Description

Technical Field

[0001] The present disclosure relates to a workpiece detection system, belonging to the technical field of automation equipment. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] During the automobile production process, a large number of door hinges need to be installed on the automobile body. The quality of the door hinges has a great impact on the quality of the automobile.

[0004] Door hinges are the key components that securely connect the vehicle body to the door and are the door's primary load-bearing component. The door rotates about the hinge axis to open and close. Therefore, the precision of the door hinge significantly impacts the assembly tolerances of the door on the vehicle body. These assembly tolerances significantly impact the overall vehicle's exterior quality. For example, excessive assembly tolerances can result in uneven gaps between the door and the body, leading to user distrust in the vehicle's overall quality. Consequently, door hinges are subject to high precision requirements during both production and assembly.

[0005] Generally speaking, a door hinge consists of three parts: the door assembly, the body assembly, and the hinge shaft. Bushings may be installed in the pin holes of either the door assembly or the body assembly, allowing for rotation around the hinge shaft. When the door hinge is mounted to the vehicle body, the connection is achieved through the mounting holes in the body assembly. Therefore, the location of the mounting holes significantly influences the accuracy of the door assembly, as does the contour of the mounting surface of the body assembly.

[0006] Moreover, the machining errors and assembly errors of the door hinge parts will affect the position of the mounting holes and the contour accuracy of the mounting surface. This requires the position and contour accuracy of the mounting holes to be detected after the door hinge is assembled.

[0007] However, there is no equipment in the prior art for detecting the position of the mounting hole and the contour of the mounting surface. Therefore, it is necessary to design a workpiece detection system to detect the position of the mounting hole and the contour of the mounting surface of the workpiece. Utility Model Content

[0072] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.

[0073] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0074] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0075] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.

[0076] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0077] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be positioned "above" the other component or feature. Thus, the exemplary term "below" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0078] The terms used herein are for the purpose of describing specific embodiments and are not intended to be restrictive. As used herein, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, the features, integral bodies, steps, operations, parts, assemblies and / or their groups stated are explained, but the presence or addition of one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups is not excluded. It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values ​​and / or the values ​​provided that will be recognized by those of ordinary skill in the art.

[0079] Figure 1 It is a structural schematic diagram of a workpiece detection system according to one embodiment of the present disclosure.

[0080] like Figure 1 As shown, the workpiece detection system of the present disclosure may include: a bracket 100, a first detection module 200, a carrying module 300 and a first driving device 400 and other components.

[0081] In actual use, the bracket 100 can be fixedly arranged near the production line, or the bracket 100 can be slidably arranged on the switching device 600. The solution of slidably arranging the bracket 100 on the switching device 600 will be described in detail below.

[0082] like Figure 1As shown, the bracket 100 is provided with an upper guide rail, and the number of the upper guide rails can be set to two. The two upper guide rails are parallel to each other and are horizontally arranged in a direction approaching or away from the tooling 900.

[0083] The carrying module 300 is slidably disposed on the upper guide rail, whereby the carrying module 300 can be driven to approach or move away from the tooling. Since the workpiece to be inspected is fixed on the tooling, the carrying module 300 can approach or move away from the workpiece.

[0084] The first detection module 200 is provided on the carrier module 300 , that is, the carrier module 300 of the present disclosure is used to carry the first detection module 200 , thereby enabling the first detection module 200 to approach or move away from the workpiece when the carrier module 300 approaches or moves away from the workpiece.

[0085] In the present disclosure, a first drive device 400 is disposed on the bracket 100 and is used to drive the carrier module 300 to move, thereby causing the first inspection module 200 to approach or move away from the first type of workpiece. In the present disclosure, the first drive device 400 can be a motor-driven ball screw structure, thereby achieving high motion precision for the carrier module 300 of the present disclosure. In particular, when a servo motor is selected, the carrier module 300 achieves even higher motion precision, enabling the first inspection module 200 to perform profile detection on a surface of the first type of workpiece.

[0086] Due to the special structure of the workpiece (such as a door hinge), at least two mounting holes are provided on the door part or the body part; the mounting holes on the door part can be distributed along the pivot axis direction of the door hinge, or in a direction perpendicular to the pivot axis of the door hinge; similarly, the mounting holes on the body part can also be distributed along the pivot axis direction of the door hinge, or in a direction perpendicular to the pivot axis of the door hinge. Therefore, the workpiece can be divided into a first type of workpiece and a second type of workpiece according to the distribution direction of the mounting holes during inspection.

[0087] In order to quickly detect the first type of workpiece and the second type of workpiece, the workpiece detection system of the present disclosure may further include: a second detection module 500, which is arranged on the carrier module 300 and is used to detect the second type of workpiece. As a result, when the carrier module 300 of the present disclosure approaches or moves away from the tooling 900, the first detection module 200 and the second detection module 500 can both approach or move away from the workpiece set on the tooling, but the first detection module 200 and the second detection module 500 do not work simultaneously. Instead, only the detection module aligned with the workpiece works and detects the workpiece.

[0088] Specifically, the workpiece detection system of the present disclosure may further include a switching device 600, which is used to drive the carrier module 300 to operate so that one of the first detection module 200 and the second detection module 500 corresponds to the position of the tooling 900. For example, at a certain moment, the first detection module 200 corresponds to the position of the tooling 900. When the next workpiece placed on the tooling 900 is a workpiece of the first type, the switching device 600 does not operate. When the next workpiece placed on the tooling 900 is a workpiece of the second type, the switching device 600 operates and drives the carrier module 300 to operate so that the second detection module 500 corresponds to the position of the tooling 900. At this time, the second detection module 500 detects the second type of workpiece.

[0089] Refer again Figure 1 The switching device 600 of the present disclosure may include a base 610 and a switching drive device 620. The base 610 may be a substantially horizontally disposed plate member, and may be provided with two lower guide rails disposed substantially parallel to each other. In a preferred embodiment, the lower guide rails extend perpendicularly or substantially perpendicularly to the upper guide rail.

[0090] The bracket 100 can be slidably arranged on the lower guide rail, so that the bracket 100 disclosed in the present invention can move along the arrangement direction of the first detection module 200 and the second detection module 500 on the supporting module 300. Accordingly, when the bracket 100 moves along the lower guide rail, the positions of the first detection module 200 and the second detection module 500 can be switched.

[0091] In other words, the first inspection module 200 and the second inspection module 500 of the present disclosure are horizontally arranged on the carrying module 300 and distributed along the extending direction of the lower guide rail.

[0092] The switching drive device 620 can be a cylinder, and it can be fixed on the base 610. Specifically, the cylinder body of the cylinder of the present disclosure can be fixed on the base 610, and the piston rod of the cylinder is fixed on the bracket 100, so that when the cylinder is actuated, it can drive the bracket 100 to reciprocate on the lower guide rail.

[0093] In a preferred embodiment, the workpiece inspection system of the present disclosure further includes a second drive device 700, which is used to drive the carrier module 300 to move and move the first inspection module 200 and the second inspection module 500 toward or away from the tooling 900. In other words, the carrier module 300 of the present disclosure can be driven by the first drive device 400 and the second drive device 700.

[0094] In the present disclosure, the second drive device 700 can be a cylinder. Due to the particularity of the cylinder movement, it can move quickly from one point to another. Therefore, when the workpiece detection system of the present disclosure is in use, the second drive device 700 can be put into operation first. At this time, the supporting module 300 will be quickly pushed from the initial position to the detection position or pushed to the vicinity of the detection position. At this time, the first drive device 400 is in a follow-up state. After the supporting module 300 reaches the detection position, the second drive device 700 no longer continues to work, but the first drive device 400 pushes the supporting module 300 to move forward slightly, so that the first detection module 200 and the second detection module 500 can contact the workpiece and complete the detection.

[0095] Preferably, the carrier module 300 and the second drive device 700 of the present disclosure are not fixedly connected. For example, a T-slot may be provided on the carrier module 300, and a T-block may be mounted on the second drive device 700. The T-block can be positioned within the T-slot and has a certain amount of movement margin. Thus, when the first drive device 400 drives the carrier module 300 to continue moving, the second drive device 700 will not affect the movement process. Of course, the workpiece detection system of the present disclosure can also achieve workpiece detection by operating only the first drive device 400.

[0096] Figures 2 to 6 1 is a schematic structural diagram of a first detection module and a second detection module at different angles according to an embodiment of the present disclosure. Figure 7 It is a partial structural diagram of a first detection module and a second detection module according to an embodiment of the present disclosure.

[0097] The following will be combined Figures 2 to 7 The structures of the first detection module and the second detection module of the present disclosure are described in detail.

[0098] like Figures 2 to 7 As shown, the first detection module 200 includes: a first base 210, a first upper contour detection plate 230, a first lower contour detection plate 240, a first upper hole detection component 250 and a first lower hole detection component 260 and other components.

[0099] Specifically, the first base 210 of the present disclosure is disposed on the supporting module 300. In a preferred embodiment, the first base 210 is a plate-shaped component and is disposed substantially vertically. Furthermore, the first base 210 can be substantially perpendicular to the extension direction of the upper guide rail.

[0100] The first upper profile detection plate 230 and the first lower profile detection plate 240 are each slidably mounted on the first base 210. Specifically, the first base 210 has a guide hole, within which a linear bearing can be mounted. A guide shaft is mounted within each linear bearing. The first upper profile detection plate 230 is mounted at one end of two guide shafts, while the first lower profile detection plate 240 is mounted at one end of the other two guide shafts. Accordingly, the other ends of the two upper guide shafts are connected to the first upper displacement sensor 270, thereby connecting the first upper profile detection plate 230 to the first upper displacement sensor 270. Similarly, the other ends of the two lower guide shafts are connected to the first lower displacement sensor 280, thereby connecting the first lower profile detection plate 240 to the first lower displacement sensor 280. In the present disclosure, the first upper displacement sensor 270 and the first lower displacement sensor 280 are arranged on the supporting module 300, so that when the first upper contour detection plate 230 contacts the workpiece, the workpiece can push the first upper contour detection plate 230 to move relative to the first base 210, thereby, the first upper displacement sensor 270 can detect the displacement value of the first upper contour detection plate 230; similarly, when the first lower contour detection plate 240 contacts the workpiece, the workpiece can push the first lower contour detection plate 240 to move relative to the first base 210, thereby, the first lower displacement sensor 280 can detect the displacement value of the first lower contour detection plate 240; accordingly, the displacement values ​​detected by the first upper displacement sensor 270 and the first lower displacement sensor 280 can obtain the contour of the surface of the workpiece in contact with the first upper contour detection plate 230 and the first lower contour detection plate 240.

[0101] In a preferred embodiment, the surfaces of the first upper profile detection plate 230 and the first lower profile detection plate 240 that are in contact with the workpiece are arranged on the same vertical plane.

[0102] In the present disclosure, the first upper contour detection plate 230 is located below the first lower contour detection plate 240 , that is, the first upper contour detection plate 230 and the first lower contour detection plate 240 are distributed in the vertical direction.

[0103] At least part of the first upper hole detection component 250 and the first lower hole detection component 260 can extend into the mounting hole of the first type of workpiece and retract from the mounting hole of the first type of workpiece; thus, the first upper hole detection component 250 and the first lower hole detection component 260 can be used to detect whether the position of the mounting hole on the workpiece is appropriate.

[0104] In a specific embodiment, the first upper hole detection assembly 250 of the present disclosure is located below the first lower hole detection assembly 260 , that is, the first upper hole detection assembly 250 and the first lower hole detection assembly 260 are distributed in the vertical direction.

[0105] In the present disclosure, the structures of the first upper hole detection assembly 250 and the first lower hole detection assembly 260 are the same. The structures of the first upper hole detection assembly 250 and the first lower hole detection assembly 260 are described below based on the structure of the first upper hole detection assembly 250.

[0106] Specifically, if Figure 6 and Figure 7 As shown, the first upper hole detection assembly 250 of the present disclosure includes: a first upper driving device 251 and a first upper telescopic rod 253, wherein the first upper telescopic rod 253 is slidably arranged on the first base 210, the first upper driving device 251 is used to drive the first upper telescopic rod 253 to produce telescopic movement, and the first upper driving device 251 is fixed to the first base 210.

[0107] That is to say, when the first upper hole detection component 250 of the present invention is working, its first upper telescopic rod 253 can be extended into the mounting hole of the workpiece; specifically, when the first upper telescopic rod 253 can be inserted into the mounting hole, it indicates that the mounting hole position of the workpiece is appropriate and the workpiece is a qualified product. When the first upper telescopic rod 253 cannot be inserted into the mounting hole, it indicates that the mounting hole position of the workpiece is not appropriate and the workpiece is an unqualified product.

[0108] In a preferred embodiment, the first upper contour detection plate 230 is provided with a through hole, through which the first upper telescopic rod 253 of the first upper hole detection assembly 250 can pass. The first lower contour detection plate 240 is provided with a groove, through which the first lower telescopic rod of the first lower hole detection assembly 260 can pass.

[0109] In the present disclosure, the first detection module 200 further includes: a first upper detection device 291 and a first lower detection device 293 and other components.

[0110] Among them, the first upper detection device 291 is used to detect the movement distance of the first upper telescopic rod 253 of the first upper hole detection assembly 250; the first lower detection device 293 is used to detect the movement distance of the first lower telescopic rod of the first lower hole detection assembly 260.

[0111] In the present disclosure, the first upper detection device 291 and the first lower detection device 293 are both beam switches or reflective switches. Taking the first upper hole detection assembly 250 as an example, the first upper telescopic rod 253 of the first upper hole detection assembly 250 has an elongated hole. In the initial state, the signal emitted by the first upper detection device 291 can be received by another beam switch (in the case of a beam switch); or the signal emitted by the first upper detection device 291 is not reflected by the first upper telescopic rod 253 (in the case of a reflective switch). When the first upper telescopic rod 253 is extended and properly inserted into the mounting hole, the signal emitted by the first upper detection device 291 cannot be received by another beam switch (in the case of a beam switch); or the signal emitted by the first upper detection device 291 is reflected by the first upper telescopic rod 253 (in the case of a reflective switch), indicating that the mounting hole is properly positioned. On the contrary, when the first upper telescopic rod 253 is driven to extend, if the first upper telescopic rod 253 is not correctly inserted into the mounting hole, the signal emitted by the first upper detection device 291 can be received by another beam switch (in the case of a beam switch); or the signal emitted by the first upper detection device 291 is not reflected by the first upper telescopic rod 253 (in the case of a reflective switch), then it indicates that the position of the mounting hole is unreasonable and the workpiece is an unqualified product.

[0112] like Figures 2 to 7 As shown, the second detection module 500 includes: a second base 510, a second upper contour detection plate 530, a second lower contour detection plate 540, a second left hole detection component 550 and a second right hole detection component 560 and other components.

[0113] Specifically, the second base 510 of the present disclosure is disposed on the supporting module 300. In a preferred embodiment, the second base 510 is a plate-shaped component and is disposed substantially vertically. Furthermore, the second base 510 can be substantially perpendicular to the extension direction of the upper guide rail.

[0114] The second upper profile detection plate 530 and the second lower profile detection plate 540 are slidably mounted on the second base 510. Specifically, the second base 510 has a guide hole, in which a linear bearing can be mounted. A guide shaft is mounted within the linear bearing. The second upper profile detection plate 530 is mounted at one end of the two guide shafts, and the second lower profile detection plate 540 is mounted at one end of the other two guide shafts. Accordingly, the other ends of the two upper guide shafts are connected to the second upper displacement sensor 570, thereby connecting the second upper profile detection plate 530 to the second upper displacement sensor 570. Similarly, the other ends of the two lower guide shafts are connected to the second lower displacement sensor 580, thereby connecting the second lower profile detection plate 540 to the second lower displacement sensor 580. In the present disclosure, the second upper displacement sensor 570 and the second lower displacement sensor 580 are arranged on the supporting module 300, so that when the second upper contour detection plate 530 contacts the workpiece, the workpiece can push the second upper contour detection plate 530 to move relative to the second base 510, thereby, the second upper displacement sensor 570 can detect the displacement value of the second upper contour detection plate 530; similarly, when the second lower contour detection plate 540 contacts the workpiece, the workpiece can push the second lower contour detection plate 540 to move relative to the second base 510, thereby, the second lower displacement sensor 580 can detect the displacement value of the second lower contour detection plate 540; accordingly, the displacement values ​​detected by the second upper displacement sensor 570 and the second lower displacement sensor 580 can obtain the contour of the surface of the workpiece in contact with the second upper contour detection plate 530 and the second lower contour detection plate 540.

[0115] Preferably, the surfaces of the second upper contour detection plate 530 and the second lower contour detection plate 540 that are in contact with the workpiece are arranged on the same vertical plane.

[0116] In the present disclosure, the second upper contour detection plate 530 is located below the second lower contour detection plate 540 , that is, the second upper contour detection plate 530 and the second lower contour detection plate 540 are distributed in the vertical direction.

[0117] At least part of the second left hole detection component 550 and the second right hole detection component 560 can extend into the mounting hole of the second type of workpiece and retract from the mounting hole of the second type of workpiece; thus, the second left hole detection component 550 and the second right hole detection component 560 can be used to detect whether the position of the mounting hole on the workpiece is appropriate.

[0118] In a specific embodiment, the second left hole detection component 550 of the present disclosure is located below the second right hole detection component 560, that is, the second left hole detection component 550 and the second right hole detection component 560 are distributed in the vertical direction.

[0119] In the present disclosure, the second left hole detection assembly 550 and the second right hole detection assembly 560 have the same structure. The structures of the second left hole detection assembly 550 and the second right hole detection assembly 560 will be described below based on the structure of the second left hole detection assembly 550.

[0120] Specifically, if Figure 6 and Figure 7 As shown, the second left hole detection assembly 550 of the present invention includes: a second left driving device 551 and a second left telescopic rod 553, wherein the second left telescopic rod 553 is slidably arranged on the second base 510, the second left driving device 551 is used to drive the second left telescopic rod 553 to produce telescopic movement, and the second left driving device 551 is fixed to the second base 510.

[0121] That is to say, when the second left hole detection component 550 of the present invention is working, its second left telescopic rod 553 can be extended into the mounting hole of the workpiece; specifically, when the second left telescopic rod 553 can be inserted into the mounting hole, it indicates that the mounting hole position of the workpiece is appropriate and the workpiece is a qualified product. When the second left telescopic rod 553 cannot be inserted into the mounting hole, it indicates that the mounting hole position of the workpiece is not appropriate and the workpiece is an unqualified product.

[0122] In a preferred embodiment, the second upper profile detection plate 530 and the second lower profile detection plate 540 are both provided with grooves, and the second left telescopic rod 553 of the second left hole detection assembly 550 can pass through the grooves of the second upper profile detection plate 530 and the second lower profile detection plate 540. The second upper profile detection plate 530 and the second lower profile detection plate 540 are both provided with grooves, and the second right telescopic rod of the second right hole detection assembly can pass through the grooves of the second upper profile detection plate 530 and the second lower profile detection plate 540.

[0123] In the present disclosure, the second detection module 500 further includes: a second left detection device 591 and a second right detection device 593 and other components.

[0124] Among them, the second left detection device 591 is used to detect the movement distance of the second left telescopic rod 553 of the second left hole detection assembly 550; the second right detection device 593 is used to detect the movement distance of the second right telescopic rod of the second right hole detection assembly 560.

[0125] In the present disclosure, the second left detection device 591 and the second right detection device 593 are both opposing beam switches or reflective switches. Taking the second left hole detection assembly 550 as an example, the second left telescopic rod 553 of the second left hole detection assembly 550 is provided with an elongated hole. In the initial state, the signal emitted by the second left detection device 591 can be received by another opposing beam switch (in the case of an opposing beam switch); or the signal emitted by the second left detection device 591 is not reflected by the second left telescopic rod 553 (in the case of a reflective switch). When the second left telescopic rod 553 is extended, if the second left telescopic rod 553 is correctly inserted into the mounting hole, the signal emitted by the second left detection device 591 cannot be received by another opposing beam switch (in the case of an opposing beam switch); or the signal emitted by the second left detection device 591 is reflected by the second left telescopic rod 553 (in the case of a reflective switch), indicating that the mounting hole is positioned appropriately. On the contrary, when the second left telescopic rod 553 is driven to extend, if the second left telescopic rod 553 is not correctly inserted into the mounting hole, the signal emitted by the second left detection device 591 can be received by another beam switch (in the case of a beam switch); or the signal emitted by the second left detection device 591 is not reflected by the second left telescopic rod 553 (in the case of a reflective switch), then it indicates that the position of the mounting hole is unreasonable and the workpiece is an unqualified product.

[0126] In the present disclosure, the first detection module 200 and the second detection module 500 may both include a thrust rod 800, which may be an elastic rod and is fixed to the supporting module 300, and one end of the thrust rod 800 may be able to extend from the first base 210 or the second base 510, so that when the supporting module 300 is driven to the detection position, the thrust rod 800 may be able to contact the workpiece and make the mounting surface of the workpiece in a roughly vertical position.

[0127] In the present disclosure, after the door hinge is assembled, it can be transferred from the production line to the tooling of the workpiece detection system of the present disclosure by a robot or manually, and inspected in the workpiece detection system, so that qualified products can enter the market, and unqualified products will be discarded, so that the workpiece detection system of the present disclosure can meet production requirements and ensure product qualification rate. At the same time, since the workpiece detection system of the present disclosure can complete hole position detection and contour detection, the equipment investment cost is reduced. Moreover, unlike the existing technology, the present disclosure detects the contour of the mounting surface by surface contact. On the one hand, it can ensure that the mounting surface is driven to a roughly vertical position, and on the other hand, the measurement result is more accurate.
