Description

Technical Field

[0001] The invention belongs to the field of stacking equipment, and in particular relates to an automobile aluminum bar stacking production line. Background Art

[0002] The function of the stacking equipment can be briefly described as follows: the objects to be stacked are sent to the stacking platform through a conveyor, and then the objects are transferred to be positioned on the cart. During these working processes, it is usually necessary to manipulate the orientation of the objects so that they are correctly positioned. In actual design, the stacking method must be designed according to the shape of the objects to be stacked, so as to achieve a structure with optimal stacking strength and stacking volume.

[0003] Especially for automotive aluminum bar workpieces, the texture of the aluminum bars is relatively soft, so when stacking the aluminum bars, spacers need to be placed between the aluminum bars and then stacked on a cart to prevent extrusion and wear between the aluminum bars. Spacers need to be placed under the aluminum bars. In the prior art, the stacking of aluminum bars mostly relies on robotic arms to grab, but due to the inaccurate placement of the cart and the spacers, the robot's gripper has a high error rate in grabbing the spacers and is prone to collision with the cart.

DETAILED DESCRIPTION

[0047] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0048] like Figures 1 to 9 As shown, the automotive aluminum bar stacking production line includes: a spacer bar conveying mechanism, which is used to store and deliver the spacers; a spacer bar positioning mechanism, whose end intersects with the spacer bar conveyor, and the spacer bar positioning mechanism is used to receive the spacers delivered by the spacer bar conveying mechanism and position the spacers; a manipulator mechanism, which is located on the side of the spacer bar positioning mechanism, and the manipulator mechanism is used to grab the spacers on the spacer bar positioning mechanism; a trolley placement mechanism, which is located on the side of the manipulator mechanism, and a positioning space 28 is opened in the trolley placement mechanism, and a trolley 35 is arranged in the positioning space 28; when the manipulator mechanism grabs the spacer bar on the spacer bar positioning mechanism, the spacer bar can be placed in the trolley 35.

[0049] The spacer bar conveying mechanism can store the spacer bars. When the spacer bars are needed, the spacer bar conveying mechanism can deliver the spacer bars to the spacer bar positioning mechanism. When the spacer bars are delivered into the spacer bar positioning mechanism, the spacer bar positioning mechanism can position the spacer bars. Then the aluminum bars can be placed on the spacer bars. The robot mechanism then grabs the spacer bars and drives them to move. In this way, the aluminum bars can be driven to move at the same time. Because the spacer bars are positioned on the spacer bar positioning mechanism, the position of the robot mechanism clamping the spacer bars is fixed. In this way, the situation where the robot mechanism clamps the spacer bars empty can be avoided.

[0050] After the robot mechanism clamps the spacer bar, the robot mechanism drives the spacer bar and the aluminum bar to move toward the cart placement mechanism, and finally places the spacer bar on the cart 35. The cart 35 is located in the positioning space 28, that is, the position of the cart 35 is also fixed, which greatly avoids the collision between the robot mechanism and the cart 35.

[0051] The partition bar conveying mechanism includes: a support frame, 1; a partition bar storage assembly, which is arranged on the support frame, 1, and a first conveyor belt 2 is arranged on the partition bar storage assembly, and the first conveyor belt 2 is used to drive the bottom layer of partition bars of the partition bar storage assembly to move; a partition bar conveying assembly, which is arranged on the support frame, 1, and the partition bar conveying assembly is used to receive the bottom layer of partition bars of the partition bar storage assembly and drive the partition bars at the front end to move.

[0052] The partition bar storage assembly is used to store the partition bars to be transported. The first conveyor belt 2 can drive the partition bars located at the bottom layer of the partition bar storage assembly to move. The partition bar conveying assembly can receive several partition bars sent by the first conveyor belt 2 and send the front partition bar to the partition bar positioning assembly. The partition bar conveying assembly sends the single partition bars to the partition bar positioning assembly in turn, so that the partition bar positioning assembly can position the single partition bars respectively.

[0053] The spacer bar storage assembly includes: a spacer bar storage frame 3, which is mounted on the support frame 1 and is located above the first conveyor belt 2; a limiting cylinder 4, which is mounted on the support frame 1, and a limiting bar 5 is arranged on the limiting cylinder 4, and the limiting bar 5 is movably inserted in the spacer bar located at the bottom layer of the spacer bar storage frame 3; a supporting member 36, which is movably arranged on the support frame 1, and the supporting member 36 is located below the spacer bar storage frame 3, and when the supporting member 36 moves upward, it can abut against the spacer bar located at the bottom layer of the spacer bar storage frame 3; when the spacer bar located at the bottom layer of the spacer bar storage frame 3 abuts against the supporting member 36, the limiting cylinder 4 drives the limiting bar 5 to detach from the spacer bar, and when the supporting member 36 moves downward, the spacer bar can be placed on the first conveyor belt 2.

[0054] The spacer bar storage frame 3 is used to place the spacer bars, and the limiting cylinder 4 is provided with a limiting bar 5, which is inserted into the spacer bars located at the bottom layer of the spacer bar storage frame 3, so that the spacer bars will not be separated from the spacer bar storage frame 3. Because the spacer bar storage frame 3 is located above the first conveyor belt 2, when the limiting bar 5 is inserted into the spacer bars, the spacer bars cannot fall onto the first conveyor belt 2, and thus the first conveyor belt 2 cannot transport the spacer bars. The supporting member 36 is arranged below the spacer bar storage frame 3, and when the supporting member 36 moves upward, it can abut against the spacer bars located at the bottom layer of the spacer bar storage frame 3, so as to support the spacer bars. At this time, the limiting cylinder 4 drives the limiting bar 5 to separate from the partition bar, and the partition bar is no longer restricted. At this time, when the supporting member 36 moves downward, the partition bar can move downward at the same time. When the partition bar moves downward to the height of a partition bar, the limiting cylinder 4 drives the limiting bar 5 to move again, so that the limiting bar 5 is inserted into the second-to-last layer of partition bars, and then the supporting member 36 continues to descend. At this time, the supporting member 36 can drive a layer of partition bars to move downward, and then the supporting member 36 continues to move downward, so that the partition bar is placed on the first conveyor belt 2, and when the first conveyor belt 2 rotates, it can drive several partition bars to move.

[0055] In the support frame diagram, a limiting cylinder 6 is provided on 1, and a limiting plate 7 is provided on the first limiting cylinder 6, and the limiting plate 7 is located on the side of the first conveyor belt 2; when the limiting cylinder 6 drives the limiting plate 7 to move downward, the partition bar on the first conveyor belt 2 can be driven to move.

[0056] The limit plate 7 can be driven by the limit cylinder 6 to move up and down. When the limit plate 7 moves upward, the limit plate 7 can rest against the partition bar of the first conveyor belt 2. Even if the first conveyor belt 2 rotates, it cannot drive the partition bar to move forward. When the partition bars on the partition bar conveying assembly are used up, the limit plate 7 moves downward, and the partition bars are no longer restricted, so that the first conveyor belt 2 can drive the partition bars to move, and then send the partition bars to the partition bar conveying assembly.

[0057] The partition bar conveying assembly includes: a second conveyor belt 8, which is arranged on the support frame 1 in the figure, and the end of the second conveyor belt 8 intersects with the end of the first conveyor belt 2; a stop cylinder 9, which is connected to the support frame 1 in the figure, and a stop plate 10 is arranged on the upper end of the stop cylinder 9, and the stop plate 10 is located on the side of the second conveyor belt 8 and is movably pressed against the partition bar; a gripping member, which is arranged on the support frame 1 in the figure, and the horizontal vertical distance from the gripping member to the stop plate 10 is the same as the width of a partition bar, and the gripping member is used to grip the two ends of the partition bar.

[0058] The second conveyor belt 8 intersects with the first conveyor belt 2 , so that when the first conveyor belt 2 transports the spacer, the spacer can be sent to the second conveyor belt 8 , and then the second conveyor belt 8 continues to transport it.

[0059] The stop cylinder 9 can drive the stop plate 10 to move up and down, so that the stop plate 10 abuts against the partition bar on the second conveyor belt 8, preventing the partition bar from continuing to move forward, and then the gripping member grabs the partition bar. Because the lateral distance from the gripping member to the stop plate 10 is the same as the width of a partition bar, the stop cylinder 9 blocks the partition bar located at the front, and then the gripping member can grab the partition bar adjacent to the front partition bar. Then, the stop cylinder 9 moves downward. At this time, the second conveyor belt 8 can drive the front partition bar to move forward alone, thereby achieving the purpose of conveying one partition bar into the partition bar positioning assembly at a time.

[0060] The gripping member includes gripping cylinders 11 which are arranged opposite to each other on the support frame 1 in FIG. 1 , and the vertical distance between each gripping cylinder 11 and the stop plate 10 is equal to the width of a spacer bar.

[0061] The two gripping cylinders 11 can grip the partition bars. When the stop plate 10 moves downward to separate from the partition bars, the gripping cylinders 11 can ensure that the partition bars behind will not move forward. The vertical distance between each gripping cylinder 11 and the stop plate 10 is equivalent to the width of a partition bar, so the gripping cylinders 11 grip the second partition bar.

[0062] The spacer positioning mechanism includes: a third conveyor belt 12, which is arranged on the support frame Figure 1 and intersects with the end of the second conveyor belt 8; a plurality of groups of positioning members, which are evenly arranged on the support frame Figure 1, and the third conveyor belt 12 is located between the positioning members.

[0063] The third conveyor belt 12 intersects with the second conveyor belt 8, so that the partitions sent by the second conveyor belt 8 can be received by the third conveyor belt 12 and drive the partitions to move forward. A number of groups of positioning members are arranged on both sides of the third conveyor belt 12. The positioning members can position and clamp the partitions. The second conveyor belt 8 divides the partitions into pieces and transports them to the third conveyor belt 12 one by one. Therefore, when positioning the partitions, it is convenient to position them one by one. The third conveyor belt 12 is first positioned away from the second conveyor belt 8, and then the third conveyor belt 12 is positioned close to the second conveyor belt 8. The purpose of this is to evenly lay the partitions on the third conveyor belt 12.

[0064] Each group of positioning parts includes: two positioning cylinders 13 arranged opposite to each other on the support frame 1 in the figure, the third conveyor belt 12 is located between the two positioning cylinders 13, and a positioning plate 14 is arranged on the upper end of each positioning cylinder 13; a clamping plate 15, which is arranged on the support frame 1 and located on the side of the third conveyor belt 12; a clamping cylinder 16, which is arranged on the support frame 1 and located on the other side of the third conveyor belt 12, and a clamping block 17 is arranged at the end of the clamping cylinder 16; when the clamping cylinder 16 drives the clamping block 17 to move forward, the clamping block 17 can abut against the end of the partition bar and drive the other end of the partition bar to abut against the clamping plate 15.

[0065] The positioning cylinder 13 can drive the positioning plate 14 to rise or fall. When the positioning plate 14 moves upward, it can block the partition bar on the third conveyor belt 12 to prevent the partition bar from continuing to move forward after being sent to the predetermined position. At the same time, the partition bar can also be positioned. After the partition bar is positioned, the clamping cylinder 16 drives the clamping block 17 to move forward, thereby fixing the partition bar between the clamping plate 15 and the clamping block 17.

[0066] The robot mechanism includes: a mounting platform 18, which is located on the side of the third conveyor belt 12, and a robot arm 19 is arranged on the mounting platform 18; a mounting frame 20, which is connected to the robot arm 19, and the mounting frame 20 is provided with a connecting block 21, and a guide column 22 is longitudinally connected to the connecting block 21, and a spring 23 is sleeved on the guide column 22; a plurality of support columns 24, each support column 24 is slidably connected to the corresponding connecting block 21, and a clamping claw 25 is arranged at the lower end of each support column 24, and an abutment block 26 is arranged on the support column 24, and the abutment block 26 is connected to the lower end of the spring 23.

[0067] A mounting frame 20 is provided on the robotic arm 19, a connecting block 21 is provided on the mounting frame 20, a support column 24 is slidably connected to the connecting block 21, a spring 23 is provided on the guide column 22, and the lower end of the spring 23 is connected to the abutment block 26. When the clamp 25 encounters an obstacle and the robotic arm 19 still moves downward, the support column 24 can move upward on the connecting block 21, thereby preventing the clamp 25 from being crushed.

[0068] The trolley placement mechanism includes: a positioning frame 27, which is located on the side of the mounting platform 18, and a positioning space 28 is opened in the positioning frame 27; a lifting cylinder 29, which is connected to the positioning frame 27, and a lifting plate 30 is provided on the lifting cylinder 29, and the lifting plate 30 can lift the trolley 35 when it rotates; a side push cylinder 31, which is connected to the positioning frame 27, and a side push plate 32 is provided on the side push cylinder 31, and the side push plate 32 can drive the trolley 35 to move horizontally when it moves; a horizontal pulling cylinder 33, which is connected to the positioning frame 27, and a horizontal pulling plate 34 is provided on the horizontal pulling cylinder 33, and the horizontal pulling plate 34 can be inserted into the trolley 35 when it rotates and drive the trolley 35 to move longitudinally.

[0069] The positioning frame 27 is provided with a positioning space 28, which is used to accommodate the trolley 35 and position the trolley 35 in the positioning space 28. When the trolley 35 is positioned, the lifting cylinder 29 first drives the lifting plate 30 to rotate upward so that the lifting plate 30 can abut against the lower end surface of the trolley 35 until the lifting plate 30 drives the trolley 35 to rise to a certain height, thereby completing the vertical positioning of the trolley 35. Then, the side push cylinder 31 drives the side push plate 32 to abut against the trolley 35 and drives the trolley 35 to move horizontally until the trolley 35 is pushed into a predetermined horizontal position, thereby completing the horizontal position positioning of the trolley 35. Immediately afterwards, the horizontal pulling cylinder 33 drives the horizontal pulling plate 34 to rotate so that the upper end of the horizontal pulling plate 34 is inserted into the trolley 35, that is, the horizontal pulling plate 34 can hook the trolley 35. When the horizontal pulling plate 34 moves to the preset position, it can drive the trolley 35 to move to the preset position, thereby completing the longitudinal position positioning of the trolley 35.
