Description

Technical Field

[0001] The invention belongs to the technical field of automobile roof production, in particular to an automatic cutting and feeding device for automobile roof production. Background Art

[0002] The car roof is an important part of the interior of the car and has multiple functions and effects. During the production and processing of the car roof, the opening of the skylight part needs to be flanging. In order to ensure the quality of the flanging, the PU foam at the skylight opening of the car roof needs to be cut to make way for the flanging. After the cutting work is completed, the feeding device needs to be used to send the cut car roof to the next process for processing.

[0003] The patent with announcement number CN215919440U discloses an automatic cutting and feeding device for automobile roof production, including a base, the upper end of the base is fixedly connected to a support plate, the middle part of the base is fixedly connected to a middle plate, two groups of clamping and positioning components are arranged vertically and horizontally inside the base, the upper end of the base is provided with a transmission component, and the upper end of the support plate is provided with a cutting component; in the technical solution provided by the patent, by setting a clamping and positioning component and a cutting component, the clamping and positioning component includes a fixing part, a gear, a motor, a belt, a first slider, a second slide rail, a third slide rail, a second slider and an electric telescopic rod, and the elasticity of the belt and the advantages of mitigating impact and vibration loads are utilized to achieve a smooth driving of the sliders at both ends to move along the running direction of the belt, thereby achieving the continuous clamping and positioning effect of the electric telescopic rod on the automobile roof, and the operating arm can automatically and flexibly control the rotation direction and cutting trajectory through the control box and the slide rail.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Although rollers can be used to transfer the cut car roofs to a designated location and enter the next process, when multiple car roofs need to be cut, the cut car roofs are moved to the next process one by one. In some cases, in order to improve the subsequent processing efficiency of the car roofs and the connection efficiency between processes, multiple car roofs need to arrive at the subsequent process at the same time. When the car roofs are moved to the next process one by one, the subsequent processing efficiency of the car roofs will be affected. In addition, in some cases, after the same batch of car roofs are cut, workers need to check the cutting quality of the car roofs one by one. Only the car roofs with qualified cutting quality can enter the next process for processing, and the car roofs with unqualified cutting quality need to be discarded to avoid defective products in subsequent processing. When multiple car roofs are placed on rollers in a relatively scattered state, it is not conducive to the workers' inspection. Frequent and large-scale movement of the body and line of sight are required, which can easily cause fatigue to the workers. When the workers stand in a fixed position and inspect each car roof after cutting is completed, and continue to transport the car roofs after the inspection is completed, it is not conducive to comparing the cutting quality of multiple car roofs in the same batch, which affects the accuracy of the inspection results.

[0047] Specifically, when the existing automatic cutting and feeding device for automobile roof production is used, although the cut automobile roof can be conveyed to the designated position by rollers and enter the next process, when multiple automobile roofs need to be cut, the cut automobile roofs are moved to the next process one by one. In some cases, in order to improve the subsequent processing efficiency of automobile roofs and the connection efficiency between processes, multiple automobile roofs need to arrive at the subsequent process at the same time. When the automobile roofs are moved to the next process one by one, the subsequent processing efficiency of the automobile roofs will be affected. In addition, in some cases, after the same batch of automobile roofs are cut, workers need to follow The cutting quality of the car roof is checked once. Only the car roof with qualified cutting quality can enter the next process for processing. The car roof with unqualified cutting quality needs to be eliminated to avoid defective products in subsequent processing. When multiple car roofs are placed on the roller in a relatively scattered state, it is not conducive to the inspection of workers. Frequent and large-scale movement of the body and sight is required, which easily causes fatigue to the workers. The workers stand in a fixed position and check each car roof after cutting. When the car roof is transported after the inspection is completed, it is not conducive to comparing the cutting quality of multiple car roofs in the same batch, affecting the accuracy of the inspection results.

[0048] Therefore, in order to solve the above-mentioned problem, this embodiment is used for the same batch of automobile roofs with the same specifications; according to the size of the automobile roof, the motor three 20, the motor four 23, and the motor ten 43 are started respectively. When the motor three 20 drives the threaded rod three 15 to rotate, the displacement plate 41 can be moved to adjust the distance between the displacement plate 41 and the positioning plate 42. At the same time, the motor four 23 drives the two-way threaded rod one 22 to rotate, and the motor ten 43 drives the two-way threaded rod two 44 to rotate, so as to adjust the distance between the two limit plates one 17 and the two limit plates two 24, so that the cut automobile roof can be moved to the rectangular range formed by the two limit plates one 17 and the two limit plates two 24. When the cut automobile roof moves to the support plate 35 along with the transmission roller 16, the edge of the automobile roof will fit the inner angle of the support plate 35. At this time, the motor 8 36 drives the threaded rod 7 38 to rotate, so that the pressure plate 37 descends and presses the edge of the automobile roof. Then the motor 9 39 drives the threaded rod 6 34 to rotate, so that the slide plate 3 31 rises, and the automobile roof can be raised. When the automobile roof is higher than the upper end surface of the uppermost inclined block 18, the motor 2 19 drives the threaded rod 2 12 to rotate, so that the connecting rod 13 descends, and multiple push rods 14 can be simultaneously descended and contact the inclined block 18. Since the contact surface between the inclined block 18 and the push rod 14 is an inclined surface, the inclined block 18 will be pushed by the push rod 14. The push rod 14 is moved, the spring 21 is compressed, and a bulge is formed on one side of the limit plate 17 and the limit plate 24. At this time, the pressure plate 37 can loosen the car roof, and the four corners of the car roof will contact and be supported by the inclined block 18, so that the car roof can be placed. Then repeat the above work. As the push rod 14 descends, multiple inclined blocks 18 can support the car roof. When all the cut car roofs of the same batch are placed, at this time, the four corners of the multiple car roofs are aligned, and then the push rod 14 is driven to rise, so that the push rod 14 is away from the inclined block 18, and the inclined block 18 will be reset under the recovery of the spring 21, so that multiple car roofs can be simultaneously moved along the limit plate 17 and the limit plate 24. The edge of the automobile roof slides onto the transmission roller 16, and the multiple automobile roofs that have slid down are in a stacked state, and then the motor five 26 drives the threaded rod four 27 to rotate, so that the baffle plate 25 slides on the limit plate two 24, so that the baffle plate 25 no longer blocks the automobile roof. At this time, the stacked automobile roofs can be sent to the next process under the action of the transmission roller 16, so that multiple automobile roofs can reach the subsequent processing process at the same time, thereby improving the subsequent processing efficiency of the automobile roof and the connection efficiency between the processes, and the number of automobile roofs stacked at one time can also be controlled by controlling the number of reset inclined blocks 18, so that batch quantitative feeding can be realized, and thus different actual processing needs can be met;

[0049] Moreover, when a plurality of car roofs that have been cut are placed on the inclined block 18, the motor 10 can be used to drive the threaded rod 11 to rotate, so that the mounting plate 9 can be raised or lowered. The worker only needs to maintain a fixed position and a fixed viewing angle to inspect the cutting quality of a plurality of car roofs, thus avoiding the process of frequently moving the body and viewing angle, reducing the labor intensity of the workers, and since a plurality of car roofs are relatively concentrated, it is also convenient for the workers to compare the cutting quality of a plurality of car roofs, which is conducive to improving the inspection efficiency. At the same time, since there is a certain distance between the plurality of car roofs, there will be no situation in which the accuracy of the inspection result is affected by the mutual covering of the car roofs.

[0050] When the worker finds a car roof with unqualified cutting quality, if the car roof is between two car roofs, the baffle 25 can be driven to move so that the baffle 25 no longer blocks the car roof, and then the car roof with unqualified cutting quality can be clamped by the above-mentioned support plate 35 and pressure plate 37, and then the motor 7 32 is used to drive the threaded rod 8 40 to rotate, so that the slide plate 28 slides to the right, and the car roof is pulled out from between the limit plate 1 17 and the limit plate 24, and then the motor 6 29 is used to drive the threaded rod 5 30 to rotate, so that the car roof is moved away from the top of the transmission roller 16. In addition, the worker can place a collection container on one side of the frame 1 to collect the car roof with unqualified cutting quality, so that the car roof with unqualified cutting quality can be removed after the cutting quality inspection work is completed, avoiding the car roof with unqualified cutting quality being placed together with other car roofs with qualified quality when the car roofs are stacked and transported, which leads to the situation of defective products in subsequent processing.

[0051] Working principle: Place the car roof on the transmission roller 16, and transport the car roof by rotating the transmission roller 16. This transportation method is the existing technology. When the car roof moves between the two fixed plates 4, the electric push rods 2 on both sides are started at the same time and drive the two fixed plates 4 to approach each other to clamp the car roof. At this time, the robot arm 6 can be used with the laser cutting head 7 to cut the car roof, and then start the motor three 20, the motor four 23, and the motor ten 43 according to the size of the car roof. When the motor three 20 drives the threaded rod three 15 to rotate, the displacement plate 41 can be moved to adjust the distance between the displacement plate 41 and the positioning plate 42. At the same time, the motor four 23 drives the bidirectional threaded rod one 22 to rotate, and the motor ten 43 drives the bidirectional threaded rod two 4 4 is rotated to adjust the spacing between the two limit plates 17 and the two limit plates 24, so that the cut automobile roof can be moved to the rectangular range formed by the two limit plates 17 and the two limit plates 24. When the cut automobile roof moves to the support plate 35 along with the transmission roller 16, the edge of the automobile roof will fit with the inner angle of the support plate 35. At this time, the motor 8 36 drives the threaded rod 7 38 to rotate, so that the pressing plate 37 descends and presses the edge of the automobile roof. Then the motor 9 39 drives the threaded rod 6 34 to rotate, so that the chute plate 31 rises, and the automobile roof can be raised. When the automobile roof is higher than the upper end surface of the uppermost inclined block 18, the motor 2 19 drives the threaded rod 2 12 to rotate, so that the connecting rod 13 descends, so that the multiple push rods 14 can be simultaneously When the push rod 14 is lowered, the plurality of inclined blocks 18 can support the car roof. When all the cut car roofs of the same batch are placed, the four corners of the car roofs are aligned, and then the push rod 14 is driven to rise, so that the push rod 14 is away from the inclined block 18. The inclined block 18 will be reset under the recovery of the spring 21, and the car roof can be placed. A plurality of automobile roofs slide down onto the transmission roller 16 along the edges of the limiting plate 1 17 and the limiting plate 2 24 at the same time, and the sliding automobile roofs are in a stacked state, and then the motor 5 26 drives the threaded rod 4 27 to rotate, so that the baffle 25 slides on the limiting plate 24, so that the baffle 25 no longer blocks the automobile roof. At this time, the stacked automobile roofs can be sent to the next process under the action of the transmission roller 16, so that a plurality of automobile roofs can reach the subsequent processing process at the same time, thereby improving the subsequent processing efficiency of the automobile roofs and the connection efficiency between the processes, and the number of automobile roofs stacked at one time can also be controlled by controlling the number of reset inclined blocks 18, so that batch quantitative feeding can be realized, and thus different actual processing requirements can be met;Furthermore, when a plurality of car roofs that have been cut are placed on the inclined block 18, the motor 10 can be used to drive the threaded rod 11 to rotate, so that the mounting plate 9 can be raised or lowered. The worker only needs to maintain a fixed position and a fixed viewing angle to inspect the cutting quality of a plurality of car roofs, thus avoiding the process of frequently moving the body and viewing angle, reducing the labor intensity of the workers, and since a plurality of car roofs are relatively concentrated, it is also convenient for the workers to compare the cutting quality of a plurality of car roofs, which is conducive to improving the inspection efficiency. At the same time, since there is a certain distance between the plurality of car roofs, there will be no situation in which the accuracy of the inspection result is affected by the mutual covering of the car roofs. When the worker finds a car roof with unqualified cutting quality, if the car roof is between two car roofs, the baffle 25 can be driven to move so that the baffle 25 can be moved. The plate 25 no longer blocks the car roof, and the car roof with unqualified cutting quality is clamped by the above-mentioned supporting plate 35 and pressing plate 37, and then the motor 7 32 drives the threaded rod 8 40 to rotate, so that the slide plate 2 28 slides to the right, and the car roof is pulled out from between the limit plate 1 17 and the limit plate 2 24, and then the motor 6 29 drives the threaded rod 5 30 to rotate, so that the car roof is moved away from the top of the transmission roller 16, and the worker can place a collection container on one side of the frame 1 to collect the car roof with unqualified cutting quality, so that the car roof with unqualified cutting quality can be removed after the cutting quality inspection work is completed, avoiding the car roof with unqualified cutting quality being placed together with other car roofs with qualified quality when the car roof is stacked and transported, which leads to the situation of defective products in subsequent processing. ;
