Description
Technical Field
[0001] The present invention relates to the technical field of automotive parts production, and particularly to an intelligent fully automatic production line for injection molded parts. Background Art
[0002] An automotive grille is provided at the front of an automobile to facilitate the intake of air into the engine compartment and the dissipation of engine heat. At the same time, the automotive grille also serves to decorate the automobile. When the existing automotive grille is processed, steps such as injection molding, trimming the sprue, injection handling, hot stamping production, warehousing and storage, parts assembly, assembly inspection, assembly packaging, and transportation to the finished product warehouse are adopted. With the improvement of the automation level of the whole vehicle production line, the production rhythm of the parts on the corresponding whole vehicle is getting faster and faster, which also requires an increase in the automation level of parts production.
[0003] Currently, the improvement of the automation level of grille injection molded parts can focus on two directions. First, the automation of the processing of the three parts of injection molding, trimming the sprue, and hot stamping production; second, the automatic transmission and storage of grille injection molded parts; for the second aspect, the current storage still relies on manual transfer and storage. When there is a pile-up of grille injection molded parts in each processing step, transfer and storage are required; the operation steps of transfer and storage are mainly reflected in the process of assembly and transportation to the finished product warehouse of the parts assembly after the hot stamping production of grille injection molded parts, which consumes a large amount of manpower and has a low transfer and storage efficiency; at the same time, affected by the storage space, the grille injection molded parts need to be placed vertically on a relatively high storage rack. When manually handling and storing, there are difficulties in storage, and it will further affect the transfer and storage efficiency.
[0004] At the same time, after the injection molding of the grille injection molded parts, burrs are likely to exist at the gate of the grille injection molded parts. Before hot stamping production, the burrs need to be cut or polished and cleaned. Limited by the changes in the size and specifications of different specifications of grille injection molded parts, the gates of the grille injection molded parts are not on the same horizontal plane, and the cutting knife or polishing roller is in a fixed state, which will result in incomplete cleaning or poor cleaning effect during cutting or polishing and cleaning, and further affect the overall production efficiency of the grille injection molded parts. Summary of the Invention
[0005] In view of the deficiencies in the prior art, the present invention provides an intelligent fully automatic production line for injection molded parts to solve the problems of large consumption of manpower and low transfer and storage efficiency during the process of assembling grille injection molded parts and transporting them to the finished product warehouse.
[0006] To achieve the above object, the basic solution of the present invention is as follows: An intelligent fully automatic production line for injection molded parts, including an injection molding device, a first transfer device, a gate trimming device, a second transfer device, a hot stamping production device, a third transfer device, a parts assembly table, a fourth transfer device, and a storage transfer device arranged in sequence. The third transfer device is a first AGV cart, the fourth transfer device includes a second AGV cart, the storage device includes a first intelligent storage rack electrically connected to the first AGV cart and a second intelligent storage rack electrically connected to the second AGV cart. A first transfer robot for automatically transporting the grille injection molded parts is provided on the first intelligent storage rack, and a second transfer robot for automatically transporting the grille injection molded parts is provided on the second intelligent storage rack. A first conveying area is provided between the first intelligent storage rack and the hot stamping production device. The first AGV cart and the parts assembly table are located in the first conveying area. A second conveying area is provided between the second intelligent storage rack and the parts assembly table. The second AGV cart is located in the second conveying area.
[0007] The technical principle of the present invention is: When using the intelligent fully automatic production line for injection molded parts to process the grille injection molded parts, first use the injection molding device to inject the grille injection molded parts. After injection molding, use the first transfer device to transfer them to the gate trimming device. Then, the gate trimming device grinds the gate of the grille injection molded parts. After grinding, the second transfer device transfers the grille injection molded parts again and transfers them to the hot stamping production device for hot stamping processing. Then, use the first AGV cart to transfer the grille injection molded parts. The first AGV cart transports them to the first intelligent storage rack or the parts assembly table through the first conveying area. The grille injection molded parts that do not need to be assembled immediately are transported to the first intelligent storage rack by the first transfer robot. The grille injection molded parts that need to be assembled in time are transported to the parts assembly table for assembly. After the grille injection molded parts are assembled with other components, the second AGV cart transports them to the second intelligent storage rack through the second conveying area. The finished grille injection molded parts are transported to the second intelligent storage rack by the second transfer robot for storage.
[0008] In the above process, the first transfer device and the second transfer device can cooperate with the first AGV cart and the second AGV cart, so that the grille injection molded parts can be quickly transferred to the next processing step; at the same time, when using the first AGV cart and the second AGV cart to transfer the grille injection molded parts, it can feedback to the first AGV cart to transfer the grille injection molded parts to the parts assembly table or the first intelligent storage rack according to the assembly stock and the storage amount on the first intelligent storage rack, which is convenient for quickly assembling or transferring the grille injection molded parts. The transfer speed is fast, and the stock is also quickly adjusted, which can improve the processing efficiency of the grille injection molded parts.
[0009] Further, both the first transfer device and the second transfer device include a conveyor belt and a mechanical clamping arm for clamping the grille injection molding. Installation grooves for partial embedding of the grille injection molding are provided on the conveyor belts.
[0010] With the above settings, before grinding or hot stamping the grille injection molding, the mechanical clamping arm can be used to clamp and transfer the grille injection molding, enabling the grille injection molding to move quickly and stably to the processing station, facilitating rapid processing of the grille injection molding.
[0011] Further, a first conveying route for the first AGV cart to move is provided in the first conveying area. A number of first route codes for the first AGV cart to scan the route are set on the first conveying route. A number of second route codes for the second AGV cart to scan the route are set on the second conveying route. The first route codes are located on the vertical wall of the first conveying area, and the second route codes are also located on the vertical wall of the second conveying area.
[0012] With the above settings, the first AGV cart is first transported to the first intelligent storage rack or the parts assembly table through the first conveying area and the first route codes. After the grille injection molding is assembled with other components, the second AGV cart is transported to the second intelligent storage rack through the second conveying area and the second route codes. The first route codes and the second route codes can provide directions for the movement of the first AGV cart and the second AGV cart. At the same time, setting the first route codes and the second route codes on the vertical wall can prevent the first route codes and the second route codes from being worn and damaged, improving the service efficiency of the first route codes and the second route codes.
[0013] Further, the abrasive head device includes a grinding table, a grinding roller, a lifting control unit, and a first motor for driving the grinding roller to rotate. A grinding groove is provided on the upper surface of the grinding table. The first motor is installed on the vertical side wall of the grinding groove, and the axis of the grinding roller is parallel to the horizontal plane. The lifting control unit includes a first telescopic rod and a second telescopic rod. The axis of the first telescopic rod is perpendicular to the axis of the second telescopic rod. The first telescopic rod is arranged vertically or obliquely. The lower end of the first telescopic rod is connected to the bottom of the grinding table by a ball head. One end of the second telescopic rod is sleeved on the lower end of the first telescopic rod, and the other end of the second telescopic rod is hinged to the side wall of the grinding table. A suction cup for adsorbing the grille injection molding is provided at the upper end of the first telescopic rod.
[0014] With the above settings, the first transfer robot clamps the grille injection molding part into the grinding groove of the grinding table. At this time, the lower side of the grille injection molding part abuts against the suction cup, and the suction cup fixes the grille injection molding part. The gate is in contact with or abuts against the side wall of the grinding roller. Then, the first motor is started. The first motor can drive the grinding roller to rotate, and then deburr the gate of the grille injection molding part. At the same time, the lengths of the first telescopic rod and the two second telescopic rods are adjusted according to the position of the gate. The two second telescopic rods can push the first telescopic rod to rotate around the ball joint with the grinding table, and then the inclination direction of the gate can be adjusted. At the same time, the top of the first telescopic rod can lift the grille injection molding part as a whole as the first telescopic rod extends or retracts, so that the grinding roller can fit and grind the gate.
[0015] Furthermore, an annular moving groove is provided between the first motor and the vertical side wall of the grinding groove. The moving groove is coaxially arranged with the grinding groove. A conveyor belt is coaxially tensioned in the moving groove. The inner ring side wall of the conveyor belt is fixedly connected to the first motor. A transmission gear is fixedly installed on the outer ring side wall of the conveyor belt. A transmission wheel meshing with the transmission gear and a second motor driving the transmission wheel to rotate are provided in the grinding table. The second motor is fixedly connected to the grinding table.
[0016] With the above settings, when the second motor is started, after the transmission wheel meshes with the transmission gear on the conveyor belt, it drives the conveyor belt to rotate circumferentially in the moving groove. The conveyor belt synchronously drives the first motor and the grinding roller to rotate circumferentially along the inner wall of the grinding table, and then circumferentially grinds the gate of the grille injection molding part to achieve complete grinding of the gate.
[0017] Furthermore, a dust suction cavity is provided in the grinding table. The lower end of the dust suction cavity is connected to a negative pressure pump. A dust suction port is provided on the upper side of the dust suction cavity. The dust suction port is communicated with the grinding groove.
[0018] With the above settings, the negative pressure generated by the negative pressure pump can be transmitted to the dust suction port through the dust suction cavity, and then the waste chips generated during grinding are absorbed, reducing the adhesion amount of waste chips on the grille injection molding part after grinding and keeping the grille injection molding part in a relatively clean state.
[0019] Furthermore, the dust suction port is annular and is coaxially arranged with the conveyor belt.
[0020] With the above settings, the range of the dust suction port is large, which can ensure that the waste chips can be quickly and evenly adsorbed at the dust suction port.
[0021] Furthermore, a filter screen is fixedly installed between the negative pressure pump and the dust suction cavity.
[0022] With the above settings, it can prevent waste chips from entering the negative pressure pump, improve the service life of the negative pressure pump, and also facilitate the collection of waste chips.
[0023] Further, a connecting pipe is fixedly installed on the filter net, and the upper end of the connecting pipe is communicated with the suction cup through the dust suction cavity.
[0024] Through the above settings, part of the negative pressure of the negative pressure pump can be transmitted to the suction cup through the connecting pipe. Furthermore, the suction cup can fix the near-grille injection molded part, so that the grille injection molded part remains stable during grinding, making the grinding more accurate.

[0037] When the intelligent fully automatic production line for injection molded parts in this embodiment is in use, first, according to the entire intelligent fully automatic production line, the injection molding equipment 10 is used to inject the grille injection molded parts in sequence. After injection molding, the first transfer equipment 101 is used to transfer them to the gate grinding equipment 102. Then, the gate grinding equipment 102 grinds the gate of the grille injection molded parts. After grinding, the second transfer equipment 103 transfers the grille injection molded parts again and transports them to the hot stamping production equipment 104 for hot stamping processing. Then, the first AGV cart is used to transfer the grille injection molded parts. The first AGV cart is first transported to the first intelligent storage rack 202 or the parts assembly table 105 through the first conveying area and the first route code. The grille injection molded parts that do not need to be assembled immediately are transferred to the first intelligent storage rack 202 by the first transfer robot. The grille injection molded parts that need to be assembled in time are transported to the parts assembly table 105 for assembly. After the grille injection molded parts are assembled with other components, the second AGV cart is transported to the second intelligent storage rack 204 through the second conveying area and the second route code. The finished grille injection molded parts are transferred to the second intelligent storage rack 204 by the second transfer robot for storage.
[0038] When the gate grinding equipment 102 grinds the gate of the grille injection molded parts, the first transfer robot clamps the grille injection molded parts. The first transfer robot clamps the grille injection molded parts into the grinding groove 31 of the grinding table 30. At this time, the lower side of the grille injection molded parts abuts against the suction cup 604, and the gate of the grille injection molded parts faces upward and abuts against or is opposite to the side wall of the grinding roller 40. At this time, the first motor 401, the second motor 502, and the negative pressure pump 701 are turned on. The first motor 401 can drive the grinding roller 40 to rotate, thereby grinding the burrs at the gate of the grille injection molded parts. At the same time, the lengths of the first telescopic rod 601 and the two second telescopic rods 602 can be adjusted according to the position of the gate. The two second telescopic rods can push the first telescopic rod 601 to rotate around the ball joint connection with the grinding table 30, thereby being able to adjust the inclination direction of the gate. At the same time, the top of the first telescopic rod 601 can lift or lower the entire grille injection molded parts as the first telescopic rod 601 extends or retracts, so that the grinding roller 40 can be in contact with the gate for grinding.
[0039] At the same time, the second motor 502 drives the transmission wheel 503 to rotate. After the transmission wheel 503 meshes with the transmission teeth on the conveyor belt 501, it drives the conveyor belt 501 to rotate circumferentially in the moving groove 32. The conveyor belt 501 synchronously drives the first motor 401 and the grinding roller 40 to rotate circumferentially along the inner wall of the grinding table 30, thereby performing circumferential grinding on the gate of the grille injection molded parts and achieving complete grinding of the gate.
[0040] Meanwhile, the negative pressure generated by the negative pressure pump 701 can be transmitted to the dust suction port through the dust suction cavity 33, thereby absorbing the waste chips generated during grinding, reducing the adhesion amount of waste chips on the grille injection molding after grinding. A part of the negative pressure of the negative pressure pump 701 can be transmitted to the suction cup 604 through the connecting pipe 703, so that the suction cup 604 can fix the near grille injection molding, making the grille injection molding stable during grinding and making the grinding more accurate.
