Description

Technical Field

[0001] This utility model relates to a robotic arm for injection molding production. Background Technology

[0002] After injection molding, the workpiece is typically removed from the injection molding machine by a robotic arm. The robotic arm then moves the workpiece above the conveyor line, where it releases the workpiece, which falls onto the conveyor surface under gravity and is then transported to the target area. Currently, existing robotic arms used in injection molding production typically employ a drive mechanism that moves two clamping plates closer together or further apart to grip the injection molded part.

[0003] However, existing robotic arms used in injection molding production have the following problems in practical use: when the robotic arm grips a workpiece with a hollow internal structure, it is prone to damage due to deformation caused by compression, which affects production yield. Therefore, it is necessary to design corresponding technical solutions to solve the above problems. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a robotic arm for injection molding production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a robot for injection molding production, including a robot body, a mounting plate, a contoured inner support, and a clamping mechanism.

[0006] The mounting plate is connected to the output end of the robotic arm body;

[0007] The contoured inner support is located at the bottom of the mounting plate;

[0008] The clamping mechanism includes a drive motor, a lead screw, and two contour clamping plates. The drive motor is located on the top of the mounting plate. One end of the lead screw is connected to the output shaft of the drive motor via a coupling. The two contour clamping plates are located on both sides of the contour inner support member. The two contour clamping plates are slidably connected to the mounting plate via sliding grooves. The top ends of the two contour clamping plates extend above the mounting plate and are threadedly connected to the lead screw via threaded holes. The threads of the threaded holes of the two contour clamping plates have opposite directions.

[0009] Preferably, the contoured inner support is fixedly connected to the mounting plate by screws.

[0010] Preferably, the drive motor is fixedly connected to the mounting plate via a motor mount.

[0011] Preferably, the output end of the robotic arm body is fixedly connected to the mounting plate via a connecting frame, and the connecting frame has an inverted U-shaped structure.

[0012] Preferably, the drive motor is a servo motor.

[0013] The advantages and beneficial effects of this utility model are as follows: It provides a robot for injection molding production with a reasonable structure. By setting a contoured inner support to support the inner side of the workpiece, and by using a clamping mechanism to clamp and fix the outer side of the workpiece, the workpiece can be shaped and clamped, thereby avoiding the deformation of the workpiece due to clamping and squeezing, thus ensuring production yield. Furthermore, the contoured inner support is fixedly connected to the mounting plate with screws, so as to facilitate the assembly and disassembly of the contoured inner support. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0016] The specific technical solution of this utility model is as follows:

[0017] like Figure 1 As shown, a robotic arm for injection molding production includes a robotic arm body, a mounting plate 2, a contoured inner support 3, and a clamping mechanism;

[0018] The mounting plate 2 is connected to the output end 1 of the robotic arm body;

[0019] The contoured inner support 3 is disposed at the bottom of the mounting plate 2;

[0020] The clamping mechanism includes a drive motor 4, a lead screw 5, and two contour clamping plates 6. The drive motor 4 is located on the top of the mounting plate 2. One end of the lead screw 5 is connected to the output shaft of the drive motor 4 via a coupling 7. The two contour clamping plates 6 are located on both sides of the contour inner support 3. The two contour clamping plates 6 are slidably connected to the mounting plate 2 via sliding grooves 8, and the top ends of the two contour clamping plates 6 extend above the mounting plate 2 and are threadedly connected to the lead screw 5 via threaded holes. The threads of the threaded holes of the two contour clamping plates 6 are in opposite directions.

[0021] Furthermore, the contoured inner support 3 is fixedly connected to the mounting plate 2 by screws 9.

[0022] Furthermore, the drive motor 4 is fixedly connected to the mounting plate 2 via the motor base 10.

[0023] Furthermore, the output end 1 of the robotic arm body is fixedly connected to the mounting plate 2 via a connecting frame 11, which has an inverted U-shaped structure.

[0024] Furthermore, the drive motor 4 is a servo motor.

[0025] The working principle of the robotic arm for injection molding production according to this utility model is as follows:

[0026] In use, the robot arm first moves the mounting plate 2, causing the contouring inner support 3 connected to the mounting plate 2 to extend into the workpiece 100 from the top opening. Two contouring clamps 6 are located on both sides of the workpiece 100. The outer wall shape of the contouring inner support 3 matches the inner wall shape of the workpiece 100, and the inner side shape of the contouring clamps 6 matches the outer wall shape of the workpiece 100. Then, the drive motor 4 is controlled to run and drive the lead screw 5 to rotate. The lead screw 5, through its threaded engagement with the two contouring clamps 6, moves the two contouring clamps 6 towards each other and clamps the workpiece 100. During this process, the contouring inner support 3 can support the inner side of the workpiece 100, thereby preventing the workpiece 100 from being deformed due to clamping and squeezing, thus achieving the shaping and clamping of the workpiece 100. Finally, the robot arm moves the mounting plate 2, thereby transporting the clamped workpiece 100 to the designated location.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
