Description

Technical Field

[0001] The utility model relates to the field of food production equipment, in particular to an adjustable-distance gripper for food processing and production. Background Art

[0002] The gripper for food processing and production is an end effector at the end of a robotic arm used in an automated food production line. Its main function is to grasp, move and place various food products during food processing, packaging, handling or palletizing.

[0003] The existing adjustable-distance gripper for food processing and production is usually installed on a robotic arm, and then the product is grasped by the gripper. However, the current gripper can only adjust the distance between the left and right of the gripper, and can only be used for placing square products such as cartons, and cannot grasp products of different shapes, which is rather inconvenient.

[0004] Therefore, it is necessary to design an adjustable-distance gripper for food processing and production that can adjust the height of the connecting gripper and the distance between the front, back, left and right sides of the connecting gripper, so as to facilitate adapting to products of different sizes and shapes and improve the flexibility of using this device. Summary of the Utility Model

[0005] In order to overcome the shortcomings that the existing adjustable-distance gripper for food processing and production can only adjust the distance between the left and right of the gripper, can only be used for placing square products such as cartons, and cannot grasp products of different shapes, the utility model provides an adjustable-distance gripper for food processing and production that can adjust the height of the connecting gripper and the distance between the front, back, left and right sides of the connecting gripper, so as to facilitate adapting to products of different sizes and shapes and improve the flexibility of using this device.

[0006] The technical implementation solution of the utility model is: an adjustable-distance gripper for food processing and production, which includes a connecting frame, a driving component, connecting brackets, rotating frames, cylinders, connecting grippers and extension columns. A driving component is arranged at the front part of the connecting frame. Connecting brackets are slidably connected to the left and right parts of the connecting frame. Rotating frames are rotatably connected to the connecting brackets. Cylinders are connected to the upper parts of the connecting brackets. The telescopic ends of the cylinders are rotatably connected to the adjacent rotating frames respectively. Two front and rear extension columns are slidably connected to the lower parts of the rotating frames. A plurality of connecting grippers are slidably connected to the extension columns, and a plurality of connecting grippers are also slidably connected to the interiors of the rotating frames.

[0007] Optionally, the driving component includes a motor and a bidirectional lead screw. The motor is connected to the right side at the front part of the connecting frame. The output shaft of the motor is connected with the bidirectional lead screw. The bidirectional lead screw is rotatably connected to the connecting frame. The connecting brackets are all threadedly connected to the bidirectional lead screw.

[0008] Optionally, a plurality of mounting holes are formed in the middle of the connecting frame.

[0009] Optionally, the connecting claws are all L-shaped.

[0010] Optionally, it further includes fixing screws. Multiple fixing screws are threadedly connected to both the extension post and the rotating frame, and the fixing screws are all in contact with the adjacent connecting claws.

[0011] Optionally, it further includes a guiding clamping plate and a spring. The guiding clamping plate is slidably connected to the middle and lower part of the connecting frame, and multiple springs are connected between the guiding clamping plate and the connecting frame.

[0012] The beneficial effects of the present utility model are as follows: 1. By moving some of the connecting claws downward according to requirements, then rotating and tightening the fixing screws, then moving the extension post outward, and then moving through the connecting bracket to drive the connecting claws to move, the present utility model can adjust the height of the connecting claws and the distances between the front, rear, left, and right sides of the connecting claws, facilitating adaptation to products of different sizes and shapes and improving the flexibility of using this device.

[0013] 2. By starting the air cylinder to drive the rotating frame to rotate, the connecting claws hold the product tightly, causing the guiding clamping plate to move upward, and the spring contracts and then rebounds to fix the product, achieving the effect of being able to fix the product and prevent the product from detaching from the connecting claws.

Detailed Embodiments

[0018] The following is only a preferred embodiment of the present utility model and does not limit the protection scope of the present utility model accordingly.

[0019] An adjustable-distance gripper for food processing and production, as Figures 1 - 3As shown in the figure, it includes a connecting frame 1, a driving component, a connecting bracket 4, a rotating frame 5, a cylinder 6, fixing screws 7, connecting claws 71, an extension column 8, a guiding clamping plate 9, and a spring 10. There are eight mounting holes in the middle of the connecting frame 1 for easy installation. A driving component is provided at the front of the connecting frame 1. The left and right parts of the connecting frame 1 are both slidably connected with connecting brackets 4. The connecting brackets 4 are both rotatably connected with rotating frames 5. The upper parts of the connecting brackets 4 are both connected with cylinders 6. The cylinders 6 are both L-shaped. The telescopic ends of the cylinders 6 are both rotatably connected with the adjacent rotating frames 5. The lower parts of the rotating frames 5 are both slidably connected with two front and rear extension columns 8. Five connecting claws 71 are slidably connected to the extension columns 8. Five connecting claws 71 are also slidably connected inside the rotating frames 5. Five fixing screws 7 are threadedly connected to both the extension columns 8 and the rotating frames 5. The fixing screws 7 are all in contact with the adjacent connecting claws 71. The middle and lower part of the connecting frame 1 is slidably connected with a guiding clamping plate 9. Eleven springs 10 are connected between the guiding clamping plate 9 and the connecting frame 1.

[0020] As Figure 1 shown, the driving component includes a motor 2 and a bidirectional lead screw 3. The motor 2 is connected to the right side of the front part of the connecting frame 1. The output shaft of the motor 2 is connected with the bidirectional lead screw 3. The bidirectional lead screw 3 is rotatably connected with the connecting frame 1. The connecting brackets 4 are all threadedly connected with the bidirectional lead screw 3.

[0021] When using this device, first install the connecting frame 1 on the robotic arm through the mounting holes, then start the cylinder 6 to drive the rotating frame 5 to rotate, so that the connecting claws 71 hold the product tightly, making the guiding clamping plate 9 move upward. After the spring 10 contracts and rebounds, it fixes the product, thus being able to fix the product and prevent the product from detaching from the connecting claws 71. When it is necessary to grasp different products, some connecting claws 71 can be moved downward according to requirements, then rotate and tighten the fixing screws 7 to fix the connecting claws 71. Then move the extension column 8 outward, and then start the motor 2 to drive the bidirectional lead screw 3 to rotate, so that the connecting brackets 4 move under the action of the thread, driving the connecting claws 71 to move. Thus, the height, width, and length of the grasping by the connecting claws 71 can be adjusted, facilitating adaptation to products of different sizes and shapes and improving the flexibility of using this device.
