[0029] In order to describe the present invention in detail, first, the unloading device for the material tray provided by the present invention is specifically described below.

[0030] like Figure 1 As shown, the utility model provides a material unloading device for a material pallet, comprising a frame 1, a moving mechanism 2, a lifting mechanism 3, a suction mechanism 4 and a clamping mechanism 5. A transmission line 6 for transmitting a material pallet 7 is provided on the frame 1. After the preceding work is completed, the transmission line 6 transports the material pallet 7 to the unloading work station. The clamping mechanism 5 clamps the material pallet 7, and the suction mechanism 4 contacts and connects with the components in the material pallet 7 by means of negative pressure suction. The lifting mechanism 3 drives the clamping mechanism 5 and the suction mechanism 4 to move up or down. The entire lifting mechanism 3 is installed on the moving mechanism 2, which is arranged perpendicular to the transmission line 6. The moving mechanism 2 drives the lifting mechanism 3 to move so that the material pallet 7 and the components are removed from the transmission line 6. The entire lifting mechanism 3 cannot move relative to the transmission direction of the transmission line.

[0031] Among them, such as Figure 2 and Figure 3 As shown, the lifting mechanism 3 includes a first base plate 31 and a second base plate 32 slidably connected to the first base plate 31. The first base plate 31 is mounted on the moving mechanism 2, and the movement of the moving mechanism 2 drives the entire lifting mechanism 3 to move. A lifting power 33 and a slide rail are mounted on the first base plate 31, and a slider that matches the slide rail is provided on the back of the second base plate 32. A lead screw slider is used between the lifting power 33 and the second base plate 32, allowing the second base plate 32 and the first base plate 31 to slide relative to each other.

[0032] A first connecting plate 34 is connected to the second bottom plate 32. The first connecting plate 34 is perpendicularly disposed to the second bottom plate 32. To increase the strength of the first connecting plate 34, a triangular reinforcement plate 35 is disposed between the first connecting plate 34 and the second bottom plate 32. Of course, to reduce the weight of the entire lifting mechanism 3, weight-reducing holes may also be provided on the first bottom plate 31 and the reinforcement plate 35.

[0033] To position the lifting mechanism 3, a first sensor 36 and a second sensor 37 are installed along the lifting direction of the first base plate 31, and a sensing block 38 is installed on the second base plate 32. The sensing block 38 rises and falls with the second base plate 32. The first and second sensors 36 and 37 can be through-beam photoelectric sensors, which have a transmitter and a receiver. Normally, the receiver detects the signal emitted by the transmitter. When the sensing block 38 is located between the transmitter and the receiver, the signal is interrupted, indicating that the lifting mechanism 3 has reached its limit of ascent or descent.

[0034] The clamping mechanism 5 includes a clamping cylinder 51 and a clamping block 52 mounted on the output end of the clamping cylinder 51. In order to clamp the material tray 7, it must be clamped in at least two opposite directions. In this embodiment, the clamping blocks 52 on both sides are arranged on both sides along the transmission direction of the transmission line 6. That is, when the clamping mechanism 5 grabs the material tray, the clamping blocks 52 on both sides are located in the width direction of the transmission line 6. To reduce the number of clamping cylinders 51, in some embodiments, the clamping cylinder 51 adopts a double-headed cylinder, so that only one clamping cylinder is required. The fixed portion of the clamping cylinder 51 is mounted on the first connecting plate 34. One end of the double-headed cylinder's extended end is close to the first base plate 31, and the other end is away from the first base plate 31. That is, when the double-headed cylinder is extended, it is equivalent to extending along the width direction of the transmission line 6.

[0035] The clamping block 52 is positioned along the width of the conveyor line 6 primarily to optimize efficiency and safety during material handling. For longer products, if the clamping block 52 is installed longitudinally, at least two clamping cylinders 51 are required to separately control the clamping action at each end. This not only increases the complexity and cost of the entire system, but can also lead to inaccurate product positioning or unstable clamping due to slight differences in synchronization control at both ends. Conversely, positioning the clamping block 52 in the width direction allows for effective fixation using a single double-ended cylinder, simplifying the mechanical structure while ensuring excellent operational precision.

[0036] Secondly, given that multiple types and sizes of goods may be moving simultaneously on a production line, if the clamping block 52 were positioned in the direction of the conveyor line 6, it would likely collide with other moving items during the pick-and-place operation. This design flaw would not only potentially damage the goods but, more importantly, disrupt the normal production line process, causing unnecessary downtime and severely impacting overall production efficiency. By positioning the clamping block 52 perpendicular to the conveyor line 6, these potential obstacles are effectively avoided, ensuring that each step can be completed smoothly and unimpeded, providing a strong guarantee for continuous and efficient production activities.

[0037] Among them, such as Figure 4As shown, in order to grasp the material tray 7 more stably, two clamping blocks 52 are set on each side. The clamping block 52 includes a connecting section 521 and a clamping section 522. The clamping section 522 is arranged to intersect with the connecting section 521 to form an L shape. In order to make it easier for the clamping section 522 to contact and clamp with the material tray 7, the clamping section 522 is designed to be wedge-shaped. The width of the clamping section 522 on the side away from the connecting section 521 is smaller than the width on the side close to the connecting section 521. The cross-section of the wedge is trapezoidal. When the clamping section 522 contacts the material tray 7, as the depth increases, the contact area between the clamping block 52 and the material tray 7 gradually increases, which can provide a stronger clamping force, thereby effectively preventing the material tray 7 from being displaced or falling during movement.

[0038] In some embodiments, the clamping mechanism 4 includes a second connecting plate 41 and a plurality of suction cups 42 mounted on the second connecting plate 41. The second connecting plate 41 is connected to the first connecting plate 34 via vertical plates 43. Vertical plates 43 are mounted on both sides of the first connecting plate 34. The second connecting plate 41 does not affect the extension of the extended end of the clamping cylinder 51. Mounting holes 44 are formed in the first connecting plate 34. The suction cups 42 are fixed to the mounting holes 44 by bolts. The suction cups 42 and the clamping cylinder 51 are both connected to the air source via air pipes.

[0039] Multiple suction cups 42 can be provided on the second connecting plate 41 and arranged along the transmission direction of the transmission line 6. The mounting holes 44 for the suction cups 42 can also be configured in a strip shape, allowing for adjustable positions of the suction cups 42. Adjacent suction cups 42 can be positioned off-line along the transmission direction of the transmission line 6, resulting in more stable suction of components. The bottoms of the suction cups 42 can be shaped like a trumpet, providing greater grip when gripping components.

[0040] When the clamping block 52 grabs the material tray 7 and the parts are sucked by the suction cup 42 under negative pressure, in order to reduce the excessive force of the suction cup 42, which may cause the parts to be sucked up too high a height and cause damage to the parts, a third connecting plate 45 is provided on the side of the second connecting plate 41 away from the first old connecting plate, and a positioning block 46 is installed on the third connecting plate 45 to limit the parts.

[0041] In some embodiments, the moving mechanism 2 includes a moving power source 21 and a guide rail 22. The output end of the moving power source 21 is connected to a gear. A rack 23 is provided on the platform of the unloading device. The gear and rack 23 cooperate to enable the entire lifting mechanism 3 to move. The guide rail 22 is arranged parallel to the rack 23. Both the rack 23 and the guide rail 22 are arranged perpendicular to the transmission line 6. A moving plate 24 is mounted on the guide rail 22. The moving power source 21 is mounted on the moving plate 24. The lifting mechanism 3 is also mounted on the moving plate 24. A slider that mates with the guide rail 22 is provided at the bottom of the moving plate 24.

[0042] The mobile mechanism 2 is positioned perpendicular to the conveyor line 6. The unloading device also includes a recovery platform located to the side of the conveyor line 6. After the clamping block 52 secures the material tray 7, the mobile mechanism 2 moves the material tray 7 above the recovery platform. The clamping block 52 is released, and the material tray 7 falls onto the recovery platform. A stopper is also provided at the end of the conveyor line 6 along the conveyor line's direction of transport to limit the position of the material tray 7.

[0043] Working process: When the material tray 7 carrying the parts is transported via the conveyor line 6 to the unloading station, the material tray 7 is stopped by a block. The mobile mechanism 2 then drives the lifting mechanism 3 to move above the material tray 7. The lifting power 33 controls the lowering of the second base plate 32. Simultaneously, the clamping cylinder 51 is actuated, expanding the clamping blocks 52 on both sides, making them wider than the width of the material tray 7. Once the lifting mechanism 3 is lowered into position, the clamping cylinder 51 controls the retraction of the clamping blocks 52, clamping the material tray 7. Simultaneously, the suction cups 42, under the action of negative pressure, retain the parts within the material tray 7. The lifting mechanism 3 then rises, disengaging the material tray from the conveyor line 6. The mobile mechanism 2 then drives the lifting mechanism 3 to the recovery station. The lifting mechanism 3 then descends, and the clamping cylinder 51 again extends the clamping blocks 52 on both sides, disengaging the material tray 7. The material tray 7 then falls onto the recovery station. Lifting mechanism 3 rises, and suction cup 42 holds the component. Moving mechanism 2 again moves lifting mechanism 3 above the component's moving line. Lifting mechanism 3 descends, and suction cup 42 loses its suction, allowing the component to fall onto the moving line. The moving line and transmission line 6 are separate production lines, and they can be arranged parallel to or perpendicular to each other.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
