Abstract
Description
Technical Field
[0001] The present invention relates to the field of device manufacturing, and in particular to an intelligent production method of a terminal clamp and the terminal clamp. Background Art
[0002] Terminal pliers are a tool used to connect and secure wire terminals.
[0003] In the prior art, terminal clamps generally include a symmetrical and rotatably connected clamp body, which includes a clamp head and a clamp handle. By holding the clamp handle to drive the clamp head to generate shear force, the terminal is crimped to the cable through the clamp head. When manufacturing terminal clamps, it is generally necessary to rotatably connect one clamp body to the other clamp body and ensure the smoothness of the relative rotation of the clamp bodies.
[0004] When the pliers body does not rotate smoothly, the shear force generated by the pliers head is easily reduced, which makes it difficult for the terminal pliers to crimp the terminals. Summary of the Invention
[0005] In order to improve the convenience of using the terminal clamp and to check the smoothness of the rotation of the terminal clamp before leaving the factory, the present invention provides an intelligent production method of the terminal clamp and the terminal clamp.
[0006] In a first aspect, the present invention provides an intelligent production method for terminal pliers, which adopts the following technical solution:
[0007] An intelligent production method for terminal pliers, comprising:
[0008] Step 100: Acquire a detection image of the terminal clamp;
[0009] Step 101: determining a holding position in response to the detection image;
[0010] Step 102: determining a holding stroke in response to the holding position;
[0011] Step 103: controlling a preset detection device to clamp the holding position in response to the holding stroke, and controlling a preset detection device to close the holding position to collect the closing resistance of the terminal clamp;
[0012] Step 104: When the pulling and closing resistance is greater than a preset usage threshold, determining a protrusion timing in response to the pulling and closing resistance;
[0013] Step 105: determining a protrusion position in response to the protrusion moment;
[0014] Step 106: Control a preset control terminal to issue an alarm based on the protrusion position.
[0015] By adopting the above technical solution, the image of the pliers body is collected, and the detection device is used to hold the pliers handle and drive the pliers body to rotate to simulate the scene of the user actually using the terminal pliers, and the resistance to the rotation of the pliers body is recorded in real time to determine whether the rotation of the pliers body is smooth. Therefore, when the pliers body rotates poorly, the position of the protrusion on the pliers body can be quickly located, and the staff can be reminded through the control terminal to reduce the situation of poor rotation of the terminal pliers, thereby improving the convenience of using the terminal pliers.
[0016] Optionally, also include:
[0017] Step 107: When the closing resistance is greater than a preset usage threshold, determining the three-dimensional shape of the clamp body in response to the detection image;
[0018] Step 108: Determine the closing and closing stroke in response to the three-dimensional shape of the pliers and the protrusion moment;
[0019] Step 109: determining an overlap area in response to the pulling and closing stroke;
[0020] Step 110: In response to the overlapped area and the raised position, update the raised position to remove data in the raised position that falls within the overlapped area.
[0021] By adopting the above technical solution, when the resistance to the rotation of the pliers body is large, the outline of the pliers body when the resistance changes is used as the position where the protrusion may exist, and the position located on the back of the rotation direction is screened out in combination with the rotation direction of the pliers body, thereby improving the accuracy of the protrusion position.
[0022] Optionally, a method for determining a convex position is further included, and the method for determining a convex position includes:
[0023] Step 200: When the raised moment is empty, controlling a preset detection device to merge the gripping positions, and determining a test force in response to the pulling and closing resistance;
[0024] Step 201: generating a first test stroke and a second test stroke in response to the test force;
[0025] Step 202: controlling a preset detection device to press and lift any one of the holding positions according to the first test stroke, and collecting a first test resistance of the terminal clamp;
[0026] Step 203: determining a first test limit in response to the first test resistance, and controlling a preset detection device to open the gripping position according to a preset detection angle;
[0027] Step 204: controlling a preset detection device to press and lift any one of the gripping positions according to the second test stroke, and collecting a second test resistance of the terminal clamp;
[0028] Step 205: Determining a second test limit in response to the second test resistance;
[0029] Step 206: determining an overlap limit in response to the first test limit and the second test limit, and determining a rotational region in response to the caliper body in three dimensions;
[0030] Step 207: Determine the protrusion position in response to the overlap limit and the rotation area.
[0031] By adopting the above technical solution, when the protrusion is located in the part between the pliers that always overlap with each other, the resistance to the rotation of the pliers is always too high. At this time, a detection device is used to apply force to the pliers in a direction perpendicular to the rotation of the pliers to change the force conditions on both sides of the pliers with the rotation center of the pliers as the boundary, thereby adjusting the friction conditions on both sides of the pliers with the rotation center of the pliers as the boundary, and rotating the pliers again to identify the side where the protrusion is located. Finally, the angle is adjusted and tested again to reduce the area of the protrusion position, thereby improving the accuracy of the protrusion position.
[0032] Optionally, the method for determining the protrusion position further includes:
[0033] Step 208: determining a limit quantity in response to the overlap limit;
[0034] Step 209: When the number of limits is not 1, determining a separation angle in response to the overlap limit;
[0035] Step 210: generating a third test stroke in response to the separation angle;
[0036] Step 211: controlling a preset detection device to press and lift any one of the holding positions according to the third test stroke, and collecting a third test resistance of the terminal clamp;
[0037] Step 212: determining a third test limit in response to the third test resistance;
[0038] Step 213: Update the coincidence limit in response to the coincidence limit and a third test limit.
[0039] By adopting the above technical solution, when there are areas on both pliers that may have protrusions, the pliers are rotated by the detection device so that the areas on the pliers do not overlap, and then the pliers are applied with force and rotated in a direction perpendicular to the rotation direction of the pliers to screen out areas where no protrusions exist, thereby improving the accuracy of the protrusion position.
[0040] Optionally, the method for determining the protrusion position further includes:
[0041] Step 214: When the limit number is 1, determining a limit angle in response to the overlap limit;
[0042] Step 215: determining a test angle in response to the limit angle;
[0043] Step 216: generating a fourth test stroke in response to the test angle, and determining a qualified position in response to the overlap limit;
[0044] Step 217: Determine a test number in response to the qualified position;
[0045] Step 218: Based on the test number, controlling a preset detection device to press and lift the qualified position according to the fourth test stroke, and collecting a fourth test resistance of the terminal clamp;
[0046] Step 219: Determining a fourth test limit in response to the fourth test resistance;
[0047] Step 220: Determine a reduction limit in response to the overlap limit and the fourth test limit;
[0048] Step 221: When the reduction limit is consistent with the fourth test limit, update the overlap limit in response to the reduction limit.
[0049] By adopting the above technical solution, when there is a protrusion on only one pliers body, the other pliers body is rotated by the detection device so that the area where the protrusion exists on the pliers body is on a different side, and force is applied to the other pliers body again in a direction perpendicular to the rotation direction of the pliers body to narrow the range where the protrusion exists, thereby improving the accuracy of the protrusion position.
[0050] Optionally, a bulge recognition method is further included, and the bulge recognition method includes:
[0051] Step 300: Determine a clamp body angle in response to the protrusion position;
[0052] Step 301: determining an exposure angle in response to the angle of the clamp body;
[0053] Step 302: controlling a preset detection device to close the gripping position according to the exposed angle, and determining a sliding path in response to the raised position;
[0054] Step 303: determining a sliding force in response to the pulling and closing resistance;
[0055] Step 304: Based on the sliding path, controlling a preset sliding needle device to slide across the protruding position according to the sliding force, and collecting vibration of the needle body of the preset sliding needle device;
[0056] Step 305: determining the height of the clamp body in response to the vibration of the needle body;
[0057] Step 306: Update the protrusion position in response to the clamp body height.
[0058] By adopting the above technical solution, when there is a protrusion on the pliers body, the pliers body is pulled closed by the detection device to expose the protruding position, and the sliding needle device is used to slide across the protruding position to collect the vibration frequency of the sliding needle passing through the protruding position, so as to evaluate the flatness of the protruding position through the vibration frequency, thereby improving the accuracy of the protruding position.
[0059] Optionally, the bulge recognition method further includes:
[0060] Step 307: determining a protrusion distance in response to the protrusion position;
[0061] Step 308: determining a height threshold in response to the pulling-in resistance and the protrusion distance;
[0062] Step 309: When the height of the clamp body is lower than the height threshold, determining an area threshold in response to the height of the clamp body and the height threshold;
[0063] Step 310: determining a detection radius in response to the area threshold, and determining a subsequent area in response to the overlapping area;
[0064] Step 311: determining a sliding stroke in response to the subsequent area and the detection radius;
[0065] Step 312: Control the preset sliding needle device to slide across the surface of the clamp body according to the sliding stroke, and update the vibration of the needle body.
[0066] By adopting the above technical solution, the degree of obstruction to the rotation of the pliers body caused by protrusions of different positions, heights and areas is different. The minimum height of the protrusion with the minimum area that causes the corresponding resistance is evaluated based on the distance of the protrusion from the rotation center, so as to determine whether there are more protrusions. When there are more protrusions, the positions of other protrusions are detected by the sliding needle device, thereby improving the accuracy of the protrusion position.
[0067] Optionally, a convexity processing method is further included, and the convexity processing method includes:
[0068] Step 400: When the height of the clamp body is lower than a height threshold, determining a raised area in response to the raised position;
[0069] Step 401: determining a grinding force in response to the pliers body height;
[0070] Step 402: determining a grinding stroke in response to the grinding force and the raised area;
[0071] Step 403: Control the preset grinding device to grind the pliers body according to the grinding stroke.
[0072] By adopting the above technical solution, after confirming the range of the protrusion, the position of the protrusion is ground by a grinding device, thereby flattening the pliers body and reducing the situation where the protrusion blocks the pliers body from rotating relative to each other, thereby causing excessive resistance to pulling and closing the pliers body.
[0073] Optionally, the bulge processing method further includes:
[0074] Step 404: when the protrusion moment is empty, determining the pressing force in response to the pulling resistance;
[0075] Step 405: determining a pressing stroke in response to the test angle and the pressing force, and determining a grinding threshold in response to the pressing force;
[0076] Step 406: Based on the test number, controlling a preset detection device to press the qualified position according to the pressing stroke, and collecting the pressing resistance of the terminal clamp;
[0077] Step 407: When the pressing resistance is lower than the grinding threshold, the preset detection device is controlled to stop.
[0078] By adopting the above technical solution, when the protrusion is located in the part that always overlaps between the pliers, force is applied to the pliers handle to increase the friction of the pliers on the protrusion, so that the pliers are pulled back and forth by the detection device to grind the protrusion through the pliers.
[0079] In a second aspect, the present application provides a terminal clamp, which adopts the following technical solution:
[0080] A terminal clamp comprises a first clamp body, to which a second clamp body is rotatably connected, a fixed block is provided on the first clamp body in a direction perpendicular to the rotation direction of the first and second clamp bodies, a clamping block is rotatably connected on a side of the fixed block close to the second clamp body, and a torsion spring is fixed between the clamping block and the fixed block to drive the clamping block close to the fixed block.
[0081] In summary, this application includes at least one of the following beneficial technical effects:
[0082] The system captures an image of the clamp body, and uses a detection device to hold the clamp handle and drive the clamp body to rotate to simulate the user's actual use of the terminal clamp. The system also records the resistance to the clamp body's rotation in real time to determine whether the clamp body rotates smoothly. If the clamp body rotates poorly, the system quickly locates the location of the protrusion on the clamp body and alerts the operator through the control terminal to reduce the situation of poor rotation of the terminal clamp, thereby improving the convenience of using the terminal clamp.
[0083] When the resistance to the rotation of the caliper body is large, the contour of the caliper body when the resistance changes is used as the possible location of the protrusion, and the location on the back of the rotation direction is screened out in combination with the rotation direction of the caliper body, thereby improving the accuracy of the protrusion location;
[0084] When the protrusions are located in the parts of the pliers that always overlap with each other, the resistance to the rotation of the pliers is always too high. At this time, a detection device is used to apply force to the pliers in a direction perpendicular to the rotation of the pliers to change the force conditions on both sides of the pliers with the rotation center of the pliers as the boundary, thereby adjusting the friction conditions on both sides of the pliers with the rotation center of the pliers as the boundary, and rotating the pliers again to identify the side where the protrusion is located. Finally, adjust the angle and test again to reduce the area of the protrusion position, thereby improving the accuracy of the protrusion position. BRIEF DESCRIPTION OF THE DRAWINGS

[0094] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0095] Reference Figure 1The embodiment of the present application discloses a terminal clamp, comprising a first clamp body 1, a second clamp body 2, a fixed block 3, a clamping block 4 and a torsion spring 5. The second clamp body 2 is rotatably connected to the first clamp body 1, and the first clamp body 1 and the second clamp body 2 rotate with each other to generate a shear force, thereby fixing the terminal on the cable. The fixed block 3 is bolted to the first clamp body 1 in a direction perpendicular to the rotation direction of the first clamp body 1 and the second clamp body 2. The clamping block 4 is rotatably connected to the side of the fixed block 3 close to the second clamp body 2. The clamping block 4 and the fixed block 3 are fixed by bolts. The torsion spring 5 is fixed between the clamping block 4 and the fixed block 3. The torsion spring 5 is used to drive the clamping block 4 close to the fixed block 3 to clamp the cable.
[0096] Reference Figure 2 , an intelligent production method for terminal clamps, comprising:
[0097] Step 100: Acquire a detection image of the terminal clamp.
[0098] The detection image refers to a picture of the terminal clamp after installation, which can be collected by a camera fixed on the assembly line, where the assembly line refers to an assembly line used to produce and assemble the terminal clamp. The detection image collection method is selected by the staff based on the actual situation and will not be elaborated here.
[0099] Step 101: Determine a holding position in response to the detection image.
[0100] The gripping position refers to the position information of the gripper handles on the first and second gripper bodies 1 and 2 . The gripping position can be identified by image recognition technology. The method for identifying the gripping position is common knowledge in this field and will not be elaborated here.
[0101] Step 102: Determine a holding stroke in response to the holding position.
[0102] The detection device is a device used to drive the relative rotation of the first and second jaw bodies 1 and 2. A robotic arm is typically used. The detection device is selected by the operator based on actual conditions and is not described in detail here. The gripping stroke refers to the path along which the detection device clamps the gripping positions. The method for determining the gripping stroke is common knowledge in the art and is not described here.
[0103] Step 103: In response to the gripping stroke, a preset detection device is controlled to clamp the gripping position, and a preset detection device is controlled to close the gripping position to collect the closing resistance of the terminal clamp.
[0104] The pulling and closing resistance refers to the resistance encountered by the detection device when opening and closing the pliers handle. The pulling and closing resistance can be collected by a pressure sensor fixed on the detection device. The method of collecting the pulling and closing resistance is selected by the staff according to actual conditions and will not be elaborated here.
[0105] Step 104: When the pulling-closing resistance is greater than a preset usage threshold, determining a protrusion moment in response to the pulling-closing resistance.
[0106] The usage threshold refers to the maximum resistance during normal rotation of the terminal clamp. The usage threshold is selected by the operator based on actual conditions and is not detailed here. A closing resistance greater than the usage threshold indicates excessive resistance, meaning there is a protrusion on the terminal clamp that hinders the relative rotation of the clamp bodies. The moment the protrusion contacts the clamp bodies is when the clamp bodies make contact. The closing resistance is generally determined by the moment when the closing resistance suddenly increases or decreases. Methods for determining the closing resistance are common knowledge in the art and are not detailed here.
[0107] Step 105: Determine a protrusion position in response to the protrusion moment.
[0108] The raised position refers to the position of the raised portion on the pliers body. Generally, the contour line of the first pliers body 1 on the second pliers body 2 and the contour line of the second pliers body 2 on the first pliers body 1 at the raised moment are used as the raised position. The method for determining the raised position is common knowledge among people in this field and will not be elaborated here.
[0109] Step 106: Control a preset control terminal to issue an alarm based on the protrusion position.
[0110] The control terminal refers to a device used to notify the staff that there is a protrusion on the clamp body that prevents the clamp bodies from rotating relative to each other. The control terminal is selected by the staff based on actual conditions and will not be described in detail here.
[0111] The image of the pliers body is collected, and the detection device is used to hold the pliers handle and drive the pliers body to rotate to simulate the scene of the user actually using the terminal pliers. The resistance of the pliers body rotation is recorded in real time to determine whether the pliers body rotates smoothly. When the pliers body rotates poorly, the position where the resistance exists on the pliers body can be quickly located. The control terminal can remind the staff to reduce the situation of poor rotation of the terminal pliers, thereby improving the convenience of using the terminal pliers.
[0112] Reference Figure 3 , an intelligent production method for terminal pliers, further comprising:
[0113] Step 107: When the pulling and closing resistance is greater than a preset usage threshold, determine the three-dimensional shape of the clamp body in response to the detection image.
[0114] The three-dimensional clamp body refers to the three-dimensional model data of the clamp body. The outer contours of the first clamp body 1 and the second clamp body 2 can be identified from the detection image through image recognition technology to obtain the three-dimensional clamp body. The method for determining the three-dimensional clamp body is common knowledge among people in this field and will not be elaborated here.
[0115] Step 108: Determine the pulling and closing stroke in response to the three-dimensional shape of the pliers body and the protrusion moment.
[0116] The closing stroke refers to the range of rotation of the first pliers body 1 and the second pliers body 2 before the protrusion moment. The method for determining the closing stroke is common knowledge in this field and will not be elaborated here.
[0117] Step 109: Determine an overlapping area in response to the pulling and closing stroke.
[0118] The overlapping area is the area where the first pliers body 1 passes on the second pliers body 2 and the area where the second pliers body 2 passes on the first pliers body 1 during the pulling and closing stroke. The method for determining the overlapping area is common knowledge among people in this field and will not be elaborated here.
[0119] Step 110: In response to the overlapped area and the raised position, update the raised position to remove data in the raised position that falls within the overlapped area.
[0120] When the resistance to the rotation of the caliper body is large, the outline of the caliper body when the resistance changes is used as the position where the large resistance may exist, and the position located on the back of the rotation direction is screened out in combination with the rotation direction of the caliper body, thereby improving the accuracy of the protrusion position.
[0121] Reference Figure 4 , the method for determining the protrusion position includes:
[0122] Step 200: When the raised moment is empty, control a preset detection device to merge the holding positions, and determine a test force in response to the pulling and closing resistance.
[0123] When the protrusion is empty at the moment, it means that the pulling resistance is always high, that is, the protrusion is located in the part that always overlaps between the first pliers body 1 and the second pliers body 2. The combined gripping position is to pull the first pliers body 1 and the second pliers body 2 together until the angles of the first pliers body 1 and the second pliers body 2 are consistent. The test force refers to the force used to move the first pliers body 1 and the second pliers body 2 closer to and away from each other. The smaller the pulling resistance, the less obvious the obstruction of the protrusion on the pliers body. At this time, a larger test force is used to highlight the obstruction of the protrusion on the pliers body. The test force can be obtained from the test correspondence table. The test correspondence table refers to a data table that records different pulling resistances and their corresponding test forces.
[0124] Step 201: Generate a first test stroke and a second test stroke in response to the test force.
[0125] The first test stroke refers to the route of pressing and lifting the caliper bodies respectively through the detection device when the angles of the first caliper body 1 and the second caliper body 2 are consistent, and pressing any holding position through the detection device to make the first caliper body 1 and the second caliper body 2 on the side close to the holding position from the rotation center approach each other, and the first caliper body 1 and the second caliper body 2 on the side away from the holding position from the rotation center move away from each other, thereby increasing the obstruction effect of the protrusion between the first caliper body 1 and the second caliper body 2 on the side close to the holding position from the rotation center, and reducing the obstruction effect of the protrusion between the first caliper body 1 and the second caliper body 2 on the side away from the holding position from the rotation center, and lifting any holding position through the detection device to make the first caliper body 1 and the second caliper body 2 on the side close to the holding position from the rotation center The bodies 2 move away from each other, and the first pliers body 1 and the second pliers body 2 on the side away from the gripping position from the rotation center move closer to each other, thereby reducing the obstruction of the protrusion between the first pliers body 1 and the second pliers body 2 on the side close to the gripping position from the rotation center, and increasing the obstruction of the protrusion between the first pliers body 1 and the second pliers body 2 on the side away from the gripping position from the rotation center. The pulling resistance of the pliers bodies when the detection device is pressed and the pulling resistance of the pliers bodies when the detection device is lifted are compared to determine whether the protrusion is located between the first pliers body 1 and the second pliers body 2 on the side away from the gripping position from the rotation center or between the first pliers body 1 and the second pliers body 2 on the side close to the gripping position from the rotation center. The method for generating the first test stroke is common knowledge known to people in this field and will not be described here.
[0126] The detection angle refers to the angle between the first and second jaws 1, 2. The detection angle is generally selected from the angle closest to 180 degrees within the range of rotation between the first and second jaws 1, 2. The detection angle is selected by the operator based on actual conditions and is not detailed here. The second test stroke refers to the path of the jaws 1 and 2, respectively, when the detection angle is established between the first and second jaws 1, 2. The method for generating the second test stroke refers to the method for generating the first test stroke described above.
[0127] Step 202: Control a preset detection device to press and lift any one of the holding positions according to the first test stroke, and collect a first test resistance of the terminal clamp.
[0128] The first test resistance is the resistance encountered by the detection device when opening and closing the pliers handle when pressing and lifting the holding position according to the first test stroke. The first test resistance can be collected by a pressure sensor fixed on the detection device. The method of collecting the first test resistance is selected by the staff according to actual conditions and will not be elaborated here.
[0129] Step 203: Determine a first test limit in response to the first test resistance, and control a preset detection device to open the holding position according to a preset detection angle.
[0130] The first test limit refers to the angular range in which the protrusion may exist on the first pliers body 1 and the second pliers body 2. If the resistance when pressing the gripping position and pulling the pliers body together according to the first stroke is greater than the resistance when lifting the gripping position and pulling the pliers body together, the protrusion is located between the first pliers body 1 and the second pliers body 2 on the side closer to the gripping position from the rotation center; otherwise, the protrusion is located between the first pliers body 1 and the second pliers body 2 on the side away from the gripping position from the rotation center.
[0131] Step 204: Control the preset detection device to press and lift any one of the holding positions according to the second test stroke, and collect the second test resistance of the terminal clamp.
[0132] The second test resistance is the resistance encountered by the detection device when opening and closing the clamp handle when pressing and lifting the holding position according to the second test stroke. The method for collecting the second test resistance refers to the above-mentioned first test resistance.
[0133] Step 205: Determine a second test limit in response to the second test resistance.
[0134] The second test limit refers to the angle range in which the protrusion may exist on the first pliers body 1 and the second pliers body 2. The method for determining the second test limit refers to the first test limit mentioned above.
[0135] Step 206: Determine an overlap limit in response to the first test limit and the second test limit, and determine a rotation area in three dimensions in response to the clamp body.
[0136] The overlap limit refers to the angular range of the overlapping part of the first test limit and the second test limit, that is, the angular range of the overlapping part of the first test limit and the second test limit located on the first clamp body 1 and the overlapping part located on the second clamp body 2. The method for determining the overlap limit is common knowledge among people in this field and will not be elaborated here.
[0137] The rotation area is the partial area where the first pliers 1 and the second pliers 2 always overlap when they rotate relative to each other. At this time, the raised position is the position information within the overlapping limit in the rotation area. The method for determining the rotation area is common knowledge among people in this field and will not be elaborated here.
[0138] Step 207: Determine the protrusion position in response to the overlap limit and the rotation area.
[0139] When the protrusions are located in the parts of the pliers that always overlap with each other, the resistance to the rotation of the pliers is always too high. At this time, a detection device is used to apply force to the pliers in a direction perpendicular to the rotation of the pliers to change the force conditions on both sides of the pliers with the rotation center of the pliers as the boundary, thereby adjusting the friction conditions on both sides of the pliers with the rotation center of the pliers as the boundary, and rotating the pliers again to identify the side where the protrusion is located. Finally, adjust the angle and test again to reduce the area of the protrusion position, thereby improving the accuracy of the protrusion position.
[0140] Reference Figure 5 , the method for determining the protrusion position further includes:
[0141] Step 208: Determine a limit quantity in response to the coincident limit.
[0142] The number of boundaries is the number of pliers in the overlapping boundary. When the overlapping boundary exists only on the first pliers 1 or the second pliers 2, the number of boundaries is 1. When the overlapping boundary exists on both the first pliers 1 and the second pliers 2, the number of boundaries is 2.
[0143] Step 209: When the limit number is not 1, determining a separation angle in response to the overlap limit.
[0144] The fact that the number of boundaries is not 1 indicates that there are overlapping boundaries on both the first pliers body 1 and the second pliers body 2. The separation angle refers to the minimum angle value for separating the overlapping boundaries on the first pliers body 1 from the overlapping boundaries on the second pliers body 2. The method for determining the separation angle is common knowledge among people in this field and will not be elaborated here.
[0145] Step 210 : Generate a third test stroke in response to the separation angle.
[0146] The third test stroke refers to a route in which the first caliper body 1 and the second caliper body 2 are pressed and lifted respectively by the detection device when the first caliper body 1 and the second caliper body 2 are separated at an angle. The method for generating the third test stroke refers to the first test stroke.
[0147] Step 211: controlling a preset detection device to press and lift any one of the holding positions according to the third test stroke, and collecting a third test resistance of the terminal clamp.
[0148] The third test resistance is the resistance encountered by the detection device when opening and closing the clamp handle when pressing and lifting the holding position according to the third test stroke. The method for collecting the third test resistance refers to the above-mentioned first test resistance.
[0149] Step 212: Determine a third test limit in response to the third test resistance.
[0150] The third test limit refers to the angle range in which the protrusion may exist on the first pliers body 1 and the second pliers body 2. The method for determining the third test limit refers to the first test limit mentioned above.
[0151] Step 213: Update the coincidence limit in response to the coincidence limit and a third test limit.
[0152] When there are areas on both pliers that may have resistance, the pliers are rotated by the detection device so that the areas on the pliers do not overlap. The pliers are then subjected to force and rotated in a direction perpendicular to the rotation direction of the pliers to screen out areas where there is no resistance, thereby improving the accuracy of the protrusion position.
[0153] Reference Figure 6 , the method for determining the protrusion position further includes:
[0154] Step 214: When the limit number is 1, determine a limit angle in response to the overlap limit.
[0155] A limit number of 1 indicates that there is an overlap limit only on the first clamp body 1 or the second clamp body 2. The limit angle refers to the angle value of the midpoint of the overlap limit. The method for determining the limit angle is common knowledge in this field and will not be elaborated here.
[0156] Step 215: Determine a test angle in response to the limit angle.
[0157] The test angle refers to the angle value obtained by rotating the first clamp body 1 or the second clamp body 2 so that the overlapping limit is evenly divided into two sides. It can be determined by adding or subtracting 90 degrees from the limit angle. The method for determining the test angle is common knowledge among people in this field and will not be elaborated here.
[0158] Step 216 : Generate a fourth test stroke in response to the test angle, and determine a qualified position in response to the overlap limit.
[0159] The fourth test stroke refers to a route in which the first caliper body 1 and the second caliper body 2 are pressed and lifted respectively by the detection device when the test angle is formed between the first caliper body 1 and the second caliper body 2. The method for generating the fourth test stroke refers to the first test stroke.
[0160] The qualified position refers to the gripping position of one of the first clamp body 1 and the second clamp body 2 where no overlap occurs. The method for determining the qualified position is common knowledge among those skilled in the art and will not be elaborated herein.
[0161] Step 217: Determine a test number in response to the qualified position.
[0162] The test number refers to the number value of the detection device for the qualified clamping position. The method for determining the test number is common knowledge among people in this field and will not be described in detail here.
[0163] Step 218: Based on the test number, control the preset detection device to press and lift the qualified position according to the fourth test stroke, and collect the fourth test resistance of the terminal clamp.
[0164] The fourth test resistance is the resistance encountered by the detection device when opening and closing the clamp handle when pressing and lifting the qualified position according to the fourth test stroke. The method for collecting the third test resistance refers to the above-mentioned first test resistance.
[0165] Step 219: Determine a fourth test limit in response to the fourth test resistance.
[0166] The fourth test limit refers to the angle range in which the protrusion may exist on the first pliers body 1 and the second pliers body 2. The method for determining the fourth test limit refers to the above-mentioned first test limit.
[0167] Step 220: Determine a reduction limit in response to the coincidence limit and a fourth test limit.
[0168] The reduction limit refers to the overlapping portion of the overlap limit and the fourth test limit. The method for determining the reduction limit is common knowledge to those skilled in the art and will not be elaborated here.
[0169] Step 221: When the reduction limit is consistent with the fourth test limit, update the overlap limit in response to the reduction limit.
[0170] If the reduction limit is consistent with the fourth test limit, it means that the overlap limit cannot be further reduced. At this time, the reduction limit is used as the most accurate overlap limit. If the reduction limit is inconsistent with the fourth test limit, it means that the overlap limit can be further reduced. At this time, the above steps are repeated until the reduction limit is consistent with the fourth test limit.
[0171] When resistance exists on only one pliers body, the detection device rotates the other pliers body so that the area where resistance exists on the pliers body is on a different side, and force is applied to the other pliers body again in a direction perpendicular to the rotation direction of the pliers body to narrow the range where resistance exists, thereby improving the accuracy of the protrusion position.
[0172] Reference Figure 7 , bulge recognition methods include:
[0173] Step 300: Determine a jaw body angle in response to the protrusion position.
[0174] The jaw body angle refers to the angle between the first jaw body 1 and the second jaw body 2 when the first jaw body 1 or the second jaw body 2 is in the raised position. The method for determining the jaw body angle is common knowledge in this field and will not be elaborated here.
[0175] Step 301: Determine an extension angle in response to the angle of the jaw body.
[0176] The exposure angle refers to the angle between the first jaw body 1 and the second jaw body 2 when the protruding position is exposed. Generally, an angle lower than the jaw body angle is used as the exposure angle. The method for determining the exposure angle is selected by the staff according to actual conditions and will not be elaborated here.
[0177] Step 302: Control a preset detection device to pull and close the holding position according to the exposed angle, and determine a sliding path in response to the protruding position.
[0178] The sliding needle device is a device used to slide across the surface of the pliers and collect the needle's vibrations. The selection of the sliding needle device is determined by the operator based on the actual situation and is not detailed here. The sliding path is the path that the sliding needle device sequentially slides across the raised positions. The method for determining the sliding path is common knowledge in the art and is not detailed here.
[0179] Step 303: Determine the sliding force in response to the pulling and closing resistance.
[0180] The sliding force is the force with which the pointer body presses against the surface of the pliers body. When the pulling resistance is large, it means that the height of the protrusion is high. At this time, a lower sliding force is used to reduce damage to the needle body. The sliding force can be obtained from the sliding correspondence table, which is a data table that records different pulling resistances and their corresponding sliding forces.
[0181] Step 304: Based on the sliding path, a preset sliding needle device is controlled to slide across the protruding position according to the sliding force, and vibration of the needle body of the preset sliding needle device is collected.
[0182] The needle body vibration is the vibration frequency of the needle body of the sliding needle device. The method for collecting the needle body vibration is selected by the staff according to the actual situation and will not be described in detail here.
[0183] Step 305: Determine the height of the clamp body in response to the needle body vibration.
[0184] The height of the clamp body refers to the drop value on the surface of the clamp body. When there is a protrusion on the surface of the clamp body, the needle body slides over the protrusion, causing the needle body to be squeezed by the protrusion, thereby increasing the pressure of the needle body on the protrusion, thereby increasing the vibration frequency of the needle body. The drop value on the surface of the clamp body is judged by the vibration frequency. The method for determining the height of the clamp body is common knowledge among people in this field and will not be elaborated here.
[0185] Step 306: Update the protrusion position in response to the clamp body height.
[0186] When there is resistance on the pliers body, the pliers body is pulled closed by the detection device to expose the raised position, and the sliding needle device is used to slide across the raised position to collect the vibration frequency of the sliding needle passing through the raised position, so as to evaluate the flatness of the raised position through the vibration frequency, thereby improving the accuracy of the raised position.
[0187] Reference Figure 8 , the bulge recognition method further includes:
[0188] Step 307: Determine a protrusion distance in response to the protrusion position.
[0189] The raised distance refers to the distance between the raised position and the rotation position. The rotation position refers to the position of the rotation midpoint of the first clamp body 1 and the second clamp body 2. The rotation position is pre-set by the staff. The method for determining the raised distance is common knowledge among people in this field and will not be elaborated here.
[0190] Step 308: Determine a height threshold in response to the pull-in resistance and the protrusion distance.
[0191] The height threshold refers to the minimum height value of the protrusion required to form the pulling and closing resistance under the protrusion distance. The maximum change value of the resistance in the pulling and closing resistance can be calculated first, that is, the difference between the maximum and minimum values of the pulling and closing resistance, and then the height threshold corresponding to the maximum change value can be obtained from the height relationship table. The height relationship table refers to a data table that records the height thresholds corresponding to different maximum change values and protrusion distances.
[0192] Step 309: When the height of the clamp body is lower than the height threshold, determine an area threshold in response to the height of the clamp body and the height threshold.
[0193] If the jaw body height is lower than the height threshold, it means that the protrusion at the jaw body height is unlikely to cause closing resistance. This indicates that there are other protrusions besides the protrusion position. The area threshold refers to the minimum area value required to cause closing resistance when the protrusion at the jaw body height is located at the protrusion distance. The area threshold can be determined by the formula: height threshold = (jaw body height * area threshold).
[0194] Step 310: Determine a detection radius in response to the area threshold, and determine a subsequent area in response to the overlapping area.
[0195] The detection radius refers to the radius of the area where the remaining protrusions are found by the sliding needle device. The diameter value of the circle of the area threshold can be used as the detection radius. The method for determining the detection radius is selected by the staff according to the actual situation and will not be elaborated here.
[0196] The subsequent area refers to the area on the clamp body that has not been rotated, that is, the area remaining on the first clamp body 1 and the second clamp body 2 except the overlapping area. The method for determining the subsequent area is common knowledge among people in this field and will not be described here.
[0197] Step 311: Determine a sliding stroke in response to the subsequent area and the detection radius.
[0198] The sliding stroke refers to the route that the sliding needle device slides on the overlapping part of the circle with the raised position as the center and the detection radius as the radius and the subsequent area. The method for determining the sliding stroke is common knowledge among people in this field and will not be elaborated here.
[0199] Step 312: Control the preset sliding needle device to slide across the surface of the clamp body according to the sliding stroke, and update the vibration of the needle body.
[0200] The degree of obstruction to the rotation of the pliers body caused by resistance at different positions, heights and areas is different. The minimum height of the minimum area protrusion required to cause the corresponding resistance is evaluated according to the position of the protrusion, so as to determine whether there are more protrusions. If there are more protrusions, the position of other protrusions can be detected by sliding the needle, thereby improving the accuracy of the protrusion position.
[0201] Also included is a convex treatment method, which includes:
[0202] Step 400: When the height of the clamp body is lower than a height threshold, determine a raised area in response to the raised position.
[0203] The raised area refers to the area range formed by integrating densely distributed raised positions. By integrating the raised areas, the amount of calculation during grinding is reduced. The method for determining the raised area is common knowledge among people in this field and will not be elaborated here.
[0204] Step 401: Determine a grinding force in response to the pliers body height.
[0205] The grinding device refers to a device used to grind the pliers body to remove protrusions. The grinding device is selected by the staff according to actual conditions and will not be described here.
[0206] Grinding force refers to the force with which the grinding device presses the raised position. The higher the pliers height, the greater the grinding force required to improve grinding efficiency. The grinding force can be obtained from the grinding relationship table, which is a data table that records different pliers heights and their corresponding grinding forces.
[0207] Step 402: Determine a grinding stroke in response to the grinding force and the raised area.
[0208] The grinding stroke is the route along which the grinding device grinds the raised area according to the grinding force. The method for determining the grinding stroke is common knowledge among those skilled in the art and will not be elaborated here.
[0209] Step 403: Control the preset grinding device to grind the pliers body according to the grinding stroke.
[0210] After the range of the protrusion is confirmed, the position of the protrusion is ground by a grinding device, thereby flattening the pliers body and reducing the situation where the protrusion blocks the pliers body from rotating relative to each other, thereby causing excessive resistance to pulling and closing the pliers body.
[0211] Bump treatment methods also include:
[0212] Step 404: When the protrusion moment is empty, determine the pressing force in response to the pulling resistance.
[0213] The pressing force refers to the force value used to drive the first pliers body 1 and the second pliers body 2 closer to each other through the testing device, driving the first pliers body 1 and the second pliers body 2 closer to each other to increase the friction between the protrusion and the pliers body, thereby increasing the grinding effect of the pliers body on the protrusion. The greater the maximum change value of the resistance in the pulling resistance, the greater the pressing force used. The pressing force can be obtained from the pressing relationship table. The pressing relationship table refers to a data table that records different maximum change values and their corresponding pressing forces.
[0214] Step 405: Determine a pressing stroke in response to the test angle and the pressing force, and determine a grinding threshold in response to the pressing force.
[0215] The pressing stroke refers to the route in which the detection device that controls the test number pulls the pliers apart until the first pliers 1 and the second pliers 2 are at a test angle, drives the first pliers 1 and the second pliers 2 closer to each other with the pressing force, and then drives the pliers to rotate relative to each other back and forth. The method for determining the pressing stroke is common knowledge among people in this field and will not be elaborated here.
[0216] The grinding threshold refers to the maximum normal value of the resistance when the pliers rotate under the pressing force. The grinding threshold can be obtained from the threshold relationship table. The threshold relationship table refers to a data table that records different pressing forces and their corresponding grinding thresholds.
[0217] Step 406: Based on the test number, a preset detection device is controlled to press the qualified position according to the pressing stroke, and the pressing resistance of the terminal clamp is collected.
[0218] The pressing resistance is the resistance encountered by the detection device when it reciprocates to open and close the clamp handle when pressing the qualified position according to the pressing stroke. The method for collecting the pressing resistance refers to the first test resistance mentioned above.
[0219] Step 407: When the pressing resistance is lower than the grinding threshold, the preset detection device is controlled to stop.
[0220] When the pressing resistance is lower than the grinding threshold, it means that the resistance between the pliers has returned to normal. At this time, stop rotating the pliers to reduce wear on the pliers.
[0221] When the protrusion is located at the part where the pliers bodies always overlap, force is applied to the pliers handle to increase the friction force of the pliers bodies on the protrusion, so that the pliers bodies are pulled back and forth by the detection device to grind the protrusion through the pliers bodies.
