[0027] Through the above technical scheme, the novel five-gun back filling mechanical hand adopts the "door" shaped linear frame body 1 structure, the filling mechanical hand is arranged between the frame body 1, and the automatic material injection operation of the refrigerator cabinet is carried out through the clamp 6, which adapts to the efficient and accurate production demand. The filling beam 12 in the filling mechanical hand is vertically attached to the inner side of the frame body 1, the driving force is provided by the inverted servo motor 2 on the outer side, the longitudinal synchronous shaft 11 is connected to the power output end, and the linear movement in the X-axis direction is realized by the rack 4 transmission.

[0028] In the use process, when the refrigerator cabinet is fixed by the clamp 6, the servo motor 2 drives the filling mechanical hand to move according to the set path, and the filling gun head 5 accurately injects material in the specified position in turn. The design can be flexibly adjusted in X, Y and Z directions, which adapts to refrigerator cabinets of different shapes and sizes, and ensures the uniformity and coverage rate of the injection.

Combined with the advantages of automation and precise control, this new type of filling manipulator brings a more efficient, more accurate and more economical solution to foaming filling operation. Embodiment two

[0032] Combined Figures 2-5 As shown in the above embodiment, the embodiment further gives the following content on the basis of the above embodiment:

[0033] In this embodiment, the guide rail 3 slider is symmetrically arranged on both sides of the rack 4 and can be driven with the rack 4 to reduce the jolt of transmission.

[0034] The filling stand 8 is designed as a hollow structure and is provided with uniform through holes from top to bottom to reduce the dead weight and eliminate stress concentration.

[0035] The filling cross beam 12 is designed as two sections and forms a "mouth" shaped frame with the inner side of the frame body 1, and the longitudinal gap can be adjusted according to the size of the refrigerator box body, and the filling gun head 5 of the five movable arms 9 is arranged thereon for accurate filling of the refrigerator box body.

[0036] The frame body 1 is symmetrically laid with a drag chain 7 on both sides, which can be folded with the filling manipulator to supply energy for the three-axis positioning servo motor 2.

[0037] The utility model discloses a filling mechanical hand adopts multiple optimization design, can realize efficient stable operation in filling foaming process. Its rack 4 both sides symmetrical layout has the guide rail 3 slider, the guide rail 3 slider can work in coordination with rack 4 transmission system, ensure that the mechanical hand keeps stable in the operation process. Through this arrangement, effectively reduce the bump phenomenon when transmission, especially in the high -speed transmission or positioning accuracy requirement is higher, can avoid the filling deviation caused by vibration, thereby improve the foaming uniformity and filling effect.

[0038] Filling stand 8 adopts hollow design, and the internal structure is uniformly distributed with multiple through holes from top to bottom. This design not only reduces the overall weight of the column, but also effectively disperses the stress concentration, avoids the structural damage caused by excessive load in long-term use. In practical application, this hollow design significantly improves the flexibility and durability of the filling mechanical hand, especially in the working condition that needs to move or adjust the filling position frequently.

[0039] Filling crossbeam 12 adopts two-section design, and the whole is in the shape of "mouth" character, and forms an adjustable frame body with the inner side of frame body 1. The longitudinal gap can be adjusted according to the size of different refrigerator boxes, so that the equipment has greater adaptability. Five movable arms 9 are arranged on the crossbeam, and each movable arm 9 is connected with a filling gun head 5. Through the independent movement of the movable arm 9, the five gun heads can accurately fill different areas of the refrigerator box. This multi-gun head design can cover multiple positions at the same time, effectively shorten the time of single filling, significantly improve the foaming efficiency, and meet the uniform filling demand of complex box structure.

[0040] Frame body 1 is paved with drag chain 7 that moves with the mechanical hand, and the drag chain 7 always keeps the compact arrangement of the cable in the folding and unfolding process, avoiding the damage of the power supply line caused by pulling or bending. The drag chain 7 is internally preset with the power supply line for the three-axis positioning servo motor 2, and through reasonable layout design, the servo motor 2 can obtain stable power supply in different positions, not only improves the operation reliability of the equipment, but also simplifies the operation and maintenance, so that the whole system is more safe and efficient.

[0041] Through these designs, the filling mechanical hand can realize stable three-axis positioning movement in the filling foaming process, and accurately complete the filling operation of the complex refrigerator box. The combination of rack 4 and guide rail 3 slider ensures the smoothness of the movement, hollow filling stand 8 reduces the weight and enhances the structural reliability, the adjusting function of two-section filling crossbeam 12 provides the possibility for the equipment to adapt to various box specifications, and the flexible power supply of drag chain 7 ensures the stability of the equipment in long-time operation. These function integrations make the utility model equipment become an efficient, stable and reliable solution in the field of filling and foaming.

[0042] Further, the movable arm 9 is provided with an independent rack 4 and a guide rail 3 slider, and is connected with a motor drive, which can cooperate with the filling gun head 5 to perform independent transverse adjustment, so that the filling gun head 5 maintains high accuracy.

[0043] Further, the five movable arms 9 can be independently adjusted according to different refrigerator box specifications, and can be fully filled or partially filled, can maintain 100% filling amount, or can independently adjust the filling amount of each filling gun head 5, thereby improving the universality of the filling robot.

[0044] The working principle and use process of the utility model are as follows:

[0045] Firstly, the refrigerator box is sent into the clamp 6 through the conveying line, the clamp 6 fixes the position of the refrigerator box after locking, and ensures that the box is stable during the subsequent filling process. Next, the servo motor 2 drives the synchronous shaft 11 to start working, and the filling robot is moved and positioned along the guide rail 3 through the rotation of the shaft. The guide rail 3 system drives the robot to be accurately controlled in multiple axial directions, and the coordinated work of the servo motor 2 and the synchronous shaft 11 ensures that the filling gun head 5 can be accurately positioned to the required position in space.

[0046] During the process, the filling gun head 5 is synchronously moved in X, Y and Z directions through the driving of the servo motor 2, so as to ensure the comprehensive coverage and uniformity of the filling process. Firstly, the motor drives the gear to move along the rack 4, so that the filling column 8 moves up and down in the Z axis direction, adjusts the height of the filling gun head 5, and accurately aligns the filling area of the refrigerator box. Then, the filling beam 12 moves transversely in the Y axis direction through the rack 4 transmission mode, so as to ensure that the filling gun head 5 can cover the width range of the refrigerator box. Finally, the movable arm 9 realizes the forward and backward movement in the X axis direction through the rack 4 system, allows the filling gun head 5 to be finely adjusted in the horizontal direction, and further improves the positioning accuracy.

[0047] During the whole filling process, multiple filling gun heads 5 work simultaneously, which can efficiently complete the filling task of a large area. The center distance of each filling gun head 5 is automatically adjusted by the servo motor 2, so that different sizes of refrigerator boxes can be accurately filled, and the situations of overfilling or underfilling do not occur. The movement in each direction is accurately controlled by the servo motor 2, and the stable transmission of the rack 4 is combined, so that the filling process is not jolted, thereby avoiding the waste and quality problems of the filling material.

[0048] In addition, the drag chain 7 structure on both sides of the frame body 1 can be automatically folded along with the movement of the filling manipulator, ensuring that the power supply line is not pulled or disturbed, thereby avoiding power interruption or line damage. The design of the entire filling system not only improves work efficiency, but also effectively reduces the probability of equipment failure, ensuring smooth filling operation. The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
