Through the structure of this device, can utilize feeding mechanism to carry out the feed to the lead screw of a large batch, then combine transfer mechanism 2 to shift the lead screw between feeding mechanism 1, length detection mechanism 3 and discharge mechanism 4. The detection work for the length of the screw is realized by means of a distance measuring sensor assembly 31 in the length detecting mechanism 3.

On the basis of the above embodiment, the feeding mechanism comprises a conveyor belt and a feeding frame 11, wherein the conveyor belt is used for feeding to the direction of the length detection mechanism 3, and the screw rod to be detected is placed on the conveyor belt in a mode that the long axis of the screw rod is perpendicular to the feeding direction of the conveyor belt. The feeding frame 11 is arranged at the discharge end of the conveying belt and is used for receiving a screw rod conveyed on the conveying belt; the clamping jaws in the clamping jaw set 21 can move to the upper part of the feeding frame 11 for screw rod grabbing.

The feed rack 11 includes a fixed frame 111 and a lifting frame 112. The fixing frame 111 is fixedly arranged on one side of the conveying belt, a strip groove corresponding to the screw rod is formed in the upper side surface of the fixing frame 111, and the bottom of the groove is an arc surface. The lifting frame 112 comprises at least two hack levers, the hack levers penetrate through the long strip grooves of the fixing frame 111, and the hack levers can ascend or descend in the vertical direction; the upper end surface of the hack lever is provided with an arc-shaped groove corresponding to the screw rod; when the lifting frame 112 is lifted, the upper end surface of the frame rod is positioned right above the long strip groove of the fixing frame 111. A feeding cylinder is provided below the fixing frame 111, and a movable end of the feeding cylinder is connected with the lifting frame 112 for driving the lifting frame 112 to rise or fall.

To facilitate the gripping of the jaws of the jaw set 21 on a single screw, it is not sufficient if the screw is simply placed on a conveyor. The solution therefore provides a structure of the feeding frame 11 at the end of the conveyor belt. The lifting frame 112 adopts a feeding cylinder to provide lifting power. In the initial state, the upper end surface of the lifting frame 112 coincides with the groove position of the fixing frame 111 or is lower than the groove position of the fixing frame 111. A transition plane structure is arranged between the end faces of the fixing frame 111 and the conveying belt, and the screw rod is conveyed by the conveying belt and falls into the groove of the fixing frame 111 after passing through the transition plane structure by inertia. The elevator 112 then lifts and the clamping bar lifts the tubular screw, thereby facilitating the clamping of the tubular screw by the clamping jaws.

On the basis of the above embodiment, the jaw set 21 of the transfer mechanism 2 comprises several jaws; the transfer mechanism 2 further includes a traversing mechanism 22 and a longitudinally moving mechanism 23. Wherein the transverse moving mechanism 22 can drive the clamping jaw set 21 to move in the transverse direction, and the transverse direction of the transverse moving mechanism 22 is parallel to the feeding direction of the feeding mechanism 1; the longitudinal moving mechanism 23 can drive the clamping jaw set 21 to move in the longitudinal direction.

The clamping jaw of the clamping jaw group 21 is a pneumatic or electric clamping jaw, each clamping jaw comprises two oppositely arranged clamping jaw bodies, one opposite side of each clamping jaw body is correspondingly provided with a groove, and when the two clamping jaw bodies are combined, the grooves are spliced into clamping notches corresponding to the tubular screw rod. The two claw bodies are separated in the transverse direction and then combined to complete the grabbing action. The clamping jaw set 21 further comprises a clamping jaw support, a plurality of clamping jaw installation positions are arranged on the clamping jaw support in a linear array distribution mode, and the distribution direction of the clamping jaw installation positions is parallel to the feeding direction of the feeding mechanism 1.

The jaw support includes an upper frame and a lower frame. The upper frame is connected with a traversing mechanism 22, and can be driven by the traversing mechanism to carry out traversing: the lower frame is in sliding connection with the upper frame in the vertical direction, and the lower frame is connected with a longitudinal moving mechanism 23, and can be driven by the longitudinal moving mechanism 23 to move in the vertical direction, and a clamping jaw mounting position is arranged on the lower frame. The transverse moving mechanism 22 adopts a transversely arranged air cylinder, so that the aim of driving the upper frame of the clamping jaw support to transversely reciprocate is fulfilled. The vertical movement mechanism 23 is also a cylinder, and its movable end drives the upper frame to move up and down.

Since the present solution involves the transfer of the screw between the feeding mechanism 2, the length detection mechanism 3 and the discharge mechanism 4, it is necessary that the jaws of the jaw set 21 are able to perform movements in both the transverse and longitudinal directions. The traversing mechanism 21 drives the whole clamping jaw support to transversely reciprocate, so that the clamping jaws can transfer the screw rods one by one among the mechanisms after grabbing from the feeding frame 11 until the screw rods move to the position of the discharging mechanism 4.

On the basis of the above embodiment, referring to fig. 3 and 4, the length detecting mechanism 3 further includes a first baffle 32, the first baffle 32 being fixedly disposed on the upper side of the base, and being located on both sides of the jaw set 21 with the distance measuring sensor assembly 31, respectively; a sliding rail 33 is correspondingly arranged on the first baffle 32, the sliding rail 33 is fixedly arranged on the base station, the sliding rail and the ranging sensing assembly 31 are positioned on the same side, and the ranging sensing assembly 31 is in sliding connection with the sliding rail 33. The length detection mechanism 3 further comprises a distance measurement driving piece, wherein the distance measurement driving piece is an air cylinder or an electric push rod, the movable end of the distance measurement driving piece is connected with the distance measurement sensing component 31, and the distance measurement sensing component 31 can be driven to slide along the sliding rail 33.

The ranging sensor assembly 31 specifically includes a sliding table 311, a top block 312, a sensor mounting position 313, and a laser ranging sensor. The sliding table 311 is slidably connected to the sliding rail 33, and can slide along the sliding rail 33. The top block 312 is fixedly arranged on the sliding table 311. The sensor mounting position 313 is arranged on one side of the sliding table 311 and is used for mounting a laser ranging sensor.

Through this structure, when carrying out lead screw length detection, the clamping jaw puts the lead screw on the grudging post of corresponding position, then range finding driver drives slip table 311 and removes towards the lead screw on slide rail 311, promotes the lead screw tip through kicking block 312, pushes up the lead screw on first baffle 32. In order to determine the thrust amplitude of the top block 312, as a further option, a pressure sensor may be provided at the position of the top block 312 to determine the push of the screw in place. In the process, the sliding table 311 drives the laser ranging sensor to move, and the measured value of the length of the screw rod is obtained according to the feedback of the laser ranging sensor.

On the basis of the above embodiment, two modes of setting the laser ranging sensor can be adopted, one is that the laser ranging sensor is set towards the direction of the first baffle 32, and the laser ranging sensor detects the distance between the baffle 32 and the laser ranging sensor and is used as a reference whether the length of the screw rod meets the standard.

In another implementation manner, a plurality of connecting holes 331 or long mounting grooves are formed on one side of the sliding rail 33 and are used for connecting the second baffle; the transmitting end of the laser ranging sensor is arranged towards the second baffle. The second shutter is installed by selecting an appropriate connection hole 331. And then, acquiring whether the screw rod meets the length design requirement or not according to the distance feedback between the laser ranging sensor and the second baffle. When the screw rod is used as the standard length, the laser ranging sensor feeds back that the distance between the laser ranging sensor and the second baffle is a, and whether the distance is larger than a or smaller than a, the current detected screw rod length is not in accordance with the requirement.

The advantage of changing the connecting hole 331 into the strip-shaped mounting groove is that if the screw rod to be detected is changed, then the displacement distance of the sliding table 311 is changed, and the device can be continuously used by adaptively adjusting the position of the second baffle on the sliding rail 33 to keep the distance between the second baffle and the laser ranging sensor, without correcting the feedback of the laser ranging sensor from the aspect of an electric control system.

On the basis of the above embodiment, the discharging mechanism 4 includes the receiving tray 41, and the receiving tray 41 is disposed obliquely with its high horizontal end near the length detecting mechanism 3. A material distributing driving piece is arranged in connection with the material receiving tray 41, and the material distributing driving piece can drive the material receiving tray 41 to move in the vertical direction or the horizontal direction. This scheme adopts the structure form that connects the charging tray 41 to connect horizontal track, divides the material driving piece to set up in the horizontal one side that connects the charging tray 41, and when the lead screw is suitable, divides the material driving piece to drive and connects the charging tray 41 to be in first working position, and the clamping jaw can be with the lead screw of pressing from both sides the direct placement of taking on connecing the charging tray 41.
