Detailed Implementation

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] In this embodiment, terms such as "first" and "second" are used only to distinguish components with similar structures or functions, and are not used to indicate the connection or installation sequence. Directional terms such as "up," "down," "left," and "right" only correspond to the orientation shown in the accompanying drawings and are unrelated to the orientation in actual use.

[0026] like Figure 1 As shown, the variable-distance suction device of this embodiment includes: a base assembly, a distance adjustment assembly, a cylinder suction assembly, and a servo motor assembly.

[0027] The base assembly has a first base plate 11, a second base plate 12, a slider 17, and a guide rail 18.

[0028] The first base plate 11 serves as the bottom fixing component, and the second base plate 12 is connected and installed on the first base plate 11 according to the hole positions. The second base plate 12 is installed on the side of the first base plate 11.

[0029] The guide rail 18 is fixedly installed on the second base plate 12 according to the hole positions, and the slider 17 is slidably installed on the two guide rails 18 respectively.

[0030] The base assembly also includes a first side plate 10, a second side plate 15, and an outer cover 16, with the first side plate 10 and the second side plate 15 respectively installed on both sides of the first base plate 11.

[0032] In a preferred embodiment, two second base plates 12 are respectively mounted on the upper and lower sides of the first base plate 11. Correspondingly, there are two guide rails 18, which are fixedly mounted on the two second base plates 12, and six sliders 17, which are slidably mounted on the two guide rails 18.

[0033] There are two second connecting plates 6, which are fixedly installed at the upper and lower ends of the third connecting plate 7 respectively. The two second connecting plates 6 are fixedly connected to the two sliders 17 respectively.

[0034] Flange plate 19 and stiffening plate 20 are installed on the first base plate 11 according to the hole positions.

[0035] The distance adjustment assembly includes a lead screw 1, a nut 26, a nut fixing block 2, a connecting block 5, a first bearing seat 3, and a second bearing seat 4.

[0036] like Figure 1 Corresponding to the number of mobile suction components, there are three sets of distance adjustment components.

[0037] The nut 26 is threadedly connected to the lead screw 1, and when the lead screw 1 rotates, it drives the nut 26 to make linear motion on it.

[0038] The distance adjustment assembly also includes a nut fixing block 2, which is fixedly connected to the nut 26, and a connecting block 5 is fixedly connected to the nut fixing block 2. In some embodiments, the connecting block 5 can also be directly fixedly connected to the nut 26, thereby saving the structure of one nut fixing block 2.

[0039] The first bearing housing 3 and the second bearing housing 4 are respectively fitted onto both ends of the lead screw 1 to maintain the position of the lead screw 1.

[0040] The second synchronous pulley 21 is mounted on one end of the lead screw 1 of the distance adjustment assembly. The complete set of components is installed on the corresponding positions of the first base plate 11, the first side plate 10, and the second side plate 15.

[0041] like Figure 2 The two ends of the lead screw 1 are rotatably mounted between the first bearing housing 3 and the second bearing housing 4. The first bearing housing 3 is mounted on the corresponding position of the first base plate 11. The second bearing housing 4 is mounted on the first side plate 10 or the second side plate 15 according to the mounting direction of the motor and the synchronous pulley.

[0042] There are two types of cylinder suction assemblies: fixed cylinder suction assemblies and movable cylinder suction assemblies. In this embodiment, there is one set of fixed cylinder suction assemblies and three sets of movable cylinder suction assemblies.

[0043] like Figure 1 , Figure 4 and Figure 5 As shown, the movable cylinder suction assembly has a second connecting plate 6, a third connecting plate 7, a cylinder 23, and a suction cup 24.

[0044] The second connecting plate 6 is fixedly connected to the slider 17, the third connecting plate 7 is fixedly connected to the second connecting plate 6, the cylinder 23 is fixedly connected to the side of the third connecting plate 7, and the suction cup 24 is fixedly sleeved in the corresponding hole of the cylinder 23; the cylinder 23 is installed on the fifth connecting plate 13 and the third connecting plate 7, and then installed together on the fourth connecting plate 14 and the second connecting plate 6, and then connected to the second base plate 12 and the slider 17 according to the hole positions.

[0045] The suction cup 24 is fitted into the connection hole of the cylinder 23. The cylinder 23 drives the suction cup 24 to move up and down. In some embodiments, the suction cup 24 is connected to an external suction device via a flexible hose, which will not be described in detail here.

[0046] Two second connecting plates 6 are respectively installed at the upper and lower ends of the third connecting plate 7. The upper and lower second connecting plates 6 are fixedly installed on the slider 17. Thus, driven by the distance adjustment component, they move along the guide rail 18.

[0047] like Figure 2 As shown, the connecting block 5 has a convex shaft, and the third connecting plate 7 has a shaft hole that engages with the convex shaft of the connecting block 5. This causes the nut 26 of the distance adjustment assembly to move the movable cylinder suction device horizontally.

[0048] like Figure 1 As shown, the fixed cylinder suction device is located on the far right of the diagram. Its position is fixed and it does not need to be connected to the distance adjustment component. It serves as the zero point when the moving cylinder suction device moves. Of course, in some embodiments, the fixed cylinder suction device may not be provided, and the distance adjustment is performed by the moving cylinder suction device connected to the distance adjustment component.

[0049] like Figure 5 As shown, the fixed cylinder suction device includes a fifth connecting plate 13, a fourth connecting plate 14, a cylinder 23, and a suction cup 24. The fifth connecting plate 13 is mounted on the fourth connecting plate 14 and is fixedly connected to the second base plate 12. Since the fixed cylinder suction device does not need to move, its fourth connecting plate 14 is directly fixedly connected to 12 and not connected to the slider 17. The structure of the fourth connecting plate 14 is similar to... Figure 4 The second connecting plate 6 of the movable cylinder suction device shown has a different structure; it is L-shaped and narrower to reduce the size of the device.

[0050] In the fixed cylinder suction device, the fifth connecting plate 13 is installed on the fourth connecting plate 14, the cylinder 23 is installed on the fifth connecting plate 13, the suction cup 24 is inserted into the corresponding hole of the cylinder 23, and the whole assembly is then installed together on the second base plate 12 on both sides according to the hole positions.

[0051] The first group consists of fixed cylinder suction cups, as they do not need to be moved. The following three groups are movable cylinder suction cups, and the spacing between them can be adjusted.

[0052] like Figure 1 As shown, corresponding to the number of movable cylinder suction devices, there are six sliders 17. Every three sliders 17 are fitted into a guide rail 18 and then installed on the second base plate 12. They are then fixed together on the upper and lower sides of the first base plate 11.

[0053] The first side plate 10 and the second side plate 15 are installed at opposite ends of the first base plate 11 according to the hole positions. There are two stiffening plates 20, one end of which is connected to the flange plate 19, and then they are installed together on the first base plate 11.

[0054] The servo motor assembly includes a servo motor 8, a first synchronous pulley 9, a second synchronous pulley 21, and a synchronous belt 22.

[0055] The first synchronous pulley 9 is mounted on the shaft of the servo motor 8, the second synchronous pulley 21 is mounted on the lead screw 1, and the synchronous belt 22 is sleeved on the first synchronous pulley 9 and the second synchronous pulley 21.

[0056] like Figure 1 As shown, the servo motor assembly in this embodiment includes three servo motors 8, which are respectively mounted on the first side plate 10 and the second side plate 15. Two servo motors 8 are mounted on one side, and the remaining servo motor 8 is mounted on the other side. The first side plate 10 is equipped with two servo motors 8, and the second side plate 15 is equipped with one servo motor 8 to ensure a compact space. The corresponding synchronous pulleys and synchronous belts are installed in the aforementioned relative positions.

[0057] In other embodiments, a corresponding number of servo motors 8 are provided for different numbers of movable cylinder suction cups, and they are preferably staggered to reduce the size of the device.

[0058] The cylinder suction assembly in this embodiment has three sets of movable cylinder suction devices, which are respectively connected to three servo motors 8 via synchronous belt 22, lead screw 1, nut 26, nut fixing block 2, and connecting block 5.

[0059] Work process:

[0060] 1. The fixed cylinder suction device is installed on one side of the clamp, serving as the fixed position of the suction device, or the zero position. In the initial state, the moving suction device is arranged close to the fixed cylinder suction device.

[0061] 2. Based on the size of the object, the fixed-position suction cup is set to zero position, and the three sets of moving suction cups are pulled apart by servo motor 8 to a position where they can suck up the object.

[0062] 3. Then the cylinder 23 moves downward, driving the suction cup 24 to move and suck up the object.

[0063] 4. At this time, cylinder 23 moves upward to lift the object, and the entire fixture performs a transfer motion to move the object to the required workstation.

[0064] When it is necessary to adjust the interval between the various moving suction devices, the servo motor 8 drives the distance adjustment component to move according to the specific spacing, pulling the three sets of moving suction devices to the predetermined position.

[0065] Then, cylinder 23 moves downward, driving suction cup 24 to move, and after reaching the corresponding position, it releases the object as required.

[0066] Once the entire fixture completes one cycle, it returns to the starting position to perform the next set of movements.

[0067] Thus, the suction cup, through the action of cylinders and motors, moves objects to the required workstations as needed, completing the transfer and pulling of various goods.

[0068] In summary, this variable-pitch suction device achieves free adjustment of the spacing between the moving cylinder suction components by controlling the movement of each servo motor, thereby enabling the suction of various objects of different sizes and meeting user needs.
