Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1:
[0025] Combination Figure 1-3 The robotic arm shown is used for the turnover of suspended disc-shaped porcelain insulator blanks. The core of the robotic arm 1 is to combine the robotic arm 1 with an adjustable suction structure. The robotic arm 1 serves as the basic load-bearing component, and its end is connected to the suction adjustment component 2 through a precision drive mechanism, which provides the motion basis for the subsequent adjustment and gripping of the insulator blank. Two sets of suction components 3 are arranged opposite each other on the suction adjustment component 2. The two sets of suction components 3 cooperate with each other to form a more balanced adsorption and clamping effect, avoiding uneven gripping force and unstable adsorption that could cause the blank to shift, be scratched or fall off.
[0026] In the suction adjustment assembly 2, the suction adjustment base plate 201 serves as the carrier of the entire adjustment mechanism. Its internal cavity houses the guide slide rail 202, which acts like a precision motion track. Two sets of guide sliders 203 can slide smoothly along the guide slide rail 202. The support platforms 204 at both ends above the guide slide rail 202 play a crucial foundational support role. Each support platform 204 is equipped with two sets of bearings 205, which precisely support the bidirectional threaded rod 206 between them. The bidirectional threaded rod 206, through a unique bidirectional thread design, cooperates with two sets of ball nut seats 207. When the bidirectional threaded rod 206 rotates, the two sets of ball nut seats 207 can move in opposite directions or towards each other along the axial direction of the bidirectional threaded rod 206. It is worth mentioning that the two sets of ball nut seats 207 are respectively fixedly connected to the guide sliders 203 at the same end, and... An extension arm 208 extends from the ball nut seat 207. This structural design realizes the conversion of the rotational motion of the bidirectional threaded rod 206 into the linear movement of the suction assembly 3. In terms of power transmission, the driven gear 209 at the end of the bidirectional threaded rod 206 cooperates with the adjustment motor 2010 on the side wall of the suction adjustment base plate 201. An adjustment gear 2011 is set on the rotating shaft of the adjustment motor 2010. The adjustment gear 2011 and the driven gear 209 transmit power through the toothed belt 2012. When the adjustment motor 2010 starts, the power is transmitted to the driven gear 209 through the adjustment gear 2011 and the toothed belt 2012, thereby driving the bidirectional threaded rod 206 to rotate, and finally realizing the flexible adjustment of the distance between the two sets of suction assemblies 3.
[0027] Specifically, for the suction component 3, the suction support 301 fixed on the extension arm 208 provides stable support for the suction component 302. The suction component 302 is hollow inside, and the negative pressure connector 303 on its side wall can be connected to an external negative pressure device. During operation, the external negative pressure device creates a negative pressure inside the suction component 302 through the negative pressure connector 303. At this time, the suction holes 304 evenly distributed on the surface of the suction component 302 become the output port of the adsorption force. To enhance the adsorption effect and sealing, the surface of the suction component 302 is covered with a gasket 305. The through holes on the gasket 305 that match the suction holes 304 can not only ensure the transmission of negative pressure, but also better fit the surface of the blank through the flexible deformation of the gasket 305 when in contact with the insulator blank, thereby improving the adsorption stability. In addition, it can also prevent the suction component 302 from directly contacting the insulator blank and causing surface scratches.
[0028] In this embodiment, the anti-collision design of the side wall of the support platform 204 is a key part of ensuring the stable operation of the equipment. The anti-collision column, made of highly elastic rubber, provides reliable protection for the absorption and adjustment component 2 due to its unique physical properties. The rubber material has excellent buffering and energy absorption effects. When the ball nut seat 207 moves along the guide rail 202 under the drive of the bidirectional threaded rod 206, even if it moves rapidly due to unexpected situations or program control errors, the anti-collision column can effectively absorb the impact force generated by the collision due to its own elastic deformation, converting the impact force into the elastic potential energy inside the rubber and gradually dissipating it.
[0029] In this embodiment, the ingenious arrangement of the driven gear 209 and the adjusting gear 2011 on the same vertical plane has the following advantages: From the perspective of transmission efficiency, when the driven gear 209 and the adjusting gear 2011 are on the same vertical plane, the toothed belt 2012 can be tensioned between the two gears in an ideal state with almost a straight line. This vertical arrangement greatly reduces the friction loss and energy loss of the toothed belt 2012 during operation, making the power transmission more direct and efficient. From the perspective of structural stability, it avoids gear deviation or toothed belt deviation caused by uneven force, and ensures that the position adjustment of the suction component 3 is accurate.
[0030] In this embodiment, the suction support 301 and the suction member 302 are designed with an arc-shaped cross section. The arc-shaped suction member 302 can better fit the curved contour of the insulator blank. When in contact with the blank, the distribution area of the suction holes 304 forms a larger contact area with the surface of the blank. With the help of negative pressure, a stronger and more uniform adsorption force can be generated. The end connection of the negative pressure connector 303 is provided with an annular sealing groove, and a circular sealing ring is provided in the annular sealing groove to ensure the stability of the negative pressure system after connection.
[0031] In this embodiment, the gasket 305 is made of silicone material with a thickness of 1.5-2.5mm. The inner diameter of the through hole is 0.5-1mm larger than the inner diameter of the suction hole 304. Silicone material has excellent flexibility and elasticity. During the negative pressure adsorption process, it can closely fit the slight undulations and irregular contours of the insulator blank surface to form a reliable sealing space, effectively preventing air leakage and ensuring stable output of negative pressure adsorption force. The thickness of the gasket 305 is set in the range of 1.5-2.5mm. The appropriate thickness gives the gasket 305 sufficient elastic deformation capacity. When in contact with the blank, it can not only compress itself to fit tightly against the surface to enhance the sealing effect, but also avoid reducing the negative pressure transmission efficiency due to excessive thickness. The design that the inner diameter of the through hole is 0.5-1mm larger than the inner diameter of the suction hole 304 ensures that the negative pressure generated by the suction hole 304 can be smoothly transmitted to the contact interface with the blank, giving full play to the negative pressure adsorption effect.
