Description

Technical Field

[0001] This invention belongs to the field of automation equipment technology, and in particular relates to an automatic connector inspection and packaging machine and its working method. Background Technology

[0002] Connectors are core components in electronic devices, precision instruments, and communication equipment. Their dimensional accuracy, appearance integrity, and electrical conductivity directly determine the stability of the terminal equipment. After mass production of connectors, a series of processes must be completed, including marking, electrical performance testing, dimensional inspection, appearance defect inspection, defective product sorting, sampling re-inspection, and automated packaging. Currently, traditional connector testing and packaging equipment on the market has many technical shortcomings, which seriously restrict production efficiency and product yield. Specific problems are as follows:

[0003] 1. In the process of transferring and transporting products at the workstation, traditional testing and packaging equipment directly places the connectors on the fixed support to complete the docking and transfer. The material is in hard contact with the support, which makes it very easy to scratch the surface of the connector during handling and positioning, causing secondary damage to the product, affecting the appearance quality and dimensional accuracy of the product, and resulting in a high product defect rate.

[0004] 2. Traditional equipment adopts a serial operation mode in which all workstations are moved and relocated first, and then CCD size and appearance inspection is carried out uniformly. The inspection station has a long waiting time, the equipment idle rate is high, the process connection is blocked, and parallel operation of workstations cannot be realized. The overall production efficiency of the equipment is low and it is difficult to adapt to the needs of mass production.

[0005] 3. Traditional packaging equipment is only equipped with a single packaging module. After each reel of connectors is packaged, the machine must be stopped to change the carrier tape. The material change process takes up a lot of production time, the equipment cannot run continuously, the utilization rate is greatly reduced, and the overall production capacity of the production line is seriously affected.

[0006] 4. Traditional equipment has structural limitations, only enabling automated detection of connector dimensions. It cannot perform comprehensive inspection of the entire product's end face and sides. Multiple surfaces are obscured by tooling, making machine vision inspection impossible. Therefore, appearance defect detection relies entirely on manual visual inspection. Manual inspection is prone to fatigue and subjectivity, easily leading to missed or false positives, resulting in a high risk of defective products leaving the factory. Furthermore, fixed-position manual inspection significantly increases labor costs for businesses.

[0007] In summary, existing connector testing and packaging equipment suffers from defects such as easy scratching of products, low operating efficiency, inability to produce continuously, low level of intelligence in appearance inspection, and poor quality control. There is an urgent need to develop an automatic connector testing and packaging machine that can achieve damage-free transfer, parallel testing, uninterrupted packaging, and fully automated appearance inspection. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic connector inspection and packaging machine and its working method. This solution addresses the problems of product scratches during transport, low efficiency due to sequential processes, downtime for packaging and tape replacement, missed inspections during manual appearance inspection, and high labor costs associated with traditional equipment. The invention achieves undamaged connector transport, parallel and efficient inspection, uninterrupted continuous packaging, and fully automated all-round appearance inspection, thereby improving product quality and equipment capacity.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0013] At least one module in each module is provided with a clamping and positioning assembly for flexibly clamping and positioning the connector. The clamping and positioning assembly includes a clamping bracket, an opening cylinder, an opening clamping component, a support base, a clamping block, and an alignment motor.

[0014] The clamping cylinder is fixedly mounted on one end of the clamping bracket. The clamping component is fixedly connected to the output end of the clamping cylinder. The alignment motor is fixedly mounted on the end of the clamping bracket away from the clamping cylinder. The support base is fixedly mounted on the output end of the alignment motor. The clamping blocks are slidably mounted in the support base and two are symmetrically arranged. Each clamping block is provided with an elastic element.

[0015] Furthermore, the feeding module includes a tray conveying mechanism for feeding connectors onto trays and a reciprocating transfer mechanism for precisely transferring connectors one by one.

[0016] The dimension inspection module includes a GT inspection mechanism for inspecting the geometric tolerances of the connector and a PIN gauge inspection mechanism for inspecting the dimensional accuracy of the connector pins.

[0017] The attitude adjustment module includes multiple attitude adjustment stations arranged along the connector conveying direction. Some attitude adjustment stations are equipped with a rotation mechanism for adjusting the horizontal angle of the connector, while the remaining attitude adjustment stations are equipped with a flipping mechanism for adjusting the front and back end faces of the connector.

[0019] The rack is also equipped with a rear barcode scanning mechanism, located downstream of the sampling module, for information verification after the entire inspection process is completed.

[0020] Furthermore, the front scanning mechanism is also equipped with a dust suction hood and a dust suction cylinder. The dust suction hood is slidably mounted on the clamping bracket and is used to clean residual impurities from the coding process on the connector. The dust suction cylinder is fixedly mounted and is connected to the dust suction hood in a transmission manner, and is used to drive the dust suction hood to slide back and forth.

[0021] Furthermore, the electrical testing module includes an electrical testing bracket and a rotation component and a pressure testing component disposed on the electrical testing bracket;

[0022] The indexing assembly includes an indexing motor and a rotating component connected to the output end of the indexing motor. One end of the rotating component is provided with a locking component, and the lower end of the locking component is connected to a locking cylinder for driving its lifting and lowering.

[0023] The pressure testing assembly includes a pressure rod, a cam block, an upper pressure testing cylinder, an upper pressure testing component, a lower pressure testing cylinder, and a lower pressure testing component. The pressure rod is rotatably mounted on the electrical testing bracket, the cam block is slidably mounted on the electrical testing bracket and its upper end abuts against the pressure rod, the output end of the upper pressure testing cylinder is connected to the cam block, and the lower pressure testing cylinder is fixed to the electrical testing bracket and its output end is fixedly connected to the lower pressure testing component.

[0024] Furthermore, the GT testing mechanism includes a GT testing frame, a GT tester, a clamping assembly, and a reciprocating moving assembly;

[0025] The GT tester is located at the output end of the reciprocating moving component and is positioned opposite to the clamping component; the clamping component includes positioning blocks symmetrically arranged on the GT testing frame, clamping blocks slidably arranged between the positioning blocks, a release component for loosening the clamping blocks, and a release cylinder for driving the release component to move.

[0026] The reciprocating moving assembly includes a support plate, a guide rail slider pair, an eccentric wheel, and a reciprocating motor. The GT tester is fixed on the support plate, and the support plate is slidably mounted on the GT test frame via the guide rail slider pair. The eccentric wheel is driven by the support plate, and the reciprocating motor is driven by the eccentric wheel.

[0027] Furthermore, the appearance inspection module includes multiple sets of CCD inspection mechanisms arranged in stages along the connector conveying path. The multiple sets of CCD inspection mechanisms are alternately arranged with the rotation mechanism and the flipping mechanism in the attitude adjustment module. The CCD inspection mechanism inspects the side after the connector is adjusted to a horizontal angle by the rotation mechanism, and inspects the front and back sides after the end face is flipped by the flipping mechanism.

[0028] Furthermore, the defective product sorting module includes a transfer box assembly and a support assembly disposed above the transfer box assembly;

[0029] The box transfer assembly includes a box transfer frame, a box transfer motor, a synchronous pulley pair, a support plate, a material box, and a guide rail slider pair; the box transfer motor is fixed to the box transfer frame, the synchronous pulley pair is connected to the output end of the box transfer motor, the support plate is fixed to the output end of the synchronous pulley pair, and multiple material boxes for classifying and storing defective products are arranged on the support plate; the bottom of the support plate is slidably engaged with the box transfer frame through the guide rail slider pair.

[0030] The bearing assembly includes a slide cylinder, a support plate, a support seat, a movable clamp, an insert block, and a release cylinder; the slide cylinder is fixed to the transfer box frame, the support plate is connected to the output end of the slide cylinder, the support seat is fixed to the support plate, the movable clamp is slidably disposed on the support seat, the insert block is used to push open the movable clamp, and the release cylinder is drivenly connected to the insert block.

[0031] The bearing component can switch its working state by extending and retracting the slide cylinder. It is only used to receive and transport qualified connectors. When defective products are transported by the transfer module, the bearing component retracts and does not receive them. The defective products fall directly into the material box to complete the automatic sorting.

[0032] Furthermore, the packaging module is a dual-carrier packaging device, which includes a feeding mechanism, two symmetrically arranged packaging mechanisms, and a dispensing mechanism; the two packaging mechanisms are respectively located at both ends of the feeding mechanism, and the dispensing mechanism is mounted above the two packaging mechanisms to complete the automated carrier packaging of qualified products.

[0033] A method for operating an automatic connector inspection and packaging machine includes the following steps:

[0034] S1. The connector is transported by the material tray conveying mechanism of the feeding module, and the connector is accurately moved to the marking station for positioning by the reciprocating transfer mechanism.

[0035] S2. Using a laser engraving machine in conjunction with the positioning and bearing function of the indexing turntable, laser marking is performed on the surface of the connector to complete the unique identification of the connector;

[0036] S3. The clamping and positioning components of the front-mounted scanning mechanism accurately clamp and align the coded connector, the code reader reads the code information of the connector, and at the same time the vacuum cylinder drives the vacuum cover to slide to clean up residual dust and impurities after coding.

[0037] S4. The connector is transferred to the electrical testing module, where the connector posture is adjusted and locked in place by the indexing component, and the electrical parameters of the connector are tested in conjunction with the pressure testing component. Then the connector is transferred to the GT testing mechanism, where the reciprocating moving component drives the GT tester to move back and forth, and the clamping component clamps and positions the connector to complete the geometric tolerance test of the connector.

[0038] S5. Adjust the horizontal orientation of the connector through the rotation mechanism, and complete the appearance dimension inspection of the left and right sides with the help of two sets of CCD detection mechanisms; then check the pin accuracy of the connector through the pin gauge detection mechanism, and after a second horizontal adjustment, complete the appearance dimension inspection of the top surface with the help of a set of CCD detection mechanisms.

[0039] S6. The connector is flipped in both directions by a flipping mechanism. After the bottom surface is inspected by a set of CCD inspection mechanisms, the connector is flipped again by another flipping mechanism. Then, the connector is inspected in all directions by three sets of CCD inspection mechanisms arranged in stages.

[0040] S7. Connectors are transferred to the sorting station. The transfer module continuously transports the connectors. Connectors that pass inspection are received by the extended support component and continue to be conveyed. When a connector that fails inspection passes by, the transfer module releases the connector, the support component retracts to an unloaded state and does not receive the connector. Defective products fall directly into the material box during the transfer process. At the same time, the material box switching component automatically switches the material box to achieve classified storage of defective products. The sampling inspection module randomly samples the connectors that pass inspection to complete the verification operation.

[0041] S8. The qualified connectors are scanned a second time by the rear scanning mechanism to verify the connector's full-process testing information. Finally, the connectors are automatically packaged and unpacked by the feeding mechanism and discharging mechanism of the dual carrier tape packaging device in conjunction with the packaging mechanisms at both ends.

[0042] Compared with the prior art, the present invention has the following significant advantages:

[0043] 1. This invention abandons the traditional rigid clamping and transfer method and adopts a flexible clamping and positioning component. The product transfer is completed through flexible opening and closing clamping and no rigid support contact, which completely avoids friction and scratches between materials and tooling and eliminates secondary damage to products. At the same time, the fully automated inspection replaces manual inspection, eliminating the problems of missed inspection and false inspection due to human fatigue. It improves the overall quality of products from the two dimensions of transfer and inspection and prevents defective products from flowing out.

[0044] 2. This invention innovatively adopts an alternating layout structure of posture adjustment station and appearance inspection station, which allows the time-consuming size and appearance inspection process and material handling process to be carried out in parallel, changing the traditional serial operation mode, eliminating station waiting time, greatly shortening the processing cycle of a single product, and significantly improving the overall operating efficiency of the equipment.

[0045] 3. This invention adopts a dual-carrier belt and dual-symmetrical packaging module structure. The two packaging mechanisms can work alternately on the left and right. After packaging at one end is completed, there is no need to stop the machine. The other end module can be switched directly to work and the carrier belt change operation can be completed simultaneously. This completely solves the problem of stopping to change materials in traditional single-line packaging. The equipment can run continuously for 24 hours, which greatly improves the machine utilization rate and the overall production line capacity.

[0046] 4. This invention uses a rotating mechanism and a flipping mechanism to adjust the orientation of the connector from multiple angles and on multiple end faces. Combined with a multi-group, step-by-step CCD inspection mechanism, it can achieve all-round exposure inspection of the left and right sides, top, bottom, front and back sides of the connector. The product is unobstructed and there are no blind spots in the inspection. It completely replaces the traditional manual appearance inspection process, reduces the cost of fixed-position manual labor, and at the same time, the machine vision inspection has higher accuracy and stronger stability, completely eliminating the risk of leakage due to manual inspection.

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] like Figures 1 to 11As shown, this embodiment provides an automatic connector inspection and packaging machine, including a frame 1, and a feeding module 10, an identification module 20, an electrical testing module 30, a size detection module 40, an appearance inspection module 50, a posture adjustment module 60, a defective product sorting module 70, a sampling inspection module 80, and a packaging module 90 arranged on the frame 1 along the connector conveying direction, so as to realize automatic full inspection of connector appearance and size, and can automatically package them into trays.

[0063] The feeding module 10 is used to move the connector to the predetermined marked starting position; the marking module 20 is used to mark and identify the connector with batch number; the electrical testing module 30 is used to test the electrical performance of the connector; the size inspection module 40 is used to inspect the size of the connector; the appearance inspection module 50 is used to inspect all the appearance surfaces of the connector; the posture adjustment module 60 is used to rotate the connector at multiple angles to perform corresponding functional tests; the defective product sorting module 70 is used to screen and remove unqualified products; the sampling inspection module 80 is used to perform a second quality inspection on the connector; and the packaging module 90 is used to package the connector.

[0064] The rack 1 is also equipped with a transfer module 2 for transferring connectors between modules and a control system for controlling the collaborative operation of the modules. The control system includes a control device 3 and a display device 4. The control device 3 is used to coordinate the automated workflow of the modules, and the display device 4 is used for setting equipment parameters and real-time monitoring of operating status.

[0065] At least one module in each module is provided with a clamping and positioning component 222 for flexibly clamping and positioning the connector.

[0066] The frame 1 serves as the basic support structure, providing a stable installation platform for various functional modules and devices. Preferably, it is made of high-strength metal materials to ensure the rigidity and stability of the equipment during long-term operation.

[0067] The transfer module 2 is suspended above each module and automatically transfers the connectors by reciprocating between adjacent workstations. The transfer module 2 specifically includes a transfer bracket and X-axis linear motion components, Y-axis linear motion components, a movable carrier plate, and pneumatic grippers mounted on the transfer bracket. The Y-axis linear motion component is mounted on the movable end of the X-axis linear motion component, and the movable carrier plate is mounted on the movable end of the Y-axis linear motion component. Multiple pneumatic grippers are evenly spaced on the movable carrier plate. In this embodiment, the transfer module 2 has three sections in the connector conveying direction, and each transfer module 2 has 6-7 pneumatic grippers to avoid excessive load on the same movable carrier plate, which would affect transfer accuracy.

[0068] The control device 3 coordinates the entire equipment process flow and integrates a PLC controller. It can monitor the operating status of each module in real time and send instructions to the transfer module 2 according to a preset program, thereby achieving automated flow of connectors on the production line. For example, after a connector completes electrical performance testing, the control device 3 immediately triggers the transfer module 2 to transfer it to the dimensional inspection module 40, while simultaneously scheduling the next connector to be inspected to enter the electrical testing station, thus maximizing equipment utilization and production efficiency. The control device 3 includes a control box externally mounted on the rack 1 for controlling equipment operation and shutdown. The display device 4 is installed at the rear end of each functional module on the rack 1 for parameter setting and status monitoring.

[0069] The feeding module 10, marking module 20, electrical testing module 30, dimensional inspection module 40, appearance inspection module 50, posture adjustment module 60, defective product sorting module 70, sampling inspection module 80, and packaging module 90, arranged along the connector conveying direction, are used to sequentially complete the processes of feeding, marking, electrical performance testing, dimensional inspection, visual appearance inspection, posture adjustment, defective product sorting, sampling re-inspection, and finished product packaging for the connectors, covering the entire post-production processing of the connectors. The functional modules are linearly distributed on the frame 1 according to the connector processing flow, forming an efficient and compact production line.

[0070] The feeding module 10 includes a tray conveying mechanism 11 and a reciprocating transfer mechanism 12, which are used to remove connectors one by one from the tray and transport them to the subsequent workstation. The tray conveying mechanism 11 is used to realize the tray feeding of connectors, and the reciprocating transfer mechanism 12 is used to accurately pick up and move the connectors one by one, ensuring feeding accuracy and continuity. The two work together to achieve efficient and accurate feeding operation.

[0071] The tray conveying mechanism 11 is driven by a stepper motor, which can precisely control the feed speed of the tray according to the production rhythm, ensuring that the connectors do not accumulate or jam during the conveying process. In this embodiment, a double tray is used for parallel conveying to improve the feeding efficiency.

[0072] The reciprocating transfer mechanism 12 includes a linear module, a lifting cylinder, and grippers, used to accurately remove connectors from the tray and transfer them to the marking station of the marking module 20. To improve positioning accuracy, the reciprocating transfer mechanism 12 is equipped with a high-resolution encoder and a vision positioning system, enabling precise displacement of connectors within milliseconds. This design not only improves loading efficiency but also lays a solid foundation for the smooth operation of subsequent processes.

[0073] The identification module 20 includes a coding mechanism 21, a front-end scanning mechanism 22, and a rear-end scanning mechanism 23 mounted on the frame 1, all of which together perform the functions of information management and traceability. The front-end scanning mechanism 22 is located downstream of the coding station and works in conjunction with it to input information after coding is completed. The rear-end scanning mechanism 23 is located downstream of the sampling inspection module 80 and is used to verify the information after the entire process inspection.

[0074] The marking mechanism 21 includes a laser engraving machine 211 and an indexing turntable 212 positioned opposite the laser engraving machine 211 for carrying and positioning the connector. The laser engraving machine 211 laser engraves permanent markings on the connector surface, such as product serial numbers, production dates, and batch information. The indexing turntable 212 has four positioning stations spaced apart for carrying and positioning the connector. The left and right positioning stations are used for receiving and moving, respectively, while the front and rear positioning stations are used for processing and buffering, respectively. The turntable rotates precisely in four positions via a stepper motor and is locked in place by a locking assembly to ensure high-precision rotation and positioning.

[0075] The front-end scanning mechanism 22 includes a barcode reader 221 and a clamping and positioning component 222 that is positioned opposite to the barcode reader 221 for precise positioning of the connector. The clamping and positioning component 222 enables precise alignment and clamping of the material, ensuring scanning accuracy.

[0076] The clamping and positioning assembly 222 includes a clamping bracket 2221, an opening cylinder 2222, an opening member 2223, a support base 2224, clamping blocks 2225, and a positioning motor 2226. The opening cylinder 2222 is fixedly mounted at one end of the clamping bracket 2221. The opening member 2223 is fixedly connected to the output end of the opening cylinder 2222. The positioning motor 2226 is fixedly mounted at the end of the clamping bracket 2221 away from the clamping cylinder 2222. The support base 2224 is fixedly mounted at the output end of the positioning motor 2226. The clamping blocks 2225 are slidably mounted inside the support base 2224 and are symmetrically arranged in two. Each clamping block 2225 is provided with an elastic element.

[0077] A support is also provided on the clamping bracket 2221, located between the clamping cylinder 2222 and the support base 2224, to support the clamping member 2223 and the dust cover 2227 to slide on it, ensuring sliding accuracy. Each clamping block 2225 is provided with an elastic element, which can automatically and elastically reset and clamp the connector. By achieving a flexible clamping effect, when the connector needs to be inserted or removed, the clamping member 2223 simultaneously abuts against the two clamping blocks 2225 and compresses the elastic element to release the connector. In this embodiment, the elastic element is specifically a compression spring.

[0078] Meanwhile, the front scanning mechanism 22 is also equipped with a dust hood 2227 and a dust suction cylinder 2228. The dust hood 2227 is slidably mounted on the clamping bracket 2221 and is used to clean the coding residue on the connector to ensure the cleanliness of the work station and the clarity of the markings. The dust suction cylinder 2228 is fixedly mounted on the sliding bracket and is connected to the dust hood 2227 for driving the dust hood 2227 to slide back and forth.

[0079] The structure of the rear scanning mechanism 23 is the same as that of the front scanning mechanism 22, the difference being the installation position on the production line.

[0080] The electrical testing module 30 includes an electrical testing bracket 31 and a rotation component 32 and a pressure testing component 33 disposed on the electrical testing bracket 31.

[0081] The indexing assembly 32 includes an indexing motor 321 and a rotating component 322 connected to the output end of the indexing motor 321. A locking component 323 is provided at one end of the rotating component 322, and a locking cylinder 324 for driving its lifting and lowering is connected to the lower end of the locking component 323. The indexing motor 321 is vertically mounted at one end of the electrical testing bracket 31. Its output shaft is connected to the rotating component 322 via a coupling and an intermediate shaft. The rotating component 322 has two positioning stations for carrying connectors, used for electrical testing and loading / unloading, respectively. The indexing motor 321 drives the rotating component 322 to rotate intermittently by 180 degrees each time. After the rotating component 322 has indexed a tested connector, an untested connector enters the electrical testing station. The locking component 323 rises and embeds into the rotating component 322, completing the positioning and locking of the rotating component 322.

[0082] The pressure testing assembly 33 includes a pressure rod 331, a cam block 332, an upper pressure testing cylinder 333, an upper pressure testing component 334, a lower pressure testing cylinder 335, and a lower pressure testing component 336. The pressure rod 331 is rotatably mounted on the electrical testing bracket 31, the cam block 332 is slidably mounted on the electrical testing bracket 31 and its upper end abuts against the pressure rod 331, the output end of the upper pressure testing cylinder 333 is connected to the cam block 332, and the lower pressure testing cylinder 335 is fixed to the electrical testing bracket 31 and its output end is fixedly connected to the lower pressure testing component 336. The upper pressure testing cylinder 333 is horizontally installed, which drives the cam block 332 to move closer to or away from the rotating part 322; the pressure rod 331 is hinged to the electrical testing bracket 31 near its middle part, and the end away from the cam block 332 is used to clamp the connector for subsequent electrical testing; the upper pressure testing component 334 is fixedly installed at the lower end of the pressure rod 331 and moves together with the cam block 332, and after the pressure rod 331 is fixed, it approaches the terminal of the connector for electrical testing; the lower pressure testing cylinder 335 is vertically fixed to the electrical testing bracket 31, and the lower pressure testing component 336 rises under its drive to approach the other end of the terminal for synchronous electrical testing.

[0083] The indexing motor 321 drives the material to rotate precisely, and works with the locking cylinder 324 to lock and position the material. The pressure testing component 33 drives the upper pressure testing component 334 and the lower pressure testing component 336 to work together through the cam transmission structure, accurately completing the detection of electrical parameters such as connector continuity and withstand voltage, with high detection stability.

[0084] The size detection module 40 includes a GT detection mechanism 41 and a PIN gauge detection mechanism 42.

[0085] GT testing mechanism 41 includes GT testing frame 411, GT tester 412, clamping assembly 413 and reciprocating moving assembly 414;

[0086] The GT tester 412 is located at the output end of the reciprocating moving assembly 414 and is positioned opposite to the clamping assembly 413. The clamping assembly 413 includes positioning blocks 4131 symmetrically arranged on the GT testing frame 411, clamping blocks 4132 slidably arranged between the positioning blocks 4131, a release element 4134 for releasing the clamping blocks 4132, and a release cylinder 4135 for driving the release element 4134 to move. The release cylinder 4135 is vertically installed below the GT testing frame 411, and its rod end is fixedly connected to the release element 4134. Two clamping blocks 4132 are symmetrically arranged, and each clamping block 4132 is provided with a spring, so that the clamping block 4132 automatically resets and clamps the connector. When the release element 4134 rises, it presses against the two clamping blocks 4132 and compresses the spring, so that the connector can be inserted or removed. Furthermore, the GT testing mechanism 41 also includes a secondary fixing component, which is set relative to the GT tester 412 for fixing the connector from the top. It includes a cylinder and a fixing head fixed to the cylinder rod end. After the connector is clamped from the side by the clamping block 4132, the cylinder drives the fixing head to extend from the top of the connector for secondary fixing, so that the connector is more securely fixed during the testing process, ensuring the accuracy of geometric tolerance testing.

[0087] The reciprocating moving assembly 414 includes a support plate 4141, a guide rail slider pair 4142, an eccentric wheel 4143, and a reciprocating motor 4144. The GT tester 412 is fixed on the support plate 4141. The support plate 4141 is slidably mounted on the GT testing frame 411 via the guide rail slider pair 4142. The eccentric wheel 4143 is in a driving engagement with the support plate 4141, that is, the outer contour surface of the eccentric wheel 4143 contacts and engages with one end face of the support plate 4141. The reciprocating motor 4144 is drivingly connected to the eccentric wheel 4143. A probe is fixedly installed at the end of the GT tester 412. The probe can be moved into the connector to complete the geometric tolerance test. In this embodiment, two sets of GT testers 412 are installed side by side on the GT testing frame 411. Each GT tester 412 is equipped with different types of probes, which are used to detect whether the distance from the outer conductor to the terminal and the distance from the outer shell end face to the outer conductor end face meet the tolerance requirements.

[0088] The GT testing mechanism 41 drives the tester to move back and forth via a reciprocating motor 4144 and an eccentric wheel 4143, adapting to material testing at different positions and completing the overall geometric tolerance testing of the connector; the PIN gauge testing mechanism 42 independently completes the dimensional accuracy testing of the connector PIN pins, achieving comprehensive dimensional parameter testing.

[0089] The PIN gauge inspection mechanism 42 includes an inspection frame, a support mounted thereon, and a through-beam photoelectric sensor. The support supports the connector, and the through-beam photoelectric sensor consists of an independent transmitter and a receiver, with the light beam shooting in a straight line. When the connector's PIN passes through the light path, it blocks the light beam, and the receiver outputs a status change signal to determine whether the PIN is present, whether the size is out of tolerance, or whether the position is off-target.

[0090] The attitude adjustment module 60 includes multiple attitude adjustment stations arranged along the connector conveying direction. Some attitude adjustment stations are equipped with a rotation mechanism 61 for adjusting the horizontal angle of the connector, and the remaining attitude adjustment stations are equipped with a flipping mechanism 62 for adjusting the front and back end faces of the connector.

[0091] The rotating mechanism 61 includes a rotating bracket, a motor fixed to the rotating bracket, a bearing seat fixed to the motor, positioning plates and loosening plates slidably mounted on the rotating bracket at both ends of the bearing seat, and drive cylinders mounted on the positioning plates and loosening plates respectively. Two symmetrical elastic clamping members slide on the bearing seat. After the motor rotates to the correct position, the positioning plates are extended by the cylinders for positioning, and the loosening plates are compressed by the cylinders to move the elastic clamping members into the connector.

[0092] The flipping mechanism 62 includes a flipping bracket, a flipping motor mounted on the flipping bracket, a flipping head fixed to the output shaft of the flipping motor, a support mounted on the flipping bracket opposite to the flipping head, and a linear motion module that drives the flipping motor to move linearly. The support receives the connector and drives the flipping motor and its flipping head to move through the linear motion module. The flipping head gradually inserts into the connector's insertion cavity. After reaching the insertion position, the flipping motor rotates 180 degrees and then slowly retracts to reset, completing the connector flipping.

[0093] The appearance inspection module 50 includes multiple sets of CCD inspection mechanisms 51 arranged in stages along the connector conveying path. The multiple sets of CCD inspection mechanisms 51 are alternately arranged with the rotation mechanism 61 and the flipping mechanism 62 in the attitude adjustment module 60. The CCD inspection mechanism 51 inspects the side after the connector is adjusted to a horizontal angle by the rotation mechanism 61, and inspects the front and back after the end face is flipped by the flipping mechanism 62. While the transfer module 2 is transporting materials, the attitude adjustment and appearance inspection are completed simultaneously, realizing parallel operation of the process and greatly reducing the inspection time.

[0094] The CCD inspection agency 51 uses a high-resolution CCD camera to capture images of the connector surface from multiple angles and then analyzes the acquired images using image processing algorithms to identify surface defects, scratches, dimensional deviations, and other problems.

[0095] In this embodiment, the production line is equipped with 7 sets of CCD inspection mechanisms 51, which are used to inspect the appearance defects of the six sides of the connector. Among them, the front face of the connector, i.e. the insertion face, has more inspection elements, so in order to speed up the inspection, two CCD inspection mechanisms 51 are set up for inspection. The CCD inspection mechanisms 51 for inspecting the four sides of the connector are horizontally set, while the CCD inspection mechanisms 51 for inspecting the top and bottom faces are vertically set.

[0096] In this embodiment, the arrangement order of the 7 sets of CCD detection mechanisms 51, rotation mechanism 61, and flipping mechanism 62 is as follows: first rotation mechanism, first CCD detection mechanism, second CCD detection mechanism, second rotation mechanism, third CCD detection mechanism, first flipping mechanism, fourth CCD detection mechanism, second flipping mechanism, fifth CCD detection mechanism, sixth CCD detection mechanism, and seventh CCD detection mechanism.

[0097] The CCD inspection mechanism 51 can inspect the left, right, front, back, and top surfaces after the material is rotated horizontally, and inspect the bottom surface after the material is flipped over, with no blind spots, thus achieving full-face appearance defect inspection.

[0098] The defective product sorting module 70 includes a transfer box assembly 71 and a carrier assembly 72 disposed above the transfer box assembly 71.

[0099] The box transfer assembly 71 includes a box transfer frame 711, a box transfer motor 712, a synchronous pulley pair 713, a support plate 714, a material box 715, and a guide rail slider pair 4142. The box transfer motor 712 is fixed to the box transfer frame 711, the synchronous pulley pair 713 is connected to the output end of the box transfer motor 712, the support plate 714 is fixed to the output end of the synchronous pulley pair 713, and multiple material boxes 715 for classifying and storing defective products are arranged on the support plate 714. The bottom of the support plate 714 is slidably engaged with the box transfer frame 711 through the guide rail slider pair 4142.

[0100] The bearing assembly 72 includes a slide cylinder 721, a support plate 722, a support seat 723, a movable clamp 724, an insert block 725, and a release cylinder 726. The slide cylinder 721 is fixed to the transfer box frame 711, the support plate 722 is connected to the output end of the slide cylinder 721, the support seat 723 is fixed to the support plate 722, the movable clamp 724 is slidably disposed on the support seat 723, the insert block 725 is used to push open the movable clamp 724, and the release cylinder 726 is connected to the insert block 725 in a transmission connection.

[0101] The transfer box assembly 71 drives the multi-material box 715 to switch via the transfer box motor 712 and the synchronous belt pulley pair 713, realizing the classification and storage of defective products; the bearing assembly 72 can switch working states by extending and retracting the slide cylinder 721. When good products are conveyed, the bearing plate 722 extends and receives the material through the movable clamp 724. The open clamp suspension transition method is adopted, with no hard contact, to avoid scratching the product.

[0102] The carrying component 72 can be extended and retracted by the slide cylinder 721 to switch working states. It is only used to receive and transport qualified connectors. When defective products are transported by the transfer module 2, the carrying component 72 retracts and does not receive them. The defective products fall directly into the material box 715 to complete automatic sorting. The sorting is accurate and without damage.

[0103] The specific sorting action is as follows: When the transfer module 2 transports the connector to the sorting station, the control device 3 issues a command based on the detection result. If it is a good product, the slide cylinder 721 extends, the movable clamp 724 is in a closed, ready-to-receive state, and the transfer module 2 places the connector into the movable clamp 724; if it is a defective product, the slide cylinder 721 remains retracted, and the release cylinder 726 drives the plug block 725 to push open the movable clamp 724, making the receiving position open. The transfer module 2 then triggers the release action, and the connector falls vertically into the material box 715 below under the action of gravity, without any hard collisions throughout the process.

[0104] The sampling inspection module 80 randomly samples qualified connectors along the conveying path, performing manual or equipment-based verification and re-inspection to further ensure product quality before shipment. The sampling inspection module 80 includes a sampling bracket, a linear motion module mounted on the sampling bracket, and a loading plate mounted on the output end of the linear motion module. The loading plate carries multiple connectors that have passed inspection. These connectors are moved to the edge of the frame 1 by the linear motion module for easy removal and sampling by the operator. Simultaneously, the loading plate retains a transfer station corresponding to the transfer module 2, ensuring that subsequent packaging is not affected.

[0105] To improve utilization rate, the packaging module 90 is a dual-carrier packaging device, which includes a feeding mechanism 91, two symmetrically arranged packaging mechanisms 92 and a discharging mechanism 93. The two packaging mechanisms 92 are respectively located at both ends of the feeding mechanism 91, and the discharging mechanism 93 is mounted above the two packaging mechanisms 92 to complete the automated carrier packaging of qualified products.

[0106] The feeding mechanism 91 includes a linear motion module and a support mounted on its output end, which is used to hold the connectors to be packaged. The feeding mechanism 91 is driven by a servo motor and can precisely control the feed speed of the carrier tape according to the packaging rhythm, ensuring that the connectors do not shift or jam during the packaging process.

[0107] The feeding mechanism 93 includes an X-axis linear motion module, a Y-axis linear motion module, and a suction cup. The Y-axis linear motion module is mounted on the output end of the X-axis linear motion module, and the suction cup is mounted on the output end of the Y-axis linear motion module. The connector on the support of the feeding mechanism 91 is picked up by moving the suction cup.

[0108] The packaging mechanism 92 includes a feeding tray, a receiving tray, a conveyor belt, and a heat sealing assembly. The feeding tray and receiving tray are installed at the beginning and end of the conveyor belt, respectively, and the heat sealing assembly is installed above the conveyor belt near the middle. The empty belt flows out from the feeding tray, is conveyed by the conveyor belt, and the suction cups pick up the connectors one by one and place them into each space of the carrier belt. After being sealed by the heat sealing assembly, it is wound up by the receiving tray.

[0109] Preferably, the packaging mechanism 92 adds a roller assembly to the conveyor belt to flatten the carrier belt and avoid poor packaging due to wrinkles.

[0110] The two packaging mechanisms 92 can operate alternately, achieving seamless switching without stopping the machine. The specific control logic is as follows: the control device 3 monitors the remaining carrier tape of both packaging mechanisms 92 in real time; when the carrier tape of the first packaging mechanism 92 is about to run out, the feeding mechanism 91 guides qualified products to the second packaging mechanism 92 for continued packaging. The first packaging mechanism 92 stops after completing the sealing of the current carrier tape, and a new carrier tape is manually replaced; once the first group is ready and the second group is about to run out, it switches back to the first group. This cycle repeats, eliminating the need for the equipment to stop for material replacement, achieving 24-hour uninterrupted automated carrier tape packaging, greatly improving equipment uptime and production capacity.

[0111] This embodiment also provides a method for operating an automatic connector inspection and packaging machine, including the following steps:

[0112] S1. The connector is transported by the tray conveying mechanism 11 of the feeding module 10, and the connector is accurately moved to the marking station for positioning in conjunction with the reciprocating transfer mechanism 12.

[0113] S2. Using the positioning and bearing function of the laser engraving machine 211 and the indexing turntable 212, laser marking is performed on the surface of the connector to complete the unique identification of the connector.

[0114] S3. The clamping and positioning component 222 of the front scanning mechanism 22 accurately clamps and aligns the coded connector, the code reader 221 reads the code information of the connector, and at the same time the vacuum cylinder 2228 drives the vacuum cover 2227 to slide to clean up the residual dust and impurities after coding.

[0115] S4. The connector is transferred to the electrical testing module 30. The connector posture is adjusted and locked in place by the indexing component 32. The electrical parameters of the connector are tested in conjunction with the pressure testing component 33. Then the connector is transferred to the GT testing mechanism 41. The reciprocating moving component 414 drives the GT tester 412 to move back and forth. The clamping component 413 clamps and positions the connector to complete the geometric tolerance test of the connector.

[0116] S5. Adjust the horizontal orientation of the connector by rotating mechanism 61, and complete the appearance dimension inspection of the left and right sides with the help of two sets of CCD detection mechanisms 51; then check the pin accuracy of the connector by PIN gauge detection mechanism 42, and after a second horizontal adjustment, complete the appearance dimension inspection of the top surface with the help of a set of CCD detection mechanisms 51.

[0117] S6. The connector is flipped in both directions by the flipping mechanism 62. After the appearance and size of the bottom surface are inspected by a set of CCD detection mechanisms 51, the connector is flipped again by another flipping mechanism 62. Then, the appearance and size of the front and rear sides of the connector are inspected in all directions by the three sets of CCD detection mechanisms 51 arranged in stages.

[0118] S7. Connectors are transferred to the sorting station. The transfer module 2 continuously transports the connectors. Connectors that pass inspection are received by the extended support component 72 and continue to be conveyed. When a connector that fails inspection passes by, the transfer module 2 releases the connector, the support component 72 retracts to an unloaded state and does not receive the connector. Defective products fall directly into the material box 715 during the transfer process. At the same time, the transfer box component 71 automatically switches the material box 715 to achieve classified storage of defective products. The sampling inspection module 80 randomly samples the connectors that pass inspection to complete the verification operation.

[0119] S8. The qualified connector is scanned a second time by the rear scanning mechanism 23 to verify the connector's full-process testing information. Finally, the connector is automatically packaged and discharged by the feeding mechanism 91 and the unloading mechanism 93 of the dual carrier tape packaging device in conjunction with the packaging mechanisms 92 at both ends.

[0120] In step S3, the alignment motor 2226 drives the support base 2224 and the clamping block 2225 to complete the alignment and posture adjustment of the connector, and the clamping cylinder 2222 drives the clamping component 2223 to move, so as to realize the automatic clamping and loosening of the connector and ensure the scanning positioning accuracy.

[0121] In step S4, when the electrical testing module 30 is operating, the indexing motor 321 drives the rotating component 322 to rotate the connector, and the locking cylinder 324 drives the locking component 323 to lock and fix the connector; the upper pressure testing cylinder 333 drives the cam block 332 to slide and abut against the pressure rod 331 to complete the upper positioning, and the lower pressure testing cylinder 335 drives the lower pressure testing component 336 to move, thus completing the detection of the connector's electrical withstand voltage and continuity parameters.

[0122] In step S4, when the GT testing mechanism 41 is working, the release cylinder 4135 drives the release component 4134 to push open the clamping block 4132, realizing the quick pick-up and placement of the connector; the reciprocating motor 4144 drives the eccentric wheel 4143 to rotate, which drives the bearing plate 4141 and the GT tester 412 to move smoothly back and forth along the guide rail slider pair 4142, adapting to the testing requirements of connectors in different positions.

[0123] In step S7, when the defective product sorting module 70 is operating, the slide cylinder 721 drives the support plate 722 to extend and retract to switch working states; when the connector is qualified, the support plate 722 extends to receive the good product through the movable clamp 724 and completes the transfer and conveying; when the connector is unqualified, the support plate 722 retracts, the transfer module 2 releases the connector, and the defective product, without the support structure, falls directly into the material box 715; the transfer box motor 712 drives the support plate 714 to move through the synchronous belt pulley pair 713, realizing the automatic switching of multiple material boxes 715 and completing the classification and storage of different types of defective products.

[0124] In summary, this invention achieves fully automated operation of connectors from detection to packaging through integrated functional module layout, interleaved posture adjustment mechanism, flexible positioning and clamping bearing component 72, parallel operation detection strategy, and dual-carrier non-stop packaging device. It effectively solves the problems of easy product scratching, low detection efficiency, downtime for tape replacement, and easy omissions in manual appearance inspection in the prior art, and significantly improves product quality and production efficiency.

[0125] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
