Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a post-injection molding processing device for automotive plastic parts. Background Technology

[0002] Post-injection molding processing equipment for automotive plastic parts refers to equipment or machines used for subsequent processing and treatment of automotive plastic parts after injection molding. For example, surface treatment equipment can be used for trimming and deburring, which can improve the appearance quality of the parts, increase their smoothness and aesthetics, and enhance the overall quality and visual effect of the car.

[0003] According to CN222270399U, a post-injection molding processing device for automotive plastic parts is disclosed. This technology discloses a "post-injection molding processing device for automotive plastic parts, including: a base plate and an operating table. A cylinder is fixedly connected to one end of the base plate, a support frame is fixedly connected to one end of the cylinder, an adjusting cabinet is fixedly connected to one side of the support frame, a motor is fixedly connected to one side of the adjusting cabinet, a lead screw is rotatably connected to one side of the adjusting cabinet, a slide plate is fixedly connected to the other side of the adjusting cabinet, a slider is slidably connected to the outside of the slide plate, and a movable base is fixedly connected to one end of the slider." The device has the technical effect of "the motor drives the lead screw to rotate, thereby driving the movable base to move the L-shaped cutter left and right, so that the outer and inner cutting edges of the L-shaped cutter can cut or trim the sides and top surfaces of multiple parts, ensuring that the surface of the parts is smooth and clean. The outer and inner cutting edges can effectively clean the surface of the parts when the L-shaped cutter moves, meeting the requirements of high-precision processing."

[0004] In the above scheme, the post-injection molding processing usually relies on manual handling and positioning of parts. This operation method is not only inefficient, but also causes fatigue for workers who engage in repetitive labor for a long time, which seriously restricts the overall efficiency of the production line. At the same time, due to individual differences in manual operation, it is difficult to guarantee the consistency of the position of parts when loading them, which often leads to a decrease in the accuracy of subsequent finishing processes such as deburring, and thus significantly increases the defect rate of products. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a post-injection molding processing device for automotive plastic parts, which enables automatic workpiece sorting, precise positioning, and continuous feeding, ensuring stable material supply, avoiding stacking chaos, and improving production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a post-injection molding processing device for automotive plastic parts, comprising a processing table and a workpiece, a disc mounted on the upper end of the processing table via a cam divider, and a processing mechanism provided on the processing table for processing the workpiece, the processing mechanism comprising:

[0007] The feeding assembly includes a base fixed to the top left of the processing table, a platform fixed to the top of the base, a limit frame fixed to the top right of the platform, a vertical plate fixed to the rear end of the platform, a hopper fixed to the front end of the vertical plate, a mounting base fixed to the rear end of the platform, a first finger cylinder mounted on the upper end of the mounting base, a clamping plate fixed to both claws of the first finger cylinder, a second finger cylinder fixed to the rear end of the vertical plate, a support plate fixed to both claws of the second finger cylinder, a dual-axis cylinder fixed to the front end of the base, a connector fixed to the output end of the dual-axis cylinder, and a push plate fixed to the upper end of the connector.

[0008] A pick-and-place assembly is set on the processing table and used for picking up and placing discs.

[0009] A positioning component is mounted on the disk and used to position the disk.

[0010] Preferably, the feeding assembly further includes a guide seat fixed to the rear end of the base, and a guide rod is slidably installed inside the guide seat and fixed to the connector.

[0011] Preferably, the pick-and-place assembly further includes a stand fixed to the rear of the top of the processing table, a slide plate slidably mounted on the stand, a first cylinder fixed to the right end of the stand for driving the slide plate, a slider slidably mounted on the slide plate, a second cylinder fixed to the upper end of the slide plate for driving the slider, and a third finger cylinder fixed on the slider.

[0012] Preferably, the positioning component includes a plurality of positioning fixtures fixedly distributed around the outer edge of the top of the disk, the top of the positioning fixtures having a positioning groove, and a positioning head fixed inside the positioning groove.

[0015] Beneficial effects

[0016] This invention provides a post-injection molding processing device for automotive plastic parts. Compared with the prior art, it has the following advantages:

[0017] 1. By stacking multiple workpieces inside the hopper, the first finger cylinder drives the pallet to open, allowing the stacked workpieces to fall onto the pallet. Then, the first finger cylinder drives the pallet to close, inserting it above the bottom workpiece, thus separating the bottom workpiece from the rest of the stacked workpieces above it. The rest of the stacked workpieces above are temporarily supported by the pallet. The second finger cylinder then drives the pallet to open, allowing the previously separated bottom workpiece to fall onto the top of the platform. The output end of the dual-axis cylinder drives the connector to move the push plate to the right, pushing the workpiece on the top of the platform into the limit frame, facilitating subsequent grabbing by the pick-and-place component. Repeating the above steps ensures that workpieces are fed one by one, preventing stacked workpieces from becoming disordered and improving feeding stability.

[0018] 2. When the dual-axis cylinder drives the connecting part to move, the connecting part drives the guide rod to slide along the guide seat, which improves the stability during the movement, prevents the workpiece from deviating during the pushing process, and improves the feeding accuracy; when the third finger cylinder grabs and places the workpiece, it avoids interference with it through the slot hole, ensuring smooth operation and improving the reliability of the system.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Please see Figure 1 - Figure 7 This utility model provides a technical solution: a post-injection molding processing device for automotive plastic parts, including a processing table 1 and a workpiece 4. A disc 3 is mounted on the upper end of the processing table 1 via a cam divider. A processing mechanism 2 is provided on the processing table 1 for processing the workpiece 4. The processing mechanism 2 includes:

[0029] The feeding assembly 21 includes a base 211 fixed to the top left side of the processing table 1, a platform 212 fixed to the top of the base 211, a limit frame 213 fixed to the top right end of the platform 212, a vertical plate 214 fixed to the top rear end of the platform 212, a hopper 215 fixed to the front end of the vertical plate 214, a mounting base 216 fixed to the rear end of the platform 212, a first finger cylinder 217 mounted on the upper end of the mounting base 216, two claws of the first finger cylinder 217 fixed with clamping plates 218, a second finger cylinder 219 fixed to the rear end of the vertical plate 214, two claws of the second finger cylinder 219 fixed with support plates 2110, a dual-axis cylinder 2111 fixed to the front end of the base 211, a connector 2112 fixed to the output end of the dual-axis cylinder 2111, and a push plate 2113 fixed to the upper end of the connector 2112.

[0030] The pick-and-place assembly 22 is set on the processing table 1 and is used to pick up and place the disc 3.

[0031] Positioning component 23 is disposed on disk 3 and used to position disk 3.

[0032] In this embodiment, multiple workpieces 4 are stacked inside the hopper 215. The first finger cylinder 217 drives the clamping plate 218 to open, allowing the stacked workpieces 4 to fall onto the pallet 2110. The first finger cylinder 217 then drives the clamping plate 218 to close, inserting it above the bottommost workpiece 4, thus separating the bottommost workpiece 4 from the remaining stacked workpieces 4 above. The remaining stacked workpieces 4 above are temporarily supported by the clamping plate 218. The second finger cylinder 219 then drives the pallet 2110 to open, allowing the previously separated bottommost workpiece 4 to fall onto the top of the platform 212. The output end of the dual-axis cylinder 2111 drives the connector 2112 to move the push plate 2113 to the right, causing the push plate 2113 to push the workpiece 4 on the top of the platform 212 into the limiting frame 213, facilitating subsequent grabbing by the pick-and-place component 22. The above steps are repeated to ensure that the workpieces 4 are fed one by one, preventing stacked workpieces from becoming disordered and improving feeding stability.

[0033] Specifically, the feeding assembly 21 also includes a guide seat 2114 fixed to the rear end of the base 211. A guide rod 2115 is slidably installed inside the guide seat 2114 and fixed to the connector 2112.

[0034] In this embodiment, when the dual-axis cylinder 2111 drives the connecting member 2112 to move, the connecting member 2112 drives the guide rod 2115 to slide along the guide seat 2114, which improves the stability during the movement, prevents the workpiece from deviating during the pushing process, and improves the feeding accuracy.

[0035] Specifically, the pick-and-place assembly 22 also includes a stand 221 fixed to the rear of the top of the processing table 1. A slide plate 222 is slidably mounted on the stand 221. A first cylinder 223 is fixed to the right end of the stand 221 and is used to drive the slide plate 222. A slider 224 is slidably mounted on the slide plate 222. A second cylinder 225 is fixed to the upper end of the slide plate 222 and is used to drive the slider 224. A third finger cylinder 226 is fixed on the slider 224.

[0036] In this embodiment, the workpiece 4 is gripped by the third finger cylinder 226, the slider 224 is driven by the second cylinder 225 to move the third finger cylinder 226 up and down, and the slide plate 222 is driven by the first cylinder 223 to move laterally, so as to automatically grip the workpiece 4 on the feeding component 21 and place it on the positioning component 23, thereby completing the automatic handling of the workpiece, reducing manual operation and improving positioning consistency.

[0037] Specifically, the positioning component 23 includes several positioning fixtures 231 that are fixedly distributed around the outer edge of the top of the disk 3. The top of the positioning fixture 231 is provided with a positioning groove 232, and a positioning head 233 is fixed inside the positioning groove 232.

[0038] In this embodiment, after the workpiece 4 is placed inside the positioning groove 232 of the positioning fixture 231, it is positioned by the positioning head 233 to avoid shaking during processing and improve the accuracy of post-processing such as deburring.

[0039] Specifically, the processing mechanism 2 also includes a processing component 24 for deburring the disc 3, including a three-axis module 241 fixed on the top right side of the processing table 1, a motor 242 mounted on the three-axis module 241, and a grinding head 243 fixed to the output end of the motor 242.

[0040] In this embodiment, the three-axis module 241 on the motor 242 is controlled by the three-axis module 241 to move directly above the workpiece 4, and the grinding head 243 is driven by the motor 242 to grind the workpiece 4.

[0041] Specifically, the processing mechanism 2 also includes slots 25 opened inside the limit frame 213, at the right end of the push plate 2113, and at both ends of the positioning groove 232.

[0042] In this embodiment, when the third finger cylinder 226 grips and places the workpiece 4, it avoids interference with it through the slot 25, ensuring smooth operation and improving system reliability.

[0043] The working principle and usage process of this utility model are as follows: First, multiple workpieces 4 are stacked inside the hopper 215. The first finger cylinder 217 drives the clamping plate 218 to open, causing the stacked workpieces 4 to fall onto the tray 2110. Then, the first finger cylinder 217 drives the clamping plate 218 to close, causing the clamping plate 218 to insert above the bottommost workpiece 4, thereby separating the bottommost workpiece 4 from the remaining stacked workpieces 4 above. The remaining stacked workpieces 4 above are temporarily supported by the clamping plate 218. Then, the second finger cylinder 219 drives the tray 2110 to open, so that the workpiece 4 that was previously separated at the bottom falls into the top of the platform 212. Then, the output end of the dual-axis cylinder 2111 drives the connector 2112 to move the push plate 2113 to the right, so that the push plate 2113 pushes the workpiece 4 at the top of the platform 212 into the limit frame 213, so that the subsequent pick-and-place component 22 can grab it. Repeat the above steps to ensure that the workpiece 4 is fed one by one, prevent the stacked workpieces from being messy, and improve the stability of the feeding.

[0044] Then, the pick-and-place component 22 picks up the workpiece 4 from the top of 212 and places it on the positioning component 23. After the workpiece 4 is placed inside the positioning groove 232 of the positioning fixture 231, it is positioned by the positioning head 233 to avoid shaking during processing and improve the accuracy of post-processing such as deburring.

[0045] Finally, the cam divider controls the rotation of the disc 3, which in turn moves the workpiece 4 on the positioning component 23 to one side of the processing component 24. Then, the three-axis module 241 on the motor 242 is controlled by the three-axis module 241 to move directly above the workpiece 4, and the grinding head 243 is driven by the motor 242 to grind the workpiece 4.
