Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Please see Figures 1-5The SMT electronic tray automatic unloading and palletizing equipment of this embodiment includes a frame 1. A tray inlet 2 is provided at the bottom of the side wall of the frame 1. An outlet 3 is provided at the bottom of the adjacent side wall of the tray inlet 2. A pallet inlet 4 is provided on the side wall of the frame 1 away from the outlet 3. A first flow line 5 is horizontally arranged inside the tray inlet 2 for feeding and conveying the tray. A second flow line 6 is horizontally arranged between the pallet inlet 4 and the outlet 3 for conveying the pallet 7. The top of the first flow line 5 is provided with several trays 7. A stacking mechanism 8 is provided on the side of the first flow line 5 away from the tray inlet 2 for stacking the trays. A conveying mechanism 9 is provided on the top of the second flow line 6 for conveying the stacked trays. The stacking mechanism 8 includes a first linear module 801, which is horizontally arranged on the top of the first flow line 5. The moving platform of the first linear module 801 is fixedly connected to a first movable frame 802. The side wall of the first movable frame 802 is vertically provided with... The first lifting module 803 has a lifting platform fixedly connected to a lifting frame 804. An internal support mechanism 805 is provided at the bottom of the lifting frame 804, and several limiting plates 806 are provided at the bottom of the internal support mechanism 805. The bottom of the first streamline 5 has a first mounting frame 807, and a telescopic cylinder 808 is horizontally fixedly connected to the side wall of the first mounting frame 807. A stop block 809 is fixedly connected to the piston rod of the telescopic cylinder 808, and a stop block 809 is provided on the side of the stop block 809 away from the telescopic cylinder 808. The first mounting frame 807 has an arc-shaped surface; a second mounting frame 810 is provided on the side away from the material tray inlet 2. A rotary cylinder 811 is fixedly connected to the side wall of the second mounting frame 810. A feeding frame 812 is fixedly connected to the rotating table of the rotary cylinder 811. The feeding frame 812 is arranged in an "L" shape. A pair of limiting rods 813 are vertically fixedly connected to the bottom edge of the feeding frame 812 away from the stop block 809. A material storage cavity is formed between the stop block 809, the feeding frame 812 and the limiting rods 813.When the material tray is discharged, it flows into the interior of the frame 1 along the first flow line 5 and the material tray inlet 2. When it moves to the bottom of the inner support mechanism 805, it stops moving. At this time, the first lifting module 803 drives the lifting frame 804 and the inner support mechanism 805 to move downward, so that the support rod at the bottom of the inner support mechanism 805 is inserted into the through hole in the center of the material tray until the limit plate 806 abuts against the top of the material tray. Then the inner support mechanism 805 drives the support rod to open and fix the material tray. Then the first lifting mechanism 803 resets, thereby driving the inner support mechanism 805 to clamp the material tray. At this time, the unloading rack 812 is in a vertical state, and the telescopic cylinder 808 drives the stop block 809 to extend, so that the stop block 809 and the unloading rack 812 form a stacking cavity. Then the first linear module 801 drives the material tray to move to the top of the stacking cavity, and then the first lifting mechanism 803 drives the inner support mechanism 805 to move downward to place the material tray in the stacking cavity. The above process is repeated. The process involves automatically stacking and palletizing material trays. When the material trays in the stacking chamber are full, the telescopic cylinder 808 drives the stop block 809 to reset, and then the rotary cylinder 811 drives the unloading rack 812 to rotate towards the side with the limit rod 813 until it stops at the horizontally inclined upward transport position. Finally, the stacked material trays are transported by the transport mechanism 9. During transport, the empty pallet 7 moves along the second flow line 6 along the pallet inlet 4 to the bottom of the transport mechanism 9. The transport mechanism 9 then places the material tray horizontally inside the pallet 7. Finally, the full-loaded pallet 7 flows out along the second flow line 6 along the outlet 3. Through the above steps, fully automatic stacking, transporting, and unloading of material trays can be achieved, thereby effectively improving the automation level of the equipment and the conveying efficiency of the material trays. At the same time, the stacked materials can be horizontally reversed, making it easier to transport them to the pallet 7 for storage and transport, thereby effectively improving the space utilization of the equipment.
[0029] The bottom edge of the feeding rack 812 facing the stop block 809 has a slot 814. The slot 814 facilitates the clamping plate 905 to clamp the bottom of the material tray.
[0030] Please see Figure 6The conveying mechanism 9 includes a second linear module 901, a second movable frame 902 is fixedly connected to the moving platform of the second linear module 901, and a second lifting module 903 is vertically arranged on the side wall of the second movable frame 902; a first clamping cylinder 904 is fixedly connected to the lifting platform of the second lifting module 903, and a pair of clamping plates 905 are symmetrically fixedly connected to the piston rods on both sides of the first clamping cylinder 904. During transport, the second linear module 901 drives a pair of clamping plates 905 to move to the top of the unloading rack 812. At this time, the second lifting module 903 drives the first clamping cylinder 904 and the pair of clamping plates 905 to move downward until the clamping plates 905 are respectively located on both sides of the unloading rack 812. Then, the first clamping cylinder 904 drives the clamping plates 905 on both sides to clamp the materials stacked in the unloading rack 812. At this time, the second lifting module 903 resets, and the second linear module 901 drives the clamping plates 905 to move to the top of the empty pallet 7. Then, the second lifting module 903 drives the first clamping cylinder 904 to move downward to the unloading station. At this time, the first clamping cylinder 904 drives the clamping plates 905 to open, placing the material tray horizontally inside the pallet 7.
[0031] Please see Figure 7 A fixed frame 10 is provided at the bottom of the second flow line 6. A second clamping cylinder 11 is fixedly connected to the top of the fixed frame 10. A pair of grippers 12 are symmetrically fixedly connected to the piston rods on both sides of the second clamping cylinder 11. A clamping block 13 is fixedly connected to the top of the opposing sidewall of the grippers 12. During the material tray handling process, when the empty pallet 7 moves between the pair of clamping blocks 13, the second clamping cylinder 11 drives the grippers 12 on both sides to close, so that the clamping blocks 13 move towards each other until the clamping blocks 13 abut against the sidewall of the pallet 7, thereby limiting and fixing the pallet 7 during handling and preventing it from tilting when receiving materials.
[0032] The gripper 12 is located on the underside of the clamping plate 905.
[0033] The bottom of the pallet 7 is arc-shaped, and several arc-shaped grooves 701 are formed on the inner bottom side of the pallet 7. By providing arc-shaped grooves 701, the material trays inside the pallet 7 can be limited to prevent them from tipping over during transportation.
[0034] Working principle: When the material tray is discharged, it flows into the interior of the frame 1 along the first flow line 5 and the material tray inlet 2. When it moves to the bottom of the inner support mechanism 805, it stops moving. At this time, the first lifting module 803 drives the lifting frame 804 and the inner support mechanism 805 to move downward, so that the support rod at the bottom of the inner support mechanism 805 is inserted into the through hole in the center of the material tray until the limit plate 806 abuts against the top of the material tray. Then the inner support mechanism 805 drives the support rod to open and fix the material tray. Then the first lifting mechanism 803 resets, thereby driving the inner support mechanism 805 to clamp the material tray. At this time, the unloading rack 812 is in a vertical state, and the telescopic cylinder 808 drives the stop block 809 to extend, so that the stop block 809 and the unloading rack 812 form a material stacking cavity. Then The first linear module 801 drives the pallet to the top of the stacking cavity, and then the first lifting mechanism 803 drives the inner support mechanism 805 to move downwards to place the pallet in the stacking cavity; repeating the above steps, the pallets are automatically stacked; when the pallets in the stacking cavity are full, the telescopic cylinder 808 drives the stop block 809 to reset, and then the rotary cylinder 811 drives the unloading rack 812 to rotate to the side with the limit rod 813 until it stops at the horizontally inclined upward transport position; finally, the transport mechanism 9 transports the stacked pallets. During transport, the empty pallet 7 moves along the second flow line 6 along the pallet inlet 4 to the bottom of the transport mechanism 9, and the transport mechanism 9 places the pallet horizontally inside the pallet 7; during transport, The second linear module 901 drives a pair of clamping plates 905 to move to the top of the feeding rack 812. At this time, the second lifting module 903 drives the first clamping cylinder 904 and the pair of clamping plates 905 to move downward until the clamping plates 905 are respectively located on both sides of the feeding rack 812. Then, the first clamping cylinder 904 drives the clamping plates 905 on both sides to clamp the materials stacked in the feeding rack 812. At this time, the second lifting module 903 resets, and the second linear module 901 drives the clamping plates 905 to move to the top of the empty tray 7. Then, the second lifting module 903 drives the first clamping cylinder 904 to move downward to the feeding station. At this time, the first clamping cylinder 904 drives the clamping plates 905 to open, placing the material tray horizontally inside the tray 7. During the material tray handling process, when an empty pallet 7 moves between a pair of clamping blocks 13, the second clamping cylinder 11 drives the jaws 12 on both sides to close, causing the clamping blocks 13 to move towards each other until they abut against the side wall of the pallet 7. This limits and fixes the pallet 7 during handling, preventing it from tilting when receiving materials. After the material tray is placed into the pallet 7, the fully loaded pallet 7 flows out along the discharge port 3 along the second flow line 6. Through the above steps, fully automatic pallet stacking, handling, and discharge can be achieved, thereby effectively improving the automation level of the equipment and increasing the conveying efficiency of the material tray. At the same time, the stacked materials can be horizontally reversed, making it easier to transport them to the pallet 7 for storage and conveying, thereby effectively improving the space utilization of the equipment.
