Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically a flexible gripper for a robot arm used for transporting automobile roofs. Background Technology

[0002] The flexible gripper of the automotive roof handling robot is a device specifically designed for handling and securing automotive roofs of various shapes and sizes. It can adaptively adjust to the roof's contours, using flexible materials or deformable structures to tightly conform to the roof surface, ensuring the roof remains stable and does not slip during handling. This reduces damage to the roof, improves production efficiency and automation, making it an indispensable tool on automotive manufacturing production lines.

[0003] The invention disclosed in CN107472875B provides an automated flexible gripper for handling automobile roofs, belonging to the technical field of "automobile manufacturing." The protected claim states: "It includes symmetrically arranged left and right longitudinal beams, with a crossbeam structure vertically connected between the left and right longitudinal beams; the crossbeam structure includes a crossbeam with a transverse groove at its top, a dual-output shaft transverse drive motor located in the middle of the transverse groove, a right-hand lead screw connected to the left output shaft of the transverse drive motor, and a left-hand lead screw connected to the right output shaft of the transverse drive motor; both the right-hand and left-hand lead screws are equipped with corresponding lead screw nut sliders, and each lead screw nut slider is equipped with a suspension beam, with a negative pressure suction cup on the suspension beam. The crossbeam structure is slidably connected to the left and right longitudinal beams, allowing the crossbeam structure to move longitudinally on the left and right longitudinal beams. This invention is applicable to the handling of automobile roofs of different models, has strong load-bearing capacity, and a wide range of applications."

[0004] While this device is suitable for handling car roofs of different models, the different curvatures of the car roofs at different locations require the suction cups to be adjusted accordingly to adhere tightly to the car roof. Furthermore, using suction cups for adsorption can easily lead to accidents, causing the car roof to fall and be damaged. Therefore, we propose a flexible gripper for a car roof handling robot. Utility Model Content

[0005] The purpose of this invention is to provide a flexible gripper for a robotic arm used for transporting car roofs, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flexible gripper for a robot arm used for transporting car roof covers includes:

[0008] An inner base frame has two grooves at its bottom, and an outer base frame is fixedly connected to the inner base frame.

[0009] An adsorption assembly is provided at the bottom of the inner base frame, and a suction cup is provided inside the adsorption assembly for adsorbing the car roof.

[0010] A fixing assembly, disposed at the bottom of the inner base frame, is used to fix the roof cover; the fixing assembly includes:

[0011] The base frame is fixedly connected to the bottom of the inner base frame, and the base frame has an elongated groove and two limiting grooves inside;

[0012] The second hydraulic rod is fixedly connected to the top of the inner base frame, and the drive end of the second hydraulic rod extends into the long groove;

[0013] The lifting block is fixedly connected to the drive end of the second hydraulic rod, and the two sides of the lifting block are limited and slidably within two limiting grooves.

[0014] A fixing plate is fixedly connected to one end of the lifting block.

[0016] The motor is fixedly connected in the groove, and both drive ends of the motor are fixedly connected to lead screws, the ends of the two lead screws are rotatably connected in the groove.

[0017] The two movable blocks are both limited to slide within the groove, and the two movable blocks are respectively threadedly connected to two lead screws;

[0018] The first hydraulic rod, two first hydraulic rods are respectively fixedly connected to the bottom of two moving blocks, the driving end of each of the two first hydraulic rods is rotatably connected to an adapter, and the bottom of each of the two adapters is rotatably connected to a suction cup;

[0019] The suction device consists of two suction devices, each fixedly connected to the bottom of two movable blocks. The suction end of each suction device is fixedly connected to a connecting tube, and the bottom end of each connecting tube is connected to a suction cup.

[0020] Preferably, the adsorption components are set to two sets, and the two sets of adsorption components are distributed at both ends of the bottom of the inner base frame in a symmetrical arrangement.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. By setting up the adsorption assembly, two sets of motors are started. The motors drive the two lead screws to rotate synchronously in the same direction. Since the threads of the two lead screws are opposite, they will drive the two moving blocks to move relative to or in opposite directions, that is, drive the two suction cups to move relative to or in opposite directions. This is suitable for car roofs of different sizes. At the same time, the two first hydraulic rods are started to drive the two suction cups to rise and fall. When the suction cups are pressed against the car roof, their curvature will drive the suction cups to rotate through the adapter. By raising, lowering and rotating the suction cups, the suction cups can be made to adhere to car roofs with different curvatures.

[0026] 2. After the initial adsorption and fixation by setting the fixing components, the two sets of second hydraulic rods are activated. The second hydraulic rods drive the lifting block to rise and fall in the long groove through the limit groove, and synchronously drive the fixing plate to rise and fall. The synchronous rise and fall of the two sets of fixing plates can fix the roof cover and prevent the roof cover from falling off during the movement due to suction cup failure.

Detailed Implementation

[0032] 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.

[0033] Example 1

[0034] like Figure 1-4 As shown, in this embodiment, a flexible gripper for a car roof handling robot includes: an inner base frame 1, an adsorption component 2, and a fixing component 3. The bottom of the inner base frame 1 has two grooves 11. An outer base frame 12 is fixedly connected to the inner base frame 1. The outer base frame 12 and the inner base frame 1 are fixedly connected. The outer base frame 12 is used to reinforce the structure.

[0035] In this embodiment, the adsorption assembly 2 includes a motor 21, moving blocks 22, first hydraulic rods 23, and a suction device 24. The motor 21 is fixedly connected to the groove 11, and both drive ends of the motor 21 are fixedly connected to lead screws 211, the ends of the two lead screws 211 being rotatably connected to the groove 11. The two moving blocks 22 are both limited and slidably within the groove 11, and the two moving blocks 22 are respectively threadedly connected to the two lead screws 211. The two first hydraulic rods 23 are respectively fixedly connected to the bottom of the two moving blocks 22, and the two first hydraulic rods 23... Both drive ends are rotatably connected to adapter seats 231, and the bottom of both adapter seats 231 is rotatably connected to suction cups 232; two suction devices 24 are fixedly connected to the bottom of the two moving blocks 22 respectively, and the suction ends of the two suction devices 24 are fixedly connected to connecting pipes 241. The bottom ends of the two connecting pipes 241 are respectively connected to the two suction cups 232. By suctioning through the suction devices 24 and the connecting pipes 241 connected to the suction cups 232, the roof can be adsorbed and fixed. It should be noted that the suction device 24 is existing technology and will not be described in detail.

[0036] In this embodiment, the motor 21 is bidirectionally driven, and the threads of the two lead screws 211 are opposite. The motor 21 drives the two lead screws 211 to rotate synchronously in the same direction. Since the threads of the two lead screws 211 are opposite, they will drive the two moving blocks 22 to move relative to or in opposite directions.

[0037] In practice, two sets of motors 21 are started. The motors 21 drive the two lead screws 211 to rotate synchronously in the same direction, which drives the two suction cups 232 to move relative to each other and in opposite directions. This is suitable for roofs of different sizes. At the same time, the two first hydraulic rods 23 are started, which drive the two suction cups 232 to rise and fall. When the suction cups 232 are pressed against the roof, their curvature will drive the suction cups 232 to rotate through the adapter 231. By raising and lowering and rotating the suction cups 232, the suction cups 232 can be made to adhere to roofs of different curvatures.

[0038] Example 2

[0039] Based on Embodiment 1, a fixing component 3 is provided to prevent the roof from falling off.

[0040] like Figure 4As shown, in this embodiment, the fixing component 3 includes a base frame 31, a second hydraulic rod 32, a lifting block 33, and a fixing plate 34. The base frame 31 is fixedly connected to the bottom of the inner base frame 1, and the base frame 31 has an elongated groove 311 and two limiting grooves 312. The second hydraulic rod 32 is fixedly connected to the top of the inner base frame 1, and the driving end of the second hydraulic rod 32 extends into the elongated groove 311. The lifting block 33 is fixedly connected to the driving end of the second hydraulic rod 32, and the two sides of the lifting block 33 are limited and slid within the two limiting grooves 312. The fixing plate 34 is fixedly connected to one end of the lifting block 33, and the position of the fixing plate 34 is always lower than the position of the suction cup 232, so that the roof can be fixed between the adsorption component 2 and the fixing component 3.

[0041] In practice, after initial adsorption and fixation, the two sets of second hydraulic rods 32 are activated. The second hydraulic rods 32 drive the lifting block 33 to rise and fall within the long groove 311 through the limit groove 312, and simultaneously drive the fixing plate 34 to rise and fall. The two sets of fixing plates 34 rise and fall synchronously, which can fix the roof and prevent the roof from falling off due to the failure of the suction cup 232 during movement.

[0042] Working principle: First, the car roof is placed between the adsorption assembly 2 and the fixing assembly 3 via an external device. Then, two sets of motors 21 are started. The motors 21 drive the two lead screws 211 to rotate synchronously in the same direction. Since the threads of the two lead screws 211 are opposite, they will drive the two moving blocks 22 to move relative to or in opposite directions, that is, drive the two suction cups 232 to move relative to or in opposite directions. This is suitable for car roofs of different sizes. At the same time, the two first hydraulic rods 23 are started, which drive the two suction cups 232 to rise and fall. When the suction cups 232 are pressed against the car roof, their curvature will drive the suction cups 232 through the adapter. 231 rotates, and by lifting and rotating the suction cup 232, the suction cup 232 can be made to adhere to the roof with different curvatures. Then, the suction cup 232 is connected to the suction device 24 and the connecting pipe 241 for suction, which can adsorb and fix the roof. After the initial adsorption and fixation are achieved, the two sets of second hydraulic rods 32 are activated. The second hydraulic rods 32 drive the lifting block 33 to rise and fall in the long groove 311 through the limit groove 312, and simultaneously drive the fixing plate 34 to rise and fall. The two sets of fixing plates 34 rise and fall synchronously, which can fix the roof and prevent the roof from falling off if the suction cup 232 fails during the movement.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
