Description

Technical Field

[0001] The utility model relates to the technical field of injection molding equipment, in particular to an integrated nut embedding manipulator mechanism. Background Art

[0002] In the industrial production process of injection molding products, it is usually necessary to embed nuts in the injection molding products. The commonly used nut embedding molding is to heat the nut and use its heat conduction principle to indirectly heat the plastic part, so that it will melt and bite with the nut, thereby achieving the purpose of implanting the nut. Although this implantation method is relatively cheap, when encountering plastics with poor melting properties, the nut and the plastic are not completely engaged or the bite force is insufficient, and the nut is prone to fall off.

[0003] At present, the way of embedding nuts in the injection molding industry has gradually evolved from manual embedding to mechanized embedding. The manual embedding method is not very accurate and inefficient, and there is a risk of missing nuts. The current mechanized embedding method is relatively simple. When multiple and various nuts need to be embedded in the injection molded parts at the same time, it will become very difficult and the time cost will be relatively high. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an integrated nut embedding robot mechanism with a simple structural layout, which realizes automated nut embedding action and improves work efficiency.

[0005] To achieve the above purpose, the utility model adopts the following contents:

[0006] The utility model provides an integrated nut embedding manipulator mechanism, which comprises a mounting portion connected to the output end of the multi-axis manipulator, the mounting portion is downwardly connected to a bearing plate body, the bearing plate body is provided with at least one set of clamping and embedding components, and one side of the bearing plate body is provided with a suction cup removal component outwardly;

[0007] The clamping and embedding component includes a plurality of clamping cylinders and pressing and positioning rods which are combined in a set. The clamping cylinders are vertically fixed on the supporting plate body, and the two output ends thereof are respectively provided with clamping arms which are located below the bottom end surface of the supporting plate body; the pressing and positioning rods are movably inserted from top to bottom on the surface of the supporting plate body, and the lower part of the pressing and positioning rods can pass from top to bottom between the two clamping arms, and the upper parts of the plurality of pressing and positioning rods are commonly connected to a horizontal displacement plate, and the surface of the supporting plate body is provided with a lifting cylinder for controlling the upward and downward movement of the displacement plate relative to the supporting plate body.

[0008] According to the integrated nut embedding manipulator mechanism provided by the utility model, a triangular clamping groove is provided on the inner side surface of the clamping arm. By designing the clamping groove of this shape, it can flexibly adapt to the clamping action of nuts of different diameters, improve the clamping effect, and avoid accidental falling of the nut during the removal process.

[0009] According to the integrated nut embedding manipulator mechanism provided by the utility model, the bottom end of the pressing and positioning rod is provided with a pressing contact portion with a slightly larger diameter, so as to increase the contact area between the pressing contact portion and the top of the nut, and ensure that the pressing and positioning rod can perfectly press the nut downward into the injection mold.

[0010] According to the integrated nut embedding manipulator mechanism provided by the utility model, the suction cup removal assembly includes a supporting side frame connected to the bearing plate body, and a horizontal displacement plate is arranged on the other side of the supporting side frame, and four suction cups arranged in a rectangular shape are vertically arranged on the displacement plate. The injection molded part after the nut is embedded is sucked and fixed by four suction cups, and the fixing effect is very stable and reliable, and it is not easy to loosen or slide, which can effectively ensure the safety and stability of the injection molded part.

[0011] Furthermore, the displacement plate is connected to the supporting side frame via a Y-axis driving module, and the Y-axis driving module enables the displacement plate to move up and down relative to the supporting side frame. In this way, the suction cup on the displacement plate can be driven by the Y-axis driving module to approach the injection molded part on the injection mold so as to absorb the injection molded part.

[0012] Compared with the prior art, the utility model has the following advantages: the utility model has a simple structure and a reasonable design. Through a plurality of groups of clamping and embedding components, the clamping and embedding of multiple and various nuts is realized, which has wide applicability and high work efficiency; the clamping action of the nut is realized by the clamping claw cylinder, and the nut clamped by the clamping claw cylinder is pressed down into the corresponding hole on the injection mold by pressing the positioning rod to complete the nut embedding action; the injection molded part with the nut embedded on the injection mold is moved by the suction cup removal component; the manipulator mechanism of the utility model does not require manual participation in the whole process, which can effectively improve production efficiency.

DETAILED DESCRIPTION

[0018] In order to explain the present invention more clearly, the present invention is further described below in conjunction with preferred embodiments. Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0020] See also Figure 1 , Figure 2 and Figure 3 As shown. The embodiment of the utility model proposes an integrated nut embedding robot mechanism, including a mounting portion 1 for connecting to the output end of a multi-axis robot, and the multi-axis robot realizes the free movement of each axis of the mounting portion. The mounting portion 1 is connected downwardly to a bearing plate body 10, and at least one group of clamping and embedding components 20 is arranged on the bearing plate body 10. In this embodiment, two groups of mirror-symmetrical clamping and embedding components are arranged on the left and right sides, and a suction cup removal component 30 is arranged outwardly on one side of the bearing plate body 10.

[0021] The clamping and embedding component 20 includes a plurality of clamping cylinders 210 and pressing and positioning rods 220 that are combined in a set. The number and layout of the clamping cylinders 210 can be reasonably adjusted according to the actual design of the product to be embedded. The clamping cylinder 210 is vertically fixed on the carrier plate body 10, and its two output ends are respectively provided with clamping arms 211 below the bottom end surface of the carrier plate body 10. The pressing and positioning rods 220 are movably inserted from top to bottom on the surface of the carrier plate body 10, and the lower part of the pressing and positioning rods 220 can pass from top to bottom between the two clamping arms 211. The upper parts of the plurality of pressing and positioning rods 220 are commonly connected to a horizontal displacement plate 320. The surface of the carrier plate body 10 is provided with a lifting cylinder 240 for controlling the up and down movement of the displacement plate 320 relative to the carrier plate body 10.

[0022] During actual use, the multi-axis manipulator moves the mechanism to the top of the nut loading station, controls the mechanism to move downward and approach the nut loading station, controls the clamping cylinder to accurately clamp each nut at the nut loading station, and then the multi-axis manipulator moves the entire mechanism to the top of the injection mold and controls it to move downward step by step, so that the nuts clamped on the clamping cylinder are inserted downward into the corresponding holes, and the two clamping arms are controlled by the clamping cylinder to separate, and then the lifting cylinder controls the displacement plate to drive the pressing and positioning rod to move downward as a whole, and the nut is further pressed into the injection mold by the lower part of the pressing and positioning rod to complete the nut embedding; then the multi-axis manipulator adjusts the angle of the load-bearing plate so that the suction cup removal assembly thereon moves to the top of the processed injection molded part, and sucks the injection molded part to complete the transfer of the injection molded part; then the above process is repeated.

[0023] In this embodiment, a triangular clamping groove 212 is recessed inwardly on the inner side of the clamping arm 211. By designing such a clamping groove, it is possible to flexibly adapt to the clamping action of nuts of different diameters, improve the clamping effect, and prevent the nuts from accidentally falling during removal.

[0024] In this embodiment, a slightly larger diameter pressing contact portion 221 is provided at the bottom end of the pressing and positioning rod 220. This increases the contact area between the pressing contact portion and the top of the nut, ensuring that the pressing and positioning rod can perfectly press the nut downward into the injection mold.

[0025] In this embodiment, the suction cup removal assembly 30 includes a supporting side frame 310 connected to the carrier plate body 10, and a horizontal displacement plate 320 is arranged on the other side of the supporting side frame 310. Four suction cups 321 arranged in a rectangular shape are vertically arranged on the displacement plate 320. The suction cups are standard vacuum suction cup pneumatic components. The injection molded parts are fixed by four suction cups after the nuts are embedded. The fixing effect is very stable and reliable, and it is not easy to loosen or slide, which can effectively ensure the safety and stability of the injection molded parts.

[0026] The displacement plate 320 and the supporting side frame 310 are connected via a Y-axis driving module 330, and the Y-axis driving module 330 realizes the up and down movement of the displacement plate 320 relative to the supporting side frame 310. In this way, the suction cup on the displacement plate can be driven by the Y-axis driving module to approach the injection molded part on the injection mold so as to absorb the injection molded part.

[0027] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
