Description

Technical Field

[0001] This application relates to the technical field of shaft inspection equipment, and in particular to an automatic full inspection machine for the outer diameter of shafts. Background Technology

[0002] With the development of technology, electric toothbrushes have gradually entered people's daily lives. Electric toothbrushes are toothbrushes that use a built-in vibrating motor to make the brush head oscillate at a high frequency, making it easier for users to clean their teeth.

[0003] Vibratory motors typically require a shaft to connect to the brush head. The two ends of this shaft usually have different shapes. One type of shaft, as shown in the figure, is thicker in the middle and thinner at both ends compared to the middle. However, one side of the shaft has a segmental change while the other side remains constant, and both ends are of the same thickness. During assembly in the factory, the shaft's orientation must be ensured. However, due to the large number of shafts that need to be processed in actual production, prolonged sorting and orientation adjustments by workers can easily lead to errors, affecting subsequent production and causing considerable inconvenience. Utility Model Content

[0004] To facilitate shaft orientation sorting and reduce the occurrence of incorrect orientation, this application provides an automatic full inspection machine for the outer diameter of shafts.

[0005] This application provides an automatic full inspection machine for the outer diameter of shafts, which adopts the following technical solution:

[0006] An automatic full inspection machine for the outer diameter of a shaft includes a frame, a stuffing box, a transfer mechanism, a primary positioning seat, a rotating seat, a repositioning seat, a feeding mechanism, and a receiving box. The stuffing box and the receiving box are fixedly mounted on the frame. The primary positioning seat, the rotating seat, and the repositioning seat are mounted side by side on the frame. The transfer mechanism is used to move the shaft sequentially on the stuffing box, the primary positioning seat, the rotating seat, and the repositioning seat. The frame is provided with a first detection mechanism for detecting the shaft direction on the primary positioning seat. The frame is also provided with a second detection mechanism for detecting the shaft direction on the repositioning seat. The feeding mechanism is used to move the shaft sequentially in the repositioning seat, the second detection mechanism, and the receiving box.

[0007] By adopting the above technical solution, during use, two shafts with different orientations are filled into the stuffing box. The stuffing box unloads the shafts, and the transfer mechanism transfers the shafts released from the stuffing box to the initial positioning seat. The initial positioning seat positions the shafts, and the first detection mechanism detects the orientation of the shafts. After detection, the transfer mechanism moves the shafts from the initial positioning seat to the rotating seat. The rotating seat determines whether to rotate and adjust the orientation based on the detection result of the first detection mechanism. After adjustment, the transfer mechanism moves the shafts to the repositioning seat. Then, the positioned shafts are moved by the unloading mechanism to the second detection mechanism for re-detection. Shafts that pass the detection are moved by the unloading mechanism to the receiving box for storage, while shafts with abnormalities are moved outside the receiving box for classification. Through two-stage detection, the orientation of the shafts is effectively adjusted, and the situation of incorrect orientation of the adjusted shafts is effectively reduced.

[0008] Preferably, the rotating base includes a rotary cylinder fixedly mounted on the frame and a turntable fixedly connected to the output shaft of the rotary cylinder. The end of the turntable away from the rotary cylinder is formed with a receiving block for storing the shaft.

[0009] By adopting the above technical solution, and by setting up a rotary cylinder and a turntable, when the orientation of the rotating shaft needs to be changed, the rotary cylinder is started by venting air, and the output shaft of the rotary cylinder rotates, thereby driving the turntable to rotate. The rotation of the turntable will drive the receiving block to rotate, thereby driving the shaft placed in the receiving block to rotate.

[0010] Preferably, the initial positioning seat is equipped with a positioning wheel set for positioning the shaft, and two sets of the positioning wheel set are arranged opposite each other on the initial positioning seat.

[0011] By adopting the above technical solution and setting up positioning wheel sets, the two sets of positioning wheel sets facilitate the precise positioning of the shaft, making it easier for the first inspection mechanism to inspect the shaft.

[0012] Preferably, the first detection mechanism is a laser sensor fixedly installed on the packing box, and the laser sensor is positioned facing one side of the shaft located on the initial positioning seat.

[0013] By adopting the above technical solution, and through the setting of the laser sensor, the laser sensor can detect the width of the axis in which the laser sensor is facing. Since the axis is shaped like a thicker end and a thinner end, when the thicker axis is facing the laser sensor, the laser emitted by the laser sensor will be blocked and reflected earlier, while when the thinner axis is facing the laser sensor, the laser emitted by the laser sensor will be blocked and reflected later. During detection, a distance difference will be generated, thereby realizing the ability to distinguish the thickness of the axis through the laser sensor, and thus determine the orientation of the axis.

[0014] Preferably, the packing box includes a box body fixedly installed on the frame, a material picking plate slidably installed on the box body, and a material unloading plate fixedly installed on the frame. The material picking plate has a material picking groove. The box body is provided with a drive cylinder for driving the material picking plate to move. The width of the inside of the box body is the same as the length of the shaft. The material unloading plate is formed with a stop for limiting the shaft.

[0015] By adopting the above technical solution, workers place a large number of shafts in the box. The shafts in the box are stacked, and the shafts near the picking plate are embedded in the picking slots on the picking plate. As the picking plate moves, they move to the unloading plate, thus realizing the unloading of shafts one by one in the box. The falling shafts are blocked by the stop blocks, thereby limiting the falling position.

[0016] Preferably, the transfer mechanism includes a first mounting base fixedly connected to the frame, a vertical sliding plate slidably disposed on the first mounting base, a horizontal sliding plate slidably disposed on the vertical sliding plate, a first pneumatic gripper fixedly disposed on the horizontal sliding plate, three first pneumatic grippers evenly spaced on the horizontal sliding plate, a vertical cylinder for driving the vertical sliding plate to move fixedly disposed on the first mounting base, and a horizontal cylinder for driving the horizontal sliding plate to move fixedly disposed on the vertical sliding plate.

[0017] By adopting the above technical solution, the horizontal cylinder and the vertical cylinder realize the movement of the first pneumatic gripper in the horizontal and vertical directions, realizing the two-way movement of the first pneumatic gripper. The first pneumatic gripper is connected to the external air passage, and the shaft can be clamped by air supply. In use, the first pneumatic gripper moves down and starts when it moves to the corresponding position to clamp the shaft, then lifts and moves horizontally, moves to the next position and moves down again, and after moving down to the designated position, it contacts the clamp and releases the shaft, thereby realizing the movement of the shaft.

[0018] Preferably, the second detection mechanism includes a connecting block fixedly installed on the frame, a jet pipe fixedly installed on the connecting block, and an air collection pipe fixedly installed on the connecting block. The connecting block is provided with a limiting groove for limiting the shaft, and multiple sets of jet pipes and air collection pipes are arranged opposite to each other.

[0019] By adopting the above technical solution, when the shaft moves into the limiting groove, the gas ejected from the jet pipe will pass through the shaft. The thicker part of the shaft blocks more gas, and the gas collecting pipe receives less gas. The thinner part of the shaft blocks less gas, and the gas collecting pipe receives more gas. The thickness of the shaft causes a significant difference in the amount of gas received by the gas collecting pipe. Therefore, by observing the amount of gas received by the gas collecting pipe, it is possible to clearly determine which side is the thicker part of the shaft and which side is the thinner part, thus determining whether the direction of the shaft is correct.

[0020] Preferably, the unloading mechanism includes a second mounting base fixedly mounted on the frame, a spatial movement component mounted on the second mounting base, and a second pneumatic gripper mounted on the spatial movement component.

[0021] By adopting the above technical solution, the spatial moving component will use the second pneumatic gripper to pick up the shaft placed on the repositioning seat, and then move it to the second detection mechanism for re-inspection. After the inspection is completed, the spatial moving component will determine whether to move the shaft into the receiving box based on the inspection results.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up the initial positioning seat, the rotating seat, and the laser sensor, the shaft moves to the initial positioning seat for positioning. Then, the laser sensor detects the shaft. After detection, the shaft is rotated by the rotating seat, thereby adjusting the shaft to the same direction and thus adjusting the shaft towards sorting.

[0024] 2. With the setting of the repositioning seat and the air jet detection mechanism, the shaft after being adjusted will be placed in the repositioning seat and moved from the repositioning seat to the air jet detection mechanism. The air jet detection mechanism performs air jet detection to distinguish the thickness of the two sides of the shaft, thereby ensuring that the shafts are oriented in the same direction when they are fed and reducing the occurrence of incorrect orientation.

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail.

[0033] This application discloses an automatic full inspection machine for the outer diameter of shafts.

[0034] like Figure 1 and 2As shown, an automatic full inspection machine for the outer diameter of shafts includes a frame 1, a stuffing box 2, a transfer mechanism 3, a primary positioning seat 4, a rotating seat 5, a repositioning seat 6, a feeding mechanism 7, and a receiving box 8. The stuffing box 2 includes a box body 21 welded to the frame 1, a feeding plate 22 slidably connected to the box body 21, and a feeding plate 23 welded and fixed to the frame 1. The internal width of the box body 21 is the same as the length of the shaft. Multiple shafts can be placed and stacked horizontally inside the box body 21. The box body 21 has an opening on the upper side to facilitate the user to place the shaft inside the box body 21 from above. The bottom of the box body 21 is inclined. The shafts placed inside the box 21 are stacked at the lowest point inside the box 21 due to gravity. An opening, allowing only one shaft to pass through, is located below the side panel of the box 21 at this point. This opening corresponds to and is parallel to the lowest point of the bottom of the box 21. A material-retrieving plate 22 is slidably connected to the outside of the side panel of the box 21 at this point and is driven up and down by a cylinder mounted on the box 21. The material-retrieving plate 22 has a material-retrieving slot 40 that can only accommodate one shaft, and the lower half of the slot 40 is open for easy unloading. The box 21 is equipped with useful... The drive cylinder 50 moves the material picking plate 22, allowing the material picking groove 40 on the material picking plate 22 to align with the opening on the side plate of the box body 21. It also moves the material picking groove 40 on the material picking plate 22 to the lower side of the box body 21. The material feeding plate 23 is located below the material picking plate 22 and is inclined. An integrally formed stop 60 for limiting the shaft is on the material feeding plate 23. The internal width of the stop 60 is slightly larger than the length of the shaft, allowing the shaft to slide smoothly down the material feeding plate 23. In use, workers stack a large number of shafts inside the box body 21. The stacked shafts will enter the opening below the side plate of the box 21 in sequence, and only one shaft can enter at a time. When the shaft entering the opening moves to the opening through the picking groove 40 on the feeding plate 23, it will be affected by the pressure of the shaft above and will move into the picking groove 40. As the feeding plate 22 continues to move, when the picking groove 40 moves out of the box 21, without the obstruction of the box 21, the shaft will fall onto the feeding plate 23 along the open picking groove 40 and be blocked and limited by the stop block 60. The shaft will move along the feeding plate 23 to the lowest point of the feeding plate 23, thus completing the sequential feeding of a single shaft.

[0035] like Figure 1 , Figure 3 and Figure 4As shown, the initial positioning seat 4 is fixedly installed on the frame 1 by bolts. A positioning wheel set 30 for positioning the shaft is rotatably connected above the initial positioning seat 4. Each positioning wheel set 30 contains two positioning wheels, which are spaced apart. The gap between the two positioning wheels is less than the width of the shaft end. In this embodiment, two sets of positioning wheel sets 30 are arranged opposite each other on the initial positioning seat 4. In use, the shaft can be placed on the two opposite positioning wheel sets 30, so that the end of the shaft is located in the gap between the two positioning wheels. Since the gap between the two positioning wheels is less than the width of the shaft, the positioning wheel set 30 can be positioned and the shaft can be centered, so that the shaft can be placed in a horizontal position.

[0036] like Figure 1 and 2 As shown, the frame 1 is provided with a first detection mechanism 9 for detecting the shaft direction located on the initial positioning seat 4. The first detection mechanism 9 is a laser sensor. The laser sensor is installed on the side of the stop 60 facing the initial positioning seat 4 by bolts, and the probe of the laser sensor faces the shaft placed on the initial positioning seat 4. The detection probe of the laser sensor faces the non-middle position of the shaft placed on the initial positioning seat 4, for detecting the part with different radii at both ends of the shaft.

[0037] like Figure 3 and 4 As shown, the rotating seat 5 is mounted on the frame 1, and is located at the end of the initial positioning seat 4 away from the unloading plate 23. The rotating seat 5 includes a rotary cylinder 51 bolted to the frame 1 and a turntable 52 bolted to the output shaft of the rotary cylinder 51. The end of the turntable 52 away from the rotary cylinder 51 has an integrally formed receiving block 20 for receiving the shaft. The receiving block 20 has a groove for receiving the shaft, which can be placed and positioned in the groove. In use, the rotary cylinder 51 is connected to an external air pipe, and when the rotary cylinder 51 is ventilated, its output shaft rotates, driving the turntable 52 to rotate 180°.

[0038] like Figure 3 and 4 As shown, the repositioning seat 6 is fixedly mounted on the frame 1 by bolts, and the repositioning seat 6 is located on the side of the rotating seat 5 away from the initial positioning seat 4. In this embodiment, the initial positioning seat 4, the rotating seat 5, and the repositioning seat 6 are aligned and located on the same straight line. The shaft can move sequentially along the straight line between the initial positioning seat 4, the rotating seat 5, and the repositioning seat 6. The repositioning seat 6 also has an integrally formed groove for accommodating the shaft, and the shaft can be placed and positioned in the groove on the repositioning seat 6.

[0039] like Figure 1 and 3As shown, the transfer mechanism 3 includes a first mounting base 31 bolted to the frame 1, a vertical sliding plate 32 slidably mounted on the first mounting base 31, and a horizontal sliding plate 33 slidably mounted on the vertical sliding plate 32. A vertical cylinder 70 for driving the vertical sliding plate 32 to move vertically is bolted to the first mounting base 31. The piston rod of the vertical cylinder 70 is welded and fixed to the vertical sliding plate 32. A guide rod is also mounted on the first mounting base 31, passing through the vertical sliding plate 32. The guide rod moves in the same direction as the piston rod of the vertical cylinder 70, thus stabilizing the movement. A horizontal cylinder 80 for driving the horizontal sliding plate 33 to move is bolted to the vertical sliding plate 32. The piston rod of the horizontal cylinder 80 is welded and fixed to the vertical sliding plate 32. The first pneumatic gripper 34 is fixed on the horizontal sliding plate 33 and is bolted to the horizontal sliding plate 33. Three first pneumatic grippers 34 are evenly spaced on the horizontal sliding plate 33, and the three first pneumatic grippers 34 correspond to the positions of the shaft on the initial positioning seat 4, the rotating seat 5, and the repositioning seat 6. In this embodiment, the distance between the shaft located at the unloading plate 23 and the shaft located at the initial positioning seat 4 is also equal to the interval between the gripping positions of two adjacent first pneumatic grippers 34. This allows the three first pneumatic grippers 34 to simultaneously grip the shaft at the unloading plate 23, the initial positioning seat 4, and the rotating seat 5, or simultaneously grip the shaft at the initial positioning seat 4, the rotating seat 5, and the repositioning seat 6 when the horizontal sliding plate 33 moves.

[0040] like Figure 1 and 3As shown, during use, the vertical cylinder 70, horizontal cylinder 80, and first pneumatic gripper 34 are connected to the external air passage. The shaft, after being picked up by the material-picking plate 22, falls individually to the unloading plate 23. The vertical cylinder 70 is activated, pushing the vertical sliding plate 32 to move, thus causing the first pneumatic gripper 34 to fall. After the piston rod of the vertical cylinder 70 moves to its maximum position, the first pneumatic gripper 34 activates, gripping the shaft located on the unloading plate 23. Then, the piston rod of the vertical cylinder 70 retracts, lifting the gripped shaft. The horizontal cylinder 80 is activated, pushing the horizontal sliding plate 33 to move, thus causing the first pneumatic gripper 34 to move horizontally. After the horizontal cylinder 80 moves to its maximum position, the vertical cylinder 70 is activated again, causing the first pneumatic gripper 34 to fall again. After falling, the first pneumatic gripper 34 opens, releasing the gripped shaft into the initial positioning seat 4, thereby moving the shaft originally located on the unloading plate 23 to the initial positioning seat. At point 4, since three first pneumatic grippers 34 are equally spaced, using the above process, the three first pneumatic grippers 34 work simultaneously, which can simultaneously complete the movement of the shaft from the unloading plate 23 to the initial positioning seat 4, the movement of the shaft from the initial positioning seat 4 to the rotating seat 5, and the movement of the shaft from the rotating seat 5 to the repositioning seat 6. When the shaft is located on the initial positioning seat 4, the laser sensor will detect the shaft located on the initial positioning seat 4. Due to the different thicknesses on both sides of the shaft, the detection results of the laser sensor are different. The detection results will be fed back to the external PLC equipment. The PLC equipment receives and processes the signal, and then sends a signal to control whether the rotating seat 5 rotates after the next shaft movement. After the shaft located on the initial positioning seat 4 moves to the rotating seat 5, the rotating seat 5 determines whether to rotate according to the signal sent by the PLC equipment, thereby adjusting the orientation of the shaft. After the orientation of the shaft is adjusted, the shaft will be moved to the repositioning seat 6 for placement.

[0041] like Figure 3 and 5As shown, the frame 1 is also equipped with a second detection mechanism 10 for detecting the axial direction on the positioning seat. The second detection mechanism 10 includes a connecting block 101 fixed to the frame 1 by bolts, a jet pipe 102 snapped onto the connecting block 101, and a gas collecting pipe 103 snapped onto the connecting block 101. A limiting groove 90 for limiting the shaft is opened in the center of the connecting block 101. The width of the limiting groove 90 is the same as the widest position on the shaft, which can snap and limit the shaft in the limiting groove 90. The jet pipe 102 and the gas collecting pipe 103 are located on both sides of the limiting groove 90, and the jet pipe 102 and the gas collecting pipe 103 are arranged opposite each other. In this embodiment, four pairs of jet pipes 102 and gas collecting pipes 103 are arranged opposite each other at equal intervals. 2. Connected to external gas pipelines, the gas collection pipe 103 is connected to the flow detection device, and the gas pressure ejected from the four jet pipes 102 is constant. The four gas collection pipes 103 are independently connected to the flow detection device, which can read the flow rate of the four gas collection pipes 103 respectively. In use, the shaft is placed in the limiting groove 90. Due to the different thicknesses of the shaft, the shaft located in the limiting groove 90 will block the gas ejected from the four jet pipes 102 to varying degrees, thus affecting the flow rate in the four gas collection pipes 103. The flow rate data in the four gas collection pipes 103 is fed back to the external PLC device. The external PLC device reads the flow rate data and compares it, so that the thickness of the shaft at the corresponding position can be obtained according to the flow rate, thus obtaining the placement of the shaft.

[0042] like Figure 3As shown, a feeding mechanism 7 is provided on the frame 1. The feeding mechanism 7 includes a second mounting base 71 fixedly mounted on the frame 1 by bolts, a spatial movement component 72 mounted on the second mounting base 71, and a second pneumatic gripper 73 mounted on the spatial movement component 72. The spatial movement component 72 includes a transverse slide rail 721 and a vertical slide rail 722. A cylinder is fixedly mounted on the second mounting base 71 by bolts. The piston rod of the cylinder is welded and fixed to the transverse slide rail 721, and the transverse slide rail 721 is limited by the second mounting base 71, allowing it to only move along the internal groove structure of the second mounting base 71. The slide rail 721 is bolted to a first motor, and a first lead screw is mounted on the shaft of the first motor via a coupling. The first lead screw is threaded onto the vertical slide rail 722, and the vertical slide rail 722 is limited by the horizontal slide rail 721, so it can only slide along the internal groove structure of the horizontal slide rail 721. A second motor is mounted on the vertical slide rail 722, and a second lead screw is mounted on the shaft of the second motor via a coupling. A moving block is also slidably connected to the vertical slide rail 722, and the second lead screw is threaded onto the moving block. The moving block is bolted to the second pneumatic gripper 73. In use, the cylinder on the second mounting base 71 is connected to an external air pipeline. When the cylinder on the second mounting base 71 is activated, the movement of the piston rod of the cylinder on the second mounting base 71 controls the movement of the horizontal slide rail 721, thereby driving the vertical slide rail 722 to move. This causes the second pneumatic gripper 73 connected to the vertical slide rail 722 to move, thus controlling the second pneumatic gripper 73 to move above the repositioning seat 6 and the second detection mechanism 10. The first motor on the horizontal slide rail 721 is connected to an external power source. When the first motor is activated, its shaft rotates, and the first lead screw rotates. Due to the vertical slide rail 721... The screw 22 is threaded onto the first lead screw. When the vertical slide rail 722 is limited by the horizontal slide rail 721, the rotation of the first lead screw will cause the vertical slide rail 722 to move along the horizontal slide rail 721, thereby realizing the horizontal movement of the second pneumatic gripper 73. The second motor on the vertical slide rail 722 is connected to an external power source. When the second motor starts, the shaft of the second motor rotates, and the second lead screw rotates. Since the moving block is threaded onto the second lead screw and is limited by the vertical slide rail 722, the rotation of the second lead screw will cause the moving block to move along the vertical slide rail 722, thereby realizing the vertical movement of the second pneumatic gripper 73.

[0043] like Figure 1 and 3 As shown, a receiving box 8 is also bolted onto the frame 1. The internal width of the receiving box 8 is slightly larger than the length of the shaft. When the shaft is placed horizontally inside the receiving box 8, it will be limited by the inner wall and cannot rotate. The receiving box 8 is located in the horizontal direction of the second detection mechanism 10. The movement of the transverse slide rail 721 can realize the movement of the second pneumatic gripper 73 between the second detection mechanism 10 and the receiving box 8, so that the detected parts gripped by the second pneumatic gripper 73 are placed in the receiving box 8.

[0044] The implementation principle of this application embodiment is as follows: When put into actual use, the shaft placed in the filling box 2 will be sequentially unloaded by the moving material plate 22. After unloading, the shaft is clamped by the first pneumatic gripper 34 and moved to the laser sensor for detection. After determining the shaft direction, the shaft is moved to the rotating seat 5 and the shaft orientation is adjusted by rotation. After adjustment, it is moved to the repositioning seat 6. At this time, the first step of shaft detection and adjustment is completed. Then, the shaft will be clamped by the second pneumatic gripper 73 and moved to the second detection mechanism 10 for air jet detection, thereby determining the shaft orientation and ensuring that the shaft orientation is correct. After successful detection, the second pneumatic gripper 73 will clamp the shaft and place it in the receiving box 8 for storage, thereby completing the one-way storage of the shaft.

[0045] 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.
