, the housing 110 can be correspondingly mounted at the edge of the drainage groove 153, and the width of the drainage groove 153 is greater than the thickness of the housing 110, so that the drainage groove 153 will not be filled up by the housing 110 and its drainage effect is guaranteed.

[0041] In this embodiment, a drainage hole 155 penetrating the cleaning base is formed on the bottom wall of the drainage groove 153, and the diameter of the drainage hole 155 is larger than the diameter of the cleaning water inlet hole 151. Specifically, the diameter of the drainage hole 155 is larger, and there are multiple drainage holes 155, so that the drainage effect is better and the clean water in the drainage groove 153 is prevented from accumulating.

Specifically, the spray platform 190 is plate-shaped as a whole and is fixedly mounted on the cleaning boss 157, and there are multiple spray holes 191, which are disposed one by one corresponding to the multiple cleaning water inlet holes. The spray hole 191 can be an expanded hole structure, and a grid is added, so that the water column sprayed from the cleaning water inlet hole is dispersed into multiple streams of water, thereby achieving a spray effect.

[0045] In this embodiment, a spray boss 193 is convexly disposed on the top surface of the spray platform 190, and the spray hole 191 is opened on the spray boss 193. Specifically, the arrangement of the spray boss 193 can raise the spray hole 191, and can further avoid contamination of the spray hole 191 in the drain groove 153.

[0046] In this embodiment, rotating shafts 133 are provided at both ends of the rotating bearing platform 130, and shaft holes 111 are provided on the opposite side walls of the housing 110.
