[0002] With the development of the automobile industry, the safety and comfort of vehicles have attracted more and more attention from consumers. As one of the important components to improve the vehicle experience, the performance of electric window lifters directly affects the user satisfaction. There are many types of electric window lifters on the market. In order to ensure product quality, manufacturers need to conduct strict quality inspections on each batch of products produced. These inspections are not limited to mechanical strength, but also include electrical characteristics, durability and other aspects.

[0003] However, currently most of the existing electric window lifts are inspected manually. However, since there are many parts and contents to be inspected, the inspection efficiency caused by manual inspection will decrease with the number of inspections and the length of manual inspection time during batch inspection, so it needs to be improved.

[0006] By adopting the above technical scheme, the product under test is positioned on the support table, and the controller controls the loading and unloading parts to connect the docking plate to the slider, and then the pull rope is pulled by the motor under test, so that the slider drives the docking plate to slide relative to the carrier plate. In this process, the detection module is used to detect the pulling force of the pull rope when the slider slides during the sliding process of the slider, as well as the current data input by the power supply to the motor under test to the motor under test. The controller is used to analyze the feedback signal of whether the product under test is qualified based on the above-mentioned detection results. On the one hand, automatic detection of the product under test is realized to improve the detection efficiency. On the other hand, the detection module can be used to detect data that cannot be detected by manual visual inspection, thereby improving the comprehensiveness, accuracy and efficiency of detection.

[0007] Preferably, the detection module specifically includes a first detection module for detecting whether the structure of the product under test is complete, a second detection module for identifying the information of the motor under test, a third detection module for contacting the docking plate connected to the slider and detecting the pressure of the docking plate when in contact with the docking plate, and a fourth detection module for detecting current data of the input motor under test.

[0009] Preferably, a plurality of locking plates are rotatably connected to the support table, a gap is reserved between the locking plates and the support table for the insertion of the tested product, and when the locking plates are rotated to the side of the tested product away from the support table, the locking plates are in contact with the surface of the tested product; a first rotating member for driving the locking plates to rotate is provided on the support table; the loading and unloading parts include a support frame, a sliding member for driving the support frame to slide in a direction close to or away from the support table, a lifting member for driving the support plate to rise and fall, and a limit roller rotatably connected to the detection table, and a limit rope wound around the limit roller; a limit torsion spring is connected between the limit roller and the detection table, and one end of the limit rope away from the limit roller is connected to the docking plate, and a receiving groove for the docking plate to be inserted is provided on the support frame, and the lifting direction of the lifting member for driving the support plate to rise and fall is parallel to the sliding direction of the slider of the tested product on the support table relative to the carrier plate.

[0010] By adopting the above technical solution, after the product to be tested is placed on the support plate, the first rotating member is used to drive the locking plate to rotate and fit the surface of the product to be tested, thereby achieving the fixation of the product to be tested relative to the support plate. In addition, when the support frame is used to move and transport the docking plate, the docking plate is always connected to the limit rope, that is, the limit rope and the limit torsion spring are used to improve the movement stability of the docking plate during the transportation process and the process of being driven by the slider to slide.

[0011] Preferably, the support table is rotatably connected to the detection table, and a second rotating member for driving the support table to rotate is provided on the detection table. A plurality of inclined points are provided on the detection table, and the inclined points are located on the moving path when the slider on the support table slides relative to the carrier plate and moves with the rotation of the support table. The third detection module is used to detect the resistance pressure of the docking plate when it contacts the docking plate at each inclined point.

[0012] By adopting the above-mentioned technical solution, the tension required by the pull rope of the tested product on the support table to pull the slider to slide will vary with the different inclination angles of the support table. Therefore, the present application proposes to drive the support table to rotate so that the support table is tilted relative to the testing platform to form different inclination angles, and then use the third detection module to detect the tension of the pull rope on the support table on the slider at different inclination angles, so as to further improve the comprehensiveness of the detection.

[0013] Preferably, a driving gear is rotatably connected to the support table, and the driving gear is meshingly connected to a driven rack. The driven rack is slidably connected to the support table, and the sliding direction is parallel to the sliding direction of the slider on the support table when it slides relative to the carrier plate. The third detection module is connected to the driven rack, and the moving path of the third detection module when it slides with the driven rack and moves with the rotation of the support table just includes all the tilting points; an arc-shaped docking plate is provided on the detection table, and a tooth groove meshing with the driven gear is provided on the arc surface of the arc-shaped docking plate. When the support table rotates relative to the detection table, the driven gear always meshes with the tooth groove on the arc-shaped docking plate as the support table rotates.

[0014] By adopting the above technical solution, when the supporting table rotates, the driving gear rotates during the meshing process with the arc-shaped docking plate, and drives the driven rack and the third detection module connected to the driven rack to slide, so that the third detection module can move to the inclined point during this process.

[0015] Preferably, the support table is provided with a support frame for placing the tested product, and also includes a lifting member, a moving member, a material receiving frame and a material feeding frame; the driving end of the lifting member is connected to the support frame to drive the support frame to move toward or away from the support table, and the moving member is used to drive the lifting member and the support frame to reciprocate along the width direction of the support table, and the material receiving frame and the material feeding frame are both located on the moving path when the moving member drives the support frame to move, and the material receiving frame is used to receive the tested product on the support frame, and the material feeding frame is used to supply the tested product to the empty support frame.

[0016] By adopting the above technical solution, the lifting parts and the moving parts are used to drive the support frame to move back and forth between the receiving frame and the feeding frame, so as to realize automatic and efficient replacement of the tested products and improve the detection efficiency of batch detection.

[0017] Preferably, the driving gear includes a first gear and a second gear, the first gear is meshed with an arc-shaped docking plate, and the second gear is meshed with a driven rack; the first gear sleeve is provided with a first rotating rod, the second gear sleeve is provided with a second rotating rod, and the end of the second rotating rod is provided with a connecting key, and the end of the first rotating rod is provided with a linkage groove for inserting the connecting key, and when the connecting key is inserted into the linkage groove, the first rotating rod and the second rotating rod are coaxially key connected; a limit spring is provided between the connecting key and the inner wall of the linkage groove, and when the limit spring is not deformed, the connecting key is located outside the linkage groove, and at this time, the space between the driven rack and the support plate is greater than the lifting stroke of the lifting member on the product to be tested; and a linkage member is also included, and the linkage member is used to insert the connecting key into the connecting groove.

[0018] By adopting the above technical solution, the connecting key is inserted into the connecting groove by using a linkage part, so that the first rotating rod and the second rotating rod are connected by a coaxial key, so that when the first gear drives the first rotating rod to rotate, the second rotating rod rotates accordingly, and drives the second gear to rotate, and the driven rack to slide. When it is necessary to use the lifting part to remove the tested product on the supporting table, the drive of the connecting key can be released through the linkage part, so that the connecting key is disengaged from the connecting groove under the elastic force of the limit spring. At this time, the second rotating rod slides relative to the first rotating rod, and space is reserved between the driven rack and the supporting table for the tested product to be lifted and moved.

[0019] Preferably, the linkage part includes a linkage rod and a gear set rotatably connected to the support table, and a pressure strip mounted on the linkage rod. The gear set is used to drive the linkage rod to rotate during the rotation of the locking plate, so that the pressure strip rotates toward or away from the second rotating rod, and when the locking plate rotates toward the direction close to the surface of the product to be measured, the gear set is used to drive the linkage rod and the pressure strip to rotate, so that the pressure strip presses the second rotating rod toward the direction close to the second rotating rod, so that the connecting key is inserted into the linkage groove.

[0020] By adopting the above technical scheme, when the locking plate rotates and fits against the surface of the product under test, the gear set is used to drive the linkage rod to rotate with the help of the rotation of the locking plate, so that the pressure bar presses down the second rotating rod, so that the connecting key is inserted into the linkage groove, and the coaxial key connection between the second rotating rod and the first rotating rod is realized; and when the locking plate rotates in a direction away from the product under test to release the positioning of the product under test, the gear set is used to make the pressure bar rotate in a direction away from the second rotating rod with the help of the rotation of the locking plate, thereby pressing the second rotating rod, so that the second rotating rod is disengaged from the connecting groove under the elastic force of the limit spring, so that the second rotating rod and the driven rack move in a direction away from the support plate, thereby freeing up space for the product under test to be lifted and moved.

[0021] Preferably, the support frame is provided with an adsorption member, and the adsorption member is used to adsorb or release the adsorption of the product to be tested on the support frame.

[0022] By adopting the above technical solution, while the support frame is used to support the tested product, the adsorption member is used to stably adsorb the tested product, so as to improve the stability of the tested product during the process of being lifted by the lifting member and the movement of the moving member.

[0023] Preferably, the receiving frame and the feeding frame are rotatably connected with a transmission chain and a driving member for driving the transmission chain to move, the transmission chain is provided with tooth blocks at intervals along its length direction, and a limiting space for inserting a single tested product is reserved between adjacent tooth blocks; it also includes a position detector, and the position detector, the lifting member and the adsorption member are electrically connected to the controller for detecting whether the support frame is inserted into the receiving frame or the feeding frame, and the controller is used to obtain the detection result of the position detector, and control the action of the lifting member, the adsorption member and the driving member based on the detection result.

[0024] By adopting the above technical scheme, for the tested product on the support platen and completed the inspection, the positioning of the tested product is first released by the locking plate, and then the adsorption part is used to adsorb the tested product, and the tested product is driven by the lifting part to move in the direction away from the support platen to a specified lifting stroke, and then the support bracket is driven by the moving part to connect with the tested product to move together and insert it into the receiving frame, so that the tested product is within the limited space. During this process, the position detector detects that the support bracket is inserted into the receiving frame, and the controller controls the adsorption part to release the adsorption of the tested product, controls the lifting part to move in the direction close to the support platen, and then uses the moving part to drive the support bracket and insert it into the feeding frame. After the position detector detects that the support bracket is inserted into the feeding frame, the controller controls the lifting part to move away from the support platen, and controls the adsorption part to start to adsorb the tested product in the feeding frame closest to the support platen, and then uses the moving part to drive the support bracket to move and reset (that is, the limit plate is located outside the support bracket), thereby realizing the operation of automatically replacing the tested product.

[0025] In summary, this application includes the following beneficial technical effects: The product under test is positioned on the support table, and the controller controls the loading and unloading parts to connect the docking plate to the slider, and then the pull rope is pulled by the motor under test, so that the slider drives the docking plate to slide relative to the carrier plate. In this process, the detection module is used to detect the pulling force of the pull rope when the slider slides during the sliding process, as well as the current data input by the power supply to the motor under test to the motor under test. The controller is used to analyze the feedback signal of whether the product under test is qualified based on the above-mentioned detection results. On the one hand, automatic detection of the product under test is realized to improve the detection efficiency.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] Example 1 The present application embodiment discloses a performance detection device for an electric window lifter. Figure 1 and Figure 2 The performance testing device of the electric glass lifter includes a testing platform 1, on which a supporting platform 2 is tiltedly arranged, on which a plurality of locking plates 21 are rotatably connected, and a first rotating member 22 for driving the locking plates 21 to rotate, wherein the first rotating member 22 is specifically a motor, and a gap is reserved between all the locking plates 21 and the supporting platform 2 for inserting a single tested product 5, and when the tested product 5 is placed on the supporting platform 2 and the locking plates 21 are rotated and fitted to the surface of the tested product 5, the tested product 5 will be stably fixed on the supporting platform 2 under the limiting action of the locking plates 21. A detection module 4 and a controller 3 are also provided on the detection platform 1. The detection module 4 and the first rotating member 22 are electrically connected to the controller 3. The detection module 4 is used to detect the product 5 under test, and the detection content at least includes whether the structure of the product 5 under test is complete. The controller 3 is used to obtain and analyze the detection result of the detection module 4, and output a feedback signal for the detection personnel to know based on the analysis result. The feedback signal here is a message used to inform the detection personnel whether the current product 5 under test is a good product or a defective product.

[0035] Reference Figure 1 , Figure 2 and Figure 3Specifically, the product 5 to be tested specifically includes a carrier plate 51, a slider 52, a pull rope 53 and a motor 54 to be tested. The slider 52 is connected to the pull rope 53. The pull rope 53 passes through a fixed pulley preset on the carrier plate 51 and is connected to a driving shaft of the motor 54 to be tested, so that the pull rope 53 is driven by the motor 54 to pull the slider 52, so that the slider 52 slides back and forth along a preset track in the length direction of the carrier plate 51. The test table 1 is also provided with a docking plate 6 and a loading and unloading part 7, and the loading and unloading part 7 includes a support frame 71, a sliding part 72, a lifting part 73, a limiting roller 74 and a limiting rope 75.

[0036] The sliding member 72 and the lifting member 73 are both cylinders. The lifting member 73 is installed on the detection platform 1. The driving end of the lifting member 73 is connected to a support plate. The sliding member 72 is arranged on the support plate. The driving end of the sliding member 72 is connected to the support frame 71. The support frame 71 can slide towards or away from the support platform 2 under the drive of the sliding member 72. The support frame 71 can also slide back and forth in the vertical direction under the drive of the lifting member 73. A receiving groove 711 for inserting the docking plate 6 is provided on the top of the support frame 71. The docking plate 6 is connected to the limiting rope 75. The other end of the limiting rope 75 is wound around the limiting roller 74. The limiting roller 74 is rotatably connected to the detection platform 1. The limiting roller 74 is also sleeved with a torsion spring. One end of the torsion spring is connected to the limiting roller 74, and the other end is connected to the frame. The torsion spring is always in a deformed state. In addition, the sliding path of the slider 52 relative to the carrier plate 51 intersects with the moving path of the docking plate 6 driven by the sliding member 72 and the lifting member 73, that is, the sliding member 72 and the lifting member 73 can cooperate with each other to move the docking plate 6 to overlap the surface of the slider 52, that is, Figure 3 In the state shown, after the docking plate 6 is overlapped on the slider 52, the support frame 71 is disconnected from the docking plate 6 under the drive of the lifting member 73 and the sliding member 72. Thereafter, when the motor 54 under test drives the slider 52 to slide relative to the carrier plate 51, the docking plate 6 will slide with the sliding of the slider 52.

[0037] Correspondingly, the detection module 4 includes a first detection module 41, a second detection module 42, a third detection module 43 and a fourth detection module 44; the first detection module 41 can specifically be a distance measuring sensor arranged on the side wall of each locking plate 21 facing the support table 2. Since the setting position of the locking plate 21 is exactly the position where the carrier 51 is connected with the bolt, that is, when the locking plate 21 is rotated to fit on the carrier 51, the locking plate 21 is fit to the surface of the carrier 51 and the distance measuring sensor is aimed at the bolt hole. Therefore, when the locking plate 21 is rotated to fit on the surface of the product 5 to be tested, the distance measuring sensor is used to detect the distance value between it and the bolt hole, and the controller 3 is used to determine whether a bolt is installed in the bolt hole according to the distance value. Otherwise, it is considered that the structure of the product 5 to be tested is incomplete and the detection result is abnormal.

[0038] The second detection module 42 is specifically a scanner. An identification code is preset on the shell of the motor 54 under test. The second detection module 42 is used to scan the identification code and read the information corresponding to the identification code, that is, the information of the motor 54 under test, and the information of the motor 54 under test at least includes the model of the motor 54 under test. The controller 3 is used to obtain the information of the motor 54 under test and compare and match it with the reference information pre-stored in the database. If the comparison is inconsistent, it is analyzed that the motor 54 under test currently configured by the product 5 under test is not compatible and the detection result is abnormal.

[0039] The third detection module 43 is specifically a pressure sensor. When the product 5 to be tested is positioned on the support table 2 by the locking plate 21 and the docking plate 6 is overlapped on the slider 52, the third detection module 43 is located in the sliding direction of the docking plate 6 when the slider 52 slides along the preset track of the carrier plate 51. The detection table 1 is provided with a cylinder for driving the third detection module 43 to slide in the direction close to or away from the docking plate 6, and when the third detection module 43 moves in the direction close to the docking plate 6, the third detection module 43 can move to the sliding path of the docking plate 6, so that when it conflicts with the docking plate 6, the pressure from the docking plate 6 on the third detection module 43 is detected, thereby characterizing the tension of the pull rope 53, and the pressure obtained by the detection is compared with the preset pressure range. If it is not within the preset pressure range, the detection result is considered to be abnormal.

[0040] In addition, after the product under test 5 is installed on the support table 2, the motor under test 54 will be electrically connected to the preset power supply on the support table 2, and the fourth detection module 44 is used to detect the current data of the predicted power input to the motor under test 54, and the controller 3 is used to obtain the current data and compare it with the preset current range. If the current data exceeds the preset current range, it is considered that the operation of the product under test 5 does not meet the standards and the detection result is abnormal.

[0041] The implementation principle of a performance detection device for an electric glass lifter disclosed in Example 1 of the present application is as follows: a product 5 to be tested is placed on a support table 2, and a distance measuring sensor can be preset to detect whether a product is placed on the support table 2. If so, the controller 3 controls the first rotating member 22 to rotate so that all locking plates 21 are in contact with the surface of the product 5 to be tested, thereby achieving stable fixing of the product 5 to be tested on the support table 2; and during this period, the information of the motor 54 to be tested is identified by the second detection module 42, and whether the structure of the product 5 to be tested is complete is detected by the first detection module 41.

[0042] Then, the tested motor 54 of the tested product 5 is electrically connected to the power supply preset on the support table 2, so that after the tested motor 54 is energized, it drives the slider 52 to slide to the specified position and then turns off the power so as to dock with the docking plate 6. A distance measuring sensor can also be preset on the support table 2 to detect whether the slider 52 slides to the specified position. If so, the controller 3 first controls the lifting member 73 to start driving the support frame 71 and the docking plate 6 to move upward, and then controls the sliding member 72 to drive the docking plate 6 to move in the direction close to the upper surface of the slider 52, and finally moves the docking plate 6 to the upper surface of the slider 52; then, the sliding member 72 and the lifting member 73 drive the support frame 71 to move and detach from the docking plate 6, and then the docking plate 6 is moved to the upper surface of the slider 52. During this process, lubricant can be applied on the preset track of the carrier plate 51 to reduce the resistance of the preset track to the sliding of the slider 52. Finally, the power supply is started again so that the motor 54 under test drives the slider 52 and the docking plate 6 to slide along the preset track, and during this period, the current data input to the motor 54 under test is obtained in real time through the fourth module; a distance sensor can be set above the support table 2 to detect the distance between the docking plate 6 and the distance sensor. When the distance reaches a specified value and gradually decreases, the controller 3 controls the third detection module 43 to move toward the sliding path of the docking plate 6 in the direction close to the slider 52, and obtains the pressure from the docking plate 6 when it contacts the docking plate 6. The controller 3 analyzes the detection results obtained by the detection module 4 and obtains the analysis results, and uses the pre-connected display screen to display the feedback signal, which is used to reflect whether the detection results of each detection content of the detection module 4 are abnormal.

[0043] Example 2 The difference between Example 2 of the present application and Example 1 is that: Figure 2 , Figure 4 and Figure 5 , support plate 2 according to Figure 4 The direction indicated by the dotted arrow is reciprocatingly connected to the detection platform 1, and Figure 3 The angle shown is the initial angle when the support plate 2 is not rotated, that is, Figure 4The support plate 2 is shown in an initial position. A second rotating member 11 is mounted on the testing platform 1 for driving the support plate 2 to rotate. The second rotating member 11 is specifically a motor. A plurality of tilting points are provided on the testing platform 1, and the tilting points are located on the moving path of the slider 52 of the tested product 5 on the supporting table 2 when it slides relative to the carrier plate 51 and moves with the rotation of the supporting table 2; the moving path of the slider 52 disclosed in the embodiment of the present application is specifically as follows: when the supporting table 2 is in the initial position, the slider 52 moves a specified length in the direction close to the third detection module 43 and then stops, and the stop position is the first tilting point, then the supporting table 2 rotates a specified angle in the direction away from the support frame 71 and stops, at this time the angle between the supporting table 2 and the testing platform 1 becomes smaller, and then the slider 52 continues to move a specified length in the direction close to the third detection module 43 on the supporting table 2 in the current tilted state and then stops, and the stop position is the second tilting point, and then the above operation is repeated, that is, each time the supporting table 2 rotates a specified angle, the slider 52 moves a specified length on the rotated supporting table 2, so as to detect the change in the tension of the pull rope 53 on the slider 52 when the slider 52 slides on the supporting table 2 in the corresponding tilted state.

[0044] Correspondingly, the third detection module 43 of the present application is specifically connected to a driven rack 23, which is slidably connected to the support table 2 along the support table 2, and the sliding direction is parallel to the sliding direction of the slider 52 contained in the tested product 5 on the support table 2 when it slides along the preset track; the support table 2 is also rotatably connected to a first rotating rod 24 and a second rotating rod 25, and the support table 2 is also rotatably connected to an active gear, which includes a first gear 26 and a second gear 27. The first gear 26 is fixedly sleeved on the first rotating rod 24, and an arc-shaped docking plate 28 is provided on the support table 2. The side wall of the arc-shaped docking plate 28 is provided with a tooth groove along its curvature direction. When the first gear 26 rotates with the rotation of the support plate, the first gear 26 is always meshed with the tooth groove on the arc-shaped docking plate 28, and drives the first rotating rod 24 to realize self-rotation under the transmission action of the tooth groove.

[0045] A connecting key 251 is provided at one end of the second rotating rod 25 near the first rotating rod 24. A linkage groove 241 is provided on the end wall of the first rotating rod 24 for inserting the connecting key 251. A limit spring is connected between the bottom wall of the linkage groove 241 and the connecting key 251. When the connecting key 251 is inserted into the linkage groove 241, the second rotating rod 25 is coaxially key-connected with the first rotating rod 24 (i.e. Figure 5), at this time, the second rotating rod 25 will rotate with the first rotating rod 24 when the first rotating rod 24 rotates. The second gear 27 is fixedly sleeved on the outside of the second rotating rod 25, and the second gear 27 is always meshed with the driven rack 23, that is, when the support plate 2 rotates, the driven rack 23 will drive the third detection module 43 to slide under the transmission action of the first gear 26, the second gear 27, and the arc-shaped docking plate 28. After the support plate 2 stops rotating, the third detection module 43 just moves to the corresponding tilting point, so as to detect the pressure of the docking plate 6 when the slider 52 and the docking plate 6 slide to the corresponding tilting point.

[0046] Correspondingly, a linkage member 29 is provided near the second rotating rod 25 of the support table 2, and the linkage member 29 includes a linkage rod 291 and a gear set 292. The linkage rod 291 is rotatably connected to the side wall of the support table 2 near the second rotating rod 25, and a pressure strip 293 is fixedly sleeved on the linkage rod 291. The pressure strip 293 is used to move toward or away from the second rotating rod 25 during the rotation of the linkage rod 291, and when approaching the second rotating rod 25, press the second rotating rod 25 so that the connecting key 251 of the second rotating rod 25 is inserted into the linkage groove 241, and when away from the second rotating rod 25, release the pressure on the second rotating rod 25 so that the connecting key 251 moves to the periphery of the linkage groove 241 under the elastic force of the limit spring.

[0047] The gear set 292 includes two gears meshing with each other, one of which is sleeved on the linkage rod 291, and the other is sleeved on the driving shaft of the first rotating member 22 corresponding to the locking plate 21 closest to the second rotating rod 25; so that when the first rotating member 22 drives the corresponding locking plate 21 to rotate to fit the surface of the product 5 to be tested, the pressing bar 293 presses the second rotating rod 25 under the drive of the gear set 292, and inserts the connecting key 251 into the linkage groove 241, so as to realize the coaxial key connection between the second rotating rod 25 and the first rotating rod 24, so that the second rotating rod 25 can subsequently rotate with the rotation of the first rotating rod 24. When the first rotating member 22 drives the locking plate 21 to rotate and disengage from the product 5 under test, the pressure bar 293 will release the pressure on the second rotating rod 25 under the drive of the gear group 292, so that the second rotating rod 25 moves in the direction away from the support table 2 under the drive of the limit spring, thereby causing the driven rack 23 and the third detection module 43 to move in the direction away from the support table 2 (the moving direction is parallel to the thickness direction of the support table 2), thereby increasing the space (hereinafter referred to as space A) between the driven rack 23 and the support table 2, that is, the distance d shown in the figure, so that the product 5 under test that has completed the inspection can be separated from the contact with the support table 2 and can be smoothly taken out from the space A.

[0048] Reference Figure 4 , Figure 5 and Figure 6A support frame 12 for placing the tested product 5 is provided on the support plate 2, and a protrusion is provided on the side of the carrier plate 51 of the tested product 5 away from the support frame 71, and the protrusion is inserted into the support frame 12 to achieve the overlap between the support frame 12 and the tested product 5; and a suction piece 13 is also provided on the side of the support frame 12 facing the tested product 5, and the suction piece 13 is used to fix the tested product 5 on the support frame 12 in a vacuum suction manner, and a moving piece 14 is provided on the side of the support frame 12 away from the suction piece 13, and the moving piece 14 specifically includes a moving track, a moving block inserted in the moving track, and a moving block for driving the moving block to slide along the length direction of the moving track. The motor-screw combination structure has a moving track length parallel to the width direction of the support table 2, the moving block is connected to the side of the support bracket 12 away from the adsorption member 13, and the side wall of the moving track away from the support bracket 12 is connected with a lifting member 15, the lifting member 15 is installed on the support table 2, and the lifting member 15 can specifically be a cylinder, the lifting member 15 is used to drive the support bracket 12 to move, so that the product 5 under test moves in the space A, toward or away from the support table 2, and when it moves toward the direction close to the support table 2 and fits against the support table 2, the locking plate 21 can just rotate and fit against the side surface of the product 5 under test away from the support table 2.

[0049] The testing platform 1 is also provided with a receiving frame 8 and a feeding frame 9, which are respectively located at the two ends of the length direction of the moving track, and the support bracket 12 can be moved and inserted into the receiving frame 8 or the feeding frame 9 under the drive of the moving member 14. Specifically, the receiving frame 8 and the feeding frame 9 are both connected to the transmission chain 81 and the driving member 82 for driving the transmission chain 81 to move. The driving member 82 is specifically a sprocket connected to the transmission chain 81 and a motor for driving the sprocket to rotate. The transmission chain 81 is integrally formed with tooth blocks 811 at intervals along its length direction, and a limit space 83 is reserved between adjacent tooth blocks 811 for inserting a single product 5 to be tested. Position sensors are respectively provided at the receiving frame 8 and the feeding frame 9 to detect whether the support bracket 12 is inserted into the receiving frame 8 or the feeding frame 9. Specifically, the position sensor can be a ranging sensor arranged on the moving track near the receiving frame 8 and the feeding frame 9. The moving position of the support bracket 12 relative to the moving track is determined by detecting the distance value between it and the support bracket 12, thereby determining whether the support bracket 12 is inserted into the receiving frame 8 or the feeding frame 9.

[0050] The moving trajectory of the support frame 12 is as follows: after the product 5 to be tested on the support plate 2 is tested, the locking plate 21 releases the limit on the product 5 to be tested, and the lifting member 15 drives the support frame 12 and the product 5 to move a certain distance away from the support plate 2, and then the moving member 14 drives the support frame 12 and the product 5 to move and insert them into the receiving frame 8 through the preset notch preset at the side wall of the receiving frame 8, and there is a limit space 83 in the receiving frame 8 located on the moving insertion path of the product 5 to be tested, so that the product 5 to be tested can be smoothly inserted into the limit space 83 when inserted into the receiving frame 8. At this time, the position sensor located at the receiving frame 8 When the device detects that the support frame 12 is inserted into the material receiving frame 8, the controller 3 controls the adsorption member 13 to release the adsorption of the tested product 5 and controls the lifting member 15 to move in the direction close to the support table 2 (i.e., move in the direction away from the material receiving frame 8), so that the support frame 12 is separated from the tested product 5. At the same time, the controller 3 controls the driving member 82 to drive the transmission chain 81 to move (move in the direction indicated by the arrow C) a specified distance (i.e., the width of a limit space 83), so that the limit space 83 adjacent to the limit space 83 where the tested product 5 is located and the vacant limit space 83 is transferred to the preset gap of the material receiving frame 8, waiting to receive the next tested product 5 that has completed the inspection.

[0051] Then the moving part 14 drives the empty support frame 12 and inserts it into the feed frame 9. At this time, the position sensor located at the feed frame 9 detects that the support frame 12 is inserted into the feed frame 9. The controller 3 will first control the lifting part 15 to move in the direction away from the support table 2 (that is, move in the direction close to the feed frame 9) so that the adsorption part 13 is attached to the surface of the tested product 5 located at the preset notch of the feed frame 9, and then control the adsorption part 13 to adsorb the tested product 5. Then, the moving part 14 is used to drive the support frame 12 and the tested product 5 to pass through the preset notch and move into the space A. Finally, the controller 3 controls the transmission chain 81 at the feed frame 9 to move (move in the direction shown by the arrow D) a specified distance, so that the limit space 83 corresponding to the currently taken out tested product 5 and the limit space 83 device with the tested product 5 inserted is located at the preset notch of the feed frame 9.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
