Description

Technical Field

[0001] This utility model relates to the field of foaming equipment, specifically to a four-station foaming line for whole vehicle carpets. Background Technology

[0002] With the development of automobile production, car carpets need to be integrally molded using polyurethane foam. In the polyurethane foam production process, polyurethane foam material is poured into the bottom of the carpet blank (also known as the carpet surface). After it cures and solidifies, it is demolded, and the entire car carpet is formed.

[0003] Currently, vehicle carpets are produced by vehicle carpet foaming units. Each foaming unit requires a robotic arm, which drives the pouring head to pour foam material into the lower mold of the foaming unit. In order to increase production, multiple vehicle carpet foaming units are usually purchased. Since each foaming unit requires a robotic arm, the production equipment cost is high. There is an urgent need for a multi-station foaming line for vehicle carpets that only requires one robotic arm to meet production needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a four-station foaming line for whole vehicle carpets that only requires one robotic arm.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a four-station foaming line for whole-vehicle carpets, including: a foaming device, the structure of which includes: a mold frame, on which is a liftable upper plate, a lifting drive mechanism located above the upper plate for driving the upper plate to rise and fall, a download plate located directly below the upper plate, a flipping drive mechanism, a sliding trolley, and a trolley drive mechanism for driving the trolley to move. The download plate and the trolley are both located at the bottom of the mold frame. An upper mold is fixed on the lower surface of the upper plate, and a lower mold is fixed on the upper surface of the download plate. A blank mold for positioning the carpet blank layer is fixed on the trolley. The outer side of the front and rear sides of the download plate is connected to... The bottom of the mold frame is hinged. Driven by the flipping drive mechanism, the horizontal download plate can be flipped 90 degrees to an upright position, facilitating the removal of the foamed carpet from the lower mold. The upper mold has negative pressure holes, and the upper loading plate is equipped with an exhaust fan connected to these holes. When the exhaust fan operates, it generates suction in the negative pressure holes. After the download plate is driven to flip 90 degrees, it can avoid the trolley, allowing the trolley, driven by the trolley drive mechanism, to transport the carpet blank placed on the blank mold to directly below the upper loading plate. After the upper loading plate descends under the drive of the lifting drive mechanism, the upper mold can cover the blank mold. After the upper loading plate rises, the upper mold can hold the carpet through the negative pressure holes. The carpet blank is lifted by the upper mold, and after the lower platen returns to a horizontal position, the upper mold can close with the lower mold under the drive of the upper platen. At this time, the carpet blank is sandwiched between the upper and lower molds. After the foaming material poured on the lower mold cures and forms an integral part with the carpet blank, the whole carpet is obtained. The feature is that the trolley can slide left and right on the mold frame, and the trolley drive mechanism is used to drive the trolley to move left and right. The lower platen and the trolley are arranged side by side. There are four foaming devices, which are arranged in two rows and two columns. The trolleys of the two foaming devices on the left are located on the left side of their respective lower plates, and the trolleys of the two foaming devices on the right are located on their respective lower plates. On the right side, the download plates of the two front foaming devices are both set to flip forward 90 degrees to an upright position, and the download plates of the two rear foaming devices are both set to flip backward 90 degrees to an upright position. A track is set between the two front foaming devices and the two rear foaming devices. On the track are mounting seats that can slide left and right and mounting seat drive mechanisms for driving the mounting seats to move left and right. A robot arm is mounted on the mounting seat, and the pouring head is fixed to the robot arm. Driven by the mounting seat, the robot arm can move between the two front and rear foaming devices on the left or right side, so that the pouring head can pour for the four foaming devices under the drive of the robot arm.

[0006] Furthermore, in the aforementioned four-station foaming line for vehicle carpets, a large platform for placing supporting equipment is set above the four foaming devices, and the large platform is supported by the mold frames of the four foaming devices.

[0007] Furthermore, in the aforementioned four-station foaming line for whole vehicle carpets, a buffer platform is installed on the trolley, and several support columns are installed between the buffer platform and the trolley. The upper end of each support column is fixed to the buffer platform, and the lower end of each support column passes through a guide hole on the trolley. The guide hole can vertically guide the support column. A spring is installed on each support column, and the two ends of the spring abut against the trolley and the buffer platform respectively. When the buffer platform is pressed, the spring can provide a buffering force. The blank mold is installed on the buffer platform.

[0008] Furthermore, in the aforementioned four-station foaming line for vehicle carpets, the mold frame is equipped with four columns, which are located on the outer sides of the four corners of the upper plate. Linear guide rails are installed between the four corners of the upper plate and the four columns for vertical guidance. A gear is installed at each of the four corners of the upper plate, and a vertical rack is installed on each of the four columns. The four gears mesh with the racks that are closest to them. The two gears on the front side of the upper plate are mounted on both ends of a synchronous shaft, and the two gears on the rear side of the upper plate are mounted on both ends of another synchronous shaft. The two synchronous shafts are rotatably mounted on the upper plate via bearings.

[0009] Furthermore, in the aforementioned four-station foaming line for vehicle carpets, a plate is fixed on the upper surface of the upper loading plate. An elongated hole running vertically is formed on the plate. A pin seat is located at the top of the mold frame. Two load-bearing plates are mounted on the pin seat, each with a pin hole arranged opposite to the other. A pin and a cylinder for driving the pin are also mounted on the pin seat. The pin is inserted into one of the pin holes. After the upper loading plate rises, the plate can be inserted between the two load-bearing plates, allowing the elongated hole to be positioned between the two pin holes. At this point, the pin extends under the action of the cylinder and is inserted into both pin holes and the elongated hole. The pin then supports the upper loading plate through the plate.

[0010] Furthermore, in the aforementioned four-station foaming line for the whole vehicle carpet, a trigger boss is provided on the pin, and two photoelectric sensors are provided on the pin seat. When the pin is in the starting position and is inserted into only one pin hole, the trigger boss triggers one photoelectric sensor. When the pin extends and is inserted into two pin holes, the trigger boss triggers the other photoelectric sensor.

[0011] The advantages of this utility model are as follows: the four-station foaming line for whole vehicle carpets adjusts the relative positions of the trolley and the download plate in a single foaming device, and limits the positions of the four trolleys and the flipping direction of the four download plates in the four foaming devices, so that the four foaming devices can be arranged compactly together. Furthermore, by enabling the robotic arm to move left and right, only one robotic arm is needed to meet the production requirements for the four foaming devices, thereby greatly reducing the cost of production equipment.

[0017] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0018] like Figure 1 , Figure 3 , Figure 5As shown, the four-station foaming line for the whole vehicle carpet includes: a foaming device 5. The structure of the foaming device 5 includes: a mold frame 1, on which is a liftable upper platen 2, a lifting drive mechanism located above the upper platen 2 for driving the upper platen 2 to lift, a lower platen 3 located directly below the upper platen 2, a tilting drive mechanism, a sliding trolley 4, and a trolley drive mechanism for driving the trolley 4 to move. In this embodiment, the lifting drive mechanism and the tilting drive mechanism are both hydraulic cylinders. The lower platen 3 and the trolley 4 are both located at the bottom of the mold frame 1. An upper mold is fixed on the lower surface of the upper platen 2, a lower mold is fixed on the upper surface of the lower platen 3, and a blank mold for positioning the carpet blank layer is fixed on the trolley 4. The lower platen 3 has a blank mold on its front and rear sides. The outer side is hinged to the bottom of the mold frame 1. The two ends of the tilting cylinder are respectively hinged to the download plate 3 and the bottom of the mold frame 1. After the tilting cylinder extends, it can drive the horizontal download plate 3 to tilt 90 degrees to the vertical position, so as to facilitate the removal of the foamed whole carpet from the lower mold. A negative pressure hole is provided on the upper mold. A fan connected to the negative pressure hole is provided on the upper loading plate 2. After the fan is working, it can generate suction in the negative pressure hole. After the download plate 3 is driven to tilt 90 degrees, it can avoid the trolley 4. Under the drive of the trolley drive mechanism, the trolley 4 can transport the carpet blank layer placed on the blank mold to the bottom of the upper loading plate 2. After the upper loading plate 2 is lowered under the drive of the lifting drive mechanism, the upper mold can cover the blank mold. After the upper mold is raised, it can suck up the carpet blank through the negative pressure hole and lift the carpet blank. Then, after the lower platen 3 returns to the horizontal state, the upper mold can close with the lower mold under the drive of the upper platen 2. At this time, the carpet blank is sandwiched between the upper mold and the lower mold. After the foaming material poured on the lower mold is cured and formed into a whole with the carpet blank, the whole carpet is obtained. The trolley 4 can slide left and right on the mold frame 1. The trolley drive mechanism is used to drive the trolley 4 to move left and right. The lower platen 3 and the trolley 4 are arranged side by side. There are four foaming devices 5, which are arranged in two rows and two columns. The trolleys 4 of the two foaming devices 5 on the left are located on the left side of their respective lower plates 3, and the trolleys 4 of the two foaming devices 5 on the right are located below them. On the right side of the carrier plate 3, the download plates 3 of the two front foaming devices 5 are both set to flip forward 90 degrees to a vertical position, and the download plates 3 of the two rear foaming devices 5 are both set to flip backward 90 degrees to a vertical position. A track is set between the two front foaming devices 5 and the two rear foaming devices 5. A mounting seat 6 that can slide left and right is set on the track, and a mounting seat drive mechanism for driving the mounting seat 6 to move left and right is set. A robot arm 7 is mounted on the mounting seat 6, and the pouring head is fixed on the robot arm 7. Driven by the mounting seat 6, the robot arm 7 can move to the left or right between the two front and rear foaming devices 5, so that the pouring head can pour for the four foaming devices 5 under the drive of the robot arm 7.

[0019] In this embodiment, the trolley drive mechanism includes a meshing gear and a rack, with the rack mounted on the mold frame 1 and the gear mounted on the trolley and driven to rotate by a motor. The mounting base drive mechanism also includes a meshing gear and a rack, with the rack mounted on the track and the gear mounted on the mounting base and driven to rotate by a motor.

[0020] In this embodiment, a large platform 8 for placing supporting equipment is provided above the four foaming devices 5. The large platform 8 is supported by the mold frame 1 of the four foaming devices 5. This arrangement can reduce the floor space occupied.

[0021] like Figure 2 As shown, a buffer platform 9 is installed on the trolley 4, and several support columns 10 are installed between the buffer platform 9 and the trolley 4. The upper end of each support column 10 is fixed to the buffer platform 9, and the lower end of each support column 10 passes through a guide hole on the trolley 4. The guide hole can vertically guide the support column 10. A spring 11 is fitted on each support column 10, and the two ends of the spring 11 abut against the trolley 4 and the buffer platform 9 respectively. When the buffer platform 9 is pressed, the spring 11 can provide a buffering force. The blank mold is installed on the buffer platform 9. The blank mold is only used to position the carpet blank layer. The blank mold itself is not strong. Without buffering, the blank mold will be damaged after repeated pressing by the upper mold. Therefore, by setting up the buffer platform 9, the service life of the blank mold can be greatly extended.

[0022] like Figure 1 As shown, the mold frame 1 is equipped with four columns 12, which are located on the outer sides of the four corners of the upper plate 2. Linear guide rails are installed between the four corners of the upper plate 2 and the four columns 12 for vertical guidance. A gear 13 is installed at each of the four corners of the upper plate 2, and a vertical rack 14 is installed on each of the four columns 12. The four gears 13 mesh with the racks 14 closest to them. The two gears 13 on the front side of the upper plate 2 are mounted on both ends of a synchronous shaft 15, and the two gears 13 on the rear side of the upper plate 2 are mounted on both ends of another synchronous shaft 15. The two synchronous shafts 15 are rotatably mounted on the upper plate 2 via bearings. This arrangement ensures that the upper plate 2 remains horizontal during lifting and lowering as much as possible.

[0023] like Figure 4As shown, a plate 16 is fixed on the upper surface of the upper plate 2. An elongated hole 17 running vertically is provided on the plate 16. A pin seat 18 is provided at the top of the mold frame 1. Two load-bearing plates 19 are provided on the pin seat 18, each with a pin hole 20 arranged opposite to each other. A pin 21 and a cylinder for driving the pin 21 are also provided on the pin seat 18. The pin 21 is inserted into one of the pin holes 20. After the upper plate 2 rises, the plate 16 can be inserted between the two load-bearing plates 19, so that the elongated hole 17 is located between the two pin holes 20. At this time, the pin 21 extends under the action of the cylinder and can be inserted into both pin holes 20 and the elongated hole 17. The pin 21 then supports the upper plate 2 through the plate 16. This arrangement prevents the upper plate 2 from falling due to accidents, thereby improving production safety.

[0024] A trigger boss 22 is provided on the pin 21, and two photoelectric sensors 23 are provided on the pin holder 18. When the pin 21 is in the initial position and is inserted into only one pin hole 20, the trigger boss 22 triggers one photoelectric sensor 23. When the pin 21 extends and is inserted into both pin holes 20, the trigger boss 22 triggers the other photoelectric sensor 23. This configuration can detect whether the pin 21 has retracted into place or is fully inserted.
