Description

Technical Field

[0001] The present invention relates to the technical field of mechanical arms, and in particular to a mechanical arm for adjusting the direction of a part. Background Art

[0002] The robot arm used to adjust the direction of parts is a key automation equipment in modern manufacturing, especially suitable for production lines with strict direction requirements for part installation. The system achieves efficient and accurate part grabbing and installation through the collaborative work of two cameras and a robot arm. This system design of two cameras and one robot arm not only improves the accuracy and speed of part installation, but also greatly reduces the error and labor intensity of manual operation. It is widely used in electronic assembly, automobile manufacturing, precision instrument production and other fields, providing efficient and reliable solutions for modern industrial automation.

[0003] However, the existing robotic arms for adjusting the direction of parts need to frequently move back and forth between the conveyor belts to pick up and assemble parts. This repetitive movement not only wastes time, but also reduces assembly efficiency. Frequent robotic arm movement and adjustment consumes a lot of electrical energy, accelerates the wear of the robotic arm and its components, leads to high energy consumption, shortens its service life, and increases production costs. And because the robotic arm moves back and forth between the conveyor belts at a high frequency, it can only handle one or a small number of parts at a time, which makes the assembly process inefficient, the production cycle is long, and affects production capacity. In addition, the residual heat of the parts cannot be effectively handled during the assembly process, which may cause the parts to deform or degrade due to high temperature, thereby affecting the assembly quality and product life. In addition, the traditional robotic arm cannot remove the processing debris on the surface of the parts before assembly, which may lead to poor assembly or finished product defects. If additional equipment and processes are added to the assembly line to handle the cooling or chip removal functions of the parts, the complexity and cost of the production line will be increased. At the same time, it will also extend the assembly time and reduce production efficiency. Summary of the invention

A plurality of clamping plates for clamping the workpiece are slidably arranged in the fixed clamping plate, and the clamping plate can slide in a direction perpendicular to the inner surface of the fixed clamping plate. A screw is also slidably arranged in the fixed clamping plate in a vertical direction, and the bottom shape of the screw is an inverted cone. When the screw moves vertically downward, the clamping plate is lifted and moves toward the outside of the fixed clamping plate, so that the clamping plate clamps the workpiece.

[0009] Preferably, a piston is installed inside the connecting rod, and when the push plate end of the piston moves downward, it pushes the workpiece clamped by the clamp plate to move downward, and during the pushing process, the main body of the robotic arm moves downward synchronously, causing the fixed clamp plate and the sliding clamp plate to slide until the bottom edge of the fixed clamp plate contacts the second conveyor belt.

[0010] Preferably, a magnetic plate is provided at the bottom of the airbag, and a magnetic block is provided inside the bottom end of the sliding clamp, and the magnetic block has a different magnetic pole from the magnetic plate; the magnetic block absorbs the magnetic plate and resets the airbag.

[0011] Preferably, reset rods are provided between the two ends of the clamp plate and the fixed clamp plate, and the reset rods are made of elastic material.

[0012] Preferably, a semi-ring plate matching the screw is provided on the back of the clamp plate, and when the screw does not lift up the clamp plate, the semi-ring plate and the screw are eccentrically arranged, and when the screw completely lifts up the clamp plate, the semi-ring plate and the screw are coaxially arranged.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a mechanical arm for adjusting the direction of parts, which has the following beneficial effects:

[0018] 1. The robot arm for adjusting the direction of parts, through the cooperation of the clamp module, when the robot arm body is assembling the outer cover and the inner cover on the first conveyor belt and the second conveyor belt, the robot arm body can pick up multiple outer covers at different positions on the first conveyor belt and stack and clamp them in the clamp module. After the clamp module clamps multiple outer covers, the robot arm body only needs to rotate to the second conveyor belt once to assemble multiple inner covers with the outer cover, thereby reducing the repeated rotation of the robot arm body during the assembly process, reducing the repeated movement of the robot arm body makes the assembly process more efficient, and the robot arm body can complete an assembly cycle faster, thereby improving the overall efficiency and production capacity of the production line; and in the assembly process of the outer cover and the inner cover, when the direction of the inner cover on the second conveyor belt is unified, since the distance between the sliding clamps at both ends is greater than that of the inner cover, when repeatedly clamping the inner cover and the outer cover, it is only necessary to wait for the inner cover to move below the sliding clamp, and then the quick clamping can be completed by driving the fixed clamp to press down. During this period, the robot arm body does not need to rotate, and only needs to repeatedly press down the fixed clamp, thereby reducing the movement of the robot arm body and improving the assembly efficiency.

[0019] 2. The robot arm for adjusting the direction of parts, through the coordinated use of the telescopic gas rod structure, the air bag structure, and the main structure of the robot arm, can inflate the telescopic gas rod by starting the air pump assembly, and the gas will be ejected from the suction holes on the surface of the suction cup. The gas will form a rotating airflow around the outer cover or the inner cover, and the airflow will effectively reduce the surface temperature of the outer cover or the inner cover, and at the same time blow off the processing debris attached to the surface, and this function is an auxiliary function attached to the suction cup structure, and can be achieved without adding additional structure. Therefore, no additional equipment is required, and the processing debris on the surface of the outer cover and the inner cover can be cleared during the clamping process, which simplifies the production process and equipment structure, saves manual cleaning time and processes, and enables the production line to operate with higher efficiency.

[0020] 3. The robot arm for adjusting the direction of parts is used through the cooperation of the telescopic gas rod structure and the airbag structure. Since the suction cup and the airbag structure themselves can be inflated and evacuated through the air pump assembly, the generation and control of the airflow are completed through the existing air pump assembly without the need for additional airflow generating equipment. The air pump assembly is used for both the negative pressure adsorption function of the suction cup and the generation and release of airflow. Only the air pump assembly is needed to realize multiple functions without the need to install additional equipment, which directly reduces the equipment procurement and maintenance costs and simplifies the structure of the entire assembly system.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A robot arm for adjusting the direction of parts, including a robot arm body 1, a first conveyor belt 2, and a second conveyor belt 3. The robot arm body 1 is arranged between the first conveyor belt 2 and the second conveyor belt 3. The first conveyor belt 2 and the second conveyor belt 3 are both provided with camera modules 6 on top. The robot arm body 1 grabs the parts based on the position of the parts obtained by the first camera module 6, and then adjusts the grabbed parts for installation in combination with the data of the second camera module 6. A fixture module 4 is installed at the end of the robot arm body 1. The fixture module 4 includes a connecting rod 41, a sliding clamp 42, and a fixed clamp 43. The fixed clamps 43 are fixedly arranged at both ends of the bottom of the connecting rod 41. The fixed clamp 43 provides a stable support base for the fixture. The robot arm is connected by the connecting rod 41, which can maintain the stability and position accuracy of the fixture. This ensures that the fixture will not be offset when grabbing and placing the workpiece 7, thereby improving the assembly accuracy. The fixed clamping plate 43 is slidably connected to the sliding clamping plate 42 on both sides, and the sliding clamping plate 42 can slide on both sides of the fixed clamping plate 43, so that the clamp can flexibly adjust the grasping range. This helps to grasp workpieces 7 of different sizes and shapes during the assembly process, and increases the applicability and flexibility of the clamp. An air bag 421 is slidably arranged inside the sliding clamping plate 42, and a telescopic gas rod 424 is arranged on the top of the air bag 421. A suction cup 422 for adsorbing the workpiece 7 is arranged on the outside of the air bag 421, and a suction hole connected to the inside of the suction cup 422 is opened. This design uses the air bag 421 and the telescopic gas rod 424 to generate negative pressure to achieve adsorption of the workpiece 7. The air bag 421 and the telescopic gas rod 424 can be flexibly adjusted so that the suction cup 422 can form a stable adsorption force on the surface of the workpiece 7. The adsorption and release operations are performed through the air holes, so that the workpiece 7 can be effectively grasped and placed, and the cooling and cleaning functions of the workpiece 7 are realized at the same time, thereby improving the efficiency and quality of the assembly process. When the suction cup 422 absorbs the workpiece 7, negative pressure is generated in the airbag 421 and the telescopic air rod 424 is retracted upward. Fig.14 As shown, a plurality of fixture plates 431 for clamping the workpiece 7 are slidably arranged in the fixed clamp plate 43. The fixture plates 431 can slide in a direction perpendicular to the inner surface of the fixed clamp plate 43. The design of multiple fixture plates 431 enables the fixture to clamp multiple workpieces 7 at the same time, greatly improving the assembly efficiency. The fixture plate 431 can slide vertically to ensure that the workpiece 7 can be accurately aligned and stably clamped when grabbing and placing the workpiece 7, so as to prevent the workpiece 7 from shifting or falling off during transportation and assembly. A screw rod 432 is also slidably arranged in the fixed clamp plate 43 in the vertical direction. The bottom shape of the screw rod 432 is an inverted cone. The vertical sliding and inverted cone bottom of the screw rod 432 are designed to drive the clamping and release of the fixture plate 431. When the screw rod 432 moves downward, the inverted cone bottom can push the fixture plate 431 away to clamp the workpiece 7; when the screw rod 432 moves upward, the fixture plate 431 releases the workpiece 7. In this way, precise clamping and releasing operations can be achieved, increasing the accuracy and reliability of the assembly process. Figure 8 , Fig.10 , Fig.13 , Fig.15 When the screw rod 432 moves vertically downward, the clamping plate 431 is lifted up and moves toward the outside of the fixed clamping plate 43, so that the clamping plate 431 clamps the workpiece 7.

[0039] See also Figure 6 , Figure 7 , Figure 8 , Fig.11 , Fig.12 , Fig.13 , a piston 5 is installed inside the connecting rod 41. When the push plate end of the piston 5 moves downward, it pushes the workpiece 7 clamped by the clamp plate 431 to move downward. The piston 5 can provide a stable and uniform downward force to ensure that the workpiece 7 can be accurately assembled in place. When the push plate end of the piston 5 moves downward, the workpiece 7 clamped by the clamp plate 431 can be pushed to a predetermined position, thereby improving the accuracy and reliability of the assembly process. In the pushing process, the robot arm body 1 moves downward synchronously, causing the fixed clamp plate 43 and the sliding clamp plate 42 to slide until the bottom edge of the fixed clamp plate 43 contacts the second conveyor belt 3. In the pushing process, the synchronous downward movement of the robot arm body 1 can ensure the accuracy of the relative position between the clamp module 4 and the conveyor belt. The relative sliding of the fixed clamp plate 43 and the sliding clamp plate 42 can adapt to the height and position changes of the workpiece 7, ensuring that the clamp plate 431 can accurately clamp the workpiece 7. This design can improve the flexibility and adaptability of the assembly process and ensure that the workpiece 7 is firmly assembled in place. A magnetic plate 423 is provided at the bottom of the airbag 421, and a magnetic block 425 is provided inside the bottom end of the sliding clamp plate 42. The magnetic block 425 has different magnetic poles from the magnetic plate 423; the magnetic block 425 adsorbs the magnetic plate 423 and resets the airbag 421. The design of the magnetic plate 423 and the magnetic block 425 enables the airbag 421 to automatically reset after adsorbing and releasing the workpiece 7, ensuring that the airbag 421 can return to the initial state after each operation and prepare for the next operation. This automatic reset function improves the continuity and efficiency of the assembly process and reduces the necessity of human intervention. A reset rod 434 is provided between the two ends of the clamp plate 431 and the fixed clamp plate 43, and the reset rod 434 is made of elastic material. After the clamp plate 431 completes the clamping operation, the reset rod 434 can provide an outward restoring force to return the clamp plate 431 to the initial position and prepare for the next operation. The elastic material provides a soft and stable reset force, avoiding excessive impact force generated by the clamp plate 431 during the reset process, and extending the service life of the clamp. The elastic material is selected from rubber or spring steel, which has good elasticity and durability. These materials can maintain stable elastic properties during multiple cycles of use and are not prone to fatigue or deformation, thereby ensuring that the reset rod 434 can work stably for a long time and ensuring the continuity and reliability of the assembly process.

[0040] See also Figure 8 , Fig.10 , Fig.13 , Fig.15A semi-ring plate 435 matching the screw rod 432 is disposed on the back of the fixture plate 431. When the screw rod 432 does not lift up the fixture plate 431, the semi-ring plate 435 and the screw rod 432 are eccentrically disposed. When the screw rod 432 fully lifts up the fixture plate 431, the semi-ring plate 435 and the screw rod 432 are coaxially disposed. The eccentric arrangement design ensures that the fixture plate 431 will not be activated by misoperation when the screw rod 432 does not lift up the fixture plate 431. Only when the screw rod 432 fully lifts up the fixture plate 431, the semi-ring plate 435 and the screw rod 432 are coaxially disposed. This ensures that the fixture plate 431 is activated at the correct position and time to clamp the workpiece 7. This design improves the reliability and accuracy of the fixture plate 431 operation and avoids misoperation. Please refer to Figure 1 , Figure 3 , Figure 8 , the connecting rod 41 is rotationally connected to the robot arm body 1. The rotational connection allows a certain degree of flexibility between the connecting rod 41 and the robot arm body 1. This design can make it easier for the fixture module 4 to adjust the angle and position, thereby more accurately aligning the workpiece 7. This flexibility helps to cope with workpieces 7 of different sizes and shapes, and improves the adaptability and flexibility of the assembly process. A drive motor 433 is provided at the top of the screw 432 to drive it to slide up and down. The drive motor 433 is threadedly connected to the screw 432, and the drive motor 433 is fixedly mounted on the connecting rod 41. The drive motor 433 controls the up and down sliding of the screw 432 through a threaded connection, which can provide precise displacement control. This design allows precise control of the clamping and releasing actions of the fixture plate 431, ensuring the repeatability and reliability of each operation.

[0041] See also Figure 7 , Fig.12 , Fig.14 The top of the telescopic gas rod 424 passes through the sliding splint 42 and is fixedly connected to the sliding splint 42. The telescopic gas rod 424 is connected to an air pump assembly. This design ensures that the telescopic gas rod 424 can accurately control the telescopic action of the airbag 421. Passing through the sliding splint 42 and being fixedly connected can ensure that the airbag 421 is accurately positioned when adsorbing and releasing the workpiece 7. Connecting the air pump assembly can provide the required air pressure changes to ensure that the adsorption and release actions proceed smoothly. When the telescopic gas rod 424 is evacuated, the suction cup 422 adsorbs the workpiece 7 and forms a negative pressure in the airbag 421, and the telescopic gas rod 424 contracts upward; when the telescopic gas rod 424 is inflated, the suction cup 422 separates from the workpiece 7, and the pressure in the airbag 421 increases, the telescopic gas rod 424 extends and resets the airbag 421.

[0042] Working principle: When using the robot arm, firstly, the direction of the workpiece 7 on the first conveyor belt 2 and the second conveyor belt 3 is detected through the camera module 6, wherein the outer cover is placed on the first conveyor belt 2, and the inner cover is placed on the second conveyor belt 3. During the processing, the outer cover needs to be put on the inner cover. Then the robot arm body 1 moves and aligns the clamp module 4 with the outer cover, and the two ends of the sliding clamp 42 are located on both sides of the outer cover; the air pump assembly is started to evacuate air, so that negative pressure is generated in the telescopic gas rod 424 and the air bag 421, which will cause the suction cup 422 to be adsorbed on the surface of the outer cover. Then, because the suction hole on the suction cup 422 is blocked by the outer cover, a closed space is formed between the suction cup 422 and the side of the outer cover. Since the gas in the suction cup 422 has been partially extracted, the amount of gas in the air bag 421 and the telescopic gas rod 424 is reduced, resulting in a decrease in internal pressure. Since the telescopic gas rod 424 is connected to the air bag 421, when the pressure in the air bag 421 decreases, the telescopic gas rod 424 will shrink upward, such as Fig.12 As shown in the direction of the arrow, after contraction Fig.14 As shown, the volume inside the airbag 421 is reduced, so that the gas density inside the airbag 421 increases, and then the internal pressure tends to be balanced, so that the airbag 421 drives the outer cover to move up along the sliding clamp plate 42 to the clamp plate 431. When the outer cover moves to the clamp plate 431, the drive motor 433 drives the screw 432 to move downward. During the downward movement of the screw 432, the clamp plate 431 is squeezed inward, and the screws 432 in the fixed clamp plates 43 on both sides are synchronously operated; the clamp plate 431 is gradually squeezed inward to clamp the two ends of the outer cover. The movement direction of the clamp plate 431 is as shown in FIG. Fig.13 As shown in the direction of the middle arrow, the outer cover is fixed on the fixed clamping plate 43, and then the driving motor 433 stops, and the air pump assembly inflates the telescopic air rod 424, so that the pressure in the telescopic air rod 424 and the air bag 421 increases, which will cause the suction cup 422 to leave the surface of the outer cover, and the telescopic air rod 424 will extend and drive the air bag 421 to move downward until the magnetic plate 423 at the bottom of the air bag 421 and the magnetic block 425 in the sliding clamping plate 42 are mutually attracted, and the air bag 421 is reset. The above process is repeated several times until the outer cover is clamped on the several clamping plates 431 in the fixed frame plate, and then the robot arm body 1 rotates again to make the clamping module 4 located above the second conveyor belt 3 to assemble the outer cover and the inner cover.

[0043] When assembling the outer cover and the inner cover, the robot arm body 1 first moves to align the clamp module 4 with the inner cover on the second conveyor belt 3, so that the sliding clamp plate 42 is supported on the surface of the second conveyor belt 3, and then the robot arm body 1 controls the connecting rod 41 to press vertically downward. At this time, since the connecting rod 41 and the fixed clamp plate 43 are fixedly connected, the fixed clamp plate 43 will slide relative to the sliding clamp plate 42, and the fixed clamp plate 43 moves toward the workpiece 7. When the two ends of the fixed clamp plate 43 contact the surface of the second conveyor belt 3, the outer cover clamped at the bottom of the fixed clamp plate 43 contacts and engages with the inner cover. After the outer covers are assembled together, the screw rod 432 then moves upward to cancel the clamping of the outer cover, and the piston 5 is started to press downward. Since the outer covers are stacked together after the clamping is canceled, the bottom outer cover will be completely assembled with the inner cover through the downward pressure of the piston 5. Then the robot body 1 controls the connecting rod 41 to drive the fixed clamp plate 43 to move up the height of one outer cover, so that the bottom outer cover is completely separated from the fixed clamp plate 43. At the same time, the screw rod 432 moves downward again to re-clamp several outer covers by the clamp plate 431, and then the robot body 1 controls the clamp module 4 as a whole to leave the surface of the second conveyor belt 3. Repeat the above process to assemble the outer cover and the inner cover until there is no outer cover in the fixed clamp plate 43.

[0044] Traditional robot arms need to frequently move back and forth between conveyor belts to pick up and assemble parts. This repetitive movement not only wastes time, but also reduces assembly efficiency. Frequent robot arm movement and adjustment require a large amount of electrical energy, accelerate the wear of the robot arm and its components, lead to high energy consumption, shorten its service life, and increase production costs. And because the robot arm moves back and forth between the conveyor belts at a high frequency, it can only process one or a small number of parts at a time, which makes the assembly process inefficient, the production cycle is long, and the production capacity is affected. When the robot arm body 1 using the clamp module 4 of the present invention is assembled on the outer cover and the inner cover on the first conveyor belt 2 and the second conveyor belt 3, since multiple outer covers can be clamped in the fixed clamping plate 43, the rotation frequency of the robot arm body 1 between the first conveyor belt 2 and the second conveyor belt 3 can be greatly reduced, and only a single rotation is required to clamp multiple outer covers from the first conveyor belt 2 to the second conveyor belt 3 for assembly of the inner cover and the outer cover, thereby reducing the repeated rotation of the robot arm body 1. Reducing the repeated movement of the robot arm makes the assembly process more efficient. The robot arm can complete an assembly cycle faster, thereby improving the overall efficiency and production capacity of the production line. Rapid assembly can shorten production cycles and increase production line output.

[0045] At the same time, in the process of assembling the outer cover and the inner cover, since the outer cover and the inner cover to be assembled from the first conveyor belt 2 and the second conveyor belt 3 both have residual heat from the shaping, and debris is usually attached to their surfaces, after the fixture module 4 is aligned with the outer cover or the inner cover, the rotation of the fixture module 4 can be controlled by the robot arm body 1, and the air pump assembly is started to inflate the telescopic gas rod 424, and the gas will be ejected from the suction hole on the surface of the suction cup 422. The gas will form a rotating airflow around the outer cover or the inner cover, and the airflow will effectively reduce the surface temperature of the outer cover or the inner cover, and blow off the processing debris attached to the surface, and this function is an auxiliary function attached to the suction cup 422 structure, and can be realized without adding an additional air pump or structure. At the same time, this method has good applicability to parts of various materials and shapes, whether plastic, metal or other materials, can be effectively cooled and cleaned by airflow. However, the traditional robot arm cannot effectively handle the residual temperature of the parts during the assembly process, which may cause the parts to deform or degrade due to high temperature, thereby affecting the assembly quality and product life. In addition, traditional robotic arms cannot remove processing debris from the surface of parts before assembly, which may lead to poor assembly or finished product defects. If additional equipment and processes are added to the assembly line to handle the cooling or chip removal functions of the parts, the complexity and cost of the production line will increase. At the same time, it will also extend the assembly time and reduce production efficiency. The present invention uses airflow cooling and cleaning as part of the assembly structure and assembly process, does not require additional equipment, simplifies the production process and equipment structure, saves manual cleaning time and processes, and enables the production line to operate at a higher efficiency.
