the utility model provides an automatic collating unit for nailing of car parcel layer, includes the casing, twists the subassembly, the component assembly is moved to the screw, sets up a plurality of permutation hole on the casing, arranges downthehole respectively to set up and twists the subassembly, and the component assembly sets up in the casing, and the component assembly is twisted the subassembly for every and is provided the moment of torsion. In order to fix the wrapping layer on the mounting frame, screws need to be screwed at a plurality of positions, a plurality of arrangement holes are formed in the shell and used for placing the screws, the screws are arranged in the holes in sequence, the shell is abutted to the surface of the wrapping layer, then, a screwing force is input into the component force assembly, the component force assembly drives each screwing assembly to rotate, each screwing assembly drives the screws to be screwed into the screw holes of the wrapping layer and the mounting frame, the screws in a larger range are uniformly screwed, and therefore screwing quality of the screws in the region is consistent, and mutual influence cannot be generated.
Furthermore, spring choke structures formed by reeds are arranged in the arrangement holes. After the screw is put into the arrangement hole, a corresponding position holding structure is needed, otherwise, the screw falls out from the arrangement hole before being inserted into the screw hole, and the traditional magnetic type screw positioning mode can not be conveniently used in the structure, because the screw is uniformly screwed by the mode of a plurality of aligned holes, the number of the screws is increased, however, the installation depth of each screw in the aligned holes is not uniform, because the wrapping layer often has a curved surface position, and the surface of the shell facing the wrapping layer can not know the curved surface shape in advance, therefore, the installation position of each screw can be adapted only by adjusting the depth of the screw in the arrangement hole, and the choke structure formed by the reeds, the screw head can be allowed to push the reed open under larger stress, and after the external force is lost, the screw head and the body are tightly propped by the reed to keep the position unchanged, and the screwing assembly above is waited to apply force to the screw head.
Furthermore, three or more groups of reeds are arranged in each arrangement hole along the depth direction of the hole, and at least three reeds are uniformly distributed on the circumference of each group of reeds on a plane vertical to the axis of the arrangement hole. The reed is used for maintaining the posture of the screw before screwing in the screw hole, the screw is pushed into the arrangement hole, at least two groups of reeds are attached to the body part of the screw before screwing, radial support is provided for the screw like a sliding bearing, the reeds can be forced to deform, the arrangement hole is enlarged so as to enable the head part of the screw to pass through, at least three reeds are uniformly distributed on the circumference of each layer of reeds to support the screw, the radial support is uniform and stable, the initial deformation of the reeds is easy to occur, and therefore when the screw hole is slightly inclined, the rod end part of the screw can slightly shake to be inserted into the screw hole in an adaptive mode.

Further, the spring is a constant force spring. The constant force spring is characterized in that the elasticity of the constant force spring is not changed along with the deformation stroke, the constant force spring is used in the screwing assembly, the hexagonal head and the screw can have constant contact force and does not change along with the curved surface of the installation position, a common constant force spring is a spring and is similar to a tape measure structure, when the constant force spring is used in the application, one end of the spring is required to be fixed with the end part of the first connecting rod, and then the scroll part is arranged in an accommodating structure of the second connecting rod.
Further, the component force assembly comprises an input shaft, a component force unit and a plurality of output shafts, the output shafts are respectively in transmission connection with the relay shafts, and the component force unit distributes torque input by the input shafts according to resisting torque on each output shaft: the greater the resistive torque on the output shaft, the smaller the proportion of torque achieved. The external screw screwing power is loaded on the first input shaft, the input torque on the input shaft is distributed on the multi-output shaft through the plurality of component force units, the distributed torque is smaller when the resisting torque on the output shaft is larger, in consideration of the consistent screwing force of the screws, the screws at different positions have different resistance rising curves according to the screwing amount, if the initial screwing force is uniformly distributed, the screws at some positions are screwed tightly and some are loosened, which is not expected, therefore, the component force units transfer more torque to the positions with smaller screw screwing resistance, after the positions with smaller screwing resistance are screwed for a certain amount, the resisting torque can rise until the screwing resistance is approximately equal to the screwing resistance of the surrounding screws, namely, the screwing tightness degree is the same, the matching time is a more uniform screwing period, and therefore, the screw screwing quality in the range can be ensured, mutual screwing interference is not generated, and the long-term use of the fastening structure is facilitated.

After zero shaft input torque, two output shafts are respectively a first output shaft and a second output shaft,
when the drag torque on the first output shaft is large: the second output gear has large rotation resistance, so that the rotation motion of the zero axis gear is mostly used for driving the junction gear to rotate and revolve, the revolution of the junction gear is the revolution of the component gear, the second output assembly is driven to rotate when the component gear revolves, and most of the rotation motion is output from the second output shaft;
when the resistance on the second output shaft is large: the revolution resistance of the component gear and the connecting frame is very large, so that most of the rotation of the zero axis gear is transmitted to the second output gear through the junction gear, so as to drive the second output shaft to output, and at the moment, the junction gear only rotates and does not revolve;
the force component units are combined, the first-stage first output shaft and the second-stage second output shaft are respectively used as zero shafts of the subsequent force component units, single rotary motion can be distributed to multiple positions for rotary output, the distribution proportion is determined according to screw resistance torque at each position, a uniform screwing process is achieved, after the force component units are combined, the first-stage zero shaft is an integral input shaft of the force component assembly, and the first output shaft and the second output shaft of the last-stage multiple force component units are multiple output shafts of the force component assembly.
