Description

TECHNICAL FIELD

[0001] The utility model relates to automatic equipment technical field, specifically, relates to a finished product packing device. BACKGROUND

[0002] The existing camera module is generally produced in batches, fed, detected and discharged. The camera module is relatively small in size and is usually placed in a jig tray. The jig tray is usually stacked in multiple layers for material transfer. For example, dozens of camera module products are arranged and placed in one jig tray, and then the whole tray is detected. During the detection process, when NG materials are determined, the NG materials need to be manually removed, and then the qualified products are supplemented to fill the jig tray with qualified products. Finally, the multiple jig trays are stacked and packed for discharge. During the packing process, the stacked jig trays need to be fixed because they are easily scattered and cause the products to fall out of the jig tray. Currently, the jig tray is usually fixed by binding a rubber band. After the rubber band is bound, the packing, labeling and other processes are performed. However, in the existing process, the actions of binding the rubber band, packing and labeling are usually performed separately by multiple devices, which consumes a large amount of manual transfer cost and leads to low production efficiency. Although some semi-automatic devices can realize the continuity of several steps, the device structure is complex and bulky, which increases the cost of the device. SUMMARY

[0045] Fixture tray 4, fixture tray group 5. Detailed Implementation

[0046] Example 1

[0047] Combination Figures 1 to 20 As shown, this embodiment provides a finished product packaging device, including: a feeding, sorting, and replenishing device 1, a storage device 2, and a packaging device 3; wherein,

[0048] The feeding, sorting, and replenishing device 13 includes a feeding mechanism 11, a conveying mechanism 12, a detection mechanism, a sorting mechanism 13, and a replenishing mechanism 14. The feeding mechanism 11 is adapted to transport the jig trays 4 on the feeding station one by one to the conveying mechanism 12. The conveying mechanism 12 is adapted to convey the jig trays 4 at the detection mechanism, the sorting mechanism 13, and the replenishing station, respectively. The sorting mechanism 13 is adapted to remove products that are deemed NG based on the detection results of the detection mechanism. The replenishing mechanism 14 is adapted to grab qualified products from the replenishing jig tray and replenish them into empty positions in the jig trays 4 on the replenishing station. These empty positions can be empty during feeding or empty after unqualified products are removed by the sorting mechanism. In addition, the detection mechanism can use a CCD camera to capture the shape characteristics of the products for identification and analysis to identify products whose shapes do not meet the requirements.

[0049] The storage device 2 is equipped with multiple hoppers 21 and a transfer robot 22. The transfer robot 22 is adapted to grab the jig plate 4 at the replenishment station into the hopper 21 and can grab the jig plate 4 from the hopper 21 onto the transfer mechanism 24 for stacking.

[0050] The packaging device 3 includes a claw mechanism 32, a rubber band binding mechanism 33, a labeling mechanism 34, a packaging mechanism 35, a heat sealing mechanism 39, and a feeding mechanism. The claw mechanism 32 is adapted to grab several stacked jig trays 4 from the transfer mechanism 24 and place them at the rubber band binding station to bind several rubber bands to the jig trays 4. After binding the rubber bands, the jig trays 4 are transported to the labeling mechanism 34 for labeling. The packaging mechanism 35 is adapted to place the entire set of jig trays 4 into a packaging bag 312 and heat-seal the packaging bag 312 using the heat sealing mechanism 39. The feeding mechanism is adapted to feed the packaged entire set of jig trays 4, or to grab them to the labeling mechanism 34 for secondary labeling before feeding.

[0051] Combination Figures 1 to 2 As shown, in this embodiment, the loading station is equipped with a manual loading bin 111, which is suitable for placing multiple unsorted jig trays 4. The jig trays 4 can be driven one by one to the loading mechanism 111 by the material retrieval mechanism 21. The material retrieval mechanism 21 includes a lifting mechanism to drive the jig trays 4 upward. Within the travel range of the loading mechanism 11, there is also a cover unloading station 112 for placing removed cover plates and an NG unloading station 113 for placing jig trays 4 that are NG for barcode scanning or NG for horizontal detection.

[0052] Combination Figures 1 to 4 As shown, the loading mechanism 11 includes a first XZ axis motion mechanism 114 and a conveying mechanism 115 disposed on the first XZ axis motion mechanism 114. The conveying mechanism 115 includes a barcode scanner 1151, a gripper 1152, a suction cup 1153, and a teardrop-shaped horizontal detection mechanism 1154. The conveying mechanism 115 is adapted to first move to the loading station to use the suction cup 1153 to clamp the top cover on the top fixture tray 4 to the top cover unloading station 112, and after removing the top cover, it moves back to the loading station to use the suction cup 1153 and the gripper 1152 to grab the fixture tray 4 after removing the top cover. The barcode scanner 1151 is adapted to scan the product in the fixture tray 4. Here, four suction cups 1153 are provided, and their positions can be adjusted on the conveying mechanism 115 to accommodate fixture trays 4 of different sizes. The suction cup 1153 is used to adsorb the top cover to transport it to the unloading station. It can also assist the gripper 1152 in gripping the jig tray 4 into the conveying mechanism 12 when transporting the jig tray 4. When gripping the top cover, the grippers 1152 on both sides first separate to a preset distance to prevent interference when transporting the top cover.

[0053] Combination Figure 4 As shown, the teardrop-shaped horizontal detection mechanism 1154 includes four teardrop-shaped components distributed around the gripper 1152 and four photoelectric sensors 11546 corresponding to each teardrop-shaped component 11541. The teardrop-shaped components 11541 are naturally swayable and mounted on the conveying mechanism 115, suitable for overlapping the surface of the jig tray 4 during transport. When the height of the jig tray is different in four directions and the warping amplitude is too large, at least one teardrop-shaped component 11541 will sway with a large amplitude, allowing the photoelectric sensors to detect it. When any photoelectric sensor 11546 detects a signal from its corresponding teardrop-shaped component 11541, it is determined that the jig tray 4 is warped, and the material is unloaded to the NG unloading station 113 via the conveying mechanism 115. The teardrop-shaped component 11541 described herein is mounted on the detection bracket 11547. It includes a teardrop-shaped end 11542 and a sensing end 11543. The teardrop-shaped component 11541 is provided with a positioning hole 11544 and a movable through groove 11545. A pin or screw is inserted into the positioning hole 11544 so that the teardrop-shaped component 11541 can swing on the detection bracket 11547. Since one end of the teardrop-shaped component 11541 is relatively heavy, the teardrop-shaped end 11542 of the teardrop-shaped component 11541 will swing downward in a natural state. A pin can be inserted into the movable through groove 11545 to limit the swing arc of the teardrop-shaped component 11541. When the gripper 1152 picks up the jig tray 4, the four teardrop-shaped components 11541 abut against the surface of the jig tray 4. When the jig tray 4 is level, the sensing end 11543 of the teardrop-shaped component 11541 moves out of the detection range of the photoelectric sensor 11546, and at this time, none of the four photoelectric sensors 11546 trigger a signal. However, when the jig tray 4 warps, one or more of the teardrop-shaped components 11541 swing upwards with a large amplitude, thereby swinging the sensing end 11543 into the detection range of the photoelectric sensor 11546. If one of the four photoelectric sensors 11546 is triggered, it is judged as NG (Not Good), and the jig tray 4 is unloaded to the NG unloading station 113 by the loading mechanism 11. For example, Figure 4In the diagram, the teardrop-shaped component 11541 on the left has a larger swing amplitude, and its sensing end 11543 can be detected by the photoelectric sensor, while the sensing end 11543 of the teardrop-shaped component 11541 on the right is not detected by the photoelectric sensor. By setting up the teardrop-shaped horizontal detection mechanism 1154, detection can be performed simultaneously during handling, and the detection logic is simple and efficient, which can effectively prevent unqualified fixture trays 4 from flowing into downstream workstations. At the same time, by integrating the barcode scanner 1151, gripper 1152, suction cup 1153, and teardrop-shaped horizontal detection mechanism 1154 onto the same handling mechanism 115, the structure is compact, which can reduce interference from multiple drive platforms and effectively reduce the size of the equipment.

[0054] Combination Figure 5 As shown, the conveying mechanism 12 includes a transport X-axis 121, a loading and barcode scanning platform 123, a sorting platform 124, and a replenishment platform 125 disposed above the transport X-axis 121. The transport X-axis 121 is equipped with a conveying assembly 122 featuring a first lifting device 1221 and a second lifting device 1222. The conveying assembly 122 is adapted to reciprocate along the transport X-axis 121 to facilitate the transfer of the jig tray 4 between the loading and barcode scanning platform 123, the sorting platform 124, and the replenishment platform 125. The transport X-axis 121 can be driven by a linear motor or a ball screw mechanism; the distance traveled each time is the same, and by reciprocating, the jig tray 4 can be transported from the loading and barcode scanning platform 123 to the sorting platform 124 and the replenishment platform 125. During sorting, the first lifting device 1221 and the second lifting device 1222 descend, placing the two jig trays 4 on the sorting platform 124 and the replenishment platform 125 respectively. Simultaneously, different jig trays 4 are sorted and replenished. After replenishment, the jig trays 4 are transported to the hopper 21 by the transfer robot 22 within the storage device 2. By controlling the movement rhythm of the conveying component 122 in conjunction with the working rhythm of the transfer robot 22, the efficiency of sorting and replenishment can be improved.

[0055] Combination Figure 6As shown, a sorting mechanism 13 is disposed above the sorting platform 124. The sorting mechanism 13 includes a second XZ axis motion mechanism 131 and a sorting robot 132 disposed on the second XZ axis motion mechanism 131. The sorting robot 132 includes a mounting plate 1321 and at least one set of liftable sorting components disposed on the mounting plate 1321. The sorting components include a servo motor 1322, a swing component 1323 connected to the servo motor 1322, and sorting heads 1326 disposed at the left and right ends of the swing component 1323. The sorting heads 1326 are slidably connected to the mounting plate 1321 via guide rails. The servo motor 1322 is adapted to alternately rotate forward and reverse to drive the swing component 1323 to swing, thereby driving the two sorting heads 1326 to move up and down alternately. A sorting CCD 133 is disposed on the sorting robot 132 to perform positioning and barcode scanning on the products. The sorting head includes a vacuum suction cup connected to a vacuum device, and is adapted for both vertical and rotary motion. Rotation allows adjustment of the product angle. During operation, the sorting CCD 133 first photographs and positions non-compliant products based on the detection results from the inspection mechanism. The sorting robot 132 is then moved to the corresponding position, and the sorting head 1326 descends to remove the product. A servo motor drives the swing component 1323 to swing, causing the two sorting heads 1326 to move up and down in tandem. One motor can drive the movement of both sorting heads 1326, effectively reducing the number of motors used, lowering costs, and contributing to a more compact structure. In this embodiment, two sets of sorting robots 132 are provided, which can cover most of the area of ​​the jig tray 4, improving sorting efficiency. It should be noted that an empty jig tray 4 loading mechanism 11 and a jig tray 4 unloading mechanism are provided on the side of the sorting mechanism 13. The empty jig tray 4 loading mechanism 11 is used to place empty jig trays 4 to hold defective products rejected by the sorting mechanism 13, and the jig tray 4 unloading mechanism is used to unload jig trays 4 filled with defective products. It should also be noted that a sensing block 1324 is provided on the swing member 1323, and a photoelectric detection sensor 1325 is provided above the swing member 1323. When the swing member 1323 swings, the sensing block 1324 alternately passes through the sensing range of the photoelectric sensor 11546, thereby identifying whether the sorting head 1326 is in motion.

[0056] Combination Figure 7As shown, the replenishment mechanism 14 includes a third XZ axis motion mechanism 141, a replenishment CCD 142, a replenishment robot 143, and a cover transport mechanism 144 mounted on the third XZ axis motion mechanism 141. The replenishment CCD 142 is suitable for positioning the product. After replenishment, the cover is transported from the cover hopper 21 to the fixture tray 4 via the cover transport mechanism 144. The replenishment robot 143 is equipped with the same sorting components as the sorting robot 132, which can transport qualified products from the fixture tray 4 containing qualified products to the empty space of the fixture tray 4 at the replenishment station. The cover transport mechanism 144 can be configured to be the same as the transport mechanism 115 of the loading mechanism 11, which will not be described in detail here. It should be noted that a replenishment bin 21 and a cover feeding mechanism 11 are provided on one side of the replenishment mechanism 14. The replenishment bin 21 is used to provide the replenishment mechanism 14 with a replenishment jig tray containing qualified products; the cover feeding mechanism 11 is used to lift the covers one by one to a position that the replenishment mechanism 14 can grasp. The cover feeding mechanism 11 and the replenishment bin 21 can be manually fed. The replenishment mechanism 14 can be used to replenish the jig tray and put the covers back onto the jig tray 4, thereby completing the entire process of cover picking-detection-sorting-replenishment-cover placement on the feeding, sorting and replenishing device 1. The entire feeding, sorting and replenishing device 1 has a compact structure and high sorting and replenishment efficiency.

[0057] Combination Figure 8 As shown, the storage device 2 includes multiple hoppers 21 and a transfer robot 22. The transfer robot 22 is adapted to pick up the jig trays 4 at the replenishment station into the hoppers 21, and can pick up the jig trays 4 from the hoppers 21 onto the transfer mechanism 24 for stacking. Here, the storage device 2 is provided with a sampling bin 23, which facilitates the user to take out the jig trays 4 from the sampling bin 23 for sampling inspection. The transfer robot 22 is a five-axis storage transfer robot 22, which can pick up the jig trays 4 from the replenishment platform 125 into the hoppers 21, and can also pick up the jig trays 4 from the hoppers 21 onto the transfer mechanism 24. The transfer mechanism 24 is provided with a transfer platform and a limiting rod. The transfer platform is adapted to stack multiple jig trays 4, for example, it can stack ≤10 jig trays 4 to form a jig tray group 5, and then the jig tray group 5 is transported to the elastic band binding mechanism 33 by the claw mechanism 32. During stacking, the jig disc group 5 can be stacked in a direction with a vertical deviation of 90° to form a "+" shape, which facilitates the subsequent peeling of adjacent jig disc groups 5.

[0058] Combination Figures 14 to 16As shown, the elastic band binding mechanism 33 includes an elastic band frame 334, an elastic band retrieval mechanism, and a rotating platform 333. The retrieval claw mechanism 32 is mounted on a gantry mechanism 31, which has an X-axis motion mechanism and a first Y-axis motion mechanism. The retrieval claw mechanism 32 is vertically and flexibly mounted on the first Y-axis motion mechanism. The gantry mechanism 31 can move back and forth on the frame. The retrieval claw mechanism 32 is configured to transport the stacked jig assembly 5 from the transfer mechanism 24 to above the rotating platform 333. The retrieval claw mechanism 32 has two retrieval claws for retrieval of the jig assembly 5 from the bottom, followed by displacement under the action of the X-axis motion mechanism and the first Y-axis motion mechanism. The retrieval claw mechanism 32 is equipped with a lifting device to drive the retrieval claws to rise and fall. When tying rubber bands, the rubber band taking mechanism takes one rubber band from the rubber band frame 334 in sequence, and then inserts it into the jig plate assembly 5 from the side. Then, the claw mechanism 32 places the jig plate assembly 5 onto the rotating platform 333. After the rotating platform 333 rotates 90°, the claw mechanism 32 grabs the jig plate assembly 5 and moves it to the front of the rubber band taking mechanism, and inserts another rubber band from the side. The above actions are repeated four times so that all four protruding surfaces of the jig plate assembly 5, which are stacked in a cross shape, are fitted with rubber bands.

[0059] In this embodiment, the rubber band retrieving mechanism includes a YZ-axis motion mechanism 331 and a rubber band retrieving assembly 332 mounted on the YZ-axis motion mechanism 331 to retrieve rubber bands from the rubber band holder 334 and attach them to the fixture assembly 5. The rubber band retrieving assembly 332 includes a connecting plate 3321, two transverse slide rails 3322 fixed on the connecting plate 3321, and two longitudinal slide rails 3323 slidably mounted on the transverse slide rails 3322. Each longitudinal slide rail 3323 has two sliders with rubber band rods 3324 slidably mounted on it, and the four rubber band rods 3324 are connected in a guide plate 3325. A ball screw slider is connected between the two longitudinal slide rails 3323. The actuating mechanism 3326 drives the two longitudinal slide rails 3323 to move towards or away from each other along the transverse slide rail 3322, thereby causing the four rubber band rods 3324 to converge or move away under the action of the slider and the guide plate 3325 to loosen or expand the rubber bands. Here, the rubber band frame 334 is manually loaded, and the rubber band frame 334 retrieval mechanism controls the four rubber band rods 3324 to converge for insertion into the rubber band frame 334, and expands after insertion to retrieve the material. After retrieval, the material moves to the fixture plate group 5, and the rubber band is expanded again to a wider width to facilitate entry into the fixture plate group 5. After the rubber band is put into the fixture plate group 5, the rubber band rods 3324 converge again to leave the rubber band in the fixture plate group 5 before exiting. By setting two transverse slide rails 3322 and two longitudinal slide rails 3323 that are slidably set on the transverse slide rails 3322, and with the guiding effect of the guide plate 3325, it is possible to achieve synchronous driving of four rubber band rods 3324 using a single drive mechanism. This improves the synchronicity of the movement of the rubber band rods 3324, optimizes the control logic, and reduces equipment costs.

[0067] It should be noted that the motion mechanisms mentioned in this embodiment are all existing motion devices, which can be automatically controlled and have their working rhythm set through existing control systems, and will not be described in detail here.

[0068] In this embodiment, a sorting mechanism 13 first removes defective products, and then a replenishing mechanism 14 adds qualified products to the jig tray 4, filling it with qualified products. The jig tray 4 is then transported to a storage facility for storage. Random sampling can be performed in the storage facility as needed. When packaging is required, products can be individually removed from the storage facility, stacked, and then bundled together with elastic bands, labeled, and packaged. The elastic band tying mechanism 33, labeling mechanism 34, and packaging mechanism 35 are all operated via a gantry mechanism 31, resulting in a compact structure with complete functions, effectively reducing the overall size of the equipment. This solution improves the efficiency of product sorting and packaging.

The conveying mechanism 12 then conveys the jig tray 4 to the sorting mechanism 13 and the replenishing mechanism 14 in sequence.

[0072] S2. The sorting mechanism 13 removes the NG products from the inspection tray 4 for placing NG products based on the inspection results of the inspection mechanism.

[0073] S3. The feeding mechanism 14 grabs products from the fixture tray 4 containing qualified products and feeds them into the position where the sorting mechanism 13 sorts out the products, so that the fixture tray 4 is filled with qualified products, and takes out the top cover from the top cover feeding mechanism and places it on top of the fixture tray 4.

[0074] S4. The transplanting robot 22 picks up the jig tray 4 from the feeding mechanism 14 and stores it in the silo 21; the transplanting robot 22 picks up the jig tray 4 in the silo 21 one by one and stacks them in the transfer mechanism 24 to form a jig tray group 5.

[0075] S5. After stacking to the preset quantity, the jig tray group 5 is transported to the rubber band binding mechanism 33 by the claw 32 to bind the rubber band; then it is transported to the labeling mechanism 34 by the claw 32 for labeling; after labeling, it is transported to the packaging mechanism 35 by the claw 32 for bagging; after bagging, the bag opening is heat-sealed by the heat sealing mechanism 39.

[0076] S6. After heat sealing, the material is transported by the unloading and handling mechanism 313 or transported to the labeling mechanism 34 for secondary labeling before unloading.

[0077] The method in this embodiment can automatically sort and distribute the products in the jig tray 4, ensuring that each product in the jig tray 4 is a qualified product. Furthermore, the packaging process enables fully automatic binding of rubber bands and packaging, which can improve production efficiency.
