[0043] As shown in Figures 1-5 The present application relates to a tray 100 unloading device, which comprises a base 1, a tray rack 2, a tray placing plate 3, a lifting mechanism 4, an unloading tray 5, a pulling mechanism 6, and a robot 8. The base 1 is used to support various components of the entire device to ensure stable operation of the device. The tray rack 2 places the trays 100 in an upper and lower hierarchy, facilitating the stacking of multiple trays 100 and unloading when needed.

[0044] The tray placing plate 3 is arranged on the base 1 and is used to support and place the tray rack 2. It can be lifted in the vertical direction by the lifting mechanism 4 to adjust the position of the tray rack 2, so that the unloading tray 5 can accurately receive the unloaded trays 100. The lifting mechanism 4 is installed at the bottom of the tray placing plate 3 and can drive the tray placing plate 3 to move up and down, thereby achieving accurate positioning of the tray rack 2 and facilitating unloading of the trays 100.

[0045] The unloading tray 5 has a U-shaped structure and is arranged on one side of the tray placing plate 3. It is mainly used to receive and stabilize the trays 100. The pulling mechanism 6 is connected to the unloading tray 5 through a moving module 7 and is responsible for pulling the trays 100 from the tray rack 2 to the unloading tray 5. The specific structure of the pulling mechanism 6 includes a fixed plate 61, a limiting plate 62, a mounting plate 63, a pulling cylinder 64, and a pulling plate 65. The fixed plate 61 is connected to the unloading tray 5 through the moving module 7, and the limiting plate 62 is connected to the fixed plate 61 to limit the position of the trays 100 on the unloading tray 5 and prevent deviation. The mounting plate 63 is connected perpendicularly to the fixed plate 61 to support the pulling cylinder 64. One side of the pulling plate 65 is designed with a hook plate 66, which is arranged downward and maintains a gap with the right side of the limiting plate 62. The pulling cylinder 64 drives the pulling plate 65 to move up and down through extension and retraction to ensure that the hook plate 66 is inserted into the tray 100, thereby achieving pulling of the tray 100. The robot 8 is responsible for transporting the trays 100 placed on the unloading tray 5 to the next process, further improving the automation level of the device.

[0046] Specifically, the trays 100 are placed on the tray rack 2 layer by layer, the height position of the material placing tray 3 is adjusted by the lifting mechanism 4, so that the bottom of the uppermost tray 100 is slightly higher than the material unloading tray 5; the material pulling mechanism 6 is driven by the moving module 7 to move to the side of the tray rack 2, at this time, the side edge fence of the tray 100 is between the hook plate 66 and the right side of the limiting plate 62, the material pulling cylinder 64 drives the pulling plate 65 to move downward, so that the hook plate 66 is placed into the tray 100; the moving module 7 drives the material pulling mechanism 6 to move to the left side, the pulling plate 65 and the hook plate 66 pull the tray 100 to move to the material unloading tray 5 until reaching the specified position; the material pulling cylinder 64 drives the pulling plate 65 to move upward, the moving module 7 drives the material pulling mechanism 6 to continue to move to the left side until completely separated from the tray 100; the robot 8 moves the tray 100 to the next process; the lifting mechanism 4 lifts the material placing tray 3 upward, so that the bottom of the uppermost tray 100 is slightly higher than the material unloading tray 5, and the above-mentioned actions are continuously completed.

[0047] In the embodiment of the present application, the lifting mechanism 4 drives the material placing tray 3 to lift, the height of the material placing tray 3 is accurately controlled and adjusted, so that the tray 100 in the tray rack 2 can be accurately docked with the material unloading tray 5. Through the accurate control of the material pulling mechanism 6, it is ensured that the tray 100 does not deviate or tilt during the unloading process, so as to achieve the purpose of improving the unloading precision and stability of the tray 100, and further realize the high efficiency of the automatic unloading process of the tray 100, and solve the technical problems of unstable unloading, poor precision and frequent manual operation of the traditional tray 100 unloading device.

[0048] In the embodiment, the lifting mechanism 4 is a ball screw lifting machine, which is driven by a servo motor 41. The lifting mechanism 4 is connected with the bottom of the material placing tray 3 through a screw rod, the screw rod end penetrates through the base 1 to drive the tray to lift. The ball screw lifting machine has high transmission precision and low friction loss, can stably and efficiently drive the material placing tray 3 to move up and down, and ensure the accurate unloading of the tray 100.

[0049] Further, first guide shafts 9 are arranged at the bottom of the material placing tray 3 at four corner positions respectively, the first guide shafts 9 are slidingly connected in the first linear bearings 10, and the first linear bearings 10 are installed on the base 1. This structure design effectively ensures the stable operation of the material placing tray 3 during lifting, prevents the tray from tilting or unbalanced during lifting, and improves the operation precision and stability of the device.

[0050] To further ensure the stability of the unloading pallet 5, a baffle 11 is arranged on the side of the material arranging pallet 3 close to the unloading pallet 5. When the uppermost tray 100 is pulled to the unloading pallet 5, the tray rack 2 and other trays 100 on the tray rack 2 will not move to the left side due to the pulling force; the baffle 11 can prevent the tray rack 2 and the trays 100 on the tray rack 2 from deviating during the unloading process, and ensure that the trays 100 are always correctly positioned during the unloading process; at the same time, the displacement position of the material pulling mechanism 6 can be limited.

[0051] When the right side surface of the limiting plate 62 is in contact with the baffle 11, the side edge baffle of the tray 100 is between the hook plate 66 and the right side surface of the limiting plate 62.

[0052] In the embodiment, a jacking cylinder 12 is connected to the bottom of the base 1 below the unloading pallet 5. The telescopic end of the jacking cylinder 12 penetrates through the base 1 and is connected to the bottom of the unloading pallet 5, which is used to provide additional support force when the unloading pallet 5 is in the unloading position. Through precise telescopic adjustment, the jacking cylinder 12 can effectively pull the tray 100 from the tray rack 2 to the unloading pallet 5, and prevent unnecessary shaking or tilting of the tray 100, ensuring that the tray 100 is stably parked on the unloading pallet 5.

[0053] Further, the bottom corners of the unloading pallet 5 are also connected with second guide shafts 13 which are slidingly connected in second linear bearings 14. The second linear bearings 14 are also fixed on the base 1. The design of the guide shaft and the linear bearing further improves the stability of the unloading pallet 5, ensuring that the unloading pallet 5 can be smoothly lifted when the cylinder is in action, avoiding the problems of deviation or jam caused by the movement of the pallet.

[0054] In the embodiment, in order to facilitate the unloading of the tray 100, guide plates 15 are connected to the front and rear sides of the unloading pallet 5. The design of the guide plates 15 enables the tray 100 unloaded from the tray rack 2 to smoothly slide onto the unloading pallet 5, and prevents the tray 100 from falling or deviating during the unloading process. The function of the guide plate 15 is to guide the tray 100 to smoothly enter the receiving area of the unloading pallet 5, avoiding the situation of jamming or irregular placement of the tray 100 during the unloading process.

[0055] In the embodiment, the material pulling mechanism 6 is connected with the unloading pallet 5 through a moving module 7, which is responsible for pulling the tray 100 from the tray rack 2 to the unloading pallet 5. The moving module 7 includes a rodless cylinder 71, parallelly arranged slide rails 72, and sliding blocks 73 slidingly connected on the slide rails 72. The function of the rodless cylinder 71 is to provide pulling force to drive the sliding blocks 73 to slide on the slide rails 72, thereby completing the pulling action of the tray 100. The advantage of this design is that it can achieve efficient and stable movement, avoiding the friction and resistance problems in the traditional material pulling mechanism 6, and improving the accuracy and efficiency of the entire pulling process.

[0056] The limiting plate 62 in the pulling mechanism 6 is provided with a positioning pin 67, and the bottom of the pulling plate 65 is provided with a limiting hole 68 above the positioning pin 67. Through this design, the positioning pin 67 can be accurately inserted into the limiting hole 68, limiting the up-and-down movement range of the pulling plate 65, preventing the pulling plate 65 from moving or deviating excessively, and ensuring that the tray 100 can be accurately pulled from the tray rack 2 to the unloading tray 5.

[0057] Further, the base 1 is provided with a bumper 16 below the tray 3, reducing the collision and friction between the tray 3 and the base 1 during lifting.

[0058] The working principle of the device is as follows: the tray racks 2 are arranged in layers on the base 1, and each layer of the tray racks 2 can accommodate a tray 100. When the tray 100 needs to be unloaded, the first lifting mechanism 4 drives the tray 3 to lift, so that the tray 100 on the tray rack 2 is positioned at the appropriate height of the unloading tray 5; the pulling mechanism 6 is driven by the moving module 7 to move stably to the side of the tray rack 2. At this time, the side fence of the tray 100 is located between the hook plate 66 and the right side of the limiting plate 62, preparing for the pulling operation of the tray 100; the pulling cylinder 64 starts to work, driving the pulling plate 65 to move downward, so that the hook plate 66 is smoothly put into the tray 100, and the hook plate 66 contacts and fixes the tray 100; the moving module 7 drives the pulling mechanism 6 to translate to the left side, and the pulling plate 65 and the hook plate 66 jointly act on the tray 100 to pull it from the tray rack 2, and the tray 100 is guided by the pulling mechanism 6 and the guide plate 15 to move to the unloading tray 5 until the tray 100 reaches the designated position; the pulling cylinder 64 drives the pulling plate 65 to move upward, gradually releasing the tray 100, and the moving module 7 continues to drive the pulling mechanism 6 to move to the left until the pulling mechanism 6 is completely separated from the tray 100; once the tray 100 is stably placed on the unloading tray 5, the robot 8 immediately starts to work, and the robot 8 accurately carries the tray 100 to the next process through the clamping jaw or suction cup, etc., completing the transfer of the tray 100; the lifting mechanism 4 starts to work, lifting the tray 3 upward, adjusting the bottom of the uppermost tray 100 to be slightly higher than the height of the unloading tray 5, preparing for the next unloading operation.

[0059] From the above description, it can be seen that the application achieves the following technical effects: In the embodiment of the application, the material placing support plate 3 is driven to lift by the lifting mechanism 4, the height of the material placing support plate 3 is accurately controlled and adjusted, so that the tray 100 in the tray rack 2 can be accurately docked with the unloading support plate 5. Through the accurate control of the material pulling mechanism 6, it is ensured that the tray 100 does not deviate or tilt during the unloading process, thereby achieving the purpose of improving the unloading precision and stability of the tray 100, and further realizing the high efficiency of the automatic unloading process of the tray 100, and solving the technical problems of unstable unloading, poor precision and frequent manual operation of the tray 100 in the traditional tray 100 unloading device.

[0060] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application.
