The material supply table 1 includes at least one material area 8 for stacking material sheets 9. In this embodiment, two areas are shown in the attached drawings for easy alternation. This allows the equipment to automatically adjust to use the other side after the worker has used up one side, and the worker can replace the material on the used side. The robotic arm 2 includes a feeding suction cup 21 and a discharging suction cup 22 for adsorbing the material sheets 9, and also includes a material distribution clamp 3 for adsorbing the material sheets 9 one by one from the material area 8 and supplying them to the robotic arm 2. The material distribution clamp 3 serves to rotate the material sheets 9 between the material area 8, the alignment table 42, and the robotic arm 2. The movement trajectory is vertical and horizontal, based on the principle of the horizontal moving axis 32 and the vertical lifting seat 11 as described below. The material distribution clamp 3 adsorbs and moves the raw material sheet 9. During this process, some dust and other debris on the raw material sheet 9 can also fall off. The raw material supply table 1 in this embodiment is also equipped with a correction and centering mechanism 4. The raw material sheet 9 moves from the raw material area 8 to the middle of the robotic arm 2 through the material distribution clamp 3 and must pass through the correction and centering mechanism 4 for correction and correction. The correction and centering mechanism 4 can correct the raw material sheet 9 before it reaches the robotic arm 2, ensuring that when it is transferred to the robotic arm 2, the material adsorbed by the loading suction cup 21 of the robotic arm 2 remains in a consistent position.

[0018] As a further feature of the above solution, the width of the clamping arm 33 of the material dispensing fixture 3 is smaller than the inner opening 24 of the mounting frame 23 of the U-shaped robotic arm 2. The clamping arm 33 and the inner opening 24 of the mounting frame 23 are offset in the vertical direction without interference. The inner opening 24 is designed to ensure that when the raw material sheet 9 is transferred from the clamping arm 33 of the material dispensing fixture 3 to the robotic arm 2 during the final stage of delivery, the vertical descent of the clamping arm 33 will not hit the mounting frame 23, so that the two can smoothly complete the handover of the raw material sheet 9.

[0019] As a further arrangement of the above-mentioned scheme, the action of the material distribution clamp 3 includes adsorbing the raw material sheet 9 from the raw material area 8 and placing it on the deviation correction and centering mechanism 4, adsorbing the corrected raw material sheet 9 from the deviation correction and centering mechanism 4 and moving it to one side, and then adsorbing it away by the mechanical arm 2 which is previously stopped at the side.

[0020] As a further arrangement of the above-mentioned scheme, the deviation correction and centering mechanism 4 includes a longitudinal centering clamp arm 41, a material sensor, and a deviation correction platform 42, and a transverse sensor 35 is further arranged on one side of the material distribution clamp 3, the material sensor is used to sense the raw material sheet 9 on the deviation correction platform 42 and feed back a signal to start the longitudinal centering clamp arm 41 to correct the position of the raw material sheet 9, and the transverse sensor 35 is used to detect the edges of the raw material sheet 9, and the material distribution clamp 3 adsorbs the raw material sheet 9 according to the edge position and aligns the middle part.

[0021] As a further arrangement of the above-mentioned scheme, the raw material area 8 is provided with two raw material areas 8, the material distribution clamp 3 adsorbs the raw material from the raw material areas 8 located on both sides of the deviation correction and centering mechanism 4 according to the sensor detection, and the deviation correction platform 42 is further provided with an electrostatic elimination ion wind rod 44 for electrostatic elimination of the raw material sheet 9, and in the scheme of the embodiment, a plurality of groups of sensors are arranged, and the horizontal movement, vertical movement, swing of the mechanical arm 2 and the like are all sensed and fed back by the arranged sensors.

[0022] As a further arrangement of the above-mentioned scheme, the material distribution clamp 3 further includes a horizontal movement shaft 32 for horizontal movement of the clamp arm 33, and a vertical lifting seat 11 for lifting of the horizontal movement shaft 32, and the horizontal movement shaft 32 and the vertical lifting seat 11 are both provided with independent driving units.

[0023] Reference Figs. 1-3 The luggage blister machine raw material delivery device of the utility model, the delivery device of the embodiment further has a deviation correction and centering design, can place the raw material sheets 9 from the raw material areas 8 of the stacking area one by one into the deviation correction and centering mechanism 4 for centering, deviation correction and correction, and then move to the loading suction cup 21 of the mechanical arm 2, so as to facilitate the feeding of the mechanical arm 2.

[0024] As Figs. 1-3 The working process principle steps of the delivery device of the embodiment are as follows:

[0025] ①, during the equipment operation process, the material distribution clamp 3 is started, the clamp arm 33 is moved to the raw material area 8, and the suction cup part 31 adsorbs the uppermost raw material sheet 9 of the raw material area 8 after approaching the raw material sheet 9;

[0026] ② Subsequently, the horizontal movable shaft 32 of the material distribution fixture 3, along with the fixture arm 33, adsorbs the raw material sheet 9 and first rises along the track of the vertical lifting seat 11. After rising to the predetermined height, i.e., after the height is higher than the correction table 42, the horizontal movable shaft 32 remains stationary in the height direction, and the fixture arm 33 moves along the horizontal movable shaft 32 to directly above the correction table 42 and then stops.

[0027] ③ When the clamp arm 33 carries the raw material sheet 9 to the top of the correction table 42, the suction cup 31 releases its adsorption, and the raw material sheet 9 falls on the correction table 42. After the material sensor detects this, the longitudinal centering clamp arm 41 is activated, so that the position of the raw material sheet 9 is corrected by the push of the longitudinal centering clamp arm 41.

[0028] ④ At this time, while releasing the raw material sheet 9, the material distribution clamp 3 moves horizontally and left and right relative to the raw material sheet 9 based on the horizontal movable axis 32. The horizontal sensor 35 (photoelectric switch) set on one side of the clamp arm 33 detects and starts. When it moves to one edge of the raw material sheet 9, it records the position and moves in the opposite direction until it reaches the other edge. By obtaining the distance between the two edges through the left and right translation, the equipment calculates the deviation value of the left and right position of the raw material sheet 9, and obtains the middle position based on the deviation value. The clamp arm 33 of the material distribution clamp 3, with the suction cup 31, stops horizontally at the center position of the raw material sheet 9.

[0029] ⑤ Then, the clamp arm 33 lowers with the suction cup 31 (along the vertical lifting seat 11 track, which is in principle open) and adheres to the raw material sheet 9, then lifts it back to its original height and moves laterally.

[0030] ⑥ When the suction cup 31 holds the corrected raw material sheet 9, the mounting frame 23 of the robotic arm 2, with the loading suction cup 21 and the unloading suction cup 22, is located on one side of the correction table 42 (at this time, the position of the mounting frame 23 is preset and fixed, and its horizontal height can be kept at the same level as the correction table 42, so as to ensure that the raw material sheet 9 will not touch the mounting frame 23 and the loading suction cup 21 on it when the clamping arm 33 moves horizontally).

[0031] ⑦ The clamp arm 33, carrying the suction cup 31, adsorbs the raw material sheet 9 and moves horizontally. At this time, the direction of movement is to the other side of the position where the mounting frame 23 stops. After the raw material sheet 9 completely leaves the correction table 42, it turns back and moves to the top of one side of the mounting frame 23. During this horizontal turning back movement, the anti-static ion air bar 44 starts working simultaneously to clean the raw material sheet 9.

[0032] 8. The final horizontal moving position of the clamp arm 33 is aligned with the inner opening 24 of the mounting rack 23, and the raw material sheet 9 is located at the preset position above the mounting rack 23, at this time, the clamp arm 33 is located at the opening side of the inner opening 24 (so that it will not be touched by the mounting rack 23 during the falling process), then the clamp arm 33 above the mounting rack 23 vertically falls (at this time, the raw material sheet 9 adsorbed by the suction cup 31 is also very close to the upper feeding suction cup 21, and the adsorption of the suction cup 31 can be directly closed and naturally dropped), during the falling process, the raw material sheet 9 contacts and is adsorbed by the upper feeding suction cup 21 on the mounting rack 23, so that the raw material sheet 9 is successfully transferred to the mechanical arm 2, as described above, at this time, the position of the raw material sheet 8 on the mechanical arm 2 is certainly good after the correction and centering, based on the corrected preset position, facilitating the next processing;

[0033] 8. After the raw material sheet 9 is transferred to the mechanical arm 2, the clamp arm 33 moves away along the feeding path and enters the process cycle of adsorbing the next raw material from the other side of the raw material stack 8, and the mechanical arm 2 normally feeds the equipment in the one-side work station for vacuum forming processing.

[0034] It is worth noting that as described above, the vertical lifting seat 11 and the horizontal moving shaft 32 of the embodiment are both provided with a driving unit, and the driving unit is independently provided and can be driven by various ways such as pneumatic, electric, etc., and is driven by a lead screw, etc., to realize straight line movement.

[0035] As further described above, the raw material area 8 of the embodiment is provided with at least one group, such as two groups as shown, and the purpose and implementation scheme of the setting can be that the clamp arm 33 alternately adsorbs the material, or that the material is adsorbed on one side, and the sensor detects the shortage of material and changes to the other side, facilitating the replacement of the material in the raw material area 8 by the staff.

[0036] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the present application scheme and its equivalent technology, the present application also intends to include these modifications and variations.
