Description

Technical Field

[0001] The utility model relates to the technical field of chip mounters, in particular to a reflector filter device. Background Art

[0002] As the name implies, the nozzle of the placement machine is a workpiece used on the placement machine to absorb and place SMT components. There are various types and materials of nozzles for placement machines on the market. In the existing surface mounting process, the placement process is that the placement machine uses the nozzle at the end of its placement head to suck various components from the component tray belt or tray and bring them to the correct position of the printed circuit board to be mounted.

[0003] In the image recognition of existing placement machines, the light source is reflected by the reflector to the material or the nozzle, and then projected to the recognition camera to identify the shape, size and position of the material or the nozzle. In order to avoid the influence of various external lights on the camera recognition, a filter is usually installed in front of the lens to filter or absorb invalid light, thereby improving the clarity and recognition accuracy, and reducing the defective rate of placement.

[0004] During actual use, attention should be paid to the cleaning of the filter. When the filter is contaminated by dust, fingerprints, etc., the image quality will be reduced. In the prior art, when the surface of the filter is contaminated by dust, fingerprints, etc., the filter needs to be removed for cleaning, and then the cleaned filter is installed in front of the lens. The operation is relatively complicated, and during the disassembly and installation process, there is still a possibility of touching the filter with hands, thereby contaminating the cleaned filter again and affecting the image quality of the filter. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a reflector filter device, which does not need to be removed from the mounting ring when cleaning, and avoids contact between the hands and the filter during cleaning and installation, thereby avoiding affecting the imaging quality of the filter.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A reflector filter device comprises a mounting ring, a filter mounted inside the mounting ring, and a cleaning assembly arranged on one side of the mounting ring and acting on the surface of the filter; the cleaning assembly comprises a first guide and a second guide respectively arranged on both sides of the upper surface of the mounting ring and sliding along the circumferential direction of the mounting ring surface, and a cleaning subassembly for connecting the first guide and the second guide; the second guide is detachably arranged on the mounting ring; the cleaning subassembly comprises a first cleaning plate and a second cleaning plate hinged to each other; the outer end of the first cleaning plate is rotatably connected to the first guide, and the outer end of the second cleaning plate is slidably connected to the second guide.

[0008] More preferably, a handle arranged along the height direction is movably sleeved inside one end of the hinged connection between the first cleaning plate and the second cleaning plate, and an avoidance groove adapted to the handle is penetrated through the second cleaning plate.

[0009] More preferably, a receiving groove matched with the first guide member is formed on the top of the second guide member, and when the second cleaning plate is turned over to overlap with the first cleaning plate, the second guide member is buckled with the first guide member.

[0010] More preferably, the first guide member includes a sliding portion which is arranged in the mounting ring and slides circumferentially along the mounting ring, and a guide portion which is vertically fixed to the top of the sliding portion; the diameter of the guide portion is smaller than the diameter of the sliding portion, and the diameter of the guide portion is equal to the inner diameter of the accommodating groove; a first sliding groove which is adapted to the second guide member is opened around the top of the mounting ring, and a third sliding groove which is adapted to the sliding portion is opened around the inside of the mounting ring, and the first sliding groove is connected to the second sliding groove through the third sliding groove which is adapted to the guide portion.

[0011] The utility model has the following beneficial effects:

[0025] When in use, the first cleaning plate 331 and the second cleaning plate 332 are rotated so that the first cleaning plate 331 and the second cleaning plate 332 clean the surface of the filter 2. When use is over, the second guide member 32 is moved upward so that the bottom of the second guide member 32 is separated from the mounting ring 1, and then the second cleaning plate 332 is folded to the top of the first cleaning plate 331. At this time, the second guide member 32 is also folded to the top of the first guide member 31, and finally the cleaning assembly 3 is rotated so that the cleaning assembly 3 is turned away from the surface of the filter 2, thereby avoiding blocking the filter 2. In the device, through the cooperation of the first cleaning plate 331, the second cleaning plate 332, the first guide member 31 and the second guide member 32, on the one hand, when the side of the filter 2 away from the lens is contaminated by dust, fingerprints, etc., it is convenient and quick to clean the filter 2 without disassembling the filter 2, which can improve the cleaning efficiency of the filter 2. On the other hand, since the filter 2 can be cleaned without disassembling the filter 2, it can be avoided that the hand touches the filter 2 when installing the cleaned filter 2, thereby avoiding the hand contamination of the cleaned filter 2, thereby improving the imaging quality of the filter 2.

[0026] As a possible implementation of the present scheme, preferably, a handle 333 arranged in the height direction is provided inside a movable sleeve at one end of the hinged connection between the first cleaning plate 331 and the second cleaning plate 332, and an avoidance groove 334 adapted to the handle 333 is penetrated through the second cleaning plate 332; the setting of the handle 333 can facilitate the rotation of the cleaning component 3, thereby avoiding the contact between the hand and the filter 2 when the cleaning component 3 is rotated.

[0027] As a possible implementation manner of the present scheme, preferably, a accommodating groove 321 adapted to the first guide member 31 is provided at the top of the second guide member 32, and when the second cleaning plate 332 is flipped to overlap with the first cleaning plate 331, the second guide member 32 is engaged with the first guide member 31; by folding the second guide member 32 and engaging it with the first guide member 31, the folded second cleaning plate 332 can be further limited, thereby enhancing the stability of the cleaning assembly 3 when it is fixed.

The second slide groove 12 is connected through the third slide groove 13 adapted to the guide portion 312; through the cooperation of the sliding portion 311 and the third slide groove 13, the first guide member 31 can be limited to prevent the first guide member 31 from detaching from the mounting ring 1; through the cooperation of the guide portion 312 and the second slide groove 12, the sliding of the first guide member 31 can be limited; through the cooperation of the second guide member 32 and the first slide groove 11, when the handle 333 is turned, the cleaning component 3 can rotate along the center of the filter 2 to ensure that the cleaning component 3 can achieve all-round cleaning of the filter 2.

[0029] The working principle of this device is:

[0030] In the present device, the filter 2 is a plane mirror, which has a wider range of uses and can save space. When the surface of the filter 2 needs to be cleaned, the cleaning assembly 3 is rotated until the end away from the first guide member 31 is located at the center of the filter 2, and the handle 333 is moved upward so that the bottom of the handle 333 is flush with the bottom of the first cleaning plate 331, and the second guide member 32 is moved upward until the bottom is flush with the upper surface of the first cleaning plate 331, and then the second cleaning plate 332 and the second guide member 32 are turned over until the second cleaning plate 332 is against the surface of the filter 2. At this time, the second guide member 32 is located above the first slide groove 11, and the second guide member 32 is pressed downward so that the second guide 3 2 is in contact with the bottom of the first slide groove 11, and the handle 333 is turned to make the cleaning assembly 3 rotate around the center of the filter 2, so that the first cleaning plate 331 and the second cleaning plate 332 clean the surface of the filter 2 while rotating; when the cleaning is completed, the second guide member 32 is moved upward to the bottom to disengage from the first slide groove 11, and the second cleaning plate 332 and the second guide member 32 are folded to above the first cleaning plate 331 and the first guide member 31, and the second guide member 32 is pressed downward to make the second guide member 32 engage with the first guide member 31, and then the cleaning assembly 3 is rotated so that the handle 333 is located above the first slide groove 11, and the handle 333 is pressed downward.
