Description

Technical Field

[0001] The utility model relates to the technical field of linear motors, in particular to a thin linear motor slide module. Background Art

[0002] Linear motor, also known as linear motor, is a motor that can produce linear motion. It can convert electrical energy into mechanical energy for linear motion. The electromechanical principle is used in linear and rotary motors. The same electromagnetic force produces torque on the rotary motor and linear thrust on the linear motor, so that the thrust drives the specified object to move.

[0003] The existing Chinese patent with reference announcement number CN212935749U discloses a thin flat linear motor with an explosion-proof structure, including a support base and a fixed support, the front end top and bottom sides of the support base are fixed with positioning fences, and the front end middle of the support base is provided with a magnetic plate, the front end of the magnetic plate is provided with a magnet, and the front end of the magnet is movably connected with a motor coil, the front end bottom of the motor coil is fixed with a positioning iron block, and the front end top of the motor coil is provided with a rotating shaft, the other end of the rotating shaft is connected with a heat sink, and the front end middle of the heat sink is provided with a thermal pad, and the top middle of the heat sink is provided with an iron magnet. The thin flat linear motor with an explosion-proof structure is put into the coolant with the volume of a water storage dish, so that the heat in the magnetic plate and the support base can be offset under the action of the coolant, thereby avoiding the heat accumulated in the magnetic plate from being dissipated around the flat linear motor, affecting the service life of the entire device.

[0004] The existing Chinese patent with reference announcement number CN212935750U discloses a thin flat linear motor with a protective structure for heat dissipation, including a protective shell, an isolation fixed block and a first heat dissipation plate, the four corners of the protective shell are fixed with mounting blocks, and the middle of the protective shell is provided with a limited inner frame, the upper left and right ends of the protective shell are provided with limited slide grooves, and limited slide plates are distributed between the limited slide grooves, the middle of the limited slide plate is provided with a second heat dissipation plate, and the four corners of the second heat dissipation plate are fixed with fixed buttons, and the middle of the second heat dissipation plate is distributed with heat dissipation mesh holes. The thin flat linear motor with a protective structure for heat dissipation is provided with a protective shell, and the protective shell can protect the internal flat linear motor body, which can effectively prevent the flat linear motor body from being damaged by collision, and the first heat dissipation plate and the second heat dissipation plate can dissipate heat from top to bottom of the device, greatly improving the service life of the device.

[0005] Although the above patents have the effects of a light and thin structure and a heat dissipation structure, and both use magnetic force as the driving force, they do not have relevant structures to assist in increasing the precision of magnetic motion. Under the drive of magnetic force, since both sides of the above patents use traditional guide rail structures, under the action of continuous friction of reciprocating motion, the probability of guide rail wear increases. When the degree of wear of the guide rail reaches a critical value, it may directly affect the motion precision of the linear motor, thereby directly causing the product to be scrapped. In addition, since its guide rail structure requires a corresponding guide structure, a certain amount of internal space needs to be reserved for the installation of its guide structure, and this structure increases the overall internal space of the motor. The floating height of the motor as a whole is increased by 3-10cm. For specified installation environments and relatively narrow installation environments, the structure needs to be further improved, such as cutting the plane of the base to ensure that the guide rail avoids motion errors and reduces the influence of the motor height. This increases the process and reduces work efficiency, and also increases the risk of deformation or damage caused by the base being too weak. For this reason, the inventors propose a thin linear motor slide module to solve the technical problems of improving the traditional guide rail structure to increase the motion accuracy of the motor and compress the overall floating height of the motor so that the motor can be suitable for narrow installation environments.

DETAILED DESCRIPTION

[0040] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] For this example, please refer to Figure 1-Figure 17 , a thin linear motor slide module specifically implemented, including a mover seat 1, a base 2, a stator structure 3 and a drive motor 4, the mover seat 1 and the base 2 are detachable structures, the mover seat 1 and the base 2 are directly provided with an air avoidance groove 5, the air avoidance groove 5 is symmetrically arranged, a steel rail 6 is installed inside the air avoidance groove 5, the steel rail 6 is symmetrically arranged, a sliding structure is connected between two adjacent steel rails 6, the sliding structure includes a roller fixing plate 7, a first adjusting roller 8 and a second adjusting roller 9, the first adjusting roller 8 and the second adjusting roller 9 are installed in the roller fixing plate 7 in opposite directions, a slide groove 10 used in pair with the first adjusting roller 8 and the second adjusting roller 9 is opened in the middle of the steel rail 6, and the slide groove 10 is consistent in shape with the first adjusting roller 8 and the second adjusting roller 9;

[0042] The first adjusting roller 8 and the second adjusting roller 9 are installed in opposite directions inside the roller fixing plate 7, so that the first adjusting roller 8 and the second adjusting roller 9 are evenly stressed at both ends, avoiding the probability of deformation of the first adjusting roller 8 or the second adjusting roller 9 due to excessive local force. In addition, the installation structure in opposite directions plays a role of bidirectional distribution. When the rail 6 moves, the first adjusting roller 8 and the second adjusting roller 9 can slide along the inside of the slide groove 10, thereby increasing the stability of the equipment operation and the stability of the motion accuracy; improving the point contact motion mode of the traditional steel ball;

[0043] While achieving the point contact motion accuracy, it has the stability of the line contact motion mode, reduces the situation where the first adjusting roller 8 or the second adjusting roller 9 is locally deformed due to stress imbalance, adopts the point movement mode of the first adjusting roller 8 and the second adjusting roller 9, improves the traditional guide rail using the surface movement mode, and improves the motion accuracy of the guide rail and reduces the traditional height of the guide rail through this structure, while reducing the overall height, further increasing the motion accuracy;

[0044] The stator structure 3 is located inside the mover seat 1, and a mounting groove 11 for mounting the stator structure 3 is provided inside the mover seat 1, and the highest point of the stator structure 3 is flush with one end of the surface of the mover seat 1, and one end of the drive motor 4 is connected to a mover structure 12 used in pair with the stator structure 3, and a placement groove 13 for placing the drive motor 4 is provided inside the base 2, and one end of the drive motor 4 is in contact with the surface of the placement groove 13, and the highest point of the mover structure 12 is flush with one end of the surface of the base 2;

[0045] The stator structure 3, the drive motor 4 and the mover structure 12 are all embedded or inserted in a structural manner, so as to compress the overall space and reduce the overall height of the equipment, so as to meet the requirements of narrow space use within a combined height of 30 mm. The embedded or inserted structural manner of the drive motor 4 can compress the structural space without affecting the installation and replacement of the drive motor 4 and ensuring the rigidity of the base 2, thereby further reducing the overall height of the equipment.

[0046] The mover seat 1 and the stator structure 3 are detachable structures, the mounting grooves 11 are linearly arranged on the surface of the mover seat 1, the number of the stator structure 3 and the mounting grooves 11 are the same, and they are coaxially arranged structures;

[0047] Since the mover seat 1 and the stator structure 3 are detachable, when the equipment fails or needs maintenance, the relevant parts can be easily disassembled and replaced, which greatly improves the maintainability of the equipment. Different types of stator structures can be replaced according to actual needs to adapt to different application scenarios or work requirements, which enhances the flexibility of the equipment, helps to reduce installation and disassembly time, and improves production efficiency.

[0048] The number of the stator structure 3 and the mounting groove 11 are consistent and they are coaxially arranged, which helps to ensure accurate alignment and tight fit between the mover seat 1 and the stator structure 3, thereby improving the structural stability and working reliability of the entire device. The linear arrangement makes it easy for the stator structure 3 and the mover structure 12 to generate a magnetic driving force, so that the force can be transmitted along the direction of the linear arrangement, thereby increasing the instantaneous thrust of the device during operation.

[0049] The surface of the mover seat 1 is provided with a plurality of connection holes 14 for connecting to the surface of the rail 6, and the surface of the rail 6 is provided with matching holes 15 which are matched with the connection holes 14. The connection holes 14 and the matching holes 15 have the same diameter and shape and are coaxially arranged.

[0050] Since the diameter and shape of the connecting hole 14 and the matching hole 15 are consistent, the two can be accurately matched and connected. This accuracy is crucial to ensure the relative position relationship between the mover seat 1 and the rail 6, and can ensure the stability and reliability between the two. At the same time, the design of the connecting hole 14 and the matching hole 15 being a coaxial arrangement structure simplifies the assembly process and improves work efficiency. If parts need to be replaced or repaired, this structure also makes the disassembly method convenient and quick;

[0051] When the connecting hole 14 and the matching hole 15 are connected by external screws, the two are tightly matched, making the connection between the mover seat 1 and the rail 6 more secure. This structure enhances the overall structural strength and improves its bearing capacity, enabling it to better withstand external loads and vibrations. When the rail 6 moves, it can also drive the mover seat 1 to move synchronously, thereby improving the stability of the movement, which is crucial to ensuring the normal operation of the entire system.

[0052] The surface of the base 2 is provided with a plurality of wire outlets 16, one end of which is connected to the interior of the placement slot 13; the design of the wire outlet 16 enables wires, cables or other connection lines to be orderly led out from the interior of the placement slot 13 to the outside of the base 2, which helps to manage the cables and avoid confusion, entanglement or damage to the cables. Since the wire outlet 16 is connected to the interior of the placement slot 13, the cables will not be subjected to excessive pressure or friction when passing through the wire outlet, thereby reducing the risk of cable damage;

[0053] In addition, during installation or maintenance work, workers can easily introduce or lead out cables through the cable outlet 16 without complicated disassembly or reassembly of the equipment or base 2. The cables can be introduced into the placement groove 13 through the cable outlet 16 to reduce the portion of the cable exposed to the external environment, thereby reducing the risk of external interference or damage to the cable, and improving the reliability and stability of the equipment. The design of fixed buried cable outlet can avoid the risk of leakage caused by damage to the cable during movement.

[0054] A pad 17 is connected to one end of the mover seat 1, and a limiting groove 18 is provided between the pad 17 and the mover seat 1, a reading head 19 is installed inside the limiting groove 18, one end of the reading head 19 is a power connection line 20, a protective plate 25 is connected to the surface of the reading head 19, and one end of the limiting groove 18 is an open structure. The mover seat 1 and the pad 17 are independent structures, and the reading head 19 plays a measuring role. When the mover seat 1 moves, since the reading head 19 is installed inside the limiting groove 18, it does not move with the mover seat 1, thereby ensuring the directional measurement accuracy of the reading head 19, so as to assist the operator to adjust the power of the drive motor 4 according to the measurement value of the reading head 19, and the pad 17 and the protective plate 25 both play a role in protecting the reading head 19.

[0055] The surfaces of the first adjusting roller 8 and the second adjusting roller 9 are both provided with chamfers, and the surface of the roller fixing plate 7 is provided with positioning grooves 21 for installing the first adjusting roller 8 and the second adjusting roller 9. The roller fixing plate 7 is located between two adjacent rails 6, and the surfaces at both ends are respectively in contact with the surfaces of the two adjacent rails 6, and the size of the roller fixing plate 7 is smaller than the size of the rail 6;

[0056] Since the size of the roller fixing plate 7 is smaller than the rail 6, it can adapt to rails of different sizes, thereby improving the versatility and flexibility of the device. The roller fixing plate 7, which is smaller than the rail 6, is easier to install and position between the rails 6. At the same time, due to its small size, the space required for installation is also reduced accordingly, making the installation process easier. In addition, the contact area between two adjacent rails 6 is reduced by the roller fixing plate 7, thereby reducing friction and wear, which helps to extend the service life and reduce the frequency of maintenance and replacement.

[0057] The surfaces of the first adjusting roller 8 and the second adjusting roller 9 are both provided with a chamfer structure, so that when the first adjusting roller 8 and the second adjusting roller 9 slide inside the slide groove 10, the chamfer plays a role of guiding and reducing the surface wear of the first adjusting roller 8 and the second adjusting roller 9. The angle of the chamfer is 45°. Since the angle of the chamfer is consistent with the internal angle of the slide groove 10, the first adjusting roller 8 and the second adjusting roller 9 play a more stable role when sliding, which plays a role of improving the movement accuracy and stability. Another function of the chamfer is to make the first adjusting roller 8 and the second adjusting roller 9 more consistent with the internal shape of the slide groove 10, thereby reducing the reaction force generated by the first adjusting roller 8 and the second adjusting roller 9 when moving;

[0058] Since the guide angles of the first adjusting roller 8 and the second adjusting roller 9 fit with the inside of the slide groove 10, the stress during their movement is dispersed to the first adjusting roller 8 and the second adjusting roller 9 as a whole, achieving the point contact movement accuracy while having the stability of the line contact movement method, reducing the stress imbalance that causes local deformation of the first adjusting roller 8 or the second adjusting roller 9, and adopting the point movement method of the first adjusting roller 8 and the second adjusting roller 9 to improve the traditional guide rail using the surface movement method. Through this structure, the movement accuracy of the guide rail is improved and the traditional height of the guide rail is reduced. While reducing the overall height, the movement accuracy is further increased.

[0059] The base 2 is provided with a travel movable groove 22 inside which a plurality of anti-collision rubber blocks 23 are provided, and the highest point of the anti-collision rubber block 23 is flush with the surface of one end of the base 2; when the mover seat 1 moves in the travel movable groove 22 and comes into contact with the anti-collision rubber block 23, the elasticity and energy absorption performance of the anti-collision rubber block 23 can effectively absorb and disperse the impact force, reduce the vibration and impact of the mover seat 1, play a buffering role, reduce the risk of damage to the mover seat 1, and thus protect it from damage; in addition, since the anti-collision rubber block 23 has a certain elasticity, the mover seat 1 provides a certain resistance when moving, making its operation more stable and reducing the noise and vibration caused by the impact;

[0060] The highest point of the anti-collision rubber block 23 is flush with the surface of the base 2, so that the mover seat 1 can contact the anti-collision rubber block 23 more smoothly when moving to the end of the travel movable groove 22, thereby better playing its buffering and shock absorbing role. The flush design can reduce the risk of the mover seat 1 getting stuck or colliding with the base 2 during movement, thereby improving safety in use.

[0061] The drive motor 4 is composed of a linear motor; the linear motor system has high-precision characteristics, and its direct drive structure eliminates the backlash and has high structural rigidity. The feedback repetition accuracy of the drive motor 4 is within 1um. In addition, the stator structure 3 and the mover structure 12 paired with the drive motor 4 adopt a magnetic driving method, and there is no mechanical contact and wear between the two. Therefore, the system runs smoothly, has low noise, and has a simple structure, simple maintenance or even maintenance-free, thereby improving reliability and extending service life. The drive motor 4 is used to drive the electric transmission kinetic energy that directly converts electrical energy into linear motion mechanical energy;

[0062] When the drive motor 4 is energized, the stator structure 3 and the mover structure 12 at one end of the drive motor 4 generate a traveling wave magnetic field, and a driving force is generated under the action of the traveling wave magnetic field and the secondary permanent magnet (motor structure 12), thereby realizing the linear motion of the moving parts. At the same time, an alternating magnetic field is generated between the magnetic field and the rail 6. The magnetic force drives the rail 6 to move back and forth instead of the traditional linear motor mover structure 12, thereby driving the mover seat 1 to move. The rated thrust is within 8N and the instantaneous thrust is within 24N.

[0063] The base 2 and the drive motor 4 are detachable structures; the base 2 and the drive motor 4 are detachable structures so that they can be stored separately when not in use, which can greatly reduce the overall volume, making it easier to transport and store, and is suitable for environments with limited space or scenes where the equipment needs to be moved frequently. This arrangement is convenient for maintenance and replacement. If any part of the base 2 or the drive motor 4 fails or needs maintenance, the detachable structure allows the user to easily separate them, so that they can be repaired or replaced more easily, which not only saves time but also reduces maintenance costs;

[0064] On the other hand, in a specified application environment, if motors of different specifications or types are needed to meet different needs, the detachable structure allows users to easily replace the motor to adapt to different work scenarios or task requirements. At the same time, if any part of the base 2 or the drive motor 4 is damaged, through the detachable design, the user only needs to replace the damaged part, reducing the need to replace the entire equipment, thereby reducing the overall cost.

[0065] One end of the steel rail 6 is in contact with the inner wall of the mover seat 1 through the fixing plate 24. When the steel rail 6 replaces the traditional linear motor mover structure 12 to perform reciprocating motion, thereby driving the mover seat 1 to move, since one of the two steel rails 6 is connected to the inner wall of the mover seat 1 through the fixing plate 24, the other steel rail 6 is limited to the surface of the base 2. When the mover seat 1 drives the fixing plate 24 and the steel rail 6 to move, the first adjusting roller 8 and the second adjusting roller 9 assist the steel rail 6 in driving the mover seat 1 to move along the slide groove 10;

[0066] The guide rail adopts a point movement method of the first adjusting roller 8 and the second adjusting roller 9, which improves the traditional guide rail's surface movement method. This structure improves the movement accuracy of the guide rail and reduces the traditional height of the guide rail. In addition, the stator structure 3, the drive motor 4 and the mover structure 12 are all embedded or inserted in a structural manner, so that the overall matching height of the mover seat 1 and the base 2 is within 30 mm.

[0067] The key points of the design of the utility model are: the first adjusting roller 8 and the second adjusting roller 9 are installed in the opposite directions inside the roller fixing plate 7, so that the first adjusting roller 8 and the second adjusting roller 9 are evenly stressed at both ends, avoiding the probability of deformation of the first adjusting roller 8 or the second adjusting roller 9 due to excessive local force. In addition, the installation structure in opposite directions plays a role of bidirectional distribution. When the rail 6 moves, the first adjusting roller 8 and the second adjusting roller 9 can slide along the inside of the slide groove 10, thereby increasing the stability of the operation of the equipment and the stability of the motion accuracy; improving the point contact motion mode of the traditional steel ball;

[0068] While achieving the point contact motion accuracy, it has the stability of the line contact movement mode, reduces the stress imbalance that causes local deformation of the first adjusting roller 8 or the second adjusting roller 9, adopts the point movement mode of the first adjusting roller 8 and the second adjusting roller 9, improves the traditional guide rail using the surface movement mode, and through this structure, improves the motion accuracy of the guide rail and reduces the traditional height of the guide rail, while reducing the overall height, further increases the motion accuracy.

[0069] On the other hand, Fig.15 As shown, the stator structure 3 and the mover structure 12 are within the frame line. The stator structure 3, the drive motor 4 and the mover structure 12 are all embedded or inserted in a structure mode, so as to achieve the effect of compressing the overall space and reducing the overall height of the equipment, so as to meet the requirements of narrow space use within a combined height of 30 mm. Fig.16 As shown, the frame line contains the drive motor 4. The embedded or inserted structure of the drive motor 4 can compress the structural space without affecting the installation and replacement of the drive motor 4 and ensuring the rigidity of the base 2, thereby further reducing the overall height of the equipment.

[0070] The action process of the utility model is as follows: when the drive motor 4 is energized, the stator structure 3 and the mover structure 12 at one end of the drive motor 4 generate a traveling wave magnetic field, and a driving force is generated under the action of the traveling wave magnetic field and the secondary permanent magnet (motor structure 12), thereby realizing the linear motion of the moving parts. At the same time, an alternating magnetic field is generated between the magnetic field and the rail 6, and the rail 6 is pushed by magnetic force to make the traditional linear motor move back and forth, thereby driving the mover seat 1 to move. Its rated thrust is 8N and the instantaneous thrust is 24N.

[0071] like Fig.17 As shown, the frame line contains the rail 6, and the movement of the mover seat 1 drives one of the two rails 6 to move, and when the rail 6 moves, it drives the first adjusting roller 8 and the second adjusting roller 9 to slide. Since the first adjusting roller 8 and the second adjusting roller 9 are installed in opposite directions, they play a bidirectional distribution role. The first adjusting roller 8 and the second adjusting roller 9 both slide along the inside of the slide groove 10, achieving the point contact motion accuracy while having the stability of the line contact motion mode, reducing the stress imbalance that causes local deformation of the first adjusting roller 8 or the second adjusting roller 9, thereby maintaining the stability of the equipment operation and the stability of the motion accuracy.

[0072] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as the protection scope of the present invention.
