Description

Technical Field

[0001] This utility model relates to the field of buckle nail guns, and in particular to an electric buckle nail gun. Background Technology

[0002] A snap-on nail gun is a commonly used tool. Its principle is based on a clamping unit that clamps the nail inside the gun, producing a snap ring. However, current snap-on nail guns have a fixed clamping unit opening, meaning they can only produce snap rings of a specific size. This results in poor applicability and flexibility. When users require different sizes of snap rings for different application scenarios, they need to purchase multiple snap-on nail guns, increasing costs. Utility Model Content

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are only used to distinguish different objects and not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. References to "embodiment" herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] The present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 This application provides an electric buckle nail gun, including: an input module, a clamping module, an opening control module, and a housing (not shown).

[0033] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the input module is used to receive the target size of the buckle input by the user. For example, the input module includes a button module and a digital tube module, or includes an LCD screen (not shown). The button module allows the user to input the target size of the buckle by pressing buttons, and the button module includes buttons SW1, SW2, SW3, resistors R70, R72, and R73. The digital tube module can display the currently input target size of the buckle for the user, and the digital tube module includes a digital tube, resistors R60, R61, and R62. The LCD screen allows the user to input and display the target size of the buckle by touch.

[0034] Reference Figure 1 In this embodiment, the clamping module includes a clamping unit and a detection unit. The clamping unit includes a clamping head and a transmission mechanism. The transmission mechanism connects the clamping head and an opening control module. The opening control module can drive the transmission mechanism to change the opening of the clamping head, allowing the clamping head to clamp a buckle of the target size. For example, in some embodiments, when clamping a buckle (a ring-shaped nail) on a load, different openings of the clamping head can clamp buckles of different sizes. Based on the input target buckle size, the opening control module controls the transmission mechanism accordingly, causing the clamping head to be at the corresponding opening. For example, if the input target buckle size is Amm (representing the buckle diameter), the clamping head is controlled to be at the corresponding opening, such as a diameter of Amm, so that the clamping head clamps and holds a buckle of the target size on the load, i.e., clamps and holds a buckle with a diameter of Amm on the load.

[0035] Optionally, the transmission mechanism includes a gear transmission structure or a rod transmission structure, which connects to the clamping head and drives it. For example, in some embodiments, the rod transmission structure may include a ball screw to convert rotational motion into movement of the clamping head. Alternatively, it may include a reduction gearbox, a connecting rod, and a push rod. The reduction gearbox is connected to the opening control module, the connecting rod is connected to the output end of the reduction gearbox, and the push rod is connected to the connecting rod. Driven by the connecting rod, the push rod can move to drive the clamping head, clamping the nails inside the housing to form a retaining ring, thus clamping the load. It should be noted that the focus of this application's embodiments is not on improving the transmission mechanism. The transmission mechanism can also be implemented using existing similar structures, such as those in publications CN117656004A and CN111300342A, which will not be described in detail here.

[0036] Optionally, the detection unit is used to detect the position information of the clamping unit, such as the position information of the clamping head or the position information of the transmission mechanism; the detection unit includes, but is not limited to, a linear potentiometer (including, but not limited to, the DS4301 model), a magnetic encoder (including, but not limited to, the DS4301 model), or at least one Hall sensor.

[0037] In one embodiment, a magnetic encoder can be placed near the head or tail end of the clamping head. The position information of the magnetic encoder is transmitted to the opening control module, allowing the opening control module to know the position of the clamping head and facilitate precise control of the opening of the head or tail end of the clamping head (because when the tail end has a certain opening, the corresponding head end used for clamping also has a corresponding opening). Alternatively, in some embodiments, several Hall sensors can be placed on the path of the push rod. The position of each Hall sensor corresponds to a different opening of the clamping head. Therefore, the opening control module indirectly knows the position of the clamping head through the position information of the Hall sensors.

[0038] In this embodiment, the opening control module is connected to the input module, the clamping unit, and the detection unit. It is used to receive the target size of the buckle input by the user and the position information detected by the detection unit, so as to control the opening of the clamping unit and clamp the buckle to the target size.

[0039] Optionally, the opening control module includes a power supply unit, a control unit, a drive motor, a start button, and a drive circuit. The control unit is connected to the drive motor, input module, start button, detection unit, and drive circuit. The drive circuit is connected to the drive motor. When the user presses the start button, the control unit is triggered to control the drive motor, initiating the clamping ring clamping process. The drive motor is connected to a transmission mechanism, for example, the drive motor is connected to a ball screw via a coupling or to a reduction gearbox, thereby driving the transmission mechanism to move the tail end of the clamp head, thus moving the head end of the clamp head and adjusting the clamp head opening. In some embodiments, an encoder or Hall sensor can be used to determine the number of rotations of the drive motor and obtain the detected position information.

[0040] like Figure 4As shown in the embodiments of this application, the control unit includes one of MCU, FPGA, CPLD, DSP, and ARM, such as MCU (U3). The control unit has a storage subunit that can store the opening degree corresponding to different buckle sizes and the target value corresponding to each opening degree. The target value is, for example, the target magnetic encoder value or the position of the Hall sensor corresponding to each opening degree. Therefore, after receiving the buckle target size, the corresponding target value can be determined, and then the drive motor can be controlled. Based on the received position information, it can be determined whether the target value has been reached. When the target value is reached, the drive motor is stopped, so that the clamp head can reach the corresponding opening degree. Alternatively, the target value can be combined with the position information to determine the amount of movement (e.g., number of rotations) of the drive motor that needs to be controlled, and then the drive motor can be controlled through the drive circuit. A control method similar to PID algorithm can also be used. It should be noted that the control unit can determine the target value by looking up a table, which is implemented by existing means. Similarly, the control of PID algorithm can also be implemented by existing means, such as the PID control method of patent CN119362257A. Therefore, the embodiments of this application do not involve processing methods or any improvements in algorithms or software.

[0041] like Figure 5 As shown, optionally, the power supply unit may include (B+, B-) and a step-down chip U2 to provide voltages of different magnitudes such as 12V, VCC, and 3.3V to power other modules, such as control units, drive motors, detection units, and input modules connected to the power supply unit.

[0042] like Figure 6 The diagram shows the circuit diagram of the start button KEY S1. The circuit of the start button KEY S1 is connected to the control unit through the SPEEDAD interface.

[0043] Optionally, the drive unit includes a sampling circuit and a drive circuit. The sampling circuit is connected to the drive circuit and the control unit, and the drive circuit is connected to the control unit and the drive motor. The sampling circuit is as follows: Figure 7 As shown, the driving circuit is as follows Figure 8 As shown.

[0044] Optionally, the opening control module may also include an overcurrent protection unit and a reset circuit (not shown) connected to the control unit. The reset circuit can be used to control the drive motor to reverse, so that the transmission mechanism returns to its initial position. The overcurrent protection unit may include a current sampling resistor and a comparator. The current sampling resistor samples the current signal fed back by the drive motor, and the comparator compares the current signal with a reference signal, so that the control unit can stop the drive motor from running when there is an overcurrent.

[0045] Optionally, the housing housing clamp module and the opening control module, the input module are connected and fixed to the housing and exposed in the housing, so that users can easily input using the input module.

[0046] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
