Embodiment 1
[0040] Such as Figure 3-6 As shown, a hemming cam device includes a rotating main shaft 8, a hooking mechanism 1, a pressing mechanism 2, a turning mechanism 3, and a hammer mechanism 4, wherein,
[0041] The hooking mechanism 1 includes a hooking head 11 and a hooking drive assembly. The hooking drive assembly is connected to the hooking head 11 to drive the hooking head 11 to extend into the fabric to be folded. The outer bottom of the edge makes the edge of the fabric to be folded upward;
[0042] The blanking mechanism 2 includes a blanking head 21 and a first cam subassembly. The blanking head 21 is connected to the rotating main shaft 8 through the first cam subassembly, so as to translate and compress the waiting head 21 along the Z axis. The inner side of the edge of the folded fabric defines the fold line position of the fabric to be folded;
[0043] The flanging mechanism 3 includes a flanging pawl 31, a second cam subassembly, and a third cam subassembly. The flanging p...
Embodiment 2
[0069] Such as figure 1 As shown, an automatic folding machine includes a working table 101, and the hemming cam device and template moving mechanism 10 according to the first embodiment arranged on the working table 101, wherein:
[0070] The template moving mechanism 10 is used to drive the fabric template 11 holding the fabric to be folded 12 to move on the XY plane for the hemming cam device to perform hemming, and the XY plane is parallel to the fabric to be folded 12 is on the plane.
[0071] The automatic folding machine drives the fabric to be folded 12 along the X axis and the Y axis through the template moving mechanism 10, and then cooperates with the translation along the Z axis and rotation around the Z axis of the hemming cam device, which can be aligned The edge trajectory of the fabric 12 to be folded realizes multi-axis positioning, which greatly improves the accuracy of the edge folding positioning. The operator only needs to change the material of the fabric 12 t...
Embodiment 3
[0083] Such as Figure 14 with 15 As shown, a hemming method, which can be applied to the automatic hemming machine described in the second embodiment, includes the following steps:
[0084] Step 1: The control host 13 obtains template data of the fabric 12 to be folded.
[0085] In this step 1, in the template data of the fabric 12 to be folded, the edge trajectory of the fabric 12 to be folded is decomposed into a plurality of hemming points, and each hemming point corresponds to a point in the coordinate system. Expressed as (x, y, β), x is the value of each folding point on the X axis, y is the value of each folding point on the Y axis, and β is the value of each folding point around the Z axis Angle of rotation.
[0086] The template data of the fabric 12 to be folded has been imported and stored in the control host 13 in advance.
[0087] Step 3: According to the template data of the fabric 12 to be folded, the template moving mechanism 10 drives the fabric 12 to be folded to t...
