Description

Technical Field

[0001] This invention relates to the field of assembly robot technology, and more particularly to an assembly robot for injection mold inserts. Background Technology

[0002] The injection mold insert assembly robot is a specialized automated device used in the injection molding process of inserts. Its core function is to replace manual labor by feeding various inserts such as nuts, copper sleeves, and metal terminals into the injection mold cavity for positioning. After the mold is closed and injection molding is completed, the finished part with the insert is removed from the mold. This realizes full automation of insert loading, in-mold assembly, and product removal. It mainly solves problems such as low efficiency, poor positioning accuracy, easy mold damage, unstable product yield, and safety operation risks associated with manual insert placement.

[0003] Traditional injection mold insert assembly robots lack corresponding correction and centering positioning mechanisms when assembling inserts. During the process of gripping and transferring inserts, unstable clamping, transfer vibration, or gaps between the mechanical gripper and the insert often cause one end of the insert to tilt and lift up. After the insert tilts or shifts, it is directly inserted into the mold, which can easily lead to misalignment between the insert and the cavity, and squeezing and collision during mold closing.

[0004] Therefore, it is necessary to provide a robot for assembling injection mold inserts to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with related technologies, the injection mold insert assembly robot provided by the present invention has the following advantages: This invention provides a robotic arm for assembling injection mold inserts.

A first hydraulic cylinder pushes the connecting plate and the movable plate downwards, cooperating with the guide rod and the inclined groove of the side plate to guide the alignment plate to adapt to the insert's posture, achieving flexible correction. The push rod, contact rod, and second spring form an elastic pressing structure, which, with the cooperation of the pressure plate, smoothly presses the warped insert, effectively preventing rigid extrusion from causing deformation or scratches. The second inclined surface at the bottom of the push rod cooperates with the first inclined surface in the groove of the L-shaped sliding seat, which can simultaneously push the positioning rods on both sides to extend towards each other, accurately guiding the offset insert to the predetermined position above the mold, achieving automatic centering and positioning without manual intervention, and is suitable for continuous production. By coordinating the cleaning and dust removal mechanisms and internal components, the system can remove statically adsorbed dust and debris from the surface of the insert before it enters the mold, preventing impurities from entering the cavity and causing product defects. This significantly improves the appearance quality and yield of the injection-molded product. The first motor drives multiple rotating cylinders and impurity removal brushes to rotate synchronously via sprockets and chains, physically cleaning the surface of the insert. Combined with a dust collection device, dust collection pipe, and filter, impurities are promptly removed to prevent secondary dust pollution. The air pump and high-pressure ion generator deliver high-pressure airflow and positive and negative ions to the three-way pipe through the first and second multi-head pipes, respectively. The resulting ion wind is ejected from the nozzle, quickly neutralizing the static electricity of the insert and removing residual dust. The second motor drives the cam to rotate, which, in conjunction with rack and pinion transmission, drives two strip rods to slide synchronously in opposite directions. Through the telescopic rod, the nozzle swings back and forth, achieving multi-angle full-coverage cleaning without dead corners. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] First embodiment: Please refer to the following: Figures 1-9 In the first embodiment of the present invention, the injection mold insert assembly robot includes: a gantry robot 2 fixedly installed on the top of the injection molding machine 1. The gantry robot 2 adopts the gantry robot in the prior art injection mold insert assembly robot, which includes: a gantry frame, a multi-axis motion mechanism, a lifting arm and an electric hoist, etc. The bottom end of the lifting arm of the gantry robot 2 is fixedly installed with a fixed mounting base. The fixed mounting base is provided with a leveling device. The leveling device includes a pressing component and a centering component. Both the pressing component and the centering component are provided on the lifting arm. The pressing component is used to press the insert with one end tilted and raised, and the centering component is used to guide the insert to a predetermined position directly above the mold.

[0021] The pressing assembly includes a lifting seat 3, a connecting plate 11, a movable plate 7, a leveling plate 9, and two push rods 10. The lifting seat 3 is located on one side of the fixed mounting base. A gripper mechanism 8 is fixedly installed on the lifting seat 3. A second hydraulic cylinder 6 is fixedly installed on the side of the fixed mounting base away from the lifting seat 3. The telescopic end of the second hydraulic cylinder 6 passes through the fixed mounting base and is fixedly connected to the lifting seat 3. The connecting plate 11 is slidably installed on the inner wall of one side of the lifting seat 3. A first hydraulic cylinder 4 is fixedly installed on the top of the lifting seat 3. The telescopic end of the first hydraulic cylinder 4 extends into the lifting seat 3 and is fixedly connected to the connecting plate 11. The movable plate 7 is slidably installed on the bottom of the connecting plate 11. One end of a guide rod 12 is fixedly installed on both outer walls of the movable plate 7. Two side guide rods 10 are fixedly installed inside the lifting seat 3. The movable plate 7 has inclined grooves on both side plates. The other ends of the two guide rods 12 extend into the two inclined grooves respectively, and the two guide rods 12 are slidably connected to the two inclined grooves respectively. A sliding block 16 is slidably installed on one side outer wall of the movable plate 7. The aligning plate 9 is rotatably installed on the side away from the movable plate 7 from the sliding block 16. A support plate is fixedly installed on one side outer wall of the movable plate 7. Two top rods 10 are slidably installed through and on the support plate. The outer walls of the two top rods 10 are integrally formed with limiting flanges. A first spring 15 is sleeved on the outer side of the two top rods 10. The two ends of the first spring 15 are fixedly connected to the limiting flange and the support plate respectively. A contact rod 14 is slidably installed inside the two top rods 10. The top end of the contact rod 14 extends outside the top rod 10. One end of the second spring 17 is fixedly installed, and the other end of the second spring 17 is fixedly connected to the bottom end of the contact rod 14. The push rod 10, the contact rod 14, and the second spring 17 form an elastic pressing structure. A pressure plate 5 is installed on the upper mold of the injection molding machine 1. With the cooperation of the pressure plate 5, the raised insert is smoothly pressed and straightened, effectively preventing deformation or scratches caused by rigid extrusion. When one end of the insert tilts and tilts, the first hydraulic cylinder 4 is activated. The telescopic end of the first hydraulic cylinder 4 pushes the connecting plate 11 to slide downward along the inner wall of the lifting seat 3. The connecting plate 11 drives the movable plate 7 to move downward. The movable plate 7 slides along the inclined groove of the side plate of the lifting seat 3 through the guide rods 12 on both sides, and moves towards the insert while driving the movable plate 7 to descend. At this time, the bottom of the straightening plate 9 is in contact with the top of the tilted insert, and the machine closes. When the first hydraulic cylinder 4 is closed, and the insert causes one side of the sizing plate 9 to tilt, the tilted side first contacts the bottom end of one of the ejector rods 10, raising it slightly. Then, the injection molding machine 1 is started, causing the upper mold to descend. The upper mold then causes the pressure plate 5 to descend synchronously. At this time, the pressure plate 5 contacts the top of the higher contact rod 14, pressing the contact rod 14 down and compressing the second spring 17. The compression of the second spring 17 acts as a buffer, preventing rigid compression from damaging the insert. Subsequently, the contact rod 14 causes the ejector rod 10 to descend, continuously applying pressure to the tilted side of the sizing plate 9. The sizing plate 9 continues to press down on the tilted insert, correcting it until the insert is completely level. This allows for automatic correction of tilting, tilting, and eccentricity issues before the insert enters the mold.To prevent misalignment of the inserts, damage to the mold, and injection molding defects, the first hydraulic cylinder 4 pushes the connecting plate 11 and the movable plate 7 downwards. This, combined with the guiding movement of the guide rod 12 and the inclined groove of the side plate, allows the aligning plate 9 to adaptively conform to the insert's posture, achieving flexible correction.

[0022] The centering component includes a stop rod 13, two L-shaped sliding seats 20, and multiple positioning rods 21. The stop rod 13 is fixedly installed at the bottom of the balancing plate 9, and the bottom of the stop rod 13 has a second inclined surface. Each of the two gripper mechanisms 8 has a sliding chamber. The two L-shaped sliding seats 20 are slidably installed in the two sliding chambers respectively. One end of each of the multiple positioning rods 21 is fixedly installed on the side of the two L-shaped sliding seats 20 that is close to each other, and the other end of each of the multiple positioning rods 21 extends outside the two gripper mechanisms 8. One end of each of the multiple third springs 19 is fixedly installed on the side of the two L-shaped sliding seats 20 that is close to each other, and the other end of each of the multiple third springs 19 is fixedly connected to the two sliding chambers respectively. The top of each of the two L-shaped sliding seats 20 has a groove 18. The bottom of the groove 18 is provided with a first inclined surface. The second inclined surface at the bottom of the abutment rod 13 cooperates with the first inclined surface of the groove 18, which can simultaneously push the positioning rods 21 on both sides to extend towards each other, accurately guiding the offset insert to the predetermined position above the mold, and achieving automatic centering positioning. While the insert is horizontally aligned, the abutment rod 13 at the bottom of the aligning plate 9 descends. The second inclined surface at the bottom of the abutment rod 13 inserts into the first inclined surface of the groove 18 at the top of the L-shaped sliding seat 20. Through the inclined plane transmission, the two L-shaped sliding seats 20 are pushed to slide towards the insert. The L-shaped sliding seats 20 compress the third spring 19, causing the positioning rod 21 to extend out from the gripper mechanism 8 and push the insert from both sides simultaneously, guiding the offset insert to the predetermined position above the mold, and completing the precise centering positioning.

[0023] In this embodiment: First, the gantry-type robotic arm 2 is activated. The gantry-type robotic arm 2 drives the fixed mounting base downwards, and the gripper mechanism 8 closes to complete the insertion gripping. After gripping, the robotic arm rises slightly, moving above the injection mold assembly position, and then sends the insertion into the mold. When one end of the insertion tilts and lifts up, the first hydraulic cylinder 4 is activated. The telescopic end of the first hydraulic cylinder 4 pushes the connecting plate 11 to slide downwards along the inner wall of the lifting seat 3. The connecting plate 11 drives the movable plate 7 to move downwards. The movable plate 7 slides along the inclined groove of the side plate of the lifting seat 3 via the guide rods 12 on both sides, moving towards the insertion while descending. At this time, the bottom of the aligning plate 9 is in contact with the top of the tilted insertion, and the first hydraulic cylinder 4 is closed. When the insert causes one side of the aligning plate 9 to tilt, the tilted side first contacts the bottom end of one of the push rods 10 and lifts it up a little. Then the injection molding machine 1 is started, and the injection molding machine 1 drives the upper mold to descend. The upper mold drives the pressure plate 5 to descend synchronously. At this time, the pressure plate 5 contacts the top of the higher contact rod 14 and presses the contact rod 14 down, compressing the second spring 17. The second spring 17 is compressed and plays a buffering role to avoid rigid extrusion damage to the insert. Then the contact rod 14 drives the push rod 10 to descend and continues to apply pressure to the tilted side of the aligning plate 9. The aligning plate 9 continues to press down on the tilted insert and press it to correct it until the insert is completely horizontal and aligned. While the insert is horizontally aligned, the abutment 13 at the bottom of the aligning plate 9 descends. The second inclined surface at the bottom of the abutment 13 inserts into the first inclined surface of the groove 18 at the top of the L-shaped sliding seat 20. Through the inclined surface transmission, the two L-shaped sliding seats 20 are pushed to slide towards the insert. The L-shaped sliding seats 20 compress the third spring 19, causing the positioning rod 21 to extend out from the gripper mechanism 8 and push the insert from both sides simultaneously, guiding the offset insert to the predetermined position above the mold, thus completing the precise centering positioning. Finally, the gantry robot 2 drives the gripper mechanism 8 to move down and assemble the insert into the preset station of the injection mold. After the assembly is completed, the gripper mechanism 8 opens and the robot resets, completing a single insert assembly operation.

[0024] Second embodiment: The second embodiment of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 10-17 In the injection mold insert assembly robot provided in this embodiment, the top of the injection molding machine 1 is provided with a cleaning device. The cleaning device includes a sweeping mechanism and a dust removal mechanism. The sweeping mechanism is used to perform contact cleaning on the surface of the insert, and the dust removal mechanism is used to blow off the dust on the surface of the insert.

[0026] The cleaning mechanism includes a first motor 25, a mounting plate 36, multiple rotating cylinders 40, and multiple sprockets 26. A dust collection box 38 is fixedly installed on the top of the injection molding machine 1, and a filter screen 37 is fixedly installed inside the dust collection box 38. A dust collection device 24 is slidably installed on one side of the injection molding machine 1. One end of a dust collection pipe 22 is fixedly installed at the bottom of the dust collection box 38, and the other end of the dust collection pipe 22 is fixedly connected to the dust collection device 24. The mounting plate 36 is fixedly installed inside the dust collection box 38. Multiple rotating cylinders 40 are rotatably mounted on the mounting plate 36, and each of the multiple rotating cylinders 40 has a cleaning brush 35 fixedly installed on its top. The first motor 25 is fixedly installed on one side of the outer wall of the dust collection box 38. Multiple sprockets 26 are respectively fixedly installed on the outer wall of the multiple rotating cylinders 40 and on the output shaft of the first motor 25, and the same chain 39 is sleeved on the outer side of the multiple sprockets 26. When the insert is fed into the mold, dust and debris will adhere to the surface of the insert through electrostatic adhesion. At this time, the injection molding machine 1 is started. When the gantry robot 2 moves the gripped insert into the dust collection box 38, the first motor 25 starts and drives multiple rotating cylinders 40 to rotate synchronously through the sprocket 26 and chain 39. The cleaning brush 35 on the top of the rotating cylinder 40 rotates and contacts the surface of the insert, brushing away dust, debris and other impurities. At this time, the dust collection device 24 starts to generate negative pressure and sucks the impurities brushed off in the dust collection box 38 through the dust collection pipe 22, completing the contact cleaning. This can remove the dust and debris electrostatically adsorbed on the surface of the insert before it enters the mold, avoiding impurities from entering the cavity and causing product defects, and greatly improving the appearance quality and yield of the injection molded product. The first motor 25 drives multiple rotating cylinders 40 and the cleaning brush 35 to rotate synchronously through the sprocket 26 and chain 39 to physically clean the surface of the insert. The dust collection device 24, dust collection pipe 22 and filter screen 37 promptly remove impurities to prevent secondary dust pollution.

[0027] The dust removal mechanism includes a high-pressure ion generator 42, an air pump 41, a second motor 28, multiple nozzles 34, and two strip rods 33. A baffle 23 is fixedly installed on one side of the outer wall of the dust collection box 38. The top of the baffle 23 has an opening. Multiple nozzles 34 are rotatably mounted on the inner wall of the opening. A three-way pipe is fixedly installed at the inlet end of each nozzle 34. The high-pressure ion generator 42 is fixedly installed on one side of the outer wall of the baffle 23. One end of a second multi-head pipe 30 is fixedly installed on the high-pressure ion generator 42. The other ends of the second multi-head pipe 30 are respectively fixedly connected to the three-way pipes. The air pump 41 is fixedly installed on one side of the outer wall of the baffle 23. One end of a first multi-head pipe 29 is fixedly installed at the exhaust port of the air pump 41. The other ends of the first multi-head pipe 29 are respectively fixedly connected to the three-way pipes. Do not fix it to the three-way pipe. The high-pressure ion generator 42 adopts the existing technology of a high-pressure ion generator with a built-in fan. When the high-pressure ion generator 42 discharges positive and negative ions into the three-way pipe through the second multi-head pipe 30, the air pump 41 inputs a large amount of gas into the three-way pipe through the first multi-head pipe 29 and applies air pressure to mix the positive and negative ions with the gas and spray it out quickly. Both strip rods 33 are slidably installed on the top of the baffle 23. The two strip rods 33 are connected by a drive. The top of both strip rods 33 is fixedly installed with racks 31. The top of the baffle 23 is rotatably installed with gears 32. Both racks 31 mesh with gears 32. The second motor 28 is fixedly installed on the top of the baffle 23. The output shaft of the second motor 28 is fixedly installed with a cam 27. The top of nozzle 7 is provided with a guide groove. One end of one of the strip rods 33 has a protrusion fixedly installed at its bottom. The bottom end of the protrusion extends into the guide groove, and the protrusion is slidably connected to the guide groove. One end of a telescopic rod 43 is fixedly installed on the outer wall of multiple nozzles 34. The other end of the multiple telescopic rods 43 is rotatably connected to two strip rods 33 respectively. The telescopic rod 43 includes a fixed sleeve and a movable rod. The movable rod is slidably installed in the fixed sleeve. The fixed sleeve is fixedly installed on the outer wall of the nozzle 34. One end of the movable rod is rotatably installed on the strip rod 33. The air pump 41 and the high-pressure ion generator 42 start synchronously. The air pump 41 delivers high-pressure airflow through the first multi-head pipe 29, and the high-pressure ion generator 42 delivers ion air through the second multi-head pipe 30. The two gases are mixed through a three-way pipe. Then, the ion air is sprayed out from the nozzle 34, and the second motor 28 is started. The output shaft of the second motor 28 drives the cam 27 to rotate. The guide groove of the cam 27 drives one of the strip rods 33 to slide back and forth through the protrusion. The two strip rods 33 are driven by the meshing of the top rack 31 and the gear 32 to achieve synchronous reverse sliding. The strip rods 33 drive the nozzle 34 to swing back and forth in the opening of the baffle 23 through the telescopic rod 43, expanding the ion air blowing range. The ion air eliminates the static electricity on the surface of the insert and blows off the residual dust. It works with the dust collection device 24 to complete the secondary dust removal. Through the cooperation of the dust removal mechanism and the internal components, the air pump 41 and the high-pressure ion generator 42 respectively deliver high-pressure airflow and positive and negative ions to the three-way pipe through the first multi-head pipe 29 and the second multi-head pipe 30.The resulting ionized airflow is ejected from nozzle 34, quickly neutralizing static electricity in the inserts and removing residual dust. The second motor 28 drives cam 27 to rotate, which, in conjunction with rack 31 and gear 32, drives two strip-shaped rods 33 to slide synchronously in opposite directions. This, in turn, pulls nozzle 34 back and forth via telescopic rod 43, achieving multi-angle, full-coverage cleaning without any blind spots.

[0028] In this embodiment: When the insert is fed into the mold, dust and debris will adhere to the surface of the insert due to electrostatic adhesion. At this time, the cleaning device on the top of the injection molding machine 1 is activated. When the gantry robot 2 moves the gripped insert into the dust collection box 38, the first motor 25 is started. Through the sprocket 26 and chain 39, multiple rotating cylinders 40 are driven to rotate synchronously. The cleaning brush 35 on the top of the rotating cylinder 40 rotates and contacts the surface of the insert to brush away dust, debris and other impurities. At this time, the dust collection device 24 is activated to generate negative pressure and sucks the impurities brushed off in the dust collection box 38 through the dust collection pipe 22 to complete the contact cleaning. Subsequently, the air pump 41 and the high-pressure ion generator 42 start synchronously. The air pump 41 delivers high-pressure airflow through the first multi-head pipe 29, and the high-pressure ion generator 42 delivers ion wind through the second multi-head pipe 30. After the two gases are mixed through the three-way pipe, they are sprayed out from the nozzle 34. Then, the second motor 28 is started. The output shaft of the second motor 28 drives the cam 27 to rotate. The guide groove of the cam 27 drives one of the strip rods 33 to slide back and forth through the protrusion. The two strip rods 33 are driven by the meshing of the top rack 31 and the gear 32 to achieve synchronous reverse sliding. The strip rods 33 drive the nozzle 34 to swing back and forth in the opening of the baffle 23 through the telescopic rod 43, expanding the ion wind sweeping range. The ion wind eliminates the static electricity on the surface of the insert and blows off the residual dust completely. It works with the dust collection device 24 to complete the secondary dust removal. After cleaning, the gantry robot 2 removes the cleaned insert from the dust collection box 38 and proceeds to the subsequent alignment.
