As shown in fig. 2, the middle of each cross bar of the first movable frame is further provided with a fixed jaw mechanism 24, and two sides of the fixed jaw mechanism 24 on each cross bar are further provided with a movable jaw mechanism 60.

The first driving motor 31 is in transmission connection with the first lead screw 32, and the first lead screw 32 is in spiral connection with the first type of screw, so that the rotation of the first driving motor 31 can be converted into the rotation of the first lead screw 32 and the translation of the first type of screw, and the translation of the first movable frame is realized.

As shown in fig. 5, preferably, the first lead screw 32 includes a first lead screw portion 321 and a second lead screw portion 322 with opposite turning directions, the first type of screw includes a first screw 33 and a second screw 34 with opposite internal threads and turning directions, the first lead screw portion 321 is in screw connection with the first screw 33, the first screw 33 is fixedly connected with the first cross bar 21 of the first movable frame, the second lead screw portion 322 is in screw connection with the second screw 34, the second screw 34 is fixedly connected with the second cross bar 22 of the first movable frame, and the movable clamping jaw mechanisms 60 are respectively connected to the first cross bar 21 and the second cross bar 22 in a translational manner.

That is, the first rail 21 and the second rail 22 move the same distance after a certain number of rotations. Furthermore, a movable clamping jaw mechanism 60, a fixed clamping jaw mechanism 24 and a movable clamping jaw mechanism 60 are sequentially arranged on the first cross rod 21 and the second cross rod 22 along the length direction, the fixed clamping jaw mechanism 24 is fixedly connected with the first cross rod 21 and the second cross rod 22 respectively, and the movable clamping jaw mechanism 60 is slidably mounted on the first cross rod 21 and the second cross rod 22.

Fig. 6 is a schematic structural diagram of the second frame driving device in the above-mentioned reinforcing mesh grabbing device. As shown in fig. 2 and 6, preferably, the second frame driving device 50 includes a second driving motor 51 installed on the main frame 11 and a second transmission mechanism connected to the second driving motor 51, the second transmission mechanism includes a second lead screw 52 connected to the second driving motor 51 and a second kind of screw nut spirally connected to the second lead screw 52, and the second lead screw 52 is installed on the first movable frame through a second kind of lead screw bracket 55.

The first lead screw 32 and the second lead screw 52 are preferably vertically disposed, and correspondingly, the first cross bar 21 and the second cross bar 22 of the first movable frame are also vertically disposed with respect to the first lead screw 32. The first and second cross bars 21 and 22 of the first moving frame and the first and second driving levers 41 and 42 of the second moving frame are also vertically disposed.

The second driving motor 51 is in transmission connection with the second lead screw 52, and the second lead screw 52 is in screw connection with the second type of screw nut, so that the rotation of the second driving motor 51 can be converted into the rotation of the second lead screw 52 and the translation of the second type of screw nut, and the translation of the second movable frame is realized.

As shown in fig. 6, preferably, the second lead screw 52 includes a third lead screw portion 521 and a fourth lead screw portion 522 with opposite rotation directions, the second type of nut includes a third nut 53 and a fourth nut 54 with opposite internal threads and rotation directions, the third lead screw portion 521 is spirally connected with the third nut 53, the third nut 53 is fixedly connected with the first transmission rod 41 of the second movable frame, the fourth lead screw portion 522 is spirally connected with the fourth nut 54, and the fourth nut 54 is fixedly connected with the second transmission rod 42 of the second movable frame.

Specifically, the first transmission rod 41 is connected to one movable clamping jaw mechanism 60 on the first cross bar 21 and is also connected to one movable clamping jaw mechanism 60 on the second cross bar 22, the two movable clamping jaw mechanisms 60 are both located at one side of the two fixed clamping jaw mechanisms 24, and the first transmission rod 41 can drive the two movable clamping jaw mechanisms 60 to respectively move synchronously on the corresponding cross bars; the second transmission rod 42 is connected to a movable clamping jaw mechanism 60 on the first cross bar 21 and also connected to a movable clamping jaw mechanism 60 on the second cross bar 22, the two movable clamping jaw mechanisms 60 are located at one side of the two fixed clamping jaw mechanisms 24, and the second transmission rod 42 can drive the two movable clamping jaw mechanisms 60 to synchronously move on the corresponding cross bars respectively.

Because there may be a deviation in processing the mesh transverse rib 99 of the steel mesh 90, the second frame driving device 50 is used to drive the corresponding movable clamping jaw mechanism 60, and all the movable clamping jaw mechanisms 60 cannot be aligned to the corresponding mesh transverse rib 99. For example, the distances between the mesh-sheet transverse ribs 99 corresponding to the movable clamping jaw mechanisms 60 on both sides of the fixed clamping jaw mechanism 24 and the mesh-sheet transverse ribs 99 corresponding to the fixed clamping jaw mechanism 24 are 92 cm and 94 cm, respectively. Since the first transmission rod 41 and the second transmission rod 42 are moved at opposite and equal distances, it is difficult to grasp the mesh sheet 90 in such a situation, and the following solution is adopted to solve the problem.

Fig. 3 is a schematic perspective view of the movable clamping jaw assembly in the above-mentioned steel mesh gripping device; fig. 4 is a rear view of the movable clamping jaw assembly in the reinforcing mesh grabbing device. As shown in fig. 3 and 4, preferably, the movable jaw mechanism 60 includes a jaw driving member 62, the jaw is mounted on an output end of the jaw driving member 62, the jaw driving member 62 is movably disposed relative to the jaw mounting member 61, and a direction in which the jaw driving member 62 drives the jaw to move relative to the jaw mounting member 61 is a direction in which the jaw driving member 62 drives the jaw to move.

Specifically, in the present embodiment, the jaw driving member 62 may employ a jaw cylinder. The clamping jaw cylinder has two power take-off 621, and each power take-off 621 is connected with a clamping jaw monomer respectively. The two clamping jaw single bodies jointly exert an upward acting force on the local part of the reinforcing steel mesh sheet 90 positioned between the clamping jaw single bodies. In this embodiment, the two jaw single bodies are driven to move closer to or away from each other by the jaw driving member 62 in the horizontal direction of fig. 2, so that the moving direction of the jaw driving member 62 relative to the jaw mounting member 61 is also the left-right direction in the drawing. More specifically, the jaw cylinder may be mounted to the jaw mount 61 via a cylinder guide. The main frame 11 may also be provided with a plurality of crossed longitudinal beams 13 and a plurality of crossed transverse beams 14, and solenoid valve assemblies 15 may be installed at the crossing points of the longitudinal beams 13 and the transverse beams 14 to control the opening and closing of the gripper cylinders. In further implementations, solenoid valves may also be provided at the intersections of the stringers 13 and cross beams 14 within the active area of each movable gripper mechanism 60 to control the opening and closing of the corresponding gripper cylinders. In addition, a device mounting plate 16 is fixedly connected to a cross point located at the middle of the main frame 11 among the cross points of the longitudinal beams 13 and the cross beams 14, and the device mounting plate 16 is connected to an external driving device, so that the reinforcing mesh grasping device can be moved by the external driving device.

When the steel bar net piece 90 is lifted by the clamping jaw mechanism, if the position of the net piece transverse rib 99 does not completely correspond to the clamping jaw cylinder, the clamping jaw is opened, the opening shape with a small upper part and a large lower part is formed, the clamping jaw driving piece 62 can be pushed to move horizontally, so that the center of the clamping jaw driving piece 62 can be just right opposite to the net piece transverse rib 99, the clamping jaw driving piece 62 drives the clamping jaw to be folded, the net piece transverse rib 99 is just between the two clamping jaws, and the steel bar net piece 90 is conveniently and accurately lifted.

Or even if the clamping jaw driving piece 62 does not horizontally move in place in the descending process, in the process that the clamping jaws are folded from the opening process, component force is generated on the acting force of the transverse rib 99 of the net piece in the horizontal direction, and the counteracting force pushes the clamping jaws and the clamping jaw cylinder to reversely and horizontally move so as to be positioned right opposite to the longitudinal rib 98 of the net piece. In the case of the above-mentioned distances of 92 cm and 94 cm, respectively, the movable jaw mechanisms 60 on both sides of the fixed jaw mechanism 24 can be made to be 93 cm from the fixed jaw mechanism 24, the remaining 1 cm being compensated by the relative movement of the jaw drive 62 with respect to the jaw mount 61.

Moreover, the movement of the jaw actuator 62 relative to the jaw mount 61 may not only be used to compensate for the non-uniform spacing of the web transverse ribs 99. If the transverse mesh sheet rib 99 below the movable clamping jaw mechanism 60 is not completely perpendicular to the longitudinal mesh sheet rib 98, that is, the transverse mesh sheet rib 99 clamped by the fixed clamping jaw mechanism 24 is not parallel to one transverse mesh sheet rib 99 clamped by the two movable clamping jaw mechanisms 60. The fixed jaw mechanism 60 may be aligned with the underlying web cross rib 99, while the two movable jaw mechanisms 60 may not be aligned with the underlying web cross rib 99. For example, when the distance between the position of one of the transverse mesh ribs 99 clamped by the two movable jaw mechanisms 60 and the transverse mesh rib 99 under the fixed jaw mechanism 24 is 92 cm and 94 cm, respectively, the distance can be compensated by the movement of the jaw driver 62 relative to the jaw mounting member 61.

As shown in fig. 3, the clamping jaw preferably includes a hook-shaped clamping jaw single body 64, and the hook-shaped clamping jaw single body 64 has a horizontal portion 641, and the horizontal portion 641 is used for applying an upward force to the grasped mesh sheet 90.

In the present embodiment, two hook-shaped gripper monomers 64 are respectively mounted on two power take-offs 621 of the gripper cylinder. The hook-shaped jaw unit 64 includes a vertical portion 642 and a horizontal portion 641. Specifically, the vertical portion 642 and the horizontal portion 641 are straight bars, and the vertical portion 642 and the horizontal portion 641 are vertically disposed, that is, the hook-shaped clamping jaw unit 64 is L-shaped. The two horizontal portions 641 of the two hook-shaped jaw units 64 that are disposed opposite to each other in the same movable jaw mechanism 60 are disposed alternately in the longitudinal direction of the mesh cross rib 99. In another embodiment, the horizontal portion 641 may have an upwardly open arc shape or a V shape, and may be shaped to lift the mesh sheet cross rib 99 by directly applying an upward force. In addition, the vertical portion 642 may also be an arc shape such as a bracket shape, not limited to the shape of a straight bar.

By providing the hook-shaped clamping jaw single body 64 with the horizontal portion 641, the horizontal portion 641 can bear the weight of the steel mesh sheet 90, and when the steel mesh sheet 90 is in a uniform linear motion state or a static state, no horizontal friction force is generated between the two. The moment generated by the mesh cross rib 99 relative to the swing center of the power output member 621 of the jaw driving member 62 is only the product of the horizontal distance of the portion of the mesh cross rib 99 relative to the swing center and the gravity shared by the portion of the mesh cross rib 99. Compared with various schemes of generating friction force by clamping the reinforcing steel bars and balancing the reinforcing steel bar mesh piece 90 by using the friction force, the output acting force of the clamping jaw air cylinder is obviously reduced. When the clamping jaw cylinder is in the clamping state, the two hook-shaped clamping jaw single bodies 64 are matched, so that the two horizontal portions 641 are located below the mesh transverse bar 99, and the local part of the reinforcing steel mesh 90 can be prevented from shaking left and right on the horizontal portion 641.

As shown in fig. 3, the jaw mount 61 preferably includes a mounting base 611, a spring mount fixedly connected to the mounting base 611, and a horizontal resilient member 69 connecting the spring mount and the jaw driver 62, the horizontal resilient member 69 being mounted in a direction in which the jaw driver 62 moves relative to the jaw mount 61.

The horizontal elastic member 69, in this embodiment, may be a cylindrical helical extension spring, one end of which is connected to the side wall of the clamping jaw cylinder, and the other end of which is connected to the spring mounting member. It should be noted that since all lines of the spring-like member are shown, the corresponding areas in the figure may be black, and therefore, the horizontal elastic member 69 is shown only as a column in fig. 3. In another implementation, the horizontal elastic member 69 may also be a cylindrical helical compression spring, the cylindrical helical compression spring is sleeved on a spring guide post, two ends of the cylindrical helical compression spring are respectively abutted against the clamping jaw cylinder and the spring mounting plate 612, and the spring guide post may also be used as a guide rail for the sliding of the clamping jaw cylinder.

In this embodiment, the spring mounting members are spring mounting plates 612 respectively disposed on two opposite sides of the mounting base 611, and an upper end surface and a lower end surface of the spring mounting plates 612 can respectively extend out of the connecting column 613 to be connected with the hooks at the ends of the cylindrical helical tension spring. In further implementations, the connection post 613 may also be disposed directly on the mounting base 611 such that the connection post 613 is perpendicular to the mounting base 611.

In this embodiment, every horizontal elastic component 69 is all arranged horizontally, and at the four corners position of clamping jaw cylinder, connect a cylindrical helical extension spring respectively and be connected with spring mounting plate 612, sets up like this, and the four corners position from the clamping jaw cylinder all can exert the effort, can improve the stability of clamping jaw cylinder. In fact, in other implementations, a cylindrical helical extension spring may be provided on each side of the middle of the gripper cylinder to apply a force to the gripper cylinder in the direction of movement of the gripper cylinder, but this may not be as stable as the above arrangement. However, considering that the gripper cylinder is already slidably mounted on the mounting base 611 via the cylinder rail, the cylinder rail can be used to bear the corresponding torque, and therefore, by providing only one spring on each side, even if the forces of the horizontal elastic members 69 are not collinear, no significant negative effect will be produced. In addition, the horizontal elastic member 69, as described above, does not absolutely limit that each elastic member such as a cylindrical coil tension spring or a cylindrical coil compression spring must be horizontally arranged as long as the resultant force of the elastic member to the chuck cylinder is horizontal or substantially horizontal.

By arranging the horizontal elastic piece 69 in the direction of the clamping jaw driving piece 62 moving relative to the clamping jaw mounting piece 61, the clamping jaw driving piece 62 can restore to the original position under the action of the horizontal elastic piece 69 after releasing the steel bar mesh sheet 90, so that the clamping jaw cylinder and the clamping jaw mounting piece 61 can be kept in a relatively uniform position after each time of grabbing the steel bar mesh sheet 90, and each grabbing operation is facilitated.

As shown in fig. 4, preferably, the movable clamping jaw mechanism 60 further includes a pressing block 65 and a sensor, the pressing block 65 is movably mounted on the clamping jaw mounting member 61 along the vertical direction, the sensor is mounted on the clamping jaw mounting member 61, the pressing block 65 is fixedly connected with the sensing member 66, and the sensor is used for sensing the sensing member 66 when the sensing member 66 and the pressing block 65 move together.

Specifically, the width of the pressing block 65, i.e., the dimension in the horizontal plane perpendicular to the mesh-sheet transverse rib 99, is less than or equal to the opening dimension of the two hook-shaped jaw monomers 64 when the two hook-shaped jaw monomers are opened. Preferably, the pressing block 65 may be located at the middle of the opening in the width direction, so that when the pressing block 65 is pushed up by the web transverse rib 99, it can be said that the web transverse rib 99 is also located at a position suitable for being lifted by the two hook-shaped jaw monomers 64. If the pressing block 65 is not jacked up by the mesh transverse rib 99 along with the descending of the steel mesh gripping device, it indicates that although the mesh transverse rib 99 is located in the area right below the opening, the horizontal movement distance of the clamping jaw driving piece 62 may be too large, and exceeds the stroke capable of moving relative to the clamping jaw mounting piece 61; or the mesh transverse ribs 99 are not within the above-mentioned opening range; or the height of the web cross rib 99 is too low, even if the jaw driving member 62 is lowered to the lowest position, the horizontal portion 641 of the hook-shaped jaw unit 64 cannot catch the web cross rib 99.

In addition, the pressing block 65 is movably connected with a linear bearing 653 fixedly installed on the mounting base 611 through a pressing guide rod 651, and a pressing spring 652 is further sleeved on the pressing guide rod 651, specifically, the pressing spring 652 may be a cylindrical helical compression spring. Based on the above-mentioned description of the method of representation of the horizontal spring 69, the entire contour of the compression spring 652 is not shown in detail in fig. 4 either. The pressing spring 652 is arranged, so that the pressing force provided by the reinforcing steel bar mesh 90 to the production equipment in the subsequent link can be conveniently controlled by the pressing block 65. In addition, in the process that the reinforcing steel bar net piece 90 is conveyed, the pressing block 65 can also press the net piece transverse rib 99 downwards, the position of the net piece transverse rib 99 is limited together with the horizontal part 641 and the vertical part 642 of the two hook-shaped clamping jaw single bodies 64, and the shaking of the reinforcing steel bar net piece 90 in the conveying process is reduced.

In the present embodiment, the sensing member 66 has a fixing plate 661 for mounting the sensing member 66 to the pressing block 65, and a sensing plate 662 for being sensed by the sensing member 66, the sensing plate 662 being located above the fixing plate 661. More specifically, the fixing plate 661 is provided with a coupling hole to be fixed to the pressing block 65 by a screw coupling member such as a bolt or a screw. Further, the connecting hole may be a waist-shaped hole extending in a vertical direction so as to adjust the relative position of the sensing member 66 and the pressing block 65. The present embodiment may provide two inductors, a first inductor 67 and a second inductor 68, where the first inductor 67 is located below the second inductor 68 and both are located on the back of the mounting base 611. The sensor can be a correlation infrared sensor or a correlation laser sensor, or a proximity switch or a reflection infrared sensor or a reflection laser sensor, and when the sensing piece 66 moves to the front of the sensor, the sensor can be triggered; or the sensor may be a travel switch if space conditions permit.

Generally, when the pressing block 65 presses against the mesh of the rebar mesh 90, the upper portion of the sensing plate 662, which may be located in front of the second sensor 68, is sensed by the second sensor 68. If the reinforcing bar mesh grabbing device continues to move downwards, and the pressing block 65 moves upwards relative to the clamping jaw mounting piece 61, the sensing plate 662 can also continue to ascend and be sensed by the first sensor 67.

Through setting up compact heap 65 and response piece 66 fixed connection to when reinforcing bar net piece grabbing device descends, utilize compact heap 65 and the horizontal muscle 99 contact of net piece earlier, follow that decline process response piece 66 rises for clamping jaw installed part 61, are sensed by the inductor, have the horizontal muscle 99 of net piece in order to ensure activity clamping jaw mechanism 60 below, so that snatch by activity clamping jaw mechanism 60.

The action principle of the steel mesh grabbing device of the embodiment is as follows:

when the reinforcing mesh sheet 90 needs to be grabbed, the reinforcing mesh sheet grabbing device is firstly moved (the mechanism for moving the reinforcing mesh sheet grabbing device does not belong to the scope discussed in the application), so that the fixed clamping jaw mechanism 24 is located right above the corresponding mesh sheet transverse rib 99. Then, the first driving motor 31 rotates to drive the first lead screw to rotate, so that the first screw nut 33 and the second screw nut 34 which are in screw connection with the first lead screw translate reversely at a constant speed, the distance between the first cross rod 21 and the second cross rod 22 is changed, and further the distance between the corresponding fixed clamping jaw mechanism 24 and the corresponding movable clamping jaw mechanism 60 is changed, so that the adjustment is performed until the fixed clamping jaw mechanism 24 and the movable clamping jaw mechanism 60 do not interfere with the mesh longitudinal rib 98 after descending.

Then, the second driving motor 51 rotates to drive the second lead screw to rotate, so that the third screw nut 53 and the fourth screw nut 54 which are spirally connected with the second lead screw translate reversely and equally, the distance between the first transmission rod 41 and the second transmission rod 42 is changed, and the distance between the movable clamping jaw mechanisms 60 on the two sides of the fixed clamping jaw mechanism 24 is further changed. When the distances between the mesh sheet transverse ribs 99 below the movable clamping jaw mechanisms 60 on the two sides of the fixed clamping jaw mechanism 24 and the mesh sheet transverse ribs 99 below the fixed clamping jaw mechanism 24 are different, for example, the distances are respectively 92 cm and 94 cm, the movable clamping jaw mechanisms 60 on the two sides can be adjusted to be 93 cm away from the movable clamping jaw mechanisms 60, and the remaining 1 cm is compensated by the relative movement of the clamping jaw driving piece 62 relative to the clamping jaw mounting piece 61. Alternatively, if the one-sided travel of the jaw drive 62 relative to the jaw mount 61 can be up to 2 cm, the distance can also be adjusted to 92 cm or 94 cm. In addition, the transverse mesh-sheet rib 99 under the movable clamping jaw mechanism 60 is not completely perpendicular to the longitudinal mesh-sheet rib 98, for example, when the distance between the position of one longitudinal mesh-sheet rib 98 clamped by the two movable clamping jaw mechanisms 60 and the transverse mesh-sheet rib 99 under the fixed clamping jaw mechanism 24 is 92 cm and 94 cm, respectively, the distance can be compensated by the movement of the clamping jaw driving piece 62 relative to the clamping jaw mounting piece 61.

Then, the jaw driving member 62 drives the two hook-shaped jaw monomers 64 to be in an open state, the reinforcing steel mesh grabbing device descends, and the pressing block 65 and the mesh transverse rib 99 start to contact. The width of the hold-down block 65 is less than or equal to the size of the opening of the two hook-shaped jaw single bodies 64 when the two hook-shaped jaw single bodies are opened. Therefore, as the reinforcing mesh gripping device is lowered, the pressing block 65 is raised relative to the jaw mounting member 61, and the sensing member 66 is also raised together with the pressing block 65. The sensing member 66 is first sensed by the first sensor 67, indicating that the web cross bar 99 is located below the movable jaw mechanism 60. The sensor 66 then continues to rise, and when the upper end of the sensor 66 is sensed by the second sensor 68, the sensor 66 is shown to have reached the uppermost operative position relative to the jaw mount 61, and correspondingly, the lifted mesh cross bar 99 is shown to have reached the uppermost operative position.

For all of the movable jaw mechanisms 60, if the sensing member 66 is sensed by the first sensor 67 but not by the second sensor 68, it indicates that the lifted mesh transverse ribs 99 are at the proper height to be lifted. If each sensing member 66 is sensed by the first sensor 67, and some sensing members 66 are sensed by the second sensor 68, it indicates that some mesh transverse ribs 99 are at the highest position within the acceptable height range. If some of the sensing members 66 are sensed by the second sensor 68 but not by the first sensor 67, it is indicated that the web cross bar 99 under these non-sensed sensing members 66 is either too low in height to be hooked by the hook-shaped jaw members 64 or is outside the horizontal range suitable for being gripped by the jaws, requiring readjustment of the position of the movable jaw mechanism 60, or the position of the web cross bar 99, for example.

When the reinforcing mesh grabbing device continuously descends, the two hook-shaped clamping jaw single bodies 64 are in an open state, a downward opening with a large lower part and a small upper part is formed, and the movement of the mesh transverse rib 99 and the clamping jaw driving piece 62 can be guided. The corresponding position of the mesh sheet transverse rib 99 right below the movable clamping jaw mechanism 60 is different from the distance of the mesh sheet transverse rib 99 lifted by the fixed clamping jaw mechanism 24, so that when the reinforcing steel bar mesh sheet 90 is grabbed by the reinforcing steel bar mesh sheet grabbing device, great stress is not generated on the reinforcing steel bar mesh sheet 90 or the reinforcing steel bar mesh sheet grabbing device, and the loss of parts of the reinforcing steel bar mesh sheet grabbing device is reduced.

The descending limit position of the steel mesh gripping device is the position where the second sensor 68 senses the sensing plate 662, otherwise damage to the steel mesh gripping device or the steel mesh 90 may be caused.

Even if the jaw driving member 62 is not completely moved in place during the descending process of the steel mesh gripping device, the jaw driving member 62 can overcome the elastic force of the horizontal elastic member 69 by using the counterforce of the mesh transverse rib 99 on the two hook-shaped jaw single bodies 64 in the process of driving the two hook-shaped jaw single bodies 64 to be folded by the jaw driving member 62, so that the movable jaw mechanism 60 is aligned with the mesh transverse rib 99.

After the two hook-shaped jaw single bodies 64 are closed in place by the jaw driving member 62, the mesh cross bar 99 is located above the horizontal portions 641 of the hook-shaped jaw single bodies 64, and the weight of the reinforcing mesh 90 is borne by each horizontal portion 641. Then, the reinforcing mesh sheet 90 can be transported to a proper position by using the reinforcing mesh sheet grabbing device, and the clamping jaw driving piece 62 drives the two hook-shaped clamping jaw single bodies 64 to be opened, so that the reinforcing mesh sheet 90 is released.

The application also provides a prefabricated component production facility, including above-mentioned reinforcing bar net piece grabbing device.

Through set up above-mentioned reinforcing bar net piece grabbing device in prefabricated component production facility, correspondingly, this prefabricated component production facility has above-mentioned reinforcing bar net piece grabbing device's all advantages, no longer gives unnecessary details one by one here.
