Description

Technical Field

[0001] This utility model relates to the field of optical inspection equipment, specifically to a cover plate device and an inspection device. Background Technology

[0002] When using optical inspection equipment, the part to be inspected (such as a printed circuit board) is generally placed between a cover plate and a worktable. The cover plate is used to flatten the part to be inspected, and then the camera captures images to check and analyze the product quality. This setup can avoid the local warping of the material of the part to be inspected affecting the image quality of the camera.

[0003] During use, the testing equipment requires the cover plate and the worktable to be aligned and connected. However, after the cover plate is raised and lowered multiple times, there may be a positional shift, causing the cover plate to fail to be properly placed on the worktable, affecting the testing results and posing a safety hazard.

[0005] To achieve the objectives of this utility model, the following technical solution is provided:

[0006] In a first aspect, this utility model provides a cover plate device for a testing equipment, comprising a support assembly and a cover plate assembly. The cover plate assembly is used to move in a first direction and be placed on the support assembly. The space between the cover plate assembly and the support assembly is used to place a component to be tested. One of the support assembly and the cover plate assembly has an alignment member, and the other has an alignment groove. The alignment member is used to extend into the alignment groove. The alignment member has an alignment surface, which is used to slide relative to the inner wall of the alignment groove, so that the support assembly and the cover plate assembly are aligned in a second direction, wherein the first direction and the second direction intersect.

[0007] In one embodiment, the alignment member further includes a bottom surface, a top surface, and a side surface, the bottom surface and the top surface being opposite each other in the first direction, the bottom surface being connected to the support assembly or the cover plate assembly, the side surface being connected to the bottom surface, the alignment surface being connected to the top surface and the side surface at the end away from the bottom surface, and the angle between the side surface and the first direction being smaller than the angle between the alignment surface and the first direction.

[0008] In one embodiment, the alignment groove includes a first sidewall, a second sidewall, and a third sidewall. The second sidewall and the third sidewall are opposite each other in a third direction. The first sidewall connects the second sidewall and the third sidewall. The opening of the alignment groove is opposite to the first sidewall in a second direction. The third direction intersects both the first direction and the second direction. The alignment surface is used to slide relative to the second sidewall, or the alignment surface is used to slide relative to the third sidewall, so that the support assembly and the cover plate assembly are aligned in the third direction.

[0009] In one embodiment, there are multiple alignment members and multiple alignment grooves. The support assembly or the cover plate assembly is provided with at least one alignment member on each of the opposite sides in the second direction, and the multiple alignment members and multiple alignment grooves correspond one-to-one.

[0010] In one embodiment, the support assembly further includes a first transparent plate and a first mounting frame, the first mounting frame being fitted around the perimeter of the first transparent plate; the cover plate assembly further includes a second transparent plate and a second mounting frame, the second mounting frame being fitted around the perimeter of the second transparent plate, and the alignment member is engaged with the alignment groove to align the second transparent plate with the first transparent plate in the second direction.

[0011] The first mounting frame has the alignment groove, the opening of the alignment groove is located on the side of the first mounting frame, and the alignment member is connected to the second mounting frame.

[0012] Alternatively, the second mounting frame has the alignment groove, the opening of which is located on the side of the second mounting frame, and the alignment member is connected to the first mounting frame.

[0013] In one embodiment, the cover plate device further includes a lifting assembly, the cover plate assembly being moved in the first direction and placed on the lifting assembly, the lifting assembly being used to drive the cover plate assembly to move toward or away from the support assembly in the first direction;

[0014] One of the lifting assembly and the cover plate assembly has a guide member and the other has a guide groove. The guide member is for extending into the guide groove. The guide member has a guide surface for contacting and sliding relative to the inner wall of the guide groove, so as to align the lifting assembly and the cover plate assembly in the second direction.

[0015] In one embodiment, the lifting assembly includes a lifting drive mechanism and a mounting platform. The lifting drive mechanism is used to drive the mounting platform to move along the first direction.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0037] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0038] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please refer to Figures 1 to 7 This utility model provides a testing device, including a testing device (not shown) and a cover plate device 100 in this utility model embodiment. The cover plate device 100 includes a support component 10 and a cover plate component 20. The testing device is used to test the part to be tested located between the cover plate component 20 and the support component 10.

[0040] Optionally, the component to be inspected is a printed circuit board (PCB). The inspection equipment is used to inspect the holes on the PCB, for example, it can inspect the holes on the front and back of the PCB. Specifically, holes need to be drilled on both the front and back of a PCB (the holes drilled on the back are referred to as back drills), which are called primary drilling and secondary drilling (secondary drilling is also called back drilling), but the hole diameters are different, with the secondary drilling hole diameter being larger and the primary drilling hole diameter being smaller. Drilling on the front and back sides needs to be done in two separate processes, and whether the secondary drilling hole (larger hole) and the primary drilling hole (smaller hole) are concentric is a key aspect of this process. The inspection equipment can detect parameters such as the concentricity and deviation between the back drilled hole and the front hole, whether the back drilled hole is blocked by foreign objects, and whether there are any missed back drilled holes.

[0041] The inspection device is used to acquire detailed feature images of the part to be inspected. Optionally, the inspection device includes an inspection camera, which can be any one or a combination of CCD (Charge-Coupled Device) cameras, contact linear array (CISC) cameras, CMOS cameras, etc., without any specific limitation.

[0042] Optionally, the detection device also includes a drive mechanism connected to the detection camera and used to drive the detection camera to move relative to the cover plate device 100 to obtain feature images of different positions of the part to be detected.

[0043] Optionally, the testing equipment may also include a stage (not shown), on which the cover plate device 100 is placed.

[0044] The detection equipment in this embodiment of the present invention employs the cover plate device 100, ensuring precise alignment of the cover plate assembly 20 and the support assembly 10. This prevents the cover plate assembly 20 from tilting and colliding with other parts of the detection equipment, thereby improving the safety performance of the detection equipment.

[0045] The cover plate device 100 in the embodiments of this utility model will be described in detail below.

[0046] First, define the direction; please refer to [the relevant documentation]. Figure 1 Z is the first direction, X is the second direction, and Y is the third direction. Optionally, the first direction Z, the second direction X, and the third direction Y intersect each other. Optionally, the first direction Z, the second direction X, and the third direction Y are perpendicular to each other.

[0047] When the detection device is placed on a horizontal plane, the first direction Z can be the direction of gravity, and one of the second direction X and the third direction Y is the length direction of the cover plate device 100 and the other is the width direction of the cover plate device 100, without restriction.

[0048] Please refer to Figures 1 to 7 This utility model provides a cover plate device 100 for use in testing equipment. The cover plate device 100 includes a support component 10 and a cover plate component 20.

[0049] The cover plate assembly 20 is used to move in the first direction Z and be placed on the support assembly 10, and the space between the cover plate assembly 20 and the support assembly 10 is used to place the item to be tested.

[0050] Optionally, the cover plate assembly 20 can be moved manually or mechanically along the first direction Z. Specifically, before testing, the part to be tested is placed on the support assembly 10, and the cover plate assembly 20 is moved toward the support assembly 10 until it is positioned on the support assembly 10, facilitating the testing device's operation. At this time, the cover plate assembly 20 and the support assembly 10 can be in close contact with the upper and lower surfaces of the part to be tested, respectively, or there can be a certain gap between the cover plate assembly 20 and the part to be tested; this is not limited. After testing the part to be tested, the cover plate assembly 20 can be moved manually or mechanically along the first direction Z away from the support assembly 10 to replace the part to be tested.

[0051] One of the support assembly 10 and the cover assembly 20 has an alignment member 31, and the other has an alignment groove 32. The alignment member 31 is for extending into the alignment groove 32. The alignment member 31 has an alignment surface that is used to slide relative to the inner wall of the alignment groove 32 when the cover assembly 20 moves toward the support assembly 10 and is offset relative to the support assembly 10 in the second direction X, so that the support assembly 10 and the cover assembly 20 are aligned in the second direction X.

[0052] The alignment member 31 can be block-shaped, columnar, frustum-shaped, cone-shaped, pyramidal, etc., and there is no specific limitation. When the alignment member 31 extends into the alignment groove 32 to complete the alignment, the inner wall of the alignment groove 32 can be in close contact with the side of the alignment member 31, or there can be a slight gap between the two, to avoid positional deviation of the cover plate assembly 20 relative to the support assembly 10, which would affect the image taking by the detection device.

[0053] Optionally, the support assembly 10 has an alignment member 31, and the cover assembly 20 has an alignment groove 32; or, as Figures 1 to 4 As shown, the support assembly 10 has an alignment groove 32, and the cover plate assembly 20 has an alignment member 31, which is not limited.

[0054] When the cover plate assembly 20 moves toward the support assembly 10 until the alignment member 31 just contacts the support assembly 10, there may be a certain positional offset between them in the second direction X, that is, the alignment member 31 and the alignment groove 32 are not perfectly aligned. At this time, as the cover plate assembly 20 continues to move toward the support assembly 10, the alignment surface can contact and slide relative to the inner wall of the alignment groove 32, guiding the alignment member 31 to slide into the alignment groove 32, so as to achieve the alignment of the support assembly 10 and the cover plate assembly 20 in the second direction X. By setting the alignment surface, the positional error tolerance between the cover plate assembly 20 and the support assembly 10 is improved, and even if there is a certain offset at the beginning, it will not cause the cover plate assembly 20 and the support assembly 10 to fail to align in the end.

[0055] The cover plate device 100 in this embodiment of the present invention comprises a support assembly 10 and a cover plate assembly 20, one of which has an alignment member 31 and the other has an alignment groove 32. When the cover plate assembly 20 moves toward the support assembly 10, and the two are offset in the second direction X, the alignment surface of the alignment member 31 can slide relative to the inner wall of the alignment groove 32 to guide the alignment member 31. This can correct the initial positional deviation in time, prevent the alignment member 31 from failing to extend into the alignment groove 32 and causing the cover plate assembly 20 to tilt, achieve the alignment between the cover plate assembly 20 and the support assembly 10, ensure detection accuracy, and reduce the safety hazards of the cover plate device 100.

[0056] In one embodiment, such as Figure 3 and Figure 4As shown, the alignment member 31 also includes a bottom surface 312, a top surface 313, and a side surface 314. The bottom surface 312 and the top surface 313 are opposite each other in the first direction Z. The bottom surface 312 is connected to the support assembly 10 or the cover plate assembly 20. The side surface 314 is connected to the bottom surface 312. The alignment surface connects the top surface 313 and the side surface 314 at the end away from the bottom surface 312. The side surface 314 is used to contact the inner wall of the alignment groove 32.

[0057] The alignment component 31 and the support assembly 10 or the cover plate assembly 20 can be an integral structure or a separate structure. The alignment component 31 and the support assembly 10 or the cover plate assembly 20 can be connected and fixed by welding, bonding, snap-fitting, screwing, riveting, magnetic connection and other methods.

[0058] The shapes of the bottom surface 312 and the top surface 313 are not limited and can be rectangular, square, circular, trapezoidal, etc. Optionally, in the orthographic projection of the first direction Z, the top surface 313 is located inside the bottom surface 312. This arrangement facilitates the formation of an alignment surface that is inclined relative to the first direction Z to guide the alignment member 31.

[0059] Optionally, the alignment surface includes a first alignment surface 311, which is used to be opposite to the inner wall of the alignment groove 32 in the second direction X.

[0060] The angle between the side surface 314 and the first direction Z is smaller than the angle between the first parallel surface 311 and the first direction Z.

[0061] Optionally, the first alignment surface 311 has an angle with the first direction Z, the first alignment surface 311 is opposite to the inner wall of the alignment groove 32, and the first alignment surface 311 is oriented towards the support assembly 10 or the cover assembly 20. For example, the angle between the first alignment surface 311 and the first direction Z can be 10°-60°, specifically 10°, 15°, 20°, 30°, 40°, 45°, 50°, 60°, etc. When the angle between the first alignment surface 311 and the first direction Z is too small, the first alignment surface 311 cannot effectively guide the alignment member 31 into the alignment groove 32; when the angle between the first alignment surface 311 and the first direction Z is too large, the relative position between the support assembly 10 and the cover assembly 20 cannot be fixed after the alignment member 31 is inserted into the alignment groove 32, and the cover assembly 20 may still slide relative to the support assembly 10, affecting the detection.

[0062] The included angle between the first pair of opposing surfaces 311 and the first direction Z satisfies being between 10° and 60°. The opposing surfaces 311 can guide the alignment member 31 during the process of the alignment member 31 extending into the alignment slot 32, avoiding the situation that the alignment member 31 cannot extend into the alignment slot 32 due to small positional deviations at the moment of just contacting. At the same time, after the alignment member 31 extends into the alignment slot 32 to complete alignment, the side surface 314 can contact the side wall of the alignment slot 32 to fix the position between the cover plate assembly 20 and the support assembly 10, and no further offset will occur.

[0063] It can be understood that the side surface 314 of the alignment member 31 is the entire circumferential surface of the alignment member 31 in the circumferential direction, and one end of the side surface 314 is connected to the four peripheral edges of the bottom surface 312. Optionally, when the bottom surface 312 is rectangular, the side surface 314 and the bottom surface 312 together form five surfaces of a cuboid. At least a part of the end of the side surface 314 far from the bottom surface 312 is connected to the first pair of opposing surfaces 311. The part of the end of the side surface 314 far from the bottom surface 312 except the part connected to the first pair of opposing surfaces 311 can be directly connected to the top surface 313, or this part is flush with the part where the side surface 314 is connected to the first pair of opposing surfaces 311.

[0064] Optionally, the included angle between the side surface 314 and the first direction Z can be 0° - 8°, and there is no specific limitation. In a specific embodiment, the included angle between the side surface 314 and the first direction Z is 0°, that is, the side surface 314 is parallel to the first direction Z.

[0065] With such a setting, when the alignment member 31 completely extends into the alignment slot 32, at least a part of the side surface 314 contacts the inner wall of the alignment slot 32 in the second direction X, which can fix the relative position between the cover plate assembly 20 and the support assembly 10, avoiding further positional offset after the cover plate assembly 20 is placed on the support assembly 10.

[0066] In one embodiment, as Figure 3 and Figure 4 shown, the alignment slot 32 includes a first side wall 321, a second side wall 322 and a third side wall 323. The second side wall 322 and the third side wall 323 are opposite in the third direction Y. The first side wall 321 connects the second side wall 322 and the third side wall 323. The first pair of opposing surfaces 311 is used for relative sliding with the first side wall 321.

[0067] Optionally, the first side wall 321, the second side wall 322 and the third side wall 323 together form the inner wall of the alignment slot 32. The first side wall 321 is perpendicular to both the second side wall 322 and the third side wall 323. In the orthographic projection in the first direction Z, the inner wall of the alignment slot 32 can be approximately in the shape of a "匚". Optionally, the first side wall 321 is opposite to the opening of the alignment slot 32.

[0068] This configuration provides a larger alignment space for the alignment member 31, thereby increasing the maximum permissible error between the cover plate assembly 20 and the support assembly 10.

[0069] Optionally, when the alignment member 31 is fully inserted into the alignment groove 32, the side 314 contacts the first side wall 321, the second side wall 322 and the third side wall 323, or the side 314 contacts any two of the first side wall 321, the second side wall 322 and the third side wall 323, which can fix the relative position between the cover plate assembly 20 and the support assembly 10 and prevent positional shift after the cover plate assembly 20 is placed on the support assembly 10.

[0070] In one embodiment, such as Figure 3 and Figure 4 As shown, the alignment member 31 also includes a second alignment surface 315 and a third alignment surface 316 that are opposite to each other in the third direction Y. The first alignment surface 311 connects the second alignment surface 315 and the third alignment surface 316. When the cover assembly 20 moves toward the support assembly 10 and has an offset relative to the support assembly 10 in the third direction Y, the second alignment surface 315 is used to slide relative to the second sidewall 322, or the third alignment surface 316 is used to slide relative to the third sidewall 323, so that the support assembly 10 and the cover assembly 20 are aligned in the third direction Y.

[0071] Optionally, both the second alignment surface 315 and the third alignment surface 316 connect the top surface 313 and the side surface 314. Optionally, the second alignment surface 315 forms an angle with the first direction Z, the second alignment surface 315 is opposite to the second side wall 322, and the second alignment surface 315 is disposed towards the support assembly 10 or the cover assembly 20; the third alignment surface 316 forms an angle with the first direction Z, the third alignment surface 316 is opposite to the third side wall 323, and the third alignment surface 316 is disposed towards the support assembly 10 or the cover assembly 20. The angle between the second alignment surface 315 and the third alignment surface 316 and the first direction Z can be referenced to the angle between the first alignment surface 311 and the first direction Z, and will not be repeated here.

[0072] When the cover plate assembly 20 moves toward the support assembly 10 until the alignment member 31 just contacts the support assembly 10, there may be a certain positional offset between the two in the third direction Y. At this time, as the cover plate assembly 20 continues to move toward the support assembly 10, if the cover plate assembly 20 shifts relative to the support assembly 10 toward the second sidewall 322, the second alignment surface 315 can contact and slide relative to the second sidewall 322; if the cover plate assembly 20 shifts relative to the support assembly 10 toward the third sidewall 323, the third alignment surface 316 can contact and slide relative to the third sidewall 323.

[0073] The alignment member 31 is guided to slide into the alignment groove 32 via the second alignment surface 315 or the third alignment surface 316 and the inner wall of the alignment groove 32, thereby achieving alignment of the support assembly 10 and the cover plate assembly 20 in the third direction Y. This configuration increases the maximum permissible error between the cover plate assembly 20 and the support assembly 10, avoids the cover plate assembly 20 tilting due to the alignment member 31 failing to extend into the alignment groove 32, achieves alignment between the cover plate assembly 20 and the support assembly 10, ensures detection accuracy, and reduces safety hazards of the cover plate device 100.

[0074] By setting the first alignment surface 311, the second alignment surface 315, and the third alignment surface 316, the cover plate assembly 20 and the support assembly 10 can be aligned in the second direction X and the third direction Y, which can improve the stability and service life of the equipment.

[0075] In one embodiment, there are multiple alignment members 31 and multiple alignment grooves 32. The support assembly 10 or the cover plate assembly 20 is provided with at least one alignment member 31 on each of the opposite sides in the second direction X, and the multiple alignment members 31 and multiple alignment grooves 32 correspond one-to-one.

[0076] Optional, such as Figure 1 and Figure 2 As shown, there are two alignment members 31 and two alignment grooves 32. The support assembly 10 or the cover plate assembly 20 is provided with one alignment member 31 on each of the opposite sides in the second direction X, and the openings of the two alignment grooves 32 are opposite to each other in the second direction X.

[0077] Optionally, the two alignment members 31 are directly opposite each other in the second direction X, and the two alignment grooves 32 are also directly opposite each other in the second direction X. With this setting, the positions of the alignment members 31 on both sides are more reasonable, which can ensure the connection stability between the cover plate assembly 20 and the support assembly 10.

[0078] In one embodiment, there are four alignment members 31, with the support assembly 10 or the cover plate assembly 20 having alignment members 31 on opposite sides in the second direction X and the third direction Y; or, in another embodiment, there are four alignment members 31, with the support assembly 10 or the cover plate assembly 20 having two alignment members 31 on opposite sides in the second direction X, and the two alignment members 31 being spaced apart in the third direction Y. Any of the above methods are acceptable and there is no specific limitation.

[0079] By providing at least one alignment member 31 and an alignment groove 32 on opposite sides of the support assembly 10 or the cover assembly 20 in the second direction X, while ensuring that the alignment member 31 can extend into the alignment groove 32 to achieve alignment of the cover assembly 20 and the support assembly 10 in the second direction X, the alignment member 31 and the alignment groove 32 on both sides can further restrict the relative position of the cover assembly 20 and the support assembly 10, and can prevent the cover assembly 20 from shifting relative to the support assembly 10 towards the side in the second direction X.

[0080] In one embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, the support assembly 10 also includes a first transparent plate 11 and a first mounting frame 12, with the first mounting frame 12 fitted around the first transparent plate 11. The cover plate assembly 20 also includes a second transparent plate 21 and a second mounting frame 22, with the second mounting frame 22 fitted around the second transparent plate 21. The alignment member 31 is engaged with the alignment groove 32 to align the second transparent plate 21 with the first transparent plate 11 in the second direction X.

[0081] Both the first transparent plate 11 and the second transparent plate 21 can be approximately rectangular, and their areas can be the same or different, without limitation. The materials of the first transparent plate 11 and the second transparent plate 21 can be glass, acrylic (PMMA), polycarbonate (PC), polystyrene (PS), polyethylene terephthalate (PET), cyclic olefin polymer (COP), and cyclic olefin copolymer (COC), etc., without specific limitations.

[0082] The first mounting frame 12 and the second mounting frame 22 can be made of materials with high structural strength, specifically metals, high-strength plastics, ceramics, etc. Metals include aluminum, aluminum alloys, magnesium alloys, iron, and iron alloys. The first mounting frame 12 or the second mounting frame 22 can be a one-piece structure, and the one-piece molding process can be stamping, casting, etc., without limitation. The first mounting frame 12 or the second mounting frame 22 can also be a separate structure, with the various frames of the first mounting frame 12 connected and fixed by welding, bonding, snap-fitting, screwing, etc.

[0083] Optionally, the second mounting frame 22 and / or the first mounting frame 12 may also be provided with a clearance groove for accommodating at least a portion of the detection device.

[0084] In one specific embodiment, such as Figures 1 to 4 As shown, the first mounting frame 12 has an alignment groove 32, and the second mounting frame 22 is connected to an alignment member 31. Figure 1 and Figure 3 The image shows the alignment member 31 extending into the alignment groove 32.

[0085] The first transparent panel 11 and the first mounting frame 12 can be connected and fixed by means of adhesive, snap-fit, screw, riveting, etc., without limitation. The connection method between the second transparent panel 21 and the second mounting frame 22 is similar to that between the first transparent panel 11 and the first mounting frame 12, and can be referred to accordingly.

[0086] With this configuration, when the cover plate assembly 20 is placed on the support assembly 10, the first mounting frame 12 and the second mounting frame 22 are aligned and connected in the second direction X, so that the first transparent plate 11 and the second transparent plate 21 are aligned. The part to be tested is placed between the first transparent plate 11 and the second transparent plate 21. The first mounting frame 12 can provide support for the second mounting frame 22. The testing device can test the part to be tested through the transparent first transparent plate 11 and the second transparent plate 21.

[0087] In one embodiment, such as Figure 3 As shown, the first mounting frame 12 has an alignment groove 32, the opening of which is located on the side peripheral surface of the first mounting frame 12, and the alignment member 31 is connected to the second mounting frame 22. Alternatively, in another embodiment, the second mounting frame 22 has an alignment groove 32, the opening of which is located on the side peripheral surface of the second mounting frame 22, and the alignment member 31 is connected to the first mounting frame 12.

[0088] Optionally, the alignment member 31 is connected to the surface of the first mounting frame 12 facing the first mounting frame 12. Alternatively, the alignment member 31 may also be connected to at least a portion of the side surface 314 of the first mounting frame 12, provided that the alignment member 31 protrudes from the surface of the first mounting frame 12 facing the first mounting frame 12; there are no restrictions. Alternatively, the alignment member 31 may protrude from the surface of the second mounting frame 22 facing the first mounting frame 12, and the connection position can refer to the above description.

[0089] The opening of the alignment groove 32 is located on the outer peripheral surface of the first mounting frame 12 or the second mounting frame 22, which can improve the maximum permissible installation error between the first mounting frame 12 and the second mounting frame 22. When the cover plate assembly 20 and the support assembly 10 are offset in the second direction X, the alignment member 31 can extend into the alignment groove 32 under the guidance of the first alignment surface 311 and the alignment groove 32, so as to prevent the cover plate assembly 20 from tilting.

[0090] In one embodiment, such as Figures 5 to 7 As shown, the cover plate device 100 also includes a lifting assembly 40, which is used to move in the first direction Z and be placed on the lifting assembly 40. The lifting assembly 40 can be connected and fixed to the support assembly 10, or it can be spaced apart from the support assembly 10, and there is no specific limitation.

[0091] The lifting assembly 40 is used to drive the cover plate assembly 20 to move toward or away from the support assembly 10 in the first direction Z. Specifically, before testing, the cover plate assembly 20 is placed on the lifting assembly 40, so that the lifting assembly 40 can move the cover plate assembly 20 toward or away from the support assembly 10. During the process of placing the cover plate assembly 20 on the lifting assembly 40, the cover plate assembly 20 may shift relative to the lifting assembly 40. This may further cause the cover plate assembly 20 and the support assembly 10 to shift their positions when the lifting assembly 40 moves the cover plate assembly 20 to the support assembly 10. Therefore, the two need to be aligned and connected.

[0092] One of the lifting assembly 40 and the cover assembly 20 has a guide 33 and the other has a guide groove 34. The guide 33 is for extending into the guide groove 34. The guide 33 has a guide surface, which is used to slide relative to the inner wall of the guide groove 34 when the cover assembly 20 moves toward the lifting assembly 40 and is offset relative to the lifting assembly 40 in the second direction X, so as to align the lifting assembly 40 and the cover assembly 20 in the second direction X.

[0093] The guide component 33 can be an integral structure with the lifting assembly 40 or the cover plate assembly 20, or it can be a separate structure. The alignment component 31 can be connected and fixed with the lifting assembly 40 or the cover plate assembly 20 by welding, bonding, snap-fitting, screwing, riveting, magnetic connection, etc.

[0094] Optionally, the guide surface includes a first guide surface 331, which is used to slide relative to the inner wall of the guide groove 34 to align the lifting assembly 40 and the cover plate assembly 20 in the second direction X.

[0095] Optionally, the guide member 33 further includes a second guide surface 332 and a third guide surface (not shown) that are opposite to each other in the third direction Y. The first guide surface 331 connects the second guide surface 332 and the third guide surface. When the cover plate assembly 20 moves toward the lifting assembly 40 and has an offset relative to the lifting assembly 40 in the third direction Y, the second guide surface 332 or the third guide surface is used to slide relative to the inner wall of the guide groove 34 so that the cover plate assembly 20 and the lifting assembly 40 are aligned in the third direction Y.

[0096] The specific structure of the guide member 33 is similar to that of the alignment member 31, and can be referred to the above without further details.

[0097] By setting up a lifting assembly 40, one of the lifting assembly 40 and the cover plate assembly 20 has a guide member 33 and the other has a guide groove 34. When the cover plate assembly 20 moves toward the lifting assembly 40, and the two are offset in the second direction X, the guide surface of the guide member 33 can slide relative to the inner wall of the guide groove 34 to guide the guide member 33. This can correct the initial positional deviation in time and prevent the guide member 33 from being unable to extend into the guide groove 34, which would cause the cover plate assembly 20 to tilt relative to the lifting assembly 40. This can reduce the safety hazards of the cover plate device 100.

[0098] In one embodiment, the lifting assembly 40 includes a lifting drive mechanism 41 and a mounting platform 42, wherein the lifting drive mechanism 41 is used to drive the mounting platform 42 to move along a first direction Z.

[0099] Optional, such as Figure 7 As shown, the lifting assembly 40 also includes a base 43, and the lifting drive mechanism 41 includes a lifting drive component 411 and a lifting transmission component (not shown). The lifting drive component 411 is disposed on the base 43, and the lifting transmission component is connected to the mounting platform 42. The lifting transmission component and the lifting drive component 411 are in a transmission cooperation so that the lifting drive component 411 drives the mounting platform 42 to move.

[0100] The lifting drive component 411 can be a motor, hydraulic cylinder, pneumatic cylinder, etc., without limitation. The lifting drive component 411 can be used to drive the lifting transmission component to move along its own axial direction. The lifting drive component 411 has a drive shaft, which can move linearly during operation. For example, when the lifting drive component 411 is a motor, the motor can be a linear motor or a lead screw motor, enabling its drive shaft to move linearly; or, for example, when the lifting drive component 411 is a hydraulic cylinder or pneumatic cylinder, the drive shaft is a piston rod, enabling linear extension and retraction. Alternatively, the lifting drive component 411 can also be used to drive the lifting transmission component to rotate around its own axis, without limitation.

[0101] Optional, such as Figure 7 As shown, the lifting assembly 40 also includes a guide shaft 44, which extends along the first direction Z and one end of the guide shaft 44 is connected to the base 43. The mounting platform 42 is slidably connected to the guide shaft 44, and the lifting drive mechanism 41 is used to drive the mounting platform 42 to slide relative to the guide shaft 44 along the first direction Z.

[0102] There can be one or more guide shafts 44; there is no limitation. In one specific embodiment, such as... Figure 2 As shown, there are two guide shafts 44 spaced apart, located at opposite ends of the mounting platform 42, which can stably support the mounting platform 42.

[0103] Optionally, the mounting platform 42 is fitted onto the guide shaft 44 and can be slidably connected via a linear bearing 45.

[0104] One of the mounting platform 42 and the second mounting frame 22 is connected to a guide member 33, and the other has a guide groove 34. The guide member 33 and the guide groove 34 are connected to each other so that the second mounting frame 22 and the mounting platform 42 are aligned in the second direction X.

[0105] Optionally, the guide member 33 and the mounting platform 42 or the second mounting frame 22 can be an integral structure or a separate structure, without limitation. Optionally, the second mounting frame 22 has a guide groove 34, the opening of which is located on the side of the second mounting frame 22; or, the mounting platform 42 has a guide groove 34, the opening of which is located on the side 314 of the mounting platform 42.

[0106] By setting up a lifting drive mechanism 41 and a mounting platform 42, the lifting drive mechanism 41 drives the mounting platform 42 to move in the first direction Z, thereby causing the cover plate assembly 20 to move toward or away from the support assembly 10. The mounting platform 42 and the cover plate assembly 20 are aligned in the second direction X through the guide member 33 and the guide groove 34 to avoid the position of the two from deviating, which would further cause the position of the cover plate assembly 20 to shift from that of the support assembly 10 when it moves to the support assembly 10.

[0107] In one embodiment, there are multiple guide members 33 and multiple guide grooves 34. The lifting assembly 40 or the cover plate assembly 20 is provided with at least one guide member 33 on each of the opposite sides, and the multiple guide members 33 and multiple guide grooves 34 correspond one-to-one.

[0108] Optional, such as Figure 5 and Figure 6 As shown, the second mounting frame 22 has a guide groove 34, the opening of which is located on the side of the second mounting frame 22. Alternatively, the mounting platform 42 has a guide groove 34, the opening of which is located on the side 314 of the mounting platform 42. This arrangement can improve the maximum permissible installation error between the second mounting frame 22 and the mounting platform 42.

[0109] Optionally, the guide member 33 is connected to the surface of the second mounting frame 22 facing the mounting platform 42. Alternatively, the guide member 33 may also be connected to at least a portion of the side 314 of the second mounting frame 22, provided that the guide member 33 protrudes from the surface of the second mounting frame 22 facing the mounting platform 42; there are no restrictions. Alternatively, the guide member 33 may protrude from the surface of the mounting platform 42 facing the second mounting frame 22, and the connection position can refer to the above description.

[0110] Optionally, there are two guide members 33 and two guide grooves 34. The lifting assembly 40 or the cover plate assembly 20 is provided with one guide member 33 on each of the opposite sides in the second direction X, and the openings of the two guide grooves 34 are opposite to each other in the second direction X.

[0111] Alternatively, there may be four or six guide members 33 and guide grooves 34, etc. The specific settings can be referred to the aforementioned alignment member 31 and alignment groove 32, and will not be repeated here.

[0112] By setting at least one guide member 33 and a guide groove 34 on each of the opposite sides of the lifting assembly 40 or the cover assembly 20, the guide member 33 can be inserted into the guide groove 34 to achieve alignment of the cover assembly 20 and the lifting assembly 40 in the second direction X. At the same time, the guide member 33 and the guide groove 34 on both sides can further restrict the relative position of the cover assembly 20 and the lifting assembly 40, and can prevent the cover assembly 20 from shifting relative to the lifting assembly 40 towards the side in the second direction X.

[0113] In one embodiment, such as Figure 1 and Figure 5 As shown, the alignment member 31 and the guide member 33 are located on the same side of the cover plate device 100.

[0114] Optionally, the second mounting frame 22 includes a body 221 and an extension 222. The extension 222 is connected to one side of the body 221 in the second direction X and protrudes from the outer peripheral surface of the body 221. The body 221 is connected to an alignment member 31 or has an alignment groove 32, and the extension 222 is connected to a guide member 33 or a specific guide groove 34. With this configuration, when the alignment member 31 and the guide member 33 are located on the same side of the cover plate device 100, interference between the alignment member 31 and the guide member 33 can be avoided.

[0115] Alternatively, alignment members 31 and guide members 33 may be provided on adjacent sides of the cover plate assembly 100. Optionally, alignment members 31 may be provided on opposite sides of the cover plate assembly 100 in the second direction X, and guide members 33 may be provided on opposite sides of the cover plate assembly 100 in the third direction Y. Understandably, the structure of the guide members 33 may be adaptively adjusted in this case, and the guide surface of the guide members 33 may be used to slide relative to the guide groove 34 to align the lifting assembly 40 and the cover plate assembly 20 in the second direction X.

[0116] With this configuration, the alignment member 31 and the guide member 33 can be adjusted according to the specific usage needs of the cover plate device 100, which can adapt to the needs of different scenarios and has high flexibility of use.
