Description

Technical Field

[0001] The utility model relates to the technical field of injection molding part detection, in particular to automatic detection equipment for defective injection molding machine accessories. Background Art

[0002] Injection molding machine accessories refer to various injection molding products produced by injection molding machines, collectively referred to as injection molding parts, including various packages, parts, etc. They are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. After the injection molding parts are processed, their surface is uneven, so it is necessary to test their flatness so that unqualified injection molding parts can be removed.

[0003] In the prior art, defective product detection equipment for injection molding machine parts is usually operated by two sets of mechanical arms during use. Figure 1 As shown, a group of robotic arms are used to remove the accessories to be inspected from the conveyor and place them on the inspection table. After the inspection, another group of robotic arms place the inspected accessories on the unloading table. The placement position is determined according to the inspection results to distinguish qualified and unqualified products. However, in actual use, when the robotic arm places the injection molded part on the top of the inspection table, the robotic arm is usually used to maintain the stability of the injection molded part, but the presence of the robotic arm easily blocks the accessories, resulting in blind spots in inspection and certain defects. Therefore, the utility model provides an automatic inspection device for defective injection molding machine accessories to meet the needs. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] An automatic detection device for defective injection molding machine accessories comprises a fixed frame, the top of the fixed frame is connected to a workbench, the top of the workbench is fixedly connected to a detection component for detecting defective products, a transmission mechanism, the transmission mechanism is used to adjust the position of the detection component, the transmission component is connected to the workbench, and a limiting mechanism is used to limit the injection molding machine accessories, and the limiting mechanism is located above the workbench.

[0006] Optionally, a servo motor is fixedly connected to the interior of the fixed frame, a transmission shaft is fixedly connected to the output shaft of the servo motor, and the exterior of the transmission shaft is rotatably connected to a workbench on the top of the fixed frame via a bearing.

[0011] Optionally, the limiting mechanism is an integral injection-molded structure.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:

[0013] In the above scheme, by setting a limit mechanism, the injection molding machine accessories can be placed on the top of the limit mechanism through the robot arm during actual use. The force of the falling accessories will squeeze the fitting parts, and these fitting parts made of elastic materials can fit the accessories tightly, thereby stably limiting them. Due to the design of the limit mechanism, its structure will not block the outer surface of the accessories. At the same time, the motor at the bottom can drive the limit mechanism to rotate, ensuring that the detection component can fully and completely detect the quality parameters such as the flatness of the accessories.

[0014] In the above scheme, due to the design of the hollow cone inclined portion in the limiting mechanism, the limiting mechanism can limit accessories of different sizes. At the same time, the design of the guide portion can enable the accessories to move more smoothly to the outside of the limiting component. The raised portion (semicircular in cross section) can further increase the friction with the injection molded part to prevent sliding. The connecting portion is designed as a ring structure with a M-shaped frame in the center, which enhances the stability and load-bearing capacity of the structure. The limiting mechanism adopts an integrated injection molding structure with a simple overall structure, which reduces the assembly gap between parts, improves the stability and durability of the structure, and reduces costs. At the same time, the integrated injection molding structure also simplifies the maintenance process and reduces maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is a detailed description of an automatic detection device for defective injection molding machine accessories provided by the utility model in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides an automatic detection device for defective injection molding machine accessories, including a fixed frame 1, the top of the fixed frame 1 is connected to a workbench, the top of the workbench is fixedly connected to a detection component 6 for detecting defective products, a transmission mechanism 2, the transmission mechanism 2 is used to adjust the position of the detection component 6, and the transmission mechanism 2 is connected to the workbench; when the robot arm transfers the accessory to the workbench, the detection component 6 can detect the surface of the accessory, and according to the detection result, another robot arm will distinguish and place the accessory.

[0023] In this embodiment, if Figures 1 to 4As shown, a limiting mechanism 5 is used to limit the injection molding machine accessories. The limiting mechanism 5 is located above the workbench. The interior of the fixed frame 1 is fixedly connected to a servo motor 3. The output shaft of the servo motor 3 is fixedly connected to a transmission shaft 4. The exterior of the transmission shaft 4 is rotatably connected to the workbench at the top of the fixed frame 1 through a bearing. The limiting mechanism 5 includes a connecting portion 501 fixedly connected to the top of the transmission shaft 4. The connecting portion 501 is an annular structure, and a M-shaped frame is provided at the center of the connecting portion 501. An inclined portion 502 is provided at the top of the connecting portion 501. The limiting mechanism 5 is an integrated injection molding structure. The exterior of the inclined portion 502 is provided with six annularly distributed fitting portions 504. The fitting portion 504 is made of elastic material. When the robot arm places the injection molding machine accessories on the inclined portion 502, the weight of the accessory itself will cause it to slide down along the inclined surface until it contacts the six annularly distributed fitting portions 504. These fitting parts 504 are made of elastic material and have excellent deformation recovery ability. When there is no injection molding machine accessory placed, the fitting part 504 maintains its original shape and is in an unstressed state. When the fitting part is pressed down by the force of the accessory, the gravity of the accessory will cause the fitting part 504 to be subjected to downward pressure. Since the fitting parts 504 are made of elastic material, they will deform and sag downward to fit the surface of the accessory. This deformation is uniform and reversible, and can quickly return to its original state after the accessory is removed. After the inspection is completed, when the robot arm removes the injection molding machine accessory from the limiting mechanism 5, the pressure on the fitting part 504 disappears. Due to the memory effect of the elastic material, the fitting part 504 can quickly return to its original shape and prepare for the next limiting operation. The servo motor 3 drives the connecting part 501 and the entire limiting mechanism 5 to rotate through the transmission shaft 4 to cooperate with the detection component 6 to perform a full range of inspections on the injection molding machine accessories.

[0024] The inclined portion 502 is a hollow truncated cone structure, and a guide portion 503 is provided on the top of the inclined portion 502. Since the inclined portion 502 is a hollow truncated cone structure, its gradually shrinking diameter can naturally guide the accessory to slide down along the inclined surface until it contacts the fitting portion 504. This design allows accessories with different apertures to be placed smoothly and stably on the limiting mechanism 5. The hollow truncated cone structure allows the inclined portion 502 to maintain a certain overall size while gradually reducing the internal space. Even if the apertures of the accessories vary, the inclined portion 502 can provide enough space for the accessories to fall, and adapt to these differences through the elastic deformation of the fitting portion 504. When the accessories fall and contact the fitting portion 504, due to the guidance of the guide portion 503, the accessories will be placed at a more stable angle and position. This helps to improve the accuracy of the detection component 6 in detecting accessories and reduce misjudgments caused by improper positioning of accessories.

[0025] Four equidistantly distributed protrusions 505 are provided on the outside of the fitting portion 504, and the cross-section of the protrusion 505 is semicircular. The semicircular protrusions 505 can provide additional friction when the accessory contacts the fitting portion 504, which helps prevent the accessory from sliding or shifting during the detection process and ensures that the accessory always remains in a stable position, thereby improving the accuracy and reliability of the detection. Since the protrusions 505 are equidistantly distributed, they can adapt to accessories of different shapes and sizes. When the accessory is placed on the limiting mechanism 5, the protrusions 505 can be deformed according to the shape and size of the accessory to better fit the outer surface of the accessory. This adaptability enables the limiting mechanism 5 to be widely used in various types of injection molding machine accessories. The semicircular protrusions 505 can disperse the impact force generated when the accessory falls and reduce stress concentration. This design helps to extend the service life of the limiting mechanism 5 and reduce wear and damage caused by long-term use.

[0026] The workflow provided by the utility model is that during use, when the robot arm transfers the accessories to the workbench, when the robot arm places the injection molding machine accessories on the inclined portion 502, the weight of the accessories themselves will cause them to slide down along the inclined surface until they contact the six fitting portions 504 distributed in an annular manner. The fitting portions 504 are made of elastic material and have excellent deformation recovery ability. When there is no injection molding machine accessory placed, the fitting portion 504 maintains its original shape and is in an unstressed state. When the fitting portion is pressed down by the force of the accessory, the weight of the fitting will cause the fitting portion 504 to be subjected to downward pressure. Since the fitting portions 504 are made of elastic material, they will deform and sink downward to fit the surface of the accessory. This deformation is uniform and reversible, and can quickly return to its original state after the accessory is removed. After the inspection is completed, when the robot arm removes the injection molding machine accessory from the limiting mechanism 5, the pressure on the fitting portion 504 disappears. Due to the memory effect of the elastic material, the fitting part 504 can quickly restore its original shape to prepare for the next limiting operation. At the same time, the servo motor 3 drives the connecting part 501 and the entire limiting mechanism 5 to rotate through the transmission shaft 4. The detection component 6 can detect the surface of the accessory, and another robotic arm will distinguish and place the accessory according to the detection result.

[0027] It should be noted that the detection component 6 and the transmission mechanism 2 are both existing public technologies, so they are not described in detail.

[0028] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
