Description

Technical Field

[0001] The utility model relates to the technical field of tile pressing machinery, and particularly relates to a mechanical arm of a full-automatic tile press. Background Art

[0002] The processing of cylinder tiles for building houses mainly includes processes such as crushing soil materials, making mud, pressing tile blanks, drying, firing, etc. The process of pressing tile blanks is an important process related to the quality and output of tile making. Traditional tile pressing production lines include a mud conveyor belt and a tile press. The tile press is mainly composed of a hydraulic press. A tile making lower die is installed at the bottom of the body of the hydraulic press, and a tile making upper die is installed on the oil top of the hydraulic press. Workers operate to press the brick blanks. Pressing the brick blanks requires operations such as taking mud materials, dipping mud materials in oil, placing materials, operating, taking tile blanks, placing tile blanks, etc. Each tile press needs at least five people to operate simultaneously to complete all operation items, which is a typical labor-intensive industry.

[0003] After retrieval, the Chinese patent with the publication number CN104476657B discloses a mechanical arm of a full-automatic tile press, including: an oil dipping mechanism, a material taking mechanism, and a tile taking mechanism, which greatly reduces the number of staff. Only one staff member for placing tile blanks is retained for one tile press, realizing full-automatic operation. The whole process time for pressing each tile blank < 4s, greatly reducing the labor intensity of workers and improving work efficiency.

[0004] However, before grasping the tile blank mud material from the conveyor belt, it is necessary to cooperate with a telescopic cylinder and a telescopic clamping plate to push and squeeze the tile blank mud material to make its placement angle constant. Since the tile blank mud material is relatively soft before sintering, it is easy to deform during the pushing process of the clamping plate, resulting in difficulty in entering the mold when the tile blank mud material is placed on the base of the tile press subsequently. Therefore, the present application provides a mechanical arm of a full-automatic tile press to meet the requirements. Summary of the Utility Model

According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments, and the adjustments or modifications made are still included in the scope of the appended claims. Detailed implementation manners

[0024] The following describes in detail a full-automatic tile press robotic arm provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it is noted here that in order to make the embodiments more detailed, the following embodiments adopt the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative ways to implement them; moreover, the drawing part is only for more specifically describing the embodiments and is not intended to specifically limit the present utility model.

[0025] As Figure 1 - Figure 3As shown in the figure, an embodiment of the utility model provides a robotic arm for a full-automatic tile press, comprising: a cantilever 1, fixedly connected with a telescopic cylinder 2 at the top, and the output end of the telescopic cylinder 2 faces downward; a lifting rod 3, slidably connected with the cantilever 1 in a matching manner. A sliding hole for slidably connecting the lifting rod 3 is formed on the cantilever 1, and both the sliding hole and the lifting rod 3 are of rectangular structures. The top of the lifting rod 3 is connected with the output end of the telescopic cylinder 2, and an extension rod 12 is arranged at the bottom end of the lifting rod 3. The extension rod 12 is of a round rod structure, and the diameter of the extension rod 12 is smaller than the width of the lifting rod 3; a material taking plate 4, with a rotating seat 10 arranged at the center of the top. The extension rod 12 is rotationally connected with the rotating seat 10 at the top of the material taking plate 4 in a matching manner. Two material taking angle sensors 6 are symmetrically arranged at both ends of the material taking plate 4, and the probes of the material taking angle sensors 6 face downward.

[0026] Among them, the material taking angle sensor 6 can adopt an image sensor (such as a CCD or CMOC sensor), capture the image of the tile blank mud material, and use image processing technology to analyze the placement angle of the tile blank mud material; or adopt a photoelectric sensor, and compare the positions of the edges of the rectangular tile blank mud material detected by multiple photoelectric sensors with the position of the normal marking line to judge the placement angle of the tile blank mud material.

[0027] By setting the material taking angle sensor 6 to detect the placement angle of the tile blank mud material, and then cooperating with the rotation of the material taking plate 4 in the same direction as the angle of the tile blank mud material, and resetting the angle of the material taking plate 4 after grasping, it is ensured that when the tile blank mud material is placed in the tile press, the tile blank mud material is aligned with the tile press mold, avoiding the deformation of the mud material caused by adjusting the clamping plate to push and squeeze the tile blank mud material for placement angle calibration.

[0028] As Figure 1 shown, a plurality of material taking suction cups 5 arranged in a rectangular array are provided at the bottom end of the material taking plate 4 for adsorbing the tile blank mud material.

[0029] Among them, the material taking suction cup 5 is connected with a vacuum generator. When the bottom of the material taking suction cup 5 is attached and sealed with the tile blank mud material, the vacuum generator works to make the inside of the material taking suction cup 5 form a vacuum, and the tile blank mud material is grasped under the action of negative pressure.

[0030] As Figure 3 shown, the bottom end of the extension rod 12 is fixedly connected with a chassis 14 through a connecting rod 13. Both the connecting rod 13 and the chassis 14 are of cylindrical structures and are coaxially arranged with the extension rod 12. The diameter of the connecting rod 13 is smaller than the diameter of the extension rod 12, and the diameter of the chassis 14 is larger than the diameter of the extension rod 12; a turntable 15 is also included, and the turntable 15 is sleeved outside the connecting rod 13, and a ball 18 is rollingly connected between the turntable 15 and the chassis 14.

[0031] By setting the diameter of the connecting rod 13 to be smaller than that of the extension rod 12, during the rotation of the turntable 15, the top of the turntable slides in cooperation with the bottom of the extension rod 12, thereby limiting the top of the turntable 15 and ensuring that the turntable 15 is always parallel to the bottom chassis 14, maintaining the stability of the rotating structure.

[0032] As Figure 2 shown, a number of balls 18 are provided and are distributed in an annular array. A first annular groove 16 is formed in the top of the chassis 14, and a second annular groove 17 is formed in the bottom of the turntable 15. Both the first annular groove 16 and the second annular groove 17 are in rolling connection with a number of balls 18 in cooperation.

[0033] By providing the balls 18, a relative rotational connection between the turntable 15 and the chassis 14 is achieved. While providing support for the material taking plate 4, the rolling connection replaces mechanical friction, not only reducing the rotational resistance but also reducing mechanical wear and extending the service life of the components.

[0034] As Figure 2 and Figure 3 shown, an installation groove 20 is formed in the bottom of the rotating seat 10. The top wall of the installation groove 20 is fixedly connected to the top of the turntable 15. A rotation hole 19 is formed at the center of the top wall of the installation groove 20 for rotatably connecting with the extension rod 12 in cooperation.

[0035] Among them, during the rotation of the rotating seat 10 and the extension rod 12, the top of the rotating seat 10 slides in cooperation with the top of the lifting rod 3, ensuring the overall levelness of the material taking plate 4.

[0036] As Figure 2 shown, it further includes a motor 7 fixedly connected to the side wall of the lifting rod 3. The output end of the motor 7 is connected to a gear 8; an annular tooth 11 is formed on the outer side wall of the top of the rotating seat 10, and the annular tooth 11 is in meshing connection with the gear 8 in cooperation.

[0037] Among them, the motor 7 is controlled by an automatic control system. The automatic control system uses a programmable controller (such as a PLC) to collect sensor data and send control instructions. The automatic control system controls the forward and reverse rotation and the rotation stroke of the motor 7 according to the data detected by the material taking angle sensor 6. The motor 7 uses a high-precision servo motor. The specific structure, working principle of this control system and its specific connection with the components of this embodiment will not be elaborated too much for those skilled in the art.

[0038] As Figure 2 shown, it further includes a limit plate 9 fixedly connected to the rod body of the lifting rod 3 and protruding from the side wall of the rod body of the lifting rod 3. The limit plate 9 is located above the motor 7.

[0039] With this setting, the risk of the top of the motor 7 colliding with the bottom of the cantilever 1 caused by excessive upward movement of the reset stroke of the telescopic cylinder 2 is avoided.

[0040] In the actual use of the technical solution provided by the present utility model, the tile blank mud is transported to the lower part of the material taking plate 4 through the conveyor belt. The placing angle of the tile blank mud is detected by the material taking angle sensor 6, and the information is sent to the automatic control system in the form of digital signals. The automatic control system sends an instruction to the motor 7, and the motor 7 drives the gear 8 to rotate. Cooperating with the meshing connection with the annular tooth 11, the rotation of the material taking plate 4 is realized, so that the plate body direction of the material taking plate 4 is the same as that of the tile blank mud below. Subsequently, the telescopic cylinder 2 is started, and the material taking plate 4 is driven to move downward integrally through the lifting rod 3, so that the bottom of the material taking suction cup 5 is attached to the top of the tile blank mud, and the tile blank mud is grabbed by suction through the vacuum generator. Subsequently, the telescopic cylinder 2 resets, driving the material taking plate 4 to rise. Subsequently, the material taking plate 4 with the grabbed tile blank mud is driven to the position of the tile press by the movement of the cantilever 1. During the movement of the cantilever 1, the motor 7 performs the reset work under the control of the reset program, driving the material taking plate 4 to complete the reset rotation. When the material taking plate 4 is transferred to the position of the tile press driven by the cantilever 1, the material taking plate 4 is in the initial angle position. Finally, after the tile blank mud is placed in the tile press die, the cantilever 1 drives the material taking plate 4 to return to the initial position integrally.

[0041] The present utility model covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. In addition, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, elements and circuits are not described in detail.

[0042] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
