Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to a high-efficiency injection molded part clamping robot. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. An injection molding machine (or injection molding machine for short) is the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting materials. Injection molding is achieved through an injection molding machine and a mold.

[0003] Among them, in such Figure 7 During the injection molding process of the product shown, multiple sets of product parts are injected into the injection mold at the same time. There will be residual sprue waste between the multiple sets of product parts. After the injection is completed, the product parts and sprue waste need to be unloaded. The existing ejection unloading method puts the sprue and the workpiece in the same box. The operator needs to manually screen out the sprue afterward. The robot takes out the product part and then moves it to the cutting equipment to cut and remove the sprue. The process is relatively complicated and the production efficiency is low.

[0004] Therefore, it is necessary to invent a high-efficiency injection molded part gripper to solve the above problems. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 7 The illustrated high-efficiency injection molded part gripper includes a mounting base 1, which is I-shaped. First mounting plates 2 are fixedly connected to both the front and rear sides of the mounting base 1. Multiple sets of first pneumatic grippers 26 are mounted on the surfaces of both sets of first mounting plates 2. A second mounting plate 3 is mounted on the middle right side of the mounting base 1. Two sets of second pneumatic grippers 35 are mounted on the surface of the second mounting plate 3. Two sets of elastic elements 11 are mounted on the mounting base 1 and the second mounting plate 3. Vision sensors 12 are mounted on both the upper and lower sides of the middle right side of the mounting base 1.

[0027] The mounting base 1 is installed at the end of the four-axis robotic arm, which drives the mounting base 1 to move forward and backward, left and right, up and down, and rotate along the Y-axis.

[0028] During use, the four-axis robotic arm adjusts the mounting base 1 to a vertical position, then extends it into the inside of the injection mold 4. Next, the mounting base 1 is moved toward the product part 41 until the first pneumatic gripper 26 and the second pneumatic gripper 35 are respectively placed on the surface of the product part 41 and the sprue waste 42. At the same time, the right end of the second pneumatic gripper 35 will abut against the surface of the injection mold 4, and the second pneumatic gripper 35 will be activated to clamp and fix the sprue waste 42. Then, the mounting base 1 is moved to the right, which will compress the elastic element 11. When the elastic element 11 is compressed to the extreme, the first pneumatic gripper 26 is activated to clamp and fix the product part 41. Next, the robotic arm moves the mounting base 1 to the left. Under the action of the elastic element 11, the second pneumatic gripper 35 will press the sprue waste 42 against the surface of the injection mold 4. The first pneumatic gripper 26 will move the product part 41 to the left first. At this time, the instantaneous tension of the elastic element 11 will separate the product part 41 from the sprue waste 42. Then, the robotic arm will move the mounting base 1 to the waste bin to discharge the sprue waste 42. Finally, the product part 41 will be placed inside the storage box for storage. The system enables automatic separation of product parts 41 and sprue waste 42 during the material handling process, eliminating the need for secondary cutting and separation. This effectively improves the efficiency of product material handling and separation, enhances the ease of use of the equipment, and reduces production steps and equipment costs.

[0029] See Figure 2 and Figure 3The surface of the first mounting plate 2 has two sets of mounting grooves 21. The left side of the first pneumatic gripper 26 is fixedly connected to the first fixed seat 22. The left side of the first fixed seat 22 is fixedly connected to two sets of positioning blocks 25. The positioning blocks 25 are slidably connected to the mounting grooves 21. The upper and lower sides of the surface of the first fixed seat 22 are fixedly connected to two sets of fixing screws 23. The left end of the fixing screw 23 passes through the mounting groove 21 and is threadedly connected to a locking nut 24.

[0030] Meanwhile, during the installation of the first pneumatic gripper 26, the first pneumatic gripper 26 is first fixedly installed on the surface of the first fixed seat 22. At this time, the first fixed seat 22 is placed on the surface of the first mounting plate 2, and the positioning block 25 is locked inside the mounting groove 21. At the same time, the left end of the fixing screw 23 will pass through the mounting groove 21. Then, the locking nut 24 is threadedly connected to the left end of the fixing screw 23, and the first fixed seat 22 and the first pneumatic gripper 26 are fixedly installed on the surface of the first mounting plate 2.

[0031] In addition, by loosening the locking nut 24, the first fixed seat 22 and the first pneumatic gripper 26 slide up and down on the surface of the first mounting plate 2 via the positioning block 25, thereby adjusting the position of the first pneumatic gripper 26 and making it easy to increase or decrease its quantity, effectively improving the adaptability of the equipment.

[0032] See Figure 4 and Figure 5 Multiple sets of threaded holes 31 are provided on both the front and rear sides of the surface of the second mounting plate 3. A second fixed seat 32 is fixedly connected to the left side of the second pneumatic gripper 35. Two sets of mounting holes 33 are provided on both the front and rear sides of the surface of the second fixed seat 32. Locking screws 34 are inserted into the inside of the mounting holes 33 and are threadedly connected to the threaded holes 31.

[0033] It should be added that during the installation of the second pneumatic gripper 35, the second pneumatic gripper 35 is first installed and fixed to the second fixed seat 32. Then, the second fixed seat 32 is placed on the surface of the second mounting plate 3. Next, the locking screw 34 is passed through the mounting hole 33 and the threaded hole 31 to lock and fix it, thereby locking and fixing the second fixed seat 32, and then installing and fixing the second pneumatic gripper 35.

[0034] See Figure 4 and Figure 6The elastic element 11 includes a first connecting plate 111, a positioning cylinder 112, a telescopic rod 113, a second connecting plate 114, and a support spring 115. The first connecting plate 111 is fixedly connected to the surface of the mounting base 1, the second connecting plate 114 is fixedly connected to the surface of the second mounting plate 3, the positioning cylinder 112 is fixedly connected to the surface of the first connecting plate 111, the telescopic rod 113 is fixedly connected to the surface of the second connecting plate 114, and the telescopic rod 113 is slidably connected to the inside of the positioning cylinder 112. The support spring 115 is sleeved on the surfaces of the telescopic rod 113 and the positioning cylinder 112, and the two ends of the support spring 115 abut against the surfaces of the first connecting plate 111 and the second connecting plate 114, respectively.

[0035] Specifically, during installation, the elastic element 11 fixes the first connecting plate 111 to the surface of the mounting base 1 with screws, and fixes the second connecting plate 114 to the second mounting plate 3.

[0036] During use, the mounting base 1 pushes the first connecting plate 111 and the positioning cylinder 112 to the right. At this time, the positioning cylinder 112 slides to the right on the surface of the telescopic rod 113 to position the second mounting plate 3 and compress the support spring 115. Conversely, when the mounting base 1 moves to the left, it pulls the first connecting plate 111 and the positioning cylinder 112 to the left, and the support spring 115 will unfold.

[0037] The working principle of this utility model is as follows: The first pneumatic gripper 26 clamps the product part 41, and the second pneumatic gripper 35 clamps the sprue waste 42. During the feeding process, the elastic element 11 works together to automatically separate the product part 41 and the sprue waste 42, effectively improving the feeding and sprue waste 42 separation efficiency, thereby improving the product production efficiency. At the same time, the positioning block 25 cooperates with the first fixed seat 22 to drive the first pneumatic gripper 26 to slide up and down on the surface of the first mounting plate 2, which facilitates the adjustment of the position of the first pneumatic gripper 26. The number of the first pneumatic grippers 26 can be added or reduced at will, which is convenient for use with different numbers of product parts 41 and improves the adaptability of the equipment.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
