[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. 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.
[0024] This utility model provides, for example Figures 1-4 The illustrated flexible pick-and-place mechanism for line forming with adjustable spacing includes a base plate 1 and multiple guide rails 2 mounted on the upper outer wall of the base plate 1.
[0025] Multiple front and rear drive cylinders 3 are equidistantly arranged between the upper outer walls of the two guide rails 2. A left and right drive cylinder 10 is located near the right side of the upper outer wall of the base plate 1 to drive the multiple front and rear drive cylinders 3 to move laterally. Flexible grippers 5 are located on the rear side of each of the multiple front and rear drive cylinders 3 to pick up and place linear products. When a specific area needs to be picked up or placed, the left and right drive cylinders 10 are activated, pushing the guide rails 2 on the base plate 1, causing the front and rear drive cylinders 3 to move to the left or right as a whole. This lateral movement ensures that the flexible grippers 5 can reach the required position to pick up or place the product. The position of the flexible pick-and-place grippers 5 can be controlled by rotating the adjusting bolts to coordinate with the positions of the front and rear drive cylinders 3. Depending on the size of the product, equal or variable distance clamping can be achieved to ensure adaptability to linear products of various sizes. After the flexible pick-and-place grippers 5 reach the target product position, the front and rear drive cylinders 3 activate the flexible pick-and-place grippers 5, which will close to clamp the product. This action is achieved by the air pressure control of the cylinders, which can quickly and accurately complete the clamping task. After the pick-and-place operation is completed, the flexible pick-and-place grippers 5 will open under the control of the cylinders to release the product.
[0026] like Figure 1 and Figure 2 As shown, a spacing adjustment cylinder 9 is fixedly connected to the upper outer wall of the base plate 1, and a spacing adjustment bolt 8 is provided on the right side of the spacing adjustment cylinder 9 to control the spacing between the two flexible pick-and-place grippers 5.
[0027] During the pick-and-place process, the air cylinder changes the air pressure to change the distance between the two flexible pick-and-place clamps 5. When the air pressure in the air cylinder increases, the flexible pick-and-place clamps 5 will open outward. When the air pressure decreases, the clamps will close. This process allows the clamps to adapt to different sizes of workpieces, improving the flexibility of pick-and-place. The adjusting bolt is mainly used for fine adjustment of the distance between the two flexible pick-and-place clamps 5.
[0028] As shown in Figure 1 , the upper end outer wall of the base plate 1 is provided with a limiting assembly 7 near the left side to limit the maximum transverse movement distance of the front and rear driving air cylinders 3.
[0029] The limiting assembly 7 is arranged on the left side of the upper end outer wall of the base plate 1, responsible for limiting the maximum transverse movement distance of the front and rear driving air cylinders 3, ensuring that the air cylinder does not exceed the predetermined limit during operation, avoiding mechanical damage.
[0030] As shown in Figure 1 , the upper end outer wall of each of the plurality of front and rear driving air cylinders 3 is fixedly connected with a push plate 6, and the upper end outer wall of each of the plurality of push plates 6 is fixedly connected with a fixed frame 4 to limit the position of the flexible pick-and-place clamp 5. The inside of the plurality of fixed frames 4 is provided with a spring floating mechanism to realize flexibility and prevent linear bending.
[0031] The action of the front and rear driving air cylinders 3 is conducted through the push plate 6, driving the fixed frame 4 and the flexible pick-and-place clamp 5 to move in the front and rear directions. When the flexible pick-and-place clamp 5 clamps the product, the internal spring floating mechanism makes the clamp have a certain flexibility through the compression or stretching of the spring. The spring floating mechanism includes a spring, a support frame and a guide device. The spring is used to bear and distribute the force applied when the clamp clamps the article, ensuring that it can quickly adapt to changes in the shape of the article during pick-and-place. The support frame is used to provide the fixed position of the spring, ensuring that the structure will not be damaged due to misoperation during clamping. The guide device can maintain the stability of the clamp during movement, ensuring that the action of the spring does not cause the clamp to deviate from the predetermined path.
[0032] As shown in Figure 2 , when the pitch adjusting bolt 8 is rotated clockwise, the two flexible pick-and-place clamps 5 are controlled to approach each other. When the pitch adjusting bolt 8 is rotated counterclockwise, the two flexible pick-and-place clamps 5 are controlled to separate.
[0033] When it is necessary to adjust the distance between the two flexible pick-and-place clamps 5, the pitch adjusting bolt 8 can be rotated in different directions clockwise or counterclockwise to control the flexible pick-and-place clamps 5 to adjust the distance between them flexibly to adapt to the demand parameters for adjustment.
[0034] As shown in Figure 1As shown, sliders 11 are fixedly connected to the upper outer walls of multiple front and rear drive cylinders 3 to guide the direction of push plates 6, and grooves 14 are opened inside the lower outer walls of multiple push plates 6.
[0035] The slider 11 is fixedly connected to the upper outer wall of the front and rear drive cylinders 3, guiding the movement direction of the push plate 6 and ensuring its linear movement.
[0036] like Figure 1 As shown, a limiting chain b13 is fixedly connected between multiple front and rear drive cylinders 3 and guide rail 2, and a limiting chain a12 is fixedly connected between multiple push plates 6 and front and rear drive cylinders 3. A connecting block 16 is fixedly connected between one end of multiple limiting chains a12 and the front and rear drive cylinders 3 and between the front and rear drive cylinders 3 and the limiting chain b13. Fixing holes 15 are opened inside the upper outer walls of multiple push plates 6 and front and rear drive cylinders 3.
[0037] Limit chain a12 restricts the range of motion of push plate 6 in the forward and backward movement to prevent it from moving too far. Limit chain b13 increases the range of motion of front and rear drive cylinder 3 when it moves left and right to achieve a specific motion trajectory. Multiple fixing holes 15 allow push plate 6 to be flexibly installed at any position on front and rear drive cylinder 3 with the help of external fixing screws.
[0038] The implementation principle of this embodiment is as follows: When a specific area needs to be picked up or placed, the left and right drive cylinders 10 are activated. By pushing the guide rail 2 on the base plate 1, the front and rear drive cylinders 3 move to the left or right as a whole. This lateral movement ensures that the flexible pick-and-place gripper 5 can reach the required position to pick up or place the product. By rotating the adjusting bolt to coordinate with the position of the front and rear drive cylinders 3, the distance between the two flexible pick-and-place grippers 5 can be controlled. Depending on the size of the product, equal or variable distance clamping can be achieved to ensure that it can adapt to linear products of various sizes. After the flexible pick-and-place gripper 5 reaches the target product position, the front and rear drive cylinders 3 activate the flexible pick-and-place gripper 5. The flexible pick-and-place gripper 5 will close to clamp the product. This action depends on the air pressure control of the cylinder, which can quickly and accurately complete the clamping task. After the pick-and-place operation is completed, the flexible pick-and-place gripper 5 will open under the control of the cylinder to release the product.
[0039] 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.
