Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a robotic arm for unloading injection molded parts. Background Technology

[0002] Injection molding part unloading robots use servo motors or cylinders to drive the robotic arm to precisely grasp molded parts and move them to the unloading station along a preset trajectory to complete sorting, stacking, or conveying. These robots are mainly used in automated production lines in the injection molding industry to replace manual labor in high-temperature, repetitive part-picking operations, improving production efficiency and reducing workplace injury risks. They are particularly widely used in intelligent factories that need to connect with subsequent assembly and packaging processes.

[0003] In injection molding, the structure of an injection-molded part typically comprises both the product body and the gating system. The gating connects the mold runner to the product body. During injection molding, molten plastic enters the mold runner through the injection molding machine nozzle and then fills the cavity through the gating. This process creates parts with specific functions, shapes, and dimensions according to design requirements.

[0004] In existing technologies, some injection molding part unloading robots typically grab the gate and the product together for unloading, making it difficult to unload the gate and the product separately. This leads to the need for manual separation of the gate and the product later, increasing labor input and time costs, and reducing the production efficiency of injection molding parts. Therefore, an injection molding part unloading robot is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a robotic arm for unloading injection molded parts, which aims to improve the problem in the prior art that the gate and the product are gripped together for unloading, making it difficult to unload the gate and the product separately.

[0009] The above technical solution involves a detachable connection between the top of the mounting plate and the cantilever, which, in conjunction with the mounting mechanism and clamping plate, ensures both stable connection and ease of disassembly and maintenance. The gripping mechanism at the bottom of the mounting plate can grip, clamp, and unload the injection molded product and the sprue. Horizontal arms are connected to both sides of the cantilever. Driven by a rotating motor, the turntable drives the cantilever and gripping mechanism to rotate laterally and longitudinally, precisely adjusting the gripping position. In the gripping mechanism, the drive motor drives the rotating rod to rotate, which, through the transmission rod and connecting plate, causes the moving plate to drive the clamping plate to hold the sprue. Simultaneously, the misalignment component within the gripping mechanism enables the misalignment and separation of the sprue and the injection molded product, ensuring a smooth unloading process.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the drive motor starts and drives the rotating rod to rotate. The rotation of the rotating rod drives the transmission rod to rotate, which moves the connecting plate, the moving plate, and the sliding plate, along with the two side clamps, towards the middle to hold the injection head. The suction cup picks up the injection molded product, thus achieving the clamping of the injection molded product along with the injection head. Then, the cylinder starts and drives the fixed plate to move down. The movement of the fixed plate then drives the air pipe to descend. The descent of the air pipe drives the suction cup to descend. At this time, the position between the injection head and the injection molded product is misaligned, causing them to separate. Then, the air pump stops, allowing the injection molded product to be discharged. The drive motor reverses and controls the rotating rod to rotate, causing the clamps to loosen, thus completing the misaligned discharge.

[0033] 2. In this utility model, rotating the fixing screws causes the mating plates to be unsecured. Therefore, rotating the rotating plate causes the mating plates to rotate. At this time, rotating the fixing screws inside the rotating plate also causes the rotating plate to be unsecured from the cantilever. Then, sliding the mounting plate allows the clamping plate to slide in the groove inside the cantilever, which facilitates the disassembly of the robot arm. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Specifically, after the rotating motor 7 fixed on the outer wall of the horizontal arm 12 is started, it can drive the turntable 10 and the cantilever 6 to rotate horizontally and vertically, which facilitates the gripping of materials. The gripping mechanism 2 uses the top plate 21 as a supporting component to install components such as the drive motor 23. The drive motor 23 on the top of the top plate 21 provides power for the gripping action. When the rotating rod 22 at its drive end rotates, it transmits power through the transmission rod 24 connected at both ends, which drives the connecting plate 25 connected at the other end to move, thereby causing the moving plate 26 fixed on the outer wall of the connecting plate 25 to move synchronously. The misalignment component 27 installed on the inner wall of the gripping mechanism 2 can separate the sprue 3 from the injection molded product 4 to realize the material unloading function.

A pouring head 3 is detachably connected to the inner side of the clamping plate 278 to facilitate clamping and fixing the pouring head 3 through the clamping plate 278.

[0046] Specifically, the misalignment component 27 includes a sliding plate 273, the top of which is slidably connected to the bottom of the top plate 21 and its position can be adjusted. A cylinder 272 is fixed at the bottom of the sliding plate 273, and the driving end of the cylinder 272 is connected to the fixed plate 271. After starting, the fixed plate 271 is moved up and down. A clamping plate 278 is fixed on the outer wall of the moving plate 26. When moving, the clamping plate 278 moves synchronously. The inner side of the clamping plate 278 is detachably connected to the pouring head 3, which is convenient for clamping and fixing the pouring head 3.

[0047] The bottom of the sprue 3 is detachably connected to the injection molded product 4. The connection between the sprue 3 and the injection molded product 4 requires a robotic arm for gripping and separating. An air pipe 274 is fixedly connected to the inner wall of the fixing plate 271. The air pipe 274 is used to connect to an external air pump to achieve the suction and release of the injection molded product 4. A suction cup 276 is fixedly connected to the bottom of the air pipe 274. The suction cup 276 is connected to the air pump through the air pipe 274 and is used to suction the injection molded product 4.

[0048] Specifically, the bottom of the sprue 3 is detachably connected to the injection molded product 4, which needs to be separated by a robotic arm. The air pipe 274 on the inner wall of the fixed plate 271 is connected to an external air pump. The bottom suction cup 276 is connected to the air pump through the air pipe 274, which adsorbs the top of the injection molded product 4 to achieve gripping. The material can be discharged when the air pump is turned off. The connecting rod 11 on the outer wall of the top plate 21 is connected to the crossbar 277. The crossbar 277 provides sliding support for the slide plate 275.

[0049] Reference Figures 1 to 3The mounting mechanism 5 includes multiple rotating plates 51, which are used to connect to the docking plate 53 and enable rotation. The outer walls of the multiple rotating plates 51 are rotatably connected to the outer wall of the mounting plate 1, allowing the rotating plates 51 to rotate relative to the mounting plate 1. The outer walls of the multiple rotating plates 51 are fixedly connected to the docking plates 53, which are used to connect to components such as the cantilever 6. The inner walls of the docking plates 53 are threaded with fixing screws 52, which can fix the docking plates 53 to the cantilever 6. The inner wall of the mounting plate 1 is fixedly connected with a clamping plate 55, which is used to engage with the sliding groove on the inner wall of the cantilever 6. The mounting plate 1 and the cantilever 6 are slidably connected by a 54-shaped joint. The outer wall of the clamping plate 55 is slidably connected to the inner wall of the cantilever 6, allowing the clamping plate 55 to slide on the inner wall of the cantilever 6, which facilitates the disassembly of the mounting plate 1. The inner wall of the cantilever 6 is provided with a groove 54 to provide a track for the sliding of the clamping plate 55. The inner wall of the turntable 10 is rotatably connected to a hydraulic rod 8, which is used to control the lifting and lowering of the cross arm 12 and the cantilever 6. The outer wall of the clamping plate 55 is slidably connected to the inner wall of the groove 54 to ensure the smooth sliding of the clamping plate 55. The top of the hydraulic rod 8 is fixedly connected to a fixing frame 9, which is used to install the hydraulic rod 8 and provide support.

[0050] Specifically, the installation mechanism 5 consists of multiple rotating plates 51. The outer wall of the rotating plate 51 is rotatably connected to the installation plate 1, and the end is fixed with a docking plate 53. The docking plate 53 is threadedly connected to the cantilever 6 by fixing screws 52 to fix the installation plate 1 and the cantilever 6. The clamping plate 55 on the inner wall of the installation plate 1 slides in conjunction with the slide groove 54 on the inner wall of the cantilever 6, which facilitates the sliding of the clamping plate 55 in the slide groove 54 during disassembly. The hydraulic rod 8 rotatably connected to the inner wall of the turntable 10 is fixed with a fixing bracket 9 at the top, which is used to control the lifting of the cross arm 12 and the cantilever 6. The sliding of the clamping plate 55 in the slide groove 54 ensures the smoothness of the installation plate 1 during disassembly or installation. The entire installation mechanism 5 realizes the flexible installation, fixing, disassembly and maintenance of the robot parts through the cooperation of the rotating plate 51, docking plate 53, fixing screws 52 and clamping plate 55 and slide groove 54.

[0051] Working principle: When the mechanical gripper is needed to grasp the injection molded product 4, the hydraulic rod 8 controls the horizontal arm 12 and the cantilever 6 to descend. Then, the turntable 10 and the rotating motor 7 control the cantilever 6 to drive the gripping mechanism 2 to rotate laterally and longitudinally to facilitate material gripping. At this time, the drive motor 23 starts and drives the rotating rod 22 to rotate. The rotation of the rotating rod 22 drives the transmission rod 24 to rotate, which drives the connecting plate 25, the moving plate 26, and the sliding plate 275, along with the two side clamping plates 278, to move towards the middle to clamp the injection head 3. Then, the external air pump connected to the air pipe 274 starts. The air pump uses air pipe 274 and suction cup 276 to pick up the injection molded product 4, thereby clamping the injection molded product 4 along with the sprue 3. Then, the cylinder 272 is activated, which drives the fixing plate 271 to move down. The movement of the fixing plate 271 causes the air pipe 274 to descend, and the descent of the air pipe 274 causes the suction cup 276 to descend. At this time, the position between the sprue 3 and the injection molded product 4 is misaligned, causing them to separate. Then, the air pump is turned off, allowing the injection molded product 4 to be unloaded. The drive motor 23 reverses the rotation of the rotating rod 22, causing the clamping plate 278 to be released, thus completing the misaligned unloading.

[0052] When the robotic arm needs to be disassembled for maintenance, the fixing screw 52 is rotated. The rotation of the fixing screw 52 leaves nothing to fix the docking plate 53. Therefore, the rotating plate 51 is rotated, causing the docking plate 53 to rotate. At this time, the fixing screw 52 inside the rotating plate 51 is also rotated, leaving nothing to fix the rotating plate 51 and the cantilever 6. Then, the mounting plate 1 is slid, allowing the clamping plate 55 to slide in the groove 54 inside the cantilever 6, which facilitates the disassembly of the robotic arm.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
