Description

Technical Field

[0001] This utility model relates to the technical field of AGV (Automated Guided Vehicle) vehicle repair equipment, specifically a tooling for replacing the drive unit of an integrated AGV vehicle. Background Technology

[0002] In the solar cell production process, baskets containing silicon wafers need to be moved from one process to the next. In today's highly automated world, AGVs have replaced manual handling. During the operation of an integrated LiDAR AGV, the drive unit may inevitably malfunction, preventing the vehicle from moving normally. In this case, the drive unit needs to be removed for repair or replaced with a new one.

[0003] Currently, most drive unit replacement tools only use jacks and wrenches. The jack lifts one side of the AGV, the wrench removes the screws securing the drive unit, and then the new drive unit is installed. This method requires two people: one to loosen the screws and the other to lift the AGV. The AGV is heavy, making lifting difficult and increasing the risk of injury to workers. Furthermore, for workshops with hundreds of AGVs, disassembling and assembling drive units is both laborious and unsafe. Therefore, the battery manufacturing industry urgently needs a labor-saving and safe disassembly and assembly tool.

[0004] Therefore, a tooling for replacing the drive unit of an integrated AGV is proposed to address the above problems. Utility Model Content

[0007] Preferably, each of the hollow plates is connected to a pair of fixing knobs by threads. The fixing knobs consist of a pressing part and a rotating part, and the rotating part has multiple anti-slip grooves on its outer side.

[0008] Preferably, each of the pair of brackets has a track plate fixedly connected to its top surface, and each of the pair of track plates has a track groove on one side that is close to each other. A sliding plate is slidably connected inside each track groove, and a retractable first receiving plate is provided above the sliding plate. The surface of the first receiving plate has a plurality of first receiving grooves.

[0009] Preferably, a rotating sleeve is rotatably connected to the top surface of the sliding plate, and an adjusting column is threadedly connected inside the rotating sleeve. The top surface of the adjusting column is fixedly connected to the bottom surface of the first receiving plate.

[0010] Preferably, a limiting block is fixedly connected to one side of each pair of sliding plates that are close to each other. The limiting block has a sliding hole inside, and a limiting slide rod is slidably connected inside the sliding hole. The top surface of the limiting slide rod is fixedly connected to the bottom surface of the first receiving plate.

[0011] Preferably, each of the pair of limiting blocks is fixedly connected to a connecting rod on the side that is close to each other, and each of the pair of connecting rods is slidably connected to a gripping rod on the side that is close to each other.

[0012] Preferably, the gripping rod is hollow, and the surface of the gripping rod has multiple annular grooves.

[0016] The advantages of this utility model are: 1. The tooling for replacing the drive unit of an integrated AGV trolley described in this utility model involves placing a hydraulic jack under the load-bearing beam of the AGV trolley and then activating the hydraulic jack to lift the AGV trolley, as shown in the figure. At this time, the drive unit of the AGV trolley that needs to be replaced will be lifted by the hydraulic jack, and the employee can then carry out the replacement or repair work. In this way, only one person is needed to complete the repair or replacement of the AGV trolley drive unit, which improves the work efficiency. At the same time, using a hydraulic jack to lift the AGV trolley is also safer.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] like Figures 1 to 8 As shown, a tooling for replacing the drive unit of an integrated AGV trolley includes a pair of brackets 1, hollow plates 3 are fixedly connected to the side of the pair of brackets 1 that are close to each other, a limiting slide plate 4 is slidably connected between the pair of hollow plates 3, and hydraulic jacks 2 are fixedly connected inside the pair of brackets 1 and to the side of the pair of brackets that are close to the hollow plates 3. During operation, it is understood that the hydraulic jack 2 is existing technology, and its related principles will not be elaborated upon in this utility model. When the drive unit of the AGV trolley malfunctions and needs to be replaced, first move this fixture to the AGV trolley, and then push it in the direction of the hydraulic jack 2 until it is located below the load-bearing beam of the AGV trolley. It should be noted that before pushing the fixture, its position needs to be adjusted so that the hydraulic jack 2 is aligned with the load-bearing beam of the AGV trolley, and the pushing direction is the direction of the drive unit that needs to be replaced on the AGV trolley. After the hydraulic jack 2 is located below the load-bearing beam of the AGV trolley, activate the hydraulic jack 2 to lift the AGV trolley, as shown in the specific state. Figure 6 As shown, the drive unit of the AGV that needs to be replaced will be lifted by hydraulic jack 2, allowing the employee to perform the replacement or repair work. This way, only one person is needed to complete the repair or replacement of the AGV drive unit, improving work efficiency. Using hydraulic jack 2 to lift the AGV is also safer. It should be noted that because AGV models and sizes vary, the width of the load-bearing beams differs. To improve the applicability of this tooling, a hollow plate 3 and a limiting slide plate 4 are designed. Before use, the distance between a pair of hydraulic jacks 2 can be manually adjusted according to the size of the AGV. The specific adjustment method is to reduce the distance between the pair of hydraulic jacks 2. Taking the distance as an example, the employee first holds one side of the bracket 1 to prevent it from moving, and then presses the other side of the bracket 1 to apply pressure. This pressure will act on the hollow plate 3 and the limiting slide plate 4, so that the limiting slide plate 4 slides inside the hollow plate 3. That is, the limiting slide plate 4 will be retracted into the hollow plate 3. In this way, the distance between the pair of brackets 1 will be reduced, thereby reducing the distance between the pair of hydraulic jacks 2. Similarly, when it is necessary to increase the distance between the pair of hydraulic jacks 2, it is only necessary to apply a pulling force to the other side of the bracket 1. In this way, the distance between the pair of hydraulic jacks 2 can be freely adjusted according to the AGV car model, adapting to more models of AGV cars and improving the applicability of this tooling. It should be noted that the drive unit of the AGV is the wheel in the traditional sense.

[0022] Each pair of hollow plates 3 is externally connected to a pair of fixing knobs 5 by threads. Each fixing knob 5 consists of a pressing part and a rotating part. Multiple anti-slip grooves are provided on the outer side of the rotating part. During operation, after the distance between the pair of hydraulic jacks 2 is adjusted, to prevent the hollow plate 3 from sliding against the limiting slide plate 4 during subsequent use, which would cause the distance between the hydraulic jacks 2 to change and thus fail to effectively support the AGV trolley, a fixing knob 5 is designed. The pressing part of the fixing knob 5 is a traditional bolt, while its rotating part is a cylindrical handle with multiple anti-slip grooves to prevent the handle from slipping off. In actual use, the employee only needs to hold the rotating part of the fixing knob 5 and turn it to drive the pressing part to rotate. At this time, the pressing part will slide into the hollow plate 3 and gradually come into contact with the limiting slide plate 4, thus pressing the limiting slide plate 4. After being subjected to the pressing force, the limiting slide plate 4 will be limited and unable to slide, thereby improving the stability of this tooling during use. It is understood that the pressing part of the fixing knob 5 needs to be set through the hollow plate 3.

[0023] A pair of brackets 1 are fixedly connected to the top surface of each of them. A track groove is opened on the side of each pair of track plates 6 that are close to each other. A sliding plate 7 is slidably connected inside the track groove. A retractable first receiving plate 10 is provided above the sliding plate 7. A plurality of first receiving grooves 11 are opened on the surface of the first receiving plate 10. During operation, the drive unit of the AGV needs to be replaced. Manual replacement requires disassembling the old drive unit and installing the new one, a process that requires manual handling of both the removed and new units. This is inconvenient as it involves a single person. Using this tooling, the disassembly process involves first pushing the sliding plate 7 to slide the track plate 6 internally. The movement of the sliding plate 7 moves the first receiving plate 10 and the first receiving groove 11 until the first receiving plate 10 is pushed below the drive unit. It is important to ensure that the first receiving groove 11 is aligned with the drive unit. Then, by extending the first receiving plate 10, it moves upwards, causing the first receiving groove 11 to contact the drive unit, thus locking the drive unit in place. Next, the drive unit will be supported, and the employee only needs to perform the disassembly operation without supporting the drive unit. After disassembly, the first receiving plate 10 is shortened, thereby separating the drive unit from the AGV. Then, the employee can pull out the sliding plate 7. During the pulling process, the first receiving plate 10 will move simultaneously, thereby pulling out the disassembled drive unit. The employee can then take away the disassembled drive unit, replace it with a new drive unit, and repeat the above steps. The new drive unit can be installed without support, improving the efficiency of installation and disassembly. Furthermore, the new drive unit can also be placed on the first receiving slot 11. During the disassembly operation, the employee can adjust the new drive unit without affecting the disassembly, and during the installation operation, the employee can adjust the old drive unit without affecting the installation.

[0024] The top surface of the sliding plate 7 is rotatably connected to a rotating sleeve 9, and an adjusting column 8 is threadedly connected inside the rotating sleeve 9. The top surface of the adjusting column 8 is fixedly connected to the bottom surface of the first receiving plate 10. When the height of the first receiving plate 10 needs to be adjusted during operation, the rotating sleeve 9 can be rotated. When the rotating sleeve 9 rotates, it will drive the adjusting column 8 to rise and fall through the thread. The rising and falling of the adjusting column 8 will drive the first receiving plate 10 to rise and fall. It can be understood that the connection between the rotating sleeve 9 and the sliding plate 7 can be achieved through bearings.

[0025] A limiting block 17 is fixedly connected to one side of each of the two sliding plates 7 that are close to each other. The limiting block 17 has a sliding hole inside, and a limiting slide rod 18 is slidably connected inside the sliding hole. The top surface of the limiting slide rod 18 is fixedly connected to the bottom surface of the first receiving plate 10. During operation, when the adjusting column 8 pushes the first receiving plate 10 to rise and fall, in order to ensure the stability of the movement, a limiting block 17 and a limiting slide rod 18 are designed. During the rising and falling of the first receiving plate 10, the limiting slide rod 18 will slide inside the sliding hole of the limiting block 17, thereby assisting the first receiving plate 10 to rise and fall and improving the stability of the tooling.

[0026] In some embodiments, a connecting rod 12 is fixedly connected to one side of each pair of limiting blocks 17 that are close to each other, and a gripping rod 13 is slidably connected to one side of each pair of connecting rods 12 that are close to each other. During operation, the sliding plate 7 can move synchronously by means of the linkage 12 and the gripping rod 13. Thus, only one sliding plate 7 needs to be pushed and the other sliding plate 7 will move accordingly, thereby eliminating the need for employees to repeat the work and improving efficiency.

[0027] The gripping rod 13 is hollow, and multiple annular grooves are formed on the surface of the gripping rod 13; During operation, since the gripping rod 13 is hollow and the connecting rod 12 is slidably connected inside the gripping rod 13, when adjusting the distance between a pair of supports 1, the connecting rod 12 can slide synchronously inside the gripping rod 13, thereby avoiding affecting the adjustment of the distance between the supports 1 and improving the stability of the equipment operation. At the same time, the groove design on the surface of the gripping rod 13 can increase the friction and prevent employees from slipping out of their hands.

[0028] In some embodiments, a plurality of balls 14 are rotatably connected to the opposite sides of a pair of sliding plates 7, and the balls 14 are in rolling connection with the track groove inside the track plate 6. During operation, multiple balls 14 are installed on the surface of the sliding plate 7, making its connection with the track plate 6 a rolling connection. Compared with the sliding connection, the friction is smaller, improving the smoothness of the equipment operation.

[0029] An auxiliary plate 15 is fixedly connected to the surface of the track plate 6. An auxiliary groove is provided inside the auxiliary plate 15. An auxiliary slide rod 16 is slidably connected inside the auxiliary groove. The top surface of the auxiliary slide rod 16 is fixedly connected to the bottom surface of the first receiving plate 10. During operation, as the first receiving plate 10 slides, it needs to support the drive unit. To improve its operational stability, an auxiliary plate 15 and an auxiliary slide rod 16 are designed. The auxiliary plate 15 and the auxiliary slide rod 16 further limit the movement of the first receiving plate 10, thereby improving the stability of the equipment operation. It should also be noted that, in the initial state, the thickness of the auxiliary groove inside the auxiliary plate 15 is greater than the distance that the first receiving plate 10 can descend, thereby preventing the auxiliary slide rod 16 from separating from the auxiliary plate 15 during the lifting and lowering process of the first receiving plate 10.

[0030] In some embodiments, a second receiving plate 19 is inserted between a pair of first receiving plates 10, and a second receiving groove 20 is provided inside the second receiving plate 19; During operation, considering that some large AGVs also have large drive units, or that only a single drive unit needs to be replaced, a second receiving plate 19 and a second receiving slot 20 were designed. When replacing the drive unit of a large AGV or when only a single drive unit needs to be replaced, the insertion direction of the bracket 1 is changed, inserting it from the side of the AGV, as shown in the attached diagram. Figure 8 As shown, the design of the second receiving plate 19 and the second receiving groove 20 enables the replacement of the drive unit or a single drive unit of the large AGV trolley, further improving the applicability of this tooling.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
