Description

Technical Field

[0001] This application relates to the technical field of electronic component mounting, and particularly to a Z-axis drive mechanism applied to a mounter. Background Art

[0002] With the continuous progress of technology, electronic components such as chips are becoming increasingly miniaturized and surface-mounted, making it difficult to perform manual operations during the production of specific electronic products. Therefore, the mounter, as a device that can quickly and accurately mount electronic components to the designated positions on the circuit board, plays a crucial role in production. However, the mounter, especially the high-end mounter, is relatively expensive, which limits its widespread use to a certain extent. In the operation of the mounter, the Z-axis linear motor, as a component that controls the movement of the robotic arm in the vertical direction, is crucial for achieving precise grasping and rapid installation of components.

[0003] In traditional mounters, a single Z-axis linear motor needs to repeat the operations of grasping and installing when mounting a large number of identical parts. This not only causes the robotic arm to move frequently but also leads to low assembly efficiency. Although there are some improvement measures in the prior art, such as optimizing the movement trajectory of the robotic arm or improving the response speed of the Z-axis linear motor, the problems caused by frequent movement have not been fundamentally solved, and it is difficult to improve production efficiency. Summary of the Utility Model

[0004] In order to improve the assembly efficiency of the mounter when mounting a large number of identical parts, this application provides a Z-axis drive mechanism applied to a mounter.

[0005] The Z-axis drive mechanism applied to a mounter provided by this application adopts the following technical solutions:

[0006] A Z-axis drive mechanism applied to a mounter includes N Z-axis linear motors arranged in parallel, where N is an integer greater than or equal to 1; each Z-axis linear motor includes a housing, a plurality of connecting parts spaced apart on the housing, and connecting through-holes provided on the connecting parts. The connecting parts between two adjacent Z-axis linear motors are mutually abutted by a positioning component so that the two connecting through-holes are mutually communicated, and the adjacent two Z-axis linear motors are fixedly connected by fastening members passing through the adjacent two connecting through-holes.

[0007] By adopting the above technical solution, multiple Z-axis linear motors are arranged in parallel, allowing the mounter to operate multiple placement heads simultaneously. This enables the processing of multiple components within a single working cycle, significantly improving the production capacity and efficiency of the mounter. On the housing of each Z-axis linear motor, there are connection parts and connection through-holes. These connection through-holes are tightly pressed against each other through the positioning components, ensuring a very tight and stable connection between adjacent motors, effectively reducing mechanical loosening problems during the assembly process, and improving the reliability and precision of the system. Through fasteners passing through adjacent connection through-holes, adjacent Z-axis linear motors are fixedly connected, which ensures that the system will not experience unexpected movement or deformation during operation, maintaining high-precision motion control and the stability of the placement operation. This design enables the mounter to be installed and adjusted more quickly, which is particularly effective in a large-scale production environment. At the same time, it also provides flexibility and scalability because the number of parallel Z-axis linear motors can be increased or decreased according to requirements to adapt to different production requirements and part types, improving the assembly efficiency of the mounter when installing a large number of identical parts, and at the same time enhancing the overall performance and reliability of the production line.

[0008] Optionally, the positioning component includes a positioning hole provided on the connection part, a positioning post with one end located in the positioning hole and the other end passing through the positioning hole, and an accommodation space located in the positioning hole. The positioning post includes a fixed end and a positioning end. The fixed end is located in the positioning hole, and the positioning end passes through the positioning hole so that the positioning end can be embedded in the accommodation space of the adjacent Z-axis linear motor.

[0009] By adopting the above technical solution, the design of the positioning hole and the positioning post ensures precise alignment during the installation process. The positioning end of the positioning post passes through the positioning hole and is embedded in the accommodation space of the adjacent Z-axis linear motor, thus achieving precise alignment between the motors. This precise positioning is the basis for ensuring that the mounter can accurately position and move the placement head during operation; through the stable installation of the fixed end in the positioning hole, the positioning post can be firmly fixed on the connection part of the motor, ensuring that unnecessary movement or loosening will not occur during operation, and improving the stability and reliability of the entire mounter system; the use of the positioning hole and the positioning post simplifies the installation and adjustment process of multiple Z-axis linear motors. Workers can perform assembly more quickly because the positioning component ensures that each motor can be accurately installed in its designated position without the need for complex adjustment or repositioning.

[0010] Optionally, a magnetic separator is provided on the housing so that the magnetic separator is located between two Z-axis linear motors.

[0011] By adopting the above technical solution, in the case of multiple linear motors connected in parallel, since each motor generates a magnetic field, if these magnetic fields interfere with each other, it may affect the running stability of the motors and the overall performance of the system. To solve this problem, magnetic separators are installed on the housing. The magnetic separators can form a physical barrier between two motors to reduce the mutual influence of their magnetic fields, thereby effectively reducing the situation of unstable motor operation or increased error caused by the mutual interference of magnetic fields.

[0012] Optionally, the Z-axis linear motor includes a mover module and a stator module. The mover module includes a magnetic conduction strip fixed in the inner cavity of the housing and a plurality of magnets arranged at intervals on the magnetic conduction strip. The stator module includes a stator core fixed in the inner cavity of the housing and a stator coil wound around the stator core.

[0013] By adopting the above technical solution, through the design of the magnetic conduction strip and the stator core, the magnetic field energy can be effectively transmitted and converted, improving the efficiency and performance of the motor. By precisely designing and arranging the magnets, the magnetic conduction strip and the stator coil, the stable operation of the motor under various load conditions can be achieved, reducing vibration and noise. The design structure of this Z-axis linear motor utilizes the interaction of the magnetic conduction strip, the magnets, the stator core and the stator coil to achieve efficient, stable and precise motion control effects, and is suitable for industrial applications that require precise motion and high-efficiency energy conversion.

[0014] Optionally, the mover module further includes a fixed seat and a guide rail. The magnetic conduction strip is fixed on the guide rail. The fixed seat is fixedly connected to the housing. The fixed seat is provided with a sliding groove for the guide rail to slide, so that the guide rail reciprocates along the length direction of the housing.

[0015] By adopting the above technical solution, through the design of the guide rail and the sliding groove, the mover module can move smoothly along the length direction of the housing, ensuring the stability and reliability of the motor during operation; the design of the guide rail can help to position the magnetic conduction strip and the magnets accurately, thereby providing high-precision motion control, and is suitable for industrial applications that require precise position control; the structural design of the fixed seat and the guide rail makes the installation and maintenance of the motor more convenient, which can improve production efficiency and reduce maintenance costs; the design of the mover module including the fixed seat and the guide rail effectively supports and guides the movement of the magnetic conduction strip, thereby enhancing the operation efficiency and accuracy of the linear motor, and is suitable for various industrial application scenarios that require high-performance linear motion.

[0016] Optionally, a buffer pad is inlaid in the inner cavity of the housing to provide buffering for the mover module.

[0017] By adopting the above technical solution, the main function of the buffer pad is to absorb the impact and vibration generated during the movement of the mover module due to speed change or stop, which can effectively reduce the influence of these vibrations and impacts on the motor and the housing, and improve the stability and reliability of the equipment.

[0018] Optionally, a fixing groove for embedding the stator core is provided on the housing, a first fixing hole is provided at the bottom of the fixing groove, a second fixing hole communicating with the first fixing hole is provided on the stator core, and a locking screw, the locking screw passes through the second fixing hole and is threadedly connected to the first fixing hole.

[0019] By adopting the above technical solution, a fixing groove is provided inside the housing for embedding and fixing the stator core. This fixing groove is usually a space with a shape suitable for the stator core. A first fixing hole is opened at the bottom of the fixing groove (the bottom of the groove). The stator core itself has a second fixing hole communicating with the first fixing hole. In order to firmly fix the stator core on the housing, a locking screw is used. The locking screw passes through the second fixing hole on the stator core and, after entering the first fixing hole of the housing, is threadedly connected to the thread in the first fixing hole. This connection method ensures the stator core is firmly fixed on the housing through the fastening of the thread, preventing it from moving or loosening during operation and ensuring a stable connection between the stator core and the housing.

[0020] Optionally, the fastener includes a bolt and a nut. The bolt connects N of the Z-axis linear motors and is fixed by the nut.

[0021] Or, the fastener includes a screw. The screw passes through N of the connection through holes and is threadedly locked to N of the connection through holes.

[0022] By adopting the above technical solution, N Z-axis linear motors are connected together using a bolt and a nut. The nut is used to fasten on the other side of the bolt (the bottom of the motor or the mounting table) to ensure the motor is fixed in the correct position and remains stable; or, a screw is used. The thread of the screw will cooperate with the thread in the connection through hole, and thus be locked through threaded connection. This method does not require an additional nut because the screw itself provides the fastening force through its own thread. By either of these two technical solutions, multiple Z-axis linear motors can be effectively connected and fixed.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Multiple Z-axis linear motors are arranged in parallel, allowing the mounter to operate multiple placement heads simultaneously. This enables the processing of multiple components within a single working cycle, significantly enhancing the production capacity and efficiency of the mounter. On the housing of each Z-axis linear motor, there are connection parts and connection through-holes. These connection through-holes are tightly pressed against each other through positioning components, ensuring a very tight and stable connection between adjacent motors, effectively reducing mechanical looseness problems during the assembly process, improving the reliability and precision of the system. Adjacent Z-axis linear motors are fixedly connected through fasteners passing through adjacent connection through-holes, which ensures that the system will not experience unexpected movement or deformation during operation, maintaining high-precision motion control and the stability of the placement operation. This design enables the mounter to be installed and adjusted more quickly, which is particularly effective in large-scale production environments. It also provides flexibility and scalability as the number of parallel Z-axis linear motors can be increased or decreased according to requirements to adapt to different production requirements and part types, improving the assembly efficiency of the mounter when installing a large number of identical parts, and simultaneously enhancing the overall performance and reliability of the production line;

[0025] 2. The design of the positioning holes and positioning posts ensures precise alignment during installation. The positioning end of the positioning post passes through the positioning hole and is embedded in the accommodation space of the adjacent Z-axis linear motor, thus achieving precise alignment between the motors. This precise positioning is the basis for ensuring that the mounter can accurately position and move the placement head during operation; Through the stable installation of the fixed end in the positioning hole, the positioning post can be firmly fixed on the connection part of the motor, ensuring that there will be no unnecessary movement or looseness during operation, improving the stability and reliability of the entire mounter system; The use of positioning holes and positioning posts simplifies the installation and adjustment process of multiple Z-axis linear motors. Workers can perform assembly more quickly because the positioning components ensure that each motor can be accurately installed in its designated position without the need for complex adjustment or repositioning.

[0038] An embodiment of the present application discloses a Z-axis drive mechanism applied to a mounter.

[0039] Referring to Figure 1 and Figure 2 , a Z-axis drive mechanism applied to a mounter includes N Z-axis linear motors 1 arranged in parallel, where N is an integer greater than or equal to 1. The Z-axis linear motor 1 includes a housing 2, a connecting portion 3 and a connecting through hole 4. Each Z-axis linear motor 1 has a housing 2, which is its main mechanical protection and support structure. A number of connecting portions 3 are provided on the housing 2. These connecting portions 3 may be specifically designed protrusions or brackets for connecting other motors or external structures. Each connecting portion 3 has a connecting through hole 4. The connecting through hole 4 is usually designed to pass bolts, screws or other fasteners to connect adjacent motors; the connecting portions 3 of two adjacent Z-axis linear motors 1 are abutted against each other through a positioning component to ensure correct alignment and mutual locking of the connecting portions 3 during installation, so that two adjacent connecting through holes 4 communicate with each other. After the fasteners pass through the two adjacent connecting through holes 4, the two adjacent Z-axis linear motors 1 are fixedly connected.

[0040] In one embodiment, the fasteners can be bolts, screws or other types of mechanical fasteners. They pass through the adjacent connecting through holes 4 and fix the two motors together through threads or other locking mechanisms after passing through. For example, in Solution 1, the fasteners include bolts and nuts. The bolts connect the N Z-axis linear motors 1 and are fixed by nuts.

[0041] Use bolts and nuts to connect N Z-axis linear motors 1 together. The nuts are used to fasten on the other side of the bolts (the bottom of the motor or the mounting table) to ensure that the motors are fixed in the correct position and remain stable. Alternatively, use screws. The threads of the screws will mate with the threads in the connecting through-holes 4, so as to be locked by thread connection. This method does not require additional nuts because the screws themselves provide the fastening force through their own threads. Through any one of these two technical solutions, multiple Z-axis linear motors 1 can be effectively connected and fixed. Use bolts and nuts to connect N Z-axis linear motors 1 together. The nuts are used to fasten on the other side of the bolts (the bottom of the motor or the mounting table) to ensure that the motors are fixed in the correct position and remain stable. Solution two: The fastener includes screws. The screws pass through N connecting through-holes 4 and are thread-locked with the N connecting through-holes 4. Use screws. The threads of the screws will mate with the threads in the connecting through-holes 4, so as to be locked by thread connection. This method does not require additional nuts because the screws themselves provide the fastening force through their own threads. Through any one of these two technical solutions, multiple Z-axis linear motors 1 can be effectively connected and fixed.

[0042] Refer to Figure 3 , in the case of multiple linear motors connected in parallel, since each motor generates a magnetic field, if these magnetic fields interfere with each other, it may affect the running stability of the motors and the overall performance of the system. To solve this problem, magnetic separators 10 are installed on the housing 2. The magnetic separators 10 can form a physical barrier between two Z-axis linear motors 1 to reduce the mutual influence of their magnetic fields, which can effectively reduce the situation of unstable motor operation or increased error caused by the mutual interference of magnetic fields.

[0043] Refer to Figure 4 , the positioning component includes positioning holes 5, positioning posts 6 and accommodation spaces 7. The positioning posts 6 include fixed ends 8 and positioning ends 9. The positioning holes 5 are opened on the connecting part 3. It should be noted that the positioning holes 5 and the connecting through-holes 4 are not connected. One end of the positioning post 6 is located in the positioning hole 5, and the other end of the positioning post 6 passes through the positioning hole 5. The accommodation space 7 is located in the positioning hole 5. The fixed end 8 is located in the positioning hole 5, and the positioning end 9 passes through the positioning hole 5 so that the positioning end 9 can be embedded in the accommodation space 7 in the adjacent Z-axis linear motor 1. The design of the positioning holes 5 and the positioning posts 6 ensures precise alignment during the installation process. The positioning end 9 of the positioning post 6 passes through the positioning hole 5 and is embedded in the accommodation space 7 in the adjacent Z-axis linear motor 1, thus realizing the precise alignment between the motors. Through the stable installation of the fixed end 8 in the positioning hole 5, the positioning post 6 can be firmly fixed on the connecting part 3 of the motor, ensuring that unnecessary movement or loosening will not occur during operation, and improving the stability and reliability of the entire mounter system.

[0044] Refer to Figure 5 and Figure 6, the Z-axis linear motor 1 includes a mover module 11 and a stator module 12. The stator module 12 includes a magnetic conduction bar 13, a magnet 14, a fixed seat 17, and a guide rail 18, and the stator module 12 includes a stator core 15 and a stator coil 16. The magnetic conduction bar 13 is fixed in the inner cavity of the housing 2, and several magnets 14 are fixedly arranged on the magnetic conduction bar 13 at intervals. The magnetic conduction bar 13 is fixed on the book guide rail 18. The fixed seat 17 is fixedly connected to the housing 2, and the fixed seat 17 is provided with a sliding groove 19 for the guide rail 18 to slide, so that the guide rail 18 reciprocates along the length direction of the housing 2; the stator core 15 is fixed in the inner cavity of the housing 2, and the stator coil 16 is wound around the stator core 15. Through the design of the magnetic conduction bar 13 and the stator core 15, the magnetic field energy can be effectively transmitted and converted, improving the efficiency and performance of the motor. By precisely designing and arranging the magnet 14, the magnetic conduction bar 13, and the stator coil 16, the stable operation of the motor under various load conditions can be achieved, reducing vibration and noise. The designed structure of this Z-axis linear motor 1 utilizes the interaction of the magnetic conduction bar 13, the magnet 14, the stator core 15, and the stator coil 16 to achieve efficient, stable, and precise motion control effects, and is suitable for industrial applications that require precise motion and high-efficiency energy conversion.

[0045] The design of the mover module 11 including the fixed seat 17 and the guide rail 18 effectively supports and guides the movement of the magnetic conduction bar 13, thereby enhancing the operating efficiency and accuracy of the linear motor, and is suitable for various industrial application scenarios that require high-performance linear motion. However, since the movement of the magnetic conduction bar 13 is likely to cause impact on the motor, a buffer pad 20 is inlaid in the inner cavity of the housing 2 to provide buffering for the mover module 11. The main function of the buffer pad 20 is to absorb the impact and vibration generated during the speed change or stop when the mover module 11 moves, and can effectively reduce the influence of these vibrations and impacts on the motor and the housing 2, improving the stability and reliability of the equipment.

[0046] Furthermore, there is a fixed slot 21 inside the housing 2 of the housing 2 for the embedding and fixing of the stator core 15. This fixed slot 21 is usually a space with a shape suitable for the stator core 15. A first fixing hole 22 is opened at the bottom (slot bottom) of the fixed slot 21. The stator core 15 itself has a second fixing hole 23 communicating with the first fixing hole 22. In order to firmly fix the stator core 15 on the housing 2, a locking screw 24 is used. The locking screw 24 passes through the second fixing hole 23 on the stator core 15 and, after entering the first fixing hole 22 of the housing 2, is threadedly connected with the thread in the first fixing hole 22. This connection method ensures the firm fixing of the stator core 15 on the housing 2 through the tightening of the thread, preventing it from moving or loosening during operation, and ensuring a stable connection between the stator core 15 and the housing 2.

[0047] The implementation principle of a Z-axis drive mechanism applied to a mounter in an embodiment of this application is as follows: Multiple Z-axis linear motors 1 are arranged in parallel, allowing the mounter to operate multiple placement heads simultaneously. In this way, multiple components can be processed within a single working cycle, significantly improving the production capacity and efficiency of the mounter. On the housing 2 of each Z-axis linear motor 1, there are connection parts 3 and connection through-holes 4. These connection through-holes 4 are tightly pressed against each other through positioning components, ensuring a very tight and stable connection between adjacent motors, effectively reducing mechanical loosening problems during the assembly process, and improving the reliability and precision of the system. Adjacent Z-axis linear motors 1 are fixedly connected through fasteners passing through adjacent connection through-holes 4, which ensures that the system will not have unexpected movement or deformation during operation, maintaining high-precision motion control and the stability of the placement operation. This design enables the mounter to be installed and adjusted more quickly, which is particularly effective in a large-scale production environment. At the same time, it also provides flexibility and scalability because the number of parallel Z-axis linear motors 1 can be increased or decreased according to requirements to adapt to different production requirements and part types, improving the assembly efficiency of the mounter when installing a large number of identical parts, and at the same time enhancing the overall performance and reliability of the production line.

[0048] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
