Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gripper technology, and in particular relates to an air-blown gripper. Background Technology
[0002] During the production process, electronic components need to be held by grippers and then placed on the PCB board by their own weight.
[0003] Traditional mechanical grippers have several drawbacks. Due to their complex mechanical transmission structure, traditional grippers struggle to respond quickly during start-up, stop-motion, and reversal operations. These inherent limitations prevent them from meeting the stringent requirements of rapid and precise gripping and placement in high-frequency operation scenarios. Frequent action delays not only significantly reduce production efficiency but also disrupt production line rhythms, leading to unstable product quality and becoming a key factor hindering modern high-efficiency production. Therefore, we propose an air-blown gripper. Utility Model Content
[0004] The purpose of this invention is to provide an air-blowing opening gripper to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides an air-blowing opening gripper, including a fixing post, and further comprising:
[0006] A limiting sleeve is sleeved on a fixed post. A sliding groove is provided inside the fixed post. A sliding post is slidably installed in the sliding groove. A spring that is fixed to the inner wall of the sliding groove is fixedly installed at the bottom of the sliding post.
[0007] A fixed gripper is fixedly installed on the top of a sliding column. A fixed strip is fixedly installed on the top of the sliding column. A rotating gripper is provided on the fixed strip. A first limiting post is inserted into the rotating gripper. One end of the first limiting post passes through the fixed strip and the rotating gripper and extends to the outside. The first limiting post and the fixed strip are inserted into each other.
[0008] A drive assembly, located within a fixed column, is used to drive the rotating gripper to rotate.
[0009] In this technical solution, the drive component can drive the rotating jaw to rotate, and the rotating jaw rotates on the first limiting post. When the rotating jaw rotates to the appropriate position, the material is placed between the fixed jaw and the rotating jaw. Then, the air compressor sucks away the gas in the pipeline. At this time, the sliding rod slides down, and the sliding rod drives the second limiting post to slide and rotate in the movable groove. The second limiting post pulls the rotating jaw to rotate through the movable groove, and the rotating jaw rotates on the first limiting post. Finally, the rotating jaw can clamp the material.
[0010] When the fixed gripper is compressed, it drives the sliding column to slide. The sliding column compresses the spring, which can buffer the compression force and prevent the compression force from being too great and causing damage to the rotating gripper or the fixed gripper. When the fixed gripper is no longer compressed, the sliding column slides upward and resets under the action of the spring rebound force. The set limit sleeve can limit the position of the gas delivery pipeline and prevent the gas delivery pipeline from being displaced excessively.
[0011] In the above technical solution, the driving component further includes:
[0012] A gas delivery trough is provided, which is located inside a fixed column and at the bottom of a sliding groove. A sliding rod is slidably installed inside the gas delivery trough, with the upper end of the sliding rod passing through the sliding column. A movable groove is provided inside the rotating gripper, and a second limiting post is inserted into the movable groove. One end of the second limiting post passes through the sliding rod and the movable groove and extends to the outside, and the second limiting post is inserted into the sliding rod.
[0013] In this technical solution, the pipe is first inserted into the fixed column. Then, high-pressure gas is transported into the fixed column through the pipe. After entering the gas conveying trough, the high-pressure gas squeezes the sliding rod and slides. The sliding rod drives the second limiting column to slide and rotate in the movable groove. The second limiting column drives the rotating jaw to rotate through the movable groove. At the same time, the rotating jaw rotates on the first limiting column. When the rotating jaw rotates to the appropriate position, the material is placed between the fixed jaw and the rotating jaw. Then, the air compressor sucks away the gas in the pipe. At this time, the sliding rod slides down. The sliding rod drives the second limiting column to slide and rotate in the movable groove. The second limiting column pulls the rotating jaw to rotate through the movable groove. At the same time, the rotating jaw rotates on the first limiting column. Finally, the rotating jaw can clamp the material.
[0014] In the above technical solution, two grooves are further provided on the circumferential sidewall of the sliding column, and a fixing rod that is fixed to the inner wall of the sliding groove is slidably installed in each of the two grooves.
[0015] In this technical solution, the two fixed rods slide within the two grooves respectively, which can limit the sliding of the sliding column and ensure that the sliding column can only slide vertically.
[0016] In the above technical solution, the limiting sleeve is further provided with a screw threaded on it, one end of which penetrates the limiting sleeve and is in close contact with the fixing post.
[0017] In this technical solution, when it is necessary to disassemble the limiting sleeve, simply use a tool to remove the screws, and then lift the limiting sleeve upwards. The operation is convenient and quick.
[0018] In the above technical solution, furthermore, both the second limiting post and the first limiting post are provided with limiting grooves, and limiting rings are snapped into both limiting grooves.
[0019] In this technical solution, when it is necessary to disassemble the rotating gripper, the two limiting rings are removed, then the first limiting post and the second limiting post are removed, and finally the rotating gripper can be removed.
[0020] In the above technical solution, a fixing ring is further fixedly installed on the fixing column.
[0021] In this technical solution, the fixed ring can limit the pipeline and ensure that the pipeline will not loosen when transporting gas.
[0022] In the above technical solution, the sliding rod is further fitted tightly against the inner wall of the gas conveying channel.
[0023] In this technical solution, it is ensured that the high-pressure gas will squeeze the sliding rod to slide after entering the gas delivery tank.
[0024] The beneficial effects of this utility model are:
[0025] 1. The air-blowing gripper opens and, through the set drive component, can drive the rotating gripper to rotate. At the same time, the rotating gripper rotates on the first limit post. When the rotating gripper rotates to the appropriate position, the material is placed between the fixed gripper and the rotating gripper. Then, the air compressor sucks away the gas in the pipeline. At this time, the sliding rod slides down and drives the second limit post to slide and rotate in the movable groove. The second limit post pulls the rotating gripper to rotate through the movable groove. At the same time, the rotating gripper rotates on the first limit post. Finally, the rotating gripper can quickly clamp the material.
[0026] 2. The air-blowing opens the gripper. When the fixed gripper is squeezed, the fixed gripper drives the sliding column to slide. The sliding column compresses the spring, which can buffer the squeezing force and prevent the squeezing force from being too large and causing damage to the rotating gripper or the fixed gripper. When the fixed gripper is no longer squeezed, the sliding column slides upward and resets under the action of the spring rebound force. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.
[0036] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0037] Example 1: This example provides an air-blowing opening gripper, including a fixing post 1, and also includes:
[0038] Limiting sleeve 2 is sleeved on fixed column 1. A sliding groove 3 is provided in the fixed column 1. A sliding column 4 is slidably installed in the sliding groove 3. A spring 5 is fixed to the inner wall of the sliding groove 3 at the bottom of the sliding column 4.
[0039] A fixed gripper 6 is fixedly installed on the top of the sliding column 4. A fixed strip 7 is fixedly installed on the top of the sliding column 4. A rotating gripper 9 is provided on the fixed strip 7. A first limiting post 8 is inserted into the rotating gripper 9. One end of the first limiting post 8 passes through the fixed strip 7 and the rotating gripper 9 and extends to the outside. The first limiting post 8 and the fixed strip 7 are inserted and engaged.
[0040] The drive assembly is located inside the fixed column 1 and is used to drive the rotating gripper 9 to rotate.
[0041] The drive component can drive the rotating gripper 9 to rotate, and the rotating gripper 9 also rotates on the first limiting post 8. When the rotating gripper 9 rotates to the appropriate position, the material is placed between the fixed gripper 6 and the rotating gripper 9. Then, the air compressor sucks away the gas in the pipeline. At this time, the sliding rod 11 slides down, and the sliding rod 11 drives the second limiting post 12 to slide and rotate in the movable groove 18. The second limiting post 12 pulls the rotating gripper 9 to rotate through the movable groove 18, and the rotating gripper 9 also rotates on the first limiting post 8. Finally, the rotating gripper 9 can clamp the material.
[0042] When the fixed clamp 6 is compressed, it drives the sliding column 4 to slide. The sliding column 4 compresses the spring 5, which can buffer the compression force and prevent the rotating clamp 9 or the fixed clamp 6 from being damaged due to excessive compression force. When the fixed clamp 6 is no longer compressed, the sliding column 4 slides upward and resets under the action of the spring 5 rebound force. The position of the gas conveying pipeline can be limited by the set limit sleeve 2 to prevent the gas conveying pipeline from being displaced excessively.
[0043] In this embodiment, the driving component includes:
[0044] A gas delivery channel 10 is provided inside a fixed column 1 and located at the bottom of a sliding channel 3. A sliding rod 11 is slidably installed inside the gas delivery channel 10. The upper end of the sliding rod 11 passes through the sliding column 4. A movable channel 18 is provided inside a rotating gripper 9. A second limiting post 12 is inserted into the movable channel 18. One end of the second limiting post 12 passes through the sliding rod 11 and the movable channel 18 and extends to the outside. The second limiting post 12 is inserted into the sliding rod 11.
[0045] First, the pipe is inserted into the fixed column 1. Then, high-pressure gas is delivered to the fixed column 1 through the pipe. After the high-pressure gas enters the gas delivery trough 10, it squeezes the sliding rod 11 and slides it. The sliding rod 11 drives the second limiting column 12 to slide and rotate in the movable groove 18. The second limiting column 12 drives the rotating jaw 9 to rotate through the movable groove 18. At the same time, the rotating jaw 9 rotates on the first limiting column 8. When the rotating jaw 9 rotates to the appropriate position, the material is placed between the fixed jaw 6 and the rotating jaw 9. Then, the air compressor sucks away the gas in the pipe. At this time, the sliding rod 11 slides down. The sliding rod 11 drives the second limiting column 12 to slide and rotate in the movable groove 18. The second limiting column 12 pulls the rotating jaw 9 to rotate through the movable groove 18. At the same time, the rotating jaw 9 rotates on the first limiting column 8. Finally, the rotating jaw 9 can clamp the material.

[0049] The two fixed rods 13 slide within the two grooves 17 respectively, which can limit the sliding of the sliding column 4 and ensure that the sliding column 4 can only slide vertically.
[0050] Example 3:
[0051] This embodiment provides an air-blowing opening gripper, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0052] In this embodiment, a screw 14 is threaded onto the limiting sleeve 2. One end of the screw 14 penetrates the limiting sleeve 2, and one end of the screw 14 is in close contact with the fixing post 1.

[0056] In this embodiment, both the second limiting post 12 and the first limiting post 8 have limiting grooves 15, and both limiting grooves 15 are fitted with limiting rings 16.

[0058] Example 5:
[0059] This embodiment provides an air-blowing opening gripper, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0060] In this embodiment, a fixing ring 19 is fixedly installed on the fixing column 1.
[0061] The fixed ring 19 can limit the pipe and ensure that the pipe will not loosen when transporting gas.
[0062] Example 6:
[0063] This embodiment provides an air-blowing opening gripper, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0064] In this embodiment, the sliding rod 11 is in close contact with the inner wall of the gas delivery channel 10.
[0065] Specifically, this ensures that after the high-pressure gas enters the gas delivery tank 10, it will compress the sliding rod 11 and allow it to slide.
[0066] Working principle: First, the pipe is inserted into the fixed column 1. The fixed ring 19 can limit the pipe to ensure that it will not loosen when transporting gas. Then, the high-pressure gas is delivered to the fixed column 1 through the pipe. After the high-pressure gas enters the gas delivery tank 10, it will squeeze the sliding rod 11 to slide. The sliding rod 11 drives the second limiting column 12 to slide and rotate in the movable groove 18. The second limiting column 12 drives the rotating jaw 9 to rotate through the movable groove 18. At the same time, the rotating jaw 9 rotates on the first limiting column 8. When the rotating jaw 9 rotates to the appropriate position, the material is placed between the fixed jaw 6 and the rotating jaw 9. Then, the air compressor sucks away the gas in the pipe. At this time, the sliding rod 11 slides down. The sliding rod 11 drives the second limiting column 12 to slide and rotate in the movable groove 18. The second limiting column 12 pulls the rotating jaw 9 to rotate through the movable groove 18. At the same time, the rotating jaw 9 rotates on the first limiting column 8. Finally, the rotating jaw 9 can clamp the material.
[0067] When the fixed clamp 6 is compressed, it drives the sliding column 4 to slide. The sliding column 4 compresses the spring 5, which can buffer the compression force and prevent the rotating clamp 9 or the fixed clamp 6 from being damaged due to excessive compression force. When the fixed clamp 6 is no longer compressed, the sliding column 4 slides upward and resets under the action of the spring 5 rebound force. At the same time, the two fixed rods 13 slide in the two grooves 17 respectively, which can limit the sliding of the sliding column 4 and ensure that the sliding column 4 can only slide vertically. The position of the gas conveying pipeline can be limited by the set limit sleeve 2 to prevent the gas conveying pipeline from being displaced excessively.
