[0048] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] Injection molding production lines occupy an important position in the plastics processing industry, covering many production links from heating and melting of plastic particles to injection molding, cooling, demoulding and subsequent post-processing.

[0050] In related technologies, injection molding production lines can realize automated raw material processing, injection molding operations and product molding, achieving a fully automated production process from raw materials to finished products, which improves production efficiency and raw material utilization, and reduces labor input.

[0051] However, the current layout of injection molding production lines lacks sufficient rationality and optimization, and occupies a large space, which is not conducive to space saving.

[0052] Therefore, the application provides an injection molding part production line, which realizes the effects of saving space and reducing site occupation area by improving the arrangement positions of a conveying device, an injection molding machine and a device placement area, and reasonably planning the placement position of a first grabbing mechanism.

[0053] The injection molding part production line 10 of the application will be described below in combination with the drawings.

[0054] As shown in Figures 1 to 3 , the embodiment of the injection molding part production line 10 includes a conveying device 100, an injection molding machine 200, a device placement area 300 and a first grabbing mechanism 400.

[0055] The conveying device 100 is used for conveying materials, and has a feeding end 101 and a discharging end 102. The conveying device 100 provides a material flow channel for the entire injection molding part production line 10, and ensures that the materials can smoothly reach each required process position (the discharging end 102) from the starting point (the feeding end 101) according to the production process, and it is the link connecting different production links. In the injection molding part production, different processes need the materials to move between different devices and areas, and the conveying device 100 can realize such orderly connection and ensure the continuity of production.

[0056] The injection molding machine 200 is arranged on one side of the conveying device 100, and is the core device of the entire injection molding part production. The function of the injection molding machine 200 is to heat and melt the raw materials such as plastic particles, and then inject the molten plastic into a mold for molding operation through pressure.

[0057] The device placement area 300 is arranged at intervals with the conveying device 100 and located on the side of the injection molding machine 200 away from the conveying device 100, and the conveying device 100, the injection molding machine 200 and the device placement area 300 enclose a placement space. The device placement provides a placement area for other devices, tools or auxiliary devices, and in the entire production line layout, the device placement area 300 helps to reasonably plan the production space, so that different devices and areas can be orderly combined together, which is convenient for production operation, device maintenance and material flow, etc.

[0058] As shown in Figure 1 and Figure 2 , the first grabbing mechanism 400 is arranged in the placement space, and the first grabbing mechanism 400 can take and place materials in a first grabbing range 401, the first grabbing range 401 covers at least part of the conveying device 100, at least part of the injection molding machine 200 and at least part of the device placement area 300, which ensures that the materials can be accurately transferred between different devices and areas.

[0059] For example, the first gripping mechanism 400 can grab materials from the conveying device 100 and then place them in the injection molding machine 200 for injection molding, or remove the molded product from the injection molding machine 200 and place it in a suitable location. The first gripping range 401 covers at least a portion of the conveying device 100, at least a portion of the injection molding machine 200, and at least a portion of the device placement area 300, which enables it to effectively integrate the material flow between different equipment in this specific production area, thereby improving the degree of automation and production efficiency of the entire injection molding production line 10. At the same time, the first gripping mechanism 400 is placed in the placement space surrounded by the conveying device 100, the injection molding machine 200, and the device placement area 300, which saves space while ensuring the optimization of the moving path of the first gripping mechanism 400, making the layout of the production line more optimized and reasonable.

[0060] It should be noted that the above-mentioned “first grasping range 401 ” refers to the maximum movable range of the first grasping mechanism 400 .

[0061] In some embodiments, the first gripping mechanism 400 may be a robotic arm structure. For example, the first gripping mechanism 400 may include a first mounting base 410 and a first robotic arm 420 rotatably mounted on the first mounting base 410 . The first robotic arm 420 may be capable of picking up and placing materials within a first gripping range 401 .

[0062] The first grasping range 401 is a sector (the rotatable angle of the first robotic arm 420 is less than 360°) or a circle (the rotatable angle of the first robotic arm 420 is 360°) formed with the rotation center of the first robotic arm 420 as the center and the maximum grasping distance of the first robotic arm 420 as the radius.

[0063] It should also be noted that, in some embodiments, the first robotic arm 420 includes a gripping portion for picking up and placing materials. The first robotic arm 420 has a starting position. When the first robotic arm 420 is in the starting position, the gripping portion of the first robotic arm 420 is located between the injection molding machine 200 and the first mounting base 410.

[0064] This starting position helps optimize the material's movement path within the injection molding machine 200. During the injection molding process, the injection molding machine 200 is a core component that frequently moves materials. The first robotic arm 420's rotating end is mounted on the first mounting base 410, and the gripping portion returns to the starting position after each operation. This reduces the distance and time required for material movement, thereby improving production efficiency.

[0065] Furthermore, if Figure 1As shown, in some embodiments, the conveying device 100 includes a frame 110 , a conveyor belt 120 and a first driving device 130 . The conveyor belt 120 is disposed on the frame 110 , and the first driving device 130 is drivingly connected to the conveyor belt 120 .

[0066] The frame 110 is the supporting structure of the conveyor device 100, providing stable physical support for the conveyor belt 120, the first drive device 130, and other related components, ensuring that the entire conveyor device 100 maintains a stable structure during operation. The structural design of the frame 110 meets the installation requirements of the conveyor belt 120, ensuring that the conveyor belt 120 can transport materials at an appropriate height and angle. It also provides suitable installation space for the first drive device 130, allowing it to effectively connect to the conveyor belt 120.

[0067] The conveyor belt 120 is mounted on the frame 110 and primarily functions to carry materials. On the injection molding production line 10, the conveyor belt 120 directly contacts the materials, transporting them from the infeed end 101 to the outfeed end 102. This provides a surface for the materials to move, allowing them to move from one process step to another within the production process. Compared to other intermittent transport methods, the continuous operation of the conveyor belt 120 helps ensure the continuity of the injection molding production line 10 and improve production efficiency.

[0068] The first drive device 130 is in driving connection with the conveyor belt 120, and its core function is to provide power for the conveyor belt 120. Through its connection with the conveyor belt 120, the first drive device 130 converts electrical energy or other forms of energy into mechanical energy to drive the conveyor belt 120. The first drive device 130 also controls the speed of the conveyor belt 120. During the injection molding process, the first drive device 130 can adjust the speed of the conveyor belt 120 according to production requirements to meet the material supply speed requirements of each process.

[0069] Further, if Figure 1 As shown, in some embodiments, the injection molding production line 10 further includes a metering device 500, which is disposed on the conveying device 100 and close to the discharge end 102 of the conveying device 100; the first grabbing range 401 covers the upstream and downstream of the metering device 500 in the material conveying direction.

[0070] In the production of injection molded parts, accurate material quantity is essential for product quality. Through the metering device 500, it can be ensured that the material quantity entering the subsequent equipment such as the injection molding machine 200 meets the requirements of the production process, thereby ensuring the quality stability of the injection molded parts. The first grabbing range 401 covers the upstream and downstream of the metering device 500 in the material conveying direction, which enables the first grabbing mechanism 400 to cover the material flow related to the metering device 500. The first grabbing mechanism 400 can accurately grab and place the material into the metering device 500 for metering; and can also grab the metered material and transport it to the next production link, such as the injection molding machine 200, etc.

[0071] Exemplarily, the metering device 500 can include a metering scale.

[0072] As shown in Figure 1 , Figure 4 and Figure 5 , the injection molding machine 200 includes a bearing table 210, an injection mechanism 220, and a feeding mechanism 230. The feeding mechanism 230 is movably arranged on the bearing table 210 and includes a processing station 2311 and a to-be-processed station 2312. The injection mechanism 220 is movably arranged above the feeding mechanism 230 for injecting material into the processing station 2311. The first grabbing range 401 of the first grabbing mechanism 400 covers the to-be-processed station 2312.

[0073] The bearing table 210 serves as an important component of the injection molding machine 200 and provides a support basis for the injection mechanism 220 and the feeding mechanism 230.

[0074] The feeding mechanism 230 is movably arranged on the bearing table 210 and includes a processing station 2311 and a to-be-processed station 2312. Its main function is to provide a placement position for the material according to the function. In the to-be-processed station 2312, the material can be prepared for the early work, such as positioning, preheating, etc. In the processing station 2311, the core operation of injecting and molding is performed. The design of the two stations of the feeding mechanism 230 helps to ensure the orderliness of the injection molding production process. It enables different states of the material to be processed in different stations, avoiding mutual interference between different processes, and at the same time, it is also conducive to improving the production efficiency, because the material preparation can be carried out in one station while the injection molding operation is carried out in the other station.

[0075] The injection mechanism 220 is movably arranged above the feeding mechanism 230 for injecting material into the processing station 2311. Its core function is to accurately inject the molten plastic material into the mold of the processing station 2311.

[0076] The first grabbing range 401 of the first grabbing mechanism 400 covers the to-be-processed work station 2312, which can ensure the supply of materials to the to-be-processed work station 2312. The first grabbing mechanism 400 can grab materials from other areas and place them to the to-be-processed work station 2312, ensuring that the feeding mechanism 230 can obtain materials in time at the to-be-processed work station 2312, thereby maintaining the continuity of the injection molding production process.

[0077] Further, the material injection mechanism 220 comprises a mounting frame 221, a material storage portion 222, a material injection portion, and a second driving structure.

[0078] The mounting frame 221 is movably arranged on the bearing table 210 and serves to integrate the material storage portion 222 and the material injection portion.

[0079] The second driving structure is arranged on the bearing table 210 and drivingly connected with the mounting frame 221, and it is the power source for moving the mounting frame 221. It can provide accurate moving power for the mounting frame 221, so that the mounting frame 221 can accurately move to a specified position according to a preset program or an instruction of an operator.

[0080] The material storage portion 222 and the material injection portion are arranged on the mounting frame 221, and the material storage portion 222 is in communication with the material injection portion, so that the materials in the material storage portion 222 can be directly and rapidly transmitted to the material injection portion.

[0081] Further, as shown in Figure 4 and Figure 5 in some embodiments, the material injection mechanism 220 is movably arranged above the feeding mechanism 230 in the vertical direction. Exemplarily, the material injection portion in the material injection mechanism 220 is movably arranged above the feeding mechanism 230 in the vertical direction.

[0082] Specifically, the feeding mechanism 230 can comprise a rotating disc 231, which is rotatably arranged on the bearing table 210 and has two work stations, one of which located directly below the material injection mechanism 220 is a processing work station 2311, and the other work station located opposite to the material injection mechanism 220 is a to-be-processed work station 2312. This structure design realizes efficient work station switching. When one work station (the processing work station 2311) is performing injection molding operation, the other work station (the to-be-processed work station 2312) can perform material preparation or other pre-operation. Through the rotation of the rotating disc 231, the two work stations can be quickly switched, reducing the waiting time in the production process and improving the overall production efficiency of the injection molding production line.

[0083] In addition, the two-station mode of the rotating disc 231 can realize multiple functions in limited space. It avoids setting a larger space for each process, saving the internal space resources of the injection molding machine 200. At the same time, the relative position relationship of the two stations (one is located directly below the material injection mechanism 220 as the processing station 2311, and the other is staggered as the to-be-processed station 2312) is carefully designed, which not only ensures the smooth operation of the material injection operation, but also facilitates the loading and unloading, pretreatment and other operations of the material in the to-be-processed station 2312, improving the rationality of space utilization.

[0084] As shown in Figure 1 and Figure 3 In some embodiments, the injection molded part production line 10 further includes a second grabbing mechanism 600, which is arranged on the side of the injection molding machine 200 away from the first grabbing mechanism 400. The second grabbing mechanism 600 can take and place materials within a second grabbing range 601, and the second grabbing range 601 covers at least part of the injection molding machine 200.

[0085] The layout mode of the second grabbing mechanism 600 greatly expands the operation range of the injection molded part production line 10. It can cover part of the area of the injection molding machine 200 and complement the first grabbing mechanism 400, so that material taking and placing operations in different directions of the injection molding machine 200 can be realized. For example, when the first grabbing mechanism 400 is responsible for material input on one side of the injection molding machine 200, the second grabbing mechanism 600 can be responsible for output of finished products or semi-finished products on the other side, improving the overall material handling capacity of the production line.

[0086] In some embodiments, the second grabbing mechanism 600 can adopt a mechanical arm type structure. For example, the second grabbing mechanism 600 includes a second mounting seat 610 and a second mechanical arm 620, and the second mechanical arm 620 is rotatably arranged on the second mounting seat 610. The second mechanical arm 620 can take and place materials within the second grabbing range 601.

[0087] The second grabbing range 601 is a sector (the rotatable angle of the second mechanical arm 620 is less than 360°) or a circle (the rotatable angle of the second mechanical arm 620 is 360°) with the center of rotation of the second mechanical arm 620 as the center and the maximum grabbing distance of the second mechanical arm 620 as the radius.

[0088] In some embodiments, the injection molded part production line 10 further includes a heating device 700 for heating the injection molding material. The heating device 700 is arranged within the second grabbing range 601, so that the second grabbing mechanism 600 can timely send the heated material into the injection molding machine 200.

[0089] It should be noted that, as Figure 1As shown, the device placement area 300 can also be provided with one or more of the following devices: a loading platform 800, a guide plate heating device 900, a material return device, and a detection device. The first grasping range 401 covers the devices located in the device placement area 300, so as to facilitate the interaction between the first grasping device and the above-mentioned structure.

[0090] The loading platform 800 provides a temporary storage space for materials, equipment, etc. During the injection molding process, materials and equipment may need to undergo some pre-processing or wait to be grabbed by a grabbing mechanism.

[0091] The guide plate heating device 900 can preheat the guide plate.

[0092] The material return device is used to recycle unqualified materials or residual materials in the production process.

[0093] The inspection device is used to inspect materials or molded parts. During the injection molding process, the inspection device can perform preliminary inspections on materials entering the injection molding machine 200 to ensure they meet production requirements. It can also perform quality inspections on finished or semi-finished products to promptly identify quality issues. This helps improve product quality and reduce defective product rates.

[0094] The injection molding production line of this application makes the production pace more orderly. Through reasonable factory layout planning, the logistics time and distance from raw materials to finished products can be minimized to the greatest extent, improving the efficiency of the production process. Optimizing the logistics process helps reduce waste and bottlenecks in the production process and reduce the cost of the product life cycle. By optimizing the production line layout, errors and defects in the production process can be reduced, and the consistency and quality stability of the product can be improved. A reasonable layout also helps to reduce the impact of human factors on product quality, and provides a better quality control and testing environment, eliminating transportation waste, visualizing the production process, and reducing quality risks.
