Description

Technical Field

[0001] This invention relates to the field of inspection equipment technology, specifically a lifting and floating platform for AC inspection. Background Technology

[0002] New energy electric drive systems mainly include core components such as drive motors, motor controllers, battery packs, and energy management systems, supplemented by transmission devices and control systems to achieve power output and energy management. After these structures are manufactured, each component needs to undergo quality inspection. For example, after the housings of components such as drive motors and battery packs are manufactured, their appearance and welding quality need to be inspected to ensure the quality of subsequent finished products. Existing inspection methods can automatically identify defects such as scratches, dents, and protrusions on the product surface using high-resolution cameras and AI algorithms, or use high-precision 3D laser profilometers to scan and acquire three-dimensional surface data to detect defects such as scratches, dents, and protrusions, thereby achieving rapid and accurate quality inspection of some components to be inspected in the electric drive system.

[0003] During the inspection of these components, the components to be inspected must first be transported to a lifting floating platform using handling equipment. The lifting floating platform then moves the components to a suitable position for inspection. However, existing lifting floating platforms are prone to swaying during the upward movement of components, leading to component displacement or detachment, affecting the accuracy of subsequent inspections. Furthermore, during the transfer of components to the lifting floating platform using handling equipment, it is difficult to accurately place them on top of the platform, causing component displacement. This can result in components falling or shifting during subsequent upward movement, thus affecting normal inspection. Summary of the Invention

The lower end of the air cylinder is open and has an external thread. A sealing cap is fixedly installed at the lower end of the air cylinder. A polygonal plug rod is slidably inserted through the lower end of the sealing cap from bottom to top. The upper end of the polygonal plug rod extends into the inner cavity of the air cylinder and is fixedly connected to a piston. The piston slides in contact with the inner wall of the air cylinder.

[0012] The upper end of the bearing plate has symmetrical through holes on the left and right. The lower end of the polygonal plug rod extends downward to the through hole and is fixedly connected to a pulley frame. The lower end of the pulley frame is equipped with a positioning pulley that rotates through a round shaft. A push spring is sleeved on the polygonal plug rod, and the two ends of the push spring abut against the sealing cover and the pulley frame, respectively.

[0013] As a further embodiment of the present invention, the adsorption assembly includes a main air pipe fixedly inserted into the upper end of the air cylinder, a branch air pipe symmetrically fixedly inserted into the end of the main air pipe away from the air cylinder, the end of the branch air pipe away from the main air pipe penetrating from bottom to top and inserted into the upper end of the fixed frame, and a suction cup fixedly installed at the end of the branch air pipe above the fixed frame, the suction cup being fixedly installed at the upper end of the fixed frame.

[0014] As a further embodiment of the present invention, the clamping mechanism includes a hydraulic cylinder fixedly installed on the upper end of the lifting seat, a clamping plate fixedly installed on the end of the inner rod of the hydraulic cylinder, and detection mechanisms for the position of the bearing plate symmetrically installed at the front and rear ends of the clamping plate.

[0015] As a further embodiment of the present invention, the detection mechanism includes a positioning plate fixedly installed at the end of the clamping plate. A concave seat is fixedly connected to the upper end of the positioning plate. A lifting groove is opened through the lower end of the concave seat. A T-shaped block is slidably installed inside the concave seat. The lower end of the T-shaped block passes downward through the lifting groove and extends to the outside. A pressing slope is opened at the lower end of the T-shaped block on the side near the bearing plate. A guide light rod is symmetrically fixedly connected to the upper end of the T-shaped block. A reset spring is sleeved on the guide light rod. The upper end of the guide light rod passes upward through the upper end of the concave seat. The guide light rod and the concave seat are slidably connected vertically. A triggering mechanism is installed at the upper end of the concave seat.

[0016] As a further embodiment of the present invention, the triggering mechanism includes a slide rod that extends downwards and is inserted through the upper end of a concave seat. The slide rod is slidably connected to the concave seat. A buffer spring is sleeved on one end of the slide rod inside the concave seat. A connecting block is fixedly connected to the lower end of the slide rod. A second electrode plate is fixedly installed on the lower end of the connecting block. A limit ring is fixedly sleeved on the upper end of the slide rod. A first electrode plate is fixedly installed on the upper end of the T-shaped block below the second electrode plate. An indicator light and a battery body are fixedly installed on the side of the concave seat.

[0017] The beneficial effects of this invention are:

[0018] 1. Place the housing to be tested on top of the support plate, and connect the mounting holes on the bottom of the housing to the adjacent second positioning plugs to complete the positioning of the housing to be tested. When the middle position of the support plate is not in contact with other components, the adsorption fixing mechanism adsorbs and fixes the housing to be tested, thus firmly installing the housing to be tested on top of the support plate. Through the combination of the adsorption fixing mechanism, mounting holes, and second positioning plugs, the housing to be tested can be firmly positioned, ensuring that the housing to be tested is firmly on top of the support plate, preventing the housing to be tested from shaking or falling during movement and transportation, and ensuring the accuracy of subsequent inspections.

[0019] 2. When the support plate is placed above the lifting seat, the lifting transmission mechanism drives the lifting seat to move upward a certain distance, allowing the first positioning plug to engage with the docking sleeve, thus completing the initial positioning of the support plate. If the position of the support plate is deviated, preventing the first positioning plug from accurately engaging with the docking sleeve, the first positioning plug supports the support plate, preventing the lower end of the support plate from contacting the upper end of the lifting seat. At this time, during the clamping process of the clamping mechanism, the clamping plate drives the detection mechanism and the triggering mechanism to move closer to the support plate. The support plate pushes the T-shaped block to slide upward along the lifting groove, activating the triggering mechanism. At this time, the circuit is closed and energized, illuminating the indicator light, thereby reminding the staff that the position of the support plate is abnormal, allowing the staff to make timely adjustments or stop subsequent processes, and continue working after adjustment.

[0020] 3. The lifting transmission mechanism continues to drive the lifting seat upward. When the middle position of the bearing plate does not contact other parts, the adsorption and fixing mechanism adsorbs and fixes the shell to be tested. As the lifting seat drives the shell to be tested to continue to move upward through the bearing plate, the shell to be tested can be firmly placed above the bearing plate without shaking, misalignment or falling, until it moves to the appropriate position, thereby performing the inspection operation on the shell to be tested, which greatly improves the accuracy of the inspection.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 11 The present invention provides a technical solution: a lifting floating platform for AC inspection, including a support base 1, a lifting transmission mechanism installed on the inner side of the support base 1, a lifting seat 3 symmetrically installed on the upper end of the lifting transmission mechanism, a first positioning seat 31 symmetrically installed on the upper end of the lifting seat 3, a first positioning plug 32 fixedly connected to the upper end of the first positioning seat 31, a bearing plate 4 placed on the upper end of the two lifting seats 3, a docking sleeve 41 symmetrically installed from top to bottom on the upper end of the bearing plate 4, the number of docking sleeves 41 being the same as the number of first positioning plugs 32, an insertion hole matching the first positioning plug 32 being opened on the inner side of the docking sleeve 41, the first positioning plug 32 being movably inserted into the adjacent docking sleeve 41, and the lower end of the bearing plate 4 contacting the upper end of the two lifting seats 3;

[0035] Multiple second positioning seats 42 are fixedly installed on the upper end of the support plate 4. The second positioning seats 42 are detachably connected to the support plate 4. A second positioning plug 43 is fixedly connected to the upper end of the second positioning seat 42. A housing 44 to be tested is installed on the upper end of the second positioning seat 42. The housing 44 to be tested can be replaced with other components of the new energy electric drive system. Multiple mounting holes 45 are opened at the lower end of the housing 44 to be tested. The second positioning plug 43 is movably inserted into the adjacent mounting holes 45. An adsorption fixing mechanism is installed on the support plate 4 at the lower end of the housing 44 to be tested. Clamping mechanisms are symmetrically installed on the upper ends of the two lifting seats 3. The two clamping mechanisms are symmetrically distributed on both sides of the support plate 4.

[0036] When installing the housing 44 to be tested, place the housing 44 to be tested on top of the support plate 4, so that the mounting holes 45 on the bottom of the housing 44 to be tested are respectively connected to the second positioning plugs 43 on the upper end of the adjacent second positioning seat 42, thereby completing the positioning of the housing 44 to be tested.

[0037] When there are no other parts supporting the middle position of the support plate 4, that is, when the middle position of the support plate 4 is not in contact with other parts, the adsorption and fixing mechanism adsorbs and fixes the housing 44 to be tested, so that the housing 44 to be tested is firmly installed on the top of the support plate 4.

[0038] During operation, the carrier plate 4 and the housing 44 to be tested are moved above the two lifting seats 3 by the handling equipment. At this time, the two lifting seats 3 are at the bottom. Then, by moving the two lifting seats 3 upward, the lifting seats 3 move upward through the first positioning seat 31. The first positioning seat 31 drives the first positioning plug 32 to be inserted into the adjacent docking sleeve 41, thereby completing the initial positioning of the carrier plate 4.

[0039] Please see Figure 1 and Figure 2The lifting transmission mechanism includes a lifting plate 11 that can move up and down and is installed inside the support base 1. A threaded sleeve 12 is fixedly installed through one end of the lifting plate 11. A lead screw 13 is inserted through the inner side of the threaded sleeve 12 and threadedly connected to the threaded sleeve 12. Both the upper and lower ends of the lead screw 13 are rotatably connected to the support base 1 through bearing seats. A transmission toothed pulley 14 is fixedly sleeved on the upper end of the lead screw 13. A drive toothed pulley 15 is rotatably installed on the upper end of the support base 1. A connecting toothed belt 16 is sleeved on the outer side of the transmission toothed pulley 14 and the drive toothed pulley 15. The connecting toothed belt 16 is connected to the transmission toothed pulley 14 and the drive toothed pulley 15 respectively. The drive toothed pulley 14 and the drive toothed pulley 15 mesh with the active toothed pulley 15. They are located at both ends of the connecting toothed belt 16. The active toothed pulley 15 is driven by the motor shaft of a stepper motor fixedly installed in the support base 1. The motor shaft is connected to the active toothed pulley 15 via a coupling or flange. Sliding sleeves 17 are symmetrically fixedly connected to the left and right sides of the upper end of the support base 1. A support rod 18 is slidably inserted into the inner side of each sliding sleeve 17. The lower end of the support rod 18 is fixedly connected to the upper end of the lifting plate 11, and a connecting seat 2 is fixedly connected to the upper end of the support rod 18. The connecting seat 2 is fixedly connected to the lifting base 3. The support rods 18 on the left and right sides of the lifting plate 11 are respectively located below the two lifting bases 3.

[0040] A protective shell is fitted over the transmission toothed pulley 14, the drive toothed pulley 15 and the connecting toothed belt 16, and the protective shell is fixedly installed on the upper end of the support base 1.

[0041] By rotating the motor shaft of the stepper motor forward or backward, the motor shaft drives the drive toothed pulley 15 to rotate forward or backward. The drive toothed pulley 15 drives the transmission toothed pulley 14 to rotate forward or backward through the connecting toothed belt 16. The transmission toothed pulley 14 drives the lead screw 13 to rotate forward or backward. Through the lead screw 13, the threaded sleeve 12 and the lifting plate 11 move up and down. The lifting plate 11 drives the support rod 18 to slide up and down along the sliding sleeve 17. The support rod 18 drives the lifting seat 3 to move up and down through the connecting seat 2.

[0042] The lifting seat 3 moves the housing 44 to be inspected up and down through the bearing plate 4, adjusting the position of the housing 44 to be inspected. When the lifting seat 3 is at its lowest position, the bearing plate 4 and the housing 44 to be inspected are moved above the lifting seat 3 or removed by the handling equipment to complete the loading or unloading. The lifting seat 3 moves upward, causing the bearing plate 4 to move the housing 44 to be inspected upward, waiting for quality inspection.

[0043] Please see Figure 11 The lower end of the connector 2 is provided with a circular slot, the side of the connector 2 is provided with a semi-circular groove 21, the lower end of the semi-circular groove 21 is provided with a notch 22 extending downwards, the inner side of the circular slot is provided with a compensation groove 23, the side of the connector 2 is threaded with a locking screw, the locking screw passes through the notch 22, and the upper end of the support rod 18 is inserted into the circular slot.

[0044] When assembling the support rod 18 and the connecting seat 2, first insert the support rod 18 into the circular slot. By screwing the locking screw into the connecting seat 2, the two inner sidewalls of the side notch 22 of the connecting seat 2 are brought closer together, thereby tightening the lower end of the connecting seat 2 and firmly locking the connecting seat 2 into the upper end of the support rod 18, thus completing the installation of the support rod 18 and the connecting seat 2. When disassembling, unscrew the locking screw from the connecting seat 2. At this time, the connecting seat 2 is loosened from the locking of the support rod 18, and the support rod 18 can be removed from the circular slot.

[0045] Please see Figure 6 The bearing plate 4 has recessed grooves at both the front and rear ends on both sides of the left and right sides, that is, recessed grooves are provided at the four corners of the bearing plate 4. A fixing plate 48 is installed at the upper end of each recessed groove by screws, and a guide wheel 49 is installed at the lower end of the fixing plate 48 by bolts and nuts.

[0046] The guide wheel 49 is rotatably sleeved on the rotating shaft via a bearing. The upper end of the rotating shaft is integrally formed or fixedly connected with a bolt. The rotating shaft is fixedly installed on the fixed plate 48. Through the guide wheel 49, the bearing plate 4 is guided to move during the transmission process, preventing collisions between the bearing plate 4 and the transmission equipment.

[0047] Please see Figures 6 to 8 The adsorption fixing mechanism includes a fixing frame 46 fixedly installed on the upper end of the support plate 4. Suction mechanisms are fixedly installed on the left and right sides of the fixing frame 46. An adsorption component is installed at one end of the suction mechanism. When the shell to be tested 44 is installed above the support plate 4, the upper end of the adsorption component contacts the lower end of the shell to be tested 44. The lower end of the shell to be tested 44 is a smooth surface.

[0048] The suction mechanism includes an air cylinder 5 that is fixedly installed on the upper end of the fixed frame 46 from top to bottom. The lower end of the air cylinder 5 is open and has an external thread. A sealing cap 51 is fixedly installed on the lower end of the air cylinder 5. A polygonal plug rod 52 is slidably inserted through the lower end of the sealing cap 51 from bottom to top. The upper end of the polygonal plug rod 52 extends into the inner cavity of the air cylinder 5 and is fixedly connected to a piston 53. The piston 53 slides in contact with the inner cavity sidewall of the air cylinder 5.

[0049] The upper end of the bearing plate 4 is symmetrically provided with through holes 47. The lower end of the polygonal plug rod 52 extends downward to the through hole 47 and is fixedly connected to the pulley frame 54. The lower end of the pulley frame 54 is rotatably mounted with a positioning pulley 55 through a round shaft. A push spring 56 is sleeved on the polygonal plug rod 52. The two ends of the push spring 56 abut against the sealing cover 51 and the pulley frame 54 respectively. The push spring 56 applies a downward elastic force to the pulley frame 54.

[0050] The maximum width or maximum diameter of the pulley bracket 54 is smaller than the diameter of the through hole 47, so that the pulley bracket 54 can move up and down along the through hole 47. In the initial state, the bottom of the positioning pulley 55 is below the bearing plate 4.

[0051] The adsorption assembly includes a main air pipe 6 fixedly inserted into the upper end of the air cylinder 5. The main air pipe 6 is a bent pipe, and the inner cavity of the main air pipe 6 is connected to the inner cavity of the air cylinder 5. A branch pipe 61 is symmetrically fixedly inserted into the end of the main air pipe 6 away from the air cylinder 5. The inner cavity of the branch pipe 61 is connected to the inner cavity of the main air pipe 6. The end of the branch pipe 61 away from the main air pipe 6 passes through and is inserted into the upper end of the fixing frame 46 from bottom to top. A suction cup 62 is fixedly installed at the end of the branch pipe 61 above the fixing frame 46. The inner cavity of the suction cup 62 is connected to the inner cavity of the branch pipe 61. The suction cup 62 is fixedly installed at the upper end of the fixing frame 46.

[0052] When the housing 44 to be tested is installed on the upper end of the support plate 4, the lower end of the housing 44 to be tested contacts the upper end of the suction cup 62, that is, the opening of the suction cup 62 is in close contact with the lower end of the housing 44 to be tested.

[0053] When the middle position of the bearing plate 4 is not in contact with other components, there is no object or obstruction below the positioning pulley 55. Under the action of the spring force of the push spring 56, the pulley frame 54 and the positioning pulley 55 move downward. The pulley frame 54 drives the polygonal plug rod 52 to slide downward along the sealing cover 51, so that the polygonal plug rod 52 moves outward from the inner cavity of the air cylinder 5.

[0054] The polygonal stopper 52 drives the piston 53 to slide downwards. At this time, the piston 53 draws the gas from the main air pipe 6, the branch air pipe 61 and the suction cup 62 into the inner cavity of the air cylinder 5, thereby creating a negative pressure in the suction cup 62. This causes the suction cup 62 to firmly adhere to and fix the lower end of the housing 44 to be tested, preventing the housing 44 to be tested from shaking up and down. This allows the inspection equipment to accurately inspect the housing 44 to be tested, ensuring the accuracy of the inspection.

[0055] When the middle position of the support plate 4 comes into contact with other components, during the contact process, the other components will squeeze the pulley frame 54 and the positioning pulley 55, causing the pulley frame 54 and the positioning pulley 55 to move into the through hole 47. At this time, the pulley frame 54 drives the polygonal plug rod 52 to slide upward along the sealing cover 51. The polygonal plug rod 52 is inserted into the inner cavity of the air cylinder 5. At the same time, the polygonal plug rod 52 drives the piston 53 to move upward along the inner cavity of the air cylinder 5. At this time, the gas in the inner cavity of the air cylinder 5 is squeezed out, and the gas enters the suction cup 62 along the main air pipe 6 and the branch air pipe 61. The suction cup 62 releases the adsorption and fixation of the housing 44 to be tested, so that the housing 44 to be tested can be moved upward along the support plate 4, and the disassembly of the housing 44 to be tested can be completed.

[0056] Please see Figure 3 , Figure 9 and Figure 10 The clamping mechanism includes a hydraulic cylinder 7 fixedly installed on the upper end of the lifting seat 3. A clamping plate 71 is fixedly installed on the end of the inner rod of the hydraulic cylinder 7. Detection mechanisms for the position of the bearing plate 4 are symmetrically installed at the front and rear ends of the clamping plate 71.

[0057] Two hydraulic cylinders 7 control the direction and flow of liquid through a hydraulic system, ensuring that multiple hydraulic cylinders 7 expand and contract with the same speed and force.

[0058] The displacement sensor and control system monitor the motion status of each cylinder in real time and make adjustments as needed to achieve precise synchronization of the displacement between the hydraulic cylinders 7. The movement commands of the two hydraulic cylinders 7 are adjusted to achieve synchronous extension and retraction of the two hydraulic cylinders 7.

[0059] The inner rods of the two hydraulic cylinders 7 extend to bring the two clamping plates 71 closer together. The two clamping plates 71 are respectively clamped on the left and right sides of the support plate 4, thereby clamping and fixing the support plate 4 and preventing it from shaking during the up and down movement of the floating platform.

[0060] Please see Figure 9 and Figure 10 The detection mechanism includes a positioning plate 72 fixedly installed at the end of the clamping plate 71. A concave seat 73 is fixedly connected to the upper end of the positioning plate 72. A lifting groove 74 is opened through the lower end of the concave seat 73. A T-shaped block 8 is slidably installed inside the concave seat 73. The lower end of the T-shaped block 8 passes downward through the lifting groove 74 and extends to the outside. A pressing slope 81 is opened at the lower end of the T-shaped block 8 near the bearing plate 4. A guide light rod 82 is symmetrically fixedly connected to the upper end of the T-shaped block 8. A return spring 83 is sleeved on the guide light rod 82. The upper end of the guide light rod 82 passes upward through the upper end of the concave seat 73. The guide light rod 82 and the concave seat 73 are slidably connected up and down. The two ends of the return spring 83 abut against the T-shaped block 8 and the concave seat 73 respectively. The return spring 83 applies a downward elastic force to the T-shaped block 8. A triggering mechanism is installed at the upper end of the concave seat 73.

[0061] The triggering mechanism includes a slide rod 9 that extends downwards and is inserted into the upper end of a concave seat 73. The slide rod 9 is slidably connected to the concave seat 73. A buffer spring 91 is sleeved on one end of the slide rod 9 inside the concave seat 73. A connecting block 92 is fixedly connected to the lower end of the slide rod 9. The two ends of the buffer spring 91 abut against the concave seat 73 and the connecting block 92, respectively. The buffer spring 91 applies a downward elastic force to the connecting block 92. A second electrode plate 93 is fixedly installed on the lower end of the connecting block 92. A limit ring 94 is fixedly sleeved on the upper end of the slide rod 9. A first electrode plate 84 is fixedly installed on the upper end of the T-shaped block 8 below the second electrode plate 93. An indicator light 95 and a battery body 96 are fixedly installed on the side of the concave seat 73.

[0062] An indicator light 95 and a battery body 96 are connected in series between the first electrode plate 84 and the second electrode plate 93. Specifically, the first electrode plate 84 is connected to one terminal of the battery body 96 via a wire, the other terminal of the battery body 96 is connected to one terminal of the indicator light 95 via a wire, and the other terminal of the indicator light 95 is connected to the second electrode plate 93 via a wire. When the first electrode plate 84 and the second electrode plate 93 are in contact, the circuit is closed, and the indicator light 95 is energized. When the first electrode plate 84 and the second electrode plate 93 are separated, the circuit is open, and the indicator light 95 is not energized.

[0063] Under normal circumstances, the first positioning plug 32 is inserted into the docking sleeve 41. At this time, when the clamping mechanism clamps the carrier plate 4, the detection mechanism and the triggering mechanism move above the carrier plate 4. At this time, the T-shaped block 8 in the detection mechanism will not contact the carrier plate 4, that is, it will not cause the triggering mechanism to start.

[0064] During the handling of the bearing plate 4, if the position of the bearing plate 4 is inaccurate, the first positioning plug 32 and the docking sleeve 41 cannot be accurately inserted during the docking process of the lifting seat 3 and the bearing plate 4. At this time, the first positioning plug 32 supports the bearing plate 4, so that the lower end of the bearing plate 4 cannot contact the upper end of the lifting seat 3.

[0065] During the clamping process of the clamping mechanism clamping the carrier plate 4, the clamping plate 71 drives the detection mechanism and the triggering mechanism to move closer to the carrier plate 4. At this time, the pressing inclined surface 81 of the T-shaped block 8 first contacts the carrier plate 4. When the detection mechanism and the triggering mechanism continue to move closer to the carrier plate 4, the carrier plate 4 pushes the T-shaped block 8 to slide upward along the lifting groove 74. At this time, the T-shaped block 8 drives the guide light rod 82 and the first electrode plate 84 to move upward. The guide light rod 82 slides along the concave seat 73, and the T-shaped block 8 presses the reset spring 83.

[0066] When the T-shaped block 8 moves upward a certain distance, the first electrode plate 84 comes into contact with the second electrode plate 93. At this time, the circuit is closed and energized, causing the indicator light 95 to light up, thereby reminding the staff that the position of the carrier plate 4 is abnormal.

[0067] Working principle: During operation, the housing 44 to be tested is placed above the support plate 4, and the mounting holes 45 on the bottom of the housing 44 to be tested are respectively connected to the second positioning plugs 43 on the upper end of the adjacent second positioning seat 42, thereby completing the positioning of the housing 44 to be tested. At this time, the lower end of the housing 44 to be tested is in contact with the upper end of the suction cup 62.

[0068] When the middle position of the support plate 4 is in contact with other components, the adsorption and fixing mechanism will not adsorb and fix the housing 44 to be tested; when the middle position of the support plate 4 is not in contact with other components, the adsorption and fixing mechanism will adsorb and fix the housing 44 to be tested, so that the housing 44 to be tested is firmly installed on the support plate 4.

[0069] By using the adsorption fixing mechanism, mounting hole 45 and second positioning plug 43, the housing 44 to be tested can be firmly positioned, so that the housing 44 to be tested can be firmly placed above the support plate 4, preventing the housing 44 to be tested from shaking or falling during movement and transportation, and ensuring the accuracy of subsequent inspection.

[0070] The carrier plate 4 is moved by transmission equipment or robotic arm to the top of the lifting seat 3. The lifting transmission mechanism drives the lifting seat 3 to move upward a certain distance so that the first positioning plug 32 is inserted into the docking sleeve 41, completing the initial positioning of the carrier plate 4. At this time, the transmission mechanism or robotic arm is removed, and the carrier plate 4 is clamped and positioned by the clamping mechanism.

[0071] If the position of the support plate 4 is deviated, the first positioning plug 32 and the docking sleeve 41 cannot be accurately inserted. The support plate 4 is supported by the first positioning plug 32, so that the lower end of the support plate 4 cannot contact the upper end of the lifting seat 3.

[0072] During the clamping process of the clamping mechanism clamping the carrier plate 4, the clamping plate 71 drives the detection mechanism and the triggering mechanism to move closer to the carrier plate 4. The carrier plate 4 pushes the T-shaped block 8 to slide upward along the lifting groove 74, which activates the triggering mechanism. That is, the first electrode plate 84 contacts the second electrode plate 93. At this time, the circuit is closed and energized, causing the indicator light 95 to light up, thereby reminding the staff that the position of the carrier plate 4 is abnormal, allowing the staff to make timely adjustments or stop the subsequent process and continue working after adjustment.

[0073] The lifting transmission mechanism continues to move the lifting seat 3 upwards. When the middle position of the bearing plate 4 is no longer in contact with other components, the adsorption and fixing mechanism adsorbs and fixes the housing 44 to be inspected. As the lifting seat 3 continues to move the housing 44 upwards via the bearing plate 4, the housing 44 remains firmly positioned above the bearing plate 4, without shaking, misalignment, or falling, until it reaches the appropriate position. This allows for the inspection of the housing 44, greatly improving the accuracy of the inspection. After inspection, the lifting transmission mechanism is reset, causing the bearing plate 4 and the housing 44 to move downwards to their initial positions, thus removing them from the top of the lifting seat 3 and completing the unloading process.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
