Description

Technical Field

[0001] This utility model belongs to the field of automated oil filling production technology, and in particular relates to an automated oil filling production line device. Background Technology

[0002] Engine oil is a lubricating product used in vehicles. By changing the engine oil, it lubricates gear systems such as the vehicle's transmission, thereby protecting the transmission system.

[0003] Therefore, engine oil has a very wide range of applications in industry, resulting in a relatively high market demand. The engine oil production line mainly includes an oil can feeding conveyor belt system. Empty oil cans are conveyed by the conveyor belt through a filling device, and then the oil information is printed onto the can casing using a coding device. After coding, the can opening is screwed on by a capping device, and finally sealed with an aluminum foil sealing device. The production line then feeds the packaging cartons containing the oil cans into a packing device, where the oil cans are packed into boxes.

[0004] After being packed, the boxes are transported by conveyor belt to the unloading station, where they are manually unloaded onto the palletizing platform and stacked, awaiting transport by forklifts.

[0005] It's clear that the production efficiency of the entire assembly line decreases at the tail end due to the manual unloading process. This is because the packaging boxes contain a certain number of filled oil cans, which are quite heavy and can only be handled manually.

[0006] A robotic arm is a type of robot used in industrial production for unloading or loading materials. Its main structure includes the robotic arm body and a gripper installed at the operating end of the robotic arm body. However, unlike unloading conventional products, the high density of the oil makes each bottle slightly heavier, and the overall weight of the packaged box is also slightly heavier. Therefore, the gripper on a conventional robotic arm is simply unable to stably hold the packaged oil bottles and achieve automatic unloading.

[0007] Therefore, by using a gripper with high gripping stability in conjunction with the automated operation of the robotic arm, the robotic arm can unload materials, which not only fundamentally solves the problem of low efficiency in unloading during the production process, but also saves a lot of manpower. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide an automated oil filling production line device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An automated oil filling production line device includes a conveyor belt device, on which a filling device, a capping device for oil cans, a coding device, an aluminum foil sealing device, a packaging box feeding device, an oil can packing device, a packaging box sealing device, and a feeding device are sequentially assembled and connected.

[0011] The feature is that the unloading device includes an unloading robot, which includes a robotic arm and a gripper mechanism installed at the operating end of the robotic arm;

[0012] The gripper mechanism includes a gripper bracket, on which several gripper arm units distributed at different positions are hingedly mounted; each gripper arm unit includes several gripper arms.

[0013] It also includes a push-pull structure for pushing and pulling several gripper arm units, wherein the push-pull structure includes several pushers, and the pusher end of the pusher is hinged to the gripper arm unit;

[0014] It also includes a bracket with several pushers hinged together.

[0015] Preferably, the gripper bracket includes a transverse frame portion arranged laterally and a longitudinal frame portion arranged perpendicular to the transverse frame portion;

[0016] Hinged beam supports are welded and fixedly connected to both ends of the transverse frame and the longitudinal frame, respectively.

[0017] The gripper arm units are respectively hinged and installed on the hinge beam support.

[0018] Preferably, the hinge beam support has a plurality of hinge interfaces, and the grab arms are respectively hinged in the hinge interfaces;

[0019] A long hinge pin is fixedly connected to the hinge beam bracket, and the grab arm is fixedly connected to the long hinge pin.

[0020] Preferably, the gripper arm includes a V-shaped main arm portion, which is fixedly mounted on a long hinge pin.

[0021] The main arm is integrally formed with an outwardly inclined clamping arm portion;

[0022] After the push-pull structure pulls the gripper arm to flip, the clamping arm changes from an inclined position to a vertical clamping position.

[0023] Preferably, a rubber pad for increasing clamping friction is fixedly connected to the inner wall of the clamping arm, and the rubber pad has a plurality of protruding ribs for increasing friction integrally formed.

[0024] Preferably, the push-pull structure includes four push-pull components that respectively push-pull gripper arm units;

[0025] The push-pull component includes a cylinder.

[0026] Preferably, the piston rod of the cylinder is fixedly connected to a push-pull rod, and a first hinge seat is fixedly connected to the inner side wall of the main arm, and the push-pull rod is hinged to the first hinge seat;

[0027] The cylinder barrel is hinged and mounted on the bracket.

[0028] Preferably, the cross-sectional shape of the bracket is cross-shaped;

[0029] A second hinge seat is fixedly connected to the cylinder barrel of the cylinder, and the second hinge seat is hinged to the end of the bracket.

[0030] A top mounting rod is fixedly installed on the top of the bracket, and the top mounting rod is fixedly installed on the bottom of the gripper bracket.

[0031] Preferably, a connecting seat is fixedly installed at the top center of the gripper bracket, and the connecting seat is installed on the operating end of the robotic arm.

[0032] This utility model has the following beneficial effects:

[0033] 1. Based on the existing industrial production material unloading robot arm structure, this utility model designs a material unloading gripper that works in conjunction with the robot arm. By improving the material unloading gripper, finished product packaging boxes can be unloaded stably and safely to support efficient production line operations, while reducing the intensity of manual labor and improving the safety of material unloading.

[0034] 2. With four gripping arm units located in the front, back, left, and right directions respectively, and the packaging box being a cuboid, the four gripping arm units designed in this way can grip each side of the packaging box during the gripping process, thereby improving gripping stability.

[0035] 3. Each gripper unit includes three equally spaced grippers, which enable three-stage gripping on each side wall of the packaging box during the gripping process. Therefore, 12 gripping points are formed on the overall cuboid-shaped packaging box. This method solves the technical drawback of not being able to stably grip and unload slightly heavier packaging boxes.

[0036] 4. The shape and features of the gripper arms enable more precise gripping of packaging boxes during operation. For example, when all gripper arms are in an outward-opening position, the V-shaped main arm structure—with its outward-sloping clamping arms—creates a large gripping space, allowing the gripper to fully cover the packaging box area and secure it during the gripping process. When the gripper arms are closed, the V-shaped main arm design allows all gripper arms to come together fully and grip the packaging box tightly. Attached Figure Description

[0048] Example 1

[0049] like Figure 1-6 As shown, an automated oil filling production line device includes an automated filling production line, which has the same structure as an existing filling production line for filling oil, including a conveyor belt device 9. After the empty oil can is manually fed from the feed end position 1 of the conveyor belt device 9, it is discharged after going through the following process.

[0050] Specifically, the conveyor belt device 9 is sequentially equipped with a filling device 2 connected to a filling mechanism, and a capping device 3 for a capping oil can is located downstream of the filling device 2 (the capping device 3 includes an oil can cap cover device 31 and a cap tightening device 32 for tightening the oil can cap to the oil can opening). Downstream of the capping device 3, a coding device 4 (for spraying information about the engine oil onto the oil can) and an aluminum foil sealing device 5 (for further sealing the oil can cap with aluminum foil) are located. The engine oil filling process is completed through these steps, and then the oil enters the packaging process.

[0051] Specifically, the packaging box feeding device 7 feeds empty packaging cartons into the oil can packing device (the feeding method is that the operator feeds the empty packaging boxes onto the carton conveyor belt 71, which then enters the oil can packing device 6 for packing), the packaging box sealing device 61, and the unloading device.

[0052] The conveyor belt device 9, filling device 2, capping device 3, coding device 4, aluminum foil sealing device 5, oil can packing device 6, packaging box sealing device 61, and packaging box feeding device 7 in the aforementioned automated filling production line are all conventional structures in existing oil filling lines. Those skilled in the art can clearly understand the specific structure and working principle of each functional device in the aforementioned filling production line disclosed in this utility model by consulting technical manuals and dictionaries, based on the existing structure of oil filling production lines.

[0053] Since the overall weight of the packaging box after the oil can is packed is relatively large, the existing technology uses manual unloading to ensure a more stable and safer process. However, manual unloading is not only labor-intensive but also inefficient. Therefore, this utility model designs a unloading gripper that works in conjunction with the existing industrial production unloading robotic arm structure. By improving the unloading gripper, the finished packaging box can be unloaded stably and safely to support efficient production line operations, while reducing the intensity of manual labor and improving the safety of unloading.

[0054] Example 2

[0055] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 1, includes a feeding robot, which in turn includes a robotic arm 8. The robotic arm 8 is a conventional industrial production robotic arm 8 disclosed in the prior art. Similar to existing robotic arms 8, it can adjust its posture according to the material handling requirements during the feeding and gripping of packaging boxes. To enable the robotic arm 8 to grip packaging boxes containing organic oil products more stably, this invention improves the gripper mechanism based on the existing robotic arm 8.

[0056] Specifically, the gripper mechanism 81 at the operating end of the robotic arm 8.

[0057] The gripper mechanism 81 includes a gripper bracket 811, which has the following shape: the gripper bracket 811 includes a transverse frame portion arranged laterally and a longitudinal frame portion arranged perpendicularly to the transverse frame portion (i.e., the gripper bracket 811 is a cross-shaped bracket). Hinged beam brackets 8111 are welded and fixedly connected to the left and right ends of the transverse frame portion and the front and rear ends of the longitudinal frame portion, respectively. A gripper arm unit (in clockwise order, the first gripper arm unit 813, the second gripper arm unit 814, the third gripper arm unit 815, and the fourth gripper arm unit 816) is hinged to each hinged beam bracket 8111.

[0058] Therefore, the four gripping arm units are located in the front, back, left, and right directions, respectively. Since the packaging box is cuboid in shape, the four gripping arm units designed in this way can grip each side of the packaging box during the gripping process, thereby improving the gripping stability (avoiding the technical defects of insufficient gripping force and packaging box loosening).

[0059] Specifically, the first gripping arm unit, the second gripping arm unit, the third gripping arm unit, and the fourth gripping arm unit each include three equally spaced gripping arms 8131 (the gripping arms 8131 are hinged in the following way: the hinge beam bracket 8111 has three hinge interfaces, and the three gripping arms 8131 are respectively hinged in the hinge interfaces; at the same time, a long hinge pin A is fixedly connected to the hinge beam bracket 8111, and the gripping arms 8131 are fixedly connected to the long hinge pin A, so that the three gripping arms 8131 on each gripping arm unit can move as a whole).

[0060] The above structure enables three-stage gripping on each side wall of the packaging box during the material handling process. Therefore, 12 gripping points are formed on the overall cuboid-shaped packaging box. This method solves the technical drawback of not being able to stably grip and unload slightly heavier packaging boxes (the density of engine oil is high, and if four bottles of engine oil are packaged in a single box, the weight of the packaging box will be large).

[0061] Meanwhile, the four gripper arm units are driven by a push-pull structure. Specifically, during the gripping process, the push-pull structure is used to simultaneously grip a total of 12 grippers 8131 on the outer wall of the box.

[0062] Specifically, the push-pull structure includes four pushers, each with its push end hinged to the gripper arm unit; it also includes a bracket that hinges to mount several pushers.

[0063] Specifically, each push-pull component includes a cylinder 818. The piston rod of the cylinder 818 is fixedly connected to a push-pull rod 8181, and a first hinge seat B (specifically welded and fixed to the main arm portion of the gripper arm 8131) is fixedly connected to the inner wall of the corresponding gripper arm 8131. The push-pull rod 8181 is hinged to the first hinge seat B (the hinge is achieved by a pin).

[0064] Similarly, the cylinder barrels of the four cylinders 818 are hinged and mounted on the bracket 817. The cross-sectional shape of the bracket 817 is cross-shaped.

[0065] A second hinge seat is fixedly connected to the cylinder barrel of cylinder 818, and the second hinge seat is hinged to the end of bracket 817 (similarly hinged by a pin).

[0066] A top mounting rod is fixedly installed on the top of the aforementioned bracket 817, and the top mounting rod is fixedly installed on the bottom of the gripper bracket 811.

[0067] During operation, the four cylinders 818 work synchronously (synchronous operation of multiple cylinders 818 is a conventional working method disclosed in the prior art, and those skilled in the art can know how four cylinders 818 work synchronously by consulting technical manuals and dictionaries) to pull the four grab arm units synchronously. During the pulling process, each grab arm unit flips over and is clamped onto the packaging box by the grab arm 8131.

[0068] According to the existing gripper installation method on the robotic arm 8, a connecting seat 812 is fixedly installed at the top center of the gripper bracket 811. The connecting seat 812 is installed on the operating end of the robotic arm 8 (specifically, the connecting seat body of each is fixedly connected to the operating end of the robotic arm 8, which is the same as the existing gripper fixture structure of the robotic arm 8, and the two are connected by means such as bolts).

[0069] Similar to existing methods, the robotic arm 8 grabs the packaging box and places it on the palletizing plate 10, waiting for subsequent forklift transport.

[0070] Example 3

[0071] like Figure 1-6 As shown, based on the structure of Embodiment 1, the gripper 8131 includes a V-shaped main arm portion, which is fixedly mounted on a long hinge pin. The main arm portion is integrally formed with an outwardly inclined clamping arm portion. After the push-pull structure pulls the gripper 8131 to flip, the clamping arm portion switches from an inclined posture to a vertical clamping posture.

[0072] The gripper arm 8131 with the above-mentioned structural design can grasp the packaging box more accurately during the working process. For example, when all gripper arms 8131 are in the outward flipped position, the gripping space of the clamping arm is large after the main arm part with the V-shaped structure and the clamping arm part with the outward tilt is opened, so that the clamping area can be fully covered during the gripping process to grasp the packaging box.

[0073] After the gripper 8131 is closed, the V-shaped main arm design allows all grippers 8131 to come together fully and grip the packaging box tightly.

[0074] Meanwhile, in order to increase the stability of gripping, according to the existing method, a rubber pad 8132 for increasing gripping friction is fixedly connected to the inner wall of the clamping arm. The rubber pad 8132 has several protruding rib structures for increasing friction integrally formed.

[0075] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
