Description

Technical Field

[0001] This invention relates to the field of battery processing, and more particularly, to a high-speed assembly line for cylindrical battery cover plates. Background Technology

[0002] Cylindrical lithium-ion batteries are widely used in new energy vehicles, power tools, energy storage systems, and various consumer electronics products due to their advantages such as high energy density, relatively controllable cost, and mature manufacturing processes. As a key safety component of the battery, the battery cover plays multiple crucial roles, including sealing the battery cell, preventing electrolyte leakage, providing insulation and conductivity for the electrode terminals, and serving as a pressure relief channel for the safety valve. In the production process of battery covers, traditional assembly methods often suffer from the following drawbacks: the loading, alignment, and pressing of the cover, collar, and plug rely heavily on manual labor or semi-automatic equipment, resulting in slow speeds that cannot meet the demands of large-scale production. Furthermore, the continuously rising labor costs hinder mass production. Summary of the Invention

[0003] In view of this, the present invention provides a high-speed assembly line for cylindrical battery cover plates that can achieve fully automated assembly and significantly improve assembly speed.

[0004] The objective of this invention is achieved through the following technical solution: A high-speed assembly line for cylindrical battery cover plates includes: A cover feeding device includes a cover storage area and a cover feeding area, wherein the cover feeding area is used to transport covers in the cover storage area; A collar feeding device is provided adjacent to the cover feeding device for conveying collars; A rubber stopper feeding device is used to transport rubber stoppers; The cover plate assembly device is connected to the cover body feeding device, the collar feeding device and the rubber stopper feeding device, and is used to assemble the cover body, collar and rubber stopper into a finished cover plate; The finished product inspection device is connected to the cover plate assembly device and is used to inspect the surface and sides of the finished cover plate and classify and store the defective products detected. The cover plate storage device includes a dual-disc switching mechanism and a finished product storage area. The dual-disc switching mechanism is connected to the finished product detection device and is used to temporarily store the finished cover plate. The finished product storage area is used to store the finished cover plate.

[0005] In the above technical solution, the assembly line integrates automatic feeding, automatic assembly, automatic testing and automatic storage functions for the cover body, collar and rubber stopper, realizing full automation of the cover plate production process, greatly reducing manual intervention and operation links, and significantly improving production efficiency and capacity.

[0006] The automated assembly process using a cover plate assembly device avoids errors and damage caused by manual operation, ensuring precise fit and stable assembly quality between the cover body, collar, and rubber stopper, resulting in good product consistency. It is also equipped with a finished product inspection device that automatically inspects the surface and sides of the finished cover plates and automatically classifies and stores defective products. Furthermore, the cover plate storage device, employing a dual-tray switching mechanism, can receive cover plates in real time after finished product inspection and automatically and seamlessly switch to an empty tray when one tray is full. Simultaneously, it allows operators to safely remove full trays and place empty trays, achieving a "zero-downtime" switching process for finished product delivery.

[0007] Optionally, in one possible implementation, the collar feeding device includes: Vibratory feeder with collar; A buffer transfer mechanism includes a buffer conveyor belt and a transfer component. The input end of the buffer conveyor belt is connected to the output end of the ring vibrating plate for receiving and buffering multiple rings. The transfer component is located below the buffer conveyor belt. A dispensing mechanism includes a dispensing table and a dispensing assembly. The dispensing table is provided with a clearance channel. The transfer assembly is movably inserted into the clearance channel and is capable of simultaneously transferring multiple collars located on the buffer conveyor belt to the dispensing table. The dispensing assembly is located on one side of the dispensing table and is used to dispense adhesive onto the collars located on the dispensing table. The ring conveyor belt has its input end connected to the dispensing station and its output end connected to the cover plate assembly device.

[0008] In the above technical solution, the transfer component can simultaneously move multiple loops from the buffer conveyor belt to the dispensing table, significantly increasing the throughput of a single operation and greatly improving overall production efficiency, making it particularly suitable for mass production scenarios. An obstacle avoidance channel is set on the dispensing table, through which the transfer component performs the transfer operation from below. This cleverly solves the problem of spatial interference between the robotic arm and the dispensing component when traditionally grasping or transferring from above. It eliminates the need for complex obstacle avoidance paths or waiting times, resulting in a compact structure and optimized space layout.

[0009] Optionally, in one possible implementation, the transfer assembly includes a collar drive module, a movable seat disposed at the output end of the collar drive module, and a liftable support block, the support block being movable in the clearance channel, and the support block being mounted on the movable seat by a plurality of lifting drive components.

[0010] In the above technical solution, the collar drive module ensures that the moving seat and support block can be moved accurately and quickly to the designated position below the buffer conveyor belt and the target position on the dispensing table. The liftable support block design lifts up to directly support the bottom of multiple collars arranged on the buffer conveyor belt to drive their movement, and then lowers to place the collars smoothly and accurately at the predetermined position on the dispensing table. This cleverly fits the obstacle avoidance channel design and achieves interference-free operation.

[0011] Optionally, in one possible implementation, the cover plate assembly device includes: frame; An assembly mechanism, mounted on the frame, includes a first turret suction assembly, a second turret suction assembly, and a central turntable located between the two. The cover conveyor turntable is connected to the cover feeding device and the first turret suction assembly; The collar conveyor turntable is connected to the collar feeding device and the first turret suction assembly; A rubber stopper conveying turntable is connected to the rubber stopper feeding device and the second turret suction assembly; The discharge conveyor turntable is connected to the second turret suction assembly; The first turret suction assembly is used to assemble the cover and collar, and the assembled semi-finished product is transferred to the transfer turntable; the second turret suction assembly is used to assemble the rubber stopper and semi-finished product, and the assembled finished product is transferred to the discharge conveyor turntable.

[0012] In the above technical solution, by utilizing the continuous rotation characteristics of the first and second turret suction components, suction, placement, and assembly actions can be performed simultaneously at multiple workstations, achieving parallel operation at multiple workstations. The intermediate turntable acts as a buffer and transition, effectively connecting the assembly of the cover and collar in the first process and the assembly of the rubber stopper in the second process. This allows the two main assembly steps to operate independently, continuously, and efficiently, avoiding mutual waiting and significantly improving overall cycle time and production efficiency.

[0013] Optionally, in one possible implementation, the first turret suction assembly and the second turret suction assembly have the same structure, both including: A rotating shaft is rotatably mounted on the frame. The valve control assembly includes an intake cover plate fixed to the frame, an air guide plate fixed to the outer periphery of the rotating shaft and abutting against the intake cover plate, and a plurality of air guide pipes disposed on the air guide plate and arranged around the rotating shaft. The material handling assembly includes a turntable and a plurality of suction pipes mounted on the turntable, each suction pipe being connected to a corresponding air guide pipe; The air intake cover is provided with an air intake nozzle and a ventilation groove communicating with the air intake nozzle; when the rotating shaft rotates, it drives the air guide plate and air guide pipe to rotate relative to the air intake cover, so that each of the air guide pipes passes through the ventilation groove in sequence.

[0014] In the above technical solution, the rotating air guide plate and air guide pipe assembly move relative to the fixed air inlet cover, and the air passage is switched on and off through the air groove on the physical contact surface. Only the air guide pipe currently aligned with the air groove is connected to the vacuum source, while the air guide pipes in other positions are effectively blocked by the air guide plate and are in a disconnected airflow state. In this way, it is not necessary to equip each suction pipe with an independent solenoid valve. The suction and release actions of the suction pipe are automatically determined by whether it passes through the air groove during rotation, making the suction and release actions more precise and the structure simpler.

[0015] Optionally, in one possible implementation, an upper guide cam is also fixed on the frame, and an upper cam groove is provided on the outer periphery of the upper guide cam. The air intake pipe is movably engaged in the upper cam groove through an upper guide wheel.

[0016] In the above technical solution, when the rotating shaft drives the suction assembly to rotate, the upper guide wheel fixed on the suction pipe is forced to move along the trajectory of the upper cam groove. The change in the depth of the groove forces the guide wheel to produce a precise upward or downward movement in the vertical direction to facilitate material suction. This eliminates the need to install a separate cylinder or electric cylinder at each suction pipe location for lifting, simplifying the structure and reducing costs.

[0017] Optionally, in one possible implementation, the finished product testing device includes: The material conveyor belt is used to receive the finished cover plates from the cover plate assembly device; A surface inspection mechanism, connected to the incoming material conveyor belt, is used to inspect the surface of the finished product; A side inspection mechanism is disposed adjacent to the surface inspection mechanism and is used to inspect the circumferential side of the finished product; The transfer mechanism includes a transfer bracket, a rotary drive assembly mounted on the transfer bracket, and a plurality of material picking components connected to the output end of the rotary drive assembly; the rotary drive assembly is used to drive the material picking components to perform circular motion. A defective product sorting mechanism is located adjacent to the transfer mechanism for receiving, sorting, and storing defective products; Discharge conveyor belt; The surface inspection mechanism, the side inspection mechanism, the defective product classification mechanism, and the discharge conveyor belt are arranged sequentially along the circumferential motion path of the material handling assembly.

[0018] In the above technical solution, by setting up a surface inspection mechanism and a side inspection mechanism, the surface and circumferential side of the cylindrical battery cover assembly are inspected respectively, which can realize a comprehensive quality inspection of the finished product, effectively avoid defects that are missed due to a single inspection angle, and improve the overall quality stability of the product.

[0019] Optionally, in one possible implementation, the surface inspection mechanism includes a finished product conveying turntable and a plurality of first vision inspection modules arranged sequentially and at intervals along the outer periphery of the finished product conveying turntable; the side inspection mechanism includes an inspection bracket and a plurality of second vision inspection modules, wherein the inspection bracket is provided with an inspection station, and the plurality of second vision inspection modules are arranged at intervals around the inspection station.

[0020] In the above technical solution, the arrangement of multiple first-vision inspection modules ensures that the entire surface of each battery cover can be captured multiple times by cameras at different positions and angles as it rotates through the inspection area, effectively eliminating blind spots from a single perspective. Multiple second-vision inspection modules are spaced around the inspection station, forming a multi-angle, all-around vision inspection ring. The entire circumferential side of the battery cover can be captured by all the surrounding second-vision inspection modules.

[0021] Optionally, in one possible implementation, the defective product sorting mechanism includes two sets of symmetrically arranged storage mechanisms and a distributing mechanism located between the two sets of storage mechanisms; The material storage mechanism includes a conveying component, a pushing component, and a storage component. The pushing component and the storage component are respectively disposed on both sides of the conveying component in the conveying direction. The pushing component is located at the output end of the conveying component and is used to push the material from the conveying component to the storage component. The material distribution mechanism includes a rotary drive and a material distribution plate. The material distribution plate is connected to the output end of the rotary drive and has two discharge ends. The rotary drive is used to drive the material distribution plate to rotate and swing so that one of the two discharge ends can be connected to the input end of the corresponding material conveying component in the two sets of material storage mechanisms.

[0022] In the above technical solution, two sets of symmetrically arranged storage mechanisms can simultaneously receive and process defective products from the transfer mechanism, realizing parallel operation of dual channels. Repairable and defective products are separated from irreparable defective products, thus eliminating the need for manual screening of defective products and greatly improving sorting efficiency.

[0023] Optionally, in one possible implementation, the dual-disc switching mechanism includes a material rack, a first material tray and a second material tray disposed on the material rack, and a switching drive component. The material rack is provided with a first guide rail and a second guide rail located below the first guide rail. The first material tray and the second material tray are slidably disposed on the first guide rail and the second guide rail, respectively. The switching drive component can synchronously drive the first material tray and the second material tray to move in opposite directions on the first guide rail and the second guide rail, respectively.

[0024] In the above technical solution, the dual material trays are synchronously driven to move in opposite directions along the upper and lower guide rails by a switching drive component, achieving rapid switching between dual workstations. When the first material tray is in the processing position, the second material tray can be unloaded simultaneously, which can significantly reduce equipment waiting time and improve production cycle time. The first and second guide rails adopt an upper and lower layered structure, so that the switching of the two material trays will not cause motion interference, and can effectively reduce the lateral space occupied by the mechanism.

Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0048] Please refer to Figure 1 This embodiment provides a high-speed assembly line for cylindrical battery covers, including: a cover feeding device A, a collar feeding device B, a rubber stopper feeding device C, a cover assembly device D, a finished product inspection device E, and a cover storage device F; the cover feeding device A includes a cover storage area a1 and a cover feeding area a2, the cover feeding area a2 being used to transport covers from the cover storage area a1; the collar feeding device B is located adjacent to the cover feeding device A and is used to transport collars; the rubber stopper feeding device C is used to transport rubber stoppers; the cover assembly device... Device D connects to the cover feeding device A, the collar feeding device B, and the rubber stopper feeding device C, and is used to assemble the cover, collar, and rubber stopper into a finished cover plate. Device E connects to the cover plate assembly device D, and is used to inspect the surface and sides of the finished cover plate, and to classify and store the defective products. The cover plate storage device F includes a dual-disc switching mechanism f1 and a finished product storage area. The dual-disc switching mechanism f1 connects to the finished product inspection device E and is used to temporarily store the finished cover plates. The finished product storage area is used to store the finished cover plates.

[0049] The cover storage area a1 is equipped with multiple storage boxes. A multi-axis robot b321, in conjunction with a suction cup, picks up the covers located in the storage boxes and transfers them to the cover loading area a2. The cover loading area a2 is equipped with a cover conveyor belt, which transports the covers to the cover assembly device D. The rubber stopper loading device C includes a rubber stopper vibratory plate and a rubber stopper conveyor belt connected to the vibratory plate, which transports the rubber stoppers to the cover assembly device D.

[0050] The assembly line in this embodiment integrates automatic feeding, automatic assembly, automatic testing, and automatic storage functions for the cover body, collar, and rubber stopper, realizing full automation of the cover plate production process, greatly reducing manual intervention and operation links, and significantly improving production efficiency and capacity.

[0051] The automated assembly process using the cover assembly device D avoids errors and damage caused by manual operation, ensuring precise fit and stable assembly quality between the cover body, collar, and rubber stopper, resulting in good product consistency. It is also equipped with a finished product inspection device E, which automatically inspects the surface and sides of the finished cover and automatically classifies and stores defective products. Furthermore, the cover storage device F, employing a dual-tray switching mechanism f1, can receive cover plates in real time after finished product inspection and automatically and seamlessly switch to an empty tray when one tray is full. Simultaneously, it allows operators to safely remove full trays and place empty trays, achieving a "zero-downtime" switching process for finished product delivery.

[0052] Before assembling the collar with the cover, the collar needs to be glued to ensure the stability of the assembly between the collar and the cover. The collar feeding device B of this embodiment includes: a collar vibratory feeder b1, a buffer transfer mechanism b2, a dispensing mechanism b3, and a collar conveyor belt arranged sequentially along the collar conveying direction; the buffer transfer mechanism b2 includes a buffer conveyor belt b21 and a transfer component b22, the input end of the buffer conveyor belt b21 is connected to the output end of the collar vibratory feeder b1, and is used to receive and buffer multiple collars; the transfer component b22 is located below the buffer conveyor belt b21; the dispensing mechanism b3 includes a dispensing table b31 and a dispensing component b32, the dispensing table b31 is provided with a clearance channel, the transfer component b22 is movably inserted in the clearance channel, and can simultaneously transfer multiple collars located on the buffer conveyor belt b21 to the dispensing table b31; the dispensing component b32 is located on one side of the dispensing table b31 and is used to dispense glue onto the collars located on the dispensing table b31; the input end of the collar conveyor belt is connected to the dispensing table b31, and the output end is connected to the cover plate assembly device D.

[0053] The transfer component b22 can simultaneously transfer multiple loops from the buffer conveyor belt b21 to the dispensing table b31, significantly increasing the throughput of a single operation and greatly improving overall production efficiency, making it particularly suitable for mass production scenarios. An obstacle avoidance channel is provided on the dispensing table b31, through which the transfer component b22 passes for the transfer operation. This cleverly solves the problem of spatial interference between the robotic arm and the dispensing component b32 when traditionally grasping or transferring from above. It eliminates the need for complex obstacle avoidance paths or waiting times, resulting in a compact structure and optimized space layout. Furthermore, the buffer conveyor belt b21 serves as a buffer zone between the vibratory feeder and the transfer component b22. This effectively solves the problem of potential inconsistencies between the vibratory feeder output rate and the dispensing cycle time, ensuring a continuous and stable supply of loops for the dispensing process. It avoids waiting or idling of the dispensing equipment due to brief interruptions in feeding, guaranteeing the continuity and stability of the production line.

[0054] The buffer conveyor belt b21 includes two spaced-apart guide seats. Each guide seat has a groove on its opposite side, and a collar is movably engaged between the two grooves. A hollow channel is formed between the two guide seats, and the groove extends along the length of the guide seat. There is a certain gap between the groove and the collar to allow the collar to slide along the groove. Furthermore, the groove completely penetrates the guide seat, and its two ends are respectively connected to the feeding vibratory feeder and the buffer conveyor belt b21.

[0055] Two spaced-apart guide seats and their opposite side slots together form a physical guide channel. The two edges of the ferrule are constrained within the slots, ensuring that the ferrule maintains its preset posture and position while being conveyed on the buffer conveyor belt b21, effectively preventing tilting, flipping, or offset during transport. Simultaneously, the slot structure defines the independent operating space for each ferrule. The ferrules can only advance sequentially along the path defined by the slots, effectively avoiding the problems of ferrules stacking, jamming, or colliding randomly on the buffer conveyor belt b21.

[0056] The transfer component b22 in this embodiment includes a collar drive module b221, a movable frame b222 located at the output end of the collar drive module b221, and a liftable support block b223. ​​The support block b223 can move in the clearance channel, and the support block b223 is mounted on the movable frame b222 via several support drive components b224. The collar drive module b221 is a linear drive mechanism, such as a linear motor or linear guide rail. The support drive components b224 can be cylinders or electric actuators, etc.

[0057] The collar drive module b221 ensures that the moving frame b222 and support block b223 can move accurately and quickly to the designated position below the buffer conveyor belt b21 and the target position on the dispensing table b31. The liftable support block b223 is designed to lift up and directly support the bottom of multiple collars arranged on the buffer conveyor belt b21 to drive their movement, and then lower them to place the collars smoothly and accurately in the predetermined position on the dispensing table b31. This cleverly fits the avoidance channel design and achieves interference-free operation. This "transfer within the lower channel" mode completely solves the spatial conflict problem between the traditional feeding mechanism and the dispensing head. There is no need for complex avoidance path planning, waiting time, or additional flipping stations. The dispensing head can start dispensing immediately after the transfer component b22 descends and exits, without waiting for it to completely withdraw to the safe area, which significantly improves the overall operating efficiency and cycle time of the equipment.

[0058] The support drive component b224 is dedicated to controlling the lifting and lowering movement of the support block b223, and is functionally decoupled from the collar drive module b221, which is responsible for horizontal movement. It can precisely control the rising height of the support block b223 (ensuring that the collar is fully lifted out of the slot of the buffer conveyor belt b21) and the falling height (ensuring that the collar is stably placed on the dispensing table b31 and the support block b223 is completely retracted).

[0059] In addition, the top of the support base d261 is provided with multiple positioning grooves, which are spaced apart along the driving direction of the collar drive module b221. The collar can be placed on the positioning grooves. The shape of the positioning groove is an arc that matches the outer contour of the bottom of the collar, so as to fit tightly against the bottom edge of the collar. When the collar is lifted by the support block b223, its radial position is constrained by the side wall of the positioning groove, which effectively prevents the collar from sliding, rotating or shifting in the horizontal plane during the transfer process. Each collar is independently confined in its own positioning groove, ensuring that the collars will not collide or interfere with each other during high-speed transfer or start-stop.

[0060] In this embodiment, the dispensing table b31 is provided with a dispensing groove b33 for placing collars. The shape of the dispensing groove b33 is a recess that matches the outer contour of the collar, and multiple collars can be placed in the dispensing groove b33 at a preset interval. Specifically, the dispensing table b31 includes a fixed table b311 and a lifting table b312. The dispensing groove b33 includes a first groove b331 located on the fixed table b311 and multiple second grooves b332 located on the lifting table b312. The second grooves b332 are located below the first grooves b331. The support block b223 first moves the collar into the first groove b331, and then the lifting table b312 is lifted by the lifting cylinder b34 so that the collar is fitted into the corresponding second groove b332.

[0061] In this embodiment, the dispensing station b31 is also provided with a limiting mechanism b5. The limiting mechanism b5 includes a limiting drive member b51 disposed on the dispensing station b31 and a baffle b52 movably disposed on the dispensing station b31. The limiting drive member b51 is used to drive the baffle b52 to move above the dispensing groove b33. The limiting drive member b51 can be a cylinder or an electric cylinder. The limiting drive member b51 is fixed to one side of the dispensing station b31. The baffle b52 is connected to the output end of the limiting drive member b51, and the baffle b52 can slide on the top of the dispensing station b31 to cover or move away from the dispensing groove b33.

[0062] The baffle b52 is designed to block adhesive droplets from falling when the dispensing assembly b32 is not performing dispensing operations, preventing contamination of the collar and work station and improving the cleanliness of the dispensing environment. Furthermore, the bottom of the baffle b52 can be designed to make slight contact with the top of the collar or maintain a very small gap. When the baffle b52 covers the dispensing groove b33, a gentle axial limiting force is applied to the collar, creating a "clamping" effect with the radial constraint of the dispensing groove b33, further locking the collar and preventing radial runout.

[0063] The dispensing assembly b32 in this embodiment includes a dispensing robot b321, a mounting plate b322 disposed at the output end of the dispensing robot b321, and a plurality of dispensing guns b323 disposed on the mounting plate b322. The dispensing robot can be a six-axis robot or a precision XYZ three-axis module.

[0064] Multiple dispensing guns b323 are arranged at fixed intervals on the mounting plate b322, with their spacing precisely matching the positioning groove of the support block b223 and the collar spacing of the dispensing groove b33. This allows the dispensing robot to drive the entire assembly of dispensing guns b323 to simultaneously align with multiple collars on the dispensing groove b33, increasing efficiency several times over.

[0065] In this embodiment, the cover plate assembly device D includes: a frame d1, an assembly mechanism, a cover body conveying turntable d4, a collar conveying turntable d5, a rubber stopper conveying turntable d6, and a discharge conveying turntable d7; the assembly mechanism is mounted on the frame d1 and includes a first turret suction assembly e53d2, a second turret suction assembly e53d20, and an intermediate turntable d3 located between the two; the cover body conveying turntable d4 is connected to the cover body feeding device A and the first turret suction assembly e53d2; the collar conveying turntable d5 is connected to the collar... The feeding device B is connected to the first turret suction assembly e53d2; the rubber stopper conveying turntable d6 is connected to the rubber stopper feeding device C and the second turret suction assembly e53d20; the discharge conveying turntable d7 is connected to the second turret suction assembly e53d20; the first turret suction assembly e53d2 is used to assemble the cap and collar, and the assembled semi-finished product is transferred to the intermediate turntable d3; the second turret suction assembly e53d20 is used to assemble the rubber stopper and semi-finished product, and the assembled finished product is transferred to the discharge conveying turntable d7.

[0066] Specifically, the cover loading area a2 is equipped with a cover loading conveyor belt. The starting end of the cover loading conveyor belt is equipped with a gripping mechanism, which includes a gripping robot and multiple suction cups set at the output end of the gripping robot. The gripping robot drives the multiple suction cups to move into the material tray and simultaneously adsorbs multiple covers and moves them into the cover loading conveyor belt. The end of the cover loading conveyor belt is connected to the cover conveying turntable d4.

[0067] Furthermore, since the rubber stoppers are small parts, the rubber stopper feeding device C includes a rubber stopper vibratory feeder, through which the rubber stoppers are conveyed. The output end of the rubber stopper vibratory feeder is connected to the rubber stopper conveying turntable d6. The collar conveying turntable d5 is connected to the collar conveyor belt.

[0068] It should be noted that in this embodiment, the cover conveying turntable d4, the first turret material handling assembly e53e43d23, and the collar conveying turntable d5 are arranged side by side; the rubber stopper conveying turntable d6, the second turret material suction assembly e53d20, and the discharge conveying turntable d7 are arranged side by side; and the intermediate turntable d3 occupies a separate column. This maximizes space utilization, and the operation of each mechanism will not interfere with each other.

[0069] This embodiment utilizes the continuous rotation characteristics of the first turret suction assembly e53d2 and the second turret suction assembly e53d20 to simultaneously perform suction, placement, and assembly actions at multiple workstations, achieving parallel operation at multiple workstations. The intermediate turntable d3 acts as a buffer and transition, effectively connecting the assembly of the cover and collar in the first process and the assembly of the rubber stopper in the second process. This allows the two main assembly steps to operate independently, continuously, and efficiently, avoiding mutual waiting and significantly improving overall cycle time and production efficiency. Furthermore, the various feeding mechanisms and the discharge conveyor turntable d7 ensure continuous feeding and discharging, enabling uninterrupted production.

[0070] This embodiment centers on the first turret material handling component e53e43d23 and the second turret material suction component e53d20, with various feeding, transfer, and discharging mechanisms arranged around them, resulting in a compact and streamlined overall equipment layout. The first turret material handling component e53e43d23 is responsible for the first half, namely the assembly between the cover and the collar, while the second turret material suction component e53d20 is responsible for the second half, namely the assembly between the semi-finished product and the rubber stopper. The centrally located transfer plate coordinates the overall design, ensuring clear logic and efficient material flow.

[0071] In this embodiment, the first turret suction assembly e53d2 and the second turret suction assembly e53d20 have the same structure, both including: a rotating shaft d21, a valve control assembly d22, and a material handling assembly e53e43d23; the rotating shaft d21 is rotatably mounted on the frame d1; the valve control assembly d22 includes an air inlet cover d221 fixed to the frame d1, an air guide plate d222 fixed to the outer periphery of the rotating shaft d21 and abutting against the air inlet cover d221, and multiple air guide pipes d2 disposed on the air guide plate d222 and surrounding the rotating shaft d21. 23; The material handling assembly e53e43d23 includes a turntable d231 and multiple suction pipes d232 mounted on the turntable d231. Each suction pipe d232 is connected to a corresponding air guide pipe d223. The air inlet cover d221 is provided with an air inlet nozzle d2211 and an air vent d2212 connected to the air inlet nozzle d2211. When the rotating shaft d21 rotates, it drives the air guide plate d222 and the air guide pipes d223 to rotate relative to the air inlet cover d221, so that each air guide pipe d223 passes through the air vent d2212 in sequence.

[0072] The rotating air guide plate d222 and air guide tube d223 assembly move relative to the fixed air inlet cover d221, switching the airflow on and off through the air passage groove d2212 on the physical contact surface. Only the air guide tube d223 currently aligned with the air passage groove d2212 is connected to the vacuum source; air guide tubes d223 in other positions are effectively blocked by the air guide plate d222, remaining in a disconnected airflow state. Thus, there is no need to equip each suction tube d232 with a separate solenoid valve. The suction and release actions of the suction tube d232 are automatically determined by whether it passes through the air passage groove d2212 during rotation, resulting in more precise suction and release actions and a simpler structure.

[0073] Specifically, for the valve control assembly d22, when the shaft d21 rotates, the intake cover d221 is fixed on the frame d1 and does not rotate synchronously with the shaft d21; the air guide plate d222 rotates synchronously with the shaft d21, and when the air guide plate d222 rotates, it will synchronously drive multiple air guide pipes d223 to rotate, so that each air guide pipe d223 passes through the ventilation groove d2212 in sequence, and the air guide pipe d223 will be blocked by the intake cover d221 if it does not pass through the ventilation groove d2212. For the material handling assembly e53e43d23, the turntable d231 rotates synchronously with the rotating shaft d21, that is, the turntable d231 and the air guide plate d222 rotate synchronously. The number of suction pipes d232 on the turntable d231 is the same as the number of air guide pipes d223, and they are connected one-to-one. Therefore, when the air guide pipe d223 passes through the air passage d2212, the suction pipe d232 can connect with the air source to achieve its adsorption function. The air guide pipe d223 and the suction pipe d232 can be connected by a flexible hose (not shown in the figure).

[0074] In this embodiment, an upper guide cam d24 is also fixed on the frame d1. The outer periphery of the upper guide cam d24 is provided with an upper cam groove d241. The suction pipe d232 is movably engaged in the upper cam groove d241 through an upper guide wheel. The upper guide cam d24 is located at one end of the suction pipe d232 and can slide and rotate along the upper cam groove d241.

[0075] When the rotating shaft d21 drives the suction assembly e53 to rotate, the upper guide wheel fixed on the suction pipe d232 is forced to move along the trajectory of the upper cam groove d241. The change in the depth of the groove forces the guide wheel to produce precise upward or downward movements in the vertical direction to facilitate material suction. This eliminates the need for a separate cylinder or electric cylinder at each suction pipe d232 position for lifting, simplifying the structure and reducing costs. The rising, falling, holding height, and movement speed of the suction pipe d232 are entirely mechanically programmed and enforced by the geometry of the cam groove, eliminating the need for an independent lifting actuator for each suction pipe d232. This represents another significant simplification in mechanical motion control following the "no independent air valve" design.

[0076] The first turret material handling component e53e43d23 or the second turret suction component e53d20 in this embodiment also includes a feeding turntable d25. The feeding turntable d25 can act as a transfer buffer. Taking the first turret material handling component e53e43d23 as an example, the feeding turntable d25 first receives the collar from the collar conveying turntable d5, drives the collar to move and approach the cover conveying turntable d4. When it moves to the suction station, the suction pipe d232 sucks up the cover and then presses the cover into the collar at the next station.

[0077] In this embodiment, the air guide plate d222 abuts against the air intake cover plate d221 via a pressing assembly d26. The pressing assembly d26 includes a support base d261 fixed to the turntable d231 and sleeved around the outer periphery of the rotating shaft d21, multiple guide rods d262 disposed on the support base d261 and surrounding the rotating shaft d21, and multiple first elastic elements d263 respectively sleeved on the corresponding guide rods d262. The support base d261 is a sleeve-shaped mechanism that does not contact the rotating shaft d21 but rotates synchronously with the turntable d231. One end of the support base d261 is fixedly connected to the turntable d231, and the other end is provided with a radially outwardly extending flange, with guide rods evenly spaced on the flange. The guide rod d262 can abut against or partially insert into the air guide plate d222 to position the air guide plate d222 and prevent it from shifting. Meanwhile, the first elastic element d263 is a metal spring, which is sleeved on the outer periphery of the guide rod and presses the air guide plate d222 against the pressure plate.

[0078] The air guide plate d222 and the air intake cover d221 are relatively rotating friction sealing surfaces. Long-term operation inevitably leads to uniform wear on the contact surfaces. The clamping assembly d26 continuously and automatically provides a constant clamping force to compensate for minor gaps caused by wear, maintaining the necessary sealing pressure between the air guide plate d222 and the pressure plate to prevent vacuum leakage. The guide rods are evenly arranged around the rotating shaft d21, ensuring that the clamping force applied to the air guide plate d222 is highly uniformly distributed throughout the circumference. This uniformly distributed clamping force effectively prevents problems such as local deformation, warping, or tilting of the air guide plate d222 due to uneven force. The air intake cover d221 can be a split structure, such as including a cover body and a pressure plate, which are detachably connected. The pressure plate abuts against the air guide plate d222, facilitating maintenance and replacement of the pressure plate.

[0079] In this embodiment, a lower guide cam d27 is also fixedly provided on the frame d1. The lower guide cam d27 has a lower cam groove d271 on its outer periphery. Multiple support rods d28 corresponding to multiple suction pipes d232 are movably locked on the limiting ring. One end of the support rod d28 is opposite to the suction pipe d232, and the other end is movably locked in the lower cam groove d271 through the lower guide wheel.

[0080] As the rotating shaft d21 drives the entire suction mechanism to rotate, the lower guide wheel moves along the lower cam groove d271. The shape and trajectory of the lower cam groove d271 correspond to the upper cam groove d241, allowing the support rod d28 to extend and retract according to a predetermined pattern. The support rod d28 works in conjunction with the suction pipe d232. When suction is needed, the support rod d28 pushes the suction pipe d232 to make it come into close contact with the product, forming a good seal and ensuring the vacuum suction effect. When discharging, the support rod d28 retracts, separating the suction pipe d232 from the product, smoothly completing the discharging process.

[0081] Understandably, the movement of the support rod d28 is driven by the movement of the lower guide wheel, which rotates synchronously with the shaft d21, within the fixed lower cam groove d271. The contour design of the lower cam groove d271 ensures that the extension movement of the support rod d28 is strictly synchronized with the angle of the shaft d21 (i.e., the position of the intake pipe d232).

[0082] It should be noted that the cover feeding conveyor belt in this embodiment is provided with multiple limiting protrusions, and the cover is placed between two adjacent limiting protrusions. The limiting protrusions form continuous equidistant physical compartments on the conveyor belt, and each cover is forcibly constrained within a fixed distance between adjacent protrusions. This can effectively solve the problems of the cover rolling, deflecting, or colliding with each other during the conveying process. At the same time, when the cover is moved to the end of the conveyor, the limiting protrusions can push the cover into the cover conveying turntable d4.

[0083] This embodiment also includes a rotary drive mechanism d8, which includes a first rotary drive component d81, a main gear d82 located at the output end of the first rotary drive component d81, and a plurality of driven gears d83 respectively connected to the cover conveying turntable d4, the rotating shaft d21, the collar conveying turntable d5, the intermediate turntable d3, the rubber plug conveying turntable d6, and the discharge conveying turntable d7, with adjacent driven gears d83 meshing with each other.

[0084] All turntables are rigidly connected by meshing gears, ensuring that the start and stop angles and rotation speeds of each station are completely synchronized, eliminating the cumulative errors caused by independent drives. The gear system driven by the main gear d82 has a fixed transmission ratio, and the relative positional relationship between the turntables is constant, ensuring that the material is always at a preset angle at the junction point, which can improve the repeatability and positioning accuracy of gripping and placing.

[0085] In this embodiment, a visual inspection mechanism and a defective product recycling mechanism are sequentially arranged in the conveying direction of the cover feeding mechanism, the collar feeding mechanism, the rubber stopper feeding mechanism, and the discharge conveyor turntable d7. The visual inspection mechanism is a commonly used inspection device, including a bracket and a visual camera. The visual camera d1 is mounted on the product conveying path via the bracket to inspect the product and send the inspection results to the defective product recycling mechanism through the system. The defective product recycling mechanism includes a storage unit and a removal unit. The removal unit can use a robotic arm to grab or blow air to transfer defective products into the storage unit. It is an existing conventional device, and its specific structure will not be described in detail here.

[0086] Incoming material defects, such as scratches, deformation, stains, and dimensional deviations, are detected at the feeding inlets of the cover, collar, and rubber stopper. This intercepts defective products at the source, preventing ineffective processing. The D77 discharge conveyor turntable performs full inspection of finished products, preventing defective products from flowing downstream.

[0087] The working principle of the cover plate assembly device D in this embodiment is as follows: the cover, collar, and rubber stopper are sequentially conveyed to the cover conveying turntable d4, collar conveying turntable d5, and rubber stopper conveying turntable d6. The cover conveying turntable d4, collar conveying turntable d5, intermediate turntable d3, rubber stopper conveying turntable d6, discharge conveying turntable d7, first turret material handling component e53e43d23, and second turret material suction component e53d20 rotate synchronously. During the rotation, the collar conveying turntable d5 conveys the collar to the first turret material handling component e53d20. In the first turret material handling assembly e53e43d23, the feeding turntable d25 drives the collar to rotate to the docking point with the cover conveying turntable d4. This docking point is set as the suction station. At this time, the suction pipe d232 in the first turret material handling assembly e53e43d23 will descend and pick up the cover located at the suction station. Then, at the next station of the suction station, the cover is pressed into the collar located on the feeding turntable d25. At this time, the semi-finished assembly of the cover and the collar is completed.

[0088] Secondly, the semi-finished product flows from the feeding turntable d25 in the first turret material handling assembly e53e43d23 into the intermediate turntable d3 for buffering. The semi-finished product in the intermediate turntable d3 continues to be transferred and enters the feeding turntable d25 in the second turret suction assembly e53d20. At this time, the suction pipe d232 in the second turret suction assembly e53d20 will pick up the rubber stopper located on the rubber stopper conveying turntable d6. Then, at the assembly station in the feeding turntable d25 of the second turret suction assembly e53d25, the rubber stopper is pressed onto the semi-finished product, thereby completing the assembly of the cover plate. After the cover plate is assembled, it will be transferred from the feeding turntable d25 of the second turret suction assembly e53d25 to the discharge conveying turntable d7 to complete the discharge.

[0089] In this embodiment, the finished product inspection device E includes: an incoming conveyor belt e1, a surface inspection mechanism e2, a side inspection mechanism e3, a patent mechanism, a defective product classification mechanism e5, and an outgoing conveyor belt e6b4; the surface inspection mechanism e2 is connected to the incoming conveyor belt e1 and is used to inspect the surface of the finished product; the side inspection mechanism e3 is arranged adjacent to the surface inspection mechanism e2 and is used to inspect the circumferential side of the finished product; the transfer mechanism e4 includes a transfer bracket e41, a rotary drive assembly e42 mounted on the transfer bracket e41, and a plurality of picking components e53e43d23 connected to the output end of the rotary drive assembly e42; the rotary drive assembly e42 is used to drive the picking components e53e43d23 to perform circumferential motion around an axis; the defective product classification mechanism e5 is arranged adjacent to the transfer mechanism e4 and is used to receive, classify, and store defective products; wherein, the surface inspection mechanism e2, the side inspection mechanism e3, the defective product classification mechanism e5, and the outgoing conveyor belt e6b4 are arranged sequentially along the circumferential motion path of the picking components e53e43d23.

[0090] By setting up surface inspection mechanism e2 and side inspection mechanism e3, the surface and circumferential sides of the assembled cylindrical battery cover are inspected respectively, enabling comprehensive quality inspection of the finished product. This effectively avoids defects missed due to a single inspection angle and improves the overall quality stability of the product. The transfer mechanism e4 adopts a rotary design and is equipped with multiple material handling components e53e43d23. During rotation, it sequentially passes through multiple stations, including surface inspection, side inspection, defective product rejection and sorting, and good product unloading. Thus, while one battery cover is undergoing surface inspection, another may be undergoing side inspection or being transferred, achieving parallel processing of the inspection process. This greatly increases equipment throughput, reduces waiting time in intermediate stages, significantly improves inspection efficiency, and lowers production costs.

[0091] The rotary drive assembly e42 in this embodiment includes a motor mounted on a transfer bracket e41 and a rotary bracket connected to the output shaft of the motor. The rotary bracket has multiple extension arms, and multiple material handling assemblies e53e43d23 are respectively disposed on the corresponding extension arms. The material handling assembly e53e43d23 includes a cylinder and a vacuum nozzle fixed to the output end of the cylinder. The vacuum nozzle can achieve suction and release actions through the control of a solenoid valve.

[0092] The surface inspection mechanism e2 in this embodiment includes a finished product conveying turntable e21 and a plurality of first vision inspection modules e22 arranged at intervals along the outer periphery of the finished product conveying turntable e21; the side inspection mechanism e3 includes an inspection bracket e31 and a plurality of second vision inspection modules e32, the inspection bracket e31 is provided with an inspection station, and the plurality of second vision inspection modules e32 are arranged at intervals around the inspection station.

[0093] The first vision inspection module e22 includes a fixed frame positioned next to the finished product conveyor turntable e21, and a camera and supplementary lighting arranged sequentially from top to bottom on the fixed frame, with both the camera and supplementary lighting located above the conveying path of the finished product. Furthermore, multiple vision modules can be configured with different light sources and lens angles to optimize imaging effects for different surface features. Supplementary lighting is provided at the inspection station. The transfer bracket e41 picks up the finished product from the finished product conveyor turntable e21 and places it at the inspection station, where multiple second vision inspection modules e32 capture side images of the finished product for side inspection.

[0094] The arrangement of multiple first-vision inspection modules e22 ensures that the entire surface of each battery cover is captured multiple times by cameras at different positions and angles as it rotates through the inspection area, effectively eliminating blind spots from a single perspective. Multiple second-vision inspection modules e32 are spaced around the inspection station, forming a multi-angle, all-around vision inspection ring. The entire circumference of the battery cover can be captured by all the surrounding second-vision inspection modules e32.

[0095] It should be noted that the second vision inspection module e32 includes a guide plate e321, a movable base e322, and an inspection camera e323. The guide plate e321 is mounted on the inspection bracket e31, the movable base e322 is slidably mounted on the guide plate e321, and the inspection camera e323 is rotatably mounted on the movable base e322. The movable base e322 can be locked to the guide plate e321 by bolts or other structures to ensure stability during use. The inspection camera e323 can swing relative to the movable base e322 to adjust its shooting angle.

[0096] The sliding of the movable seat e322 along the guide plate e321 allows the position of the inspection camera e323 to be adjusted in the direction close to or far from the center of the inspection station. This precisely controls the working distance between the inspection camera e323 and the side of the battery cover, so as to obtain the most suitable field of view to cover the side area to be inspected, while achieving the best image resolution to identify minute defects.

[0097] It should be noted that this embodiment also includes a pressure-holding mechanism e7, which is connected to both the discharge conveyor turntable d7 and the incoming conveyor belt e1, for pressure holding and airtightness checks of the finished cover plate. This is existing conventional equipment, and its specific structure will not be described in detail here.

[0098] In this embodiment, the defective product sorting mechanism e5 includes two symmetrically arranged storage mechanisms and a material distribution mechanism r51 located between the two storage mechanisms; the storage mechanism includes a conveying component e53e52, a pushing component e53, and a storage component e54, with the pushing component e53 and the storage component e54 respectively arranged on both sides of the conveying component e53e52 in the conveying direction; the pushing component e53 is located at the output end of the conveying component e53e52 and is used to push materials from the conveying component e53e52. 53e52 is pushed to the storage component e54; the distributing mechanism r51 includes a second rotary drive e511 and a distributing disk e512. The distributing disk e512 is connected to the output end of the second rotary drive e511 and has two discharge ends e5121. The second rotary drive e511 is used to drive the distributing disk e512 to rotate and swing, so that one of the two discharge ends e5121 can be selectively connected to the input end of the corresponding conveying component e53e52 in the two sets of storage mechanisms. The second rotary drive e511 is a rotary cylinder or a stepper motor, which can achieve alternating forward and reverse rotation.

[0099] The symmetrically arranged two sets of storage mechanisms can simultaneously receive and process defective products from the transfer mechanism e4, achieving parallel operation through dual channels. Repairable and non-repairable defective products are separated, eliminating the need for manual screening and significantly improving sorting efficiency. Specifically, the distribution disc e5125 has two discharge ends e5121, controlled by a second rotary drive e511, dynamically switching between them. By receiving upstream detection information, it can intelligently and dynamically allocate defective product categories to the two storage mechanisms in real time. One storage mechanism is dedicated to temporarily storing repairable defective products, while the other stores non-repairable products, enabling further screening of defective products and achieving continuous, uninterrupted sorting.

[0100] The conveying assembly e53e52 is equipped with a conveying channel e521. The beginning of the conveying channel e521 has a gradually tapering opening e522, and the end of the conveying channel e521 has a discharge notch e523. The pushing assembly e53 and the storage assembly e54 are respectively connected to the two ends of the discharge notch e523. The gradually tapering opening e522 has a gradually narrowing structure, meaning the end closer to the distributing mechanism r51 is a large opening, and the end farther from the distributing mechanism r51 is a small opening. A baffle b52 is provided at the end of the conveying channel e521 to limit material movement and prevent it from leaving the conveying channel e521. The discharge notch e523 spans the conveying channel e521, and both ends can serve as outlets, allowing material to smoothly exit from the end of the discharge notch e523.

[0101] The conveyor channel e521 provides a clear path for defective products, and physical limiting prevents material from shifting or jamming during transport. The gradually changing opening e522 design guides defective products into the narrow conveyor channel e521 step by step, achieving natural centering and posture correction, reducing classification errors or equipment jams caused by material tilting. The discharge notch e523 serves as a transition node between the pushing component e53 and the storage component e54. The pushing component e53 horizontally pushes defective products from one end of the notch to the storage component e54, which receives them from the other end, forming a continuous action.

[0102] The material conveying assembly e53e52 of this embodiment includes a mounting base, a material conveying drive and a conveyor belt disposed on the mounting base. The material conveying drive is used to drive the conveyor belt to transport materials. The conveying channel e521 is located on the mounting base, and the conveyor belt is located within the conveying channel e521. The conveying channel e521 is formed on the mounting base, and the conveying surface of the conveyor belt is located within the conveying channel e521.

[0103] The feeding assembly e53 in this embodiment includes a feeding drive component e531 and a push plate e532 connected to the output end of the feeding drive component e531. The push plate e532 can slide within the discharge notch e523. The feeding drive component e531 can be a linear drive structure such as a cylinder, an electric push rod, or a screw drive mechanism. The feeding drive component e531 is fixed on the mounting base, and the push plate e532 is parallel to the conveyor belt and can horizontally push the material.

[0104] In this embodiment, the material storage component e54 is mounted on one side of the material conveying component e53e52 via a positioning seat e55. The material storage component e54 includes a limiting block e541, a lifting drive component e542, and an elastic limiting block e543. The limiting block e541 is provided with a feeding groove e5411 opposite to the discharge notch e523. The output end of the lifting drive component e542 extends into the feeding groove e5411. The elastic limiting block e543 is located on the inner sidewall of the feeding groove e5411. The lifting drive component e542 is used to lift the material and lock it onto the elastic limiting block e543. Specifically, the limiting block e541 has a "U" shaped structure, and its hollow interior is the feeding groove e5411, with its opening facing the discharge notch e523. The push plate e532 can push defective products from the conveyor belt along the discharge notch e523 into the feed trough e5411. Then the lifting drive e542 lifts the defective products and supports them through the elastic limit block e543. That is, there is always a space for movement in the feed trough e5411 to facilitate the pushing and lifting of defective products.

[0105] The material storage assembly e54, via the lifting drive e542, vertically lifts defective products from the feed chute e5411 to the height of the elastic limiting block e543. The defective product compresses the elastic limiting block e543, causing it to contract until the defective product is positioned above it. At this point, the elastic limiting block e543 supports the defective product, forming a two-stage positioning mechanism with vertical support and horizontal limiting. There are at least two elastic positioning blocks, providing two-point support for the material to ensure stability.

[0106] The inner wall of the limiting block e541 is provided with a mounting hole e5412. An elastic limiting block e543 is movably installed within the mounting hole e5412 and partially extends into the feed chute e5411. A second elastic element (not shown in the figure) is provided within the mounting hole e5412 and connected to the elastic limiting block e543, allowing the elastic limiting block e543 to retract completely into the mounting hole e5412. The second elastic element can be a metal spring or a bellows spring.

[0107] The elastic limiting block e543 is connected to the mounting hole e5412 via a second elastic element, and the portion extending out of the feed chute e5411 is designed with a wedge-shaped or arc-shaped contact surface. The elastic limiting block e543 is used to support defective products; when the lifting drive e542 lifts the defective product, the elastic limiting block e543 automatically retracts into the mounting hole e5412 under the radial pressure of the defective product. At the same time, the second elastic element generates a reverse elastic force, which rebounds to support the defective product when the material leaves contact with the elastic limiting block e541.

[0108] It should be noted that the limiting block e541 is provided with multiple limiting rods e56, which are arranged at intervals around the feed chute e5411. This embodiment takes four limiting rods e56 as an example. The four limiting rods e56 are arranged in a matrix, and the distance between two adjacent limiting rods e56 is smaller than the diameter of the material. This can effectively prevent the material from coming out of the gap between the limiting rods e56.

[0109] In this embodiment, at least two storage components e54 are spaced apart on the positioning seat e55. These at least two storage components e54 are spaced apart along the conveying direction of the conveying component, and the positioning seat e55 is movable. The positioning seat e55 can move bidirectionally, driving the movement of the storage components e54 so that different storage components e54 can dock with the discharge notch e523 on the conveying component. Thus, when one storage component e54 is full, the positioning seat e55 can be quickly moved so that another empty storage component e54 docks with the discharge notch e523 to continue storing material, enabling non-stop operation and further improving product production efficiency.

[0110] In this embodiment, the dual-disc switching mechanism f1 includes a material rack f11, a first material tray f12 and a second material tray f13 disposed on the material rack f11, and a switching drive assembly f14. The material rack f11 is provided with a first guide rail f111 and a second guide rail f112 located below the first guide rail f111. The first material tray f12 and the second material tray f13 are slidably disposed on the first guide rail f111 and the second guide rail f112, respectively. The switching drive assembly f14 can synchronously drive the first material tray f12 and the second material tray f13 to move in opposite directions on the first guide rail f111 and the second guide rail f112, respectively.

[0111] By switching drive component f14 to synchronously drive the two material trays to move in opposite directions along the upper and lower guide rails, rapid switching between two workstations can be achieved. When the first material tray f12 is in the processing position, the second material tray f13 can simultaneously perform unloading operations, which can significantly reduce equipment waiting time and improve production cycle time.

[0112] In this embodiment, a slide plate f15 is slidably mounted on the second guide rail f112, and a slide rod f131 and a push rod f132 are mounted on the second material tray f13. Multiple slide rods f131 are movably inserted into the slide plate f15, allowing the second material tray f13 to rise and fall relative to the slide plate f15. A limiting plate f16 is also provided on the material rack f11, with a guide groove f161 on the limiting plate f16. One end of the push rod f132 is connected to the second material tray f13, and the other end is movably engaged within the guide groove f161. When the slide plate slides along the second guide rail f112, the push rod f132 simultaneously slides along the guide groove f161, simultaneously driving the second material tray f13 to rise and fall relative to the slide plate f15. The guide trough f161 includes a horizontal trough and an inclined trough connected to both ends of the horizontal trough. The horizontal trough is located at the lowest point. When the push rod f132 moves to the horizontal trough, the second material tray f13 is in a descending state; when the push rod f132 moves to the inclined trough, the second material tray f13 is in a rising state.

[0113] The switching drive assembly f14 in this embodiment includes a linear motor f141, a transmission belt f143, and multiple pulleys f142 mounted on a material rack f11. The multiple pulleys f142 are rotatably mounted, and the transmission belt f143 is fitted onto the multiple pulleys f142. The first material tray f12 is connected to the output end of the linear motor f141 via a slider f121, and the first material tray f12 is also connected to the transmission belt f143 via a first clamping block f122. The second material tray f13 is connected to the transmission belt f143 via a second clamping block f133. The first clamping block f122 and the second clamping block f133 are respectively clamped at different positions on the belt.

[0114] The operating principle of the dual-disc switching mechanism f1 in this embodiment is as follows: When the linear motor f141 is running, the slider f121 drives the first disk f12 to move along the first guide rail f111. At this time, since the first clamping block f122 on the first disk f12 clamps the transmission belt f143, it will drive the transmission belt f143 to move synchronously, thereby driving the second clamping block f133 and the second disk f13 to move along the second guide rail f112. When the second disk f13 moves, it will drive the slide plate f15 to move synchronously. Since the top rod f132 on the second disk f13 will slide in the guide groove f161, the second disk f13 will rise and fall during the movement. In this way, the first disk f12 and the second disk f13 can be misaligned vertically during movement to avoid motion interference. After the position is switched, they can still be on the same plane, which improves the convenience of use.
