Description

Technical Field

[0001] This invention relates to the field of dimensional detection technology, and in particular to an intelligent detection device for the dimensions of a metal housing cavity. Background Technology

[0002] Metal casings typically have intricate cavity structures, making efficient and accurate measurement of these cavity dimensions a crucial step in the production process. Currently, the measurement of metal casing cavity dimensions primarily relies on the following methods.

[0003] Manual sampling and measurement using measuring tools: Traditional methods employ general-purpose measuring tools such as calipers, micrometers, and plug gauges, or specialized inspection tools, for manual contact measurement. This method is inefficient, difficult to achieve full inspection, and the measurement results are highly dependent on the operator's skill and condition, resulting in subjective errors. It cannot meet the efficiency and consistency requirements of large-scale automated production. Coordinate measuring machine (CMM) inspection: As a high-precision general-purpose measuring device, the CMM can accurately measure cavity dimensions. However, its measurement speed is slow, typically only suitable for laboratory sampling or new product development stages. Deploying it on the production line for online full inspection would severely slow down the production cycle, and the equipment investment and maintenance costs would be high.

[0004] While some automated dimensional inspection equipment has emerged on the market, it generally suffers from the following problems when dealing with metal housing cavities: poor clamping adaptability (traditional automated fixtures are mostly rigid structures, making it difficult to accommodate metal housings of different sizes and specifications; manual adjustment or replacement of fixtures is usually required during model changes, resulting in long production line downtime and insufficient flexible production capacity); poor coordination between inspection and loading / unloading (the inspection mechanism, loading mechanism, and unloading mechanism are often designed independently, leading to insufficient smooth flow of workpieces between different workstations, resulting in waiting time and affecting overall inspection efficiency); and low functional integration (existing equipment typically only has inspection functions; post-processing steps such as sorting and classifying qualified and unqualified products require additional manual labor or equipment, failing to form a complete closed loop from automatic loading, inspection, sorting to automatic unloading). Summary of the Invention

[0005] To address the aforementioned technical problems, this invention discloses an intelligent detection device capable of efficiently and accurately automatically detecting the cavity dimensions of various specifications of metal shells, and capable of automatically loading and unloading materials and automatically sorting qualified and unqualified products. The technical solution adopted by this invention is as follows: an intelligent detection device for the cavity dimensions of metal shells, comprising an intermediate frame and a detection mechanism for detecting the cavity dimensions of metal shells. The intermediate frame is provided with an infeeding mechanism for feeding the metal shells to be detected and an outfeeding mechanism for sending out the metal shells after detection. The detection mechanism includes a main rotating disk rotatably mounted on an intermediate frame. Four clamping modules are equally spaced on the main rotating disk. Each clamping module includes a clamping plate, and the clamping plates of the clamping modules located on the main rotating disk are fixedly installed with the main rotating disk.

[0006] Furthermore, the detection mechanism also includes a bottom motor fixedly installed below the intermediate frame. The bottom motor drives the main rotating disk to rotate via a lower transmission belt. Four release columns are fixedly installed on the main rotating disk, and the release columns are located next to the clamping module on the main rotating disk.

[0007] Furthermore, the detection mechanism also includes a detection frame fixedly installed on the intermediate frame, a lifting cylinder fixedly installed on the detection frame, a lifting block fixedly installed on the output end of the lifting cylinder, a detection motor fixedly installed on the lifting block, a detection column fixedly installed on the output end of the detection motor, and an intelligent sensor fixedly installed on the detection column.

[0008] Furthermore, the clamping module also includes a rotating stud rotatably mounted on the clamping plate, the rotating stud forming a threaded drive with the clamping plate, a bottom lifting block rotatably mounted below the rotating stud, a release plate rotatably mounted on the bottom lifting block, the release plate penetrating the side of the clamping plate, a lower pressure plate rotatably mounted above the rotating stud, and a rotating clamping plate fixedly mounted on the rotating stud, the rotating clamping plate being provided with four oblique sliding grooves.

[0009] Furthermore, the clamping module also includes a side clamping plate slidably mounted on the clamping disk, a side guide post fixedly mounted on the side clamping plate, the side guide post being slidably mounted on the clamping disk, a movable frame fixedly mounted on the side clamping plate, a clamping guide post fixedly mounted on the movable frame, and the clamping guide post sliding within the inclined groove.

[0010] Furthermore, the clamping module also includes two inner slopes respectively disposed at both ends of the inner side of the movable frame. The inner slopes include an inner recessed portion and an outer recessed portion, with a protrusion formed between the inner and outer recessed portions. The clamping plate is provided with two telescopic columns respectively corresponding to the two inner slopes. A side arc head is fixedly installed at the end of the telescopic column. The outer surface of the side arc head is an arc surface. A retaining spring is disposed between the side arc head and the clamping plate. The side arc head fits against the inner slope, and the retaining spring is in a compressed state.

[0011] The bottom motor drives the main rotating disk to rotate via the lower transmission belt. The main rotating disk drives the clamping module and the metal shell to rotate 90 degrees each time. When the clamping module, carrying the metal shell, reaches the testing frame, the lifting cylinder extends, driving the lifting block to descend, allowing the smart sensor to enter the inner cavity of the metal shell. The testing motor drives the testing column and the smart sensor to rotate. The smart sensor measures the inner cavity size of the metal shell, and in conjunction with the retraction of the lifting cylinder, it drives the smart sensor to rise, enabling the smart sensor to perform a comprehensive test of the inner cavity size of the metal shell.

[0012] The intelligent sensor integrates a high-precision ranging module. When the intelligent sensor rotates and rises inside the cavity, it continuously emits energy towards the inner wall of the cavity and receives reflected signals. By measuring the time difference or phase difference between emission and reception, the real-time distance from the center of the intelligent sensor to the inner wall is calculated.

[0013] When the tablet is pressed down, it causes the rotating stud and bottom lifting block to descend. The bottom lifting block causes the release plate to rotate relative to the fulcrum. With the threaded engagement between the clamping plate and the rotating stud, the rotation of the rotating stud causes the rotating clamping plate to rotate. The rotating clamping plate drives the clamping guide post, the movable frame, and the side clamping plate to move inward through the inclined slide. When the movable frame moves inward, the side arc head moves along the inner side slope. The side arc head first moves along the concave part on the inner side slope to the convex point on the inner side slope. Then, after the side arc head passes the convex point, the retaining spring rebounds, and the side arc head moves to the concave part on the outer side of the inner side slope. The side clamping plate clamps the metal shell, with the side arc head located in the recessed part outside the inner slope. The retaining spring is always in a compressed state. The recessed part of the inner slope has a certain range, allowing the side arc head of the retaining spring to be held in a recessed part of the inner slope. When the retaining spring is in the recessed part, the recessed part can restrict movement relative to the recessed part, thus playing a limiting role and preventing loosening during clamping, thereby achieving stable clamping. This allows the side clamping plate to clamp the metal shell within a certain size range.

[0014] When the outer end of the release plate is pushed away from the lower pressure plate, the release plate drives the bottom lifting block, the rotating stud and the lower pressure plate to rise. The rotating stud drives the rotating clamping plate to rotate. The rotating clamping plate drives the clamping guide post, the movable frame and the side clamping plate to move outward through the inclined slide. At this time, the side arc head passes over the convex point of the side inner slope from the concave part on the outside of the side inner slope to the concave part on the inside of the side inner slope, so that the side clamping plate opens. At this time, the side clamping plate no longer clamps the metal shell.

[0015] Furthermore, the feeding mechanism includes a feeding frame fixedly installed on the intermediate frame, a connecting frame fixedly installed on the feeding frame, a traverse motor fixedly installed on the connecting frame, a horizontal lead screw rotatably installed inside the connecting frame, the horizontal lead screw being fixedly installed with the motor shaft of the traverse motor, a traverse frame slidably installed on the connecting frame, the traverse frame and the horizontal lead screw forming a threaded transmission, a lifting motor fixedly installed on the traverse frame, a lifting lead screw rotatably installed on the traverse frame, the lifting lead screw being fixedly installed with the motor shaft of the lifting motor, a pick-and-place block slidably installed on the traverse frame, the pick-and-place block forming a threaded transmission with the lifting lead screw, a clamping module provided on the pick-and-place block, the clamping plate of the clamping module on the pick-and-place block being fixedly installed with the pick-and-place block, and a central clamping column fixedly installed on the lower pressure plate of the clamping module located on the pick-and-place block.

[0016] Furthermore, the feeding mechanism also includes a baffle plate fixedly installed on the feeding frame.

[0017] In operation, the metal casing to be tested is placed on the conveyor belt, which transports it. When the conveyor belt reaches the blocking plate, the blocking plate intercepts the metal casing. Then, the traverse motor drives the horizontal lead screw to rotate, which moves the traverse frame above the metal casing. Next, the lifting motor rotates, driving the lifting lead screw to rotate. The lifting lead screw lowers the pick-and-place block and clamping plate, bringing the side clamping plates to the outside of the metal casing. The clamping plate continues to descend, and when the central clamping post contacts the metal casing, the clamping plate continues to descend, applying an upward reaction force through the metal casing to the central clamping post. This presses down the lower pressure plate, rotating stud, and rotating clamping plate, causing the four side clamping plates to move inward, clamping the upper part of the metal casing. Finally, the lifting motor drives the pick-and-place block and clamping plate... The platen rises, lifting the metal casing from the conveyor belt. Then, the traversing motor moves the traversing frame above the clamping module on the main rotating plate. The pick-and-place block then descends, placing the bottom of the metal casing on the lower pressure plate of the clamping module on the main rotating plate. The pick-and-place block continues to descend, pressing the bottom of the metal casing against the lower pressure plate of the clamping module on the main rotating plate. At this point, the four side clamping plates move inward, clamping the lower half of the metal casing. Simultaneously, the release column contacts the release plate of the clamping module on the pick-and-place block, causing the release plate to rotate and the four side clamping plates to move outward. This releases the clamping module on the pick-and-place block from the metal casing, transferring it to the clamping module on the main rotating plate. The clamping module on the pick-and-place block remains open. The pick-and-place block then rises back above the conveyor belt.

[0018] Furthermore, the delivery mechanism includes an output frame and a defective frame fixedly installed on the intermediate frame. A conveyor motor is fixedly installed on the output frame, and a conveyor belt is provided on the output frame. The conveyor motor drives the conveyor belt to rotate through a transmission belt. A side conveyor belt is provided on the defective frame, and a take-up module is provided on both the output frame and the defective frame.

[0019] Furthermore, the retrieval module includes a retrieval frame. The retrieval frame of the retrieval module located on the output frame is fixedly installed on the output frame, and the retrieval frame of the retrieval module located on the defective frame is fixedly installed on the defective frame. Release frames are fixedly installed on the output frame and the defective frame, respectively. A side-moving motor is fixedly installed on the retrieval frame, and a side-moving screw is rotatably installed on the retrieval frame. The side-moving screw is fixedly installed on the motor shaft of the side-moving motor. A side-moving frame is slidably installed on the retrieval frame, and the side-moving frame and the side-moving screw form a threaded transmission. An upper and lower motor is fixedly installed on the side-moving frame, and upper and lower screws are rotatably installed on the side-moving frame. The upper and lower screws are fixedly installed on the motor shaft of the upper and lower motors. Upper and lower blocks are slidably installed on the side-moving frame, and the upper and lower blocks form a threaded transmission with the upper and lower screws. A clamping module is provided on the upper and lower blocks. A release rod is fixedly installed on the clamping plate of the clamping module on the upper and lower blocks, and a central column is fixedly installed on the lower pressure plate of the clamping module on the upper and lower blocks.

[0020] If the metal casing passes the inspection, the take-up module on the output rack will activate when the metal casing moves to the output rack along with the main rotating disk. If the metal casing fails the inspection, the take-up module on the non-conforming rack will activate when the metal casing moves to the non-conforming rack along with the main rotating disk.

[0021] When the qualified metal casing moves to the output frame, the side-moving motor drives the side-moving lead screw to rotate. The lead screw moves the side-moving frame to above the metal casing on the main rotating plate. Subsequently, the upper and lower motors drive the upper and lower lead screws to rotate. The upper and lower lead screws drive the upper and lower blocks and the clamping plate to descend. When the release rod contacts the release plate of the clamping module on the main rotating plate, it drives the release plate to rotate, thereby causing the side clamping plate on the main rotating plate to no longer clamp the lower half of the metal casing. At the same time, the central column contacts the metal casing. Under the reaction force of the metal casing, the clamping modules on the upper and lower blocks... The side clamping plate clamps the upper part of the metal shell. Then, the upper and lower motors drive the upper and lower blocks and the metal shell to rise. Then, the side motor drives the upper and lower blocks to the top of the side conveyor belt. Then, the upper and lower motors drive the upper and lower blocks to fall. When the release plate of the clamping module on the upper and lower blocks contacts the release frame, the release frame causes the release plate of the clamping module on the upper and lower blocks to rotate, so that the side clamping plate no longer clamps the metal shell. The metal shell falls onto the conveyor belt and is sent out by the conveyor belt. At this time, the clamping module on the upper and lower blocks remains in the open state and then returns to the initial position.

[0022] When the defective metal casing moves to the defective rack, the side-moving motor drives the side-moving screw to rotate. The side-moving screw moves the side-moving rack to above the metal casing on the main rotating plate. Subsequently, the upper and lower motors drive the upper and lower screws to rotate. The upper and lower screws move the upper and lower blocks and the clamping plate downwards. When the release rod contacts the release plate of the clamping module on the main rotating plate, it drives the release plate to rotate, thus causing the side clamping plate on the main rotating plate to no longer clamp the lower half of the metal casing. At the same time, the central column contacts the metal casing. Under the reaction force of the metal casing, the clamping modules on the upper and lower blocks... The side clamping plate clamps the upper part of the metal shell. Then, the upper and lower motors drive the upper and lower blocks and the metal shell to rise. Then, the side motor drives the upper and lower blocks to the top of the side conveyor belt. Then, the upper and lower motors drive the upper and lower blocks to fall. When the release plate of the clamping module on the upper and lower blocks contacts the release frame, the release frame causes the release plate of the clamping module on the upper and lower blocks to rotate, so that the side clamping plate no longer clamps the metal shell. The metal shell falls onto the side conveyor belt and is sent out by the side conveyor belt. At this time, the clamping module on the upper and lower blocks remains in the open state and then returns to the initial position.

[0023] The beneficial effects of this invention compared with the prior art are: (1) By setting up an infeeding mechanism, a detection mechanism, and an outfeeding mechanism, and integrating two independent conveying channels for qualified and unqualified products, this invention realizes the fully automated operation of the metal shell from loading and detection to sorting and unloading. The main turntable separates the detection station from the loading and unloading station in space. Unqualified products are automatically removed by the take-up module on the unqualified rack and sent to the side conveyor belt, while qualified products are sent to the main conveyor belt by the take-up module on the output rack, realizing online automatic sorting and improving the overall cycle time and automation level of the production line; (2) The clamping module set up in this invention adopts a unique structural design and has adaptive clamping capability. When the central clamping column or the central column contacts the metal shell and is pressed down, the rotating stud drives the rotating clamping plate to rotate. Through the cooperation of the inclined slide and the clamping guide column, the four side clamping plates are driven to move inward synchronously. The cooperation structure of the inner slope and the side arc head allows the side clamping plates to be stably held in the clamping state under the action of the clamping spring. The concave part of the inner slope has a certain range, allowing the side clamping plates to adaptively clamp metal shells of different shapes and sizes within a certain stroke. This design does not require manual adjustment or replacement of the clamps, and can quickly adapt to various specifications of products, improving the versatility and flexible production capacity of the equipment and reducing the changeover time; (3) The detection mechanism set in this invention integrates a liftable and rotatable intelligent During detection, the lifting cylinder drives the intelligent sensor into the inner cavity of the metal shell, and the detection motor drives it to rotate at a constant speed. At the same time, the lifting cylinder retracts to make the sensor complete a spiral upward continuous scan in the cavity. The intelligent sensor integrates a high-precision ranging module, which continuously transmits detection medium and receives reflected signals to calculate the distance from the center of the sensor to the inner wall of the cavity in real time. Compared with the traditional fixed-point measurement, this dynamic scanning measurement method can obtain more comprehensive contour data of the inner wall of the cavity, effectively avoid the omission of local features, and improve the accuracy and reliability of the detection results; (4) The present invention sets up a connection structure in both the feeding mechanism and the feeding mechanism that is linked with the clamping module on the main rotating disk. Taking the feeding mechanism as an example, when the pick-and-place block places the metal shell onto the clamping module on the main rotating disk, on the one hand, the bottom of the metal shell presses down the lower pressure plate of the clamping module on the main rotating disk, causing its side clamping plate to clamp the lower half of the workpiece. On the other hand, the release column on the intermediate frame simultaneously lifts the release plate of the clamping module on the pick-and-place block, causing its side clamping plate to open automatically, completing the seamless handover of the workpiece. Similarly, when sending out, the pick-up module triggers the release plate of the clamping module on the main rotating disk through the release rod, realizing the release of the workpiece. This mechanical linkage handover does not require additional sensors or electrical control logic, has a compact structure, and is reliable in operation, ensuring the smoothness and positional accuracy of the workpiece transfer between different workstations.

Detailed Implementation

[0038] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0039] Example: Reference Figures 1-13 A smart detection device for the cavity size of a metal shell includes an intermediate frame 101 and a detection mechanism for detecting the cavity size of a metal shell 5. The intermediate frame 101 is provided with an infeed mechanism for feeding the metal shell 5 to be detected and an outfeed mechanism for feeding the metal shell 5 after detection out. The testing mechanism includes a main rotating disk 102 rotatably mounted on an intermediate frame 101. Four clamping modules are equally spaced on the main rotating disk 102. Each clamping module includes a clamping disk 201. The clamping disk 201 of the clamping module located on the main rotating disk 102 is fixedly installed on the main rotating disk 102.

[0040] like Figure 2 , Figure 3 As shown, the testing mechanism also includes a bottom motor 109 fixedly installed below the intermediate frame 101. The bottom motor 109 drives the main rotating disk 102 to rotate via the lower transmission belt 110. Four release columns 111 are fixedly installed on the main rotating disk 102, and the release columns 111 are located next to the clamping module on the main rotating disk 102.

[0041] like Figure 2 , Figure 3As shown, the testing mechanism also includes a testing frame 103 fixedly installed on the intermediate frame 101. A lifting cylinder 104 is fixedly installed on the testing frame 103. A lifting block 105 is fixedly installed on the output end of the lifting cylinder 104. A testing motor 106 is fixedly installed on the lifting block 105. A testing column 107 is fixedly installed on the output end of the testing motor 106. An intelligent sensor 108 is fixedly installed on the testing column 107.

[0042] like Figures 4-8 As shown, the clamping module also includes a rotating stud 207 rotatably mounted on the clamping disk 201. The rotating stud 207 and the clamping disk 201 form a threaded drive. A bottom lifting block 205 is rotatably mounted below the rotating stud 207. A release plate 204 is rotatably mounted on the bottom lifting block 205. The release plate 204 passes through the side of the clamping disk 201. A lower pressure plate 206 is rotatably mounted above the rotating stud 207. A rotating chuck 208 is fixedly mounted on the rotating stud 207. The rotating chuck 208 is provided with four inclined sliding grooves 209.

[0043] like Figures 4-8 As shown, the clamping module also includes a side clamping plate 202 slidably mounted on the clamping disk 201. A side guide post 203 is fixedly mounted on the side clamping plate 202. The side guide post 203 is slidably mounted on the clamping disk 201. A movable frame 211 is fixedly mounted on the side clamping plate 202. A clamping guide post 210 is fixedly mounted on the movable frame 211. The clamping guide post 210 slides in the inclined slide groove 209.

[0044] like Figures 4-8 As shown, the clamping module also includes two inner slopes 215 respectively disposed at both ends of the inner side of the movable frame 211. The inner slope 215 includes an inner recessed portion and an outer recessed portion, and a protrusion is formed between the inner recessed portion and the outer recessed portion. The clamping disk 201 is provided with two telescopic columns 212 respectively corresponding to the two inner slopes 215. A side arc head 214 is fixedly installed at the end of the telescopic column 212. The outer surface of the side arc head 214 is an arc surface. A retaining spring 213 is disposed between the side arc head 214 and the clamping disk 201. The side arc head 214 is in contact with the inner slope 215, and the retaining spring 213 is in a compressed state.

[0045] The bottom motor 109 drives the main rotating disk 102 to rotate via the lower transmission belt 110. The main rotating disk 102 drives the clamping module and the metal shell 5 to rotate 90 degrees each time. When the clamping module carries the metal shell 5 to the side of the detection frame 103, the lifting cylinder 104 extends, driving the lifting block 105 to descend, so that the intelligent sensor 108 enters the inner cavity of the metal shell 5. The detection motor 106 drives the detection column 107 and the intelligent sensor 108 to rotate. The intelligent sensor 108 measures the inner cavity size of the metal shell 5, and in conjunction with the retraction of the lifting cylinder 104, it drives the intelligent sensor 108 to rise, so that the intelligent sensor 108 can perform a comprehensive detection of the inner cavity size of the metal shell 5.

[0046] The intelligent sensor 108 integrates a high-precision ranging module. When the intelligent sensor 108 rotates and rises inside the cavity, it continuously emits a detection medium towards the inner wall of the cavity and receives reflected signals. By measuring the time difference or phase difference between the emission and reception, the real-time distance from the center of the intelligent sensor 108 to the inner wall is calculated.

[0047] When the pressing tablet 206 is pressed down, it causes the rotating stud 207 and the bottom lifting block 205 to descend. The bottom lifting block 205 causes the release plate 204 to rotate relative to the fulcrum. With the threaded engagement between the clamping plate 201 and the rotating stud 207, the rotating stud 207 rotates, causing the rotating clamping plate 208 to rotate. The rotating clamping plate 208 drives the clamping guide post 210, the movable frame 211, and the side clamping plate 202 to move inward through the inclined slide groove 209. When the movable frame 211 moves inward, the side arc head 214 moves along the inner side slope 215. The side arc head 214 first moves along the concave part inside the inner side slope 215 to the protrusion of the inner side slope 215, where the retaining spring 213 is continuously compressed. Then, after the side arc head 214 passes the protrusion, the retaining spring 213 rebounds, and the side arc head 214 moves to the outer side of the inner side slope 215. The recessed portion allows the side clamping plate 202 to clamp the metal shell 5. At this time, the side arc head 214 is located in the recessed portion outside the side inner slope 215. The retaining spring 213 is always in a compressed state. The recessed portion of the side inner slope 215 has a certain range, so that the side arc head 214 of the retaining spring 213 can be kept in a recessed portion of the side inner slope 215. When the retaining spring 213 is located in the recessed portion of the side inner slope 215, the recessed portion of the side inner slope 215 can restrict the movement of the telescopic column 212 relative to the side inner slope 215, thereby limiting the side clamping plate 202 and preventing the side clamping plate 202 from loosening during clamping. This ensures that the side clamping plate 202 maintains a stable clamping of the metal shell 5, and that the side clamping plate 202 can keep the metal shell 5 within a certain size range.

[0048] When the outer end of the release plate 204 is pushed away from the lower pressure plate 206, the release plate 204 drives the bottom lifting block 205, the rotating stud 207 and the lower pressure plate 206 to rise. The rotating stud 207 drives the rotating clamping plate 208 to rotate. The rotating clamping plate 208 drives the clamping guide post 210, the movable frame 211 and the side clamping plate 202 to move outward through the inclined slide groove 209. At this time, the side arc head 214 passes the protrusion of the side inner slope 215 from the recessed part on the outside of the side inner slope 215 to the recessed part on the inside of the side inner slope 215, so that the side clamping plate 202 opens. At this time, the side clamping plate 202 no longer clamps the metal shell 5.

[0049] like Figure 9 , Figure 10 As shown, the feeding mechanism includes a feeding frame 301 fixedly mounted on the intermediate frame 101, a connecting frame 303 fixedly mounted on the feeding frame 301, a traverse motor 302 fixedly mounted on the connecting frame 303, a horizontal lead screw 308 rotatably mounted inside the connecting frame 303, the horizontal lead screw 308 being fixedly mounted to the motor shaft of the traverse motor 302, a traverse frame 304 slidably mounted on the connecting frame 303, the traverse frame 304 and the horizontal lead screw 308 forming a threaded transmission, and a lifting motor 304 fixedly mounted on the traverse frame 304. 5. A lifting screw 306 is rotatably mounted on the transverse frame 304. The lifting screw 306 is fixedly mounted to the motor shaft of the lifting motor 305. A pick-and-place block 307 is slidably mounted on the transverse frame 304. The pick-and-place block 307 and the lifting screw 306 form a threaded transmission. A clamping module is provided on the pick-and-place block 307. The clamping plate 201 of the clamping module on the pick-and-place block 307 is fixedly mounted to the pick-and-place block 307. A central clamping column 310 is fixedly mounted on the lower pressure plate 206 of the clamping module located on the pick-and-place block 307.

[0050] like Figure 9 , Figure 10 As shown, the feeding mechanism also includes a baffle plate 309 fixedly installed on the feeding frame 301.

[0051] In use, the metal casing 5 to be tested is placed on the conveyor belt 405, which transports the metal casing 5. When the conveyor belt 405 reaches the baffle plate 309, the baffle plate 309 intercepts the metal casing 5. Subsequently, the traverse motor 302 drives the traverse screw 308 to rotate, and the traverse screw 308 drives the traverse frame 304 to move above the metal casing 5. Then, the lifting motor 305 rotates, driving the lifting screw 306 to rotate, and the lifting screw 306 drives the pick-and-place block 307 and the clamping plate 201 to move downwards. The side clamping plates 202 descend to the outside of the metal casing 5. Then, the clamping disc 201 continues to descend. When the central clamping post 310 contacts the metal casing 5, the clamping disc 201 continues to descend, applying an upward reaction force through the metal casing 5 to the central clamping post 310. This presses down the lower pressure plate 206, the rotating stud 207, and the rotating clamping disc 208, causing the four side clamping plates 202 to move inward. The side clamping plates 202 clamp the upper part of the metal casing 5. Then, the lifting motor 305 drives the loading and unloading... Block 307 and clamping plate 201 rise, thereby picking up the metal casing 5 from the conveyor belt 405. Then, the traverse motor 302 drives the traverse frame 304 to move above the clamping module on the main rotating disk 102. Then, the pick-up and put-down block 307 descends, placing the bottom of the metal casing 5 on the lower pressure plate 206 of the clamping module on the main rotating disk 102. Then, the pick-up and put-down block 307 continues to descend, so that the bottom of the metal casing 5 presses down on the lower pressure plate 206 of the clamping module on the main rotating disk 102. At this time, the four side clamping plates 202 The metal casing 5 moves inward and clamps the lower half of the metal casing 5. At the same time, the release column 111 contacts the release plate 204 of the clamping module on the pick-and-place block 307, causing the release plate 204 to rotate. This causes the four side clamping plates 202 to move outward, releasing the clamping module on the pick-and-place block 307 from clamping the metal casing 5. At this time, the metal casing 5 is transferred to the clamping module on the main rotating disk 102, and the clamping module on the pick-and-place block 307 remains open. Then, the pick-and-place block 307 rises back above the conveyor belt 405.

[0052] like Figures 11-13 As shown, the delivery mechanism includes an output frame 401 and a defective frame 402 fixedly installed on the intermediate frame 101. A conveyor motor 403 is fixedly installed on the output frame 401, and a conveyor belt 405 is provided on the output frame 401. The conveyor motor 403 drives the conveyor belt 405 to rotate through the transmission belt 404. A side conveyor belt 407 is provided on the defective frame 402. A take-up module is provided on both the output frame 401 and the defective frame 402.

[0053] like Figures 11-13As shown, the retrieval module includes a retrieval frame 408. The retrieval frame 408 of the retrieval module located on the output frame 401 is fixedly installed on the output frame 401. The retrieval frame 408 of the retrieval module located on the defective frame 402 is fixedly installed on the defective frame 402. Release frames 406 are fixedly installed on the output frame 401 and the defective frame 402 respectively. A side-moving motor 409 is fixedly installed on the retrieval frame 408. A side-moving lead screw 410 is rotatably installed on the retrieval frame 408. The side-moving lead screw 410 is fixedly installed with the motor shaft of the side-moving motor 409. A side-moving frame 411 is slidably installed on the retrieval frame 408. 11 forms a threaded transmission with the side moving lead screw 410. The side moving frame 411 is fixedly installed with the upper and lower motors 412. The upper and lower lead screws 413 are rotatably installed on the side moving frame 411. The upper and lower lead screws 413 are fixedly installed with the motor shafts of the upper and lower motors 412. The upper and lower blocks 414 are slidably installed on the side moving frame 411. The upper and lower blocks 414 form a threaded transmission with the upper and lower lead screws 413. A clamping module is provided on the upper and lower blocks 414. A release rod 415 is fixedly installed on the clamping plate 201 of the clamping module on the upper and lower blocks 414. A center column 416 is fixedly installed on the lower pressure plate 206 of the clamping module on the upper and lower blocks 414.

[0054] If the metal casing 5 passes the inspection, the take-up module on the output frame 401 will activate when the metal casing 5 moves to the side of the output frame 401 along with the main rotating disk 102. If the metal casing 5 fails the inspection, the take-up module on the unqualified frame 402 will activate when the metal casing 5 moves to the side of the unqualified frame 402 along with the main rotating disk 102.

[0055] When the qualified metal shell 5 moves to the output frame 401, the side-moving motor 409 drives the side-moving lead screw 410 to rotate. The side-moving lead screw 410 drives the side-moving frame 411 to move above the metal shell 5 on the main rotating disk 102. Then, the upper and lower motors 412 drive the upper and lower lead screws 413 to rotate. The upper and lower lead screws 413 drive the upper and lower blocks 414 and the clamping disk 201 to descend. When the release rod 415 contacts the release plate 204 of the clamping module on the main rotating disk 102, it drives the release plate 204 to rotate, so that the side clamping plate 202 on the main rotating disk 102 no longer clamps the lower half of the metal shell 5. At the same time, the central column 416 contacts the metal shell 5. Under the reaction force of the metal shell 5, the clamping module on the upper and lower blocks 414 is released. The side clamping plate 202 of the block clamps the upper half of the metal shell 5. Then, the upper and lower motors 412 drive the upper and lower blocks 414 and the metal shell 5 to rise. Then, the side motor 409 drives the upper and lower blocks 414 to reach above the side conveyor belt 407. Then, the upper and lower motors 412 drive the upper and lower blocks 414 to fall. When the release plate 204 of the clamping module on the upper and lower blocks 414 contacts the release frame 406, the release frame 406 causes the release plate 204 of the clamping module on the upper and lower blocks 414 to rotate, so that the side clamping plate 202 no longer clamps the metal shell 5. The metal shell 5 falls onto the conveyor belt 405 and is sent out by the conveyor belt 405. At this time, the clamping module on the upper and lower blocks 414 remains open and then returns to the initial position.

[0056] When the defective metal casing 5 moves to the defective frame 402, the side-moving motor 409 drives the side-moving lead screw 410 to rotate. The side-moving lead screw 410 drives the side-moving frame 411 to move above the metal casing 5 on the main rotating disk 102. Subsequently, the upper and lower motors 412 drive the upper and lower lead screws 413 to rotate. The upper and lower lead screws 413 drive the upper and lower blocks 414 and the clamping disk 201 to descend. When the release rod 415 contacts the release plate 204 of the clamping module on the main rotating disk 102, it drives the release plate 204 to rotate, thereby causing the side clamping plate 202 on the main rotating disk 102 to no longer clamp the lower half of the metal casing 5. At the same time, the central column 416 contacts the metal casing 5. Under the reaction force of the metal casing 5, the clamping module on the upper and lower blocks 414 is released. The side clamping plate 202 of the block clamps the upper part of the metal shell 5. Then, the upper and lower motors 412 drive the upper and lower blocks 414 and the metal shell 5 to rise. Then, the side motor 409 drives the upper and lower blocks 414 to reach above the side conveyor belt 407. Then, the upper and lower motors 412 drive the upper and lower blocks 414 to fall. When the release plate 204 of the clamping module on the upper and lower blocks 414 contacts the release frame 406, the release frame 406 causes the release plate 204 of the clamping module on the upper and lower blocks 414 to rotate, so that the side clamping plate 202 no longer clamps the metal shell 5. The metal shell 5 falls onto the side conveyor belt 407 and is sent out by the side conveyor belt 407. At this time, the clamping module on the upper and lower blocks 414 remains open and then returns to the initial position.

[0057] Working principle: When the lower tablet 206 is pressed down, it drives the rotating stud 207 and the bottom lifting block 205 to descend. The bottom lifting block 205 drives the release plate 204 to rotate relative to the fulcrum. With the threaded engagement between the clamping plate 201 and the rotating stud 207, the rotating stud 207 rotates, driving the rotating clamping plate 208 to rotate. The rotating clamping plate 208 drives the clamping guide post 210, the movable frame 211, and the side clamping plate 202 to move inward through the inclined slide groove 209. When the movable frame 211 moves inward, the side arc head 214 moves along the inner side slope 215. The side arc head 214 first moves along the concave part of the inner side slope 215 to the protrusion of the inner side slope 215. Then, after the side arc head 214 passes the protrusion, the retaining spring 213 rebounds, and the side arc head 214 moves to the inner side slope 215. The recessed portion on the outer side of slope 215 allows the side clamping plate 202 to clamp the metal shell 5. At this time, the side arc head 214 is located in the recessed portion on the outer side of the inner slope 215, and the retaining spring 213 is always in a compressed state. The recessed portion of the inner slope 215 has a certain range, so that the side arc head 214 of the retaining spring 213 can be kept in a recessed portion of the inner slope 215. When the retaining spring 213 is located in the recessed portion, the recessed portion can restrict the movement of the telescopic column 212 relative to the recessed portion, thereby limiting the side clamping plate 202 and preventing the side clamping plate 202 from loosening during clamping. This achieves stable clamping by the side clamping plate 202, allowing the side clamping plate 202 to clamp the metal shell 5 within a certain size range. When the outer end of the release plate 204 is pushed away from the lower pressure plate 206, the release plate 204 drives the bottom lifting block 205, the rotating stud 207 and the lower pressure plate 206 to rise. The rotating stud 207 drives the rotating clamping plate 208 to rotate. The rotating clamping plate 208 drives the clamping guide post 210, the movable frame 211 and the side clamping plate 202 to move outward through the inclined slide groove 209. At this time, the side arc head 214 passes the protrusion of the side inner slope 215 from the recessed part on the outside of the side inner slope 215 to the recessed part on the inside of the side inner slope 215, so that the side clamping plate 202 opens. At this time, the side clamping plate 202 no longer clamps the metal shell 5.

[0058] In use, the metal casing 5 to be tested is placed on the conveyor belt 405, which transports the metal casing 5. When the conveyor belt 405 reaches the baffle plate 309, the baffle plate 309 intercepts the metal casing 5. Subsequently, the traverse motor 302 drives the traverse screw 308 to rotate, and the traverse screw 308 drives the traverse frame 304 to move above the metal casing 5. Then, the lifting motor 305 rotates, driving the lifting screw 306 to rotate, and the lifting screw 306 drives the pick-and-place block 307 and the clamping plate 201 to move downwards. The side clamping plates 202 descend, reaching the outer side of the metal casing 5. Then, the clamping disc 201 continues to descend. When the central clamping post 310 contacts the metal casing 5, the clamping disc 201 continues to descend, applying an upward reaction force through the metal casing 5 to the central clamping post 310. This presses down the lower pressure plate 206, the rotating stud 207, and the rotating clamping disc 208, causing the four side clamping plates 202 to move inward. The side clamping plates 202 then clamp the upper part of the metal casing 5. Subsequently, the lifting motor 305 drives the pick-and-place block. 307 and clamping plate 201 rise, thereby picking up the metal casing 5 from the conveyor belt 405. Then, the traverse motor 302 drives the traverse frame 304 to move above the clamping module on the main rotating disk 102. Then, the pick-and-place block 307 descends, placing the bottom of the metal casing 5 on the lower pressure plate 206 of the clamping module on the main rotating disk 102. Then, the pick-and-place block 307 continues to descend, so that the bottom of the metal casing 5 presses down on the lower pressure plate 206 of the clamping module on the main rotating disk 102. At this time, the four side clamping plates 202 move towards... The internal movement clamps the lower half of the metal shell 5. At the same time, the release column 111 contacts the release plate 204 of the clamping module on the pick-and-place block 307, causing the release plate 204 to rotate, so that the four side clamping plates 202 move outward, causing the clamping module on the pick-and-place block 307 to release the clamp on the metal shell 5. At this time, the metal shell 5 is transferred to the clamping module on the main rotating disk 102, and the clamping module on the pick-and-place block 307 remains open. Then the pick-and-place block 307 rises back above the conveyor belt 405.

[0059] The bottom motor 109 drives the main rotating disk 102 to rotate via the lower transmission belt 110. The main rotating disk 102 drives the clamping module and the metal shell 5 to rotate 90 degrees each time. When the clamping module, carrying the metal shell 5, reaches the side of the detection frame 103, the lifting cylinder 104 extends, driving the lifting block 105 to descend, allowing the intelligent sensor 108 to enter the inner cavity of the metal shell 5. The detection motor 106 drives the detection column 107 and the intelligent sensor 108 to rotate. The intelligent sensor 108 measures the inner cavity dimensions of the metal shell 5, and in conjunction with the retraction of the lifting cylinder 104, it drives the intelligent sensor 108 to rise, enabling the intelligent sensor 108 to perform comprehensive detection of the inner cavity dimensions of the metal shell 5. The intelligent sensor 108 integrates a high-precision ranging module. When the intelligent sensor 108 rotates and rises inside the cavity, it continuously emits energy towards the inner wall of the cavity and receives reflected signals. By measuring the time difference or phase difference between emission and reception, the real-time distance from the center of the intelligent sensor 108 to the inner wall is calculated.

[0060] If the metal casing 5 passes the inspection, the take-up module on the output frame 401 will activate when the metal casing 5 moves to the side of the output frame 401 along with the main rotating disk 102. If the metal casing 5 fails the inspection, the take-up module on the unqualified frame 402 will activate when the metal casing 5 moves to the side of the unqualified frame 402 along with the main rotating disk 102.

[0061] When the qualified metal shell 5 moves to the output frame 401, the side-moving motor 409 drives the side-moving lead screw 410 to rotate. The side-moving lead screw 410 drives the side-moving frame 411 to move above the metal shell 5 on the main rotating disk 102. Then, the upper and lower motors 412 drive the upper and lower lead screws 413 to rotate. The upper and lower lead screws 413 drive the upper and lower blocks 414 and the clamping disk 201 to descend. When the release rod 415 contacts the release plate 204 of the clamping module on the main rotating disk 102, it drives the release plate 204 to rotate, so that the side clamping plate 202 on the main rotating disk 102 no longer clamps the lower half of the metal shell 5. At the same time, the central column 416 contacts the metal shell 5. Under the reaction force of the metal shell 5, the clamping module on the upper and lower blocks 414 is released. The side clamping plate 202 of the block clamps the upper half of the metal shell 5. Then, the upper and lower motors 412 drive the upper and lower blocks 414 and the metal shell 5 to rise. Then, the side motor 409 drives the upper and lower blocks 414 to reach above the side conveyor belt 407. Then, the upper and lower motors 412 drive the upper and lower blocks 414 to fall. When the release plate 204 of the clamping module on the upper and lower blocks 414 contacts the release frame 406, the release frame 406 causes the release plate 204 of the clamping module on the upper and lower blocks 414 to rotate, so that the side clamping plate 202 no longer clamps the metal shell 5. The metal shell 5 falls onto the conveyor belt 405 and is sent out by the conveyor belt 405. At this time, the clamping module on the upper and lower blocks 414 remains open and then returns to the initial position.

[0062] When the defective metal casing 5 moves to the defective frame 402, the side-moving motor 409 drives the side-moving lead screw 410 to rotate. The side-moving lead screw 410 drives the side-moving frame 411 to move above the metal casing 5 on the main rotating disk 102. Subsequently, the upper and lower motors 412 drive the upper and lower lead screws 413 to rotate. The upper and lower lead screws 413 drive the upper and lower blocks 414 and the clamping disk 201 to descend. When the release rod 415 contacts the release plate 204 of the clamping module on the main rotating disk 102, it drives the release plate 204 to rotate, thereby causing the side clamping plate 202 on the main rotating disk 102 to no longer clamp the lower half of the metal casing 5. At the same time, the central column 416 contacts the metal casing 5. Under the reaction force of the metal casing 5, the clamping module on the upper and lower blocks 414 is released. The side clamping plate 202 of the block clamps the upper part of the metal shell 5. Then, the upper and lower motors 412 drive the upper and lower blocks 414 and the metal shell 5 to rise. Then, the side motor 409 drives the upper and lower blocks 414 to reach above the side conveyor belt 407. Then, the upper and lower motors 412 drive the upper and lower blocks 414 to fall. When the release plate 204 of the clamping module on the upper and lower blocks 414 contacts the release frame 406, the release frame 406 causes the release plate 204 of the clamping module on the upper and lower blocks 414 to rotate, so that the side clamping plate 202 no longer clamps the metal shell 5. The metal shell 5 falls onto the side conveyor belt 407 and is sent out by the side conveyor belt 407. At this time, the clamping module on the upper and lower blocks 414 remains open and then returns to the initial position.
