[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] According to the first aspect, such as Figure 1-3 As shown, one embodiment provides a card clip detection device, including an imaging device (not shown) and a movable platform 100 disposed at the lower end of the lens of the imaging device.

[0032] The imaging device has a lens for observing the mounting hole on the clip to detect capillaries within the mounting hole. In this embodiment, the imaging device is a microscope. In other embodiments, the imaging device can also be a camera or other observation device.

[0033] The mobile platform 100 is disposed at the lower end of the lens. The mobile platform 100 includes a fixed part 110 and a first movable part 120, which is movably connected to the fixed part 110. The specific shapes of the fixed part 110 and the first movable part 120 can be block-shaped or plate-shaped. In this embodiment, both the fixed part 110 and the first movable part 120 are plate-shaped structures to facilitate the placement of a clip. In other embodiments, the shape can be determined according to the specific shape of the object to be tested. The movable connection can be varied. In this embodiment, the first movable part 120 and the fixed part 110 are slidably connected. Specifically, one of the fixed part 110 and the first movable part 120 is provided with a fixed rail, and the other is provided with a sliding rail, which slidably engages within the groove of the fixed rail.

[0034] The first movable part 120 is provided with a positioning structure 123 for supporting the clip. The positioning structure 123 is used to fix the clip in a preset position so that a fixing hole in the clip is aligned with the lens. The positioning structure 123 can be an L-shaped positioning structure 123, including two positioning blocks located on the right-angled sides of the L-shape, for positioning by contacting the two sides of the clip. In this embodiment, the positioning structure 123 includes positioning blocks arranged on the left and right. In other embodiments, the positioning structure 123 can also be a positioning groove provided on the first movable part 120, using the shape of the positioning groove to adapt to the outer peripheral shape of the clip for positioning.

[0035] The purpose of setting the positioning structure 123 is to position the clip at a preset position on the first movable part 120. This preset position can be determined in advance so that after the clip is positioned by the positioning structure 123, one of its fixing holes can be aligned with the lens, making it easier to inspect the fixing hole. It is also more convenient to subsequently inspect the other fixing holes by moving the first movable part 120.

[0036] According to the clip detection device of the above embodiment, the positioning structure 123 of the moving platform 100 can accurately fix the clip in a preset position, aligning a fixing hole with the lens, thus simplifying the process of manually adjusting the clip position; the movable connection design between the first movable part 120 and the fixed part 110 allows the clip to move smoothly, facilitating the detection of capillaries in each fixing hole one by one. The above technical solution, through the coordinated operation of the imaging device and the moving platform 100, can solve the problems of low efficiency and cumbersome operation in manual detection.

[0037] In some embodiments, such as Figure 1-2 As shown, the first movable part 120 can move linearly along a first direction, and the linear movement direction is parallel to the arrangement direction of the plurality of fixing holes of the clip. In this embodiment, the first direction has been shown in the figure. Since the direction of the plurality of fixing holes on the clip is arranged along the first direction, the first movable part 120 also moves along the first direction to facilitate the inspection of the fixing holes one by one.

[0038] In other embodiments, the first movable part 120 may also move in other directions, and the movement trajectory may be arc-shaped or other curved. The specific movement trajectory can be determined according to the arrangement shape of the parts to be detected on the test piece.

[0039] In some embodiments, such as Figure 1-3 As shown, the first movable part 120 includes a main body 121 and a second movable part 122. The second movable part 122 is movably connected to the main body 121 and can move linearly along a second direction. The second direction is orthogonal to the first direction, and the second movable part 122 is used to carry the card holder.

[0040] The main body 121 may be provided with a sliding rail extending in a first direction, which slides in cooperation with a fixed rail provided on the fixed part 110 to realize linear movement of the first movable part 120 relative to the fixed part 110 in the first direction. The connection between the second movable part 122 and the main body 121 may be a sliding connection. The second movable part 122 is provided with a sliding rail extending in a second direction, and the main body 121 is also provided with a fixed rail extending in the second direction. The two cooperate to realize movement of the second movable part 122 in the second direction.

[0041] In the above configuration, the second movable part 122 for carrying the card holder can not only move along the second direction, but also move along the first direction with the main body part 121, so as to move the position of the card holder and align the card holder with the lens.

[0042] In other embodiments, the second direction may also form an acute angle with the first direction.

[0043] In some embodiments, such as Figures 3-6 As shown, the clamp detection device includes a drive mechanism 200, which includes a drive member 210, a first transmission member 220, and a second transmission member 230. The first transmission member 220 is fixedly connected to the fixed part 110, and the second transmission member 230 is fixedly connected to the second movable part 122. The drive member 210 is disposed on the main body 121 and is simultaneously connected to the first transmission member 220 and the second transmission member 230 to drive the second movable part 122 to move in a first direction and / or a second direction.

[0044] The drive mechanism 200 can be either electric or manual. For an electric drive, the drive element 210 can be a motor or a telescopic rod. For example, when the drive element 210 is a motor, the motor can be equipped with gears or a timing pulley; correspondingly, the first transmission element 220 and the second transmission element 230 can be racks or pinions, or the first transmission element 220 and the second transmission element 230 can be timing belts. For a manual drive, the drive element 210 can be a gear or timing pulley that is manually rotated.

[0045] In some embodiments, such as Figures 3-6 As shown, the driving member 210 may include a first rotating part 211 and a second rotating part 212. The first rotating part 211 and the second rotating part 212 are respectively connected to the first transmission member 220 and the second transmission member 230. During the rotation process, the first rotating part 211 moves relative to the first transmission member 220 along a first direction, and the second rotating part 212 moves relative to the second transmission member 230 along a second direction.

[0046] The first transmission member 220 and the second transmission member 230 can be racks, and the first rotating part 211 and the second rotating part 212 can be gears. The gear meshes with the rack, and the gear drives the rack to move by rotating, or the gear moves along the rack by rotating itself. In this embodiment, the first rotating part 211 moves along the first rack during its rotation, that is, it moves in the first direction; the second rotating part 212 drives the rack to move in the second direction during its rotation.

[0047] The drive unit 210 also includes a rotating shaft 213. A first rotating part 211 and a second rotating part 212 are axially spaced on the rotating shaft 213. One of the first rotating part 211 and the second rotating part 212 is fixedly connected to the rotating shaft 213 and can rotate with the rotating shaft 213, while the other is rotatable relative to the rotating shaft 213. The fact that both the first rotating part 211 and the second rotating part 212 are located on the rotating shaft 213 simplifies the drive mechanism 200, reduces its space requirement, and facilitates operation. In this embodiment, the first rotating part 211 is fixedly connected to the rotating shaft 213, and the second rotating part 212 is a gear with a central hole, which is fitted onto the rotating shaft 213 through the central hole and can rotate relative to the rotating shaft 213.

[0048] Furthermore, the driving component 210 may also include a first knob 214 and a second knob 215. The first knob 214 is fixedly connected to the rotating shaft 213 to drive the first rotating part 211 to rotate, and the second knob 215 is fixedly connected to the second rotating part 212 to drive the second rotating part 212 to rotate. By rotating the first knob 214 and the second knob 215, the operator can conveniently drive the second movable part 122 to move along the first direction and the second direction, respectively.

[0049] In other embodiments, the first transmission member 220 and the second transmission member 230 may also be synchronous belts, and correspondingly, the first rotating part 211 and the second rotating part 212 are pulleys.

[0050] In some embodiments, such as Figure 7As shown, the second movable part 122 is located above the fixed part 110. The fixed part 110 is provided with a first light-transmitting part 111, and the second movable part 122 is provided with a second light-transmitting part 1221. During the movement of the second movable part 122 relative to the fixed part 110, the second light-transmitting part 1221 and the first light-transmitting part 111 overlap at least partially in the vertical direction.

[0051] The first light-transmitting part 111 and the second light-transmitting part 1221 can be light-transmitting plates made of light-transmitting materials such as glass or resin, or they can be light-transmitting through holes provided on the fixing part 110. In this embodiment, the first light-transmitting part 111 is a through hole provided on the fixing part 110, and the second light-transmitting part 1221 is a light-transmitting plate to facilitate the placement of the clip.

[0052] When inspecting the capillary of a clip using imaging devices such as microscopes, lighting conditions are crucial. The arrangement of the first light-transmitting part 111 and the second light-transmitting part 1221 allows light to shine from one side of the fixed plate onto the clip on the second movable part 122, providing a clearer view of the capillary for the operator. In other embodiments, a light source can be provided below the fixed part 110 or the second movable part 122. The light emitted by this light source can pass through the light-transmitting part and illuminate the clip, resulting in a clearer image during inspection. This allows for accurate assessment of the capillary's cleanliness and the presence of blockages, breaks, or other problems.

[0053] In some embodiments, the clip detection device may further include a capillary cleanliness determination device. The determination device receives a capillary image captured by an imaging device and compares it with pre-imported capillary samples of different cleanliness levels to determine the cleanliness of the detected capillary. When the cleanliness does not meet a preset standard, the device prompts the operator to replace or wipe the capillary.

[0054] According to the second aspect, one embodiment provides a mobile platform 100 for card holder detection, which has the same structure as the mobile platform 100 in any of the above embodiments, and will not be described again here.

[0055] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
