Description

Technical Field

[0001] This application relates to the field of unmanned transport vehicle technology, and in particular to a loading and unloading device and processing equipment. Background Technology

[0002] In the process of automated production in unmanned factories, robotic arms usually move synchronously with the automated guided vehicles (AGVs) they work with, transporting materials from the AGVs to the machine tools. At the same time, the robotic arms also transport the processed materials back to the AGVs, so that the machine tools can continuously process the materials.

[0003] However, typical automated guided vehicles (AGVs) usually carry both materials awaiting processing and finished materials simultaneously. Once the robotic arm has completely removed the materials from the AGV, the AGV must wait for the robotic arm to place the finished materials onto it before the next batch of materials awaiting processing can be transported to the robotic arm. Alternatively, once the robotic arm has completely placed the finished materials onto the AGV, the AGV must wait for the robotic arm to completely remove the materials awaiting processing before it can be transported to an external storage facility. This results in excessively long waiting times for AGVs. Utility Model Content

[0004] In view of this, this application provides a loading and unloading device to solve the problem of excessively long waiting time for unmanned transport vehicles.

[0005] This application provides a loading and unloading device, including: a material transfer assembly, a second transport trolley, and two first transport trolleys. The material transfer assembly has a first storage area and a second storage area on its outer side. The two first transport trolleys are detachably connected to the material transfer assembly, with one first transport trolley located in the first storage area and the other in the second storage area. The first transport trolley in the first storage area is configured to carry materials to be processed, and the first transport trolley in the second storage area is configured to carry processed materials. Each first transport trolley is configured to move relative to the material transfer assembly and the other first transport trolley. The material transfer assembly is configured to move materials to be processed on the first transport trolleys to an external machine tool, or to move processed materials from an external processing area to the first transport trolleys. The material transfer assembly is also configured to drive the first transport trolleys in the first and second storage areas to move synchronously along the extension direction of the external processing area. The second transport trolley is configured to drive each first transport trolley to move vertically relative to the material transfer assembly, and the second transport trolley is also configured to drive each first transport trolley to move horizontally relative to the material transfer assembly and the other first transport trolley.

[0006] In the above embodiments, the first transport vehicles, which are arranged in a relatively movable manner, are used to carry the processed materials and the materials to be processed, respectively. So when one of the first transport vehicles is full of processed materials or materials to be processed, it can move relative to the transfer component and the other first transport vehicle, which helps to shorten the waiting period of the transport vehicles.

[0007] In some embodiments, the first transport vehicle includes a storage rack, the top of which is configured to support stacked materials. At least in the first storage area, the storage rack also includes multiple partitions, each partition configured to be disposed between two adjacent materials and simultaneously in contact with both adjacent materials.

[0008] In the above embodiments, the partition separates the upper and lower materials, which helps to reduce the risk of loss due to contact between the two materials.

[0009] In some embodiments, the second transport vehicle is further configured to move the first transport vehicle from within the second storage area to outside the second storage area, or to move the first transport vehicle from the first storage area to the second storage area, or to move the first transport vehicle from outside the first storage area to within the first storage area. When the transfer assembly moves the material to be processed in the first storage area, the transfer assembly is configured to synchronously move the partition below and in contact with the material to be processed. Before the transfer assembly acquires the material to be processed and transports it to the external processing area, the transfer assembly places the partition above the processed material in the second storage area.

[0010] In the above embodiments, by moving the first transport vehicle in the first storage area to the second storage area to carry the processed materials, it helps to reduce the number of times the first transport vehicle is turned over. At the same time, by moving the partition in sync with the material transfer component and moving the partition that is in contact with the material to be processed to the top of the processed material, it helps to reduce the number of steps for the material transfer component to pick up and place the partition.

[0011] In some embodiments, the first storage area and the second storage area are located on the same side of the transfer assembly.

[0012] In the above embodiments, by having the first storage area and the second storage area located on the same side of the transfer assembly, the distance the first transport vehicle moves from the first storage area to the second storage area is shortened, and the distance the transfer assembly transports the material to be processed and the partition from the first storage area to the second storage area is also shortened.

[0013] In some embodiments, the second storage area is closer to the external processing area than the first storage area, and the distance between the first transport vehicle in the second storage area and the external processing area is equal to the distance between the transfer assembly and the external processing area. The loading and unloading device also includes a drive assembly, which is at least connected to the first transport vehicle in the second storage area. The drive assembly is configured to drive the first transport vehicle to move relative to the transfer assembly to adjust the distance between the first transport vehicle and the external machine tool.

[0014] In the above embodiments, the distance that the material transfer assembly moves to transport the material to be processed is shortened. Simultaneously, the distance between the second storage area and the machine tool is adjusted to be equal to the distance between the material transfer assembly and the machine tool by the drive assembly, thereby reducing the risk of collision between the first transport vehicle in the second storage area and the machine tool.

[0015] In some embodiments, each first transport vehicle has a free end and a connecting end opposite to each other. The free end is closer to the transfer assembly than the connecting end. The connecting end of the first transport vehicle is detachably connected to the transfer assembly, and casters are provided at the bottom of the free end. The transfer assembly is also configured to provide support for the connecting end.

[0016] In the above embodiments, the connecting end is supported by the transfer component to increase the interaction force between the transfer component and the ground, thereby increasing the friction between the transfer component and the ground.

[0017] In some embodiments, each first transport vehicle further includes a first support member disposed at the connecting end and extending from the connecting end toward the transfer assembly. The transfer assembly includes a second support member configured to support the first support member and simultaneously support the connecting end.

[0018] In the above embodiments, the connecting end is supported by the second support member through the first support member, which increases the friction between the material transfer component and the ground, while helping to keep the connecting end and the free end at the same horizontal height.

[0019] In some embodiments, the first support member has a first through hole in the vertical direction. The second support member has a connecting pin, a portion of which can be located within the first through hole and contact the inner wall of the first through hole.

[0020] In the above embodiments, when the second transport vehicle drives the first transport vehicle to descend, the first support member is sleeved on the connecting pin to realize the connection between the first support member and the second support member.

[0021] In some embodiments, each first transport vehicle further includes a support leg located at the bottom of its free end. When the first transport vehicle is connected to the transfer assembly, there is a gap between the support leg and the ground. When the first transport vehicle is separated from the transfer assembly, the support leg can contact the ground and work with the casters to support the first transport vehicle.

[0022] In the above embodiment, the first transport vehicle is supported by outriggers and casters to prevent it from tipping over.

[0023] A processing apparatus includes a machine tool and a loading / unloading device as described above. The machine tool is configured to process materials and includes multiple processing stations spaced apart. The loading / unloading device is located on one side of the machine tool. A material transfer assembly is configured to move a first transport carriage along the distribution direction of the multiple processing stations and transfer materials between the processing stations and the first transport carriage. The loading / unloading device has at least two first transport carriages.

[0024] In the above embodiments, the material transfer assembly drives two first transport vehicles to move continuously, thereby transferring materials between the first transport vehicles and the machine tool and improving the automation function of the processing equipment.

[0036] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "above," "below," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0038] The terms “first”, “second”, etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implying the quantity, specific order, or primary and secondary relationship of the indicated technical features.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0040] This application provides a loading and unloading device, including: a material transfer assembly, a second transport trolley, and two first transport trolleys. The material transfer assembly has a first storage area and a second storage area on its outer side. The two first transport trolleys are detachably connected to the material transfer assembly, with one first transport trolley located in the first storage area and the other in the second storage area. The first transport trolley in the first storage area is configured to carry materials to be processed, and the first transport trolley in the second storage area is configured to carry processed materials. Each first transport trolley is configured to move relative to the material transfer assembly and the other first transport trolley. The material transfer assembly is configured to move materials to be processed on the first transport trolleys to an external machine tool, or to move processed materials from an external processing area to the first transport trolleys. The material transfer assembly is also configured to drive the first transport trolleys in the first and second storage areas to move synchronously along the extension direction of the external processing area. The second transport trolley is configured to drive each first transport trolley to move vertically relative to the material transfer assembly, and the second transport trolley is also configured to drive each first transport trolley to move horizontally relative to the material transfer assembly and the other first transport trolley.

[0041] In the above embodiments, the first transport vehicles, which are arranged in a relatively movable manner, are used to carry the processed materials and the materials to be processed, respectively. So when one of the first transport vehicles is full of processed materials or materials to be processed, it can move relative to the transfer component and the other first transport vehicle, which helps to shorten the waiting period of the transport vehicles.

[0042] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] In some embodiments, please refer to Figure 1 and Figure 2A processing device 100 includes a machine tool 10 and a loading / unloading device 20. The machine tool 10 includes a plurality of processing stations 11 arranged along a first direction X. The loading / unloading device 20 includes a material transfer assembly 21 and two first transport carts 22. The material transfer assembly 21 is disposed on one side of the machine tool 10 along a second direction Y. A first storage area 211 and a second storage area 212 are disposed on the outer side of the material transfer assembly 21. One first transport cart 22 is disposed in the first storage area 211 and the other first transport cart 22 is disposed in the second storage area 212. The first transport cart 22 in the first storage area 211 carries the material 30 to be processed. During operation, the first transport vehicle 22 of the second storage area 212 is in an unloaded state. The material transfer component 21 moves the material 30 that has been processed on one processing station 11 to the first transport vehicle 22 of the second storage area 212. The material transfer component 21 then moves the material 30 to be processed on the first transport vehicle 22 of the first storage area 211 to the processing station 11 for processing. The material transfer component 21 simultaneously drives the two first transport vehicles 22 to move to the next processing station 11, and so on, thereby realizing the function of automated processing of material 30 by the processing equipment 100.

[0044] In some embodiments, the processing equipment 100 is equipment for drilling, spraying, cutting or welding.

[0045] In some embodiments, please refer to Figure 3 The material transfer assembly 21 includes a drive vehicle 215 and a robotic arm 216 on the drive vehicle 215. The drive vehicle 215 is used to drive the robotic arm 216 and the first transport vehicle 22 to move. The robotic arm 216 can pick up or release material 30 and transfer material 30 between the processing station 11 and the first transport vehicle 22.

[0046] In some embodiments, please refer to Figure 1 The number of machine tools 10 is two or more, and the machine tools 10 are distributed sequentially along the first direction X, so that the loading and unloading device 20 can load and unload multiple machine tools 10.

[0047] In some embodiments, please refer to Figure 1 All machine tools 10 are divided into two opposing parts along the second direction Y, so that the loading and unloading device 20 can load and unload machine tools 10 on both sides of the second direction Y, which helps to improve the working efficiency of the loading and unloading device 20.

[0048] In some embodiments, the first direction X and the second direction Y are both directions on the horizontal plane, and the third direction Z is the direction of gravity upward. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0049] In some embodiments, please refer to Figure 2Each first transport vehicle 22 can be detachably connected to the material transfer component 21. The loading and unloading device 20 also includes a second transport vehicle 23, which is used to drive the first transport vehicle 22 to move up and down and move the first transport vehicle 22. When all the materials 30 in the first transport vehicle 22 in the first storage area 211 are moved to the processing station 11 by the transfer component 21, the second transport vehicle 23 drives the first transport vehicle 22 to move outward from the first storage area 211. The second transport vehicle 23 also drives another first transport vehicle 22 loaded with materials 30 to be processed to move into the first storage area 211. Alternatively, when the first transport vehicle 22 in the second storage area 212 is loaded with the processed materials 30, the second transport vehicle 23 drives the first transport vehicle 22 to move outward from the second storage area 212. The second transport vehicle 23 also drives another first transport vehicle 22, loaded with empty materials, to move into the second storage area 212. This avoids the need for the second transport vehicle 23 to simultaneously drive the first transport vehicles 22 in the first storage area 211 and the second storage area 212, and helps to shorten the time that one first transport vehicle 22 waits for the other first transport vehicle 22.

[0050] In some embodiments, there are two or more first transport vehicles 22. When a second transport vehicle 23 moves a first transport vehicle 22 in a first storage area 211 or a second storage area 212 outward, another second transport vehicle 23 moves another first transport vehicle 22 into the first storage area 211 or the second storage area 212.

[0051] In some embodiments, the number of second transport vehicles 23 is two or more, such that one second transport vehicle 23 drives one first transport vehicle 22 to move to or from the first storage area 211, and another second transport vehicle 23 drives another first transport vehicle 22 to move to or from the second storage area 212.

[0052] In some embodiments, the second transport vehicle 23 is part of the processing equipment 100.

[0053] In some embodiments, since the material transfer component 21 needs to move the processed material 30 from the processing station 11 to the first transport vehicle 22 in the second storage area 212 before the processing station 11 becomes available to accommodate the material 30 to be processed, the time it takes for the first transport vehicle 22 in the second storage area 212 to reach full load is faster than the time it takes for the first transport vehicle 22 in the first storage area 211 to reach empty load. Therefore, the second transport vehicle 23 can first move the fully loaded first transport vehicle 22 in the second storage area 212 outward, and then move the empty first transport vehicle 22 in the first storage area 211 to the second storage area 212, thereby helping to improve the efficiency of the second transport vehicle 23 in moving the first transport vehicle 22.

[0054] In some embodiments, please refer to Figure 4 and Figure 5 All of the first transport vehicles 22 include a storage rack 221, on which multiple materials 30 are stacked and stored, so that the first transport vehicle 22 can carry multiple materials 30 at the same time.

[0055] In some embodiments, please refer to Figure 6 The first transport vehicle 22 of the first storage area 211 also includes a partition 301. Each partition 301 is respectively disposed between two adjacent materials 30 and contacts the two materials 30 respectively, so as to isolate the two adjacent materials 30 from each other, thereby avoiding the risk of damage caused by the materials 30 contacting each other.

[0056] For example, please refer to Figure 7 Material 30 is a PCB board 31. A ejector pin 32 is provided at the bottom of the PCB board 31. When the PCB board 31 is placed in the processing station 11, the ejector pin 32 embeds into the machine tool 10 to fix the PCB board 31. The partition plate 301 is configured to contact the ejector pins 32 of the PCB board 31 above it, thus supporting the PCB board 31 while preventing the ejector pins 32 of the upper PCB board 31 from contacting the ejector pins 32 of the lower PCB board 31, which could cause damage to the lower PCB board 31.

[0057] In some embodiments, when the transfer assembly 21 moves the material 30 to be processed in the first storage area 211 to the processing station 11, the transfer assembly 21 first synchronously moves the first partition 301 below the material 30 to be processed (i.e., the partition 301 in contact with the material 30) to the second storage area 212. After the transfer assembly 21 places the partition 301 above the processed material 30 in the second storage area 212, the transfer assembly 21 then moves the material 30 to be processed from the second storage area 212 to the processing station 11. Finally, the transfer assembly 21 moves another material to be processed... The processed material 30 at workstation 11 is placed above the partition 301 of the second storage area 212. This avoids the need for the material transfer component 21 to move the partition 301 of the first storage area 211 to the outside of the first storage area 211 and the second storage area 212 before moving the material 30 to be processed, and also avoids the need for the material transfer component 21 to move the partition 301 outside the second storage area 212 to the top of the material 30 in the second storage area 212 before moving the processed material 30. This helps to reduce the steps of the material transfer component 21 moving the partition 301 alone.

[0058] In some embodiments, the first storage area 211 and the second storage area 212 are located on the same side of the transfer assembly 21 to shorten the distance the first transport vehicle 22 moves from the first storage area 211 to the second storage area 212, and to shorten the distance the transfer assembly 21 transports the material 30 to be processed and the partition 301 from the first storage area 211 to the second storage area 212.

[0059] In some embodiments, the first storage area 211 and the second storage area 212 are located on one side of the transfer assembly 21 along the first direction X, and the second storage area 212 is closer to the machine tool 10 relative to the first storage area 211, so that the first storage area 211, the second storage area 212 and the processing station 11 can be distributed sequentially along the first direction X. This helps the robotic arm 216 of the transfer assembly 21 to always move unidirectionally along the first direction X during the process of moving the material to be processed 30 and the processed material 30, so as to improve the efficiency of loading and unloading of the robotic arm 216.

[0060] In some embodiments, when the second storage area 212 is closer to the machine tool 10 relative to the first storage area 211, the distance between the first transport vehicle 22 in the second storage area 212 and the machine tool 10 is equal to the distance between the transfer assembly 21 and the machine tool 10, so as to reduce the risk of the first transport vehicle 22 in the second storage area 212 colliding with the machine tool 10 or the outside world during the process of the transfer assembly 21 driving the first transport vehicle 22 to move.

[0061] In some embodiments, the storage racks 221 of the first transport vehicle 22 each have a free end 222 and a connecting end 223. The free end 222 is closer to the transfer assembly 21 than the connecting end 223. When the second transport vehicle 23 moves the first transport vehicle 22 closer to the transfer assembly 21, the connecting end 223 connects to the transfer assembly 21. Alternatively, when the second transport vehicle 23 moves the first transport vehicle 22 away from the transfer assembly 21, the connecting end 223 separates from the transfer assembly 21. The detachable connection between the connecting end 223 and the transfer assembly 21 allows the first transport vehicle 22 to move relative to the transfer assembly 21, or the transfer assembly 21 to synchronously move the first transport vehicle 22.

[0062] In some embodiments, please refer to Figure 4 and Figure 5 The bottom of the free end 222 is equipped with casters 224. When the first transport vehicle 22 is connected to the transfer component 21, the connecting end 223 is mounted on the transfer component 21 so that the transfer component 21 supports the connecting end 223, thereby increasing the force between the transfer component 21 and the ground and increasing the friction between the transfer component 21 and the ground. This helps to reduce the risk of slippage between the transfer component 21 and the ground when the transfer component 21 drives the two first transport vehicles 22 to move synchronously.

[0063] In some embodiments, please refer to Figure 4 and Figure 5 The bottom of the connecting end 223 is provided with a support leg 225. When the first transport vehicle 22 is separated from the transfer assembly 21 and the second transport vehicle 23 does not move the first transport vehicle 22, the support leg 225 and the caster 224 jointly support the storage rack 221, thereby keeping the top of the storage rack 221 at a certain level and reducing the risk of the storage rack 221 tipping over.

[0064] It is understandable that when the first transport vehicle 22 is connected to the transfer assembly 21, there is a gap between the support leg 225 and the ground so that the transfer assembly 21 can synchronously drive the first transport vehicle 22 to move.

[0065] In addition, when the second transport vehicle 23 moves the first transport vehicle 22, the second transport vehicle 23 drives the first transport vehicle 22 to rise as a whole, so that the support legs 225 are away from the ground, thereby avoiding friction between the support legs 225 and the ground. At the same time, it helps to keep the top of the storage rack 221 in a horizontal state, so as to reduce the risk of the material 30 on the top of the storage rack 221 slipping off.

[0066] For example, when the second transport vehicle 23 moves the first transport vehicle 22, the distance between the support leg 225 and the ground is less than the radius of the caster 224, so that when the support leg 225 and the caster 224 jointly support the storage rack 221, it helps to reduce the angle between the top of the storage rack 221 and the horizontal plane.

[0067] In some embodiments, please refer to Figure 4 and Figure 5 The second transport vehicle 23 is equipped with a lifting block 231 on its top and a base plate 227 on its bottom. Before the second transport vehicle 23 moves the first transport vehicle 22, the second transport vehicle 23 moves to the bottom of the first transport vehicle 22 and aligns the lifting block 231 with the base plate 227. The lifting block 231 is then raised to support the base plate 227 by the lifting drive mechanism (not shown) inside the second transport vehicle 23, and the base plate 227 is raised in sync with the overall height of the storage rack 221, thereby achieving the effect of the second transport vehicle 23 driving the first transport vehicle 22 to lift.

[0068] In some embodiments, please refer to Figure 5 The top of the lifting block 231 is provided with a positioning pin 2311, and the bottom surface of the base plate 227 is provided with a positioning hole (not marked). When the lifting block 231 approaches the base plate 227, part of the positioning pin 2311 is inserted into the positioning hole to position the base plate 227, thereby reducing the risk of the storage rack 221 sliding relative to the second transport vehicle 23.

[0069] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 8 The first transport vehicle 22 also includes a first support member 226, which is located at the connecting end 223 and extends from the connecting end 223 toward the transfer assembly 21. The transfer assembly 21 includes a second support member 213, which is respectively located on the side of the drive vehicle 215 facing the first storage area 211 and the second storage area 212. When the first transport vehicle 22 is connected to the transfer assembly 21, the first support member 226 rests on top of the second support member 213, so that the second support member 213 supports the first support member 226 and simultaneously supports the connecting end 223, thereby ensuring that the transfer assembly 21 always provides support to the first transport vehicle 22.

[0070] In some embodiments, please refer to Figure 5 and Figure 8The first support member 226 has a first through hole 2261 along the vertical direction, and the top of the second support member 213 has a connecting pin 2131. When the second transport vehicle 23 moves the first transport vehicle 22 to the first storage area 211 or the second storage area 212, the first through hole 2261 and the first connecting pin 2131 are arranged vertically opposite each other. The second transport vehicle 23 drives the first transport vehicle 22 to descend as a whole, and the first support member 226 is sleeved on the connecting pin 2131 so that part of the connecting pin 2131 is located in the first through hole 2261. When the second transport vehicle 23 moves the first transport vehicle 22 outward from the first storage area 211 or the second storage area 212, the second transport vehicle 23 drives the first transport vehicle 22 to rise as a whole, the first support member 226 separates from the second support member 213, and the connecting pin 2131 moves out of the first through hole 2261, thereby realizing the connection between the first transport vehicle 22 and the material transfer assembly 21. It should be noted that when the material transfer assembly 21 moves, it contacts the inner wall of the first through hole 2261 through the connecting pin 2131, so as to realize that the material transfer assembly 21 synchronously drives the first transport vehicle 22 to move.

[0071] In other embodiments, both the first transport vehicle 22 and the drive vehicle 215 of the transfer assembly 21 are provided with a locking structure, which can also enable the first transport vehicle 22 and the transfer assembly 21 to be detachably connected.

[0072] In some embodiments, the locking structure, the first through hole 2261, and the connecting pin 2131 coexist. The first through hole 2261 and the connecting pin 2131 cooperate to pre-position the locking structure of the first transport vehicle 22 and the material transfer assembly 21.

[0073] In some embodiments, please refer to Figure 8 The loading and unloading device 20 also includes a drive assembly 214, which is at least connected to the first transport vehicle 22 in the second storage area 212. The drive assembly 214 is configured to drive the first transport vehicle 22 to move relative to the material transfer assembly 21 in the second direction Y to adjust the distance between the first transport vehicle 22 and the machine tool 10, thereby avoiding the risk of collision between the first transport vehicle 22 or transport vehicles of different sizes moving from the first storage area 211 to the second storage area 212 and the machine tool 10.

[0074] In some embodiments, when the first transport vehicle 22 is able to move relative to the transfer assembly 21 in the second direction Y, the caster 224 is a swivel wheel.

[0075] In some embodiments, please refer to Figure 8The drive assembly 214 includes a cylinder (not labeled), which is mounted on the drive carriage 215 of the transfer assembly 21. A slider 2132 is mounted on the top of the second support member 213, and the slider 2132 is slidably connected to the second support member 213 and slides relative to the second support member 213 along the second direction Y. A connecting pin 2131 is mounted on the top of the slider 2132, and the telescopic end of the cylinder is connected to the slider 2132. When it is necessary to adjust the distance between the first transport carriage 22 and the machine tool 10, the cylinder drives the slider 2132 to move relative to the drive carriage 215 of the transfer assembly 21 along the second direction Y, and synchronously drives the first transport carriage 22 to move through the first support member 226, thereby realizing the drive assembly 214 driving the first transport carriage 22 to adjust its position.

[0076] In some embodiments, the cylinder is disposed on the second support member 213.

[0077] In some embodiments, please refer to Figure 5 There are at least two first support members 226, each of which is provided with a first through hole 2261. The corresponding second support member 213 is provided with the same number of connecting pins 2131 as the first through holes 2261. The connecting pins 2131 are engaged one by one by the at least two first through holes 2261 to reduce the risk of the first transport vehicle 22 rotating around the connecting pins 2131 when the drive assembly 214 drives the first transport vehicle 22 to adjust its position.

[0078] In other embodiments, the number of first through holes 2261 on the first support member 226 is multiple.

[0079] In other embodiments, the position of the first transport vehicle 22 in the second direction Y can also be adjusted by an external mechanism. For example, the processing equipment 100 also includes a third transport vehicle, the structure of which is the same as that of the second transport vehicle 23.

[0080] In some embodiments, please refer to Figure 3 The top of the drive vehicle 215 is equipped with a scanning component 217. When the robotic arm 216 transports the PCB board 31, the robotic arm 216 drives the ejector pins 32 on the PCB board 31 to move through the scanning area of ​​the scanning component 217, so that the scanning component 217 can identify the position of the ejector pins 32 and send a feedback signal to the robotic arm 216, so that the robotic arm 216 can rotate the PCB board 31. This makes it easier for the robotic arm 216 to place the PCB board 31 in the first transport vehicle 22 of the second storage area 212 or the processing station 11, thereby improving the accuracy of contact between the ejector pins 32 on the PCB board 31 and the partition 301 on the first transport vehicle 22 or the designated position on the processing station 11.

[0081] In some embodiments, the scanning component 217 is a CDD camera.

[0082] In some embodiments, the scanning component 217 is located on the side of the drive vehicle 215 near the first storage area 211 and the second storage area 212.

[0083] In other embodiments, please refer to Figure 9 The first storage area 211 and the second storage area 212 are located on opposite sides of the transfer assembly 21 in the second direction Y, with the two first transport vehicles 22 located on opposite sides of the transfer assembly 21, thereby helping to reduce the width of the loading and unloading device 20 in the first direction X when the transfer assembly 21 moves the two first transport vehicles 22.

[0084] Meanwhile, when the material transfer assembly 21 simultaneously supports the first transport vehicle 22 in the first storage area 211 and the second storage area 212, the symmetrical arrangement of the two first transport vehicles 22 helps to improve the balance of the material transfer assembly 21.

[0085] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the substantive scope of this application fall within the scope of this application.
