Description

Technical Field

[0001] This utility model relates to the field of vehicle transfer technology, and in particular to a feeding mechanism and a cleaning device. Background Technology

[0002] In microelectronics and semiconductor manufacturing, carriers are used to transport photoresist containers from warehouses to cleanrooms. However, since the carriers inevitably pick up dust and other impurities during the transfer process, it is necessary to clean the outer surface of the carriers to prevent them from carrying dust and other impurities into the cleanroom.

[0003] Currently, existing cleaning devices require manual placement of the carrier from the AGV transfer vehicle into the cleaning device for cleaning, rather than automatically lifting the carrier from the AGV transfer vehicle and sending it into the cleaning device for cleaning. Utility Model Content

[0004] The main purpose of this utility model is to propose a feeding mechanism and a cleaning device, which aims to solve the problem that existing cleaning devices cannot be used in conjunction with AGV transfer vehicles to achieve automatic loading and unloading.

[0005] To achieve the above objectives, this utility model proposes a feeding mechanism for use in a cleaning device, comprising:

[0006] A loading frame, one end of which has a clearance space for parking the transfer vehicle of the transfer vehicle;

[0007] The lifting assembly is mounted on the loading frame;

[0008] A conveying component is disposed on the lifting component, and the lifting component is drivenly connected to the conveying component to drive the conveying component to move up and down between a first position and a second position, wherein the second position is located above the first position;

[0009] At the first position, the conveying assembly is used to support the vehicle on the transfer vehicle located within the clearance space;

[0010] In the second position, the conveying assembly is used to convey the carrier carried thereon to the conveying mechanism of the cleaning device.

[0011] In one embodiment, the loading frame includes a body and a mounting portion, the mounting portion being located above the body, and a portion of the mounting portion protruding from the body to form the clearance space, so that the transfer vehicle can park and transfer the loaded vehicle to the top of the mounting portion.

The support portion is placed on the loading frame and connected to the lifting assembly. The first conveying portion and the second conveying portion are sequentially arranged on top of the support portion along the conveying direction.

[0013] In one embodiment, the conveying assembly further includes a weighing module disposed on the first conveying section and / or the second conveying section for weighing the vehicle located above the first conveying section or the second conveying section.

[0014] In one embodiment, the conveying assembly is provided with guide components on both sides perpendicular to its own conveying direction. The guide components include a connecting frame and a guide wheel. The connecting frame is detachably mounted on the conveying assembly, and the guide wheel is rotatably mounted on the end of the connecting frame away from the conveying assembly. The guide surface of the guide wheel is set towards the conveying assembly.

[0015] In one embodiment, the conveying assembly is provided with braking assemblies at both ends along the direction of conveying the vehicle. The braking assembly includes a telescopic cylinder and a telescopic column. The telescopic column is vertically and flexibly disposed in the telescopic cylinder along the lifting direction of the conveying assembly. When the telescopic column extends out of the telescopic cylinder, the telescopic column can prevent the vehicle from slipping off the conveying assembly.

[0016] In one embodiment, the braking assembly further includes a buffer block disposed at the end of the telescopic column facing away from the telescopic cylinder.

[0017] In one embodiment, the conveying assembly includes an assembly frame, a plurality of trays, and a plurality of motorized rollers.

[0018] In one embodiment, the lifting assembly includes a power unit, a first drive unit, a second drive unit, and a linkage unit. The first drive unit and the second drive unit are spaced apart along the direction in which the conveying assembly transports the carrier. The linkage unit is located between the first drive unit and the second drive unit and is connected to both the first drive unit and the second drive unit. The linkage unit is connected to the power unit, and the power unit is used to drive the linkage unit to lift the first drive unit and the second drive unit.

[0019] This utility model also proposes a cleaning device, including a cleaning mechanism, a conveying mechanism, and a feeding mechanism as described in the above embodiments.

[0020] The technical solution of this utility model enables the cleaning device for cleaning vehicles to be automatically transported into the cleaning device by a feeding mechanism in conjunction with a transfer vehicle for vehicle transportation.

[0034] Currently, existing cleaning devices require manual placement of the carrier from the AGV transfer vehicle into the cleaning device for cleaning, rather than automatically lifting the carrier from the AGV transfer vehicle and sending it into the cleaning device for cleaning.

[0035] This utility model proposes a feeding mechanism.

[0036] Please see Figures 1 to 3In one embodiment of this utility model, the feeding mechanism 10 is applied to the cleaning device 100, including a feeding frame 11, a lifting assembly 13, and a conveying assembly 12. One end of the feeding frame 11 has a clearance space 113 for parking a transfer vehicle of a transfer vehicle. The lifting assembly 13 is disposed on the feeding frame 11. The conveying assembly 12 is disposed on the lifting assembly 13. The lifting assembly 13 and the conveying assembly 12 are drivenly connected to drive the conveying assembly 12 to move up and down between a first position and a second position, the second position being above the first position. In the first position, the conveying assembly 12 is used to support the vehicle on the transfer vehicle located in the clearance space 113. In the second position, the conveying assembly 12 is used to convey the vehicle carried thereon to the conveying mechanism of the cleaning device 100.

[0037] The technical solution of this utility model involves providing a clearance space 113 at one end of the loading frame 11. This clearance space 113 is used for a transfer vehicle to stop below the loading frame 11 and transfer the transported vehicle to above the conveying assembly 12. In this embodiment, the transfer vehicle is slightly lower than the height of the clearance space 113, but the width of the transfer vehicle is greater than the width of the loading frame 11. The vehicle is transferred by standing on the transfer vehicle, and the width of the vehicle is also greater than the width of the loading mechanism 10. When the vehicle is standing on the transfer vehicle for transfer, the vehicle is higher than the conveying assembly 12 set on the loading frame 11. Therefore, when the transfer vehicle transfers the vehicle, it can stop in the clearance space 113. At this time, the vehicle is located above the conveying assembly 12. Since the loading frame 11 is provided with a lifting assembly 13 that can raise and lower the conveying assembly 12, the lifting assembly 13 can drive the conveying assembly 12 to rise and fall, so that the conveying assembly 12 has a first position and a second position. The second position is located above the first position. When the conveying assembly 12 is in the first position, this... When the conveying component 12 is in a state of preparing to support the vehicle, and the transfer vehicle transports the vehicle to a position above the conveying component 12 in the first position, the lifting component 13 is activated, driving the conveying component 12 to lift from the first position to the second position. When the conveying component 12 is lifted, it supports the bottom of the vehicle and removes the vehicle from the transfer vehicle. At this time, the transfer vehicle can move out of the clearance space 113. Then, the conveying component 12 transports the vehicle to the conveying mechanism of the cleaning device 100, so that the vehicle can be cleaned in a production line manner within the cleaning device 100 through the conveying mechanism. With this setting, the cleaning device 100 used for cleaning the vehicle can automatically transport the vehicle into the cleaning device 100 through the loading mechanism 10 in conjunction with the transfer vehicle for transporting the vehicle, thereby realizing a production line cleaning operation within the cleaning device 100, and further improving the automation effect of the cleaning device 100, reducing the use of manual labor, and improving the working efficiency of the cleaning device 100.

[0038] In one embodiment, such as Figure 1 and Figure 2 As shown, the loading frame 11 includes a body part 111 and a mounting part 112. The mounting part 112 is located above the body part 111. Part of the mounting part 112 protrudes from the body part 111 to form the clearance space 113, so that the transfer vehicle can park and transfer the loaded vehicle to the top of the mounting part 112. In this embodiment, the loading frame 11 includes a main body 111 and a mounting part 112, wherein the mounting part 112 is located above the main body 111, and a portion of the mounting part 112 protrudes from the main body 111. The protruding portion of the mounting part 112 and the main body 111 form a clearance space 113 as described in the above embodiment, which is used for parking the transfer vehicle of the transfer vehicle, so that the loading mechanism 10 can easily transfer and transport the vehicle. Of course, in other embodiments, the main body 111 and the mounting part 112 can be integrally formed, or they can be installed later in a detachable manner. The mounting part 112 can also be formed by the end of the main body 111 away from the ground protruding outward. The specific configuration of the main body 111 and the mounting part 112 is not limited in much.

[0039] In one embodiment, such as Figure 1 and Figure 3 As shown, the conveying assembly 12 includes a support part 121, a first conveying part 122, and a second conveying part 123. The support part 121 is placed on the loading frame 11 and connected to the lifting assembly 13. The first conveying part 122 and the second conveying part 123 are arranged sequentially on the top of the support part 121 along the conveying direction. To facilitate the assembly and installation of the conveying assembly 12, in this embodiment, the conveying assembly 12 includes a support portion 121, a first conveying portion 122, and a second conveying portion 123. The first conveying portion 122 and the second conveying portion 123 are rotatably disposed above the support portion 121. The support portion 121 is connected to the lifting end of the lifting assembly 13. When the conveying assembly 12 is in the first position, the support portion 121 supports the loading frame 11. The support portion 121 can use the loading frame 11 as a support portion. In some embodiments, the first conveying portion 122 and the second conveying portion 123 can be independent conveying systems or interconnected conveying systems. No further limitations are imposed on this. The arrangement of the first conveying portion 122 and the second conveying portion 123 not only facilitates installation but also facilitates inspection and maintenance.

[0040] Specifically, such as Figure 3As shown, the conveying assembly 12 further includes a weighing module 16, which is disposed on the first conveying section 122 and / or the second conveying section 123 for weighing the vehicle located above the first conveying section 122 or the second conveying section 123. To obtain specific information about the carrier, in this embodiment, a weighing module 16 is provided on the first conveying section 122 or the second conveying section 123. When the carrier is supported by the first conveying section 122 or the second conveying section 123, the weighing module 16 can weigh the carrier. The weighing result determines whether the carrier is carrying a workpiece. If no workpiece is loaded, the cleaning device 100 will activate the flipping mechanism 50 to flip the carrier and clean it thoroughly. If a workpiece is loaded, the cleaning device 100 will not activate the flipping mechanism 50 and will only clean the bottom and outer perimeter of the carrier. This setting allows for a more specific understanding of the carrier's condition. To improve the accuracy of the weighing results, in one embodiment, a weighing module 16 is provided on both the first conveying section 122 and the second conveying section 123. The two weighing modules 16 can cross-check the weight of the carrier, making the results more accurate. Of course, in other embodiments, the weighing module 16 can be replaced by other acoustic and optical sensors, or the weighing module 16 can be used in conjunction with an acoustic and optical sensor. No further limitations are imposed on this.

[0041] In one embodiment, such as Figure 1 As shown, the conveying assembly 12 is provided with guide assemblies 14 on both sides perpendicular to its own conveying direction. The guide assembly 14 includes a connecting frame 141 and a guide wheel 142. The connecting frame 141 is detachably mounted on the conveying assembly 12, and the guide wheel 142 is rotatably mounted on the end of the connecting frame 141 away from the conveying assembly 12. The guide surface of the guide wheel 142 is set towards the conveying assembly 12. To prevent the conveying assembly 12 from deviating from the preset conveying direction when conveying the vehicle, in this embodiment, guide assemblies 14 are provided on both sides perpendicular to the conveying direction of the conveying assembly 12. Each guide assembly 14 includes a connecting frame 141 and guide wheels 142. The guide wheels 142 are rotatably mounted on the connecting frame 141, and the guide surface of the guide wheels 142 faces the conveying assembly 12. The connecting frame 141 is detachably mounted on both sides of the conveying assembly 12. In this embodiment, multiple guide assemblies 14 are provided, and the multiple guide assemblies 14 are spaced apart along the conveying direction of the conveying assembly 12. When the conveying assembly 12 conveys the vehicle, the guide assemblies 14 can abut against the bottom of the vehicle and roll in connection with the bottom of the vehicle through the guide wheels 142 to guide the conveying direction of the vehicle.

[0042] In one embodiment, such as Figure 1As shown, the conveying assembly 12 is provided with braking assemblies 15 at both ends along the direction of conveying the vehicle. The braking assembly 15 includes a telescopic cylinder 151 and a telescopic column 152. The telescopic column 152 is vertically and vertically disposed in the telescopic cylinder 151 along the lifting direction of the conveying assembly 12. When the telescopic column 152 extends out of the telescopic cylinder 151, the telescopic column 152 can prevent the vehicle from slipping off the conveying assembly 12. To prevent the carrier from slipping off the conveying assembly 12 and being damaged when it is being conveyed, a braking assembly 15 is also provided in this embodiment. The braking assembly 15 is set at both ends of the loading frame 11 along the conveying direction of the conveying assembly 12. When the conveying assembly 12 is raised from the first position to the second position, the telescopic cylinder 151 in the braking assembly 15 will push the telescopic column 152 to extend outward until it protrudes out of the telescopic cylinder 151 and the conveying assembly 12, so as to protect the carrier on the conveying assembly 12. The braking assembly 15 can also control the rhythm of the carrier entering the cleaning device 100 to prevent multiple carriers from entering the cleaning device 100 at the same time, causing cleaning congestion and resulting in low cleaning efficiency.

[0043] Specifically, the braking assembly 15 further includes a buffer block 153, which is disposed at the end of the telescopic column 152 facing away from the telescopic cylinder 151. To prevent the telescopic column 152 from damaging the vehicle, in this embodiment, a buffer block 153 is also provided at the end of the telescopic column 152 extending out of the telescopic cylinder 151. The buffer block 153 is made of flexible material, which can prevent the vehicle from being bumped and damaged when it comes into contact with the vehicle. Of course, in other embodiments, the buffer block 153 can also be a buffer sleeve, which is sleeved on the outer periphery of the telescopic column 152. The specific setting of the buffer block 153 is not limited in much.

[0044] In one embodiment, the conveying assembly 12 includes an assembly frame, multiple trays, and multiple electric rollers. The trays and electric rollers are rotatably disposed within the assembly frame, and are staggered along the conveying direction of the carrier. To save manufacturing costs, in this embodiment, the conveying assembly 12 includes an assembly frame, multiple trays, and multiple electric rollers. The trays and electric rollers are rotatably disposed within the assembly frame, and are staggered along the conveying direction of the conveying assembly 12. This reduces the use of electric rollers, which means reducing the use of drive motors, while still achieving good conveying performance. In embodiments where the conveying assembly 12 includes a first conveying section 122 and a second conveying section 123, both the first conveying section 122 and the second conveying section 123 can be arranged in this manner.

[0045] In one embodiment, such as Figure 3 As shown, the lifting assembly 13 includes a power unit 131, a first drive unit 132, a second drive unit 133, and a linkage unit 134. The first drive unit 132 and the second drive unit 133 are spaced apart along the direction of the conveying assembly 12 for conveying the carrier. The linkage unit 134 is located between the first drive unit 132 and the second drive unit 133 and is linked to both the first drive unit 132 and the second drive unit 133. The linkage unit 134 is linked to the power unit 131. The power unit 131 is used to drive the linkage unit 134 to lift the first drive unit 132 and the second drive unit 133. Because the conveying assembly 12 is relatively long, it needs to protrude from the main body 111, similar to the mounting portion 112 in the aforementioned lifting frame. The lifting assembly 13 is installed inside the main body 111. To enhance the support of the lifting assembly 13 for the conveying assembly 12, in this embodiment, the lifting assembly 13 includes a power unit 131, a first drive unit 132, a second drive unit 133, and a linkage unit 134. One end of the first drive unit 132 and the second drive unit 133 are connected to the bottom of the conveying assembly 12. The first drive unit 132 and the second drive unit 133 are spaced apart along the conveying direction of the conveying assembly 12. The linkage unit 134 is located between the first drive unit 132 and the second drive unit 133 and engages with them respectively. The linkage unit 134 is located within the main body of the lifting frame. The power unit 131 inside 111 is linked. In this embodiment, the power unit 131 is a drive motor, the linkage 134 is a transmission rod, and the first drive unit 132 and the second drive unit 133 are lifting rods. They are all connected by meshing transmission. In another embodiment, there are multiple first drive units 132 and multiple second drive units 133. Another transmission rod can be set between the multiple first drive units 132 and multiple second drive units 133 so that the multiple first drive units 132 and multiple second drive units 133 can realize lifting operations synchronously. The lifting assembly 13 configured in this way can maintain a stable lifting operation of the conveying assembly 12. In other embodiments, the lifting assembly 13 can use a hydraulic lifting system or a pneumatic lifting system instead of the above-mentioned transmission system. The specific configuration of the lifting assembly 13 is not limited.

[0046] This utility model also proposes a cleaning device 100, which includes a cleaning mechanism, a conveying mechanism, and a loading mechanism 10 as described in the above embodiments. The specific structure of the loading mechanism 10 is as described in the above embodiments. Since this cleaning device 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The cleaning device 100 also includes a flipping mechanism 50 and a blowing mechanism 60. In the embodiments of this utility model, there are two loading mechanisms 10, which are respectively arranged at both ends of the conveying mechanism. The clearance space 113 formed by the two loading mechanisms 10 faces opposite directions. One of the two loading mechanisms 10 can be used to load materials onto the carrier in conjunction with the transfer vehicle, and the other can be used to unload materials from the carrier in conjunction with the transfer vehicle.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. 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 patent protection scope of the present utility model.
