Description

Technical Field

[0001] The invention relates to the technical field of end-capping machine equipment, and in particular to a method and equipment for automatically circulating a material box after unloading from an end-capping 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 the receiving box after completing the end-capping process. In common production, only one material box is installed on the unloader. For this type of unloader, the material box can only be manually taken in and put out, and only one material box can be replaced at a time, which may need to be replaced 10-30 times. This single-box unloading method has a small material box capacity and cannot support long-term automatic large-capacity unloading. After the material box receives a certain amount of material, it needs to be stopped for processing. It is necessary to manually remove the full material box and replace it with a new one before continuing production, resulting in frequent manual operations, time-consuming and labor-intensive, seriously affecting the operating efficiency of the entire line and low production efficiency.

[0003] For example, in the prior art, publication number CN117352310A discloses a fully automatic terminal sealing machine for chip capacitors.

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

[0061] Before the operation of the 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. The first pallet 45 is equipped with an empty material box placement sensor 451 to identify whether the empty material box 71 is in place. The first pallet 45 drives the first rack 42 to rise and fall 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 rise and fall. The first pallet 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 rise and fall. 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 up and down. The empty material box low-position photoelectric sensor 47 controls whether the empty material box 71 drops 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-and-place module is driven, and the slide 35 runs linearly to drive the mechanical gripper 36 to run. 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, and the first lifting motor 41 runs 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 the two 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 that has been sealed;

[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 and release 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 whole process of the embodiment of the present invention is automatically operated. The empty material box storage bin 11 and the full material box storage bin 12 are controlled by two sets of 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 achieving the original operation of replacing 20 material boxes into one time, 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 gripper lifting cylinder 37, the gripper 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, and the corresponding electronic control system through a program, which will not be elaborated in detail 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 protection scope of the present invention.

[0067] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
