Description

Technical Field

[0001] This utility model relates to the field of chip testing technology, specifically to a material flow system for a fully automatic three-temperature testing machine. Background Technology

[0002] With the development of electronic technology, chips are becoming increasingly integrated, with increasingly finer structures, more and more processes, and increasingly complex manufacturing processes. Inevitably, some latent defects will be generated in the chips during the manufacturing process, and these defects usually need to be operated for about a thousand hours before they are fully exposed.

[0003] Therefore, the current main method to accelerate defect exposure is to conduct chip environmental adaptability testing. Environmental adaptability testing usually adopts three-temperature testing, which involves testing at three temperatures: low temperature, room temperature, and high temperature. These are generally defined as low temperature -55°C, room temperature 25°C, and high temperature 125°C.

[0004] The material handling system is an essential component of the three-temperature testing equipment. It is used to transfer materials from the loading area to the testing module, and then transfer the tested materials to the unloading area. In order to better transfer and position the material trays, the material trays in the loading area are placed on the positioning carriers on the handling system. The material trays and positioning carriers are then sent into the testing module together. After the test is completed, the material trays are separated from the positioning carriers. Therefore, the positioning carriers need to be recycled. The material handling systems in the current technology require a robotic arm to move the positioning carriers between the loading and unloading conveyor tracks. The robotic arm requires a large amount of space for movement and is also costly.

[0005] In view of this, there is an urgent need for a fully automatic material flow system for a three-temperature testing machine to solve the above problems. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A fully automatic three-temperature testing machine material flow system includes: a feeding track, a first transfer track, a discharging track, a second transfer track, a first turning track, a second turning track, a third turning track, and a fourth turning track; The loading track and the unloading track are arranged side by side. The loading track includes two first conveyor belts arranged in parallel in the horizontal direction, and the unloading track includes two second conveyor belts arranged in parallel in the horizontal direction. The first transfer track and the second transfer track are arranged side by side, and the first transfer track and the second transfer track are respectively located at the two ends between the loading track and the unloading track. The conveying direction of the first transfer track and the second transfer track is perpendicular to the conveying direction of the first transfer track. The first turning track and the second turning track are respectively located at both ends between the two first conveyor belts, and the conveying direction of the first turning track and the second turning track is perpendicular to the conveying direction of the loading track. The third and fourth turning tracks are respectively located at both ends between the two second conveyor belts, and the conveying direction of the third and fourth turning tracks is perpendicular to the conveying direction of the unloading track.

[0008] A first drive assembly is provided at the bottom of the first turning track, which is used to drive the first turning track to perform lifting and lowering movements.

[0009] A second drive assembly is provided at the bottom of the second turning track, which is used to drive the second turning track to perform lifting and lowering movements.

[0010] The bottom of the third turning track is provided with a third drive component, and the second drive component is used to drive the third turning track to perform lifting and lowering movements.

[0011] The bottom of the fourth turning track is provided with a fourth drive assembly, which is used to drive the fourth turning track to perform lifting and lowering movements.

[0012] The height of the conveying surface at the top of the first transfer runway is higher than the height of the conveying surfaces at the top of the loading and unloading runways.

[0013] The height of the conveying surface at the top of the second transfer track is higher than the height of the conveying surfaces at the top of the loading track and the unloading track.

[0014] The conveying surfaces of the loading and unloading tracks are at the same height.

[0015] The transport surfaces of the first and second transfer runways are at the same height.

[0016] The first drive assembly includes a base and a lifting cylinder. The first steering track is disposed on the base, and the lifting cylinder is disposed on the base. The conveying end of the lifting cylinder is connected to the first steering track.

[0017] The above-described structure of this utility model can achieve the following beneficial effects: The system uses a U-shaped circular conveyor system consisting of a loading track, a first transfer track, an unloading track, and a second transfer track. The positioning carrier is then transferred via a first turning track, a second turning track, a third turning track, and a fourth turning track, thus completing the circular transport of the positioning carrier.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0022] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0023] like Figure 1As shown, a fully automatic three-temperature testing machine material flow system includes: a feeding track 1, a first transfer track 2, a discharging track 3, a second transfer track 4, a first turning track 5, a second turning track 6, a third turning track 7, and a fourth turning track 8 (the feeding track 1, the first transfer track 2, the discharging track 3, the second transfer track 4, the first turning track 5, the second turning track 6, the third turning track 7, and the fourth turning track 8 are all composed of two parallel synchronously moving conveyor belts). The loading track 1 and the unloading track 3 are arranged side by side, and the conveying direction of the loading track 1 is opposite to that of the unloading track. The loading track 1 includes two first conveyor belts 11 arranged in parallel in the horizontal direction, and the unloading track 3 includes two second conveyor belts 31 arranged in parallel in the horizontal direction. The first transfer track 2 and the second transfer track 4 are arranged side by side, and the conveying direction of the first transfer track 2 is opposite to that of the second transfer track 4. The first transfer track 2 and the second transfer track 4 are respectively located at the two ends between the loading track 1 and the unloading track 3. The conveying direction of the first transfer track 2 and the second transfer track 4 is perpendicular to the conveying direction of the first transfer track 2. The first turning track 5 and the second turning track 6 are respectively located at both ends between the two first conveyor belts 11, and the conveying direction of the first turning track 5 and the second turning track 6 is perpendicular to the conveying direction of the feeding track 1. The third turning track 7 and the fourth turning track 8 are respectively located at both ends between the two second conveyor belts 31, and the conveying direction of the third turning track 7 and the fourth turning track 8 is perpendicular to the conveying direction of the unloading track 3.

[0024] Based on the above structure, the loading track 1, the first transfer track 2, the unloading track 3, and the second transfer track 4 form a U-shaped circulating conveyor track. In use, the positioning carrier is placed on the circulating conveyor track. When the positioning carrier moves to the loading area, the material tray is placed on the positioning carrier and then conveyed to the testing module. The tested material tray and the positioning carrier carrying it are then conveyed via the second transfer track 4 to the unloading track 3, and then to the unloading area. The material tray is removed from the positioning carrier and then conveyed via the first transfer track 2 to the unloading area. On the loading track 1, the positioning carrier is transported in a cyclical manner. Turning tracks (first turning track 5, second turning track 6, third turning track 7, and fourth turning track 8) are set at both ends of the loading track 1 and the unloading track 3. When the positioning carrier moves to the end of the loading track 1 or the end of the unloading track 3, the corresponding turning track performs work to transfer the positioning carrier to the first transfer track 2 or the second transfer track 4, and then transports it to the loading track 1 or the unloading track 3 via the first transfer track 2 or the second transfer track 4.

[0025] like Figure 2As shown, a first drive assembly is provided at the bottom of the first turning track 5. The first drive assembly is used to drive the first turning track 5 to move up and down. Thus, when the positioning carrier is transferred from the loading track 1 to the second transfer track 4, the first drive assembly drives the first turning track 5 to rise, so that the positioning carrier is separated from the loading track 1, thereby avoiding the first conveyor belt 11 from interfering with the transfer of the positioning carrier.

[0026] Further optimization involves a second drive assembly at the bottom of the second turning track 6, which drives the second turning track 6 to move up and down; a third drive assembly at the bottom of the third turning track 7, which drives the third turning track 7 to move up and down; and a fourth drive assembly at the bottom of the fourth turning track 8, which drives the fourth turning track 8 to move up and down. The conveying surface height at the top of the first transfer track 2 is higher than the conveying surface height at the top of the loading track 1 and the unloading track 3. The functions of the second drive assembly, the third drive assembly, and the third drive assembly are the same as those of the first drive assembly, all aimed at preventing the first conveyor belt 11 or the second conveyor belt 31 from interfering with the movement of the positioning carrier, which will not be described in detail here.

[0027] Further optimization involves arranging the top of the second transfer track 4 at a higher conveying surface height than the top of the loading track 1 and the unloading track 3 to facilitate the movement of the positioning carrier. This, combined with the lifting and lowering first turning track 5, second turning track 6, third turning track 7, and fourth turning track 8, allows the positioning carrier to be received or transported at a higher height, further avoiding interference with the first conveyor belt 11 or the second conveyor belt 31.

[0028] Further optimization involves ensuring that the conveying surfaces of the loading track 1 and the unloading track 3 are at the same height for easier drive control; and that the conveying surfaces of the first transfer track 2 and the second transfer track 4 are at the same height.

[0029] like Figure 2 As shown, in order to adjust the height of the first turning track 5, the first drive assembly includes a base 9 and a lifting cylinder. The first turning track 5 is mounted on the base 9, and the lifting cylinder is mounted on the base 9. The conveying end of the lifting cylinder is connected to the first turning track 5. The lifting cylinder performs work to change the height of the first special track 5. The structures of the second drive assembly, the third drive assembly, and the third drive assembly are the same as those of the first drive assembly, and will not be described in detail here.

[0030] Further optimization involves setting up sensors or limiting structures at multiple locations to ensure accurate transfer of the positioning vehicle, thereby preventing excessive movement of the positioning vehicle and affecting the transport process.

[0031] In summary, the loading track 1, the first transfer track 2, the unloading track 3, and the second transfer track 4 form a U-shaped circular conveyor track. In use, the positioning carrier is placed on the circular conveyor track. When the positioning carrier moves to the loading area, the material tray is placed on the positioning carrier and then conveyed to the testing module. The tested material tray and the positioning carrier carrying it are then conveyed via the second transfer track 4 to the unloading track 3, and then to the unloading area. The material tray is removed from the positioning carrier and then conveyed via the first transfer track 2 to the loading area. On the material feeding track 1, the positioning carrier is cyclically transported; and at both ends of the feeding track 1 and the unloading track 3, there are turning tracks (first turning track 5, second turning track 6, third turning track 7 and fourth turning track 8 respectively). When the positioning carrier moves to the end of the feeding track 1 or the end of the unloading track 3, the corresponding turning track performs work to transfer the positioning carrier to the first transfer track 2 or the second transfer track 4, and then transports it to the feeding track 1 or the unloading track 3 via the first transfer track 2 or the second transfer track 4. This application uses a U-shaped circular conveying track composed of a loading track 1, a first transfer track 2, a unloading track 3, and a second transfer track 4. The positioning carrier is transferred through a first turning track 5, a second turning track 6, a third turning track 7, and a fourth turning track 8 to complete the circular conveying of the positioning carrier. It occupies less space in terms of equipment height and has a lower cost compared to a robotic arm.

[0032] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
