Description

Technical Field

[0001] This disclosure pertains to the field of workshop material transportation technology, specifically relating to an AGV transport frame. Background Technology

[0002] In current semiconductor testing and production processes, chip transfer is an essential task due to the switching between different stations. However, traditional transfer methods rely entirely on manual labor; both the transfer time and the chip quality during transport are entirely controlled manually. Currently, chip transfer can also utilize AGV transport vehicles with AGV transport racks, but the following problems still exist:

[0003] 1) Chips may move or slip during transportation, causing stability issues;

[0004] 2) During transportation, the chips may be damaged due to vibration or impact from the AGV transport vehicle, reducing the chip's reliability;

[0005] 3) Using a single-layer transport rack results in low transport efficiency and cannot meet the time requirements for transporting output.

[0006] 4) The AGV transport vehicle cannot accurately identify and position the AGV transport frame, which reduces the accuracy of transportation and increases the risk of production delays due to misoperation or identification errors.

[0007] To address the aforementioned issues, it is necessary to propose a reasonably designed AGV transport frame that can effectively improve these problems. Utility Model Content

[0008] The present disclosure aims to address at least one of the technical problems existing in the prior art by providing an AGV transport rack.

[0026] Figure 1 This is a schematic diagram of the structure of an AGV transport frame according to one embodiment of the present disclosure;

[0027] Figure 2 This is a schematic diagram of the structure of an AGV transport frame according to another embodiment of this disclosure. Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] like Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides an AGV transport rack 100, including a support frame 110 and at least two layers of storage baskets 120 disposed on the support frame 110.

[0030] The upper storage basket 120 is foldably connected to the lower storage basket 120, making it easier to place products to be transported into each storage basket 120. In this embodiment, the product to be transported is a chip, that is, the storage basket 120 is used to place the chip to be transported.

[0031] It should be noted that there is no specific limit to the number of storage baskets 120, and they can be selected according to actual needs. In this embodiment, a double-layer storage basket 120 is used as an example, so that chips from different batches can be placed in the upper storage basket 120 and the lower storage basket 120 respectively.

[0032] It should be further explained that, in this embodiment, the size and capacity of the storage basket 120 can be precisely calculated and optimized according to the actual output needs of the chip testing workshop to ensure that it can perfectly match the rhythm of the chip testing workshop and ensure the smooth progress of production.

[0033] In this embodiment, the AGV transport rack is equipped with at least two layers of storage baskets to realize the sequential placement of chips in different layers and batches. This not only improves the efficiency of logistics transportation, but also ensures the quality between chip batches through physical isolation. This allows chips from different batches to be stored on different layers, ensuring the independence between chip batches and thus ensuring product quality.

[0034] The inner bottom wall of the storage basket 120 is provided with multiple limiting blocks 130 at intervals, and the products to be transported are placed between two adjacent limiting blocks 130.

[0035] It should be noted that in this embodiment, multiple limiting blocks 130 are equally spaced, and the chip is positioned between two adjacent limiting blocks 130, thereby fixing the chip. The number and spacing of the limiting blocks 130 are not specifically limited and can be set according to the size of the storage basket 120 and the size of the chip.

[0036] In this embodiment, the product to be transported (chip) is placed between two adjacent limiting blocks, which can not only effectively fix the chip and prevent it from moving or slipping during transportation, but also ensure the quality stability of the chip during transportation and meet high production standards.

[0037] The AGV transport rack of this disclosure, combined with AGV transport vehicles, realizes the automation of logistics in the chip testing workshop, improves logistics efficiency, reduces labor costs, significantly enhances the overall operational effect of the workshop, and ensures the stability and safety of chips during transportation.

[0038] For example, such as Figure 2 As shown, the AGV transport rack 100 also includes an anti-slip mat 140, which is disposed on the outer bottom wall of the lowest storage basket 120.

[0039] Specifically, after placing the chips in each storage basket 120, the AGV transport vehicle moves to the AGV transport frame 100, that is, to below the bottommost storage basket 120. An anti-slip pad 140 is installed on the outer bottom wall of the bottommost storage basket 120 to increase friction between the AGV transport vehicle and the bottommost storage basket 120, reducing the risk of chip damage caused by vibration or impact from the AGV transport vehicle. This ensures the stable quality of the chips during transportation and meets high-standard production requirements.

[0040] For example, such as Figure 2 As shown, the inner bottom wall of the upper storage basket 120 has an observation window 150 at the location of the product to be transported in the corresponding lower storage basket 120.

[0041] Specifically, such as Figure 2 As shown, in this embodiment, the inner bottom wall of the upper storage basket 120 is provided with two observation windows 150. The width of the observation window 150 is less than the length of the limiting block 130. Without affecting the placement of chips in the upper storage basket 120, the placement status of chips in the lower storage basket 120 can be observed in real time through the observation window 150. This allows for timely adjustment of the chip's position if the chip in the lower storage basket 120 moves or slips, ensuring the quality stability of the chip during transportation.

[0042] For example, such as Figure 1 and Figure 2As shown, the AGV transport frame 100 also includes a first identification element 160, which is disposed on the side of the support frame 110 facing the direction of the AGV transport vehicle. The AGV transport vehicle uses the first identification element 160 to initially identify and position its corresponding AGV transport frame 100.

[0043] Preferably, in this embodiment, the first identification element 160 is a reflector. That is, the AGV transport vehicle can use the reflector to perform preliminary identification and positioning of its corresponding AGV transport frame 100.

[0044] Specifically, when an AGV transport vehicle arrives at its designated storage location, it first undergoes initial identification and positioning using a reflector on its corresponding AGV transport rack. This step ensures that the AGV transport vehicle can accurately align with the AGV transport rack, laying the foundation for subsequent operations.

[0045] In this embodiment, by setting a reflector on the side of the AGV transport frame facing the direction of the AGV transport vehicle, the visibility of the AGV transport frame can be improved in low light or nighttime environments, preventing the AGV transport vehicle from making mistakes and thus failing to find the precise position of the AGV transport frame.

[0046] For example, the AGV transport rack 100 also includes a second identification element, which is disposed in the storage basket 120; wherein, after the AGV transport vehicle performs preliminary identification and positioning of the AGV transport rack, the AGV transport vehicle performs precise identification and positioning of the corresponding AGV transport rack 100 through the second identification element.

[0047] Preferably, in this embodiment, the second identification element is a QR code. That is, after the AGV transport vehicle performs preliminary identification and positioning of the AGV transport frame using a reflector, the AGV transport frame is precisely identified and positioned by scanning the QR code on the storage basket 120.

[0048] like Figure 2 As shown, in this embodiment, there are two QR codes, and a QR code mounting plate 170 is provided on the side wall of the storage basket 120. The QR code mounting plate 170 can be mounted on the side wall of one of the storage baskets 120.

[0049] One of the QR codes is located on the QR code mounting plate 170. The operator can issue relevant instructions to the AGV transport vehicle by scanning the QR code on the side wall of the storage basket 120.

[0050] Another QR code is located on the outer bottom wall of the lowest storage basket 120 for easy scanning by the AGV transport vehicle. When the AGV transport vehicle is fully inside the transport rack, it performs a second positioning by scanning the QR code on the outer bottom wall of the lowest storage basket 120. This high-precision positioning method greatly improves the accuracy of operation.

[0051] It should be noted that during the process of the AGV transport vehicle scanning the QR code on the outer bottom wall of the lowest storage basket 120, the AGV transport vehicle's software will also use logical judgment to confirm the status of the transport rack, including confirming whether the chip exists on the transport rack and whether the transport rack is empty.

[0052] In this embodiment, the AGV transport vehicle identifies and positions its corresponding AGV transport frame using a first identification component and a second identification component, ensuring that it accurately locates the target position for each transport. This not only improves the accuracy of transport but also reduces the risk of production delays caused by misoperation or identification errors, further enhancing the identification and positioning accuracy of the transport frame.

[0053] For example, in this embodiment, the upper storage basket 120 is foldably connected to the lower storage basket 120 via a pneumatic strut; wherein, as... Figure 1 As shown, the opening angle of the upper storage basket 120 ranges from 85° to 90°. This ensures that opening the upper storage basket 120 does not affect the placement of chips in the lower storage basket 120.

[0054] For example, in this embodiment, the upper storage basket 120 is provided with a handle, which makes it easy to open and close the upper storage basket 120.

[0055] like Figure 1 and Figure 2 As shown, the working principle of the AGV transport frame 100 in this embodiment is as follows:

[0056] Controlled by AGV software, operators can easily issue transportation tasks via PAD. Once a task is issued, the AGV transport vehicle will receive the task instructions and accurately navigate to the designated storage location to execute the task.

[0057] 1) When the AGV transport vehicle arrives at the designated storage location, it first undergoes initial identification and positioning using the reflector on its corresponding transport rack. This step ensures that the AGV transport vehicle can accurately align with the transport rack, laying the foundation for subsequent operations. Subsequently, when the AGV transport vehicle is fully inside the AGV transport rack, it uses the QR code below the bottom storage basket 120 for a second positioning. This high-precision positioning method greatly improves the accuracy of the operation. During this process, the AGV software also uses logical judgments to confirm the status of the transport rack, including confirming the presence of the chip on the AGV transport rack and determining whether the AGV transport rack is empty.

[0058] 2) Place chips from different batches in upper and lower storage baskets 120 to ensure that each batch of chips maintains its original quality. After manual loading and unloading is completed, the operator will send a transportation instruction via PAD, and then the entire transportation process will officially begin.

[0059] 3) Once the AGV transport vehicle successfully delivers the chip to the designated off-line storage location, the system will issue a voice prompt, notifying the operator to retrieve the chip promptly. The operator manually transfers the chip to the test cart and then simply scans the QR codes on the storage location and the AGV transport rack to issue a retrieval command. At this point, the AGV transport rack will be marked as empty and released for future use. Simultaneously, relevant command information will be sent to the software backend to provide a basis for judging the next transport task.

[0060] The perfect integration of the AGV transport rack and AGV in this embodiment of the present disclosure realizes the automation of logistics in the chip testing workshop. This automation solution not only improves logistics efficiency but also reduces labor costs, significantly enhancing the overall operational effectiveness of the workshop.

[0061] The main processes involved in using this automated logistics system include the following aspects:

[0062] First, automated logistics transportation between chip stations has been achieved. Through the automatic navigation of AGVs and the intelligent recognition of AGV transport racks, chips can be accurately transported from one station to another without human intervention.

[0063] Secondly, the application of the double-layer storage basket design enables the AGV system to arrange chips in a hierarchical and batch-wise order, which not only improves logistics and transportation efficiency but also ensures the quality between chip batches through physical isolation. This design allows different batches of chips to be stored on different layers, guaranteeing the independence between chip batches.

[0064] Furthermore, through close integration with AGV operating software, the transport racks are brought into the realm of automation. The software control system can monitor the status and position of the transport racks in real time and automatically adjust transportation strategies according to needs, ensuring the smooth operation of the logistics process.

[0065] Meanwhile, the application of reflectors and secondary scanning positioning technology greatly improves the precise positioning of AGV transport frames. This enables AGVs to more accurately identify and position transport frames, thereby avoiding transport errors and delays caused by inaccurate positioning.

[0066] Ultimately, by automating logistics and transportation, operational efficiency was successfully improved, labor costs were reduced, and the original chip turnaround time was shortened. This not only avoided the delays and machine idleness caused by manual chip preparation, but also saved existing transport vehicle resources, increasing the space utilization rate of the chip workshop by 30%.

[0067] In conclusion, the design of the AGV transport rack and its perfect integration with AGVs have successfully automated the logistics of the chip testing workshop, providing a strong guarantee for the efficient operation of the workshop and the improvement of product quality.

[0068] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the embodiments of this disclosure, and the embodiments of this disclosure are not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the embodiments of this disclosure, and these modifications and improvements are also considered to be within the protection scope of the embodiments of this disclosure.
