A V-shaped groove 4 for limiting the rolling of the pull rod is provided on the placement block 3. The pull rod can be placed in more than two rows of corresponding V-shaped grooves 4 by a crane. After the pull rod is placed, the robot grabs the pull rod in the V-shaped groove 4 and places it on other machines for processing.

[0003] The existing tie rod frame can only accommodate one layer of tie rods. Not only does the space utilization of the tie rod frame be low, but the alternation frequency between the manipulator grabbing the material and the manual operation loading is also very high, resulting in low efficiency of the manipulator operation and high intensity of manual operation. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the existing pull rod frame, such as low space utilization, low robot operation efficiency and high manual labor intensity, and provides a pull rod frame and a pull rod placement device for continuous operation of an assembly line.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0007] By adopting the above scheme, the first V-shaped positioning blocks provided on the two support frames can be used to place the pull rods, and when the pull rods in the first V-shaped positioning blocks on the two support frames are placed, the two placement frames connected by the connecting beam can be stacked on the two support frames. In the process of stacking the two support frames, the second V-shaped positioning blocks provided at the lower ends of the placement frames will abut against the pull rods placed in the first V-shaped positioning blocks. At this time, the pull rods will guide the second V-shaped positioning blocks, thereby guiding the stacking of the placement frames. When the placement frames are stacked on the support frames, the pull rods can be The rod is placed in the second V-shaped positioning block on the two placement racks, and then the steps are repeated to stack the other placement racks. After the stacking is completed, the robot can be used to grab the pull rod in the second V-shaped positioning block placed on the top layer. When the pull rods in the second V-shaped positioning block of the top layer are taken out, the robot can be controlled to remove the top placement rack, and then the robot can continue to grab the pull rod on the next layer of placement rack. The same principle is used for subsequent operations, thereby reducing the frequency of alternation between manual and robot loading, improving production efficiency, and also improving space utilization.

[0008] Preferably, longitudinal guide components are provided between the placement modules and the stacking components, and between the stacking components, for driving the two to be stacked neatly.

[0009] Preferably, the longitudinal guide component includes a longitudinal guide block that extends downward on a side opposite to the placement rack and can be inserted along the side wall of the lower support rack or the side opposite to the placement rack.

[0010] By adopting the above scheme, by setting a longitudinal guide block extending downward on the opposite side of the placement rack, the stacking of the placement racks can be guided when the placement racks are stacked on the support rack or the placement rack, thereby facilitating the stacking of the placement racks on the support rack or the placement rack and making the stacked placement racks and the support racks more neat.

[0011] Preferably, the bottom of the opposite side of the longitudinal guide block is provided with an introduction slope for facilitating its introduction along the side wall opposite to the supporting frame or placement frame below.

[0012] By adopting the above solution, by setting the introduction slope at the bottom of one side opposite to the longitudinal guide block, the trouble caused by the longitudinal deviation between the two when the placement rack is stacked on the support rack or other placement rack can be reduced.

[0013] Preferably, the support frame is embedded and slidably mounted on the frame body and can be relatively close to or far away from the frame body.

[0017] Preferably, a pull rod placement device for continuous operation of an assembly line is provided with at least two of the above-mentioned pull rod frames, including a workbench, and a quick alignment structure is provided between the frame body and the workbench.

[0018] By adopting the above scheme, when at least two pull rod frame structures are set, the robot can grab the empty placement rack after grabbing all the pull rods on the placement rack and place the empty placement rack into other empty frame bodies. When all the pull rods in the frame body are taken out, the entire frame body can be removed from the workbench, and a new frame body with pull rods inside can be placed on the workbench, thereby realizing continuous operation.

[0019] Preferably, the quick alignment structure includes columns with positioning slots at the bottom that are vertically downwardly arranged at the four corners of the lower end of the frame body, and positioning pins that are fixed to the workbench and can be inserted into the positioning slots.

[0020] With the above solution, the positioning pins provided on the workbench can be gradually inserted into the positioning grooves at the bottom of the columns when the frame body is placed on the workbench, thereby positioning the frame body when it is placed on the workbench.

[0021] Preferably, the positioning groove and the positioning pin are in the shape of a frustum with a small top and a large bottom.

[0022] By adopting the above solution, the shapes of the positioning grooves are set to be a cone with a small top and a large bottom, so that it can not only be positioned when the frame body is placed on the workbench, but also guide the insertion between the positioning grooves and the positioning pins.

[0023] Preferably, a sensor is provided on the workbench to detect whether the positioning pin is aligned with the positioning groove.

[0024] By adopting the above solution, the alignment between the locating pin and the locating slot can be fed back through the set sensor. When the locating pin on the workbench is inserted into the locating slot at the bottom of the column, the position of the frame body can be positioned at this time, and the robot can accurately grasp the pull rod inside the frame body.

[0025] The utility model has a significant technical effect due to the adoption of the above technical solution: the first V-shaped positioning blocks provided on the two support frames can be used to place the pull rods, and when the pull rods in the first V-shaped positioning blocks on the two support frames are placed, the two placement frames connected by the connecting beam can be stacked on the two support frames, and in the process of stacking the two support frames, the second V-shaped positioning blocks provided at the lower ends of the placement frames will abut against the pull rods placed in the first V-shaped positioning blocks, and at this time the pull rods will guide the second V-shaped positioning blocks, thereby guiding the stacking of the placement frames, and when the placement frames are stacked on the support frames, the second V-shaped positioning blocks will abut against the pull rods placed in the first V-shaped positioning blocks. When the rack is placed, the pull rod can be placed in the second V-shaped positioning block on the two racks, and then the steps can be repeated to stack the other racks. After the stacking is completed, the robot can be used to grab the pull rod in the second V-shaped positioning block on the top layer. When the pull rod in the second V-shaped positioning block of the top layer is taken out, the robot can be controlled to remove the top rack, and then the robot can continue to grab the pull rod on the rack on the next layer. The same principle can be used in the subsequent steps, thereby reducing the frequency of alternation between manual and robotic loading, improving production efficiency, and also improving space utilization.

[0036] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0037] Example

[0038] A pull rod frame and a pull rod placement device for continuous operation of an assembly line, comprising a workbench 11 and a frame body 1 that can be detachably arranged on the workbench 11 through a quick alignment structure, a placement module connected to the frame body 1, the placement module comprising at least two support frames 2 arranged in parallel and spaced relation on the frame body 1 and a number of one-to-one corresponding first V-shaped positioning blocks 501 arranged on the upper end faces of adjacent support frames 2, the support frames 2 being embedded and slidable on the frame body 1 and being relatively close to or far away from each other, a number of stacking placement components that can place a layer of pull rods separately are longitudinally stacked on the placement module, the stacking placement components comprising a placement frame 6 mounted on the upper end of the support frame 2 and a connecting beam 7 that fixedly connects adjacent placement frames 6, second V-shaped positioning blocks 502 with opposite opening directions are fixed to the upper and lower end faces of the placement frame 6, in this embodiment, seven second V-shaped positioning blocks 502 are respectively arranged at the upper and lower ends of a single placement frame 6, and symmetrically provided with lifting rings 10 on the outer wall of the frame body 1 for facilitating the movement of the frame body 1 by a vehicle.

[0039] Longitudinal guide components are provided between the placement module and the stacking placement components, and between the stacking placement components, to drive the two to be stacked neatly. The longitudinal guide components include a longitudinal guide block 8 that extends downward on the side opposite to the placement rack 6 and can be inserted along the side wall opposite to the support rack 2 below or the placement rack 6. The bottom of the longitudinal guide block 8 on the opposite side is provided with an introduction slope 9 for facilitating its introduction along the side wall opposite to the support rack 2 below or the placement rack 6.

[0040] The quick alignment structure includes columns 15 with positioning grooves 12 at the bottom, which are vertically arranged at the four corners of the lower end of the frame body 1, and positioning pins 13 fixed on the workbench 11 and can be inserted into the positioning grooves 12. The positioning grooves 12 and the positioning pins 13 are frustum-shaped with a small top and a large bottom.

[0041] A sensor 14 is provided on the workbench 11 to detect whether the positioning pin 13 is aligned with the positioning groove 12 .

[0042] In this embodiment, the manipulator grabs the tie rod seven times and then removes the empty placement rack 6 from the frame body 1 , and the manipulator grabs the tie rod or the placement rack 6 under program control.

[0043] Specific stacking steps: When the pull rod needs to be placed on the frame body 1, the pull rod can be placed in the first V-shaped positioning block 501 on the support frame 2 in sequence. When the first V-shaped positioning block 501 on the support frame 2 is equipped with a pull rod, a placement rack 6 connected to each other by a connecting beam 7 can be moved at this time, and the placement rack 6 can be stacked above the first V-shaped positioning block 501. In the process of stacking the placement racks 6, the introduction slope 9 on the longitudinal guide block 8 on the placement rack 6 will guide the stacking of the placement rack 6 longitudinally, lowering the placement rack 6 when it is stacked on the support frame 2. When the rack 6 is stacked on the support frame 2, the longitudinal deviation between the two causes trouble for the stacking of the rack 6. At the same time, the second V-shaped positioning block 502 set at the lower end of the rack 6 will also contact the pull rod placed in the first V-shaped positioning block 501. At this time, the pull rod will guide the second V-shaped positioning block 502, reducing the trouble caused by the lateral deviation between the two when the rack 6 is stacked on the support frame 2, thereby improving the neatness of the rack 6 when it is stacked on the support frame 2. Afterwards, the pull rods are placed in the second V-shaped positioning block 502 above the rack 6 in sequence. , when the pull rods are installed in the second V-shaped positioning blocks 502 on the placement rack 6, the above steps can be repeated to stack the other placement racks 6. When the placement racks 6 in the frame are stacked, the crane can be operated to place the frame body 1 on the workbench 11. When the frame body 1 is moved to the workbench 11, the positioning grooves 12 at the bottom of the columns 15 around the frame body 1 and the positioning pins 13 on the workbench 11 can be used to position the frame body 1. When the frame body 1 is positioned and installed on the workbench 11, the robot can grab the top layer. The pull rods on the placement rack 6 are taken out by the robot, and when the robot has taken out all the pull rods in the placement rack 6 on the top layer, the robot can be controlled to remove the placement rack 6 on the top layer from the frame body 1 and place it in other empty frame bodies 1 for storage. After that, the robot can continue to grab the pull rods on the placement rack 6 on the next layer, and the same applies to the subsequent ones. When the pull rods on the support frame 2 are grabbed by the robot, the frame body 1 can be removed from the workbench 11 by the crane and replaced with a new frame body 1 with a pull rod inside, thereby increasing the working time of the robot after manual loading once and improving production efficiency.
