Description

Technical Field

[0001] This utility model belongs to the field of injection molding processing technology, specifically relating to a CNC robotic arm for injection molding machines. Background Technology

[0002] The background technology of CNC robotic arms for injection molding machines mainly stems from the deep integration of industrial automation and plastic molding processes. As the injection molding industry's demands for production efficiency, precision, and safety increase, traditional manual part handling and simple mechanical devices are gradually being replaced by programmable CNC robotic arms. Early robotic arms used pneumatic or hydraulic drives, which had limited precision; modern systems integrate servo motors, high-precision sensors, and PLC / CNC control systems, realizing full automation of processes such as mold opening and closing, ejection, part handling, and stacking.

[0003] Traditional clamping mechanisms mostly use fixed grippers, which can only adapt to injection molded parts of specific shapes. When encountering workpieces with curved surfaces, thin walls, or complex structures, problems such as unstable clamping and uneven force often occur, leading to product deformation or surface damage. The existing robotic arms have limited clamping angle adjustment range, making it difficult to meet diverse production needs. Utility Model Content

[0025] Example

[0026] Reference Figures 1-4This is an embodiment of the present invention, which provides a CNC robotic arm for an injection molding machine, comprising:

[0027] The control mechanism 100 includes a control cabinet 101, a cabinet door 102 hinged to the side wall of the control cabinet 101, a mounting plate 103 fixedly installed on the inner wall of the control cabinet 101, a control panel 104 fixedly installed in the inner cavity of the control cabinet 101, and a connector 105 communicating with the surface of the control cabinet 101.

[0028] The moving mechanism 200 includes a support base 201 fixedly connected to the side wall of the control cabinet 101, a connecting plate 202 fixedly installed on the side wall of the support base 201, a slide rail 203 fixedly connected to the top of the support base 201, a drive assembly 204 disposed on the surface of the slide rail 203, and a gripping assembly 205 disposed on the surface of the drive assembly 204.

[0029] Specifically, the drive assembly 204 includes a slider 204a slidably connected to the surface of the slide rail 203, a movable seat 204b fixedly installed on the side wall of the slider 204a, a linear motor 204c adapted to be installed on the side wall of the movable seat 204b, and a first motor 204d fixedly installed on the side wall of the movable seat 204b. The drive assembly 204 also includes a second motor 204e fixedly installed on the surface of the movable seat 204b, a first belt 204f sleeved on the output end of the first motor 204d, and a second belt 204g sleeved on the output end of the second motor 204e.

[0030] Furthermore, the first motor 204d and the first belt 204f work together with the second motor 204e and the second belt 204g to control the travel path of the clamping component 205, making the device easier to use.

[0031] Preferably, the clamping assembly 205 includes a connecting beam 205a fixedly mounted on the side wall of the movable seat 204b, and a guide rail 205b fixedly mounted on the side wall of the connecting beam 205a. The clamping assembly 205 also includes a clamping member 205c movably connected to the surface of the guide rail 205b, and an auxiliary member 205d slidably connected to the surface of the guide rail 205b.

[0032] The clamping component 205c includes a first clamping seat 205c-1 slidably connected to the surface of the guide rail 205b, a first telescopic rod 205c-2 fixedly installed on the side wall of the first clamping seat 205c-1, a third motor 205c-3 adapted to be installed on the side wall of the first clamping seat 205c-1, and a clamper 205c-4 fixedly installed on the side wall of the first clamping seat 205c-1. The auxiliary component 205d includes a second clamping seat 205d-1 slidably connected to the surface of the guide rail 205b, a second telescopic rod 205d-2 fixedly installed on the side wall of the second clamping seat 205d-1, a fourth motor 205d-3 adapted to be installed on the side wall of the second clamping seat 205d-1, a cylinder 205d-4 fixedly installed in the inner cavity of the second telescopic rod 205d-2, and a clamping block 205d-5 connected to the end of the second telescopic rod 205d-2 by a bearing.

[0033] It should be noted that the surface of the first clamping seat 205c-1 is movably connected to the inner wall of the first belt 204f through a bearing, and the surface of the second clamping seat 205d-1 is movably connected to the inner wall of the second belt 204g through a bearing. When the first motor 204d and the second motor 204e are running, the first clamping seat 205c-1 and the second clamping seat 205d-1 can be controlled to slide on the guide rail 205b.

[0034] In use, the control mechanism 100 sets the operating parameters through the control panel 104 and synchronizes the signals with the injection molding machine through the connector 105. During operation, the linear motor 204c drives the slider 204a to move along the slide rail 203 to the top of the mold. At the same time, the first motor 204d and the second motor 204e drive the first clamping seat 205c-1 and the second clamping seat 205d-1 to slide towards each other along the guide rail 205b through the first belt 204f and the second belt 204g, so that the clamping device 205c-4 is aligned with the workpiece. The third motor 205c-3 and the fourth motor 205d-3 work together to drive the second telescopic rod 205d-2 and the third telescopic rod to move up and down. The cylinder 205d-4 can extend and retract to adjust the angle of the clamping block 205d-5. When used with the clamping device 205c-4, the clamping angle can be adjusted to adapt to irregularly shaped workpieces. After clamping, the drive assembly 204 moves the workpiece to the designated position to realize automatic part picking and stacking.

[0035] In summary, the control panel 104 and connector 105 of the control mechanism 100 work together with the injection molding machine to achieve signal linkage and ensure synchronized actions; the support base 201 and slide rail 203 form a stable moving platform, which works with the linear motor 204c to achieve precise positioning; the first motor 204d drives the first clamping seat 205c-1 through the first belt 204f, and the second motor 204e drives the second clamping seat 205d-1 through the second belt 204g, so that the gripper 205c-4 can open and close symmetrically; the third motor 205c-3 controls the lifting and lowering of the first telescopic rod 205c-2, and the fourth motor 205d-3 works with the cylinder 205d-4 to adjust the angle of the clamping block 205d-5, so that the robotic arm can adapt to the gripping needs of workpieces of different shapes; the cooperative design of the connecting beam 205a and the guide rail 205b realizes the smooth sliding of the clamping components. The cooperation of each component enables the robotic arm to complete precise picking and stacking operations, improving production efficiency and operational safety.
