[0035] In actual application of this embodiment, when the automatic tray - matching composite fixture needs to be used, the main substrate 101 at one end of the composite fixture is connected to the robotic arm that drives the fixture, and the robotic arm drives the rotation, flipping, and lifting of the composite fixture. The robotic arm used is a prior - art means in the fixture field, and the structure of the robotic arm will not be specifically described here. When it is necessary to clamp special - shaped laminate materials, first, the robotic arm drives the overall flipping of the composite fixture so that the side of the adsorption plate 103 faces the side of the material to be clamped. At this time, by driving the driving cylinder 201 on one side of the side plate 102, the driving plate 202 can be driven to stretch on one side of the side plate 102. And when the driving plate 202 extends outwards, several laminate suction cups 204 assembled on the driving plate 202 extend towards the side of the adsorption plate 103, and the extending length of the end of the laminate suction cup 204 exceeds the height of several carton suction cups 3 on one side of the adsorption plate 103. After the laminate suction cup 204 adheres to one side of the laminate, a vacuum is established and the robotic arm drives the main substrate 101 to lift and lower, thereby grasping the special - shaped laminate and moving it.

[0036] When it is necessary to grasp carton materials, the robotic arm drives the side of the adsorption plate 103 towards the carton and aligns several carton suction cups 3 on it with the carton. At this time, the driving cylinder 201 on one side of the side plate 102 is in a contracted state, and the extending length of the carton suction cup 3 is greater than the length of one side of the laminate suction cup 204. When the carton suction cup 3 adheres to the surface of the carton, a vacuum is established on the surface of the carton through the carton suction cup 3, and through several carton suction cups 3 arranged in an array, multiple points on the surface of the carton can be stably adsorbed. Even in the case where the vacuum establishment fails at some points, the carton materials can still be stably grasped.

[0037] When it is necessary to grasp circular or annular materials, first, the servo - motor 401 arranged on one side of the bottom plate 104 drives the driving gear 402 to rotate. During the rotation of the driving gear 402, the driven gear 504 is driven to rotate through meshing. One end of the driven gear 504 is meshed with the driving gear 402, and the other end drives the sliding member 502 to slide on the guide rail groove 501, and several sliding members 502 move synchronously, thereby realizing the diameter - expanding movement of the sliding member 502 on the guide rail groove 501. Through the sliding member 502 with an adjustable diameter and the jaw assembly 6 assembled on it, circular or annular materials with different diameters can be adapted and quickly clamped, thereby realizing the composite clamping function of the composite fixture.

[0038] Please refer to Figure 1 , in a preferred embodiment of the invention, the machine - frame member 1 further includes a robotic - arm flange 105, and the robotic - arm flange 105 is arranged on one side of the main substrate 101 and is used to connect the robotic arm that drives the movement of the main substrate 101.

[0039] In a case of this embodiment, the robotic arm flange 105 can be connected to robotic arms with various degrees of freedom through a standard flange, and the robotic arm is not specifically limited herein.

[0040] Please refer to Figure 2 , in a preferred embodiment of the invention, the laminate clamping mechanism 2 further includes an elastic buffer rod 203, and the elastic buffer rod 203 is disposed between the driving plate 202 and the laminate suction cup 204 for elastically connecting the laminate suction cup 204 and the driving plate 202.

[0041] In actual application of this embodiment, the elastic buffer rod 203 elastically connects the driving plate 202 and the laminate suction cup 204, so that when the laminate suction cup 204 fits against one side of the special-shaped laminate, there is enough buffer clearance, and at the same time, the contact effect between the laminate suction cup 204 and the laminate is improved, ensuring that the laminate suction cup 204 can stably fit on the laminate surface, thereby achieving a stable adsorption effect.

[0042] Please refer to Figure 7 , in a preferred embodiment of this embodiment, the sliding jaw member 5 further includes a connecting groove 503, and the connecting groove 503 is fixedly assembled at one end of the sliding member 502 for assembling and connecting the jaw assembly 6.

[0043] In a case of this embodiment, the end of the connecting groove 503 preferably adopts a fan-shaped structure for limiting the extreme sliding distance of one side of the sliding member 502.

[0044] Please refer to Figure 8 , in a preferred embodiment of the invention, the jaw assembly 6 includes: a jaw arm 601, the jaw arm 601 is fixedly assembled on one side of the connecting groove 503; an anti-slip pad 602, the anti-slip pad 602 is fixedly disposed at the end of the jaw arm 601 for increasing the friction; and a buffer rubber 603, the buffer rubber 603 is disposed on the surface of the jaw arm 601 for increasing the buffer effect.

[0045] In actual application of this embodiment, the anti-slip pad 602 is assembled at the end of the jaw arm 601, and the anti-slip pad 602 can increase the friction between the jaw arm 601 and the material, so that it is not easy to fall during the clamping process. The surface of the jaw arm 601 is also provided with a buffer rubber 603, and the buffer rubber 603 can increase the clamping clearance between the jaw arm 601 and the material, having a certain buffer effect on the material and effectively preventing the material from being clamped and damaged.

[0046] In a case of this embodiment, the anti-slip pad 602 preferably adopts a polyurethane material, and the polyurethane material has excellent friction coefficient and resilience performance, which can improve the service life of the anti-slip pad 602 and increase the clamping effect on the material.

[0047] Please refer to Figure 8 , in a preferred embodiment of the invention, a limit detection mechanism 7 is further assembled on one side of the jaw assembly 6. The limit detection mechanism 7 includes: a limiter 701 fixedly disposed on one side of the bottom plate 104; and a limiting member 702 movably assembled at one end of the limiter 701 and disposed toward the side away from the bottom plate 104.

[0048] In actual application of this embodiment, when the bottom plate 104 moves toward the material side, the limiting member 702 on one side of the limiter 701 can detect the distance between the bottom plate 104 and the material. When the distance value is less than the safety threshold, it can achieve the effect of safety alarm, avoid the fixture body from hitting and squeezing the material, and improve the safety effect of the fixture.

[0049] Please refer to Figure 1 , in a preferred embodiment of the invention, a box dropping detection sensor 8 is further disposed on one side of the carton suction cup 3. The box dropping detection sensor 8 is used to detect the adsorption state of the box on one side of the carton suction cup 3.

[0050] In actual application of this embodiment, when the box adsorbed on one side of the carton suction cup 3 drops, the box dropping detection sensor 8 can quickly control the robot arm to stop through signal negative feedback after detecting the box dropping, and detect its abnormal adsorption state.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
