[0064] The adjustment block 12 is arranged at one end of each guide rod 11 close to the base 10 in the height direction. The adjustment block 12 is adjustably arranged on one side of the height direction of the base 10. The adjustment block 12 is suitable for adjusting the relative position of the guide rod 11 on the base 10.

[0065] Please note that, see Figure 1As shown, the adjustment block 12 is adjustably arranged on one side of the height direction of the base 10. By adjusting the relative position of the adjustment block 12 along the length direction and / or the width direction on the base 10, the guide rod 11 is driven to achieve position adjustment, so that blister boxes with different outer dimensions and specifications can be adapted, and blister boxes with different outer dimensions and specifications can be accurately positioned, which is convenient for the robot to accurately grasp.

[0066] In some embodiments, please combine Figure 2 and Figure 3 As shown, a plurality of first threaded holes 101 are provided on the base 10 at corresponding positions of each adjustment block 12, and the plurality of first threaded holes 101 can be arranged at intervals along the length direction and / or the width direction on the base 10;

[0067] The blister box positioning and adjusting assembly further comprises a first screw 13 , one end of which is connected to the adjusting block 12 , and the other end of which is suitable for being threadedly connected to any first threaded hole 101 .

[0068] In this embodiment, a plurality of first threaded holes 101 are opened at corresponding positions of each adjustment block 12 on the base 10, and the first screws 13 are selectively connected to the first threaded holes 101 to adjust the relative positions of the adjustment blocks 12 and the guide rods 11 on the adjustment blocks 12 on the base 10 along the length direction and / or the width direction, so that blister boxes with different outer dimensions and specifications can be adapted, and blister boxes with different outer dimensions and specifications can be accurately positioned, so as to facilitate accurate grasping by the robot.

[0069] In some embodiments, please combine Figure 3 and Figure 4 As shown, a strip hole 121 is provided on the adjustment block 12. The strip hole 121 is arranged along the length direction and / or the width direction relative to the base 10. The strip hole 121 is suitable for matching with the first screw 13.

[0070] When the first screw 13 and the first threaded hole 101 are tightened, the strip-shaped hole 121 is suitable for limiting the first screw 13 in the height direction;

[0071] When the first screw 13 and the first threaded hole 101 are loosened, the first screw 13 is suitable for moving along the strip hole 121 relative to the adjustment block 12 .

[0073] In this embodiment, by opening a strip hole 121 on the adjustment block 12 to cooperate with the first screw 13, the adjustment block 12 can be moved relative to the first screw 13 to more accurately adjust the relative position of the adjustment block 12 and the guide rod 11 on the adjustment block 12 on the base 10 along the length direction and / or width direction, so that it can adapt to blister boxes of different outer dimensions and specifications, and realize precise positioning of blister boxes of different outer dimensions and specifications, which is convenient for the robot to accurately grasp.

[0074] It should be noted that, in some embodiments, the relative position of the adjustment block 12 and the guide rod 11 on the adjustment block 12 along the length direction and / or width direction on the base 10 can be adjusted by selectively connecting the first screw 13 with the first threaded hole 101 and moving the adjustment block 12 relative to the first screw 13 through the strip hole 121. This can not only expand the position adjustment range of the adjustment block 12, but also improve the precision of the position adjustment of the adjustment block 12, so that it can adapt to blister boxes of different external dimensions and specifications, and can more accurately position blister boxes of different external dimensions and specifications, which is convenient for the robot to accurately grasp.

[0075] In some embodiments, see Figure 4 As shown, the adjustment block 12 is provided with a first positioning hole 122 along the height direction, and the first positioning hole 122 is suitable for socket connection with the guide rod 11;

[0077] In this embodiment, the first positioning hole 122 is opened on the adjustment block 12, and the first positioning hole 122 is connected to the guide rod 11 through a socket connection to achieve the positioning of the guide rod 11; the second screw 14 is threadedly connected to the second threaded hole 111 of the guide rod 11, so as to achieve the fixing of the guide rod 11, and at the same time, the detachable connection between the guide rod 11 and the adjustment block 12 is achieved, which is convenient for disassembly and maintenance.

[0078] In some embodiments, please combine Figure 2-Figure 4 As shown, a limiting groove 102 is further provided on the base 10 at a position corresponding to the adjustment block 12 , and the limiting groove 102 is suitable for limiting the adjustment block 12 .

[0079] In this embodiment, by opening a limit groove 102 on the base 10, when the position of the adjustment block 12 is adjusted, the first screw 13 can be at least partially threadedly connected to the first threaded hole 101 and in a loosened state, thereby limiting the adjustment block 12 in the length direction or the width direction through the limit groove 102, thereby facilitating rapid and accurate position adjustment of the adjustment block 12.

[0080] In some embodiments, please combine Figure 3 and Figure 4 As shown, a corresponding position of the adjusting block 12 on the base 10 is provided with an avoidance groove 103 , and the avoidance groove 103 is suitable for avoiding the guide rod 11 .

[0081] It should be noted that in order to avoid interference between the adjustment block 12 and the surface of the base 10, part of the adjustment block 12 can be set on the side of the base 10 away from the blister box in the height direction; by opening an avoidance groove 103 on the base 10, it is convenient for the guide rod 11 to pass through the avoidance groove 103 and connect with the adjustment block 12. At the same time, the avoidance groove 103 limits and guides the guide rod 11, so that the adjustment block 12 can be quickly and accurately adjusted in position.

[0082] According to an embodiment of the present utility model, on the other hand, an automatic lifting and feeding device is also provided, comprising:

[0083] As the above-mentioned blister box positioning adjustment component, and

[0084] Abutment 10;

[0085] A fixing frame 20, one end of which along the height direction is fixed relatively to the base 10;

[0086] The lifting frame 30 has one end close to the base 10 in the height direction and is slidably connected to the fixing frame 20. The lifting frame 30 slides in the height direction relative to the fixing frame 20, thereby carrying the blister box to be lifted and lowered in the height direction relative to the base 10;

[0087] The driving screw assembly 40 is fixedly arranged in the fixing frame 20 along the height direction. The driving screw assembly 40 is transmission-connected with the lifting frame 30. The driving screw assembly 40 is suitable for driving the lifting frame 30 to rise and fall along the height direction.

[0088] The motor 50 is transmission-connected to the driving screw assembly 40;

[0089] The position monitoring component 60 is fixedly arranged on a side of the base 10 away from the fixing frame 20 in the height direction. The position monitoring component 60 is electrically and / or communicatively connected to the motor 50. The position monitoring component 60 is suitable for controlling the motor 50 to stop when a blister box is detected.

[0090] In the related technology, the commonly used method of loading hardware is to manually implant it directly into the mold, but the efficiency is low and it is difficult to apply to mass production. The hardware is placed one by one in the grid of the blister box. The robot can put the hardware on the base of the implant fixture, and then the manipulator comes to absorb it and implant it into the mold. Because when the robot is loading, after the hardware of the previous blister box is used up, the hardware position of the next blister box is lower than the previous position, so it cannot be directly absorbed. The robot needs to adopt the stacking programming method. On the one hand, the specifications of the blister boxes must be uniform in height. On the other hand, the overall debugging is time-consuming. On the other hand, the number of blister boxes stacked each time needs to be fixed when the robot stacking programming loading method is adopted.

[0091] It should be noted that a multi-layer blister box can be arranged on the automatic lifting and loading device of the utility model, each layer of the multi-layer blister box is independent of each other and stacked in sequence along the height direction, and multiple hardware steel sheets are placed in each layer of the blister box. Whenever the motor 50 is started, the lifting frame 30, driven by the driving screw assembly 40, lifts the blister box in the height direction until the position monitoring assembly 60 detects the blister box on the uppermost layer. At this time, the position monitoring assembly 60 transmits a stop signal to the motor 50, causing the motor 50 to stop, and the lifting frame 30 stops rising and remains at the current height; the manipulator sucks the hardware steel sheets in the blister box on the uppermost layer and transfers them to the mold in sequence; when the hardware steel sheets in the blister box on the uppermost layer are transferred, the manipulator takes away the empty blister box on the uppermost layer. At this time, since the position monitoring assembly 60 cannot detect the blister box, the motor 50 is started again, and the lifting frame 30, driven by the driving screw assembly 40, lifts the blister box in the height direction until the position monitoring assembly 60 detects the blister box on the next layer again, and then the manipulator transfers and loads the material again; when all the blister boxes on the lifting frame 30 are transferred, the lifting frame 30 descends until it is reset to the original position.

[0092] Furthermore, one end of the fixing frame 20 along the height direction may be connected to the base 10 by bolts and / or screws.

[0093] The automatic lifting and loading device provided in this embodiment includes a base 10, a fixed frame 20, a lifting frame 30, a driving screw assembly 40, a motor 50 and a position monitoring assembly 60; the fixed frame 20 is arranged along the height direction, and the fixed frame 20 is relatively fixed to the base 10; the lifting frame 30 is arranged along the height direction, and the lifting frame 30 slides along the height direction relative to the fixed frame 20; the driving screw assembly 40 is connected to the lifting frame 30 in a transmission manner, and the driving screw assembly 40 is suitable for driving the lifting frame 30 to make reciprocating linear motion along the height direction under the drive of the motor 50, so that the lifting frame 30 carries The blister box is raised and lowered in the height direction relative to the base 10; the position monitoring component 60 is electrically and / or communicatively connected to the motor 50. Whenever the position monitoring component 60 detects the blister box located at the uppermost layer, the position monitoring component 60 transmits a stop signal to the motor 50, so that the motor 50 stops, and the lifting frame 30 stops rising and remains at the current height, so that the position of the hardware in the blister box is always maintained at the specified height required for the robot to suck, avoiding the restrictions on the specification height and stacking quantity of the blister box by the robot stacking programming, which is beneficial to saving debugging time and facilitating mass production.
