Description

Technical Field

[0001] This utility model relates to the field of automotive lighting production technology, specifically to a material handling device for injection molding of automotive lighting housings. Background Technology

[0002] A car headlight housing is a frame used to mount and fix the light-emitting components of a car headlight. It is a plastic product and is injection molded into a single piece using an injection molding machine. When removing the molded housing from the mold, because the surface temperature of the freshly molded housing is high, a specialized material removal device is typically used to remove the housing from the mold to prevent burns to workers.

[0003] For example, Chinese patent document CN220946520U discloses a material handling and protection device for injection molding of automotive headlights, including a base, an outer frame fixed to the top of the base, a sliding door slidably provided on one side of the outer frame, a motor mounted on the base, a heating tube for heating plastic granules on the motor, a feeding screw rotatably connected inside the heating tube, the feeding screw being connected to the output shaft of the motor via a coupling, the operation of the motor causing the output shaft to drive the feeding screw to rotate for material conveying, a support frame fixed to the base, and a storage frame connected and communicating with the heating tube on the support frame, the storage frame being used to feed plastic granules into the heating tube.

[0004] In the above technical solution, the car headlight is clamped and removed from the outer frame by controlling the movement of the robotic arm and coordinating with the opening and closing clamps, thus achieving automatic and rapid material handling and ensuring safe and efficient production. However, when handling materials with the robotic arm, the sliding door of the injection molding machine needs to be opened before the grabbed headlight housing can be taken out, and the sliding door needs to be closed again during injection molding, so there are some inconveniences in the material handling process. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a material handling device for injection molding of automotive lamp housings, which can optimize the material handling process and improve the convenience of material handling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material handling device for injection molding of automotive lamp housings, comprising a base, an outwardly extending connecting portion on the base, a first slide table on the connecting portion that can slide along the extension direction of the connecting portion, an outwardly extending connecting seat on the first slide table, a second slide table on the connecting seat that can slide along the extension direction of the connecting seat, a vertically arranged mounting seat fixed on the second slide table, a mounting cavity inside the mounting seat, a telescopic rod inside the mounting cavity, an adsorption mechanism connected to the end of the telescopic rod, and a driving cylinder outside the mounting seat for driving the adsorption mechanism to lift and lower, so as to remove the lamp housing adsorbed by the adsorption mechanism from the injection molding machine.

[0007] The present invention is further configured such that: the telescopic rod includes a first connecting section and a second connecting section, the first connecting section is embedded in the mounting cavity and adapted to the mounting cavity, the second connecting section is embedded in the first connecting section, a pulley is rotatably connected to one end of the first connecting section, a rope is fitted around the pulley, one end of the rope is fixed to the inner wall of the mounting base, and the other end extends into the first connecting section and is fixed to one end of the second connecting section. Through the transmission cooperation formed between the pulley and the rope, the first connecting section and the second connecting section can be linked to extend and retract. The output end of the drive cylinder is fixed to the outer wall of the first connecting section.

[0008] The present invention is further configured such that: the adsorption mechanism includes a bracket fixed to the end of the second connecting section, and a bidirectional lead screw and a guide rod arranged at intervals are connected to the bracket. The two ends of the bidirectional lead screw are respectively fitted with first movable seats that can form a threaded engagement with the bidirectional lead screw. The two first movable seats on both sides can move towards each other or away from each other through the bidirectional lead screw. The two ends of the guide rod are respectively fitted with second movable seats that can form a sliding engagement with the guide rod. A suction cup is fixed on both the first movable seats and the second movable seats. The second movable seat can move synchronously with the first movable seat.

[0009] The present invention is further configured such that: a synchronizing rod is provided between the first movable seat and the second movable seat, one end of the synchronizing rod is fixed to the first movable seat and the other end is fixed to the second movable seat.

[0010] The present invention is further configured such that one end of the bidirectional lead screw extends outward as an adjustment end, and the adjustment end is provided with an internal hexagonal hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Since the adsorption mechanism for grabbing the lamp housing is connected to a telescopic rod that is raised and lowered by a drive cylinder, when it is necessary to remove the molded lamp housing from the injection molding machine, the drive cylinder only needs to extend the telescopic rod from the top of the injection molding machine into the interior, and the adsorption mechanism can then grab the lamp housing from the mold. Afterwards, the telescopic rod can be retracted to remove the adsorbed lamp housing from the top of the injection molding machine. Therefore, there is no need to open the sliding door of the injection molding machine when picking up the material, which simplifies the material picking process and improves the convenience of automatic material picking. Thus, it effectively solves the technical problem of having to frequently open and close the sliding door of the injection molding machine when picking up the material in the prior art.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 4As shown, this utility model discloses a material handling device for injection molding of automotive lamp housings, including a base 1 fixed to the top of an injection molding machine. The base 1 has a connecting part 101 extending laterally outward. A first slide 2 driven by a corresponding motor is installed on the connecting part 101 to adjust its horizontal position. A longitudinally extending connecting seat 3 is vertically fixed on the first slide 2. A second slide 4 driven by a corresponding motor is installed on the connecting part 101. Both the first slide 2 and the second slide 4 are driven by ball screws, and both can use existing structures. Through the coordinated movement of the first slide 2 and the second slide 4, the precise positioning of the adsorption mechanism described below in the horizontal plane can be achieved.

[0020] The second slide 4 has a vertically mounted mounting base 5 fixed at its end. The mounting base 5 has a rectangular mounting cavity 51 inside, within which a telescopic rod is nested. This telescopic rod employs a multi-stage telescopic structure. Specifically, the top of the outer first connecting section 71 of the telescopic rod is equipped with a pulley 73. One end of a rope 74 is fixed to the inner wall of the mounting base 5, and the other end passes around the pulley 73 and connects to the top of the inner second connecting section 72. When the drive cylinder 6 on the outside of the mounting base 5 pushes the first connecting section 71 downwards, the rope 74 is pulled by tension, causing the second connecting section 72 to extend synchronously, forming a two-stage linkage telescopic movement. When the cylinder retracts, the second connecting section 72 returns to its original position under the transmission action of the pulley 73 and the rope 74. This design increases the telescopic stroke to twice that of a single-stage structure while reducing overall space occupancy.

[0021] Additionally, the adsorption mechanism connected to the end of the telescopic rod includes a bracket 81 fixed to the second connecting section 72. A bidirectional lead screw 82 and a guide rod 83 are arranged parallel to each other on the bracket 81. The two ends of the bidirectional lead screw 82 are rotatably connected to both sides of the bracket 81. Each end of the bidirectional lead screw 82 is fitted with a first movable seat 84 that forms a threaded engagement with each end of the bidirectional lead screw 82. A second movable seat 85 is slidably connected to the guide rod 83. The two are fixedly connected by a rigid synchronizing rod 9 to form a linkage structure. One end of the bidirectional lead screw 82 extends to the outside of the bracket 81 to form an adjusting end 821. The adjusting end 821 has an internal hexagonal hole 822. By rotating a wrench, the two movable seats can be driven to move towards or away from each other, thereby adjusting the distance between the suction cups 86. In this way, the distance between the suction cups 86 can be adjusted according to the specifications of the lamp housing to be adsorbed, thus expanding the applicable range.

[0022] The dual constraint of guide rod 83 and synchronization rod 9 ensures that the four suction cups 86 maintain linear synchronous movement during adjustment, avoiding unstable adsorption caused by skewness. The suction cups 86 adopt a vacuum adsorption method. After contacting the lamp housing surface, negative pressure is activated to stabilize the grip. The pump body that draws pressure inside the suction cup 86 is fixed to the bracket 81, and the pump body is connected to each suction cup 86 through an independent air tube.

[0023] The usage process of this utility model is as follows:

[0024] When the device is working, the adsorption mechanism is first moved to directly above the injection mold by the coordinated movement of the first slide 2 and the second slide 4. The drive cylinder 6 pushes the telescopic rod downward, so that the suction cup 86 contacts the surface of the lamp housing and adsorbs and fixes it. Then the drive cylinder 6 retracts, the telescopic rod rises and vertically removes the lamp housing, and the first slide 2 and the second slide 4 move in opposite directions to transfer the lamp housing to the conveyor belt. Therefore, when it is necessary to remove the molded lamp housing from the injection molding machine, the drive cylinder 6 only needs to drive the telescopic rod to extend into the injection molding machine from the top, and the adsorption mechanism can grab the lamp housing in the mold. Then, the telescopic rod retracts, and the adsorbed lamp housing can be removed from the top of the injection molding machine. Therefore, there is no need to open the sliding door of the injection molding machine when picking up the material, which simplifies the material picking process and improves the convenience of automatic material picking.

[0025] For lamp housings of different specifications, operators can quickly adjust the spacing of suction cups 86 by rotating the adjusting end 821 of the two-way lead screw 82 with an Allen wrench, making it compatible with multiple models without replacing any parts.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
