Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a verification device and imaging system. Background Technology

[0002] In the manufacturing process of lithium batteries, sodium batteries, and other types of batteries, CT (Computed Tomography) technology is sometimes used for inspection. For example, after the bare cell is assembled into the casing, CT equipment can be used to detect whether the tabs have been folded or deformed.

[0003] For CT equipment, sometimes a calibration device (including a ruby ​​probe or other type of object to be scanned) is needed for the CT equipment to scan and form three-dimensional data. The distance between different objects to be scanned can form a size model. The calibration personnel can calculate the indication error of the CT equipment by comparing the above size model with the measurement value obtained by the coordinate measuring system.

[0004] Due to limitations in size and weight, the aforementioned calibration devices can only provide a limited number of dimensional models when facing multi-point measurement needs, resulting in a large overall number of calibration devices required and a high overall calibration cost. Utility Model Content

[0005] The main objective of this application is to propose a verification device and imaging system that can help reduce the overall verification cost.

[0006] To achieve the above objectives, the verification device proposed in this application is used to verify imaging equipment. The verification device includes a scanned object, a mounting base, and a connecting assembly. The scanned object is used for scanning and imaging by the imaging equipment, and the scanned object is mounted on the mounting base. A part of the connecting assembly is detachably connected to the mounting base, and another part of the connecting assembly is used to connect to the imaging equipment.

[0007] When the calibration device provided in this application is in use, the object to be scanned can be connected to the imaging device through the mounting base and the connecting components. The mounting base and the connecting components can each be made smaller. When facing multi-point measurement requirements, the calibration device can be used to connect to different mounting bases, which is beneficial to provide more size models. Thus, the calibration device can retain the original connecting components, which is beneficial to reduce the overall calibration cost.

[0008] In some implementations, the connection assembly includes a connection plate and a connection shaft, a portion of which is detachably connected to a mounting base, and another portion of which is detachably connected to the connection shaft, which is used to connect to an imaging device.

[0009] At this point, the connecting plate and the connecting shaft are detachably connected. The calibration device can be used to connect to different connecting shafts to change the installation position of the object to be scanned. Thus, the calibration device can be used for different imaging devices and can also reduce the overall calibration cost by retaining the original connecting plate.

[0010] In some implementations, the edge of the connecting plate is provided with a ring plate, which extends along the circumferential direction of the connecting plate, and at least part of the mounting seat is accommodated in the inner space of the ring plate.

[0011] At this point, the mounting base can be accommodated in the inner space of the ring plate, thereby quickly achieving preliminary positioning, which is beneficial to the installation and positioning efficiency of the mounting base.

[0012] In some implementations, at least a portion of the outer peripheral wall of the mounting base is spaced apart from the inner wall of the ring plate; the calibration device also includes an adjusting member, one end of which is connected to the ring plate and the other end of which abuts against the outer peripheral wall of the mounting base; the adjusting member is configured to change position along the thickness direction of the ring plate so that the mounting base moves along the surface of the connecting plate.

[0013] At this point, the adjusting component can change its position along the thickness direction of the ring plate, thereby changing the position of the mounting base relative to the connecting plate and the connecting shaft, which helps to improve the positional accuracy of the mounting base.

[0014] In some implementations, the inner wall of the ring plate is provided with a threaded hole, which extends along the thickness direction of the ring plate; the adjusting component includes a threaded rod, the outer peripheral wall of which is provided with an external thread, the external thread being threadedly connected to the threaded hole, and the other end of the threaded rod being used to abut against the outer peripheral wall of the mounting base.

[0015] At this point, the adjusting component can change its position along the thickness direction of the ring plate through the threaded connection between the threaded rod and the threaded hole, which is beneficial for smoothly adjusting the position of the mounting seat and thus further improving the positional accuracy of the mounting seat.

[0016] In some implementations, the outer peripheral wall of the mounting base is provided with a recess, and the end of the adjusting member extends into the recess and abuts against the wall of the recess.

[0017] At this point, the end of the adjusting component extends into the recess, which helps to limit the movement of the mounting seat in directions other than the thickness direction of the ring plate, thereby improving the position adjustment efficiency and position accuracy of the mounting seat.

[0018] In some implementations, the mounting base has a first mounting hole on the side facing the connecting plate, and the connecting plate has a second mounting hole on the surface facing the mounting base; the calibration device also includes a first fixing member, one end of which is accommodated in the first mounting hole, and the other end of which is accommodated in the second mounting hole, and the fixing member fixes the mounting base and the connecting plate together.

[0019] At this time, with the positional accuracy of the mounting base improved by the adjusting component, the first mounting hole and the second mounting hole can each achieve a higher fitting accuracy with the hole and shaft of the first fixing member. This helps the mounting base maintain a high positional accuracy after being fixed by the first fixing member, and also helps improve the installation efficiency of the first mounting hole and the second mounting hole with the first fixing member.

[0020] In some implementations, the side of the connecting plate has at least one notch; when projected along the thickness direction of the connecting plate, at least part of the mounting base is located within the notch.

[0021] At this point, the user can hold the mounting base through the notch on the side of the connecting plate, which helps improve the efficiency of mounting base assembly and disassembly.

[0022] In some implementations, the mounting base has at least one groove on the side facing the connecting plate; when projected along the thickness direction of the connecting plate, at least part of the groove overlaps with the notch.

[0023] At this point, the mounting base can achieve weight reduction through the grooves, and further improve the installation and removal efficiency of the mounting base by at least partially overlapping the grooves with the notches.

[0024] In some implementations, the verification device further includes an outer casing connected to a mounting base or connecting assembly; the object to be scanned is housed within the outer casing, which is configured to allow the imaging beam of the imaging device to pass through so that the object to be scanned is detected.

[0025] At this time, the object to be scanned is placed inside the outer cover, which helps to prevent the object to be scanned from being damaged by collisions with external objects; the outer cover is configured to allow the imaging beam of the imaging device to pass through so that the object to be scanned can be scanned, which helps to improve the imaging accuracy of the object to be scanned in the imaging device.

[0026] In some implementations, the calibration apparatus further includes an outer cover connected to a mounting base or connecting assembly; the object to be scanned is housed within the outer cover, which is configured to allow the imaging beam of the imaging device to pass through so that the object to be scanned is detected; a portion of the mounting base is housed in the inner space of the annular plate, and another portion of the mounting base is housed within the outer cover; the annular plate abuts against the opening portion of the outer cover along the thickness direction of the connecting plate.

[0027] At this point, the object to be scanned is housed within the outer casing, which helps prevent damage from collisions with external objects. The outer casing is configured to allow the imaging beam of the imaging device to pass through so that the object to be scanned can be detected, thus improving the imaging accuracy of the object in the imaging device. In addition, a portion of the mounting base is housed within the outer casing, and the annular plate abuts against the opening of the outer casing along the thickness direction of the connecting plate. The mounting base and the annular plate can limit the movement of the outer casing, thereby improving the installation stability of the outer casing.

[0028] In some implementations, the projection is made along the thickness direction of the connecting plate, and the outer contour of the mounting base is set as a polygon; the ring plate abuts at least two sides of the outer contour of the mounting base, and / or the outer cover abuts at least two sides of the outer contour of the mounting base.

[0029] At this point, for the verification device to be rotated to facilitate obtaining the overall model, the ring plate should at least abut against at least two sides of the outer contour of the mounting base, which is beneficial to improving the positional stability of the mounting base during rotation; the outer cover should at least abut against at least two sides of the outer contour of the mounting base, which is beneficial to improving the positional stability of the outer cover during rotation.

[0030] In some implementations, the connecting assembly also includes a base, a portion of which is connected to the end of the connecting shaft away from the connecting plate, and another portion of which is used to connect to the imaging device.

[0031] At this point, the base provides a larger installation area relative to the connecting shaft, and the calibration device is able to improve the connection stability with the imaging equipment by using the base.

[0032] In some implementations, the base has a receiving groove on the side facing the connecting shaft, the connecting shaft extends into the receiving groove, and the outer peripheral wall of the connecting shaft abuts against the side wall of the receiving groove.

[0033] At this point, the outer peripheral wall of the connecting shaft abuts against the side wall of the receiving groove, which helps to improve the overall stability of the calibration device.

[0034] In some implementations, a protrusion is provided on the side of the base facing away from the connecting shaft. The protrusion is used to be embedded into the imaging device, and the side wall of the protrusion and the surface of the base facing away from the connecting shaft are used to abut against the imaging device.

[0035] At this point, the raised sidewall and the base surface facing away from the connecting shaft are used to abut against the imaging device, which helps to improve the connection stability between the base and the imaging device.

[0036] This application also provides an imaging system, which includes an imaging device and the aforementioned calibration apparatus.

[0037] When the imaging system provided in this application is in use, the object to be scanned can be connected to the imaging device through the mounting base and the connecting components. The mounting base and the connecting components can each be made smaller. When facing multi-point measurement requirements, the calibration device can be used to connect to different mounting bases, which is conducive to providing more size models. Thus, the calibration device can retain the original connecting components, which is conducive to reducing the overall calibration cost. Attached Figure Description

[0067] In the manufacturing process of lithium batteries, sodium batteries, and other types of batteries, CT (Computed Tomography) technology is sometimes used for inspection. For example, after the bare cell is assembled into the casing, CT equipment can be used to detect whether the tabs have been folded or deformed.

[0068] For CT equipment, sometimes a calibration device (including a ruby ​​probe or other type of object to be scanned) is needed for the CT equipment to scan and form three-dimensional data. The distance between different objects to be scanned can form a size model. The calibration personnel can calculate the indication error of the CT equipment by comparing the above size model with the measurement value obtained by the coordinate measuring system.

[0069] Due to limitations in size and weight, the aforementioned calibration devices can only provide a limited number of dimensional models when facing multi-point measurement needs, resulting in a large overall number of calibration devices required and a high overall calibration cost.

[0070] Based on the above considerations, and in order to reduce the overall verification cost, this application proposes a verification device and an imaging system. The verification device and imaging system, when in use, can retain some of the original structure, thereby helping to reduce the overall verification cost.

[0071] The verification device and imaging system proposed in this application will now be explained and described in detail with reference to specific implementation methods.

[0072] Reference Figure 1 and Figure 2In one embodiment of this application, the calibration device 100 for calibrating an imaging device includes a scanned object 110, a mounting base 120, and a connecting component 130. The scanned object 110 is used for scanning by the imaging device to form an image, and the scanned object 110 is mounted on the mounting base 120. A part of the connecting component 130 is detachably connected to the mounting base 120, and another part of the connecting component 130 is used for connecting to the imaging device.

[0073] The imaging device can be a CT scanner, X-ray scanner, etc. Taking a CT scanner as an example, the corresponding object to be scanned 110 can include materials such as ruby, sapphire, silicon nitride, and zirconium oxide. In some embodiments, the calibration device 100 can include at least two objects to be scanned 110. Each object to be scanned 110 can include a connecting rod 111 and a target scanning element 112. The connecting rod 111 is mounted on the mounting base 120. The connecting rod 111 can be mounted on the mounting base 120 via threaded connection, plug-in connection, or other means. This can be understood as the object to be scanned 110 being mounted on the mounting base 120 via a detachable method such as threaded connection or plug-in connection. The target scanning element 112 is connected to the end of the connecting rod 111 furthest from the connecting assembly 130. The connecting rod 111 can be made of materials such as metal or carbon fiber, and the target scanning element 112 can be a ruby ​​sphere, sapphire sphere, silicon nitride sphere, zirconium oxide sphere, etc. For example, the object to be scanned 110 can be made of a ruby ​​stylus with a diameter of 4 mm, thus possessing excellent wear resistance and geometric accuracy, enabling it to withstand complex measurement environments and frequent use, thereby ensuring calibration accuracy and operational stability. Furthermore, using ruby ​​to make the target scanning element 112 ensures high stability of its size and shape under different temperature conditions due to ruby's low coefficient of thermal expansion, facilitating the accuracy and reliability of measurement results. Ruby material also offers good economic efficiency and availability, resulting in a high cost-performance ratio.

[0074] In use, the imaging device can scan the object to be scanned 110 (specifically, it can scan the target scanning element 112) and image it by emitting beams of particle or energy layer type.

[0075] Mounting base 120 can be understood as a base for mounting the object to be scanned 110. Mounting base 120 can be made of materials such as metal or plastic; for example, it can be made of AL6061-T6 aluminum. In some embodiments, refer to... Figure 4 The mounting base 120 faces away from the connecting assembly 130 (e.g., Figure 4 The upper side of the first protrusion 1251 and part of the body to be scanned 110 are provided. The side of the first protrusion 1251 facing away from the connecting assembly 130 (e.g.) Figure 4The upper side of the middle part has a second protrusion 1252 and a portion of the body to be scanned 110. The side of the second protrusion 1252 facing away from the connecting assembly 130 (e.g.) Figure 4 The upper side of the mounting base 120 is provided with a portion of the objects to be scanned 110; thus, the mounting base 120 can form a three-step structure, and each object to be scanned 110 can have the same height, so that the objects to be scanned 110 can be divided into three groups; wherein the objects to be scanned 110 on each step are a group, and the arrangement height of each group of objects to be scanned 110 can be set to be the same.

[0076] In some implementations, refer to Figure 5 Eight mounting points can be provided on the side of the first protrusion 1251, four mounting points can be provided on the top surface of the first protrusion 1251, and one mounting point can be provided on the top surface of the second protrusion 1252. Correspondingly, the verification device 100 can include thirteen objects to be scanned 110, which are connected to the aforementioned thirteen mounting points. It is understood that the number of mounting points and objects to be scanned 110 is only an example, and different mounting bases 120 can be provided with different numbers and different arrangements of mounting points.

[0077] The connecting component 130 can be understood as a component that connects the mounting base 120 and the imaging device. For example, the connecting component 130 can mount the mounting base 120 onto the rotating mechanism of the imaging device, thereby driving the object to be scanned 110 to rotate and obtain the overall model of the object to be scanned 110. The connecting component 130 can achieve a detachable connection with the mounting base 120 through threaded connection, plug-in, snap-fit, etc.; furthermore, the connecting component 130 can be connected to the imaging device through threaded connection, plug-in, snap-fit, etc., and this embodiment does not limit this.

[0078] In use, the verification device 100 provided in this embodiment allows the object to be scanned 110 to be connected to the imaging device via the mounting base 120 and the connecting assembly 130. The mounting base 120 and the connecting assembly 130 can each be made smaller in size; for example, in... Figure 1 When the mounting base 120 and the connecting component 130 are stacked, both the mounting base 120 and the connecting component 130 can be made thinner. When facing multi-point measurement requirements, the calibration device 100 can be used to connect to different mounting bases 120, which is beneficial for providing more dimensional models. Thus, the calibration device 100 can retain the original connecting component 130, thereby helping to reduce the overall calibration cost.

[0079] In some implementations, refer to Figure 1 , Figure 3 and Figure 4 The connecting assembly 130 includes a connecting plate 131 and a connecting shaft 133. A portion of the connecting plate 131 is detachably connected to the mounting base 120, for example... Figure 1 The upper side of the connecting plate 131 is detachably connected to the mounting base 120, for example, through threaded connection, plug-in connection, snap-fit, etc.; another part of the connecting plate 131 is detachably connected to the connecting shaft 133, for example... Figure 1 The lower side of the connecting plate 131 is detachably connected to the connecting shaft 133, for example, through threaded connection, plug-in connection, or snap-fit ​​connection. The thickness direction of the connecting plate 131 can be aligned with the axial direction of the connecting shaft 133, for example... Figure 1 The thickness direction of the connecting plate 131 and the axial direction of the connecting shaft 133 are both set in the vertical direction; based on this, one surface of the connecting plate 131 (e.g., Figure 1 The upper side panel of the connecting plate 131 can be detachably connected to the mounting base 120, thereby improving the connection stability of the mounting base 120 through surface contact; in addition, the other side panel of the connecting plate 131 (e.g., Figure 1 The lower side plate of the connecting plate 131 is connected to the axial end face of the connecting shaft 133, thereby improving the connection stability between the connecting plate 131 and the connecting shaft 133.

[0080] Furthermore, the connecting shaft 133 is used to connect to the imaging device. For example, the connecting shaft 133 can be connected to the imaging device by means of threaded connection, plug-in connection, snap-fit ​​connection, etc. In some embodiments, the connecting shaft 133 can be made of metal materials such as SUS304 stainless steel.

[0081] In this embodiment, the connecting plate 131 and the connecting shaft 133 are detachably connected, and the calibration device 100 can be used to change the installation position of the object to be scanned 110 by connecting different connecting shafts 133, for example, changing... Figure 1 The height position of the object to be scanned 110 is determined so that the verification device 100 can be used with different imaging devices and can reduce the overall verification cost by retaining the original connecting plate 131.

[0082] In some implementations, refer to Figure 3 , Figure 4 and Figure 5The connecting plate 131 has an annular plate 132 at its edge, which extends along the circumferential direction of the connecting plate 131, and can be understood as the annular plate 132 wrapping around the connecting plate 131. In some embodiments, the annular plate 132 and the connecting plate 131 can be integrally formed, for example by integral injection molding, integral casting, integral stamping, etc.; of course, the annular plate 132 can also be connected to the connecting plate 131 by welding, plugging, etc., and this embodiment does not limit this. The annular plate 132 and the connecting plate 131 can be made of metal materials such as AL6061-T aluminum alloy, so as to have good mechanical properties and corrosion resistance. In addition, at least a portion of the mounting base 120 is accommodated in the inner space of the annular plate 132, for example, a portion of the mounting base 120 can be accommodated in the inner space of the annular plate 132, or the entire mounting base 120 can be accommodated in the inner space of the annular plate 132.

[0083] In this embodiment, the mounting base 120 can be quickly pre-positioned by being accommodated in the inner space of the ring plate 132, which is beneficial to the installation and positioning efficiency of the mounting base 120.

[0084] In some implementations, refer to Figure 5 and Figure 6 At least a portion of the outer peripheral wall of the mounting base 120 is spaced apart from the inner wall surface of the annular plate 132. This can be understood as the mounting base 120 being movable relative to the annular plate 132 along the thickness direction of the annular plate 132, for example, along... Figure 6 The device moves left and right in the middle. The calibration device 100 also includes an adjusting member 122, one end of which is connected to the ring plate 132, and the other end of which abuts against the outer peripheral wall of the mounting base 120. This can be understood as the adjusting member 122 being installed between the ring plate 132 and the outer peripheral wall of the mounting base 120. The adjusting member 122 is configured to change position along the thickness direction of the ring plate 132, for example, along... Figure 6 The mounting base 120 is moved left and right to change its position, thereby moving along the surface of the connecting plate 131 and changing the position of the mounting base 120 relative to the connecting plate 131 and the connecting shaft 133; for example, to center the mounting base 120 relative to the connecting shaft 133. At least two adjusting members 122 can be spaced apart in the circumferential direction of the annular plate 132 to facilitate multi-directional adjustment of the position of the mounting base 120.

[0085] In this embodiment, the adjusting member 122 can change its position along the thickness direction of the ring plate 132, thereby changing the position of the mounting base 120 relative to the connecting plate 131 and the connecting shaft 133, which helps to improve the positional accuracy of the mounting base 120. For example, the calibration device 100 can rotate by using the connecting shaft 133 as a rotating axis, that is, the rotation axis of the calibration device 100 can coincide with the axis of the connecting shaft 133; in this case, by centering the mounting base 120 relative to the connecting shaft 133, the mounting base 120 is more stable during rotation, thereby reducing the shaking of the object to be scanned 110, which helps to improve the imaging accuracy.

[0086] In some implementations, refer to Figure 7 The adjusting member 122 includes a threaded rod 1221, the outer peripheral wall of which is provided with external threads; this can be understood as at least a portion of the outer peripheral wall of the adjusting member 122 being provided with external threads. Correspondingly, refer to... Figure 8 The inner wall of the ring plate 132 is provided with a threaded hole extending along the thickness direction of the ring plate 132. The external thread of the threaded rod 1221 is threadedly connected to the threaded hole, so that the adjusting member 122 can move from the inside of the ring plate 132 toward the mounting base 120. In addition, the other end of the threaded rod 1221 is used to abut against the outer peripheral wall of the mounting base 120, thereby driving the mounting base 120 to move and adjust the position of the mounting base 120. It can be understood that the threaded hole on the inner wall of the ring plate 132 can penetrate the ring plate 132 along the thickness direction, so as to facilitate the adjustment member 122 being turned from the outside, for example, through the internal hexagonal structure at the end of the adjusting member 122.

[0087] In this embodiment, the adjusting member 122 can change its position along the thickness direction of the ring plate 132 through the threaded connection between the threaded rod 1221 and the threaded hole, which is beneficial to smoothly adjust the position of the mounting base 120 by adjusting the adjusting member 122, thereby further improving the positional accuracy of the mounting base 120.

[0088] In some implementations, refer to Figure 9 , Figure 10 The outer peripheral wall of the mounting base 120 is provided with a recess 123, which can be formed by drilling, hammering, or other methods. The end of the adjusting member 122 extends into the recess 123, and the end of the adjusting member 122 abuts against the wall surface of the recess 123. For example, see... Figure 7The end of the adjusting member can be provided with a rotatable ball that extends into the recess 123. Furthermore, an elastic member can be provided between the ball and the main body of the adjusting member 122. One end of the elastic member is connected to the main body of the adjusting member 122, and the other end is connected to the ball. This elastic member is used to move the ball toward the mounting base 120, thereby pressing against the mounting base 120 or even moving the mounting base 120. (Refer to...) Figure 7 The elastic element can be set as a compression spring.

[0089] In this embodiment, the end of the adjusting member 122 extends into the recess 123, which helps to restrict the movement of the mounting base 120 in directions other than the thickness direction of the ring plate 132, such as restricting the movement in the vertical and horizontal directions and the front and back directions shown in the figure, thereby improving the position adjustment efficiency and position accuracy of the mounting base 120.

[0090] In some implementations, refer to Figure 10 The mounting base 120 has a first mounting hole 124 on the side facing the connecting plate 131, and this first mounting hole 124 can be configured as a through hole; see reference Figure 8 The connecting plate 131 has a second mounting hole 134 on its surface facing the mounting base 120. This second mounting hole 134 can also be configured as a through hole. (Refer to...) Figure 6 , Figure 8 and Figure 10 The calibration device 100 also includes a first fixing member 135. One end of the first fixing member 135 is received in a first mounting hole 124, and the other end of the first fixing member 135 is received in a second mounting hole 134. The fixing member fixes the mounting base 120 and the connecting plate 131 together. For example, the first fixing member 135 can be a screw or bolt, the first mounting hole 124 can be a threaded hole, and the second mounting hole 134 can be a threaded hole or a smooth hole. Of course, the first fixing member 135 can also be a rivet, thereby fixing the mounting base 120 and the connecting plate 131 by riveting.

[0091] In this embodiment, when the positional accuracy of the mounting base 120 is improved by the adjusting member 122, the first mounting hole 124 and the second mounting hole 134 can respectively achieve higher fitting accuracy with the hole shaft of the first fixing member 135. This is beneficial to ensure that the mounting base 120 maintains high positional accuracy after being fixed by the first fixing member 135, and to improve the installation efficiency of the first mounting hole 124 and the second mounting hole 134 with the first fixing member 135.

[0092] In some implementations, refer to Figure 6The connecting shaft 133 may have a third mounting hole at one end facing the connecting plate 131, and the connecting plate 131 may have a fourth mounting hole at one end facing the connecting shaft 133. The calibration device 100 may also include a second fixing member, one end of which is accommodated in the third mounting hole, and the other end of which is accommodated in the fourth mounting hole. The second fixing member may be a screw, bolt, or rivet, etc.

[0093] In some implementations, refer to Figure 8 , Figure 11 The connecting plate 131 has at least one notch 1311 on its side; projected along the thickness direction of the connecting plate 131, at least a portion of the mounting base 120 is located within the notch 1311, for example... Figure 11 A portion of the mounting base 120 covers the notch 1311 from above. The notch 1311 can be formed during the injection molding or casting stage, or it can be subsequently formed by wire cutting, punching, machining, or other methods. This embodiment does not impose any restrictions on this.

[0094] In this embodiment, the user can grasp the mounting base 120 through the notch 1311 on the side of the connecting plate 131, which helps improve the efficiency of assembling and disassembling the mounting base 120. For example, the user's fingers can grasp it through the notch 1311 on the side of the connecting plate 131. Figure 11 The bottom of the device touches the mounting base 120 through the notch 1311, making it easy for the user to hold the mounting base 120.

[0095] In some implementations, refer to Figure 10 , Figure 11 The mounting base 120 has at least one groove 121 on the side facing the connecting plate 131, for example... Figure 10 The bottom of the mounting base 120 is provided with four grooves 121; projected along the thickness direction of the connecting plate 131, for example, projected along the vertical direction in the figure, refer to... Figure 11 At least part of the groove 121 overlaps with the notch 1311, which can be understood as the existence of a groove 121 that communicates with the notch 1311. For example, in the figure, there are two grooves 121 that correspond to and communicate with two notches 1311 respectively. The groove 121 can be formed during the injection molding or casting stage, or it can be formed by subsequent machining or other methods. This embodiment does not limit this.

[0096] In this embodiment, the mounting base 120 can achieve weight reduction through the groove 121; the mounting base 120 can also improve the assembly and disassembly efficiency by overlapping at least part of the groove 121 with the notch 1311. For example, the user's fingers can further abut against the side wall of the groove 121, making it easier to hold the mounting base 120.

[0097] In some implementations, refer to Figure 1 , Figure 2 and Figure 12 The calibration device 100 also includes an outer cover 140, which is connected to the mounting base 120 or the connecting assembly 130. In some embodiments, the outer cover 140 can be connected to the mounting base 120, wherein the bottom periphery of the outer cover 140 can be fixedly connected to the outer peripheral wall of the mounting base 120, for example, by fasteners such as screws, for example, by using eight screws for locking, to ensure that the connection between the outer cover 140 and the mounting base 120 is firm and reliable. In addition, the object to be scanned 110 is housed within the outer cover 140, which is configured to allow the imaging beam of the imaging device to pass through so that the object to be scanned 110 can be scanned; for example, referring to Figure 12 The outer cover 140 can be made of five transparent acrylic sheets as the main material. The five transparent acrylic sheets are bonded together with industrial adhesive to ensure the structural stability of the assembled outer cover 140. When the outer cover 140 is made of a light-transmitting material (such as the aforementioned transparent acrylic sheets), the user can directly observe the state of the object to be scanned 110 inside with the naked eye through the light-transmitting outer cover 140, which is conducive to timely detection and handling of possible abnormalities.

[0098] In this embodiment, the object to be scanned 110 is housed within the outer cover 140, which helps to prevent the object to be scanned 110 from being damaged by collisions with external objects; the outer cover 140 is configured to allow the imaging beam of the imaging device to pass through so that the object to be scanned 110 can be scanned, which helps to improve the imaging accuracy of the object to be scanned 110 in the imaging device.

[0099] In some implementations, refer to Figure 1 , Figure 2 and Figure 3 A portion of the mounting base 120 is accommodated in the inner space of the ring plate 132, for example, the lower part of the mounting base 120 is accommodated in the inner space of the ring plate 132 in the figure; another portion of the mounting base 120 is accommodated in the outer cover 140, for example, the upper part of the mounting base 120 is accommodated in the outer cover 140 in the figure; along the thickness direction of the connecting plate 131, for example, along the up and down direction in the figure, the ring plate 132 abuts against the opening portion of the outer cover 140.

[0100] In this embodiment, a portion of the mounting base 120 is housed within the outer cover 140, and the annular plate 132 abuts against the opening portion of the outer cover 140 along the thickness direction of the connecting plate 131. The mounting base 120 and the annular plate 132 can limit the outer cover 140. For example, the mounting base 120 limits the outer cover 140 in the left-right direction as shown in the figure, and the annular plate 132 limits the outer cover 140 in the up-down direction as shown in the figure, thereby improving the installation stability of the outer cover 140.

[0101] In some implementations, refer to Figure 3 , Figure 5 The projection is made along the thickness direction of the connecting plate 131, for example, along the vertical direction shown in the figure. The outer contour of the mounting base 120 is set as a polygon, such as a triangle, quadrilateral, pentagon, hexagon, etc.; it is understood that the corners of the polygon can be set as rounded corners. The ring plate 132 abuts against at least two sides of the outer contour of the mounting base 120. For example, the ring plate 132 is set as a square frame in the figure, so that all four sides of the quadrilateral mounting base 120 can be abutted.

[0102] In some implementations, refer to Figure 1 The outer cover 140 abuts against at least two sides of the outer contour of the mounting base 120. For example, the outer cover 140 is configured as a square cover in the figure, so that all four sides of the quadrilateral mounting base 120 are abutted.

[0103] In the above embodiments, when the calibration device 100 needs to rotate to facilitate obtaining the overall model, such as in a molding device in the form of a CT scanner, the calibration device 100 needs to rotate during CT imaging, for example, rotating 360 degrees about the connecting shaft 133. On one hand, the ring plate 132 abuts against at least two sides of the outer contour of the mounting base 120, which helps to improve the positional stability of the mounting base 120 during rotation. On the other hand, the outer cover 140 abuts against at least two sides of the outer contour of the mounting base 120, which helps to improve the positional stability of the outer cover 140 during rotation.

[0104] In some implementations, refer to Figure 3 , Figure 14 , Figure 15 The connecting assembly 130 also includes a base 150, a portion of which is connected to the end of the connecting shaft 133 away from the connecting plate 131, for example, with Figure 3 The bottom of the central connecting shaft 133 is connected; another part of the base 150 is used to connect with the imaging device, for example, the bottom of the base 150 in the figure can be used to connect with the imaging device.

[0105] In this embodiment, the base 150 provides a larger mounting area relative to the connecting shaft 133, and the calibration device 100 is able to improve the connection stability with the imaging device through the base 150.

[0106] In some implementations, refer to Figure 14The base 150 has a receiving groove 151 on the side facing the connecting shaft 133. For example, the upper side of the base 150 in the figure has a receiving groove 151. The connecting shaft 133 extends into the receiving groove 151, and the outer peripheral wall of the connecting shaft 133 abuts against the side wall of the receiving groove 151, thereby pressing against it in the side wall direction.

[0107] In this embodiment, the outer peripheral wall of the connecting shaft 133 abuts against the side wall of the receiving groove 151, which helps to improve the overall stability of the calibration device 100.

[0108] In some implementations, refer to Figure 15 The base 150 has a protrusion 152 on the side facing away from the connecting shaft 133, for example, the bottom side of the base 150 in the figure has the protrusion 152; the protrusion 152 is used to be embedded into the imaging device, for example, embedded into the mounting groove of the imaging device; the side wall surface of the protrusion 152 and the surface of the base 150 facing away from the connecting shaft 133 are respectively used to abut against the imaging device, for example, the side wall surface of the protrusion 152 abuts against the side wall surface of the mounting groove of the imaging device, and the surface of the base 150 facing away from the connecting shaft 133 abuts against the outer surface of the imaging device.

[0109] In this embodiment, the side wall of the protrusion 152 and the surface of the base 150 facing away from the connecting shaft 133 are respectively used to abut against the imaging device, which helps to improve the connection stability between the base 150 and the imaging device.

[0110] In the above-described embodiment, when using the calibration device 100, the object to be scanned 110 can be first installed onto the mounting base 120. The type and length of the object to be scanned 110 can be selected according to actual measurement requirements. During installation, care should be taken to ensure a secure connection between the object to be scanned 110 and the mounting base 120; for example, a special tool can be used to tighten the object to be scanned 110 to ensure it does not loosen during measurement.

[0111] After this, the outer cover 140 can be placed on the mounting base 120; after ensuring that the periphery of the outer cover 140 is aligned with the mounting base 120, the outer cover 140 is fixed to the mounting base 120 with screws or other fasteners to ensure that the outer cover 140 does not shift or loosen during the measurement process.

[0112] After this, the connecting shaft 133 can be connected to the base 150. After ensuring that the connecting shaft 133 and the base 150 are aligned, the connecting shaft 133 and the base 150 can be fixed with screws or other fasteners to ensure that the connection between the two is stable and reliable.

[0113] After this, the connecting plate 131 can be installed on the other end face of the connecting shaft 133, and the connecting plate 131 and the connecting shaft 133 can be aligned. Then, the connecting plate 131 and the connecting shaft 133 can be fixed with a second fastener such as screws to ensure that the connecting plate 131 remains stable during the measurement process.

[0114] After this, the position of the aforementioned adjusting member 122 can be adjusted to assemble and align the mounting base 120 with the connecting plate 131, and then fix it by the first fixing member 135.
