Description

Technical Field

[0001] This utility model relates to the field of material gripping technology, and in particular to a material gripping mechanism. Background Technology

[0002] During the lower plastic assembly process, the light aluminum sheet needs to be aligned and joined with the lower plastic assembly first. Then, the joined assembly is picked up by a transfer device and placed at the hot melt welding position for hot melt operation.

However, the grippers usually hold the assembly along its side wall and support its bottom wall. Since there is no upper limit on the assembly, the assembly is prone to vibration or displacement during the gripping process, which can easily lead to problems such as loosening of the connection between the aluminum sheet and the lower plastic, displacement of the assembly, or even falling off.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0034] During the lower plastic assembly process, the aluminum sheet and the lower plastic assembly need to be aligned and joined first. Then, a transfer device is used to grip the joined assembly and place it at the hot-melt welding position for hot-melt welding. The transfer device usually includes two grippers that grip the aluminum sheet and lower plastic assembly. However, the grippers generally hold the assembly along the side wall and support the bottom wall of the assembly. But because there is no upper limit on the assembly, the assembly is prone to vibration or displacement during the gripping process, which can easily lead to problems such as loosening of the connection between the aluminum sheet and the lower plastic, displacement of the assembly, or even falling off.

[0035] In response, this embodiment provides a material gripping mechanism to solve the problem that the assembly is prone to vibration or displacement during the clamping process in the prior art, and can be used in the field of material gripping technology.

[0036] Reference Figures 1-4 The material gripping mechanism includes a base 1, a gripper assembly 2, and a floating assembly 3. The gripper assembly 2 is disposed on the base 1 and is used to grip the two side walls of the material 100 and to support the bottom wall of the material 100, thereby achieving the gripping of the material 100 and limiting the material 100 along the bottom and side walls. In this embodiment, the material 100 is an assembly of a light aluminum sheet and a lower plastic sheet assembled and aligned. In other embodiments, the material 100 can also be other plate-shaped or sheet-shaped structures. The floating assembly 3 includes a floating block mounting plate 31, an elastic element 32, and a floating block 33 connected in sequence. The floating block mounting plate 31 is fixed relative to the base 1. The floating block 33 is used to abut against the top wall of the material 100. The elastic element 32 is used to provide an elastic force to press the floating block 33 against the top wall of the material 100. Thus, during the process of the gripper assembly 2 clamping the material 100, the floating block 33 abuts against the top wall of the material 100, and the elastic element 32 provides an elastic force to press the floating block 33 against the top wall of the material 100. Thus, the floating assembly 3 limits the material 100 along the top wall of the material 100, and can press the material 100 tightly against the gripper assembly 2. During the clamping process, the material 100 can be prevented from vibrating or shifting.

[0037] Continue to refer to Figures 1-4 In the floating component 3, multiple elastic elements 32 and multiple floating blocks 33 are provided. Multiple elastic elements 32 are connected to multiple floating blocks 33 in a one-to-one correspondence, and one end of each of the multiple elastic elements 32 is connected to the floating block mounting plate 31. Thus, the multiple elastic elements 32 and multiple floating blocks 33 abut against the top wall of the material 100 at different positions to increase the stability of the limit and further prevent the material 100 from vibrating or shifting.

[0038] Continue to refer to Figures 1-4 Of the multiple floating blocks 33, some floating blocks 33 are disposed on one side of the gripper assembly 2, and others are disposed on the other side of the gripper assembly 2, thereby limiting the material 100 to the top wall along both sides of the gripper assembly 2 to improve the limiting effect. In this embodiment, four elastic elements 32 and four floating blocks 33 are provided, with two elastic elements 32 and two floating blocks 33 disposed on one side of the gripper assembly 2, and the other two elastic elements 32 and four floating blocks 33 disposed on the other side of the gripper assembly 2.

[0039] Continue to refer to Figures 1-4The gripper assembly 2 includes a gripper drive 21 and two grippers 22. The gripper drive 21 includes a fixed end 211 of the gripper drive fixedly connected to the base 1 and two reciprocating ends 212 of the gripper drive reciprocating relative to the fixed end 211 along a first direction. The first direction is parallel to the horizontal plane. Figures 1-2 The floating block mounting plate 31 is fixedly connected to the fixed end 211 of the gripper drive component. Two grippers 22 are connected one-to-one to the telescopic ends 212 of the two gripper drive components. The two grippers 22 are used to grip the two side walls of the material 100 and to support the bottom wall of the material 100. Thus, before gripping the material 100, the gripper drive component 21 can drive the two grippers 22 away from each other to open the grippers 22. When gripping the material 100, the gripper drive component 21 can drive the two grippers 22 closer together to grip the material 100. In this embodiment, the gripper drive component 21 can be a linear drive mechanism such as a cylinder, hydraulic cylinder, or electric cylinder. It can also be a motor as the drive component, and transmission can be achieved through a gear-rack transmission method.

[0040] Continue to refer to Figures 1-4 The gripper 22 has a groove 221. The grooves 221 of the two grippers 22 are arranged opposite each other, and both grooves 221 are used to accommodate the material 100. So when the material 100 is gripped by the gripper 22, the material 100 is respectively accommodated in the two grooves 221 along the first direction. At this time, the side walls of the material 100 abut against the bottom wall of the groove 221, and the bottom wall of the material 100 abuts against the lower side wall of the groove 221.

[0041] Continue to refer to Figures 1-4 Multiple gripper assemblies 2 and multiple floating assemblies 3 are provided. These gripper assemblies 2 are spaced apart along a second direction, which is perpendicular to the first direction and parallel to the horizontal plane. The second direction is... Figures 1-2 In the CD direction, multiple gripper assemblies 2 are used to clamp the same material 100, and the floating blocks 33 of multiple floating assemblies 3 are used to abut against the top wall of the same material 100, thereby improving the stability when clamping an object 100. It can be applied to materials 100 with a long length, such as the assembly after the light aluminum sheet and the lower plastic are assembled and aligned in this embodiment.

[0042] Alternatively, multiple gripper assemblies 2 and multiple floating assemblies 3 are provided. Multiple gripper assemblies 2 are spaced apart along the first direction. Multiple gripper assemblies 2 are used to clamp different materials 100 respectively. The floating blocks 33 of multiple floating assemblies 3 are used to abut against the top wall of different materials 100 respectively, so that multiple materials 100 can be clamped at the same time.

[0043] In this embodiment, four gripper assemblies 2 and four floating assemblies 3 are provided. The four gripper assemblies 2 and four floating assemblies 3 are arranged in a one-to-one correspondence. Two gripper assemblies 2 and two floating assemblies 3 are set as one group, and the other two gripper assemblies 2 and the other two floating assemblies 3 are set as another group. The two groups of gripper assemblies 2 and floating assemblies 3 are spaced apart along a first direction for gripping different materials 100. In each group, the gripper assembly 2 and another gripper assembly 2 are spaced apart along a second direction so that the two gripper assemblies 2 in the same group are used to grip the same material 100.

[0044] Continue to refer to Figures 1-4 The base 1 includes a frame 11, a lifting drive 12, and a gripper mounting base 13. The lifting drive 12 is used to drive the gripper mounting base 13 to move vertically relative to the frame 11. The gripper assembly 2 is connected to the gripper mounting base 13, and the floating block mounting plate 31 is fixed relative to the gripper mounting base 13. The lifting drive 12 can drive the gripper mounting base 13 to move vertically relative to the frame 11, thereby driving the gripper assembly 2 and the floating assembly 3 to move vertically, so as to complete the gripping and placement of the material 100.

[0045] Optionally, the gripper mounting base 13 includes a mounting block 131 and a first connecting plate 132 and a second connecting plate 133 connected to the mounting block 131. The first connecting plate 132 is fixedly disposed on the mounting block 131, and the second connecting plate 133 is slidably disposed on the mounting block 131 along a first direction. One set of gripper assemblies 2 and floating assemblies 3 is disposed on the first connecting plate 132, and the other set of gripper assemblies 2 and floating assemblies 3 is disposed on the second connecting plate 133. Thus, the position of the second connecting plate 133 relative to the first connecting plate 132 can be adjusted along the first direction to adjust the relative position between the two sets of gripper assemblies 2 and floating assemblies 3.

[0046] Continue to refer to Figures 1-4 The lifting drive component 12 has a fixed end 121 connected to the frame 11 and a telescopic end 122 that can reciprocate vertically relative to the fixed end 121. The gripper mounting base 13 is connected to the telescopic end 122. The lifting drive component 12 can be a linear drive mechanism such as a cylinder, hydraulic cylinder, or electric cylinder, or it can use a motor as the drive component and transmit power through a gear-rack transmission method.

[0047] Continue to refer to Figures 1-4 The base 1 also includes a housing 14 disposed on the gripper mounting base 13. The housing 14 surrounds the lifting drive member 12, thereby providing a certain degree of protection for the lifting drive member 12. Optionally, the telescopic end 122 of the lifting drive member and part of the fixed end 121 of the lifting drive member are disposed inside the housing 14, and the upper part of the housing 14 has an opening 141 for the fixed end 121 of the lifting drive member to pass through.

[0048] In this embodiment, the process of the material gripping mechanism gripping material 100 is as follows:

[0049] First, the material gripping mechanism is moved to directly above the material 100 by a transplanting mechanism or other equipment. The gripper drive 21 drives the two grippers 22 to move away from each other, thus opening the grippers 22. Then, the lifting drive 12 drives the gripper mounting base 13 to descend, thereby lowering the gripper assembly 2 and the floating assembly 3. During the descent, the floating block 33 of the floating assembly 3 first abuts against the upper surface of the material 100. After the gripper assembly 2 has descended to its position, the gripper drive 21 drives the two grippers 22 to move closer together to clamp the material 100. 0. Then, the lifting drive 12 drives the gripper mounting base 13 to rise, thereby driving the gripper assembly 2 and the floating assembly 3 to rise. During the rising process, the lower surface of the material 100 abuts against the side wall of the groove 221 located below, thereby providing support for the lower surface of the material 100. Subsequently, the lifting drive 12 continues to drive the gripper mounting base 13, the gripper assembly 2 and the floating assembly 3 to rise, thereby driving the material 100 to rise. At this time, the material gripping mechanism can continue to move through the transfer mechanism or other equipment, thereby completing the conveying of the material 100.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
