Description

Technical Field

[0001] This utility model is a multi-point pressing and adjusting mechanism, belonging to the technical field of display screen testing equipment. Background Technology

[0002] In the field of high-precision electronics manufacturing, especially in the production of TFT-LCD panels, the increasing resolution of display panels and the shrinking panel pitch have significantly increased the precision requirements for the lamination process. Modern display panel production often requires multiple lamination operations to achieve a reliable connection between the FPC (flexible printed circuit board) and the panel. This type of process places stringent demands on the precise positioning of lamination points, the uniform distribution of lamination force, and the rapid switching between different product models.

[0003] Traditional crimping processes generally use fixed crimping fixtures. After clamping and fixing, the equipment will vibrate during use, and attention needs to be paid to the clamping status. Different specifications of products require special crimping fixtures, resulting in a large number of fixtures and complicated management. Because a large number of specialized fixtures require dedicated storage space, production site costs are increased. Furthermore, when changing products, the entire set of fixtures must be replaced, which takes a long time to disassemble and reassemble, seriously affecting the efficiency of production line changeover. Each set of specialized fixtures needs to be designed and manufactured independently, which greatly increases equipment investment costs. The large number of fixtures can easily lead to loss or misuse, affecting production quality and consistency.

[0004] This is particularly prominent in the modern electronics manufacturing environment of small-batch, multi-variety production, which severely restricts production efficiency and cost control. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-point pressing and adjusting mechanism to solve the problems of the existing technology.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A multi-point crimping adjustment mechanism, comprising: A slide rail fixing plate is installed on the machine base, and two X-axis guide rails and guide rail blocks are installed on the slide rail fixing plate; Multiple sets of needle mold adjustment seats, wherein the needle mold adjustment seats are slidably mounted on sliders of two X-axis guide rails; A needle mold connecting seat, wherein the needle mold connecting seat is positioned and installed on the needle mold adjusting seat by a positioning pin; A crimping needle die, wherein the crimping needle die is fixed on a needle die connecting seat; A straight-lined handle, wherein the straight-lined handle is used to press and fix the needle mold adjusting seat onto the slide rail fixing plate by means of a nut; By rotating the straight-lined handle, the gap between the needle die adjustment seat and the slide rail fixing plate increases, and the pressure decreases. By pushing the needle die adjustment seat laterally, it moves laterally along the X-axis guide rail, thereby adjusting the pressing needle die to the required pressing position.

[0007] As a further improvement, a pressure sensor is provided below the crimping die to detect the state of the crimped workpiece; A dynamic monitoring unit is installed on the slider, located between the slider and the X-axis guide rail, for real-time monitoring of the slider's movement status. It also includes a control module, which is electrically connected to the pressure sensor and the dynamic monitoring unit. In operation, when the pressure sensor is continuously triggered and when the dynamic monitoring unit is triggered, the control module sends an offset signal toward the receiving terminal.

[0008] As a further improvement, the nut is an M4 nut, and the slide rail fixing plate is provided with a T-slot. The M4 nut is placed in the T-slot, and the straight-line handle presses and fixes the needle mold adjusting seat to the slide rail fixing plate by screwing in the M4 nut. The cooperation between the T-slot and the M4 nut constitutes an anti-loosening structure.

[0009] As a further improvement, it also includes an FPC and an adapter board; one end of the FPC is fixed on the crimping die, and the other end is fixed on the adapter board, for signal transmission or circuit connection.

[0010] As a further improvement, the locating pin is a rhomboid locating pin or a cylindrical locating pin.

[0011] As a further improvement, the grooved handle is a manual knob handle, and its engagement with the nut includes anti-loosening threads or anti-loosening washers.

[0012] As a further improvement, an elastic pad is provided between the needle mold adjustment seat and the slider of the X-axis guide rail.

[0013] As a further improvement, the slide rail fixing plate is a metal plate with multiple T-slots. The T-slots are used to accommodate nut installation and position adjustment, and the slide rail fixing plate is fixed to external equipment by bolts.

[0014] As a further improvement, the needle die connecting seat is fixedly connected to the crimping needle die by bolts, and the bolts are coated with anti-loosening adhesive.

[0015] Beneficial effects: This invention addresses the problems of high jig redundancy, large space occupation, low conversion efficiency, high cost, and high management risk in existing technologies through a modular and adjustable crimping mechanism. This solution abandons the traditional fixed crimping jig approach and adopts a "one machine, multiple adjustments" design concept. By combining an X-axis guide rail system with an adjustable needle die assembly, a single mechanism can adapt to the crimping needs of multiple product specifications, fundamentally eliminating the need for a large number of dedicated jigs.

[0016] By employing an intuitive and efficient operating procedure, operators only need to rotate and loosen the straight-line handle, manually push the die adjusting seat laterally along the X-axis guide rail to the target position, and then lock the straight-line handle to complete single-point positioning. For multi-point crimping requirements, this operation can be repeated to adjust the position of each crimping die in sequence.

[0017] The X-axis guide rail system provides high-precision linear guidance, and the quick-locking mechanism of the straight-line handle enables micron-level position adjustment, meeting the precision pressing requirements of high-resolution display panels.

[0018] The pin die connector is precisely positioned with the pin die adjustment seat via a positioning pin. The crimping pin die can be designed in a standardized manner, realizing a flexible production mode with one set of hardware and multiple applications.

[0019] When switching products, there is no need to replace the entire set of fixtures; only the positions of each crimping point need to be adjusted, reducing the fixture replacement time from several hours to several minutes. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Reference Figure 1-7 As shown, a multi-point crimping adjustment mechanism includes: A slide rail fixing plate 1 is installed on the machine base 11. Two X-axis guide rails 2 and guide rail blocks 3 are installed on the slide rail fixing plate 1. Multiple sets of needle mold adjustment seats 4, wherein the needle mold adjustment seats 4 are slidably mounted on the sliders 21 of the two X-axis guide rails 2; Needle mold connecting seat 5, which is positioned and installed on needle mold adjusting seat 4 by positioning pin 7; A crimping needle die 6 is fixed on a needle die connecting seat 5; The straight-lined handle 8 is used to press and fix the needle mold adjusting seat 4 onto the slide rail fixing plate 1 by means of nut 9; By rotating the straight-lined handle 8, the gap between the needle die adjustment seat 4 and the slide rail fixing plate 1 increases, and the pressure decreases. By pushing the needle die adjustment seat 4 laterally, it moves laterally along the X-axis guide rail 2, thereby adjusting the crimping needle die 6 to the required crimping position.

[0032] By adopting a modular and adjustable design, this solution addresses the problems of high jig redundancy, large space occupation, low conversion efficiency, high cost, and high management risk in existing technologies. It abandons the traditional fixed crimping jig approach and adopts a "one machine, multiple adjustments" design concept. Through the combination of the X-axis guide rail system and the adjustable needle die assembly, a single mechanism can adapt to the crimping needs of multiple product specifications, fundamentally eliminating the need for a large number of dedicated jigs.

[0033] By employing an intuitive and efficient operating procedure, operators only need to rotate and loosen the straight-line handle 8, manually push the needle die adjusting seat 4 laterally along the X-axis guide rail 2 to the target position, and then lock the straight-line handle 8 to complete single-point positioning. For multi-point crimping requirements, this operation can be repeated to adjust the position of each crimping needle die 6 in sequence.

[0034] The X-axis guide rail 2 system provides high-precision linear guidance, and the straight-line handle 8 provides a quick-locking mechanism to achieve micron-level position adjustment, meeting the precision pressing requirements of high-resolution display panels.

[0035] The needle die connector 5 is precisely positioned with the needle die adjusting seat 4 via the positioning pin 7, and the pressing needle die 6 can be designed in a standardized manner to achieve a flexible production mode with one set of hardware and multiple applications.

[0036] When switching products, there is no need to replace the entire set of fixtures; only the positions of each crimping point need to be adjusted, reducing the fixture replacement time from several hours to several minutes.

[0037] A single adjustment mechanism replaces multiple sets of specialized fixtures, significantly reducing the need for storage space and improving the utilization rate of production line space.

[0038] Compared to traditional fixed crimping fixtures, this solution represents a leap from rigid matching to flexible adaptation. In traditional solutions, each product specification requires a dedicated fixture, while this mechanism, through its adjustable design, allows the crimping die 6 to be flexibly configured according to actual needs, achieving multi-purpose functionality. This avoids the high costs of designing and manufacturing crimping fixtures individually for each product; the crimping die 6 can be standardized for production, significantly reducing fixture procurement and maintenance costs.

[0039] Product changeover time has been reduced from several hours to less than 10 minutes, greatly improving production line flexibility and responsiveness, and adapting to small-batch, multi-variety production models. Standardized crimping needle dies and precise adjustment mechanisms ensure consistent crimping positions, reducing positioning errors caused by fixture changes. The significantly reduced number of fixtures lowers the complexity of fixture management and the risk of loss, achieving optimized allocation of production resources.

[0040] It also includes an FPC and an adapter board; one end of the FPC is fixed to the crimping pin mold 6, and the other end is fixed to the adapter board, used for signal transmission or circuit connection. The FPC is the control module 15.

[0041] The integrated configuration of FPC (Flexible Printed Circuit) and adapter board solves the signal transmission challenge in multi-point crimping. One end of the FPC is firmly connected to the crimping die 6, while the other end precisely connects to the adapter board, forming a complete signal transmission path. The flexible circuit board's characteristics allow it to adapt to minute displacements and stress changes during crimping, avoiding the breakage risk associated with rigid connections. The adapter board, as a standardized interface, enables rapid switching of signal connections between products of different specifications without the need for rewiring or replacement of connecting components. This configuration allows crimping and signal testing to be completed simultaneously, significantly shortening the testing cycle and improving production efficiency. During high-precision crimping, the FPC is directly integrated into the crimping die 6, ensuring the stability and reliability of signal transmission and effectively solving problems such as poor contact and signal interference caused by traditional separate connections.

[0042] Example 2 This embodiment is a further improvement on embodiment 1. The nut 9 is an M4 nut 9. The slide rail fixing plate 1 is provided with a T-slot 12. The M4 nut 9 is placed in the T-slot 12. The straight-line handle 8 presses and fixes the needle mold adjusting seat 4 on the slide rail fixing plate 1 by screwing in the M4 nut 9. The cooperation between the T-slot 12 and the M4 nut 9 constitutes an anti-loosening structure.

[0043] The T-slot 12 on the slide rail fixing plate 1, in conjunction with the M4 nut 9, constitutes a crucial anti-loosening mechanism. The T-slot 12 structure allows the M4 nut 9 to slide freely within the slot while effectively restricting its rotational freedom. When the threaded handle 8 is screwed into the M4 nut 9, the bottom of the nut 9 forms a surface contact with the bottom of the T-slot 12, generating a stable supporting force and avoiding the positioning failure problem caused by the easy rotation of the nut 9 in traditional fixing methods.

[0044] This structure effectively resists vibration and external forces during equipment operation, ensuring that the needle die adjusting seat 4 remains absolutely stable in the locked state and preventing positional displacement due to loosening during the crimping process. Operators only need to loosen the straight-line handle 8; the M4 nut 9 can then slide smoothly within the T-slot 12, adjust to the target position, and then re-tighten, achieving rapid and accurate positioning while avoiding precision loss caused by frequent disassembly and assembly.

[0045] As a further improvement, the positioning pin 7 is a rhomboid positioning pin 7 or a cylindrical positioning pin 7. The grooved handle 8 is a manual knob handle, and its cooperation with the nut 9 includes anti-loosening threads or anti-loosening washers. An elastic washer 16 is provided between the needle die adjusting seat 4 and the slider 21 of the X-axis guide rail 2.

[0046] The differentiated application of the rhomboid locating pin 7 and the cylindrical locating pin 7 meets the needs of different precision scenarios. The rhomboid locating pin 7, through a single-sided positioning mechanism, ensures accurate positioning in the X / Y directions while allowing thermal expansion compensation in the Z direction, effectively solving the problem of stress accumulation caused by temperature changes, and is particularly suitable for production scenarios with large fluctuations in ambient temperature.

[0047] The cylindrical locating pin 7 provides omnidirectional high-precision repeatability, ensuring that the consistency error of the pin mold connector 5 during each installation is controlled within the micrometer level, meeting the stringent requirements of high-resolution display panels for the crimping position. Operators can quickly select the appropriate type of locating pin 7 according to product specifications to achieve precise docking between the pin mold connector 5 and the pin mold adjustment seat 4, eliminating the need for repeated adjustments and reducing the traditional positioning process that takes several minutes to several seconds, significantly improving production line changeover efficiency.

[0048] The combination of a manual rotary knob handle and an anti-loosening thread or anti-loosening washer achieves a perfect balance between ease of operation and reliable locking. The ergonomic rotary handle allows operators to tighten or loosen the lock without any tools, significantly reducing operational difficulty and time costs.

[0049] The anti-loosening thread or anti-loosening washer structure effectively resists the continuous vibration during equipment operation, prevents accidental loosening in the locked state, and ensures that the crimping die 6 remains absolutely stable during operation. This combination solves the contradiction of "looseness leads to instability, tightness leads to difficulty in adjustment" in traditional fastening methods, making the crimping position adjustment both quick and reliable, and is particularly suitable for production environments with high-frequency product changeovers.

[0050] A crucial buffer layer is formed by an elastic shim 16 placed between the die adjusting seat 4 and the slider 21 of the X-axis guide rail 2. This shim effectively absorbs high-frequency vibrations during equipment operation, reduces interference with the precision crimping process, and avoids crimping position misalignment caused by vibration.

[0051] Meanwhile, the elastic shim 16 can compensate for minor assembly errors between the guide rail and the slider 21, improving overall motion stability and ensuring the linearity and repeatability of the needle die adjustment seat 4 when sliding on the X-axis guide rail 2. Furthermore, this structure reduces friction and wear caused by direct metal-to-metal contact, significantly extending the service life of the guide rail system and reducing equipment maintenance frequency and downtime. Operators experience a smoother operating feel during adjustment, further improving adjustment accuracy and efficiency.

[0052] As a further improvement, the slide rail fixing plate 1 is a metal plate with multiple T-slots 12. The T-slots 12 are used to accommodate the installation and position adjustment of the nuts 9, and the slide rail fixing plate 1 is fixed to the external equipment by bolts. The needle die connecting seat 5 is fixedly connected to the crimping needle die 6 by bolts, and the bolts are coated with anti-loosening adhesive.

[0053] The slide rail fixing plate 1, made of high-strength metal, provides excellent structural rigidity and thermal stability, effectively resisting deformation and thermal stress during processing. Multiple precision-machined T-slots 12 on the plate surface not only serve as mounting rails for the M4 nut 9, but also constitute a complete stepless adjustment system, allowing the needle die adjusting seat 4 to be precisely locked in any position.

[0054] The special geometry of the T-slot 12 ensures that the nut 9 will not rotate under locking force, while allowing free sliding along the slot, achieving both flexibility in position adjustment and reliable locking. The slide rail fixing plate 1 is firmly connected to the external equipment by high-strength bolts, forming a stable reference platform to ensure absolute stability of the entire crimping system during operation, avoiding loss of crimping accuracy due to base platform sway. Operators can flexibly select any position in the T-slot 12 for the installation and positioning of the needle die adjustment seat 4 according to different product specifications, adapting to diverse crimping needs without replacing any components.

[0055] By applying professional anti-loosening adhesive to the connecting bolts between the die connector 5 and the crimping die 6, a durable and reliable chemical locking mechanism is formed.

[0056] This technology effectively solves the problem of mechanical connection loosening caused by continuous vibration during long-term equipment operation, ensuring that the crimping needle die 6 maintains a precise position at high frequency. The anti-loosening adhesive forms an elastic sealing layer between the threads, not only preventing loosening but also blocking contaminants from entering and extending the service life of the connectors. Compared with traditional mechanical anti-loosening methods, the anti-loosening adhesive provides a more uniform locking force distribution, avoiding fretting wear caused by localized stress concentration.

[0057] In practical applications, operators only need to tighten the bolts to the standard torque, and the anti-loosening adhesive will provide a long-term reliable locking effect after curing, eliminating the need for periodic inspections and retightening, thus significantly reducing equipment maintenance frequency and downtime. This connection method ensures that the crimping die 6 maintains positional accuracy during tens of thousands of crimping cycles, making it particularly suitable for high-precision, high-frequency electronic manufacturing environments.

[0058] Anti-loosening adhesive is an anaerobic chemical locking agent specifically designed for threaded connections, belonging to a high molecular polymer material system. Its core characteristic lies in its curing reaction in an oxygen-free environment. When applied to the thread gap and isolated from air, it forms a tough cross-linked polymer structure through catalytic interaction with the metal surface.

[0059] This material plays a dual role in bolted connections: firstly, after curing, it forms an elastic adhesive layer that effectively fills the microscopic gaps between threads, providing a uniformly distributed locking force; secondly, it possesses excellent damping characteristics, absorbing vibration energy and preventing fretting wear and loosening caused by equipment vibration. Compared to traditional mechanical anti-loosening methods such as spring washers and double nuts, this anti-loosening adhesive provides a more uniform distribution of locking force, avoiding localized stress concentration problems, while not adding extra assembly space.

[0060] In practical applications, the anti-loosening adhesive is applied to the threaded surface of the connecting bolts. After tightening to the standard torque, the adhesive cures within the sealed thread gaps, forming a durable and reliable locking effect. This technology is particularly suitable for precision instruments such as electronic manufacturing equipment, ensuring the stability of critical connections under long-term vibration environments. It effectively prevents accuracy drift caused by loose connections, significantly reduces equipment maintenance frequency and downtime, and substantially improves the stability of the production process and the consistency of product quality.

[0061] Example 3 This embodiment differs from the fixing mechanism in Embodiment 2 by incorporating an alarm component. A pressure sensor 13 is located below the crimping needle mold 6 to detect the status of the crimped workpiece. The dynamic monitoring unit 14 is installed on the slider 21 and is located between the slider 21 and the X-axis guide rail 2. It is used to monitor the movement state of the slider 21 in real time. It also includes a control module 15, which is electrically connected to the pressure sensor 13 and the dynamic monitoring unit 14. In operation, when the pressure sensor 13 is continuously triggered and when the dynamic monitoring unit is triggered, the control module 15 sends an offset signal toward the receiving terminal 17.

[0062] In high-precision crimping processes, traditional fixed crimping fixtures inevitably generate mechanical vibrations during equipment operation, leading to two major problems: First, vibrations cause slight displacements in the die position during crimping, directly affecting the crimping accuracy of micro-pitch components; second, the lack of a real-time status monitoring mechanism prevents timely intervention in the early stages of crimping abnormalities, often resulting in batch product quality issues. This is especially true in the production of high-resolution display panels where the pitch has been reduced to the micrometer level; even minute positional deviations can cause poor circuit connections, severely impacting product yield.

[0063] The pressure sensor 13 integrated beneath the crimping die 6 captures force changes in real time during the crimping process, accurately monitoring the contact state and pressure distribution of the crimped workpiece. This sensor, together with the dynamic monitoring unit 14 mounted on the slider 21, forms a complementary monitoring network. The latter detects minute positional changes caused by vibration or external forces by precisely measuring the relative displacement between the slider 21 and the X-axis guide rail 2. Both data streams are synchronously transmitted to the central control module 15 for real-time analysis and processing, forming a complete closed-loop monitoring system for the crimping process.

[0064] The control module 15 employs a dual-judgment logic: when the pressure sensor 13 continuously triggers, indicating that the crimping action is in progress, and simultaneously, when the dynamic monitoring unit 14 detects a positional offset exceeding a threshold, the system immediately sends an offset signal to the receiving terminal 17. This mechanism effectively solves the quality control problem of "post-processing discovery and batch scrapping" in traditional crimping processes. Operators can obtain real-time equipment status information during the crimping process, and once the system issues an early warning, production can be immediately suspended and the equipment inspected to prevent the continued production of defective products.

[0065] In practical applications, this monitoring system improves the stability of crimping position accuracy by more than 40%, reduces the crimping defect rate caused by vibration to below 0.05%, and significantly improves the production yield and consistency of high-resolution display panels.

[0066] The dynamic monitoring unit 14 employs a high-precision micro-displacement sensor, specifically a combination of an inductive displacement sensor and a miniature accelerometer. The inductive displacement sensor, based on the principle of electromagnetic induction, accurately detects the relative displacement between the slider 21 and the guide rail by measuring changes in coil inductance, achieving a resolution of 0.1 μm. The miniature accelerometer, based on the piezoelectric effect or MEMS technology, captures real-time changes in the vibration acceleration of the slider 21 along the X-axis. These two types of sensors work together; the former monitors static position shifts, while the latter monitors dynamic vibration characteristics, together forming a complete motion state monitoring network.

[0067] The monitoring unit is precisely installed at the critical interface between the slider 21 and the X-axis guide rail 2, directly sensing the relative motion between them. When the equipment is running normally, the sensor continuously outputs a reference signal; once abnormal vibration or positional displacement occurs during the crimping process, the sensor immediately detects a signal change exceeding a preset threshold. In practical applications, this unit, together with the pressure sensor 13 below the crimping die 6, forms a dual verification mechanism: when the pressure sensor 13 confirms that the crimping action is in progress (continuous trigger state), and the dynamic monitoring unit 14 detects an abnormal displacement signal, the control module 15 determines that there is a risk of crimping position displacement and immediately sends a warning signal to the receiving terminal 17.

In terms of the technical aspects of this design principle, the settings of the dynamic mechanism, power supply system and control system of the device are not fully described. However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its dynamic mechanism, power supply system and control system can be clearly understood.
