Abstract
Description
Technical Field
[0001] This invention relates to the field of testing equipment technology, and in particular to a fully automated electrochemical testing system. Background Technology
[0002] Electrochemical detection technology, as a high-precision and widely used analytical method, has significant advantages and promising prospects in the field of material detection, and is widely used in many important areas such as batteries, sensors, and corrosion monitoring. However, traditional electrochemical testing methods usually rely on manual operation, including complex pretreatment steps such as reagent preparation, sample processing, electrode assembly, and cleaning. These processes are not only cumbersome and time-consuming, but also result in high labor costs and low overall testing efficiency.
[0003] In addition, manual intervention can easily introduce operational errors, such as electrode contamination, bubble interference, or potential drift, which directly affect the accuracy and repeatability of test results.
[0004] Therefore, there is an urgent need to provide a fully automated electrochemical testing system to address the problems existing in the current technology to some extent. Summary of the Invention
[0005] The purpose of this invention is to provide a fully automated electrochemical testing system, which can, to some extent, solve the problem that the current electrochemical testing process still requires manual intervention, resulting in low testing efficiency and inaccurate test results.
[0006] This invention provides a fully automated electrochemical testing system, comprising a mounting frame and a robotic arm, a quick-change module, a storage mechanism, a storage rack, a first tray, a second tray, a third tray, a capping mechanism, a recycling box, a cleaning mechanism, and a mobile assembly device integrated on the mounting frame. The storage mechanism carries a working part adapted to the robotic arm, and the working part is detachably connected to the robotic arm. The quick-change module can fix the working part, allowing the robotic arm to separate from the working part. The storage rack holds the lower tooling; the first tray holds the sample, the second tray holds the pipette tip, and the third tray holds the reagent bottle, electrode assembly, and test cup. The capping mechanism can clamp the reagent bottle and open it. The recycling box is used to collect discarded pipette tips, and the cleaning mechanism is used to clean the test cup. The mobile assembly device is used to assemble the sample, the test cup, and the electrode assembly.
[0007] The mobile assembly device includes a mounting frame, a moving mechanism, and a pressing mechanism. The moving mechanism includes a first slide rail, a first slider, a first drive, and a mounting base. The first slide rail is laid on the mounting frame, the first slider is slidably disposed on the first slide rail, the first drive can drive the first slider to reciprocate on the first slide rail, and the mounting base is connected to the first slider and is used to support the lower tooling. The pressing mechanism is connected to the mounting frame and is located at a first position in the extension direction of the first slide rail. The pressing part of the pressing mechanism can move towards or away from the mounting base.
[0008] Specifically, the mobile assembly device further includes a liquid injection mechanism, which is connected to the mounting bracket and located at a second position in the extension direction of the first slide rail.
[0009] Specifically, the pressing mechanism includes a second drive and a pressure plate. The second drive is connected to the mounting bracket, and the telescopic end of the second drive is connected to the pressure plate.
[0010] The lower tooling includes a housing, an insert plate, a spring, and a pusher. The housing forms a first receiving cavity and a second receiving cavity. The spring is disposed in the first receiving cavity, with one end abutting against the bottom of the first receiving cavity and the other end connected to one end of the pusher. The other end of the pusher can enter the second receiving cavity. The insert plate is slidably connected to the housing along the radial direction of the housing, and one end of the insert plate can enter or disengage from the second receiving cavity. The test cup can enter the second receiving cavity, and the test cup has a slot formed at the position corresponding to the insert plate.
[0011] Specifically, a positioning groove is formed at the end of the test cup, and a positioning protrusion is formed at the end of the electrode assembly corresponding to the position of the positioning groove. The positioning protrusion can be inserted into the positioning groove so that the electrode assembly is connected to the test cup.
[0012] Furthermore, the electrode assembly includes a reference electrode, a foil electrode, and a housing. The positioning protrusion is formed at the end of the housing. Both the reference electrode and the foil electrode are disposed within the housing, and one end of the reference electrode and the foil electrode extends out of the housing.
[0013] The mounting frame includes a first mounting plate and a second mounting plate, which are arranged in parallel, with the second mounting plate being at a higher horizontal height than the first mounting plate. A first slide rail is mounted on the first mounting plate, and the pressing mechanism and the liquid injection mechanism are both suspended on the side of the second mounting plate facing the first mounting plate. A second slide rail is laid on the second mounting plate, and a second slider is slidably mounted on the second slide rail. A support seat is provided on the second slider, and an isolation cover is also provided on the second mounting plate. The second slider can drive the support seat to enter or leave the isolation cover.
[0014] Specifically, the isolation cover includes a cover body and a door body, the door body is slidably connected to the cover body, and the door body can rise or fall in the vertical direction to open or close the cover body, allowing the support seat to enter or leave the cover body.
[0015] Furthermore, the storage rack and the mobile assembly device are disposed opposite each other at both ends of the mounting frame in the length direction, and a third slide rail is provided on the mounting frame located between the storage rack and the mobile assembly device, and the positioning end of the robotic arm is slidably disposed on the third slide rail.
[0016] Compared with existing technologies, the fully automated electrochemical testing system provided by this invention has the following advantages:
[0017] The fully automated electrochemical testing system provided by this invention includes an installation frame and a robotic arm, a quick-change module, a storage mechanism, a storage rack, a first tray, a second tray, a third tray, a capping mechanism, a recycling box, a cleaning mechanism, and a mobile assembly device integrated on the installation frame. The storage mechanism carries a working part adapted to the robotic arm, and the working part is detachably connected to the robotic arm. The quick-change module can fix the working part to separate the robotic arm from the working part. The storage rack is used to hold the lower tooling. The first tray is used to hold the sample, the second tray is used to hold the pipette tip, and the third tray is used to hold the reagent bottle, electrode assembly, and test cup. The capping mechanism can hold the reagent bottle and open the cap. The recycling box is used to collect the discarded pipette tip, and the cleaning mechanism is used to clean the test cup. The mobile assembly device is used to assemble the sample, test cup, and electrode assembly.
[0018] Analysis shows that by integrating the robotic arm, quick-change module, storage mechanism, storage rack, first tray, second tray, third tray, capping mechanism, recycling box, cleaning mechanism, and mobile assembly device onto the mounting frame, the overall system integration can be improved, thereby greatly reducing the equipment's footprint. Furthermore, since the entire operation process of the testing system provided in this application requires the use of a robotic arm for grasping and transferring, the range of motion of the robotic arm can be satisfied, thus achieving a fully automated operation.
[0019] The integrated storage mechanism and quick-change module enable the disassembly and installation of the front-end working part of the robotic arm. Since the storage mechanism provided in this application stores a variety of working parts, such as grippers, it is not necessary to design multiple robotic arms. Multiple operations can be performed simply by changing the working parts.
[0020] The robotic arm and quick-change module in this application are existing commonly used robotic arms and replacement structures, and will not be described in detail here.
[0021] Accordingly, the storage rack integrated into the mounting frame enables the integration of the lower tooling. Furthermore, the storage rack in this application comprises two layers: the upper layer can support the lower tooling with the electrode assembly and test cup assembled, allowing for sufficient testing time; while the lower layer supports the lower tooling, awaiting gripping and transfer by the robotic arm.
[0022] The first, second, and third trays can hold samples, pipette tips, reagent bottles, electrode assemblies, and test cups, making it easier for the robotic arm to grasp them and complete automated operations.
[0023] It is understandable that, since the reagent bottle contains a slow-release agent, and the slow-release agent needs to be dripped into the test cup during the electrochemical test, this application can open the reagent bottle by integrating a screw-on mechanism on the mounting frame. The screw-on mechanism provided by this application includes at least a clamping seat, and the clamping seat can include a positioning block fixed on the mounting frame and a movable block that can move toward or away from the positioning block. The movable block can be driven by a telescopic structure such as a cylinder. When the robotic arm grabs the reagent bottle and transfers it to the screw-on mechanism, the movable block moves away from the positioning block, allowing the reagent bottle to enter the clamping space. After it is in position, the movable block moves toward the positioning block until it clamps the reagent bottle.
[0024] The subsequent opening process involves the robotic arm gripping the reagent bottle cap and rotating the gripper to open the cap.
[0025] Once the reagent bottle is opened, the robotic arm grips the suction tip and inserts it into the bottle to adsorb the slow-release agent. After adsorption is complete, the suction tip is inserted into the test cup to inject the slow-release agent. Finally, the reagent bottle is placed into the recycling box to prevent contamination of the work environment.
[0026] In actual operation, before adding the slow-release agent to the test cup, the robotic arm first clamps the lower fixture into the moving assembly device for positioning. Then, the sample and test cup are sequentially loaded into the lower fixture. After assembly, the moving assembly device injects saline solution into the test cup, completing the above-mentioned slow-release agent addition operation. Finally, the robotic arm picks up the electrode assembly and installs it onto the test cup, thus completing the assembly of the overall electrochemical assembly.
[0027] After the test is completed, the test cup can be put into the cleaning mechanism for cleaning, thereby realizing the recycling of the test cup.
[0028] Therefore, the fully automated electrochemical system provided in this application achieves unmanned operation throughout the entire process from grasping, assembly, liquid injection, assembly, testing, and cleaning, fundamentally eliminating fluctuations in test results caused by human factors and significantly improving data consistency and repeatability. Simultaneously, the automated process can operate 24 hours a day without interruption, and the test throughput is increased by orders of magnitude compared to manual operation.

[0045] like Figures 1-5As shown, the present invention provides a fully automated electrochemical testing system, including a mounting frame 1 and a robotic arm 2, a quick-change module, a storage mechanism 3, a storage rack 4, a first tray 5, a second tray 6, a third tray 7, a capping mechanism 13, a recycling box 14, a cleaning mechanism 15, and a moving assembly device integrated on the mounting frame 1. The storage mechanism 3 is used to carry the working part adapted to the robotic arm 2, and the working part is detachably connected to the robotic arm 2. The quick-change module can fix the working part so that the robotic arm 2 can be separated from the working part. The storage rack 4 is used to hold the lower tooling 17, the first tray 5 is used to hold the sample 8, the second tray 6 is used to hold the pipette tip 9, and the third tray 7 is used to hold the reagent bottle 11, the electrode assembly 12, and the test cup 10. The capping mechanism 13 can clamp the reagent bottle 11 and open the reagent bottle 11. The recycling box 14 is used to collect the discarded pipette tip 9, and the cleaning mechanism 15 is used to clean the test cup 10. The moving assembly device is used to assemble the sample 8, the test cup 10, and the motor assembly.
[0046] Compared with existing technologies, the fully automated electrochemical testing system provided by this invention has the following advantages:
[0047] The fully automated electrochemical testing system provided by this invention integrates the robotic arm 2, quick-change module, storage mechanism 3, storage rack 4, first tray 5, second tray 6, third tray 7, capping mechanism 13, recycling box 14, cleaning mechanism 15, and mobile assembly device onto the mounting frame 1. This improves the overall system integration and greatly reduces the equipment's footprint. Furthermore, since the entire operation process of the testing system provided by this application requires the use of the robotic arm 2 for grasping and transferring, the range of motion of the robotic arm 2 can be satisfied, thereby achieving a fully automated operation mode.
[0048] The integrated storage mechanism 3 and quick-change module enable the disassembly and installation of the front-end working part of the robotic arm 2. Since the storage mechanism 3 provided in this application stores a variety of working parts, such as grippers, it is not necessary to design multiple robotic arms 2. Multiple operations can be performed simply by changing the working parts.
[0049] The robotic arm 2 and quick-change module in this application are both existing commonly used robotic arms 2 and replacement structures, which will not be described in detail here.
[0050] Accordingly, the storage rack 4 integrated on the mounting frame 1 enables the integration of the lower tooling 17, and simultaneously, as Figure 1 As shown, the storage rack 4 in this application includes two layers. The upper layer can support the lower fixture 17 with the electrode assembly 12 and test cup 10 assembled, allowing it sufficient testing time. The lower layer supports the lower fixture 17, waiting for the robotic arm 2 to grasp and transfer it.
[0051] The first tray 5, the second tray 6, and the third tray 7 can support the sample 8, the pipette tip 9, the reagent bottle 11, the electrode assembly 12, and the test cup 10, thus facilitating the robotic arm 2 to grasp them and complete the automated operation.
[0052] It is understandable that, since the reagent bottle 11 contains a slow-release agent, and the slow-release agent needs to be dripped into the test cup 10 during the electrochemical test, this application can open the reagent bottle 11 by integrating a screw capping mechanism 13 on the mounting frame 1. The screw capping mechanism 13 provided by this application includes at least a clamping seat, and the clamping seat may include a positioning block fixed on the mounting frame 1 and a movable block that can move toward or away from the positioning block. The movable block can be driven by a telescopic structure such as a cylinder. When the robotic arm 2 grabs the reagent bottle 11 and transfers it to the screw capping mechanism 13, the movable block moves away from the positioning block, allowing the reagent bottle 11 to enter the clamping space. After it is in place, the movable block moves toward the positioning block until it clamps the reagent bottle 11.
[0053] The subsequent opening process involves the robotic arm 2 gripping the cap of the reagent bottle 11 and rotating the gripper to open the cap.
[0054] Once the reagent bottle 11 is opened, the robotic arm 2 grabs the suction head 9 and inserts it into the reagent bottle 11 to adsorb the slow-release agent. After the adsorption is complete, the suction head 9 is inserted into the test cup 10 to inject the slow-release agent. Finally, the reagent bottle 11 is placed into the recycling box 14 to prevent pollution of the working environment.
[0055] In actual operation, before adding the slow-release agent to the test cup 10, the robotic arm 2 first clamps the lower fixture 17 into the moving assembly device for positioning. Then, the sample 8 and the test cup 10 are sequentially placed into the lower fixture 17. After assembly, the moving assembly device injects saline solution into the test cup 10, thus completing the above-mentioned slow-release agent addition operation. Finally, the robotic arm 2 picks up the electrode assembly 12 and installs it onto the test cup 10, thus completing the assembly of the overall electrochemical assembly.
[0056] After the test is completed, the test cup 10 can be put into the cleaning mechanism 15 for cleaning, thereby realizing the recycling of the test cup 10.
[0057] Therefore, the fully automated electrochemical system provided in this application achieves unmanned operation throughout the entire process from grasping, assembly, liquid injection, assembly, testing, and cleaning, fundamentally eliminating fluctuations in test results caused by human factors and significantly improving data consistency and repeatability. Simultaneously, the automated process can operate 24 hours a day without interruption, and the test throughput is increased by orders of magnitude compared to manual operation.
[0058] Optionally, such as Figures 1-3As shown, the mobile assembly device includes a mounting frame 16, a moving mechanism, and a pressing mechanism 20. The moving mechanism includes a first slide rail 18, a first slider 22, a first drive, and a mounting base 19. The first slide rail 18 is laid on the mounting frame 16, and the first slider 22 is slidably disposed on the first slide rail 18. The first drive can drive the first slider 22 to reciprocate on the first slide rail 18. The mounting base 19 is connected to the first slider 22 and is used to support the lower tooling 17. The pressing mechanism 20 is connected to the mounting frame 16 and is located at a first position in the extension direction of the first slide rail 18. The pressing part of the pressing mechanism 20 can move towards or away from the mounting base 19.
[0059] In this application, the first slide rail 18 and the first slider 22 constitute a linear motion module. The first drive can be a motor and a lead screw structure to move the first slider 22, or a pneumatic slide structure such as a cylinder can be used to realize the reciprocating motion of the second slider 1606.
[0060] Correspondingly, the lower tooling 17 can be precisely positioned by fixing it to the slider via the mounting base 19. The pressing mechanism 20 is fixed on the mounting bracket 16 and located at the first position of the slide rail stroke. This separate design of "moving to position and pressing at a fixed point" decouples the precise positioning in the horizontal direction from the precise pressing function in the vertical direction, simplifies the control logic, and allows for independent force and displacement control of the pressing process, thereby improving the pressing quality.
[0061] When the first drive is activated, the first slider 22 and its mounting base 19 (which carries the lower tooling 17 and the components to be pressed, including the sample 8 and the test cup 10) move smoothly along the first slide rail 18 to directly below the pressing mechanism 20.
[0062] Upon reaching the preset first position, the first drive stops. The pressing part of the pressing mechanism 20 receives the instruction and moves downward in the vertical direction, applying the set pressure to the component on the mounting base 19 to complete the pressing operation.
[0063] After pressing is completed, the pressing section rises, and the first drive then drives the slider to return or move to the next station.
[0064] Optionally, such as Figures 1-3 As shown, the mobile assembly device in this application also includes a liquid injection mechanism 21, which is connected to the mounting bracket 16 and is located at a second position in the extension direction of the first slide rail 18.
[0065] The injection mechanism 21 in this application is also fixedly mounted on the mounting bracket 16 and located at the second position in the extension direction of the first slide rail 18. This means that the moving mechanism can carry the same lower tooling 17 sequentially through the first position (pressing) and the second position (injection). This assembly line-style workstation design realizes modular expansion of functions, allowing multiple operation processes to be performed on a single moving platform, thereby greatly improving equipment utilization and operational efficiency.
[0066] After assembly is completed at the press-fit station, the first drive restarts, precisely moving the mounting base 19 to the second position, below the injection mechanism 21. The injection mechanism 21 in this application may include an injection pump and an injection needle. The injection pump pumps reagents to the injection needle, and the needle tip descends to align with the injection port of the test cup 10, precisely pumping in a preset volume of saline solution. After completion, the needle tip lifts, the first drive restarts, and reverses to drive the first slider 22 back to its assembly position on the first slide rail 18.
[0067] It is understood that the pressing mechanism 20 in this application includes a second drive and a pressing plate 2001. The second drive is connected to the mounting bracket 16, and the telescopic end of the second drive is connected to the pressing plate 2001.
[0068] The pressing mechanism 20 in this application includes a second drive, which can be a high-precision electric cylinder, pneumatic cylinder, or hydraulic cylinder, thereby directly driving the pressure plate 2001. The second drive is fixed on the second mounting plate 1602 of the mounting bracket 16, and its telescopic end is connected to the center of the pressure plate 2001. It has a simple structure, good rigidity, fast response, short force transmission path, and no errors or delays caused by intermediate links, which is conducive to achieving high-precision pressure control.
[0069] In actual operation, the telescopic end of the second drive drives the pressure plate 2001 to move downward. After the pressure plate 2001 contacts the workpiece, the system continues to press down to complete the pressing between the test cup 10 and the sample 8.
[0070] Optionally, such as Figure 4 Combination Figure 5 As shown, the lower tooling 17 in this application includes a housing 1701, an insert plate 1702, a spring 1703, and a pusher 1704. The housing 1701 forms a first receiving cavity and a second receiving cavity. The spring 1703 is disposed in the first receiving cavity, with one end abutting against the bottom of the first receiving cavity and the other end connected to one end of the pusher 1704. The other end of the pusher 1704 can enter the second receiving cavity. The insert plate 1702 is slidably connected to the housing 1701 along the radial direction of the housing 1701, and one end of the insert plate 1702 can enter or leave the second receiving cavity. The test cup 10 can enter the second receiving cavity, and the test cup 10 has a slot 1002 formed at the position corresponding to the insert plate 1702.
[0071] The first receiving cavity formed by the housing 1701 can accommodate the spring 1703, and the pusher 1704 further enables the transmission of the restoring force of the spring 1703. When the sample 8 and the test cup 10 are placed into the second receiving cavity in sequence, the test cup 10 will press down on the sample 8 to abut against the pusher 1704. In this application, the pusher 1704 is further provided with a working electrode and a sealing gasket, thereby ensuring the sealing effect and electrical connection of the overall structure.
[0072] Understandably, as the test cup 10 is continuously pressed down, the slot 1002 on the test cup 10 will gradually approach the insert plate 1702. When the insert plate 1702 is aligned with the slot 1002, pushing the insert plate 1702 will insert the insert plate 1702 into the slot 1002, thereby achieving a stable connection between the test cup 10 and the housing 1701. At the same time, the spring 1703 is compressed in this position, so that the working electrode and the sealing gasket are firmly pressed against the bottom of the test cup 10, realizing the power-on conditions of the entire tooling.
[0073] In actual operation, the test cup 10 is placed into the second receiving cavity, pressed down slightly and aligned, and the insert plate 1702 is pushed into the slot 1002 of the test cup 10 to complete the clamping.
[0074] After the test is completed, simply pull out the insert plate 1702 to release the mechanical lock. At this time, the pushing force of the spring 1703 will push the used test cup 10 upward a short distance, making it easier for the robotic arm 2 to grasp and remove it.
[0075] The preload of spring 1703 ensures that the test cup 10 will not loosen throughout the test, guaranteeing the stability of the electrical connection and serving as a key foundation for achieving high-throughput continuous testing.
[0076] Preferably, such as Figure 4 As shown, the end of the test cup 10 in this application has a positioning groove 1001, and the end of the electrode assembly 12 has a positioning protrusion 1204 corresponding to the position of the positioning groove 1001. The positioning protrusion 1204 can be inserted into the positioning groove 1001 so that the electrode assembly 12 is connected to the test cup 10.
[0077] The electrode assembly 12 is connected to the test cup 10 via the insertion and engagement of the positioning protrusion 1204 and the positioning groove 1001. This is a fault-proof and precision positioning structure. The unique shape design of the protrusion and groove ensures that the electrode assembly 12 can be accurately inserted in the corresponding direction and that the insertion is complete, effectively preventing test errors caused by incomplete insertion or incorrect orientation. The housing 1201 integrates the reference electrode 1202 and the foil electrode 1203 together, forming a standard, quick-connect and removable electrode module.
[0078] During operation, the robotic arm 2 grasps the electrode assembly 12, aligns the positioning protrusion 1204 at its end with the positioning groove 1001 at the end of the test cup 10, and then inserts it vertically downwards to complete the electrical and mechanical connection.
[0079] This application simplifies electrode installation into a simple "align-insert" action, making it easy to automate. The modular design greatly simplifies electrode maintenance and replacement, while reducing connection resistance and improving signal quality.
[0080] Optionally, such as Figure 2 Combination Figure 3 As shown, the mounting bracket 16 in this application includes a first mounting plate 1601 and a second mounting plate 1602. The first mounting plate 1601 and the second mounting plate 1602 are arranged in parallel, and the horizontal height of the second mounting plate 1602 is higher than that of the first mounting plate 1601. A first slide rail 18 is installed on the first mounting plate 1601. The pressing mechanism 20 and the liquid injection mechanism 21 are both suspended on the side of the second mounting plate 1602 facing the first mounting plate 1601. A second slide rail 1605 is laid on the second mounting plate 1602. A second slider 1606 is slidably arranged on the second slide rail 1605. A support seat 1607 is provided on the second slider 1606. An isolation cover is also provided on the second mounting plate 1602. The second slider 1606 can drive the support seat 1607 to enter or leave the isolation cover.
[0081] Accordingly, such as Figure 3 As shown, the isolation cover includes a cover body 1603 and a door body 1604. The door body 1604 is slidably connected to the cover body 1603, and the door body 1604 can rise or fall in the vertical direction to open or close the cover body 1603, so that the support seat 1607 can enter or leave the cover body 1603.
[0082] The mounting bracket 16 adopts a double-layer plate structure. The first mounting plate 1601 supports the first slide rail 18. Since the first slide rail 18 needs to complete the pressing and liquid injection processes, the first mounting plate 1601 is located on the lower layer to make the overall structure more stable. The second mounting plate 1602 provides a foundation for the hoisting of the pressing mechanism 20 and the liquid injection mechanism 21, and also allows the pressing mechanism 20 and the liquid injection mechanism 21 to be positioned at a distance from one end of the first slide rail 18, thereby realizing the aforementioned pressing and liquid injection work.
[0083] After the test cup 10 is filled with saline and slow-release agent and the electrode assembly 12 is installed, it is necessary to perform power-on operation. Therefore, this application can avoid the impact on the external structure after power-on by further setting an isolation cover on the second mounting plate 1602.
[0084] In actual operation, after the assembled electrochemical assembly has been stationary for a certain period of time, the robotic arm 2 grabs it onto the carrier 1607 on the second slide rail 1605. Then the carrier 1607 moves along the second slide rail 1605, the door 1604 rises to open the cover 1603, the carrier 1607 drives the electrochemical assembly into the cover 1603, the door 1604 falls to close the cover 1603, and the power is turned on for testing.
[0085] Once the power is applied, the door 1604 opens, and the tested electrochemical component is carried out by the carrier 1607, completing the test. The robotic arm 2 first removes the electrode assembly 12, then pulls out the insert plate 1702, removes the test cup 10, imports the internal solution into the recovery box 14, and places the test cup 10 into the water tank of the cleaning mechanism 15 to clean the test cup 10. After cleaning, the robotic arm 2 returns the test cup 10 to the storage rack 4.
[0086] Preferably, there are two second slide rails 1605 in this application, which enables dual-channel operation, that is, it can simultaneously carry two assembled electrochemical components for power-on testing, thereby greatly improving the operation efficiency.
[0087] Optionally, such as Figure 1 As shown, the storage rack 4 and the mobile assembly device in this application are arranged opposite to each other at both ends of the mounting frame 1 in the length direction, and a third slide rail 101 is provided on the mounting frame 1 located between the storage rack 4 and the mobile assembly device, and the positioning end of the robotic arm 2 is slidably arranged on the third slide rail 101.
[0088] The storage rack 4 and the mobile assembly device are located at opposite ends of the mounting frame 1 along its length. The base of the robotic arm 2 is mounted on the third slide rail 101 spanning both ends, thus forming a linear production layout. The robotic arm 2 can move a wide range along the third slide rail 101, and its working range can cover all functional modules, such as the first tray 5, the second tray 6, and the third tray 7, enabling one robotic arm 2 to complete all operations, greatly reducing the complexity and cost of the equipment.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
