Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical gripper control technology, and more specifically, to a mechanical gripper controller. Background Technology
[0002] In modern industry, mechanical grippers are similar to human hands and are used in conjunction with robotic arms in various production processes, such as handling and assembly, which greatly facilitates our production and life. As a precision drive tool, servo motors can accurately control the rotation angle, have strong stability, and can flexibly adapt to different work contents.
[0003] Most mechanical grippers on the market are sold with servo motors and controllers separately. Even if you buy both the servo motor and controller at the same time, you need to write code to use them. Moreover, every time you modify the opening and closing of the mechanical gripper, you need to modify the code, which is time-consuming and labor-intensive. Non-professionals cannot perform the gripping. Micro servo motors cannot be directly driven by PLCs. Servo servo motors used in PLC industrial control are more expensive than micro servo motors. There is no controller on the market that can directly drive servo motors and adjust their size and opening / closing angle via the screen. Utility Model Content
[0004] To overcome the shortcomings of the existing technology, this utility model provides a mechanical gripper controller, which has the advantages of convenient direct control of the servo motor by the controller and simple operation.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical gripper controller, including a base, a controller assembly fixedly installed at the front of the base, a display screen fixedly installed inside the controller assembly, a control button group and a servo button group fixedly installed at the front of the controller assembly, a servo interface group opened at the top of the controller assembly, and a signal interface group opened at the bottom of the controller assembly.
[0006] As a preferred embodiment of the present invention, a connecting plate is fixedly installed on the outside of the controller assembly, a sliding groove is provided inside the connecting plate, a slider is slidably connected inside the sliding groove, an extrusion plate is fixedly installed in front of the slider, and a slot is provided inside the extrusion plate.
[0007] As a preferred embodiment of this utility model, a fixing plate is fixedly installed in front of the slide groove, and a telescopic rod is fixedly installed on the side of the fixing plate near the slot, with a spring sleeved on the outer side of the telescopic rod.
[0008] As a preferred embodiment of this utility model, the controller assembly has a signal interface group inside, and the base has two screw holes inside, which are located at the left and right ends of the controller assembly, respectively.
[0009] As a preferred embodiment of this utility model, there are four control button groups, all of which are located below the display screen and are circular.
[0010] As a preferred embodiment of this utility model, there are six servo button groups, all of which are located below the four control button groups, and the six servo button groups correspond to the six controlled servos.
[0011] As a preferred embodiment of this utility model, there are six servo interface groups, which are respectively connected to the wiring of six servo motors, and all six servo interface groups are located above the controller assembly.
[0012] As a preferred embodiment of this utility model, there are four signal interface groups, all of which are located below the servo button group. There are multiple connecting plates, slides, sliders, pressing plates, and slots, with the slots located on the side of the six servo interface groups and the four signal interface groups away from the controller assembly.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model features a display screen fixedly installed inside the controller assembly, a control button group and a servo button group fixedly installed at the front of the controller assembly, a servo interface group on the top of the controller assembly, and a signal interface group at the bottom of the controller assembly. When servo control is required, since the controller's main control chip is an STM32F103c8t6 minimum system board, and the servo's wires are connected to the servo interface group for control, the specific parameters of which servo are set through the display screen and control button group, and the servo button group is used for grasping control. This ensures precise control while directly driving the servo, resulting in simple operation and increased control efficiency.
[0015] 2. This utility model features a sliding groove inside the connecting plate, with a slider slidably connected inside the groove. A pressing plate is fixedly installed in front of the slider, and a slot is provided inside the pressing plate. When wiring the servo motor is required, the connector is first inserted into the servo motor interface group. Then, the wire is secured inside the slot. The pressing plate moves the slot through the sliding action of the slider and the groove, pushing the slot towards the controller assembly. This ensures that the connector remains stable after being inserted into the servo motor interface group, preventing vibrations that could cause it to easily fall off. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 5As shown, this utility model provides a mechanical gripper controller, including a base 1, a controller assembly 2 fixedly installed at the front of the base 1, a display screen 3 fixedly installed inside the controller assembly 2, a control button group 4 and a servo button group 5 fixedly installed at the front of the controller assembly 2, a servo interface group 6 opened at the top of the controller assembly 2, and a signal interface group 15 opened at the bottom of the controller assembly 2.
[0024] When servo motor control is required, since the main control chip of the controller is the STM32F103c8t6 minimum system board, and the servo motor's wire terminal is connected to the servo motor interface group 6 for control, the specific parameters of which servo motor are set through the display screen 3 and the control button group 4, and the grasp control is performed through the servo motor button group 5. This ensures that fine control is provided when directly driving the servo motor, and has the effect of simple operation and increased control efficiency.
[0025] Among them, a connecting plate 7 is fixedly installed on the outside of the controller assembly 2, a sliding groove 8 is opened inside the connecting plate 7, a slider 9 is slidably connected inside the sliding groove 8, an extrusion plate 10 is fixedly installed in front of the slider 9, and a slot 11 is opened inside the extrusion plate 10.
[0026] When it is necessary to connect the servo motor to the wiring, first insert the connector into the servo motor interface group 6. Then, snap the wire into the slot 11. The pressing plate 10 moves the slot 11 through the sliding action of the slider 9 and the slide groove 8, and pushes the slot 11 towards the controller assembly 2. This keeps the connector stable after it is inserted into the servo motor interface group 6, preventing the machine from vibrating and causing it to fall off easily.
[0027] A fixing plate 12 is fixedly installed in front of the slide 8. A telescopic rod 13 is fixedly installed on the side of the fixing plate 12 near the slot 11. A spring 14 is sleeved on the outside of the telescopic rod 13.
[0028] Both the spring 14 and the telescopic rod 13 are fixedly connected to the extrusion plate 10. Their main function is to provide elastic force through the spring 14 so that the extrusion plate 10 is always pushed towards the controller assembly 2, thereby keeping the slot 11 stable and ensuring the connection stability between the wire head and the interface.
[0029] The controller assembly 2 has a signal interface group 15 inside, and the base 1 has two screw holes 16 inside. The two screw holes 16 are located at the left and right ends of the controller assembly 2, respectively.
[0030] The main function of the two servo interface groups 6 is to fix the base 1 to the wall by engaging with screws, thereby making the whole device easy to install.
[0031] There are four control button groups 4, all of which are located below the display screen 3 and are circular.
[0032] The four control buttons, group 4, are the "-" button, "+" button, switch button, and confirm button. Their main function is to set operating parameters such as the servo start angle. The switch button and confirm button are mainly used to switch servos and confirm parameter settings.
[0033] There are six servo button groups 5, all of which are located below the four control button groups 4, and each of the six servo button groups 5 corresponds to one of the six controlled servos.
[0034] With six servo button groups 5 distributed throughout, each servo corresponds to a different servo button group 5, thus enabling direct control of which servo to grab and release, preventing mutual interference, and offering simple operation that does not require professional personnel to control, thereby saving overall control costs.
[0035] There are six servo interface groups 6, which are connected to the wiring of six servo motors respectively. All six servo interface groups 6 are located above the controller assembly 2.
[0036] The six servo interface groups 6 are connected to the six servos respectively, so that the controller component 2 can control the six servos at the same time and achieve the effect of simultaneous control.
[0037] There are four signal interface groups 15, all of which are located below the servo button group 5. There are multiple connecting plates 7, slides 8, sliders 9, pressing plates 10 and slots 11. The slots 11 are located on the side away from the controller assembly 2 of the six servo interface groups 6 and the four signal interface groups 15 respectively.
[0038] Multiple slots 11 move by sliding connections between multiple sliders 9 and multiple grooves 8. The circuit is connected and limited to maintain stability. Meanwhile, the four signal interface groups 15 are one power interface and three signal interfaces, respectively, ensuring that the device can operate quickly.
[0039] Working principle and usage process of this utility model:
[0040] Firstly, a display screen 3 is fixedly installed inside the controller assembly 2. A control button group 4 and a servo button group 5 are fixedly installed at the front of the controller assembly 2. A servo interface group 6 is opened on the top of the controller assembly 2, and a signal interface group 15 is opened at the bottom of the controller assembly 2. When the servo needs to be controlled, since the main control chip of the controller is an STM32F103c8t6 minimum system board, and the servo wire is connected to the servo interface group 6 for control, the specific parameters of which servo are set are set through the display screen 3 and the control button group 4, and the servo button group 5 is used for grasping control. This ensures that fine control is provided when directly driving the servo, and has the effect of simple operation and increased control efficiency.
[0041] Secondly, since a sliding groove 8 is provided inside the connecting plate 7, a slider 9 is slidably connected inside the sliding groove 8, and a pressing plate 10 is fixedly installed in front of the slider 9, and a slot 11 is provided inside the pressing plate 10, when it is necessary to connect the servo motor to the wiring, first insert the connector into the servo motor interface group 6, and then snap the wiring into the slot 11. The pressing plate 10 moves the slot 11 through the sliding action of the slider 9 and the sliding groove 8, and pushes the slot 11 towards the controller assembly 2, so that the interface remains stable after being inserted into the servo motor interface group 6, preventing the machine from vibrating and easily falling off.
[0042] Finally, since there are six servo button groups 5, each corresponding to one of the six controlled servos, it allows direct control of which servo to grab and release without mutual interference. It is also simple to operate, does not require professional personnel to control, and saves on overall control costs.
