All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model.

In the description of the present utility model, it should be understood that, in the description of the present utility model, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more features.

In the embodiment of the present utility model, the circuit board processing apparatus mainly includes a beam 10, a spindle module 120, and a plurality of dust covers 130. The beam 10 is provided with a guide rail 100 and a stator 110, wherein the guide rail 100 extends along the X direction and is used for bearing the spindle module 120 and guiding the movement of the spindle module 120 in the X direction; the stator 110 is a stator structure of a linear motor, and has an extending direction consistent with the guide rail 100, and is also extended along the X direction, and the stator 110 and the mover cooperate to form a linear motor for driving the spindle module 120 to move. The spindle module 120 is disposed on the guide rail 100, and is carried by the guide rail 100 and guided by the guide rail 100; the stator 110 is located between the spindle module 120 and the cross beam 10, and the spindle module 120 is provided with a mover capable of being engaged with the stator 110, so that the stator 110 can be engaged with the mover to drive the spindle module 120 to move along the guide rail 100. The dust cover 130 is disposed on two sides of the spindle module 120 in the extending direction X of the guide rail 100, and is connected to the spindle module 120, and the dust cover 130 shields the stator 110 on one side of the stator 110 away from the beam 10.

In some embodiments, the dust cap 130 shields the grating ruler 140 on a side of the grating ruler 140 remote from the beam 10. Thus, the dust cover 130 can protect the grating ruler 140 at the same time, and ensure the normal operation of the equipment.

In some embodiments, the circuit board processing apparatus may only provide one spindle module 120, and correspondingly, two dust covers 130 may be connected to two sides of the spindle module 120, and the other ends of the two dust covers 130 are respectively connected to two sides of the beam 10, so that the two dust covers 130 and the spindle module 120 form a region where the width in the extending direction of the guide rail 100, i.e., the X direction, remains unchanged, to shield the stator 110, and maintain the shielding effect. In addition, the dust cover 130 may be configured to be extendable and retractable in the extending direction of the guide rail 100, so that when the spindle module 120 moves along the guide rail 100, the dust cover 130 may be adaptively extended or shortened according to the position change of the spindle module 120, that is, when one side of the dust cover 130 is extended, the other side of the dust cover 130 is correspondingly shortened, so that the shielding effect of the dust cover 130 is not affected, and the movement of the spindle module 120 is not interfered.

In some embodiments, the spindle modules 120 are a plurality, and the plurality of spindle modules 120 are disposed on the rail 100 at intervals.
