Description

Technical Field

[0001] The present invention relates to the technical field of linear motor modules, and more specifically, to an integrated externally embedded guide rail module. Background Art

[0002] A linear motor module is a device that converts electrical energy directly into mechanical energy of linear motion without any intermediate conversion structure. It is mainly composed of a moving stator, a guide rail, an encoder, and a sensor. The moving stator provides power, the guide rail is used to guide and support the load, the encoder realizes positioning and feedback, and the sensor acts as a limiter to prevent damage caused by misoperation. Existing conventional linear motor modules all use traditional rolling linear guides as part of the guide transmission. The structural size of each brand is similar and has a high degree of convergence. For this reason, the external dimensions of conventional linear motor modules are greatly affected by the linear guide.

[0003] The Chinese patent discloses a linear motor module with an externally embedded groove guide (Announcement No. CN214281188U), which includes a linear motor body, a sliding structure, a base, an end plate, and a cover plate. The linear motor body includes a slider, the base includes a bottom plate and two side plates, the two side plates are fixedly connected to the bottom plate to form a base cavity, the end plate is connected to the front and rear sides of the base, the end plate blocks the front and rear sides of the base cavity, the cover plate is arranged on the upper side of the base cavity, the end plate is connected to the cover plate so that the end plate supports the cover plate, the slider includes a main board and a sliding foot, the sliding foot is fixedly connected to the bottom of the main board, the sliding foot is arranged on the outside of the adjacent side plate, and the sliding foot is slidably connected to the outer wall of the adjacent side plate through the sliding structure. The sliding foot and the sliding structure are both located on the outside of the base, do not occupy the internal space of the base cavity, and are convenient to handle if the sliding structure fails; the cover plate, the end plate and the base are surrounded to form a base cavity, which can prevent foreign matter from entering the interior of the linear motor module, but the device integrates the slider part into the slide table, which is not convenient for disassembly and maintenance. At the same time, with the increasing application requirements of various industries, the requirements for the external dimensions of the modules are also increasing, gradually requiring smaller dimensions and larger loads. At the same time, the installation process of traditional rolling linear guides is relatively cumbersome. The assemblers use marble square gauges, micrometers and other tools on the marble platform to straighten and level them. This process is time-consuming and laborious. Summary of the invention

[0004] The object of the present invention is to provide an integrated externally embedded guide rail module to solve the problems raised in the above-mentioned background technology.

[0008] Furthermore, the motor magnet and the aluminum profile base are fixedly connected by bolts, and an air gap is left between the motor magnet and the motor coil.

[0009] By adopting the above technical solution, the air gap between the motor magnet and the motor coil ensures that the two components do not contact each other, effectively reducing the friction loss between the components.

[0010] Furthermore, the encoding component includes an encoder bracket fixedly mounted on the front side of the slide, and an encoder is fixedly mounted on the lower end of the encoder bracket by bolts.

[0011] By adopting the above technical solution and providing an encoding component, the encoder can realize real-time monitoring and control of parameters such as displacement, speed and acceleration, while ensuring the normal operation of the linear motor.

[0012] Furthermore, the photoelectric component includes a sensor bracket fixedly mounted on the rear side of the aluminum profile base, and a photoelectric sensor is fixedly mounted on the upper end of the sensor bracket.

[0013] By adopting the above technical solution, the photoelectric sensor can sense and detect the position of the photoelectric baffle. When the photoelectric baffle blocks the light, the control system controls and adjusts the whole according to the signal.

[0014] Furthermore, a pair of module end covers are fixedly installed at both ends of the aluminum profile base by bolts, and anti-collision blocks are fixedly installed on the upper sides of the two opposite sides of the two module end covers.

[0015] By adopting the above technical solution, the module end cover can play a certain sealing and protective role on the aluminum profile base, and can prevent foreign matter from entering the motor coil.

[0016] Furthermore, a module upper cover is fixedly mounted on the upper end of the module end cover by means of bolts, and a magnetic scale is fixedly mounted on the upper rear end of the aluminum profile base.

[0017] By adopting the above technical solution, the module cover can seal and protect the upper side of the slide.

[0018] Compared with the prior art, the advantages of the present invention are: 1. In the present invention, by providing a structure with a slide table and a special slider, the entire special slider and the slide table are separated from the aluminum profile base, and can be quickly disassembled and repaired, which is convenient for maintenance.

[0019] 2. In the present invention, by setting the structure of the grinding steel bars, only four grinding steel bars in the whole device are made of steel, which has a lower cost without affecting the service life, and effectively reduces the overall width, and the overall size is smaller while ensuring that the size of the motor remains unchanged.
