Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a height difference detection tooling. Background Technology

[0002] The application of new energy batteries in daily life and industry is becoming increasingly widespread. To meet the demand for large-scale battery production, battery production efficiency also needs to be continuously improved. Therefore, magnetic drive logistics lines are used to transport pallets carrying batteries, thereby increasing battery production efficiency.

[0003] In related technologies, to ensure the stability of pallet operation on a magnetic drive logistics line, it is necessary to ensure that the distance between each stator in the magnetic drive stator assembly and the pallet is appropriate, i.e., to reduce or eliminate the height difference between multiple stators. Therefore, before the magnetic drive logistics line starts operating, an aluminum plate is placed on the line to mimic the pallet arrangement. The aluminum plate is then pushed along the line, and after each push, measuring tools such as plug gauges are used to measure and determine the distance between the aluminum plate and the corresponding stator, in order to adjust the height of multiple stators and reduce or eliminate the height difference between them.

[0004] However, this measurement method is relatively cumbersome to operate and has low measurement efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a height difference detection fixture to improve the efficiency of detecting the height difference between multiple stators in a magnetic drive material flow line.

[0006] This application is achieved through the following technical solution.

[0007] This application provides a height difference detection fixture for detecting the height difference between multiple stators in a magnetic drive material flow line. The height difference detection fixture includes a support component, a ranging component, and an abutment component. The ranging component is disposed on the support component and includes a measuring body and a probe connected to the measuring body. The abutment component includes a fixed base and a sliding rod. The fixed base is fixed to the support component, and the sliding rod is slidably disposed on the fixed base. A first end of the sliding rod abuts against the probe, and a second end of the sliding rod is used to slide among the multiple stators. The measuring body is used to obtain the displacement of the probe driven by the sliding rod to confirm the height difference.

[0008] In the technical solution of this application embodiment, when measuring, the bearing component is placed on the conveyor line formed by multiple stators. At this time, the second end of the sliding rod will contact the stator, the first end of the sliding rod will abut against the probe, and the meter body will have an initial display value.

[0009] Then, the carrier assembly is pushed along the conveyor line formed by multiple stators. During the movement of the carrier assembly, the ranging component and the contact component also move. During this movement, when the sliding rod does not move, the display shows the initial reading, indicating that the distance between the stator and the carrier assembly's movement plane meets the requirements. When the sliding rod descends, it indicates that the distance between the stator and the carrier assembly's movement plane has increased, and the initial reading on the display increases, suggesting adjustment to reduce the distance between the stator and the carrier assembly's movement plane. When the sliding rod rises, it indicates that the distance between the stator and the carrier assembly's movement plane has decreased, and the initial reading on the display decreases, suggesting adjustment to increase the distance between the stator and the carrier assembly's movement plane. This adjustment of the height of the multiple stators reduces or eliminates the height difference between them.

[0010] With this setup, during the movement of the load-bearing component, the display can show the distance between the moving plane of the load-bearing component and the stator at the real-time position, so that the operator can observe and adjust it. This operation is more convenient and efficient, and can complete the detection of the entire conveyor line, thereby ensuring the stability of the pallet movement during the operation of the conveyor line.

[0011] In some embodiments of this application, there are multiple abutment components and multiple ranging components, with each abutment component corresponding to a multiple ranging component; when the second end of the sliding rod of the multiple abutment components is not in contact with the multiple stators, the second ends of the sliding rod of the multiple abutment components are flush.

[0012] By properly setting the positions of multiple contact components and multiple ranging components, the efficiency of detection can be improved.

[0013] In some embodiments of this application, along the direction in which multiple stators form a conveyor line, the carrier component is provided with at least two sequentially arranged abutting components; and / or, along the width direction of the conveyor line, the carrier component is provided with at least two sequentially arranged abutting components.

[0014] In this way, when the load-bearing component passes the junction of two adjacent stators, both stators can be detected simultaneously. This also facilitates comparison of the height difference between adjacent stators, allowing for adjustment to reduce or eliminate this difference, thus improving detection and adjustment efficiency. And / or, even if a single stator is tilted, it can be measured and adjusted using multiple abutment components positioned along the width of the conveyor line. This ensures the flatness of the individual stator and ultimately the flatness of all stators in the entire magnetic drive stator assembly, thereby guaranteeing the stability of the pallet operation.

[0015] In some embodiments of this application, along the direction of the multiple stators forming the conveyor lines, the abutment components are symmetrically arranged on both sides of the carrier component.

[0016] This not only facilitates the setting of the contact components, but also allows for the simultaneous detection of two adjacent stators in the direction where multiple stators form a conveyor line, with the minimum number of contact components required. This reduces costs and improves detection efficiency.

[0017] In some embodiments of this application, the support component is provided with a first mounting hole, and the fixing seat is provided with a second mounting hole that mates with the first mounting hole. Fasteners disposed in the first and second mounting holes are used to fix the fixing seat and the support component. This fastener connection facilitates the installation and removal of both the fixing seat and the support component.

[0018] In some embodiments of this application, the first mounting hole and / or the second mounting hole are strip-shaped holes.

[0019] With the above settings, when the position of the fixing seat on the bearing component is not appropriate, the fixing seat can be separated from the bearing component by tightening the fasteners. Then, the fixing seat can be moved along the extension direction of the slot opening to adjust its position. After adjustment, the fixing seat can be fixed to the bearing component using the fasteners.

[0020] In some embodiments of this application, the height difference detection fixture further includes a bracket connected to a support component, with the measuring device connected to the bracket. This allows the ranging component to be mounted on the support component via the connection between the measuring device and the bracket, facilitating its connection and installation without affecting the movement of the measuring head. Furthermore, the ranging component can be positioned appropriately by adjusting the position of the bracket.

[0021] In some embodiments of this application, the bracket includes a first connecting rod, a second connecting rod, a first locking part, and a second locking part. The first connecting rod is disposed on the support assembly. The second connecting rod is slidably disposed on the first connecting rod and is capable of sliding along the sliding direction of the sliding rod. The first locking part is used to unlock or lock the movement of the second connecting rod relative to the first connecting rod. The watch body is slidably disposed on the second connecting rod and is capable of sliding radially along the sliding rod. The second locking part is used to unlock or lock the movement of the watch body relative to the second connecting rod.

[0022] In this way, the movement of the second connecting rod relative to the first connecting rod can be unlocked by the first locking part, thereby adjusting the displacement of the second connecting rod in the sliding direction of the sliding rod. Since the watch body is mounted on the second connecting rod, the watch body is also adjusted. After adjustment, the movement of the second connecting rod relative to the first connecting rod is locked again by the first locking part, achieving fixation. Additionally, the movement of the watch body relative to the second connecting rod can be unlocked by the second locking part, thus adjusting the radial displacement of the watch body along the sliding rod. After adjustment, the movement of the watch body relative to the second connecting rod is locked again by the second locking part, achieving fixation. The position adjustment of the watch body is achieved through the cooperation of the second connecting rod and the first connecting rod, and the positioning and fixation of the watch body is achieved through the cooperation of the first and second locking parts, ensuring precise alignment of the probe and the abutment component, guaranteeing installation accuracy and measurement accuracy.

[0023] In some embodiments of this application, the second connecting rod includes: a first rod segment and a second rod segment arranged sequentially, the first rod segment being slidably disposed on the first connecting rod. The watch body is slidably disposed on the second rod segment. The bracket also includes an adjusting member and a rotating shaft, the second rod segment being oscillating relative to the first rod segment about the rotating shaft, the axis of the rotating shaft being parallel to the cross-section of the sliding rod. The adjusting member is used to adjust the oscillation of the second rod segment.

[0024] By dividing the second connecting rod into two parts, the first segment and the second segment, and adjusting the swing of the second segment relative to the first segment using an adjusting component, the pitch angle of the second segment is adjusted. This, in turn, adjusts the displacement of the ranging component in the sliding direction of the sliding rod, adjusts the contact degree between the probe and the first end of the sliding rod, and adjusts the initial display value of the meter body, thereby achieving fine-tuning of the position of the ranging component.

[0025] In some embodiments of this application, the ends of the first and second rod segments that are close to each other are respectively connected to a mounting plate and a contact plate. The mounting plate and the contact plate are arranged along the swing direction, and the contact plate can swing relative to the mounting plate about a rotation axis. The adjusting member includes a tightening part and a spring-loaded part. Along the swing direction, the tightening part and the spring-loaded part abut against the opposite sides of the contact plate. The tightening part can push forward or retract and cooperate with the spring-loaded part to adjust the swing of the contact plate.

[0026] With the above configuration, in the swing direction, the jacking and tightening part can be pushed in to drive the abutment plate to swing, thereby driving the second rod segment to swing and the ranging component to swing. Alternatively, the jacking and tightening part can be retracted to allow the spring-loaded part to drive the abutment plate to swing back. This allows adjustment of the pitch angle of the ranging component, enabling fine-tuning of the ranging component.

[0027] In some embodiments of this application, the springback portion includes an elastic clamping plate, the two ends of which abut against the mounting plate and the side of the abutment plate opposite to each other.

[0028] By abutting against the sides of the elastic clamping plate and the mounting plate and the abutment plate, the elastic clamping plate's rebound function is ensured while facilitating its installation.

[0029] In some embodiments of this application, the bracket is connected to a first adsorption element, and the support assembly is connected to a second adsorption element, wherein the first adsorption element and the second adsorption element are magnetically attracted to each other.

[0030] By setting the first and second adsorption components, it is easy to connect and disassemble the bracket and the load-bearing component, and it is also easy to connect and disassemble the ranging component and the load-bearing component.

[0031] In some embodiments of this application, the abutment component further includes an elastic element, one end of which is fixed relative to the fixed seat and the other end of which is fixed relative to the sliding rod. The elastic element undergoes elastic deformation to provide a force to the sliding rod in the direction close to the stator.

[0032] By incorporating an elastic element, when the load-bearing component moves on the conveyor line, the elastic element can apply a pushing or pulling force close to the stator direction to the sliding rod, thereby ensuring that the second end of the sliding rod is always in contact with the stator, thus guaranteeing the accuracy of the measurement.

[0033] In some embodiments of this application, the elastic element includes a spring. The sliding rod includes a rod body and a limiting block. The rod body is slidably disposed on the fixed base, and a first end of the rod body abuts against the probe. The limiting block is connected to the second end of the rod body. The spring is sleeved on the rod body and abuts against the limiting block and the fixed base.

[0034] With the above settings, since the spring abuts between the limiting block and the fixed seat and undergoes compressive elastic deformation, the spring can always provide a force close to the stator direction to the limiting block, so that the limiting block can always contact the stator, thereby ensuring the accuracy of the measurement. This setting facilitates the stable setting of the spring.

[0035] In some embodiments of this application, the abutting component further includes a rolling component disposed on the limiting block.

[0036] In this way, the rolling components and the stator make rolling contact, which makes it easier to push the load-bearing components and also protects the stator from damage.

[0037] In some embodiments of this application, the sliding rod is slidably disposed within a channel on the fixed base. The abutment assembly also includes a linear bearing, the inner bore of which extends in the same direction as the channel, the outer sleeve of which is fixed to the fixed base, the sliding rod passing through the inner bore of the linear bearing, and the peripheral wall surface of the sliding rod being adapted to the inner bore of the linear bearing.

[0038] Such linear bearings can restrict the sliding rod from rotating around its axis, ensuring that the sliding rod will not rotate during sliding and thus guaranteeing the stability of the measurement.

[0039] In some embodiments of this application, the first end of the sliding rod is provided with an abutment groove, and the end of the probe abuts against the abutment groove. Along the radial direction of the sliding rod, the abutment groove is used to limit the relative displacement between the probe and the sliding rod.

[0040] This ensures a stable contact between the sliding rod and the probe, preventing the probe from shifting during sliding, thus guaranteeing the reliability of the height difference detection fixture and the accuracy of the detection.

[0041] In some embodiments of this application, the sliding rod is provided with a first limiting part, and the fixed base is provided with a second limiting part. The first limiting part and the second limiting part are connected in cooperation to limit the sliding rod from rotating about its axial direction.

[0042] By cooperating with the first and second limiting parts, the sliding rod is restricted from rotating around its axis without affecting the sliding of the sliding rod, thereby ensuring the stability and accuracy of the measurement.

[0043] In some embodiments of this application, the first limiting portion includes a profile formed on the sliding rod. The second limiting portion includes an abutting block that abuts against the profile to restrict the sliding rod from rotating about its axial direction.

[0044] The sliding rod is restricted from rotating around its axis by the contact between the abutment block and the molded surface. The arrangement of the abutment block and the molded surface is relatively convenient and easy to implement in actual processing.

[0045] In some embodiments of this application, the carrier component has a hollow space.

[0046] By creating open spaces in the support component, its weight can be reduced without affecting its sliding on the conveyor line or the installation of the ranging and contact components. This allows for easier handling and movement of the height difference detection fixture by the operator, while ensuring its proper functioning. Furthermore, it reduces the raw material consumption in producing the support component, thereby lowering material costs. Attached Figure Description

[0078] The following is a detailed description of this application.

[0079] Currently, new energy batteries are being used more and more widely in daily life and industry. They are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0080] To meet the demands of mass production of batteries, battery manufacturing efficiency is paramount. This has led to the introduction of magnetic drive logistics lines, where trays slide along the line to carry batteries, and the magnetic drive system propels the trays. Because of the high transport speed of these lines, battery production efficiency can be guaranteed.

[0081] It is understandable that "battery" is a general term; a battery can refer to a single battery cell, a battery cell assembly, or a battery device.

[0082] In some examples, the battery cell can be a rechargeable battery, which refers to a battery cell that can be recharged after being discharged to activate the active materials and continue to be used.

[0083] The battery cell can be a lithium-ion battery cell, a sodium-ion battery cell, a sodium-lithium-ion battery cell, a lithium metal battery cell, a sodium metal battery cell, a lithium-sulfur battery cell, a magnesium-ion battery cell, a nickel-metal hydride battery cell, a nickel-cadmium battery cell, a lead-acid battery cell, etc., but the embodiments of this application are not limited to this.

[0084] In some examples, the battery cell can be a cylindrical battery cell, a prismatic battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries. This application does not have any particular limitations.

[0085] Specifically, such as Figure 1 As shown, in order to drive the pallet movement using the magnetic drive logistics line, a magnetic drive stator assembly 11 extending along the magnetic drive logistics line is provided, and the pallet is made magnetic. The magnetic pallet movement is driven by the cooperation between the magnetic drive stator assembly 11 and the magnetic pallet.

[0086] Based on production line requirements, the length of magnetic drive logistics lines is generally quite long, typically around one or two hundred meters. Therefore, the length of the magnetic drive stator assembly 11 set on the magnetic drive logistics line is also around one or two hundred meters. To facilitate the setting of the magnetic drive stator assembly 11, along the extension direction of the magnetic drive logistics line, the magnetic drive stator assembly 11 is generally divided into multiple stator segments 111. During actual assembly, the multiple stator segments 111 are spliced ​​together to form the final magnetic drive stator assembly 11.

[0087] However, since the magnetic drive stator assembly 11 is composed of multiple stator segments 111 spliced ​​together, the multiple stator segments 111 in the height direction ( Figure 1 There may be some installation deviation in the Z direction, which will cause the distance between part of the stator 111 and the moving plane of the magnetic tray to be unsuitable.

[0088] In the actual operation of the magnetic drive logistics line, the following problems will exist: if the distance between the magnetic tray and the stator 111 is too large, the magnetic field strength between the stator 111 and the magnetic tray will be too weak, and the magnetic tray may go out of control during operation. If the distance between the moving plane of the magnetic tray and the stator 111 is too close, the bottom surface of the magnetic tray may come into contact with the stator 111 and rub against it, which may cause the stator 111 to overheat and trigger an alarm.

[0089] Based on this, in related technologies, before the magnetic drive logistics line is in operation, an aluminum plate is designed and slidably placed on the magnetic drive logistics line, mimicking the setting of a magnetic tray, so that the bottom surface of the aluminum plate is opposite to the stator 111. Then, the aluminum plate is pushed along the magnetic drive logistics line. After each push, the distance between the stator 111 and the moving plane of the aluminum plate at the corresponding position is measured using measuring tools such as plug gauges. Generally, the distance between the upper surface a of the stator 111 and the bottom surface of the aluminum plate is measured. Then, the stator 111 with an unsuitable distance is adjusted to reduce or eliminate the height difference between multiple stators 111. This ensures that after the magnetic tray is placed on the magnetic drive logistics line, the distance between the moving plane of the magnetic tray and multiple stator segments 111 is appropriate, thereby ensuring the operational stability of the magnetic tray.

[0090] However, since the magnetic drive stator assembly 11 contains a large number of stators 111, the relevant technology generally adopts a sampling inspection method, that is, only the distance between a portion of the stator 111 and the moving plane of the aluminum plate is inspected. As a result, there will still be cases where the distance between a portion of the stator 111 and the moving plane of the aluminum plate does not meet the requirements. In other words, there will still be cases where the height difference between a portion of the stator 111 does not meet the requirements. As a result, when the magnetic drive logistics line is running, there may still be cases where the magnetic tray runs unstable or comes into contact with and rubs against the stator 111.

[0091] In addition, the operation of measuring tools such as plug gauges is relatively cumbersome, resulting in low detection efficiency.

[0092] Based on this, such as Figure 1 As shown, in some embodiments, this application provides a height difference detection fixture 2 for detecting the height difference between multiple stators 111 of a magnetic drive material line. The height difference detection fixture 2 includes a support component 21, a ranging component 22, and an abutment component 23. The ranging component 22 is disposed on the support component 21 and includes a measuring body 222 and a probe 221 connected to the measuring body 222. The abutment component 23 includes a fixed base 231 and a sliding rod 232. The fixed base 231 is fixed to the support component 21, and the sliding rod 232 is slidably disposed within the fixed base 231. The first end of the sliding rod 232 abuts against the probe 221, and the second end of the sliding rod 232 is used to slide among the multiple stators 111. The measuring body 222 is used to obtain the displacement of the probe 221 driven by the sliding rod 232 to confirm the height difference.

[0093] It is understandable that the multiple stators 111 of the magnetic drive logistics line are arranged sequentially along the conveying direction, and the multiple stators 111 can form the conveying line 1.

[0094] In some examples, the stator 111 has an upper surface a, and the second end of the sliding rod 232 is used to slide on the upper surfaces a of multiple stators 111. The height difference between the multiple upper surfaces a is adjusted by detecting the height difference between the multiple upper surfaces a and then reducing or eliminating the height difference between the multiple upper surfaces a.

[0095] For ease of understanding and illustration, the plane containing the upper surface a is defined as the XOY plane, where the X direction is the extension direction of the conveyor line 1 (the arrangement direction of the multiple stators 111), the Y direction is the width direction of the conveyor line 1, and the Z direction is the sliding direction of the sliding rod 232.

[0096] The following diagram illustrates the case where the XOY plane is parallel to the horizontal plane and the Z direction is perpendicular to the XOY plane. In this case, the Z direction is vertical, the first end of the sliding rod 232 is the upper end of the sliding rod 232, and the second end of the sliding rod 232 is the lower end of the sliding rod 232.

[0097] In some examples, the supporting component 21 is a regular structure such as a plate-like structure or a block-like structure, but it can also be an irregular structure, such as a support structure.

[0098] In some examples, the support component 21 includes a peripheral surface e disposed about the Z direction, and a bottom surface and a top surface disposed opposite each other along the Z direction. The bottom surface is opposite to and spaced apart from the stator 111, and the top surface is located on the side of the bottom surface away from the stator 111.

[0099] In some examples, the material of the support component 21 includes aluminum or copper. For example, the material of the support component 21 includes aluminum, which is lightweight and inexpensive, making it easy for operators to handle, push, and perform other operations on the support component 21.

[0100] In some examples, such as Figure 1 As shown, in the width direction of the conveyor line 1, the size of the carrier component 21 is adapted to the size of the pallet used to carry the workpiece. And / or, in the extension direction of the conveyor line 1, the size of the carrier component 21 is adapted to the size of the pallet used to carry the workpiece. In this way, the size of the carrier component 21 is similar to that of the pallet, which facilitates the movement of the carrier component 21 on the conveyor line 1 and facilitates stable measurement.

[0101] It is understandable that the workpiece can be a single battery cell, a single battery cell assembly, or a battery device.

[0102] In some examples, the ranging component 22 includes a dial indicator or a micrometer.

[0103] In some examples, the mounting base 231 can be a block structure or a support structure, etc., which can be set according to the needs.

[0104] For example, the fixing seat 231 can be disposed at any suitable position on the support component 21, such as on the peripheral surface e, top surface or bottom surface of the support component 21. Alternatively, a clearance through hole can be opened on the bottom surface of the support component 21, and the fixing seat 231 can be fixed in the clearance through hole, as long as the placement of the fixing seat 231 does not affect the sliding of the sliding rod 232.

[0105] In some examples, the sliding direction of the slider 232 can be perpendicular to the upper surface a, which facilitates the sliding and measurement of the slider 232. Of course, the sliding direction of the slider 232 can also form an acute angle with the upper surface a.

[0106] In some examples, the sliding rod 232 can be a rod-shaped structure extending along the Z direction. Alternatively, the sliding rod 232 can also be a bent rod-shaped structure, as long as it can slide in the Z direction, and the first end face of the sliding rod 232 abuts against the probe 221, and the second end of the sliding rod 232 contacts the upper surface a.

[0107] In some examples, the sliding rod 232 can be a cylindrical rod or a polygonal prism rod, etc., where the polygonal prism rod can be a cuboid rod, a pentagonal prism rod, or a hexagonal prism rod, etc. Of course, the sliding rod 232 can also be an irregular rod-shaped structure.

[0108] In some examples, a channel c is provided on the fixed base 231, the channel c extends along the Z direction, and the sliding rod 232 is disposed in the channel c. The sliding rod 232 is adapted to the channel c, so that the sliding rod 232 slides along the Z direction.

[0109] For example, channel c can be a through hole or a track, etc.

[0110] In a specific example, the dial indicator 222 is given an initial preload, such that the initial display value of the dial indicator 222 is the standard distance between the movement plane of the carrier component 21 and the upper surface a. As the carrier component 21 moves along the conveyor line 1, when the distance between the upper surface a and the movement plane of the carrier component 21 changes, the sliding rod 232 moves upward or downward, thereby causing the probe 221 to rise or fall. Since the dial indicator 222 can obtain the displacement of the probe 221, the initial display value on the dial indicator 222 will change. This change is equal to the change in distance between the upper surface a and the movement plane of the carrier component 21. In other words, the actual display value of the dial indicator 222 at this time is the actual distance between the upper surface a and the movement plane of the carrier component 21.

[0111] For example, when the initial display value of the watch body 222 is 2mm, and the sliding rod 232 moves upward by 0.5mm, the actual display value of the watch body 222 is 1.5mm. That is to say, the actual distance between the upper surface a and the moving plane of the bearing component 21 is 1.5mm, and the stator 111 needs to be adjusted downward.

[0112] When the initial display value of the dial indicator 222 is 2mm, and the sliding rod 232 moves downward by 0.5mm, the actual display value of the dial indicator 222 is 2.5mm. That is to say, the actual distance between the upper surface a and the moving plane of the bearing component 21 is 2.5mm, and the stator 111 needs to be adjusted upward.

[0113] With the above settings, when measuring, the carrier component 21 is placed on the conveyor line 1. At this time, the second end of the sliding rod 232 will contact the stator 111, the first end of the sliding rod 232 will abut against the probe 221, and the meter body 222 will have an initial display value.

[0114] Then, the carrier assembly 21 is pushed along conveyor line 1. During the movement of the carrier assembly 21, the ranging assembly 22 and the contact assembly 23 also move accordingly. During this movement, when the sliding rod 232 does not move up or down, the display body 222 always shows the initial reading, indicating that the distance between the stator 111 and the moving plane of the carrier assembly 21 meets the requirements. When the sliding rod 232 descends, it indicates that the distance between the stator 111 and the moving plane of the carrier assembly 21 has increased, and the initial reading on the display body 222 has increased, indicating that adjustment is needed to reduce the distance between the stator 111 and the moving plane of the carrier assembly 21. When the sliding rod 232 rises, it indicates that the distance between the stator 111 and the moving plane of the carrier assembly 21 has decreased, and the initial reading on the display body 222 has decreased, indicating that adjustment is needed to increase the distance between the stator 111 and the moving plane of the carrier assembly 21.

[0115] With this configuration, during the movement of the bearing component 21, the dial indicator 222 can display the distance between the moving plane of the bearing component 21 and the stator 111 at the real-time position, so that the operator can observe and make adjustments. This operation is more convenient and efficient, and can complete the detection of the entire conveyor line 1, thereby ensuring the stability of the pallet operation when the conveyor line 1 is running.

[0116] The number of abutment components 23 and ranging components 22 can be selected as needed. For example, there can be one abutment component 23 and one ranging component 22. Alternatively, there can be multiple abutment components 23 and multiple ranging components 22.

[0117] In some embodiments, such as Figure 2 As shown, there are multiple abutment components 23 and multiple ranging components 22, with each abutment component 23 corresponding to one ranging component 22. When the second end of the sliding rod 232 of the multiple abutment components 23 is not in contact with the stator 111, the second ends of the sliding rod 232 of the multiple abutment components 23 are flush.

[0118] The number of abutment components 23 can be two, corresponding to two ranging components 22. Alternatively, the number of abutment components 23 can be three, corresponding to three ranging components 22. Alternatively, the number of abutment components 23 can be four, corresponding to four ranging components 22. Alternatively, the number of abutment components 23 can be six, corresponding to six ranging components 22.

[0119] By using the above settings, multiple ranging components 22 can be used for measurement. By reasonably setting the positions of multiple contact components 23 and multiple ranging components 22, the measurement efficiency can be improved, and the needs of various working conditions can be met.

[0120] Based on this, the configuration of multiple abutment components 23 can be set as needed, as detailed below.

[0121] In some embodiments, such as Figure 3 As shown, along the direction in which the conveyor line 1 is formed by multiple stators 111 ( Figure 3 In the X direction), the bearing component 21 is provided with at least two abutment components 23 arranged in sequence.

[0122] In this context, the number of abutting components 23 along the direction in which multiple stators 111 form the conveyor line 1 can be two, three, four, or five, etc.

[0123] With the above configuration, when the carrier component 21 passes the junction of two adjacent stators 111, both adjacent stators 111 can be detected simultaneously. This also facilitates comparison of the height difference between the two adjacent stators 111, allowing for adjustment to reduce or eliminate the height difference, thus improving detection and adjustment efficiency. Furthermore, when the carrier component 21 moves to the end of the conveyor line 1, the above configuration ensures that the abutment component 23 can detect any stator 111 at any end of the conveyor line 1 without the carrier component 21 slipping off the conveyor line 1.

[0124] In other embodiments, such as Figure 4 As shown, along the width direction of conveyor line 1 ( Figure 4 In the Y direction), the bearing component 21 is provided with at least two abutment components 23 arranged in sequence.

[0125] It is understandable that the number of abutting components 23 along the width direction of the conveyor line 1 can be set according to the distance between two adjacent abutting components 23 and the width of the stator 111.

[0126] In some examples, the number of abutment components 23 provided on the carrier component 21 along the width direction of the conveyor line 1 can be two, three, four, or five, etc.

[0127] With the above settings, along the width direction of the conveyor line 1, multiple ranging components 22 can display the distance between the stator 111 at its location and the moving plane of the bearing component 21. Even if a single stator 111 is tilted, it can be measured and displayed by multiple abutment components 23 set along the width direction of the conveyor line 1, the degree of tilt can be judged and adjusted, thereby ensuring the flatness of a single stator 111, and ultimately ensuring the flatness of the stator 111 of the entire magnetic drive stator group 11, thereby ensuring the stability of the pallet operation.

[0128] In other embodiments, such as Figure 2As shown, along the direction in which the multiple stators 111 form the conveyor line 1, the carrier component 21 is provided with at least two sequentially arranged abutment components 23, and along the width direction of the conveyor line 1, the carrier component 21 is provided with at least two sequentially arranged abutment components 23.

[0129] In this way, when the carrier assembly 21 passes the junction of two adjacent stators 111, the two adjacent stators 111 can be detected simultaneously, improving detection efficiency. Furthermore, when the carrier assembly 21 moves to the end of the conveyor line 1, by providing at least two abutment components 23 along the direction in which the multiple stators 111 form the conveyor line 1, it can be ensured that the abutment components 23 can detect any stator 111 at any end of the conveyor line 1. Simultaneously, even if a single stator 111 is tilted, it can be measured and adjusted by the multiple abutment components 23 arranged along the width direction of the conveyor line 1, thereby ensuring the flatness of the single stator 111 and ultimately ensuring the flatness of the stators 111 of the entire magnetic drive stator assembly 11, thus ensuring the stability of the pallet operation.

[0130] Along the extension direction of the conveyor line 1, when there are at least two abutting components 23, the arrangement of the at least two abutting components 23 can be varied, such as uniform distribution, symmetrical distribution or random distribution.

[0131] In some embodiments, such as Figure 3 As shown, along the direction in which multiple stators 111 form the conveyor line 1, the abutment components 23 are symmetrically arranged on both sides of the bearing component 21.

[0132] It is understood that the carrier component 21 has a first center line extending along the width direction of the conveyor line 1, and the abutment component 23 is symmetrically arranged about the first center line.

[0133] This not only facilitates the setting of the contact component 23, but also allows for the simultaneous detection of two adjacent stators 111 with the minimum number of contact components 23 along the extension direction of the conveyor line 1, thereby reducing costs and improving detection efficiency.

[0134] In other embodiments, at least two abutment components 23 are evenly arranged along the direction in which the multiple stators 111 form the conveyor line 1, which can better measure one stator 111 or measure two adjacent stators 111 at the same time.

[0135] In this case, the abutting component 23 can be set on the bottom surface of the bearing component 21, or multiple clearance through holes can be opened on the bottom surface of the bearing component 21. The multiple clearance through holes are evenly arranged along the extension direction of the conveyor line 1, and the abutting component 23 is set in the clearance through holes, thereby achieving the even distribution of multiple abutting components 23.

[0136] Along the width of the conveyor line 1, the arrangement of at least two abutting components 23 can be varied, such as uniform distribution, symmetrical distribution or random distribution.

[0137] In some embodiments, such as Figure 4 As shown, at least two abutting components 23 are evenly distributed on the bearing component 21 along the width direction of the conveyor line 1. This allows for better measurement of the tilt of a single stator 111 along the width direction of the conveyor line 1, thus enabling better adjustment of the stator 111.

[0138] In other embodiments, at least two abutment components 23 are symmetrically arranged about a second center line of the carrier component 21 along the width direction of the conveyor line 1. This also allows for better measurement of a stator 111.

[0139] During measurement, the abutment component 23 serves as an intermediate component connecting the ranging component 22 and the stator 111. Its structure and position settings have a significant impact on the accuracy of the data measured by the ranging component 22. The structure and position settings of the abutment component 23 are described below.

[0140] Regarding the placement of the abutment component 23, it can be placed on the top surface, bottom surface, or peripheral surface e of the supporting component 21. This will be described in detail below.

[0141] In some embodiments, such as Figure 2 , Figure 5 As shown, the bearing component 21 has a peripheral surface e arranged around the Z direction, and the abutment component 23 is fixed on the peripheral surface e.

[0142] It is understandable that after the abutment component 23 is fixed on the peripheral surface e, the presence of the abutment component 23 should not affect the sliding of the carrier component 21 after the carrier component 21 is placed on the conveyor line 1. In addition, the abutment component 23 is fixed on the peripheral surface e, which means that the fixing seat 231 is fixed to the peripheral surface e.

[0143] In some examples, along the extension direction of the conveyor line 1, the abutment component 23 is fixed to one side of the support component 21, and along the width direction of the conveyor line 1, both ends of the support component 21 are slidably disposed with respect to the conveyor line 1. This ensures that the abutment component 23 does not affect the sliding of the support component 21, and also facilitates the placement of the abutment component 23 to allow the sliding rod 232 in the abutment component 23 to slide.

[0144] In some examples, the peripheral surface e is a vertical surface extending along the Z direction. Since the sliding rod 232 can slide along the Z direction, this further facilitates the setting of the sliding rod 232 and the fixed seat 231. Of course, the peripheral surface e can also be an inclined surface.

[0145] By fixing the abutment component 23 to the peripheral surface e of the support component 21, the abutment component 23 can avoid the support component 21. Except for the connection between the fixing seat 231 and the support component 21, other components in the abutment component 23 will not interfere with the support component 21. The abutment component 23 and the support component 21 do not need to be specially treated because of each other's existence, which facilitates the setting of the abutment component 23 and the realization of the sliding function of the sliding rod 232.

[0146] Of course, in other embodiments, an avoidance through hole can be opened on the bottom surface of the supporting component 21, and the abutting component 23 can be disposed in the avoidance through hole, thus achieving the placement of the abutting component 23.

[0147] In some embodiments, such as Figure 5 As shown, the support component 21 is provided with a first mounting hole, and the fixing seat 231 is provided with a second mounting hole f that mates with the first mounting hole. The fixing seat 231 and the support component 21 are fixed by fasteners provided in the first mounting hole and the second mounting hole f.

[0148] The number of fasteners, the first mounting hole, and the second mounting hole f can all be one.

[0149] Alternatively, there can be multiple fasteners, first mounting holes, and second mounting holes f, with each first mounting hole corresponding to one of the multiple second mounting holes f. For example, the number of fasteners, first mounting holes, and second mounting holes f can be two, three, four, or five, etc.

[0150] In some examples, the fastener can be a screw or a bolt, etc., whichever is more appropriate to the specific requirements.

[0151] In some examples, such as Figure 5 As shown, the fixing seat 231 is fixed to the peripheral surface e. At this time, the first mounting hole is opened on the peripheral surface e to fix the fixing seat 231.

[0152] For example, such as Figure 5 As shown, the fixed base 231 includes a base plate 2311 and a connecting block 2312 connected to each other. The second mounting hole f is opened on the base plate 2311. The base plate 2311 is fixed to the peripheral surface e. The connecting block 2312 is disposed on the side of the base plate 2311 away from the peripheral surface e. The sliding rod 232 is slidably disposed with the connecting block 2312. The base plate 2311 extends along the circumferential direction of the peripheral surface e.

[0153] Along the circumferential direction of the peripheral surface e, the size of the base plate 2311 can be larger than the size of the connecting block 2312, so that the connecting block 2312 and the base plate 2311 can avoid each other, which makes it easier to open a second mounting hole f on the base plate 2311, thereby facilitating the fixing of the base plate 2311 and the bearing component 21.

[0154] For example, along the circumferential direction of the peripheral surface e, the connecting block 2312 is connected to the middle of the base plate 2311, and a second mounting hole f is provided at both ends of the base plate 2311. This arrangement can ensure the fixed stability of the base plate 2311.

[0155] In addition, the base plate 2311 and the connecting block 2312 can be integrally formed, which can ensure the overall structural strength of the fixing seat 231 and avoid secondary processing. Of course, the base plate 2311 and the connecting block 2312 can also be separate structures.

[0156] The mounting base 231 is secured to the support assembly 21 using fasteners. When it is necessary to disassemble the mounting base 231, only the fasteners need to be removed. The fastener connection method facilitates the installation and removal of the mounting base 231.

[0157] In some embodiments, such as Figure 5 As shown, the first mounting hole and / or the second mounting hole f are strip-shaped holes.

[0158] In some examples, the opening of the slot extends in the Z direction, and the sliding direction of the sliding rod 232 is also in the Z direction. Thus, since the opening of the slot extends in the Z direction, if the distance between the fixed seat 231 and the stator 111 is not appropriate in the Z direction, the fixed seat 231 can be separated from the bearing assembly 21 by tightening the fasteners, then the fixed seat 231 can be moved into place, and finally the fixed seat 231 can be fixed to the bearing assembly 21.

[0159] In some examples, the first mounting hole is a circular hole, and the second mounting hole f is a strip hole. Alternatively, the first mounting hole is a strip hole, and the second mounting hole f is a circular hole. Or, both the first mounting hole and the second mounting hole f are strip holes. It is acceptable as long as at least one of the first mounting hole and the second mounting hole f is a strip hole.

[0160] Of course, the extension direction of the strip hole can also be the X direction or the Y direction, depending on the adjustment requirements of the mounting base.

[0161] With the above configuration, when the position of the fixing seat 231 on the bearing component 21 is not suitable, the fixing seat 231 can be separated from the bearing component 21 by tightening the fasteners. Then, the fixing seat 231 can be moved along the extension direction of the slot opening to adjust its position. After adjustment, the fixing seat 231 can be fixed to the bearing component 21 using the fasteners. This facilitates the adjustment of the position of the fixing seat 231.

[0162] Regarding the structure of the abutment component 23, the arrangement of the sliding rod 232 and the fixed seat 231 can be varied, and the abutment component 23 can also include other structures, which will be described in detail below.

[0163] In some embodiments, such as Figure 6 As shown, the central axis of the sliding rod 232 coincides with the direction of the movement path of the probe 221. In this way, the movement path of the probe 221 will be on the same line as the central axis of the sliding rod 232. When the sliding rod 232 and the probe 221 slide under the influence of force, it can ensure smooth movement of the sliding rod 232 and the probe 221 in the Z direction, thereby ensuring the accuracy of the measurement by the probe 221.

[0164] In some embodiments, such as Figure 5 , Figure 6 As shown, the abutment assembly 23 also includes an elastic element 233. One end of the elastic element 233 is fixed relative to the fixed seat 231, and the other end of the elastic element 233 is fixed relative to the sliding rod 232. The elastic element 233 undergoes elastic deformation to provide a force to the sliding rod 232 in the direction close to the stator 111.

[0165] It is understandable that the setting of the elastic element 233 should not affect the sliding of the sliding rod 232.

[0166] The elastic element 233 may include a spring or an elastic pad, etc.

[0167] In some examples, the elastic element 233 undergoes elastic deformation along the Z direction, so that the force exerted by the elastic element 233 on the sliding rod 232 is along the Z direction. The direction of this force is consistent with the sliding direction of the sliding rod 232, which can achieve the best preload effect.

[0168] In other examples, the direction of elastic deformation of the elastic element 233 can also be at an acute angle to the Z direction, as long as the force applied by the elastic element 233 to the sliding rod 232 is close to that of the stator 111.

[0169] By setting the elastic element 233, when the bearing assembly 21 moves on the conveyor line 1, the elastic element 233 can apply a pushing or pulling force to the sliding rod 232 in a direction close to the stator 111, so that the second end of the sliding rod 232 is always in contact with the stator 111, thus ensuring the accuracy of the detection.

[0170] During the measurement process, whether the elastic element 233 undergoes compressive deformation or tensile deformation, it can provide the sliding rod 232 with a force in the direction close to the stator 111. This mainly depends on the setting position and connection relationship of the elastic element 233.

[0171] Based on this, in some embodiments, such as Figure 7 As shown, the elastic element 233 includes a spring 2331. The sliding rod 232 includes a rod body 2321 and a limiting block 2322. The rod body 2321 is slidably disposed on the fixed base 231, and the first end of the rod body 2321 abuts against the probe 221. The limiting block 2322 is connected to the second end of the rod body 2321. The spring 2331 is sleeved on the rod body 2321 and abuts against the limiting block 2322 and the fixed base 231.

[0172] It is understandable that the spring 2331 abuts against the limiting block 2322 and the fixed seat 231, indicating that the spring 2331 is undergoing compression deformation at this time, and the abutting block 2331 is subjected to a thrust in the Z direction.

[0173] It should be explained that when the bearing assembly 21 moves along the conveyor line 1, the second end of the sliding rod 232 contacts the stator 111 through the limiting block 2322.

[0174] In some examples, the sliding rod 232 slides vertically, in which case the first end of the rod 2321 is the upper end and the second end of the rod 2321 is the lower end.

[0175] With the above settings, when measuring, the limiting block 2322 contacts the stator 111, and the limiting block 2322 and the rod 2321 slide together to drive the probe 221 to move, thereby realizing the measurement.

[0176] Since the fixed base 231 and the bearing assembly 21 are fixed, the fixed base 231 will not move in the Z direction, while the limiting block 2322 will move in the Z direction. Because the spring 2331 abuts against the limiting block 2322 and the fixed base 231 and undergoes compressive elastic deformation, the spring 2331 can always provide a thrust in the Z direction to the limiting block 2322, ensuring that the limiting block 2322 can always contact the stator 111, thereby guaranteeing measurement accuracy. Furthermore, since the spring 2331 is sleeved on the rod 2321, the rod 2321 can provide radial limitation for the spring 2331, ensuring that the spring 2331 is stably positioned between the limiting block 2322 and the fixed base 231.

[0177] In other embodiments, along the deformation direction of the elastic element 233, one end of the elastic element 233 is connected to the fixed base 231, and the other end of the elastic element 233 is connected to the sliding rod 232. When the second end of the sliding rod 232 contacts the stator 111, the elastic element 233 undergoes tensile deformation, and the tension generated by the stretching of the elastic element 233 is downward. In this way, the elastic element 233 can also be used to provide a force to the sliding rod 232 that approaches the stator 111.

[0178] In some embodiments, such as Figure 7 As shown, the abutment component 23 also includes a rolling component 234 disposed on the limiting block 2322.

[0179] In some examples, the rolling assembly 234 is connected to the limiting block 2322 and can rotate at least about the width of the conveyor line 1. When the carrier assembly 21 moves along the conveyor line 1, the limiting block 2322 contacts the stator 111 through the rolling assembly 234.

[0180] It is understandable that, in order to ensure that the limiting block 2322 contacts the stator 111 through the rolling component 234, the lowest end of the rolling component 234 needs to protrude beyond the lowest side of the limiting block 2322 in the Z direction.

[0181] The rolling component 234 can be connected to the lower or side of the limiting block 2322.

[0182] In some examples, the rolling assembly 234 includes a roller 2341, the axis of rotation of which extends along the width of the conveyor line 1.

[0183] In other examples, the scrolling component 234 includes a ball that can rotate 360°.

[0184] By connecting the rolling component 234 to the limit block 2322, the rolling component 234 can roll on the stator 111 during the movement of the bearing component 21 along the conveyor line 1. Since the rolling component 234 and the stator 111 are in rolling contact, friction can be reduced and more effort is required during the pushing of the bearing component 21. In addition, the stator 111 can be protected from damage.

[0185] Based on this, in some embodiments, such as Figure 7 As shown, the rolling assembly 234 includes a roller 2341, the rotation axis of which extends along the width direction of the conveyor line 1. The limiting block 2322 includes a limiting plate A1 and a connecting plate A2, the limiting plate A1 being connected to the second end of the rod 2321. A spring 2331 abuts against the limiting plate A1 and the fixed seat 231. The connecting plate A2 is connected to the second end of the limiting plate A1. Along the rotation axis of the roller 2341, the roller 2341 is connected to one side of the connecting plate A2.

[0186] It is understood that the roller 2341 includes a roller part and a rolling shaft. The rolling shaft extends along the width direction of the conveyor line 1 and is connected to the connecting plate A2. The roller part is sleeved on the rolling shaft to rotate around the rolling shaft.

[0187] In addition, in order to ensure that the abutment block B2 can contact the stator 111 through the roller 2341, the bottom end of the roller 2341 needs to protrude beyond the bottom side of the connecting plate A2 in the Z direction.

[0188] With the above configuration, the limiting plate A1 cooperates with the fixed base 231 to limit the movement of the spring 2331, while the connecting plate A2 connects to the roller 2341 to the sliding rod 232. Along the extension direction of the roller 2341's rotation axis, since the roller 2341 is located on one side of the connecting plate A2, the connecting plate A2 will not interfere with the installation of the roller 2341, thus facilitating its installation.

[0189] In other embodiments, such as Figure 8 As shown, the limiting block 2322 includes a limiting plate A1 and two connecting plates A2. The limiting plate A1 is connected to the second end of the rod 2321. A spring 2331 abuts against the limiting plate A1 and the fixed base 231. The connecting plates A2 are connected to the second end of the limiting plate A1, and the two connecting plates A2 are arranged at intervals along the width direction of the conveyor line 1. A roller 2341 is disposed between the two connecting plates A2, and the rotation axis of the roller 2341 extends along the width direction of the conveyor line 1. This also allows for the installation and setting of the roller 2341.

[0190] In some embodiments, such as Figure 7 , Figure 8As shown, the load-bearing center of the rolling assembly 234 is located on the central axis of the rod 2321.

[0191] In some examples, where roller 2341 is connected to one side of connecting plate A2 along its rolling axis, the bearing center of rolling assembly 234 can be located at the midpoint between roller 2341 and connecting plate A2. When roller 2341 is positioned between two connecting plates A2, the bearing center of rolling assembly 234 can be located at the center of the rolling axis of roller 2341 along the width of conveyor line 1.

[0192] In this way, the force applied by the rolling component 234 to the rod 2321 is along the central axis of the rod 2321. This force will not generate a component force in other directions, which can ensure that the rod 2321 slides more smoothly, thereby ensuring that the detection results of the ranging component 22 are more accurate.

[0193] In some embodiments, such as Figure 7 , Figure 9 As shown, the sliding rod 232 is slidably disposed within the channel c of the fixed base 231. The abutment assembly 23 also includes a linear bearing 235, the inner bore of which extends in the same direction as the channel c. The outer sleeve of the linear bearing 235 is fixed to the fixed base 231. The sliding rod 232 passes through the inner bore of the linear bearing 235, and the peripheral wall surface of the sliding rod 232 is adapted to the inner bore of the linear bearing 235.

[0194] It is understandable that when the sliding rod 232 includes the rod body 2321 and the limiting block 2322, the rod body 2321 passes through the inner hole of the linear bearing 235, and the peripheral wall surface of the rod body 2321 is adapted to the inner hole of the linear bearing 235.

[0195] The linear bearing 235 can be fixed to the mounting base 231 by means of snap-fit, screw fastening or welding.

[0196] In some examples, such as Figure 7 As shown, the linear bearing 235 is located outside the fixed seat 231. Along the extension direction of the channel c, the linear bearing 235 is located on one side of the fixed seat 231 and is fixed to the fixed seat 231.

[0197] For example, the linear bearing 235 is located on the side of the mounting base 231 away from the spring 2331, so that there is no interference between the linear bearing 235 and the spring 2331, which facilitates their respective settings.

[0198] In other examples, the linear bearing 235 is located within a mounting base 231, the mounting base 231 having a space formed inside to accommodate the linear bearing 235, such that the inner bore of the linear bearing 235 communicates with the middle of the channel c.

[0199] By mounting the linear bearing 235 onto the sliding rod 232, the sliding rod 232 can slide within the linear bearing 235 along the Z-direction. Since the linear bearing 235 restricts the sliding rod 232 from rotating around its axial direction, the sliding rod 232 will not rotate during sliding, thus ensuring measurement stability. Especially when a roller 2341 is provided at the second end of the sliding rod 232, the linear bearing 235 ensures that the rotation axis of the roller 2341 is always along the width direction of the conveyor line 1, thereby ensuring that the roller 2341 and the stator 111 are always in rolling contact.

[0200] In some embodiments, such as Figure 10 As shown, the sliding rod 232 is provided with a first limiting part 2324, and the fixed base 231 is provided with a second limiting part 2313. The first limiting part 2324 and the second limiting part 2313 are connected in cooperation to restrict the sliding rod 232 from rotating around its axis.

[0201] In some examples, the abutment component 23 of this application is provided with both a first limiting part 2324 and a second limiting part 2313, as well as a linear bearing 235. In this way, both can limit the sliding rod 232 from rotating around its axis. The two can complement each other and provide protection for each other. In addition, the stability and accuracy of the measurement can be further improved.

[0202] With the cooperation of the first limiting part 2324 and the second limiting part 2313, the sliding rod 232 is restricted from rotating around its axis without affecting the sliding of the sliding rod 232, thereby ensuring the stability and accuracy of the measurement.

[0203] Based on this, in some embodiments, such as Figure 10 As shown, the first limiting part 2324 includes a profile B1 formed on the sliding rod 232. The second limiting part 2313 includes an abutting block B2, which abuts against the profile B1 to restrict the sliding rod 232 from rotating about its axial direction.

[0204] Among them, surface B1 can be a flat surface or a curved surface.

[0205] In some examples, the profile B1 extends along the Z direction, so that after the abutting block B2 abuts against the profile B1, the sliding rod 232 can be restricted from rotating about its axis. In addition, the engagement between the abutting block B2 and the profile B1 will not affect the sliding rod 232 sliding along the Z direction.

[0206] In some examples, multiple surfaces B1 can be set, and these multiple surfaces B1 are set sequentially around the Z direction. Correspondingly, multiple abutment blocks B2 are also set, with each abutment block B2 corresponding to one of the multiple surfaces B1, and each abutment block B2 abuts against the corresponding surface B1.

[0207] For example, multiple surfaces B1 are spaced apart around the Z direction. Alternatively, multiple surfaces B1 are connected sequentially around the Z direction.

[0208] With the above configuration, since the abutment block B2 abuts against the profile B1, the cooperation between the abutment block B2 and the profile B1 can restrict the sliding rod 232 from rotating around its axial direction. The configuration of the abutment block B2 and the profile B1 is relatively convenient and easy to implement in actual processing.

[0209] In other embodiments, the first limiting portion 2324 includes a protrusion, and the second limiting portion 2313 includes a groove that extends through the fixing seat 231 along the Z direction. The protrusion extends into the groove and is oriented around the Z direction, contacting the sidewall of the groove. This also allows the sliding rod 232 to be restricted from rotating about its axial direction while ensuring that the sliding rod 232 slides along the Z direction.

[0210] In some embodiments, such as Figure 9 As shown, the first end of the sliding rod 232 has a flange 2323, and the radial outer contour of the flange 2323 is larger than the cross-section of the channel c.

[0211] It is understandable that during measurement, in order to avoid the flange 2323 affecting the descent of the sliding rod 232 and to ensure that the second end of the sliding rod 232 is always in contact with the stator 111, when the second end of the sliding rod 232 is in contact with the stator 111 and the ranging component 22 displays the initial display value, the flange 2323 needs to have a preset distance from the upper surface of the fixed base 231. This preset distance needs to ensure that the sliding rod 232 can descend and that the second end of the sliding rod 232 is in contact with the stator 111 after the distance between the stator 111 and the moving plane of the bearing component 21 increases, so as to perform the measurement.

[0212] In some examples, profile B1 is formed on flange 2323.

[0213] By providing a flange 2323 at the first end of the sliding rod 232, the flange 2323 can prevent the sliding rod 232 from sliding out of the channel c after the height difference detection fixture 2 is removed from the conveyor line 1, thereby ensuring the overall reliability of the height difference detection fixture 2.

[0214] In some embodiments, such as Figure 7 As shown, the first end of the sliding rod 232 has an abutment groove d, and the end of the probe 221 abuts in the abutment groove d. Along the radial direction of the sliding rod 232, the abutment groove d is used to limit the relative displacement between the probe 221 and the sliding rod 232.

[0215] The abutment groove d can be a regular groove structure such as a cuboid groove or a cylindrical groove. Of course, the abutment groove d can also be an irregular groove structure.

[0216] In some examples, the abutment groove d is provided on the flange 2323.

[0217] With the above configuration, since the abutment groove d has an inner peripheral wall, after the probe 221 extends into the abutment groove d, the peripheral wall of the probe 221 contacts or has a certain gap with the inner peripheral wall of the abutment groove d. The inner peripheral wall of the abutment groove d can prevent the probe 221 from moving radially in the sliding rod 232 to a certain extent. This ensures that the sliding rod 232 and the probe 221 establish a stable abutment relationship, and avoids the probe 221 from deviating during the sliding process, thereby ensuring the reliability of the height difference detection fixture 2 and ensuring the accuracy of the detection.

[0218] In addition to the abutment component 23, the configuration of components such as the bearing component 21 and the ranging component 22 also affects the actual operation. The bearing component 21 and the ranging component 22 are described below.

[0219] For the carrier component 21, in some embodiments, such as Figure 11 As shown, a hollow space g is formed on the supporting component 21.

[0220] It is understandable that the setting of the hollow space g should not affect the installation of the ranging component 22 and the abutment component 23.

[0221] The hollow space g can be a weight-reducing hole or cavity opened on the supporting component 21.

[0222] By providing a hollow space g on the support component 21, the weight of the support component 21 can be reduced without affecting its sliding on the conveyor line 1, or the installation of the ranging component 22 and the abutment component 23. This allows for easy handling or pushing of the height difference detection fixture 2 by the operator, while ensuring its proper functioning. Furthermore, it reduces the raw material consumption in producing the support component 21, thereby lowering material costs.

[0223] Based on this, in some embodiments, such as Figure 11 As shown, the hollow space g includes multiple weight-reducing holes g1, which are evenly distributed on the bottom surface of the support component 21 to make the weight of the support component 21 uniform within its extension range.

[0224] In some examples, multiple weight-reducing holes g1 are arranged in an array along the bottom outer contour of the support component 21 to be evenly distributed on the support component 21.

[0225] For example, if the bottom outer contour of the support component 21 is square, then the multiple weight-reducing holes g1 are also arranged in a square array on the bottom surface of the support component 21. Alternatively, if the bottom outer contour of the support component 21 is circular, then the multiple weight-reducing holes g1 are also arranged in a circular array on the bottom surface of the support component 21.

[0226] It is understandable that the weight reduction hole g1 can be a blind hole or a through hole.

[0227] The number of weight-reducing holes g1 can be one. Alternatively, the number of weight-reducing holes g1 can be multiple, for example, two, three, four, five, ten, or sixteen, etc.

[0228] In addition, the weight-reducing hole g1 can be a regular shape, such as a cuboid hole or a cylindrical hole, which facilitates the machining of the weight-reducing hole g1. Alternatively, the weight-reducing hole g1 can also be an irregularly shaped weight-reducing hole g1.

[0229] With the above settings, within the extension range of the bearing component 21, the weight reduction per unit volume of the bearing component 21 by the weight reduction hole g1 is consistent, so the weight within the extension range of the bearing component 21 is uniform. Thus, when the bearing component 21 is pushed to move along the conveyor line 1, the bearing component 21 can be prevented from shifting, which facilitates the movement of the bearing component 21 on the conveyor line 1 and ensures the accuracy of the measurement.

[0230] In other embodiments, the hollow space g includes a cavity located inside the support component 21.

[0231] The cavity can be a regular three-dimensional space such as a cube or a sphere. Alternatively, the cavity can also be an irregular three-dimensional space.

[0232] Alternatively, there can be one cavity. Or, there can be multiple cavities, which can be set up independently of each other.

[0233] For the ranging component 22, the ranging component 22 needs to be connected to the carrier component 21. The ranging component 22 and the carrier component 21 can be directly connected or indirectly connected.

[0234] In some embodiments, such as Figure 13 As shown, the height difference detection fixture 2 also includes a bracket 24, which is disposed on the bearing component 21, and the meter body 222 is connected to the bracket 24.

[0235] It is understandable that the number of brackets 24 should correspond one-to-one with the number of ranging components 22, with one ranging component 22 connected to the corresponding bracket 24.

[0236] The bracket 24 can be connected to the upper surface of the support component 21. The upper surface of the support component 21 has a large area, which facilitates the installation of the bracket 24 and does not affect the movement of the support component 21.

[0237] In some examples, the support 24 may be a structure consisting of a second connecting rod 242 and a first connecting rod 241.

[0238] By setting the bracket 24, the ranging component 22 can be connected to the bearing component 21 through the bracket 24. In this way, by changing the position of the bracket 24, the ranging component 22 can be set in a suitable position, so that the measuring head 221 of the ranging component 22 can abut against the first end of the sliding rod 232 in the abutment component 23, which can facilitate the arrangement of the ranging component 22 and the abutment component 23.

[0239] Based on this, in some embodiments, such as Figure 3 , Figure 13 As shown, the bracket 24 includes a first connecting rod 241, a second connecting rod 242, a first locking part 243, and a second locking part 244. The first connecting rod 241 is disposed on the support assembly 21. The second connecting rod 242 is slidably disposed on the first connecting rod 241 and can slide along the sliding direction of the sliding rod 232. The first locking part 243 is used to unlock or lock the movement of the second connecting rod 242 relative to the first connecting rod 241. The watch body 222 is slidably disposed on the second connecting rod 242 and can slide radially along the sliding rod 232. The second locking part 244 is used to unlock or lock the movement of the watch body 222 relative to the second connecting rod 242.

[0240] The first connecting rod 241 can be a cylindrical rod or a polygonal prism rod, etc., and the polygonal prism rod can be a cuboid rod, a pentagonal prism rod, or a hexagonal prism rod, etc. Of course, the first connecting rod 241 can also be an irregular rod-shaped structure.

[0241] The second connecting rod 242 can be a cylindrical rod or a polygonal prism rod, etc., wherein the polygonal prism rod can be a cuboid rod, a pentagonal prism rod, or a hexagonal prism rod, etc. Of course, the second connecting rod 242 can also be an irregular rod-shaped structure.

[0242] In some examples, such as Figure 3 , Figure 13 As shown, the first locking part 243 includes a first clamp, and the second connecting rod 242 is connected to the first clamp. The first clamp is sleeved on the first connecting rod 241. By adjusting the first stud on the first clamp, the tightness of the first clamp sleeved on the first connecting rod 241 can be changed, so as to unlock or lock the movement of the second connecting rod 242 relative to the first connecting rod 241.

[0243] In other examples, the first locking part 243 may also include a first threaded abutment post, and a second connecting rod 242 sleeved on the first connecting rod 241. The second connecting rod 242 has a first threaded hole, so that the first threaded abutment post is threadedly connected to the first threaded hole. By rotating the first threaded abutment post, the first threaded abutment post can be separated from or abutted against the first connecting rod 241, thereby unlocking or locking the movement of the second connecting rod 242 relative to the first connecting rod 241.

[0244] In some examples, such as Figure 3 , Figure 13 As shown, the second locking part 244 includes a second clamp, the watch body 222 is connected to the second clamp, the second clamp is sleeved on the second connecting rod 242, and by adjusting the second stud on the second clamp, the tightness of the second clamp sleeved on the second connecting rod 242 is changed, so as to unlock or lock the movement of the watch body 222 relative to the second connecting rod 242.

[0245] In other examples, the second locking part 244 may also include a second threaded abutment post, the watch body 222 is sleeved on the second connecting rod 242, and the ranging component 22 has a second threaded hole, so that the second threaded abutment post is threadedly connected to the second threaded hole, so that by rotating the second threaded abutment post, the second threaded abutment post can be separated from or abutted against the second connecting rod 242, thereby unlocking or locking the movement of the watch body 222 relative to the second connecting rod 242.

[0246] With the above configuration, the movement of the second connecting rod 242 relative to the first connecting rod 241 can be unlocked by the first locking part 243, thereby adjusting the displacement of the second connecting rod 242 in the sliding direction of the sliding rod 232. Since the watch body 222 is mounted on the second connecting rod 242, the watch body 222 is also adjusted. After adjustment, the first locking part 243 is used to lock the movement of the second connecting rod 242 relative to the first connecting rod 241, thus achieving fixation.

[0247] Furthermore, the movement of the dial body 222 relative to the second connecting rod 242 can be unlocked by the second locking part 244, thus allowing adjustment of the radial displacement of the dial body 222 along the sliding rod. After adjustment, the movement of the dial body 222 relative to the second connecting rod 242 is locked by the second locking part 244, achieving fixation. The position adjustment of the dial body 222 is achieved through the cooperation of the second connecting rod 242 and the first connecting rod 241, and the positioning and fixation of the dial body 222 is achieved through the cooperation of the first locking part 243 and the second locking part 244, so as to ensure precise alignment between the probe 221 and the abutment component 23, ensuring installation accuracy and measurement accuracy.

[0248] Based on this, in some embodiments, such as Figure 13As shown, the second connecting rod 242 includes a first rod segment 2421 and a second rod segment 2422 arranged sequentially. The first rod segment 2421 is slidably disposed on the first connecting rod 241. The watch body 222 is slidably disposed on the second rod segment 2422. The bracket 24 also includes an adjusting member 245 and a rotating shaft 246. The second rod segment 2422 can swing relative to the first rod segment 2421 about the rotating shaft 246. The axis of the rotating shaft 246 is parallel to the cross-section of the sliding rod 232. The adjusting member 245 is used to adjust the swing of the second rod segment 2422.

[0249] In some examples, along the length of the second connecting rod 242, the first rod segment 2421 and the second rod segment 2422 are arranged sequentially, and the rotating shaft 246 is arranged between the first rod segment 2421 and the second rod segment 2422.

[0250] In some examples, the adjusting element 245 may include an adjusting motor connected to the first lever segment 2421. The output shaft of the adjusting motor is rotatably connected to the rotating shaft 246 to drive the rotating shaft 246 to rotate, thereby driving the second lever segment 2422 to rotate, thus adjusting the oscillation (pitch angle) of the second lever segment 2422. This adjusts the contact degree between the probe 221 of the ranging component 22 and the first end of the sliding rod 232, achieving fine-tuning of the ranging component 22. Of course, the structure of the adjusting element 245 can also be of other types.

[0251] With the above configuration, the second connecting rod 242 is divided into two parts: a first rod segment 2421 and a second rod segment 2422. The second rod segment 2422 is swung relative to the first rod segment 2421 by the adjusting member 245, thereby adjusting the pitch angle of the second rod segment 2422. This adjusts the displacement of the ranging component 22 in the sliding direction of the sliding rod 232, adjusts the contact degree between the probe 221 and the first end of the sliding rod 232, and adjusts the initial display value of the meter body 222, thus achieving fine-tuning of the position of the ranging component 22.

[0252] For example, if the sliding direction (Z direction) of the sliding rod 232 is vertical, and the adjusting member 245 adjusts the second rod segment 2422 to swing downward relative to the first rod segment 2421, then the second rod segment 2422 will drive the ranging component 22 to move downward, thereby increasing the contact degree between the probe 221 and the first end of the sliding rod 232, thus increasing the initial value of the ranging component 22. Conversely, if the adjusting member 245 adjusts the second rod segment 2422 to swing upward relative to the first rod segment 2421, then the second rod segment 2422 will drive the ranging component 22 to move upward, thereby decreasing the contact degree between the probe 221 of the ranging component 22 and the first end of the sliding rod 232, thus decreasing the initial value of the ranging component 22, thereby achieving fine-tuning of the initial value of the ranging component 22.

[0253] Another structure for the adjusting member 245 is provided below, in some embodiments, such as Figure 14 As shown, the ends of the first rod segment 2421 and the second rod segment 2422 that are close to each other are respectively connected to a mounting plate 2451 and abutment plate 2452. The mounting plate 2451 and abutment plate 2452 are arranged along the swing direction, and the abutment plate 2452 can swing relative to the mounting plate 2451 around the rotation axis 246. The adjusting member 245 includes a pressing part 2453 and a spring-loaded part 2454. Along the swing direction, the pressing part 2453 and the spring-loaded part 2454 abut against the opposite sides of the abutment plate 2452. The pressing part 2453 can push forward or retract and cooperate with the spring-loaded part 2454 to adjust the swing of the abutment plate 2452.

[0254] It is understandable that the swing of the abutment plate 2452 relative to the mounting plate 2451 is to achieve the swing of the second rod segment 2422 relative to the first rod segment 2421.

[0255] In some examples, a small gap may be provided between the mounting plate 2451 and the abutment plate 2452 to facilitate the swinging of the abutment plate 2452 relative to the mounting plate 2451, thus facilitating the rotation of the abutment plate 2452.

[0256] In some examples, the mounting plate 2451 and the abutment plate 2452 are arranged sequentially along the arrangement direction of the first pole segment 2421 and the second pole segment 2422, so that the mounting plate 2451 is arranged near the first pole segment 2421 and the abutment plate 2452 is arranged near the second pole segment 2422, which facilitates connection.

[0257] Based on this, in some examples, the clamping part 2453 can be a bolt or screw. A threaded hole is provided on the mounting plate 2451, through which the clamping part 2453 passes and is threadedly connected. By rotating the clamping part 2453, it pushes forward, applying a thrust to the abutment plate 2452. After the abutment plate 2452 is subjected to this force, it rotates slightly around the rotation axis 246. Simultaneously, the abutment plate 2452 causes the second rod segment 2422 to swing downwards, thereby causing the ranging assembly 22 to swing downwards, increasing the contact between the probe 221 and the first end of the sliding rod 232, and increasing the initial value of the ranging assembly 22. When the tightening part 2453 rotates back, the abutment plate 2452 can swing back to its original position under the action of the spring-back part 2454. At the same time, the setting of the spring-back part 2454 also ensures that the abutment plate 2452 is always in contact with the tightening part 2453.

[0258] The length direction of the bolts or screws can be consistent with the arrangement direction of the mounting plate 2451 and the abutment plate 2452. Alternatively, they can be at an angle to the arrangement direction of the mounting plate 2451 and the abutment plate 2452.

[0259] In other examples, the clamping part 2453 may also include a telescopic motor or a telescopic cylinder. The clamping part 2453 is connected to the first rod segment 2421, and the output shaft of the clamping part 2453 abuts against the abutment plate 2452.

[0260] In some examples, the rotation shaft 246 is located in the middle of both the abutment plate 2452 and the mounting plate 2451, in a direction perpendicular to the arrangement of the mounting plate 2451 and the axis of the rotation shaft 246. Thus, the upper and lower sides of the rotation shaft 246 each have portions of the mounting plate 2451 and the abutment plate 2452, and the lower portions of the mounting plate 2451 and the abutment plate 2452 can also constrain each other, preventing excessive swinging of the abutment plate 2452.

[0261] With the above configuration, in the swing direction, the clamping part 2453 can be pushed in to drive the abutment plate 2452 to swing, thereby driving the second rod 2422 connected to the abutment plate 2452 to swing, thus adjusting the displacement of the ranging component 22, changing the contact degree between the probe 221 and the first end of the sliding rod 232, and adjusting the initial value of the meter body 222. Alternatively, by retracting the clamping part 2453, the spring-loaded part 2454 can drive the abutment plate 2452 to swing back, thereby adjusting the displacement of the ranging component 22, reducing the contact degree between the probe 221 and the first end of the sliding rod 232, and adjusting the initial value of the meter body 222. The swing adjustment is achieved through the cooperation of the clamping part 2453 and the spring-loaded part 2454, while also ensuring the stability of the fixture when no adjustment is being made.

[0262] The following describes the configuration of the springback section 2454. In some embodiments, such as... Figure 15 As shown, the springback part 2454 includes an elastic clamping plate 24541, and the two ends of the elastic clamping plate 24541 abut against the opposite sides of the mounting plate 2451 and the abutment plate 2452, respectively.

[0263] A through hole h is provided in the elastic clamping plate 24541, through which the tightening part 2453 can pass and abut against the abutting plate 2452. The presence of the through hole h can limit the tightening part 2453 and restrict its displacement.

[0264] In some examples, the elastic clamping plate 24541 can be an arc-shaped plate, with its opposite ends abutting against the opposing sides of the mounting plate 2451 and the abutting plate 2452 along the bending direction of the arc-shaped plate.

[0265] Alternatively, the elastic clamping plate 24541 may also include multiple plate segments connected in sequence, the multiple plate segments being arranged around the rotation axis 246, and in the arrangement direction of the multiple plate segments, the plate segments located at the two ends abut against the opposite sides of the mounting plate 2451 and the abutment plate 2452.

[0266] By abutting against the opposite sides of the mounting plate 2451 and the abutment plate 2452, the elastic clamping plate 24541 can be easily set up, thus ensuring the realization of the springback function of the elastic clamping plate 24241.

[0267] Of course, in other embodiments, the spring-back portion 2454 can also be an elastic column or spring, etc. The spring-back portion 2454 can be disposed between the mounting plate 2451 and the abutment plate 2452. Correspondingly, the clamping portion 2453 abuts against the side of the abutment plate 2452 away from the mounting plate 2451. The spring-back portion 2454 and the clamping portion 2453 are configured to satisfy the following: during the pushing process of the clamping portion 2453, the abutment plate 2452 swings, and at the same time, the spring-back portion 2454 undergoes elastic deformation. During the retraction process of the clamping portion 2453, the elastic force of the spring-back portion 2454 can drive the abutment plate 2452 to swing back.

[0268] In some embodiments, such as Figure 15 As shown, the mounting plate 2451 and the abutment plate 2452 have positioning grooves D on opposite sides, and the two ends of the elastic clamping plate 24541 extend into the positioning grooves D on the corresponding sides.

[0269] In some examples, the shape of the positioning groove D is adapted to the end shape of the elastic clamping plate 24541, which ensures the stability of the arrangement between the elastic clamping plate 24541 and the positioning groove D.

[0270] For example, the end of the elastic clamping plate 24541 is a cuboid structure, and the positioning groove D is a cuboid structure. Alternatively, the end of the elastic clamping plate 24541 is a cylindrical structure, and the positioning groove D is a cylindrical structure.

[0271] By setting the positioning groove D, the elastic clamping plate 24541 can stably abut against the mounting plate 2451 and the abutment plate 2452, which facilitates the installation and setting of the mounting plate 2451 and the abutment plate 2452, while ensuring the stability of the abutment between the elastic clamping plate 24541 and the mounting plate 2451 and the abutment plate 2452.

[0272] In some embodiments, such as Figure 4 As shown, the bracket 24 is connected to the first adsorption element 247, and the bearing assembly 21 is connected to the second adsorption element. The first adsorption element 247 and the second adsorption element 211 are magnetically attracted to each other.

[0273] The first adsorption element 247 includes a magnet, and the second adsorption element 211 includes an iron product. Alternatively, the first adsorption element 247 includes an iron product, and the second adsorption element 211 includes a magnet. Alternatively, both the first adsorption element 247 and the second adsorption element 211 include magnets.

[0274] For example, the magnet may include a permanent magnet or an electromagnet.

[0275] For example, iron products may include iron plates or iron blocks, etc.

[0276] In some examples, where the bracket 24 includes a first connecting rod 241 and a second connecting rod 242, the first adsorption member 247 can be connected to the bottom of the first connecting rod 241, so that the arrangement of the first adsorption member 247 does not affect the positional adjustability of the ranging component 22.

[0277] In some examples, such as Figure 4 As shown, the second adsorption member 211 is connected to the top surface of the support component 21, and the first adsorption member 247 is adsorbed on the side of the second adsorption member 211 away from the support component 21.

[0278] For example, an installation groove is provided on the top surface of the support component 21, and the second adsorption member 211 is disposed in the installation groove, which facilitates the installation and positioning of the second adsorption member 211 and the support component 21.

[0279] For example, the first adsorption member 247 includes a magnet, and the second adsorption member 211 includes an iron plate connected to the top surface of the support assembly 21. The first adsorption member 247 is disposed on the side of the iron plate away from the top surface of the support assembly 21 and adsorbs onto the iron plate.

[0280] The iron plate can be a single, solid piece.

[0281] Alternatively, the iron plate may comprise multiple sub-plates, each connected to the supporting component 21. In this case, there may be one mounting slot, accommodating multiple sub-plates. Alternatively, there may be multiple mounting slots spaced apart, each containing a sub-plate.

[0282] In some examples, the first adsorption element 247 includes a magnet, and a magnetic control dial can be connected to the bracket 24. By adjusting the magnetic control dial, for example by turning a button, the first adsorption element 247 can be made magnetic or demagnetized, thereby causing the first adsorption element 247 to be attracted to or separated from the second adsorption element 211. This facilitates the connection and separation of the bracket 24 and the support assembly 21, making it convenient for practical operation.

[0283] By connecting the first adsorption member 247 to the bracket 24 and the second adsorption member 211 to the support assembly 21, the bracket 24 is stably fixed to the support assembly 21 through the magnetic attraction between the first adsorption member 247 and the second adsorption member 211. This, in turn, stably fixes the ranging component 22 to the support assembly 21, ensuring accurate distance measurement by the ranging component 22. When it is necessary to remove the ranging component 22 from the support assembly 21, for example, when the ranging component 22 malfunctions and needs to be replaced, simply disengage the magnetism between the first adsorption member 247 and the second adsorption member 211, and the bracket 24 can be removed from the support assembly 21, thereby removing the ranging component 22 from the support assembly 21. The first adsorption member 247 and the second adsorption member 211 facilitate the connection and disassembly of the bracket 24 and the support assembly 21, and also facilitate the connection and disassembly of the ranging component 22 from the support assembly 21.
