Description

Supporting device

Technical Field

The invention relates to a supporting device for processing lens shading sheets, in particular to a supporting device for shading and cleaning a mobile phone lens shading sheet or a spacer.

Background

Digital cameras and cellular phones with digital cameras have rapidly become widespread, and cameras used therein are also continuously improving. In the field of photography or imaging technology, one of important technologies is to remove unnecessary incident light or stray light to prevent ghosting from occurring in a captured image and to prevent distortion of a captured picture. Under strong light irradiation, the light entering the lens is difficult to be completely absorbed, and part of the light is reflected. The reflected light is further reflected or refracted and then is incident on the image sensor to generate glare, which causes imaging blurring, such as generation of ghost and other defects.

Flare is a phenomenon in which a part of a screen is white light, and is likely to occur particularly when incident light is strongly incident, such as when a camera is directed to a light source. The ghost refers to a phenomenon in which an object appears at a different position from a position where the object actually appears due to multiple reflection of incident light or the like.

To avoid or eliminate these drawbacks, a light-shielding sheet is generally provided between lenses in the imaging lens. The lens shading sheet plays a role in eliminating stray light and blocking stray light. However, if the lens shade or the lens spacer is not subjected to the extinction process due to the processing process, the lens may generate a flare phenomenon after being assembled into the lens, thereby affecting the photographing effect.

In general, the light-shielding sheets are subjected to a matting treatment by stringing the light-shielding sheets on a copper wire and then putting the strung light-shielding sheets into a matting apparatus for etching treatment. Usually, many strings of anti-dazzling screens are put into a delustering device for processing at the same time, so that copper wires strung with anti-dazzling screens are easy to intertwine and knot. In order to avoid the situation, a small number of the anti-dazzling screens which are connected in series can be processed at one time, the copper wires are cut off after extinction is completed, and the anti-dazzling screens are placed in a cleaning cage for cleaning. The labor intensity of corrosion and cleaning is high, and the efficiency is low.

Detailed Description

Fig. 1 is a perspective view of a support device according to the present invention. As shown in the figure, the supporting device mainly comprises two stand bodies 1 arranged parallel to each other. In the present embodiment, the holder main body 1 is a rectangular plate-like object. Of course, the stand body 1 may be a square plate, an isosceles trapezoid plate, or the like. A connecting rod 2 is arranged between the bracket main bodies 1. The links 2 are provided at four corners of the stand main body 1. In the present embodiment, the link 2 and the holder main body 1 are connected to each other by a bolt to form a detachable connection. Of course, other shapes or cross-sections of rigid material may be used for the connecting rod 2. For example, it may be a bar of rectangular cross-section or a plate. As long as rigid connection between the holder main bodies 1 is ensured while allowing liquid for matting or cleaning the light-shielding plate to smoothly flow between the holder main body 1 and the link 2.

According to one embodiment of the present invention, the bracket body 1 is a square plate, and four corners of the bracket body 1 are connected with the connecting rods 2 through connecting pieces to form a supporting frame. In the present embodiment, the fixing posts 6 are provided at the upper ends of the bracket body 1 connected to both ends of the connecting rod 2. The fixing columns 6 are arranged at the upper end of the bracket main body 1 at equal intervals, and the arrangement mode of the fixing columns 6 at the upper ends of the bracket main body 1 at the two ends of the connecting rod 2 is the same.

As shown in fig. 1, in the present embodiment, a support block 3 is further provided. The supporting blocks 3 are arranged on the mutually opposite surfaces of the bracket main body 1 and are used for providing a fixed pivot for hanging the supporting device of the shade to be processed. As shown in fig. 1, a support block 3 is fixed to the holder body 1 by a bolt on the other side of the holder body 1. This fastening allows a detachable connection between the bearing block 3 and the holder body 1, which facilitates the removal and replacement of parts that may be damaged. In the embodiment shown in fig. 1, the bearing blocks 3 are arranged on the carrier body 1 in two opposite positions.

A vertical supporting rod 4 is provided between two supporting blocks 3 mounted on the opposing bracket bodies 1. The longitudinal support bar 4 is connected to the support block 3, for example, in the embodiment shown in fig. 1, the longitudinal support bar 4 is fixed to the support block 3 by a pin or pin with a transition fit. The longitudinal support bar 4 and the support block 3 can also be detachably connected to each other, for example by means of screws. The function of the supporting longitudinal bars 4 is on the one hand to provide supporting points or supporting positions for supporting the supporting parts for supporting the workpieces to be processed or the gobos; on the other hand, the rigidity of the frame-type structure formed by the bracket main body 1 and the connecting rod 2 is enhanced, so that the frame-type structure is more stable and firm. In the embodiment shown in fig. 1, the vertical support bar 4 and the connecting rod 2 are arranged parallel to each other.

As shown in fig. 1, a support crossbar 5 is provided between the two support side rails 4. The two ends of the supporting transverse rod 5 are respectively detachably connected with the ends of the corresponding supporting longitudinal rods 4. The supporting longitudinal bars 4 and the supporting transverse bars 5 are connected to each other by bolts, for example. In the embodiment shown in fig. 1, the support rail 5 is provided in correspondence with a groove 101 on the side wall of the stand body 1. Since the side walls of the groove 101 are stepped and have a width decreasing from top to bottom (the top-bottom direction in fig. 1), the length of the corresponding support rail 5 decreases accordingly. The function of the support rails 5 is primarily to provide a support structure for the work piece or gobo to be processed.

As shown in fig. 1, the support bar 5 is provided with fixing posts 6. The fastening posts 6 are fastened vertically at a distance from one another to the supporting cross-bar 5. The distance between the fixed posts 6 is standard for subsequent operations, for example, the distance between the center lines of two fixed posts 6 is 15 cm. This distance facilitates the operator to wind and fix a wire, such as a copper wire or the like, for hanging the shade sheet on the fixing post 6. Since the length of the supporting cross rod 5 arranged from top to bottom is gradually reduced, the number of the fixing columns 6 arranged on the supporting cross rod 5 is gradually reduced. In one embodiment according to the invention, the shade to be processed is threaded through with a thread, and a total of seventy strings of shades can be suspended. Different numbers of strings of gobos can be suspended based on different numbers of support bars 5, different lengths etc.

In the present embodiment, the fixing posts 6 are fixed to the support rail 5 by interference fit. Of course, other fixing means, such as a detachable connection by a thread, or a connection by welding, etc., may be adopted.

Fig. 2 shows in a front view a particular embodiment of the stand body 1 in the support device according to the invention. As shown in the drawing, in the present embodiment, the outer contour of the holder main body 1 is rectangular. A groove 101 is provided along one long side of the rectangle towards the other long side. Two opposite side walls of the groove 101 on the holder body 1 shown in fig. 2 converge or converge in a stepwise manner toward the center line of symmetry of the holder body 1, thereby forming three steps on the side walls. Of course, different steps may be provided according to the size of the light-shielding member to be processed and the size of the holder main body 1. The number of steps may also be different, depending on the purpose of the invention. For example, only one step, or two steps, etc. may be provided. As shown in fig. 2, one long side of the groove 101 that faces the rectangle is open, i.e., the upper side in the drawing is an open side.

As shown in fig. 2, a through hole 106 is further provided in the holder body 1 for mounting the link 2. A connection hole 107 is also provided at a step edge of the side of the recess 101 for mounting a supporting device for suspending the light-shielding sheet to be processed. These through holes 106 or connecting holes 107 are respectively arranged symmetrically with respect to the center line of the holder main body 1. In other embodiments according to the present invention, these through holes 106 and connection holes 107 may not be provided.
