DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Therefore, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, so that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. On the contrary, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0024] Electrical equipment all require connectors to connect cables to the host. In order to ensure the shielding of the cables, a sealing cover is usually set to cover the connector. At the same time, in order to facilitate the bending of the cables, a wire through hole is opened on the side wall of the sealing cover, and the inner wall of the through hole is sprayed with a coating for electromagnetic shielding. For this, the coating strength needs to be tested. The existing coating detection usually adopts the scratch method, which controls the movement of the polishing piece to apply friction. In order to accurately control the position of the scratch, the existing method will accurately control the moving distance of the polishing piece, that is, control the stroke of the polishing piece to be the same as the length of the through hole, so as to accurately polish the coating on the inner wall of the through hole. For example, when polishing the through hole on the straight plate, the moving stroke of the polishing piece is controlled to be consistent with the thickness of the straight plate, so as to avoid damage to the outer edge of the through hole after the polishing piece moves out of the through hole. However, the inventor found that because the side wall of the circular sealing cover is an arc surface, if the polishing piece is also controlled not to move out of the through hole, there will be a polishing blank area. And according to the size requirements of the scratch knife in the scratch test: for thinner coatings (such as 0.2-0.5μm), a scratch knife with a diameter of 2mm or larger is usually used for testing, and for thicker coatings (such as above 3μm), a scratch knife with a diameter of 1mm or smaller can be used to ensure that the pressure applied by the scratch knife on the coating can meet the requirements of the coating strength test. At this time, if the through hole is fully polished, it is inevitable that part of the scratch knife will extend out of the hole, and the extended scratch knife will scratch the outer wall of the sealing cover.

[0025] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0027] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] like Figure 1As shown, at least one disclosed embodiment provides a circular CNC metal part side wall hole coating detection device, comprising: a scratching device 1 and a detection device 2; the scratching device 1 is suitable for applying friction on the inner wall of the side wall hole 53 of the metal part 5; the detection device 2 is suitable for detecting whether there are scratches on the inner wall of the side wall hole 53 of the metal part 5 after friction, and if there are scratches, it is judged that the coating strength of the inner wall of the side wall hole 53 of the metal part 5 is unqualified; wherein the scratching device 1 comprises: a moving mechanism 11 and a plurality of scratching mechanisms 12; the scratching mechanism 12 is circumferentially equidistantly arranged on the outer wall of the moving mechanism 11, the scratching mechanism 12 extends out of the moving mechanism 11, and the scratching mechanism 12 is slidably connected to the moving mechanism 11; the moving mechanism 11 is suitable for driving the scratching mechanism 12 to contact the inner wall of the side wall hole 53 of the metal part 5, and driving the scratching mechanism 12 to move along the axial direction of the side wall hole 53 of the metal part 5 to apply friction (the specific moving direction of the scratching mechanism 12 is as shown in FIG. 1 ). Figure 2 As shown in FIG. 5(F), after the cutting mechanism 12 is completely moved out of the side wall hole 53 of the metal part 5, the length of the cutting mechanism 12 extending out of the moving mechanism 11 is reduced, thereby achieving that the cutting mechanism 12 will automatically retract after the scratching is completed, thereby avoiding the cutting mechanism 12 from causing damage to the outer edge of the side wall hole 53 of the metal part 5.

[0029] In this embodiment, the bottom plate 51 of the metal member 5 is circular, and a ring body 52 is disposed on the bottom plate 51 . A side wall hole 53 is opened on the ring body 52 , and the axial direction of the side wall hole 53 is parallel to a diameter of the bottom plate 51 .

[0030] like Figure 7 As shown, in an optional embodiment, the cutting mechanism 12 includes: a cutting blade 121; a first groove 122 is provided on the top surface of the cutting blade 121, and a second groove 123 is provided on the bottom surface of the cutting blade 121; the first groove 122 is connected with the second groove 123; a pair of side walls of the cutting blade 121 are provided with a slide groove 124; the slide groove 124 is vertically arranged, and the slide groove 124 is connected with the second groove 123, and the slide groove 124 is open on one side close to the axis of the outer sleeve 111.

[0031] In this embodiment, the scratching blade 121 contacts the inner wall of the side wall hole 53 to apply friction. If the coating strength inside the side wall hole 53 is not up to standard, scratches will be formed after friction.

[0032] In this embodiment, through the connection between the first groove 122 and the second groove 123, a connected flow channel is formed in the cutting blade 121, which facilitates the subsequent flow of gas.

[0033] like Figure 2 and Figure 3As shown, in an optional embodiment, the moving mechanism 11 includes: an outer sleeve 111; the length direction of the outer sleeve 111 is parallel to the axial direction of the side wall hole 53 of the metal part 5; a plurality of strip holes 112 are circumferentially equidistantly opened on the outer wall of the outer sleeve 111, and the strip holes 112 correspond to the cutting blades 121, and the cutting blades 121 pass through the corresponding strip holes 112, and the outer wall of the cutting blades 121 contacts the inner wall of the strip holes 112; when the first groove 122 is completely exposed to the side wall hole 53 of the metal part 5, part of the airflow in the outer sleeve 111 flows out from the first groove 122, and the thrust of the airflow on the cutting blade 121 is reduced, and at this time, the corresponding cutting blade 121 moves toward the axial direction of the outer sleeve 111 to reduce the length of the cutting blade 121 extending out of the outer sleeve 111.

[0034] In this embodiment, the outer wall of the cutting blade 121 contacts the inner wall of the strip hole 112 , so that the airflow in the outer sleeve 111 cannot flow out from between the outer wall of the cutting blade 121 and the inner wall of the strip hole 112 .

[0035] In this embodiment, as the outer sleeve 111 moves, the first groove 122 that was originally completely blocked by the side wall hole 53 will gradually be exposed. When the first groove 122 of the cutting blade 121 is completely exposed from the side wall hole 53, the force applied by the gas in the outer sleeve 111 to the cutting blade 121 cannot keep the cutting blade 121 extending out of the strip hole 112. The cutting blade 121 will retract into the outer sleeve 111, that is, the length of the cutting blade 121 extending out of the strip hole 112 is reduced, and the cutting blade 121 will not contact the outer edge of the side wall hole 53, and will not cause damage to the outer edge of the side wall hole 53.

[0036] like Figure 4 As shown, in an optional embodiment, the moving mechanism 11 also includes: an inner sleeve 113 inserted into the outer sleeve 111; a pair of side walls of the cutting blade 121 are each provided with a slide groove 124; the slide groove 124 is vertically arranged, and the slide groove 124 is connected to the second groove 123; a limiting rod 114 is arranged in the strip hole 112, and the limiting rod 114 is located in the corresponding slide groove 124; a chamfer 125 is arranged on the side of the cutting blade 121 close to the axis of the outer sleeve 111, and the chamfer 125 is close to the end face of the inner sleeve 113; a spring 115 is arranged between the limiting rod 114 and the inner top surface of the second groove 123; when the outer sleeve 111 drives the cutting blade 121 to move, the inner sleeve 113 contacts the chamfer 125 to push the cutting blade 121 out of the side wall of the outer sleeve 111.

[0037] In this embodiment, the limiting rod 114 can support the cutting blade 121 and guide the cutting blade 121 when the cutting blade 121 moves.

[0038] In this embodiment, the pulling force exerted by the spring 115 in the initial state causes only a very short length of the cutting blade 121 to protrude from the outer sleeve 111. At this time, when the cutting blade 121 extends into the side wall hole 53, the cutting blade 121 does not contact the inner wall of the side wall hole 53.

[0039] In this embodiment, the cutting blade 121 can be pushed out of the outer sleeve 111 by the movement of the inner sleeve 113, and the inner sleeve 113 can slide within the outer sleeve 111.

[0040] In this embodiment, the spring 115 can be used to reset the cutting blade 121.

[0041] In this embodiment, the scratching device 1 further includes: a second moving pair 14; a fixed sleeve 141 is provided on the second moving pair 14; a part of the outer sleeve 111 extends into the fixed sleeve 141, and the outer sleeve 111 is slidably connected to the fixed sleeve 141; the other end of the fixed sleeve 141 is sealed; one end of the inner sleeve 113 is connected to the sealed end face of the fixed sleeve 141; an air source interface 142 can be provided on the fixed sleeve 141, the air source interface 142 is in communication with the inside of the outer sleeve 111, an air source is connected through the air source interface 142, and the gas inside the outer sleeve 111 is pumped out or air is introduced into the outer sleeve 111 through the air source; the second moving pair 14 can drive the fixed sleeve 141 to move so as to move the moving mechanism 11 and the cutting tool mechanism 12.

[0042] In this embodiment, the second moving pair 14 can be a three-axis moving pair to facilitate better driving of the fixed sleeve 141 to move.

[0043] In this embodiment, when it is necessary to scratch the side wall hole 53, the metal part 5 is first limited by the limit block 13, and then the second moving pair 14 drives the scratching mechanism 12 to extend into the side wall hole 53, and the gas in the outer sleeve 111 is extracted through the gas source. The flow rate of the extracted gas is greater than the flow rate of the gas entering the outer sleeve 111 through all the first grooves 122 and the second grooves 123, so that the gas pressure in the outer sleeve 111 decreases, and the length of the outer sleeve 111 extending into the fixed sleeve 141 increases. At this time Since the inner sleeve 113 is fixed and does not move, the outer sleeve 111 moves with the blade 121 to move synchronously, so that the blade 121 is close to the inner sleeve 113, and the inner sleeve 113 contacts the guide angle 125 of the blade 121 to push the blade 121 away from the axis of the outer sleeve 111, so that the length of the blade 121 extending out of the outer sleeve 111 increases, and the blade 121 contacts the inner wall of the side wall hole 53. At this time, the first groove 122 is in a state of being completely blocked by the side wall hole 53, and the blade 121 is The end of the blade 121 close to the fixed sleeve 141 is located outside the side wall hole 53, and the end of the blade 121 away from the fixed sleeve 141 is located inside the side wall hole 53, so that the blade 121 can completely rub along the axial direction of the side wall hole 53. At this time, the air is pumped out and the air is ventilated into the outer sleeve 111. Since the first groove 122 is blocked, the air pressure in the outer sleeve 111 gradually increases, and the air pressure will push the outer sleeve 111 away from the fixed sleeve 141, completing the friction with the side wall hole 53, and the air pressure can be used to maintain The scratching blade 121 is held in contact with the inner wall of the side wall hole 53 until the first groove 122 is completely exposed from the side wall hole 53. The air pressure inside the outer sleeve 111 is less than the pulling force applied by the spring 115 to the scratching blade 121. At this time, the scratching blade 121 will shrink into the outer sleeve 111 to prevent the scratching blade 121 from continuing to extend out of the outer sleeve 111 due to the pressure inside the outer sleeve 111 after the scratching blade 121 is completely exposed from the side wall hole 53, thereby preventing the scratching blade 121 from damaging the side wall of the metal part 5.

[0044] like Figure 5 As shown, a corner on the bottom surface of the scoring blade 121 close to the inner sleeve 113 is a guide angle 125. When the gas source extracts the gas in the outer sleeve 111 to move the outer sleeve 111, the outer sleeve 111 drives the scoring blade 121 to move toward the fixed inner sleeve 113, and the guide angle 125 on the bottom surface of the scoring blade 121 approaches and contacts the end surface of the inner sleeve 113. The inner sleeve 113 pushes the scoring blade 121 out of the outer sleeve 111 through the guide angle 125 on the bottom surface of the scoring blade 121, that is, the length of the scoring blade 121 extending out of the outer sleeve 111 increases.

[0045] In this embodiment, the outer wall of the scribing blade 121 contacts the inner wall of the strip-shaped hole 112 to reduce the gas from flowing out from between the scribing blade 121 and the strip-shaped hole 112 or flowing into the outer sleeve 111 .

[0046] like Figure 6As shown, a limiting rod 114 is provided in the strip hole 112, and the length direction of the limiting rod 114 can be parallel to the length direction of the strip hole 112. The limiting rod 114 passes through two slide grooves 124 of a cutting blade 121. The two ends of the limiting rod 114 extend out of the slide groove 124 and are connected to the inner wall of the strip hole 112, so that the cutting blade 121 can be mounted on the corresponding limiting rod 114 to prevent the cutting blade 121 from falling into the outer sleeve 111.

[0047] Specifically, Figures 8 to 10 As shown, when the cutting blade 121 slides in the side wall hole 53, if the coating strength of the inner wall of the side wall hole 53 is insufficient, the following may occur: Fig. 9 The engraving situation shown at B in the figure shows that there is a scratch, and as Fig.10 As shown, when the cutting blade 121 in the related art is cutting, the curved outer wall of the metal part 5 will be scratched as shown in A due to the upward thrust on the cutting blade 121. Therefore, it is necessary to reduce the length of the cutting mechanism 12 extending out of the moving mechanism 11 after the cutting mechanism 12 is completely moved out of the side wall hole 53 of the metal part 5 to prevent the curved outer wall of the metal part 5 from being scratched.

[0048] In an optional embodiment, one end face of the outer sleeve 111 is sealed, and the open end of the outer sleeve 111 is connected to an air source, for example, through a hose, and the air source is electrically connected to a control module, and the control module controls the air source to ventilate the outer sleeve 111, and pushes the outer sleeve 111 to move by the airflow; when the first groove 122 is completely covered by the side wall hole 53 of the metal part 5, the airflow in the outer sleeve 111 pushes the cutting blade 121 to closely contact the inner wall of the side wall hole 53 of the metal part 5, and at this time, the airflow pushes the outer sleeve 111 to move along the axial direction of the side wall hole 53 of the metal part 5, so that the cutting blade 121 applies friction to the inner wall of the side wall hole 53 of the metal part 5.

[0049] In this embodiment, the size of the second groove 123 is larger than that of the first groove 122. When airflow is introduced into the outer sleeve 111, the airflow can better push the second groove 123 closer to one side of the first groove 122, so that the cutting blade 121 can be better resisted by the airflow to contact the inner wall of the side wall hole 53 of the metal part 5.

[0050] like Figure 1 As shown, in an optional embodiment, the scratching device 1 also includes: a limit block 13; the limit block 13 is provided with an arc groove 131 adapted to the outer wall of the metal part 5, the arc groove 131 is suitable for limiting the metal part 5, the limit block 13 is provided with a through hole 132 corresponding to the side wall hole 53 of the metal part 5, and the outer sleeve 111 passes through the through hole 132 and extends into the side wall hole 53 of the metal part 5.

[0051] In this embodiment, the limiting block 13 can better limit the metal component 5 through the arc groove 131 to prevent the metal component 5 from moving when rubbing against the side wall hole 53 of the metal component 5 .

[0052] In this embodiment, the metal member 5 can be placed in the arc groove 131 manually, and the arc groove 131 and the metal member 5 can be tightly connected to prevent the metal member 5 from moving when the scratching blade 121 rubs the side wall hole 53.

[0053] like Figure 1 As shown, in an optional embodiment, the detection device 2 includes: a camera 21 and a rotating mechanism 22 electrically connected to the control module; the camera 21 is arranged above the rotating mechanism 22; the control module is suitable for controlling the rotating mechanism 22 to drive the metal part 5 to rotate, so that the side wall hole 53 of the metal part 5 rotates to the bottom of the camera 21; the control module is suitable for controlling the camera 21 to take a photo of the side wall hole 53 of the metal part 5 to determine whether there is a scratch in the side wall hole 53.

[0054] In this embodiment, a suction mechanism can be provided on the rotating mechanism 22 to hold the metal part 5 by suction so as to prevent the metal part 5 from falling when the metal part 5 is driven to rotate; the rotating mechanism 22 can rotate the side wall hole 53 of the metal part 5 to an upward direction. At this time, the image of the side wall hole 53 is captured by the camera 21, and the control module determines whether there is a scratch in the side wall hole 53 in the image. If there is a scratch, the control module determines that the coating in the side wall hole 53 of the metal part 5 is unqualified, otherwise, the coating is judged to be qualified.

[0055] In this embodiment, after the scratching device 1 rubs the inner wall of the side wall hole 53 of the metal part 5, the metal part 5 can be placed on the turntable 4 manually or by other means.

[0056] In this embodiment, the rotating mechanism 22 rotates the metal part 5 so that the side wall hole 53 faces upward, which can facilitate the camera 21 to better and more completely capture the image of the inner wall of the side wall hole 53, and facilitate the subsequent accurate judgment of whether there is a scratch in the side wall hole 53.

The camera 21 can be set on a lifting mechanism to drive the camera 21 to rise and fall through the lifting mechanism to facilitate the camera to extend into the side wall hole 53.

[0058] In this embodiment, the control module may, but is not limited to, use an image recognition method to determine whether there is a scratch in the side wall hole 53 of the metal component 5 .

[0060] In this embodiment, the second movable pair 14 may be a three-axis movable pair, so as to facilitate better loading of the metal part 5 .

[0061] In this embodiment, the suction cup 33 can suck the metal part 5 by suction, for example, the suction cup 33 sucks the bottom plate 51 of the metal part 5, so as to firmly suck the suction cup 33 and prevent the metal part 5 from falling during the process of carrying and loading the metal part 5.

[0062] In an optional embodiment, a turntable 4 is provided on the other side of the first movable pair 32; the control module controls the first movable pair 32 to drive the suction cup 33 to move above the turntable, and then the control module controls the suction cup 33 to place the sucked metal part 5 on the turntable; the turntable 4 is electrically connected to the control module, and the control module controls the turntable 4 to rotate so that the metal part 5 on the turntable 4 passes through the scratch device 1 and the detection device 2 in sequence.

[0063] In this embodiment, the metal component 5 can be moved between various workstations via the turntable 4, so that the metal component 5 can pass through all the working steps.

[0064] At least one other publicly disclosed embodiment also provides a detection method using the above-mentioned circular CNC metal part side wall hole coating detection device, including: the moving mechanism 11 drives the cutting tool mechanism 12 to contact the inner wall of the side wall hole 53 of the metal part 5, and drives the cutting tool mechanism 12 to move axially along the side wall hole 53 of the metal part 5 to apply friction, and the length of the cutting tool mechanism 12 extending out of the moving mechanism 11 decreases after the cutting tool mechanism 12 completely moves out of the side wall hole 53 of the metal part 5; the detection device 2 detects whether there are scratches on the inner wall of the side wall hole 53 of the metal part 5, and if there are scratches, it is determined that the coating strength of the inner wall of the side wall hole 53 of the metal part 5 is unqualified.
