Description

Technical Field

[0001] The present invention relates to the technical field of end-sealing machine equipment, and in particular to a method and equipment for automatically circulating a material box after unloading from an end-sealing machine. Background Art

[0002] In the end-capping process of the electronic component manufacturing process, the electronic components on the end-capping carrier need to be unloaded into a receiving box after the end-capping process is completed. In common production, only one box is installed on the unloader. With this type of unloader, the box can only be manually taken in and placed, and only one box can be replaced at a time, which may require replacement 10-30 times. This single-box unloading method has the disadvantage of small box capacity and cannot support long-term automatic large-capacity unloading. After the box receives a certain amount of material, it needs to be shut down for processing. The full box needs to be removed manually and replaced with a new one before production can continue. This leads to frequent manual operations, time-consuming and labor-intensive operations, and seriously affects the operating efficiency of the entire line, resulting in low production efficiency.

[0003] For example, in the prior art, patent application publication number CN117352310A discloses a fully automatic terminal sealing machine for chip capacitors. This application document only discloses the processing of the loading tray during the production process, but does not disclose any processing equipment and procedures for improving the efficiency of the material receiving box when the electronic components need to be unloaded into the material receiving box after the terminal sealing process is completed. In this industry, the inventor has not found any other related prior art for automated placement of material boxes. Summary of the Invention

[0060] The working principle of the automatic circulation equipment of the material box after the end sealing machine is unloaded:

[0061] Before the operation of this equipment, the empty material boxes 71 are stacked and stored on the first bottom plate 43 in the empty material box storage bin 11. The empty material box storage bin 11 can store multiple empty material boxes 71 at the same time. An empty material box placement sensor 451 is installed on the first support plate 45 to identify whether the empty material box 71 is in place. The first support plate 45 drives the first rack 42 to move up and down through the first lifting motor 41 and the gear transmission mechanism. The first rack 42 drives the first bottom plate 43 and the four first lifting guide columns 44 to move up and down. The first support plate 45 passes through the empty material box bin rectangular hole 111 provided on the first bottom plate 43 to push the empty material box 71 upward to move up and down. The empty material box high position photoelectric sensor 46 controls whether the empty material box 71 rises to the set highest position and lifts the empty material box 71 to the gripping position of the mechanical gripper 36. The mechanical gripper 36 can move horizontally and vertically. The empty material box low position photoelectric sensor 47 controls whether the empty material box 71 falls to the set lowest position.

[0062] When it is necessary to extract the empty material box 71, the servo motor 33 of the transverse pick-up and place module is driven, and the slide 35 moves linearly to drive the mechanical gripper 36 to operate. The preset program of the equipment system controller controls the mechanical gripper 36 to move to the extraction position of the empty material box 71. The first lifting motor 41 operates to lift the empty material box 71 to the position of the mechanical gripper 36. The gripper cylinder of the mechanical gripper 36 pushes the clamping plate so that the clamping buckle clamps both sides of the empty material box 71; when the clamping action is completed, the sensor installed on the clamping plate judges the empty material box 71. When the judgment result is valid, the first lifting motor 41 descends to the set position, and the mechanical gripper 36 completes the extraction action of the empty material box 71, and the empty material box 71 can be taken to the unloading station to receive the product with the sealed end;

[0063] When the full material box 72 that is filled with material needs to replace the empty material box 71, the mechanical gripper 36 moves to the placement position above the full material box storage bin 12, the second lifting motor 51 of the material box discharge lifting device rotates, and the second support plate 55 rises to reach the position below the mechanical gripper 36 to receive the full material box 72; the gripper cylinder drives the clamping plate to open, releasing the full material box 72. After the full material box 72 is placed, the second lifting motor 51 of the full material box storage bin 12 descends, and the full material box 72 is stored in the full material box storage bin 12. The mechanical gripper 36 returns to the extraction position of the empty material box storage bin 11 to extract a new empty material box 71, thereby completing the operation process of the unloader automatically taking and discharging material boxes.

[0064] The embodiment of the present invention operates automatically throughout the entire process. The empty material box storage bin 11 and the full material box storage bin 12 are controlled by two independently controlled lifting systems. After 20 material boxes are filled, the empty material box storage bin 11 and the full material box storage bin 12 are pulled out by the operator through the slide rail 22 and replaced at one time, thereby reducing the original operation of replacing the material boxes 20 times to once, greatly saving labor and achieving the purpose of improving efficiency.

[0065] The innovation focus of the present invention lies in the method, mechanical structure and connection relationship. The equipment system controller controls the servo motor 33, the first lifting motor 41, the second lifting motor 51, the clamping hand lifting cylinder 37, the clamping hand cylinder, the empty box placement sensor 451, the full box placement sensor 551, the empty box high-position photoelectric sensor 46, the empty box low-position photoelectric sensor 47, the full box high-position photoelectric sensor 56 and the full box low-position photoelectric sensor 57, as well as the corresponding electronic control system through a program. The details will not be elaborated here.

[0066] This embodiment is not limited to the lifting structure and driving method of the current mechanism. Changes in the size and installation method of the structure, changes in the storage quantity of the material box, and replacement of the driving device should all be included in the scope of protection of the present invention.

[0067] The foregoing description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein are intended to be encompassed within the scope of protection of the present invention.
