[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1 As shown, in one embodiment of this utility model, a pallet positioning component 2 is disclosed, which is disposed at the loading / unloading station 13 of the conveying device 1. The conveying device 1 includes a first drive belt 11 and a second drive belt 12 in parallel, with a clearance space between the first drive belt 11 and the second drive belt 12. The first drive belt 11 and the second drive belt 12 are used to convey pallets, including...

[0028] substrate 21;

[0029] Multiple buffers are disposed on the substrate 21;

[0030] A lifting mechanism is disposed on the base plate 21. The lifting mechanism includes a support plate 22 and a first driver 221 for driving the support plate 22 to lift. The support plate 22 is disposed between the two transmission belts. The buffer is disposed between the base plate 21 and the support plate 22.

[0031] A positioning mechanism is disposed on the substrate 21. The positioning mechanism includes two clamping members arranged opposite each other and a second driver 238 for driving the two clamping members to move closer or further apart. The two clamping members are respectively disposed on the left and right sides of the tray along the moving direction. The buffer is also disposed between the two clamping members arranged opposite each other.

[0032] In this embodiment, the pallet positioning assembly 2 uses two clamping members to clamp the pallet to be transferred above the conveyor device 1 from both sides. After waiting for the transmission belt to become empty, the pallet plate 22 descends to lower the pallet onto the two transmission belts, achieving precise positioning and automatic transfer of the pallet on the conveyor device 1. The two clamping members clamp the pallet from both sides to achieve the first positioning of the pallet, ensuring that the pallet is centered in the horizontal direction. The pallet plate 22 rises to support the bottom of the pallet, and the two clamping members move away from each other to release the pallet. Then, the pallet plate 22 descends automatically and accurately places the pallet onto the two transmission belts without manual intervention, improving the transfer efficiency and positioning accuracy of the pallet. The buffer member cushions the pallet plate 22 to absorb mechanical vibration and impact, prevents the pallet plate 22 from making hard contact with the base plate 21, and prevents the pallet from shaking or shifting. The buffer member also cushions and limits the two clamping members, further preventing the pallet from being mechanically damaged by the two clamping members.

[0033] In one embodiment of the present invention, the base plate 21 is fixed on the conveying device 1, and the pallet 22 is horizontally arranged in the clearance space. When the pallet 22 is higher than the first transmission belt 11 and the second transmission belt 12, the pallet on the first transmission belt 11 and the second transmission belt 12 is lifted by the pallet 22. Conversely, the pallet can fall on the first transmission belt 11 and the second transmission belt 12. The first driver 221 and the second driver 238 are preferably cylinders.

[0034] In one embodiment of this utility model, the buffer includes a first buffer 24, a second buffer 242, and a third buffer 241. The third buffer 241 is disposed between the tray 22 and the base plate 21 to buffer the tray 22. The two clamping members are a first clamping member 23a and a second clamping member 23b. The first buffer 24 and the second buffer 242 are disposed between the first clamping member 23a and the second clamping member 23b. The first buffer 24 is used to buffer and limit the first clamping member 23a. Before the first clamping member 23a contacts the tray, the first buffer 24 abuts against the first clamping member 23a to buffer and limit it, preventing one end of the tray from being damaged by the first clamping member 23a. Similarly, the second buffer 242 is used to buffer and limit the second clamping member 23b. The principle is the same and will not be described again.

[0035] In one embodiment of the present invention, two second drivers 238 are included, which are respectively used to drive the first clamping member 23a and the second clamping member 23b to move.

[0036] In one embodiment of this utility model, the first clamping member 23a and the second clamping member 23b are distributed on both sides of the conveying device 1 along the moving direction. It can be understood that the first clamping member 23a is located on the outside of the first transmission belt 11 and the second clamping member 23b is located on the outside of the second transmission belt 12. The purpose is to ensure that the first clamping member 23a and the second clamping member 23b do not interfere with the tray on the transmission belt.

[0037] In one embodiment of this utility model, four positioning posts 222 are arranged in an array on the pallet. The four positioning posts 222 are vertically arranged on the surface of the pallet plate 22. The four positioning posts 222 pass through the four through holes of the pallet respectively, and are used to position the pallet to prevent the pallet from swaying or shifting horizontally during lifting and lowering, thereby improving the positioning accuracy of the pallet.

[0038] In one embodiment of the present invention, each positioning post 222 is provided with an elastic colloid 223 on its top. The elastic colloid 223 can buffer the impact force when the positioning post 22 contacts the tray, reduce tray wear and noise. The elastic colloid 223 is preferably urethane with excellent wear resistance.

[0039] In one embodiment of the present invention, the elastic colloid 223 is configured as a cylinder, and the elastic colloid 223 is coaxially arranged with the positioning post 222, and the diameter of the elastic colloid 223 is the same as the diameter of the positioning post.

[0040] In one embodiment of the present invention, the sensor further includes a first sensor 251 and a second sensor 25. The first sensor 251 is distributed on the tray 22, and the second sensor 25 is disposed on the two clamping members. The first sensor 251 is used to detect whether there is a tray on the tray 22, and the second sensor 25 is used to detect whether there is a tray on the two clamping members.

[0041] In one embodiment of this utility model, the clamping member is provided with a receiving groove 233, and the sensor is disposed in the receiving groove 233. The sensor is accommodated by the clearance groove to prevent the tray from crushing the sensor.

[0042] In one embodiment of the present invention, both ends of the two clamping members along the moving direction are provided with sensors and receiving grooves 233.

[0043] In one embodiment of this utility model, the first clamping member 23a and the second clamping member 23b are each provided with a first abutting portion 232 and abutting portion 234. For the first clamping member 23a, it is used to support one end of the tray, and the two second abutting portions 234 abut against both ends of the tray along the moving direction. The first abutting portion 232 also abuts against one end of the tray along the moving direction of the clamping member. For the second clamping member 23b, it is used to support the other end of the tray, and the two second abutting portions 234 abut against both ends of the tray along the moving direction. The first abutting portion 232 also abuts against the other end of the tray along the moving direction of the clamping member. Therefore, the first clamping member 23a and the second clamping member 23b clamp the tray from four directions to prevent the tray from swaying horizontally during lifting and lowering.

[0044] In one embodiment of the present invention, the second abutment portion 234 is provided with a guide slope 2341. The guide slopes 2341 of the two second abutment portions 234 together form a flared mouth to guide the two corners of the square tray, so that the tray itself can self-adjust and finally align with the tray plate 22 below.

[0045] In one embodiment of this utility model, the positioning mechanism further includes four slide rails and four sliders. The four sliders are evenly distributed on the two clamping members, and the two sliders are distributed at both ends of the clamping members along the moving direction. The two sliders are slidably connected to the two slide rails respectively. The cooperation between the sliders and the slide rails ensures that the two clamping members move smoothly and accurately.

[0046] In one embodiment of the present invention, the slide rail includes a first slide rail 235 and a second slide rail 236 disposed at one end of the support plate 22. The two sliders of the first clamping member 23a are respectively slidably connected to the first slide rail 235 and the second slide rail 236 to ensure the parallelism of the clamping member.

[0047] In one embodiment of this utility model, both clamping members are positioned above the two transmission belts. When the pallet is placed on the two clamping members, the pallet is located above the two transmission belts, ensuring that the pallet transfer path is unobstructed.

[0048] In one embodiment of this utility model, the tray 22 is provided with four guide posts, and the base plate 21 is provided with four guide holes corresponding to the four guide posts. The guide posts pass through the guide holes one by one, and the tray 22 is precisely guided by the guide posts and guide holes to ensure that the positioning post 222 can accurately pass through the through hole of the tray. Adjacent guide posts, such as the first guide post 224 and the second guide post 227, are connected by a connecting plate 225. The connecting plate 225 is located below the base plate 21 and is used to limit the guide posts to prevent them from disengaging from the guide holes of the base plate 21. A fourth buffer 226 is provided between the connecting plate 225 and the base plate 21. The fourth buffer 226 is used to buffer the whole composed of the connecting plate 225 and the guide posts to prevent the connecting plate 225 from making hard contact with the bottom of the base plate 21, thereby reducing noise.

[0049] In one embodiment of the present invention, the positioning mechanism further includes two supports 231, which are distributed on the left and right sides of the conveying device along the moving direction. Two sliders are connected to the bottom of the supports 231. The first clamping member 23a and the second clamping member 23b are respectively disposed on the two supports 231. The buffer members are used to buffer and limit the support 231.

[0050] The working principle of the pallet positioning component described in this utility model is as follows:

[0051] The robotic arm places the pallet on the first clamping member 23a and the second clamping member 23b. After the second sensor 25 detects the pallet, the second driver 238 drives the first clamping member 23a and the second clamping member 23b to move closer together to clamp the two ends of the pallet. When there is no space on the conveyor belt, the first driver 221 drives the pallet plate 22 to rise to support the pallet. After the first sensor 251 detects the pallet, the second driver 238 drives the first clamping member 23a and the second clamping member 23b to move away from each other to release the pallet. Then, the first driver 221 drives the pallet plate 22 to descend and place the pallet on the conveyor belt until the positioning post 222 disengages from the pallet and stops. Finally, the conveyor belt transfers the pallet to the next station, completing the pallet transfer.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
