Description

Technical Field

[0001] This invention relates to the field of product testing technology, and in particular to a highly efficient automated coil testing device. Background Technology

[0002] Tablet PCs typically incorporate coil structures for functions such as communication, charging, identification, or near-field interaction. After product manufacturing or assembly, the coil's coupling state and DCR parameters usually need to be tested to determine whether the coil assembly quality, electrical connection status, and electrical performance meet factory requirements. Since these coils are usually assembled as an integral part of the tablet casing, testing is often not performed on the coil itself, but rather the entire process of loading, positioning, testing, and unloading must be completed while the coil is installed inside the tablet casing.

[0003] Existing testing methods for coils inside flat plate housings typically involve manual loading, manual transfer, sequential testing at a single station, or testing after positioning. These methods can easily affect overall testing efficiency and consistency due to frequent transfer of the flat plate housing, insufficient positioning stability, or unsmooth testing connections. This is especially true when continuous coupling and DCR testing are required, making it difficult to balance positioning accuracy and automation.

[0004] Therefore, a highly efficient automated coil testing device is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-efficiency automated coil testing device, comprising a test bench, on which are sequentially arranged a manual loading position, a coupling loading position, multiple coupling test positions, a coupling unloading position, a DCR loading position, multiple DCR test positions, a DCR unloading position, and a lower-level picking position; the manual loading position is provided with a first transfer component, which is used to transfer a flat plate shell containing a coil from outside the device to the coupling loading position; each coupling test position is provided with a clamping component and a coupling test component, the clamping component is used to position and clamp the flat plate shell, and the coupling test component is used to abut against the test terminals of the coil inside the flat plate shell to perform coupling testing; a coupling test robot is provided between the coupling loading position and the coupling unloading position, and a [missing information - likely a device or mechanism] is provided between the DCR loading position and the DCR unloading position. The DCR testing robot, the coupling testing robot, and the DCR testing robot are all equipped with double-ended suction components at their ends. These components are used to simultaneously feed the flat shell to be tested into the testing area and remove and transfer the flat shell that has completed testing at the corresponding position. A second transfer component is provided at the DCR loading position to transfer the flat shell from the coupling unloading position to the receiving position of the DCR testing robot. Each DCR testing position is equipped with a movable frame, a clamping component mounted on the movable frame, and a DCR testing component. The movable frame receives and removes the flat shell, and the DCR testing component abuts against the conductive end of the coil inside the flat shell to perform the DCR test. A third transfer component is provided at the unloading position to transfer the flat shell from the DCR unloading position to the unloading position outside the equipment.

[0006] As a preferred embodiment of the present invention, the coupling test position is further provided with a transfer manipulator, which is located on one side of the clamping assembly. A manipulator gripper is fitted to the end of the transfer manipulator, and the transfer manipulator is used to transfer the flat plate shell between the coupling test manipulator and the clamping assembly. The clamping assembly includes a clamping platform, a fixed stop, a clamping block, an elastic stop, and a clamping cylinder. The clamping platform is disposed on the coupling test panel, the fixed stop is disposed on the rear and right sides of the clamping platform, the clamping block is slidably disposed on the front and left sides of the coupling test panel, the elastic stop is disposed at the end of the clamping block, and the clamping cylinder is... It is placed below the coupling test panel and connected to the clamping block so that the clamping block drives the elastic stop block to approach the flat plate shell and cooperates with the fixed stop block to clamp and position the flat plate shell; the coupling test assembly includes a back plate, a coupling test drive cylinder, a pressure block and a universal test probe module; the back plate is set on one side of the coupling test panel, the coupling test drive cylinder is set on the back plate, the pressure block is connected to the drive end of the coupling test drive cylinder, and the universal test probe module is set at the end of the pressure block; the pressure block is composed of two spaced L-shaped pressure blocks and a horizontal plate connecting the ends of the two L-shaped pressure blocks to form a clearance space at the bottom of the pressure block.

[0007] As a preferred embodiment of the present invention, the DCR test position includes a fixture support frame mounted on a test bench, a movable frame slidably mounted on a linear guide rail on the fixture support frame, and a reciprocating cylinder connected to the movable frame mounted on the fixture support frame; the DCR test assembly includes a DCR test panel, a DCR test drive cylinder mounted on the DCR test panel, and a DCR test needle mold mounted on the transmission end of the DCR test drive cylinder; the DCR test position also includes a temperature measuring component, which is configured to correspond to the detection area of ​​the DCR test needle mold, in order to detect the temperature of the test area during the DCR test process.

[0008] As a preferred embodiment of the present invention, the first, second, and third transfer components each include an electric slide, a slide plate connected to the slider of the electric slide, a lifting cylinder disposed on the slide plate, a clamping carrier plate connected to the transmission end of the lifting cylinder, and an adsorption component disposed on the clamping carrier plate; wherein, the first transfer component includes a first electric slide, a manual loading slide plate, a first lifting cylinder, a first clamping carrier plate, and a manual loading suction cup; the second transfer component includes a second electric slide, a DCR loading slide plate, a second lifting cylinder, a second clamping carrier plate, and a DCR loading suction cup; and the third transfer component includes a third electric slide, a unloading slide plate, a third lifting cylinder, a third clamping carrier plate, and an unloading suction cup; corresponding to the pick-up and placement positions of the first, second, and third transfer components, a first unloading support plate, a fourth unloading support plate, a fifth unloading support plate, and a sixth unloading support plate for supporting the flat shell are respectively provided, and each unloading support plate is provided with a groove adapted to the shape of the flat shell.

[0009] As a preferred embodiment of the present invention, the dual-end suction assembly includes a material picking and fixing plate, with a material picking and lifting cylinder respectively provided at both ends of the material picking and fixing plate, a material tray transfer fixing component provided at the transmission end of the material picking and lifting cylinder, and a material picking suction cup provided on the material tray transfer fixing component.

[0010] As a preferred embodiment of the present invention, the coupling test position is set to at least two, and the DCR test position is set to two. The two DCR test positions are arranged opposite each other to the left and right, so that the coupling test robot and the DCR test robot can alternately transfer the plate shell to be tested by feeding one end into the plate shell to be tested and taking out the plate shell that has completed the current process test by taking out the other end.

[0011] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention, by setting up a transfer mechanism capable of performing alternating feeding and picking actions, and by making the coupling test process and the DCR test process run in a continuous connection manner, allows the flat plate shell under test to be simultaneously taken out and transferred to the next station while the flat plate shell that has completed the corresponding test is entering the coupling test station. This reduces the idle travel and waiting time caused by simple back-and-forth material picking. At the same time, combined with the alternating material receiving and alternating testing method of the DCR test station, the flat plate shell along with the internal coil can complete the coupling test and DCR test in a continuous flow manner. This improves the overall testing cycle time and enhances the automated continuous operation capability, and is especially suitable for batch testing scenarios where the flat plate shell is in the coil assembled state.

[0012] 2. This invention uses a reference limit and clamping fixation on the flat plate shell, and checks the placement state of the flat plate shell before testing. After confirming that the position and posture of the flat plate shell meet the requirements, the test needle mold is pressed down to make contact. This ensures that the coil maintains good placement stability and contact consistency when tested with the flat plate shell. At the same time, temperature detection of the test area during DCR testing helps to reduce the impact of temperature changes on the judgment of test results, thereby improving the stability of the coil testing process and the accuracy of the test results, making the final coupling test results and DCR test results more reliable and consistent.

Detailed Implementation

[0015] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0016] Example: Figure 1 , Figure 2 and Figure 3 As shown, a high-efficiency automated coil testing device includes a test bench 1. The test bench 1 is covered by a device shell made of sheet metal frame. The opening of the device shell is provided with a device door. Inside the device shell, conventional electrical control components such as a control cabinet, control host, and cooling fan are installed through sheet metal instrument fasteners. The right side of the test bench 1 has reserved activity space, which constitutes a maintenance station 101. Maintenance personnel can stand in the maintenance station 101 to inspect and maintain the internal parts of the device by opening the rear door of the device.

[0017] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a coupling test station 2 is provided on the right side of the maintenance station 101. The coupling test station 2 includes a device base 201, a clamping assembly, and a coupling test assembly. The four corners of the bottom surface of the device base 201 are equipped with horizontal adjustment wheels to allow for horizontal adjustment and fine-tuning of the device base 201 during installation. A support frame 202 is mounted on the top surface of the left end of the device base 201. The electrical control components, pneumatic modules, and related mounting parts required for the coupling test are arranged on the device base 201 and the support frame 202. A coupling test panel 203 is mounted on the top surface of the support frame 202, and the clamping assembly is located on the top surface of the coupling test panel 203. The clamping assembly includes a clamping platform 204, a fixed stop 205, a clamping block 206, an elastic stop 207, and a clamping cylinder 208. The clamping platform 204 is mounted on the top surface of the coupling test panel 203, and the rear and right sides of the top surface of the clamping platform 204 are also included. Fixed stops 205 are respectively installed to limit the rear and right sides of the flat plate shell. Sliding holes are opened on the front and left sides of the top surface of the coupling test panel 203. Clamping blocks 206 are slidably connected in the sliding holes. Elastic stops 207 are installed at the ends of clamping blocks 206. Elastic stops 207 can form a buffer clamping on the flat plate shell through elastic elements. Two clamping cylinders 208 are installed on the bottom surface of the coupling test panel 203. The transmission ends of the two clamping cylinders 208 are respectively connected to the two clamping blocks 206. In use, the flat plate shell with coil is placed on the clamping table 204. Fixed stops 205 initially position the flat plate shell. Clamping cylinders 208 drive clamping blocks 206 to move closer to the flat plate shell, so that elastic stops 207 press against the flat plate shell from the front and left sides respectively, thereby stably clamping the flat plate shell on the clamping table 204 to ensure the contact stability of subsequent coupling tests.

[0018] like Figure 4 , Figure 5 and Figure 6As shown, a transfer robot 209 is mounted on the right side of the support frame 202. The transfer robot 209 is preferably a six-axis multi-joint robot. The end of the transfer robot 209 is equipped with a robot gripper 210, which can be a pneumatic gripper or a magnetic gripper structure. The transfer robot 209 is used to drive the robot gripper 210 to approach the flat plate shell that has been transported to the position, and to clamp the flat plate shell and place it on the clamping table 204.

[0019] The coupling test assembly includes a back plate 211, which is connected to the top surface of the support frame 202 and located on the right side of the coupling test panel 203. The bottom of the back plate 211 has an opening for the end of the transfer robot 209 to pass through. A coupling test drive cylinder 212 is mounted on the right side of the back plate 211, and a pressure block 213 is connected to the transmission end of the coupling test drive cylinder 212. The pressure block 213 consists of two spaced L-shaped pressure blocks and a horizontal plate connecting the ends of the two L-shaped pressure blocks, thereby forming a clearance space at the bottom of the pressure block 213. A universal test probe module 214 is mounted on the horizontal plate at the end of the pressure block 213. The universal test probe module 214 is preferably an elastic probe type test module and is electrically connected to an external coupling test circuit. After the plate shell is clamped by the clamping assembly, the coupling test drive cylinder 212 drives the pressure block 213 to descend, so that the universal test probe module 214 abuts against the coil test terminal inside the plate shell, thereby completing the coupling test.

[0020] like Figure 4 and Figure 6 As shown, a first camera 215 is mounted on the left side of the backplate 211 above the universal test probe module 214. A mounting bracket 216 is mounted on the inner top of the support frame 202, and a camera light source 217 is mounted on the mounting bracket 216. The first camera 215 and the camera light source 217 are arranged vertically in correspondence. The coupling test panel 203 and the clamping stage 204 have common clearance openings 218 at the detection positions corresponding to the first camera 215, so that the first camera 215 can capture and identify the flat shell through the clearance openings 218. Specifically, the first camera 215 is used to detect the flat shell on the clamping stage 204. The position, posture, and positioning status of the camera are monitored. The camera light source 217 is used to supplement the illumination of the detection area, improving the accuracy and stability of the detection by the first camera 215. In other embodiments, the clamping assembly also includes a suction cup group 219. A through hole is provided in the coupling test panel 203 and the clamping stage 204. The suction cup group 219 is installed in the through hole and connected to a negative pressure source so that the plate shell can be further adsorbed from the bottom on the basis of the clamping cylinder 208, preventing the plate shell from tilting or undergoing slight displacement. Furthermore, the number of coupling test positions 2 can be set to one or more according to the cycle requirements.

[0021] like Figure 3 , Figure 9 and Figure 10As shown, a DCR test position 3 is provided on the rear side of the test bench 1. The DCR test position 3 includes a fixture support frame 301 and a DCR test assembly. The fixture support frame 301 is mounted on the test bench 1. A linear guide rail 302 is mounted on the top surface of the fixture support frame 301. The linear guide rail 302 is used to guide and support the reciprocating movement of the movable frame 304 to ensure the stability and repeatability of the transfer process. A reciprocating cylinder 303 is also mounted on the top surface of the fixture support frame 301. The movable frame 304 is mounted on the slider of the linear guide rail 302. The transmission end of the reciprocating cylinder 303 is connected to the movable frame 304, thereby driving the movable frame 304 along the linear guide rail 302. 2. Reciprocating motion; the movable frame 304 is formed by connecting two upper and lower plates through columns. Components required for DCR testing, such as the IG junction box, solenoid valve, and pressure gauge, are installed between the upper and lower plates. The top surface of the movable frame 304 is also equipped with the same clamping assembly as the coupling test position 2, used to stably clamp the flat shell. The DCR testing assembly includes a DCR testing panel 305, which is mounted on one side of the top surface of the fixture support frame 301. The DCR testing panel 305 includes two corresponding vertical plates and a horizontal plate connected to the top of the two vertical plates. A DCR testing drive cylinder 306 is mounted on the side of the horizontal plate. The transmission end of 306 is equipped with a cylinder connecting block 307, which extends toward the movable frame 304, and a DCR test needle mold 308 is mounted at one end corresponding to the movable frame 304. The DCR test needle mold 308 is preferably an elastic probe type test needle mold and is electrically connected to an external DCR tester. A temperature measuring component 309 is also mounted on the side of the cylinder connecting block 307 above the movable frame 304. The temperature measuring component 309 includes a temperature sensor, which is tilted via a sheet metal mounting block. Its detection end corresponds to the detection area of ​​the DCR test needle mold 308, so as to simultaneously acquire the temperature information of the plate shell or coil test point during the DCR test. This improves the reliability of DCR test results. Preferably, there are two DCR test positions 3, arranged opposite each other to form an alternating material receiving and testing rhythm with the preceding and following processes. In use, the flat shell that has completed the coupling test is placed on the clamping assembly on the top surface of the movable frame 304 and clamped. The DCR test drive cylinder 306 drives the DCR test needle mold 308 to descend and abut against the coil conduction end to complete the DCR test. At the same time, the temperature measuring assembly 309 detects the temperature of the test area. After the test, the DCR test drive cylinder 306 drives the DCR test needle mold 308 to rise and reset, and the clamping assembly releases the clamping assembly from the flat shell for subsequent removal.

[0022] like Figure 3 and Figure 11As shown, a manual loading position 4 is provided on the right side of the test bench 1 via a fixing component. The manual loading position 4 is located outside the equipment shell, and the equipment shell has an inlet corresponding to the position of the manual loading position 4. The manual loading position 4 includes a loading protective cover 401, with openings on the top and left sides. Safety light curtains 402 are installed on the front and rear sides of the top surface of the loading protective cover 401 to ensure the safety of operation during the manual loading process. A first scanning bracket 403 is mounted on the top left side of the inner wall of the loading protective cover 401. A first scanner 404 is mounted on the end of the first scanning bracket 403 above the safety light curtain 402. The first scanner 404 is preferably a CCD scanner. The scanning end of the first scanner 404 faces downward and corresponds to the inside of the loading protective cover 401, and is used to scan and identify the barcode, QR code or identity information of the plate shell to be loaded.

[0023] like Figure 3 and Figure 12 As shown, the manual loading station 4 also includes a first base plate 405 and a first transfer assembly. The first base plate 405 is mounted on the top surface of the test bench 1. The first base plate 405 is located on the left side of the loading protective cover 401 and partially extends into the loading protective cover 401. The first transfer assembly includes a first electric slide 406, which is mounted on the top surface of the first base plate 405. The first electric slide 406 preferably adopts a screw module or a synchronous belt module to drive the manual loading slide plate 407 to move in the left and right directions. The slider of the first electric slide 406 is equipped with the manual loading slide plate 407. The top surface of the manual loading slide plate 407 is equipped with a vertically arranged cylinder support plate. The cylinder support plate is equipped with a first lifting cylinder 408. The transmission end of the first lifting cylinder 408 faces upward and is equipped with a first clamping carrier plate 409. The first clamping carrier plate 409 has a through hole, and a through hole is installed in the through hole. The device includes a manual feeding suction cup 410 connected to a negative pressure source; a manual feeding slide plate 407 is also equipped with components such as a solenoid valve and a vacuum pressure gauge; the front and rear ends of the right side of the first base plate 405 are each equipped with a first discharge support plate 411 via a column, the two first discharge support plates 411 are located inside the feeding protective cover 401, and the opposite surfaces are each provided with a groove that matches the shape of the flat shell; during manual feeding, the flat shell is placed on the first discharge support plate 411 from above, the first lifting cylinder 408 drives the first clamping carrier plate 409 to rise, the manual feeding suction cup 410 adheres to the bottom surface of the flat shell and uses negative pressure to adsorb and fix the flat shell, then the first clamping carrier plate 409 continues to rise, causing the flat shell to detach from the first discharge support plate 411, and the first electric slide 406 drives the manual feeding slide plate 407 to move to the left, sending the flat shell into the equipment shell.

[0024] like Figure 3 and Figure 12As shown, a coupling scanning position 5 is provided on the first base plate 405. The coupling scanning position 5 includes a second scanning bracket 501, which is mounted on the first base plate 405. A second scanner 502 is mounted on the end of the second scanning bracket 501. The second scanner 502 is preferably a CCD scanner. During the process of the first clamping carrier plate 409 transporting the flat shell into the equipment, the flat shell passes through the coupling scanning position 5. The second scanner 502 can scan and check the appearance, position status or identification information of the flat shell again.

[0025] like Figure 3 and Figure 12 As shown, a coupling loading position 6 is provided on the left side of the top surface of the first base plate 405. The coupling loading position 6 includes a second feeding support plate 601. The second feeding support plate 601 is set as two plates, one in front and one behind, and fixed to the first base plate 405 by columns. The opposite surfaces of the two second feeding support plates 601 are also provided with grooves that are adapted to the shape of the flat plate shell. After the manual feeding slide plate 407 moves to the left end, the first lifting cylinder 408 drives the first clamping plate 409 to descend. At the same time, the manual feeding suction cup 410 releases the negative pressure adsorption on the flat plate shell, so that the flat plate shell is placed stably on the second feeding support plate 601, thereby completing the feeding transfer from the manual feeding position 4 to the coupling loading position 6.

[0026] like Figure 3 and Figure 13 As shown, a coupling unloading position 7 is provided on the left side of the manual loading position 4 on the top surface of the test bench 1. The coupling unloading position 7 includes a second base plate 701. The second base plate 701 is assembled on the top surface of the test bench 1. The front and rear ends of the right side of the top surface of the second base plate 701 are equipped with third feeding support plates 702 through columns. The opposite surfaces of the two third feeding support plates 702 are provided with grooves that are adapted to the shape of the flat plate shell, which are used to receive the flat plate shell after the coupling test is completed.

[0027] like Figure 3 and Figure 15As shown, a coupling test manipulator 8 is installed on the top surface of the test bench 1. The coupling test manipulator 8 is preferably a six-axis multi-joint manipulator. A double-end suction assembly 9 is mounted at the end of the coupling test manipulator 8. The double-end suction assembly 9 includes a material-picking fixing plate 901, which is mounted at the end of the coupling test manipulator 8. Both ends of the material-picking fixing plate 901 are equipped with material-picking lifting cylinders 902. The transmission ends of the material-picking lifting cylinders 902 are respectively equipped with material tray transfer fixing parts 903. Through holes are opened at the four corners of the material tray transfer fixing parts 903, and material-picking suction cups 904 are installed in the through holes. The material-picking suction cups 904 are connected to a negative pressure source. The material-picking fixing plate 901 is also equipped with pneumatic components such as a solenoid valve and a vacuum pressure gauge. During operation, the coupling test manipulator 8 drives the double-end suction assembly 9 to move above the second material-discharging support plate 601, with one end... The suction cup 904 uses negative pressure to adsorb the flat shell to be coupled for testing. Then, the coupling test robot 8 transports the flat shell to the coupling test position 2. The transfer robot 209 takes over and places the flat shell on the clamping table 204. During this process, the transfer robot 209 at another location clamps and transports the flat shell that has completed the coupling test to the receiving position. The suction cup 904 at the other end of the double-end suction component 9 simultaneously adsorbs the flat shell that has completed the coupling test. Then, the coupling test robot 8 moves back to the second feeding support plate 601 and transfers the flat shell that has completed the coupling test to the third feeding support plate 702, completing the workpiece transfer on both sides. The above actions are repeated to continuously send the flat shell to be tested into the coupling test position 2 and the flat shell that has completed the test into the third feeding support plate 702, thus realizing continuous material change.

[0028] like Figure 3 and Figure 13 As shown, a DCR scanning position 10 is provided in the middle of the top surface of the second base plate 701. The DCR scanning position 10 includes a third scanning bracket 1001. A third scanner 1002 is assembled at the end of the third scanning bracket 1001. The third scanner 1002 is preferably a CCD barcode scanner. The detection end of the third scanner 1002 faces downward and is used to perform identity verification, transfer confirmation or status scanning on the flat plate shell that is about to enter the DCR testing process after completing the coupling test.

[0029] like Figure 3 and Figure 13As shown, the top surface of the second base plate 701 is also provided with a DCR loading position 11, which includes a second transfer assembly. The structure of the second transfer assembly is basically the same as that of the first transfer assembly, both including an electric slide, a sliding plate, a lifting cylinder, a clamping support plate, and an adsorption assembly. The difference lies in the installation position and the docking support plate. Specifically, the second transfer assembly includes a second electric slide 1101, which is mounted on the second base plate 701, and one end of which is located below the third unloading support plate 702. The second electric slide 1101 preferably adopts a screw module or a synchronous belt module. The DCR loading sliding plate 1102 is connected to its slider. A vertical cylinder support plate is mounted on the top surface of the DCR loading sliding plate 1102. A second lifting cylinder 1103 is mounted on the cylinder support plate. The transmission end of the second lifting cylinder 1103 faces upward and is mounted with a second clamping support plate 1104. The second base plate 701 has a through hole, in which a DCR feeding suction cup 1105 is installed. The DCR feeding suction cup 1105 is connected to a negative pressure source. The assembly containing the DCR feeding slide plate 1102 is also equipped with pneumatic components such as a solenoid valve and a vacuum pressure gauge. The front and rear ends of the left side of the second base plate 701 are equipped with fourth discharge support plates 1106 via columns. The opposite surfaces of the two fourth discharge support plates 1106 are provided with grooves that fit the flat plate shell. During operation, the second clamping carrier plate 1104 rises under the drive of the second lifting cylinder 1103. The DCR feeding suction cup 1105 adsorbs the flat plate shell on the third discharge support plate 702 and lifts it away. Then, the second electric slide 1101 drives the DCR feeding slide plate 1102 to move to the left, transporting the flat plate shell above the fourth discharge support plate 1106. The second lifting cylinder 1103 descends and releases the adsorption, thereby transferring the flat plate shell that has completed the coupling test to the material pick-up position required for the DCR test.

[0030] like Figure 3 and Figure 14 As shown, a DCR unloading position 12 is provided on the left side of the coupling unloading position 7 on the top surface of the test bench 1. The DCR unloading position 12 includes a third base plate 1201. The third base plate 1201 is assembled on the test bench 1. The front and rear ends of the right side of the top surface of the third base plate 1201 are connected to the fifth feeding support plate 1202 through columns. The opposite surfaces of the two fifth feeding support plates 1202 are provided with grooves that are adapted to the flat plate shell, which are used to receive the flat plate shell after the DCR test is completed.

[0031] like Figure 3 and Figure 16As shown, a DCR testing robot 13 is installed on the top surface of the test platform 1. The DCR testing robot 13 can be a robot model with rotation and lifting functions. The end of the DCR testing robot 13 is also equipped with a double-ended suction assembly 9. The DCR testing robot 13 is used to transfer and change the flat shell between the fourth feeding support plate 1106, the DCR testing position 3, and the fifth feeding support plate 1202. Specifically, the DCR testing robot 13 uses the suction cup 904 on one side to pick up the flat shell on the fourth feeding support plate 1106 and transport it to the left and right opposite sides. One of the DCR test positions 3 is located at the receiving position. The corresponding movable frame 304 is moved to the receiving position by the reciprocating cylinder 303. The DCR test robot 13 releases the negative pressure adsorption and places the flat shell on the clamping component on the top surface of the movable frame 304. At the same time, the other DCR test position 3 can move the flat shell that has completed the DCR test to the picking position. The DCR test robot 13 then uses the picking suction cup 904 on the other side to adsorb and pick up the flat shell that has completed the DCR test. By alternating the cooperation of the two DCR test positions 3, continuous receiving, continuous testing and continuous unloading can be achieved.

[0032] like Figure 3 and Figure 14As shown, a lower workstation material pick-up position 14 is provided on the third base plate 1201; the lower workstation material pick-up position 14 includes a third transfer assembly, the structure of which is basically the same as that of the second transfer assembly, both including an electric slide, a sliding plate, a lifting cylinder, a clamping carrier plate, and an adsorption assembly, the difference being the installation position and the discharge direction; specifically, the third transfer assembly includes a third electric slide 1401, which is mounted on the third base plate 1201, and one end of which is located on the fifth discharge support plate 1202. Below; the third electric slide 1401 preferably adopts a lead screw module or a synchronous belt module, and a feeding slide 1402 is connected to its slider. A vertical cylinder support plate is mounted on the top surface of the feeding slide 1402. A third lifting cylinder 1403 is mounted on the cylinder support plate. The transmission end of the third lifting cylinder 1403 faces upward and is equipped with a third clamping carrier plate 1404. A through hole is opened on the third clamping carrier plate 1404, and a feeding suction cup 1405 is installed in the through hole. The feeding suction cup 1405 is connected to a negative pressure source; the component containing the feeding slide 1402. It is also equipped with pneumatic components such as solenoid valves and vacuum pressure gauges; the front and rear ends of the left side of the third base plate 1201 are both equipped with sixth discharge support plates 1406 via columns, and the opposite surfaces of the two sixth discharge support plates 1406 are provided with grooves that fit the flat plate shell; a discharge hole is provided on the left side of the equipment shell, and part of the third base plate 1201 and the sixth discharge support plates 1406 are located outside the equipment shell; during operation, the DCR testing robot 13 places the flat plate shell that has completed the DCR test onto the fifth discharge support plate 1202, and the third The three lifting cylinders 1403 drive the third clamping carrier plate 1404 to rise, the unloading suction cup 1405 adsorbs the bottom surface of the flat shell and lifts it away from the fifth unloading support plate 1202, then the third electric slide 1401 drives the unloading slide plate 1402 to move to the left, transporting the flat shell to the top of the sixth unloading support plate 1406, the third lifting cylinder 1403 descends and releases the adsorption, thus placing the flat shell that has completed all tests on the sixth unloading support plate 1406, after which the finished product can be taken away by the robot arm of other automated equipment or manually.

[0033] In this embodiment, the various plates, brackets, and fixing parts can be assembled and connected using fasteners such as screws and nuts; the control of each transfer position, lifting position, and final position can be achieved through the cooperation of sensors, limit switches, and control circuits to ensure the coordination of the machine's movements and the stability of its cycle time.

[0034] Working principle: Before use: The equipment is in standby preparation state; the operator first confirms the structural integrity of test bench 1, equipment shell, equipment door, and each workstation, and connects the control cabinet, control host, cooling fan, negative pressure source, air source, and external test circuit to bring the whole machine into an operational state; then, the coupling test position 2, DCR test position 3, manual loading position 4, coupling scan position 5, coupling loading position 6, coupling unloading position 7, DCR scan position 10, DCR loading position 11, DCR unloading position 12, and lower workstation material picking position 14 are initially reset, so that the coupling test robot 8, transfer robot 209, and DCR test robot 13 return to their preset initial positions, and each clamping cylinder 208, coupling test drive cylinder 212, and reciprocating cylinder... Cylinder 303, DCR test drive cylinder 306, first lifting cylinder 408, second lifting cylinder 1103, and third lifting cylinder 1403 are all in the release or rising reset state. Each electric slide is in the starting position, and each material suction cup 904, manual feeding suction cup 410, DCR feeding suction cup 1105, and unloading suction cup 1405 is in the adsorption state. At the same time, the corresponding detection channels are self-checked and calibrated by the first scanner 404, the second scanner 502, the third scanner 1002, the first camera 215, and the temperature measuring component 309 to ensure the accuracy of subsequent identification, positioning, testing, and temperature detection. After the plate shell to be tested is placed on the first unloading support plate 411 of the manual feeding position 4, the automatic testing process can begin.

[0035] In use: The operator places the flat plate containing the coil onto the first feeding support plate 411 of the manual feeding position 4. The first scanner 404 scans and identifies the barcode, QR code, or identity information of the flat plate. After confirming the incoming material information, the first lifting cylinder 408 drives the first clamping carrier plate 409 to rise, causing the manual feeding suction cup 410 to adhere to the bottom surface of the flat plate. Subsequently, the first electric slide 406 moves the manual feeding slide plate 407 to the inside of the equipment. During the conveying process, the second scanner 502 scans and checks the flat plate again. After moving to the coupling feeding position 6, the first lifting cylinder... 408 drives the first clamping carrier plate 409 to descend and release the adsorption, so that the flat shell is placed on the second feeding support plate 601; then, the coupling test robot 8 uses the material suction cup 904 at one end of the double-ended suction component 9 to pick up the flat shell to be tested on the second feeding support plate 601 and send it to the corresponding coupling test position 2. At the same time, the material suction cup 904 at the other end of the double-ended suction component 9 simultaneously picks up the flat shell that has completed the coupling test in another coupling test position 2. The flat shell to be sent is clamped by the corresponding transfer robot 209 and placed on the clamping table 204, and then stopped by the fixed stop 205. The clamping block 206, elastic stop 207, and clamping cylinder 208 work together to complete the positioning and clamping. The first camera 215, assisted by the camera light source 217, detects the position, attitude, and positioning of the flat plate. After confirming that everything is correct, the coupling test drive cylinder 212 drives the pressure block 213 to move downwards, causing the universal test probe module 214 to contact the coil test terminal inside the flat plate, completing the coupling test. Simultaneously, the coupling test robot 8 continues to move, delivering the flat plate, which has completed the coupling test and is held at the other end, to the third unloading support plate 702 corresponding to the coupling unloading position 7. During the process of placing the tested flat shell onto the third feeding support plate 702, the end of the double-ended suction component 9, which was originally used to feed the workpiece, simultaneously suctions the next flat shell to be tested on the second feeding support plate 601, so that the coupling test robot 8 can complete the material exchange action in the same return process. Subsequently, the coupling test robot 8 sends the newly suctioned flat shell to be tested to the vacated coupling test position 2, and simultaneously takes away the flat shell that has been tested in another coupling test position 2. This cycle forms a continuous material exchange cycle of alternating double-ended feeding and taking, so as to reduce idle stroke and improve coupling test efficiency.After the flat plate shell that has completed the coupling test is placed on the third feeding support plate 702, the third scanner 1002 performs identity verification, flow confirmation, or status scanning on it. Then, the second lifting cylinder 1103 drives the second clamping carrier plate 1104 to rise, so that the DCR feeding suction cup 1105 adsorbs the flat plate shell on the third feeding support plate 702. Driven by the second electric slide 1101, it is transferred to the fourth feeding support plate 1106. Then, the DCR testing robot 13 adsorbs and transports it to the corresponding DCR testing position 3. After the movable frame 304 moves to the receiving position under the drive of the reciprocating cylinder 303, the clamping component clamps the flat plate shell. The DCR testing drive cylinder 306 drives the DCR testing needle mold 308 to move down and abut against the coil conduction end, thereby completing the DCR test. The temperature measuring component 309 simultaneously detects the temperature of the test area. When a DCR testing position 3 performs a test... During testing, another DCR testing station 3 can simultaneously receive or discharge materials. The DCR testing robot 13 and the coupled testing robot 8 share the same transfer logic; both use the suction cups 904 at both ends of the double-ended suction assembly 9 to simultaneously remove the flat shell that has completed the current process test while feeding it in, thus achieving alternating discharge. After the DCR test is completed, the DCR testing robot 13 transfers the flat shell and places it on the fifth discharge support plate 1202. The third lifting cylinder 1403 drives the third clamping carrier plate 1404 to rise, causing the discharge suction cup 1405 to adhere to the bottom surface of the flat shell and lift it away from the fifth discharge support plate 1202. Subsequently, the third electric slide 1401 drives the discharge slide plate 1402 to move outward, transporting the flat shell that has completed all tests to the sixth discharge support plate 1406 and releasing it. Finally, the finished product is removed manually or by other automated equipment.

[0036] After use: When a batch of flat shells completes testing or the equipment needs to be stopped, the control system controls each station to stop the feeding, testing, transfer, and unloading actions in sequence, so that the coupled testing robot 8, the transfer robot 209, and the DCR testing robot 13 return to their initial safe positions, each test needle mold and clamping mechanism returns to the released state, and each lifting cylinder and electric slide returns to its initial position, avoiding the retention of workpieces inside the equipment or the workpieces remaining in a suspended state; subsequently, the operator can remove the flat shells on the sixth unloading support plate 1406 manually or by other automated equipment, and the first unloading support plate 411 and the second unloading support plate... 601, the third feeding support plate 702, the fourth feeding support plate 1106, the fifth feeding support plate 1202, and the sixth feeding support plate 1406 are cleaned and inspected; at the same time, routine maintenance or calibration is performed on the general test probe module 214, the DCR test probe module 308, each suction cup, each scanner, the first camera 215, and the temperature measurement component 309; if the equipment needs to be repaired, maintenance personnel can enter the maintenance station 101 to maintain the control cabinet, control host, pneumatic components, electrical control circuits, and related actuators inside the equipment casing to ensure that the equipment can still maintain stable and efficient automated testing capabilities when used again.
