Description

Technical Field

[0001] This utility model relates to the field of sewing equipment, and in particular to a fully automatic double-head gantry sewing machine. Background Technology

[0002] Template sewing is a sewing process that uses automated equipment to cut grooves into an acrylic sheet to the required dimensions, allowing for sewing along the grooved path. It is particularly useful in the automotive interior and luggage industries, where the cut pieces are relatively large. Template sewing significantly improves production efficiency and quality consistency. This modular sewing method simplifies and standardizes complex processes for factories, increasing efficiency, reducing defect rates, improving quality and production time stability, and reducing reliance on highly skilled workers.

[0003] Existing template sewing machines have a fixed sewing machine table, and the template is moved left and right by a clamp to achieve the sewing trajectory. This results in insufficient sewing accuracy. In addition, each time the template is changed, it needs to be replaced manually, which requires stopping the machine to replace it, seriously affecting efficiency. Utility Model Content

[0043] The sewing device 7 in this embodiment is a double-head sewing machine, that is, each sewing device 7 includes an upper head 71 and a lower head 72. The upper head 71 is fixed to the Z-axis support 352. In order to maintain the synchronous and coordinated operation of the upper head 71 and the lower head 72, in this embodiment, as follows: Figure 4 and Figure 5As shown, each sewing machine 7 has a lower head 72 equipped with a second drive mechanism 73 located below the work area 112.

It should also be noted that, in order to control costs in this embodiment, the X-axis rack 733 in the two sets of second drive mechanisms 73 is shared, that is, only one X-axis rack 733 is disposed.

[0045] This utility model uses a sewing template 2 for feeding and sewing. Generally, two sewing templates 2 exist simultaneously during the operation of this equipment: one is placed in the work area 112 for sewing, and the other is placed in the feeding area 111 awaiting transfer to the work area 112 for sewing. The feeding of the sewing template 2 can be pre-prepared, or the sewing template 2 can be placed in the feeding area 111 first and then fed, depending on actual needs. For the transfer of the sewing template 2, this embodiment uses a first conveying mechanism 4 and a second conveying mechanism 5 to move the sewing template 2 between the feeding area 111 and the work area 112. At the same time, to realize the movement of the first conveying mechanism 4 and the second conveying mechanism 5, this embodiment uses a first displacement mechanism 6, as detailed below:

[0046] like Figure 6As shown, the first displacement mechanism 6 includes a first fixed base 61 fixed in the base 1, a first displacement motor 62 disposed on the first fixed base 61, and two sets of first displacement transmission belts 63, first displacement drive wheel 64 and first displacement driven wheel 65 symmetrically disposed on both sides below the feeding area 111. The two ends of the first displacement transmission belt 63 are arranged in a loop around the first displacement drive wheel 64 and the first displacement driven wheel 65. The first displacement drive wheel 64 is linked to the first displacement motor 62 through a transmission shaft 66. The first conveying mechanism 4 and the second conveying mechanism 5 are respectively connected to the upper and lower ends of the first displacement transmission belt 63 and are staggered.

[0047] like Figure 6 and Figure 7 As shown, the first conveying mechanism 4 includes a sixth slide rail 41 fixed to the base 1, a first conveying seat 42 movably disposed on the sixth slide rail 41, and a first conveying cylinder 43 fixed to the first conveying seat 42. The first conveying cylinder 43 is connected to a first conveying connector 44. The first conveying seat 42 is provided with a first connecting arm 45. The first connecting arm 45 is connected to a first displacement transmission belt 63. The first conveying connector 44 is a rod-shaped structure. The bottom of the rear end of the sewing template 2 is provided with a second connector 21 corresponding to the position of the first conveying connector 44. The second connector 21 is provided with a first through hole 211 for passing through the first conveying connector 44. A tapered through part 441 is formed at the end of the first conveying connector 44.

[0048] like Figure 8 As shown, in this embodiment, the four sides of the sewing template 2 are spliced ​​together from profiles with slots 22, such as aluminum profiles with slots 22 in the top, bottom, left, right, and center. The position of the first through hole 211 is placed in the slot 22. Therefore, after the first conveying connector 44 is inserted, it is placed in the slot 22. The first through hole 211 abuts against the middle position of the first conveying connector 44. When the first conveying mechanism 4 is started, the second connector 21 can share the thrust of the first conveying connector 44, making the overall sewing template 213 move more smoothly.

[0049] like Figure 6 As shown, the second conveying mechanism 5 includes a second conveying slide rail 51 fixed to the base 1, a second conveying seat 52 slidably disposed on the second conveying slide rail 51, and a second conveying cylinder 53 fixed to the second conveying seat 52. A third conveying slide rail 54 is provided on the second conveying seat 52, and a third conveying sliding seat 55 is movably connected to the third conveying slide rail 54. The second conveying cylinder 53 is connected to the third conveying sliding seat 55. A support member 56 is provided at the end of the third conveying sliding seat 55. A second connecting arm 521 is provided on the second conveying seat 52, and the second connecting arm 521 is connected to the first displacement transmission belt 63.

[0050] Of course, in order to coordinate the various mechanisms and ensure synchronous operation, an electronic control system is also provided in this embodiment.

[0051] Brief description of the working principle of this utility model: During operation, all mechanisms are in their initial positions. Two or more sets of sewing templates 2 can be prepared in advance for feeding. Then, with the help of a robotic arm or manual labor, the sewing templates 2 are placed on the feeding area 111 of the work platform 11. The initial positions are the first conveying mechanism 4 in the work area 112 and the second conveying mechanism 5 in the feeding area 111. After the equipment is started, the second conveying cylinder 53 is activated to raise the support 56. During the raising process, the support 56 abuts against both sides of the sewing template 2 and drives the sewing template 2 to rise. Then, the first displacement mechanism 6 is activated, and the first displacement transmission belt 63 rotates to drive the second conveying seat 52 to move along the second sliding groove 15 to the work area 112. The sewing template 2 will also move to the work area 112. When the sewing template 2 reaches the work area 112, the first displacement mechanism 6 stops, and then the second conveying cylinder 53 is reset, lowering the sewing template 2 until the support 56 is removed from the sewing template 2. Then, the first displacement mechanism 6 is activated again to lower the second conveying cylinder 56 to the work area 112. The second conveyor mechanism 5 is driven to the loading area 111. Simultaneously, the first conveyor mechanism 4, driven by the first displacement mechanism 6, moves along the first sliding groove 14 to the working area 112. At this time, the first conveying cylinder 43 is activated to lift the first conveying connector 44, so that the through part 441 can be inserted into the first through hole 211 and placed in the slot 22 of the steel section. This enables the sewing template 2 placed in the working area 112 to be positioned for auxiliary sewing. Then, the two sets of sewing equipment 7 perform synchronous and coordinated operations according to the sewing trajectory preset by the equipment's electronic control system. After the sewing operation is completed, the first displacement mechanism 6 is activated, driving the first conveyor mechanism 4 and the second conveyor mechanism 5 to move. The first conveyor mechanism 4 drives the sewing template 2 that has been sewn to the loading area 111. When the sewing template 2 that has been sewn reaches the loading area 111, it can be unloaded or replaced with a new sewing template 2. While the first conveyor mechanism 4 moves, the second conveyor mechanism 5 moves the new sewing template 2 to the working area 112. This process is repeated.

[0052] 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.
