Description

Technical Field

[0001] The utility model relates to the technical field of dental imaging, in particular to an anti-card device for a CR scanner. Background Art

[0002] CR equipment is an X-ray imaging device. Its working principle is to record the X-ray image on a special image recording plate, and then convert the image on the image plate into a digital signal through a reading device, which is then processed and displayed by a computer. It is often used in medical testing.

[0003] In existing CR equipment, when scanning objects using the scanning device, it is often impossible to ensure that the height of the object matches the height of the hatch entrance. Inserting an object for scanning during this period can force the machine to operate, causing malfunction or even damage. Furthermore, some operators, for convenience, ignore safety regulations and directly remove objects from the pallet. This can cause jamming and pose safety risks.

[0004] Furthermore, the biggest cause of jamming in CR equipment currently is that doctors are unfamiliar with the use of IP panels. Before scanning, a protective sheet is placed over the IP panel to protect it from scratches and to block light, enhancing image quality. However, many doctors place the protective sheet and the IP panel in the scanning tray, causing the sheet and IP panel to become stuck inside the scanner. This necessitates a return to the manufacturer for repair, significantly increasing after-sales costs and reducing customer satisfaction. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The utility model provides Figure 1-7 The anti-card device for a CR scanner shown is used to avoid card problems in the scanner 1. Symmetrical proximity sensors 10 are provided on both sides of the door of the scanner 1. An MCU 3 and a buzzer 9 are fixed on the front side of the scanner 1.

[0032] The scanner 1 is provided with a tray 6 , an IP board 7 is placed on the top of the tray 6 , the proximity sensor 10 is provided at the input end of the MCU 3 , and the buzzer 9 is provided at the output end of the MCU 3 .

[0033] The scanner 1 is provided with a driving component for driving the tray 6 to move. The driving component is provided at the output end of the MCU 3 and can be a motor screw drive structure.

[0034] When in use, place the IP plate 7 on the tray 6. At this time, the two proximity sensors 10 can detect the height of the object on the tray 6. When the detection is abnormal, it means that the following abnormal conditions have occurred, such as the IP plate 7 is not flat, the protection plate is put in, or the object on the tray 6 is taken by hand, etc. At this time, the MCU3 will control the driving component on the scanner 1 for driving the tray 6 to stop scanning. At the same time, the buzzer 9 will sound an alarm to avoid the occurrence of card phenomenon.

[0035] During the scanning process, blocking the door of the scanner 1 can prevent the user from taking objects on the tray 6 by hand. Figure 1 、 5 As shown in Figures 7 and 8, a baffle 4 for shielding the tray 6 is provided above the scanner 1, and retractable components 2 are provided on both sides of the scanner 1. The baffle 4 shields the top of the door of the scanner 1 during the scanning process to avoid direct touch of objects with hands.

[0036] The retractable assembly 2 includes a linear motor 201 fixedly mounted on a corresponding side of the scanner 1. A sleeve 202 is mounted on the mover of the linear motor 201 via a rotating shaft. The linear motor 201 is mounted at the output end of the MCU 3.

[0037] The retractable assembly 2 further includes a driving arm 203 , the sleeve 202 is sleeved on the outer end of the driving arm 203 , one end of the driving arm 203 is movably connected to the scanner 1 via a rotating shaft, and the other end of the driving arm 203 is fixedly connected to the baffle 4 .

[0038] When the object and the IP plate 7 are placed on the tray 6 normally, the baffle 4 is located above the scanner 1 and will not block the tray 6. After the objects are placed, the mover of the linear motor 201 moves and drives the sleeve 202. The sleeve 202 slides along the driving arm 203 while driving the driving arm 203 to rotate, thereby driving the baffle 4 to rotate and rotate the baffle 4 to the front side of the cabin door of the scanner 1, thereby blocking the cabin door and effectively preventing the hand from approaching the cabin door.

[0039] If the object placed on the tray 6 is too heavy, the tray 6 needs to be supported after it is extended, such as Figure 1 、 4As shown in , 7 , a support assembly 8 is provided on the front side of the scanner 1, and the support assembly 8 includes a base 801. A support frame 803 is provided on the top of the base 801.

Two electric push rods 802 are provided between the support frame 803 and the base 801 . The electric push rods 802 are provided at the output end of the MCU 3 .

[0041] When the tray 6 extends forward, the electric push rod 802 extends upward, pushing the support frame 803 to move upward and lift it to the bottom end of the tray 6. The ball 804 contacts the bottom end of the tray 6, and the tray 6 extending outside the cabin door is supported by the support assembly 8, thereby improving the stability of the tray 6.

[0042] Before placing the object, first clean the tray 6, such as Figure 1 、 6 As shown in , 7 , a dust removal assembly 5 is provided on the front side of the scanner 1. The dust removal assembly 5 is located above the door of the scanner 1. The dust removal assembly 5 includes an air flow channel 501 fixedly provided on the front side of the scanner 1;

[0043] Two fans 502 are fixedly provided at the top of the air flow channel 501 . The fans 502 are provided at the output end of the MCU 3 . An exhaust slot 503 is provided at the bottom of the air flow channel 501 .

[0044] Before placing objects such as the IP board 7 on the tray 6, turn on the fan 502 and drive the external air flow through the fan 502, so that the air flows into the air flow channel 501. The air entering the air flow channel 501 is finally blown out obliquely downward through the exhaust slot 503 and blown toward the tray 6, thereby blowing away dust and impurities on the tray 6 to prevent the dust and impurities from causing the IP board 7 to tilt after being placed.

[0045] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
