The production of PCBA modules may be through a number of processes, each or most of which, upon completion, scans the two-dimensional code on the module for entry into the management system.

In the related scheme, the PCBA module relies on manual work for final code scanning detection. The sign indicating number detection is swept to the PCBA module one by one to the manual work, and detection efficiency is low, and the cost of labor is very high moreover.

The preferred embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the present specification.

Referring to fig. 1 and 2, the electronic module code scanning detector comprises a frame 1, a first conveying mechanism 2, a baffle 3, a sensing device 4, a centering mechanism 5, a carrying mechanism 6, a code scanning mechanism 7, a second conveying mechanism 8 and a management system, and is used for scanning and detecting the electronic module code scanning, so that whether each item of production data of the electronic module is accurate or not is judged, and further the next step of work is facilitated to prepare.

The electronic module can be a PCBA module obtained by SMT loading of a PCB blank board or the whole process of a DIP plug-in.

The electronic modules may be a plurality of modules which are placed together on the tray 9 for inspection and boxing. The tray 9 may be a blister tray.

The first conveying mechanism 2, the baffle 3, the centering mechanism 5, the carrying mechanism 6, the code scanning mechanism 7 and the second conveying mechanism 8 are all arranged on the rack 1. The first conveying mechanism 2 is positioned at the front end of the rack 1 and used for conveying a tray 9 which is conveyed from the front and contains the electronic modules to be detected to a first position. The centering mechanism 5 carries out comparatively accurate counterpoint adjustment to the position of tray 9, makes tray 9 be located the accurate position that corresponds with the first position, and the transport mechanism 6 of being convenient for is accurate snatchs tray 9. The carrying mechanism 6 grips the tray 9 and transfers the tray 9 from the first position to the second position. The code scanning mechanism 7 scans the electronic modules in the tray 9 to recognize code information of each electronic module, and sends the code information to the management system. The management system judges whether the corresponding module is correct or not according to the code information, and if the judgment result is correct, the corresponding module passes the detection, so that the automatic detection function of the electronic module is realized, the detection efficiency is improved, and the labor cost is reduced.

The frame 1 is a main body frame for installing and fixing other parts of the electronic module code scanning detector.

The bottom of the frame 1 can be provided with castors so as to be directly pushed when the transfer is needed, thus being convenient for arrangement in a factory production line. The outside of frame 1 can set up the sheet metal shell, and is not only pleasing to the eye, can also play the protection to inside other parts and prevent that external dust from getting into.

Referring to fig. 3 and 4, the first conveying mechanism 2 includes a first conveyor belt 21, a first driving pulley 22, a first driven pulley 23, and a first driving motor 24.

The first driving pulley 22 and the first driven pulley 23 are rotatably mounted on the frame 1 via different rotating shafts, respectively. The axial direction of the first driving pulley 22 and the axial direction of the first driven pulley 23 are parallel to each other, and in the use state, the plane on which the axial direction of the first driving pulley 22 and the axial direction of the first driven pulley 23 are located is substantially horizontal.

The first belt 21 is sleeved on a first driving pulley 22 and a first driven pulley 23. The distance between the first driving pulley 22 and the first driven pulley 23 tensions the first conveyor belt 21 to facilitate the transport of the material.

The first drive motor 24 is fixed to the frame 1.

A synchronizing wheel is fixed on an output shaft of the first driving motor 24, a rotating shaft provided with the first driving belt wheel 22 is also fixed with a synchronizing wheel, and the two synchronizing wheels are in transmission connection through a matched synchronous belt. Therefore, the first driving motor 24 can drive the rotating shaft mounted with the first driving pulley 22 to rotate, and further drive the first conveyor belt 21 to rotate around the first driving pulley 22 and the first driven pulley 23 through the first driving pulley 22, so as to realize the material conveying function.

Two first conveyor belts 21, two first driving pulleys 22, and two first driven pulleys 23 may be provided. Each first belt conveyor 21 is correspondingly arranged on one first driving pulley 22 and one first driven pulley 23, so that the two first belt conveyors 21 form a structure parallel to each other in the left-right direction. When the tray 9 is conveyed, the left and right portions of the bottom of the tray 9 are supported on the left and right first conveyor belts 21, respectively, so that the conveyance is more stable.

The first position may be located at the end of the transport path of the first transport mechanism 2. In the present embodiment, the first position is on the first belt 21 near the first driving pulley 22.

The baffle 3 is fixed to the frame 1 at the rear edge of the first position. Thus, the tray 9 stops after contacting the shutter 3 as the first conveyor belt 21 moves backward, and the front-rear position of the stop of the tray 9 is exactly the same as the front-rear position of the first position.

With continued reference to fig. 2, the sensing device 4 is secured to the frame 1. The sensing device 4 is close to the barrier 3 and in front of the barrier 3. The sensing device 4 is used for sending a sensing signal when the tray 9 reaches a certain position range, and further controlling the first conveying mechanism 2 to stop running.

For example, the sensing device 4 may send a sensing signal when the tray 9 is about to reach the first position. After receiving the sensing signal, the control system delays for a preset time (for example, delays for 1 second to ensure that the tray 9 contacts the baffle 3), and then controls the first conveying mechanism 2 to stop operating.

In some embodiments, the sensing device 4 may be configured to send a sensing signal when the tray 9 contacts the baffle 3. And after receiving the induction signal, the control system immediately controls the first conveying mechanism 2 to stop running.

Referring to fig. 5, the centering mechanism 5 includes a third jaw 51, a fourth jaw 52, a fixed seat 53, and a jaw drive sub-mechanism 54.

The fixed seat 53 is fixed on the frame 1. The fixing base 53 is fixedly provided with a transverse guide 531 along the left-right direction.

The third jaw 51 and the fourth jaw 52 are both arranged on the transverse guide rail 531 in a manner of sliding left and right along the transverse guide rail 531. The third jaw 51 and the fourth jaw 52 are located on the left and right sides, respectively.

The jaw drive sub-mechanism 54 includes a third drive motor 541, a screw transmission part 542, and a reverse synchronization transmission part 543.

The reverse synchronous transmission part 543 is in transmission connection with the third jaw 51 and the fourth jaw 52. The reverse synchronous transmission unit 543 may synchronously move the third jaw 51 and the fourth jaw 52 closer to or farther from each other.

The reverse synchronization transmission member 543 includes a lever 5431, a first link 5432, and a second link 5433.

The lever 5431 is hinged to the fixed seat 53 through an intermediate portion thereof. Both ends of the lever 5431 are hinged to one end of the first link 5432 and one end of the second link 5433, respectively.

The end of the first link 5432 remote from the lever 5431 hinges the third jaw 51. The end of the second link 5433 remote from the lever 5431 is hinged to the fourth jaw 52. Thus, when the lever 5431 is turned around its hinge point with the fixed seat 53, the third jaw 51 and the fourth jaw 52 are synchronously close to or synchronously far away.

In some embodiments, the reverse synchronous driving unit 543 may also be a bidirectional screw structure, a bidirectional belt linear driving mechanism, etc.

The third driving motor 541 is connected to the third chuck 51 through the lead screw transmission member 542. The third driving motor 541 drives the third jaw 51 to move along the cross rail 531 through the screw transmission member 542. The third clamping jaw 51 drives the fourth clamping jaw 52 to synchronously approach the third clamping jaw 51 or synchronously move away from the third clamping jaw 51 through the reverse synchronous transmission part 543. Thus, when the third jaw 51 and the fourth jaw 52 are simultaneously brought close to each other, the positional accuracy of the tray 9 at the first position can be adjusted by pressing the left and right sides of the tray 9.

Referring to fig. 6, the carrying mechanism 6 includes a gripper sub mechanism 61, an elevator sub mechanism 62, an elevator guide 63, and a translation sub mechanism 64.

The gripper mechanism 61 includes a first jaw 611, a second jaw 612, and a gripping power device 613.

The clamping power device 613 may be a bidirectional air cylinder or other bidirectional driving device for driving the first clamping jaw 611 and the second clamping jaw 612 to approach each other, thereby clamping the tray 9.

For example, the clamping power device 613 adopts a bidirectional cylinder, and two piston rods in different directions of the bidirectional cylinder are respectively and fixedly connected with the first clamping jaw 611 and the second clamping jaw 612, so that when the two piston rods in different directions of the bidirectional cylinder are both retracted, the first clamping jaw 611 and the second clamping jaw 612 can be driven to approach each other to clamp the tray 9.

Suction cups 614 are fixedly arranged on the first clamping jaw 611 and the second clamping jaw 612 respectively. The suction cups 614 can be firmly attached to the sides of the tray 9. Thus, the tray 9 is prevented from slipping or overturning when the first and second holding

claws

611 and 612 grip the tray 9.

The gripper mechanism 61 is provided on the elevating guide 63 so as to be slidable up and down along the elevating guide 63 by means of a slide block. For example, when the clamping power device 613 is a bidirectional cylinder, the bidirectional cylinder may be fixed to a slide block, and the first clamping jaw 611 and the second clamping jaw 612 may be fixed to corresponding piston rods of the bidirectional cylinder.

The lift sub-mechanism 62 includes a lift driving motor 621 and a lead screw driving mechanism 622.

The lifting driving motor 621 is fixed on the top of the lifting guide rail 63 and is in transmission connection with the sliding block through a screw rod driving mechanism 622. Therefore, the lifting driving motor 621 can drive the sliding block to move up and down through the screw rod driving mechanism 622, and further drive the first clamping jaw 611 and the second clamping jaw 612 to move up and down, so as to achieve the purpose of lifting the clamped tray 9 from the first position to the second position.

The translation sub-mechanism 64 includes a slide 641, a slide 642, and a translation drive 643.

The slide rail 642 is fixed to the frame 1 in the front-rear direction. The slide 641 is disposed on the slide rail 642 to move back and forth along the slide rail 642. The lifting rail 63 is vertically fixed to the slider 641.

The translation driving device 643 may be specifically a screw motor structure, and is configured to drive the slide 641 to move back and forth along the slide rail 642. Accordingly, when the lifting rail 63 moves along with the slide 641, the gripper mechanism 61 can place the detected tray 9 at the third position for further processing.

Referring to fig. 7, the code scanning mechanism 7 includes a holder 71, a camera 72, a recognition device, a transmission device, and a light source 73.

The fixing frame 71 is fixed to the frame 1 and located above the carrying mechanism 6.

The camera 72 is fixed to the fixing frame 71 and is used for shooting a code image on the electronic module. The cameras 72 may be specifically provided in two or more numbers, so that the viewing range is ensured to cover all the electronic modules in the tray 9, and the imaging clarity can be improved.

The light source 73 is fixed on the fixing frame 71 and used for supplementing light for the camera 72 during shooting. The light source 73 may be disposed lower than the camera 72, i.e., closer to the tray 9, so as to improve the light supplement effect for the target object.

The light sources 73 may be disposed one on each of the front and rear sides corresponding to the second position, so that the brightness of the electronic module on the tray 9 is more uniform.

The light source 73 may be designed as an elongated light strip having a width corresponding to the width of the tray 9, so as to further improve the uniformity of illumination of the electronic modules on the tray 9.

The recognition device is electrically connected to the camera 72 to acquire a code image photographed by the camera 72 and recognize the code image as code information.

The sending device is in electric signal connection with the identification device, so that the code information identified by the identification device is sent to the management system, and the management system can conveniently judge whether the corresponding electronic module is correct or not according to the code information.

The management system may be an MES (manufacturing execution system), and production data of the electronic module corresponding to each code information is entered in advance in a database of the management system.

For example, in a PCBA module production line, a two-dimensional code is previously set on a module circuit board, and after each component is mounted, the two-dimensional code on the module is scanned, code information corresponding to the two-dimensional code is found in a database of a management system, and information about the mounting is added to the code information (e.g., XX component is mounted at XX time). Therefore, after the production of the PCBA module is finally completed, all production information corresponding to the PCBA module is recorded in the database of the management system.

In some embodiments, the management system may also be a subsystem belonging to the onboard control system of the code scanning detection machine of the electronic module.

After the management system acquires the code information sent by the code scanning mechanism 7, the management system searches the corresponding code information in the database and judges whether a problem exists. If no problem exists, a correct judgment result of the corresponding electronic module is obtained. If there is a problem, a judgment result that the corresponding electronic module is wrong is obtained.

For example, after the management system finds the corresponding code information in the database, the management system finds that the code information is recorded in the complete production process of the corresponding electronic module, all the elements are correctly installed, and all the indexes meet the standard requirements, so that the correct judgment result of the corresponding electronic module is obtained.

If the code information is found to lack a certain step or no record of a certain element is installed in the production process of the code information entry, the corresponding electronic module is a problem module, and then a judgment result that the corresponding electronic module is wrong is obtained.

If the corresponding code information cannot be found in the database, the corresponding electronic module is also indicated to be a problem module, and a judgment result that the corresponding electronic module is wrong is obtained.

After the management system obtains the judgment result that all the electronic modules in the currently detected tray 9 are correct, the management system controls the carrying mechanism 6 to transfer the currently detected tray 9 to the third position.

In the case that the management system is an MES system, the specific way of controlling the carrying mechanism 6 may be to control the carrying mechanism 6 to perform actions by sending a signal to the control system of the electronic module code scanning detector.

When the management system is one subsystem in the control system of the electronic module code scanning detector, the control system can directly control the carrying mechanism 6 to execute the operation.

In some embodiments, the management system may also directly send control commands to control the carrying mechanism 6 to perform relevant actions.

With continued reference to fig. 3 and 4, the second conveying mechanism 8 includes a second conveyor belt 81, a second driving pulley 82, a second driven pulley 83, and a second drive motor 84.

The second driving pulley 82 and the second driven pulley 83 are rotatably mounted on the frame 1 via different rotation shafts, respectively, behind the conveyance mechanism 6. The axial direction of the second driving pulley 82 and the axial direction of the second driven pulley 83 are parallel to each other, and in the use state, the plane on which the axial direction of the second driving pulley 82 and the axial direction of the second driven pulley 83 are located is substantially horizontal.

The second belt 81 is sleeved on the second driving pulley 82 and the second driven pulley 83. The distance between the second driving pulley 82 and the second driven pulley 83 tensions the second conveyor belt 81 for conveying the material.

The second drive motor 84 is fixed to the frame 1. The second driving motor 84 can drive the rotating shaft provided with the second driving pulley 82 to rotate through a transmission mechanism composed of a synchronous belt and a synchronous wheel, so as to drive the second driving pulley 82 to rotate, and further drive the second conveyor belt 81 to rotate around the second driving pulley 82 and the second driven pulley 83 through the second driving pulley 82, so as to realize the material conveying function.

Two second belts 81, two second driving pulleys 82, and two second driven pulleys 83 may be provided, respectively. Each of the second belts 81 is provided on one of the second driving pulleys 82 and one of the second driven pulleys 83, and the two second belts 81 are arranged in parallel in the left-right direction. When the tray 9 is conveyed, the left and right portions of the bottom of the tray 9 are supported on the left and right second conveyor belts 81, respectively, so that the conveyance is more stable.

The second position is located in the first section of the conveying path of the second conveyor 8. In this embodiment, the third position is on the second conveyor belt 81 near the second driven pulley 83, so that the tray 9 containing the electronic module passing the detection can be conveyed away from the third position for further processing under the driving of the second driving motor 84.

Referring to fig. 1 to 7, an operation process of the electronic module code scanning detector of the present application is as follows:

a plurality of PCBA modules are placed on the tray 9. A plurality of trays 9 on which PCBA modules are placed are stacked and placed in a dozen manner on the first conveyor belt 21 of the first conveyor mechanism 2. The first drive motor 24 drives the first conveyor belt 21 to rotate, and conveys the stacked and beaten tray 9 to the first position. After the sensing device 4 senses that the tray 9 reaches the first position, the control system controls the first conveying mechanism 2 to stop running.

The centering mechanism 5 positions the tray 9 more accurately in the first position by adjusting the positions of the third jaw 51 and the fourth jaw 52. The carrying mechanism 6 grips one of the trays 9 on the uppermost layer by the first and second

611 and 612, and lifts the tray 9 to the second position.

The code scanning mechanism 7 takes an image by its camera 72 containing an image of the codes on all the electronic modules on the tray 9. The tray 9 refers to the tray 9 conveyed to the second position by the conveying mechanism 6. The recognition means of the code scanning mechanism 7 recognizes the code information corresponding to each code image. The transmitting means of the code scanning mechanism 7 transmits all the code information recognized to the management system.

The management system compares the code information sent by the code scanning mechanism 7 with the code information stored in the database, and if the consistent code information exists or the code information which is consistent and meets the standard exists, the electronic module corresponding to the code information is judged to be correct. If all the electronic modules on the tray 9 are correct, the conveying mechanism 6 is controlled to transfer the tray 9 to the third position. If the electronic module on the tray 9 is incorrect, a corresponding signal is fed back to the code scanning mechanism 7, the code scanning mechanism 7 gives an alarm and displays the electronic module with the problem, and then manual processing is requested for solving the problem.

After the conveying mechanism 6 transfers the detected tray 9 to the third position, the second conveying mechanism 8 operates to transfer the tray 9 on the third position to the next station through the second conveyor belt 81, so as to be packaged in a centralized manner.
