Description

Technical Field

[0001] The present invention relates to the technical field of industrial automation, in particular to a pneumatic braking method for a linear rotary motor. Background Art

[0002] In modern industrial automation, linear rotary motors (LRMs) are widely used in various precision machinery due to their efficient power transmission and precise motion control. Braking devices, as key components for the safe and stable operation of LRMs, have a direct impact on the overall efficiency and safety of the equipment.

[0003] Traditional linear rotary motor brakes have exposed numerous problems in practical applications. For example, the common brake structure design results in a large distance between the brake pad and the supporting mechanism. This results in a large spatial distance to achieve braking, which weakens the braking force and response speed. In addition, due to the traditional drive method, the brake pad and the supporting mechanism are not pushed into contact quickly enough, resulting in reduced braking effectiveness. In some applications where braking timeliness is extremely important, such as high-speed automated production lines or precision machining equipment, this deficiency can cause serious production accidents, resulting in equipment damage and production stagnation.

[0004] Furthermore, the greater distance between the brake pad and the support mechanism results in unnecessary energy loss during braking, reducing energy efficiency. Furthermore, the larger braking space required limits the miniaturization and compactness of the equipment, increasing its overall size and cost. Summary of the Invention

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-4 The present invention provides a technical solution: a pneumatic braking method for a linear rotary motor, comprising the following steps:

[0037] S1: Motor 1 drives the carrying mechanism 4 to slide in the slider 2. Motor 1 is used to drive the carrying mechanism 4 to slide up and down in the slider 2 and the mounting mechanism 3 when the device is running to complete the work;

[0038] S2: When the motor 1 needs to be braked, the mounting mechanism 3 uses the back plate 5 to provide air intake for the motor 1, so that the mounting mechanism 3 can have a certain amount of airflow to push the brake pad 33;

[0039] S3: The driver 31 pushes the brake pad 33 to brake the supporting mechanism 4. The driver 31 pushes the push rod 32 through the airflow, so that the brake pad 33 comes into contact with the supporting mechanism 4, thereby achieving a braking effect on the supporting mechanism 4.

[0040] S4: The reset rod 34 pulls the brake pad 33 to reset. The reset rod 34 is pulled by the reset spring 35 to reset the brake pad 33, so that the brake of the supporting mechanism 4 can be braked again in sequence. Steps S2, S3, and S4 are repeated in sequence.

[0041] When the pneumatic brake device of the linear rotary motor is in use, when the pneumatic brake device of the linear rotary motor needs to brake, the air compressor driver 31 provided on the back plate 5 starts to work, draws air through the air inlet 51, and uses air pressure to drive the push rod 32 connected thereto, and the push rod 32 then pushes the brake pad 33 to be inserted into the slide groove 41 of the supporting mechanism 4; since the slider 2 and the mounting mechanism 3 are at least two mirror images arranged on both sides of the supporting mechanism 4, and the number of the drivers 31 is four, they are arranged in groups of two on both sides of the supporting mechanism 4, which can enhance the braking effect. At the same time, the drivers 31 on the same side work synchronously through the second connecting pipe 53 connected to the air outlet 54, and the air enters through the air inlet 51. The first connecting pipe 52 is connected to the second connecting pipe 53 and then enters each driver 31; because the brake pad 33 and the supporting mechanism 4 are meshed with each other in shape, the friction between the two generates sufficient friction force, so that the original moving speed of the supporting mechanism 4 is gradually reduced under the drive of the motor 1 to achieve braking; after the braking is completed, the reset rod 34 connected to the brake pad 33 is pulled back by the reset spring 35 connected to the mounting mechanism 3 at one end, thereby driving the brake pad 33 to move backward to complete the reset, ensuring the safe and stable operation of the linear rotary motor system and the recycling of the brake device, and the housing 6 protects and carries the remaining structures throughout the process, ensuring that each device is connected and fixed to avoid accidents during use.

[0042] The detailed steps of S2 include:

[0043] S21: Air flows into the first connecting pipe 52 through the air inlet 51 . The air inlet 51 is provided on the top of the back plate 5 , allowing air to enter the interior of the back plate 5 .

[0044] S22: The second connecting pipe 53 is used to divide the airflow of the installation mechanism 3. The second connecting pipe 53 is connected to the first connecting pipe 52 to evenly divide the airflow into two parts, ensuring that all four installation mechanisms 3 can receive airflow.

[0045] S23: The air enters all the mounting mechanisms 3 through the air outlet 54 so that the air flow can enter the mounting mechanisms 3 through diversion, and finally all the mounting mechanisms 3 can push the brake pads 33 toward the supporting mechanism 4 together.

[0046] The drivers 31 on the same side work synchronously through the second connecting pipe 53 connected to the air outlet 54 . Air enters the first connecting pipe 52 through the air inlet 51 , and then enters the driver 31 after connecting to the second connecting pipe 53 .

[0047] The back plate 5 is provided with an air inlet 51, a first connecting pipe 52, a second connecting pipe 53 and an air outlet 54. The air inlet 51 is used to allow air to enter the back plate 5, thereby connecting to the mounting mechanism 3, ensuring that the mounting mechanism 3 can have airflow to synchronously push the brake pad 33 close to the supporting mechanism 4. The air inlet 51 is provided on the outside of the back plate 5 and is connected to the first connecting pipe 52 provided in the back plate 5. The first connecting pipe 52 is mainly used to connect the air inlet 51 and the second connecting pipe 53, so that the airflow can be equally divided, thereby ensuring that the four drivers 31 can synchronously push the brake pad 33. The first connecting pipe 52 is connected to at least two air outlets 54. There are four air outlets 54, which are used to connect the two second connecting pipes 53 and the four drivers 31 respectively, ensuring that the drivers 31 can push the brake pad 33 synchronously. The actuator 31 can receive the airflow in the second connecting pipe 53, the air outlet 54 is connected to the mounting mechanism 3, the first connecting pipe 52 is connected to the second connecting pipe 53, and the second connecting pipe 53 is also connected to at least two air outlets 54. The arrangement method matches the installation position of the driver 31. Such a design can reduce the loss of airflow, ensure the normal operation of the driver 31, and reduce the occupied area of ​​the device. The number of air outlets 54 is consistent with that of the mounting mechanism 3, at least two, and is arranged in a mirror queue. The mounting mechanism 3 includes a driver 31 arranged outside the back plate 5. The driver 31 is a cylinder. Compared with the traditional pushing device, the cylinder has a faster and better braking effect. A push rod 32 is provided on the driver 31, and a brake pad 33 is connected to one end of the push rod 32.

[0048] The detailed steps for S3 include:

[0049] S31: All the actuators 31 use the air outlet 54 to suck air, and push the push rod 32 toward the carrying mechanism 4, so that the brake pad 33 contacts the carrying mechanism 4, thereby achieving the effect of braking the carrying mechanism 4;

[0050] S32 : As the driver 31 pushes the brake pads 33 to move inward, all the brake pads 33 come into contact with the outer sides of the supporting mechanism 4 , braking the supporting mechanism 4 .

[0051] The mounting mechanism 3 also includes a return spring 35 arranged inside the mounting mechanism 3. The number of the return springs 35 is consistent with the number of the return rods 34, and they are respectively arranged on the two return rods 34. When the return rods 34 are pushed inward, the return springs 35 pull the return rods 34 to move backward, thereby driving the brake pads 33 to move backward to complete the reset operation. The return springs 35 are provided with return rods 34, and the return rods 34 are connected to the brake pads 33.

[0052] After braking is completed, the reset rod 34 connected to the brake pad 33 is pulled back by the reset spring 35 connected to the mounting mechanism 3 at one end thereof, thereby driving the brake pad 33 to move backward to complete the reset, ensuring the safe and stable operation of the linear rotary motor system and the recycling of the brake device.

[0053] The detailed steps of S4 include:

[0054] S41: After the brake pad 33 is pushed by the push rod 32 and contacts the carrier mechanism 4 to brake the carrier mechanism 4, the driver 31 drives the push rod 32 to push the brake pad 33 and contact the carrier mechanism 4, thereby achieving a braking effect on the carrier mechanism 4;

[0055] S42: The reset spring 35 pulls the brake pad 33 to reset through the reset rod 34, making it convenient to repeat steps S2, S3, and S4 in sequence.

[0056] A sliding groove 41 is provided on the supporting mechanism 4 , and the size of the sliding groove 41 matches that of the brake pad 33 .

[0057] Because the brake pad 33 and the supporting mechanism 4 are meshed with each other in shape, the friction between the two generates sufficient friction force, so that the original moving speed of the supporting mechanism 4 is gradually reduced under the drive of the motor 1 to achieve braking; after braking is completed, the reset rod 34 connected to the brake pad 33 is pulled back under the action of the reset spring 35 connected to the mounting mechanism 3 at one end, thereby driving the brake pad 33 to move backward to complete the reset, ensuring the safe and stable operation of the linear rotary motor system and the recycling of the brake device, while the housing 6 protects and supports the remaining structures throughout the process, ensuring that each device is connected and fixed to avoid accidents during use.
