Abstract

The present invention relates to a part detection device and a carrying fixture. The part to be tested can be first placed on the stage, and then clamped and positioned by the clamping member, so as to position the part to be tested at a preset position on the stage. After positioning is completed, the clamping member is loosened. Then, driven by the lifting mechanism, the clamping member can rise relative to the stage. During the process of lifting the clamping member, the wire harness hanging on the edge of the part to be tested can be lifted. When the clamping member protrudes above the upper surface of the part to be tested, the wire harness is also lifted above the surface of the part to be tested. At this time, the wire harness will not block the side surface of the part to be tested. Therefore, the above-mentioned part detection device and carrying fixture facilitate the detection of the side surface of the part.

Technical Field

[0001] The present invention relates to the technical field of mechanical automation, and in particular to a parts detection device and a bearing fixture. Background Art

[0002] During the process of processing and testing parts, the parts need to be positioned at the preset position of the workbench. For some special parts, such as mobile phone shells, there are flexible and long cables on them. Therefore, after the parts are positioned, the cables will droop under the action of gravity and block the side walls of the parts, making it inconvenient to detect the side of the parts.

[0016] In one embodiment, the elastic force provided by the first compression spring (1341) is greater than the elastic force provided by the second compression spring (1342).

[0044] Please refer to Figure 1 , the present invention provides a part detection device 10 and a carrier fixture 100. Among them, the part detection device 10 includes a carrier fixture 100, a detection mechanism 200 and a translation drive mechanism 300.

[0045] The carrier fixture 100 is used to position and carry the part to be measured 20. As Figure 5 shown, the part to be measured 20 targeted by the above-mentioned part detection device 10 generally includes a flexible cable 21, and the flexible cable 21 extends beyond the surface range of the part to be measured 20.

[0046] The detection mechanism 200 is located on one side of the carrier fixture 100 and is spaced from the carrier fixture 100 in the first direction. The detection mechanism 200 includes a detector 210, and the detector 210 is used to scan the side of the part to be measured 20 carried on the carrier fixture 100. The detector 210 can be a laser scanner or a CCD scanning module.

[0047] The translation drive mechanism 300 can achieve feeding in a second direction perpendicular to the first direction. As Figure 1 shown, in this embodiment, the first direction refers to the vertical direction and the second direction is the horizontal direction. The translation drive mechanism 300 can be a motor with a guide rail slider mechanism, a motor screw thread pair mechanism or a cylinder with a guide rail slider mechanism. The carrier fixture 100 is arranged on the translation drive mechanism 300 and can move along the second direction under the drive of the translation drive mechanism 300. The translation drive mechanism 300 can drive the part to be measured 20 on the carrier fixture 100 to be transferred from the loading position to the scanning area of the detector 210. Moreover, when there are multiple parts to be measured 20 carried on the carrier fixture 100, the translation drive mechanism 300 can drive the multiple parts to be measured 20 to pass through the scanning area of the detector 210 in sequence, so as to achieve scanning one by one.

[0048] It should be pointed out that in other embodiments, the number of detectors 210 is the same as the number of parts to be measured 20 carried on the carrier fixture 100. At this time, the detectors 210 can be arranged in one-to-one correspondence with the parts to be measured 20, and the translation drive mechanism 300 can be omitted.

[0049] Please refer to Figure 2 and Figure 3 . In a preferred embodiment of the present invention, the carrier fixture 100 includes a fixed seat 110, a stage 120, a clamping and positioning mechanism 130, and a lifting mechanism 140.

[0050] The fixed seat 110 plays a supporting role and is generally a metal plate-like structure. Among them, the carrier fixture 100 is installed through the fixed seat 110 and the translation driving mechanism 300.

[0051] The stage 120 is disposed on the fixed seat 110 and is used to carry the part 20 to be measured. The stage 120 can be a metal block structure with strong rigidity. The part 20 to be measured is carried on the bearing surface of the stage. When the fixed seat 110 is placed on a horizontal plane, this bearing surface is parallel to the horizontal plane.

[0052] In order to prevent the part 20 to be measured from slipping off the stage 120, specifically in this embodiment, a suction cup 121 is provided on the bearing surface of the stage 120. The suction cup 121 can be a vacuum suction cup communicated with a vacuum pump and realizes adsorption by pumping vacuum. The suction cup 121 can adsorb on the surface of the part 20 to be measured on the bearing surface of the stage 120, thereby reliably fixing the part 20 to be measured on the stage 120.

[0053] Specifically in this embodiment, the carrier fixture 100 further includes a turntable 150 disposed on the fixed seat 110. The stage 120 is disposed at the rotating end of the turntable 150, and the rotation axis of the turntable 150 is perpendicular to the bearing surface of the stage 120. The turntable 150 can be driven by a motor, thereby driving the stage 120 and the part 20 to be measured on the stage 120 to rotate. Therefore, it is convenient for the detector 210 to scan the side surfaces around the part 20 to be measured without removing the part 20 to be measured from the stage 120.

[0054] Furthermore, in this embodiment, the detection mechanism 200 further includes a longitudinal driving assembly 220 and a mounting block 230. The mounting block 230 is rotatably disposed at the driving end of the longitudinal driving assembly 220, the detector 210 is fixed on the mounting block 230, and the longitudinal driving assembly 220 can drive the mounting block 230 to move in the first direction.

[0055] The longitudinal driving assembly 220 can be a cylinder, a linear motor or a motor screw pair mechanism. The mounting block 230 can be a metal block. An arc-shaped groove (not shown in the figure) is formed on the mounting block 230, and the mounting block 230 is installed through the arc-shaped groove at the driving end of the longitudinal driving assembly 220, so that the mounting block 230 can rotate relative to the driving end of the longitudinal driving assembly 220.

[0056] When the longitudinal driving assembly 220 operates, it can drive the detector 210 to move in the first direction, thereby adjusting the distance between the detector 210 and the stage 120. After the turntable 150 drives the stage 120 to rotate, through the adjustment of the longitudinal driving assembly 220, the part 20 to be measured on the stage 120 can always be located within the optimal scanning range of the detector 210. At the same time, by rotating the mounting block 230, the scanning angle of the detector 210 can also be adjusted, so that the detector 210 is at the optimal scanning angle.

[0057] In order to be able to detect the sides of multiple parts 20 to be measured at one time, thereby improving the detection efficiency. Specifically, in this embodiment, a plurality of spaced-apart stages 120 are provided on the fixed base 110. Each stage 120 can carry a part 20 to be measured. More specifically, the plurality of stages 120 are spaced apart in the second direction. During detection, the translation driving mechanism 300 can drive the fixed base 110 to slide in the second direction, so that the plurality of stages 120 sequentially pass through the scanning area of the detector 210, thereby realizing the individual detection of the sides of the multiple parts 20 to be measured.

[0058] Furthermore, in this embodiment, the detection mechanism 200 includes a plurality of detectors 210 spaced apart in the second direction. Therefore, the detection mechanism 200 can simultaneously scan the parts 20 to be measured on the plurality of stages 120, thereby further improving the detection efficiency.

[0059] The number of detectors 210 included in the detection mechanism 200 can be equal to the number of stages 120 or less than the number of stages 120. As Figure 1 shown, six stages 120 and three detectors 210 are provided. Among them, each detector 210 is responsible for scanning the parts 20 to be measured on two stages 120. When the translation driving mechanism 300 drives the fixed base 110 to move to the designated position, the three detectors 210 can respectively scan the parts 20 to be measured on the first, third, and fifth stages 120 from left to right. After the scanning is completed, the translation driving mechanism 300 will drive the fixed base 110 to move a length equal to the distance between two stages 120, and the three detectors 210 can respectively scan the parts 20 to be measured on the remaining second, fourth, and sixth stages 120.

[0060] The clamping and positioning mechanism 130 includes a clamping member 132, and the clamping member 132 can clamp and position the part 20 to be measured at a preset position on the stage 120. Specifically, in this embodiment, the clamping and positioning mechanism 130 includes a plurality of clamping members 132, and the plurality of clamping members 132 correspond to the plurality of stages 120 one by one. Each clamping member 132 can clamp and position the part 20 to be measured carried on the corresponding stage 120.

[0061] The clamping member 132 is formed with a clamping space that can be opened and retracted. The clamping space is generally arranged circumferentially around the carrier 120. When the clamping space is opened, it is convenient to place the part 20 to be measured on the carrier 120. When the clamping space is retracted, the part 20 to be measured on the carrier 120 can be clamped and positioned. Since the cable 21 extends beyond the surface range of the part 20 to be measured, when the clamping member 132 clamps the part 20 to be measured, the cable 21 can be supported on the clamping member 132.

[0062] The lifting mechanism 140 is in driving connection with the clamping member 132 and can drive the clamping member 132 to lift in a direction perpendicular to the bearing surface of the carrier (120). Specifically, the lifting mechanism 140 can drive the mounting plate 131 to lift and lower in the Figure 2 vertical direction as shown until the clamping member 132 is lifted above the carrier 120.

[0063] Specifically in this embodiment, the clamping and positioning mechanism (130) further includes a mounting plate 131, and the clamping member 132 is arranged on the mounting plate 131. Further, the mounting plate 131 is slidable in a direction perpendicular to the bearing surface of the carrier 120. Specifically, two vertical plates 111 are fixedly spaced on the fixed seat 110, and both ends of the mounting plate 131 are respectively arranged on the two vertical plates 111 through a linear guide rail slider structure. Moreover, the linear guide rail extends in a direction perpendicular to the bearing surface of the carrier 120, that is, the vertical direction.

[0064] The lifting mechanism 140 is in driving connection with the mounting plate 131 and drives the mounting plate 131 to lift and lower relative to the fixed seat 110, thereby driving the clamping member 132 to lift. Obviously, the clamping member 132 can also be lifted relative to the carrier 120 in a rotational or flipping manner under the drive of the lifting mechanism 140.

[0065] After the clamping and positioning mechanism 130 completes the positioning of the part 20 to be measured, the clamping member 132 can be loosened. Then, driven by the lifting mechanism 140, the clamping member 132 rises relative to the fixed seat 110. During the lifting process of the clamping member 132, the cable 21 hanging on the edge of the part 20 to be measured can be lifted. Moreover, when the clamping member 132 is lifted to protrude above the upper surface of the part 20 to be measured, the cable 21 is also lifted above the surface of the part 20 to be measured. At this time, the cable 21 will not block the side surface of the part 20 to be measured, thus facilitating the detector 210 to detect the side surface of the part.

[0066] After the positioning of the part 20 to be measured, the part 20 to be measured can be fixed on the stage 120 under the action of the suction cup 121. At this time, the clamping member 132 releases the part 20 to be measured, so that the clamping member 132 will not interfere with the positioned part 20 to be measured during the lifting process. It can be seen that while the clamping and positioning mechanism 130 positions the part 20 to be measured, it can also lift the cable 21, so there is no need to additionally set up components for lifting the cable 21. Therefore, the structure of the carrier fixture 100 is simplified.

[0067] In addition, the lifting mechanism 140 can not only drive the mounting plate 131 to rise, but also drive the mounting plate 131 to descend. That is, the lifting mechanism 140 can drive the clamping member 132 to descend below the stage 120. When the clamping member 132 descends with the mounting plate 131 to a position lower than the bearing surface of the stage 120, the bearing surface of the stage 120 protrudes from the clamping member 132, thereby preventing the clamping member 132 from interfering with the operation of placing the part 20 to be measured on the stage 120.

[0068] In this embodiment, the lifting mechanism 140 includes a first lifting driving member 141, a lifting connection plate 142 and a second lifting driving member 143. The first lifting driving member 141 is fixed to the fixed seat 110; the lifting connection plate 142 is fixedly connected to the driving end of the first lifting driving member 141; the second lifting driving member 143 is fixed to the lifting connection plate 142, and the driving end of the second lifting driving member 143 is in transmission connection with the mounting plate 131.

[0069] The first lifting driving member 141 and the second lifting driving member 143 can be cylinders. When the first lifting driving member 141 acts, it can drive the lifting connection plate 142, the second lifting driving member 143 and the mounting plate 131 to move upward as a whole by a certain height, so as to drive the clamping member 132 to move to be roughly flush with the workpiece on the stage 120 for clamping and positioning. Then, when the second lifting driving member 143 acts, it can drive the mounting plate 131 to continue to rise by a certain height, so that the clamping member 132 lifts the cable 21 of the part 20 to be measured upward.

[0070] The clamping member 132 can clamp and position the part 20 to be measured in a variety of ways. For example, in this embodiment, the clamping and positioning mechanism 130 further includes a limiting member 133 provided on the mounting plate 131. The limiting member 133 can be a block-shaped, column-shaped or protruding structure welded, screwed or clamped to the mounting plate 131.

[0071] Furthermore, the clamping member 132 includes a first clamping jaw 1321 and a second clamping jaw 1322 oppositely arranged on the mounting plate 131. The limiting member 133 is located on the side of the first clamping jaw 1321 facing the second clamping jaw 1322, and when the first clamping jaw 1321 and the second clamping jaw 1322 clamp the part 20 to be measured, the first clamping jaw 1321 abuts against the limiting member 133.

[0072] A clamping space is formed between the first clamping jaw 1321 and the second clamping jaw 1322. The first clamping jaw 1321 and the second clamping jaw 1322 can be arranged on the mounting plate 131 by means of sliding or rotating, and by rotating or sliding, the two can be made to approach or move away from each other, so as to realize the opening or retraction of the clamping space. Moreover, protruding parts or bent parts and other structures can be arranged at the ends of the first clamping jaw 1321 and the second clamping jaw 1322 for lifting the wire harness 21.

[0073] After the part 20 to be measured is placed on the carrier 120, the first clamping jaw 1321 and the second clamping jaw 1322 approach each other to clamp the part 20 to be measured in the clamping space. At this time, the first clamping jaw 1321 abuts against the limiting member 133. That is to say, every time the part 20 to be measured is clamped, the position of the first clamping jaw 1321 is fixed. Therefore, the first clamping jaw 1321 can be used as a positioning reference for the part 20 to be measured, so as to realize the rapid positioning of the part 20 to be measured.

[0074] In this embodiment, the position of the limiting member 133 on the mounting plate 131 is adjustable. Specifically, the limiting member 133 can be installed on the mounting plate 131 by means of threaded fastening, clamping, etc. When the position of the limiting member 133 changes, it will cause the size of the clamping space to change when the clamping member 132 clamps the part 20 to be measured. Therefore, the clamping and positioning mechanism 130 can be applied to the clamping and positioning of parts of a variety of different models, improving the compatibility of the loading fixture 100.

[0075] In this embodiment, the clamping and positioning mechanism 130 further includes an elastic member 134. The elastic member 134 provides an elastic force to the first clamping jaw 1321 and the second clamping jaw 1322, so that the first clamping jaw 1321 and the second clamping jaw 1322 have a tendency to approach each other, and when the clamping member 132 clamps the part 20 to be measured, the first clamping jaw 1321 abuts against the limiting member 133 under the action of the elastic member 134.

[0076] The elastic member 134 can be a spring, a spring piece or an elastic rope. After the clamping member 132 is opened and the part 20 to be measured is placed, the first clamping jaw 1321 and the second clamping jaw 1322 can approach each other under the action of the elastic member 134, so that the clamping space automatically retracts until the part 20 to be measured is clamped, thereby realizing the automatic clamping and positioning of the part 20 to be measured, and significantly improving the positioning efficiency.

[0077] Specifically, in this embodiment, the elastic member 134 includes a first compression spring 1341 and a second compression spring 1342. One end of the first compression spring 1341 abuts against the mounting plate 131, and the other end abuts against the side of the first jaw 1321 facing away from the second jaw 1322; one end of the second compression spring 1342 abuts against the mounting plate 131, and the other end abuts against the side of the second jaw 1322 facing away from the first jaw 1321.

[0078] The first compression spring 1341 provides an elastic force to the first jaw 1321 pointing towards the second jaw 1322, while the second compression spring 1342 provides an elastic force to the second jaw 1322 pointing towards the first jaw 1321. Therefore, under the action of the first compression spring 1341 and the second compression spring 1342, the first jaw 1321 and the second jaw 1322 tend to approach each other.

[0079] More specifically, a second limiting block 136 can be provided on the side of the first jaw 1321 facing away from the second jaw 1322, and a third limiting block 137 and a fourth limiting block 138 are provided on both sides of the second jaw 1322. The first compression spring 1341 is clamped between the second limiting block 136 and the first jaw 1321. The third limiting block 137 and the fourth limiting block 138 can limit the movement range of the second jaw 1322. Moreover, the fourth limiting block 138 is located on the side of the second jaw 1322 facing away from the first jaw 1321, and the second compression spring 1342 is clamped between the fourth limiting block 138 and the second jaw 1322.

[0080] Furthermore, in this embodiment, the elastic force provided by the first compression spring 1341 is greater than the elastic force provided by the second compression spring 1342. The first compression spring 1341 can have a larger elastic coefficient or pre-compression amount compared to the second compression spring 1342, so as to generate an elastic force greater than that of the second compression spring 1342. In this way, it can be ensured that when the part 20 to be measured is clamped, the first jaw 1321 abuts against the limiting member 133.

[0081] In this embodiment, the clamping and positioning mechanism 130 further includes a clamping drive assembly 135, and the clamping drive assembly 135 abuts against the first jaw 1321 and the second jaw 1322 to drive the first jaw 1321 and the second jaw 1322 to move away from each other.

[0082] The clamping drive assembly 135 is not fixedly connected to the first jaw 1321 and the second jaw 1322, and is only used to drive the first jaw 1321 and the second jaw 1322 to move away from each other. When the action of the clamping drive assembly 135 is withdrawn, the first jaw 1321 and the second jaw 1322 will approach and clamp the part 20 to be measured under the action of the elastic member 134. The clamping drive assembly 135 will not interfere with the movement process of the first jaw 1321 and the second jaw 1322.

[0083] Please refer to Figure 4 as well. In this embodiment, the clamping drive assembly 135 includes a first drive plate 1351, a first clamping drive member 1353, a second drive plate 1354, and a second clamping drive member 1356. Among them:

[0084] The first drive plate 1351 is slidably disposed on the mounting plate 131, and the first jaw 1321 is fixed to the first drive plate 1351. The first drive plate 1351 is in a strip shape. In this embodiment, there are multiple clamping members 132, so multiple first jaws 1321 are spaced apart on the first drive plate 1351. The second drive plate 1354 is slidably disposed on the mounting plate 131, and the second jaw 1322 is fixed to the second drive plate 1354. The second drive plate 1354 is also in a strip shape and is consistent with the extending direction of the first drive plate 1351. Similarly, multiple second jaws 1322 are spaced apart on the second drive plate 1354.

[0085] Both the first drive plate 1351 and the second drive plate 1354 can be mounted on the mounting plate 131 by means of a guide rail-slider combination. Moreover, when the first drive plate 1351 and the second drive plate 1354 slide along the mounting plate 131, they can drive multiple first jaws 1321 to approach or move away from the corresponding second jaws 1322. Therefore, multiple clamping members 132 can be simultaneously retracted or expanded under the drive of the first drive plate 1351 and the second drive plate 1354, thereby further improving the operation efficiency.

[0086] In addition, the positions of multiple first jaws 1321 on the first drive plate 1351 are adjustable, and the positions of multiple second jaws 1322 on the second drive plate 1354 are adjustable. Specifically, multiple strip-shaped holes (not shown in the figure) extending along the length direction can be formed on the first drive plate 1351, and each first jaw 1321 can be mounted on the first drive plate 1351 by cooperating with the corresponding strip-shaped hole through a threaded fastener. The second jaw 1322 can be mounted on the second drive plate 1354 in the same way to achieve adjustable position. In this way, the relative positions between the first jaws 1321 and the second jaws 1322 can be adjusted as needed, so as to accommodate the assembly error of the carrier fixture 100.

[0087] The first clamping driving member 1353 and the second clamping driving member 1356 can be air cylinders or linear motors. Among them, the first clamping driving member 1353 abuts against the first transmission plate 1351 to drive the first transmission plate 1351 to slide in a direction away from the second jaw 1322; the second clamping driving member 1356 abuts against the second transmission plate 1354 to drive the second transmission plate 1354 to slide in a direction away from the first jaw 1321. That is to say, the first clamping driving member 1353 is not fixedly connected to the first transmission plate 1351, and the second clamping driving member 1356 is not fixedly connected to the second transmission plate 1354. Therefore, when the first jaw 1321 and the second jaw 1322 approach each other, the elastic member 134 can automatically control the moving distance between the two, and the size of the clamping space can float within a certain range.

[0088] The dimensions of the part to be measured 20 have errors and will fluctuate within a certain range. When the size of the clamping space of the clamping member 132 can also float within a certain range, it can enable the clamping and positioning mechanism 130 to meet the clamping requirements of the working conditions where the dimensions of the part to be measured 10 have errors.

[0089] Specifically, in this embodiment, the clamping driving assembly 135 further includes a first connecting plate 1352 and a second connecting plate 1355. The structures of the first connecting plate 1352 and the second connecting plate 1355 can be the same, and both can be metal plate-like structures. The first connecting plate 1352 is fixedly connected to the first transmission plate 1351, and the first clamping driving member 1353 abuts against the first connecting plate 1352; the second connecting plate 1355 is fixedly connected to the second transmission plate 1354, and the second clamping driving member 1356 abuts against the second connecting plate 1355.

[0090] That is to say, the first clamping driving member 1353 and the second clamping driving member 1356 abut against the first transmission plate 1351 and the second transmission plate 1354 respectively through the first connecting plate 1352 and the second connecting plate 1355. In this way, it is possible to more conveniently layout the first clamping driving member 1353 and the second clamping driving member 1356.

[0091] The following combines the attached Figures 1 to 5 , and briefly describes the working process of the part detection device 10:

[0092] First, place the part to be measured 20 on the stage 120 by manual positioning, and the lifting mechanism 140 drives the clamping member 132 to rise to be roughly flush with the stage 120. Then, the clamping and positioning mechanism 130 clamps and positions the part to be measured 20.

[0093] After positioning is completed, the clamping member 132 releases the part 20 to be measured, and the part 20 to be measured is fixed on the surface of the stage 120 by the suction cup 121. Then, driven by the lifting mechanism 140, the clamping member 132 continues to rise relative to the stage 120 and lifts the wiring harness 21 hanging on the edge of the part 20 to be measured.

[0094] When the clamping member 132 lifts the wiring harness 21 to the surface of the part 20 to be measured, the wiring harness 21 will not block the side surface of the part 20 to be measured. At this time, the detector 210 can detect the side surface of the part. Therefore, the above-mentioned part detection device 10 and the carrying jig 100 facilitate the detection of the side surface of the part.

[0095] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0096] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
