Description

Technical Field

[0001] This application relates to the field of assembly and testing equipment, and in particular to a gearbox assembly and testing device. Background Technology

[0002] In some existing gearboxes, the moving blocks and copper blocks are sequentially installed into the gearbox assembly slots during assembly to complete the assembly of the internal components. However, due to the significant amount of manual assembly work, human error can lead to incorrect or missing components, insufficient pressure during installation resulting in incomplete assembly, or inaccurate pressure causing tilting or damage, thus affecting the accuracy of gearbox assembly. Existing gearbox assembly inspection equipment can only detect the presence of copper blocks and moving blocks, but cannot assess the specific assembly details, resulting in low accuracy. The inventor believes that existing technology has room for improvement in terms of assembly accuracy and damage prevention. Summary of the Invention

[0003] In order to detect whether the copper bushing and moving block inside the gearbox are accurately assembled, this application provides a gearbox assembly detection device.

[0004] This application provides a gearbox assembly inspection device, which adopts the following technical solution: A gearbox assembly inspection device includes a first inspection frame, a second inspection frame, and a sorting component. The first inspection frame, the second inspection frame, and the sorting component are all mounted on a worktable of a frame. The first inspection frame is equipped with the first inspection component, which includes a first inspection probe, a laser detection array, and a first displacement sensor. The second inspection frame is equipped with the second inspection component, which includes a second inspection probe and a second displacement sensor. The frame is equipped with a rotating device, which includes a turntable and a rotation adjustment component. The turntable is equipped with multiple inspection stations. During the inspection operation, the inspection stations are respectively aligned with the first inspection frame, the second inspection frame, the sorting component, and the loading station.

[0005] By adopting the above technical solution, a turntable is set on the worktable of the frame to drive multiple sets of inspection stations to move sequentially under the first inspection component to check whether the copper sleeve is in place and whether there is any damage, cracks or missing pieces on the surface of the copper sleeve; then it moves under the second inspection component to check whether the movable block is in place; after that, the sorting component outputs the qualified gearboxes and rejects the unqualified gearboxes.

[0006] Optionally, the first detection frame includes a bracket, a slide rail on the bracket, a pressing cylinder on the bracket, the output rod of the pressing cylinder being fixedly connected to a slider, and the slider being slidably connected to the slide rail.

[0007] By adopting the above technical solution, the bottom structure of the first inspection frame is connected to the worktable of the frame, and the support is established through the bracket to support the lifting and moving movement of the sliding block connected to the pressing cylinder. The pressing cylinder controls the sliding block to move on the slide rail to change the vertical distance between the first inspection component and the inspection station, thereby realizing the inspection and processing of the assembly status of the copper block and other data.

[0008] Optionally, the slider is provided with a mounting base, the bottom of the mounting base is provided with an alignment optical axis, a limiting block is provided below the mounting base, the alignment optical axis passes through the limiting block and extends to the bottom of the limiting block, the bottom of the limiting block is provided with an abutment block, and the first detection component is provided on the mounting base.

[0009] By adopting the above technical solution, the slider establishes a connection with the first detection component through the mounting base, and the bottom of the mounting base is provided with an alignment optical axis to achieve guide alignment with the detection station, ensuring that the first detection component can be aligned with the gearbox on the detection station. When the alignment optical axis is inserted into the detection station, the bottom of the abutment block abuts against the gearbox through the abutment block to limit the gearbox and prevent it from moving and affecting the detection accuracy.

[0010] Optionally, the first detection component further includes a mounting plate disposed on the mounting base, the first displacement sensor disposed on the mounting plate, a sleeve disposed below the first displacement sensor, and the first detection probe disposed inside the sleeve and abutting against the first displacement sensor.

[0011] By adopting the above technical solution, the first detection component is fixedly mounted on the mounting base by the mounting plate. The sliding block is moved by the pressing cylinder to achieve a large-scale lifting control of the first detection component, so that the first detection component can quickly establish proximity with the gearbox. Then, the first detection probe moves in the opposite direction to drive the first displacement sensor to generate detection data, thereby determining whether the copper block is assembled in place.

[0012] Optionally, the lower end of the sleeve is provided with a detection groove, and the laser detection array includes multiple sets of side-mounted laser sensors and a set of bottom-mounted laser sensors, wherein the side-mounted laser sensors are located in the detection groove, and the bottom-mounted laser sensors are located at the bottom of the sleeve.

[0013] By adopting the above technical solution, a detection groove is set at the bottom of the sleeve in a position that does not interfere with the first detection probe for installing a side-mounted laser sensor. The three sets of side-mounted laser sensors can emit laser beams sufficient to cover the entire inner cavity of the gearbox to detect whether there are scratches or other damages on the inner wall of the gearbox. The bottom-mounted laser sensor is set at the bottom of the sleeve, which will not affect the floating of the first detection probe, and can emit laser beams to the copper sleeve and its surroundings. It can detect whether there are scratches, damage or missing pieces on the end face of the copper sleeve facing the first detection probe, and can check the distance between the copper sleeve and the mounting step to judge the assembly quality.

[0014] Optionally, the inner cavity of the first detection probe is provided with an iron core, and a conductive coil is wound on the iron core, with the bottom of the iron core abutting against the inside of the first detection probe.

[0015] By adopting the above technical solution, the iron core is set to abut against the first detection probe. After the iron core is wound with a coil and conducts electricity, it will generate magnetic force and concentrate the magnetic force at the contact end of the first detection probe with the iron core. That is, the bottom of the first probe has a certain magnetic force, which can pick up metal debris on the copper sleeve while detecting whether the copper sleeve is in place. When the coil is de-energized and the magnetic force disappears, the iron debris attached to the bottom of the first detection probe can be placed into the chip collection box to avoid affecting the next round of assembly and inspection.

[0016] Optionally, the sorting assembly includes multiple support frames, each support frame having a movable trough, the movable trough having a rotating screw, one end of the rotating screw being connected to a sorting motor, the movable trough having a movable block, one end of the movable block being connected to the rotating screw, the movable block having a transport cylinder on the side away from the movable trough, and the transport cylinder having a clamping element at its bottom.

[0017] By adopting the above technical solution, the sorting component is supported on the frame. The sorting component is equipped with a moving trough and a rotating screw to establish a connection with the moving block. The sorting motor drives the rotating screw to rotate, which drives the moving block to move on the moving trough. This can change the specific position of the moving block and drive the handling cylinder to control the clamping parts to move up and down to clamp the gearbox and place it at the defective product collection end and the qualified material placement end.

[0018] Optionally, the clamping element is a pneumatic gripper, and the two sets of gripping fingers of the pneumatic gripper are provided with anti-slip rubber pads on their opposite panels.

[0019] By adopting the above technical solution, the pneumatic gripper, in conjunction with the working command, picks up the gearbox that has completed the inspection and moves it to the corresponding position along with the moving block. The pneumatic gripper contacts the gearbox through the anti-slip rubber pad, which can enhance the anti-slip effect of gripping the fingers.

[0020] Optionally, the testing station includes a connecting seat, on which two sets of mounting brackets are provided. Each of the opposite panels of the mounting brackets is provided with a set of sliding connecting brackets. Each of the tops of the mounting brackets is provided with a set of alignment contact pieces, and each of the alignment contact pieces is provided with a set of alignment bearings.

[0021] By adopting the above technical solution, the testing station is connected to the workbench through the connecting seat, and the two sets of mounting brackets are connected to the gearbox through two sets of sliding connecting brackets. With the abutting action of the abutting block, the limiting effect on the gearbox can be guaranteed during the testing period, and the connection stability of the testing station to the gearbox can also be guaranteed during the transfer.

[0022] Optionally, the turntable is disposed on the worktable of the frame, the bottom of the turntable is fixedly connected to the rotation adjustment component, and the turntable is provided with multiple sets of chip collection boxes, which are respectively disposed between two adjacent sets of inspection stations.

[0023] By adopting the above technical solution, the turntable is rotatably connected to the worktable, and the rotating adjustment component drives the turntable to rotate on the worktable, thereby moving the inspection station to the bottom of the two sets of inspection frames and sorting components one by one. A chip collection box is set up to store the metal chips attracted by the electromagnet, so as to improve the assembly quality of the gearbox.

[0024] In summary, this application includes at least one of the following beneficial technical effects: A gearbox assembly inspection device includes a first inspection component on a first inspection frame for detecting the presence and proper installation of the copper bushing, as well as for checking for damage to the end face that could affect the gearbox assembly quality; and a second inspection component on a second inspection frame for detecting the presence and proper installation of the movable block, to determine whether the gearbox assembly meets the requirements. The entire inspection process of this device is completed by the inspection components without manual intervention, resulting in high inspection efficiency and the ability to quickly complete the inspection of gearbox assembly. Both the first and second testing frames of this application use cylinders to control the lifting and lowering of the testing components. During the electronic control process, two sets of probes are adjusted to detect the specific condition of the copper sleeve and the moving block. In addition, the laser sensor array set in the first testing component performs laser detection on the gear cavity and the surface of the copper sleeve. This can determine whether there are cracks, scratches, damage and missing pieces in the gearbox and the copper sleeve. The second testing component can also determine whether there is a moving block installed under the copper sleeve, and quickly identify and screen out gearboxes that do not meet the assembly standards. This application incorporates an electromagnet structure within the first detection probe, which generates a strong magnetic force at the bottom of the probe. This allows the electromagnet to pick up metal debris from the surface of the copper sleeve or the moving block without affecting the fit of the copper sleeve, thus preventing such metal debris from affecting the normal operation of the gearbox and eliminating potential safety hazards.

[0027] The following is in conjunction with the appendix Figure 1-9This application will be described in further detail.

[0028] This application discloses a gearbox assembly inspection device, referring to... Figures 1 to 3 The system includes a first testing frame 2, which includes a support 21. A slide rail 23 is mounted on the support 21. A pressing cylinder 22 is mounted on the support 21. The output rod of the pressing cylinder 22 is fixedly connected to a slider 24. The slider 24 is slidably connected to the slide rail 23. The pressing cylinder 22 extends and retracts, causing the slider 24 to slide on the slide rail 23. A mounting base 241 is mounted on the slider 24. An alignment optical axis 243 is located below the mounting base 241. A limiting block 242 is located at the bottom of the mounting base 241, and the alignment optical axis 243 passes through the limiting block. 242 extends into the lower part of the limiting block 242. The bottom of the limiting block 242 is provided with an abutment block 245. The bottom of the mounting base 241 is connected to the limiting block 242 by setting two sets of elastic buffer frames 244. When the first detection frame 2 is aligned with the gearbox 101 for detection, the alignment optical shaft 243 is inserted into the alignment bearing 115 of the detection station 11 to ensure the limiting control of the gearbox 101 by the first detection frame 2, so that the first detection probe 37 of the first detection component 3 can accurately extend into the gearbox 101 to complete the detection.

[0029] The first detection component 3, by mounting the mounting plate 31 on the mounting base 241, ensures the supporting function of the mounting base 241 for the first detection component 3. That is, the first detection component 3 moves up and down with the mounting base 241, which facilitates the first detection component 3 to quickly establish the detection alignment relationship with the gearbox 101. The first detection component 3 includes a first detection probe 37, a laser detection array, and a first displacement sensor 32. The first displacement sensor 32 is mounted on the mounting plate 31, and a sleeve 33 is provided below the first displacement sensor 32. The first detection probe 37 is located inside the sleeve 33 and is connected to the first detection probe 37. When the displacement sensor 32 comes into contact, that is, when the pressing cylinder 22 drives the first detection component 3 to move downward continuously, the first detection probe 37 will contact the copper sleeve 103. The reaction force of the pressing will push the first detection probe 37 upward, thereby generating a movement signal and being detected by the first displacement sensor 32. If the copper sleeve 103 is not installed in the gearbox 101, then within the specified movement range, no reaction force will be generated during the continuous pressing of the first detection probe 37, and the first displacement sensor 32 will not detect any data. Therefore, the detection signal fed back by the gearbox control terminal will not change, and the detection will fail.

[0030] The lower end of the sleeve 33 is provided with a detection groove 34. The laser detection array includes multiple sets of side-mounted laser sensors 35 and one set of bottom-mounted laser sensors 36. The side-mounted laser sensors 35 are located in the detection groove 34, and the bottom-mounted laser sensors 36 are located at the bottom of the sleeve 33. (Refer to...) Figure 3A data analysis terminal is provided between the slider 24 and the mounting plate 31. The detection slot 34 is set as an insulating protective layer to ensure that the several sets of side-mounted laser sensors 35 are not subject to electromagnetic interference in the detection slot 34 and can stably transmit and receive laser signals. During the downward movement of the first detection component 3, the side-mounted laser sensor 35 continuously emits laser signals to the inner cavity of the gearbox 101. The inner cavity of the gearbox 101 reflects the laser signals back to the side-mounted laser sensor 35. The data analysis terminal judges whether the inner wall of the gearbox 101 has defects such as scratches, cracks, or damage based on the laser reflection signal. At the same time, the bottom-mounted laser sensor 36 emits a laser towards the near end face of the copper sleeve 103. Similar to the detection process described above, the bottom-mounted laser sensor 36 can detect whether the near end face of the copper sleeve 103 has defects such as scratches, cracks, or damage. It can also detect the height difference between the edge of the copper sleeve 103 and the mounting step 102 of the assembly cavity of the gearbox 101, in order to determine the assembly accuracy and whether the assembly of the gearbox 101 needs to be reworked.

[0031] Reference Figure 4 The inner cavity of the first detection probe 37 is provided with an iron core, on which a conductive coil is wound. The bottom of the iron core abuts against the inside of the first detection probe 37, energizing the coil and generating a strong magnetic force at the bottom of the first detection probe 37. Without affecting the assemblability of the copper sleeve 103, this magnetic force can attract metal debris from the surface of the copper sleeve 103 or from the movable block 105 aligned with the through hole 104, so as to prevent these metal debris from affecting the normal use of the gearbox and eliminate safety hazards.

[0032] The bottom of the sleeve 33 is also equipped with a proximity sensor 38, which can detect the distance between the sleeve 33 and the copper sleeve 103, assisting the pressing cylinder 22 in judging the pressing distance, and avoiding the first detection probe 37 from being over-pressurized or not pressing in place.

[0033] The second detection frame 4 is equipped with a second detection component, which includes a second detection probe and a second displacement sensor. The structure of the second detection frame 4 is the same as that of the first detection frame 2. The difference between the two detection components is that the width of the second detection probe on the second detection component is smaller than the width of the first detection probe 37, which makes it easier for the second detection probe to extend into the through hole 104 in the center of the copper sleeve 103 to detect whether a movable block 105 is installed below the copper sleeve 103.

[0034] Secondly, the bottom of the sleeve of the second detection component is not equipped with a laser component, and it is only used to detect the assembly status of the movable block 105.

[0035] Reference Figure 5 and Figure 6The sorting component 5 includes multiple sets of support frames 51, which support the installation of the movable trough 52. The movable trough 52 is positioned above the defective product collection end 6 and the qualified product placement end 7, making it easier to place the gearbox 101 at the designated location. The movable trough 52 is equipped with a rotating screw, one end of which is connected to the sorting motor. The movable trough 52 is equipped with a moving block 53, one end of which is provided with an internal threaded hole and threadedly connected to the rotating screw. The sorting motor rotates synchronously with the rotating screw. The moving block 53 with the edge moves back and forth along the rotating screw and the movable trough 52, which facilitates the continuous movement of the gearbox 101 that has completed the inspection to the corresponding position. A conveying cylinder 54 is provided on the side of the moving block 53 away from the moving trough 52. A clamping member 55 is provided at the bottom of the conveying cylinder 54. In this embodiment, the clamping member 55 is a pneumatic gripper. The conveying cylinder 54 extends and retracts to drive the pneumatic gripper to move up and down, so as to facilitate the pneumatic gripper to grab the gearbox 101 and move and put down the gearbox 101 to achieve material sorting. Anti-slip rubber pads 552 are provided on the opposite panels of the two sets of clamping fingers 551 of the pneumatic gripper. The pneumatic gripper contacts the gearbox 101 through the anti-slip rubber pads 552, which can enhance the anti-slip effect of the clamping fingers 551 and ensure the safe transfer of the gearbox 101.

[0036] In other embodiments, the clamping member 55 may be used for transfer and clamping, such as a robotic arm or a locking device, and is not limited to the pneumatic gripper in this embodiment.

[0037] The detection device also includes a label detection camera 56 and a clamping detection camera 57 located between the second detection frame 4 and the sorting component 5. The label detection camera 56 is set directly opposite the detection station 11 on the sorting component via a connecting rod. It is used to photograph the label on the gearbox 101 at the detection station 11 and send the image to the control terminal to assist in judging whether the label is incorrect. If the label is correct, the gearbox 101 is transferred to the qualified material placement end 7. If the label is incorrect but the detection results of the copper sleeve 103 and / or the movable block 105 are correct, the gearbox 101 is transferred to the repairable defective product drop trough 62 of the defective product collection end 6. If the detection results of the copper sleeve 103 and / or the movable block 105 do not meet the detection standards, the gearbox 101 falls into the absolute defective product drop trough 61. The defective product collection end 6 is provided with defective product detection gratings 63 on the edges of the absolute defective product drop trough 61 and the repairable defective product drop trough 62 to count the number of defective products. The clamping detection camera 57 is used to clamp the gearbox 101 located next to the sorting component 5, and the pneumatic gripper is used to stably clamp the gearbox 101.

[0038] If the first detection probe 37 does not detect the copper sleeve 103, then the second detection component and the tag detection camera 56 do not need to be detected; if the first detection probe 37 detects the copper sleeve 103 but the second detection component does not detect the moving block 105, then the tag detection camera 56 does not need to be detected.

[0039] The first inspection frame 2, the second inspection frame 4, and the sorting component 5 are all located on the worktable of the frame 1. The frame 1 is equipped with a rotating device, which includes a turntable. The turntable is located on the worktable of the frame 1, and the bottom of the turntable is fixedly connected to the rotating adjustment component. The turntable is equipped with multiple inspection stations 11. During the inspection operation, a loading station is located on one side of the frame 1. Workers or automatic loading robots pick up gearboxes 101 and place them on the inspection stations in sequence. The rotating adjustment component drives the turntable to rotate, causing the inspection stations 11 to be aligned with the first inspection frame 2, the second inspection frame 4, the sorting component 5, and the loading station in turn. This ensures that the first inspection frame 2, the second inspection frame 4, and the sorting component 5 can be accurately aligned with the corresponding inspection stations 11 to complete the inspection or sorting, thereby ensuring the continuity and accuracy of the inspection operation.

[0040] In this embodiment, the rotation adjustment component is a DC motor. The output end of the DC motor is fixedly connected to the connection end at the center of the bottom of the turntable, in conjunction with the space inside the frame 1. The speed and amplitude of the turntable are controlled by the DC motor, so as to complete the smooth rotation in conjunction with the detection operation.

[0041] Reference Figure 7 The testing station 11 includes a connecting seat, on which two sets of mounting brackets 111 are provided. Each mounting bracket 111 has a set of sliding connecting brackets 112 on its opposite panel. Each mounting bracket 111 has a set of alignment contact pieces 114 on its top, and each alignment contact piece 114 has a set of alignment bearings 115. The testing station is stably connected to the turntable via the connecting seat. The two mounting brackets 111 are slidably connected to the gearbox 101 via the opposing sliding connecting brackets 112. It can be configured as a magnetic structure, which can enhance the firmness of the connection with the gearbox 101 and ensure the firmness of the connection between the gearbox 101 and the inspection station 11 when it is not in contact with the abutment block 245; an alignment contact piece 114 is provided to prevent the limit block 242 from impacting the inspection station 11, and a connection with the alignment optical shaft 243 is established through the alignment bearing 115. When the abutment block 245 is in tight contact with the gearbox 101, the alignment optical shaft 243 is inserted into the alignment bearing 115 to ensure the accuracy of the inspection operation.

[0042] A set of mounting brackets 111 is provided with abutment buckles 113, and abutment buckles 113 are provided with connection ports, which can be aligned and connected with the gear shaft of gearbox 101 to enhance the stability of gearbox 101.

[0043] Reference Figure 9The frame 1 is equipped with a protective shell around the first inspection frame 2, the second inspection frame 4 and the sorting component 5 to prevent material splashing and safety accidents, and to prevent external interference with the normal operation of the inspection. The protective shell is equipped with two sets of safety light curtains 14 at the feeding end to detect whether there are people in the work area and improve work safety. The frame 1 is equipped with a defective product cabinet door 15 at the outer end of the defective product collection end 6 to facilitate the removal and processing of defective products from the defective product cabinet door 15.

[0044] The turntable is equipped with multiple chip collection boxes 17, which are respectively located between adjacent detection stations 11. The chip collection boxes 17 are located on the axis of the first detection probe 37. After the detection station 11 moves away from below the first detection probe 37, the chip collection box 17 will rotate to the first detection probe 37 and collect the metal chips that fall off when the power is off.

[0045] The rack 1 is also equipped with an emergency stop button 12 and a fingerprint start button 13, which gives the inspection operation dedicated work authority and safety emergency stop device to ensure the safety of the inspection operation.

[0046] Reference Figure 8 A top-pressure cylinder 16 is provided below the turntable corresponding to the first inspection frame 2 and the second inspection frame 4. When the inspection station 11 is in working condition, the top-pressure cylinder 16 pushes upward to enhance the docking degree between the gearbox 101 on the inspection station 11 and the inspection component.

[0047] Reference Figures 1 to 9 This application embodiment discloses a gearbox assembly inspection device. A worker or robot places a gearbox 101 on the inspection station 11 at the loading station. When the gearbox 101 rotates to the first inspection frame 2 with the turntable, the turntable stops rotating, and the pressing cylinder 22 pushes the first inspection component 3 down to press the first inspection probe 37 into the gearbox 101 to check whether the copper sleeve 103 is in place. During this process, the laser inspection array set on the sleeve 33 inspects the condition of the inner wall of the gearbox 101, the condition of the copper sleeve 103 near the end face, and the distance between the copper sleeve 103 and the mounting step 102. After the inspection is completed and confirmed to be correct, the gearbox 101 moves with the turntable to the bottom of the second inspection component, and the second inspection probe checks whether there is a movable block 105 below the copper sleeve 103. After the inspection is completed and confirmed to be correct, the gearbox 101 moves with the turntable to the sorting component 5. The label inspection camera 56 judges the label result, and then the clamping member 55 grabs the gearbox 101 to the corresponding position for sorting.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
