Part Detection Device, Carrying Fixture and Clamping and Positioning Mechanism

Abstract

The present invention relates to a part detection device, a loading fixture and a clamping and positioning mechanism. By applying an external force, the clamping space can be opened first, and then the part to be tested is placed on the stage. As the external force is withdrawn, the first jaw and the second jaw can approach each other under the action of the elastic member, so that the clamping space automatically retracts and clamps the part to be tested. Moreover, when the part to be tested is clamped in the clamping space, the first jaw abuts against the limiting member under the action of the elastic member. That is to say, the first jaw can be used as the positioning reference for the part to be tested, so as to realize rapid positioning of the part to be tested. Thus, after the part to be tested is placed on the stage, the clamping and positioning mechanism can automatically clamp and position the part to be tested, thereby significantly improving the positioning efficiency.

[0053] Please refer to Figure 1 , the present invention provides a part detection device 10 and a carrier fixture 100. In addition, the present invention also provides a clamping and positioning mechanism 130. Among them, the part detection device 10 includes a carrier fixture 100, a detection mechanism 200 and a translation drive mechanism 300.

[0054] The carrier fixture 100 is used to position and carry a part to be tested 20 as Figure 8 shown. The part to be tested 20 can be a housing part such as a mobile phone housing. The carrier fixture 100 includes a clamping and positioning mechanism 130, and positions the part to be tested 20 through the clamping and positioning mechanism 130.

[0055] The detection mechanism 200 is located on one side of the carrier fixture 100, and the detection mechanism 200 is used to scan the surface of the part to be tested 20 carried on the carrier fixture 100. The detection mechanism 200 can be a laser scanner or a CCD scanning module.

[0056] 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 loading fixture 100 is provided on the translation drive mechanism 300, and the translation drive mechanism 300 can drive the loading fixture 100 to slide along a preset direction. The translation drive mechanism 300 can drive the part 20 to be measured on the loading fixture 100 from the loading position to the scanning area of the detection mechanism 200. Moreover, when there are multiple parts 20 to be measured on the loading fixture 100, the translation drive mechanism 300 can drive the multiple parts 20 to pass through the scanning area of the detection mechanism 200 in sequence, so as to realize scanning one by one.

[0057] It should be noted that in other embodiments, the number of the detection mechanisms 200 is the same as the number of the parts 20 to be measured carried on the loading fixture 100. At this time, the detection mechanisms 200 can be arranged in one-to-one correspondence with the parts 20 to be measured, and the translation drive mechanism 300 can be omitted.

[0058] Please refer to Figure 2 and Figure 3 , the loading fixture 100 in the preferred embodiment of the present invention includes a mounting plate 110, a carrier table 120, and a clamping and positioning mechanism 130. Among them:

[0059] The mounting plate 110 plays a supporting role and is generally a metal plate structure. Among them, the loading fixture 100 is installed on the translation drive mechanism 300 through the mounting plate 110.

[0060] The carrier table 120 is provided on the mounting plate 110 and is used to carry the part 20 to be measured. The carrier table 120 can be a metal block structure and has strong rigidity. The part 20 to be measured is carried on the bearing surface of the carrier table. When the mounting plate 110 is placed on a horizontal plane, the bearing surface is parallel to the horizontal plane.

[0061] In order to prevent the part 20 to be measured from slipping off the carrier table 120, specifically in this embodiment, a first suction cup 121 is provided on the bearing surface of the carrier table 120. The first suction cup 121 can be a vacuum suction cup communicated with a vacuum pump and realizes adsorption by pumping vacuum. The first suction cup 121 can adsorb the surface of the part 20 to be measured on the bearing surface of the carrier table 120, so as to reliably fix the part 20 to be measured on the carrier table 120.

[0062] In order to be able to detect the sides of multiple parts to be measured 20 at one time, thereby improving the detection efficiency. Specifically, in this embodiment, a plurality of spaced-apart carriers 120 are provided on the mounting plate 110. Each carrier 120 can carry one part to be measured 20. More specifically, the plurality of carriers 120 are spaced apart under the drive of the translation drive mechanism 300. When performing detection, the translation drive mechanism 300 can drive the mounting plate 110 to slide, so that the plurality of carriers 120 sequentially pass through the scanning area of the detection mechanism 200, thereby realizing the individual detection of the surfaces of the multiple parts to be measured 20.

[0063] Please refer to Figure 4 and Figure 5 , the clamping and positioning mechanism 130 includes a support base 131, a clamping member 132, a limiting member 133 and an elastic member 134.

[0064] The support base 131 supports the clamping and positioning mechanism 130 and is generally plate-shaped. The support base 131 is provided on the mounting plate 110, thereby mounting the entire clamping and positioning mechanism 130 on the mounting plate 110.

[0065] The clamping member 132 is provided on the support base 131 and is used to clamp the part to be measured 20 and position the part to be measured 20 at a preset position on the carrier 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 carriers 120 one by one. Each clamping member 132 can clamp and position the part to be measured 20 carried on the corresponding carrier 120.

[0066] The clamping member 132 includes a first clamping jaw 1321 and a second clamping jaw 1322 that are oppositely arranged on the support base 131. Among them, a clamping space for clamping the part to be measured 20 is formed between the first clamping jaw 1321 and the second clamping jaw 1322. The clamping space can be opened and retracted. When the clamping space is opened, it is convenient to place the part to be measured 20 on the carrier 120, and when the clamping space is retracted, the part to be measured 20 on the carrier 120 can be clamped and positioned. Specifically, the first clamping jaw 1321 and the second clamping jaw 1322 can be arranged on the mounting plate 131 by sliding or rotating, and the two can be brought closer or farther away by rotating or sliding, thereby realizing the opening or retraction of the clamping space.

[0067] The limiting member 133 is provided on the support base 131 and is located on the side of the first clamping jaw 1321 facing the second clamping jaw 1322. The limiting member 133 can be a block-shaped, column-shaped or convex structure welded, screwed or clamped to the mounting plate 131.

[0068] The elastic member 134 can be a spring, a spring sheet, or an elastic cord. The elastic member 134 provides an elastic force to the first jaw 1321 and the second jaw 1322, so that the first jaw 1321 and the second jaw 1322 have a tendency to clamp closer. That is to say, on the premise of no external force, the first jaw 1321 and the second jaw 1322 will automatically clamp under the action of the elastic force of the elastic member 134.

[0069] 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 support base 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 support base 131, and the other end abuts against the side of the second jaw 1322 facing away from the first jaw 1321.

[0070] The first compression spring 1341 provides an elastic force to the first jaw 1321 pointing to the second jaw 1322, while the second compression spring 1342 provides an elastic force to the second jaw 1322 pointing to 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 have a tendency to approach each other.

[0071] More specifically, a second limit block 138 can be provided on the side of the first jaw 1321 facing away from the second jaw 1322, and a spring abutment seat 139 is provided on the side of the second jaw 1322 facing away from the first jaw 1321. Both the second limit block 138 and the spring abutment seat 139 are fixed to the support base 131. Among them, the first compression spring 1341 is clamped between the second limit block 138 and the first jaw 1321; the second compression spring 1342 is clamped between the spring abutment seat 139 and the second jaw 1322.

[0072] Moreover, when the part to be measured 20 is clamped in the clamping space, the first jaw 1321 abuts against the limiting member 133 under the action of the elastic member 134. Since the position of the limiting member 133 on the support base 131 remains unchanged, the position of the first jaw 1321 is fixed every time the part to be measured 20 is clamped. Therefore, the first jaw 1321 can be used as a positioning reference for the part to be measured 20, so as to realize rapid positioning of the part to be measured 20.

[0073] It should be noted that the first jaw 1321 and the second jaw 1322 are not specific, and are only used to distinguish the two jaws that make up the clamping member 132. In this embodiment, the left jaw shown in the figure is the first jaw 1321, and the right jaw is the second jaw 1322; in other embodiments, the right jaw can also be used as the first jaw 1321, and the left jaw can be used as the second jaw 1322.

[0074] Further, 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 may have a greater 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.

[0075] When positioning the part 20 to be measured on the loading fixture 100, the first jaw 1321 and the second jaw 1322 can be separated by an external force first to open the clamping space; then the part 20 to be measured is placed on the stage 120. Next, when the external force is withdrawn, the first jaw 1321 and the second jaw 1322 can approach each other under the action of the elastic member 134, so that the clamping space automatically retracts and clamps the part 20 to be measured until the first jaw 1321 abuts against the limiting member 133. Thus, it can be seen that after the part 20 to be measured is placed on the stage 120, the clamping and positioning mechanism 130 can automatically clamp and position the part 20 to be measured, thereby significantly improving the positioning efficiency.

[0076] In this embodiment, the position of the limiting member 133 on the support base 131 is adjustable. Specifically, the limiting member 133 can be installed on the support base 131 by means of thread fastening, clamping, etc. When the position of the limiting member 133 changes, the size of the clamping space when the clamping member 132 clamps the part 20 to be measured will also change. Therefore, the clamping and positioning mechanism 130 can be applied to the clamping and positioning of various different types of parts, improving the compatibility of the loading fixture 100.

[0077] 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.

[0078] 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 each other under the action of the elastic member 134, so that the clamping space automatically retracts and clamps the part 20 to be measured.

[0079] Further, in this embodiment, the clamping drive assembly 135 includes a first transmission plate 1351, a first clamping drive member 1352, a second transmission plate 1353 and a second clamping drive member 1354. Among them:

[0080] The first transmission plate 1351 is slidably arranged on the support seat 131, and the first clamping jaw 1321 is fixed to the first transmission plate 1351. The first transmission plate 1351 is strip-shaped. In this embodiment, there are multiple clamping members 132, so multiple first clamping jaws 1321 are arranged at intervals on the first transmission plate 1351. The second transmission plate 1353 is slidably arranged on the support seat 131, and the second clamping jaw 1322 is fixed to the second transmission plate 1353. The second transmission plate 1353 is also strip-shaped and is consistent with the extending direction of the first transmission plate 1351. Similarly, multiple second clamping jaws 1322 are arranged at intervals on the second transmission plate 1354.

[0081] Both the first transmission plate 1351 and the second transmission plate 1353 can be installed on the support seat 131 by means of a guide rail-slider combination. Moreover, when the first transmission plate 1351 and the second transmission plate 1353 slide along the support seat 131, they can drive multiple first clamping jaws 1321 to approach or move away from the corresponding second clamping jaws 1322. Therefore, multiple clamping members 132 can be simultaneously retracted or expanded under the drive of the first transmission plate 1351 and the second transmission plate 1354, thereby further improving the operation efficiency.

[0082] In addition, the positions of multiple first clamping jaws 1321 on the first transmission plate 1351 are adjustable, and the positions of multiple second clamping jaws 1322 on the second transmission plate 1353 are adjustable. Specifically, multiple strip-shaped holes (not shown in the figure) extending along the length direction can be formed on the first transmission plate 1351, and each first clamping jaw 1321 can be installed on the first transmission plate 1351 by cooperating with the corresponding strip-shaped hole through a threaded fastener. The second clamping jaw 1322 can be installed on the second transmission plate 1353 in the same way to achieve adjustable position. In this way, the relative positions between the first clamping jaw 1321 and the second clamping jaw 1322 can be adjusted according to requirements, so as to accommodate the assembly error of the carrier fixture 100.

[0083] The first clamping driving member 1352 and the second clamping driving member 1354 can be cylinders or linear motors. Among them, the first clamping driving member 1352 abuts against the first transmission plate 1351 to drive the first transmission plate 1351 to slide in a direction away from the second clamping jaw 1322; the second clamping driving member 1354 abuts against the second transmission plate 1353 to drive the second transmission plate 1353 to slide in a direction away from the first clamping jaw 1321. That is to say, the first clamping driving member 1352 is not fixedly connected to the first transmission plate 1351, and the second clamping driving member 1354 is not fixedly connected to the second transmission plate 1353. Therefore, when the first clamping jaw 1321 and the second clamping jaw 1322 approach each other, the moving distance between the two can be automatically controlled by the elastic member 134, and the size of the clamping space can float within a certain range.

[0084] The dimensions of the part 20 to be measured have errors and will fluctuate within a certain range. When the dimensions of the clamping space of the clamping member 132 can also float within a certain range, the clamping and positioning mechanism 130 can meet the clamping requirements of the working conditions where the dimensions of the part 10 to be measured have errors.

[0085] Specifically, in this embodiment, the clamping drive assembly 135 further includes a first connecting plate 1355 and a second connecting plate 1356. The structures of the first connecting plate 1355 and the second connecting plate 1356 can be the same, and both can be metal plate-like structures. The first connecting plate 1355 is fixedly connected to the first transmission plate 1351, and the first clamping drive member 1352 abuts against the first connecting plate 1355; the second connecting plate 1356 is fixedly connected to the second transmission plate 1353, and the second clamping drive member 1354 abuts against the second connecting plate 1356.

[0086] That is to say, the first clamping drive member 1352 and the second clamping drive member 1354 respectively abut against the first transmission plate 1351 and the second transmission plate 1353 through the first connecting plate 1355 and the second connecting plate 1356. In this way, the layout of the first clamping drive member 1352 and the second clamping drive member 1354 can be more conveniently carried out.

[0087] In this embodiment, the clamping and positioning mechanism 130 further includes a fixed seat 136 and a lifting drive member 137. Among them, the lifting drive member 137 is arranged on the fixed seat 136, the support seat 131 is slidably installed on the fixed seat 136, and the drive end of the lifting drive member 137 is in transmission connection with the support seat 131 to drive the support seat 131 to lift relative to the fixed seat 136.

[0088] The fixed seat 136 can be a vertical plate structure erected on the mounting plate 110, and the support seat 131 is installed on the mounting plate 110 through the fixed seat 136. The support seat 131 can be connected to the fixed seat 136 through a linear guide slider structure. The lifting drive member 137 can be a linear motor or a cylinder. When placing the part 20 to be measured on the carrier 120, the lifting drive member 137 can drive the support seat 131 to descend until the clamping member 132 reaches below the carrier 120 along with the support seat 131. At this time, the bearing surface of the carrier 120 protrudes from the clamping member 132, so as to avoid interference of the clamping member 132 with the operation of placing the part 20 to be measured. When it is necessary to clamp and position the part 20 to be measured, the lifting drive member 137 drives the support seat 131 to rise until the clamping member 132 is substantially flush with the part 20 to be measured on the carrier 120.

[0089] Such as Figure 8As shown, the part 20 to be measured generally includes a flexible cable 21, and the flexible cable 21 generally extends from the middle of the part 20 to be measured to outside the surface range of the part 20 to be measured. Therefore, the flexible cable 21 will partially block the surface of the part 20 to be measured, thereby interfering with the detection of the surface of the part 20 to be measured.

[0090] To solve the above problems. Please refer to again Figure 1 and Figure 2 Specifically in this embodiment, the carrier fixture 100 further includes a folding mechanism 140 provided on the mounting plate 110. The folding mechanism 140 can grab the flexible cable 21 and drive the flexible cable 21 to flip relative to the part 20 to be measured.

[0091] The folding mechanism 140 can grab the flexible cable 21 by means of clamping or sucking, and by flipping the flexible cable 21, the flexible cable 21 is opened from the surface of the part 20 to be measured. Usually, the folding mechanism 140 needs to drive the flexible cable 21 to flip 90 degrees, so that the projection of the flexible cable 21 on the surface of the part 20 to be measured is minimized.

[0092] The process of the part detection device 10 detecting the part 20 to be measured is roughly as follows: The translation drive mechanism 300 drives the carrier fixture 100 to move into the scanning range of the detection mechanism 200, and the detection mechanism 200 collects the surface information of the part 20 to be measured; then, the folding mechanism 140 acts to fold the flexible cable 21; then, the translation drive mechanism 300 drives the carrier fixture 100 to move into the scanning range of the detection mechanism 200 again. At this time, since the flexible cable 21 is folded, the originally blocked area on the surface of the part 20 to be measured is exposed, so that the detection mechanism 200 can conveniently scan the entire area of the part 20 to be measured.

[0093] Furthermore, please refer to together Figure 6 and Figure 7 In this embodiment, the folding mechanism 140 includes a horizontal drive assembly 141, a vertical drive assembly 142, a rotation drive assembly 143 and a second suction cup 144.

[0094] The horizontal drive assembly 141 is provided on the mounting plate 110 and is spaced from the clamping and positioning mechanism 130 in the first direction. The horizontal drive assembly 141 can be a motor lead screw pair mechanism, an electric cylinder or a cylinder. The vertical drive assembly 142 is provided at the drive end of the horizontal drive assembly 141, and the horizontal drive assembly 141 can drive the vertical drive assembly 142 to move along the first direction. The vertical drive assembly 142 can also be a motor lead screw pair mechanism, an electric cylinder or a cylinder horizontal drive assembly 141. The folding mechanism 140 further includes a support plate 145, the support plate 145 is fixed to the drive end of the horizontal drive assembly 141, and the vertical drive assembly 142 is fixed to the support plate 145.

[0095] The rotation drive assembly 143 is provided at the drive end of the vertical drive assembly 142, and the vertical drive assembly 142 can drive the rotation drive assembly 143 to move in a second direction perpendicular to the first direction. Specifically, the first direction refers to Figure 1 the vertical direction shown, and the second direction refers to the direction perpendicular to the paper surface of the drawing. The rotation end of the rotation drive assembly 143 is provided with a second suction cup 144 that can suck the flexible cable 21. The second suction cup 144 can be a vacuum suction cup and can suck the flexible cable 21.

[0096] More specifically, the rotation drive assembly 143 includes a motor 1431, a pulley 1432, and a rotating shaft 1433. The motor 1431 drives the rotating shaft 1433 to rotate through the pulley 1432, and the second suction cup 144 is provided on the rotating shaft 1433. As the rotating shaft 1433 rotates, the second suction cup 144 will drive the sucked flexible cable 21 to achieve flipping.

[0097] When the folding mechanism 140 operates, the horizontal drive assembly 141 first drives the vertical drive assembly 142 to approach the clamping and positioning mechanism 130 in the first direction until the second suction cup 144 is located above the carrier 120. Then, the vertical drive assembly 142 drives the rotation drive assembly 143 to descend until the second suction cup 144 abuts against and adsorbs the flexible cable 21 of the part 20 to be tested on the carrier 120. Finally, the rotation drive assembly 143 drives the second suction cup 144 to rotate, realizing the folding of the flexible cable 21.

[0098] When the folding mechanism 140 does not perform the folding action, the horizontal drive assembly 141 can drive the vertical drive assembly 142, the rotation drive assembly 143, and the second suction cup 144 away from above the carrier 120 to form an avoidance position, thereby facilitating the placement of the part 20 to be tested on the carrier 120.

[0099] Furthermore, please refer to Figure 2 and Figure 3 again. In this embodiment, the carrier fixture 100 further includes a supporting assembly 150. Among them, the supporting assembly 150 includes a support 151 and a support block 152. Wherein:

[0100] The support 151 is fixedly arranged relative to the carrier 120. Specifically, the support 151 can be directly fixedly connected to the carrier 120 or can be fixedly arranged on the mounting plate 110. The support block 152 is provided on the support 151 and is slidable in a direction perpendicular to the bearing surface of the carrier 120. Moreover, there is an elastic support between the support block 152 and the support 151. The support block 152 is located at the edge of the carrier 120 and can support the flexible cable 21 of the part 20 to be tested located on the carrier 120.

[0101] The supporting block 152 can be slidably mounted to the support 151 through a guide rail slider. Moreover, the supporting block 152 can be a metal block with good rigidity and a flat surface. In the initial state, the surface of the supporting block 152 can be substantially flush with the bearing surface of the carrier 120. In this way, the wiring harness 21 of the part 20 to be tested on the carrier 120 can be better supported. When the folding mechanism 140 grabs the wiring harness 21, the supporting block 152 can provide support, making it more convenient to grab.

[0102] The supporting assembly 150 further includes a buffer spring 153, which is clamped between the support 151 and the supporting block 152. Moreover, the elastic force direction of the buffer spring 153 is consistent with the sliding direction of the supporting block 152, thereby realizing elastic support between the supporting block 152 and the support 151. Since the elastic support exists between the supporting block 152 and the support 151, the supporting block 152 can float relative to the support 151 under the action of an external force. Therefore, when the folding mechanism 140 grabs the wiring harness 21 and comes into contact with the supporting block 152, the supporting block 152 can play a buffering role through floating, thus avoiding hard contact and damage between the part for grabbing the wiring harness 21 of the folding mechanism 140, such as between the second suction cup 144 and the supporting block 152.

[0103] For the above-mentioned part detection device 10, the carrying fixture 100 and the clamping and positioning mechanism 130, the clamping space can be opened first by an external force, and then the part 20 to be tested is placed on the carrier 120. As the external force is withdrawn, 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 and clamps the part 20 to be tested. Moreover, when the part 20 to be tested is clamped in the clamping space, the first clamping jaw 1321 abuts against the limiting member 133 under the action of the elastic member 134. That is to say, the first clamping jaw 1321 can be used as the positioning reference for the part 20 to be tested, thereby realizing rapid positioning of the part 20 to be tested. It can be seen that after the part 20 to be tested is placed on the carrier 120, the clamping and positioning mechanism 130 can automatically clamp and position the part 20 to be tested, thus significantly improving the positioning efficiency.

[0104] 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 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.

[0105] The above-described embodiments merely represent several implementation manners of the present invention. 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 fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
