Description

Technical Field

[0001] This utility model relates to the field of insulated luggage processing technology, specifically to a sewing board for manufacturing insulated luggage. Background Technology

[0002] In the manufacturing process of insulated bags (such as takeaway boxes, cold chain transport boxes, etc.), it is necessary to sew the edges of multiple layers of insulation fabric. Currently, this process mainly relies on manual operation. Operators need to manually place the fabric under the sewing machine and push the fabric with experience and feel to move it along the predetermined sewing path.

[0003] The existing manual sewing method has significant drawbacks: 1. Sewing quality is highly dependent on the operator's skill level, and problems such as skewing and uneven stitch spacing can easily occur due to operator fatigue or skill differences, resulting in poor product quality stability. 2. Manual operation is inefficient, becoming a bottleneck process in mass production, increasing operational difficulty and the defect rate. Therefore, a sewing platform for manufacturing insulated bags is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a sewing board for manufacturing insulated bags.

[0005] The technical solution adopted by this utility model to solve its technical problem is a sewing table for manufacturing insulated bags, including a sewing table surface, a desktop robotic arm and a sewing template provided on the sewing table surface, an equipment frame installed at the bottom of the sewing table surface by bolts, the desktop robotic arm is an automated robotic arm, and its control host can be assembled below the equipment frame, the desktop robotic arm is fixedly installed at one end of the top of the sewing table surface by bolts, and a sewing machine is installed at one end of the sewing table surface and the desktop robotic arm, and the sewing template is located below the end arm of the desktop robotic arm;

[0006] The suture template includes a lower template and an upper template. The upper template is placed on top of the lower template. Both the lower template and the suture table are made of ultra-high molecular weight polyethylene (UHMWPE). The surfaces of the UHMWPE lower template and the suture table have high self-lubricating properties, which can promote a smooth sliding effect when the two are in contact and moving.

[0007] By adopting the above technical solution, a sewing platform device is provided for edge sewing operations of products such as insulated boxes and takeout boxes, and is designed to work in conjunction with automated sewing machines. The desktop robotic arm replaces the traditional manual arm, and the lower and upper templates in the sewing template press the insulated box fabric to be sewn together in the middle. The template has pre-reserved grooves for the sewing path, thus replacing manual sewing, making the sewing path more standardized, and reducing the skewing caused by the uncontrollable human experience.

[0008] Specifically, the lower and upper templates have through-holes for the sewing path. The bottom corner of the upper template has a downward-protruding positioning post with a rounded chamfered bottom. The top corner of the lower template has a positioning post hole corresponding to the positioning post. The positioning post and the positioning post hole are inserted and positioned to improve the fit between the lower and upper templates. The rounded chamfered positioning post is easier to insert into the positioning post hole. The height of the positioning post hole needs to be greater than the thickness of the sewn product.

[0009] Specifically, the top of the upper template is connected to a protrusion, and at least one set of the protrusion is provided. The top surface of the protrusion is provided with an internal hexagonal positioning socket.

[0010] Specifically, a pressure plate is bolted to the bottom of the end effector of the desktop robotic arm, and the bottom of the pressure plate is integrally connected with hexagonal positioning blocks corresponding to the number and position of the internal hexagonal positioning sockets.

[0011] By adopting the above technical solution, the desktop robotic arm inserts into the hexagonal positioning socket through the hexagonal positioning block under the pressure plate and applies downward pressure to press and fix the upper template, the insulation box fabric, and the lower template onto the sewing table. The desktop robotic arm pushes the sewing template to the position on the sewing table based on the operator's set running trajectory, so that the sewing path groove automatically moves under the sewing machine to cooperate with the sewing machine for sewing work. After sewing is completed, the desktop robotic arm lifts up, the operator opens the upper template, and replaces the insulation box fabric sewn by the lower group. When dealing with insulation box products of different sizes, the required sewing path groove and template of the required size can be changed.

[0012] The beneficial effects of this utility model are as follows: By combining a desktop robotic arm and a dedicated sewing template, the manual operation of pushing fabric is completely replaced, ensuring that the sewing thread strictly follows the path defined by the template. This eliminates the problem of skewed stitching caused by insufficient human experience, achieving standardization and consistency in product quality. The automated operation cycle is stable, reducing manual operation steps and preparation time, and significantly improving production efficiency. It is particularly suitable for mass production. Through the modular sewing template design, by changing templates of different specifications and groove paths, it can quickly adapt to the production needs of insulated bags of different sizes and shapes. The equipment has strong versatility. Utilizing the self-lubricating properties of ultra-high molecular weight polyethylene material, it ensures smooth template movement. The hexagonal positioning insertion mechanism and positioning post holes ensure accurate and reliable gripping and pressing, and the entire system operates stably. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, the insulated bag manufacturing sewing table of this utility model includes a sewing table 2, a desktop robotic arm 21 and a sewing template 22, and a support frame 1 is assembled at the bottom of the sewing table 2.

[0021] The sewing table 2 is securely mounted on the top of the equipment frame 1 by bolts. Both the sewing table 2 and the lower template 221 are made of ultra-high molecular weight polyethylene board, which utilizes its excellent self-lubricating properties and strength to reduce moving friction. An industrial sewing machine is installed on the end of the sewing table 2 away from the desktop robotic arm 21. The desktop robotic arm 21 is fixed to the sewing table 2 by bolts, and its control host can be installed in the space below the equipment frame 1.

[0022] The sewing template 22 consists of a lower template 221 and an upper template 222. The upper template 221 and the upper template 222 have sewing path grooves 223 according to the shape of the edge sewing required for the insulated bag to be sewn. Each of the four corners at the bottom of the upper template 222 is provided with a positioning post 225 with a rounded chamfer. The positioning post 225 can be added or removed according to the actual positioning requirements. The corresponding position of the lower template 221 is provided with a positioning post hole 226. The top of the upper template 222 is fixed with a protrusion 227 by bolts or glue. Each protrusion 227 is machined with an internal hexagonal positioning socket 228.

[0023] The end of the desktop robotic arm 21 is bolted with a pressure plate 211, and the bottom of the pressure plate 211 is fixed with a hexagonal positioning block 212 corresponding to the position of the protrusion 227.

[0024] In use, the operator lays the cut insulated bag fabric flat on the lower template 221, then covers it with the upper template 222. Initial alignment is achieved by the cooperation of the positioning pins 225 and positioning pin holes 226. Upon receiving the command, the desktop robotic arm 21 moves above the template, descends, and precisely inserts the hexagonal positioning block 212 into the inner hexagonal positioning socket 228. Subsequently, the robotic arm applies sufficient downward pressure to press the template and fabric firmly onto the sewing table 2. Then, the robotic arm moves according to a preset program trajectory, causing the entire template assembly to slide, allowing the sewing path grooves 223 to pass sequentially under the sewing machine needle, completing the automated sewing. After the task is completed, the robotic arm lifts up, the operator removes the sewn product, inserts new fabric, and begins the next cycle. When changing products, only the entire sewing template 22 needs to be replaced, and the corresponding processing program can be called in the robotic arm control system.

[0025] The shape and position of the stitching path groove (223) on the template are set according to actual needs.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
