Description

Technical Field

[0001] This application relates to the field of automotive parts testing technology, and in particular to a tray loading and unloading machine. Background Technology

[0002] In the field of automobile manufacturing and related component testing, with the continuous development of the automotive industry, the quality testing requirements for automotive components are becoming increasingly stringent. As a key component of the engine, the quality of the automotive piston directly affects the engine's performance and reliability. Therefore, efficient and accurate testing of automotive pistons has become particularly important. In the entire testing process, the loading and unloading of pistons is one of the key factors affecting testing efficiency and quality.

[0003] Currently, several methods are commonly used to load and unload pistons during automotive piston inspection. One common method is manual handling, where workers move trays containing multiple pistons one by one to the inspection station. After the pistons are inspected and moved to the next station, the empty trays at the inspection station are manually removed for unloading. Another method is to use a simple conveyor device, such as a belt conveyor, to transport the trays to the inspection station.

[0004] However, manual handling is inefficient and cannot meet the needs of large-scale production. Furthermore, it is prone to human error, affecting the accuracy of test results. While simple conveying devices improve efficiency to some extent, they are limited in function and lack effective handling for transferring trays between different workstations. The movement of the tray from the testing station to the unloading station often requires additional manual assistance, increasing labor costs and operational complexity. This prevents automated loading and unloading processes, resulting in a low degree of automation in the entire testing process and increased production and time costs. Utility Model Content

[0005] To improve the efficiency and automation of the piston loading and unloading process, this application provides a tray loading and unloading machine.

[0006] The tray loading and unloading machine provided in this application adopts the following technical solution: A tray loading and unloading machine includes: a frame; a loading mechanism mounted on the frame, the loading mechanism being used to transport trays, moving the trays from a loading station to an inspection station; a conversion mechanism mounted on the frame, the conversion mechanism being used to transport the trays, moving the trays from the inspection station to the conversion station, the conversion station being located below the inspection station; and an unloading mechanism mounted on the frame, the unloading mechanism being located below the loading mechanism, the unloading mechanism being used to transport the trays, moving the trays from the conversion station to the unloading station.

[0007] By adopting the above technical solution, the frame provides the installation foundation for the loading mechanism, conversion mechanism, and unloading mechanism, ensuring the stable operation of each mechanism. The loading mechanism transports the tray from the initial loading station to the inspection station, facilitating the inspection of the items carried on the tray. The conversion mechanism transports the inspected tray from the inspection station to the conversion station located below the inspection station, realizing the conversion of the tray between stations at different heights. The unloading mechanism transports the tray from the conversion station to the unloading station, completing the unloading operation. The entire loading and unloading machine realizes an automated conveying process for the tray from feeding to inspection to unloading, reducing manual intervention, lowering labor intensity, and improving efficiency.

[0008] Optionally, both the feeding mechanism and the unloading mechanism are conveyors, and the feeding directions of the feeding mechanism and the unloading mechanism are parallel and opposite.

[0009] By adopting the above technical solution, both the loading and unloading mechanisms are conveyors, capable of automatically transporting trays. The loading mechanism transports the trays from the loading station to the inspection station, realizing the tray loading operation; the unloading mechanism transports the trays from the transfer station to the unloading station, completing the tray unloading operation. Furthermore, the loading and unloading mechanisms are parallel and opposite in their conveying directions, allowing for a rational layout within a limited space, efficiently completing the tray loading and unloading process, avoiding mutual interference during transport, and improving the overall operating efficiency of the tray loading and unloading machine.

[0010] Optionally, the conversion mechanism includes a vertical drive and a conversion table. The fixed end of the vertical drive is connected to the frame, and the conversion table is used to carry the tray. The conversion table is located at the moving end of the vertical drive, and the vertical drive drives the conversion table to move vertically, so that the conversion table can cooperate with the loading mechanism and the unloading mechanism respectively to realize the conveying of the tray.

[0011] By adopting the above technical solution, the fixed end of the vertical drive component of the conversion mechanism is connected to the frame, providing stable support for the movement of the conversion table. The conversion table is used to carry the tray and is located at the moving end of the vertical drive component. It can move vertically under the drive of the vertical drive component. When it moves to the position that cooperates with the feeding mechanism, it can receive the tray conveyed by the feeding mechanism and move it from the inspection station to the conversion station. When it moves to the position that cooperates with the unloading mechanism, it can convey the tray to the unloading mechanism, and then move the tray from the conversion station to the unloading station, realizing the unloading and loading of the tray between different height stations.

[0012] Optionally, the system also includes a feeding mechanism, which is movably disposed on one side of the frame. The feeding mechanism is used to transport the tray and move the tray from the storage station to the loading station.

[0013] By adopting the above technical solution, the feeding mechanism is movably located on one side of the frame, and can move flexibly between the storage station and the loading station to transport the tray from the storage station to the loading station, realizing the initial position transfer of the tray. This prepares the tray for further transport to the inspection station by the loading mechanism, making the entire tray loading and unloading process more seamless and efficient, and reducing the need for manual handling of the tray.

[0014] Optionally, the feeding mechanism includes a support frame, a support platform, and a roller assembly. The support platform is used to support the tray and is mounted on the support frame. The roller assembly is located at the bottom end of the support frame.

[0015] By adopting the above technical solution, the support frame is used to support the carrier platform, which can support the tray. The roller assembly is located at the bottom of the support frame, which facilitates the overall movement of the feeding mechanism, thereby moving the tray from the storage station to the loading station.

[0016] Optionally, the feeding mechanism includes two sets of driving components, which are respectively disposed on both sides of the upper end of the support platform. Each driving component includes a driving element, a transmission element, and a driving conveyor belt. The driving element is disposed on the lower side of the support platform, and the transmission element is disposed on the support platform. The output end of the driving element is connected to the transmission element. The driving conveyor belt is mounted on the transmission element. The working surfaces of the driving conveyor belts of the two sets of driving components are arranged opposite to each other. The two sets of driving conveyor belts are respectively used to abut against both sides of the tray to drive the tray to move to the loading station.

[0017] By adopting the above technical solution, the two sets of drive components of the feeding mechanism are respectively set on the upper sides of the support platform. The drive component in the drive component is set on the lower side of the support platform to provide power for transmission. The transmission component is set on the support platform. The output end of the drive component is connected to the transmission component to transmit the power of the drive component to the transmission component. The drive conveyor belt is mounted on the transmission component and can move under the drive of the transmission component. The action surfaces of the drive conveyor belts of the two sets of drive components are set opposite to each other and can respectively abut against the two sides of the tray. The friction between the drive conveyor belt and the tray is used to drive the tray to move to the loading station, realizing the conveying of the tray from the storage station to the loading station.

[0018] Optionally, the feeding mechanism includes two guide members, which are respectively disposed on both sides of the upper end of the support platform. The two guide members are arranged in a trumpet shape, such that the horizontal distance between the first ends of the two guide members away from the loading station is greater than the horizontal distance between the second ends of the two guide members close to the loading station. The second end of the guide member is disposed on the side of the drive assembly away from the loading station.

[0019] By adopting the above technical solution, the two guides of the feeding mechanism are respectively set on both sides of the upper part of the support platform and distributed in a trumpet shape, so that the horizontal distance of the first end away from the loading station is greater than the horizontal distance of the second end closer to the loading station. The second end of the guide is located on the side of the drive assembly away from the loading station. In this way, when the tray is placed on the support platform, the trumpet-shaped guide guides the tray, allowing it to smoothly enter between the drive conveyor belts of the two drive assemblies. This facilitates the subsequent drive conveyor belt to move the tray to the loading station, improving the accuracy and efficiency of feeding. At the same time, it can keep the tray away from the drive assembly when placing it, improving operational safety.

[0020] Optionally, the feeding mechanism is provided with an extension plate, and the end of the support platform facing the feeding mechanism is provided with a slot. When the feeding mechanism cooperates with the feeding mechanism, the extension plate extends into the slot.

[0021] By adopting the above technical solution, the extension plate of the feeding mechanism cooperates with the slot of the feeding mechanism's carrier platform. When the feeding mechanism and the feeding mechanism cooperate, the extension plate extends into the slot, making the connection between the feeding mechanism and the feeding mechanism more stable, improving the positioning accuracy, and providing a stable transition structure for the Tray to move smoothly from the feeding mechanism to the feeding mechanism, ensuring that the Tray can move smoothly from the storage station to the feeding station and then to the inspection station.

[0022] Optionally, the feeding mechanism is provided with a limiting component, which includes a wedge block, a sliding member, and an elastic member. The support platform is provided with a mounting groove and a mounting part. The mounting groove is opened in the support platform, and the mounting part is located below the support platform. The wedge block is located in the mounting groove. The upper end of the elastic member is connected to the wedge block, and the lower end of the elastic member is connected to the mounting groove. The upper end of the sliding member is connected to the wedge block, and the lower end of the sliding member is slidably connected to the mounting part. The inclined surface of the wedge block is used to cooperate with the extension plate, so that when the extension plate is inserted into the slot, the extension plate abuts against the inclined surface and drives the wedge block to move down, thereby releasing the limitation on the tray on the support platform.

[0023] By adopting the above technical solution, in the limiting component of the feeding mechanism, the wedge block is installed in the mounting groove of the support platform. The upper end of the elastic element is connected to the wedge block, and the lower end is connected to the mounting groove of the support platform. The upper end of the sliding element is connected to the wedge block, and the lower end is slidably connected to the mounting part below the support platform. In the initial state, the wedge block can limit the tray on the support platform to prevent it from moving arbitrarily. When the feeding mechanism cooperates with the loading mechanism, when the extension plate of the loading mechanism extends into the slot of the support platform, the extension plate will abut against the inclined surface of the wedge block. When the extension plate pushes the wedge block, the inclined surface can convert the horizontal movement of the extension plate into the vertical movement of the wedge block. Due to the sliding action of the sliding element, the extension plate will drive the wedge block to move downward, and at the same time the elastic element is compressed, thereby releasing the limitation on the tray on the support platform, so that the tray can smoothly enter the subsequent conveying process from the loading station.

[0024] Optionally, the feeding mechanism includes a tilting table, the first end of which is rotatably connected to the end of the support platform away from the feeding mechanism. A support structure is provided below the support platform, one end of which is connected to the support platform, and the other end of which is used to support the tilting table to limit the minimum height of the second end of the tilting table.

[0025] By adopting the above technical solution, the first end of the tilting table of the feeding mechanism is rotatably connected to the end of the support platform away from the feeding mechanism, allowing the tilting table to rotate relative to the support platform. This facilitates adjustment of its position or angle as needed, enabling the tray to be supported and transported when the tilting table is horizontal. When the tray needs to be pushed, the tilting table can be tilted to move the tray closer to the drive component, keeping the operator away from the drive component and improving operational safety. The support structure located below the support platform, with one end connected to the support platform and the other end supporting the tilting table, provides support for the tilting table, limits the minimum height of the second end of the tilting table, and ensures that the tilting table is in a suitable position and angle, thereby stably assisting the feeding mechanism in transporting the tray.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. It realizes the automated conveying of the tray from the storage station to the loading station, inspection station, transfer station and then to the unloading station, which improves the automation level of automotive piston inspection and reduces manual intervention; 2. It avoids the inefficiency and human error of manual handling, meets the needs of large-scale production, and improves the accuracy of test results; 3. It solves the problem of insufficient pallet handling capacity of simple conveying devices when transferring pallets between different workstations, thus reducing production and time costs.

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0034] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0035] like Figure 1 and Figure 2 As shown in the figure, this application discloses a tray loading and unloading machine (hereinafter referred to as "loading and unloading machine"), which includes a frame 1, a loading mechanism 2, a conversion mechanism 3, an unloading mechanism 4 and a feeding mechanism 5.

[0036] like Figure 1 and Figure 2 As shown, the loading mechanism 2, the conversion mechanism 3, and the unloading mechanism 4 are all mounted on the frame 1, and the feeding mechanism 5 is movably mounted on one side of the frame 1. The loading mechanism 2 is used to transport the tray 100, moving the tray 100 from the loading station to the inspection station; the conversion mechanism 3 is used to transport the tray 100, moving the tray 100 from the inspection station to the conversion station located below the inspection station; the unloading station is located below the loading station, and the unloading mechanism 4 is located below the loading mechanism 2, used to transport the tray 100, moving the tray 100 from the conversion station to the unloading station; the feeding mechanism 5 is used to transport the tray 100, moving the tray 100 from the storage station to the loading station, thus achieving automated conversion of the tray 100 between different stations, improving the efficiency and accuracy of loading and unloading for automotive piston inspection, and reducing manual intervention and errors.

[0037] like Figure 1As shown, both the feeding mechanism 2 and the unloading mechanism 4 are conveyors. They can adopt the same structure, and their conveying directions are parallel and opposite. Specifically, the feeding mechanism 2 includes a motor and a conveyor belt. The motor is an AC motor, characterized by strong power and good stability. The motor is fixed to the frame 1 by bolts or other means. The conveyor belt is made of rubber, possessing a certain degree of flexibility and wear resistance. The conveyor belt is fitted onto a drive roller, which is connected to the output shaft of the motor. When the motor starts, it drives the drive roller to rotate, thereby driving the conveyor belt to rotate cyclically, realizing the conveying of the tray 100. The conveyor belt can also be a chain conveyor belt, which has a stronger load-bearing capacity and is suitable for conveying heavier trays 100. The motor drives the conveyor belt to rotate, conveying from one end to the other along the conveying direction, realizing the transfer of the tray 100 from one position to another. It is understood that the conveyor can be an existing belt conveyor, or other types of conveyors can be selected as needed, as long as they meet the usage requirements.

[0038] Specifically, the unloading mechanism 4 also includes a motor and a conveyor belt. Its structure and working principle are similar to the loading mechanism 2. The motor is fixedly mounted on the frame 1, and the conveyor belt is fitted onto the drive roller, which is connected to the output shaft of the motor. The motor starts, driving the conveyor belt to rotate, thus conveying the tray 100. The difference is that the conveying direction of the unloading mechanism 4 is parallel and opposite to that of the loading mechanism 2. This arrangement makes the entire loading and unloading process more compact and efficient. Similarly, the motor of the unloading mechanism 4 can be replaced with a servo motor, and the conveyor belt can also be a chain conveyor belt. The conveyor belt of the unloading mechanism 4 rotates in the opposite direction to that of the loading mechanism 2, conveying the tray 100 from the transfer station to the unloading station to complete the unloading operation.

[0039] like Figure 1 As shown, specifically, the conversion mechanism 3 includes a vertical drive component 31 and a conversion table 32. The vertical drive component 31 can be a cylinder, which is fixedly mounted on the frame 1 by bolts. The piston rod of the cylinder serves as the moving end, and the conversion table 32 is fixedly mounted on the end of the piston rod. The conversion table 32 includes a table body and a conveying structure. The table body is usually welded from metal plates, possessing a certain strength and stability, and is used to support the tray 100. The table body can be slidably connected to the frame 1 to improve movement stability. The conveying structure is located on the table body and can be an independently installed belt conveyor. When the piston rod of the cylinder extends or retracts, it drives the conversion table 32 to move vertically. The vertical drive component 31 can also be replaced by an electric push rod, which can more precisely control the moving distance and speed of the conversion table 32. The extension and retraction of the vertical drive component 31 allows the conversion table 32 to move between workstations at different heights, thereby realizing the conversion of the tray 100 between the inspection workstation and the conversion workstation.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the unloading station protrudes from the loading station, which increases the difficulty of loading. By setting up the feeding mechanism 5, it is easier to place the Tray 100 on the loading station.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, specifically, the feeding mechanism 5 includes a support frame 51, a support platform 52, a roller assembly 53, two sets of drive components 54, two guide members 55, a limiting component 56, and a tilting table 57. The support frame 51 is welded from metal tubing, possessing a certain strength and stability, and is used to support the support platform 52. When the support frame 51 cooperates with the loading mechanism 2, it is erected above the unloading station to reduce the risk of interference. The support platform 52 is typically made of sheet metal and is used to support the tray 100. The roller assembly 53 is installed at the bottom of the support frame 51, and the rollers can be casters to facilitate the movement of the feeding mechanism 5.

[0042] like Figure 1 , Figure 2 and Figure 5 As shown, the drive assembly 54 includes a drive component 541, a transmission component 542, and a drive conveyor belt 543. The drive component 541 can be a small motor, which is fixedly mounted on the underside of the support platform 52 by bolts. The transmission component 542 can be a pulley, which is connected to the output shaft of the drive component 541, and the drive conveyor belt 543 is mounted on the pulley. The working surfaces of the drive conveyor belts 543 of the two sets of drive assemblies 54 are arranged opposite each other, respectively for abutting against both sides of the tray 100. When the drive component 541 is started, it drives the drive conveyor belt 543 to rotate, thereby moving the tray 100 to the loading station.

[0043] The two guide members 55 are typically made of sheet metal and are arranged in a trumpet shape. The horizontal distance between the first ends of the two guide members 55 away from the loading station is greater than the horizontal distance between the second ends of the two guide members 55 near the loading station. The second end of the guide member 55 is located on the side of the drive assembly 54 away from the loading station, and along the conveying direction, the second end of the guide member 55 is flush with the working surface of the drive conveyor belt 543. This arrangement can guide the tray 100 to accurately enter the conveying range of the drive assembly 54.

[0044] like Figure 1 , Figure 2 and Figure 5 As shown, the feeding mechanism 2 is provided with an extension plate 21, and the bearing platform 52 is provided with a slot 521 at one end facing the feeding mechanism 2. When the feeding mechanism 5 cooperates with the feeding mechanism 2, the extension plate 21 extends into the slot 521 to achieve positioning.

[0045] The limiting component 56 is used to selectively limit the tray 100 on the support platform 52. The limiting component 56 includes a wedge block 561, a sliding member 562, and an elastic member 563. The support platform 52 has a mounting groove 522 and a mounting portion 523. The mounting groove 522 is formed in the support platform 52, and the mounting portion 523 is located below the support platform 52. The wedge block 561 is located in the mounting groove 522. The upper end of the elastic member 563 is connected to the wedge block 561, and the lower end of the elastic member 563 is connected to the mounting groove 522. The upper end of the sliding member 562 is connected to the wedge block 561, and the lower end of the sliding member 562 is slidably connected to the mounting portion 523. The inclined surface of the wedge block 561 is used to cooperate with the extension plate 21. The initial state of the wedge block 561 is protruding from the upper end of the support platform 52, used to limit the tray 100. When the extension plate 21 is inserted into the slot 521, it abuts against the inclined surface and drives the wedge block 561 to move downward, releasing the restriction on the tray 100 on the support platform 52. Preferably, the elastic element 563 is a spring. The mounting part 523 is provided with a sliding hole, and the sliding element 562 is slidably connected to the sliding hole. A limiting block can be provided at the lower end of the sliding element 562. The cross-sectional area of ​​the limiting block is larger than the cross-sectional area of ​​the sliding hole to limit the maximum upward movement distance of the sliding element 562 and improve reliability. The support platform 52 is provided with necessary clearance grooves to allow the extension plate 21 to be smoothly inserted into the slot 521.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, the first end of the tilting table 57 is rotatably connected to the end of the support table 52 away from the feeding mechanism 2. A support structure 58 is provided below the support table 52. One end of the support structure 58 is connected to the support table 52, and the other end of the support structure 58 is used to support the tilting table 57 to limit the minimum height of the second end of the tilting table 57.

[0047] It is understandable that the loading and unloading machine also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the loading and unloading machine can operate normally; the shape, size, material and quantity of each part of the loading and unloading machine can be determined as needed, as long as it can achieve the corresponding functions.

[0048] The implementation principle of this embodiment is as follows: through the coordinated work of the loading mechanism 2, the conversion mechanism 3, the unloading mechanism 4, and the feeding mechanism 5, the automated conveying of the tray 100 between different workstations is realized. The feeding mechanism 5 can pre-place multiple trays 100 on the support platform 52. Its movable design facilitates the transport of the trays 100 to the vicinity of the loading station. The drive component 54 and the guide component 55 work together to accurately convey the trays 100 onto the loading mechanism 2. The loading mechanism 2 conveys the trays 100 from the storage station to the inspection station. The conversion mechanism 3 transfers the inspected trays 100 from the inspection station to the conversion station. The unloading mechanism 4 conveys the trays 100 from the conversion station to the unloading station. Compared to traditional manual handling and simple conveying devices, this loading and unloading machine improves the efficiency and accuracy of loading and unloading, reduces manual intervention and human error, lowers production costs and time costs, and better meets the needs of large-scale production. Meanwhile, the cooperation between the extension plate 21 of the feeding mechanism 5 and the slot 521 of the bearing table 52, the setting of the limiting component 56, and the flip-table design of the flip table 57 further improve the entire loading and unloading system, increasing its flexibility and practicality.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
