Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular provides a dual-station automatic flatness detection device. Background Technology

[0002] In the current production process of BTB (board-to-board) connectors, pre-clipping and inspection are generally performed manually, which presents significant efficiency and quality bottlenecks. Firstly, the force and position of manual crimping are difficult to control precisely, easily leading to poor connector contact due to incomplete crimping, severely impacting product reliability. Secondly, existing inspection equipment is limited in function, mostly confined to identifying problems and unable to perform on-site correction. After defective products are found, manual removal, re-clipping, and re-inspection are necessary, which is not only cumbersome and time-consuming but also introduces additional quality risks through multiple manual interventions. Furthermore, traditional single-station equipment can only perform one operation at a time; inspection and pressure holding processes cannot be performed concurrently, resulting in low equipment utilization and limited overall production capacity. Therefore, current technology lacks a solution that integrates automatic inspection, real-time correction, and efficient parallel processing, making it difficult to effectively improve production efficiency while ensuring quality stability. Utility Model Content

[0003] Therefore, it is necessary to provide a dual-station automatic flatness detection device to solve at least one of the technical problems in the background art.

[0004] A dual-station automatic flatness inspection device includes a frame, a worktable on the frame, and two sets of parallel placement fixtures slidably mounted on the worktable. The upper part of the frame is provided with two parallel transverse guide rails, and a first vertical sliding mechanism and a second vertical sliding mechanism are slidably mounted on the two transverse guide rails respectively. A laser detection component is mounted on the first vertical sliding mechanism, and a pressure holding component is mounted on the second vertical sliding mechanism.

[0005] Preferably, the laser detection assembly includes a detection probe and a laser displacement sensor, the detection probe and the laser displacement sensor are disposed adjacent to each other on the same mounting substrate, and the mounting substrate is connected to the output end of the first vertical sliding mechanism.

[0006] Preferably, the working ends of both the detection probe and the laser displacement sensor are positioned facing the worktable.

[0007] Preferably, the pressure holding assembly includes a pressure holding head and a pressure driving component that drives it to move vertically. The pressure driving component is connected to the output end of the second vertical sliding mechanism, and the pressure holding head is positioned facing the worktable.

[0008] Preferably, the first vertical sliding mechanism is a linear motor module, and the second vertical sliding mechanism is a ball screw module.

[0009] Preferably, the fixture has a product positioning groove, and the inner wall of the positioning groove has several limiting blocks.

[0010] Preferably, the sliding direction of the fixture, the extending direction of the transverse guide rail, and the lifting directions of the first vertical sliding mechanism and the second vertical sliding mechanism are perpendicular to each other.

[0011] Preferably, a control component is installed at the lower part of the frame, and the control component is electrically connected to the placement fixture, the transverse guide rail, the first vertical sliding mechanism, the second vertical sliding mechanism, the laser detection component, and the pressure holding component.

[0012] The beneficial effects of this utility model are as follows: 1. Closed-loop control of the laser detection and pressure-holding components replaces traditional manual crimping and judgment. The laser displacement sensor precisely measures the height of the BTB connector, and the pressure-holding component automatically performs standardized crimping operations based on the detection results. This greatly reduces quality fluctuations caused by inconsistent manual force and angle, ensures crimping flatness, reduces product failure rates due to poor contact, and significantly improves product quality consistency and long-term reliability.

[0013] 2. By innovatively integrating multiple processes such as detection, judgment, correction, and re-inspection into a single device, the entire process is automated. When a faulty crimping is detected, the device can immediately perform in-situ automatic pressure-holding correction on the production line, eliminating the need for manual removal, rework, and reloading. This solves the problems of process interruption and multiple interventions in existing technologies. This not only simplifies the operation process but also avoids additional quality risks and product damage introduced by manual transfer and secondary operations.

[0014] 3. Through a mechanical structure and control system with dual parallel operation, the detection station and the pressure holding station can work simultaneously. When one station is performing laser height measurement or information reading, the other station can simultaneously perform the pressure holding operation, allowing two time-consuming processes that originally had to be performed sequentially to be processed in parallel. This minimizes equipment idle waiting time and significantly improves equipment utilization and overall production efficiency. Attached Figure Description

[0024] Please see Figures 1 to 2This application provides a dual-station automatic flatness inspection device, including a frame 100, a worktable 200 on the frame 100, and two sets of parallel placement fixtures 300 slidably arranged on the worktable 200; two parallel transverse guide rails 400 are arranged on the upper part of the frame 100, and a first vertical sliding mechanism 500 and a second vertical sliding mechanism 510 are slidably arranged on the two transverse guide rails 400 respectively. A laser detection component 600 is arranged on the first vertical sliding mechanism 500, and a pressure holding component 700 is arranged on the second vertical sliding mechanism 510. To facilitate equipment use, the frame 100 is welded from high-strength materials, ensuring the overall rigidity and stability of the equipment. A workbench 200 is horizontally fixed in the middle of the frame 100. The workbench 200 is a flat stainless steel panel with a precision-ground surface, providing a stable bearing base for the fixtures 300 and adapting to the space requirements of testing and pressure holding operations. Specifically, in some embodiments, two sets of parallel fixtures 300 are slidably mounted on the workbench 200 via linear guide rails. The fixtures 300 can reciprocate independently along the Y-axis. The two sets of fixtures are symmetrically arranged along the length of the workbench 200, with the spacing adapted to the stroke requirements of parallel operation at two workstations. Each fixture 300 is driven by an independent transmission mechanism, which drives the fixture 300 to slide back and forth along the testing station, achieving precise switching between the testing station and the pressure holding station.

[0025] like Figure 2 As shown, in some embodiments, the upper part of the frame 100 has two parallel transverse guide rails 400 spaced a certain working distance apart, which are fixedly mounted above the worktable 200 by support seats, and their extension direction is the X-axis direction. The transverse guide rails 400 are high-precision ball linear guides, extending along the width direction of the worktable 200. The two transverse guide rails 400 are perpendicularly arranged to the sliding working areas of the two sets of fixtures 300. A first vertical sliding mechanism 500 is slidably mounted on one transverse guide rail 400, and a second vertical sliding mechanism 510 is slidably mounted on the other transverse guide rail 400.

[0026] To facilitate the use of the horizontal guide rails 400, cable chains are installed on the upper side of both horizontal guide rails 400. Specifically, the power and signal transmission required for the operation of the first vertical sliding mechanism 500 and the laser detection component 600, as well as the second vertical sliding mechanism 510 and the pressure holding component 700, are all connected via cables. A cable chain is laid parallel above each horizontal guide rail 400, and the cables required by each component are neatly stored and fixed inside the corresponding cable chain. This ensures the stability of the transmission of laser detection signals and pressure holding control commands, thereby guaranteeing the continuity of the overall equipment operation and the accuracy of the detection results from a hardware perspective.

[0027] like Figure 3As shown, the laser detection assembly 600 includes a detection probe 610 and a laser displacement sensor 620. The detection probe 610 and the laser displacement sensor 620 are disposed adjacent to each other on the same mounting plate, which is connected to the output end of the first vertical sliding mechanism 500.

[0028] The working ends of the detection probe 610 and the laser displacement sensor 620 are both positioned facing the worktable 200.

[0029] Specifically, the laser detection component 600 is fixedly connected to the output end (i.e., the mover or slider) of the first vertical sliding mechanism 500 via a mounting plate, which drives the laser detection component 600 to perform vertical movement in the Z-axis direction.

[0030] To facilitate the use of the laser detection component 600, the laser displacement sensor 610 and the detection probe 620 are fixed adjacently on the same aluminum alloy mounting base through a connector, and the working ends of both (i.e., the laser emitting end and the probe contact end) are vertically facing the area to be measured of the fixture 300 on the worktable 200 below.

[0031] In some embodiments, such as Figure 3 and Figure 5 As shown, the detection probe 620 is used to descend and contact the circuit board test point 611 after the product is loaded, to power on the product and read the version information, ensuring that subsequent test data corresponds to the specific product model. The laser displacement sensor 610 is used to measure the height of the four corners (one point near each of the four corners) of the BTB (board-to-board) connector. Further, after the detection probe 620 finishes reading the information, the probe is retracted. The laser detection component 600 is first driven upward by the first vertical sliding mechanism 500, and then moves downward, so that the laser head on the laser displacement sensor 610 emits lasers at the four corners of the BTB connector latch. The height is measured by laser sensing. The system will determine whether these four points are on the same plane. If the heights are consistent, it means that "the latching is in place", the product is qualified, and the process ends. If the heights of the four points are inconsistent (i.e., there is "floating height"), the system determines that "the latching is not in place" and proceeds to the next step of the pressure holding process.

[0032] like Figure 4 As shown, the pressure holding assembly 700 includes a pressure holding head 710 and a pressure driving component 720 that drives it to move vertically. The pressure driving component 720 is connected to the output end of the second vertical sliding mechanism 510, and the pressure holding head 710 is positioned toward the worktable 200.

[0033] Specifically, the pressure-holding component 700 is fixedly connected to the output end of the second vertical sliding mechanism 510 via a mounting base. In some embodiments, the pressure driving component 710 is preferably a cylinder, the cylinder body of which is fixedly connected to the output end of the second vertical sliding mechanism 520. A pressure-holding head fixing block is connected to the end of the piston rod of the cylinder, and the pressure-holding head 720 is detachably connected to the pressure-holding head fixing block, allowing the pressure-holding head 720 to be replaced according to different product pressure-holding requirements. Preferably, the lower end surface of the pressure-holding head 720 is a smooth, flat pressing surface, made of hard alloy and chrome-plated, to uniformly transmit pressure and resist wear. It should be noted that the lower end of the pressure-holding head 720 can also be covered with a silicone layer to avoid damaging the product. The pressure-holding head 720 moves vertically (Z-axis) under the drive of the pressure driving component 710, such as... Figure 5 As shown, the pressure-holding head 720 performs pressure-holding correction on BTB connectors with poor clamping by aligning it with the pressure-holding snap 711 of the product to be pressure-held on the placement fixture 300 and pressing it down.

[0034] The first vertical sliding mechanism 500 is a linear motor module, and the second vertical sliding mechanism 510 is a ball screw module.

[0035] In some embodiments, the first vertical sliding mechanism 500 is a linear motor module with a positioning accuracy of ±0.005mm, which is suitable for the high-precision motion requirements of the laser detection component 600; the second vertical sliding mechanism 510 is a ball screw module driven by a servo motor, which has a stable load output capability and is suitable for the pressure operation requirements of the pressure holding component 700.

[0036] The fixture 300 has a product positioning groove 310, and the inner wall of the positioning groove 310 is provided with several limiting blocks.

[0037] In some embodiments, the placement fixture 300 has a product positioning groove 310 that matches the shape of the product to be tested. The inner wall of the positioning groove 310 is provided with a plurality of rubber limiting blocks 320. The positioning groove 310 is adapted to the shape of the circuit board to achieve rapid preliminary positioning and meet the needs of rapid material loading in dual stations. The inner wall limiting blocks clamp and fix the product from the circumference to prevent the fixture from sliding, the product from shifting or shaking during testing and pressure holding, and ensure the accuracy of testing and pressure holding. The limiting blocks are made of elastic material or have rounded corners to avoid scratching the product and protect its appearance and structure.

[0038] The sliding direction of the fixture 300, the extending direction of the transverse guide rail 400, and the lifting directions of the first vertical sliding mechanism 500 and the second vertical sliding mechanism 510 are all perpendicular to each other.

[0039] Specifically, the vertical arrangement of the three components in pairs ensures that the switching of the fixture 300, the horizontal movement of the laser detection component 600 and the pressure holding component 700 driven by the transverse guide rail 400, and the lifting trajectories of the two vertical sliding mechanisms do not interfere with each other, guaranteeing that the detection and pressure holding processes can be carried out simultaneously when two workstations are in parallel. At the same time, this layout allows the laser detection component 600 to precisely align with the circuit board contact points, the laser displacement sensor 620 to align with the detection points, and the pressure holding head 710 to precisely press against the target position, significantly improving the accuracy and stability of the equipment operation and adapting to the needs of automated mass production.

[0040] The lower part of the frame 100 is equipped with a control component, which is electrically connected to the fixture 300, the transverse guide rail 400, the first vertical sliding mechanism 500, the second vertical sliding mechanism 510, the laser detection component 600, and the pressure holding component 700.

[0041] like Figure 2 As shown, to achieve overall system control of the equipment, the control component 800 is installed in the electrical control cabinet at the bottom of the frame 100. Its core components include a programmable logic controller, motion control card, power module, and human-machine interface. It coordinates and controls the actions of each actuator and processes sensor signals. In some embodiments, the control component 800 is electrically connected via cables to the drive motor of the fixture 300, the drive motor of the transverse guide rail 400, the first vertical sliding mechanism 500, the second vertical sliding mechanism 510, the laser detection component 600 (including a laser displacement sensor 610 and a detection probe 620), and the pressure drive component 720 of the pressure holding component 700. The cables are routed through wiring channels inside the frame 100 and inside the cable chain to avoid external wear. The signal interface board of the control component 800 has a reserved communication interface with external devices (such as a production line MES system), enabling real-time uploading of detection data.

[0042] In some embodiments, the complete processing procedure is as follows: First, the operator places the product with the pre-attached BTB connector into the positioning slots 310 of two placement fixtures 300 and fixes it with limiting blocks. After starting the equipment, the control component 800 controls one of the placement fixtures 300 (fixture A) to slide to the inspection station directly below the laser inspection component 600. Subsequently, the first vertical sliding mechanism 500 drives the laser inspection component 600 to descend, causing the inspection probe 620 to contact the product circuit board and read the version information; then the laser inspection component 600 rises and falls again, and the laser displacement sensor 610 measures the height of the four corners of the BTB connector. The measurement data is transmitted to the control component 800. If the calculated flatness is unqualified, the control component 800 determines that the product needs to be pressure-held.

[0043] Subsequently, the control component 800 will simultaneously control the placement fixture 300 (fixture A) to slide directly below the pressure holding component 700, and the first vertical sliding mechanism 500 will drive the laser detection component 600 to slide above another placement fixture 300 (fixture B). At this time, the pressure holding operation of one placement fixture 300 (fixture A) and the detection operation of the other placement fixture 300 (fixture B) will be carried out simultaneously. When the placement fixture 300 (fixture A) that needs to perform pressure holding reaches the pressure holding position, the control component 800 will control the second vertical sliding mechanism 510 to drive the pressure holding component 700 downward. The pressure driving component 720 drives the pressure holding head 710 to apply stable pressure to the buckle of the BTB connector for pressure holding. After the pressure holding is completed, the pressure holding component resets or continues to perform the next pressure holding.

[0044] After the products on the placement fixture 300 are inspected by the laser inspection component 600, the control system outputs a pass / fail judgment and the product is removed based on the judgment result. If the product fails, it slides to the pressure holding station to await pressure holding by the pressure holding component 700. After pressure holding, the failed products slide to the inspection station and undergo laser re-inspection by the laser inspection component 600. In this way, the two placement fixtures 300 alternately perform inspection and pressure holding, achieving parallel operation and significantly improving production efficiency.

[0045] This dual-station automatic flatness inspection equipment can achieve: (1) The closed-loop control of the laser detection component 600 and the pressure holding component 700 replaces the traditional manual crimping and judgment. The laser displacement sensor 620 performs precise height measurement of the BTB connector, and the pressure holding component 700 automatically performs standardized crimping operations based on the detection results. This greatly reduces quality fluctuations caused by inconsistent manual operation force and angle, ensures crimping flatness, reduces product failure rate due to poor contact, and significantly improves product quality consistency and long-term reliability.

[0046] (2) By innovatively integrating multiple processes such as detection, judgment, correction, and re-inspection into one device, the entire process is automated. When a faulty buckling is detected, the device can immediately perform in-situ automatic pressure-holding correction on the production line without the need for manual removal, rework, or reloading, thus solving the problems of process interruption and multiple interventions in existing technologies. This not only simplifies the operation process but also avoids additional quality risks and product damage caused by manual transfer and secondary operations.

[0047] (3) Through the mechanical structure and control system of dual-station parallel operation, the detection station and the pressure holding station can work simultaneously. When one station is performing laser height measurement or information reading, the other station can perform pressure holding operation simultaneously, so that the two time-consuming processes that originally had to be serial can be processed in parallel, minimizing the idle waiting time of the equipment and greatly improving the equipment utilization rate and overall production efficiency.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
