Description

Technical Field

[0001] This utility model relates to the field of sensor manufacturing, and in particular to a sensor clamping device and a sensor marking system. Background Technology

[0002] In the manufacturing process of precision sensing components, using laser marking to permanently assign product identification information is a standard procedure to ensure traceability. With the development of modular and integrated sensors, the demand for high-precision marking on their outer shells or multiple orthogonal planes is increasingly prominent, the so-called "double-sided marking." Current technology generally employs a process of "marking one side, then manually disassembling, flipping, and reinstalling, before marking the other side." This method not only relies on manual operation, leading to low production efficiency and high labor costs, but also makes it difficult to ensure consistent positioning during the secondary clamping process. This results in errors in the relative positions of the two markings, seriously affecting product accuracy and quality, and has become a significant bottleneck restricting the improvement of automated production levels.

[0003] Therefore, there is an urgent need for a sensor clamping device and a sensor marking system that can achieve double-sided marking with a single clamping. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low processing efficiency and difficulty in ensuring positioning accuracy caused by the need for manual flipping and repeated clamping during the double-sided marking process of sensors.

[0005] To solve the above-mentioned technical problems, this utility model discloses a sensor clamping device. The sensor has a mounting plate and a sensor body. The sensor body has a front and a back. The sensor body is perpendicular to the mounting plate. The clamping device includes:

[0006] The support frame extends along its length;

[0007] The rack is connected to the support frame in a manner movable along the length direction, and has a first position and a second position;

[0008] A support frame extends along the height direction and is fixedly connected to the bearing frame; along the width direction, the support frame has a groove on the side near the bearing frame, and the bottom wall of the groove has a first through hole, which penetrates the support frame along the width direction;

[0009] A gear is disposed in the groove, meshes with the rack, and is rotatably connected to the groove; the gear has a mounting groove that is adapted to the shape of the mounting plate; the gear has a second through hole that penetrates the gear along the width direction, and the sensor body passes through the first through hole and the second through hole;

[0010] When the rack is in the first position, it can make the front face face the positive direction of the height direction;

[0011] When the rack is in the second position, it can make the reverse side face the positive direction of the height direction.

[0012] Using the above technical solution, the front and back sides of the sensor are arranged opposite each other. The sensor is clamped on a gear, and the sensor body passes through and extends out of the first and second through holes for marking. Initially, the rack is in the first position, with the front side of the sensor facing upwards and aligned with the marking device (e.g., a marking machine), completing front marking. Due to the meshing transmission between the gear and rack, the linear displacement of the rack is converted into the rotational motion of the gear. Subsequently, the rack is driven to move linearly to the second position. The rack movement drives the gear to rotate, which in turn drives the sensor to perform a 180° fixed-point rotation, so that the back side of the sensor body faces upwards and aligns with the marking machine, completing back marking. Finally, double-sided marking is completed in a single clamping operation, eliminating positioning errors caused by secondary clamping and improving processing accuracy and production efficiency.

[0013] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a sensor clamping device, wherein the support frame has a first end and a second end along the length direction; the rack is offset from the first end and the second end in the width direction;

[0014] The clamping device further includes:

[0015] A limiting block is provided at one end of the rack near the first end;

[0016] A first limiting bolt passes through the first end along the length direction and has a first limiting surface, which is located between the first end and the limiting block.

[0017] The second limiting bolt passes through the second end along the length direction and has a second limiting surface, which is located between the second end and the limiting block;

[0018] When the rack is in the first position, the limiting block abuts against the first limiting surface;

[0019] When the rack is in the second position, the limiting block abuts against the second limiting surface.

[0020] The above technical solution uses a first limiting bolt, a second limiting bolt, and corresponding limiting surfaces to limit the rack's movement to a first and second position, respectively. Specifically, when the rack reaches the first position, the limiting block abuts against the first limiting surface, preventing the rack from continuing to move in that direction, thus determining the rack's travel endpoint (i.e., the first position). When the rack reaches the second position, the limiting block abuts against the second limiting surface, preventing the rack from continuing to move in the opposite direction, similarly precisely limiting the rack's endpoint position (i.e., the second position). This achieves mechanical limiting of the rack's linear motion stroke, ensuring the accuracy and consistency of the gear's rotation angle each time, and enabling the sensor's front and back sides to be accurately positioned to the preset position. It effectively avoids marking position deviations caused by overshoot or positioning drift, further improving the reliability and product yield of the double-sided marking process.

[0021] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a sensor clamping device, which further includes:

[0022] A first buffer extends through the first end along the length direction and is spaced apart from the first limiting bolt. Along the length direction, the end of the first buffer near the second end extends beyond the first limiting surface.

[0023] The second buffer extends through the second end along the length direction and is spaced apart from the second limiting bolt. Along the length direction, the end of the second buffer closer to the first end extends beyond the second limiting surface.

[0024] By employing the above technical solution, a first buffer and a second buffer are added, both of which can elastically extend and retract along their length. When the rack moves to the first position, the limiting block first contacts and compresses the first buffer, absorbing most of the impact energy through the deformation of the first buffer, before contacting the first limiting surface. When the rack moves to the second position, the limiting block first contacts and compresses the second buffer, absorbing most of the impact energy through the deformation of the second buffer, before contacting the second limiting surface. This achieves buffered limiting in both the first and second positions. In other words, it provides buffering damping when the rack approaches the end of its stroke, effectively absorbing the rack's kinetic energy and mitigating the rigid impact between the limiting block and the first or second limiting bolt.

[0025] According to another specific embodiment of the present invention, a sensor clamping device is disclosed, wherein the end of the first buffer near the second end and the end of the second buffer near the first end are both provided with rubber.

[0026] By employing the above technical solution and incorporating rubber at the ends of the first and second buffers, the buffering performance is further optimized. The rubber material, with its high damping characteristics and elastic deformation capacity, effectively attenuates impact energy. This not only enhances the protection of the sensor and reduces the risk of sensor wear, but also further suppresses noise.

[0027] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a sensor clamping device, which further includes:

[0028] A support shaft extends along the length direction and is disposed on the support frame;

[0029] A slider is sleeved on the support shaft, the slider can move along the support shaft, and is fixedly connected to the rack.

[0030] By adopting the above technical solution, the rack is driven to move by driving the slider along the support axis, thereby providing stable and precise guidance for the linear motion of the rack.

[0031] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a sensor clamping device, which further includes:

[0032] Multiple positioning blocks, a portion of which is fixedly connected to the support frame, and another portion protruding from the groove, are spaced apart from the gear along the width direction.

[0033] By employing the above technical solution, multiple locating blocks spaced laterally from the gear provide stable and reliable axial positioning for the gear, i.e., positioning along the width direction; and compared to contact with the gear, friction is reduced. Specifically, the locating blocks effectively constrain the axial movement of the gear under high-speed rotation or stress, preventing the gear from separating from the rack and ensuring the stability of the gear-rack meshing transmission.

[0034] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a sensor clamping device, which further includes:

[0035] Base;

[0036] The support frame is connected to the base in a manner that allows it to move along the height direction.

[0037] By adopting the above technical solution, by adding a base and making it a moving pair in the height direction with the support frame, the overall height of the clamping device is made adjustable, which enables the sensor to flexibly adapt to the working distance of different marking equipment and improves the versatility of the device.

[0038] In addition, in conjunction with the following sensor marking system, the front or back of the sensor body must remain in contact with the worktable during operation to ensure stability. Furthermore, since the sensor body is a non-cylindrical structure, when it needs to be flipped, the sensor must be raised through a height adjustment mechanism to prevent the sensor body from colliding with the worktable due to structural interference during rotation.

[0039] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a sensor clamping device, wherein at least a portion of the mounting plate is made of magnetic material;

[0040] The gear is provided with a magnetic attraction part, which is located in the mounting groove and corresponds to the magnetic material of the mounting plate; the gear is fixedly connected to the mounting plate through the magnetic attraction part.

[0041] The above technical solution utilizes the adsorption between the magnetic suction part and the magnetic mounting plate to achieve rapid clamping and disassembly of the sensor. This not only simplifies operation and significantly improves material changing efficiency, but also avoids component wear or surface damage that may be caused by traditional mechanical clamping.

[0042] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a sensor clamping device, wherein the gear is provided with a connecting part, the connecting part is located on the side of the gear close to the groove along the width direction, and the second through hole penetrates the connecting part along the width direction;

[0043] The connecting part is located in the first through hole, and the gear and the support frame are rotatably connected through the connecting part.

[0044] By adopting the above technical solution, a connecting part is set on the gear, which serves as a through-hole channel for the sensor. This ensures that the sensor body remains in a non-contact state with the support frame during the flipping process, effectively avoiding surface scratches and structural damage caused by relative movement or direct contact with the support frame.

[0045] This utility model also discloses a marking system for sensors, comprising:

[0046] Such as the sensor clamping device in any of the above embodiments;

[0047] The sensor body can pass through and extend out of the first through hole;

[0048] A worktable is used to abut against the end of the sensor that extends out of the first through hole;

[0049] A marking machine, located directly above the workbench, is used to mark the sensor body. Attached Figure Description

[0080] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0081] refer to Figure 1A , Figure 1B This application provides a sensor 100, which has a mounting plate 110 and a sensor body 120, with the sensor body 120 perpendicular to the mounting plate 110. The mounting plate 110 is a plate-shaped structure that is narrower at one end and wider at the other. The mounting plate 110 has a bushing 111, which is annular and made of magnetic material. In some possible embodiments, the shape of the mounting plate 110 includes, but is not limited to, the above-described shapes, and can also be square, elliptical, circular, etc. The mounting plate 110 may not include the bushing 111, as long as the mounting plate 110 includes a portion made of magnetic material.

[0082] refer to Figure 1A , Figure 1B In this embodiment, the sensor body 120 has a front side 121 and a back side 122, which are arranged opposite to each other. It is now required to mark on the front side 121 and the back side 122 respectively. The clamping device of the existing marking system cannot complete double-sided marking under the condition of one clamping, and the sensor 100 needs to be manually flipped, which is inefficient.

[0083] refer to Figure 2 To address the above problems, this application provides a sensor marking system 300, comprising: a sensor clamping device 200, a worktable 310, and a marking machine 320. (Reference) Figure 2 , Figure 3 A sensor clamping device 200 includes: a carrier frame 210, a rack 220, a support frame 230, a gear 240, a first limiting bolt 251, a second limiting bolt 252, a first buffer 261, a second buffer 262, a support shaft 271, a slider 272, multiple positioning blocks 280, and a base 290.

[0084] refer to Figure 2In this embodiment, the sensor body 120 can pass through and extend out of the first through hole 232 described below; the worktable 310 is used to abut against the end of the sensor 100 extending out of the first through hole 232 to avoid the sensor 100 moving along the height direction during the marking process, resulting in inaccurate marking position. The marking machine 320 is located directly above the worktable 310 and is used to mark the sensor body 120.

[0085] refer to Figure 3 , Figure 4 In this embodiment, the support frame 210 is along the length direction ( Figure 3 Extending along the length direction (in the X direction), the support frame 210 has a first end 211 and a second end 212. Both the first end 211 and the second end 212 are rectangular plate-like structures, and the first end 211 and the second end 212 are arranged opposite to each other.

[0086] In some possible implementations, the shapes of the first end 211 and the second end 212 include, but are not limited to, rectangular plate-like structures, and can be trapezoidal, elliptical, square, or other plate-like structures.

[0087] refer to Figure 3 , Figure 4 In this embodiment, the rack 220 is connected to the support frame 210 in a manner that allows it to move along its length. Specifically, the rack 220 is connected to the support frame 210 as follows: a support shaft 271 extends along its length and is mounted on the support frame 210. A slider 272 is sleeved on the support shaft 271, and the slider 272 can move along the support shaft 271 and is fixedly connected to the rack 220.

[0088] In some possible implementations, the driving connection between the rack 220 and the support frame 210 includes, but is not limited to, the sliding engagement between the slider 272 and the support shaft 271, or it can be achieved by using a lead screw and nut pair, a gear and rack pair, or a linear module driven by a linear motor.

[0089] refer to Figure 3 , Figure 4 In this embodiment, the rack 220 and the first end 211 and the second end 212 are in the width direction ( Figure 3 The racks (in the Y direction) are staggered to prevent interference with the support frame 210 when the rack 220 moves along its length. The limiting block 221 is located at the end of the rack 220 near the first end 211.

[0090] refer to Figure 3 and combined Figure 6 , Figure 7 In this embodiment, the rack 220 has a first position and a second position. (See reference...) Figure 3 , Figure 4This is a schematic diagram of rack 220 in the first position. In the first position, the front face 121 of rack 220 faces the positive direction in the height direction. Figure 3 middle A direction); Figure 6 , Figure 7 This is a schematic diagram of rack 220 in the second position, where the reverse side 122 of rack 220 faces the positive direction in the height direction.

[0091] refer to Figure 3 , Figure 4 , Figure 5 In this embodiment, the support frame 230 is along the height direction ( Figure 3 Extending in the Z direction, it is fixedly connected to the support frame 210 by welding. Along the width direction, the support frame 230 has a groove 231 on the side near the support frame 210, and the bottom wall 2311 of the groove 231 has a first through hole 232, which penetrates the support frame 230 along the width direction.

[0092] In some possible implementations, the connection between the support frame 230 and the bearing frame 210 may include, but is not limited to, welding, bolt fastening, or pin positioning, as long as a fixed connection can be achieved. This application does not limit this aspect.

[0093] refer to Figure 3 , Figure 4 In this embodiment, the gear 240 is disposed in the groove 231, meshes with the rack 220, and is rotatably connected to the groove 231. The gear 240 is provided with a mounting groove 241, which is adapted to the shape of the mounting plate 110; the gear 240 is provided with a second through hole 242, which penetrates the gear 240 along the width direction, and the sensor body 120 passes through the first through hole 232 and the second through hole 242. The first through hole 232 and the second through hole 242 are coaxial circular through holes.

[0094] In some possible implementations, the shapes of the first through hole 232 and the second through hole 242 are not limited to circles, but can be elliptical, square, arc, etc., as long as they can allow the sensor body 120 to pass through. The implementation of this application does not limit this.

[0095] Sensor 100 is clamped onto gear 240. Sensor body 120 passes through and extends out of first through hole 232 and second through hole 242, marking the extended portion of sensor body 120. At this time, rack 220 is in the first position, with the front side 121 of sensor body 120 facing upwards and aligned with marking machine 320, completing front marking. Due to the meshing transmission between gear 240 and rack 220, the linear displacement of rack 220 can be converted into rotational motion of gear 240. Subsequently, drive rack 220 to move linearly to the second position, rack 220 drives gear 240 to rotate 180°, thereby driving sensor 100 to perform a 180° fixed-point flip, with the back side 122 of sensor body 120 facing upwards and aligned with marking machine 320, completing back marking. Finally, double-sided marking is completed in a single clamping, eliminating positioning errors caused by secondary clamping and improving processing accuracy and production efficiency.

[0096] refer to Figure 3 , Figure 4 In this embodiment, the support frame 210 is connected to the base 290 in a manner that allows it to move along the height direction. Specifically, the base 290 is equipped with a cylinder 291, and the base 290 and the support frame 210 are connected via the cylinder 291. The cylinder 291 extends and retracts along the height direction, causing the support frame 210 to move along the height direction. A slide rail (not shown in the figure) extending along the height direction can also be provided on the base 290 to further define the movement trajectory of the support frame 210.

[0097] In some possible implementations, the base 290 and the support frame 210 are connected by a cylinder 291, which can be a linear drive method using an electric push rod, a servo electric cylinder or a hydraulic cylinder. This application does not limit this implementation.

[0098] By adding a base 290 and forming a vertical sliding pair with the support frame 210, the overall height of the clamping device is made adjustable, allowing the sensor 100 to flexibly adapt to the working distance of different marking equipment specifications, thus improving the versatility of the device. Furthermore, since the sensor body 120 is an elliptical elongated structure, in the sensor's marking system 300, it needs to abut against the worktable 310 with either its front side 121 or its back side 122. If rotation of the sensor 100 is required, it must be raised to a certain height to allow the sensor body 120 to rotate, thereby preventing interference between the sensor 100 and the worktable 310 during the flipping process.

[0099] The working principle of the sensor marking system 300, combined with the sensor clamping device 200 described above, is as follows:

[0100] First, the sensor 100 is installed in the mounting slot 241 of the gear 240 and fixed by magnetic attraction 243. The sensor body 120 passes through and extends out of the first through hole 232 and the second through hole 242. The rack 220 is adjusted to the first position so that the sensor body 120 extends out of the gear 240 and abuts against the surface of the worktable 310. At this time, the reverse side 122 contacts the worktable 310, and the front side 121 of the sensor body 120 faces the positive direction in the height direction and faces the marking machine 320, thus completing the marking of the front side 121. Subsequently, cylinder 291 lifts the support frame 210, causing sensor 100 to detach from worktable 310 to a rotatable height; the drive rack 220 moves to the second position, and the rack 220 moves in a straight line, driving gear 240 to rotate. After gear 240 and sensor 100 rotate 180°, cylinder 291 descends and resets, causing the front side 121 of sensor 100 to abut against worktable 310. At this time, the back side 122 faces the height direction and is facing the marking machine 320, finally completing the marking on the back side 122. The entire process achieves double-sided marking of sensor 100 through a single clamping.

[0101] refer to Figure 6 , Figure 7 In this embodiment, the first limiting bolt 251 extends through the first end 211 along its length and has a first limiting surface 2511, which is located between the first end 211 and the limiting block 221 described below. The second limiting bolt 252 extends through the second end 212 along its length and has a second limiting surface 2521, which is located between the second end 212 and the limiting block 221 described below. When the rack 220 is in the first position, the limiting block 221 abuts against the first limiting surface 2511; when the rack 220 is in the second position, the limiting block 221 abuts against the second limiting surface 2521.

[0102] refer to Figure 6 , Figure 7 In this embodiment, the first limiting bolt 251 is threadedly connected to the first end 211 of the support frame 210, and the second limiting bolt 252 is threadedly connected to the second end 212 of the support frame 210. By rotating and adjusting the screw-in depth of the limiting bolt, its protrusion position in the length direction can be adjusted, thereby achieving mechanical limiting of the travel of the rack 220.

[0103] In some possible implementations, the connection between the first limiting bolt 251, the second limiting bolt 252 and the support frame 210 may include, but are not limited to, threaded connection, and may adopt an interference fit, pin locking or a combination of groove and set screw connection.

[0104] The first limiting bolt 251, the second limiting bolt 252, and the corresponding limiting surfaces limit the movement of the rack 220 to its first and second positions, respectively. Specifically, when the rack 220 moves to the first position, the limiting block 221 abuts against the first limiting surface 2511, preventing the rack 220 from continuing to move in that direction, thus determining the end point of the rack 220's stroke (i.e., the first position); when the rack 220 moves to the second position, the limiting block 221 abuts against the second limiting surface 2521, preventing the rack 220 from continuing to move in the opposite direction, similarly precisely limiting the end point position (i.e., the second position). This achieves mechanical limitation of the linear motion stroke of the rack 220, thereby ensuring the accuracy and consistency of the rotation angle of the gear 240 each time, and enabling both the front 121 and the back 122 of the sensor body 120 to be positioned to the preset position. This effectively avoids marking position deviations caused by overshoot or positioning drift, further improving the reliability and product yield of the double-sided marking process.

[0105] refer to Figure 6 , Figure 7 In this embodiment, the first buffer 261 extends through the first end 211 along the length direction and is spaced apart from the first limiting bolt 251. Along the length direction, the end of the first buffer 261 near the second end 212 extends beyond the first limiting surface 2511. The second buffer 262 extends through the second end 212 along the length direction and is spaced apart from the second limiting bolt 252. Along the length direction, the end of the second buffer 262 near the first end 211 extends beyond the second limiting surface 2521.

[0106] refer to Figure 6 , Figure 7 In this embodiment, both the first buffer 261 and the second buffer 262 are elastic buffers. In some possible embodiments, the first buffer 261 and the second buffer 262 may include, but are not limited to, elastic buffers, and may be equivalent structures with buffering functions such as hydraulic buffers, pneumatic buffers, or spring dampers.

[0107] By adding a first buffer 261 and a second buffer 262, both the first buffer 261 and the second buffer 262 can elastically extend and retract along their length. When the rack 220 moves to the first position, the limiting block 221 will first contact and compress the first buffer 261, absorbing most of the impact energy through the deformation of the first buffer 261, before contacting the first limiting bolt 251. When the rack 220 moves to the second position, the limiting block 221 will first contact and compress the second buffer 262, absorbing most of the impact energy through the deformation of the second buffer 262, before contacting the second limiting bolt 252. Thus, buffered limiting is achieved in both the first and second positions. That is, buffering damping is provided when the rack 220 approaches the end of its stroke, effectively absorbing the kinetic energy of the rack and mitigating the rigid impact between the limiting block 221 and the first or second limiting bolt 251.

[0108] refer to Figure 6 , Figure 7 In this embodiment, the first buffer 261 near the second end 212 and the second buffer 262 near the first end 211 are both provided with rubber. In some possible embodiments, the material provided at the ends includes, but is not limited to, rubber, and may be a material with cushioning properties such as polyurethane, silicone, or engineering plastics. Alternatively, no cushioning material may be provided at the ends.

[0109] By incorporating rubber components at the ends of the first buffer 261 and the second buffer 262, the buffering performance is further optimized. The rubber material, with its high damping characteristics and elastic deformation capacity, effectively attenuates impact energy. This not only enhances the protection of the sensor 100 and reduces the risk of wear, but also further suppresses noise.

[0110] refer to Figure 6 , Figure 7 In this embodiment, four rectangular plate-shaped positioning blocks 280 are evenly distributed around the groove 231. A portion of each positioning block 280 is fixedly connected to the support frame 230, and another portion protrudes from the groove 231 and is spaced apart from the gear 240 along the width direction.

[0111] In some possible implementations, the number of positioning blocks 280 includes, but is not limited to, four; it can be two, three, eight, or more. The shape of the positioning blocks 280 includes, but is not limited to, rectangles; it can be elliptical, trapezoidal, square, or other plate-like structures. The arrangement can also be non-uniform, as long as it can prevent the gear 240 from moving outward along the width direction; this application does not limit this.

[0112] By setting multiple positioning blocks 280 that are laterally spaced from the gear 240, a stable and reliable axial limit is provided for the gear 240. In this embodiment, the axial direction of the gear 240 is the width direction. The positioning blocks 280 effectively constrain the axial movement of the gear 240 under high-speed rotation or under stress, ensuring the stability of the meshing transmission between the gear 240 and the rack 220.

[0113] refer to Figure 6 , Figure 7 In this embodiment, the positioning block 280 and the support frame 230 are fixedly connected by screws. This facilitates the installation and removal of the gear 240. In some possible embodiments, the connection method between the two includes, but is not limited to, screw connection, riveting, bonding, or snap-fit ​​mechanical connection.

[0114] refer to Figure 8 In this embodiment, the gear 240 is provided with a magnetic attraction part 243, which is disposed in the mounting groove 241 and corresponds to the magnetic material of the mounting plate 110; the gear 240 is fixedly connected to the mounting plate 110 through the magnetic attraction part 243. The magnetic attraction part 243 is cylindrical and is adapted to the shape of the bushing 111, and is disposed in the bushing 111.

[0115] In some possible implementations, the shape of the magnetic part 243 may include, but is not limited to, a cylindrical shape, or a flat plate or an arc shape, as long as it can be attracted to and fix the sensor 100 with the magnetic material part of the sensor 100. The embodiments of this application do not limit this.

[0116] The sensor 100 is quickly clamped and disassembled by utilizing the adsorption between the magnetic suction part 243 and the magnetic mounting plate 110. This not only simplifies operation and significantly improves material changing efficiency, but also avoids component wear or surface damage that may be caused by traditional mechanical clamping.

[0117] refer to Figure 9 In this embodiment, the gear 240 is provided with a connecting part 244, which is cylindrical. The connecting part 244 is located on the side of the gear 240 close to the groove 231 along the width direction. The second through hole 242 passes through the connecting part 244 along the width direction. The connecting part 244 is provided in the first through hole 232, and the gear 240 and the support frame 230 are rotatably connected through the connecting part 244.

[0118] By providing a connecting part 244 on the gear 240, which serves as a through-hole channel for the sensor 100, the sensor body 120 remains in a non-contact state with the support frame 230 during the flipping process, effectively avoiding surface scratches and structural damage caused by relative movement or direct contact with the support frame 230.
