Abstract

This disclosure relates to the field of clamping tooling technology, and more particularly to a clamping and positioning device, including a support component, a first limiting component, a second limiting component, a first moving positioning component, a second moving positioning component, a first detection component, and a second detection component. The first detection component detects whether a workpiece to be tested is placed on the support component. The first limiting component and the first moving positioning component, and the second limiting component and the second moving positioning component, can clamp the workpiece to be tested in opposite directions, accurately positioning it to the required testing position. The second detection component detects whether the workpiece to be tested is properly clamped.

Furthermore, the suction cup fixation effectively reduces wear on the workpiece and minimizes testing failures caused by positioning deviations during the positioning process, thus improving testing efficiency.

Description

Technical Field

[0001] This disclosure relates to the field of clamping tooling technology, and in particular to a clamping and positioning device. Background Technology

[0002] With the advancement of technology, smart devices have gradually become necessities in people's lives. While pursuing performance, people are also placing higher demands on the appearance of smart devices, making the detection of appearance defects increasingly important. Traditional appearance defect detection largely relies on manual labor, with inspectors searching for defects by eye, consuming significant manpower and resources. This method is inefficient and susceptible to interference from subjective judgment and eye fatigue, easily leading to false positives and missed detections. Current mainstream inspection methods mostly utilize machine vision, positioning the part to be inspected at a specific location and using machine vision equipment to photograph it for defect detection. Therefore, higher requirements are placed on the positioning device for the part to be inspected. However, existing clamping and positioning devices suffer from poor automation and low positioning efficiency. After the part to be inspected is moved to the inspection position, it is prone to slight movement and displacement deviation, thus affecting the inspection effect and efficiency.

[0046] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0047] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0048] The structure of the clamping and positioning device in this embodiment is as follows: Figure 1 and Figure 2As shown, it includes a support component 1, a first limiting component 2, a second limiting component 3, a first moving positioning component 4, a second moving positioning component 5, a first detection component 6, and a second detection component 7. The support component 1 supports the workpiece to be tested and has multiple suction cups 11 capable of adsorbing and fixing the workpiece. In this embodiment, the suction cups 11 are preferably vacuum suction cups commonly used in the field, with air extraction holes on their surfaces. When the workpiece to be tested is placed on the vacuum suction cup, the air between the workpiece and the vacuum suction cup is extracted through the air extraction holes, so that the workpiece is adsorbed and fixed to the vacuum suction cup. Furthermore, the suction cup surface of the vacuum suction cup is mostly made of soft material, which can effectively prevent wear between the workpiece and the vacuum suction cup. The first limiting component 2 and the second limiting component 3 are both used to abut and limit the workpiece to be tested. The first limiting component 2 and the second limiting component 3 are located circumferentially on the support component 1, and the first limiting component 2 and the second limiting component 3 are not arranged opposite each other. Figure 1 As shown, in this embodiment, the first limiting component 2 and the second limiting component 3 are arranged perpendicularly. The first limiting component 2 is arranged along the length direction of the part to be tested, and the second limiting component 3 is arranged along the width direction of the part to be tested. The first limiting component 2 and the second limiting component 3 do not need to be arranged opposite each other. The positions of the first limiting component 2 and the second limiting component 3 include, but are not limited to, the positions shown in the attached figures of this embodiment, and can be selected as appropriate. In this embodiment, they are preferably arranged in the length and width directions of the part to be tested. The first moving positioning component 4 and the second moving positioning component 5 can respectively move and cooperate with the first limiting component 2 and the second limiting component 3. The first moving positioning component 4 can move towards the first limiting component 2, and the second moving positioning component 5 can move towards the second limiting component 3, so that the first moving positioning component 4 and the first limiting component 2, and the second moving positioning component 5 and the second limiting component 3, can clamp the workpiece to be tested in opposite directions. The four circumferential sides of the workpiece to be tested are respectively limited by the first limiting component 2, the second limiting component 3, the first moving positioning component 4, and the second moving positioning component 5, so that the workpiece to be tested can be accurately limited at the detection position, achieving precise limiting of the workpiece to be tested. The first detection component 6 is used to detect whether the workpiece to be tested is placed on the support component 1. When the first detection component 6 detects that the workpiece to be tested is placed on the support component 1, the first moving positioning component 4 and the second moving positioning component 5 begin to move and push the workpiece to be tested, so as to push the workpiece to be tested to the detection position. The second detection component 7 is used to detect whether the workpiece to be inspected is clamped in place. When the second detection component 7 detects that the workpiece to be inspected is clamped in place, the first moving positioning component 4 and the second moving positioning component 5 are reset and retracted. The suction cup component 11 is activated and adsorbs and fixes the workpiece to be inspected, so as to fix the workpiece to be inspected in the inspection position to complete the subsequent defect inspection. This prevents the workpiece to be inspected from moving when the first moving positioning component 4 and the second moving positioning component 5 are reset and retracted, which would cause the position to change and reduce the occurrence of inspection failures due to positioning deviation.

[0049] The clamping and positioning device of this embodiment has a compact overall structure and a high degree of automation. The first detection component 6 is used to detect whether a workpiece to be tested is placed on the support component 1. Through the movable first moving positioning component 4 and the second moving positioning component 5, the first limiting component 2 and the first moving positioning component 4, and the second limiting component 3 and the second moving positioning component 5 can achieve opposing clamping of the workpiece to be tested, thereby achieving circumferential limitation of the workpiece to be tested and accurately limiting the workpiece to the testing position. The second detection component 7 is used to detect whether the workpiece to be tested is clamped in place. After the workpiece to be tested is clamped in place, the suction cup component 11 is activated to adsorb and fix the workpiece to be tested, and the first moving positioning component 4 and the second moving positioning component 5 are reset and retracted, which can effectively prevent the workpiece to be tested from moving and changing position. Moreover, the adsorption and fixation of the workpiece to be tested by the suction cup component 11 can effectively reduce the wear of the workpiece to be tested. The clamping and positioning device of this embodiment can effectively improve the positioning accuracy and positioning efficiency of the workpiece to be tested, and can effectively reduce the occurrence of detection failures caused by positioning deviations during the positioning process, which is conducive to improving the detection efficiency.

[0050] Furthermore, such as Figure 1 As shown, the support component 1 in this embodiment includes a base 12 and a support 13, with the support 13 fixedly mounted on the base 12. Optionally, the support 13 can be fixedly mounted on the base 12 via four support columns. A first limiting component 2 and a second limiting component 3 are disposed around the base 12, and a first moving positioning component 4 and a second moving positioning component 5 are slidably connected to the base 12. The support 13 is used to support the component to be tested, and the suction cup component 11 is disposed on the support 13. More specifically, a support step 132 can also be provided on the support 13. The top surface of the support step 132 is planar, and multiple mounting slots for accommodating the suction cup component 11 are provided on the support step 132, so that the top surface of the suction cup component 11 is nearly flush with the top surface of the support step 132, ensuring that the component to be tested placed on the support step 132 is always in a horizontal state, ensuring the horizontality of the component to be tested, and preventing inaccurate testing due to horizontality errors.

[0051] Furthermore, such as Figure 2 As shown, the first moving positioning component 4 in this embodiment includes a first driving device 41 and a first moving plate group 42. The first driving device 41 is mounted on the base 12 and has a first moving output end 411. The first driving device 41 can be a telescopic motor. The first moving plate group 42 is connected to the first moving output end 411. When the first driving device 41 is started, it can drive the first moving plate group 42 to move towards the first limiting component 2 so that the first moving plate group 42 can abut against the workpiece to be tested, thereby realizing the opposing clamping between the first moving positioning component 4 and the first limiting component 2.

[0052] Furthermore, such as Figure 3As shown, the first moving positioning component 4 in this embodiment also includes a first slide rail 43, which is disposed on the base 12. The first moving plate group 42 is slidably connected to the first slide rail 43 to achieve stable movement of the first moving plate group 42.

[0053] Furthermore, such as Figure 3 As shown, in conjunction with reference Figure 2 The first movable plate assembly 42 includes a first slide block 421, a first movable plate 422, and a first locking member 423. A first movable output end 411 is connected to the first slide block 421, and the first slide block 421 is slidably connected to a first slide rail 43. A first protruding rail 4211 is provided on the first slide block 4211, and the first movable plate 422 is slidably connected to the first protruding rail 4211. The first movable plate 422 has multiple first mounting holes 4221, and the first locking member 423 can pass through the first mounting holes 4221 and be screwed onto the first slide block 421 to fix the first movable plate 422 onto the first slide block 421. It is understood that the position of the first movable plate 422 in this embodiment is adjustable. The position of the first movable plate 422 can be adjusted as needed according to actual usage to adapt to different sizes of test pieces, improving the overall versatility of the device. In use, first remove the first locking member 423 from the first mounting hole 4221, and manually push the first moving plate 422 inward or outward to move it to a suitable position. Then, screw the first locking member 423 into the first mounting hole 4221. In this embodiment, the position of the first mounting hole 4221 is directly opposite to the position of the first convex rail 4211, and the first convex rail 4211 also has a corresponding threaded hole. After the first locking member 423 passes through the first mounting hole 4221, it is screwed into the threaded hole on the first convex rail 4211 to fix the first moving plate 422 on the first moving plate 422. In addition, other methods can be used to install and fix the first moving plate 422, including but not limited to the methods shown in the accompanying drawings of this embodiment.

[0054] Furthermore, such as Figure 4 As shown, the first moving positioning component 4 also includes a first elastic element 44 and a first elastic element support 45. The first elastic element support 45 is mounted on the base 12. One end of the first elastic element 44 is connected to the first slide block 421, and the other end is connected to the first elastic element support 45. The first elastic element 44 is in a compressed state. It can be understood that the first elastic element 44 in this embodiment is always in a compressed state. The first elastic element 44 always provides an outward pushing force to the first slide block 421. When the object to be detected is pushed to the detection position, and the first moving positioning component 4 and the second moving positioning component 5 need to be reset and retracted, the first elastic element 44 can push the first slide block 421 outward to assist the first slide block 421 in moving outward and resetting, so that the first slide block 421 is reset to the initial position under the elastic force of the first driving device 41 and the first elastic element 44.

[0055] Furthermore, such as Figure 4 As shown, in conjunction with reference Figure 2 The first movable positioning component 4 also includes a first fastener 46 and a first fastening nut. The base 12 is provided with a first sliding groove 121. The first elastic element support 45 is slidably connected to the first sliding groove 121. One end of the first elastic element support 45 has a first positioning post 451. The other end of the first elastic element 44 is sleeved on the first positioning post 451. The first elastic element support 45 is provided with a first strip hole 452. The first sliding groove 121 is provided with a first sliding groove hole. The first fastener 46 passes through the first strip hole 452 and the first sliding groove hole and is screwed to the first fastening nut to fix the first elastic element support 45 in the first sliding groove 121. In this embodiment, the first elastic element 44 is specifically installed on the first elastic element support 45. One end of the first elastic element 44 is connected to the first slide block 421, and the other end is sleeved on the first positioning post 451. The first elastic element support 45 provides an installation point for the first elastic element 44, and its position is adjustable. The position of the first elastic element support 45 can be adjusted according to the actual situation, thereby adjusting the elastic resistance of the first elastic element 44. For example, moving the first elastic element support 45 away from the first limiting component 2 increases the compression of the first elastic element 44 and strengthens its elastic resistance; moving the first elastic element support 45 closer to the first limiting component 2 relatively weakens the compression of the first elastic element 44 and weakens its elastic resistance. The position of the first elastic element support 45 can be adjusted according to the actual situation. The first elastic element support 45 is fixed in the first slide groove 121 by the first fastener 46. The first slide groove 121 has a first slide groove hole, which can be a strip hole. The first fastener 46 is a bolt. After passing through the first strip hole 452 and the first slide groove hole, the first fastener 46 is screwed to the first fastening nut to fix the elastic element support 45.

[0056] Furthermore, such as Figure 1 As shown, the first limiting component 2 in this embodiment includes a first limiting seat 21 and a first limiting block 22. The first limiting seat 21 is fixedly disposed on the base 12, and the first limiting block 22 is fixedly disposed on the first limiting seat 21. The first limiting block 22 can abut against the part to be tested. In this embodiment, the first limiting component 2 is fixedly installed on the base 12, and its position cannot be moved or adjusted. In other embodiments, the first limiting component 2 can also be set to a movable form, including but not limited to the situation shown in the attached drawings of this embodiment.

[0057] Furthermore, such as Figure 2As shown, the second limiting component 3 in this embodiment includes a movable base 31 and a second limiting base 32. The movable base 31 is movably mounted on the base 12. In this embodiment, the movable base 31 is a commonly used slide cylinder. The second limiting base 32 is mounted on the movable base 31 and can abut against the workpiece to be tested. The position of the second limiting component 3 in this embodiment is adjustable to adapt to the positioning of workpieces of different shapes and sizes.

[0058] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, the second detection component 7 in this embodiment includes a first position sensor group 71 and a second sensor group 72. The first position sensor group 71 is used to detect whether the first moving positioning component 4 has moved into place, and the second sensor group 72 is used to detect whether the second sensor group 72 has moved into place. The second detection component 7 in this embodiment detects that the workpiece to be tested is clamped in place by detecting whether the first moving positioning component 4 and the second moving positioning component 5 have moved into place using the first position sensor group 71 and the second sensor group 72, respectively. The first position sensor group 71 includes a first slotted photoelectric switch receiver 711 and a first slotted photoelectric switch baffle 712. The second sensor group 72 includes a second slotted photoelectric switch receiver 721 and a second slotted photoelectric switch baffle 722. The first slotted photoelectric switch receiver 711 and the second slotted photoelectric switch receiver 721 are fixedly mounted on the base 12, and the first slotted photoelectric switch baffle 712 and the second slotted photoelectric switch baffle 722 are correspondingly mounted on the first moving positioning component 4 and the second moving positioning component 5. In this embodiment, both the first position sensor group 71 and the second sensor group 72 use slotted photoelectric sensor groups. The first slotted photoelectric switch baffle 712 and the second slotted photoelectric switch baffle 722 are bent into an L-shape and respectively installed on the first slide 421 and the second slide 521. The first slotted photoelectric switch receiver 711 and the second slotted photoelectric switch receiver 721 are installed at specific positions on the base 12. When the first moving positioning component 4 and the second moving positioning component 5 move and clamp into place, the first slotted photoelectric switch baffle 712 on the first slide 421 and the second slotted photoelectric switch baffle 722 on the second slide 521 will move accordingly and extend into the first slotted photoelectric switch receiver 711 and the second slotted photoelectric switch receiver 721. The specific installation position of the first slotted photoelectric switch receiver 711 and the second slotted photoelectric switch receiver 721 is related to the position to be detected. The first slotted photoelectric switch receiver 711 and the second slotted photoelectric switch receiver 721 are commonly used sensors in the field. Their specific structure and principle refer to the existing technology in the field. This embodiment will not elaborate on them.

[0059] In addition, other position sensors or pressure sensors can be selected for the first position sensor group 71 and the second sensor group 72. Once the pressure values ​​fed back by the first position sensor group 71 and the second sensor group 72 are stable within a certain range, it is determined that the workpiece to be tested has been clamped and limited, depending on the actual situation.

[0060] Furthermore, such as Figure 2 As shown, the first detection component 6 in this embodiment includes a fiber optic sensor 61 and a fiber optic support 62. The fiber optic support 62 is fixedly mounted on the base 12, and the fiber optic sensor 61 is mounted on the fiber optic support 62. When the object to be detected is placed on the support 13, the fiber optic sensor 61 will sense the object. The fiber optic sensor 61 is a commonly used sensor in the field, and its specific implementation principle can be found in existing technology, which will not be elaborated in this embodiment. In addition, laser transceivers, etc., can also be used, including but not limited to using the fiber optic sensor 61.

[0061] Optionally, such as Figure 1 As shown, the support component 1 in this embodiment also includes a mounting base 123. The mounting base 123 is used to fix the base 12 in a designated position. The mounting base 123 in this embodiment is provided with three threaded assembly holes. Two of the threaded assembly holes are used for screwing the mounting base 123 and the base 12 together. The remaining threaded assembly holes are used for fixing the mounting base 123 to other equipment or a table, so that the clamping and positioning device can be fixedly installed in the designated position as a whole.

[0062] Optionally, in order to improve the support stability of the support 13 for the test piece, two support columns 131 are provided on the support 13. The support columns 131 are used to support the test piece. The height of the support columns 131 is flush with the height of the support steps 132, so that the test piece is subjected to uniform force and the support is stable.
