Description

Technical Field

[0001] The invention belongs to the field of display panel detection, and in particular relates to an integrated crimping system and a crimping method. Background Art

[0002] In the production process of display panels, the display panels need to be inspected, and the inspection process often involves actions such as crimping. The crimping equipment currently used, whether it is a turntable structure or a non-font structure, faces many challenges in the debugging process. During the design phase, the vision module and the crimping module were planned to be installed separately, and then integrated into the main line assembly and control process in the subsequent stage. The control system of the equipment generally adopts a PLC (programmable logic controller) architecture, which is tightly integrated with the main line. In this configuration, both the vision module and the crimping module need to share the PLC module with the main line (such as Figure 1 This means that the debugging of the visual module and the crimping module depends largely on the completion of the main line control process. The visual module debugging can only be started after the main line control point configuration is completed, thereby meeting the crimping debugging requirements.

[0003] In actual operation, the various functional groups on the entire line do not collaborate closely on scheduling, which makes the debugging process linear and sequential (such as Figure 2 As shown in the figure): Once the debugging of the main line body is not completed as scheduled, the crimping debugging cannot be advanced. What is more difficult is that when problems occur in the crimping debugging, the feedback process is not only lengthy and complicated, but also needs to be traced back to the previous multiple production processes and seek the assistance of various functional groups to troubleshoot the problem. This is not only time-consuming and labor-intensive, but also reduces the debugging efficiency. At the same time, the debugging process has extremely high requirements for the closeness of production planning and debugging scheduling. Any delay in manpower coordination or insufficient resource allocation will directly affect the debugging progress of the entire line body, thereby threatening the timely completion of the delivery plan. In summary, the main problems existing in the prior art can be summarized as follows: 1) The line structure of the PLC control module connecting each motor and visual unit is complex and numerous, which increases the difficulty and time cost of debugging; 2) The debugging process cannot be carried out independently of the main line, resulting in the dependence and limitations of the debugging process; 3) The lack of off-line debugging capabilities makes it impossible to perform separate testing and verification of key components such as crimping modules, thereby affecting the efficiency and accuracy of the overall debugging.

[0004] Therefore, it has become an urgent problem to improve these defects of the existing crimping system to improve the debugging efficiency and shorten the debugging cycle. Summary of the invention

[0005] In order to solve all or part of the problems of the above-mentioned prior art, the present invention provides an integrated crimping system and crimping method, which adopts an integrated architecture design, so that the system can realize independent and flexible debugging functions outside the main line body, thereby greatly improving the maintainability and operating efficiency of the system.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An integrated crimping system comprises: a human-machine interaction module, an adsorption module, a control module and at least one group of crimping modules, wherein the crimping module comprises X-direction, Y-direction and Z-direction driving mechanisms, an alignment imaging mechanism and a pressure head assembly, wherein the pressure head assembly is arranged at the output end of the Z-direction driving mechanism, and the alignment imaging mechanism is used to calibrate the position of the crimping points of the pressure head assembly and the product to be tested after photographing; the X-direction, Y-direction and Z-direction driving mechanisms are connected in series through a connecting line; the human-machine interaction module is electrically connected to the control module and the alignment imaging mechanism; the adsorption module is arranged relative to the crimping module for adsorbing and fixing the product to be tested, and the control module is used to control the movement and alignment of the pressure head assembly to crimp the product to be tested.

[0008] The crimping module also includes a θ-direction driving mechanism arranged at the output end of the Z-direction driving mechanism, and the θ-direction driving mechanism is connected to the press head assembly and is used to adjust the angle of the press head assembly so that the press head assembly is aligned with the crimping point of the product to be tested.

[0009] The power sources of the driving mechanisms in the X direction, Y direction, Z direction and θ direction are connected in series via a connecting line, and the power sources all adopt an integrated driving motor.

[0010] The adsorption module includes a carrier, an adsorption member and an exhaust assembly. At least one air inlet and at least one air outlet are arranged on the carrier. At least one air duct is arranged inside the carrier for connecting the air inlet and the air outlet. The air inlet and the air outlet on the carrier are respectively connected to the exhaust assembly and the adsorption member for controlling the suction and release of the adsorption member.

[0011] The crimping system also includes an adjustment component installed on the carrier, and the adjustment component includes a linear rail and an adjustment block arranged on the carrier. The adsorption component adjusts its installation position on the linear rail through the adjustment block to adapt to products to be tested of different specifications.

[0012] It also includes a signal generating module, which is arranged in parallel with the control module and is located below the crimping module and the adsorption module.

[0013] It also includes a switching module, which is used to connect the pressure head assembly and the signal generating module and transmit the signal of the signal generating module to the pressure head assembly.

[0014] The alignment image mechanism is arranged at the output end of the Y-direction or Z-direction driving mechanism, and the alignment image mechanism corresponds to the probe head position of the head assembly.

[0015] A crimping method using any of the above-mentioned integrated crimping systems specifically comprises the following steps:

[0016] S1. The driving mechanisms of the crimping module are assembled in sequence, and then the alignment imaging mechanism is installed at the front end of the crimping module, and the control module is installed at the bottom of the crimping module. The driving sources of the driving mechanisms of the crimping module are connected in series through a connecting wire and then electrically connected to the control module, and the alignment imaging mechanism is connected to the control module through a connecting wire;

[0017] S2. Install the fixed adsorption module, the signal generation module and the control module side by side at the bottom of the crimping module, and power on and ventilate the system;

[0018] S3. The adsorption module adsorbs and fixes the product to be tested, and adjusts the displacement of the driving mechanism in the X and Y directions in the crimping module to initially align the pressure head assembly with the connector of the product to be tested;

[0019] S4. The alignment imaging mechanism takes a picture and transmits the picture information to the control module, which performs position correction calculations, and the crimping module accurately corrects the position of the pressure head assembly according to the correction calculation results;

[0020] S5. After the correction and alignment is completed, the control module drives the Z-axis driving mechanism to press down for crimping.

[0021] The control module pre-stores the X and Y initial position parameter configuration information corresponding to different crimping products. In step S3, the displacement of the X and Y driving mechanism in the crimping module is adjusted to make the crimping head assembly and the connector of the product to be tested perform initial alignment, specifically:

[0022] The control module calls the corresponding X and Y initial position parameter configuration information according to the model of the product to be tested, and adjusts the displacement of the X and Y drive mechanism in the crimping module to complete the initial alignment of the crimping head assembly and the connector of the product to be tested.

[0023] This method significantly shortens equipment commissioning and switching time by using an integrated crimping system to perform crimping operations, thereby greatly improving production efficiency.

[0024] The present invention has at least the following beneficial effects:

[0025] 1) This application has a human-machine interaction module, an adsorption module, a control module and at least one set of crimping modules. It adopts a highly integrated architecture design, integrates the core components, and uses PC control technology to form a machine adjustment device, so that the system can be independently and flexibly debugged outside the production line. This innovative design breaks the inherent linear and sequential debugging process of the traditional crimping system, giving the debugging process higher flexibility and efficiency, significantly shortening the debugging cycle, and the comprehensive debugging time does not exceed 10 hours, thereby greatly improving the flexibility of production planning and debugging scheduling;

[0026] 2) The present application is provided with a signal generating module, and the signal of the signal generating module is transmitted to the pressure head assembly through the adapter module, so as to implement point screen testing on the product to be tested, and independent testing and production can be realized outside the main line;

[0027] 3) The present application has an adjustment component that can adjust the position of the adsorption component relative to the carrier to correspond to the connector of the product to be tested. The driving mechanisms of the crimping module are combined with the alignment imaging mechanism to adapt to products of different specifications to be tested;

[0028] 4) The power sources of the driving mechanisms of the X-direction, Y-direction, Z-direction and θ-direction of the crimping module of the present application are connected in series through a connecting line. The power sources all adopt an integrated driving motor, and then the alignment imaging mechanism is connected in series through a connecting line. Each driving mechanism of the prior art is a structure of a motor plus a driver. Each driving mechanism requires at least two connections. At the same time, each driving mechanism and alignment imaging mechanism requires a controller for control operation, which also increases the overall wiring. In addition, the driving mechanism of the prior art has the disadvantage of needing to be installed on the production line for separate debugging, and the wiring of the overall crimping structure is very much. However, each driving mechanism and alignment imaging mechanism of the present application only requires one connecting line and one controller. The simplified wiring structure makes the installation, debugging and maintenance of the system more convenient, and reduces the difficulty and cost of operation. To significantly improve production efficiency. At the same time, by adopting advanced technologies such as integrated motors, the present invention successfully achieves structural simplification and greatly reduces the occupied space. Compared with the traditional crimping mechanism, the crimping module of the present invention successfully reduces the overall size by 20% while maintaining high performance.

[0038] The technical solutions in the specific embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the embodiment of the present invention, in combination with reference Figure 3-Figure 6As shown, an integrated crimping system is provided, which mainly includes a carrier 1, an adsorption module 2, at least one group of crimping modules 3, a control module 4 and a human-computer interaction module. The carrier 1 is designed to be able to stably carry and accurately position each functional module in the system to ensure efficient collaborative operation between the components. The adsorption module 2 is installed on the carrier 1, and its main function is to use the adsorption force to fix the connector of the product to be tested to ensure the stability and position accuracy of the circuit board during the crimping process. The crimping module 3 integrates two major components: a drive module 31 and a crimping module 32. The drive module 31 has high-precision X- and Y-direction movement capabilities, and can drive the crimping module 32 to flexibly move to a specified position along a preset path. The crimping module 32 is responsible for performing the actual crimping operation, and through precise force and displacement control, achieves high-quality connection of the connector of the product to be tested. The control module 4 is not only responsible for coordinating and controlling the various operations of the adsorption module 2 and the crimping module 3 to ensure the timing coordination and action synchronization between the two, but also realizes the docking between the system and the human-computer interaction module (including computer monitors, keyboards, mice or human-computer interface devices on the production line) through the built-in communication interface, so that it can be efficiently integrated into the automated production process and improve overall production efficiency.

[0040] In this embodiment, the crimping system adopts two groups of crimping modules 3 arranged relatively to each other, which can handle more crimping tasks at the same time, or perform crimping operations at different positions; in other specific embodiments, according to actual usage, the crimping modules 3 can also be set as one group, three groups, four groups or more groups. The driving module 31 includes a guide rail 311 installed on the carrier 1 and an X-axis driving mechanism 312 and a Y-axis driving mechanism 313 sliding along the guide rail 311. The core components of the X-axis driving mechanism 312 include a first connecting portion 3121, a first screw rod 3122 and an X-axis motor 3123. The output shaft of the X-axis motor 3123 is connected to the first screw rod 3122, and the screw rod is driven to rotate by the motor. The first connecting portion 3121 integrates a slider mounted on the guide rail 311 and a first connecting nut movably mounted on the first screw rod 3122. When the first screw rod 3122 receives rotational power, the first connecting nut will move linearly along the spiral trajectory of the screw rod. This movement in turn drives the entire first connecting portion 3121 (and the crimping module 32 mounted thereon) to achieve smooth and precise displacement control in the X direction. Preferably, the first screw rods 3122 of the two groups of crimping modules 3 adopt a relative and partially overlapping staggered layout. This design not only saves space, but also enables the two groups of crimping modules 3 to operate independently without interfering with each other. In order to further optimize space utilization, the first connecting portion 3121 of each group of crimping modules 3 is designed with avoidance holes. These holes can accurately avoid the first screw rods 3122 of the other group of crimping modules 3, ensuring the stable operation of the entire system in a complex operating environment. The Y-axis driving mechanism 313 is integrated on the first connecting part 3121, and the mechanism is mainly composed of the second connecting part 3131, the second screw rod 3132 and the Y-axis motor 3133. The output shaft of the Y-axis motor 3133 is connected to the second screw rod 3132, and the second screw rod 3132 can maintain a smooth and stable rotational motion through the driving action of the Y-axis motor 3133. A second movably mounted connecting nut is provided on the second connecting part 3131, and the nut can be matched on the spiral trajectory of the second screw rod 3132. As the second screw rod 3132 rotates, the nut can efficiently convert the rotational motion into a linear displacement motion, thereby driving the second connecting part 3131 to achieve smooth and unimpeded linear movement along the spiral trajectory of the second screw rod 3132.

[0041] The crimping module 32 is designed to be detachably mounted on the second connecting portion 3131. This design enables the Y-axis driving mechanism 313 to achieve precise control of the position of the crimping module 32 in the Y direction. At the same time, the X-axis driving mechanism 312 is responsible for controlling the precise positioning of the crimping module 32 in the X direction. And the detachable design gives the system a high degree of flexibility and adaptability. Users can easily replace crimping modules 32 of different specifications or types according to actual needs to perfectly match and cope with connectors of various shapes, sizes and materials of the products to be tested, thereby greatly broadening the application scope and practicality of the system. The crimping module 32 specifically includes a pressure head assembly 321, an alignment imaging mechanism 322 and a driving unit 323. The driving unit 323 is further subdivided into a Z-axis driving mechanism and a θ-axis driving mechanism, and the two work together to achieve multi-dimensional precise control. The core components of the Z-direction drive mechanism include a Z-axis motor, a transmission member and a third screw rod, wherein one end of the transmission member is connected to the output end of the Z-axis motor, and the other end is connected to the third screw rod, and the pressure head assembly 321 is installed on the third screw rod through a connecting member, thereby achieving precise displacement in the Z direction. The θ-direction drive mechanism is mainly composed of a θ-axis motor and a synchronous pulley assembly, one end of the synchronous pulley assembly is directly connected to the output end of the θ-axis motor, and the other end cooperates with the synchronous wheel on the pressure head assembly 321, so that the θ-axis motor can transmit power to the synchronous pulley assembly, thereby driving the pressure head assembly 321 to make fine adjustments in the θ direction (i.e., the rotation direction). In other specific embodiments, the drive module 31 of the crimping module 3 can be flexibly configured with multiple first connecting parts 3121. These first connecting parts 3121 are sequentially installed on the guide rail 311 and the first screw rod 3122 in an orderly manner, thereby ensuring that they can move smoothly and accurately on a given path. Each first connection part 3121 integrates a Y-direction driving mechanism 313, which is responsible for accurately controlling the position of the crimping module 32 in the Y direction. The crimping module 32 is detachably mounted on the second connection part 3131 of the Y-direction driving mechanism 313 so as to perform crimping operations.

[0042] The adsorption module 2 includes an adjustment component 21, an adsorption member 22, an airway 26 and an exhaust component 23, wherein the airway is used to connect the adsorption member 22 and the exhaust component 23, and the exhaust component 23 is used to control the adsorption and release of the adsorption member 22. The adjustment component 21 includes a linear rail 211 and an adjustment block 212 arranged on the carrier 1, and the adsorption member 22 adjusts its installation position on the linear rail 211 through the adjustment block 212 to adapt to products to be tested of different specifications. The adsorption module 2 is used to fix the connector of the product to be tested. The adjustment component 21 flexibly adjusts the installation position of the connector on the carrier 1. In this embodiment, the adjustment component 21 also includes a bracket 24 disposed on the carrier 1, the linear rail 211 is installed on the bracket 214, and the adjustment block 212 is assembled on the slider of the linear rail 211, and can achieve smooth and precise displacement along the linear rail 211, so as to facilitate flexible adjustment of the relative position of the adjustment block 212 and their overall layout on the carrier 1. Such a design is intended to meet the fixing requirements of connectors of different sizes, shapes or production process requirements. In other specific embodiments, the form of adjusting the distance between the two adjustment blocks 212 of the adjustment component is not limited to the linear rail, but can also be other mechanical mechanisms that can achieve position adjustment. These alternatives can also support the adjustment component to achieve flexible and accurate positioning on the carrier to meet the diverse connector crimping and fixing requirements. The vacuum assembly 23 of the present application adopts a vacuum generator, and the suction and release of the adsorption member 22 are achieved by controlling the switch of the vacuum generator. When the present application is implemented in detail, when the initial debugging position of the driving mechanism is pre-stored and adjusted outside the production line, or when the crimping position of the test pressure head assembly and the connector is adjusted, the adjustment assembly only needs to adsorb and fix the connector; when the point screen test production is performed outside the production line, the product to be tested is a display screen, and when the size of the display screen is relatively large, when there are multiple connectors on the display screen, the number of adsorption modules and crimping modules is set corresponding to the number of connectors, and it is necessary to cooperate with the bearing mechanism of the display screen.

[0043] In this practical example, a locking assembly 25 is installed at least at one end of the adjustment block 212. The locking assembly 25 includes a clamping groove and a clamping plate 251 arranged on opposite sides of the end of the adjustment block 212. A threaded hole is arranged in the clamping groove and an adjusting bolt 252 is installed therein. A through hole is arranged in the clamping plate 251. The adjusting bolt 252 passes through the through hole and is threadedly connected with the threaded hole in the clamping groove. The lower end of the clamping plate 251 corresponds to the linear rail 211. The clamping plate and the linear rail are clamped or loosened by screwing the adjusting bolt in or out of the threaded hole.

[0044] In this embodiment, a plurality of adsorption cavities are arranged on the surface of the adjustment block 212, and an adsorption member 22 can be installed in each adsorption cavity. These adsorption members 22 are designed to be in close contact with the connector of the product to be tested. The adsorption member 22 includes a suction cup 221 and an air inlet pipe 222 connected to the suction cup 221. A through hole for the air inlet pipe to pass through is provided on the adjustment block 212, and the air inlet pipe is connected to the vacuum generator so that the suction cup can suck and release the connector. In the specific implementation of this application, at least one air inlet 11 and at least one air outlet are provided on the carrier 1, and at least one air duct is provided inside the carrier for connecting the air inlet and the air outlet. The air inlet and the air outlet on the carrier are respectively connected to the vacuum generator and the air inlet pipe 222 of the adsorption member 22. The vacuum generator 23, the air inlet 11, the air duct, the air outlet and the air inlet pipe 222 of the adsorption member 22 form a complete negative pressure adsorption system through the pipeline. In another embodiment of the present application, the air outlet on the carrier 1 is installed with an adapter 12 connected to the air inlet pipe of the adsorbent 22, or the air outlet on the carrier is installed with a control valve to control the start and stop of the adsorption operation. When the vacuum generator 223 is working, a strong negative pressure effect will be generated, which will be transmitted to each adsorbent 22 of the adjustment block 212 through the airway, so that the adsorbent 22 can tightly and firmly adsorb the connector to be crimped. This design ensures that the connector can remain stable during the crimping process and avoids the risk of displacement or falling off. It is worth noting that the implementation method of the vacuum assembly in the present invention is not limited to vacuum adsorption. In practical applications, other mechanical fixing methods (such as clamps, buckles, etc.), magnetic adsorption, electrostatic adsorption or other innovative fixing technologies can also be used according to the characteristics and fixing requirements of the product to be tested, as long as these methods can effectively achieve a stable fixation of the product to be tested. Such design flexibility provides a wide range of applicability and scalability for the application of the adsorption module.

[0045] The integrated crimping system of the present invention can be further provided with a signal generating device 5, which is arranged together with the control module 4 on the bottom surface of the carrier 1, and the signal generating device 5 is located on one side of the control module 4. An electrical connection is established between the signal generating device 5 and the pressure head assembly 321, and this design is intended to be used for the point screen test process after the crimping process of the product to be tested is completed. Specifically, the core structure of the signal generating device 5 includes a graphic signal generator / signal generator (PG, Pattern Generator) and at least one PG extension box. The main function of the graphic signal generator is to generate and output a series of test signals, which are necessary for performing the point screen test and can simulate various signal input conditions that the product may encounter in actual use. The PG extension box plays the role of signal expansion and enhancement. It can receive signals from the signal generator and further process and distribute the signals according to the test requirements, such as signal amplification, shaping, and distribution to multiple test points, so as to ensure that the test signal can be accurately and efficiently transmitted to the pressure head assembly 321, and then act on the product to be tested.

[0046] See also Figure 3 , 4 , the adapter module 6 includes an adapter 61 and a flexible circuit board 62. The adapter 61 is plug-connected to the signal generating device 5, and the flexible circuit board 62 is electrically connected to the pressure head assembly. When the present application is implemented, the crimping module has two groups, and the adapter module 6 is located between the crimping modules, which is used to connect the pressure head assembly and the signal generating module, and transmit the graphic signal of the signal generating module to the pressure head assembly. By integrating the signal generating device 5 into the crimping system and directly electrically connecting it to the pressure head assembly 321, the present invention realizes the function of performing point screen detection immediately after the debugging crimping process is completed, without transferring the product or adding additional testing equipment. This design greatly simplifies the testing process, shortens the product testing cycle, and significantly improves the overall production efficiency.

[0047] The alignment image mechanism 322 is arranged at the output end of the Y-axis driving mechanism or the Z-axis driving mechanism, and corresponds to the position of the probe pressure head of the pressure head assembly 321. In this embodiment, the alignment image mechanism 322 is specifically installed at the output end of the Z-axis driving mechanism so that when performing detection or positioning tasks, accurate visual alignment and monitoring of the probe pressure head can be achieved.

[0048] In order to achieve efficient collaborative operation among the motors, the X-axis motor 3123, the Y-axis motor 3133, the Z-axis motor and the θ-axis motor all adopt advanced bus control communication methods, and they are connected and communicated with the central control module 4 through a unified communication protocol and a single communication network cable. By adopting the innovative design of an integrated drive motor, compared with the traditional crimping mechanism, the overall size of the crimping module 32 is successfully reduced by 20% while maintaining high performance. This significant optimization not only improves the compactness and portability of the equipment, but also provides more possibilities for its application in a small space. The adsorption module 2 is mainly composed of a linear rail 211, a plurality of adsorption components 22 and a vacuum generator 23. The linear rail 211 is arranged on the carrier 1, providing a stable and precise moving path for the adsorption component 22. Multiple adsorption components 22 are installed on the linear rail 211 and can move smoothly along the linear rail 211. These adsorption components 22 are closely connected to the vacuum generator 23, through the negative pressure effect generated by the vacuum generator 23. The adsorption component 22 can firmly adsorb the connector of the product to be tested to ensure that it will not be displaced or fall off during the crimping process.

[0049] The control module 4 uses an advanced PC (personal computer) architecture as the core control system and has a built-in high-performance main controller. The main controller establishes stable and efficient communication connections with the drive modules 31 and the crimping modules 32 in the plurality of crimping modules 3 through dedicated and independent communication cables. Figure 6 As shown, the main controller is connected in series to the X-, Y-, θ- and Z-direction drive mechanisms in the crimping module 3 through an independent communication network cable, so as to achieve precise coordination and control of the movements of these drive mechanisms and ensure the accurate execution of the crimping operation. At the same time, in order to ensure the real-time and accuracy of the visual data, the alignment imaging mechanism 322 in the crimping module 3 is connected in series through another completely independent communication network cable. This design ensures that the data collected by the alignment imaging mechanism 322 can be quickly and without delay transmitted to the main controller for processing, thereby further improving the accuracy and efficiency of the crimping operation. At the software level, the visual software is seamlessly integrated into the PC control system to form a unified and coordinated control platform. The PC axis control software interface is standardized to make the operation more intuitive and convenient. Based on the above design, the present invention adopts an innovative method of parallel design and assembly / debugging of the crimping system and the main line body. As Figure 7As shown in the figure, this method allows the debugging and preparation of the crimping system to be carried out independently of the progress of the main line, thereby greatly shortening the overall production preparation cycle. After integrating the vision and control software, the crimping system can be independently debugged in advance outside the main line. When problems occur during the crimping debugging process, due to the modularity and independence of the system design, the scope of investigation is effectively narrowed, and the content of investigation is also reduced accordingly, thereby further improving the debugging (production) efficiency.

[0050] See also Figure 7 , 8 As shown, the present invention also provides a crimping method, which is implemented based on the integrated crimping system described above and specifically includes the following steps:

[0051] S1. The driving mechanisms of the crimping module 3 are assembled in sequence, and then the alignment imaging mechanism 322 is installed at the front end of the crimping module 3, and the control module 4 is installed at the bottom of the crimping module 3. The driving sources of the driving mechanisms of the crimping module 3 are connected in series through a connecting line and then electrically connected to the control module 4, and the alignment imaging mechanism 322 is connected to the control module 4 through the connecting line;

[0052] S2. Install the carrier 1 and the fixing mechanism 22, the signal generating device 5 and the control module 4 are installed side by side at the bottom of the crimping module 3, and the system is powered and ventilated;

[0053] S3. The fixing mechanism 22 fixes the product to be tested, and adjusts the displacement of the driving mechanism in the X and Y directions of the crimping module 3, so that the pressure head assembly 321 and the connector of the product to be tested are initially aligned;

[0054] S4. The alignment imaging mechanism 322 takes a picture and transmits the picture information to the control module 4, which performs position correction calculations, and the crimping module 3 accurately corrects the alignment of the pressure head assembly 321 according to the correction calculation results;

[0055] S5. After the correction and alignment is completed, the control module 4 drives the Z-axis driving mechanism to press down for crimping.

[0056] The control module 4 pre-stores the X and Y preliminary position parameter configuration information corresponding to different crimping products. In step S3, the displacement of the X and Y driving mechanism in the crimping module 3 is adjusted to make the pressure head assembly 321 and the connector of the product to be tested perform initial alignment. Specifically, the control module 4 calls the corresponding X and Y preliminary position parameter configuration information according to the model of the product to be tested, and adjusts the displacement of the X and Y driving mechanism in the crimping module 3 to complete the initial alignment of the pressure head assembly 321 and the connector of the product to be tested.

[0057] In this embodiment, the connector to be crimped and connected to the product is placed on the adsorption module 2 so that the connector is located above the adsorption component 22, and then the vacuum generator 23 is started to fix the connector at a predetermined position; the control module 4 receives the crimping instruction sent by the main production line through the communication interface, and after parsing the instruction content, sends a control signal to the drive module 31 of the crimping module 3 to drive the X-direction drive mechanism 312 and / or the Y-direction drive mechanism 313 to perform fine adjustments in the X and Y directions, so that the crimping module 32 moves to the specified crimping position; after the crimping module 32 reaches the specified position, the alignment imaging mechanism 322 is started to capture and process the image to determine the actual position of the connector; if the crimping angle needs to be adjusted, the θ-direction drive mechanism 312 is used ... According to the feedback from the alignment imaging mechanism 322, the mechanism drives the ram assembly 321 to make fine adjustments in the θ direction through the cooperation of the θ-axis motor and the synchronous pulley assembly to achieve the actual crimping angle; after confirming the crimping angle, the Z-axis drive mechanism receives the control signal and drives the ram assembly 321 to move in the Z direction through the Z-axis motor, so that the ram assembly 321 contacts the connector and applies a predetermined crimping force to complete the crimping operation; the product undergoes the lighting and inspection process, and after completion, the Z-axis drive mechanism raises the ram assembly 321, the Y-axis drive mechanism 313 returns to the initial standby position, the adsorption module 2 releases the adsorption force on the connector, the downstream robot transports the inspected product away, and the upstream robot re-places a piece of product at the crimping station.

[0058] The above-mentioned crimping method is applicable to the off-line debugging stage, and can also be applied to the crimping stage during the actual production process on the production line.

[0059] The present invention cleverly integrates core components such as the adsorption module 2, the crimping module 3 and the control module 4 into an integrated architecture by adopting a highly integrated design. This design not only simplifies the overall structure of the system, but also significantly improves the collaborative efficiency between the functional modules. At the same time, the crimping module 32 adopts a detachable design, so that users can easily replace the crimping modules 32 of different specifications or types to cope with connectors to be crimped of various shapes, sizes and materials. This modular design greatly broadens the application range of the system and gives it a high degree of flexibility and adaptability. In addition, the integration into the integrated architecture also realizes the function of off-line independent debugging, so that the independent structure can complete the off-line debugging one week before the main line body, thereby effectively shortening the equipment debugging and cutting time, and further improving production efficiency. Compared with the traditional crimping mechanism, the crimping module 32 of the present invention successfully reduces the overall size by 20% while maintaining high performance. This significant optimization not only improves the compactness and portability of the equipment, but also provides more possibilities for its application in a small space. In addition, through space optimization measures such as carefully designed avoidance holes and relative and partially overlapping staggered layouts, the present invention also ensures that the two groups of crimping modules 3 can operate independently without interfering with each other, thereby further improving the overall performance and stability of the system.

[0060] The integrated crimping system of the present invention is designed for the integrated manufacturing process of small and medium-sized LCD panels and other display panels, and exhibits extremely high applicability and efficiency. The system not only perfectly meets the needs of integrated testing technology for small and medium-sized LCD display panels, but is also widely applicable to all precision operations such as automatic wiring and automatic crimping, providing a more advanced and reliable solution for connector crimping.

[0061] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention. These improvements and modifications also fall within the scope of protection of the claims of the present invention.
