Description

Technical Field

[0001] The present application relates to the technical field of fastening equipment, and in particular to a gripper mounting assembly and a detection device. Background Art

[0002] In the production process of some products, it is necessary to detect the surface flatness of the product. Usually, a gripper mounting assembly is used to drive a proximity switch close to the surface of the product, and the proximity switch is used to detect the surface of the product, so as to achieve the purpose of detecting the surface flatness. However, the current gripper mounting assembly is fixedly connected to the proximity switch. When there are protrusions on the surface of the product, the product is likely to hit the proximity switch, causing the proximity switch to loosen and be damaged. At the same time, because the gripper mounting assembly is fixedly connected to the proximity switch, the relative position between the proximity switch and the product cannot be adjusted, resulting in the problem of inconvenience in using the proximity switch. Utility Model Content

[0003] In view of this, the present application provides a gripper mounting assembly, which realizes the function of floating setting of the proximity switch by setting an elastic member, and changes the relative position of the first limit member and the proximity switch by moving the first limit member along the first direction, thereby changing the relative position of the proximity switch and the mounting portion, and limits the first limit member and the second limit member respectively by the first limit member and the second limit member, thereby limiting the rotation of the first limit member and the second limit member relative to the proximity switch, thereby improving the stability of the proximity switch set on the mounting portion.

[0004] The present application provides a gripper mounting assembly including: a bracket, a first limiting member, a second limiting member and an elastic member. The bracket includes a first limiting portion, a mounting portion and a second limiting portion sequentially distributed along a first direction. The mounting portion is provided with a mounting hole along the first direction, and the mounting hole is used for a proximity switch to pass through. The first limiting portion has a first limiting surface facing the mounting hole in a direction perpendicular to the first direction, and the second limiting portion has a second limiting surface facing the mounting hole in a direction perpendicular to the first direction. The first limiting member is used to be sleeved on the proximity switch and located above the mounting portion. The first limiting member is also used to contact the mounting portion and limit the movement of the proximity switch moving along the first direction relative to the mounting portion. The second limiting member is used to be sleeved on the proximity switch and located below the mounting portion. The elastic member is used to be sleeved on the proximity switch and located between the mounting plate and the second limiting member; the second limiting member is also used to compress the elastic member toward the mounting portion, and the elastic member is used to buffer the second limiting member moving toward the mounting portion.

[0005] The gripper mounting assembly of the above-mentioned embodiment is configured with an elastic member so that when the proximity switch is subjected to an external force, the second limit member can compress the elastic member, thereby realizing the function of floating setting of the proximity switch. The first limit member is moved along the first direction to change the relative position of the first limit member and the proximity switch, thereby changing the relative position of the proximity switch and the mounting portion. The first limit member and the second limit member are respectively limited by the first limit member and the second limit member, thereby limiting the rotation of the first limit member and the second limit member relative to the proximity switch, thereby improving the stability of the proximity switch set on the mounting portion.

[0006] In some embodiments, the first limiting portion is provided with a first channel through which the first limiting member can movably pass along the first direction, and the first limiting surface is located on the surface of the first limiting portion facing the first channel. The second limiting portion is provided with a second channel through which the first limiting member and the elastic member can movably pass along the first direction, and the second limiting surface is located on the surface of the second limiting portion in the second channel.

[0007] In the above embodiment, the first limit surface is provided in the first channel and the second limit surface is provided in the second channel, so that the first limit member and the second limit member can respectively move relative to the mounting portion under the guiding action of the first channel and the second channel, while the first limit surface and the second limit surface respectively limit the first limit member and the second limit member from rotating relative to the proximity switch.

[0008] In some embodiments, the projection of the first limiting member in the first direction is a first polygon, and the cross-section of the first channel perpendicular to the first direction is a similar polygon to the first polygon; and / or the projection of the second limiting member in the first direction is a second polygon, and the cross-section of the second channel perpendicular to the first direction is a similar polygon to the second polygon.

[0009] In the above embodiment, by making the cross section of the first channel and the projection of the first limiting member similar polygons, and the cross section of the second channel and the projection of the second limiting member similar polygons, it is helpful to increase the contact area between the first channel and the first limiting member, and the contact area between the second channel and the second limiting surface, thereby improving the stability of the rotational limiting of the first limiting member and the second limiting member.

[0010] In some embodiments, when the second limiting portion is provided with a second channel, a through groove communicating with the second channel is opened on the second limiting portion along a direction perpendicular to the first direction.

[0011] In the above embodiment, the through groove is provided to facilitate discharge of impurities in the second through groove.

[0012] In some embodiments, the bracket also includes a connecting portion, which has a first part and a second part from top to bottom, the first part is used for fixed connection with the outside world, and the second part is used for connection with one side of the installation portion along the third direction.

[0013] In the above embodiment, the connection with the outside world is achieved through the connecting portion, so that the proximity switch is installed through the gripper installation assembly.

[0014] In some embodiments, a connecting hole is formed through the first portion along the second direction, and the connecting hole extends along the third direction.

[0015] In the above embodiment, the connecting hole is used to facilitate the gripper mounting assembly to drive the proximity switch to adjust the horizontal position.

[0016] In some embodiments, the elastic member is a compression spring.

[0017] In the above embodiment, the easily available compression spring helps to reduce the production cost.

[0018] In some embodiments, the mounting hole includes a first hole and a second hole, the first hole is located above the second hole, the diameter of the second hole is larger than the diameter of the first hole, and the second hole is also used to accommodate a portion of the elastic member.

[0019] In the above embodiment, the elastic member is located in the second hole to limit the elastic member, which helps to prevent the elastic member from deviating.

[0020] In some embodiments, when the proximity switch is moved downward a specified distance relative to the mounting portion by an external force, the second limit member can be separated from the second limit surface under the drive of the proximity switch, and the second limit member can also rotate relative to the proximity switch and move upward or downward.

[0021] In the above embodiment, when the first limit member moves up and down relative to the proximity switch, adjusting the second limit member to move relative to the proximity switch helps to keep the length of the compression spring consistent, thereby keeping the elastic effect of the compression spring unchanged.

[0022] A detection device: comprising a clamping assembly, a proximity switch and the above-mentioned gripper mounting assembly, wherein the mounting portion is connected to the clamping assembly, and the proximity switch passes through the mounting hole and is connected to a first stopper and a second stopper. The clamping assembly is used to drive the gripper mounting assembly and the proximity switch to approach a product, and the clamping assembly is also used to clamp the product. The proximity switch is used to detect the flatness of the surface of the product.

[0023] In the above embodiment, the gripper mounting assembly and the proximity switch are driven to move toward the product by the clamping assembly, so that when the clamping assembly clamps the product, the proximity switch can detect the surface of the product.

[0058] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0061] The term "several" means one, two or more and indicates an unlimited number.

[0062] It should be recognized that the dimensions of the structures shown in the drawings are given for better understanding and more convenient description, and the present application is not limited to the dimensions shown in the drawings. In order to make the present application clear, elements not related to the description are omitted from the details of this specification.

[0063] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0064] The present application provides a gripper mounting assembly including: a bracket, a first limiting member, a second limiting member and an elastic member. The bracket includes a first limiting portion, a mounting portion and a second limiting portion sequentially distributed along a first direction. The mounting portion is provided with a mounting hole along the first direction, and the mounting hole is used for a proximity switch to pass through. The first limiting portion has a first limiting surface facing the mounting hole in a direction perpendicular to the first direction, and the second limiting portion has a second limiting surface facing the mounting hole in a direction perpendicular to the first direction. The first limiting member is used to be sleeved on the proximity switch and located above the mounting portion. The first limiting member is also used to contact the mounting portion and limit the movement of the proximity switch moving along the first direction relative to the mounting portion. The second limiting member is used to be sleeved on the proximity switch and located below the mounting portion. The elastic member is used to be sleeved on the proximity switch and located between the mounting plate and the second limiting member; the second limiting member is also used to compress the elastic member toward the mounting portion, and the elastic member is used to buffer the second limiting member moving toward the mounting portion.

[0065] The gripper mounting assembly of the above-mentioned embodiment is configured with an elastic member so that when the proximity switch is subjected to an external force, the second limit member can compress the elastic member, thereby realizing the function of floating setting of the proximity switch. The first limit member is moved along the first direction to change the relative position of the first limit member and the proximity switch, thereby changing the relative position of the proximity switch and the mounting portion. The first limit member and the second limit member are respectively limited by the first limit member and the second limit member, thereby limiting the rotation of the first limit member and the second limit member relative to the proximity switch, thereby improving the stability of the proximity switch set on the mounting portion.

[0066] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0067] In this embodiment, the first direction X indicates a vertically upward direction, and the second direction Y and the third direction Z are both directions on a horizontal plane.

[0068] In other embodiments, the first direction X refers to a vertically downward direction, or refers to a direction forming an angle with the vertical direction.

[0069] See also Figure 1 A detection device 10 includes a clamping assembly 11, a proximity switch 12, and a gripper mounting assembly 13. The gripper mounting assembly 13 is connected to a side of the clamping assembly 11 facing the horizontal direction, and a mounting hole 13111 is formed on the gripper mounting assembly 13 along a first direction X. The proximity switch 12 passes through the mounting hole 13111 and is movably connected to the gripper mounting assembly 13.

[0070] When the clamping assembly 11 is moved close to the product 20 by an external force and obtains the product 20, the clamping assembly 11 drives the gripper mounting assembly 13 and the proximity switch 12 on the gripper mounting assembly 13 to move toward the product 20, so that the proximity switch 12 can detect the flatness of the surface of the product 20. When there is a protrusion on the surface of the product 20, the proximity switch 12 is movably connected with the gripper mounting assembly 13 so that the proximity switch 12 can move up and down relative to the gripper mounting assembly 13, thereby reducing the risk of damage between the proximity switch 12 and the product 20 due to rigid collision.

[0071] In some embodiments, the proximity switch 12 is a position switch that can work without direct contact with moving parts, and is generally used to measure the length and position of an object. Exemplarily, the proximity switch 12 is a displacement sensor. When an object enters the working range of the proximity switch 12, the proximity switch 12 sends a response signal, thereby achieving the purpose of detecting the position of the object. When applied to the flatness measurement of a surface, the object is moved close to the proximity switch 12 to a specified distance, and if the proximity switch 12 does not respond, it means that there is no protrusion on the surface of the object, thereby achieving the purpose of measuring the flatness of the surface of the object.

[0072] In some embodiments, see Figure 1 The clamping assembly 11 includes a clamping claw cylinder 111 or a lifting member (not shown) connected to a suction cup.

[0073] In some embodiments, see Figure 1 The proximity switch 12 includes two opposite ends, the upward end of the proximity switch 12 is used for electrical connection with an external controller, and the downward end of the proximity switch 12 is used for detecting the surface of the product 20.

[0074] In some embodiments, see Figures 2 to 4The gripper mounting assembly 13 includes a bracket 131, a first stopper 133, a second stopper 134 and an elastic member 132. When in use, the first stopper 133 is threadedly connected to an upward portion of the proximity switch 12, and the second stopper 134 is connected to a downward portion of the proximity switch 12. The bracket 131 includes a connecting portion 1312 and a first limiting portion 1313, a mounting portion 1311, and a second limiting portion 1314 sequentially distributed along the first direction X. The connecting portion 1312 is used to be fixedly connected to the clamping claw cylinder 111 of the clamping assembly 11. The mounting portion 1311 is located at one side of the connecting portion 1312 in the third direction Z. The mounting hole 13111 is located at the mounting portion 1311. The first limiting portion 1313 is located at the upward side of the mounting portion 1311. The first limiting portion 1313 has a first limiting surface 13131 facing the mounting hole 13111 in the horizontal direction. The second limiting portion 1314 is located at the downward side of the mounting portion 1311. The second limiting portion 1314 has a second limiting surface 13141 facing the mounting hole 13111 in the horizontal direction. The elastic member 132 has two opposite ends in the first direction X.

[0075] When the proximity switch 12 passes through the mounting hole 13111, the first limiting member 133 is threadedly connected to the portion of the proximity switch 12 extending upward from the mounting hole 13111, and the second limiting member 134 is threadedly connected to the portion of the proximity switch 12 extending downward from the mounting hole 13111. The elastic member 132 is located between the second limiting member 134 and the mounting portion 1311 in the first direction X. The second limiting member 134 and the mounting portion 1311 jointly compress the elastic member 132. The elastic member 132 acts downward on the second limiting member 134, and causes the second limiting member 134 to drive the proximity switch 12 and the first limiting member 133 on the proximity switch 12 to move downward. The mounting portion 1311 supports the first limiting member 133, thereby achieving the effect of installing the proximity switch 12 on the mounting portion 1311.

[0076] When the clamping assembly 11 drives the bracket 131 and the proximity switch 12 to move toward the product 20, and the surface of the product 20 contacts the top of the proximity switch 12, the product 20 supports the proximity switch 12, and the mounting portion 1311 compresses the elastic member 132, causing the proximity switch 12 to move upward relative to the bracket 131, thereby reducing the risk of damage caused by hard contact between the proximity switch 12 and the product 20.

[0077] At the same time, the proximity switch 12 is electrically connected to an external controller, and the proximity switch 12 is not easily rotated relative to the bracket 131 due to the limiting effect of the electrical connection line on the proximity switch 12. The first limiting surface 13131 of the first limiting portion 1313 acts on the first limiting member 133 to limit the first limiting member 133 from rotating relative to the bracket 131, and the second limiting surface 13141 of the second limiting portion 1314 acts on the second limiting member 134 to limit the second limiting member 134 from rotating relative to the bracket 131, thereby achieving the effect of the first limiting member 133 and the second limiting member 134 being relatively stationary with the proximity switch 12, improving the stability of the connection between the first limiting member 133 and the second limiting member 134 and the proximity switch 12, and reducing the risk of the proximity switch 12 easily falling off from the gripper mounting assembly 13.

[0078] When the proximity switch 12 is subjected to an external force and moves upward a specified distance relative to the mounting portion 1311 (the specified distance is greater than the length of the first limit surface 13131 in the first direction X), the second limit member 134 continues to compress the elastic member 132 under the drive of the proximity switch 12, and the first limit member 133 can be separated from the first limit surface 13131 under the drive of the proximity switch 12, thereby canceling the limiting effect of the first limit portion 1313 on the first limit member 133, and the external force acts on the first limit member 133, causing the first limit member 133 to rotate relative to the proximity switch 12 and move upward or downward, so that after the external force on the proximity switch 12 is canceled, the second limit member 134 drives the proximity switch 12 to move downward under the resetting effect of the elastic member 132, and causes the mounting portion 1311 to support the first limit member 133 again. Since the relative position of the first limit member 133 and the proximity switch 12 changes, when the mounting portion 1311 re-supports the first limit member 133, the relative position of the proximity switch 12 and the mounting portion 1311 also changes accordingly, thereby achieving the purpose of adjusting the relative position of the proximity switch 12 and the mounting portion 1311 in the first direction X, so that the relative height of the downward end of the proximity switch 12 changes, thereby satisfying the effect of the proximity switch 12 accurately detecting surfaces of different heights of the product 20.

[0079] In some embodiments, after adjusting the relative position between the first limit member 133 and the proximity switch 12, the distance between the first limit member 133 and the second limit member 134 will change, and the compression amount of the elastic member 132 by the second limit member 134 will also change accordingly, which will create a risk of increased error in the proximity switch 12 detecting the surface of the product 20, or when the elastic member 132 is compressed too much and cannot continue to be compressed, hard contact between the proximity switch 12 and the product 20 is likely to occur. When the proximity switch 12 is moved upward a specified distance relative to the mounting portion 1311 by an external force, the first limit member 133 can be separated from the first limit surface 13131 under the drive of the proximity switch 12, and after the first limit member 133 is removed from the proximity switch 12, the proximity switch 12 moves downward relative to the mounting portion 1311 under the action of gravity until the second limit member 134 is separated from the second limit surface 13141, and an external force acts on the second limit member 134 to make the second limit member 134 rotate relative to the proximity switch 12 and move upward or downward, so that the second limit member 134 can move synchronously with the first limit member 133, thereby achieving the effect of keeping the distance between the second limit members 134 and the second limit members 134 unchanged.

[0080] In some embodiments, see Figures 2 to 4 The first limiting portion 1313 is provided with a first channel 13132 for the first limiting member 133 to movably pass through along the first direction X, and the first limiting surface 13131 is a side wall of the first channel 13132. In addition, the second limiting portion 1314 is provided with a second channel 13142 for the first limiting member 133 and the elastic member 132 to movably pass through along the first direction X, and the second limiting surface 13141 is a side wall of the second channel 13142. When the proximity switch 12 is driven by an external force to move the first limit member 133 and the second limit member 134 along the first direction X relative to the bracket 131, the first channel 13132 and the second channel 13142 are set, so that the first channel 13132 can guide the movement of the first limit member 133, and the second channel 13142 can guide the movement of the second limit member 134, thereby improving the stability of the first limit member 133 and the second limit member 134 relative to the bracket 131 when the proximity switch 12 is driven by an external force. At the same time, when the proximity switch 12 drives the first limit member 133 and the second limit member 134 to move and reset, the first limit surface 13131 is arranged in the first channel 13132, and the second limit surface 13141 is arranged in the second channel 13142, so that the first limit surface 13131 and the second limit surface 13141 can quickly act on the first limit member 133 and the second limit member 134, so that the first limit surface 13131 and the second limit surface 13141 respectively limit the rotation of the first limit member 133 and the second limit member 134 relative to the proximity switch 12.

[0081] In some embodiments, the projection of the first stopper 133 in the first direction X is a first polygon, and the cross section of the first channel 13132 in the horizontal direction is a similar polygon to the first polygon; and / or the projection of the second stopper 134 in the first direction X is a second polygon, and the cross section of the second channel 13142 in the horizontal direction is a similar polygon to the second polygon. By making the cross section of the first channel 13132 and the projection of the first stopper 133 similar polygons, and the cross section of the second channel 13142 and the projection of the second stopper 134 similar polygons, it is helpful to increase the contact area between the first channel 13132 and the first stopper 133, and the contact area between the second channel 13142 and the second stopper surface 13141, thereby improving the stability of the rotation limit of the first stopper 133 and the second stopper 134.

[0082] In some embodiments, the projections of the first limit member 133 and the second limit member 134 in the first direction X and the cross-sections of the first channel 13132 and the second channel 13142 in the horizontal direction are both regular hexagons. Specifically, the first limit member 133 and the second limit member 134 are nuts. The easily available nuts help reduce the production costs of the first limit member 133 and the second limit member 134.

[0083] In other embodiments, the projections of the first limiting member 133 and the second limiting member 134 in the first direction X and the cross-sections of the first channel 13132 and the second channel 13142 in the horizontal direction are polygons such as regular triangles, squares, and regular pentagons, which are not limited here.

[0084] In other embodiments, a plurality of annular grooves (not shown) are provided on the proximity switch 12, and the first limit member 133 and the second limit member 134 are respectively U-shaped members (not shown), and the first limit member 133 and the second limit member 134 are respectively embedded in the annular grooves of the proximity switch 12, thereby achieving the purpose of connecting the first limit member 133 and the second limit member 134 to the proximity switch 12 respectively. When it is necessary to change the relative position of the first limit member 133 and the proximity switch 12 and / or the relative position of the second limit member 134 and the proximity switch 12, the first limit member 133 and / or the second limit member 134 are respectively embedded in different annular grooves of the proximity switch 12, thereby achieving the purpose of adjusting the relative position of the first limit member 133 and / or the second limit member 134 and the proximity switch 12 respectively.

[0085] In some embodiments, see Figure 4 and Figure 5The second limiting portion 1314 is provided with a through groove 13143 in the horizontal direction which is connected to the second channel 13142. When there are impurities such as oil, dust, etc. on the surface of the product 20, the impurities are easy to enter the second channel 13142, which hinders the elastic member 132 in the second channel 13142, causing the elastic coefficient of the elastic member 132 to become lower. The through groove 13143 is connected to the second channel 13142, which helps to discharge the impurities in the second channel 13142.

[0086] In some embodiments, see Figure 5 The mounting hole 13111 includes a first hole 13112 and a second hole 13113. The first hole 13112 is located above the second hole 13113. The diameter of the second hole 13113 is larger than the diameter of the first hole 13112, that is, the mounting hole 13111 is a stepped hole. The elastic member 132 is located in the second hole 13113 to limit the elastic member 132, which helps to prevent the elastic member 132 from deflecting.

[0087] In some embodiments, the elastic member 132 is an elastic member that is easily available, such as a compression spring (not shown) or a rubber block, which helps to reduce the production cost of the elastic member 132 .

[0088] In some embodiments, see Figure 4 The connecting portion 1312 has a first portion 13121 and a second portion 13122 from top to bottom. The first portion 13121 is provided with a connecting hole 13123 along the second direction Y. The second portion 13122 is connected to one side of the mounting portion 1311 in the second direction Y. Bolts are passed through the connecting hole 13123 to fix the first portion 13121 and the gripper cylinder 111, thereby achieving the effect of installing the proximity switch 12 on the clamping assembly 11 through the gripper mounting assembly 13.

[0089] In some embodiments, see Figure 4 The connecting hole 13123 extends along the third direction Z so that the connecting portion 1312 can move relative to the gripper cylinder 111 in the third direction Z, thereby achieving the purpose of the gripper mounting assembly 13 driving the proximity switch 12 to adjust the horizontal position, and meeting the purpose of the proximity switch 12 being able to adapt to the surfaces of products 20 of different sizes for detection.

[0090] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
