[0003] However, with the continuous development of automation technology, manual handling of loading and unloading processes has seriously affected production efficiency, making it difficult to achieve fast, continuous and stable operation. Utility Model Content

[0004] The main purpose of this utility model is to propose a loading and unloading device that aims to enable the workpiece to be loaded and unloaded quickly and continuously.

[0005] To achieve the above objectives, the present invention provides a loading and unloading device comprising:

[0006] The frame has a loading station and a unloading station arranged at intervals, as well as a feeding waiting area connected to the loading station and a discharging waiting area connected to the unloading station.

[0007] A carrying mechanism, comprising multiple stacked trays, each tray carrying at least one workpiece, the carrying mechanism being located at the loading station;

[0008] Two material handling mechanisms are provided, one for the loading station and one for the unloading station. The material handling mechanism at the loading station is used to transport the carrying mechanism at the loading station to the feeding waiting area, so that the robot arm can take the workpiece off the pallet in the feeding waiting area and leave the empty pallet in the feeding waiting area.

[0009] A conveying mechanism is provided on the frame. The conveying mechanism is used to move the empty pallets in the feeding waiting area one by one to the unloading waiting area, so as to wait for the robot to transfer the processed workpieces to the empty pallets, and to stack the pallets in the unloading waiting area. Another material conveying mechanism is used to transfer the carrying mechanism in the unloading waiting area to the unloading station.

[0010] In one embodiment, the conveying mechanism includes:

[0011] The support frame is slidably mounted on the frame;

[0012] A retrieval component is provided on the support frame, and at least one retrieval component is provided for retrieving an empty pallet;

[0013] A first drive assembly is driven to the support frame, and the first drive assembly drives the support frame to slide along a first direction on the frame to transfer the empty pallet in the feeding waiting area to the discharging waiting area.

[0014] In one embodiment, the conveying mechanism further includes a second drive assembly and a mounting base. The picking assembly is disposed on the mounting base, and the first drive assembly is disposed on the side of the support frame away from the mounting frame. The first drive assembly is drivenly connected to the mounting base to drive the mounting base and the picking assembly to move up and down.

[0015] In one embodiment, the conveying mechanism further includes a mounting frame extending along a first direction, the mounting frame being fixed to the frame, the first drive assembly being disposed on the mounting frame to drive the support frame to slide on the mounting frame, a detection baffle being provided on the side of the support frame facing the mounting frame, and detection sensors being respectively provided on the mounting frame at positions corresponding to the feeding waiting area and the discharging waiting area, the detection sensors being used to detect the detection baffle.

[0016] In one embodiment, the handling assembly includes an adsorption structure and / or a gripper structure.

[0017] In one embodiment, the loading and unloading equipment further includes a vision module, which is disposed on the frame and located above the feeding waiting area.

[0018] In one embodiment, the material conveying mechanism includes a first conveying assembly, the first conveying assembly comprising:

[0019] A support base is located at the bottom of the bearing mechanism;

[0020] A lifting drive structure is provided on the frame, and the lifting drive structure is driven to connect with the support base to drive the support base and the load-bearing mechanism to lift.

[0021] One of the first conveying components is used to transport the carrying mechanism of the loading station to the feeding waiting area, and the other first conveying component is used to transport the carrying mechanism of the unloading station to the unloading station.

[0022] In one embodiment, the material conveying mechanism further includes a second conveying assembly, which includes two conveyor belts spaced apart. The conveyor belts are used to support the bottom of both sides of the bearing mechanism. The support seat is disposed between the two conveyor belts and moves up and down between the two conveyor belts.

[0023] In one embodiment, the conveyor belt carries a plurality of the carrying mechanisms, which are spaced apart along the length of the conveyor belt.

[0024] In one embodiment, the top of the tray is provided with at least one positioning groove for placing a workpiece.

[0025] In this invention, the frame is equipped with a loading station and a unloading station. The end of the loading station is a feeding waiting area, and the end of the unloading station is a discharging waiting area. A carrying mechanism is located at the loading station. A conveying mechanism at the loading station transports the carrying mechanism to the feeding waiting area. A robotic arm removes the workpiece from the pallet in the feeding waiting area and sends it for processing. After removing the workpiece, the robotic arm leaves the pallet in the feeding waiting area. A conveying mechanism transfers the empty pallet to the discharging waiting area. The robotic arm then places the processed workpiece onto the empty pallet in the discharging waiting area, and the above actions are repeated. When the workpiece on the pallet in the feeding waiting area is removed, the conveying mechanism transfers the empty pallet to the empty pallet in the discharging waiting area. The workpieces are placed on top of the pallet above the infeed waiting area. Once the pallet is empty, it is transferred to the unloading waiting area and stacked on top of the previous pallet. The pallets continue to be stacked after they are full of processed workpieces, until all the workpieces carried by the carrying mechanism are processed. Then all the pallets are transferred to the unloading waiting area. The material handling mechanism at the unloading station moves the carrying mechanism carrying the processed workpieces in the unloading waiting area to the unloading station and away from the unloading waiting area. The two material handling mechanisms work independently at the loading and unloading stations, which improves the efficiency of loading and unloading workpieces, reduces manual intervention, reduces costs, and improves the consistency of the work process, thus improving the quality of workpiece processing and making the entire work process more automated.

[0041] In the product processing, the loading and unloading of workpieces is a key link in the production process, and traditionally this operation is mainly done manually.

[0042] However, with the continuous development of automation technology, manual handling of loading and unloading processes has seriously affected production efficiency, making it difficult to achieve fast, continuous and stable operation.

[0043] This utility model proposes a material loading and unloading device.

[0044] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the loading and unloading equipment includes a frame 100, a bearing mechanism 200, a conveying mechanism 300, and a handling mechanism 400. The frame 100 has a loading station 101 and a unloading station 102 arranged at intervals, as well as a feeding waiting area 103 connected to the loading station 101 and a discharging waiting area 104 connected to the unloading station 102. The bearing mechanism 200 includes a plurality of stacked trays 210, each tray 210 carrying at least one workpiece. The bearing mechanism 200 is located at the loading station 101. Two conveying mechanisms 300 are provided, one for the loading station 101 and one for the unloading station 102. The material handling mechanism 300 of 1 is used to transport the carrying mechanism 200 of the loading station 101 to the feeding waiting area 103, so that the robot can take the workpieces off the pallets 210 on the feeding waiting area 103 and leave the empty pallets 210 in the feeding waiting area 103; the conveying mechanism 400 is provided on the frame 100, and the conveying mechanism 400 is used to move the empty pallets 210 of the feeding waiting area 103 one by one to the unloading waiting area 104, so that the robot can transfer the processed workpieces to the empty pallets 210, and realize the stacking of pallets 210 in the unloading waiting area 104; another material handling mechanism 300 is used to transfer the carrying mechanism 200 of the unloading waiting area 104 to the unloading station 102.

[0045] In the technical solution of this utility model, a loading station 101 and a unloading station 102 are provided on the frame 100. The end of the loading station 101 is a feeding waiting area 103, and the end of the unloading station 102 is a discharging waiting area 104. The carrying mechanism 200 is located at the loading station 101. The carrying mechanism 300 at the loading station 101 transports the carrying mechanism 200 to the feeding waiting area 103. The robot arm takes the workpiece from the pallet 210 in the feeding waiting area 103 and sends it for processing. After the robot arm takes the workpiece, it leaves the pallet 210 in the feeding waiting area 103. The empty pallet 210 is transferred to the discharging waiting area 104 by the transport mechanism 400. The robot arm then places the processed workpiece on the empty pallet 210 in the discharging waiting area 104 and repeats the above actions. When the workpiece on the pallet 210 in the feeding waiting area 103 is taken away, the transport mechanism 400 transfers the empty pallet 210 to the discharging waiting area 104. Above the pallet 210 containing the processed workpieces in the waiting area 104, i.e., after the pallet 210 in the feeding waiting area 103 is empty, it is transferred to the unloading waiting area 104 and stacked on top of the previous pallet 210. After the pallet 210 is full of processed workpieces, the pallets 210 continue to be stacked until all the workpieces carried by the carrying mechanism 200 are processed. Then all the pallets 210 are transferred to the unloading waiting area 104. The material handling mechanism 300 at the unloading station 102 moves the carrying mechanism 200 containing the processed workpieces in the unloading waiting area 104 to the unloading station 102 and away from the unloading waiting area 104. The two material handling mechanisms 300 work independently at the feeding station 101 and the unloading station 102, respectively, which improves the efficiency of loading and unloading workpieces, reduces manual intervention, reduces costs, and improves the consistency of the work process, thus improving the quality of workpiece processing and making the entire work process more automated.

[0046] Specifically, the loading and unloading equipment is located on one side of the processing equipment, and a robotic arm is installed between the loading and unloading equipment and the processing equipment. The robotic arm transfers the workpieces from the loading and unloading equipment to the processing equipment for processing, and after processing, transfers the workpieces from the processing equipment back to the loading and unloading equipment for unloading. The processing equipment can be a hot melt machine or a dispensing machine, etc., without limitation. The loading and unloading equipment includes a frame 100, with feet at the four corners of the bottom of the frame 100. The feet are screwed to the frame 100 to adjust the height of the frame 100. Rollers are also provided at the bottom of the frame 100. When the feet are screwed up so that they are higher than the rollers, the rollers contact the ground, facilitating the movement of the entire frame 100. The frame 100 is provided with a loading station 101 and an unloading station 102. The loading station 101... The loading station 101 and unloading station 102 can be configured to extend horizontally or vertically. In this embodiment, the loading station 101 and unloading station 102 extend horizontally. The feeding waiting area 103 and the unloading waiting area 104 are respectively located at the top of the loading station 101 and the unloading station 102 and are connected to them, so that the material handling mechanism 300 can transport the carrying mechanism 200 between the loading station 101 and the feeding waiting area 103, and transport the carrying mechanism 200 carrying the processed workpiece between the unloading station 102 and the unloading waiting area 104. The workpiece is transferred by the robot arm and the handling mechanism 400 is used to move the pallet 210 between the feeding waiting area 103 and the unloading waiting area 104, thereby realizing the transfer of the position of the pallet 210 and improving the efficiency of workpiece processing.

[0047] Alternatively, please refer to Figure 5 In one embodiment, at least one positioning groove 211 is provided on the top of the pallet 210. The positioning groove 211 is used to place the workpiece. The positioning grooves 211 are spaced apart on the top of the pallet 210. The workpiece is placed in the positioning groove 211 and is lower than the top surface of the pallet 210. This not only positions the workpiece and prevents it from shaking when the pallet 210 moves, but also avoids squeezing the workpiece and affecting its processing quality when the pallets 210 carrying the workpiece are stacked. The bottom of the pallet 210 is provided with a clearance groove around the positioning groove 211 so that the bottom of the positioning groove 211 protrudes, which can reduce the weight of the pallet 210 and facilitate transportation. The pallet 210, as a carrier, can be made of aluminum alloy or engineering plastic.

[0048] In an embodiment of this utility model, the conveying mechanism 400 includes:

[0049] Support frame 410 is slidably mounted on frame 100;

[0050] A picking component 420 is provided on the support frame 410, and at least one picking component 420 is provided for picking up an empty pallet 210;

[0051] The first drive assembly 430 is driven to connect with the support frame 410. The first drive assembly 430 drives the support frame 410 to slide along the first direction on the frame 100 to transfer the empty pallet 210 in the feeding waiting area 103 to the discharging waiting area 104.

[0052] Please refer to Figure 1 and Figure 3 The conveying mechanism 400 includes a first drive assembly 430, which drives the connected support frame 410 so that the support frame 410 slides on the frame 100 in the horizontal direction, i.e., the first direction. A picking assembly 420 is provided on one side of the support frame 410. Driven by the first drive assembly 430, the picking assembly 420 can move between the feeding waiting area 103 and the discharging waiting area 104. That is, when the robot arm takes away the workpiece on the tray 210 of the feeding waiting area 103 and leaves an empty tray 210. The transfer component 420 moves the empty pallet 210 from the feeding waiting area 103 to the unloading waiting area 104, so that it can receive the processed workpieces in the unloading waiting area 104. This does not affect the subsequent workpiece retrieval in the feeding waiting area 103, nor does it affect the unloading waiting area 104 receiving the processed workpieces. Moreover, through the cooperation of the transfer component 420 and the first drive component 430, the transfer of the pallet 210 can be realized with reduced manual intervention, thereby improving the automation of the entire transfer process and thus improving the processing efficiency of the workpiece products.

[0053] The first drive assembly 430 uses a drive motor and a belt. The two ends of the belt are respectively wound with a drive pulley and a driven pulley. The drive motor drives the drive pulley, causing it to rotate and thus rotating the belt and the driven pulley. The support frame 410 is mounted on the belt via a mounting block, so that the support frame 410 and the handling assembly 420 move with the rotation of the belt. The first drive assembly 430 can also adopt a linear drive structure such as a cylinder, a lead screw and nut pair, or an electric telescopic rod. Its output end, such as the piston rod of the cylinder, is fixedly connected to the support frame 410. As the piston rod extends and retracts, it drives the support frame 410 and the handling assembly 420 to move horizontally, thus completing the transfer of the pallet 210.

[0054] In an embodiment of the present invention, the conveying mechanism 400 further includes a second drive component 440 and a mounting base 450. The picking component 420 is disposed on the mounting base 450. The first drive component 430 is disposed on the side of the support frame 410 away from the mounting frame 460. The first drive component 430 is drivenly connected to the mounting base 450 to drive the mounting base 450 and the picking component 420 to rise and fall.

[0055] Please refer to Figure 3The mounting base 450 is located on one side of the support frame 410. Specifically, the mounting base 450 includes a vertical plate 451. A first frame 452 is provided on one side of the vertical plate 451. The first frame 452 extends along a second direction, which is also horizontal and perpendicular to the first direction. A second frame 453 extending along the first direction is provided on the side of the first frame 452 facing downwards. The lifting component 420 is located on the side of the second frame 453 facing downwards, facilitating the lifting component 420 to grasp the pallet 210. A second drive component 440 is provided on the support frame 410. The second drive component 440 is drivenly connected to the vertical plate 451 to drive the vertical plate 451 to rise and fall on the support frame 410. That is, when the lifting component 420 wants to grasp the pallet 210, the first lifting component drives the support frame 410 to move above the feeding waiting area 103, and the second drive component... The first lifting component drives the support frame 451 to descend, causing the pick-up component 420 to descend and approach and grab the pallet 210. After the pallet 210 is grabbed, the second driving component 440 drives the support plate 451 to rise, thereby raising the pallet 210 to avoid affecting other structures during the lateral movement of the pallet 210. The first lifting component drives the support frame 410 to move below the discharge waiting area 104. The second driving component 440 drives the support plate 451 to descend, and the pick-up component 420 approaches the discharge waiting area 104 and releases itself from the pallet 210, so that the empty pallet 210 falls in the discharge waiting area 104 to await the finished workpiece. The above actions are repeated until all the empty pallets 210 in the feeding waiting area 103 are transferred to the discharge waiting area 104 and stacked in the discharge waiting area 104. The automation level is high, and the actions are consistent each time, avoiding movement errors.

[0056] The first frame 452 is made of profile material, and multiple first frames 452 are provided. The multiple first frames 452 are spaced apart along the first direction. The first frame 452 has a stable structure, which can prevent the pallet 210 from shaking during the handling process, so that the pallet 210 is always in a relatively stable state. The second drive component 440 adopts a linear drive structure such as a cylinder, hydraulic cylinder or electric telescopic rod. A slide rail extending in the vertical direction is provided on the side of the support frame 410 facing the upright plate 451, and a slider is provided on the side of the upright plate 451 facing the support frame 410. The slider cooperates with the slide rail. During the lifting and lowering process of the upright plate 451, the slider slides on the slide rail, which can prevent the offset during the lifting and lowering process and affect the movement accuracy.

[0057] In embodiments of this utility model, such as Figure 3As shown, the conveying mechanism 400 also includes a mounting frame 460 extending along a first direction. The mounting frame 460 is fixed to the frame 100. A first drive assembly 430 is disposed on the mounting frame 460 to drive the support frame 410 to slide on the mounting frame 460. A detection baffle is provided on the side of the support frame 410 facing the mounting frame 460. Detection sensors 470 are respectively provided on the mounting frame 460 at positions corresponding to the feeding waiting area 103 and the discharging waiting area 104. The detection sensors 470 are used to detect the detection baffle.

[0058] A mounting bracket 460 extending along a first direction is provided on the frame 100. A first drive assembly 430 is mounted on the mounting bracket 460 and slides along the first direction on the mounting bracket 460. A slide rail extending along the first direction is provided on the side of the mounting bracket 460 facing the upright plate 451. A matching slider is provided on the side of the upright plate 451 facing the mounting bracket 460. The slider cooperates with the slide rail, so that under the drive of the first drive assembly 430, the upright plate 451 slides horizontally on the mounting bracket 460, improving the accuracy of the transfer of the tray 210 between the feeding waiting area 103 and the discharging waiting area 104. Detection sensors 470 are spaced along the length direction (i.e., the first direction) on the side of the mounting bracket 460 where the slide rail is provided. Detection baffles are provided on the slider or support frame 410. When the first drive assembly 430 drives the support frame 410 to move horizontally on the mounting frame 460, the detection baffle passes through the detection sensor 470. The detection sensor 470 detects the detection baffle and obtains the position of the support frame 410 and the handling assembly 420. In one embodiment, the detection sensor 470 is respectively set on the mounting frame 460 at the positions corresponding to the feeding waiting area 103 and the discharging waiting area 104. When the detection sensor 470 detects the detection baffle, the detection sensor 470 sends a signal to the control terminal. The controller of the control terminal sends a signal to the first drive assembly 430 to shut it down. At this time, the support frame 410 is stationary above the feeding waiting area 103 or the discharging waiting area 104, waiting to grab or release the workpiece, making the workpiece grabbing and releasing process more efficient and automated.

[0059] In one embodiment, the handling component 420 includes an adsorption structure 421, which includes a vacuum suction cup connected to a vacuum generator. When the handling component 420 approaches the tray 210 and needs to adsorb the tray 210, the vacuum generator is turned on, which reduces the internal air pressure of the vacuum suction cup. Under the action of external atmospheric pressure, the upper surface of the tray 210 is adsorbed, and the tray 210 is firmly gripped. When the handling component 420 moves to the discharge waiting area 104, the vacuum generator is turned off, and the tray 210 is released. The adsorption structure 421 can complete the handling action in a short time when adsorbing and releasing the tray 210, quickly gripping and releasing, reducing handling time, thereby improving production efficiency. Moreover, the adsorption method can also reduce wear on the tray 210 and reduce maintenance frequency.

[0060] In another embodiment, the handling component 420 may also include a gripper structure 422, which includes mechanical grippers, such as cylinder grippers. A pad is provided on the inner side of the gripper to prevent wear on the tray 210. The gripper structure 422 can be opened and closed flexibly, and can be adapted to different sizes of trays 210 by adjusting the degree of opening and closing of the gripper.

[0061] The combination of the adsorption structure 421 and the gripper structure 422 can be adapted to different types of trays 210, making it widely applicable.

[0062] In this embodiment of the invention, the loading and unloading equipment also includes a vision module. The vision module is mounted on the frame 100 and located above the feeding waiting area 103. The vision module is used to locate the workpieces on the trays 210 in the feeding waiting area 103. The vision module includes a CCD camera, an image processing system, and a light source. The CCD camera is mounted above the feeding waiting area 103. When the carrying mechanism 200 moves to the feeding waiting area 103, since the carrying mechanism 200 is composed of multiple trays 210 stacked together, each tray 210 holds multiple workpieces. The CCD camera captures images of the workpieces in the trays 210. The image processing system analyzes and processes the captured images to obtain the XY axis position information of the workpieces and transmits this information to the control terminal. The control terminal sends a signal to the robot arm. The robot arm adjusts its position according to the position signal of the workpieces, making it easier for the robot arm to accurately grasp the workpieces. The precise positioning of the vision module enables the robot arm to quickly and accurately grasp the workpieces, improving production efficiency, reducing manual intervention, lowering labor costs, and improving the consistency of the production process.

[0063] In an embodiment of this utility model, the material conveying mechanism 300 includes a first conveying component 310, which includes:

[0064] Support base 311 is located at the bottom of the bearing mechanism 200;

[0065] The lifting drive structure 312 is located on the frame 100. The lifting drive structure 312 is driven to connect with the support base 311 to drive the support base 311 and the load-bearing mechanism 200 to lift.

[0066] One of the first conveying components 310 is used to transport the carrying mechanism 200 of the loading station 101 to the feeding waiting area 103, and the other first conveying component 310 is used to transport the carrying mechanism 200 of the unloading station 102 to the unloading station 102.

[0067] Please refer to Figure 2 and Figure 4The first conveying component 310 includes a lifting drive structure 312 and a support base 311. The lifting drive structure 312 adopts a translation module, which is vertically arranged to drive the support base 311 to rise and fall. The support base 311 is located at the bottom of the lowest tray 210 of the carrying mechanism 200. When the support base 311 rises, it drives the carrying mechanism 200 to rise. When the carrying mechanism 200 carrying the workpiece reaches the loading station 101, the first conveying component 310 of the loading station 101 is activated. The lifting drive structure 312 drives the support base 311 to rise and drives the carrying mechanism 200 to rise. When the uppermost tray 210 reaches the feeding waiting area 103, it waits for the robot to pick up the workpiece until the robot has taken away all the workpieces carried by the uppermost tray 210. Afterwards, the topmost pallet 210 is empty. The conveying mechanism 400 transfers the topmost empty pallet 210 to the unloading waiting area 104, and the pallet 210 originally located on the second layer becomes the topmost pallet 210. The lifting drive structure 312 drives the support base 311 to rise continuously until it reaches the feeding waiting area 103, and then waits for the robot to pick up the material. The above action is repeated until the bottommost pallet 210 reaches the feeding waiting area 103 with the support of the support base 311, completing the feeding of the carrying mechanism 200. After the last pallet 210 is transferred to the unloading waiting area 104, the lifting drive structure 312 drives the support base 311 to fall, so as to drive the next carrying mechanism 200, realizing uninterrupted feeding action and improving the processing efficiency of the workpiece.

[0068] Conversely, at the unloading station 102, a first conveying assembly 310 is also provided. The lifting drive structure 312 at this location drives the support base 311 to rise within the unloading station 102, reaching below the unloading waiting area 104 to support the first pallet 210 transported from the feeding waiting area 103. The first pallet 210 waits in the unloading waiting area 104 for the robotic arm to place the processed workpieces onto it. Once each positioning slot 211 on the pallet 210 is filled with a workpiece, the lifting drive structure 312 drives the support base 311 to descend, causing the first pallet 210 to descend and move away from the unloading waiting area 104. The conveying mechanism 400 then transfers the second pallet 210 from the feeding waiting area 103 to the unloading waiting area 104 and stacks it on top of the first pallet 210, awaiting... After the workpieces are processed, the above actions are repeated until all the pallets 210 of a carrying mechanism 200 are transferred to the unloading waiting area 104. When the last pallet 210 in the unloading waiting area 104 also carries the processed workpieces, the lifting drive structure 312 drives the support base 311 to descend, and drives the carrying mechanism 200 to descend at the unloading station 102 to complete the unloading of the workpieces. After the unloading is completed, the support base 311 of the first conveying component 310 of the unloading station 102 should quickly move to the bottom of the unloading waiting area 104 to carry the first pallet 210 of the next group of carrying mechanisms 200. By cooperating with the handling mechanism 400 and the first conveying component 310 of the loading station 101, the uninterrupted loading and unloading of workpieces is realized, and the automated process of loading and unloading of workpieces is achieved, which improves the consistency and efficiency of production.

[0069] In an embodiment of this utility model, the material conveying mechanism 300 further includes a second conveying component 320, which includes two conveyor belts 321 spaced apart. The conveyor belts 321 are used to support the bottom of both sides of the bearing mechanism 200. The support seat 311 is located between the two conveyor belts 321 and moves up and down between the two conveyor belts 321.

[0070] Please refer to Figure 4The second conveying assembly 320 is horizontally positioned and includes a motor. The motor is connected to a transmission wheel via a transmission belt. The transmission wheel is synchronously connected to a roller, and both ends of the roller are connected to synchronous pulleys. Each synchronous pulley is wound with a conveyor belt 321, i.e., the two conveyor belts 321 are spaced apart. The horizontal dimension between the support seats 311 is smaller than the distance between the two conveyor belts 321. The conveyor belts 321 are used to convey the carrying mechanism 200. Expanding on the loading station 101, the support seat 311 of the loading station 101 is located between the two conveyor belts 321 and below the second conveying assembly 320. When the conveyor belt 321 conveys the carrying mechanism 200 to above the support seat 311, the lifting drive structure 312 drives the support seat 311 to rise, so that the entire carrying mechanism 200 rises until all the workpieces on all the pallets 210 of the carrying mechanism 200 are removed. The pallets 210 are transferred to the unloading waiting area 104. The lifting drive structure 312 then drives the support seat 311 to descend, so as to lift the next carrying mechanism 200, thus realizing continuous loading.

[0071] The unloading station 102 is the same as the loading station 101. The support base 311 of the unloading station 102 is located between two conveyor belts 321. After the support base 311 carries the carrying mechanism 200, the lifting drive structure 312 drives it to descend until the support base 311 descends below the second conveying component 320. The lowermost tray 210 of the carrying mechanism 200 falls on both sides of the conveyor belts 321. As the conveyor belts 321 rotate, the carrying mechanism 200 carrying the processed workpiece is driven away from the unloading station 102. The support base 311 of the unloading station 102 rises under the drive of the lifting drive structure 312 to carry the next set of carrying mechanisms 200, thus realizing the uninterrupted unloading action.

[0072] In an embodiment of this utility model, a plurality of carrying mechanisms 200 are carried on the conveyor belt 321. The plurality of carrying mechanisms 200 are spaced apart along the length of the conveyor belt 321. After the previous carrying mechanism 200 is lifted and transferred by the support seat 311, when the support seat 311 descends below the second conveying component 320, the conveyor belt 321 can rotate to move the next carrying mechanism 200 above the support seat 311, so as to realize continuous feeding and improve the processing efficiency of the workpiece.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
