Description

Technical Field

[0001] This invention relates to the field of automation technology, specifically to an automated stacking process for cylinder heads. Background Technology

[0002] In the foundry industry, when using automated production lines to produce castings, the current equipment limitations mean that only one casting can be processed at a time, resulting in low production efficiency and failing to meet the requirements for increasing efficiency and expanding production. When producing different models of cylinder heads, it is necessary to manually change or adjust the clamping blocks, which leads to low production efficiency of the casting line, increases the labor intensity of operators, and also increases production costs.

[0003] In summary, there is an urgent need to provide an automated stacking process for cylinder heads that can reduce manual labor intensity and production costs. Summary of the Invention

[0004] The purpose of this invention is to provide an automated stacking process for cylinder heads that can reduce manual labor intensity and production costs.

[0005] The above objective is achieved through the following technical solution: an automated cylinder head stacking processing method, employing a stacking processing system. The stacking processing system includes a first conveyor line, a second conveyor line, a processing station, a splitting station, and a stacking station. The processing station is equipped with a processing device. Both the splitting and stacking stations are equipped with robot components. The first and second conveyor lines are arranged vertically. The second conveyor line transports materials sequentially along the stacking station, processing station, and splitting station. The conveying directions of the first and second conveyor lines are opposite. The stacking station is equipped with a first and second blocking positioning component for positioning materials. The splitting station is equipped with a third blocking positioning component for positioning materials. The method specifically includes the following steps:

[0006] (1) After the partition is loaded, it is conveyed to the partition positioning point of the stacking station through the first conveyor line;

[0007] (2) The cylinder head is transported to the stacking station via the second conveyor line. The first blocking and positioning component and the second blocking and positioning component block and position the two cylinder heads in turn. When the first blocking and positioning component blocks and positions the cylinder head, the robot component of the stacking station grabs the partition at the partition positioning point and places it on the cylinder head blocked and positioned by the first blocking and positioning component. When the second blocking and positioning component blocks and positions the cylinder head, the second conveyor line stops transporting the cylinder head.

[0008] (3) The robot component of the stacking station grabs the cylinder cover that is blocked and positioned by the second blocking and positioning component, flips it 180 degrees and places it on the partition in step (2) to form a cylinder cover stacking part, thus completing the stacking of the cylinder cover.

[0009] (4) The processing robot in the processing device grabs the cylinder head stacked parts in step (3) to the processing station for processing. The first blocking positioning component and the second blocking positioning component are reset. The second conveyor line continues to convey the cylinder head. While the processing station is processing the cylinder head, the stacking station continues to stack the cylinder head.

[0010] (5) The processing robot in the processing device places the processed cylinder head stack into the second conveyor line. The cylinder head stack is conveyed to the splitting station. The third blocking and positioning component blocks and positions the cylinder head stack. The robot component at the splitting station first splits the upper cylinder head of the cylinder head stack onto the second conveyor line to continue forward conveying for subsequent processes. Then, the middle partition is split onto the first conveyor line and returned to the partition positioning position. The third blocking and positioning component is reset. The lower cylinder head of the cylinder head stack continues to be conveyed forward for subsequent processes.

[0011] The spacer of this invention is used to separate the inner cavities of two cylinder heads, facilitating subsequent processing. It also enables the processing of two cylinder heads at once, increasing production efficiency. After processing, the spacer is positioned, and then a robotic automated device separates the two cylinder heads for subsequent processes. The spacer is transported by a first conveyor line. Once in place, it stops at a specific position (spacer positioning point) under the action of the positioning mechanism of the first conveyor line. A signal is transmitted to the robot component at the stacking station via a photoelectric switch, waiting for the robot component to grasp it.

[0012] A further technical solution is that the second conveyor line is equipped with a first position sensor, a second position sensor, and a third position sensor at the first blocking positioning component, the second blocking positioning component, and the third blocking positioning component, respectively. The first position sensor, the second position sensor, and the third position sensor are communicatively connected to the first blocking positioning component, the second blocking positioning component, and the third blocking positioning component, respectively. The first blocking positioning component and the second blocking positioning component are communicatively connected to the robot component of the stacking station. The third blocking positioning component is communicatively connected to the robot component of the splitting station. In step (2), after the first position sensor detects that the cylinder head has reached the predetermined position, it controls the first blocking positioning component to block and position the cylinder head, and at the same time, it feeds back a position signal to the robot component of the stacking station. The robot component of the stacking station grabs the spacer and stacks the cylinder head. The second position sensor... After the sensor detects that the cylinder head has reached the predetermined position, it controls the second blocking and positioning component to block and position the cylinder head. At the same time, it feeds back the position signal to the robot component at the stacking station. The robot component at the stacking station grabs the cylinder head positioned by the second blocking and positioning component and stacks it. In step (4), after the first or second position sensor detects that the cylinder head stack or the cylinder head has been grabbed, it controls the first and second blocking and positioning components to reset respectively. In step (5), after the third position sensor detects that the processed cylinder head stack has reached the predetermined position, it controls the third blocking and positioning component to block and position the cylinder head stack. At the same time, it feeds back the position signal to the robot component at the splitting station. The robot component at the splitting station splits the cylinder head stack. After the intermediate partition is placed in place, it transmits a signal to control the third blocking and positioning component to reset. The lower cylinder head continues to be conveyed forward.

[0013] A further technical solution is that the first blocking positioning component, the second blocking positioning component, and the third blocking positioning component all include a blocking mechanism, a lifting mechanism, and a positioning mechanism. The blocking mechanism and the lifting mechanism are located below the second conveyor line. The blocking mechanism includes a blocking bracket and a blocking drive component, and the blocking drive component is drivenly connected to the blocking bracket. The lifting mechanism includes a lifting frame and a lifting drive component, and the lifting drive component is drivenly connected to the lifting frame. The positioning mechanism includes a positioning drive component and clamping components located on both sides of the second conveyor line, and the positioning drive component is drivenly connected to the clamping components. In step (2), when the cylinder head on the second conveyor line is conveyed to the predetermined position, the blocking drive component drives the blocking bracket to rise and block the cylinder head. After the blocking drive component completes its stroke, it sends a positioning drive progressive signal to the positioning mechanism to drive the clamping components to move towards the middle of the second conveyor line to clamp and position the cylinder head. After the positioning drive component completes its stroke, it sends a lifting drive signal to the lifting mechanism to drive the lifting frame to move upward and lift the cylinder head to a certain height. Then, it sends a feedback signal to the robot component at the stacking station to perform the stacking action of the cylinder head.

[0014] A further technical solution is that the robot assembly includes a robot, a base, a pipeline package assembly, a connecting flange, and a stacking fixture. The robot is fixed in a predetermined position by the base, and the stacking fixture is connected to the end of the robot's six axes by the connecting flange. The air pipes and cables required for the stacking fixture are connected from the power source and air source through the pipeline package assembly.

[0015] A further technical solution is that the stacking fixture includes a fixture frame, and a linear guide rail, a hydraulic cylinder, a proximity switch, a fixed clamping arm assembly, and a movable clamping arm assembly disposed on the fixture frame. The movable clamping arm assembly is equipped with a rotary motor. Drawer guide rails are mounted on the fixed clamping arm assembly and the movable clamping arm assembly via an inner drawer guide rail seat and an outer drawer guide rail seat. In steps (2) to (5), the stacking fixture moves to the lifting mechanism under the drive of the robot, causing the lower clamping fingers on the fixed clamping arm assembly and the movable clamping arm assembly to approach the cylinder. Under the drive of the hydraulic cylinder, the moving arm assembly slides on the linear guide rail. After the proximity switch corresponding to the cylinder cover detects the position signal, the hydraulic cylinder holds pressure to clamp the cylinder cover. At the same time, it sends a signal to the drive components on the fixed clamping arm assembly and the moving clamping arm assembly to control the drive components to drive the upper clamping point to move downward, clamping the upper and lower surfaces of the cylinder cover. In step (3), under the drive of the rotary motor on the moving clamping arm assembly, the active shaft of the moving clamping arm assembly rotates, thereby driving the driven shaft on the fixed clamping arm assembly to rotate, so that the cylinder cover is flipped 180°.

[0016] In practical applications, proximity switches can be installed on the fixture frame according to the length of different cylinder head models and the clamping status of the cylinder head. The moving arm assembly slides on the linear guide rail. After the proximity switch of the corresponding cylinder head model detects the position signal, the hydraulic cylinder holds pressure to clamp the cylinder head. To ensure the rotation accuracy of the cylinder head, drawer guide rails are installed on the fixed clamping arm assembly and the moving clamping arm assembly so that the driven shaft rotates synchronously with the driving shaft.

[0017] A further technical solution is that the first position sensor, the second position sensor, and the third position sensor are photoelectric sensors.

[0018] A further technical solution is that the processing device is a shot blasting machine. Of course, other processing techniques are also possible.

[0019] Compared to existing technologies, the product of this invention features full-process automation, employing a cylinder head stacking and post-processing method, resulting in high work efficiency. The stacking fixture can adapt to various cylinder head models, ensuring good consistency and reducing manual labor intensity and production costs. Attached Figure Description

[0036] The present invention will now be described in detail with reference to the accompanying drawings. This description is merely illustrative and explanatory, and should not be construed as limiting the scope of protection of the present invention. Furthermore, those skilled in the art can combine the features in the embodiments described herein and in different embodiments accordingly based on the description in this document.

[0037] The embodiments of the present invention are as follows, such as Figure 1 An automated stacking processing method for cylinder heads is disclosed, employing a stacking processing system. The system includes a first conveyor line 1, a second conveyor line 2, a processing station 5, a splitting station 4, and a stacking station 3. The processing station 5 is equipped with a processing device. Both the splitting station 4 and the stacking station 3 are equipped with robot components 8. The first conveyor line 1 and the second conveyor line 2 are arranged vertically. The second conveyor line 2 transports materials sequentially along the stacking station 3, the processing station 5, and the splitting station 4. The conveying directions of the first conveyor line 1 and the second conveyor line 2 are opposite. The stacking station 3 is equipped with a first blocking positioning component 6 and a second blocking positioning component 7 for positioning materials. The splitting station 4 is equipped with a third blocking positioning component 10 for positioning materials. The method specifically includes the following steps:

[0038] (1) After the partition is loaded, it is conveyed to the partition positioning point 11 of the stacking station 3 through the first conveyor line 1;

[0039] (2) The cylinder head is transported to the stacking station 3 via the second conveyor line 2. The first blocking and positioning component 6 and the second blocking and positioning component 7 block and position the two cylinder heads in turn. After the first blocking and positioning component 6 blocks and positions the cylinder head, the robot component 8 of the stacking station 3 grabs the partition at the partition positioning point 11 and places it on the cylinder head blocked and positioned by the first blocking and positioning component 6. After the second blocking and positioning component 7 blocks and positions the cylinder head, the second conveyor line 2 stops transporting the cylinder head.

[0040] (3) The robot component 8 of the stacking station 3 grabs the cylinder cover that is blocked and positioned by the second blocking and positioning component 7, and flips it 180 degrees and places it on the partition in step (2) to form a cylinder cover stacking piece, thus completing the stacking of the cylinder cover.

[0041] (4) The processing robot 9 in the processing device grabs the cylinder head stacked part in step (3) and puts it into the processing device of the processing station 5 for processing. The first blocking positioning component 6 and the second blocking positioning component 7 are reset. The second conveyor line 2 continues to convey the cylinder head. While the processing station 5 is processing the cylinder head, the stacking station 3 continues to stack the cylinder head.

[0042] (5) The processing robot 9 in the processing device places the processed cylinder head assembly into the second conveyor line 2. The cylinder head assembly is conveyed to the splitting station 4. The third blocking and positioning component 10 blocks and positions the cylinder head assembly. The robot component 8 in the splitting station 4 first splits the upper cylinder head of the cylinder head assembly onto the second conveyor line 2 and continues to convey it forward for subsequent processes. Then, the middle partition is split onto the first conveyor line 1 and returned to the partition positioning point 11. The third blocking and positioning component 10 is reset, and the lower cylinder head of the cylinder head assembly continues to convey it forward for subsequent processes.

[0043] The partition of the present invention is used to separate the inner cavities of two cylinder heads, which facilitates subsequent processing and allows for the processing of two cylinder heads at the same time, increasing production efficiency. After processing, the partition is positioned and then the two cylinder heads are separated by a robot 16 automated equipment for subsequent processes. The partition is transported by the first conveyor line 1 and stops at a certain position (partition positioning point 11) under the action of the positioning mechanism 14 of the first conveyor line 1. A signal is transmitted to the robot component 8 of the stacking station 3 through a photoelectric switch, waiting for the robot component 8 to grasp it.

[0044] Based on the above embodiments, in another embodiment of the present invention, the second conveyor line 2 is provided with a first position sensor, a second position sensor, and a third position sensor at the first blocking positioning component 6, the second blocking positioning component 7, and the third blocking positioning component 10, respectively. The first position sensor, the second position sensor, and the third position sensor are communicatively connected to the first blocking positioning component 6, the second blocking positioning component 7, and the third blocking positioning component 10, respectively. The first blocking positioning component 6 and the second blocking positioning component 7 are communicatively connected to the robot component 8 of the stacking station 3, and the third blocking positioning component 10 is communicatively connected to the robot component 8 of the splitting station 4. In step (2), after the first position sensor detects that the cylinder head has reached the predetermined position, it controls the first blocking positioning component 6 to block and position the cylinder head, and at the same time, it feeds back a positioning signal to the robot component 8 of the stacking station 3. The robot component 8 of the stacking station 3 then grasps the spacer and performs... In step (4), after the first or second position sensor detects that the cylinder head has reached the predetermined position, it controls the second blocking and positioning component 7 to block and position the cylinder head, and at the same time feeds back the positioning signal to the robot component 8 of the stacking station 3. The robot component 8 of the stacking station 3 grabs the cylinder head positioned by the second blocking and positioning component 7 and stacks it. In step (5), after the first or second position sensor detects that the cylinder head stack or the cylinder head has been grabbed, it controls the first blocking and positioning component 6 and the second blocking and positioning component 7 to reset respectively. In step (5), after the third position sensor detects that the processed cylinder head stack has reached the predetermined position, it controls the third blocking and positioning component 10 to block and position the cylinder head stack, and at the same time feeds back the positioning signal to the robot component 8 of the splitting station 4. The robot component 8 of the splitting station 4 splits the cylinder head stack. After the intermediate partition is placed in place, it transmits a signal to control the third blocking and positioning component 10 to reset, and the lower cylinder head continues to be conveyed forward.

[0045] Based on the above embodiments, in another embodiment of the present invention, such as... Figures 2-5The first blocking positioning assembly 6, the second blocking positioning assembly 7, and the third blocking positioning assembly 10 each include a blocking mechanism 12, a lifting mechanism 13, and a positioning mechanism 14. The blocking mechanism 12 and the lifting mechanism 13 are disposed below the second conveyor line 2. The blocking mechanism 12 includes a blocking bracket 19 and a blocking drive component 20, which is drivenly connected to the blocking bracket 19. The lifting mechanism 13 includes a lifting frame 21 and a lifting drive component 22, which is drivenly connected to the lifting frame 21. The positioning mechanism 14 includes a positioning drive component 23 and clamps disposed on both sides of the second conveyor line 2. The positioning drive 23 is connected to the clamping member 24. In step (2), when the cylinder head on the second conveyor line 2 is conveyed to the predetermined position, the blocking drive 20 drives the blocking bracket 19 to rise and block the cylinder head. After the blocking drive 20 completes its stroke, it sends a positioning drive progressive signal to the positioning mechanism 14 to drive the clamping member 24 to move towards the middle of the second conveyor line 2 to clamp and position the cylinder head. After the positioning drive 23 completes its stroke, it sends a signal to the lifting drive 22 of the lifting mechanism 13 to drive the lifting frame 21 to move upward and lift the cylinder head to a certain height. Then, it sends a feedback signal to the robot component 8 of the stacking station 3 to perform the stacking action of the cylinder head.

[0046] Based on the above embodiments, in another embodiment of the present invention, such as... Figure 6 The robot assembly 8 includes a robot 16, a base 15, a pipeline package assembly 18, a connecting flange, and a stacking fixture 17. The robot 16 is fixed in a predetermined position by the base 15. The stacking fixture 17 is connected to the six-axis end of the robot 16 by the connecting flange.

Drawer guide rails are mounted on the fixed clamping arm assembly 26 and the movable clamping arm assembly 27 via an inner drawer guide rail seat and an outer drawer guide rail seat. In steps (2) to (5), the stacking clamp 17 moves to the lifting mechanism 13 under the drive of the robot 16, causing the lower clamps on the fixed clamping arm assembly 26 and the movable clamping arm assembly 27 to... The cylinder head is located near the bottom surface of the cylinder head. Under the drive of the hydraulic cylinder, the moving arm assembly slides on the linear guide rail 28. After the proximity switch corresponding to the cylinder head detects the position signal, the hydraulic cylinder holds pressure to clamp the cylinder head. At the same time, it sends a signal to the drive components on the fixed clamping arm assembly 26 and the moving clamping arm assembly 27 to control the drive components to drive the upper clamping point to move downward, clamping the upper and lower surfaces of the cylinder head. In step (3), under the drive of the rotary motor on the moving clamping arm assembly 27, the drive shaft of the moving clamping arm assembly 27 rotates, which in turn drives the driven shaft on the fixed clamping arm assembly 26 to rotate, causing the cylinder head to flip 180°.

[0048] In practical applications, proximity switches can be installed on the clamping frame 25 according to the length of different cylinder head models and the clamping state of the cylinder head. The moving arm assembly slides on the linear guide rail 28. After the proximity switch of the corresponding cylinder head model detects the position signal, the hydraulic cylinder holds pressure to clamp the cylinder head. To ensure the rotation accuracy of the cylinder head, drawer guide rails are installed on the fixed clamping arm assembly 26 and the moving clamping arm assembly 27 so that the driven shaft rotates synchronously with the driving shaft.

[0049] Based on the above embodiments, in another embodiment of the present invention, the first position sensor, the second position sensor and the third position sensor are photoelectric sensors.

[0051] Compared with existing technologies, the product of this invention is fully automated, adopts the method of cylinder head stacking and processing, which has high work efficiency. The stacking fixture 17 can adapt to various models of cylinder heads, with good consistency, reducing manual labor intensity and production costs.

[0052] For those skilled in the art, various improvements and modifications can be made without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
