Description

Technical Field

[0001] This utility model relates to the field of gripper devices, and in particular to a flexible gripper for product assembly. Background Technology

[0002] Grippers are widely used in industrial machining, automated assembly, and logistics sorting. In automated assembly lines, mechanical grippers can automatically pick up parts and achieve automated assembly. Through the automated operation of mechanical grippers, not only can labor costs be reduced, but assembly efficiency and accuracy can also be improved, thereby improving the efficiency and quality of the entire production line. However, traditional assembly grippers still have some drawbacks, such as the inability of a single set of grippers to be adjusted for different products, the need to change grippers of different sizes and accuracies when gripping different products, which increases the cost of equipment for enterprises, and the fact that most of them are rigid mechanical structures, which can easily damage products if the gripping force is not properly controlled, and the gripping error is relatively high when gripping products of different shapes. Utility Model Content

[0003] The purpose of this invention is to provide a flexible gripper for product assembly in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A flexible gripper for product assembly includes a flexible deformable gripping cavity, an inlet / outlet air tube assembly, and gripping claws. The flexible deformable gripping cavity has a gas regulating chamber inside. The inlet / outlet air tube assembly is installed on the top of the flexible deformable gripping cavity and communicates with the gas regulating chamber. Several gripping claws are installed at the bottom of the flexible deformable gripping cavity. The flexible deformable gripping cavity is composed of a funnel-shaped cavity wall, an annular cavity wall connected to the bottom annular edge of the funnel-shaped cavity wall, and a top cover wall connected to the top annular edge of the funnel-shaped cavity wall. A flexible spherical cavity wall is installed on the bottom annular edge of the annular cavity wall.

[0006] Furthermore, several deformations cause the gripping claws to be evenly distributed in a ring shape at the edge of the flexible spherical capsule wall.

[0007] Furthermore, the intake and exhaust pipe assembly consists of an intake pipe and an exhaust sleeve installed at the bottom of the intake pipe. An exhaust pipe connector is connected and installed on the side of the exhaust sleeve, and an intake pipe connector is installed at the top of the intake pipe.

[0008] Furthermore, a cavity vent is provided at the center of the top cover wall, and an internal threaded fitting is installed on the inner side of the cavity vent.

[0009] Furthermore, the outer side of the air intake pipe is provided with a clamping external thread, and two clamping nuts are screwed onto the air intake pipe through the clamping external thread. A top protective edge ring is provided on the top ring edge of the cavity vent hole.

[0010] Furthermore, the gripper consists of a gripper column and a structural hole at the end of the gripper column. The gripping side of the gripper column is provided with an arc-shaped inner groove, and the gripper column is also provided with several anti-slip grooves.

[0011] The beneficial effects are:

[0012] 1. Flexible grippers can adapt flexibly to different products, reducing production line downtime and thus improving production efficiency;

[0013] 2. Because flexible grippers can adapt to a variety of products, companies do not need to purchase multiple grippers to handle different products, thus saving equipment costs;

[0014] 3. Through vacuum negative pressure, the grippers can precisely deform according to the shape of the object being gripped, achieving more precise gripping and handling operations and reducing errors;

[0015] 4. Flexible grippers typically use soft materials, such as silicone, which reduces the safety risks when in contact with the grippers and lowers the possibility of accidental injury.

[0016] 5. It can be applied to various industrial scenarios and has a wide range of applications. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-3 As shown, a flexible gripper for product assembly consists of a flexible deformable gripping bladder 1, an inlet / outlet air tube assembly 2, and a gripping gripper 3.

[0024] The flexible deformable gripping bladder 1 has a gas regulating chamber inside. The inlet and outlet air pipe assembly 2 is installed on the top of the flexible deformable gripping bladder 1 and is connected to the gas regulating chamber. Several gripping claws 3 are installed at the bottom of the flexible deformable gripping bladder 1. There are at least two gripping claws 3, which are used to grip the assembled products. The gripping is mainly driven by the deformation caused by the change of air pressure in the flexible deformable gripping bladder 1. The range of motion can be adjusted according to the change of air pressure to achieve flexible gripping. It is mainly used for gripping toy products.

[0025] The flexible deformable grasping bladder cavity 1 is composed of a funnel-shaped cavity wall 11, an annular cavity wall 15 connected to the bottom annular edge of the funnel-shaped cavity wall 11, and a top cover wall 12 connected to the top annular edge of the funnel-shaped cavity wall 11. A cavity ventilation hole is opened at the center of the top cover wall 12. The cavity ventilation hole is mainly used for connecting the inlet and outlet air pipe assembly 2 to realize the air pressure regulation of the inlet and outlet air.

[0026] A flexible spherical capsule wall 16 is installed on the bottom circumference of the annular cavity wall 15. The flexible spherical capsule wall 16 is made of silicone material. The gas regulating cavity is formed by the flexible spherical capsule wall 16, the funnel-shaped cavity wall 11, the top cover wall 12 and the annular cavity wall 15. The flexible spherical capsule wall 16 is the main deformation structure. The funnel-shaped cavity wall 11, the top cover wall 12 and the annular cavity wall 15 deform less when the internal air pressure changes. Several deformations drive the gripping claws 3 to be evenly distributed in a ring shape at the edge of the flexible spherical capsule wall 16.

[0027] like Figures 1-3 As shown, this utility model also discloses the following more optimized specific structures:

[0028] The air intake and exhaust pipe assembly 2 consists of an air intake pipe 21 and an exhaust sleeve 22 installed at the bottom of the air intake pipe 21. An exhaust pipe connector 25 is connected and installed on the side of the exhaust sleeve 22, and an air intake pipe connector 24 is installed at the top of the air intake pipe 21. They are used to connect to an external power air source to achieve rapid air intake and exhaust and facilitate the adjustment of internal gas.

[0029] An internal threaded fitting 13 is installed on the inner side of the vent hole of the cavity. The bottom end of the exhaust sleeve 22 is provided with a screw joint. The exhaust sleeve 22 is screwed onto the internal threaded fitting 13 through the screw joint, so as to realize the detachable connection between the inlet and outlet air pipe assembly 2 and the flexible deformable grasping bladder cavity 1.

[0030] The outer side of the air intake pipe 21 is provided with a clamping external thread. The air intake pipe 21 is screwed with two clamping nuts 23 through the clamping external thread. The two clamping nuts 23 are used to clamp on the lifting frame and cooperate with the lifting moving frame for clamping. The top circumference of the cavity ventilation hole is provided with a top protective edge ring 14.

[0031] The gripper 3 consists of a gripper post 31 and a structural hole 34 at the end of the gripper post 31. The gripping side of the gripper post 31 is provided with an arc-shaped inner groove 33. The gripper post 31 is also provided with several anti-slip grooves 32 to increase the gripping friction. The arc-shaped inner groove 33 and the structural hole 34 help the gripper 3 to better adapt to deformation and force when gripping the product.

[0032] like Figures 1-3 The flexible gripper shown utilizes the properties of silicone and airbags to grasp and transport objects of different shapes. Through vacuum negative pressure, the gripper can deform according to the shape of the object being grasped, thereby achieving more precise contour-following grasping and transport operations. During operation, it needs to be used in conjunction with components such as a mobile lifting frame and an external air source pump. It is connected to the external air source pump through the air inlet pipe connector 24 and the exhaust pipe connector 25 to realize the air volume regulation inside the gas regulation chamber, and is clamped to the mobile lifting frame through two clamping nuts 23 to achieve grasping and placement.

[0033] When gripping is required, the flexible gripper for product assembly is moved above the product via a movable lifting frame. The lifting operation is started, so that the gripper 3 surrounds the side of the product. By adjusting the air volume, the gas regulating chamber is made to be under negative pressure. The middle position of the flexible spherical capsule wall 16 moves upward and deforms, which drives the gripper 3 to grip the product. After reaching the designated position, the air volume is adjusted to release it, thus achieving flexible gripping.

[0034] It is mainly used in industries such as logistics, automobile manufacturing, and electronics manufacturing, and is particularly effective on production lines that need to handle a variety of products.

[0035] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
