Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

Referring to fig. 1 and fig. 2, two schematic structural diagrams illustrating that a light source device provided in an embodiment of the present invention is installed on a screen printing machine, where the light source device may be applied to the screen printing machine, the screen printing machine includes a printing table 1 and two columns 2 arranged side by side and at an interval, and the light source device specifically may include: at least one light source assembly 3; the light source component 3 comprises a light-emitting component 30, one end of the light-emitting component 30 is movably connected with the surface of one upright post 2 close to the printing table top 1, and the other end of the light-emitting component 30 is movably connected with the surface of the other upright post 2 close to the printing table top 1; the light emitting member 30 is movable in a first direction and a second direction and can be positioned at the target position, wherein the first direction is a height direction of the column 2, and the second direction is a direction from the column 2 to the printing table 1. Therefore, the position of the light-emitting member 30 can be adjusted, and the recognition degree of the CCD camera is increased, so that the CCD camera can be effectively matched with the laser mark on the 110-plus 230nm film layer, and the CCD camera can completely grab the laser mark on the film layer, thereby completing the manufacture of the finished battery; in addition, the light-emitting member of the embodiment is arranged on the side face of the printing platform, compared with the existing light source arranged right above the silicon wafer, the reflected light of the light-emitting member of the embodiment has small influence on the recognition degree of the CCD camera arranged right above the silicon wafer, and the imaging effect of the CCD camera for capturing the laser mark is improved.

Specifically, the light source device includes at least one light source assembly 3, fig. 1 shows one light source assembly 3, and fig. 2 shows two light source assemblies 3, and if the light source device includes two or more light source assemblies 3, the light source assemblies 3 are spaced apart from each other in the height direction of the pillar 2. The present embodiment will be described below by taking one light source assembly 3 as an example.

Specifically, the Light source unit 3 includes a Light Emitting element 30, and the Light Emitting element 30 is a device capable of Emitting Light, such as a Light bulb, an LED (Light Emitting Diode) lamp, or the like. With reference to the reference direction of the drawing, one end of the light emitting member 30 is movably connected to the surface (front surface) of one of the pillars 2 close to the printing table 1, and the other end of the light emitting member 30 is movably connected to the surface (front surface) of the other pillar 2 close to the printing table 1. In practice, the movable connection of one component part to another component part is understood to mean: one component may be relatively movable, e.g. relatively movable and relatively rotatable, with respect to the other component.

In the prior art, the light source is usually arranged right above the printing platform, a plurality of CCD cameras are arranged around the light source, namely, the CCD cameras are also arranged right above the printing platform, therefore, after the light source irradiates on a silicon wafer on the printing platform, reflected light of the light source can possibly cause the light on the silicon wafer to be too bright, the CCD cameras are exposed obviously when grabbing, the influence on the recognition degree of the CCD cameras is large, and the imaging effect of the CCD cameras grabbing laser marks is poor. Compared with the existing light source arranged right above the silicon wafer, the light-emitting piece of the embodiment has small influence on the recognition degree of the CCD camera arranged right above the silicon wafer due to the reflected light of the light-emitting piece, and the imaging effect of the CCD camera for grabbing the laser mark is improved.

Specifically, the light emitting member 30 may be movable in a first direction and a second direction, and the light emitting member 30 may be positioned at a target position when moved to the target position. The first direction is a height direction of the pillar 2, that is, the first direction is an up-down direction in the figure, and the second direction is a direction from the pillar 2 to the printing table 1, that is, the second direction is a front-back direction in the figure. The position of the light-emitting member 30 can be adjusted, and the recognition degree of the CCD camera is increased, so that the CCD camera can be effectively matched with the laser mark on the film layer with the thickness of 110 plus 230nm, and the CCD camera can completely grab the laser mark on the film layer to complete the manufacture of the finished battery.

Specifically, one end of the light emitting member 30 may not only move in the first direction and the second direction, but also deflect with respect to one pillar (specifically, a side of the pillar 2 close to the light emitting member 30), and the other end of the light emitting member 30 may not only move in the first direction and the second direction, but also deflect with respect to the other pillar (specifically, a side of the other pillar 2 close to the light emitting member 30). Therefore, the light emitting member 30 of the present embodiment can not only adjust the position of the light emitting member 30, but also adjust the angle of the light emitting member 30, so as to further improve the matching degree between the CCD camera and the laser mark on the 110-230nm film layer.

It should be noted that, the moving manner of one end (or the other end) of the light emitting element 30 may be implemented in a sliding fit manner, for example, the sliding block is matched with the sliding groove, the roller is matched with the sliding rail, and the fastening element is matched with the threaded hole. The implementation manner of the deflection of one end (or the other end) of the light emitting element 30 relative to the corresponding upright 2 may be a hinge connection, a clearance fit between a hole and a shaft, and the like.

In the prior art, four light sources are usually arranged in a screen printing machine, and the four light sources are arranged around a plurality of CCD cameras to assist the CCD cameras in grabbing laser marks on a film layer of a battery 6 on a printing table top 1, wherein the film layer of the battery is between 70 nm and 110 nm. That is, in this embodiment, the light source device is added on the basis of the original light source structure of the screen printing machine, if the film layer of the battery 6 is between 70 nm and 110nm, the original light source structure is turned on, and the newly added light source device is turned off, and if the film layer of the battery 6 is between 110nm and 230nm, the newly added light source device is turned on, and the original light source structure is turned off. Therefore, on the basis of not changing the original light source and the original position, the present embodiment can also be suitable for the new requirement that the film layer of the battery is between 110 and 230 nm.

In some embodiments, one end of the light emitting member 30 is flush with the other end, that is, the position of one end of the light emitting member 30 is the same as that of the other end in the first direction and the second direction, so that the deflection angle of the two ends of the light emitting member 30 with respect to the corresponding pillars 2 is the same, that is, the light emitting member 30 as a whole can move in the up-down and front-back directions and can deflect. In other embodiments, one end and the other end of the light emitting member 30 may be uneven, and in this case, the positions of the two ends of the light emitting member 30 in the first direction and the second direction may be different, and the deflection angles of the two ends of the light emitting member 30 with respect to the corresponding pillars 2 may also be different.

It should be noted that the length of the light emitting member 30 is smaller than a first distance, and the first distance is a distance between a side surface (referred to as a first side surface) of one of the pillars 2 close to the light emitting member 30 and a side surface (referred to as a second side surface) of the other pillar 2 close to the light emitting member 30.

Specifically, as shown in fig. 1, one end of one cantilever 31 is fixedly connected to one end of the light emitting element 30, the other end of the one cantilever 31 is movably connected to the first side surface of one of the pillars 2, one end of the other cantilever 31 is fixedly connected to the other end of the light emitting element 30, and the other end of the other cantilever 31 is movably connected to the second side surface of the other pillar 2, so that the other end of the one cantilever 31 can drive one end of the light emitting element 30 to move in the up-down direction and the front-back direction and deflect relative to the one pillar 2, and the other end of the other cantilever 31 drives the other end of the light emitting element 30 to move in the up-down direction and the front-back direction and deflect relative to the other pillar 2. It can be seen that the illuminating element 30 and the two cantilevers 31 form a pattern similar to a "U" shape, the opening of which faces the printing table 1.

Specifically, in order to enable the cantilever 31 to drive the light emitting member 30 to move or deflect, the cantilever 31 and the corresponding side surface of the upright 2 close to the light emitting member 30 are not only parallel, but also have a gap.

In the embodiment of the present invention, as shown in fig. 1 and 2, the light source device further includes: two mounting plates 4, one mounting plate 4 corresponding to one upright post 2; each mounting plate 4 is used for being fixedly connected with the surface of the corresponding upright post 2 close to the printing table top 1; the other end of one cantilever 31 is movably connected with one mounting plate 4, and the other end of the other cantilever 31 is movably connected with the other mounting plate 4.
