Description

Technical Field

[0001] This utility model relates to the technical field of dual-disc alternating feeding devices, specifically, to a dual-disc alternating feeding device. Background Technology

[0002] Automated feeding structures are a key component of modern stamping production lines, enabling automation and high-efficiency production. They typically consist of a material rack, servo-driven or mechanical feeding mechanisms, and a material guiding system, automatically and accurately feeding coiled or sheet materials into the die at predetermined frequencies. This structure not only significantly improves production efficiency and feeding accuracy, ensuring product consistency, but also frees operators from hazardous work areas, effectively protecting their personal safety, and laying a solid foundation for building unmanned, intelligent workshops.

[0003] However, most of the automatic feeding devices on existing stamping production lines require changing to the next tray after feeding the previous batch of materials. During this time, the operation of all subsequent workstation modules will be halted, resulting in reduced production efficiency. Moreover, the complex mechanisms added to some automatic feeding devices to achieve alternating feeding, such as multi-layer guides or partitions, not only occupy a lot of space but also bring risks of easy positioning misalignment and mechanical jamming.

[0038] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0039] like Figures 1 to 9 As shown, a dual-disc alternating feeding device is used, including but not limited to, for feeding stamping, slitting, and other related processing equipment to improve efficiency and accuracy. Specifically, it includes a feeding machine base 1, which mainly supports the various structures in the device and houses related electrical facilities.

[0040] To achieve alternating, seamless feeding, this embodiment includes a feeding bin inside the feeding machine 1, within which a first feeding platform 2 is placed. This fully utilizes the internal space of the feeding machine 1, facilitating the replenishment of materials to be processed by workers or other equipment to the first feeding platform 2. A first drive mechanism is installed at the lower part of the first feeding platform 2 to drive the first feeding lifting mechanism. Additionally, a feeding port 11 and a feeding inlet 12 are respectively provided on the top and side of the feeding bin. The feeding port 11 provides a passage for the first feeding platform 2 to be lifted out of the feeding machine 1 for feeding. The feeding inlet 12 allows workers and related equipment to replenish materials from the side of the feeding machine 1 after the first feeding platform 2 returns to the feeding bin, without occupying the feeding space above the feeding port 11.

[0041] In this embodiment, the second loading platform 4 is installed on one side of the loading port 11. When all the workpieces to be processed in the first loading platform 2 are removed, materials can be retrieved from the second loading platform 4, maintaining the continuity of the equipment's loading. Since this embodiment is adaptable to stamping and slitting equipment, some workpieces are protected by protective partitions placed between two layers of workpieces during stacking. After removing the upper layer of workpieces, the protective partitions must be removed before the next workpiece can be retrieved. Therefore, this embodiment also provides a storage platform 7 for storing the protective partitions on the loading machine 1. The protective partitions can be removed by the dual-axis loading mechanism for temporary storage. Therefore, in order to save space and improve the compactness of this embodiment, an equipment mounting frame 8 is provided on the surface of the feeding machine platform 1, and the storage platform 7 is located on the upper part of the second feeding platform 4. It is then divided into a storage basket 71 and a support frame 72. The support frame 72 is then fixedly connected to the equipment mounting frame 8. The storage basket 71 is mounted on the support frame 72 and can be fixed to the support frame 72 by fasteners, or it can be simply mounted. After the protective partition is filled, it is convenient to replace the storage basket 71.

[0042] To prevent the second loading platform 4 from being blocked by the storage platform 7, this embodiment also provides a second driving mechanism to drive the second loading platform 4. When alternating loading is required, it moves to the upper part of the loading port 11 and maintains the same loading position as the first loading platform 2. It cooperates with the dual-axis loading mechanism to load materials without affecting the use of the storage platform 7.

[0043] The aforementioned dual-axis feeding mechanism is located on the upper part of the second feeding platform 4. It is mainly used to place the workpieces to be processed from the first feeding platform 2 or the second feeding platform 4 into the vision positioning mechanism 6, and after removing one workpiece, remove the protective partition on the next workpiece and place it into the storage basket 71.

[0044] To accomplish the above operations, the dual-axis loading mechanism in this embodiment mainly comprises three modules: a first Z-axis traveling mechanism 91, a second Z-axis traveling mechanism 92, and an X-axis traveling mechanism 93. The X-axis traveling mechanism 93 is mounted on the equipment mounting frame 8 and, through a driver and a slide rail, moves the worktable 7 along the path to the vision positioning mechanism 6. In this embodiment, this direction is defined as the X-axis. The first Z-axis traveling mechanism 91 and the second Z-axis traveling mechanism 92 are both mounted on the X-axis traveling mechanism 93. Through a driver and a slide rail, they drive a material-picking suction cup (or a gripper, not specifically limited in this embodiment) mounted on its output shaft to reciprocate up and down, picking up and placing materials. In this embodiment, this direction is defined as the Z-axis. By setting up the first Z-axis traveling mechanism 91 and the second Z-axis traveling mechanism 92, they can be responsible for picking up and placing the workpiece and the protective partition respectively, without interference, resulting in high efficiency.

[0045] Since this embodiment uses a material suction cup for material handling, corresponding negative pressure equipment and pipelines are required within the feeding platform 1 to ensure normal operation of the device. This will not be elaborated upon in this embodiment. Simultaneously, the distance between the first Z-axis traveling mechanism 91 and the second Z-axis traveling mechanism 92 should be the same as the distance (vertical projection direction) between the feeding station of the first feeding platform 2 or the feeding station of the second feeding platform 4 and the placement platform 7, and the distance (vertical projection direction) between the feeding station of the first feeding platform 2 or the feeding station of the second feeding platform 4 and the visual positioning mechanism 6. This ensures that when the first Z-axis traveling mechanism 91 picks up material, the second Z-axis traveling mechanism 92 can simultaneously place the protective partition on the placement platform 7; and when the first Z-axis traveling mechanism 91 unloads material, the second Z-axis traveling mechanism 92 can simultaneously pick up the protective partition from the first feeding platform 2 or the second feeding platform 4, allowing for synchronous alternating operations with high efficiency.

[0046] In this embodiment, the second loading platform 4 includes a second shelf 41 and a second base 42. The second shelf 41 is used to store the workpiece to be processed, and the second base plate 412 is used to support the second shelf 41 and cooperate with the second drive mechanism. The second drive mechanism includes a second loading driver 51 and a second loading guide rail 52 mounted on the surface of the loading platform 1. The second loading guide rail 52 has two sets and is located on both sides of the loading port 11. The second base 42 is slidably connected to the second loading guide rail 52 to ensure stable support for the second loading platform 4. Then, the second loading driver 51 is mounted on the equipment mounting frame 8 and connected to the second base 42, thereby driving the second loading platform 4 to reciprocate along the second loading guide rail 52.

[0047] Furthermore, since the storage platform 7 is located above the second loading platform 4, to facilitate workers or related equipment in replenishing the second storage rack 41 with parts to be processed, the structure of the second storage rack 41 is divided into a second limiting side plate 411 and a second storage base plate 412. Then, a second feeding slide rail 43 is provided on the second storage base 42. By sliding the second storage base 412 and the second feeding slide rail 43 together, the second storage rack 41 can be pulled out in the direction away from the equipment mounting frame 8, avoiding the upper space being blocked by the storage platform 7. In order to improve the automation level of this embodiment, a second feeding rack 44 is added to the bottom of the second storage base plate 412, and a second feeding driver 45 is added to the second storage base 42. The output shaft of the second feeding driver 45 is sleeved with a second feeding gear that meshes with the second feeding rack 44, which can be used to drive the second storage rack 41 to automatically move and reset towards the equipment mounting frame 8.

[0048] Since different workpieces have different dimensions, this embodiment adds a second limiting rod 413 to the second shelf 41 and opens a second strip hole 414 in the second shelf base plate 412. The second limiting rod 413 is fixedly connected to the second strip hole 414 by a detachable fastener (such as a bolt), so that the fixed position of the second limiting rod 413 can be adjusted within the length range of the second strip hole 414. Then, by setting two sets of second limiting rods 413, the distance between the two second limiting rods 413 can be adjusted while keeping the workpiece storage space centered to accommodate workpieces of different dimensions (lengths). Meanwhile, in order to adjust the lateral (width) of the second shelf 41, this embodiment also uses the second limiting rod 413 as a support mechanism. A second adjusting groove 415 is formed on the surface of the second limiting rod 413, so that the second limiting side plate 411 is slidably connected to the second adjusting groove 415 through the second adjusting slider 416. Then, after the second adjusting slider 416 is adjusted to the appropriate position, it can be fixedly connected to the second adjusting groove 415 through a detachable fastener. This embodiment sets four second limiting side plates 411, all of which are "L" shaped structures, located at the four corners of the upper part of the second shelf base plate 412, forming a limiting range. They can cooperate with the second limiting rod 413 in the height direction to simultaneously limit four degrees of freedom (excluding the degree of freedom restriction caused by the second shelf base plate 412).

[0049] Since the first loading platform 2 in this embodiment has the same function as the second loading platform 4, it has the same structure as the second loading platform 4. Several can be prefabricated and used alternately. The specific structure of the first loading platform 2 will not be described in this embodiment.

[0050] However, since the moving direction of the first loading platform 2 is different from that of the second loading platform 4, the first driving mechanism includes a first support platform 31 and a first driver 32. The output shaft of the first driver 32 is fixedly connected to the bottom of the first loading platform 2 through the first support platform 31, which can drive the first loading platform 2 to rise and fall. The first support platform 31 is used to support the first loading platform 2 after it has been reset, and to share the load of the first driver 32. Several support pads 311 and several elastic buffers 312 are provided on the surface of the first support platform 31. When the first loading platform 2 descends, it can be buffered by the support points and the elastic buffers 312 (such as elastic buffers) to avoid the first support platform 31 or the first driver 32 being damaged due to the excessive weight of the first loading platform 2 during descent.

[0051] Since there may be positional deviations in the placement of the workpiece, this embodiment uses a visual positioning mechanism 6 to identify the position of the workpiece for easy correction. Based on the feeding direction of the workpiece, the mechanism is installed on the side of the loading port 11 facing away from the second loading platform 4 to prevent the workpiece from backtracking and improve loading efficiency. Specifically, the visual positioning mechanism 6 includes a positioning platform 61 for placing the workpiece. An image acquisition device 62 located on top of the positioning platform 61 captures an image to identify the orientation of the workpiece relative to the positioning platform 61 and whether there are any positional or angular deviations. These deviations are then adjusted and corrected through the mechanism itself or subsequent processes. Furthermore, this embodiment also adds a feeding mechanism installed on the loading platform 1, located at the bottom of the positioning platform 61. Through the cooperation of a feeding slide rail 63 and a feeding driver 64, the positioning platform 61 and the feeding slide rail 63 are slidably connected. The feeding driver 64 then drives the feeding mechanism to reciprocate along the feeding slide rail 63, sending the identified workpiece to the next workstation.

[0052] The working steps of this embodiment are as follows:

[0053] 1. Load the parts to be processed into the first loading platform 2 and the second loading platform 4;

[0054] 2. The first drive mechanism lifts the first loading platform 2 to the loading station, and the X-axis traveling mechanism 93 moves the first Z-axis traveling mechanism 91 to the upper part of the first loading platform 2, and the suction cup descends to pick up the material;

[0055] At this time, if there is an unplaced protective partition on the second Z-axis traveling mechanism 92, the storage platform 7 can be placed there;

[0056] 3. After the first Z-axis traveling mechanism 91 completes the material picking, it rises and resets. Driven by the X-axis traveling mechanism 93, it moves to the upper part of the vision positioning mechanism 6, lowers the suction cup, places the picked-up workpiece on the positioning table 61, and then the suction cup rises and resets.

[0057] At this time, the second Z-axis traveling mechanism 92 can descend to pick up the uppermost protective partition of the first loading platform 2, and then rise;

[0058] 4. After the first Z-axis traveling mechanism 91 completes the unloading, it returns to the upper part of the first loading table 2 to pick up the next workpiece;

[0059] If the workpiece in the first loading platform 2 has been picked up, it will be lowered and reset. The second drive mechanism will drive the second loading platform 4 to move to the upper part of the loading port 11, replacing the first loading platform 2 for the first Z-axis traveling mechanism 91 to pick up the workpiece.

[0060] At this time, the first feeding platform 2 is simultaneously replenished through the feeding port 12, without delaying the feeding process;

[0061] 5. After the first loading platform 2 has finished feeding, it can be selected to drive the second loading platform 4 to reset and continue to feed the first Z-axis traveling mechanism 91 from the first loading platform 2. Alternatively, the first loading platform 2 can be switched to feed the workpiece after the workpiece on the second loading platform 4 has been picked up.

[0062] When the first feeding platform 2 is feeding materials, if the second feeding platform 4 needs to be replenished, the second feeding driver 45 can push out the second shelf 41 to replenish the materials, so as to avoid being blocked by the shelf. After the replenishment is completed, the platform is reset.

[0063] This embodiment makes full use of the vertical space of the device to integrate multiple feeding, unloading, picking and vision recognition modules into the feeding machine 1, and makes full use of the internal space of the feeding machine 1 to design feeding and replenishing space and channel for the first feeding platform 2. The structure is compact, occupies little space, and can be used with various processing equipment.

[0064] This embodiment does not limit the specific structure of the suction cup. The appropriate material handling mechanism, such as a negative pressure suction cup or a gripper, can be replaced according to product needs.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
