Figure 5 The diagram shows the usage state of the dental X-ray film adsorbed in the adsorption-type loading and unloading device provided by this utility model. (See diagram for example.) Figure 1 , Figure 2 As shown and Figure 5 As shown, the suction-type dental X-ray film loading and unloading device provided in this embodiment includes: a loading and unloading device body 10, a pressing part 20, a hook part 30, a hook movable groove 40, a piston moving part 50, a guide rail part 60, a negative pressure chamber 70, and a suction nozzle part 80; wherein, the pressing part 20 is fixedly disposed on the outer wall of the first end of the loading and unloading device body 10; the guide rail part 60 is fixed in the internal cavity 11 of the loading and unloading device body 10, and the first end of the guide rail part 60 is fixed to the first end of the loading and unloading device body 10; the hook movable groove 40 is disposed on the loading and unloading device body 10; the hook part 30 is sleeved on the guide rail part 60, and the... At least one hook handle portion 31 in the hook portion 30 passes through the hook movable groove 40 and is exposed outside the body 10 of the pick-and-place device; the first end of the piston moving portion 50 is connected to the hook portion 30, and the second end of the piston moving portion 50 is located in the negative pressure cavity 70 and can move along the inner wall of the negative pressure cavity 70; the negative pressure cavity 70 is provided in the internal cavity 11, the first end of the negative pressure cavity 70 abuts against the second end of the guide rail portion 60, and the second end of the negative pressure cavity 70 is fixedly connected to the inner wall of the second end of the pick-and-place device body 10; one end of the suction nozzle portion 80 is fixedly provided on the outer wall of the second end of the pick-and-place device body 10.
[0029] In this embodiment, the adsorption-type device for picking up and placing dental X-ray films is used to adsorb dental X-ray films 100. A dental X-ray film refers to a standard intraoral film, often simply called a dental film. Teeth appear as white radiopaque images on the film, and one film can display images of 3 to 4 teeth. Currently, when acquiring dental X-ray images of adults, the film is placed inside the mouth on one side of the tooth to be photographed, and the adult holds it down with their finger. Generally, the film is placed vertically. However, this method is not suitable for children. When acquiring dental X-ray images of some young children, they cannot hold the film down with their fingers and maintain its vertical position.
[0030] When using the suction-type dental X-ray film placement device described in this application, the user first places the dental film at the suction nozzle 80, then places the user's thumb at the pressing part 20, and hooks the hook part 30 with the index and middle fingers, thereby driving the piston movement part 50 to move along the guide rail part 60. Specifically, the hook part 30 drives the piston movement part 50 to move towards the first end of the placement device body 10, thereby changing the pressure in the negative pressure chamber 70 to achieve suction of the dental X-ray film by the suction nozzle 80. Afterwards, the user places the end of the suction-type dental X-ray film placement device with the suction nozzle 80 attached into the mouth of the user to be tested, such as a child, and positions it on one side of the tooth to be photographed. If the outer wall and the entire placement device body 10 have been disinfected, the user to be tested can bite down on the outer wall of the placement device body 10. As can be seen, through the above method, the suction-type pick-and-place device for dental X-ray films described in this application replaces the user's fingers to fix the dental film to one side of the tooth to be photographed by the user, which facilitates other users to assist the user in fixing the dental film.
[0031] In one embodiment, such as Figure 1 and Figure 2 As shown, the guide rail section 60 includes an inner wall fixing structure 61, a connecting rod 62, and a hook movable guide rail structure 63, all disposed within the internal cavity 11. The first end of the inner wall fixing structure 61 is fixed to the inner wall of the first end of the pick-and-place device body 10, and the second end of the inner wall fixing structure 61 is fixedly connected to the first end of the connecting rod 62. The second end of the connecting rod 62 is fixedly connected to the first end of the hook movable guide rail structure 63. The second end of the hook movable guide rail structure 63 abuts against the first end of the negative pressure cavity 70.
[0032] In this embodiment, in order to enable the part of the hook portion 30 located inside the internal cavity 11 to move, the guide rail portion 60 provided inside the internal cavity 11 can be configured as an inner wall fixing structure 61, a connecting rod 62 and a hook movable guide rail structure 63 connected in sequence. The inner wall fixing structure 61 is a fixing structure used to ensure the overall structural stability of the guide rail 60 (its outer diameter is slightly smaller than the diameter of the internal cavity 11, which can be understood as the inner diameter of the pick-and-place device body 10), and its first end is fixedly connected to the inner wall of the first end of the pick-and-place device body 10; the connecting rod 62 serves as an extension and connection structure of the inner wall fixing structure 61 and the hook movable guide rail structure 63. In specific implementation, it is not necessary to set the connecting rod 62 as a cylindrical structure with the same outer diameter as the inner wall fixing structure 61, but it can be set as a multi-connecting rod structure including multiple small outer diameter cylindrical structures; the hook movable guide rail structure 63 serves as the core structure of the motion guide rail of the hook part 30, and it can be set as including at least two linear guide rail structures. The hook movable guide rail structure 63 with the above structure enables the hook part 30 to move linearly along the hook movable guide rail structure 63.
[0033] In one embodiment, such as Figures 1-3 As shown, the hook part 30 also includes a slide rail connection part 32, which is sleeved on the hook movable guide rail structure 63.
[0034] In this embodiment, in order to function on the hook movable guide rail structure 63, the hook portion 30, in addition to having at least one hook handle portion 31, also needs to be provided with a slide rail connecting portion 32. For example, when the hook movable guide rail structure 63 is configured to include two linear guide rail structures, the middle part of the slide rail connecting portion 32 can be configured as a figure-eight structure to fit onto the two linear guide rail structures of the hook movable guide rail structure 63 respectively. Moreover, by fixing one end of the hook handle portion 31 to the slide rail connecting portion 32, when the user's finger hooks the hook handle portion 31 and moves, it can also drive the slide rail connecting portion 32 to move linearly along the hook movable guide rail structure 63.
[0035] In one embodiment, such as Figures 1-4 As shown, there are two hook movable slots 40, which are respectively referred to as the first hook movable slot 41 and the second hook movable slot 42. The first hook movable slot 41 and the second hook movable slot 42 are through slots provided on the outer wall of the body 10 of the picking and placing device, and the first hook movable slot 41 and the second hook movable slot 42 are arranged facing each other.
[0036] In this embodiment, the hook movable groove 40 serves as a movement stroke limiting and guiding structure for the hook handle portion 31 in the hook part 30. Two grooves can be specifically provided, respectively designated as the first hook movable groove 41 and the second hook movable groove 42. Furthermore, when the pick-and-place device body 10 is configured as a cylindrical structure (i.e., the cross-section of the pick-and-place device body 10 is annular), the first hook movable groove 41 and the second hook movable groove 42 can be arranged facing each other, and the length of the first movable groove corresponding to the first hook movable groove 41 and the length of the first movable groove corresponding to the second hook movable groove 42 are equal. To accommodate the movement trajectory of the hook handle portion 31, both the first hook movable groove 41 and the second hook movable groove 42 can be through grooves provided on the outer wall of the pick-and-place device body 10, allowing the hook handle portion 31 to pass through the first hook movable groove 41 and the second hook movable groove 42, thereby protruding outside the pick-and-place device body 10.
[0037] In one embodiment, such as Figures 1-3 As shown, the hook portion 30 includes two hook handle portions 31, which are respectively referred to as the first hook handle portion 311 and the second hook handle portion 312. One end of the first hook handle portion 311 is connected to the slide rail connecting portion 32, the first hook handle portion 311 passes through the first hook movable groove 41 and the other end of the first hook handle portion 311 is exposed outside the body 10 of the pick-and-place device. One end of the second hook handle portion 312 is connected to the slide rail connecting portion 32, the second hook handle portion 312 passes through the second hook movable groove 42 and the other end of the second hook handle portion 312 is exposed outside the body 10 of the pick-and-place device.
[0038] In this embodiment, when there are two hook movable slots 40, which are respectively referred to as the first hook movable slot 41 and the second hook movable slot 42, the corresponding number of hook handle portions 31 included in the hook portion 30 can also be two, which are respectively referred to as the first hook handle portion 311 and the second hook handle portion 312. For example, referring to the above example, when the middle part of the slide rail connecting portion 32 can be set into a figure-eight structure to be respectively fitted onto the two linear guide rail structures of the hook movable guide rail structure 63, one end of the first hook handle portion 311 is connected to the top end of the figure-eight structure of the slide rail connecting portion 32, and passes through the first hook movable slot 41, so that the other end of the first hook handle portion 311 is exposed outside the body 10 of the pick-and-place device; one end of the second hook handle portion 312 is connected to the bottom end of the figure-eight structure of the slide rail connecting portion 32, and passes through the second hook movable slot 42, so that the other end of the second hook handle portion 312 is exposed outside the body 10 of the pick-and-place device.
[0039] When the user's thumb is placed on the pressing part 20, and the index finger hooks the first hook handle part 311 of the hook part 30, and the middle finger hooks the second hook handle part 312 of the hook part 30, the index and middle fingers apply force, causing the hook part 30 to drive the piston movement part 50 to move towards the first end of the pick-and-place device body 10, thereby changing the pressure in the negative pressure chamber 70 to achieve the adsorption of the dental X-ray film by the suction nozzle part 80. The symmetrical double handle design makes it easier for the user to apply force to adsorb the dental film.
[0040] In one embodiment, such as Figures 1-3 As shown, the piston moving part 50 includes a piston connecting rod 51 and a piston head 52; the first end of the piston connecting rod 51 is fixedly connected to the slide rail connecting part 32, and the second end of the piston connecting rod 51 is fixedly connected to the piston head 52.
[0041] In this embodiment, the piston moving part 50, as an important structure that can change the pressure inside the negative pressure cavity 70, needs to move synchronously with the hook part 30 on the one hand, and on the other hand, it can block the first end inside the negative pressure cavity 70 so that it can be combined with other items or structures to change the pressure inside the negative pressure cavity 70. To meet the above requirements, it can be configured to include a piston connecting rod 51 and a piston head 52. The first end of the piston connecting rod 51 is fixedly connected to the slide rail connecting part 32, so that when the slide rail connecting part 32 is driven by the hook part 30, it synchronously drives the piston connecting rod 51 to move, thereby simultaneously driving the piston head 52 fixed on the second end of the piston connecting rod 51 (the piston head 52 on the second end of the piston moving part is located inside the negative pressure cavity 70 and can move along the inner wall of the negative pressure cavity 70). Among them, by the movement of the piston head 52 along the inner wall of the negative pressure cavity 70, negative pressure can be generated and the dental plate can be adsorbed.
[0042] In one embodiment, such as Figure 1 and Figure 2 As shown, the inner diameter of the negative pressure chamber 70 is larger than the maximum outer diameter of the piston head 52, and the maximum outer diameter of the piston head 52 is larger than the maximum outer diameter of the piston connecting rod 51.
[0043] In this embodiment, in order for the piston head 52 on the second end of the piston moving part 50 to basically block the first end inside the negative pressure cavity 70, the inner diameter of the negative pressure cavity 70 can be made larger than the maximum outer diameter of the piston head 52. Specifically, the inner diameter of the negative pressure cavity 70 is slightly larger than the maximum outer diameter of the piston head 52 (e.g., the difference between the inner diameter of the negative pressure cavity 70 and the maximum outer diameter of the piston head 52 is 0.1-0.5 mm). When the piston head 52 moves along the inner wall of the negative pressure cavity 70 toward the first end of the pick-and-place device body 10, the pressure inside the negative pressure cavity 70 is changed to achieve the adsorption of the dental X-ray film by the suction nozzle 80.
[0044] Furthermore, when the piston head 52 moves along the inner wall of the negative pressure chamber 70 toward the second end of the pick-and-place device body 10, in order to avoid the piston connecting rod 51 obstructing the movement of the piston head in the negative pressure chamber 70, the maximum outer diameter of the piston head 52 can be greater than the maximum outer diameter of the piston connecting rod 51.
[0045] In one embodiment, such as Figure 1 and Figure 2 As shown, the distance between the piston connecting rod 51 and the inner wall of the pick-and-place device body 10 is less than the distance between the hook movable guide rail structure 63 and the inner wall of the pick-and-place device body 10.
[0046] In this embodiment, since the first end of the piston connecting rod 51 is connected to the slide rail connecting part 32, in order to avoid the piston connecting rod 51 obstructing the movement of the entire piston moving part 50 during the movement of the slide rail connecting part 32, the distance between the piston connecting rod 51 and the inner wall of the pick-and-place device body 10 can be set to be smaller than the distance between the hook movable guide rail structure 63 and the inner wall of the pick-and-place device body 10. For example, when the hook movable guide rail structure 63 is set to include two parallel linear guide rail structures with a certain distance, when the hook movable guide rail structure 63 with the above structure is used and the slide rail connecting part 32 is sleeved on the two linear guide rail structures, the outer diameter of the piston connecting rod 51 can be set to be smaller than the distance between the two linear guide rail structures (so that the distance between the piston connecting rod 51 and the inner wall of the pick-and-place device body 10 is smaller than the distance between the hook movable guide rail structure 63 and the inner wall of the pick-and-place device body 10). When the hook part 30 can move linearly along the hook movable guide rail structure 63, the piston connecting rod 51 will not collide with the hook movable guide rail structure 63, thus not affecting the movement of the entire piston moving part 50.
[0047] In one embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the pressing part 20 includes a pressing platform part 21 and a pressing platform connecting rod 22. The pressing platform part 21 is fixedly connected to the outer wall of the first end of the picking and placing device body 10 through the pressing platform connecting rod 22.
[0048] In this embodiment, the pressing part 20 serves as the placement point for the user's thumb in the suction-type pick-and-place device for dental X-ray films. Specifically, the pressing platform part 21 can be configured as a cylindrical structure with a certain thickness, and the pressing platform connecting rod 22 can be configured as a cylindrical structure with an outer diameter smaller than the minimum outer diameter of the pressing platform part 21. This pressing part structure not only ensures structural stability but also facilitates its use as a fixing point for the user's thumb.
[0049] In one embodiment, such as Figure 1 and Figure 2 As shown, the suction nozzle part 80 includes a suction nozzle connecting rod 81 and a suction nozzle structure 82. The suction nozzle structure 82 is fixedly connected to the outer wall of the second end of the pick-and-place device body 10 through the suction nozzle connecting rod 81. The suction nozzle connecting rod 81 communicates with the negative pressure cavity 70. From the end of the suction nozzle structure 82 connected to the suction nozzle connecting rod 81 to the direction away from the suction nozzle connecting rod 81, the suction nozzle structure 82 is an enlarged diameter structure.
[0050] In this embodiment, to facilitate the placement of the suction nozzle 80, which adsorbs the dental film, into the mouth of the user to be tested, the suction nozzle connecting rod 81 can be configured as an "L" shape, such that the axis of the suction nozzle 80 along its length is perpendicular to the axis of the pick-and-place device body 10 along its length. This configuration allows the suction nozzle structure 82 to more easily enter the user's mouth relative to the pick-and-place device body 10, and to place the dental film on one side of the tooth to be photographed. Moreover, from the end of the suction nozzle structure 82 connected to the suction nozzle connecting rod 81 to the direction away from the suction nozzle connecting rod 81, the suction nozzle structure 82 has an enlarged diameter structure, so that the end of the suction nozzle structure 82 that contacts the dental film (i.e., the end of the suction nozzle structure 82 away from the suction nozzle connecting rod 81) has a larger adsorption area, which makes the adsorption and fixation of the dental film more stable.
