Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please refer to Figure 1-5 ;

[0027] The equipment described in this utility model aims to realize the entire process of production and testing, and improve work efficiency. Specifically, it includes a conveying device 21 and an injection molding device 1, with a transfer device 3 and a testing camera 4 located between the two. The conveying device 21 is equipped with a fixture 22. In this embodiment, the injection molding device 1 includes a turntable device 11, which is equipped with at least two lower mold bases 12. An upper mold base 13 is provided corresponding to one of the lower mold bases 12. The upper mold base 13 should be set on a lifting frame, and the upper and lower mold bases 12 are in a vertical injection molding system. This part belongs to the prior art and will not be described in detail here. A cleaning device 6 is provided on the outside corresponding to the other lower mold base 12.

[0028] Of course, the loading device 51 and unloading device 54 can be used to achieve fully automatic loading and unloading operations. However, since the substrate used to produce LED packaging brackets is also relatively small, it is also possible to operate it manually. This is not a limitation here.

[0029] During operation, the substrate is obtained from the fixture 22 by the transfer device 3, and then placed into the lower mold base 12 located on the outside. During this process, it passes through the detection camera 3 4, which is located below. The detection camera 3 4 captures the current state of the substrate, and then the transfer device 3 adjusts the position of the substrate to correspond to the position of the mold core in the lower mold base 12. In this embodiment, the transfer device 3 can be a combination of a multi-axis robot and a suction cup, or a combination of a moving component, a rotary cylinder, and a suction cup, etc. Preferably, after the substrate is placed into the lower mold base 12, the detection camera 2 652 also monitors the substrate. The position of the board is inspected a second time to ensure that the substrate is accurately placed in the lower mold base 12. Since the LED packages are very small, even a slight offset will cause the cup of the entire substrate to be misaligned and scrapped. Therefore, the yield can be improved by the second inspection. Then, the substrate is injected by the injection molding device 1 to form several cups on the substrate and finally form several very small LED package brackets. Then, the injection molded product is rotated out along with the lower mold base 12 by the turntable device 11. Then, the injection molded product is inspected by the inspection camera 652 to check for defects.

[0030] More specifically, this device has two sets of detection programs for the second detection camera 652. One program is used to detect the position of the substrate in the lower mold base 12, and the other program is used to detect the quality of the finished product. The switching signal between the two programs comes from the feeding signal of the transfer device 3 and the injection signal in the injection molding device 1.

[0031] When the transfer device 3 places the substrate into the lower mold base 12, the detection camera 652 detects the position of the substrate in the lower mold base 12. When the substrate enters the injection molding device 1 for injection molding, the detection device 652 switches to the program of detecting finished products to detect whether the finished products have defects. Of course, the above is only one implementation method. In actual applications, the switching function can be realized according to other signals.

[0032] After injection molding is completed, the transfer device 3 removes the product from the injection molding device 1 and puts it back into the fixture 22. The finished product is then transported to another location through the fixture 22. Preferably, two fixtures 22 can be set up, one for loading and the other for unloading.

[0033] In this embodiment, a feeding device 51 and a discharging device 54 are also included. The feeding device 51 is used to place the substrate into the fixture 22. The discharging device 54 is provided with a finished product storage bin 52 and a defective product storage bin 53. If the finished product is qualified, it is placed into the finished product storage bin 52 through the discharging device 54. If it is unqualified, it is placed into the defective product storage bin 53.

[0034] Preferably, it also includes a detection camera 7, used to acquire the position of the finished product in the fixture 22 and send it to the unloading device 54.

[0035] This invention integrates previously scattered processes through the cooperation of various devices, realizing integrated operation of injection molding production and testing of LED packaging brackets, reducing ineffective operations in the intermediate process, and improving work efficiency.

[0036] After the transfer device 3 removes the finished product from the injection molding device 1, the cleaning device 6 cleans the lower mold base 12 to prevent dust and material adhering to the mold core from affecting the injection quality of the next finished product.

[0037] Based on a further extension of the above embodiments, the inspection camera 3 4, in addition to detecting the initial position of the substrate, also has the function of detecting the bottom state of the finished product. After the transfer device 3 takes the product out of the injection molding device 1, it will pass through the inspection camera 3 4 again. The inspection camera 3 4 is set below so that the bottom of the finished product can be directly observed. The inspection camera 3 4 detects whether there are defects in each LED packaging device on the bottom of the finished product. Through the cooperation of the inspection camera 2 652 and the inspection camera 1 641, the finished product can be inspected from all angles, which can better improve the quality of the product.

[0038] This invention further describes the cleaning device 6, specifically including a multi-axis moving assembly 61. The moving end of the multi-axis moving assembly 61 is equipped with an air blowing assembly 62 and a brush assembly 63. After one LED substrate is injection molded, it is rotated out via a turntable device 11 along with the lower mold base 12, causing another lower mold base 12 to align with the upper mold base 13 for another injection molding. At this time, the LED bracket substrate that has completed injection molding on the lower mold base 12 is removed by a material handling device in the production line. Then, driven by the multi-axis moving assembly 61, the air blowing assembly 62 and the brush assembly 63 sequentially pass through the lower mold core. The air blowing assembly 62 outputs a high-speed airflow to the lower mold core to blow away the dust on the surface. Then, the brush assembly 63 contacts the lower mold core to clean away the dust adhering therein. Preferably, the multi-axis moving assembly 61 drives the air blowing assembly 62 and the brush assembly 63 to reset, and then passes through the lower mold core again to perform a second cleaning, which can improve the cleaning effect. In addition, a detection camera 641 is fixed on the frame of the multi-axis moving assembly 61. After the cleaning operation is completed, the cleaning position is checked by the detection camera 641 to check the cleanliness. If the detection camera 641 shows that there are still impurities in the lower mold core, the above cleaning process is repeated multiple times. If there is no significant improvement after multiple cleaning processes, an alarm is sent to the control system to notify the staff to handle it.

[0039] Furthermore, the detection camera 2 652 is mounted on the extension mounting part 2 651, which is located on the multi-axis moving assembly 61, thus saving installation space.

[0040] This invention can effectively clean the mold core in the lower mold base 12 through the air blowing component 62 and the brush component 63. It can also perform secondary cleaning during the resetting process to ensure the cleaning effect. Finally, the cleaning position is observed through the detection camera 641 to ensure that it is clean and to avoid impurities affecting the finished product during injection molding.

[0041] In addition, since the detection camera 641 is located at the rear and in a relatively dark location, supplementary lights 642 are provided on both sides of the detection camera 641.

[0042] One embodiment of the present invention relates to a brush assembly 63, specifically including a fixed base 631, on which a plurality of drive motors 632 are provided. The drive motors 632 are longitudinally mounted and extend out of the fixed base 631, and a brush head 633 is installed at the output end of the drive motors 632. It should be noted that the multi-axis moving assembly 61 includes at least an X-axis module and a Z-axis module. The Z-axis module drives the brush assembly 63 to move up and down, so that the brush comes into contact with it. Then, the drive motors 632 drive the brush to rotate and sweep away the dust.

[0043] One embodiment of the present invention relates to the air blowing assembly 62, specifically including two extension mounting members 621. The extension mounting member 621 can be a bar or a flat sheet, as long as it can provide support. The two extension mounting members 621 are respectively provided on both sides of the fixed base 631 for installing the air tube 622. The side wall of the air tube 622 is provided with several air holes 623, and the air tube 622 is located on the front side of the brush assembly 63. The air holes 623 are inclined towards the lower mold base 12. Air nozzles are provided on both sides of the air tube 622 for connecting to the air tube. The air tube method has a simple structure, and the design of the air holes 623 allows for a larger airflow range, which is more conducive to cleaning.

[0044] Preferably, the extension mounting part 621 is provided with an adjustment slot 624. The bolt passes through the slot 624 and connects to the fixing seat 631. By setting the slot 624, not only can the extension distance of the extension mounting part 621 be adjusted, that is, the distance between the air tube and the brush, but also the angle can be rotated around the bolt, that is, the orientation angle of the air hole 623 can be adjusted. Finally, the extension mounting part 621 is pressed and fixed by locking the bolt and the fixing seat 631. This design facilitates installation, debugging and adjustment according to different products.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
