By setting the cooperation of the servo motor, the first hydraulic rod, the second hydraulic rod and the third hydraulic rod, and the flexible adjustment of the telescopic component, it can adjust the position and angle of the clamping component and the adsorption component in multiple dimensions, which is conducive to adapting objects of various shapes and sizes. Whether it is a rectangular, cylindrical or complex shape, it can achieve stable clamping or adsorption, thereby realizing the diversity and flexibility of transfer; secondly, it realizes the dual protection of clamping and adsorption. By setting the clamping component and the adsorption component, the two can work independently or in coordination. The clamping component uses rubber pads and anti-slip strips to provide friction, which is suitable for objects whose surfaces are not easily damaged; and the adsorption component realizes non-destructive adsorption of objects with easily damaged or thin surfaces through the cooperation of suction cups and air pumps.

Especially when transporting smaller objects, the adsorption area can be reduced to improve the stability and accuracy of the suction force, thereby achieving more precise and accurate transfer control of the objects.

That is, the clamping assembly 10 is adjusted by adding an angle dimension through the third hydraulic rod 12, so that the entire clamping work can be more flexibly adapted to the clamping of objects of more shapes.

[0047] The adsorption component 14 includes a suction cup 141 for adsorbing objects. The suction cup 141 is evenly provided with a plurality of circles of adsorption holes 145 surrounding the center of the circle in the radial direction. An isolation ring 146 corresponding to the plurality of circles of adsorption holes 145 is arranged inside the suction cup 141. The suction cup 141 forms a plurality of layers of isolation chambers through the isolation ring 146. The innermost isolation chamber of the suction cup 141 is connected to the air pump 4. An adjustment component 142 for controlling the connection between the plurality of layers of isolation chambers is arranged near the suction cup 141, and is used to adjust the adsorption area of ​​the adsorption component 14.

According to the requirements of the specific object, only the clamping component 10 is involved in the work, or only the adsorption component 14 is involved in the work, or the two are combined to adapt to various working scenarios.

[0048] The specific structure is disclosed below. First, the specific structure of the support assembly 8 is disclosed. Figure 2-Figure 3 As shown, the support assembly 8 includes a support ring 81, and a plurality of brackets 83 are evenly fixedly connected on the four sides of the support ring 81, and the brackets 83 are fixedly connected to the bottom end of the fixed seat 7.

[0049] Next, the specific structure of the telescopic assembly 9 is disclosed, see Figure 2 and Figure 4 As shown, the telescopic assembly 9 includes a fixed ring 91 fixedly connected to the bottom end of the second hydraulic rod 11, and also includes a moving block 92 corresponding to the limit block 82 one by one. The moving block 92 is an equilateral triangle structure, one side of the moving block 92 is perpendicular to the horizontal plane, and the intersection of the vertical side and the horizontal side of the moving block 92 is fixedly connected to the fixed ring 91. A guide groove 93 is provided on the bottom side of the moving block 92, and a slider 94 is slidably connected in the guide groove 93. A slide groove 96 adapted to the width of the moving block 92 is provided in the slider 94. One end of the slider 94 away from the fixed ring 91 is fixedly connected to one end of the telescopic rod 95, and the other end of the telescopic rod 95 passes through the limit block 82 and is slidably connected to the limit block 82.

[0050] It is worth mentioning that an airbag assembly 13 for squeezing and blowing off dust on products and equipment is also provided in the telescopic assembly 9. The airbag assembly 13 includes a first airbag 131 fixedly connected to the support plate 84 and located directly below the second hydraulic rod 11, and the exhaust end of the first airbag 131 is connected to the cleaning hole 86, and also includes a second airbag 132 sleeved on the slider 94; in this way, when the second hydraulic rod 11 telescopes and drives the fixed ring 91 downward, the first airbag 131 will be squeezed and then the equipment and products directly below will be cleaned, and at this time, the hypotenuse of the moving block 92 will also squeeze the second airbag 132, thereby cleaning the clamping assembly 10 next to it.

[0051] Next, the specific structure of the clamping assembly 10 is disclosed, see Figure 5 and Figure 6As shown, the clamping assembly 10 includes a support rod 101, which is rotatably connected to one end of the telescopic rod 95 away from the limit block 82. One end of the third hydraulic rod 12 is rotatably connected to the bracket 83, and the other end is rotatably connected to one end of the support rod 101. The other end of the support rod 101 is fixedly connected to a clamping plate 102, and rubber pads 103 are fixedly provided on the opposite sides of the clamping plates 102. Anti-slip strips 104 are fixedly connected to the rubber pads 103 at equal intervals. A first mounting hole 105 is opened at the geometric center position of the rubber pad 103, and a second mounting hole 106 is opened at the geometric center position of the clamping plate 102. An adsorption assembly 14 is arranged in the second mounting hole 106.

[0052] For further information, see Figure 6-Figure 8 and Fig.10 As shown, the suction cup 141 is fixedly arranged in the first mounting hole 105, the adsorption assembly 14 also includes an outer cylinder 143 fixedly connected to the suction cup 141 and interconnected, the outer cylinder 143 is threadedly connected with a joint assembly 144, and an air guide cylinder 147 is arranged on the outer periphery of the innermost circle of the plurality of isolation chambers, and a filter screen 148 is fixedly arranged at the joint between the air guide cylinder 147 and the suction cup 141 for filtering dust and other garbage; secondly, the joint assembly 144 includes a butt joint 1441, one end of which is fixedly connected to the second mounting hole 106, and the other end is threadedly connected to the outer cylinder 143. The outer tube 143 is connected with the butt joint 1441, and a butt joint 1442 is arranged in the butt joint 1441. A gap matching the thickness of the air cylinder 147 is reserved between the butt joint 1442 and the butt joint 1441. The outer diameter of the butt joint 1442 matches the inner diameter of the air cylinder 147. The air cylinder 147 is used to be inserted into the gap between the butt joint 1442 and the butt joint 1441 and fit with the outer wall of the butt joint 1442. An air suction pipe 1443 is opened at the center of the butt joint 1442, and the air suction pipe 1443 is used to be connected with the air pump 4.

[0053] For further information, see Fig. 9 As shown, an adjustment component 142 is arranged on the top of the outer tube 143, and the adjustment component 142 includes a connecting tube 1421, one end of the connecting tube 1421 passes through a plurality of isolation rings 146 and enters the air guide tube 147, and is communicated with the air guide tube 147, and the other end passes through the rubber pad 103 and is exposed to the outside to form an adjustment part, and the end exposed to the outside is sealed, and the adjustment part is composed of an adjustment rod 1422 fixedly connected to the connecting tube 1421, and the connecting tube 1421 is threadedly connected to the top of the rubber pad 103, and the top of the rubber pad 103 is made of hard material; a plurality of ventilation holes 1423 are opened on the connecting tube 1421, and the distance between the ventilation holes 1423 is adapted to the distance between the plurality of isolation chambers, and the plurality of ventilation holes 1423 are respectively located in each isolation chamber for connecting each isolation chamber.

[0054] It should also be added that the inner diameter of the air guide cylinder 147 is adapted to the distance from the bottom end of the connecting tube 1421 to the topmost air vent 1423, which is used to control the air suction only through the innermost circle isolation chamber formed by the air guide cylinder 147. This ensures that after all the air vents 1423 are adjusted to enter the air guide cylinder 147, only the air guide cylinder 147 can achieve adsorption, so that there will be a minimum adsorption area. It should also be noted that the connection between the connecting tube 1421 and the outer tube 143 is sealed.

[0055] In addition, the front end of the suction cup 141 is lower than the groove formed between the anti-slip strips 104, so that when only the clamping assembly 10 is involved in the work and the object is clamped by clamping or friction, the anti-slip strip 104 will be squeezed and recessed, but will not touch the suction cup 141, preventing damage to the suction cup 141 and ensuring the flatness of its surface.

[0056] Working principle:

[0057] First, the servo motor 3 drives the moving platform 5 to move to the top of the specified object, and then the first hydraulic rod 6 is extended and retracted to drive the fixed seat 7 to move to the top of the object until the clamping assembly 10 directly below the supporting assembly 8 fits with the object. The following is an example of a specific scenario:

[0058] The first scenario: First, if the object to be clamped is a rectangular or cylindrical object, such as a tire outer tyre or wheel hub, or other rectangular decorative objects, etc.; since these objects do not have high requirements on the surface, there is no need to start the air pump 4 to drive the adsorption component 14 to work, and only the clamping component 10 needs to participate in the work; at this time, the third hydraulic rod 12 is driven, and then the clamping angle of the entire clamping plate 102 is adjusted through the connection between the support rod 101 and the third hydraulic rod 12 and the connection between the support rod 101 and the telescopic rod 95, and at the same time, the second hydraulic rod 11 is moved downward or upward to drive the moving block 92 to move, thereby causing the slider 94 to slide in the guide groove 93. Since the guide groove 93 is an inclined groove inclined upward, it causes several sliders 94 to expand outward or contract inward - moving The movable block 92 moves downward, and the slider 94 expands outward; the movable block 92 moves upward, and the slider 94 contracts inward; thereby cooperating with the third hydraulic rod 12 to drive the support rod 101 to adjust the angle to achieve clamping of the object. The figure only takes the example of evenly arranging four groups of clamping components 10 around the support ring 81, and at least two groups of clamping components 10 can be set according to needs; at this time, when a number of rubber pads 103 are attached to the object, the object is clamped by friction or clamping force, and according to the adjustment of the lateral telescopic component 9 and the second hydraulic rod 11 and the angle adjustment of the support rod 101 and the third hydraulic rod 12, the clamping of objects of various shapes can be achieved, not limited to rectangles and cylinders, and slightly heterogeneous or complex objects can also be clamped, but the premise is that the surface of the object is not easily damaged.

[0059] Second scenario: When clamping an object with a vulnerable surface, the entire clamping process is the same as the first scenario above. However, when the rubber pads 103 on the surroundings and the center are in contact with the surface of the object, the clamping is no longer driven, and only the contact is maintained. At this time, the air pump 4 is started to drive the entire adsorption assembly 14 to work, which will drive the air guide cylinder 147 to evacuate air through the suction pipe 1443, and then the suction cup 141 is caused to adsorb the object through the transmission of the connecting pipe 1421. A balanced clamping force is achieved through the adsorption of the surroundings and the center position, and then the object is transferred through the rotating seat 1. However, this process does not squeeze the object, which can protect the object.

[0060] The third scenario: For thinner or softer objects, such as tire inner tubes, the third hydraulic rod 12 and the support rod 101 need to be coordinated according to the first scenario, so that the support rods 101 and the clamping plates 102 are adjusted to a horizontal angle, that is, to ensure that the adsorption surface of the suction cup 141 is perpendicular to the horizontal plane. In this way, the distance between the suction cups 141 can be adjusted with the help of the cooperation of the second hydraulic rod 11 and the telescopic assembly 9 to adapt to the size of the object, and then the first hydraulic rod 6 is moved down until the rubber pad 103 fits the surface of the object, but do not squeeze the object. At this time, the adsorption action according to the second scenario can be performed to achieve balanced adsorption and stabilization of the object from the center to the surroundings, and then the transportation can be achieved.

[0061] The fourth scenario: very small parts, such as wheel hub decorative covers, are small and their surfaces are easily damaged. Therefore, the position of the suction cup 141 can remain unchanged according to the position in the third scenario, but the adsorption area of ​​several suction cups 141 needs to be adjusted to match the size of the object. If the adsorption area is larger than the object, the suction will be unstable and dust will be easily adsorbed. Rotate the adjusting rod 1422 so that the vent hole 1423 in the outer isolation chamber gradually enters the air guide tube 147. This will reduce the adsorption area layer by layer to match the size of the object. Then start the air pump 4 for adsorption. At this time, the adsorption can be carried out with the help of the suction cups 141 around the support ring 81 or the suction cup 141 in the center.

[0062] The fifth scenario: objects with complex shapes, regardless of whether the surface is fragile or not, require both clamping and adsorption to work simultaneously to clamp the object due to the complex shape. However, if the surface is fragile, the participation of the clamping component 10 is reduced, but it plays an auxiliary role. Otherwise, the clamping strength of the clamping component 10 is determined according to the clamping needs, and then the adsorption of the adsorption component 14 is coordinated to realize the transportation of the complex object.

[0063] From the above, it can be concluded that this transfer device can realize the transfer of objects of various shapes, objects with easily damaged surfaces, and thin objects through the adsorption of the adsorption component 14, and the surface adsorption area of ​​the suction cup 141 is adjustable. Therefore, when adsorbing and transferring smaller or thinner objects such as smaller wheel hub decorative covers, the adsorption area of ​​the suction cup 141 can be adjusted according to the volume of the object to adapt it to the smaller object; in addition, the four clamping plates 102 below and around the center position of the support ring 81 are all equipped with rubber pads 103, which can also clamp and transfer basic objects, that is, objects with surfaces that are not easily damaged. At the same time, during the clamping stage, the first airbag 131 and the second airbag 132 can be squeezed to clean the objects and equipment. In addition, the outer cylinder 143 and the joint component 144 are threadedly connected, and the adjustment component 142 and the filter screen 148 are all detachable and washable; thereby effectively solving the problem that when the existing transfer device for the conveyor line is used to transport cylindrical, plate-mounted, tire or easily scratched objects, the traditional clamping or transportation relying on friction cannot achieve damage-free transportation of such objects.
