Technical Field

[0001] The utility model relates to a kind of, in particular to an automatic integrated sewing device. Background Art

[0002] In actual applications, traditional special industrial sewing equipment is highly dependent on the precise coordination of operators, that is, through visual monitoring, manual adjustment and precise control to meet specific sewing operation requirements. Although there are CNC sewing machines with a high degree of automation on the market, such equipment often requires professional technicians to program and set up to execute the automated sewing process, and the purchase cost is high. It does not support the economical and efficient modular transformation and upgrading of existing old sewing machines, and the only way to update the equipment is to replace the whole machine.

[0003] Therefore, it is urgent to develop an innovative solution that can realize the adaptive transformation and integrated intelligent upgrade of old sewing machines, thereby avoiding expensive overall replacement investment. The goal of this new system is to significantly reduce the cost of transformation and use, while simplifying the operating process, greatly reducing the company's dependence on skilled workers, and effectively reducing labor expenses.

[0011] Sewing equipment, located on one side of the frame, used for sewing the fabric to be processed;

[0012] The control module is communicatively connected with the grasping mechanism, the position driving mechanism, the visual recognition module and the sewing device.

[0013] Furthermore, a first rotating motor is provided at one end of the first rocker arm away from the second rocker arm.

[0014] Furthermore, a second rotating motor is provided at one end of the second rocker arm connected to the first rocker arm.

[0015] Furthermore, the gripping mechanism includes a pressing plate, a connecting block arranged on the top of the pressing plate, an elastic seat arranged above the connecting block, and a spring arranged between the elastic seat and the connecting block, and the elastic seat is installed at the bottom of the driving shaft of the driving motor.

[0016] Furthermore, the gripping mechanism also includes positioning cylinders arranged at both ends of the pressure plate, a positioning portion is provided on a downward side surface of the output end of each positioning cylinder, and a corresponding positioning hole is provided on the mold.

[0017] Furthermore, the grabbing mechanism also includes a horizontal driving assembly arranged at both ends of the pressing plate, and the mold is provided with a vertical portion corresponding to the horizontal driving assembly, and the vertical portion is provided with a positioning hole.

[0018] Furthermore, the first rotating motor is located at the bottom of the first rocker arm and mounted on the top of the frame.

[0019] Furthermore, a mounting groove for a sewing device is provided on the frame, and the sewing device can move back and forth along the length direction of the mounting groove.

[0020] Furthermore, a vertical plate is provided on one end of the second rocker arm away from the first rocker arm for installing a vertical linear module.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] 1. Compared with the prior art, the uniqueness of the utility model lies in its ability to make full use of existing sewing equipment resources for reuse and optimization and upgrading. Among them, the original sewing machine frame as a core component is retained and integrated. In the actual production process, by installing a specific mold, the visual recognition module can automatically identify the mold type, and the control center can retrieve the corresponding pattern version and supporting processing flow accordingly. After the fabric to be processed is accurately placed in the preset workstation, the position drive mechanism will guide the grabbing device to move accurately to the position, effectively press and fix it, and then transfer it to the sewing work area to perform the corresponding processing steps. This solution does not require too much physical modification of the original sewing equipment and its frame structure, but only needs to effectively connect it to the control module to achieve automated operation. The grabbing mechanism controlled by the position drive mechanism can simulate and replace the manual frequent rotation and positioning of the fabric, and successfully realizes an efficient and automated sewing process. In this way, not only the cost investment of equipment transformation is greatly reduced, but also the difficulty of operation and technical threshold are significantly reduced.

[0023] 2. Compared with the prior art, the utility model abandons the reliance on professional CNC personnel to set programs to achieve automatic sewing, and instead uses pattern patterns as the key element of automatic identification and positioning. The visual recognition module can automatically match and call the corresponding processing program by parsing the unique information of the pattern pattern. In this process, the pattern pattern essentially plays a dual role: it is not only an identifier for system identification and execution of the process, but also a position reference for guiding the position drive mechanism to accurately move the gripping mechanism. In this way, the movement and rotation of the fabric to be processed are completed by the gripping mechanism under the control of the position drive mechanism, so that the sewing equipment only needs to focus on its core function-starting and stopping the sewing operation in a timely manner according to instructions. That is, the sewing equipment only needs to respond to the control module's signal about when to start sewing and when to end sewing, without the need for manual or complex program control of the movement of the fabric, thereby realizing a more intuitive and easy-to-operate automated sewing process.

[0024] 3. The gripping mechanism, position driving mechanism, visual recognition module and control module of the utility model can form a separate module or device, which is independent of the sewing equipment and can therefore be produced separately. The sewing equipment can be replaced with different models, making the combination more flexible and reducing the subsequent maintenance cost.

[0025] 4. Compared with the prior art and other solutions, the position drive mechanism of the utility model can realize high-speed movement of the grasping mechanism in the horizontal plane through the design of the first rocker arm and the second rocker arm, which is similar to a manipulator and is particularly suitable for large-angle rotation or complex trajectory positioning.

[0034] The frame 1 is provided with a workbench 11 having a smooth surface;

[0035] In this embodiment, the frame 1 may be a part of the original sewing device 7. A mounting groove is provided on the frame 1. The sewing device 7 is installed in the mounting groove, and the sewing device 7 can move back and forth along the length direction of the mounting groove.

[0036] Mold 2, serving as a processing pattern plate, is used to press onto the fabric to be processed;

[0037] In this embodiment, the mold 2 is a processing pattern plate, and the sewing device 7 sews along the edge of the mold 2 during sewing, so that the required pattern or line can be sewn on the fabric to be processed.

[0038] A gripping mechanism 3 is detachably connected to the mold 2 and is used to press the mold 2 downward so that the fabric to be processed is clamped between the mold 2 and the workbench 11;

[0039] In this embodiment, the gripping mechanism 3 includes a pressing plate 31, a connecting block 32 disposed on the top of the pressing plate 31, an elastic seat 33 disposed above the connecting block 32, and a spring 34 disposed between the elastic seat 33 and the connecting block 32, and the elastic seat 33 is installed at the bottom of the driving shaft 51 of the driving motor 5. Preferably, the gripping mechanism 3 also includes positioning cylinders 35 disposed at both ends of the pressing plate 31, and a positioning portion is provided on a side surface of the output end of each positioning cylinder 35 facing downward, and a corresponding positioning hole is provided on the mold 2. In this way, the mold 2 can be fixed by inserting the positioning portion of the output end of the positioning cylinder 35 into the positioning hole, and then contracting or stretching the output end of the positioning cylinder 35. Among them, the provision of the spring 34 can prevent the fabric from being unable to slide on the workbench 11 due to excessive pressure.

[0040] More preferably, the gripping mechanism 3 further includes a horizontal driving assembly 36 disposed at both ends of the pressing plate 31, and a vertical portion 37 corresponding to the horizontal driving assembly 36 is disposed on the mold 2, and a positioning hole is disposed on the vertical portion 37. Compared with the previous method, this method is easier to implement, and the mold 2 can be quickly disassembled and assembled by only sucking or releasing the vertical portion 37 or entering and exiting the positioning hole of the vertical portion 37 through the horizontal driving assembly 36. Preferably, the horizontal driving assembly 36 is two cylinders, and can also be a vacuum suction cup structure or an electromagnetic structure.

[0041] The position driving mechanism 4 includes a driving motor 5 connected to the top of the grasping mechanism 3, a vertical linear module 46 for driving the driving motor 5 to move up and down, a second rocker arm 42 for driving the vertical linear module 46 to rotate and swing on a horizontal plane, and a first rocker arm 41 for driving the second rocker arm 42 to rotate and swing on a horizontal plane, so as to move the grasping mechanism in the height direction and the horizontal direction and rotate 360°;

[0042] In this embodiment, a first rotary motor 44 is provided at one end of the first rocker arm 41 away from the second rocker arm 42, the first rotary motor 44 is located at the bottom of the first rocker arm 41 and mounted on the top of the frame 1, a second rotary motor 45 is provided at one end of the second rocker arm 42 connected to the first rocker arm 41, and a vertical plate 421 is provided on one end of the second rocker arm 42 away from the first rocker arm 41 for mounting a vertical linear module 46. The drive motor 5 is mounted on the slide of the vertical linear module 46 through the adapter plate 43.

[0043] Compared with the structure using the XYZ three-axis linear module, the solution of the utility model focuses on the processing of arc patterns, executes at a faster speed than the XYZ three-axis linear module, and has simpler control logic. It is especially suitable for complex path adjustments in three-dimensional spaces that require a large range and rapid changes in direction.

[0044] A visual recognition module 6 is provided above the gripping mechanism 3 and is used to identify the model of the mold 2;

[0045] In this embodiment, the visual recognition module 6 can use a common QR code scanning device or a standard camera on the market as the hardware basis, and can accurately identify the model of the mold 2 by carrying mature visual recognition technology. When the mold 2 is successfully identified, the control center will automatically call out the corresponding processing program from the stored pattern library, thereby guiding the automated execution of the entire sewing process.

[0046] Sewing equipment 7, arranged on one side of the frame 1, for sewing the fabric to be processed;

[0047] In this embodiment, the sewing device 7 is an existing product, preferably a CNC model that can receive control signals.

[0048] The control module 8 is communicatively connected with the gripping mechanism 3, the position driving mechanism 4, the visual recognition module 6 and the sewing device 7. The control module 8 retrieves the corresponding pattern according to the model of the identified mold 2, and controls the position driving mechanism 4 and the sewing device 7 for processing according to the pattern.

[0049] Preferably, in the storage system of the control module 8, a set of pattern database is preferably pre-set, and the features of the mold 2 are quickly and easily identified through the visual recognition module 6. It is worth noting that the visual recognition process does not require the use of complex image recognition algorithms. It only needs to identify specific identification information on the mold 2, such as a QR code, pattern shape or other unique structural elements (such as size, outline, etc.), to quickly associate and call the corresponding pattern data stored in the control module 8. This design allows operators to easily complete the selection and application process of pattern patterns without having a professional CNC knowledge background. In addition, in order to ensure that the pattern library always keeps pace with the times, this solution also supports real-time updates and maintenance through OTA (Over-the-Air) wireless methods, which greatly enhances the flexibility and ease of use of the system.

[0050] Example 2

[0051] The control method of the automated integrated sewing device 7 comprises the following steps:

[0052] Initialization phase: I. Position and place the fabric to be processed at the preset loading station of the workbench 11, and trigger the system start command.

[0053] Process execution steps: II. After receiving the start command, the central control module 8 immediately instructs the position driving mechanism 4 to move, guides the grabbing mechanism 3 to move accurately above the fabric to be processed and performs a downward pressing action to ensure that the fabric is firmly fixed.

[0054] III. After the fabric is fixed, the position driving mechanism 4 continues to be controlled by the control module 8, and the grabbing mechanism 3 carries the fabric to be processed and moves smoothly to the designated processing station.

[0055] IV. After arriving at the processing position, the visual recognition module 6 reads the information of the mold 2 in real time, and the central control module 8 quickly retrieves and calls the corresponding pattern and detailed processing program data according to the recognized mold 2 model.

[0056] V. Based on the acquired pattern and processing parameters, the central control module 8 precisely controls the sewing machine and the position drive mechanism 4 to operate in coordination and perform precise sewing operations according to a predetermined process path.

[0057] VI. After the processing is completed, the central control module 8 issues a reset command to orderly guide the sewing machine and the position drive mechanism 4 to return to the initial state and prepare for the next round of production tasks.

[0058] The parts not described in detail in the present invention are prior art, so the present invention does not describe them in detail.

[0059] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0060] Although this article uses more terms such as frame 1, mold 2, gripping mechanism 3, position driving mechanism 4, driving motor 5, visual recognition module 6, sewing equipment 7, control module 8, workbench 11, pressing plate 31, connecting block 32, elastic seat 33, spring 34, positioning cylinder 35, horizontal driving assembly 36, vertical part 37, first rocker arm 41, second rocker arm 42, vertical plate 421, adapter plate 43, first rotary motor 44, second rotary motor 45, vertical linear module 46, driving shaft 51, etc., it does not exclude the possibility of using other terms.
