[0002] Linear modules, also known as linear modules, linear slides, etc., are widely used in automated production lines, machine tools, robots and other fields; the structure of linear modules mainly includes motors, transmission devices, guide devices and actuators. The motor is the power source of the linear module. The transmission device can convert the rotational motion of the motor into linear motion. The common structure is a ball screw structure. The guide device can ensure the motion accuracy and stability of the linear module, and the actuator is the device for the motion of the linear module.
[0003] However, the existing linear modules on the market mainly adopt the structure of motor-driven lead screw reciprocating motion or motor-driven synchronous belt reciprocating motion, which not only leads to a larger overall length of the existing module, but also a relatively slow movement speed. Utility Model Content
[0004] The problem to be solved by the utility model is to provide a two-stage speed module. Based on the characteristics of belt transmission, the movement of one stage module itself drives the second stage module to move through the second transmission mechanism adopting the belt transmission structure. It not only has the advantages of high speed, high precision and small size, but also can save materials and greatly improve work efficiency.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] In a preferred embodiment of the utility model, a driving motor is also fixedly mounted on the bottom plate, and an output end of the driving motor is coaxially connected to one of the first pulleys.
[0011] In a preferred embodiment of the present invention, the lengths of the first-stage module and the second-stage module are equal, and the axial directions of the first pulley and the second pulley are perpendicular to each other.
[0012] In a preferred embodiment of the utility model, the guide mechanism includes two groups of sliding components arranged opposite to each other, and the two groups of sliding components are respectively installed on the first module and the second module, and the sliding end of the sliding component located on the first module is connected to the second module, and the sliding end of the sliding component located on the second module is connected to the first module.

Beneficial Effects

DETAILED DESCRIPTION
[0019] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0020] like Figure 1-Figure 3 As shown, a two-stage double-speed module comprises a first-stage module 1 and a second-stage module 2 which are relatively arranged above a base plate, the two are slidably connected via a guide mechanism 3, and a loading platform 6 is fixedly mounted on the second-stage module 2; a first transmission mechanism 4 for driving the first-stage module 1 to move in a straight line direction is arranged on the base plate; a second transmission mechanism 5 for driving the second-stage module 2 to move in a straight line direction relative to the first-stage module 1 is arranged on one side of the first-stage module 1.
[0021] Specifically, the first module 1 and the second module 2 both adopt existing profiles; the first module 1 is located above the base plate, the second module 2 is located above the first module 1, and the first module 1 and the second module 2 are slidably connected through the guide mechanism 3, and a corresponding sliding mechanism is also provided between the first module 1 and the base plate, including a slide rail and a guide block that cooperate with each other, the slide rail is fixedly installed at the bottom of the first module 1, the guide block is fixedly installed on the base plate, and the guide block is slidably connected to the slide rail; when the first transmission mechanism 4 drives the first module 1 to move in a straight line, the first module 1 and the second module 2 move synchronously, and the second transmission mechanism 5 can drive the second module 2 to move in a straight line relative to the first module 1, so that when the linear telescopic stroke is equal, the two-stage double-speed module is compared with the existing linear module, not only has a smaller dimension in the length direction, but also the loading platform 6 can obtain a faster movement speed, thereby improving the efficiency of cargo handling.
[0022] As mentioned above, the second transmission mechanism 5 includes a rotatable second synchronous belt 52, both ends of which are connected to a section module 1 through a second pulley 51; and one side of the second synchronous belt 52 is fixedly connected to the base plate through a second clamping plate 53, and the other side is fixedly connected to a section module 1 through a third clamping plate 54, and the loading platform 6 is installed at one end of the second section module 2 away from the third clamping plate 54.
[0023] The second pulley 51 is rotatably mounted on one side of the first module 1 adjacent to the second module 2, and the two second pulleys 51 are respectively located at the two ends of the inner side of the second synchronous belt 52 to form a belt transmission structure; in this structure, the closed-loop synchronous belt has two sides, and the moving directions of the two sides are always opposite.
[0024] Driven by the first transmission mechanism 4, the first module 1 moves in a straight line relative to the base plate. Since the second pulley 51 is installed on the first module 1, the second transmission mechanism 5 as a whole can move with the first module 1; however, a lower part of the second synchronous belt 52 is fixedly connected to the base plate via the second clamping plate 53, that is, a part of the second synchronous belt 52 is stationary relative to the base plate. Therefore, under the action of the second pulley 51, the second synchronous belt 52 can also rotate relative to the first module 1, and an upper part thereof is fixedly connected to the second module 2 via the third clamping plate 54, thereby pulling the second module 2 to move in the same direction relative to the first module 1, so that the loading platform 6 on the second module 2 moves twice the distance of the first module 1.
[0025] As mentioned above, the first transmission mechanism 4 includes a first synchronous belt 42 which is parallel to the second synchronous belt 52 and can rotate. Both ends of the first synchronous belt 42 are connected to the base plate through the first pulley 41, and one side of the first synchronous belt 42 is fixedly connected to a section of the module 1 through the first clamping plate 43.
[0026] The two first pulleys 41 are respectively located at the two ends of the inner side of the first synchronous belt 42 to form an existing belt transmission structure; similarly, the moving directions of the two sides of the first synchronous belt 42 are opposite, and the linear motion of one side is utilized, and it is fixedly connected to a section of the module 1 through the first clamping plate 43, so that a section of the module 1 can be linearly driven on the base plate.
[0027] Furthermore, a driving motor 44 is fixedly mounted on the bottom plate, and the output end of the driving motor 44 is coaxially connected to one of the first pulleys 41. The difference from the second transmission mechanism 5 is that the synchronous belt of the first transmission mechanism 4 is realized by the driving motor 44 driving one of the pulleys to rotate, while the synchronous belt of the second transmission mechanism 5 is a part of which is fixedly connected to the bottom plate. While a section of the module 1 drives the first pulley 41 to move, the first pulley 41 itself can also rotate around the axis, thereby realizing the rotation of the second synchronous belt 52 within a certain range.
[0028] Among them, the driving motor 44 preferably adopts a servo motor, and the length of the first module 1 and the second module 2 are equal, and the axial directions of the first pulley 41 and the second pulley 51 are perpendicular to each other. The axis of the first pulley 41 is perpendicular to the bottom plate, which can facilitate the installation of the driving motor 44, and the axis of the second pulley 51 is perpendicular to the side of the first module 1, and the purpose is also to facilitate installation.
[0029] As mentioned above, the guide mechanism 3 includes two sets of sliding components arranged opposite to each other, and the two sets of sliding components are respectively installed on the first module 1 and the second module 2, and the sliding end of the sliding component located on the first module 1 is connected to the second module 2, and the sliding end of the sliding component located on the second module 2 is connected to the first module 1.
[0030] The two sets of sliding components are respectively arranged on the opposite sides of the first module 1 and the second module 2, and the two are staggered and connected, which can not only realize the functions of guiding and reducing friction and wear, but also use the two sets of relative sliding components as the guiding mechanism 3, and its structure is more stable. Sufficient space can be reserved between the first module 1 and the second module 2 to facilitate the assembly of other components.
[0031] Furthermore, the sliding assembly includes a guide rail 31 and a slider 32 slidably mounted on the guide rail 31. The guide rails 31 of the two sets of sliding assemblies are respectively fixedly mounted on the first module 1 and the second module 2, and the slider 32 is respectively correspondingly arranged at the opposite ends of the first module 1 and the second module 2.
[0032] The slider 32 is the sliding end of the sliding assembly. There is one slider in each guide rail 31 of the sliding assembly, and only one slider 32 is slidably installed on each guide rail 31. The two guide rails 31 of the guide mechanism 3 are respectively fixedly installed on the opposite sides of the first module 1 and the second module 2, that is, they are respectively installed on the top of the first module 1 and the bottom of the second module 2. The slider 32 located on the first module 1 is fixedly connected to the second module 2 through an L-shaped support plate, and the slider 32 located on the second module 2 is fixedly connected to the first module 1 through an L-shaped support plate, and the two sliders 32 are staggered at the opposite ends of the first module 1 and the second module 2.
[0033] The guide rail 31 is parallel to the length direction of the first module 1 and the second module 2, and when the second module 2 moves relative to the first module 1, the two sliders 32 move in opposite or opposite directions along their respective guide rails 31. The guide mechanism 3 can also limit the slider 32 through the L-shaped support plate, which can prevent the slider 32 from leaving the guide rail 31 and prevent the occurrence of safety accidents.
[0034] Working principle:
[0035] The driving motor 44 drives one of the first pulleys 41 to rotate, so that the first synchronous belt 42 rotates; one section module 1 is connected to one of the sides of the first synchronous belt 42 through the first clamping plate 43, so when the first synchronous belt 42 moves, it will drive the one section module 1 to move in the same direction; because one end of the second clamping plate 53 is fixedly connected to the bottom plate, and the other end is fixedly connected to the lower side of the second synchronous belt 52, when the one section module 1 moves, it will pull the second synchronous belt 52 to rotate, and the second section module 2 is fixedly connected to the upper side of the second synchronous belt 52 through the third clamping plate 54, so the second section module 2 can move along the guide mechanism 3 in the movement direction of the one section module 1 under the pull of the upper side of the second synchronous belt 52, so that the loading platform 6 on the second section module 2 moves twice the distance of the first section module 1.
[0036] In summary, this module is improved and redesigned to change the shortcomings of the existing module, such as poor transmission efficiency, slow speed and large space occupation. The module structure is more compact, easy to install and has a wider range of applications. The two-stage module can reduce the original length by half and double the speed, so as to achieve the fastest movement in the smallest space.
[0037] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
