Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding technology, and in particular to a material handling gripper for injection molded parts. Background Technology
[0002] Injection molding is a method of shaping industrial products. Due to its high efficiency and precision, injection molding is widely used in various fields, such as injection-molded parts for automotive oil cans, printers, medical devices, and battery covers. Injection molding is typically achieved using an injection molding machine, which is the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding is achieved through the injection molding machine and the mold. After injection molding, the molded product and any waste material need to be removed from the mold using a material handling gripper. The material handling gripper is usually connected to a robotic arm, which drives its movement.
[0003] Currently, traditional material handling grippers have significant limitations: their material handling clamps or suction cups are usually designed to be fixed. In actual production, when it is necessary to change the mold to produce products of different specifications or shapes, the operator needs to change the material handling grippers that match the product shape, which requires the preparation of many sets of material handling clamps and increases production costs. Utility Model Content
[0004] To solve the above problems, this utility model provides a material handling gripper for injection molded parts.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a material handling gripper for injection molding parts, comprising a fixed plate connected to a robotic arm, a mounting block provided on the fixed plate, a mounting groove provided on the side of the mounting block away from the fixed plate, two sliders slidably disposed in the mounting groove, a driving component provided on the mounting block for driving the two sliders to slide synchronously in opposite directions, a moving plate provided on the side of the sliders away from the connecting plate, a first mounting plate provided on each of the two moving plates away from each other, a second mounting plate slidably disposed on the moving plate, a fixing component provided on the second mounting plate for fixing the second mounting plate to the moving plate, two connecting plates slidably disposed on both the first and second mounting plates, a waste suction cup provided on the connecting plate on the first mounting plate, and a material handling suction cup provided on the connecting plate on the second mounting plate.
[0006] By adopting the above technical solution, a fixed plate, mounting block, drive assembly, connecting plate, first mounting plate, second mounting plate, waste suction cup, and material retrieval suction cup are set up. The robotic arm drives the fixed plate, mounting block, waste suction cup, and material retrieval suction cup to move, simultaneously gripping the injection molded product and injection waste material inside the injection mold. The drive assembly drives two sliders to slide synchronously in opposite directions, moving the two connecting plates, the first mounting plate, and the second mounting plate, thereby moving the waste suction cup and material retrieval suction cup. The sliding of the second mounting plate moves the material retrieval suction cup, changing the distance between the material retrieval suction cup and the waste suction cup. The connecting plate slides on the first or second mounting plate, moving the waste suction cup or material retrieval suction cup. This allows the positions of the waste suction cup and material retrieval suction cup to be adjusted, enabling a single gripper for picking up injection molded parts to adapt to products of different specifications or shapes, reducing production costs.
[0007] Furthermore, the waste suction cup is connected to a waste air pipe, and several waste air pipes are connected through a first air pipe, which is connected to an external air source. The material suction cup is connected to a material retrieval air pipe, and several material retrieval air pipes are connected through a second air pipe, which is connected to another external air source.
[0008] By adopting the above technical solution, a waste gas pipe, a first gas pipe, a material picking gas pipe, and a second gas pipe are set up so that the four material picking suction cups and the four waste suction cups are driven by two external air sources respectively, so that the injection molded products and injection molded waste can be placed separately.
[0009] Furthermore, both the first and second mounting plates have two symmetrically arranged strip-shaped holes. A sliding block is slidably arranged in the strip-shaped hole. A threaded hole and a guide hole are spaced apart on the sliding block. A threaded rod is spirally arranged in the threaded hole, and a guide rod is slidably arranged in the guide hole. A U-shaped seat is provided at one end of the threaded rod and the guide rod. One end of the threaded rod is rotatably connected to the U-shaped seat, and the other end is provided with a control handle. The connecting plate is connected to the corresponding U-shaped seat.
[0010] By adopting the above technical solution, a strip hole, a sliding block, a threaded rod, and a U-shaped seat are set. Rotating the control handle drives the threaded rod to rotate, thereby changing the distance between the U-shaped seat and the sliding block, and thus changing the distance between the waste suction cup, the material suction cup, and the sliding block. This allows the front and rear positions of the waste suction cup and the material suction cup to be adjusted according to the shape of the injection molded product or the injection waste.
[0011] Furthermore, the sliding block is provided with sliding grooves on both sides, the bottom of the sliding groove is slidably connected to the wall of the strip hole, and the wall of the sliding groove is slidably connected to the surface of the first mounting plate or the second mounting plate.
[0012] By adopting the above technical solution, grooves are set on both sides of the sliding block to ensure the stability of the sliding block.
[0013] Furthermore, a connecting seat is provided on one side of the sliding block, and a bolt is screwed onto the connecting seat through a screw hole.
[0014] By adopting the above technical solution, a connecting seat and bolts are set. When the bolt ends abut against the first mounting plate or the second mounting plate, the position of the sliding block is fixed.
[0015] Furthermore, the drive assembly includes a bidirectional threaded rod rotatably disposed in the mounting groove, and the two sliders are respectively threaded to both ends of the bidirectional threaded rod through threaded holes. One end of the bidirectional threaded rod passes through the mounting block and is provided with a rotating handle.
[0016] By adopting the above technical solution, a bidirectional threaded rod and a rotating handle are set up. Rotating the rotating handle drives the bidirectional threaded rod to rotate. Since the two sliders are respectively threaded to both ends of the bidirectional threaded rod through threaded holes, the two sliders slide synchronously in opposite directions when the bidirectional threaded rod rotates.
[0017] Furthermore, the movable plate has an oblong hole, the length direction of which is consistent with the length direction of the movable plate. The fixing component includes a screw rod disposed in the middle of the second mounting plate, the screw rod passing through the oblong hole and having a nut screwed on it.
[0018] By adopting the above technical solution, a waist-shaped hole, a screw rod, and a nut are provided. When the second mounting plate moves, the screw rod slides in the waist-shaped hole, and the nut is rotated. When one side of the nut contacts the surface of the moving plate, the nut is tightened, thereby fixing the position of the screw rod and the second mounting plate.
[0019] In summary, this utility model has the following beneficial effects: This application includes a fixed plate, mounting block, drive assembly, connecting plate, first mounting plate, second mounting plate, waste suction cup, and material retrieval suction cup. The robotic arm moves the fixed plate, mounting block, waste suction cup, and material retrieval suction cup to simultaneously grip the injection molded product and injection waste within the injection mold. The drive assembly drives two sliders to slide synchronously in opposite directions, moving the two connecting plates, the first mounting plate, and the second mounting plate, thereby moving the waste suction cup and material retrieval suction cup. The sliding of the second mounting plate moves the material retrieval suction cup, changing the distance between the material retrieval suction cup and the waste suction cup. The connecting plate slides on the first or second mounting plate, moving the waste suction cup or material retrieval suction cup. This allows the positions of the waste suction cup and material retrieval suction cup to be adjusted, enabling a single gripper for picking up injection molded parts to adapt to products of different specifications or shapes, reducing production costs.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0025] like Figure 1-3As shown in the embodiment of this application, a material handling gripper for injection molded parts is disclosed, including a fixed plate 10, a mounting block 11, a drive assembly 20, a connecting plate 32, a waste suction cup 33, and a material handling suction cup 34. The fixed plate 10 is connected to a robotic arm. The mounting block 11 is generally cuboid and is mounted on the fixed plate 10. A mounting groove 12 is formed on the side of the mounting block 11 away from the fixed plate 10. The length direction of the mounting groove 12 is consistent with the length direction of the mounting block 11. Two sliders 13 are slidably disposed in the mounting groove 12. The drive assembly 20 is provided on the mounting block 11 to drive the two sliders 13 to slide synchronously in opposite directions. A movable plate 14 is provided on the side of the slider 13 away from the connecting plate 32. The length direction of the movable plate 14 is consistent with the length direction of the mounting block 11. A first mounting plate 30 is provided on each side of the two movable plates 14 away from each other. A second mounting plate 31 is slidably disposed on the movable plate 14. The length directions of the first mounting plate 30 and the second mounting plate 31 are both perpendicular to the length direction of the mounting block 11. The second mounting plate 31 is provided with a fixing component 40 for fixing the second mounting plate 31 to the movable plate 14. Two connecting plates 32 are slidably mounted on both the first mounting plate 30 and the second mounting plate 31. There are four waste suction cups 33, which are respectively mounted on the four connecting plates 32 on the two first mounting plates 30. There are four material retrieval suction cups 34, which are respectively mounted on the four connecting plates 32 on the two second mounting plates 31.
[0026] The robotic arm moves the fixed plate 10, mounting block 11, waste suction cup 33, and material handling suction cup 34 to simultaneously grip the injection molded product and injection waste within the injection mold. The drive assembly 20 drives two sliders 13 to slide synchronously in opposite directions, moving the two connecting plates 32, the first mounting plate 30, and the second mounting plate 31, thereby moving the waste suction cup 33 and the material handling suction cup 34 for adjustment in the left-right direction. The sliding of the second mounting plate 31 moves the material handling suction cup 34, changing the distance between it and the waste suction cup 33, adjusting according to the specific positions of the injection molded product and injection waste. The connecting plate 32 slides on the first mounting plate 30 or the second mounting plate 31, moving the waste suction cup 33 or the material handling suction cup 34 for adjustment in the up-down direction. This allows the positions of the waste suction cup 33 and the material handling suction cup 34 to be adjusted, enabling a single gripper for handling injection molded parts to adapt to products of different specifications or shapes, reducing production costs.
[0027] Specifically, the waste suction cup 33 is connected to a waste air pipe 35, and several waste air pipes 35 are connected through a first air pipe, which is connected to an external air source. The material suction cup 34 is connected to a material picking air pipe 36, and several material picking air pipes 36 are connected through a second air pipe, which is connected to another external air source. This allows the four material picking suction cups 34 and the four waste suction cups 33 to be driven by two external air sources respectively, enabling the injection molded product and the injection molded waste to be placed separately. The external air source can be an air pump.
[0028] During setup, two strip-shaped holes 37 are symmetrically opened on both the first mounting plate 30 and the second mounting plate 31. The length direction of the strip-shaped holes 37 is perpendicular to the length direction of the first mounting plate 30. A sliding block 50 is slidably arranged in the strip-shaped holes 37. A threaded hole and a guide hole are spaced apart on the sliding block 50. A threaded rod 51 is spirally arranged in the threaded hole, and a guide rod 52 is slidably arranged in the guide hole. A U-shaped seat 53 is provided at one end of the threaded rod 51 and the guide rod 52. One end of the threaded rod 51 is rotatably connected to the U-shaped seat 53, and the other end is provided with a control handle 54. The connecting plate 32 is connected to the corresponding U-shaped seat 53. Rotating the control handle 54 drives the threaded rod 51 to rotate, thereby changing the distance between the U-shaped seat 53 and the sliding block 50, and thus changing the distance between the waste suction cup 33, the material picking suction cup 34 and the sliding block 50. This allows the front and rear positions of the waste suction cup 33 and the material picking suction cup 34 to be adjusted according to the shape of the injection molded product or the injection molded waste. The sliding block 50 has grooves 55 on both sides. The bottom of the groove 55 is slidably connected to the wall of the slot 37, and the wall of the groove 55 is slidably connected to the surface of the first mounting plate 30 or the second mounting plate 31, ensuring the stability of the sliding block 50. A connecting seat 56 is provided on one side of the sliding block 50. A bolt 57 is screwed onto the connecting seat 56 through a screw hole. When the bolt 57 is rotated, and its end abuts against the first mounting plate 30 or the second mounting plate 31, the position of the sliding block 50 is fixed. When the bolt 57 is separated from the first mounting plate 30 or the second mounting plate 31, the sliding block 50 can slide.
[0029] In a specific configuration, the drive assembly 20 includes a bidirectional threaded rod 21 and a rotating handle 22. The bidirectional threaded rod 21 is rotatably mounted in the mounting groove 12, and the length direction of the bidirectional threaded rod 21 is consistent with the length direction of the mounting groove 12. Two sliders 13 are respectively threaded to both ends of the bidirectional threaded rod 21 through threaded holes. One end of the bidirectional threaded rod 21 passes through the mounting block 11, and the rotating handle 22 is located at the end of the bidirectional threaded rod 21 that passes through the mounting block 11. Rotating the rotating handle 22 drives the bidirectional threaded rod 21 to rotate, so that the two sliders 13 slide synchronously in opposite directions.
[0030] The movable plate 14 has an oblong hole 41, the length of which is consistent with the length of the movable plate 14. The fixing component 40 includes a screw rod 42 disposed in the middle of the second mounting plate 31. The screw rod 42 passes through the oblong hole 41 and is screwed with a nut 43. When the second mounting plate 31 moves, the screw rod 42 slides in the oblong hole 41 and rotates the nut 43. When one side of the nut 43 contacts the surface of the movable plate 14, the nut 43 is tightened, thereby fixing the position of the screw rod 42 and the second mounting plate 31.
[0031] The working principle of the injection molding part picking gripper in this embodiment is as follows:
[0032] The robotic arm moves the fixed plate 10, mounting block 11, waste suction cup 33, and material retrieval suction cup 34 to simultaneously grab the injection molded product and injection waste inside the injection mold. The four material retrieval suction cups 34 and the four waste suction cups 33 are driven by two external air sources to separate the injection molded product and injection waste.
[0033] When changing injection molds to produce another product model, first rotate the handle 22 to rotate the bidirectional threaded rod 21, causing the two sliders 13 to slide synchronously in opposite directions, moving the two connecting plates 32, the first mounting plate 30, and the second mounting plate 31. This moves the waste suction cup 33 and the material suction cup 34 to adjust their left and right positions. Then, slide the second mounting plate 31 to move the material suction cup 34, changing the distance between the material suction cup 34 and the waste suction cup 33. Finally, tighten the nut 43 to fix the position of the second mounting plate 31. Next, slide the slider 13 to move the guide rod 52, the threaded rod 51, and the connecting plate 32, moving either the waste suction cup 33 or the material suction cup 34 to adjust their up and down positions. Finally, tighten the bolt 57 to fix the position of the sliding block 50. Then, rotating the control handle 54 drives the threaded rod 51 to rotate, thereby changing the distance between the U-shaped seat 53 and the sliding block 50, and thus changing the distance between the waste suction cup 33 or the material suction cup 34 and the sliding block 50. This adjusts the front and rear positions of the waste suction cup 33 and the material suction cup 34, so that one injection molding part picking gripper can adapt to products of different specifications or shapes, reducing production costs.
[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
