[0002] During the injection molding process, in order to reduce the subsequent assembly process, improve production efficiency and ensure product quality, it is usually necessary to insert inserts into the mold. Commonly used inserts include special structural parts such as thin-walled pipes. Due to their thin wall thickness and light weight, these pipes are more likely to deform or be damaged during the loading and positioning process, and have higher requirements for loading equipment.

[0003] In the prior art, inserts are usually clamped by mechanical clamping for loading. This method relies on the clamping force exerted by the clamping jaws to complete the grasping and movement of the inserts. However, the inserts are thin and have poor deformation resistance. During the clamping process, they are easily deformed or even damaged due to the squeezing of the clamping jaws, which seriously affects the product quality. Summary of the invention

[0029] Please refer to Figure 1 , an inlay suction device provided in an embodiment of the present invention comprises a base 2, a suction assembly 1, a driving assembly 3 and a vacuum suction assembly. Among them, the suction assembly 1 can be movably mounted on one end of the base 2 for sucking inlays. The suction assembly 1 is connected to the base 2 through the driving assembly 3, and the driving assembly 3 is mounted on the other end of the base 2 for driving the suction assembly 1 to pass through the base 2 to contact the inlays. In this embodiment, the driving assembly 3 is a cylinder, and during the suction process, the cylinder can push the suction assembly 1 out of the base 2. The vacuum suction assembly is connected to the suction assembly 1, and is used to generate a stable adsorption force when the suction assembly 1 contacts the inlay. Specifically, the vacuum suction assembly can directly apply the adsorption force to the surface of the inlay through the suction assembly 1, thereby achieving efficient suction of the inlay. In this way, the deformation or damage of the inlay that may be caused by the traditional mechanical clamping method is effectively avoided, and the stability of the suction process is improved. In addition, by controlling the stroke of the cylinder, when the cylinder is extended to the limit stroke, the suction assembly 1 can be pushed to a position that can just adsorb the inlay, thereby ensuring the rapidity and accuracy of the suction operation and improving the feeding efficiency.

[0030] Preferably, the suction assembly 1 includes a mounting panel 11, a plurality of positioning sleeves 12, a suction tube 13 and a positioning plate 14. The plurality of positioning sleeves 12 are all arranged on the mounting panel 11, the positioning plate 14 is connected to the mounting panel 11, the end of the positioning plate 14 close to the panel abuts against the positioning sleeve 12, the suction tube 13 can be movably installed in the positioning sleeve 12, the positioning sleeve 12 guides the movement of the suction tube 13 and limits the radial displacement of the positioning sleeve 12, so as to ensure that the suction tube 13 can be accurately moved to the adsorption position. Specifically, the suction tube 13 is composed of a tube body 131 and a suction head 132, wherein the tube body 131 is movably arranged inside the positioning sleeve 12. The suction head 132 is fixed at one end of the tube body 131, and the other end thereof is away from the tube body 131, and at least partially extends through the positioning plate 14, and can be accurately contacted with the insert under the push of the cylinder, and the insert is adsorbed by the adsorption force generated by the vacuum suction assembly.

[0031] In this embodiment, a plurality of suction components 1 are provided, and a plurality of suction tubes 13 are installed on the mounting panel 11 of each suction component 1 through a positioning sleeve 12. By integrating the plurality of suction tubes 13 on the mounting panel 11, the suction component 1 can absorb a plurality of inserts at one time, thereby significantly improving work efficiency. At the same time, through the above-mentioned modular design, each suction component 1 can be used as an independent functional unit, and can be flexibly configured through quick disassembly and assembly when needed. For example, when the suction volume needs to be increased, the suction capacity can be expanded by increasing the number of suction components 1; and when the inserts in a specific area need to be sucked, one of the suction components 1 can also be used alone. In addition, according to the layout of the inserts, the distance between the suction components 1 can also be fine-tuned, so as to flexibly adapt to the arrangement of different inserts.

[0032] In this embodiment, the vacuum suction component is a vacuum pump, and it can also be a negative pressure generator, an adsorption fan, etc. The vacuum pump has strong and stable adsorption force, and can run continuously for a long time, which is suitable for high-frequency operations. The negative pressure generator has a fast response speed and can quickly establish a vacuum. At the same time, it relies on pneumatic drive, does not require electricity, has high safety, and is suitable for flammable and explosive environments. The adsorption fan is suitable for scenes that require a larger adsorption area and a low vacuum degree. Those skilled in the art can select the above-mentioned equipment as a vacuum suction component according to actual needs, but are not limited to this, as long as it can generate a stable adsorption force and act on the insert through the suction component 1.

[0033] It should be noted that when the insert is a thin-walled tube, due to its small top surface area, if the top surface suction method is adopted, the suction failure may occur due to the small suction surface, which not only affects the work efficiency, but also may cause the failure of the automation equipment. Therefore, in this embodiment, the position where the suction tube 13 sucks the insert is designed to be the side of the insert. Since the side of the insert usually has a larger contact area, side suction can provide a more stable suction effect, effectively avoiding the situation where the suction force is insufficient due to insufficient top surface suction area. In addition, by adopting the side suction design, the problem of adsorption failure caused by the irregular shape of the top surface of the insert or the insufficient surface flatness can also be avoided, thereby significantly improving the reliability and efficiency of adsorption, and providing guarantee for the stable operation of the automation equipment.

[0034] In the above embodiment, although the suction tube 13 is pushed to contact the insert by the driving component 3 to absorb the insert, after the loading is completed, in order to prevent the suction tube 13 from continuously adsorbing the insert and affecting the normal embedding operation, it is necessary to stop the adsorption and reset the suction tube 13 to the initial position. Figure 3As shown, in this embodiment, the suction assembly 1 further includes a reset portion 15 disposed at one end of the tube body 131 away from the suction head 132 and an elastic reset member 16 sleeved on the tube body 131. One end of the reset member 16 abuts against the reset portion 15, and the other end abuts against the positioning sleeve 12. After the suction is completed, the elastic action of the reset member 16 can push the tube body 131 back to the initial position, thereby quickly resetting the suction tube 13 and stopping the suction operation to avoid affecting the subsequent inlay process.

[0035] In this embodiment, the reset member 16 can be a spring, or a rubber sleeve or bellows with elastic properties, but is not limited thereto. The spring has the characteristics of simple structure and strong elastic recovery force, and is suitable for scenarios with high requirements for precise displacement during the reset process of the suction tube 13; the rubber sleeve has good buffering performance and durability, and is suitable for application scenarios that require additional protection during the suction process; the bellows has good flexibility and fatigue resistance, and is suitable for working conditions with frequent reset operations.

[0036] In order to further improve the accuracy of the movement of the suction tube 13, the suction tube 13 also includes a guide ring 133 arranged along the radial direction of the tube body 131. The positioning plate 14 is provided with a guide cavity 141, and the guide ring 133 is installed in the guide cavity 141. Through the cooperation between the guide ring 133 and the guide cavity 141, the movement of the suction tube 13 can be effectively constrained to prevent it from deflecting or shaking, and ensure that it moves smoothly along the predetermined trajectory. In addition, the setting of the guide ring 133 can also disperse the force of the tube body 131 during movement, reduce local stress concentration, and thus extend the service life of the suction tube 13 and related components.

[0037] Preferably, the suction assembly 1 also includes a connecting piece 17, which is arranged at one end of the suction tube 13 away from the guide ring 133, one end of which is connected to the vacuum suction assembly, and the other end is connected to the pipe in the tube body 131. The suction force generated by the vacuum suction assembly is effectively transmitted to the suction tube 13 through the pipe, thereby realizing the adsorption and transfer of the insert.

[0038] Since the suction tube 13 may rebound when it is reset, if it is not effectively restricted, excessive rebound may cause the suction tube 13 to collide with the drive assembly 3, thereby affecting the normal operation of the device. Figure 4 As shown, in this embodiment, the positioning sleeve 12 includes a sleeve 121 and a mounting flange 122 disposed at one end of the sleeve 121. The mounting flange 122 is used to fix the sleeve 121 on the mounting panel 11, and the end of the mounting flange 122 away from the sleeve 121 covers the guide cavity 141 and forms a limiting area together with the guide cavity 141. The limiting area is used to limit the axial displacement of the guide ring 133, thereby effectively restricting the movement range of the suction tube 13 and avoiding excessive movement caused by reset rebound.

[0039] In the above embodiment, although the excessive rebound of the suction tube 13 when it is reset is avoided by the limiting area formed by the positioning sleeve 12 and the guide cavity 141, since the mounting flange 122 is arranged between the positioning plate 14 and the mounting panel 11, it will squeeze out a certain gap between the two. This gap may cause the connection between the positioning plate 14 and the mounting panel 11 to be loose, thereby causing the device to loosen during operation, the guiding accuracy of the suction tube 13 to decrease, and even affecting the overall suction effect. Therefore, in this embodiment, a boss is protruding from the middle of the positioning plate 14, and the boss abuts against the mounting panel 11 to firmly fix the two together, while effectively compensating for the gap squeezed between the two by the mounting flange 122, further ensuring the stability of the device and the accuracy of the suction operation.

[0040] Preferably, the positioning sleeve 12 can be a linear bearing, which can provide low-friction and high-precision guiding support for the movement of the suction tube 13, ensuring that the suction tube 13 moves smoothly along the predetermined trajectory. The use of linear bearings can also effectively reduce the shaking or deviation of the suction tube 13 during movement. The positioning sleeve 12 can also be a sleeve 121 with a magnetic material embedded in the inner wall, and the surface of the suction tube 13 is coated with a corresponding magnetic coating to achieve higher-precision guidance through magnetic adsorption force, but it is not limited to this, as long as it can provide high-precision guiding support.

[0041] like Figure 5 As shown, the base 2 includes an upper mounting plate 21, a lower mounting plate 22, and a plurality of columns 23 arranged between the upper mounting plate 21 and the lower mounting plate 22, which are used to connect the two and form a stable support structure. The suction component 1 is installed on the lower mounting plate 22. Through this layout design, not only the installation process of the suction component 1 is simplified, but also the center of gravity of the device as a whole is effectively lowered, and the stability during operation is improved. The upper mounting plate 21 can be used to fix the drive component 3 and other functional components, while the lower mounting plate 22 serves as the installation base of the suction component 1, and is tightly connected to other parts of the base 2 to ensure the overall structural strength of the device and the accuracy of the suction operation.

[0042] Furthermore, a plurality of columns 23 are sleeved with elastic buffers 24, one end of which abuts against the upper mounting plate 21, and the other end of which abuts against the lower mounting plate 22. The buffers 24 can effectively absorb the vibration or impact force generated by the operation of the driving component 3 or the suction component 1, thereby reducing the impact on the overall structure of the base 2 and improving the stability and service life of the device. In addition, the setting of the buffers 24 can also reduce the noise level during operation, further optimizing the user experience of the device.

[0043] Preferably, the base 2 further comprises a support plate 25 disposed on one end of the lower mounting plate 22 close to the upper mounting plate 21, and the driving assembly 3 is mounted on the support plate 25. In addition, positioning holes are respectively provided on the support plate 25 and the upper mounting plate 21 for accurately positioning the driving assembly 3 to prevent the driving assembly 3 from being offset due to vibration or other external forces during operation, thereby ensuring that the driving assembly 3 always maintains a stable working state, thereby improving the accuracy of the suction operation.

[0044] The present invention also provides an insert feeding device, comprising the insert suction device mentioned above.

[0045] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
