Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production equipment, in particular to a hot pressing forming workpiece transfer device. Background Art

[0002] In the traditional production of automotive parts, hot pressing one-piece molding is often used to manufacture larger workpieces. Hot pressing molding has the advantages of high precision, high strength, and high production efficiency.

[0003] Traditional hot pressing devices cannot realize automatic loading and unloading, and need to be manually removed. However, the high surface temperature of the workpiece formed by hot pressing can easily cause injuries to workers. In order to improve production efficiency and product quality, it is necessary to improve the existing production process and equipment.

[0004] CN202021784470.9 discloses a hot pressing forming device for automobile roof with trimming function and automatic unloading, specifically comprising a base, a lower mold, an upper mold, a transfer mechanism and a mounting arm. A frame is installed on the top of the base, and a control panel is fixed at the middle position of one side of the frame. A hydraulic cylinder is installed on the side of the top of the frame away from the control panel, and a pressure plate is installed on the output end of the hydraulic cylinder. Stamping guide columns penetrate the four corners of the pressure plate, and the bottom ends of the stamping guide columns are connected to the base. The hot pressing forming device for automobile roof with trimming function and automatic unloading is provided with a transfer mechanism and a conveyor belt. The transfer mechanism can absorb the material to be hot pressed by a vacuum suction cup and transfer it to the forming groove to realize automatic loading. After the hot pressing is completed, the formed automobile roof can be automatically transferred back to the conveyor belt for transmission. The whole process does not require manual handling, which is more convenient to use and more convenient for mass production of automobile roofs.

[0005] The transfer mechanism of the above-mentioned device mainly completes the automatic loading and unloading operations through the vacuum suction cup. However, in actual work, since the temperature of the workpiece after hot pressing is high and the vacuum suction cup cannot withstand high temperature, the workpiece needs to be cooled to a certain temperature before unloading operation can be carried out. If the cooling operation is not performed, the vacuum suction cup will cause it to melt.

[0006] Based on this, the technical problem solved in this case is: how to further optimize the device for automatically transferring workpieces after hot pressing. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a hot pressing formed workpiece transfer device. The device can automatically transfer the workpiece after hot pressing, reducing the labor intensity of the staff. Compared with the traditional transfer mechanism, the grasping is more stable and reliable, and it can transfer workpieces with higher temperatures, reducing the waiting time, thereby improving work efficiency.

[0008] The technical solution of the utility model is:

[0009] A hot pressing workpiece transfer device comprises a hot pressing mechanism and a transfer mechanism, wherein the hot pressing mechanism is provided with a forming cavity for the hot pressing workpiece; the transfer mechanism is arranged next to the hot pressing mechanism, and the transfer mechanism comprises a mechanical arm, a mounting assembly mounted on the mechanical arm, and a plurality of grasping assemblies arranged on the mounting assembly; the grasping assembly is provided with a pricking needle for grasping the periphery of the formed workpiece.

[0010] One of the above technical solutions of the utility model has at least one of the following advantages or beneficial effects:

[0011] After the utility model completes the forming of the workpiece through the hot pressing mechanism, the transfer mechanism starts working immediately, and the installation component and the grasping component are driven by the mechanical arm to move to the forming cavity. This movement process is not only stable and reliable, but also fast and accurate, which can effectively improve the efficiency. In addition, the grasping component grasps the workpiece by piercing the periphery of the formed workpiece with a needle. Compared with the traditional grasping method, not only the grasping is stable, but also the service life of the grasping component can be increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figures 1 to 4A hot pressing workpiece transfer device comprises a hot pressing mechanism 1 and a transfer mechanism 2. The hot pressing mechanism 1 is provided with a forming cavity for the hot pressing workpiece; the transfer mechanism 2 is arranged beside the hot pressing mechanism 1, and the transfer mechanism 2 comprises a mechanical arm 21, a mounting assembly 22 mounted on the mechanical arm 21, and 8 grasping assemblies 23 arranged on the mounting assembly 22; the 8 grasping assemblies 23 are arranged along the periphery of the formed workpiece; the grasping assembly 23 is provided with a pricking needle 231 for grasping the periphery of the formed workpiece.

[0019] In this embodiment, after the hot pressing mechanism 1 completes the forming of the workpiece, the transfer mechanism 2 starts working and drives the installation component 22 and the grasping component 23 to move to the forming cavity through the mechanical arm 21. This movement process is not only stable and reliable, but also fast and accurate, which can effectively improve the efficiency. In addition, the grasping component 23 grasps the workpiece by piercing the periphery of the formed workpiece with a needle 231. Compared with the traditional grasping method, not only is the grasping stable, but also the service life of the grasping component 23 can be increased.

[0020] In this embodiment, it should be noted that, generally speaking, the periphery of the hot-pressed workpiece is waste material, which needs to be cut off in the subsequent process before normal use, so the puncture position of the needle 231 should be located at these positions.

[0021] In this embodiment, the mounting assembly 22 includes a connecting block 221 mounted on the robot arm 21 and a positioning frame 222 fixed on the connecting block 221; the positioning frame 222 is arranged along the outer circumference of the molding cavity.

[0022] Since the workpiece shown in this embodiment is a fender, the positioning frame 222 is specifically a square frame.

[0023] In this embodiment, specifically, the grabbing assembly 23 includes a first extension rod 232 and a power module 233; the first extension rod 232 is fixed on the positioning frame 222 and extends toward the periphery of the molded workpiece; the power module 233 is fixed on the first extension rod 232 and is used to drive the needle 231 to move toward the periphery of the molded workpiece.

[0024] In the above design, the first extension rod 232 is disposed on the edge of the positioning frame 222 and extends toward the molding cavity.

[0025] In this embodiment, more specifically, the power module 233 includes a guide block 2331 arranged on the first extension rod 232, and two cylinders 2332 arranged on the guide block 2331; a limit block 2333 is provided on the power output end of the two cylinders 2332; the needle 231 is fixed on the limit block 2333 and passes through the guide block 2331 to grasp the periphery of the formed workpiece.

[0026] In this embodiment, the cylinder 2332 is used as the power because of its small size, sufficient pressure, and easy control. It is more suitable than oil cylinders, motors, etc. In order to ensure the accuracy of the puncture position of the needle 231, this embodiment also uses a limit block 2333 and a guide block 2331 to ensure that the puncture position of the needle 231 does not exceed the waste material on the periphery of the workpiece to avoid economic losses.

[0027] In order to make the grasping more secure, the two cylinders 2332 are symmetrically arranged inwardly tilted, so that the puncture needles 231 on the two cylinders 2332 form a closed grasping portion, thereby ensuring the firmness of the grasping.

[0028] In this embodiment, in order to prevent the molded workpiece from bending due to force when demolding, the transfer mechanism 2 also includes a clamping assembly 24; the clamping assembly 24 includes a second extension rod 241 and a pressure block 242; the second extension rod 241 is fixed on the positioning frame 222 and extends toward the molded workpiece; the pressure block 242 is arranged on the second extension rod 241 and is used to clamp the molded workpiece.

[0029] Under the above design, the pressing block 242 can provide a certain supporting force for the concave part of the fender, thereby protecting its molded structure.

[0030] In this embodiment, in order to prevent the pressing block 242 from being melted, the pressing block 242 is made of a heat-resistant material.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
