Description

A car heat insulation pad gripping device and an industrial robot having the same. Technical Field

[0001] This invention relates to the field of industrial robots, specifically to an automotive heat insulation pad gripping device and an industrial robot having the same. Background Technology

[0002] With the deepening development of intelligent manufacturing in the automotive industry, more and more manufacturing scenarios require intelligent manufacturing methods and devices to meet the needs of these scenarios. Automotive heat insulation pads are accessories used to reduce heat accumulation inside the vehicle. They are mainly divided into hood heat insulation cotton and center console sunshade pads, which can effectively reduce engine compartment temperature, prevent paint aging, and improve driving comfort.

[0003] The production of automotive heat insulation pads is mainly carried out through high-temperature molding. If the molding edge is grasped before it is fully cooled, it is easy to cause deformation of the molding edge, which affects the tightness of the bonding between the various materials of the automotive heat insulation pad and the fit with the car mechanism after installation. Therefore, the heat insulation pad needs to be cooled first after molding, which leads to a decrease in production efficiency.

[0004] Therefore, a new type of automotive heat insulation pad gripping device and an industrial robot equipped with it are needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an automotive heat insulation pad gripping device and an industrial robot having the same.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A car heat insulation pad gripping device includes a template corresponding to the shape of the heat insulation pad. An air suction nozzle is fixed on the template along the corresponding position of the snap-fit ​​mounting hole on the heat insulation pad. The air suction nozzle includes a connecting frame, an adsorption plate, and a guide rod. The connecting frame is inserted and fixed on the template and limited and fixed by a screw assembly. There is a downward-facing guide rod in the center of the bottom surface of the connecting frame. The guide rod is hollow and has an air outlet at the bottom. An adsorption plate is fixed on the outside of the guide rod. Two air passages are provided inside the connecting frame, which are connected to the adsorption plate and directly connected to the guide rod through connecting pipes respectively. The other end of the air passages is connected to the air inlet and air outlet of the same air pump through an air guide pipe fixed on the template respectively.

[0008] As a further embodiment of the present invention: the adsorption plate is annular, consisting of a semi-circular bowl and an inner and outer edge extending from the inner and outer sides of the bowl. A guide rod passes through the central through hole of the bowl, and an annular stabilizing frame is fixed to the upper end of the guide rod. The adsorption plate is fixedly connected to the stabilizing frame.

[0009] As a further aspect of the present invention, the inner edge of the adsorption plate is set 2mm higher than the outer edge in horizontal height.

[0010] As a further aspect of the present invention: a guide head is inserted and fixed at the bottom of the guide rod, and a groove is recessed on the upper surface of the guide head to form a radially arranged air passage together with the guide rod structure.

[0011] As a further aspect of the present invention: a conical guide cone is convexly provided in the center of the upper surface of the guide head, and the cone surface of the guide cone is a concave arc-shaped cone surface.

[0012] As a further aspect of the present invention: a guide element that is hinged at the guide head groove and turned outward at an angle between 0 and 45° in the vertical upward direction is provided.

[0013] As a further aspect of the present invention: the flow guide includes a hollow shaft, side plates and a flow deflector. The hollow shaft is a hollow rotating shaft structure with side plates connected to both ends. The side plates are connected to each other through the flow deflector to form a U-shaped structure that rotates along the hollow shaft.

[0014] As a further aspect of the present invention: when the guide member is in the outward-folded state, the portion protruding from the guide rod and outside the guide head air passage is rounded.

[0015] As a further aspect of the present invention, a switching valve is installed in series on the air path of the air guide pipe to switch the connection with the air pump's inlet and outlet ends.

[0016] An industrial robot includes a multi-degree-of-freedom robotic arm, on which the aforementioned automotive heat insulation pad gripping device is mounted.

[0017] Beneficial effects

[0018] 1. The connecting frame of the present invention has a guide rod facing downward in the center of its bottom surface. The guide rod is hollow and has an air outlet at its bottom. An adsorption plate is fixed on the outside of the guide rod. Two air passages are provided inside the connecting frame, which are connected to the adsorption plate and the guide rod directly through connecting pipes. The other end of the air passages is connected to the air inlet and air outlet of the same air pump through air guide pipes fixed on the template. With the guide rod facing downward in the center of the adsorption plate, after the guide rod passes through the mounting hole of the heat insulation pad, the airflow blows out through the guide rod, which drives the airflow to blow on the mounting hole position, accelerates the cooling of the mounting hole position after hot pressing, and accelerates the shaping. At the same time, the airflow enters between the heat insulation pad and the support below, assisting in the separation of the support and the heat insulation pad, and facilitating the removal of the heat insulation pad.

[0019] 2. The present invention has a guide member hinged at the guide head groove, which is turned outward at an angle between 0-45° in the vertical upward direction, thereby guiding the airflow discharged from the guide rod at an angle. After passing through the mounting hole of the heat insulation pad, the guide member shrinks inward due to the influence of the mounting hole diameter, the guiding angle decreases, and the airflow is concentrated and guided to the mounting hole position, cooling the edge of the hot-pressed mounting hole and stabilizing the structure. Subsequently, it expands at the angle of the airflow and gravity, blowing towards the lower surface of the heat insulation pad at a larger angle for a wider range of cooling, and also assisting in the separation of the heat insulation pad from the support below.

[0020] 3. This invention uses a gripping device connected to a multi-degree-of-freedom robotic arm to directly feed the gripping device into the mold of the molding machine to grip the heat insulation pad, thereby improving efficiency. At the same time, the guide rod and guide head of the air suction nozzle are inserted into the molding hole and the air is sprayed out to remove the cut waste material and prevent waste blockage. At the same time, the constraint and guidance of the airflow angle of the guide component and the airflow through the molding hole can also improve the force of the airflow on the installation hole of the heat insulation pad and the cooling effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] This embodiment provides an automotive heat insulation pad gripping device, as shown in Figures 2, 3, and 4. It includes a template 2 corresponding to the shape of the heat insulation pad. An air suction nozzle 4 is fixed on the template 2 along the position of the snap-fit ​​mounting hole on the heat insulation pad. The air suction nozzle 4 includes a connecting frame 41, an adsorption plate 44, and a guide rod 42. The connecting frame 41 is inserted and fixed on the template 2 and is limited and fixed by a screw assembly. The bottom center of the connecting frame 41 has a downward-facing guide rod 42. The hollow bottom of the guide rod 42 has an air outlet. The adsorption plate 44 is fixed on the outside of the guide rod 42. Two air paths are provided inside the connecting frame 41, which are connected to the adsorption plate 44 and the guide rod 42 directly through connecting pipes 45, respectively. The other end of the air path is connected to the air inlet and air outlet of the same air pump through the air guide pipe 3 fixed on the template 2, respectively.

[0033] With the guide rod 42 with the adsorption plate 44 facing downwards, after the guide rod 42 passes through the mounting hole of the heat insulation pad, the airflow blows out through the guide rod 42, which drives the airflow to blow on the mounting hole position, accelerates the cooling of the mounting hole position after hot pressing, and accelerates the shaping. At the same time, the airflow enters between the heat insulation pad and the support below, assists in the separation of the support and the heat insulation pad, and facilitates the removal of the heat insulation pad.

[0034] As shown in Figure 5, the adsorption plate 44 is annular, consisting of a semi-circular bowl 441 and an inner edge 443 and an outer edge 442 extending from the inner and outer sides of the bowl 441. The guide rod 42 passes through the central through hole of the bowl 441, and an annular stabilizing frame 43 is fixed to the upper end of the guide rod 42. The adsorption plate 44 is fixedly connected to the stabilizing frame 43. The stabilizing frame 43 ensures the stability of the overall structure of the adsorption plate 44, avoids the uneven air pressure inside the bowl 441 caused by the deformation of the structure of the adsorption plate 44 under negative pressure, and thus ensures the uniformity of the suction force at all parts of the adsorption plate 44.

[0035] Furthermore, the inner edge 443 of the adsorption plate 44 is set 2mm higher than the outer edge in horizontal height, so that after the adsorption plate 44 adsorbs the heat insulation pad, a height difference will be formed between the inner and outer sides, which will lift the position of the buckle mounting hole on the heat insulation pad, so as to facilitate the entry of air and avoid the heat insulation pad being bent and damaged due to excessive adsorption force between the heat insulation pad and the mold of the molding equipment.

[0036] As shown in Figures 6, 7, and 8, a guide head 47 is inserted and fixed to the bottom of the guide rod 42. The upper surface of the guide head 47 is recessed with a groove, which together with the structure of the guide rod 42 forms a radially arranged air passage to guide the airflow and improve the cooling effect. A conical guide cone 48 is protruding in the center of the air passage. The cone surface of the guide cone 48 is a concave arc-shaped cone surface to guide the airflow and reduce flow velocity loss.

[0037] Specifically, a guide element 46 is hinged at the groove of the guide head 47, which is turned outward at an angle between 0 and 45° in the vertical upward direction. This guide element 46 guides the airflow discharged from the guide rod 42. After passing through the mounting hole of the heat insulation pad, the guide element 46 shrinks inward due to the diameter of the mounting hole, the guiding angle decreases, and the airflow is concentrated and guided to the mounting hole position. This cools the edge of the hot-pressed mounting hole and stabilizes the structure. Subsequently, the airflow expands at the angle of the interaction between the airflow and gravity, blowing towards the lower surface of the heat insulation pad at a larger angle for greater cooling and also assisting in the separation of the heat insulation pad from the support below.

[0038] Furthermore, the flow guide 46 includes a hollow shaft 461, side plates 462 and flow deflector 463. The hollow shaft 461 is a hollow rotating shaft structure with side plates 462 connected to both ends. The side plates 462 are connected to each other through the flow deflector 463, forming a U-shaped structure that rotates along the hollow shaft 461, thereby better constraining and guiding the airflow.

[0039] Furthermore, when the guide component 46 is in the outward-folded state, the part protruding outside the air passage of the guide rod 42 and the guide head 47 is rounded, thereby reducing the wear of the heat insulation pad by the outward-folded guide component 46 and the possibility of it getting stuck when passing through.

[0040] Among them, the air guide pipe 3 is equipped with a switching valve that can switch the connection with the air pump's inlet and outlet ends, so that the air path can be reversed and the air is discharged in reverse through the adsorption plate 44 to assist the separation of the heat insulation pad and the air suction nozzle 4.

[0041] An industrial robot, as shown in Figure 1, includes a multi-degree-of-freedom robotic arm 1. The multi-degree-of-freedom robotic arm 1 is equipped with the aforementioned automotive heat insulation pad gripping device, which can directly feed the gripping device into the mold of the molding machine to grip the heat insulation pad, thereby improving efficiency. At the same time, through the guide rod 42 and guide head 47 of the air suction nozzle 4, the cutting waste material at the installation hole is discharged to prevent the waste material from clogging. At the same time, the constraint and guidance of the airflow on the angle of the guide component 46 and the airflow by the molding hole can also improve the force of the airflow on the installation hole of the heat insulation pad and the cooling effect.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
