TECHNICAL FIELD

[0001] The application relates to the technical field of injection molding production and processing, and in particular to an injection molding part raw material shearing device. BACKGROUND

[0002] At present, plastic parts, especially large plastic parts such as trays and ceilings, are usually injection molded by injection molding machines. In order to ensure that the injection molded parts can be safely taken out, an automatic material taking manipulator is generally installed on the injection molding machine.

[0003] However, such an automatic material taking manipulator can only realize the function of taking out the injection molded plastic parts and placing them at a specified position, and cannot meet the requirement of removing the rod-shaped raw material on the surface of the injection molded part in subsequent processing. Therefore, additional manual work or special equipment needs to be added to complete this process in the existing production process, resulting in low overall production efficiency, and thus needs to be improved. CONTENT OF THE UTILITY MODEL

[0004] In order to facilitate the cutting of the raw material on the injection molded part, the application provides an injection molded part raw material shearing device.

[0005] The injection molded part raw material shearing device provided by the application adopts the following technical scheme:

[0006] The injection molded part raw material shearing device comprises a material taking manipulator, a support frame, a conveying belt, a shearing assembly and a material discharging manipulator. The support frame is located on one side of an injection molding machine, and the conveying belt is rotatably connected to the support frame. The material taking manipulator is used to take out the injection molded part in the injection molding machine and transfer the injection molded part to the conveying belt. The shearing assembly is arranged on the support frame and located above the conveying surface of the conveying belt. The shearing assembly is used to shear the raw material on the injection molded part. The material discharging manipulator is located close to the output end of the conveying belt and is used to discharge the sheared injection molded part.

[0007] By adopting the above technical scheme, first, the automatic material taking manipulator attached to the injection molding machine takes out the injection molded part formed by injection molding and places it on the conveying belt. Then, the shearing assembly on the support frame cuts the raw material on the surface of the injection molded part. When the rod-shaped raw material on the surface of the injection molded part is completely removed, the conveying belt rotates and drives the injection molded part to travel a certain distance. Finally, the material discharging manipulator takes the injection molded part from the conveying belt and stacks it in the storage area. Through integrated design, manual intervention in the middle link is reduced, automatic continuous production is realized, and the production efficiency of the injection molded part is improved.

[0008] Preferably, the shearing assembly comprises an X-axis guide rail, a Y-axis guide rail, a sliding base, a lifting member and a pneumatic shear, the Y-axis guide rail is arranged on the support frame, the X-axis guide rail is slidably connected to the Y-axis guide rail, the sliding base is slidably connected to the X-axis guide rail, the lifting member is arranged on the sliding base, the pneumatic shear is connected to the lifting member and is used for shearing the raw material, and the lifting member is used for controlling the pneumatic shear to move close to or away from the conveying belt.

[0009] By adopting the above technical scheme, when the injection molded part is stably placed on the conveying belt, the lifting member can be operated to control the pneumatic shear to move downward to be close to the injection molded part, and the pneumatic shear can accurately determine the position of the raw material by means of the positioning sensor, and then the raw material can be cut off.

[0010] In the embodiment, since there is more than one raw material on the surface of the injection molded part, the sliding base can move horizontally along the X-axis direction on the X-axis guide rail, and the entire X-axis guide rail can move horizontally along the Y-axis direction on the Y-axis guide rail, so that the position of the pneumatic shear relative to the injection molded part is changed, and thus the raw material can be cut at multiple positions.

[0011] Preferably, the lifting member is a linear air cylinder, an oil cylinder or an electric push rod.

[0012] By adopting the above technical scheme, the linear air cylinder, the oil cylinder or the electric push rod can be used to control the pneumatic shear to move up and down.

[0013] Preferably, the shearing assembly further comprises a positioning assembly arranged on the support frame and used for positioning the injection molded part.

[0014] By adopting the above technical scheme, when the injection molded part is placed on the conveying belt, the positioning assembly can be used to position and press the injection molded part, so that the stability of the position of the injection molded part is improved, and the position deviation of the injection molded part during the cutting of the raw material by the shearing assembly is avoided.

[0016] By adopting the technical scheme, when positioning the injection molded part, the ejection air cylinder controls the whole connecting frame to move close to the injection molded part, so that the compression roller abuts against the injection molded part and pushes the injection molded part to the positioning roller, and the positioning of the injection molded part is realized by cooperation of the compression roller and the positioning roller, thereby improving the stability of the position of the injection molded part. Meanwhile, when the conveying belt horizontally conveys the injection molded part, since the compression roller and the positioning roller can rotate to realize the rolling friction with the injection molded part, the conveying of the conveying belt is not affected on the premise of ensuring the clamping and positioning of the injection molded part.

[0017] Preferably, a plurality of compression rollers are arranged at intervals along the conveying direction of the conveying belt, and a plurality of positioning rollers are arranged at intervals along the conveying direction of the conveying belt.

[0018] By adopting the technical scheme, the plurality of compression rollers and the plurality of positioning rollers can realize the multi-point contact with the injection molded part, thereby improving the stability when the injection molded part is clamped.

[0019] Preferably, the device further comprises a fixing frame and a suction accessory, the fixing frame is arranged on the blanking manipulator, and the suction accessory is arranged on the fixing frame and is used for suction.

Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0037] This application discloses a shearing device for injection molded parts. (Refer to...) Figures 1 to 3 The shearing device includes a material handling robot 1, a support frame 2, a conveyor belt 3, a shearing assembly 4, and a material unloading robot 5. The material handling robot 1 is an integral part of the injection molding machine. The support frame 2 is located on one side of the injection molding machine, and the conveyor belt 3 is rotatably connected to the support frame 2. The material handling robot 1 is used to remove the injection molded parts from the injection molding machine and transfer them to the conveyor belt 3, which is used for horizontal transport of the injection molded parts. The shearing assembly 4 is mounted on the support frame 2 and located above the conveying surface of the conveyor belt 3. The shearing assembly 4 is located at the conveying end of the conveyor belt 3 and is used to shear the raw material on the injection molded parts. The material unloading robot 5 is located near the output end of the conveyor belt 3 and is used to unload the sheared injection molded parts.

[0038] During production, the automatic material handling robot 1, equipped with the injection molding machine, first precisely removes the injection-molded parts after the injection molding process and places them orderly on the conveyor belt 3. Next, the shearing components 4 on the support frame 2 cut away the rough material on the surface of the injection-molded parts. After the rough material on the surface of the injection-molded parts is completely removed, the conveyor belt 3 starts to operate, thus moving the injection-molded parts forward a certain distance. Finally, the unloading robot 5 removes the injection-molded parts from the conveyor belt 3 and neatly stacks them in the designated storage area. By adopting an integrated design concept, manual intervention in intermediate stages of the production process is significantly reduced, successfully realizing an automated continuous production mode and effectively improving the production efficiency of injection-molded parts.

[0039] Specifically, the shearing assembly 4 comprises an X-axis guide rail 41, a Y-axis guide rail 42, a sliding base 43, a lifting member 44 and a pneumatic shear 45. The Y-axis guide rail 42 is fixedly installed on the support frame 2 and is provided in parallel with two rows. The Y-axis guide rail 42 is arranged along the conveying direction of the conveying belt 3, and the two rows of Y-axis guide rails 42 are located on both sides of the conveying belt 3. The X-axis guide rail 41 is slidably connected to the two rows of Y-axis guide rails 42. The X-axis guide rail 41 moves along the length direction of the Y-axis guide rail 42. The linear movement of the X-axis guide rail 41 can be controlled by a pneumatic cylinder or a linear motor. The structure for controlling the linear movement belongs to a conventional means, which will not be described here.

[0040] The X-axis guide rail 41 is perpendicular to the Y-axis guide rail 42. The sliding base 43 is slidably connected to the X-axis guide rail 41 and moves horizontally along the length direction of the X-axis guide rail 41. The lifting member 44 is installed on the sliding base 43. The pneumatic shear 45 is connected to the lifting member 44 and is used for shearing the raw material. The lifting member 44 is used for controlling the pneumatic shear 45 to approach or move away from the conveying belt 3. The lifting member 44 is a linear cylinder, an oil cylinder or an electric push rod. In this embodiment, the linear cylinder is taken as an example. The pneumatic shear 45 is connected to the piston rod of the linear cylinder.

[0041] When the injection molded part is stably placed on the conveying belt 3, the lifting member 44 can be operated to control the pneumatic shear 45 to move downward in the vertical direction so as to approach the injection molded part. The pneumatic shear 45 can accurately determine the position of the raw material by means of a positioning sensor, and then perform a cutting operation to cut off the raw material.

[0042] Since the raw material on the surface of the injection molded part is not located at a single position, the sliding base 43 can move horizontally along the X-axis direction on the X-axis guide rail 41. At the same time, the entire X-axis guide rail 41 can move horizontally along the Y-axis direction on the Y-axis guide rail 42. Through this coordinated movement, the position of the pneumatic shear 45 relative to the injection molded part can be flexibly changed, so as to accurately cut the raw material at multiple positions on the surface of the injection molded part.

[0043] The support frame 2 is further provided with a positioning assembly 6. The positioning assembly 6 is used for positioning the injection molded part. The positioning assembly 6 comprises an ejection cylinder 61, a connecting frame 62, a compression roller 63 and a positioning roller 64. The ejection cylinder 61 is located on one side of the conveying belt 3. The connecting frame 62 is movably arranged above the conveying belt 3 and is connected to the piston rod of the ejection cylinder 61. The ejection cylinder 61 is used for controlling the movement of the connecting frame 62. The movement direction of the connecting frame 62 is parallel to the length direction of the X-axis guide rail 41.

[0044] The compression roller 63 is rotatably connected to the connecting frame 62, and the rotation axis of the compression roller 63 is perpendicular to the plane where the conveying belt 3 is located; the positioning roller 64 is located on the side of the conveying belt 3 away from the compression roller 63, and is also rotatable, the positioning roller 64 is parallel to the compression roller 63, and the compression roller 63 is used to compress the injection molded part on the positioning roller 64. The compression roller 63 is arranged at intervals along the conveying direction of the conveying belt 3, and the positioning roller 64 is also arranged at intervals along the conveying direction of the conveying belt 3.

[0045] When the injection molded part needs to be positioned, the ejection cylinder 61 is operated to control the entire connecting frame 62 to approach the injection molded part, so that the compression roller 63 abuts on the injection molded part and pushes the injection molded part to the positioning roller 64, and the positioning of the injection molded part is realized by the cooperation of the compression roller 63 and the positioning roller 64, and the stability of the position of the injection molded part is improved, so that the cutting work can be carried out. At the same time, when the cutting is finished and the conveying belt 3 needs to horizontally convey the injection molded part, since the compression roller 63 and the positioning roller 64 can rotate, the rolling friction with the injection molded part is realized, and the conveying belt 3 can convey the injection molded part without affecting the clamping and positioning of the injection molded part.

[0046] In combination Figure 4 In addition, in some embodiments, the blanking manipulator 5 is also provided with a fixing frame 7, and a plurality of suction accessories 8 are arranged on the fixing frame 7, and the suction accessories 8 are in the same plane. The suction accessories 8 use the principle of negative pressure adsorption to create a low-pressure area to adsorb the injection molded part on the surface of the raw material, and then the blanking manipulator 5 transfers the entire injection molded part to the stacking area for stacking. The plurality of suction accessories 8 can collectively adsorb on the injection molded part, increase the suction force on the injection molded part, and avoid the injection molded part from falling off the blanking manipulator 5 during the transfer process.

[0047] The implementation principle of the injection molded part raw material shearing device in the embodiment of the application is as follows: during production, first, the automatic material taking manipulator 1 provided with the injection molding machine is used to accurately take out the injection molded part after the injection molding process, and orderly place the injection molded part on the conveying belt 3. Then, the positioning assembly 6 on the support frame 2 is used to limit the position of the injection molded part; then the shearing assembly 4 is started, and the raw material on the surface of the injection molded part is sheared. After the rod-shaped raw material on the surface of the injection molded part is completely removed, the conveying belt 3 starts to run, and then drives the injection molded part to move forward by a certain distance. Finally, the blanking manipulator 5 takes the injection molded part from the conveying belt 3 and neatly stacks and stores the injection molded part in the designated storage area.

[0048] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
