Description

Technical Field

[0001] This utility model relates to the field of clamping and transfer equipment technology, and in particular to a high-precision resistor gripper device. Background Technology

[0002] A resistor is an electronic component that limits the amount of current passing through the branch it is connected to, preventing excessive current in the circuit from damaging other components. For example, a resistor is connected in series in an LED circuit to limit the current and protect the LED. It is made by utilizing the material's resistance to current and is mainly used to control the current and voltage in a circuit. In the processing and production of resistors, gripper equipment is required for transport.

[0003] When the grippers receive a control signal, they are driven to open or close. For example, in an electric drive mode, the motor drives the grippers to open and close via the rotation of gears or screws. When the grippers open, the resistor can be placed inside; when the grippers close, the resistor is clamped and fixed. However, the gripper surfaces of existing gripper devices tend to accumulate dust and oil, which affects their performance and lifespan. Current solutions involve cleaning the grippers, removing dust and oil, and using detergents or alcohol to clean the surface and maintain cleanliness and good performance. However, friction between the grippers and the resistor during the gripping process still causes wear on the grippers, leading to a decrease in clamping force and affecting the clamping effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-precision resistor clamping device, which aims to improve the problem in the prior art where friction between the clamping jaws and the resistor causes wear of the clamping jaws, resulting in a decrease in the clamping force of the clamping jaws and thus affecting the clamping effect of the resistor.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-precision resistance gripper device, comprising a fixed shell, a negative pressure fan fixedly connected to the inner bottom wall of the fixed shell, a negative pressure pipe connected to the right side of the negative pressure fan, a negative pressure ring connected to the bottom end of the negative pressure pipe, a robotic arm fixedly connected to the bottom wall of the fixed shell, a fixed plate fixedly connected to the bottom wall of the robotic arm, pneumatic clamps rotatably connected to the four corners of the bottom wall of the fixed plate, multiple connecting pipes equidistantly connected to the top wall of the negative pressure ring, a negative pressure shell connected to the bottom end of the connecting pipes, a filter plate fixedly connected to one side of the negative pressure shell, a bottom wall of the negative pressure shell fixedly connected to the pneumatic clamp, and an installation mechanism provided on the rear side of the fixed shell, the installation mechanism being used to improve the adaptability range of flexible installation of the device.

A mounting housing is attached to the right side of the electric push rod. A bolt is threadedly connected to the top wall of the mounting housing. A replacement clamp is threadedly connected to the bottom end of the bolt. The left end of the replacement clamp engages with the right side of the mounting housing.

[0009] The installation mechanism also includes two rubber pads. The left side of the left rubber pad is fixedly connected to the right side of the fixing clamp, and the right side of the right rubber pad is on the left side of the replacement clamp.

[0010] As a further description of the above technical solution:

[0011] A control switch is fixedly connected to the left side of the fixed housing. The control switch is electrically connected to the negative pressure fan, the pneumatic clamp, and the electric push rod.

[0012] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] A handle is fixedly connected to the top wall of the fixed shell, and a rubber sleeve is fixedly connected to the middle of the handle.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the rotation of the pneumatic clamp causes the negative pressure shell to make initial contact with the resistor block. Then, driven by the negative pressure fan, the air inside the negative pressure shell is extracted, thereby completing the negative pressure fixation of the side in contact with the resistor block. This improves the fixing effect of the resistor block, while reducing the clamping damage of the pneumatic clamp to the resistor block and avoiding the decrease in clamping force of the jaws from affecting the clamping effect of the resistor.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a high-precision resistance gripper device, comprising a fixed shell 1, a negative pressure fan 3 fixedly connected to the inner bottom wall of the fixed shell 1, a negative pressure pipe 4 connected to the right side of the negative pressure fan 3, and a negative pressure ring 5 connected to the bottom end of the negative pressure pipe 4, so that when the negative pressure fan 3 is started, the air inside the negative pressure ring 5 is extracted, thereby completing the subsequent negative pressure operation. A robotic arm 6 is fixedly connected to the bottom wall of the fixed shell 1, and a fixed plate 7 is fixedly connected to the bottom wall of the robotic arm 6. Pneumatic clamps 8 are rotatably connected to the four corners of the bottom wall of the fixed plate 7, so that when the pneumatic clamps 8 are working... The initial contact with the resistor block is completed. At the same time, under the connection of the robotic arm 6, the fixing plate 7 completes the lifting and rotation. Multiple connecting pipes 9 are equidistantly connected to the top wall of the negative pressure ring 5. The bottom end of the connecting pipe 9 is connected to the negative pressure shell 10. Then, under the connection of the connecting pipe 9, the negative pressure shell 10 synchronously fixes the resistor block with negative pressure through the filter plate 11. The filter plate 11 is fixedly connected to one side of the negative pressure shell 10. The top wall of the negative pressure shell 10 is fixedly connected to the bottom of the pneumatic clamp 8. The rear side of the fixing shell 1 is provided with an installation mechanism 2. The installation mechanism 2 is used to improve the adaptability range of flexible installation of the device.

[0032] Specifically, by controlling the rotation of the pneumatic clamp 8, the negative pressure shell 10 can make initial contact and clamp the resistor block. With the start of the negative pressure fan 3, the negative pressure pipe 4 and the negative pressure ring 5 work together to complete the airflow extraction process. Through the connection of the connecting pipe 9, the air inside the negative pressure shell 10 is extracted, and a negative pressure is formed on the side of the negative pressure shell 10 that contacts the resistor block, thereby achieving a stable fixation of the resistor block. This fixing method improves the fixing effect of the pneumatic clamp 8 on the resistor block, while reducing the damage that the pneumatic clamp 8 may cause when clamping the resistor block. In addition, it avoids the problem that the clamping force of the pneumatic clamp 8 will decrease due to wear, thus affecting the clamping effect of the resistor. Finally, through the operation of the robotic arm 6, the resistor block is successfully transferred to the designated position.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The installation mechanism 2 includes a fixed plate 201. The front side of the fixed plate 201 is fixedly connected to the rear side of the fixed shell 1. A fixed clamp 202 is fixedly connected to the rear side of the fixed plate 201. An electric push rod 203 on the right side of the fixed clamp 202 is initially engaged with the installation position through the fixed clamp 202. Driven by the electric push rod 203, the installation shell 204 drives the replacement clamp 207 to move synchronously, thereby clamping and fixing the installation position. The right side of the electric push rod 203 is connected to the installation shell 204. A bolt 205 is threadedly connected to the top wall of the installation shell 204. The replacement clamp 207 is threadedly connected to the bottom end of the bolt 205. Then, under the rotation of the bolt 205, the replacement operation of the replacement clamp 207 is completed. The left end of the replacement clamp 207 is engaged with the right side of the installation shell 204.

[0034] Specifically, by rotating the bolt 205, the internal locking between the replacement clamp 207 and the mounting housing 204 is released. By pulling the replacement clamp 207, the replacement clamp 207 can be replaced, allowing the equipment to adapt to various installation positions and requirements. Driven by the electric push rod 203, its right end drives the mounting housing 204 to move. By reducing the distance between the replacement clamp 207 and the fixed clamp 202, the fixed installation of the device can be effectively completed, improving the flexibility of the device and expanding the adaptability of the clamp, making it suitable for more types of equipment and environments.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The installation mechanism 2 also includes two rubber pads 208. The left side of the left rubber pad 208 is fixedly connected to the right side of the fixing clamp 202, and the right side of the right rubber pad 208 is on the left side of the replacement clamp 207. A control switch 13 is fixedly connected to the left side of the fixing shell 1. The control switch 13 is electrically connected to the negative pressure fan 3, the pneumatic clamp 8 and the electric push rod 203 respectively. A rubber column 14 is fixedly connected to the middle of one side of each of the multiple pneumatic clamps 8. One side of the rubber column 14 is designed to be smooth.

[0036] Specifically, the rubber pad 208 improves the fixing effect of the fixed position, and the control switch 13, which is electrically connected to the negative pressure fan 3, the pneumatic clamp 8 and the electric push rod 203 respectively, enables the control switch 13 to complete the opening and closing of the equipment. The rubber column 14 improves the protection of the resistor block.

[0037] Reference Figure 2 and Figure 3 A rubber ring 12 is fixedly connected to the bottom of the outer wall of the negative pressure pipe 4, and the outer wall of the rubber ring 12 is fixedly connected to the front side of the negative pressure ring 5; the installation mechanism 2 also includes a rubber ring 206, and the inner wall of the rubber ring 206 is fixedly connected to the middle of the bolt 205; a handle 15 is fixedly connected to the top wall of the fixed shell 1, and a rubber sleeve 16 is fixedly connected to the middle of the handle 15.

[0038] Specifically, the rubber ring 12 protects the bottom connection of the negative pressure pipe 4, the rubber ring 206 reduces the rotational damage of the bolt 205 to the mounting shell 204, and the rubber sleeve 16 improves the anti-slip effect of the handle 15.

[0039] Working principle: At the beginning of use, the pneumatic clamp 8 is rotated by the device, which drives the negative pressure shell 10 to make initial contact and clamp the resistor block. Then, with the start of the negative pressure fan 3, the air is drawn through the negative pressure pipe 4 and the negative pressure ring 5. Then, with the connection of the connecting pipe 9, the air inside the negative pressure shell 10 is drawn out, so that the side of the negative pressure shell 10 in contact with the resistor block forms a negative pressure fixation, thereby improving the fixing effect of the pneumatic clamp 8 on the resistor block, while reducing the clamping damage of the pneumatic clamp 8 on the resistor block, and avoiding the situation where the clamping force of the pneumatic clamp 8 decreases due to wear, which affects the clamping effect of the resistor. Then, the mechanical arm 6 completes the transfer of the resistor block.

[0040] Furthermore, by rotating the bolt 205, the replacement clamp 207 is unlocked from the interior of the mounting shell 204. Then, the replacement clamp 207 is pulled to achieve the purpose of replacing the replacement clamp 207, so as to adapt to different installation positions and requirements. Then, under the drive of the electric push rod 203, its right end drives the mounting shell 204 to move. Then, by reducing the distance between the replacement clamp 207 and the fixed clamp 202, the device is fixedly installed, which improves the flexibility of the device and increases the compatibility range of the clamp.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
