Description

Technical Field

[0001] This utility model relates to the field of interior parts manufacturing technology, and in particular to a gripping robot for automotive interior parts manufacturing. Background Technology

[0002] Automotive interiors refer to the decorative items used in the decoration and modification of automobiles, such as seat cushions, steering wheel covers, and sun protection films. They involve many aspects of the car's interior. In the production and manufacturing process of interior parts, robotic arms and fixtures are often used to achieve mold taking and mold feeding in order to improve production efficiency.

[0003] A robotic gripper for producing automotive interior parts, disclosed in Chinese Patent Publication No. CN218170435U, involves a motor driving two gripping blocks to approach each other to clamp the object. The two gripping blocks slide within two grooves to prevent them from falling off during sliding. A drive disc rotates within the inner circumference of a fixed block, causing a support rod to rotate, allowing the device to clamp at different angles. However, according to related technologies and existing technologies, in the actual operation of the robotic gripper, if the power source malfunctions or stops supplying power, the gripping force on the workpiece is instantly lost, leading to the workpiece loosening or even falling off, severely affecting the stability and reliability of the clamping. Furthermore, this robotic gripper lacks an effective clamping stroke limitation mechanism, making it prone to excessive clamping stroke during clamping, causing unnecessary damage to the workpiece and affecting its quality and subsequent use. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a gripping robot for the production of automotive interior parts.

[0005] The purpose of this utility model is achieved through the following technical solution: a gripping robot for producing automotive interior parts, comprising a robotic arm, an actuator fixedly provided with a cylinder, a fixed plate fixedly provided on the side of the cylinder away from the robotic arm, two grippers hinged to the fixed plate, the output end of the cylinder extending through the fixed plate between the two grippers, a control component for controlling the opening and closing of the grippers provided at the output end of the cylinder, a limiting component for limiting the maximum stroke of the control component provided on the fixed plate, a self-locking component for locking the position of the control component fixedly provided at the bottom of the limiting component, and an unlocking component for unlocking the self-locking component provided on the self-locking component.

[0008] Preferably, the self-locking assembly includes a locking sleeve fixed to the bottom of the adjusting frame. Two locking tongues are slidably installed inside the locking sleeve. The two locking tongues are symmetrically arranged. Push plates are fixedly provided on opposite sides of the two locking tongues. A second spring is provided on the side of the push plate away from the locking tongue. A locking hook is fixedly provided at the bottom of the drive plate at a position corresponding to the locking sleeve.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0024] like Figures 1 to 6As shown, a gripping robot for producing automotive interior parts includes a robotic arm 1. A cylinder 3 is fixedly mounted on the execution end of the robotic arm 1. A fixed plate 2 is fixedly mounted on the side of the cylinder 3 away from the robotic arm 1. Two grippers 4 are hinged to the fixed plate 2. The output end of the cylinder 3 extends through the fixed plate 2 between the two grippers 4. A control component 6 for controlling the opening and closing of the grippers 4 is provided at the output end of the cylinder 3. A limit component 5 for limiting the maximum stroke of the control component 6 is provided on the fixed plate 2. A self-locking component 7 for locking the position of the control component 6 is fixedly mounted at the bottom of the limit component 5. An unlocking component 8 for unlocking the self-locking component 7 is provided on the self-locking component 7. In use, the robotic arm 1 extends the grippers 4 to the workpiece, and then the cylinder 3... The extension of cylinder 3 pulls the two grippers 4 closer together to clamp the workpiece via the control component 6. When the workpiece is clamped, the control component 6 is locked by the self-locking component 7, keeping the grippers 4 in a clamped state. Even if the power source fails or stops supplying power, a stable clamping force can still be maintained to prevent the workpiece from loosening or falling. When the robotic arm 1 moves the clamped workpiece to the desired position, cylinder 3 is shortened. At this time, the control component 6 will control the self-locking component 7 to automatically release the lock on the control component 6 through the unlocking component 8, so that the two grippers 4 can open and release the workpiece. At the same time, during the clamping process, the limiting component 5 can limit the maximum stroke of the control component 6 to avoid over-clamping and damaging the workpiece.

[0025] like Figures 2 to 5 As shown, the control component 6 includes a slide plate 63 fixed to the output end of the cylinder 3. A connecting sleeve 61 is slidably mounted on the outside of the slide plate 63. A first spring 64 is provided between the slide plate 63 and the connecting sleeve 61. A drive plate 62 is fixedly provided at the bottom of the connecting sleeve 61. Both ends of the drive plate 62 are hinged with connecting rods 65. The two connecting rods 65 are respectively hinged to two grippers 4. When the cylinder 3 extends, it pushes the drive plate 62 toward the locking sleeve 71 through the slide plate 63. During this process, the drive plate 62 pulls the two grippers 4 closer together under the support of the fixed plate 2 through the connecting rods 65 to clamp the workpiece.

[0026] like Figure 2 As shown, the limiting component 5 includes an adjusting frame 51 that is slidably mounted on the fixed plate 2. Two locking bolts 52 are provided between the adjusting frame 51 and the fixed plate 2. The adjusting frame 51 is U-shaped. When clamping, the adjusting frame 51 limits the maximum stroke of the drive plate 62 to prevent the gripper 4 from excessively clamping and damaging the workpiece. At the same time, the adjusting frame 51 is slidably connected to the fixed plate 2. Loosening the locking bolts 52 can change the position of the adjusting frame 51, thereby changing the maximum stroke of the drive plate 62 to adapt to different workpieces.

[0027] like Figure 3 and Figure 4As shown, the self-locking assembly 7 includes a locking sleeve 71 fixed to the bottom of the adjusting frame 51. Two locking tongues 73 are slidably installed inside the locking sleeve 71. The two locking tongues 73 are symmetrically arranged, and push plates 74 are fixedly provided on the opposite sides of the two locking tongues 73. A second spring 75 is provided on the side of the push plate 74 away from the locking tongue 73. A locking hook 72 is fixedly provided at the bottom of the drive plate 62 at the position corresponding to the locking sleeve 71. The opposite ends of the two locking tongues 73 are provided with upward-facing wedge-shaped surfaces. The locking hook 72 is in the shape of an inverted T-shape, and wedge-shaped surfaces that cooperate with the locking tongues 73 are provided on both sides of the bottom. When the workpiece is clamped, the drive plate 62 just contacts the locking sleeve 71. At this time, the locking hook 72 is inserted into the locking sleeve 71 and hooks the locking tongues 73, thereby locking the position of the drive plate 62 through the locking tongues 73, so that the gripper 4 is always in a clamping state. Even if the power source fails or stops supplying power, it can still maintain a stable clamping force and prevent the workpiece from loosening or falling.

[0028] like Figures 3 to 6 As shown, the unlocking assembly 8 includes two unlocking brackets 82 slidably mounted on both ends of the drive plate 62. Each of the two unlocking brackets 82 has a push rod 81 hinged to its top. The push rod 81 is hinged to the slide plate 63. When locked, the bottom of the two unlocking brackets 82 is respectively attached to the inner side of the two push plates 74. When it is necessary to release the workpiece, the cylinder 3 is shortened. At this time, since the drive plate 62 is in the locked state, the shortening of the cylinder 3 will pull the slide plate 63 to compress the first spring 64 and slide upward in the connecting sleeve 61. The slide plate 63 will then push the two unlocking brackets 82 to move in opposite directions through the two push rods 81, so that they push the push plate 74 to compress the second spring 75 and drive the locking tongue 73 to retract, releasing the obstruction of the locking hook 72, thereby automatically unlocking the drive plate 62, so that the two grippers 4 open and release the workpiece.

[0029] The work process is as follows:

[0030] S1: As Figure 1 As shown, during use, the gripper 4 is extended to the workpiece by the robotic arm 1;

[0031] S2: As Figure 2 As shown, the cylinder 3 then extends and pushes the drive plate 62 toward the locking sleeve 71 via the slide plate 63. During this process, the drive plate 62 pulls the two grippers 4 together via the connecting rod 65 to clamp the workpiece under the support of the fixed plate 2.

[0032] S3: As Figure 3 and Figure 4 As shown, when the workpiece is clamped, the drive plate 62 just contacts the locking sleeve 71. At this time, the locking hook 72 is inserted into the locking sleeve 71 and hooks the locking tongue 73, thereby locking the position of the drive plate 62 through the locking tongue 73, so that the gripper 4 is always in the clamping state. Even if the power source fails or stops supplying power, it can still maintain a stable clamping force to prevent the workpiece from loosening or falling off.

[0033] S4: As Figures 1 to 6 As shown, when the robotic arm 1 moves the clamped workpiece to the required position, the cylinder 3 is shortened. At this time, since the drive plate 62 is in a locked state, the shortening of the cylinder 3 will pull the slide plate 63 to compress the first spring 64 and slide upward in the connecting sleeve 61.

[0034] S5: As Figure 5 and Figure 6 As shown, the sliding plate 63 slides in the connecting sleeve 61 and pushes the two unlocking frames 82 to move in opposite directions through the two push rods 81, which pushes the push plate 74 to drive the locking tongue 73 to retract, release the obstruction of the locking hook 72, and automatically unlock the drive plate 62, so that it drives the two grippers 4 to open through the connecting rod 65 and release the workpiece.

[0035] S6: As Figure 2 As shown, during clamping, the adjusting frame 51 limits the maximum stroke of the drive plate 62 through the locking sleeve 71 to prevent the gripper 4 from over-clamping and damaging the workpiece. At the same time, the adjusting frame 51 is slidably connected to the fixed plate 2. By loosening the locking bolt 52, the adjusting frame 51 can drive the locking sleeve 71 to change its position, thereby changing the maximum stroke of the drive plate 62 to adapt to different workpieces.

[0036] The robotic arm 1 and cylinder 3 in this application are known technologies in this field, therefore their specific structures and working principles are not described in detail.

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.
