Description

Technical Field

[0001] This utility model relates to the field of insert injection molding technology, and in particular to a multifunctional hardware insert embedding mechanism. Background Technology

[0002] In traditional insert injection molding processes, the assembly and injection molding of metal inserts require multiple steps involving both manual assistance and mechanical coordination. Specifically, firstly, a specialized robotic arm must precisely grasp the metal part of a pre-defined specification. This process relies on the positioning accuracy and grasping stability of the robotic arm to prevent the metal part from slipping or shifting position. Subsequently, the robotic arm must smoothly transfer the metal part to the designated insertion station of the injection mold, ensuring that the metal part fits perfectly into the mold cavity. Afterward, the mold closes and the injection molding operation begins, with the molten plastic material encapsulating the metal part to form a one-piece product.

[0003] After injection molding, the product needs to go through demolding, unloading, and other processes before being transferred to the subsequent inspection stage. Inspection personnel must use specialized tools to check each metal insert on the product, focusing on whether any inserts are missing or misaligned. However, this "production first, inspection later" model has significant drawbacks: First, defective products can only be discovered after all processes are completed, making timely intervention during injection molding impossible. This leads to an accumulation of defective products, increasing raw material waste and rework costs, and potentially causing quality disputes as defective products flow into downstream processes. Second, the inspection stage is disconnected from the production process, requiring additional manpower and time costs. Furthermore, the delayed feedback of inspection results makes it difficult to quickly adjust production parameters, severely restricting the overall efficiency of the production line and failing to meet the demands of large-scale, high-efficiency production.

[0004] Therefore, it is necessary to develop a multifunctional hardware insert embedding mechanism to solve the above-mentioned problems. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1 to 5As shown, a multifunctional hardware insert embedding mechanism includes a base 1, a detection fixture 2, and a material handling fixture 3. The detection fixture 2 includes a first mounting plate 21, a second mounting plate 22, a mounting crossbar 23, a material loading protrusion 24, a proximity sensor 25, and a metal sensor 26. The first mounting plate 21 and the second mounting plate 22 are respectively fixed on the left and right sides above the base 1. The right end of the mounting crossbar 23 is fixed to the left end face of the first mounting plate 21. The material loading protrusion 24 is fixed to the left end of the mounting crossbar 23. The proximity sensor 25 is fixed on the mounting crossbar 23, and its sensing end is flush with the left end face of the mounting crossbar 23. The metal sensor... The metal sensor 26 is fixed on the second mounting plate 22 and its sensing end protrudes from the right end face of the second mounting plate 22. Multiple sets of mounting crossbars 23, loading protrusions 24 and proximity sensors 25 are set on the first mounting plate 21. Multiple sets of metal sensors 26 are set on the second mounting plate 22 and correspond one-to-one with multiple sets of mounting crossbars 23. The material handling fixture 3 includes a mounting bracket 31, a connecting plate 32, a product handling component 33 and an insert handling component 34. The connecting plate 32 is fixed above the mounting bracket 31 and is used to connect with the movable end of the robot arm. The product handling component 33 and the insert handling component 34 are respectively fixed on the left and right sides of the mounting bracket 31.

[0021] Before the insert injection molding, the material handling fixture 3 is fixed to the movable end of the robot arm via the connecting plate 32. The metal inserts are manually placed onto the loading protrusion 24. The proximity sensor 25 senses the metal inserts to prevent any missing or improperly placed inserts. After confirming all metal inserts are in place, the robot arm drives the mounting bracket 31 to the left side of the first mounting plate 21, then moves it to the right. The insert handling assembly 34 picks up all the metal inserts from the loading protrusion 24. Next, the robot arm moves the mounting bracket 31 into the injection mold, positioned between the moving and fixed molds. The robot arm continues to drive the mounting bracket 31 to the right, and the insert handling assembly 34 places the five inserts in their corresponding positions on the fixed mold. Then, the insert... The mounting bracket 31 moves to the left, and the product picking component 33 picks up the injection molded product from the moving mold. Driven by the robot, the injection molded product is moved to the right end of the second mounting plate 22. Then, the mounting bracket 31 moves to the left, so that the metal inserts on the injection molded product are fitted onto the sensing end of the metal sensor 26, thereby detecting whether the five inserts on the injection molded product are present and in accurate position, preventing the metal inserts from falling off or shifting from the fixed mold during the injection process. After the injection molded product is found to be without problems, the robot moves the injection molded product to the unloading conveyor belt and transports it to the next process. Then, the robot continues to drive the picking fixture 3 to pick up the metal inserts for the next time, while the injection mold performs the next set of injection processes, and so on. The advantages of this design are: it can grasp and inspect hardware inserts to ensure correct grasping; after injection molding, it can inspect the finished product to prevent missing or incorrectly positioned hardware inserts; it can promptly inspect the inserts after injection molding, quickly adjust production parameters, avoid defective products flowing into downstream processes and causing quality disputes, reduce raw material waste and rework costs, reduce additional manpower and time costs, and improve production efficiency and product qualification rate.

[0022] The product picking assembly 33 includes a pushing cylinder 331, a suction cup mounting plate 332, a first elastic telescopic member 333, a picking suction cup 334, a guide post 335, and a guide sleeve 336. The pushing cylinder 331 is fixed on the mounting bracket 31, with its power output end protruding from the left side of the mounting bracket 31. The suction cup mounting plate 332 is fixed on the power output end of the pushing cylinder 331. The first elastic telescopic member 333 is fixed on the suction cup mounting plate 332. The picking suction cup 334 corresponds to the left side of the suction cup mounting plate 332 and is fixed to the elastic telescopic end of the first elastic telescopic member 333. Multiple sets of the first elastic telescopic member 333 and the picking suction cup 334 are arranged on the suction cup mounting plate 332. The guide sleeve 336 is fixed on the left side of the mounting bracket 31. The left end of the guide post 335 is fixed on the right side of the suction cup mounting plate 332, and the right end of the guide post 335 is slidably connected to the guide sleeve 336.

[0023] When the product is removed from the moving mold, the moving mold ejector pin pushes the injection molded product out. The robot arm drives the mounting bracket to move to the left and approach the product. The push cylinder 331 drives the suction cup mounting plate 332 to move to the left. After the material suction cup 334 contacts the product, the first elastic telescopic member 333 is compressed. All material suction cups 334 adsorb the product. Then, the push cylinder 331 resets, and the robot arm removes the product. The guide post 335 and the guide sleeve 336 cooperate to ensure that the suction cup mounting plate 332 moves stably in the horizontal direction. When inspecting the injection molded product, the robot arm moves the injection molded product to the right side of the second mounting plate 22. The push cylinder 331 drives the product to move to the left. The metal inserts on the product are fitted onto the metal sensor 26. The metal sensor 26 senses whether there are inserts on the injection molded product and whether the position of the inserts is accurate, thereby completing the inspection.

[0024] The insert picking assembly 34 includes a first fixing block 341, a clamping cylinder 342, a clamping block 343, a second fixing block 344, a second elastic telescopic member 345, and a push block 346. The first fixing block 341 is fixed to the right side of the mounting bracket 31. The clamping cylinder 342 is fixed on the first fixing block 341. Two sets of clamping blocks 343 are provided and are respectively fixed on the two sets of power output ends of the clamping cylinder 342. The left end of the second fixing block 344 is fixed on the clamping cylinder 342. The right end of the second fixing block 344 is provided with a connecting boss 3441, which corresponds to the two sets of clamping blocks 343. The left end of the second elastic telescopic member 345 is fixed on the connecting boss 3441 and the elastic telescopic end faces to the right. The push block 346 is fixed to the elastic telescopic end of the second elastic telescopic member 345. The insert picking assembly 34 is provided with multiple sets on the mounting bracket 31 and corresponds one-to-one with multiple sets of picking protrusions 24.

[0025] When the material handling assembly picks up the material from the loading protrusion 24, the clamping cylinder 342 first drives the two sets of clamping blocks 343 to open. At the same time, the second elastic telescopic member 345 is in the extended state. Then, the robot drives the mounting bracket 31 to move to the right. After the push block 346 contacts the left end face of the metal insert, the second elastic telescopic member 345 is compressed to a certain length. Then, the clamping cylinder 342 drives the two sets of clamping blocks 343 to close, clamping the metal insert. The robot drives the mounting bracket 31 to move to the left. At this time, since the metal insert is clamped by the clamping blocks 343, the second elastic telescopic member 345 is still in the compressed state. The robot moves the metal insert to the left side of the fixed mold. Then, the clamping cylinder 342 drives the two sets of clamping blocks 343 to open. The second elastic telescopic member 345 returns to the extended state and is inserted into the designated position in the fixed mold by the push block 346, thus completing the loading of five inserts.

[0026] Both sets of clamping blocks 343 have arc-shaped grooves 3431 on their inner sides, and the radius of the arc-shaped grooves 3431 matches the radius of the hardware inserts.

[0027] Both sets of clamping blocks 343 have arc-shaped grooves 3431 on their inner sides, which can make the hardware inserts more secure when gripping them, prevent the hardware inserts from shifting, and improve the stability of production.

[0028] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the technical scope of this utility model.
