Specific embodiments

[0019] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below in conjunction with the drawings.

[0020] Secondly, the present utility model is described in detail in combination with the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general ratio, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0021] To make the purpose, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below in conjunction with the drawings.

[0022] Such as Figures 1 to 6As shown in the figure, a material grabbing rack for an array - type sound insulation pad under a carpet provided by the utility model belongs to a part of the loading and transfer system. The loading and transfer system further includes a loading landing gear, a lifting material taking machine 3, and a transfer robot 4.

[0023] The loading landing gear includes a loading placement table 1 and a landing gear 2; the semi - finished products of the sound insulation pad under the carpet (hereinafter referred to as materials) from the previous process enter the loading placement table 1 and the landing gear 2 in sequence through a belt conveyor; the landing gear 2 includes a fixed part and a lifting part; the fixed part transfers the semi - finished product materials to the lower part of the lifting material taking machine 3; the lifting part can vertically lift the semi - finished product materials upward to facilitate the material taking machine to take materials.

[0024] This embodiment focuses on introducing the lifting material taking machine and the material grabbing rack through the following content:

[0025] The lifting material taking machine 3 includes a support frame 31 arranged on one side of the landing gear 2. The top of the support frame 31 is provided with a support frame 32 with upper and lower openings. One side of the support frame 32 is fixed with a bidirectional motor 36 and a matching speed reducer. A gear - rack transmission structure 33 is arranged inside the support frame 32. The output end of the speed reducer penetrates the inner wall of the support frame 32 and is coaxially fixed with the gear. The rack engaged with the gear is fixed on one side of a vertical strip - shaped lifting frame 34. A vertical slideway 37 is arranged on the lifting frame. A clamping block 38 is fixed on the side of the support frame 32 opposite to the slideway. An concave slide rail slidably matched with the slideway is arranged on the clamping block. Through the above structure, the bidirectional motor can drive the lifting frame to move up and down through the gear - rack transmission structure 33. On the side of the lifting frame away from the bidirectional motor, a moving lower limit sensor, a home position sensor, and a moving upper limit sensor are arranged from top to bottom in sequence. On the inner wall of the support frame 32 opposite to the above sensors, a limit block matched with the sensor is arranged. When the lifting frame moves downward to a certain extent, once the moving lower limit sensor senses the limit block, it sends a signal to the PLC. Similarly, when the moving upper limit sensor senses the limit block, it can send a signal to control the bidirectional motor to stop running when the lifting frame moves upward in place. The home position sensor defines the starting point of the initial operation of the lifting frame to control the rising and falling distances.

[0026] A first material grabbing rack 35 is fixed at the bottom of the lifting frame; the first material grabbing rack 35 includes a square frame 350 and a plurality of grippers 351 arranged in an array on one side of the square frame 350; the shape and size of the square frame 350 correspond to the semi - finished products of the sound insulation pad under the carpet; each gripper 351 includes a finger cylinder and two jaw bodies threadedly connected to the finger cylinder; each finger cylinder is connected with a compressed air pipeline, so as to control the opening of the jaw body through air pressure; all the compressed air pipelines are connected in parallel and are respectively provided with air sources and regulated airflows through the same compressed air source and flow valve.

[0027] The clamp body includes a connection part for connecting the finger cylinder, the connection part is provided with a threaded hole, and also includes a serrated part provided at the end of the connection part for easy insertion into the material; in order to enable the clamp body to grasp the material more stably, there is a certain angle between the connection part and the serrated part, so that the bottom ends of the two serrated parts are close to each other; before grasping the material, the opening of the two clamp bodies is the largest, so that they are inserted in an eight-shaped shape and obtain a larger grasping area. In the material lifting state, the two clamp bodies are close to each other, and the clamp body lifts the material in a tightened posture to prevent the material from falling.

[0028] Preferably, the finger cylinder is an AirTac Y-type finger cylinder, model HFY32, and the pressure range is 0.2-0.7MPa.

[0029] Through the above structure, when the semi-finished product of the sound insulation pad under the carpet is lifted by the landing gear 2, the first grabbing frame 35 moves downward until the clamping claws are inserted into the semi-finished product of the sound insulation pad under the carpet, and all the clamping claws clamp the semi-finished product and rise to a certain height.

[0030] The transfer robot 4 includes a robotic arm and a second grabbing frame; the second grabbing frame has the same structure as the first grabbing frame, and the square frame of the second grabbing frame is rotatably connected to the end of the robotic arm through a flange, so that the second grabbing frame can be flipped at any angle as needed.

[0031] The working principle of the utility model is as follows:

[0032] S1, landing gear 2 lifts the semi-finished product to a certain height;

[0033] S2, the lifting frame of the lifting reclaimer 3 moves downward, so that the first grabbing frame 35 approaches the material, the gripper 351 grabs the material and clamps it, and the landing gear 2 falls to its original position;

[0034] S3, after the first grabbing rack 35 carries the material and rises to a specified height, the grabber of the transfer robot clamps the material, and the grabber 351 of the first grabbing rack 35 is released and moves upward;

[0035] S4, the transfer robot 4 carries the material and puts it into the pressing station of the hydraulic press 5.

[0036] Although the present utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
