Description

Technical Field

[0001] This utility model relates to the field of injection molding production and processing equipment, specifically to an automatic unloading robot for injection molded parts that prevents material mixing. Background Technology

[0002] In the injection molding process, injection molded parts are mainly produced by injection molding machines and molds. For injection molded parts with waste structures such as gates and runners, automatic unloading after demolding is the key to ensuring the efficient operation of the production line.

[0003] Existing unloading robots sometimes over-grip plastic products with waste material attached after mold separation, causing them to fall and mix with other materials. Furthermore, after the finished product is separated, the waste material can also fall directly when the gripping cylinder is opened, resulting in mixing with other materials. When mixing occurs, manual sorting is required, and the presence of waste material in the finished product will also affect the product quality. Therefore, there is a need for an automatic unloading robot for injection molded parts that prevents mixing. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic unloading robot for injection molded parts that prevents material mixing. This avoids the problems of material breakage and mixing caused by excessive clamping, and the direct drop of waste material after the finished product is separated from the clamp. This prevents material mixing and improves the production efficiency and processing quality of injection molded parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic unloading robot for injection molded parts to prevent material mixing, comprising a robot and a base fixed to the output end of the robot. The base is provided with a plurality of first gripper cylinders, and a second gripper cylinder is provided on both sides of each first gripper cylinder. The grippers of the second gripper cylinders are detachably connected to mounting plates, and the grippers of the first gripper cylinders are detachably connected to anti-overhead plates. The upper end of the anti-overhead plates is provided with gripping forks, and the notches of the gripping forks of the anti-overhead plates are provided with material-supporting limiting posts.

[0006] Furthermore, the base is provided with a positioning groove, and the first gripper cylinder and the second gripper cylinder are both located in the positioning groove. The first gripper cylinder and the second gripper cylinder are detachably connected to the base.

[0007] Furthermore, a rubber block is detachably connected to the mounting plate.

[0008] Furthermore, the clamping fork has a U-shaped cross-section, and the clamping fork and the material support limiting post are integrated into one piece.

[0009] Furthermore, both the rubber block and the clamping fork are provided with anti-slip grooves.

[0010] Furthermore, the cross-section of the material support limiting post is L-shaped, and the material support limiting post is horizontally arranged on the clamping fork.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: it can avoid the problems of material breakage and mixing caused by excessive clamping and the direct drop of waste material after the finished product is separated from the clamp, thus avoiding material mixing and improving the production efficiency and processing quality of injection molded parts.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 An automatic unloading robot for injection molded parts with anti-mixing properties includes a robot and a base 1 fixed to the output end of the robot. The base 1 is provided with a plurality of first gripper cylinders 2. A second gripper cylinder 3 is provided on both sides of each first gripper cylinder 2 on the base 1. The grippers of the second gripper cylinder 3 are detachably connected to mounting plates 301. The grippers of the first gripper cylinders 2 are detachably connected to anti-overhead plates 4. The upper end of the anti-overhead plates 4 is provided with gripping forks 401. The notch of the gripping forks 401 of the anti-overhead plates 4 is provided with a material support limiting post 402.

[0019] A positioning groove 101 is provided on the base 1, which is used to position and install the first gripper cylinder 2 and the second gripper cylinder 3. A rubber block 302 is detachably connected to the mounting clamping plate 301, which can provide cushioning when clamping the product 6.

[0020] The clamping fork 401 has a U-shaped cross section. The clamping fork 401 and the material support limiting post 402 are integrated. The clamping fork 401 is used to clamp the waste material 5. After the first gripper cylinder 2 releases the clamp, the material support limiting post 402 can support the waste material head 5 to prevent it from falling.

[0021] Anti-slip grooves are provided on the rubber block 302 and the clamping fork 401 to improve the clamping effect on the product 6 and the waste head 5 and prevent the material from slipping. The cross-section of the material support limiting post 402 is L-shaped. When the jaws of the first gripper cylinder 2 perform the clamping action, the protruding parts and notches of the two material support limiting posts 402 match to avoid interference. At the same time, the presence of the material support limiting post 402 can limit the clamping action of the first gripper cylinder 2 to prevent the waste head 5 from breaking due to over-clamping. When separating the product 6 from the waste head 5, the broken material falls and mixes with the product 6. The material support limiting post 402 is set horizontally on the clamping fork 401. After the product 6 and the waste head 5 are separated, the waste head 5 can still remain stably on the material support limiting post 402 after the jaws of the first gripper cylinder 2 open.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
