[0002] In the rapidly developing 21st century, science and technology are advancing at a high speed, and various electronic products are emerging in an endless stream. Most of these electronic products are composed of PCB boards and various electronic components. When mounting electronic components on a PCB, the first step is to separate the PCB board or electronic components from the tray. After the materials are separated, the tray needs to be sorted.

[0003] The current extraction tray sorting process involves manually sorting out empty extraction trays after they are full of material, and then replacing them with new ones full of material. This process not only increases labor costs but also reduces production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic sorting device for extraction trays, which can replace manual labor with machinery to realize the automatic sorting of extraction trays, reduce labor costs, and improve production efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An automatic sorting device for extraction trays includes three hoppers arranged side by side for holding extraction trays. The bottom of the hoppers is provided with a lifting component for lifting the extraction trays. The top of the hoppers is provided with a transfer frame. A clamping component for clamping the lifted extraction trays is slidably arranged on the transfer frame. A transverse component is provided on the transfer frame for driving the clamping component to slide on the transfer frame.

[0007] Optionally, the lifting assembly includes a support plate for supporting the extraction tray, two lifting belts for moving the support plate vertically, a first driving wheel and two first driven wheels for cooperating with the lifting belts, a lifting motor for driving the first driving wheel to rotate, and a synchronous pulley shaft for synchronously driving the two lifting belts. The support plate is located inside the hopper and is slidably connected to the hopper. The lifting motor is located below the support plate and is fixedly connected to the hopper. The first driving wheel is fixedly sleeved on the output shaft of the lifting motor. The first driven wheels are rotatably mounted on the top of the hopper. The bottom end of the lifting belt is sleeved on the synchronous pulley shaft, and the top end of the lifting belt is sleeved on the outer ring of the first driven wheel. One side of the lifting belt is fixedly connected to the support plate, and the first driving wheel is connected to the synchronous pulley shaft for transmission.

[0008] Optionally, the clamping assembly includes a first clamping slide rod located on one side of the lifted extraction tray and a second clamping slide rod located on the other side of the lifted extraction tray and corresponding to the first clamping slide rod, and a first gripper cylinder for driving the first and second clamping slide rods to clamp the extraction tray; the first gripper at the movable end of the first gripper cylinder is fixedly connected to the first clamping slide rod, the second gripper at its movable end is fixedly connected to the second clamping slide rod, and its fixed end is fixedly connected to the transverse moving assembly; both the first and second clamping slide rods are slidably connected to the transfer frame.

[0009] Optionally, the clamping assembly further includes two second clamping claw cylinders; a third clamping slide rod is slidably disposed at one end of the first clamping slide rod and the second clamping slide rod, located at one end of the lifted extraction plate; a fourth clamping slide rod is slidably disposed at the other end of the first clamping slide rod and the second clamping slide rod, located at the other end of the lifted extraction plate; the first claw at the movable end of the second clamping claw cylinder is fixedly connected to the third clamping slide rod, and the second claw at its movable end is fixedly connected to the fourth clamping slide rod.

[0010] Optionally, the transverse assembly also includes a transverse belt for driving the first gripper cylinder to move horizontally, a second driving pulley and a second driven pulley for cooperating with the transverse belt drive, and a transverse motor for driving the second driving pulley to rotate; the transverse motor is fixedly connected to one end of the transfer frame, the second driving pulley is fixedly sleeved on the output shaft of the transverse motor, the second driven pulley is rotatably mounted on the other end of the transfer frame, one end of the transverse belt is sleeved on the outer ring of the second driving pulley, the other end of the transverse belt is sleeved on the outer ring of the second driven pulley, and one side of the transverse belt is fixedly connected to the fixed end of the first gripper cylinder.

[0011] Optionally, the top of the hopper is equipped with a sensor to sense when the extraction disc is lifted to a preset position.

[0012] Optionally, lifting cylinders are installed at the four corners of the transfer frame to raise the height of the transfer frame. The movable end of the lifting cylinder is fixedly connected to the transfer frame, and the fixed end of the lifting cylinder is fixedly connected to the hopper.

[0013] In summary, the above embodiments of this utility model have the following beneficial effects: the lifting component lifts the multi-layer extraction trays located in the full material bin (one of the bins) layer by layer to the preset position. After the clamping component clamps the top extraction tray, the lateral movement component indirectly drives the extraction tray to the working position through the clamping component. Then the extraction tray waits for the external robot to transfer the material. After the material transfer is completed, the lateral movement component indirectly drives the extraction tray to move above the empty material bin (one of the bins) through the clamping component. The empty extraction tray falls into the empty material bin by gravity. Then the lifting component in the full material bin lifts the new full material extraction tray, and the clamping component and the lateral movement component move laterally above it to clamp and transfer. This process is repeated until the extraction trays in the full material bin are emptied. Thus, this utility model can effectively reduce labor costs, mechanize tedious manual operations, and greatly improve production efficiency. Attached Figure Description

Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] This utility model provides an automatic sorting device for extraction trays, such as... Figure 1-2 As shown, it includes three hoppers 1 arranged side by side for holding the extraction trays 7. The bottom of the hopper 1 is provided with a lifting component 2 for lifting the extraction trays 7. The top of the hopper 1 is provided with a transfer frame 3. A clamping component 4 for clamping the lifted extraction trays 7 is slidably arranged on the transfer frame 3. A transverse component 5 for driving the clamping component 4 to slide on the transfer frame 3 is provided on the transfer frame 3.

[0024] In this embodiment, the hopper 1 is a columnar body made of sheet metal, divided into two parts by a baffle. The upper part is used to hold the stacked extraction trays 7, and the lower part is divided to provide installation space for other components. The three hoppers 1 are arranged together from left to right and are fixed to each other. The hopper 1 in the middle is an empty hopper for recovering extraction trays 7 that do not hold materials, and the hoppers 1 at the left and right ends are full hoppers for placing extraction trays 7 that hold materials. The bottom of each hopper 1 is equipped with a lifting assembly 2 by screws and other conventional connection methods, and the transfer frame 3 is installed on the top of the three hoppers 1 by screws and other conventional connection methods. The clamping assembly 4 is installed on the top of the transfer frame 3 by screws using a conventional linear slide rail assembly, and can slide from above the leftmost hopper 1 to above the rightmost hopper 1. The lateral movement assembly 5 is installed on the side of the transfer frame 3 by screws and other conventional connection methods, and its drive end is fixed to the clamping assembly 4 by screws and conventional connection methods.

[0025] This invention uses a lifting component 2 to lift the multi-layer extraction trays 7 located in a full material hopper layer by layer to a preset position. After the clamping component 4 clamps the top extraction tray 7, the lateral movement component 5 indirectly moves the extraction tray 7 to the work station (the station for assembling the materials on the extraction tray 7) through the clamping component 4. Then, the extraction tray 7 waits for an external robotic arm to transfer the materials. After the materials are transferred, the lateral movement component 5 indirectly moves the extraction tray 7 to the top of the empty material hopper through the clamping component 4. The empty extraction tray falls into the empty material hopper by gravity. Then, the lifting component 2 in the full material hopper lifts a new full material extraction tray, and the clamping component 4 and the lateral movement component 5 move laterally above it to clamp and transfer the material. This process is repeated until the extraction trays in the full material hopper are emptied. This invention can effectively reduce labor costs, mechanize tedious manual operations, and greatly improve production efficiency.

[0026] Furthermore, the lifting assembly 2 includes a support plate 21 for supporting the extraction tray 7, two lifting belts 22 for driving the support plate 21 to move vertically, a first driving wheel 23 and two first driven wheels 24 for cooperating with the lifting belts 22 to drive the transmission, a lifting motor 25 for driving the first driving wheel 23 to rotate, and a synchronous pulley shaft 26 for synchronously driving the two lifting belts 22; the support plate 21 is located inside the hopper 1 and is slidably connected to the hopper 1, the lifting motor 25 is located below the support plate 21 and is fixedly connected to the hopper 1, the first driving wheel 23 is fixedly sleeved on the output shaft of the lifting motor 25, the first driven wheels 24 are rotatably arranged at the top of the hopper 1, the bottom end of the lifting belt 22 is sleeved on the synchronous pulley shaft 26, the top end of the lifting belt 22 is sleeved on the outer ring of the first driven wheels 24, one side of the lifting belt 22 is fixedly connected to the support plate 21, and the first driving wheel 23 is connected to the synchronous pulley shaft 26 for transmission.

[0027] like Figure 2-3As shown, the synchronous pulley shaft 26 consists of a rotating shaft and three pulleys (not shown in the attached diagram), with the rotating shaft and three pulleys being relatively fixed. The synchronous pulley shaft 26 is mounted on the bottom of the hopper 1 via bearings and is located below the lifting motor 25. The lifting motor 25 is specifically a servo motor, which is fixedly mounted on the bottom of the hopper 1 with screws. Its output shaft is fixedly mounted with a first driving pulley 23 via a key connection. The first driving pulley 23 is connected to the pulley in the middle of the synchronous pulley shaft 26 via a transmission belt. Two first driven pulleys 24 are respectively mounted on both sides of the top of the hopper 1 via screws or other conventional mounting methods. Both sides of the support plate 21 are mounted inside the hopper 1 via conventional linear slide rail assemblies, allowing it to slide up and down inside the hopper 1. Two lifting belts 22 are located on both sides of the support plate 21, with their top ends wrapped around the outer ring of the corresponding first driven pulley 24 and their bottom ends wrapped around the outer ring of the synchronous pulley shaft 26 and its corresponding pulley. The lifting belt 22 is a conventional annular transmission belt with drive teeth on the inner side. One side of the belt is fixedly connected to one side of the support plate 21 through a conventional belt connecting clamp 27, thereby driving the support plate 21 to slide up and down.

[0028] This utility model utilizes a lifting motor 25 as the lifting power, and with the cooperation of a synchronous pulley shaft 26 and two lifting belts 22, it simultaneously and precisely lifts both sides of the support plate 21 to the same height. Compared with other lifting components that use cylinders or oil cylinders as the lifting power, it has the advantages of high lifting accuracy, fast lifting speed, and stable lifting process.

[0029] Furthermore, the clamping assembly 4 includes a first clamping slide bar 41 located on one side of the lifted extraction tray 7 and a second clamping slide bar 42 located on the other side of the lifted extraction tray 7 and corresponding to the first clamping slide bar 41. A first gripper cylinder 43 is used to drive the first clamping slide bar 41 and the second clamping slide bar 42 to clamp the extraction tray 7. The first gripper at the movable end of the first gripper cylinder 43 is fixedly connected to the first clamping slide bar 41, and the second gripper at its movable end is fixedly connected to the second clamping slide bar 42. Its fixed end is fixedly connected to the transverse moving assembly 5. Both the first clamping slide bar 41 and the second clamping slide bar 42 are slidably connected to the transfer frame 3.

[0030] like Figure 4-6As shown, the first clamping slide bar 41 and the second clamping slide bar 42 are symmetrical and elongated, and are mounted on the transfer frame 3 via a conventional linear slide rail assembly. Both the first clamping slide bar 41 and the second clamping slide bar 42 have anti-slip locking structures on the side near the extraction tray 7 to stably clamp the extraction tray 7. The first gripper cylinder 43 has a first gripper and a second gripper. When the cylinder is inflated, the first and second grippers clamp together; when the cylinder is not inflated, the first and second grippers are open. Both the first and second grippers are fixedly connected to the first clamping slide bar 41 and the second clamping slide bar 42 respectively via L-shaped connecting blocks (shown in the attached diagram but not labeled). When the first gripper cylinder 43 is inflated, the first clamping slide bar 41 and the second clamping slide bar 42 clamp both sides of the extraction tray 7. The elongated structure of the first clamping slide bar 41 and the second clamping slide bar 42 provides more force-bearing area for the extraction tray 7, allowing the extraction tray 7 to be stably moved to the working position.

[0031] Furthermore, the clamping assembly 4 also includes two second clamping claw cylinders 44; a third clamping claw 45 is slidably disposed at one end of the first clamping claw 41 and the second clamping claw 42, located at one end of the lifted extraction plate 7; a fourth clamping claw 46 is slidably disposed at the other end of the first clamping claw 41 and the second clamping claw 42, located at the other end of the lifted extraction plate 7; the first claw at the movable end of the second clamping claw cylinder 44 is fixedly connected to the third clamping claw 45, and the second claw at its movable end is fixedly connected to the fourth clamping claw 46.

[0032] like Figure 4-6 As shown, the third clamping slide bar 45 and the fourth clamping slide bar 46 are respectively mounted at both ends of the first clamping slide bar 41 and the second clamping slide bar 42 via conventional linear slide rail assemblies. The second gripper cylinder 44 is the same as the first gripper cylinder 43, and is also fixedly connected to the corresponding first clamping slide bar 41 and second clamping slide bar 42 via L-shaped connecting blocks. The first clamping slide bar 41 and the second clamping slide bar 42 are used to clamp both ends of the extraction tray 7, while the third clamping slide bar 45 and the fourth clamping slide bar 46 are used to clamp both ends of the extraction tray 7, thereby further improving the stability of the extraction tray 7 being clamped.

[0033] Furthermore, the transverse assembly 5 also includes a transverse belt 51 for driving the first gripper cylinder 43 to move horizontally, a second driving wheel 52 and a second driven wheel 53 for cooperating with the transverse belt 51 to drive the transmission, and a transverse motor 54 for driving the second driving wheel 52 to rotate. The transverse motor 54 is fixedly connected to one end of the transfer frame 3, the second driving wheel 52 is fixedly sleeved on the output shaft of the transverse motor 54, the second driven wheel 53 is rotatably disposed at the other end of the transfer frame 3, one end of the transverse belt 51 is sleeved on the outer ring of the second driving wheel 52, the other end of the transverse belt 51 is sleeved on the outer ring of the second driven wheel 53, and one side of the transverse belt 51 is fixedly connected to the fixed end of the first gripper cylinder 43.

[0034] like Figure 4-5 As shown, the transverse motor 54 is specifically a servo motor, which is fixedly mounted on the right side of the transfer frame 3 with screws. Its output shaft is fixedly mounted on the second drive wheel 52 via a flat key connection. The second driven wheel 53 is mounted on the left side of the transfer frame 3 with screws or other conventional mounting methods. The left end of the transverse belt 51 is wrapped around the outer ring of the second driven wheel 53, and the right end is wrapped around the outer ring of the second drive wheel 52. The transverse belt 51 is a conventional annular transmission belt with drive teeth on the inner side. One side of it is fixedly connected to the cylinder seat of the first gripper cylinder 43 via a conventional belt connecting clamp 55, thereby driving the clamping assembly 4 to slide left and right.

[0035] This utility model uses a transverse motor 54 as a power source, and the clamping assembly 4 slides left and right in cooperation with the transverse belt 51, the second driving wheel 52 and the two second driven wheels 53, which has the advantages of high transverse accuracy and fast transverse speed.

[0036] Furthermore, the top of the hopper 1 is equipped with a sensor (not shown in the attached figure) for sensing that the extraction plate 7 has been lifted to a preset position. When the sensor senses that the top extraction plate 7 has been lifted to the preset position, it sends a feedback signal to the PLC controller, which then controls the lifting motor 25 to stop rotating.

[0037] Furthermore, the four corners of the transfer frame 3 are provided with lifting cylinders 31 for raising the height of the transfer frame 3. The movable end of the lifting cylinder 31 is fixedly connected to the transfer frame 3, and the fixed end of the lifting cylinder 31 is fixedly connected to the hopper 1.

[0038] like Figure 1 and Figure 4As shown, the four corners of the transfer frame 3 are mounted on the structure formed by the three material bins 1 via lifting cylinders 31 (the attached diagram only shows the telescopic rods of the lifting cylinders 31, not the cylinder base). This arrangement allows the clamped and fixed extraction tray 7 to be lifted upwards a certain distance, with the bottom of the extraction tray 7 suspended in the air. When the material tray 7 has a relatively soft structure, elastic deformation may cause the robot arm to fail to pick up the material. Supports can be added to its bottom.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
