Description

Technical Field

[0001] This invention relates to the field of template replacement technology, and in particular to a template replacement mechanism for a transport vehicle. Background Technology

[0002] The current template machine production relies on manual handling of templates, which is very cumbersome. A template changing mechanism needs to be designed to send the template to be processed into the changing mechanism of the transport vehicle, transport it to the processing point, and then return to load the next template to be processed. Therefore, it is very important to design a template changing mechanism with a stable structure to solve the problem of low efficiency in the current mode.

[0003] In the prior art, a template pull-out mechanism disclosed in patent publication number CN221834589U includes an inner template one and an inner template two arranged symmetrically. The inner template one has insert rods on both sides, and the insert rods are connected to the inner template one by bolt one. The inner template two has sleeve rods on both sides, and the sleeve rods are connected to the inner template two by bolt two. One side of the insert rod extends into the sleeve rod, and one side of the sleeve rod has a fastening bolt that extends into the inside and is threadedly connected to the insert rod. This prior art document still relies on the traditional template replacement method, which is completely manual and has very low efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing template replacement relies on manual labor, which is very inefficient. The template of this invention can be automatically replaced by a fully automatic gripper assembly. The template is placed into the first template placement part and the second template placement part, and the processed template and the template to be processed can be placed in at the same time, making the replacement more convenient.

[0005] Another objective of this invention is to address the problem that existing gripper assembly structures are not stable enough and cannot achieve high-precision control. The gripper assembly of this invention includes an upper moving rail and a lower moving rail, which are driven by a tire assembly. One end of both the upper and lower moving rails is convex and embedded in the connecting piece, resulting in more stable stroke and higher precision.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a transport vehicle template changing mechanism, comprising a housing, a gripper assembly at the bottom of the housing, a first template placement part and a second template placement part distributed downwards from the assembly, a tire assembly on one side of the gripper assembly, and side plates on both sides of the first template placement part and the second template placement part.

[0007] Preferably, the tire assembly includes a drive belt and a positioning element. The drive belt passes through the positioning element. Above the tire assembly is a tire drive motor. When the tire assembly moves, it drives the drive belt to move, which in turn drives the positioning element and its fixed gripper assembly to move. The gripper assembly extends forward, and the gripper on the gripper assembly grabs the corresponding hole on the template and then pulls it back inward, placing the grabbed template on the first template placement part or the second template placement part.

[0008] Preferably, the gripper assembly includes an upper moving rail and a lower moving rail, both ends of which are convex, and the lower moving rail has holes on both sides of its cross-section. The upper and lower moving rails are fixed together by several connecting parts.

[0009] Preferably, the connector has a concave structure, with the convex portions at both ends of the upper and lower moving rails embedded inside the connector.

[0010] Preferably, a support arm is fixed at the lower end of the lower moving rail. The main body of the support arm is a trapezoidal structure. A gripper driver is fixed at both ends of the support arm, and a gripper is connected below the gripper driver.

[0011] Preferably, one side of the lower moving rail is connected to a positioning element on the tire assembly.

[0012] Preferably, the cross-sections of the first template placement part and the second template placement part are both continuous trapezoidal cross-sections.

[0013] Preferably, a plurality of side plate drive motors are provided on one side of the housing, and a connecting rod is provided below the side plate. The side plate drive motors drive the connecting rod below the side plate to realize the retraction of the side plate, and the side plate can retract back to between the first template placement part and the second template placement part.

[0014] Preferably, one side of the transport vehicle is an operating platform, on which a template fixing component is installed. The upper part of the housing is provided with a telescopic part and a movable part. Above the movable part is a top track. The telescopic part controls the telescopic extension and retraction of the entire transport vehicle, and the movable part drives the movement of the entire transport vehicle.

[0015] Preferably, the shell is provided with several shell reinforcing ribs.

[0016] Compared with existing technologies, the beneficial effects of this invention are: This invention eliminates the tedious steps and time consumption of manual operation through a fully automated template changing mechanism. For example, in the traditional template changing process, manual operation may take a lot of time to change the template, while this invention can complete the process in minutes, greatly improving production efficiency. Manual template changing is prone to errors; this invention ensures the accuracy of template changing and reduces production interruptions caused by human error.

[0017] The automated template replacement of this invention reduces the physical exertion of workers in repetitive labor, improves the working environment, and also reduces the risk of occupational diseases caused by prolonged repetitive labor.

[0018] This invention enables automated template replacement, which can be completed quickly during production without prolonged downtime. This allows the production line to operate more continuously, reducing production interruptions caused by template replacement and thus improving overall production efficiency.

[0019] The gripper assembly of this invention ensures stability during movement by embedding the convex structure of the upper and lower moving rails into the connecting member. This design enables the gripper to operate with higher precision, such as in high-precision assembly or the gripping of tiny parts, achieving millimeter-level or even higher precision control.

[0020] The convex structure of the upper and lower moving rails and the embedded design of the connecting parts in this invention enhance the overall structural stability of the gripper assembly. Under high load or high frequency operation, this structure effectively reduces vibration and sway, ensuring stable operation of the gripper. Attached Figure Description

[0029] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1: Refer to Figures 1 to 7 A template changing mechanism for a transport vehicle includes a housing 4. The housing 4 plays a crucial role in supporting and protecting the entire mechanism, providing a stable installation space for the internal components and resisting external interference and impacts to ensure the normal operation of the entire mechanism. A gripper assembly 42 is installed below the housing 4. The gripper assembly 42 is a key component for gripping the template; it can flexibly extend, retract, and move to adapt to the gripping needs of templates in different positions. Below the gripper assembly 42, a first template placement part 44 and a second template placement part 45 are distributed sequentially. These two template placement parts provide temporary storage locations for the templates, ensuring stable placement during template changing and preventing the templates from falling or shifting. A tire assembly 481 is installed on one side of the gripper assembly 42. The tire assembly 481, through the interaction of its internal drive belt 4811 and positioning element 482, enables precise control of the gripper assembly 42, allowing it to move along a preset trajectory. Side plates 47 are installed on both sides of the first template placement part 44 and the second template placement part 45 respectively. The main function of the side plates 47 is to provide side support and protection for the template, prevent the template from being hit or squeezed by the side during placement or replacement, thereby ensuring the integrity and safety of the template.

[0031] The tire assembly 481 is a crucial component of the entire mechanism. It includes a drive belt 4811 and a positioning element 482. The drive belt 4811 runs through the positioning element 482, a design that ensures stable movement of the drive belt 4811 under the guidance of the positioning element 482, thus guaranteeing the motion accuracy and reliability of the entire tire assembly 481. A tire drive motor 48 is mounted above the tire assembly 481, providing power to the assembly. The motor's rotation drives the drive belt 4811 to move at a set speed and direction. When the tire assembly 481 moves, the drive belt 4811 moves accordingly, which in turn moves the positioning element 482 and its fixed gripper assembly 42. Driven by the tire assembly 481, the gripper assembly 42 extends forward, and its gripper 431 precisely grasps the corresponding hole on the template 52. Subsequently, the gripper assembly 42 pulls back inward, steadily placing the gripped template 52 onto the first template placement part 44 or the second template placement part 45. This process not only demonstrates the close cooperation between the tire assembly 481 and the gripper assembly 42, but also showcases the efficiency and automation of the entire mechanism during template replacement. Through the precise control of the tire assembly 481, the gripping and placement actions of the template can be completed accurately, greatly improving the efficiency and quality of template replacement and reducing the tediousness and errors of manual operation.

[0032] The gripper assembly 42 also features a clever and innovative structural design. It comprises an upper moving rail 422 and a lower moving rail 423, which work together to form the main frame of the gripper assembly 42. Both ends of the upper moving rail 422 and the lower moving rail 423 are convex, allowing them to fit tightly into the connector 424, thus ensuring the structural stability of the entire gripper assembly 42. Holes 4231 are specially designed on both sides of the lower moving rail 423's cross-section. These holes not only reduce the weight of the lower moving rail 423 but also provide space for the installation and movement of other components, making the overall structure of the gripper assembly 42 more compact and rational. The upper moving rail 422 and the lower moving rail 423 are fixed together by several connectors 424. The function of the connectors 424 is to tightly connect the upper moving rail 422 and the lower moving rail 423 together to form a whole. At the same time, the concave structure inside the connectors 424 can well accommodate the convex parts at both ends of the upper moving rail 422 and the lower moving rail 423, further enhancing the structural strength and stability of the gripper assembly 42. This unique structural design enables the gripper assembly 42 to maintain good rigidity and stability during movement, thereby more reliably completing the task of gripping and transporting the template. In addition, the gripper 431 on the gripper assembly 42 is the part that directly contacts the template, and its design accuracy and reliability directly affect the gripping effect of the template. Through reasonable structural design and precise manufacturing, the gripper 431 can accurately grasp the corresponding holes on the template, ensuring the stability and safety of the template during gripping and transport.

[0033] Although connector 424 appears to be a small component in the entire mechanism, it plays a crucial role. Connector 424 has a concave internal structure designed to better accommodate the convex portions at both ends of the upper moving rail 422 and the lower moving rail 423. When the convex portions of the upper and lower moving rails 422 and 423 are embedded in connector 424, they form a tight fit, thus firmly connecting the upper and lower moving rails 422 and 423 together. This connection method not only ensures the structural stability of the gripper assembly 42 but also allows the entire gripper assembly 422 to maintain good integrity during movement. The concave structure of connector 424 also has a certain elastic buffering effect. When the gripper assembly 422 is subjected to external impact during movement, connector 424 can absorb some of the impact energy through its own elastic deformation, thereby protecting the upper and lower moving rails 422 and 423 from damage and extending the service life of the entire gripper assembly 42. In addition, the number and distribution of the connectors 424 have been carefully designed to ensure that all parts of the gripper assembly 42 are adequately supported and fixed, thereby ensuring that the entire gripper assembly 42 can work stably and reliably under various working conditions.

[0034] A support arm 421 is fixed to the lower end of the lower moving rail 423. The main body of the support arm 421 has a trapezoidal structure, which gives it good mechanical properties and stability. A gripper driver 43 is fixed to each end of the support arm 421. The gripper driver 43 is the core component driving the movement of the gripper 431. Through its internal motor or other driving device, the gripper driver 43 can precisely control the opening and closing of the gripper 431, thereby achieving the gripping and releasing of the template. The gripper 431 is connected below the gripper driver 43. The gripper 431 is the part that directly contacts the template, and its design precision and reliability directly affect the gripping effect of the template. Through reasonable structural design and precise manufacturing, the gripper 431 can accurately grasp the corresponding holes on the template, ensuring the stability and safety of the template during gripping and handling. The structural design of the support arm 421 and the gripper actuator 43 not only ensures the stability and reliability of the gripper assembly 42 during movement, but also enables the gripper assembly 42 to perform template gripping and releasing actions more flexibly. Furthermore, the trapezoidal structure of the support arm 421 provides stable support for the gripper actuator 43, allowing it to maintain good working condition during operation, thereby further improving the overall working efficiency and reliability of the gripper assembly 42.

[0035] One side of the lower moving rail 423 is connected to the positioning element 482 on the tire assembly 481. This connection method creates a close linkage between the gripper assembly 42 and the tire assembly 481. When the tire assembly 481 moves, the lower moving rail 423 moves accordingly through the positioning element 482, enabling the entire gripper assembly 42 to move along a preset trajectory. This linkage not only ensures the movement accuracy and reliability of the gripper assembly 42 but also makes the entire template changing mechanism's operation more coordinated and smooth. Through the close cooperation between the tire assembly 481 and the gripper assembly 42, the template can be quickly gripped and accurately placed, greatly improving the efficiency and quality of template changing. In addition, this connection method makes the entire mechanism's structure more compact and reasonable, reducing space occupation and improving the equipment's integration and flexibility.

[0036] Both the first template placement section 44 and the second template placement section 45 have continuous trapezoidal cross-sections 46. This continuous trapezoidal cross-section design gives the template placement section excellent load-bearing capacity and stability. The trapezoidal cross-section structure provides stable support for the template, preventing slippage or displacement during placement. Simultaneously, the continuous trapezoidal cross-section structure ensures the surface flatness and smoothness of the template placement section, thereby reducing frictional resistance during placement and removal and improving template replacement efficiency. Furthermore, this structural design allows for flexible adjustment based on the size and shape of the template to meet different template placement requirements. Through reasonable design and optimization, the first template placement section 44 and the second template placement section 45 provide a safe, stable, and reliable storage location for the template, ensuring the integrity and safety of the template during replacement.

[0037] Several side plate drive motors 471 are provided on one side of the housing 4, and a connecting rod 472 is provided below the side plate 47. The side plate drive motor 471 is the core component that drives the movement of the side plate 47. Through its internal motor or other drive device, it can precisely control the retraction and expansion of the side plate 47. The side plate drive motor 471 drives the connecting rod 472 below the side plate 47 to move, thereby realizing the retraction and expansion of the side plate 47. The retraction and expansion of the side plate 47 plays a crucial role in the template replacement process. When it is necessary to grasp the template 52, the side plate 47 can retract back between the first template placement part 44 and the second template placement part 45, thereby providing sufficient space for the movement of the gripper assembly 42, enabling it to smoothly grasp the template 52. When the template is placed on the first template placement part 44 or the second template placement part 45, the side plate 47 can expand to provide lateral support and protection for the template, preventing the template from being impacted or squeezed from the side. The retraction and expansion function of this side plate 47 not only improves the efficiency and flexibility of template replacement, but also enhances the safety of the template during placement. Through the precise control of the side plate drive motor 471 and connecting rod 472, the side plate 47 can achieve rapid and accurate retraction and expansion, thereby ensuring the normal operation of the entire template replacement mechanism.

[0038] An operating platform 5 is located on one side of the transport vehicle. The operating platform 5 is the core area for operators to perform operations and controls, providing a comfortable and convenient operating environment. A template fixing component 51 is installed on the operating platform 5. The template fixing component 51 securely fixes the template to the operating platform, preventing movement or shaking during operation, thus ensuring accuracy and safety. A telescopic part 3 and a movable part 2 are located on the upper part of the housing 4. These are key components for realizing the movement and position adjustment of the transport vehicle. The telescopic part 3 controls the telescopic movement of the entire transport vehicle. Through the telescopic movement of the telescopic part 3, the transport vehicle can flexibly adjust its telescopic movement according to actual production needs and template replacement positions, thereby achieving rapid and accurate grasping and placement of templates. The movable part 2 drives the movement of the entire transport vehicle. Through the movement of the movable part 2, the transport vehicle can move horizontally on the production line, thereby realizing the replacement operation of templates at different positions. Above the moving part 2 is the top rail 1, which provides stable track support for the movement of the transport vehicle, ensuring its stability and accuracy during movement. Through the cooperation of the telescopic part 3, the moving part 2, and the top rail 1, the transport vehicle can achieve flexible movement and position adjustment, thereby greatly improving the efficiency and flexibility of template replacement. In addition, this structural design of the operating table 5, template fixing assembly 51, telescopic part 3, and moving part 2 makes the operation of the entire transport vehicle template replacement mechanism more convenient and user-friendly. Operators can easily perform telescopic, moving, and template replacement operations on the transport vehicle through the control buttons or operating interface on the operating table 5, greatly improving production efficiency and equipment usability.

[0039] The shell 4 is provided with several shell reinforcing ribs 41. The function of the shell reinforcing ribs 41 is to enhance the structural strength and stability of the shell 4. During the operation of the transport vehicle template changing mechanism, the shell 4 needs to withstand various external forces, such as the impact force of the gripper assembly 42 and the weight of the template. The shell reinforcing ribs 41 can effectively improve the compressive strength and bending strength of the shell 4, thereby ensuring that the shell 4 can maintain good structural stability under various working conditions. Through reasonable design and arrangement, the shell reinforcing ribs 41 can evenly distribute the external forces borne by the shell 4 to the entire shell structure, preventing excessive local stress that could lead to deformation or damage to the shell 4. In addition, the shell reinforcing ribs 41 can also improve the rigidity of the shell 4, reduce the vibration and deformation of the shell 4 during movement, thereby ensuring the operating accuracy and reliability of the entire transport vehicle template changing mechanism.

[0040] Example 2: Refer to Figures 1 to 7A template changing mechanism for a transport vehicle includes a core structure comprising a housing 4. The housing 4 plays a crucial role in load-bearing and protection within the entire mechanism, providing a stable mounting space for the various internal components and resisting external interference and impacts to ensure the normal operation of the entire mechanism. The housing 4 is typically designed using high-strength materials to ensure its durability and stability in harsh environments. Furthermore, the internal structure of the housing 4 is meticulously designed to ensure a rational layout and efficient operation of the various components.

[0041] A gripper assembly 42 is installed at the bottom of the housing 4. The gripper assembly 42 is a key component for template gripping; it can flexibly extend, retract, and move to adapt to the gripping needs of templates in different positions. The gripper assembly 42 is typically designed with multiple movable joints and drive mechanisms, enabling it to accurately position and grip the template. This flexibility allows the gripper assembly 42 to efficiently complete tasks in complex environments, reducing the need for manual operation and improving work efficiency.

[0042] Below the gripper assembly 42, a first template placement section 44 and a second template placement section 45 are arranged sequentially. These two template placement sections provide temporary storage locations for the templates, ensuring stable placement during template replacement and preventing the templates from falling or shifting. The design of the template placement sections typically takes into account the size and shape of the templates to ensure they can be placed securely. Furthermore, the surfaces of the template placement sections are usually specially treated to reduce frictional resistance during placement and removal, further improving template replacement efficiency.

[0043] A pulley assembly 481 is mounted on one side of the gripper assembly 42. Through the interaction of its internal drive belt 4811 and positioning element 482, the pulley assembly 481 enables precise control of the gripper assembly 42, allowing it to move along a preset trajectory. The design of the pulley assembly 481 not only improves the motion accuracy of the gripper assembly 42 but also enhances the automation level of the entire mechanism. Through precise control, the pulley assembly 481 ensures the stability of the gripper assembly 42 during complex movements, thereby improving the reliability and efficiency of template replacement.

[0044] Side plates 47 are installed on both sides of the first template placement section 44 and the second template placement section 45. The main function of the side plates 47 is to provide lateral support and protection for the template, preventing it from being impacted or squeezed during placement or replacement, thereby ensuring the integrity and safety of the template. The design of the side plates 47 usually takes into account the size and shape of the template to ensure that it can provide sufficient support and protection. In addition, the material of the side plates 47 usually has good wear resistance and impact resistance to ensure its durability in long-term use.

[0045] The tire assembly 481 includes a drive belt 4811 and a positioning element 482. The drive belt 4811 passes through the positioning element 482. This structural design allows the drive belt 4811 to move stably under the guidance of the positioning element 482, thereby ensuring the motion accuracy and reliability of the entire tire assembly 481. The positioning element 482 is typically designed to include multiple guide pulleys and support structures to ensure that the drive belt 4811 always stays on the correct track during movement.

[0046] A belt drive motor 48 is mounted above the belt assembly 481. The belt drive motor 48 provides power to the belt assembly 481, driving the belt 4811 to move at a set speed and direction. The selection of the belt drive motor 48 typically considers its power, torque, and control precision to ensure efficient and stable operation of the belt assembly 481. Furthermore, the belt drive motor 48 is equipped with an advanced control system that enables precise speed and position control, further enhancing the automation level of the belt assembly 481.

[0047] When the pulley assembly 481 moves, the drive belt 4811 moves accordingly, which in turn drives the positioning component 482 and its fixed gripper assembly 42 to move. Driven by the pulley assembly 481, the gripper assembly 42 extends forward, at which point the gripper 431 on the gripper assembly 42 precisely grasps the corresponding hole on the template 52. Subsequently, the gripper assembly 42 pulls back inward, steadily placing the grasped template 52 onto the first template placement part 44 or the second template placement part 45. This process not only demonstrates the close cooperation between the pulley assembly 481 and the gripper assembly 42, but also showcases the efficiency and automation of the entire mechanism during template replacement.

[0048] The precise control of the tire assembly 481 ensures accurate and error-free template gripping and placement, significantly improving the efficiency and quality of template replacement and reducing the tediousness and errors of manual operation. Furthermore, the design of the tire assembly 481 also considers ease of maintenance and upkeep. Through a rational structural and modular design, maintenance and replacement of the tire assembly 481 are more convenient and faster, further improving the reliability and service life of the equipment.

[0049] The gripper assembly 42 includes an upper moving rail 422 and a lower moving rail 423. These two parts work together to form the main frame of the gripper assembly 42. Both ends of the upper moving rail 422 and the lower moving rail 423 are convex. This convex structure design allows them to fit tightly with the connector 424, thus ensuring the structural stability of the entire gripper assembly 42. The convex structure design not only improves the structural strength of the gripper assembly 42 but also enables it to maintain good rigidity and stability during movement, thereby more reliably completing the tasks of gripping and transporting templates.

[0050] Holes 4231 are specially designed on both sides of the cross-section of the lower moving rail 423. These holes 4231 not only reduce the weight of the lower moving rail 423, but also provide space for the installation and movement of other components, making the structure of the entire gripper assembly 42 more compact and reasonable. This design not only optimizes the structure of the gripper assembly 42, but also improves its flexibility and efficiency of movement. In addition, the design of the holes 4231 also takes into account the needs of heat dissipation and vibration reduction. Through reasonable layout and design, the gripper assembly 42 can maintain good performance during long-term operation.

[0051] The upper moving rail 422 and the lower moving rail 423 are fixed together by several connectors 424. The function of the connectors 424 is to tightly connect the upper moving rail 422 and the lower moving rail 423 together to form a whole. The connectors 424 are typically made of high-strength materials and are precisely machined and assembled to ensure that they can withstand the various forces generated by the gripper assembly 42 during movement. In addition, the concave structure inside the connectors 424 can well accommodate the convex parts at both ends of the upper moving rail 422 and the lower moving rail 423, further enhancing the structural strength and stability of the gripper assembly 42. This unique structural design enables the gripper assembly 42 to maintain good rigidity and stability during movement, thereby more reliably completing the tasks of gripping and transporting templates.

[0052] The gripper 431 on the gripper assembly 42 is the part that directly contacts the template, and its design precision and reliability directly affect the gripping effect of the template. Through reasonable structural design and precise manufacturing, the gripper 431 can accurately grasp the corresponding holes on the template, ensuring the stability and safety of the template during gripping and handling. The design of the gripper 431 usually takes into account the size and shape of the template to ensure that it can adapt to different types of templates. In addition, the gripper 431 is also equipped with advanced sensors and control systems, which can monitor the force and position information in real time during the gripping process, thereby achieving precise gripping and placement.

[0053] The connector 424 has a concave internal structure, designed to better accommodate the convex portions at both ends of the upper moving rail 422 and the lower moving rail 423. When the convex portions of the upper moving rail 422 and the lower moving rail 423 are embedded in the connector 424, they form a tight fit, thus firmly connecting the upper moving rail 422 and the lower moving rail 423 together. This connection method not only ensures the structural stability of the gripper assembly 42, but also allows the entire gripper assembly 42 to maintain good integrity during movement.

[0054] The concave structure of the connector 424 also has a certain elastic buffering effect. When the gripper assembly 42 is subjected to external impact during movement, the connector 424 can absorb part of the impact energy through its own elastic deformation, thereby protecting the upper moving rail 422 and the lower moving rail 423 from damage and extending the service life of the entire gripper assembly 42. In addition, the number and distribution of the connectors 424 have also been carefully designed to ensure that all parts of the gripper assembly 42 can be fully supported and fixed, thereby ensuring that the entire gripper assembly 42 can work stably and reliably under various working conditions.

[0055] The design of connector 424 typically takes into account the strength and modulus of elasticity of its material to ensure it maintains good performance during long-term use. Furthermore, the surface of connector 424 is usually specially treated to improve its wear resistance and corrosion resistance, further extending its service life. Through reasonable structural design and material selection, connector 424 not only improves the structural stability of gripper assembly 42 but also enhances the reliability and durability of the entire mechanism.

[0056] A support arm 421 is fixed to the lower end of the lower moving rail 423. The main body of the support arm 421 is a trapezoidal structure, which gives the support arm 421 good mechanical properties and stability. The design of the support arm 421 typically takes into account its load-bearing capacity and structural strength to ensure that it can maintain good performance during long-term operation. The trapezoidal structure design not only improves the structural strength of the support arm 421, but also enables it to better distribute and bear the various forces generated by the gripper assembly 42 during movement.

[0057] At each end of the support arm 421 is a gripper driver 43, which is the core component driving the movement of the gripper 431. The gripper driver 43, through its internal motor or other drive device, can precisely control the movement of the gripper 431, thereby achieving the gripping and releasing of the template. The design of the gripper driver 43 typically considers its control accuracy and reliability to ensure that the gripper 431 can accurately complete the gripping and releasing actions. Furthermore, the gripper driver 43 is equipped with advanced sensors and a control system that can monitor the position and status of the gripper 431 in real time, thereby achieving precise control.

[0058] Below the gripper actuator 43 is the gripper 431, which is the part that directly contacts the template. Its design precision and reliability directly affect the template gripping effect. Through reasonable structural design and precise manufacturing, the gripper 431 can accurately grasp the corresponding holes on the template, ensuring the stability and safety of the template during gripping and handling. The design of the gripper 431 typically takes into account the size and shape of the template to ensure it can adapt to different types of templates. Furthermore, the gripper 431 is equipped with advanced sensors and a control system that can monitor force and position information in real time during the gripping process, thereby achieving precise gripping and placement.

[0059] The structural design of the support arm 421 and the gripper actuator 43 not only ensures the stability and reliability of the gripper assembly 42 during movement, but also enables the gripper assembly 42 to perform template gripping and releasing actions more flexibly. Furthermore, the trapezoidal structure of the support arm 421 provides stable support for the gripper actuator 43, allowing it to maintain good working condition during operation, thereby further improving the overall working efficiency and reliability of the gripper assembly 42.

[0060] One side of the lower moving rail 423 is connected to the positioning element 482 on the tire assembly 481. This connection method creates a close linkage between the gripper assembly 42 and the tire assembly 481. When the tire assembly 481 moves, the lower moving rail 423 moves accordingly through the positioning element 482, thus enabling the entire gripper assembly 42 to move along a preset trajectory. This linkage not only ensures the motion accuracy and reliability of the gripper assembly 42, but also makes the entire template changing mechanism's operation more coordinated and smooth.

[0061] The tight fit between the tire assembly 481 and the gripper assembly 42 enables rapid gripping and precise placement of the template, significantly improving the efficiency and quality of template replacement. Furthermore, this connection method makes the entire mechanism more compact and rational, reducing space occupation and improving the integration and flexibility of the equipment. In practical applications, this close linkage ensures that the gripper assembly 42 remains stable throughout complex movements, thereby improving the reliability and efficiency of template replacement.

[0062] Both the first template placement section 44 and the second template placement section 45 have continuous trapezoidal cross-sections 46. This continuous trapezoidal cross-section design gives the template placement section good load-bearing capacity and stability. The trapezoidal cross-section structure provides stable support for the template, preventing slippage or displacement during placement. Furthermore, the continuous trapezoidal cross-section structure ensures the surface flatness and smoothness of the template placement section, thereby reducing frictional resistance during placement and removal and improving template replacement efficiency.

[0063] Several side plate drive motors 471 are arranged on one side of the housing 4, and a connecting rod 472 is arranged below the side plate 47. The side plate drive motor 471 is the core component that drives the movement of the side plate 47. Through its internal motor or other drive device, it can precisely control the retraction and expansion of the side plate 47. The design of the side plate drive motor 471 usually takes into account its control accuracy and reliability to ensure that the side plate 47 can accurately complete the retraction and expansion actions.

[0064] The side plate drive motor 471 drives the connecting rod 472 below the side plate 47 to move, thereby realizing the retraction and expansion of the side plate 47, which can smoothly grasp the template 52. When the template is placed on the first template placement part 44 or the second template placement part 45, the side plate 47 unfolds to provide side support and protection for the template, preventing the template from being hit or squeezed from the side.

[0065] The retraction and expansion function of this side plate 47 not only improves the efficiency and flexibility of template replacement but also enhances the safety of the template during placement. Through precise control of the side plate drive motor 471 and connecting rod 472, the side plate 47 can achieve rapid and accurate retraction and expansion, thus ensuring the normal operation of the entire template replacement mechanism. Furthermore, the design of the side plate 47 typically considers the strength and modulus of elasticity of its material to ensure it maintains good performance during long-term use. Through reasonable structural design and material selection, the side plate 47 not only improves the safety of template placement but also enhances the reliability and durability of the entire mechanism.

[0066] An operating platform 5 is installed on one side of the transport vehicle. The operating platform 5 is the core area for operators to perform operations and controls, providing a comfortable and convenient operating environment. A template fixing component 51 is installed on the operating platform 5. The function of the template fixing component 51 is to firmly fix the template to the operating platform, preventing the template from moving or shaking during operation, thereby ensuring the accuracy and safety of the operation. The design of the template fixing component 51 typically considers its fixing force and reliability to ensure that the template remains stable during operation.

[0067] The upper part of the housing 4 is equipped with a telescopic section 3 and a movable section 2, which are key components for realizing the movement and position adjustment of the transport vehicle. The telescopic section 3 controls the telescopic movement of the entire transport vehicle. Through the telescopic movement of the telescopic section 3, the transport vehicle can flexibly adjust its telescopic position according to actual production needs and template replacement, thereby achieving rapid and accurate grasping and placement of the template. The design of the telescopic section 3 typically considers its telescopic range and accuracy to ensure that the transport vehicle can flexibly complete its tasks under various working conditions.

[0068] The moving part 2 drives the movement of the entire transport vehicle. Through the movement of the moving part 2, the transport vehicle can move horizontally on the production line, thereby enabling the replacement of templates at different positions. The design of the moving part 2 typically considers its speed and precision to ensure that the transport vehicle can operate efficiently and stably on the production line. Above the moving part 2 is the top track 1, which provides stable track support for the movement of the transport vehicle, ensuring its smoothness and accuracy during movement.

[0069] The shell 4 is provided with several shell reinforcing ribs 41. The function of the shell reinforcing ribs 41 is to enhance the structural strength and stability of the shell 4. During the operation of the transport vehicle template changing mechanism, the shell 4 needs to withstand various external forces, such as the impact force of the gripper assembly 42 and the weight of the template. The shell reinforcing ribs 41 can effectively improve the compressive strength and bending strength of the shell 4, thereby ensuring that the shell 4 can maintain good structural stability under various working conditions.

[0070] Through reasonable design and arrangement, the shell reinforcing ribs 41 can evenly distribute the external forces borne by the shell 4 across the entire shell structure, preventing excessive local stress that could lead to deformation or damage to the shell 4. Furthermore, the installation of the shell reinforcing ribs 41 can also improve the rigidity of the shell 4, reducing vibration and deformation during movement, thereby ensuring the operational accuracy and reliability of the entire transport vehicle template changing mechanism. The design of the shell reinforcing ribs 41 typically considers the strength and elastic modulus of the material to ensure good performance during long-term use. Through reasonable structural design and material selection, the shell reinforcing ribs 41 not only improve the structural strength of the shell 4 but also enhance the reliability and durability of the entire mechanism.
