DETAILED DESCRIPTION

[0022] The technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model.

[0023] Embodiment one: the utility model provides a kind of clamping mechanical hand for injection molding equipment, including device main body 100, device main body 100 includes mechanical hand body 113, mechanical hand body 113 includes driving assembly 114, driving assembly 114 includes movable slot 118, two movable blocks 115 are slidably connected in movable slot 118, first clamping jaw 116 and second clamping jaw 117 are respectively installed on movable block 115, and the clamping or loosening of clamping jaw is realized by the mutual approach or away of movable block 115;The clamping surface of first clamping jaw 116 and second clamping jaw 117 is all provided with flexible clamping part 119, and flexible clamping part 119 includes base 120 and is formed by multiple independently telescopic buffer telescopic column 121, and the end of buffer telescopic column 121 is hemispherical, to adapt to the product of irregular shape, and reduce the damage to product when clamping.

[0024] When it is necessary to clamp the injection molded product, the two movable blocks 115 in the movable slot 118 within the drive assembly 114 will move closer or farther away from each other according to the control signal, and the movement of the movable blocks 115 drives the first clamp jaw 116 and the second clamp jaw 117 mounted thereon to complete the clamping or loosening action. When the clamp jaws contact the product, the buffer telescopic column 121 will extend or retract according to the shape and size of the product to adapt to the irregular product surface. At the same time, the buffer telescopic column 121 provides a buffering effect, which can absorb the impact force generated during clamping, thereby protecting the product from damage. Further, the end of the buffer telescopic column 121 is designed as a hemisphere, which can better adapt to the surface of the product, reducing friction and damage during clamping.

[0025] Embodiment two:

[0026] Compared with embodiment one, embodiment two makes more in-depth innovation in the structure of the buffer telescopic column 121 and increases the multi-dimensional motion control capability, further improving the flexibility and applicability of the mechanical hand.

[0027] Specifically, the buffer telescopic column 121 is composed of an external sleeve 122, an internal plug column 123, and a buffer spring 124 located between the two. When the clamp jaw contacts the product, the internal plug column 123 will slide within the external sleeve 122, while compressing the buffer spring 124. This mechanism provides additional buffering effect, further reducing the impact and damage to the product during clamping.

[0028] In addition, the device body 100 also integrates multi-dimensional moving parts 110, lifting parts 111 and rotating parts 112. These advanced functional parts work together to give the mechanical hand body 113 unprecedented flexibility and precision. The multi-dimensional moving parts 110 realize precise positioning through a motor-driven screw 125 and a driving block 126 moving along it. The outer surface of the junction between the driving block 126 and the screw 125 is additionally provided with a ring-shaped cleaning brush 127. This design can automatically clean the debris and dirt on the surface of the screw 125 when the driving block 126 moves, ensuring the long-term stability and reliability of the transmission system.

[0029] In order to enhance the maintainability and flexibility, the movable block 115 and the first clamp jaw 116 and the second clamp jaw 117 adopt a detachable connection method, such as bolt connection or buckle connection. This design allows the operator to quickly replace or adjust the type of clamp jaw according to the clamping needs of different products, thereby greatly improving production efficiency and the versatility of the equipment.

[0030] More noteworthy, the flexible clamping component 119 also integrates a pressure sensor inside the buffer telescopic column 121, which is an intelligent design that can monitor the clamping force of the clamping jaw on the product in real time. When the clamping force exceeds the preset safety threshold, the control system can immediately respond and stop the movement of the mechanical hand, effectively preventing excessive extrusion or damage to the product, further improving the safety and reliability of the clamping operation.

[0031] Finally, it should be pointed out that: first, in the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "installation", "connection", "connection" should be broadly understood, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
