Description

A flipping device for high-temperature conditions in the glass viewing window of a washing machine. Technical Field

[0001] This utility model relates to the field of glass molding, specifically a flipping device for a high-temperature observation window of a washing machine. Background Technology

[0002] In the manufacturing process of washing machine glass viewing windows, it is necessary to flip the newly formed, high-temperature glass viewing window. Existing technology uses vacuum suction cups to grip the bottom of the viewing window and then rotates it. However, as market demands for washing machine viewing window manufacturing processes increase, the proportion of viewing windows with irregularly shaped bottoms is growing. This makes the existing suction cup-based flipping devices unable to grip irregularly shaped windows, forcing manual flipping during production and increasing the workload for operators. Therefore, there is a need to develop a flipping device that can accommodate irregularly shaped washing machine viewing windows to meet market demands. Summary of the Invention

[0003] In view of the current state of the technology, this utility model provides a flipping device for the glass observation window of a washing machine under high temperature conditions, which can meet the requirements of flipping the irregularly shaped observation window of the washing machine and solves the limitation of the existing vacuum suction cup on the scope of use of the washing machine observation window flipping.

[0004] To achieve the above objectives, the technical solution of this utility model is: a flipping device for a washing machine glass viewing window under high temperature conditions, including a bracket and a lifting mechanism mounted on the bracket, the lifting mechanism being connected to a guide mechanism, a lifting frame and a flipping mechanism mounted on the lifting frame being installed on the guide mechanism, and a rotating arm and clamping mechanisms mounted at both ends of the rotating arm being provided on the flipping mechanism.

[0005] In this invention, the lifting mechanism includes a lifting servo motor and a lifting reduction motor connected together. The lifting reduction motor is mounted on a lower fixed guide plate. The lifting reduction motor is connected to a lead screw. The lead screw and the lead end of the lifting bearing on the lower fixed guide plate are connected to a nut on the lifting plate of the guide mechanism. The displacement of the lowering plate is controlled by the lead screw.

[0006] In this invention, the guiding mechanism includes a lifting plate, on which four sliding guide columns are fixedly mounted. The four sliding guide columns pass sequentially through the corresponding guide holes on the top and lower guide plates of the support. Nuts are provided on the lifting plate and are connected to the lead screw of the lifting mechanism through the nuts.

[0007] In this invention, the flipping mechanism includes a variable-diameter rotating shaft, a flipping bearing mounted on the variable-diameter rotating shaft is installed inside a bushing, and is mounted on a lifting frame via the bushing. One end of the bushing is fixed to the lifting frame via a connecting limiting cap, and the other end of the variable-diameter rotating shaft is connected to a flipping servo motor fixed on one side of the lifting frame via a synchronous belt. A rotating arm and a clamping mechanism mounted on the rotating arm are fixed on the variable-diameter rotating shaft located on one side of the lifting frame.

[0008] In this invention, the clamping mechanism includes an adjusting plate with guide grooves on both sides. An angular sliding plate is installed on the end face of the guide groove of the adjusting plate. A limiting slider on one side of the angular sliding plate is installed and cooperates with the guide groove of the adjusting plate, so that the angular sliding plate moves linearly relative to the adjusting plate. High-temperature resistant grippers and hinged connecting rods are respectively provided at both ends of the angular sliding plate. The connecting rods are hinged to the clamping cylinder, and the middle part of the connecting rod is hinged to the adjusting plate by a pin. The clamping mechanism is symmetrically arranged at both ends of the rotating arm.

[0009] Furthermore, the rotating arm is a semi-circular shape.

[0010] In this invention, the air inlet pipe connected to the clamping cylinder is led out through the through holes on the upper and lower limit plates in the flipping mechanism and connected to the air supply source.

[0011] The beneficial effects of this utility model are: the lifting servo motor in the lifting mechanism drives the lead screw to rotate in both directions, controlling the lifting and lowering of the flipping mechanism installed on the lifting plate, and the clamping mechanism receives the washing machine glass observation window under high temperature transferred from the automatic film take-up machine; when the flipping mechanism descends, the clamping mechanism can place the washing machine glass observation window on the conveyor belt without damage, so that it can enter the next process flow.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] As shown in Figures 1 to 3, a flipping device for a washing machine glass observation window under high temperature conditions includes a bracket 1 and a lifting mechanism 2 mounted on the bracket 1. The lifting mechanism 2 is connected to a guide mechanism. A lifting frame 5 is mounted on the guide mechanism, and a flipping mechanism 6 is mounted on the upright lifting frame 5. A rotating arm 4 is mounted on the flipping mechanism 6, and clamping mechanisms 7 are symmetrically arranged at both ends of the rotating arm 4.

[0021] In the above description, the lifting mechanism 2 uses a lifting servo motor 8 connected to a lifting reduction motor 9. The lifting reduction motor 9 is mounted on the lower fixed guide plate 11 and is connected to a lead screw 3. The lead screw 3 is connected to the lead end of the lifting bearing 10 on the lower fixed guide plate 11, and is connected to a nut a on the lifting plate 13 of the guide mechanism to control the displacement of the lowering plate 13. Therefore, the lifting mechanism 2 controls the flipping mechanism 6 and the clamping mechanism 7 to rise or fall synchronously, realizing the lifting function of the mechanism. The rising function allows the device to receive the high-temperature washing machine glass observation window transferred from the automatic film take-up machine, and the falling function allows the device to place the observation device on the conveyor belt without damage.

[0022] In the above description, the guiding mechanism includes a lifting plate 13, on which four sliding guide posts 20 are fixedly mounted. These four guide posts 20 pass sequentially through corresponding guide holes (not shown in the figure) on the top guide plate 12 and the lower fixed guide plate 11 of the support. A nut a is provided on the lifting plate 13, which is connected to the lead screw of the lifting mechanism. The function of the guiding mechanism is to ensure the stability of the lifting mechanism 2 during the lifting process, guarantee the accuracy of the clamping point of the clamping mechanism 7 in gripping the glass observation window, and prevent gripping deviation leading to gripping failure.

[0023] In the above-described flipping mechanism 6, a variable-diameter rotating shaft 16 is included. A flipping bearing 17 mounted on the variable-diameter rotating shaft 16 is installed inside a bushing 15, which is then mounted on a lifting frame 5. One end of the bushing 15 is fixed to the lifting frame 5 via a connecting limiting cap 14. A synchronous belt 18 is installed on the other end of the variable-diameter rotating shaft 16 and connected to a flipping servo motor 19 fixed on one side of the lifting frame. A rotating arm 4 and clamping mechanisms 7 are fixed on the variable-diameter rotating shaft 16 located on one side of the lifting frame 5. The clamping mechanisms control the gripping and flipping of the glass observation window. The function of the flipping mechanism 6 is to grip the demolded glass observation window, flip it 180°, and place it on a conveyor belt for cooling and inspection. In this embodiment, the rotating arm 4 is a semi-circular body used for gripping and flipping the glass observation window. Therefore, the flipping mechanism 6 realizes the flipping function of the observation window; the clamping mechanism 7 clamps the glass observation window and is compatible with all washing machine glass observation windows currently on the market.

[0024] The clamping mechanism 7 described above includes an adjusting plate 23 with guide grooves b on both sides. A triangular sliding plate 24 is mounted on the end face of the guide groove b of the adjusting plate 23. A limiting slider c on one side of the triangular sliding plate 24 engages with the guide groove b of the adjusting plate 23, allowing the triangular sliding plate 24 to move linearly relative to the adjusting plate 23. High-temperature resistant grippers 25 and hinged connecting rods 22 are respectively provided at both ends of the triangular sliding plate 24. The connecting rods 22 are hinged to the clamping cylinder 21, and a pin d is hinged between the connecting rod 22 and the adjusting plate 23 at the middle. The clamping mechanism 7 is symmetrically arranged at both ends of the rotating arm 4. The clamping mechanism 7 can control the adjustment range of the opening size of the adjusting plate, and is compatible with clamping all irregularly shaped glass viewing windows of washing machines currently on the market.

[0025] The function of this invention is as follows: the lifting servo motor 8 in the lifting mechanism 2 drives the lead screw 3 to rotate in both directions, thereby controlling the lifting and lowering of the flipping mechanism 6. The clamping mechanism 7 receives the washing machine glass observation window 26 under high temperature conditions transferred from the automatic film take-up machine. When the flipping mechanism 6 flips 180 degrees and then descends, the clamping mechanism 7 can place the washing machine glass observation window 26 on the conveyor belt without damage, so that it can enter the next process flow.

[0026] The clamping cylinder 21 mentioned above is a high-temperature resistant cylinder that can withstand temperatures up to 150°C. The air inlet pipe connected to the clamping cylinder 21 is led out through the through holes on the upper and lower parts of the limiting cover 14 in the flipping mechanism and connected to the air supply source, so that the air inlet pipe will not twist during the flipping process.

[0027] Figure 4 shows the state of the glass observation window gripped by the flipping mechanism in Figure 1. After the glass observation window 26 is demolded, it falls onto the worktable. The lifting mechanism descends to the position of the glass observation window 26 and grips the neck position of the glass observation window 26 through the clamping mechanism 7. The gripping makes the concave surface of the glass observation window 26 face upward; the lifting mechanism rises to prepare for the flipping action.

[0028] Figure 5 shows the state after the glass observation window in Figure 4 is flipped 180 degrees by the flipping mechanism. The lifting mechanism rises, and the flipping mechanism 6 flips the glass observation window 26 with the opening facing upwards by 180 degrees, so that the concave position of the glass observation window 26 faces downwards. Then, the lifting mechanism descends and places the glass observation window 26 on the conveyor network for cooling and finished product qualification inspection.
