Description

Technical Field

[0001] This utility model relates to the technical field of egg sorting equipment, and in particular to a mechanical gripper for egg trays used in egg sorting. Background Technology

[0002] In large-scale egg sorting production, automated egg tray gripping is a core step in the feeding process. Currently, most existing mechanical grippers for egg trays use rigid clamping structures, which have the following drawbacks: When the surface of an egg tray is smooth (such as a plastic tray) or softened by moisture (such as a paper tray), the egg tray is prone to slipping during lifting and lateral movement due to insufficient friction. This not only affects the feeding efficiency but may also cause the eggs to break. Egg trays have poor protective performance. To improve clamping force, some grippers use hard metal clamping arms that directly contact the egg tray. If the clamping force is too strong, it will squeeze the edge of the egg tray and cause deformation. If the clamping force is too weak, it will not be able to meet the requirements for stable gripping. It is difficult to balance the contradiction between clamping force and egg tray protection. Existing grippers are mostly integrated with specific feeding devices, with fixed installation structures, which cannot flexibly adapt to different models of egg tray feeding devices. Replacement or repair requires complete disassembly, resulting in high maintenance costs. Existing grippers rely on friction when holding egg trays, which can easily lead to gripping failures.

[0003] Therefore, there is an urgent need to design a mechanical gripper that balances clamping stability with pallet protection, in order to solve the pain points of existing grippers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mechanical gripper for egg sorting trays, which solves the problems mentioned in the background section.

[0005] The technical solution of this utility model is as follows: A mechanical gripper for sorting egg trays includes a mechanical gripper assembly comprising a mounting base, a clamping drive, two clamping arms, anti-slip pads, and piercing pins. The clamping drive is fixed to the mounting base. The middle portions of the two clamping arms are hinged to one end of the mounting base, and the ends of the two clamping arms are hinged to the output end of the clamping drive. Anti-slip pads are mounted on opposite sides of the two clamping arms. The piercing pins are disposed on the underside of the anti-slip pads, with the tips of the piercing pins on the two clamping arms facing each other. The clamping drive can drive the two clamping arms to rotate in opposite directions.

[0006] Furthermore, the anti-slip pad is made of wear-resistant elastic silicone material.

[0007] Furthermore, the plurality of puncture nails are evenly distributed along the width direction of the anti-slip pad.

[0008] Furthermore, the puncture nail is made of stainless steel.

[0009] Furthermore, the clamping drive is a clamping arm cylinder, the cylinder body of the clamping drive is fixed at the center position of the mounting base, and the piston inside the cylinder is hinged to the two clamping arms through a pin.

[0010] Furthermore, the mounting base consists of two symmetrically arranged clamping plates, which are fixed together by bolts to clamp and fix the clamping drive component.

[0011] Furthermore, the outer walls of the two mounting bases are provided with multiple mounting holes, which are used for detachable connection with the egg tray feeding device by bolts.

[0012] Compared with the prior art, the beneficial effects of the technical solution provided by this utility model are as follows: the clamping arm is opened and closed by the clamping drive component to clamp the egg tray; the anti-slip pad can increase the friction and buffer the clamping force with the egg tray; the piercing nail can be inserted into the egg tray for secondary fixation, making the clamping more stable.

Detailed Implementation

[0014] 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, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0015] like Figure 2-3As shown, a mechanical gripper for sorting egg trays includes a mechanical gripper assembly 25. The mechanical gripper assembly 25 includes a mounting base 2501, a clamping drive component 2502, two clamping arms 2503, an anti-slip pad 2504, and a piercing pin 2505. The clamping drive component 2502 is fixed to the mounting base 2501. The middle portions of the two clamping arms 2503 are hinged to one end of the mounting base 2501, and the ends of the two clamping arms 2503 are connected to the clamping drive component 2502. The output end is hinged; anti-slip pads 2504 are installed on the opposite sides of the two clamping arms 2503; the piercing nails 2505 are located on the lower side of the anti-slip pads 2504, and the tips of the piercing nails 2505 on the two clamping arms 2503 are arranged facing each other; the clamping drive 2502 can drive the two clamping arms 2503 to rotate in opposite directions, so that the anti-slip pads 2504 fit against the arched part of the egg tray, and the piercing nails 2505 pierce into the arched part of the egg tray, thereby clamping or releasing the egg tray.

[0016] Specifically, the mounting base 2501 is generally rectangular, and consists of two symmetrically arranged clamping plates. The two clamping plates are fixed with bolts to clamp and fix the clamping drive component 2502. The central area of ​​the mounting base 2501 has a groove reserved for fixing the clamping drive component 2502. The mounting base 2501 has multiple mounting holes, which are evenly distributed along the circumference of the mounting base, for detachable connection with the egg tray feeding device 2 by bolts. The clamping drive component 2502 is a clamping arm cylinder, which is cylindrical in shape. The piston end of the clamping drive component 2502 has a U-shaped groove (fitting the shape of the connecting end of the clamping arm 2503) in the center. The two side walls of the groove have symmetrical hinge holes (the hole diameter matches the pin, the hole axis is horizontal and penetrates the two side walls) to ensure that the clamping arm 2503 can be hinged by the pin after being inserted. The side of the clamping drive component 2502 has an air inlet 2507 connected to the pump station through a connecting air pipe. The air inlet 2507 extends out of the outer side of the mounting base 2501 and drives the piston to extend and retract by air pressure. The bottom of the cylinder of the clamping drive component 2502 has a strip hole 2506, which can limit the opening stroke of the clamping arm 2503. The strip hole 2506 is set along the length of the cylinder and its length is adapted to the maximum opening range of the clamping arm 2503. Two clamping arms 2503 are symmetrically distributed and are L-shaped. One end is a connecting end (the connecting end is a block that fits the slot of the clamping drive 2502. The thickness of the two connecting ends is less than the width of the slot to ensure easy insertion). A through hole is opened at the end of the connecting end (the diameter of the through hole is consistent with the hinge hole of the piston output end, so that it can be precisely aligned with the hinge hole after being inserted into the slot). The other end is a clamping end to ensure that it can fit against the side of the egg tray. The anti-slip mat 2504 is made of wear-resistant elastic silicone material, which has high friction and anti-aging properties. It can increase the contact friction with the egg tray and prevent wear and failure after long-term use. The anti-slip mat 2504 is elongated and its outline is smaller than the inner outline of the clamping end of the clamping arm 2503. The surface of the anti-slip mat 2504 may be provided with anti-slip texture (such as diamond pattern or stripe) to further improve the coefficient of friction. The anti-slip mat 2504 is attached to the inner side of the clamping end of the clamping arm 2503 by glue (high-strength epoxy resin glue) or by snap-fit, completely covering the area of ​​the clamping end in contact with the egg tray, ensuring a tight fit with the side of the egg tray when gripping. Multiple piercing spikes 2505 are evenly distributed along the width of the anti-slip pad 2504. The piercing spikes 2505 are made of stainless steel. One end of the piercing spike 2505 is a blunted tip, and the other end is a fixed end, which facilitates connection with the clamping arm 2503. The length is shorter than the thickness of the anti-slip pad 2504 to ensure that the tip is not exposed when not gripping, and can only pierce the surface of the arched part of the egg tray when gripping. When inflating, the piston extends, the two clamping arms 2503 are in an open state, and the distance between them is greater than the width of the arched part of the egg tray. The anti-slip pad 2504 and the piercing nail 2505 are in a non-working position. The clamping drive 2502 vents and the output end retracts, driving the clamping arm 2503 to rotate around the hinge point and close inward. First, the anti-slip pad 2504 contacts the side of the egg tray, and the egg tray is initially fixed by friction. As the clamping arm 2503 continues to close, the anti-slip pad 2504 is squeezed and deformed, and the piercing nail 2505 pierces the surface of the arched part of the egg tray. The dual action ensures that the egg tray is firmly clamped. When in use, after the egg tray is transferred to the destination area, the clamping drive 2502 is vented in reverse, the output end of the piston extends, and the clamping arm 2503 opens outward; the piercing nail 2505 is pulled out from the edge of the egg tray, the anti-slip pad 2504 is detached from the egg tray, and the egg tray is placed stably in the receiving area.

[0017] In this embodiment, Figure 1 The illustration shows an application scenario of an egg tray mechanical gripper for egg sorting. An egg tray feeding device 2 is set on one side of the egg sorting equipment. The egg tray feeding device 2 includes a frame, on which a lifting mechanism for carrying stacked egg trays and a transfer mechanism for transferring the top egg tray to the egg sorting equipment are provided. The transfer mechanism includes a traversing mechanism and a mechanical gripper assembly 25. The traversing mechanism is mounted on the frame, and the mechanical gripper assembly 25 is connected to the traversing mechanism. The traversing mechanism can drive the mechanical gripper assembly 25 to move back and forth between the lifting mechanism and the egg sorting equipment above the lifting mechanism.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
