[0037] The present utility model provides a linear module module 1000.

[0038] Please refer to Figures 2 to 7 , in an embodiment of the present utility model, the linear module module 1000 includes a plurality of linear modules 1, each linear module 1 drives a load correspondingly, and the plurality of linear modules 1 are arranged in an annular array structure along an axis.

[0039] The technical solution of the present utility model designs the linear module module 1000 to be formed by the circumferential array of a single linear module 1, and leaves a heat dissipation space between two adjacent linear modules 1, which can increase the air flow channels, ensure that the linear module 1 can fully dissipate heat during operation, avoid overheating, thereby extending the service life of the linear module 1 and improving the performance stability, enhancing the overall heat dissipation capacity and working performance of the module. Moreover, the width of the linear module 1 is not limited by the distance between adjacent loads, the module has sufficient space for design, high flexibility, and greater motor thrust. When one or more linear modules 1 in the middle are damaged, it is not necessary to remove the entire linear module 1 for replacement, and the maintainability is good.

[0040] It should be noted that, please refer to Figure 2 and Figure 3 , in the annular array structure, the axis is along the center line or main direction of the linear modules arranged in a ring.

[0041] Please refer to Figure 1 , the traditional linear module module is formed by the horizontal array of multiple linear modules. The module width of the linear module module depends on the spacing L between adjacent loads. Since the load is generally connected to the mover, the spacing L can also be approximately regarded as the distance between the two movers of two adjacent linear modules. When a large spacing L needs to be maintained between the loads, the module can have sufficient space to install standard parts such as guide rails and sensors by changing the spacing between two adjacent linear modules. When the spacing L needs to be designed small enough, in order to reduce the distance between the two movers, the traditional linear module module can only assemble two adjacent linear modules 1 closely together. However, on the one hand, this will result in insufficient installation space between two adjacent linear modules 1, making the installation of standard parts difficult and complex. On the other hand, if the spacing L is smaller than the distance between the two movers of two horizontally closely arranged linear modules 1, the traditional linear module module cannot be realized structurally at this time. Therefore, the size of the spacing L limits and restricts the design of the overall structure of the linear module module.

[0042] To solve the above problems, in an embodiment of the present application, the linear module includes a fixed part 11 and a movable part 12 that moves relative to the fixed part 11 in a first direction, where the first direction is the same as the extension direction of the axis; a plurality of loads are arranged side by side in a second direction; the linear module module 1000 further includes a plurality of load connectors 2 corresponding to the plurality of linear modules 1 one by one. The linear module 1 is drivingly connected to a load through the load connector 2, and the load connector 2 is connected to the movable part 12. It should be noted that "a plurality of loads are arranged side by side in the second direction" means that two or more loads are arranged in sequence along the second direction, so that the plurality of loads form a row or the center lines of the plurality of loads form a straight line. In this case, the linear module module 1000 can not only drive a plurality of loads, but also drive a single load using one linear module module 1000 to achieve the drive of a larger load. Each linear module 1 is connected to each load through the load connector 2. When the distance L between the loads is limited, the distance between the edge of the module of the linear module 1 and the axis (i.e., the length represented by a in Figure 3 can be adjusted, and load connectors 2 with different structures can be selected to drive a plurality of loads arranged side by side and spaced apart. Due to the characteristics of the annular array structure, a certain distance is always maintained between two adjacent linear modules 1, which can not only provide sufficient installation space but also meet the heat dissipation requirements of the linear module 1. Specifically, the distance L can be changed by adjusting the extending direction of the movable part 12 (i.e., the mover) (i.e., the mover extends outward or inward relative to the stator toward the annular array structure) and adjusting the position of the fixed part 11 (i.e., the stator) (the fixed parts approach or move away from each other). When the distance L between the loads needs to be designed to be small enough, the extending direction of the movable part 12 of the linear module 1 can be set toward the axis, and the distance between two adjacent linear modules 1 can be shortened as much as possible. Then, the load connectors 2 with different structures are used to connect to each load. In this way, in the above embodiment, the design of the traditional linear module module can be optimized, the requirements for the distance L between different loads can be met, and the influence of the relative distance L of the loads on the overall structure of the module is reduced.

[0043] It should be noted that since the required distance L is different in different cases, the positions of the fixed parts 11 and the extending directions of the movable parts 12 are different, resulting in the load connectors for correspondingly connecting the loads and the movable parts 12 having the same or different structures. However, to ensure that each load connector 2 can correctly connect a linear module 1 and a load and drive the load in the correct position, please refer to Figure 3 and Figure 7, in an embodiment of the present application, the load connecting member 2 includes a connecting portion 21 and a mounting portion 22 disposed at an angle to the connecting portion 1. The connecting portion 21 is connected to the movable portion 12, and the mounting portion 22 extends in the first direction and is connected to the load; wherein, a plurality of mounting portions 22 are arranged side by side in the second direction, and the second direction is perpendicular to the first direction. Please refer to Figure 3 , it can be understood that the angle between the connecting portion 21 and the mounting portion 22 of different load connecting members 2 can be different. For example, when the extending direction of the movable portion 12 of the linear module is flush with the second direction, the angle between the connecting portion 21 and the mounting portion 22 is 90°, and when the extending direction of the movable portion 12 is inclined with respect to the second direction, the angle between the connecting portion and the mounting portion is between 90° and 180°.

[0044] In an embodiment of the present application, the projections of the plurality of mounting portions 22 along the first direction can fall on a diameter of the annular array structure, that is, the plurality of loads connected by the plurality of mounting portions 22 are located at the center of the annular array structure. Please refer to the comparison as Figure 3 As shown in the structural diagram of the linear module module 1000 when n = 8, it can be known that since a plurality of linear modules 1 are arranged in an annular array, when the number of a plurality of linear modules 1 is greater than or equal to 2, there will be at least a pair of two linear modules 1 that are symmetrically distributed along the axis. When the load is located at the central position, the angles formed by the extending directions of the movable portions 12 of these two linear modules 1 and the second direction are the same. Therefore, the two load connecting members 2 connected to these two linear modules 1 can also adopt the same-shaped structure. Further, it can be inferred that if the number of a plurality of linear modules 1 is n (n≥2), when n is odd, the number of types of load connecting members 2 needs to be designed as (n + 1) / 2, and when n is even, the number of types of load connecting members 2 needs to be designed as n / 2. In this way, the types of parts can be saved and the production cost can be reduced.

[0045] In order to ensure the module volume, usually a single linear module 1 needs to be closely attached together in sequence, while achieving a larger stroke or load capacity, minimizing the overall size to the greatest extent, and improving the compactness and integration of the system. Therefore, in an embodiment of the present application, the number of a plurality of linear modules 1 is N, N≥2, where: when N = 2, the two linear modules 1 are symmetrically arranged along the axis; when N>2, any linear module 1 is in abutting contact with the adjacent two linear modules 1. In actual production and manufacturing, generally, the number of linear modules 1 needs to be determined according to the number of loads and the structure of the linear module 1 needs to be designed according to the distance L between the loads. Please continue to refer to Figure 3, taking the case when N > 2 as an example, if the distance from the moving part 12 (i.e., the mover) of the linear module 1 to the axis is a, then the width c of the linear module 1 = 2a * tan(180° / N). From the formula, it can be seen that when n is a fixed value, the larger a is, the larger the width c of the linear module 1. Therefore, when the number of loads and the distance L have been determined, to ensure that the volume of the module meets the design requirements, the length of a can be controlled so that the module width c meets the design requirements, and the length d dimension of the linear module 1 can be selected according to the assembly space, and the included angle α between adjacent linear modules 1 = 360° / N. In the above embodiment, abutting and contacting two adjacent linear modules 1 is to minimize the size of the distance a as much as possible while ensuring that the linear module module 1000 can meet the requirement of the distance L, so that the volume of the linear module module 1000 can be minimized, saving the assembly space, saving materials and manufacturing costs, and reducing the production cost.

[0046] To ensure that multiple linear modules 1 can maintain a stable position during operation and operation, in combination with Figure 4 As shown, in an embodiment of the present application, the linear module module 1000 further includes a base 3 and a limiting portion 4 provided on the base 3; the multiple linear modules 1 are limited and installed on the base 3 through the limiting portion 4. The limiting portion 4 can ensure that the linear module 1 is installed at a specific position on the base 3, so that the system can achieve a higher positioning accuracy, and it can make the maintenance of the linear module 1 more convenient. If the linear module 1 needs to be replaced or repaired, it can be operated more easily. The limiting portion 4 can be a buckle structure or a pin structure, etc.

[0047] In an embodiment of the present application, a plurality of first limiting grooves 41 are formed on the end surface of the base 3 close to the linear module 1. The plurality of first limiting grooves 41 are arranged in a circular array, and each first limiting groove 41 corresponds to a linear module 1. The linear module 1 is inserted into the first limiting groove 41; the plurality of first limiting grooves 41 form the limiting portion 4. By correctly setting the first limiting grooves 41, it can be ensured that the linear module 1 will not exceed the safety range during operation, thereby reducing the risk of accidents and improving the safety of the system. In addition, the first limiting grooves 41 are easy to manufacture and have low production costs. The position and range of the limit can be easily changed through the position and size of the first limiting grooves 41 to meet specific application requirements.

[0048] Further, in an embodiment of the present application, the depth of the first limiting groove 41 is A, and A ≥ 1.2 mm. The first limiting groove 41 with a depth greater than or equal to 1.2 mm can ensure that there is enough space when installing the linear module 1 and allow a certain margin to ensure the reliability and stability of the limiting function. If the depth is insufficient, it may cause the linear module 1 to be unable to be fully installed and positioned or be unstable, thus affecting the performance and safety of the system.

[0049] In order to ensure the volume of the module, traditional multi-slider linear modules need to tightly fit multiple linear modules 1 together. This design will cause the operating heat of the linear module 1 in the middle to be unable to dissipate effectively, resulting in problems such as high temperature rise. In the linear module module 1000 provided in the present application, since multiple linear modules 1 are arranged in an annular array structure, there is sufficient space between two adjacent linear modules 1. To accelerate the heat dissipation of the module, please refer to Figure 6 , in an embodiment of the present application, the linear module module 1000 further includes a heat dissipation structure 5. The heat dissipation structure 5 includes a plurality of cooling modules 51. The plurality of cooling modules 51 are arranged in an annular array and are spaced apart from each other. The plurality of cooling modules 51 are arranged in an interleaved manner with the plurality of linear modules 1. It should be noted that the interleaved arrangement means that the cooling modules 51 and the linear modules 1 are arranged in an interleaved manner so that they are interspersed or misaligned with each other, that is, one cooling module 51 is provided between two linear modules 1, or one linear module 1 is provided between two cooling modules 51, so as to optimize the space utilization and improve the heat dissipation efficiency of the overall system. Setting the heat dissipation mechanism can accelerate the heat dissipation efficiency, ensure the operating temperature of the module, and improve the overall heat dissipation capacity and working performance of the module.

[0050] In an embodiment of the present application, the linear module module 1000 further includes a base 3. The base 3 is used to support the plurality of linear modules 1 and the heat dissipation structure 5. The base 3 serves as a stable foundation, which can bear and support the weights of the plurality of linear modules 1 and the heat dissipation structure 5, and ensure that it can maintain a stable position during operation and operation. Further, a plurality of first limiting grooves 41 and a plurality of second limiting grooves 42 are formed on the end surface of the base 3 close to the linear module 1. The plurality of first limiting grooves 41 and the plurality of second limiting grooves 42 are arranged in an interleaved manner; wherein, each first limiting groove 41 corresponds to a linear module 1, and the linear module 1 is inserted into the first limiting groove 41; each second limiting groove 42 corresponds to a cooling module 51, and the cooling module 51 is inserted into the second limiting groove 42. By correctly setting the first limiting groove 41 and the second limiting groove 42, it can be ensured that the linear module 1 and the heat dissipation structure 5 will not exceed the safe range during operation, thereby reducing the risk of accidents and improving the safety of the system. In addition, the first limiting groove 41 and the second limiting groove 42 are easy to process and have low production costs, and the position and range of the limit can be easily changed by changing the position and size of the limiting groove to meet specific application requirements.

[0051] In an embodiment of the present application, the cooling module 51 includes a housing. A cooling flow channel is formed inside the housing. Two ends of the housing are respectively in abutting contact with two adjacent linear modules 1. The cooling flow channel is used to convey a cooling medium, such as a cooling liquid or a cooling gas. At the same time, two ends of this housing are connected to two adjacent linear modules 1 to ensure close contact between the cooling module 51 and other components, which may help improve the heat dissipation efficiency or ensure the stability during the operation of the device.

[0052] In an implementation of the present application, a plurality of the linear modules 1 and a plurality of the cooling modules 51 are spliced to form the linear module module 1000. The linear module module 1000 formed by the splicing method makes each component relatively independent, which makes it more convenient to maintain or add components, and greatly improves the maintainability and flexibility of the linear module module 1000.

[0053] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
