Description

Technical Field

[0001] The present application relates to the technical field of tightening and assembling, and in particular to a nail body tightening device and a use method thereof. Background Art

[0002] The nail gun can be used to tighten the nail body placed in the preset position, thereby realizing the assembly of the equipment. During the use of the nail gun, the gun head of the nail gun can be used to limit the position of the nail body. When the gun head of the nail gun is abnormally opened, the nail body delivered to the gun head is easy to fly out of the gun head. Summary of the invention

[0003] The present application provides a nail body tightening device and a method of use, which are intended to improve the problem of the nail body flying out due to abnormal opening of the gun head when the nail gun is in use.

[0004] In order to achieve the above technical effects, a technical solution adopted by the present application is to provide a nail gun, comprising:

[0005] main body;

[0006] The gun head comprises a first part and a second part, a nail body channel for outputting the nail body is formed between the first part and the second part; the first part and the second part are respectively movably connected to the main body;

[0007] The clamping assembly comprises a first driving device and a clamping arm, wherein the clamping arm is movably arranged outside the first part and the second part; the first driving device is connected to the main body, and the first driving device drives the clamping arm to approach and clamp the outside of the first part and the second part; the clamping arm drives some components of the first driving device to move when the first part and the second part are separated by force; and

[0008] A detection component connected to the main body or the first driving device, the detection component is used to obtain a moving distance signal of the clamping arm;

[0009] The nail feeding component is electrically connected to the detection component and is used to feed the nail body to the nail body channel. The nail feeding component is used to output or stop outputting the nail body according to the moving distance signal.

[0010] In the example of the present application, a gun head is formed by using a first part and a second part. When the first part and the second part move relative to the main body, the opening of the nail body channel can be changed accordingly so that the nail body can move outward from the gun head; the clamping assembly is used to clamp the outside of the first part and the second part, and the first part and the second part are limited and clamped by the clamping assembly. When the nail body is input into the nail body channel, the movement of the first part and the second part can be limited by the clamping assembly, thereby facilitating the control of the opening of the nail body channel when the nail body is input; by using a detection assembly to detect the moving distance signal of the clamp arm, the working state of the nail feeding assembly can be easily controlled.

[0011] The nail feeding assembly is used to stop feeding the nail body to the nail body channel when a moving distance signal of the clamp arm when the first part and the second part are separated by force is greater than a first preset value.

[0012] In this example, when the clamp arm is subjected to the force of the first part and the second part, so that the movement distance signal when the clamp arm is opened is greater than the first preset value, the nail feeding assembly can be controlled to stop feeding the nail body to the nail body channel, thereby reducing the possibility of the nail body flying out due to abnormal opening of the gun head when inputting the nail body.

[0013] Among them, the nail body tightening equipment also includes:

[0014] The alarm component is electrically connected to the detection component, and is used to receive the moving distance signal and to give an alarm when the detection component detects that the moving distance signal of the clamping arm reaches a first preset value when the first part and the second part are separated by force.

[0015] In this example, when the movement distance signal of some components exceeds the first preset value, it indicates that there may be a problem of excessive movement distance between the first part and the second part, the opening of the nail body channel may exceed the preset range, and the gun head may be abnormally opened. By controlling the alarm component to issue an alarm, it is convenient to prompt the staff to reduce the possibility of the nail body flying out due to abnormal opening of the gun head.

[0016] There are two clamping arms, and the first driving device is respectively connected to the two clamping arms. The first driving device is used to drive the two clamping arms to approach each other and clamp the outside of the first part and the second part respectively. When the first part and the second part are separated by force, the two clamping arms drive some parts of the first driving device to move.

[0017] In this example, two clamping arms cooperate with each other, so that the first part and the second part can be limited by the two clamping arms respectively, which can improve the control accuracy of the clamping assembly over the first part and the second part.

[0018] Among them, the first driving device is a parallel cylinder, some components of the first driving device are piston rods of the parallel cylinder, and some components are connected to the clamping arm. When the first driving device drives some components to move along the first direction, the clamping arm is clamped on the outside of the first part and the second part. When the first part and the second part are separated by force, the clamping arm drives some components to move in the opposite direction of the first direction.

[0019] In this example, by adopting a parallel cylinder, the control difficulty of the first drive device can be reduced and the controllability of the moving stroke of the clamp arm can be improved; when the clamp arm approaches the first part and the second part, so that the opening of the nail body channel decreases, the piston rod of the parallel cylinder moves along the first direction, and when the first part and the second part are forced to move away from each other so that the opening of the nail body channel increases, the clamp arm opens under the action of the first part and the second part, and at this time the clamp arm pushes the piston rod of the parallel cylinder, so that the piston rod of the parallel cylinder can move in the opposite direction of the first direction.

[0020] The detection component is connected to some components of the first driving device, and is used to detect motion signals of some components, thereby obtaining movement distance signals of the clamping arm.

[0021] In this example, by detecting the motion signals of some components, the movement distance signals of the clamping arms can be indirectly obtained according to the motion signals of some components. On the one hand, it can facilitate the installation of the detection component, and on the other hand, it can simplify the detection method of the detection component.

[0022] The first drive device has a solenoid valve. When the solenoid valve is turned on, the first drive device can drive the clamping arm to approach and clamp the outside of the first part and the second part. When the solenoid valve is closed, the first drive device does not exert force on the clamping arm.

[0023] In this example, the operation of the first drive device can be controlled by controlling the state of the solenoid valve, so that the first drive device can be used to generate driving force for some components, or the first drive device does not generate driving force for some components. When the first drive device generates driving force for some components, the first drive device can be used to drive the some components to move along the first direction, thereby making the clamping arm close to the first part and the second part. When the first drive device does not generate driving force for some components, some components can be in a relaxed state. When the clamping arms are moved away from each other by external force, the some components can be driven to move in the opposite direction of the first direction.

[0024] Among them, the nail body tightening equipment also includes:

[0025] The nail body detection component is connected to the gun head and is used to detect whether the nail body output by the nail feeding component has reached the nail body channel; the solenoid valve is electrically connected to the nail body detection component, and the solenoid valve is used to close when the nail body detection component detects that the nail body output by the nail feeding component has reached the nail body channel.

[0026] The nail body detection component in this example can be used to detect whether the nail body output by the nail feeding component reaches the nail body channel. When the nail body output by the nail feeding component reaches the nail body channel, the solenoid valve can be controlled to close so that the first drive device no longer exerts force on some components, and the clamping arm no longer restricts the first part and the second part. In the subsequent nail tightening process, the first part and the second part can be moved away from each other to facilitate the output of the nail body.

[0027] The main bodies include:

[0028] Support;

[0029] A nail gun connected to the support;

[0030] An inner sleeve, the nail gun is drivingly connected to the inner sleeve to provide torque to drive the inner sleeve to rotate relative to the gun head, and the nail body channel is open at one end facing the nail gun; and

[0031] The second driving device is connected to the nail gun driving device, and is used to drive the nail gun to penetrate into the nail body channel or move out of the nail body channel along the axial direction of the nail body channel.

[0032] In this example, by setting a support, the nail gun can be conveniently installed on a preset device to facilitate the fixation of the nail gun; the inner sleeve can cooperate with the nail gun so that the nail gun can be used to drive the inner sleeve to rotate, and the second driving device can be used to drive the nail gun to move. When the nail gun moves, the inner sleeve can synchronously move in the direction of the gun head, so that the inner sleeve can cooperate with the nail body; by driving the inner sleeve to rotate with the nail gun, the nail body can be tightened.

[0033] Among them, nail guns also include:

[0034] The reset member is connected to the support; the reset member is also connected to the first part and the second part, and is used to generate a force for the first part and the second part to fit each other.

[0035] The reset member in this example can be used to reset the first part and the second part so that the first part and the second part can have a tendency to close together, thereby resetting the first part and the second part, thereby reducing the possibility of the nail body flying out due to excessive opening of the nail body channel.

[0036] The reset member is annularly sleeved on the outer sides of the first part and the second part.

[0037] In this example, by sleeve-arranging the reset member on the outer sleeve, the first part and the outside of the second part, the reset member can generate an elastic force on the first part and the second part, so that the first part and the second part have a tendency to approach and fit each other.

[0038] The main body also includes:

[0039] The support member is connected between the support and the gun head. A through hole connected to the nail body channel is opened on the support member. The second driving device is used to drive the nail gun to pass through the through hole and the nail body channel in sequence along the axial direction of the nail body channel or move out of the nail body channel; the first part and the second part are respectively rotatably connected to the support member.

[0040] The support member in this example can be used as an intermediate connecting member between the gun head and the support, and the support member can be easily connected to the gun head to facilitate the connection and fixation of the outer sleeve and the gun head.

[0041] Among them, the side walls of the support member corresponding to the first part and the second part are respectively provided with locking grooves; the first part and the second part are respectively provided with protrusions at one end facing the main body, and the protrusions are provided with a rotating shaft at one end close to the nail gun, and the rotating shafts are respectively rotatably embedded in the corresponding locking grooves.

[0042] The locking groove in this example can form a space for the protrusion to rotate, so that the rotation axis of the protrusion can at least partially rotate in the locking groove, thereby reducing the space required for the rotation axis and helping to improve the compactness of the structure.

[0043] Among them, the side walls corresponding to the first part and the second part of the support are respectively provided with clearance grooves, and the clearance grooves are respectively extended from the corresponding locking grooves to the end of the support away from the nail gun; the protrusions of the first part and the second part are respectively rotatably embedded in the corresponding clearance grooves.

[0044] The clearance groove in this example can be used to accommodate the protrusion, so that the protrusion can be at least partially embedded in the clearance groove, reducing the space required for the protrusion outside the support member, which helps to reduce the volume of the support member and the gun head.

[0045] The reset member is sleeved on the periphery of the support member and the protrusion, and is used to generate a force for the protrusion to move into the corresponding clearance groove. The reset member in this example can be used to reset the protrusion so that the protrusion can have a tendency to reset into the clearance groove.

[0046] The main body also includes:

[0047] An outer sleeve is connected between the support and the support member, a through hole connected to the through hole is opened in the outer sleeve, and the second driving device is used to drive the nail gun to sequentially penetrate the through hole, the through hole and the nail body channel along the axial direction of the nail body channel or move out of the through hole, the through hole and the nail body channel; and

[0048] The nail feeding assembly is connected to the outer sleeve, and a nail feeding channel connected to the through hole is provided on the outer sleeve. The nail feeding assembly is used to sequentially feed the nail body to the nail body channel through the nail feeding channel, the through hole and the via hole.

[0049] The outer sleeve in this example can serve as an intermediate connecting piece between the support member and the support, and the outer sleeve can be used to install the support member and the nail feeding assembly; the through hole on the outer sleeve can be used to form a space for the inner sleeve to move, so that the inner sleeve can pass through the outer sleeve and the support, and be used to tighten the nail body.

[0050] The present application also provides a method for using a nail body tightening device, which is used for the nail body tightening device in any of the above examples. The method for using includes:

[0051] Controlling the first driving device to drive the clamping arm to approach and clamp the outer sides of the first part and the second part;

[0052] delivering the nail body to the nail body channel;

[0053] Control the first driving device to not generate force on the clamping arm;

[0054] Pushing the nail body and performing the tightening operation; and

[0055] A moving distance signal of the clamp arm is acquired, and in response to the moving distance signal of the clamp arm, the nail body is output or stopped from being output.

[0056] In this example, by controlling the clamping assembly to clamp the outer sides of the first part and the second part, the clamping assembly can be used to limit the first part and the second part, and then when the nail body is conveyed to the nail body channel, the clamping assembly can be used to fix the gun head to reduce the possibility of the nail body flying out of the gun head when the nail feeding assembly inputs the nail body; by detecting the movement distance signal of the clamp arm, it is convenient to control whether to continue to convey the nail body to the nail body channel, thereby reducing the possibility of the nail body flying out of the nail body channel.

[0057] Among them, in the step of obtaining the moving distance signal of the clamp arm and controlling the nail feeding assembly to output or stop outputting the nail body in response to the moving distance signal of the clamp arm, the moving distance signal of the clamp arm is obtained, and in response to the moving distance signal of the clamp arm when the first part and the second part are separated by force being greater than a first preset value, the nail body is stopped from being fed to the nail body channel.

[0058] In this example, when the moving distance of the clamp arm when it is opened exceeds the first preset value, it can be inferred that the opening of the nail body channel is too large, and then the nail feeding assembly can be controlled to stop feeding the nail body.

[0059] Among them, in the step of obtaining the moving distance signal of the clamping arm and controlling the nail feeding assembly to output or stop outputting the nail body in response to the moving distance signal of the clamping arm, the motion signals of some parts of the first driving device are detected, and the moving distance signal of the clamping arm is obtained according to the motion signal.

[0060] In this example, the movement signals of some components can be used to infer the movement distance signal of the detection clamp arm, thereby improving the convenience and reliability of detection.

[0061] Wherein, after the step of obtaining the moving distance signal of the clamp arm and outputting or stopping outputting the nail body in response to the moving distance signal of the clamp arm, the method of use further includes:

[0062] In response to a movement distance signal of the clamp arm when the first part and the second part are forced to separate being greater than a first preset value, the alarm component is controlled to give an alarm.

[0063] In this example, when the movement range of the clamp arm exceeds the first preset value, it is determined that the opening of the nail body channel between the first part and the second part exceeds the preset opening, and then an alarm is issued so that the staff can know the working status of the nail body tightening device in time.

[0064] The step of controlling the first driving device not to generate force on the clamping arm comprises:

[0065] Detecting whether the nail body reaches the nail body channel; and

[0066] In response to detecting that the nail body reaches the nail body channel, the first driving device is controlled not to generate a force on the clamp arm.

[0067] In this example, by detecting whether a nail body is delivered to the nail body channel, the working state of the first driving device can be controlled in time to facilitate subsequent nail tightening operations.

[0068] The steps of pushing the nail body and tightening the nail body include:

[0069] Controlling the nail gun and the inner sleeve to move toward the gun head; and

[0070] In response to the inner sleeve being connected to the nail body, the nail gun is controlled to generate torque on the inner sleeve to drive the inner sleeve to rotate.

[0071] In this example, the nail gun and the inner sleeve are controlled to move toward the gun head so that the inner sleeve can act on the nail body. When the nail gun drives the inner sleeve to rotate, the inner sleeve can act on the nail body to tighten the nail body. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" in the description of this application should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0095] In this application, the word "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0096] During the installation and maintenance of devices such as batteries, in order to facilitate the automated tightening and fixing of the nail body, a nail gun can be used to tighten the nail body. The nail gun usually has a gun head, and the gun head has a nail body channel. After the nail body is transported to the nail body channel of the gun head according to a preset trajectory, the nail body can be tightened on the target device by rotating the nail body.

[0097] In some technologies, the nail body can be delivered to the nail body channel by a nail feeding device, and the gun head can be used to produce a certain limiting effect on the nail body. After the nail body enters the nail body channel, the tightening device and the nail body are connected to each other and drive the nail body to rotate, so that the nail body can be tightened on the target position of the target device; in the process of tightening the nail body, the nail body will produce a certain extrusion on the gun head, causing the gun head to produce a certain deformation, and the opening of the nail body channel of the gun head will increase to a certain extent. When the instantaneous force applied to the gun head is too large, the opening of the gun head may exceed the preset range. If the gun head cannot return to the position that can limit the nail body, the nail body subsequently output by the nail feeding device will easily fly out of the gun head. Taking the use of high-pressure pneumatic nail feeding as an example, in the process of blowing the nail body through high-pressure gas, the high-pressure gas acts on the nail body channel, the gun head is impacted by the high-pressure gas, and the opening of the nail body channel of the gun head increases. When the opening of the nail body channel expands beyond the preset range, the gun head cannot limit the nail body. When the nail body is subsequently input into the gun head, the nail body that has entered the nail body channel will easily fly out of the gun head.

[0098] In response to the above-mentioned problems, the example of the present application proposes a nail body tightening device, comprising a main body, a gun head, a clamping assembly, a detection assembly and a nail feeding assembly, wherein the gun head comprises a first part and a second part, a nail body channel for outputting the nail body is formed between the first part and the second part; the first part and the second part are respectively movably connected to the main body; the clamping assembly comprises a first driving device and a clamping arm, and the clamping arm is movably arranged on the outside of the first part and the second part; the first driving device is connected to the main body, and the first driving device drives the clamping arm to approach and clamp the outside of the first part and the second part; the clamping arm drives some parts of the first driving device to move when the first part and the second part are separated by force; the detection assembly is connected to the main body or the first driving device, and the detection assembly is used to obtain a moving distance signal of the clamping arm; the nail feeding assembly is electrically connected to the detection assembly, and is used to transport the nail body to the nail body channel, and the nail feeding assembly is used to output or stop outputting the nail body according to the moving distance signal. The gun head in this example is composed of a first part and a second part spliced ​​together, which can easily form a nail body channel, facilitate the transportation of the nail body, and enable the gun head to play a certain limiting role on the nail body; by using a clamping component to clamp the outside of the first part and the second part, the clamping component can limit the first part and the second part, and then the first part and the second part can be conveniently locked by the clamping component, so that the first part and the second part can maintain a preset state, reducing the problem of excessive opening of the nail body channel caused by the first part and the second part being far away from each other, thereby reducing the possibility of the nail body flying out of the nail body channel; by using a detection component to detect the moving distance signal of the clamp arm, the opening of the nail body channel can be indirectly obtained through the moving distance signal of the clamp arm, and it can be determined whether the nail feeding component continues to output the nail body according to the opening of the nail body channel, so as to further reduce the possibility of the nail body flying out of the nail body channel.

For example, if the first part 111 and the second part 112 are both provided with grooves on the surfaces facing each other, the grooves on the first part 111 and the second part 112 can enclose to form the nail body channel 115. Optionally, the first portion 111 and the second portion 112 may have different shapes. For example, the cross section of the first portion 111 may be semicircular, and the cross section of the second portion 112 may be trapezoidal or rectangular.

[0102] The first part 111 and the second part 112 are respectively movably connected to the main body 10, which means that the first part 111 and the second part 112 can move along a preset trajectory relative to the main body 10. When the first part 111 and the second part 112 move relative to each other, the opening of the nail body channel 115 formed between the first part 111 and the second part 112 will also change synchronously. When the nail body enters the nail body channel 115, the nail body channel 115 can maintain the current opening state, so that the first part 111 and the second part 112 can limit the nail body, and the nail body maintains the current posture in the nail body channel 115. When the nail body is driven to rotate, the nail body is moved along the nail body channel 115 by the external force. During the movement of the nail body, the nail body can squeeze the first part 111 and the second part 112, so that the first part 111 and the second part 112 move relative to the main body 10, and the opening of the nail body channel 115 also changes synchronously, so that the nail body can move from the inside of the nail body channel 115 to the outside, and then the nail body can be moved out of the nail body channel 115.

[0103] In this example, the first part 111 and the second part 112 can be connected in a rotatable, slidable, or a combination of rotatable and slidable manner relative to the main body 10. Optionally, the first part 111 and the second part 112 can be rotatably connected to the main body 10, so that the first part 111 and the second part 112 can rotate relative to the main body 10, and when the first part 111 and the second part 112 rotate relative to the main body 10, the opening of the nail body channel 115 between the first part 111 and the second part 112 can gradually change. Taking the first part 111 and the second part 112 as an example, the first part 111 and the second part 112 can rotate relative to the main body 10, so that the first part 111 and the second part 112 can be relatively separated, and the opening of the nail body channel 115 at one end away from the rotation center of the first part 111 and the second part 112 can gradually increase. In this example, the first part 111 and the second part 112 can move relative to the main body 10 respectively. When the first part 111 and the second part 112 are squeezed by the nail body, the first part 111 and the second part 112 can move synchronously, so that the first part 111 and the second part 112 can be forced to move synchronously, thereby reducing deformation caused by uneven force on one side.

[0104] In the example of the present application, the gun head 11 is formed by combining the first part 111 and the second part 112. When the nail body enters the nail body channel 115, the first part 111 and the second part 112 can be used to limit the nail body so that the nail body can maintain a preset state in the nail body channel 115, which is convenient for subsequent tightening of the nail body.

[0105] The nail body channel 115 may be a hollow channel that runs through the length direction of the gun head 11 , and the nail body may move along the nail body channel 115 .

[0106] The clamping assembly 12 is disposed on the outside of the gun head 11, and the clamping assembly 12 can be used to cooperate with the gun head 11 to limit the opening of the nail body channel 115. In the example of the present application, the clamping assembly 12 can be clamped on the outside of the first part 111 and the second part 112, so that the clamping assembly 12 can be used to block the first part 111 and the second part 112 from moving away from each other, thereby allowing the nail body channel 115 to maintain a preset opening. The clamping assembly 12 in this example can be a clamping claw formed by a clamping arm 121, and the clamping arm 121 of the clamping claw can be located on the outside of the first part 111 and the second part 112, so that the clamping arm 121 can be used to form a limiting structure on the outside of the first part 111 and the second part 112 to limit the first part 111 and the second part 112 from moving away from each other. Optionally, the clamping assembly 12 may also be at least partially annular in structure, and the clamping assembly 12 may be sleeved on the outside of the first portion 111 and the second portion 112 , so that the relative displacement of the first portion 111 and the second portion 112 can be limited by the annular clamping assembly 12 .

[0107] In the example of the present application, the clamping assembly 12 is matched with the gun head 11, and the clamping assembly 12 is movably clamped on the outer sides of the first part 111 and the second part 112. Before the nail body is input, the clamping assembly 12 can be clamped on the outer sides of the first part 111 and the second part 112, and the clamping assembly 12 is in a locked state so that the first part 111 and the second part 112 cannot move relative to each other. When the nail body enters the first part 111 and the second part 112, the nail body can be limited by the first part 111 and the second part 112 to keep the nail body in the current state; when the nail body needs to be tightened, the clamping assembly 12 can be in a released state, and the clamping assembly 12 is only subjected to the force of the first part 111 and the second part 112. In the process of rotating the nail body, the nail body will squeeze the first part 111 and the second part 112, so that the first part 111 and the second part 112 tend to move away from each other, reducing the obstruction of the first part 111 and the second part 112 to the nail body, so as to facilitate the removal of the nail body from the nail body channel 115. During the process of inputting the nail body into the nail body channel 115 , since the first part 111 and the second part 112 can be clamped by the clamping assembly 12 , the clamping assembly 12 can limit the opening of the nail body channel 115 and reduce the possibility of the nail body flying out of the gun head 11 .

[0108] In some examples, the movement of the clamping assembly 12 can be controlled by a controller, and the controller can be an integrated circuit or an integrated control device integrated in the nail body tightening device, or a control device that can be used to send and receive control signals and is disposed outside the nail body tightening device. Optionally, the clamping assembly 12 can limit the first part 111 and the second part 112 of the gun head 11 by controlling the locking or loosening of the clamping assembly 12. The controller can be an integrated circuit board or other structure that can perform an integrated control function. The controller can be used to control the clamping assembly 12 to be in a clamping state. When the clamping assembly 12 is in the clamping state, the clamping assembly 12 clamps the first part 111 and the second part 112 so that the first part 111 and the second part 112 are locked with each other. At this time, when the nail body enters the nail body channel 115, the movement of the nail body can be restricted by the first part 111 and the second part 112 so that the nail body can maintain a preset posture in the nail body channel 115; the controller can also be used to control the clamping assembly 12 to be in a relaxed state. The clamping assembly 12 does not block the first part 111 and the second part 112. When the first part 111 and the second part 112 move away from each other, the first part 111 and the second part 112 can drive the clamping assembly 12 to move synchronously, thereby increasing the opening of the nail body channel 115 so that the nail body can be output from the nail body channel 115. Optionally, the first part 111 and the second part 112 can push the clamping assembly 12. When the movement range of the clamping assembly 12 relative to the first part 111 and the second part 112 exceeds the preset range, it means that the movement range of the first part 111 and the second part 112 exceeds the preset value. At this time, the opening of the nail body channel 115 may exceed the preset opening. The first part 111 and the second part 112 cannot limit the nail body, and the nail body may fly out of the gun head 11. At this time, an alarm can be selected.

[0109] Please refer to Figure 4 , Figure 5 , Figure 6 as well as Figure 7 The first driving device 122 can be used as a driving member of the clamp arm 121. The first driving device 122 can be used to drive the clamp arm 121 to move so that the clamp arm 121 can be close to or away from the gun head 11. When the clamp arm 121 is close to the gun head 11, the clamp arm 121 can be clamped on the outside of the first part 111 and the second part 112 to limit the range of outward movement of the first part 111 and the second part 112; when the clamp arm 121 is away from the gun head 11, the distance between the clamp arm 121 and the gun head 11 increases, the clamp arm 121 can be in an open state, and the restriction of the clamp arm 121 on the first part 111 and the second part 112 is relatively reduced. The first driving device 122 in the example of the present application can be a cylinder, a motor or other equipment that can be used to drive the clamp arm 121 to reciprocate along a preset trajectory.

[0110] In this example, the clamp arm 121 cooperates with the first driving device 122 so that the clamp arm 121 can correspond to the first part 111 and the second part 112 , and the clamp arm 121 is used to limit the movement of the first part 111 and the second part 112 .

[0111] The first driving device 122 has some parts, and the some parts can be connected to the clamp arm 121. The first driving device 122 can drive the some parts to move along the first direction 5a, so that the clamp arm 121 is close to and clamped on the outside of the first part 111 and the second part 112. The some parts can be used as the intermediate connecting parts between the clamp arm 121 and the first driving device 122. In this example, the some parts can be long linear structures, and the some parts can also be irregular shapes or connecting rod groups. The some parts are used to move along the first direction 5a under the drive of the first driving device 122. When the some parts move along the first direction 5a, the clamp arm 121 moves synchronously, so that the clamp arm 121 can act on the first part 111 and the second part 112 respectively, and then the first part 111 and the second part 112 can be close to each other, so that the opening of the nail body channel 115 can be reduced. In this example, the first direction 5a can be a straight line direction, that is, the some parts can move along the straight line direction. Optionally, the first direction 5a can also be a curve direction or a direction combining a curve and a straight line. The first driving device 122 can generate a force to drive and lock the partial components in the first direction 5a, so that when the partial components move along the first direction 5a, the clamp arm 121 can be closed, and the first driving device 122 and the partial components can also be used to limit the opening of the clamp arm 121, so that the clamp arm 121 can be used to lock the outside of the first part 111 and the second part 112. When the first driving device 122 does not generate a force on the partial components, the partial components can be in a relaxed state, and at this time, the partial components can move in the first direction 5a or the opposite direction of the first direction 5a. Optionally, the first driving device 122, the partial components and the two clamp arms 121 can be combined to form one of a slider-type parallel opening and closing cylinder, a synchronous rotating parallel opening and closing mechanism, a connecting rod structure synchronous opening and closing claw structure or a gear rack synchronous opening and closing claw structure.

[0112] When the first part 111 and the second part 112 are separated, causing the opening of the nail body channel 115 to increase, the first part 111 and the second part 112 act on the clamp arm 121, so that the clamp arm 121 can be forced to separate, and the clamp arm 121 can drive some components to move in the opposite direction of the first direction 5a. The clamp arm 121 and some components are connected and fixed to each other, so that some components can form a linkage with the clamp arm 121. In this example, when the clamp arm 121 is opened, the clamp arm 121 can drive some components to move in the opposite direction of the first direction 5a.

[0113] The detection component 13 is used to detect the moving distance of the clamp arm 121. Optionally, the detection component 13 can be used to directly detect the moving distance of a specific part on the clamp arm 121. The detection component 13 can also be used to detect the moving distance of some components in the opposite direction of the first direction 5a. By detecting the moving distance of some components in the opposite direction of the first direction 5a, the moving distance signal when the clamp arm 121 is opened can be indirectly obtained. The detection component 13 in this example can be used to detect the moving distance of some components or specific parts on the clamp arm 121, and then obtain the overall moving distance of some components. Optionally, the detection component 13 can be at least one of a potentiometer displacement sensor, an inductive displacement sensor, a synchro, a capacitive displacement sensor, an eddy current displacement sensor, and a Hall displacement sensor. The detection component 13 in the example of this application can be one of the above detection devices, or a combination of multiple detection devices. Taking the Hall displacement sensor as an example, in this example, a magnetic ring 132 can be set on some components, and the position of the magnetic ring 132 is detected by the Hall element 131, so as to determine the moving distance of some components.

[0114] The nail delivery assembly 200 is used to deliver the nail body to the nail body channel 115. The nail delivery assembly 200 in the present application example can be a pneumatic nail delivery device. The nail delivery assembly 200 is connected to the nail body channel 115, and the nail delivery assembly 200 is used to deliver the nail body to the nail body channel 115.

[0115] The nail feeding component 200 is electrically connected to the detection component 13, which means that the nail feeding component 200 and the detection component 13 can transmit electrical signals. In the example of the present application, the nail feeding component 200 and the detection component 13 can directly transmit electrical signals, or indirectly transmit electrical signals. Optionally, the nail feeding component 200 and the detection component 13 can transmit electrical signals through the controller in any of the above examples.

[0116] The nail feeding assembly 200 is used to output or stop outputting the nail body according to the moving distance signal, which means that the nail feeding assembly 200 can determine whether to continue outputting the nail body according to the moving distance signal of the clamping arm 121.

[0117] In the example of the present application, it can be assumed that when the first part 111 and the second part 112 are close to each other, so that the nail body channel 115 is at the minimum opening, the moving distance of the clamp arm 121 is the initial distance. When the first part 111 and the second part 112 are away from each other, the clamp arm 121 is subjected to the force of the first part 111 and the second part 112, so that the clamp arm 121 is opened, and the opening of the nail body channel 115 gradually increases, and the moving distance of the clamp arm 121 gradually increases. In this example, it can be estimated based on the moving distance signal of the clamp arm 121 whether the current moving range of the first part 111 and the second part 112 exceeds the preset range, and whether the opening of the nail body channel 115 exceeds the preset opening. When the opening of the nail body channel 115 exceeds the preset opening, the nail feeding assembly 200 can stop outputting the nail body. When the opening of the nail body channel 115 does not exceed the preset opening, the nail feeding operation can be repeated. Since the nail body may exert a force on the first part 111 and the second part 112 during the nail body output process, when the first part 111 and the second part 112 are opened by the force to a degree exceeding the preset degree, when the nail body continues to be output to the nail body channel 115, the nail body may fly out of the nail body channel 115 between the first part 111 and the second part 112. In this example, the degree of opening of the nail body channel 115 can be calculated based on the moving distance signal of the clamp arm 121, and then it can be determined whether it is necessary to continue to output the nail body, so as to reduce the possibility of the nail body flying out of the gun head 11.

[0118] In some examples, the nail feeding assembly 200 is used to stop feeding the nail body to the nail body channel 115 when the moving distance signal of the clamp arm 121 when the first part 111 and the second part 112 are separated by force is greater than the first preset value. When the moving distance signal reaches the first preset value, it means that the moving range of the first part 111 and the second part 112 exceeds the preset range, and the opening of the corresponding nail body channel 115 exceeds the preset opening. At this time, the gun head 11 may be in an abnormally open state. At this time, when the nail body is input into the nail body channel 115, the first part 111 and the second part 112 cannot limit the nail body, and the nail body may fly out of the gun head 11. In this example, the moving distance signal of the clamp arm 121 is detected by the detection assembly 13. On the one hand, it can reduce the possibility of the nail body flying out of the gun head 11 when the opening of the nail body channel 115 of the gun head 11 is too large, and on the other hand, it can facilitate the monitoring of the nail output situation, which can help improve the reliability of the nail body tightening device.

[0119] See also Figure 7 In some examples, the nail gun 100 also includes an alarm component 14, which is electrically connected to the detection component 13. The alarm component 14 is used to receive a moving distance signal and to issue an alarm when the detection component 13 detects that the moving distance signal of the clamp arm 121 reaches a first preset value when the first part 111 and the second part 112 are forced to separate.

[0120] The alarm component 14 can be used to perform at least one of the alarm modes of sound, light and electricity alarm. The alarm component 14 is electrically connected to the detection component 13, which means that the alarm component 14 can transmit signals with the detection component 13. In this example, the moving distance of the clamp arm 121 is detected by the detection component 13. When the moving distance signal of the clamp arm 121 reaches the first preset value, it means that the moving range of some components exceeds the preset range, and the opening of the corresponding nail body channel 115 exceeds the preset opening. At this time, the gun head 11 may be in an abnormally open state. At this time, when the nail body is input into the nail body channel 115, the first part 111 and the second part 112 cannot play a limiting role on the nail body, and the nail body may fly out of the gun head 11. In this example, when the moving distance signal reaches the first preset value, the alarm component 14 is controlled to alarm, which can be used to remind the user of the current working state of the gun head 11, so as to reduce the possibility of the nail body flying out of the gun head 11 due to the excessive opening of the nail body channel 115. The alarm component 14 in this example can be integrated into the screw tightening equipment, and the alarm component 14 can also be remotely set on a control system such as a host computer.

[0121] In some examples, there are two clamping arms 121, and the first driving device 122 is respectively connected to the two clamping arms 121. The first driving device 122 is used to drive the two clamping arms 121 to approach each other and clamp the outside of the first part 111 and the second part 112 respectively. When the first part 111 and the second part 112 are separated by force, the two clamping arms 121 drive some parts of the first driving device 122 to move. The two clamp arms 121 can be respectively arranged corresponding to the first part 111 and the second part 112, and the two clamp arms 121 can be respectively arranged on the side of the first part 111 and the second part 112 away from the nail body channel 115, so that the two clamp arms 121 can be respectively used to limit the first part 111 and the second part 112 from moving away from each other. In this example, the two clamp arms 121 can be in the shape of a long strip as a whole, and the inner surfaces of the two clamp arms 121 can be adapted to the shape of the outer surfaces of the corresponding first part 111 and the second part 112. Taking the first part 111 and the second part 112 as an example of docking to form a cylindrical structure, the inner surfaces of the two clamp arms 121 can be in an arc shape to increase the contact area between the two clamp arms 121 and the corresponding first part 111 and the second part 112. For the convenience of description, the following examples of this application are described by taking the number of clamp arms 121 as two, and the two clamp arms 121 clamping the outer sides of the first part 111 and the second part 112 respectively.

[0122] In some examples, the first driving device 122 is a parallel cylinder, some components of the first driving device 122 are piston rods of the parallel cylinder, and some components are connected to the clamping arm 121. When the first driving device 122 drives some components to move along the first direction 5a, the clamping arm 121 clamps the outside of the first part 111 and the second part 112. When the first part 111 and the second part 112 are separated by force, the clamping arm 121 drives some components to move in the opposite direction of the first direction 5a.

[0123] The first driving device 122 may be a parallel cylinder, and the partial component may be a piston rod. The first driving device 122 may be used to drive the partial component to reciprocate along the length direction. In this example, by using the cylinder and the piston rod to cooperate, the partial component may be made to move in a straight line, thereby facilitating the control of the movement trajectory and stroke of the partial component, thereby improving the control accuracy of the partial component and the stability of the movement trajectory.

[0124] In some examples, the two clamp arms 121 are arranged parallel to each other. In this example, the two clamp arms 121 can form a parallel clamp structure. When the two clamp arms 121 approach each other, the two clamp arms 121 can clamp on the outside of the first part 111 and the second part 112. When the first part 111 and the second part 112 are opened by the action of the nail body, the first part 111 and the second part 112 can drive the two clamp arms 121 away from each other, and the two clamp arms 121 can drive some components to move in a straight line.

[0125] See also Figure 2 In some examples, the clamping assembly 12 further includes a guide rail, which is connected to the first driving device 122, and the two clamping arms 121 are respectively slidably connected to the guide rail.

[0126] The guide rail in this example can be a linear guide rail, and the two clamping arms 121 can move closer to or farther from each other along a straight line. Optionally, the guide rail can also adopt other motion trajectories. The guide rail is connected to the first drive device 122 so that the guide rail can slide and cooperate with the two clamping arms 121 nearby. On the one hand, the moving trajectory of the two clamping arms 121 can be limited by the guide rail, and on the other hand, the position of the two clamping arms 121 can be limited by the guide rail to improve the stability of the two clamping arms 121. Optionally, the guide rail can be a forward and reverse screw connected to the first drive device 122, wherein the two clamping arms 121 can cooperate with the forward and reverse threads of the forward and reverse screw respectively, so that the two clamping arms 121 can move in the opposite direction.

[0127] In some examples, the detection component 13 is connected to some components of the first drive device 122, and the detection component 13 is used to detect the motion signal of some components, so as to obtain the moving distance signal of the clamp arm 121. In this example, the detection component 13 can detect the motion signal of some components to indirectly obtain the moving distance signal of the clamp arm 121. Since the moving trajectory of some components is relatively certain and some components are connected to the first drive device 122, the detection component 13 can be integrated on the first drive device 122 to make full use of the space on the nail body tightening device and reduce the interference of the detection component 13 on the gun head 11.

[0128] In some examples, the first drive device 122 has a solenoid valve 123. When the solenoid valve 123 is turned on, the first drive device 122 can drive the clamping arm 121 to approach and clamp the outside of the first part 111 and the second part 112. When the solenoid valve 123 is closed, the first drive device 122 does not exert force on the clamping arm 121.

[0129] The first driving device 122 has an electromagnetic valve 123. When the electromagnetic valve 123 is turned on, the first driving device 122 can drive some components to move along the first direction 5a, so as to drive the two clamping arms 121 to approach each other and clamp on the outside of the first part 111 and the second part 112, thereby clamping the gun head 11; when the electromagnetic valve 123 is closed, the first driving device 122 can be closed or on standby, and the first driving device 122 does not generate driving force on some components, so that some components are in a relaxed state. The first driving device 122 no longer generates force on some components, so that some components are in a relaxed state. At this time, some components can move in the opposite direction of the first direction 5a. When the clamping arm 121 is subjected to external force, the clamping arm 121 can synchronously drive some components to move. At this time, the two clamping arms 121 do not have a locking effect on the first part 111 and the second part 112, so that the nail body can be smoothly output through the nail body channel 115.

[0130] In some examples, the nail body tightening device also includes a nail body detection component 16, which is connected to the gun head 11 and is used to detect whether the nail body output by the nail feeding component 200 has reached the nail body channel 115; the solenoid valve 123 is electrically connected to the nail body detection component 16, and the solenoid valve 123 is used to close when the nail body detection component 16 detects that the nail body output by the nail feeding component 200 has reached the nail body channel 115.

[0131] The nail body detection component 16 can be used to detect whether the nail body output by the nail feeding component 200 reaches the nail body channel 115, so as to determine whether to close the solenoid valve 123. The nail body detection component 16 in this example can be a contact detection or a non-contact detection. When it is detected that the nail body reaches the nail body channel 115, the solenoid valve 123 can be in a closed state, so that some components are no longer subject to the limiting effect of the first drive device 122. At this time, the first part 111 and the second part 112 limit the nail body in the nail body channel 115. At the same time, the first part 111 and the second part 112 are no longer subject to the clamping force of the two clamping arms 121; when the nail body is pushed to move along the nail body channel 115, the nail body can generate a force on the first part 111 and the second part 112, and the two clamping arms 121 can be relatively separated under the action of the first part 111 and the second part 112, so that the two clamping arms 121 do not restrict the first part 111 and the second part 112, so as to facilitate the removal of the nail body from the nail body channel 115.

[0132] Please refer to Figure 1 , Figure 2 as well as Figure 3 In some examples, the main body 10 includes a support 106, a nail gun 101, an inner sleeve 104 and a second driving device 105, and the nail gun 101 is connected to the support 106; the nail gun 101 is drivingly connected to the inner sleeve 104 to provide a torque to drive the inner sleeve 104 to rotate relative to the gun head 11, and the nail body channel 115 is open at one end facing the nail gun 101; the second driving device 105 is drivingly connected to the nail gun 101, and the second driving device 105 is used to drive the nail gun 101 to penetrate the nail body channel 115 or move out of the nail body channel 115 along the axial direction of the nail body channel 115.

[0133] The support 106 can be used to be connected to an external device such as a robot. Optionally, the support 106 can be in the form of a long strip, and the length direction of the support 106 can be arranged parallel to the length direction of the gun head 11 .

[0134] The nail gun 101 is connected to the support 106, and the nail gun 101 can be used to generate torque to rotate the nut, thereby tightening the nut on the preset device. The nail gun 101 in this example can be a motor or other structure that can be used to drive the nail body to rotate.

[0135] Please refer to Figure 8, the inner sleeve 104 is used to dock with the nail body, and the nail gun 101 is drivingly connected to the inner sleeve 104, so that the nail gun 101 can generate torque on the inner sleeve 104, so that the inner sleeve 104 can rotate along a preset direction. In this example, the end of the inner sleeve 104 away from the nail gun 101 can be adapted to the nail body, so that when the inner sleeve 104 is docked on the nail body, the inner sleeve 104 can drive the nail body to rotate. The end of the nail body channel 115 facing the nail gun 101 is open, which means that the end of the nail body channel 115 facing the nail gun 101 is open, and the inner sleeve 104 can be inserted into the nail body channel 115.

[0136] The second driving device 105 is used to drive the nail gun 101 to move toward the gun head 11, so that the inner sleeve 104 can move toward the nail body, and then the inner sleeve 104 can dock with the nail body. The second driving device 105 in this example can be a cylinder or other device that can be used to drive the nail gun 101 to move toward or away from the gun head 11.

[0137] Please refer to Figure 8 In some examples, the main body 10 further includes a reset member 15 , which is connected to the support 106 ; the reset member 15 is also connected to the first portion 111 and the second portion 112 , and is used to generate a force for the first portion 111 and the second portion 112 to fit each other.

[0138] The reset member 15 is connected to the support 106 so that the reset member 15 is fixed at a preset position on the support 106. The reset member 15 is also connected to the first part 111 and the second part 112, which means that the reset member 15 is connected to the first part 111 and the second part 112, and the reset member 15 can generate an elastic force on the first part 111 and the second part 112. The reset member 15 in this example is used to generate a force for the first part 111 and the second part 112 to fit each other. When the first part 111 and the second part 112 fit each other, the nail body channel 115 can be in a minimum opening state. The reset member 15 in this example can generate an elastic compressive force on the first part 111 and the second part 112 so that the first part 111 and the second part 112 have a tendency to fit each other. When the first part 111 and the second part 112 are squeezed open by the nail body, the reset member 15 can be used to reset the first part 111 and the second part 112 so that the first part 111 and the second part 112 can limit the nail body.

[0139] In some examples, the restoring member 15 is annularly sleeved on the outer sides of the first portion 111 and the second portion 112 .

[0140] The reset member 15 can form an elastic limit function on the first part 111 and the second part 112 on the outside of the first part 111 and the second part 112, so that the first part 111 and the second part 112 have a tendency to fit and reset each other. The reset member 15 can be an elastic pad sleeved on the outside of the first part 111 and the second part 112, and the elastic force of the reset member 15 can be changed by changing the material and thickness of the elastic pad.

[0141] Please refer to Fig. 9 , Fig.10 as well as Fig.11 In some examples, the main body 10 also includes a support member 102, which is connected between the support 106 and the gun head 11. A through hole 1021 connected to the nail body channel 115 is opened on the support member 102. The second driving device 105 is used to drive the nail gun 101 to pass through the through hole 1021 and the nail body channel 115 in sequence along the axial direction of the nail body channel 115 or move out of the nail body channel 115; the first part 111 and the second part 112 are respectively rotatably connected to the support member 102.

[0142] The support member 102 can be used as an intermediate connecting member between the support 106 and the gun head 11. The support member 102 is connected to one end of the support 106 away from the nail gun 101, and the gun head 11 is connected to the support member 102. The support member 102 in this example can be generally in a hollow cylindrical structure, and the through hole 1021 is a through hole that penetrates the support member 102. The through hole 1021 in this example can be coaxially arranged with the nail body channel 115. When the nail body needs to be tightened, the inner sleeve 104 can pass through the through hole 1021 and enter the nail body channel 115, so that the inner sleeve 104 can dock with the nail body in the nail body channel 115, and the nail gun 101 drives the inner sleeve 104 to rotate, thereby driving the nail body to be tightened on the target device. The second driving device 105 can also drive the nail gun 101 to move away from the gun head 11, so that the inner sleeve 104 can be moved out of the nail body channel 115.

[0143] The first part 111 and the second part 112 are rotatably connected to the support 102 so that the first part 111 and the second part 112 can be moved relative to the main body 10. In this example, a rotating shaft 114 can be set on the support 102, and the first part 111 and the second part 112 can be rotatably connected to the corresponding rotating shaft 114 on the support 102 respectively.

[0144] Please refer to Fig. 9 , Fig.10 as well as Fig.11In some examples, a locking groove 1022 is respectively provided on the side walls of the support member 102 corresponding to the first part 111 and the second part 112; a protrusion 113 is respectively provided on the end of the first part 111 and the second part 112 facing the main body 10, and a rotating shaft 114 is provided on the end of the protrusion 113 close to the nail gun 101, and the rotating shaft 114 is rotatably embedded in the corresponding locking groove 1022.

[0145] The positioning groove 1022 may be a recessed groove formed on the outer wall of the support member 102. In this example, the positioning grooves 1022 are respectively formed at the positions corresponding to the first portion 111 and the second portion 112.

[0146] Please refer to Fig.12 , Fig.13 , Fig.14 as well as Fig.15 The first part 111 and the second part 112 are respectively provided with a protrusion 113, which can be a convex block structure provided on the first part 111 and the second part 112 facing the nail gun 101. The protrusion 113 is provided with a rotating shaft 114, which is rotatably embedded in the corresponding clamping groove 1022, and the clamping groove 1022 can limit the movement of the rotating shaft 114 along the axial direction of the support member 102 to reduce the possibility of the first part 111 and the second part 112 falling off along the axial direction of the support member 102; in this example, the rotating shaft 114 can be used as the rotation center of the first part 111 and the second part 112. When the first part 111 and the second part 112 rotate relative to the support member 102, the rotating shaft 114 can always cooperate with the corresponding clamping groove 1022 to limit the movement of the first part 111 and the second part 112.

[0147] In some examples, a clearance groove 1023 is respectively provided on the side walls of the support member 102 corresponding to the first part 111 and the second part 112, and the clearance groove 1023 passes through the corresponding locking groove 1022 to the end of the support member 102 away from the nail gun 101; the protrusions 113 of the first part 111 and the second part 112 are respectively rotatably embedded in the corresponding clearance groove 1023.

[0148] The position of the give way groove 1023 corresponds to the locking groove 1022, the give way groove 1023 is connected to the locking groove 1022, and the give way groove 1023 extends to the end of the support member 102 away from the nail gun 101, so that the give way groove 1023 can be used to accommodate the protrusion 113, and the protrusion 113 can be at least partially accommodated on the inner side of the give way groove 1023. On the one hand, the space on the support member 102 can be fully utilized. On the other hand, the give way groove 1023 can be used to limit the movement of the protrusion 113 along the circumferential direction of the support member 102. On the other hand, the protruding distance of the protrusion 113 on the outer peripheral surface of the support member 102 can be reduced, which helps to reduce the volume of the support member 102 and the protrusion 113 and fully utilize the space.

[0149] In some examples, the reset member 15 is sleeved on the periphery of the support member 102 and the protrusion 113, and the reset member 15 is used to generate a force on the protrusion 113 to move into the corresponding give way groove 1023. The reset member 15 is used to generate an elastic force on the protrusion 113 at the periphery of the protrusion 113, so that the protrusion 113 can have a tendency to move into the give way groove 1023. In this example, by making the reset member 15 cooperate with the protrusion 113, the protrusion 113 is reset by the reset member 15, so that the first part 111 and the second part 112 have a tendency to fit each other. Since the reset member 15 and the protrusion 113 cooperate with each other, the reset member 15 can be easily installed, so that the reset member 15 can be installed close to the support member 102 and the end of the gun head 11 close to the support member 102, so that the reset member 15 has the function of resetting the gun head 11, and the space occupied by the reset member 15 is relatively smaller. Optionally, in this example, a groove may be provided on the outer surface of the protrusion 113 , and the reset member 15 may be snapped into the corresponding groove to limit the reset member 15 and reduce the possibility of displacement of the reset member 15 .

[0150] In some examples, the main body 10 also includes an outer sleeve 103, which is connected between the support 106 and the support member 102. A through hole connected to the through hole 1021 is opened in the outer sleeve 103, and the second driving device 105 is used to drive the nail gun 101 to penetrate the through hole, the through hole 1021 and the nail body channel 115 in sequence along the axial direction of the nail body channel 115 or move out from the through hole, the through hole 1021 and the nail body channel 115; the nail feeding assembly 200 is connected to the outer sleeve 103, and a nail feeding channel 1031 connected to the through hole is also opened on the outer sleeve 103. The nail feeding assembly 200 is used to convey the nail body to the nail body channel 115 through the nail feeding channel 1031, the through hole and the through hole 1021 in sequence.

[0151] One end of the outer sleeve 103 is connected to the support 106 so that the outer sleeve 103 is fixed at a preset position on the support 106, and the other end of the outer sleeve 103 is connected to the support 102 so that the support 102 can be aligned with the nail gun 101. The outer sleeve 103 in this example can be a hollow cylindrical structure, and a through hole is provided in the outer sleeve 103, and the through hole can be coaxially arranged with the nail body channel 115. The inner sleeve 104 can be arranged corresponding to the position of the through hole of the outer sleeve 103, and the inner sleeve 104 can pass through the through hole and dock with the nail body, and the inner sleeve 104 is driven to rotate by the nail gun 101 to drive the nail body to rotate.

[0152] The outer sleeve 103 is also provided with a nail delivery channel 1031, which is connected to the through hole. The nail delivery channel 1031 can be used to connect the nail delivery assembly 200. The nail delivery channel 1031 is connected to the through hole, and the nail body can enter the nail body channel 115 through the nail delivery channel 1031, the through hole, and the through hole 1021 in sequence.

[0153] Please refer to Fig.16 The present application also proposes an example of a method for using the nail body tightening device in any of the above examples, and the method for using the nail body tightening device includes:

[0154] S100 : controlling the first driving device 122 to drive the clamping arm 121 to approach and clamp the outer sides of the first portion 111 and the second portion 112 .

[0155] The clamping assembly 12 can be used to clamp and limit the gun head 11 formed by the first part 111 and the second part 112 to limit the opening of the nail body channel 115 between the first part 111 and the second part 112. The first part 111 and the second part 112 can be used to limit the nail body. The opening of the nail body channel 115 in the example of the present application can be adapted to the size of the nail body. When the first part 111 and the second part 112 are close to each other, the opening of the nail body channel 115 is reduced. At this time, the nail body enters the nail body channel 115. The nail body can be limited by the first part 111 and the second part 112 so that the nail body cannot move out of the nail body channel 115. The nail body can be in a preset angle or posture in the nail body channel 115. The first driving device 122 is used to drive the clamp arm 121 to move, so that the clamp arm 121 can limit the first part 111 and the second part 112 on the outside of the first part 111 and the second part 112, thereby limiting the movement of the first part 111 and the second part 112.

[0156] S200 : delivering the nail body to the nail body channel 115 .

[0157] The nail body can be driven to move into the nail body channel 115 by the nail feeding assembly 200, and the nail feeding assembly 200 in this example can be a pneumatic nail feeding device. In this application example, a nail feeding channel 1031 for connecting the nail feeding assembly 200 can be provided on the main body 10, so that the nail body output by the nail feeding assembly 200 can enter the nail body channel 115 via the nail feeding channel 1031. Optionally, the main body 10 may include the support 106, the outer sleeve 103, the inner sleeve 104, the second driving device 105 and the nail gun 101 in any of the above examples, and the nail feeding channel 1031 can be provided on the outer sleeve 103.

[0158] S300 : controlling the first driving device 122 to not generate force on the clamping arm 121 .

[0159] The clamping assembly 12 includes a clamping arm 121. When the first driving device 122 does not exert force on the clamping arm 121, the clamping arm 121 can move synchronously with the gun head 11. When the first part 111 and the second part 112 of the gun head 11 move in opposite directions to increase the opening of the nail body channel 115, the first part 111 and the second part 112 generate thrust on the clamping arm 121, and the clamping arm 121 can drive some parts of the first driving device 122 to move. When the first part 111 and the second part 112 are squeezed by the nail body, the first part 111 and the second part 112 can drive the clamping arm 121 to move synchronously. In the example of the present application, the solenoid valve 123 in any of the above examples can be used to control the working state of the first drive device 122. By controlling the state switching of the solenoid valve 123, when the solenoid valve 123 is turned on, the first drive device 122 can generate a driving force on the clamping arm 121 through some components, so that the clamping arm 121 has a tendency to approach each other, and the clamping arm 121 can approach and clamp the outer sides of the first part 111 and the second part 112, so that the first part 111 and the second part 112 can have a tendency to fit and clamp each other. When the solenoid valve 123 is further switched to make the solenoid valve 123 When the valve 123 is closed, the first drive device 122 no longer exerts a force on some components, and the first drive device 122 and some components are no longer used to limit the movement of the clamp arm 121. When the first part 111 and the second part 112 are subjected to the force and move away from each other, causing the nail body channel 115 to increase, the first part 111 and the second part 112 exert a force on the clamp arm 121, so that the clamp arm 121 can have a tendency to open. At this time, the clamp arm 121 can act on some components of the first drive device 122, so that some components of the first drive device 122 produce synchronous movement.

[0160] S400: Push the nail body and perform a tightening operation.

[0161] Pushing the nail body refers to pushing the nail body to move along a preset trajectory in the nail body channel 115 so that the nail body can move toward the target device. The tightening operation refers to rotating the nail body so that the nail body can be screwed into a preset position on the target device. In this example, the second driving device 105 can be used to drive the nail gun 101 and the inner sleeve 104 to move synchronously. When the inner sleeve 104 and the nail body are docked with each other, the nail gun 101 drives the inner sleeve 104 to rotate, so that the inner sleeve 104 drives the nail body to rotate, and then the nail body is tightened on the target device.

[0162] In this example, after detecting that the nail body output by the nail feeding assembly 200 reaches the nail body channel 115, the solenoid valve 123 can be controlled to close so that the first drive device 122 does not exert a force on the clamping arm 121. When the nail body is pushed, the nail body will squeeze the first part 111 and the second part 112 of the gun head 11, and the first part 111 and the second part 112 will exert a force on the corresponding clamping arm 121, causing the clamping arm 121 to open.

[0163] S500 : Acquire the moving distance signal of the clamp arm 121 , and output or stop outputting the nail body in response to the moving distance signal of the clamp arm 121 .

[0164] When the first part 111 and the second part 112 move away from each other, the first part 111 and the second part 112 act on the clamping arm 121, so that the clamping arm 121 has a tendency to open. At this time, the movement distance signal of the clamping arm 121 can be determined by obtaining the movement distance of a specific part of the clamping arm 121 when the clamping arm 121 opens.

[0165] When the moving distance signal of the clamp arm 121 is obtained, the nail feeding assembly 200 can determine whether to continue to output the nail body according to the moving distance signal. In this example, since the first part 111 and the second part 112 can generate a force on the clamp arm 121, when the distance between the first part 111 and the second part 112 exceeds the preset range, the opening of the nail body channel 115 may exceed the preset opening. At this time, if the above steps S100 and S200 are repeatedly performed to continue to feed the nail body to the nail body channel 115, the first part 111 and the second part 112 may not be able to limit the nail body, and the nail body may fly out of the nail body channel 115. In order to reduce the possibility of the nail body flying out of the nail body channel 115, the nail feeding assembly 200 can be controlled to stop feeding the nail body. When the distance between the first part 111 and the second part 112 does not exceed the preset range, the opening of the nail body channel 115 may not exceed the preset opening, and the first part 111 and the second part 112 may be able to recover. When the above steps S100 and S200 are repeatedly performed, the first part 111 and the second part 112 can limit the nail body. In this example, it is possible to indirectly determine whether the opening of the nail body channel 115 exceeds the preset range by detecting the moving distance signal of the clamp arm 121, and then indirectly determine whether it is necessary to continue to output the nail body to the nail body channel 115, so as to reduce the possibility of the nail body flying out of the gun head 11 and improve the reliability of the nailing device.

[0166] In some examples, in the above step S500, a moving distance signal of the clamp arm 121 is obtained, and in response to the moving distance signal of the clamp arm 121 when the first part 111 and the second part 112 are forced to separate being greater than a first preset value, the delivery of the nail body to the nail body channel 115 is stopped.

[0167] Since the first part 111 and the second part 112 can exert a force on the clamp arm 121, in this example, the detection component 13 can detect the moving distance signal when the clamp arm 121 is opened. When the moving distance signal is greater than the first preset value when the clamp arm 121 is opened, the nail feeding component 200 is controlled to stop conveying the nail body to the nail body channel 115. When the moving distance signal when the clamp arm 121 is opened is the first preset value, the opening of the nail body channel 115 exceeds the preset range. At this time, the first part 111 and the second part 112 cannot limit the nail body.

[0168] The moving distance signal when the clamping arms 121 are separated by force can be detected by directly detecting the moving distance signal of a specific part of the clamping arms 121, for example, the moving distance of the opening part of the clamping arms 121 can be detected, or the moving distance signal when the clamping arms 121 are separated by force can be detected indirectly. The distance between the clamping arms 121 can be indirectly detected by detecting the stroke of the driving mechanism of the clamping arms 121, and the moving distance signal when the clamping arms 121 are separated by force is calculated based on the stroke of the driving mechanism. In this example, the detection component 13 can be used to detect the moving distance signal when the clamping arms 121 are separated by force. Optionally, in this example, the moving distance signal when the clamping arms 121 are separated by force can be indirectly detected by detecting the stroke of some components.

[0169] When the moving distance signal when the clamp arm 121 is forced to separate is greater than the first preset value, it means that the moving distance when the clamp arm 121 is forced to separate exceeds the preset range. At this time, the distance between the first part 111 and the second part 112 of the gun head 11 may exceed the preset distance, and the opening of the nail body channel 115 exceeds the preset opening. When the nail body is input through the nail feeding assembly 200 again, the nail body may fly out of the nail body channel 115; in this example, by controlling the nail feeding assembly 200 to stop feeding the nail body to the nail body channel 115, the possibility of the nail body flying out of the gun head 11 can be reduced, which helps to improve the reliability of the nail body tightening equipment.

[0170] In some examples, in the above step S500, the motion signal of some components of the first driving device 122 is detected, and the moving distance signal of the clamp arm 121 is obtained according to the motion signal. In this example, the distance when the clamp arm 121 is separated by force can be calculated by detecting the stroke of some components, and then the moving distance signal when the clamp arm 121 is separated by force can be obtained, and the relative moving distance between the first part 111 and the second part 112 can be determined according to the moving distance signal when the clamp arm 121 is separated by force, and then the opening of the nail body channel 115 can be determined. In this example, by detecting the stroke of some components, the detection of the displacement of the clamp arm 121 can be converted into the stroke detection of some components, which can simplify the detection method and improve the detection accuracy.

[0171] Please refer to Fig.17 In some examples, after step S500, the method further includes:

[0172] S600: In response to a movement distance signal of the clamping arm 121 when the first part 111 and the second part 112 are forced to separate being greater than a first preset value, the alarm component 14 is controlled to generate an alarm.

[0173] In this example, when the moving distance signal reaches the first preset value, it means that the moving range of some components exceeds the preset range, and the opening of the corresponding nail body channel 115 exceeds the preset opening. At this time, the gun head 11 may be in an abnormally open state. At this time, when the nail body is input into the nail body channel 115, the first part 111 and the second part 112 cannot limit the nail body, and the nail body may fly out of the gun head 11. In this example, when the moving distance signal reaches the first preset value, the alarm component 14 is controlled to alarm, which can be used to remind the user of the current working state of the gun head 11, so as to reduce the possibility of the nail body flying out of the gun head 11 due to the excessive opening of the nail body channel 115. In this example, the alarm component 14 can be a structure that can be used for alarming and is set on the nail body tightening device. The alarm component 14 can also be set on the host computer, and can remind the user of the working state of the nail body tightening device by remote alarm.

[0174] See also Fig.18 In some examples, the above step S300 includes:

[0175] S310: Detect whether the nail body reaches the nail body channel 115.

[0176] When the nail feeding assembly 200 outputs the nail body, the nail body will enter the nail body channel 115 under the action of the nail feeding assembly 200. In this example, whether the nail body reaches the preset position in the nail body channel 115 can be determined by contact or non-contact detection; the contact detection can be pressure detection, gravity detection or other detection methods, and the non-contact detection can be photoelectric detection; optionally, the combination of contact detection and non-contact detection can be used to check whether the nail body reaches the preset position in the nail body channel 115.

[0177] S320 : In response to detecting that the nail body reaches the nail body channel 115 , the first driving device 122 is controlled not to generate a force on the clamping arm 121 .

[0178] When it is detected that the nail body output by the nail feeding assembly 200 reaches the preset position in the nail body channel 115, the first driving device 122 is controlled to work so that the first driving device 122 does not generate a force on the clamp arm 121. In this example, the state of the clamp arm 121 can be controlled by controlling the state of the first driving device 122. When the first driving device 122 does not generate a force on the clamp arm 121, if the clamp arm 121 is subjected to a force from other structures, the clamp arm 121 can generate relative movement. In this example, the above-mentioned solenoid valve 123 can be used to control the working state of the first driving device 122, and then the working state of the clamp arm 121 can be controlled by the first driving device 122. When the nail body is sent into the nail body channel 115, the solenoid valve 123 can be in an open state, and the first driving device 122 drives the clamping arm 121 to clamp on the first part 111 and the second part 112, and the clamping arm 121 can lock the first part 111 and the second part 112; when the nail body is rotated, since the nail body will squeeze the first part 111 and the second part 112, the solenoid valve 123 can be in a closed state. At this time, the clamping arm 121 and some parts are in a free state, and the force generated by the squeezing of the nail body causes the first part 111 and the second part 112 to move, and the clamping arm 121 does not clamp the first part 111 and the second part 112.

[0179] See also Fig.19 In some examples, after the above step S300 and before step S400, the method for using the nail body tightening device further includes the following steps:

[0180] Please refer to Fig.19 In some examples, step S400 includes:

[0181] S410 : Control the nail gun 101 and the inner sleeve 104 to move toward the direction close to the gun head 11 .

[0182] The inner sleeve 104 is connected to the nail gun 101, and the nail gun 101 is used to drive the inner sleeve 104 to move relative to each other. The inner sleeve 104 can be used to cooperate with the nail body so that the inner sleeve 104 can drive the nail body to move synchronously. In this example, the main body 10 can also include a support 106 and a second driving device 105 connected to the support 106, wherein the second driving device 105 is used to drive the nail gun 101 and the inner sleeve 104 to move synchronously so that the nail gun 101 and the inner sleeve 104 can move in a direction close to or away from the gun head 11. When the nail gun 101 and the inner sleeve 104 move in a direction close to the gun head 11, the inner sleeve 104 can match the nail body in the nail body channel 115, and when the nail gun 101 and the inner sleeve 104 move in a direction away from the gun head 11, the inner sleeve 104 can be separated from the nail body, and the inner sleeve 104 can be removed from the nail body channel 115.

[0183] S420: In response to the inner sleeve 104 being connected to the nail body, the nail gun 101 is controlled to generate torque on the inner sleeve 104 to drive the inner sleeve 104 to rotate.

[0184] When the inner sleeve 104 is connected to the nail body, the nail gun 101 can be used to drive the inner sleeve 104 to rotate, so that the inner sleeve 104 can drive the nail body to rotate, and then the nail body can be screwed onto the target device. In this example, when the nail gun 101 generates torque on the inner sleeve 104 to rotate the inner sleeve 104, the second drive device 105 can be used to continuously generate a thrust on the nail gun 101 in the direction of approaching the gun head 11, so that the inner sleeve 104 can maintain a matching state with the nail body. After the nail body is screwed onto the target device, the second drive device 105 can stop generating a thrust on the nail gun 101 in the direction of approaching the gun head 11, so that the inner sleeve 104 no longer generates a force to push the nail body toward the target device; when the inner sleeve 104 needs to be detached from the nail body, the second drive device 105 can generate a thrust on the nail gun 101 in the direction of away from the gun head 11, so that the nail gun 101 and the inner sleeve 104 are away from the nail body.

[0185] In this example, in response to the inner sleeve 104 being connected to the nail body, it means that the inner sleeve 104 and the nail body are adapted to each other so that the inner sleeve 104 can drive the nail body to move synchronously. In this example, whether the inner sleeve 104 is connected to the nail body can be determined by contact detection or non-contact detection. The contact detection can be pressure detection, and the non-contact detection can be infrared detection. Optionally, it can be determined whether the inner sleeve 104 has reached the position connected to the nail body by detecting the movement distance of the inner sleeve 104 in the direction close to the gun head 11.

[0186] See also Figures 1 to 19The example of the present application proposes a nail gun 100, which includes a main body 10, a gun head 11 and a clamping assembly 12, wherein the main body 10 may include a support 106, a nail gun 101, an outer sleeve 103, an inner sleeve 104 and a second driving device 105, the support 106 can be used to connect to an external device, the nail gun 101 and the outer sleeve 103 are respectively connected to the support 106, the inner sleeve 104 is connected to the nail gun 101, and the second driving device 105 is used to drive the nail gun 101 to move relative to the outer sleeve 103. When the nail gun 101 moves relative to the outer sleeve 103, the inner sleeve 104 can synchronously move toward the direction close to the gun head 11. After the inner sleeve 104 moves to the gun head 11 and docks with the nail body, the inner sleeve 104 can be rotated by the nail gun 101 to tighten the nail body on the target device. The clamping assembly 12 can be used to clamp the gun head 11. In this example, the gun head 11 can include a first part 111 and a second part 112. The first part 111 and the second part 112 can enclose a nail body channel 115 for the nail body to move; the first part 111 and the second part 112 are respectively rotatably connected to the outer sleeve 103, so that when the first part 111 and the second part 112 rotate relative to the outer sleeve 103, the opening of the nail body channel 115 can also change synchronously. When the nail body is delivered to the nail body channel 115, the clamping assembly 12 can be used to clamp the first part 111 and the second part 112 to reduce the possibility of the nail body flying out of the gun head 11. In this example, when the nail body is tightened, the nail body will squeeze the first part 111 and the second part 112, so that the first part 111 and the second part 112 have a tendency to rotate relative to the outer sleeve 103, and the opening of the nail body channel 115 will gradually increase. At this time, the clamping assembly 12 can be in a released state, and the first part 111 and the second part 112 can generate pressure on the clamping assembly 12, so that the clamping assembly 12 is deformed. In this example, the clamping assembly 12 can include a first driving device 122 and a clamping claw formed by two clamping arms 121, wherein the first driving device 122 can drive some parts to move, and some parts are used to drive the two clamping arms 121 to move, thereby driving the two clamping arms 121 to move closer to or away from each other. When the clamping assembly 12 is in a released state, the first part 111 and the second part 112 can generate a force on the two clamping arms 121 to make the two clamping arms 121 move away from each other, thereby driving some parts to move synchronously. In this example, whether the opening of the nail body channel 115 exceeds the preset opening can be determined by detecting the moving range of some components. When the opening of the nail body channel 115 exceeds the preset opening, an alarm can be performed to reduce the possibility of the nail body flying out of the gun head 11 when the nail body channel 115 is abnormally opened.
