DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The present embodiment discloses an elevator hall door loading and unloading flipping mechanism, which is used for the automated circulation of elevator hall door processing and is applicable to the production line of elevator hall doors, so as to facilitate the adsorption and flipping of elevator hall doors and improve the convenience and efficiency of operation and processing.

[0023] Reference Figure 1-Figure 3 As shown, the elevator hall door loading and unloading flipping mechanism includes a base, a rotating shaft 4, a rotating driver 8, a swing arm 5, a flip frame 6 and a plurality of suction cups 7. Among them, the base is used for support, and the base is divided into two halves, namely, a base 1 and a base 2 2. The rotating shaft 4 is installed on the base, and the base 1 1 and the base 2 2 are both installed with a bearing seat 3. The rotating shaft 4 is installed on the rotating shaft 4 through a bearing, so that the rotating shaft 4 can be rotatably installed on the base. The rotating shaft 4 is arranged in a roughly horizontal state.

[0024] The rotary driver 8 is installed on the base 1. The rotary driver 8 is a three-phase asynchronous motor with a rotary output end. The output end of the rotary driver 8 is coaxially connected to the rotating shaft 4 and can drive the rotating shaft 4 to rotate. At least two swing arms 5 are fixedly connected to the middle section of the rotating shaft 4, and the flip frame 6 is fixedly connected to the swing arms 5. A plurality of suction cups 7 are fixedly installed on the lower side of the flip frame 6, and the elevator hall door can be adsorbed by the suction cups 7. The plurality of suction cups 7 adsorb the elevator hall door together, thereby adsorbing the elevator hall door and completing the flip operation.

[0025] During the rotation of the shaft 4, the shaft 4, the swing arm 5, the flip frame 6 and the suction cup 7 will rotate together, and the workpiece of the elevator hall door can be flipped. During the rotation, the swing arm 5 has a first position and a second position, and the swing arm 5 can be rotated and adjusted between the first position and the second position. At the first position, the swing arm 5 is roughly in a horizontally extended shape. Figure 1-Figure 3 In the embodiment, the swing arm 5 is located at the first position. At the second position, the swing arm 5 is tilted upward. Generally speaking, the rotation stroke of the swing arm 5 is 90°.

[0026] Reference Figure 1 , Figure 2 As shown, the suction cup 7 is mounted on the flip frame 6 through a connecting rod 71, one end of the connecting rod 71 is mounted on the flip frame 6, and the suction cup 7 is mounted on the other end of the connecting rod 71, so that there is a certain distance between the suction cup 7 and the flip frame 6, forming a certain space. When the swing arm 5 is in the first position, the connecting rod 71 is located at the lower side of the flip frame 6, the upper end of the connecting rod 71 is fixedly connected to the flip frame 6, and the suction cup 7 is located at the lower end of the connecting rod 71, so that the suction cup 7 can be fixed at the corresponding position of the flip frame 6.

[0027] Each suction cup 7 has a downward suction surface 72. When the swing arm 5 rotates to the first position, each suction surface 72 faces downward and is located in the same plane. Through the suction surfaces 72 of each suction cup 7, the elevator hall door can be sucked together to fix the elevator hall door stably. Then, during the rotation of the swing arm 5, the swing arm 5 will swing upward. Figure 2 , the swing arm 5 will swing in the counterclockwise direction, and the elevator hall door will rotate accordingly, so that the elevator hall door can be realized, and the swing amplitude is about 90°. After the elevator hall door is turned over, the side originally facing downward will face the operator, thereby facilitating the user to perform processing operations.

[0028] Reference Figure 2 As shown, the swing arm 5 includes an inclined section 1 51 and an inclined section 2 52, and the inclined section 1 51 and the inclined section 2 52 are fixedly connected to form an obtuse-angled inclined structure. One end of the inclined section 1 51 is fixedly connected to the rotating shaft 4, and the other end of the inclined section 1 51 is connected to the end of the inclined section 2 52. The other end of the inclined section 2 52 will extend toward the outside of the rotating shaft 4, and the flip frame 6 can be fixedly installed at the inclined section 2 52. The ends of the inclined sections 1 51 and 2 52 connected to each other will be tilted in the direction away from the flip frame 6.

[0029] Reference Figure 1 , Figure 3 As shown, a positioning block 11 is fixedly connected to the outer periphery of the rotating shaft 4, and the positioning block 11 is located at one end of the rotating shaft 4 close to the base 1. The base is equipped with two groups of buffer mechanisms, and the two groups of buffer mechanisms are respectively adapted to the positioning block 11. During the rotation of the rotating shaft 4, the positioning position will swing within a certain angle range. When the rotating shaft 4 rotates to the first position, the positioning block 11 will be blocked by the first group of buffer mechanisms. When the rotating shaft 4 rotates to the second position, the positioning block 11 will be blocked by the second group of buffer mechanisms. The positioning block 11 will achieve position adjustment within the range of the two groups of buffer mechanisms.

[0030] Specifically, the buffer mechanism includes a buffer seat 9 and a buffer 10. The buffer seat 9 is fixedly mounted on the base to form two supporting points on the base 1. The buffer 10 is mounted on the buffer seat 9. The buffer 10 can be a hydraulic buffer 10. The hydraulic buffer 10 can resist the swing arm 5, thereby achieving the function of buffer support and avoiding hard collision between the swing arm 5 and the base and the frame.

[0031] Two proximity switches 12 are also installed on the base 1. The installation positions of the two proximity switches 12 correspond to the positions of the two groups of buffer mechanisms, and the proximity switches 12 can sense each other with the positioning block 11. When the rotating shaft 4 and the swing arm 5 rotate to the first position, the positioning block 11 will rotate to the vicinity of the first proximity switch 12, and the positioning block 11 will sense each other with the first proximity switch 12; when the rotating shaft 4 and the swing arm 5 rotate to the second position, the positioning block 11 will rotate to the vicinity of the second proximity switch 12, and the positioning block 11 will sense each other with the second proximity switch 12. Through the two proximity switches 12, the detection of two positions can be realized, and two different sensing signals can be triggered at two different positions.

[0032] Reference Figure 3 As shown, the flip frame 6 is a frame-like structure, including two support rods 1 61 and two support rods 2 62. The support rod 1 61 is arranged parallel to the rotating shaft 4, and the two support rods 1 61 are fixedly connected to the swing arm 5. The support rod 2 62 is fixedly connected between the two support rods 1 61, and the frame structure is roughly a quadrilateral. The frame-like structure can be adapted to the size of the elevator hall door to ensure the strength performance of the entire flip frame 6.

[0033] The support rod 1 61 is arranged in parallel with the rotating shaft 4, and a plurality of suction cups 7 are installed at the lower part of each support rod 1 61, and the suction cups 7 are distributed along the length direction of the support rod 1 61. Two groups of suction cups 7 are formed at the lower part of the two support rods 1 61, which can absorb and grasp the elevator hall door, and then drive the elevator hall door to achieve flip adjustment.

[0034] The elevator hall door loading and unloading flipping mechanism is installed on the elevator hall door production line as a part of the production line and cooperates with the robot. When the production line is started, the elevator hall door workpiece is transported to the bottom of the flipping mechanism through the assembly line. The sensor detects that an object is approaching and immediately sends a signal to the PLC. The PLC converts the signal and sends it to the rotary driver 8. Then the rotary driver 8 starts to act, and the rotary driver 8 drives the rotating shaft 4 to start rotating. The swing arm 5, the flip frame 6, the suction cup 7 and other components follow the rotation. When the device rotates to the first position, the positioning block 11 and the buffer mechanism buffer each other for positioning. At the same time, the proximity switch 12 and the positioning block 11 sense each other, and sense that the device rotates to the first position. Then, the suction cup 7 starts to absorb the elevator hall door workpiece to complete the grabbing, and then the rotary driver 8 rotates in the opposite direction by about 90°, and the positioning block 11 and another set of buffer mechanisms buffer each other for positioning. At the same time, the positioning block 11 and another proximity switch 12 sense each other, and sense that the device rotates to the second position, and the flipping of the elevator hall door workpiece is completed.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
