Description
Technical Field
[0001] This utility model mainly relates to the field of injection molding production equipment technology, specifically to a suction cup type unloading and gripping robot for injection molding parts. Background Technology
[0002] In the field of injection molding, after the injection molded parts are formed, the unloading operation needs to be completed from the material unloading port of the injection molding machine. Traditional unloading often relies on manual material unloading, which is not only inefficient, but also prone to damage to the injection molded parts or deviation of the material unloading position due to the instability of manual operation.
[0003] While some existing robotic arms can automate material handling, they suffer from problems such as insufficient motion precision, poor adaptability of suction cups to injection molded parts of different shapes, difficulty in stably gripping diverse injection molded parts, and inaccurate limiting mechanisms. These issues result in low gripping reliability and affect the smoothness of subsequent production processes.
[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0021] See attached document Figure 1-4 A suction cup type gripper for injection molded parts includes a base frame 1. A transverse cylinder 2 is provided at the upper end of the base frame 1. Transverse shafts 3 are provided on both sides of the transverse cylinder 2. A gripper mounting frame 4 is connected to the end of the transverse shafts 3. A longitudinal cylinder 5, two linear slide rails 6 and a longitudinal mounting tube 7 are provided on the side of the gripper mounting frame 4 near the transverse cylinder 2. A suction cup module 8 is provided on one side of the two longitudinal mounting tubes 7. A limiting mechanism 15 is provided at the rear end of the suction cup module 8.
[0022] One end of each of the two transverse shafts 3 is connected as a whole by a cylinder connecting bracket 9, so that the driving force of the transverse cylinder 2 can be synchronously transmitted to the two transverse shafts 3. Bearings A10 and B11 are sleeved on the transverse shafts 3. The lower ends of the two bearings are fixedly connected to the base frame 1. The bearings provide support, ensuring that the transverse shafts 3 can slide smoothly in the lateral direction and providing stable support for the transverse shafts 3. The limiting ring 16 between bearings A10 and B11 can limit the axial position of the bearings, preventing the bearings from moving on the transverse shafts 3 and further improving the stability of the transverse shafts 3 during movement.
[0023] The transverse cylinder 2 is fixed on the base frame 1 and is located in the middle of the two transverse shafts 3. Its telescopic end is connected to the cylinder connecting frame 9. When the transverse cylinder 2 extends or retracts, it will drive the two transverse shafts 3 to move laterally in sync through the cylinder connecting frame 9. This will cause the claw mounting frame 4, which is fixedly connected to the transverse shafts 3, to also move laterally. This will enable the claw mounting frame 4 to adjust its position in the transverse direction and provide a suitable transverse station for subsequent gripping of injection molded parts.
[0024] The gripper mounting frame 4 is equipped with a slider 12 corresponding to the linear slide rail 6. The linear slide rail 6 is installed on the side of the gripper mounting frame 4. The slider 12 and the linear slide rail 6 form a sliding engagement, providing precise guidance for the subsequent longitudinal movement of the gripper mounting frame 4, ensuring that no deviation occurs during the longitudinal movement, and improving the movement accuracy.
[0025] The lower ends of the two longitudinal mounting tubes 7 are fixedly connected by the transverse mounting tube 13 to form a stable frame structure. The telescopic end of the longitudinal cylinder 5 is connected to the transverse mounting tube 13. A wedge block 14 is also provided on the transverse mounting tube 13. The wedge block 14 is correspondingly set with the stop block 1502 in the limiting mechanism. When the longitudinal cylinder 5 performs telescopic action, it will push the transverse mounting tube 13 to move along the direction of the linear slide rail 6, thereby driving the two longitudinal mounting tubes 7 to perform longitudinal linear motion synchronously. This allows the suction cup module 8 installed on one side of the longitudinal mounting tube 7 to achieve longitudinal position adjustment, so as to approach or move away from the injection molded part and complete the gripping or releasing action.
[0026] The suction cup module 8 consists of a suction cup frame 801, on which multiple sets of suction cups A802, B803 and C804 are installed. These three types of suction cups are of different sizes and are arranged in a spaced-out manner. Different types of suction cups can be used to target different shape features of injection molded parts. By using a combination of multiple suction cups, the injection molded parts can be gripped more firmly and stably, meeting the requirements for gripping reliability when the injection molded parts are unloaded.
[0027] The limiting mechanism 15 is fixed to the lower end of the claw mounting frame 4 via the connecting plate 1503. It includes a limiting push cylinder 1501 and a stop block 1502. When the suction cup module 8 moves to the preset gripping or placing position under the drive of the longitudinal cylinder 5, the limiting push cylinder 1501 will drive the stop block 1502 to push out and block the wedge block 14, thereby limiting and blocking the suction cup module 8 in the height direction, preventing the suction cup module 8 from deviating due to excessive movement, thus ensuring the positional accuracy of the injection molded part gripping and unloading operation, and improving the accuracy and stability of the entire unloading process.
[0028] The suction cup-type unloading and gripping robot in this embodiment is used to grip the finished injection-molded products inside the injection molding machine. The specific operating steps are as follows: First, the stop block 1502 of the limiting mechanism 15 retracts, releasing the wedge block 14; the longitudinal cylinder 5 starts, pushing the transverse mounting tube 13 and the longitudinal mounting tube 7 to move longitudinally along the linear slide rail 6, driving the suction cup module 8 to adjust its height and precisely run to the height position corresponding to the injection molding machine's material pick-up port. Subsequently, the transverse cylinder 2 is activated, driving the two transverse shafts 3 to move through the cylinder connecting frame 9, causing the claw mounting frame 4 to slide laterally, and smoothly pushing the suction cup module 8, which has been adjusted in height, into the injection molding machine's feeding port. Bearings A10, B11, and the limit ring 16 ensure the stability and accuracy of the transverse movement. Finally, the suction cups A802, B803, and C804 on the suction cup frame 801 work together to adsorb the injection molded product in the material pick-up port. The combination of different suction cups firmly grasps the product and completes the material pick-up action. After the material is picked up, the suction cup module 8 is reset, and the limiting mechanism 15 assists in positioning to ensure that the suction cup module 8 maintains a stable height during unloading.
[0029] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
