Description

Technical Field

[0001] This invention relates to the field of automotive lamp cover processing technology, specifically to a material handling mechanism and method for injection molding production of automotive lamp covers. Background Technology

[0002] Headlight covers are installed on the exterior lights of a car. They are usually made of transparent or semi-transparent materials and are used to protect the exterior lights. During the driving process, the covers are easily impacted by external objects. Plastic has a much higher impact resistance than glass and is less likely to cause secondary injuries to people after breaking. Therefore, headlight covers are often made of plastic.

[0003] Injection molding is a highly efficient mass production method, with a production cycle typically taking only a few minutes. It is well-suited to the large-scale production needs of the automotive industry. Since lamp covers are optical components, even the smallest scratches, fingerprints, or oil stains can cause light scattering. Therefore, proper material handling can effectively improve the pass rate and production efficiency of lamp covers.

[0004] Furthermore, CN219708315U discloses an injection molding machine loading and unloading system. By setting up a box-type transfer mechanism, a handling robot, and a box-type transfer mechanism, the injection molding machine can connect with the handling robot through the box-type transfer mechanism and the box-type transfer mechanism to improve the handling efficiency and safety of plastic parts in loading and unloading operations. However, it still uses manual or robotic arms to load the plastic parts produced by the injection molding machine into the box or unload the plastic parts from the box. The freshly produced plastic parts still retain a high temperature, which can easily cause injury to personnel, and manual or robotic arm operation can easily cause additional damage to the plastic parts.

[0005] Furthermore, CN218859765U discloses a pick-and-place device for injection molded parts. By providing a pick-and-place component, it can pick up or release injection molded parts. By changing the spacing of the nozzles, it can change the spacing between the injection molded parts taken off the mold, thereby improving production efficiency. However, the pick-and-place component is a rigid coplanar structure, which cannot adapt to the curved surface of the lampshade. It can only adjust the spacing of the nozzles, but cannot adjust the angle and posture of the nozzles, and cannot stably pick up lampshades of different specifications.

[0006] Therefore, how to achieve safe and stable material feeding for automotive lamp covers has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide a material handling mechanism and method for injection molding production of automotive lamp covers, so as to solve the problems mentioned in the background art.

The connecting block passes through the through groove and is fixedly connected to the corresponding slider. A universal joint is connected to the side of the slider away from the slide rail. A negative pressure suction cup is connected to the end of the universal joint away from the slide rail.

[0009] According to the above technical solution, the injection molding machine includes a machine body and a production component. The moving component is located at the upper end of the injection molding machine. The moving component includes a base. The base is fixedly installed at the upper end of the machine body near the production component. An electric slide is fixedly installed at the upper end of the base. The electric slide includes a guide rail and a worktable. The guide rail is fixedly connected to the base, and the worktable is slidably connected to the guide rail.

[0010] According to the above technical solution, an electric slide table 2 is fixedly installed on the upper end of the workbench 1. The electric slide table 2 includes a guide rail 2 and a workbench 2. The workbench 2 is fixedly connected to the workbench 1. The guide rail 2 and the workbench 2 are slidably connected. A connecting plate is fixedly installed on the guide rail 2 in the direction of the production component. An electric slide table 3 is fixedly installed on the connecting plate in the direction of the production component. The electric slide table 3 includes a guide rail 3 and a workbench 3. The guide rail 3 is slidably connected to the connecting plate. The workbench 3 is slidably connected to the guide rail 3.

[0011] According to the above technical solution, a protective cover and a rack are fixedly installed on the same side of the guide rail three. The rack passes through the protective cover. A motor one is provided on the side of the protective cover facing the electric slide table two. The housing of the motor one is fixedly connected to the connecting plate. The output end of the motor one is inserted into the interior of the protective cover. A gear is fixedly installed on the output end of the motor one, and the gear meshes with the rack.

[0012] According to the above technical solution, the lifting column is fixedly installed on the side of the workbench three near the production component. The lifting column is located above the production component. A mounting base is provided at the bottom of the lifting column. The material picking component is located at the bottom of the lifting column. The rotating disk and the mounting base are connected by bearings. A second motor is fixedly installed on the outside of the mounting base. The output end of the second motor passes through the mounting base and is fixedly connected to the rotating disk.

[0013] According to the above technical solution, a number of line connectors are installed on one side of the lifting column, a drag chain is fixedly installed on the upper end of the base, the drag chain is located on the side of the moving component away from the production component, a number of lines are integrated inside the drag chain, an air pump is installed outside the injection molding machine, the air pump is connected to the negative pressure suction cup through a line, a pressure sensor is installed outside the negative pressure suction cup, and the probe of the pressure sensor is inserted into the inside of the negative pressure suction cup.

[0014] According to the above technical solution, the material handling method of the material handling mechanism for injection molding production of automotive lamp covers includes the following steps: Step 1: The injection molding machine completes the injection molding of the headlight cover.

[0015] According to the above technical solution, step two includes the following: Scenario 1: The lampshade surface is curved. Due to the difference in curvature between the two sets of negative pressure suction cups, they cannot simultaneously adhere to the lampshade surface, resulting in some structures of the negative pressure suction cups being suspended. The pressure sensor detects that the internal pressure of the negative pressure suction cup is not up to standard, and at this time, the negative pressure suction cup leaks air. The telescopic rod is used to adjust the adsorption position of the negative pressure suction cup to ensure stable adsorption.

[0016] According to the above technical solution, step two includes the following: Scenario 2: When the initial position of the negative pressure suction cup is directly opposite the irregular structure on the surface of the lampshade, the negative pressure suction cup cannot adsorb the lampshade at all. At the same time, the effective adsorption points of lampshades of different specifications are offset. The circumferential position of the negative pressure suction cup is adjusted by the motor and the rotating column.

[0017] According to the above technical solution, step two includes the following: Scenario 3: The center of gravity of the irregularly shaped headlight cover shifts, causing uneven force after the two sets of negative pressure suction cups adsorb the cover. During material handling, the cover may tilt or even fall off. The control module sends a correction signal to the material handling component to compensate for the center of gravity shift of the cover.

The installation directions of the two sets of slide rails 21 are opposite, that is, the opening directions of the through grooves 23 of the two sets of slide rails 21 are opposite (e.g., Figure 7As shown), telescopic rods 24 are provided on both sides of the slide rail 21.

[0028] A connecting block 26 is fixedly installed at the top of the output end of each telescopic rod 24. The connecting block 26 passes through the through groove 23 and is fixedly connected to the corresponding slider 25.

[0029] A universal joint 27 is connected to the side of the slider 25 away from the slide rail 21. A negative pressure suction cup 29 is connected to the end of the universal joint 27 away from the slide rail 21. A pressure sensor 28 is installed on the outside of the negative pressure suction cup 29. The probe of the pressure sensor 28 is inserted into the inside of the negative pressure suction cup 29.

[0030] Several line connectors 30 are installed on one side of the lifting column 11. A drag chain 31 is fixedly installed on the upper end of the base 3. The drag chain 31 is located on the side of the moving component 2 away from the production component 102. Several lines (not shown in the figure) are integrated inside the drag chain 31. Various lines are used to provide power to each actuator and to transport the air sucked by the negative pressure suction cup 29. The line connectors 30 facilitate the connection between each actuator of the material picking component 13 and the lines. An air pump (not shown in the figure) is installed outside the injection molding machine 1. The air pump is connected to the negative pressure suction cup 29 through a line and is used to draw air from inside the negative pressure suction cup 29 to create a negative pressure inside the negative pressure suction cup 29.

[0031] This invention also discloses a material handling method for a material handling mechanism used in the injection molding production of automotive lamp covers, comprising: Step 1: Injection molding machine 1 completes the injection molding of the car headlight cover. The finished headlight cover is cooled and demolded in production component 102, completing the preliminary preparation for material removal. The working principle of injection molding machine 1 is the existing technology.

[0032] Step 2: The moving component 2 moves the material picking component 13 to the top of the lampshade to be picked up, and uses the negative pressure suction cup 29 to stably adsorb the lampshade, thereby picking up the lampshade.

[0033] Specifically, the control module sends a working signal to the electric slide 4, which drives the worktable 402 to move along the guide rail 401. The worktable 402 drives the electric slide 5 to move synchronously along the guide rail 401. The control module sends a working signal to the electric slide 5. Since the worktable 502 is fixedly connected to the worktable 402, when the electric slide 5 is working, the guide rail 501 moves relative to the worktable 502 towards the production component 102. The guide rail 501 drives the electric slide 7 to move towards the production component 102. The electric slide 7 drives the lifting column 11 and the material picking component 13 to move towards the production component 102. By using the electric slide 4 and the electric slide 5 working together, the horizontal and vertical movement of the material picking component 13 in the plane space above the production component 102 is realized, expanding the working range of the material picking component 13 and adapting to the material picking needs of more specifications of lampshades.

[0034] The control module sends a working signal to motor 10, causing the output end of motor 10 to rotate, which in turn drives the gear to rotate. The gear drives rack 9 to move in a direction perpendicular to injection molding machine 1. Since rack 9 is fixedly connected to electric slide 7, electric slide 7 moves in a direction perpendicular to injection molding machine 1. The control module sends a working signal to electric slide 7, causing worktable 702 to move along guide rail 701. Worktable 702 drives lifting column 11 to move along guide rail 701. Lifting column 11 drives material picking component 13 to move in a direction perpendicular to injection molding machine 1. The control module can send working signals to motor 10 or electric slide 7 individually to adjust the height position of material picking component 13. Through motor 10 and electric slide 7, progressive movement of material picking component 13 in a direction perpendicular to injection molding machine 1 is achieved. Moving component 2 enables linear translation of material picking component 13 along three orthogonal directions: X-axis, Y-axis, and Z-axis, providing three-dimensional motion capability and further expanding the working range of material picking component 13 to meet different material picking needs.

[0035] The moving component 2 drives the material-picking component 13 to move. When the negative pressure suction cup 29 contacts the surface of the lampshade, the negative pressure suction cup 29 bears the reaction force generated by the lampshade. The negative pressure suction cup 29 transmits the reaction force to the universal joint 27. Under the influence of the reaction force, the universal joint 27 rotates. On the one hand, it avoids the negative pressure suction cup 29 from damaging the surface of the lampshade. On the other hand, it passively adjusts the angle of the negative pressure suction cup 29 so that the negative pressure suction cup 29 is in contact with the surface of the lampshade. The control module sends a working signal to the air pump, and the air pump extracts the air from inside the negative pressure suction cup 29. The pressure sensor 28 detects the pressure inside the negative pressure suction cup 29 to ensure that a negative pressure is formed inside the negative pressure suction cup 29, so as to achieve the adsorption of the lampshade.

[0036] After the lampshade is adsorbed, the moving component 2 drives the picking component 13 to move again, thereby removing the adsorbed lampshade from the production component 102 and transporting it to the storage area of ​​the finished lampshade.

[0037] In step two, based on actual production needs, the shape and structure of lampshades of different specifications vary. The curved surface, surface ribs, steps, chamfers and other irregular structures of the lampshade may cause the negative pressure suction cup 29 to fail to achieve effective adsorption. The negative pressure environment inside the negative pressure suction cup 29 is monitored in real time by the pressure sensor 28 to determine the adsorption state of the negative pressure suction cup 29. The stable adsorption of the lampshade is ensured by adjusting the different working states of the material picking component 13.

[0038] The specific implementation method is as follows: Scenario 1: The lampshade surface is curved. Due to the difference in curvature of the two sets of negative pressure suction cups 29, they cannot simultaneously adhere to the lampshade surface, resulting in part of the structure of the negative pressure suction cup 29 being suspended. The pressure sensor 28 detects that the internal pressure of the negative pressure suction cup 29 is not up to standard. At this time, the negative pressure suction cup 29 leaks air. The suction position of the negative pressure suction cup 29 is adjusted using the telescopic rod 24 to ensure stable suction.

[0039] Specifically, the control module sends a working signal to the telescopic rod 24 corresponding to the negative pressure suction cup 29 whose pressure is insufficient. The telescopic rod 24 drives the connecting block 26 to move along the through groove 23. The connecting block 26 drives the slider 25 to move along the slide rail 22. The slider 25 drives the universal joint 27 to move. The universal joint 27 drives the negative pressure suction cup 29 to move. By utilizing the rotation characteristics of the universal joint 27, the adsorption angle of the negative pressure suction cup 29 is adjusted within a small range to ensure stable adsorption.

[0040] Scenario 2: When the initial position of the negative pressure suction cup 29 is directly facing the irregular structure such as ribs, steps, and chamfers on the surface of the lampshade, the negative pressure suction cup 29 cannot adsorb the lampshade at all. At the same time, the effective adsorption point of different specifications of lampshade is offset. The circumferential position of the negative pressure suction cup 29 is adjusted by using motor 3 18 and rotating column 19.

[0041] Specifically, the control module sends a working signal to motor 3 18, the output end of motor 3 18 rotates, driving the rotating column 19 to rotate, the rotating column 19 drives the picking plate 20 to rotate, the picking plate 20 drives the fixedly connected actuators to rotate, realizing the rotation of the negative pressure suction cup 29 in the circumferential direction. At this time, the two sets of negative pressure suction cups 29 rotate synchronously, adjusting the suction position of the negative pressure suction cup 29.

[0042] It should be noted that when the negative pressure suction cup 29 leaks air, a small adjustment can be made using the method described in Case 1 to ensure stable adsorption while saving operation time. When the negative pressure suction cup 29 is completely unable to adhere to the lampshade, adjust the movement of the negative pressure suction cup 29 by following the steps in Case 2, select a new adsorption position, and ensure stable adsorption.

[0043] Scenario 3: The center of gravity of the irregularly shaped headlight cover shifts, causing uneven force after the two sets of negative pressure suction cups 29 adsorb the cover. During material picking, the cover may tilt or even fall off. The control module sends a correction signal to the material picking component 13 to compensate for the center of gravity shift of the cover.

[0044] Specifically, after adsorption is completed, the pressure sensor 28 provides real-time feedback on the pressure data of the two sets of suction cups. The control module calculates the pressure ratio. If the ratio exceeds the range of 0.8 to 1.2, it is determined that the center of gravity is off-center. The side with lower pressure is the side where the center of gravity of the lampshade is off-center, and the control module sends a correction signal.

[0045] After each set of actuators receives the correction signal, the negative pressure suction cup 29 on the side of the center of gravity offset releases the negative pressure adsorption state, activates the corresponding telescopic rod 24, adjusts the adsorption position, and performs secondary adsorption until the pressure ratio of the two sets of negative pressure suction cups 29 is reduced to the range of 0.8 to 1.2.

[0046] Furthermore, if the pressure ratio of the negative pressure suction cup 29 on the offset side still exceeds the reasonable range after multiple adsorptions, the adsorption state of the other set of negative pressure suction cups 29 is released, and the position of the two sets of negative pressure suction cups 29 is adjusted using the telescopic rod 24 to keep the spacing of the negative pressure suction cups 29 adapted to the size of the lampshade and avoid ineffective adsorption. The spacing and position between the two sets of negative pressure suction cups 29 are adjusted until the pressure ratio of the negative pressure suction cups 29 is reduced to a reasonable range.

[0047] Furthermore, if a suitable location cannot be found in the horizontal direction, the negative pressure suction cup 29 is rotated circumferentially through the operation in Case 2, so that the center of gravity of the lampshade falls on the area connecting the centers of the two sets of suction cups for adsorption.
