As mentioned above, the conventional dispensing apparatus belongs to an offline operation mode, that is, the dispensing apparatus is a simple dispensing apparatus, and dispensing is completed by mechanical movement; the glue dispensing equipment has no data interaction relative to the front and the rear, or the data generation and transmission of the glue dispensing equipment are collected from time to time in the manual operation process, the generated data are intermittent and scattered, and the data have great limitation on production assistance; the quality of the glue is completely judged by human eyes, so that misjudgment or missing judgment is easily caused, bad flow is caused to the next procedure, the bad tracing is difficult, meanwhile, the judgment of the human eyes is easily influenced by external factors, the judgment standard also has individual difference and the like, and the quality of the traditional glue is unstable.
Different with traditional glue dispensing equipment, the glue dispensing equipment of this application can accomplish the former process quality automatically and detect and glue the quality management and control, can realize the bad screening of former way, can stop again that the glue dispensing process produces bad forward circulation down.
The application principle, the working process, the dispensing equipment and the method of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of basic components of a dispensing apparatus. As shown in fig. 1, the dispensing apparatus includes a controller (not shown), an apparatus stage 10, a dispensing nozzle 40, a driving device 20, a camera 30, and the like.
The equipment table 10 is a main component of the dispensing equipment, and the equipment table 10 is in contact with a placement surface (such as a ground surface, a table top or a marble table top) of the dispensing equipment, plays a main supporting role, and is also used for arranging other components thereon. The lower surface 102 of the equipment machine 10 contacts with the equipment placing surface, the material tray 70 can be arranged on the upper surface 101 of the equipment machine 10, and the material tray 70 containing the module to be dispensed is usually fixed by using a material tray fixing component.
The driving device 20 is disposed on the equipment platform 10 and can drive the dispensing nozzle 40 to move in the XY plane and in the Z-axis direction (details are not shown in fig. 1). The controller is in communication connection with the driving device 20 and the dispensing nozzle 40, and controls the driving device 20 to move the dispensing nozzle 40 to a proper position and controls the dispensing nozzle 40 to perform dispensing operation on the module.
The camera 30 is used for scanning the modules in the tray 70 before and after dispensing. The controller is in communication connection with the camera 30 and identifies good modules in the tray 70 according to the scanning data transmitted by the camera 30.
The screen 50 may also be used to display the product condition of the module to be dispensed. The screen 50 may display according to the specification of the tray 70, and the display positions correspond to those of the tray 70 one by one. As shown in fig. 1, two points a correspond to each other, and two points B correspond to each other. Before dispensing begins, the camera 30 captures OK/NG status (OK represents good and NG represents bad) of all the modules to be dispensed, and uploads the OK/NG status to the database of the data center, and the OK/NG status is displayed on the screen 50. After dispensing, the camera 30 shoots the OK/NG status of all dispensing modules again, and uploads the OK/NG status to the database again, and the OK/NG status is displayed on the screen 50. The screen 50 may be provided in a movable form to facilitate the operator to perform the relevant work by adjusting the orientation of the screen.
The operation of the dispensing device is explained below with reference to fig. 2 and 3.
Fig. 2 is a schematic diagram of a basic working flow of the dispensing apparatus, and fig. 3 is a schematic diagram of the full-automatic dispensing apparatus. After the material tray 70 is loaded, the camera 30 is firstly used for scanning the identification codes, such as the two-dimensional codes, of the modules in the material tray 70, and the controller calls the database of the tracing data center according to the two-dimensional codes, so that the previous procedure (previous information tracing) is linked, the data of the previous procedure is acquired, and the previous procedure is identified and controlled to be bad. Previous failures include, but are not limited to, the following (all of which would be judged to be NG products):
(1) The dispenser fails to acquire the module two-dimensional code;
(2) Acquiring the previous information through the two-dimensional code, wherein the previous information fails or is null;
(3) And displaying the previous information as an NG product through the previous information traced back by the two-dimensional code.
The controller is set not to dispense the modules at the positions determined as the modules of the NG products. Namely, after the two-dimension code recognition and the tracing are completed, mark point recognition is carried out. During dispensing, the NG modules are directly skipped over, and only the modules which are judged to be OK products are dispensed. The conventional dispensing equipment is used for dispensing as long as the module flows down from the previous channel, so that time is wasted, and NG products in the previous channel are difficult to recycle and even scrapped, thereby causing unnecessary economic loss.
And after the dispensing is finished, carrying out exposure treatment to solidify the glue. Then, the quality of the module dispensing is detected by the camera 30. The camera 30 may be a dispensing camera of the dispensing mechanism itself, or may be an additionally provided camera.
In some embodiments, the dispensing camera 30 is configured as a high-pixel color camera, and cooperates with the red, green and blue annular light sources to identify the dispensing quality of the module. Specifically, the camera 30 acquires a color image of the module and transmits the color image to the controller, and the controller uses the gray value to identify the glue in the characteristic region, and calculates the ratio of the glue area to calculate the amount of the glue. When the glue area does not reach the preset range, the glue is too little or not. The characteristic region can be but not limited to the end face, the lens base, the glue groove and the like of the module product. In addition, whether the glue overflows or whether the glue is dispensed to a non-dispensing area or not, or glue breaking occurs or a glue line deviates can be judged through gray value distribution. When the non-dispensing area appears in a block shape or a large amount of gray value distribution corresponding to dispensing appears, the glue overflows to the non-dispensing area, wherein the scattered gray value distribution appears and is a scattered point defect. When the gray value after the glue dispensing in the glue dispensing area is discontinuous, the glue breaking is shown. When the glue line shape does not conform to the planned shape, the glue line deviation is shown.
The controller is provided with identification software for identifying the dispensing quality. The parameters of the identification software can be adjusted, and corresponding settings can be carried out according to different product models or production requirements.
In the module detection process, after the dispensing condition of the module is identified, the dispensing condition is bound with the two-dimensional code of the corresponding module, and the two-dimensional code is uploaded to a source database. Therefore, all previous information can be traced according to the two-dimensional code, and defective product circulation is prevented.
Through above technical scheme, this application has following beneficial effect:
(1) The traditional dispensing equipment does not have the processes of management and control, data statistics, binding and the like on the dispensed materials and the dispensed products, and the dispensed products cannot be effectively traced. For conventional equipment, this application can realize some management and control and the traceing back of data of gluing the supplied materials and some gluing products.
(2) The product detection of traditional dispensing equipment is detected through personnel's fleshing eye, and it is undulant to detect greatly, and the standard is not unified, influences the product quality. In the application, the detection is performed by a camera (or other equipment), and the detection accuracy and stability are improved.
(3) In the traditional dispensing equipment, the data of defective products are recorded only by manual quantity, and the development trend of the defective products is not recorded in a whole unified way. This application is through typing data into the database, and the staff can analyze the development trend of the former defective products and the key problem that appears in the operation of gluing, guides the directional debugging of equipment personnel to equipment and research and development personnel to the directional improvement of scheme.
In some embodiments, judge the product that is NG in two-dimensional code scanning stage and module detection stage, accessible point glue equipment reminds, for example, carry out the suggestion of reporting to the police to NG product when detecting, perhaps through screen display for the operator can directly sort out NG product and do not continue the circulation according to reminding or showing.
In some embodiments, the screen display effect matches the tray 70. For example, when dispensing the glue, the modules in the tray 70 are arranged in several rows and several columns, and several rows and several columns are correspondingly displayed on the screen 50 (as shown by 501 in fig. 3). The number of ranks may be manually entered or may be automatically generated as the camera 30 scans.
In some embodiments, the module condition may be indicated on the display screen by different colors, e.g., red for NG products and green for OK products. Meanwhile, bad types of the modules can be displayed at the position corresponding to the screen. And in different situations of the previous bad process, such as the failure of two-dimensional code identification, failure of previous information acquisition, empty previous information and NG product display of the previous information, which are described above, the bad type of the previous process is obtained. The bad types of glue dispensing include too little glue, glue break, glue overflow, glue line offset, etc. as described previously. The operating personnel can be according to the demonstration condition of screen, and direct convenient ground is with the sorting out of bad module classification, makes things convenient for the post-processing after the defective products is categorised, for example, overflows to glue, carries out the frictioning or removes gluey operation.
In some embodiments, the two-dimensional code scanning stage does not sort the defective modules, but sorts the defective modules after the dispensing is completed and the exposure is performed, so that the production efficiency is relatively high. In some embodiments, the defective products are sorted out in the two-dimensional code scanning stage, and then the subsequent dispensing operation is performed. In some embodiments, after the defective products are sorted out in the two-dimensional code scanning stage, the modules that are confirmed to be OK products are added to the tray 70, and then dispensing is performed. Therefore, the whole module box after the dispensing operation is finished can be conveniently circulated.
In some embodiments, after the dispensing is completed, the exposure process is performed directly, and after the glue is cured, the dispensing condition is detected. And then, data entry and identification code binding are performed according to the detection result, the data entry and the identification code binding are uploaded to a database, and finally all defective products are taken out, so that the production efficiency is relatively high. In other embodiments, after dispensing, dispensing detection is performed first, and all defective products are taken out after detection. And then, exposing again, and carrying out one-time dispensing detection after exposure is finished. If the defective products are not glued, data entry is carried out, the data entry is bound with the identification codes and uploaded to the database, and then the defective products are taken out again, so that the defective products caused in the exposure process can be eliminated.
In the application, the bad type of the dispensing procedure and the bad in the previous (previous) procedure of the dispensing procedure can be counted and uploaded to the database. The staff can be according to the data in the database, the key problem that appears in the bad development trend of analysis front track and the gluey process of gluing, and the directional debugging of guide equipment personnel to equipment and research and development personnel to the scheme improves with the orientation.
In other embodiments, the dispensing device can light the module, and read the fusei id (module identification information) of the product through the product drawing, thereby avoiding the defect that the identification code recognition module can only recognize the front identification code. Specifically, the module is placed in a fixture, contacts corresponding to the module connector are arranged in the fixture, and the fixture is communicated with the module through the contacts and the module connector. And after the clamp is electrified, photographing the module, namely, electrifying the product to open the picture to read the FuseID.
Furthermore, the dispensing module can be combined with a focusing module, namely, dispensing and focusing are integrated. The focusing module is a process in front of the dispensing module, in the process, the position of a lens in the module is adjusted to a preset position, so that the lens can clearly form an image, and then the position is fixed through dispensing. After the module focusing is completed, the glue is directly dispensed in the same machine table, the product circulation can be reduced, and the production time is shortened.
In other embodiments, the dispensing device may also be a fully automatic dispensing device. FIG. 3 is a schematic view of a fully automatic dispensing apparatus according to the present application. As shown in fig. 3, the dispensing device mainly comprises an automatic feeding and discharging part, a dispensing mechanism 1 and a sorting mechanism 2.
The dispensing device has a device base 10 which is rectangular and has at least two transverse rails 60. The transverse rails 60 are used for arranging a material tray 70, and the material tray 70 can move back and forth along the transverse rails 60 to realize the dispatching of the dispensing materials. The track 60 is provided with a material bin 31 at the end, the track 60 pulls the material tray 70 out of the material bin 31, and after the dispensing equipment dispenses the material, the material tray 70 can be placed back into the material bin 31. On the opposite sides of the transverse rail 60, there are a dispensing arm and a sorting arm, respectively. The tray 70 can move on the guide rail 60 in the direction of the arrow shown in fig. 3, and first stops dispensing at a position corresponding to the dispensing arm. After the dispensing is completed and the exposure is performed, the tray 70 moves along the guide rail 60 to the sorting mechanism 2, and then stops to perform the sorting operation at the position corresponding to the sorting arm. The sorting mechanism 2 searches a database of the data center, and sorts the defective modules in the material tray 70 into the defective material tray 71 through the suction nozzle 21 according to the detection result in the database. After the defective products are selected, the material tray 70 moves to the material bin along the guide rail and returns to the material bin, so that automatic feeding and discharging are realized.
FIG. 4 is a schematic view of an automatic loading and unloading part. As shown in fig. 4, a plurality of material trays 70 are loaded in the material bin 31, and the material bin 31 can be driven by a driving device to move in the Z-axis direction to drive the material trays 70 therein to move up and down. The guide rail 60 is provided with a clamping device 61, and the clamping device 61 can fix the material tray 70 and drive the material tray 70 to move along the guide rail 60.
Next, the loading process of the clamping device 61 will be described with reference to fig. 4 and 5. As shown in fig. 4, the holding device 61 has a fixed end 611, a movable end 612, a holding bottom 613, and a pushing device 614. As shown in fig. 5, the holding device 61 can move along the guide rail 60 and cooperate with the movement of the compounding bin 31 in the Z-axis direction. When the material tray 70 in the material bin 31 is aligned with the apparatus table 10, the clamping device 61 moves to a position close to the material bin 31 and continues to move to protrude below the material tray 70 in the material bin 31. Then, the material bin 31 moves downward by a distance such that the upper edge of the fixed end 611 of the holding device 61 is higher than the lower end of the material tray 70, and the bottom surface of the material tray 70 contacts with the bottom surface of the holding device 61.
