The accuracy is uncontrollable, and the error during the inkjet process cannot be controlled, which cannot meet the requirements of automation.

[0003] At the same time, compared with the pad printing of traditional non-PCB materials, the pad printing platform for PCB has higher requirements for accuracy.

[0004] Based on the problems of poor accuracy and low automation of the existing inkjet printer feeding platform, it is urgent to develop a PCB board pad printing platform with high accuracy and high automation. Summary of the Invention

[0008] As a preferred embodiment, the bottom plate is preferably a marble bottom plate; the marble plate has good stability, high hardness and strength, and can still maintain high accuracy under heavy load.

[0009] As a preferred embodiment, the fixture bottom plate is provided with positioning pins, and the positioning pins have the function of mechanical positioning of the pins to ensure that the installation horizontal height is consistent.

[0010] As a preferred embodiment, it further includes a lifting cylinder, which is connected to the lifting plate to drive the lifting of the lifting plate. When the lifting plate rises to receive the PCB board and the lifting plate descends and is engaged with the matching holes of the lifting plate, the PCB board is placed on the upper plate of the fixture; further preferably, the lifting cylinder is arranged in the moving platform cavity.

[0011] As a preferred embodiment, the induction photoelectric is used to detect whether there is a PCB board material above, and the pad printing and inkjet coding of the PCB board are realized by the linear movement of the linear motor.

[0025] It should be noted that if there are directional indications (such as up, down, left, right, front, back, top, bottom,...) involved in the embodiments of the present utility model, then the directional indications are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0026] In this application, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. It can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0027] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0028] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, such descriptions of "first", "second", etc. are only for descriptive purposes and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] Currently, due to the uncontrollable accuracy caused by manual feeding of the material receiving platform of the existing inkjet printers, there is a problem that the automation requirements cannot be met. To solve the above technical problems, the present invention proposes a PCB board pad printing platform.
