[0038] like Figure 1-Figure 4 As shown, this embodiment provides a material changing device for a placement machine, which includes a material finding head device 1, and the material finding head device 1 includes a grabbing component 11 and a clamping head component 12. Specifically, the grabbing component 11 includes a first displacement driving component 111 and a grabbing component 112 and a rotating driving component 113 arranged at the output end of the first displacement driving component 111. The grabbing component 112 is used to grab the material tray 20, and the rotating driving component 113 is used to drive the material tray 20 to rotate; the clamping head component 12 includes a first driving member 121, a first claw 122 and a second claw 123, and the first driving member 111 is used to grab the material tray 20. The first driving member 121 is connected to the first claw 122 and the second claw 123. The first driving member 121 is used to drive the first claw 122 and the second claw 123 to open and close. The top of the first claw 122 is higher than the top of the second claw 123. The first displacement driving member 111 can move the material tray 20 above the clamping head assembly 12. The top of the first claw 122 can be in contact with the material strip in the material tray 20. The rotation driving member 113 drives the material tray 20 to rotate, so that the end of the material strip can move between the first claw 122 and the second claw 123 under the guidance of the first claw 122. In this embodiment, the first driving member 121 is a clamping cylinder.

[0039] During operation, the first displacement driving component 111 drives the grabbing component 112 to move above the hopper 10, and the grabbing component 112 grabs the material tray 20 in the hopper 10, and then the first displacement driving component 111 drives the grabbing component 112 to move above the clamping head assembly 12. At this time, the first driving component 121 drives the first claw 122 and the second claw 123 to open, and the top of the first claw 122 is attached to the material belt in the material tray 20. The rotating driving component 113 drives the material tray 20 to rotate. When the end of the material belt moves to the front of the first claw 122, the end of the material belt moves to between the first claw 122 and the second claw 123 under the interference guide of the first claw 122, and then the first driving component 121 drives the first claw 122 and the second claw 123 to merge, realizing automatic material head finding, reducing labor costs, improving production quality, and improving the production efficiency and accuracy of the placement machine.

[0040] In this embodiment, Figure 2 As shown, the rotation drive component 113 includes a fifth drive member 1131 and a silicone wheel 1132. The fifth drive member 1131 is drivingly connected to the silicone wheel 1132 and is used to drive the silicone wheel 1132 to rotate. When the grasping component 112 grasps the material tray 20, the silicone wheel 1132 presses against the circumferential sidewalls of the material tray 20. When the silicone wheel 1132 rotates, the silicone wheel 1132 can drive the material tray 20 to rotate. In this embodiment, the fifth drive member 1131 is a servo motor. After the grasping component 112 grasps the material tray 20, the material tray 20 can rotate relative to the grasping component 112. The grasping component 112 is conventional.

[0041] Preferably, if Figure 3 As shown, the gripping head assembly 12 further includes a second visual sensor 124, which is used to detect the material strip between the first gripping claw 122 and the second gripping claw 123. When the second visual sensor 124 detects the presence of the material strip between the first gripping claw 122 and the second gripping claw 123, the first driving member 121 drives the first gripping claw 122 and the second gripping claw 123 to grip the ends of the material strip.

[0042] In this embodiment, the first displacement drive component 111 can drive the grasping component 112 and the rotation drive component 113 to move along the first direction and the third direction, the first direction is the X direction, and the third direction is the Z direction. The first displacement drive component 111 can be coordinated with two linear modules, or the first displacement drive component 111 can be equipped with a robot, wherein the linear module and the robot are both existing technologies and will not be repeated here.

[0043] Preferably, if Figure 3As shown, the material-finding head device 1 also includes a shearing assembly 13, which includes a second displacement drive component 131 and a shearing component 132. The second displacement drive component 131 is driven and connected to the shearing component 132 and can drive the shearing component 132 to move in a first direction; the first displacement drive component 111 can drive the material tray 20 to move in a third direction, so that a shearing station is formed between the material tray 20 and the clamping head assembly 12, and the second displacement drive component 131 can drive the shearing component 132 to move to the shearing station, and the shearing assembly 13 can shear the material strip. After the clamping head assembly 12 clamps the end of the material strip, the first displacement drive component 111 drives the material tray 20 to move in the third direction, forming a shearing station between the material tray 20 and the clamping head assembly 12, and the second displacement drive component 131 drives the shearing component 132 to move to the shearing station, and the shearing component 132 cuts the material strip, realizing automated shearing and removing excess leader tape, lamination, and empty material strips on the material strip. In this embodiment, the second driving member 1321 is a clamping cylinder, and the second displacement driving component 131 can adopt a linear module.

[0044] In this embodiment, the shearing assembly 132 includes a second driver 1321 and two shear blocks 1322. The second driver 1321 is operatively connected to the two shear blocks 1322 to move the two shear blocks 1322 toward or away from each other. When the second displacement driver 131 drives the shearing assembly 132 to the shearing station, the two shear blocks 1322 are opened, allowing the material strip to be positioned between the two shear blocks 1322. The second driver 1321 then drives the two shear blocks 1322 toward each other, achieving shearing. In this embodiment, the second driver 1321 is a clamping cylinder.

[0045] Preferably, the shearing assembly 13 also includes a winding component 133. A second displacement drive component 131 is drivably connected to the winding component 133. The winding component 133 includes a third drive member 1331 and two spaced-apart winding rods 1332. The third drive member 1331 is drivably connected to the two winding rods 1332 to cause the two winding rods 1332 to wind around each other. The second displacement drive component 131 is capable of driving the shearing component 132 to move to the shearing station so that the material strip is positioned between the two winding rods 1332. After the second displacement drive component 131 drives the shearing component 132 to move to the shearing station, the material strip is positioned between the two winding rods 1332. The third drive member 1331 then drives the two winding rods 1332 to wind around each other, winding the material strip until the paper strip reaches the shearing component 132. In this embodiment, even with a relatively small shearing station, the excess leader tape, laminating film, and empty strip on the material strip are completely removed, reducing the size of the equipment. In this embodiment, the third drive member 1331 is a servo motor.

[0046] In this embodiment, the coiling component 133 further includes a stopper 1333. The second displacement driving component 131 is provided with a fixed seat 1311. The stopper 1333 is rotatably connected to the fixed seat 1311. The stopper 1333 is provided with a plurality of through-holes, and two coiling rods 1332 are respectively provided in the through-holes. The stopper 1333 is provided on the fixed seat 1311. Therefore, when the second displacement driving component 131 drives the shearing component 132 to move in the first direction, the stopper 1333 remains stationary in the first direction. When the coiling rods 1332 rotate, the coiling rods 1332 can drive the stopper 1333 to rotate relative to the fixed seat 1311. After the shearing of the material strip is completed, the second displacement driving component 131 drives the shearing component 132 to retract. The waste material on the two coiling rods 1332 cannot pass through the ribs between adjacent through-holes. Therefore, the waste material can automatically separate from the coiling rods 1332 under the interference of the stopper 1333, thereby achieving waste material recovery.

[0047] In this embodiment, a first visual sensor 134 is provided on the side of the stop block 1333 near the material strip. First visual sensor 134 is used to detect the material strip. When first visual sensor 134 detects the paper strip on the material strip, third drive member 1331 stops driving reel 1332, and second drive member 1321 drives shear block 1322 to shear the material strip.

[0048] Preferably, if Figure 4 As shown, the material head finding device 1 also includes a material head fixing component 14, the material head fixing component 14 includes a third displacement driving component 141 and a clamping component 142, the third displacement driving component 141 is driven and connected to the clamping component 142, and is used to drive the clamping component 142 to move between the shearing component 13 and the material tray 20, the clamping component 142 includes a fourth driving component 1421 and two fixed jaws 1422, the fourth driving component 1421 is driven and connected to the two fixed jaws 1422, so that the two fixed jaws 1422 are close to or away from each other. When the shearing station is formed between the material tray 20 and the clamping head assembly 12, the third displacement drive component 141 drives the clamping component 142 to move between the shearing assembly 13 and the material tray 20. After the first visual sensor 134 detects the paper strip on the material strip, the fourth drive component 1421 drives the two fixed clamping jaws 1422 toward each other to clamp the material strip, and then shears the material strip. At this time, the sheared material strip from the material tray 20 is fixed to the material head fixed assembly 14, ready for subsequent splicing. In this embodiment, the fourth drive component 1421 is a clamping jaw cylinder.

[0049] In this embodiment, the third displacement drive component 141 can drive the grasping component 112 and the rotation drive component 113 to move along the second direction and the third direction, where the second direction is the Y direction and the first direction, the second direction and the third direction are perpendicular to each other. The third displacement drive component 141 can be equipped with two linear modules.
