Description

Technical Field

[0001] The utility model belongs to the technical field of mobile platforms, and specifically relates to a compact multi-output mobile platform. Background Art

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. Compared with the combination of a driving motor and a lead screw pair, its volume is much smaller. Therefore, linear motors are mostly used as power components for mobile platforms or mobile modules. Such as the publicly disclosed technical documents "CN117914094A, Dual-drive Gantry Linear Motor Platform" and "CN111146918A, A Dual-axis Linear Motor Module Platform", etc.; currently, these mobile modules can only move in a plane or achieve multi-axis movement in cooperation with other mobile components, and very long tracks need to be designed, making the overall volume very large.

[0003] It is not conducive to installation in positions with limited space, and the number of output ends is also relatively small. Multiple mobile modules need to be installed to meet production needs, which will further expand the occupied space and the production cost is also very high. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a compact multi-output mobile platform to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A compact multi-output mobile platform includes a bottom plate, on which an installation seat is fixedly provided. On opposite sides of the installation seat, a first linear motor and a second linear motor are respectively installed.

[0007] On the moving end of the first linear motor, a first moving plate is installed. Between the first moving plate and the installation seat, a first vertical sliding pair is provided. On the first moving plate, a third linear motor and a fourth linear motor with moving directions different from that of the first linear motor are installed. On the moving ends of the third linear motor and the fourth linear motor, a first sliding seat and a second sliding seat are respectively installed.

[0008] On the moving end of the second linear motor, a second moving plate is installed. Between the second moving plate and the installation seat, a second vertical sliding pair is provided. On the second moving plate, a fifth linear motor and a sixth linear motor with moving directions different from that of the second linear motor are installed. On the moving ends of the fifth linear motor and the sixth linear motor, a third sliding seat and a fourth sliding seat are respectively installed.

[0009] As a further technical solution, the bottom plate and the installation seat are combined to form a "T" shape, and a number of installation holes are provided on the bottom plate.

[0010] Further technical solution: Two limiting pads are provided on the bottom plate, and the limiting pads can respectively abut against the bottoms of the first moving plate and the second moving plate.

[0011] Further technical solution: A linear motor seven and a linear motor eight are respectively installed on opposite sides of the mounting seat, and the linear motor seven and the linear motor eight are respectively arranged in a staggered manner with the linear motor one and the linear motor two;

[0012] The moving ends of the linear motor seven and the linear motor eight are respectively installed with a third moving plate and a fourth moving plate. The third moving plate and the fourth moving plate vertically extend out of the end of the mounting seat, and a lamination platform is fixedly provided at the ends of the third moving plate and the fourth moving plate.

[0013] Further technical solution: A first position sensor is provided on one side of each of the first moving plate and the second moving plate, and a second position sensor for cooperating with the first position sensor is provided on one side of each of the third moving plate and the fourth moving plate.

[0014] Advantages of the present utility model:

[0015] During operation, first, the first moving plate and the second moving plate are respectively driven by the linear motor one and the linear motor two to move up and down to adjust the position. Since the first moving plate and the second moving plate are driven by two independent linear motors, the position can be adjusted separately. Then, the first sliding seat, the second sliding seat, the third sliding seat and the fourth sliding seat are respectively driven by the linear motor three, the linear motor four, the linear motor five and the linear motor six according to the actual situation, forming four independently operating output ends. The moving platform described in the present utility model is suitable for equipment with a short moving distance and multiple output requirements. The volume of the moving platform can be greatly reduced through the combination of multiple linear motors. Since all moving ends adopt a driving method, the movement is very flexible.

Detailed implementation manners

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0022] Please refer to Figures 1 - 3 ;

[0023] The moving platform described in the present utility model has the characteristics of small volume, compact structure and multiple outputs, and can meet the requirements of narrow installation space and multiple output controls; referring to Figure 1 , it specifically includes a bottom plate 11, on which a mounting seat 2 is fixedly provided. There is an included angle between the bottom plate 11 and the mounting seat 2. The bottom plate 11, as the component connected to the device, has a specific orientation determined according to the actual situation. Preferably, the bottom plate 11 and the mounting seat 2 are perpendicular to each other to form a "T" - shaped structure. A number of mounting holes 12 are provided on the bottom plate 11. Usually, the moving platform is pre - assembled and then installed in the device. Since the moving platform is relatively heavy as a whole, a lifting ring can be set in the mounting hole 12 for hoisting and transportation. In addition, the mounting hole 12 can also be used as the connection position between the bottom plate 11 and the device. After placing the moving platform on the device, the lifting ring is removed, and then a fixing part is passed through the mounting hole 12 to be connected to the device, so that the moving platform is fixedly installed on the device;

[0024] In this embodiment, a linear motor 31 and a linear motor 41 are respectively installed on two opposite sides of the mounting base 2. It should be noted that a linear motor generally consists of two parts: a linear motor body and a slide rail. The moving end of the linear motor specifically refers to the fixed end. If the linear motor body is fixed, then the slide rail is the moving end; if the slide rail is fixed, the linear motor body is the moving end. The moving end of the linear motor 31 is installed with a moving plate 32. A vertical sliding pair 33 is provided between the moving plate 32 and the mounting base 2. The linear motor 31 pushes the moving plate 32 to move up and down along the sliding pair 33, but the length of the sliding pair 33 does not exceed the length of the mounting base 2. A linear motor 34 and a linear motor 35, which are different from the moving direction of the linear motor 31, are installed on the moving plate 32. The number of the linear motor 34 and the linear motor 35 can be multiple. The moving ends of the linear motor 34 and the linear motor 35 are respectively installed with a slide seat 36 and a slide seat 37. Based on the moving direction of the moving plate 32, it can be known that the linear motor 31 outputs in the vertical direction, so the linear motor 34 and the linear motor 35 output in a non-vertical direction. The specific output direction can be determined according to the requirements of the actual device. However, as a standard moving platform, the linear motor 34 and the linear motor 35 preferably output in the horizontal direction and are perpendicular to the output direction of the linear motor 31.

[0025] The moving end of the linear motor 41 is installed with a moving plate 42. A vertical sliding pair 43 is provided between the moving plate 42 and the mounting base 2. The linear motor 41 pushes the moving plate 42 to move up and down along the sliding pair 43, but the length of the sliding pair 43 does not exceed the length of the mounting base 2. A linear motor five (not shown) and a linear motor 44, which are different from the moving direction of the linear motor 41, are installed on the moving plate 42. The number of the linear motor five and the linear motor 44 can be multiple. The moving ends of the linear motor five and the linear motor 44 are respectively installed with a slide seat 45 and a slide seat 46. Based on the moving direction of the moving plate 42, it can be known that the linear motor 41 outputs in the vertical direction, so the linear motor five and the linear motor 44 output in a non-vertical direction. The specific output direction can be determined according to the requirements of the actual device. However, as a standard moving platform, the linear motor five and the linear motor 44 preferably output in the horizontal direction and are perpendicular to the output direction of the linear motor 31.

[0026] Based on the above structure, a total of two independent modules are formed. Each independent module also has two independent small modules, which can control the direction and output separately to achieve multi-position adjustment.

[0027] It should be noted that the slide seat 36, the slide seat 37, the slide seat 45 and the slide seat 46 are respectively connected to an external device, and the external device is driven to move by the above four slide seats.

[0028] During operation, first, the first linear motor 31 and the second linear motor 41 drive the first moving plate 32 and the second moving plate 42 to move up and down respectively to adjust the position. Since the first moving plate 32 and the second moving plate 42 are driven by two independent linear motors, their positions can be adjusted separately. Then, the first sliding seat 36, the second sliding seat 37, the third sliding seat 45, and the fourth sliding seat 46 are separately driven by the third linear motor 34, the fourth linear motor 35, the fifth linear motor, and the sixth linear motor 44 according to the actual situation, forming four independently operating output ends. The moving platform of the present utility model is applicable to equipment with short moving distances and multiple output requirements. The combination of multiple linear motors can greatly reduce the volume of the moving platform. Since all the moving ends adopt a driving method, the movement is very flexible.

[0029] In the embodiment of the present utility model, the first sliding seat 36 and the second sliding seat 37 are respectively connected to the same third sliding pair. Through the third sliding pair, the positions of the first sliding seat 36 and the second sliding seat 37 can be limited, and at the same time, the movement of the first sliding seat 36 and the second sliding seat 37 can be made smoother. The third sliding seat 45 and the fourth sliding seat 46 are respectively connected to the same fourth sliding pair. Through the fourth sliding pair, the positions of the third sliding seat 45 and the fourth sliding seat 46 can be limited, and at the same time, the movement of the third sliding seat 45 and the fourth sliding seat 46 can be made smoother.

[0030] In the embodiment of the present utility model, two limiting pads 13 are provided on the bottom plate 11. The limiting pads 13 can respectively abut against the bottoms of the first moving plate 32 and the second moving plate 42. The two limiting pads 13 are used to limit the descending positions of the first moving plate 32 and the second moving plate 42 to prevent them from touching the bottom plate 11.

[0031] In the embodiment of the present utility model, referring to Figure 2 and Figure 3 ; a seventh linear motor 51 and an eighth linear motor (not shown) are respectively installed on two opposite sides of the mounting seat 2. The seventh linear motor 51 and the eighth linear motor are arranged in a staggered manner with the first linear motor 31 and the second linear motor 41. Assuming that the mounting seat 2 is a cuboid, the first linear motor 31 and the second linear motor 41 are installed on one opposite side, while the seventh linear motor 51 and the eighth linear motor are installed on the opposite side. The moving ends of the seventh linear motor 51 and the eighth linear motor are respectively installed with a third moving plate 52 and a fourth moving plate 53. The third moving plate 52 and the fourth moving plate 53 vertically extend out of the end of the mounting seat 2, and a laminated platform 54 is fixedly provided at the ends of the third moving plate 52 and the fourth moving plate 53. In this embodiment, a fifth independent output end is formed;

[0032] Based on the implementation manners of all the above structures, the formed mobile platform can be applied in lithium battery stacking production equipment. A mobile platform is also required in the lithium battery stacking production equipment. For details, reference can be made to the public technical document "CN114824499A, Main driving equipment, system and control method applicable to lithium battery stacking". The mobile platform in this application is the "main driving equipment" in the cited document. It can be seen from the cited document that a large number of driving motors, ball screws and other parts are used as the mobile device, and a very large installation space needs to be reserved, and there are also many parts, making the assembly very inconvenient;

[0033] In the present utility model, by largely adopting linear motors as the driving components, the installation is more convenient and the occupied volume is smaller without loss of precision.

[0034] In the embodiment of the present utility model, a position sensor one 61 is provided on one side of each of the moving plate one 32 and the moving plate two 42, and a position sensor two 62 is provided on one side of each of the moving plate three 52 and the moving plate four 53. The moving distances of the moving plate three 52 and the moving plate four 53 are limited by the mutual cooperation of the position sensor one 61 and the position sensor two 62.

[0035] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0036] In addition, it should be understood that although this specification is described according to the implementation manners, not every implementation manner only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
